Online Education Research Paper Example | Topics and Well Written Essays - 1250 words

Online Education - Research Paper Example the biggest segment of online education is covered by massive open online courses that provide people from all over the world with free and sometimes pre-paid online courses on multiple disciplines. These courses are collections of particular courses, previously learned by students of different universities (Mayadas, Bourne, and Bacsich 85). The professors who taught them in the universities also work for the massive open online courses’ services and read the lectures for everyone who signs up for their courses online. Massive open online courses (MOOC) are internet classes with large-scale interactive participation and public access through the Internet, so learning content is available online to any person who wants to take a course with no limit on attendance. They are structured similar to traditional higher education courses (Martin 26), in which students watch lectures, read assigned material, participate in online discussions and forums and complete quizzes and tests on the course material. Nevertheless, MOOCs try to make the online education more effective than the traditional class room methods (Kolukuluri n. pag). Further claims have been made that short videos complement the optimal attention span of students and that discussion forums provide an adequate replacement of direct teacher–student interactions, which would be considered as normal for a class delivered on campus (Glance 5). MOOCs are typically provided by higher education institutions, often in partnership with â€Å" organizers† such as Coursera, edX and Udacity, though some MOOCs are being offered directly by college or university (as Stanford does). The MOOCs’ constructions are rather similar from source to source, but let’s consider the structure of Coursera courses as an example. In the description of each course the level of required previous knowledge for its successful mastering is indicated. Many courses are available for the beginners, while other courses require the

Zemax EE Software and Programming Dissertation Example | Topics and Well Written Essays - 2750 words

Zemax EE Software and Programming - Dissertation Example Aside from investigating properties such as reflection coefficient, absorption coefficient, temperature variation, and thermal conductivity, additional theoretical estimations are made. An example is the determination of focal length, exposed effective areas, and light collection and concentration for all components. A number of designs are evaluated to examine the effect of different geometrical shapes of light pipes for refraction studies and light cups for reflection studies. Zemax software is used for a large part of this study. Therefore, this chapter details the basics of Zemax software for optical design and ray tracing. Software programs for lens design and optical studies have been of immense utility in the field of optics. Their advent has substantially simplified and enhanced our understanding of optical design and analysis. As stated by Winston, Minano, and Benitez (2005), The design of imaging optical systems is a classic ?eld of research that has achieved a high level o f development. There are on the market optical design programs that permit the numerical optimization of the design parameters, allowing us to obtain results that were unattainable with the analytical tools used before the development of computers (p. 219). Software programs are based on a number of optical principles, such as geometrical optics and ray tracing that function according to the basic laws of optics. The following sections discuss these basic principles along with an introduction to Zemax software that is used in this study. 4.2. Ray Tracing Programs and Geometrical Optics The basic tool required in designing any imaging or non-imaging optical system is geometrical optics (Winston, Minano, & Benitez, 2005). Geometrical optics is based on the universal laws of reflection, refraction, and transmission of light. The incident light on a reflective surface and the reflected light from that surface always make equal angles to the normal, and they lie on the same plane. In cas e of transmitted light, the direction of the refracted and transmitted ray changes according to Snell’s law of refraction, according to which the sine of the angle between the incident ray and the normal is in constant ratio with the sine of the angle between the refracted ray and the normal, with all three being coplanar (Winston, Minano, & Benitez). Based on these universal laws of light, the behavior of a light ray in any optical system can be predicted. Simple optical systems can be predicted manually, but complex ones require sophisticated computer programs that can easily predict the behavior of light through computerized ray tracing. Even the analysis and design of solar concentrators requires such a program. Ray tracing is the process of constructing or following the paths of light rays through an optical system consisting of refracting and reflecting surfaces (Winston, Minano, & Benitez, 2005). For instance, the transmission of a specific concentrator can be determin ed through ray tracing as follows: N rays enter a concentrator’s aperture at a ? angle of incidence at the entry aperture of the concentrator, as shown in Figure 4.1. Fig. 4.1: Ray tracing of the rays transmitted through a concentrator to determine transmission (Winston, Minano, & Benitez, 2005). After the rays are traced through the optical system, N’ rays appear from the concentrator’s exit aperture. The dimensions of the exit aperture are determined based on the required concentration ratio of the system. The remaining N and N’ rays are lost through various processes such as ray scattering. The transmission power of the system for a different angle of incidence

MANY TIMES NOVELS,MOVIES HAVE LIFE CHANGING EFFECTS ON THEIR Movie Review

MANY TIMES NOVELS,MOVIES HAVE LIFE CHANGING EFFECTS ON THEIR AUDIENCE.EXPLAIN HOW A SPECIFIC OR NOVEL HAS HAD A POSTIVE EFFECT ON YOUR LIFE - Movie Review Example Upon being released to video, and then later DVD, many stores refused to carry it for sale or rent, including Blockbuster and Walmart. It has been my experience that most people who hold an opinion of this movie hold an opinion based upon the controversy it generated rather than the content of the film itself. Since this seems a less than progressive way to form an opinion, I decided to watch it and form an opinion based on what the movie seems to be about to me. The Last Temptation of Christ has had a lasting effect upon my life not only for its content, but as a method of showing that misinformed public opinion can have a lasting and damaging effect upon works of art that extend into time and form. The protest against the film centers around the supposedly blasphemous qualities it contains, including Jesus marrying and having children. Indeed, the film does feature a section in which Jesus marries and has children. But far from being blasphemous, these scenes highlight Jesus' sacred qualities because they take place within a vision-His last temptation on the cross. The point of the movie is that Jesus denies the temptation and accepts his mission as messiah. In other words, Jesus is heroic! Far from being blasphemous, the film is actually quite conservative in its adherence to religious dogma.

Information Technology Outsourcing in Airlines Essay

Information Technology Outsourcing in Airlines - Essay Example The changing IT environment at overseas branches and operations of firms has such a big impact on the IT related decision making process. Airlines have increasingly been attracted to IT outsourcing companies mostly based in India. Airlines can be regarded as institutions that strive to provide their customers with safety and service quality by making use of certain kinds of IT in their activities. While big airlines have been making use of IT as the main investment related strategic policy alternative, smaller airlines like budget airlines too have been making use of it in order to achieve positive synergies in IT. However while the former have been able to increase their net investment expenditure on IT on a larger scale, the latter have only been able to increase IT related investment on a smaller scale. As a result a clear dichotomy between the two entities can be noticed. Larger airlines have adopted growth oriented information and communication technology (ICT) policy measures primarily with the intention of enhancing growth drivers such as merger and acquisition (M&A) related synergies while smaller organizations have basically relied on capturing niche market segments. IT outsourcing theories are many in number though very few of them successfully capture the essence of the growth pattern of this industry. The impact of IT outsourcing on global airlines has attracted the attention of many researchers and analysts. Particularly in modern industry situations such strategies have become more relevant against the backdrop of rapid competitive and changing environment. The available literature on the impact of IT outsourcing on airlines' corporate strategies suggests different analytical and conceptual frameworks based on modern IT investment programs that are already being put into practice at some big airlines across the world. As the available literature on the subject suggests there is a substantial amount of empirical evidence to support the ICT related operations and their positive impact on growth drivers such as revenues, profits, market share, share price and integration across a number of market segments without truncation at airlines (Glaser, 2002). Independent analysts have identified three forces that determine the ultimate growth prospects of companies. (a). Differences in the local business environmentThe application of processes and procedures in identifying differences in the local business environment is connected with the overall global business strategy of the firm. ICT is a single aspect of this global strategy. If the firm were unable to identify and isolate the important elements in the global operational environment, there would be much less of an opportunity for the

Anorexia in the Fashion Industry Research Paper Example | Topics and Well Written Essays - 500 words

Anorexia in the Fashion Industry - Research Paper Example The voluptuous curves which used to be admired in the past have been switched to straighter angles and lines on fashion model’s bodies. With these skinny fashion models gracing the covers of the most exclusive and trendy magazines, many teenage girls seem to be drawn to the idea that in order for them to be as beautiful and as accepted as these models, they have to look like them. This obsession has even created the psychological disorder known as anorexia nervosa. Anorexia is a life-threatening disease, which mostly involves the act of starving oneself in order to look as thin and as â€Å"beautiful† as the fashion models. Deaths have been reported for some anorexic teenagers and models, as the unacceptable image that these models and teenagers see in their mirrors never seems to reach acceptable standards. This paper shall now investigate how the fashion world and designers influence models and girls to become extremely thin, and how they cause these girls to be anorexic. It will also note the lengths to which these girls go to in order to be and to stay as thin as possible and the impact on these girls lives. This paper shall also discuss the changing trends surrounding weight issues and fashion modeling -- from the earliest days when such trends made an impact on the world and on contemporary times. This discussion shall cover opinions and scholarly studies conducted on the subject matter, focusing on the thin fashion models and celebrities and the impact of the skinny obsession on teenagers and on girls in general. The end of the First World War brought about the raising of the hems and the lowering of the waists in women’s fashion. Panati (p. 235) points out how the dresses designed in the 1920s called for women to be flat-chested and boyish, and those who had fuller breasts were also forced to bind their chest to flatten their chests.

Economics Essay Example | Topics and Well Written Essays - 2000 words - 16

Economics - Essay Example The UK economy has undergone through very critical evolutionary steps in the 1980s through the implementation of Gower report and the enactment of the subsequent 1986 financial services act (Ellwood, 2002, 565-594). It is acknowledged that these changes are responsible of many developments that the economy has had throughout the late 20th century and the subsequent years in 21st century. This paper therefore focuses on analyzing the critical role that financial services sector play within the UK economy after the Gower report and the financial services act in the late 20th century and subsequent enactment of FSAct in 1986. The Gower report established a platform through which the UK financial sector can provide insights, financial services as well as advise to investors both locally and at the international front. The financial sector specializes in services such as finance and accountancy, banking, financial planning, insurance as well as pension and investments. Over the years that followed the 1980 Gower report, the United Kingdom has moved from the state of passive sale and display of manufacturing produce to become a leading determiner of what is manufactured as well as consumed. The financial services sector shifted the attention of services provide towards retailing and wholesaling industries within the country. Moreover the enactment of the 1986 financial act has been pointed out to have contributed towards increased regulation and compliance requirements within the sector (Llewellyn, 1999, p. 309-316). The importance of such regulation cannot be overlooked as it has the main aim geared toward s consumer protection. Through the act, the industry has been streamlined towards effectiveness in service delivery through overcoming information asymmetry between the service providers and the customers. The importance in regulation is also based on the reason that many institutions are

Nursing journals Essay Example | Topics and Well Written Essays - 250 words

Nursing journals - Essay Example ical inactivity, and associated medical conditions, as well as medication, are some of the key factors the journal identifies to be a contributor to obesity. The association between obesity and the occurrence of cardiovascular condition is the primary reason for effective management of obesity in accordance to the journal (Nieswiadomy, 2012). In consideration of the prior knowledge concerning obesity and cardiovascular conditions, I find the journal among the greatest works that exclusively covers the topic of obesity and co-morbidities. Giving an epidemiological inference to the occurrence of obesity and other cardiac conditions, the journal is important in relaying information of the global significance of obesity situations. This is crucial for the health care teams and other health care policy developers to prepare measures to control obesity. Giving both pharmacological and non-pharmacological interventions in the management of obesity, the journal is in line with the world health intervention policies on management of conditions for achievement of universal coverage of health. The journal is thus one I could consider submitting for my paper as it gives a conclusive coverage of systematic approaches in the management of obesity. It is thus agreeable obesity is a complex and multifaceted disease that is chronic and relapsing; thus, the authors of the journal identify the challenges it can pose to the clinicians making obesity a major health concern (Haidar & Cosman,
