Zinc and immunity - Research Paper Example iciency also manipulates development of the acquired immunity by averting the outgrowth along with some functions of T lymphocytes like production Th1 cytokine, activation and B lymphocyte aid.2 Similarly, development of B-lymphocyte and production of antibody, mainly immunoglobulin G, is tampered. The macrophage, which is an essential cell in most immunologic roles, is negatively affected by the zinc deficiency. It can deregulate cytokine production, intracellular killing, and phagocytosis. The impact of zinc on the main immunologic mediators is based in the myriad duties for zinc in essential cellular duties like RNA transcription, DNA replication, cell division, as well as cell activation. Zinc deficiency potentiates Apoptosis. Zinc as well acts as an antioxidant and is able to alleviate membranes.1-2 In people suffering from trivial zinc deficiency, the clinical signs are impaired smell and taste, depressed immunity, impairment of memory, onset of night blindness and reduced spermatogenesis in males.2 Rigorous zinc deficiency has the characteristics of frequent infections, rigorously depressed immune function, bullous pustular dermatitis, alopecia, diarrhea, and mental disturbances.3 Comparable effects of mild as well as rigorous zinc deficiency occur in laboratory animals that are zinc-deficient. An uncommon genetic disorder, called acrodermatitis enteropathica, happens in humans and cattle, resulting in reduced zinc absorption followed by attribute hyperpigmented skin lesions, deprived growth, and low concentrations of plasma zinc.2-3 This research investigates the features of zinc ecology of the immune system and tries to offer a biological foundation for the changed host opposition to infections seen in zinc deficiency as well as supplementation. Am J Clin Nutr 1998;68(suppl):447S–63S. Many human and animal studies show that zinc shortage reduces resistance to infectious diseases. Animals that are Zinc deficient have concealed immune responses. They

Stakeholder Essay Example | Topics and Well Written Essays - 500 words - 1

Stakeholder - Essay Example The inclusive definition includes any group or person who can be affected by the organization’s acts or who can affect the acts of an organization and now has expanded including non-humans too. The exclusive definition includes stakeholders that are focused on from the manager’s point of view such as the power of the stakeholder, the dependence of the institution on that stakeholder or even the risk from that particular stakeholder. The organizations that focus on the maximization of their wealth try to reduce and limit the quantity of stakeholders and try to aim on the financial measures. According to some writers, â€Å"stakeholders are recognized by the real or possible harms and gains that they will undergo or expect undergoing as a result of an organization’s activity or inactivity.† But such definitions are criticized due to the lack of specification and due to the challenges in recognizing the various stakeholders. Sometimes stakeholders are referred to as those people, who have the power to affect the institution, who the right of a relationship with the institution or have the importance to claim (Driscoll and Starik, 57). In present day’s nature is also being included in as one or more stakeholder(s) because of its importance not only to human life but also to the objectives, aims and intentions of a business o r a firm. As we previously studied that a stakeholder is an entity which gets affected by the acts or actions of an institution or has an effect on the acts or actions of an institution. Thus, nature has a lot of affects on the acts and actions of a firm and also gets affected to a very big extent by the acts and actions of a firm. Hence, nature and everything that comes in it hold the position of one or more stakeholder(s). But the fact that nature gets represented by social and ethical groups and by the various communities thus it many times does not gain the status of a stakeholder

Pioneer Electronics Essay Example for Free

Pioneer Electronics Essay In 1975 Pioneer maintained relationships with approximately 3,500 franchise retail outlets, the retail outlets benefited from a 5% Pioneer investment in local advertising, and attractive gross margins and credit terms. However, that same year, Pioneer and three competitors were forced to sign consent decrees with the U.S. Federal Trade Commission promising not to engage in alleged anti-fair competition practices – namely requiring distributors to use suggested list prices and punishing those distributors who didn’t comply either through delayed shipments or revoked franchises. A market price war followed the signing of the consent decrees, lowering franchise’s profits while increasing revenue for Pioneer. Pioneer followed with a new marketing strategy aimed at pushing its new lower-priced hi-fi components over compacts or consoles, this further boosted Pioneer’s profit, continuing to erode the franchise distributors’ profit margins. The final outcome was a select few distributors’ shifting from supporting Pioneer component sales to pushing competitors’ products in order to make a larger profit. Central Problem Pioneer Electronics must determine how to move forward from franchise distributors’ complaints that they cannot make an adequate profit selling Pioneer components over the lesser quality, more affordable competitors’ components. The result is â€Å"dissident behavior† by the distributors– including disparaging comments about the Pioneer brand to potential consumers, poor product placement in franchise stores and â€Å"bait and switch† sales tactics. These actions reflect a possible erosion of franchise distributor support, which might force Pioneer to alter its business model. Relevant Facts With the repeal of the fair-trade laws, the market changed drastically for Pioneer, sales and market share increased significantly during this period, prices and margins dropped. As the target market for their products expanded, Pioneer changed their marketing strategy to focus on selling mid-priced hi-fi products. Pioneer’s sales continued to climb, but this strategy squeezed the dealers’ margins even more and made it difficult for them to make a profit selling Pioneer products. Pioneer decision to reposition itself from a premium-priced brand into a â€Å"mid-priced, mainstream† brand affected the profit margins of its distributors negatively. At the same time, the company’s profit margin increased dramatically. Based on 1976 data from Exhibit 13, an average retailer profit margin was about 3.4%. Pioneer had a comparable profit margin of 3.9% in 1975, based on Exhibit 14 data. This margin increased by almost 3 times in 1976 to 9.4%. This clearly shows how Pioneer benefited from its market repositioning strategy while its distributors profits declined. Although surveys showed customers were very satisfied with Pioneer products, the sales force was unhappy and felt the lower margins were unacceptable. This drove a few dealers to speak disparagingly about Pioneer products and use bait and switch tactics to create profits for themselves. Mitchell knew the dealers’ support was critical to the current distribution chain, but he couldn’t go back to the old incentives. To continue to be profitable and adapt to the new electronics market, Pioneer reconsider its current distribution network. Alternative Courses of Action †¢Alternative #1 Shift distribution to department stores: Shift retail distribution from specialty stores to department stores and catalog showrooms. 75% of U.S. Pioneer’s sales were from hi-fi specialty stores, 5% by department stores, and 7% by catalog showrooms. Advantages: Extensive credit facilities, strong consumer â€Å"pull† advertising, and lower prices. Industry sources predicts a substantial increase in the market shares of department stores and catalog showrooms. Disadvantages: Department stores and catalog showrooms do not offer the extensive customer services provided by specialty stores, including professional sales assistance, demonstration, extended store warranty, on-the-premises repair, home delivery and installation, and loaner component programs. †¢Alternative #2 Multiple Branding U.S. Pioneer would offer several product lines of varying quality and price points under separate brand names. Different product lines would be carried by different types of retail outlets. The department-store line would be of lower quality and price than the signature line. Advantages: Multiple branding had been used successfully in other industries. It would enable U.S. Pioneer to adapt most effectively to future changes in retail distribution. Pioneer already sells compacts and car stereos to discount stores under the Centrex brand name. Disadvantages: This strategy could tarnish Pioneer’s reputation for selling only top-of-the-line products. Pioneer may have trouble keeping their distribution channels distinct, and therefore be incurring too much cost on the low end products or being destroying the brand value of the high end products. †¢Alternative #3 Company-owned Stores Another alternative is to operate its own retail stores. Some retailers in the low-fi market had been selling their own house brands for some time. House brands are starting to make in-roads in the hi-fi market and the specialty stores are carrying house brands in increasing numbers. Advantages: One way to protect Pioneer from the risk of large specialty store chains promoting house brands which would impact its sales. Disadvantages: A large initial fixed investment for starting up is required. The risk of expanding into a non-familiar territory which Pioneer does not have good expertise in. †¢Alternative #4 Dealer Communication improvement Dealer support is crucial for Pioneer growth. From Table A â€Å"Factors Influencing Purchase of Hi-fi Products† in the case, it clearly shows that dealer recommendations, advertising and store displays accounts for 42% of the factors influencing consumers decisions. The company needs to hire more salespeople to increase the frequency of dealer visits, provide higher cash rebates or other incentive programs and organizing yearly dealers’ conferences at different resorts. Pioneer needs to stop forcing its dealers to prominently display low-end components and push lower-priced components. Selling lower priced components affects the retailer’s profit margin. This results in placing higher sales emphasis on house brands or competitor products. Advantages: Retailer’s salespeople are the company’s point of contact with its customers. Happy and content dealers will push Pioneer product which will increase company’s sales. Disadvantage: The brand is what sells the product. The company should not waste funds on dealer rebates and conferences. This will result in a rebate war between different manufacturers. Plan of Action: Pioneer should pursue a multiple label branding strategy to capture sales in both the high end and lost cost market segments, which will increase total revenue and profits. The company is already implementing this through its Centrex brand name in Japan. This strategy will enable Pioneer, through the Centrex brand, to target the growing department stores market with its lower price product segment. The signature Pioneer brand can still be marketed through Hi-Fi specialty stores. Under this arrangement Pioneer will need to develop a customized sales and marketing plan for each brand and have separate sales and distribution channels. Pioneer will continue to contribute a percentage of sales to local marketing campaigns to assist local specialty retailers in maintaining local recognition within the community. The Centrex brand will be distributed through the larger department stores and because of the national recognition of these stores there would not be a need to contribute a percentage of sales to assist in local marketing. These funds should be used for other promotional items in the large department stores, such as contests for the largest sales in a month or quarter or number of a specific product sold. The company should also simultaneously invest in improving its working relationship with their dealers. The first thing that Pioneer will need to do is to cease printing ads in newspapers and/or journals to communicate to dealers about unapproved behavior. These types of conversations should be conducted behind closed doors, as neither side wins when they communicate in a public forum. Pioneer will need to begin to request their feedback and input on new market trends, consumer needs and product improvement suggestions and adjust the Pioneer products accordingly. Pioneer should implement the sales program from Exhibit 12 and shift some of the funds from the marketing campaigns to have local contests to spur sales among local sales force.

International Charter Of Human Essay -- essays research papers

International Declaration of Human Rights and Freedoms History   Ã‚  Ã‚  Ã‚  Ã‚  After the war crimes committed by the Germans in the holocaust that occurred during World War II, the United nations decided to create a document guaranteeing respect for human rights and fundamental freedoms for all people, regardless of race, sex, language, or religion. This document was called The Universal Declaration of Human Rights.   Ã‚  Ã‚  Ã‚  Ã‚  The declaration was voted in on December 10, 1948, which is now celebrated each year as Human Rights Day. The Declaration says that â€Å"all human beings are born free and equal† and establishes basic rights for all people and rules for the actions of governments in many areas pertaining to those rights. For example, it says that all people have the right to liberty, religious and political freedom, education, and economic well-being. It bans torture and states that all people have the right to participate in their governments.   Ã‚  Ã‚  Ã‚  Ã‚  The declaration is not a law, unfortunately, and in some cases has had little actual effect on the member countries of the UN. Governments with poor human rights records, such as China, do not agree with the UN’s attempts to promote human rights, saying that such actions interfere with their internal affairs.   Ã‚  Ã‚  Ã‚  Ã‚  The UN has a Commission on Human Rights. Its job is to monitor abuses of the declaration in member countries, hold international meetings on human rights issues and handle complaints about violations to the basic human rights.   Ã‚  Ã‚  Ã‚  Ã‚  It was in 1993 that the General Assembly created the position of High Commissioner for Human Rights. The commissioner job is to oversee all of the UN’s human rights programs, work to prevent human rights violations, and investigate human rights abuses. It is also in the commissioner’s power to publicize abuses to human rights taking place in any country. However most publicity about abuses to human rights does not come from the UN but from rival countries or non-governmental groups like Amnesty International   Ã‚  Ã‚  Ã‚  Ã‚  The UN has also written four international treaties on human rights. These treaties do have the force of law but are very hard to enforce. The treaties deal only with the problems of genocide, racial discrimination, civil and po... ...rights issues in the world. Before it was drafted, many cases involving human rights were simply ignored or kept quiet. Take for example just before World War Two, Nazi Germany was known to want to eliminate a great percentage of people not fitting into their â€Å"Aryan† master race, yet they still hosted the Olympics of 1936. At those Olympics they refused to grant a gold medal to a Jewish person, Jesse Owens, and still America and many other countries chose to ignore Germany for political reasons. After the war, almost in response to the declarations, various human rights organizations, such as amnesty international have been created. They almost always use the Declaration as their basic outline for the rights of human beings. These groups bring much attention to the human rights problems of the world. A good example was the later war in Vietnam, protests in the United States over unfair treatment of enemy civilians is one of the main reasons they were forced to pull ou t.   Ã‚  Ã‚  Ã‚  Ã‚  So in conclusion I must say that nobody can argue that forcing people to stand up and take notice is the only way to eliminate a problem and that is what the Declaration has achieved.

Solar Energy Essay -- Solar Energy Resources Essays

Solar Energy What do the bubonic plague in the 14th century, the influenza epidemic of the early 20th century and the spread of HIV/AIDS in the late 20th and early 21st centuries have in common? One answer, according to Joel B. Stronberg author of the American Solar Energy Society’s â€Å"Common Sense,† is that they have all been called pandemics. According to Merriam-Webster.com, a pandemic occurs over a wide geographic distribution and affects â€Å"an exceptionally high proportion of the population.† Joel B. Stronberg declares that we are currently facing another pandemic. This pandemic is the combination of the consequences of burning fossil fuels. The two major problems from burning fossil fuels are global warming and decreasing oil supplies. However, Joel notes that there is a difference between this pending pandemic and the pandemics previously mentioned. This pandemic can be prevented. Solar energy is a nondepletable resource that can help us avoid furthering global w arming and decrease our continued dependence on oil. Solar energy is, in the most rudimentary terms, energy from the sun. It can be converted into electricity and heat. Surprisingly, less than 0.1% of our heating, transportation and power energy come from direct sunlight. This is surprising because, according to www.johnbarrie.com, in one single second the sun gives off thirteen million times more energy than the amount of electricity used by the world in an entire year!

Eating and ‘preparing’ foods that require no art whatsoever in making

It is definitely true that our society has become accustomed to eating and ‘preparing' foods that require no art whatsoever in making. Canned goods and microwave products are rampant in today's everyday menu. The reason for this, I believe, lies in the characteristic of this generation of being unwilling to learn anything difficult or time-consuming. Art unquestionably comes from things that take time and require effort: sculptures that take weeks to finish, movies that take months to film and hundreds of people to accomplish, and poems that ask for concentration, time, and effort.People nowadays want to learn things quickly, finish objectives within eight hours, and forget about them in less time. They want their food delivered in less than half an hour. They want massages in under half an hour. In fact most of the services today can be taken out or delivered. Taking time and effort to learn, master, and perfect things are no longer of interest to most of us. To add on to this already non-conducive situation of quick surface learning, poverty fans the flame of the lost tradition of home cooking.Although a long and artful process of preparing food is ideal and very high-culture, most people simply do not have the luxury of cooking such fancy and multi-ingredient meals. Most of the population, classified as low income families, has to make do with meals that are simply fried and not really ‘cooked' as much as they are heated. These over-processed foods are quick to prepare and simple, such that they lower the costs of a family. The effect of this is very bad for our culture.The rich heritage of unique methods and ingredients of cooking are lost due to lack of motivation and lack of financial capability. I agree with this. There can be no doubt as to the reality of the slow dying of the tradition of cooking within a family. Most families share these throughout generations via the practice of cooking meals together and transferring their knowledge. How ever, due to the younger generations' lack of interest in anything artful and effortful such as cooking, this transference is being impeded and ultimately ended.Less and less people inherit their family's unique recipes and family dishes. Also it is clear that poverty does play a role in limiting a family's participation in cooking tradition. Baking for example is a very expensive activity and only those who have the luxury of eating pricey desserts engage in it. However, I believe that time also plays a role in the death of the cooking tradition. Families seem to hold less and less time together (another cultural issue altogether) and one of the first things that suffer from this is the time spent preparing, cooking, and eating dinner together.

Musical Texture essays

Musical Texture essays One unifying element between all the cultures in the world is the existence of music. From traditional western style orchestra to religious chanting of the Yanamomo people in Brazil, music can be heard from all corners of the world. Music is popular because it has no boundaries or fixed sound. Variety and freedom allows every person or culture to enjoy their own preference in music. Most cultures invent their own style to coincide with their daily life, type of work, religious beliefs, history, and traditions. The undefined texture of music allows for these differences. Texture allows for great variety and never ending invention of new sounds. The texture of a song can be thin with low, easy to follow sounds, or thick with several different instruments playing at different pitches or notes. A monophonic texture is the thin texture. It is easy to follow and only includes a single line of music. In monophonic texture only one person is playing an instrument, or the others playing are in the same octave and in unison. An example of monophonic texture can be as simple as a solo singer or a few singers harmonizing. Another example of monophonic texture is the beginning of Beethovens symphony number 5 in C minor, 1. Its dramatic pounding is easy to follow and is not confusing. It puts forth on emotion for the listeners to interpret. Another type of texture is polyphonic texture. This texture is thicker and involves two lines of music. The different instruments arent moving in unison and are competing for the attention. An example of polyphonic is a canon or round. Again Beethovens symphony number 5 in C minor, 1 displays this type of texture by repeating the same pounding but at different intervals. While listening one can concentrate on one particular instrument and hear in the background different instruments fighting to be heard. After the intense polyphoni ...
