A qualitative investigation into language education students' use of computer-mediated communication, this study reveals how the diversity, support and resources constructed through students on-line dialogue served to scaffold students' language and content learning. The study focuses on student interaction on an asynchronous bulletin board used as an adjunct to a graduate seminar. The radicals of persistent conversation (Bregman & Haythornthwaite, 2001) interacted with elements of the seminar design to facilitate non-native speakers' entry into the dialogue, while simultaneously affording all students with opportunities for exercising agency in their own learning. Relationships between native and nonnative speakers of English were altered by nonnative speakers' ability to communicate their competence, and participants developed a strong identity as a community. Diversity and community evolved as valuable contributors to individual learning.

This dissertation describes research which investigated the use of communication tools in a WebCT learning environment. The instrumental case study investigated the level and frequency of use of the web-based communication tools during a full-fledged course delivery at a university that enrols only full-time students. The unit of analysis was the case and the instruments included group interviews, observation anecdotal notes, communication diaries, focus group and a journal/logbook. A mixed qualitative and quantitative research method was used in this research. The study evaluated how the interactivity and not how either the lesson or the WebCT function. The conceptual framework focused on interactivity, features of communication tools that promote interactivity, as well as the domains such as cognition, motivation and learner interface as aspects that influence the use of communication tools. Various web-based tools were used by a sample consisting of a selected small group of IT students who participated in the study. Those communication tools were used to facilitate learning in WebCT. The results showed a total of 145 interactions for the duration of ten sessions. The WebCT communication tools supported either synchronous or asynchronous communication. Communication tools were used to retrieve information and send text-based messages to lecturers and students. Interaction at different levels was evident between student and student, student and lecturer, lecturer and student, lecturer and lecturer, as well as, student and content. In addition to the WebCT communication tools, students used extra web-based communication tools, to facilitate their learning. It was concluded that with continuous advances in information and communication technology and with ever increasing student numbers at resident universities, more tertiary institutions should offer on-line courses. More communication tools should be considered on WebCT to facilitate more interactive learning. / Dissertation (MEd (Curriculum Studies))--University of Pretoria, 2007. / Curriculum Studies / unrestricted

This project seeks to identify characteristics of successful online communities and apply them to designing and prototyping an online discussion forum where novice computer users can share computer questions and answers. Usability and sociability are identified as essential goals in the development of online communities. Appropriate and effective Computer Mediated Communication (CMC) software is evaluated and selected to run the discussion forum.

The diploma thesis deals with processing of determining the shear strength of concrete structures reinforced with composite reinforcement, subjected to shear force, according to five different design approaches. The theoretical part of the thesis is closely related to the project FW01010520 - "Development of bent composite reinforcement for environmentally exposed concrete constructions", which is realized at the Institut of Concrete and Masonry Structures, Faculty of Civil Engineering, Brno University of Technology. The project deals with the shear strength of concrete beams reinforced with steel and composite reinforcement in various combinations. Then the load-bearing results gained within the project are compared with the values obtained by calculations according to the solved design approaches and computer software Atena Science. The second part of the diploma thesis deals with the static design and assessment of the cell structure. The cell is designed as a room inside of the medical building, where is placed device of magnetic resonance which is the reason why the cell is reinforced with non-magnetic composite reinforcement.

This thesis examines the discourse strategies used to construct initiation schools in online media and message boards. The focus is on understanding the tensions that come with enacting traditional practices in the face of modernity and its associated cultural expectations. The thesis describes the manner in which these tensions are constructed in text by the media in news reports and participants in discussion forums. While there is still debate around whether the internet will revolutionise public participation and create a digital utopia; the internet is acknowledged as one of the widest reaching sources of information and entertainment. Specifically, the internet provides a platform to challenge the traditionally top-down communication between the elite, who have privileged access to the media, and the general public, who were previously constructed as passive recipients of information. Using the male circumcision initiation rite, this thesis examines how the South African public discursively constructs the epistemic location of African traditions in South Africa. The study drew on a sample of news articles from the News24 site, the largest news site in South Africa, ranging from January 2008 to December 2013. A corpus of 62 articles were analysed using the Critical Discourse Analysis technique described by Teun van Dijk. The findings of the thesis were that the initiation rite is used as a rhetorical tool to argue for the abandonment of African cultural practices in favour of modern, Western influenced beliefs and values. The findings also indicate that the initiation rite is reduced to the act of circumcision in the media by focusing on the injury and deaths of the initiates and excluding the meaning of the rite as a meaningful cultural practice. The conclusion of the thesis challenges the epistemicide committed against the male circumcision initiation rite from within the Decolonial school of thought, which critically examines everyday interaction for universalising, normative language that aims to commit cultural epistemicide to reinforce the white, male, European, Christian traditions of masculinity. / Psychology / D.

This dissertation examines how the major television networks, in conjunction with the Reagan administration, launched a lingering cloud of nuclear anxiety that helped to revive the Cold War during the 1980s. Placed within a larger political and cultural post-war context, this national preoccupation with a global show-down with the Soviet Union at times both hindered and bolstered Reagan’s image as the archetypal conservative, cowboy President that could free America from its liberal adolescent past now caustically referred to as “the sixties.” This stalwart image of Reagan, created and carefully managed by a number of highly-paid marketing executives, as one of the embodiment of peaceful deterrence, came under attack in the early 1980s when the “liberal” Nuclear Freeze movement showed signs of becoming politically threatening to the staunch conservative pledging to win the Cold War at any cost. And even if the nuclear freeze movement itself was not powerful enough to undergo the Herculean task of removing the President in 1984, the movement was compassionate enough to appeal to a mass audience, especially when framed in narrative form on network television. In the early 1980s, debates over the possibility of nuclear war and other pertinent Cold War related issues became much more democratized in their visibility on the network airwaves. However, the message disseminated from the networks was not placed in an educational framework, nor did these television productions clarify complicated nuclear issues such as nuclear winter theory and proliferation. I argue this renewed network attention on nuclear issues was not placed in an historical framework and likely confused American viewers because it routinely exposed audiences to both fact and fiction, undifferentiated at the level of the mass media.
