Vaccines Essay Example | Topics and Well Written Essays - 750 words

Vaccines - Essay Example Vaccines stimulate the immune system of the body and helps it recognize the agent as a pathogen or foreign, hence destroying it (Bona and Bonilla, 1996). Vaccines do not offer complete protection of the body against a certain disease; therefore, it is important to choose the most adequate type of vaccine in order to make it more responsive. To develop an effective immune against a dangerous virus, one must consider important aspects, which include the rate of maintaining high immunizations even when the disease is rare. Other factors to be considered include the impact of the immunization campaign on the epidemiology of the disease in the long term and the continuous surveillance of the disease due to the introduction of the new vaccine. An inactivated whole organism vaccine is produced by the killing or destruction of a disease causing organism by use of radiation, heat or chemicals (Reiss, 2005). It has several advantages since it is very stable and safe, which is an advantage over live vaccines, since the inactivated vaccines are killed and cannot mutate back to form the disease causing agent. They are advantageous since they do not require refrigeration hence their storage and transportation is easy, which makes it accessible for people in developing countries. Inactivated vaccines also have the main disadvantage of triggering a weak immune system response; hence several boosters are needed where as live vaccines stimulate a stronger one. This is a major set back to people in areas that are inaccessible to healthcare due to lack of boosters. Another set back is that the nonantigenic portions of the vaccines microbe may cause an inflammatory response to some people. Attenuated whole organism vaccines are live vaccines that contain the living microbe or the modified live viruses which are only weakened in laboratories in order to prevent diseases (Goldsby et al 2000). Viruses are attenuated by growth of generations in cells where they do not reproduce so well , the unsuitable environment makes them repel the viruses. As they grow they become weak due to the new environment and their natural host. They are the closest thing to natural infections hence they are good to the immune system. They stimulate strong antibody and cellular responses, and give lifelong protection with one or two doses. They are easy to create for given diseases like chickenpox. There are several setbacks to this immune system, for example the attenuated vaccines are live so they may revert and cause disease, and people with weakened immune systems for example HIV-positive people cannot use attenuated vaccines for their own protection. Attenuated vaccines need to be refrigerated therefore it is hard to store and transport them to under developed areas. They are difficult to create for bacteria, since bacteria have so many genes, therefore, it is hard to control them. Recombinant vector vaccines are also known as sub-unit vaccines, and are comprised of antigens which elicit the immune system best combined with the DNA of another (Murphy, Walport and Travers, 2008). They are mainly used for complex infections, are experimental and are similar to DNA vaccines though they use bacteria to bring out DNA to the cells in the body. Vector means the virus or a bacterium that is used as the carrier virus latches on to the cell and injects genetic material into the cell. Scientists take the genomes of harmless viruses and insert the genetic material in portions into the cells. The viruses ferry the microbial DNA to the cells. The recombinant vector vaccines cause a natural infection and, therefore, stimulate the immune system. Attenuated bacteria also play the role of vectors, where the genetic mater

Health - Article Example Further complications associated with diabetes include kidney disease, blindness, and the threat of amputations. This health concern currently affects about 16 million people in the United States with an estimated five million of those unaware of their condition. African Americans face heightened risks of contracting diabetes. Although about 33 percent of people with the illness are unaware of their condition, nearly three million or almost 12 percent of the African American population over 20 years of age suffer with symptoms of diabetes.   Because of this, African Americans have been identified as being at greater risk than those of Anglo descent to suffer macro-vascular problems such as strokes and heart disease. â€Å"African Americans are 1.6 times more likely to have diabetes than non-Latino whites. Twenty-five percent of African Americans between the ages of 65 and 74 have diabetes† (American Diabetes Association, 2006). The immune system, the environment and genetics are factors that influence Type One diabetes but the risk factors are more clearly defined for Type Two diabetes. These include obesity, physical inactivity, elderly people, family history of diabetes, a past history of gestational diabetes and those with a weakened tolerance for glucose. Ethnicity is another risk factor. â⠂¬Å"African Americans, Hispanic/Latino Americans, American Indians, and some Asian Americans and Pacific Islanders are at particularly high risk for Type Two diabetes† (American Diabetes Association, 2006). Despite the biological impediments that cannot be altered, African Americans can take measures to combat this genetic predisposition. Those African American diabetics who are overweight when they begin the nutritional program may require more initial calories until their weight drops to a more normal level. The reasoning is that too rapid of a weight

Paul Ricoeur’s Philosophy and Theology. Essay Example for Free

Paul Ricoeur’s Philosophy and Theology. Essay Paul Ricoeur was born to a devout Protestant family and grew up with his aunt since he was two years of age. Because his mother died and his father was killed during the World War I, he grew up as an orphan in a small remuneration afforded to him by the government as a war orphan. He was a bookish and an exceptional student during his time; his family’s influence brought him up with Protestant faith. He studied philosophy at Sourbonne and got influence from Gabriel Marcel. During World War I, he served the French army in 1939, became prisoner of war in Germany for five years. During his stay at the camp, he met other intellectuals like Mikel Dufrenne and read a lot about Karl Jaspers who was to have a great influence on him. After the war, he continued his studies and in 1950, he received his doctorate degree. He was given opportunity to work as the Chair of General Philosophy in his alma mater in 1956; from there he began his work as a prolific writer sharing his philosophy and theology. Throughout his life, he was known and respected as one of the most impressive philosophers of the 20th century. Every event in his life has contributed to what he believed in. His Christian belief was influenced by his family; his philosophical view was influences of people he met, he talk, and read. He is a well-known Christian philosopher yet, his writings were appreciated by both non-Christian and Christian. Paul’s Ricoeur’s Philosophy Ricoeur’s philosophical is central to the meaning of life and self. Recoeur’s philosophy is based on the two questions about the self. These questions answers are about the identity of the self and how should it live. Recoeur viewed self hood as inter-subjective capacity for agency and self self-ascription, and anybody can acquire. It means that self as an agency, and self-ascription. However, in his exploration of the issue, he discussed the philosophical thinking in five aspects namely: hermeneutic philosophy, post-Hegelian-Kantian methodology, narrative theory, philosophy of the self, and a moral-political philosophy. Hermeneutics is defined as a system through which a certain belief is interpreted using a specific theory and method for interpretation. Paul’s hermeneutics philosophy according to Paul Ricceur and Richard Keamey is of twofold source of reflection: the hermeneutics of testimony and the hermeneutics of the self. In their explanation, Paul had come up with a thesis, which concludes that testimony must give something to be interpreted as in history, and this testimony will be the object of interpretation. The hermeneutics of self on the other hand pertains to the role in which attestation has to play. David Kaplan in his article explained that hermeneutics for Ricoeur is interpretation of knowledge through its signs, symbols, and texts; it is interpretation of human works and actions. The Post-Hegelian Kantian philosophy on the other hand, is mediation for Ricoeur in such a way that it is combining two different views. Ricoeur accepted Kant’s claim that ideas of morality and history is understandable, and that it has universal validity because of its theoretical and practical reasons. Hegel on the other hand, viewed evil in the world as the â€Å"cunning of reason† as helpful for man in realizing a reality. Thus, post-Hegelian Kantian means that expectation is a hope for a humanity belonging to a history, which as a whole is a collective singular. This vision of history is the foundation of ethics and laws in Kant. This implies that Ricoeur acknowledges the concept of totality as long as its scope of reflection is limited to universal rationality (or history). He is actually recognizing that any differences could be regarded as related as in plurality of voices (or idea) yet, reasons behind could be recognized when philosophy tries to find it. Ricoeur’s thesis in Time and Narrative presents that human experience and narration exist. Through hermeneutics, one can easily interpret human experience because it has narration or plot. Narration theory therefore, is telling, writing, and understanding of fictional stories, as Kaplan explained. Narration or plot according to Wall, Schweiker and Hall is an integration of philosophy of action and philosophy of language into a synthesis. By means of this integration, a production of narration is come alive through voluntary and involuntary human actions, its symbolic language, and conflicts, which are to be interpreted through hermeneutics methods linking the time and history. The Philosophy of Self or Philosophy of subjectivity is an attempt anyone can do to elucidate the meaning of man’s existence. Ricceur and Kearney explicate Ricoeur’s hermeneutics of self into the sovereign self and the destructive self. The sovereign self according to them represents the idea in its meaning in the modern philosophy, which pervades modern culture and develops the self-image of people in the modern society. The deconstructive self on the other hand presents self as pure extensionless, consciousness, already established in being. Self therefore has the capability of combining knowledge, and it is vulnerable for it seeks certainty and security. At this point, will and reason are very important to human for they are the instruments for self-preservation and self-advancement. Signs and symbols and human experience are essential for man to interpret the meaning of their existence. Moral Philosophy for Ricoeur emphasizes that human being is capable of affirming the limits of one’s own moral perspective and embracing God’s critical transformative power. Being a Bible believer, he believed that everyone has moral responsibility, which accounts directly to moral value. Wall Schweiker and Hall noted that these moral values could be deeply explored from distinctive theological and hermeneutical perspective as what Ricoeur tried to point out. The issue of moral thought or moral responsibility in the study of Ricoeur’s philosophy offers important remedy to present ethical situations or problems. Moral ethics is an expression of human capability though fallible man yet has the ability to embody moral values through the power of God by simply being humble enough to acknowledge weaknesses. Paul Ricoeur’s Theology According to Julisn F. Woods, Paul Recoeur approaches theology by asking questions such as: â€Å"Where is freedom? Or does le coincide with the discovery and understanding of an inner necessity deeper than choice and kind of autonomy? In a word, does the highest degree of freedom consist in the surging up of an absolute power of choosing or in the love fate? † These questions prelude Ricoeur’s ethical approach and hermeneutical approach to theology. Recoeur consider theology and philosophy to be distinct in terms of their contents. He sees theology as hermeneutical, which provides cross-disciplinary, cross-traditional conversational quest for truth. Recoeur was particularly interested in Biblical exegeses and has written an essay in collaboration with other New Testament scholars. He adopted Boltmanian tradition engaging in historical criticism while also affirming the breadth of Biblical genres. In the essay entitled â€Å"Ethics and Considerations on the Golden Rule† Recoeur cited that Christian Ethics or communal ethics in religious perspectives, as he calls it, consist in the tension between unilateral love and bilateral justice, and in mutual interpretation of each of these in terms of the other. According to Mark Wallace, Recoeur’s religious thought that as one attempts to interpret the Bible, it actually begins with the risk of understanding biblical language including symbols and signs. Recoeur himself stated that interpretation of the Bible should be in accordance with testimonies of the witnesses particularly the Jewish community. He regarded that the Christian message is meaningful and is worthy of consideration, and that examining it will it self very fully. For Ricoeur, the God of the Bible cannot be theoretically proven as a staple of reason or as a fact alongside other facts in our empirical experience. He believes that Gods existence cannot be proven by any natural theology that necessitates thought or the knowledge of empirical objects. Wallace pointed out that Recoeur relies on signs, not on proofs in interpretation of the language. Recoeur believed that pertaining to scripture language it relies on the signs and traces of a reality testified to at the horizon of philosophical reflection that demands to be interpreted and understood. In the argument of language interpretations, Ricoeur balances it against the possibility of error in the testimony of the witnessing community and regard it a risk that would result in false testimony. Wallace noted that the risk must be taken because the stakes are so high. Therefore, Ricoeur believed in the truthfulness of the Bible being the ultimate source of God’s words. Interpretation of it should undergo hermeneutical approach based on history by knowing underlying concepts suggested in symbols, signs and text. For Ricoeur, the stakes is the possibility of Biblical language being a faithful trace of God’s presence in the Jewish and Christian communities. He believed that the knowledge of the absolute is never given in an absolute sense but only relative to the contingent and fallible signs that the divine life gives of itself in its generosity. Ricoeur agreed that religion deals with man’s ultimate concern and that the New Testament calls to be Christ like, is the counterpart of the mandated self of the Hebrew Bible.

Reflection on a change management and leadership

Reflection on a change management and leadership In 1947, MIT Professor Harold E. Edgerton and his several students were established EG G and which were involved in management of nuclear weapons to government and also in a wide range of similar activities. Perkin-Elmer was an older company then EG G and was established in 1930. Perkin and Elmer introduced it in a partnership and its operation was divided into two major divisions which was Analytical Instruments Applied Bio system. In 1999, there was an acquisition of Perkin-Elmer and EG G. Perkin-Elmer sold its name and Analytical Instruments division to EG G and EG G also sold its technical services business to Carlyle group investment firm .Then they would drop the EG G name and take the name of the acquired co. by disappearing the hyphen between Perkin Elmer and after the approval of its shareholders then after EG G was known as PerkinElmer. But there was one problematic element in the future of EG G its Perkin-Elmer operations was a good leadership. A good leadership was required in EG G to change a company rapidly and radically. Thats why for the fulfillment of the above requirement. In 1998, GREGORY L SUMME brought in company. He was with the experienced a lot as a partner at Mc Kinsey Co. , at General Motors he was general manager of commercial motors, at AlliedSignals Aerospace Engines and at General Aviation Avionics he was a president and recently at the Automotive products Group at AlliedSignal he was president of it. And because of his this track record at making technology companies competitive and profitable the Co. brought him to turn around the business as in recent years the company had been faltering. Now, PerkinElmer divided its business in two segments Human health and Environmental health. In Human health they are dealing with the companies of Bio-discovery, Genetic Screening Medical Imaging operating units. Environmental health segments are dealing with the laboratory services, Analytical sciences and detection Illumination units. DISCUSSION OF CHANGE MANAGEMENT AND LEADERSHIP THEORIES Change management: Change management  is a structured advent to developing  individuals,  teams, and  organizations  from a current status to a desired future status. It is aimed at empowering the employees to secure and changes of the grip in their current business environment within the organizational process. In Change management, project changes are formally introduced and approved. Models of Change Management McKinsey 7S Model The McKinsey 7S model involves seven interdependent factors which are categorized as either hard or soft elements as. I personally feel that 7s model can be related to this assignment as the changes were distributed in 7 elements which are as above and which are explain below as per the related company STRATEGY: after the acquisition, the leader implemented new strategies in the company. STRUCTURE: there was a structural change because of acquisition. SYSTEMS: New systems were implemented by the new leader in a company. SHARED VALUES: there were some ethics and new systems of work made by new leader which was shared as a core value of company. STYLE: the style of leadership adopted by the new leader to sort out all the complicated issues of the company. STAFF: the employees were distributed according to their capabilities and mostly new staff was recruited. SKILLS: Training programs were given to every individual from top to lower level management. Leadership  is the process of  social esteem  in which one person can influences others to attain an objective and directs the organization with a group of people to achieve a common goal through change. Leader: An individual who has granted authority, usually based on hierarchal position, in an organization. Leaders carry out this process by applying their leadership knowledge and skills make it more cohesive and coherent. Leadership is ultimately about creating a way for people to contribute to making something extraordinary happen . According to this assignment I concluded that the contingency theories are applied as this theory focus on individuals related to the environment that can be determined which particular style of leadership is best satisfied with the situation. The organization was structured in a way that who reports to whom rule was adopted. All the implementations were covered by the leader Gregory L. Summe. He distributed the whole problems in his effective leadership style that he focused on identifying the situational variables to fit the particular circumstances. COMPLICATED ISSUES IN EG G They had problem like inconsistent operating performances, a week reputation with investors, a highly fragmented organization as a company was holding of 31 diverse businesses with 31 different cultures brands and many businesses with uncertain prospects, no strategic coherence while there was lot of good technology in the business, experienced executives were there in company management but some of them had a lack of the right skills, the Pace Priorities were incompatible with the direction of the co. want to go as many of them came from the govt. services business and also other managers skills were under-developed and too narrow. So, they worked in one role in one business of EG G for a long time. CHANGES ADOPTED TO OVERCOME Firstly, the company focuses on improving their ability to gain consistent earnings. So that, they had good financial record and also regain trust of financial markets. And for this they established a new culture which was with more ambitious about performing goals and with clearer accountability. Secondly, it consolidated its 31 businesses into five strategic business units. Five strategic business units Thirdly, they offset the charges involved in this restructuring from the sale of several businesses including two mechanical businesses Sealol and Rotron. Fourthly, they sold all the government services business as it operated in a low margin, consolidating, declining market. Fifthly, they changed their name to signal to their customers, investors and employee that this was a new company. Sixthly, as they started with nine different businesses and brands but then they quickly narrowed their focus on just three segments: specialty illumination, digital imaging and telecommunication as dealing in more selective and for healthier their portfolio. Seventhly, they made seven key acquisitions and this is designed to quickly provide them complementary products, technologies and geographic coverage. Seven key acquisitions are divided as follows: One in optoelectronics, One in fluid sciences, Two in instruments, and Three in life sciences. Eighthly, they shifted power away from corporate center to each of the business units. Last but not least, for all employees of PerkinElmers they place a broad range of training programs to teach leadership skills, business fundamentals and best practices and it consists of four programs aimed to develop each individual at various levels of the organization and they were Advanced Leadership Institute, Emerging Leaders Program, Driving World-class Performance Program and Skills based Training Programs. SUSTAINING CHANGE Companys operating margin which was less than 6% in 1997 exceeds to 11%. After focus on three segments, the market leaders in both specialty illumination and imaging segments, which together accounts for 80% of the divisions revenues. In telecommunications segment, they achieve an annual revenue growth rate of more than 100%.The seven acquisitions made them number one in world in explosives detection systems and one of the top three in analytical instruments. They also have good terms with their investors as they understand and support their strategy to upgrade the portfolio. They reduce their corporate staff from 140 people to 65 people after taking the decision of shifting power away from the corporate center to each of the business units. CONCLUSION It can be concluded that if you have the right person leading the charges, good thing always happen but the Important decision is to choose right person and also in this company they choose a right man at right time which no doubt benefitted the company a lot. In contrast of a company, the Gregory L Summe was taking almost all right decision to turn around the business as per the requirement of the company and it also gained a success by restricting it. As its operating margin was increased , its revenues was increased , the co. had a tag of no. one in world in explosives , detection systems and one of the top three in analytical instrument and in present in current year its revenue was gone up to 498.3 million. The major change was to change of the name of company i.e. from EG G to PerkinElmer. The change of the name was just the part of acquisition however it was also to attract the new group of investors in the company. The profit has been raised in current year and it has been concluded that 2010 may be a brighter year for the company. PerkinElmer is delivering world drive productivity, quality and accuracy. Although forward looking statements such as believes, plans, project intends are leased on managements current assumption and expectation. However, these should be assured that their expectation and assumption are proved to be accurate and profitable.

The Man I Killed in The Things They Carried  Ã‚   Much can be interpreted by what people write.   The great thing about interpretations is that different writings can be interpreted differently.   Just like in the writings by Tim O'Brien.   His book titled "The Things They Carried," is a very deep and touching collection of stories about the Vietnam War.   The book is written, as a whole under the title "The Things They Carried," but is a collection of many people’s experiences in this destructive war.   One story that is a touching and very intriguing is titled, "The Man I Killed."   If anyone knows anything about Vietnam it is that many lives where lost in this disastrous war.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   All through school students are taught the very top layer of the telling of this war.   Such as dates, places that the war took place, and straight statistics of the war.   The parts that are left out are the tragedies, and the permanent scars the war left.   Students are told about the number of deaths that occurred, but they are not told about the lives that were affected, or how disturbing the war r...

Ethics in an Academic Environment Essay

Teachers hold the power and responsibility for building the foundations of intellectually and morally great minds. Since people spend a large chunk of their class and their entire formative years in school, their position and contact with young children and adolescents allows they shape and mold what these young people’s potentials and capabilities. Teachers have the opportunity to influence and inspire the future generations. As such, it is imperative that teachers become rightful role models of ethics for their students. Karl Menninger believed that â€Å"What the teacher is, is more important than what he teaches† (cited in Hunter, 2006). Menninger’s statement stress that teachers should always be a good ethical example for their students to look up to and learn from. A teacher must show tact, tolerance and morally-charge decision-making; he or she has to refrain from preferring one student over the other and from demonstrating disrespect or irritation for any of his or her students (Hunter, 2006). In a nutshell, for a teacher to be an ethical one, he or she has to always depict professionalism. Teacher professionalism manifests as both an internal, personal practice and an explicit expression. Professionalism starts from the inside. A teacher needs to make a fundamental commitment to teaching and to all the people that his or her teaching will touch (Phelps, 2003). This commitment is actualized by a teacher’s shown competency in his or her field and his or her capacity for following the teachers’ manual or code of ethics. It is essential that teachers recognize that their accountability should lie first, foremost and only with the students they teach. Therefore, a teacher shows his or her professionalism in how he or she prepares and plans how he or she could impart knowledge to the students in best way possible. Apart from making sure students understand what he or she is teaching to them now will have a high, enduring quality and will have more than just academic significance to students’ lives. To motivate and help them give their best effort every single day and to every single student, Phelps (2003) believes that teachers ought to accept and embrace all the challenges and hardships the journey of educating and aiding the youth’s learning may possess. In doing so, teaching is elevated to more than just a job for teachers but a calling. Professionalism requires teachers to invest themselves physically, mentally and emotionally in the process of the student’s education. This act allows teachers to make personal connections with students. Personal connections, relationships and bonds with one’s students are generally positive and helpful qualities. However, heavy emotional investments can also pave the way for the loss of professionalism, for which personal sentiments were invested in the first place. Emotional investments and personal connections can destroy professionalism and lead to a bending of the credibility of teacher-student ethics when they become the main object of teacher-student relationships instead of one of its reinforcements. When a teacher forms personal opinions or connections with one or a few particular students, it leads to a closeness or familiarity that can affect a teacher’s ethical conduct and professionalism. Examples would be developing a romantic relationship with a student or creating a hierarchy of student’s value based on a personal favoritism. Apart from creating partialities in favor of a student, personal opinions could further cloud a teacher’s judgment and create bias against a student or certain students. In both aspects, the founding of personal opinion can seriously hamper a teacher’s potential to be at his or her most professional best. Teachers are therefore reminded to abide by the code of ethics and ensure the protection of the rights of students, each and every single student (University of Iowa [UI], 2008). Teachers are encouraged to build rapport and make students comfortable in their presence enough for the students to liberally and honestly participate and contribute to class discussions. However, teachers are responsible for ensuring that there is still a professional boundary between them and student to prevent their relationship from getting too casual (UI, 2008). Teachers should instill and model fairness for all students of all racial, ethnical and economic background. Overall, ethics between teachers and students depend on the level of professionalism the teacher has. Teachers’ positions or social roles emphasize respect for one’s profession and the people they encounter. Teachers should direct all of their efforts and prioritize above all how they have contributed to students’ learning and development. References Hunter, D. (2006, Oct. 18). Teacher’s ethics.
