Chem Lab Mixtures Essay

In this lab, a mixture of naphthalene (C10H8), common table salt (NaCl), and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. The three objectives in this lab were 1. Learn the different separation techniques which include; sublimation, extraction, decantation, filtration and evaporation. 2. Separate three components in a mixture using the separation techniques learned. 3. Determine the mass percentages of each of the three components present in a mixture. The 5 separation techniques are†¦Ã¢â‚¬ ¦ 1) Sublimation: involves the heating of a solid that passes directly from the solid phase into the gaseous phase. The reverse process where a gas goes into the solid phase is called deposition or condensation. 2) Extraction: involves using a solvent that selectively dissolve one or more components from a solid mixture. 3) Decantation: involves the separation of a liquid from insoluble solid sediment by carefully pouring the liquid from the solid without disturbing the solid. 4) Filtration: involves separating a solid from a liquid through the use of a porous material such as filter paper. The porous material allows the liquid to pass through it but not the solid. 5) Evaporation: involves the process of heating a mixture in order to separate a volatile liquid in the form of a vapor, while the remaining component dry. The mixtures that will be separated are naphthalene, common table salt, and sea sand. The separation of this mixture involves three steps which are heating the mixture to sublime the naphthalene, then dissolving the table salt with water to extract and evaporating water to recover dry NaCl and sand. To determine the percentage of each component in the mixture, this formula can be used. % component= grams of component isolated grams of initial sample PROCEDURE: A. Preliminary Steps 1. Obtain a clean, dry 150-mL beaker and weigh it to the nearest .001g. 2. Obtain a sample of the mixture from your instructor and carefully transfer 2g of the mixture into the beaker. 3. Record the weight of the beaker with the mixture inside to nearest .001g and calculate the exact weight of the mixture by subtraction. B. Sublimation of Naphthalene 1. Set up and do the sublimation in the hood. 2. Place an evaporating dish with some ice on top of the beaker containing the mixture and place the beaker on a wire gauze with an iron ring and ring stand assembly. 3. Carefully heat the beaker with a Bunsen burner until vapors appear in the beaker. A solid should collect on the underside of the evaporating dish. Continue heating for 10 minutes. 4. After 10 minutes, remove the Bunsen burner from under the beaker and then remove the evaporating disk from the beaker and collect the solid by scrapping it off the dish with a spatula onto a weighing paper. 5. Stir the contents of the beaker with a glass rod. Return the evaporating disk to the beaker and apply the heat again. Continue heating and scraping off solid until no more solid collects. 6. Weigh all the naphthalene collected and record it on the Report sheet to the nearest .001g. 7. Allow the beaker to cool and then weigh the beaker with the contained solid. Record the weight of the naphthalene sublimed by subtracting the weight of the beaker with remaining solid after sublimation from the weight of beaker 1 with original mixture. C. Separation of the Water Insoluble Solid 1. Add 25mL of distilled water to the solid in the beaker. Heat gently and stir continuously for 5 min. 2. Weigh a second clean, dry 150-mL beaker with 2 or 3 boiling stones to nearest .001g and record its mass onto the data sheet. 3. Assemble the apparatus for gravity filtration as shown in Figure 3.4 4. Fold a piece of filter paper according to the technique in Figure 3.5. 5. Wet the filter paper with water and adjust the paper so that it lies flat on the glass of the funnel. 6. Position beaker 2 under the funnel and pour the mixture through the filter, first decanting most of the liquid into beaker 2 and then transferring the wet solid into the funnel. Collect all the liquid in beaker 2. 7. Rinse beaker 1 with 5-10-mL of water, pour over the residue in the funnel and add the liquid to the filtrate. *Repeat this step once more. 8. Place beaker 2 on the wire gauze with an iron ring and ring stand and heat using the Bunsen burner. As the volume of liquid is reduced, sodium chloride will appear. When the liquid is fully evaporated, allow the beaker to cool d own. 9. Weigh the beaker, stones, and the solid residue to the nearest .001g. Calculate the weight of the recovered NaCl by subtraction. D. Drying the Sea Sand 1. Weigh a third dry 150-mL beaker and transfer the sand from the filter paper to beaker 3. 2. Place beaker 3 with the sea sand on the wire gauze with an iron ring and ring stand and heat the sand to dryness. When dried, the sand should be freely flowing. 3. Allow the sand to cool to room temperature. 4. Weigh the beaker and the sand to the nearest .001g. 5. Calculate the weight of the recovered sand by subtraction. Results and Discussions: In this lab certain separation techniques were used and learned. When measuring the different amounts of the three components of the mixture, all measurements were based on significant figures. Thus, each certain digit plus one uncertain digit was included in all measurements. First, the sublimation of naphthalene was done by heating the mixture. The original weight of the naphthalene collected was .070g and after sublimation the weight of naphthalene was .095g. Next, extraction was observed in separation of the water insoluble solid. The NaCl was separated from the SiO2 because of the solubility of NaCl in water and the insolubility of SiO2 in water. Solubility is the ability of a substance to dissolve when in the presence of a certain solvent. The NaCl was said to dissolve leaving only the insoluble sea sand in the beaker with the water. Filtration was also observed in this experiment when the piece of filter paper was wetted and used for gravity filtration. The NaCl dissolved in the water, and by decantation, the process of separating a liquid from a solid by gently pouring the liquid from the solid so as not to disturb the solid, the NaCl solution was separated from the SiO2. Heating can cause substances to evaporate, which represents a change in state, so the water was evaporated from the NaCl, which left behind the solid NaCl. The amount of NaCl in the experiment was measured to be 0.822g, but the origi nal sample with the weight of the beaker included actually weighed 65.001g. Then, the remaining component of the mixture, SiO2, was measured to be .927g once it had dried out. Originally the weight of the beaker and SiO2 was 67.078g. The comparison between the measured masses of the three different substances in the mixture and the actual masses of the components proved that the substances of mixtures are able to separated, yet still retain their chemical and physical properties. After the components of the original sample were successfully separated, their weights were added together. The measured total weight of the three separate components of the recovered solids was 1.844g. The percentage yield and percentage of all the substances was found. The percent yield was found by dividing the mass of the recovered solids by the mass of the mixture, then multiplying the answer by 100. The percentage yield for this experiment was 88.314%. The makeup of that 88.314% is divided between naphthalene at 4.550%, NaCl at 39.368%, and sea sand at 44.397%. Sources of Error: Ideally, the total percentage should have been 100%, because substances are neither created nor destroyed during these physical separation methods but due to minor errors such as incorrect measurements, could have caused this slight deviation from the actual total. One possible lab error that may have affected this outcome is that some amount of naphthalene may have been lost to the air, thus resulting in a lower calculated mass. or because there was not enough ice on top. It can also be possible that accurate weighting measurements of the mixtures were not taken. Sample Calculations Weight of naphthalene after sublimation =(weight of beaker 1 and mixture) – ( weight of beaker 1 and solid after sublimation) (68.239)-(68.144)= .095g Percentage yield= (grams of solid recovered/grams of initial sample) x 100 Percentage of naphthalene: (1.844/2.088)x100= 88.314% Conclusions: The main concept I learned that was being applied and studied in this lab was that mixtures can be separated into their components by physical means. The purpose of the lab is to become familiar with the methods of separating substances from one another using decantation, extraction, and sublimation techniques. Mixtures occur in everyday life in materials that are not uniform in composition. It is a combination of two or more substances. Mixtures are characterized by the fact that each of the substances in the mixture retains its chemical integrity, and that mixtures are separable into these components by physical means. In this lab, the starting point was a mixture of naphthalene, NaCl (sodium chloride), and SiO2 (sand). In the lab, it was determined that naphthalene can be sublimed from the mixture without having an effect on the other substances. It was also realized that NaCl is water soluble, while SiO2 is not water soluble. Since the SiO2 is not water soluble, is would remain a fter the water with NaCl was decanted.

Harry Potter and the Philosopher’s Stone Essay

First published in England in 1997 as Harry Potter and the Philosopher’s Stone, the book quickly became wildly popular. The next year saw its publication in the United States, this time titled Harry Potter and the Sorcerer’s Stone, receiving critical acclaim and several awards. I would rate this book 9 on a scale of 10. Both the Carnegie Medal and the Newberry Medal awards consider plot and character development when judging books. Harry Potter and the Sorcerer’s Stone clearly meets those criteria. As the novel unfolds, the reader discovers the information about the wizarding world along with Harry. Characters grow and become more than flat stereotypes – Hermione’s change from bossy know-it-all to genuine friend and partner-in-crime is just one example. The dialogue between characters is believable and Harry’s inner thoughts serve as further exposition without slowing down the action. The novel is long in getting started, which makes sense because the author has to set up a story that will continue over six more books. New readers just have to make sure they keep reading and not quit out of boredom. The illustrations at the beginning of each chapter are good for prompting the reader’s imagination. I would have liked to have seen a few more scenes with illustrations, however. Among them would be a drawing of the Sorting Hat, perhaps as it sat on Harry’s head; an illustration of the dead unicorn in the forest with the frightening creature drinking the blood; and a picture of at least one of the scenes of the children getting past the spells guarding the stone. The chess game would have made an interesting illustration. Besides Mary Grandpre, I think Ludwig Bemelmans, who wrote and illustrated the Madeline books, would have done a good job with Harry Potter. His style of pen and ink drawings are simple yet contain a lot of detail and would fit the tone of J. K. Rowling’s books. The first Harry Potter book as well as all the subsequent books were huge best-sellers. In fact, it was this series that prompted the New York Times to create a separate list for children’s books since Harry Potter monopolized space on the existing top-ten list. But beyond popularity, Harry Potter and the Sorcerer’s Stone is a classic children’s book because of its story. The book incorporates a common theme of good vs.  evil with humor, fast-paced action and relatable characters. Fantasy and magic also resonate with children, and Rowling’s books will surely join those of C. S. Lewis and J. R. R. Tolkein as favorites for generations of children. This book makes reference to numerous other works. Dumbledore is a member of the Order of Merlin, an allusion to the King Arthur myth. Goblins and trolls populate the folk and fairy tales of many cultures. The vampire that Professor Quirrell comes from Dracula and werewolves go all the way back to Ovid. Fluffy, the three-headed dog is based upon Cerberus in Greek mythology. The mirror of Erised is similar to the magic mirror in Snow White or the titular looking-glass that Alice stumbles through. Finally, of course, is the medieval legend of the philosopher’s stone and the French alchemist, Nicolas Flamel. Although the U. S. publisher changed the name of the book thinking that American readers would be unfamiliar with the philosopher’s stone, the book kept most of its English-ness. Foremost is the concept of boarding school, which is much less common in the U.  S. Along with that, Hogwarts has houses, prefects and Head Boys, all similar to Eton College and other British public schools. The robes that Harry and his friends wear are like the robes worn at Oxford and Cambridge. But what makes Harry Potter and the Sorcerer’s Stone quintessentially British is the lack of teenage drama found in most American books for children and young adults. Harry and his friends face challenges from , but they never have to deal with underage drinking, teen pregnancy, drugs or gangs.

Current Economic Situation Essay Example | Topics and Well Written Essays - 250 words

Current Economic Situation - Essay Example As a result, the USA witnessed a growth in suburbs. Then the 1970’s recession destroyed the predominantly industrial cities and created a way for the growth of the knowledge sectors and new geographic centers. The economy suffered from the inefficiencies arising from the manufacturing era. The West Coast experienced a boom, but many cities focused on cheap yet appreciating housing, turning it into its main industry. Yet, as Florida (2009) outlined in his article, such development was too one – sided so that once the crisis occurred, the housing markets crashed, as did the local economy’s major industry. On the other hand, places such as New York have survived and will remain centers of innovation and progress. The latest developments have favored flexible, innovative and international labor force. Moreover, areas harboring such labor force are also diverse in terms of the skills and services these individuals provide. Such a labor force creates new ideas and easily takes over the economy once one segment of that economy falters. For example, whereas the finance, housing and industrial sector suffered, academics and scientists benefitted from this crisis, and so did the cities harboring them, thus creating new spatial fixes around which new forms of social structures will form. The social structure will change over the next decade or more. According to Florida (2010), the high paying workers will profit from their creativity just as the workers in the manufacturing areas benefitted after the Great Depression. Moreover, suburbs and their communities will become denser, more diverse and connected, responding to the need for fast communication, production and delivery of ideas. A change in homeownership will arise, where renting will become more widespread, increasing mobility of workers. In short, Harvey (2001) borrowed the term

The Rock and Roll Music Era Essay Example | Topics and Well Written Essays - 1750 words

The Rock and Roll Music Era - Essay Example This "The Rock and Roll Music Era" essay outlines the origin of this genre and how it became popular. Early rock and roll was a fusion of three leading music genres of the time, and these are pop music, western-country music and Rn’Bs; rock and roll grew to phenomenal heights as songs by rock and roll artists such as Little Richard Chuck Berry and Elvis Presley became instant chart hits throughout the world (Welch, n.d). Socially, the rock and roll era was characterized by widespread racial segregation and high racial intolerance between the blacks and the whites in the American society; race mixing was a huge problem due to the racial hostilities that characterized the American society at the time. Economically, America was still recovering from the pangs of both the civil war and the world wars that had caused massive havoc to its economy; even though the situation was slowly getting better and trade was picking up, the American society was still wary over the potential of a n economic relapse. Politically, the rock and roll era was a period in the American history when there were high political anxieties and fears over the possibility and threat of foreign conspirators even though the world wars had just been concluded and calm had returned in the global society. Culturally, rock and roll was an era defined by a fusion of music cultures i.e. rock and roll is regarded as one of the most influential and phenomenal eras of music especially because it was a fusion of the three most popular forms of music. Rock and roll was also popular all over the world because it emerged along with the rise of television and the highly expressive popular youth culture. Until then, people had listened to music through the radio i.e. WLS 890, a radio station that played the most popular songs of the time, about young love and cars in particular; this station was common among the youth of the time. The youth of this era were very expressive and experimental and their teenage angst coupled with their free spiritedness lifestyle was a perennial source of worry to their parents who were wary of the potential ramifications of teenage rebellion in the hostile American society. These teenagers were fast at picking up the rock and roll mannerisms and influences especiall y fashion by watching TV and imitating the rock and roll superstars in their manner of dressing and their tastes in things

Global Leadership and Management Essay Example | Topics and Well Written Essays - 1250 words

Global Leadership and Management - Essay Example The paper tells that the French economy had withstood the economic recession better than most other nations because of the resilience of the domestic spending of consumers, having a large public sector and because it is less exposed to the global demand and thus less exposed to the downturn. However, the GDP of the nation has been contracting since then. GDP contracted by 2.5% in the year 2009. Additionally the unemployment rate has also increased from 7.4% to 9.5% between the years 2008 and 2010. This could be a potential threat for the company seeking to expand in France as it could face inadequate demand for its products. Additionally the labor market in France is not much competitive. That is why the French government has been trying to reform the labor market and modernize the economy. Workers productivity remains low in France. The president of France has tried eliminating the annual flat business tax and has also tried to increase tax credit for the investments made in the sma ll and medium scale enterprises. This could act as a favorable factor for the company trying to expand in France. Moreover France also represents strong presence of labor unions which and the French Government pays particular attention to the protection and safeguard of workers both in the public as well as the private sector. This could be detrimental for the company to take strategic actions in case of low productivity of workers or the organization. (Central Intelligence Agency, 2011). Strategies to address the issues The main issue could be the problem of low demand arising out of the GDP contraction in the economy. The problem can be tackled with an extensive marketing campaigning of the company’s products. This would be effective in spreading awareness about the products and making them accessible to the customers. The idea is to develop efficiencies in the operations of the company. It would be crucial to develop economies of scale such through increasing efficiencies in all its work processes. Moreover the high unemployment could be used for the company’ advantage as it would be possible to get labour at low costs and high efficiencies. Labour productivity could be a growing concern for the company seeking to expand in France. This problem would have to be tackled with the use of proper human resource management strategies. HRM theorists have increasingly identified the need for linking HRM strategies with the performance of the workforce. HRM strategies should be such that can attain the maximum contribution from employees and their exploit their maximum potential. The most suitable strategy in this case could be to employ performance based pay in which workers would be paid as per their performance and productivity in the organization over and above their basic pay. Pay linked with performance would be effective in driving up performance standards in the organization through enhanced efficiencies and expertise. The idea is to develop co mpetitive advantage in all activities through increased efficiencies such that costs can be lowered and economies of scale can be attained (Cooke, 2000, p.1-2). However, compensations would have to be backed with rewards structures and training and development programs to ensure maximum involvement of employees in the organization. It is crucial to rewards employees for their good performance in the organization. However, rewards must not always be monetary; employees can be provided with non monetary rewards like words of appreciation, promotions, gifts etc. it can also

The Emancipation Proclomation Essay Example | Topics and Well Written Essays - 2500 words

The Emancipation Proclomation - Essay Example It is relevant to mention that there were no radical steps taken by Lincoln in Emancipation Proclamation. The President followed a well-balanced strategy of the conservatives. He did not want to take radical measures in order not to provoke a strong resonance. Vice versa, Lincoln was very much concerned about the necessity to foster the principles of freedom and the equality of all people, as it is stated in the constitution, but this policy could be implemented only in the case of a well-considerate politics of the President. Thesis statement: anti-slavery moods of Abraham Lincoln, his well-balanced politics, his respect to God, moral and the nation resulted in Emancipation Proclamation and freedom mode of the American society development. Historical Background of Emancipation Proclamation Abraham Lincoln fostered emancipation at the highest speed and no one expected that this process would occur in such a way. The Civil War exerted a great influence on the policy of Lincoln and it shifted the accents of anti-slavery policy of the President. Lincoln is an evident antagonist of slavery, but he is aware of the fact that it is impossible to remove this phenomenon at once, because it takes time and radical instantaneous changes are impossible. Slavery is a deeply-rooted phenomenon of the American society and in order to eradicate it, there is a need to develop innovative reforms and different preventive practices are relevant to halt the development of slavery in America. He was dependent on the environment and the events of the country to the greatest extent that is why it was necessary to develop a properly considered strategy of slavery eradication. Lincoln is often considered as â€Å"an antislavery moderate, a "gradualist," who hoped slavery would slowly die away†1. The striking document of the Kansas-Nebraska Act of 1854 was an alternative for creation of new territories of slavery expansion in America. The political party of Lincoln, Whig Party, expe rienced an inner split because of different attitudes of its members to the issue of slavery. Lincoln commented on his indignation about Nebraska Bill: â€Å"I have always hated slavery, I think as much as any abolitionist. I have been an Old Line Whig. I have always hated it, but I have also been quiet about it until this new era of  introduction of  the Nebraska Bill began†2. Lincoln meant that there is an expansion of slavery, in case different states will join the slave states and the question of the slavery will rise again. Arguments about the Nebraska Bill were intensified, when the Republican Abraham Lincoln opposed to the Democrat Stephen Douglas in 1858. The latter supported the Bill very much and Lincoln opposed to the division of the nation, because no nation would survive in case it is half slave and half free. Lincoln denied his intention to make all the races equal. This fact can be criticized, because Lincoln claimed that in the Declaration of  Independen ce "all men are created equal" and this was a starting point for him to foster his fundamental anti-slavery principles. Lincoln won a great reputation and support of the nation. In 1860 he clearly stated that he opposes to slavery and thus he won the election against a split Democratic Party. In the beginning of his presidency, the Civil War broke out. Lincoln made an attempt to please different states and he persuaded those states, where slavery has already been introduced that he would not eradicate it in those states. He

Climate Change in the boreal forests Research Proposal

Climate Change in the boreal forests - Research Proposal Example Migration rate of trees and plants will be explored through review of the available scientific literature and by studying applicable data as well as geographical maps pertaining to the subject. Scientists have been able to record the travels of boreal forest species in the past by linking the appearance and disappearance of tree with the Earths carbon dioxide level and temperature. These data will be further investigated and analyzed so that migration rates could be accurately established. The paper will also try to explore available models that have been employed to study the migration rate and consistency among the results derived from them. This will help correlate the results derived from the other statistical methods. That is how the true picture of migration rate can be found. Due to migration, boreal forests are likely to reduce at a much faster rate compared to what they can expand. The net effect will be drastic reduction in boreal forest cover releasing considerable amounts of carbon into the atmosphere. That will further speed up the rate of climate change setting a vicious cycle. The rate of migration, thus, will help predict the likely consequences in coming years and help us take remedial measures for the survival of

Organizational Behavior Concepts Of Wal-Mart Essay

Organizational Behavior Concepts Of Wal-Mart - Essay Example This essay states that Wal-Mart transformed the retail industry. It is sheer size, growth and profitability of Wal-Mart that it is in a position to define corporate trends. It is now in a position that it can dictate and perfect the nature of discount stores. Wal-Mart has the image of a friendly, all-American company employing happy workers and smiling greeters who are eager to help and grateful to work at Wal-Mart. As a globalizing force, Wal-Mart exerts influence on the regional, local and national economy. It has restructured the American workforce and consumer behavior. Its basic strategies revolutionized the global retail industry and led Wal-Mart to unprecedented heights. Human resource management is a stronghold of Wal-Mart as right from the inception they did not believe in allowing or forming a union. They felt it was detrimental to the interest of the company and the union only fed itself from both the management and the labors. They believed in exhorting their own people, motivating them through incentives and awards such as company stocks by which they could also make up for the low wages. However, while they claim that the associates are in effect their partners, the high staff turnover and the numerous litigation cases against the company is sufficient evidence of how power is concentrated at the top. Organization culture should serve to strengthen the company and not impact it negatively. In conclusion, Wal-Mart may have a strong culture, but it is most often imposed.

Making Sense of DNA Backlogs. Evidence Backlog Epidemic Research Paper

Making Sense of DNA Backlogs. Evidence Backlog Epidemic - Research Paper Example Apart from the usual fingerprint analysis, the use of DNA evidence is employed in other relatable areas such as footwear evidence, accounting crimes, vein matching, glove-print analysis and body identification, among others. This means that the use of DNA evidence plays a pivotal role in crime scene investigations, analyzing trace evidence and skid marks. Nevertheless, despite the magnanimity that comes with the use of DNA evidence, the backlog epidemic that is constantly accosting it is undermining its usefulness. Several factors underpin the DNA evidence backlog, as shall be seen forthwith. The seriousness of the matter concerning DNA evidence backlog is compounded by the fact that cases are considered backlogged if 90 days elapse without the DNA evidence having been analyzed, or when the DNA evidence has not been subjected to analysis and the final report tabled before the agency that submitted the DNA evidence. Because of this, the DNA backlog can be split into: arrestee; casewor k; and convicted offender DNA backlog. The main cause of the buildup in coursework DNA backlog is the very nature of coursework DNA gathering exercise. Given that forensic evidence is herein gathered from crime scene, suspects and victims of crime before being taken to laboratory, processing this kind of evidence consumes time. This is because the evidence must be screened to establish the presence of biological materials. After the detecting the presence of biological material, the nature of the biological material must then be determined. Subsequently, the DNA testing begins. In the event that further complications are brought about by degrading and fragmenting of the DNA evidence from multiple victims or suspects, then more time will be required to solve the complication, and thereby making the process more protracted (Nelson, 2010). The foregoing is not the case with the arrestee and the convicted offender DNA which is less amenable to backlogs. This is because, in the arrestee and convicted offender DNA, there are identical media such as paper products which help in analyzing samples. At the same time, standardized collection methods are available to facilitate forensic laboratories to subject different samples to automated analysis at one go. Similarly, arrestee and convicted offender DNA evidence can be subjected to robotic platforms to process several score of samples in a 96-sample format. Additionally, unlike the case of casework DNA sample, the laboratory analyst needs not find the DNA sample amidst the evidence obtained. This means that the DNA evidence backlog

Catcher in the Rye Excerpt Essay Example for Free

Catcher in the Rye Excerpt Essay I said Im not going back to school. You can do what you want to do, but Im not going back to chool, she said. So shut up. It was the first time she ever told me to shut up. It sounded terrible. God, it sounded terrible. It sounded worse than swearing. She still wouldnt look at me either, and every time I sort of put my hand on her shoulder or something, she wouldnt let me. Listen, do you want to go for a walk? I asked her. Do you want to take a walk down to the zoo? If I let you not go back to school this afternoon and go for walk, will you cut out this crazy stuff? She wouldnt answer me, so I said it over again. If I let you skip school this afternoon and go for a little walk, will you cut out the crazy stuff? Will you go back to school tomorrow like a good girl? I may and I may not, she said. Then she ran right the hell across the street, without even looking to see if any cars were coming. Shes a madman sometimes. I didnt follow her, though. I knew shed follow me, so I started walking downtown toward the zoo, on the park side of the street, and she started walking downtown on the other goddam side of the street, She wouldnt look over at me at all, but I could tell she was probably watching me out of the corner of her crazy eye to see where I was going and all. Anyway, we kept walking that way all the way to the zoo. The only thing that bothered me was when a double-decker bus came along because then I couldnt see across the street and I couldnt see where the hell she was. But when we got to the zoo, I yelled over to her, Phoebe! Im going in the zoo! Cmon, now! She wouldnt look at me, but I could tell she heard me, and when I started down the steps to the zoo I turned around and saw she was crossing the street and following me and all. There werent too many people in the zoo because it was sort of a lousy day, but there were a few around the sea lions swimming pool and all. I started to go by but old Phoebe stopped and made out she was watching the sea lions getting feda guy was throwing fish at themso I went back. I figured it was a good chance to catch up with her and all. I went up and sort of stood behind her and sort of put my hands on her shoulders, but she bent her knees and slid out from meshe can certainly be very snotty when she wants to. She kept standing there while the sea lions were getting fed and I stood right behind her. I didnt put my hands on her shoulders again or anything because if I had she really wouldve beat it on me. Kids are funny. You have to watch what youre doing. She wouldnt walk right next to me when we left the sea lions, but she didnt walk too far away. She sort of walked on one side of the sidewalk and I walked on the other side. It wasnt too gorgeous, but it was better than having her walk about a mile away from me, like before.

System analysis

System analysis 4.1 Introduction System analysis is a major activity which takes place when we are structure a latest system or changing one. Analysis will help us to understand about the existing system and also will know the requirements necessary for the latest system. And if there is no accessible system then system analysis will defines only the necessity. In system analysis the most important factor is to identify and rectify problems in system. A well understanding of the system will enables designer to understand and rectify the system problems. Existing Software The software is implemented in the system hard disc to the server. The server program runs constantly and waits for a connection to be recognized to it and will make available on line system to automate different operations completed in the network. 2.1.1 Existing System In past the company staff uses the legacy system of carrying interoffice mails by the messengers from one user to other user of the company or they can also use the intercoms for call conference or even in some cases emails are used for transmit of messages between the group community There are some disadvantages in existing system * Tedious message broadcasting system. * Communication is not instant. * Message transfer is done through insecure communication media. * Communication delays. * Maintaining the identities of all the members is not efficient. Like using manual books, diaries, etc., for storing of users information. 2.1.2 Proposed System To overcome the shortcomings of the conventional systems, the project aims at developing a multithreaded public messaging system for broadcasting messages to every member in the channel; that allows multiple people (users) to interact with each other in a shared environment. The proposed system aims to fulfill the following: Ã ¾ Sharing of data in a real time environment, i.e., the data broadcasted can be edited online and viewed simultaneously. Ã ¾ Providing fast, secure, reliable and cost effective broadcasting communication medium between community members. Ã ¾ Support for public and private channels of communication. Ã ¾ Multiple media transmission support; like voice, text, images, etc. Ã ¾ Personal peer messaging service. Ã ¾ A user-friendly interface 2.2 Requirement Analysis Requirement analysis provides software designer with a model of: Ø System information Ø Function Ø Behaviour Model can be translated to data, architectural, and component-level designs. 2.2.1 Analysis Objectives Ø Identification of the customers needs. Ø Evaluation of the system for feasibility. Ø Perform technical analysis. Ø Establish constraints. Ø Create system definitions 2.3 Software Requirements Analysis Phases Problem recognition: The existing system provides the information about products in the form of Local Advertisements media and paper advertisements. This is not sufficient to reach the end user properly. So, the company management is willing to maintain a web site which one accomplished all firm in detailed. Evaluation and synthesis: After getting the clear problem definition we focused on what to do but not how to do. Ways to solve the problem and among the different ways we found and we selected the best way to solve the problem. Modeling: We made a rough diagram of the proposed system and showed it to the clients to verify whether their specifications are completely mentioned in that or not. Specifications: The software and hardware requirements and complete specifications are known. The functional and non functional requirements are known. Constraint: The constraints are known and a clear definition of the system is given. Review: A review of the whole process what we did and the result are shown to the clients. 2.4. Feasibility Study Feasibility study is conducted once the problem is clearly understood. It is a high level capsule version of the entire System Analysis and Design process. The main objective is to determine how to solve a problem quickly, at a minimum expense and to check if the problem is worth solving. This system has been tested for feasibility in the following points: Ø Operational Feasibility Ø Technical Feasibility Ø Economical Feasibility 2.4.1 Economic Feasibility Economic feasibility is the most frequently used method for evaluating the effectiveness of the proposed system. During study costs are considered like costs of hardware, minimum configuration, system compatibility of H/W, etc., the proposed system minimizes the time effort of the data collection, answering queries and generating reports which results in significant saving. Thus, the proposed system is economically feasible. 2.4.2 Operational Feasibility Proposed projects are beneficial only if they can be turned into information systems that will meet the requirements. As current business methods are not acceptable to the users in terms of speed, timely and accurate results, users welcomed a change that will bring about a more operational and useful system. With the rarely involvement it reduced the chances of resistance to the system and change in general and increased the likelihood of the project successfully. 2.4.3 Technical Feasibility It centers on the existing computer system and to what extent it can support the proposed system. The system can be expanded as the need arises. With the obtained technology there is guaranteed of accuracy, reliability, ease of access and security. Thus, it is technically feasible to design and develop the proposed system. 3.

Number system is used in IT applications

Number system is used in IT applications In this documentation I have discussed of how the application of number system is used in IT applications in both hardware and applications, operating system and in programming language. I have discussed about the use of base 2 in the 8 bit bytes form use with the operation for subnet. The use of hexadecimal form addressing memory and classless inter Domain Routing. There are number of different numbering system which is in use for the unique ability to represent different numbers. Binary, Octal, Denary and Hexadecimal are number systems that are used in different aspects Denary number is the most commonly used number system which is frequently used in daily life. Nevertheless each number system has associated benefits which are the reason that different number systems are used in different areas. Each of the number system has a fix number of representation of numbers which are used to represent the numbers like, say for example Binary numbers are represented by either one or zero, Octal numbers are represented by numbers from 0, 1, 2, 3, 4, 5, 6, 7 whereas Denary and Hexadecimal numbers are represented by the number of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0, 1,2. 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, respectively. Binary Numbers Binary numbers are mostly used when there are only two options available so if one is false then the other is true. Examples of binary system can be their usage to represent bits in a computer which can have only 0 or 1 value a switch in a electric circuit which can be either on (1) or off (0). Binary system is widely used to represent situations in everyday normal life as well for example for electronic gates in electricity circuits, false or true statements can also be displaced in terms of binary digits where 0 represents false and 1 represents true states. Denary Numbers Denary numbers are frequently used in everyday life in accounting, calendar systems, financial systems or daily routine counting. The main benefits of Denary number system is that they are easier to use as compared to other number systems and have more number to present different situations though Hexadecimal number system has more representations but that representation can include characters in them as well which makes them more difficult to understand and use as compare to denary system. Denary number systems are so frequently used that a person even do not need to have a formal education to know or use them. One of the reasons can be that it is frequently use in daily life accounting. Other number systems are used in more specified fields such as computing and hence would need to be learned. Octal Numbers Octal numbers are not that commonly used as compared to other numbers and are mostly used in computing graphics, text and famous operating system such as UNIX also uses octal numbers for their file protection system. Octal numbers have total of 8 unique representations which can be combined together to make more octal number representations. Octal numbers are difficult to understand for a normal person who has limited number of understanding about the number system. As after 7 different numbers are used to represent numbers from 7 onwards and hence they seem physically bit difficult to comprehend. The number system needs to use a subscript of 8 with is number to represented they are not Denary but octal number otherwise confusion can easily occurred. Hexadecimal Number System Hexadecimal number are used where there are more options which needs to be represented off and are mostly commonly used in computing to represent different memory locations. Since binary, octal and hexadecimal have representations which are powers of 2 (power of 0 in binary, 3 in octal and 4 in hexadecimal) hence that makes them more suitable to different situations, which require different number representations. They are positively contributing to the daily life and to the technology and logical world as well and needs to be understood properly if one needs to take advantage of such technology. Whilst the above gives uses of the binary, octal and hex number systems in different areas of IT and while some example are given the manager encourages you to research a wide range of examples for him to look at. Binary Number System used in ASCII table and IP Address   Binary number system are also used in the ASCII table to represent different codes for different characters which then can be used into computing as well. ASCII number is more like a combination of binary numbers. Binary numbers are also used in IP addressing system again which is a combination of Binary number and are used in computing field. These IP addresses are of two different versions now one is known as IP 4 and other one is known as IP 6. These IP addresses are further sub divided into different classes such as class A, B and C where each class has a different number of hosts and network address. The ASCII character set, each binary value between 0 and 127 is given a specific character. Most computers extend the ASCII characters set to use the full range of 256 characters available in a byte. The upper 128 characters handle special things like accented characters from common foreign languages. In ASCII character set, each character is represented by 7 bits when stored in the computer and in an extended ASCII character set, each character is represented by 8 bits. Say for example: ASCII 0000000 represents NULL Similar the word ‘HELLO if converted into binary using the ASCII to binary conversation could be represented as follows. 01001000 01000101 01001100 01001100 01001111(in decimal   72 69 76 79) Please refer an ASCII character table for further understanding of this conversion. Octal numbering system for file protection in UNIX Every file or folder in UNIX has access permission. There are three types of permissions (what allowed to do with a file): Read Access Write Access Execute Access Permissions are defined for three types of users: The owner of the file The group that the owner belongs to Other users Thus, UNIX file permission are nine bits of information (3 types x 3 type of users), each of them may have just one of two values: allowed or denied. Simply put, for each file it can be specified who can read or write from/to the file. For programs or scripts it also can be set if they are allowed to be executed. Textual representation like â€Å"-rwxr-r-â€Å" It is used in UNIX long directory listings. It consists of 10 characters. The first character shows the file type. Next 9 characters are permissions, consisting of three groups: owner, groups, others. Each group consists of three symbols: rwx (in this order), if some permission is denied, then a dash â€Å"-â€Å"is used instead. For example -rrwxrr- 0123456789 Symbol in the position 0 (â€Å"-â€Å") is the type of the file. It is either â€Å"d† if the item is a directory or †l† if it is a link, or - if the item is a regular file. Symbols in positions 1 to 3 (rwx) are permissions for the owner of the file. Symbols in positions 4 to 6 (r) are permissions for the group. Symbols in positions 7 to 9 (r) are permissions for others. r Read access is allowed w Write access is allowed x Execute access is allowed Replaces r, w or x if according access type is denied Numeric (octal) representation like â€Å"664† If a numeric representation is used (like in chmod-command, for example), then it is in the octal format (with the base of 8), and digits involved are 0 to 7. Octal format is used for the simplicity of understanding: every octal digit combines read, write and execute permissions together. Respective access rights for owner group and others (in this order) are the last three digits of the numeric file permissions representation. Example: â€Å"0644†. Here the second digit (â€Å"6† in the example) stands for rights of the owner, the third digit (â€Å"4† in the example) stands for rights of the group, the fourth digit (â€Å"4† in the example) stands for rights of others. The below tales show what numeric values mean: Octal digit Text equivalent Binary value Meaning 0 000 All types of access are denied 1 x 001 Execute access is allowed only 2 -w- 010 Write access is allowed only 3 -wx 011 Write and execute access are allowed 4 r 100 Read access is allowed only 5 r-x 101 Read and execute access are allowed 6 rw- 110 Read and write access are allowed 7 rwx 111 Everything is allowed According to the above table we can see that â€Å"1† stands for execute only, â€Å"2† stands for write only, â€Å"4†stands for read only. To combine the permission you can simply add 1, 2 and 4 to get a needed combination. For instance, to get read and write permission, you add 4 (read) and 2 (write), thus getting 6 (read and write). To get read and execute permissions, you add 4 (read) and 1 (execute), this getting 5 (read and execute). Example: 755 on a file would mean rwx r-x r-w permission on the file. Simply convert the octal number to the binary equivalent and enable the permission where the bits are 1. 755 would mean 111 101 101 In addition there is one more octet representing the Set user ID, set group ID, sticky bit which works in a similar way. Octal digit Binary value Meaning 0 000 setuid, setgid, sticky bits are cleared 1 001 sticky bit is set 2 010 setgid bit is set 3 011 setgid and sticky bits are set 4 100 setuid bit is set 5 101 setuid and sticky bits are set 6 110 setuid and setgid bits are set 7 111 setuid, setgid, sticky bits are set Explain the use of binary in IP addressing for both V4 and V6? Use of binary in IP addressing for V4: Each IP in a V4 IP addressing consists of 32 bits. These 32 bits are divided into 4 octets of 8 bits each. An IP address is represented like this: 172.12.12.46. A computer can understand only binary values and therefore each IP is stored in binary. Each octet is represented as follows. For example if the value of the first octet is 128, it would be represented as follows: 128 64 32 16 8 4 2 1 1 0 0 0 0 0 0 0 Therefore an IP 128.128.128.128 would be stored as follows: 10000000 10000000 10000000 10000000 Use of binary in IP addressing for V6: While IPv4 allows 32 bits for an Internet Protocol address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128(3.4 x 1038) addresses. This expansion allows for many more devices and user on the internet as well as extra flexibility in allocating addresses and efficiency for routing traffic. The IPv6 128-bit address is divided along 16-bit boundaries. Each 16-but block is then converted to a 4-digit hexadecimal number, separated by colons. The resulting representation is called colon-hexadecimal. This is in contrast to the 32-bit IPv4 address represented in dotted-decimal format, divided along 8-bit boundaries, and then converted to its decimal equivalent, separated by periods. The following example shows a 128-bit IPv6 address in binary form: 0010000111011010000000001101001100000000000000000010111100111011 0000001010101010000000001111111111111110001010001001110001011010 The following example shows this same address divided along 16-bit boundaries: 0010000111011010  Ã‚   0000000011010011  Ã‚   0000000000000000  Ã‚   00101111001110110000001010101010  Ã‚   0000000011111111  Ã‚   1111111000101000  Ã‚   1001110001011010 The following example shows each 16-bit block in the address converted to hexadecimal and delimited with colons. 21DA:00D3:0000:2F3B:02AA:00FF:FE28:9C5A IPv6 representation can be further simplified by removing the leading zeros within each 16-bit block. However, each block must have at least a single digit. The following example shows the address without the leading zeros: Javascript:CodeSnippet_CopyCode(‘CodeSnippetContainerCode3); 21DA:D3:0:2F3B:2AA:FF:FE28:9C5A Binary in describing class A, B and C IP addresses The class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number. Class A Network binary address start with 0, therefore the decimal number can be anywhere from 1 to 126. The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. An example of a Class A IP address is 102.168.212.226, where 102 identifies the network and 168.212.226 identifies the host on that network. Class B Network binary addresses start with 10, therefore the decimal number can be anywhere from 128 to 191. (The number 127 is reserved for loopback and is used for internal testing on the local machine.) The first 16 bits (the first two octets) identify the network and the remaining 16 bits indicate the host within the network. An example of a Class B IP address is 168.212.226.204 where 168.212 identifies the network and 226.204 identifies the host on that network. Class C Network binary addresses start with 110, therefore the decimal number can be anywhere from 192 to 223. The first 24 bits (the first three octets) identify the network and the remaining 8 bits indicate the host within the network. An example of a Class C IP address is 200.168.212.226 where 200.168.212 identifies the network and 226 identifies the host on that network. Hexadecimal for addressing memory Memory addresses are displayed as two hex numbers. An example is C800:5.   The part to the left of the colon (C800) is called the segment address, and the part to the right of the colon (5) is called the offset. The offset value can have as many as four hex digits. The actual memory address is calculated by adding a zero to the right of the segment address and adding the offset value, like this: C800:5 = C8000 + 5 = C8005 C8005   is called as the absolute or linear address of the memory. Similarly F000:FFFD can be computed to get the following memory address. F0000 + FFFD FFFFD   or   1,048,573(decimal) The Segment: Offset addressing was introduced at a time when the largest register in a CPU was only 16-bitslong which meant it could address only 65,536 bytes (64 KB) of memory, directly. But everyone was hungry for a way to run much larger programs! Rather than create a CPU with larger register sizes (as some CPU manufacturers had done), the designers at Intel decided to keep the 16-bit registers for their new 8086 CPU and added a different way to access more memory: They expanded the instruction set, so programs could tell the CPU to grouptwo 16-bit registers together whenever they needed to refer to an Absolute memory location beyond 64 KB. Classless Inter Domain Routing Classless Inter Domain Routing. CIDR was invented several years ago to keep the internet from running out of IP addresses. The classful system of allocating IP addresses is very wasteful. Anyone who could reasonably show a need for more that 254 host addresses was given a Class B address block of 65533 host addresses. Even more wasteful were companies and organisations that were allocated Class A address blocks, which contain over 16 Million host addresses! Only a tiny percentage of the allocated Class A and Class B address space has ever been actually assigned to a host computer on the Internet. CIDR specifies an IP address range using a combination of an IP address and its associated network mask. CIDR notation uses the following format xxx.xxx.xxx.xxx/n where n is the number of (leftmost) 1 bits in the mask. For example, 192.168.12.0/23 applies the network mask 255.255.254.0 to the 192.168 network, starting at 192.168.12.0. This notation represents the address range 192.168.12.0 192.168.13.255. Compared to traditional class-based networking, 192.168.12.0/23 represents an aggregation of the two Class C subnets 192.168.12.0 and 192.168.13.0 each having a subnet mask of 255.255.255.0. In other words, 192.168.12.0/23 = 192.168.12.0/24 + 192.168.13.0/24

Donne’s Poem Death Be Not Proud :: Death Be Not Proud Essays

Donne’s Poem Death Be Not Proud In the poem "Death Be Not Proud," written by John Donne death is personified. The personification of death creates a feeling that death is less powerful than we think. Donne creates and image of death that is not mysterious, not in control, and a slave of low status. He does this by undermining the idea of death as bound to the rules of "fate, chance, kings, and desperate men." He insists that death is no more powerful than any mortal is. Suggesting that death is not mysterious is the word slave. Directed to death, "thou art slave" forms an unthreatening stance of death because slaves are not threatening. This is due to the connections that go with the word slave. A slave is bound in submission to a master therefore having no say in what he or she can do. Death, in being personified into a slave that has many masters, is more extremely bound. This lack of freedom that death has in choosing its victims takes away any reason to be fearful of it. Power comes from being able to control something. Here death is the one being controlled by other outside forces that have power over how and when death can do its work. Death casts fear into mortals because it is unknown as to what happens in the afterworld. This poem creates a sense that we know who death is. For example we can see how death is a poor beggar on the street. This would make death a non-threatening person. He is a low class citizen that is just waiting for an opportunity to feast when his master allows. Donne produces this low-life death figure by associating him with "poison, war, and sickness." These are all things that less fortunate mortals deal with on a daily basis. These are dreadful things that are not good. Death personified is subject to these horrible circumstances therefore is very low in stature. If death can only reap his vengeance with such low standards governing him, then death is as low as what he works for. Death becomes less mysterious and something which we are not afraid of.

The wars affect on civilization :: essays research papers

This paper is about stuff i know little about. I'm eally just riting this so i can get some stuff for myself. I plan on making contributions to this site at a later time. As for now, I will just type this so as to gain access to the site. As you hav noticed I put one space after each end of sentence period, although most common typing books tell you to use two. That is a bunch of hooey. Well I don't know how many words I have but I need my report stat cuz it's due tomorrow. So, with no further ado, I end my fake essay by saying, goodbye. What is wrong with this paper? Didn't I put enough words in it? It seems like culture and society are words I can use to make my registration complete. It may be that it is too short. Or I might not be using words like exploration or journalism. Some other things it could be are they know this entire report is not real. So therefore, two out of three is not bad. Therefore I will make this long as possible. Apparently you are not truly married. Whoa! I say. This paper has to be 250 words or more. I don't understand it. This is the third time I tried sending it and to my surprise it's not long enough. What more can I do? It's tough writing essays like this man.The communications links of the Internet are also owned and maintained in the same anarchic fashion as the hosts. Each owner of an Internet host is responsible for finding and paying for a communications link that will get that host tied in with at least one other host. Communications links may be as simple as a phone line, a wireless data link such as cellular digital packet data, or as complicated as a high speed fiber optic link. As long as the communications link can use TCP/IP or UUCP, it can fit into the Internet. Thus the net grows with no overall coordination. A new owner of an Internet host need only get permission to tie into one communications link to one other host. Alternatively, if the provider of the communications link decides this host is, for example, a haven for spammers, it can cut this â€Å"rogue site† off of the Internet. The rogue site then must snooker some other communications link into tying it into the Internet again.

Judicial Precedent Is Best Understood as a Practice

Judicial precedent means the process whereby judges follow previously decided cases where the fact are of sufficient similarity. The doctrine of judicial precedent is a practice of the court, it provides guidance to the judges when they apply case precedents. It also provides certainty, consistency and clarity in the application of precedents. The rule is that judges should decide like cases in like manner. It is a decision of the court used as a source for future decision making. This is known as stare decisis and by which precedents are authoritative and binding and must be followed. Doctrine of precedent or stare decisis, this item is from the latin phrase â€Å"stare decisis et non quieta movere†, means to stand by decisions and not disturb that which is settled. The doctrine of binding precedent based on stare decisis, that is standing by previous decisions. Once a point of law has been decided in a particular case, that law must applied in all future cases containing the same material facts. For example in the case of Donughue v Stevenson (1932) AC 562. The House of Lords held that a manufacturer owed a duty of care to the ultimate consumer of the product. This set a binding precedent which was followed in Grant v Knitting Mills (1936) AC 85. The ratio decidendi forms the legal principle which is a binding precedent meaning it must be followed in future case containing the same material facts. Besides, the obiter dicta is things stated in the course of a judgment which are not necessary for the decision. The decision of the judge may fall into two parts, the ratio decidendi means reason for the decision. The ratio decidendi in a case is the principle of law on which a decision is based. When a judge delivers judgment in a case he outlines the facts which he finds have been proved on the evidence. Then he applies the law to those facts and arrives at a decision, for which he gives the reason. Besides, obiter dictum means something said by the way. The judge may go on to speculate about what his decision would or might have been if the facts of the case had been different. The binding part of a judicial decision is the ratio decidendi. An obiter dictum is not binding in later cases because it was not strictly relevant to the matter in the original case. However, an obiter dictum may be of persuasive authority in later cases. For example, in the case Donoghue v Stevenson (1932), the house of lords held that a manufacturer owed a duty of care to the consumer that products are safe because the circumstances prevented the consumer from discovering any defects. This is a ration decidendi and lord Atkin’s â€Å"neighbour test† was obiter. Where there is no existing precedent, the court will declare the law and the case will become an original precedent, example, in the case Airedale NHS Trust v Bland (1993) HL, where the courts were asked to decide if food and treatment could be lawfully withdrawn from a patient in a persistent vegetative state, and thus allowed to die. The concept of ratio decidendi tries to link the competing aims of the notion of rule of law, ie, the requirement of certainty in the application of law and flexibility in the development of law within the legal system. To identify the ratio in a case, Professor Goodhart (1931), set out a method of identifying the ratio decidendi as the ratio is derived from the application of the law to the facts that were treated as material by the judge in his decision and generalising them to make a principle. Besides that the principle of the case is found by taking account of the facts treated by the judge as material ; and his or her decision as based on them. The principle is therefore a formula, which the facts fit, and the facts provide a specific instance or example of the application of the principle. However, Professor Julius Stone (1959) argued that Goodhart’s theory was prescriptive rather than being descriptive of actual practice. In Stone’s analysis, the ratio of a case is part of a legal category of indeterminate reference or concealed multiple reference. The facts of a case precedent are able to be material under a wide range of fact descriptions, but any given decision was open to a succession of subsequent judicial reformulations of the prior decision. So, the question for the later court is the analogical relevance of the prior case holding to the later case, thus requiring the later court to choose between possibilities presented by the earlier case. This gives us a picture of radical indeterminacy . This is because the later courts appear to have great freedom in reinterpreting the actual ratio of the certain case. Stone’s approach is considered as a rather radical scepticism towards the concept of ratio. Consequence of the indeterminacy of the ratio is the difficulty in identifying the ratio of a case actually provides the English common law system the flexibility when case law is applied and its subsequent development through the courts. From Cross (1991) who argues â€Å"it is impossible to devise formulate for determining the ratio decidendi of a case†, but ‘this does not mean it is impossible to give a tolerably accurate description of what lawyers mean when they use the expression’. Consequently, courts have a great deal of choice in reformulating and interpreting law. In his work on legal reasoning , Neil MacCormick (1987) makes the point that often the ratio of a case can only be determined in light of what judges subsequently make of it. In conclusion, the discussion above have gone to establish that the doctrine of binding precedent is nothing more than a practice of the English judiciary. As a judicial practice, the doctrine provides a guide to judges on how case precedents are to be applied in courts. If the doctrine is avoided or not allowed, there are no legal sanctions or consequences. At worst, if there is a rampart ignoring of the doctrine by the courts, the outcome will be uncertainty and instability in the common law and its development.

Effects of Globalization in China Essay

When it comes to globalization people will ask some questions. What is globalization? It seems that people who know little about globalization are out of date and lag far behind modern trends. Simon Jeffery (2002) asserts that globalization is the mixing of cultural and economic influences from around the world that has been going on for the last five hundred years. With the development of the global market in China, globalization plays an important role that is undeniably because China has the fastest growing economy in the world. Globalization provides good conditions for expanding international exchanges and strengthening mutual communication between different countries. Although there are many facets to globalization, the increasing acceptance of this concept has resulted in a certain homogenization of views, both economic and political as well as in cultural systems, but most noticeably in economics. (Diane Perrons 2004) The most obvious impact of globalization is as an economic phenomenon, the promotion of free trade in goods, both exports and imports, accompanied by the exchange of labour and services. China has a long history of trade, from the Han Dynasty onwards the Silk Road was the artery of communication which extended across continents as far as Rome itself, then the capital of a world empire. However, throughout the Ming and Qing dynasties China pursued a policy of economic protectionism, leading to a long period of isolation that was brought to an abrupt end with the Opium Wars. The resulting economic degradation enforced by the victorious British had such disastrous consequences for modern China that it was not until the advent of Deng Xiaoping and his reform and opening up policy that China’s development was accepted as inseparable from the outside world. (George T Crane 1999) In recent years the extent to which globalization has been gaining in popularity has increased at an amazing rate in China. The benefits of modern economic globalization since opening up are indisputably reflected in the nation’s booming economy so that China can only be considered undeveloped in comparison to the most developed nations. However, globalization does not always pose equal benefits and risks to all nations. With the developing of the economy in China, the inequality between developing countries and developed countries has been increasing and the gaps between the very poor and the very rich are becoming wider. China has an overwhelming advantage compared with most of the developing countries in terms of finance and the level of technology, culture and science but it is still the superpower countries and other developed capitalist countries which control the main situation of economic globalization in the world. Many people believe that opportunists, both individually and nationally, use globalization purely as a means to increase their profits at China’s expense. The advent of globalization in its present form would not have been possible without adaptations in national politics. Some view globalization as the means to create a form of world government or a union of governments, for example within the World Trade Organization, the World Bank and the International Monetary Fund, which helps to regulate the relationships between different countries and provide guarantees for the rights of peoples affected by the increase of economic and social globalization. (Francesco Stipo 2007) Recently, it has become more noticeable how the Chinese political authorities regularly cite the advances in ‘socialist construction’ and the vitality of new economic growth as an indication of national success. The association with other powers has encouraged the Chinese government to open up in all directions, by lowering tariffs, opening services to foreign competition, promoting exports and welcoming foreign trade the government has allowed a free exchange of ideas in all directions and helped China to become a more prosperous, strong, democratic and culturally advanced socialist country. Unfortunately, these benefits may carry a hidden danger. Since the end of the Second World War the United States has held an overall position of supremacy amongst the other nations of the world, a position which is enhanced by the power and wealth of the American economy. Due to the influence of globalization and to some extent the assistance of the United States’ itself, the People’s Republic of China has enjoyed a period of incredible growth within the last ten years. Should this rate of growth continue at the predicted levels over the next twenty years, there is a strong possibility of a major redistribution of influence among the leading nations. China could become the main rival of the United States and challenge America’s position as the world’s leading superpower. (Charles E Hurst 2007) It will take great political skill from fundamentally opposed ideologies to avoid serious resentment and possible conflict as a consequence of such a drastic shift in the balance of power. Alongside the other developments in globalization, there has been an increasing change to the original culture of China. According to David Held & Anthony McGrew (2002), national societies developed during a long period in which people were mainly content to live within their own native cultures. Although the spread of the world’s major religions can be seen as an early form of globalization, which brought new ideas and made many social impacts, this was a relatively slow process taking decades and centuries in China. People migrating from other countries and holding different beliefs naturally find it difficult to adapt to local customs but China has a long history of absorbing whole populations with diverse ethnic backgrounds. As a result of the economic and political benefits brought by globalization, people have increased their standard of living and enjoy foreign products and ideas. Modern developments in communication are widely available even in the remotest regions and many people want to acquire the equivalent of a westernized urban lifestyle. On the other hand, those who are against this trend suggest that modern globalization creates an atmosphere where there is a possible danger of the original national culture disappearing and that it exerts a negative impact on the preservation of national characteristics. While globalization advocates an open face policy, many people see this as a threat leading to erroneous concepts and a lowering of ethical standards, a kind of selfish and individualistic lifestyle which is harmful. For example, the preference for Hollywood films, shoppers buying from international malls, more people eating western food and staying in luxury hotels. Increasingly, people want the chance to live in foreign countries where they can have this lifestyle but the resulting ‘brain drain’ is considered a problem since it is mainly the educated and skilled workers who are leaving China. Gregory Chow 2006) Globalization is changing an increasing number of people’s daily life in China and it is difficult to predict the eventual cost in cultural damage to such a traditional people. To sum up, from what has been discussed about globalization, how does this affect China and her position in the world? Globalization could be identified as the means to end any con flict between different interests because different groups of people hold different views, ideologies, perspectives and methodologies. Globalization might have the impetuous to resolve the complicated competition between China and other countries. However, China should take some measures to protect both the national and local culture and consider adjusting the economic pace in the rush to catch up with other countries. As to the result, it might be very difficult to safeguard against the worst aspects of globalization and to preserve China and maintain that unique heritage which is such a feature in the world.

Socioeconomic Structures and History in Spanish and Portuguese

Heather Coffey HIST 3401W December 18th, 2012 Socioeconomic Structures and History in Spanish and Portuguese America from the Conquest until Post Colonial Period Throughout the entire history of Portuguese and Spanish occupation of the Americas there were evolving hierarchies, labor regimes, gender relations, sources of wealth, regions of wealth, trade routes, uprisings, economic hard times and high times, etc. A very prominent source behind this constant ebb and flow of the history of Portuguese and Spanish Americas can easily be attributed to the economic forces always at play.It can be seen in the reasons for the conquest of Latin america and South America, the onset of the colonial period and the rebellions of eighteenth century. It is important to understand the economic drives that were in play in the beginning of the conquest because it would inevitably change the social landscape of Mexico, the outlying islands and South America forever. The Age of Exploration brought upon a wealth of knowledge for the world, and specifically for the Kingdoms of Spain and Portugal it also brought a lot of wealth.The rivalry between the two kingdoms and need for financial gains led the two to divide the areas of the world where exploration was viable with the Treaty of Tordesillas in 1494 which divided the lands East of the demarcation line (halfway between the Cape Verde Islands) to Portugal and the lands west of that to Spain. Keeping within these boundaries, explorers such as Christopher Columbus, Hernan Cortes and Francisco Pizarro (among many others) scoured the newly discovered Americas in search of new land, but also new sources of wealth.Upon reaching the Americas, both in Mexico and the surrounding areas as well as South America, one of the main goals was the search for wealth in Gold and Silver. The hunt for both as well as other rich resources at first led the explorers on a wild goose chase around the alien lands and native people until areas were found and d eemed suitable for settlement and a worthy and financially sound decision as it would prove to be for Spain and Portugal. †¦where have men seen what they see today, fleets entering loaded with gold and silver as if it were iron? Or where was it known or read that so much wealth could come from one kingdom? So much and so great is it that Spain is full of these treasures, and her cities are populated by many rich perusers who have left there. â€Å"1 Once regions were settled and indigenous resistance to colonizing efforts were temporarily brought somewhat under control the exploitation of the rich resources of the land began.There were shiploads of Spanish and Portuguese men (and some women) brought into Latin America to aid in the settlement process, but it was the indigenous that were used in the farming and mining of these resources as well as the upkeep of the households of the white families by the indigenous women. This aided in the creation of the pyramid of the divisio ns of class and caste throughout all of Mexico and South America, at first drawing distinct lines between â€Å"White† and Indian. As time progresses the indigenous succumb to diseases brought by the white people and the population of Indians from all regions declines drastically.African slave trade was key here as they replaced the vast numbers of Indians lost, but also then entered them into the socio-economic orders. In the times of the conquest and the beginnings of the colonial period the lines of race were much clearer, White, Indian and Black, but this would change and the lines would blur through out the colonial period as races mix. The gender relations between the races began early with, more commonly, the slave women or african or Indian descent brought in to do slave work in white households or to do the â€Å"female† tasks of spinning wool, etc. , women were taken in as concubines and thus the blending of white and indian and black began. By the colonial p eriod and beyond there would be upwards of sixteen different names for the gradations in color and subsequently class. The very bottom of the â€Å"social† pyramid being slaves, mostly blacks who were immovable in the caste system due to their â€Å"involuntary citizenship and thus assumed treachery†3. It's interesting to see how the need for free and cheap labor brought what would shape the future identities that would become those of the Americas.Over time the economies of both Spain and portugal became dependent on the goods, tax revenues and tributes coming from Latin America and through times when the â€Å"goods† weren't doing so well they had to rely more heavily on other aspects. There were periods of time when the silver production at Potosi, for instance, wasn't doing well due to lack of supplies needed for mining. These regions then would be hit heavily with raised tributes from lower social orders as well as enforced and raised taxes on goods traded within the regions as would be the cause of the Repartimiento de Comercio in 1751.These financial strains as well as the enforced labor of men used as tribute as well (mita) left the majority of the population (lower classes) financially and even physically weak. This continued to grow and grow throughout the colonial period caused great discontent â€Å"Conflicts over land distribution, tribute rates, mitt allocations, the succession to ethnic leadership posts, and abuses by local priests and corregidores frequently disturbed local indigenous communities during the eighteenth century. The spread of the repartee often exacerbated such local tensions, leading to an escalation of violence. 4 These issues would like to the uprisings and rebellions that would create chaos for the Spanish and Portuguese throughout the late eighteenth century and on, the most notable being those lead by Tomas Katari, Tupac Amaru II and Tupac Katari in Peru and upper Peru from 1780-1783. The socioeconomic history of Spanish and Portuguese America is a broad topic, hard to even begin to explain in a short paper as this. That being said, I believe that it's important to understand the impact that it had on the entire region.The effects that it had on the populations from the declining population of indigenous from illness brought from Europe, to the subsequent new races of people caused by the blending of populations all forced to live together. Also the strain that this would inevitably put on those being taken advantage of by the colonial leaders and Castilian and Portuguese crowns. This entire history from the fifteenth century until the early nineteenth century was put into motion by cause and effect situations led by the greed of men, this need for wealth that would take over and hange the lives of millions. 1.

Trade Dispute between China and the U.S Research Proposal

Trade Dispute between China and the U.S - Research Proposal Example According to Morrison, the U.S. has employed protection of its energy manufacturing firms so that they can spearhead the production of energy (15). This has been executed by the use of subsidies to all firms producing energy in the country. For instance, U.S. President Obama favors the initiation of tax treatment for wind power and solar power as well as an increase in the expenditure of the federal government on the energy sources. The U.S. government has also set aside $50 billion as loans to firms producing nuclear power.  According to Morrison, the U.S. has employed protection of its energy manufacturing firms so that they can spearhead the production of energy (15). This has been executed by the use of subsidies to all firms producing energy in the country. For instance, U.S. President Obama favors the initiation of tax treatment for wind power and solar power as well as an increase in the expenditure of the federal government on the energy sources. The U.S. government has als o set aside $50 billion as loans to firms producing nuclear power.  The U.S. president also seeks to increase the electricity produced from cleaner sources twice by 2035. Such a policy would manipulate the energy markets. Therefore, the U.S. has clear cut goals regarding an increase of clean energy while letting utilities achieve them.  On its part, China has also undertaken various measures toward the manufacture of clean energy. China’s rapid economic growth was fueled by the decision made by the leadership of the country to embrace a capitalist approach to the growth of the economy. This leadership also adapted economic policies that opened up China to foreign investments and implemented free-market reforms in 1979 thereby making it a major global economic and trade power (Morrison 1). Despite its growth, China enforced methods and policies on its people to bolster and maintain the economic growth bordered on dictatorship. Changes in policy and property ownership right s made the Chinese people lose their properties and investments. Economic reforms made much Chinese change their jobs and habitual lifestyles. Redistribution of land to poor peasants and prioritization of agriculture stabilized the agricultural production making it possible for the country to feed its whole population (Thomas 23). The Chinese government owns and controls major industrial and economic sectors in areas such as transport, communication, energy and financial services (Thomas 26). The government regulates the economy by gearing its reforms towards higher productivity, better living standards and exemplary technological quality without aggravating joblessness or inflation.  

A Comprehensive Analysis Of Nike Company Case Study

A Comprehensive Analysis Of Nike Company - Case Study Example The company has invested a lot of resources in research and development, making the largest company in the category of sportswear. With the innovations, the company wants to be identified as the most recognized company in terms of differentiation. Nike has been faced with a series of problems, which has negatively affected the company’s business image, and consequently, its performance. Some claims include the violation of child labor laws and poor working conditions, such as low wages, long overtime hours without guaranteed payment, forced overtime work, no consultation with workers on matters that concern them, poor medical services and others.Nike Vietnam can take some steps to improve its working conditions in order to redeem its tainted image. The dynamism of strategic management is a continuous management. According to David, a change in any of the management component of a company can necessitate a complete change of the company progress. Nike can also find strategies t o hold onto Emerging Markets such as China and India. Considering that its competitors such Adidas, whose market share surges every day. The company can partner with the existing market leaders in these countries to gain entry into the new markets. The youths in the emerging markets should be targeted as they comprise the majority population. In order to redeem its image, the company needs to rebrand a section of its apparel to go in line with the modern management strategy where the ethics/ social responsibility form part of their themes.... Corporate social responsibility forms part of long term strategic management for any large company like Nike. Working Conditions at Nike Vietnam Company- Weakness Nike Inc. is the leading supplier of athletic shoes and equipment, as well as a key producer of sports equipment in the world (Marina 2008). The company is based in the United States, and its head office is in Beaverton, Oregon. Most people are familiar with various products offered at Nike stores, such as Nike Football, Nike Sportswear, and Nike Volleyball etc. It was from the sale of these products coupled with the company’s slogan â€Å"Just Do It† that Nike could get a profit of $15 billion in 2006 (Marina 2008). As of 2008, the company’s revenue was over $18.6 billion, an indication of its business success. It also has an excess of 30,000 workers globally. However, over the past few years, Nike has been faced with a series of problems, which have negatively affected the company’s business im age, and consequently, its performance. Some issues of concern include paying low wages to its workers, and using child labour among others. As expected, such grave claims are bound to affect the successful establishment of any business both locally and internationally, and Nike is not an exception. For instance, Nike’s sweatshop labour case resulted in numerous controversial debates concerning its ethical business practices. That painted a bad image of the company in the public eye. It is what Nike has been still struggling to overcome among American and other customers worldwide, even if it has tried to recover from bad press coverage. Literature Analysis Over the past few years, Nike has been faced

Key Concepts in Management Coursework Example | Topics and Well Written Essays - 750 words

Key Concepts in Management - Coursework Example is because machines are beneficial for increasing the overall efficiency but it cannot be considered as a tool to communicate with employees (Marchington & Wilkinson, 2008, pp. 56-57). On the contrary, organization provides an environment in which employees can enhance their competencies as well as develop their skills to sustain in the workplace for longer period of time. Machines are usually subjected to decreasing rate of productivity which is not true in context of an organization. A machine can be more powerful than an organization in the initial phases but in case of sustainability it cannot be considered to be effective. Employees or living components of an organization cannot be sustained by a machine for long run. As for sustainability productivity and efficiency are not the only vital components (Torrington, Hall & Taylor, 2005, pp.110-111). An effective operation is not enough to ensure longevity as other factors such as work collaboration, high adaptability, incorporating necessary changes etc., is equally important. It can be stated that external forces play a major role in ensuring longevity of a system. Modern organizations to some extent seem to be preoccupied with the idea of maintaining status quo in the industry. However risk is a factor which cannot be eliminated completely from the system. Status quo is often considered to be the most difficult element in terms of sustainability. In the present competitive environment organizations had to strive hard in order to maintain their respective status quo in the industry. However there is often a mindset developed that organizations are performing well and has effectively maintained their status quo. This can be considered to be a prison mindset as such situation is never real in the present business environment (Jackson, Schuler &Â  Werner, 2011, pp. 101-103). In certain context this form of prison mindset develops when a firm possesses a record of outstanding performance and has a reputed image
