Economics for Business and Management Essay Example | Topics and Well Written Essays - 1000 words

Economics for Business and Management - Essay Example The demand curve may take an unique shape like that in figure 3.5 for two major reason, firstly if the product is of an inferior nature. Secondly if the customer believe that even though the price is high the quality is worth it, hence they demand buying more. With respect to figure 3.6 The demand curve will happen to shift incase at every and each price the customers are prepared to buy more or less than before (GILLESPIE, 2011) Similarly supply curve combines all the goods produced and offered for sale in the market against given price (THOMPSON, 2010). Goods are only sold when profit of the producers equates costs or is greater than that which means supply curve can be indicated as social cost. People have to pay a certain cost to attain some benefit. The intersection of demand and supply provides market equilibrium at which equilibrium price and equilibrium quantity is determined (AFRIAT, 2003). Now if the equilibrium conditions are dismantled; the economic efficiency will also b e lost in the process such in the case of benefits and costs, there may be welfare loss or even welfare gain too. Assuming a condition where minimum price is set above the equilibrium prices indicate setting a price floor for a certain commodity. Suppose government introduces price floor on cotton to protect the small producer, this will result in increasing prices where consumers will be required to pay higher prices that the good’s actual worth. In an open competition the prices might have shifted down to equilibrium but due to price floor that won’t be possible. In Fig. 1, Pf price is set to be fixed at $4 where quantity supplied is 2kg Cotton and demand is 1.5kg while at equilibrium consumers might have 1.8Kg cotton at less price of $3.2. So, with an increase in price over equilibrium has reduced the social welfare as the surplus cotton is not demanded yet the consumers are required to pay higher for limited quantity (WESTON & TOWNSEND, 2009). The social cost of co tton is more than the social benefits which sums up the negative net welfare at large. Question 2 (Why a profit maximizing firm produces the output that equates marginal revenues to marginal costs? (MR=MC)) In monopoly or even in perfect competition, a firm optimizes its profit and output where marginal cost and marginal revenue are equal (GRIFFITHS & WALL, 2011). All approaches to analyse maximized profits end up at MR and MC. If we examine total revenue and total cost; they are also summed up by the marginal. Secondly marginal curves provide the slope of change by which accuracy can easily be maintained. In perfect competition firm has MR=MC at two point. First at output level 1 and at output level 7. Firms always prefer the highest output to be produced while secondly at output level 1, though MR=MC but the total cost is below total revenue and the profit at this point is also negative (GILLESPIE, 2011). Finally the maximized profit require the biggest gap and difference between revenues and costs which can only be attained at point where MC=MR as in Fig. 2, at max. profit Average Cost is farthest away from Average Revenue. Mathematically, when MR=MC, after taking 1st derivative the gap between Total Revenue (TR) and Total Cost (TC) is the positive highest. Which after 2nd derivative becomes negative indicating the maximum profit while no other

The Teacher as a Hero Essay Example for Free

The Teacher as a Hero Essay T here are heroes and heroes, national and local. Some of them are born, others are made. Many are still living while many others have long been gone. It is to the latter that monuments and museums were built to keep alive their memory in our hearts and mind. Public buildings, parks and plazas, streets and a few provinces have been named after them. Important dates and events are usually marked red in the calendar to remind us of their birth or death anniversary. During the celebration of these events, program speakers take turns extolling to high heavens whatever good they had done for the country. Sad enough the hero who is apparently taken for granted and therefore unsung is the poor teacher. Not having a pedigreed name, she has no influence, no power. She is regarded as belonging to the marginalized sector of society. Tactless people look down on her with contempt saying, â€Å"She’s only a teacher. † After all, unlike OFWs, teachers do not contribute to the national economy. What many do not seem to realize is that a teacher is truly a hero in her own way. For a teacher is not only about her lesson plans, her teaching methods, strategies and techniques. A teacher is also about her personal character, her values and her attitude. And more importantly a teacher is also about her missionary work which entails a great deal of sacrifice on her part and her family. Indeed, the pro-bono services that she renders involve numerous risks to life and limb. We have heard of teachers who were kidnapped for ransom, forced into marriage under pain of bodily harm, physically abused and the unfortunate, even beheaded. I remember a male teacher who reprimanded a student for provoking trouble in class. That afternoon the huffy father with fire in his eyes sought the teacher in school and mercilessly hacked him to death. I had a relative who was summoned to the Comelec office in Manila and made to explain her inadvertence to affix her signature on a pair of election forms. The financially distressed teacher was forced to take a long-term loan which she used to pay for her transportation fare, board and lodging while in Manila. In the meantime her family had to be sparing and frugal in order to tide them over until such period that the loan was fully paid. While other government employees are off after five, the teacher spends long hours of work at home writing lesson plans, checking test papers or preparing visual aids and similar teaching devices. Compared to those who work in the comfort of their office, thousands of our teachers go on long hours of journey to their far-flung stations over hill and dale, many times in harsh weather condition. It is no wonder that many of these teachers become decrepit long before their age or they get pitifully sick before retirement from the service. And yet their take-home pay is a mere pittance. Any increase in their starvation salary comes far apart and in trickles because this is dependent upon the members of Congress who remember the teachers only on election time. Come May of next year teachers will again be called upon to man the electoral ramparts of our democracy. They will be there to help safeguard the sanctity of the ballot, armed only with the nobility and integrity of their profession. Whatever people say to the contrary, the teacher as a hero is ready to lay down her life for the sake of country sans a loud flourish of trumpets. I salute our teachers as heroes, living or dead! ANTONIO A. MORAN of Camalig, Albay is a retired general education supervisor of the Department of Education.

David Beckham :: Biography Biographies Bio

David Beckham David Robert Joseph Beckham OBE (born May 2, 1975) is an English footballer born in Leytonstone, London. He is a midfielder for Real Madrid and captain of the English national team. He is noted for the quality of his crossing and ability to hit free-kicks and corners, particularly at long-range free-kicks and also for his marriage to a Spice Girl. He has played most of his career for Manchester United. Although there are arguably many better current players in world football none are as famous. Manchester United 1995-2003 Beckham first signed a YTS (youth training scheme) contract (this is similar to an apprenticeship) with United in 1991, and made his League debut in 1995, aged 19. The next year he helped the side to the Premiership and FA Cup trophies and to their dominance of domestic football. In the 1998-99 season, he was part of the United team that won the "treble" - Premier League, FA Cup and Champions League, a feat unprecedented in English football, which earned the club's manager, Alex Ferguson, a knighthood. In total, Beckham scored 86 goals in 397 games for Man United, a rate of roughly 2 goals every 9 games, highly commendable for a midfielder. Club Career Real Madrid 2003-present On June 17, 2003, Beckham signed a four-year contract with Real Madrid of Spain, potentially worth up to â‚ ¬35 million (Â £25 million, USD 41 million). Plus 2. Apart from benefiting from his football ability, this transfer gives the Spanish club an opportunity to profit from merchandising, especially in the Far East, where Beckham is enormously popular, and Manchester United have until now had the lion's share of interest. It is probably no coincidence that Beckham was transferred just before Real started a far-eastern tour, but it would be very unfair to say that his marketing potential alone was the only reason for his transfer. At the time of the announcement of his transfer to Real Madrid, Beckham and his wife (Victoria) were on a week-long tour of Japan, Vietnam, Malaysia, and Thailand promoting beauty products, chocolate, motor oil, and mobile phones, which it was reported would earn them more than the entire first year of his Real Madrid contract. (Western journalists are excluded from the Japanese "press conferences" organised by his sponsors because of the embarrassment they would cause him in the West.) He successfully completed the transfer on July 1 and was presented with the squad number of 23 on July 2.

Honesty :: essays research papers

It was my aunt who taught me the meaning of honesty. Not because she actually was honest, but because she lied all the time. I think she felt that the easiest way out of any given situation was generally the best way out. For her, that meant telling a lie that sounded believable. As a young child I thought it was cool to lie and get out of things so easily and being around my aunt was the main problem. Naturally, when ever I would come to her with a problem, concern, or a question wondering what I should do, she would always tell me to make up a good lie and run with it.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Aunt Ruby, I told April that I would go to the movies with her, but I would rather go to Jessica’s house and go to the mall with her.†   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Tell April you’re sick,† she would say. And most often I would. But I didn’t seem blessed with her lack of principles. On many occasions April would find out that I really went to Jessica’s house and to the mall without her. These occasions taught me that it is more painful to be caught in a lie than to tell the truth in the first place. I wondered how it was possible that my aunt had never learned that lesson that I had just learned so painfully and so easily.   Ã‚  Ã‚  Ã‚  Ã‚  I started thinking of all the lies that I’d heard her tell. I remember the time she told her friend that her favorite shopping mall had closed, just so she wouldn’t have to see her there anymore and have her approach her and talk for five minutes. The time she told my Uncle that she loved the new purse he had gotten her for her birthday. The one that really takes the cake is when she told her friend Patty that the car was down and that is why she hasn’t been to see her in a couple of weeks. The thing that I don’t understand is why you have to lie to the people you love if you don’t like or want to do something. What bothered me after awhile was how she incorporated me into her lies. Like the time she called the school and told them I wouldn’t be there today because I had a dentist appointment, when in fact, she wanted me to baby sit my little cousin so she could go get her hair done.

Coffee Bean Inc.

Coffee Bean, Inc. (CBI), is a processor and distributor of a variety of blends of coffee. The company buys coffee beans from around the world and roasts, blends, and packages them for resale. CBI currently has 40 different coffees that it sells to gourmet shops in one-pound bags. The major cost of the coffee is raw materials. However, the company’s predominately automated roasting, blending, and packing process requires a substantial amount of manufacturing overhead.The company uses relatively little direct labor. Some of CBI’s coffees are very popular and sell in large volumes, while a few of the newer blends have very low volumes. CBI prices its coffee at manufacturing cost plus a markup of 30%. If CBI’s prices for certain coffees are significantly higher than market, adjustments are made to bring CBI’s prices more into alignment with the market since customers are somewhat price conscious.For the coming year, CBI’s budget includes estimated manuf acturing overhead cost of $3,000,000. CBI assigns manufacturing overhead to products on the basis of direct labor-hours. The expected direct labor cost totals $600,000, which represents 50,000 hours of direct labor time. Based on the sales budget and expected raw materials costs, the company will purchase and use $6,000,000 of raw materials (mostly coffee beans) during the year.The expected costs for direct materials and direct labor for one-pound bags of two of the company’s coffee products appear below: |   | |   | |Mona Loa | |Malaysian | | | |Direct materials | |$ 4. 0 | |$ 3. 20 | | | |Direct labor | |0. 30 | |0. 30 | | | CBI’s controller believes that the company’s traditional costing system may be providing misleding cost information.To determine whether or not this is correct, the controller has prepared an analysis of the year’s expected manufacturing overhead costs, as shown in the following table: |Activity Cost Pool | |Activity Meas ure | |Expected Activity for the Year | |Expected Cost for the Year | | | |Purchasing | |Purchase orders | |1,710 orders | |$513,000 | | | |Materials handling | |# of Setups | |1,800 setups | |720,000 | | | |Quality control | |# of Batches | |600 batches | |144,000 | | | |Roasting | |Roasting-hours | |96,100 roasting hours |961,000 | | | |Blending | |Blending-hours | |33,600 blending hours | |402,000 | | | |Packaging | |Packaging-hours | |26,000 packaging hours | |260,000 | | | |Total manufacturing overhead cost | |$3,000,000 | | | Data regarding the expected production of Mona Loa and Malaysian coffee are presented below.    | |  Ã‚   | |   | |Mona Loa   | |   | |Malaysian | | | |Expected sales   | |   | |100,000 pounds | | | |2,000 pounds | | |Batch size   | |   | |10,000 pounds | | | |500 pounds | | | |Setups | |3 per batch | |3 per batch | | | |Purchase order size   | |   | |20,000 pounds | | | |500 pounds | | | |Roasting time    per 100 pounds | |   | |1 hour | | | |1 hour | | | |Blending time   per 100 pounds | |   | |0. 5 hour | | | |0. hour | | | |Packaging time   per 100 pounds | |   | |0. 1 hour | | | |0. 1 hour | | | 1.Using the direct labor-hours as the base for assigning manufacturing overhead cost to products, do the following: a. Determine the predetermined overhead rate that will be used during the year. b. Determine the unit product cost of one pound of the Mona Loa coffee and one pound of the Malaysian coffee. 2. Using activity-based costing as the basis for assigning manufacturing overhead cost to products, do the following: a. Determine the total amount of manufacturing overhead cost assigned to the Mona Loa coffee and to the Malaysian coffee for the year. b. Using the data developed in 2(a), computer the amount of manufacturing overhead cost per pound of the Mona Loa coffee and the Malaysian coffee.Round all computations to the nearest whole cent. c. Determine the u nit product cost of one pound of the Mona Loa coffee and one pound of the Malaysian coffee. Write a brief memo to the president of CBI explaining what you have found in (1) and (2) above and discussing the implications to the company of using direct labor as the base for assigning manufacturing overhead cost to products. MEMORANDUM To:The president of CBI From: Date: Subject:the implications to the company of using direct labor as the base for assigning manufacturing overhead cost to products. 1) Per pound cost of the Mona Loa coffee and the Malaysian coffee as per traditional costing system is $ 6 and $ 5 respectively. ) The manufacturing overhead assigned to each pound of the Mona Loa coffee and the Malaysian coffee is same because the direct labour hours required for manufacturing each pound of coffee are same 3) Per pound cost of the Mona Loa coffee and the Malaysian coffee as per Activity based costing system is $ 4. 83 and $ 7. 15 respectively. 4) Following are the implication s to the company of using direct labor as the base for assigning manufacturing overhead cost to products: 1. Price determination under existing costing system (using direct labor as the base) is not accurate. Under activity based costing cost is calculated more accurately than existing product costing system. 2. Higher prices of popular product affect market adversely.As the customers are price conscious company can sell Mona Loa Coffee (which is more popular) at lower price and can increase its market share if the cost is calculated accurately. 3. As company uses relatively little direct labour, direct labour is not an appropriate basis for applying overheads to products. 4. By using activity based costing company can discontinue its non-profitable products or suggest appropriate price for those product 5) Activity based costing allocated indirect cost more accurately . It helps in reducing the cost by eliminating unwanted activities Helps in improving product and customer profitab ility. Activity based costing helps in forecasting and planning.

Reflective Journal Essays

Reflective Journal Essays Reflective Journal Essay Reflective Journal Essay Essay Topic: Reflective Reflective Journal Detailed description as if to an outsider. Often you will use your journal to record detailed descriptions of some aspect of your internship environment, whether physical, behavioral, or organizational. When you write them, you will not have a clear idea of what you will make of these details, but you will sense that they might be important later. These descriptions should sound as if you were describing them to someone who was never there. Journals allow you to sound naive. At times you will want to speculate as to why something that you have observed firsthand is as it is. You might derive your explanation from a lecture you have heard, a book you have read, or your own reservoir of â€Å"common sense†. Having posited an interpretation, you will want to continue with your detailed observations on the topic to see if you want to stick with your hypothesis or alter it. Journals allow you to change your mind. Here are a few of the ingredients that go into a keeping a great journal: * Journals should be snapshots filled with sights, sounds, smells, concerns, insights, doubts, fears, and critical questions about issues, people, and, most importantly, yourself. Honesty is the most important ingredient to successful journals. * A journal is not a work log of tasks, events, times and dates. * Write freely. Grammar/spelling should not be stressed in your writing until the final draft. * Write an entry after each visit. If you can’t write a full entry, jot down random thoughts, images, etc. which you can come back to a day or two later and expand i nto a colorful verbal picture. Key questions to answer Describe your experience.

This paper reflects on the literature review findings concerning the impending factors of international mobility. It analyzes how the learning processes and experiences through the review relate to the business research, academic development, professional development and personal development. 2.0 Learning Experiences of Business Research According to Bolton (2005: 5) learning is the acquisition of new or modification of existing knowledge, preferences, values, skills and behaviors. This is mostly referred to as a process or an experience. This is because learning is continuous and it is acquired through theory and practice (Sunstein Chiseri-Strater, 2007:15). Learning is important as it enables the learner to acquire knowledge on how to handle real life situations whether it is in their personal lives, social lives or professional lives. The learning discussed in this paper will not only reflect on the literature review, but it will also reflect on the research, language, process, design, sources and collection of data, data analysis, report writing and presentation, and the ethics parts of this business research. This learning enables one to analyze and understand the intended findings of the particular field (international mobility for this case) (Hume, 2009). 2.1 Learning Processes of Business Research During this research, I could not ignore the fact that it was not just a matter of acquiring information and analyzing it. Having the research question, knowing the right methods to use during the research, proper analysis and making a cohesive conclusion is the most important aspects of a research. Spalding and Wilson (2002) feel that it is crucial for the researcher to reflect on the situation at hand before embarking on it. Through the research, one identifies that there are areas that have more significance as compared to others. However, every stage should be taken into consideration. This enables the researcher to have strong and justifiable results and conclusions. Table 1 Most interesting topicsReason for ChoiceLanguage of business Collection of data Data Analysis Literature Review Reflective Journal Report Writing Chapter Most Difficult The Language This stage is the most interesting as the researcher picks up a hypothesis or hypotheses so that my research can be narrowed. In this case, it not just about globalization within the organization, but it has been narrowed down to international mobility. Although it can be challenging coming up with the specific questions to be answered, it is also interesting because it tests ones capability of being unique. This is the second most interesting part of the research as it involves a lot of interaction with the real world so that one can be able to collect first hand information. Although it has its own challenges, it gives me time to come with my own data. This topic allows one to analyze the data he/she has collected. It gives the researcher a chance to put what he/she leant in theory work to what they have collected (Otienoh, 2009: 479). Literature review enables the researcher to find out about the targeted research topic in accordance to what has been written about it (Warhurst, 2008). The interesting thing about this topic is that one has a chance of gathering as much information as they can about the research topic. It is like being in one room with all the professionals in the field of international mobility. This is a very interesting area as I am supposed to give a reflection of what I encountered through out the research. This includes the difficult areas and the interesting ones. This chapter enables me to give a comprehensive report about my journal. It tells of what cannot be told in the research itself. Although it is listed as an interesting area, the language chapter is the most difficult. This is because I had to formulate the thesis statement or the hypotheses of the research. Having a wrong hypothesis may lead to a bad or ineffective research project Table indicates the areas that are most interesting to encounter (the table is a self generation) 2.2 Learning Processes of Business Research It is significant to appreciate that one cannot just decide to conduct a research with no knowledge of how to conduct it. This is how the class notes, self reading, and the class lectures play a major role. Through the literature review assignment, one not only reads about conducting a literature review, but he/she goes ahead and does a literature review on a business topic. Each topic of business research enables the researcher to understand its application to the research and how to achieve the most concrete results than one can come up (Mills, 2008). It is not enough to know the diverse topics in business research, but it is important that the researcher knows how to apply each topic to the research process. 2.3 Learning Reasons of Business Research It is essential that I learn business research. Apart from it being examinable since it is part of the learning modules, it is significant to my future studies. Many business modules require the student to carry out research work in order to show that they have understood a particular module in a given learning period. This learning is also significant as it enables a student to understand other research works. Reflecting on these topics will enable me to understand complex research works that will be encountered in the future (Kalliath Goughlan, 2001: 62). In as far as research work is concerned; the topics offered are the foundation to the field of business researching. This foundation gives me an idea of what to encounter such a module in the upper years. It is up to me to do more self reading so that I may understand the topic in a deeper way and more clearly. 2.4 Learning Experience in Relation to Professional Development Sunstein and Chiseri-Strater (2007) indicate that research work should not only be a benefit to the one researching, but it also benefits other parties whether in that field of the topic being researched or in other fields. In as far as academic development is concerned; this reflective writing enables me to evaluate what I have learnt in this module and whether I can use it to develop others academically. As earlier mentioned, learning business research will enable me to develop better ways of conducting future complex researches in the academic years to come. This module offers a foundation in this field. Through this reflective writing, I am able to see that my skills and knowledge id gradually increasing. The previous mini-researches that I have conducted were just done without following a particular process. The process is now clearer. It is also good to appreciate the areas of merit and difficulty (Mills, 2008: 685). The areas of literature review, collection of data and analyzing it, report writing, ethics in business, research design and research process do not pose such a major challenge to. However, the language area is highly challenging. This is due to the parts where one has to come up with variables or hypotheses. If the research is examinable, poorly developed hypotheses or variables may lead to poor marks. 2.5 Learning Experience in Relation to Professional Development Sunstein and Chiseri-Starater (2007: 38) are also confident that any research learning done in school plays a crucial role in an individual’s profession or career path. This learning and reflection will enable me to conduct research that is not only significant to my organization but also to my field of interest. The skills and knowledge given make the research work much easier as compared to having no knowledge at all. In the business field, there are those who specialize in researching on the different issues in the business arena or affecting business. If I choose to specialize in research work, then this module is building my profession. As indicated earlier, the language topic of business research poses a challenge to me. However, by the time I am through with this course, through self reading and practice, I will have overcome this challenge. 2.6 Learning Experience in Relation to Personal Development Greiman and Covington (2007: 117) indicate that reflective writing enables me to understand my areas of improvement and those that need to be improved. Through these topics, I have been able to be more organized thus improving time management. I know when to come up with the hypotheses, review literature, collect data, and analyze it, amongst other steps. It is not only a matter of getting the work done, but also getting it done in the right way. There are areas of weaknesses such as coming up with new ideas faster than I already am. For example, it takes me time to come up with a good variable or hypothesis thus the one ends up taking time meant for other steps. However, I am able to complete my work in time. This module has also enabled me to improve on my general time management. 3.0 Conclusion Such a reflection journal enables one to examine an area of study (Greiman Covington, 2007: 115). This reflection enables one to understand the reasons of studying this module as far as business research is concerned, knowing the areas of strengths and weaknesses and understanding its relationship to the academic, professional and personal aspects of a person. Knowing how to carry out a research and to carry it out in the right way is as significant as the research itself. The study is significant to what I will encounter within this course, in future academic works to be done and in my area of profession.

How to conclude a report like a rock star - Emphasis

How to conclude a report like a rock star How to conclude a report like a rock star Grab a pair of headphones and a lighter to wave in the air. Ready? Then let’s rock. When you’re trying to bring your report to a conclusion, do you ever feel like   Paul McCartney at the Olympics opening ceremony, rehashing the same points (‘na na na nananana ’) as the audience sneaks quietly for the exits? Or do you take the John Lennon approach in   I Want You (She’s So Heavy) and crash to a sudden halt? Endings can be tough to write, but they’re so important. You want to send your reader away thinking about what they’ve read – or even persuade them to make a decision right there and then. Going out with a whimper isn’t an option. Heres Neil Sedaka demonstrating just how awkward a bad ending can be –   Breaking up is hard to do indeed. Four types of conclusion: PQRS If your report includes recommendations, you’ll already have stated them in the executive summary and supported them throughout the document. So your conclusion should contain no surprises – no Brotherhood of Man-style twist. There are four basic types of conclusion you can use, summed up by the letters PQRS:   Predict,   Quote,   Repeat or   Summarise. Predict the future (Take my hand and we’ll make it I swear) There are two main ways you can use predictions. If your report is about a decision already taken, you can use the ending to sum up the effects you expect to see. For example: ‘The council continues to expand its recycling scheme at an incredible rate. We will soon be recycling over 40 per cent of our waste.’ But if the purpose of your report is to persuade the reader to take a certain action, predicting what will happen if they don’t can be a persuasive tactic. For example: ‘Unless we expand our recycling scheme, we are almost certain to fall short of our targets for this year and to perform worse than both of our neighbouring councils.’ Then follow this up with a prediction of how things will be different if they take your advice. You’ll already have mentioned this in the body of the report, but you should crank it up a gear in the conclusion. Think   Livin’ on a Prayer, where the key changes for the final chorus. (Getting a shaggy perm is optional, but we’d admire your dedication.) Quote (Who’ll come a-waltzing Matilda with me?) If you do it with care and justification, ending with a quotation can be powerful. But don’t be tempted to stray into show-off territory; this isn’t the time to demonstrate your encyclopaedic knowledge of Latin or Shakespeare. A relevant and pithy quote from someone influential and well-informed, however, can be persuasive. It could be someone youve already cited in the report, or someone new. For example: ‘As the Chairman of Lambeth First says: â€Å"The Lambeth No Knife Charter won’t on its own stop people carrying knives. But if we can make it hard for people to get hold of knives and reduce the number in circulation, then that is a step in the right direction.†Ã¢â‚¬â„¢ This works on two fronts: first, it reinforces your message, showing that others support you. And second, it offers a slightly different angle, and often a chance for a personal opinion. Here are The Pogues, doing it very well in Eric Bogle’s   And the Band Played Waltzing Matilda. After seven-and-a-half minutes of the horror of war, it cuts to the original song, with the old soldier – now a double amputee – asking ‘Who’ll go a-waltzing Matilda with me?’ Repeat a major issue (Seriously, she is totally buying a stairway to heaven) This can be tricky. You don’t want your reader to feel like you’re repeatedly bashing them over the head with the same message. But at the same time, you do want them to walk away with that message in their head. Basically, you want to bash them very gently, without them noticing. The secret is to keep it brief, to-the-point and memorable. For example: ‘Today, Lambeth – like all councils – faces a major challenge due to the increased uptake of adult health and social services. It is vital that we secure additional funding.’ Go for the Led Zeppelin effect. When Robert Plant finishes his slow, deliberate howl at the end of   Stairway to Heaven, you’re in no doubt about what the protagonist is buying, but you don’t feel as if you never want to hear about a stairway ever again. Summarise (Where do we go now?) When summarising, resist the urge to go over all your points again, and keep it brief. Your summary should just bring together your main points, and reinforce any recommended plan of action. For example: ‘The new programme aims to make â€Å"every Lambeth child a talker† by involving parents as well as professionals in children’s language development. In the first two years it will concentrate on 20 groups of pre-school children, but it will then link with other groups to pass on good practice.’ This example includes both a summary and a prediction – you can combine the different endings to make the right conclusion for your document. Most importantly of all, you’re looking to be concise, memorable and powerful. Think the impact of   Sweet Child o Mine, but with less ‘where do we go?’ and more ‘this is where we go’. Conclusions, in conclusion Most importantly of all, your ending needs to be arresting and to leave a lasting impression. Not for you, the gradual fade out. Use the techniques above and aim for a grand finale. Rock on! Do you have any tips for writing a great conclusion? And what’s your favourite (or least favourite) song ending?

Filtering the Net essays

Filtering the Net essays Over the last several years many attempts have been made to put a limit on what can be viewed on the Internet. In 1996, it was the Communications Decency Act and in 1999 the Child Online Protection Act. Both were shot down because they were said to violate the first amendment right to free speech. Should the government have the right to limit what children view on the Internet? The government does this in places like schools and libraries. Filtering the Internet has become commonplace in most schools and libraries. Internet filters are software that puts restrictions on what can be viewed by using a vocabulary list. If a word on a website is in this list than the filter kicks in and the site cannot be seen. This has caught the eye of many different groups of people, such as the Family Research Council. This is what the Family Research Council has to say about Internet filters software that filters out objectionable Internet content will save public libraries from becoming sex havens where children and adults routinely go for pornography. Then there are groups with totally opposite views, such as the Gay and Lesbian Alliance against Defamation. When asked about Internet filters they said filters are imperfect and can harm children by creating a false sense of security and censoring some important information. The alliance just feels that if you deny children access to certain things, it will hurt them in the long run. Some teachers in New York City are also against the Internet filters because they said the filters would not allow access to many educational sites. There are also people who think the Internet filters are just a violation of free speech. Most people think that libraries and librarians were the ones that brought about these filters, but that is just not true. The American Library Association released this statement on internet filters it does not endo ...

Analysis at the operational level the the presecution of the Allies' Essay

Analysis at the operational level the the presecution of the Allies' defence of Crete in 1941 and identify the enduring lessons - Essay Example Moreover, the leadership, going into the battle already defeated, did not bother to put together a coherent strategy for battle, but, rather, seemed to make it up as they went along. These are all reasons for the defeat, and lessons that were learned. Nevertheless, as the Allies did delay Hitler’s forces for a few weeks, which, in turn, delayed Hitler’s invasion of the Soviet Union, which was the turning point of the war, one could say that the battle of Crete set into motion a chain of events that led to Hitler’s destruction. This paper will examine the reasons why Crete was fought? and how the British tried to defend it? coupled with an analysis of the mistakes made and an analysis of why the battle might not have been so bad after all, as it delayed Operation Barbarossa, the invasion of the Soviet Union. Why Germany Wanted Crete and How Germany Got Involved in Greece The Battle for Crete had its roots in a demand by Benito Mussolini, Italy’s fascist dic tator, to Greece to allow an Italian occupation of Greece in October of 1940. When the premier of Greece, John Metaxas, defied this request, the Italians began the invasion of Greece (Woodhouse, 1976, p. 16), a move that would prove to be a â€Å"disaster† for Mussolini (Heckstall-Smith, A. & Baillie-Grohman, H.T., 1961, p. 15), and would make Mussolini a â€Å"laughingstock† in Greece (Hart, 1996, p. 87). This move by Mussolini was precipitated by Germany sending soldiers into the Ploesti oilfields, which enraged Mussolini enough for him to launch this invasion (Mazower, 1993, p. 15). The reason that the German action of sending soldiers to Greece so piqued Mussolini was because Mussolini was jealous of Hitler, and felt that he stood in Hitler’s shadow while Hitler rampaged Europe. While Hitler added Austria, Czechoslovakia, Poland, Norway, Denmark, the Netherlands, Belgium, Hungary, France, Yugoslavia, Bulgaria and Romania to the Third Reich, Mussolini fantasi zed about adding the Mediterranean to the Italian column, while Hitler insulted him by not allowing him access to the fruits of victory. The final insult was Hitler’s occupation of Romania, a move that was done behind Mussolini’s back (Kiriakopoulos, 1995, p. xv). This insult to Mussolini was what initially caused the Italian dictator to invade Greece in 1940, as Mussolini stated that, about Hitler invading Rumania without consulting him that he â€Å"shall pay [Hitler] back with his own coin; he shall learn from the newspapers that I have occupied Greece. Thus equilibrium would be restored† (Cervi, 1971, p. 60). However, this move was unsuccessful, as Mussolini’s troops were defeated and pushed back into Albania (Mazower, 1993, p. 15). Hitler was incensed by the Italians failure (Van Creveld, 1973, p. 57), regarding it as â€Å"definitely a regrettable blunder† (Hinsley, 1951, p. 102), however, as Hitler could not allow his ally to be totally defe ated, he had to launch his own invasion of Greece, which began April 6, 1941 (Kiriakopoulos, 1995, p. xvi). Greece was also important to Germany, as it was seen as a prelude to the Russian campaign (Von der Porten, 1969, p. 109). This campaign proved to be successful (von Mellenthin, 1977, p. 228), as the Middle East,

Ethics of Data-Driven Decision Making Case Study

Ethics of Data-Driven Decision Making - Case Study Example A series of analysis were given to the project manager concerning data on the cost profit and volume analysis. This is a well detailed collection of data that can help the management to decide whether to proceed with the project or reject it. Some case scenarios require the project manager not only to rely on analysis of data but also to rely on ethics of the society to enable effective decision making. This helps to ensure effective production of the vehicles as well as maintaining a good image in the public. A good example is the case of Giant motor company where they are considering retooling two of their three vehicle assembly plants. The project manager should not only rely on the relevant data providedbut on also other areas that many companies fail to assess like the safety of workers, whether the space is enough for the retooling process and so on. If for example the level of space is minimal after hypothetically retooling, this may cause accidents in terms of congestion of w orkers who may compromise safety of workers inside the plant (Streifer& George, Pp 32). Another case that ethical decisions can override data used for decision making is where the new luxury cars been made affect the environment. This can be seen through emissions of carbon monoxide by exhaust pipes. If the level of the gas produced is so intense that it is considered a threat hazard by the society, the management should take an ethical stand not to retool because of the consequences even though they are not going to realize the profits they had anticipated. This is referred to as moral sensitivity. Another area we come across ethics of data-driven decision-making is in case 4d of Muskoka land development. This case study is about a group of part time MBA students who are following an opportunity to invest in recreational properties in Muskoka Ontario. After undergoing research of the area, they come up with two sites that have potential to bring large returns in profit (Streifer& G eorge, Pp 56). They collect data on both areas and come up with a list of all the expenses and costs information based on development plans for each site. In this case, we can clearly say the students are about to make a decision on whether to go ahead with the project based on the data they extracted from their research. In this case, to some extent, it is not appropriate to rely on data to make decisions concerning investment of recreational properties especially in site A due to the following reasons-: Muskoka is fully equipped with Mother Nature’s best like lakes, forests and so on. If the students decide to invest in site A they will be messing up the balance of nature in that area. This is where ethical decision making comes in handy. In my opinion, the students should ask themselves if they are ruining nature if when developing their plans, they happen to cut down trees in the area which is a life source for many animals that live in that habitat. By destroying trees, to make roads in such an area may cause alternations in many animals’ lives, which may trigger different kinds of reactions. Another question would be if there are any small rural communities that live in that area? If there are, the students risk displacing a whole community so as to make profits and in the process causing a long string of problems between them and the community. This is unethical and is considered moral decay. The students should therefore consider developing in site

Public Policy Current Events Analysis Essay Example | Topics and Well Written Essays - 1000 words

Public Policy Current Events Analysis - Essay Example Chesapeake Bay is a crucial waterway. The bay is presently in critical condition and is facing a lot of challenges especially through pollution. Perhaps, the greatest source of pollution arises from increased nutrients in the bay especially phosphorus and nitrogen. Though, these nutrients are fundamental to sustain aquatic biological growth, if present in quantity excessive of the basic requirements, like in the Chesapeake Bay, they lead to excessive growth of algae and phytoplankton. This has had a twin effect. The algae have blocked sunlight, thus, preventing penetration to the deeper end water, thus, compromising the growth of bay grass. Secondly, when the algae die they use available oxygen in the deeper areas for decomposition creating dead zones, whereby the dissolved oxygen levels becomes too low to sustain marine life. This has led to dwindling of fishery resources in the bay. From the documentary, it is clear that these nutrients arise from a horde of sources notably from ag ricultural farms and sewage.Chicken manure is loaded with nitrogen and phosphorus which when carried to the bay by the rivers culminates in the dead zone. Hedrick smith also points to the fisherman as a source of the problems facing the Bay. He states that humans have drastically overfished the fisheries resources. This information has been known by the formal policy makers for quite a long time. Charles fox, EPA assistant administrator between 1998 and 2001, admits to this. They tried several methods to combat the problem such as trying to enact regulations and laws and initiating programmes to treat the sewage system. Nevertheless, they have been unable to combat this menace due to a horde of factors. Key among them is the lack of political will, despite available information showing what is necessary to save Chesapeake Bay. Leon Billing, US senate staff from 1966 to 1980 compares the same situation to the passage of Clean Water Act, which when it was passed in the senate, and the house, President Nixon vetoed it despite pressure from the people to enact the law to govern pollution. Charles Fox also points to preferential treatment to successful business stating that the Reagan administration had a deregulatory agenda often inviting successful businesses for a list of regulation they would want to relief. Further, he blames the administration for being an obstacle to the operations of EPA, stopping its operations for a period of about seven years and instead appointing people to run the EPA, people who were opposed to its mission. Informal policy actors have played a prominent role too.This is through active lobbying. Leon Billings states that the big chicken companies have hired top guns to lobby against the enactment of any meaningful regulations on the agriculture sector and, thus, influenced policy makers. When the Maryland legislature tried to compel mandatory nutrient management by farmers, they were opposed to the bill. Jim Perdue argues that the bill was a threat to survival of the industry in totality. Other informal policy actors include the public pressure, interest groups such as the non-governmental organization. PART 2 Gay marriage has emerged on the agenda because of both formal and informal actors. Same sex marriage has been a problem in the society for a while. It has captured public interest and as a result led to public debates whether to legalize it or not. With regards to New York, it was made an agenda due to electoral pledges, as

Week 3 Forum Assignment Example | Topics and Well Written Essays - 250 words

Week 3 Forum - Assignment Example mericans in general did not see the need for the US to be involved in the war but were still enrolled because it was an opportunity to prove they were just as capable as their white counterparts. They opted to fight under their French allies because they supported racial equality and gave them the recognition that their own countrymen did not. At this time, the US government did not want African Americans to serve in the war because they believed they did not have the same capabilities as their white counterparts. Despite that, over 400,000 African Americans were in the army, hence, this prompted the white population to view this as a threat and not a contribution resulting in them to not be actively used when the war was over (Rucker and James 89). The early great migration of African Americans from the south was of great significance to date due to the broken promises of reconstruction and a corrupt criminal justice system from the US government. The African American community left their farms and sort greener pastures in northern states because they were more industrialized. They also experienced great loss of their crops due to a severe weevil outbreak. The peak of this movement was between 1915 to 1920 with New York, Chicago and Detroit being most noticeably awfully hit. The northern states were in great need of labor and so their wages were higher than those of the South. The ascent of the Ku Klux Clan likewise served as a real explanation behind the relocation in light of the fact that they were against African American rights and butchered numerous African

Management Research paper Essay Example | Topics and Well Written Essays - 1250 words

Management Research paper - Essay Example The aim of this system and policy was to wade off any interests of Western Conquerors. Some of the modern economic practices developed during the reign of Meiji. It is important to remember that during the Meiji period, the Japanese economy was still in shambles, finishing the remnants of feudalism having endured centuries of closure to foreign investors both directly and indirectly. This system was responsible for the slow technological development in the country. This was because the approach emphasized on building domestic imitation and innovations on Western goods. This system worked at the expense of importing products (McMillan, 1996, 71). The spirit of Meiji era captured the entire philosophy thus Japanese spirit, Western technology. Elements of the spirit and the Japanese culture over flowed to the twentieth century where the autonomy of the economy was evident both at micro and at macroeconomic levels. The ambition was to preserve the traditional character. The national econ omy has a long history of putting measures that restrict the process of bringing imports into Japan both directly and indirectly by investors. This has led to concomitant trade excesses in Japan for many years. This culture trickles down to the where large and complex families own and run most companies interdependently centered on their banking industries. The banks include Hitachi, Sumitomo, and Mitsubishi among many more. Economists agree that theoretically, the business organizations manage import components, raw materials, as well as capital from abroad through their affiliated organizations. Analysis The Japanese management techniques or the Japanese management style refers to a group of Japanese cultural ways of working as well as managerial behaviors after the World War II. Most of these management aspects wee responsible for driving the Japanese economy to the status as one of the world economic superpowers. The economy of Japan is the second largest in world second to that of the United States of America. The management techniques are also behind the growth of Japanese business especially the manufacturing sector. This sector is the most competitive in the world when compared to other manufacturing sectors. However, through the nineteen nineties, Japan struggled through economic hardships and recession leading to some experts in economic matters to question the ability of the traditional Japanese management styles to sustain the economy. The Japanese management technique concentrates on the need to for the information to move from bottom of the company or institution to the top. It is the bottom up approach for flow of information. This process leads to the senior management taking over supervisory roles as opposed to the hands-on system of management. The management style originates in the mid-level of the institution or company then moves upwards to the higher level for approval and ratification. The greatest advantage for this system of management is that the teams tasked with the responsibility of implementing a management policy are involved in the process of developing the same. The rise of a Japanese manager in the management ranks in the company of institution makes him or her more responsible, seems unassuming, as well as unambitious. Evaluation of effective leadership in the Japanese mana

Comparing The End of the Imagination and The Redfern Speech Essay

Comparing The End of the Imagination and The Redfern Speech - Essay Example Arundhati Roy and Paul Keating, to convince the audience to believe in what they are saying, used the strategy of adding emotional appeal to their evidence, and by doing so, has struck the deepest cord of their heart. It is not only the evidence, but the emotions and imagination attached to the evidence, which helps Roy and Keating to win the hearts of the audience, and hence, it will not be wrong to say that it is the emotions, and not just the evidence, that helps person to convince others in the process of communication. Arundhati Roy In her essay â€Å"The end of the imagination,† Arundhati Roy has expressed her strong views against the nuclear tests conducted by Government of India in 1998. Roy has taken aid of strong evidence, through facts, reasoning and future possibilities, to convince the audience about her disapproval towards the nuclear tests. The evidence that Roy has used to convince the audience are discussed below. The consequences of nuclear war The first stra tegy that Roy has used to prove her stand against the nuclear testing by Indian government is the description of the consequences of the nuclear war. Roy has described the horrors of nuclear war in a vivid language. Instead of just using the words ‘destructive’ or ‘harmful,’ she has clearly described how the villages, rivers, wind and human body will be affected by the nuclear war. This vivid description gives a ‘feeling’ of the horrors of nuclear war and creates a clear picture of its consequences. The picture of what really happens after the nuclear war, and how it affects the environment and human beings, shocks the reader. Hence, the clarity of the effects of nuclear war on human body, the atmosphere, on future generation through poisonous radiations and the effects on environment, works as a strong evidence to prove why she is against the nuclear testing. The second evidence Roy uses is by questioning the sanity of men who can get access t o the nuclear weapons. Suicide bomber psyche Indian government had given ‘deterrence’ as a reason for their decision to go ahead with nuclear testing. However, Roy has argued that the theory of deterrence has flaws in it. She has questioned Indian Government’s understanding of the enemy. Roy feels that one cannot consider the enemy to be similar to self. That is, she has expressed her concern over the terrorist groups who are not ‘deterred’ by the nuclear capacity of the enemy as they have a different psyche. She discusses the psychology of terrorists who are ready to die in order to kill. She calls this a ‘suicide bomber’ psyche. Terrorists are so strongly brainwashed to believe in their cause that they do not hesitate even a bit to destroy themselves in order to prove their point. They are ready to perish, and are insane enough to destroy millions of lives. Roy says that if the nuclear bomb gets in hands of such people, then the Ã¢â‚¬Ë œtheory of deterrence,’ proves baseless. To convince this point, she has provided the evidence of death of Rajiv Gandhi. Rajiv Gandhi, the Prime Minister of India, was assassinated by suicide bomber. Using his assassination as evidence, Roy questions the Indian Government’s understanding about the enemy psyche. Roy questions that when even a man of premiere stature like Rajiv Gandhi was not saved by the

A Summary of Quines Problems with Carnaps Philosophy Essay Example for Free

A Summary of Quines Problems with Carnaps Philosophy Essay In his Two Dogmas of Empiricism, Quine addresses what he views as problematic claims made by Carnap. The first problem Quine has with Carnaps epistemology is about his definition of state-descriptions. The problem is in two parts: first Quine says that Carnaps version of analyticity is conditional, because it requires atomic sentences in a language to be mutually independent. The second part of the problem is that, Carnaps attempt to explore analyticity by way of his state-descriptions results in a problematic definition of analyticity, which ends up being more indicative of logical truth. In conclusion, Quine presents a solution to his problems with Carnap positing that the boundary between synthetic and analytic is imagined. In his attempt to define analyticity Quine encounters a problematic attempt at defining the term, by Carnap. Carnap has tended to explain analyticity by appeal to what he calls state-descriptions(195). Carnaps state-descriptions are problematic for two reasons; one reason is that a statement is explained as analytic when it comes out true under every state description(195), this necessitates every atomic sentence to be mutually independent- meaning that two statements that mean the same thing are supposed to exist as two completely separate meanings. However, as Quine points out this would mean there would be a state-description which assigned truth to John is a bachelor and falsity to John is married, and consequently All bachelors are married would turn out synthetic rather than analytic under the proposed criterion(195). This truth gives rise to the second problem of Carnaps state-descriptions, that analyticity as it refers to state-descriptions only works for languages that do not contain synonymous words such as bachelor and unmarried. So, Quine submits that Carnaps state-descriptions are indicative of logical truth, not of analyticity. To generalize, these problems that Quine has with Carnaps philosophical system equate to a single point of disagreement, that there is an absolute distinction between analytic and synthetic. Quine points to our pragmatic inclinations to adjust one strand of the fabric of science rather an another in accommodating some particular recalcitrant experience(207). Quine believes that Carnaps drawing a distinction between analytic and synthetic points to our quest for simplicity in science, possibly deriving from a deconstructionist belief that everything can be equated to simplified smaller elements that make up a whole. Quine challenges Carnaps methodology as well as his philosophical system. To conclude, Quine notes that he understands the philosophical approach attempted by philosophers like Lewis, and Carnap, but does not think that it is a beneficial one. Total science, mathematical and natural and human, is similarly but more extremely underdetermined by experience. The edge of the system must be kept squared with experience(207). Carnaps constructed language is a scientific one, and since science is based on our experience, when Carnap attempts to encompass our world using his language with strict rules, he does an injustice to sciences close relationship to experience, making his language based on the rules of arithmetic instead. Finally, Quine points to Carnaps employment of pragmatism as one that comes up short, and does not justify the strict division between synthetic and analytic. Their pragmatism leaves off at the imagined boundary between the analytic and the synthetic. In repudiating such a boundary I espouse a more thorough pragmatism(207). Quine feels that the division between synthetic and analytic has been too hastily assumed, and that a more thorough approach to the relationship would be helpful. He believes that the boundary between analytic and synthetic is too harshly drawn, and that the difference is only in degrees. He asks Carnap to suppress his foundations in our traditional scientific method and suggests that sometimes it is not always pragmatism that shapes our perception.

Overview Of Cooling System Engineering Essay

Overview Of Cooling System Engineering Essay In order to reducing fuel consumption and meet the emission standards, many improvements has been made. The examples of the improvements are combustion strategies, fuel injection system, exhaust emission and fuel quality[1]. There are four possible sources of atmospheric pollution from the automobile. Without emission controls, a carburetor and fuel tank emits vapors, the crankcase emits blowby gases and the tailpipe emits exhaust gases that contain pollutants. The main regulated pollutant in engine exhaust are nitrogen oxides (NOx), carbon monoxide (CO), unburned hydrocarbon (HC) and smoke[2]. These air pollutants are harmful to human beings as well as plants and animals. The law now requires automotive manufacturers to install emission controls. Car that gives off excessive amount of air pollutants may not be allowed on the streets someday. Stronger laws limiting automotive air pollution and mandatory inspection and maintenance has been proposed. These laws are part of the government policy that cars must contribute as little as possible to the problem of air pollution. Each car already have three major systems for controlling pollutants from these sources that is positive crankcase ventilation (PVC), evaporative emission control and exhaust emission control. But in this study we want to focus more on engine cooling system and its effects to the emission reduction, fuel consumption and engine performance. Now, we will through about the components of engine cooling system and its functions. Engine cooling system is a system that responsible for cooling the engine by releasing heat through the cooling fins so that the carà ¢Ã¢â€š ¬Ã¢â€ž ¢s engine is not too hot or not too cold. This system helps to bring the engine up at to normal operating temperatures as quickly as possible and maintain the operating temperature for efficient function of the car engine. It is very important to keep the engine at its most operating temperature at all speeds and operating conditions. Burning fuel in the engine produces heat. Some of the heat must be taken away before it damages the engine parts. This is one of the jobs that performed by the cooling system. If the engine temperature is too low, fuel consumption will rise and if the temperature is too hot for too long, the engine will overheat. 1.2 TYPES OF COOLING SYSTEM There are two types of car cooling system which is the air cooling system and liquid cooling system. Air cooling system is a system that uses air as a cooling agent. It is commonly used in single cylinder engines such as motorcycles while liquid cooling system is known as the radiator system. It a system that uses liquid as a cooling agent and is used in a multi-cylinder engine such as cars and trucks. Radiator is the crucial components in the car cooling system. It ensures the engine is not overheating. Figure 1.1 : Cooling System Components [12] 1.3 COMPONENTS OF COOLING SYSTEM 1.3.1 WATER JACKET For operation of the cooling systems, it uses five basic parts or components to do the job in controlling the engine temperature that is water jackets, water pump, thermostat, radiator and fan. Water jackets are open spaces between the cylinder walls and the outside shell of the block and head. Coolant from the water pump flows first through the block water jackets. Then, the coolant flows up through the cylinder head water jackets and back to the radiator. 1.3.2 WATER PUMP Water pump usually known as impeller pumps. It is attached to the front of the engine and are driven by a belt from crankshaft pulley. The pump circulates as much as 28 390 L of coolant an hour. As the impeller rotates, the curved blades draw coolant from the bottom of the radiator. It forces the coolant from the pump outlet to the water jackets. The impeller shaft is supported on sealed bearings which never need lubrication. The seals prevent the coolant from leaking past the bearings. 1.3.3 RADIATOR Radiator is a heat exchanger that removes heat from engine coolant that passing through it. The heat transfer from the hot coolant to the cooler outside air. It has three main parts that is radiator core, inlet and outlet tanks. The core consists of set of tubes and set of fins that attached to the tubes. Figure 1.2 : Coolant Flow Inside Engine Cooling System [12]C:UsersFaisal Mamat.FaisalMamat-PCDesktopCapture.PNG 1.3.4 THERMOSTAT For thermostat, it is a heat operated valve that regulates the coolant temperatures. It does this by controlling the coolant flow from the engine to the radiator. The thermostat is in the coolant passage between the cylinder head and the radiator. The valve in thermostat stay open and close as coolant temperature changes. As long as the coolant temperature is below the thermostat set point, the thermostat remains closed. Once the temperature arrives at the set point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The passage to the radiator is closed when the engine is cold so the engine can warms up more quickly. Engine heat stays in the engine instead of being carried to the radiator. Figure 1.3 : Closed Position of Thermostat [12] Figure 1.4 : Open Position of Thermostat [12] 1.3.5 ELECTRIC FAN An electric fan is turned on by thermostatic switch only when needed. For example, it turns on when the coolant temperature reach 93 °C and turn off back the fan if the coolant drops below this temperature. But on vehicles with air conditioning, turning on the air conditioner bypass the thermostatic switch. The fans run all the time when air conditioner is on. The fan is controlled by electronic control module (ECM) in many vehicles with an electronic engine control system. 1.4 PROPERTIES OF COOLANT 1.4.1 TAP WATER Tap water is potable water supplied to a tap inside the household or workplace. The application of technologies involved in providing clean water to homes, businesses and public buildings is a major subfield of sanitary engineering. Specific chemical compounds are often added to tap water during the treatment process to adjust the pH or remove contaminants, as well as chlorine to kill biological toxins. The use of tap water adversely affect the car cooling system. Tap water contains magnesium and calcium ions that will form the yellow precipitate (rust) when the water becomes hot. The yellow precipitate will be attached to the car engine after long time period and this will reduce the absorption of heat from the engine. If this rust become denser, it can interfere the passage of cooling liquid in the car cooling system. 1.4.2 ETHYLENE GLYCOL (EG) Ethylene glycol is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure form, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is toxic, and ingestion can result in death. Ethylene glycol is produced from ethylene via the intermediate ethylene oxide. The major use of ethylene glycol is as a medium for convective heat transfer. For example, automobiles and liquid cooled computers. Pure ethylene glycol has a specific heat capacity about one half that of water. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. A 50/50 mix by mass has a specific heat capacity of about 0.75 BTU/lb F, thus requiring increased flow rates in same system comparisons with water. 1.5 FUEL Gasoline is a transparent, petroleum derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. Some gasoline also contain ethanol as an alternative fuel. A good gasoline quality should have : Proper volatility, which determines how easily the gasoline vaporizes. Resistance to spark knock or detonation. Oxidation inhibitors, which prevent formation of gum in the fuel system. Antirust agents, which prevent rusting of metal parts in the fuel system. Detergents, which keep help keep the carburetor or fuel injectors clean. Dye for identification, such as red eye which gives leaded gasoline a rust or orange colour. 1.5.1 VOLATILITY Volatility is the ease with which a gasoline vaporizes. Gasoline must vaporize quickly after it is mixed with air in the throttle body or intake manifold. Otherwise, drops of liquid gasoline enter the cylinder walls. This increases wear of the cylinder walls, pistons and rings. Gasoline that does not vaporize will not burn. It leaves the cylinder in the exhaust gas and pollutes the air. This wastes gasoline and reduces fuel economy. Volatility determines how quickly a gasoline can vaporizes. A high volatility gasoline can vaporizes quickly while a low volatility gasoline vaporizes slowly. Gasoline must have the right volatility for the climate in which it is used. 1.5.2 ANTIKNOCK QUALITY Antiknock is known as octane rating. It measure the gasoline ability to resist knock during combustion. The higher the octane rating, the greater the engines resistance to knock. The knocking in your engine occurs when the air fuel mixture detonates prematurely. Since it is the gasoline vapor that ignites, the air fuel mixture must be correct to burn smoothly. Some of the problems associated with knock are overheating of engine parts such as valves, pistons and spark plugs. 1.6 EMISSION Then we will go for the explanation about the combustion in the engine and how it resulting emission. Automotive fuels such as gasoline are made mostly of two elements that hydrogen and carbon. They have chemical symbols H and C. This type of fuel is hydrocarbon (HC). During complete combustion in the engine, these two elements unite with other element, the gas oxygen. Oxygen, usually in the form of free oxygen (O2), makes up about 20 percent of the earth atmosphere. This is the air that we breathe. During combustion process, each atom of oxygen will unites with two hydrogen atoms. Each carbon atom unites with two oxygen atoms. Oxygen uniting with hydrogen produces water (H2O). Carbon uniting with oxygen produces gas carbon dioxide (CO2). During combustion, the burning of air fuel mixture in the engine cylinder may reach 2200oC or higher. This high temperature produces pressure in the engine that makes it run and produces power. With perfect combustion, all the hydrogen and carbon in gasoline would unite with the oxygen. The exhaust would contain only harmless H2O and CO2. But combustion is not perfect in the engine. Some of the gasoline (HC) does not burn. Also, some of it only partly burns. This produces carbon monoxide (CO). This lack of oxygen prevents the formation of carbon dioxide. The unburned gasoline and partly burned gasoline (CO) exit from the engine through the tailpipe. Once in the air, it will cause atmospheric pollution. Another group of atmospheric pollutants th e engine is nitrogen oxide (NOx). About 80 percent of the atmosphere is gas nitrogen (N). High temperatures in the combustion chamber cause some of the nitrogen and oxygen to unite and form nitrogen oxide (NOx). 1.7 PROBLEM STATEMENT Nowadays the rate of fuel consumption currently going on throughout the world is quite alarming. Fuel consumption and emission rates are off the chart. This will give negative impact to the environment and increase the pollution rate. Basically the power to move a motor vehicle comes from the burning of air fuel mixture in an engine. Air pollutants from vehicles comes from the products of this combustion process. With perfect combustion process, the emission would be water (H2O) and carbon dioxide (CO2). Both of these are harmless gases. But combustion is not perfect in an engine. Some of the gasoline (HC) does not burn and some of it only partly burns. This produces carbon monoxide (CO) and nitrogen oxide (NOx). Both of these gases are air pollutants and breathing polluted air is very bad for human and animals. Then the demand for low cost car from customer that has good performance with low fuel consumption and emission also increase. Usually car that has good performance will have high fuel consumption and emission rate. In order to solve these problems, the study about engine cooling system and its effects towards engine performance, fuel consumption and emission reduction will be conducted. Two types of liquid cooling such as tap water and ethylene glycol will be used and its temperature will be checked in order to investigate the influenced to these 3 outputs. 1.8 OBJECTIVES OF THE RESEARCH To study the effect of engine cooling system and its components to the engine performance, fuel consumption and emission. To investigate the influence of percentage of ethylene glycol in the coolant and coolant temperature set point to the engine performance, fuel usage and emission rate. 1.9 SCOPE OF THE RESEARCH The scope of this researched is mainly about the variations percentage of coolant (ethylene glycol) mixed with water and its temperature effects towards engine performance, fuel consumption and emission. The percentage that will be used for ethylene glycol are 30%, 50% and 70%. For every percentage, the coolant temperature set point will be controlled using two kind of thermostat with temperature set point 80oC and 100oC. The increasing temperature in cylinder block by increasing the coolant temperature results in fuel savings and emission reduction. Boiling Point Ethylene Glycol solution (% by volume) 0 10 20 30 40 50 60 70 80 90 100 Temperature F 212 214 216 220 220 225 232 245 260 288 386 C 100 101.1 102.2 104.4 104.4 107.2 111.1 118 127 142 197 Table 1.1 : Boiling Point of Ethylene Glycol Solutions [13] Car model that will be used is Perodua Kancil 660cc (4 stroke and 3 cylinder). Then for the fuel, petrol RON 95 will be used. Three test will be conducted in investigate the engine performance, fuel consumption and emission rate. The test for engine performance is dynamometer test. A dynamometer is a device that is used for measuring force, moment of force (torque), and power. For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (RPM). For the fuel consumption, we will conducted a fuel test by using a new tank provided by automotive lab. Unit to measure the fuel test is in liter/km. To measuring the emission rate, gas analyzer is used and the measurement unit is in concentration of gas which is parts per million (ppm). 1.10 SIGNIFICANT OF THE RESEARCH This study will give better understanding and exposure about the operation in the engine cooling system and how it will effects the engine performance, fuel consumption and emission. Reducing the fuel expenses by car users as the rate of fuel consumption reduced. The expected output to reducing the emission will result in increased the air quality that is harmful to humans. It also will lead in reducing the air pollution rate and provide more safer environment for people. The low cost car with good performance and low on fuel and emission rate also will be develop. 2.0 LITERATURE REVIEW 2.1 COOLING SYSTEM OPERATION A huge amount of heat is generated in the internal combustion engines. It is created when the air fuel mixture is ignited inside the combustion chamber. The explosion that occur will causes the piston to be forced down inside the cylinder, levering the connecting rods and turning the crankshaft. The temperatures of the metal parts around the cylinder can exceed 2500oC. To prevent the components such as engine oil, cylinder walls, pistons, and valves from overheating, it is necessary to effectively dispose the heat. Approximately 30% of heat in the combustion process is lost into the atmosphere through the exhaust system, 35% is converted into power to drive the vehicle and the remaining 35% lost as heat through the cylinder walls [9]. Water pump is attached at the front of the engine and driven by a belt from crankshaft pulley. The impeller rotates and the curved blades draw liquid cooling from the bottom of the radiator and force it to flow through pump outlets and water jackets. The liquid cooling will flow through passageways in the engine block and cylinder head. Temperature in the combustion chamber can around 2500oC, so cooling around this area is critical to prevent overheat. The areas around exhaust valve are especially crucial and almost all space inside the cylinder head around the valve that is not needed for structure filled with coolant. But when the engine is still cold, thermostat still close and the liquid cooling is circulated back to the engine. By closing the passage through radiator when engine is cold, the engine warms up more quickly. Engine heat stays in the engine instead of being carried to the radiator. This shortens warms up time, wastes less fuel and reduces exhaust emissions [3]. After engine already heat up, the thermostat keeps the engine running at a higher temperature than it would without a thermostat. The higher operating temperature improves engines efficiency and reduces exhaust emissions [3]. 2.1.1 EFFECT OF RADIATOR A radiator usually known as heat exchanger. The hot coolant that flows through it will transfer the heat by the air blown through the aluminium fins by fan. Nowadays modern cars use aluminium radiators. It usually made by brazing thin aluminium fins to flattened aluminium tubes. Flow of the coolant is from inlet to the outlet through many tubes that mounted in parallel arrangement. These fins will conduct the heat from the coolant inside the tubes and transfer it through the air that flowing through the radiator.[1] A type of fin is inserted into the tube called turbulator. Its function is to increases the turbulence of the fluid flowing through the tubes. If the flowing of the fluid through the tubes is smooth, only the fluid that touching the tubes would be cool directly. The amount of heat transferred from the fluid to the tubes depends on the difference in the temperature between the tube and the fluid touching it. Therefore, less heat will be transferred if the fluid that is in contact with the tube cools down quickly. To prevent that, turbulence is created inside the tube and all of fluid mixes together. Keeping the temperature of the fluid touching the tubes up so that more heat can be extracted and all of the fluid inside the tube is used effectively. 2.1.2 EFFECT OF RADIATOR FAN The function of radiator fan is to draw the air towards the radiator and helps to cool the hot coolant that flowing through the tubes. It usually has four or more blades that spin rapidly to provide sufficient air to that would cool the engine. The fan will be mounted between the radiator and the engine so that the air can easily flowing through the radiator. There are also additional fan in front of the radiator in some cars in order to draw more cool air to the engine especially when vehicle is not moving fast enough, very little cool air reaches the radiator and the engine is not cooled properly. 2.1.3 EFFECT OF PRESSURE CAP The radiator cap or also known as pressure cap actually increases the boiling point of your coolant by about 25oC. The cap is a pressure release valve and usually is set to 15 psi. When the coolant is placed under pressure, its boiling point will increase. As the engine running, the cooling system will be heated up and increase the pressure. The only place where the pressure can escape is at the pressure cap. Therefore, the setting of the spring on the cap determines the maximum pressure in the cooling system. If the pressure reaches 15 psi, it will push the valve open and allowing the coolant to escape from the cooling system. The flowing of the coolant is from overflow tube to into the bottom of the overflow tank. This kind of arrangement will keep air out of the system. After the radiator is already cools back down, a vacuum is created in the cooling system that pulls open another spring loaded valve while sucking the water back in from the bottom of the overflow tank to replace the water that was expelled. 2.1.4 EFFECT OF WATER PUMP Water pumps are impeller pumps. They attached to the front of the engine and driven by a belt from the crankshaft pulley. As the impeller rotates, the curved blades draw coolant from the bottom of the radiator[3]. The water pump only thrust to drive the circular flow of the coolant within the engine cooling system, so the inlet is the point of lowest pressure in the system and the exit point is the highest pressure. The pressure drops sharply at the inlet/outlet of the water pump during the operational of the water engines and this pressure drop will vary in proportion to the rotational speed. Water pumps in engines are prone to cavitation and air bubbles are likely to permeate in to antifreeze and will severely reducing the performance, reliability and service life of the engines[6]. Cavitation means the cavities or bubbles are forming in the liquid that have been are pumping. These cavities form at the low pressure or suction side of the pump. For the well design engine cooling sys tem, cavitation is less likely to take occur as the temperature of the coolant declines. But when the cavitation temperature is reached, the pressure of the water pumps drops abruptly and all the cooling system loses its functionality. 2.1.5 EFFECT OF THERMOSTAT The main function of the thermostat is to allow the engine to heat up quickly and keep it at its efficient temperature. It control this by regulating the amount of water that goes through the radiator. The coolant in the cooling system starts to initiate by picking up heat at the water jackets. In the coolant circuit, the pressure gradient exist and causing the hot coolant flows out from the engine to the radiator or to coolant bypass passage [2]. Once the temperatures of the coolant rises to 80oC, the thermostat starts to open. Different thermostat open at different temperatures and allowing fluid to flow through the radiator. The secret of the thermostat lies in the small cylinder located on the engine side of the device. Actually this cylinder is filled with wax that starts to melt at temperatures 80oC (depends on the thermostat). Then, a rod that is connected to the valve press into this wax. As the wax melts. It will expands and pushing the rod out of the cylinder and opening th e valve. 2.2 EFFECT OF COOLANT Coolant is the mixture of antifreeze and water in the cooling system. The commonly used antifreeze is Ethylene Glycol. This coolant will circulate through the cooling system. It will remove the waste heat from the engine and delivers the heat through the radiator hose to the radiator. It is not recommended to use only water as a liquid cooling because it would freeze if the temperature drop below 0oC. This would stop the circulation and the engine would overheat. As the water would expand 9% as it freezes, it would crack the cylinder block and head, split the radiator [3]. By controlling the engine cooling system in a flexible way as compare to the conventional cooling system, it will improve the fuel consumption rate of spark ignition (SI) engines [11]. It is known from the cold start research that the coolant and inlet charge temperature are key parameters to reduce pollutant emissions and guarantee smooth engine operation. Cold start experiment were performed with coolant temperatures of 15oC and 80oC. In the steady state operation reached after the start, the piston surface temperature was respectively 110oC and 150oC. The HC emissions were 25% lower and the NOx emissions 7% higher with the higher coolant temperature. It seems to indicate that there is an influence of the coolant temperature on the emissions through the cylinder wall temperatures [5]. In the search for greater fuel economy and reduced emission output, the engine cooling system is being targeted for further improvements to engine performance through its effects on engine frictional losses. Fuel economy improvements from the changes to the engine cooling system are derived mainly from reduced engine frictional losses with increased oil temperature by raising the engine operating temperature indirectly through the step increase in the coolant temperature. Hydrocarbon (HC) and carbon monoxide (CO) output are also shown to decrease with the increase in operating temperature [7]. There are also suggestion that higher cylinder block temperatures will reduce the frictional losses with the piston and ring pack and will lead to reducing fuel consumption [10]. But the increasing of operating temperature has a negative effect on nitrogen oxide (NOx) output as the formation of NOx in the combustion chamber can be highly sensitive to temperature changes [7]. There are some previous works in the engine cooling area focuses on to the fuel economy benefit to IC engines through the reduction engine frictional losses by raising the coolant temperature. As the coolant temperature increases, the cylinder block wall temperaturs also increases and will result in reducing the HC emissions [11]. It concentrates mainly on gasoline engines where oil temperature is relatively lower and the tailpipe emissions are HC and CO. Fuel efficiency improvements about 10% are achieved in part load conditions by raising coolant temperature [7]. METHODOLOGY 3.1 INTRODUCTION In this chapter, we will discuss about the procedures and entire activities to carry out in this whole project. The flow chart below will describe the steps that should be followed during this project. Basically there are 3 test that will be conducted that is dynamometer test, fuel test and emission test. 3.2 FLOW CHART Part Selection Select the type of liquid cooling and thermostat that will be used. Preparation and Setup Select the type of liquid cooling and thermostat that will be used. Run the experiment The experiment will be conducted to the conventional and modified cooling system. Emission Test Fuel Test Dynamometer Test Data Analysis TYPES OF METHODS 3.3.1 DYNAMOMETER TEST Dynamometer is actually a device use to measuring force, moment of force (torque) and power produced by an engine or motor. We can see the example from the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (RPM). Nowadays dyno test become more easier to operate with the advance of the modern computer and produce more accurate results. A dyno that paired with the computer will display the power rating of a given machine as a figure below. C:UsersFaisal Mamat.FaisalMamat-PCDesktopdynamometer-test-2.1-800800.jpg Figure 3.1 : Example Graph of Dynamometer Test Actually dyno test is used for various applications but the most common one is automobile testing. Automobile manufacturers will measure the performance of a car or truck in order to market its power. Sports car will modified their vehicles with aftermarket parts in order to achieve higher power output and then run the dyno test to evaluate their modifications. Dyno tests can be run in a couple of different ways which is chassis and engine dyno. When running a chassis dyno test, the vehicle to be tested is driven onto the dyno platform that simulates resistance through the use of automated wheels. For an engine dyno test, the engine to be tested is mounted to the dyno device. These different methods produce different measurements such as brake horse power and torque from a chassis dyno and flywheel horse power and torque from an engine dyno. Power is often lost through the drive train of a vehicle so the brake measurement will typically less than the flywheel measurement. The model that will be used for dynamometer testing is Dynapack 3000. The components of Dynapack 3000 consists of computer, sensors hub adaptors controller and power absorption units. This test is a bit from other dyno test because of the elimination of the tire to roller interface on a conventional roller dyno. It eliminates this variable by using a hub adaptor that provides a direct coupling to our power absorption units. There will be no tire slip, no rolling resistance and no chance of the vehicle coming off from the dyno at high speeds. For the theory of operation. Firstly the hubs of the vehicle are directly attached to hydraulic pumps. A variable load can be applied with all of the potential holding power that hydraulic possess. Figure below show that the wheels are removed from the vehicle and the variable fit hub adaptors are bolted to the vehicle axle. The hub adaptor is then directly attached to a hydraulic absorption unit.

The problem with the existing tank is the fuel consumption cannot be measured correctly. The new fuel tank will be connected using the hose from the fuel pump to the series of injectors at cylinder head. Gasoline or RON 95 will used in this fuel test. The example for the new fuel tank is shown in figure below and the fuel pump is already attached on top of it.

It is done to control the speed of the engine to get the accurate result of the fuel consumption without affected by the changing of gear on each test. The RPM and gears can be referred in the table below. Gear RPM Distance (km) 1 3000 2 3000 3 3000 4 4000 Table 3.1 : RPM for each of the gear 3.3.3 EMISSION TEST Hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxide (NOx) are measured in parts per million (ppm). For this emission test, the device that will be used is the gas analyzer 95/3. The gun of this device will be placed into the tailpipe to measure the exhaust rate. The data will be taken during the various RPM that already been set up which is 2000 rpm, 3000 rpm and 4000 rpm. The result of this test will be recorded in this device.

Spousal Testamony against an accused :: essays research papers fc

Dating back to the 16th century, spouses were not deemed to be competent to testify evidence against their spouse. The reasons were a lot simpler than they are today. Anyone with a perceived interest in litigation was deemed to be biased and therefore unfit to testify. Under common law spouses are considered to be one and the same. Since the 16th century the issue of spouse’s and their ability to give evidence against their partners has become more and more complicated. Modern day courts rely more on preserving the sanctity of the marriage than preserving the incompetence standard.   Ã‚  Ã‚  Ã‚  Ã‚  The ability to block spousal testimony does not however apply to all couples under the law. Those in common law relationships are not considered to be one and the same and these spouses’s are able to give testimony about events that occurred during the relationship. Ultimately, because the issue falls under common law the question of whether a husband or wife to can be compelled to give evidence against there spouse was at the justices discretion. Most justices are more likely to compel spousal testimony in cases of violence and domestic abuse. The majority of these offences are committed on a one on one basis with either no one to witness the abuse, or a child incapable of being called as a witness. The testimony evidence of the spouse is often the only proof that an offence occurred. In R. v. McGinty, Justice McLachlin concluded that competence included compellability and added a new policy dimension to the analysis. She observed: â€Å"policy interests favoured compelling testimony in cases of domestic violence. Competence without compellability would more likely [contribute to] family discord than prevent it.† In the matter of appearance, she noted that: â€Å"fair-minded persons generally find it abhorrent that persons who commit crimes go un-prosecuted. The state’s duty to protect the safety of its citizens, underlies the testimonial competence in cases of violence against a spouse, also dictates that the spouse be complellable.† Fundamentally the main factors facing a Justice in their decision is the matter of public safety and the harmony of the marriage. Compelling a spouse to testify against their partner is in direct conflict with that ideology. Therefore divorced or legally separated couples do not fall under this category. In R. v. Bailey it was determined that spousal incompetence does not survive divorce. Justice Morden observed that: â€Å"The modern policy justification for the rule in question is that is supports marital harmony.

Roger Maris :: essays research papers

Roger Maris is probably one of baseball’s most misunderstood baseball heroes. Still now after almost 40 years Maris has still not achieved his rightful place in baseball history, the Baseball Hall of Fame. Roger Maris has had a picture-perfect life starting in Hibbing, Minnesota to where he grew up in Fargo, North Dakota. His young life was marked with athleticism. He excelled at many sports not just baseball. Roger was affluent in football and track among others. His baseball career began with the Cleveland Indians in 1957 and he was traded to the Kansas City Athletics in 1958. In 1966, he was traded to the St. Louis Cardinals. Maris retired from baseball following the 1968 season. Roger Maris was born in the small town of Hibbing, Minnesota. He only lived there for a few years until he moved to Grand Forks, North Dakota, where he stayed until he was ten. Maris began to realize his talent for athletics during those years. His father remembered that Roger could always play sports better than all of the other kids. More specifically he recalls that no other kid in the neighborhood could begin to match the distance in which Roger could hit the baseball. He was one of the fastest members of the track team. He was also prominent on the basketball and football teams. He was a local champion of stickball, being the only one who could hit the ball nearly 200 yards. Rogers’ family then moved to Fargo, North Dakota. His athletic skills were never used to their potential by the school so he changed high schools to Shanley high school where he was more appreciated. His football, track and basketball talents were used to the maximum potential and Roger gained a local fame.   Ã‚  Ã‚  Ã‚  Ã‚  Like many other baseball stars, Roger Maris began his career in American Legion baseball. He played outfield and he also pitched. In this league he was named the Most Valuable Player on the North Dakota championship team in 1950. After graduation Roger had to choose between football and baseball. It was a hard choice for him and he could go far in either sport. Thank goodness for baseball he chose it. He briefly considered college but he turned down the University of Oklahoma and numerous other colleges that made him offers.   Ã‚  Ã‚  Ã‚  Ã‚  A scout report that was made by Frank Fahey in 1950 resurfaced in 1961 and as a result of this the Cleveland Indians asked him to a tryout camp.
