This pilot study consists of two parts. The first part investigates the extent to which the domestic electricity consumers intend to use and use energy efficiently using the Theory of Planned Behaviour. The second part investigates the extent to which the Energy @ Home educational intervention changed the domestic electricity consumers’ behaviour. For the first part of the study an advertisement was published and a convenience stratified sample of 61 domestic electricity consumers were selected from the 290 respondents. Data was collected from the domestic electricity consumers via a questionnaire and a telephone response log. The co-relational research design was used to investigate the relationship between the predictor variables the independent variables in the constructs of the Theory of Planned Behaviour. Simple linear regression analysis resulted in F statistic for the predicted behavioural intention was 29.74 with a p value less than 0.0001 which indicates significant statistical evidence of a linear relation between the predictor variables and the independent variables. The r2 of 0.87 implies that data points that fall closely along the best fit line. Therefore the predictor variables were good predictors of the response variable. All the participants that intended to use electricity efficiently confirmed via the telephone that they were using electricity efficiently. In the second part of the study 11 out of the 61 participants were chosen to participate in the Energy @ Home educational intervention and television program. Data was collected via the Energy audit log and the electricity consumption log. The participants intended to save between 2% and 35% of their electricity consumption and the actual electricity consumption savings were between 2% and 30%. / Science and Technology Education / M.

Most research in green IT tend to focus on the practices of large IT vendors and companies. There is therefore a need to examine the beliefs and actual behaviour of IT users about green IT, as it significantly impact of energy consumption and computer design on the broader society. The main question to be answered was ―Are IT users generally concerned with regards to green IT issues?‖. Therefore the main purpose of this study was thus to evaluate the beliefs and actual behaviour of IT users regarding green IT in South Africa through a survey that was completed by university students and lecturers. The paucity of available research on this subject pertaining to South Africa justifies the importance of conducting this study. A hypothesised research model based on the theory of planned behaviour (TPB) was used to evaluate the main factors contributing to green IT awareness in an empirical study. A mixed research method was used as the paradigm which combines aspects from both interpretive and positivist research approaches. A questionnaire was used to collect data from university students and lecturers. The data was captured and analysed for convergent validity. The reliability of measurement items was tested using Cronbach‘s alpha. Structural Equation Modelling was used to model latent variables under conditions of non-normality. Subjective norm was the main factor contributing to intended belief and actual behaviour / School of Computing / M.A. (Computer Science)

Despite HIV and AIDS knowledge and attitude change programmes, workplace HIV and AIDS-related discrimination persists in workplaces in many sectors, including the education sector. This study set out to investigate why the phenomenon of workplace HIV and AIDS-related discrimination persists; and to predict which factors were responsible and how they related to HIV and AIDS-related discrimination in the workplace. A stratified random sample of 205 teachers; 123 of whom were from 10 schools of varied backgrounds in Bojanala Region of North West Province of South Africa and 82 from schools around Kampala, Central Region of Uganda was drawn. Twenty-seven respondents of the South African sample participated in both the quantitative survey and in-depth interview while the rest responded to a selfadministered questionnaire. Using a stepwise regression analysis, traditional beliefs predicted workplace HIV and AIDS-related discrimination, explained11% of variance in the second model while the third model explained only 2% more – 13% (R square of 0.136) but each of the three models was significant (p-values of 0.000). Attitudes were the second strongest predictor; and only HIV and AIDS-legal knowledge could predict discrimination but not biomedical HIV and AIDS knowledge. In the in-depth interview, incidents of discrimination were reported, possible reasons for HIV and AIDS-related discrimination were reported; and it was found that workers varied in ways of keeping secrets regarding sensitive information such as colleagues’ HIV-positive status, and cited reasons for revealing such information which included malice, jealousy, moral responsibility, anger and loose talks. There are implications for reducing workplace HIV and AIDS-related discrimination which include: Integrating HIV and AIDS-legal knowledge with biomedical HIV and AIDS knowledge, more efforts should be spent in designing and imparting information to reduce traditional beliefs, develop and evaluate instruments to measure traditional beliefs and HIV and AIDS-legal knowledge; and to study more about secret keeping, particularly in regard to workplace HIV and AIDSrelated discrimination. / Industrial & Organisational Psychology / D.

Small businesses, particularly growing small businesses, are regarded by policy makers and academics alike as being important sources of wealth creation, employment generation and innovation. Yet, few small businesses grow. One potential way of explaining why so many businesses do not grow is through the notion of 'barriers'. Previous studies on barriers typically identify and predict what kinds of barriers affect business growth, rather than attempt to explain how or why this is the case, if indeed it is the case at all. This thesis aims to elaborate on our understanding of barriers to small business growth. Two qualitative inductive interview-based studies were conducted in St. Petersburg Russia; the first was conducted in 2003, the second in 2005. Using semi-structured interviews in the second study (the main study), 27 owner-managers of small businesses in Russia were asked if they had intentions to grow the business, how they grew their businesses or intended to do so, and what, if anything, interfered with this process. The purpose of the study was two-fold: first, its purpose was to examine barriers from the perspective of individual owner-managers, with an emphasis on the meaning of barriers and the context in which they are perceived, and second to explore and examine how or the ways in which perceived barriers may influence owner-managers’ growth intentions and behaviours. Data were analysed using template analysis mainly, drawing on interpretive phenomenological analysis and matrix analysis. Based on the accounts of owner-managers, barriers were found to work in different ways to shape intentions to grow or not to grow, and as well to shape intention realization. How this occurred depended partly on owner-managers’ perceptions of the institutional environment. Findings suggest that the relationship between barriers and small business growth is complex. It is, nevertheless, a relationship which purports to be a fruitful area of study, one in which future research might further our understanding of small business growth from a continuing examination of barriers, particularly in relation to intentions, in relation to how meaningful barriers are perceived to be, and in relation to the context in which they are perceived.

Les clients de TS sont considérés comme un groupe à risque de VIH et aussi agiraient comme un « pont de transmission » entre les TS et les femmes de la population générale. En dépit de leurs comportements sexuels à risque, les clients de TS ont été rarement étudiés. En conséquence, les objectifs spécifiques de cette thèse étaient : 1) estimer la prévalence du VIH, de la syphilis, du VHS-2 (virus de l’herpès simplex et 2) des facteurs de risque associés chez les clients de TS en Haïti, 2) examiner les déterminants de l’intention d’utilisation du condom, et 3) estimer la prévalence des comportements de violence et ses conséquences. Pour ce faire, une enquête transversale a été effectuée en 2006 auprès de 378 clients fréquentant les milieux de prostitution de St-Marc et de Gonaïves, en Haïti. Un questionnaire structuré ainsi que des échantillons de sang séché sur papier filtre ont été utilisés pour la collecte de données comportementales et biologiques. Notre premier article a montré une prévalence élevée du VIH et des ITS chez les clients. Ces hommes avaient plusieurs partenaires sexuelles avec lesquelles l’utilisation du condom variait. Les clients qui avaient déjà consommé de la marijuana, pratiquaient le vaudou, avaient des antécédents d’ITS ou étaient infectés par le VHS-2, avaient plus de chances d’être positifs au VIH. Le fait d’habiter Gonaïves, de ne pas être protestant, d’être employé et d’avoir déjà essayé la marijuana était associé à l’infection à la syphilis. Tandis que les clients plus vieux, ceux résidants à Gonaïves ainsi que ceux pratiquant le vaudou étaient plus souvent infectés par le VHS-2. Dans notre second article, nous avons démontré que les normes subjectives, le contrôle comportemental perçu et les attitudes étaient des déterminants importants de l’intention d’utilisation du condom. Les clients qui avaient des antécédents d’ITS ou avaient utilisé le condom lors de la dernière relation sexuelle avec la TS étaient aussi plus susceptibles d’avoir l’intention d’en faire usage dans le futur. Les résultats du dernier article ont montré que la prévalence des comportements de violence envers les partenaires intimes était élevée. De plus, la violence émotionnelle et physique était associée à l’utilisation inconstante du condom avec les différentes partenaires sexuelles. En conclusion, cette étude suggère que les clients de TS agiraient comme un pont de transmission facilitant la propagation du VIH/ITS dans la population générale en Haïti et que la violence semblerait également jouer un rôle dans la transmission de ces infections. Nos résultats soulignent le besoin d’interventions en prévention du VIH et des ITS ciblant cette population vulnérable, incluant la problématique de la violence. / Male clients of FSWs are a high risk group for HIV and are considered a “bridge” of transmission between FSWs and women in the general population, through unprotected sex. In spite of their high risk behaviours, clients of FSWs have rarely been studied and they have been the target of few interventions. Therefore, the specific objectives of this thesis were to examine 1) estimate the prevalence of HIV, syphilis and HSV-2 (herpes simplex virus 2) infections and their associated risk factors among clients of FSWs in Haiti, to 2) examine the determinants of intention to condom use, and 3) estimate the prevalence of violence towards their intimate partners and its association with sexual risky behaviours. A cross-sectional survey was conducted among 378 clients visiting commercial sex sites in St-Marc and Gonaives, in Haiti. A structured questionnaire and dried blood spot samples were used to collect the behavioural and biological data. Our first research paper found that HIV/STI prevalence was remarkably high among clients of FSWs. These men had many sex partners and condom use differed, depending on the category of partner. Multivariate analysis indicated that clients who had tried marijuana, were practicing Voodoo, had a history of STI or were infected with HSV-2 were more often HIV-positive. Living in Gonaives, not being Protestant, being employed, and having tried marijuana were associated with syphilis infection. Older clients, residents of Gonaives and Voodoo practitioners were more likely to be infected with HSV-2. The second article revealed that subjective norms, perceived behavioural control and attitudes were predictors of intention to use condoms within this population. Clients having had a previous STI and who used condoms the last time they had sexual intercourse with a FSW were more likely to have the intention to use them in the future. The last article showed that prevalence of lifetime IPV was high among clients of FSWs. Moreover, history of emotional and physical IPV were strong predictors of inconsistent condom use with the different sexual partners. The fact that these abusive men are also more likely to be infected with an STI puts their sexual partners at high risk of infection. In summary, this study suggested that clients of FSWs likely act as a bridge population facilitating the spread of HIV/STI throughout the general population in Haiti and that violence seemed to play a role in the transmission. Our findings highlight the importance of STI/HIV prevention interventions addressing this vulnerable population, including gender-based violence.

Although South African consumers are reflecting increased green purchasing intentions, the factors that will lead to their intended behaviour to select green hotels have yet to be researched. Accordingly, the research proposes to explore the predictive ability of the Theory of Planned Behaviour (TPB) and then further modify and develop extended model structures surrounding the TPB, to identify and confirm an independent theoretical model that will effectively and comprehensively be able to predict South African consumers’ intended behaviour towards selecting green hotels. To answer the aim and objectives set, the research positioned itself within a non-experimental quantitative paradigm. An online questionnaire was distributed to South African consumers that stayed at a hotel at least once within a 12-month period. A total of 402 completed and error-free responses were used for statistical analysis. Descriptive statistical analysis was used to assess, derive and understand the demographic profile of the respondents and determine the respondent’s characteristics as South Africans who intend to stay at or visit hotels. Structural equation modelling (SEM) revealed that Azjen (1991)’s original TPB is a strong predictor of behavioural intention, indicating its applicability to the domain of South African consumers’ behavioural intention towards selecting green hotels. In addition, it was found that South African consumers’ intended behaviour towards selecting green hotels can statistically be best explained by expanding on the original TPB model to include emotive and non-cognitive predictor variables, namely anticipated regret (AR) and perceived moral obligation (PMO), as direct constructs to behavioural intention as well as by including environmental knowledge (EK) as a direct predictor variable to attitude (ATT). Furthermore, it found that the relationship between behavioural intention and perceived behavioural control (PBC) was the strongest and most significant, followed by subjective norm (SN), ATT, PMO and AR. Lastly, the findings revealed that PBC, ATT, SN, PMO and AR can all act as positive and highly significant intermediaries between EK and behavioural intention. The study contributed towards theory by identifying and assessing the psychographic factors that will best explain the consumer decision-making processes leading to behavioural intention in context to green hotel selection. The study further extends its contribution by adding value to environmental sustainable literature in context to an emerging economy, namely South Africa. Although South African consumers are reflecting increased green purchasing intentions, the psychological factors that will lead to the intended behaviour towards selecting green hotels have not received much attention in research. It was, therefore, important and theoretically valuable to not only investigate the predictive ability of the original TPB, but to also modify, develop and extend model variations surrounding the TPB to thoroughly explore the predictive ability for South African consumers’ intention to select green hotels. / Life and Consumer Sciences / M.

Includes bibliographical references (leaves 206-239) / The primary aim of the study was to develop a psychosocial assessment tool for determining willingness to participate in child-centred safety promotion interventions, specifically in a low-income community in South Africa. The secondary aim was to determine the factors associated with willingness to participate. The study employed a mixed methods approach to develop the measure, and included content validation, item writing and initial validation processes. Nominal Group Technique discussions were conducted with various role-players in the relevant communities to inform the development of the instrument, while participatory methodologies were utilised to conceptualise the instrument in relation to psycho-social factors associated with intervention participation, with these categorised according to core dimensions. A Delphi method utilising an expert panel reviewed items for relevance, difficulty and ambiguity, with items subsequently amended or removed. Item selection procedures were conducted on the English version of the instrument and these results were applied to the Afrikaans version. A pilot study was conducted as part of the initial validation in order to test the items and format the questionnaire. The instrument was then administered to Afrikaans speaking individuals in a community in the Western Cape. Iterative exploratory factor analysis was conducted at both the item and scale levels to select and reassign items and scales in order to determine the final composition of the questionnaire. The findings indicate that the instrument measures seven factors, namely incentives; priorities and community needs; perceived benefits; social approval; accessibility and values; altruistic capital; and community cohesion. These factors are explained in terms of the Process-Person-Context-Time model and the Theory of Planned Behaviour, considered within a participatory framework. The study findings indicate that the seven factors represent salient dimensions of the construct willingness to participate in interventions. The questionnaire and its subscales displayed acceptable to good reliability, with Cronbach’s α ranging from 0.55 to 0.80. Since willingness precedes actual participation, it is argued that insight into the factors that relate to willingness to participate provides an avenue for motivating actual participation. / Psychology / Ph.

Owing to the fact that entrepreneurship is widely considered to be a mechanism for reducing unemployment, the purpose of the study was to assess whether final-year Commerce students in the predominantly rural provinces, the Eastern Cape Province and the Limpopo Province, have the intention to start their own businesses.The study draws heavily from entrepreneurial intent models and focuses on the relationship between three key variables, namely, exposure to entrepreneurship education, awareness of entrepreneurial support and social capital to establish whether they are related to the intention of final-year Commerce studentsto start their own businesses. The literature review concentrated on entrepreneurial intent and entrepreneurial intent models; government entrepreneurial support initiatives in South Africa and in other countries and their role in the development of entrepreneurial intent, emergence of new ventures and the growth of small, medium and micro enterprises (SMMEs); entrepreneurship education and its role in enhancing entrepreneurial self-efficacy, entrepreneurial competencies and entrepreneurial intent;the influence of social capital on entrepreneurial intent and the different stages on the new venture life-cycle; and concludes with the link between entrepreneurship and the establishment of SMMEs. A survey was conducted among National Diploma (ND): Internal Auditing, Cost and Management Accounting and Financial information systems students (IAUD, CMA and FIS) (who had six months exposure to entrepreneurship education), ND: Entrepreneurship/Small Business Management (E/SBM) (who had three years exposure to entrepreneurship education) and ND: Management (without exposure to entrepreneurship education). The respondents for the study comprised 355 final year students of which 276 were from Walter Sisulu University in the Eastern Cape Province and 79 were from Tshwane University of Technology (Polokwane Campus) in the LimpopoProvince.Data was analysed using descriptive statistics and nonparametric statistics. The findings reveal that the majority of the respondents had the intention to start a business in the future.The entrepreneurial intent of the ND: E/SBM students was v stronger than the entrepreneurial intent of the ND: IAUD, CMA and FIS students and ND: Management students. Some significant relationships were found between entrepreneurial intent and the key variables of the study. / Business Management / D.Com. (Business Management)
