An Online Degree Allows Students to Travel Essay Example

An Online Degree Allows Students to Travel Essay Example An Online Degree Allows Students to Travel Essay An Online Degree Allows Students to Travel Essay There always seems to be two groups of kids who leave high school – those who go on to college and those who take time off to travel. What those kids who travel understand is that there is precious little time to go off and explore the world with no responsibility other than to themselves. But those who do not want to delay their education for travel can now do both with the earning of an online degree. With the explosive growth of the Internet there has been an influx of services available online including educational possibilities for those who wish to pursue their degree without going the traditional route. Online degree programs allow access to a variety of courses through the computer offered by accredited and reputable colleges and universities. Students are able to logon to a secure location where they can complete their reading and other assignments – at their own convenience. Just as important, earning an online degree can be done from anywhere with a laptop. The student can be in the same town as the college or they can be in a different country. The flexibility offered by an online degree program is what really sets this modern program apart.

Executive Summary This report examines the means of communication at universities. A brief definition of communication will be given initially, followed by a description of the means of communication currently used in universities. The report then focuses on e-learning, examining the method and the blended distance course. Within the distance course will examine the synchronous and asynchronous method. So those will be presented this vantage and disadvantage of e-learning compared to the traditional teaching method, being concluded that the e-learning is essential to the educational system and recommended the implementation of distance education at University of Westminster 2. Introduction The communications media used in the educational system has been suffering major changes in recent times. The traditional method has been complemented or even replaced many times by the current method where e-learning has been outstanding. E-learning can bring great benefits to the educational system, complementing or being another option for those who do not have the opportunity to attend the traditional method. The aim of this report is to examine the communication system used on the educational system is special on higher education, focusing on the e-learning method. Firstly, it will talk about the means of communication, secondly the traditional teaching method, third on the e-learning and finally will present the advantages and disadvantages of e-learning compared to traditional teaching methods.   3. Communication The definition of Communication is given by Collins English Dictionary (2009) as the exchange of information, ideas or feeling.† Communication can be classified and divided in different ways. According to Gallegher (2010), communication can be one-way or two way communication; verbal and non verbal, and also says that the communication can be inter or intra communication. 3.1. One way communication and two way communication. One way communication occurs when there is no feedback or interaction during the communication. Two way communication occurs when the recipient asks clarification and interacts with the sender 3.2. Verbal and non verbal The verbal communication occurs when there is the use of words and can be written or spoken. Examples of written communication are: newspapers, posters, advertisements, books, while some examples of spoken communication are: speeches, discussions, lectures and presentations. Non-verbal communication uses other means that is not through writing or speaking, such as facial expression and body language. 4. The means of communication in the educational system The means of communication used in the educational system has been through major transformations following the technological advancement. According to An evaluation of students, the traditional method of teaching in the UK and in most of the world is characterized by one-way transmission from the lecture to the student, which refers to the teacher-center model of teaching, where information is transmitted to the students through the knowledge of the teacher, without much questioning by the student. However, this method has been changed, and the aim of the educational system has been supporting the activities of students rather than simply convey information.   According to Gibbs (1995:1) student-centered method, encourages â€Å"learner activity rather than passivity; students experience on the course, outside the institution-and prior to the course, process and competence, rather than the content where key decisions about learning are made by the student through negotiation with the teacher . The growth of this new method of teaching has as a major factor, the implementation of e-learning by higher education institutions. 5. E-learning According to Clarke (2004), E-learning is a general term that covers different methods which have in common the use of Information and Technology of communication, and may be as a complement to a traditional course as well as an online course where teachers and students do not meet. The term e-learning is the result of a combination occurring between the educations with the help of technology. The e-learning added new meaning to apprenticeship and blew up the possibilities in disseminating of knowledge and information to students and, at a fast pace, opened up new horizons for the distribution and sharing of knowledge, making it also a form of democratization of knowledge for the layers of the population with access to new technologies, giving them the knowledge available, anytime and anywhere. With the development of web technology, the processes of interaction in real time became a reality, allowing to the student to have contact with knowledge, with the teacher and other students, through the media technological 5.1. Blended-Learning This is a new method that has been growing in popularity, which is based on e-learning as a complement to studies in the classroom. Clarke (2004:120), defines blended learning as the integration of e-learning approaches with more traditional methods†. As an example of this method we can mention the Blackboard used by universities. 5.2. Distance courses The training and continual updating of knowledge and skills of human resources are now a crucial element to achieve an effective and efficient performance. The application of information technology and communication to the area of training led to the creation of a new mode of apprenticeship: the distance course. According to Mealy and Loller (2000), Distance Education (DE) occurs when education is provided without the student and the institution being on the same physical location.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   With the distance course the student starts to having time to learn at their own pace, with the assistance of a tutor, without losing the ability to interact with other course participants. 5.2.1 E-learning synchronous and asynchronous 5.2.1.1Synchronous There are two distinct ways of teaching through distance learning: Synchronous and Asynchronous. Synchronous is when teacher / tutor and student / trainees are in lesson to the same time. Can be cited as an example of resources synchronous phone, chat, video conferencing and web conferencing. Through web conferencing, the teacher ministers the classes and students can hear the contents transmitted by the teacher. Thus, students may also ask questions and discussions. This is the model that most closely resembles the traditional teaching. The concept of classroom is extended to distance learning through the use of technology.† Mealy   and Loller (2000:20) 5.2.1.2. Asynchronous In asynchronous e-learning, teacher and students are not in class to the same time. According to Mealy and Loller (2000), the main feature of this method is that the student can participate in the study schedule that suits you. The teacher also is not limited to a specific schedule and can answer questions or participate in discussions at different times of the student. The big difference in asynchronous e-learning is that time is elastic giving greater flexibility to the students in their learning, research and study. 5.3. Advantages and disadvantages of e-learning compared to traditional methods 5.3.1. Advantages According to Remenyi (2005), the three main benefits of e-learning are: Reducing the impact on the environment, quality education affordable and Convenience and flexibility for the student 5.3.1.1. Reducing the Impact on Environment There is no need of traveling; resulting in diminution of pollution reduces the use of papers thereby contributing to the environment 5.3.1.2. Quality education affordable Through e-learning, great teachers can share their knowledge without physical barriers, political, or economic, thus reducing the cost of education making it more affordable, The student can study at a respected university, out of state or even country, e-learning takes the social and physical barriers by giving everyone the same level 5.3.1.3. Convenience and flexibility for the student The materials are more accessible, depending on the method, can be available 24 hours 7 days a week, with no need for change in lifestyle. The student has the opportunity to create a personalized pace. 5.3.2. Disadvantages According Remenyi (2005), the three major disadvantages related to the E-learning is the lack of interaction between student and teacher, the lack of interaction between students and the need for basic computer skills. 5.3.2.1. Lack of interaction between student and teacher The tutor has a higher difficulty in judging the level of acceptance, understanding and retention, since it is not possible an immediate response from the student. There is a need for a higher level of motivation and higher autonomy of learning than classroom training 5.3.2.2. Lack of interaction between students Depending on the method used e-learning, such as the course distance, because there is no participation in the classroom, there is no socialization among students, which can lead to negative outcomes such as lack of ability to work as a team. 5.3.2.3. Need for basic computer skills Need some experience in using computers and Internet usage, also some appetite for the use of technology 6. Conclusion With the increasingly widespread use of new information technologies and communication, it becomes essential the adoption of these in the teaching and apprenticeship. The process that performs this learning environment is called e-learning. In eLearning, flees to the traditional model of teaching, the learning process is student centered, which can build its self-education course, interacting with the available content according to their learning needs in a way flexible, how, when and wherever you want, being the teacher / trainer the catalyst developing this process. In eLearning, the papers the teacher / trainer and school / university are not being replaced. What changes is its function, no longer educational agents, to be partners in apprenticeship. Therefore personal contact is not unappreciated, but become more interesting.

Social disorganization Essay Example | Topics and Well Written Essays - 1000 words

Social disorganization - Essay Example Social disorganization contributes substantially to organized crime by working hand in hand with the aspect of the failure of certain social institutions that lead to the increase of crimes in general. Such include urban decay, general deterioration of the ecology found in inner cities and general failure of the society, as well as familial deterioration. In this regard, crime is affiliated with the level in which one is in the society that he or she lives. This is in relation to social stratification, which stands for divisions of humans in any society based on financial, ethnic, racial or charismatic background. As a result, organized crime is the outcome of blatant flouting of social rules by ignorant members of the society, as well as familial deterioration. This is due to the capabilities that crime gangs have in relation to replacing familial figures and creating a sense of belonging by being part of a crime gang with national syndication. In this light, organized crime is prom oted by the loss of social organization or failure of vital social structures such as family, making crime part f daily life for affected individuals thus; attempting to weed out the evil element in them an uphill task. In addition, failure of other organizations such as law enforcement, crucial for social wellbeing results in organized crime. This is concerning to demand goods and services that are contrary to social norms, beliefs and values, as well as flouting legislation. In addition, social disorganization creates thriving grounds for organized crime in the political front. This is in relation to the influence that organized crime holds on political spheres, and is thus, used to drive campaigns of a political nature in order to maintain power and control. This implies that politicians utilize social disorganization to remain in political power. Social disorganization interacts with the legal world to run crime syndicates, where this is done by conspiring to trade in goods and services that are illegal. Organized crime and social disorganization also interact in the most of unlikely ways concerning white-collar crimes and participation. In this case, those that participate in white-collar crimes such as computer fraud and insider trading participate in such activities following the specialized skills they have and lack of proper channel to exercise them (Matsueda, 2006). This shows failure of the social moral system meaning that leads to development of individuals with flexible morals, ethics, or the total lack of the two. This is due to broken family structures, social justice systems, and political corruption. In addition, white-collar organized crime falls under social disorganization in which case, individual criminality falls within interaction with social groups. This means that the crime rate of a group is determined by the level of organization either for or against crime. In this case, it refers to the goals and ambitions of a given group in crim e, as well as their motivation towards engaging in crime (Matsueda, 2006). Organized crime can be engaged in as a form of gaining recognition from peers by impressing them, although it is for a bigger goal than individual pleasure. Politically, breakdown of structures to the benefit of politicians in generating machinery that works in

Nationalisation of Oil Industry Essay Example | Topics and Well Written Essays - 1500 words

Nationalisation of Oil Industry - Essay Example However, Argentina has been forced recently to reverse its earlier decision to privatize the company by nationalizing 51% of YPF (Minder 2012). This move has been met with a lot of fury from Spain and other major stakeholders who are strongly opposed to move if media reports are anything to go by. The nationalization has been termed a forced purchase. As a result, the Argentine government is required to pay for Rapsol shares. Tracy (2012) reported that the Argentine government made such a move because of Rapsol’s continued failure to invest in gas and oil production in the country, a scenario that has forced Argentina to over-rely on imports to keep up with its high internal demand. For instance, Tracy (2012) reveals that Argentina spent over $9.4 billion in 2011 to import energy from other countries. This was despite the fact that Argentina is considered one of the countries with the largest hydrocarbon reserves in the world. The privatization of YPF snatched away the control of the government over oil and gas usage in the country. It is important for the Argentine government to understand that nationalization of oil supplies in the country has both its advantages and disadvantages. Advantages of Nationalisation to Argentine Government Oil and gas are commodities that contribute massively to the development of the economy of Argentina. As such they are products that should never be in shortage especially now that they are on high demand almost throughout the year. The Argentine government needs to ensure that no shortage of gas and oil is experienced in the country for their economic importance and therefore needs to be in control of the supply of the commodities. One of the main advantages of the move by the Argentine government to nationalize YPF is that it will give the government power to control how gas and oil is utilized in the country. Privatization takes these powers away from the government as has been the case since the Argentine government p rivatized YPF by selling it to the Spanish company, Rapsol. As Tracy (2012) states, the privatization of this YPF gave Rapsol absolute control of how gas and oil are used in Argentina. However, since Rapsol has not been able to adequately invest in equipment to boost productivity as was expected, Argentina has had to depend on energy imports from other countries, this despite its massive potential to produce its own energy. Nationalizing the company will give the argentine government control over the country’s oil and gas resources thereby enabling the government to invest in the petroleum industry and hence reducing its dependency on oil imports. Secondly, nationalization of the company will be of great advantage to the Argentine government in the sense that it will enable the Argentine government to be able to invest heavily in its oil and gas reserves so as to increase the production of oil and gas in the country. Doing this will enable the country become energy sufficient and avoid or reduce its import of energy as noted by Porter (2001). This is based on the fact Argentina is one of the countries that experiencing high-energy demand in the country. However, just as Tracy (2012) pointed out, privatisation of YPF interferes with the sector that used to supply much of Argentina’s gas and oil. As earlier indicated, Argentina spent over $9.4 billion dollars in 2011 alone because of energy shortage in the country. However, a closer look at what caused this shortage points at the inefficiency of

Evolution of Substrate Integrated Waveguide (SIW)

Evolution of Substrate Integrated Waveguide (SIW)  ­Ã‚ ­EVOLUTION OF SUBSTRATE INTEGRATED WAVEGUIDE STRUCTURES: AN OVERVIEW , and Abstract — Substrate integrated waveguide(SIW) is the most captivating technology for easy integration onto planar substrates for millimeter wave components and systems for the next decade. This guide is synthesized on the substrate with arrays of metallic posts retaining the low loss advantage of conventional rectangular waveguides. In this paper, various evolving structures of SIW which had been implemented for various practical applications like filters, couplers, antennas etc are reviewed and some ongoing projects based on this technology are also presented. Index Terms —  Filters, couplers, substrate integrated waveguide (SIW) INTRODUCTION Metallic waveguides are preferred over traditional transmission lines like coaxial cables wherein high losses are accounted, namely, copper losses and dielectric losses [1]. Metallic waveguides inherit the advantage of high power handling capability and high Q-factor [2]. In spite of its aforementioned advantages, it is not yet a very promising technology because of its bulky and non planar nature [3]. Slot like planar printed transmission lines are next to metallic waveguides used in microwave integrated circuits (MICs). These were planar in nature but not suitable at smaller frequencies due to its transmission losses [4].      To bridge the gap, SIW is introduced, a very promising waveguide structure which maintains the advantages of a rectangular waveguide, such as high Q-factor and high power handling capability in planar form [5-7]. Basically in SIW, two parallel metallic layers of substrate are connected via metallic posts introducing structure similar to common metallic waveguides. Generically, the substrate integrated waveguides (SIW) are known as substrate integrated circuits (SICs) [8]. SIW is the most popular topology among others family members of SICs because the design techniques of rectangular waveguide can be applied directly to this topology. The SIW technology has been implemented with millimeter and microwave components as it is suitable for high frequency range because of its accounted leakage losses at low frequency. They can be directly connected to planar circuits, namely, micro strip line and coplanar waveguides (CPW), allowing for easy integration of active circuits thus making it su itable for mass production . In this paper, evolutions of SIW structures are studied and different application of SIW technology are presented, and some ongoing projects are discussed later. EVOLUTION OF SIW STRUCTURE At millimeter wave frequency, electromagnetic coupling between building blocks of antenna makes designing a very critical issue. To provide great deal of flexibility for designing of components, concept of SICs is introduced. SIW, which are synthesized on planar substrate in which metallic posts are perforated in the embedded substrate using printed circuit board technology shown in fig.1. [9] Fig.1. Substrate Integrated Waveguide The steady and constant rise of wireless user has fuelled an increase in wireless applications. For the fulfillment of increasing day to day needs of communication, various evolving structures of SIW are proposed. Substrate integrated slab waveguide (SISW), a new variant in the SIW toolkit is hereby introduced [10]. The structure offers an increase in bandwidth by adding air holes into an SIW mainly for wideband microwave applications. Compared to rectangular waveguides, a size reduction of is achieved with SIW. Unfortunately, SIW are still large (compared to their micro strip counterparts) for various practical applications and hence substrate integrated folded waveguide (SIFW) is proposed [11]. In SIFW size reduction of (9) is achieved by using dual layer substrate but its losses are increased. Also there are half mode substrate integrated waveguides (HMSIW) [12] which increases the bandwidth and can also have a reduced size while maintaining the advantages of SIW. Recently after HMSIW, folded half wave substrate integrated waveguide (FHMSIW) is proposed but there are complexity issues which needs to be solved [13].For effective utilization of waveguide channel, hybrid SIW is proposed in which waveguide channel usage is maximized by routing a strip line inside the substrate [14]. Novel class of bandwidth enhancing structures are proposed, namely ridged substrate integrated waveguide (RSIW) [15] shown in Fig.3 and ridged substrate integrated slab waveguide (RSISW) [16].In former structure, side walls of top and bottom metal layers are connected by full height metallic posts and central row of partial heighted metallic posts are connected at their bottom by a metal strip. The latter structure is having the similar geometry of RSIW but additional air holes are included to further increase the bandwidth. Also there are unpopular structures like honeycomb substrate integrated waveguide (HCSIW) and folded corrugated substrate integrated waveguide (FCSIW). HCSIW cr eates partially low dielectric region by drilling air filled posts vertically [17] and FCSIW is used for back lobe suppression [18]. For two different modes of propagation, switchable substrate integrated waveguide (SSIW) (via the biasing of pin diode switch) is introduced [19]. Another variant of HMSIW is rotated HMSIW, to improve the manufacturing tolerances by enabling direct interaction with wave energy at central point which is not feasible for the structures discussed earlier[20]. Recently, Butterfly substrate integrated waveguide; another variant has been added to the SIW toolkit for better gain and low side lobe levels. [21]. Latest variant added to the SIW toolkit is empty SIW (ESIW). This structure eliminates the disadvantages of dielectric substrate by replacing it by novel empty substrate (air filled) while maintaining the advantage of complete integration in planar substrate [22]. Outlines of important configurations of SIW are shown in fig.2. [11], fig.3.[15] and fig.4 [21]. Fig.2. SIW Main Variants Fig.3.RSIW Structure Fig.4.Butterfly substrate integrated waveguide FUTURE TRENDS IN SIW SIW, a very promising technology has been implemented for many practical applications like SIW based shifters, oscillators, resonators, filters, power dividers, diplexers, mixer, antennas and many more [23-30]. Currently there were many ongoing projects in progress based on SIW technology. A very few have been mentioned here in this paper. Efficient synthesis and design of reconfigurable micro electro mechanical systems (MEMS) based band pass filter (BPF) in SIW technology [31] is one of the ongoing projects. This project is focused on the development of novel microwave and millimeter wave fully reconfigurable BPF on SIW so that advantages of miniaturization, easy integration onto planar substrates, low losses, high power handling can be achieved. This project tries to combine the advantages of novel comb line SIW resonators with the enhanced characteristics of MEMS varactors to tune the response of coupled resonator filters. These filters are key components of emerging RF front ends for future telecommunication systems. SOSRAD-77GHz SIW system on substrates (SOS) radar front end is the other ongoing project based on SIW [32]. The aim of the project is to establish SIW technology as the leading high performance platform to encompass all available technologies within a common substrate at mm-wave frequencies. Some of the completed projects on SIW technology are stated; integrated focusing systems in SIW technology: full wave modeling and optimization [33] and Design and development of SIW based RF circuits and components using metamaterials in ku-band application [34].

Crisis of Conscience Essays -- Literary Analysis, Joseph Heller

In Catch-22, Joseph Heller creates a surreal world of irrationality to illuminate madness and corruption. Through the satirical characterizations of the novel's leaders, Heller criticizes not just the institution of war but all forms of bureaucratic establishment. The authority figures in the novel are portrayed as selfish and deranged maniacs without any sense of morality, driven purely by their desires to expand their power and reputations. These leaders are able to skew reason to their benefits through their followers’ acceptance of conformity and conventions. The novel's protagonist, Yossarian, however, rejects the pressures of conformity and is unwilling to accept his leaders' illogical projections of truth and duty. By running away to rescue Nately's whore's sister, Yossarian is able to overcome the oppression of authority and find his own sense of purpose by deciding for himself what is right and pursuing it. This victory advances Heller’s commendation of standi ng up against the conventions of society and refusing to accept truth blindly. Joseph Heller’s novel makes use of humorous surrealism to illuminate corruption in society. Heller admits that in his novels, â€Å"the texture, the approach,† as opposed to the â€Å"basic story line, the sequence of action,† is what â€Å"makes them distinctive† (Rielly). Indeed, at its most basic level, the plot of Catch-22 is hardly surrealistic or unconventional at all; it is a reasonably historically accurate portrait of the end of the Second World War. The missions Yossarian flies, the deaths he witnesses, and the poverty he observes are all true to the setting. Many events in the book, such as the mission where Yossarian and his comrades are ordered to bomb a civilian city to create a roadbloc... ...on to be part of an "American traditions" of literary rebels who "escap[e]... in order to save [themselves] from absurdity, compromise, or dispair" (McDonald). Though Heller intended the moral ambiguity of escaping military service "to raise a question rather than answer one," Yossarian's final action ultimately represents a triumph of nonconformity (Rielly). He is able to see the fraudulence of the war and decides that a 'disobedient' life helping a lost girl is more worthy than a 'dutiful' one serving a corrupt general. Through this decision, Yossarian is able to find purpose and moral satisfaction in his own life. This personal victory celebrates the power of nonconformity. In boldly rejecting societal expectations to pursue the life one believes in, goodness can be pursued, evil can be challenged, and the truth strength and value of an individual can be found.
