E-commerce have significantly transformed commerce, in deed beforehand, commerce involved that sale and purchase of good and service using traditional marketing tools, marketers were influencing consumer behavior via advertising. Consumers were unable to have an accurate and symmetric information about the price, the quality, the cost of the product that they were buying, as a result, seller s were taking advantage of information asymmetry to raise their profit. Whereas, e-commerce has brought up a significant reduction in information asymmetry between market forces and allowed markets to get closer to perfect market competition. However, e-commerce allows sel lers to collect more precise information about consumer behavior and preferences which has given them theShow MoreRelatedThe Impact Of Technology On Managerial Accounting Essay1863 Words   |  8 PagesIntroduction Technological advances have dramatically changed many aspects within organizations and influenced how they operate today.

One-Dimensional Man - 1360 Words

The introduction of Herbert Marcuse’s book, â€Å"One-dimensional Man,† shows us the problem that a democratic society creates. Though this book was written back in 1964, many can agree that what he says is true in today’s society. Different scenarios are also brought up to show us how things will be affected due to the advancements of technology. Marcuse wants us to see what will happen and what has happened to society through a series of changes. Marcuse talked a lot about the necessities and luxuries of life. He called these the â€Å"true needs† and the â€Å"repressive needs.† He makes it a point to show us that the changes in society cause us to think differently. Most people are beginning to mistaken the â€Å"true needs† with the â€Å"repressive needs.†Ã¢â‚¬ ¦show more content†¦By this he wants us to realize that humans will soon be replaced by technology. There would be no need for people to be around factories anymore because everything can be done much faster and much more efficient with machines. This is the type of society that we are heading into. This is all due to the people that own these factories. The uses of machines have proven to be much more efficient and much more productive. Humans just can’t perform certain tasks that are needed to mass produce products. They just may be able to but the quality of the work wouldn’t compare to that of a machine’s wo rk. â€Å"Today political power asserts itself through its power over machine process and over the technical organization†¦.† (3). We can all agree that this statement still holds true today. The executive decisions, which are made in today’s society, are all made by those who own major companies or corporations. They have the most power because they have the most money. Their factories are mainly machines that create their product. Though they still require some manpower to run their system, they mainly rely on their machines, These select few people utilize the full potential use of technical, scientific and mechanical productivity (3).

DRINKING Essay Example For Students

DRINKING Essay Despite a minimum legal drinking age of 21, many young people in the United States consume alcohol. Some abuse alcohol by drinking frequently or by binge drinkingoften defined as having five or more drinks* in a row. A minority of youth may meet the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence (1,2). The progression of drinking from use to abuse to dependence is associated with biological and psychosocial factors. This Alcohol Alert examines some of these factors that put youth at risk for drinking and for alcohol-related problems and considers some of the consequences of their drinking. For many people, the facts about alcoholism are not clear. What is alcoholism, exactly? How does it differ from alcohol abuse? When should a person seek help for a problem related to his or her drinking? The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has prepared this booklet to help individuals and families answer thes e and other common questions about alcohol problems. The information below will explain alcoholism and alcohol abuse, symptoms of each, when and where to seek help, treatment choices, and additional helpful resources. For most people, alcohol is a pleasant accompaniment to social activities. Moderate alcohol useup to two drinks per day for men and one drink per day for women and older people (A standard drink is one 12-ounce bottle of beer or wine cooler, one 5-ounce glass of wine, or 1.5 ounces of 80-proof distilled spirits) is not harmful for most adults. Nonetheless, a substantial number of people have serious trouble with their drinking. Currently, nearly 14 million Americans1 in every 13 adultsabuse alcohol or are alcoholic. Several million more adults engage in risky drinking patterns that could lead to alcohol problems. In addition, approximately 53 percent of men and women in the United States report that one or more of their close relatives have a drinking problem. The consequences of alcohol misuse are seriousin many cases, life-threatening. Heavy drinking can increase the risk for certain cancers, especially those of the liver, esophagus, throat, and larynx (voice box). It can also cau se liver cirrhosis, immune system problems, brain damage, and harm to the fetus during pregnancy. In addition, drinking increases the risk of death from automobile crashes, recreational accidents, and on-the-job accidents and also increases the likelihood of homicide and suicide. In purely economic terms, alcohol-use problems cost society approximately $100 billion per year. In human terms, the costs are incalculable. Alcoholism, which is also known as alcohol dependence syndrome, is a disease that is characterized by the following elements: ? Craving: A strong need, or compulsion, to drink. ? Loss of control: The frequent inability to stop drinking once a person has begun. ? Physical dependence: The occurrence of withdrawal symptoms, such as nausea, sweating, shakiness, and anxiety, when alcohol use is stopped after a period of heavy drinking. These symptoms are usually relieved by drinking alcohol or by taking another sedative drug. ? Tolerance: The need for increasing amounts of alcohol in order to get high. Alcoholism has little to do with what kind of alcohol one drinks, how long one has been drinking, or even exactly how much alcohol one consumes. But it has a great deal to do with a persons uncontrollable need for alcohol. This description of alcoholism helps us understand why most alcoholics cant just use a little willpower to stop drinking. He or she is frequently in the grip of a powerfu l craving for alcohol, a need that can feel as strong as the need for food or water. While some people are able to recover without help, the majority of alcoholic individuals need outside assistance to recover from their disease. With support and treatment, many individuals are able to stop drinking and rebuild their lives. Many people wonder: Why can some individuals use alcohol without problems, while others are utterly unable to control their drinking? Recent research supported by NIAAA has demonstrated that for many people, a vulnerability to alcoholism is inherited. Yet it is important to recognize that aspects of a persons environment, such as peer influences and the availability of alcohol, also are significant influences. Both inherited and environmental influences are called risk factors. But risk is not destiny. Just because alcoholism tends to run in families doesnt mean that a child of an alcoholic parent will automatically develop alcoholism. .u7125f8bbc632171c018b665d65613540 , .u7125f8bbc632171c018b665d65613540 .postImageUrl , .u7125f8bbc632171c018b665d65613540 .centered-text-area { min-height: 80px; position: relative; } .u7125f8bbc632171c018b665d65613540 , .u7125f8bbc632171c018b665d65613540:hover , .u7125f8bbc632171c018b665d65613540:visited , .u7125f8bbc632171c018b665d65613540:active { border:0!important; } .u7125f8bbc632171c018b665d65613540 .clearfix:after { content: ""; display: table; clear: both; } .u7125f8bbc632171c018b665d65613540 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u7125f8bbc632171c018b665d65613540:active , .u7125f8bbc632171c018b665d65613540:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u7125f8bbc632171c018b665d65613540 .centered-text-area { width: 100%; position: relative ; } .u7125f8bbc632171c018b665d65613540 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u7125f8bbc632171c018b665d65613540 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u7125f8bbc632171c018b665d65613540 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u7125f8bbc632171c018b665d65613540:hover .ctaButton { background-color: #34495E!important; } .u7125f8bbc632171c018b665d65613540 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u7125f8bbc632171c018b665d65613540 .u7125f8bbc632171c018b665d65613540-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u7125f8bbc632171c018b665d65613540:after { content: ""; display: block; clear: both; } READ: John Biggers: The Impact and Significance of Symbolization in African American Art EssayAlcohol abuse differs from alcoholism in that it does not include an extremely strong craving for alcohol, loss of control, or physical dependence. In addition, alcohol abuse is less likely than alcoholism to include tolerance (the need for increasing amounts of alcohol to get high). Alcohol abuse is defined as a pattern of drinking that is accompanied by one or more of the following situations within a 12-month period: ? Failure to fulfill major work, school, or home responsibilities; ? Drinking in situations that are physically dangerous, such as while driving a car or operating machi nery; ? Recurring alcohol-related legal problems, such as being arrested for driving under the influence of alcohol or for physically hurting someone while drunk; ? Continued drinking despite having ongoing relationship problems that are caused or worsened by the effects of alcohol. While alcohol abuse is basically different from alcoholism, it is important to note that many effects of alcohol abuse are also experienced by alcoholics. How can you tell whether you, or someone close to you, may have a drinking problem? Answering the following four questions can help you find out. (To help remember these questions, note that the first letter of a key word in each of the four questions spells CAGE.) ? Have you ever felt you should Cut down on your drinking? ? Have people Annoyed you by criticizing your drinking? ? Have you ever felt bad or Guilty about your drinking? ? Have you ever had a drink first thing in the morning to steady your nerves or to get rid of a hangover (Eye opener)? One yes response suggests a possible alcohol problem. If you responded yes to more than one question, it is highly likely that a problem exists. In either case, it is important that you see your doctor or other health care provider right away to discuss your responses to these questions. He or she can help you determine whether you have a drinking problem and, if so, recommend the best course of action for you. Even if you answered no to all of the above questions, if you are encountering drinking-related problems with your job, relationships, health, or with the law, you should still seek professional help. The effects of alcohol abuse can be extremely seriouseven fatalboth to you and to others. Acknowledging that help is needed for an alcohol problem may not be easy. But keep in mind that the sooner a person gets help, the better are his or her chances for a successful recovery. Any reluctance you may feel about discussing your drinking with your health care professional may stem from common misconceptions about alcoholism and alcoholic people. In our society, the myth prevails that an alcohol problem is somehow a sign of moral weakness. As a result, you may feel that to seek help is to admit some type of shameful defect in yourself. In fact, however, alcoholism is a disease that is no more a sign of weakness than is asthma or diabetes. Moreover, taking steps to identify a possible drinking problem has an enormous payoffa chance for a healthier, more rewarding life. When you visit your health care provider, he or she will ask you a number of questions about your alcohol use to determine whether you are experiencing problems related to your drinking. Try to answer these ques tions as fully and honestly as you can. You also will be given a physical examination. If your health care professional concludes that you may be dependent on alcohol, he or she may recommend that you see a specalist in diagnosing and treating alcoholism. You should be involved in making referral decisions and have all treatment choices explained to you. The nature of treatment depends on the severity of an individuals alcoholism and the resources that are available in his or her community. Treatment may include detoxification (the process of safely getting alcohol out of ones system); taking doctor-prescribed medications, such as disulfiram (Antabuse) or naltrexone (ReViaTM), to help prevent a return to drinking once drinking has stopped; and individual and/or group counseling. There are promising types of counseling that teach recovering alcoholics to identify situations and feelings that trigger the urge to drink and to find new ways to cope that do not include alcohol use. Any of these treatments may be provided in a hospital or residential treatment setting or on an outpatient basis. Because the involvement of family members is important to the recovery process, many programs also offer brief marital counseling and family therapy as part of the treatment process. Some programs also link up individuals with vital community resour ces, such as legal assistance, job training, child care, and parenting classes. Virtually all alcoholism treatment programs also include meetings of Alcoholics Anonymous (AA), which describes itself as a worldwide fellowship of men and women who help each other to stay sober. While AA is generally recognized as an effective mutual help program for recovering alcoholics, not everyone responds to AAs style and message, and other recovery approaches are available. Even those who are helped by AA usually find that AA works best in combination with other elements of treatment, including counseling and medical care. Bibliography:

This is why we measure hardness in terms of CaCO3. The concentration of the Ca2+ ions is greater than the concentration of any other metal ion in our water. The determination of water hardness is routinely used to measure the quality of water that the general public uses. Originally, water hardness was defined as the measure of the capacity of the water to precipitate soap. Hard water is not a health hazard since the main chemical in hard water is calcium. People regularly take calcium supplements. In fact, hard water can be a source of necessary minerals (calcium and magnesium) that is necessary for good health. Indeed, the National Academy of Science go so far as stating that that consuming extremely hard water could be a major contributor of calcium and magnesium to the diet. The problem with hard water is that it cause soap scum, clog pipes and clog boilers. Soap scum is formed when the calcium ion binds with the soap. This causes an insoluble compound that precipitates to form the scum you see. Soap actually softens hard water by removing the Ca2+ ions from the water. When hard water is heated, CaCO3 precipitates out, which then clogs pipes and industrial boilers. This leads to malfunction or damage and is expensive to remove. There are two types of water hardness, temporary and permanent. Temporary hardness is due to the bicarbonate ion, HCO3-, being present in the water. This type of hardness can be removed by boiling the water to expel the CO2, as indicated by the following equation: HCO3- (aq) ? H2O (l) + CO2 (g). Because bicarbonate can be removed it is classified as temporary hardness. Permanent hardness is due to the presence of the ions Ca2+, Mg+2, Fe3+ and SO4-2. Because boiling cannot eliminate this type of hardness, the water is said to be permanently hard. The table below shows the degree of hardness of the water in terms of its calcium carbonate concentration in ppm and grains. Hardness rating Soft Medium Hard Hard Very Hard Concentration of Calcium Carbonate (mg/L or ppm) 0 75 75 to 150 150 to 300 300 and greater Concentration of Calcium Carbonate (grains/US gallon) 0 to 5. 2 5. 2 to 10. 5 10. 5 to 21 21 and greater Permanent hardness is usually determined by titrating it with a standard solution of ethylenediamminetetraacetic acid, EDTA. The EDTA is a complexing, or chelating agent used to capture the metal ions. This causes water to soften, but the metal ions however, are not removed from the water. EDTA simply binds the metal ions so that the ions do not precipitate to form soap scum. EDTA is a versatile chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. Chelating agents are multidentate ligands. A ligand is a substance that binds with a metal ion to form a complex ion. Multi-dentate ligands are many clawed, holding onto the metal ion to form a very stable complex. EDTA can form four or six bonds with a metal ion. It is frequently used in soaps and detergents because it forms complexes with calcium and magnesium ions. The ions in hard water are bound to the EDTA and cannot interfere with the cleaning action of the soap or detergent. EDTA is also used in foods. Certain enzymes are responsible for food spoilage. EDTA is used to remove metal ions from these enzymes. It is used to promote color retention in dried bananas, beans, chick peas, canned clams, pecan pie filling, frozen potatoes and canned shrimp. It is used to improve flavor retention in canned carbonated beverages, beer, salad dressings, mayonnaise, margarine, and sauces. It inhibits rancidity in salad dressings, mayonnaise, sauces and salad spreads. In this lab you will be asked to determine the total permanent hardness. EDTA grabs all the metal ions in the water, not just the Ca2+ ions. This gives us a value that is not truly the concentration of Ca2+ ions. This causes an experimental error of about 1%, which is acceptable due to the fuzzy endpoints in this type of titration. Erio-T indicator or Eriochrome Black-T indicator is used in this titration. When it is chelated or acidifies, it produces a Pink-Red solution. When it is not chelated and under basic conditions it is Blue. The three pictures show the end point in this titration. There is a 1-drop difference of 0. 01 M EDTA between the first and second pictures and between the second and third pictures. Two or three seconds were allowed for colors in the second and third pictures to develop after adding the additional drop. In each case the solution was thoroughly mixed. This color change from wine red to violet to blue is due to the compact nature of the complex. Experiment. EDTA Titration of Ca2+ in an unknown solution PROCEDURE Modified 9/2012 1. Dry Na2H2EDTA. 2H2O (FM 372. 24) at 80 ° C for 1 h and cool in the desiccator. Accurately weigh out ~ 0. 6 g and dissolve it with heating in 400 mL of water in a beaker. Cool to room temperature pour into a 500-mL volumetric flask. , mix and dilute to the mark. 2. You should practice finding the end point several times by adding a little tap water in a clean beaker and titrating with EDTA. Save a solution at the end point to use as a color comparison for other titrations. 3. Pipet a 1-mL sample of unknown into a 250-mL flask and fill to the mark with deionized water. Mix thoroughly. From this 250-mL stock solution draw 4, 50mL aliquot samples and place each aliquot in 250mL Erlenmeyer flasks. To each sample, add 3 mL of pH 10 buffer and 6 drops of Eriochrome black T indicator. To the first 50-ml solution, titrate with EDTA from a 50-mL buret and note when the color changes from wine red to blue. 4. Repeat the titration with the next three samples to find an accurate value of the total Ca2+ concentration. Perform a blank titration with 50 mL of distilled water and subtract the value of the blank from each result. 5. Upon completion of the experiment, discard all solution in a chemical waste bottle and wash out the glassware. Be sure to dry your buret in the upside down position. _________________________________________________________ Calculations – Analysis: Analyte Ca2+ The reaction of Ca2+ ions with H2EDTA2- takes place with a 1:1 stoichiometric ratio: Ca2+ + EDTA2- ?

Doll House By Ibsen Essays - A Dolls House, , Term Papers

Doll House By Ibsen Helmer is a successful bank lawyer in the drama "A Doll House" written by Henrik Ibsen. His wife's name is Nora. She is a housewife with three children and gets help raising them from her maid Helen. Nora and Helmer are both busy people within their lives. Little do they know that their marriage is not safe due to the fact that it is not given first priority in the lives they led. The action takes place in their home. Helmer is very protective when it comes to the family image that is portrayed to the public. This is because his career, as a lawyer, depends on it. He feels that he should have a perfect public image for the sake of his career and not his family, since that is what comes first in his life. This is seen when he discovers a letter from a bank that his wife, Nora, gets a loan from. He finds out that the loan was acquired illegally through forgery. She uses her father's signature. Helmer immediately strips her of all her rights to him as his wife and to the children as their mother. He does not ask for divorce since this will not be a good public image for his career, instead he asks her to have a separate room from his and limits her time with the children. Helmer is the rule maker of his house. He meticulously gives details on how he wants his house run. He has set time for everything, when the meals are prepared, when the children should go to sleep, when they should wake up, what to eat, when to check the mail etc. This is probably the reason why he is successful in his career. He is again putting his career as first priority and uses the principal that he applies to it in the family. Helmer has an office in the house of with he gives limited accesses to his wife, Nora. He treats her as if she was one of his children instead of "his wife". He entertains his official friends in the office in closed-door sessions and usually doesn't fill in his wife on his business. Career comes first for Hemler. The key to the mailbox is in the hands of Hemler. It looks like he does not take his wife as an equal by not giving her a spare key. He wants to be the first one to handle all the mail, scans the letters in the box and then distributes them to the appropriate people. His wife again is placed second to his business. Nora, Helmer's wife is also very protective when it comes how her husband views her. I see this when she hides the fact that she is having chocolate, which is forbidden in the household. She would rather let Dr. Rank, a family friend, know about the chocolate and not her husband. The doctor actually helps her to hide the package when Helmer walks into the living room. She also puts him in second place in her life. Nora also tells her friend Mrs. Linde about the money that she squeezes out of her house hold budget to pay for the loan she took from the bank. She does not tell her husband about the loan because she knows how he will react towards her and the issue. She protects herself instead of their relationship, putting their marriage in second place. The family friend doctor tells Nora how he has been in love with her for a long time. She reacts negatively letting Dr. Rank know that she will not tolerate his behavior. She keeps it from her husband since she wants to maintain an innocent view from him. The hiding of such issues from Helmer is first priority instead of her marriage. Nora is caught red-handed lying about the visit of Nis Krogstad, the banker. Nis is responsible for the Nora's loan. Helmer asks about the banker's visit and she denies the fact that he had come the their house. She is constantly lying just to save herself from changing her husbands view towards her. The blow to their marriage happens when Helmer discovers that his wife forged a bank document to get a loan. He gets angry and strips her of all her motherly and wife rights. Another letter shows up and clears them form the forgary He changes immediately and reinstats Nora back to her postion in their home. This clearly shows

The New Life Essay Example

The New Life Essay Example The New Life Essay The New Life Essay I believe that most of the people from other countries came to the United States to have the better quality of life. For me, I had no choice but to follow my parents step to come to the United States during young age, not knowing what was going on. I was 11 years old when I came to the United States. Walking throughout in the aisle of the airplane made my heart raised faster than was usual. I didnt want to come to the US, leaving everything behind such as, friends, families, and my sweet home but once again I didnt have any rights to hold myself back in Korea. But when I was on the plane, things got changed. I was actually imagining all of the good things about US that I saw from the American movies. Therefore, I did have some positive thoughts about coming to the US. I was excited and couldnt wait to see what it was like to be in the US. But when my mom grabbed me from behind and whispered in my ear saying, Son this is your new home and I would like for you to start your new life here and that made me feel bit terrible. I wasnt a good kid in school when I was in Korea. I was always making troubles and went through probably more things then the normal kids did around in my age. I guess that made my parents decide to move to the US. My life in the US was different, I didnt have friends, couldnt speak the language, and I was all left alone. I realized how greedy little kid I was in Korea and I discovered this when I went through the loneliness times. American schools were easy for me and it was a perfect place for me to start all over. Teachers liked me because I did everything that they asked me to do, or at least did the stuff that they least required for students to do. One day I realized that, God was giving me an opportunity. And God gave me the time to look back to see what Ive done in my past that wasnt important and gave me the time to think ahead for the future. I was given a second chance to have a whole new life. I didnt have a reason or purpose when I came to the US, but I found the dream that I wanted to achieve in my life. It did take me awhile to move my foot in the right direction but now I know where I am heading for, to become a business man. I decided to become a business man because I want to make tones of money. Reason I want tones of money is to support my family in the future, in a good condition environment, so that my children wont have to experience what I experienced in my childhood. I want my generations to get good education supports and comfortable lives so that they can pass it on to their generations as well. Now that I am currently attending at Pasadena City College as a full time student, I am going to give my best shots in every subjects and head for all As. After getting my requirement credits here in PCC, I am planning to transfer to the University of Southern California College to productively attain my degree for business for my career. I am very thankful to my parents because they have brought me here. I am also very thankful once again because if I or my parents couldnt decide to come to the US, I wouldnt have the chance to experience more opportunities that are open in the US and challenge others as I grow under the educational system in America.

Assignment 1 F&A Research Paper Example | Topics and Well Written Essays - 500 words

Assignment 1 F&A - Research Paper Example Nonetheless, the executive are predicting low consumer confidence and high unemployment rate as two most important factors that will hinder the recovery of the retail industry. (KPMG, 2012) (Farfan, 2011) Note 1 to the financial statements provides a complete description of the RadioShack Corporation’s business. The company deals in electronic items and services through 4,395 retail stores under its brand name in the US. The company also operates in Puerto Rico, Virgin Islands and Mexico. In 2009, the company launched ‘Target Mobile Centers’ to increase their sales and revenue. However, due to its failure, the company has decided to wind up these centers by the first quarter of 2013. It is very important to understand this note because its helps to identify and comprehend the business operations of the company and its future plans of discontinuation of any product line. (RadioShack Corp. Annual Report, 2012) Best Buy and Wal-Mart are two of the important competitors of RadioShack Corporation because they tend to have the same business as well as operate in the same environment. This will allow us to compare their financial and non financial metrics against each other such as profitability, efficiency, leverage and earning potential. Similarly, through a survey, the position of the RadioShack can be compared against its competitors in the consumers’ minds. Compared to the industry average debt to total assets ratio of 0.72, RadioShack Corporation has a better financial position. The company’s 61% of the assets are financed by debt. However, RadioShack Corporation is highly leveraged company as compared to industry benchmarks. The company has raise $1.58 of debt for every $1 of equity in the company as compared to $1.2 raised by the industry. This signifies an increased riskiness in the company and a poor rating amongst the external stakeholders. (Bloomberg Businessweek,

Some suggest that politics has become a minor form of show business Essay

Some suggest that politics has become a minor form of show business. Do you agree with this Consider the media-ization of politics in your answer - Essay Example The leader of present times is one who is in the eyes and minds of the commoners, no matter he does some good for the society or otherwise. (Schapiro, 1950) What people want from the politics of today is sensation, however deep down inside they want true democracy for their own betterment but then again everyone loves to gossip and politics is the favorite amongst the lot. (Arthur, 2005) The role of media-ization within the political realm is something that must be judged in the proper light to start with. The citizens of the state must be apprised of their due role within the country and then they must also be told about the different aspects related with the spreading of message through the right channels. Politics must make citizens stand up and act. They should take notice of what is happening around them and what the different regimes and movements are doing for their own betterment. This means that awareness and a sense of knowing needs to be the buzzword when we explore the true meaning of politics and media the same gives the whole discussion a real boost in the related scheme of things. Political media-ization aims to look at the positive sides of delivering quality to the end consumers, for whom the politics is being done. The society is the eventual recipient hence it is the duty of the society to find out what is happening around it. (Newhagen, 1999) The people are a part of this society and they are rightly the winners and/or losers at the end of the day. They must be made aware of the happenings around them when it comes to true political movements, activities, situations and the like. The usage of banners, websites, rallies, advertorials, email and text messages, web portals, newspapers, magazines and even television and radio suggest that political media-ization could be a real happening thing in the times much like today.

'In today's Britain, people vote less on who they are than on what Essay

'In today's Britain, people vote less on who they are than on what they percieve.' Evaluate this statement - Essay Example These two eras as classified are: the time period between 1945-1970, which is signified by a stability in all forms of electoral decisions; while the second era being from 1970 till date, which can be described as the era of decreasingly less identification on the part of voters with any fixed political parties. With increasingly complex behaviour of the voting patterns that were being observed in the contemporary general elections both in UK and worldwide, psephologists came up new voting models that also quite often involved statistical calculations to explain voting behaviours and patterns, and in 1990 we find that W. I. Miller propounding that voting behaviours could be easily differentiated into 6 main models. In my article I will study the shift in the UK voters’ attitude and the perceived changes in the voting patterns, by analysing the various elections that has been held in the recent times and studying the different voting models and political dealignment in British politics.  It will also analyse as to whether strong leadership within party politics does reflect in the vote results, and  if policies of the political parties play an effect in influencing the voting patterns. ... These two parties had strong ideological differences that characterised and became their symbols they stood for, and people voted according to this ideological symbolisation. As for example, the labour party believed in â€Å"high taxation, redistribution of income and wealth, a welfare state characterised by universal public services and benefits, and nationalisation of the country’s major industries[that is, a socialist state]... [While] their opponents believed in the free market in which the state played a regulatory role, with some public services and benefits for those unable to provide for themselves.†2 Thus, the Labour party’s supporters were mainly drawn from the working class level, while the Conservatives’ had their staunch supporters in the non working classes; with some support from the rural sections. The equation was very simple, with the election results depending on how much the two parties were able to get together their own staunch suppo rters while also persuading the voters that were not committed to any parties (these were labelled as the ‘floating voters’) to vote for them instead of their opponent party. This was especially seen in 1945, when a large number of the voters turned over to the Labour party, as the Conservatives were connected with the depression of the 1930s, and the voters en masse thought that giving the socialist Labour party a chance might work out things better for the general populace. In the next elections that took place (1951) we find that Conservatives took away a major share of the voters, as people found that the Labour party had become a little complacent. From this picture it is very evident that

Finding G Using Simple Pendulum Experiment

Finding G Using Simple Pendulum Experiment Abstract This report shows how to find an approximate of ‘g’ using the simple pendulum experiment. There are many variables we could see into, some of them are displacement, angle, damping, mass of the bob and more. However the most interesting variable is, the length of the swinging pendulum. The relationship between the length and the time for one swing (the period) has been researched for many years, and has allowed the famous physicists like Isaac Newton and Galileo Galilei to get an accurate value for the gravitational acceleration ‘g’. In this report, we will replicate their experiment, and will find an accurate value for ‘g’. Finally it will be compared with the commonly accepted value of 9.806 m/s2 .

Equation 1 shows that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: With T the period in seconds, l the length in metres and g the gravitational acceleration in m/s2. Our raw data should give us a square-root relationship between the period and the length. Furthermore, to find an accurate value for ‘g’, we will also graph T2 versus the length (l) of the pendulum. This way, we will be able to obtain a straight-line graph, with a gradient equal to 4Ï€2g-1 . Equipment and Method For this investigation, limited resources like, clamps, stands, a metre ruler, a stopwatch, a metal ball (bob), and some string were used. The experimental set-up was equal to the diagram, shown in figure 1. In this investigation, the length of the pendulum was varied (our independent variable) to observe a change in the period (our dependent variable). In order to reduce possible random errors in the time measurements, we repeated the measurement of the period three times for each of the ten lengths. We also measured the time for ten successive swings to further reduce the errors. The length of our original pendulum was set at 100 cm and for each of the following measurements, we reduced the length by 10 cm. Figure 1 As stated earlier, it was decided to measure the time for ten complete swings, in order to reduce the random errors. These measurements would be repeated two more times, and in total ten successive lengths were used, starting from one metre, and decreasing by 10 cm for each following measurement. A metre ruler was used to determine the length of the string. One added difficulty in determining the length of the pendulum was the relative big uncertainty in finding the exact length, since the metal bob added less than a centimeter to our string length, measured from the bob’s centre. This resulted in an uncertainty in length that was higher than one would normally expect. The table clamp was used to secure the position of the tripod stand, while the pendulum was swinging. After the required measurements, one experiment was carried out to find the degree of damping in our set-up. Damping always occurs when there is friction, but exactly how significant the degree of damping in our experimental set-up was, remained uncertain. Depending on the degree of damping, it may or may not have a significant effect on our measurements. All measurements were taken under the same conditions, using the same metal bob, the same ruler, in the same room, and at approximately 26 degrees Celsius. Data Collected Table 1 In table 1 the  ±o.46 sec uncertainty in time was obtained by comparing the spread for the different measurements. The time measurement for the 0.50 metre length, had the largest spread ( ±0.4 seconds), and was therefore used as the uncertainty in the time measurement. In table 1 the theoretical uncertainty in the length measurement would be 0.05 cm (a metre ruler was used). However, in the experimental set-up, the two end points (the one tied to the clamp, and the one tied to the metal bob) gave rise to a bigger uncertainty, as the exact end-points could not be precisely determined. We estimated the uncertainty in length to be 0.5 cm, or 0.005 metres. These data in table 1 need to be processed, before we can continue our analysis. First of all, the average of the three trials need to be found, which will reduce our error. Secondly, the time for one swing (or one period) must be found, which will reduce our absolute error, but not our percentage error. It should also be noted, that for all the measurements, a constant, and small, angle of maximum displacement (amplitude) was used. The angle was kept between 5 ° to 7 °, small enough to ignore the friction present in our experimental set-up. Apart from these measurements, one more experiment was done to see how much damping was present in our set-up. It took, on average, between 100 and 150 swings, before the motion had seemed to stop. This showed that there was damping present, but this did not significantly affect the measurement of just ten swings. Table 2 shows the processed data and the uncertainties. While drawing the graph for the data in table 2, the relationship between the variables used is clearly not a linear one. The suggested square-root relationship shows it, and to linearise this curve, it must be interchanged and the axis must be modified. (the graph is shown in Graph 1) Table 3 Based on the theory of Simple Harmonic Motion and equation 1, it should be a linear relationship between T2 and Length. When graphing these two modified variables, the regression line must be linear, passing through point (0,0) and with a gradient equal, or close to 4Ï€2g-1 . Graph 2 Conclusion and Evaluation Graphing the length against T2 clearly shows a linear relationship, in agreement with the theory. The actual line of best fit does not go through (0,0) which suggests a systematic error in our experiment. But when graphing a line of best fit, with the condition it should pass through (0,0), we find a line with a gradient of 4.128 and a correlation coefficient of 0.993, which further suggests a very strong linear correlation between our chosen variables. The value for ‘g’ can be calculated by dividing 4Ï€2 with the gradient of the line of best fit; The uncertainty in this value was found, by taking half the difference of the lowest possible value for ‘g’ and the highest possible value for ‘g’: Comparing our calculated value for the gravitational acceleration ‘g’ with the accepted theoretical value gives us an error of 2.5%, well within the error margins that we calculated. This is a reasonable result, given the equipment and the time constraints that we faced. Looking at our graph, we cannot identify any outliers. However, our data values suggest a line of best fit that does not pass through (0,0). When we do fit a linear regression onto our data values, that passes (0,0), we see that the line does not ‘hit’ all the horizontal error bars (the uncertainty in the length). This may suggest a systematic error in the measurement of the length of our pendulum. Further Improvements To reduce the systematic error in the length measurements, one should take accurate measurements of the diameter of the metal bob used. In this experiment, it looks as if we systematically used a length for the pendulum that was too short. If 1 cm was added to our data, we would get a value for ‘g’ that is equal to the theoretical value of 9.806 m/s2 . The theoretical value used, is the average value for ‘g’ on Earth, and may be slightly different from the one that was measured. Instead of three measurements, taking five measurements would be better, as it would not take too much extra time, and this would further reduce our uncertainty in the measurement of the period of swing. Alternatively, measuring the time for 20 swings, instead of 10 swings, would also reduce the uncertainty in time. Lastly, a photogate could be used in the future, to measure the period with higher precision. A nice extension to this experiment would be the use of different metal bobs, of different diameter and/or mass. This would allow us to calculate the effect of air resistance on this experiment.

What Is Orientalism? Essay -- Definition Oriental Orientalism Essays

What Is Orientalism? Said made a clear analogy between orientalism and colonialism. They are both set with the same binary opposition. white/ non white occidental/ non occidental In a very detailed and structured study of the orient (behavior, habit, tradition ...) we document a large amount of fact and data. All compile in a general study they produce the illusion of a well understood and objectively constructed knowledge. These are, in fact, mere observations and purely subjective entities (seen only with the western eyes) which do not explain nor reflect the true nature of the object. We then generalize from theses singles observations, set up categories and labels. We are now able to answer questions very simply creating this illusion of knowledge. We witness the realization of cliches; single sided beliefs that fuels themselves upon their own ignorance. SAID then explains how this technique empowers his creator. The rigorous discourse, the elaboration of thought and ideas, subjectively authenticated itself. The content is no longer address and leaves the victim of the discourse reduced to plain and pure denial. The content has become a set of prejudicial belief (cliches). To remind you of the famous aphorism: "the pen is mightier than the sword" He writes: "Orientalism is fundamentally a political doctrine willed over the orient because the orient was weaker than the west." Though injustice has already been served and the...

Personal Narrative Essay on my first car Essay

There was always one major thought, the goal, a simple dream that made twinges of excitement flow through my body. The waiting was incredible, and it always seemed forever and a day before it would come true. This is a typical pre-teen, adolescent dream, yet it was as important to me as the sun rising. Nothing would ever top this, once I had it, no one could take it away. Getting my driver’s license was only half the battle; the dream was to have my very own car. I wanted it and I dreamed about it everyday. In my early years of high school, my older friends would drive me to and from school, just the normal everyday activities. Usually we would go grab a bite to eat, drop off some of the other passengers–mine was the third stop. Since I was too young to participate in all the activities on their agendas, I was unable to tag along. I had rules and an over-protective mom who was strict on what time I was to return home (and made sure I completed my homework before allowing me to go out with my friends). As the time passed, and I was a bit older, all my close friends started to get their driver’s licenses and living the freedoms that I still yearned. They were able to come and go as they pleased without the hassles of ‘bumming a ride’. With their own transportation many were able to have more ‘choice’ jobs. My time for this accomplishment was nearing. That coming summer I was able to take my driver’s training courses. I was thrilled to no end knowing how close I was to achieving the same sovereignty as my peers. I had two courses to complete that I was raring to get done. With the pressures of high school and all the responsibilities that come along, it was not easy to find a job without my own car. After a couple months or searching for work, I put on my brave front and sought employment (at the ever-so dreaded) mall. I soon found a quaint job and began my quest to save money. It seemed no matter how much I worked, nor how much I was  able to sock away, small bills and responsibilities continued to get in the way. I often thought, † All this money I am giving my friends for gas, I could be putting away, or spending on gas of my own!† Spending a mere five dollars per day alone, expenses were adding up quickly. Although I had small expenditures, I was still able to save here and there, and just prayed I would b e rewarded with lots of monetary units when I graduated. After all my courses and many hours of driving with my mother and friends of age, I was ready for my road test. I was overly prepared, and knew I would ace this test. Without a second thought, I hit the ground running; my parallel parking was flawless, speed limit was on target, and my hands on nine and twelve as they should be (many may remember the old version on ten and two). Soon enough I was at the local Secretary of State, dressed up, more nervous about the picture then I was about the test itself. Within a few weeks, my small hard plastic license was in the mail. Only one problem remained, I had no vessel for traveling! I had my license for nearly a year when my senior year was coming close to an end. I had a small amount of money saved and was depending heavily on graduation money to satisfy my thoughts and needs for buying a car. I had my sights set one car. It was within my price range, and met every one of my demands. The car was a 1985 Mercury Grand Marquis, crà ¨me colored (the year is now 2001). Matching Beige interior, working quartz clock, dual exhaust cherry bomb mufflers (loud enough to set off a car alarm) complete with a CD player. I am not the type of girl who wants a brand new car. Mine had to be already loved; and then hated enough to sell. A car that has it’s own distinguished smells of adventure. One that no longer has the owner’s manual, so you find out new appurtenances about the inner-workings and excites you to the point where you show the ‘new’ features to all your comrades. The first time you clean it out, you may find treasures under the seats and in the nooks and crannies. It needs a little more love than the rest so it will run nice and warm in the winter, and will not over heat in the summer. A place where you can listen to any of your CD collection and it  sounds amazing (just because it is all yours). A car that can fit five or more people in , for those surprise trips that you cannot refuse. That was the perfect car for me. One that you can give a divine name to, like Maurice. Within a few months of graduating, the Grand Marquis was put up for sale. A gleaming reddish orange â€Å"FOR SALE† sign hung proudly in the rear window, and it read in large, black letters $900! I could not believe they were going to let such a treasure car go for so little money! It was all I could do to contain myself knowing I had just enough money to buy it, and still have some left over to get it washed and buy a few things to personalize the interior. Seeing as how it was a friend’s vehicle, I was first in line for bids. After a few days of negotiations (and me being a long time friend of the entire family) they let that beauty go for a measly $500! There were tasks to be completed before I was able to show my very first car off. I purchased a new furry steering wheel cover with a matching pillows in the back that stated â€Å"BLING $$ BLING† in gold glitter, a super heavy duty car wash, a misting of Febreeze, a good wipe down of the interior, and I was ready to gloat. I raced up onto my front lawn, careful to not mutilate the grass or murder the daisies, and laid on the harmonic horn until the whole household was outside to witness the cars majesty. I had put on the perfect track of everyone’s listening pleasure, The Joker by The Steve Miller Band. â€Å"Some people call me the space cowboy, yeah, some call me the gangster of love, some people call me Maurice†¦Ã¢â‚¬  It was awesome! A pubescent dream, whether big or small is important to one’s self image or self-confidence. I could not imagine living in a world without dreams or aspirations, whether they are material objects or transcendental hopes. To some, a dream of a car seems inconsequential; to others it’s their whole world. This was all I ever wanted in an automobile, just enough to transport me to my destinations and acquiesce in me the carte blanche that I had always dreamt about.

Play Review on West Side Story essays

Play Review on West Side Story essays Drama Play Review on The musical Play that I did my review on was West Side Story by Jerome Robbins. I saw this play at the Woodland High School with my family. We went to see it because my older brother, Nick was in it. Thinking about the overall production, I liked that it was about two gangs fighting over their turf as they called it. It was cool because it showed me what simple lives they had but ending up in a tragic ending. I also liked how they seemed to have an accurate perception of what each of the gangs whore and what they acted like. The setting of the background stood for all the scenes and purposes of they play and it was like a real place in a city. I thought that was pretty cool. Thinking about the overall production, I disliked how they had so many singing scenes and that sort of got boring so I wouldnt come back and see it again. I also thought that some of they parts should have been played by the other characters (not naming any names). If I were to do things differently as the director I would have watched the movie and made a better selection who could fit the character better and who would better as a different part in the play. Overall it turned out to be really good but those would have been the changes that I would have made. A character that I did not like was Maria. She did well as the character but she didnt really fit the part. I dont want to be mean but that is just my opinion. Another person that I didnt like was Riff. He seemed to over act a little too much but he still did a good job (better than I could have done) playing the part. A person that I did like was Action. He played a good part because he acted wild and gave me the feeling that he was really that sort of person. He would always go wild when something came up and never calm down except when Tony or Riff order ...

Phase 1 Discussion Board Schedule and Cost Control Techniques Essay

Phase 1 Discussion Board Schedule and Cost Control Techniques - Essay Example After this survey we have to analyze the gathered data from the survey. This analysis sub phase provides all required information for our project seclude and cost estimation. After this analysis sub phase next comes the design sub phase of the project in which we have to design all events and process that are necessary for the completion of this project. In this phase we also demine expected expenditure, estimate time required, and main events of the up gradation project. Then next phase is Executing Phase. Here we hire a software development team for the implementation of this new upgraded email system, now our project team completes the work related to all aspects of this up-gradation. Here an impotent phase is controlling phase that will run in a parallel way with all other phases. In this phase we control the time, cost, manpower required, resources needed and all things that are associated with is project. We analyze all the ways like project is running on time, is any module required additional time, then managing time in such a way that additional time is not required. Cost and expenditure monitoring is done in such a way that no extra resources will be needed along the way. Then the last and final phase would be Closing Phase: here we have to ensure that the project work is complete successfully, we have to confirm and verify that the deliverables and then completed out the project finances, panel reports, and lessons learned are all documented and analyzed that all thing are well and new email system is working properly. Cost estimation is one of main and difficult part of any project (Chamoun, 2006). All project depends on this estimation, if this estimation goes wrong then lot of complexities might occur during the project. So in our Email Up-gradation project we have to estimate the cost in such a way that no complicity can happen, and project can be completed successfully. As a project manger it is my

ETH501, Business Ethics, Mod 2 Session Long Project Essay

ETH501, Business Ethics, Mod 2 Session Long Project - Essay Example It is the company’s duty to inculcate such an environment in the company and practice such ethical behavior that employees have nothing bad to say about the company. Many companies, however, take the easier route, that is they coerce their employees to restrain from whistle blowing about the company. One such contract, where an employee was restrained from speaking anything bad about the company was offered Charles F. Frenette. The contract stated that the initial offer to him about a stock option will e forfeited if he is found disparaging or using bad words about the company. This was like stopping him from speaking what he wants or what he may want to speak in the future. And punishment levied on him for his freedom of expression would be forfeiting his monetary reward. As discussed before, you cannot force an employee to restrain from speaking and instead you should inculcate such policies with the company that it may never indulge in any wrongdoings and hence does not come under bad wording by its employees. Let’s now look at the issue under the two most important ethical frameworks of deontology and utilitarianism. Unitarianism is all about the good for the society. This principle states that every action should increase the goodness for the society in all cases. An action should only be taken if costs associated are less than the benefits attained from it. For example, if Coke’s decision to stop its employees from whistle blowing or from telling people about any wrong doing of the company, this action would bring upon people very negative effects and will save only the reputation of the company. In other words, the costs inflicted in the society might be very high as compared to the reputation of the Coca-Cola that will be protected from any controversy. Under this ethical framework, the clause added by the Coca-Cola Company is never justified. They are inflicting costs on the

Rationalism vs. Empiricism Essay Example | Topics and Well Written Essays - 750 words

Rationalism vs. Empiricism - Essay Example . Contrary to empiricists, rationalists embrace deduction. This means being able to prove something by relying on certainty and not reason. For instance, Descartes relied on deductive reasoning as a way of proving God’s existence. Conversely, empiricism denotes a belief in the sense perception as the source of knowledge. For example, John Locke explained this belief by dividing sense perception into two parts that include simple and complex ideas. The simple ideas emerge from only on perception. This may include for example, perception of color or size. On the other hand, complex ideas are derived by combining the simple ideas (Alexander 58). Further, another belief that separates empiricism from rationalism involves the acquisition of ideas through experience. In essence, ideas according to empiricists, are not acquired through an innate process. Empiricism does not embrace innate ideas in the sense that, knowledge varies. For instance, a child’s mind is a tabula rasa, but learns from experience. In essence, if they possess the knowledge, they should use it from the start. According to Lock, simple ideas emanate from experience, and those ideas are combined to form complex ideas. In addition, empiricism contrary to rationalism endorse a belief in induction. This is the belief that only a few phenomenon are proven conclusively. For example, people identify things through their sense perception. However, most perceptions cannot be concluded to agree with the objects being perceived (Alexander 65).

Improvement of standard living contributes to damage to environment Essay Example for Free

Improvement of standard living contributes to damage to environment Essay In the last decade, many countries over the world have to experience the inevitable consequences of damage to environment. The environment has been sacrificed as the people’s standard living has been improved, which is including the rising of new technology. Sometimes, the new technology that has been invented can cause environment’s devastation enhancement and also harms the ecosystem on it. Many forests and parks have disappeared so that animal extinction for some species cannot be avoided. Nowadays, many developer company compete each other to build residences, apartments, hotels, malls, entertainment centers, such as cafes, cinemas as the enhancement of our standard living. People need a living place more than just a place to sleep and take a rest. The more facilities that one residence area or apartment has, such as swimming pool, golf area, gym, supermarket; the more benefit they can offer to attract customer. It means, one developer company needs bigger areas to construct a residence or apartment. Besides that, we can see the increasing amount of skyscraper buildings in big cities. Along with many constructions, it means that many green areas has to be cut off to be changed into a commercial area and people do not contemplate the consequences of not having enough trees and green areas. In addition to this, many constructions also are not built with a good drainage system. Due to this matter, flood happens everywhere. For instance, in Jakarta, Indonesia, flood happens at least once per year during peak rainy season as the result of constructing park and forest to be a commercial building. Industrial companies also contribute to environment’s devastation. High technology system is developed to support the industrial business. Some of new technology system that has been invented are not eco-friendly. For instance, in Agriculture industry, pesticide is used for controlling the pest that can harm the plant. The consequences of using pesticide that can contaminate the soil, the plants, and harm the ecosystem surrounding it are being ignored and also it can harm the people who consume the fruits or vegetables of those plants. In addition to this, many wastes are produced every year and most of the waste cannot be recycled. Some of the waste fills the river and harm the ecosystem that live in the river, such as fishes. Later on, consuming fish from contaminated river can jeopardize human’s health. In the end, we have to realize that along with standard living improvement, often we neglect our environment and abandon the balancing of ecosystem in our planet. Besides environment devastation, we also harm our lives and our next generation lives. It is suppose that now is the perfect time for us as human being to look after our planet; maintain, protect and nourish our environment surrounding us to build a better health life in the future.

Instruments Of The Orchestra :: essays research papers

Instruments of the Orchestra Strings: The viola is an important member of the orchestra, but is not often heard by itself. Because it is bigger than the violin, with longer strings, it makes a rich, warm sound that is lower in pitch. In contrast to the viola the violin is the smallest member of the string family. Because its strings are the shortest, it produces the highest sound. The viola is a little heavier, and its shape is slightly different, too. But it is still played on the violist’s left arm, just like the violin. Unlike the viola, the violins play in two different groups: with the first violins playing the highest-pitched part and the second violins playing the second highest. Both the viola and the violin are placed to rest on one shoulder, and held in its place by the chin and the left hand. You have to hold the bow in your right hand, and draw it across the strings. Pitches can be change in two ways: by drawing the bow across different strings, and by pressing on the strings with the fingers of his left hand. The viola plays a beautiful â€Å"middle† part in the orchestra’s harmony. The violas can be hard to pick out when the whole orchestra is playing, but you would really miss the violas if they weren’t there! In the other hand the violin has stayed pretty much the same ever since the 1500s. That’s almost 500 years! The modern violin has four strings, but the earliest ones had only three. Fiddlers played them on the streets, which hoped that people passing by would like their tunes and toss them a few pennies.   Ã‚  Ã‚  Ã‚  Ã‚  Viola  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Violin Woodwinds: The bassoon is a double-reed woodwind instrument. It has almost 8 feet of wooden tubing, bent into a narrow U-shape. The reed is secured in a curved metal tube. Bassoons are the largest woodwind instruments in the orchestra - except for the contrabassoons, which are much bigger and plays a whole octave, lower than the bassoon! In contrast to the bassoon, you can hear the smooth, velvety sound of the clarinet in the orchestras, military bands, and in jazz groups. Clarinets are made of wood or molded plastic, and can be found in the different range of notes. The standard â€Å"B-flat† clarinet is a little more than two feet long. An orchestra also often includes an â€Å"E-flat† clarinet, which is smaller and plays a higher range of notes, and a bass clarinet, which plays an octave lower.

Evaluate Is Acceptance Model Essay

There are many models have been developed to understand the factors affecting the acceptance of computer technology such as Theory of Reasoned Action (TRA) (Fishbein & Ajzen, 1975, Ajzen & Fishbein, 1980), Theory of Planned Behavior (TPB) (Ajzen, 1985, 1991), Technology Acceptance Model (TAM) (Davis, 1989), Decomposed Theory of Planned Behavior (DTPB) (Taylor & Todd, 1995), and Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh et al., 2003). TRA proposes that individual beliefs influence attitudes which will create intentions that will generate behavior. There are two major factors that determine behavioral intentions which are the person’s attitude toward the behavior and subjective norms. Attitude toward the behavior refers to the person’s judgment that performing the behavior is good or bad according to his or her belief. While the subjective norms are a function of normative beliefs that reflect the person’s perception of social pressures put on him or her to perform or not to perform the behavior in question. TRA model TPB is an expansion of the TRA. TPB includes the construct, perceived behavioral control to measure and account for the extent to which users have complete controls over their behavior. Perceived behavioral control relates to the extent to which the person believes that she or he has control over personal or external factors that may facilitate or constrain the behavioral performance. TPB model TAM pioneered by Davis advances the TRA by postulating that perceived usefulness (PU) and perceived ease of use (PEU) are key determinants that lead to the actual usage of a particular technology or system. Perceived usefulness is the degree to which an individual believes that using a particular system would enhance his or her productivity while perceived ease of use is the degree an individual believes that using a particular system would be free of effort. TAM model DTPB was formulated through combination of both TAM and TPB, which was intended for providing better understanding of behavioral intention by concentrating on the factors that are likely to impact systems use. This model explores dimensions of subjective norms and perceived behavior control through decomposing them into particular belief perception whilst constructs from the innovation characteristics has also been regarded as the basis of DTPM formulation. DTPB also offer a clearer understanding of behavior and behavioral intention by giving detailed information about impacts of normative and control beliefs over system usage. DTPM model UTAUT had synthesized the eight prominent user acceptance models including the TRA, TAM, the motivational model (MM), TPB, a model combining the technology acceptance model and the theory of planned behavior (C-TAM-TPB), the model of PC utilization (MPCU) (Ronald et al., 1994; Thompson & Higgins, 1991), the innovation diffusion theory, and the social cognitive theory (SCT) (Compeau et al., 1999 and Compeau & Higgins, 1995). This model was formulated with four core determinants of intention and usage including performance expectancy, effort expectancy, and social influence and facilitating conditions and also with up to four moderators of key counting gender, experience, age and voluntariness of use. However, the authors argue that in order to strengthen this model, the culture also need to take consideration since different culture can affect the acceptance behavior among user towards the computer technology. UTAUT model There are more theories that had been developed and many variables had used to evaluate the IS/IT acceptance rate. For example, the interactive model of technology acceptance and satisfaction (IMTAS) which integrate the user satisfaction with and user acceptance of IT. This model expands user satisfaction and user acceptance into SME sector simultaneously as two basic constructs of system usage behavior (as the key measure of IT success) while addresses specific characteristics of SMEs such as resource constraints, management method and direct interaction of SME users with external environments. Base on this model, user satisfaction can be influenced by user involvement, system quality, and information quality. High quality of information and system enable the user to produce good decision making, hence, increase the user satisfaction. However, user involvement is the key determinant of user satisfaction since high user involvement allow the user  involve in major area of the system which this give the user opportunity to enjoy most of the benefits of the system. User satisfaction will increase the usage of the system and the usage will be even higher if the system has high user friendliness. Another key determinant that influence the system usage in SMEs is user computer competence. User computer competence can be enhance through providing training by assuming that assistance of SMEs’ external environment have a crucial impact on the success of newly implemented IS by increasing SME user acceptance and satisfaction since SMEs are typically suffering from lack of resources such as internal expertise, knowledge and user skills. The training can influence the perceived ease of use and perceived of usefulness among user, hence, influence the user attitude and intention which than influence the actual usage of a system in SMEs.

Mixed Schools Is the Optimum

Mixed Schools is the optimum Coeducation or mixed-gender education is the integrated education of male and female students in the same environment, while unisex education is the education where male and female students attend in separate classes or in separate buildings or schools. In the past, mixed schools were not acceptable, but by the time it became popular. Mixed schools are better for students socially, and it also develops their educational skills and psychological things.Parents recommend mixed schools because it develops many skills for the kids. Mixed schools make students get used to the social life. Supporters of the unisex schools believe that the school is not a place for developing your social life skills, but just for studying. Also, some parents do not want their children to be in mixed school because at certain ages, students of the opposite sex can be a distraction. However, the best place that helps children to get ready for the real social life is the school. St udents in single-sex classrooms will one day live and work side-by-side with members of the opposite sex. Educating students in single-sex schools limits their opportunity to work cooperatively and co-exist successfully with members of the opposite sex† (Stanberry, 2009). It's so important to have friends from both sides of the fence. â€Å"You would never find a workplace with only females, so this prepares you for the outside world much better† (Davidson, 2003).According to the Education International, statistics indicated that mixed schools students have recorded the highest success rate. People who believe that unisex schools are the best say that mixed schools distract students’ attention. On the other hand, the researchers conducted extensive interviews with individual students and found excellent students do not get distracted.
