Human Resource Is the Most Important Assest in an Organization Essay Example for Free

Human Resource Is the Most Important Assest in an ecesis EssayHuman resources are the set of individuals who makes up the workforce of an composition, personal credit line sector or an economy. This resource resides in the achievement, knowledge and motivation of people and under(a) the right condition it improves in age and experience which no other resources can do. It is therefore considered the most productive resources that can create the longest advantages for an geological formation.For an organization to sustain and grow they do not only rely on advanced technology, good market placeing strategy and other factors etc. In fact, they stir to rely on their employee performance, contribution and image. As in most organization, they are mainly adult male orientated. Thus, without their support and contribution to the business operation, the organization daily business operation lead not be functioning thoroughly. Christina. P (2009) mentioned that organizational ps ychology holds that successful organizations do not owe their success solely to market realities and sustainable competitive advantages. Actually, there is a lot more. Successful companies are those that consider their homosexual capital as their most weighty asset. Facts and figures are the numerical elements of successful management, yet the qualitative, i.e. the cognitive aspects, are those that actually make or break an organizationHere are a few factors that explain how world resource can contribute to an organization to help them meet their future goals and expectations. Firstly, having strategic human resource planning. It is a process that identifies current and future human resources needs for an organization to achieve its goals. Reilly (2003) define human resource planning as A process in which an organization attempts to estimate the demand for get the picture and evaluate the size, nature and sources of supply which will be required to meet the demand. Without huma n resource planning, an organization may not be ready and well prepared for the future challenges ahead.Secondly, by having a unconditional working environment. In order to allow employees to contribute to the organization it is important to create a positive environment for the employees so as to ensure the smooth running of business of an organization. For instance, encouraging employee to go for lunch break on time, taking short breaks in between during working hours if there is too much stress, minimal overtime work. Such work practice will actually motivates employees to contributes more to the organization as they are not overwork or over stress. As mentioned by David.I (2009), work environment, employee satisfaction and employee turnover are three distinct concepts that are inseparably linked workplace environments greatly influence employee satisfaction, which in turn directly affects employee turnover rates. Knowing how to use a positive work environment to attach employe e satisfaction and reduce turnover is a key to developing a high-performance workforce.Thirdly, continuous learning indoors an organization. It is important for an organization to promote and level their employees of different level to attend workshops and courses. This is to allow employees to have an opportunity to learn new skills and to continue to upgrade themselves regardless of their age. Without the right knowledge or skill in a certain organization, employees may not be able to contribute to the organization more effectively. As mentioned by Robert J.V (2006), a learning organization embraces a culture of lifelong learning, enabling all employees to continually acquire and share knowledge. Improvements in product or service quality do not stop when proper training is provided to the employees. Employees need to have the financial, time and content resources available to increase their knowledge.Lastly, by having attractive benefits and compensation. Pay and benefits are t he most important incentives that organization can offer to employees in exchange for a more productivity and quality contribution to the organization. Employees should also be rewarded when they have accomplished a big assignment for their hard work and efforts to the organization as this attractive benefits and compensation will also help booze the employee morale. At the same time, they will feel appreciated by the organization where they may contribute more to the organization in future.If employees are not satisfied with the level of compensation or benefit, they may not be motivated to work and the level of standard for quality and productivity will definitely be low. As mentioned by Rebecca. L (2012), when your workers feel youre looking out for them, theyll look out for you, too, by producing higher quality work and staying in their jobs longer. Providing good benefits parcel of landswhich might include retirement, wellness care or dental plansis a tangible way to show empl oyees that you value them and their quality of life. Sure, the rising cost of benefits has made offering an attractive package more difficult for small businesses, but there are still ways to offer competitive packages to recruit and retain the best workers while staying within your budget.In conclusion, Human Resource is the most important asset of an organization as it plays an important role in every aspect .It is the backbone of an organization, without human resource the organization will not be able to function well and may not succeed in the future challenges.

Evaluation of Some Energy Drinks Essay Example for Free

Evaluation of Some dynamism Drinks EssayAbstract cogency drinks are beverages which transport chemical constituents that are give tongue to to improve physical and mental process. Most of them primarily contain varying amounts of caffein, guarana, ginseng and taurine. This orbit aims to provide a critical review regarding the adverse issuanceuate of excessive daily intake of zippo drinks. Five commercially available energy drinks were used as the subject of the study. The median(a) consumption of a veritable component was compared to the serving size included in each ware.It was effectuate out that the consumption of the ingredients to a greater extent than the recommended amounts per day may clear physiological case effects. There is no aesculapian use for energy drinks, however several ingredients in some of these drinks have been found to be helpful in the medical perspective. Keyword(s) energy drinks 1. Introduction In the past decades, the beverage industry paved the way to the rise of caffeinated energy drinks in the market. Back in early 1960s, it first of all appeared in Europe and Asia in response to the consumers demand for a dietary supplement that would result in increased energy (Reissig et al., 2009).Basically, energy drinks refer to beverages that contain mainly caffeine, alongside other active constituents which includes varying amounts of guarana extract, taurine, vitamins, amino acids and herbal extracts. These purportedly provide benefits such as increased mental alertness, physical endurance, performance and stamina (Simon and Mosher, 2007 Babu et al. , 2008). Conversely, there is inadequate evidence that consumption of energy drinks can significantly improve both physical and mental performance (Scholey and Kennedy, 2004).The all-inclusive availability and distribution of energy drinks makes them readily accessible for purchase by adolescents. Market surveys indicate that 31% of those aged 12 to 17 are unremitting c onsumers of energy drinks, as are 34% of aged 18 to 24 (Simon and Mosher, 2007). Concerns have been raised regarding the effects of the ingredients present in energy drinks on children and adolescents. This study was conducted due to the core objective of making the public aware of the adverse effects of energy drinks, especially to children. Adverse reactions and toxicity from high-energy drinks mainly al-Qaida from their caffeine content (Reissig et al. , 2009).The dark dose of pure caffeine in adults is 5 to 10 grams when taken orally and 3. 5 grams by injection. In children, the fatal dose is much lower (Health Canada, 2000). Children who consume too much caffeine are at higher risk for behavioral effects, such as anxiety, bodily fluid changes and loss of attentiveness. A daily intake of less than 45 to 85 mg is recommended, depending on the childs health condition (Health Canada, 2003). Based on a survey, it was found out that 42. 3% of the youth (ages 11 to 18) consumes en ergy drinks (ODea, 2003). At risk children having excessive daily intake of caffeine should be hold in to no more than 2.5 mg caffeine/kg body weight, and may need to avoid consuming energy beverages with higher caffeine content. Adolescents should frontier caffeine consumption as well as intakes greater than 100 mg/day for reports says that it has been directly correlated with an increase in blood force (Savoca et al. , 2004). 2. Materials and Methods 2. 1 Research Design The research is focused on the components of energy drinks where five products were sampled namely reaping A, B, C, D, and E. The researchers acquired a sample of each product. 2. 2 consume and Acquisition of Samples Products A, B, C, D, and E were randomly sampled.Fish bowl sampling was used where the names of these products were written on a piece of paper. Out of 7, 5 products of energy drink were picked from a bowl. Slovins formula was used and the margin of error was set to 20%. One out of seven is the p robability of each to be chosen. The 5 energy drink products were acquired through purchase. 2. 3 Gathering of selective information Each of the products underwent examining of the researchers. The composition information has been referred to for the determination of ingredients of each product. The data was listed and tabulated (Refer to set back 3. 1).This was do to compare their components and to determine which products share the same components. Nutrition information was besides included. 2. 4Analysis of the Components The ingredients of products were analyzed through research. The researchers studied the primary and side effects of some of the ingredients. The ordinary consumption of an average human of a certain component was compared to the serving size included in each product.3.

Common ingredients present among the energy beverages.Table 3. 1 shows the ingredients of products A, B, C, D, and E. Any formulated energy drink may contain the ingredients listed above. All 5 contain carbohydrates, particularly sucrose, and citric acid. Product C has the highest average quantity of carbohydrates which includes sugar, per serving with 54 g. It is followed by Product E with 39 g. , Product A with 34 g. , Product D with 26 g. , and Product B with 12. 5 g. , respectively. Product A, C, D, and E has Niacin, Pyroxidine Hydrochloride and Cyanocobalamin. Riboflavin is present in Product A while product E has Thiamine Hydrochloride.Vitamin B12, Cyanocobalamin, which is present in Product A, C, D, and E has quantities 2 mcg, 1. 3 mcg, 2. 4 mcg, 0. 70 mcg per serving respectively. In Vitamin B12 Dosing Guidelines for General Supplementation, the Recommended Dietary Allowances (RDAs) for vitamin B12 for 14 years old and above is 2. 4 mcg daily. An intake of one serving of Product D could supply the daily need of the body of an average teenager and adult while product per serving is 0. 83 % of our bodys needs for B12 everyday (http//women. emedtv. com). The RDAs indicate the adequate intake of a body for a nutrient.Panax Ginseng is found to be present in Products A, B, C, and E. This ingredient is claimed to play a role on mental, physical and sexual performance. It is said that it could lower blood pressure and hold up blood glucose but there is no current scientific eviden ce notwithstanding on its efficacy (Ernst, 2002). Up to 3,000 mg day of supplemental taurine is safe as considered (http//www. mayoclinic. com). Taurine is an amino acid that may lower blood pressure where systolic, diastolic and mean blood pressure in subjects with hypertension have been reduced by 6 grams of supplementary taurine every day (Kohashi et al., 1988).Taurine is present in Product A, B, C, D, and E. It is claimed to control hypertension yet there is insufficient evidence that it can significantly lower the risks of diabetes and epilepsy according to what it is claimed to be. The caffeine present in coffee and pharmaceutical drugs is said to be unhealthy. The caffeine naturally contained in a few herbs such as Yerba Mate, Guarana, Kola Nut, and Green Tea, is naturally occurring caffeine, also known as bio-caffeine and is non-addictive. Moreover, herbal teas are stimulants in nature due to other chemicals beside caffeine.These other stimulants found naturally occurring i n herbs, i. e. mateine (found in Yerba Mate), have similar reaction on the body like caffeine does, but they are not addictive at all (http//dherbs. com/). All products were found out to contain caffeine. But among the other products, only Product A has guarana extract (1 gram of guarana is approximately 40 mg of caffeine). Canadian Guidelines recommend an intake of no more than 85 mg/day for people with ages ranging from 12 years old and above. In a research conducted by Warzak et al. (2010), the hours of sleep is negatively correlated with the amount of caffeine intake.Consumption of caffeine may also affect cognitive decline due to its association with a wide range of clinical variables (Ritchie, 2007). Caffeine may cause a persistent effect on the neurochemical system (Sobotka, 1989). Caffeine on children with Attention-Deficit/Hyperactivity Disorder (ADHD) was more effective than no treatment in declining impulsivity, aggression, and parents and teachers perceptions of children s symptom severity, compared with Methylphenidate and Amphetamines (http//jad. sagepub. com/). Caffeine is a unbendable stimulant, thus it may reduce daytime tiredness and improve mental focus.However, researches are still a must regarding caffeines effects on the functioning of adolescents and adults with ADHD. 4. terminal After examining the ingredients of the energy drinks, the consumption of the ingredients more than the recommended amounts per day may cause physiological side effects. Caffeinated beverages, to be considered safe, must be limited of no more than the adequate intake of an average man, if a serving is formulated to be consumed once daily. Limited ingestion of these energy drinks most likely does not cause adverse effects.Energy drinks are composed mainly of carbohydrates and different ingredients like taurine, caffeine, and Panax Ginseng which are safe provided that it would be consumed in proper amounts. Caffeine, which is popular to many energy drinks, was fo und out to decline some behavior impairments associated with ADHD such as aggression and impulsivity.

With the rapid development of high technology, Internet media is emerging as the fourth. These resulted in to a greater extent frequent exchange of social information, and now advertisers have more agreeable channels for their goods and services promotion. Mass media has beseem a major promotional platform for ad both news and advertizement are interdependent and in return compete for the TV broadcast time and newspaper pages published. Advertising development is bound to have increasingly important influence on the development of good deal media.Firstly, this paper impart bug turn upline the question background and rationale. Fol down(p)ing this, it will explain the intention and the importance of the research. Then, it will explain the draw and the objectives of the research. Next, the paper will review old literatures which are related to this cartoon. This is followed by the methodology of the research. The paper will explain the resource, sampling and ethical considerations of the study orderly. Finally, it will make out the conclusion of the study.Background and research rationaleAdvertising is a particular need, since the production and exchange of goods, denote had began to be used in the life. The worlds first ad is conducted by voice, also known as oral advertising, which is the most primitive sell advertising, which is characterized by simple forms of advertising in particular. Back in the earliest slave society of ancient Greece, people do the slave and livestock trade by public advocacy and yelling out the rhythmic ads.The stratagem of the printing press created a new era of advertising. In 1473, Britains first publisher, William Kanke Si printed a lot of publicity religious content of the print ads and affix them in the many streets in London this is the first Western print advertising. In 1622, Nicholas Brown and Thomas Ke Qieer, who were both from the UK, founded the first English newspaperwhich was named hebdomadal News and was published in London. Since then, newspaper has become a main carrier of advertising.To the end of 1830, America has had about l200 pieces of newspapers, and 65 species of them are daily newspapers. close or first full-page edition of many newspapers is advertising. 1830 -1850 is the penny press era, because the price is a penny foe each piece of newspaper. Due to the low price, the sales had increased, and the effectiveness of advertising had also been increased. While popular in the newspaper ads, magazine ads are increasing, and a large amount of advertising agencies and advertising companies showed up since then.With the development and popularization of radio and television, they became a major carrier of advertising, because they have benefits of quick spread, vivid images and a wide range covering, which are more easily to attract the attention of consumers. After the 1980s, with the rapid development and popular of electronic media, computer began to be used for advertising design and planning. With high-tech, advertising has become part of the information dissemination activities in our lives. Inevitably, the development of advertising caused a lot of impact on atomic pile media, both positive and negative.Aim and ObjectivesThe aim of this study is to find the impact of advertising on the development trends of mass media, there must be a very complicated relationship between advertising and news in the mass media, and as all known, news provide real and quick information to people, but the function of advertising is all in all different, which will lead different impact on the mass media. This research is aimed to find out all the elements which cause t hese differences and the result in the final examination.This study will firstly introduce the original and historic development of advertising which takes the mass media as the major carrier, and then analyze the relationship between news and advertising on the aspects of their differences and common points, and find out how they influence mass media in different ways. In the following this study will explain the impact of advertising on the development trends of mass media, from both positive and negative aspects. Following suggestions which aim at improving the development of mass media will be minded(p) in the end of this study.Literature ReviewIn the study The impact of Advertising on media turn, Esther Gal-or, Tansev Geylani and Tubapinar Yildirim (2010) investigated how and in what extent the advertising affected the extent of bias in the media. They believed that, when making choices on which media to do the advertising and how much they would like to pay for it, advertis ers would evaluate both the size as well as the part of the readership of the different medias, in this way, when the total ad spending to a fixed advertising costs, it can be used as a reference value, check to advertisers strengths and weaknesses to make the final choice. They stated that, Reasons for the existence of media bias range from journalists desire to enhance their career opportunities to medias incentive to increase audience ratings. In a late paper by Mullainathan and Shleifer, a link is established between subscription fees and media bias.There are some people doubts the objectivity of the mass media when they are purchasing economic benefit. Serge Kasper (2008) pointed out in his weblog The Impact of Advertising on Society that, Critics has accused advertising companies of falsely using the power of sound and visual to convince unsuspicious buyers to purchase products that dont offer what they promise.John Harms from Southwest Missouri State University and Douglas Kellner (1990) from the University of Texas at Austin had cooperated a study Toward A Critical Theory of Advertising, in which that pointed out that The studies such as what stated before have explore how the mass media influenced by advertisers and business concern, which is reflected in news and cultural differences.. According to these previous studies, this point is just about inevitable. Chuck, Blore (2000), who is one of the partners of the advertising firm Chuck Blore Don Ruchman said that Advertising is the art of arresting the human intelligence just long enough to ingest money from it. And this determined that the advertising is totally different from news in the function and purpose when they are televised or published.Shah (2008) stated that, Since the emergence of mass media, business is very natural to take them as channels and platforms to the promotion of products and services, there is nothing wrong in this point, because it makes the share of information and i nnovation come aline and influence peoples daily life.MethodologyData CollectionThis paper studies the impact of advertising on the development trends of mass media, which requires doing some analysis on a common phenomenon for many advertising sector of media, and drawing basic conclusions. If only concrete on individual cases, apparently, the conclusion can not be model of all media in common. In this article, I will collect enough detailed information, and the questionnaire will help the final conclusion to a large extent. any the previous studies about advertising and media, as well as their relationship will be taken as useful data, and they will be self-contained and analyzed in a scientific way.Questionnaire InterviewIn order to collect quantitative data for this study, this paper will use structured, close stop and five-point method to design questionnaire correspond to previous literatures. Before carrying on the questionnaire, this paper will try to summarize as mor e as possible previous study on the relevant topic, and analyze the information from different angles. A set of questions will be distributed to 10 people whose jobs are relevant to media or advertising and to another 10 who are common audiences and readers. Also there would be 2 open-ended questions and some interviews to those recipients.Through the questionnaire and interview, those aims are expected to be realized1. Is the advertising also an important information resource in the daily life?2. Do people believe what the advertising tells about?3.

Finding expressions to close the gap between animateness expectancy from one race to the other may greatly contribute in making the U.S rank as one of the top nations in the western part of the world.One of my main reasons for selecting this topic was because I precious to take an in depth look by means of question and studies to find out why health inequality and disparity still exists in a great and rich country like the United States. In addition to that, my second point in selecting this research topic was to find out how at that place raise be equality amongst people living in urban and coarse areas in the U.S. when it comes to the area of health veneration. Even though over the age they abide been great improvements and minor changes there is still more work to be done in come in to make health and equality for all.Health should be a right for all, and not a privilege found on whether one lives in a rural or urban area, or whatever socioeconomic status they may occupy. One should pass the rights to view as the same privileges. One of the huge differences when looking at health disparity is sprightliness expectancy age between white, black, and African males, and black, white, and African American females. For example, the life expectancy for an average white male is 76.7 years old while on the other hand for an African American male the average age of life expectancy is 67.8 years old. Comparing the two ages there is a difference of 8.9 years between a Caucasian, and an African American male. later looking at the difference one may ask themselves these questions they are all American why can one race live longer than the other? This is a question I adjudge asked myself before, however taking this class through the semester helped me to understand why. Baer mentions, African Americans experience about 67,000 more deaths than they would have h ad their mortality rates been similar to whites. This translates into 2.2 million more years of life lost. One of the main reasons for this is that most Caucasian males live in an urban area with good jobs, good incomes, good health insurance, and access to good doctors, while on the other hand, an African American male living in a rural area does not have access to health insurance, does not have a good job, or does not have access to a family doctor. This may lead to a dope of accent to an individual which may cause incompatible diseases such as chronic heart disease, hypertension-which may lead to stroke, heart attack, and renal failure. This in turn may lead to premature death of an African American male. These results are the same for women also. As stated by, premature mortality (75 years of age) is greater rural residents than among urban residents, and rural-urban mortality differences vary by age. ill-timed death and mortality is one of the key issues when taking a look at health and inequality in the United States. Nevertheless, another subject to well examine is how health and diseases are not distributed fairly. Individuals who live in rural areas are more likely to amaze a disease than one who lives in an urban area. This also contributes to the soft of health individuals may ache. For example, diseases like tuberculosis would be common in a rural area because of the life way of life one may live, the kind of income they may earn, and the health care they may be take up could be totally divers(prenominal) than the one they receive in the urban area. According to, (levy and Sidel) The cause of some(prenominal) diseases are complex interplay of multiple factors, many of which are due to social injustice. For instance, Caucasians receive more attention and care when they visit a doctor which may lead to a wide variety of issues. However, the one that stands out the most is because the color of the individuals skin, he/she may be looked at differently, or not implementn the same care a Caucasian would have received.The subject of disparity and inequality does not only gunpoint with adults, it also reaches down to children. Unfortunately it is a subject that affects all ages from infants to adulthood. In just about cases there have been findings that when it comes to certain(prenominal) diseases and long term infirmaryization, infants whom their parents are of different social class or race are treated differently and are cared about differently than kids that are Caucasian, or not minorities. While doing my research for this project I was amused to find out the inequality and disparity comes down to this level that even infants are cared for differently because they belong to a certain minority group. As I have stressed out in my paper and continue to do so, I really believe that everyone should have equal access to health care regardless of their differences. In one of my articles it takes and in depth look at ho w childrens asthma hospitalization and urban areas in Texas are different. Grineski mentions, It talks about how poor children are dispropriately affected as they have higher asthma prevalence rates (and more servere asthma) than non poor children. I put to issue forthher this to be a very interesting finding that areas where poor children and non- poor children were living would affect their health. This could be because of several(prenominal) reasons, for one it could be because of the demographic area or the type of housing conditions in which these infants live in. All these factors could play a big part in contributing to the findings that kids in rural areas are more probable to get Asthma.However, there are also many other factors that also contribute to health disparities. There are socioeconomic factors that let in the individuals race, ethnicity, the kind of education they may have, and the kind of income they earn annually that also contribute to the individuals health. As mentioned earlier, the individuals health may allow him/her to receive a different treatment from another individual whom is of a different race. For example, John, an African American male, goes to slang his doctor because he has been coughing for a week and wants to get examine out. Instead of giving John all the different tests, the doctor would just furnish him medicine and tell him he just has a cold or flu, yet if it is a white male they would probably give him a thorough check up to see what was really wrong with the individual, and then give that person the necessary medication they need.Also, ethnicity brings an additional dimension to health disparity. As mentioned earlier, when it comes to health care for minorities they generally have a harder time getting the kind of care they need, especially ones that live in the rural areas. Baer mentions that, Health disparity research suggests that ethnic minority groups like African Americans, Latinos, and Native Americans s uffer a triple burden in seeking health care 1. They are significantly less likely to have health insurance than whites, and so accessing care is a major challenge, and while enough acute care is hard enough to come by, preventive care is all but impossible for those who are insuredThe kind of education one has also contributed to the gap between health inequalities between individuals. The more education one has the longer they live, and the healthier life style they have. This is mostly due to the fact that the higher education you have the higher income one may get, and the better education one may get the more likely the individual may have a good job with great security which helps to provide financially for their families. The less education they have the less they can earn, the more stressful the job can be, and the less job security they have in order to provide for their families. Also, the more education you have the more educated you become about living a healthier life style. For example, eating healthier by getting good nutrients and a having a good diet is smart, but in order to live this kind of life style one must be able to pay it which does not allowed everyone in the United States to have this opportunity. Kaplan states, On this view, we can understand why controlling for the SES and education reduces the health disparities between blacks and white Americans but does not eliminate them. Because black Americans are also systematically disadvantaged with respect SES and education and because SES and education are associated with health outcomes in the United States.another(prenominal) deterrence that also brings a problem to health inequality and disparity is the environment one lives in. The environment we live in plays a big role on the kind of diseases we get and develop. Plus, the area one lives plays a big part in the kind of health care one receives. For example, one living in a rural area may not have access to a hospital, or the righ t doctor they may need to help them give them the right attention they need to live a healthier life style. An additional thing that plays a role on the kind of health we get from the environment could be the kind of water one has access to. The kind of water people in rural areas may use may have things in it that are not healthy for one to drink and may cause different kinds of stomach viruses or stomach problems. The kind of food individuals get in the grocery store maybe not be as healthy as the ones individuals from urban areas may get. Some food may support more fat and carbohydrates, than the ones they have in the grocery store in urban American cities nationwide. According to McElory and Townsend, That changes in components of their model (e.g. new subsistence patterns) can cause in balances in the other components ( e.g. new subsistence strategies can lead to exposure to new risk ), and a very severe imbalance to generate stress and disease. As the above quote points out, health inequality and disparity can be a big part of the kind of environment one lives in. After selecting this topic I wanted to personally drive through the urban and rural areas of Fort Wayne and compare the differences. Hartley mentions, Traditional concerns as to access to primary and hospital continue to dominate rural health policy. As I drove through town I observed a few things. One ceremonial was that there were barely any hospitals in the rural area. I found a couple of clinics but all the major hospitals, and big health facilities were located in the urban areas. In my opinion, this is a huge disadvantage for someone living in a rural area in Fort Wayne. Another thing I observed during my drive was that there are far more liquor stores located down south. For example, you can drive down a block and you can see three or four liquor stores by the time I was done driving through the block. In contrast, up in the urban areas there are liquor stores but not as many as the o nes I came across while in the rural areas. Another thing I also noticed while I was doing my observation was that the urban areas are well taken care of. The streets are clean, buildings were in good order done, and roadstead were done properly with no dirt on the streets. Yet in the rural areas the opposite was true. There were several buildings that were left unfinished roads were not as clean, housing areas were not as properly done as the ones done in urban areas in Fort Wayne. These are several inequalities I observed on my own. It was a firsthand experience, and I was very shocked to find out that such things are going on in our on back yard here in Fort Wayne. I believe that in order for us to address this problem as a nation we must first focus in our own cities and towns and then work our way up.Individuals in rural areas have been accustomed to receive unfair health care attention that people that live urban areas in the United States are used to recieving. As mentioned e arlier in my paper this not only a problem in the United States but a problem that is effecting millions of other continents around the world. Joyce and Bambra state that, Despite overall improvements in health outcomes since the second world war, health inequalities between the best and worst of society are persistent in developed nations and in some in some instances are continue to widenAs a community how can we address health inequality and disparity in our communities to help this stigma get away? Studies have definitely shown that they are minor improvements that have taken place over the years, but never the less, as a community we have a lot of work to be done. Hartley mentions, Recent trends in rural health research and policy suggests that effective policy interventions must be based on differences among rural regions. When arguing for progressive rhetoric for rural American, rickets noted that Urban-Rural comparisons. One of the first things I think we need to do as a co mmunity is first try to improve our rural areas. The next step I believe we should do as a country is have a universal health care program in place where everyone leave be able to have insurance for every citizen in the United States. In making health insurance accessible to every one in the United States any person will be able to receive the health care they need. An additional thing we as a community need to do in order to address health inequality and disparity is to have more hospitals in the rural areas and not just in the urban areas. We need to have hospitals and clinics more accessible to them. So if they need to see the doctor they do not need to make a fifteen to twenty minute drive they can have it right in their neighborhood.I firmly believe education is the key to removing health inequality and disparity from our communities. The better we educate individuals that are of a different race, socioeconomic status, and ethnicity, the more adequate a person knows about how to live a healthy life style and eat properly. We need to get them to exercise more in order to live healthier, and also educate them about the effects of smoking cigarettes and what it causes. For example, have health fair programs that will tell them how smoking can cause lung cancer, and many other chronic diseases, and also better educate them how drugs and sharing needles can affect ones life style and cause many diseases such as HIV-which is a very serious epidemic that is killing millions of people in our world today. Also having different organizations that are pro-health that would go into the different rural communities and talk and teach individuals on what they can do to live a good and healthier life would be a great asset in educating individuals.Another way for us to draw the gap when it comes to health and inequality is to create more jobs for individuals, so that they will be able to work and support their families. In doing this it will give them something to stre ss less about, which in turn will help individuals to be stress free. As mentioned earlier in my paper, stress causes a lot of health issues which can lead to different cardiovascular heart problems, effect once growth, diabetes, and hypertension which are all various disease one can get from living a healthier life style. So hopefully creating more jobs in rural communities may be able to create a less stressful life for individuals.Improving the environment are also ways in which we can address health disparity in our communities and country. For us to take the next step in which we can overcome health disparity and inequality is to clean up the rural areas. They should be cleaned up, they should also have access to clean water to drink, and tap water should be sterilized to certain standards to meet the States regulations. Also fountains and lakes should be monitored and kept clean, having clean water is cardinal in other for mosquitoes and other parasites to not take over rural communities. Not having all these necessary steps taken people in rural areas may have easy access to malaria and other diseases which may greatly affect their community.Doing away with majority of the liquor stores in rural areas will also help to bring inequality to our neighborhoods, because having alcohol in rural areas in my opinion just helps to destroy the individuals in these areas. Drinking may also contribute too many other diseases that may cause premature death in one area. Another substance that we can do away with is creating sentiency about drinks and get them off the streets. In getting both drugs and alcohol out of the rural areas we can only hope that we can try to get the rural areas to be almost equivalent to urban areas although one that will not be easy to do.In doing the following we can hope that health inequality and disparity in rural areas can be improved to met the standards that urban areas have. The U. S is such a wealthy nation that they should not b e anything such as health inequality and disparity amongst different areas in the . From my research I do however believe that there is hope for the future. Changes are been made however, we just have to put our differences apart in other for us to reach the point where health is equal and available to everyone no calculate how much income they make, the amount of education they have, or the color of the skin they should have access to it .Overall, I learned a lot of from this project I gained a lot of knowledge from it. I became aware of things that I was not previously not aware of in the past. I never looked at health as inequality and disparity I rather looked at it from a different prospective but in doing this project it made me understand what it means when one mentions the United States health care system has inequality and disparity in its system. From doing this project I also gained passion for this topic and down the road I would like to volunteer, or be health activist s, because as repeated earlier in my paper I believe health services should be offered to everyone.

It takes the current of one voltage and converts it into a unlike voltage. The beat of transferred energy from Primary circuit to the Secondary Circuit is equal, and the losings be ignored. The frequency of the circuits does not diversify but the voltage and current of each of the individual circuit is changed, it is increased or decreased, un little we use the transformer as a one-to-one isolating transformer.Basic on the wholey, the transformer perform the portion of changing electricity from gritty to low voltage by making use of the pursuit properties of electricity.Magnetism is always present near in an electric circuit.Magnetic field is always changed by c hanging the strength or moving the conductor therefore voltage is induced.Voltage is known as the government note of the Force or Pressure that is apply to push the electrons around the circuit. electricity at a higher voltage goes in the transformer and runs finished the large number of ringlet butterflys that are wounded around the iron core. As the current is changing, the core magnetism will also be changing. A wire with less coils around the iron core is known as the output wire and the changing magnetism produces current in the wire. When the number of coils are less that means less voltage and more coils means more voltage. in that locationfore, the voltage is either stepped down or stepped up according to the number of coils in the wire.A common transformer involves a ferromagnetic core which ensures that values of magnetic magnetic field linkage remain high. But there are some factors related to the ferromagnetic stuffs that are trustworthy for part of the loss assoc iated with military force transfer. These losings are as follows1. Core lossesCore losses groundwork be classified as the sum of eddy currents losses and the hysteresis loss.Hysteresis lossEnergy that a magnetic material soaks in cannot be recovered completely. Core of the material is excited by an A.C source, the flux tautness rises and falls with the magnetic field strength or current which is basically sinusoidal. When the magnetizing current increases the flux density also increases but there comes a point after which if there is any further increase in the current, flux density is saturated. If the current is reduced from the saturation point to zero, flux density will start to decrease. When the value of the current reaches upto zero the flux density should also become zero but it does not become equal to zero. whatever of the flux density will nonoperational be present in the material for the zero current, which is called as a residual magnetic flux. Thus, the total cen tre of energy used to magnetize the material cannot be recovered back and this energy is trapped within the material core and is dissipated as a form of arouse. Area of B/H curve gives the hysteresis loss, larger the loop the greater the energy removed to create the magnetic field.Eddy current lossesIf a coil is wrapped around a core make up of some material and an A.C source is applied to circuit, eddy current losses take place. As the come out to the coil is changing or alternating which produces an alternating flux in the coil. The varying flux in the core induces e.m.f in the core material due to which eddy currents start to flowing in the core material. Therefore, the energy is lost or dissipated in the form of heat because of eddy currents.The laminations in the core can reduce the eddy current losses. Thin sheet steels which are separated from each other must be used because these insulated sheets reduce the centre of the current flow and hence the eddy current losses.2. Copper lossesCopper loss occurs when the transformer is loaded, the excitant precedent is dissipated as heat in the primary and secondary flatuss of the transformer because these windings have internal resistance. When the load is low, the amount of heat produced is small but at high scads the amount of heat produced becomes significant. Construction of Single-core three- degree double wound TransformerA single-core three-phase double wound transformer consists of three sets of primary and secondary windings, individual set winded on each leg of the core made up of iron. The windings consists of turns made up with the insulated wire. These coils are then mounted on a magnetic core material in such a way that the magnetic flux produced by one coil increases and ensures that the most of the magnetic flux links with the second coil so that mutual induction is being increased. The coils are spaced 120 degrees apart. The transformer is filled with a dielectric oil and thus provide in sulation in-between the winding and case. These windings are either connected in star or delta configurations.Delta ConnectionDelta system proves excellent for distribution system for short distances. These types of transformers are used in neighbourhood and commercial loads of small magnitude near to the substations. There is one kind of voltage present between the 2 wires in the delta system. This system is shown by a Triangle. The voltage between any two wires will be the same and from each individual point of the Triangle, wire emerges which represents a three phase. superstar ConnectionsFor a star connection, voltage of two lines is the same as the voltage on a 3 phase system. In Star connection, each of the windings are made up connecting each individual winding end to end and this point is the star point or neutral point of connection winding. Connection for neutral and 3 phase connections are then taken out of transformer. Applications of TransformersTransformers in Electri cal EngineeringAn electrical engineer may put a transformer in a circuit for many reasons. If the whatchamacallit being powered require higher power than what is available locally or the powered device needs frequency matching, a transformer is placed in such circuits. For example signal and audio transformers are used to couple amplifiers and microphones to the input of the amplifiers.Power UtilitiesWhen driving through a rural area, power polls and overhead power lines can be seen and transformers are placed on these power polls by power utilities. Utility substations make use of transformers to deliver power of certain usable level and quality to consumers and businesses.Power Generation and dispersionElectrical power is generated at the power station and this electrical energy is then transferred to the consumers through high tension power lines. To distribute the electricity from the power station to the consumer, different transformers are used in stepping up and stepping d own the voltage up to the certain level.Commercial useEvery electrical device uses transformer in one way or another. Almost every commercial building has at least three or four large high power transformers in order to provide required voltages to operate overhead lightning system, telephone system, heating, operating electrical equipment in labs and much more.Transformers in homeThere are a lot of transformers used in many appliances at our homes that require different voltages for their operation. Electric appliances like dishwasher, washing machine, microwave and fridge require comparatively high voltages between 110 and 240 volts, the devices like laptops and charger mobile phones and MP3 players require relatively low voltages. A laptop charger requires up to 15V go mobile phone charger requires up to 6V and M3 chargers require up to 12V to charge up their batteries. Thus, these appliances have small transformers built in them which convert the domestic supply of 110-240 volt s into a low voltage that they require for their operation. Power Transmission and Distribution SystemThree-phase system is used in power transmittance because less amount of conductor is used to transmit electrical energy to different places.Three conductors carry 3 alternating currents peak values of which reach at different intervals of time. If a conductor is taken as a reference point, there is a delay of time by one tertiary and two third of a cycle of the current for the remaining two currents. Because of this delay in the available phases, constant power is transferred over each cycle of current.There can or cannot be a neutral wire in three-phase systems. Neutral wire is used to allow a higher voltage while still supporting the appliances operating at lower single phase voltages. As loads can directly be connected between the phases so there is no neutral current wire in high voltage distribution.There are many factors that make three-phase system very desirable and test ed in electric power systems. In a load which is linearly balanced, the phase currents cancel each other and add up to give a zero which also helps in eliminating the neutral wire. Phase conductor carry same amount of current which means that they all can have a same size of conductor for balanced conditions. Moreover, the transfer of power in the system is constant for a linear system, it reduces the vibrations in a system. GenerationElectricity is generated at the power station at around 10kV by rotating a coil in the magnetic field. In power stations, all the generators are synchronized so that they all produce electricity that oscillates together. For more efficient generation, three windings are used on the generator to produce three-phase electricity.Sources for power generation For distribution, the following types of resources are available for the generation of the electricity.Conventional MethodsThermal energyThermal energy or the Nuclear energy is used to produce steam fo r the turbines that drives the rotating AC generators to produce electrical energy.Hydro-electricPotential of water is stored at a higher altitude and is made passed through the turbines which in turn drive the generators.Non-Conventional MethodsWind powerWinds blowing at high speeds are used to drive the turbines that are coupled to the rotating AC generators. TransmissionTransmission has an important role between the production of power and the usage of power. Transmission lines carry high voltage electricity over long distances from power shows to the consumers. Once the power is generated. It is send to the substation in the power plant where the voltage is stepped-up using step up transformer for transmission purposes.When the voltage is stepped up, it helps in the decrement of the transmission losses. It is then sent to the power system station from where it is further familial to different cities.Why there is a need to step up the voltage for transmissionFor transmission o ver long distances, transmission lines are made up of conducting materials like aluminium and power loss is always associated with these conducting materials. This is because if the current through the wire is I and the resistance of the wire is R then an amount of electrical power I2R is dissipated as heat. This will result in a much less power at the receiving end than the actual power generated at the station.Thus, when power is transmitted at a high voltage, wires of low current carrying capacity are used so there is no need of thick wires that cost considerably high instead they can be replaced by thin wires that cost less. DistributionSubstations reduce the voltage of the electricity from the transmission lines. The power grid is connected to the different parts of the country and it distributes the power in different cities through transmission lines.The transmitted power from the power grid is stepped-down to 110,000 volts from 230,000 volts using a step-down auto transforme r. Then for the distribution of power for industrial uses, the power is again stepped-down to 11,000 volts from 110.000 volts by step-down transformer located in the streets. This reduction in the voltage increases the current in the wires and thus the losses but greatly reduces the cost of power poles and increases the safety.The distribution substation further reduces the voltage to 230 volts or 440 volts for the local transmission for domestic purposes depending upon the need of the user. Some business and houses require two or three-phase power supply while the others only need single phase supply. Operation of the transformerTransformer works on the principle of mutual induction. jibe to Faradays Law of electromagnetic inductionRate of change of flux linkage is directly symmetricalness to the induced emf in a conductor or coil with respect to time.When primary winding is connected to a voltage source, an AC flows through it and which produces a continually changing magnetic f lux that surrounds the winding. This changing magnetic flux flows to the secondary winding as some flux from primary winding will be linked to the secondary winding. As magnitude and direction of the flux is continually alternating, change of flux takes place in the secondary winding. According to Faradays law of electromagnetic induction, this changing magnetic flux produces an induced electro motive force or simply the voltage in the secondary winding of transformer therefore, a current start to flow if the circuit is closed.The rate at which the flux changes depends upon the amount of the flux which is linked with the secondary winding of the transformer. Therefore, it is important to link all the flux from the primary winding to the secondary winding of the transformer. It can be done by putting a low reluctance path which is usually common to both of the windings and that low reluctance path is known as the core of the transformer.Three-phase conclusion MotorIntroductionElect ric ram is a device which performs the operation of converting electrical energy into a mechanical energy. The induction locomote is known as a three-phase AC motor which is widely used in the industrial applications as they areSelf-starting.Their construction is simple and compact.Less expensive.Require minimum amount of maintenance.More reliable and highly efficient.Additional starting motor is not required and do not required to be synchronised.Induction motor is also known as asynchronous motor. Due to inductive coupling, the generated electromagnetic power is transferred to the secondary winding. These windings are being separated by air gap between them.The induction motor consists of a Stator and a Rotor. The motor frame is permanently attached with windings of very low resistance. When current and voltage is applied to the terminals of Stator windings, a magnetic field is produced. Applications of three-phase induction motorInduction motors are most demanded motors in the industry. Some of their applications are given belowIndustrial drives make use of 3 phase cage rotor motors because they are pretty simple, efficient and are not costly.Single phase induction motors are used where the load is comparatively smaller.These motors are being

Soda bottle rocket :: essays research papers

Soda bottle rocketPurposeThe students pull up stakes check out the effect of the rocket length upon the keep of flight. The students allow also investigate the push-down list upon the outer space flight.BackgroundThe students will proof Newtons third rectitude of motion states that for every action there is an equal and mated reaction. Newtons third law also applies to rockets. A rocket gets its lift from the gases pushing out of its tail. The run of the rocket pushing on these gases is the action force. The gases exert an equal but opposite force on the rocket, which forces the rocket up, this is called the reaction force. According to the original guide sheet, the two items NASA will be evaluating the rocket on will be distance flown and time aloft. A two liter bottle with a cone and fins. The time is measured by seconds that the bottle flays, starting when it lives from the launch pad until it rites the ground. The distance is how far it flew. The motion will be projecti le. The average velocity will be the total distance of rocket sting measured. The average speed will be the total distance of rocket flight measured in meters and total amount of time aloft measured in seconds. The altitude will be measured by an altimeter. The acceleration will speed up and change direction. The force can be the gravity. The ki plunderic energy will be the mass and velocity. The potential energy on the launch pad. Newtons first law is about the state of motion of an target does not bloom as long as the net force acting on the object is zero. His second law is about the acceleration of an object is equal to the net force acting on it divided by the objects mass. Newtons third law is whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. The momentum is mass velocity. The kinetic energy is the mass velocity. Momentum is a property of any moving object. For a slow moving object it is given b y the mass times the velocity of the object. For an object moving at close to the speed of light this definition gets modified. The total momentum is a conserved quantity in any process. Weight is the upright force exerted by a mass as a result of gravity.

The Underworld as the Key to Living the Greek Life Essay -- Odyssey

The Underworld as the Key to Living the Greek vitalityBeyond relaying a fantastic journey, featuring a glorified hero who embodies to matinee idol Greek ideals, Homer uses the epic books of The Odyssey to explore all the nuances of Greek culture.
