The temperature of the acid Essay Example for Free

The temperature of the acid Essay My conclusion fully supports my previous hypothesis and predictions that as the temperature increases, the calculated rate of reaction increases. This is shown in my final table of results and graph. However, it does not support my predicted results exactly, as the pattern of the graph is not as I had expected. This can be explained if necessary by inaccuracy of equipment, error in timing or simply human reaction times and judgement and therefore is less important than the accuracy of the predicted fact that the temperature and the rate of reaction are proportional. From my earlier notes I can see that this is because as the temperature increases there is more heat energy. This can be converted into kinetic energy, which makes the particles move around faster, and therefore have more chance of colliding with each other. Also, larger volumes of heat and energy means more effective collisions are created. I therefore conclude that the relationship between temperature and rate of reaction is indirectly proportional, in that as the temperature increases, the rate of the reactions taking place increases also. Evaluation I feel that both my method and equipment were fairly reliable, as my results fit fairly closely with how I imagined they would. I have taken enough results and repeats, and these are close enough to my prediction to create and support a firm conclusion. However, a few of my results were slightly anomalous, and the graph did not end up in the exact shape I had predicted, and therefore there must be ways to make my experiment more accurate. There are several things I have noticed which could have adversely affected any results I got, and I have tried to think of ways in which I could alter them if I was to re-do the experiments now. It is important to remember that the line of best fit on my graph is a straight line, showing only a basic upward trend, not a graph which accelerates as I predicted. When, towards the end of the given time for practicals, I was looking to re-do any points, I only looked at my first graph of time taken against temperature (see page 10), not at the graph of rate against temperature. Therefore, instead of trying to repeat points which fall a little away from my best-fit line, such as that at 24i C or that at 50i C, I added another point at an important stage in my original graph, at 18i C. This seemed a valuable point, but looking at my rate graph it lies exactly on my best-fit line. So while it does serve to highlight the accuracy of my results and best-fit line, it would probably have been more valuable to repeat the points at 24 and 50i C. Because of reasons stated (on page 8), the point at 50i C didnt have a repeat to begin with, and therefore ought to be looked at as less valid than the other points anyway. Most of the potential inaccuracies in my experiment were caused by my equipment, rather than the method, as I felt that my method was reliable. I especially liked my system for heating, as it almost invariably kept the acid and tablets at a constant temperature and it produced accurate results. There are a few reasons that I can identify why the rate may have been above my best-fit line (such as at 24i C). If this is the case, it means that the product of 50cmi carbon dioxide was produced within a shorter time than expected. This could be due to the temperature being higher than I had believed (for example if it rose during the reaction), or the gas syringe not being back to exactly zero before starting the experiment (sometimes I found it got knocked so it was already at approximately one or two cmi ). Therefore, in theory, checking and making sure of both these things before the start of each experiment could have improved my method, and if I was to repeat the experiment I would ensure I was doing these things. There are also reasons why the rate may have been below my best-fit line (such as at 50iC). This means that the product (50cmi of carbon dioxide) took a longer time to be produced than expected, or that it took a longer time than average to show in the gas syringe. This could be due to the temperature being lower than I thought (for example having dropped during the reaction). In future, this should be checked before the experiment is started. It could also be due to faulty equipment, like the gas syringe getting stuck or the rubber joining the tube not being on properly, or being on different amounts so that the gas took longer to travel up the tube. If the experiment was repeated, the gas syringe should be chosen carefully as one which is not either too loose or too stiff, and the joining tube should be put on properly, so that no gas is allowed to escape when the pressure builds up inside the conical flask. Also, a certain degree of error must be allowed for in that a second person is necessary when starting an experiment. This is because you need one hand to add the tablets, one hand to put the bung in and a third hand to start the stopclock. This increases the chances of the experiment being inaccurate, as two different people are very unlikely to be completely synchronised. Therefore the gas has time to escape unnoticed at the start of each reaction before the bung is put in. I can see little which could be done about this in future experiments. In both cases (above or below the best-fit line) the experiment would have benefited from a greater number of results being taken at smaller intervals. This would probably have further supported my conclusion and may also have more accurately displayed a less obvious trend such as the one I originally predicted. Taking results in a wider range, (for example from 5i C to 70iC) with repeats to verify accuracy, would have strengthened my evidence. It would only have done this if, as I imagine, a continuing trend showed in the extra results. In all of the experiments, a degree of error in continuity must be taken into account. It is extremely unlikely that the tablets all had the same mass, or that there was the same volume of hydrochloric acid down to the last drop. I tried to make this as accurate as possible, using a burette instead of a measuring cylinder, and only getting the tablets out at the last minute so that they were as whole and un-tampered-with as they could be. If the experiment was to be repeated on a larger timescale, I could measure the mass of the tablets to increase accuracy. It is also impossible to swirl the beaker at exactly the same vigorousness every time, although I tried to keep it as constant as I could. If I was looking to test these results on a much wider scale, I could use other common antacid tablets with similar active ingredients, keeping the type and volume of acid constant. This would prove that the tablets that I used were regular, and didnt just coincidentally produce typical results.

Types And Characteristics Of WANs Information Technology Essay

Types And Characteristics Of WANs Information Technology Essay A Wan is a large area network that expands in a geographical area, such as a country or a continent. It is known also as a communication system that connects computer networks such as LANs (local area network) and MANs (metro area network). The connections go through local, national or international areas public or privately, using generally phones lines, referred to as POST, or employing PSTN (public switched telephone network) or fibre optics, creating the link between networks located in different facilities. A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances. These networks contain a collection of machines to execute some programs which are called hosts. These are connected to networks that have communication through routers with each LAN and a WAN interface. Remote access is something vital for the companies and users because it allows you to have mobility and work through different areas. Also it gives the benefit to get better business out of your area. Basically a WAN generates new applications viable, and some of them can cause important effects in whole society. In order to give some idea of important uses, some of them they are already commented before, we can see emphasize: The access to remote programs. The access to remote data bases. Facilities of added value communication. The principal components are routers, switches and modems. Devices on the subscriber premises are called customer premises equipment (CPE). The subscriber owns the CPE or leases the CPE from the service provider. A copper or fibre cable connects the CPE to the service providers nearest exchange or central office. This cabling is often called the local loop, or last-mile. Then Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud. Types and characteristics of WANs: The local area networks (LAN) are significantly different from the wide area network (WAN). The LANà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ sector is one of the fastest growths in the industry of the communications. The local area networks own the following characteristics. Generally, the channels are property of the user or company. The connections are lines (from 1 Mbps to 200 Mbps). The DTEs is connected to the network via channels of low speed (from 600 bits to 56 Kbits). The DTEs are near to each other, generally in a same building. A DCE can be used to exchange between different configurations, but they are not as frequently as in the WAN. The lines in LANs are better quality than the channels in the WAN, because to the differences between the local area networks and the wide network area, their topologies can take very different forms. The structure of the WAN tends to be more irregular, due to the necessity to connect many terminals, computers and switching centres. Circuit Switching: The circuit switching is a WAN switching method which establishes, maintains and ends dedicated physical circuit through a carrying network for each session of communication. The switching circuit, which is used widely in the networks of the telephone companies, operates of form similar to one circuit, which is widely used in telephone company networks, operates similar to a normal telephone call. ISDN is an example of a circuit-switched WAN technology. Connections circuit switched one site to another are triggered when necessary and generally require low bandwidth band. The circuit switched connections are used primarily to connect remote users and mobile users to the corporate LAN. Also it is used as backup lines to circuit higher speeds, such as Frame Relay and other dedicated lines. One advantage is it is highly reliable for its function. A disadvantage is all the time spends to set up the channel and also there is the single point failure which can cause a dis ruption in communications. Message Switching: a computer is in charge to accept connected traffic of networks to him. The computer examines the direction that appears in the head of the message towards the DTE that must receive it. This technology allows recording the information to take care of it later. The user can erase, store, route or answer the message of automatic form. Picture taken from technet.microsoft.com Packet Switching: In this type of network the data of the users are disturbed in smaller pieces. These fragments or packages, you are inserted within information of the protocol and cross the network like independent organizations. Connectionless and Connection-Oriented Services: they happen directly of the free situation to the way to transfer data. These networks do not offer confirmations, flow control and neither recovery of errors applicable to the entire network, although these functions if they exist for each particular connection. An example of this type of network is Internet. In connection-Oriented packets switched, the multiplexing concept exists in channels and ports are known as virtual circuit or channel. The user pretends to have a dedicated resource, when he shares with another one then what it happens is that they take care of bursts of traffic of different users. General routing issues Congestion is about too much presence of packages in a part of one subnet. In cases of extreme congestion, routers start to reject packages, decreasing the system performance. The reasons of congestion are many, some of them are: If in 4 lines, the information arrives to him at router and all needs the same line of exit, it exists competition. Insufficient amount of memory in routers. But if you add more memory, this just helps until certain point because the time to arrive at first from the queue can be so long. Slow processors in routers. The analyse process of the packages are expensive, so slow processors can cause congestion. In that way the congestion propagates to the others routersà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚ ¦ The flow control and the control of congestion are not the same: Flow control: is in charge of a fast emitter does not saturate to a slow receiver. Control of Congestion: its function is to try to avoid that the network is overloaded. The solutions for the problem of congestion can be divided in two classes: Open Loop: They try to solve the problem with a good design. They use algorithms to decide when to accept more packages, when to discard them, etc. But they do not use the actual situation of the network. Closed Loop: The solution in this case is based on the feedback of the line. Generally they have three parts: 1. The system is monitored to detect when and where it happens the congestion. 2. This information goes towards where actions can be taken. 3. The operation parameters of the system adjust to correct the problems. Several measures of the performance can be used to measure the congestion. The main measures used are: % of discarded packages, Queue length, Number of packages that makes timed out and/or relayed, the average delay of the packages. 3. Addressing and routing It is necessary that any machine or host have one address, in order to get the information to the network. In the case of Internet, this are called IP address, and to each machine of the Network is assigned one. An IP address is a 32 bit number represented as four octets. Each of these four octets is in the range between 0 to 255. Class A: 10.0.0.0 a 10.255.255.255 (8 bits red, 24 bits hosts) Class B: 172.16.0.0 a 172.31.255.255 (16 bits red, 16 bits hosts) Class C: 192.168.0.0 a 192.168.255.255 (24 bits red, 8 bits hosts) Class D addresses are used for multicasting Class E is for experimental purposes.

General Information And The History Of Beer

General Information And The History Of Beer Beer is the oldest and most widely consumed alcoholic drink in whole world and the third most popular drink overall after water and tea. Beer is produced by the brewing and fermentation of starches, mostly produced from cereal grains and usually malted barley, and also wheat, corn wheat and rice may be used as well. Almost all beers are flavored with hops. Hops are also used to add bitterness to the beer and be as a natural preservative. Although there are deferent beers with flavored with herbs or fruit smell. Beer has appeared between 9,000 and 14,000 years ago, being as old as the civilization. Beer is one of the oldest products of civilization, and may even have been a stepping-stone to the invention of leavened bread. The grain, from which beer is made, was the first domesticated crop that started the process of farming during the nomadic times. By that time the beer was cloudy and not filtered, and people were using à ¢Ã¢â€š ¬Ã… ¾drinking straws when drinking beer, in order to avoid brewing residue in the mouth (Wikipedia, 2011). In ancient times beer was mostly used as barter, instead of being sold and a Babylonian King had even introduced a daily norm of beer per day. A normal worker received 2 liters, civil servants 3 liters, administrators and high priests 5 liters of beer per day. The Egyptians also have taken part in the history of beer brewing. They have been experimenting with unbaked bread dough and were improving the taste of beer. Beer is an especially important drink in countries such as Belgium, Germany, Ireland , and the UK, with nations such as France, the Scandinavian countries, the Czech Republic, and others having strong and unique brewing traditions with their own history, characteristic brewing methods, and styles of beer producing. RELATION BETWEEN GERMANY AND BREWING The most widely known event in the history of brewing is the establishment of standards for brewers by the Germans. They decided that to the production of beer, only four ingredients should be used: water, malted barley, malted wheat and hops. It is emphasize that beer was for the first time brewed on German soil. Germans brewed beer not just for God sacrifices, but also for their own enjoyment. Germans started to open even brewery family businesses. Beer is in Germany a major part of their national culture. Germany has more breweries than in any other country. There are almost 1,300 businesses producing beer. Figure 1 German Beer Statistics % Age of European Production: 26.5% Total beer consumption: 107,800,000 hectoliter Consumption per head: 131.7 l Number of breweries: 1294 Beer exports: 8,539,000 hectoliter Beer imports: 2,168,000 hectoliter Draught beer percentage: 22% Notes: The only countries with which Germany has a trade deficit in beer are Belgium, the Czech Republic and Mexico. MARKET STRUCTURE On the one hand, Germans are beer drinking nation. Their consumption per/capita is almost 60% higher than the western European average consumption and the beer market from Germany is still the largest in the world. Even if there are 1,300 breweries in Germany, therefore Germanys beer market is highly competitive. Their output is only around a third of the whole beer production in EU. On the other hand German consumers started to move away from the alcoholic drinks, the desire of a healthier way of leaving is rising, and German is tend to consume more mineral water, juice and coffee. The result of this is 7% drop in the beer consumption in Germany since 1998. Even though Bavarian-style beer continued to grow, and beer-based mixed continue to have high demand. Young generations of consumers are trying to discover new and different types of drinks, such as beer mixed with lemon-lime soda or cola etc. Imported beer is account only 5, 9% of the total beer consumption in Germany. This is due to the fact that domestic breweries created a strong preference among the consumers. The import share remains more or less constant in spite of several major international breweries that previously sold their products through exports now producing under license in Germany. Pils is the dominant segment in Germany with a market share of some 60% in total. In addition, there are a number of special German beer types such as Weizen, Alt and Kà ¶lsch. EVALUATION OF MAJOR BREWERY COMPANIES IN GERMANY BECKS BREWERY is a brewing company in the north part of Germany, in city of Bremen, since 1873. Becks was first owned by a local family, and later it was sold to InterBrew. Becks beer is famous of it quality and world-wide known brand, drunk by millions of consumers every year and is ranking number 5 among the most selling beers in Germany. By exported volume, Becks is on the first place among German Beers, and it is sold in more than 100 countries in the world. The largest markets for Becks outside Germany are the United Kingdom, the USA, the Ukraine, Australia, Italy, Romania, and Russia (Brauerei Beck Co, 2011). Products of Becks Brewery Becks the main brand, a pilsner Becks Blue (Alcohol Free) Becks Premier Light Becks Gold Becks Green Lemon Becks Green Lemon Alcohol Free Becks Chilled Orange Becks Level 7 Becks Ice Becks NEXT Becks Dark Becks Oktoberfest Becks VIER Becks Brewery is an attraction of the city, because the company organizes tours in the inside the brewery and gives sample of finished products and afterwards visitors can enjoy food at the Becks cafà ©, or browsing for beer-related souvenirs. Besides the organizing tours, the company also uses other ways to advertise its products. The sponsor various sport events, festivals and have more advertisements on TV and magazines. OETTINGER BREWERY is the best selling beer brand in Germany since 2004 with an output of almost 6.61 million hectoliters sold annually. Moreover a big factor that contributes to this big amount of sales is the low-price strategy. Oettinger appeared in the market, by using a gap from it industry. The brewery started to sell cheap beer in big volumes, so that people would afford it and would have a beer they just wanted for the lowest price and relatively good quality. In order to avoid competition, Oettinger bought the beer brand 5.0 Original and the corresponding brewery in Braunschweig. Braunschweig was his competitor, a brewery from the same segment of market (The Oettinger Group, 2011). Oettinger uses different ways to maintain the beer price as low as possible: No advertisement and promo campaigns. Concentrating only one the one brand, compared to other breweries which have twenty and same times even more brands. Direct delivery from brewery to stores, no intermediaries. The brewing process is highly automated only few employees are needed for production. PORTER 5 FORCES ANALYSIS Force 1: Supplier power Suppliers have small bargaining power in the brewing business, which works in technique brewers goodwill. There are a lot manufacturers and suppliers who provide brewing equipment. Brewers can also buy used or refurbished already existing equipment. Many of the companies that supply brewing equipment do not focus just on that area, they also offer other products and services and the brewing equipment is just one phase of their operation. Supplier concentration is low, which can possibly increase the sustainable profits. As far as supplier substitutes, the ingredients that go into the brewing of beer cannot be replaced. Those ingredients are necessary for the production. Brewing must have malt, hops, barley, yeast, and water. The beer brewing industry relies heavily on supplier input. Especially the ingredients that are in beer, consequently the suppliers are in constant need to keep this industry operational. Which means there is a threat of supplying integration; the larger brewing companies produce enough capital to possibly buy plots of land to grow their own malt, hops, or barley (Beer Brewers Industry Analysis, 2008). Force 2: Buyer power The main buyers of beer in the brewing industry are distributors. There are over 1,900 beer distributors nationwide servicing approximately 320,000 retail businesses. Bargaining power of buyers increase when: there are few distributors in the market; the distribution industry is increasing very fast than the manufacturers industry; and when new competition cannot emerge. The distributors are the ones with all the connections to the consumers retailers, thus the distributor control the prices based on what income margins they require. The distributors are consolidating and increasing in power. Moreover, distributors are limiting new competition. So, overall the Porters force of Buyer Power is a negative for the Beer Brewing Industry (Beer Brewers Industry Analysis, 2008). Force 3: Substitutes Figure 2 Beverage Consumption Category % Of Beverage Consumption Soft drinks 49.0% Beer 19.4% Fruit beverages 13.2% Bottled water 12.2% Sports drinks 1.8% Wine 1.7% Rtd tea 1.6% Spirits 1.1% Total beverages 100.0% Beer has a lot of substitutes as you can see from Figure 2 some of them are wine, spirits, wine cooler, and specialty drinks. But also soft drinks, water, fruit juices, tea, and sports drinks may be considered as its substitutes. According to the figures from the Beverage World Publications Group, Beer constitutes for 19.4% and soft drinks account for 49.0%. This makes beer consumed more than bottled water, fruit juices, sports drinks, wine, spirits and tea. These factors increase the threat of substitute goods for the beer industry, which has a negative effect on industry profits (Beer Brewers Industry Analysis, 2008). Force 4: Rivalry Rivalry is the extent to which companies compete with one another for customers. Rivalry can be price-based or non price-based (Michael Porters Five Forces, 2009) Rivalry is measured by the concentration level of the industry; the more concentrated the industry, the less rivalry. Other factors that increase rivalry are large capital asset requirements and high switching costs. This industry is experiencing significant concentration effects, which decreases rivalry. Also, there are significant barriers to exit, which increases rivalry. The proposed joint venture MillerCoors would act to decrease rivalry overall. Therefore, the overall effect of rivalry on this industry is neutral (Beer Brewers Industry Analysis, 2008). Force 5: Entry Barriers In the Germany beer brewing industry there are a substantial amount of entry barriers that protect the firms currently in the industry from the new entrants. Price competition combined with increasing vertical integration and the inherent production economy of the market leaders makes it very difficult for an inefficient major brewer to compete on a national scale. (CNBC, 2011 Liquor Sales Slow Along With Econom) Overall the German brewing industry faces a large amount of barriers to entry as there are economies of scale, brand loyalty and large capital requirements, product differentiation effects, possibly limited access to distribution channels, and large amount of government regulations. All of these factors reduce the threat of entry into the national beer brewing industry which in turn raises the industrys potential for sustained profits (Beer Brewers Industry Analysis, 2008). 5 FORCE SUMMARIES Force Key Drivers Effect on Industry Profit Bargaining Power of Suppliers Small suppliers relative to brewers + Bargaining Power of Buyers Consolidation of industry; distribution connected to retailers Substitutes Growing substitute industry; low switching cost Rivalry High concentration; high innovation Entry Barriers High capital requirements, economies of scale, closed distribution channels, high government regulation. + Conclusion In conclusion I would like to emphasize that beer market in Germany is very product differentiated and diverse. The competition forces are high and in parallel, customers have different offers from what to choose. Germany is the biggest exporter of beer in the world and has the most breweries. Beer has various substitutes, even though it is on the second place among other drinks. Each brewery is trying to gain competitive advantage. Oettinger lowers the prices and Becks uses more advertising channels.

Why is the Novel Called To Kill a Mockingbird? Essay -- To Kill a Mocki

Why is the Novel called To Kill a Mockingbird. In order for us to understand the reason why the novel is called "To Kill a Mockingbird", we need to take into account what the title actually means. The mockingbird is a type of finch, and it gets its name from its ability to make sounds that mimic other animals. This bird is not a predator and all it does is to make music. In the book the references made to the mockingbird are ones of great significance. The first time we come across this in the novel is when Atticus Finch says to his son Jem Finch, "Shoot all the bluejays you want, if you can hit 'em, but remember it's a sin to kill a mockingbird." The children, Jem and his sister Scout do not, at first, understand the importance of this advice. They decide to ask their neighbour, and also good friend, Miss. Maudie about it. She starts off with "Your father's right," and this is not the only time in the novel when she is in agreement with Atticus' views. She is almost a mother figure to the children along with Calpurnia, who is their cook, and she reinforces Atticus' philosophy. In this instance what she tells the children about mockingbirds, reinforces Atticus' views. She says: "Mockingbirds don't do one thing but make music for us to enjoy. They don't eat up people's gardens, don't nest in corncribs, they don't do one thing but sing their hearts out for us. That's why it's a sin to kill a mockingbird." At this point the writer is conveying to us that it is a sin to kill a mockingbird, the reason being that it does not do anything but make music. Mockingbirds are portrayed as the epitome of innocence. The killing of an innocent is always seen as a horrendous crime in any age and any time. As we re... ...ole point that the novel is trying convey is about tolerance and understanding. It is due to a lack of these things that we get prejudice and discrimination of any kind occurs, whether it is racial or because of gender. If people were tolerant of other people then these problems would not even arise. Atticus is right when he tells scout that to truly understand a person you need to walk in their shoes. By doing this you will understand the person and so will be able to tolerate the person without fearing them because they are different to yourself. Atticus is not the only person in this novel who is able to think ahead. We know that people like Miss Maudie and Heck Tate, the sheriff, are also able to think beyond racial lines. We have come a long way from then, in establishing equality, and yet we still have a long way to go in achieving the perfect world.

Analysis of Just and Unjust Wars: A Moral Argument with Historical Illu

Analysis of Just and Unjust Wars: A Moral Argument with Historical Illustrations Michael Walzer first wrote Just and Unjust Wars: A Moral Argument with Historical Illustrations in the years following the Vietnam War, and unfortunately its premise on morality in war will always remain as relevant as it was then as it is now, with conflict between states forever existing. Michael Walzer is one of the most prominent social critics in North America and in this book, he explores two main concepts, the justice of war and the justice in war in a great depth, and uses numerous historical references to support his claims. It is a very well configured piece, written in such a way of persuasion that your personal view on morality in war may ultimately change after delving into thoughts for several hundred pages. To an overwhelming majority of people, the words ‘war’ and ‘morality’ have seemingly opposing meanings, however in the preface to his book, Walzer points out that "whether or not its specific terminology is adapted, just-war theory has always played a part in official argument about war" (Walzer XI). He proceeds to discuss in a greater detail the ways that war has been perceived and how this impacts the topics of war and morality, and in doing so, he provides an intelligently structured and persuasive argument that can be viewed within a moral context. He addresses this topic both from the view of the role of the state and also from the perspective of how the decision to fight impacts the individual. Walzer takes the position that an individual should fight only for private and personal reasons rather then from nationalistic feelings because he feels that it is crucial that this decision should be freely chosen and that it constitutes one of the crucial requirements for a ‘just’ war. Walzer defines a ‘just war’ as a ‘limited war,’ and that just wars are governed by a set of rules, designed to prevent, as much as possible, "the use of violence and coercion against non-combatant populations" (Walzer XVII); On the other hand, a limited war attempts to establish the way things were prior to the aggression taking place. Aside from extreme cases, just wars do not have legitimate reasons for reaching beyond this goal, including the replacing of the aggressor’s... ...f becoming aggressors themselves. As Walzer points out, the Kuwait regime that US intervention restored to power was little better for the Kuwait people than their Iraqi invaders. However, the ultimate fate of this regime was placed back in the hands of the Kuwaiti people disregarding our attempt at improvement. Reading this book was both uplifting, in that Walzer does an excellent job of developing a framework to understanding what should and should not be done during wartime, as well as depressing, in realizing that war will only evolve and forever exist. The limits that a ‘just’ war places on the use of aggression between states for both states and individuals, according to Walzer, offers a rational and moral way of perceiving modern warfare. He ends his text with the comment that "The restraint of war is the beginning of peace" essentially summing up his argument, though will this ‘end’ ever arrive? (Walzer 335). This book offers a sane way of perceiving morality within the insanity of war. Work Cited Walzer, Michael. Just and Unjust Wars: A Moral Argument with Historical Illustrations.

Computer-Mediated Versus Face To Face Communication :: Essays Papers

Computer-Mediated Versus Face To Face Communication The invention of the computer changed the face of interpersonal communication forever. The Internet has contributed even further to this change. Through the Internet we can communicate with others online, through text, in almost any part of the world at any time. This is called computer-mediated communication and has become a major part of our lives. In many cases, people communicate by computer more than face to face or by phone. Is this a good thing and is communication in our society heading in the right direction via computer? Researchers have different views on this matter because there has been research done to indicate that computer-mediated communication can be both good and bad. The question then arises, who is right? A closer look at the two sides of the matter should help shed light on a more concrete conclusion. There are many people who attribute anxiety to face-to-face communication. These same people often find it much easier to communicate by computer. According to research published in "Communication Research Reports," through computer-mediated communication, apprehensive communicators have an advantage in that it may nullify certain features of communication contexts that tend to heighten anxiety (Patterson). Research shows that computer-mediated communication acts as a mitigating variable with regard to status differentials and it reduces evaluation fears that lead to communication avoidance and withdrawal (Gojdycz). This means that CMC, computer-mediated communication, allows us to communicate with one another without placing specific labels on the people we are communicating with such as race, age, physique, or even the sound of their voice. Why is this important? These labels often act as barriers to our communication. Many people find it difficult to communicate with others unlike themselves and this barrier is removed during CMC. In CMC, people have the choice of what to reveal about their appearance and they are not bound to it as they often are in face-to-face communication. Others tend to feel very differently about computer-mediated communication. In an article in "Communication Education," researchers came to very different conclusions about computer-mediated communication and it's effects. These researchers point out that when using CMC we lose a lot of social interaction. For example, when chatting or e-mailing someone you do not get the benefit of seeing their body language or hearing their tone of voice. This is a concept known as "cues filtered out" and it plays a major role in the opposition of CMC.

An Interpretation of John Keats’ To Autumn Essay

Introduction Poems by John Keats are a source of inspiration. He plays with his readers and takes them to places and times with his words. What inspiration does Keats bring? He inspire his readers to go beyond his words and discover a new world he creates. He makes his words so colorful and alive it is almost musical to the ear. When one reads Keats, he wonders what’s in his heart when he wrote his particular poem and makes him want to be in Keats world and senses. In this particular review, I tried to see Keats world of autumn from afar. A world detached, to objectively examine and look at autumn as Keats paints it with his words. I also wanted to get a perspective of Keat’s style with words, of how he uses them as a vehicle for others to journey to his world. In this same review, I tried to experience the world that Keats created and feel both the experience of his symbols and my comprehension of what he symbolizes autumn to be. The formal and thematic aspect of the poem will be commented on but this interpretation will be candid as I believe Keats wanted his poem read. 1 2 Throughout the three stanzas of the poem, Keats has maintained the ten syllable measure of each line, although, the foot measure of syllable stressed is a little slacked. As in the lines, â€Å"Who hath not seen thee oft amid thy store? Sometimes whoever seeks abroad may find† and some more. Reading aloud the verse, Drows’d with the fume of poppies, while thy hook spares the next swath and all its twined flowers: I could not quite place the stress of the syllables to create a rhythmic sound. I call it literary license, Keats permit his reader to make a decision and choose the way to vocalize his poem. The first stanza is vibrant and tells us of bounty. It is a direct contradiction of autumn or fall as the season is the time when trees begin to bare its leaves and fruits are scarce. But in this poem, Keats describes autumn as the climax of summer, †Season of mists and mellow fruitfulness, Close bosom-friend of the maturing sun;† mist and mellow here are used as a welcoming scenario to a world filled with life and produce. The last word of the first line fruitfulness rhyming with bless on the third line and sustaining the rhythmic scale throughout the stanza gives a musical air as one reads the poem aloud. The stanza tells us also of a promise of continuity. â€Å"To swell the gourd, and plump the hazel shells with a sweet kernel; to set budding more, and still more, later flowers for the bees,† true to the rhythm of his verses, Keats described autumn as a time when seeds are planted for life to continue. It tells as of a beginning of a season, fresh and ready for a new experience in a manner where the season before it, which is summer, in the festivities of plenty and not as a dying season ready to be forgotten and left behind. Autumn in Keats† dedication receives Summer’s gift of plenty, it began as a climax of summer and therefore, promise to be a season 3 of new discoveries and not as bleak as shedding away the leaves of trees to forgetfulness. In the second stanza, the word flowers does not rhyme with any other words at the end of each line. I need to read the poem aloud and discover a rhythm for it to make the poem alive, it gets into a perfect rhyme with the word â€Å"spares’ if that’s where I put the measure at the end of the first line, thus, â€Å" Drows’d with the fume of poppies, while thy hook Spares / the next swath and all its twined flowers.† The same with the last two lines of the second stanza, â€Å"Or by a cyder-press, with patient look, Thou watchest the last oozings hours by hours,† by simply repeating the word, the seemingly ignored rhyme is captured. This is my personal preference of setting the rhythmic pattern of vocalizing the poem, although, the rhyme pattern of the three stanzas comes out to be ababacacaaa, ababcdecdde, and ababcdecdde, in this particular order. It can be observed that the first stanza follows an independent rhyme pattern from the other two stanzas. Keats may have done it intentionally to stress the change of tone of the second stanza that is presented as a question. Why could Keats have done this? As I get absorbed in the autumn scenario of the first stanza, feeling the cool air and seeing laden apple trees bend, the mossed cottage, the vines and more, feeling the climax of summer shared into the start of autumn, and as I get lost to the world that Keats painted with his words, somebody shoots a question like, †Who hath not seen thee oft amid thy store?† and I was reminded that I am not alone. It was not even a question in the sense that Keats emphasized the beauty of the season being one that cannot be ignored. If he likened autumn as a stage of life’s journey and we choose the paths that we travel on, in the roads we took as we travel in this world, we met people to keep us company, 4 sometimes partway, the greatest thing maybe is to find beauty in life that keeps us company all through the journey. Reading the second stanza brings another question to my mind. What do I really seek for in this life? Why does Keats made me ask this when he wrote, â€Å"Sometimes whoever seeks abroad may find Thee sitting careless on a granary floor,† What Keats said in this line is that there are people who sought for things in this life away from where they really are and in fact, what they are seeking for is just within reach. Very clearly he meant happiness, he meant beauty of living, the beauty of living in the here and now. Keats wanted to tell his readers that we need not wait for what we can achieve in the future to experience the joy of being alive. We need only to be aware of the blessings we could find in the present to feel that joy that we seek for in our journey. The third stanza is a validation of the second stanza both in form and interpretation. I noticed that both have the same rhyme pattern and both starts with a question. It tells us of men looking out for joy too far out as in spring in autumn failing to notice that joy is just within reach. â€Å":Where are the songs of spring? Ay, where are they?†, Keats wanted us to know that in this life’s journey, happiness is not about the things we reap in the future but of finding happiness in every endeavor that we do without waiting for whatever fruits or rewards we earned as a result of our works. He tells us that like spring or summer or winter, autumn carries within itself its own music like the wailful choir of small gnats, the loud bleats of full-grown lambs, the songs of crickets, the whistles from garden croft, the twitter of the swallows. Keats wanted his readers to discover them. The choice of the word â€Å"wailful†, the reader can almost hear the liquid fall of tears of the gnats† mournful music. Sad, yet in Keats world of words 5 they represented life’s emotions that eventually gives meaning to everyone’s existence. He pictures autumn’s soft dying day with rosy hue and not with the bleak grey or the dying blackness of the welcoming dark, but of shades of the rose, full of life, full of promise, perhaps of another day ahead, a goodnights sleep, a beautiful dream, a walk in the moon? Or whatever the good life brings in the third part of man’ life. The poem is not necessarily strict with the academic form of the poem although as much as possible Keats wanted to adhere to the scholarly it dictates. In this form, the poem creates a character of free spirit and that refused to be tamed. The three stanzas o f the poem expresses a discipline. It follows a form respecting rhyme, measure, rhythm, color, and all the constituents of this form of literature. Yet, it does hesitate to lay away the conventional to express the soul of his expression as Keats diversion from the rhyming pattern to the rhyming pattern he followed on the second and third stanza. The syllabic measure of the words spares and flowers are left to the decision of the reader, making the reader an active participant to the interpretation of the poem. The three parts of the poem suggest the three stages of man’s life at a point of view, being at birth and early life, maturity and finally at the golden old age of man. But Keats only suggest, because all three speaks of seeking the joy of finding the beauty that life brings. The poem itself, as a form, is music to the ears. His play of rhythm, rhyme, and choice of words, in the context of emotionally attaching the self during its vocalization is like listening to the music of nature. The poem vividly expressed the colors of autumn using nature’s characters as in â€Å"rosy hue†. It does not boast with lengthy lines, numerous stanzas, academic words to express the simplicity of enjoying life, in life’s term. 6 Conclusion The poem â€Å"To Autumn† is a metaphor. Keats represented the season as man’s objects of his endeavors. In the same manner, the times of the seasons’ days represented man’s three stages in life. Why has Keats chosen autumn to represent ingredients of life’s journey? Maybe because of the colors it creates as the season journeys towards another. Maybe because autumn carries with itself the fruitful harvest of summer and links itself to the preparation winter does for a new life in spring. All these are speculations, and these speculations made me look into my life and my attitudes towards life as a journey. A lot of interpretations had considered â€Å"To Autumn† as one of the greatest odes that Keats had written. â€Å"Written in September of 1819, this piece is regarded as his most achieved ode.† 1. If all forms of writing, in different degrees of exertions aims to manipulate the reader’s mind to a certain mode of thoughtfulness, then Keats’ has manipulated mine into a romantic mode of communing with nature as a tool of reflection. He has vividly painted a picture of a season with words so successfully so that its form takes life and invited its readers to experience the joys of the season. It invited everyone to forget about worrying so much about future and take the joys of life in the here and now. 1 Analysis of Keats’ Poem To Autumn Essay. http://exampleesays.com/viewpaper/?wid=1795
