This paper was designed to mitigate this problem for Nigeria and countries with similar dispositions. Based on a survey involving field trip to Nigeria, the paper examines the general security situation in Nigeria and its mutual impacts with computerisation, miniaturisation and Location-Based Authentication (LBA). It was discovered that both computerisation and miniaturisation had some negative effects on cybersecurity, as these were being exploited by fraudsters, especially using ‘advance fee fraud;’ popularly called 419. As a countermeasure, the research examined the possibility of using LBA and further digitisation of the GSM Mobile country codes down to City/Area codes along with GSM Mobile/Global Positioning System (GPS) authentications. Where necessary, these could be combined with the use of a web-based Secret Sharing Scheme for services with very high security demands. The anticipated challenges were also examined and considered to be of negligible impacts; especially roaming. / Petroleum Technology Development Fund (PTDF) Cyber space Computerisation Miniaturisation Authentication Advance Fee Fraud (419) Digitisation Tele-density

5	Validity, reliability and fairness of item measurements attained by a comprehensive computer-assisted assessment tool van der Merwe, Preller Josefus January 2006 (has links) Thesis (M.Tech. (Information Technology, Faculty of Applied and Computer Sciences))--Vaal University of Technology, 2006 / The sole purpose of a test is to make a measurement. Assessment is very much a process of measurement, whether the outcome is used for baseline, diagnostic, formative or summative purposes. When measurement is taken, in whatever form, a score is obtained. The score that is obtained forms the important part of assessment, because this score determines the outcome of the assessment, the decisions that are to be made regarding the student’s progress, curriculum changes and the evaluation of a course as a whole. Although a score is obtained from a test, the analysis thereof is frequently much neglected. The use of computers in education is not a new concept. The first computer application goes back a long way when computers were first used to do psychological testing. It then became clear that computers can be applied to more fields in education, especially in the field of testing. In the early days real progress was slow, since computers were expensive and were only used in large companies. However, the scenario has changed with the widespread availability of personal computers that has enabled educators to focus on the appropriate role of computerisation in the development, administration, scoring and interpretation of tests. The main objective of this study is to show the major advantage of using computers as a comprehensive assessment tool and to demonstrate the ability to construct and ‘bank’ test items to subsequently produce a standardised test. An added advantage was the computer’s ability to administer tests to students and manage student progress records. The research findings indicate that a Comprehensive Computer-Assisted Assessment Tool (CCAT) has the potential to contribute to the enhancement of assessment and that it can enable educators to prepare valid, reliable and fair test items which were more difficult and time-consuming without technology.

6	Smart, Fast and Beautiful : On Rhetoric of Technology and Computing Discourse in Sweden 1955-1995 Johansson, Magnus January 1997 (has links) Ever since the computer was introduced some 50 years ago, its role in society has been increasing. From being a tool for scientists and technicians, the computer has become a concern for everyone. Different actors engaged in introducing — or denouncing — this technology, have used many strong words for winning others to the cause. The high symbolic value tied to computers and information technology has made the rhetoric used to "sell" these very explicit. This discourse, the language and arguments used, is the object of study in the dissertation. When it became clear that computers could be used also for rationalising administration, the Swedish government started to investigate how this could be done. In the 1960s, this became one of the first big computerisation projects in Sweden. It turned out to be a controversy between two different ways of organising a big administrative system: national contra regional/local or hierarchical contra decentralised. It also turned out to bee a "war" between the suggested computer makes that should equip the County Computer Centres. In the late 70s, when the "PC revolution" was only beginning, the Luxor ABC 80 computer became the best selling micro in Sweden, outscoring TRS-80, Apple II and Commodore PET many times. From 1978 to 1986 Luxor ABC computers were by far the most used personal computers. A decade later, in the early 1990s, the info-highway hype struck Sweden. Giving politicians arguments for a new wave of computerisation, but now less based on technology and more directed towards the use of "information superhighways" which the development within IT had made possible. These three instances in Swedish computing history form the historical background for this study of computer rhetoric, of the discourse that evolves when a new technological frame is being introduced in society. The social construction of artefacts is an outcome of communication between people. Therefore the language used by different actors in the various "texts" they produce is of vital interest if we want to understand technology and our relationship with it. But it is also true that technology helps to set the frames of our minds. A rhetoric of technology must take this relation into account. / The electronic version of the printed dissertation is a corrected version where all spelling and grammatical errors are corrected. rhetoric of technology computing history technological discourse technological frame actor network STS social construction computerisation information technology computer science government policy SOCIAL SCIENCES SAMHÄLLSVETENSKAP
7	Regsaspekte van die rekenarisering van die betalingstelsel Meiring, Gezina Aletta 11 1900 (has links) Text in Afrikaans, abstract in Afrikaans and English / The development of sophisticated computer technology and the consequent computerisation of the payment system has had a far-reaching effect on fund transfer systems all over the world. The most important purpose of this thesis is to indicate the nature of an electronic fund transfer; to set out the relationships of the parties involved in an electronic funds transfer and to show by comparison with other legal systems where our law may be deficient in the regulation of the computerised payment system. At the outset, the nature and functions of money are compared to electronic fund transfers and a distinction drawn between paper-based transactions and electronic fund transfers. In this regard, electronic fund transfers as method of payment is also discussed. Automatic computer processing also gave rise to a variety of new kinds of financial services. A distinction is made between customer-initiated systems (A TM' s, EFTPOS and home-banking services) and systems used by the banks to effect electronic funds transfers between banks and to send financial messages. In this regard, the settlement function of clearing houses and the legal nature thereof are examined. A description of a local clearing house, the ACB, is included as well as a discussion of the clearing of cheques, the moment of payment of cheques and the status of the ACB. Other relevant legal aspects of the computerisation of the payment system which are examined and discussed are the following: the use of the so-called electronic signature; the regulation of risks in electronic payments and the creation of sufficient security measures; the criminal liability of an accused in the case of an unauthorised withdrawal or transfer; questions and problems surrounding evidential matters; the putting into operation of procedures to correct errors and the creation of an ombudsman to settle and resolve disputes; cheque truncation and the right of an individual to privacy in the milieu of electronic payments. Finally, the legal relationships between the parties involved in a credit transfer and the moment of payment is examined. Regulation in this regard is also considered. / Die ontwikkeling van gesofistikeerde rekenaartegnologie en die gevolglike rekenarisering van die betalingstelsel het 'n verreikende effek op die fondsoordragstelsels van banke regoor die wereld gehad.

In die verband is die verrekeningsfunksie van klaringshuise en die regsaard daarvan ondersoek. 'n Beskrywing van die werksaamhede van die ACB, as plaaslike klaringshuis, is hierby ingesluit asook 'n bespreking van die verrekening van tjeks, die tydstip van betaling van tjeks en die status van die ACB.

9	Las nuevas tecnologías en la administración de justicia. La validez y eficacia del documento electrónico en sede procesal Jaume Bennasar, Andrés 09 October 2009 (has links) La tesis se encarga de analizar, por un lado, la integración y el desarrollo de las nuevas tecnologías en la Administración de Justicia; y, por otro, los parámetros que constituyen la validez y eficacia del documento electrónico. La primera cuestión se centra en la configuración de los Sistemas de Información de la Oficina Judicial y del Ministerio Fiscal, así como de la informatización de los Registros Civiles, donde el art. 230 LOPJ es la pieza clave. Se estudian sus programas, aplicaciones, la videoconferencia, los ficheros judiciales y las redes de telecomunicaciones que poseen la cobertura de la firma electrónica reconocida, donde cobran gran relevancia los convenios de colaboración tecnológica. La digitalización de las vistas quizá sea una de las cuestiones con más trascendencia, teniendo en cuenta que el juicio es el acto que culmina el proceso. Aunque no todos los proyectos adoptados en el ámbito de la e.justicia se han desarrollado de forma integral, ni han llegado a la totalidad de los órganos judiciales. El objetivo final es lograr una Justicia más ágil y de calidad, a lo cual aspira el Plan Estratégico de Modernización de la Justicia 2009-2012 aprobado recientemente.En referencia a la segunda perspectiva, no cabe duda que el Ordenamiento jurídico y los tribunales, en el ámbito de la justicia material, otorgan plena validez y eficacia al documento electrónico. Nuestra línea de investigación se justifica porque cada vez son más los procesos que incorporan soportes electrónicos de todo tipo, ya sea al plantearse la acción o posteriormente como medio de prueba (art. 299.2 LEC). Entre otros temas examinamos el documento informático, la problemática que rodea al fax, los sistemas de videograbación y el contrato electrónico. / La tesi s'encarrega d'analitzar, per una part, la integració i el desenvolupament de les noves tecnologies dins l´Administració de Justícia; i, per l'altra, els paràmetres que constitueixen la validesa i l'eficàcia del document electrònic. La primera qüestió es centra en la configuració dels Sistemes d´Informació de l´Oficina Judicial i del Ministeri Fiscal, així com de la informatització dels Registres Civils, on l'art. 230 LOPJ es la peça clau. S'estudien els seus programes, aplicacions, la videoconferència, el fitxers judicials i les xarxes de telecomunicacions que tenen la cobertura de la firma electrònica reconeguda, on cobren gran rellevància els convenis de col·laboració tecnològica. La digitalització de les vistes tal vegada sigui una de les qüestions amb més transcendència, tenint amb compte que el judici es l'acte que culmina el procés. Però no tots el projectes adoptats en l'àmbit de la e.justicia s'han desenvolupat d'una manera integral ni han arribat a la totalitat dels òrgans judicials. L'objectiu final es assolir una Justícia més àgil i de qualitat, al que aspira el Pla Estratègic de Modernització de la Justícia 2009-2012 aprovat recentment. En referència a la segona perspectiva, no hi ha dubte que l´Ordenament jurídic i els tribunals, en l'àmbit de la justícia material, donen plena validesa i eficàcia al document electrònic. La nostra línia d'investigació es justifica perquè cada vegada son més el processos que incorporen suports electrònics de tot tipus, ja sigui quant es planteja l'acció o posteriorment como a medi de prova (art. 299.2 LEC). Entre altres temes examinem el document informàtic, la problemàtica que envolta al fax, els sistemes de videogravació i el contracte electrònic. / The thesis seeks to analyse, on the one hand, the integration and development of the new technologies in the Administration of Justice; and, on the other, the parameters which constitute the validity and efficiency of the electronic document.The first question centres on the configuration of the Information Systems of the Judicial Office and the Public Prosecutor, as well as the computerisation of the Civil Registers, where the art. 230 LOPJ it's the part key. Their programmes, applications, the Video Conferencing, the judicial registers and the telecommunication networks which are covered by the recognised electronic signatures, are studied, where the agreements on technological collaboration gain great relevance. The digitalisation of evidence might perhaps be one of the questions with most consequence, bearing in mind that the judgment is the act by which the process is culminated. Although not all the projects adopted within the compass of e.justice have developed completely nor have reached all the judicial organs. The final objective is to achieve an agile, quality Justice, to which the recently approved Strategic Plan for the Modernisation of Justice aspires.With reference to the second perspective, there is no doubt that the juridical Ordinance and the tribunals within the compass of material justice grant full validity and efficacy to the electronic document. Our line of investigation is justified because there are more and more processes which are sustained by electronic supports of all kinds, whether it be at the establishment of the action or later, as a proof of it (art. 299.2 LEC). Amongst other things, we examine the computerised document, the problems which surround the fax, the systems for video recording and the electronic contract.
