The Unhealthy Diet of College Students Essay -- Expository Research Es
The Unhealthy Diet of College Students People eat food every day without thinking twice about it, because it is a necessity for us to live. How often do you think about what is in the foods that you eat? How many calories does it have? Are there any vitamins and minerals in it? Is it high in fat? For most of us and especially college students who live a busy life on the go, the answer to that question is probably no. Since becoming a recent graduate of Indiana University of Pennsylvania Academy of Culinary Arts, I have been more interested in food and what people are eating. Also since more young Americans are becoming obese I want to find out what they are eating and where. Going to college and seeing how students have poor eating habits I want to find out why they are eating this way. Is it because they are away from home for the first time? Or is it because that is the only food that is available for them? I also want to find out if students would eat healthier if it was provided for them? My hypothesis is that students eat unhealthy because it is more convenient for them. There is usually no time to cook a homemade meal and most college students are always in a hurry so it is easier to pick up takeout. Also most college students donââ¬â¢t know how to cook. I also believe that most college students donââ¬â¢t care if the food is unhealthy for them, as long as it tastes good. Hopefully, in the following pages I will uncover the wide world of college eating. The research methods that I used for this paper were surveys, interviews and observations. I performed a survey on ten college students in which I asked various yes and no questions and ones with various multiple-choice answers. Do you have a meal ... ...omething to go. I found out that college studentââ¬â¢s want foods that are quick, taste good, and cheap. The limitation to my research was that I only passed out ten surveys all at the cafeteria. Perhaps if I did more or passed them out at a different location I might have gotten different results. I also only interviewed two people, and a larger sample might have changed my results. Also only observing my roommates shopping might have limited me to what I always eat, other college students might buy healthier foods when they shop. Take a minute now and think about what you eat in an average day and see if you fall into the categories of eating unhealthy with the majority of college students. Next time you buy something to eat take a second and look whatââ¬â¢s in it and think to yourself. Should I be eating this? Or is there something healthier that I could be eating?

Imduction Processes Essay
Induction is the first step along a pathway of learning that a new worker undertakes when joining the social care sector or a new organisation and will continue all through their career. It is one of the principal most important processes within the organisation. Staff induction often focuses on the corporate policies, eg: safety, security, anti-discrimination, equality, etc. This is useful information, if not the most interesting to participants. Beyond policies, we also cover practicalities, for example how to carry out common administrative tasks such as completing weekly timesheets, changing address, how to fill out daily diary records for the service users. What information systems exist, we give out company email addresses and team leader/manager telephone numbers. Induction training is very important for new staff. Good induction training assists with retention of new starters ensuring they are settled in quickly into a productive happy role. This in turn is good for the company staff retention cuts recruitment costs. Induction training offers the opportunity to establish clear expectations from the outset in terms of integrity, ethics and professional social responsibility. The primary importance is to ensure that the individual is working within the guidelines of the law, companyââ¬â¢s policies, procedures and values, Safeguarding regulations and Care Quality Commission standards. It is then also extremely important for the service users, it enables staff to know and understand each individual and become familiar with their support plans to ensure that the staff follow a person centred approach to caring for the service usersââ¬â¢. The induction process we provide is based around the Skills for Care Common Induction Standards. These Common Induction Standards have been designed to provide a structured start for workers in the first 12 weeks of employment, which will help ensure that they are then safe to leave alone with responsibility for the people they support. When workers are expected to perform any tasks that are not covered by the standards, appropriate training will be sourced before the work is undertaken. There are eight standards that the induction covers, these are: Standard 1 Role of the health and social care worker Standard 2 Personal developments Standard 3 Communicate effectively Standard 4 Equality and Inclusion Standard 5 Principles for implementing duty of care Standard 6 Principles of safeguarding in health and social care Standard 7 Person-centred support Standard 8 Health and safety in an adult social care setting. Each standard contains a number of areas of knowledge that staff need to know about before they can work safely without close supervision. Each area is made up of outcomes which say what exactly you need to know about that area. Once the 12 week induction process is completed the staff will have knowledge of all the standards above and will have reached the desired outcomes of the induction. As a manager it is my responsibility to arrange for the new staff to learn about the different areas within the standards and that they gain enough knowledge to meet the outcomes for each area. People have different ways of learning, some learn by being told things through, others learn through watching, some through talking things and coming up with ideas and also some learn by actually doing the tasks. Prior to induction a training needs analysis is completed this will identify the best way to facilitate the training needs for each new member of staff. I will then liaise with our training department and arrange for the induction to take place. We will agree the best way to deliver the training to meet the individualââ¬â¢s needs. This can be done through classroom room based training sessions, reading and completing training booklets and also through shadowing an experienced member of staff who has the knowledge and skills to pass on. During the 12 week induction period the new member of staff will be assessed on their competency to ensure they have understood everything they have learned. These assessments will be carried out by the manager, team leader and/or training manager. Then when the staff member has successfully completed the induction period, the manager in combination with the team leader will sign off the Certificate of Successful Completion. Once completed staff areà encouraged to develop their job role to include new areas of work not covered by the common induction standards. The induction standards provide the basic training necessary for work in social care however as a company we provide further training for the additional tasks not covered through induction. This has been developed through skills for care learning sessions and the training available includes: Acquired Brain Injury ââ¬â (Introduction) Aspergerââ¬â¢s Syndrome ââ¬â (Introduction) Autism Syndrome ââ¬â (Introduction) Dementia and Confusion ââ¬â How to respond Dementia Defining Learning Disability ââ¬â (Introduction) Recognising and Managing Conflic Managing Medication Nutrition in Home Support Services Empowerment of Service User The completed induction links in to many of the knowledge requirements for the core units of the diploma in Health and Social Care qualification. Training is encouraged throughout employment to enable the staff member to develop new skills and knowledge and open up further career options. This supports and promotes professional development that will be beneficial to both the organisation and the staff member, ensuring that we are working in line with current best practice and guidelines. Effective induction can assist staff who want to move from one type of social care provision to another, or who are starting work with a different service user group, as they will have new things to learn so that they can understand how their practice may need to be adapted to the changed circumstances. The knowledge and skills training sessions can provide the learning necessary for workers to make a successful transition into a different part of the social care sector. Successful completion of induction ensures staff meet the General Social Care Council (GSCC) code of practice for social care workers, which describes the standards of professional conduct and practice required of social care workers as they go about their daily work. As an employerà AllCare has to adhere to a code of practice which includes their duty to establish a competent workforce. Ensuring staff successfully complete their induction is a part of this. The Common Induction Standards have been designed to help make sure that organisations can provide a quality service for the individualsââ¬â¢ we support, and that includes making sure new staff are safe to leave alone in the workplace to carry out their role and responsibilities. We centre on the mission that, our company will provide a safe environment for both staff and service users. We focus on safeguard and promote the welfare of the service users in our care, in compliance with Trafford multi-agency Safeguarding Adults Policy and Procedures and the publication of the ââ¬ËNo Secretsââ¬â¢ guidance by the Department of Health in 2000. This guidance stipulates that all local partner agencies should work together to prevent, detect and investigate concerns about possible adult abuse. The role of induction training with regard to safeguarding is to help develop and foster a shared understanding of the tasks, processes, principles, and roles and responsibilities outlined in national guidance and local arrangements for safeguarding vulnerable adults and promoting their welfare. Induction teaches how to recognise and act on signs of abuse and neglect, risk assessments and the making and management of referrals, ensuring that our staffs are competent and confident in carrying out their responsibilities for safeguarding and promoting service usersââ¬â¢ welfare. All staffs are provided with this information during induction via our employee handbook.

Should You Be Worried About Lead Pipes
Lead was commonly used to make pipes in plumbing for many centuries. It is cheap, rust resistant, and easy to weld. Eventually, health concerns encouraged a switch to alternate plumbing materials.à Copper and specialized plastics (like PVC and PEX) are now choice products for water pipes in homes.à à However, many older homes still have the original lead pipes installed. In the United States and Canada, homes built before the 1950s should be suspected of having lead pipes, unless they have been replaced already. Lead soldering, applied to join together copper pipes, continued to be used well into the 1980s.à Lead Is a Serious Health Concernà We absorb lead through theà air, our food, and the water we drink. The effects of lead on our body are very serious. The consequences of lead poisoning range from kidney damage to reproductive problems including declined fertility. Lead poisoning is especially worrisome in children, as it affects the development of their nervous system and causes permanent changes in behavior and in the ability to learn. In the last few decades, we generally have been well educated about the problem of lead in old paint and about what we needed to do to prevent children from being exposed. The issue of lead in the water, however, recently only became a public topic of conversation in the wake of the Flint lead crisis, wherein, in an ââ¬â¹egregious case of environmental injustice, an entire community was exposed to lead-tainted municipal water for far too long. It Is Also About the Waterà Old lead pipes are not automatically a health threat. A layer of oxidized metal forms on the pipe surface over time, preventing water from directly contacting the raw lead. By controlling the pH of the water at the water treatment plant, municipalities can prevent corrosion of this oxidized layer, and even add certain chemicals to facilitate the formation of a protective coating (a form of scale). When the water chemistry is not properly adjusted, as the case was in Flint, lead is leached out of the pipes and can reach consumersââ¬â¢ homes at dangerous levels. Do you get your water from a well instead of a municipal water treatment plant? If you have lead in your house pipes, there is no guarantee that the water chemistry is not at risk of leaching lead and bringing it to your faucet. What Can You Do? If you have concerns about your pipes, run water from your tap to flush out your pipe before you drink it, especially in the morning. Water that has been sitting around for several hours in your house pipes is more likely to pick up lead.à Water filters can remove most lead from your drinking water. However, the filter has to be specifically designed for lead removal ââ¬â check whether it is certified for that purpose by an independent organization (for example, by the NSF).à à Hot water is also more likely to dissolve lead and carry it to your faucet. Do not use hot water directly from the faucet to cook or make hot drinks.à Have your water testedà for lead. ââ¬â¹While your municipality may have changed all of its delivery conduits to non-lead materials, the pipes inside your older home (or connecting to the municipal system under your front lawn) may not have been replaced. To confirm your water is safe to drink, contact a reputable, certified water testing lab and have them do an analysis. It is more costly, but its better to choose an independent company that will not try to sell you a treatment system.Your childââ¬â¢s blood level can also easily be tested for lead by a pediatrician. Detecting an elevated lead blood level early is important and would give you time to determine where itââ¬â¢s coming from.Children spend a lot of time in school ââ¬â howââ¬â¢s the water there? Request water quality tests from your school district. If they do not have them done periodically, require they do so. Hunters are leaving lead out of their bullets, and ââ¬â¹Ã¢â¬â¹anglers are encouraged to choose alternatives. Getting lead also out of our homes and our drinking water will take more work, but it is important.

Effects Of Anorexia Nervosa On Body Weight And Shape
Self-Analysis Paper Item #1: As a nineteen-year old female college student, it is not a huge surprise that I would develop an eating disorder at one point in my adolescent years. Specifically, I have been diagnosed with anorexia nervosa. With anorexia nervosa, I view myself as overweight despite the fact that I am considered underweight for my particular age and height. I have developed an intense fear of gaining weight and as a result, I diet and exercise excessively. This fear causes me to be obsessed with the thought of food consumption, leading me to abstain from eating too much and possibly gaining unwanted weight in hopes to achieve the ideal body image that I believe I need in order to be accepted. Having a distorted bodyâ⬠¦show more contentâ⬠¦In addition to barely eating anything throughout the day, I participate in extreme exercises to burn a significant amount of calories and fat. Dieting and exercising has successfully assisted in my desired weight loss in a short period of time . Item #3: My attempt to achieve my desired body image came with many consequences, psychological and physical. A major psychological sign of my anorexia nervosa is that my self worth has been defined by the way I think I look: overweight. Due to this distorted body image I am consumed with perfecting, I am constantly preoccupied with the thought of food and how to continue losing more weight to accomplish my goal of becoming thin. Emotionally, I have developed strong feelings of anxiety and irritableness when it is the normal time to eat a meal. I have also become incredibly sensitive to comments regarding food, weight, body shape, and exercise. Restricting my food intake has helped me relieve these negative emotions by having a sense of control over my body, even though I am still left dissatisfied with what I see of myself. Item #4: Despite the fact that I feel better about myself when I lose weight, it does not necessarily make me look better. Since I pushed myself for an extended time to eat extremely small portions of food or sometimes nothing at all, my body has become noticeably

Persuasive Essay On Dress Code - 733 Words
When moving from California to Texas, I was fortunate enough to still be in a great public school system, but I was not lucky enough to escape an excessively strict dress code. While many people in private schools have complete uniforms to implement equality, being confined through a severe dresscode not only impaired my freedom of expression, but also the ability to grow into myself. As an adult, I am expected to make choices for myself, present myself in a certain way, and how important I am depends on how unique I am. Spending some of the most impressionable years of my life in a high school priding itself in a firm dress code, I feel as though it held me back from the experience I needed to be a confident adult. Now that Iââ¬â¢m inâ⬠¦show more contentâ⬠¦As young adults, teenagers are also expected to begin taking on responsibilities and are given the freedom to choose things for themselves, yet such a strict dress code inhibits the ability to make the most basic c hoice of dressing yourself. No one dresses the same every day because no one feels the same everyday. Dressing yourself allows you to express your mood and interests. It is a way to find what style makes you feel most confident, which is something you can carry throughout the rest of your life. It allows you to form connections with others and figure out which people have the same interests as you. Being a teenager is about finding yourself and through dress, you meet friends, build confidence, and express your interests. This in mind, I think freedom is the ability to express yourself as long as it is within the realms of the law. Humans are unique in the way that we are all significantly different, and our differences is what create medicines, buildings, books, and so much more. We are raised to believe that we are all special, because we are. No one is a copy of someone else.

Investigations on Combustion and Emission â⬠Free Samples to Students
Question: Discuss about the Investigations on Combustion and Emission. Answer: Introduction Biodiesel is an alternative to fuel which can be considered similar to the conventional or fossil diesel. It is produced directly from vegetable oil, animal fats, tallow and the waste of cooking oil. The method by which these products are used for transforming into the form of biodiesel is known as transesterification. The major sources of oil are the rapeseed, palm and soybean. Most of the biodiesel produced in UK comes from the rapeseed. But the contemporary production of biodiesel is sourced from the wasted vegetable oils of restaurants, chip shops, industrial food producers and so on (Gui, Lee and Bhatia 2008). As the raw oil is very costly therefore the oil directly from the agricultural industry is not produced for the commercial purpose even though it can be considered as the greatest possible source. The final cost of the oil after the addition of transforming it to biodiesel is a lot as compared to fossil fuel Although waste vegetable oil can be available for free or at a ve ry cheap rate but it needs to purified before converting to biodiesel. The fact is that the biodiesel that is produced from the waste of vegetable oil has the ability to compete with fossil diesel. This assignment will look into the benefits of biodiesel and the different factors that play an important role in its production. Biodiesel is an environmental friendly product which has many beneficial properties. One of the important benefits of biodiesel is that it can be considered carbon neutral. The specific term refers to the fact there is no net output of carbon from this fuel in the form of carbon dioxide. The reason behind this effect is that same amount of carbon dioxide is absorbed as well as released in the process of growing of the crop and the combustion of the fuel (Balat 2011). Moreover, the carbon dioxide is released in the production of the fertilizer which is necessary to fertilize the agricultural field in which the oil crops are cultivated. Biodiesel is a biodegradable product which is totally non- toxic that is, spillage of the fuel pose a minimum amount of risk as compared to the spilling of fossil diesel. It also has a higher flashpoint as compared to fossil diesel and therefore safe and secured in the course of crash (Atabani et al. 2013). In the production of biodiesel, the process of transesterification is used which is also known as alcoholysis. It involves the displacement of alcohol from an ester by another alcohol in a process which is similar to the method of hydrolysis with a slight difference of using water in the other. Non- edible plant oils are also used for crude oil production of biodiesel. When the use of non- edible oils are compared to edible oils, it is found to be significant as well as costly but there is availability at large. The production of biodiesel from the non- edible oilseed crops includes jatropha, karanja, tobacco and so on (Churchill and Srinivasan 2017). The production of biodiesel from the waste cooking oil into the partial alternative of petroleum diesel is a probable option for solving the issues of energy crisis as well as environmental pollution. The edible vegetable oil fuels were not taken into consideration because of their cost which was higher compared to petroleum fuels. The reaction between oil or fat and alcohol is a process of reversible reaction therefore it must be added in surplus for driving the reaction in the appropriate direction to enable complete conversion (Collet et al. 2014). With the success of the transesterification process, the separation of the ester and glycerol layers are signified after the time of reaction. The production of biodiesel is a complex process which involves the mixing of alcohol and catalyst followed by the separation and removal of alcohol. Then the process of glycerin neutralization takes place followed by methyl ester wash. It must be assured that the finished biodiesel is analyzed by means of sophisticated analytical equipment so that the necessary specifications are met with (Issariyakul and Dalai 2014). To list the most crucial factors in the production of biodiesel are- complete reaction, removal of glycerin, catalyst and alcohol and absence of free fatty acids. Impact of biodiesel Due to the instability in the political condition of the Organization of Petroleum Exporting Countries or OPEC the price of fossil fuels ate soaring high. Again the countries with comparatively lesser production of fuel or without fossil fuel production would be profitable from the utilization of the previous land resources used for the cultivation of bio- fuel crops. This is the reason behind the increase in production of bio- fuel each year and there is an assumption that in the upcoming days, biodiesel is going to be the main bio- fuel all over the world. The graph of biodiesel production has not fallen down since 1991 (Lee et al. 2014). While studying the impact of biodiesel in the world, it was found out that the space available in the UK for producing the biodiesel crops is not enough according to the target set for meeting the renewable energy production in UK. Also, the demand for water is much more in the bio- fuel crops as compared to the traditional crops. The second gener ation bio- fuels also pose certain benefits such as improving the soil quality, carbon requisition in soil and soil erosion (Murugesan et al. 2009). It was also found out that as the bio- fuel industry has expanded, the price of foods has increased and there is shortage of land available for the cultivation of food- based crops in most of the countries of Asia, Africa and Latin America (Rawat et al. 2013). It is a non- toxic fuel which degrades at a speed four- times faster than diesel whereas pure bio diesel degrades around 85%- 88% in water. One of the most important advantages of using biodiesel is that when it I mixed with diesel fuel, the efficiency of engine is increased. The storage becomes safe due to the higher flashpoint in bio diesel. Being an oxygenated fuel, it is implied that the oxygen content plays an important role in making the fatty compounds fit for diesel fuel by burning the cleaner. Ames mutageniety tests have found out that it is responsible for reducing the risk of cancer by 90%, thus providing a domestic and renewable supply of energy (Murugesan et al. 2009). The list of benefits of biodiesel also includes the non- production of greenhouse effects as the amount of carbon dioxide released in the production process equals the amount of carbon dioxide used in the plants. It can also be used directly in the compression of ignition engines without any kind of consid erable adjustment in the engine. It does not contain sulphur and the features are relatable to the future policies of Europe which will put restriction on the use of sulphur (Singhasuwan et al. 2015). The chemical characteristics of bio diesel showed that there are lower levels of poisonous and reactive hydrocarbon species when the bio diesel fuels were used. Along with all these advantages, the bio diesel is not free of disadvantages which are listed below. There are only few disadvantages of biodiesel as compared to its advantages. The use of bio diesel has resulted in a bit of decrease in the fuel economy on the energy basics. As its density is more than diesel fuel in the cold weather therefore there might be a need to use the blends in the sub- freezing conditions. With the decrease in production of vegetable oil it has become more expensive (Talebian-Kiakalaieh, Amin and Mazaheri 2013). Bio diesel market development The market of bio diesel is one of the fastest growing in the chemical industry. The production of bio diesel is the highest in the European Union where the rate is higher than ethanol but the production of both these fuels are comparatively smaller than that of Brazil and the United States. There are two factors that have made EU the leader in the production of bio diesel. One factor being the amendment in the Common Agricultural Policy which is a supranational and locally oriented policy of the farm for the member of European Union countries. the other factor being the high tax of the fuel which have led to the indirect subsidy of the production of bio fuel either through full or partial exclusion from the fuel excise tax. In the EU member countries tax generally comprise 50% or more than the selling price of diesel (Unosson et al. 2014). EU is the global leader in the production and consumption of bio diesel with a figure of 4.98 million tones with an increase of 1.8 million in one year. Bio diesel was accountable for around 80% of the bio fuel production in the EU countries. The EU still continues to be the leader in the market of bio diesel production and will continue to do so, followed by US and Brazil. Other countries in the run for bio diesel production include Netherlands, China, India, Thailand and New Zealand. In todays world biodiesel has to overcome a lot of challenges for becoming the mainstream energy source. The challenges might be the cost of feedstock, availability of feedstock, quality of fuel or the changing norms of International Compatibility of Bio diesel Testing Standards. Such issues are not to be solved in a short span of time which reflects that the road to achieve biodiesel as the main source of energy is not going to be smooth. It might take a minimum of 5- 10 years for the change to take place. Bio fuels do not only face technical challenges but also come across social, economic and environmental challenges ((Rawat et al. 2013). A combination of the price hike, shortage of supply and issues related to global climate change are urging the development of alternative ways apart from the burning of fossil fuels so that the transportation energy requirements could be met. The best option in this regard can be considered as the use of liquid fuels that is derived from the cellulosic biomass. These new bio fuels have the ability of clean burning, carbon- neutral and also renewable. The main focus is on the technological challenges to produce superior quality of bio fuels in such a way that can win over sustainability and have economically competitive advantage over gasoline. The other challenges include the restraint that is posed by market and economics, limitations of resources, risks related to health, climate forcing, demand of water and land use. To cope up with these challenges there is a requirement of efficient life- cycle perspective. There is a need to understand the farmers, feedstock options and predict bio fuel production technologies and practices for evaluating the transitions and confront with uncertainty (Singhasuwan et al. 2015). Conclusion Therefore it can be concluded from this assignment that biodiesel is a renewable fuel that can be used in place of the diesel fuel manufactured from petroleum. The major sources of biodiesel include rapeseed oil, sunflower oil and palm oil. The process of bio diesel production is a complex one involving a number of stages. They are used in regular diesel engines without any kind of changes in the engine. It can be stored as well as transported with the use of diesel fuel tanks and other equipments. This renewable and clean burning diesel replacement has decreased the dependence on foreign petroleum to a great deal. The components of production include a diverse mix of feed stocks which include recycled cooking oil, soya oil and animal fats. Bio diesel is the first and only EPA- designated advanced bio fuel in the commercial sector of the production process across the country and also the pioneer in reaching the production level of one billion gallon. Thus, it can be recommended that it can be used in the diesel engines without any change and abiding by the stern technical fuel quality and the specifications of engine performance.
