Elements Of Design In A Play Essay Example for Free

Elements Of Design In A Play Essay There are many things which can both attribute and take away from the overall production of a performance or play such as a Shakespeare play. Such things include costumes, props, lighting, set, and sound. All of these factors are vital in the ending effect that the performance has on the viewing audience. Firstly, when attending a play, their are several things that one will notice; all of which will contribute to the sufficiency or insufficiency of the performance. Among these many things include costumes. Costumes are considered to be one of the most influential and important factors or aspects of the play itself. For example, the colors of the costume help to set the mode and theme of the play. If the play is considered to be a somber or tragic and sorrowful play, then the colors of the costume may be dark and morbid. The darkness of the costumes will add to the morbidness of the play. This is a considered to be a vital aspect by many to any play or performance. However, if a play is uplifting and happy and the costumes should also represent the same thing. They too should be uplifting and bright. Thus, the colors of the costumes should be bright and colorful. Therefore, a happy play representing colorful costumes on their actors is vital in the overall production of the play because it adds to the joyfulness and bright aura that is to be represented through the performance. Another important factor which importantly attributes to the success of a play is the sound or the music. Without the proper music, the play will not appropriately fit with the story-line as it should. For example, with a tragedy, such as Romeo and Juliet, much of the music is somber and sad. Without the emotion emanating from this music, the final influence of the production would not be the same as if the music were cheerful and happy throughout the entire play. Also, with a play that is cheerful and happy, the music must be cheerful and bright. Sound is vital in any performance and play. Without it, the play will be dull and unfitting with the plot of the story. The music adds to the emotion and the effect of the play. Next, the set itself is also extremely important in contributing to the overall success of the play or performance. It must be carefully detailed and match with the era or time that the play is supposed to be taken place in. For example, if you were having a play that was supposed to have taken place before electricity was invented and the set included objects such as light bulbs and television sets, this would conflict with the entire plot, because it would not make any sense. Thus, the set is extremely important. Another extremely and vitally important aspect that attributes to the success or failure of plays and productions are props. Props are anything from pots and pans to furniture and food. Whichever props are used in a play should be affiliated with the time period that the play was supposed to take place in, just as the set should be. Finally, our last and equally important attributing aspect for plays is lighting. Without the proper lighting a play can be a complete and utter failure. However, with the necessary lighting that is require to see each and every prop, background, and costume, the play should certainly be a success if all of the other aspects are followed through properly.

Gambling legalization Essay Gambling is the act of playing for stakes in the hope of winning (including the payment of a price for a chance to win a prize). (Oxford dictionary) Many have their own opinions about gambling and at this time gambling is not legally practiced here in The Bahamas. â€Å"Such a move would bring an end to an illicit industry that makes tens of millions of dollars a year and which employs hundreds; but which contributes little to the general good of the Bahamian people. † (The Bahama Journal 2008). There are many aspects of gambling that can indeed be looked upon positively. â€Å"Gambling comes in many forms, including betting in casinos, racetracks, sporting events, lotteries, bingo games and even virtual gambling on the Internet† (Oddo 2007) Gambling should indeed be legalized, because it will help our economy and society in many ways. If gambling is practiced it’ll give persons with idle time on their hands, something to do and it can also boost our tourism industry. The legalization of gambling here in The Bahamas will lead to an increase in the Bahamas’ Gross domestic Product (GDP), an increase in employment, and finally it can contribute to our entertainment industry. The legalization of gambling would be of grave benefit for our Government as it relates to the Gross Domestic Product In an article titled ‘Legalizing gambling in The Bahamas’ written by Craig Butler his argument for gambling was that the Prime Minister Rt. Honorable Hubert Ingraham should enforce gambling and put an independent company of auditors to oversee this new development. â€Å"If gambling is to be legalized then he must cause the infrastructure to be put in place that will avoid the inevitable attempts at tampering and manipulation by ingenious persons. † (Butler 2008). Once this takes place the Government will be able to implement a taxing system with our own internal revenue service (IRS) so that a certain percentage of the money i. e. twenty five percent will go to the Government in result more money would be spent on more capital goods, meaning more school’s will be built and more work infrastructure on our roads will be carried out. In America, Statistics show that approximately 92. 27 billion dollars comes from gambling on a yearly basis. If this same scenario would apply to us here in The Bahamas that will mean that gambling would be of benefit to our revenue and finance sector. Some believe that legalizing gambling would only allow the Government a free share of the money, and that share will only be spent on their own needs. They will use this money to purchase more cars for them to be chauffeured around in, to have more ‘business’ dinners for themselves, and to spend on five day trips all around the world and the economy won’t feel a dime of it. They are partially right because most people are used to politicians being voted in the House of Assembly and never coming around to visit their constituents, therefore they lack the trust in believing that the Government will deliver once they start to receive the percentage of winnings. However, they are misguided because the Government forecasts a certain percentage of money to go into capital goods every year during the budget and the normal percentage that is set aside for education and health care can rise and can be use more significantly. â€Å"But the legalization of this habit will not lead to an exponential rise in the number of gamblers. It will, however, allow government to fund programmes that can have a positive impact on our youth, such as community centres, sports and education facilities. † (Butler 2008) Mr. Butler makes it evidently clear in his analysis in the Bahama pundit that if the Government had the extra funds they would use it wisely. For example, there’s now a system set up by National Insurance for the unemployed. The unemployment benefit pays 100 dollars a week to those unemployed and if the Government receives more money this can to go up. Not only Bahamians will be getting taxed but foreigners as well. Therefore all of the foreigners that are here now using our casinos and going back with everything, would have to leave that twenty five percent tax fee for the government. Legalizing gambling would also lead to a decrease in the unemployment rate. In an article entitled ‘Gambling Entertainment’, it states that â€Å"The large percentage of employment provided by the Gambling industry, including the land based casinos as well as the Online casinos, puts gambling industry on the top of society chart straight away. † Having gambling legalized would automatically mean that employment will increase. At present Gambling is in the ‘underground economy’ mark when it comes to calculating the unemployment rate. Since it’s illegal workers are considered to be employed, however legally they’re counted as unemployed when it comes to the unemployment rate. In an article written by Olivia Saunders, Saunders illustrated the unemployment rate in a diagram that showed an unemployment rate of 7. 8 percent. Out of this 7. 8 percent count are the people that are already presently working for number houses, if we legalize gambling that rate would automatically decrease. Many are lead to believe that legalizing gambling won’t decrease the unemployment rate, because there are already a substantial amount of lottery houses opened already and there are still many unemployed, it’s impossible for this to help our unemployed, and even if it does, it won’t completely take care of the problem. They are partially right because legalizing gambling won’t lead to a complete decline in the unemployment rate, and it won’t be able to employ everyone without a job, however they are misguided because it will help tremendously. Legalizing gambling means that more lotto shops will be able to open, not only in Nassau but also on the family islands which will attract more tourists. Therefore they’ll need more staff, this will also lead to more casinos and more people will be hired in many different aspects. For example they’ll need cleaners, cashiers, coupe and hostesses. The real truth is there are many different aspects in our economy that contributes to the unemployment rate both increasing and decreasing and this rate can never be steady. However once gambling is legalized and there are more venues opened then it’s a necessity to hire people to work in them, and these people will then count towards the unemployment rate and it’ll then decrease. Finally the legalization of gambling can be used as a sport and a form of entertainment. The only form of gambling is not purchasing numbers from the lotto shops as some Bahamians are blindsided to believing, however it is also a sport. There was once a horse racing venue that was used as a sport over here in 1976 but had to leave because gambling wasn’t legal. Legalizing gambling would allow this form of entertainment to once again be practiced. In a journal named ‘Gambling The cost of our future,’ it indicates that ‘Those who participate in gambling activities do so voluntarily and, in return, receive intrinsic benefits from their consumption. Furthermore, if consumers are gambling for entertainment purposes, they are purchasing gambling just as they would purchase tickets for the cinema or a symphony. † (Basham, White). This statement raises a thoughtful argument because gambling is indeed a risk however this risk is on the same level of buying a cinema ticket and you’re not sure if the movie will play or a symphony and you’re not sure if you’ll enjoy it. Opponents believe that having gambling as sports can only lead to more financial problems for an unstable financial home. They may argue that gambling is an addictive game and some families aren’t ready for the strain that this addiction entails, and some people may be willing to do anything to satisfy this addiction like commit robbery. Gambling addiction is also referred to as compulsive gambling or pathological gambling. Medical Author Roxanne Dryden-Edwards raise a valuable point in her article ‘Gambling Addiction’ stating that â€Å"The number of people who gamble socially qualify for being diagnosed with a gambling addiction range from 2%-5%, thereby affecting millions of people in the United States alone. † (Dryden- Edwards) Some may debate that If The Bahamas population is only 316,000 compared to the United States, then our percentage will be more harmful if gambling is practice. But they are misguided because this entertainment and sport may not be addictive but relatively fun and exciting and a good family event for most, even though there may be some bad apples the pros may outweigh the cons. The real truth is that almost everything we do as a form of gaming exercise is pleasurable and having more opportunities will make gambling more enjoyable. The Government can also implement a system so that gamblers that develop the addiction can be fully taken care of and receive psychiatric help called Gamblers Anonymous’ (GA). According to the the 12 step recovery program statistics â€Å"Of those in their fourth month of AA meeting attendance (i. e. have stayed beyond 90-days) 56% will still be attending AA at the end of that year. † (Holding all others constant if this system is practiced here with addicts treatment will be beneficial. In conclusion, gambling can contribute to our economy significantly. Many feel as though gambling will cause more harm than good, however if it’s practiced correctly and everyone abide to the laws that would be put in place, gambling will be more than just an easy way to win a substantial amount of money it’ll be a form of entertainment for many, it’ll be a sport that can be family orientated and finally it can be a way for our economy to jump back into the expansionary boom period and no longer claim that we are in a recession.

Calculations Without Brake Booster Engineering Essay

Calculations Without Brake Booster Engineering Essay The purpose of this written assessment is to show that we understand how the braking system works in an automotive vehicle. We should be able to show a range of specialized technical skills which involve a wide choice of standard and non standard procedures. I will also show you a broad knowledge base with substantial depth in some areas of the braking system. Here in this assignment I will also cover the determination of appropriate methods and procedures in response to a range of concrete problems with some theoretical elements and apply it in self directed and sometimes directive activity, within broad general guidelines. By the end of this assessment I will have a wide understanding of how the braking design and braking system work within the automotive vehicle. A brake is a device for slowing or stopping the motion of a vehicle or a machine, and to make sure that it stops moving. The kinetic energy lost by the moving part is usually translated to heat by friction. Alternatively, in regenerative braking, the energy is recovered and stored in a flywheel, capacitor or other device for later use. Brakes of some description are fitted to most wheeled vehicles, including automotive vehicles of all kinds, trains, motor bikes, and normal pedal bikes. The kinetic possessed by a vehicle at any one time into heat energy are by means of friction. The equations for kinetic energy, that is the energy of motion may be given by: The disc brake is a device for slowing or stopping the rotation of a wheel on a vehicle. A braking disc or commonly known as a rotor, is usually made up of steel and other metallic compounds, is connected to the wheel or the axle. To stop the wheel, the braking pads which are normally mounted in a device called a brake caliper, which is then squeezed mechanically or hydraulically against the disc on both sides. Friction causes the disc and attached wheel to slow down and stop according to the driver. A drum brake is a brake in which the friction is caused by a set of shoes or pads that press against the inner surface of a rotating drum. The drum is connected to a rotating wheel. The modern automotive vehicle drum brake was invented in 1902 by Louis Renault. In the first drum brakes, the shoes were mechanically operated with levers and rods or cables. From the mid 1930s the shoes were operated with oil pressure in a small wheel cylinder and pistons, though some vehicles continued with purely-mechanical systems for decades. Some designs have two wheel cylinders. Experiments with disc-style brakes began in England in the 1980s the first ever automobile disc brakes were patented by Frederick William Lanchester in his factory in 1902, though it took another half century for his innovation to be widely adopted. The first designs resembling modern disc brakes began to appear in Britain in the late 1940s and early 1950s. They offered much greater stopping performance than comparable drum brakes, including much greater resistance to brake fade this is caused by the overheating of brake components, and were unaffected by immersion which is drum brakes were ineffective for some time after a water crossing, an important factor in off-road vehicles. Disc brakes are also more reliable than drum brakes due to the simplicity of their mechanics, the low number of parts compared to the drum brake, and ease of adjustment. Disc brakes were most popular on sports car when they were first introduced, since these vehicles are more demanding about brake performance. Many early implementations located the brake disc inboard, near the differential, but most discs today are located inside the wheels. An inboard location reduces the un-sprung weight and eliminates a source of heat transfer to the tires, important in formula one racing. Discs have now become standard in most passenger vehicles, though some retain the use of drum brakes on the rear wheels to keep costs and weight down as well as to simplify the provisions for a parking brake or emergency brake. As the front brakes perform most of the braking effort, this can be a reasonable compromise. Mechanism A single piston, floating caliper system. Pressurized brake fluid travels along the brake line to the caliper. The pressurized fluid pushes the piston (green) and inner brake pad against the disc which is normally blue. Pressure against the disc pushes the caliper away from the piston, pulling the outer brake pad against the disc. As the brake pads clamp together, friction slows the rotation of the disc and wheel. Brake Pads The world of Automotive Brakes can be quite overwhelming. The first task in choosing Automobile Brakes is making sure that you have the Automotive Brakes and parts that are application specific to your vehicle whether it be a car, truck, van or whether the Automotive Brakes are to be installed on a two year old sedan or a rare classic. There is more to Automotive Brakes than parts that fit. Automotive Brakes also have to be right for the vehicles actual use. For example, Automotive Brakes required for off road or stop and go city delivery driving can be quite different than Automotive Brakes that are suited for ordinary family driving, even though all these brakes fit the job. Its a matter of finding the right Automotive Brakes for your application. Brake Pads Brake Booster Unless youre a professional athlete with tree trunks for legs, be grateful that your car has a brake booster nestled between the brake master cylinder and firewall on your car. Your brake booster doesnt make any noise, and it doesnt use any electricity or gasoline, but it ensures that you can stop your car with only a light touch of the brake pedal. Things werent always like that, Before the invention of the vacuum brake booster, cars still stopped. Its just that you had to really stomp on the brake pedal. The modern brake booster is an good device that operates using something that your engine generates whenever its running, Vacuum. The brake booster takes engine vacuum via a rubber hose that runs from the intake manifold, and the brake booster uses that vacuum to amplify the pressure you put on the pedal. A light application of the brakes is translated by the brake booster into significantly more pressure on the brake master cylinder, ensuring that your car stops quickly. So what happens to the brake booster if your car stalls, resulting in a loss of engine vacuum? Early designers realized that gas engines were hardly foolproof, so they designed a little check valve into the brake booster circuit. The brake booster stores enough vacuum to provide full boost for two or three pedal applications even after the engine dies. The check valve on the brake booster is what keeps that vacuum from leaking out. And speaking of leaks, thats the reason most brake booster units have to be replaced. As your brake booster ages, the rubber seals and diaphragms that hold the vacuum tend to wear out and crack.

If youve ever seen or worked on a brake caliper, you know what were talking about. The brake caliper is a U-shaped device with a piston or pistons on one or both sides of the U. The brake pads ride on top of the brake caliper pistons, and the rotor spins in the channel of the U. When you hit the brakes, high-pressure fluid is channeled from the master cylinder down to the brake caliper where it pushes the piston or pistons inward. That brake caliper action moves the pads against the spinning brake rotor, and the friction stops your vehicle. Since the brake caliper is affixed to your vehicle frame and the rotor is spinning and hundreds of RPM, its easy to imagine the massive forces that the brake caliper has to absorb. Much of the heat energy is dissipated by the rotor and pads which is why theyre replaced the most, but the pulling and twisting forces the brake caliper has to endure require that it be extremely strong. More than anything else, though, its the hydraulic brake fluid that leads to the demise of a brake caliper. If its not changed often enough, moisture in the fluid will begin to rust out the inside of your brake caliper, resulting in leaks and sticking pistons. Eventually the brake caliper will cease to function altogether, it will effect your cars stopping ability. Calipers The brake caliper is the assembly which houses the brake pads and pistons. The pistons are usually made of aluminum or chrome plated iron There are two types of calipers: floating or fixed. A fixed caliper does not move relative to the disc. It uses one or more pairs of pistons to clamp from each side of the disc, and is more complex and expensive than a floating caliper. A floating caliper (also called a sliding caliper) moves with respect to the disc; a piston on one side of the disc pushes the inner brake pad till it makes contact with the braking surface, then pulls the caliper body with the outer brake pad so pressure is applied to both sides of the disc. Floating caliper (single piston) designs are subject to failure due to sticking. This can occur due to dirt or corrosion if the vehicle is not operated. This can cause the pad attached to the caliper to rub on the disk when the brake is released. This can reduce fuel mileage and cause excessive wear on the effected pad. Brake caliper In a vehicle the brake pedal in 360mm and the booster is connected 50mm from the pivot. The booster diaphragm is 220mm with the valve body of 52mm diameter the diaphragm return spring has a pretension force of 80N and rate of 12N/mm.

Some are simply solid steel and some are made up of carbon fibers, but others are hollowed out with fins joining together the discs two contact surfaces usually included as part of a casting process. This ventilated disc design helps to dissipate the generated heat. Many motor bikes and sport car brakes instead have many small holes drilled through them for the same purpose. Additionally, the holes aid the pads in wiping water from the braking surface. Other designs include slots shallow channels machined into the disc to aid in removing used brake material from the brake pads. Slotted discs are generally not used on road cars because they quickly wear down brake pads. However this removal of material is beneficial to race cars since it keeps the pads soft and avoids verification of their surfaces. Some discs are both drilled and slotted. Pistons cylinders The most common caliper design uses a single hydraulically actuated piston within a cylinder, although high performance brakes use as many as 8. Modern cars use different hydraulic circuits to actuate the brakes on each set of wheels as a safety measure. The hydraulic design also helps multiply braking force. Failure can occur due to failure of the piston to retract this is usually a consequence of not operating the vehicle during a time that it is stored outdoors in adverse conditions. For high mileage vehicles the piston seals may leak, which must be promptly corrected. Parking brakes Most vehicles include a mechanical parking brake system also called an emergency brake which operates on the rear wheels. These systems are very effective with drum brakes, since these tend to lock. The adoption of rear-wheel disc brakes caused concern that a disc-based parking brake would not effectively hold a vehicle on an incline. Today, most cars use the disc for parking, though some still rely on separate drums. An emergency brake is a braking system that is generally only to be used in emergency situations to slow or stop a machine. The most well known emergency brakes are those in trains and automotive vehicles. Many people shorten emergency and call the devices e-brakes. Additionally, in the automotive side, they are also known as parking brakes and hand brakes. In cars, the emergency brake is a supplementary system that can be used if the vehicles primary brake system has a failure. Automobile e-brakes usually consist of a cable directly connected to the brake mechanism on one end and to some type of lever that can be actuated by the driver on the other end.

It is essential that we know how the brakes work, and it is important to use the right type of brake pads for each different driving application. Some brakes work well once they are heated up and some work well in the colder conditions. So when we go get our brake pads changed its up to the mechanic to make that call to see what pads should be used for the correct braking situation. This will save damage to the brake disc and stop it from causing further damage to anything else. My concept is to some how get a recording device or some type of sensor that has a memory in which it recalls everything that you have done in regards to the braking system and the brake pads. This will keep a record of your amount of braking you have done and also what type of conditions you have been driving in. So this could tell you that you have been driving in a cold area but doing lots of braking , so when it come to changing these pads you could just unplug the sensor and check and make your own decision upon the type of pads that will suit to your braking application. Advantages of this concept are: The temperature will always be monitored You know exactly when you need to change you brake pads You know how much you are actually using the braking system You know exactly which brake pad is suited for the application No problems of over heating You know if there are any problems in regards to damage of brakes or discs

The Values, Ideals, and Actions of Fanny Fern Essay -- Fanny Fern

The Values, Ideals, and Actions of Fanny Fern   Ã‚  Ã‚   Literature from the 1820à ¢s to the 1860à ¢s brought attention to the expanse of the American experience and gave rise to many unique voices. Some of the best writers of this era challenged their fellow citizens to live up to the ideals that the founding fathers had written into America's sacred documents. The voices that cast these challenges are as varied and wide spread in their approach as this nation's natural boundaries are diverse. Fanny Fern (1811-1872), was one of the writers who made a big splash with her fearless unconventionality during this literary renaissance. Her masterful use of satire and her belief that the ideal of individualism should include women, gained her enormous popularity and doomed her chances of being included in the American literary canon for over a century.    Fanny Fernà ¢s real name was Sarah Payson Willis Parton, but she used the pseudonym in all her legal affairs and with members of her family. Similar to Mark Twain in the sense that the pen names became more closely associated with the writers than their real names, Fern, like Twain, wrote satirical essays, sketches, and novels about the shortcomings of American society. For twenty-one years Fern reminded people that America needed to work on it problems with literature, education, prisons, prostitution, venereal disease, family planning, divorce, education, child rearing, and rights for women. Her unflinching, yet female perspective gained her enormous popularity. Although Fern did not completely abandon traditional womenà ¢s topics like love, marriage, and children, the most far-reaching issues that she addressed were economic independence for women and the need for improvements in dome... ...cked to comprehend and remember the attack, and to see a direction they may take for correction (Harris 15)." Fern gave us the ironic contrast between American citizensà ¢ values, ideals and actions.       Works Cited Emerson, Ralph Waldo. "Self Reliance." The Heath Anthology of American Literature. Ed.

Methods to Increase Learning and Success Among Students

The government is now looking into ways of increasing the learning experience of students they could use in the competetive reality of life. The C. S. Mott Foundation suggests that â€Å"the time is ripe to shatter the ‘chalk and talk', 8 a.m. to 3 p.m., September to June concept of school, and stretch and reshape learning time in order to improve student achievement† (Stedron 2007).In his article, â€Å"A new day for learning: its time to look at changing the length and scope of the school day to help kids succeed† Jennifer Stedron enumerated some ways to increase students' learning and explains the advantages of each. Three options were offered: to incorporate summer learning, out-of-school learning or increasing the length of time for a school day or school year.The advantage of including summer learning programs lies with the additional learning experience for students that can prepare them for the next stage of learning.Stedron (2007) held that â€Å"disadva ntaged students tend to fall behind during the summer because of a lack of learning opportunities in the home and community. By fifth grade, this summer slippage accounts for approximately two full years' deficit in reading comprehension levels.†The executive director of Johns Hopkins University Center for Summer Learning held that the differences in summer learning â€Å"account in part for later educational outcomes† (Stedron 2007).New Mexico's Plus Pilot Project, which provides an optional program of at least 40 additional days of school during the summers before and after kindergarten, has resulted with students gaining early literacy skill and social maturity which can considerably prepare them better for the first grade.Out-of-school activities can also increase students learning experience. â€Å"Before- and afterschool programs reinforce the school curriculum and broaden student skills through enrichment activities that might be absent from 8 a.m. to 3 p.m.â₠¬  according to Stedron (2007).She held that â€Å"extra† subjects such as art and music, which have been cut but many schools in favor of the more practical subjects, are â€Å"often what keep some children engaged in and attending school† (Stedron 2007).California Senator Tom Torlakson said that kids get excited about learning and their attachment to school increases since they have to attend school to attend these out-of-school programs.Aside from getting better results from students, investing on these programs will also generate budget savings for the government. Stedron (2007) used the California After School Education and Safety Initiative program as an example of the advantages of out-of-school programs: â€Å"evaluations show increase in student attendance, achievement and good behavior from kids in the programs.And a 50 percent decrease in students who must repeat grades is saving the state the massive expense of an extra year of education for many students .†Nothing can increase learning experience better than extending instructional time, which may be through, but not limited to, summer learning or after-school programs.Stedron, however, stresses that it is not just more school time that the students need. â€Å"They need to opportunities to develop creativity and be leaders† (Stedron 2007). For older students, this may include internship programs which give the students time to learn in the real world.Milt Godlberg, a member of the national Time, Learning, and Afterschool Task Force, believes that â€Å"young people are more engaged in learning and are more motivated when activities are not restricted by the traditional classroom structure† (Stedron 2007). Education should, after all, not be confined within the four corners of the classroom, but must also incorporate the realities of life.Stedron has given profound insights about the topic. Although the claims are not supported by statistical evidences, she has p rovided a convincing argument by providing student reactions and comparisons with the traditional way of learning.Increasing learning experience, not just academically but socially, will benefit the students by also increasing their knowledge, skill, and competetiveness, all of which will consequentially increase their chances of achievement and success.ReferencesStedron, J. (2007). A new day for learning: Its time to look at changing the length and scope of the school day to help kids succeed.

International Communication Focusing on Fifa 2014

Vuvuzelas sound and it fills the stadiums with a noise that is still heard ringing in the ears of millions days later, even months after it has ended. The overwhelming feeling of excitement spreads through the veins of everyone watching and those on the edge of their seats just waiting for the next goal to be scored, determining who wins the world cup and takes home the famous gold â€Å"FIFA World Cup Trophy. † The World Cup is a tournament that comes every four years and lasts a month long with tournaments every day from June 13th- July 13th The World Cup brings in a whirlwind of excitement and emotions. This victorious event will be held in Brazil in the year of 2014 but before June 13th hits, there is a massive amount of planning to be done. With all the preparations leading up to the World Cup we will capture the trials and tribulations through the eyes of four locals in Rio de Janeiro. First, we will film one year before hand and capture everyday life without the World Cup. We will take a look at how Brazilians live their lives on a day to day basis without the chaos and media attention of the event. We will do this by following four individuals, interviewing them about how they feel about the World Cup and how it is affecting their daily routine. Our second round of filming will place our crews with the same four peole on the day of the first game in Rio de Janeiro. The World Cup takes the world by storm every four years. While in America, soccer has just recently gained a large following, it has been a way of life for generations in many countries throughout the world. We can identify with this phenomenon somewhat if we relate it to the impact of the Olympics when they were held in Atlanta, Georgia in 1996. An event of this scale becomes all-consuming and places the city and country under a worldwide microscope. The World Cup produces a whirlwind of excitement with years of preparation that costs and generates millions of dollars. Many sports in America have a strong following and fan-base, but nothing can truly be compared to that of soccer overseas. Countries such as Mexico, Spain and Brazil look at soccer, its players, and the games, as a way of life. Brazil especially has been known for its talented and renowned soccer (â€Å"futebol†) team throughout the years and they have won five World Cups. From the outside looking in, Brazil has been known as one of the powerhouses, if not the powerhouse of soccer worldwide. The fact that FIFA and all of the other governing and deciding bodies have chosen to place the World Cup 2014 in Brazil generates further excitement, but also places this country under close watch from viewers worldwide. As we saw with the World Cup 2010 in South Africa, a country can be drastically altered and affected by such a large-scale event. We want to create this documentary to shed light on the impacts, trials and jubilation of such an incredible event. While many see the benefits of hosting such an event, there are plenty of drawbacks as well. We want to create an in-depth look of this phenomenon, the World Cup, and show also how it affects the country that is producing the event. So much goes on behind the scenes and many lives are impacted, whether negatively or positively. By following four real people with everyday jobs and average, normal lives, we hope to inform the public of the on-goings of the preparation for the World Cup, as well as how individual lives are impacted. We want to follow four people; a ticket scalper, police officer, a fan and a street vendor. Through this we hope to achieve a more personal view of such an immensely grand event. We want to inform the public of the preparations involved in the World Cup as well as the madness that ensues once it all begins. We will chronicle this massive worldwide soccer tournament through the eyes of normal everyday Rio de Janeiro citizens in the attempt to show a real-life perspective of a fantastical and media-centric event. While there are documentaries aplenty, ours is unique in that it shows the impact on a country and its citizens, something many viewers of the World Cup never consider. By creating a personal and impactful narrative that comments on economic repercussions, nationalism and pride, we hope to appeal to viewers who want to see a cultural view of soccer that has never before been created. Nicknamed â€Å"Cidade Maravilhosa† — Portuguese for â€Å"marvelous city† — Rio de Janeiro conjures many images including Ipanema Beach and the famous Cristo Redentor statue atop Corcovado Mountain. But in 2014, one of the most important global sporting events, the World Cup, will arrive in Brazil where soccer — or futebol as they know it — is the lifeblood of the culture. After FIFA announced Brazil as the hosts of the 2014 World Cup on October 30, 2007, a different set of images would materialize for the population of Rio de Janeiro. Once upon a time it was the site of the final match of the 19 50 World Cup in Maracana Stadium. Uruguay came from behind to beat its host 2-1, even though Brazil was heavily favored after eliminating previous opponents Spain and Sweden. Since then, Rio de Janeiro has been home to some of Brazil’s most popular soccer clubs: Botafogo, Fluminense, Vasco da Gama and Flamengo. With a past and present such as this, tensions and expectations will undoubtedly be high, especially where soccer is so inter-meshed with their culture. Choosing to film in Rio de Janeiro will capture much of this drama associated with the World Cup as we follow our four subjects: the police officer, the fan, the street vendor and the ticket scalper. In general, we want to keep the area surrounding Maracana Stadium as our locus of interest, but this isn’t necessarily realistic. The subjects have dynamic lives each and every day, especially as the World Cup draws closer, so it may be difficult to remain under the shadow of the venue. As each subject travels through different areas of the city, the camera crews will have to make critical judgment calls about when to uncap the lens. Our film crews can expect to capture the best footage in some of Rio de Janeiro’s most exciting sites. The city is known for its soccer, tourism, night life and beaches, but we will want to focus on the North Zone. It contains several neighborhoods and important tourist attractions, including our primary filming location, Maracana Stadium, which is located in the Tijuca neighborhood. It is home to many of the middle class residents and also the lower class favelas, which are crime-ridden neighborhoods filled with poorly built shanties. Our police officer will certainly be answering calls from this poor section of Rio de Janeiro where our ticket scalper is a resident. Our street vendor and soccer fan will also be residents of the Rio North Zone. It is there in the North Zone that we will want to follow each of our characters into their homes. Once inside their homes, our camera crews can film the effects of the World Cup on the Brazilian household unit. We will discover just how the home family life is transformed both demographically and psycho-graphically. Questions can be answered such as: a) Has new disposable income, as provided by the World Cup’s economic opportunities, increased the family’s standard of living? b) Has Brazilian pride in its national sport entered the home life? c) Has the importance of home security changed due to the hysteria associated with the World Cup? Once these questions are answered, a more complete view of the character is revealed and analyzed by the audience. Another set of important sites will be public centers for transportation. The primary modes of transportation are by municipal train and bus lines since driving by car is very difficult. Due to a great deal of highway congestion, cars often move at a snail-like pace. Important themes will manifest themselves as we travel to and from each location. These places, which are usually replete with a colorful culture, will be amplified in the presence of the World Cup. The documentary will actively connect the dots between Brazil’s national pride and their national sport at these various locations. The Maracana Stadium will be the most important site. There we will capture each of our characters’ paths intersecting outside and inside the venue. The fan will obviously be destined for the stadium itself; the street vendor will set up shop as close to the stadium as possible so as to snag the most consumers as possible; and the policeman will have critical interactions with the ticket scalper, who will be acting against the law. Many memorable characters exist in a documentary just like any other genre of film. The goal is to capture reality but there is no need to move away from the act of story telling. The idea behind the characters of our documentary is that they are all connected through each other by the duties they perform throughout the documentary.. Our first character to appear is the police officer. Juan Sminho is 38 and works for the Rio de Janeiro tourist police. He performs regular policing in the streets of Rio by assisting tourists and pointing them in the proper direction to where they are headed. Juan also performs similar duties to what the united states police force does but he is not as involved with crime as our police forces are. He lives on the north side in a two bedroom apartment with his wife and brother. He does not come from a wealthy family but did inherit some from his parents when they were murdered 10 years ago in a robbing which pushed him to become part of the Brazil police force to keep things like that from happening to other families. He will show the audience what it is like in everyday life as a tourist officer, then there will be a dramatic change of pace a year later on the chaotic streets of Rio where his duties are truly put to the test with all the tourist in town for the World Cup games. Juan’s duties will be to perform crowd control, assist tourists and seek out ticket scalpers; this is a highly illegal offense in Brazil. Most everyone has seen a ticket scalper before, but if not, they are the ones that stand on the corners of concert/sport venues and sell those last minute tickets needed for the fans. Ticket scalping is very illegal in Brazil and punishable by jail time, but that does not stop our scalper from risking it all for some extra cash. We will follow Gustavo Silva, a thirty-four year old Rio native who has never left the North region. He works as a ticket scalper primarily, but during the slow months tries to make ends meet by helping out at his parents' modest fruit stand in the outskirts of Rio. The popularity of soccer as a sport, particularly in Brazil, directly effects his livelihood and well-being. Seeing Gustavo in his element both before and during the World Cup will create a dynamic story for the viewers. Viewers will identify with Gustavo's endearing and persuasive personality because of his hard-working attitude. Ticket scalping just became illegal in Brazil, which is obviously a threat for Gustavo. The documentary will show the discrepancies in this law as it is not seriously enforced until the World Cup in 2014. The effects of this on Gustavo will prove to be detrimental. With money being tight and having to find work wherever possible, some residents of Rio do not have a choice. Our team has high hopes for our scalper that he will sell a ticket to our next character, the fan. What is a team without its fans; similar to a sandwich without bread. A sandwich does not exist without bread much like a team would be nowhere without fans. Soccer fans have been seen taking their â€Å"fandom† to the extreme, but the more extreme it is, the more the team feels honored and welcome. Brazil soccer fans are famous throughout the world for their enthusiasm and carnival atmosphere at the World Cup. Many soccer managers will often claim that soccer fans can act as an extra man or the infamous â€Å"12th Man† and this is certainly the case when Brazil plays in front of over 100,000 soccer fans at the famous Maracana Stadium. The fans are not always as supportive though, in fact, they can be rather harsh. This was shown when the team came home after the 2006 world cup without a win, according to Kevin McNally of E-zine Articles. We hope to capture all this excitement while following around our dedicated fan, if Brazil loses then it is possible that our film gets even more interesting with the outrage that the country will have on them. Choosing a fan for our documentary was tough but we have found one who truly shows the spirit needed to connect with our audience. Paulo Cardoso is originally from Rio and lived there until he was 18. Once old enough, he moved to the United States to attend college but soon wanted to return to his home country after graduating. Paulo is a business major but is currently working at his parents coffee shop as a manager to help them out. He is 28 and has been an avid futebol fan since he was born, according to him. Every four years he gathers around the big screens in Rio to watch Brazil triumph, or try to, over their competitors. He will take us through the festivals in Rio including â€Å"Fan Fest Rio 2014. † His grandfather attended the World Cup in 1950 when it was last held in Brazil followed by the World Cup in 1978 held in Argentina and this time Paulo’s father went alongside. Paulo has been saving as much money as he can to be able to hold the tickets that so many others strive to have. He does not plan on buying a ticket before the games due to hopefully cheaper prices on game day. He will be a huge help on guiding us around Rio due to our unfamiliarity to the city. Paulo brings to the documentary the familiar language of English but with the Brazilian traditions that we could all stand to learn from. He as well as many other fans will interact with many people but as always, he will buy some form of merchandise from a street vendor before the game. This will allow for our fan and street vendor to interact with one another. There will be a numerous amount of street vendors trying to sell anything they have that represents the world renowned Brazil â€Å"Futebol† Team. Our film crews will follow around one vendor who sets up shop close to the stadium in hopes of catching the most business. Gearing up for the World Cup takes a lot of preparation, which is why it is imperative that we catch her one year before hand before she starts ordering merchandise and preparing for the mass amounts of fans to flood the city of Rio. Claudia Trigoso, 26, lives in the favelas in the North Zone of Rio de Janeiro. Under normal circumstances Claudia deals with irregular employment due to his low socioeconomic standing, but the arrival of the World Cup will give her the opportunity to transform her situation. She has applied to Eurosport catalog to sell some of their merchandise near Maracana stadium. Soon, with the proper licenses, she will be cleared by Rio’s municipal administrators to set up in this area. Claudia hopes she can make enough profit to start a business of her own after the World Cup and its excitement wane. With this in mind, she might someday have the opportunity to move out of the North Zone favelas into a safer, more affluent neighborhood where she hopes to start a family of her own. In addition to highlighting the changes from life before the World Cup to life uring the tournament from the perspective of our four main characters, our camera crew will venture out into the streets and local pubs. Our crew will conduct first-hand interviews with everyday citizens to get a better grasp on the impact of the World Cup on the people of Rio. The filming crew will ask the public questions pertaining to how the World Cup has economically impacted their businesses, their transportation around the city, and whether or not they will be watching or attending the World Cup. There are many components that go into making a documentary outside of the characters, locations and themes. While the overarching themes will make a large impact on our viewers, the intricate details disbursed throughout the film will contribute drastically to the overall feel of the documentary. Throughout the documentary our characters and locations will be introduced using typewriter text as it is typed across a blank screen. The segments will not necessarily be rigidly formatted but the characters will be introduced as they fall into place in the documentary. Aside from the interviews included in our film it will primarily remain in the observational category of documentary film making. By taking a third-party neutral approach to the film the audience will get a realistic and personal view into the lives of the residents of Rio. Our documentary will target a large demographic due to the emotional and sports aspects as well as the excitement generated from the FIFA World Cup overall. We hope to target ages eighteen to fifty by placing this sixty minute documentary on a major network such as ABC. We initially contemplated airing the documentary on ESPN because of its sports focus, but eventually agreed that ABC would be the best choice. Not only is it a well-respected major network, but our aim is to capture the World Cup viewers for our documentary. By airing Joga Bonito on the network that is already broadcasting all of the World Cup games, we will grab the attention of the avid soccer fans who will hopefully already be watching ABC (the World Cup games will be used as somewhat of a lead-in for our documentary). In order to generate even more viewers, we will air advertisements throughout the month of the World Cup tournament to create buzz and excitement. Throughout this month, the public will have plenty of time to hear and read about our documentary. The documentary â€Å"Joga Bonito† will air as a prime-time special a few days before the World Cup finals. The title of our documentary, Joga Bonito, is meant to evoke the spirit and essence of soccer and of Brazil. This term is Portuguese for â€Å"The Beautiful Game† which is commonly used to describe Association football, also known as futebol or soccer. When soccer was originally created and rules were formally established, it was referred to as â€Å"The Simplest Game†. This eventually evolved into The Beautiful Game, or Joga Bonito, when a famous Brazilian player named Pele named his biography The Beautiful Game. Because this term is now widely used when referring to the sport of soccer, and because of its roots and foundations in the country of Brazil, we saw Joga Bonito as a fitting title for our documentary. Joga Bonito will, as previously stated, offer to its viewers a discourse of national identity and the impact of the World Cup on the citizens of Brazil within the context of an emotional adventure through the streets of Rio. The juxtaposition of a personal look at the four characters and the mainstream international media event known as the World Cup will create a unique and powerful documentary. This concept appeals to the masses because it addresses a worldwide event. Within this discourse, however, we visit the personal implications of such an event and the role of nationalism and pride within an international context. By contrasting life before the World Cup with life during one of the first games, the drastic cultural and societal changes that occur in preparation of such an event will be highlighted. The emotional appeal of this documentary will intrigue viewers while informing them of international life and the results of an event that thrusts a nation into the international spotlight.

James Cameron’s Science Fiction film “Terminator II” Essay

James Cameron’s Science Fiction film â€Å"Terminator II† uses various conventions of Sci-Fi to not only engage viewers, but entertainment them. Science fiction uses various futuristic elements to convey powerful comments about society. This is most effectively done through his powerful and relatable social comments. His central social comments force audiences to question their own world and like all Sci-Fi texts explore how possible this actually is. The dominant social comment explored by James Cameron is that Technology will be our downfall. Other social comments that are also relevant are that humans have an intrinsic need to adhere towards morals and ethics that can’t be taught and that it is in the human race’s nature to destroy themselves. James Cameron clearly explains the social comments through various film techniques. Similarly, Henry Slesar’s short story ‘Examination Day’ relies heavily on its powerful social comment to effe ctively engage readers. While both texts make significant social comments, various other sci-fi conventions are also used to keep responders entertained. The dominant social comment that entertains the audience in an effective way explored by James Cameron is that technology will ironically be our demise. Cameron cleverly juxtaposes the opening scene of the hustle and bustle of lively Los Angeles to the close up traffic in 2029. However, in this shot the cars are destroyed and an empty playground further indicates the dystopian world of our society. The diegetic laughter of the girl on the swing and the non-diegetic music in the background creates suspense. The extreme white fade out to a dramatic close up of the empty swing swinging back and forth which then brings us to the close up camera shot of a human skull being crushed by the terminator clearly reveals that technology will lead to our demise. With the war of the robots being shown in the opening scene, audiences can immediately conclude that the genre of thriller is brought to the film as suspense is immediately introduced in the opening scene. This war indicates from the outset that technology will be our demise. While the irony of machines destroying humanity is immediately established as a significant social comment in this sci-fi text, Cameron begins to explore the characteristics of humanity in his second social comment. Throughout the film, Cameron relies on the humorous juxtaposition between the T100 and John Connor to highlight the emotional and idiocentric characteristic that are inherently human. It is through this and several other film techniques that Cameron’s second social comment is explored; that being human, is not something that can be taught. The moral and ethical justifications that are intrinsic to being human is clearly explored in the scene where John attempts to explain why, â€Å"You can’t just go around killing people†. John’s dialogue is contrasted with the T100’s question; â€Å"why not?† close up camera shots of their contrasting facial expressions highl ights this significant idea, that despite our natural inclination â€Å"destroy ourselves†, reason and morality is only inherent to us Johns invalid explanation, â€Å"because you just can’t †¦ this stuff is important†, highlights the barrier between machine and human. Through this social comment audiences can easily link the text to the science fictional genre. This barrier is further explored when John humorously attempts to ‘humanise’ the Terminator. Through various satirical scenes Cameron reveals humanity’s saving grace is intact their emotions which are ironically aligned to weakness. When the T100 asks, â€Å"why do you cry?† The T100’s crying motif mixed with several film techniques symbolises the disparity between machines and humanity. In an age where technology is seen to advance the human mind, the T100’s inability to understand why people cry highlights the superiority of humans, â€Å"we just cry.† Again further explaining the social comment we can still relate the film to the sci-fi genre. The third idea explored by Cameron is the ironic self- destructive behaviour of humanity. Using real life examples Cameron attempts to create a logical link between the creation of the destructive, ab ominable Terminators and the weapons that are already leading us into destruction â€Å"it is in your nature to destroy yourselves†. While the terminator metaphorically highlights the paradox of our constant creation of destruction, it is the female protagonist Sarah Connor, who provides a fresh face and new insight into sci-fi revealing the contrast between the destructive creation of men and the beautiful, creation that only women are privileged to endure, â€Å"Fucking men like you built the hydrogen bomb. Men like you thought it up†¦ You don’t know what it’s like to†¦ create a life†¦ All you know how to create is death†¦ † . Her use of repetition and expletives highlights Cameron’s feministic approach to this social comment, symbolising men’s obsession with creating destruction. This not only makes this sci-fi film unique and original in its exploration of this common theme, it also allows audiences to question why humans are so obsessed with playing â€Å"God†. Similarly to ‘Terminator II’ the short story ‘Examination Day’ also explores Sci-fi convections in similar ways. Like ‘Terminator II’, ‘Examination Day’ is driven by its powerful and dramatic social comment. While subtly revealed to be set in the future, unlike ‘Terminator II’ this is not the dominant focus in the text. While the commentary is different to that of ‘Terminator II’, both texts entertain audiences primarily by focusing them to question their own lives like all sci-fi text, thus posing the ‘what if’ question. The short story ‘Examination Day’ hyperbolically explores a world where governments obtain ultimate control. This is brought to the readers in the opening paragraphs when Dickies parents are discussing a â€Å"Government intelligence test they give children at the age of twelve†. It is â€Å"the moisture in his mother’s eyes† when readers are aware that the story they have been told has contrasted what really is happening. Even though the links to sci-fi aren’t as clear as the ones in ‘Terminator II’ we still see the connection through the thriller genre. As both Mr and Mrs Jordan try to avoid the conversation about the test suspense begins to develop as we understand that the test will possibly resemble a big part in the Jordan family’s life. As Mr Jordan explains the details of the test further we learn that the government will provide Dickie with truth serum. In this event readers are immediately informed that the government play a big role in everything which is making civilization less utopian and more dystopian. Is through little key things during the story we can see a resemblance to a futuristic world such as ‘Terminator II’, â€Å"Your classification number is 600-115†. Unlike ‘Terminator II’ this short story utilises various literary techniques to explore this powerful social comment, relying on descriptive language and body gestures to capture the mystery and anxiety relating to this exam. Furthermore the repetitive image of the â€Å"moistness of his mother’s eyes† heightens suspense, hinting towards the significance of this â€Å"Government intelligence test†. Like ‘Terminator II’ this text uses various sci-fi conventions such as the embedded t hriller genre to effectively engaging audiences, keeping them entertained. As the denouement reveals the unpredictable twist, â€Å"we regret to inform you†¦ his intelligence quotient is above government regulation†, the disturbing social comment become clearer â€Å"†¦whether you wish his body interred by the government, or would you prefer a private burial place?† Slesar’s clever use of inversion as Dickie fails the intelligence test because he is too smart, seems to be warning readers about the dangers of power and control, and the need for people to be more engaged and aware of governments and other organisations that may abuse their power. Like most sci-fi texts, ‘Examination Day’ challenges our own world, and contemplates what may happen if we do not take more responsibility and interest in the powerful bodies that govern the people. Again, it is this dramatic yet relatable social comment that most effectively engages readers by shocking them much like ‘Terminator II’. While ‘Terminator II’ looks at humanity’s ironic destructive nature and dangerous over reliance on technology, ‘Examination Day’ focuses on humanity’s often gullible and negligent over reliance on powerful forces such as the government. While both texts are strongly driven by the relevant and powerful social comments, both texts follow the conventions of sci-fi through their mutual futuristic settings, advanced technology as well as the utilisation of other genres within; specifically the thriller genre. Along with powerful film and literary techniques, both texts entertain audiences.
