Homework in Performance Techniques Essay Sound Waves- A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a persons vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them, and so on. The pattern of the disturbance creates outward movement in a wave pattern, like waves of seawater on the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source. Prequency and Wave Length In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the waves shape repeats.[1] It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. [2][3] Wavelength is commonly designated by the Greek letterlambda (ÃŽ »). The concept can also be applied to periodic waves of non-sinusoidal shape.[1][4] The term wavelength is also sometimes applied to modulatedwaves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.[5] The SI unit of wavelength is the meter. Reverberations Reverberation is the persistence of sound in a particular space after the original sound is removed.[1] A reverberation, or reverb, is created when a sound is produced in an enclosed space causing a large number of echoes to build up and then slowly decay as the sound is absorbed by the walls and air.[2] This is most noticeable when the sound source stops but the reflections continue, decreasing in amplitude, until they can no longer be heard. The length of this sound decay, or reverberation time, receives special consideration in the architectural design of large chambers, which need to have specific reverberation times to achieve optimum performance for their intended activity.[3] In comparison to a distinct echo that is 50 to 100 ms after the initial sound, reverberation is many thousands of echoes that arrive in very quick succession (.01 – 1 ms between echoes). As time passes, the volume of the many echoes is reduced until the echoes cannot be heard at all. Refraction Refraction is the change in direction of a wave due to a change in its speed. It is essentially a surface phenomenon . The phenomenon is mainly in governance to the law of conservation of energy. The proper explanation would be that due to change of medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90Â ° or 0Â °. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth. Refraction is described by Snells law, which states that for a given pair of media and a wave with a single frequency, the ratio of the sines of the angle of incidence ÃŽ ¸1 and angle of refraction ÃŽ ¸2 is equivalent to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the opposite ratio of the indices of refraction (n2 / n1): Diffraction- Diffraction refers to various phenomena which occur when a wave encounters an obstacle. Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1665.[2][3] In classical physics, the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Similar effects occur when light waves travel through a medium with a varying refractive index or a sound wave through one with varying acoustic impedance. Diffraction occurs with all waves, includingsound waves, water waves, and electromagnetic waves such as visible light, x-rays and radio waves. As physical objects have wave-like properties (at the atomic level), diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. Passive Absorption- According to this theory ions are absorbed by the root along with mass flow of water under the influence of transpiration. This theory failed to explain the salt accumulation against osmotic gradient. An increase in transpiration pull increases the uptake of ions by the roots. The uptake of ions by free diffusion. Thus, mass flow of ions through the root tissues occurs due to transpiration pull in the absence of metabolic energy.

Mississipi Burning Essay Example for Free

Mississipi Burning Essay The film, Mississippi Burning (1989) can be classified as a very useful source for a historian studying the Civil Rights Movement, however, there are a few noticeable limitations that could prevent the historian from gaining a full understanding of the true culture in the Southern States of America. The film thoroughly examines the role of the Klu Klux Klan and touches upon the role of the media. Despite the useful information that is provided throughout the film, there are certain flaws that limit the historian from gaining knowledge on the true nature of Southern Americans. In the 1950s the emergence of the Civil Rights Movement triggered the Klu Klux Klan organisations to ramp up their terrorisation of the African Americans. The most significant of these was the White Knights of the Ku Klux Klan led by Robert Shelton. In the Deep South considerable amounts of pressure were put on blacks by the Klan not to vote. An example of this was in the state of Mississippi. By 1960, 42% of the population was black but only 2% were registered to vote. Lynching was still employed as a method of terrorising the local black population. (Klu Klux Klan, http://www. spartacus. schoolnet. co. uk/USAkkk. htm) The film ‘Mississippi Burning’ supports this information and displays some of the methods the Klu Klux Klan used to attack and threaten African Americans as well as those who supported integration between blacks and whites. The media played a significant role in the Civil Rights Movement. People throughout the world were able to view significant events such as riots, marches and certain court cases. This meant that people became more aware of the extent of violence and injustice that was bestowed on African Americans, particularly in the small country towns in the Southern States. Actually viewing all this violence sparked even more rage amongst those who believed in the Civil Rights Movement. While the majority of White Americans still harbored racist views, many were horrified with the beatings, murders and other brutalities exposed by the media. Many northern whites did not understand what was happening in the South. The new surfacing of television delivered powerful images to the nations living room. Print media was important, but it was television coverage that played a major role in the changing of attitude towards the Civil Rights Movement. The film ‘Mississippi Burning’ subtly but effectively touches upon the role of the media. Throughout the film, there are shots of cameramen filming significant events such as the search for the missing activists and the court case for their murder. This allowed viewers to get a sense of how much the media was used to in this era to help people around the world become aware of atrocities occurring in Southern America. Despite the valuable information, that supported other sources, in the film Mississippi Burning, there were various inaccuracies that could potentially mislead a historian studying the Civil Rights Movement. To make the film more entertaining, it was clear that the producers of the movie were fairly biased towards the Southern Americans and portrayed them all as ‘redneck’ racists. In actual fact there were a number of residents in Mississippi who did accept the Civil Rights Movement and participated in marches and riots against those who refused to do so. Another inaccuracy in the film was the way the detectives discovered Deputy Pell was guilty of participating in the murders of the Civil Rights Activists. In the film, Agent Anderson becomes relatively close with Mrs. Pell, Deputy Pell’s wife. He eventually manages to milk information out of her. In reality, Klu Klux Klan member, James Jordon, confessed to the FBI agents that he witnessed the murders and agreed to co-operate with the investigation. Mississippi Burning is in many ways a useful secondary source for a historian studying the Civil Rights movement. The Klu Klux Klan were heavily acknowledged in the film and their methods of terrorising African Americans were exceptionally realistic, supporting other sources about Southern American culture. The media was also touched upon throughout the film, providing evidence that the media played a large role in the acceptance of the Civil Rights Movement. Despite the small inaccuracies in the film to create a more entertaining storyline for viewers, the benefits of the information provided, outweigh the flaws.

The Century Closed The World Became Smaller Information Technology Essay

The Century Closed The World Became Smaller Information Technology Essay As the century closed, the world became smaller. The public rapidly gained access to new and dramatically faster communication technologies. Entrepreneurs, able to draw on unprecedented scale economies, built vast empires. Great fortunes were made. The government demanded that these powerful new monopolists be held accountable under antitrust law. Every day brought forth new technological advances to which the old business models seemed no longer to apply. Yet, somehow, the basic laws of economics asserted themselves. Those who mastered these laws survived in the new environment. Those who did not, failed. Purpose The purpose of this Master Thesis is to analyze the transportation and logistics industry and examine how eBusiness has affected this industry. We will study the changes that have already occurred as well as entry to identify possible future eBusiness trends as well as changes within the industry. Delimitation The expression electronic commerce usually refers to exchange that utilizes an electronic channel for communication between buyer and seller. This electronic channel could be for instance EDI or the Internet. The focus of this thesis is, however, only exchange that uses the Internet. We therefore use the expression eBusiness. We define eBusiness as exchange that is enabled or facilitated by the use of the Internet in the buyer-supplier relation. Method In this section the methods of work that have been used in our analysis will be explained. Triangulation has been used as a mean for combining the different quantitative and qualitative methods used in order to illustrate the problem from several different angles. The purpose of this was to improve the analysis results validation. Tackling the problem from several directions has also improved our knowledge of the same. The three methods we have chosen are review of literature, questionnaire sent to companies in the industry and case studies. The main reason for choosing these methods was to get a broad understanding of the industry situation and include as many relevant factors as possible into our analysis. This way we reduce the risk of missing important aspects because of limitations in our frames of reference and our analytical tools. Theoretical framework One of the most discussed issues today is the new digital economy. We are living in and doing business in a world where information and ideas are the new capital. The key driver of this economic shift is the Internet, hence the term digital economy. The Internet has wielded this power because it has introduced two essential changes that together are turning industries inside out. These two changes are: 1. The Internet makes unprecedented amounts of information available more easily, universally and cheaply than ever before. 2. The Internet creates a universal and instant connection. A connection between people, between business and their customers and between business and their partners. These two central changes have in turn generated a host of new change factors that businesses must come to terms with. Figure1 shows how new communication technology affects different areas within a company that in turn leads to changed industry structure. This also illustrates the structure of the theoretical also illustrates the structure of the theoretical approach. One can summaries the literature written on eBusiness into three major areas that are highly important in business making. Areas that all have been affected by the use of the Internet: industrial relations, business efficiency and products. There are also other significant changes that the Internet have given rise to and/or driven further ahead, which are described in Other the Internet Driven Effects. EBUSINESS AFFECTS RELATIONS To understand and intelligently attack industrial marketing problems, a number of substantial differences between industrial and consumer marketing must be recognized. These differences are often of degree rather than kind, but the degrees of differences are substantial. Marketing in the industrial world is much more a general management responsibility than it is in the consumer-products field. In a consumer goods company major changes in marketing strategy can be made and carried out within the marketing department. EBUSINESS AND PRODUCTS Every business today competes in two worlds: a physical world of resources and a virtual world made of information1. The latter has given rise to the world of eBusiness, a new locus of value creation. The value chain in the physical world treats information as a supporting element of the value-added process, not as a source of value itself. By gathering, organizing and distributing the information received from the market space, companies can use it to create new products and new value for customers in the virtual value chain. In this work Product is used as a metaphor for products or services. The nature of products can therefore be both tangible and intangible. Often a companys subject of exchange is part product and part service. One of the most noticeable consequences of the economic shift of paradigm today is that the part of a product that is service or information becomes larger and larger. In many industries not widely considered information businesses, information actually r epresents a large percentage of the cost structure1. Investments in the electronic channel displace traditional sales, marketing and service costs; moreover, the technology allows companies to offer increasingly higher levels of service without incurring incremental costs for each transaction2. Also today, knowledge and information are the prime commodities, either as the main object of transactions or as very important component of them The Internet and differentiation The competitive situation on the Internet is often described as perfect competition. What are the consequences of this? According to economic theories, firms competing on a market characterized as perfect competition will, in the long-run equilibrium, make zero economic profit4. Very few companies want to compete on a market without economic profit. Companies should therefore avoid competing solely on the basis of price. Consequently, the issue of differentiation will be more important in eBusiness. A well-known way to differentiate products is by adding services to the original offering. A companys offering can therefore, if associated with the right services, be more valuable to a customer than a competitors equivalent product. The Internet could for example be used to provide value-adding information or services to buyers of a tangible product, thus differentiating it from competitors. The Internet and diversification The Internet can be seen as a platform for innovation. It is a way to produce new combinations of information and products/services without incurring the traditional costs of complexity that exists in the physical world. For instance, information that arises from a companys traditional business can be gathered and used to serve new customer segments. Standard Poors Corporation, a company that traditionally provided financial information to institutional customers, uses its stored information to provide financial planning services to private customers over the Net. INCREASED BUSINESS EFFICIENCY One of the major reasons for the immense interest for eBusiness today is that it has great influence on business efficiency. The primary reason for this is the fact that eBusiness can decrease transaction costs, i.e. the costs related to administrating each purchase. Together with the way the Internet lets companies integrate and organize their flow of information we get a winning concept for lowering costs and increasing efficiency. Consequently, the Internet can increase efficiency in complete supply chains, thus increasing the capacity in whole networks. The Internet also increases the transparency of markets and thereby enables buyers to compare products and prices quickly and easily. This puts them in a better bargaining position and shifts the information advantage from sellers to buyers. Hence, the Internet might induce lowered costs for companies purchasing online and therefore indirectly affect the efficiency. Transaction costs One of the most significant effects of eBusiness is that transaction costs decrease. Transaction costs are most important in business to business cases as consumers not are directly afflicted with costs for spending more time while shopping. However, as the lowered costs move down the value chain, in the end the consumer will benefit as well. IMPLICATIONS OF EBUSINESS What are the implications of eBusiness on B2B relations? We have presented a review of how affects B2B relations. We would now like to summaries this and at the same time point out the main issues of eBusiness. These will later on be used as a base for our analysis of the transportation and logistics industry Relationships We believe the Internet as a relationship enabler is of such importance that it needs to be dealt with specifically. The Internet can affect a companys relations with customers, suppliers, partners and community. eBusiness and products The Internet allows firms to create both new and enhanced products and services. Creating new services is made possible by the Internets capacity for transferring large amounts of data cost-effectively. Also, the Internets geographical reach and propensity to connect people and companies give rise to new products and services. Consequently, eBusiness can be new business. Moreover, eBusiness can affect profits. Increased Business Efficiency One of the major reasons for the immense interest for eBusiness today is that it has great influence on business efficiency. There are primarily two reasons for this. First, the Internet lets companies integrate and organize their flow of information. Second, eBusiness can decrease transaction costs, i.e. the costs related to administrating each purchase. Consequently, the Internet can increase efficiency in complete supply chains or networks. INDUSTRYDESCRIPTION Mankind has always depended upon the means of transportation and the development of transport systems is directly associated with the expansion of civilization. Moreover, there has always been connection between production, trading and transportation. Even the old Egyptian Pharaohs realized the value in having a well functioning net of transports and their usage of the Nile can now be recognized as the foundation of their empire1. The first city in Sweden also developed by waterways since traffic on water was a condition for the existence and growth of cities in these days2. Since a geographical area, city or nation alone cannot produce all the goods demanded, a need for transports to import the missing goods arises. The specific area can also export their surplus to other regions that lack these goods and a two-way flow has thereby occurred. After a while, regions will start to specialize, i.e. they will produce the goods that will give them the most comparative advantage3. Speciali zation makes efficiencies through economies of scale and economies of experience possible, which in turn can lower costs. This makes it possible for companies to ship their products even further away. The larger production volumes also demand larger markets, which is why companies look abroad to sell their products. THE EVOLUTION OF TRANSPORTATION Up until the beginning of the nineteenth century, shipping was the most important mean of transportation. Then the industrialism started to sweep the continent and by the division of labor and automation, companies could now mass-produce goods using economies of scale, which demanded larger markets as mentioned earlier. This required a well working transportation net, which made the railroad the most effective means of transportation4. The railroad was needed in order to deliver raw material to factories and to distribute produced goods to the markets. LOGISTIC QUALITY Over the years vendors have noticed that buyers tolerance for errors is getting smaller and logistics managers everywhere are being put under pressure because of this. Quality is important to supply-chain thinking because, literally, the supply chain is no better than its weakest link. Whichever link in the supply chain is responsible for questionable quality will be the first eliminated1.Quality has always been important to logistic operators, and today nearly all companies appear to be in the pursuit of high quality. There are several reasons for this2. One is the just-in-time (JIT) concept, which leaves no spare stores to fall back on in case a defect is found. A second is the replacement of mechanical devices by electronic ones with the latter being much more accurate. A third reason is that as possibilities for partnership arrangements present themselves. Companies are wary of being linked to a supplier that does not share similar ideas or believes about quality measures or conc epts. THE NEED FOR INFORMATION IN THE INDUSTRY The main purposes of goods transports are to deliver material or products from one location to another at a required moment. The transportation process therefore generates a flow of goods. To accomplish the transportation mission satisfactorily there is a great need for information. Case study: Schenker-BTL BTL is an acronym for Bilspedition Transport and Logistics. The Compan was one of the dominating transportation companies in Sweden for a long time. Now BTL has been merged with Schenker AG and formed Schenker-BTL. BTL is thereby part of one of the largest transportation companies in Europe. THE COMPANY We will in this section give a brief description of Schenker-BTL (from now on referred to as S-BTL). It is however, difficult to find accurate and updated information about the new company. Even the employees seem to be confused about the structure of their company. Due to the transformation the company is going through much of the information found in annual reports is inaccurate. Also, as a consequence of the new ownership, there will be no new annual reports or interim reports released from S-BTL. Our description is at large based on information obtained through interviews and information form the corporate website. The purpose is to give the reader a rough description of the companys size and business. EBUSINESS There are two major approaches to eBusiness for S-BTL. The Internet strategy is primarily focused on providing logistic support for companies that want to do eBusiness. Moreover, S-BTLs offers services related to its pure transportation business on the corporate website. We have analyzed how S-BTL uses the Internet to create new business and add value to the traditional services. We will first describe how S-BTL uses its website, then we discuss S-BTL as a logistical partner in eBusiness. SUMMARY United Parcel Service (UPS) is one of the worlds largest express carrier and package delivery companies. The company was founded in 1907 in the USA and today operates an international small package and document network in more than 200 countries and territories. Every day UPS delivers more than 12 million packages and documents. Since the company serves a global market with its transportation services and in order to reach its customers quickly, UPS has turned to information technology and electronic commerce to help them gain a leadership position. THE SURVEY As a part of our work with analyzing how the Internet affects the transportation industry we have sent out a survey to 82 of the companies in this industry. We chose the companies that are members of the Swedish International Freight Association and that have a web site. The purpose of the survey is to investigate how Swedish transportation companies use the Internet and what sort of problems it brings. We do not intend to make any quantitative conclusions for the industry as such since the sample of companies is to narrow. The survey will simply act as a guideline to the future the Internet usage in the transportation industry THE QUESTIONS The questions were divided into five areas: historical and future changes, strategy, prime movers, purpose, problems and miscellaneous. In the first two we intended to find out what the companies in the industry thought of the Internet, how it had affected their business making and what might happen in the future. The following four questions were asked to indicate the purpose of an Internet investment, which was behind it and what problems it brought along. The last question was about other significant trends in the industry that are not entirely connected to the Net but still important for the industrys future. CONCLUSIONS Until now, the Internet has primarily been perceived as a communication tool, both for internal as well as external use. This is also regarded to be of future importance though the companies also see the Net as a way to attract new customers. Another field of application for the Internet is marketing as well as a tool for development of new products and/or increasing their values. Only half of the companies in the survey seem to have a specific the Internet strategy whereas the other half has not. However, at a majority of the companies, the Internet related issues are often discussed on top management level leading us to believe that the industry has realized the Nets importance. An explanation to why the Internet has not had a serious breakthrough yet might be the Y2K problem. A total of 78 percent held this as a more important issue. Nevertheless, most companies consider the Internet to be a natural part of future strategies and significant for future competitive advantage. For mo st companies, the prime movers for an Internet investment have been either top management or a specific person at their company. The purposes of the investment were to attract new customers, improve customer service, and increase the value on services, sales and to satisfy to customers expectations. However, not as many as we expected claimed the purpose of the investment to be efficiency improvements. The majority of the companies did not appear to have any specific problems with their Internet investment. Not even the complexity, security and reliability issues seem to be major obstacles. Neither do the companies believe that the Internet usage will reduce the personal contacts. Still, many feel that it is difficult to measure the effects of their investment. The future trends appear to be at home deliveries and logistics management. However, fewer than we anticipated thinks that single sourcing and Net-based transportation exchange firms would have a significant impact on the transportation industry. Analysis One of the most noticeable consequences of eBusiness is that new Business models emerge. The emerging eBusiness models are a result of the new technological possibilities for communication and the new possibilities for creating products and services that the Internet brings about. This has been noted in several industries and the transportation and logistics industry is no different. We have found that companies in this industry go about eBusiness in three ways. We will discuss each of these as a model of eBusiness. The models are. 1. The first model includes companies that use the Internet for customer interaction. Usually this means that regular off-line services are marketed on a corporate website. We call this model Classic Services. 2. Logistic Providers for eBusiness firms. Companies develop and operate logistic solutions for firms that sell goods on the web. Generally involves delivering to consumers, i.e. at home deliveries. 3. New business models that are completely the Internet-based. Companies in this group has no physical assets, the concept is to connect buyers and sellers of transportation services.à ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬Ãƒ ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬Ãƒ ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬ Classic Services The first business model to be discussed in the analysis is the classic services model. As the name implies, this eBusiness model is about marketing classic transportation services on the Internet. They are classic in the sense that most of the Internet services are originally offered off-line. This analysis will describe the services and examples on how the companies in our case studies use them will be given. We will also discuss how the Internet is used for communicating and some of the problems related to the classic services. The Internet services The services offered by the companies in this group are usually regular off-line services that have been converted to the Internet. Common services are booking, tracking and timetables, thus, services that traditionally have been handled via telephone or fax. The customer is often required to register to use the services. We will now give a few examples of regular services. Communication The companies in the classic groups use their websites for communicating with both customers and community. Usually the company and its services are presented along with press and investor information. Moreover, most companies give information on how to reach them and some also answers to frequently asked questions have. Using the Internet for communicating company information is a fast and effective channel and should therefore not be neglected CONCLUSIONS This chapter will present our conclusions on how the transportation and logistics industry has been affected by eBusiness. We will also present our view of how eBusiness will evolve in this industry. The results exhibited in this chapter are based on the case studies and the survey, which have been presented throughout this thesis The most significant effect of eBusiness is that new business models emerge. These models are a result of the new technological possibilities for communication and the new possibilities for creating products and services that the Internet brings about. We have found three different eBusiness models in the transportation and logistics industry. We refer to these as Classic Services and Logistic Providers. The Classic Services eBusiness model is about marketing classic transportation services on the Internet. The Classic Services group of companies is the dominating one in our case studies. Common services are booking, tracking and timetables, thus, services that traditionally have been handled via telephone or fax. The usage of the services is generally very low. The services found in this group are seldom very innovative. Still, we regard the booking and tracking services to have a great potential both for increased efficiency as well as enhanced customer service, but the concepts has to be reworked in order to attract more customers. The customers booking process has to be assessed in order to establish how the Internet is best utilized to simplify the customers situation. Also, companies need to attend the problem of how reach the efficiency increases that the Internet enables without losing the social contact and trust that the customers demand. Being a Logistic Provider implies t hat the transportation and logistics company provides services such as: warehousing, inventory control, assembling and distribution to their clients. The transportation companies believe that strategic partnering with the Internet retailers has the greatest potential in eBusiness, this because the Internet shopping is believed to grow immensely over the next few years. Now the Internet start-ups are also considered to be more inclined to outsource the logistic operations than most traditional businesses. The biggest change that the Internet business has brought about for the industry is the increase of at home deliveries. The important issues in this new business are time of delivery (evenings), payment, capacity, utilization and logistic efficiency. The future All of the companies that we have studied are industry pioneers in the Field of eBusiness. We believe that other companies in the industry will go about eBusiness in the same way as the companies that we have described. The future will show which models that are profitable. We believe that the Classic Services model will gain in popularity as more transportation companies and customers realize the potential for efficiency increases this model has. Yet, there do not seem to be any plans to extend the range of offered services. Some companies believe that technological developments will enable further increases in efficiency and enhanced service. We also expect that an increasing number of small and medium sized firms will discover how the Internet can be used for connecting complete value chains. The Internet can thereby transform the way that third party logistics is performed. The future of the Logistic Providers is set by the rate at which the Internet trade grows. Though, this growth is to some extent due to how well the at home delivery services are developed. The marketplace Models will probable need a few years to show results. The success of this model is depending on a cumbersome change in both attitude and behavior of transport firms and customers.

Censorship in Schools Essay example -- Censorship Censoring Literature

Censorship in Schools There has recently been a renewed interest and passion in the issue of censorship. In the realm of the censorship of books in schools alone, several hundred cases have surfaced each year for nearly the past decade. Controversies over which books to include in the high school English curriculum present a clash of values between teachers, school systems, and parents over what is appropriate for and meaningful to students. It is important to strike a balance between English that is meaningful to students by relating to their lives and representing diversity and satisfying worries about the appropriateness of what is read. This burden often falls on teachers. The purpose of this research paper is to discuss censorship in schools and to argue that the censorship of books in the high school English curriculum is limiting and takes away literature that is meaningful to students. How a Book is Censored Brinkley describes a few actions that can lead to the censoring of a book in a school or school system: An expression of concern is simply a question about the material with overtones of disapproval; an oral complaint is an oral challenge to the contents of a work; a written complaint is a formal written challenge to the school about the contents of a work; and a public attack is a public statement challenging the contents of a work that is made outside of the school, usually to the media to gain support for further action (1999). Brinkley also points out an important difference between selection and censorship: Selection is the act of carefully choosing works for an English course that will be age-appropriate, meaningful, and fulfill objectives, while censorship is the act of excluding works that some con... ...nts out that censors often pick out very short passages of a work without taking into account its context in the entire scheme of the novel.

Analytical Essay :: Analytical Essays

The construction last year of a shopping mall in downtown Oak City was a mistake. Since the mall has opened, a number of local businesses have closed, and the downtown area suffers from an acute parking shortage. Arrests for crime and vagrancy have increased in nearby Oak City Park. Elm City should pay attention to the example of the Oak City Mall and deny the application to build a shopping mall in Elm City. Analyzing this argument brings up a lot of questions to whether this is a relevant argument or not. A lot of assumptions are made without enough facts to support them. It can be said that the mall could have directly or indirectly been a part of the problems. The problems are: Increase in crime and vagrancy, businesses closing, and a parking shortage. It is not logical to say that it is sole cause of the situation. This argument states that the building of the mall is the reason that some businesses have went out of business. To say that the mall and the closes of the businesses go hand in hand is not totally accurate. There are a number of reasons that could have led to the closing of the businesses. For one example, you could say that a change in the economy might have led to the closures. If this occurred after the holidays, it could say that people spent most of their money during this time and it could have hurt some businesses beyond the point of repair. Also, this argument doesn?t state what kinds of businesses had troubles. If it was something as in a grocery store, the mall could not be the cause because the mall doesn?t interfere directly with the food industry. Also, a majority of small businesses succumb to larger ones. This area is not exempt to the possibilities that this is what could have happened. This argument does not state if mergers of smaller companies related to the statement. The argument tries to tie together that a parking shortage was caused by the Oak City Mall. While in turn the mall would bring increased foot traffic, it would also bring along more commerce to the city, thus businesses should not have struggled as previously mentioned. A number of factors could have added to the parking shortage. With most communities now, population increases every year.

The Treatment of Women in Bram Stokers Dracula Essay -- Dracula E

The Treatment of Women in Bram Stoker's Dracula  Ã‚   In reading Bram Stoker's Dracula, I find the treatment of the two main female characters-- Lucy Westenra and Mina Harker-- especially intriguing. These two women are two opposite archetypes created by a society of threatened men trying to protect themselves. Lucy is the Medusa archetype. She is physically attractive, and wins the heart of any man who comes near her (e.g. Arthur, Quincey, Jack, and Van Helsing). Her chief quality is sensual beauty, but her sexual desire is repressed and not allowed to communicate. And yet both the spiritual side and the sexual side are in her, and when the long repressed sexuality finds a vent, it explodes and takes over completely. In other words, she is transformed into the completely voluptuous female vampire precisely because her sexual side of personality had been completely buried by her Victorian education. Her repressed self needs such expression that when Dracula came along, she went out to greet him, and then invited him into the house (by opening her window to the bat). He is her vent for sexual expression. When Lucy becomes a vampire herself, John Seward describes her as follows: She seemed like a nightmare of Lucy as she lay there; the pointed teeth, the bloodstained, voluptuous mouth -- which made one shudder to see -- the whole carnal and unspiritual appearance, seeming like a devilish mockery of Lucy's sweet purity (252; ch.16). And for this voluptuous Lucy he has no pity: "the remnant of my love passed into hate and loathing; had she then to be killed, I could have done it with savage delight" (249; ch.16). But why this attitude? I believe it is the aggressive sexuality that the vampire Lucy displays that ... ...in excluding her from their undertakings, and include her again. However, now that she is infected with vampire blood and is capable of reading Dracula's mind, the men both fear and need her. They are forced to accept her in the public realm, but the quest is to eventually rid her of evil influence and restore her purity again, that is, to turn her back into the virtuous woman who will stay in the dominion of the home and not pose a threat to men. The end of this novel is the restoration of a world as the Victorians know it: the vampire destroyed, the women rid of their evil sexual desires and kept out of the dangerous world outside their homes, and the men safe and free in a male-dominated world, playing their exclusive gallant, intelligent, and adventurous roles.    Text Cited Stoker, Bram.

Agricultural Science Essay

The poultry house was properly sanitized in order to keep the chicks healthy and warm in all weather conditions. This was also done to keep away diseases from the chicks. The poultry house was erected at an east – west orientation. * Tools were collected (e.g. broom, empty bags, disinfectant, shovel) * Old litter was shoveled up, bagged and removed to the compost heap. See figure 1. * Using the broom, the mesh and ceiling were cob-webbed. See figure 2. * Materials that were caked onto the floor was scraped using the shovel, the floor was then washed with disinfectant. The tarpaulin was hoisten for sunlight to penetrate the area. * The area was left to dry for two (2) days. * The tools were cleaned and dried then returned to the storeroom. Preparation of the Brooding Area (21|9|11) Brooding is the special care given to the chicks. Brooding is important as it keeps the chicks warm and safe when they are small. * A confined area was constructed for baby chicks. * Tools and materials were collected e.g. sawdust, newspaper, light bulb, waterers, feeders * Sawdust was placed on the floor and covered with newspaper to prevent the baby chicks from swallowing the sawdust. See figure 3. * The tarpaulin was rolled down to prevent cold air and water from entering the area. * An infra red bulb was placed in the brooding area to give warmth to the chicks. * Feeders and waterers were washed and disinfected. Water was placed in the waterers. They were then placed in the brooding area. See figure 4. * The foot bath was washed and disinfectant (Jeyes) was then placed in the foot bath to remove bacteria from the feet. See figure 5. Arrival of chicks (26|9|11) Upon the arrival of chicks, they were checked for abnormalities and were introduced to water before they were given feed. Daily Observations Daily observations are carried out from the arrival date to slaughtering date. During this period a number of activities were carried out. * Feeding: young birds are feed daily to enhance growth and health. * Washing of feeders and waterier. * Removal of old newspaper and replacing them with new ones. * Turning over the litter, with shovel and removing wet litter. * Removal of dead birds and tallying. * Adjust tarpaulin. * Adjust automatic feeder and waterer. Expansion Of Brooders(13|10|11) The chicks were removed from the brooding area to a larger section of the poultry house where they will stay until they are ready for slaughtering. Mortality Rate 75 chicks were bought and a total of 3 died. The mortality rate was worked out to be 4% (375*100) . Preparation for slaughtering A day before slaughtering feeding was withdrawn from the chickens so as to reduce wastage and also to prevent the presence of food in the crop when it is removed. However they were still allowed access to water. Slaughtering (16|11|11) The head of the birds were positioned downwards so that the blood could flow down easily. The heads were cut off using a sharp knife. The chickens were scalded and plucked. Scalding was done by immersing the chicks in a bucket with warm water for about 45-60 seconds. Scalding the chicks allowed the feathers to be removed easily; plucking was done immediately after the scalding process. The chickens were then eviscerated (process of removing everything inside the body and also the head and feet). This process involves * removing by making a cut behind the neck. * separating the esophagus, trachea and crop from the neck skin. * opening the body cavity by making a cut near the vent, extending the cut around the vent. * removing the viscera (including the lungs) through the opening. * washing the chickens thoroughly when all the contents of the cavity were removed * separating the heart, liver and gizzard; the heart was trimmed to remove any thing that may be attached to it. * trimming the gall bladder, carefully, away from the liver. * splitting the gizzard lengthwise and washing the contents away; the lining was peeled away to make it edible. During the eviscerating process the chickens were put on a sanitized table. After evisceration the carcass was cooled by using ice water. They were then bagged and marketed. Dressing & Marketing of Birds (16|11|11) Birds were defeathered and the contents were removed, the offals and the carcasses were placed in clean water and put to chill in ice water. After thirty minutes they were then drained and packaged. They were then placed in a refrigerator for storage. Cleaning up the area (16|11|11) The feathers were remove to a corner of the farm to be dried and burnt, the intestine was boiled, some was given to the dogs while the rest was disposed of, the slaughtering area was sanitized with disinfectant and washed and left to be dried for further use and also to keep away flies and other insects. Projected Income Output * Income Output = 375 lbs Price = $130.00 Projected income = 375 lbs * $130.00 $48,750 Projected Expenditure Spade $1,200.00 Booster $420.00 Broom $150.00 Hose $1,000.00 Waterer (2 * $950) $1,900.00 Feeder (2 * $950) $1,900.00 Dust Mask (1 pack) $600.00 Baby Chicks (75 * $63) $4,725.00 Plasson (2 * $3500) $7,000.00 Sawdust (5 * $200) $1,000.00 Tarpaulin (2 * $250) $500.00 Feed (12 * $1300) $15,600.00 Disinfectant Jeyes $900.00 Labour $3,000.00 Total $39,475.00 Surplus : Projected income – projected expenditure Surplus = $48,750.00 – $39,475 = $9,275.00 Actual Income and Expenditure Actual Income Output * Price Output = 225 lbs Price = $130.00 Actual Income = $29, 250.00 Actual Expenditure Booster (1 * $420) = $420.00 Dust Mask (1 * 450) = $450.00 Feed (12 * 1,300) =15,600.00 Baby Chicks (75 * $63) = $725.00 Labour =$3,000.00 Total = $24,195 Surplus: Actual Income – Actual Expenditure = $29,250.00 – $24,195.00 = $5,055.00 COST ANALYSIS Seventy five (75) chicks were bought, 72 were slaughtered due to a 4% mortality rate. It was estimated that all the seventy five (75) chicks bought would be slaughtered. The average weight per chick was 5lbs; the actual weight was 3.125lbs. This resulted in a change in the income, causing a decrease in profit. The actual income was $5,055.00 for chicken meat while the projected income was $9,275.00. The projected expenditure surpassed the actual by $15,280. This was due to fact that we did not purchase the spade, broom, hose, waterers, feeders, plasson, sawdust, tarpaulin and the disinfectant (Jeyes) as they were provided by the school. The projected income and expenditure was more than the actual, however, we still made a profit and not a loss. General comments Broiler production has become a popular farming activity in the West Indies (W.I.). In Jamaica poultry provide a source of income in a short period of time more than other farm works. To enter the world of poultry you do not need a larger start-up capital so you will find more and more people involve in the poultry business. Another factor is that in less than two month there is a turnover on the capital with proper management and a larger area of production. Since the required space per bird is 6 square inch (15 cm2). It was a success due to the fact that we made a profit and not a loss, however, we could make more profit if we(students) had paid more attention to the chicks. Recommendations * Increase the size of the poultry house and brooding area, in order to increase poultry production. * More attention could be paid to the chicks by students. * Provide a farm man to work on weekends and holidays. Conclusion After carrying the actual project it is concluded that the rearing of broiler bird takes a minimum of 6 weeks. With proper management boiler production also provide a good profit, it is also observed that boiler has a high dressing percentage and a good converter of feed using an average of two to three pounds of feed to provide one pound of meat.
