The Spread of Television in 1950s, in America Essay -- Television

The ‘Golden Age of Television’ is what many refer to as the period between the 1950s and 60s when the television began to establish itself as a prevalent medium in the United States. In 1947, the American Broadcasting Company (ABC), Columbia Broadcasting System (CBS), the National Broadcasting Company (NBC), and the Du Mont Network were the four main television networks that ran stations with regular programming taking place. (Television, 2003) While regular television programming was a new innovation, the television itself had been commercially available for over twenty years prior to the 50s. It was conceived by many worldly innovators and went through several testing stages before it was finally completed in the late twenties. The three main innovators were Niplow - who first developed a rotating disk with small holes arranged in a spiral pattern in 1884, Zworykin - who developed the Iconoscope which could scan pictures and break them into electronic signals (a primi tive form of the Cathode Ray Tube) in 1923, and lastly Fansworth - who demonstrated for the first time that it was possible to transmit an electrical image in 1927. (Rollo, 2011) However, one of the many reasons why this medium was successful in the 50s was due to the fact that it became more accessible to the public. Television sets were more affordable to middle class citizens which created further interest in the new technology. Through an historical account of the medium, the spread of television across America throughout this particular decade will be examined. Firstly, for the purposes of illustrating the cultural context of this decade, I will refer to Lynn Spigel’s writing entitled â€Å"Welcome to the Dreamhouse: Popular Media and Postwar Suburb†.

Banning whaling

Whales are the biggest animals that live on this planet, in the oceans. Depending on their species they can weigh up to 200 tons, the weight of around 12 elephants or 2000 people. It has also been studied that the brains of whales are developed which means they are intelligent creatures. Since centuries whales have been hunted down for their oil and meat. The process of killing whales for their meat and oil is called whaling. In the olden days only the slow moving whales were hunted.By the 17th entury the demand for whale 011 and meat rose and It wasnt until the 18th century when a new hunting weapon was invented. Since harpoons were invented, fast paced whales like blue whales could be killed but it is a very cruel way of hunting whales. Whales being the biggest animals of our planet and being driven to almost extinction, It becomes our duty to ban hunting whales and preserve them. Commercial whaling has driven so many whale species to near extinction. Not only that but other factor s like ocean noise, pollution, climate changes also threaten their existence.In 1 905, since whaler shifted to Antarctic waters, South Georgia became he Centre for whaling and between 1930-1931 30,000 blue whales were killed and processed 1 That nearly drove the blue whales Into extinction as they were hardly noticed ever Lohan 2 since. In 1986 the International Whaling Commission banned whaling all over the world to protect whales from being hunted but despite that, many countries still practice whaling either In disguise of research or to maintain the Industrial demand for whale meat and oil. Countries that still practice whaling are Japan, Iceland, Norway.Iceland has recently alone killed hundreds of whales and send tons of hale-meat to Japan whose market Is already so full of whale meat. In Japan whale meat Is a delicacy and on the pretext of scientific research It kills whales. Whales take time to mature and also reproduce slowly. They only have one young one in around 3 years and it takes time for a specie to recover after being hunted in masses. Hence its numbers decrease to extinction so easily that we don't realize the harm we do by killing whales that are so Important to our ecosystem.People all over the world consider commercial whaling to be cruel. Nowadays people all around the world love whales and whale watching trips have become opular. Many see whale watching as a better alternative to whale hunting -It Is a 1 OF3 whales popular amongst people2. â€Å"In the late 1980s, whale watching became popular outside the Ogasawara islands south east of Tokyo where they claim to have a 90% success rates for watching humpback whales by boats during the past few years. † Whale watching trips are offered there everyday at times for 2 hours or 6 hours.The types of Lohan 3 boats are diving boats, pleasure boats and commercial/sports fishing boats3. Humpback whales and right whales are making a comeback in their numbers due to protection organizations. This, being a success, shows that we should hold out more protection campaign for whales because many species are still fragile and cannot recover their numbers quickly. Many people consider that the method of killing whales is extremely cruel. â€Å"Although whaling fleets may be highly sophisticated, equipped with sonar, helicopters, long-range explosive harpoons and factory ships, the actual kill is horrific† 4.The way a whale is killed is through a harpoon, which is 90 kilograms in weight and is shot from a cannon. The head of the harpoon has a time fused grenade which when hits the whale, explodes and tears the internals of the hale apart. The whale still continues to suffer until hours of beating when it actually dies. Whales are smart creatures and it is not possible to find a humane way of killing them. People say killing whales is good because whales eat a lot of fish but what we don't realize is over-fishing is a bigger factor for decrease in fishes.Since whales hav e decreased in numbers fishes should have increased in their numbers but they haven't, hence we are only to blame for the diminishing of aquatic animals. Japan has killed hundred of whales even after the ban on whaling. They kill whales on the rounds of scientific research whereby when a whale is killed scientists recover parts of the whale, which helps them understand the age of the whale, its diet, Lohan 4 and birthing rate and the meat is packaged and sold in the market5.Japan's history has shown that it largely depends on whale meat for its source of protein and nutrition and thus still kills whales for food. â€Å"NRDC and over a dozen other conservation groups recently petitioned the Obama administration to take strong action against Iceland under the Pelly Amendment to the Fisherman's Protective Act† 6. Through this, the President can impose trade sanctions to a country that does not obey conservation agreements. The United States has been a leading global conservator for whaling.To sum everything up, Whales have been hunted for years to such an extent that many species of whales have been driven to extinction and it takes time for a specie to recover its numbers because of the slow rate of whale reproduction and maturity. It is more profitable to have whale watching than killing whales because whale watching serves as a source of income through tourism. Whale oil used to be in demand in the olden days but due to modernization and lternatives for whale oil , the profits from whaling has decreased because now a days whale oil is rarely used.The methods of killing whales are inhumane as they are When shot, they may take up to an hour to die but in the meantime suffer. Countries still practice whaling either through pretext of scientific research or commercial whaling. Consumptions of whale meat Lohan 5 can be harmful because the mercury content in them was found to be high as studied in Japan. Whales are significant to our ecosystem and without the m the marine ecosystem is vastly affected. Whales are magnificent creatures and are espected and loved all around the world.They are intelligent and also the biggest on our planet. Hunting them to extinction is Just another projection of how cruel and inhumane mankind can be. Banning whaling should be maintained all around the world but with stricter impositions.

The Best Way For Reach Children A Mixture Of Progressive...

PHILOSOPHY ESSAY I believe the best way to reach children is through a mixture of progressive teaching along with social reconstruction. Proverbs 22:6 explains the background to my philosophy perfectly, â€Å"Train a child up in the way he should go, even when he is old, he will not depart from it† (New American Standard Version). I think children learn better, when they are interested in the curriculum. Children should do projects that involve their minds so it helps them to remember. I also think that children should be aware of problems in our society and think about how they can change the world for a better place. As a history teacher, I want my students to truly learn history, not just memorize dates. In order to achieve this I will divide the class into groups of four or five students each. Then I will have each group pick a piece of history that they want to study from a selection that the class is going to learn about on American history. I will let the groups choose which event they want to have because students learn better, when they are interested in the subject. According to the textbook Introduction to Teaching, students â€Å"best courses were those that had them work on projects (e.g., science projects) that allowed them to solve problems that were interesting to them or to write about topics that were important to them† (Kauchak Eggen, 2014, p. 157).

What types of problems and effects are been forced upon the planet Free Essays

What types of problems and effects are been forced upon the planet with modern technology and the increasing population and what can be done to make the planet healthier? The growing population, deforestation and use of fossil fuels are causing the biggest environmental problem that has been discovered over the past 50 years, Global Warming. In the past 10 years dramatic actions have been taken to curb the dangerous affects that could lead to drought, floods, sweltering heat and rising seas. I believe that to curb the effects more people should be aware of what the future would be like for future generations. We will write a custom essay sample on What types of problems and effects are been forced upon the planet? or any similar topic only for you Order Now How their lives would be affected by global warming. Simple things like walking to work and school or using a bike to commute would make a huge difference, if more people knew that bicycling is 117% more efficient than walking, and then I believe more people would do it. However the majority will have to take this into account if they want to make a difference. By simply wearing an extra shirt around the house and not turning on the heating will contribute to saving the environment. Paper which is made from trees should not be wasted and recycled when finished with. In order to prevent unnecessary usage of the planets resources’ recycling helps to curb the effects of deforestation. Whenever a person uses a car or forgets to switch their television off at the mains, leaving the little red light to waste energy, a thought should be spared for the millions of men women and children that survive every day in third world countries who have quite possibly never seen a television. If every commuter car in the U.S. transported an extra person, it would save eight billion gallons of fuel a year. Facts like these assist in convincing people that small gestures matter. However many people do not think that just one person can make the difference. Scientists have discovered the main causes of global warming and because of this curbing the effects causing global warming is a great deal easier. Emissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fossil fuel combustion, and changes in land use, such as deforestation all contribute to the increasing temperature of the planet. Heat from the sun passes through the atmosphere of the earth and heats up the earth’s surface. The heat is reflected back out to space by the earth’s surface but certain gases in the atmosphere trap some of the deflected heat. These gases then act as a blanket, keeping heat locked in the atmosphere warming the planet. This process is similar to that which takes place in a greenhouse environment hence the name â€Å"greenhouse effect† and â€Å"greenhouse gases†. Greenhouse gas (es) is the name given to the gases which trap the heat in the earth’s atmosphere. Carbon Dioxide is the greatest contributor to the build up of gases in the atmosphere. Cars, Factories, even using paper all contribute to the hostile planet we are all creating for future generations. Fossil fuels release the majority of harmful gases into the atmosphere, so in order to reduce the amount of dangerous gas entering the atmosphere; other sources of energy are being used. Renewable energy sources such as Solar Power, Wind turbines/farms, Tidal, Hydro-electric, Geothermal and using Biomass and alternative power sources such as nuclear power all contribute to the decrease in use of fossil fuels. Trees provide oxygen for the planet by removing the carbon from carbon dioxide and releasing oxygen back in to the atmosphere. This done by a process called photosynthesis. Transpiration is a process whereby the plants carry water up the stems of the plants into the leaves and it evaporates through the leaves. These processes determine the weather and cause clouds, which block the suns heat from passing through the ozone layer. Deforestation regularly occurs because of farmers attempting to settle farmland; the poor become ‘shifted cultivators’ and resort to using ‘Slash and Burn’ methods to make an open space. The name implies exactly what happens; trees are cut down and the remains are burned. The ash is used as a fertilizer and the land is used for vegetation farming or a cattle farming, however, the soil that is cleared in slash and burn is left infertile; the nutrients in the soil are quickly absorbed by surrounding organisms. The trees can no longer be replanted in the same area once a shifted cultivator is finished in that area. Another reason for major deforestation is because of many labourers resorting to illegally cutting down trees to survive. The UN has however developed a plan to provide the poorer countries with enough money to stop the deforestation. Acts like these will all help to minimise the dangerous effects inflicted on the planet. Tidal barriers attract a lot of controversy. The proposal to build the Severn Barrier has been severely opposed by many environmentalists, because of impacts upon wildlife and the marine environment. The construction of tidal lagoons has been proposed as a more ecologically sound method of generating electricity from tides. However due to global warming, it is inevitable that the sea levels will rise. Coastal cities must be protected against sea level rise, so tidal barriers must be constructed for this purpose. If CO2 emissions are not dramatically reduced within twenty years we will face much greater sea level rise, and we will then have to look at tidal barriers to protect other UK cities, on the River Severn. Although Biomass is a renewable energy source it does release greenhouse gases into the atmosphere reducing the use of fossil fuels but not necessarily reducing the emissions of harmful gases into the atmosphere. Nuclear power is not renewable but it does not emit any harmful greenhouse gases and therefore it does not contributing to the greenhouse effect. At present, there are 442 nuclear power stations in operation in the world, with a generation capacity of 368 million kilowatts, which accounts for 16% of world’s total power generation for 18 consecutive years. Nuclear power has many advantages; it is cheap and produces large amounts of energy from small amount of fuel, it is also very reliable and produces very little waste. Although there is little waste produced, it is dangerous and has to be buried underground to contain the radioactivity; it takes hundreds of years before the radioactivity is gone. On April 25th -26th, 1986 the planet suffered worst nuclear power accident occurred at Chernobyl in the former Soviet Union (now Ukraine). The Chernobyl nuclear power plant had 4 reactors and whilst testing reactor number 4 numerous safety procedures were disregarded. A chain reaction in the reactor became out of control creating explosions and a fireball which blew off the reactor’s heavy steel and concrete lid. The Chernobyl accident killed more than 30 people immediately, and as a result of the high radiation levels in the surrounding 20-mile radius, 135,000 people had to be evacuated. It will take four hundred years before the affected area will become liveable again. In conclusion, I have discussed the effects of pollution and the controversy caused, I have also discussed what can be done to curb the effects. The use of renewable energy can assist in the prevention of further damage, and that walking or bicycling instead of driving can also reduce the damaging effects facing the environment. I have discussed the disaster and consequences of nuclear power and its advantages to the environment. I would like to conclude by saying that unless drastic measures are taken to ensure the safety and wellbeing of future generations, the planet will die and we, as a species, will too.

Biography On Linda Crew (motives For Writing Child Essay Example For Students

Biography On Linda Crew (motives For Writing Child Essay ren Of The River) About Linda Crew and her reasons for writing this The author of Children of the River, Linda Crew, expresses her emotions and brings her past experiences into her writings. A lot of authors base their books on personal experiences; Linda Crew is just an example of one. Linda Crew went to the University of Oregon, since she lived in Oregon for a while before writing Children of the River, which could be a major factor in why it took place in Oregon. She then got married, had children and lived on a farm there. (http://www.randomhouse.com/teachers/authors/crew.html) After all, in the book, Sundara did move to Oregon from Cambodia. So Linda Crew probably liked it in Oregon and wanted the main characters in the book settle there. Speaking of Cambodia, when Linda Crew was in Oregon, her friends were Cambodian refugees who inspired her to write this novel. (Crew, Linda, Children of the River back cover) She probably asked them how it felt to be Cambodian refugees and what their past experiences were and how they dealt with all of their problems. Also, I think this book was about love because at the time when she wrote this book, she was in love and had just gotten married. She knew how it felt to be in love and what happens when you? ¦re in love. She just wrote about her feelings and how good it felt to be in love with the right person, just like how Sundara had to choose between being in love with Chamroeun or Jonathan. Linda Crew chose to write about her experiences, her feelings and her friends. Almost every author, if you look into their past deep enough does that with their novels. All in all, Linda Crew is an outstanding author with excellent novels of great quality. Category: Biographies
