Vitamin D Essay Example | Topics and Well Written Essays - 2000 words

Vitamin D - Essay Example se is of course individuals that live in far northern latitudes where temperature concern requires these individuals to remain thoroughly covered so that frostbite and/or exposure to inclement weather is not affected. A secondary group of individuals that is negatively impacted by the degree and extent to which they are able to gain healthful level of exposure to the sun, in order to encourage the body to create vitamin D naturally, are those individuals within societies that are relatively wealthy and spend the majority of their time indoors. However, there is a third contingent of individuals that must be considered with respect to low vitamin D levels and the impact this on out. These are with regards to women that live within conservative Muslim nations in and around the equator; specifically Saudi Arabia. Accordingly, the following analysis will focus specifically upon the difficulties in achieving sufficient levels of vitamin D for female stakeholders within Saudi Arabia, some of the means by which diet can be leveraged as a function of promoting vitamin D levels within the human body, the effects of vitamin D deficiency, and ways to raise awareness with regard to the impacts of low vitamin D levels. Firstly, with respect to low vitamin D levels that are represented within the female population of conservative Muslim societies, this is oftentimes the result of the fact that strict norms of morality prevent women from showing anything more than their hands or a brief space around the eyes. Whereas it is not the goal of this particular paper to discuss whether or not the niqab is ethical or moral, in a universal standpoint, it must be noted that these moral restrictions create a situation through which vitamin D creation from the sun is nearly impossible (Vanni et al., 2014). As women remain cloistered behind layers of dark fabric, the overall amount of time that they are able to spend outside, or in public in general, is restricted. Furthermore, the extreme

Theory in Research Paper Example | Topics and Well Written Essays - 750 words

Theory in - Research Paper Example In essence, the development of nursing theory relies on the amount and type of research that has been conducted in this field (Fitzpatrick & Wallace, 2006). In the nursing profession, there are many theories that help explain clinical occurrences, thus, helping nurses during practice. 2. Relationship between Nursing Theory and Research Hall’s theory of core, care, and cure is one of the theories that have contributed greatly towards successful nursing practice (Fitzpatrick & Wallace, 2006). Care is about the pro-active bodily care given to patients, which leads to good patient-nurse relationships. Core, on the other hand, involves the use of communication to get information from the patient about their health status. Finally, Fitzpatrick & Wallace (2006) state that the element of cure involves the administration of medicine and other forms of cure that are necessary for the patient’s wellbeing. In this theory, therefore, nursing is involved with attending to the person, through communication, taking care of the body through hands-on attention, and combating the disease through medical procedures involving drugs and other forms of treatment. ... Nursing theories are useful to practitioners in terms of providing descriptions, explanations, and predictions for clinical events. However, circumstances do not always allow people to exercise all these recommendations, causing diseases and injuries to occur. When this happens, nursing intervention is required to help the patient regain good health. In this theory, the nurse establishes a good relationship with the patient and helps them coordinate their daily activities so as to re-establish proper healthcare. Analyzing the contributions that the two theories make to nursing practice, it is evident that none of theories can provide the basis for research on its own. While Orem teaches about how nurses can facilitate self-care, Hall is more focused on how overall care should be provided by nursing professionals systematically. This goes to show that nursing should be based on a number of theories, in order to come up with comprehensive results. 3. Definition of Terms A case study is a methodological research conducted on particular entities, over a specific amount of time, with the aim of solving a problem and demonstrating a given hypothesis. Ethnography is a type of research conducted in order to investigate how human beings behave in their natural setting. It analyses such aspects as culture, behavior, and norms, which influence human behavior. As a research method, grounded theory deals with a study of how social interactions among people contribute to the formation of meaning to certain aspects of life. This theory aims at analyzing which particular processes within the society affect the majority, and what those processes are. Phenomenology is a study of

Pros And Cons Of Wind Power Environmental Sciences Essay

Pros And Cons Of Wind Power Environmental Sciences Essay Wind power has been used by people throughout history and converted into usable energy. Small windmills have been providing power for rural homes throughout the world since almost a hundred years ago. They were used for powering water pumps and also converted wind into useable electricity for homes. In the 1930s, programs to bring electricity to more remote areas extended the electrical grid system to these areas causing windmill generated power to gradually be replaced by electricity generated by power stations which burnt fossil fuels such as oil and coal to generate electricity. This eventually caused the disappearance of windmills in rural areas. However, in recent times, new more modern and advanced wind machines are beginning to appear on the landscape of many regions of the world. Discovery of windy rural areas has enabled people to harness the power of the wind in much larger quantities than ever before. Through technology, it is possible to now generate clean, cost effective, and renewable energy. This could range from a single turbine powering a single landowners home and facilities, to large scale wind farms which could supply power to the grid itself and in turn provide electrical needs to hundreds of homes. Advancement of technology and it declining cost makes wind generated electricity more competitive with fossil fuel generated electricity. The cost of wind generated electricity has decreased greatly since the beginning, and it is estimated that wind power supply ten to twenty percent of electricity needs in the United States could within three to four decades. Despite these the impressive advantages of wild resources, it is still only in an infancy stage in many parts of the world. Only recent pollution laws, increase in fossil fuel costs and the fear of the exhaustion of fossil fuels have led to the intense development of wind power. Wind energy has many advantages, for example, wind is free and with modern technology it can be captured efficiently. Wind is naturally produced when there are pressure differences in the air above the earths surface. When air gets heated up, it rises creating a low pressure area. Cooler, high pressure air from the surroundings the rush in the take its place. This creates wind. This is especially true in coastal areas due to the fact that water takes longer to heat up as compared to air, therefore resulting in a great difference in pressure between the air above the water and land, which results in exceptionally strong winds. Mountainous areas also have strong winds that could potentially power wind turbines. As different slopes are heated at different times of the day, pressure differences are created in the mountain range creating wind. In certain instances, the shape of the mountains and valleys may also act as a funnel, causing the wind to accelerate to higher speed as the approa ch these areas. Once wind turbines are built in place, the energy they produces do not cause green house gases or any other form of pollution. This means that with time, the operation of the wind turbine would actually make up for whatever carbon footprint it has left because of its construction. The power produced by the wind turbine over time would exceed what was used in the form of fossil fuels, and raw materials during it construction. Given enough time, a wind turbine would actually pay for its own construction and maintenance through the revenue it generates by producing power. Although wind turbines often reach up to above 50 meters tall, each single turbine only takes up a small plot of land. This is due to advancement of technology where thanks to modern materials and designs. Wind turbine towers are and with space aged materials which are strong and light and designed to have minimum drag resistance. Also because turbines have to be spaced a certain distance from each other, the land in between them can still be used for other purposes such as farming or even for building homes. Remote areas which are located far away from the main power grid can use wind turbines to produce their own electricity. Just a few wind turbines could potentially supply power to a small community located far away from the power grid, saving the cost of extending the grid to the community. Wind turbines are also available in many different sizes. This means that people from all walks of life can make use of wind turbines be it for personal use to supply electricity to a single home or to supply power to business or even small town or villages. As wind occurs all over the world, there is no place in the world that the power of wind cannot be harvested. This could be an advantage for third world countries where there is no electricity supply. Since wind turbines only require an initial start-up cost and minimal maintenance cost, it could be possible to provide electricity for poorer settlements or countries. However, the strength of wind will almost never be constant. It varies from nothing at all to storm force. This implies that wind turbines will not be able to produce consistent electricity at all times. There will even be times when it produces on energy at all. Due to this, the wind turbine has to be located in a location where there is enough wind so that it would be able to run at energy producing speeds for most of the year. For this to happen, many factors have to be taken into consideration. Wind speed data has to be recorded for a specific location at least a year to ensure that the wind conditions would be suitable for building a wind turbine. Other factors that have to be considered include any obstacles that the wind may encounter before it is able to reach the turbine such as buildings and trees. Location of wind turbines due to their nature would usually have to be located in open areas. This in turn brings other difficulties such as ease of transportation of materials to the build site and connection to the power grid. Furthermore locations with the highest winds are usually costal areas. Building offshore wind turbines, although does not require any land space, is very expensive to build due to the extra structural reinforcements needed to build standing structure in the ocean. Many people also feel that the countryside should not be spoilt by building large structures would reduce the aesthetic appeal of the environment. Conservationists also oppose the building of wind farms for fear that they may kill of interfere with wild life such as migratory routes of birds. Wind turbines, depending on perspective, are noisy. Each turbine generates about the same level of noise as a car travelling at approximately 70 miles per hour. Therefore if there are homes located near the wind turbine, residents may be disturbed by the noise generated by the wind turbines. During the manufacture of wind turbines, pollution is also produced in the form of energy consumed for fabrication of materials and pollution produced by vehicles used during the transportation and building of the turbines. Therefore it cannot be said that wind power produces no pollution at all. Finally, if an entire communitys needs were to be provided by a single wind farm, the wind farm itself would have to be extremely big considering that the largest turbines available today would only be able to power just under 500 homes. If a town or city of 100, 000 homes were to run on solely wind power, then a farm of almost 200 turbines would be needed. Taking the distance needed between each turbine, then an immense area of land would be needed just to power this town. After considering both advantages and disadvantages of wind turbines, I have come to the conclusion that although it is impractical and unrealistic to supply the entire worlds power with wind power, it is a highly efficient way of harnessing free energy from the environment. If as much available space as possible were to be used as wind farms, coupled with other renewable energy sources such as solar, bio-fuels, and hydro-electric power were used to substitute fossil fuels whenever possible, then the impact on the environment would be greatly lessened. This would greatly reduce the usage of fossil fuels, thus giving researches more time to come up with solutions to the worlds energy needs without relying on fossil fuels which will eventually run out and also how to reduce the load of burning fossil fuels on the environment.

The Body Essay -- Sexuality

The social and cultural conditions in which we live in today continue to perpetuate and maintain the rape culture that pervades our lives, especially for the lives of individual women. As a feminist thinker, Ann Cahill works to change this by challenging current definitions of rape as assault, and addressing questions of why rape exists in the first place, and how we can begin the prevention process. In Cahill’s book, â€Å"Rethinking Rape†, she approaches the subject of rape by analyzing the works of contemporary feminist theorists like Judith Butler, who perceive the female body as a potential site of resistance against gender-based oppression and a â€Å"larger system of sexual domination† (Cahill 32). Although each is addressing very different issues in feminist theory, Cahill does draw upon some of Butler’s ideas about the imitation and performance of gender in Butler’s essay â€Å"Imitation and Gender Insubordination.† Cahill does t his in order to further articulate her critique of â€Å"the body† and the role it plays in the phenomenon of rape â€Å"as an embodied experience of women† at the level of the individual (Cahill 109). There are certain concepts besides the performance of gender that both Authors touch on including â€Å"the body†, heterosexual norms as inhibitions to attaining liberation, the relationship between sexuality and gender, and the problematic nature of social constructs. By comparing and contrasting the works of Cahill and Butler, this paper will explore the importance and complexities of â€Å"the body†, the pivotal role it plays in Cahill’s critique of the phenomenon of rape, and how Butler’s critique of â€Å"coming out of the closet† values the notion of gender â€Å"performativity† more than the notion ofâ€Å"the body† itself. Before de... ... feminine body so we internalize that ideal and subject ourselves to the â€Å"intrusive, expensive, and high maintenance practices in order to be rendered beautiful† (Cahill 155). There are a number of factors that play into the perpetuation of rape culture, the hierarchy of gender, and gender performativity. The one thing they all have in common that is essential to understanding how men have been able to oppress us for so long and continue to oppress us. â€Å"The body† is the one thing that can maintain our inferiority and powerlessness, but it can also be the one thing that can free us from the same system of oppression.

Pepe Jeans Case Essay

The main advantage of Pepe not carrying inventory is obviously the cost savings, as it is usually not efficient or cost effective for that matter, to carry excess inventory. The downside is not having enough pairs of jeans on hand to ship to stores when demand is high. An inventory would help alleviate this. The six month lead time is both an advantage and disadvantage for Pepe. The long lead time is positive in that once a retailer places an order, they only have a week to cancel the order. Pepe is able to realize a profit after only ten days rather than months later. The contract locked retailers in immediately and keeps them from reneging on the deal. The downside is that many stores may be turned off by the long lead. It was mentioned in the article that most manufacturers have lead times of a few months or less. The independent stores also tended to order less volume due to the inflexible order system, and the trouble with fashion is that items typically have a short wearable life before they go out of style. Corporate purchasers were worried that the jeans they ordered may go out of style before they even arrive. If I were the manager of Pepe, I would assure my retail partners that every reasonable action was currently being taken to help reduce the current lead time. I would mention the options being considered and thank them for their partnership. I would then sit down with the CFO as well as the best analysts in the company and run reports to forecast the most efficient method of reducing lead time. The case mentions two alternatives to reduce lead time: working with a Hong Kong sourcing agent or building a finishing operation in the UK. Without seeing the company’s financials, it is difficult to say which would be a better choice. The article does mention that Pepe has no long term debt and appears to have plenty of cash on hand. If that is truly the case, then the better option may be to invest in the finishing factory. There would be a large investment up front, but lead time could be cut in half while reducing costs by up to ten percent as well. On the other hand, the sourcing agent could possibly reduce lead time down to as little as six weeks. The problem with this option is that costs to soar by as much as thirty percent.

An Overview of the Life of John F Kennedy

John F. Kennedy was one of the most liked and dedicated presidents of the United States of America. His presidency ran The second of nine children, John Fitzgerald Kennedy was born in a three story wooden house on May 29, 1917; in Brooklyn, Massachusetts. His parents were Joseph P. Kennedy and Rose Joseph Kennedy intended for his sons to receive the finest private school education possible. Johns education started at a private Dexter school in Brookline. During fourth, fifth, and sixth grades John enrolled at Riverdale Country Day School. At the age of thirteen, John entered the Canterbury School in Milford, Connecticut. The spring of 1931, John suffered an attack of appendicitis. He had to stay home and rest for the remainder of the school year. Kennedy†s† parents decided to hire a tutor to help him catch-up during the summer. John passed Math, English, and Latin. When he finally recovered completely, he entered Choate, a fine prep school in Wallingford, Connecticut. When John graduated from Choate, in 1935, he planned to study for a year at Londons School of Economics. Then at eighteen years old, John came down with an illness called Jaundice. In the fall, John joined his friends, Lem Billings and Rip Horton at Princeton University. He later had another attack of Jaundice that forced him to miss school for one semester. Johns father then encouraged his son to enter Harvard University in the fall of 1936. John graduated from Harvard in 1940, with a degree in Political Science. He then entered Stanford University in California. While there he studied Economics and tried his hand at writing. During this time, the war was raging in Europe. John decided to enlist in the Navy on September 22, 1941. He served four years and was ischarged when the war ended in 1945. At 28 years of age, he was heading for a successful career as a newspaperman. His father began pushing him towards another career— Politics — He believed that since Johns older brother was dead, that it was his responsibility to run On January 3, 1947, John took the oath of office as a US Congressman. Later, in 1952, Kennedy decided to run for United States Senate. In 1953†¦. Kennedy decided to marry and wed Jacqueline Lee Bouvier. He was 36 and she was just 24 when they were married in a Roman Catholic ceremony. Later that year, John began suffering terrible back pain. In 1955, he underwent surgery to repair a spinal injury. While recuperating, he wrote a book called, Profile in Courage The book was about American Political leaders who defied the publics opinion to vote according to their consciences. For this work, he received the Pulitzer Prize. He then returned to his political career. Although John barely lost the Democratic Vice-presidential nomination in 1956, his overwhelming re-election as Senator in 1958 helped him towards his goal of becoming a Presidential Candidate. In 1960 John Fitzgerald Kennedy became President of the United States. At 43 years of age, he was the youngest man to ever hold this title. On November 22, 1963 John was 46 years old and just ending his third year as President. He was just planning his campaign to run for a second term as President. On this date, John and his wife, Jackie, flew to Texas to take part in his political tour. After there arrival, they got into the back of an open limousine with Texas Governor, John B. Connally and his wife. About 12:30 Mrs. Connally remarked, â€Å"you certainly can†t say that the people f Dallas haven†t given you a nice welcome,† as people lined up everywhere. Before Kennedy could respond, a shot was fired. From a sixth-floor window. a sudden rifle shot rang out, fatally wounding the president, a second shot hit the Governor, and a third shot struck Kennedy in the back of the head, causing his death. At one p. m. , that same day, reporters rushed from the hospital to spread the horrible news. As a victim of assassination— the President of the United States was dead. The whole country mourned the death of J. F. K. Those who knew him or knew of him will forever remember this wonderful man.
