Internet-regulering in Suid-Afrika : staat of internasionaal?

Amoraal, Lezel 04 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The Internet has become such an integral part of computer users' daily existence that it seems as if it has always been there. The Internet with its unique borders - or lack of borders - places an enormous burden on geographically based legal systems. Regulation, that has specifically been designed for the Internet, is a necessity because virtually every aspect of the law is challenged by the Internet and that many legal frameworks are inadequate to deal with the Internet. The other aspect which complicates the Internet even more, is that there is no specific organisation, business or government to whom the Internet belongs. Individuals and organisations have rights to the web pages that they own on the Internet, but there is no ownership of the Internet in its entirety. The development of the Internet in South Africa took place during a difficult time in the country's history. The apartheid era initially limited the growth of the Internet. Much of the existing legislation in South Africa has been partially adapted to accommodate the Internet, but the government could not envisage what the actual impact of the Internet would be and consequently they reacted when it came to the regulation of the Internet. In 2002 the Electronic Communication and Transaction Act 25 of2002 came into operation. In fact, the physical component of the Internet has already been regulated to a degree by the pure coincidence as a result of its physical presence. This is because the backbone of the Internet had not originally been created by the Internet, but by the telephone. There are a number of legislative Internet-organisations that are, among others, responsible for the technical standards of the Internet, dispute resolutions and in general what is important for the Internet community. Various international conventions regulate specific aspects of the Internet such as copyright, intellectual property rights, domain names, trademarks and cyber crime. The international conventions and agreements are an important step in the direction of standardised regulation. However, the lack of borders creates problems surrounding jurisdiction of the cyber space. / AFRIKAANSE OPSOMMING: Die Internet het al so deel van rekenaargebruikers se alledaagse bestaan geword dat dit soms wil voorkom asof dit maar nog altyd daar was. Die Internet met sy unieke grense - of sy gebrek aan grense - plaas 'n groot las op geografies gebaseerde regstelsels. Regulering wat spesifiek vir die Internet ontwerp is, is 'n noodsaaklikheid, aangesien byna elke aspek van die reg deur die Internet uitgedaag word en baie regsraamwerke onvoldoende is om die Internet te hanteer. Wat die regulering van die Internet verder kompliseer, is dat daar nie een spesifieke organisasie, onderneming of regering is aan wie die Internet behoort nie. Individue en organisasies het regte tot die webwerwe wat hulle op die Internet besit, maar daar is nie eienaarskap van die Internet in sy geheel nie. Die ontwikkeling van die Internet in Suid-Afirka het tydens 'n moeilike tydperk in die Suid- Afrikaanse geskiedenis plaasgevind. Die apartheidsera het die aanvanklike ontwikkeling en groei van die Internet in Suid-Afrika beperk. Verskeie bestaande Suid-Afrikaanse wetgewing is deels aangepas om die Internet te akkommodeer, maar die regering het nooit besef wat die werklike impak van die Internet sou wees nie en het gevolglik re-aktief te werk gegaan wanneer dit by die regulering van die Internet gekom het. In 2002 het Suid-Afrika se Elektroniese Kommunikasie en Transaksies Wet 25 van 2002 in werking getree. Die regulering van die fisieke komponente van die Internet is tot 'n mate as gevolg van sy fisieke teenwoordigheid deur blote toeval, gereguleer. Dit is omdat die ruggraat van die Internet nie oorspronklik vir die Internet geskep is nie, maar vir die telefoon. Daar bestaan verskeie wetgewende Internet-organisasies wat onder meer verantwoordelik is vir die tegniese standaarde van die Internet, dispuutresolusie en wat oor die algemeen aan die belange van die Internet-gemeenskap wil voldoen. Verskeie internasionale konvensies reguleer spesifieke aspekte van die Internet soos kopiereg, intellektuele eiendomsreg, domeinname en handelsmerke en kubermisdaad. Die internasionale konvensies en verdrae is 'n belangrike stap in die rigting van gestandaardiseerde regulering. Tog skep die grenslose omstandighede van die Internet probleme rondom jurisdiksie in die kuberruim.

Community@cyberspace.com : an ethnography of community and commerce on the Internet

Conradie, Liesl 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: The Internet and its Cyberspaces were developed in the 1960s to create a means to transfer information without the risk of interception and annihilation. Today, 40 years later, the Internet has grown in both size and application. The most used applications are still conversation and sharing of information. This thesis is an ethnographic account of my experiences in a Cyberspace of the Internet- a virtual community with the name Amazon City.com. Virtual communities are spaces on the Internet where people come together to discuss their daily lives, issues and anything that's appropriate for the particular community. It is seen as a response to the demise of third places in off-line life, globalisation, etc. The communities that form in these areas develop cultural assumptions. These cultural assumptions are revealed to a new member through time and interaction in the conferencing area. The assumptions that I experienced range from knowledge needed to be an excepted and successful member of the community, to language use and identity of the members. The conclusion was reached that members view their participation and membership in these communities as just as fulfilling and real as their activities in off-line communities. Further aspects that make a site a growing and economically feasible business strategy for its owner(s) were my next focus. Internet commerce is growing at an astonishing rate. Internet business does not only imply the selling of products on-line. Computermediated communication devices have been implemented on commercial sites after it was found in the early 1990s that people are looking for something more than just another shopping area. Other ways that this type of dot com site uses to generate revenue and whether the members on the site are perceived as citizens or ultimately as consumers were also studied. It was found that members see themselves as citizens but site loyalty will push them to act as consumers when need be. The commercial aspects of these sites are a part of and necessary for the existence of the dot com site, and the community that fosters there. / AFRIKAANSE OPSOMMING: Die Internet en sy Kuberruimtes is ontwikkel in die 1960s as 'n manier om inligting oor te dra sonder die risiko van intersepsie en vernietiging. Vandag, 40 jaar later het die Internet gegroei in beide grootte en toepassing. Die mees algemene gebruike is nogsteeds kommunikasie en die oordrag van inforrnasie. Hierdie tesis is 'n etnografiese studie van my ervaringe in 'n Kuberruimte van die Internet- 'n virtuele gemeenskap byname Amazon City.com. Virtuele gemeenskappe is areas op die Internet waar mense bymekaar kom om hul daaglikse lewens, kwessies en enige iets toepaslik vir die spesifieke gemeenskap, te bespreek. Die tipe gemeenskap word gesien as 'n reaksie van die verval van "derde plekke" in af-lyn lewe en globalisering Die gemeenskap wat vorrn in hierdie areas ontwikkel kulturele veronderstelling. Hierdie veronderstellings word openbaar aan 'n nuwe lid deur tyd en interaksie in die konferensie area. Die veronderstellings wat ek ervaar het strek van kennis benodig am 'n aanvaarde en suksesvolle lid van die gemeenskap te word, tot taal gebruik en identiteit van die lede. Die konklusie is bereik dat lede hul interaksie en lidmaatskap in hierdie gemenskappe as net so bevredigend en "eg" ervaar as hul aktiwiteite in hul af-lyn lewe . Verdere aspekte wat 'n webblad 'n suksesvolle en ekonomiese vatbare besigheids strategie maak vir sy eienaar, was my volgende fokus. Internet besigheid groei teen 'n geweldige spoed, en impliseer nie slegs die verkoop van produkte aanlyn nie. Rekenaar-ondersteunde komrnunikasie toestelle is geimplimenteer op kornmersiele webbladsye nadat dit gevind is in die vroee 1990s dat mense soek vir 'n plek wat meer is as net nog 'n winkel. Ander maniere wat hierde dot com webbladsye gebruik am inkomste te genereer en of die lede gesien word as burgers of as verbruikers word ook bestudeer. Daar is gevind dat die lede hulself sien as burgers maar webbladsy lojaliteit sal die lede aanspoor om as verbruikers op te tree indien nodig. Die kommersiele aspekte van die tipe webbladsy is 'n noodsaaklik deel vir die voortbestaan van die dot com webbladsy, en die gemeenskap wat daar ontwikkel.

Congo-Nigeria hydroelectric superhighway grid : an economic viable option / Anieheobi Callistus C.

Anieheobi, Callistus Chukwuemeka January 2008 (has links)
Electricity availability and stability have a great contributory share of industrialization growth rate, poverty statistics, unemployment, foreign investors' participation, medium and small scale encouragement, crime and mortality rates recorded in any country. Nigeria as a country has been challenged with unstable and unreliable power supply. There are many problems associated with electricity production in Nigeria. Such problems are recorded in the generation, transmission and distribution facets of electricity production. With a multi-faceted problem, this document has been developed to deal with the economic aspect of power generation in Nigeria. Out of numerous technologies that are used in power generation, Nigerian predominantly sources its electricity supply from gas power plants and hydropower systems located within the country. Unfortunately, the Nigeria hydropower has been challenged with hydrological shortfalls. The gas power plant which is now conventional is being challenged with the developing gas technology around the globe. This development has adversely affected the cost of gas and subsequently the cost of power production using gas power plants. As a result of hydrological limitations on Nigerian hydropower dams, effect of gas price on cost of energy produced and diversifying gas technology, harnessing electric energy from Inga falls of River Congo was considered as an economic choice of power production in Nigeria. The choice of power production adopted in this document was made from an economic viability studies carried out between Nigerian gas power plants and hydropower production from the River Congo. The choice of technology employed for harnessing electric energy is largely dependent on the economic factors that go with the development. While some of these technologies go with large initial capital investment some are challenged with geometric increase of running cost. As applied in this work, the Net Present Value, Internal Rate of Return, Levelized Cost of Energy and Cash Flow Trend Analysis are suitable tools to determine choice of power plant. These tools were integrated and developed as an NILC model. In the analysis presented in this dissertation, the economic viability of the two power plants selected was determined with the use of the Net Present Value, Internal Rate of Return, Levelized Cost of Energy and Cash Flow Trend Analysis (NILC) model. The model was used to measure the economic viability quantities of the two power plants selected for economic comparison. After the completion of economic comparative analysis, hydropower production from the River Congo was concluded to be a better choice of power production compared to the conventional gas power plant option in Nigeria. / Thesis (M.Ing.

Information and knowledge management in support of legal research in a digital information environment

Du Plessis, Tanya 08 January 2009 (has links)
D. Litt. et Phil. / The main research question addressed by this study is whether the application of information and communication technologies (ICTs) has an effect on the practice of law, and specifically whether information and knowledge management affects the process of legal research. Various issues are considered in this regard, including what the concept of knowledge management (KM) entails in a law firm and what the current KM trends are in South African law firms. To this extent an investigation follows of the global trends in the application of ICTs for legal research purposes and what the specific applications are of KM in support of legal research. Furthermore, this study investigates how information technology applications and KM systems and strategies can support the legal research process and what the benefits of KM are to legal research. This entails a study of the unique characteristics of legal research in a digital information environment and of the challenges legal researchers face in a changing information environment. Subsequently the skills and tools that are required for effective digital legal research are discussed. This research also considers the effect the changing information environment has on the role of the legal information professional, which includes an investigation of the reasons why legal information professionals can and should support lawyers in their legal research activities. Specifically, this study considers the roles, skills and competencies of legal information professionals as knowledge managers, digital librarians and trainers of legal research skills in a changing information environment. Lastly, this study investigates whether current legal research skills training offers useful guidelines to future digital legal researchers.

An exploration of creative thinking skills in the grade 9 technology classroom

Nkosi, Praygod Bonginkosi January 2020 (has links)
Thesis (M.Ed. (Mathematics, Science and Technology Education)) -- University of Limpopo, 2020 / The purpose of this is to investigate how teachers go about for the development of Creative Thinking Skills (CTS) in a grade 9 technology classroom. The introduction of technology in the South African curriculum by the Department of Basic Education (DBE) to develop CTS through the Design Process (DP) as the cornerstone of the learning area. Technology as a learning area should provide learners with opportunities to solve real-life problems, in the process developing their CTS (DBE, 2011). In the 21st century, CTS have been seen as skills that are crucial across the spectrum of day to day activities. However; it appears to be very complex for technology teachers to enhance the teaching and learning of CTS in a technology classroom. The literature suggests that technology teachers tend to suppress the development of learners’ CTS by limiting the process of teaching and learning to low order thinking cognitive levels rather than high order cognitive levels. This study employed a qualitative research enquiry, purposive sampling was used for the selection of the relevant participants. Qualified technology teachers who teach grade 9 technology with at least three years’ experience in teaching technology were considered. Data collection was obtained through interviews, observation and document analysis. The research finding showed that teachers lack the understanding of policies, particularly CAPS hence they continuously compromise its implementation hindering with the development of CTS of learners as it is envisaged in the CAPS document. Furthermore, the research findings reveal that the teacher has a little or no understanding of what is creative thinking (CT) and what it entails, hence they did not unpack what is it exactly that they do to support the development of learners CTS in a technology classroom This study recommends that technology teachers be familiar with the CAPS document and implement it correctly without any compromise. Furthermore; understanding of the design process is of vital importance to teachers as it is the cornerstone of teaching and learning, particularly the development of CTS of learners. Technology teachers need also to have a clear understanding of what CT is and what it entails, that will assist to arouse their CT and help to develop the CTS of learners in a technology classroom.

La société de l'information déstabilise-t-elle l'Etat-Nation ?analyse comparative du développement des nouvelles technologies de l'information et de la communication dans l'âge de la mondialisation

Arena, Gianmatteo 28 October 2004 (has links)
La société de l’information déstabilise-t-elle l’Etat-Nation ?<p>Analyse comparative du développement des nouvelles technologies de l’information et de la communication dans l’âge de la mondialisation<p><p>Partant du constat que le concept “Société de l’Information” est souvent utilisé dans des contextes et des situations très différents, qui ne présentent guère de traits communs, ce travail abouti à une interprétation de ce concept, qui permette de la redimensionner au lieu d’en faire un mythe, comme cela arrive trop souvent. La “Société de l’Information”, malgré son rôle innovant et unificateur qui outrepasse même les barrières étatiques, est confrontée au poids de l’Etat-Nation dans sa conception la plus restrictive. <p>Nous considérons cette analyse comme une réflexion nécessaire dans une période où le défi technologique est particulièrement chargé d’un rôle politique. / Doctorat en sciences politiques / info:eu-repo/semantics/nonPublished

Globalisation, communication et champ du pouvoir. Une socio-économie comparée des structures actionnariales et dirigeantes des groupes de médias et des entreprises dans le domaine des Nouvelles Technologies de l'Information et de la Communication en Europe et aux États-Unis

Geuens, Geoffrey 22 May 2007 (has links)
Les « Nouvelles Technologies de lInformation et de la Communication » (NTIC) font aujourdhui lobjet dune abondante littérature, tant francophone quanglo-saxonne. Lobjectif de la thèse était précisément de soumettre à lanalyse critique cette prolifération de discours le plus souvent clichés associés, pour les uns, à la « société de linformation », pour les autres, à la « mondialisation » de léconomie qui forment presque un discours social à part entière, et dont lun des traits communs est notamment de révoquer en doute, à lexemple des phénomènes examinés sous le point de vue quils adoptent, les principaux référents théoriques dantan. Les « idéologèmes » véhiculés par ce discours social, on la montré, relèvent pour lessentiel de trois grandes catégories particulièrement saillantes, organisées en loccurrence sous la forme de trois binômes largement reçus, qui tendent à fonctionner comme des structures de pensée communes : a)Privatisation/désétatisation. La croyance en lomnipotence des communications de masse a généralement son corollaire dans la mise à mort symbolique de lÉtat. Nés de lautorité publique mais arrivés à maturité, les « nouveaux médias » et les NTIC libéralisés auraient enfin acquis leur autonomie et placeraient nos sociétés à lenseigne du réticulaire marchand. La « nouvelle économie » en réseaux se serait définitivement libérée de la tutelle politique, pour le meilleur (dynamisme, efficacité, compétitivité) comme pour le pire (marchandisation, affaiblissement de lÉtat, soumission du politique), selon le point de vue adopté à légard de ces évolutions données pour inévitables ; b)Mondialisation/déterritorialisation. Linternationalisation des structures de pouvoir des groupes de communication entretient une relation organique avec la dépolitisation du secteur. Cest que lexplication majeure de la disjonction État/médias réside, justement, dans la logique de dissociation croissante entre lespace démocratique national et les réseaux technologiques mondiaux. Les nouveaux conglomérats de linformation sidentifieraient alors à des géants transnationaux apatrides et déterritorialisés. Quant à la « financiarisation » des industries culturelles, elle annoncerait la fin des actionnaires de références nationaux et lavènement parallèle dune nouvelle économie sappuyant sur une multitude de petits porteurs disséminés aux quatre coins de la planète dont les investisseurs institutionnels constituent, en quelque sorte, le modèle le plus abouti ; c)Libéralisation/dérégulation. La « dépolitisation » et la « globalisation » des industries technologiques auraient instauré un marché débarrassé des entraves et des privilèges associés aux anciens opérateurs publics. Décidées au nom du libéralisme économique, les réformes de dérégulation adoptées dès le début des années 80 auraient ainsi abouti à la décomposition des antiques monopoles et à la mise en concurrence dentités industrielles isolées les unes des autres. Quant aux conquérants de la Silicon Valley, Media Moguls et autres Tycoons, ils seraient en quelque sorte les effigies suprêmement individuelles de cette métamorphose du « capitalisme numérique » : autant de managers déracinés, dépeints comme dinfatigables compétiteurs apolitiques, engagés dans une course féroce au gigantisme, nayant pas la moindre solidarité de classe et nayant pour seul moteur que la quête du profit à court terme. Les discours convenus touchant à la « société de linformation » et aux phénomènes de « globalisation », il nous faut en réalité les relativiser, sinon même les infirmer, à la lumière de nos observations et analyses. Cest que la « mondialisation » de léconomie doit en effet compter non seulement avec la permanence de particularismes nationaux dont témoignent les structures de détention et de contrôle des groupes de médias et des NTIC, mais également avec le fait que la très grande majorité des entreprises étudiées sont caractérisées par un rapport entre investisseurs résidents et non-résidents tournant très nettement à lavantage des premiers. On peut ainsi affirmer que les « multinationales » de la communication nexistent pas. Souhaitée par les uns ou redoutée par les autres, mais proclamée par tous, la « financiarisation » des industries culturelles na pas, en effet, débouché sur la trans-nationalisation du capital dont elle se voulait, pourtant, annonciatrice. Le « marché global » de linformation demeure, à ce jour, une vue de lesprit séduisante, mais scientifiquement non fondée, les réseaux technologiques nayant pu transformer les capitalismes en un marché mondial faisant fi des principaux référentiels dantan tels que ceux de « propriété », de « classes sociales » et de « souveraineté nationale ». Quant au pouvoir des grands actionnaires traditionnels (familles, pouvoirs publics, etc.), il na pas non plus cédé face à la pression des fonds dinvestissements anglo-saxons, mais sest au contraire consolidé à cette haute finance ayant permis le lancement dopérations de fusion et acquisition, sans précédent jusque-là, dans le secteur de la communication. La « globalisation » des réseaux informationnels ne sidentifie pas, enfin, à la régénérescence dun libéralisme pur et parfaitement concurrentiel, mais à la réaffirmation de quelques-unes des caractéristiques les plus fondamentales des industries culturelles en régime capitaliste : concentration de la propriété des firmes, centralisation de léconomie nationale, fusion des intérêts bancaires et industriels, consolidation des principaux holdings et, enfin, imbrication des groupes financiers et de lappareil dEtat. On aurait tort cependant de se limiter à une approche strictement financière de ces phénomènes. La situation quasi monopolistique que connaissent certaines compagnies leaders dans le domaine de la presse ou des NTIC ne séclaire, en effet, véritablement quà la lumière de leur très forte centralité au sein des réseaux de pouvoir. La densité des relations que les firmes en question entretiennent avec lappareil dEtat, les principales entreprises industrielles et financières, et les plus influents groupes de pression et autres think tanks constitue à nos yeux la première des conditions garantissant la reproduction des positions dominantes occupées par ces sociétés privées sur leur marché respectif. Cette approche relationnelle du pouvoir économique est illustrée par la multiplicité des positions institutionnelles détenues par les dirigeants des entreprises médiatiques. Représentant autant de formes incarnées de relations sociales génériques entre Economie, Politique et Communication, les grands administrateurs, issus pour la plupart dentre eux du secteur financier ou de la très haute fonction publique, peuvent être légitimement considérés, pour parler le langage un peu oublié dun Gramsci, comme les intellectuels organiques de la fraction hégémonique du bloc au pouvoir. Ce quil faut, au total, rejeter dans la définition des médias en tant que « quatrième pouvoir » ou dans celle des réseaux numériques en tant que « nouveaux pouvoirs », cest limpensé théorique qui sous-tend cette représentation dune industrie de la communication qui « globalisée », « libéralisée » et « dérégulée », se serait simultanément affranchie des territoires nationaux, des gouvernements et de la grande bourgeoisie daffaires. Il nest pas non plus conforme à la vérité des faits et de leur recoupement de penser que la classe dirigeante ne se servirait de la presse que comme vulgaire relais ou instrument de propagande. Tout semble plutôt se passer comme si le champ du pouvoir était invaginé dans le champ médiatique du fait de la circulation ininterrompue de certains agents sociaux privilégiés entre les divers sous-espaces constitutifs du champ du pouvoir (pouvoir économique, pouvoir dEtat, pouvoir idéologique, etc.).
