Great Expectation Essay

Compare the filming techniques used in Pip’s first meeting with Miss Havisham with two adaptations of Charles Dickens’s â€Å"Great Expectations†Ã‚  The two film clips that this essay will be based on, and comparing, is a version by Julian Jarrold which appeared on TV screens in 1999 and a much older cinema appearance by David Lean from 1946. The first noticeable difference is that the earlier film is played in black and white and therefore has certain lighting limitations and, as a result of technological disadvantages, has limited camera shot availability. However, there are a number of useful factors available for analysis. Both films attempt to build up a sense of mystery and increasing tension all the way through the scenes and the task in hand is to focus in on all the different types of filming techniques used to do so. On the whole, the 1999 version is darker than the 1946 edition and this increases the tension factor. Each scene takes us from Pip entering Miss Havisham’s room to when he leaves and incorporates all of the insults and belittling from Miss Havisham and Estella, although even this is played differently in the two films; David Lean makes very obvious insults as though Estella is actually telling him he is lower than her yet in Jarrold’s version Estella either insults Pip to Miss Havisham or to herself in an undertone. There are six main techniques used by each director which this essay will analyse, they are: shot types and framing-how each camera shot affects the â€Å"mood† of the scene, camera angles and lens movement-how the camera is positioned and what bearing that has on the scene, editing, music and sound effects-the backing sounds and its effect on the viewer, costumes-what each actor is wearing and what it does for the characters personality/appearance, lighting and visual effects-how the light and dark areas of the screen portray different ideas. Firstly, there are a few similarities between both scene’s Shot types and framing/Camera angles and lens movements/Editing. The first is that both incorporate a long shot as Pip enters to show the huge room in front of him and show that this room really is intimidating as Pip looks tiny compared to the huge open space ahead. Secondly, both films show Pips reaction as a close up shot after the insults from Estella, this gives the viewer a real sense of pity for Pip and shows us what exactly is going through his mind at the time. The final similarity is as the game of cards unfolds, both films fade into the game to show a passing of time and both use an extreme close up to show us what is happening and, Miss Havisham is sat high on a chair in the middle, with Pip and Estella on the floor either side, with a medium shot, making Miss Havisham look very dominant and the children look almost patronised. The 1999 version has a lengthy amount of time when Pip is wondering around the room looking at certain objects, building up mystery and tension, which Jarrold misses out and skips from Pip entering straight to his conversation with Miss Havisham. This â€Å"added† section has a mixture of medium close ups, close ups and extreme close ups, but all the way through the shots are positioned a bit higher than Pip so it gives the audience the idea that somebody has a watchful eye on him, and this, to a certain extent, is almost creepy, certainly builds up mystery and also borderlines on scary. For example, when Pip is walking past the dummies the camera is high up so it is as though the viewers are looking through Miss Havisham’s eyes. The other main camera uses are when Pip sees Miss Havisham in the mirror, she looks virtually ghost like and it is almost scary, but just before she appears, its looks again as though he is being watched, and as Miss Havisham waves her arm to tell Pip to play, there is a close up of her arm to show her dominance and shortly after a close up of Pip’s face to show the confused reaction. This section of the scene is very clever camera work by Jarrold, and really does freak the audience out. Both films use shot types, framing, camera angles, lens movement and editing differently, but there a number of specific differences between the two. When the two films join back up, there are many different camera uses and consequences of such. In the 1946 version, there is a long shot as Pip walks up to Miss Havisham and a medium close up as they talk to one-another and as Pip advances further, the camera moves in an arc to keep him and Miss Havisham on the picture at the same time. When they are closer, it allows an even closer shot than before of their faces and therefore portrays both expressions and the reactions to each others expressions individually. An addition to this version of â€Å"Great Expectations† is how the camera zooms in on a cobweb covered bible to show the lost faith of Miss Havisham, and explain to the audience that something terrible has happened earlier in her life to make her do so. A two shot of Miss Havisham and Pip is on screen, and, as Estella joins the camera â€Å"slides† horizontally to follow her in. As Estella whispers in Miss Havisham’s ear there is a two shot to portray Miss Havisham’s expression. When Miss Havisham asks Pip his opinion of Estella he is made to whisper it in her ear but as he does so there is a medium close up showing all three expressions at the same time, i.e. Pip’s horror as Miss Havisham tells Estella what he has just said and Estella’s delight of hearing such approving words. As Pip approaches the gate to go home, there is another fade in to show more time has passed by. This can be compared with the 1999 version which has a much briefer conversation between Pip and Miss Havisham as much time is spent when Pip walks around, but, when Pip is whispering about Estella, the camera zooms in on Estella’s face to show her reaction after being praised by Pip. Finally, when Pip and Miss Havisham are talking, there is a two shot of them to show each reaction as each person says something.

Examine Sheriff’s presentation of Stanhope in Act One in Journey’s End

In Act One of Sheriff’s ‘Journey’s End’ we see Captain Stanhope presented as a highly respected individual by all members of the rank, who has been affected immensely psychologically by the war.We see Stanhope being respected throughout Act One, which can be seen in the beginning of the play where we see Osborne reacting in a defensive and protective way of Stanhope, saying that â€Å"He’s a long way the best company commander we’ve got† to Hardy on page 4 where we learn of Stanhope’s excessive drinking which makes the audience unsure of Stanhope as a character as Sheriff introduces us to this problem before we have met him, which instantly gives us a poor first impression of Stanhope.Sheriff then builds Stanhope’s character and the audience begin to realise that the effect of war has taken its toll on Stanhope, who we learn is a hardworking, young commander who is struggling with the pressures of the war and uses whiskey to help him get through. It is evident that Stanhope is good at commanding the company, as Osborne states â€Å"You’ve done longer than any man in the battalion. It’s time you went away for a rest.It’s due to you† on page 27, depicting that Stanhope has worked extremely hard in the last three years and should be proud with his achievements instead of being ashamed of himself because of what he has turned into. Osborne is a trustworthy character who Stanhope relies on and is a true friend. We also see Stanhope respected by Raleigh, a young boy who knew Stanhope personally before the war. Stanhope was Raleigh’s inspiration to join the army, saying that he was â€Å"frightfully keen to get into Dennis’s regiment† to Osborne on page 12.He also describes his friend as â€Å"splendid† and describes them as â€Å"terrific pals. † Stanhope had such an effect on Raleigh when they were at school together, and Stanhope even admits that he is Raleigh’s â€Å"hero† to Osborne on page 26. We also see in this scene that Stanhope has realised even more so with Raleigh’s arrival his change and deterioration with his personality in the last three years since the war began, saying â€Å"as long as the hero’s a hero† which he no longer thinks of himself as due to this drastic change.We also see in this scene Stanhope confide in Osborne, explaining that Raleigh’s sister â€Å"doesn’t know. She thinks I’m a wonderful chap – commanding a company† portraying his disappointment in himself and how he feels as if he would let down his love if she knew the truth. He seems extremely passionate towards Raleigh’s sister as he explains that he â€Å"couldn’t bear to meet her, in case she realised† the person he has become and becomes annoyed with Raleigh as he calls him a â€Å"little prig† when he believes he will no longer be able to return to Raleigh’s sister once the war is over.Here we see a vulnerable and ashamed character, which is portrayed by Sheriff as he says â€Å"if I went up those steps into the front line – without being doped with whiskey – I’d go mad with fright. † This conveys the necessity for Stanhope to drink and that he would not be able to command the company as successfully as he does without having had whiskey.Osborne warns Raleigh on page 13, explaining to him â€Å"you mustn’t expect to find him – quite the same† and how the war â€Å"tells on a man – rather badly† portraying the psychological effects of war and how there has been a complete change in Stanhope since joining the war. Raleigh remembers his hero as someone who was anti-alcohol, which he was before the war saying â€Å"the roof nearly blew off† when he caught some boys at school with a bottle of whiskey.This shows the desperation on Stanhope†™s behalf to cope with the war and has turned to alcohol for comfort, something that appears he was against three years earlier. Sheriff presents Stanhope as an individual trying to cope with the pressure of the war in Act One, who appears to have changed drastically since the war began, helping the audience understand the psychological effects soldiers due to the war; an issue to which they could possibly relate to as the war was a big part of their lives.

The Rising Cost of Healthcare Essay

Without a doubt healthcare costs are rising out of control. Not one of us are happy with the increases, but we have to understand what the reasons are for the increases in healthcare. American people look at their insurance bills, co-pays and drug costs, and do not understand why they continue to increase. The insured should consider all reasons behind the increase before getting upset. In 2004, employer health care premiums increased over 11 percent, four times more than the rate of inflation. In 2003, premiums rose 10.1 percent and in 1002 they rose 15 percent. Employee spending for coverage increased 126 percent between 2000 and 2004. These increases were lower than expected. The site to look up information on the cost of health care coverage and the breakdown on the cost is (National Coalition on Health Care, Facts on health care costs). Premiums have risen five times faster than workers’ wages, if medical spending continues to rise by just two percent more than a personâ €™s personal income, by 2040 Medicare and Medicaid will rise 8.4 percent of gross domestic product this year’s 15.6 percent by 2040, according to Congressional Budget Office projections. If all government programs stay at the same size relative to the economy, the budget will grow from 19.9 percent of GDP in 2003 to 27.1 percent by 2040, (http://www.cato.org/sites/cato.org/files/pubs/pdf/tbb-0306-15.pdf). There are huge impacts of the rising costs of healthcare. Many people cannot afford health insurance today and struggle to pay for their medical needs. Of the families that do have health coverage, 50 percent are concerned about having to pay more for the coverage in the future, while 42 percent fear they will not be able to afford coverage at all if the rate increase keep s going the way it is. This leads to believe one of the reasons for health care cost increases: cost sharing or cost shifting. When an individual or a family does not have insurance, and cannot or does not pay their medical bills, the cost of health care rises. Over years the American healthcare system has been plagued by the continuous rise of healthcare cost. These costs include but are not limited to insurance premiums, co-pays as well as prescription drugs. One of the significant reasons for the increase is that nowadays people are living longer lives than they once did and this gives higher rates to contracting chronic diseases or developing life threatening injuries, this cause the United States healthcare system to suffer a finical  crisis. The three major parts to industries health care sector are as follows: the healthcare service industry consisting of providers such as medical practices, hospitals, clinics, nursing homes, and home health care agencies, next is the healthcare insurance industry consisting of both government programs such as Medicare and commercial insurers, and last is the managed healthcare industry consisting of organizations such as health maintenance organization (HMO’s) that incorporate both insurance and provider functions. Citizens of the United States are currently spending up to 15 percent of the income expenditures on healthcare. It has been estimated that the expenditures are likely to rise to about 29 percent of gross domestic product by the year 2040. The Medicare insurance program that was created in the mid-1960’s to cover the elderly that is funded by the payroll system is costing more than $5,000 per enrollee, a national cost of more than $200 billion annually. Projected cost for the Medicare will rise rapidly from 2.5 percent to 5.5 in 2030. For HMO’s they often emphasize their ability to contain costs through oversight of physician’s decisions or by implementation of capped payment scheme that aligns physician’s incentives with those of the healthcare plan. HMO’s do have lower hospitalization than traditional healthcare providers. Some people also argue that the increasing use of managed care generates positive externalities that benefit consumers enrolled in non HMO health plans. This argument typically invokes some notion of market discipline, arguing that traditional insures or healthcare providers will have to lower premiums to remain viable in a health insurance market. It may be difficult to measure the effect of HMO participation on spending and outcomes because enrollment in managed care plans often voluntary, and those who choose to enroll are likely to differ in unobservable ways from those who do not. Using data on 300,000 welfare recipients the average effect of the mandate is to increase spending by 12%. This increase may be due to higher payments to providers, higher administrative costs, the inclusion of normal level of profit for the HMO’s, or a mark-up of bids above cost. Check out this site that goes deeper into the HMO and the reason of increase to healthcare cost at; (http://www.nber.org/bah/winter03/w9091.html). Looking at healthcare outcomes it is looking like switching to a HMO does not improve the efficiency of the Medicaid program because they lead to substantial spending  increases with no demonstrable quality improvements.

Conventional Vs. Organic Food Essay Example | Topics and Well Written Essays - 500 words

Conventional Vs. Organic Food - Essay Example One of the dangers of feeding on conventional food is the accumulation of dangerous chemicals in the body. According to Geary (2012), the chemicals used in inorganic fertilizers that are in turn used to bring up the conventional plants later on accumulate in our bodies after we feed on these foods. This later results into health problems such as obesity, development of cancer and stomach upsets among others. An easier way to avoid this is to stick to the conventional foods that are easy to grow and take care of. Another danger of feeding on conventional food is the fact that such food contains less nutritional value when compared to the organic food. According to Geary (2012), the chemicals used in cultivating the conventional crops reasons hasten their growth leading to unsustainable development of roots that prevents the absorption of adequate minerals. As such, when taken this way, little nutrients are taken in leading to poor health among the users of such food. The reasons given by people to warrant their usage of conventional food rather than the organic is that the conventional food is cheaper. As Geary (2012) argues out, this can be dealt with effectively if all people were to shift to organic food. The main reason as to why the price of organic food goes high is the limited market available which forces farmers to sell their products at prices which are a bit higher in order to avoid the imminent losses. However, if all people were to cultivate or buy organic food.

De Beers and US Anti Trust Law Case Study Example | Topics and Well Written Essays - 750 words

De Beers and US Anti Trust Law - Case Study Example With the discovery of large mines in South Africa, the diamond availability in the world market suddenly reached a high. In order to ensure that the prices of the diamond in the market are maintained, the supplies had to be limited. The miners in South Africa which was the lead producer of diamonds, started working together and created a 'cartel' that would discuss and decide the price of diamonds in the world market. This cartel was formed with De Beers in the lead and they coordinated the entire operation of forming this initial syndicate that would canalize and fix the supplies of diamonds in the world market. This also ensured that every body in the trade benefited because it maintained the price of the diamond in the world market without allowing it to fall or rise phenomenally. Once the diamond mines in other locations of the world were discovered, the South African control over the world market with respect to the supplies of the diamond mines came down. More mines in Angola, Russia, Congo and Zaire started to dominate the world market and the South African share in the market came down to 17%. However, De Beers by enforcing clear commercial and economic control on the market could bring these people also under control and ensured that the price of diamonds does not fall and continued to rise or stabilise even when the supplies of diamonds kept rising. This meant that De Beers had to buy out from the market some of the diamonds that was available to bring stability to the pricing. This resulted in a large stock pile for De Beers. The company resorted to both buying as well as selling of diamonds in order to bring down the prices or raise the prices as the need may be. This ensured diamond price was under control and the miners did not suffer. De Beers and the US Government De Beers has been a practising monopoly. They tended to control the price of the diamond market and this meant that they violate the US Antitrust law and its governing principles. De Beers was violating every one of the Anti-trust law principle except for the consumer protection which De Beers says it covers. But then, even that would be under question on analysis. US Diamond Dealers mostly dealt with the buyers of De Beers diamonds. The identity of the diamonds is lost once they reach the coast of US. Though the diamonds are not known to have originated from De Beers, the company as a brand was very well known. The US government and its Department of Justice were also aware of the violations of De Beers and they have taken multitude of steps to bring them under the book but these are yet to materialise. The relationship with the diamond traders in US and that of the government is certainly not one for long and sustained relationship. It has to be direct and legal to be sustainable. In order to do this, either the company should change its method of operation or change the law to accommodate such a change. De Beers, the Illegal trade and the US Market The structure created by the anti-trust law is in line with the thinking of the greatest minds on economics. In addition to that, any violation of the basic principle of capitalist and free economics would only lead to the decay of the structure so carefully erected. De Beers is a violator

The ecffect of 1080 use in new zealand forest management Literature review

The ecffect of 1080 use in new zealand forest management - Literature review Example These conditions made it possible for possum s to thrive, with estimates placing their numbers to about 60-70 million in the 1980s (Montague et al, 2000). A number of issues have arisen since the introduction of possums in New Zealand, one of them being the resultant competition for food resources with other animals. Due to their large numbers, they consume plenty of native plants and animal species in the New Zealand forests and suburban areas. They prey on birds, lizards and insects, feeding on their young ones and eggs. They can also carry and transmit the Bovine Tuberculosis disease, bringing about health concerns for humans. In 1947, the government of New Zealand officially recognized the Australian brush-tailed possum as a pest. The National Possums Control Agencies (NPC A) was formed to coordinate efforts of bringing the menace under control. Methods that have been devised and applied to control possums in New Zealand include hunting, using traps and poison. These methods are environmental free. They never cause any harm to other species. Despite the controversy surrounding some of the methods, efforts to control possums have been regarded as successful. The number of possums in New Zealand reduced to about 30 million according to figures submitted to the National Possum Control Agencies conference (Landcare Research, 2009). Sodium fluoroacetate, commonly known as 1080, is the most widely used poison against pests in New Zealand according to the Department of Conservation (2014). Not only does it eradicate possums, but also other pests like stoats and rats. Aerial application is, however, indiscriminate and kills other animals such as birds, reptiles, fish, insects, dogs, deer and pigs (PCE, 2011). As a consequence, the use of 1080 has been a contentious issue since its introduction in the 1950s. Concerns raised in opposition include the negative impact on the environment and the county s wildlife. Animal rights groups have protested what they

Accreditation of City College of San Francisco - Research Paper Example Besides that I have incorporated pathos since there is an element of persuasion in argumentation and what better way to persuade than to appeal through the emotions of your opposition. The use of pathos has been juxtaposed with the use of logos since the opposition is one of the high intellects. Juxtaposition, therefore, is my second rhetorical device. The largest community college in California seems to have landed itself in big trouble. It faces the daunting prospect of losing its accreditation, a decision that would mean no more financial aid for its students and possibly the closure of the institution itself. The reasons for these are mainly fiscal trouble and mismanagement. Evaluators are not happy with the way City College allocates its budget, nor with the fact that it has a very few administrative staff, most of which, is untrained. According to Roberts, 92% of City College’s budget is spent on salaries and benefits with retirement benefits spiraling out of control, much of its one-time working capital is used to fund operational expenses and has a small number of administrators who are too inexperienced to run a big institution such as City College (Roberts). The Accrediting Commission for Community and Junior Colleges has given its verdict based on these reasons, the President of the Commission, Barbara Beno said, â€Å"Only accredited colleges can receive public funding under state law. However, City Colleges failure to fix serious, long-standing problems of leadership and fiscal planning means that the accrediting commission could vote as early as next June to yank the schools all-important certification† (Asimov). Losing accreditation would therefore mean no more public funding for one of the largest institutions in California, no chance of financial aid for its 90000 students and the dire prospect of closure. In fact, City College will also not be able to transfer credits,

Music and Passion Essay Example | Topics and Well Written Essays - 750 words

Music and Passion - Essay Example According to (Carducci 311) the type of music an individual listens has a reflex action on the type of personality an individual develops. The unique thing about music is not just the beats and the tempo or the rhythm but the words that a song writer chooses to work with. The words involuntarily change the thoughts of the listener. As a person listens, they take in the meaning of the words and slowly make them part of their lives. In a greater way, one slowly starts to change their world view, their thoughts and eventually change their character. This is seen is where an individual starts to use the words that they heard in a song and this shapes their daily lives. (Carducci 123) says that lyrics of a song can great influence the thoughts of an individual in a subconscious state. Aristotle talked about music and its power to communicate the emotional states of humans as well as their character. According to (Williams 92) Aristotle says that music directly imitates the passions as well as states of the soul. An individual listening to a particular type of music they are likely to absorb the same passion and a long exposure to the music, they develop characters based in the same passions. Based on these understanding, then the music people listens to is contributing too many of issues in the society. If the type of music an individual listens to can shape their characters as well as passions, then it means that these effects will also be seen in human relationships, laws, psychological challenges such as depression as well as anger. People who mainly listen to these types of music tend to show high levels of openness to new experience, high verbal ability as well as emotional stability. These individuals also believe that they are highly intelligent and tolerant. Majority of them can champion liberal social ideals. Majority of them are political conservatives and they also tend to be

MPH522 - Public Health Law and Policy, Mod 3 Case Assignment Essay

MPH522 - Public Health Law and Policy, Mod 3 Case Assignment - Essay Example The Association of Dietary supplement manufacturers brought suit against the Food and Drug Administration stating that it did not have the right to require single dose packaging of iron supplements and nutritional supplements with iron in them. According to the Dietary Association this is not a case of possible adulteration and therefore does not fall into that jurisdiction for the FDA. The FDA, however, there were risks and one of those was poisoning as well as the possibility of adulteration and had required all of these drugs be packaged in single dose (Westlaw) The Association of Dietary supplement manufacturers felt that the FDA had overstepped its bounds in requiring this kind of packaging for dietary supplements and iron. It was much more expensive to do this and though the FDA had been given quite a lot of authority, this was not included. The courts eventually agreed with the Association of Dietary supplement manufacturers even though there had been many deaths related to the overdose of children with iron compounds from these supplements. This is an example of public health law that is outdated does not help but a policy might possibly have (Hall, 2003). Public health officials are tasked with protecting the public, taking whatever actions are necessary to protect health (Hall, 2003). It would seem then that the FDA was still in the right as they were protecting the health due to many deaths related to the use of these drugs by children and overdosage on iron which could be prevented with single dose packaging. The FDA felt it was their duty to protect under these circumstances and this writer believes that review of the literature would support that perspective. When we view public health law we should see the use of duty, power, and restraint (Gosten, 2001). One likes to believe that the restraint is common sense. Yet often, it appears, public health officials use the duty and power and forget to use common

M4A2- Program Evaluation Method - Essay Example The company uses web beacons to collect and provide data about users by clicking on banner graphics, then storing the information on remote server. They are efficient to track data across multiple domains (Boehm, 1997). The company uses â€Å"information system† which is a network of software and hardware used to collect create and distribute data. The information system used by organizations to capture, transmit, store and retrieve information for the benefit of controlling the performance of the business, and produce specific products and services for customers (Bolcer, 2009). The company’s goal is to ensure that the target growth is attained at the end of the stipulated period. The company’s mission is to bring data to the masses and making data-driven decision making a reality by building a sustainable data infrastructure and knowing where each team member fits in building an efficient organizational structure. Every serious business contains boundaries that are agreed upon by both parties, that is, stakeholders and the program evaluator. Successful business professionals constantly ask themselves â€Å"what can I do and not do about this problem†? .This is an ethical question which if not addressed by evaluators in their boundaries can lead to practical difficulties and ethical violations that can threaten the project. Stakeholders in the project include current and potential funders, community partners, professional colleagues and consumers. The stakeholders will be interested in hearing about the program to ensure they will use the evaluation results. The questions will arise out of the goals and objectives in the program description, planning and the stated needs of the stakeholders. These evaluation questions will provide the foundation and direction for the evaluation with the stakeholders. In designing questions the convergent

Jade figure of a hound Research Proposal Example | Topics and Well Written Essays - 500 words

Jade figure of a hound - Research Proposal Example The artwork is in three dimensional, and it is in the form of a small sculpture. For instance, the artwork is symbolic of the importance given to domestic animals in Ancient China. Michael Sullivan opined that, â€Å"To many people â€Å"Ming† means not painting-for only recently has Ming painting come to be appreciated outside China- but the decorative arts.† Besides, one cannot identify any sort of sharp edges on the artwork because the edges are round in shape. The artwork can be divided as: dog’s head, body, and legs. To be specific, the head is pointed backwards and this fills the viewer’s mind with enthusiasm. To be specific, the dog’s head (especially the eyes) is the focal point of the artwork because the dog is expecting something and looking backwards. The next element in the artwork is the dog’s body, and the same is symbolic of the importance of proportion in art. The next element is the legs, symbolic of warmth and peacefulness. In short, the proportionate alignment of artistic elements proves that the artwork was produced by an artist who is interested in observing animals, especially their shape and size. The artwork consists of curves, symbolic of the athletic shape of animals, especially among dogs and other domesticated animals. The overall size of the artwork is related to the normal size of a dog. One can see that the artist did not try to alter the natural colour of jade and the lines and curves on the artwork prove the same. To be specific, the artist made use of jade as a medium to produce his artwork.

Olympic Sport Essay Example for Free

Olympic Sport Essay Any athlete in training will always emphasize the importance of hard work during training and keeping a balanced nutritional diet in an effort to reach his maximum peak during competition. For an Olympic athlete in training, his diet will always spell the difference between winning or losing his sport. The reality of training for an Olympic sport such as swimming is that the speed of the swimmer does not depend on the food intake of the swimmer. What makes him skim through the water much faster is his physical training and physique. Proper diet and nutrition is what will give the body the energy to complete training sessions and become more efficient while performing the trained tasks. This is why a diet analysis is highly important when training a swimmer. The diet analysis is composed of two parts according to the usaswimming. org website: Diet analysis is comprised of two parts, needs and intake. Optimal nutrition is a matter of balance (nutrients-in versus nutrients-out). In other words, a swimmer’s intake of nutrients must match his/her output of nutrients during rest and exercise. In terms of energy (aka calories), if the needs are greater than the intake, the net result is weight loss. Conversely, if the needs are less than the intake, the net result is weight gain. Therefore, an athlete must always be focused on healthy eating and conscious of having to substitute lower fat foods for whole fat foods as well as reducing any snacks that will not contribute to keeping his energy level high. The athlete will best be served by loading up on whole grains, cereals, and legumes with at least 5 servings of fruits and vegetables in a day. His protein intake should be limited to lean meats, fish, and poultry. A typical diet for swimmer would be composed of the basic food groups but on a varying scale. For instance, Carbohydrates are used as the fuel of the body and therefore a swimmer should consume about 55-60% of his daily calories from grain and cereal products. Protein in the meantime builds the swimmers muscle tissues and other chemicals needed for body function. So protein intake would be recommended at about 15-20 % calories. Fat in the meantime is the transporter of the body. Swimmers will consume only 30% of fat calories while limiting the intake will result in a desirable fat consumption range for the athlete.

Impact of Internet Usage on the Academic Performance

Impact of Internet Usage on the Academic Performance INTRODUCTION Problem Statement: The impact of internet usage on the academic performance of adolescent students at St. Stephens College . Statement of Problem: The study investigates how students of St Stephens College are affected by the use of the internet. St. Stephens College, located in Princes Town, Trinidad is known as one of the highest ranked academic institutions in the country. The school comprises of approximately 750 students, most of which excel at their studies. Most, if not all of the students attending the school has had some contact with the internet which could have an effect on their academic performance. It is believed that the internet helps students to be more involved academically, therefore improving the quality of work done by the student. There is also the fact that students can misuse the internet, be it cyber bullying or being distracted by it, which can negatively impact on them. Purpose of Study: This study is geared towards determining if the use of the internet by students of St. Stephens College has impacted upon their academic performance and if so, how. Educational Value:  The information gained from this study can be used to re-assess the importance and significance of the use of the internet by students. The information can help to inform individuals of how to designate their time on the internet and also help promote proper use of the internet throughout various schools or even throughout the country. Research Questions: Is there a relationship between the use of the internet and academic performance of students? Have students become dependent on the internet? Has the use of the internet promote or hinder the academic performance of students? DEFINITION OF KEY TERMS Internet A global system of interconnected computer networks which bear a variety of information and services. Academic performance- How well a student is accomplishing his or her tasks and studies. Student A person studying to obtain a higher education LITERATURE REVIEW The internet is a global linking of devices that allow information transfer. The internet was established in the early 1960s by the U.S department of defence (Schneider, Evans and Pinard, 2006) for military purposes. It is a fact that the internet is one of the greatest advancement in the world of information technology as it has become a useful instrument that has fostered the process of making the world a global village. The Internet provides an environment in which millions of people participate and engage in the creation and exchange of information (Rose Fernlund, 1997). It allows for the exchange of information and for interaction among individuals in real time, making transport and distance no longer a problem. There are approximately 2.4 billion people on earth who has access to the internet with over 70 percent of them using the internet at least once a day. This amounts to a total of 144 billion emails being sent every 24 hours (internet world statistics, 2012). What started out as a hobby for some computer literate people has become a social norm and way of life for people around the globe (Boyd, 2007). The Caribbean consist of approximately 42 million people, 32.4% of which, use the internet (internet coaching library , 2012). Internet use has become very popular in many areas as well as in education in recent years. Accordingly, Internet access in schools has increased greatly over the last 20 years (Berson, 2000). In a research article, Ying-Fang Chen and Samuel S. Peng (2005-2006 academic year juniors) A study done on a variety of randomly selected University students in Taiwan showed that heavy Internet users and non-heavy Internet users differed significantly on a number of dimensions. Non-heavy users had better relationships with administrative staff, academic grades and learning satisfaction than heavy Internet users. Tuckman (1975) defined academic performance as the apparent demonstration of understanding concepts, skills, ideas and knowledge and proposed that grades clearly depict the performance of students. Heavy users were more likely than non-heavy Internet users to be depressed, physically ill, lonely, and introverted. According to a journal of Education and Sociology done in Pakistan, Muhammad Musaud Asdaque, December, 2010. The use of the internet is one of the major factors affecting the academic performance and social life of university students. The number of hours spent on internet will affect the grades of students depending on if the internet is used for study purpose or social purposes. Many studies have been conducted regarding the type of information the end-users seek and obtain on the Internet and in which circumstances they prefer electronic sources to paper sources(Tenopir et al.2003).Also , students can gain from others knowledge and experiences, participate in chatrooms, share ideas and solutions. Teens spend approximately 2.3 hours online a day, 80 percent of that time, on social networking sites (Roiworld, 2010). Students who multi-task between social networking sites and homework are likely to have 20% lower grades than a student who does not have a social networking site in visual range (Lenhart, A, 2009, April). Also , many researchers believe that excessive use of the internet has the potential to become an addiction (Griffiths, 1995, 2000). Some, involvement on the Internet begins to have serious, negative consequences. When such consequences are minimized or ignored while Internet use increases, Internet dependence is occurring. As of 2005, it is estimated that 6% of users are Internet dependent (Villanova Counseling Center). The internet can act as a major distraction to students if not properly managed. However, some studies show that students primary use the internet for school work specifically, searching the web for information needed for school projects (Kraut et al, 1996). This in turn, can improve the academic performance of a student. METHODS OF DATA COLLECTION PRIMARY SOURCES: In order to carry out the internal assessment on the impact of internet usage on the academic performance of adolescence students of St. Stephens College, research had to be done using both primary and secondary sources of data. The primary data collection source used was a questionnaire since it allowed the person time to answer questions and it was also cost effective. The questionnaire was also used because it allowed for data to be analysed easily and was not time consuming. A questionnaire is a means of research, consisting of a series of questions and other prompts for the purpose of gathering information from respondents. The questionnaire used consisted of 14 questions, 3 of which were open ended questions. The open ended questions were used to obtain qualitative data from the respondents. The other 11 questions were closed ended and were used to obtain quantitative data on the topic. A total of 60 questionnaires were distributed randomly across forms 1 to 6 students. The ran dom distribution ensured that there was no bias in the selection of candidates since each person had an equal chance of being chosen. SECONDARY SOURCES: The secondary sources of data included the internet, books and texts. This was done to gain a better understanding of the problem which was being investigated PRESENTATION OF DATA Map Showing Location Of Princess Town In Trinidad figure 1 figure 2 figure3 figure 4 figure 5 figure 6 figure 7 Figure 8: Diagram showing students who use the internet for aid in research Figure 9: Diagram showing other means of research used by students INTERPRETATION OF DATA Based on the results obtained from the 60 students investigated at St. Stephens College, it was found that most students ( 68% ) partake in online activities more than once per day while only 4% of them do not partake at all. This shows that while most students do have internet access , some do not and are therefore not affect by the effects of the internet. As indicated by figure 2, a majority of the students who do have access to the internet also spend between 1 and 3 hours online everyday ( 45 ) while 12 spend more than 4 hours online. The internet is used by students in various fashions as seen from figure 3. The number of students using the internet for education, entertainment, and communicating with others are almost corresponding. Coupled with the other activities as, passing time, shopping and work/business, it can be seen that most time spent on the internet is not for educational purposes. When the data from figure 2 and 3 are combined , it can see that 33 students students spend more than 2 hours online everyday and that most of that time would be spent idle and not constructive. However , from figures 8 and 9 , it can clearly be seen that all of the students that were selected, use the internet for aid in research, while in figure 9, students use more than one souurce of research. This included 32 choosing books, 21 using newspapers and 7 use journal as their source. Figures 8 and 9 show that students do accomplish work on the internet but not all information can be sourced there. Figure 4 shows that while there are 21 students scoaring acceptable grades at end of the term examinations (60-100%), there is still an overwhelming number of students performing under par (0-60%). This includes 39 of the 60 students. The table show that there is likely a link between the use of the internet and academic performance of the students. Larger quantities of students idle online resulting in greater quantities of students scoaring below average. The location of internet usage usually used by students are shown on figure 5. Most students use the internet either at their homes oor by a family members home. This accounts for 52 of the 60 students. The home is a place where most students relax and feel free and this may lead to them allocating more time idle on the internet as compared to a student who uses the internet at school where the use of the internet is controlled. The large quantities of students using the internet at home may be directly linked to the below average end of term examinations grades. Many of the students indicated that the internet was useful when it came towards academic work (95%), while the other 5% said otherwise according to figure 6. On figure 7, almost equal quantities of students both disagree and agree with the statement that the advantages of the internet outweigh the disadvantages. A total of 23 students agreed while 22 students disagreed , 15 students were neutral about the topic. The data shown from both figures 6 and 7 indicate that while large quantities of students do believe that the internet is useful towards academic work , it is easy to be distracted and held at an disadvantage instead of focus and be at an advantage . DISCUSSION OF FINDINGS The main objective of this study was to carry out an investigation about the impact of internet usage on the academic performance of students at St. Stephens College. The findings from the research done, inficated that the increased quantity of students using the internet corresponded to the high numbers of students whith low academic scores. This also corresponded to the research article done by Ying-Fang Chen and Samuel C.Peng (2005-2006) as their candidates who had heavy internet usage performed poorly with respect to academics. From the research done it was also found that students with internet access spend more time online, idle than doing assignments. Therefore students without internet access would spend more time constructive. One of the objectives of the research was to determine if students had become dependent on the internet . Althought many students admitted that the internet does help with research, many of them also refer to sources such as books and journals. This data lead to the conclusion that while students are quite heavily dependent on the internet , they are not totally dependent and are capable of using varyous sources for research. Overall, the results of this study compared to the literature review show that students are more negatively impacted upon by internet use as the internet, althought helpful at times, it a distraction to students. CONCLUSION The research study has clearly outlined the impact of the internet on the students of ST. Stephens College. It can be concluded that althought internet usage does have its benefits, the internet impacts more negatively on students as they are more distracted by online activities and spend less time doing work. Also, it can be concluded that althought students are heavily dependent on the internet, they are not fully dependant since they are capable of using various sources for information. LIMITATIONS Firstly, the sample for the study was selected from only one institute, therefore generalization of the findings to the total population is limited. Also, the study investigates the impact of the internet on academic performance. Other variables such as health, gender and social well-being may also affect performance, therefore future studies should not be as limited. RECOMMENDATIONS To improve the study done, more questionnaires could have been distributed to improve the accuracy of the study. Also, some students could have been interviewed to obtain a better qualitative report. To reduce the negative effect of the internet on students, schools can inform parents to manage supervise their childs internet usage to ensure that time is not wasted.

Flextime Policies Achieve Better Work Life Balance Management Essay

Flextime Policies Achieve Better Work Life Balance Management Essay The increased attention of issues relating to the implementation of flexible time arrangements to support work-life balance reflects significant economic and social changes at the individual and organizational level. Since 1950s, there has been a significant change of the standard working time (Bittman and Rice 2001; Blyton, 1994), resulting from the demand to increase flexibility without undermining cost factor.  As a result of the extended operating hours, businesses have experienced a much wider range of working hour arrangement, especially in the case of part-time and hourly workers.   The changes in the profile of labor market due to the increase in female participation in the workforce, the rise of single-parent and dual-income families and the increased number of workers in sandwich generation ,the growth on expenditure and debt levels, and the prospect of boundary-less work organizations in the future pose critical questions about peoples current and future ability to satisfactorily integrate their work and home-lives, the support system available to facilitate that integration, and more broadly, the role and value of work and consumption in contemporary society (Ransome, 2005; and Schor, 1999).   There is no one that fits for all solution to the issue of implementing flexible time policy in the workplace. The case study demonstrates that different policies, practices, and strategies will be needed to address the issue of flex-time conflict. Furthermore, we will analyze the role of communication, monitoring, and information sharing to achieve optimal benefit from flextime. By using flexible work arrangements, employers give employees a sense of control and empowerment.  This will lead to reduced cost from absenteeism, lower level of productivity, increased stress level, increased turnover and replacement. Introduction We have seen the images of working adults, trying to balance the burden of having a spouse, children, or elders to support, and work-related issues, usually coping with deadlines and increased work pressure, on the other. The balance is brittle, if they spend too much time at work, their family will suffer and vice versa. The role of work has changed, from zero-sum game to win-win interactions largely because of changing economic and social conditions (Harris Marmer, 1996). Win-win situations can be achieved by arranging work-schedules to meet work-family demands, making priorities, using employment-related resources, and having access to behavioral and emotional support from others especially employers (Friedman Greenhaus, 2000). One of the biggest challenges for organizations has been how to respond to the economic and social changes that alter the working environments. In response, many work organizations are introducing a variety of innovative approaches to cope with the changes in working roles and structures. Once perceived as a matter of necessity and survival, work is now seen as a source of personal satisfaction. One of the vehicles to attain balance and fulfill personal satisfaction is flexible-time arrangements. In the next section we concentrate on how this fashionable term has evolved and discuss problems related to the implementation of the program.    Key Concepts Research on work-life balance started in the mid-1960s ( Rapoport Rapoport, 1965 ) and developed from the focus on women and work-family conflict, to a more recent focus on all employees. However, the term work-life balance is a misnomer. The phrase indicates that work is separate from life, although work is increasingly dominating peoples lives. Furthermore, the word balance seems to imply that there is a trade-off between work and life, yet they are not necessarily mutually exclusive (Kanter, 1977). Parasuraman and Greenhaus introduced the term work-life integration to overcome the problem of work-life balance (1997). The idea is to integrate work and personal lives rather than seeing them as two separate domains that rule out one another, thus have to be balanced. However, one misunderstanding of the term integration is that it implies work and personal life must be integrated in the sense of merging each other, eliminating the possibility of integrating the two by deliberately keeping these domains separate (Lewis Cooper, 1999). As a result, the word harmonization has been introduced to relate work and personal life domains in harmonious ways without ruling out one another or merging these domains together (Gambles, Lewis, Rapoport, 2003). For simplification purpose, we will not delve into the issue of these terms and use the term work-life balance interchangeably with work-life harmonization or  work-life integration.   Ballard and Seibold (2004) stated that flexibility pertains to the degree of rigidity in time structuring and task completion plans.   Flexibility is categorized into flex-time, job sharing/part-time work, and telecommuting  (Hall Richter, 1988; Sullivan Lewis, 2001). Flex-time is a simplified term that describes flexibility in work schedules and hours. Employees can manage their work days within core-hours the hours which employees must present at work, usually between 10:00-14:00- and a bandwidth the earliest and latest starting and finishing times built around core-hours to which they can choose to adjust (Christensen Staines, 1990). There is no universal definition of standard work days due to different legislations across countries.however, we assume that it is defined by 40-hour and five-day working week. The Current Flextime Trend in Canada Flex-time programs are common in Canada and the trend reflects employers belief on that flex-time implementation results in better business performances. According to Statistics Canadas 2003 Workplace and Employee Survey (WES), which sampled 20,834 employees from 6,565 workplaces, approximately 57% of all working Canadians are already using flex-time programs, including compressed workweek and flexible work schedule. In the study, Flexibility: Whose Choice Is It Anyway? conducted by Cooke and Mann, they analyzed the WES data and discovered that flex time programs are implemented to improve business performances and minimize cost rather than to assist employees with their work-life balance. The Demographic Change The sandwich generation and workaholics are the two main groups of employees that are experiencing low satisfaction due to their poor work-life balance. According to Statistic Canadas General Social Survey (GSS), the sandwich generation population has increased from 670,000 in 2002 to about 2.7 million Canadians in 2007 (General Social Survey: Cycle 21, 2007). In 2002, it was estimated that approximately 27% of people age 45 and above are struggling to support both their children under 25 years old and their aging parents while working a full-time job (Williams, 2005). In fact, the latest GSS published in 2008 indicates a steady increase of sandwiched caregivers due to the late marriage trend, currently baby boomer generation are sandwiched in between family and work.   In addition to that, the increasing population of females in the workforce today also constitute to the proportion of the sandwich generation. There is an 11.6 % increase of all working women from 1976 to 2006 (Table 1). Increased education, desire for personal fulfillment, increased consumption, the high cost of living, and the high rate of divorce has contributed the growth in women participation in the workforce. In fact, according to the Statistics Canadas data collected in 2006, 73% of all women with children are part of the workforce (Almey, 2006). This indicates that families with children are more likely to have dual income from both the wife and the husband, leaving lesser time for individuals to take care of the family. 2005 GSS also collected data showing that there are 31% working Canadians aging 19 to 64 who think they are workaholics. Comparing to the non-workaholics, the majority of workaholics are unsatisfied with their current work-life balance. The large proportion of working Canadians who are unhappy with their work-life balance indicates the possibility that flextime can be a feasible solution to help with their stress in time management. Society also witnesses the increasing number of boomerang generation. Boomerang generation or boomerang kids are young adults age 20 and above that have returned from independence to live together with their parents. The growth of the boomerang generation is partly due to the economic condition and also to the multicultural family structure of Canada. According to Statistic Canada, 73% of Asian-Canadian families have adult children living with their parents whereas only 26% of Canadian born parents are allowing their adult children to live with them (Turcotte, 2006). Nevertheless, the boomerang generation relies partially on their parents in order to save the cost of owning and renting a house which helps maintain their desired lifestyle. Due to the emergence of the boomerang generation the burden has doubled for the aging baby boomers who have to continue working in order to take care of their adult children and the elders in the family (Canada Year Book: Society and community, 2008 ). The Caregivers Wish List In order to assist with the growing number of employees with work-life balance concern, Statistic Canadas 2007 GSS provides further data which include 712,000 caregiver aged between 45 and 64 and explore their major concerns with their work and personal life.   According to the statistics, 70% of sandwiched employees believe if the company provides more support and flex time programs, their work performance will improve (General Social Survey: Cycle 21, 2007). The following statistic is from Cara Williamss article, The sandwich generation, which shows the significant cost for sandwiched employees when they do not have access to resources that help them balance their work and personal life (2005).   Ã‚ ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  15 % reduced their work hours  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   20 % changed their schedules  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   10 % lost income  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   70 % are stressed out  Ã‚   Table 2 (refer to the Appendices ), The Caregivers Wish list, is a comparison of the needs from sandwiched employees to employees with elder care needs. The highlighted percentage of sandwiched employees shows that the top two wishes for both sandwiched employees and employees with elder-care responsibility are some form of workplace support such as flexible schedule and elder care to help accommodate their overwhelming responsibilities (Williams, 2005). Overall, both statistic and employee survey suggest that flexibility is a major attribute that potential employees consider in a company. Flextime Policies The adoption of flexible time policies differ widely by the level of public provision and culture of the organization. Some researchers argue that laissez-faire market stimulates employees concern of work-life programs, whereas others argue that public provision creates a climate which employers become active in pursuing this entitlement (Lewis, 1997). Den Dulk (2001) further reinstates that active government provision does not translate into the disappearance of the motivation for employers to implement work-life programs. Poelmans and Sahibzada (2004) summarize all factors that may influence the adoption decision. They argue that the probability of an organization to address work-life conflict is a function of the macro-level context in which the organization runs the business. The country level context is related to employees sense of entitlement to receive support from their employers, whereas the labor market context affects employees choice and negotiation power over organizati ons work-life policies, thus increasing the pressure on firms to implement them (Poelmans Sahibzada, 2004). The complete factors that influence organizations adoption decision is presented in Table 3 (refer to the Appendices ). Organizations need to decide the flexible work arrangements that suit their business model and the needs of the workforce. Business model that requires employees to meet fluctuating demands from clients outside work hours may implement flexible work arrangements. In fact, flextime is ranked more favorably than reduced-time schedules because many (full-time) employees with family responsibilities cannot afford to work less than standard full-time schedule (Rodgers, 1992). Benefits Employees that benefit from flex-time include working parents, especially working mothers, who want to be involved in their childrens lives while having the balance of having a family and a career at the same time. At Bristol Myers Squibb, 72% of those who worked flexible hours in 2003 were female (Poelmans Beham, 2005). Flextime options are excellent recruiting and retention tools. An article in the Long Island Business News interviewed many executives and found that they agree that investment in such programs shows that the company cares about their employees well-being and increases the companys attractiveness to highly skilled people who might not be ready to go back into the workplace on a full-time basis or just need flexible schedules (Starzee, 2009). In a survey by Careerbuilding.com in 2008, 54% of 7600 workers felt that companies offer flexible work arrangements to help manage stress levels and work life balance. 90% of American employees also feel that they are more value d by their companies if given the option of flexible schedules (Sweeney, 2003). Benefits offered depend on the type of job, industry or the employees.. With the right employees and good implementation on the part of management, costs of flex-time policies should be much less than replacement costs, which includes recruitment, hiring, training, and orientation. Even for an entry level position, replacement costs can exceed $10,000, not including lost time, energy and effort of management (Bednar, 2010). Using this strategy, companies can keep their top talent happy and reduce turnover. When the same employees stay with the company for a long time, they can provide better service for clients due to increased experience. Absenteeism is also likely to decrease since employees are more motivated to work when they feel they are valued by the company by giving them options to help them juggle their home and work demands. Table 4 in the Appendices lists the possible advantages of flexible work arrangements. Costs There are also costs to implementing flex-time policies. First of all, it is not one size fits all. Most employers identified through years of experience that many employees might not have the same motivation to work hard and get work done by staying late if they were given the option of coming in after the official start time (Bednar, 2010). Therefore, monitoring is essential to ensure that employees are not taking advantage of the policy. In order to properly and effectively implement a flex-time policy, employers need to introduce a series of new rules and procedures to manage the flexible workers and culture change, such as stricter punctuality and related provisions to ensure the equal, or even higher level of productivity. It is a burden and a risk for management. They are also required to monitor the performance of flexible employees with different measures to reduce scheme risks and achieve work goals. Secondly, starting such programs requires a great amount of communication to the employees about the availability and details (Bitti, 2008). Regardless of the results, management must spend time and effort in the attempt to make flex-time work. Productivity could decrease, service level might be lowered and lead to customer dissatisfaction, and employee dissatisfaction might also arise if they believe the arrangements were unfair.  Flex-time is not always supported by all employees, even though it is mostly considered as a benefit for employees. In 2008, a Deloittes survey of more than 1600 workers showed that 39% respondents agreed that taking advantage of formal flexible work policies including flex-time would harm their career. Based on the survey, employees are more comfortable with informal policies, such as taking time off for personal activities, if leaders are more open about their own needs and practices (CFO, 2008). To further complicate the matter, flex-time was seen as both alleviating and generating stress and was generally seen to have a negative impact on opportunities for learning and advancement (Kelliher Anderson, 2008). Some businesses cannot adjust their employees work schedules, because such a change would not fit their business (Wensley, 2008). A client may call in looking for something immediately, and the person with the flexible schedule is absent (Starzee, 2009). These potential negative effects may lead managers to be more conservative about implementing flex-time options. Despite all costs associated with the implementation of flex-time policies, employers that provide greater flexibility have been found to be related with higher perceived organizational performance (Perry-Smith Blum, 2000); resulted in increased shareholder return (Arthur, 2003). In addition, flextime policies create a favorable view of the organization, thereby suggesting that the organization is more attractive to job seekers (Casper Buffardi, 2004). In fact, many of the industry leaders listed in the Best 100 Companies to Work For in Fortune Magazine provide excellent flextime policies that better integrate work-family life of their employees. Case Study:   Kraft Foods, Inc. Kraft began to support work-life balance programs after a national employee survey in 2000 showed that the major challenge for most Kraft employees was finding balance between home and work-life. The survey also indicated that Kraft hourly workers that account for 59% of Kraft employees were the least satisfied with their work-life balance among all the employee groups. To overcome the problem, Kraft introduced the Fast Adapts program. Initiated in December 2002, Fast Adapts allows workers to swap shifts, take single day vacations, and request job sharing arrangement from their supervisor. Fast Adapts program was published in the company newsletters and broadcasted on the video monitors. The program was also communicated in the regular plant-wide meetings.    The flexible arrangement enables employees who are out on leave because of extended illness, family issues, or taking vacations to switch shifts with other employees. All hourly workers are eligible to use Fast Adapts program, given that the arrangements are aligned with work process, plant policy, or union contract. If not, employees are encouraged to discuss their situation with Human Resource managers to find alternative work solutions. To evaluate the effectiveness of this program, information about employee satisfaction was collected in the first quarter of 2003. The biannual survey showed improvement in hourly employees satisfaction with work-life balance. Conclusion The repetitive nature and inflexible schedule of the job in Krafts working site contributed to the decreased level of work-life balance satisfaction among hourly employees. Krafts Fast Adapts program has been successful for some reasons. Employees receive more autonomy over their work schedule, thus they are able to better integrate work-life demands. Plant managers also need to be more accountable, as they have to develop flexible work arrangements that work best for each individual plant. Fast Adapts program also encourages employees to communicate their needs to employers. The other key issue is to understand that flexibility should be an ongoing and mutual commitment between Kraft and its employees, win-win situation can only be achieved if both sides work toward Krafts vision of a supportive culture.

Philippine Attacks :: essays research papers

ZAMBOANGA, Philippines (AP) - Philippine forces launched attacks on three southern islands in an effort to wipe out the guerrillas who held a U.S. couple hostage for more than a year, military officers said Sunday. The assaults, which started Saturday after one of the Americans and a Philippine captive died in a rescue attempt, are aimed at the top three commanders of the Islamic militant group Abu Sayyaf, said Philippine Maj. Gen. Ernesto Carolina. Martin Burnham, 42, and Ediborah Yap, 45, died in a shootout Friday when government troops ambushed their captors in jungles of the main southern Philippine island of Mindanao. Burnham's wife Gracia was shot through the thigh but rescued. "We're now operating with greater ZAMBOANGA, Philippines (AP) - Philippine forces launched attacks on three southern islands in an effort to wipe out the guerrillas who held a U.S. couple hostage for more than a year, military officers said Sunday. The assaults, which started Saturday after one of the Americans and a Philippine captive died in a rescue attempt, are aimed at the top three commanders of the Islamic militant group Abu Sayyaf, said Philippine Maj. Gen. Ernesto Carolina. Martin Burnham, 42, and Ediborah Yap, 45, died in a shootout Friday when government troops ambushed their captors in jungles of the main southern Philippine island of Mindanao. Burnham's wife Gracia was shot through the thigh but rescued. "We're now operating with greater intensity. We will not let them get away with this," said Carolina, head of southern Philippine forces. He said no clashes were reported as of Sunday morning. Carolina said 1,500 and 1,800 soldiers would arrive in the next three days to back troops already hunting the Abu Sayyaf on the islands of Jolo, Basilan and the province of Zamboanga del Norte on Mindanao. "We will have to finish this war because terrorism is a scourge on the Earth," President Gloria Macapagal Arroyo said Sunday. All three mountainous, jungle-covered areas stand in a 60-mile stretch of the Sulu Sea in the southwestern Philippines. It wasn't clear how many troops were already involved in the operations, but thousands of soldiers have been in the area for months - since the military launched its offensive after the Abu Sayyaf seized the Burnhams and several other hostages in May 2001. Carolina said soldiers on Mindanao were hunting Abu Sayyaf leader Abu Sabaya, who fled into dense jungle with about 40 men after the army attacked them during Friday's rescue mission. (AP) Philippine President Gloria Macapagal Arroyo, right, extends her condolences to the family of slain.

Blake :: essays research papers

In Blake's "London" the speaker connects various characters and socio/political institutions in order to critique the injustices perpetrated in England. The busy, commercial city of London functions as a space in which the speaker can imagine the inescapable interconnections of English institution and citizens. Although separated by differences of class and gender, the citizens of London brush up against each other so that the misery of the poor and dispossessed is a direct indictment of the callousness of the rich and powerful, f the institutions of state and religion. The speaker of the poem emphasizes the social and economic differences that separate the citizens of London. By repeating the word "charter'd", he reminds the reader of the commercial nature of the city, the fact that portions of it are owned, and that not everyone has equal access to goods or property. In the first line of his poem as Blake speaks of how he is wandering through the "charter'd" streets, he is commenting on this commercial aspect of London. As he moves on in his poem he also refers to the "charter'd" Thames, he is telling us in this second line that even a river which is a force of nature, is owned in London. When Blake says that he sees "marks of weakness, marks of woe" in "every face" he meets, he means that he can see how this commercialism is affecting everyone rich and poor. Yet, despite the divisions that the word charter'd suggests, the speaker contends that no one in London, neither rich or poor, escapes a pervasive sense of misery and entrapment. The speaker talks of how in "every cry of every man" he hears the misery. Blake is once again reminding us that this is affecting everyone. As he goes on to comment on he can hear it in "every infants cry of fear", he is saying that even the babies know what is going to happen to them when they grow up and they fear the misery that they will soon face. In the next line of the poem Blake chooses to use a very interesting word. When he writes "in every ban" he leaves the line open to many different interpretations. The word ban can mean a political prohibition, a curse, or an announcement of marriage. The political meaning is an obvious one in this poem, Blake obviously does not like the politics of London and he fells that the commercialism is preventing the people from being happy.

Short Story Esay – on the Side Walk Bleeding

A short story in which a material object becomes important is â€Å"On the Side walk Bleeding† by Evan Hunter. With reference to the text I will identify the object and explain it's significance. In the opening paragraph the author gives a detailed description of a jacket which is worn by the victim of an attack. â€Å"The boy's name was Andy, the name was delicately scripted in black thread on the front of the jacket, just over the heart. On the back of the jacket it has the slogan ‘THE ROYALS'† this is the gang he is associated with. The Royals' are rivals to The Guardians. Being a Royal lead to Andy’s death. When he goes out for a pack of cigarettes he is violently assaulted by a member of The Guardians. The gang member said, with volume, â€Å"That's for you Royal! †. This tone insinuates that he had a vendetta with the gang as he emphasises the word ‘Royal'. If Andy wasn't wearing the Royal's jacket he wouldn't have been attacked. As the s tory progresses there are two young love birds strolling down the pavement. They duck into the ally where Andy lay after he'd been attacked. They didn't realise that Andy was only a few feet away. Freddie, one of the couple, saw Andy and knelt down beside him, that was when he had seen the jacket and said â€Å"He's a Royal. † The couple are afraid to help him in case The Guardians attack them. This further reveals the significance of the jacket; a material object which caused him to be targeted and is stopping people from helping him. When Laura, Andy's girlfriend, goes searching for him she find him in the ally, dead. He was found 58 minutes after he had been stabbed but before he bleed to death he mustered up all his strength to try and take his dreaded jacket off in the hope that someone would attempt to help him. The jacket meant fear to any one and everyone if he had managed to take it off before, he would have been saved but he didn't do it earlier. ‘A Royal, huh? were the first words the police officer said when he had found the jacket only a foot away from his cold body. Laura tried to tell him that his name was ‘Andy' but the officer only saw a Royal and nothing else. The jacket was a label and his identity was lost whilst he wore it. The significance of a material object in the text is important because it symbolises his dedication to the gang. This not only resulted in him being targeted; it made people afraid to help him and ultimately because of the jacket, he was left to die. Jamie Blair

International Business Strategy Essay

The Shangri-La hotels and resorts initiated in 1971 with a flagship hotel in Singapore. The Hong Kong based hotel chain now has around fifty five deluxe hotels and resorts across the world. The Shangri-La currently has hotels and resorts in Asia, Middle East, Europe, and North America. Shangri-La hotels and resorts shall soon be opening hotels in the regions of the Maldives, the Philippines and in Bangalore, Mumbai, Thailand and India. We can concur from this rapid international growth of the Shangri-La that the hotel is expanding its operations to various countries and increasing its international presence. The hotel not only needs to devise strategies for entry but for overall operation as well with respect to human resource, marketing, services and general management. This paper shall discuss the intricacies of the entry strategy employed by Shangri-La Hotels & Resorts, the corporate strategy that it observes, the competitive strategy and the competitive business strategy that it exercises. The paper shall also perform a functional analysis of the Shangri-La Hotels and Resorts in terms of the Human Resource Management strategy that it exercises. The paper shall conclude by identifying key organizational dimensions that have been established through the study performed in the paper. Introduction to the Subject MNE The launching of Shangri-La Hotels and Resorts began in the 1971 with a flagship hotel, in Singapore. Till the year 2008 it has been recorded to have 55 deluxe hotels located in major cities of Asia, Europe, Australia, United States and the Middle East. Along with these the Shangri-La Resorts and Hotels bear alliance with their Sister Company the Trader’s Hotel that fulfills the catering requirements of business travelers. This chain of hotels was set up by Mr. Robert Kuok and now his nephew Mr. Edward Kuok Khoon Loong holds the position of chairman of the board for Shangri-La Asia Limited. Despite its ranking as a 5 star deluxe hotel, it has had quite a few unfavorable reviews. But it appears that the positive reviews far supersede the negative ones. For instance one guest reviewed the hotel as part spectacular and part unimpressive. According to this guest, The Horizon Club Premier room was far from the exemplary 5 star deal originally promised. However this guest goes on to suggest that while the Horizon Premier wing was unimpressive, when asked for a transfer to another wing, known as the Valley wing this guest was highly pleased, it was everything the hotel had promised and more. The luxuriant 5 star deluxe tagline was apparent in the spectacular yet cozy furnishing and the service was described to be incredible. Another guest however described the service of the hotel to be despicable. First not only were the details of their payments messed up, they were forced to pay more or if they could not, they had to move to the lowest paid room, which was a far cry from the luxurious settings of the Valley Wing, there they were submitted to zero rated service, as it appeared that only affluent guests were applicable to affluent treatment. However their being ushered into a lower class room meant that they were not worth the special brand treatment reserved for the high paying guests. Contrary to the above negative reviews, a couple who stayed at the Shangri-La Hotel described the treatment, services, luxurious settings and furnishings as unbelievably fantastic, they too stayed at the Horizon club and in contrast with above reviews, they described it as a highly pleasurable experience. Many such guests describe their stay at the Shangri-La hotel as a memorable and nostalgic experience. Every hotel despite its efforts at flourishing, obtains bad reviews, this most probably is dependent on the fact that environments are subject to every individual’s personal thoughts and interpretation, what was unpleasant for some, in contradiction was fantastically better for others. Motivations for Internationalization Internationalization is one of the major elements of growth for any enterprise or organization where companies take advantage of the global business environment involving various countries in the world. There are various factors that motivate companies to invest internationally and expand business from local to international levels. These factors include exploring new markets and taking advantage of growth patterns of certain industries in various countries. The Shangri-La hotel also focuses on new markets where there is good potential for hotels and resorts. Take the examples of India, U. A. E, Australia, Thailand and Maldives. These markets are becoming tourist destinations for individuals from all around the world. These countries are not only tourist destinations but also offer attractive environment for businesses like hotels and resorts. Another motivation for the hotel to internationalize is the lower cost of doing businesses in various countries and high level of revenues the hotel can generate from those areas. The foreign exchange a company earns by doing business abroad is also one of the causes of internationalization. Various countries also offer lower tax rates in various specific industries such as hotels, education and other industries. Shangri-La has gained from opening hotels in new locations both financially and in terms of goodwill. As the company opens new hotels and resorts in various locations, it draws closer to becoming a member of the highly reputed hotel chains of the world. The hotel has to keep up with the challenges being faced in the new locations both regarding the culture of the local populace and catering to the tourists flocking to these locations. The hotel has not only opened in various locations but the plans for extending to newer location and increasing the number of hotels in the present international locations identifies the hotel management’s ideology regarding internationalization. As the company benefits in terms of revenue and status from the international locations, its local popularity grows as well as Shangri-La now signifies a multinational hotel resort chain with five star hotels and resorts at various international locations catering to the needs of a diverse clientele base. The intention of opening hotels in U. A. E and Maldives implies how far the management is willing to go to introduce the hotel chain to newer markets and benefit from the hotel and resort friendly atmosphere in these locations despite of major cultural differences. The hotel chain invests in culturally viable human resource to tackle with the cultural differences and relies on a local and expatriate workforce as well. The hotel like other multinational companies depends heavily on these foreign locations for a constant and sustainable growth which is the most significant cause of internationalization of Shangri-La hotel and resorts chain. Functional Analysis – HRM Modern day Hong Kong based multinational organizations are choosing to establish a work force they can rely on to provide them with a working infrastructure that can adapt to various cultures. This is because of the fact that for multinational hotels, the aspect of human resource adaptability has become just as important as the professional abilities that the candidates posses. This becomes all the more significant in scenarios where hotels and hospitality establishments such as Shangri-La Hotels & Resorts are concerned. In the last few decades, the trend of hiring culture adaptable human resource has undergone a significant degree of growth. This is because of the fact that in order to cater to a global clientele and to serve them, it is essential that the elements performing the services are well versed in the language of the clientele. In order for the working elements of hospitality to function on a global scale, they have to be capable of thinking on a global scale. Albeit, one cannot ignore the fact that their functioning will be within a perimeter where foreign clientele will visit, therefore, it is essential to note that the human resource has to be proficient in the areas involved in the functioning of the immediate locale as well. Because of the same reason, hotels & resorts such as the Shangri-La Hotels & Resorts now choose to hire personnel who can entertain clients from all over the world with the same degree of hospitality. The candidates that Shangri-La Hotels & Resorts now seek out are ones who can be cordial, sociable and have former experience in the area of adapting to clients from across the world with a consistent degree of hospitality. For Honk Kong based Shangri-La Hotels & Resorts, knowledge of the language of an immediate region is just as essential as the knowledge of the language used by their clientele from across the world. As Hong Kong based multinationals prepare to expand, the need for personnel who can not only function but also manage the infrastructure at the same time increases. The room for errors is decreasing exponentially over time. The Hong Kong based multinationals are also searching for a workforce which includes people who are affordable. Due to a substantial rise in the operating costs, doing business in Hong Kong has become more expensive in the last ten years. The firms based in Hong Kong are not enthusiastic about giving the incentives and bonuses to foreign workers as they did earlier. The same goes for Shangri-La Hotels and Resorts, the cost of doing business has affected the human resource policies in hotel management as well. The companies based in Hong Kong including hotels such as the Shangri-La now offer a salary package that includes housing and living costs on into the basic salary. The companies are also starting to offer performance based salary arrangement which are more attractive to new employees (Meijob. com 2008). Entry Strategy  There are three factors which determine the entry strategy for any hotel into international markets which are control of the hotel, commitments of resources and level of risk diversification. The entry strategies available to hotels include complete ownership, franchises, management contracts, joint ventures, strategic alliance and forming a consortium. The entry strategies adapted by Shangri-La hotels for various international locations include sole-ownership, management contracts and equity participation in the form of joint ventures or strategic alliances. These strategies vary from location to location depending on the specific environment of the host countries. The company operates sole-ownership hotels in countries where the gain on real estate is higher and the hotel operations are profitable and have a good potential for growth. In countries where a significant level of risk is involved the company opts for other options such as management contracts where direct ownership of real estate is either not possible or not viable for the company. The hotel chain uses joint ventures in areas where the cost of doing business and the cost of capital is quite high or in locations where there are certain property ownership constraints. The hotels established by the company in various areas were the first luxury hotels of the area and in some areas the company provided luxury hotel services solely. The company had signaled a long term planning structure for the time to come as in 1989 the company started a second hotel chain called Traders. This was a four star mid-ranged hotel brand with lower level of standards than the company’s main hotel chain. The company amended the newly acquired chain and upgraded services to meet the current luxury levels of Shangri-La. The main ideology behind this amendment was to introduce the concept of luxury hotels to newer markets and eventually establishing five star luxury hotels in these regions. Again this market entry strategy reflected the company’s long term goal to take luxury hotels and resorts to newer locations. Though the hotel chain saw difficult times the company gained substantially from its investments in China as the economy of the country flourished. In the starting of the new century the company amended its entry strategy slightly to adapt to global conditions. The company had now acquired hotels in Dubai and Canada. The growth of the company enabled it to open various hotels in different locations during 2000-2005 and there is a long list of hotels which are being planned for newer locations. The entry strategy for global locations has now changed slightly as these markets are already familiar to luxury hotels. The company now aims to gain from its reputation as one of the largest hotel chains of Asia. The company invests heavily in areas with high tourism capacity and targets areas which have a high potential for luxury resorts such as Dubai, Maldives, Thailand and Malaysia which have now become tourist hubs for individuals from around the world with diverse cultural backgrounds.

A Brief History of the Hybrid Vehicle Essay

First built in the early 1900s by inventors tinkering with combinations of the electric motor and the gasoline engine, hybrid vehicles were dropped when gasoline-fueled vehicles became more reliable and easier to start, and gasoline fuel more readily available. Research and development of hybrid vehicles was revived by concern about oil dependency in the1970s and about air pollution in the late 1980s. A number of hybrid vehicles have been built and tested since 1980. Some of these vehicles have impressed analysts with their performance and low levels of exhaust and petroleum consumption. Interest in hybrid vehicles jumped in late 1993 with the announcement of funding for two major collaborations. The US Department of Energy signed a five-year, $138 million development agreement with General Motors and a $122 million agreement with Ford to design and build preproduction hybrid prototypes that could be marketed in less than 10 years. [1] All these were done because hybrid electric vehicles are expected to be the future of vehicles worldwide. Definition One considers a vehicle to be a hybrid when it combines two or more sources of power. For example, a mo-ped (a motorized pedal bike) is a hybrid because it combines the power of a gasoline engine with the pedal power of its rider. Similarly, the gasoline-electric hybrid car is a combination of both an electric car and a gasoline-powered one. That is, it makes use of both electricity and gasoline to provide the energy to turn the wheels of the car. Figure 1 shows a gas-powered car. [2] Components Of A Gasoline Powered Car The 4-cylinder engine converts gasoline into motion so that the car can move. The easiest way it does this is to burn the gasoline inside the engine. Therefore is acts as an internal combustion engine i. e. combustion takes place internally. Gasoline powered car engines typically have over 100 horsepower and operate at speeds up to 8000 RPM. The fuel tank stores and supplies gasoline to the engine. It can typically store enough fuel to provide the engine with energy capable of moving the car through a distance of 300 miles or more. Figure 2 below shows an electric car, which has a set of batteries that provides electricity to an electric motor. The motor turns a transmission, and the transmission turns the wheels. [3] Components Of An Electric Car The batteries store and provide energy to the electric motor in an electric car just as the fuel tank does for the engine in a gasoline powered car. It usually gives the car a range of 50 – 100 miles which is much less than that typically provided by a fuel tank (300 miles). The electric motor is the device that provides motion in an electric car. It converts the energy it receives from the batteries into motion which is used to turn a transmission which then in turn rotates the wheels. It is able to spin up to 15000 RPM and has up to 100 kW of power. Since this motion is connected to the transmission, the transmission also spins the wheel up to this rate. Thus, electric cars would tend to move faster than gasoline powered cars. Components Common To Both The Electric Car And The Gasoline Powered Car The transmission is the device that does the actual turning of the wheel in both cars. There are several ways of combining the two sources of power found in a hybrid car. The Parallel Hybrid Car: This has a fuel tank which supplies gasoline to the engine. In addition, it has a set of batteries that supplies power to an electric motor. Both the engine and the engine motor can turn the transmission at the same time and the transmission then turns the wheels. Figure 3 shows a typical parallel hybrid. The fuel tank and gas engine connect to the transmission. The batteries and electric motor also connect to the transmission independently. As a result, in a parallel hybrid, both the electric motor and the gas engine can provide propulsion power. The Series Hybrid Car: The gasoline engine in this car turns a generator and the generator can either charge the batteries or power an electric motor that drives the transmission. Thus the gasoline engine never directly powers the vehicle. All of the components form a line that eventually connects with the transmission. [4] Hybrid Components Gasoline engine – The hybrid car has a gasoline engine much like the one you will find on most cars. However, the engine on a hybrid is smaller and uses advanced technologies to reduce emissions and increase efficiency. The engine turns the generator. It is not able to power the car directly. Fuel tank – The fuel tank in a hybrid is the energy storage device for the gasoline engine. Gasoline has a much higher energy density than batteries do. For example, it takes about 1,000 pounds of batteries to store as much energy as 1 gallon (7 pounds) of gasoline. Electric motor – The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. Generator – The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids. It is where the gas engine’s power gets converted to electrical power to drive the motor or charge the batteries. Batteries – The batteries in a hybrid car are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy into the batteries as well as draw energy from them. They can store energy recovered from braking or generated by the motor. Transmission – The transmission on a hybrid car performs the same basic function as the transmission on a conventional car i.e. turns the wheels. The motor can spin fast enough so that the transmission needs only one gear. Some hybrids, like the Honda Insight, have conventional transmissions. Others, like the Toyota Prius, have radically different ones like the CVT. CVT stands for Continuously Variable Transmission. It is used to vary the transmission ratio in vehicles continuously. The way CVT works depends on the type: Friction CVTs vary the radius of the contact point between two rotating objects, thus the tangential velocity; Hydrostatic CVTs vary the fluid flow with variable displacement pumps into hydrostatic motors; Ratcheting CVTs vary the stroke of a reciprocating motion, which is connected to a free-wheel, resulting unidirectional rotation. Image courtesy DaimlerChrysler The Mercedes-Benz M-Class HYPER — a hybrid concept vehicle[5] Reasons For The Introduction Of Hybrid Electric Vehicles To reduce tailpipe emissions: Gasoline cars are a major source of these emissions. Many attempts are being made by several organizations to reduce the greenhouse gas emissions from cars through the development of hybrid electric vehicles. For example, Nutley, NJ-based Hoffman-La Roche, Inc. (Roche), the U. S. prescription drug unit of the Roche Group, recently announced plans to integrate Toyota Prius and Ford Escape hybrid electric vehicles into its pharmaceutical sales fleet in an effort to help achieve the company’s goal of reducing greenhouse gas emissions by 10 percent over the next five years. [6] To improve mileage: Automakers in the US need to meet Corporate Average Fuel Economy (CAFE) standards as required by law. At present, all new cars sold should be 27. 5mpg (8. 55 liters per 100km). [7] To overcome the shortcomings of an electric car: Electric cars have a short charge. They lacked the range (energy density of electric-vehicle batteries hovered around 70 to 100 watt-hours per kilogram, which automotive engineers called unacceptable) and the quick recharge time the auto industry said it needed. An example is seen in the case where GM introduced the EV1 in 1996. It had a top speed of 183 MPH, faster than any other production car out. It had a limiter that would not let it get above 85 MPH, because to drive the car at 183 MPH would deplete the batteries of their charge within 10 minutes. [8] Energy Consumption: Hybrid Electric Vehicles consume less energy than Internal-Combustion Engine (ICE) vehicles. [9] Why Are Hybrid Electric Vehicles A Better Choice? An important aspect of hybrid electric vehicles is that they make use of smaller engines. There are many advantages to this: Big engines are heavier than smaller ones so the car uses more energy anytime it accelerates or drives up a hill. The displacement of the cylinders is larger so each cylinder requires a greater volume of fuel. Bigger engines usually have more cylinders, and each cylinder uses fuel every time the engine fires, even if the car isn’t moving. These are the reasons there is a difference in the mileage of two cars of the same model with different engines. If both cars are driving along the freeway at the same speed, the one with the smaller engine uses less energy. Both engines have to output the same amount of power to drive the car, but the small engine uses less power to drive itself. In a hybrid car, the gasoline engine can be much smaller than the one in a conventional car and thus can be more efficient. The engine in the hybrid car is powerful enough to move the car along on the freeway, but when it needs to get the car moving in a hurry, or go up a steep hill, it needs help. That â€Å"help† comes from the electric motor and battery — this system steps in to provide the necessary extra power. The gas engine on a conventional car is sized for the peak power requirement (those few times when you floor the accelerator pedal). In fact, most drivers use the peak power of their engines less than one percent of the time. The hybrid car uses a much smaller engine, one that is sized closer to the average power requirement than to the peak power. Ways Hybrid Electric Vehicles Reduce Energy Consumption Besides a smaller, more efficient engine, today’s hybrids use many other tricks to increase fuel efficiency. Some of those tricks will help any type of car get better mileage, and some only apply to a hybrid. To squeeze every last mile out of a gallon of gasoline, a hybrid car can: Recover energy and store it in the battery – Whenever you step on the brake pedal in your car, you are removing energy from the car. The faster a car is going, the more kinetic energy it has. The brakes of a car remove this energy and dissipate it in the form of heat. A hybrid car can capture some of this energy and store it in the battery to use later. It does this by using â€Å"regenerative braking. † That is, instead of just using the brakes to stop the car, the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing down. Sometimes shut off the engine – A hybrid car does not need to rely on the gasoline engine all of the time because it has an alternate power source — the electric motor and batteries. So the hybrid car can sometimes turn off the gasoline engine, for example when the vehicle is stopped at a red light. Figure 5. The frontal area profile of a small and large car Use advanced aerodynamics to reduce drag – When you are driving on the freeway, most of the work your engine does goes into pushing the car through the air. This force is known as aerodynamic drag. This drag force can be reduced in a variety of ways. One sure way is to reduce the frontal area of the car (Figure 5). Think of how a big SUV has to push a much greater area through the air than a tiny sports car. Reducing disturbances around objects that stick out from the car or eliminating them altogether can also help to improve the aerodynamics. For example, covers over the wheel housings smooth the airflow and reduce drag. And sometimes, mirrors are replaced with small cameras. Use low-rolling resistance tires – The tires on most cars are optimized to give a smooth ride, minimize noise, and provide good traction in a variety of weather conditions. But they are rarely optimized for efficiency. In fact, the tires cause a surprising amount of drag while you are driving. Hybrid cars use special tires that are both stiffer and inflated to a higher pressure than conventional tires. The result is that they cause about half the drag of regular tires. Use lightweight materials – Reducing the overall weight of a car is one easy way to increase the mileage. A lighter vehicle uses less energy each time you accelerate or drive up a hill. Composite materials like carbon fiber or lightweight metals like aluminum and magnesium can be used to reduce weight. [10] Despite the advantages of hybrid vehicles, they are a middling choice whose future is far from assured. They are likely to be a victim of regulatory circumstance in the near term, pushed aside by improvements in gasoline emissions and by the Zero Emission Vehicles (ZEV) mandate which states that a specified percentage of manufacturers’ sales consist of ZEVs. [11] In the longer term, they will be squeezed between improving batteries and emerging fuel cells. If only fuel cells and advanced batteries falter, hybrid vehicles would have considerable promise and could play a central role in creating a more sustainable transportation system. Nissan Motor Company CEO Carlos Ghosn announced that he is unsure whether hybrid electric vehicles (HEVs) will remain competitive in the compact car market if the price of gasoline drops in the future. Speaking at a news conference in Tokyo, Ghosn acknowledged that Nissan will unveil a new HEV in 2006 â€Å"as planned,† but only to meet tightening emission regulations in California. Ghosn expressed doubt that U. S. benchmark crude prices would remain at current levels of $50 per barrel, which is fueling strong demand for HEVs.
