¡mAbstract¡n This research examines six presses of Kaohsiung journalists', China Times, Liberty Times, United Daily News, Taiwan Times, Taiwan Shin Wen Daily News, and Public Daily News, the intra-organization media usage for Media Richness and Social Influence Model. It tests four media which are face to face, telephone, e-mail, and written document, and tests which one is suitable for Kaohsiung journalists use in formal communication and informal communication. The result is that the most journalist use face to face as their intra-organization media. Not only testing media usage, this research is also examining the prediction of media usage by Media Richness and Social Influence Model. The result is except downward communication media usage which lacks sufficient samples, the other communication flows' media usage prediction are Media Richness explanation of predicting media usage is better than Social Influence Model. For each press, face to face is the main choice for six presses' journalists in upward communication, horizontal communication and downward communication flow. However, United Daily News' journalists use written document as the main media in informal communication, but the other presses' still use face to face The finding in formal and upward communication, the prediction of media usage by Media Richness and Social Influence Model in Liberty Times doesn¡¦t have significant level. Meanwhile, Liberty Times and Taiwan Shin Wen News' prediction of media usage in horizontal communication don¡¦t have significant level. At last, there are only Liberty Times and Public Daily News's media usage prediction have significant level in informal communication. Keywords:intra-organization, media usage, face to face, telephone, e-mail, written document, formal communication, informal communication, upward communication, horizontal communication, downward communication, Media Richness, Social Influence Model.

This thesis concerns Social Network Analysis as a mechanism for exploring Community Dynamics. To be able to use the Social Network methodologies, relationships existing between the modeling entities are required. In this thesis, we use two different kinds of relationships: e-mails exchanged and co-authorship of papers. The e-mails exchanged, as an indicator of information exchange in an organization, is used to facilitate the emergence of structure within the organization. In this thesis we demonstrate the effectiveness of using e-mail communication patterns for crisis detection in a hierarchically set organization. We compare the performance of a Social Network based Classifier with some of the traditional classifiers from the data mining framework for inferring this hierarchy. A generic framework for studying dynamic group transformations is presented and the co-authorship of papers, as an indicator of collaboration in an academic institution, is used to study the community behavioral patterns evolving over time. Enron e-mail corpus and the IISc Co-authorship Dataset are utilized for illustrative purposes.

M. Tech. Business Information Systems / Although owners of Internet cafés extend the freedom to have Internet access to the community, they fail to tighten their computer security to safeguard the private information of their customers. This dissertation provides a conceptual framework for improving information security in the Internet Café, to help and ensure data privacy, data integrity, risk management and information security (IS) behaviour. The study investigated the information security issues that are faced by users of Internet cafés and explored the effects of these issues. The framework shows how users can improve their physical security to reach higher standards of information privacy over the Internet.

The advent of the Internet has generated a proliferation of online information-rich environments, which provide information consumers with an unprecedented amount of freely available information. However, the openness of these environments has also made them vulnerable to a new class of attacks called Denial of Information (DoI) attacks. Attackers launch these attacks by deliberately inserting low quality information into information-rich environments to promote that information or to deny access to high quality information. These attacks directly threaten the usefulness and dependability of online information-rich environments, and as a result, an important research question is how to automatically identify and remove this low quality information from these environments. The first contribution of this thesis research is a set of techniques for automatically recognizing and countering various forms of DoI attacks in email systems. We develop a new DoI attack based on camouflaged messages, and we show that spam producers and information consumers are entrenched in a spam arms race. To break free of this arms race, we propose two solutions. One solution involves refining the statistical learning process by associating disproportionate weights to spam and legitimate features, and the other solution leverages the existence of non-textual email features (e.g., URLs) to make the classification process more resilient against attacks. The second contribution of this thesis is a framework for collecting, analyzing, and classifying examples of DoI attacks in the World Wide Web. We propose a fully automatic Web spam collection technique and use it to create the Webb Spam Corpus -- a first-of-its-kind, large-scale, and publicly available Web spam data set. Then, we perform the first large-scale characterization of Web spam using content and HTTP session analysis. Next, we present a lightweight, predictive approach to Web spam classification that relies exclusively on HTTP session information. The final contribution of this thesis research is a collection of techniques that detect and help prevent DoI attacks within social environments. First, we provide detailed descriptions for each of these attacks. Then, we propose a novel technique for capturing examples of social spam, and we use our collected data to perform the first characterization of social spammers and their behaviors.

Thesis (MPhil)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: The Israeli-Palestinian conflict cannot be classified as an isolated conflict. Today’s clashes were not triggered by a single event, but rather are as a result of thousands of years of violent and at times restrained disagreements about the rights of Jews, Muslims and other ethnic groups to the disputed land known collectively today as Israel and the Palestinian Territories. This study examines the media coverage of one event during the conflict, i.e. the withdrawal by Israeli settlers from the Gaza area. The study tracks coverage over ten weeks in the South African media context, specifically the Mail & Guardian, Cape Times and the Sunday Times – a media setting in itself highly diverse and compelling. Using a qualitative framing analysis as the central methodology, the study focused on six core frames in analysing all articles/reports relating to the Gaza withdrawal. In addition, the editors of the respective newspapers were interviewed to complement the textual analysis. The methodological approach addressed how each story was packaged and presented, and then questioned why certain frames dominated and others did not. The study found that conflict (a combination of violent and non-violent) was the dominant frame chosen. Consequences and Attribution of Responsibility were the next two most prominent frames. Both these frames were found to apportion blame to a particular side in presenting the news reports and when providing comment. Whilst all three newspapers argued that they practiced a balanced coverage, it was this perceived “balance” in using several different frames of presentation that neglected a key “historical” frame. This lack of historical context was one of the key results of the other frames being so dominant. / AFRIKAANSE OPSOMMING: Die konflik tussen Israel en Palestina kan nie gesien word as ’n geïsoleerde konflik nie. Die huidige konflik is nie veroorsaak deur ’n enkele gebeurtenis nie, maar spruit uit die voortslepende geweld tussen Jode, Moslems en ander etniese groepe wat reeds duisende jare lank duur, as gevolg van betwiste aansprake op die grondgebied gesamentlik bekend as Israel en die Palestynse grondgebied. Dié studie ondersoek die mediadekking van een gebeurtenis in die konflik, naamlik die onttrekking van Israeli setlaars in die Gaza-gebied. Die studie volg mediadekking oor tien weke deur drie Suid-Afrikaanse publikasies, Mail & Guardian, Cape Times en Sunday Times. Met behulp van kwalitatiewe raming-analise as die sentrale metodologie, konsentreer dié studie op ses rame in die analise van artikels, wat verband hou met die onttrekking uit die Gasastrook. Die navorsing word aangevul met onderhoude met die redakteurs van die koerante. Die metodologie is toegespits op die manier waarop die stories verpak en aangebied word, en bevraagteken waarom sekere raamwerke oorheers en ander van minder belang is. Die studie bevind dat Konflik (’n samestelling van geweldadige en nie-geweldadige konflik) die oorheersende raam was waarbinne artikels in dié tydperk aangebied is. Die Gevolge- en Toeskrywing van Verantwoordelikheid-rame kom ná konflik die meeste voor. By albei raamwerke word bevind dat skuld aan die een of ander kant toegeskryf word in die aanbiedeing van nuusverslae en wanneer kommentaar gelewer word. Hoewel al drie koerante volhou dat hulle gebalanseerde dekking aanbied, word ’n belangrike “historiese” raam in dié aanbieding verontagsaam as gevolg van die gebruik van verskeie rame om balans te bewerkstellig. Die gebrek aan ’n historiese konteks is een van die vernaamste gevolge van die oorheersing van die ander rame.
