Essay Examples on Othello Essay Example

Essay Examples on Othello Paper 1st Essay Sample on Othello 1. Othello is a very sympathetic character. He is tricked into thinking that his wife is having an affair with another man. Several other characters in the play, especially Iago, have such a grudge against Othello that they simply hate him and want to ruin his life. They don’t care who gets hurt in the process and are motivated by nothing but sheer selfishness. Iago is also highly duplicitous, and Othello actually trusted him. The audience has to feel sorry for Othello because he is severely persecuted, tricked, and deceived. He seems like a decent individual, too, in spite of the tragic ending of the drama. Othello stays strong throughout most of the play, defending himself gracefully in front of the court and only losing his temper at the end. He might not be aware of Iago’s plot but he might sense the persecution. He becomes weak at the end mainly because he buckles under the pressure of feeling deceived even though he believes Desdemonda deceived him and not Iago. When he commits suicide it is because he cannot live with himself after killing Desdemonda; he does not kill her out of cruelty but out of anguish. 2. One of the reasons why Othello believed that Desdemonda was unfaithful was because their relationship was new. They had not yet developed the trust that requires many years of marriage.

When confronted with the false evidence of the affair, Othello leapt to a conclusion without offering Desdemonda a chance to defend herself and without being willing to listen to her. His actions also suggest some sexism on his part: being more able to trust males than females based on the ingrained notion that females are morally corruptible. If I were in Othello’s place I would of course not commit murder. 2nd Essay Sample on Othello Othello is a play made by the great Shakespeare. It is about a tragic hero Othello and the lies and deceits surrounding him. Othello is a noble, honest character and still has the rugged qualities of a great soldier. He is truly one of the greatest characters in all literature. He has such outstanding characteristics, which makes this tragic end so painful. But it a tragic play and in the end Othello loses some of his outstanding qualities. In the beginning of the play Othello has it all. He is about to become the General and has the love of the fair Desdemona and they are getting married. Othello is manipulated by Iago just like everyone else in the play and is brought down to Iagos level. The downfall of Othello starts with the words of Desdemonas father Brabantio. Look to her, Moor, if thou hast eyes to see: She has deceived her father, and may thee. this puts in the back of Othellos mind the thought of Desdemona cheating on him. Iago will use that later on to help convince Othello that what he is saying is true. Othello acts as if he never heard it but he heard it all right. It will haunt him near the end of the play. The next step in Iagos plan and Othellos downfall is the scene where Cassio gets in a fight with Montano.Iago sets up Cassio, so that Othello will see Cassio drunk and might take away the title of lieutenant from Cassio. This begins the actual plan of Iago. From this point on Iago is thefirst person Othello will turn to for advice since Othellos once best friends and most trusted officer is found drunk and disrespectful.Othellos biggest weakness is his trust in everyone. Othello can not see the evil in people, which is the opposite of Iago.Iago will start to abuse this weakness and manipulate Othello to his liking. This is where we see another side of Othello.

Lipase Essays - Enzymes, Hydrolases, Lipase, Phenolphthalein

Lipase Essays - Enzymes, Hydrolases, Lipase, Phenolphthalein Background information: Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very specific and don't just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The activity of enzymes is affected by three factors; temperature, concentration, and pH. Changes in any of these factors affect the activity of an enzyme. Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach. Most people produce enough pancreatic lipase, but people with cystic fibrosis, Crohn disease, and celiac disease may not have enough lipase to get the nutrition they need from food. Uses of lipase: Most people do not need additional lipase. However, people with the following conditions may find lipase supplements helpful. Celiac disease, Indigestion, Cystic fibrosis Lipase supplements are usually derived from animal enzymes, although plant sources have become increasingly popular. Lipase may be taken in combination with protease and amylase enzymes. These pancreatic enzymes are available in tablet and capsule form. Research question: How different concentrations levels (1%, 2%, 3%, 4%, and 5 %,) of the enzyme lipase affect the enzymatic activity that will be allowed to act on the same amount of milk( Triglycerides are the major type of lipid in milk fat. Triglycerides are composed of three fatty acids covalently bound to a glycerol molecule by ester bonds) and the time taken for the phenolphthalein to turn from pink to white compared? Hypothesis: With higher lipase concentrations, there will be more active sites in the solution to be fit in by the substrates, which means more collisions between the active sites and the Substrates and quicker breakdown of lipids in the milk within shorter period of time. At Enzyme concentration of 1% or 2%, reactions can happen at a relatively slower pace, with lipids broken down and phenolphthalein turning from pink to white over a relatively longer time period. At 3%, enzyme activity will speed up with lipids broken down and phenolphthalein turning from pink to white over a relatively shorter time period. At 4% or 5%, enzyme activity will happen significantly faster. Important note: During the experiment, sodium carbonate solution and pH indicator, phenolphthalein will be added ahead of lipase enzyme; when the pH is below 8.2, phenolphthalein will turn from pink to colorless. Sodium carbonate solution is added in order to turn the solution alkaline and the indicator pink then back to colorless after lipase is added to catalyst the chemical reaction and speed up the breakdown of lipids into fatty acid in the milk. Fatty acid produced then is going to neutralize the solution with sodium carbonate solution added previously; phenolphthalein will finally turn from pink back to colorless. Variables: Independent Variables:Enzyme concentration- effectiveness of enzyme concentration will be tested at 1%, 2%,3%, 4%, and 5%. Enzyme lipase at the concentrations of 1%, 2%, 3%, 4% will be made by mixing lipase at 5% and distilled water; all these solutions will be contained in different beakers to keep them pure. In order to make 1% lipase, for each 1ml lipase, 4ml distilled water will be added and poured into a beaker; to make 2% lipase, for each 1ml lipase, 3ml distilled water will be added; to make 3% lipase, for each 1ml lipase, 2ml distilled water will be added; in order to make 4% lipase, for each 1ml lipase, 1ml distilled water will be added. Dependent variable: The time for the phenolphthalein to turn from pink to colorless will be taken using the stopwatch. Controlled Variables: Volume of milk used, pH of substrate, Volume of lipase solution, Temperature Controlled Variables: Controlled Variables: why they are controlled 1- Volume of the milkVolume of the milk used for every test will be kept constantly at 5ml; substrate concentration will be kept the same since full-cream milk will be used. Different volumes of milk will allow different amount of substrates to be contained in the milk. Therefore, more substrates contained in the milk will take it more time for the

Leadership and Symbolism Assignment Example | Topics and Well Written Essays - 500 words

Leadership and Symbolism - Assignment Example As it is common to most leaders, leadership involves persuading people to follow a common goal which is of importance to an organization, or a group. For this reason, leadership is mainly seen as a persuasion. For persuasion to take effect by a leader to the followers, there must be communication. Communication is, on the other hand, the transfer of symbols by the leadership so that the followers can perceive it well and bring understanding that is capable of enforcing leadership commands (Vickery, 2012). Symbolic framework provides space for inspirational leadership that is capable of turning around an organization, especially in terms of creating a culture of highly motivated employees after the employees have been demotivated through layoffs, terminations and going through issues of lack of trust. Starcorp as a company has undergone employee layoffs, terminations as well as issues of lack of trust on their leaders brought about by their previous leaders. At the same time, as Starc orp is now faced with the new NASA project that they need to take up, there is great need of making the employees work in harmony and in motivation as that is the only way to produce good results from their new project. It is easy for employees to lose trust on their leaders when they see them laying off other workers and terminating their contracts. When such have happened, there is need for leadership that can give assurance to the employees about their job security as well as better pay in order to make them motivated once again.

Examining Your Communitys Source of Energy Essay - 1

Examining Your Communitys Source of Energy - Essay Example Finally, this paper estimates the energy requirement for San Diego households and therefore recommends solar energy as the best feasible renewable energy to the community mainly due to low installation and operation costs and less impact on the environment. Energy is vital lifeblood of the San Diego community since it enhances business operations, used in operating machinery, moves goods and people, makes homes comfortable and powers the infrastructures that underpin the communities. In this regard therefore, the current energy supplies as well as future demand for energy are key issues in the binational region’s future. It is also important to note that the energy choices that are made today will significantly impact on tomorrow’s environment, economy and quality of life of the residents. Policy makers must therefore ensure that energy production, transmission and distribution do not impact on the environment and quality of life of the community living in San Diego. This paper focuses on the major sources of energy that powers San Diego’s community, how they impact on the environment and the alternative sources of energy that may be viable for the community. The major energy sources for the communities within San Diego ca are natural gas contributing to about 50%, coal contributing to 18% and nuclear contribution to approximately 15% of the overall energy supply (United States Power Report, 2014). The rest are large hydro electricity 10% while renewable sources of energy amount to 8% in total (United States Power Report, 2014). The major sectors that lead in energy consumption in San Diego include transportation accounting to over sixty percent followed by household, commercial and industrial sectors. As stated by United States Power Report (2014), this is a reflection of San Diego’s economy where since most residents within the community work in private automobiles with up to two occupants thus are commuters from home to work. Generally,

Black studies 1019--opinion paper--choosing two topics and describing Essay - 1

Black studies 1019--opinion paper--choosing two topics and describing their ideas and how they affected african americans in the - Essay Example The Sharing of Culture The exposure of one African ethnic group to the other had resulted to the sharing of cultures and traditions. As claimed by Michael Angelo Gomez, during the slavery period in America, the Africans coming from different cultural backgrounds had assembled themselves to form a single society of African Americans (88). It is contended that their cultural formation was not triggered by any form of racial discrimination but by the realization that they are different from the other people within the American society. What made them different is not just the color of their skin but their social status. So as to have a unified foundation for the expression of their common interest, the different ethnic groups decided to fuse their various traditions. It is in this sense that the Africans appreciated the advantages of creating a community. Nonetheless, it is worthy to emphasize that the fusion of the different beliefs and practices had not been easy for the different eth nic groups. Actually, the traditional people in Africa did not view the members of the other ethnic groups as belonging to their own (Freeman 25). They even had the propensity of seeing their ethnic group as more influential than the others. This suggests that during the process of cultural integration, the various African ethnic groups were struggling to make their beliefs and practices part of the new identity. Nevertheless, due to their slavery experience, these ethnic groups could have considered to be submissive to whatever way that could serve the best interest of all the Africans in America. The African American Music The formation of African-American music is one of the products of the cultural integration that the different ethnic groups had experienced and embraced during the slave era in America. After the abolition of slave trade in America, there had been many African-American singers and songwriters who became part of the American entertainment and music industry. As m embers of the African-American community, the African-American music artists are expected to express their cultural identity in their musical compositions and even in their everyday dealing. Their way of expressing the cultural identity of African-Americans has caught the public’s attention. The African-American music artists living in America have been subjected to a very controversial question, that is, whether they view themselves primarily as individuals of African descent who happened to be in the American soil or primarily as Americans who happened to be of African descent. A Discussion of the Distinction It is claimed that the new generation of African-Americans could consider themselves belonging to the second option. In a way, since they have been part of modern America, they have the tendency to behave in the American way. This connotes that for them, their American identity weighs more than their African ancestry. Their ancestral root has become a second or subsidi ary identity. Nonetheless, they still recognize the fact that they have a unique cultural origin. It is in this sense that they have the tendency to reshape and improvise a musical composition or simply â€Å"to blackenize† it, giving it an African-American touch (Maynard-Reid 71). Examples of African-American singers born during the post-slavery era are Michael Jackson and

Exhaust System For The LJMU

Exhaust System For The LJMU The FS event is held every year at Silverstone in the UK. The event was set up by the Institute of Mechanical Engineers (IMechE). Universities from around the world come to Silverstone to enter their cars in the event. Each team that enters FS is solely made up of students. There are a number of different classes which the car can be entered. These are Class 1, Class 1A and Class 2. LJMU is entering in to Class 1. Class 1 consists of a number of different events which can be broken down in to two categories, Static Events and Dynamic Events. The Static Events include, a presentation, Engineering Design and Cost Analysis. The Dynamic Events include an acceleration test, a skip-pad test, an autocross race and an Endurance race which includes a fuel economy test. The final exhaust design will be used in the 2011 LJMU FS car. For the exhaust to be used it must fully comply with the FS rules and regulations. The LJMU FS car is a group project and so it will be vital to the success of the exhaust system and the final car that communication is maintained. Formula Student 2010 LJMU competed in its first FS Class 1 event in 2010 and finished in 21st place. This was a great achievement for the university. Feedback was given to the university after the event from the FS judges. The feedback received was useful and has given areas of improvements for the car. One of the pieces of feedback was criticising the fact that the exhaust system didnt have a Lambda sensor to measure the levels of oxygen the in exhaust gas. This will be one area of improvement for FS 2011. Time Management To complete this project within the strict time limits a Gantt chart has been created. This can be seen in APPENDIX REFERENCE. Within the time 4 stages will be completed. There are analysis, design, verification and manufacture. FS Rules and Regulations To successfully create an exhaust system a number of rules need to be met. The rules and regulations were written by the Formula Society of Automotive Engineers (FSAE). These rules are in place to maintain a level playing field throughout the teams and to also ensure that safety standards are kept. The FS rules can be interpreted in different ways and so create different and interesting designs. To summarise a few rules, the exhaust has to exist within an area of 450 mm behind the centreline of the rear axle and 600 mm above the ground, the driver must be protected against heat and fumes and the sound must not exceed 100dBA. The engine size is also limited by FS rules. The rules state that an engine no bigger than 610cc can be used for the competition. The used for the engine must also pass through a 20mm restrictor. The full list of rules and break down which are relevant to this project can be found in ARTICLE 10: Exhaust System and Noise Control seen in APPENDIX REFERENCE. Design Restrictions As the exhaust will get very hot during running it is important that the exhaust pipes dont come in to contact or come too close to other engine peripherals such as electrical cables and fuel line. The driver will also be protected by a firewall in case of a fire or excess heat from the engine. As the fuels system, intake system and other peripherals have yet to be decided assumptions must be made in the routing of the exhaust system. The decision has been made to mount the engine front facing. This will mean that the exhaust ports are facing towards the front of the car and the intake ports are facing the back of the car. This decision has been made to simplify the design of the drive train to minimalize power lost and reduce the risk of failure. The design is also impacted by 20mm restrictor on the air intake which will also affect the exhaust system. Ricardo WAVE Ricardo WAVE Build will be used to fully model the exhaust system. Ricardo WAVE is an ISO 1D/3D engine and gas dynamics simulation package. WAVE is used in a number of different industry sectors all involved in simulating engine performance. It used from creating an initial design to the modifying an existing design without having to manufacture any components. WAVE only produces theoretical engine performance data and will need to be verified with experimental data. Ricardo WAVE is a sponsor in the FS event and so all FS teams have access to the software. Learning Ricardo WAVE Within the WAVE help file there is a list of tutorials which cover setting up and running an engine model. The tutorials range from beginner to advanced. The beginner spark ignition (SI) tutorial takes the user through the initial setup of an in-line, 4-cylinder 1.6L engine. Two WAVE tutorials have been completed these are the Introductory SI Tutorial and the Intermediate Concentric Silencer Tutorial. Going through the tutorials helped to give an idea of the different parameters that would need to be collected from the Honda CBR600RR engine. The tutorials also guide the user through the analysis of the model and how a change in the design affects output. Engine Selection The engine selection is partly governed by the FS rules and regulations as stated earlier. Due to the restrictions a decision was made to go for a reliable, powerful engine which is light weight. This lead to the Honda CBR600RR-4. The Honda is a 600cc performance motorcycle engine and so its power to weight ratio is high, which makes it perfect for the FS car. LJMU have used this engine for the past 2 years. The specification of the Honda CBR600-3 will be referenced to as the engine specification has not changed between 2003 and 2004. The CBR600RR engine is an 16-valve, in-line four cylinders, four stroke, with double overhead camshafts (DOHC) (Coombs, 2006). The Engine uses Programmed Duel Storage (PGM-DS) fuel injectors, two per cylinder, one upper and one lower. The lower injectors are used to enhance reliability, above 5500rpm the upper injectors are triggered and are used to improve top end horsepower (Torrance, 2003). A full specification of the standard CBR600RR can be found in APPENDIX REFERENCE. There are a number of different modifications that will take place on the engine by the FS event in 2011 and so the specification is subject to change. Changes that are being considered are an optimal air induction system with the 20mm restrictor, design and manufacture of a shallower sump, reduction in number of gears and modification of ratios and developing an optimised engine map. All of these changes are aimed at increasing performance of the engine for the required characteristics of the competition. Literature Review To generate the best performance from an exhaust system knowledge of a 4 stroke SI Internal combustion (IC) engine is needed. Four-stroke spark ignition (SI) engines The four-stroke SI engine has four different strokes as seen in Figure 1, Four-stroke IC Engine (Encyclopaedia Britannica, 2007) The four strokes are Intake, Compression, Power and Exhaust. For each turn of the crankshaft two strokes occur. The Intake stroke, also known as the Induction stroke, starts from Top Dead Centre (TDC). In this stroke the piston moves down, the intake value opens causing the air and fuel mixture to be drawn in to the combustion chamber. The volume of the air/fuel mixture drawn in to the chamber is known as the volumetric efficiency. If there is too much air in the mixture then the fuel will burn quickly increasing the pressure in the chamber too quickly leading to mechanical losses and misfiring. This is known as a lean fuel mixture and can lead damage the engine. If there is too much fuel in the mixture then all of the fuel will not be burnt leading to inefficiencies as unburnt fuel will be expelled through the exhaust valve. This will also lower the temperature and pressure in the chamber. This is known as a rich fuel mixture. The Compression stroke follows the induction stroke. The compression stroke starts from Bottom Dead Centre (BDC). The intake valve shuts and the piston starts to move back up the chamber. Just before the piston hits TDC the spark plug fires causing ignition. The Power stroke is where the piston moves down the chamber due to the increase in pressure and temperature from combustion. When the piston hit BDC the exhaust valve opens. The Exhaust stroke forces the gasses out of the combustion chamber through the exhaust valve after the Power stroke. At the end of the exhaust stroke the exhaust valve closes and the cycle starts again. Any exhaust gasses left in the chamber will contaminate the next intake of fuel and will reduce the power output. As only one stroke generates any power (Power stroke), energy has to be stored in a flywheel to move the piston for the remaining three strokes. (Stone, 1999) Engine Thermodynamics An IC engine whether it is a 4 stroke or a 2 stroke is a non-cyclic process. However as the nitrogen in the fluid is virtually unchanged it can be argued that the process is cyclic. This makes calculating the thermodynamic efficiencies much easier as it can be compared to the Otto cycle. Performance To calculate the performance and effectiveness of the exhaust system a number of different parameters will need to be defined. Exhaust Design There are two main designs for exhaust systems, exhaust manifold and exhaust header. Both designs have different pros and cons depending on the different requirements. A standard exhaust manifold can be seen in Figure 2, Standard Exhaust Manifold (Monster Autoparts) This Exhaust is made from cast iron, and so it is perfect for production vehicles as casting is inexpensive if the cast is only used on a large scale. However for a one off production exhaust system it would be expensive. Exhaust headers Figure 3 on the other hand are comparatively inexpensive to produce a one off design as no mould needs to be created and the pipes can be simply bent and cut in to shape. Manifolds are also inefficient compared to exhaust headers. This is due to the air flow in a manifold. When the exhaust gas enters the manifold back pressure is built up. This back pressure restricts the flow for the next wave of exhaust gas. This means that the piston has to work harder to force the exhaust gas out of the cylinder leading to power loss. This back pressure can be reduced or eliminated using exhaust headers by taking advantage of the timing. This is known as exhaust pulsation. To fully understand pulsation it is important to explain the exhaust system shown in Figure 3. This design is a 4-2-1 exhaust. Different exhaust designs can be found in APPENDIX REFERENCE. As can be seen each exhaust port has its own header. Header pipes 1 and 2 join and header pipes 3 and 4 join. These joints are known as collectors which then form the secondary headers. The 2 secondary headers then move in to the final collector and form the downpipe. The firing order of the Honda CBR600 engine is 1-2-4-3 (Coombs, 2006). Improving Engine Performance To improve the performance of the engine pulsation can be used. Pulsation is where Exhaust Pulsation Exhaust Gas Turbochargers There are two different types of exhaust gas turbocharging. These are Pulse Turbocharging and Constant Pressure Turbocharging. Exhaust Gas Recirculation Exhaust Gas Recirculation (EGR) is where a small portion of the exhaust gas (5-10%) is fed through a valve back in to the inlet manifold ready for the intake stroke. This helps to decrease emissions of NOx (nitric oxcide and nitrogen dioxide) as the amount of fresh fuel drawn in to the cylinder in replaced with exhaust gas. Between 5 and 10% of EGR is likely to halve the NOx emissions (Stone, 1999). EGR increases intake manifold pressure. The higher intake manifold pressure leads to a reduction in the charge cycle work and this lowers the fuel consumption. During EGR the peak combustion temperature is reduced due to the exhaust gas not being used during combustion which will cause less energy to be produced. (Bosch, 2007) EGR can cause misfire and partial burns to occur as the amount of fuel in the cylinder is reduced, causing a lean mixture. Data Collection Engine Geometry To create an accurate model in WAVE geometry from the CRB engine has to be collected. This was done in a number of different ways. A list of geometry needed for WAVE can be found here APPENDIX REFERENCE. A new head from a CRB engine was purchased and was used to collect the relevant information. A new head was purchased as the tests that were carried out on the head would require taking sections, which would destroy the head beyond repair.

Alzheimers Disease :: Alzheimers Disease Essays

Alzheimer’s disease is a slowly progressive, degenerative disorder of the brain that eventually results in abnormal brain function and death. The disease was first described in 1907 by a German physician, Dr. Alois Alzheimer(1864-1915). In the neurological autopsy on the brain of a 56-year-old woman Auguste D., of Frankfurt, who died after several years of progressive mental deterioration marked by increasing confusion and memory loss. Taking advantage of a then-new staining technique, he noticed an odd disorganization of the nerve cells in her cerebral cortex, the part of the brain responsible for reasoning and memory. The cells were bunched up like a rope tied in knots. He termed the strange nerve bundles neurofibrillary tangles. He also noted an unexpected accumulation of cellular debris around the affected nerves, which he termed senile plaques. In a medical journal article published in 1905, Alzheimer speculated that the nerve tangles and plaques were responsible for the women’s dementia. Alzheimer’s disease is a disorder marked by a gradual decline in brain function that gets worse with time. It used to be assumed that this change was a normal part of aging that we called senility. Some people develop this condition when they are as young as 40 years of age. However, the disease is most common in persons over the age of 65. It is estimated that approximately 10 percent of persons over 65 years of age may have Alzheimer’s disease and that in persons over the age of 85, up to 50 percent may be affected. Alzheimer’s disease is not a normal part of the aging process. It is not contagious, and it is not known how it can be prevented. While the physical changes in the brain are very similar among different people the behavioral and psychological symptoms that result are complex and may differ from person to person(Kawas, 80). These symptoms lead to a form of dementia which is the loss of mental skills and abilities, including self-care capabilities. As Alzheimer’s disease progresses, these losses will result in total dependency for even the simplest activities(Erickson, 149).   Ã‚  Ã‚  Ã‚  Ã‚  Alzheimer’s disease usually comprises of three stages. The first being the onset stage. The symptoms of the onset stage often appear very gradually. There may be some minimum memory loss, particularly of recent events. The individual may experience difficulty in finding the right words to use during casual conversations. Work performance may begin to deteriorate and changes in behavior may start to become obvious.

Information Technology in India Essay

India is one of the great standup country in the field of science and technology. every year india produces more than 500 thousands engineers. No doubt it is a bulk producers of scientists and technologists. Information Technology remain the backbone of the economical growth of India. and you can see it from the observed facts of exports. The share of IT in exports has increased by 17% from 1990 to 2001. IT based sectors such as Backoffice, remote maintainence, accounting, public service, medical, insurence and other bulk processiong fields are rapidly expending. Indian companies such as HCL, WIPRO, INFOSYS, TCS are today’s tough competitors for the other IT organizations. History of Information Technology in India The setup of IT in India was done by the Tata group in association with the Burroughs at Mumbai in 1967. The first software export zone SEEPZ was setup in 1973 this was what we can call the old avatar of the IT parks. at that time 80% of india’s software were exported from there. The indian government baughtEVSEM computers from soviat unions in 1968 which was used in big organizations only for the technological and scientific researchs. After the freedom of india in aug 1947 it was an economically beleaguered country. but due to the efforts of PM late. sir Jawaharlal Nehru india very repidly become a wide scientific work-field, such big that it was ranked 3rd after the USA and Soviat Unions. But due to the production of more engineers then country can consume the number of emigrants increased and this supported forigen countries to get a large step ahead from india. The most of the helping hands in the US’s scientific and technological improvement was Indian, in association with the california’s silicon valley. During this time the creation of new organization was in progress. with enhancement of IT in india some well known groups stood-up some of the names are, National Informatic Center, Tata infotech, Patni Computers, Wipro, Infosys etc. In 1991 Department of electronic created a corporation called Software Technology Parks of India which are owned by govt. of India. They provide VSAT communication. and after 1993 Govt. allowed pvt. companies to own dedicated links. VSNL was first to introduce Gateway E-Mail service with the 64kbps leased line service. It was the ministry of Atal Bihari Vajpai who significantly improved the IT in india by placing development of IT in the five major priorities and form National Task Force on IT and software development. and within 90 days of the creation of NTF the suggested 108 recommendation for IT sector.

Prohibition Era Timeline

Prohibition Era Timeline The Prohibition era was a period in the United States, lasting from 1920 to 1933, when the production, transportation, and sale of alcohol was outlawed. This period began with the passage of the 18th Amendment to the U.S. Constitution and was the culmination of decades of temperance movements. However, the era of Prohibition was not to last very long, for the 18th Amendment was repealed 13 years later with the passage of the 21st Amendment.

Many early advocates of temperance were Protestants who believed alcohol was destroying public health and morality. 1830s The first temperance movements begin advocating abstinence from alcohol. One of the most influential dry groups is the American Temperance Society. 1847 Members of Maines Total Abstinence Society convince the state government to pass the Fifteen Gallon Law, the first prohibition law. The legislation banned the sale of alcohol in amounts smaller than 15 gallons, effectively limiting access to alcohol to the wealthy. 1851 Maine passes the Maine law, banning the production and sale of alcohol. The law includes an exception for medicinal uses. 1855 By 1855, 12 other states have joined Maine in banning the production and sale of alcoholic beverages.

Activists try to enforce the law using a number of different techniques. The most peaceful demonstrate outside saloons; others attempt to interfere with business and destroy bottles of liquor. 1893 The Anti-Saloon League is formed in Oberlin, Ohio. Within two years, the group becomes an influential national organization lobbying for prohibition. Today, the group survives as the American Council on Alcohol Problems. 1917 December 18: The U.S. Senate passes the Volstead Act, one of the first significant steps toward the passage of the 18th Amendment.

Application paper 1 - Essay Example Correspondingly, the fundamental features of the theory will be elaborated in this thesis, along with their application in the real life experiences. Criticisms of the theory will also be paid due significance in context to assess the applicability of the theory. DISCUSSION Key elements of the theory. SCT, as described by Griffin (247-250), is a universal theory within the broad framework that accounts for human communication. Precisely, SCT focuses on learning the sharing process of emotions and values in a small group, defining those as fantasies. The SCT communication is also used to observe the cohesiveness of a small group, wherein it is assumed that individuals will tend to dramatize their messages to a larger extent when confident in the group. Notably, communication is used to create a bond between small groups of people. The theory revolves around the emotions and fantasies of the people in a group wherein the conceptual framework of the theory attempts to analyze shared sym bolic meaning, which lies at the fantasy theme a person desires. The conversation begins with a fantasy of a person and continues with different opinions of the people in the group. SCT also helps to identify the symbolic reality that the member of the group shares through his/her conversation (Young, â€Å"Bormann's Symbolic Convergence Theory†). As argued by Griffin (247-250), SCT can be extremely useful to obtain critical understanding of the views and the thoughts of different persons in a group. SCT is principally based on the ideas of the member in a group who exchange their fantasies in order to formulate a cohesive group framework. The fantasies involve the emotion of the person supported by the group; it helps to understand the feeling and emotions of different individuals. Contextually, the fantasy chain can be considered as a positive response to the initial fantasy by the member of the group. It is in this context that symbolic convergence helps to form a cohesive bond and create a sense of togetherness in the group through the symbolic communication as described in SCT. The views and opinions of every individual are given emphasis based on the initial fantasy. Conceptually, SCT aids to recognize how the group associates, interacts and offers a way of inspecting small group culture. Also, this theory also makes it easier to understand who the active member is and is supporting the theme of the fantasy, building a fantasy chain (Young, â€Å"Bormann's Symbolic Convergence Theory†). A brief background of the situation. It was a normal working day when I, with my colleagues, was discussing about the upcoming salary hikes that were to be declared on the basis of our performances throughout the year. Undoubtedly, everyone in the group had great expectations and desires with the salary hike. In the middle of the conversation, one of my colleagues suddenly fantasized that with the aid of his increased salary and some help from loan facilitie s, he plans to purchase a duplex in one of the posh areas of the US within the next two years. This fantasy statement made the atmosphere in the work environment much informal, where the conversation was turning to a more comfortable level and
