Full textAbstract:
Utilization of World Wide Web style Web-Based Intranet Systems (W-BIS) is a rapidly expanding information delivery technique in many organizations. Published reports concerning these systems have cited return on investment values exceeding 1300% and direct payback time periods as low as six to twelve weeks. While these systems have been widely implemented, little theoretically grounded research has been conducted in relation to users' acceptance, utilization or the perceived quality of these systems. The study employed a two-site investigation of corporate Web-Based Intranet Systems, with surveys distributed via the traditional mail system. The complete survey instrument distributed to employees included the ServQual/ServPerf, User Information Satisfaction, Ease of Use/Usefulness, and Computer Playfulness instruments. In addition to these previously developed instruments, the survey instrument for this study included measures of Web-Based Intranet Systems utilization and usefulness along with respondent demographics and subordinate-reported managerial commitment. This study investigated the reliability and validity of the ServQual/ServPerf instrument in an information systems service environment. The same analysis was conducted of the more generally accepted User Information Satisfaction instrument.

Full textAbstract:
The twenty-first century has found education at the crossroads of change. There are burgeoning challenges facing the modern educator. To rise to the importuning, educators find themselves turning to Information Technology for the answers. The technologies utilised in attempts to overcome the challenges often include the Internet and electronic educational resources. Although the Internet is not unduly called the Information Highway, it is also fraught with misleading and incorrect information. Educators’ arduous searches result in few good and useable resources. Thus, to store, organise and efficiently retrieve the discovered resources is a matter of time-saving. The aim of the study was to develop a method to organise and retrieve educational resources in an efficient and personalised manner. In order to do this, an exploration into pedagogy and educational paradigms was undertaken. The current educational paradigm, constructivism, proposes that each learner is an individual with unique learning and personal needs. To develop a new model, the current models need to be understood. The current solutions for the organising of educational resources are realised as several software packages, also called e-learning packages. A list of criteria that describes the essential requirements for organising educational resources was established. These criteria were based upon the pedagogical principles prescribed by educators and the practical technological frameworks necessary to fulfil the needs of the teaching/learning situation. These criteria were utilised to critique and explore the available solutions. It was found that although the available e-learning packages fulfil a need within their genre, it does not meet with the core requirements of constructivism. The resource base model seeks to address these needs by focussing on the educational aspects of resource delivery over an Intranet. For the purposes of storing, organising and delivering the resources, a database had to be established. This database had to have numerous qualities, including the ability to search and retrieve resources with great efficiency. Retrieving data in an efficient manner is the forte of the star schema, while the storing and organising of data is the strength of a normalised schema. It is not standard practice to utilise both types of schemas within the same database. A star schema is usually reserved for data warehouses because of its data retrieval abilities. It is customary to utilise a normalised schema for operational databases. The resource base model, however, needs both the storage facilities of an operational database and the efficient query facilities of a data warehouse. The resource base model, therefore, melds both schemas into one database with interlinking tables. This database forms the foundation (or the back-end) of the resource base. The resource base model utilises web browsers as its user interface (or front-end). The results of the study on the pedagogy, the current e-learning solutions and the resource base were written up within this dissertation. The contribution that this dissertation makes is the development of a technique to efficiently store, organise and retrieve educational resources in such a manner that both the requirements of constructivism and outcomes-based education are fulfilled. To this end, a list of technological and pedagogical criteria on which to critique a resource delivery technique has been developed. This dissertation also elaborates on the schema designs chosen for the resource base, namely the normalised schema and the star schema. From this schema, a prototype has been developed. The prototype’s function was two-fold. The first function is to determine the feasibility of the technique. Secondly, to determine the success of the technique in fulfilling the needs expressed in the list of criteria

Resumo: Este trabalho está baseado em uma experiência real, vivida no dia-a-dia do nosso trabalho na Empresa Brasileira de Telecomunicações S.A, EMBRATEL, quando da busca de ferramentas capazes de viabilizar o permanente treinamento dos Consultores Técnicos da empresa, localizados em diferentes partes do nosso país, em face da escassez de recursos financeiros e de tempo. Para tanto, iniciamos com uma retrospectiva histórica da Educação a Distância no mundo, seu presente e suas tendências visíveis. Depois, apresentamos uma descrição dos protocolos multicasting existentes, seguido de nossa proposta. Apresentamos, também, uma simulação usando o Simulador ns-2 de maneira a comprovar o correto funcionamento do protocolo proposto e avaliar seu desempenho. O núcleo desta tese é a proposta de um novo protocolo multicasting, elemento essencial para a otimização da rede de suporte, um imperativo para a eficiência de seu funcionamento e, principalmente, da diminuição de seu custo, tendo em vista a situação ideal de se transmitir voz e vídeo para garantir que uma aula a distância será o mais próximo possível de uma aula presencial, conforme aponta o resultado de pesquisas referenciadas no presente texto, uma vez que vídeo é uma aplicação que demanda grande largura de banda
Abstract: This work is based on a real life situation, experienced in our daily work at Empresa Brasileira de Telecomunicações S.A, EMBRATEL, when pursuing tools that would allow the continuous training of its staff of Technical Consultants. The Technical Consultants were spread all over Brasil, a country of continental dimensions. Time and cost were obstac1es to achieve the above mentioned training. This thesis starts providing a short account of the historical milestones on Distance Learning. We added considerations on the state-of-the-art and scenarios of future developments, which were drawn taking into account social and economical policies. Routing and existing multicasting protocols are described and compared with the bidirectional multicast protocol proposed in this thesis. The main purpose of this thesis is the proposal of a new Multicasting Protocol, to support a new concept on which a teacher can be a student on a different subject by taking into account that we aim a Distance Learning environment inside a corporation. The ns-2 Simulator is used to simulate the perfect operation of the proposed protocol and evaluate its performance. The use of video is mandatory in order to achieve a maximum efficiency at c1ass. The rapid switching of video transmission from the teacher to a remote student that asks a question (so that all other students spread around the country can also see who is asking) and back to the teacher is mandatory and is what motivated the development of this new Multicast Protocol

Full textAbstract:
The purpose and content of this work are to explore the proper strategy on how to deploy multi-service mobile net centric warfare, or FORCEnet, the Navy's concept for Net Centric Warfare. In this research, the author examined where the Navy Marine Corps Intranet (NMCI) fits into this vision and how it is mobile and multi-service compatible. It also explored how low-cost commercial approaches such as IEEE 802.11 wireless local area network technologies can be implemented as a joint notion of Net Centric Warfare in terms of a Service Oriented Architecture (SOA). The problem investigated in this study was to evaluate what cost savings and/or efficiencies were achieved by organizing and transitioning from a traditional network operation center to a managed services operation in the development of a wireless local area network (LAN) in a military setting. The military needs a road map on how to deploy wireless networks in a secure, supportable, and usable fashion that is in concert with the core mission of the military business requirements, i.e., a service oriented architecture. The research took place at several naval bases in San Diego. The methodology included the "case study," as described by Robert Yin (2003), and the systems development life cycle (SDLC). The expectation of the researcher in this study is the development of a managed services operation in the creation of a wireless LAN on a military base.

Este trabalho apresenta novas explorações do uso de sistemas agentes aplicados à proteção de sistemas elétricos de potência (SEP). Os sistemas agentes são definidos como softwares capazes de interagir com seu ambiente. Todos estudos apresentados focam o uso de agentes dentro de um SEP, através de uma rede privada de comunicação (intranet) baseada na tecnologia da internet. O objetivo final deste trabalho é o desenvolvimento de agentes que possam ser examinados em situações reais. Para facilitar esta tarefa, uma plataforma computacional foi desenvolvida denominada como EPOCHS (Electric Power and Communication Synchronizing Simulator). A principal função desta plataforma é permitir a integração dos agentes a um ambiente que combine simuladores que ofereçam informações sobre um SEP, assim como dados sobre uma rede intranet. Dentro deste contexto, um método para proteção primária e de retaguarda foi desenvolvido e testado dentro da plataforma EPOCHS. Os agentes desenvolvidos apresentaram resultados melhores que as técnicas tradicionais. Resultados ilustrando o desempenho e viabilidade deste sistema de proteção baseado em agentes são apresentados.This work presents new explorations into the use of agent technology applied to the protection of power systems. We broadly define an agent to be an autonomous piece of software capable of interacting with its environment. Our investigation centers on the use of agents within an electric power grid using a private communication network, termed a utility intranet, based on internet technology. Our goal is to create practical agents that can be examined in realistic situations. To facilitate this aim, a new platform has been developed, EPOCHS, which allows agents to operate in an environmental that combines proven electric power electromagnetic and electromechanical transient simulators with a popular network communication simulation engine. We developed primary and a backup protection system using agent technology and evaluated this system within the EPOCHS environment. The agent-based system studied improved on traditional methods. Results illustrating the performance and viability of agent-based protection system are presented.

Construir um sistema de informações para medir e acompanhar o desempenho de uma Organização complexa, sem fim lucrativo, na área social, é uma tarefa muito mais ampla do que simplesmente coletar e analisar alguns indicadores. Esta tese teve como objetivo o desenvolvimento e a análise do processo de implantação de um sistema de informações em uma Organização complexa (Febem/SP), visando dar apoio a uma administração mais eficaz. O processo de produção, tanto na área da saúde quanto na Febem, abrange todas as atividades desenvolvidas pelos profissionais no atendimento aos pacientes/adolescentes. Assim, o prontuário (registro das atividades da linha de produção) torna-se uma importante ferramenta para a avaliação deste processo. Objetivos deste sistema: construir a base de dados do adolescente autor de ato infracional, a fim de permitir um estudo pormenorizado da sua situação jurídica, social, educacional e de saúde, constituindo-se na base do sistema de informações da Febem/SP. Resultados: são apresentados a estrutura do conteúdo de informações, diagramas entidades-relacionamentos, diagramas de dados, exemplos das páginas da WEB, detalhes da rede, além da estratégia de treinamento e implantação utilizados. Aspectos éticos e legais do uso de dados pessoais em meio eletrônico são também abordados. São discutidas as dificuldades de implantação e operação deste sistema, suas semelhanças e diferenças com sistemas de informação em Organizações de saúde e é apontado o papel do médico informata. As principais dificuldades encontradas para a operação do sistema, até agora, referem-se à pouca experiência dos usuários com tecnologia de informação e resistência às mudanças organizacionais, principalmente quanto à implantação de um novo modelo de atendimento. O grande desafio, hoje, é a incorporação de forma eficiente e eficaz de toda esta tecnologia de informação existente à rotina dessas Organizações, com seu complexo sistema produtivo, compreendendo-se suas peculiaridades e limitações decorrentes de suas atividades fins.Development of an information system for monitoring the performance of a complex non-profit organization is a wider work than get and analyze some indicators. The purpose of this thesis was the development and analysis of the implementation of an information system in a complex organization (Febem/SP), aiming to support a more efficacious administration. The process of production in health organizations and at Febem/SP include all professionals activities for patients and adolescents care. Thus, the patient record (information recorded all through production activities) becomes an important tool for process quality assessment. System purposes: development of the delinquent adolescents information data base, enabling a better comprehension of their judicial, social, educational and health situation, becoming the basis for the information system of Febem/SP. Results: information set definition, entityrelationship diagrams, data diagrams, examples of WEB pages and NetWare configuration are presented. Implementation and users training strategy are also presented. Ethical and legal issues about personal data in electronic systems are commented. Difficulties for the implementation of this system and its operation are discussed; it is compared to health organizations systems, the role of the medical informatics professional is pointed. The main problems for this system operation, up to now, can be explained by the inexperience of the users in Information Technology and resistance to organizational changes, especially to a new approach to these adolescents reeducation. The challenge today is incorporating, efficiently and efficaciously, all these Information Technology in these organizations, with their complex process of production, recognizing their particularities and limitations.

Full textAbstract:
The aim of this thesis is to identify alternatives for the integration of smart cards into a classic Kerberos system. Some researchers have proposed specific solutions. Each proposal appeared to be limited and, hence, there was a need to identify what other approaches were available.
It was identified that smart cards can be added to each of the interfaces of Kerberos (user to authentication server, user to ticket granting server and user to application server). It appears most appropriate to use smart cards in the user to Authentication Server interface. The user's workstation is trusted with application data and so it will be usually appropriate for the application session keys to also be trusted to the user's workstation.
The smart card can be integrated into the user to Authentication Server messaging implementation so that the user's authentication information is never exposed to the workstation. Six options have been identified for the integration in this interface.
Some of the concepts developed were prototyped in order to identify the practicality of the suggestions. An early beta release of Kerberos from Massachusetts Institute of Technology was used as the base for prototyping.
It was found that complex protocols, such as Zero Knowledge Protocols, cannot be implemented on today's smart cards without special customisations by the smart card vendors. However, protocols that only required the use of common cryptographic functions such as DES (Data Encryption Standard) and RSA (Rivest, Shamir and Adleman) can be implemented.

M.Com. (Computer Auditing)Intranets and related technology, can be used to solve many problems in the local computing environment. But the use of the Intranet and the related technology also raises several control concerns. Because of the increased use of Intranets within the business environment, the internal control related to the Intranet has become an issue that needs to be addressed by management and the auditor. Computerization in the accounting environment has made it virtually impossible to audit around the computer. It is therefore essential that the auditor, and more specifically the computer auditor, should assess the influence of the Intranet on the audit objectives. The objective of this short dissertation is to evaluate the influence of Intranet technology on the audit objectives (within the Intranet's different spheres of application) in terms of the risks posed for the auditor and management. It was also aimed at identifying the security risks in relationship with the audit objectives...

Full textAbstract:
Successful enterprises are those that consistently create new knowledge, disseminate it widely throughout the enterprise and quickly embed it in new technologies and products. These ‘knowledge-creating’ enterprises understand what knowledge is and what they should do to exploit it. In other words, they successfully manage and share their knowledge throughout their enterprise. When launching a knowledge management initiative, it is important to identify which knowledge management processes are most relevant to the enterprise’s environment and systems, and steps should be taken to support these activities and integrate them into daily operations. Broader elements and issues should also be identified and recognised for the influence they have on the knowledge management process. For example that enterprises should encourage individuals to interact, to work together on projects, or to share their ideas on an informal basis and systems are needed to codify the knowledge of individuals so that others can use it. Applying these elements involves: information technology; formal and informal structures; and specific knowledge management tools. Another important factor in the success of a knowledge management project is to ground knowledge management and knowledge sharing within the context of the enterprise’s business strategy seeing that the intranet can assist in the creation of economic value and competitive advantage for the enterprise. The knowledge sharing or knowledge contribution part of the knowledge management process seems to be the most difficult for enterprises. Knowledge sharing often takes place in enterprises via employees’ informal networks. Knowledge management could turn this informal, ad hoc process into a more systematic process. Creating a corporate culture where knowledge is valued and shared effectively is a challenge. Part of the solution could be for an enterprise to be aware of their specific corporate culture and how it influences their behaviour and attitude towards knowledge sharing. Because the employee’s behaviour determines the sharing of knowledge, leadership has an important role to play and they could use various motivational practices to encourage knowledge sharing. Leadership should commit to creating an environment, within which employees are able to share, assess and experiment with new knowledge gained. The corporate intranet could be used as such an environment, but employees need to be trained to use their knowledge management IT tools, making it as easy as possible for employees to contribute to the enterprise knowledge base. Effective intranet usage should be embedded in the enterprise’s general corporate and knowledge sharing culture. The intranet should be seen as an essential part of the enterprise’s knowledge management system and should be designed to suit and enhance the enterprise knowledge sharing activities and culture. It is also important that intranets should be evaluated regularly to determine its current contribution to as well as future potential of the knowledge sharing capability of the enterprise. The importance of evaluating and measuring the enterprise intranet and various measurement tools were discussed in depth, which consequently led to the formulation of an intranet evaluation tool in the form of a questionnaire. The prototype questionnaire was compiled by using measurement tools developed previously. The questionnaire brought together the concepts of knowledge management, knowledge sharing cultures and intranet functionalities. The evaluation tool was then applied to measure the effectiveness of a management consulting business’s intranet in enhancing the enterprise’s knowledge sharing culture. Recommendations were made to enterprises use the questionnaire when using the questionnaire in similar environments. An intranet represents a tool of potentially high value to any enterprise, but in order to realise this value, the intranets should be properly measured and managed and every employee needs to take ownership and buy into the concept of the intranet as a knowledge sharing enabler. This calls for an employee to be motivated to participate in knowledge sharing, so that they can experience the value they could add and receive by using the intranet for knowledge sharing activities.Prof. P.A. van Brakel Mnr.

M.Sc. (Computer Science)Corporations throughout the world are facing numerous challenges in today’s competitive marketplace and are continuously looking for new and innovative means and methods of gaining competitive advantage. One of the means used to gain this advantage is that of information technology, and all the associated technologies and principles. These are primarily used to facilitate business processes and procedures that are designed to provide this competitive advantage. Significant attention has been given to each of the individual technologies and principles of Artificial Intelligence, Knowledge Management, Information Security, and Intranets and how they can be leveraged in order to improve efficiency and functionality within a corporation. However, in order to truly reap the benefits of these technologies and principles, it is necessary to look at them as a collaborative system, rather as individual components. This dissertation therefore investigates each of these individual technologies and principles in isolation, as well as in combination with each other to outline potential advantages, associated risks, and disadvantages when combining them within the corporate world. Based on these, the Intelligently Generated Knowledge (IGK) framework is outlined to implement such a collaborative system. Thereafter, an investigation of a theoretical situation is conducted based on this framework to examine the impact of the implementation of this type of collaborative system. The potential increase in cost savings, efficiency and functionality of corporations that would employ the IGK framework is clearly outlined in the theoretical example, and should this approach be adopted, it would be able to provide significant competitive advantage for any corporation.

M.Sc.Image Processing/Computer Vision and Computer Networks (in particular Intranets) may seem to have very little in common if one only looks at these fields of study superficially. In this dissertation we will look at some fundamentals and characteristics of Image Processing and examine them to see where the problem areas lie, focusing on the problem of computational requirements. We will also examine the fundamental characteristics of Computer Networks and Distributed Processing, looking for areas where we can potentially find a synergy with computational problems inherent in Computer Vision/Image Processing. To accomplish the goals stated above, the dissertation is divided into three parts. The first part examines Computer Vision and Image Processing and is followed by a section examining Distributed Computing models and Computer Networks. The final part is dedicated to suggesting a model to solve the problem of computational load associated with Image Processing. The aim of the model is to take advantage of and use the latent processing power available in an Intranet environment by distributing the processing among the machines on the network. The model is also intended to be flexible and to minimize the network load incurred by distributing the processing. In order to do so, the model is split into units that deliver specialized functionality in order to keep the components small and also to incur the minimum load on a specific machine.

M.B.A.Eskom, South Africa's electricity utility, is the electricity supplier for South Africa. It has 20 power stations with a nominal capacity of 39 154 megawatts. Eskom is among the top five electricity utilities in the world in terms of size and sales and strives to remain one of the lowest-cost producers of electricity in the world. Eskom supplies 98% of the country's electricity requirements, which amounts to more than half of the electricity generated on the African continent. Eskom supports the development of a Southern African transmission grod to encourage cooperation and accelerate economic growth in the region. Eskom support employment equity and encourages employees to develop to their full potential through training. Eskom sees itself as a respected corporate citizen and is working towards environmental sustainability and socio-economic improvement (Eskom report, 1997). The growth of Internet technologies (and within Eskom the Intranet) has been phenomenal. On 23 July 1998, after extensive consultation and compilation, an Eskom Internet / Intranet strategy was approved. The strategy defines the way in which Eskom will employ this technology to support their business, to ensure synergy in organisational efforts. This chapter gives an overview of the strategy (Eskom Report, 1997). The strategy positions Eskom to be able to derive significant business benefit. from the technology, and ensures we will not be "left behind" by our competitors and customers, but ensures that our use of the technology and the resulting costs can be properly managed. It accommodates the different cultures in the business groups, from progressive through conservative, in terms of the deployment of the technology ...

For example, corporate organisations are using portals or sophisticated websites to conduct electronic commerce via the web and provide access to both internal and external information resources and services, accessed via the Internet, intranets, and extranets. The view of the researcher is that innovative use of the Internet and web-based technologies, such as portals, should not be the domain of the corporate world alone. The focus of this thesis is, therefore, to establish the potential application possibilities of portals in other types of organisations, especially agricultural research organisations in the Southern African Development Community (SADC) region. The main research problem addressed in this thesis was What is the nature and application possibility of agricultural information portals in the provision of webbased, value-added information services for researchers? To address the above research problem, literature relating to the historical development of the Internet and the World Wide Web, intranet and extranet applications in organisations, as well as portals and their applications, was reviewed. In addition, a study was made of international trends regarding the provision of access to digital agricultural information resources and services via the web, and a questionnaire survey was conducted to establish whether it was necessary to use portals to provide access to digital-based agricultural information resources and services in agricultural research organisations in the SADC region. ii Resulting from the literature reviews, the study of websites of international agricultural organisations, and the survey on the need for portals in agricultural research organisations in the SADC region, the study established that: · There are several potential applications of portals in agricultural research organisations. This led to the definition of the nature and major components of the type of portal that could serve the needs of researchers in agricultural research organisations. · There is a need for portals in agricultural research organisations in the SADC region. The current use of the web in these organisations in the region is largely limited to the development of brochureware types of websites, providing access to information contained in the organisations’ brochures. Therefore, there is need to upgrade from basic Web sites to advanced sites or portals, and the study concluded that in this regard there is a need for clear guidelines to assist agricultural research organisations to plan the deployment of their information portals. Currently, most organisations are using ad hoc approaches when developing their Web sites. The dissertation, furthermore, develops the definition of an agricultural information portal as a web-based application that is accessed via the intranet or extranet and provides a personalised and adaptive interface that enables agricultural researchers to discover, track, and interact with colleagues and other people, software applications, information resources, services and tools relevant to their research interests and work. Taking into account the major components and definition of an agricultural information portal, the study proposes guidelines for use in planning the deployment of portals in agricultural research organisations. The proposed guidelines are independent of specific portal design or development methodology, application domains, and techniques.

For the past few years, the University of Natal has been using an HTML-driven InnerWeb as its intranet system. The advantages of database driven intranet technologies over static HTML pages are now well established. It was felt that the University should change to a database driven intranet system which would better serve the needs of the University community. The first part of this study was conducted to establish user perceptions and requirements of such an intranet. Results from this study suggested that the functionalities and needs expressed by participants are synonymous with functionalities offered by database driven intranets. The second part of this study was therefore to follow up and prioritise the identified requirements for the main intranet interface to establish a controlled vocabulary and investigate current debate on the possibilities and limitations of intranets as a knowledge management tool. Part of the study took cognisance of Stoke's use inspired research premise by adapting constructivist research philosophy as well as Van den Akker's development
research strategy to guide the study. Eclectic mixed methodology as suggested by Reeves guided the research design for this study. Thus data gathering methods which included group and on-line card sorting, semi-structured interviews, category membership expectation tests and prototype validation were used to validate each stage of the development process. Data analysis procedures included using Microsoft Excel to calculate the total score assigned to each item for possible inclusion on the intranet, cluster analysis using IBM EZSort software,
analysing interview transcripts using QSR NVlvo software as well as simple eye balling of the category membership expectation data. The initial 93 items for possible inclusion, which were identified at the first part of the study were reduced to 60 items. Some distinct themes, which were identified, include research activities, library, social notices, corporate notices, learning activities, University Policies and Procedures, student activities, staff
activities and on-line collaboration . The results of this study suggest that it is challenging to establish vocabulary which is common to the majority of prospective users. Thus, some of the suggested vocabulary for category labels did not have majority consensus. This study also suggests that participants expect a process driven intranet, which offers multidimensional access points and multiple ways to navigate. This implies analysing same data from different viewpoints. Participants want more from an intranet than simple document publishing though a few can not see the intranet beyond a document retrieval tool. The study suggests that users have different needs which could be better addressed by offering customisation and personalisation functionalities to suit users' individual needs. Participants expect to use the intranet as a reliable institutional memory which offers seamless remote
access to synchronous and asynchronous communicating tools, access to various forms of digital media, interactive on-line administration functionalities as well as access to on-line academic related activities.Thesis (M.A.)-University of Natal, Durban, 2003.

The selection of one medium of communication above another may appear to be a matter of personal choice, and of little research consequence. Yet, insight into media preference when it comes to receiving internal communication messages may mean the difference between effective communication and lack of communication within an organisation. A number of theoretical perspectives have been advanced to explain communication media choice decisions. For the purpose of this study, the Media Richness Theory (MRT) and the Symbolic Interactionism Theory (SIT) were used to explore media selection at the University of Pretoria (UP). The MRT is concerned with identifying the most appropriate medium in terms of "medium richness" for communication situations characterised by equivocality and uncertainty. The SIT concurs with the MRT, but goes further and predicts that situational determinants such as distance and time and the symbolic cues provided by a medium, also influence media choice. The hypotheses were tested with data obtained from 174 employees (academic and non-academic) based on the main campus of the UP. A mail questionnaire was used to gather data. The questionnaire was developed to test MRT and SIT predictions with regard to media selection. The gathered data were analysed to reach general findings from the descriptive statistics and to test the hypotheses by using inferential statistics such as (a) chi-square tests, (b) analysis of variance (ANOVA) and (c) factor analysis. Research findings indicate that employees at UP tend to select face-to-face media for highly equivocal messages and written media for clear, objective messages. The results also indicate that where situational constraints such as distance and time pressure are present, people tend to choose "leaner" media, such as telephone and computer-mediated communication media, irrespective of the contents of the message. When symbolic meaning is intended, however, such as a desire for teamwork and trust, a "rich" medium is preferred. These findings are in support of MRT and SIT predictions. The results from the factor analysis indicate that organisational culture in UP plays a more significant role than the communicator or recipient where media selection is concerned. Based on this research, it can be accepted (at a 95% confidence level) that:- media selection is determined by message equivocality, message uncertainty, situational constraints and symbolic meaning;
- there is no significant dependence between years service and media selection;
- there is a tendency to use computer-mediated communication media as much as or more than conventional media where messages of a non¬personal nature are concerned; this is, however not true for messages of a personal nature.r

M.Comm.This study was conducted with the intent of understanding and evaluating the commercial use and possibilities that the Internet offers, as well as the strategic approach businesses should take when commencing with electronic commerce on the Internet. The potential value of Intranets and Extranets has also been examined briefly. The Internet is a very useful mechanism for marketing as well as sales of products or services on a domestic or international basis. Various other commercial possibilities and uses exist for the Internet, as well as for its derivatives — the Intranet and Extranet. In the fiercely competitive market of today, companies research, develop and invest resources in various methods and tools in the hope to gain competitive advantage over their rivals. The Internet, Intranet and Extranet, used in isolation or conjunction, pose an extremely attractive alternative to gaining competitive advantage in a specific sector or market niche.The success of the Internet as a business tool depends directly on the overall business strategy that is driving the approach. For optimum success the main business strategy must be aligned with the Information Technology Strategy, and especially include thorough consideration as well as planning when implementing the Internet or one of its derivatives as a business tool.

M.Comm.The principal aim of the present dissertation is to determine the nature of an electronicbanking environment, to determine the threats within such an environment and the security functionality needed to ward off these threats. Security solutions for each area at risk will be provided in short. The main focus of the dissertation will fall on the security protocols that can be used as solutions to protect a banking system. In the dissertation, indication will also be given of what the security protocols, in their turn, depend on to provide protection to a banking system. There are several security protocols that can be used to secure a banking system. The problem, however, is to determine which protocol will provide the best security for a bank in a specific application. This dissertation is also aimed at providing a general security framework that banks could use to evaluate various security protocols which could be implemented to secure a banking system. Such framework should indicate which security protocols will provide a bank in a certain banking environment with the best protection against security threats. It should also indicate which protocols could be used in combination with others to provide the best security.

Full textAbstract:
This thesis develops a number of graph-based techniques that are capable of measuring the dynamic behaviour of a network and discusses their application in network management. By representing a computer network as a time series of uniquely labelled graphs, it is possible to measure the degree of change that has occurred between a pair of graphs, and hence the dynamics in a network. Concepts introduced include the median graph, intra- and inter- graph clustering, and hierarchical graph representations. The focus is on producing efficient algorithms and improved measures of network change. It is believed that these graph-based techniques for measuring network dynamics have great potential in network anomaly detection, and thus will improve reliability of enterprise intranets.

Introduction: Management of complex systems is facilitated through effective
information systems that provide real-time data to decision makers. For example,
instrument panels in airplanes ensure that pilots have well-designed feedback
concerning the status of mission-critical variables. Problem: While pilots have
dashboards for feedback and communication, healthcare executives may be
unaware of effective use of evidence-based guidelines within their healthcare
system. Purpose: The first objective of this research was to design and implement
an automated intranet dashboard reporting performance measures for a
geographically dispersed health system. The second objective was to describe how
this dashboard might increase cooperation and coordination for individuals and
organizations involved with healthcare delivery. Design: This research was
exploratory in nature, employing descriptive research approaches. A convenience
sample of healthcare executives completed a baseline survey at the start of the
study assessing levels of communication and cooperation. After three months of
exposure to the dashboard, participants were asked to complete a follow-up
survey. All visits to the dashboard were recorded in a web server log file.
Semistructured qualitative exit interviews were also conducted to explore reactions
to the dashboard, experiences with receiving outcome reports, and barriers to
communicating and coordinating with counterparts. Results: Descriptive analysis
of paired survey scores found substantial increases on a number of survey items,
suggesting that the dashboard contributes toward increased communication and
coordination for healthcare executives. This finding is balanced by the limited
rigor in the research design and an analysis of the web server log file, which found
few visitations to the dashboard by research participants. Qualitative data analysis
suggests that current reporting mechanisms are suboptimal for healthcare
executives and that one solution is the use of dashboards. Conclusion: This study
resulted in a number of important discoveries and avenues for further research. A
more rigorous research design is needed to explore the role of intranet dashboards
in healthcare settings.Graduation date: 2004
