Aviation and Climate Change Essay Example | Topics and Well Written Essays - 1000 words

Aviation and Climate Change - Essay Example Due to increase in number of fights, aircraft emissions can affect climate considerably. Carbon dioxide and water do so directly, others effects like production of ozone in the troposphere, alteration of methane life time, formation of contrails and modified cirrus cloudiness, are indirect causes. The emissions that can affect stratospheric ozone i.e. nitrogen oxides, particulates and water vapors, do so indirectly by modifying chemical balance in the stratosphere. Airports growth again is directly affect the climate because expansion or growth of airport need space and may destroy the ecological balance of the place in particular and have overall impact in general. Manchester airport, which accounts for almost 8.8% of UK civil air transport movement, generates proportion of the pollution from UK aircraft. It would translate into 88,000 tones of carbon from its civil air traffic alone (Manchester Green Party briefing on Emissions charging at Manchester airport, 2nd edition, December 2003). Assessment of Cost-benefit: The ground traffic stimulated by the airport results in emission increase. Manchester airport has experienced increase of almost double number of passengers in last 10 Years, this has increased the frequency of flight to, and form Manchester with the existing felicities at the airport but due to this congestion has increased. Due to increase in air traffic Manchester airport operator experienced, increase in its income considerably. Growth in the earnings of airport was due to more landing, parking charges etc. directly and customer inflow indirectly increases the earning. In comparison to other major airports in Europe, Manchester experience little growth in terms of numbers of runways. Due to congestion, cost of flying could not be quantified directly. Now it has been increased almost to double. It has been calculated that average direct cost to the airline of every minute that an aircraft was delayed is 21.80 pound/passenger in 2002. If we calculate co st of delays for Manchester airport where average delay is around 13.1minute with 175000 flights with 23.4pound/ minute, it costs 53 million pound (http://www.caa.co.uk/docs/80/airport_data/2002annual/Table_04_1_Air_Transport_Movements_2002.pdf .). This is direct cost of congestion. Congestion and delay costs the passengers heavily. This delay and congestion cost do not include the environmental cost incurred. However, there are also indirect costs of delays. Environmental/climate impacts: Congestion also has negative environmental impact as more and more planes are forced to burn more fuel for longer as they delayed on runways or circulating around airports, leading both to increased carbon emissions, additional aeronautical noise and lower air quality for local residents. Surface congestion around airports as both passengers and staff travel to or from the airport can have similar environmental impacts as well as economic costs. These costs to three other significant environmental impacts arising from air traffic i.e., aeronautical noise, local air quality and emission of greenhouse gases affecting climate change. One of the major area where air transportation affect, is the more use of aviation fuel. It consumes almost 13% of fossil fuels used in transportation. The amount of CO2 formed from the combusting of aircraft fuel is determined by the total amount of carbon in the fuel because CO2 is an

Peter Matthiessen Research Proposal Example | Topics and Well Written Essays - 500 words

Peter Matthiessen - Research Proposal Example (Commire, pp. 27-28) Other than fiction, he has proved to be a master with his nonfiction writings. For instance, the 1975 shootout of FBI and Native Americans were examined in the year 1983 by Matthiessen in his book, In the Spirit of Crazy Horse. (McKay, pp. 28-30) However, Peter Matthiessen acquired a more natural place for himself in midst of other novelists through his travel writing that renounced him as a complete advocate of natural world. (Bonetti, pp. 35-37) In the year 1978, endangered creatures and spiritual development was lyrically analyzed by him through his book, In the Snow Leopard that provided him with the National Book Award. (Howard, pp. 56-58) In the year 1991, his African Silences explained his trekking experiences in African and Antarctica regions, which was followed by his another book, End of the Earth in the year 2003 that recounted the same experiences. In addition, the protection of majestic cranes and ecosystem of the earth was encouraged by his book, the Birds of Heaven in the year 2001. Until now, the paper has briefly discussed some of his renowned books that have recognized him as a living legend. (Kibler, pp. 92-93) Peter Matthiessen has also completed documentaries on different films, one of which is Blue Wate r, White Death that was a film related to the natural world, one of his favorite themes. (Nicholas, pp. 17-18) One of the major characteristics of Peter Matthiessen is his scrupulous and thorough approach to the topics that are considered during his writings. American Indian issues and natural history are some of his frequently focused topics since fifty years. Now, the paper will discuss his personal life and career, which will be followed by a brief conclusion. On May 22, 1927, an American naturalist and living legend was born in New York City that was named Peter Matthiessen by his parents. Peter Matthiessen is credited for more than twenty non-fictional and fictional books, and has been one of the

The Advancement Of Technology And Construction Industry Construction Essay

The Advancement Of Technology And Construction Industry Construction Essay 2.1 Introduction The construction industry recently dominated many changes due to the advancement of technology, the industry needs to work collaboratively and pool knowledge in order to capture innovation. Its a common dilemma in the construction industry: how to capture knowledge and transfer it from one job to another, where there will be innovation among the talented personnel. Constructing Excellence, though, has come up with an innovative ground-up way of boosting RD and innovation. The construction process of today is in need of improvement. When comparing the construction process of today with the aspects that are considered necessary for the innovation process, it is clear that there are problems in the sector that to various extents hinder innovations. According to Kristian Widen the construction sector is blamed to be over conservative and low on innovation. Many different types of actions have been initiated depending on what is believed to be the problem. Generally Innovation in construction can be studied from many different perspectives. Traditionally, innovation in general has been studied from either an innovation systems perspective or from the single innovative company. Simplified, innovation systems research deals with how the different companies, government and other institutions relate to each other in the innovation superstructure, while research on the company often deals with its innovation capabilities, strategies etc. These different ways of looking into innovation have taken place in the construction sector as well over the years. There have been a number of studies covering, for example, how national research policies support construction innovation and how projects should be organized. The construction industry is generally driven by single projects that require the creation of a team to do the work and the subsequent dissolution of that team once the job is completed. This can both enable and constrain innovation. It enables innovation by ensuring great flexibility and fast adoption of new ideas and technology, but it can also constrain innovation as much knowledge gained through the process of a project is lost as the business moves on to the next project. Developing a strategy for learning within your organization can help overcome the potential problems of lost knowledge. Documenting lessons learned and best practices after every project can be a useful way to avoid previous mistakes and learn from experience. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ 2.2 Review of the literature 2.2.1 Construction Innovation The need for innovation in the construction industry has long been stressed from both within and outside the industry. Changes in global markets, increased customer expectations, and government pressure have all led to innovation becoming a key focus for the construction sector. To echo this, a recent government report claims that Innovation needs to be at the heart of the construction industrys efforts to improve productivity and develop new capabilities, business and markets. Innovation in construction is considered to be the act of introducing and using new ideas, technologies, products and/or processes aimed at solving problems, viewing things differently, improving efficiency and effectiveness, or enhancing standards of living (The Civil Engineering Research Foundation (CERF), 2000, p. 2). It is increasingly recognized that innovation is not an orderly or neat process, but a process that is disorganized, controversial, and uneven that competes with the day-to-day business and everyday constraints of your business. Therefore, a conscious strategy to manage innovation is crucial in order to spot opportunities and convert these into growth. Generally there is no clear definition of the concept innovation. Many different varieties and also different models exist. For instance Innovation is the process through which firms seek to acquire and build upon their distinctive technological competence, understood as the set of resources a firm possesses and the way in which these are transformed by innovative capabilities (Dodgson and Bessant, 1990, p 38). Similarly its also defined innovation as Innovation means the application of new knowledge to industry, and includes new products, new processes, and social and organizational change (Firth and Mellor, 1999, p.199), It is when an act, as an idea, begins to impact on its environment (Atkin, 1999, p.4). A technological product innovation is the implementation/commercialization of a product with improved characteristics such as to deliver objectively new or improved services to the customer. A technological process innovation is the implementation/adoption of new a significantly improved production or delivery methods. It may involve changes in equipment, human resources, working methods or a combination of these. OECD, 1997, paragraph 24) A technological product innovation is the implementation/commercialization of a product with improved characteristics such as to deliver objectively new or improved services to the customer. A technological process innovation is the implementation/adoption of new or significantly improved production or delivery methods. It may involve changes in equipment, human resources, working methods or a combination of these. OECD, 1997, paragraph 24). Construction Innovation The construction innovations occur in different ways in the organizations, where some times we see they are common models take place in the organizations, while some times innovations occur in different models. Most business drivers to the need for the construction industry to put stronger focus on innovation, and one of the best series documents illustrates the recent attention that has been paid to this subject( Gann and Slater, 1998; Slaughter, 1998; Winch, 1998, Aktin, 1999; Gann et al., 2000; Koskela and Vrijhoef,2001). Drucker defined innovation as the effort to create purposeful, focused change in an enterprises or social potential. Others also defined innovation as innovation is defined as generation, acceptance and implementation of new ideas, processes, products or services (Thompson, 1965) or the successful implementation of creative ideas within an organization (Amabile et al., 1996). According to the previous studies there are five models suggested by Slaughter, namely incremental, modular, architectural, system and radical innovations, by using these models of innovations companies can plan their implementation activities with respect to timing of commitment, coordination among project tea, special resources, and level of supervisory activity. The definition provided by Slaughter (1998) is broadly accepted by participants and academics. She defines innovation as follows: Innovation is the actual use of a nontrivial change and improvement in a process, product, or system that is novel to the institution developing the change. Innovation in the construction industry can take many forms. Slaughter (1998) characterizes such innovation according to whether it is incremental (small, and based on existing experience and knowledge), radical (a breakthrough in science or technology), modular (a change in concept within a component only), architectural (a change in links to other components or systems), or system (multiple, integrated Innovations). Apart form that, its increasingly accepted that construction innovation encompasses a wide range of participants within a product system (see, for example, Marceau et al., 1999). The construction industry is being increasingly challenged to successfully innovate in order to satisfy better the aspirations and need of society and clients and improve competitiveness (Latham 1994; DETR, 1998). Its also very important to consider the existing literature on the broad topic of construction innovation drivers and their operation in a variety of countries (see Blayse and Manley 2004), with the contributions of four authors standing out: Seaden (e.g., 1996), Winch (e.g., 1998), Slaughter (e.g., 1998; 2000) and Gann (e.g., 2001). These authors appear to most effectively mobilize expertise based on both the construction industry literature and the innovation literature. However, despite the significant contributions of these authors, there remains an opportunity to contribute to the literature by exploring construction innovation benefits, using Malaysia construction industry as case. Construction innovation as a field of study has generated a number of useful critiques of the industrys performance, the higher the levels of innovation in the construction industry, the greater the likelihood that it will increase its contribution to economic growth. The innovation processes always takes place but with out notice and the companies in the construction industry are interested innovative technologies in order to be competitive in todays market. In order to be clear with the above mentioned models, firstly we must understand the differences between innovation and invention, invention is a detailed design or model of a process or product that can clearly be distinguished as novel compared to existing arts. Innovation, on the other hand, is the actual use nontrivial change and improvement in the process, product, or system that is novel to the institution developing the change (freeman 1989). Generally the innovations has its benefits to the construction industry, commonly the innovations increase economic growth (Schumpeter 1934), apart from that the innovations also increase the productivity and efficiency (Schmookler 1952), innovation can also be associated with market growth, through the provision of new or improved products and services and reductions of cost of production. On the other hand construction-related innovations can also have significant social benefits (Seaden 1996). There are many attempts to define innovation within the industry, and one of the most comprehensive definitions was given by Ling (2003) and could be considered as the most comprehensive within the construction industry context. He defined innovation as an implementation of new idea to a construction project with the intention of deriving additional benefits, although there might be some associated risks and uncertainties. The new idea may be refer to new design, technology, material component, or construction method used in a project. (Asad et al., 2005). Models of Innovation Incremental and Radical innovations Incremental innovation is a small change, based upon current knowledge and experience. In contrast, a radical innovation is a breakthrough in science or technology that often changes the character and nature of an industry. While incremental innovations occur constantly, radical innovations are rate and unpredictable in their appearance and in their impacts. A radical innovation creates a new way of understanding a phenomenon and formulating approaches through which to solve problems (Nelson and Winter 1977; Dosi 1982). Modular and Architectural Innovations According to the previous studies, there is distinction between modular and architectural innovations, for instance the modular innovation entails a significant change in concept within a component, leaves the links to other components and systems unchanged, while Architectural innovation involves a small change within a components and systems (Henderson and Clark 1990). On the other hand Modular innovations may be developed within an organization and implemented with a minimum of negotiation with parties involved in the development or selection of other components; where as architectural innovations require change and modification in the set of interacting components and systems (Afuah and Bahram 1995). System Innovation System Innovation is also very important among the models of innovations, its identified through their integration of multiple independent innovations that must work together to perform new functions or improve the facility performance as a whole. For this kind of innovations the linkage are explicitly among the innovations, as well as entailing changes in the links to other components and systems (Cainarca et al .1989). The previous papers highlighted that the construction innovation offers the potential for significant company, industry, and societal benefits. As the demand rises for increasingly complex facilities, and the traditional sources of construction materials and labor shrinks, most construction related companies are looking for design and technology innovations to improve their products and services, and decrease their costs. The five models of construction innovations suggested by Slaughter are basis for construction companies to plan and carry out activities to effectively use specific construction innovations. The above models are based upon current theories in management and economics, but are modified to reflect the special conditions associated with constructed facilities.

Womens Roles During Times of War and Virginia Woolfs Three Guineas Es

Women's Roles During Times of War and Virginia Woolf's Three Guineas With the prevalence of war goddesses in most traditions from China to Greece to Ireland, women have been separated from the front lines of war for centuries. The goddesses, the divine representations of women in the ideal, are torn between dual roles: that of Minerva, the goddess of wisdom and just war, and that of Vesta, goddess of hearth and home. These two roles, warrior and mother, are not necessarily as very different as they might appear at first glance. Western tradition claims that women are not made for war, but for household work: sewing, cleaning, cooking, and looking after children. Society told women to carry brooms in lieu of swords; to collect firewood instead of ammunition, and to keep house rather than protect a nation. Yet, for centuries, women have fought their peoples' wars, even if they never lifted a sword or fired a rifle. Yet, in Virginia Woolf's book, Three Guineas, she claims that women do not actively participate in war. She tells the reader, "To fight has always been the man's habit, not the woman's" (Virginia Woolf, 6). She proceeds to explain that women have been set in a world apart from men. According to Woolf, men and women exist in separate worlds, coexisting, but not interacting. Women live outside of the masculine spectrum of official schooling, professions, and, of course, war making. I beg to differ. Women have always interacted with men and live in the same world as their masculine counterparts even when it comes to schooling and professions, but especially when it comes to war. Women have always joined their brothers in the trade of war making and to deny their efforts and victories is to deny a great portion of his... ...ese troubles side by side and together rather than as two separate peoples who happen to exist near to one another. It is as Benjamin Franklin said of the American Revolution: Better that we all hang together for we will surely hang alone. Works Cited: "AAS Online Exhibitions: A Woman's Work is Never Done."

Men are from Mars and Women are from Venus Essay

According to John Gray, men and women completely differ in their style of communication which corroborates the illusion that they are from different planets. However, their communications style differs and they work and be trained to become accustomed to these communication perspectives to live and work together in harmony. Women are more emotional than men and hence men used to mock the girls irrelevance talks. Actually women are termed as a weaker sex as they always want men to respect to their feelings more particularly about relationships, other personal problems and about family matters. In such matters, women expect that men will respect their feelings by extending emotional support and understanding. Relationships end in catastrophic disaster when each other does not understand each feelings and emotions. When the relationship ends in serious disaster, the women have to understand that man is completely diverse from everything and she has not accustomed to and tried to adapt to the differences in her relationship. Communication between men and women are so diverse that it takes many years for a complete understanding in a relationship. Even insignificant resemblance in communication style that binds a couple together while one tries to iron out the larger differences. In ordinary life, it is an established fact that men wants to be respected and women wish to know whether they are being truly loved by men. A successful couple is one who is able to achieve this and in such cases no doubt, good communication will be the end result. Thus, John Gray’s assertion that men and women are from different planets in terms of communications is really a convincing one. Thus, communication between men and women are pursued through two languages. The male language is used as a general warning that he is in a cave or on his path to the cave. Gray here uses cave to describe the ways and means men use to iron out their differences or to deal with an issue. When men face some problem, they wish to be alone or in his cave in complete solitude. [Gray, 1993, p. 22]. However, the reaction of a women will be completely different if they face with issues and when communicating with their spouse. As per Gray, women employ metaphors, superlative and poetic licenses to express their feelings. Moreover, there are chances that men may misunderstood this poetic licenses expressed by women. [Gray. 1993, p. 17]. It is the exact scenario where men and women ignore to appreciate the exact significances of the each other expressions and due to this, Gray has introduced Venusians / Martian dictionary in his book. This dictionary could be much help to iron out these misunderstandings in associations and relationships. According to Gray, men and women communicate in different languages and hold opposing views. Many common people are of the view that Gray’s metaphor is having more relevance and match their very own experiences on the subject. According to Gray, women have to gain knowledge of men before fostering a successful companionship. [Gray, 1993. p. 21]. Likewise, when men are disturbed or strained, they automatically keep silent and return to their cave to sort the things out. [Gray, 1993, p. 21]. Women at this juncture understood that his spouse wants to be alone to sort out things by himself without her interruption. Further, Gray is of the view that there is a need for men to know that women like to share and communicate things through in a more non-solution and in a complex way. [Gray, 1993, p. 35]. There is a complete need on the part of men to aware that women also long that their feelings and emotions are to be honored when they are upset, depressed and troubled and it is duty of the men to make her more comfort and to assuage her feelings in such scenarios. [Gray, 1993, p. 35]. As Gray details it, his book is for the people who wish to have an appreciative feature of gender associated with their counseling. Gray’s objective is to assist women to appreciate men and to take the ignominy out by counseling and by assisting men to have a more constructive approach to therapy as ‘even healthy relationships need a counselor. Gray longs to be a worldwide translator between Venusians and Martians. He has not indulged in the argument that one is superior to the other but stresses that they are dissimilar. Thus, Gray summarizes his views: â€Å"It is time to appreciate and authenticate gender variances. Do not try to change the attitude of one’s partner. Men have to seize the situation and understand and women should acknowledge and appreciate the things which men does and if he feel appreciated, he will no doubt listen. Gray is of the view that even though the customary function of contributor and nurturer may be often changing, women and men still have fundamental hormonal variances. However, due to rapid transformation, women have crossed over in the man’s world and hence the two worlds have come together now. If one has great appreciation of how these people in different world imagine and act, one will have a real harmony but not a friction. According to Gray, men and women have varied and complimentary emotional requirements. One can define a man’s sense of self through his capability to get results while a female’s sense of self is explained through her feelings and eminence of her relationships. Hence, women expect that her feeling shall have to be respected and honored while men demand that his feelings have to be appreciated and respected. Gray is of the opinion that rubber band theory well explains the metaphor of male intimacy cycle. As men experience the need for autonomy or independence, they draw away as rubber bond do when it is stretched to the limit. Men will pull back with power and spirit as rubber band do if they are given opportunity to move back to their positions or caves. If women demand that men should be intimate and close all of the time, they will become flaccid and limp, by losing their power and strength. [Gray, 1993, p. 35]. Gray book emphasizes diverse of theory. Gray could not able to offer no more plausible explanation other than his planet metaphor on men and women relationships. Gray tries to illustrate the basic differences that exist in men and women characteristics. Gray has cited examples like men disgust to demand for directions as it would put them down while women not at all prefer it. Men longs to talk in public as an exposure of their sound knowledge remains mum at home whereas women tries to express their feelings in home rather than in public places as their main objective of their intimacy. CONCLUSION: The reader of the book will understand that men and women communicate in different languages and hold opposing views. Readers will appreciate that Gray’s metaphor is having more relevance and match their very own experiences on the subject. No doubt, communication plays very significant role in men and women relationship. If one tries to honor and respect the feelings of spouse, there will not any marital issues at all. I would recommend that all who in the phase of establishing relationship and those are already tied their marital knots should read the book to lead a pleasant, happy married life. The readers of the book will understand that â€Å"It is time to appreciate and authenticate gender variances. Do not try to change the attitude of one’s partner. Men have to seize the situation and understand and women should acknowledge and appreciate the things which men does and if he feel appreciated, he will no doubt listen. Gray is of the view that difference between men and women are consistent and are of more biological and natural. Thus, Gray book seems to emphasize and respect the male and female differences.

Kill and Odysseus Slaughters Bunches Essay

Mrs. Heimes English 9D 25 January 2013 Odysseus: Zero or Hero? Odysseus, saves citizens, saves shipmates, is a cold blooded killer and promiscuous man. When I think of Odysseus I think of a criminal or a zero. Odysseus is a zero for three main reasons 1. He is a killer and does not protect his shipmates 2. He is not a team player and he is not a leader 3. He constantly shows he can not be trusted. â€Å"There will be killing until the score is paid† is a quote from Odysseus in book 22. Everybody knows that heroes do not kill and Odysseus is no exception. In book 22 Odysseus slaughters bunches of men because they pursued his wife Penelope. On page 960 the blue text reads Odysseus and his men are compared to falcons who show no mercy to the flocks of birds they pursue and capture. These men were killed terribly because they pursued Odysseus wife because Odysseus was gone for 20 years. When Odysseus’ men were going to go straight to Scylla Odysseus did nothing. â€Å"She ate them as they shrieked there, in her den, in the dire grapple reaching still for me†. While Odysseus’ could have warned them of Scylla Odysseus decides that their lives are not very important. Because of Odysseus’ actions all of his men died. Since the the dawn of time it has been a universal fact that to be a hero you need to be a team player. When Odysseus gets his shipmates killed it is a perfect example of Odysseus not being a team player. Odysseus is the only person survive from his expedition why because he did not properly protect his shipmates. Let me read this quote â€Å"Driven by hunger they ignore Odysseus’ warning and eat Helios’ cattle†. Odysseus’ could not properly feed his men and he could not control them. When you look at the cyclops cave situation you realize that Odysseus is not very clever or smart. One of Odysseus’ men say â€Å" Take the cheeses, get them stowed, come back, thrown open all the pens, and make a run for it†? While doing that was clearly a better choice Odysseus’ refuses and decides that he wants to meet the cyclops. This is not a good Idea for many reasons the first is what could or would the Cyclops do for them. Every hero has to show that they can be trusted and depended on. While Odysseus did make it back to his homeland he also got all of his shipmates killed. The deaths of all of Odysseus’ shipmates came from a fault from Odysseus. Odysseus alone survives† Page 937 blue text. Odysseus constantly is unfaithful to his wife but after 20 years when his wife Penelope is looking for a suitor Odysseus kills all of the suitors. In this moment Odysseus shows me that he is not only a hypocrite but a killer. As I state in this paper Odysseus is a zero and clearly not a hero. Things like being a killer being untrustworthy and being a bad leader do not add up to Odysseus being a Hero. Things like saving lives being trustworthy and a good leader are things that do add up to being a hero and Odysseus is none of these.

buy custom Health Care Policy Brief essay

buy custom Health Care Policy Brief essay Prevention/Reduction of Childhood Obesity in Shelby County, Tennessee Obese and overweight children constitute about 30 percent of American children. Since this is a big number, pressure is mounting on the entire public health care system. However, the levels of obesity vary from one county to another making it necessary to employ specific measures in specific places. Therefore, I take this opportunity to propose a bill on the prevention and reduction of childhood obesity in Shelby County, Tennessee. It should be noted that medical expenditure on childhood obesity in Shelby County has risen almost tripling in the last two decades. The persistent increase in these medical expenses is becoming a heavy burden for the taxpayers. Apart from the cost burden of childhood obesity for the taxpayers, obese children are exposed to the risk of developing chronic diseases and psychological problems. Such children may develop a variety of diseases including high blood pressure, sleep apnea, heart diseases, and diabetes. These chronic diseases are among the leading causes of death in Shelby County. Approaches that Can Be Used to Solve Childhood Obesity in Shelby County, TN I acknowledge the fact that the Shelby County Government has dedicated its efforts and resources to deal with childhood obesity through various pieces of legislation. However, the intensity of the situation calls for the use of more approaches including but not limited to the following: Introducing nutrition education in the early school years; Enacting a legislation that stipulates the type of school nutrition; Introducing thorough physical education programs in schools. Introduction of Health Eating Education in Schools Education is purposed to impart knowledge in people in a variety of areas. However, more emphasis has been put on exposing children to knowledge that would enable them to contribute to stabilizing the economy and being self-reliant. In the area of nutrition, children are mainly taught on the different types of nutrients that are contained in different types of food. Students should also be taught on the proportions that they should take in. They should understand that when they take in more nutrients than their bodies need, the excess is converted and stored in their bodies. Children should be made aware of the health benefits of healthy eating habits (Moss, 2014). Such strategy will work best if healthy eating is incorporated into te school curriculum. The weakness of this strategy is that it will increase the syllabus workload. Therefore, it is bound to face opposition from teachers and other educationists. Enacting Pieces of Legislation that Regulates Schools Nutrition It has been observed that consumption of junk food has risen to quite high levels in the past two decades. Such phenomenon has been observed not only in Shelby County but also in other parts of the country. Fast or junk food is rich in fats, which makes it dangerous when consumed in high amounts. It also lacks fiber and therefore, go through the digestion process considerably fast. Organism copes with the high speed of digestion by storing more of what is eaten. Most children prefer this type of food since they find it tastier. Thus, they have to be monitored to ensure that they do not exclusively feed on it. Therefore, schools that have breakfast and lunch programs should mainly provide students with vegetables, fruits, and other types of food that is rich in fiber such as whole grain baked products like brown bread. According to Centers for Disease Control and Prevention (2014), this approach was enacted school nutrition legislations in 2011 in Massachusetts and Mississippi, and it has registered success in those states. The weakness of this strategy is that it may interfere with childrens preferences. Therefore, it is likely to face opposition from the children. Introducing Mandatory Physical Education Programs in Schools In 2008, the USA Department of Health and Human Services issued guidelines on physical activity for the American citizens. The department recommended that people engage in rigorous but enjoyable physical activity for 60 minutes daily (Lavie, 2014). However, people have not been keen on observing the recommendations of the Department of Health and Human Services. For instance, some schools in Shelby County have not been closely monitoring students physical activities. Therefore, education officials should ensure that all schools set a side time for physical activities and that learners are supervised during such sessions. The fact that almost 30 percent of children do not exercise even as few as three days a week is worrying. Schools opt to set aside for exercise because physical education is costly and diverts attention from academics at the same time. Shelby County education officials should appeal for a budgetary allocation to fund physical education. Although all the states have their own standards of physical education, more sttill has to be done. The weakness of this measure is that it has cost implications. It requires more funds to initiate and therefore, will face opposition from parents and the government. Conclusion The National Institutes of Health, National Heart, Lung, and Blood Institute (2014) concluded that enacting a legislation that stipulates the type of school nutrition is the most recommendable measure to take. Therefore, specifying what children should eat both at home and in school would largely help reduce childhood obesity. Besides, children need help in making choices and therefore, the decision on the appropriate food cannot be left to them. Besides, children are generally active and do not require pushing all the time to participate in physical activities (Centers for Disease Control and Prevention, 2014).
