HIV/AIDS patients in Zambia; Are they cared for? Essay
Executive summary Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) pandemic has created terrible burden for millions of individuals, families and communities worldwide. All sorts of exertions have been tried to curtail this tormentor and yet no known cure or vaccines have been discovered to prevent it. Religious prayers and even rituals have also seemed futile. However, the only option now is to only provide tender care, love and even nurture for those that are infected and consequently affected. This might prevent further spread and in turn minimise further impacts. This study seeks to improve on the care that should be rendered to HIV/AIDS patients and even strategize on how to improve the well-being of these ill-fated people. This study is a combination of situational analysis through a scientific study to understand various dynamics of management of HIV/AIDS patients in Zambia accompanied by formulation of strategies based on findings of the study. Background The HIV/AIDS prevalence rate in Zambia has even become one of the highest in the world. The prevalence rate in the general population is estimated to be 14.3 per cent with approximately 930, 000 people living with HIV/AIDS. Generally, despite all the campaigns, the stigma associated with HIV/AIDS still exists. On one hand, patients who are infected and have all the symptoms claim to be neglected at the hospitals and are not given the best services. It may not be out of order to query whether these health care providers are really taking care of HIV/AIDS patients. Several interventions have been staked so far but they do not seem to adequately address and even assess if HIV/AIDS patients are fully attended to by health care providers. For example, though not very successful, the National HIV/AIDS/STI/TB intervention strategy plan 2002ââ¬â2005 was developed with providing care to people living and affected by HIV/AIDS as one of the strategies of reducing the spread of AIDS. This research endeavours to provide a fundamental overview of how best the society at large can prevent further spread of HIV through care. This is deemed necessary for the implementation of an HIV/AIDS free management policies. If it comes out necessary to quarantine HIV patients, we will not hesitate to articulate that. Rationale This study aims at creating space for all people living with HIV/AIDS in different settings; especially in hospital environment, where most of them seek medical advice. This study shall improvise core framework for any change/s at the institutional and individual levels and across all sectors that in turn shall help create an environment of understanding, empathy, love, trust, hope, human rights and dignity for those most in need, that is, HIV/AIDS patients. Problem The major problem is the increased levels of stigmatization, discrimination and violation of human rights of HIV/AIDS patients in various settings. Minor problems include: * Lack of better strategies to deal with matters of HIV/AIDS * Lack of consistency in delivery of health care * Lack of friendly or social relationship between HIV/AIDS patients and care takers Objectives In addressing the problems stated above, the following specific research objectives have to be achieved: i. To investigate the extent to which patients are cared for by health care providers and relations. ii. To investigate the nutritional well-being of HIV/AIDS patients. iii. To identify factors leading to stigma, discrimination and human rights violation of HIV/AIDS patients. iv. To frame recommendations/strategies for policy makers and other influential groups for improvements in social well-being of HIV/AIDS patients. Methodology Participants Our sample size is 150 and these consist of all HIV/AIDS patients in the selected hospitals within Lusaka. The number of patients to approach per hospital will be determined on the total number of admitted patients at the time of data collection. Our target population is all HIV/AIDS patients that have been admitted to the selected hospitals for at least one week. However, since it will be impossible to survey all HIV/AIDS patients in all hospitals in the City of Lusaka, our study population will be patients admitted to University Teaching Hospital (UTH) and Levy Mwanawasa General Hospital. These patients are to be found on weekdays/weekends during the stipulated visiting hours per hospital. Data Analysis Data will be entered in excel and analysed using SPSS version 16 and descriptive statistics will be computed using the same software. SPSS will be selected because it is user friendly. Research Method Our research method is to perform a situational analysis study using a questionnaire capturing the HIV/AIDS patientsââ¬â¢ nutritional status, social relationship with care takers and how often they are visited by their relations. The questionnaire is as simple as possible to avoid frustrating the patients. Our sampling method will be convenience sampling where we would simply visit HIV/AIDS patients in hospitals under study. Convenience sampling will be used because this method would not impose a huge cost. Due to confidentiality and ethical considerations, the then main clinicians during data collection, at the hospitals under study will help to distribute questionnaires to those HIV/AIDS patients willing to participate. Currently, at UTH, we have Dr Nyirenda and Dr Musonda who are willing to administer the questionnaires in clinic five of UTH and Dr Alfred at Levy Mwanawasa General Hospital. We will simply approach any HIV/AIDS patient and ask them to volunteer in our survey. We will conduct an in-person survey by briefly introducing to them the purpose of our survey and explain why their participation will be valuable to the public. We will ask them if they have 3 minutes to do our survey. By having given them a brief introduction before we interview them, we can have a better sense of whether or not our survey is applicable to them. All non-HIV/AIDS patients in the stated hospitals will be ineligible to participate in the survey. In addition, a focus group will also be used to discuss the perceived prejudices that HIV/AIDS patients face. We will simply ask two HIV/AIDS patients, one representative from UNZA HIV/AIDS response office and one representative from the Ministry of Health to volunteer to give us one hour on one evening to get their opinions about the current levels of stigmatization, discrimination and violation of human rights of people living with HIV/AIDS. A facilitator will be present to conduct the group discussion and ask several open-ended questions while another representative will record the respondentsââ¬â¢ answers during the discussion. The advantage of this focus group study is that it is not costly, not time consuming and we can get in-depth information and opinions from people who are directly and frequently affected by the problem. Anticipated Results Expected Outcomes: Mounting evidence suggests that no known cure for HIV/AIDS has been unearthed so far. This simply entails that we can only reduce further spread of the pandemic by improving the lives of the people who are infected and affected by the pandemic. Consequently, this study will not only enlighten the policy makers on the real strategy of reducing the further spread of HIV/AIDS but also propose measures that may deal with the problem more effectively. It is further expected that this study will generate a research report and a fact sheet on the dynamics and impact of stigmatization and discrimination on those infected and affected by HIV/AIDS in Zambia. In the final analysis, it is expected that Government through the Ministry of Health and indeed the donors will be better informed, and could adopt some of the findings and recommendations in their policies. Impact: Results from this study are expected to feed into policies aimed at improving the well-being of HIV/AIDS patients in the country. From these, it is expected that the policies can be inferred to other countries facing HIV/AIDS. Utilisation: It is expected that findings from this study will be utilised by policy makers and implementers to enhance health care planning and ensure that the scarce national resources are allocated efficiently on projects that give the highest social and economic returns to HIV/AIDS patients. Dissemination Findings from this study will be disseminated through workshops that will be held so that all the stakeholders are informed about the viability of report findings as a remedial measure to the spread of HIV/AIDS in Zambia. Lastly, the study report will be available on the UNZA website and at UNZA HIV/AIDS response office for all to read.
I Am Mirror: A Historical Critique Essay
Claribel Alegr? a in Nicaragua in 1924 and a year later her family was exiled to El Salvador because of her fatherââ¬â¢s support of Nicaraguan guerrilla leader Augusto Cesar Sandino, Alegriaââ¬â¢s family was forced into exile by Anastasio Somoza, a Nicaraguan politician who later became commander-in-chief of the Nicaraguan army and eventually the nationââ¬â¢s president. Her poem I am Mirror was translated in 1978. And is the topic for this critique. In 1978 Alegr? a would be in the United States she left El Salvador in 1943 to study at George Washington University. From 1924 to her departure to the United States there was much violence in her home country in 1932 there was a massacre in which over a period of eight days thirty thousand peasants were estimated to be slaughtered by the vastly superiorly armed El Salvador army. The country also has vast disparity of wealth with one half to one percent controlling ninety percent of the nationââ¬â¢s wealth. The poem states: Water sparkles on my skin and I donââ¬â¢t feel it water streams down my back I donââ¬â¢t feel it I rub myself with a towelà I pinch myself in the arm I donââ¬â¢t feel frightened I look at myself in the mirror she also pricks herself I begin to get dressed This is identifying that wealthy portion of the population that controls 90 percent of the countryââ¬â¢s wealth. It is describing their lack of humanity to allow the rest of the population to suffer in great poverty. The author uses this lack of feeling to question if their humanity has been lost. Given that Claribel was able to afford an American education like many of the wealthy amilies did it stands to wonder how much she associated herself with the wealthy. Perhaps itââ¬â¢s contributed by her support for non-violence and the poor given that she did come from some resemblance of wealth herself. In the following stanza it gives evidence that the character of the poem was wealthy: I wander through the streets: children with dirty faces ask me for charity The children could be desperate enough to be asking anyone but the character given that they were doing better than most at the time. But then again it does say paint a pretty desperate picture with ââ¬Å"child prostitutionâ⬠and ââ¬Å"shouts like lightning boltsâ⬠Military enforced oppression was the times. The use of a mirror as a metaphor could also be alluding to the killing of one and wounding of five students protesting the government spending of one million dollars to bring the Miss Universe pageant to El Salvador. Of course during the program all that was shown were the beautiful sandy beaches and failed to show the massive poverty or military security around the contest. This is a portion from the poem: ââ¬Å"I am a blank mirror that nothing penetrates my surface is hard is brilliant is polished I became a mirror and I am fleshless scarcely preserving a vague memory of pain. â⬠This demonstrates how the government oppression and the atrocities resulting from the oppressive military rule were covered up by the government. Going back to the massacre of 1932 the government swiftly removed all accounts of the event from the libraries and replaced them with more favorable accounts. It was the way of life in El Salvador. The poor see much of the same everywhere they go poor. While rich control so much of the wealth they can afford to shield themselves from it. And the atrocities they never happened because the government says they didnââ¬â¢t. As it says in the poem: I simply reflect what happens at my side the tanks are not tanks nor are the shouts shouts The above demonstrates the denial that the people have even goes as far to describe them as ââ¬Å"phantomsâ⬠with how they do nothing to change. Which leads me to one of my favorite lines ââ¬Å"I hurt, therefore I existâ⬠which is likely an adaptation of Descartesââ¬â¢s ââ¬Å"I think therefore I am. â⬠In this situation she is saying that the lack of humanity of those who are the oppressors have stripped them from their existence. Furthermore as you read the poem it seems as if the character is coming to an epiphany but then recedes back right after the stanza ââ¬Å"I think, therefore I exist. â⬠This is probably used to show how permanent the stories last in the media how quickly something like the killing of the student protester outside of the Mrs.à Universe can become a national headline and then slip from the attention of any news outlet. The symbolism of a mirror is also further represented with how a mirror project a current image but does not contain any of its past. In 1979 a year after this poem was translated and Alegr? a was awarded the Casa de las Americas poetry prize for Sobrevivo. It is also the same year that the National Liberation overthrew the Somoza government. She continues to write about El Salvador and Nicaragua politics and resides in El Salvador, Spain and Nicaragua.

Compassion Fatigue Essay
The idea of caring for others is the motivating reason that draws most people into nursing. The concept of being a supportive part of a personââ¬â¢s health care needs is exactly the cause of compassion fatigue. Compassion fatigue can hit the best of nurses. Nurses who are highly driven and detail oriented are at a higher risk for developing compassion fatigue. Compassion fatigue was a term first applied in 1992; it is described as a syndrome that occurs in nurses when caring for a patient facing life-altering or life-threatening changes resulting from an illness. Compassion fatigue is prevalent among nurses today, due to increasing patient loads, as a result of nurse shortages and hospital cut backs. Compassion fatigue in nursing should not be ignored. There are classic warning signs that someone might be experiencing compassion fatigue. Recognizing the signs of compassion fatigue and following the necessary steps to prevent and treat it can provide one with the tools needed to make their nursing career rewarding. Warning signs of five concepts of compassion fatigue An essential first step in developing a prevention plan is to recognize the warning signs of compassion fatigue. Learning to become aware of the problem is the first step in prevention. Compassion fatigue cuts you off from the people that need you the most. Warning signs of compassion fatigue can include cognitive, emotional, behavioral, spiritual, and somatic symptoms (Portnoy, D. 2011). Cognitive Nature of the Problems and their Causes Cognitive behavior is the ability to judge and reason effectively and having a perception of your surroundings. Cognitive symptoms can include a decreased sense of personal satisfaction and personal accomplishments. A feeling of indifference or apathetic with ones patients is another sign. Aà sense of disorientation with lowered levels of concentration can also be seen during this phase. Emotional Nature of the Problems and their Causes Our emotions are a valuable source upon which we can rely on. Our emotions help us make decisions, and communicate with our patients. When experiencing compassion fatigue our emotional health suffers. Emotional signs that one might be experiencing compassion fatigue could include powerlessness, anxiety, guilt, anger, numbness, fear, helplessness, sadness, depression, shock, blunted or enhanced affect (Portnoy, D., 2011). Behavioral Nature of the Problems and their Causes Behavior is simply the way we react to a given situation. In regards to nursing, behavior is the skills and ability to care for our patients. Behavioral symptoms of compassion fatigue usually manifest in behaviors that are out of the ordinary for the person. Some examples might include irritability, being withdrawn from family, friends and co-workers, moody, appetite changes, unable to get adequate sleep, and isolating oneââ¬â¢s self (Portnoy, D., 2011). Spiritual Nature of the Problems and their Causes Spirituality can be described as a personââ¬â¢s way of being, thinking, choosing, and acting in the world in light of that personââ¬â¢s ultimate values(Barlow, 2006). Spiritual compassion fatigue can cause a person to question the meaning of life, or experience feelings of hopelessness. They might also question their relationship with God, or their religious belief system. Often times they will stop attending the church that they once faithfully attended. Somatic Nature of the Problems and their Causes The somatic system deals with our bodies. The somatic system is responsible for nearly all voluntary muscle movement as well as for processing sensory information. When compassion fatigue affects our somatic system we can experience physical symptoms such as, sweating, rapid heartbeat, breathing difficulties, aches and pains. Frequent headaches and colds can also develop during this phase (Portnoy, D., 2011). Physical, emotional, and spiritual needs of the caregiver Examining the progression of compassion fatigue and its symptoms, one thing is important to understand, compassion fatigue can have a major impact on a nurses professional career. It is easy to see that some of the symptoms can impair the ability of the nurse to provide quality nursing care to their patients. The best defense against compassion fatigue is for healthcare workers to take a proactive approach to their physical, emotional, and spiritual care. Physical needs of Caregiver The first step in the providing for the needs of caregiver is for the caregiver to recognize the symptoms of compassion fatigue. Healthcare workers should develop an improved sense of self-care. Healthcare workers, nurses in general spend their professional life taking care of others. Nurses should take care of their selves first. They need to develop a healthier lifestyle, by getting regular sleep, eating a balanced diet, and exercising regularly. Emotional needs of Caregiver Nurses who are young, idealistic, and highly motivated tend to suffer from compassion fatigue at a higher risk (Bush, N., 2009). Talking to friends, peers, and family to gain ideas on how to better balance your job responsibilities with your personal life is one area of focus for the healthcare worker. Learning to set boundaries in the early stages of your career can be a valuable tool. Recognizing your limitations is important; you cannot stop all the suffering and pain of all your patients. Learning that you can be there to help your patients without needing to fix everything can lessen the emotional toll that dealing with difficult situations presents. Spiritual needs of Caregiver Caregivers need to prepare their minds, bodies, souls, and spirits to become resilient in working with patient at intense levels (Bush, N., 2009). Caregivers need to develop skills of empathy when dealing with patients. A positive belief system and attitude can prevent feelings of hopelessness.à Caregivers should recharge their selves by making a list of enjoyable things that they find pleasure in. Remembering how inspired and motived they felt during those early days after graduation can help to refocus their thoughts in a more positive manner. Coping strategies and resources Applying a systemic approach to the prevention of compassion fatigue can provide the healthcare worker with valuable tools in the prevention of compassion fatigue. Awareness of what situations contribute to your stress level, what events cause an increase in your stress. Develop a health balance in your life. Provide yourself the opportunity to enjoy your favorite activities on regular bases. Learn to connect with friends, co-workers, and family to develop a positive support system in order to talk out your stress by sharing your thoughts and reactions to certain situations. Conclusion Realizing that you have control over how you manage your life. Being compassionate is not a character flaw; on the contrary, it is a great gift. The healthcare profession is a very demanding career. The ability to serve others is one of the highest callings that a person can have, but in order to do this effectively you must first take care of yourself. Understanding the key symptoms of compassion fatigue will allow for caregivers to put into place the necessary tools in order to prevent compassion fatigue. Engaging in self-care strategies will be beneficial for healthcare workers in order to handle to day to day stressors of their profession. References barlow828. (Nov 28, ââ¬â¢11).

Legal Structure of EC Law Case Study Example | Topics and Well Written Essays - 1500 words
Legal Structure of EC Law - Case Study Example Christina runs a graphic design business based in Brighton and ordered a new computer system on 5th July 2007 from Avalon Computers Ltd., a mail-order firm specialising in computer equipment designed for professional graphics use and based in Reading. Christina paid 3,000 in full for the equipment and it was delivered to her studio a few days later. However, the next day she learned that she had lost an important order from clients in America for future design work, and reluctantly decided that she could not afford the new computer system at the present time. She immediately contacted Avalon by fax and asked the company to take back the computer (still boxed and unused) and refund the money paid. The company refused. 1. Advise her clearly and fully as to her rights under European Community Law (if any) to obtain a refund of the money she has paid for the goods from Avalon. If she is unsuccessful in doing so, can she obtain redress from any other person or body Ibanez (2004) studied the legal procedures against member states for breaches of EC law and the different aspects of the European Commission enforcement procedure under EC Treaty Articles 226 and 228. Ibanez discusses the policy and strategy in enforcement proceedings and the European model that is followed for enforcing and supervising EC law. The Commission can sue Member States before the European Court of Justice or ECJ under Article 228 if a member state breaches the laws as required to be followed by the states. The enforcement of Commission decisions would be related to new developments and procedural aspects at the European level. The general procedures of the EC law show that the EC Treaty grants the Commission the power to "ensure that the provisions of this Treaty and the measures taken by the institutions pursuant thereto are applied." This relates to the EC Treaty Article 211 that grants a general power to the Commission and the EU can use the provisions of the EC Treat y for fighting Member State noncompliance. For an imaginary directive adopted by the Council in May 2005, if any one member state fails to keep up to the directive of EU law or the EC Treaty, according to the Articles 211, 226 and 228, the European Commission can take legal action against any member state that fails to comply to EC Treaty requirements or as expected from a member state. Article 226 is in fact based on a legal model of integration between

SABMiller Plc and Kingfisher Plc - Coursework Example Although regarded as a non-cyclical industry, beer brewing has been affected by reduced overall demand for goods worldwide, including consumer goods, and SABMiller saw its turnover drop, albeit not very significant, in 2009. According to the CBI Economic Forecast published in December 2009, there will be a modest recovery of world economic activity in 2010, but the longer-term trend will not resume until 2011. For the UK, this marginal growth will be driven by continuing strong Government spending, a modest increase in exports, and some recovery of consumer spending. The UK Gross Domestic Product is forecast to grow by 2.2 percent this year, and 2.5 percent the year after that. Consumer spending growth will be hampered by high energy costs, unwillingness to borrow, and the need to save for future needs. The company belongs to the non-cyclical consumer goods and services sector, and the beverages/brewers industry. (Reuters). According to Hoovers, industry demand is driven by consumer preferences for alcohol consumption as well as demographic trends. As is true for most consumer products, success often goes to large companies because of their effective sales operations, broad distribution networks, and economies of scale. The industry is capital intensive. The top competitors of SABMiller plc are, Diageo plc, Heineken NV., and Anheuser-Busch InBev. The latter replaced SABMiller as the worlds biggest brewer after InBev acquired Anheuser-Busch for $52 billion in 2008. The company recorded a revenue level of US$18.7 billion in 2009 and a net income of US$2.16 billion compared to US$2.29 the year before. Sales in 2009 dropped 12.6 percent due to the global recession, but overall revenue has grown by an annual average of 10.5 percent over 5 years and 6.9 percent over three years. Earnings per share average 18.6 percent over five years and 6.13 for the last three years.

Are Leaders Born or Made Essay Example | Topics and Well Written Essays - 2000 words
Are Leaders Born or Made - Essay Example 9 Case Study Rolls Royce is a technology leader which employees 36,000 people in offices, manufacturing and service facilities operating in 50 countries. The company has long history of employee development but currently they are reexamining their development strategy. In 2005 a review of talent management which was up till now being managed locally within business units was done and new concept of talent management at global scale was introduced (Jane Yarnall, 2008). Rolls Royce realized the importance of talent management and that it should not be a standalone approach. Leaders can only emerge by identifying the potential talent at the grass root level and then nurtured and developed according to the organizational needs. The efforts which were previously been done at the regional level needs to be coordinated and aligned with each other and with organizational objectives to maximize its effectiveness and broadening its horizon. After reviewing their current policy and assessing it s strengths and weaknesses they charted out a number of steps for their global talent management program. A new stream of graduates was hired as trainee managers or the leadership graduates, developing a pool for future leadership. And as this pool of candidate grew in experience and maturity, succession planning was successful. This program had a clear and predefined set of roles and expectations from the line managers, while at the same time, there was development of a human resource database, keeping in mind the global focus. Career development and progression plans were developed and communicated objectively to the employees, for assuring and ensuring no conflicts by being absolutely objective, alongside coaching and mentoring. This, in turn, assisted the business to focus on leadership development with a strategic eye for the future requirements10(Jane Yarnall, 2008). The above charted out plans further strengthens the view that Rolls Royce also believed in the theory that lead ers are more made than born as suggested by Daft and a no of other writers on the theory of leadership development. Rolls Royce realizes the importance of the quality of human capital and strongly believes that the success of the company depends on how the management programs for all the employees have been established within the company. Before launching this global talent management program Rolls Royce actually conducted a self analysis survey to identify the weaknesses of the old development program. In this self analysis program they asked themselves the following questions. Where do they stand today? How healthy is their existing succession plan? A survey about internal and global demographics What metrics should they use? What kind of leadership is required for the future? An analysis of the need of future graduates Identification of real indicators of high potential What additional development programs are required An analysis of competitors leadership development program If we take a closer look at these questions then it reveals that it was actually a journey for the company through the stages of leadership development as suggested by Daft. Once it was decided at Rolls Royce that born leaders are a rare commodity and cannot be found easily, Since there is no

Human Resource Information System Assignment Example | Topics and Well Written Essays - 750 words
Human Resource Information System - Assignment Example In this regard, P&G may consider using the self service portal which, acts as an access point to an organizationââ¬â¢s HRM information (Kavanagh, Thite and Johnson 296). This would involve the use of computers, and intranet via the internet from all its 80 branches. This approach would help P&G to achieve a specific competitive position through knowledge and skills applied on HR technology (Kavanagh, Thite and Johnson 291). P&G could also utilize a shared-service center. This would help the company to focus on value creation by offering excellent services to customers while ensuring cost reduction through increased efficiency and constant improvement (Kavanagh, Thite and Johnson 291). Additionally, human resource outsourcing could also be helpful in that, it can help the P&G 80 branches to contract with internal venders of the countries they are operating to perform HR services and activities. This can help P&G both financially and strategically. Question 2 Even with so many count ries and governmental organizations involved, P&G can still achieve sufficient standardization through HRIS to gain increased savings. However, this should involve a proper articulation and adherence to compliance regulations with government mandates (Kavanagh, Thite and Johnson 312). ... Question 3 Internal customers would view the move from decentralized to centralized shared services as a good move because this will enable the provision of excellent services with greater efficiency, value generation and improved services. Additionally, moving from decentralized to centralized shared services makes customers managers in business units such as operations and marketing. Besides, such measures allow internal customers to assess the value of consolidated unit to facilitate continuous improvement by shared services centers managers (Kavanagh, Thite and Johnson 300). Question 4 Changes experienced as a result of moving from decentralized to centralized shared services can be measured from internal customer perspective. One of the ways to measure these changes involves reduction in the overall financial cost in relation to HR administrative processes (Kavanagh, Thite and Johnson 300). Since centralization of shared services aims at improvement of quality and customer satis faction, such improvements can be assessed in terms of changes experienced in this towards this effect. Additionally, since centralized shared services ensures cost reduction in employees improved performance, therefore, employeeââ¬â¢s retention and training costs can be another method to measure of the changes (Kavanagh, Thite and Johnson 301). It is also apparent that employeeââ¬â¢s royalty is also ensured through productivity and morale. Therefore, this can also be one of the ways to measure the change realized as a result of moving from decentralized to centralized shared services. Question 5 P&G can utilise various measures for the administrative

Movie Critique Essay Example | Topics and Well Written Essays - 2000 words
Movie Critique - Essay Example Through the relationship between these two men, the viewer is able to see many psychological factors at work which help to make this work environment so unbearable. It is also possible to see that Bill Lumberghââ¬â¢s style of leadership is responsible for the majority of these problems and, therefore, he should be blamed for the eventual destruction of the company. A force that allows for employers to have a psychological advantage over their employees is job security. There have been massive layoffs lately and those who were lucky enough to keep their jobs must work hard to ensure that they are just as lucky when the next cuts are made. This gives the employers all of the power, as they can work the employees harder, without any backlash because there are so few jobs in many sectors. The employers know that if an employee does not perform up to expectations, then someone else will be readily available to take his or her place. The employees also know this so they must work hard to keep their jobs. In Office Space, Lumbergh utilizes this as a method of employee motivation, as many of the characters are terrified of losing their jobs. He also uses this threat to get certain members of the company to work on weekends, as they must do so in order to keep their jobs. This movie shows a negative form of employee motivation, as employees do not resp ond will to threats like this, as can be seen in this film. A manner of employee motivation that would work better would be incentives for working overtime and working harder than everyone else. If Lumbergh would offer employees like Peter bonuses for doing extra work, he would be able to get more out of them on a regular basis and would keep them more motivated. Happy workers are much easier to deal with and Lumbergh does not do an adequate job of keeping his employees happy. Longer hours and averted overtime pay would completely ruin employee moral and

Global Corporate Strategy Essay Example | Topics and Well Written Essays - 500 words
Global Corporate Strategy - Essay Example In an example, two airline companies might create a strategic alliance through bringing up their resources together to create a strong advertising website in order to develop a more effective marketing process. Strategic alliance is more effective in companies that have closely related products (Vedder, 2008). One of the major differences between strategic alliance and other joint ventures is that the business that forms an alliance remains independent. Alliances involve transfer of technologies, economic specialization and sharing of different expenses and risks. Types of strategic alliances include; Joint ventures, equity strategic alliances and global strategic alliances (Kleymann & Seristà ¶, 2010). Unlike strategic alliances where businesses involved in alliances remain independent, merging involves dissolution of both businessesââ¬â¢ activities to form a single entity.

Global Consumer Preferences The Gap success is provide merchandise that suite to customers fashion taste. The time consume to reach every purchases is slow, so I cannot respond to new or changing fashion trends or consumers acceptance of my products. Our global specialty retail business fluctuates according to changes in consumer preferences ,dictated in part by fashion and season. Due to the time consume to reach my customers, our fashion trends will be slower and customers will go to my competitors and this situation will affect my company sales. The out dated fashion have to mark down and sold. For example The Gap INC United States Selling the 2012 spring fashion but in Singapore, there are still selling winter fashion. Globalised Production My products are manufactured by independent third parties. As result of out sourcing, my product are directly affected by the increases of cost. For example the cotton price increase will directly affect my company gross profit. If the current manufacturer charges my company with high price, I will get a new manufacturer. When I go for new manufacturer, there will be delays in production and added costs as a result of giving training to new vendors in making my products, quality control standards, and environmental, labour, health, and safety standards. The delay on production will affect the sales and net income of company. Due to globalised production, the finish goods need to transport from manufacturer to retailer of different nations. There are possible of delay in the shipment and delivery time. The factors that causes delay are availability of transport, work stoppages, port strikes, infrastructure congestion. If the goods are requested goods, I need to arrange for faster tran sport such as by air. The time of transporting goods from air is faster but the cost of transport are high. Technological Innovations Apparel and fashion industry has experience a rapid change in technological changes over the years.

Changing social and medical attitudes affect ill health
Changing social and medical attitudes affect ill health Health was defined by The World Health Organisation in 1948 as, a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Varying definitions of health can be found depending on an individuals perspective. Medics will focus on biological cause while sociologists argue that health is a product of social and environmental factors. (Naidoo Wills, 2009a: chapters 12) In the early 19th Century there was focus on the elimination of diseases such as plague, smallpox and cholera. With industrialization and rapid urbanization, as the 19th century progressed, health issues became focused on environmental issues such as clean water supplies, disposal of waste and better housing. (Naidoo Wills, 2009b:p3) Health inequalities have been recognised in the UK since William Farr first published statistics in 1837. It remains the case today that health is directly influenced by social class and the effects of poverty and associated behaviour factors. (Ewles, 2005: pp243-245) Urbanisation is the process of population concentration. The 19th century saw the massive growth of cities and the migration of the population from the country and into cities on a scale never seen before. Houses became over crowded with entire families living in one room. The process caused huge problems for public health. (Pathfinder pack on Urbanisation the move to the city in the 19th century, n.d.) (Urbanisation in the nineteenth and twentieth centuries, n.d.) Urbanisation was the most profound effect of the Industrial Revolution which developed at a pace in Britain between 1800 and 1850. Cities grew rapidly and lacked sanitation, accumulated sewage, had high rates of crime and poverty and consequently high rates of disease. Heavy use of coal led to an accumulation of dirt and grime. (Urbanisation, n.d.) Larger cities were a necessity of industrial growth but the conditions they brought were in many ways regressive. (Lee, 1995:p48) The Growth of Cities 1801-1901 in thousands. City 1801 1851 1901 Birmingham 71 233 523 Bradford 13 105 280 Leeds 53 172 429 Liverpool 82 376 704 Manchester 70 303 645 Newcastle 33 88 247 Nottingham 29 57 240 Sheffield 46 135 407 (Reynoldson 1996:p10) A part of London was described by Thomas Southwood-Smith in 1838 as follows, Beckwith Row has an open drain. The houses have common, open privies (toilets) which are in the most offensive condition. In one house I found six persons living in a very small room, two in bed, ill with fever. (Reynoldson, 1996: p110) http://t2.gstatic.com/images?q=tbn:HcwSJOrT5lACaM:http://www.makingthemodernworld.org.uk/stories/the_industrial_town/06.ST.02/img/IM.1064_zp.jpg Slums in 1872 London [Making the modern world, n.d.) There were no controls on the standard of housing and the Government maintained a laissez-faire attitude. That is they believed there should be no central government intervention. Local efforts were haphazard and insufficient. (Todd, 2002:p31) Smallpox was the greatest killer at the beginning of the 19th century. Jenner observed that milkmaids who caught a mild form of the disease or cowpox didnt develop smallpox. From this study, Jenner discovered a method of vaccination against smallpox. He faced much opposition to his discovery as some people simply didnt like anything new while others described his theory as bizarre. Jenner wasnt a fashionable London Doctor and he couldnt explain how or why vaccination worked so he wasnt taken seriously. Some people called it an interference with nature. (Lee 1995:p44) (Todd, 2002:p32) Success of the vaccine was put down to coincidence by some Doctors who made money through an older practice of inoculation. (Lee, 1995:p44) A smallpox epidemic, during which 40,000 people died, resulted in the government making the smallpox vaccination compulsory in 1840 even though some continued to argue that this measure was against human rights. Smallpox declined, until by 1900 it had almost disappeared. This was the first example of the government accepting responsibility for an area of public health. (Lee, 1995:p44) Cartwright in A social History of Medicine (1977) describes Jenners discovery as one of the most beneficial changes in the history of social medicine.his work is recognised as the starting point of attempts to combat infection by immunization. (adapted from Lee, 1995:p45) Jenners work and the train of events that followed affected a social revolution. Individual choice was sacrificed for the interests of the community. (Cartwright, 1977:p92) At the same time, two other diseases also presented a challenge. TB cholera were more difficult to tackle as both diseases spread as a result of poor living conditions. TB or consumption took hold as towns grew and took over from smallpox as the greatest killer disease. Cholera epidemics struck several times during the first half of the 19th century. In 1854 John Snow proved that cholera was connected with polluted water. He was able to show that a water pump in the Broadgate area of London was the origin of 500 cases. People using another pump nearby did not catch the disease. Once the Broadgate pump was put out of action, no further cases were reported in the area. (Lee, 1995:p51) http://t3.gstatic.com/images?q=tbn:dkmPPVrjlaE3NM:http://historyday.coldray.com/wp-content/uploads/2008/12/john-snow.jpg John Snow (1813-1858) http://t2.gstatic.com/images?q=tbn:fd12xpKjN8GveM:http://thedoublethink.com/wp-content/uploads/2009/04/450px-john_snow_memorial_and_pub.jpg Replica Broadgate pump (www.health.eku.edu/ehs/faculty/darryl_barnett.htm) A fierce debate raged about responsibility for public health with strong views about the role of the government. Several arguments for non-intervention were put forward including that government intervention would interfere with peoples basic rights or the freedom to be dirty. Some people believed that if the state acted to improve housing the moral courage of the poor would be reduced. (Lee 1953: p53) A letter to The Times in 1854 read, We prefer to take our chance with cholera than be bullied into health. Many people have died from a good washing. (Quoted in Lee, 1995:p53) But several important people put the case for action by the state including William Farr and Thomas Southwood-Smith who both recommended government intervention. Tonge in Challenging History 1700-1914 says, Of all the campaigners for improved public health, Edwin Chadwick stands monumentally above the rest. Chadwick stressed the connection between public health and disease and how such factors needed to be addressed by government intervention. Chadwicks report The sanitary conditions of the Labouring Population of Great Britain was published in 1842 and recommended that the government take steps to improve drainage, remove rubbish from the streets and improve the water supply. (Wilkes: 2007: p 92) (Reynoldson: 1996, p 113) http://t0.gstatic.com/images?q=tbn:iK4kyWJkVFmbWM:http://wpcontent.answers.com/wikipedia/commons/thumb/9/9e/SirEdwinChadwick.jpg/200px-SirEdwinChadwick.jpg Edwin Chadwick (www.answers.com/topic/edwin-chadwick) The government distanced itself from Chadwicks report largely because of the influential figures he has discredited and the laissez-faire debate lasted for much of the 19th century. Loosely translated this means do not interfere. Some members of parliament were making money from rent on the slums and refused to tear them down. Eventually, however, the social effects of economic growth were so severe that gradually the state became more involved in issues of public health. The great stink in 1858 (when a heat wave caused the Thames to smell worse than ever) inspired the government into action. (Wilkes 2007). In 1861, Prince Alberts death from typhoid was attributed to contaminated water from the Thames and put further pressure on the government to do something. (Cartwright, 1977, p95) In 1867, working class men were given the right to vote. Political parties realised that by promising to improve living conditions, they could secure the working class vote. When the Conservatives won the 1874 election, they introduced many public health reforms. Aaron Wilkes (Medicine through Time) sees this as the most important reason why politicians began to make improvements. Some cities including Birmingham and Liverpool started some clearance of slums, built sewers, improved refuse collection services and opened public baths. Some private companies such as Lever, Cadbury and Rowntree saw the benefits of providing good housing for their workers. It was, however, not until after the First World War that extensive slum clearance was commenced. (Lee 1995:p57) Miasma or the infectious mist given off by rotting animals, rubbish and human waste was thought to be the cause of many of the epidemics in the 19th Century. Scientists identified germs using a microscope but believed that the disease caused germs rather than the other way round. This was known as spontaneous generation. Louis Pasteur questioned this theory and was able to prove that germs caused disease but many Doctors wouldnt entertain his ideas. It took the German Doctor, Koch, to apply Pasteurs theory to human disease. Koch was able to prove that germs caused TB, cholera and anthrax. (Mantin Pulley, 1988:p49) http://t2.gstatic.com/images?q=tbn:OdyqTCWJiq49tM:http://web.ukonline.co.uk/b.gardner/pasteur.jpg Louis Pasteur (web.ukonline.co.uk/b.gardner/pasteur.htm) Pasteur built on Kochs work and developed a vaccine for rabies. Soon the germs responsible for typhus, tetanus, typhoid, pneumonia, meningitis, plague, septicaemia and dysentery were identified. Once germs were discovered vaccines could be made. Scientists now had a powerful new weapon to fight disease. (Wilkes, 2007:p88) Vaccination is one of the greatest success stories of modern medicine. Smallpox has been wiped out and tuberculosis and polio have been significantly reduced. Children are now regularly vaccinated against a number if diseases. (Lee, 1995:82) The smallpox vaccine was given free in 1840 but it was another 100 years before vaccination against TB was provided. This was followed by vaccines for diphtheria, whooping cough and tetanus (1954), polio (1955), measles (1964) and rubella (1969). (Lee, 1995:p82) Progress continues today as a new vaccine has been introduced this year which protects girls against the virus that causes cervical cancer. The 19th Century also saw developments in surgery. The problems were pain and infection. The breakthrough came with the development of anaesthetics and antiseptics. (Lee, 1995: pp5961) William Moston experimented with ether and James Simpson tried chloroform. As with most medical discoveries, the first reaction of surgeons was criticism. Some argued that the long term effects were unknown and others objected on religious grounds. In some cases patients still died if the anaesthetic wasnt correctly administered. Some people thought that surgeons would cut off whatever they liked while the patient was unconscious and army Doctors thought the use of anaesthetic was soft. (Reynoldson, 1996:97). Others said that it was unnatural to ease a womans pain during childbirth. The breakthrough came when Queen Victoria used chloroform during the birth of her eighth baby and use of anaesthetics then became common practice. (Wikes, 1988: p101) The use of anaesthetics was a great step forward but it didnt stop deaths from infection after the operation. In the 19th Century hospitals were dirty places. Patients with disease were herded together, the same instruments were used on many patients and Doctors didnt change their blood stained coats between operations. Doctor Joseph Lister was influenced by Pasteur and believed it important to kill the bacteria in the operating theatre. He did this by spraying carbolic acid (although his theory wasnt quite accurate as the bacteria was really on the instruments not in the air, but the incidence of infection was reduced by some of the antiseptic also landing on the instruments in use). Lister encountered much opposition as nurses and doctors complained about the smell and the amount of time taken to clean the theatre. Lister didnt communicate well and surgeons who didnt work with him were not convinced. (Lee.1995: p64) Eventually antiseptics and cleanliness came together to form the modern approach to surgery or asepsis. By the beginning of the 20th century Doctors were operating in a germ free environment, using sterilised equipment and wearing gowns masks. Death rates reduced massively; at Newcastle Infirmary before 1873, 59.2% of patients died after an operation (pre antisepsis), after 1873 only 4% died (post antisepsis). (Figures from The Lancet in 1878 in Lee, 1995:p65). Use of a carbolic spray during an operation circa. 1880 and the sterile environment of a modern operating department. http://t0.gstatic.com/images?q=tbn:476AON2yuy0EGM:http://www.answersingenesis.org/assets/images/articles/aid/v4/antiseptic-surgery.jpg http://t0.gstatic.com/images?q=tbn:sgiACWjAMvVpNM:http://www.workingmats.com/images/Operating_Theatre_115313_08.jpg (www.history.langtreeshout.org/tag/lister/) (www.workingmats.com/images/Operating_Theatre) During the Crimean war (1854/56) Florence Nightingales influence saw death rates reduce as she was responsible for organising better water supplies and food and keeping the wards clean. Fiona Reynoldson in Medicine Through Time says the death rate of wounded soldiers in hospital reduced by 40% under Nightingales influence. In 1899 a recruitment campaign for men to fight in the Boar War highlighted the fact that around 40% of those volunteering were unfit for military duty. In 1904 a government report concluded that there needed to be more government intervention to improve the health of children. When the Liberal government was elected in 1905, a large number of reforms were introduced including free school meals for poor children, a free school medical service and women were taught about hygiene and childcare. Pensions for over 70s and basic sick and unemployment pay were also introduced. Over the next 30 years successive governments took measures to improve the health of children and mortality rates dropped. (Wilkes, 2007:p114) During the 1st World War, Prime Minister Lloyd George promised soldiers returning homes fit for heroes. The government set itself a target of building half a million decent homes by 1933. The war revolutionized society and made us move in a new and different direction. (Fenwick-Baines, 2009) When Britain was plunged into the First World War the need for a way to combat staphylococcus, a highly resistant bacteria, was urgently needed. Many soldiers died, not from the bullets, but from the infection caused by the bullets deep in the body. Conditions in the trenches were appalling and wounds quickly turned septic. Alexander Fleming worked on wounds and infections during the war and made an important discovery that the penicillin mould would attack and kill certain bacteria. Fleming is credited with its discovery but other scientists went on to develop the drug for human use. Initially, money wasnt available for its manufacture but The Second World War was vital in progressing its mass production. The American government recognised its value and agreed to pay drug companies to manufacture vast quantities to treat injured soldiers. Penicillin is still the most widely used antibiotic and is used to treat many bacterial infections, many other antibiotics followed . By the end o f the war, drug companies made it available for general use. (Wilkes, 2007: p118) (Board works, 2003) The problem of blood shortage baffled Doctors for centuries but hundreds of wounded soldiers provided the strongest possible reason for expediting the establishment of the new blood transfusion service. This is another typical example of war acting as a catalyst for change. The 2nd World War actually saw the health of the nation improve as rationing meant that fatty sugary foods were in short supply. The government urged people to dig for victory and grow their own vegetables. The government promoted healthy living including basic hygiene and immunisation against diphtheria all part of a campaign to have a healthy nation able to stand up to Hitler.(Board works, 2003) Dig For Victory http://www.5aday.nhs.uk/images/top_tips_2/pic_carrot_eyes.jpg The Dig for Victory campaign during the 2nd World War is remarkably similar to todays Try 5 message. (www.bbc.co.uk/dna/h2g :2009) (www.5aday.nhs.uk: ) Birth rates reduced with the availability of contraception and with fewer mouths to feed, better food was provided for children. Between the wars little changed as the economy experienced difficulties (the 1930s depression) but during and after the Second World War there was a further huge development. In 1942 The Beveridge Report recommended a welfare state and that the government should help people from the cradle to the grave. After the war people wanted change and a social revolution. The war was over and it was time to look to the future. Some people did not like the new ideas and said everyone should be independent, the rich objected to paying heavier taxes to fund the welfare state. (Cartwright 1977: p173) The suggestions made by Beveridge were not immediately put into force as the cost was questioned but when Labour took power in 1945, the NHS was born. From the introduction of the NHS in 1948, everyone was entitled to free medical treatment. The welfare state and the NHS in particular met with opposition. Churchill and the conservative party felt the cost was too much for the economy to bear. Critics suggested the health service was wasteful and that people were getting things they didnt need. The service was also free to overseas visitors and some argued that this was over-generous. The BMA objected, initially fearing Doctors would lose their independence and that their income would reduce as an employee of the NHS. Compromise was only reached when agreement was given that Doctors would still be able to take on private, fee-paying patients. (Lee 1995:95) (Reynoldson, 1996:118) (Lloyd T. 1986:289) (Wilkes, 2007:123) The dawn of the NHS was a huge change in the way people accessed healthcare. After the war New Towns were built to replace the inner city slums. The 1947 Town and Country Planning Act identified green belts where houses would not be allowed to swallow up the countryside. In 1954 the clean air act reduced smoke and smog in cities. In 1980, The Black Report stated that although health had improved since the introduction of the welfare state, huge inequalities in still existed between the rich and the poor. It concluded the reason for the disparity to be poverty. (BBC History, 2009) 1992 saw the publication of The Health of the Nation. This was the first ever strategy for healthcare improvement setting out objectives and measurable targets in four key areas: heart disease stroke, cancers, mental health, HIV/AIDS and accidents. The areas were selected because they were either a major cause of premature death or avoidable, interventions were possible and achievements could be monitored. (Childs, 1996) In 2000 health authorities became more autonomous and the establishment of a healthy competition between them. However, postcode can now determine the quality of healthcare provided and whether the hospital can afford or is willing to pay for the specific drugs and treatments, Press reports in recent months have highlighted how some patients been declined expensive cancer drugs by a particular hospital while it is provided to patients of a neighbouring authority. This contradicts the ethos of the NHS its position of equality of provision for all. Massive changes took place throughout the 19th and 20th centuries in terms of public health provision and scientific and medical discoveries. The NHS didnt stay completely free. It is rarely out of the news as waiting lists get longer because people are living longer. The main problem is funding as modern drugs and treatments are expensive.Most Infections and diseases can be prevented or cured but Doctors still struggle with heart disease and cancer. Viral infections like the common cold and AIDS cannot be cured and emphasis is now placed on educating people about how to avoid diseases like AIDS and lung cancer through lifestyle changes. (Wilkes A. 2007:p124) Two aspects of modern living which can have a detrimental effect on the health of the population are; smoking and diet. Although initially promoted as cleansing the lungs by tobacco manufacturers, the detrimental effects of smoking have been know for half a century. Naidoo Willis in Public Health and Health Promotion: developing practice highlight smoking as the single most preventable cause of ill health and premature death. A third of cancer deaths are linked to smoking and it is also linked to heart and lung disease. Smoking is estimated to cost the NHS à £1.7billion each year (Dept of Health 1998 Royal College of Physicians 1992 in Naidoo Willis 2009) Marlboros for Mummy Examples of early cigarette advertising. http://news.bbc.co.uk/nol/shared/spl/hi/pop_ups/03/uk_goodbye_tobacco_ads/img/2.jpg (news.bbc.co.uk//html/2.stm) (news.bbc.co.uk//html/2.stm, 2009) Early Cigarette advertising actually promoted the health benefits claiming relief from asthma, wheezing and hay fever. Craven called itself the Doctors Choice. Marlbroro promoted the benefits of smoking to Mothers. In 1998 the government banned tobacco advertising and targeted an anti-smoking campaign at children, pregnant women and disadvantaged adults. Demand is controlled by taxation and a ban on smoking in a public places including pubs. Obesity is a growing problem and has trebled since 1980. It is linked to social disadvantage and the way childrens lifestyles have changed over the last 50 years (more TV/computer time, less physical activity, convenience foods, working Mothers with less time). There is mounting pressure to ban the advertising of junk food. A high fat diet has been linked to heart disease and some cancers. NHS spending on sickness attributed to obesity has been estimated to exceed à £3.6billion. (Joint Health Surveys Unit, 2002 Mulvihill Quigley, 2003 Naidoo Willis 2009:p239). Last year the government launched the change4life education campaign to promote the message eat well, move more, live longer which encourages parents to make sure their children have a minimum of one hour exercise each day and reduce the amount of fat in their diet. http://t2.gstatic.com/images?q=tbn:lg0Gy-_B7JmSnM:http://www.sunseaandcycling.com/Files/Images/C4L_master-logo-rgb.jpg http://t1.gstatic.com/images?q=tbn:n39JMfcD3UH9DM:http://images.teamsugar.com/files/upl2/1/15111/11_2009/cb3240a4f35793dc_uk-change-4-life-ad.jpg (www.nhs.uk/Change4life, 2009) Public Health interventions have evolved as the government have taken responsibility for living conditions and health service provision, mass vaccination and immunization programmes. The epidemiological transition in the 20th Century saw the main causes of death and illness shift from infections to illness such as heart disease and cancer where lifestyle is a huge factor. (Naidoo Wills 2005:4) Current public health measures include mass screening programmes for example for breast and cervical cancers, extensive vaccination programmes as well as education and advice delivered by practitioners and the media campaigns. Examples of recent/current health media campaigns. http://t1.gstatic.com/images?q=tbn:vS8pq7HettyShM:http://www2.glos.ac.uk/offload/staff/news/swineflu.jpg http://t3.gstatic.com/images?q=tbn:qNfrnzs-ahQTYM:http://draust.files.wordpress.com/2009/01/nhs-measles-poster.jpg http://t0.gstatic.com/images?q=tbn:gslEVyv3VyG7SM:http://www.elements4health.com/images/stories/conditions/breast-cancer-ribbon-2.jpg (www.chesterfield.gov.uk/lowgraphic)..

Verification Of Faradays First Law Of Electrolysis
Verification Of Faradays First Law Of Electrolysis My research question How can Beers law be used to verify Faradays First law of electrolysis and to determine Avogadros number and Faradays constant by electrolysis of 1.000 mol dm-3 copper sulfate (CuSO4) solution using graphite electrodes? is an indirect question to the investigation. I was always interested in verifying laws and learning about interdependence between laws. I was so keen in finding how that how the nature of one law depends upon another law as chemistry a whole subject depends upon multiple concepts. So I took this opportunity to show how one law can be proved using another law. Here in my research I have shown how Beers law can be used to verify Faradays First law of electrolysis and I have also used Beers law to determine Avogadros number. This research clearly indicates that there is interdependency between laws. In the verification of Faradays First law of electrolysis of CuSO4, we generally focus on mass of Cu deposited, but not much on color. My focus was that how to use this phenomenon / property of change in intensity to calculate mass indirectly. The same concept of absorbance in Beers law applies while determining Avogadros number. I did the experiments to verify Faradays First law of electrolysis and to determine Avogadros number in indirect manner. Indirect methods have often helped scientists to get their results better and we also have good examples for Back titration and chromatography. So with the same expectation in mind, I came with such a topic for my research. Slight modification in the experiments can really help. I did use graphite electrodes because they are cheap, it is therefore widely used in electrolysis rather than platinum as it is costly. The disadvantage for graphite electrodes is, it flakes off and therefore mass readings of Cu deposited over graphite electrode are highly unreliable. So as the result is highly unreliable, we might not get the accurate readings of the mass of Cu deposited at cathode. But if we use the colorimeter technique to find out the deposition, the mass of graphite lose in the electrolysis process is not affected. I mainly focused upon the absorbance value by the diff erence of color. Once while performing an experiment on electrolysis during my school days, I was using graphite electrodes and I noticed that graphite particles were flaking off the electrodes in electrolyte solution during the experiment. The amounts of carbon particles lost from graphite were very less and so was neglected but later I thought that it might be affecting the result in some or the other way as in the experiment we were supposed to weigh the electrodes to find out the amount of Copper deposited on the cathode. I used to think that if graphite electrodes are themselves losing some mass, then how the electrode can give accurate readings or a reliable result. The copper deposit over cathode is not strongly attached to the cathode thus there are chances that copper deposited on cathode may be lost by mishandling of the electrode before taking direct mass reading; this made me think about an alternative method which would be more accurate as well as reliable, where in the electrodes will n ot have to be removed from the experimental set-up at all! 2. THEORY I would like to start by mention something about electromagnetic spectrum as my experiment deals with Beers law which can be obtained through absorbance value. Absorbance in the colorimeter is found by setting a particular wavelength and there is different wavelength for different objects, similarly there is a particular wavelength absorbed by CuSO4. Electromagnetic radiations have frequencies and all the possible frequencies are covered in the range known as electromagnetic spectrum. The property of characteristic distribution of electromagnetic radiation emitted or absorbed by any specific object is the electromagnetic spectrum of that object. Electromagnetic spectrum has its range from low frequencies which are used for modern radio to the high frequency like gamma radiation. It covers wavelength from thousand kilometers to small fraction. The limit for the long wavelength is the universe itself and shortest wavelength is near to the Plank length even if the principal states the s pectrum is infinite and continuous which is truly acceptable. In the Vernier colorimeter we have option to select the wavelength from range 430nm, 470nm, 565nm and 635nm. According to the user guide for Vernier colorimeter CuSO4 will yield a good Beers law curve at 635nm. Therefore it says that the wavelength absorbed by CuSO4 lies in the range 635nm and I had used 635nm range throughout the experiment for finding the absorbance of CuSO4. In the study of light we have the Beer-Lambert law which is also known as Beers law and the law is related to the absorption of light to the properties of the material from which the light passes. Electrolysis is a process to separate bonded elements and compounds .The methodology followed is by passing an electric current through bonded elements and compounds. Electric current is passed through a conductor called as electrode. Electrodes are found in various forms like wires, plates, and rods. Electrodes are mainly constructed of metal, such as copper, silver, lead, or zinc. Electrodes can also be made up of nonmetal substance, such as carbon. There are commonly used Graphite electrodes which are made up of carbon. In my experiments as I have used graphite electrodes, I am indirectly using nonmetal substance having carbon. Inert electrodes do not take part in the chemical reactions for Examples, Graphite and Platinum electrodes. Active electrodes take part in chemical reactions where the anode itself produces metal ions which get discharged at the cathode for Example, Copper electrodes. I noticed that graphite rod was losing carbon particles on stirring, thats the reason why direct method to find mass of copper deposited was not adopted by me. The electrodes which I used for the experiments were Inert electrodes and I used graphite electrodes because platinum electrodes were not available and they were costly. An electrode passes current between a metallic part and a nonmetallic part of an electrical circuit. Most frequently, conductors that are metallic carry electrical current. In other circuits, however, current is passed through a nonmetallic conductor. In an electrochemical cell, an electrode is called either an anode or a cathode. An anode is an electrode at which current leaves the cell and oxidation takes place. For example, an anode is the positive electrode in a storage battery. Faradays 1st Law of Electrolysis states that, The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode. Quantity of electricity refers to the quantity of electrical charge, typically measured in coulomb. Throughout the investigation I had rounded off few of the readings to get correct significant figures. Using a colorimeter: This method is only useful if one of the reactants or products is coloured. It is a more satisfactory method than titration for two reasons: firstly, no sampling is needed, and secondly, a reading can be taken almost instantaneously. So quite rapid reactions can be followed, especially if the colorimeter is interfaced to a data logger or computer which can plot a graph of concentration versus time as the reaction proceeds. A colorimeter consists of a light source with filters to select a suitable colour (i.e. set of wavelengths) of light which is absorbed by the sample. The light passes through the sample onto a detector whose output goes to a meter or a recording device. The colorimeter usually needs to be calibrated and even I calibrated the Vernier colorimeter with distilled water before conducting the experiments. Calibration is done to establish the relationship between its readings and the concentration of the copper sulfate used. 3. INVESTIGATION My investigation was divided into three main sections, starting with verification of Faradays First law of electrolysis, secondly to determine Avogadros number and finally in determining Faradays constant. I had predicted that the results of investigating Faradays First law by direct method and indirect method will give almost the same result and I was successful in getting that. But according to my assumptions, more accurate readings can be obtained by the indirect method of colorimeter using Beers law technique. It is also useful to determine Avogadros number and Faradays Constant as the result which I got through the Beers law technique was almost near to the true value of Avogadros number and Faradays constant. 3.1 APPARATUS AND MATERIALS Beakers (250 cm3 ÃÆ'- 1) Volumetric flask (100 cm3 ÃÆ'- 5 and 1000 cm3 ÃÆ'- 1) Measuring Cylinder (100 cm3 ÃÆ'- 1) Digital Weighing Balance Graphite electrodes Copper sulfate (CuSO4) Ammeter (0-500mA) Rheostat (0-500 à ¢Ã¢â¬Å¾Ã ¦) DC variable voltage source (0 12 V) Vernier labquest colorimeter Cuvette 3.2 CIRCUIT DIAGRAM OF EXPERIMENTAL SET UP The above shown diagram represents the electric circuit diagram of the entire experimental setup. A DC variable voltage source (0-12 V) was used as a battery. Rheostat was use to control the current coming from the battery because I was recording the Ammeter readings and I wanted the readings on the Ammeter to be constant throughout the experiment. I used Rheostat because the Ammeter reading was fluctuating and not remaining constant. The positive terminal of the battery was connected to the one end of Rheostat and the negative terminal of the battery was connected to the cathode. The connections were made in series as it was suppose to be for this experiment. The experimental set up was not disturbed during the electrolysis. During the investigation, there goes a chemical reaction within the experimental setup for the electrolysis of copper sulfate. Below are shown the reactions using graphite anode inert electrode. At cathode: Cu2+ + 2e- à ¢Ã¢â¬ ââ¬â¢ Cu At anode: OH1- 1e- à ¢Ã¢â¬ ââ¬â¢ OH x 2 [2OH à ¢Ã¢â¬ ââ¬â¢ H2O + [O] ] 4OH à ¢Ã¢â¬ ââ¬â¢ 2H2O + O2 Product at anode: Oxygen gas 3.3 PREPARATION OF SOLUTION Preparation of 1 dm-3 of reagents: The salt which I used in preparation of solutions was Copper sulfate pentahydrate, we commonly call it as copper sulfate. The molar mass of CuSO4.5H2O is 249.68 gmol-1. Therefore, to prepare a 1.000 molar of CuSO4 solution, I took 124.84 g of CuSO4 weighing upon a digital balance and then I diluted 124.84 g of CuSO4 in 500cm3 of distilled water. I had used distilled water to dilute the chemicals and to clean the apparatus rather using tap water because distilled water is more pure and using tap water can affect the result as it can indirectly react with the chemicals used for the experiments. It was very difficult to dissolve CuSO4 by using glass rod. Therefore, I had used magnetic stirrer to dissolve the crystals of Copper sulfate in distilled water. It was very time consuming in dissolving CuSO4 in distilled water but within few minutes the 500cm3 solution of 1.000 molar of CuSO4 was ready. From that 500cm3 of 1.000 molar of CuSO4, I prepared different 100cm3 solutions of concentration 0.8 molar, 0.6 molar, 0.4 molar and 0.2 molar. The volumes of Copper sulfate and Water in the different molar solutions are given in the below table: Concentration (Ãâà ±0.001 mol dm-3) Volume of CuSO4 (Ãâà ± 0.05 cm3) Volume of H2O (Ãâà ± 0.05 cm3) 1.0 mol dm-3 100 cm3 00 cm3 0.8 mol dm-3 80 cm3 20 cm3 0.6 mol dm-3 60 cm3 40 cm3 0.4 mol dm-3 40 cm3 60 cm3 0.2 mol dm-3 20 cm3 80 cm3 3.4 VERIFICATION OF BEERS LAW Beer in 1852 studied the effect of absorption of light on the concentration of solutions and found a similar relationship. Beers law states that when a parallel beam of monochromatic light enters an absorbing medium, the rate of decrease of intensity of the light with concentration is directly proportional to the intensity of radiation. Alternative statements can be expressed thus: When a parallel beam of monochromatic light passes through an absorbing medium, the intensity of transmitted radiation decreases exponentially as the concentration of the absorbing species increases arithmetically. Successive layers of equal concentration and thickness absorb equal fraction of incidental radiation. The readings for my Beers law experiments are as follows: Concentration (Ãâà ±0.001mol dm-3) Transmittance (%T) Absorbance (Ãâà ±0.001) 0.0 100.04 0.000 0.2 25.92 0.586 0.4 8.17 1.088 0.6 3.02 1.520 0.8 1.33 1.875 1.0 0.97 2.015 The graph which was obtained for Beers law: The graph was taken from vernier colorimeter using logger pro software to get the accurate readings for the absorbance of CuSO4. Here I observed a curve in graph and I felt that this abnormal for Beers law but later when I searched the reason for this, I got satisfactory answer as I was not gone wrong. Beers law is true for dilute solutions and therefore it is sure to obtain a straight line graph for dilute solutions. In the cases of highly concentrated solutions we get a curve which flatters if extended further due to the high concentration. This is the same case with my Beers law graph because the solution of CuSO4 was much concentrated. Deviations from Beer Lamberts Law: According to Beer-Lamberts law, absorbance A is directly proportional to concentration c. Thus, a graph of Absorbance v/s concentration should give a straight line passing through the origin. Often we find that the graph is not linear, and deviations occur. If the straight line curves upwards or downwards it indicates positive or negative deviations respectively from Beer Lamberts law. Deviations from Beer-Lamberts law a : no deviation; law is valid b : positive deviation c : negative deviation I got negative deviation for my Beers law graph. Negative deviation is shown in the above graph with option c. The Negative deviation in the graph was expected as the CuSO4 solution was highly concentrated. Deviations fromBeer-Lamberts law can be of three types: Real deviations: which are fundamental in nature. Instrumental deviations: which arise as a consequence of the manner in which the absorbance measurement is made. Chemical deviations: which arise as a result of chemical changes associated with concentration changes. The deviation which I got in my Beers law graph was Real Deviations and such deviation occurs due to Effect of concentration. The Beer-Lamberts law is valid for dilute solutions only. If the concentration of the solution is more than 0.01 M, Beer-Lamberts law does not strictly hold well, and deviations occur. At higher concentration, the molecules of the absorbing species come closer to one another, and due to this, charge distribution of neighboring molecules is affected. This results in an alteration in the ability of the species to absorb a particular wavelength of radiation. The extent of interaction depends on the concentration of the solution and therefore deviations are observed in concentrated solutions. The molar absorptivity à à · depends on the refractive index of the solution. If the solution is too concentrated it refractive index changes and thus à à · changes. This causes deviations from Beer-Lamberts law. This effect is negligible in concentrations

Arguments Against Distance Learning :: Teaching Education
There have been many critics that strongly advocate against the use of distance learning in elementary schools. With the increased availability and choice of new technology, comes many new concerns about the quality of instruction and the threat it may pose to the already established methods of teaching. Many believe that this new teaching method may replace the existing classroom all together, and wonââ¬â¢t give students the adequate face-to-face contact they need. Most critics fear that ââ¬Å"ineffective face-to-face teaching methods could be made even worse when they become technology basedâ⬠(Truell, 2001, p46). The computer and internet have become dominant distance learning technologies, and hold the potential to take away from the human aspect of learning, so students do not learn the proper social skills they need to develop early on. Children need to learn to interact with one another, and function properly in a social setting, they learn this primarily within the classroom, and if these classroom settings are altered by distance learning, then they will no learn how to function in the normal social school setting. Many critics also say that all schools do not have the appropriate technological support and infrastructure to make distance learning programs effective for students. Since all schools do not have the tools and financial means needed to establish and support effective distance learning programs, they would not be able to keep up with the advancing technology in education, and therefore their students would not receive the same advantages as other students in the schools around them (Ravaglia & Sommer, 2000). Greenwood (1998) states that schools using distance learning are just contracting out their educational responsibilities and that such courses result in the elimination of teaching jobs. He feels that by using distance learning to teach students, they are minimizing the teacherââ¬â¢s job of actually teaching the stud ents and designing lesson plans, and therefore slowly eliminating the need for teachers in the classroom at all. It is thought that there is more emphasis being placed on teaching than learning, and as a consequence schools are using distance education as merely a means to extend the classroom walls . While the critics of distance learning feel that this is just a way for schools to educate students, and relieve themselves of their responsibilities, there has been even more substantial evidence that these programs improve the elementary curriculum, rather than replace it altogether.

Nathan Bedford Forrest Essay -- Nathan Bedford Forrest Hero Bio Essays
Nathan Bedford Forrest à à à à à The United States Army, in its doctrine, lists nine basic principles. As stated in Field Manual 100-5 these include objective, offensive, mass, economy of force, maneuver, unity of command, security, surprise, and simplicity. 1 Napoleon had 115 maxims, Sun Tzu had 13 principles, but Nathan Bedford Forrestââ¬â¢s advice was the utmost of simplicity, ââ¬Å"Git thar firstest with the mostest men.â⬠2 As we look at the challenge facing our nationââ¬â¢s military today, our leaders would do well to look at Forrestââ¬â¢s campaigns and strategies as a guide. à à à à à . Forrest won respect for risking his life while trying to save his aging uncle. Subsequently, Forrest won the affection of Mary Montgomery who, in 1845, became his wife. à à à à à In 1851 Bedford moved to Memphis. He won several elections as an elderman and prospered as a businessman. When he closed out his business in late1859 war was eminent. He was involved in his own cotton business and was busy putting his family affairs in order. His net worth was 11/2 million dollars and he was netting $30 thousand a year for his cotton. While he was a slave trader during this period, Colonel Adair described his actions as ââ¬Å"Forrest was kind, humane, and extremely considerate of his slaves. He seemed to exercise the same influence over them that in a greater degree he exercised over the soldiers who served him as devotedly as if there was between them a strong personal attachment.5 On 14 June 1861, he enlisted in Memphis as a soldier in Captain Whiteââ¬â¢s Tennessee Mounted Rifles Company.6 This unit would become a subordinate unit of the Seventh Tennessee Calvary Regiment. Forrest was the unitââ¬â¢s commander when the war ended. Friends of Forrestââ¬â¢s approached Governor Harris and General Polk, which subsequently resulted in an authorization allowing Forrest to raise a battalion of mounted rangers. By October of 1861 he had eight companies of men comprising a total of 650. Most arrived with pistols and shotguns, as well as horses, which resulted in Forrest still attempting to obtain rifles for them when the unit was ordered to Dover as reinforcement for what was to be Fort Donelson.
