The aim of this dissertation is to place the phenomenon of the overpopulation of South African prisons in perspective and to rectify the current situation in search of possible solutions. Since 1981, when this phenomenon reached unmanageable proportions, government has made numerous amnesties. This was only a short-term alleviation of the problem due to the high levels of recidivism. Correctional supervision as a sentence option was advocated by both the Lansdowne and Viljoen Commissions, enacted during 1986 and finally implemented during 1991. Initial expectations soon became blurred by factors such as insufficient development programmes and specialised personnel, enormous caseloads and the exclusion of supervision cases from development programmes. This study endeavours to analyse the current application of correctional supervision to determine the stumbling blocks and to create a foundation for new perspectives and possible solutions. / Penology / M.A. (Penology)

This study examines through autoethnographic inquiry my research journey in the world of childhood cancer. The unfolding research experience eventually led to the focus of this investigation which is exploring stories of coping with childhood cancer in a support group for parents. Using the principles of ethnographic epistemology this study explores the stories of eight parents whose children were diagnosed with cancer and who decided to join the support group for parents called, TOUCH. An overview of the existing body of knowledge on childhood cancer and the family is presented as well as the value of a social support group in parenting a child with cancer. The need of a conceptual shift in order to understand the problem of parenting a child with cancer is propagated. The stories of eight parents within the setting of a social support group are presented. Through the principles of the qualitative method of ethnography the story of the child's cancer is described by means of emerging themes. The coping mechanisms used to cope in this world of uncertainty and ambiguity, follows. Finally the contribution of the support group is discussed in terms of my relationship with the group member, the group members' communication pattern and what was perceived to be helpful to the group member. The eight stories discussed all follow the same pattern. Four hypotheses emerged from the eight stories described and are presented in the final chapter. The strengths and limitations of the study are discussed as well as recommendations for future research. / Psychology / D. Lit. et Phil. (Psychology)

Introdução: A Doença Hepática Gordurosa Não Alcoólica (DHGNA) tem como causa principal a obesidade. Atualmente não existe tratamento medicamentoso específico para DHGNA. A cirurgia bariátrica surge como uma alternativa de tratamento em pacientes morbidamente obesos. Objetivos: Analisar, através de biópsia hepática intra-operatória, o grau de comprometimento hepático em obesos submetidos à cirurgia bariátrica, correlacionando os achados histopatológicos com o estado glicêmico dos pacientes. Métodos: Estudo de coorte prospectivo incluindo 521 pacientes submetidos à cirurgia bariátrica de julho de 2001 até dezembro de 2016. Os pacientes foram classificados em três grupos de acordo com o status glicêmico basal: 167(32,05%) diabéticos tipo 2 (G1), 132 (25,33%) pré-diabéticos (G2) e 222 (42,61%) obesos normoglicêmicos (G3). Foram obtidas biópsias hepáticas transoperatórias, as quais foram classificadas conforme os critérios de Brunt e do NASH-CRN. As variáveis clínicas e bioquímicas e histológicas foram comparadas antes da cirurgia e durante o seguimento pós-operatório. Resultados: A prevalência de DHGNA nesta coorte foi de 95%. Não houve diferença quanto ao gênero e IMC entre os grupos. Observaram-se taxas mais altas de fibrose (56,4% G1 vs 29,2% G2 vs 28,6% G3 p<0,001) e Esteatohepatite Não Alcoólica (EHNA) (59,4% G1vs 49,2% G2 vs 36% G3 p <0,001) nos pacientes diabéticos. Apenas 1,5 %, dos diabéticos apresentaram histologia normal (vs 7,76% G2 vs 15,7% G3). / Introduction: Obesity is the main cause of nonalcoholic fatty liver disease (NAFLD), for which there is currently no specific medical treatment. Bariatric surgery is a treatment alternative for morbidly obese patients. Objectives: Use an intraoperative liver biopsy to analyze the degree of liver damage in obese patients submitted to bariatric surgery and correlates the histopathological findings with glucose status. Methods: Prospective cohort study of 521 morbid obese patients undergoing bariatric surgery from July 2001 to December 2016, classified into three groups according to their baseline glucose status: 167 (32.05%) type 2 diabetes (G1), 132 (25.33%) pre-diabetic (G2) and 222 (42.61%) normoglycemic obese (G3). Patients using potentially hepatotoxic medications and a history of ethanol consumption or viral hepatitis were excluded. Intraoperative liver biopsies were obtained and classified in accordance with Brunt and NASH-CRN criteria. Clinical, biochemical and histopathological variables were compared before surgery and during postoperative follow-up. Results: The prevalence NAFLD was 95%. There was no intergroup difference for sex and BMI. Higher rates of fibrosis (56.4% G1 vs. 29.2% G2 vs. 28.6% G3 p<0.001) and nonalcoholic steatohepatitis (NASH) (59.4% G1vs 49.2% G2 vs. 36% G3 p <0.001) were observed in the diabetic patients. Only 1.5 % of diabetics showed normal histology (vs. 7.76% G2 and 15.7% G3).

Advances in breast cancer detection and oncology treatment modalities have prolonged the survival time for the cancer population, which is officially the largest group of cancer survivors among women in the western world, including South Africa (Brem & Kumar, 2011; Fisher, Dolbeault, Sultan & Bredart, 2014; Herbst, 2011; Reyes-Gibby, et al., 2012). In the light of shocking statistics and ever rising numbers of cancer, especially breast cancer, the time is ripe for further research in the domain of psycho-oncology and has motivated the researcher, due to her interest and involvement in breast cancer, to make this her field of research. Despite the need for a bio-psycho-social approach when treating cancer patients there is little literature available on the psychological interventions in South Africa where the majority of research studies previously conducted in South Africa have generally focused on the bio-medical aspects of cancer (Albrecht, 2009; Venter, 2014). To comprehend the paradigm of psycho-oncology, which is the backbone of this study, a theoretical framework was attained from Engel’s humanistic or psychological model (caring) and Pasteur’s biomedical model (curing) (Borrel-Carrio, Suchman, & Epstein, 2004). The primary aim of this study was to explore the lived experiences of breast cancer patients concerning their diagnosis, treatment and survivorship and unique needs for psycho-oncological interventions through their own “voices”. The research was conducted within a qualitative framework with a case study method of inquiry employing open-ended style interviews and psychotherapeutic sessions with five purposely sampled breast cancer patients. Two qualitative questionnaires were also used for triangulation purposes. Transcripts of all the therapeutic sessions were analysed using interpretive analysis where categories and themes were developed and described in full. Findings indicated that in spite the extensive proof that breast cancer causes numerous sexual and psychological complications during active treatment and afterwards, patients still feel that they have no “platform” to express their emotions and sexual issues within the oncology framework, or that there is enough and sufficient assistance to attend to their needs. e The researcher hopes that this study will make a valuable contribution to research in the field of psycho-oncology in South Africa and to indicate new realities of the chronicity of breast cancer and treatment complications that demand psychotherapeutic interventions in cancer care and that the study will initiate new ways of understanding the role of psychology and the psychologist in the medical world of cancer. The researcher hopes that by offering an understanding of participants’ unique experiences of this process, practitioners will have insight when working therapeutically with this population and empower them to have a quality of life, even within the boundaries of their illness. / Psychology / D.
