Alcoholics and Liver Transplants

Cohen and Martin do not believe that someone that has induced this disease by alcohol abuse is no less deserving of a liver transplant than someone that takes care of their self. They support the moral argument by stating, â€Å"If alcoholics should be penalized because of their moral fault, then all others who are equally at fault in causing their own medical needs should be similarly penalized†. One of the medical arguments that the authors combat is that liver transplants performed on alcoholics have a lower success rate then non-alcoholics. Statistics are presented in the text to argue this notion which really strengthens this aspect of the argument. They also state that a candidate for any other procedure would not be excluded because of the risk of success rate. This argument rises and falls based on what side you’re on. One could assume that most people waiting for a liver, who have never had a drink in their life would be very reluctant to side with this argument. However, an alcoholic or recovering alcoholic that needed a liver would more than likely be behind this passage all the way. One of the weaknesses of this argument was the comparisons that were made with other procedures. A reason why a doctor may be reluctant to transplant a liver to an alcoholic is the scarcity of the organ itself so comparing it to another organ that may be more abundant is asinine. Overall, this argument was moderately effective for the aforementioned reasons but I do not personally agree with the sentiments of the authors.

International Business Management - Essay Example It would use it to provide insight into how the concept can be used and a critical example of how the theory can be invoked. In his book, Competitive Strategy, Porter identifies some important elements that are necessary for the attainment of competitive advantage. Porter stated that competitive advantage arises when a firm provides the highest level of value to consumers, and hence attract the highest prices from them. Porter argues that this can only be internalised if a firm identifies some external elements in the business environment and internalize them in order to form a strategy based on them. In order to attain competitive advantage, a business needs to examine the unique positions and capabilities of competitors and players in an industry. When this is done, a firm can identify a business strategy and after that, designs its functional systems. Industry analysis involves the examination of the key players and the key threats to a given firms quest to attain competitive advantage. This is done by examining five main forces of the industry. These elements are: Every industry exists to produce some kind of value to the wider society. The industry would always exist and there is some kind of balance and stability that comes up naturally as the industry thrives and grows. The risk of entry of potential competitors refers to the situation whereby some third party businesses can enter the industry and produce services that can change the dynamics. The risk of potential competitors entering a given industry is strongly related to the presence or absence of barriers in a given industry. If there are no barriers in the industry and new entrants can easily enter, and this would make the sector extremely problematic. This is because a firms competitive advantage can be easily threatened. However, if there are high barriers like high capital requirement and other regulations, then an

Mechanical Measurements - Essay Example This technique is also sensitive to extreme temperatures because it affects the transition of the luminescent molecules (Mantel 2005). The PSP material is also used to develop coat for self adhesive tape and decals. This approach is preferable as it’s quick and easy during experimentation. It’s also reduces the time consumed for surface preparation as well as cost minimization (Mantel 2005). Pressure sensitive paint technique is also used in wind tunnels for pressure management. Due to the ability of this technique to provide field management, it produces global surface maps with better resolutions. Producing high quality global surface maps however requires a clear understanding of the e internal mechanisms of the technique as well as the functions, properties and experimental setup (Sullivan & Liu 2004). This technique has been found to be easier, more accurate faster and cost effective as compared to the use of pressure ports and computational fluid dynamics for exte rnal pressure management. ... mage illustrates the parts of the pressure sensitive paint device The pressure sensitive paint is made up of luminescent molecules that are distributed in an oxygen permeable polymer binder. When the PSP is exposed to ultraviolet rays, it causes the luminescent molecules to gain a higher energy state. In this state the molecules can decay is several ways such as shifting the energy to the polymer binder, conflicting with the oxygen molecules on the PSP surface and discharging the light (Mantel 2005). The luminescent molecules are sensitive to oxygen molecules therefore when they collide with the oxygen molecules, they react to produce light. The produced light is inversely proportional to the amount of oxygen molecules available on the surface. Most of the collisions between the luminescent molecules and oxygen occur when the PSP is under a lot of pressure, therefore the amount of light emitted is inversely proportional to the pressure on the surface. Hence the pressure on the surfac e is easily calculated from the amount of light emitted. However, the challenge with the luminescent molecules transferring the energy to the polymer binder is that the energy transfer requires increase in temperature therefore causing the temperature on the PSP surface to rise (Mantel 2005). This affects the ability of the luminescent molecules to react with oxygen and could lead to release of inaccurate results. The effects of the temperature rise are slight because in most cases the temperature rises by a few degrees. The use of PSP could also be challenging because of the nature of experiments and high level of sensitivity.
