Guns, Germs and Steel essays

Guns, Germs and Steel essays As Jared Diamond, a biologist, was doing research on tropical birds in New Guinea, he spoke with a local politician named Yali. The spoke about the origins of their peoples and about the commodities that Europeans brought to New Guinea such as steel, clothing, various food, etc...Yali then posed the question of why Europeans had so much to bring and that the people of New Guinea and people like them did not. Yalis question goes to the heart of the question to the modern world; why are there such inequalities in the modern world regarding wealth and how did it evolve. In attempting to answer this question, Diamond touches on several factors that are woven into the answer such as food production, domesticated plants and animals, metallurgy, weapons, communication, and better political organization. These factors are crucial element in the development of the world we presently live in. An example of how different societies had an obvious advantage over each other is exemplified in the encounter between Francisco Pizarro and the Inca emperor, Atahuallpa. This meeting illustrates the basic advantages which the Europeans enjoyed over much of the world at this time. Pizarros victory over the Incas is an perfect representation of how the culmination of many centuries of developments had given Europeans an obvious advantage. Diamond's basic hypothesis is that the Europeans were not "superior in any innate sense over the Incas or Aztecs, but more blessed by geography and nature. The advantages enabled whites to conquer non-whites easily; not only by means of technological advances or the use of large animals as weapons but also the influx of diseases that are developed in concentrated and sedentary societies. After the emergence of humans from our species from African apes, humans spread from Africa throughout the world. The societies that were prevalent at that time were that of hunter-gatherers. Around that ti...

Land Rover and its Business System Case Study Example | Topics and Well Written Essays - 3000 words - 1

Land Rover and its Business System - Case Study Example Now finally the Land Rover is working under the hands of Tata Motors from 2008. (Land Rover confirms grant offer to build a new model, March 2009) (Land Rover Company Profile, April 2009). At present, the company is all set to start its revolutionary project of making the smallest, lightest and most fuel-efficient car that Land Rover has ever built, based on the LRX concept vehicle displayed in the auto show at Detroit last year. The project has got the grand welcome by the UK government by a stimulus package of  £27 million in the month of April, as a support to the UK auto industry whose sales has gone down by 30% in the second half of 2008 and as per the analysis report the situation yet takes some more time to get back to the same level. Phil Popham, the managing director of Land Rover, said: "At the moment we are planning on the assumption that it will be a couple of years before the industry starts to improve drastically, and maybe five years before returning to the pre-credit crunch trends we were seeing globally in the motor industry." (Arnott S., April 2009). The project is going to cost around  £400 million and is to be started by the year-end in Halewood, on Merseyside. The project is primarily taken up due to the shift of the global auto industry towards green cars to check the global warming and also is a part of raising efforts towards making more fuel efficient and cost effective cars. The prevailing economic recession which has made consumers more cautious about their spending and other related factors have driven the demand for lighter, relatively low priced, fuel efficient and environmentally friendly cars. Under European law, automakers have to cut carbon emission of new vehicles by 19% within a period of five years (Arnott S., April 2009). But, Jaguar-Land Rover under sustainability programme is expecting to cut the same by 25%.  The parent company of Land Rover has already taken the initiative to make the world’s lowest cost car â€Å"Nano† (Scanlon J., March 2009).

Study of protocols in a VoIP network Essay Example | Topics and Well Written Essays - 4000 words

Study of protocols in a VoIP network - Essay Example These applications later came out with voice conversation features in which users utilize computer headsets or IP telephone handsets in communicating with one another. Services like call forwarding, conference calling, voicemail, contact management and directory assistance were later added and paved the way for the creation of a new revolutionary technology - Voice over Internet Protocol or VoIP. This development has captured the attention of telecom regulators and operators who have now started to embrace the technology as one of their mainstream services. The two most popular protocols, H.323 and SIP will be discussed in this report. H.323 is a standard for the transmission of real-time audio, video, and data information over IP-based networks. The standard contains specifications on the components, protocols, and procedures required in providing multimedia communication over local-area networks (LANs), metropolitan-area networks (MANs), wide-area networks (WANs) and even enterprise networks (ENs). Applications of H.323 may include IP telephony (audio only), videotelephony (audio and video), audio+ data and audio+video+data. H.323 can also be used for point-to-point or point-to-multipoint-multimedia communications like videoconferencing. Based on these applications, it can be seen that the standard can be utilized in a wide market segment - from consumer to enterprise to telco services. The H.3 Versions The H.323 standard is specified by the ITU-T Study Group 16. Version 1 was formulated in 1996 and refers to visual telephone systems and equipment for LANs that provide a nonguaranteed quality of service (QoS). It is geared more for consumer applications via LANs and the Internet. Version 2 of the standard was formulated in 1998 to accommodate the introduction of new voice-over-IP (VoIP) applications and IP telephony. The absence of a governing standard for these applications resulted to incompatibility of PC-based equipment and PBX or PSTN-based peripherals, so the new H.323 version was defined. At present, there are moves to add new specifications to the standard for new applications like fax-over-IP networks, gatekeeper-to-gatekeeper communications, and fast-connection mechanisms. This will pave the way for Version 3 of the standard. Components The H.323 standard specifies four kinds of components: 1. Terminals. An H.323 terminal can either be a personal computer (PC) or a stand-alone device, running the multimedia applications. It primarily supports audio communications but can optionally support video or data communications. The primary goal of H.323 is to interface standard-defined equipment with other multimedia terminals. 2. Gateways. A gateway refers to the equipment used to provide connectivity between an H.323 network and a non-H.323 network. The H.323 network can consist of PCs and PC-based peripherals while a non-H.323 network can refer to a PBX or PSTN network. In order to achieve connectivity between these two dissimilar networks, translating protocols were developed for traditional telephony features like call setup and release. It should be noted that a gateway is not required for communication between two H.323 terminals within an H.323 network. 3. Gatekeepers. A gatekeeper is necessary if an H.323 network will be implemented with services such as billing, addressing, call-routing, bandwidth management and authorization and

Explain the importance of Curleys Wife in the novel Essay Example for Free

Explain the importance of Curleys Wife in the novel Essay Plan: * Symbols red lipstick * Not given a name Curleys wife may seem an insignificant character because she has not even been given a name by Steinbeck. Her name suggests that she is nothing more than one of Curleys possessions. When she first appears in the novel, she is dressed up as if she is planning on going out into town, rather than just spending her day wandering around the ranch. The image of her being a sex object is emphasised by the fact that Curley keeps a glove fulla Vaseline, for her benefit. However, Curleys wife is influential to the book as she characterises loneliness, the longing for the American dream, danger and sexism. Her appearances in the novel are extremely important at they change the entire mood of the scene in which she appears in. We see that the first time we are introduced to Curleys wife, she is heavily made up; full, rouged lips, red fingernails and red mules. The colour red symbolises danger and sexiness, and the fact that she is wearing these items creates a sense of foreboding that she will be the cause of George and Lennies failure to achieve their dream of having their own plot of land. Another symbol is shown by the rectangle of sunshine in the doorway was cut off. This immediately creates a sense of danger and doom in the readers mind due to the absence of light. However, we can see that the reason for Curleys wife being flirtatious is because she wants to get away from the loneliness that surrounds her. By flirting, it means she can communicate with other men who otherwise would not talk to her because they do not want any trouble with Curley. However, by being flirtatious, she actually increases the hostility of the other men on the ranch as they become suspicious. We can see that she tells Lennie; I get lonelyAint I got the right to talk to nobody? However, she then explains the reason behind her flirtatious nature; I cant talk to nobody but Curley. Else he gets mad. However, we actually see that the marriage between them is already starting to break down because Curley thinks that his wife is givin Slim the eye. Curleys wife is also important as she conveys the theme of sexism. We see that Curley, who keeps his hand soft for her, regards her as a sexual object. Instead of showing any consideration towards his wife, Curley only wants to increase his sexual prowess. The only way in which Curleys wife can talk to other men is by; dolling up. However, when she does this, they talk even less to her, driving her behaviour further. Therefore, she remains excluded from everyone. We even see that Whit regards Susy higher than Curleys wife; a laugh and hell of a nice place. This is a rare time when any woman in the novel is actually shown any kindness, and a complement. Curelys wife, as with many of the other characters, wants to live out the American dream; Coulda been in the movies. It is this dream that drives and compels her to carry on with her otherwise miserable life on the ranch. However, her sudden death shatters her only hope of being able to get away from ranch life, where she is clearly not happy. We can see that the shattering of her dream is mirrored exactly by the death of Lennie, ending the dream for George and Candy. This shows that because she failed living the American dream, it is an ominous foreboding of the fate for George and Lennie. Curleys wife also plays an essential part in the novel, as she plays crucial parts in changing the mood of the scene. When she is first introduced, hope created by the arrival of Candy is wiped out and the reader gets an ominous warning, which is emphasised by Georges caution to Lennie; you keep away from herjail bait. Furthermore, when Curleys wife arrives in chapter four, the excited mood created by wanting to achieve the American dream, changes to a more melancholy mood. We can see that because Curleys wife is lonely all the time, she has turned into a spiteful and vicious person; a nigger and a dum dum an a lousy ol sheep.

The Role of the Media in Rwandas Violence Essay -- History Media Viol

Many situations and acts that are unacceptable need a stressor. Stressors are situations and/or events that lead to a catastrophic outcome, such as the Rwanda genocide. The tension between both the Hutu and Tutsi already existed; it only needed something to reach its breaking point – a stressor. On April 6, 1994, the plane that occupied Juvenal Habyarimana, President of Rwanda, and Cyprien Ntaryamina, President of Burundi crashed due to unexplained circumstances. Over the next three months in Rwanda after the crash carrying both Presidents, mass killings began to occur. The kill count escaladed dramatically leaving one million Rwandans dead and two million seeking refugee status among its neighbors: Zaire, Tanzania, and Burundi (Kellow and Steeves 1998). This stressor is a key contribution to the events that followed; the Rwandan Genocide. â€Å"The rise in tension and violence, the wide distribution of arms to civilians and militia, and the increasingly vehement anit-Tutsi p ropaganda broadcast by Radio Libre de Mille Collines, all indicated the growing potency of ethnic hatred† (Uvin 1998, 83-84). Ethnic hatred centered on the hostility and segregation towards a particular group, in this case the Tutsi. The use of fear, rumor, and panic enabled the unsteady decline of trust between the Hutu and the Tutsi, which eventually escaladed to pure ethnic hatred (Kellow and Steeves, 1998; Straus, 2007; Uvin, 1998). The role of the media in the Rwandan genocide contributed to further violence and hatred among the Hutu and the Tutsi residents. One of the ways in which information could be obtained throughout Rwanda that was easily accessible was through public broadcasting particularly the radio. Through radio broadcasting it enables the public... ... Rwanda before RTLM took over its frequency during the early stages of the genocide (Thompson 2007, 390).

Section 2. Getting started Overview of Rational Performance TesterIBM Rational Performance Tester, hereafter known as Performance Tester, is a performance test creation, execution, and analysis tool that helps development teams validate the scalability and reliability of their Web-based applications before deployment. Many of Performance Tester's features have been explicitly designed with the novice load tester in mind. Performance Tester allows you to use one of several Web browsers (Internet Explorer, Mozilla, or Firefox) to test a Web-based application. The results of your interaction are captured and recorded on the operating system of your choice (Windows or Linux).The test is presented in a concise tree-based editor that is capable of exposing underlying details to the expert on an â€Å"as needed† basis. Test scripts are then grouped together in various combinations to reflect the multiple types of user that comprise the projected user population. You can specify the number of simulated system users at execution time. Test execution is accompanied by easy-to-read, real-time reports that update throughout the test run. Bottlenecks based on metrics such as round-trip performance, transaction rates, and system diagnostics are highlighted in these reports.You can also use Performance Tester to further identify the root cause of poor performance problems from the hardware- or software-component level through advanced resource monitoring and response-time tracking. Although this tutorial focuses on testing a J2EE, Web-based application, you can use Performance Tester to test any Web-based application. You can also extend Performance Tester to test the performance of additional application types such as Siebel, SAP, and Citrix (see Resources). Setting up the tutorial environment Rational Performance Tester  © Copyright IBM Corporation 1994, 2008.All rights reserved. Page 3 of 26 develop erWorks ® ibm. com/developerWorks As previously mentioned, the easiest way to access this tutorial is through the online trial system developed using the Citrix Access Platform. The trial system gives you free access to Performance Tester, WebSphere Application Server 6. 0, and the Adventure Builder sample application, and minimizes your installation and configuration time for the tutorial. Once you have registered for the online trial system, installed the Citrix Metaframe Presentation Server, and logged into the server, you are ready to begin.Performance Tester will launch in a Citrix client session and will appear just as if it were running on your local desktop. You can interact with it just as you would if it were installed locally. The countdown clock on the Rational Test Drive Environment Web page will keep track of the time remaining in your session. If you choose to set up the tutorial environment locally you will need to install and configure Rational Performance Tester and WebSphere Application Server 6. 0 in your workstation. Note that the Adventure Builder sample application used by this tutorial is only available with WebSphere Application Server 6. , not 6. 1. You should also allow additional time to create and configure a project in which to store your test artifacts before starting. The tutorial is written from the assumption that you are using the online trial system. Performance Tester and Eclipse Performance Tester is based on the open-source Eclipse platform. Eclipse provides a rich working environment for many tools, both open source and commercial, including many of the offerings of the Rational Software Delivery Platform such as Rational Software Architect, Rational Application Developer for WebSphere Software, and Rational Functional Tester (see Resources).This provides a common user experience for tooling across the software development life cycle. Not only are these tools all based on Eclipse, but often times they actually share th e same shell. In other words, the capability of each of these tools is presented to the user as a new perspective in the same shell. A perspective is a consolidation of tools and views focused on one particular task. The perspective for Performance Tester is known as the Test perspective. As the name implies, the Test perspective provides views that are needed by a developer or QA professional focused on testing a software application or system.The tutorial workspace and sample projects Assuming you are using the online trial system, Performance Tester will be associated to a pre-configured workspace. A workspace can be any directory location where your work is stored. In your case, this workspace contains two projects. The first project is the Adventure Builder Application. This project contains the source code for the Adventure Builder sample application you will be testing. The application has already been deployed to WebSphere Application Server on the online trial system. The p roject is only in your workspace so that Rational Performance Tester Page 4 of 26 Copyright IBM Corporation 1994, 2008. All rights reserved. ibm. com/developerWorks developerWorks ® Performance Tester can navigate to the source code later when you are attempting to find the root cause of a performance bottleneck. The second project, Adventure Builder Performance Tests, is the test project you will use to store your tests, datapools, schedules, and results. If you expand the project, you will see several folders used to organize your test assets. You can add, remove, and customize folders as you like. There isn't much to examine in this project yet. You will look more closely at it once you have recorded a test.Figure 1. A Performance Tester workspace viewed in the Test Navigator Section 3. Record a test scenario Performance tests are most often created by recording your manual interactions with the system under test. In this section of the tutorial, you will use the automated HTTP recorder to capture the scenario of interacting with the Adventure Builder sample application to construct a vacation package and purchase it. The Adventure Builder application is already running in the online trial environment. All you need to do is connect to it through a Web browser while the recorder is engaged.Browser support Although you are using Internet Explorer in this tutorial, Performance Tester can work with any Web browser that supports SOCKS proxies. Performance Tester can automatically launch Internet Explorer, Mozilla, and Firefox. Rational Performance Tester  © Copyright IBM Corporation 1994, 2008. All rights reserved.

This will cause Performance Tester to begin generating the test based on the traffic it has captured. Section 4. Review and customize the test Performance Tester generates a test based on the HTTP traffic it captured during the recording. The test is much more than a simple HTTP trace log, however. Behind the scenes, Performance Tester does a lot of processing to create a test that is robust, extensible, and easy to maintain. In this section, you will examine the generated test in greater detail and customize it to use unique data.Examine the test Animated demo Would you like to see these steps demonstrated for you? me Show The test is represented in a tree format in the left portion of the Test Editor view.

You can edit this data if you need to change the host, URL, request header values, or any other field. Automatic data correlation Animated demo Would you like to see these steps demonstrated for you? me ShowWeb applications tend to be highly dynamic. For example, in the scenario you recorded you placed an order for a vacation package and were given a unique order ID. You then used that order ID to check the status of your purchase. When you play-back this test, it will place another order and you will be given a different order ID. You would want Performance Tester to check the status of that new order ID, not the one you previously recorded. For that reason, Performance Tester performs automatic data correlation. That is, it looks at data parameters sent to the server and matches them up w ith prior response data from the server.Accessing the correlated data is easy.

Modern Web applications have many layers of caching. If you were to emulate a thousand users using the application doing exactly the same thing, you would not observe typical performance behavior.Once the first emulated user performed the transaction, all the subsequent users would be drawing information from the cache. For this reason, performance test engineers often spend much of their time configur ing tests to pull random data from a â€Å"datapool† so that each emulated user uses unique information. Performance Tester automatically identifies likely candidates for datapool access and makes it possible to associate these fields with data sources you provide. 1. Select the Enter Adventure Package Details page node in the test contents. Notice in the Test Data area the start_month, start_year, and start_day parameters.These were the default values in the Options page, which were subsequently transmitted back to the server when the Set Package Options button was clicked.

In this trial environment, the Performance Tester load generation, Web server, application server, and database server are all running on a single machine. You would normally track resources on each tier of your application. In addition, the load test you just ran was of very short duration. Normally, performance tests will be significantly longer, allowing the systems to reach a steady state. Nonetheless, the trial system gives you a sense of how easy it is to track resource utilization during a performance test.If you have a concern, you can now go to the Response vs. Time Detail tab, right-click on the graph, and click Add/Remo ve Performance Counters to overlay resource counters onto page response data.

Public Sphere

â€Å"The idea that a public sphere to which everyone can contribute on equal terms is simply a fantasy. † To believe that there exists a public sphere where every single member contributes on an equal level is highly unrealistic. Correspondingly, many academics have critically supported as well as argued against this view. There will be discussion of the public sphere and various writer’s views and concepts regarding it, with specific references to Howley (2007) and Turnbull (2006), as well as Hackett (2010), Holub (1994), Apppadurai (2000), Meikle (2008), and Fraser (1990). The different academics will introduce and discuss; an ideal and flawed public sphere, a democratic public sphere, and the important roles of audiences and participants. Furthermore, there will be a particular focus on Habermas, his theories and findings consequently deconstructing his ideas on his bourgeois public sphere theory. Overall, the key argument in this discussion is that the public sphere is ideally seen as an arena for equal opinions, however pragmatically this is not the case and it is difficult to achieve it because of the different factors that exist between individuals and participants. Holub (1994) explains the public sphere as; â€Å"a realm in which opinions are exchanged between private persons unconstrained (ideally) by external pressures. Theoretically open to all citizens and founded in the family, it is the place where something approaching public opinion is formed. It should be distinguished both from the state, which represents official power, and from the economic structures of civil society as a whole. Its function is actually to mediate between society and state; it is the arena in which the public organizes itself, formulates public opinion, and expresses its desires vis-a-vis [face to face with] the government†. Similarly, a majority of modern conceptualisations of the public sphere relate back to Jurgen Habermas and his bourgeois public sphere. Habermas defines it as a space of reflective discussion about issues and subjects of a common interest, following an informed democratic procedure (Meikle 2008). Thus, a relevant example would be; supplying different resources of media to developing countries in preparation for an election or some sort political decision. By doing this, individuals are being provided an informed democratic process, allowing them access to sources of independent media to make a more informed decision before they elect. This is often present in events such as elections as it is an arena where private people come together as a public; as one. By looking back, the characteristics of the public sphere have not changed when comparing the old and contemporary. Meikle (2008) discusses how Habermas emphasized the role of periodical press in the development of his public sphere (p. 129), describing it as the ‘coffee-house culture’ and how at the time people would sit and discuss topics and events which would in turn lead to influencing the political culture of the 17th and 18th century. However, it must also be noted that Habermas’ accepted criticism to his notion, as well as making it clear that the public sphere is not given to every type of society, and it does not own a fixed status. Furthermore, Meikle (2008) also likens the public sphere to a place where participants can discuss their ideas freely. However, it is important to regard these definitions as the ‘idyllic’ public sphere, Holub (1994) mentions ‘ideally’ in brackets, because realistically it is unachievable to have this sort of ‘perfect’ public sphere where everyone contributes equally. Many academics have criticized Habermas’ bourgeois public sphere, questioning if it ever really existed, and if it did, would it really be able to ever exist again? On that note, Hackett (2010) brings forth the notions that this concept of Habermas’ public sphere that presumes rationality, equality is false, and consequently, he critiques it, alongside Fraser (1990), saying that; â€Å"it embeds a masculinist notion of rationality, and a taken-for granted gendered distinction between private and public spheres. It ignores the ‘counter’ and minority public spheres of subordinate groups, the intrusion of social and economic inequalities into the processes of the public sphere, and the conversion of public opinion into effective state policy through representative political mechanisms. (2010, p. 4). Additionally, Fraser (1990) looks at how Habermas’ theory of the bourgeois public sphere constitutes a number of exclusions, in particular excluding women and individuals of lower social class, as it was not accessible to all. Lower class people did not have the resources and women did not have the same rights, privileges and power as men, in society, to have their equal say. Moreover some of these factors are still relevant, such as the social classes and accessibility to resources. Furthermore, Fraser (1990) mentions the exclusion of subordinate groups, where she states â€Å"subordinate groups sometimes cannot find the right voice or words to express their thoughts, and when they do, they discover they are not heard [and] are silenced, encouraged to keep their wants inchoate, and heard to say ‘yes’ when what they have said is ‘no. ’† (1990, p. 64). It is evident, that this access, whether it is technological, power or status related, to contributing to the public sphere still does not equate to equality. Rather, the factors that need to be considered are not access alone, but also what kind of ‘voice’ the speaker possesses in society. All of which are dependent on a number of factors, such as the speaker’s status in society, gender, age, class, education, culture and country. Moreover, public spheres are relevant in today’s new social media’s like Twitter, Facebook and various blogs. They create an arena in which social sites, like these, generate meanings which are then distributed and discussed amongst a large audience, consequently becoming a public sphere and letting interaction occur with all its participants. This emergence of social media has called for a new public sphere to be formed. Meikle (2008) discusses how media is an integral aspect of the public sphere and that in present society, it is inescapable. Media plays an obligatory part; today’s â€Å"newspapers and magazines, [internet,] radio and television are the media of the public sphere† (Habermas in Meikle, 2008, p. 128). However, for Habermas this role that media plays is an issue, stating that the world shaped by the mass media is only a public sphere on the exterior; only in ‘appearance’ and nothing else. Though the public sphere cannot be regarded as equal, Meikle does suggest that it can be look at in a positive sense; regarding it as a useful standard against which we can measure how the media actually do operate (Meikle, 2008, p. 131). Furthermore, Habermas’ ideal public sphere has often been said that it is being compromised by contemporary tabloid media and culture. It produces a blur between the private and public spheres in regards to celebrity culture and making their private lives a public concern and discussion. As well as regarding media as just pure entertainment, the tabloid media are constructing participants who only consume what they are being fed by the media instead of making their own informed decisions (Meikle 2008). Furthermore, Habermas (in Meikle 2008) believes that our contemporary political mediascapes, which refers to the â€Å"distribution of electronic capabilities to produce and disseminate information [such as] newspapers, magazines and†¦ Television stations† (Apppadurai, 2000, p. 326), are in fact are a long way away from being an ‘ideal public sphere’. He looks at how â€Å"public opinion is no longer produced by the public, instead, public opinion is now something produced for the public† (2008, p. 129) we are being influenced and there is no opportunity to discuss ideas freely, or for there to be complete equality in the contribution to the public sphere because of the different factors that come into play. Similarly, Habermas (in Meikle 2008) uses the term ‘equals’ in regards to participants in the public sphere. Yet, Meikle (2008), in accordance to Fraser’s (1990) view, discusses how the public sphere cannot guarantee each person’s contribution to be of equal amount. This is because of the reasons and factors that exist in society such as; power and status; celebrity power over ordinary individuals, access to resources; developed and developing countries, and gender; the imbalance of power between men and women. Turnbull (2006) looks at the roles of audiences, and why their role is so vital in instances like these. Turnbull discusses the media’s audience and argues how media is looked at as a centrality in our lives and world, some have less or no access and the social and cultural context of the individual is â€Å"embedded in their access to and use of various media technologies†Ã¢â‚¬ ¦ The â€Å"participation [of audiences] in an increasingly mediated public sphere may be largely conditional† (p. 80), as it alters the stance on every participant having an ‘equal’ contribution to the public sphere. Howley (2007) states that people need to promote a more democratic media culture, for a place that individuals can share their mutual interests and concerns, discuss topics. He supports that there is not one sole public sphere because there is not a single medium that is ‘perfect’ (pp. 357-358). Furthermore, Howley (2007) brings forth the idea that the public sphere is the centrality for media institutions but is also significant for media students, providing a theoretical perspective; it helps to emphasize the essential and crucial relationships between democracy and modern communication systems. As the role of a democracy, a citizen who is informed and wishes to engage, needs to be accommodated by the media; providing them resources of news, information and opinion, for that individual to then be able to use this to identify themselves towards this common interest. However, this notion of a democratically public sphere has issues that arise, the main one being the nature and conduct of public discourse in a highly mobile and heterogeneous society. By regarding societies that have things like ethnic, religious and cultural diversity, partisan politics, and economic stratification present, the sole idea of achieving agreement on matters of public policy seem inaccessible and unachievable. Also, another issue is the â€Å"contemporary media systems – characterised by unprecedented consolidation of ownership and control on the one hand, and the fragmentation of mass audiences into even smaller ‘niche markets’ on the other – makes issues of access to and participation in public discourse equally problematic† (pp. 343-344). Thus, this idea of an equal and democratic public sphere is difficult to have and carry out. In conclusion, the ideal public sphere tries to offer a place where people are able to discuss their ideas freely between one another. However, to believe that individuals can discuss in a completely free manner, with no influence and be complete equals, contributing on equal terms, is a far-fetched hope. There can only ever be a place of equality and rationality in an ideal society, as factors of social, linguistic and cultural inequalities, rights and even freedom of speech of an individual, all affect any possibility of equal communication and contribution between people in a public sphere.

Furthermore, Habermas (in Meikle 2008) believes that our contemporary political mediascapes, which refers to the â€Å"distribution of electronic capabilities to produce and disseminate information [such as] newspapers, magazines and†¦ Television stations† (Apppadurai, 2000, p. 326), are in fact are a long way away from being an ‘ideal public sphere’. He looks at how â€Å"public opinion is no longer produced by the public, instead, public opinion is now something produced for the public† (2008, p. 129) we are being influenced and there is no opportunity to discuss ideas freely, or for there to be complete equality in the contribution to the public sphere because of the different factors that come into play. Similarly, Habermas (in Meikle 2008) uses the term ‘equals’ in regards to participants in the public sphere. Yet, Meikle (2008), in accordance to Fraser’s (1990) view, discusses how the public sphere cannot guarantee each person’s contribution to be of equal amount. This is because of the reasons and factors that exist in society such as; power and status; celebrity power over ordinary individuals, access to resources; developed and developing countries, and gender; the imbalance of power between men and women. Turnbull (2006) looks at the roles of audiences, and why their role is so vital in instances like these. Turnbull discusses the media’s audience and argues how media is looked at as a centrality in our lives and world, some have less or no access and the social and cultural context of the individual is â€Å"embedded in their access to and use of various media technologies†Ã¢â‚¬ ¦ The â€Å"participation [of audiences] in an increasingly mediated public sphere may be largely conditional† (p. 80), as it alters the stance on every participant having an ‘equal’ contribution to the public sphere. Howley (2007) states that people need to promote a more democratic media culture, for a place that individuals can share their mutual interests and concerns, discuss topics. He supports that there is not one sole public sphere because there is not a single medium that is ‘perfect’ (pp. 357-358). Furthermore, Howley (2007) brings forth the idea that the public sphere is the centrality for media institutions but is also significant for media students, providing a theoretical perspective; it helps to emphasize the essential and crucial relationships between democracy and modern communication systems. As the role of a democracy, a citizen who is informed and wishes to engage, needs to be accommodated by the media; providing them resources of news, information and opinion, for that individual to then be able to use this to identify themselves towards this common interest. However, this notion of a democratically public sphere has issues that arise, the main one being the nature and conduct of public discourse in a highly mobile and heterogeneous society. By regarding societies that have things like ethnic, religious and cultural diversity, partisan politics, and economic stratification present, the sole idea of achieving agreement on matters of public policy seem inaccessible and unachievable. Also, another issue is the â€Å"contemporary media systems – characterised by unprecedented consolidation of ownership and control on the one hand, and the fragmentation of mass audiences into even smaller ‘niche markets’ on the other – makes issues of access to and participation in public discourse equally problematic† (pp. 343-344). Thus, this idea of an equal and democratic public sphere is difficult to have and carry out. In conclusion, the ideal public sphere tries to offer a place where people are able to discuss their ideas freely between one another. However, to believe that individuals can discuss in a completely free manner, with no influence and be complete equals, contributing on equal terms, is a far-fetched hope. There can only ever be a place of equality and rationality in an ideal society, as factors of social, linguistic and cultural inequalities, rights and even freedom of speech of an individual, all affect any possibility of equal communication and contribution between people in a public sphere.

Educational Psychology Essay Example | Topics and Well Written Essays - 2250 words

Educational Psychology - Essay Example Educational psychology is worried with the procedure of educational achievement in the middle of the universal population and sub-populations such as talented children and those subject to precise disabilities (Woolfolk, A. & Margetts, K. 2007). Scenario 1: He’ll Speak to his Brain Andrew was a very slow writer. He constantly stared into space and was easily distracted and yet didn’t admit he had a problem. Miss O’Brien has spoken to his previous teacher, who said he was lazy. Miss O’Brien believed that a lot of Andrew’s behaviour was linked to being afraid of getting it â€Å"wrong† and she had her suspicions that pressure came from home. She developed a strong relationship with Andrew and he eventually admitted to her that he had a problem with his writing. One day when Miss O’Brien was working with Andrew, she asked him why he couldn’t write what was in his head. He said, â€Å"When I get up to five things in my head they burst like a bubble - it’s like trying to pick up a bubble, when you touch it, it bursts.† It was a real insight into Andrew. He had just shown her how able he was at using and controlling language to capture his thoughts and feelings. He had identified his short-term memory problems. After that Andrew really unburdened himself saying that he was anxious that Mum and Dad might realise he has a problem and he believed himself that he couldn’t write. Together Miss O’Brien and Andrew devised three ways to help. First, they had a book of ideas which Andrew could carry around and when he saw or did something interesting he could make a note of it.

Prosopography - Assignment Example They also have a traditional leadership structure, where there is a council of religious leaders, specifically men, who makes decisions on behalf of the entire community. Additionally, this community tends to grow apple trees, cherry together with significant amounts of wheat. Majority of the Druze family tend to grow their own fruits, vegetables and bake their own bread. Druze women traditionally dress in long blue or white dresses with a white headscarf, while their men had abandoned their traditional modes of dressing, specifically the shirwal and grow moustache (Gordon, 12). Their houses are scarcely furnished, with a characteristic low wooden table and thin cushions lined against the walls. Their language has an Egyptian origin; their language can easily be recognized due to the fact that they have a sharp pronunciation of the letter â€Å"q†. Basically, the life of Druze man revolves around his family and attendance of religious meetings on every Thursday night. They hav e a high sense of hospitality in their culture and tend to visit each other in their homes (Gordon, 14). In regard to divorce, it is a rare action among the Druze; however, men may initiate divorce when a wife fails to bear children. Consequently, the Syrian Druze has a unique religion, which can be traced back to Egypt; in most cases, their Druze religion has been disavowed by Muslims (Gordon, 16). The Community had a positive relationship with the Assad regime, basically owing to the fact that Assad managed to seek tremendous support from the minority communities; however, currently the community is torn in between supporting Assad and the Islamist extremists. Some of the Druzes has claimed that Assad failed them by not providing them with weapons to protect themselves from the Jabhat Al-Nusra attacks (Gordon, 22). The Druze of Syria are poorer as compared to other minority communities; this has been attributed to the fact that they have spent many years on war issues rather than
