Thesis (LLM)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: The monitoring of electronic communication is likely to face all employers sooner or later. The rapid advancement in technology aimed at helping to monitor electronic communication, makes it easier than ever before for employers to monitor the electronic communications of their employees. There are important questions to consider when dealing with the topic of monitoring electronic communication. Examples include "mayan employer legally monitor electronic communications?" and "how does monitoring affect the employee's right to privacy?" This thesis is an attempt to answer these and other related questions by analysing, inter alia, South African legislation, the Constitution and case law, as well as comparing the law as it applies in the United Kingdom and the United States of America. The analysis and conclusion offered in this thesis aim to provide theoretical consideration to academics and practical application for employers that are faced with the reality of monitoring electronic communications.
AFRIKAANSE OPSOMMING: Alle werkgewers sal waarskynlik die een of ander tyd met die monitering van elektroniese kommunikasie gekonfronteer word. Die snelle voortuitgang in tegnologie wat daarop gemik is om te help met die monitering van elektroniese kommunikasie, maak dit vir werkgewers makliker as ooit tevore om sodanige kommunikasies van hulle werknemers te monitor. Daar is egter belangrike vrae wat oorweeg moet word wanneer die onderwerp van monitering van elektroniese kommunikasie ter sprake kom. Voorbeelde hiervan is "mag 'n werknemer regtens elektroniese kommunikasies monitor?" en "hoe raak monitering die werknemer se reg tot privaatheid?" Hierdie tesis is 'n poging om hierdie en ander verwante vrae te beantwoord deur die ontleding van, onder andere, Suid-Afrikaanse wetgewing, die Grondwet en die reg soos deur hofuitsprake ontwikkel, sowel as vergelyking van die reg soos wat dit van toepassing is in die Verenigde Koninkryk en die Verenigde State van Amerika. Die ontleding en gevolgtrekking wat in hierdie tesis aangebied word, is gemik op die verskaffing van teoretiese oorweging aan akademici en praktiese toepassing vir werkgewers wat met die realiteit van die monitering van elektroniese kommunikasies gekonfronteer word.

Full textAbstract:
In the late 1990s, the Ministere de l'Education du Quebec (MEQ) undertook a reform program that would reframe the educational system. Technology and pedagogy were seen as needing realignment to better meet a student-centered, technology-driven, lifelong learning experience. The New Reform as this new framework is known will be fully implemented by 2008 and educators are its pivotal agents. With Information and Communications Technologies being central to the new reform, this qualitative study looks at educator use of the most widely used Internet application, electronic mail. Very little research has looked at how pervasive electronic mail has become among educators and how it is affecting their multidirectional, multilayered roles as educators. Data originate from respondent electronic mail, a literature review, and the author's personal experience. Outcomes, reached through inductive analysis, reveal that educators continue to experience difficulty manipulating electronic mail technology even though they appreciate its multiple advantages. How electronic mail can facilitate networked communication and educator teamwork to better translate the MEQ's new reform successfully is the focus of this study. Implications derived from the outcomes are discussed in view of enhancing ongoing contributions by Quebec educators.

Full textAbstract:
Prior research has examined entrepreneurial businesses spatially located in the physical or offline context; however, recent radical information and technological breakthroughs allow entrepreneurs to launch their businesses completely online. The growth of the online business industry has been phenomenal. Predictions for worldwide online sales estimate it to reach $2 trillion in 2016. Virtual entrepreneurship refers to the pursuit and exploitation of opportunities via virtual platforms. Web 2.0 cybermediaries offer web-based platforms that function similarly to traditional intermediaries in a virtual setting and minimize barriers to entry for virtual entrepreneurial firms. The use of such cybermediaries with increasing success suggests an implicit shift in the dominant logic that typically underpins the functioning of entrepreneurial firms operating in the physical world. In this relatively uncharted territory, marked by a focus on profit, cooperation, collaboration and community, three ideal-type institutional logics i.e. Market, Corporation and Community, blend together. It is posited that a Virtual Entrepreneurial Logic guides the norms, behaviors, and practices of entrepreneurial firms operating via these virtual platforms. This raises the question whether the blending of three ideal-type logics leads to the existence of different antecedents of performance. A business model antecedent addressing the economic dimension, a community antecedent addressing the community dimension and a co-creation antecedent addressing the collaborative dimension of the Virtual Entrepreneurial Logic were therefore empirically examined in this study. Thus, three research questions were investigated to explicate the antecedents. Primary data from 1396 virtual entrepreneurial firms was collected (business model antecedent n=366, community antecedent n=732 and co-creation antecedent n= 298) to test the proposed hypotheses. Results provided support for the three antecedents. This study makes important theoretical and practical contributions to understanding the domain of virtual entrepreneurship from a blended logics perspective. Using the theoretical lens provided by institutional logics helps shed light on the pivotal role played by cybermediary platforms in the Web 2.0 context. The primary role of synergistic effects, cooperative behavior, and collaboration have important implications for virtual entrepreneurship. Findings also contribute to other related streams in entrepreneurship such as microenterprises. The study offers theoretical extensions of prior work on co-creation to virtual small entrepreneurial ventures. From a practical standpoint, insights can help entrepreneurs to better understand and leverage performance drivers in virtual contexts in general and on cybermediary platforms in particular.

Novos equipamentos e tecnologias disponíveis no mercado vêm desempenhando papel crucial para o desenvolvimento e modernização do setor agrícola. A eletrônica e a automação têm-se mostrado cada vez mais importante e necessária neste processo de evolução, agilizando atividades, bem como reduzindo custos, principalmente aqueles associados à mão-de-obra demandada para execução de tarefas rotineiras. No contexto de irrigação verifica-se um objetivo comum referente à adoção de técnicas que propiciem a otimização da utilização de água pelas culturas, maximizando a eficiência dos processos de distribuição e aplicação de água e minimizando as perdas. Acerca disto, o conhecimento ou estimativa da vazão em um sistema de irrigação torna-se imprescindível ao se pensar em um plano de irrigação ou manejo de água eficiente. Existem diversos instrumentos e métodos de estimativa de vazão, cada qual com suas vantagens e limitações. Portanto, considerando um ideal de inovação tecnológica, foi proposto o desenvolvimento de um instrumento de medição de vazão utilizando dispositivos eletrônicos, de fácil utilização e baixo custo. Deste modo, este trabalho teve como objetivos: a) Desenvolver um medidor eletrônico de vazão utilizando célula de carga; b) Realizar testes hidráulicos e gerar uma equação matemática que represente a vazão instantânea em um conduto forçado, no qual o medidor estará instalado; e c) Determinar parâmetros de desempenho para o medidor desenvolvido. O experimento foi realizado no Laboratório de Hidráulica do Departamento de Engenharia Rural da ESALQ/ USP em Piracicaba SP. Desenvolveu-se um medidor de vazão que se enquadra na categoria de medidores do tipo força, no qual estão disponíveis opções de acesso a rotinas de medição, calibração e configurações. Na rotina de medição a leitura de vazão é atualizada aproximadamente a cada 7 segundos, sendo possível selecionar e alterar a unidade de exibição da vazão instantânea. O equipamento consta de uma rotina de calibração, na qual foi implementado o Método dos Mínimos Quadrados para definição de coeficientes de ajuste de uma equação de regressão ao conjunto de dados coletados nesta rotina. O procedimento de calibração do medidor foi desenvolvido com o objetivo de dispensar a necessidade de mão-de-obra especializada, bem como equipamento, computadores e métodos mais complexos e de difícil acesso. A tela de configurações permite observar e ajustar a equação de regressão utilizada, bem como ativar ou desativar a transmissão de dados via serial (RS-232) para computadores. O medidor proposto é capaz de operar na faixa de 7 a 28 m³.h-1 com erro máximo de ±1,4 m³.h-1 (±2,7%), sendo o coeficiente K de perda de carga localizada aproximadamente 0,55. Para as condições de estudo, a força de arraste máxima esperada sobre o conjunto anteparo-alavanca é próxima de 1,87 N, acarretando um esforço na célula de carga de até 3 N.New available equipments and technologies in the market are each time more important for the agricultural section development and modernization. The electronics and automation area have great value on this evolution, speeding up activities as well as decreasing costs, mainly those costs regarding with necessary labor to execute routine tasks. On irrigation there is a common objective of choosing techniques that optimize crops water use, increasing efficiency and reducing losses of water distribution and application processes. The flow metering in an irrigation system is indispensable stuff when an efficient water management is desired. There are many tools, devices and methods of flow metering each one with its respective features. Considering a technology innovation principle this work had the purpose to develop an electronic flow meter easy to use and low cost, using electronic devices. Nevertheless this research had the following objectives: a) An electronic flow meter development by using load cell; b) Hydraulics tests in order to determine a math equation that matches the instantly flow inside a pipeline; and c) Flow meter assess determining performance parameters. The research was done at Hydraulics Laboratory, Rural Engineering Department (Laboratório de Hidráulica - Departamento de Engenharia Rural), ESALQ/USP on Piracicaba-SP-Brazil. The developed equipment is based on drag force that a body experiences when immersed in a fluid stream. The flow meter developed has some screen options allowing user tasks definition like: metering, calibration, and make some internal configurations. In the metering task the flow value is updated on intervals close to 7 seconds being possible to select or change units showing flow results. The calibration task was developed to avoid or release the specialized labor need, equipments, computers or any sophisticated and complex method. In this task, it was implemented Least Square Method in order to calculate coefficients of a fitting equation. This equation was used to estimate flow from digital signals acquired from the electronic circuit. The configuration interface allows the visualization and change the fitting equation used by the system. It also allows the data transmission for computers by serial port (RS-232 protocol). The proposed flow meter is able to work from 7 to 28 m³.h-1 with uncertainty of ±1.4 m³.h-1 (± 2.7%). The coefficient of local head loss (K) was close to 0.55 for Reynolds number values higher than 105. In this work, the greatest drag force expected acting on the flat circular body and cylindrical object is about 1.87 N, resulting in a force on load cell up to 3 N.

Full textAbstract:
Thesis (MPhil (Journalism))--University of Stellenbosch, 2009.This study examines the history, development and diversity of news agencies. It studies the major agencies and pinpoints how smaller wire services that sometimes purvey niche news seek to offer a more diverse global news-flow. The linkage between news agencies and technological developments, and how wire services have helped advance technology, is examined since the first agencies began in the 1800s, up to the current era of the Internet. The rise of television and the subsequent ascent of the Internet prompted new demands for more diverse news procurement. This accelerated the convergence of different media and has exposed challenges and opportunities to news agencies, large and small. Alongside the telegraph, news wire services expanded from supplying news and information locally to being global players, helping the world shrink. The mediahistoriographical approach engages a critical examination of literature sources regarding the development of the major wire services, and some of the smaller players. The literature, along with interviews with news agency experts, provides the material to examine wire services. The study shows how some original agencies leveraged opportunities offered by their standing in powerful nations to become dominant transnational players. The ascendancy of the mega-agencies compounded limited news-flows from developed to poorer nations, while an expansion of diversified news-flows has not matched technological progression. This study concludes by recommending greater recognition of the importance of news agencies and more scholarly examination of them, as studies on them appear scarce compared to those on other media branches, such as newspapers, the electronic media and the Internet. More studies into the development of both mainstream and alternative news agencies would pave the way for a better understanding of how they function and could provide clues as to how they might be able to better sustain themselves as more diverse entities for the benefit of the public discourse. Through the above, this dissertation seeks to contribute, in a small way, to rectifying a knowledge disparity regarding a key component of the mass media, namely the news agency.

Carter, William R. "Incumbent Response to Radical Technological Innovation: the Influence of Competitive Dynamics on Strategic Choice." Thesis, University of North Texas, 2015. https://digital.library.unt.edu/ark:/67531/metadc804843/.
Full textAbstract:
Prior research on incumbent firm response to radical technological innovation identifies firm, technology, and environmental factors associated with incumbents’ performance after a technology shift. What remains unexplored are factors affecting choice of response made before a technological shift occurs. Such ex ante choices are important intermediate outcomes affecting long-term performance outcomes. Competitive considerations may be influential inputs in choice processes because technological innovation is often related to competitive strategy. The resulting research question for this study is: What role do competitive considerations play in incumbent firms’ ex ante strategic choices in response to potentially radical technological innovations? Findings from a survey of key informants in the electronics industry whose firms face a potential technological disruption (n=120) suggest that incumbents’ response choices are affected by competitor-related orientations and by perceptions of relative strength of their strategic assets. Limited support is found for a moderating effect of perceptions of the competitive environment. The results of this study extend theory on incumbent response to radical technological change by shedding light on the influence of competitor interdependence. Findings also suggest the importance of strategic choice as an intermediate variable in understanding incumbents’ long-term performance. Research examining choice factors at varied stages of a technology’s diffusion can further advance understanding of the evolving nature of strategic response choices and the effects they have on long-term performance.

Full textAbstract:
Thesis (MTech (Retail Business Management))--Cape Peninsula University of Technology, 2017.The growth and use of information and communication technologies (ICT) such as the Internet across the globe, has been phenomenal. For both businesses and consumers, the Internet birthed new and highly effective and efficient avenues for communicating and transacting. The use of the Internet as a business trading platform known as e-commerce became popular in the 1990s and has inevitably led to the mushrooming of online retailers. The growth of this non-store retail segment poses a threat to traditional brick and mortar retail stores, although retail experts now view online retailing as an evolution rather than a revolution. Previously, non-grocery merchandise was the predominant commodity that was being sold online, but there is now growing evidence of online grocery shopping (OGS). Most developed nations such as UK, USA, France and Finland are considered to have well-developed online grocery markets, yet developing countries such as South Africa are still at an infancy stage. Most research about OGS had a Eurocentric view, and there are limited studies that focus on other parts of the world such as Africa. This research study took a consumer-centric perspective to understand consumer adoption of OGS, with the specific aim of determining factors that influence consumers’ behavioural intention to adopt OGS in the Cape Metropolitan area of South Africa. This study followed a quantitative research approach and a statistically derived sample size of 455 respondents was used. These respondents were conveniently selected at shopping malls in the Cape Metropolitan area. Of the questionnaires that were distributed, 391 questionnaires were usable and were captured on Statistical Package for the Social Sciences (SPSS) version 23 for the purpose of data analysis. The findings of the study showed that most respondents were black single females aged between 26 and 45 years with a diploma education level. The study also showed that 84.9% (n=391) of respondents had not adopted OGS, which indicated that most respondents were still accustomed to in-store grocery shopping. Using the Generalised Linear Model to determine which factors influenced consumers’ behavioural intention to adopt OGS, only Perceived Cost (PCo) had a significant influence on consumers’ behavioural intention to adopt OGS. Other factors such as Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Visibility (VIS), Perceived Risk (PR), Perceived Image Barrier (PIB) and Social Attractiveness (SAT) had an indirect influence on consumers’ behavioural intention to adopt OGS. Based on the findings of the study in order to improve consumer adoption of OGS, the following recommendations have been made. Firstly, that online grocery managers and e-marketers should market OGS emphasising the usefulness and cost effectiveness of using it while at the same time factors such as PU, PEOU, VIS, PR, VIS, PIB and SAT should also be integrated into the communication campaigns. Secondly, that further research can be done to find ways that grocery retailers can use retain online grocery shoppers.

Full textAbstract:
Wikipedia is no longer just another source of knowledge about the world. It is fast becoming a central source, used by other powerful knowledge brokers like Google and Bing to offer authoritative answers to search queries about people, places and things and as information infrastructure for a growing number of Web applications and services. Researchers have found that Wikipedia offers a skewed representation of the world that favours some groups at the expense of others so that representations on the platform have repercussions for the subjects of those representations beyond Wikipedia's domain. It becomes critical in this context to understand how exactly Wikipedia's representations come about, what practices give rise to them and what socio-technical arrangements lead to their expression. This ethnographic study of Wikipedia explores the values, principles and practices that guide what knowledge Wikipedia represents. It follows the foundational principles of Wikipedia in its identity both as an encyclopaedia and a product of the free and open source software and internet freedom rhetoric of the early 2000s. Two case studies are analysed against the backdrop of this ideology, illustrating how different sets of actors battle to extend or reject the boundaries of Wikipedia, and in doing so, affect who are defined as the experts, subjects and revolutionaries of the knowledge that is taken up. The findings of this thesis indicate that Wikipedia's process of decision-making is neither hierarchical nor is it egalitarian; rather, the power to represent on Wikipedia is rhizoid: it happens at the edges rather than in the centre of the network. Instead of everyone having the same power to represent their views on Wikipedia, those who understand how to perform and speak according to Wikipedia's complex technical, symbolic and policy vocabulary tend to prevail over those who possess disciplinary knowledge about the subject being represented. Wikipedians are no amateurs as many would have us believe; nor are they passive collectors of knowledge held in sources; Wikipedians are, instead, active co-creators of knowledge in the form of facts that they support using specially chosen sources. The authority of Wikipedia and Wikipedians is garnered through the performative acts of citation, through the ability of individual editors to construct the traces that represent citation, and through the stabilization and destabilization of facts according to the ideological viewpoints of its editors. In venerating and selecting certain sources among others, Wikipedians also serve to reaffirm traditional centres of authority, while at the same time amplifying new centres of knowledge and denying the authority of knowledge that is not codified in practice. As a result, Wikipedia is becoming the site of new centres of expertise and authoritative knowledge creation, and is signalling a move towards the professionalization of the expertise required to produce factual data in the context of digital networks.

Today, both the way a story is told and how long the viewer's attention can be held are often as important as the story itself. This study shows how online media sets new standards for narrative and continues some print traditions. This study focuses on the dialogue between print and online media. A quantitative and qualitative analysis of this dialogue through story length, readability, shovelware and story packaging shows the numerous effects the Internet has had on news media content.

Full textAbstract:
Computer professionals have been agents of change in many organizations. In some cases the role inadvertently became theirs as they were the ones at the vanguard of implementing the new information processing technology in organizations. While in other cases they were the catalysts for change, to force new methods/procedures onto lethargic organizations. While introducing change on others in the organization and adapting to new technological changes themselves, the computer professionals have not really had to face a significant change in their status, power, or importance to the organization. The introduction of the personal computer has brought about significant change in the way the job of the computer professional is perceived by many in the business world. While this change is personally affecting the way they do their job, there has not been a noticeable attempt by those managing computer professionals to deal with the human emotions engendered by such a change. Part of the reason for this lack of attention may be due to the lack of a model as to how computer professionals react to change. Such a model would provide a system whereby it would be possible to recognize where efforts could be made to measure, predict, and modify situations so that a smooth transition can be made to the change. Toward this end a model was developed which presents a system as to how computer professionals react to change. This dissertation presents the model, surveys a population of computer professionals, and analyzes the model using data gathered from the population. The data was gathered in the form of a self administered survey which was given to computer professionals working for six investor owned electric and gas utilities in the Northwestern United states. They answered questions on a scale of from one to five as to their emotions and perceptions about the introduction of personal computers into their organizations. These questions spanned the timeframe as the organizations migrated from the early beginnings of personal computer introduction, to a situation where the use of personal computers was widespread in the company. In the case of three of the companies the personal computer had not yet achieved widespread use at the time of the survey. The data gathered from the computer professionals was statistically analyzed to see if relationships exist between the model and the data. Additionally, interesting demographic data was analyzed to see if certain other factors affected the computer professional's perception as to the impact of the personal computer on their quality of worklife.

Full textAbstract:
The primacy of the print novel as the main mode for knowledge dissemination
and communication is being challenged today by the vast influx and pervasiveness of
digital media. Print literature, then, is at potential risk for obsolescence, as digital
technology creates new modes of narrative distribution. The novel, therefore, is in the
midst of a metamorphosis, having to adapt in order to properly situate itself within the
new media ecology.
Somewhat paradoxically, the same digital technology that challenges print
literature’s primacy is responsible for the novel’s adaption. The changing face of the page
creates new novels that reflect the digital in print, through changes in typography, layout,
and design. These changes illuminate the need for a material-specific methodology in
literary theory, and brings about the death of postmodernism in the new, digital
environment.

Hillig, Mark Alexander. "Automated Channel Assessment for Single Chip MedRadio Transceivers." PDXScholar, 2013. https://pdxscholar.library.pdx.edu/open_access_etds/1005.
Full textAbstract:
Modern implantable and body worn medical devices leverage wireless telemetry to improve patient experience and expand therapeutic options. Wireless medical devices are subject to a unique set of regulations in which monitoring of the available frequency spectrum is a requirement. To this end, implants use software protocols to assess the in-band activity to determine which channel should be used. These software protocols take valuable processing time and possibly degrade the operational lifetime of the battery. Implantable medical devices often take advantage of a single chip transceiver as the physical layer for wireless communications. Embedding the channel assessment task in the transceiver hardware would free the limited resources of the microprocessor. This thesis proposes hardware modifications to existing transceiver architectures which would provide an automated channel assessment means for implantable medical devices. The results are applicable beyond medical device applications and could be employed to benefit any low-power, wireless, battery-operated equipment.

Full textAbstract:
The exponential growth of the Internet and other new technologies globally continues to re-shape the South African consumer and business landscapes. Media and entertainment group Johnnic Communications Limited has invested more than R1 billion in new technologies in the past 10 years alone. However, the company still has to realise the desired returns on this investment – a situation that is forcing management to review all its online activities. This research project sought to determine what the key success factors are for the local and international online media industry, with a view to recommending potentially viable Internet strategies that could turn around operations such as Johnnic Communications’ online offerings from being nice-to-have cost centres, into exciting and key profit-generating streams. The research found that while Internet offerings cannibalise the readership of printed newspapers in South Africa, new technologies also present media houses with the opportunity to tap into new and broader markets, and hence new revenue streams. To that extent, it concluded that continuing to invest in the Internet is an imperative for Johnnic Communications, rather than an option. In addition to recommending new digital strategies, the research also concludes that developing critical mass and having a clear online strategy are crucial factors towards the company making money out of new technologies.

Full textAbstract:
The primary focus of this research is an examination of the issues involved in the granting of access in an environment characterised by multiple users, multiple resources and multiple levels of access permission. Increasing levels of complexity in automotive systems provides opportunities for improving the integration and efficiency of the services provided to the operator. The vehicle lease / hire environment provided a basis for evaluating conditional access to distributed, mobile assets where the principal medium for operating in this environment is the Smart Card. The application of Smart Cards to existing vehicle management systems requires control of access to motor vehicles, control of vehicle operating parameters and secure storage of operating information. The issues addressed include examination of the characteristics of the operating environment, development of a model and design, simulation and evaluation of a multiple application Smart Card. The functions provided by the card include identification and authentication, secure hash and encryption functions which may be applied, in general, to a wide range of access problems. Evaluation of the algorithms implemented indicate that the Smart Card design may be provably secure under single use conditions and conditionally secure under multiple use conditions. The simulation of the card design provided data to support further research and shows the design is practical and able to be implemented on current Smart Card types.

Full textAbstract:
Voting enables certain formal decisions to be made through the participation of a given population; and it is the vital part of a democratic process. The method of voting used in South Africa (SA) today is derived from the Australian ballot system. This paper-based voting system, however, is slow, convoluted and inaccurate because of human errors; it is costly and largely inefficient. In the early 1900s, election officials overwhelmingly decided to use electronic voting (E-voting) systems to solve some of the problematic issues of paper-based voting systems. Mobile voting (M-voting) is a subset of E-voting; and it allows citizens to use their mobile phones to cast their votes. Very few countries have endeavoured to implement M-voting, in order to improve mobility and simplify the election procedures. Despite several M-voting initiatives reported worldwide; insufficient attention has been devoted to understanding the factors that influence the success or failure of M-voting implementation. It is also important to note that the implementation of M-voting may be very difficult; if the different modalities that aid successful M-voting implementation are not in place. This study seeks to develop a framework that has the potential to enable the successful implementation of M-voting in SA. The proposed framework is an IT artefact that endeavors to improve human experiences for voting. This study followed a Design-Science approach; and it made use of a case study to collect the data via a literature review, observations, questionnaires, focus groups and expert reviews. The study revealed that there is no institutional, legal and regulatory framework for the proliferation of M-voting in SA. Successful M-voting implementation depends on a compendium of factors, which may be unique in the local context where it is implemented. The framework that resulted from the above was assessed for validity and applicability; after which a modified framework was presented. The research concludes with specific implementation guidelines, as well as areas for future research.

Thesis (MBA)--Stellenbosch University, 2003.ENGLISH ABSTRACT: The effective application of the requirements of customer interface design is critical for the success of business-to-consumer electronic commerce ventures. The challenging environment experienced by South African-based business-to-consumer electronic commerce compounds the importance of offering Web sites with high usability and a conventional shopping experience. The first main objective of this study is to determine the requirements of customer interface design in business-to-consumer electronic commerce and is achieved through the review of the relevant literature. The second main objective is to measure the application of customer interface design within South African business-to-consumer electronic commerce. A thematic model (or framework) that represents the thirteen main requirements is developed. The model identifies the themes as transmission speed, page layout and structure, navigation, writing style, multimedia, customer support, customisation and personalisation, community, information, perceptions, trust and security, commerce, and the absence of errors. The model is used to subjectively measure the effective application of customer interface design in a test group of fifty South African-based Web sites. The third main objective is to present the results. Requirements that are effectively applied by most of the Web sites include the themes of transmission speed, page layout and structure, writing style, multimedia, trust and security and the absence of errors. The themes of navigation, customisation and personalisation, information, perceptions and commerce are evident, but applied less effectively. Although some sites do provide the theme of customer support, the overall result shows that it is generally not effectively applied. Community is the least effectively applied of all the requirements presented in the thematic model. Possible reasons for the results are offered, but further research is necessary to determine the underlying reasons for lack of the community theme. The relevance and the value of the study lies in the conceptualisation of customer interface design in South African business-to-consumer electronic commerce and the foundation presented for future research.
AFRIKAANSE OPSOMMING: Die effektiewe toepassing van klant-koppelvlak ontwerp vereistes is noodsaaklik om die sukses van besigheid-tot-verbruiker elektroniese handel ondememings te verseker. Die uitdagende omgewing vir besigheid-tot-verbruiker elektroniese handel in Suid-Afrika beklemtoon die belangrikheid van webtuistes om gebruikersvriendelik te wees en 'n konvensionele inkopie-ervaring te bied. Die studieprojek se eerste doelwit is om die vereistes van klant-koppelvlak ontwerp in besigheid-tot-verbruiker elektroniese handel te bepaal. Hierdie doelwit word bereik deur 'n oorsig van die relevante literatuur. Die tweede doelwit is om die toepassing van klant-koppelvlak ontwerp in SuidAfrikaanse besigheid-tot-verbruiker elektroniese handel te meet. 'n Tematiese model, wat dertien hoofvereistes saamvat, is ontwerp om meting te fasiliteer. Die model identifiseer die temas van deursendingspoed, bladuitleg en -struktuur, navigasie, skryfstyl, multimedia, klantediens, aanpassing en verpersoonliking, gemeenskap, informasie, persepsies, vertroue en sekerheid, handel, en foutloosheid. Die model is gebruik om die effektiewe toepassing van klant-koppelvlak ontwerp ten opsigte van vyftig Suid-Afrikaanse webtuistes te meet. Die derde doelwit is om die resultate te analiseer en te interpreteer. Vereistes wat meestal effektief toegepas word, is die temas van deursendingspoed, bladuitleg en - struktuur, skryfstyl, multimedia, vertroue en sekerheid, en foutloosheid. Die temas van navigasie, aanpassing en verpersoonliking, informasie, persepsies en handel is teenwoordig, maar minder effektief toegepas. Alhoewel sommige webtuistes die tema van klantediens bied, dui die verwerkte resultate daarop dat dit in die algemeen nie effektief toegepas word nie. Van al die vereistes, soos in die tematiese model saamgevat, is gemeenskap die swakste toegepas. Moontlike redes vir die resultaat word aangebied, maar verdere navorsing is nodig om die onderliggende redes vas te stel. Die toepaslikheid en waarde van die navorsing is gelee in die konseptualisering van klant-koppelvlak ontwerp in die Suid-Afrikaanse besigheid-tot-verbruiker elektroniese handel, sowel as die grondslag wat dit vir verdere navorsing bied.

Miniaturisation has been the holy grail of mobile technology. The ability to move around with our gadgets, especially the ones for communication and entertainment, has been what semiconductor scientists have battled over the past decades. Miniaturisation brings about reduced consumption in power and ease of mobility. However, the main impediment to untethered mobility of our gadgets has been the lack of unlimited power supply. The battery had filled this gap for some time, but due to the increased functionalities of these mobile gadgets, increasing the battery capacity would increase the weight of the device considerably that it would eventually become too heavy to carry around. Moreover, the fact that these batteries need to be recharged means we are still not completely free of power cords. The advent of low powered micro-controllers and sensors has created a huge industry for more powerful devices that consume a lot less power. These devices have encouraged hardware designers to reduce the power consumption of the gadgets. This has encouraged the idea of wireless power transmission on another level. With lots of radio frequency energy all around us, from our cordless phones to the numerous mobile cell sites there has not been a better time to delve more into research on WPT. This study looks at the feasibilities of WPT in small device applications where very low power is consumed to carry out some important functionality. The work done here compared two rectifying circuits’ efficiencies and ways to improve on the overall efficiencies. The results obtained show that the full wave rectifier would be the better option when designing a WPT system as more power can be drawn from the rectenna. The load also had a great role as this determined the amount of power drawn from the circuitry.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2015.In a quest to offer better services to both citizens and businesses throughout Africa, efforts to adopt e-government projects are gaining momentum. As a result of this, there is a need for effective measurement of delivery and quality of such e-services. Currently, there are several metrics applied to measure and rank the e-readiness of various African countries. However, while these measures have provided a source of comparative analysis between different e-government projects, they are far from being perfect. For example, most of these measures are diverse and difficult to compare, since they assume ‘one size fits all’ and ignore differing environmental, cultural and contextual factors of various countries. Further criticisms of these measures are that they are ‘first generation metrics’ designed for developed countries, as opposed to developing countries. Thus, the crux of the research problem was that there are no suitable evaluation strategies for understanding and measuring the effectiveness of e-government services in order to improve the management thereof, and thereby attain the best possible value for citizens. The objective of this study was to develop a framework, for evaluating the effectiveness of e-government services in a typical developing country. Tanzania’s mainland was chosen as the context for this study: as a typical developing African country, its early phase of e-government development provided an optimal case for this study concerned with the useful and effective evaluation of e-government services. I have chosen a qualitative research method paradigm, underpinned by an interpretive approach, to facilitate both research objectives: developing an evaluation framework after determining the necessary evaluation parameters. Empirical evidence was gathered via interviews with e-government practitioners in Tanzania and via focus groups with selected citizens. Other sources of data included government documentation (policies and strategies) and government websites. The data was analysed through the combined application of an adapted grounded theory method and interpretation. Using the latter analytical processes several effectiveness dimensions of e-government services were derived. Through further analysis these were synthesised into the main output of the study viz. an e-government citizen satisfaction framework (ECSF). This framework, a unique contribution to the existing body of knowledge, demonstrates how citizen and government imperatives should be amalgamated to evaluate the effectiveness of e-government services. The findings further support and advance Information Technology management within government, as this is the first comprehensive framework to ensure an integrated approach for monitoring and evaluating e-government programmes. This study also combines important ideas from two existing domains—service management and IS evaluation—to generate new foundations leading to further work by researchers.

Full textAbstract:
This thesis explored the potential of engaging gifted and talented learners in an online community of inquiry promoted by the use of asynchronous discussion forums. It employed a mixed-method, case-study approach where non-participant observation of online interactions and focus group meetings with the tutors contributed to the qualitative analysis of how the members realised participation in the forums. Quantitative analysis of membership data and online questionnaire responses revealed member characteristics of the sample members and patterns of active (vocal and silent) participation. Analysis was inductive and interpretive, informed by an original synthesis of the theoretical perspectives of two theories: the online learning theory suggested by Garrison, Anderson and Archer (2000); and the cognitive and affective domains for learning skills, proposed by Bloom et al. (1956) and Krathwohl et al. (1964). Content analysis of over 3000 messages posted or read by approximately 4500 members revealed community-based and ability-based characteristics that enabled the group to deal with social stigma, co-construct knowledge and promote meta- learning skills. The study concluded that participation in online discussion forums held the potential to address several of the needs identified by research for gifted learners: The need for the company of like-minded and similar ability peers; the need to develop higher order thinking skills; and the need to become independent learners. In this online network, the gifted learners could receive communal support from other members and tutors who acted as 'mentors' and role models for honing interpersonal and thinking skills such that they were motivated to pursue their interests to their full potential.

Full textAbstract:
The majority of SMEs have neither the internal expertise nor financial resources to enable in-house development of electronic commerce and therefore turn to the services of website design consultants to assist them. Unfortunately, they often engage consultants without any clear idea of their intended e-business strategy and without due care as to effective engagement processes. This frequently leads to ineffective e-business development and a highly disaffected group of small entrepreneurs. The study suggests that there is a significant gap between the intended strategies of SMEs and the actual e-business strategy implemented. The study aimed to investigate the relationship between Australian Small and Medium Enterprises, Internet strategy and the engagement of website design consultants. The objectives of the research project were firstly, to identify factors including SME engagement of website design consultants, and other factors presented in previous research that may influence the success of online organizations. Secondly, to construct a framework for analysing those factors' which may influence the success of online organizations. Finally, to provide a set of critical development factors that may be used by Australian SMEs to implement the online organisation. The research methodology chosen used an interpretivist perspective and incorporated a multiple cross-case study approach. Four research instruments were employed in the study to enable triangulation of data and to increase validity and reliability. A pilot study was conducted and the results were used to refine and develop the data collection methods, procedures and theory development for the main study. The expected outcomes of the research project included developing a framework to enhance negotiations between website design consultants and Australian SMEs; to design a set of critical development factors, in relation to Internet strategy and consultant engagement, that may be used by Australian SMEs and consultants to facilitate the implementation of the online organization; and to provide a summarised report to Dow Digital in fulfilment of the requirements of the research funding, and to publish a number of papers based on the research project.

Full textAbstract:
This paper explores the complex relationship between securing the rights of citizens to privacy and national security priorities under conditions of government mass surveillance. The inquiry examines the conflict between those who support and those who stand in opposition of government surveillance, and is framed around the question of whether changes in technology and the concept of nationalism help inform our understanding of the increase in surveillance post-9/11. From a peace and conflict studies perspective, the work analyzes how the rise of nationalism in the post-9/11 era and the protracted wars against terrorism, in combination with the growth of technological power, have impacted the relationship between state-surveillance and democracy. Findings identify protracted warfare, technology and corporate profits as conflict drivers within the surveillance system, which gives rise to moral dilemmas and structural polarizations in the political culture and institutions of the state and society. The analysis concludes that these dilemmas systematically create an imbalance of power between the citizen to the state, and cannot be fully addressed unless the efficacy of war is critically questioned.

Full textAbstract:
Information technology (IT) has become an integral part of the success and globalisation of business over the last two decades. It is hard to imagine how the efficiencies expected in today’s fast paced business world could possibly be achieved without the advancements in IT. The most significant of these advancements is arguably the advent of the Internet which has empowered businesses of all sizes by giving them the means to promote their products and services at a relatively low cost in markets that would previously have been inaccessible. The aim of this study was to assess whether e-commerce represents an alternative channel for a brick and mortar company wishing to follow a market penetration strategy. The study was based around a company, Canoa Eastern Cape, which trades in the office automation industry in the Eastern and Southern Cape of South Africa. The study investigated the history of Canoa Eastern Cape, focusing predominantly on the growth strategies followed by the business in the past. With a view to the future, growth strategies which could potentially be followed by Canoa Eastern Cape were also investigated. The result of these investigations was a recommendation that Canoa Eastern Cape should follow a market penetration strategy, which will see the business marketing its existing products within its current market by making use of a new distribution channel, more specifically e-commerce. In order to assess the suitability of e-commerce as a tool within a market penetration strategy a literature study was conducted to get a better understanding of ecommerce and its viability as business tool. The literature study focused on eight core concepts felt to be critical in the evaluation of e-commerce, namely: • the development of e-commerce over the past years; • the future of e-commerce; • whether e-commerce is a financial success or not; • requirements for e-commerce to be successful; iv • products that customers are prepared to buy online; • industries most affected by e-commerce; and • demographics of e-commerce users; and • e-commerce in the office automation industry. Using the information gained in the literature study as a basis from which to start, an empirical study was conducted. The objective of the empirical study was to obtain data which would be used to assess the level to which e-commerce has been adopted by consumers in the specific geographic area and whether these consumers are willing and able to make use of e-commerce as an alternative to conventional purchasing for the procurement of office automation consumables and office automation equipment. A quantitative research paradigm was adopted, making use of a structured questionnaire to gather information from the sample of Canoa Eastern Cape’s customers. The data collected from the empirical study were analysed using univariate and bivariate analysis. The findings of the empirical study suggested that: • demographics are a poor indicator of adoption of e-commerce; • there is a significant adoption rate within the sample: o 79.85 percent of the respondents reported to have used e-commerce before for personal use; and o 59.13 percentreported to have used e-commerce before for business use; • there is a high rate of willingness to use e-commerce again: o 91.09 percent of the respondents indicating that they would use e-commerce again for personal use; and o 80.18 percent indicating that they would use e-commerce again for business use; • there is a high likelihood that consumers will buy office automation consumables through an e-commerce channel, with 65.82 percentof the respondents indicating that they would be likely or very likely to buy consumables through an e-commerce channel; • there is no significant difference in the adoption rates between the three main areas within the targeted sample, that is, East London, Port Elizabeth and George and Knysna. Given the findings of the empirical study it is felt that an e-commerce solution does present a viable alternative channel for a brick and mortar company trading in the Office Automation Industry in the Eastern and Southern Cape wishing to follow a market penetration strategy.

ENGLISH ABSTRACT: This thesis is interested in textual features of websites which cover the same kind of content, but represent different organisations and address different kinds of audiences. Specifically, it investigates how information on HIV/AIDS is multimodally represented on the webpages of two non-governmental organisations (NGOs) and two governmental organisations. First, the websites of the national Department of Health and of a provincial Department of Health (Western Province) are scrutinised. Second, the websites of the Treatment Action Campaign (TAC) and Avert, NGOs with a special interest in the prevention and treatment of HIV/AIDS in southern Africa, are investigated. The aim of the research is to consider aspects of layout, the use of multimodality, and the introduction of selected themes and concerns foregrounded in the selected websites. The focus of the thesis is on the transmission of information, particularly through the electronic media, by investigating multimodal elements (language, images, sound, colours) and the layouts of websites, in order to identify possible interpretations which the intended audiences may afford the various texts. The analysis of the sites relies theoretically on the metafunctions developed by Halliday (1985) in his systemic functional linguistic framework. It also refers to an extension of Halliday’s work developed to allow multimodal discourse analysis that considers aspects of visual design and placement, developed by Kress and van Leeuwen (1996, 1998) and Kress (2003, 2005). These approaches focus on text, multimodal elements, the placements thereof on a page as well as the coherence between design of layouts and communicative modes that intend to send a convincing and meaningful message. The thesis also refers to Critical Discourse Analysis in that it considers matters of language and power in internet based communication. It seems that the governmental sites are set up with an audience in mind who needs to be informed on policy matters, while the NGO sites are set up with a more vulnerable audience in mind. One kind of web-communication is likely to alienate the exact people who should be receiving state support and treatment in the face of HIV/AIDS. Another is aimed more at supporting activism against the perceived lethargy of the state. A third supports various charities that reach out to communities where HIV-infection rates are particularly high. The interpretation of multimodal pages requires knowledge of website design for educational purposes as well as information on usage of the internet to get sufficient information. Further, access of the intended audience to electronic communication needs to be considered as this will determine whether the seriousness of the illness and possible prevention or treatment, is well communicated, especially to those who have been identified as most vulnerable to new infection. The thesis finds that electronic communication cannot be the first step to circulating information related to HIV/AIDS. Non-governmental and governmental institutions are still dependent on other forms of media than websites, thus on the printed media, radio and television, and on campaigns or community based projects to communicate with particular audiences. Electronic communication is complex in that it works with various modes (visual, verbal, audial) and requires some technical sophistication from producers and receivers of texts. Theories of communication and discourse analytic methodologies can assist in our understanding of how the internet succeeds or fails in circulating critical health care information. However, to gain a reliable understanding of how the internet functions in transmitting HIV-information to all interest groups, received knowledge of other areas of scholarly interest in health care communication, such as multilingualism, sociology, anthropology, behavioural sciences, cognitive psychology or brain research elaborations, would eventually have to be considered as well.
AFRIKAANSE OPSOMMING: Hierdie tesis stel belang in tekstuele kenmerke van webwerwe wat dieselfde tipe inhoud weergee, maar verskillende organisasies verteenwoordig en verskillende tipes gehore aanspreek. Dit ondersoek spesifiek hoe inligting oor MIV/Vigs multimodaal op die webbladsye van twee nie-regeringsorganisasies (NRO’s) en twee regeringsorganisasies aangebied word. Die webwerwe van die Nasionale Departement van Gesondheid en die Provinsiale Departement van Gesondheid (Wes-Kaap) word eerstens noukeurig ondersoek. Tweedens word die webwerwe van die Treatment Action Campaign (TAC) en Avert, NRO’s met spesiale belang in die voorkoming en behandeling van MIV/Vigs in suidelike Afrika, ondersoek. Die doel van hierdie navorsing is om oor aspekte van uitleg, die gebruik van multimodaliteit en die invoering van spesifieke temas en sake wat op die geselekteerde webwerwe beklemtoon word, na te dink. Die tesis se fokus in op die oordrag van inligting, veral deur die elektroniese media, deur multimodale elemente (taal, beelde, klank, kleur) en die uitleg van webwerwe te ondersoek, om sodoende verskillende moontlike interpretasies wat die bestemde gehoor aan die verskeie tekste mag heg, te identifiseer. Die analise van die webwerwe steun teoreties op die metafunksies wat deur Halliday (1985) ontwikkel is in sy grammatikale raamwerk, Systemic Functional Grammar. Dit verwys ook na ’n uitbreiding op Halliday se werk, wat deur Kress en Van Leeuwen (1996, 2005, 1998) en Kress (2003) ontwikkel is om multimodale diskoersanalise toe te laat wat aspekte van visuele ontwerp en plasing oorweeg. Hierdie benaderings fokus op teks, multimodale elemente, die plasing daarvan op ‘n bladsy en die koherensie tussen die ontwerp, uitleg en kommunikatiewe modusse. Dit kyk na hoe hierdie elemente saamwerk om ’n oortuigende en betekenisvolle boodskap uit te stuur. Hierdie tesis verwys ook na aspekte van Kritiese Diskoersanalise wat betrekking het op kwessies van taal en mag in internetgebaseerde kommunikasie. Dit kom voor asof die regeringswebwerwe ontwerp is met ’n gehoor in gedagte wat oor beleidskwessies ingelig moet word, terwyl die NRO-webwerwe ontwerp is met ’n meer weerlose gehoor in gedagte. Lg. gehoor word ingelig oor die siekte en behandelingsmoontlikhede eerder as beleid. Een soort web-kommunikasie sal waarskynlik dié mense wat juis regeringsondersteuning teen MIV/Vigs behoort te ontvang, vervreem. ’n Ander soort is meer daarop gerig om aktivisme teen die staat se vermeende traagheid te ondersteun. ’n Derde soort kommunikasie ondersteun verskeie liefdadigheidsorganisasies wat uitreik na gemeenskappe waar MIV-infeksiekoerse besonder hoog is. Die interpretasie van multimodale webwerwe vereis kennis van webwerf-ontwerp vir opvoedkundige doeleindes asook inligting oor die gebruik van die internet om voldoende inligting te bekom. Verder moet die bestemde gehoor se toegang tot elektroniese kommunikasie in ag geneem word, aangesien dít sal bepaal of die erns van die siekte en moontlike voorkoming of behandeling, goed weergegee word, veral aan dié wat s besonder blootgestel is en dus hoë risiko loop vir nuwe infeksie. Die tesis bevind dat elektroniese kommunikasie nie die eerste stap kan wees in die proses om inligting oor MIV/Vigs te sirkuleer nie. Nie-regerings- en regeringsorganisasies is steeds afhanklik van ander media as webwerwe, soos drukmedia, radio, televisie en veldtogte of gemeenskapsgebaseerde projekte, om met bepaalde gehore te kommunikeer. Elektroniese kommunikasie is kompleks omdat dit met verskeie modusse (visueel, verbaal, oudio) werk en tegniese sofistikasie van vervaardigers en ontvangers van tekste vereis. Teorieë van kommunikasie en diskoersanalise-metodologieë kan ons insig in hoe die internet daarin slaag (of nie) om belangrike gesondheidsorginligting te versprei. Om egter ’n betroubare begrip vir die werking van die internet as verspreider van MIV-inligting aan alle belange-groepe te verkry, moet kennis van ander areas van belangstelling in gesondheidsorg-kommunikasie, soos veeltaligheid, sosiologie, antropologie, gedragswetenskappe, kognitiewe psigologie of brein-navorsing, ook uiteindelik oorweeg word.

Master of Technology: Business Information System
In the Faculty of Business
At the Cape Peninsula University of Technology, 2013The South African manufacturing industry landscape has changed due to the pressures of globalisation and liberalisation of trade policy regimes. The structural shift of this industry has led to a global market in which many small businesses in the manufacturing sector find it difficult to compete with competitors for example, in Asian countries. Companies are required to improve their competitiveness by using various strategies such as e-commerce. However, these strategies are changing economics, markets, industry structure, products and services, the flow of products and services, consumer segmentation, consumer values, consumer behaviour and labour markets. An e-commerce strategy could assist small businesses in emerging markets to streamline their business processes in their respective sectors and industries, thus enabling them to enhance their business activities. Yet, literature reveals that most SMMEs do not take full advantage of e-commerce applications in their business activities. A qualitative approach using a case study methodology is used for this research. The researcher adopted models such as the Technology-Organisational-Environmental model, a value proposition model and a key assets model to collect and analyse evidence to propose guidelines for e-commerce initiatives in the selected environment. The findings indicate that SMMEs could improve their performance by establishing formal strategies and structures to increase their worth. This is done by creating e-commerce strategies to fit their organisational goals and objectives. Furthermore, manufacturing SMMEs need appropriate online platforms to transact and build strong relationships with suppliers, customers and partners. In addition, it is essential for SMMEs to establish and monitor quality standards in their e-commerce activities. It was found that the key assets needed by SMMEs in the manufacturing sector could impact their ability to sustain their business activities. Finally, manufacturing SMMEs need to deliver targeted and contextual marketing messages to help influence potential decision makers. This research contributes to the field of e-commerce by providing guidelines which manufacturing SMMEs could use as a starting point, to understand and improve their current e-commerce strategies and sustain their business growth.

The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

Thesis (MPhil)--Stellenbosch University, 2003.ENGLISH ABSTRACT: The modern correctional agency is characterised by the extensive use of information and communication technology (ICT) (e.g. computers, close-circuit television cameras, electronic monitoring systems) and human sciences technology (HST) (e.g. psychometric tests, therapy and educational programmes) to monitor, discipline and rehabilitate sentenced offenders inside and outside of institutions and to prevent their recidivism. As a result of this combination of ICT and HST, modern correctional institutions were transformed into socio-technical environments with serious implications for the relationships between those within and outside of the institution. The use of ICT for continuous monitoring of the prison and its population, has resulted in a situation where correctional officials, like prisoners, have become legitimate datasubjects. In addition to the privacy dilemma that resulted from this, continuous monitoring has also negatively affected the relationship between the state and those under surveillance (inmate, parolee, family of parolees and correctional officials). The utilisation of sophisticated technology by organisastions to achieve certain key objectives, does not necessarily bring about the desired results. Pistorius (1996) is of the opinion that only organisations who are true learning organisations will benefit from the use of such technology. This study aims to integrate all of these perspectives in order to determine the impact of technology on a single South African correctional institution.
AFRIKAANSE OPSOMMING: Die moderne korrektiewe agentskap word gekenmerk deur die omvangryke gebruik van gevorderde inligting- en kommunikasietegnologie (IKT) (bv. rekenaars, geslotebaan televisiekameras en elektroniese moniteringstoestelle) asook geesteswetenskaplike-tegnologie (GWT) (bv. sielkundige toetse, opvoedkundige en terapeutiese programme) om gevonnisde oortreders binne inrigtings en in die gemeenskap te moniteer ten einde hulle te rehabiliteer en hul terugval in misdaad te voorkom. Die kombinasie van GWT en IKT binne die gevangenis het gevolglik daartoe bygedra dat die moderne gevangenis tot In sosio-tegniese omgewing omvorm is met bepaalde gevolge vir die verhouding tussen gevangenes en korrektiewe personeel. Aangesien IKT meesal vir deurlopende monitering van die inrigting en diegene daarbinne gebruik word, word korrektiewe personeel net soos gevangenes, legitieme datasubjekte. Hierdie monitering oor die algemeen, skep 'n privaatheidsdilemma met bepaalde implikasies vir die verhoudinge tussen die gemoniteerde (gevangenes, geparoleerdes en hul families, korrektiewe personeel) en die staat. Die ontplooiing van gesofistikeerde tegnologie ter bereiking van 'n organisasie se sleuteldoelwitte, lewer egter nie outomaties die verwagte resultate nie. Pistorius (1996) argumenteer dat die optimale benutting van tegnologie slegs moontlik is in lerende organisasies. Hierdie studie poog dus om al hierdie sake te integreer teneinde die impak van tegnologie op 'n enkele Suid Afrikaanse gevangenis vas te stel.

Since the emergence of the Internet, scholars have had mixed opinions regarding its role in influencing levels of political participation. Two frameworks, the mobilization and the reinforcement theses, were created from these opposing views. The introduction of social networking websites (such as Facebook) offers new platforms with which to test these opposing theories on.
This study investigates the Facebook group ―Canadian‘s against Proroguing Parliament,‖ to determine: 1) what the members' motivations were for participating in the group, 2) whether the group attracted formerly marginalized voices to participate on the group, or simply reinforced those who were already active in the political process, and 3) whether the participation of members on the group translated into offline or real world political participation. The findings suggest that the group‘s members had a variety of reasons for joining the group. As well, the findings suggest that the group both mobilized reinforced its participants. Finally, the data indicates that in some instances, the group‘s members translated their online participation into real world political activity.171 leaves ; 29 cm

Introduction - Literature review -- Online word-of-mouth: a comparison of American and Chinese discussion boards -- Electronic word-of-mouth: a comparison of stated and revealed behaviour on electronic discussion boards -- A cross-cultural comparison of electronic word-of-mouth and country-of-origin effects -- Conclusion.
The growth of electronic discussion boards has enabled consumers from different cultures to communicate with people of similar interests. Through this online channel, marketing concepts such as word-of-mouth (WOM) and country-of-origin (CoO) effects have the potential to become more important because of the potentially large number of participants involved. The US and China, being the largest and second-largest online population in the world respectively, are ideal countries to investigate the frequency and extent of these marketing concepts. --The thesis consists of three separate but inter-related papers which have been published in journals or have been accepted for publication. Each paper builds on the one before and analyses different aspects of online consumer behaviour such as information-giving, information-seeking and the CoO statements made by participants of discussion boards. By examining and comparing the frequency and content of discussion postings on discussion boards within US and China based websites, the thesis makes a comparison of the information-giving and information-seeking behaviour of the discussants and also looks at the extent and the content of CoO statements made. Online observation of discussion postings from six different discussion boards (three each from the US and China) was conducted over two 90-day period in 2004 and 2005 and a total of 5,993 discussion postings were downloaded for analysis. In addition, an online survey of 214 participants was conducted to compare the stated and actual (or "revealed") behaviour of discussants on the US and China based discussion boards. -- Overall, the findings indicate consistent differences over a 12-month period in the bahaviour of the US and Chinese discussants. The US discussants were found to provide more information than their Chinese counterparts while the Chinese discussants exhibited more information-seeking bahaviour on the discussion boards. The findings also indicate that the Chinese discussants demonstrated more negative CoO statements and these statements were observed to be related to Japan and/or brands that originated from Japan. The findings suggest that such negative CoO statements can increase rapidly online and it appears that the negative sentiments by the Chinese were apparently unrelated to product quality; instead they appear to have been predominantly associated with war related animosity. -- These findings have important implications for marketers selling to the Chinese as discussion boards appear to be more important as a source of information for the Chinese than the Americans. Also, given that the Chinese discussants demonstrated a high level of negative CoO statements relating to products from Japan, marketers selling Japanese products to the Chinese must understand the underlying issues related to these negativeCoO statements and take steps to prevent non-purchase of Japanese products.

Dès lors que les utilisateurs ont plusieurs centres d'intérêts, ils sont décrits par des profils, un profil correspondant à un centre d'intérêt particulier. C'est la partie structurée du système.
Pour construire une description des profils, les utilisateurs jugent des documents en fonction de leur intérêt
Le système regroupe les profils similaires pour former un certain nombre de communautés virtuelles
Une fois les communautés virtuelles définies, des documents jugés comme intéressants par certains utilisateurs d'une communauté peuvent être partagés dans toute la communauté. C'est la partie collaborative du système.
Le système a été validé sur plusieurs corpora de documents en utilisant une méthodologie précise et offre des résultats prometteurs.

The main purpose of this project is to build a bank system that offers a friendly and simple interface to let users easily manage their lightweight currencies. The Lightweight Currency Protocol (LCP) was originally proposed to solve the problem of fairness in resource cooperatives. However, there are other possible applications of the protocol, including the control of spam and as a general purpose medium of exchange for low value transactions. This project investigates the implementation issues of the LCP, and also investigates LCP bank services to provide human interface to currency operations.

Full textAbstract:
As empresas de manufatura necessitam integrar seus processos internos digitalmente para se tornarem mais competitivas e entregarem produtos com maior qualidade ao mercado consumidor. Informações definidas nas primeiras etapas de projeto precisam ser recuperadas em todas as fases do ciclo de vida de um produto. Para alcançar este objetivo são necessários modelos de informação que incorporem inteligência e permitam a representação do mundo real. Por outro lado, fabricantes de produtos eletroeletrônicos precisam cumprir requisitos ambientais presentes em marcos regulatórios, como a Diretiva RoHS, para poderem vender seus equipamentos em diversos países. O presente trabalho propõe a aplicação de modelos semânticos para ajudar as empresas a cumprir os requisitos estabelecidos pela Diretiva RoHS. O modelo, criado usando uma ontologia de referência, estabelece relações semânticas entre entidades que representam fases do ciclo de vida do produto, estruturas de produtos e objetos de negócios. Processos de negócio modelados permitem identificar fluxos de informação, bem como atividades que estão ligadas aos requisitos RoHS, percebidas por meio da geração de relatórios disponíveis no framework denominado Projeto Essential. O modelo semântico resultante é, portanto, útil para converter as necessidades relacionadas com o meio ambiente, endereçando requisitos através de um processo de desenvolvimento de produtos que aborda a diretiva RoHS. Um produto eletroeletrônico fabricado por indústrias nacionais foi selecionado para demonstrar a viabilidade da solução proposta.Manufacturing companies need to integrate their internal processes digitally to become more competitive and deliver higher quality products to the consumer market. Information defined at early design stages needs to be recovered at all stages of the life cycle of a product. To accomplish this, information models that incorporate intelligence and enable the representation of the real world are necessary. On the other hand, electronic products manufacturers need to comply with environmental requirements present in regulatory frameworks as the RoHS Directive in order to offer their products in several countries. The present work proposes the application of semantic models for helping companies meet the requirements established by the RoHS Directive. A model, created using a reference ontology, establishes semantic relationships between entities that represent product lifecycle stages, product structure and business objects. Business processes, modeled in the form of activity and information flows, are linked to RoHS requirements that can be viewed through the reports in the Essential Project open source framework. The resulting semantic model is, therefore, useful for converting environment-related needs to design requirements through a product development process that addresses the RoHS Directive. A consumer electronics product has been selected for demonstrating the feasibility of the proposed solution.

Full textAbstract:
The use of cellphones has increased all over the world. That invites many academics to conduct research on the usage of these devices, especially by young people, since young people join Social Network Sites (Facebook, Mxit, 2go, Whatsapp) and use a shorthand language. Most studies are related to the use of English and other languages that are recognised by computer software. There are few studies, if any, that have been done in relation to the use of African Languages on these sites. This research therefore aims to seek to explore the use of African Languages, especially isiXhosa, in assessing how technology might help in language development through the usage of SNSs that learners already use to equip them with educational material in their mother tongue. This study was conducted in two high schools, Nogemane Senior Secondary School in a disadvantaged and remote rural community with limited access to additional educational material such as magazines, newspapers, and television. The school also lacks basic study materials such as textbooks from the Education Department and they have no access to a library and laboratory. They also only have very few subjects to choose from. Nombulelo Senior Secondary School is in Grahamstown. This school has good infrastructure and learners have access to different technological devices and they can access libraries. What is common between learners in both schools is that they are all doing isiXhosa as a first language and are using SNSs to interact with each other. This study has found that learners enjoy using SNSs rather than reading the printed books. Furthermore, they enjoy and prefer interacting in isiXhosa in their conversations. Learners also use the web to post and show their creative writing, regardless of the shorthand form writing they use on the SNSs. This study has found that learners are not well equipped with basic isiXhosa skills when reaching the FET phase. They lack the understanding of standard isiXhosa idioms and proverbs. That clearly means that they are equipped in the more modern forms of literature rather than the traditional oral forms. IsiXhosa teachers also see SNSs as the better platform to engage with learners and they suggest that there must be a section in the subjects at school that teaches about cyber bullying and being safe online. This thesis also presents examples of new and contemporary forms of SNS-speak that are used by learners in both the rural and urban schools. This study is more concerned with SNSs for literacy development and to assess whether the shorthand writing has negative or positive effects in writing isiXhosa. This is done against the backdrop of a literature review which explores new literacies, computer mediated communication, social identity models as well as language policy and planning.

M.Inf.As more publishers become involved in electronic publishing, information centres need to respond to the challenges of accommodating electronic journals in their collections, as electronic journals are becoming increasingly important to research. In this research the role of the electronic journal within the scholarly communication process is examined. The role played by information providers and information centres in facilitating access to particular content in electronic journals is also studied. Partnerships that are developing between publishers, secondary publishers and information centres are traced. The importance of the publisher in quality control is emphasized. The peer review process is identified as fundamental to the scholarly communication process. The research methods employed were to carry out a literature study and to examine methods of access to electronic journals on the WWW. The Websites of publishers, secondary publishers and information centres were examined, in order to discover how they simplify access to electronic journal content for end-users. A workflow model was devised to serve as a guideline in assisting information specialists in their management of e-journals. The important challenge facing the information specialist is to provide a value added electronic journal service. This can be achieved through producing indexes and abstracts and providing an evaluation of the different sources

Full textAbstract:
The extensive development of change management has offered organizations appropriate strategies, effective approaches and useful concepts to realise the anticipated change. The latest change manifestation that is being given major attention by public organizations is Electronic Government, which is realised through the expansion of Information Technology and the evolution of the Internet.This research has found that the Electronic Government initiative has affected organisational change, particularly in the areas of Strategy, Structure and People. As a result, the performance of the organization has also improved. Therefore, the Electronic Government initiative has had an impact on organisational performance. The results of this research show that Electronic Government intervenes in and affects these three variables independently or/and collectively. Any change in one variable will influence the others and this change can take place in two ways. A model framework is proposed to illustrate this interdependency of all three variables of Strategy, Structure and People within an organization, and the intervention of Electronic Government. The new theoretical framework could contribute to the overall understanding of the intervention of Electronic Government in the organisational change process and its impact on organizational performance.

Power Line Communications (PLC) is a recent and rapidly evolving technology, aiming
at the utilization of the electricity power lines for the transmission of data. PLC
technology opens up new opportunities for the mass provision of local, last-mile access at
a reasonable cost. PLC can furthermore provide a multitude of new Information Society
services - both in the energy and telecom domains - to residential and commercial users
that are difficult or costly to implement through other technologies.
PLC technology has a number of important strengths: it offers a permanent on-line
connection as well as symmetric, two-way communication; it has good performance, very
good geographical coverage, and is relatively cheap because most of the infrastructure is
already in place. Currently, the main weaknesses of PLC technology are that it is still in
the developmental stage.
It is likely not to be the only one: rather, it will be part of a range of complementary
technologies, because each technology yields a different compromise between
bandwidth, reach, noise immunity, and cost. This report starts by looking at access
technologies and describing the power line as a communication medium and then
frequency response and noise characteristics. A transmission technique (OFDM) that
avoids power line noise and uses the common modulation formats is also explained.
The results of this work shows that the power line technology can be used as a
communication channel for urban areas and fast developing rural areas. This is because
of the bandwidth is uses. A proposed future research for slow developing rural areas is
found in the conclusion.Thesis (M.Sc.Eng.)- University of KwaZulu-Natal, 2005.

Full textAbstract:
This dissertation addresses the convergence of ethics, labor, aesthetics, cultural citizenship, and the circulation of knowledge among experimental electronic instrument builders in New York City and Berlin. This loosely connected group of musician-inventors engages in what I call “DIY music technology” due to their shared do-it-yourself ethos and their use of emerging and repurposed technologies, which allow for new understandings of musical invention. My ethnography follows a constellation of self-described hackers, “makers,” sound and noise artists, circuit benders, avant-garde/experimental musicians, and underground rock bands through these two cities, exploring how they push the limits of what “music” and “instruments” can encompass, while forming local, transnational, and virtual networks based on shared interests in electronics tinkering and independent sound production. This fieldwork is supplemented with inquiries into the construction of “DIY” as a category of invention, labor, and citizenship, through which I trace the term’s creative and commercial tensions from the emergence of hobbyism as a form of productive leisure to the prevailing discourse of punk rock to its adoption by the recent Maker Movement.
I argue that the cultivation of the self as a “productive” cultural citizen—which I liken to a state of “permanent prototyping”—is central to my interlocutors’ activities, through which sound, self, and instrument are continually remade. I build upon the idea of “technoaesthetics” (Masco 2006) to connect the inner workings of musical machines with the personal transformations of DIY music technologists as inventors fuse their aural imaginaries with industrial, biological, environmental, and sometimes even magical imagery. Integral to these personal transformations is a challenge to corporate approaches to musical instrument making and selling, though this stance is often strained when commercial success is achieved. Synthesizing interdisciplinary perspectives from ethno/musicology, anthropology, and science and technology studies, I demonstrate that DIY music technologists forge a distinctive sense of self and citizenship that critiques, yet remains a cornerstone of, artistic production and experience in a post-digital “Maker Age.”

The study focused on an exploration of utilisation of Mathematics skills by Technology Education pre-service teachers to enhance conceptual understanding of Electronic Systems during the design and construction of artefacts. This study attempted to discover Mathematics concepts that pre-service teachers utilised in the completion of their artefacts and it encapsulated design and making of a model of a house and an electronics circuit.
Data were collected through qualitative participant observation, semi-structured interviews and the submission of working artefacts. A sample considered for this study was the whole cohort in the EDTE 210 Electronic Systems course at the University of KwaZulu-Natal. Data were collected through observation of construction of a model house and design of a circuit for Electronic Systems in different phases. In each phase of design, observations and notes were supplemented by semi-structured interview questions as design and construction unfolded. Observation looked for the geometry involved in design of a model house and algebra involved in the design of electronic circuits. Data from interviews with the pre-service teachers indicated mathematical connotations in both the modelling of the house and electronics circuits. It was imperative to know how and why certain measurements, angles and shapes were used for their model houses. Furthermore, it was essential to understand the motives behind particular manipulation of different formulas, conversions and fraction implications by pre-service teachers in their design of effective circuit diagrams.
Pre-service teachers at a university level have arithmetic experience which can be used in Technology and may be extended to mainstream Mathematics. It was observed that design and making of this project exposed concepts of Mathematics that made Electronic Systems manageable and comprehensible. Use of projects was discovered to have a positive impact on enhancing understanding of abstract concepts in Mathematics that are essential for Electronic Systems. It is believed that these skills of integrating different areas of learning through interdisciplinarity are paramount for pre-service teachers, as they will soon assume autonomous professional positions for curriculum design in Technology. This provides a diverse approach to conceptual understanding of Electronic Systems through participative learning. Findings and recommendations for effective teaching of Electronic Systems through mathematical skills/concepts are outlined.Thesis (M.Ed.)-University of KwaZulu-Natal, Durban, 2012.
