A Technical Analysis of Ergonomics and Human Factors in Modern Flight D

I. Introduction Since the dawn of the aviation era, cockpit design has become increasingly complicated owing to the advent of new technologies enabling aircraft to fly farther and faster more efficiently than ever before. With greater workloads imposed on pilots as fleets modernize, the reality of he or she exceeding the workload limit has become manifest. Because of the unpredictable nature of man, this problem is impossible to eliminate completely. However, the instances of occurrence can be drastically reduced by examining the nature of man, how he operates in the cockpit, and what must be done by engineers to design a system in which man and machine are ideally interfaced. The latter point involves an in-depth analysis of system design with an emphasis on human factors, biomechanics, cockpit controls, and display systems. By analyzing these components of cockpit design, and determining which variables of each will yield the lowest errors, a system can be designed in which the Liveware-Hardware interface can promote safety and reduce mishap frequency. II. The History Of Human Factors in Cockpit Design The history of cockpit design can be traced as far back as the first balloon flights, where a barometer was used to measure altitude. The Wright brothers incorporated a string attached to the aircraft to indicate slips and skids (Hawkins, 241). However, the first real efforts towards human factors implementation in cockpit design began in the early 1930's. During this time, the United States Postal Service began flying aircraft in all-weather missions (Kane, 4:9). The greater reliance on instrumentation raised the question of where to put each display and control. However, not much attention was being focused on this area as engineers cared more about getting the instrument in the cockpit, than about how it would interface with the pilot (Sanders & McCormick, 739). In the mid- to late 1930's, the development of the first gyroscopic instruments forced engineers to make their first major human factors-related decision. Rudimentary situation indicators raised concern about whether the displays should reflect the view as seen from inside the cockpit, having the horizon move behind a fixed miniature airplane, or as it would be seen from outside the aircraft. Until the end of World War I, aircraft were manufactured .. ...anifest. The discussion of biomechanics in chapter three was purposely broad, because it is such a wide and diverse field. The concepts touched upon indicate the areas of concern that a designer must address before creating a cockpit that is ergonomically friendly in the physical sense. Controls and displays hold a little more relevance, because they are the fundamental control and feedback devices involved in controlling the aircraft. These were discussed in greater detail because many of those concepts never reach the conscious mind of the operator. Although awareness of these factors is not critical to safe aircraft operation, they do play a vital role in the subconscious mind of the pilot during critical operational phases under high stress. Because of the unpredictable nature of man, it would be foolish to assume a zero tolerance environment to potential errors like these, but further investigation into the design process, biomechanics, control and display devices may yield greater insight as far as causal factors is concerned. Armed with this knowledge, engineers can set out to build aircraft not only to transport people and material, but also to save lives.

The Importance of Point of View in Kate Chopin’s Fiction Essay

The Importance of Point of View in Kate Chopin’s Fiction The impact of Kate Chopin’s novel, The Awakening, on society resulted in her ruin, both literary and social. Reviewers called it vulgar, improper, unhealthy, and sickening. One critic said that he wished she had never written it, and another wrote that to truly describe the novel would entail language not fit for publication (Stipe 16). The overwhelming condemnation of the entire book rather than just Edna’s suicide seems surprising in light of her successful short story career. The themes that Chopin explores in her novel are present in both Bayou Folk and A Night in Acadie, her short story collections published before The Awakening, and the other short stories she published separately. The only reasonable explanation is that people misinterpreted Chopin’s short stories about male/female relationships as sentimental and witty stories rather than serious condemnations of the social order that left women so little choice while giving men little restr iction. This misinterpretation even occurs today. In classes I have taken that cover Chopin, many students and instructors read her short stories as romance, as celebrations of motherhood, and as empowerment of the matriarchy, yet they read The Awakening and recognize Chopin’s criticism of society without seeing any serious contradiction in their earlier readings of her short stories. However, the overwhelming pattern in Chopin’s fiction seems to either satirize or undermine the worlds of her characters. One way in which she does this is through point of view. A look at this technique reveals the genesis of The Awakening in even the earliest of her published fiction dealing with male/female sexual relationsh... ...man Writer in the South: 1859-1936. Baton Rouge: Louisiana State UP, 1981. Le Marquand, Jane. â€Å"Kate Chopin as Feminist: Subverting the French Androcentric Influence.† Deep South 2 (1996). 26 July 2002 . Stipe, Stormy. â€Å"The Book That Ruined Kate Chopin's Career.† Biblio 4.1 (1999): 16-17. Notes [1] Patricia Evans notes in a discussion of Chopin’s place in the literary canon that â€Å"in the first modern historical survey of southern literature, The South in American Literature, Jay B. Hubbell identifies one hundred male writers, but only five women. He justifies this omission by stating, ‘their writing was generally sentimental and inferior’ (4).† [2] In The Awakening, Robert LeBrun turns way from Edna when she proposes they live openly together. He cannot violate the codes of his world so blatantly.

Singapore’s Political, Economic, and Social

I will be conducting my research paper Singapore Political, Economic, and Social Organization. The method that I will use to gather my information will be ethnology. Ethnology is Comparative study of cultures with the aim of presenting analytical generalizations within the context of that society. Singapore is a postindustrial society that has a parliamentary republic with a Westminster system of unicameral parliamentary government representing Constitution. Singapore officially gaining sovereignty in 1965, its politics has been dominated by the People’s Action Party (PAP). Singapore, under the leadership of the PAP, possesses a distinct political culture: authoritarian, pragmatic, rational and legalistic. PAP leadership consisted of English lawyers and Chinese pro-communist trade union leaders. Unlike the western country (United States) that is run by politicians, Singapore is not run by politicians, but by a social system that where power is gained through skills, performances, and loyalty to the nation and not by politician’s policies. Singapore as has supremacy of government-controlled companies not like their western country counterparts. The reason why PAP stayed in power is due to popular support won by economic growth. Singapore raised public awareness, and stimulates public interest and debate, in economic issues is a factor of economic growth. Economic performance of Singapore depends on its mode of economic organization, natural resources, climate, and history. Singapore witnessed the unexpected economic development of vast potential for tin, rubber, oil palm, and tobacco, for Singapore is one of the largest ports in the world. Singapore is a postindustrial society where the government has invested billions in infrastructure and aims to recruit the best researchers in all modern fields of technological endeavor (Nowak & Laird, 2010). This brought immigrate from the Philippines, Indonesia, and Southeast Asia to Singapore for work. By 2006, there were approximately 580,000 lower–skilled foreign workers and 90,000 skilled foreign workers in Singapore (Yeoh, 2007). In addition, 60 percent of Singapore's factory workers are Malaysian citizens, who cross the shared border daily (Nowak & Laird, 2010). Unlike the westerner country, Singapore required that workers must take a pregnancy test and STD test regularly. Again Singapore isn’t like their westerner counterparts when it comes to unemployment. Unemployed workers must return to their home country after a short period of job hunting.

Personal narrative essay Essay

â€Å"Don’t Blink† Four hundred and eighty three people, stuck together like glue for the past four years. We all felt as if the day would never come, like seeing it cloud up but never getting any rain, like getting snow on the ground and no snow day. What some people complained about and dreaded going to was something I had grown to enjoy and tend to miss now. After spending four short years in the same routine, going to the same place, seeing my same close friends every day I really learned to enjoy what is happening because it seems like it is there and gone. To me it was really one of those things you could say â€Å"don’t blink because you might miss it.† My first day of high school wasn’t one of those days that hit me as being scary. Although there were many new people, a much bigger building, and only a few friends you could talk to from junior high. For some reason you just really feel a jump in your ego when you walk through those doors. Trying to find a new class room in five minutes was about the hardest thing that day, although as mean as some of them looked, all you had to do was ask an upper classman and you would know right where to go. I was able to make many new friends in high school. Some of them lasting a couple weeks, some maybe through that year, and a few that are still close friends today. Once in my sophomore year I realized that best friends do actually exist. After meeting him in football we started doing everything together. Having somebody to go to and talk with throughout high school was probably the biggest help of all. The years seemed to be flying by, it felt as if the days couldn’t get any longer, but the year itself would be there and gone. My friends and I were growing closer and closer as the weeks went by joining clubs and playing sports just because one another were in them. After sophomore year we all started getting our licenses this was the coolest thing ever, we got the feeling of being free, cruising around together after school and on weekends. Now, half way through the summer leading to our junior year, I had just turned 16. To me this was one of the biggest years of school. I had met some of the best people in my life that are still in it today. I was still hanging out with some really close friends, made another good friend that moved in by me, and found that high school sweet heart, well for that year at least. Finally the big year for me, coming into my senior year and I was already beginning to think about all the friends I wasn’t going to see after that one short year was over. It was getting hard watching everybody pick out a college or university and knowing that we were all going to moving away way to soon. I had joined a work program to give me half days so that I could now afford to drive my truck. Only going to school for five hours a day was making the time really fly by. I was so ready to get through one thing this year though. For the past three years I had been to play with the school band for the upper classes, but finally it was my turn to hear the music. May 20th, 2012. One of the most impacting days of my whole life. I was finally here, we made it. After a long morning of preparation, deciding on the right outfit and taking hundreds of pictures we were finally on our drive there. As our name cards were passed out we lined up next to our closes friends. The one major time I have felt this feeling, we came through a curtain and entered the biggest room I’ve ever seen packed full of cheering parents, finally it was here, graduation. It had come and gone so fast leading me through some of the best life lessons and bringing me to some of my best friends. It seemed like those few hours we were all cracking jokes and trying to laugh just to cover up our real emotions, at least I know I was, after entering this room I was really starting to realize how much I would miss all these people. It came time for me to move away. With my parents and best friend by my side to support me and help me off to college I was finally on my way. High school was now gone and college was here to offer its eye opener, much more homework, many more papers, and much more effort required. It was time for me to learn how to live on my own and support myself. I can’t say this has been one of the easiest tasks to overcome, just getting past the fact of being away from everyone I grew up with and all my close friends. I still talk to most of these people all though it will never be the same as going to school with them every day. All in that one day it was there and gone, I’m glad I didn’t blink because I just might have missed it.

History of civilization Essay Example | Topics and Well Written Essays - 1500 words

History of civilization - Essay Example The predominance that is seen to characterize western civilization across the world is seen to be relatively unprecedented largely due to the fact that although many civilizations emerged before the European civilization and actually managed to radiate their influence far beyond the borders of their original homeland, these civilizations had nevertheless not managed to cast and sustain their predominance right around the globe. The successes of the European civilization are seen to be made all the more apparent when they are compared to those of some of the other civilizations that emerged before it. While these civilizations did manage to expand, they were however unable to attain global dominance. The Islam civilization for instance managed to expand from its origins in the Middle East to Affect Central Africa and Asia, it also managed to expand to the Pacific coasts of East Indies and the Atlantic Coast of Morocco, however, it was unable to obtain any permanent foothold in Europe as a result of religious opposition, in addition to this, Islamic civilization never having crossed the Atlantic to venture into the New World as it did not have access to the appropriate navigational sciences and technology to be able to accomplish this. The Eastern orthodox Christendom civilization on the other hand initially grew up in mediaeval Byzantium and was successfully carried to the Pacific by the Russians but it eve ntually succumbed to Western social and religious influences by the close of the 17th century that were not in support of Western Christianity. The ancient civilizations of Rome and Greece managed to extend their own political influence into Northern Europe where the Roman Empire is seen to have brought artistic inspiration to the Far East and India. While the Ancient India civilization manage to radiate her commerce, art and relation into the East Indies and Far East, it was however not able to successfully

The nurses'role in the prevention of healt care -associated Essay

The nurses'role in the prevention of healt care -associated - Essay Example als, and nurses. This essay seeks to explore the various roles played by nurses in preventing or reducing incidence of infections and in doing so the essay also deals with the various patient risk factors for HAIs. Patient Risk Factors for Health Care–Associated Infections It is also worthwhile to analyse the various patient risk factors for HAIs that the nurses need to address for preventing the growing incidence of infections among admitted patients. Nurses have to identify the three elements that contribute to the transmission of infection within a health care setting: â€Å"a source of infecting microorganisms, a susceptible host, and a means of transmission for the microorganism to the host† (Collins, 2008, p. 3). Very often HAIs among patients occur when they are exposed to such microorganisms as bacteria, viruses, fungi, and protozoa from other patients, healthcare professionals or visitors. Similarly, infections can also be transmitted to patients from the hospi tal environment, contaminated drugs or food, or from medical equipments and devices. Age, type of medical treatment, organ transplantations, surgical procedures, and the severity of illness are potential contributing factors for HAIs. Therefore, it is the responsibility of healthcare nurses to ensure that such microorganisms are never spread among admitted patients through direct or indirect contact, respiratory droplets, or through air. The Role of nurses in preventing healthcare associated infections Nurses have a pivotal responsibility in managing and preventing healthcare associated infections among their patients. Every hospital needs to have a competent infection prevention system and the role of the healthcare nurse is â€Å"to maintain surveillance of healthcare-associated infections throughout the hospital† (Koutoukidis, Stainton &Hughson, 2012, p. 389). For this, nurses need to be equipped with professional excellence, theoretical knowledge and practical strategies to prevent or control infections and transmission of organisms to patients admitted in their healthcare settings. Special training is to be offered to nurses regarding the latest research and practices to detect, treat and prevent infections among patients. Nurses interact directly with the patients and are better equipped to identify traces of infections and apply evidence-based procedures to reduce or prevent HAIs. Nurses can adopt a number of strategies to control infection and reduce cross-contamination among patients. These consist of using EPA-registered chemical germicides for standard cleaning and disinfection of medical equipment, training housekeeping staff with cleaning and disinfection procedures, taking precautions to prevent cross-contamination, promoting the use of disposable patient care items, and advising â€Å"families, visitors, and patients regarding the importance of hand hygiene to minimize the spread of body substance contamination† (Collins, 2008, p. 10). It is also the responsibilit
