The World s Leader As A Global Police Force, Implementing...

America is known today for being a global police force, implementing democracy and promoting world peace. As the nation expanded, America got more and more involved in foreign affairs and policies. Whether it was wars or colonial expansion, the US was extending its hand in the affairs of other nations or regions. While we are hated in many countries, it is undoubtedly true that we are the world’s leader in peace promotion and solving global epidemics. America has evolved to be the leading disaster relief nation, as well as the most substantial supporter against terrorism. While it is hard to pinpoint, I believe America’s role in the global community should be that of a referee. What exactly does a referee do? A referee is a position in sports or contests that keeps the match within the playing rules and judges the sportsmanship of the players. In today’s world, I think the US is a little too involved in foreign affairs and wars. Ranging from the conflicts in the Middle East to the drug cartels in Central and South America, we simply are trying too hard to determine the outcome. Many people ask then; do we just leave the people there to die? Of course not. We assist, yes, but we should still make the people in the region do most of the work. Just an example, the United States of America was founded under a people who struck out with absolutely zero foreign assistance in the beginning of the revolution. By doing this, we created our own sense of nationalism that hasn’t beenShow MoreRelatedGp Essay Mainpoints24643 Words   |  99 PagesGovernment Censorship d. Profit-driven Media e. Advertising f.

Technology and education Free Essays

string(150) " men and women spent about the same amount of time on email, class assignments on the computer, playing computer games, and shopping on the Internet\." Introduction: Disability and Technology According to the U. S. Department of Commerce, more than half of all Americans use the Internet in some way, but â€Å"persons with a disability are only half as likely to have access to the Internet as those without a disability†¦ [a]nd while just under 25% of those without a disability have never used a personal computer, close to 60% of those with a disability fall into that category. We will write a custom essay sample on Technology and education or any similar topic only for you Order Now † In addition â€Å"[a]mong those with a disability, people who have impaired vision†¦ have even lower rates of Internet access and are less likely to use a computer regularly than people with hearing and mobility problems† (National Telecommunications and Information Administration, 2000, p. xv). Cyndi Rowland, director of the Web Accessibility in Mind (WebAIM) project at Utah State University’s Center for Persons with Disabilities, calls for a â€Å"national solution† to the problem of inaccessibility, especially â€Å"if we are to abide by civil rights legislation, federal rulings, and common ethics† (Rowland, 2000, p. 10). Understanding the specific needs and concerns of students with disabilities may aid educators, information technology designers, and educational institutions to ensure that students with disabilities, particularly those who are blind or visually impaired, are not left behind in this technological â€Å"revolution.† The Internet and the web have become an integral part of higher education, transforming the educational experiences of all   students. In 1997, the World Wide Web Consortium (W3C), the international body that oversees the protocols and operations of the Internet, created the Web Accessibility Initiative (WAI). WAI is responsible for promoting web functionality for people with disabilities and establishing accessibility guidelines. In this age of computer technology, many of the tools needed to enable students with disabilities to obtain equity in education and beyond already exist. For those involved in educational institutions, these tools can provide opportunities and independence, eliminating the obstacles and barriers that many of the current systems still enable. A review of the literature related to attitudes and other barriers that people with disabilities must contend with every day at school and at work, the integration of computer technology in postsecondary education, and the needs and concerns of students with disabilities, in particular those who are blind or visually impaired, may provide some insights for future policies and guidelines regarding access and use of computer technologies for students who are blind or visually impaired. Technology: Enhancing Modern Education Experiences of people with visual impairments in the workplace and their use of computer technology and the Internet was the focus of a qualitative study conducted in Australia by Williamson, Albrecht, Schauder, and Bow (2001). Primarily through focus group research, the researchers presented the perceived benefits and concerns of the study’s participants. Most agreed that the Internet enabled them to participate in an information and communication format that is becoming a primary source for many people. Many also saw the Internet as enabling them to be less reliant on others and, therefore, facilitating an increase in their own privacy. However, some were concerned about a reduction in social contact and an increase in isolationism. An additional concern was that there would be a decline in the quality of services from such entities as the government and banks because more is being done online. Training was viewed as critical to successfully using the Internet and computer technology. This, it was believed by many, was the key to achieving equality in the workplace, yet many felt it was a low priority by agencies and workplaces. Cost was also viewed as a barrier to accessing computers and the Internet. With various Internet advances, more individuals in all sectors of the community are working from home.   For visually impaired members of community the Internet has the potential to free them from the restrictions they have experienced in the past while seeking to obtain employment. â€Å"Once the challenges of access have been surmounted, [visually impaired] users can take their places in the digitalized workforce† (Williamson et al., 2001, pp. 693-4). With computer technology becoming a part of all college students’ educational experiences, how are postsecondary schools preparing students for a computer-integrated future? To determine how the use of various technologies affect student learning, Shuell and Farber (2001) conducted a study of 728 sighted undergraduate and graduate students at a large northeastern university, where they found that, in general, students perceived the use of computer technology in their courses to be very beneficial. Students also believed that the use of communication technology brought an increase in their sense of involvement in a course. Eighty-eight percent of the sample indicated that their use of computer technology helped them learn materials and skills, and 75 percent indicated that using computer technology improved the quality of interaction with their instructor. Students also viewed the use of dynamic computer presentations and the Internet in lectures very favorably; it kept their interest, and the students believed that it improved their learning.  Ã‚  Ã‚   Students also favored electronic forums as a way to interact with their peers (e.g., email, listservs, and newsgroups) and believed that the use of these forms of computer technology increased the quality of these interactions. Another interesting finding in this study was that students who considered themselves to be more independent tended to respond more favorably to these technologies and the learning benefits associated with them. One theme of this study was the appreciation that students had of the ability for computer technologies to enable independent learning. When serving the needs of students with disabilities, independence is a key factor to consider. Lewis, Coursol, and Khan (2001) examined the use and effect of computer technology on student development and education. They surveyed 124 sighted undergraduate students who attended a regional public institution in the Midwest. Technology choices, which included use of email, the Internet, and multimedia, were based on technology trends in higher education. Results indicated that the majority of students were comfortable with computer technology, using such tools as email and the Internet for both academic and social purposes. Both men and women spent about the same amount of time on email, class assignments on the computer, playing computer games, and shopping on the Internet. You read "Technology and education" in category "Essay examples" However, women spent significantly fewer hours surfing the Internet than men did. Consistent with Shuell and Farber (2001), Lewis et al. (2001) also confirmed that students believe the use of email increases their frequency of communication with faculty, which, in turn, enhances the faculty-student relationship and enables faculty to be more accessible. The issue of accessibility was discussed in this report and how there is a need for higher educational institutions to address this issue, which the authors indicate to be a social problem that has significant economic and social implications. They point to the need to recognize that there are some students, including those with disabilities, who may be at a disadvantage when a course requires the retrieval of materials from the web. The use of computer technology has become an accepted and expected component of every student’s postsecondary educational experience. To better understand the use and effectiveness of these technologies, all of the studies used in this paper that focused on computer technology in higher education examined one or more aspects of the integration of these technologies into the educational system. The Arant (1996) study focused on the use of the Internet and the World Wide Web in higher education. Employing both qualitative and quantitative methods (phone interviews and a survey), it concluded that, while using online components to traditional courses did not support the apparent belief that online education saved time and money, it did change the way in which courses were taught, with additional online portions being incorporated into courses. For students who are visually impaired or blind, this could result in additional barriers. Computer Technology and Visually Impaired Students In an extensive two-year study in Canada, Fichten, Barile, and Asuncion (1999) investigated the computer, information, learning, and adaptive technology needs and concerns of Canadian postsecondary students with disabilities. Of the findings from this study, computers were found to be critical to the success of students with disabilities, and the vast majority of students, regardless of gender, age, program of study, or type of disability, could and did use computer technologies to help them succeed. An important development that emerged from this study was that students often â€Å"cross-used† technologies. For example, while students with visual impairments are expected to use screen reader software, students with learning disabilities also used this software. The students in this study considered computers as â€Å"electronic curb cuts,† enabling technologies that allow students with disabilities to better prepare for and participate in the information-based economy of tomorrow. Fichten, et al. (1999) urged postsecondary education institutions to design for accessibility and to consider the needs of students with disabilities before making purchases.   What the authors describe as â€Å"troubling† is â€Å"the absence, in many cases, of planning for access† for students with disabilities by postsecondary institutions (Fichten et al., p. 179).   As some technological barriers fall, others are slowly erected as new technologies continue to become part of a student’s educational experiences. One suggestion the authors had for government funding bodies to help raise awareness of these issues was to take accessibility issues into consideration when reviewing grant applications and to create incentives for businesses to develop and market technologies that are accessible to all students. The authors wrote: The enormous potential of computers to remove barriers to students with disabilities and concerns over barriers posed by limitations in access were central issues noted by respondents in all categories in all phases of the research (p. 180). Shaw and Giacquinta (2000) used a questionnaire that was very carefully developed, field tested, and revised several times before being used for this study. The sample consisted of 412 sighted graduate students. This study was very well thought out and documented.  Ã‚   The authors suggested that faculty integrate more computer technology into their curricula (e.g., with the use of such tools as Blackboard, WebCT, and course web pages). They did not, however, take into consideration the ramifications of that suggestion as it applies to students who are blind or visually impaired.  Ã‚   Unfortunately, unless having been asked to consider it, most faculty do not think about students who are blind or visually impaired (or who have any other disability) when they begin to integrate technology into their curriculum. Shuell and Farber (2001) piloted a questionnaire and discussed it within two focus groups before using it for the study. Their sample was composed of 728 sighted undergraduate and graduate students.  Ã‚   Both qualitative and quantitative data showed a link between active, participatory learning and the positive perception of students regarding technology as a learning tool; they also confirmed that the use of technology made the classes seem more personal to the students. However, the authors caution that the apparent relationship found in their study between a positive perception of computer technology by students and students’ actual learning is still unclear. Lewis et al. (2001) used an author-constructed survey, which they described as â€Å"a self-report, forced-choice survey.† One of the problems with this study is that a self-report is subject to response bias, although the results of this study were consistent with the others regarding a positive perception and use of computer technology by students in postsecondary institutions. Both Shuell et al. and Lewis et al. recommended that future research focus on the impact of technology on student learning. Lewis et al. also recommended the need to examine the use of technology among specific groups, such as students who are Hispanic, African American, and commuters. Conclusion Given the state of existing literature in the area of postsecondary students who are blind or visually impaired, combined with the overwhelming integration of computer technology into the academic environment, there is still a need for a more substantive exploration into how postsecondary institutions are supporting and serving the best interests of these students. Disability scholars Susan R. Jones and Julie Smart point out the relationship between individuals who have a disability and how society views people with disabilities. They assert that disability is a universal issue, and yet there is no single disability experience. With a focus on the prejudices, discrimination and stigma experienced by people with disabilities and their responses to their disabilities, Jones (1996) and Smart (2001) define disability as a socially constructed phenomenon that combines the experiences of those living with a disability together with their environments. Goggin and Newell (2003) further state that â€Å"in the name of inclusion† society builds disability into digital technologies, arguing that disability has been constructed in the technological world of computing and computer networks and that there is a need to critically analyze the ways in which it is constructed within contemporary society.

The Australian Exchange Rate Essay Example For Students

The Australian Exchange Rate Essay The Australian Exchange RateBy: Dontae SmithIntroduction: What factors affect the demand and supply of Australian dollars in the foreign exchange markets? Distinguish between the possible causes and effects of currency depreciation and a currency appreciation on the Australian economy. What forces have come into play, if any, in the past four months that have affected the value of the Australian dollar?Exchange Rate: The rate at which one unit of domestic currency is exchanged for a given amount of foreign currency A BRIEF HISTORY OF THE AUSTRALIAN DOLLARUntil 1971, the Australian dollar (AUD) was pegged to the British pound. This meant that the AUD rose or fell in line with the pound. In 1971, the AUD became pegged to the US dollar instead. These currencies were fixed currencies, which meant that the Australian currency would only change value when a major world currency also changed. This system lasted only until 1974 when the AUD became pegged to a trade-weighted selection of other currencies. This was still a fixed currency. In 1976 this selection of currencies became moveable. Small shifts were able to take place when needed. In 1983 the AUD became a floating currency. This means that the value of the dollar is determined by supply and demand. Initially, the Reserve Bank of Australia was not intended to intervene in the market however since then it has been deemed necessary for intervention to take place, usually to prop up the price. FACTORS AFFECTING SUPPLY AND DEMAND OF AUSTRALIAN DOLLARSWith a floating exchange rate, such as Australias, supply and demand factors largely determine the dollars equilibrium price. The exchange rate is sensitive to changes in both demand and supply, which can cause changes in the equilibrium exchange rate. Another factor, which can affect the supply and demand of Australian dollars, is intervention in the market by the Reserve Bank of Australia. DEMANDThe demand for Australias currency in the foreign exchange market (Forex) is a derived demand. It is derived from the demand for a countrys exports of goods and services and its assets. In simple terms, people who may have a demand for the Australian dollar could include: _ Foreigners wanting to purchase Australian exports _ International tourists visiting Australia _ International investors wishing to purchase Australian shares or property _ International firms setting up branches or expanding in Australia _ Speculators and investors who think the value of the Australian dollar will rise in hope of making a profit. The demand for the Australian dollar will be affected by a number of factors. These factors are: The Size of financial flows into Australia The size of financial flows into Australia from investors who wish to invest in Australia and need to convert their currency into AUD will affect demand for the dollar. The level of Australian interest rates relative to overseas interest rates as well as the level of confidence in the Australian economy will affect the level of capital inflow. If Australia has relatively higher interest rates and stronger confidence, then this will encourage capital inflow and increase demand for the AUD. Using this theory, the Australian dollar at the present looks to be in a relatively strong position. Interest rates are beginning to rise (official interest rate has recently been risen 0.25 points to 4.5% and is expected to raise to 5.25% by September this year, with economic growth expected to be around 3. 75% in 2002/03.) Also increasing the confidence in future economic growth is the recent budget. The 2002/03 budget released on 14th May 2002 was a deficit budget. This means that the government has spent more than it has earned. .u7727a2f1f41a51c17fbcef1efa18f6b8 , .u7727a2f1f41a51c17fbcef1efa18f6b8 .postImageUrl , .u7727a2f1f41a51c17fbcef1efa18f6b8 .centered-text-area { min-height: 80px; position: relative; } .u7727a2f1f41a51c17fbcef1efa18f6b8 , .u7727a2f1f41a51c17fbcef1efa18f6b8:hover , .u7727a2f1f41a51c17fbcef1efa18f6b8:visited , .u7727a2f1f41a51c17fbcef1efa18f6b8:active { border:0!important; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .clearfix:after { content: ""; display: table; clear: both; } .u7727a2f1f41a51c17fbcef1efa18f6b8 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u7727a2f1f41a51c17fbcef1efa18f6b8:active , .u7727a2f1f41a51c17fbcef1efa18f6b8:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .centered-text-area { width: 100%; position: relative ; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u7727a2f1f41a51c17fbcef1efa18f6b8:hover .ctaButton { background-color: #34495E!important; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u7727a2f1f41a51c17fbcef1efa18f6b8 .u7727a2f1f41a51c17fbcef1efa18f6b8-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u7727a2f1f41a51c17fbcef1efa18f6b8:after { content: ""; display: block; clear: both; } READ: Some Neo-Freudian Views On A Serial Killer Essay This is an injection of money into the Australian economy and will stimulate economic activity and growth.

The Future of Human Computer Interface and Interactions

Introduction The society today has completely changed due to technology. Technology is changing at a very rapid rate and with the changes come the need to adapt to them. Computer has changed the way human being does his activities (Beaureau 2008, p.36). Unlike before when most of the activities were done manually, computer has enabled automation of most of activities, especially in large companies.Advertising We will write a custom essay sample on The Future of Human Computer Interface and Interactions specifically for you for only $16.05 $11/page Learn More It is now possible for a manager to monitor activities taking place in a different company’s branch from where he or she is by use of computerized gadgets. Management and other duties have been redefined by introduction of the modern day gadgets that are computer controlled. The Future of Human Computer Interface and Interactions Human Computer Interface refers to the interactivity between com puter and people (Sutherland, Robertson and John 2009, p.49). Unlike other gadgets that do not communicate with the user, computer is the only tool that will have a direct communication with the user. This interactivity is made possible by both the software and the hardware. The user passes the communication by use hardware like mouse and keyboard and receives the communication through characters displayed on monitor, or through sound. However, this method of communication is only reliable to people who are not handicapped. People without hands and those that are mentally handicapped may not be in a position to operate the traditional computers properly (Rodgers and Streluk 2002, p.98). However, this may be changing very soon. Dr. Eric Leuthardt and a group of other scientist have developed a new computer interface that would accommodate the physically handicapped. This interface allows one to control the computer using the brain. The computer is programmed to read the mind and resp ond to the demands of that mind. By using the power of their thought, these physically handicapped individuals are able to control the cursor to issue commands to the computer.

A group of Australian scientist has come with a new invention that is very similar to that of iPad. It has the ability to read anything placed on it.

I t can also be of good use in places like supermarkets in the billing section. The future of human computer interface and interactivity is already here. Life is becoming easier with every technological invention. This has a positive impact both in the short and long run, especially in the field of entertainment and digital divide. Human being will also be able to delegate much of his duties to computers. A keener look into this phenomenon will reveal that in as much as these inventions are necessary and that they have positive impact on mankind, it is also true that they come at a cost. The effect of these sophisticated machines on the environment is adverse, especially when poorly disposed (Abbot 2001, p.79).
