Barnardt, Gerard Louis. "Electronic communication in the workplace : employer vs employee legal rights." Thesis, Stellenbosch : Stellenbosch University, 2004. http://hdl.handle.net/10019.1/49942.
Full textENGLISH 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 textNew 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 textThis 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.

Full textThe 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 textENGLISH 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.

Full textIn 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.

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.

Full textThe 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.

Full textENGLISH 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.

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.

Full textThis research deals with the use of a participatory design methodology to develop a repository of open educational resources, the Arcaz. Discusses key aspects of neutrality and determinism of technology within the context of Social Studies of Science and Technology and presents some concepts of critical theory of technology related to the democratic construction of technological artifacts. Discusses the philosophical heritage of the movements that led to the emergence of free software, open education and open educational resources and argues that participatory design share similar ideals. It presents concepts of human-computer interaction, interaction design and user centered design, important to enhance the user experience in information systems. It addresses the participatory design as a methodology that allows the democratic participation of users in the technological construction, promoting mutual learning and active voice for the participants. Develops a participatory design methodology adapted to the Arcaz context of use and provides the procedures for the meetings conducted to apply participatory design techniques to the repository and the results obtained. It concludes with a study of some of the interventions suggested in the system and orientations for future applications of participatory practices in the development of the repository and a list of best practices, focusing on ethical principles that should guide the participatory design.

Full textAujourd'hui, la gestion des documents est l'un des problèmes les plus importants en informatique. L'objectif de cette thèse est de proposer un système de gestion documentaire basé sur une approche appelée recherche structurée et collaborative. Les caractéristiques essentielles sont :
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.

Full textManufacturing 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 textAs 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 textThis 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.
