This article examines social movement leadership and how organizing tasks may be completed in online social movements.

Reconceptualizing collective action in the contemporary media environment

Collective action theory, which is widely applied to explain human phenomena in which public goods are at stake, traditionally rests on at least two main tenets: that individuals confront discrete decisions about free riding and that formal organization is central to locating and contacting potential participants in collective action, motivating them, and coordinating their actions.

The Geography of Semantic Information Spaces

The use of spatial metaphors to depict complex database content has become popular within the information visualization community to deal with the rapidly growing volumes of data. These spatialized database depictions are known as information spaces, or information worlds. Spatialization not only allows to visually summarize and describe complex data collections, but also provides opportunities for visual query and sense-making of large bodies of information.

Price Issues in Delivering E-Content On-Demand

The explosive increase in Internet bandwidth and usage opens a vista of opportunities to sell multimedia-rich software and services using the Internet. Once e-content is created, the cost of replication is negligible. Customers can download the e-content immediately after online transactions. Alternately, the content provider can stream the content to the customers. A sound business model is necessary for the success of such an enterprise. In this paper, we examine the determinants of revenue for an Internet based on-demand content delivery service.

Keyboards without Keyboards: A Survey of Virtual Keyboards

Input to small devices is becoming an increasingly crucial factor in development for the ever-more powerful embedded market. Speech input promises to become a feasible alternative to tiny keypads, yet its limited reliability, robustness, and flexibility render it unsuitable for certain tasks and/or environments. Various attempts have been made to provide the common keyboard metaphor without the physical keyboard, to build virtual keyboards.

The Laws of Cool: The Culture of Information

The Laws of Cool asks what the knowledge of the humanities has to offer in an age when knowledge is increasingly the business of corporate culture. When information technology is the means, and knowledge work, lifelong learning, or learning organizations the end, what do the

Pricing and Resource Provisioning for Delivering E-Content On-Demand with Multiple Levels-of-Service

Businesses selling multimedia rich software or e-content are growing in the internet. The e-content can be downloaded by the customer or alternatly, streamed by the content provider, immediately after on-line transactions. Since internet connection speeds are variable, ranging from dial-up access speeds to broadband speeds, the content providers may provide different levels-of-service (LoS) for the same content. If a provider offers service at different LoS, for example at 56 kbps, and 128 kbps, how should the price of the service be set such that the provider makes the most money?

Improving Speaker Training with Interactive Lectures

Feedback has always been a cornerstone of the learning process. Advances in mobile devices and wireless connectivity promise closer and better feedback between speakers and audiences. In this paper we discuss a system allowing both real-time and reflective feedback for speakers. By means of online video annotations the audience can augment a lecture with personal notes and give the speaker valuable feedback both instantaneously and retrospectively. The strengths and weaknesses of the system based on lecture hall experiments are presented and discussed.

The 11 Myths of Media Violence

The 11 Myths of Media Violence clearly explains why media violence has not only been allowed but encouraged to escalate. Esteemed author W. James Potter challenges many of our assumptions about the relationship between media and violence. He argues that these assumptions are the primary barriers preventing us from confronting the issue of violence in films, TV, and video games.

Using Computer Networking to Facilitate the Acquisition of Interactive Competence

The main thesis of this paper is that conducting class discussions on a computer network is an effective method for increasing the interactive competence of first-year foreign language learners because it provides students with the opportunity to generate and initiate different kinds of discourse. In addition, computer-assisted class discussion (CACD) allows students to play a greater role in managing the discourse, e.g. they feel freer to suggest a new topic, follow up on someone else’s idea, or request more information.
