Clinical immunology - Essay Example The allergen specific test is conducted using IgE antibodies which are found in mucous membranes, lungs and even the skin. The skin prick test on the other hand is external and more of an observation of the skin’s reaction to the allergens therefore house dust termites allergen cannot be detected through it (Sicherer,2012). Question 3 The major allergens in milk are casein and whey which are the components of milk that trigger reaction with the IgE. In peanut, there is the Ara h1 which is contained in the cotyledon and looks like vicilin (Tan , Lebeck & Nehlsen-Cannarella , 2012). Peanut and tree nuts may both test positive to a test but this does not necessarily mean that the said person is allergic to both since there are false positives. This means the child can test positive but still eat the food without having any problem. It is a kind of seed storage that triggers the reaction with IgE. In eggs, there are the ovamucoid and ovalbumin which have been identified as the maj or allergens, there are lesser ones. These two are found in the egg white (Bellanti, 2011). Question 4 Th-2 cells triggers the activation of mast cells, B cells and eosinophils that produce IgE antibodies. Th-2 produces IL-4, IL-5, IL-6, IL-13 and it also regulates eosinophil and B cell mediated responses. IL-17 is a group of cytokines that support inflammation that are produced by activated memory cells. This cytokine takes part in the creation of an immunological response that is dependent on Th-2 cells. This happens through the introduction of cytokines derived by Th-2 (Tan, Lebeck & Nehlsen-Cannarella, 2012).This is supported by the inflammation of the eosiniphil. The characteristics of response induced by different IL-17 all comes down to their structure. These differences therefore determine their functions biologically. Question 5 Histamine is organic and also a nitrogen compound that is normally involved in immune responses and it also regulates the physiological functions o f the gut. It activates inflammatory response when it acts as a neurotransmitter. Basophils produce histamine and by studying their release assay, the physician is able to determine the main allergy/asthma.PGD2 binds to receptor PTGDR and CRTH2; it is produced by mast cells and is very critical when it comes to the development of asthma and other allergic diseases. This makes it an important aspect when treatment of an allergy victim is done. The release assay can show the intensity of the allergy hence helping the physician determine the best medication or therapy. Eosinophil Cationic Protein can also be called ribonuclease 3 and is related to allergies because when an allergic reaction occurs, there number of ECP in the body rises significantly especially in areas with inflammations. Question 6 Hygiene hypothesis states that when one is not exposed to infectious agents at an early childhood stage, their chances of being susceptible to allergic diseases since the development of the ir immune system is suppressed hence making them have an immune system that can barely defend the body (Tan , Lebeck & Nehlsen-Cannarella , 2012).The polarized response by Th1 is not introduced to the system early enough

Baseball economics Essay Example | Topics and Well Written Essays - 500 words

Baseball economics - Essay Example A libertarian is one who prioritizes individual rights over the welfare of the state, one who advocates maximizing individual rights and minimizing the role of the state (AHD, 2000a). On the other hand, utilitarianism is the belief that the value of a thing or an action is determined by its utility or usefulness (AHD, 2000b). Bowie Kuhn's view is that the introduction of massive cable television broadcasts of baseball will be economically bad for the sport because it will reduce gate receipts and network television revenues, as well a make watching baseball games available to cities without the consent of anybody in baseball management. From the point of view of baseball team owners, who derive revenues from the games, Kuhn's view is libertarian and anti-utilitarian. It prioritizes the rights of the baseball team owners and those of baseball management. However, from the point of view of baseball fans, it is anti-libertarian because it prioritizes the welfare of a few over those of t he general public.

Veronica Decides To Die :: essays research papers

What is reality? Webster’s Unabridged Dictionary defines it as: something that exists independently of ideas concerning it; something that exists independently of all other things and from which all other things derive; something that constitutes a real or actual thing, as distinguished from something that is merely apparent. So, what defines reality? I mean can anyone, in all honesty, construct a concrete reproduction in which to turn and point proclaiming once and for all, â€Å"There, I give you reality in the flesh.† The answer simply is no. For as, the character, Dr. Igor stated â€Å". . . Other things, however, become fixed because more and more people believe that’s the way they should be (167).† Reality is nothing more than a socially accepted opinion – a perception inherently subjective. This very principle is the driving force behind Paulo Coelho’s introspective novel, Veronica Decides To Die. Veronica Decides to Die is an interesting story about a young woman called "Veronica" who wants to die but her suicide is not successful and she finds herself in "Villet", a place for the both the insane, as well as, the sane. Although she insists on pursuing the end she has chosen, some events, relationships, and her doctor's trick changes her view toward life. This novel is colored by the author's intimate knowledge of the world of mental hospitals, the relationships, and the comfort and anxiety of living in such a place. Coelho’s story of insanity and madness in contrast to the monotony of life provokes the feeling of self-discovery and the power of challenging all limitations and traditions. In this atmosphere created by Coelho, you learn that being different doesn't mean being mad and you understand that reality is something the majority deems to be, not necessary the best or the most logical one. It is in the vivid moments of Veronica Decides To Die that you can feel love and religious beliefs are the most important feelings one can have in one's life. You also recognize how one can stop one's feelings like fear, hatred and love and let them emerge in a way which makes one fresh without any "vitrol" (mind's bitterness), the poison believed to be the cause of insanity. Paulo Coelho first won my heart with his work entitled, The Alchemist, and with Veronica Decides To Die he secured a permanent place there. I must say that this particular novel was, at times, hard for me to read – not for any technical fault on Coelho’s part – because the story being told in many ways is my life.

Gender Socialization in American Social Institutions Essay

Socialization refers to how people learn different cultures and learn to live with the various aspects of the cultures. For an individual, socialization provides an opportunity to gain various habits and skills that are necessary for participating and acting at various levels within the society. For the wider society, socialization enables different people to exchange moral norms, values, attitudes, social roles, languages, motives and so forth, thereby attaining a form of social and cultural stability (Sapiro, 1990). Socialization is affected by many factors, which have contributed to factors such as social stratification with particular with reference to gender among various societies. Many social theories have suggested that gender is a core cause of social stratification in the American Society (Stone, 2001; Andersen & Taylor, 2005; Levinson, Cookson & Sadovnik, 2002; Giddens & Griffiths, 2006). Social stratification with respect to gender has been noted in many areas such as place of worship, schools, workplaces, and many other areas that involve social interactions. According to Andersen and Taylor (2005), the various methods used in interaction in different institutions lead to stratification since males usually tend to dominate the social scene, thus creating a situation whereby females have to play a second role in socialization. This paper will evaluate the methods of socialization used by people in different American educational institutions with particular reference to the role of gender in the social scene. The format of the paper will involve a brief discussion of the various aspects of socialization in the American context followed by a discussion of the methods of gender socialization in American social educational institutions. Gender socialization among Americans According to Stone (2001), the American society places a lot of importance in the role of the family as the basic social unit of the society. In fact, the evidence for this is shown by the abundance in most libraries of published materials regarding marriage and family life in the United States. The interest in family life is instigated by the fact that there are various instances of gender interaction such as those involving children; between children and their parents; between parents; and between parents and their in-laws (Stone, 2001). An obvious gender interaction that is usually less mentioned is that between any parent and mother-in–law or father-in-law of the opposite sex. The aspect of mother in law in particular has been a problem to many couples in the American society. In this context, Stone (2001) quotes Eppie Lederer who commented on the persistent problem associated with mothers-in-law by asking the question â€Å"Must we outlaw the mother in law? † The products of family life, that is children, also socialise differently depending on where they are. Andersen and Taylor (2005) note that gender socialization among children is impacted upon by peers, parents, the media, schools, religious institutions and forth. It is at the child level that various paths of gender socialization are charted. For instance, in schools girls usually get involved in communal games and like getting into groups whereas boys tend to put interest in games that are individualistic (Andersen & Taylor, 2005). The same authors also note that girls play more freely when they are involved in same sex groups. On the other hand, boys tend to wield power over girls when they play with them and have a tendency to create laws of play over girls. This is perhaps what leads to men’s dominance in scenes in later life (Andersen & Taylor, 2005; Stone, 2001). Methods of gender socialization in American educational and religious institutions As is the case in all societies, socialization occurs at all stages of life, not just in childhood stages. The attributes displayed by children in their early days such as gender-typed forms of games are indicator of behavior that appear later during adult life. The aspects of competitive play displayed by boys prepare them for the kind socialization environment they encounter as adults. Giddens and Griffiths (2006) note that boys engage in more aggressive socialization activities because in future they get active in activities such as sports; and the large groups they socialize with also teach them to cooperate and compete when working together later in life. Among girls, there is a slightly different approach to socialization. Andersen and Taylor (2005) note that learn in the same way as girls but they don’t tend to value the attributes such as highly as boys or men even though these attributes are no less important to them. Thus, gender socialization in various American educational institutions is based on these attributes as discussed in the following sections. Gender socialization in schools Schools in have a distinct influence on gender socialization because of the considerable amount to time children spend them (Cookson, 1990). Teachers of either sex have different expectations for boys and girls. According to research findings, boys in American schools call out answers about eight times more than girls (Andersen & Taylor, 2005). This makes boys get more attention from their teachers than girls. This point is emphasized by the fact that when teachers of either sex respond to the boys they increase the boys’ level of perceived importance. Another level of socialization in schools is the kind of books used in class. The kind of messages depicted in the books usually determine the kind of socialization that children have later in life or among themselves (Levinson, Cookson & Sadovnik, 2002). If a person of a certain gender is used as a central figure and is portrayed to be powerful or a genius, a mentality is developed among children that people of that gender are powerful in all dimensions. Most of the characters depicted as such are men. Gender socialization and religion Religion is one of the aspects of gender socialization that is often overlooked in the American society. Different religious groups lay emphasis on different aspects of their culture such as gender differences. For instance, most Judeo-Christian religions found in the United States put much emphasis on gender, with a common perspective that men are superior to women. In religions that embrace Orthodox Judaism, men offer prayer to God thanking him for not having made a slave of woman for them. In addition, many other religions in the United States exclude women from leadership in religious functions to signify that women hold a lower position in the society (Levinson, Cookson & Sadovnik, 2002). Aside from the religions that belittle gender, socialization in Christian and Muslim faiths encourages some form of gender equity (Cookson, 1990). Thus in both churches and mosques, women constantly use what they learn based on their faiths to question racist practices and other forms of unfair treatment by men. Along this line, protestant and evangelical churches in the United States campaign for shared household roles and equal job opportunities as part of socialization between men and women (Stone, 2001). Gender socialization and the media Different forms of media such as magazines, film, television, music and many others have a lot of influence on the kind of socialization in the United States. Communication through the various forms of media is facilitated through features such as cartoons, narrations, messages in music and so forth. Men and women play different roles in the media industry and this determines show they socialize at various levels. But a common tendency is that men are usually portrayed as more powerful figure in various media by their dominance in films, sports, and many other activities. This has changed how people view various forms of media and stratified the society (particularly learning institutions) in terms of popularity of some programs. Television in the United States has been criticized for portraying unrealistic images of women and men with respect to their appearance and age (Stone, 2001). There is a common opinion that women are usually portrayed provocatively on television in dresses such as underwear, nightwear, swimsuits and so forth. Media images in social scenes such as social halls, school halls, colleges and other institutions in the United States and so on are criticized for depicting white men as exercising higher authority than white women as well as black men and black women. Many advertisements in social settings also have the same tendency of depicting the male gender as being superior to the female gender (Stone, 2001). Gender socialization and employment in educational institutions Workplaces as schools are characterized by people of either gender playing different roles. The American system of job classification us characterized by hierarchical organizations which put men and women in different job capacities. For instance, most principals in schools and superintendents of colleges are men (Andersen & Taylor, 2005). This therefore creates an ill-advised notion that leaders in social institutions are always men. Conclusion It is evident that various from of gender socialization in educational institutions such as schools, colleges, churches, social halls and so forth in the United States is greatly influenced by the kind of socialization that takes place in elementary levels of education such as junior schools. In addition, the kind of behavior that boys and girls are exposed to is carried into adult life. This is shown in many organizations that disseminate knowledge such as colleges, most of which portray men as being superior to women. References Andersen, M. L. and Taylor H. F. (2005).

Revolutionizing Renaissance Inventions An Age Of...

Matty Rhee Kirill Taranouchtchenko World Civilization 1 (Period G) 5/28/16 Revolutionizing Renaissance Inventions The Renaissance was a historical time period in Europe succeeding the Middle Ages. It was an era of rebirth as well as an age of discovery and creation. The term â€Å"renaissance† is a French word. The word â€Å"naissance† literally means birth, and when added to â€Å"re†, makes â€Å"rebirth†. During this time of rebirth, many fields of work were being reintroduced. Most historians refer to this era as the revival of classical thinking and older art and architectural techniques, as well as a time of invention. Although the Renaissance expanded to the furthest reaches of Europe, Italy was the birthplace of this historical time period of revival. The main reason Italy was the starting point of this revolution was because of its large city states. At the time, Northern Italy was exceptionally urban, whereas the other parts of Europe, where the Renaissance later spread to, were more rural. Since these cities ha d such large populations, there was a chance for people to converse in public forums and exchange ideas. These ideas were thoughts like reintroducing the works of the Romans and Greeks. Many people in these urban cities shared this idea of creating new work based off of what the Romans and Greeks had previously constructed, because they did not like the art and literature created in the Middle Ages. This encouraged them to look further back in time and begin toShow MoreRelatedLogical Reasoning189930 Words   |  760 Pagesothers: not to worry; the relative importance of the principles will become clear as we go along.

Why was the civil war so long and so bloody - 1555 Words

Why was the civil war so long and so bloody? In 1860 the average American believed that they were living the happiest and luckiest a person could be. They were generally living better than their fathers, and looked forward to their children prospering more than themselves. However, at the time America had developed into two very different societies between the North and the South. These changing societies were beginning to adjust to the start of the industrial revolution in separate ways. In the North slavery had died out as it did not pay. However, in the South in had begun to prosper greatly. This was due to the invention of the cotton gin in 1793 which allowed large amounts of cotton to be raised using slave labour.
