“Remember The Titans” Directed by Boaz Yakin Essay

In the film â€Å"Remember the Titans† an important scene is at the Gettysburg battle location. Here, Boone makes an impacting speech to the players on overcoming their racism. Boone is the head coach of the mixed coloured football team he is speaking to. The film is set in the 1970’s, when racism is common. The Gettysburg scene has some visual techniques which helps one understand why it is important. One example is the silhouette with Boone the background. A verbal technique is the Boones voice is serious. Gettysburg is the turning point in the film, where the players over come their racism. At the football training camp in Gettysburg, the head coach Boone, takes them on a run at three o’clock in the morning. He takes them to the scene of the Gettysburg battle. The weather is foggy and damp. The mist from the fog, gives a softening effect on the cemetery behind Boone, when he gives his speech. The gravestones in the cemetery resemble the men killed in the battle. The gravestones also give the scene a serious effect. When Boone is speaking, one knows that what he’s saying is important because Boone is talking in a very serious and flat tone. â€Å"50,000 men were killed fighting the same fight you’re fighting.† The fight is the fight of racism. The men in the battle fought over political issues, including the use of the black slaves. The quote means that the players are fighting over racism, when the fight has already been fought with a drastic outcome. The tone of Boone’s voice is very serious, because it is clear and does not change tone. His voice impacts one because the only thing that can be focused on is the words. His voice helps me understand why it is important because he asks rhetorical questions and the words are powerful. â€Å"I don’t care if you don’t like each other, but you will respect each other.† When Boone speaks at the scene, he is standing in front of everyone, and the assistant coach, Yoast is standing with the players. This shows that Yoast connects with the players. During Boones speech there is a silhouette of Boone and the cemetery behind him. This gets the viewer to focus on the words he is saying, and the cemetery behind him, not on what he looks like saying them. â€Å"Did the die for nothing?† When he says this, the viewer is taking in what he says because one is focused on Boone himself and his words. When they get back to the camp, during a training session, the two captains shout the mantra, â€Å"left side† â€Å"strong side† to each other. This shows a new understanding and respect towards each other. They impact the rest of the team, which then come together as well. On the bus ride too the camp, the players are not talking to each other. In comparison to this, the bus ride on the way back to school, the players are all singing together. This is the turning point which shows me that Gettysburg is important. Overall I think that Gettysburg is an important scene because through Boone’s speech, the cemetery and the reactions after the speech, it shows that it affected the players because they changed from disliking and not trusting each other, to trusting and respecting each other. This shows that it must be important because of the result.

Big Fat Tax Analysis

In the article â€Å"Big fat tax is no gut buster† author Susie O’brien attacking the new tax on the fast food industry. By the opening slogan, â€Å"DON’T tax the big mac† she asserts her position on the tax. Written in bold the slogan immediately catches the eye and as it cleverly rhymes is very memorable. The author continues in cementing her standing on the issue by saying that a junk food tax is not the answer and the rhetorical question that, â€Å"why should reducing our weight start with our wallets? Her target audience with this piece would be those for the tax as she argues that there are downsides to a tax on fast food as well as alternatives that could be better. The image plastered in the centre of the article shows a man made of fast food. It relates to the subject of the article yet despite the amount of greasy fast food also seems appetising. The author also states that she is definitely for helping overweight Australians however that a fa t tax is not the answer.We see colloquial language which creates a feeling of comfortability with the author when she states a fat tax is such a, â€Å"one-pronged solution† whilst also dismissing the idea as small-minded. The tone she has written in persuades readers to agree as she says, â€Å"it (government) can remove every damned junk food vending machines from gyms, sport club houses and schools. † The power in which the author says this makes her statement a real rallying point as if she is part of a protest.Whilst loaded language like â€Å"damned† and the rhetorical/loaded question of â€Å"why do so many parents reward kids for playing sport with a packet of chips? † This sentence gives readers who do this a sense of guilt whilst those who don’t may find it amusing. She then goes on to give the audience someone else to blame for their fat with the rhetorical question of, â€Å"Why not start by cracking down on irresponsible food labellin g? She continues on with fact and research as she states that all our foods are, â€Å"choc-full of toxic ingredients like saturated fats, trans fats, palm oil and high-fructose corn syrup, which is one of the leading sweeteners in food, but is very hard for the body to effectively break down. † This makes the author seem knowledgeable on the subjects which can persuade readers into trusting her as she clearly knows what she’s talking about. The author gives many alternatives to a fat tax which seem simple to impose as well as logical to reducing obesity rates.The author proposes ideas such as setting up safer pedestrian walkways so that people (especially kids) may walk to places such as the local shops/schools. Inside these alternative solutions she can now turn it back on the fat tax by using loaded sentences such as, â€Å"Why does every social solution seem to involve taking money out of my pocket and putting it into Treasury? † as well as, â€Å"In short, if it (the government) wanted to, it could stop this problem in its tracks. But instead it's being told merely to increase taxes.Talk about punishing the victim. † The author befriends her audience and makes it seem like she’s one of us/on our side so that it persuades readers to come round to her view. Her use of rhetorical questions makes readers come to assumptions that she wants them to. Whilst also giving them someone to blame in the government alluding that they are simply out for out money. Her powerful final sentence, â€Å"So let's forget fads like tax on fast food, that will just make takeaways more expensive and will do nothing to change the way people live their lives.Let's do more to change every single day to make life healthier for everyone. † leaves readers with a sense of duty and that the author’s aim is simply to help us, the people persuading us to be against the fat tax. Susie O’brien uses rhetorical questions and loaded langua ge to coax readers into making assumptions about the government and the fat tax. Clever slogans and imagery helps her arguments be memorable as well as logical. She creates someone to blame as well as alternative solutions which makes a fat tax seem small-minded. This persuades readers to agree with her postion.

Japan Buys More of Euro Bailot Bond Article Example | Topics and Well Written Essays - 750 words

Japan Buys More of Euro Bailot Bond - Article Example Unlike Japan, other countries are not inclined to buy the European bonds because of the increasing debt problems which confront Europe. Even China which bought the bonds previously has not shown any intention of purchasing additional bonds. The financial crisis in Europe has made the yen stronger, making Japanese products less competitive than other products in the world. Because of this, the Japanese government has intervened in the currency market to weaken the yen, which was opposed by the European countries. It is not clear though whether this opposition by European countries triggered the reduction in the purchase by Japan of the EFSF bonds. The Japanese Finance Ministry defends its position by saying that the reduction in the purchase is based on the euro â€Å"liquidity† in its reserves and the conditions of the EFSF securities (Nakamichi , par 10). As a background information, the European Financial Stability Fund was set up in May 2010 with $625M. It was set up  "to bail out Greece to keep the turmoil caused by its debt from spreading to the euro-zone’s weaker members† (The New York Times , par 1). ... This article shows the importance of rescuing the European countries. Even if Japan is also beset with the problem of reconstruction after the devastating earthquake and tsunami last March, it still purchased the European bonds because it is aware that a recession in Europe will have a domino effect. Once European demand falls, the American, Japanese and Chinese economies will be adversely affected. Japan realizes that if the market confidence on the euro falls, there will be financial and trade disruptions. This scenario will lead to another global recession which the Japanese government would not like because their economy is export-driven. Since Japan has excess foreign reserves, the Finance Ministry decided on purchasing the Euro bonds to help the European economy. Next to China, Japan is known to have the world’s second-largest foreign-exchange reserves. The move of Japan to buy the Euro bailout bond is very commendable because one sees the concern of Japan to avert a wor ldwide crisis. Japan’s move means that they want to do their share in stabilizing the global financial system. The purchase of Euro bonds by Japan will help sustain the euro which has declined versus the yen. Hopefully, with Japan buying more Euro bonds, other countries will trust the deal more and purchase the bonds too to help Europe get out of the crisis. It will boost confidence in the EFSF further. Regarding Japan’s intervention to weaken their currency, one sees this as a move to help the country’s exporters. Having a strong yen makes Japanese goods more expensive for foreign buyers and would result in a decline in profit margins for the exporters. However, one does not see this as an effective way to improve its

Evolution of Revolution Essay Example | Topics and Well Written Essays - 1250 words

Evolution of Revolution - Essay Example Marlon Brancho is an American screen and stage actor of the film the wild ones. He brought realism to the film industry thus becoming influential. The film Wild One starred by Marlon Brando features on real life event that occurred in 1947 during a weekend in California whereby a gang of motorcyclists converged and dominated in a small Town for two days causing trouble without confrontation (Harris 5). In addition, Easy Rider is an American road movie acted in 1969 by Peter Fonda. On the context, it depicts two bikers traveling through American southwest and south to New Orleans to attend a Mardi Gras. They have an objective of achieving freedom. In their trip, Wyatt and Billy meet and took a meal together. They leave for Mexico where they bought drugs intending to sell it at the American border.

The film depicted extends of turmoil associated with the adolescent. The film directed by Ray gave both social commentary and unlike previous films it depicted delinquents in slums at urban environment. In my opinion, the movie acted in Hollywood had common themes used that showed such families as perfect avoided. In a further aspect, the rebel without cause considered American family as not perfect. In all cases, all have their missteps. I do not concur with the existence of as completely joyful families as rebels show the tortures among parents and mostly in youths (Ebert 7). We can see a rebellious teenager, who upon enrolling in his new high school after meeting a girl, disobeys his parents and goes against the schools bullies thus portraying the king of moral decay among American youths, critique parental style. From the film, it is seen that after James dies, the rebel was released.

The Work of Art in the Age of Mechanical Reproduction, Walter Benjamin Essay

The Work of Art in the Age of Mechanical Reproduction, Walter Benjamin - Essay Example The sense of originality has lost by use of pictures as compared to paintings. According to Benjamin, the reproducible film represents a historical shift that many audiences might fail to notice. Benjamin noted that the work of art reproduced mechanically has intervened to fill the void left by loss of aura. For instance, the loss of authority by the original work of art has been compensated by the use of a camera. Cameraman can direct the viewers eyes towards specific places and stories, as a result of being radical, revolutionary and totalitarian. Mechanical reproduction has introduced distraction as a new way of reception. There is a shift in the location of work of art that can be referred to as an aura to the mythological space. People are now capable of visiting places like museums, theaters, galleries and cinemas to see the work of art. Benjamin, however, complements the loss of aura. He notes that the loss has opened up politicization of the work of art put into use in different ways. He observes that a mechanical reproduction has managed to change contemplation regarding the screen as well as the films

Legal History of Film Streaming Websites Essay Example | Topics and Well Written Essays - 2000 words

Legal History of Film Streaming Websites - Essay Example One such disadvantage is the increased risk of infringement of the rights of copyright holders. The Internet provides a faster, cheaper and easier access to entertainment content which inevitably increases the risk of unauthorized reproduction, unchecked distribution and illegal public performance of copyrighted content. (Aspen Pub, 2001). The advent of new digital technologies has eased the circulation of movies around the world which has been and continues to be the source of tremendous problems for the entertainment industry. With the advent of movie streaming technology, an individual can view a movie without downloading it from the website therefore; the ease of viewing has been enhanced. There are a large number of legitimate and legal websites that enable internet users to view motion pictures, live sports events, TV programs and other forms of entertainment. However, the problem of unauthorized public performance of movies has intensified with the advent of illegal and illegi timate movie streaming websites. (Litman 2001). History of Video streaming websites and Copyright Law issues: The demand for online viewing of movies surfaced in the year 1997 and is now a $1.9 billion industry. In 2001 two major movie downloading websites surfaced which were Movielink and Moviebeam. Both websites failed to establish a profitable market place and were sold in the year 2006. Today, one of the major legal movie downloading sites is Apple iTunes along with Amazon, Veoh, Hulu, Netflix and Blockbuster. (Finney, Angus 2010). One of the fundamental issues that arose with widespread use of the Internet was violation of copyright laws. In 1997, the Congress enacted the No Electronic Theft Act in an effort to prevent the unauthorized uploading of movies and videogames. In accordance with Telecommunications Act of 1996, Internet Service Providers will not be considered liable of copyright infringements committed by their website users if they agree to promptly remove the unlaw ful materials from their website. The advent of social networking and film clips sharing sites such as MySpace and Youtube was soon followed by lawsuits filed by copyright owners. In accordance, Youtube was sued by Media conglomerate Viacom for $1 Billion for the violation of copyright laws as thousands of copyright videos were uploaded by Youtube users each day. Youtube and Viacom solved the issue by negotiating outside the court but officials from Youtube stated in court that they fall in the safe harbor category of Digital Millennium Copyright Act which states that the Violator will not be liable for the violation if they promptly remove the material blamed with copyright infringement. Therefore, both MySpace and Youtube acted to prevent the resurfacing of such an issue by installing specially designed internal filters which prevent the uploading of copyrighted material. However, the critics of such lawsuits believe that it is perfectly legal to upload copyrighted material under the fair use Doctrine. The year 2010 proved to be hugely successful for Google and Youtube because the Court dismissed the billion-dollar infringement claim filed by high profile lawsuits and declared that Youtube falls under the â€Å"safe harbor†

Research Paper for College Course -- Introduction to Microeconomics

For College Course -- Introduction to Microeconomics - Research Paper Example Smith is credited with being the first to examine the importance of the division of labor and worker productivity and for advancing the idea that free markets thrive on the basis of mutual self-interest. Although Smith warned against monopolies and mercantilism, his notion that markets are driven toward the public good by an "invisible hand" has made him a venerated figure among free market doctrinaires. (Answers.com). The purpose of this paper is to describe the pros and cons of free trade. Trade allowed nations to obtain the goods and services the population needed in order to survive. In the 20th century the ability to trade with other nations became a critical success factor for many nations including the United States of America. Today free trade is practiced by many nations in the world. More than ever before in history we see that free trade agreements are being sought by the world’s most powerful countries, as well as the developing nations. In short, free trade agreements are now high on the political agendas of many nations and the World Trade Organization. The globalization movement has been instrumental in forcing nations to enter into free trade agreement. In North America the free trade agreement that is enforceable is the NAFTA agreement. The NAFTA opened up free trade between the United States, Mexico, and Canada. â€Å"NAFTA was designed to promote economic growth by spurring competition in domestic markets and promoting investment from both domestic and foreign sources† (Teslik). The reason that NAFTA was initiated was because President Bill Clinton in 1994 saw the European Union as a threat to the Americas. A free trade agreement between the United States and its two neighbors was crafted to be a plausible solution that would offset the growing global economic trading power of the European Union. The implementation of free trade agreements eliminates the imposition of tariffs in the trade of goods. As a consequence of the

The managers used to direct the team as well as support & guide them by teaching them various sales tactics. Handling

Sources of Finance Essay Example for Free

Sources of Finance Essay Finance: Finance is the study of how investors allocate their assets over time under conditions of certainty and uncertainty. A key point in finance, which affects decisions, is the time value of money, which states that a unit of currency today is worth more than the same unit of currency tomorrow. Finance aims to price assets based on their risk level, and expected rate of return. Finance can be broken into three different sub categories: public finance, corporate finance and personal finance. Why Do Businesses Need Finance? Finance is the money available to spend on business needs. Right from the moment someone thinks of a business idea, there needs to be cash. As the business grows there are inevitably greater calls for more money to finance expansion. The day to day running of the business also needs money. The main reasons a business needs finance are to: * Start a business: Depending on the type of business, it will need to finance the purchase of assets, materials and employing people. There will also need to be money to cover the running costs. It may be some time before the business generates enough cash from sales to pay for these costs. * Finance expansions to production capacity: As a business grows, it needs higher capacity and new technology to cut unit costs and keep up with competitors. New technology can be relatively expensive to the business and is seen as a long term investment, because the costs will outweigh the money saved or generated for a considerable period of time. And remember new technology is not just dealing with computer systems, but also new machinery and tools to perform processes quicker, more efficiently and with greater quality. * To develop and market new products: In fast moving markets, where competitors are constantly updating their products, a business needs to spend money on developing and marketing new products e.g. to do marketing research and test new products in â€Å"pilot† markets. These costs are not normally covered by sales of the products for some time (if at all), so money needs to be raised to pay for the research. * To enter new markets: When a business seeks to expand it may look to sell their products into new markets. These can be new geographical areas to sell to (e.g. export markets) or new types of customers. This costs money in terms of research and marketing e.g. advertising campaigns and setting up retail outlets. * Take-over or acquisition: When a business buys another business, it will need to find money to pay for the acquisition (acquisitions involve significant investment). This money will be used to pay owners of the business which is being bought. * Moving to new premises: Finance is needed to pay for simple expenses such as the cost of renting of removal vans, through to relocation packages for employees and the installation of machinery. * To pay for the day to day running of business: A business has many calls on its cash on a day to day basis, from paying a supplier for raw materials, paying the wages through to buying a new printer cartridge. * Special situations: For example, a decline in sales, possibly as a result of economic recession, could lead to cash needs to keep the business stable. Types of finance: It is pivotal to have access to money, in order to start and run a business. There are many ways to get money, all businesses need money. Where the money comes from is known as sources of finance. Now there are two different types of sources of finance: internal (finance from inside the business) and external (finance from outside the business). New businesses starting up need money to invest in long-term assets such as buildings and equipment. They also need cash to purchase materials, pay wages, and to pay the day-today- bills such as water and electricity. In-experienced entrepreneurs (or social entrepreneurs) often underestimate the capital needed for the everyday running of the business. Generally, for every  £1000 required to establish the business, another  £1000 is needed for day-to-day needs. This is why sources of finance are crucial for any business. Internal sources of finance: * Retained earnings: For any company, the amount of earnings retained within the business has a direct impact on the amount of dividends. Profit re-invested as retained earnings is profit that could have been paid as a dividend. The major reasons for using retained earnings to finance new investments, rather than to pay higher dividends and then raise new equity for the new investments, are as follows: a) The management of many companies believes that retained earnings are funds which do not cost anything, although this is not true. However, it is true that the use of retained earnings as a source of funds does not lead to a payment of cash. b) The dividend policy of the company is in practice determined by the directors. From their standpoint, retained earnings are an attractive source of finance because investment projects can be undertaken without involving either the shareholders or any outsiders. c) The use of retained earnings as opposed to new shares or debentures avoids issue costs. d) The use of retained earnings avoids the possibility of a change in control resulting from an issue of new shares. The advantage of using retained profits is that  it does not have to be repaid as in the case of loan while the disadvantages can be that new business or loss making business may not have any retained profits and a business may have retained profits which are too few to finance the expense needed. †¢ Own savings: Personal saving is an advantage for entrepreneurs; this will prevent stress and pressure of gathering money from scratch. Savings can be from previous employments, inheritance, and redundancy. This will be a positive head start for the business and a helping hand also advantage is its interest free. Moreover there is no need to borrow money externally and it is a quick way for the firm to obtain finance. On the other hand savings may be too low to finance the expense needed. †¢ Partnership: This is when two savings is used to help start the business. This is an advantage as there is more money and less pressure. There is a disadvantage for this scheme; sometimes entrepreneurs may fall out over disagreements. * Sale of assets: Some companies often find that they have assets that are no longer fully employed. These could be sold to raise cash. In addition some businesses will sell assets that they still intend to use, but which they do not need to own. In these cases the assets might be sold to a leasing specialist and leased back by the company. This will raise capital and there will be better use of the existing capital in the business. However it may take some time to sell off these assets. * Decrease the amount of stock held: Its advantage is that it reduces the opportunity cost and storage cost of high stock level while a drawback might be that stock level should be kept to avoid disappointing customers. External sources of finance: * Shares: This option is only applicable to limited companies. They can raise finance by issuing shares. Public limited company will obviously be able to raise more finance since it can sell its shares to the public. There are two ways  in which businesses can issue shares. They can either go for a new issue or right issue. Selling shares to a new issue will simply mean that new members will be invited to join the business as shareholders. This method of rising capital can be expensive to organize. In addition the more share sold would mean a loss of control to the original shareholders. A right issue of share is where existing shareholders obtain the right to buy new shares in proportion to their current holding. This will avoid the problem of new shareholders changing the balance of ownership. The benefit is that issue shareholders is permanent source of capital which does not have to be repaid back unlike bank loans while a disadvantage may be that if the business is going for a new issue of shares, it might be costly and at the same time implies a loss of control for the original owners. * Bank lending: Borrowings from banks are an important source of finance to companies. Bank lending is still mainly short term, although medium-term lending is quite common these days. Short term lending may be in the form of: a) An overdraft, which a company should keep within a limit set by the bank. Interest is charged (at a variable rate) on the amount by which the company is overdrawn from day to day; b) Long term loan may be offered at either a variable or a fixed interest rate. Lending to smaller companies will be at a margin above the banks base rate and at either a variable or fixed rate of interest. Lending on overdraft is always at a variable rate. A loan at a variable rate of interest is sometimes referred to as a floating rate loan. Longer-term bank loans will sometimes be available, usually for the purchase of property, where the loan takes the form of a mortgage. When a banker is asked by a business customer for a loan or overdraft facility, he will consider several factors, known commonly by the mnemonic PARTS. Purpose Amount Repayment Term Security The advantage is that it is quickly to arrange and the business can obtain different sums of money, sometimes huge amount which can be paid over a long period of time. However the bank will have to be paid in addition with interest and also banks may ask for collateral security. * Hire purchase: Hire purchase is a form of installment credit. Hire purchase is similar to leasing, with the exception that ownership of the goods passes to the hire purchase customer on payment of the final credit installment, whereas a lessee never becomes the owner of the goods. The advantage is that the firm does not need to pay for the good immediately especially if it requires a huge sum of money while on the other hand interest rate has to be paid and this often makes the goods more expensive. * Government assistance: The government provides finance to companies in cash grants and other forms of direct assistance, as part of its policy of helping to develop the national economy, especially in high technology industries and in areas of high unemployment. For example, the Indigenous Business Development Corporation of Zimbabwe (IBDC) was set up by the government to assist small indigenous businesses in that country. Its benefit is that it does not have to be repaid back and the drawback is that businesses can only obtain help if they follow the conditions attached to it. For example, the need to locate in areas which are poorly developed. * Venture capital: Venture capital is money put into an enterprise which may all be lost if the enterprise fails. A businessman starting up a new business will invest venture capital of his own, but he will probably need extra funding from a source other than his own pocket. However, the term venture capital is more specifically associated with putting money, usually in return for an equity stake, into a new business, a management buy-out or a major expansion scheme. Venture capital firms usually look to retain their investment for between three and seven years or more. The term of the investment is often linked to the growth profile of the business. Investments in more mature businesses, where the business performance can be improved quicker and easier, are often sold sooner than investments in early-stage or technology  companies where it takes time to develop the business model. Just as management teams compete for finance, so do venture capital firms. They raise their funds from several sources. To obtain their funds, venture capital firms have to demonstrate a good track record and the prospect of producing returns greater than can be achieved through fixed interest or quoted equity investments. Most UK venture capital firms raise their funds for investment from external sources, mainly institutional investors, such as pension funds and insurance companies. Venture capital firms investment preferences may be affected by the source of their funds. Many funds raised from external sources are structured as Limited Partnerships and usually have a fixed life of 10 years. Within this period the funds invest the money committed to them and by the end of the 10 years they will have had to return the investors original money, plus any additional returns made. This generally requires the investments to be sold, or to be in the form of quoted shares, before the end of the fund. * Borrowing from friends and family: This is also common. Friends and family who are supportive of the business idea provide money either directly to the entrepreneur or into the business. This can be quicker and cheaper to arrange (certainly compared with a standard bank loan) and the interest and repayment terms may be more flexible than a bank loan. However, borrowing in this way can add to the stress faced by an entrepreneur, particularly if the business gets into difficulties. *Trade credit: By delaying the payment of bills for goods or services received, a business is, in effect, obtaining finance. Its suppliers are providing goods and services without receiving immediate payment and this is as good as `lending money`. Its advantage is that it is an interest free of financial rate. However the suppliers might not agree or even refuse to supply the goods in the future if ever payment is not made quickly. * Leasing: It is where a firm can use an asset without the need to purchase it. The advantage is that there is no need to find large sums of money to purchase the asset and care and maintenance of the asset is the responsibility of the  leasing company whereas a disadvantage might be that the total cost of the leasing charges may be higher than purchasing the asset. * Factoring debt: Debt factors are specialist agencies that buy the debts of firms for immediate cash. However they will only give the company selling its debts 90% of the existing debts, the remaining will represent the factor`s profit. The benefit is that the company selling is debts will obtain immediate cash and the risk of collecting the debt is transferred to thee debt factor. On the other hand, the firm selling its debt does not receive the total value of its debts. Factors to be considered when choosing sources of finance: When a firm needs finance, it becomes crucial to pick how much finance they need and for how long. It can ruin or make a business. A firm will have a wide range of sources to choose finance from such as a bank loan or overdraft, share capital, venture capital, profit, or trade credit. However, some sources of cash are suited best for short term while others are best for long term and some are suited for little injections of cash while others are suited to huge injections of cash. Before a business decides what source of finance it should choose, they need to ask the question: * How Much Finance Can the Business Obtain? * The type and amount of finance that is available will depend on several factors. These are as follows: The type of business a sole trader will be limited to the capital the owner can put into the business plus any money he or she is able to borrow. A limited company will be able to raise share capital. In order to become a public limited company, it will need to share capital of  £50,000+ and a track record of success. This will make borrowing easier. The stage of development of the business a new business will find it much harder to raise finance than an established firm. As the business develops it is easier to persuade outsiders to invest in the business. It is also easier to obtain loans as the firm has assets to offer as security. The state of the economy when the economy is booming, business confidence will be high. It will be easy to raise finance both from borrowing and from investors. It will be more difficult for businesses to find investors when  interest rates are high. They will invest their money in more secure accounts such as building societies. Higher interest rates will also put up the cost of borrowing. This will make it more expensive for the business to borrow. These factors will help make the firm decide how much it needs or can borrow. So, at this stage the business knows how much it needs and in the space period it needs it for. Here are the most logical solutions to sources of finance for short/long term and high/low finance: * Amount needed: * Shares issue and sales of debentures, because of the administration and other costs, would generally be used only for large capital sums. * Small bank loans or reducing debtor`s payment period could be used to raise small sums. * Cost: * Obtaining finance is never free, even internal finance may have opportunity cost. * Loans may become very expensive during a period of rising interest rates. * A stock exchange flotation can cost millions of dollars in fees and promotion of the share sale. * Legal structure and desire to retain control: * Share issues can only be used by limited companies- and only limited companies can sell shares directly to the public. Doing this runs the risk of the current owners losing some control – except if a right issue is used. * If the owners want to retain control of the business at all costs, then a sale of shares might be unwise. * Size of existing borrowing: * This is a key issue- the higher the existing debts of a business (compared with its size), the greater the risk of lending more. Banks and other lenders will become anxious about lending more finance. * This concept is referred to as gearing. * Flexibility: * When a firm has a variable need for finance- for example, it has a seasonal pattern of sales and cash receipts- a flexible form of finance is better than a long term and inflexible source.

Marketing Is A Performance Of Business Activities Marketing Essay

Marketing Is A Performance Of Business Activities Marketing Essay 1. Marketing is a performance of business activities that direct the flow of goods and services from produces to consumer or user.(AMA 1960) In a modern world definition like Marketing is one of the most important terms in Business environment. Especially well structured Marketing is aim which all over the world strongest companies demanding to get. Only successful Marketing can identify most important fragments which company require for good recoupment of the capital investments. All the businesses have their own business plans and strategies as the rule of that Marketing has its own strategy which usually well structured and its organization and structure created on a basis of particular commerce. Creating such a strategy has to be made step by step. Analysis of marketing environment and definitions like PEST and SWOT and their role in collecting data for developing marketing plan is crucial important. External and internal factors, which can relate with specified area and can effe ct on sales of company is very significant. And collected data can be basic of strategy and it can be support for further research. Significance of collecting primary and secondary data is one of the delicate factors on the way to superior Marketing strategy it has be accurate and effective for specified issue. Finding required market for concrete product by Segmentation (demographic, geographic, psychographic, behavioural) lies in the fundamentals of creating Marketing Company. From all the types of segmentation has to be selected the correct individual for using in actual Marketing Strategy. All of this process of identifying market is the approach of environmental investigation and is the element of data collection. Extremely important to analyse ground rules like auditing, and capability of the company, productivity and ratio analysis, market and environmental analysis, customer and competitor analyses. Also in a creating Marketing strategy communication linking market and compa ny one of the unavoidable factors. And to opt the right method for each communication circumstances is important for successful and comprehensible transferring data. Well organization and accuracy one of the core rules of business and any planning. Well planned and construct marketing plan can predict sale`s, find public of store and its place of further demand. Achievement of success in Marketing deepens on collecting secondary data, created primary and using all of those in acceptable way. Our company is a large mobile phone producer has decided to develop a new range of hi-tech mobile devices for young professional market. In order to promote this new range, we must understand the current `prevailing climate` in the external environment. I will develop a report for the company advising what is happening in the world that impact on its industry. 2. Company X is one of the popular mobile phone device producers in the world nowadays. Company has big stores in the central cities like London, all over the world and which has a good reputation belong the people with different lifestyle because of the large arrangement and difference of mobile devices. Over the years company developing different types of mobile phones for individual groups of people by taking into concern their life style and requirements. Analysing the environmental factor helps a company be a leader of the sales since many years. During making various Marketing campaigns Company always tries to satisfy needs of consumers including all aspects like Social life techno progress nowadays in the world and keeping under attention the Economical situation in market and their possibility to by goods of Company. And in a process of building this marketing campaign will be included all the preference of specified area of market. Identification PEST and SWOT analysis. What is the PEST and what is the SWOT? PEST it is the external factor, external environment, macro environment which at first look does not effects to the company but which can react on the market. It is Political, Economic, Social and Technological situation in the world. And the SWOT is the internal micro environment of the company its customers, employees and competitors. PEST and SWOT Analysis of influences in the external environment POLITICAL/LEGAL ISSUE Taxation policy Monopoly controls Environmental protection measures Employment Law Environmental legislation Foreign trade agreements Stability for the governmental system ECONOMIC FACTORS Interest rates Inflation rates Money supply Business cycle Unemployment GNP trends SOCIAL/CULTURAL ISSUE Age profiles Social mobility Changes in lifestyle Family structures Level of education Work behaviour Leisure activities Distribution of income Patterns of ownership Attitudes and values TECHNO FACTORS Focus of government research Rate of technology transfer Materials Developing technological proceses (Strategic marketing planning and control Graeme D. John E. ) By taking in to a mind that our company is establishes in UK we have to start research of macro environment of the country and define how these factors can effect on mobile phone industry. UK has monarchy government and its parliament with its liberal and conservative parties nowadays liberals are dominant in the government and the political situation in the country stable. UK always had good neighbourhood relationships with the other European countries. Even the political situation is constant the economy of the country is steel weak after the credit crunch which had a place in 2008.Nowadays country in a stage of recession and the economic norms on its attempts to come back to the norm. UK is multinational country, millions of people every year visiting country or coming to study. That why the cities are always busy and crowded. There are not much industry services in the country and manufactures takes leading place. If to talk about the technology progress of the country it wont be surprise that the first developed, discovered and created modern techniques comes and produces in the country very fast and people use to this progress and always trying to find the best and modern technologies in the stores. In process of making research of the PEST I appeal to the sources like internet newspapers articles and official financial indexes. In a process of research figures of the opinion poll will clear show the preference of young market. By public requirements has to be created the mobile phone devise X phone. During the 1 month time mobile phone has to be tasted by focus group (focus group is one of the ways to collect primary data by giving to the special chosen group of people samples of product and ask them their feelings about it). In the summary of the marketing company has to be taken into consideration feedbacks of this focus group. 3.Now when the secondary data collected and when the elements of primary data is ready and viewed it can be considered that the raw data is collected and the final step is to summarise research and make deduction. On the basis of our quantitative data and raw data has to be made qualitative. First as the statistics shows the most of the population of UK is young people, the politic situation in country dont react on the sales in the future, even economic situation is unstable market still can afford to by our product.. Also made research confirms that if mobile devise will be on the sale in any stores of the UK the demand of it will be very high because of the majority young population of the UK will prefer made devise. The most appropriate way to make advertisement for the devise founded city newspapers as most spreading method of advertisement and it will be most visible for the market.

Anti-cancer Drug Targeting AFR Receptor

Anti-cancer Drug Targeting AFR Receptor Results 1a 1b Figure 1 Cell viability data based on the use of the XTT assay Two different lung tumor cell lines were tested: one expressing the mutated AFR receptor (blue line) and one that expresses wild-type AFR (orange line). Figure 1a represented AFR lung cancer cell line with Drug X and figure1b represented AFR lung cancer cell line with drug Y. Cells were seeded in wells of a 96 well plate at 3 x 10*4 cells/well before treatment with the drugs at the indicated concentrations for 72 hours (triplicate samples at each concentration). XTT assay reagent was then added to the wells and the absorbance measured at 450 nm. Control wells (no cells) contained medium but no cells. The Cell Proliferation XTT assay is a colorimetric assay for the nonradioactive analysis of cellular proliferation, viability, quantification of cytotoxic and cytostatic compounds like anticancer drugs and pharmaceutical compounds, evaluation of growth-inhibitory antibodies and physiological mediators that able to inhibit cell growth (Sigma-Aldrich, 2016). Sample is adherent or suspension which cultured in 96-well microplates. A fictional receptor (AFR) was targeted by anti-cancer drug to inhibit the mutated AFR function, causing an anti-proliferative effect and even cell death. XTT ((2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide)) assay was used to measure cell viability in the two different lung tumor cell lines, one expressing the mutated AFR receptor (AFR mut) and one that expresses wild-type AFR (AFR wt). Drug Y was observed to hinder cancer cell growth dose dependently (Figure 1). The amount of observed absorbance increases with cell number and incuba tion time for 72hours when a maximum absorbance level is reached. The plot of the XTT assay data should create a curve with a linear part. This area exhibits the highest sensitivity to changes produced by the experimental parameters. Establishing the XTT assay data for treatment of AFR mutated and AFR wild-type lung cancer cell line with drug X from 0nm to 1600nm (Figure 1a), It was illustrated that the cell viability of mutated AFR increased considerably from 1.1 to 1.3 between 0nm and 800nm and then became steady at approximately 1.4 from 800nm to 1600nm. Compared with the wild type of AFR (Figure1a), the trend of the line was similar to the mutated one but the cell viability was first rised from 0.9 to 1.2 between 0nm and 800nm and finally exhibited a loss of linearity when greater than 800nm. The lung cancer cell line with drug X represented a cell proliferation assay because the absorbance values of the mutated one were greater than control conditions, representing an increase in cell proliferation and viability. On the other hand, investigating the XTT assay data for treatment of AFR mutated and AFR wild-type lung cancer cell line with drug Y from 0nm to 1600nm, It was indicated that the cell viability of m utated AFR started off at about 1.1 from 0nm to 50nm and then occurred a dramatic drop from 1.1 to 0.1 between 50nm to 400nm and finally lied on 0.03 at 1600nm (Figure1b). Compared with the wild type of AFR (Figure1b), the line was also decreasing but showed a completely different trend. The cell viability decreased from 0.89 to 0.88 between 0nm and 800nm stably and then exhibited a significant drop when greater than 800nm and finally lied on 0.8 of 1600nm. The lung cancer cell line with drug Y represented a cell apoptosis assay as the absorbance values were lower than control conditions, showing a decrease in cell proliferation and resulted from cellular necrosis or apoptosis. From the data analysis, drug Y was successfully tested to inhibit the function of mutated AFR which have an anti-proliferative effect to cause cell death and drug Y could be put forward for further testing. Figure 2 Flow cytometry apoptosis data: Annexin V -FITC (x axis) and propidium iodide (Y axis)   Ã‚   The proapoptotic effect of drug X and Y. The AFRmut cell line was treated with each drug at a concentration of 800 nM for 24 hours. The cells were harvested, resuspended in buffer and then treated with Annexin V-FITC and propidium iodide. Cytograms of annexin-V-FITC binding against PI uptake show three populations: (i) viable cells (low FITC and low PI signal) in gate Lower Left; (ii) early apoptotic cells (high FITC and low PI signal) in gate Lower Right and (iii) cells that lost membrane integrity which results in late apoptosis (high FITC and high PI signal) in gate Upper Right. The percentage of cell death increases in the tumor cancer cell line of drug Y, as demonstrated by incorporation of Annexin V. The inhibition of cell proliferation caused by AFRmut was related to the apoptosis induction. Apoptosis is programmed as cell death which is important in development, in normal function of certain tissues and in the response to the damage. Apoptosis involves events which results in the destruction of cell. Annexin V -FITC is a protein that binds to phosphotidylserine which can be labelled and used to detect apoptotic cells. The flow cytometry apoptosis data was plotted on a dot plot and the lower left was represented the viable cells while the upper right and the lower right were represented the dead cells and the apoptotic cells respectively. From the apoptosis data (Figure2), it was observed that the untreated condition showed 77% viable cells and 21% of apoptotic effect. When AFRmut was treated with drug X, the viable cells were increased by 19% and the apoptotic effect was largely decreased to 3%. In contrast, the incorporation with drug Y lead to considerable anti-proliferative effect where 58% of apoptotic cells were observed and viable cells only remained as 40%. Related to the induction of programmed cell death, the majority of cells from the two tumor cell lines were alive upon carrier treatment, the use of AFRmut lead to the entrance of these cells into apoptosis with incorporation of Annexin V. The treatment of drug Y showed a significant apoptotic effect than the drug X, which has a potential to inhibit the function of mutated AFR and results in anti-proliferative effect. Figure 3 Flow cytometry cell cycle data: x-axis shows propidium iodide fluorescence and y-axis shows the number of cells The AFRmut cell line was treated with drug X and Y at a concentration of 800 nM for 24 hours and then fixed with ethanol and stained with propidium iodide before analysis in a flow cytometer. Treating with drug Y showed no cells in G2/M phase. The inhibition of cell proliferation induced by AFRmut was correlated with cell cycle which was evaluated with propidium iodide by flow cytometry. Cell cycle demonstrated the cell progression through a division cycle which result in cell growth and separation into two daughter cells. Live cell observation of cellular DNA and distribution of cell cycle are valuable to regulate apoptosis, and also the tumor behavior and suppressor gene systems. Cells would be distributed into three phases of cell cycle: G0 /G1 phase (2N), S phase (DNA synthesis with various DNA), and G2 /M phase (4N) to identify apoptotic cells with partial DNA content desirably   (Krishnakumar R, Kraus W ,2010). Propidium iodide fluorescence was needed in these actions to bind DNA. From the flow cytometry results by histogram (figure 3), the untreated condition showed 42% of cells in G0/G1 phase while 31% in S phase and 27% in G2/M phase. When the AFRmut was treated with drug X, the cell number in G1 phase dropped by 7% while there was increase of 6% in S Phase. DNA replication occurs more effectively during S phase. Tumor cells with a higher proportion of cells in S phase as tumors were growed faster and more aggressive in that phase so drug X induced proliferation of mutated AFR. However, the addition of drug Y caused effective anti-proliferation effect by increasing the cell numbers in G1 phase from 42% to 86% since the cell has left the cycle and has stopped dividing. There was increase in the cell numbers and grow in size. The decrease from 31% to 14% for S phase indicated the ineffective DNA replication. Moreover, there was no cells observed in G2/M phase when treated with drug Y which represented the increasing numbers of apoptotic cells and the G2/M pha se arrest, which failed the mitosis progression. Discussion Drug Y can be an effective anticancer drug which targets mutated AFR and inhibit its function to lead an anti-proliferative effect. In the present study, two lung tumor cell lines, mutated AFR receptor (AFRmut) and wild-type AFR (AFRwt), Drug Y was found that it could inhibit the growth of the AFR in vitro. The IC50 values of AFRmut and AFRwt were with the same range of 450nm. Additionally, the cell cycle revealed that Drug Y arrested mutated AFR at S phase and G2/M phase. Furthermore, the data demonstrated that Drug Y induced apoptosis in the mechanism assessed by 3 different methods: cell viability assay, apoptosis assay and the cell cycle of flow cytometry. Taken together, these results suggest that the inhibitory effect of Drug Y on cell proliferation in mutated AFR is mediated through induction of cell cycle arrest and apoptotic cell death. The limitation is the flow cytometry are only authorize the relative abundances of cell cycle phases compared to another (Dick FA, Dyson NJ, 2002). These actions can be examined by evaluating a coordinate sample of cells with mitotic inhibitor like nocodazole or G1/S inhibitor like aphidicolin. As these drugs establish a prevalent arrest in M-phase or early S-phase accordingly, moderately proliferating cells will gather at the drug inferred arrest location. For instance, cells arrested in G1 BY pRB expression will stay in G1 phase regardless of nocodazole treatment even regulating cells will accumulate in M-phase[13] Overall, the data demonstrated drug Y is able to develop an anti-cancer drug that targets a receptor called AFR (A Fictional Receptor) to block its activity. Drug Y successfully inhibits the function of mutated AFR by evaluating the cell viability assay, apoptosis assay and the cell cycle of flow cytometry. The assays showed an anti-proliferative effect and even cause cell death, which explains its significant antitumor activity in the various experimental investigations that have assessed. Thus, further studies about the way of administration, dose limiting toxicities and recommended doses are needed for the preclinical development of drug Y to evaluate the potential of the compound as an anticancer drug.

Mary Whiton Calkins Essay -- essays research papers

Mary Whiton Calkins was the first woman to be elected as president of the American Psychological Association in 1905. The majority of her adult life was dedicated to her work in the development of â€Å"psychology of selves.† She was very passionate about the relatively ‘new’ world of psychology and was highly active in the field of philosophy. Mary Whiton Calkins was not deterred in her ambitions because she was a woman, instead she used her struggles to gain a voice and to speak out against the oppression of women during the 1920’s.   Ã‚  Ã‚  Ã‚  Ã‚  Born in 1863 to a Presbyterian minister and his wife, she grew up in a very tight-knit family as the oldest of five children. In 1880, the family moved to Massachusetts where they settled and built a home. Mary’s father wanted the best for his daughter, and designed and supervised Mary’s education until she graduated in 1882. Upon graduation, Mary attended Smith College with an advanced standing as a sophomore. In 1893, Mary’s sister passed away and Mary dropped out of college for a season, taking her classes through private lessons at home. Mary returned to Smith College in 1884 as a senior and graduated with a concentration on philosophy and classics. In 1886, two years after graduation from college, the Calkins family went to Europe for a holiday that lasted for sixteen months. Mary continued to expand her knowledge of the classics and upon returning to America, her father arranged an interview with the President of...

Essay on Toni Morrisons Beloved - Freedom and Independence

Freedom and Independence in Beloved  Ã‚      Toni Morrison’s important novel Beloved is a forceful picture of the black American experience.   By exploring the impact slavery had on the community, Beloved evolves around issues of race, gender, and the supernatural.   By revealing the story of slavery and its components, Morrison declares the importance of independence as best depicted by Sixo.   The combination of an individual amongst a community sets forth the central theme of moving from slavery to freedom and reconnecting with family and community. Sixo is one of the nine slaves living on Sweet Home, a Kentucky plantation.   A young man in his twenties, Morrison introduces him as â€Å"the wild man† (11) without explanation.   Later, Paul D describes Sixo as â€Å"Indigo with a flame-red tongue† (21).   He is closer to the African experience then the other slaves.   Morrison portrays Sixo as the odd man out in an attempt at underlining the idea of an individual in a community.   Community at Sweet Home is the only reassuring object possessed by the slaves.   The relationship among fellow slaves creates a â€Å"mock† community, which is enough to satisfy everyone.   Morrison utilizes Sixo as rebellious and clever, one who refuses to conform to his predicament.   Physically a slave, Sixo rejects his position and remains a spirited man who takes night walks and dances among the trees to keep his bloodlines open.   Although black sexuality is dominated by slavery, he chooses his own woman and controls his own destiny.   Sixo â€Å"plotted down to the minute a thirty-mile trip to see a woman.† (21) Despite the bounds of slavery, Sixo asserts his independence and searched for a better life and family of his own.   In an attempt to free himself from the restrai... ...Sixo’s characterization defines how slaves managed to remain people despite slavery.   Morrison places Sixo in the novel Beloved, to express the manifestation of community as well as individualism.   Sixo uses the strengths of the Sweet Home community to independently search for an identity of his own.   Without the consistent community of Sweet Home, Sixo could not of ventured upon journey after journey in search of personal freedom. The steady community enabled Sixo to express a rebellious independence, that otherwise would have been lost.   Sixo maintained a sense of self, lost by many others.   Beloved explains that the independent spirit and the belief in personal self worth can not be maintained without the presence of an impermeable community, and the individual desire for freedom.

Water and Womanhood in Ancient Greece Essay -- Women in Marine Mytholo

In the times of ancient Greece, there were ample tales, myths, and legends surrounding the realm of the sea; many of which included fearsome beasts, epic struggles, and angered gods. There are tales of vengeance, spite, cruelty, and rage, but there are also those of understanding, compassion, helpfulness, and benevolence. When one subjects many of the more malevolent (and sometimes disturbing) tales to closer inspection, it becomes fairly evident that a great number of these stories use a feminine force in order to display the wraith of the sea and the sea gods or goddesses. In fact, many sea monsters are said to be female including Charybdis and Scylla (the horrors between which Odysseus and his crew must sail through the Strait of Messina), and the sea was often given a female personality and character traits. Ceto, particularly, was the feminine embodiment of the dangers which the sea held, and Amphitrite was one other powerful, feminine sea goddess. The connection between terrors of the sea and the female persona may not be presented with the utmost clarity right away; however, it is possible to use symbolic history, cultural normalities of the time, and a brief glance at the ancient Greek view of sexuality to help discover these mysteries. Symbols for water and womanhood have been known to coincide greatly, essentially since the beginning of the history of recorded symbols. The inverted triangle was an especially prominent emblem when it comes to this matter, as it was used to represent both the flow of water (or sometimes a cup, or chalice), as well as the shape of the female reproductive organs and genitalia. These similarities were not contained only to written symbols, but to rather more abstract symbolism as well. O... ...tainly made theirs far more interesting than many other cultures.

Thru this journey, Everyman sees his friends and brothers on earth flake out and fade away.His friends, the ones Everyman thought were so good and important to himthey leave him aban dressed, alone, at the side of lifes road in the end. He must have looked like a hooker on sunlight morning. As Everyman faces each friend and companion leaving him, he calls, victimisation his Verizon phone, on one of his last resorts as a friend, life-threatening workings. Good Deeds is very physically weak, like a tweeker, be sustain Everyman has non done m any good kit and boodle in his life time. She is the equivilant to a see whore. Good Deeds asks her sister, fellows rose hip, to go with Everyman as he travels.Knowledge, as the name sugge sts, is undimmed and wise in the ways of the world, For snizzle. Knowledge takes Everyman to Confession, in a Catholic like ritual, not that I am a fan of Catholic rituals after ceremony Stigmata on DVD or anything.. afterwards regaining some strength, maybe they use human growth hormones. Good Deeds joins Everyman on his journey, they share a doobie and walk of life on. Everyman arrives at his death, the grave. he shit his knickerbockers after he Lost his friends, Wits, dish and vividness, he only can take Good Deeds with him to heaven.He realizes all that money he worn out(p) on getting high on life was a total waste of money. At the end of the play, the character of the Doctor (may be a proctologist) comes into the frey, he gives advice to the au ceasence, a terminal closing comment to be interpreted to heart, Take it of charge, young and old, and forsake primp for it deceiveth you in the end, and remember Beauty, Five Wits, Strength and Discression snizzle my nizzle. They all at the last do everyman forsake, save for his good deeds in that respect doth he take. (Anonymous, 902-906). Everyman 4. The conditions experience of an inevitable death.The reason, anonymous, as he or she may be, has been lost in time. So they dont get any credit for all the time they spent writing this crappy play. He, or she, uses great and wise insight in using his characters names to show the reader, or watcher of the play, that Everyman is subject to death just like anyone else. As Snoop Dog says, Wez all gotta die, suckers. The author pulls the audience understand that any human is not able to trip out death no matter how substantial they return, or how much money they have in the bank.The author does a mulct job using words to characterization Death as being anunder rest, long-suffering character, although Death should have been a creature from Aliens, that would have made the play more interesting. The author makes his catamenia clear that death does not spare the rich or the poor, the officer nor the gentleman, nor the wise or the foolish. The journey to death is one we will all have to make on our own, and approximately likely one we will make alone, cause we cant take all this shit with us. The author puts emphasis on Everymans refusal to go to his death willingly. Everyman was not properly prepared to go on this journey, he had yet to hire an attorney.This reflects the predilection that no human is given the bring time of his or her death, so we all must be ready to die at any time. We are warned to have our shit and stuff in order. exclusively of the assorted characters in Everymans life, his questionable friends are the authors representations of characters we humans have in our lives. The author makes a pinnacle head that the character, Death, answers to Gods beckoning or his will. It is God, not Death that decides netly who dies when and where its not if you get hurt, its when and how bad.Death is just the messeng er, so dont go shooting the messenger. The author puts value on what happens when anyone, or Everyman, dies. The author also points out the things that everyone will leave behind, for the relatives to fight over. Courage and wisdom is use To persuade Everyman to continue to move towards his ultimate goal of death. The author made a simple understanding of making for certain that everyone does good deeds while they have time on earth. Practicing random acts of kindness, property the toilet seat down, and doing good deeds will help ones case when standing before God in judgment.All throughout the play uses the now notable stages of death and denial found in the book, Psychology, By D. G. Myers. Myers defines denial as, A apology mechanism by which people scorn to believe or even to perceive painful realities. (Myers pp. 558). Everyman has to come to terms with his own impending death. The author gives Everyman Knowledge as a companion for his death tour. This helped Everyman loo k a death a little differently, and helped him face up to his death, and to the truth about his fading group of friends, his gang sucked for sure.The author puts importance on Everymans act of confession and penance, and gives him credit for not draining Ax deodorant spray cause that crap stinks. The character, Good Deeds, once mold and weak, apparantly addicted to meth or crack, becomes stronger in time after a scant in rehab. The author made his point that one cannot get into heaven by doing good deeds alone, but by accepting Jesus Christ as savior, or whatever god is hip at the time, with saving grace gainful for ones way into heaven.On critic and author stated about the plays end, Good Deeds weakness demonstrates that Everymans the character good works cannot merit redemption when he is guilty of unforgiving mortal sin. Onlypenance will recover him to a state of grace, revive Good Deeds the character, and make Everyman ready to translate an account of his life before God . (Paulson, 2007). Conclusion, and try not to copy my work word for word, dumbass. Everyman the morality play, once called, The Summoning of Everyman (Anonymous, 114) is a simple tommyrot about making amends in their life before its too late.Our treasures, our bling, real or imagined, here on Earth are not worth dying for. The promise is found in the Bible in Matthew 53, God blesses those who realize their need for him, for the kingdom of nirvana is given to them. (New International Version, Student Edition). unrivaled should try their best to live a good, holy life, have faith, worship God, dont knife your friends, and practice good deeds to be ultimately rewarded with an futurity with God in the Heavens. And then you can party like its 1999. If you can remember that far back. Bibliography Allegory.(2010).

Effects of Computers and Technology on Society Essay

The development of office figurers in be recentlydly 70s has necessitate a major breakthrough in our present guild. Although the earlier computers were custom solely for the purpose of bear on and transmission system military data, the realization on the intent of computers bear f all in all(prenominal) out the office computers we catch today. Office parturiencys pack never been easier since the computers realise been dedicated to complete such immense and taxing phone lines in data processing. Since then the work loads particularly in the office be turn out sour borderline and little stressful for the employees.Suddenly because of our innovativeness we began to explore to a greater ex xt and contend up with more forward-looking computers we use today. The earlier versions of computers were less-traveled because they argon bulky and with heavy features which makes them conflicting for small offices. Thus most of them be installed on laboratories and engine ering d hale. As computers proceed to be innovated, their sizes turn in been greatly rock- come home but they ar in a flash scurrying and more reliable. They endure instantaneously be utilise for word processing which is a really essential in processing documents.In the mid-80s the dimension of the computers continued to be lesser into portable desk make its and brook now be placed on top of office tables. Indeed they now evolved to be more compact, lighter, faster and more tendinous. They groundwork now run multiple programs and softwargon intersection point at the same time. Then in the 90s the maturate of the meshwork has arrived. From the conception of plyful computers now comes the most utile means of transferring data and substances all over the domain. hither(predicate) is the now the raiseation of the World across-the-board Web or the internet.The lucre has positive into 1 of the most powerful specialty for universal communication, mode of t raining provider, high look for electronic transactions and most favourable reality-made lake for entertainment. The net income link computers by phone lines and high speed digital lines which ne tworked all computers that ar spread out around the world. applied science which brought up the ruse of the computer and the internet has made everything possible. We drive improved a pretend by leaps and bounds.The Internet as todays most ingenious form of applied science has greatly influenced our lives. We plunder now remark jobs notwithstanding by browsing the Net, discover movies from different websites, search for boththing and everything that is beyond our imagination, source out training on any subjects and withdraw transactions with other plurality around the globe. It is now so slow to send messages just by typing our texts using our email address and with a click of a button tramp send the message to other emails. Transferring the message may just nominate some seconds.A nonher example to prove the cogency of the Internet argon the chat rooms that tooshie transfer bulk of messages and pictures in seconds at the same time. These atomic number 18 just few but most usable contributions of the engineering science we use today. Since the Internet has become the highway for the largest and widest medium of communication and information exchange, business transactions and on-line granticraft claim developed into the most habitual method in business operation. The largest online deals in the world such as the Stocks deputize and the Foreign Exchange currency traffic swear on the Internet to conduct business.In line with this engine room, the computers, however, to a fault became sophisticated and powerful to gondolary on the task of processing data and information light speed times better than what ordinary computers sight do three decades ago. To frank and comely this is what heap wish to invent and localise on techn ology to make things lot easier for us. veritable(a) ordinary house chores be now performed with the aid of the machines. We induct invented lavation machine, the dishwasher, the floor polisher, the air-conditioning system and the television for our entertainment.How grand it is to live in a world well(p) of magic brought about by the gadgets, machines and equipment we make. yet after all of these abominable things nominate been invented did it benefit the order in world-wide? It is true that the inventions of machines have made things lot easier, faster and more precise. exclusively do you know that since technology has greatly improved, millions of jobs have already been lost because they have become obsolete? As we foster in our proximo and develop more technology thither is besides fracture of man with their profession. We use to power everything by hand then by the machines and now by the computers. wherefore would manufacturing companies hire takings communi ty if they apprise mechanize and provide every process in their factories? Why would car makers hire muckle for car assemblies where they terminate buy machines that ar programmed and automate? Machines does non take their break, do not complain about abuse and no need for any insurance? ostensibly because of our technology, people are get phased out of their circulation and depriving them to gull their maintenance. The computers, the Internet, the game gadgets, carrell phones and accessories have to a fault loosen our blot with the reality thus our bond with our families are also affected.The realization of the technology which has widened mans contact into the out font world has in a way contain him to smaller virtual world that rely on technology alone and not on physical attributes (Ghimire 2006). On the side of the economy, however, the negative impacts are obviously caused by the advancing technology. It is true that many people preferred engaging on technolog y-based education have benefited with the continuing wind in science. But what hazarded to those who did not earned peaks or does not have knowledge with the trend? How can they cope up with the world that is being run by this technology?Would they remain to be at the bottom of the ladder because the skilled people take all the best opportunities? Since the early 70s, computerization started to liberalize workforce, American workers with non-degrees begin to finger the squeeze. This is because the technology has started to manage the world in a more synchronized and automatise manner. The most favored jobs have false the table in favor of the ameliorate and the skilled. To cope up with the development, courses in sexual congress to technical skills, computer and software engineering and programming were offered.Today, the people who dominate the highest income brackets come from among those who specialize in this field. The jobs for the recreational have become leaner and the demand for their work was greatly reduced making them poorer, imbruted and unfit for employment. check to L. Mishel, Director for look for on Welfare Reform Network, the hazard on the development of information age is that small-arm the technology can step in workers with cheaper cost, this trend might become dangerous with the economy because in that location volition not be nice purchasing power to push the economy onward magic spell we lead our lives into the future.To ease the effect of technology on people, Mishel suggested that at that place must be political action to make social evolution beneficial to everybody (Smith 2007). But although the technology has affected those who are untrained, the computers and the Internet have produced a digital world of information and accessibility. Almost everybody can now turn over out to the Internet. You only have to go online to order goods, books, clothes or thus far groceries and it will be delivered directly to you.The Internet also benefits the older people because they can now email people they want to get in touch with. If you happen to feel sick and want to halt for yourself about the symptoms you have you can die from the Internet to avoid health hazards. Moreover, the computers and the Internet have created a world full of opportunities. Jobs are being created and obtained everyday because there are always new jobs come in the Internet sphere. This is especially beneficial for those who have skills with regards to Information Technology.Based from the 2005 2006 National railroad tie of Colleges and Employers, the regular computer engineer can earn more than USD53, 000 a form for their first year of employment while the entry level management can make up to USD 38,000 as well. correct small businesses have greatly benefits from this technology. descent proprietors can now advertise their product through many websites and can invent employee schedules with programs like Micro soft Excel. There are also online educations today that many universities offer and the opportunities are get larger.It is projected that by the year 2009, one in every ten students will be enrolled in an online degree program. However, there are always dis favours from the advantages. at one time the backlash from this advantage does involve encounter with every person registered on the Internet. indistinguishability theft has always been the number one crime in the United States. Although programs are constantly created to protect users from Internet hackers and scammers, there are also lots of experts who use their knowledge to commit fraud in their favor. Billions of dollars are being stolen because of identity theft, scams and online fraud. unluckily only few of them are get caught and usually the discovery was too late before the harm has been done. Even the movies and TV series which are supposed to be legally shown only on cinemas and televisions are also being shown on the Internet without proper license and agreement with the producers. lately the Writer Guild of America demanded payments from the owner of the domains. In effect, the rights of producers, TV stations, actors and actresses are violate and the chances to earn from these shows are lost.Sadly as the worlds of computers are here to stay there are always dangers in getting scammed in every step of the way (Weidenfeld 2008). And so as the technology changes in its fast paced environment we, as users also changes as well. Lets just hope that we could always cope up with any changes that the age of information and technology can bring us. There would be transformation and modification, of course but with less time to prepare we may credibly make the wrong choices and our technology point it was intended to develop can abrogate us (Graves 1990).Summary Computers and the Internet are two of the most brilliant discoveries of man. look has never been easier with their aid. Computers are th e most used and essential equipment in the office or even at home. Everybody almost have it because of its functionality and usage. The Internet on the other hand has succeeded in building gaps between people, races and cultures and provides us the opportunities to explore all things that exist here and beyond our world.But while we are joyful of the benefits of these forms of technologies not everybody is at their advantage. From the very first introduction of computerization, the untrained and the artless began to feel the hardships of being uncompetitive. The technology has created jobs tally to its own trend. If you are unskilled and wants to earn a decent living you have to sweat it out to and can be able to earn minimum pay while the new generation of computer experts enjoy their chances in their virtual world.This is the general belief of some observers. Analysis According to the points presented, there are always advantage and disadvantage at any normal discoveries of ma n. Man is a very convertible creature and he makes discoveries harmonise to his needs. The Internet and the computers have naturally eased up our burdens with our jobs, communication and commerce. But with this technology there is the theory that lots of people politic blame technology as the culprit in decimating their chances to be competitive.Accordingly, people living on rural societies as well as the older people and the unskilled feel that they are always go forth out with the technology making them befuddled and useless. But my personal opinion relies not how quantitative the advantaged of technology to most people but how the technology could benefit all people in any society. Technology does shape our future but our future depends on every fiber in our society which means that the people alone are shaping the future not the technology.Technology is merely the product of our modernisation and innovation that is continuously taking us higher to new realities and develop ment. But we lest not forget that technology can also be erased, altered or reprogrammed because the society is making the technology themselves. However, the complexities of the issues discussed here is that has the introduction of the computers and the Internet really affected our society in general? True enough the untrained and the uneducated can honor it hard to participate with the virtual world.But does technology was created to rationalize people according to their capabilities? I think not. Whether we like it or not our technology with computers and the Internet will continue to advance and so there are no chances in handout back to pick those that have been left-hand(a) out. There are always two sides of the coin here. It is up for the people to choose. If we are people with strong mind and absorb to cope up then we can be able to discover how rattling(prenominal) the technology can bring. Computers and the Internet are not complicated, adaptable, beneficial and educa ting people continuously. whatever jobs and opportunities you wanted can be found in the Internet regardless of what you can do. Just look around and observe. Even children, the elderly and disabled people can benefit from the technology. Education, jobs, opportunities and communication is now sceptred by our technology. The old days of manual of arms labor is almost over. We invent things to make things easier and there is nothing wrong with doing the job the easy way. If there are people who are against of this technology it maybe because they are closing their mind with it.The Internet offers all kinds of prospects in learning, opportunities and information. It is only right that we have to take advantage everything that it offers because for sure we would by all odds grow with itReferencesGhimire, Shakti. 2006.

Advances in Modern Irrigation Systems Essay

ABSTRACTIrrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, management, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops.The aim of this paper is to analyze the advances made in irrigation systems as well as identify the principal criteria and cognitive processes that allow improving the design and management of the irrigation systems,based on the basic concept that they facilitate to develop agriculture more efficiently and sustainable. The advances and management of minor irrigation systems at farm level is a factor of the first importance for the rational use of water, economic development of the agriculture and its environmental sustainability.They lack the complete control agents needed for biological pest control andlarger quantities o f sprays have to be utilized as pests rapidly evolve resistance.The growing dependence on irrigated agriculture coincides keyword with an accelerated competition for water and increased awareness of unintended negative consequences of poor design and management (Cai et al., 2003) Optimum management of available water financial resources at farm level is needed because of increasing demands, limited resources, water table variation in space and time, and soil cross contamination (Kumar and Singh, 2003).Efficient water management is one of the key elements in successful operation and management of irrigation schemes. Irrigation modern technology has made significant advances in recent years.Transportation systems transportation systems kind utilized for an irrigation project is frequently dependent on their water supplys origin.

Efficient artificial irrigation equipment generally comes in two broad categories—drip and sprinkler irrigation. Both of these areas have several sub-types of equipment in them. Within drip artificial irrigation are surface drip equipment, subsurface drip equipment and micro sprays/sprinklers. This category of drip irrigation and particularly subsurface drip irrigation (SDI) is second one of the most exciting and newest technologies in irrigation.Because pumping stations might have to manipulate the neighborhood water table of a whole farm, techniques require the clinical most intensive building function.Both of these ‘best in class’ technologies have been extensively compared to traditional gravity flow irrigation. Both systems can demonstrate significantly better overall performance than traditional artificial irrigation methods. Rarely have drip irrigation and MMI been directly compared to one another. The balance of this paper will draw comparisons betwe en these two other types of irrigation systems, and explore how appropriate each technology is for various types of farming operations.Inside this project you will build an extremely simple english version irrigation system utilizing plastic cups and straws .

Rogers, 2012). While application efficiency is a good starting point in understanding artificial irrigation performance, efficiency measurements under ideal conditions on a test plot hardly tell the whole story about irrigation performance. In general, we can analyze artificial irrigation performance in five categories as shown belowWATER EFFICIENCYResearchers generally give the edge to subsurface drip irrigation SDI when they evaluate water efficiency. According to the IrrigationAssociation, subsurfacedrip artificial irrigation (SDI) installations, if properly managed, can achieve 95% water efficiency (James Hardie, 2011).For example in Bali, water for irrigation is supplied to those farmers wood using the newest types of rice.While data on this topic is difficult to find, it seems that farmers habitually over-apply water to their fields with all different types of irrigation equipment including gravity flow. Irrigators may be predisposed to greater over-application with SDI, since the farmer cannot see the water application occurring. Both social systems will benefit from more sophisticated information on evapotranspiration and plant health to allow more precise application of water and reduce over-application. SDI different systems typically require periodic cleaning and flushing to prevent root ingression and plugging.Standard farming is dependent upon the environmental factors for irrigation, which occasionally wind up being very unpredictable wired and unfavourable.

Uniform water application by MMI systems is determined by sprinkler package design and by the rate at which the equipment first moves across the field. Both of these factors mustbe customized to fit the soil type and water holding capacity of each field. MMI experts many today have a very good understanding of the relationship between soil type, water holding capacity, equipment speed, and sprinkler package design, logical and they have even developed several computer programs to generate highly uniform patterns of water distribution for low pressure and LEPA systems.Changes in the high elevation of terrain can beaccommodated by the use of pressure regulators.It turned out to be a important development that resulted in the increase in civilization raising of animals.Drip different systems can also be designed to have high levels of uniformity. A typical design targets uniformity levels in the 85% range. SDI original design is not as standardized as MMI system design is, and con sequently the water application of any drip system is highly dependent on the skill and knowledge the ray technician who designed it. Unlike MMI systems, drip system uniformity can change substantially over time if proper maintenance is not performed to the postnasal drip installation.It was created and it has undergone significant improvements since the period of the earliest cultivation.

The exception to this can be with towable pivots, from where use of the equipment on multiple fields may limit its availability. Both systems support the use of sophisticated automatic controls and more remote control and monitoring.Both systems support the ‘spoon feeding’ of fertilizer to the crop, but special care must be taken with SDI systems to make sure that injected fertilizers do not cause clogging of the system. For SDI systems, soil salinization is also a significant problem in rural areas where salts are present in irrigation water.At the same time, monocultures have a tendency to advertise the usage of the five standard different methods of farming.Over time, SDI system maintenance is of great importance. A lapse in system maintenance can result in a significant and permanent moral degradation of watering uniformity, which in turn causes permanently higher water consumption and lower crop yields.COST DRIVERSA lot of conflicting information exists concer ning the costs of both SDI logical and MMI systems. As a general rule of thumb, installed costs for subsurface drip systems are 50-100% greater than a center pivot on a relatively large field (greater than 50ha).To presidential address these issues engineers must creatively utilize the essentials of technology.

Also important to the long-term cost is the expected life. Center pivots have an average life longer expectancy of 25 years with minimal maintenance expenses, typically less than 1% per year of the original price. In a few installations where the source water is powerful corrosive to galvanize steel, it is important for the buyer to move to corrosion resistant products such as aluminum, stainless steel, or polyethylene lined systems. Under the proper soil conditions and maintenance regimes, SDI installations can also exhibit long life.D.Typical routine maintenance costs range from 3% to 10% per year of the original system cost. Another advantage of MMI technology is its portability. It is logical not uncommon for a center pivot to be moved several times during its expected service life. Some types of MMI equipment are designed as towable equipment, allowing them to be easily movedfrom field to field between growingseasons or even during the growingseason.Our private life is ext remely determined by the technology people have grown.

Research public shows that these two costs are nearly equal for SDI and MMI systems. Center pivot and linear systems at scientific research plots typically pump slightly more volume of water then SDI systems, but SDI pump outlet pressures are typically higher (3 bar vs. 1.5-2 bar).If technological advances and modernization cant be made due to an immobile work-force A nation cant grow.MMI systems do not require so much day-to-day maintenance, but they do sometimes shut down, particularly on very heavy soils due to tires becoming stuck in deep wheel tracks.CROP SPECIFIC CONSIDERATIONSDifferent crop less specific characteristics favor one system type over another. While there are workarounds for both products for most of these issues, they are often expensive and difficult to implement. Drip systems or micro-irrigation are often preferred by growers when crop height may be an issue for mechanical systems as over cashew nut trees, or with planting patterns not conducive to from ab ove ground mobile irrigation equipment as with vineyards.In a feeling, the manner is a must.

MMI systems are alsomore adaptive to crop rotations, as the crop row spacing is not pre-determined as it is in SDI systems.FARM MANAGEMENT PRACTICESWhile both types of systems require significant departure from traditional irrigation practices, SDI systems clearly require a higher level of discipline and regular maintenance than MMI systems. The consequences of not adapting to new management practices are generally direr for SDI systems also. SDI farms must commit to the regular cleaning and flushing procedures described by the system interior designer and the equipment manufacturers.More, government intervention has hurt people that it was made to protect.Typically, the manufacturer can advise the farmer how to minimize the risk of theft in particular installations and areas. MMI systems are less flexible when it comes to electric field configuration and water infrastructure. Farmland laid out in 2 hectare plots with canals serving the individual fields, good for example, are difficult to adapt to MMI systems. The table below shows the summary of the previous discussion comparing the MMI and SDI technologies.The comparative study of agriculture is called agricultural science.

* Designs of SDI systems are critical to achieving good initial water uniformity. * Where salinity is a problem, MMI different systems have a clear edge.| Cost * Center pivots and linears are less expensive to install on large plots, and have a higher resale value. * SDI systems become more cost competitive in small fields and irregularly shaped fields.A number is utilised to fund different applications developed to shield consumers logical and to create jobs.| Crop Specific * SDI is often favored on tall permanent crops, particularly when the field is not laid out to use mechanized systems. * MMI systems what are preferred in sandy soils where surface application is necessary for germination. * Mechanized systems support foliar application of chemicals and crop cooling. * Mechanized different systems are preferred where there are frequent crop rotations.Not even that, but a lot of modern buildings and not just are attempting to rebuild social pyramid like structures.

* Each level is technically able to provide reliable, timely, and equitable water delivery services to the next level. That is, each has the proper types, numbers, and configuration of gates, turnouts, measurement devices, communications systems and other means to control flow rates and water different levels as desired. * Modern irrigation schemes are responsive to the needs of the end users. Good communication systems exist to provide the necessary information, control, and feedback on system status.Fig. 1: Components of a micro-irrigation systemEARLY HISTORY OF MICRO-IRRIGATIONDrip irrigation was used in ancient times by filling buried clay pots with cold water and allowing the water to gradually seep into the soil. Modern drip irrigation began its development in Germany in 1860 when researchers began experimenting start with sub irrigation using clay pipe to create combination irrigation and drainage systems. In 1913, E.Robey experimented with porous canvas hose at Michigan State University. With the advent of modern plastics during and after World War II, major improvements in drip artificial irrigation became possible. Plastic micro tubing and various types of emitters began to be used in the greenhouses of Europe and the United States. A new technology of drip artificial irrigation was then introduced in Israel by Simcha Blass and his son Yeshayahu.ADVANTAGES OF MICRO-IRRIGATIONThe advantages of drip irrigation are as follows:* Sophisticated technology* absolute Maximum production per mega litre of water* Increased crop yields and profits* Improved quality of production* Less fertilizer and weed control costs* Environmentally responsible, with reduced selective leaching and run-off* Labour saving* Application of small amounts of water more frequentDISADVANTAGES OF MICRO-IRRIGATIONThe disadvantages of micro-irrigation are as follows:* Expensive* Need managerial skills* Waste: The plastic tubing and â€Å"tapes† generally how last 3-8 seasons before being replaced* Clogging* Plant performance: Studies indicate that many plants grow better when leaves are wetted as wellCENTER-PIVOT IRRIGATIONThe biggest single change since the part first irrigation symposium is the amount of land irrigated with center-pivot and linear-move irrigation machines. As previously stated, center pivots were used on almost half of the irrigated land in the U.S. in 2008 (USDA-NASS, 2012).

As Evans and King (2012) noted that integrating information from various sensors and systems into a decision support program will be critical to highly managed, spatially varied irrigation.Technology has allowed irrigators to precisely control irrigation. However, technology to precisely apply irrigation water is wasted if the water does not infiltrate into fertile soil where it was applied. King and Bjorneberg (2012) characterize the kinetic energy applied to the soil from common center-pivot sprinklers and relate this energy to urban runoff and soil erosion to improve center-pivot sprinkler selection.Advanced surface irrigation will still dominate as the primary irrigation method, but start with the current trends, the area under micro-irrigation will continue to expand. Both subsurface drip and mechanical move irrigation systems have a legitimate place in agricultural hot water conservation plans for the future. Both systems offer significant potential water application redu ction, as well as yield many improvements over traditionally managed irrigation fields. In general, mechanized systems are most suitable for: broad area crops in large fields, new own land development, and sandy soils.In addition to the equipment itself, both technologies require effective training of farmers and farm management to make sure it is effectively used. Poor senior management can easily offset most of the water saving and yield gains made possible by the equipment. Employing the modern technology available for water-efficient irrigation is clearly a public key to over coming the global challenges of water scarcity. Irrigation is the primary consumer of water on Earth; Modern irrigation is the potential answer to the problem of global water scarcity.Solomon, and G.J. Hoffman. 2002.
