Top French Pronunciation Mistakes and Difficulties

Many students find that pronunciation is the hardest part of learning French. The new sounds, the silent letters, the liaisons — they all combine to make speaking French very tricky. If you really want to perfect your French pronunciation, your best option is to work with a native French speaker, preferably one who specializes in accent training. If that isnt possible, then you need to take things into your own hands by listening to French as much as possible, and by studying and practicing the pronunciation aspects that you find most difficult. Here is a list of the top French pronunciation difficulties and mistakes, with links to detailed lessons and sound files. The French R The French R has been the bane of French students since time immemorial. OK, maybe its not quite that bad, but the French R is pretty tricky for a lot of French students. The good news is that it is possible for a non-native speaker to learn how to pronounce it. Really. If you follow my step-by-step instructions and practice a lot, youll get it. The French U The French U is another tricky sound, at least for English speakers, for two reasons: its hard to say and its sometimes difficult for untrained ears to distinguish it from the French OU. But with practice, you can definitely learn how to hear and say it. Nasal Vowels Nasal vowels are the ones that make it sound like the speakers nose is stuffed up. In fact, nasal vowel sounds are created by pushing air through the nose and mouth, rather than just the mouth as you do for regular vowels. Its not so difficult once you get the hang of it — listen, practice, and you will learn. Accents French accents do more than just make words look foreign — they modify pronunciation and meaning too. Therefore, its extremely important to know which accents do what, as well as how to type them. You dont even need to buy a French keyboard — accents can be typed on virtually any computer. Silent Letters Many French letters are silent, and a lot of them are found at the end of words. However, not all final letters are silent. Confused? Read over these lessons to get a general idea of which letters are silent in French. H  Muet  / Aspirà © Whether its an  H  muet  or an  H aspirà ©, the French H is always silent, yet it has a strange ability to act as a consonant or like a vowel. That is, the  H aspirà ©, although silent, acts like a consonant and does not allow contractions or liaisons to occur in front of it. But the  H  muet  acts like a vowel, so contractions and liaisons are required in front of it. Confusing? Just take the time to memorize the type of H for the most common words, and youre all set. Liaisons and Enchaà ®nement French words flow one into the next thanks to liaisons and enchaà ®nement. This causes problems not only in  speaking but in  listening comprehension  as well. The more you know about liaisons and enchaà ®nement, the better youll be able to speak and understand whats being spoken. Contractions In French, contractions are required. Whenever a short word like  je, me, le, la, or  ne  is followed by a word that begins with a vowel or H  muet, the short word drops the final vowel, adds an apostrophe, and attaches itself to the following word. This is not optional, as it is in English — French contractions are required. Thus, you should never say je  aime or le  ami — it is always  jaime  and  lami. Contractions  never  occur in front of a French consonant (except H  muet). Euphony It may seem odd that French has specific rules about ways to say things so that they sound prettier, but thats the way it is. Familiarize yourself with the various euphonic techniques so that your French sounds pretty too. Rhythm Ever heard anyone say that French is very musical? Thats partly because there are no stress marks on French words: all syllables are pronounced at the same intensity (volume). Instead of stressed syllables or words, French has rhythmic groups of related words within each sentence. Its kind of complicated, but if you read my lesson youll get an idea of what you need to work on.

Analysis Of The Book Lament For A Son - 929 Words

Stages of Grief Introduction The book, Lament For a Son, written by Nicholas Wolterstorff talks about his pain and grief after losing his 25-year-old son (Joy, 2009). His son died while on a mountain-climbing expedition. Dr. Wolterstorff has several books published during his career as a philosophical theology professor in Yale Divinity. However, he wrote Lament for a Son with a different journal style since it is a personal thing for him. The book is similar to a journal as he narrates the events that happened before and after his son’s death. The emotions expressed in the book are common among people who lose close relatives. What matters is how a person handles the issue. Kubler-Ross invented the five stages of grief; denial, anger, bargaining, depression and acceptancethat explain the escalation of grief when stricken by bad news (Axelrod, 2004). The paper looks into the book and its relation to the five stages of grief. Question 1 As demonstrated by the five stages of grief, Dr. Wolterstorff suffers greatly emotionally as he deals with his son’s death. In a bid to settle his depression, he reads the Bible on similar experiences that people had (Wolterstorff, 1987). He finds hope after reading and comprehending about Jesus Christ life, death, and resurrection. The story gives him hope that one day his son, Eric, will resurrect one day because God has the power to make such things possible. Dr. Wolterstorfffinally accepts the fact that Eric died, but he will see him inShow MoreRelatedAnalysis Of Lament For A Son And How The Author Of The Book ( Wolterstorff ) Found Joy After His Essay1263 Words   |  6 Pagesbad break up, losing a job, or losing a loved one.

Marketing Research And Communication Samples †MyAssignmenthelp.com

Question: Discuss about the Marketing Research And Communication. Answer: Objectives of the research Market research is one of the most important aspect ofmarketing as it gives out an in depth idea and insightful information about the target market, competition and the expansion scope along with the growth of the business as well as the industry. Market research facilitates, the strategy and planning procedure organizes the policy and decision making of the business organization. Market research is essential in every step that a company takes whether it is a large scale operation or a small scale business, without having relevant information about the business environments it is impossible for an organisation to take any decision (Sarstedt and Mooi 2014). The objective of market research is basically to get an insight about customers and target market of the business. Customer satisfaction is one of the most significant ideas behind creating andmarketing products. Market research helps in finding out the strengths and opportunities of the business by reviewing and analysing data. The company also can understand where there is a gap in what the customer wants and what is being provided by the company. The weaknesses of the product or service are also brought into the light with the help of market survey. Some of the key objectives of customer satisfaction market survey are: To understand the market segmentation To identify the growth while diversifying the product To get an in-depth review about the level of customer satisfaction and prospects of improvement To identify the gap of performance by the company on the existing products. Fulfilment of objectives In order to fulfil the objectives of the market research it is important for a large scale business organization to team up with a research company who will do the needful as per the requirements of the business. The management of the company should keep a check on the research process in order to try to ensure that the research is performed in an effective and professional way and that the data collected and analyzed by the third party is consistent. The company needs to have an information base data collection of the existing customers who can give insights regarding the weakness and the requirement gap that has occurred in the product or service. The regular customers will also be able to answer the fact that whether a diversification of the product will be accepted by the people or what are the prospects of improvement. As Aldi is a supermarket chain and has ingrown brand as well, the company places itself in the market as a high quality and reasonable price product and service. Aldi is a multinational company that has a huge turn over. Research should take place depending on the market segmentation (Babin and Zikmund 2015). Research takes place in two basic ways one is secondary and the other is primary. Under these categories there are other sub categories. Secondary research forms the fundaments of the primary research it is the information that is gathered and analyzed form the documents and journals that are already available in the particular subject or topic. Reviewing and understanding this data saves time and a lot of effort it also makes the primary research process a lot easier. For a super market brand like Aldi there are several documents that are already available. Any research process requires a plan and a strategy to proceed (Szolnoki and Hoffmann 2013). To understand the customer satisfaction of Aldi what is first required is to find out which outlets have the maximum number of footfall and gather information about the customers from those outlets and stores (McQuarrie 2015). As Aldi is a multinational company it is important for the research company to understand that the buying behavio ur of a person heavily depends on the cultural background of that person. If a questionnaire is being prepared to be circulated among the existing customers for the purpose of primary research there are several points to be kept in mind. Firstly, the company should make the questions compact and to the point. Secondly, the questions should be relevant to the location it is catering. Thirdly, the language of the questions should be grammatically correct and should be in easy language for everyone to understand (Yin 2013). Fourthly, there should not be many questions as it has the potential to take away interest from the customers. One of the biggest aspects of market research is gathering of sample, therefore it is important for the company to have a clear idea about the specific topic that has to be research. Gap analysis is a large topic; the company should narrow down the idea to a single path so that the focus is not all over the place. If the central idea is set, the sampling wi ll also be easy and more accurate resulting in a better analysis and review of data collected from this sample. Stores should have a list of loyal customers and a record of how frequently these people visit the stores, to identify the loyal customers the research company can go through the records of billing (Amphora, Birks and Wills 2013). Conclusion In order to analyze the gap in between what Aldi is offering and what is expected by the customers there can be several option for the company. Firstly the managers of the stores can be appointed to gather information from the customers as feedback. Feedback forms can be gathered ad analyzed by the research company. Customers can be emailed questioner for the improvement of the services and the products that Aldi has to offer. There should be an account in which managers of different stores record the cases of grievances and complaints that has been escalated by the customers, that account is very insightful and will give out a lot of in depth knowledge about the satisfaction level of the company along with the gap that has been created on the behalf of the business. A manager who is responsible to carry out an research process should have a clear mind as a pre-determined idea about the outcome can hinder the analysis process making it biased.

Applying Ethical Theory Apple and FBI

Question: Discuss about the Applying Ethical Theory for Apple and FBI. Answer: Introduction Apple Vs FBI: All you Need to Know This case study enlightens the disputes and arguments between Apple and FBI showcases various advantages and disadvantages of the high security provided in the Apples iPhones. The case study focuses on the negative aspects of the security and authorization promoted in the iPhones while the Apple defends the situation by claiming that the security and authorization are for the safety and privacy of the users data which cannot be compromised at any cost. The huge concern in this case study is the rising disputes and disagreements between the technical or IT companies and the government firms. There are several clashed between them due to the data access rights and authorization processes. In this case study, the US FBI identifies a criminal and also investigates that the criminal used the iPhone (Litschka et al, 2011). The FBI also claims that more information about the criminal and his companions can be extracted by using the iPhone as a key element. This phone requires passwords for the phone lock which the FBI requested iPhone to unlock (Haidt Jonathan, 2012). Apple however responded claiming that providing the key or solution to the locks and granting the access and authorization without the passwords would require software and would be completely unsafe. The company defended their decision by claiming that if the such kind of unlocking key or solutions would be developed then the significance of the locks would not remaining powerful anymore. Ethical Issues, Cyber Crime and Security The ethical issue here is the safety and security provided by the company. It has been stated that the government agency FBI wanted to use the unlocking software or key which request was avoided by Apple. The company needs such high end security providing devices which cannot be tempered by anyone and the security must be so strong for anybody to unlock it easily for solving this issue. The FBI found another solution of getting the phone unlocked by some another agent or company. It was for governmental use where the government agency hired another agency to unlock the system of the iPhone (Bergum Dossetor, 2005). This was an ethical step taken by the FBI to get the correct details of the shooter. The company did focus on securing and maintaining the privacy of the users data. The security features of Apple are quite stronger but are yet broken and tempered by another company (Ravven Heidi, 2013). As per Apple, (2016) the ratio of cyber crime has increased as the security and privacy gets enhanced. The safety and security provides a shield to the criminals under the influence of which, the criminals are able to commit various cybercrime. However for the governmental bodies, these security aspects must be compromised. Social inclusion describes the inclusion of the society which results in the positive changes and actions that are taken positively by the company, this case study reveals that the results may be positive in fact there are some action steps that may be a beneficiary for FBI. In the given case study, there are community and identity as the topics which consists of the common interests of the company as such there are common standards, norms and values carried out by the company to positively plan for the increase in the awareness of cyber crime (Ravven Heidi, 2013). As discussed, privacy and security are important for cyber crime, so are these concepts important. Pervasive computing are the wireless technologies with advanced form but are sometimes dangerous as they seem to be the privacy advocate which is concerned with a practical standpoint. At the end these ethical issues are considered and the results are considered that Apple stuck on the success with defending civil liberties (Ung Hee, 2013). The consequentialism and deontological Theories and their implications on the case study In this case the consequentialism theory can be applied to identify the exact need and importance of the demand made by the governmental bodies. This theory helps in identifying the right thing to do as per the consequences. If the condition is extreme where the company can get a solution to a huge problem just with the cooperation of the IT firm, then both the parties must mutually understand the requirements and propose a solution. IN this case too, the court identified a solution according to the situation (Pojman Fieser, 2009). Apple was not ready to compromise with its security and safety aspects while the FBI was demanding the company to unlock several features and provide solution to get access to the phone which gets the consequentialism theory into action. In this case none of the side was ready to compromise thus the court decided to find a third party which can help in unlocking the phone and extracting the data. This mission and idea was successful and the solution was obtained. The consequentialism theory thus states that identification of the correct action to perform is very important and necessary.This theory helps immensely in identifying the proper and required solution and to get the beneficial outcomes from the solutions (Ravven Heidi, 2013). The deontology theory states that to break a promise given to the other person is seen as a lack of respect and is completely a wrong practice (Pojman Fieser, 2009). In this case, applying the deontoligical theory for Apple, the company believes that it has promised its customers for providing security and safety for their data and breaking the promise made to the customers while providing decoding and unlocking solutions to the FBI would break the trust of the customers and is ideally wrong practice to follow in the market. Thus the company decided to stand by the decision of keeping the promise made to the customers of securing their data and not providing the FBI with the decoding solutions (Bergum Dossetor, 2005). The significance of the deontological theory here is to identify the promises made ot the customers and maintain the trust of the customers by following the promises made.This theory would help into getting a trustworthy base and a reliable reputation and gives a solution which is highly beneficial. Recommendations It has been witnessed that after identifying the different theories and applying it on the case study, the problems can be solved by applying the feasible and proposed solutions which are documented in the theories. The ethical theories like deontological and consequential theories, provides guidance regarding the action to be taken when an adverse situation arises. The in depth analysis of the problem and the identification of correct solution and methodology is provided by these theories which would help in getting an effective and efficient result. https://www.cnbc.com/2016/03/29/apple-vs-fbi-all-you-need-to-know.html References: Apple (2016).

Aqua Silencer free essay sample

This project is an attempt to reduce the toxic content of diesel exhaust, before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres, such as refineries, chemicals processing industries, open cost mines and other confined areas, which demands the need for diesel power packs. WORKING PRINCIPLE The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas using perforated tube. By using perforated tube the back Pressure. Will remain constant and the sound level is reduced. Using the perforated tube the fuel consumption remains same as conventional system. By using water as a medium the sound can be lowered and also by using activated charcoal in water. We can control the exhaust emission to a grater level. The water contamination is found to be negligible in aqua silencer, because the amount of acidity level in aqua silencer is expected to be below the dangerous acidity. We will write a custom essay sample on Aqua Silencer or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is smokeless and pollution free emission and also very cheap. The aqua silencer’s performance is almost equivalent to the conventional silencer. ADVANTAGES Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries. Considering the available fuel resources and the present technological development, Diesel fuel is evidently indispensable In general, the consumption of fuel is an index for finding out the economic strength of any country. Aqua silencer free essay sample An aqua silencer is used to control the noise and emission in ic engines. The reason why we go for aqua silencer is, in today life the air pollution causes physical ill effects to the human beings and also the environment. The main contribution of the air pollution is automobiles releasing the gases like carbon dioxide, unburned hydrocarbons etc. In order to avoid this type of gases by introducing this aqua silencer. It is fitted to the exhaust pipe of the engine, Sound produced under water is less hearable than it produced in atmosphere. This mainly because of small sprockets in water molecules, which lowers its amplitude thus, lowers the sound level. The emission can be controlled by using the activated charcoal layer and it is highly porous and posses extra free valences so it has high absorption capacity. So absorb the gases from the engine and release much less position to the environment. We will write a custom essay sample on Aqua silencer or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The noise and smoke level is considerable less than the conventional silencer, no need of catalytic converter and easy to install. CHAPTER 2 COMPONENTS AND EXPALANATION: COMPONENTS: Perforated Tube. Charcoal Layer. Outer Shell. Non Return Valve. Flange. H-Nipple. EXPLANATION: PERORATED TUBE The perforated tube consists of number of holes of different diameters. It is used to convert high mass bubbles to low mass bubbles. The charcoal layer is pasted over the perforated tube. Fig 1. Perforated Tube CHARCOAL LAYER The charcoal layer has more absorbing capacity because it has more surface area. This charcoal is called as ACTIVATED CHARCOAL. It is produced by heating the charcoal above 1500 ‘c foe several hours in a burner. Its surface area gets increased. Fig 2. Charcoal Layer Outer Shell: The whole setup was kept inside the outer shell. It is made up of iron or steel. The water inlet, outlet and exhaust tube was provided in the shell itself. Fig 3. Outer Shell NON RETURN VALVE: The non return valve is a mechanical device a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure. The Aqua silencer was filled with water and it is directly connected to the exhaust pipe of the engine. There is a chance for the water to get enter into the engine cylinder. To avoid this, Non return valve is used. It allows the flow of fluid in one direction only. Fig 4. Non Return Valve FLANGE: A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Here flange is used to connect the silencer to the engine. Fig 5. Flange H- NIPPLE: It is a device which is used to connect two pipes together. It consists of two threaded sides. Fig 6. H-Nipple CHAPTER 3 CONSTRUCTION: Basically an aqua silencer consists of a perforated tube which is installed at the end of the exhaust pipe. The perforated tube may have holes of different diameters. The very purpose of providing different diameter hole is to break up gas mass to form smaller gas bubbles the perforated tube of different diameter . Generally 4 sets of holes are drilled on the perforated tube. The other end of the perforated tube is closed by plug. Around the circumference of the perforated tube a layer of activated charcoal is provided and further a metallic mesh covers it. The whole unit is then placed in a water container. A small opening is provided at the Top of the container to remove the exhaust gases and a drain plug is provided at the bottom of the container for periodically cleaning of the container. Also a filler plug is mounted at the top of the container. At the inlet of the exhaust pipe a non-return valve is provided which prevents the back flow of gases and water as well. Fig 7. Aqua Silencer CHAPTER 4 WORKING: As the exhaust gases enter in to the aqua silencer, the perforated tube converts high mass bubbles in lo low mass bubbles after that they passes through charcoal layer which again purify the gases. It is highly porous and posses extra free valences so it has high absorption capacity. After passing over the charcoal layer some of the gases may dissolved in to the water and finally the. Exhaust gases escape through the opening in to the atmosphere. Hence aqua silencer reduces noise and pollution. CHAPTER 5 EFFECTS OF DISSOLVED GASES ON WATER: The water is a good absorbing medium. In aqua silencer the gases are made to be dissolved in water. When these gases dissolved in water they form acids, carbonates, bicarbonates etc, Action of dissolved SO2 : When Sox is mixed in water, it form SO2, SO3, SO4, H2SO4, H2SO, i. e. sulfur Acid ( H2SO3,), it forms Hydrogen Sulphide which causes fol rotten egg smell, acidify and corrosion of metals. Action of dissolved CO2: The dissolved carbon dioxide forms bicarbonate at lower PH and Carbonates at higher PH. This levels 40-400 mg/liter. The form a scale in pipes and boilers. The carbon dioxide mixes with water to form Carbonic acid. It is corrosive to metals and causes green house effect. Effect of dissolved NOx: The Nitrogen in water under goes Oxidation to form ammonia, Nitrate, Nitrite, Nitric acid. This synthesis of protein and amino acids is effected by Nitrogen. Nitrate usually occurs in trace quantities in surface water. A limit of 10 mg per liters Nitrate is affordable in drinking water. CHAPTER 6 METHODS TO CONTROL THE WATER POLLUTION: In aqua silencer the water gets polluted by the dissolved gases As in above topics said these gases are mixed with water to form carbonate, acids like carbonic acid, sulfuric acid, and Nitrous acid etc. the petroleum products contains phenols which gives suffocating smell. The sulfur gas mixes with water to form hydrogen sulfide, which give rotten egg smell. These should be controlled to minimum the water pollution. There are two methods: 1) Lime water wash method 2) Adsorption process LIME WATER WASH METHOD: The water is treated with the calculated quantities of slaked lime. One should have the quantitative analysis of water to go for this process. After mixing the heavy precipitates settle down as sludge at the bottom of the tank are removed from time to time. Lime can neutralize any acid present in the water. SO2, gases are removed from the flue gases forming calcium sulphate. The precipitates dissolved carbon dioxide as calcium carbonate and converts bicarbonate ions into carbonates. The equations are given below. The SO2 gas is removed from the flue gases forming calcium sulphate Ca(OH)2 + SO2. .. .. .. . CaSO3 +H2O Neutralizes any acid present in water 2HCL + Ca(OH)2. CaCl2 + 2H2O H2SO4 + Ca (OH)2.. CaSO4 + 2H2O Precipitates bicarbonate as calcium carbonate CO2 + Ca(OH)2.. CaCO3+2H2O Precipitates bicarbonate as calcium carbonate Ca(HCO3)2 + 2Ca (OH)2 2CaCO3 + 2H2O Converts bicarbonate ions (Like NaHCO3, KHCO3 etc. ) into carbonates. NaHCO3+ Ca(OH)2 CaCO3 + H2O + Na2 CO3 LIMITATIONS OF LIME WATER WASH METHOD: 1. Amount of neutralization capacity is limited 2. It is very difficult to handle 3. Bridging and form are formed 4. It is expansive 5. Regeneration is possible 6. Lime in any form it is difficult to handling. ADSORPTION PROCESS: Activated charcoal is available in granular or powdered form. As it is highly porous and Possess free valences. So it posses high absorption capacity. Activated carbon is more widely used for the removal of taste and odorous from the public water supplies because it has excellent properties of attracting gases, finely divided solid particles and phenol type impurities, The activated carbon, usually in the powdered form is added to the water either before or after the coagulation with sedimentation. But it is always added before filtration. Feeding devices are similar to those used in feeding the coagulants. ADVANTAGES OF ADSORPTION PROCESS: 1. It increases the coagulation power of the process. 2. Its use reduces the chlorine demand. 3. The excessive dose of activated carbon is not harmful. 4. The treatment process is very simple and it requires nearly no skill 5. The efficiency of removing color, odor and taste is quite high. 6. It has excellent properties of attracting gases. CHAPTER 7 MERITS AND DEMERITS OF AQUA SILENCER MERITS: No vibration when the engine is running. Start the engine easy. Control emission and noise in greater level. Carbon is precipitated. DEMERITS: Frequent water filling is required. Silencer weight is more comparing to conventional silencer. Cost of activated charcoal is more. CHAPTER 8 SCOPE OF THE PROJECT: There has been an increasing concern in recent years over the increasing of transportation and discharge of industrial waste waters into environment. The automobile emission contains air pollutants and other species. Almost all pollutants are toxic in nature. Some of the examples are CO, CO2, NOX, and Hydrocarbon. Among the air pollutants, all are most effective pollutants. Hence, the removal of pollutants was selected for the present study. Several expensive techniques are available in developed countries. But in developing countries like India is not applicable since adsorption technique is less expensive and economically feasible, it has been selected for the present study using some cheap cost chemicals as an effective adsorbent. Therefore the objective of the present work was to test the ability of some chemicals in removing air pollutants from automobile emission. CHAPTER 9 RESULT ANALYSIS ON EMISSION: Fig 8. Result Analysis of Noise without Aqua Silencer Fig 9. An employed Aqua Silencer Fig 10. Analysis with Aqua Silencer RESULT ANALYSIS ON NOISE: First the noise of the engine with 4-stroke single cylinder diesel engine in our laboratory was up to 105db. Then the noise produced after the aqua silencer was fitted up to 75db. Thus the noise reduction was achieved and the noise was measured by using decibel meter. CHAPTER 10 CONCLUSION: The aqua silencer is more effective in the reduction of emission gases from the engine exhaust using perforated tube and charcoal, by using perforated tube the backpressure will remain constant and the sound level is reduced. By using perforated tube the fuel consumption remains same as conventional system. By using water as a medium the sound can be lowered and also by using activated charcoal in water we can control the exhaust emission to a greater level. The water contamination is found to be negligible in aqua silencer. It is smokeless and pollution free emission and also it is very cheap. This aqua silencer performance is almost equivalent to the conventional silencer. It can be also used both for two wheelers and four wheelers and also can be used in industries.

Nutrition and Healthy Eating Habits Essay

Nutrition and Healthy Eating Habits Essay Nutrition and Healthy Eating Habits Essay Vegetarianism: A Way of Life Jimmy Thompson COMM/215 August 27, 2013 Gerry McFarland Vegetarianism: A Way of Life Many years ago, the human diet consisted mainly of plants, such as vegetables and fruits; the diet also consisted of nuts, grains, and legumes. As newer foods and places such as fast food chains were developed, the diet began to grow into a more complex and unhealthy way of eating. This new way of eating has increasingly taken a toll on human lives, as well as the life of planet earth. This is one of the many reasons that I chose to become a vegetarian. Industries, such as fast food chains, have sadly caused obesity in humans, especially in the United States, which has become an epidemic amongst children and adults. There are many more factors other than fast food that are to blame, but it is ultimately up to an individual’s personal choice as to whether or not they choose a healthy way of life. Fast Food Industry Sugar, high fructose corn syrup, harmful chemicals and other bizarre things are what fast food companies such as McDonalds and Burger King are feeding to their customers. These absurd chemicals have been known to be some of the causes of obesity, which has become an extreme epidemic in America. Healthy eating habits have not been gaining enough buzz from the general public, but it has gotten much better with the help of many organizations. The Center for Disease Control and Prevention has listed on their website that thirty-seven percent of American adults are considered obese and seventeen percent of American adolescents are obese. This is drastically higher compared to recent years and is embarrassing compared to other countries. Obesity is associated with diseases such as cancer, heart disease and diabetes, and eating healthy can certainly decrease these aliments (Nursing Standard, 2013). It is very concerning what people continue to put into their bodies, espec ially when there have been news articles and reports on what is in the food that people are consuming. Although consuming fast food is convenient and can often times be cheap, it is very harmful to the body, as well as the planet. Even though fast food chains have made changes in some of the products they offer, they still have not changed the way their food is being produced. There are many people who try and justify their reasoning for eating fast food. They say they cannot afford to eat healthy, but comments like those are nonsense, because eating healthy is in fact not expensive and cost much less than eating fast food. The world has been succumbed to convenience and many people will do whatever they can to accomplish something in as little time as possible; therefore, eating fast food satisfies that need for convenience because it takes no time to purchase it and then devour it. Unfortunately, it is causing great harm to the bodies that are consuming fast food. Fast food chains need to take responsibility for the obesity rates in America, which surprisingly, McDonald’s has. According to Strategic Direction (2005), McDonald's seems willing to accept a share of the blame for the obesity problem. Indeed, the company has gone as far as saying that eating too many of its burgers is definitely bad for you. If this is the case, fast food companies need to ensure they are using organic products in their food. Resources The American public is uneducated when it comes to eating healthy and knowing how to prepare cost friendly meals. There are resources today that are reaching out to educate, such as the Let’s Move initiative. This initiative was created by Michelle Obama and it is empowering people of all ages to get up and move. The program teaches through exercise, which is one of the most important factors to a long and healthy life. The First Lady’s program is very motivating and it is inspiring individuals from all walks

Exam questions - Essay Example Times have changed, and this has brought issues such as environmental concerns (Shaheena, 2008). The following are some of the other trends that have arisen in the sphere; Organizations under Constant Scrutiny One notable development over the past decades is that organizations are continually loosing grip of the information that reaches their customers. This is the information era, and everyone seems to know more than they actually do. The fact that people are constantly seeking information, the numerous channels of passing information, and that there is freedom of expression in most nations forces most organizations to lose some grip on the information that gets to the public (Thomas, 2009). This is the reasons why organizations are competing with these outside sources of information by using the same means such as setting up websites along with utilizing popular social media sites. Responsibility as an Organizational value During the past few decades, many organizations have incorp orated the elements such as sustainability, responsibility, and respect into their workplaces. Initially, only a handful held this trait since their work demanded so. Examples of such organizations included Ben & Jerry’s, Starbucks, and Tom’s of Maine. ... In 1943, Johnson & Johnson was accredited as the first organization to act responsibly towards the community. While the CSR department is deemed as the core steward of this attribute, present trends depict that organizations are using them internally requiring everyone to exhibit good citizenship. Recognition that CSR can foster skills in the workplace It is said by some economic experts that the world economy is still trying to heal its wounds from the economic downturn of 2008. During this period, most multinationals focused on the validity of every job and employee within their realm. The recession caused most organizations of this nature to limit the leadership and training initiatives. This caused a challenge since the heart of any organization can be stated as its employees; they put the welfare of the organization in a destitute place whenever they are not advancing in any way. The future seemed obscured for most of these organizations up until some discovered that CSR held a key to the issue (Thomas, 2009). Organizations such as IBM used CSR to indirectly train its employees. The technique was that activities embedded into CSR such as volunteering are imperative in building skills in employees; mainly through skill-based and pro-Bono volunteering. For instance, IBM commissioned approximately a hundred and fifty thousand workers to perform community service all across the globe. This technique was assumed by other organizations who sought to benefit in the same way. It was possible to do so because the workload was dismal thanks to the recession, but it gave organizations something to mull about. Presently, organizations can consent some of their workforce to this service to the society and consequently develop skills without
