MiG-17 Fresco Soviet Fighter

MiG-17 Fresco Soviet Fighter With the introduction of the successful MiG-15 in 1949, the Soviet Union pressed forward with designs for a follow-on aircraft. Designers at Mikoyan-Gurevich began modifying the earlier aircrafts form to increase performance and handling. Among the changes that were made was the introduction of a compound swept wing which was set at a 45 ° angle near the fuselage and 42 ° farther outboard. In addition, the wing was thinner than the MiG-15 and the tail structure altered to improve stability at high speeds. For power, the MiG-17 relied on the older aircrafts Klimov VK-1 engine. First taking to the sky on January 14, 1950, with Ivan Ivashchenko at the controls, the prototype was lost two months later in a crash. Dubbed the SI, testing continued with additional prototypes for the next year and a half. A second interceptor variant, the SP-2, was also developed and featured the Izumrud-1 (RP-1) radar. Full-scale production of the MiG-17 began in August 1951 and the type received the NATO reporting name Fresco. As with its predecessor, the MiG-17 was armed with two 23 mm cannon and one 37 mm cannon mounted under the nose.

These were equipped with the Klimov VK-1F engine which featured an afterburner and significantly improved the MiG-17s performance. As a result, this became the most produced type of the aircraft. Three years later, a small number of aircraft were converted to MiG-17PM and utilized the Kaliningrad K-5 air-to-air missile. While most MiG-17 variants possessed external hardpoints for around 1,100 lbs. in bombs, they were typically used for drop tanks. As production progressed in the USSR, they issued a license to their Warsaw Pacy ally Poland for building the aircraft in 1955. Built by WSK-Mielec, the Polish variant of the MiG-17 was designated Lim-5. Continuing production into the 1960s, the Poles developed attack and reconnaissance variants of the type. In 1957, the Chinese began license production of the MiG-17 under the name Shenyang J-5. Further developing the aircraft, they also built radar-equipped interceptors (J-5A) and a two-seat trainer (JJ-5). Production of this last variant continued until 1986. All told, over 10,000 MiG-17s of all types were built. Operational History Though arriving too late for service in the Korean War, the MiG-17s combat debut came in the Far East when Communist Chinese aircraft engaged Nationalist Chinese F-86 Sabres over the Straits of Taiwan in 1958. The type also saw extensive service against American aircraft during the Vietnam War. First engaging a group of US F-8 Crusaders on April 3, 1965, the MiG-17 proved surprisingly effective against more advanced American strike aircraft. A nimble fighter, the MiG-17 downed 71 American aircraft during the conflict and led the American flying services to institute improved dog-fighting training. Serving in over twenty air forces worldwide, it was used by the Warsaw Pact nations for much of the 1950s and early 1960s until being replaced by the MiG-19 and MiG-21. In addition, it saw combat with the Egyptian and Syrian Air Forces during Arab-Israeli conflicts including the 1956 Suez Crisis, the Six-Day War, the Yom Kippur War, and the 1982 invasion of Lebanon. Though largely retired, the MiG-21 is still in use with some air forces including China (JJ-5), North Korea, and Tanzania.

Discussion question 2 Essay Example | Topics and Well Written Essays - 2500 words

Discussion question 2 - Essay Example Effectiveness on the other hand is concerned with achieving a stated objective. Effectiveness aims to ensure that the outcome of a process is the one that was intended when the production process was beginning. When considering effectiveness only, an organisation may explore different ways of achieving the end result. Effectiveness alone may not be enough in regards to the limited resources with which organisations have to work with therefore a balance between efficiency and effectiveness needs to be achieved so that after the production process, the organisation has not only achieved the main goal ,but it has also used a cost effective efficient process. Management can improve both efficiency and effectiveness simultaneously though the maximum benefits may not be achieved immediately. Efficiency could be improved by creating a conducive working environment for workers. This may include allowing flexible working hours. This way workers who are more productive in the mornings work in the morning while those who are more productive late at night work then.By allowing workers flexibility in their working, they end up being more efficient. Identifying workplace processes and mapping them helps determine if there are any unnecessary or redundant processes interfering with workplace efficiency. If such processes are eliminated or done away with efficiency is greatly improved (Kejz?ar 728). Embracing new technologies for example use of I pads in businesses increases computing flexibility and portability, greatly improves efficiency. Another way of improving efficiency at workplace is by encouraging teamwork among employees. This enables them to communicate more effectively .For instance if they are involved in teamwork activities outside the workplace as in a teambuilding retreat they are more likely to carry the lessons learnt back to the workplace .This way processes become become more efficient and the main objective of the organization is met thus both efficiency and effectiveness can be improved simultaneously Societal factors are external forces or factors emerging from changes and trends in the society that have impacts on organizations beyond their control. They include social cultural factors, legal factors technological advancements and international factors such as the global recession. Societal factors affect the theory and practice of management in various ways .For instance, current trends and attitudes are having a huge impact on how organisations and businesses are managed .Development of internet has led to many organisations turning to the world of online marketing and advertisements to enable them reach a broader range of clients. Many high street organisations are capitalizing on the popularity of the worldwide web to come up with exclusive online ranges of their products and goods. Changes in the society are resulting in organisations allowing a proportion of their employees, some with young children and others who have hect ic schedules to work from home (Kejz?ar 524). This way the employees who are not able to work from the office are not lost thus the employer does not have to look for new employees who might need training and take time before they become as efficient as the previous

Stereotypes and Prejudice Worksheet Essay Example for Free

Stereotypes and Prejudice Worksheet Essay Please complete the following exercises, remembering that you are in an academic setting and should remain unbiased, considerate, and professional when completing this worksheet. Part I Select three of the identity categories below and name or describe at least 3 related stereotypes for each: †¢Race †¢Ethnicity †¢Religion †¢Gender †¢Sexual orientation †¢Age †¢Disability Category Stereotype 1 Stereotype 2 Stereotype 3 Age Old people are slow Young people are trouble makers Young people are lazy Gender Men work harder than women Women should do all house work Women have more feelings than men. Race Black people are better at sports Asians are smart White people get better jobs Part II Answer each question in 50 to 100 words related to those stereotypes. Provide citations for all the sources you use. What are the positive aspects of stereotypes, if any? One benefit of stereotypes to those being stereotyped is that the stereotype itself may be positive. Of course, this can backfire if you benefit from a stereotype of a group in which you fit and it becomes clear that the stereotype does not apply to you. One example of a positive stereotype is that Asians are good at math. Another example of a positive stereotype is that Jewish people are good with money. What are the negative aspects of stereotypes? By stereotyping we infer that a person has a whole range of characteristics and abilities that we assume all members of that group have. Stereotypes lead to social categorization, which is one of the reasons for prejudice attitudes. Most stereotypes probably tend to convey a negative impression. Part III Copyright  © 2012 by University of Phoenix. All rights reserved. Stereotypes and Prejudice Worksheet ETH/125 Version 8. 2 Answer each question in 50 to 150 words related to those stereotypes. Provide citations for all the sources you use. Define stereotypes and prejudice. What is the difference between stereotyping and prejudice? Use examples to illustrate the differences. Stereotypes are assumed characteristics. They do not have to carry a moral judgment (although many time they do). Example: The French like good cooking. Or, Icelanders dont mind the cold. Prejudice is preferring one kind of person over another. It may be based on stereotypes (I dont like Jews because theyre cheap), or not (I dont like Irish people because an Irish kid beat me up long ago). What is the relationship between stereotyping and prejudice? The relationship is that one is having the wrong impression of the person before meeting them, the other is GUESSING that they are all the exact same as the one, or two, that you have met. They are both assuming things about someone and judging someone based on the difference in them. It is either from experience or from what you heard but either way it is a judgement before you meet them or after. What can be done to prevent prejudice from occurring? Let schools teach children that all people are equal regardless of race, gender, orientation, etc, let governments introduce laws that explicitly promote equality for all. But I think first of all it starts at home. I think if we teach our children that no matter what we are all equal and treat each other with respect. I think that if we all did this and showed them as also as tell them, then all the judgement will die down a lot. Copyright  © 2012 by University of Phoenix. All rights reserved.

The Narcissistic Willy Loman in Death of a Salesman :: Death Salesman essays

The Narcissistic Willy Loman in Arthur Miller's Death of a Salesman    Many dilemmas throughout the recent decades are repercussions of an individual's foibles. Arthur Miller represents this problem in society within the actions of Willy Loman in his modern play Death of a Salesman. In this controversial play, Willy is a despicable hero who imposes his false value system upon his family and himself because of his own rueful nature, which is akin to an everyman. This personality was described by Arthur Miller himself who "Believe[s] that the common man is as apt a subject for a tragedy in its highest sense as kings were" (Tragedy 1). An additional segment of his common human nature is Willy's self-centeredness. Although one might say that the American Dream is imposed upon him by the society, Willy himself creates his dream. Willy supports this claim when he praises Dave Singleman's career to Howard: "And when I saw that, I realized that selling was the greatest career a man could want" (Miller 81). His nostalgia for a non-existing future is also proven by the fact that no one else in his environment has a similar, impossible dream: "If he were not wearing the rose colored glasses of the myth of the American Dream, he would see that Charley and his son are successful because of lifelong hard work and not because of the illusions of social popularity and physical appearances" (Spark 11). Surely the false ego and pride predicted to come from his assured success are the bridges that prevents Willy from seeing through his fake dream, pushing him to persuade the rest of his family to worship it along with him. Biff sadly bites the apple when he realizes his fate: Willy! I ran down eleven flights with a pen in my hand today. And suddenly I stopped, do you hear me? And in the middle of that building and I saw--the sky. I saw the things that I love in this world. The work and the food and the time to sit and smoke. And I looked at the pen and said to myself, what the hell am I grabbing this for? Why am I trying to become what I don't want to be?

A Persuasive Essay About the Influence Television Has on Children

Obesity is a growing problem, and it is time for parents to step up to the plate and take responsibility for child obesity. Daniel Weintraub uses an emotional appeal, the article â€Å"The Battle Against Fast Food begins in the Home†, to mandate parents to take responsibility to protect their children against obesity. He states that even though the fast-food companies and the government contribute and influence childhood obesity, ultimately it is the parents’ responsibility for obesity in their children.He provides several good points showing how parents are the ones to take the blame for the increasing problem. I believe that parents are indeed responsible for child obesity. Weintraub makes several good points on how parents should take responsibility and avoid obesity in their children. He does this by commanding parents to teach their children good habits, especially good, healthy eating and exercise habits. Also, he states that parents should protect children agains t bad things.In this case, fast-food is considered a bad thing since it does not only make children obese but causes a variety of medical conditions as well, so parents need to step up and protect their children against fast-food. Lastly, he believes that parents need to take responsibility since they are in the best position to educate their children. According to Daniel Wientraub, â€Å"It is parents–not the government, not the fast-food companies, not the video-game manufactures–are in the best position to fight the epidemic of overweight children. As you can see Weintraub believes that there is no one to blame for childhood obesity but the parents. Weintraub makes several good points, which induces parents to take responsibility and action for the matter. Even though Weintraub makes a good argument, he has a few weak points, because his opinions are too simple when there is more to it than what he presents. For example, Weintraub does not provide any sort of stati stics, facts, or references. Also, you could argue that teachers, not parents, are in the best position to teach their children since they are well educated in the field of health and nutrition.After all, teachers are required to teach health class in school. Lastly, the whole article is just an emotional appeal in which Weintraub goes to the extremes and exaggerates. Weintraub says, â€Å"We have laws against leaving a loaded weapon where their children can find it and use it to hurt themselves or others. But no one seems to want to tell parents that they need to protect their children from unhealthy foods and from sloth. † Clearly, he exaggerates because it is almost absurd to compare the dangers of a firearm to the dangers of a french-fry.Overall, I agree with Weintraub and believe that parents are the ones responsible for childhood obesity. First of all, parents’ poor eating habits have a great influence in child obesity. Parents need to educate themselves in the n utrition field, to be able to offer a good, healthy diet and correct portion sizes to their children. Secondly, the lack of discipline by parents also contributes to obesity in their children. Parents are easily manipulated by their children, and as a result children get what they want.Parents need to make their children get some sort of exercise as well. Lastly, parents’ economic issues might lead them to buy fast-food, but fast-food is not as cheap as it seems. When you add up all the numbers it is inevitable to notice that the difference between fast-food and home cooked meals is minimum. According to a Yale survey, seventy percent of the cause to the rise in childhood obesity rests with the parents. As you can see, statistics have shown that parents are the responsible ones for obesity in children.Evidently obesity among children is a huge, dangerous problem, which parents need to take action of and help their children. It is a must for parents to teach their children abo ut proper eating habits. Disciple also influences a child’s obesity and parents need to get a bit strict with their children. Lastly, economic issues should not lead parents to buy fast-food because it is not that cheap and very unhealthy. I believe it is time to stop blaming others. Parents need to get well educated, so they can provide good eating habits and decrease the growing problem of obesity in children.

Amendment Xxi. Section 1 The Eighteenth Article Of The

Amendment XXI Section 1: The eighteenth article of the amendment to the Constitution of the United States is hereby repealed. Section 2: The transportation or importation into any State, Territory, or Possession of the United States for delivery or use therein of intoxicating liquors, in violation of the laws thereof, is hereby prohibited. Section 3: This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by conventions in the several States, as provided in the Constitution, within seven years from the date of submission hereof to the States by the Congress. Abstract Congress passed Amendment XXI in February of 1933. On 5 December 1933, Utah became the 36th state to ratify the†¦show more content†¦Some Protestant religions also pushed for an amendment because their religious beliefs prevented the use of alcohol. Through all these efforts, aided by a wave of post World War I patriotism, Amendment XVIII was passed and ratified by the end of 1919. Amendment XVIII did accomplish the goal of reducing the consumption of alcohol, but also led to several unintended consequences. The rise of organized crime, including the emergence of notorious gangster Al Capone, quickly followed the passage of the amendment. Many people, even normally law abiding citizens, were willing to break the law to consume alcohol. Speakeasies grew and flourished as men and women sought out establishments that provided alcohol. Despite passing with an overwhelming majority, opposition to Amendment XVIII arose quickly. In addition to the rise in criminal activity, many f ound ways around the law. A specific type of grape juice was sold with a U.S. Department of Agriculture warning label that if the juice were allowed to age for sixty days, it would ripen into wine with an alcoholic content of twelve percent. The Depression also contributed to opposition to the amendment. Many argued that the thousands of jobs lost were a drag on the economy, both for the employment loss and the tax revenue loss. The Democratic Party called for a recall in 1932 and the Republican party acknowledged a need to reexamine the issue.
