Thesis (MNutr)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Introduction and Objectives: Schools can serve as a supportive environment for the promotion of healthy eating in order to prevent childhood overweight and obesity and the development of noncommunicable diseases such as cardiovascular diseases, type 2 diabetes mellitus, fatty liver disease, muscoskeletal disorders and some cancers. Tuck shops at schools often offer unhealthy items that are energy dense and high in fat and/or sugar with a low content of vitamins, minerals and dietary fibre. The availability of unhealthy items in tuck shops prevents learners from making healthy food choices, since children tend to choose unhealthy foods when given a choice. In addition to unhealthy items offered by tuck shops, learners also bring unhealthy items to school in their lunchboxes. The aim of the study was to investigate the influence of a nutritionally-regulated tuck shop on primary school learners’ perceptions, attitudes and behaviour towards healthy eating in a Bloemfontein, Afrikaans medium, co-education primary school, and compare it to learners of a school with a conventional tuck shop. Methods: In a cross-sectional survey with an analytical component, grade 2 to 7 learners in a school with a nutritionally-regulated tuck shop (n=116) and a school with a conventional tuck shop (n=141) completed a questionnaire. Six learners per grade also took part in focus group discussions. Questions related to lunchbox contents and perceptions, attitudes and behaviour towards the tuck shop and healthy eating. Nutritional information of the items available for purchase at each of the school tuck shops was collected. Results: The lunchboxes of learners in the school with a nutritionally-regulated tuck shop contained significantly (p<0.05) more healthy items (fruit, water and muffins), as well as significantly more unhealthy items (sweets and chips). The items offered by the nutritionally-regulated tuck shop contained approximately half the kilojoules compared to items offered by the conventional tuck shop. Learners in the school with a nutritionally-regulated tuck shop liked certain fruits and vegetables significantly (p<0.05) more than learners in the school with a conventional tuck shop. Statistical significant differences (p<0.05) between different grades and gender showed that grade 2 learners in both schools had a less positive attitude towards certain fruit and vegetables compared to the older learners, while girls in both schools were more positive towards certain fruits and vegetables compared to boys. Younger learners had a more positive attitude towards their nutritionally-regulated tuck shop than older learners. In both schools learners had similar perceptions regarding the particular school’s tuck shop and healthy eating. Conclusion: The hypothesis that learners in a school with a nutritionally-regulated tuck shop have positive attitudes, perceptions and behaviour towards healthy eating was rejected. The availability of healthier items in a school tuck shop had a positive influence on certain behaviours and attitudes of learners, but the potential value of controlling the type of items available for purchase at schools might be counteracted by lunchbox contents, certain fixed eating patterns, perceptions of learners and previous exposure to a conventional tuck shop. Recommendations include a multi-pronged approach such as the Health Promoting Schools concept. / AFRIKAANSE OPSOMMING: Inleiding en doelwitte: Skole bied ‘n omgewing waar goeie eetgewoontes bevorder kan word ten einde oorgewig en vetsug in kinders te voorkom, asook die ontwikkeling van nie-oordraagbare siektes soos kardiovaskulêre siektes, tipe-2 diabetes mellitus, lewervervetting sindroom, ortopediese komplikasies en sekere soorte kanker. Snoepies in skole voorsien meestal ongesonde items met ‘n hoë energie, vet- en/of suikerinhoud en wat laag is in vitamiene, minerale en dieetvesel. Die beskikbaarheid van ongesonde items in snoepies verhoed dat leerders gesonde voelselkeuses uitoefen, omdat kinders geneig is om voorkeur aan ongesonde kos te gee as hulle 'n keuse gebied word. Benewens die ongesonde items wat snoepies aanbied, neem leerders boonop ongesonde kos in hul kosblikke skooltoe. Die doel van die studie was om by 'n Afrikaans dubbelmedium laerskool in Bloemfontein die invloed van ‘n voedingkundig-gereguleerde snoepie op leerders se persepsies, houdings en gedrag teenoor gesonde eetgewoontes te ondersoek en te vergelyk met leerders in 'n skool met 'n konvensionele snoepie. Metodes: In ‘n deursnit-opname met ‘n analitiese komponent, het graad 2 tot 7 leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie (n=116) en ‘n skool met ‘n konvensionele snoepie (n=141), ‘n vraelys ingevul. Ses leerders in elke graad in elk van die skole het ook aan fokusgroepbesprekings deelgeneem. Vrae het oor die inhoud van kosblikke, asook persepsies, houding en gedrag teenoor die snoepie en gesonde eetgewoontes, gehandel. Voedingsinligting rakende die items wat in elk van die skole se snoepies verkoop word, is ook ingesamel. Resultate: Die kosblikke van leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie het statisties beduidend (p<0.05) meer gesonde items bevat (vrugte, water en muffins), maar ook beduidend meer ongesonde items (lekkergoed en aartappelskyfies). Voedsel-items wat in die voedingkundig-gereguleerde snoepie beskikbaar was, het omtrent die helfte minder energie bevat as voedsel-items wat in die konvensionele snoepie beskikbaar was. Leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie het beduidend (p<0.05) meer van sekere groente en vrugte gehou as leerders in ‘n skool met ‘n konvensionele snoepie. Statisties beduidende (p<0.05) verskille tussen verskillende grade en die houding van verskillende geslagte dui daarop dat graad 2 leerders in albei skole minder positief gevoel het oor sekere groente en vrugte as ouer leerders, terwyl meisies in albei skole ‘n meer positiewe houding teenoor sekere groente en vrugte getoon het as seuns. Jonger leerders het ‘n meer positiewe houding teenoor hulle voedingkundig-gereguleerde snoepie getoon as ouer leerders. In albei skole het leerders soortgelyke persepsies rondom hul onderskeie skole se snoepies en gesonde eetgewoontes openbaar. Gevolgtrekking: Die hipotese dat leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie positiewe persepsies, houding en gedrag teenoor gesonde eetgewoontes toon is nie aanvaar nie. Die beskikbaarheid van gesonder items in ‘n skoolsnoepie het 'n positiewe invloed op sekere eetgewoontes en houdings van die leerders, maar die potensiële waarde daarvan om die tipes voedsel wat by skole te koop aangebied word te reguleer mag egter teengewerk word deur kosblikke se inhoud asook sekere vaste eetpatrone, persepsies van leerders en vorige blootstelling aan ‘n konvensionele snoepie. ‘n Veelvoudige benadering soos die konsep van ‘n Gesondheidbevorderingskool word aanbeveel.

Descreve e analisa o modo de atuação dos líderes do movimento indígena, a partir das experiências exemplares indígenas vivenciadas no contexto interétnico do Vale do Javari. Aborda a criação do Conselho Indígena do Vale do Javari (CIVAJA), como organização protagonista de acontecimentos da história do movimento indígena. Como instrumento de análise, recorre à noção de rede para tratar as relações entre os atores sociais como múltipla e não apenas uni-direcional. A criação de organizações indígenas é tratada como parte do processo de definição de espaços interculturais no Estado brasileiro. Sob a abordagem do diálogo intercultural, questiona se a participação indígena nas esferas públicas governamentais de atuação tem permitido a articulação entre os distintos sistemas de significados ou tem mantido o predomínio hierárquico do sistema não-indígena. Ao final, conclui que, apesar da pluralidade étnica ser reconhecida pela sociedade brasileira, não se criou meios para concretizá-la como princípio organizativo do Estado nacional / Abstract: This dissertation deals with the indigenous movement in Brazil after the promulgation of the Constitution of 1988, when a new phase began and significant changes took place in the political and juridical forms of insertion of the indigenous populations into the Brazilian state. It describes and analizes the role of the indigenous movement¿s leaders based on the example of indigenous experiences witnessed in the interethnic context of the Vale do Javarí. It discusses the process of creation of the Indigenous Council of the Vale do Javarí (CIVAJA) as an organization active in various events in the history of the indigenous movement. The thesis adopts the notion of network as an analytical instrument, in order to capture the relationships between social actors as multiple rather than unidirectional processes. The creation of indigenous organizations is analyzed as part of the process of definition of intercultural spaces within the Brazilian state. From a perspective of intercultural dialogue, the study moves toward questioning whether the indigenous participation in the governmental public spheres has permitted exchanges between the different systems of meaning, or if it has left the hierarchical predominance of the non-indigenous system in place. Eventually, the dissertation concludes that despite the recognition of ethnic plurality by Brazilian society, means of substantiating that recognition into a concrete organizational principle of the nation-state have not been devised. / Doutorado / Doutor em Ciências Sociais

Despite there being general agreement that SMEs are valuable in the global and South African economy to aid in creating jobs and in growing the economy, few benefits accrue to these enterprises as they endure a number of challenges which make them unsustainable. This research aimed to investigate the sustainability of SMEs in Tshwane townships, with an aim to design a framework that could be used by other SMEs that intend to enter the tourism industry, to ensure that they are sustainable and can contribute towards the expansion of the South African economy. The primary data was collected through a questionnaire, which was used to obtain information on Tshwane township tourism SMEs, as a way of detecting whether they were sustainable or not. The results indicated that the Tshwane township tourism SMEs were very small enterprises created by owners who were passionate about the tourism product. These enterprises have not been able to grow and employ more people but have provided employment and survival income for the owner and, in some cases, two additional people. SMEs face various challenges relating to sustainability, one of the main challenges being financial stability. SMEs are therefore unable to play their intended role in the creation of employment as well as in contributing to the economy as a whole. In an attempt to assist the owners and/or managers of SMEs to fulfil their roles, an SME framework was developed in the course of the present research. This framework comprises a step-by-step guide that asks all the relevant questions aimed at getting to know the business and culminating in a range of recommendations that could assist in making these SMEs sustainable. / Entrepreneurship and Supply Chain, Transport, Tourism and Logistics Management / M.
