The Impact

Social networking has become one of the most popular communication tools to have evolved over the past decade, making it a powerful new information sharing resource in society. To date realising the potential of Social Networking Sites (SNSs) beyond their leisure uses has been severely restricted in a number of areas. This paper focuses on the application of SNSs in a learning environment and the impact this could have on academic practices. While undoubtedly, due to the very casual nature of social networking, there are serious concerns over how it could be integrated in a learning environment; the potential positive outcomes are many and varied. As a communication tool, its effectiveness is already manifesting in the millions who use these networks to communicate on a daily basis. So it is conceivable that educators should be able to create a learnscape - an environment for formal and informal learning - that adheres to educational guidelines, but also harnesses the social support system of these on-line communities. This paper examines the risks involved in the creation of this new learning ecology, and explores the challenges faced by both technology experts and teachers in delivering a truly innovative and effective new approach to education.

Use Of The Internet

The 2001 General Election generated considerable interest and also much criticism of politicians' use of the Internet. Via content analysis, search engines and database material, this article examines candidates' and local constituency parties' on-line activity in three areas: first, the extent of Internet use by candidates and local parties—who and how many candidates had live websites for the election?; second, the pattern of on-line activity at the local level—where were parties/candidates on-line?; and third, what were candidates doing on-line—did candidates experiment with interactivity, or use the new media as another top-down communication tool? The survey indicates that use of the Internet was patchy and websites often acted as little more than static on-line leaflets. Moreover, the overall impact of the Internet on electoral outcomes was minimal and use of the technology by itself is unlikely to herald the coming of e-democracy. However, we also argue that some of the criticism levelled at parties is misplaced and that there are good reasons why parties have so far behaved cautiously.

Electronic Technologies

The rapid evolution of electronic technologies is providing researchers, educators, and consumers increasingly fast access to information. On the Internet (Net), electronic mail is a rapid, efficient, and economical medium for communication. Mail list management software (Listserv, Almanac, Majordomo, and Liststar) now allows users with interests in specific topics to address production and marketing issues across state and international boundaries by posting messages to a discussion group (DG) at one electronic address. Replies from anyone interested in responding may be sent to the entire DG, constituting a discussion, or returned directly to the originator of the message. Three commodity-oriented, horticultural DGs—Apple-Crop, Veg-Prod and Direct-Mkt—established over the last 30 months now provide on-line forums for >600 subscribers from 46 states, 4 Canadian provinces, and 21 other countries. Twenty-seven percent to 31% of these DGs' subscribers responded to a survey evaluating the effectiveness of DGs as communication tools. Reponses showed that DGs were a valuable communication tool for reaching a broad resource pool rapidly and economically. Information requests, meeting announcements, and resource listings have dominated the activity of these DGs. Cooperative extension specialists and county agricultural agents represent most users (69%), followed by researchers (14%), farmers, and those with unlisted job descriptions (7% each). Ease of use, quickness (often within 24 hours), quality and quantity of replies, and the ability to glean timely information for files and newsletters were cited as the most important reasons for using these DGs.

Electronic Discussion Groups

Electronic discussion groups provide a forum in which to enhance the exchange of information between university researchers, extension agents and specialists, students, and their clientele; farmers, wholesalers/brokers, retailers and direct marketers as well as other colleagues in the same field. Three electronic discussion groups; Apple-Crop-Mg, Veg-Prod-Mg, and Direct-Mkt have been implemented and have been extremely effective in providing a unique forum for the sharing of knowledge. Over 400 subscribers are on-line with these groups from more than 30 states, four Canadian Provinces and three other countries. Participant surveys cite the ease of use, the timeliness of replies (often within 24 h), the ability to glean timely information for files and newsletters. These groups have been a valuable communication tool reaching a broad audience rapidly and cost effectively.

The term Internet memes was coined to describe the phenomenon of replicating and spreading messages via social media. This study explores individual personality traits in relation to Internet meme behavior in the context of online news about functional foods based on the expectancy-confirmation process, and also the correlates between value perception and consequential behavior. An online convenience sample was used to collect data by posting on LINE, the instant communication tool, and a total of 343 questionnaires were returned, 252 valid questionnaires were used for structural equation modeling and hypothesis verification. The results found that: (1) Neuroticism was positively related and Extraversion was negatively related to value expectation for consuming functional foods; (2) The food value for health expectation participants can predict replication and usage satisfaction; (3) The usage satisfaction and replicative behavior can predict the frequency of spread messages. The results suggest that consumers with Neuroticism will need to reduce processes of Internet memes to online fake news about functional food.

Higher education institutions are increasingly embracing the Internet as a tool to support academic courses and/or programs. Little research has been done to assess students' attitudes toward the Web-based instructions and communication tools that supplement academic courses and/or programs. The purpose of this study was to assess students’ attitudes toward the on-line asynchronous communication tool used as a required part of the MBA curriculum at a medium-sized university in the Midwest. The on-line asynchronous communication tool known as the Higher education institutions are increasingly embracing the Internet as a tool to support academic courses and/or programs. Little research has been done to assess students' attitudes toward the Web-based instructions and communication tools that supplement academic courses and/or programs. The purpose of this study was to assess students' attitudes toward the on-line asynchronous communication tool used as a required part of the MBA curriculum at a medium-sized university in the Midwest. The on-line asynchronous communication tool known as the MBA web-support/discussion forum is the nucleus of the interaction between students and faculty, and among students. It simulates the traditional classroom discussion activities among groups and between students and faculty. It also allows posing of course information, syllabi, office hours, and weekly assignments/activities. A Likert-type questionnaire consisting of 20 items was constructed and administered to 74 MBA students. The results of this study showed that respondents did not express high positive attitudes toward the on-line asynchronous communication tool. The discussion is focused on three elements that might be responsible for learners' attitudes toward on-line communication tool used to deliver Web-base courses or programs. These elements are on-line instructional design, building on-line community, and training. Recommendations are made based on the findings of this study.

The Fourier Transform

In the past few years on-line digital television frame store devices coupled to computers have been employed to attempt to measure the microscope parameters of defocus and astigmatism. The ultimate goal of such tasks is to fully adjust the operating parameters of the microscope and obtain an optimum image for viewing in terms of its information content. The initial approach to this problem, for high resolution TEM imaging, was to obtain the power spectrum from the Fourier transform of an image, find the contrast transfer function oscillation maxima, and subsequently correct the image. This technique requires a fast computer, a direct memory access device and even an array processor to accomplish these tasks on limited size arrays in a few seconds per image. It is not clear that the power spectrum could be used for more than defocus correction since the correction of astigmatism is a formidable problem of pattern recognition.

Minimum Distances

A Scanning Transmission Electron Microscope (STEM) was coupled to a small computer. The system (see Fig. 1) has been built using a Philips EM400, equipped with a scanning attachment and a DEC PDP11/34 computer with 34K memory. The gun (Fig. 2) consists of a continuously renewed tip of radius 0.2 to 0.4 μm of a tungsten wire heated just below its melting point by a focussed laser beam (1). On-line operation procedures were developped aiming at the reduction of the amount of radiation of the specimen area of interest, while selecting the various imaging parameters and upon registration of the information content. Whereas the theoretical limiting spot size is 0.75 nm (2), routine resolution checks showed minimum distances in the order 1.2 to 1.5 nm between corresponding intensity maxima in successive scans. This value is sufficient for structural studies of regular biological material to test the performance of STEM over high resolution CTEM.
