Hoër Onderwys in Suid-Afrika is in 'n proses van transformasie. Hierdie transformasie is onder meer as gevolg van internasionale wereldtendense en die historiese agterstande van onderwys in Suid-Afrika. Dit is derhalwe noodsaaklik dat instellings, soos die Oos-Rand Kampus van die Vaaldriehoekse Technikon, strategiese beplanning in sy bestuursaktiwiteite behoort te inkorporeer. Hierdie studie het strategiese bestuur as sentrale tema met komponente in die Filosofiese Antropologie en in Sakebestuur. In hierdie studie is ondersoek gedoen na strategiese bestuur as dialektiese strategiese bestuur met kenmerke van bi-polere, dualistiese en kontensieuse aard. Dit is vanuit hierdie vertrekpunt dat dialektiese strategiese bestuur in die kategoriee van menswees, soos onder meer synsopenheid, dialoog, toekomstigheid, paties-dinamiese gerelasioneerdheid, verbeelding, selfbewussyn, waardes en vryheid en besluitneming, gefundeer kan word. Dit kan gekonstateer word dat dialektiese strategiese bestuur 'n menslike aktiwiteit is wat in die Filosofiese Antropologie en in die Aksiologie gefundeer is. 'n Ondersoek is ook geloods na faktore wat die toekomstige strategiese posisie van die Oos-Rand Kampus van die Vaaldriehoekse Technikon kan beinvloed en/of bepaal Internasionale en nasionale onderwysfaktore is ondersoek en 'n nie-empiriese opname is onder personeel, studente en werkgewers uitgevoer om inligting te verkry wat in strategiese bestuur gebruik kan word. Die gevolgtrekkings van hierdie studie is in die vorm van strategiese tendense en 'n moontlike bestuursplan uiteengesit wat as 'n vertrekpunt in 'n strategiese plan vir die Oos-Rand Kampus van die Vaaldriehoekse Technikon gebruik kan word. / Higher Education in South Africa is in a process of transfonnation. This transfonnation is, amongst others, due to the international global tendencies and the historic backlog of education in South Africa It is therefore imperative that institutions, such as the East Rand Campus of the Vaal Triangle Technikon, should incorporate strategic planning in its managerial activities. This study has strategic management as a central theme with components in the Philosophical Anthropology and in Business Management. In this study strategic management has been investigated as dialectic strategic management with characteristics of a bi-polar, dualistic and contention nature. It is from this departure that dialectic strategic management can be funded in the categories of being human, namely openness to being, dialogue, futurity, pathic-dynamic relatedness, imagination, self consciousness, values and freedom and decision making. It can thus be stated that dialectic strategic management is a human activity funded in the Philosophical Anthropology and in the Axiology. An investigation has also been done pertaining factors which can influence and/or determine the future strategic position of the East Rand Campus of the Vaal Triangle Technikon. International and national educational factors have been investigated and a non-empirical survey was made among stafl: students and employers as to obtain infonnation that can be used in strategic management. The conclusion of the study is presented in the form of strategic intents and a probable management plan that can be used as a point of departure in a strategic management plan for the East Rand Campus of the Vaal Triangle Technikon. / Educational Studies / D.

Information literacy is a skill and forms the basis for life-long learning. The aim of this study is to investigate the information literacy skills of first year students at the Vaal Triangle Campus of the North-West University (NWU), with specific reference to the role of the academic library. The NWU‟s Vaal Triangle Campus Library supports first-year students in their studies by helping them to improve their information skills and teach them to find, evaluate and organise information in different formats. The purpose of this is to help first-year students to find relevant information that meet their information requirements. Students who are information literate not only have the necessary skills; but also have insight, comprehension, and knowledge at their disposal, while being life-long learners. A compulsory literacy module forms part of the curriculum for first-year students at the NWU‟s Vaal Triangle Campus, and is presented by academic staff. The credit-earning module (known as AGLE 121) consists of three components, namely computer and information literacy, reading literacy, and academic literacy. This study focuses on the module for basic information literacy, which is mainly of a theoretical nature. First year students were tested by questionnaires and interviews before and after completion of the information literacy module, to determine what contribution the module makes to their information literacy. This studyconcluded that after completing the information literacy module, first-year students have the theoretical knowledge at their disposal, but still do not know where to find databases or information. The role of the campus library regarding information literacy is to expand and improve students‟ information skills as well as being involved in the planning and development of the information literacy module. A recommendation is made that the information literacy module should already be offered during the first semester (instead of the second semester), so that students can use their information skills effectively for their studies. / Information Science / M.

Nous étudions la sensibilité de Belle II avec 50 ab-1 de données sur l'angle βc du triangle d'unitarité, avec une mesure en fonction du temps de l'asymétrie de CP dans les désintégrations des mésons D0. Nous montrons que cette mesure est limitée statistiquement, avec une incertitude totale attendue de l'ordre de 3°. La mesure de βc nécessite la reconstruction de trajectoires de particules de très faible impulsion, impactée par le bruit de fond induit par SuperKEKB. Deux échelles PLUME vont être utilisées pour étudier ce bruit de fond. Ici, une étude des performances de PLUME est effectuée. Ainsi, la résolution spatiale avec des traces à 0° et 36° est mesurée, de 1,8 µm et 3,5µm respectivement. Par ailleurs nous proposons d'améliorer la mesure des faibles impulsions en utilisant la charge déposée par la particule dans le trajectomètre interne au silicium. L'estimateur permet d'améliorer par 2% la résolution sur l'impulsion pour les particules n'atteignant pas le trajectomètre interne. / We are studying the sensitivity of Belle II with 50 ab-1 data to the βc angle of the c-u unitarity triangle, with a time-dependent measurement of the CP asymmetry in the D0 decays. We show that such a measurement is still statistically limited, with a total expected incertitude of 3°.This measurement relies on the reconstruction of soft momenta, impacted by the SuperKEKB induced background.Two PLUME ladders will be used to study this background, therefore a study on the performances of PLUME was performed. The spatial resolution is of 1.8 µm and 3.5 µm for 0° and 36° tilted tracks respectivelly.We also propose to improve the estimation of soft momenta using the energy depositions of charged particles in the silicon layers of the inner tracker. Our estimator improves by approximately 2 % the resolution on momentum for particles which do not penetrate the central tracking system.

The shifting focus in the role of academic libraries entail a better understanding, awareness and responsiveness to the needs of the library users. In an environment of change and an age of accountability academic libraries have to determine and demonstrate the impact their resources and services are having on their institutional mission. Service quality is not based exclusively on the perception of the librarians, but also dependent on the perception of users. Only customers judge quality; all other judgments are essentially irrelevant" (Zeithaml, Parasuraman, Berry 1999). The reason of this study was to assess quality in the library and to determine the perceptions of the Vaal Triangle Campus Library users as they relate to quality service and to develop a model to improve service quality. The aim was to determine library users' minimum expectations for services, their desired level of service and then to identify the extent of service they currently perceive on three dimensions of service quality: affect of service, library as place and access to information. A triangulation, mixed method research methodology was employed in this study. Data was collected using focus group as well as individual interviews and the LibQUAL questionnaire. Purposive sampling was used to determine participants for the interviews while a total market survey was employed for the questionnaire respondents. Findings indicate that there is a gap between the users' expectations and perception of service quality. The results indicate that there are variations within the different user groups regarding the expectations and perceptions of service quality at the Vaal Triangle Campus library. In view of the findings, the study concluded by developing a service quality model based on Deming's PDCA cycle, the ISO model and the Hoshin Kanri process / Information Science / M. Inf.

D.Ed. (Educational Psychology) / Since 1989 most of the schools in Lenasia which were under the auspices of the now dissolved House of Delegates, began to 'admit black children. Most of these children live at the informal settlements in Lenasia. Soon after the admission of these children many Indian teachers expressed their difficulties with them, especially with regard to language, teaching and learning. Teachers also complained that children from the informal settlement lacked discipline, they often came to school late and they had difficulty in completing their homework. As a result of the several complaints from teachers the researcher decided to conduct a study on the experiences of children from the informal settlements at predominantly Indian schools in Lenasia. A pilot study revealed that the experiences of the children at the informal settlements also needed to be taken into consideration. Standard six children from the informal settlements, parents from the settlements and members of the camp education committee were identified as the target populations in the study. A qualitative research design that is explorative, descriptive and contextual, specifically to the experiences of standard six children from the informal settlements was used for the study. The study was conducted in two distinct phases. Phase one of the study involved the collection of data on the experiences of standard six children from the informal settlements both at their schools as well as their place of residence. Data was collected through the use of phenomenological interviews, focus group discussions, life studies and a projective test. Phase one of the study also focused on the analysis of the data that were obtained. The analysis of the data showed that children from the informal settlements had several negative experiences both at their schools as well as at the informal settlements which caused them to feel disempowered...

[pt] Subdivisão de superfícies triangulares é um problema importante nas atividades de modelagem e animação. Ao deformar uma superfície a qualidade da triangulação pode ser bastante prejudicada na medida em que triângulos, antes equiláteros, se tornam alongados. Uma solução para este problema consiste em refinar a região deformada. As técnicas de refinamento requerem uma estrutura de dados topológica que seja eficiente em termos de memória e tempo de consulta, além de serem facilmente armazenadas em memória secundária. Esta dissertação propõe um framework baseado na estrutura Corner Table com suporte para subdivisão de malhas triangulares. O framework proposto foi implementado numa biblioteca C mais mais de forma a dar suporte a um conjunto de testes que comprovam a eficiência pretendida. / [en] Subdivision of triangular surfaces is an important problem in modeling and animation activities. Deforming a surface can be greatly affected the quality of the triangulation when as equilateral triangles become elongated. One solution to this problem is to refine the deformed region. Refinement techniques require the support of topological data structure. These structures must be efficient in terms of memory and time. An additional requirement is that these structures must also be easily stored in secondary memory. This dissertation proposes a framework based on the Corner Table data structure with support for subdivision of triangular meshes. The proposed framework was implemented in a C plus plus library. With this library this work presents a set of test results that demonstrate the desired efficiency.

A análise desenvolvida por este trabalho tem como objetivo investigar a produção do espaço na Região do Cariri cearense, através de um fragmento do espaço regional denominado de Triângulo Crato-Juazeiro do Norte-Barbalha. Para realização da investigação, três momentos foram fundamentais. Um primeiro momento consistiu na definição dos fundamentos teóricos e metodológicos visando a definição dos principais conceitos utilizados para compreensão do fenômeno analisado. A abordagem que prioriza a concepção da produção do espaço foi essencial na definição do objeto de estudo e na definição dos fundamentos conceituais. O espaço foi concebido como um fenômeno produzido pela sociedade através do processo de trabalho e ao longo do processo histórico. Além da concepção a respeito do espaço, foram importantes os conceitos e as categorias analíticas como a divisão social e territorial do trabalho, a configuração espacial, as práticas espaciais, as representações do espaço e os espaços da representação. Em um segundo momento, tendo como bases os fundamentos teórico-metodológicos desenvolveu-se uma análise sobre a dinâmica do espaço da Região do Cariri, identificando para cada momento histórico, os agentes responsáveis pela produção do espaço de acordo com cada período. Foi possível dessa forma, propor uma periodização para o processo de produção do espaço regional: a primeira marcada pela ação dos Índios Cariris, uma segunda estruturada a partir da colonização e do comando do município de Crato, uma terceira caracterizada pela ascensão do município de Juazeiro do Norte e uma quarta produzida com base na atual fase do capitalismo e o processo de globalização. Um terceiro momento diz respeito à análise teórica e empírica do processo de produção do espaço Triângulo Crato-Juazeiro do Norte-Barbalha. A análise evidencia a importância do processo de globalização e da atual dinâmica do modo de produção capitalista na estruturação de uma nova configuração espacial para a Região do Cariri. Na produção dessa nova configuração espacial, o Estado, as empresas (nacionais e transnacionais), os bancos e as classes sociais se destacam como agentes que comandam e controlam a organização do espaço. / The analysis developed by this work aims to investigate the production of space in the Cariri region of Ceará, through a fragment of the regional space called the Crato-Juazeiro do Norte-Barbalha triangle. To carry out the research, three moments were fundamental. A first moment consisted in the definition of the theoretical and methodological foundations aiming at the definition of the main concepts used to understand the phenomenon analyzed. The approach that prioritized the design of \"space production\" was essential in defining the object of study and in defining the conceptual foundations. Space was conceived as a phenomenon produced by society through the work process and throughout the historical process. In addition to the conception of space, analytical concepts and categories such as the social and territorial division of labor, spatial configuration, space practices, representations of space, and spaces of representation were important. In a second moment, based on the theoretical-methodological foundations, an analysis was developed on the space dynamics of the Cariri Region, identifying for each historical moment the agents responsible for the production of space according to each period. It was possible to propose a periodization for the production process of the regional space: the first one marked by the action of the Cariris Indians, a second one structured after the colonization and control of the Municipality of Crato, a third characterized by the rise of the Municipality of Juazeiro of the North and a fourth produced on the basis of the current phase of capitalism and the process of globalization. A third moment concerns the theoretical and empirical analysis of the production process of the Crato-Juazeiro do Norte-Barbalha triangle space. The analysis highlights the importance of the process of globalization and the current dynamics of the capitalist mode of production in the structuring of a new spatial configuration for the Cariri Region. In the production of this new spatial configuration, the state, companies (national and transnational), banks and social classes stand out as agents that command and control the organization of space.
