physic Essays - Elementary Particles, Particle Physics, Dark Matter

Physics covers a wide range of phenomena, from elementary particles (such as quarks, neutrinos and electrons) to the largest superclusters of galaxies. Included in these phenomena are the most basic objects from which all other things are composed, and therefore physics is sometimes called the "fundamental science".[8] Physics aims to describe the various phenomenon that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things observable to humans to root causes, and then to try to connect these causes together. For example, the ancient Chinese observed that certain rocks (lodestone) were attracted to one another by some invisible force. This effect was later called magnetism, and was first rigorously studied in the 17th century. A little earlier than the Chinese, the ancient Greeks knew of other objects such as amber, that when rubbed with fur would cause a similar invisible attraction between the two. This was also first studied rigorously in the 17th century, and came to be called electricity. Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism). However, further work in the 19th century revealed that these two forces were just two different aspects of one force ? electromagnetism. This process of "unifying" forces continues today, and electromagnetism and the weak nuclear force are now considered to be two aspects of the electroweak interaction. Physics hopes to find an ultimate reason (Theory of Everything) for why natur e is as it is (see section Current research below for more information).

Econometrics Research Topic Ideas

Econometrics Research Topic Ideas One of the most difficult things about being an undergraduate student  in economics is that most schools require that students write an econometrics paper at some point in their studies. Econometrics is essentially the application of statistical and mathematical theories and perhaps some computer science to economic data. The objective is to develop empirical evidence for economics hypotheses and to predict future trends by testing economics models through statistical trials. Econometrics assists economists in analyzing large sets of data to unveil meaningful relationships among them. For instance, an econometrics scholar might attempt to find statistical evidence for answers to real-world economics questions like, does increased education spending lead to higher economic growth? with the help of econometrics methods. The Difficulty Behind Econometrics Projects While certainly important to the subject of economics, many students (and particularly those who do not particularly enjoy statistics)  find econometrics a necessary evil in their education. So when the moment arrives to find an econometrics research topic for a university term paper or project, they are at a loss. In my time as an economics professor, I have seen students  spend 90% of their time simply trying to come up with an econometrics research topic and then searching for the necessary data. But these steps need not be such a challenge. Econometrics Research Topic Ideas When it comes to your next econometrics  project, I have you covered. Ive come up with a few ideas for suitable undergraduate econometrics term papers and projects. All the data you will need to get started on your project is included, though you may choose to supplement with additional data. The data is available for download in Microsoft Excel format, but it can easily be converted to whatever format your course requires you to use. Here are two econometrics research topic ideas to consider. Within these links are paper topic prompts, research resources, important questions to consider, and data sets to work with. Okuns Law Use your econometrics term paper to test Okuns Law in the United States. Okuns Law is named for American economist Arthur Melvin Okun, who was the first to propose the existence of the relationship back in 1962. The relationship described by Okuns Law is between that of a countrys unemployment rate and that countrys production or gross national product (GNP). Spending on Imports and Disposable Income Use your econometrics term paper as an opportunity to answer questions about American spending behaviors. As incomes rise, how do households spend their new wealth and disposable income? Do they spend it on imported goods or domestic goods?

Broad Classification Of Work Motivational Theories Commerce Essay

Broad Classification Of Work Motivational Theories Commerce Essay The work motivation theories can be broadly classified as content theories and process theories. The content theories are concerned with identifying the needs that people have and how needs are prioritized. They are concerned with types of incentives that drive people to attain need fulfillment. The Maslow hierarchy theory, Fredrick Herzberg’s two factor theory and Alderfer’s ERG needs theory fall in this category. Although such a content approach has logic, is easy to understand, and can be readily translated in practice, the research evidence points out limitations. There is very little research support for these models’ theoretical basic and predictability. The trade off for simplicity sacrifices true understanding of the complexity of work motivation. On the positive side, however, the content models have given emphasis to important content factors that were largely ignored by human relationists. In addition the Alderfer’s ERG needs theory allows more flexibility and Herzberg’s two-factor theory is useful as an explanation for job satisfaction and as a point of departure for job design. The process theories are concerned with the cognitive antecedents that go into motivation and with the way they are related to one another. The theories given by Vroom, Porter and Lawler, equity theory and attribution theory fall in this category. These theories provide a much sounder explanation of work motivations. The expectancy model of Vroom and the extensions and the refinements provided by Porter and Lawler help explain the important cognitive variables and how they relate to one another in the process of work motivation. The Porter Lawler model also gives specific attention to the important relationship between performance and satisfaction. A growing research literature is somewhat supportive of these expectancy models, but conceptual and methodological problems remain. Unlike the content models, these expectancy models are relativ ely complex and difficult to translate into actual practice. They have also failed to meet the goals of prediction and control Motivation Theory 1 – Adam’s Equity Theory of Work Motivation The theory explains that a major input into job performance and satisfaction is the degree of equity or inequity that people perceive in work situations. Adam depicts a specific process of how this motivation occurs. Inequality occurs when a person perceives that the ratio of his or her outcomes to inputs and the ratio of a relevant other’s outcomes to inputs are unequal. Our Outcomes Other’s Outcomes = Inequity (over-rewarded) Our Inputs Other’s Inputs Both the inputs and the outputs of the person and the other are based upon the person’s perceptions, which are affected by age, sex, education, social status, organizational position, qualifications, and how hard the person works, etc. Outcomes consist primarily of rewards such as pay, status, promotion, a nd intrinsic interest in the job. Equity sensitivity is the ratio based upon the person’s perception of what the person is giving (inputs) and receiving (outcomes) versus the ratio of what the relevant is giving and receiving. This cognition may or may not be the same as someone else’s observation of the ratios or the same as the actual situation.

In relation to customary international law, what are the difficulties Essay

In relation to customary international law, what are the difficulties involved in determining State practice and how is it possible to separate State practice from opinio juris - Essay Example Center of discussion in this paper is International Law as the body of laws, precepts and regulatory principles that govern relationships between states on the world stage. As states interact with each other in worldly affairs, a political, economic or financial business situation may be created whereby there is a disagreement or difference of viewpoint or even rules of conduct. As a result, one or both state entities may feel cheated and may either decide to settle their differences amicably with one another on agreed terms, resort to aggressive tactics like wars and embargoes or appeal to internationally recognized institutions like the International Courts of Justice and the United Nations Organization to solve their problems. For example, the UN last year has intervened to monitor the situation in Libya arising from the formation of opposition groups seeking to overthrow the corrupt and decadent regime of Col. Muammar Gaddafi. It passed Resolution 1970 on February 26, 2011 under which it condemned the escalation of violence in Libya, noting the loss of lives and heavy civilian casualties that defined crimes against humanity and the civilian population. It demanded a ceasefire and cessation of violent activities, ensuring safety and security to both citizens as well as foreign nationals. It also pressed for safety of the media which was instrumental in bringing information as to the actual situation on the ground. Among other things, the adoption of this resolution resulted in an arms embargo, the creation of a no-fly zone and freezing of assets as recommended by a high level Committee created in the aftermath of the Arab League meeting and the Organization of Islamic Conferences on the situation. Thankfully, the situation is now returning to normalcy since Gaddafi has been deposed and killed and the rest of his family is either in exile or has been arrested or killed. At the present time, the world community especially European and US officials have asked t he Security Council to pass a similar resolution against the regime in Syria, considering the nine month crackdown on protestors in which thousands have been killed or arrested. In terms of Lord Denning’s definition, given at the judgment of the case of Trendtex Trading Corp v Central Bank of Nigeria (1977), International Law may be described as ‘the sum of the rules or usages which civilized States have agreed shall be binding upon them in their dealings with one another’. It is primarily concerned with the behavior of States, and comprises the body of principles, rules and customs recognized as binding obligations by sovereign States and international entities. Higgins points out that ‘it is a system of normative conduct that States consider obligatory to follow’ and as may be formally defined by various conventions and agreements published by the United Nations, the

Assassination of Abraham Lincoln - Essay Example The author begins the article by providing a brief discussion of some of the activities that were undertaken by the Republicans in the political year of 1992. Specifically, the article describes the origin of Abraham Lincoln from politics and how certain leaders who came after him made efforts to emulate his leadership styles. The author uses examples of leaders such as Ronald Reagan and George Bush Senior and how their contributed towards the development of the legacy of Abraham Lincoln. He uses examples of republican leaders and how their created emphasis of good aspects of Lincoln’s leadership styles hence contributing to the development of his political legacy. The major strength of the article is based on the fact that the information is properly presented in a comprehensive language, making it easy to understand. However, its major weakness lies on the fact that the author has not provided the source of his/her information. The author of this article focused on the aftermath of the assassination of Abraham Lincoln. The first page of the article indicates a picture of a group of people that appears to be in a meeting. The introductory paragraph of the article basically describes accusations that occur with regard to the assassination of Abraham Lincoln. Moreover, the author has applied pictures to create more insight of the events that unfolded after the assassination. These pictures present scenarios of past politicians, majorly after Lincoln’s death. The use of pictures in the article is its major strength. It also appears that some extent, there is excessive use pictures in the article hence presenting limited written information. This could be its major weakness. This article presents a story published on 15th March, 1979; the author focuses on the assassination of Lincoln and the events that unfolded as the investigation related to the assassination.

Cultural Characteristics of India Essay Example for Free

Cultural Characteristics of India Essay With more than half of the workforce being in agriculture, services however, is the biggest contributing factor the economic growth in India. The information technology (IT) sector is where most of the growth is taking place. Many companies in the United States are beginning to outsource their help desk and programming specialties to India where the labor is cheaper and there are an abundance of qualified individuals. In-fact many of the positions you see in IT are filled by people native to India simply because training for these specialties is limited in the U. S. For example, if you were looking to hire an Extract, Transform, and Load (ETL) developer it is highly unlikely that you will find a U. S. citizen with these skill sets, and if you did the U. S. candidate would certainly be demanding more money. India’s ability to train highly qualified IT professionals and ability to provide cheaper labor will continue to contribute to their increase in economic growth. Ultimately, it is those cultural characteristics we have discussed in class that has led India to so much growth over the last decade. They are a collectivist society, with a large power distance and a different set of value orientations from our own. Higher education is of upmost importance, and often times, much more important than interpersonal relationships. This is evident of the fact that they place so much importance on one’s education and its correlation to family status when selecting a bride/groom in an arranged marriage. India is considered a large power distance culture because there is a clear hierarchy within the family, â€Å"the father rules authoritatively, followed by the eldest son and moving down the ladder by age and sex† (Neuliep, 2009. 9). Within the Indian culture the children are expected to be obedient and many Indian children feel that their parents really don’t understand what it is like to grow up in today’s diverse society. Indian parents constantly expect their children to go to the right schools, only converse with people who share the same cultural backgro unds and to marry within their own race and religion. There are many different religions in India which include: Muslim, Hindu, Christian and Sikh. In India, even though you may share the same ethnicity if you do not share the same religious beliefs, marriage is forbidden. In my research I have come across a common theme within the Indian culture, and that is that Indian parent’s love to gossip about everything; they constantly discuss who got into what school, and who is getting married to whom. It’s not to say that Indian parents don’t want what’s best for their children because they do. In the article Indian Parents and Societal Pressure the author Arti Nehru states, â€Å"The really sad part about all of this is that parents truly want their children to be happy. But they are unsupportive in many instances because they worry about ne thing: What will people say? † The Indian culture is more of a collectivist culture who has the tendency to stress the importance of a group over the importance of the individual. Neuliep confirms that, â€Å"In collectivist cultures, people are not seen as isolated individuals. People see themselves as interdependent with others their (e. g. , their ingroup), where responsibility is shared and accountability is collective. A person’s identity is defined by his or her group memberships† (Neuliep, 2009. Pg. 41). Most of their values come from their traditional beliefs, their religious devotion and their secular spirituality. It is these value orientations that shape the way the Indian culture communicates with individuals in their own culture as well as with individuals outside of their culture. Values can affect the way people communicate within their own culture and with people of different cultures. They are â€Å"evaluative beliefs that synthesize affective and cognitive elements to orient people to the world in which they live† (Mooney, 2001, 2828). The value orientation model is used to compare high-context cultures such as the Indian collectivist culture with low-context individualistic cultures such as the United States. It can be broken down into six different categories: self, family, society, human nature, nature, and supernatural. In a collectivist culture such as the Indian culture â€Å"self† refers to how one may view themselves in relationship to others, and can further be broken down into three different sub-categories: self-identity, age, and activity. In India self-identity would suggest that people value conformity and cooperation. In India people are â€Å"interdependent with others, and for them, responsibility and accountability are shared and divided among the group members. † (Neulip, 2009, 63-64). Age for a collectivist, high-context culture is admired when they are old and conversely, in an individualistic, low-context culture, age is admired when they are young. In a collectivist culture like India the people tend be very spiritual and believe that people should embrace life. The activity one performs on a daily basis is of less importance in a country like India. Whereas in the United States, activity ften refers to how people identify themselves through their activities such as their professions and occupations. Often times when Americans are asked who they are, they will answer with what they do for a living; indicating that they tend to associate who they are, with what they do. Family within a collectivist culture such as India tends to be more authoritative in nature. The â€Å"head of the household† will make the decisions rather than having everyone work together as a democracy when making decisions. In India, families are less mobile, and will always attempt to sit down together when eating dinner. There is often a strict hierarchy that is followed among family members with the man of the house being at the top. The men and women in Indian families have very different roles within the family, which coincide with one’s hierarchal power. The male of the house makes the decisions, provides for the family and the women often times make the meals at night and take care of the children. In Indi,a family is a very important concept and marriage is considered to be sacred and is meant to last a life time. The term â€Å"society† in India can be broken down into two categories: social reciprocity and group membership. According to Neuliep â€Å"social reciprocity refers to the mutual exchanges people make in their dealings with others† (65). In collectivist cultures like India, if one asks another for a favor it is expected that an equal exchange of favors will occur. In India, group membership is often a pervasive formality; they have a tendency to join only a few different groups over a life-time. In the United States membership in a group is usually short lived, whereas in India people are highly selective and group membership is usually a prolonged commitment. This idea of a prolonged commitment to a group stems from those same cultural values that marriage does. In India, they practice arranged marriages and it is considered a lifelong commitment that is viewed as sacred. What may seem strange to the youth in the United States is actually embraced by youth in India. Many children in India feel that it gives them the ability to focus on their youth, and their education without the distraction or worry that an adolescence relationship can bring to the picture. It is also said that the youth in India â€Å"feel secure in their parent’s ability to choose an acceptable partner for them, trusting that their parents have enough experience and knowledge to do so without creating a disastrous situation† (Galt, 2011, 2). Many cultures like India believe that when marriages are not pre-arranged they tend to burn out too quickly. They believe it is because the two people have already gotten to know each other, rather than spending a life-time together after marriage getting to know each other. Marrying a person you don’t know gives one a lifetime to learn to love them, as opposed to the American ideal of learning a person inside and out before entering into marriage† (Galt, 2011, 3). In the United States, many believe that the idea of an arranged marriage is something that is forced upon the two getting married. This however isn’t true, in India before a marriage can become official the bride and groom are afforded the opportunity to meet each other to decide if they would like to go forward with the marriage. You might be surprised to hear that any rejection to a proposed marriage rarely occurs, and more often than not the proposed bride and groom will go through with the wedding as planned. This is because the parents of the bride and groom do their due-diligence and will often times spend years looking for a suitable bride or groom. They spend countless hours meeting with the families and friends, â€Å"considering hundreds of different aspects and comparison points before the potential bride and groom ever meet each other† (Galt, 2011, 6). In many ways the Indian culture is different than our own, we have the tendency to be more of an individualistic culture while they tend be more collectivist. We are considered a low-context culture, while India is considered a high-context culture. We value or independence and look out for our own self-interests over that of the group. In India, they value the group over the individual and believe that if one fails, they all fail. Even though we may differ culturally we are still similar in many ways, the biggest being our level of diversity; we are both comprised of many different values, ethnicities, and religious beliefs.

Maxims and Masks: The Epigram in The Importance of Being Earnest Essay

Maxims and Masks: The Epigram in "The Importance of Being Earnest" Oscar Wilde frames "The Importance of Being Earnest" around the paradoxical epigram, a skewering metaphor for the play's central theme of division of truth and identity that hints at a homosexual subtext. Other targets of Wilde's absurd yet grounded wit are the social conventions of his stuffy Victorian society, which are exposed as a "shallow mask of manners" (1655). Aided by clever wordplay, frantic misunderstanding, and dissonance of knowledge between the characters and the audience, devices that are now staples of contemporary theater and situation comedy, "Earnest" suggests that, especially in "civilized" society, we all lead double lives that force upon us a variety of postures, an idea with which the closeted (until his public charge for sodomy) homosexual Wilde was understandably obsessed. The play's initial thrust is in its exploration of bisexual identities. Algernon's and Jack's "Bunburys" initially function as separate geographic personas for the city and country, simple escapes from nagging social obligations. However, the homoerotic connotations of the punning name (even the double "bu"'s, which serve mostly an alliterative purpose, insinuate a union of similarities, and "Bunbury" rhymes with "buggery," British slang for sodomy) flare up when paired with Algernon's repeated assaults on marriage: ALGERNON. "...She will place me next to Mary Farquhar, who always flirts with her own husband across the dinner table. That is not very pleasant. Indeed, it is not even decent ... and that sort of thing is enormously on the increase. The amount of women in London who flirt with their own husbands is perfectly scandalous. It looks so bad. It i... ... he was inextricably associated but from which he could just as easily distance himself via a pithy saying, but he treats the tension of homosexuality, his own mask, more seriously. Jack is never ready to admit his entrance into the Bunbury underworld, and we never learn from Algernon the necessary rules of conduct. The personification of homosexuality as a character's double is not surprising - some critics argue that Dr. Jekyl's evil counterpart, Mr. Hyde, has some homosexual leanings - as such a controversial and, perhaps, embarrassing topic can be more easily disguised and obscured in the murky depths of the doppelganger tale. Today, with scientific evidence backing an opinion that places individuals' sexual preferences on a sliding scale from full heterosexuality to full homosexuality, the simple bifurcated view of sexuality in literature may soon be obsolete.

Is it ethical to feed live food to reptiles

Is it ethical to feed live food to exotic pets? Abstract Live food items are often fed to exotic pet species whether they be birds, amphibians, reptiles or mammals. This raises issues of welfare, both of the animals fed live prey Items and the prey Itself. Concerns over live food welfare are particularly marked In the feeding of vertebrate prey Items and evidence presented here shows the prolonged time taken for rodents to die, this fuelling these concerns.And yet the welfare of all exotic pets relies both on providing optimal nutrition and ensuring, as such as possible, that their natural behaviors can be expressed. Does that mean that predatory species must be fed live prey? This paper discusses this problem and seeks potential solutions. Introduction Many of the â€Å"exotic† species that are kept as pets (companion animals) or for study, or which form part of a zoo or rescue centre, are wholly or partly carnivorous and therefore require food of animal origin.Many omnivores also feed In part on live or dead animals and some essentially herbivorous/carnivorous species, such as finches (Freeloading), require invertebrate food when they are nestlings. In this paper emphasis is on the provision of still living food, but brief mention will be made of dead animals. The discussion relates mainly to live food given to captive exotic animals but it must be remembered that free-living Individuals also kill and eat live prey. The use of live food Food comprising live animals or their derivatives is widely considered to serve two main purposes.First, from a nutritive perspective, It contains important, sometimes essential, amino acids, vitamins and other nutrients; secondly, from a behavioral viewpoint It provides captive animals with stimulation, especially when It Is resented to them in an imaginative way, providing a very important form of environmental enrichment. The subject of â€Å"live-feeding† of animals in zoos and private collections has become a specialist topic, with numerous papers in the literature about how best such diets should be chosen and presented. These include precautions to minimize damage to the prey species by attacks from the animals provided as live food. O be well-substantiated; as noted above, it provides behavioral enrichment and represents a natural or near-natural method of providing essential nutrition . There s, however, another important consideration, which is sometimes forgotten or ignored. This is the question of the wellbeing of the live food that is being offered. After all, the food consists of living animals which, regardless of their taxonomic status, may be subjected to and affected by stresses, including pain during the period before and during being eaten. There are several stages at which the prey species may be subjected to stresses.The first of these is during production or collection. Live food is either bred in captivity or collected in the wild and in many cases such breeding or c ollection may involve stress for the animals involved. When offered as food, prior to being devoured the live food prey item is often in what for it is an unusual, an â€Å"alien† environment. It may, for example, be exposed to abnormally high temperatures or bright lights, rendering the individual, by definition, vulnerable to attack/apprehension by the animal to which it is being fed.The key welfare issue for many animals provided as live food will be when they are being devoured. Some live food is killed almost instantaneously by the predator, using physical or chemical means from trauma to veneration, both of these potentially rendering the prey immobile while losing consciousness. In such circumstances there may be little in risk of poor welfare. But often death takes much longer – for instance, a rodent constricted and thus killed by suffocation by a snake, or a cockroach dismembered while it is still alive.Some prey items may be swallowed whole and are therefore still alive – and presumably conscious – for some time until they die of asphyxia or the effect of the predator's gastric Juices; If not immediately devoured uneaten prey may be taken and consumed abstinently, perhaps on another day, but in the meantime it has to survive in an alien environment, often without water, food or appropriate shelter. Sometimes the prey item is never eaten, either because the predator is no longer hungry or because the prey escapes.As a result, it may die as a result of starvation, dehydration, hyperthermia or hypothermia in the predator's cage. It may, alternatively, establish itself in that cage or escape into the home/zoo environment. Here crickets (Grilled) are the best example. The debate Vertebrate food Some decades ago concern began to be voiced by some individuals and certain institutions about the practice of feeding live vertebrates to captive mammals, birds and reptiles. The methods employed began to be subjected to greater scruti ny and criticism as a greater understanding of, and sensitivity to, issues of animal welfare evolved.Society of London) introduced a ban on the feeding of living vertebrate food to its captive reptiles and instead to train the latter to take freshly-killed prey or items (for example, a freshly dead rabbit) that could be moved to simulate life or placed in an unusual environment, such as a hollow tube, to interest the hungry predator. In Britain, at any rate, many other zoos and herpetologists followed suit and by the late asses the use of dead, not living, prey was considered to be â€Å"good practice†.During the decade of the asses claims were regularly made by animal welfare groups that live-feeding was â€Å"illegal† in the I-J but these assertions were countered in lectures and articles (1). The point was made that there was no specific legal ban on live- feeding but that such a practice might lead to a prosecution under the Protection of Animals Acts (2). Herpetol ogists who still wanted to feed live food to their charges ere encouraged to take steps to minimize suffering in various ways – for example, by not leaving live food in the various for long periods of time and by providing shelter and water for it.Those recommendations in Britain were in a large part a modification and refinement of the approach taken by the senior author nearly a decade beforehand, when, in an attempt to encourage a more humane approach to live-feeding of snakes in East Africa, a document was drawn up by the Kenya Society for the Prevention of Cruelty to Animals. (KAPPA). This is reproduced as Appendix A. Force-feeding† of non-living food is also a possibility, particularly used for ‘difficult' species such as Royal pythons (Python argues) but this can be stressful.Another argument used on both sides of the Atlantic, to dissuade reptile-keepers from feeding live vertebrate food was that the latter could easily attack and damage the predator speci es. Thus, for instance, live rodents put in Bavaria as food can cause severe skin lesions in snakes (3, 4, 5). Having said that, a casual glance through online video clips, as detailed further below, shows that live vertebrate prey are still fed to pitiless by a number of keepers. Invertebrate food Questioning the feeding of live invertebrates to captive animals is less common even today .In the asses an â€Å"animal rights† group based in Scotland lobbied for more awareness of the welfare needs of invertebrate animals and included in their concerns the use of crickets, maelstroms and other species as food items for captive mammals, birds and reptiles. In the past two decades interest amongst veterinarians and others in the health and welfare of invertebrates has grown (6, 7). In its wake, discussion and studies on whether or not invertebrates â€Å"suffer† pain have become reverent (7), including some limited analysis and discussions of the ethical considerations of u sing these animals as live prey.A problem, of course, is that the term â€Å"invertebrate† is very broad, covering around 30 distinct phyla, and the ability of such animals to react to a noxious stimulus varies greatly between, say, a coelenterate that has no generalized nervous system and a cephalic with a well-developed nervous system and pain responses (7). The main groups of invertebrate that are used as food for other animals are arthropods, phyla produce endorphins and may, therefore, be able not only to respond to pain by appropriate escape behavior but be aware of it.Research on the nematode Conservationist elegant, for instance, has shown that activation, an invertebrate homologue of morphogenesis, together with improprieties, modulates aversive activity that mimics behaviors associated with chronic pain in vertebrates (9). While such primitive species can exhibit inception, it would be questioned by many as to whether they feel pain, defined as ‘an unpleasant sensory and emotional experience associated with actual or potential tissue damage' (italics added) (10).Even a single- led amoeba moves away from a noxious stimulus, but cannot be said to have an emotional response – so where on the evolutionary ‘ladder' does such a response occur? Certainly there are behavioral indicators of pain in several crustacean species (11) and some mollusks (12). In some situations such as the use of live insects in biomedical research, the approach advocated by certain authors has been â€Å"to give them (invertebrates) the benefit of the doubt† and therefore (for example) to employ an anesthetic agent when a procedure to be performed that might cause pain (13).Such a precautionary Renville has not apparently, however, been applied to the use of these same species as live food for mammals, birds or reptiles – and probably would not be realistic. We are, after all, here in a situation where the benefits of one species, the predat or, must be weighed against those of the prey species. Such is the very essence of nature. Hopefully, wherever possible, in a captive environment the welfare needs of both predator and prey can be considered and predator species trained to accept dead prey rather than live. ‘ A preliminary study of welfare of live prey speciesPerhaps a start on such a Journey is to ask for evidence regarding the welfare of prey species when being fed to a predator species. For that reason, we present here a preliminary study using online You Tube videos of various captive reptiles as the predator and mice, rats and crickets as live prey items. Clearly this cannot be a controlled study, but the videos were sampled by accessing the first ten adequate clips defined by ‘reptile eats live mouse', ‘reptile eats live rat', and ‘reptile eats live locust' and recording the time taken from apprehension of the prey item to death as determined by the time of last movement of prey item.It could be argued that the prey species may not lose consciousness until after that period and, in some cases, vivification by the prey item may occur after the last obvious movement, but in those documented in Table 1 this was not the case. The time to death as estimated by cessation of any movement was 62Ð’Â ±29 seconds for mice, 54Ð’Â ±21 seconds for rats and 18Ð’Â ±17 seconds for locusts, with ranges from 38 to 120 seconds for the mice, 24-82 seconds for the rats and 5-62 seconds for the locusts .These figures are clearly influenced by the size of both prey and of predator. Euthanasia of laboratory rodents by carbon dioxide may take 2-3 minutes (14) while cervical dislocation successfully killed animals apparently instantaneously in 79% of animals in one study (15). In another study electroencephalographic activity during the 30 seconds immediately (at 5 to 10 s), 10-15 seconds after exposure to 100% CO, 15-20 seconds after decapitation and at 20-25 seconds with cardi ac arrest caused by KC injection but not after administration of 70% CO (15).A painful and fear-provoking death taking p to 2 minutes as seen in many live food subjects would not, we argue, be acceptable in any circumstances. Interestingly, few if any rodents seemed aware that a predator shared the various with them, many mice actively investigating the snake until the moment of attack. Other rodents in the enclosure did not appear to show behavioral evidence of fear even when other rodents in the same various were attacked, constricted and killed.On the other hand, the fear and pain indicated by rapid movements and vacillations of the prey item, was clear in many of the cases as noted in Table 1 . These author found it disturbing to watch the video clips in many cases and we would argue that the suffering of prey species in many of these video clips and in many is contrary to the requirements of the Animal Welfare Act (2006) in the United Kingdom, as discussed further below. Discus sion There can be no hard-and-fast rules about the feeding of live food to captive animals.However we advocate that, if it is not necessary to sustain the life of the prey species in order to stimulate the predator to pretend and swallow, live-feeding should not take place.. When such a feeding practice is necessary – and is not De facto in intervention of legislation – it should be carried out with care and sensitivity and follow a code of practice. As noted at the beginning of this paper, there are two elements to live-feeding – the predator and the prey – and these both warrant a humane approach.Although reptiles have attracted particular attention in the debate about live-feeding, other carnivorous tax have also come under some scrutiny, especially in Europe. The feeding of large felid such as lions, tigers and cheetahs with live vertebrates, such as rodents or alligators, has long ceased to be accepted practice in zoos in cost of Europe. The use of l iving animals, such as mice or quail, to encourage falconers' birds and wildlife casualties to perfect their hunting skills has, likewise, been officially phased-out.Some of the practices alluded to above have stopped because of public attitudes but legislation has also, indirectly, had a result. Thus, for example, the I-J Animal Welfare Act 2006, while not specifically outlawing the feeding of live food to carnivorous species, puts an onus of responsibility on keepers on a duty of care to all animals in their possession and thus an obligation to ensure as far as possible that ere species are killed before being offered as food.

A picture is worth a thousand words

You've heard it so many times that it sounds trite. But a picture really IS worth a thousand words. And if a dream is a very special kind of picture, how much is IT worth?Maybe more? What about very simple pictures and very simple dreams? No doubt they're worth a little bit less than complex, elaborate ones. Or are they?In my psychotherapy course one day, I presented my undergraduate students with these questions. â€Å"Here's a very simple dream from a psychotherapy client I worked with years ago. I won't tell you anything about the client. I'll just tell you his dream, and then lets see what we can discover about him by exploring it†¦Ã¢â‚¬ ¦ O.K? Here's the dream:†Ã¢â‚¬Å"I was wearing a white shirt and a purple tie.†The students just stare at me, expecting more to come. â€Å"No,† I explain, â€Å"that's it. That's the dream. Now let's start to explore it.†I then lead them through a group process of free associating to the dream (much like I describe on the Working and Playing with Dreams Page). â€Å"Just let your imagination go. Take every element of the dream and just let your mind wander on it. Whatever comes to mind. Don't censor anything, that's important.There is no right or wrong. It can be a fun, playful exercise – although the results sometimes may be serious and powerful. Freud thought that free association bypasses the defenses of rational, logical thinking and unlocks deeper links within the unconscious. It opens one up to fantasy, symbolism, and emotion – the very place from which dreams spring.†Here is a list of some of the associations the students come up with. For the purpose of this article I've organized them somewhat, whereas during the actual exercise the ideas surface in a much more freewheeling stream of consciousness:PURPLE †¦. royalty, bruises, choking, holding one's breath, grief, a combination of blue and pink, goes well with black, The Color of PurpleTIE †¦. formal att ire, going to work, phallic symbol, tied up, being tied to something, chokes the neck, confiningPURPLE TIE †¦. unconventional, stands out, rebellious, showing offWHITE †¦. clean, pure, unstained, â€Å"good,† lightSHIRT †¦. the top part, covered up, tucked in, stuffed shirt, where are the pants?WHITE SHIRT†¦. conventional, boring, going to work, going to church, corporate AmericaWHITE SHIRT AND PURPLE TIE†¦. unusual combination, contradictory combination, very unconventional, tie really stands outDEPLETION?†¦. there's nobody else in the dream, it's so static, there's nothing happening, where are the feelings?After we finish this free associating, I then describe the client to the class.At the time Dan had the dream, he was 23 years old. I would describe him as a quiet, held-back person who was very confined (the tie) in how he talked, behaved, and felt towards others. Put bluntly, people found him rather boring to be with (white shirt). His emoti onal and interpersonal life were choked (the tie).He had almost no friends and felt little connection to his family (the tie again). Other than going to his tedious job (white shirt) as a low level technician for a computer company, essentially nothing was happening in his static, uneventful life (depletion).Dan was also very limited in understanding anything but the most surface, top-level (shirt) characteristics of his personality. Although outwardly conventional in how he dressed and acted at his job (white shirt), secretly he felt rebellious against authority (purple tie on white shirt) and generally superior (purple) to most people.He liked to think of himself as a political activist who firmly believed in the rights of abused (purple) people and felt more tied to them than anyone else. Comparing outside to inside, he was a bit of a contradiction (white shirt on purple tie).

The Right Climate

The Right Climate The Right Climate The Right Climate By Sharon With some words, a single letter can completely change the meaning. Take the letter c and the words climactic and climatic. Theres not much difference in spelling and the words even sound the same, but theres a world of difference in meaning. Climactic Climactic comes from the word climax. This has to do with the progression of events, in which the climactic moment is the moment of greatest intensity. Its that point in a serial killer thriller where it looks like the villain is going to win out against the hero. Its that point when feelings are at their highest. It can also be used to indicate a pivotal moment in history. Example: The climactic moment in the early history of man came when our ancestors left the trees and began to walk on the ground. Climatic Climatic on the other hand is all about the climate. If you can use the word weather, then climatic is the word you want. Example: Severe climatic conditions led to snow storms in July. Putting It All Together Now you know the difference, it is easy to tell that the climatic conditions of the Ice Age represented the climactic period of the age of the dinosaurs.

Globalization and the Impact of Supranational Organizations Essay

Globalization and the Impact of Supranational Organizations - Essay Example The formation of the EU brought together countries in Western Europe as well as those in Eastern Europe that had their allegiance to the communist regime in Russia. Therefore, the EU had great promise for it members and have achieved tremendous step in developing trade and commerce among its member states and other geopolitical regions.2 However, though the EU have reshaped the tradition geopolitical that existed during the Great War and World War II it has so many challenges, and it’s in the brink of disintegrating.3 The British for example has contemplated moving it country out of the EU because the institution undermine national interest for the interest of the Union. Moreover, small economies such as Portugal, Greece and Denmark complain of unfairness in trade policies and exploitation of their market by big economies in the EU.4 I agree that the motive of the formation of the EU was to poster peace among the European countries that had spent long period fighting over bother disputes and annexation of new territories by strong nations.5 Therefore, political leaders believed that if country would cooperate to trade with each other there would be minimal aggression among nations and people would gear up to trade for their own benefit and that of their country. I concur that the EU represent a community of nations and states that have varied cultural and national identities. However, the cultural and national differences are united under the umbrella of economic and political union. Therefore, the EU has enhanced integration as people get to know each other better and thus producing a stable social, economic and political Union. However, I agree that there are problem facing the EU from skepticism to suspicion, and this is threatening the future of the world strongest economic integration.6 I agree that the European Union was

Finding proper article from the daily press or other sources n writing 2 pages report about article - Essay Example This brief paper discusses some of the important issues in international trade relations. The world economy is in a recession brought about by the sub-prime mortgage crisis in the United States which started sometime in 2007 but later spread worldwide. Because of it many developed countries are facing financial and economic crises as a consequence as seen in the sovereign debt crisis in European countries such as the PIIGS (Portugal, Ireland, Italy, Greece and Spain) which undermined the euro currency and unity of the European Union. It is a crisis of unprecedented proportions which had adversely affected world trade in general. Recent news reports as seen in the international media point to a lingering crisis that had defied easy solutions. World trade today is conducted mostly under the WTO supervision but there are many trade blocs now in existence that grant special most favored nation status (MFN) to some countries that trade with each other. This is a violation of the WTO rules that state countries should let free trade prevail through its non-discrimination policy in place. An example of a specific trade bloc is the so-called G-20 (or group of 20) consisting of the twenty most economically powerful countries of the world. However, this group failed to produce a single plan of action that will adequately address the Great Recession in contrast to the Great Depression of 1933. The world today is facing similar challenges in world order as economies are facing stubbornly high unemployment rates such as the U. S. and Europe. A G-20 meeting held in Seoul (South Korea) last year to address the most pressing issues failed to come up with a solution as member-countries could not agree on what steps to take. This is a dangerous situation which had frayed international trade relations because of some massive international trade imbalances of some countries (China and Germany in
