Prostitution is the oldest form of oppression. Many prostituted women in South Africa wish to exit sex work, but are unable to because they have no other means of earning money. There is a dearth of research available on assisting prostituted women to exit sex work in South Africa. This study explored the effectiveness of a Cape Town-based NGO's - Embrace Dignity - exit intervention for prostituted women. Using semi-structured interviews it investigated the experiences of eight prostituted women in Cape Town. The research goal was to be able to inform improvements to the intervention for exit. An interpretative phenomenological approach was used to analyse interviews of women's experiences of the intervention. Findings revealed that attempting to exit prostitution in South Africa is an incredibly difficult and deeply complex process. An exploration of women's experiences of Embrace Dignity suggested that whilst it provides emotional and social support to prostituted women, it does not address their physical needs, most importantly that of employment. This study reveals that although emotional support plays a crucial role in assisting prostituted women to exit, it is secondary to the urgent physical support needed to satisfy the basic survival needs of prostituted women living in extreme poverty in South Africa.

The purpose of this study was to develop a set of guidelines to enable teachers to support children with diabetes. The aspects of support include the physical, emotional, social and cognitive aspects that have an effect on a child with diabetes. A literature study and an empirica l investigation were und ertaken to investigate which factors would enable teachers to become better sources of support in school. Semi - structured interviews were conducted with teachers to determi ne their knowledge about diabetes . Parents who have children with diabetes were also interviewed to determine what support they required from teachers. The results of the study culminated in a set of guidelines for teachers. / Psychology of Education / M. Ed. (Psychology of Education)

L’Organisation Mondiale de la Santé (OMS) a fixé en 1998 la concentration maximale en arsenic dans l’eau de consommation à 10 ppb (μg/L). Dans le monde, plus de 100 millions de personnes sont exposées à des concentrations supérieures à 50 ppb. La toxicité, l’omniprésence et la mobilité de l’arsenic entraînent la nécessité de pouvoir le doser immédiatement sur le terrain. Il existe actuellement deux méthodes de dosage de terrain commercialisées. La première, onéreuse, est basée sur la voltammétrie (> 7000 €). La seconde à environ 2 €/analyse se présente sous le format de bandelette. Elle permet la mesure de teneurs en arsenic avoisinant les 10 ppb, mais nécessite la génération d’arsine (forme la plus toxique), l’utilisation de bromure de mercure et donne jusqu’à 33% de faux positifs. L’entreprise Novassay souhaite développer une nouvelle méthode de dosage de l’arsenic simple, rapide et efficace pouvant être utilisée directement sur le terrain. Ce travail présente dans un premier temps, un nouveau protocole issu d’une optimisation de la méthode dite au bleu de molybdène et de l’utilisation d’une membrane filtrante permettant une lecture colorimétrique sur support solide. Dans un deuxième temps, seront présentés les résultats obtenus sur le développement d’une méthode de dosage inédite de l’arsenic par l’intermédiaire de nanoparticules d’or. Dans cette partie, une molécule imaginée à partir de la structure d'un complexant naturel de l’arsenic sera synthétisée. Les tests de dosage de l’arsenic avec cette molécule seront réalisés sur deux types de nanoparticules d’or, les premières stabilisées au citrate, les secondes stabilisées au xylane. / In 1998, the World Health Organization (WHO) set the maximum concentration of arsenic in drinking water at 10 ppb (μg/L). In the world, more than 100 million people are exposed to concentrations upper than 50 ppb. The toxicity, ubiquity and mobility of arsenic imply the need to be able to dose it immediately on the field. There are currently two commercially available field dosing methods. The first, expensive, is based on voltammetry (> €7000). The second at about €2/analysis is available in the strip format. It allows the measurement of arsenic concentrations close to 10 ppb but requires the generation of arsine (the most toxic form of arsenic), the use of mercury bromide and gives up to 33% false positives. Novassay wants to develop a new simple, fast and efficient arsenic method that can be used directly in the field. Firstly, this work shows a new protocol resulting from an optimization of the molybdenum blue method and the use of a filtering membrane allowing a colorimetric reading on a solid support. In the second part of this work, the results obtained on the development of a novel method of dosing arsenic by the utilisation of gold nanoparticles will be presented. In this part, an imagined molecule from the structure of a natural complexant of arsenic will be synthesized. The arsenic assay with this molecule will be performed on two types of gold nanoparticles, the first stabilized with citrate, the second stabilized with xylan.
