Kant s Theory Of Rights - 929 Words

Kantian Justice Kant believed that humans beings are rational beings, worthy of dignity and respect. That the moral action does not consist on the consequences but instead in the intention of why the act was done. Its important to do what is right because it is right, and not for a personal motive. Kant does not believe in self-interest to be part of the moral worth. Self-interest such as wants, desires, and appetites are part of what he calls â€Å"motives of inclination†. He only believes that actions done by motive of duty have a moral worth. The differences between duty and inclination is that inclination involves personal interest, in other words that a person can get benefit by doing the right thing and not because the individual wants to do it. Duty motive involves individuals that do not get any personal benefit from their actions. (M.J Sandel, 2009) Kant’s theory of rights involves a strict logical deduction of the principle of justice from the moral law. The principle of justice must fix human rights that would make any government respect and enforce every individual autonomy. In Kant’s readings, â€Å"autonomy is the universal ethical ideal for all individuals, and its realization requires the political commitment to the legal protection of a set of ahistorical individual rights, most notably the right to external liberty† (Beck, G., 2006). Autonomy requires positively, obedience of the moral law. For Kant, autonomy is the end of every individual. Kant believes thatShow MoreRelatedThe Case Of Evan Motts Assisting His Wife s Euthanasia Essay1644 Words   |  7 PagesI am going to discuss in this essay the case of Evan Motts assisting his wife s euthanasia.

Types Of Type 1 Diabetes Mellitus - 1713 Words

Introduction: Type 1 Diabetes Mellitus is a disease that occurs when insulin-producing beta cells of the pancreas are damaged or are being destroyed (Mahan, Escott-Stump Raymond, 2012). The gradual destruction of the beta cells of the pancreas usually leads to complete insulin deficiency, which ultimately manifests itself in the following symptoms at clinical onset: â€Å"high blood glucose (hyperglycemia), frequent urination (polyuria), excessive thirst (polydipsia), and a significant amount of weight loss, dehydration, electrolyte disturbances and ketoacidosis†, requiring dependency of exogenous insulin in order to promote optimal glycemic control in order to prevent further more severe complications; such as, ketoacidosis, microvascular diseases, macrovascular diseases, neuropathy, or worse – Death (Mahan et al., 2012). Type 1 Diabetes Mellitus can result from two existing forms: 1. Immune-mediated diabetes Mellitus, which is characterized by autoimmune destruction of the beta c ells of the pancreas and an idiopathic (unknown cause) commonly seen in ethnic groups of African or Asian descent (Mahan et al., 2012). Of all diagnosed diabetes cases, prevalence of Type 1 Diabetes Mellitus accounts for 5%-10%, and although onset may present itself at any age, 70% of cases are diagnosed in young adults (younger than age 30), with a peak in occurring incidences seen mostly in children and adolescents (Mahan et al., 2012). â€Å"In the United States approximately 1 in every 400 to 500Show MoreRelatedApplication Of Type 1 Diabetes Mellitus3781 Words   |  16 PagesTable of Contents I.

Question: Demonstrate an understanding of the Concept of the Organisation and the Environment in which it operates, including determining the competitive advantage for an Organisation. Answer: Introduction The following paper concentrates on the different aspects related to the chosen organization GSM London. Many important things and issues related to this topic will have to be discussed here. The focus will be on the background of the organization, the industry or the sector, in which it operates the different aspects like the organizational operations and responsibilities, will have to be discussed as well. Certain issues that create a problem within the organization have to be identified and given an overview with some probable recommendations to solve it. The business environment of GSM London has to be discussed in the following sections of the paper. As GSM London is an organization related to the academic works, some ethical codes have to be maintained here as well. Therefore, it is necessary to discuss all the valuable things in relating to the organization itself. Company background The full name of this organization is Greenwich school of Management. This organization is located at Greenwich in South-East London (Gsmlondon.ac.uk, 2017). This operates as an independent school of higher education in the country. Another branch of this organization is situated in Greenford in West London. This organization deals with providing thousands of students many business-specific courses in the graduate and post-graduate courses. They also provide the students with many types of training courses and the students who are admitted here are mostly international students. The records say that more than 15000 students take education from this organization (Gsmlondon.ac.uk, 2017). The organization was founded in 1973 and the current CEO is Sir Bob Burgess. Headquarter of this organization is situated in Meridian House in Greenwich. They have worked in partnerships with the Plymouth University from the year 2006 and have delivered validated undergraduate degree awarded by Plymout h (Gsmlondon.ac.uk, 2017). They have a number of expert course advisors in the organization. Business environment The business environment of this organization is quite helpful and they have various courses to offer to their students (Brown and Carasso 2013). This organization serves the education sector in the country and one of the most reputed institutions as well. They offer financial advice from their expert finance advisors who advise the students about how they can manage their headaches about the funding of the fees for their courses. The organization looks to provide support to the students and they desire core academic skills for better future of the students. They provide a proper academic environment for the students that add to the success of the students on the long run (Brown and Carasso 2013) They also focus on the students individually to help them overcome their troubles in the understanding the courses. All of these plans and programs are looked after by the senior managers of the organization. They provide a simple business environment in the industry that helps the students to gather their knowledge properly (Brown and Carasso 2013) The business environment is quite competitive but the strategies they have undertaken lead them to gain the competitive advantage over their rival organizations (Botha, Kourie and Snyman 2014). One of their rivals in the industry is the University of Greenwich. The management and leadership styles being followed here are quite motivating. The management motivates the employees or the teachers and trainers greatly so that they give their best efforts in trying to solve the problems of the students. This training in GSM London helps them to get best jobs in the business industry with great placements (Mourshed, Farrell and Barton 2012). Various types of business environments are present that leaves an impact on the proceedings of the certain business industries. These are considered as the economic environment, political environment, social environment, legal environment and the technological environment (Pulver 2012). Economic environment The economic environment of the institution GSM London is quite stable. The institution helps in providing the students with scholarships and much other assistance (Wild, Wild and Han 2014). The institution helps the students get educational loans especially to the students who are from UK and other EU countries. The economic and fiscal policies of the government have long lasting impacts on their countries. The good training services and good placements in the industry help in the economic growth of the country as well as increasing the GDP of United Kingdom. It also helps in the foreign multinational companies being interested in investing in this country. Political environment The political environment of the United Kingdom is quite stable with the democratic environment (Wild, Wild and Han 2014). The attitude or approach of the government towards the educational institutions is quite motivating as the government is interested to create more job opportunities in the country by providing good education. The management of the organization is quite susceptible to the immediate changes in the government policies. Social environment The different social factors are responsible in determining the social environment of the business organizations. The social demographics of the area have a great impact on the success of the organization (Wild, Wild and Han 2014). The quality of life in UK is quite impressive with a good economic growth. This is why the families are keen to send their children to institutions where they can get the best education. The innovative strategies to incur knowledge into the minds of the students help them to get a strong hold in the industry. Their academic track record is quite good so they are very much in compliance with the social conditions. The literacy rates are quite high in the urban areas in UK so this again works as a positive criterion. The traditions in their good record of academic performance among the British give them an advantage over others (Wild, Wild and Han 2014). Legal environment The different laws related passed in the British parliament are obeyed by GSM London properly like the Equality Act 2010, Education Act 1996 and others. They do not discriminate any student due to their skin color or their caste. Equality id preserved in this organization all through (Wild, Wild and Han 2014). Technological environment Technology is an integral part of the modern day business. The GSM London has adopted the various technological tools to innovate new strategies of training the students and apply them in the practical field. This enhances the students skills (Wild, Wild and Han 2014). Effect of globalization on GSM London Globalization has a huge impact on the education sector all over the world. Due to the use of technology everywhere, GSM London has gained benefits. It has been able to make its strategy according to the global standards and being compliant to the industry (Rumford and Buhari 2012). They can post advertisements online through the use of social media and thus be able to attract more students from different countries. Their placement and track record have impressed the students. This attracts them to come to UK and study in GSM London by getting scholarships (Rumford and Buhari 2012). Consumer demand and its effects on business Consumer demand is a very important part in making business decisions. The consumers (in this case, the students) tend to find the best institutions that will cater to their needs and deliver their goals for their career (Gowrisankaran and Rysman 2012). They also find the kind of institutions that they can afford economically and get the best placements in the business industry. All these needs and requirements are fulfilled by GSM London. This is why they acquire a top spot in the business related education sector for their scholarships and well-planned training systems (Edwards, Sieminski and Zeldin 2014). Entrepreneurship, Creativity and Innovation GSM London is one of the most important institutions on UK who have led their paths for entrepreneurship in the education industry (Fayolle 2013). They have opted for expanding their business all over the world and get international students. They have the willingness to develop further and expand their services more. This way they are one of the pioneering institutions to adapt entrepreneurship. The strategic innovation like providing scholarships and financial advisors for their students has catered to gain competitive advantage through creative thinking power. The innovative training programs and using technology for better training methods have added to their success story (Khurshid and Ansari 2012). The creativity factor is well encouraged by the management of GSM London. Innovation process in GSM London is quite impressive. They use the different technological tools in order to attract their students (Lytton 2012). They also monitor the educational performance of the students by using technology. The different methods they use to improve the performance and thus achieving the faith of their students. Conclusion The paper can be concluded by saying that GSM London has provided bright career prospects to their students. The students who take part in the education programs are benefitted in a huge way by getting good jobs. They also provide scholarships that come as financial aid for the students. The students get quality training from the well qualified trainers and this helps them to enhance their skills. Good jobs earn them good salaries and thus make way for the economic growth of the country. Thus the entire country is benefitted by functionalist theory of sociology. People who get train them have a great amount of technological knowledge and they cater to the development of the organization. The entrepreneurship and innovative thinking leads them to become one of the leading organizations in UK education sector.

Whooping Chough Essays - Pertussis, Burkholderiales, RTT

Whooping Chough Whooping cough which is also known as Pertussis is caused by infection by the Bordetella Pertussis bacteria. It is a highly contagious bacterial disease that affects the respiratory system and produces spasms of coughing that usually end in a high-pitched whooping sound. In this report I will describe how Pertussis is spread, contracted, what treatments are available for it and the prognosis for the patient. I will also tell you about the many symptoms of the disease. Etiology: Pertussis is caused by Bordetella Pertussis the bacteria invades the nose and throat and then the trachea followed by the bronchial tubes of the lungs. People usually contract the bacteria through the air when an infected person coughs or sneezes. Then people inhale or come in contact with the infected saliva. People who have been immunized in the past may still develop infection but it is usually atypical or very mild that is another cause of whooping cough. The incubation period is usually about 7 days. Morphology & Diagnosis: Pertussis is a round shaped gram positive bacteria. Some of the symptoms of Pertussis include runny nose, coughing that may be dry or may produce sputum. Along with a fever usually 102F or lower. Severe coughing attacks that ends in a high-pitched crowing sound when inhaling or it will end in a high-pitched "whoop". The coughing spells may end in a momentary loss of consciousness and or vomiting. It also results in difficulty at breathing. It also can cause some people to have diarrhea. When some small infants have long spells of coughing they usually begin to cry which causes them to choke on there own tears. Pertussis can be treated by DtaP which is a vaccine that protects children against the disease. During epidemics, health care providers or others at risk may be advised to receive a booster dose of the vaccine. The immunization is not 100 percent effective and has slowly becomes less effective over the past few years. Some tests that can be performed to tell if a person has contracted are to take a culture of the secretions from the nose and mouth and throat. A complete blood count or CBC which measures the number of red blood cells and white blood cells in the blood. If there is an with an elevated number of white blood cell count characterized by large numbers of lymphocytes. There are also serologic tests for Pertussis. Treatment: The Treatments include Erythromycin which is an antibiotic that is administered and may shorten the duration of the symptoms. Infants under 18 months of age require constant supervision because breathing may temporarily stop during spells of sever coughing. Infants with severe cases should be hospitalized. An oxygen tent with high humidity may be used. Intravenous fluid may be given if coughing spells are severe enough to prevent enough fluid intake by mouth. Sedatives may also be prescribed for young children. Cough suppressants are usually not helpful and should not be used. Prognosis: The prognosis for a person who leaves Pertussis untreated in infants has a poor outcome. The disease has a one percent to 2 percent death rate. Death may occur from lack of oxygen to the brain and bronchopneumonia. Some other complications that may occur are slowed or stopped breathing, nose bleeds, pneumonia, convulsions which are caused by a lack of oxygen and can cause permanent brain damage. Some of the more serious effects are anoxic encephalopathy, cerebral hemorrhage, seizures and developmental retardation. Miscellaneous: In Ethiopia rural doctors give a vaccination for Pertussis to people in street markets in an effort to increase the immunity rate of their country. Pertussis has becomes an epidemic about every 2-4 years. It usually affects non-immunized children with a history of contact to the bacteria the most. Personal Reflection: Matts reflection: When I think of Whooping cough I don't think of it as a major epidemic. The reason why I believe this is because there is not much information on the subject and I had a very difficult time finding pictures of the bacteria and its effects. I suppose that if 10 out of every 100,000 people are infected with it then it must not be a very large problem. The disease doesn't to seem to have very sever side effects if it is left untreated. I am almost certain that in a few more years Whooping cough will disappear. Roberts reflection: My opinion is a little different than Matts but in some ways I feel the same. First off I do agree that in this
