Throughout This Semester I Have Learned A Lot From Family

Throughout this semester I have learned a lot from Family Relationships and Gender Roles. Although I have been fortunate to have very healthy and happy relationships in my life there is one past relationship I was a part of that was very toxic. It was with my ex-boyfriend of two years. Although the relationship ended over a year ago I feel as if the material we have discussed in class has in a way, provided some final closure for me. There have been many times in class when I have thought â€Å"Wow! Now, I can understand why that relationship wasn’t successful.† I can also admit that I have learned more about myself and the things I may have done that hindered the relationship. In order to analyze the past relationship, I will give some†¦show more content†¦Even looking back on the relationship I still can confidently say we communicated very well in the early stages of the relationship. I felt comfortable communicating with him about small conflicts or any of my wants and needs and I truly believe he felt the same way. Our communication didn’t seem to be an issue until after the first cheating incident. I think that this is because up until the cheating incident I had no reason to suspect he was not telling me things and I never felt a secretive or flighty vibe from him. After being cheated on I can admit that my communication skills with him started to change. Within one day everything had changed. I had not fallen out of love but instead of a sincere love it felt more like a constant sting to the heart whenever I thought of what he had done to me. I found myself bouncing back in forth between emotions of extreme hurt, anger, and self pity. Dr. Thompson talked to the class about the Four Horseman which are danger signals in a relationship. I realized that I could identify each of these danger signals within my past relationship. After being cheated on I think I subconsciously felt the need to make him feel the same pain that he had put me through. I used criticism as a way to make small jabs at him and tear him down. I knew I was able to get away with this because these small jabs paled in comparison to cheatingShow MoreRelatedThe Burden Of Knowing That People Around Me1076 Words   |  5 PagesFrom the very beginning of my life there has always been the burden of knowing that people around me do not want me to succeed.

Behavioral and Social/Cognitive Approaches to Forming Habits Free Essays

Habit as defined in Webster’s as a: a behavior pattern acquired by frequent repetition or physiologic exposure that shows itself in regularity or increased facility of performance b : an acquired mode of behavior that has become nearly or completely involuntary (Merriam-Webster Dictionary Online, 2011). Behavior is the manner of conducting oneself or anything that an organism does involving action and response to stimulation. In everyday life habits are formed and intertwined with ones behavior. We will write a custom essay sample on Behavioral and Social/Cognitive Approaches to Forming Habits or any similar topic only for you Order Now People are often associated with the way they behave based on the environment they come from and the habits they develop from that environment. Behavioral Theorists believe learning experiences as the development of our personality. During these developmental years the environment has the greatest influence on the personality. This influence is reinforced by positive or negative rewards. Classic conditioning explains many behavioral reaction patterns. When a person receives positive reinforcement of a behavior (reward), they develop this behavior as part of their own. A person will continue to perform a certain action because of the reward at the end of the action. An Actor receives a Grammy for outstanding performance. That actor will try to perform this action again in the next movie they are in. On the other hand, negative reinforcement (punishment) will elicit a response to not perform that behavior again. (Friedman Schustack, 2009). If you put your finger in an electric socket the electric shock will influence you not to perform this habit again. John B. Watson was instrumental in the development of the behavioral learning approach. Watson believed in the experimental method and if psychology were to be a science, then only the observable behavior was a reasonable matter of science (Friedman Schustack, 2009). He looked at obvious behaviors that could be learned and controlled by the therapist. During his experiments Watson used animals and not human subjects. He believed he could get the same results from animals that others did using humans. Traditional behaviorism identifies two basic types of conditioning. Classic conditioning is defined by the repeated exposure of an unconditioned stimulus that elicits an unconditioned response and a neutral stimulus. The developed neutral stimulus can develop the same response as the unconditioned stimulus. B. F. Skinner developed the more radical approach of Operant conditioning. Operant conditioning results when a behavior is followed by reinforcement or punishment (Burger, 2010). Social cognitive personality development has some similarity as behaviorism. Behavioral and Social learning theories consists of four characteristic: Behaviorism, Basic Principles of Conditioning, Social Learning theory, and Social-Cognitive Theory. Behavioral is regarded as â€Å"attitude change, language acquisition, psychotherapy, student-teacher interaction, problem solving, gender roles, and job satisfaction. † Social learning is regarded as â€Å"thoughts, morals, expectancies, and individual insights† (Burger, 2010). Social-Cognitive theory as described by Albert Bandura engages in thinking and symbolic learning from observation. Behaviorism holds that people are conditioned, or trained, to respond in certain ways by rewards and punishments. Bandura suggested that there must be a way that people can learn simply by watching others, thereby removing the need to learn everything by monotonous trial-and-error (Krapp, 2005). People learn by observing others, with the environment, behavior, and cognition all as the chief factors in influencing development. These three factors are not stagnant or self-sufficient; rather, they are all shared. According to social learning theory, modeling influences learning primarily through its informative functions. As the observers in our environment we retain a portion of the modeled behavior, which then serves as a blueprint for the behavior. This type of learning incorporates four components: attention, retention, motor, and motivational processes that help to understand why individuals imitate socially desirable behavior (Krapp, 2005). Habits are developed from childhood into adulthood. Good and bad habits are formed during this time based on behavior and social influences. In today’s society our bad habits are more noticeable than our good ones. We are always trying to correct someone from doing something we would not do or say, yet we do not understand why they behave the way they do. Some families develop household habits that last a lifetime and can be passed from child to child. These childhood habits are hard to break and require years of reconditioning. Some become part of your way of life. In my family one of the many habits I developed or inherited, was to eat eggs with jelly all over them. Yes that is right!! You mix the jelly in with the eggs and that is how they are eaten. My father ate his eggs that way, his father ate eggs the same way and so did my Great Grandfather. I have yet to break this habit. My father reinforced this habit by providing praise and allowing me to try different jellies on my eggs. The more he paid attention to this behavior the more I performed the act. He had no idea he was conditioning me to perform a certain action based on his praise/reward. Until I studied behaviorism I had no idea this was a form of conditioning. This was not something he taught me, this was a behavior I observed as part of my family environment. Once I tried the eggs with jelly, I like the taste and this became part of my habits when eating scrambled eggs. For my children I allow them to have free will and eat what they like and how they like it. My six year old likes ketchup on her broccoli. This is not learned from observation, this is just her. of his is a good example of behavior of the family that influenced one of my habits. While serving in the Military, I developed a social habit that is wide spread in the Army. Using acronyms is a large part of the military language. We use this as part of our social communication. If you do not know or understand the terminology you are not â€Å"Hooah† enough. Some may say that situation is FUBAR (Fouled up Beyond All Recognition). I contribute my behavior more to the social cognitive theories of observation. My behavior has been shaped from observing others around me and taking bits and pieces from each of them and incorporating those behaviors into my personality. To this day I am an observer of others behavior. Good or bad, I have the free will to make a determination on what parts I will use to become part of my personality. This is why I disagree with the behaviorism theorist. I have not received reward or punishment for my behavior. Good, bad, or indifferent, my personality has not been affected by treating me like a lab rat and performing behavior changing experiments on me. I believe some personalities do need operant conditioning, mine is just not one of them. For those personalities developed from socially unacceptable environments, some form of conditioning is necessary to develop a socially acceptable behavior. The first course of action is to take them out of the environment and allow them to see a more positive behavior. The saying goes you can take the child out f the country, but you cannot take the country out of the child (country can be substituted with any negative environment). I have worked hard to eat eggs the way it is socially accepted. In public I will eat the way it is expected for you to eat, but this differs from environment to environment. In Germany, boiled eggs are egg more served than scrambled. Thereby I adjust to the environment I am exposed to. At home I can eat the way I want to and enjoy my eggs and jelly. Some habits you just do not want to change. I enjoy the taste of a finely cooked, scrambled egg and grape jelly. How to cite Behavioral and Social/Cognitive Approaches to Forming Habits, Papers

Causes of Teenage Suicide Essay Example For Students

Causes of Teenage Suicide Essay Teenage suicide is one of the major problems in our society nowadays. Parents struggle to hold their children from a rash venture, but they have no idea that every child is an individual with overwhelming feelings, emotions, and thoughts. While there are plenty of argumentative and expository articles on the Internet with explanation and instruction concerning prevention of teen suicide, parents should find a way with their children, be calm and let their children understand that they can trust their parents. Outline1 Introduction: What is teen suicide?2 What are the causes and effects?3 Conclusion Introduction: What is teen suicide? The majority of people does not really know why teens end up falling back on suicide attempts. They know only the information presented by the media. According to mass media, suicide attempts are common among those teens who suffer depression, violence, abuse, any form of bullying and anxiety. However, if people turned to social sciences such as psychology, sociology or anthropology, they would understand that this problem lies deeper than they thought. Teen suicide has different meanings in different societies. People in our society usually think about suicide as the way to escape problems or as the only solution of all the problems that teens face in their adolescent years. But in other societies, as for example in Micronesia, the youth treats the suicide just the same as smoking or another way to express themselves. According to Gladwell, in Micronesia, teenagers like to experiment with the death just as our youngsters with smoking. Boys and girls in that areas think about suicide as some kind of game. They hang themselves or put their heads in a noose just to entertain themselves. Therefore, there is a risk that they will die from anoxaemia, just as our teens would die from lung cancer and other diseases. What are the causes and effects? From the point of view of anthropology, the youth of the First Nations and other indigenous peoples decide to commit suicide not only because of the depression or stress but because of drink or drug abuse, caused by the cultural and societal collapse. These people are no longer able to control their lives because of the immigrants and governmental laws. It decreases the sense of human worth and life in general and increases the rate of teen suicide. When it comes to sociology, the scientists are certain that the origins of the teen suicide among the First Nations youth are traced back to times when the government tried to assimilate indigenous people to Canadian and European ones. The government established facilities that were oriented on integration and assimilation of Aboriginal and non- Aboriginal people. Such a policy has changed and embittered lives of thousands of people causing irreparable harm for the next generations. It has created a sense of inferiority and deprivation of rights among the youth. Such a cultural collapse has evaluated the importance of lives for the indigenous people nowadays and increase the rate of teen suicide. Psychologists, as representatives of one of the social sciences, have their own explanation and understanding of the suicide.   The psychological state of the individual is the most important aspect when it comes to suicide. One of the causes why the Indigenous people choose death can be the fact that they are not able to satisfy their needs when it comes to accommodation, fitting in society and cultural respect. Moreover, they   don’t feel safe and secure in the environment they are living. The lack of understanding, love, relationships, and sense of belonging leads to an emotionally unstable state. Negative thoughts are overwhelming, the feeling of grief and uselessness prevails causing people to think that they lost their identity and death is the only solution. .ud922c3fe1ff797315467a8ea474911ce , .ud922c3fe1ff797315467a8ea474911ce .postImageUrl , .ud922c3fe1ff797315467a8ea474911ce .centered-text-area { min-height: 80px; position: relative; } .ud922c3fe1ff797315467a8ea474911ce , .ud922c3fe1ff797315467a8ea474911ce:hover , .ud922c3fe1ff797315467a8ea474911ce:visited , .ud922c3fe1ff797315467a8ea474911ce:active { border:0!important; } .ud922c3fe1ff797315467a8ea474911ce .clearfix:after { content: ""; display: table; clear: both; } .ud922c3fe1ff797315467a8ea474911ce { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud922c3fe1ff797315467a8ea474911ce:active , .ud922c3fe1ff797315467a8ea474911ce:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud922c3fe1ff797315467a8ea474911ce .centered-text-area { width: 100%; position: relative ; } .ud922c3fe1ff797315467a8ea474911ce .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud922c3fe1ff797315467a8ea474911ce .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud922c3fe1ff797315467a8ea474911ce .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud922c3fe1ff797315467a8ea474911ce:hover .ctaButton { background-color: #34495E!important; } .ud922c3fe1ff797315467a8ea474911ce .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud922c3fe1ff797315467a8ea474911ce .ud922c3fe1ff797315467a8ea474911ce-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud922c3fe1ff797315467a8ea474911ce:after { content: ""; display: block; clear: both; } READ: Evidence and Methodology in Darwin's Origin of the Species EssayIn his book, M. Gladwell stated that the suicide is committed under the influence of the contagious effect. In some countries, the suicide has become the way of showing your identity and individuality. Gladwell claims that as soon as the media started the publication of suicide stories, the suicide rate has rapidly increased. The research has shown that those under the action of contagious effect, died in the same way as the people by whose death they had been influenced. As Gladwell states, the publication of the suicide story where the victim died in car crash resulted in a growing number of such accidents. Conclusion As a conclusion, it is necessary to admit that teenage suicide is an irretrievable loss for families, friends, colleagues, colleges, and schools. The effects that close people suffer after such losses include depression, the feeling of regret and grief. They are no longer able to live lives to the fullest. To prevent such a loss, parents should always be kind to their children and treat them as individuals. Love, respect, care, understanding, and trust are the most important constituents of the upbringing of your child. Provide your children with the right insight of the world and point out the important values in life in order to set them on the right track.

Asians and Census 2000 essays

Asians and Census 2000 essays There are numerous reasons why full participation is in the Census 2000 is important to the Asian American and Pacific Islander communities. The estimated undercount of the Asian Pacific Islander community in 1990 was 2.3%. Because census data is the basis for almost all demographic information used by policy makers, educators, and community leaders, undercounted communities miss out on their fair share of federal funding for services, adequate governmental representation, and enforcement of civil rights laws that prevent discrimination. An undercount prevents government and other agencies from planning for and implementing culturally and linguistically appropriate services for the Asian Pacific Islander community. (U.S. Census Bureau) Unfortunately, the Asian Pacific Islander community is at risk for a high undercount in the upcoming census. Undercounts tend to be high in communities in which there are language barriers, resistance to outsiders, suspicion of government, disbelief of census confidentiality, non-traditional household living arrangements, irregular housing, large numbers of children, large proportions of renters, and among people or families who are highly mobile. (U.S. Census Bureau) One important reason for full participation by Asian American and Pacific Islander communities is the need for adequate governmental representation. Reapportionment occurs after every census, which is when political districts are reconfigured to reflect changes in the population. When Asian Americans and Pacific Islanders are not counted, they are not assigned the correct number of representatives. It is important that they have a voice in the government. There is a need for political empowerment among the Asian American and Pacific Islander communities, and that can happen only when there is accurate representation, which is the result of an accurate census count. Another important reason for the full participation of Asian...

The Objectives of Plagiarism and Censorship

The Objectives of Plagiarism and Censorship Hashtag: #SinCensuraVigilantes (Without Vigilant Censorship) The Objectives of Plagiarism and Censorship Censorship is commonly known as suppression of anything objectionable while plagiarism prevents stealing and offering other authors ideas as your own. Censorship is common in media, films, TV, books, the Internet, and so on because they are a powerful medium of communication that has the ability to influence millions of people. The power to engage in censorship is not limited to the government because private organizations and  individuals can be involved in censorship. Censorship can be voluntary undertaking such as self-censorship of your own work (authors, film directors, etc.). Not all people are happy with censorship as it restrictions often deprive people of facts, and suppress their freedom of expression. Censorship in the print media such as newspaper, books, etc. greatly reduces the quality of information they deliver. Since a morning newspaper with graphic images of casualties of a tragic car accident can greatly affect their families’ feelings, the reading public will only see the censored images of the  accident rather than the reality of driving too fast or being more concerned about safety. Similarly, censorship of a film depicting the abuses and discriminatory practices of government offices against a certain ethnic group will likely deliver nothing but entertainment rather than truth and policy change. Plagiarism, on the other hand, is normally strict on literary works as books, journals, and so on because they are academic papers that usually contained ideas acquired from years of painstaking research. Certainly, presenting these ideas as your own is fraud, depreciation of their hard work, and breach of their intellectual rights. Want to know more? Go here: The Limits of Academic Freedom Educational Field Trip Safety Issues The Scientific Basis for Defining Seasons Who and What Deserve Respect Torture Is Never Justified The act of plagiarism usually occurred when a person writing an essay, for example, write exactly the same words or sentence that the person read from the source without proper citation. It can also occur when the writer acknowledged the wrong author or used copyrighted images without permission. The Similarities of Plagiarism and Censorship Some people see plagiarism and censorship as two different things living in an entire world. Others see censorship as suppressors of obscenity and plagiarism as eliminators of literary thieves. However, there is more to them than meets the eye. That is if one would dare see them in right perspective. Censorship suppresses the publicity of immoral and offensive materials. In other words, it prevents people from getting any credit from something that is ethically and legally unacceptable. Similarly, censorship prevents people from presenting materials that will hurt the dignity of those involved. For example, a film entirely centered on women’s nudity, a video showing a young innocent boy abused, or an article containing provocative ideas about the superiority of one man’s color over the other definitely deserve censorship. The point here is the fact that censorship, similar to plagiarism, is actually dealing with and resolving problems the same way. This is because plagiarism also suppresses the publicity of immoral written material that does not only contain stolen ideas, with an author expecting to gain from another man’s pain but offensive to the cheated readers of these deceitful academic materials.

Critically assess the potential use of the marketing information Essay

Critically assess the potential use of the marketing information system (MIS) to help marketing managers understand and fulfill - Essay Example However the previous research studies suggest that following avenues of the firms’ decisions in relation to its market operations are typically addressed in modern-day MIS; (1) the background factors (2) the actual information processing behavior and (3) the role of information activities in shaping the firm’s competitive advantage. Therefore it is clear that MIS address all the avenues of decision making in marketing. Current study attempts to compile the characteristics of the information processing involved in making sound marketing decisions and the specific advantageous of using MIS. Steps involved in information processing which is aimed at formulating sound marketing decisions are illustrated and the performances of modern-day MIS are evaluated in terms of the advantageous and scope for development. Marketing is a well structured subject area which contains clear conceptual frameworks and a substantial amount of empirical case studies which utilize the subject th eory. It is defined as â€Å"a social and managerial process whereby individuals and groups obtain what they need and want through creating and exchanging products and value with others† (Kotler, and Armstrong, 2010). ... changes in market conditions and anticipating market competition from new domestic and international firms entering into market and intensifying competition from the existing firms (3) design reliable marketing plans, considering the advantages and disadvantages of alternatives marketing strategies (4) find effective solutions to specific problems such as what is the best approach for launching a new product and what are the suitable product promotion strategies and (5) improve the overall performance of the organization by better controlling, monitoring and implementing marketing strategies which in turn increase the efficiency and the effectiveness of firms’ marketing division (Churchill, 2001; & Leonidou, and Theodosiou, 2004). Basic characteristics of MIS 1) The Background Factors Incorporated in MIS The background factors which can influence the marketing decisions include characteristics of the firm and the manager, government policies and consumer preferences and income levels. Previous researches which are aimed at exploring the background factors indicate that organizations with innovative cultures are more likely to seek information and appreciate its usefulness in making marketing decisions. Experience, level of education, cognitive styles and decision-making levels determine the manager’s information-processing style. Organizations which are not hierarchical in structure and decision making process is rather decentralized obtain more advantageous from MIS compared to those organizations which are highly formalized (Menon & Varadarajan, 1992). Moreover, the volatility in the external marketing environment also increases the degree of usefulness of MIS to marketing managers. Market volatility increases the supply and demand uncertainty which in turn

Women and poverty Essay Example | Topics and Well Written Essays - 1000 words

Women and poverty - Essay Example With the poverty levels in women growing at a faster rate than those of men, different authors have sought to look for alternatives to solving the problem. With the governmental agencies seemingly relaxing on addressing the issue, it remains the efforts of researchers to provide the solution to the problem. In Canada, Burkhauser and Sabia seek to offer solutions with the intention of minimizing the high poverty levels among women by bridging the wage gap between men and women. They observe that only men occupy big jobs in organizations, with women assuming the role of support personnel. Although more women now have jobs, the fact that they do not occupy large positions in these firms contributes to the wide poverty gap. According to them, the best way of solving the problem of high poverty levels in women is through increasing the minimum wage levels among women in the society. They argue that despite the fact that people work in big organizations, they have low incomes, which when p assed over to the family, creates a vicious cycle of poverty in the society. The journal addresses on the means available to reduce the level of poverty. While other articles propose on the means of reducing the level of poverty among women in the society, this particular article offers guidelines on how raising the minimum wage levels for women as the most significant solution to the problem. The government, while addressing the problem of poverty in Canada, have even influenced the politics of neoliberalism in Canada....

Complexity of Poetry Essay Example for Free

Complexity of Poetry Essay Poetry is a way for the reader to openly interpret a poem in almost any way they see fit. Because there is so much freedom of interpretation with poetry, there leaves a lot of room for discussion and opposition. Billy Collin’s poem, â€Å"Introduction to Poetry†, breaks down the basic ways for interpreting and understanding a poem. In summary, he explains that the reader cannot focus on trying to figure out one specific meaning of a poem, but instead, try to piece together small parts to understand a deeper meaning. Collin’s rules on how to interpret a poem can be applied to Hughes’s poem about a young student writing a poem for homework. Instead of looking at Hughes’s poem as a whole, the reader can better understand it by breaking it down and figuring out why each line is important and how it ties together with the poem as a whole. Understanding Collins rules to interpret a poem, help the reader decipher Hughes poem on a deeper, more academic level. Langston Hughes’s poem explains how a black, twenty two year old man and the rest of his white classmates are given an assignment to write a paper. The narrator, who is also the student, explains his thoughts about the assignment and how him being the only colored one in his class might be reflected on his grade on the assignment. At the beginning of the poem, he explains how he has to get to class everyday by traveling across some of the â€Å"better† parts of town. The student goes on to explain how even though he is colored, he likes the same things and has the same wants as everyone else. He states that he is no different than the rest of his class and that he too has knowledge to share. By stating this, the student is expressing to the reader how he thinks him and the instructor are equal. In the last few lines the student writes, â€Å"As I learn from you, / I guess you learn from me† (37-38). This explains how even though their skin color and age is different they are still able to learn from each other. The student has a somewhat optimistic and confident tone throughout the poem. He is aware of his capabilities and knows that he can be just as successful as anyone else. Billy Collins â€Å"Introduction to Poetry† explains how whenever people analyze a poem they do not try to find the true message of it. By writing, â€Å"But all they want to do / is tie the poem to a chair with rope / and torture a confession out of it,† explains how the majority of people are lazy and want everything handed to them effortlessly (12-14). This last stanza explains how some people look at poems from one point of view and expect the meaning of the poem to be written out for them. The author is stating that people should look at the poem from different angles just as one would look at the world from a color slide. He tries to explain to the reader that if one were to interpret the poem from a whole new approach, then they could find a deeper meaning than just the surface meaning. After reading Collins â€Å"Introduction to Poetry†, the reader should have a better sense of how to interpret Hughes’s poem. Throughout the first part of Hughes’s poem the reader may think all of the characters background information including his address, age, and hometown is pointless. After reading an entire stanza about this â€Å"pointless† information the reader may try to stop understanding the poem before they even finish it. If the reader uses Collins instructions about analyzing a poem, they may find that all of this â€Å"pointless† information is actually important and helps contribute to the characters feelings of insecurity. Collins poem explains that not all poems have one specific answer or meaning the writer is trying to get across. Keeping this idea in mind, the reader may realize that Hughes’s poem, in fact, does not state an answer or solution to the characters mixed feelings. Although both of these poems leave room the readers own special interpretation, there is a basic meaning and idea to each one. Both of these poems fit well together because Collin’s thoughts and ideas can be directly applied when reading Hughes’s poem. The poems are an effective example of how even though a poem may seem short and simple, there is usually a deeper and greater meaning beneath the surface.

Blaming External Pressure for the Tragic Decline of Tess in Tess of the

Blaming External Pressure for the Tragic Decline of Tess in Tess of the D'Urbervilles From the beginning of the novel 'Tess of the d'Urbervilles' by Thomas Hardy, it is clear that the main character, Tess, is not going to have an easy life. She is deliberately targeted by cruel "Immortals" as their sadistic plaything. This is symbolized during the club dance, where Tess is "one of the white company" but is the only one to have a bright "red ribbon" in her hair. The mark of blood is on her from the start. Whilst Tess is going to market she accidentally kills the family's horse. Her own guilt for this accidental death is the first stage in a long series of incidents leading to Tess's tragic death at the end of the novel. Social and environmental pressures rank high on the list of causes of Tess's tragedy. In the late 19th century there were many changes taking place in rural England. The advances achieved as a result of the Industrial Revolution meant that even in the countryside farming was becoming mechanized and there were fewer manual labour jobs for the simple peasant people to do. This meant many people had to leave their town where they had spent most of their lives to go and find work. So, for example, the Durbeyfields' departing from Marlott after the death of "Sir John", was only part of a greater rural upheaval. Tess's search for work to make up for the loss of her family's horse led her to the sinister and blatantly predatory Alec d'Urberville who she initially thought was a relative. The sexual double standards typical of late Victorian society were also clear at this point. Females who sinned paid a much higher social price for their mistakes. But Tess did not want to sin - she was pres... ... reach Stonehenge it is obvious that Tess's life of never ending pain and suffering will soon be over. Stonehenge is significant as it was a place for sacrifices in pagan times. The cruel "Immortals" have at last brought Tess to the place of sacrifice - they will soon end their sadistic "sport". I conclude that Hardy wrote this book to show that "individuals have no control over their lives, but are at the mercy of impersonal and inexorable forces", as stated in the resource notes to the Cambridge edition of the novel. From the beginning Tess's destiny was mapped out. She was born to suffer and eventually die. Tess was in the end a victim of the circumstances of late Victorian rural society, with all its cruel discrimination against erring females, but even more so of cruel supernatural forces who had marked her out as their victim from the beginning.

Mathematical in India Past, Present, Future

Mathematics in India Past, Present and Future What is mathematics? â€Å"mathematics is a science of space, numbers and quantity† Past: Indian mathematics emerged in the Indian subcontinent from 1200 BC until the end of the 18th century. In the classical period of Indian mathematics (400 AD to 1200 AD), important contributions were made by scholars like Aryabhata, Brahmagupta, and Bhaskara II. The decimal number system in use today was first recorded in Indian mathematics.Indian mathematicians made early contributions to the study of the concept of zero as a number, negative numbers, arithmaticm and algebra. In addition, trigonometry was further advanced in India, and, in particular, the modern definitions of sine and cosine were developed there. These mathematical concepts were transmitted to the Middle East, China, and Europe and led to further developments that now form the foundations of many areas of mathematics. Present: 20th century The 20th century saw mathematics beco me a mojor profession.Every year, thousands of new Ph. D. s in mathematics are awarded, and jobs are availablein teaching, research and industry. Mathematical collaborations of unprecedented size and scope took place in India. One of the more colorful figures in 20th – century mathematics was Srinivasa Aiyangar Ramanujan (1887-1920), an Indian autodidact who conjectured or proved over 3000 theorems, including properties of highly composite nimbers, the partition function and its asymptotic, and mock theta functions.He also made major investigations in the areas of gamma functions, modular forms, divergent series, hyper geometric series and prime number theory. 21st century In 1980, Shakuntala Devi gave the product of two, thirteen digit nimbers within 28 seconds; many countries have invited her to demonstrate her extraordinary talent. In Dallas she competed with a computer with a computer to see who give the cube root of 188138517 faster, she won. At university of USA she was asked to give the 23rd root, she answered in 50 seconds. The answer is 546372891.It took a UNIVAC 1108 computer, full one minute (10 seconds more) to confirm that she was right after it was fed with 13000 instructions. Now she is known to be Human computer. FUTURE: There are many observable trends in mathematics, the most notable being that the subject is growing ever larger, computers are ever more important and powerful, the application of mathematics to bioinformatics is rapidly expanding, the volume of data to be analyzed being produced by science and industry, facilitated by computers, is explosively expanding.The field of mathematics has become so large that it has become impossible to have an overview of all relevant mathematics. A formalized library should enable the search for relevant results. When designing new high-tech systems, like software for an automatic pilot super computer etc. , one uses complicated mathematical models. Indian mathematician, engineers and scient ist ar eone of the top leading in this trend. CONCLUSION: Mathematics is a science of all sciences and art of all arts. Without the proper foundation of mathematics, any science or subject will be a failure, Mathematics is a creation of human mind, concerned cheifly with the ideas, processes and reasoning the modern world of technology, tools such as computer requires the basic mathematics and calculations. Matehmatics is the instrument of education found to be in conformity with the human mind. If we sincerely give our time in the subject of mathematics, we can also come up with innovative ideas and thoughts that can shape the entire universe as our ancestors do in past. We look forward to what the future will bring.

A Comparative Analysis: Juvenile and Adult Courts

For many years, people have believed that the juvenile justice system was meant to serve as a way to protect the community. Juveniles who commit crimes are different from adults because many do not understand the complexity of the crime committed. In order to respond to these differences, many states have established a way to treat these adolescents through juvenile courts and youth-based recovery systems. While most states recognize that juveniles who commit crimes should not be treated as an adult there are still some that are skeptic that the juvenile justice system works.The juvenile justice system began in 1899, in Chicago, Illinois where the nation’s first juvenile system was established. In the beginning the system was informal and often times it was nothing more than a conversation between the juvenile and a judge (Juvenile Law Center, 2013). Over the years the system has changed significantly where juvenile courts have created a probation system which provided a diffe rent method to provide juveniles with guidance, supervision, and education.By the 1920s all but two states had followed the suit but it was not until the 1960s where the juvenile justice system was given several of the same legal rights as the adult court. There are many differences between the juvenile and adult criminal systems but they also share their similarities. While their differences vary depending on the state, the similarities can be said to be our natural born rights. One of the main similarities is the right to an attorney (LaMance, 2013). The defendant has the choice of either choosing a public defender to represent them or to hire a paid attorney.Both courts not only give their defendants the right to cross-examine witnesses but also the privilege against self-incrimination. The prosecution must also provide proof beyond a reasonable doubt before either of the two can be charged and convicted (LaMance, 2013). The two also share the right to receive a transcript of the proceedings and the rights to have an appellate court review the lower court’s decision. One of the main differences is the overall goal for both courts.While the goal for the adult court is to  punish and convict, the juvenile justice system prefers the method of rehabilitation and reformation, thus giving the juvenile a chance to become a productive citizen (LaMance, 2013). Unlike adults, juveniles do not have the right to a public trial and an adjudication hearing is required in order for the judge to determine if the minor is a delinquent. If considered a delinquent, the court then decides which steps should be taken where the best interest for the juvenile is taken into consideration.The juvenile court is still more informal than that of the adult court (LaMance, 2013). An example of their informality is the rule for admissibility of evidence which is much more lenient in the juvenile court. Lastly juveniles are usually not prosecuted for the delinquent acts that he o r she has committed. However depending on the severity of the crime and state laws, juveniles can be transferred and tried in the adult system (LaMance, 2013). The adjudication process in which juveniles are transferred to the adult system varies by state.While some states enable the transfer of certain juveniles with a waiver, depending on their age and offense criteria, other states consider the juvenile to be an â€Å"automatic adult† (OJJDP National Report Series: Juvenile in Court, 2013). Although all states allow juveniles to be tried as adults in criminal court there are a few circumstances that follow. All states except for Nebraska, New Mexico, and New York provide a judicial waiver where the juvenile court judge has the authority to waive juvenile court jurisdiction and transfer cases to the adult court.Other states have a concurrent jurisdiction where the original jurisdiction for certain cases is shared by both juvenile and adult courts. The discretion under the c oncurrent jurisdiction is left to the prosecutor. Statutory exclusion is the legislative method, which mandates juvenile prosecution in adult court. Youths charged with certain crimes can be placed in the adult system automatically, thus removing any kind of decision making process from judges or prosecutors (OJJDP National Report Series: Juvenile in Court, 2013).In recent years states have significantly expanded legislation for allowing the use of judicial waivers. This trend has increased the number of juveniles incarcerated throughout the United States and has expectations to rise. Having a juvenile treated as an adult gives them the possibility of life or death sentences and incarceration in state of federal prisons which can have a tremendous impact on the life and future of a juvenile (Find Law, 2013).Although it may be served as a deterrent to some, sending juveniles directly to the adult criminal court gives the juvenile the impression that there is no room for rehabilitatio n or second chances, thus paving the way for a life of crime for others. Since the late 1970s, critics of the juvenile justice courts have pursued to abolish this system with the assumption that this system has failed its purpose, to rehabilitate juveniles (LaMance, 2013). Abolishing juvenile courts holds ramifications for not only juveniles but also the community.Eliminating these courts would mean that all juveniles, no matter the age or crime, would be treated as an adult. Many jobs and careers would be lost for those who have committed their lives to making a difference in the juvenile justice system, jobs such as social workers, juvenile detention guards, and juvenile probation officers. An argument can be made to abolish this system but the idea that young offenders whom are not mentally competent to understand their behavior still stands (LaMance, 2013).Therefore juveniles should be handled in a different court system. The juvenile justice system has grown and changed substan tially since 1899. The justifications of the juvenile court system are that youth are developmentally different from adults and should not be treated the same. Having a system that focuses on the needs of children, who are maturing into adulthood, not only gives the community hope but also gives the juvenile a real chance to rehabilitation and recovery.

Mollusk Facts

Mollusk Facts Mollusks may be the most difficult animal group  for the average person to wrap their arms around: this family of  invertebrates  includes creatures as widely divergent in appearance and behavior as snails,  clams, and cuttlefish. Fast Facts: Mollusks Scientific Name: Mollusca (Caudofoveates, Solanogastres, Chitons, Monoplacophorans, Scaphopods, Bivalves, Gastropods, Cephalopods)Common Name: Mollusks or molluscsBasic Animal Group: Invertebrate  Ã‚  Size: Microscopic to 45 feet in lengthWeight: Up to 1,650 poundsLifespan: Hours to centuries- the oldest is known to have lived over 500 yearsDiet:  Mostly herbivore, except for cephalopods who are omnivoresHabitat: Terrestrial and aquatic habitats on every continent and ocean in the worldConservation Status: Several species are threatened or endangered; one is extinct Description Any group that embraces  squids, clams, and slugs present a challenge when it comes to formulating a general description. There are only three characteristics shared by all living mollusks: the presence of a mantle (the rear covering of the body) that secretes calcareous (e.g., calcium-containing) structures; the genitals and anus opening into the mantle cavity; and paired nerve cords. If youre willing to make some exceptions, most mollusks can also be characterized by their broad, muscular feet which correspond to the tentacles of cephalopods, and their shells (if you exclude cephalopods, some gastropods, and the most primitive mollusks). One type of mollusk, the aplacophorans, are cylindrical worms with neither shell nor foot. Getty Images Habitat Most mollusks are marine animals that live in habitats from shallow coastal areas to deep waters. Most stay within the sediments at the bottom of water bodies, although a few- such as cephalopods- are free swimming. Species There are eight different broad categories of mollusks on our planet. Caudofoveates  are small, deep-sea mollusks that burrow into soft bottom sediments. These worm-like animals lack the shells and muscular feet characteristic of other mollusks, and their bodies are covered with scale-like, calcareous spicules.Solanogastres, like caudofoveata, are worm-like mollusks that lack shells. These small, ocean-dwelling animals are mostly blind, and either flattened or cylindrical.Chitons, also known as polyplacophorans, are flat, slug-like mollusks with calcareous plates covering the upper surfaces of their bodies; they live in intertidal waters along rocky coastlines worldwide.Monoplacophorans are deep-sea mollusks equipped with cap-like shells.  They were long believed to be extinct, but in 1952, zoologists discovered a handful of living species.Tusk shells, also known as scaphopods,  have long, cylindrical shells with tentacles extending from one end, which these mollusks use to rope in  prey from the surrounding water.Bivalves are characterized by their hinged shells and live in both marine and freshwater habitats. These mollusks have no heads, and their bodies consist entirely  of a wedge-shaped foot. Gastropods  are  the most diverse family of mollusks,  including over 60,000 species of  snails and slugs that live in marine, freshwater, and terrestrial habitats.  Cephalopods, the most advanced mollusks, include  octopuses, squids, cuttlefish, and nautiluses. Most of the members of this group either lack shells, or have small internal shells. A tusk shell. Getty Images Gastropods or Bivalves Of the roughly 100,000 known mollusk species, about 70,000 are gastropods, and 20,000 are bivalves or 90 percent of the total. It is from these two families that most people derive their general perception of mollusks as small, slimy creatures equipped with calcareous shells. While the snails and slugs of the gastropod family are eaten the world over (including as escargot in a French restaurant), bivalves are more important as a human food source, including clams, mussels, oysters, and other undersea delicacies. The largest bivalve is the giant clam (Tridacna gigas), which reaches a length of four feet and weighs 500 pounds. The oldest mollusk is a bivalve, the ocean quahog (Arctica islandica), native to the northern Atlantic and known to live at least 500 years; it is also the oldest known animal. Bright yellow banana slug. Alice Cahill/Getty Images Octopuses, Squids, and Cuttlefish Gastropods and bivalves may be the most common mollusks, but cephalopods (the family that includes octopuses, squids, and cuttlefish) are by far the most advanced. These marine invertebrates have astonishingly complex nervous systems, which allows them to engage in elaborate camouflage and even display problem-solving behavior- for example, octopuses have been known to escape from their tanks in laboratories, squish along the cold floor, and climb up into another tank containing tasty bivalves. If human beings ever go extinct, it may well be the distant, intelligent descendants of octopuses that wind up ruling the earth- or at least the oceans! The largest mollusk in the world is a cephalopod, the colossal squid (Mesonychoteuthis hamiltoni), known to grow to between 39 and 45 feet and weigh up to 1,650 pounds.   548901005677/Getty Images Diet With the exception of cephalopods, mollusks are by and large gentle vegetarians. Terrestrial gastropods like snails and slugs eat plants, fungi, and algae, while the vast majority of marine mollusks (including bivalves and other ocean-dwelling species) subsist on plant matter dissolved in the water, which they ingest by filter feeding. The most advanced cephalopod mollusks- octopuses, squids, and cuttlefish- feast on everything from fish to crabs to their fellow invertebrates; octopuses, in particular, have gruesome table manners, injecting their soft-bodied prey with venom or drilling holes in the shells of bivalves and sucking out their tasty contents. Behavior The nervous systems of invertebrates in general (and mollusks in particular) are very different from those of vertebrate animals like fish, birds, and mammals. Some mollusks, like tusk shells and bivalves, possess clusters of neurons (called ganglions) rather than true brains, while the brains of more advanced mollusks like cephalopods and gastropods are wrapped around their esophagi rather than isolated in hard skulls. Even more weirdly, most of the neurons of an octopus are located not in its brains, but in its arms, which can function autonomously even when separated from its body. The mouth of a limpet. Getty Images Reproduction and Offspring Mollusks generally reproduce sexually, although some (slugs and snails) are hermaphrodites, they still must mate to fertilize their eggs. Eggs are laid singly or in groups within jelly masses or leathery capsules. The eggs hatch into veliger larva- small, free-swimming larvae- and metamorphose into different stages, depending on the species.   Evolutionary History Because modern mollusks vary so widely in anatomy and behavior, sorting out their exact evolutionary relationships is a major challenge. In order to simplify matters, naturalists have proposed a hypothetical ancestral mollusk that displays most, if not all, of the characteristics of modern mollusks, including a shell, a muscular foot, and tentacles, among other things. We dont have any fossil evidence that this particular animal ever existed; the most any expert will venture is that mollusks descended hundreds of millions of years ago from tiny marine invertebrates known as lophotrochozoans (and even that is a matter of dispute). Extinct Fossil Families Examining the fossil evidence, paleontologists have established the existence of two now-extinct classes of mollusk. Rostroconchians lived in the worlds oceans from about 530 to 250 million years ago, and seem to have been ancestral to modern bivalves; helcionelloidans lived from about 530 to 410 million years ago, and shared many characteristics with modern gastropods. Somewhat surprisingly, cephalopods have existed on earth ever since the Cambrian period; paleontologists have identified over two dozen (much smaller and much less intelligent) genera that plied the worlds oceans over 500 million years ago. Mollusks and Humans Wayne Barrett Anne MacKay / Getty Images Over and above their historical importance as a food source- especially in the far east and the Mediterranean- mollusks have contributed in numerous ways to human civilization. The shells of cowries (a type of small gastropod) were used as money by Native Americans, and the pearls that grow in oysters, as the result of irritation by sand grains, have been treasured since time immemorial. Another type of gastropod, the murex, was cultured by the  ancient Greeks for its  dye, known as imperial purple, and the cloaks of some rulers were woven from long threads secreted by the bivalve species Pinna nobilis. Conservation Status There are over 8,600 species listed in the ICUN, of which 161 are considered Critically Endangered, 140 are Endangered, 86 are Vulnerable, and 57 are Near Threatened. One, the Ohridohauffenia drimica was last seen in 1983 in springs feeding the River Drim in Macedonia, Greece and was listed as extinct in 1996. Additional surveys have failed to find it again. Threats The vast majority of mollusks live in the deep ocean and are relatively safe from the  destruction of their habitat and depredation by humans, but thats not the case for freshwater mollusks (i.e., those that live in lakes and rivers) and terrestrial (land-dwelling) species. Perhaps not surprisingly from the perspective of human gardeners, snails and slugs are most vulnerable to extinction today, as they are systematically eradicated by agriculture concerns and picked off by invasive species carelessly introduced into their habitats. Just imagine how easily the average house cat, used to picking off skittering mice, can devastate a near-motionless colony of snails. Lakes and rivers are also prone to the introduction of invasive species, particularly mollusks which travel attached to international seagoing ships. Sources Sturm, Charles F., Timothy A.

Mollusk Facts Mollusks (Mollusca) is a taxonomic phylum that contains a diverse array of organisms, including snails, sea slugs, octopuses, squid, and bivalves such as clams, mussels, and oysters. Between 50,000 and 200,000 species are estimated to belong to this phylum. Imagine the obvious differences between an octopus and a clam, and youll get an idea of the diversity among mollusks. Fast Facts: Mollusks Scientific Name: Mollusca: Gastropoda, Bivalvia, Cephalopoda, Monoplacophora, Scaphopoda, Aplacophora, PolyplacophoraCommon Names: Snails, sea slugs, octopuses, squid, and bivalvesBasic Animal Group: InvertebrateSize: Varies from 0.04 inch (solenogasters and gastropods) to 4 feet (giant clam)  Lifespan: 3 years to over 500Diet:  Carnivore or herbivoreHabitat: Oceans and coastal waterways worldwidePopulation: UnknownConservation Status: Most are classified as Least Concern; mollusks make up nearly one-fourth of all marine animals on Earth.   Description Mollusks have a shell and soft body and usually have a distinguishable head and foot region. Some may have a hard covering, or exoskeleton. Mollusks also have a heart that pumps blood through their blood vessels, digestive system, and a nervous system. In addition to a shell, most mollusks have a muscular foot for creeping or burrowing, and some have a head with sense organs. Their soft body includes lungs or gills for breathing and digestive and reproductive parts. These are surrounded by a skin-like organ called the mantle. Mollusks also have bilateral symmetry- one side is a mirror image of the other- and can have one or two shells. Their organs are in a fluid-filled cavity; indeed, the very word mollusk in Latin means soft. The upper body, or the mantle, is a thin, muscular sheet that covers the internal organs. Most mollusks, particularly those with shells, also have gills in the central part of their body cavity. Despite looking fragile, mollusk shells are quite hard. Scientists are even studying nacre, a material found in mollusk shells, to develop materials that are stronger and lighter than steel. Puneet Vikram Singh, Nature and Concept photographer/Getty Images Habitat and Distribution Mollusks- snails, sea slugs, octopuses, squid, and bivalves- are found in habitats ranging from freshwater lakes and rivers to shallow coastal waters to the deepest parts of the oceans, worldwide. Most live in the bottom sediments, though cephalopods are primarily free-swimming species; some snails and clams are terrestrial. Species Mollusks belong to the kingdom Animalia and there are tens of thousands of invertebrates that fit into the Mollusca phylum. New ones are still being discovered, and researchers continue to modify the number and grouping classifications. One common schema used by researchers includes seven classes: Gastropoda (snails and slugs)  Bivalvia (clams, scallops, oysters, mussels)  Cephalopoda (squid, octopi, nautilus)Monoplacophora (limpets)  Scaphopoda (tusk shells)  Aplacophora (shell-less, worm-like animals)  Polyplacophora (chitons)  Ã‚   Diet and Behavior Many mollusks feed using a radula, essentially a series of teeth on a cartilage base. The radula can be used for complex tasks, from grazing on marine algae or drilling a hole in another animals shell. The radula scrapes tiny plants and animals off rocks or tears food into chunks. The adoption of different feeding habits appears to have had a major influence on molluscan evolution, according to the University of California Museum of Paleontology: The change from grazing to other forms of food acquisition is one of the major features in the radiation of the group. Based on our current understanding of relationships, the earliest mollusks grazed on encrusting animals and detritus. Since mollusks are such a wide-ranging phylum, its helpful to look at how one of the organisms that belong to this group feeds and how it captures its prey. Consider the deadly blue-ringed octopus. This mollusk hunts small crabs and shrimp during the day, but it will eat bivalves and small fish if it can catch them. The octopus pounces upon its prey, using its tentacles to pull its catch toward its mouth. Then, its beak pierces the crustaceans exoskeleton and delivers the paralyzing venom. The venom is produced by bacteria in octopus saliva, a combination of tetrodotoxin, histamine, taurine, octopamine, acetylcholine, and dopamine. Once the prey is immobilized, this mollusk uses its beak to tear off chunks of the animal to eat. The saliva also contains enzymes that partially digest flesh, so that the octopus can suck it out of the shell. The blue-ringed octopus is immune to its own venom. Reproduction and Offspring Some mollusks have separate genders, with males and females represented in the species. Others are hermaphroditic, which means they have both male and female reproductive organs. The mollusk life cycle varies greatly among different classes of mollusks and among species within classifications. Squids reproduce sexually: The females lay fertilized eggs in the water which hatch into larvae and then develop on their own. Octopuses do the same, except the females carry the eggs with her until they hatch. Clams, mussels, and oysters produce larvae that drop through the sea water and attach to a host to grow to maturity on. The hosts are usually fish, but oysters prefer the shell of an adult oyster. Land snails are hermaphrodites that mate and both partners produce fertilized eggs. The eggs are deposited in the soil; they hatch with a shell but most consume calcium to make it harden.   Mollusks and Humans The primary use that humans have for mollusks and the rest of ocean-living animals is their ability to filter large quantities of water, up to 10 gallons each. Mollusks are also important to humans as a food source- especially in the Far East and the Mediterranean- and have contributed in numerous ways to human civilization. The shells of cowries (a type of small mollusk that belongs to the gastropod family) were used as money by Native Americans, and the pearls that grow in oysters, as the result of irritation by sand grains, have been treasured for centuries. Another type of mollusk, the murex, was cultured by the  ancient Greeks for its  dye, known as imperial purple, and the cloaks of some rulers were woven from long threads secreted by the bivalve species (twin-shelled mollusks)  called Pinna nobilis. Culturing Tahitian pearls. CampPhoto/Getty Images Conservation Status Over 8,600 molluscs are listed in the IUCN Red List, most classified as Least Concern or Data Deficient, although many are threatened or endangered. The phylum represents nearly one-fourth of all the species on the planet. Threats Increasing levels of carbon dioxide are raising the pH level of the worlds oceans, which in turn, increases the acidity of these bodies of water. This greatly weakens mollusks otherwise strong shells and even makes it difficult for them to produce shells in the first place, threatening their survival. If mollusks begin to die out in mass, then fish and other animals that feed off of them may suffer. Northeastern University marine biologist Brian Helmuth gives the example of the common mussel, a member of the family of bivalve mollusks. In addition to the problem of increased acidity in the oceans, which, as noted, makes it harder for these mollusks to produce shells, the increasing temperatures of the oceans and even the sand and air on the surrounding beaches can mean a death sentence for mussels. â€Å"You are sitting there in the blazing sun, you’re not going to be able to move,† Helmuth says. â€Å"You can’t escape the heat, you can’t escape the sun, you can’t go into a crevice like ... a crab.† Mussels can literally start to cook on the rocks if they get too hot. Helmuth adds that global warming is shrinking the habitat in which mussels and other mollusks can live. And since mollusks are such an integral part of the food chain, that could eventually affect many other animals that depend on them for sustenance. Sources Beeler, Carolyn.

Teacher-Student Physical Distance Essay Example | Topics and Well Written Essays - 1750 words

Teacher-Student Physical Distance - Essay Example An art classroom is much more spatial than a normal classroom. The walls of classrooms were usually in light colors, with windows to allow enough sunlight. The posters on the walls were made of attractive colors and were arranged in a manner that is pleasant to look upon. Yes, there were differences, but there were also similarities. So I wondered, what were the reasons that classroom set-up was arranged in a particular manner? Does it influence the students’ learning? How? In particular, is the distance between the instructor and the student important? How does it affect the learning of the students? When the reasons for these set-ups are understood, then more individuals will support it – especially if it means learning efficiency. The mentors will employ this knowledge seeing that this will aid them in their endeavors to pass on knowledge to their students. Learners will also appreciate this, knowing that this will aid in them in gaining knowledge – the primar y reason why they study. LITERATURE REVIEW It has been well documented in literature that human emotions play a significant role in the way we live. We experience emotions in all of our activities, making these emotions sometimes control the activities that we engage in (Shan 142). As Shan (142) have said, â€Å"pleasant emotional experience can contribute to active and positive imitation and repetition, accompanied by pleasure, satisfaction and love etc., while the unpleasant one can cause people to behave negatively, leading to anger, complaints, hate, etc.† Since learning is also an activity that we do, emotions are therefore also important in the learning process. Classroom instruction is a communication process between the teacher and the students. Since emotions are involved here, the instructor’s emotions will affect the students just as the students’ will affect the instructor (Shan, 143). Astleitner (128) argued that influencing emotions during classroo m instruction is important as this will affect the learning of the students. The Fear Envy Anger Sympathy Pleasure or FEASP Theory is an approach that integrates emotions into classroom instruction (Astleitner 128; Astleitner, Hurek and Sztejnberg 63) saying that positive feelings (sympathy and pleasure) should be cultivated in the instructional design and conversely, avoid the negative emotions (fear, envy, anger). When Simon A. Lei (128) reviewed the literature about the effects of the physical design of a classroom to the learning of the students, he found a similar basic foundation. Though students learn in various ways, what remained the same was the fact that classrooms must be designed in such a way that positive feelings should be cultivated to empower both educators and learners. Then the various ways that students learn in the classroom will be facilitated. Seven physical attributes of a classroom that have a profound impact to student learning were identified by Lei (128- 129). First was the size of a room which could be small or large depending on the number of students on the class. Second was the furniture arrangement which could either be flexible or attached to the floor. Third was technology system arrangement in the classroom; if a modern technology was available there and where it was located. Fourth was lighting in the room; the intensity of light, its source, and if a multiple light settings were present. Fifth was the

HR Practices - Essay Example While the behaviors outlines the HR professional’s attributes that one needs to develop and use through the work, the bands concentrate on describing the transition from one level of professional competence to another, measuring up the contributions and outcomes of the strategic steps used in each level. The map has two core areas which represent the two core professional areas of HR practices. The first one is named, ‘Insights strategies and solutions’ and is placed at the innermost core, while the second one is the outer core of the map and is named, ‘Leading HR’. ‘Insights strategies and solutions’ concentrates on enriching HR practices by providing all the tools and facts that need to be maintained in the development of a viable HR strategy, solutions to address all issues within the strategy, and insights from external and personal experiences to help reach the right combination of strategy, outcome and solutions. These include measuring up employee and customer profiles and prioritizing political, social, and technical relationships and decisions. The ‘Leading HR’ segment concentrates on qualities required to achieve excellent personal and team leading capabilities. The section also identifies the required solutions to delive r performance and add value to HR teams led and manage HR budgets. For both the core professional areas, the Performance and Rewards band can be tested out at band four. For a senior HR professional, the use of performance and rewards strategies would lead to better performance by the junior members of the HR team. The ‘Insights strategies and solutions’ and ‘Leading HR bands are well addressed by senior HR professionals when they use a performance and rewards approach in determining each step. Attracting and retaining a diverse workforce is all about giving your organization the benefit of multi-background employees who are competent enough to understand the dynamics of different markets.

Quality improvement program Essay Example | Topics and Well Written Essays - 500 words

Quality improvement program - Essay Example Normally, not all outpatient clinics are required to pass the Joint Commission Requirements for quality; nevertheless, VSA is necessitated to. Since the time of its launch where it first developed its quality control program until today, the Virginia Surgical Associates remains serious about meeting all Joint Commission Requirements such as the Environment of Care, which pertains to how safe, functional and efficient the environment for patients, staff, and other individuals is in the organization; Infection Prevention and Control: how well the clinic is able to lower down the risk of surgical patients acquiring infection; Rights of Individual, which evaluates the establishment of informed consent, participation in decision-making of patients, and services to respect patient’s rights, etc. (Joint Commission, 2014). But despite VSA’s strong commitment to maximize the quality of its services, it is still bending more attention to quality improvement that includes examinin g rates and complications and lab equipments such as ACT machine that s a point-of-care, blood clotting test used to monitor anticoagulation (Philip et al., 2008). The Virginia Surgical Associates is constantly developing its Quality Improvement Program to address these requisites. While healthcare quality measurement is developing, there are more things to take care of. The complicated environment of the healthcare industry makes quality program monitoring and implementation a lot more difficult. It is important that in revising and monitoring quality program implementation, new quality measures are developed in order to address rising issues within the healthcare industry. 1. Type of Care and Patient Engagement. The quality of the healthcare services can be monitored by the patient engagement with respect to the types of care being administered (Mainz,

Effect of the Local Environment on Bees

Effect of the Local Environment on Bees Local Environment Europe The effect of the local environment on bee abundance and diversity in regions throughout Europe. Bees have an important ecological role; they are insect pollinators providing a crucial service. Without insect pollination human diet would be very different to how we know it now. Declines in pollinators have been reported and by attempting to understand the how the local environment affects bee abundance and diversity it may be possible to prevent any further decline. Samples were collected at six sites across Europe in each site there was a disturbed landscape and a natural landscape and within each of these a hot and a cold area. Samples were collected, pinned and identified to genera and the Halictus measured. Analysis found that there was no significant difference in size between different countries, landscape and temperature. The number of individuals and the number of genera did not significantly differ between temperature, landscape and country however on a smaller country level there were differences in the numbers of individuals and genera at different landscapes. The number of bumblebees was affected by the landscape with more individuals found in the disturbed landscapes; it is possible that due to the foraging ability and feeding preferences that bumblebees are able to gain an advantage in a disturbed landscape. Different genera were found in different regions with high numbers of Panurgus and Panurginus found in Spain and Catalunya. The number of bumblebees was also found to be significantly related to latitude. These differences in composition in different areas could be seriously affected in the face of climate change. The effect of the local environment on bee abundance and diversity in regions throughout Europe. 1: Background and importance â€Å"If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man.† Albert Einstein 1.1: The importance of bees Bees provide the critical ecosystem service of pollination (Kearns et al 1998). Insect pollination is essential for our life as we know it. 84% of crops in the EU depend on insect pollination (Williams 1994) and one third of our diet can be attributed to insect pollination, either directly or indirectly (McGregor 1976). Of the insect pollinators it is bees which provide the most pollination, bees which are highly adapted to flower visitation, have been confirmed to be pollinators for 72.7% of crop species and it is thought they could be responsible for the pollination of another 10.2% (Williams 1994, Roubik 1995). Declines in bees point towards serious consequences for natural ecosystem process and agricultural processes (Biesmeijer et al 2006). The declines being experienced on local and regional scales present a worrying situation with habitat loss, fragmentation, agricultural intensification and pesticide use causing declines in honey bees, solitary bees, wild bees and bumble bees (Steffan-Dewenter et al 2005). The greatest diversity of bees in the world is experienced in arid and semi-arid regions of the world including the Mediterranean regions of Southern Europe (Danforth 2007). Most of the bees in the world are solitary bees (National Research Council of the National Academies 2007) and of the solitary bees the majority of them are resource specialists, oligolectic (Wcislo and Cane 1996). Oligolectics are bee species which collect pollen from one genus or species but can collect nectar from a variety of plants, they are often referred to as specialists. Polylectic bee species are generalists; they can collect pollen from a variety of flowering plants and include the honeybee (Apis) and the bumblebee (Bombus). In theory the risk of extinction is elevated in oligolectic bees as their presence and distribution is limited by just one floral host (Zayed and Packer 2007). Work by Cane et al (2006) into urban habitat fragmentation showed the abundance and richness of oligolectic bees to have declined but not to have declined in the polylectic bees. Due to the important role of bees it is essential to understand the abundance and diversity of bees across the landscape and the local factors that affect them. By understanding the local factors affecting the diversity and abundance of bees it may be possible to effectively manage and conserve bees and help to prevent any further declines in diversity and abundance. 1.2: Landscape Much of the natural habitat in Europe has been lost and the habitats with the highest species richness are the remaining semi-natural areas (Pimentel et al 1992). The impact of disturbance on insect communities is not so extensively studied as the impact on vegetation, on the studies that are available results show that different insect groups respond differently to disturbance (Steffan-Dewenter and Leschke 2003). Study by Steffan-Dewenter and Leschke (2003) on the effect of habitat management and landscape on bees and wasps in orchards in Europe showed that the vegetation was more significantly affected by the management practices than the insects. Bee species richness is correlated with the percentage of grassland in the surrounding landscape (Dauber et al 2003, Hendrickx et al 2007, Steffan-Dewenter et al 2002). The bees in the study by Hendrickx et al (2007) showed not only a decline with distance from semi-natural patches but also a decline with increasing management practices. The other groups in the study experienced increased numbers with proximity to semi-natural habitat but no significant declines with increasing agricultural management. The results for bees can be attributed due to bees having such a strong dependence on floral resources (Tscharntke et al 1998). Low plant diversity with limited floral resources may not to be able to support a high diversity of insects thus resulting in lower insect diversity and the ability to support only the generalist species (Westphal et al 2003). Proximity to floral resources and nesting sites is important as foraging distances can be fairly small. Large bumblebees such as Bombus terrestris can forage distances up to 3000m, as foraging distances are related to body size, smaller bees may only be able to forage a few metres (Westphal et al 2006). In the tropical forests of Costa Rica pasture management and the floral resources showed to have no significant impact on the diversity or abundance of bees, however deforested countryside just metres away from the forest contained a different community composition (Brosi et al 2006). The complexity of landscapes means that the impact of disturbance can vary depending on the frequency, intensity and extent of the disturbance (Samways 2005). Moderate disturbance can actually increase the diversity of the area by opening up areas for colonisation by providing ecological niches and opportunities for rarer species (Caswell 1976, Connell 1978, Petraitis et al 1989). Alternately diversity could be lowered as the dominance of opportunistic species is increased (Margalef 1968). Bees depend on floral resources for nectar and pollen and can only travel certain distances from their nesting site to reach it, both flowers and nests need to be close by. Therefore declining floral resources, and declining suitable nest sites, as experienced in large scale disturbed areas, may result in the declining numbers and diversity of bees. 1.3: Microclimate- temperature The microclimate, the lowest two metres of the atmosphere (Stoutjesdijk and Barkman 1992), is the layer of the atmosphere where the majority of plants and animals live (Unwin and Corbet 1991). The soil surface (or other substance, for example forest or concrete) influences the heat and moisture budget of the surrounding atmosphere producing localised variations in the climatic conditions, for example temperature, windspeed and humidity. The relationship between plant and microclimate is a close one with plants affecting the climatic conditions around them and the microclimate affects the factors controlling the functioning of the plant including the availability of the products required for photosynthesis. Insects benefit from this interaction and due to the close mutalistic relationship between some plant and insect species, for example plants and pollinators, are dependent on a healthy relationship between microclimate and plants. An unsuitable microclimate will lead to the deterioration of plant life and eventual death of the plant and insects dependent on it. 1.4: Insects, temperature and body size In many insects body temperature is essential in order to gain flight. An insect needs to gain enough energy to fly; it needs to raise the thoracic temperature above the temperature of the environment (Bishop and Armbruster 1999) this can be achieved by basking and endothermy (producing heat in the muscles) (Unwin and Corbet 1991). The size of the insect plays a vital role in the ability to heat up and subsequently fly and forage. A study by Casey and Joos (1983) found that the proportion of heat lost from the thorax per time unit decreases as the body mass of the insect increases, therefore larger insects are slower at gaining and loosing heat. Bishop and Armbruster (1999) also concluded that the ability to raise temperature in order to fly increases with body size making bumblebees better thermoregulators than solitary bees. Even when looking at solitary bees larger solitary bees will be better at thermoregulation than smaller solitary bees. Foraging activity can be restricted by thermoregulation factors (Heinrich 1974) and not just over winter. In the summer months foraging at high latitudes and higher temperatures may prove to be difficult for larger insects with solitary bees reaping the floral rewards. Whilst in cooler areas at lower latitudes larger bees, such as bumblebees will have the advantage (Bishop and Armbruster 1999). Tropical bumblebees have been found to be the largest bees, an exception to the rest of the findings by Peat et al (2205). They found that the mean size of bumblebees varies between different climates with colder climates having a larger mean size than those of warmer climates. Size variation of bumblebees within a region was found not to be related to temperature but other factors, possibly to improve colony foraging with different sizes able to visit different flowers (Peat et al 2005). It is not just at different temperatures, different latitudes and different elevations that there are heat constraints on the species present but also a daily sequence. Heinrich (1976) observed bees visiting flower patches and noted the day sequence process. Large insects, such as large bumblebees, are able to achieve a body temperature high enough to fly at a lower temperature than a smaller insect, for example a small solitary bee. This then means that earlier in the day the bumblebee can begin to forage and last longer into the evening when the temperature of the environment begins to fall. However in the midday heat the bumblebee may become overheated and need to retreat and cease flying for a few hours. The small solitary bee although not able to start until later and unable to continue into the evening will be able to cope in the midday heat and continue to forage (Unwin and Corbet 1991). The temperature of the area determines the foraging activity of bees and will influence the bees present in the area. What is under-researched is the effect of very localised temperature has on the bees and size of bees present. 1.5: Climate The temperature of the environment does not only determine the body temperature of the insect but also the geographical range (Gates 1993). Over the past 30years shifts in the abundance and distribution of a variety of species have been witnessed due to climate change (Parmesan and Yohe 2003). Hickling et al (2006) studied the distributions of different taxonomic groups in Britain over the last 25years to examine any shifts in range that may have occurred. A shift in distribution upwards and northwards was found in most taxonomic groups with the latitude being a more significant factor than elevation. Alterations to geographic ranges will impact different organisms in different ways and at different times in their lifecycle. It is possible that the interactions between organisms could be severely affected and possibly even destroyed, in some instances resulting in the extinction of one or both of the species. With these shifts in distributions comes the increased possibility of species extinctions, one prediction for 2050 using a mid-range climate scenario showed 15-37% of species committed to extinction (Thomas et al 2004). In order to avoid the risk of extinction species will have to be able to keep up with the changing climate by migrating at fast enough rates however barriers such as mountains and fragmented, disturbed landscapes may hinder this migration (Pearson and Dawson 2003). General climate models which observe the possible consequences of climate change show a general pattern of the increasing of the Mediterranean summer drought (Gates 1993). As a result it is expected that a shift in species composition will occur and drought conditions will lead to reduced plant cover. This will inevitably impact many insect species including pollinators, such as bees, that will lose their source of nectar and pollen. Research suggests that resource specialists are likely to be the first to suffer declines as they rely on just one plant for their pollen (Cane et al 2006). Looking at the effect of local temperatures on abundance and richness may be able to give an indication of what will follow with global climate change and thus be an aid for planning and conservation measures. 2: Aims and Objectives Bees are essential for pollination and are the key to maintaining life as we know it. Reaching and maintaining the right temperature is essential for an insect’s flight, there is evidence that reaching this temperature is related to body size but does it vary with temperature within a microclimate? Does the local temperature affect the bee diversity and abundance and will this provide any insights into what may happen in the face of global climate change? Within Europe it has been reported that it is the remaining semi-natural habitats that contain the most species richness. If this is the case it would be expected that areas of human disturbance would experience a much lower diversity and abundance. In this project the aim is to examine the effect that the local conditions, temperature and landscape, have on the abundance and genera of bees in a selection of regions across Europe. Within this there are three main objectives to be examined: To determine if the local temperature affects the abundance and diversity of bees. To determine if the surrounding landscape, disturbed or natural, affects the diversity and abundance of bees. To establish whether the size of certain genera are significantly affected by the local environment. 3: Methodology 3.1: Site selection Samples of pollinators were collected in field sites throughout Europe in the summer of 2007 as part of the CITIRAT (Climate Interactions with Terrestrial plant Interactions a Risk Assessment Tool) project. The CITIRAT project is part of the wider EU ALARM (Assessing LArge scale Risks for biodiversity with tested Methods) project (http://www.alarmproject.net/alarm/). The field sites for the CITIRAT project were pre-determined by ALARM, with the core sites situated in different regions throughout Europe allowing the study of most of the climatic regions in Europe. For each of the core sites there are two sites measuring 4km by 4km within 50km of each other. One of the two sites being predominantly natural or semi-natural and the other site a disturbed landscape. The two focal sites have being selected so that the geological and environmental parameters are as similar as possible allowing the human disturbance to be the most distinguishing features between the sites. Figure 3.1.1 shows examples of the land cover in each category. Table 3.1.1: An example of the classification of disturbed and natural sites, categories taken from the level 3 CORINE 2000 land cover classification. Disturbed Non-irrigated arable land, pastures, discontinuous urban fabric, complex cultivation procedures, fruit trees and berry plantations, agro-forestry areas, olive groves, permanently irrigated land. Natural/semi-natural Mixed forest, coniferous forest, broadleaved forest, transitional woodland-scrub, sclerophyllous vegetation, natural grasslands. Using GIS analysis the temperature for each of the disturbed and natural areas was calculated using a model which combined the elevation, slope, aspect, average daytime temperature, clear sky solar radiation maps. This model then gave the temperatures for points throughout the landscape, the hottest 10% and coldest 10% of points were selected and ranked, the top two temperature points for both hot and cold were then determined and ready for fieldwork to begin. 3.2: Sampling method Each of the two landscapes (disturbed and natural) had two sampling rounds approximately 2 weeks apart. Within each sampling round two hot and two cold temperature sites were used (as predetermined by the GIS analysis). Each temperature spot had three cluster sets of pan traps, one white, one yellow and one blue. Each cluster contained five pan traps of a single colour. Each cluster was situated five metres apart in open, low vegetation at ground level. The pan traps were left out over a two day period in dry conditions with low wind and a temperature of greater than 15 ºC. Leaving pan traps out over a two day period eradicated any daily variation in bee species present due to daily temperature fluctuations. By using all three coloured pan traps bias was reduced as a range of colour preferences could be catered for (Leong and Thorp 1999). When the samples, preserved in alcohol, were returned to Leeds the samples were sorted taking note of the number of honeybees, number of bumble bees, number of other bees, number of hoverflies and the number of butterflies. Anything else that was collected in traps was discarded. The bumblebees and other bees were removed from the sample tubes, and were dried, pinned and labelled. The bees were then identified to genus level and the results recorded. Figure 3.3.1: Map of Europe showing the ALARM core sites. The yellow dots indicate the sites used in this analysis and their ‘country’ label. Adapted from an image available at: http://www.alarmproject.net. 3.3: Analytical method Samples were collected at sites all across Europe. Time and resource restraints meant that not all of the sites sampled could be pinned and identified for use in this study. The sites used were carefully selected with sites showing high variation in elevation and therefore temperature differences chosen. Figure 3.3.1 shows the European sites used in this project and table 3.3.1 shows the latitude and longitude of the sites. From here on these ‘sites’ will be called countries to avoid confusion. Table 3.3.1: Sites used with the latitude and Longitude Country Landscape Latitude Longitude Austria Disturbed 47.5205 14.1432 Austria Natural 48.0125 15.1620 Catalunya Disturbed 41.2620 1.7714 Catalunya Natural 41.2526 1.9006 Germany Disturbed 51.5491 9.7754 Germany Natural 51.4540 12.9410 Italy Disturbed 45.6202 12.4526 Italy Natural 45.7775 12.6088 Spain Disturbed 39.3153 -4.0661 Spain Natural 39.4133 -4.0650 UK Disturbed 51.5082 -1.5310 UK Natural 51.7650 -0.4585 To calculate the diversity for each of the conditions at each of the sites the Simpson’s diversity index, which is â€Å"one of the most meaningful and robust diversity measures†(Magurran 2004) was used. The index works by calculating the probability, that from a community of infinite size, two individuals will belong to the same species. The Simpson diversity index was expressed as 1-D therefore meaning that as the Simpson’s diversity decreases as does the diversity, this logical adaptation of the index mean that the diversity of the samples could easily be calculated and compared. In order to determine if the size of bees are affected by the local conditions one genus, Halictus was chosen due to them making up a large proportion of total individuals present. To measure the Halictus samples a random number table was used to determine which specimens should be measured. All of the specimens were females and from two countries, Spain and Germany. Digital callipers were used under a microscope to measure the width of the thorax, in-between the base of the wings. The numbers of Bombus’ were looked at as well as the size of the Halictus. Bombus’ are known to be (generally) a larger body size and better thermoregulators so provide a good genus to use as an indication of distribution related to the local environment factors. The information available for use in the statistical analysis was the number of individuals, the number of genera, the temperature (hot or cold), the landscape (disturbed or natural), the country, the sample round (1 or 2), the site (either 1 or 2), the diversity (Simpson’s 1-D), the number of bumblebees, the number of solitary bees and for a selection of sites the size of Halictus. The statistical analysis was carried out using R and Minitab for the principal component analysis. Excel was used for the production of some of the graphics. Not all the data was normally distributed, distributions were checked using the Shapiro-Wilk test. The analysis used was a mixed effects model but not all data meet the assumptions so where unavoidable non-parametric tests were used, a generalised mixed effects model (glmmPQL). 4: Results Nineteen Genera were identified; a list of these genera and authorities can be viewed in the appendix A. One genus could not be confirmed despite various opinions but is suspected that it might be Panurginus. 4.1: Individuals and genera Figure 4.1.1: The mean number of individuals per sample round, error bars indicate  ±1 SE. (t66= -5.804, p= A mixed effects model was used for the analysis of the individuals. The random effects were site, landscape and country. The standard deviation estimate for country was 0.528 showing that for the countries there was a variation from the mean, this may affect the outcome of the model. The only significant factor was sample round (t66=-6.456, p= There were no significant differences in individuals within temperature, landscape, sample round or any of the interaction terms. To alleviate the problem of countries having a great variation in the numbers of individuals the model was rerun with countries as a fixed factor. This reduced the variation of the random effects and recalculated the fixed effects. Sample round remained the only significant factor (t66= 5.804, p= The dataset for genera was non-parametric so the model used was the glmmPQL. A very low standard deviation estimate was given for each of the random factors (country= 4.2: Diversity The generalised mix effects model for diversity used Simpson’s 1-D values. The estimates of standard deviation for the random effect of country were extremely low, Figure 4.1.2: The mean diversity (Simpson’s 1-D) for each country. Error bars indicate  ± 1 SE. The diversity was not significantly for any of the factors, Standard deviation between countries was low at 4.3: Bumblebees and other bees The numbers of bumblebees (Bombus spp) were used in a generalised mixed effects model (glmmPQL) in order to determine if there were significant differences in the variation between temperature, landscape and sample round. The standard deviation of country was high at 1.376 showing that within the effect of country there was a lot of variation from the mean, thus contributing to the variation in bumblebees and possibly influencing the overall model. Of the fixed factors sample round and landscape were shown to be significant. Bumblebee numbers were significantly different for sample round (t79=-3.59, p=0.001, 95%CL) and landscape (t76= -3.314, p=0.001, 95%CL). Rerunning the model with country as a fixed factor changed the results. The standard deviation of the site was low at 81= -3.153, 95%CL), sample round (p=0.001, t81 = -3.394,) and also several countries were significantly different from the control country which was Austria. Catalunya (p=0.001, t81=-3.488, 95% CL), Italy (p=0.043, t81=-2.060, 95%CL), Spain (p=0.014, t81=-2.513, 95%CL) and the UK (p=0.002, t81=3.266, 95% CL). Germany was proven to not be significantly different from Austria (P=0.392, t81=-0.861, 95%CL) (figure 4.3.3). Figure 4.3.2: The number of bumblebees per landscape. Error bars indicate  ± 1SE (t81=-3.153, p=0.002, 95%CL). Figure 4.3.1: The number of bumblebees per sample round. Error bars indicate  ± 1SE (t81=-3.394, p=0.001, 95%CL). Figure 4.3.3: The mean number of bumblebees per country, error bars represents  ± 1 SE. The number of other bees (bees that were not honeybee or bumblebees) were taken and used in a mixed effect generalised linear model (glmmPQL). The model was initially run with the random factors of country and site. The standard deviation for country was 0.968 Effect of the Local Environment on Bees Effect of the Local Environment on Bees Local Environment Europe The effect of the local environment on bee abundance and diversity in regions throughout Europe. Bees have an important ecological role; they are insect pollinators providing a crucial service. Without insect pollination human diet would be very different to how we know it now. Declines in pollinators have been reported and by attempting to understand the how the local environment affects bee abundance and diversity it may be possible to prevent any further decline. Samples were collected at six sites across Europe in each site there was a disturbed landscape and a natural landscape and within each of these a hot and a cold area. Samples were collected, pinned and identified to genera and the Halictus measured. Analysis found that there was no significant difference in size between different countries, landscape and temperature. The number of individuals and the number of genera did not significantly differ between temperature, landscape and country however on a smaller country level there were differences in the numbers of individuals and genera at different landscapes. The number of bumblebees was affected by the landscape with more individuals found in the disturbed landscapes; it is possible that due to the foraging ability and feeding preferences that bumblebees are able to gain an advantage in a disturbed landscape. Different genera were found in different regions with high numbers of Panurgus and Panurginus found in Spain and Catalunya. The number of bumblebees was also found to be significantly related to latitude. These differences in composition in different areas could be seriously affected in the face of climate change. The effect of the local environment on bee abundance and diversity in regions throughout Europe. 1: Background and importance â€Å"If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man.† Albert Einstein 1.1: The importance of bees Bees provide the critical ecosystem service of pollination (Kearns et al 1998). Insect pollination is essential for our life as we know it. 84% of crops in the EU depend on insect pollination (Williams 1994) and one third of our diet can be attributed to insect pollination, either directly or indirectly (McGregor 1976). Of the insect pollinators it is bees which provide the most pollination, bees which are highly adapted to flower visitation, have been confirmed to be pollinators for 72.7% of crop species and it is thought they could be responsible for the pollination of another 10.2% (Williams 1994, Roubik 1995). Declines in bees point towards serious consequences for natural ecosystem process and agricultural processes (Biesmeijer et al 2006). The declines being experienced on local and regional scales present a worrying situation with habitat loss, fragmentation, agricultural intensification and pesticide use causing declines in honey bees, solitary bees, wild bees and bumble bees (Steffan-Dewenter et al 2005). The greatest diversity of bees in the world is experienced in arid and semi-arid regions of the world including the Mediterranean regions of Southern Europe (Danforth 2007). Most of the bees in the world are solitary bees (National Research Council of the National Academies 2007) and of the solitary bees the majority of them are resource specialists, oligolectic (Wcislo and Cane 1996). Oligolectics are bee species which collect pollen from one genus or species but can collect nectar from a variety of plants, they are often referred to as specialists. Polylectic bee species are generalists; they can collect pollen from a variety of flowering plants and include the honeybee (Apis) and the bumblebee (Bombus). In theory the risk of extinction is elevated in oligolectic bees as their presence and distribution is limited by just one floral host (Zayed and Packer 2007). Work by Cane et al (2006) into urban habitat fragmentation showed the abundance and richness of oligolectic bees to have declined but not to have declined in the polylectic bees. Due to the important role of bees it is essential to understand the abundance and diversity of bees across the landscape and the local factors that affect them. By understanding the local factors affecting the diversity and abundance of bees it may be possible to effectively manage and conserve bees and help to prevent any further declines in diversity and abundance. 1.2: Landscape Much of the natural habitat in Europe has been lost and the habitats with the highest species richness are the remaining semi-natural areas (Pimentel et al 1992). The impact of disturbance on insect communities is not so extensively studied as the impact on vegetation, on the studies that are available results show that different insect groups respond differently to disturbance (Steffan-Dewenter and Leschke 2003). Study by Steffan-Dewenter and Leschke (2003) on the effect of habitat management and landscape on bees and wasps in orchards in Europe showed that the vegetation was more significantly affected by the management practices than the insects. Bee species richness is correlated with the percentage of grassland in the surrounding landscape (Dauber et al 2003, Hendrickx et al 2007, Steffan-Dewenter et al 2002). The bees in the study by Hendrickx et al (2007) showed not only a decline with distance from semi-natural patches but also a decline with increasing management practices. The other groups in the study experienced increased numbers with proximity to semi-natural habitat but no significant declines with increasing agricultural management. The results for bees can be attributed due to bees having such a strong dependence on floral resources (Tscharntke et al 1998). Low plant diversity with limited floral resources may not to be able to support a high diversity of insects thus resulting in lower insect diversity and the ability to support only the generalist species (Westphal et al 2003). Proximity to floral resources and nesting sites is important as foraging distances can be fairly small. Large bumblebees such as Bombus terrestris can forage distances up to 3000m, as foraging distances are related to body size, smaller bees may only be able to forage a few metres (Westphal et al 2006). In the tropical forests of Costa Rica pasture management and the floral resources showed to have no significant impact on the diversity or abundance of bees, however deforested countryside just metres away from the forest contained a different community composition (Brosi et al 2006). The complexity of landscapes means that the impact of disturbance can vary depending on the frequency, intensity and extent of the disturbance (Samways 2005). Moderate disturbance can actually increase the diversity of the area by opening up areas for colonisation by providing ecological niches and opportunities for rarer species (Caswell 1976, Connell 1978, Petraitis et al 1989). Alternately diversity could be lowered as the dominance of opportunistic species is increased (Margalef 1968). Bees depend on floral resources for nectar and pollen and can only travel certain distances from their nesting site to reach it, both flowers and nests need to be close by. Therefore declining floral resources, and declining suitable nest sites, as experienced in large scale disturbed areas, may result in the declining numbers and diversity of bees. 1.3: Microclimate- temperature The microclimate, the lowest two metres of the atmosphere (Stoutjesdijk and Barkman 1992), is the layer of the atmosphere where the majority of plants and animals live (Unwin and Corbet 1991). The soil surface (or other substance, for example forest or concrete) influences the heat and moisture budget of the surrounding atmosphere producing localised variations in the climatic conditions, for example temperature, windspeed and humidity. The relationship between plant and microclimate is a close one with plants affecting the climatic conditions around them and the microclimate affects the factors controlling the functioning of the plant including the availability of the products required for photosynthesis. Insects benefit from this interaction and due to the close mutalistic relationship between some plant and insect species, for example plants and pollinators, are dependent on a healthy relationship between microclimate and plants. An unsuitable microclimate will lead to the deterioration of plant life and eventual death of the plant and insects dependent on it. 1.4: Insects, temperature and body size In many insects body temperature is essential in order to gain flight. An insect needs to gain enough energy to fly; it needs to raise the thoracic temperature above the temperature of the environment (Bishop and Armbruster 1999) this can be achieved by basking and endothermy (producing heat in the muscles) (Unwin and Corbet 1991). The size of the insect plays a vital role in the ability to heat up and subsequently fly and forage. A study by Casey and Joos (1983) found that the proportion of heat lost from the thorax per time unit decreases as the body mass of the insect increases, therefore larger insects are slower at gaining and loosing heat. Bishop and Armbruster (1999) also concluded that the ability to raise temperature in order to fly increases with body size making bumblebees better thermoregulators than solitary bees. Even when looking at solitary bees larger solitary bees will be better at thermoregulation than smaller solitary bees. Foraging activity can be restricted by thermoregulation factors (Heinrich 1974) and not just over winter. In the summer months foraging at high latitudes and higher temperatures may prove to be difficult for larger insects with solitary bees reaping the floral rewards. Whilst in cooler areas at lower latitudes larger bees, such as bumblebees will have the advantage (Bishop and Armbruster 1999). Tropical bumblebees have been found to be the largest bees, an exception to the rest of the findings by Peat et al (2205). They found that the mean size of bumblebees varies between different climates with colder climates having a larger mean size than those of warmer climates. Size variation of bumblebees within a region was found not to be related to temperature but other factors, possibly to improve colony foraging with different sizes able to visit different flowers (Peat et al 2005). It is not just at different temperatures, different latitudes and different elevations that there are heat constraints on the species present but also a daily sequence. Heinrich (1976) observed bees visiting flower patches and noted the day sequence process. Large insects, such as large bumblebees, are able to achieve a body temperature high enough to fly at a lower temperature than a smaller insect, for example a small solitary bee. This then means that earlier in the day the bumblebee can begin to forage and last longer into the evening when the temperature of the environment begins to fall. However in the midday heat the bumblebee may become overheated and need to retreat and cease flying for a few hours. The small solitary bee although not able to start until later and unable to continue into the evening will be able to cope in the midday heat and continue to forage (Unwin and Corbet 1991). The temperature of the area determines the foraging activity of bees and will influence the bees present in the area. What is under-researched is the effect of very localised temperature has on the bees and size of bees present. 1.5: Climate The temperature of the environment does not only determine the body temperature of the insect but also the geographical range (Gates 1993). Over the past 30years shifts in the abundance and distribution of a variety of species have been witnessed due to climate change (Parmesan and Yohe 2003). Hickling et al (2006) studied the distributions of different taxonomic groups in Britain over the last 25years to examine any shifts in range that may have occurred. A shift in distribution upwards and northwards was found in most taxonomic groups with the latitude being a more significant factor than elevation. Alterations to geographic ranges will impact different organisms in different ways and at different times in their lifecycle. It is possible that the interactions between organisms could be severely affected and possibly even destroyed, in some instances resulting in the extinction of one or both of the species. With these shifts in distributions comes the increased possibility of species extinctions, one prediction for 2050 using a mid-range climate scenario showed 15-37% of species committed to extinction (Thomas et al 2004). In order to avoid the risk of extinction species will have to be able to keep up with the changing climate by migrating at fast enough rates however barriers such as mountains and fragmented, disturbed landscapes may hinder this migration (Pearson and Dawson 2003). General climate models which observe the possible consequences of climate change show a general pattern of the increasing of the Mediterranean summer drought (Gates 1993). As a result it is expected that a shift in species composition will occur and drought conditions will lead to reduced plant cover. This will inevitably impact many insect species including pollinators, such as bees, that will lose their source of nectar and pollen. Research suggests that resource specialists are likely to be the first to suffer declines as they rely on just one plant for their pollen (Cane et al 2006). Looking at the effect of local temperatures on abundance and richness may be able to give an indication of what will follow with global climate change and thus be an aid for planning and conservation measures. 2: Aims and Objectives Bees are essential for pollination and are the key to maintaining life as we know it. Reaching and maintaining the right temperature is essential for an insect’s flight, there is evidence that reaching this temperature is related to body size but does it vary with temperature within a microclimate? Does the local temperature affect the bee diversity and abundance and will this provide any insights into what may happen in the face of global climate change? Within Europe it has been reported that it is the remaining semi-natural habitats that contain the most species richness. If this is the case it would be expected that areas of human disturbance would experience a much lower diversity and abundance. In this project the aim is to examine the effect that the local conditions, temperature and landscape, have on the abundance and genera of bees in a selection of regions across Europe. Within this there are three main objectives to be examined: To determine if the local temperature affects the abundance and diversity of bees. To determine if the surrounding landscape, disturbed or natural, affects the diversity and abundance of bees. To establish whether the size of certain genera are significantly affected by the local environment. 3: Methodology 3.1: Site selection Samples of pollinators were collected in field sites throughout Europe in the summer of 2007 as part of the CITIRAT (Climate Interactions with Terrestrial plant Interactions a Risk Assessment Tool) project. The CITIRAT project is part of the wider EU ALARM (Assessing LArge scale Risks for biodiversity with tested Methods) project (http://www.alarmproject.net/alarm/). The field sites for the CITIRAT project were pre-determined by ALARM, with the core sites situated in different regions throughout Europe allowing the study of most of the climatic regions in Europe. For each of the core sites there are two sites measuring 4km by 4km within 50km of each other. One of the two sites being predominantly natural or semi-natural and the other site a disturbed landscape. The two focal sites have being selected so that the geological and environmental parameters are as similar as possible allowing the human disturbance to be the most distinguishing features between the sites. Figure 3.1.1 shows examples of the land cover in each category. Table 3.1.1: An example of the classification of disturbed and natural sites, categories taken from the level 3 CORINE 2000 land cover classification. Disturbed Non-irrigated arable land, pastures, discontinuous urban fabric, complex cultivation procedures, fruit trees and berry plantations, agro-forestry areas, olive groves, permanently irrigated land. Natural/semi-natural Mixed forest, coniferous forest, broadleaved forest, transitional woodland-scrub, sclerophyllous vegetation, natural grasslands. Using GIS analysis the temperature for each of the disturbed and natural areas was calculated using a model which combined the elevation, slope, aspect, average daytime temperature, clear sky solar radiation maps. This model then gave the temperatures for points throughout the landscape, the hottest 10% and coldest 10% of points were selected and ranked, the top two temperature points for both hot and cold were then determined and ready for fieldwork to begin. 3.2: Sampling method Each of the two landscapes (disturbed and natural) had two sampling rounds approximately 2 weeks apart. Within each sampling round two hot and two cold temperature sites were used (as predetermined by the GIS analysis). Each temperature spot had three cluster sets of pan traps, one white, one yellow and one blue. Each cluster contained five pan traps of a single colour. Each cluster was situated five metres apart in open, low vegetation at ground level. The pan traps were left out over a two day period in dry conditions with low wind and a temperature of greater than 15 ºC. Leaving pan traps out over a two day period eradicated any daily variation in bee species present due to daily temperature fluctuations. By using all three coloured pan traps bias was reduced as a range of colour preferences could be catered for (Leong and Thorp 1999). When the samples, preserved in alcohol, were returned to Leeds the samples were sorted taking note of the number of honeybees, number of bumble bees, number of other bees, number of hoverflies and the number of butterflies. Anything else that was collected in traps was discarded. The bumblebees and other bees were removed from the sample tubes, and were dried, pinned and labelled. The bees were then identified to genus level and the results recorded. Figure 3.3.1: Map of Europe showing the ALARM core sites. The yellow dots indicate the sites used in this analysis and their ‘country’ label. Adapted from an image available at: http://www.alarmproject.net. 3.3: Analytical method Samples were collected at sites all across Europe. Time and resource restraints meant that not all of the sites sampled could be pinned and identified for use in this study. The sites used were carefully selected with sites showing high variation in elevation and therefore temperature differences chosen. Figure 3.3.1 shows the European sites used in this project and table 3.3.1 shows the latitude and longitude of the sites. From here on these ‘sites’ will be called countries to avoid confusion.

The index works by calculating the probability, that from a community of infinite size, two individuals will belong to the same species. The Simpson diversity index was expressed as 1-D therefore meaning that as the Simpson’s diversity decreases as does the diversity, this logical adaptation of the index mean that the diversity of the samples could easily be calculated and compared. In order to determine if the size of bees are affected by the local conditions one genus, Halictus was chosen due to them making up a large proportion of total individuals present. To measure the Halictus samples a random number table was used to determine which specimens should be measured. All of the specimens were females and from two countries, Spain and Germany. Digital callipers were used under a microscope to measure the width of the thorax, in-between the base of the wings. The numbers of Bombus’ were looked at as well as the size of the Halictus. Bombus’ are known to be (generally) a larger body size and better thermoregulators so provide a good genus to use as an indication of distribution related to the local environment factors. The information available for use in the statistical analysis was the number of individuals, the number of genera, the temperature (hot or cold), the landscape (disturbed or natural), the country, the sample round (1 or 2), the site (either 1 or 2), the diversity (Simpson’s 1-D), the number of bumblebees, the number of solitary bees and for a selection of sites the size of Halictus. The statistical analysis was carried out using R and Minitab for the principal component analysis. Excel was used for the production of some of the graphics. Not all the data was normally distributed, distributions were checked using the Shapiro-Wilk test. The analysis used was a mixed effects model but not all data meet the assumptions so where unavoidable non-parametric tests were used, a generalised mixed effects model (glmmPQL). 4: Results Nineteen Genera were identified; a list of these genera and authorities can be viewed in the appendix A.
