Bibliography: leaves 166-174. / There is a lack of information suitable for planners and architects to determine the distribution and intensity of solar radiation in urban spaces. New, tall buildings often reduce the quality of their immediate environment by intercepting sunlight before it reaches street level. While planners and the local authority recognise the necessity to rehumanise the city centre and to protect spaces with human appeal, certain squares are under threat of being overshadowed by the redevelopment of old buildings on their perimeter. This study explores an alternative to existing methods for evaluating the distribution and intensity of solar radiation. Greenmarket Square in central Cape Town was selected as a study area where radiometer readings at fifty-four points were made at one minute intervals from sunrise to sunset in midwinter. Several examples of graphical methods of depicting the readings are critically discussed and results of the field work are analysed in depth using one of the methods. An attempt is made to relate observations of solar radiation levels to human use of the Square. In addition to providing specific information necessary for a full understanding of the new procedures suggested, broadly-based background material on the subject of sun and shade in urban spaces is provided.

Bibliography: pages 575-599. / This study of peri-urban development in the Western Cape examines the acquisition and exploitation of property as an important feature in attaining economic power and high social status by upwardly-mobile people in a colonial setting. The choice of Wynberg in the southern Cape Peninsula as a focal point in this process is predicated upon its rapid growth during the nineteenth century in response to the need for a service centre in this comparatively undeveloped area, and the vigorous marketing which followed its recognition as a desirable and convenient place of residence. Its establishment owed much to the presence and requirements of the British military camp at Wynberg, but its continued growth and expansion can be attributed to the activities of the property developers, the efforts of a lively commercial sector and the construction of the Wynberg Railway. This process of residential and economic development is the main theme of the first five chapters of this thesis and is based, inter alia, on intensive primary research in the Cape Town Deeds Office. By 1880 Wynberg had become the centre of a new surge of growth beyond the city limits of Cape Town, eventually achieving smalltown status with its own independent municipality. There were substantial demographic changes in the area and this thesis contends that the multi-faceted development at Wynberg was facilitated both by particular individuals and interest groups. The inequalities in its evolving social formation which included not only landed proprietors but also many landless people, was not unique and was informed by the pervasive colonial belief in the dominance of European organising principles and capitalist market forces in relation to the exploitation of land. Historically, Wynberg resisted incorporation into the metropolitan area because it had achieved a high level of self-sufficiency by the end of the century. The institution of its municipal council and the defence of its independence prior to and after 1913 when the other Peninsula municipalities were amalgamated with Cape Town, forms the second major theme which is examined in Chapters 6 to 9 of this thesis. Its determined struggle to retain its autonomy ended in 1127 when it yielded to financial and other pressures, whereupon it was formally incorporated within the city limits of Cape Town.

Cover title: The role of Dr A. Abdurahman in the modernisation of Islam-oriented schools. / Bibliography: pages 471-494. / This dissertation concerns the modernisation of Islam-oriented schooling in Cape Town and environs whereby Muslim Mission Primary Schools emerge as a socio-cultural compromise between community needs and State school provision policy. It proceeds from the recognition of the cultural diversity that has since the pioneering days characterised the social order of the Mother City. Two religious and cultural traditions have coexisted here in a superordinate and subordinate relationship; one developed a school system for domestication and cultural assimilation, and the other a covert instructional programme for an alternative religious system and behaviour code. The thrust of the argument is that the Islamic community, developed on the periphery of society that excluded non-Christians, were in the main concerned with cultural transmission, first in the homes of Free Blacks during the Dutch regime, and later in the mosques that arose when religious freedom was obtained.

This thesis examines indentured and apprenticed labor in Cape Town between the years 1808 and 1840. Through analysis of primary material such as the South African Commercial Advertiser, the Colonist, and the Mediator, as well as contemporary travel accounts, contracts of indenture and apprenticeship, and an examination of the records of the Cape Town Magistrates, this study explores the attitudes and perceptions towards indentured and apprenticed labor by both employers and indentured and apprenticed servants.This study hopes to add to the existing literature pertaining to nineteenth-century Cape Colony labor. This thesis commences with an examination of the different indenture and apprenticeship systems which existed in Cape Town between the years 1808 and 1840. It explores the issue of how employers and the government sought to maintain a constant supply of labor in the city as the prominence of urban slavery declined. It also discusses the important issue of how employers defined the terms apprentice and indenture. Chapter two explores the topic of child apprenticeship in Cape Town between the years 1812 to 1840, and illustrates that the notion of child apprenticeship was understood in different ways between employers and parents of apprenticed children. Chapter three investigates the stereotypes Cape Town's English speaking employers held towards the city's indentured and apprenticed laborers. The final chapter explores the question of status and incorporation into Cape Town society for the city's indentured and apprenticed laborers, and demonstrates that laborers did not enjoy equal status to the city's slaves.

Bibliography: leaves 258-281. / This study seeks to develop an understanding of the evolution of state policy towards Africans in Cape Town, and to document the resistance engendered by discriminatory and oppressive laws. Utilizing both primary and secondary sources, the thesis describes and analyses complex social problems and political struggles which originated and developed in the period before 1936. By emphasizing the material and political dimensions, as well as the class interests and social categories involved in this uneven process of struggle, the thesis attempts to transcend the limitations not only of functionalist and "conflict pluralist'' perspectives, but also of the more simplistic Marxist formulations propounded within the field of South African urban studies.

Bibliography: leave 85-90. / Health care systems play an important role in maintaining good health in communities. In South Africa, Africans are continually faced with the dilemma of choosing western or traditional values. The literature has shown that African people use both western and traditional systems simultaneously. The South African government is also considering to include traditional healers in the national health policy .This study examines the opinions of African parents or caretakers of children at Red Cross War Memorial Children' s Hospital regarding their use of western and traditional health systems and their opinion regarding their linkage. The research method for this exploratory study was a focus group and structured interview. The results indicated that in the communities from which the respondents were drawn there are many Africans who consult traditional healers. The results further indicated that many Africans consult both western doctors and traditional healers for the same medical problem. The results also indicated that the respondents considered it necessary to link traditional healers to western health settings. Recommendations for future research are included.

Includes bibliography. / School Effectiveness is a relatively new and poorly defined domain for which a structure is proposed, to facilitate future discussion. Three fields within School Effectiveness are identified, namely School Effectiveness Research (SER), School Improvement (SI) and Quality Assurance (QA). Three divisions are identified within each field on the basis of various criteria. SER has methodological generations, Sl is classified by decade, and three themes of QA are described, including performance indicators (Pis). A definition of effectiveness in terms of regression lines is described and the concept of added value or adjusted achievement developed. This study is concerned with the development of Pis for use within a single school to monitor and promote improvement. The context of the study (a model C senior high school in a predominantly white southern suburb of Cape Town) and the data collected is described before a review is made of some of the analyses which could be used to monitor effectiveness. A technique whereby pupil achievement is adjusted (for prior achievement and other background variables) and the residuals (or adjusted achievement) derived from the regressions investigated with one-way A NOVAs is described and tested using various models and subjects. With respect to groups, it is proposed that statistical significance of differences between mean residuals could be used as a PI. With respect to individual pupils, educators could set their own criterion for investigating cases where adjusted achievement is very large or very small. Statistical significance requires interpretation, however, and the role of professional judgement in modelling and monitoring adjusted achievement is discussed. The view that techniques such as regression analysis can only indicate when professional investigation and intervention might be necessary is stressed. It would seem unwise to rank teachers or subjects on the basis of adjusted achievement.

Submitted in fulfillment of the requirements for Masters in Technology: Clinical Technology Durban University of Technology, 2014. / Background The metabolic syndrome (MS) is a clustering of cardiovascular (CV) risk factors and is noted to be increasing globally. Several studies have shown a link between the MS, chronic kidney disease (CKD) and end-stage renal disease (ESRD) possibly through a process of inflammation. Dialysis therapy may increase inflammation and could worsen MS and increase CV risk and diseases in ESRD patients. ESRD has been associated with increased CV disease in dialysis patients. Although there have been several reports on the prevalence of MS from the general population as well as from other specific groups, there are no known studies in South Africa on the prevalence of MS in ESRD patients on chronic dialysis therapy. The prevalence and risk factors for CV diseases are also currently unknown in the dialysis population in Cape Town. Aim The aim of this study was to determine the prevalence of MS in the dialysis population at Groote Schuur Hospital in Cape Town, to determine the effect of dialysis on MS and its traits and to evaluate CV risk in this patient group. Methods A total of 143 prevalent chronic dialysis patients who consented were used for this study. Demographic and relevant clinical details including systolic and diastolic blood pressures, waist and hip circumference and body mass index were obtained from all patients. Blood was drawn in the fasting state for assessment of full lipogram, glucose, ferritin, iron, calcium and phosphate. The metabolic syndrome was defined using the Adult Treatment Panel III (ATPIII) criteria. To determine the impact of dialysis on MS and its traits in our patients, only incident (new) patients starting dialysis were followed up for assessment of MS traits at timed intervals (at baseline, at 6 months and at 12 months) following initiation of chronic dialysis. To evaluate CV risk in this study, common traditional CV risk factors were assessed and were stratified according to number of risk factors as low ( ≤ 1), moderate (2 – 4) or high ( ≥ 4). Relevant statistical methods were used for analysis. Results Of the 143 patients in the study, 67.8% were on haemodialysis (HD) and 32.2% were on peritoneal dialysis (PD). The mean age of all the patients was 38.5 ± 10.4 years. The MS was present in 37.1% of all patients (PD – 52.2%, HD 29.9%; p = 0.015) and the frequency of increased waist circumference and hypertriglyceridaemia were significantly higher in PD patients than HD patients (p < 0.0001 and p = 0.006 respectively). Hypertension was the most prevalent MS trait in all the patients (89.5%) and was also the most prevalent trait in males (92.4%), females (85.9%) and in HD and PD patients (91.3% and 88.7% respectively). The frequency of CV risk was 3.5, 75.5 and 21.0% respectively for low, moderate and high CV risk and there was no difference in CV risk in HD and PD patients. High CV risk correlated with body mass index (BMI), increased waist circumference (WC), hyperphosphataemia, raised calcium – phosphate product, raised parathyroid hormone (PTH) and elevated C-reactive protein (p < 0.05). There was no significant change in MS prevalence or prevalence of MS traits in patients who were followed up irrespective of gender or modality of dialysis (p > 0.05) Conclusion The prevalence of the MS is higher in dialysis patients compared to the general population in South Africa and among dialysis patients, the prevalence is higher in PD than HD patients. Patients with MS have significantly higher CV risk factors than those without MS. Although dialysis therapy appear to have no significant effects on the prevalence of the MS or its traits in this study, the increased prevalence of the MS and CV risk factors may be related to the underlying disease process associated with ESRD. There is therefore an urgent need to identify and treat dialysis patients with the MS in order to reduce CV morbidity and mortality in this group of patients. Further prolonged prospective studies are needed to clarify the impact of dialysis on the MS and its traits in the ESRD population.

Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: HIV infection, substance abuse, and psychiatric disorders are major public health issues in South Africa. Psychiatric disorders and substance-use disorders together have a negative impact on the health outcomes of people living with HIV and AIDS (PLWHA), such as poor adherence to anti-retrovirals (ARVs), HIV disease progression, lower CD4 counts, vulnerability to opportunistic infections, high viral loads, possible drug resistance, and an earlier onset of death. The overall aim of this study was to investigate the relationship between substance abuse practices and the health status and health behaviour of patients attending HIV clinics in the Cape Metropole. The study used a cross-sectional study design for collecting data on hazardous or harmful use of alcohol and problematic drug use, demographic information and health status among patients attending eight HIV clinics in the Cape Metropole. A sub-sample of patients were assessed on the following domains: depression, psychological distress, psychopathology, post-traumatic stress disorder (PTSD), risky sexual behaviour, adherence to ARVs, levels of resilience, levels of social support and patient’s work, family and social functioning. Of the 608, 10% of consecutively selected patients completed an additional psychiatric diagnostic interview (Mini International Neuropsychiatric Interview). The main findings to emerge from this study are: 1. Patients reporting hazardous or harmful use of alcohol and/or drug use are significantly more likely to be non-adherent to ARVs and have lower CD4 counts than their non-substance abusing counterparts 2. Hazardous or harmful use of alcohol has a direct influence on CD4 count resulting in lower CD4 counts and participants being less likely to be on ARVs. 3. Hazardous or harmful use of alcohol has a direct relationship in predicting tuberculosis (TB). 4. Hazardous or harmful users of alcohol and/or problematic drug users are more likely to report psychological distress (anxiety and depression), depression and low levels of family support than their non-using counterparts. 5. Participants who met the criteria for major depression are significantly more likely to be non-adherent to ARVs. 6. Gender, depression, psychological distress, and PTSD were found to be significant determinants of hazardous or harmful use of alcohol. 7. Psychological distress (anxiety and depression) is significant in directly predicting ARV non-adherence. 8. Male participants and those who stopped taking their ARVs were more likely to have lower CD4 counts than female participants and those who did not stop. 9. PTSD was found to predict psychological distress indicating that participants who experienced trauma were more likely to suffer from psychological distress (anxiety and depression) compared to those who did not experience any PTSD. Participants with lower levels of family support were more likely to suffer from psychological distress than those with high levels of family support. / AFRIKAANSE OPSOMMING: MIV infeksie, dwelmmisbruik en geestesversteurings is groot gesondheidskwessies in Suid-Afrika. Geestesversteurings en dwelmmisbruik het gesamentlik 'n negatiewe uitwerking op die gesondheid van mense wat met MIV en VIGS saamleef (PLWHA), soos byvoorbeeld nie-nakoming in die gebruik van antiretrovirale (ARV’s), MIVsiekteverloop, laer CD4-tellings, vatbaarheid vir opportunistiese infeksies, hoë virale ladings, moontlike weerstand teen medikasie en 'n verkorte leeftyd. Die oorkoepelende doel van hierdie studie was om die verhouding tussen dwelmmisbruik en die gesondheidstatus en -gedrag van pasiënte wat MIV klinieke in die Kaapse Metropool besoek, te bestudeer. Die studie het 'n deursnee-ontwerp gebruik om data in te samel oor die nadelige en gevaarlike gebruik van alkohol en problematiese dwelmgebruik, demografiese inligting, en die gesondheidstatus onder pasiënte wat agt MIV klinieke in die Kaapse Metropool besoek het. 'n Subgroep pasiënte geassesseer op die volgende gebiede: depressie, psigologiese angsversteuring, psigopatologie, posttraumatiese stresversteuring (PTSV), riskante seksuele gedrag, nakoming in die gebruik van ARV’s, weerstandigheidsvlakke , vlakke van sosiale ondersteuning, asook pasiënte se werk, familie en sosiale funksionering. Van die 608 deelnemers is 10% van die pasiënte opeenvolgend geselekteer om 'n addisionele diagnostiese psigiatriese onderhoud te ondergaan (Mini International Neuropsychiatric Interview). Die vernaamste bevindinge wat uit die studie gekom het, is: 1. Pasiënte wat nadelige en gevaarlike gebruik van alkohol en/of dwelms rapporteer is beduidend meer geneig om nie die gebruik van ARV’s na te kom nie, en het laer CD4-tellings as hulle eweknieë wat nie dwelms misbruik nie. 2. Die nadelige en gevaarlike gebruik van alkohol het 'n direkte invloed op CD4- tellings wat lei tot laer CD4-tellings en dat pasiënte minder geneig is om op ARV’s te wees. 3. Die nadelige en gevaarlike gebruik van alkohol hou direk verband met die voorspelbaarheid van tuberkulose (TB). 4. Nadelige en gevaarlike gebruikers van alkohol en/of problematiese dwelmgebruikers, is meer geneig om psigologiese angsversteurings (angs en depressie), depressie, en laer vlakke van familieondersteuning te rapporteer as hul niegebruiker-eweknieë. 5. Deelnemers wat aan die kriteria vir ernstige depressie voldoen, is aansienlik meer geneig tot nie-nakoming in die gebruik van ARV’s. 6. Daar is gevind dat geslag, depressie, psigologiese angs en PTSV beduidende bydraende faktore is tot die nadelige en gevaarlike gebruik van alkohol. 7. Psigologiese angsversteurings (angs en depressie) is beduidend om direk die nie-nakoming van ARV’s te voorspel. 8. Manlike deelnemers en diegene wat hul ARV’s gestaak het, was meer geneig om laer CD4-tellings te hê as vroulike deelnemers en diegene wat nie die gebruik van medikasie gestaak het nie. 9. Daar is gevind dat PTSV psigologiese angs voorspel het wat aandui dat deelnemers wat trauma ondervind het, meer geneig was om aan psigologiese angsversteurings (angs en depressie) te ly in vergelyking met diegene wat geen PTSV ervaar het nie. Deelnemers met laer vlakke van familieondersteuning was meer geneig om aan psigologiese angsversteurings te ly as diegene met hoë vlakke van familiebystand.

Thesis (MCom)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The South African fresh fruit export industry is concerned about fruit and financial losses due to temperature breaks within the fresh fruit export cold chain. The Port of Cape Town plays a crucial role in the export process as the majority of fruit reefer containers that are exported through Cape Town are handled by the Cape Town Container Terminal. This study focuses on the container terminal leg of the fresh fruit export process. Observations made in the Cape Town Container Terminal, at shipping lines and exporting companies show that certain procedures are not always followed in the Cape Town Container Terminal and that congestion and ineffective working methods are causing breaks within the fresh fruit export cold chain. Temperature and time data received from Transnet Port Terminals, shipping lines and exporting companies were analysed for the container terminal segment of the export process. From the data analysis it is clear that there are a large number of breaks originating within the container terminal and that the port is not operating efficiently. The study identifies areas of improvement and makes recommendations on improving some of the issues discussed.
