Abstracts in English, Sotho and Afrikaans / The purpose of this study was to explore the classroom practices of Senior Phase Natural Sciences teachers in some of the schools of the Vhembe District. Qualitative case study approach was employed and three teachers participated. The following research questions were explored: What is the level of the teacher’s subject-matter knowledge in the teaching of Natural Sciences (NS)? What is the nature of the teacher’s instructional strategies in the teaching of NS? How does the teacher’s subject-matter knowledge and instructional strategies shape the teachers’ classroom interaction and discourse in the teaching of NS? Interviews, observations and a questionnaire have been used for data collection. Teachers used their teaching experiences to teach NS. Results indicated lack of teachers, facilities and resources. It is recommended that the Department of Education as an arm of government should see that schools have the facilities, resources and teachers they need for proper teaching and learning as well as providing sufficient workshops to improve teachers’ classroom practices. / Sepheo sa thuto ena e ne e le ho hlahloba mekhoa ea litlelase tsa matichere a Phahameng ea Setsebi sa Tlhaho ea Setsebi tse ling tsa sekolo sa Vhembe.

Abstracts in English, Afrikaans and Southern Sotho / The prevalence of hate victimisation in South Africa remains unknown, as does its full impact. Anecdotal evidence, borne out by recent research findings, suggests hate-based attacks on non-nationals have increased in recent years, distinctly reflecting a picture of heightened vulnerability. For several reasons, the severity of such victimisation, and their physical and psychological impact, go mostly unseen. Hate-motivated incidents, such as hate speech and intentional unfair discrimination, are possible precursors to additional criminal victimisation. Records of such incidents can be helpful to demonstrate both a context of harassment and evidence of escalating patterns of violence. Worldwide, under-reporting of hate victimisation is a longstanding concern and requires an urgent solution. In South Africa, under-reporting has contributed to the nonrecognition of hate crime as a separate crime category. Towards aiding in finding a solution, this study explored the psychological barriers to reporting xenophobic victimisation to relevant authorities. The study, furthermore, explored with a group of victims who experienced xenophobia whether they reported victimisation, the reasons for reporting and under-reporting, and their thoughts and opinions on the workability of a third-party reporting mechanism. Non-probability sampling, specifically applying convenience and purposive sampling was used to obtain 19 participants for the four semi-structured focus groups. While all participants reported being victimised because of their nationality, the study found that multiple psychological barriers prevent such victims of xenophobia from reporting victimisation to authorities. Many of the participants do not believe in the workability of third-party reporting mechanisms. / Dit is onbekend hoe algemeen viktimisering op grond van haat in Suid-Afrika voorkom, en daarom ook wat die volle impak daarvan is. Onlangse navorsingsresultate dui egter daarop dat aanvalle op nielandsburgers wat uit haat voortspruit, toegeneem het die afgelope paar jaar, wat hulle groter kwesbaarheid duidelik weerspieël. Die intensiteit van hierdie viktimisering, asook die fisieke en sielkundige impak daarvan word in die meeste gevalle om verskeie redes ook nie bekendgemaak nie. Voorvalle wat uit haat voortspruit, soos haatspraak en doelbewuste onregverdige diskriminasie, is moontlik voorlopers van verdere kriminele viktimisering. Die optekening van sulke gevalle kan help om bewys te lewer van die teisteringskonteks, sowel as van patrone van toenemende misdaad. Die gebrekkige aanmelding van viktimisering op grond van haat is wêreldwyd lank reeds ’n probleem, en een waarvoor daar dringend ’n oplossing gevind moet word. In Suid-Afrika het gebrekkige aanmelding daartoe bygedra dat haatmisdaad nie as ’n aparte misdaadkategorie erken word nie. Ten einde ’n oplossing te help vind, het die navorser vir die doeleindes van hierdie studie die sielkundige faktore ondersoek wat verhoed dat xenofobiese viktimisering by die betrokke owerhede aangemeld word. Die studie bevat ook die terugvoer van ’n groep slagoffers van xenofobie oor hulle aanmelding van die viktimisering al dan nie, die redes waarom hulle dit aangemeld het of nie aangemeld het nie, en hulle gedagtes en menings oor hoe lewensvatbaar ’n stelsel vir derdeparty-aanmelding is. Niewaarskynlikheid-steekproefneming, en spesifiek doelbewuste en gemaksteekproefneming is gebruik om 19 deelnemers vir die vier semigestruktureerde fokusgroepe te vind. Alhoewel al die deelnemers bevestig het dat hulle geviktimiseer is op grond van hulle nasionaliteit, het die navorser met hierdie studie bevind dat verskeie sielkundige faktore die slagoffers van xenofobie verhoed om die viktimisering by die owerhede aan te meld. Talle van die deelnemers glo nie dat stelsels vir derdeparty-aanmelding ’n werkbare oplossing is nie. / Hore na tshwaro e mpe ka lebaka la lehloyo e atile hakae Afrika Borwa ho ntse ho sa tsejwe, le ditlamorao tsa yona ha di tsejwe.

Abstract in English, Afrikaans and Sesotho / Scuba diving is a popular marine recreational activity along the eastern and southern coast of Africa. This region is characterised as the East African Marine Ecoregion (EAME) and is known for its richness in marine fauna and flora, including some of the Indian Ocean‟s most diverse and abundant coral reef ecosystems, making it a popular destination for scuba divers. The future of the scuba diving industry has come under threat as a result of environmental, social, political and economic impacts, and there is a need to better understand how these external risks impact on scuba diving tourism businesses in the EAME. Empirical evidence suggests that external risks, both international and domestic, have an effect on the tourism industry as a whole. However, limited research has been conducted on the impact of such external risks on the dive tourism industry specifically. Existing research has also focused extensively on environmental risks rather than on how external risks of a political, economic and social nature affect dive operator sustainability in the EAME. Most studies have also focused on the demand side (divers) as opposed to the supply side (dive operators). In addition, as dive tourists have greater flexibility to change their destination should risks arise, this threatens the success of dive operators in higher risk areas. To address these problems, the primary objective of the research undertaken sought to comprehensively identify the impact of external risks (environmental, economic, social and political) on dive operators in four countries within the EAME from a supply-side perspective. In order to achieve the primary objective, the following secondary objectives were achieved: 1. Identified scuba diving tourism operators in the EAME and their scope of operation. 2. Determined the external risks most relevant to dive operators in the EAME and assessed their level of impact. 3. Compared the individual external risks experienced by each of the countries in the EAME (Kenya, Tanzania, Mozambique and South Africa) using a cross-case analysis. 4. Assessed the perception of dive operators regarding whether external risks would influence a dive tourists decision to travel to the dive operators area of operation in the EAME ii The study consisted of two phases. Phase 1 comprised structured interviews with a select group of dive operators to gain insight into the external risks most prevalent in the scuba diving industry, as well as to assist in developing a quantitative structured survey (Phase 2), which was subsequently completed by dive operators in Kenya, Tanzania, Mozambique and South Africa. Data was imported into SPSS for quantitative statistical analysis. From the primary data collected, the major findings from this study determined that current economic and political risks have the greatest impact on dive operators in the EAME, and this trend is expected to continue. Environmental degradation of coral reefs, while not seen as a threat at present, constitutes a key threat for the near future. The greatest influences expressed in terms of risk categories impacting on dive tourism are domestic economic risks, international economic risks, domestic political risks and international political risks. A cross-case analysis conducted on the four countries concluded that external risks have varying effects within the different countries. Finally, the results indicated that external risks significantly influence a dive tourist's decision to travel to the EAME. By identifying and assessing the external risks that have an impact on dive operators in the EAME, this research contributes to knowledge on the dive tourism industry in the EAME, as well as dive tourism further afield and the wider field of tourism management. The study's findings create awareness of the effect that external risks have on dive operators in the region. A conceptual framework was developed which encompasses external risks in the scuba diving industry. Risk radars, risk maps and colour-coded tables were further outputs this study which can assist businesses, society and economies in responding to current and future threats and crises in a more informative and intuitive way. This can be achieved by implementing risk management strategies to mitigate or reduce exposure to external risks; strengthening stakeholder involvement along the tourism value chain; and stressing the need for government involvement towards the protection of the environment and promotion of small business growth in the region. Future research can include a wider view of the marine tourism industry and other areas of the Blue Economy. / Skubaduik is 'n gewilde mariene ontspanningsaktiwiteit langs die oos- en suidkus van Afrika. Hierdie streek staan bekend as die Oos-Afrika Mariene Ekostreek (East African Marine Ecoregion, EAME) en is bekend vir sy rykheid aan mariene fauna en flora, insluitende sommige van die Indiese Oseaan se mees diverse en welige koraalrif-ekostelsels, wat dit 'n gewilde bestemming vir skubaduikers maak. Die toekoms van die skubaduikbedryf word bedreig weens die impak van omgewings-, sosiale, politieke en ekonomiese gebeure, en daar is 'n behoefte om beter te verstaan hoe hierdie eksterne risiko's skubaduiktoerisme-besighede in die EAME beïnvloed. Empiriese bewyse suggereer dat eksterne risiko's, internasionaal sowel as plaaslik, 'n invloed op die toerismebedryf as 'n geheel het. Beperkte navorsing is egter gedoen oor die impak van sulke eksterne risiko's op spesifiek die duiktoerisme-bedryf. Bestaande navorsing het ook uitvoerig gefokus op omgewingsrisiko's eerder as hoe eksterne risiko's van 'n politieke, ekonomiese en sosiale aard duik-operateur-volhoubaarheid in die EAME beïnvloed. Die meeste studies het ook gefokus op die aanvraagkant (duikers) in teenstelling met die aanbodkant (duik-operateurs). Verder, omdat duiktoeriste meer buigsaamheid het om hulle bestemming te verander indien risiko's voorkom, bedreig dit die sukses van duik-operateurs in hoë-risiko-gebiede. Om hierdie probleme te hanteer is die primêre doel van die navorsing wat gedoen is om op omvattende wyse die impak van eksterne risiko's (omgewing, ekonomies, sosiaal en polities) op duik-operateurs in vier lande in die EAME te identifiseer uit 'n aanbodkant-perspektief. Om die primêre doelwit te behaal, is die volgende sekondêre doelwitte bereik: 1. Skubaduik-toerisme-operateurs in die EAME en hulle operasionele omvang is geïdentifiseer. 2. Die eksterne risiko's wat die relevantste vir duik-operateurs in die EAME is, is bepaal en hulle vlak van impak is geassesseer. 3. Die individuele eksterne risiko's wat deur elkeen van die lande in die EAME (Kenia, Tanzanië, Mosambiek en Suid-Afrika) ervaar is, is vergelyk deur die gebruik van 'n kruisgeval-analise. 4. Die persepsie van duik-operateurs wat betref of eksterne risiko's 'n duiktoeris se besluit sal beïnvloed om na die duik-operateur se operasionele gebied in die EAME te reis, is geassesseer. Die studie het uit twee fases bestaan. Fase 1 het gestruktureerde onderhoude met 'n geselekteerde groep duik-operateurs behels om insig te kry in die eksterne risiko's wat die algemeenste in die skubaduikbedryf voorkom, en om te help om 'n kwantitatiewe gestruktureerde peiling (fase 2) te ontwikkel, wat gevolglik deur duik-operateurs in Kenia, Tanzanië, Mosambiek en Suid-Afrika voltooi is. Data is ingevoer in SPSS vir kwantitatiewe statistiese analise. Uit die primêre data wat ingesamel is, het die belangrikste bevindings van hierdie studie bepaal dat die huidige ekonomiese en politieke risiko's die grootste impak op duik-operateurs in die EAME het, en daar word verwag dat hierdie tendens sal voortduur. Die omgewingsagteruitgang van koraalriwwe, hoewel dit nie tans as 'n bedreiging beskou word nie, is 'n sleutelbedreiging vir die nabye toekoms. Die grootste invloede wat uitgedruk is as risiko-kategorieë wat 'n invloed op duiktoerisme het, is plaaslike ekonomiese risiko's, internasionale ekonomiese risiko's, plaaslike politieke risiko's en internasionale politieke risiko's. 'n Kruisgeval-analise wat op die vier lande uitgevoer is, het bevind dat eksterne risiko's wisselende uitwerkings binne die verskillende lande het. Laastens het die resultate aangedui dat eksterne risiko's 'n duiktoeris se besluit om na die EAME te reis, aansienlik beïnvloed. Deur die eksterne risiko's te identifiseer en te assesseer wat 'n impak op duik-operateurs in die EAME het, dra hierdie navorsing by tot kennis oor die duiktoerismebedryf in die EAME, asook duiktoerisme verder weg en die wyer veld van toerismebestuur. Die studie se bevindings skep 'n bewustheid van die uitwerking wat eksterne risiko's op duik-operateurs in die streek het. 'n Konseptuele raamwerk is ontwikkel wat eksterne risiko's in die skubaduikbedryf omvat. Risiko-radars, risiko-kaarte en tabelle wat volgens kleur gekodeer is, was verdere uitsette van hierdie studie wat besighede, die gemeenskap en ekonomieë kan help om te reageer op huidige en toekomstige bedreigings en krisisse op 'n meer ingeligte en intuïtiewe manier. Dit kan bereik word deur risikobestuurstrategieë te implementeer om blootstelling aan eksterne risiko's te mitigeer of te verminder; belanghebberbetrokkenheid op die toerismewaardeketting te versterk; en om die behoefte vir regeringsbetrokkenheid by die insluit. / Ho sesa tlasa metsi a lewatle ke mosebetsi o tsebahalang haholo wa boithabiso ba lewatle haufi le mabopo a ka botjhabela le borwa ba Afrika.

The focus of this study was on teacher’s knowledge about environmental education, instructional strategies used and challenges and opportunities experienced when they have to integrate environmental education. The study adopted a qualitative research method, case study design and an interpretative research paradigm. Qualitative data was collected using interviews and lesson observations. Three teachers participated in this study. Pseudonyms were used to protect their identities. A typology approach was utilised to analyse data based on the research questions, themes, conceptual framework, literature review and the personal experience of the researcher. All data collected was analysed and interpreted as a single case using. The study revealed that environmental education is not integrated effectively, teachers who integrate and those that do not integrate encountered challenges and that teachers have inadequate knowledge about the integration of environmental education. Therefore, it is recommended that the school together with teachers introduce continuous environmental education programmes and suggests approaches that can be used to improve their instructional strategies to enable the intergration of environmental education effectively. / Science and Technology Education / M.

Vietnam is a populous nation experiencing rapid social and economic transition. These changes, in combination with the spread of sexually transmitted infections such as HIV/AIDS, are compromising the reproductive health of young Vietnamese. Access to reliable reproductive health information is limited and social taboos prevent young people from talking openly about this topic. A huge number of young people living in Vietnam thus find themselves without access to relevant, accurate, non-threatening and unbiased information about sexuality and sexual health. The research outlined in this thesis approaches the issue of sexual health information provision for young people living in Vietnam from a participatory action research foundation. A key focus is investigation of the ways in which young people living in Vietnam can be included in the development of online sexual health communication tools by, for and about young Vietnamese. As part of this investigation, this thesis describes research conducted with young Vietnamese in Australia and Vietnam to identify and elucidate their reproductive health information needs, as situated within the contemporary Vietnamese socio-cultural context. The research was undertaken in order to determine how an online resource might meet these needs. This exploratory process involved the utilisation of a range of research methods to determine the website's optimal content, style, features and tone in relation to the Vietnamese context and requirements of its target users. It is hoped that the record of discovery resulting from this research journey will contribute to the existing body of knowledge on online health communication and participatory approaches to the development of context-sensitive health and behaviour-change communication.

Vietnam is a populous nation experiencing rapid social and economic transition. These changes, in combination with the spread of sexually transmitted infections such as HIV/AIDS, are compromising the reproductive health of young Vietnamese. Access to reliable reproductive health information is limited and social taboos prevent young people from talking openly about this topic. A huge number of young people living in Vietnam thus find themselves without access to relevant, accurate, non-threatening and unbiased information about sexuality and sexual health.

The wall thickness of pulp fibers plays a major role in the paper industry, but it is currently not possible to measure this property without manual laboratory work. In 2007, researcher Ho Fan Jang patented a technique to automatically measure fiber wall thickness, combining the unique optical properties of pulp fibers with image analysis. In short, the method creates images through the use of an optical system resulting in color values which demonstrate the retardation of a particular wave length instead of the intensity. A device based on this patent has since been developed by Eurocon Analyzer. This thesis investigates the software aspects of this technique, using sample images generated by the Eurocon Analyzer prototype. The software developed in this thesis has been subdivided into three groups for independent consideration. First being the problem of solving wall thickness for colors in the images. Secondly, the image analysis process of identifying fibers and good points for measuring them. Lastly, it is investigated how statistical analysis can be applied to improve results and derive other useful properties such as fiber coarseness. With the use of this technique there are several problems which need to be overcome. One such problem is that it may be difficult to disambiguate the colors produced by fibers of different thickness. This complication may be reduced by using image analysis and statistical analysis. Another challenge can be that theoretical values often differ greatly from the observed values which makes the computational aspect of the method problematic. The results of this thesis show that the effects of these problems can be greatly reduced and that the method offers promising results. The results clearly distinguish between and show the expected characteristics of different pulp samples, but more qualitative reference measurements are needed in order to draw conclusions on the correctness of the results.

This thesis deals with designing of C axis for interchangeable heads for milling machining centres with horizontal spindle centre of the slide type. Itâs divided into three parts, whereas the first part contains theoretical introduction to the problematic. The second part deals with systematic analysis of the topic and choosing the right variant for elaboration. The last part forms construction design of the chosen variant, which contains notes on the solution proce-dure, calculations and visualization in form of 3D models.
