A descriptive overview of the vertebrate adaptive immune response to both intra and extra-cellular pathogens with explicit focus on T-cell B-cell collaboration and antibody response.
Abstract This paper covers the major pathways by which foreign antigens are identified and dealt with through the adaptive immune response which is paramount on B-cell and T-cell responses and interaction with one another in distinct pathways and steps. It includes several diagrams and their explanations of antigens, B-Cells, T-Cells, APC's and more and their interactions and processes they go through.
From the Paper "All immune responses involving T-cell B-cell collaborations follow distinct pathways of interactions and development. These very pathways of the adaptive immune response are almost entirely dependant on the cellular interaction of B- cells and T- cells with one another. It is within each stage of these pathways and the progression of an adaptive immune response that we will concern ourselves. The following is a condensed synopsis of the adaptive immune response and the cellular interactions that will be the emphasis of this paper. Within secondary lymph tissues foreign antigen is presented to naive B-cells via their surface immunoglobulins (Igs) receptors. The same antigen is also presented to naive T-cells at this time. This presentation and subsequent recognition of antigen by both types of cells results in and end product of proliferation and development of naive B-cells into plasma cells whose function is the production of soluble immunoglobulins (antibodies), and the differentiation and development of memory B-cells whose function is to respond to subsequent exposure to the same antigen. However, this pathway is not self-sufficient and requires the direct interaction of activated T-cells, specifically "helper" T-cells (Th2 cells) 1,9. It is these T-cells in conjunction with the antigen presenting B-cells that interact to produce a hormonal response to infection. These interactions activate Th2 cells that in turn promote B-cell activation both through T-cell secreted cytokines, (interlukeinI1-2, 4 and 5), and also through direct cell to cell contacts involving specific surface proteins and corresponding receptors and the signaling initiated by the binding of these proteins to one another."
Abstract This paper presents a history of B.F. Skinner's theory of behaviorism. The paper then contrasts Skinner's theory with Freud's theory and combines it with the interpersonal model to explain adolescent development.
From the Paper "The following research paper presents B.F. Skinner and the history of his behavior theory. Skinner's theory is contrasted with Freud's theory and combined with the interpersonal model to explain the development of adolescents and personality Skinner's theory is then applied to the mental health nursing field. Findings are applied to a black male child."
Abstract This paper is a biography on W.E.B. Du Bois. It deals with the Du Bois' importance and significance to American History. In this article, the writer focuses on Du Bois' public life. The writer also discusses Du Bois' idealogy and his ideas regarding civil rights.
From the Paper "According to David Levering Lewis in his book 'W.E.B. Du Bois The Fight for Equality and the American Century', William Edward Burghardt Du Bois was born in Massachusetts. Du Bois was graduated from Fisk University and Harvard University and studied two years at the University of Berlin. He was the first black American to receive the degree of doctor of philosophy from Harvard. Du Bois founded the Niagara Movement, a group of African-American leaders committed to an.. "

Abstract This paper discusses the influence of Booker T. Washington and W.E.B. Du Bois on the American civil rights movement. The author argues that their outlooks are still alive today in debates concerning issues such as racial and class injustice and the role of leadership in the African- American community. The paper gives a brief biography of each man and his respective philosophical outlook. The author highlights where Washington and Du Bois' philosophies diverged, and their ultimate impact on racial equality in America.
From the Paper "The dispute between Washington and Du Bois polarized the leaders into two distinct sides, Washington's conservative supporters and Du Bois' radical philosophy (Two). Du Bois' strategy of agitation and protest led directly into the Civil Rights movement of the 1950's and 1960's. Washington's philosophy is often associated with conservative African Americans such as Justice Clarence Thomas and the Nation of Islam (Two). "
Abstract This paper compares and contrasts two news programs on B.B.C. (British Broadcasting Corporation) radio: "PM" on Radio 4 and "Newsbeat" on Radio 1. The writer studies the concept of multichannel broadcasting. The writer also discusses how the B.B.C. news is packaged to suit various listeners.
From the Paper "The British Broadcasting Corporation (B.B.C.) is the United Kingdom's multi-channel broadcaster airing programs over television, radio and the Internet. As a publicly-funded broadcaster, the B.B.C. is what the United Kingdom listens to B.B.C. Radio has five major national stations, each with its own broadcast style. .."
Abstract In this marketing summary of the B-Mobile German expansion project, the company B-Mobile explored the option to expand into the overseas cellular phone market. The writer assesses the German market and its characteristics. It focuses on the key strengths and opportunities for this project along with the key weaknesses and threats. It includes two charts. One summarizes the pertinent demographic information for the German population and the other shows the statistics of Germany's economic indicators for 2001. After giving recommendations for the future, the writer concludes by suggesting that B-Mobile should seek to enter this market place but concentrate its first efforts on the untapped market of rental cell phones before entering the common market in a few years.
From the Paper "B-Mobile began manufacturing cellular phones in 1994, operating primarily in the United States. They have experienced better growth rates and outperformed their competition in many areas. The cellular phone market in the United States has experienced exponential growth in the past ten years. However this has led to the formation of many small companies and there are very few new areas for expansion. All of the major metropolitan areas have reached market saturation and the business is expected to remain steady, but the growth rate previously experienced is not sustainable and the prospects for new clients dwindle. In order to continue its previous growth rates B-Mobile is exploring the prospects of expanding into other countries".
Abstract This paper explains that, in 1924, J. Edgar Hoover took over the directorship of the previously corrupted F.B.I. and transformed the bureau from a small, corrupt, ineffective office to one of the world's most feared and powerful law enforcement agencies. The author points out that, if most Americans in the placid 1950s saw Hoover and the FBI as icons of efficiency and incorruptibility, the turbulent sixties nearly proved its undoing, beginning when possible F.B.I. failures surfaced in the wake of President John Kennedy's assassination and Hoover's responses to Martin Luther King Jr.'s criticism of the F.B.I.'s handling of civil rights matters. The paper states that, in Hoover's wake, directors are now limited to one ten-year term on the job, and the agency apparently has shied away from the political abuses of the past.
From the Paper "During the next six years, Hoover systematically continued to hone and refine the BI, conducting a variety of solid if publicity-challenged investigations. The killing of an agent by a suspected car thief in 1929 brought headlines but little real change. The unarmed agent was gunned down when he approached the gun-wielding suspect, but agents would remain unarmed and without the authority to make an arrest - they were investigators, not officers - for several more years.
Hoover's special status was greatly enhanced when he first gained direct access to the president during the administration of his namesake, Herbert Hoover, no relation, between 1929 and 1933."
Abstract This paper reviews the life and history of Mark Antony, born Marcus Antonius. The paper discusses how, thanks to the works of famous writers like Plutarch and Shakespeare, Mark Antony has become a legend. The paper further discusses how his actions following Julius Caesar's death in 44 B.C. and his exploits with Queen Cleopatra have made him interesting reading and a source of entertainment for centuries. However, behind the many stories, there was a man who was a brave general, loyal supporter, dedicated Roman and ardent lover.
From the Paper "While Caesar was fighting in Egypt and Africa to defeat the last of Pompey's forces, Antonius was given the distinction of being made Master of the Horse (fact). His role was to be a politician and administrator in Italy while Caesar was out of the country. Unfortunately for him, Antonius was not good in that role and was removed in 47 B.C. and even banished from Caesar's sight for two years (unrv). Nevertheless, Antonius was able to work his way back into Caesar's circle; in 44 B.C. he was the one to offer the crown to Caesar, a circumstance much celebrated in the first act of Shakespeare's play, Julius Caesar (unrv)."

From the Paper "Given the above, it is clear that people can experience essential nutrient deficiencies even when they are consuming the recommended daily allowances. While it remains vitally important to prevent such vitamin deficiency syndromes, there is a paucity of scientific evidence that additional intake levels that exceed the recommendations set out in Table 3 above of protein or micronutrients in supplement form is able to enhance athletic performance, notwithstanding the claims of manufacturers to the contrary (Chee et al., 2001). These authors caution that these supplements can actually interfere with the metabolism of the vitamin B complexes, thereby making matters worse instead of better. "In fact, isolated amino acid supplements may impair the uptake and utilization of other essential amino acids from diet, and vitamins and minerals (particularly fat soluble vitamins) may be toxic in high doses. The most common deficiency states in elderly persons related to exercise and functional capacity are energy, protein, potassium, magnesium, vitamin B12, and vitamin D" (Chee et al., 2001, p. 194)."
Abstract This paper looks at the B-2 Stealth Bomber program which is funded by Congress and supported by different administrations. The B-2 Bomber is noted for its use of stealth technology, which makes it virtually invisible to radar as a means of detecting its presence. It examines how critics have pointed out a number of flaws in this technology and in the entire program together with a report from the General Accounting Office in 1998 was especially critical and generated a response from the Air Force in an attempt to counter the critics. It shows how an evaluation of the project suggests that while the technology could be useful, it is not yet sufficiently developed to be utilized at the level the Air Force would like and the costs would support.
From the Paper "The B-2 bomber might be useful in certain situations, but the number that are already in operation could suffice for such operations. The Pentagon originally stated that it needed only 20 B-2s for all purposes, and it has more than that now. The manufacturer claims it can make the bombers less expensively, but this does not mean they are needed (Thompson 41). While high cost might be a consideration in determining whether such a system is needed or not, the primary rationales should be need and effectiveness. In the case of the B-2, not only is it expensive, it is also probably not needed and does not work as advertised in any case. Given that there is no evidence at all that the bombers can be fixed or that they will suddenly become needed, the program should be ended. Even if there were such evidence, the costs might not be justified by the small return that would be achieved."
Abstract This essay is a case study that pertains to utilitarian and rights-oriented ethics in international business. The ethical issue involves the known environment in which H.B Fuller operates, in Honduras and Guatemala, when selling toluene-based glue that is in high demand in Central America but is as it is also known to be abused by street children to their great detriment. This essay argues that when this situation is examined from a number of points of view, an ethical position that is to the benefit of all players, including the H.B.Fuller organization, can be established.
Abstract This paper describes both Type A and Type B personalities, as well as the different categories of Type A personalities, and compares their characteristics to see which one most contributes to a working environment. The paper also explains how a manager can best balance the different elements of Type A and Type B personalities in the work force.
From the Paper "Imagine this scenario. It's a critical time during a particular business deal. The entire management "team" of one company reconvenes for lunch in an isolated conference room to discuss what has just transpired with the representatives from the other company over the course of the morning. One individual slams the door angrily behind him. With many an explicative, he sits down, complaining about the behavior and unfair tactics of the other negotiators. Another individual attempts to calm the raging man down. He waves off the succoring individual with an angry shrug, refusing to be calm and continuing to shout."
Abstract This paper shows that the character, Mr. B, is an example of Samuel Richardson's ideal reader. He is educated by reading Pamela's letters and journal in the same way that Richardson would have his readers learn through his novel. The paper shows that, by the end, Mr. B is the ideal model of a reader's transformation through reading the novel.
From the Paper "In his novel Pamela, Richardson attempts to educate his readers on morality and the value of virtue. He writes the novel to initially appear as a seduction story which would entice his readers but he is actually teaching a moral lesson in which he wants the idea of being virtuous to be as appealing as the vice expected from the seduction. Mr. B is the typical immoral seducer who is reformed throughout the course of the novel by reading Pamela's letters and journal. He becomes Richardson's ideal reader or model of a reader because he is educated and converted by reading Pamela's description of his actions and her beliefs."
Abstract This paper constructively analyses the philosophies of African-American leader Marcus Mosiah Garvey and his Universal Negro Improvement Association (UNIA), to that of W.E.B Dubois and his National Association for the Advancement of Colored People (NAACP). It looks at how Marcus Mosiah Garvey had fierce militant philosophies while W.E.B Dubois took more of a passive attitude.
From the Paper "Du Bois and the Niagara Movement did not last very long. They could not get a mass group of African Americans to follow and support their agenda. After the fall of the Niagara Movement, Du Bois joined the NAACP (National Association for the Advancement of Colored Peopled). Members of the NAACP were from various backgrounds. There were African American members, white members, and even Jewish members. Unlike the UNIA, the main focus of Du Bois and the NAACP was to formulate plans on providing legal enforcement for African American Constitutional Rights. "
Abstract "This paper analyzes the clothing brand Oshkosh B'Gosh and related products from the same company. The writer notes that the company has a good reputation, especially for its children's clothing line. Further, the writer points out that the name Oshkosh B'Gosh has a juvenile lilt that sets the brand in the minds of parents, though a more recent effort to extend the brand to adult clothing failed.
From the Paper "The brand name Oshkosh B'Gosh extends back to the start of the company in 1895, though the focus of the company has changed since that time. Founded in 1895 in Oshkosh, Wisconsin, Oshkosh B'Gosh, Inc. has grown from a small-town manufacturer of adult work wear into a global marketer of children's clothing and accessories. Best known for its rugged, men's hickory-striped bib overalls, The Company began making the pint size version in the early 1900's, so that children could dress like their fathers."
