    This Strategic Guide on instant messaging is developed by ProcessOne, a company that delivers instant messaging services to businesses. The guide examines the real risks associated with instant messaging in corporate environments and explains how to mitigate them. ProcessOne argues that instant messaging is becoming a valuable form of communication in business environment, alongside the telephone and email. IM allows users to see if recipients are available to receive a message, thus it can be a much more efficient communication tool than email and telephone. The report suggests that danger arise when using public IM services like Gmail and MSN. Public IM services have not been designed for corporate activity and do not provide the level of security that is essential in a business environment. The report suggests different risk factors associated with public IM services as well as how businesses can overcome these risks. This guide is important as its attention is on security issues associated with instant messaging. A common concern among companies is that IM programs render their networks vulnerable to viruses and other potentially crippling intrusions (Glasner, J. 2002). ProcessOne suggests that the best way to reduce the risk of instant messaging is to bring IM in-house with the deployment of a central instant messaging server. IT departments can take measures to protect users and intellectual property through the use of encryption, anti-virus software, corporate policy, and domain certificates, thus the risks will be reduced.

    Skype is a free download which can be accessed from their website (www.skype.com.au). It is user-friendly, quick and easy to download. Once installed, minimal instruction is required to use Skype. Skype users can be located through searching the email address book, connecting through Facebook or inputting the username into the search box. Once connected with others, Skype has the ability to make audio calls, videoconference, share files and instant message. Video conferencing can be utilised throughout Skype with no charge. Skype allows users to see and hear others, which increases the effectiveness of the communication exchange. In Skype's recent update, screen-sharing functionality was added. This functionality enhances a videoconference by providing users with access to share one another's screens to view presentations or to assist with IT issues. Audio calls can be made between Skype accounts or through VOIP software to landlines or mobiles. The benefit of making calls through Skype is that they can be significantly cheaper than calling through a mobile or landline. Skype call charges start as low as $0.23c per minute. Credit for calls can be loaded onto Skype through the use of a credit card. Instant messaging allows users to talk to one another without the use of audio or video. It can be utilised when working on projects or for an alternative to video/audio in particular when Internet speed may not be high enough for a good connection. Instant messaging can be conducted with just one person or multiple people can use instant messaging simultaneously allowing for people to collaborate on projects. An extra benefit of Skype is file sharing, files can be shared instantaneously with no limit on the file size. This is a great benefit to businesses that may have size restrictions on their work email.

    Skype is an excellent software that both individuals and businesses can make use of. Skype's unified communications capabilities make it a useful strategic tool for businesses. While Skype has been successful in the consumer market, it may have had harder time cracking into business market as there are already several competitors. Skype likes to point out that more than 30 percent of its global user base uses the service for business. However, there have been speculations that a greater proportion of business use is overseas and that a much smaller percentage of "business users" have integrated Skype with their office systems (Blackwell, 2009). Blackwell (2009) suggests that the reason why not more businesses use Skype is that call and connection quality are not always as good as they are on public switched telephone network. As Skype works over the open, Internet and peer-to-peer technology help route calls, thus the service may not provide the quality sufficient for business use. Another concern is the security of the Skype service as it uses the public Internet for voice calls (Reardon, 2009). I think that the different collaborative opportunities Skype offers are valuable for small or medium-sized companies looking to keep costs down. Reardon (2009) believes that businesses in general won't get rid of their existing telephone service to use Skype, but some may use it to communicate with employees internally.

    I agreed that skype is an excellent tool, since it is user friendly and widely accessible. Apart from computer usage, it could also be accessed on smart phones, which it is a trend now and still growing on mobile phone usages. I felt that Skype had especially collaborated distant communication; as a student studying away from home country, a budget international communication tool like Skype is demanded. Yet the quality of calls is doubtable as Elin Frustol said, and I found this is a problem with most of online calling tools, such as msn messengers, tango and vibers. I believe that is not only the problem of the tool but also internet accessibility, and computer technology. These issues would need a longer time to fixed, and it may lead to broader usage such as business and government, however the question is would it still be a budget tool by then?

    This is a comprehensive blog entry introduction to the potential of Google Docs as a collaborative tool for students. These potential uses are also valuable in work places or other group work. The value of this resource is the well-written way Wetzel articulates the advantages of Google Docs for collaborative practice. His argument is that such a system, aside from being free, is valuable to go beyond the e-mail sharing culture to a full real-time collaborative environment. Wetzel then proceeds to give examples of the potential for the application of Google Docs in education contexts and classrooms. To summarise, he argues three main points in using Google Docs for collaboration:  The ability for Google Docs to provide instant feedback to students on their work  To conserve expenses on school projects such as printing costs  Encouraging the working together of students on a projects in a systematic and orderly manner The tone of the article is clearly very much in favour of using Google Docs for collaborative practice in educational settings. However, though this may not be an issue in educational contexts, there are disadvantages using Google Docs that are not reported. Two bloggers highlight those weaknesses which may be of concern when trying to use more features in Google Docs that are not there but are part of the Microsoft Office Suite:  The speed of internet connection is vital; if it is slow the collaborator may not be able to keep up with others' postings (Bukisa, 2011)  Most of the time you cannot work offline with Google Docs, you must be online to create and update documents (Creative Marketing Solutions, n.d.) However, the article does put a compelling list of features that make Google Docs a good system to use for educational collaboration.

    The article, Google Docs are a Free Online Educational Tool Written by David R. Wetzel gives a comprehensive overview of the benefits of Google docs specifically in relation to education. The article outlines these positives a few of these include (but are not limited to) the ability to secure the websites content, making it a safe place to upload work, the ability to comment and give almost instant feedback, the ability to update students on deadlines, information, and helpful tools and also to keep course content. It seems that these positives are quite a universal thing as Keith McPherson (2007) explored all of these benefits in his article new online technologies for new literacy instruction. This reminds me of the use of wiki's in education, a tool that is explored by Elisha Petersen (2009) in which the tool is used to do the same. This brings me to question, which is better? Why use one over the other, if they achieve the exact same thing? Wetzel's article doesn't seem to give any suggestion that the tool has anything wrong with it. Something that, in technology, is hard to believe. Keith McPherson, However, outlines a few limitations of the program. He states "the conversion of graphics and tables from a Word document to a Google document is not reliable and Google Docs does not run on older browsers and Safari or Opera" (McPherson, 2007). Ryan Spoon a Principal at Polaris Venture Partners writes in his blog that he decided to use Wikidot (a wiki platform) instead of Google docs, he believes that although Google docs are great for specific documents they "don't scale over time well… more importantly the documents are treated distinctly and ultimately get as cluttered as your computer desktop" so although two tools (wiki and Google docs) can inevitably achieve the same thing, they still work in very different ways, and one has to evaluate the finer details.

Government authoritatian Egypt revolution kill-switch internet

    The role any Government should play in regulating the Internet is certainly an intriguing argument. Having analyzed the liberating power of the Internet with particular regards to assisting revolutionary political collaborations in the western world (Fraser, 2008), it has become apparent that any attempt to restrict access to content or the internet itself only seeks to further the cause of these being oppressed. This is demonstrated throughout this paper with the uprising in Egypt and the documentation that the "internet shutdown only sought to incite the protesters more." Perhaps the most pressing issue presented from this paper is not only Mubarak's ability to shutdown the internet, but that similar scenarios have arisen across the Arab world and the political justification for large-scale shutdowns of the world wide web have all been fundamentally flawed. Moreover the desperate attempts from political factions to prevent online access, and the steps and methods employed to ensure a shutdown demonstrates just how significant the Internet has become from a governments perspective in empowering both the opposition and the individual leading to potential online collaboration in an attempt to cause political revolution. While there is perhaps too much focus on the technical aspects required to implement a shutdown throughout this article, the poor lack of justification for attempting to potentially kill the Internet within the western world is certainly pressing. While political collaboration online did not reach the same aggressive scale in relation to the situation in Egypt, the justification for a potential kill switch being solely based on a fear of online pandemics is certainly flawed and as Chen (2011) notes human presence will "most likely be a hindrance" in the face of a cyber emergency. Whether online terrorism will become a prominent threat in the 21st century remains to be seen but the justification for killing the internet in order to ha

    It seems rare that such a thorough and enlightening review would be found tucked away in the inside page of a global internetworking magazine. Thomas Chen has produced an excellent overview of the Mubarak Government's rationale in shutting down internet and mobile operators, as well as a world-wide evaluation of the relationship between the Government, private ownership sectors and the Internet. Weeks earlier Tunisia endured Internet control on a lesser scale, with the closure of news sites and political blogs, arresting news bloggers and were even "suspected of injecting hidden Javascript on certain Facebook pages to steal login passwords" (Chen, 2011). Chen tackles the difficult question 'What is the proper role of Government?' with the ease you would expect of a technology magazine's editor, questioning whether the Government is entitled to centralised control (quarantine) as though an online threat were a human pandemic such as SARS or swine flu. Mubarak's 'flicking of the switch' during the January uprising has ignited alarm over free speech in the United States. In 2010 a bill was introduced which suggested giving the President the ability to cut off "the nation's connection to the rest of the Internet during a time of crisis" (Lawson, 2011). At the time Senator Lieberman clarified that this so-called 'kill-switch' was for the safety of the American people, to disconnect them from international traffic 'in case of war' (Lawson, 2011). The idea that this switch is not only technologically possible but also a future prospect caused great concern. At the end of the day, did the 'kill-switch' work? The short answer is obviously "no", as the revolution continued during the blockage, Internet was returned after four days, and the Government fell after 17. However the long answer is far more complex. The existence of the 'kill-switch' technology reminds us that Government control and censorship of the Interne

online learning collaboration forum chat project

  • Novel way for using technology. By PETER LELONG, VINCE SUMMERS. 500 words31 July 2002Hobart MercuryMRCURY26English(c) 2002 Davies Brothers Limited STUDENTS in years 5 to 8 are helping to write a great online novel called Billy Bathtub. As confidence grows in the use of online learning technologies, we are seeing the range of activities made available for students continue to develop. The adventures of Billy Bathtub, supported by the Department of Education, is a topical case in point. Author Damian Morgan is currently engaged in writing a novel, online, in collaboration with Tasmanian students during second term. A teacher and writer for many years, Damian has been working with students from around the state in recent weeks. On the completion of the novel in August, Erica Wagner, a publisher with Allen & Unwin, will be editing the novel for publication. The contributions of the students who participated in developing the story will be acknowledged. The partnership of writer and editor in an online collaborative project with schools around Tasmania is certainly a new and innovative way of engaging students from years 5 to 8 in the writing process. With the completion of four drafts of chapter one completed, the author posted a number of questions on the forum to engage students to take an active part in writing the story with him. "I know this is the story of Will Reynes, but do I call him Will or do I call him I?" Morgan asks. One of the many responses which he received: "I think if the story is going to be written in the present tense it should be written in the third person, but if it is in the past tense, the first person. I personally find stories easier to read if they are written like that." The story revolves around the adventures of Will Reynes, who we first meet in chapter one as he tries to rescue his window-cleaning mother from a high-rise building, where she has become entangled in her safety harness. In chapter two, Will, is with his father in a frantic rush to the airport, to meet an important scientist who comes complete with a large ceramic elephant. Students involve themselves in the writing of the novel by submitting ideas through the Discover Education online forum. The author responds to the suggestions from the students. This interaction between author and reader in the development of a novel demonstrates a very good use of the technology. Schools can also engage in online chat sessions with the author by booking time with him over the web. Alternatively they can invite him to visit their classroom. The Discover web site provides a link to download the software, Microsoft Comic Chat, for the online chat segment of the project. Once configured this program provides a secure online environment for students to communicate with the author. The story will continue to unfold with contributions from students until the end of August. To take part visit the Discover web site at http://www.discover.tased.edu.au/ billybathtub/.

    Even though this article from The Mercury (Hobart) is nearly 9 years old, I believe that it is very interesting, and the first time that I have been aware of an online collaboration to write a children's novel. It also shows that online collaboration need not be complicated. Sometimes we overlook the simple in order to engage in the latest popular online trend or something that is seen to be technologically complex. This article shows how sometimes a simple online collaboration tool works best. The collaboration involved students from grades 5 to 8 and was coordinated by author Damian Morgan. Damian received a grant from the Tasmanian government to undertake the collaboration project. Collaboration for the project was undertaken in an online forum and through online chat sessions. Over a period of time students contributed and collaborated with Damian in order to write the novel. Collaboration can take many forms and often we don't realize that we are engaged in it, I suspect that the children in this project were having fun, learning and collaborating all at the same time and had little notion of it! It is interesting that access to the forum is still available and in fact it details the collaborative conversations between students and Damian. The forum is still available at the following URL: http://forum.education.tas.gov.au/webforum/student/cgi-bin/ultimatebb.cgi?ubb=forum;f=97 Final and draft versions of the novel are available at the following URL: http://odi.statelibrary.tas.gov.au/Resources/Framer.asp?URL=%2F2002%2F2%2F010%2Fdefault.htm&ID=00215534 References: Lelong, P.

    This resource directly links to my topic of crowdsourcing as it discusses a crowdsourcing project which involved young students having the ability to write a novel in a collaborative manner. Students were part of the process of writing 'The adventures of Billy Bathtub'. The article highlights some of the key benefits of crowd sourcing: non-professionals can make important contributions. Anyone can contribute, in this case, despite their age, their input was deemed valuable. It is important to consider that this project occurred in 2002; the nature of the online context was vastly different to today, and we can see this with the design/appearance of the project's online forum. In http://www.wired.com/techbiz/media/news/2007/07/creative_crowdwriting Gorski (2007) explored two popular examples of collaborative novel writing using crowdsourcing. 'A million Penguins' and 'These Wicked Games' also allowed a group of people to write the novel. However unlike 'The Adventures of BillyBathtub' they did not rely on a forum, but rather wiki technology and were also very open and allowed anyone to make edits. Due to this chaotic structure, i believe 'The Adventures of Billy BathTub' was more successful because it was more controlled and restricted. 'A million Penguins' and 'These Wicked Games' faced many issues including vandalism. Many contributors were also contributing content to chapters without bothering to read what was happening in the narrative. However as stated by Jeremy Ettinghausen (publisher of 'A million Penguins') the project was mainly a experiment to see what would happen if anyone could edit and write a novel (A Million Penguins - The More the Merrier, 2007). This article suggests that collaborative narrative writing can be successful if organizers implement some degree of crowd control and impose certain restrictions to avoid chaos, spam, and vandalism.

    Hi Kaye, thank you for your interesting article and comments. Following is mine: This article is a good example of how people use internet to communicate and collaborate, which is similar to one of my readings: The American Pain Foundation (APF) and The HealthCentral Network Collaborate to Develop Enhanced Internet Resources for People with Pain. Both articles explain how people are connected by Internet to share ideas, gain information, and interact with each other through a website. Both websites mentioned in these two articles are open for general users, such as year 5-8 students and patients with pain, who may not have professional skills on Internet, so these websites are designed to be simple and user-friendly. Such websites let users easily focus on gaining information and collaboration without technical issues. As Kaye (2011) claims, "a simple online collaboration tool works best". In addition, this article shows the trend of using Internet to improve learning efficiency and allows communication and collaboration after school. As students' contribution will be available to view once they enter it to the website, Internet not only makes collaboration across time and geographical boundaries by global networking but also encourages students to contribute to their projects with more flexibility. Furthermore, as students normally access to Internet at home, this makes learning in a more relax and intimate environment. As Pelton (1996) mentions, online learning allows students to move from a passive learning to an active learning mode. In short, online collaboration helps student to achieve learning goals more efficiently with powerful and user-friendly features. Reference: England, K. (2011).

    Thanks Jiawin and Cathy for your comments. It was a very interesting project wasn't it and I agree with you Cathy that one of the reasons that it was successful was probably due to the way it was controlled and organised - not like some of the examples in your readings (which were very interesting by the way). Jiawin - I read your articles too with much interest and would agree that the Internet is a powerful tool as it allows the sharing of ideas and information. Sometimes I think that people are afraid of engaging in some of these new online collaboration tools - but there is much to be gained by simply 'having a go'!! Thanks, Kaye
