Television Censorship Essay -- essays research papers

Television Censorship WHAT IS CENSORSHIP? "Censorship is the supervision and control of the information and ideas that are circulated among the people within a society. In modern times, censorship refers to the examination of books, periodicals, plays, films, television and radio programs, news reports, and other communication media for the purpose of altering or suppressing parts thought to be objectionable or offensive. The objectionable material may be considered immoral or obscene, heretical or blasphemous, seditious or treasonable, or injurious to the national security. Thus, the rationale for censorship is that it is necessary for the protection of three basic social institutions: the family, the church, and the state. Censorship and the ideology supporting it go back to ancient times. Every society has had customs, taboos, or laws by which speech, play, dress, religious observance, and sexual expression were regulated(Microsoft Encarta 95)." CENSORSHIP OF OBSCENITY "The beginning of a new legal approach may be traced to the action of the federal courts in the 1930s, when they held that Irish author James Joyce's Ulysses was not obscene and could be freely passed through customs. The courts ruled that the use of "dirty words" in "a sincere and honest book" did not make the book "dirty." Since the 1950s many obscenity cases involving books, magazines, and film have been brought before the Supreme Court. In the cases during the 1970s the court ruled that laws against obscenity must be limited " to works which, taken as a whole, appeal to the prurient interest in sex; which portray sexual conduct in a patently offensive way; and which, taken as a whole, do not have serious literary, artistic, political, or scientific value." The Court has further held that obscenity should be determined by applying "contemporary community standards" rather than national standards (Microsoft Encarta 95)." WHO DOES TELEVISION CENSORSHIP EFFECT? CENSORSHIP AFFECTS MINORS AND ADULTS Does censorship affect both minors and adults? One incident in Ohio led a mother of a 5 year old boy to believe so. The boy's mother attributed his actions to the influence of the popular MTV cartoon show Beavis and Butthead. In response to watching this cartoon the boy set his house on fir... ...censorship of television. The government of the United States of America has been getting very involved in what they think is appropriate to be on television. I want to know why they get to decide what I want to watch. I feel that it should be a person's choice. They say they are concerned with what children are viewing, or that some things such as nudity and swear words offend people. Parents should monitor what their children watch. If a parent does not want their child to see something in particular, then it is the parent's responsibility to see that they do not, not the government's (Microsoft Internet Explorer)." What do you think? Should our government continue to enforce television and film censorship as it has been? Or should all forms of censorship be abolished completely? THE PURPOSE "It is the purpose of this Act to increase competition in all telecommunications markets and provide for an orderly transition from regulated markets to competitive and deregulated telecommunications markets consistent with the public interest, convenience, and necessity (Telecommunications Bill of 1995, Internet)."

Samsung Electronics Strategic Analysis

One of the point to make the success of Samsung is its managers interested in long-term growth rather than short-term profit. .Strategic thinking of the Samsung Group is focused on developing target market and making a huge bet on them. That ‘s the reason we don’t mention the short-term stratgy of Samsung bacause it isn’t the main point of Samsung;strategy and we can learn just a little thing from it. Come back to the long-term strategy of Samsung, we can devide it to 2 periods.Before the lawsuit with Apple Unlike other Android phone makers, Samsung chose a very different way which is competing head-to-head with Apple in the high-end smartphone segment, by creating products that have a similar design to the iPhone but do not forget to â€Å"put effort† for the low-range smartphone in order to control market share and create great motivation for the Galaxy’s brand na me. While its competitors like Apple concentrated on creating new innovative products, Samsung waited their competitors test the market and then they determine the most suitable time to break into.It created the similar smartphones with those of other companies but better, faster and cheaper. When taking part in , Samsung will dominate the market with a series of models with various improvements that competitors can not keep up . This strategy has an interesting name in Vietnam :â€Å"di t? t, don d? u†. With this strategy, Samsung has many advantages when it has known the strengths or the wickness points to make the success and failure of its competitors.So it can decrese the risk when taking part in the market. After the lawsuit with Apple After having created a buzz in the market, Samsung started to follow their own direction that the Galaxy S III is the most typical example. No one can complain about the copyrihts when they compared the Galaxy S III to the iPhone 4S or iP hone 5. With products like the Galaxy S III or Galaxy Note, no one dared to say that Samsung copies competitors, they just rely on its opponents to make innovative products.

Converting Microliters to Milliliters

The method to convert microliters (ÃŽ ¼L) to milliliters (mL) is demonstrated in this worked example problem. Problem Express 6.2 x 104 microliters in milliliters. Solution 1 ÃŽ ¼L 10-6 L 1 mL 10-3 L Set up the conversion to the desired unit will be canceled out. In this case, we want mL to be the remaining unit. Volume in mL (Volume in ÃŽ ¼L) x (10-6 L/1 ÃŽ ¼L) x (1 mL/10-3 L) Volume in mL (6.2 x 104 ÃŽ ¼L) x (10-6 L/1 ÃŽ ¼L) x (1 mL/10-3 L) Volume in mL (6.2 x 104 ÃŽ ¼L) x (10-6/10-3 mL/ÃŽ ¼L) Volume in mL (6.2 x 104 ÃŽ ¼L) x (10-3 mL/ÃŽ ¼L) Volume in mL 6.2 x 101 ÃŽ ¼L or 62 mL Answer 6.2 x 104 ÃŽ ¼L 62 mL
