Studies in both children and adults indicate that waist circumference (WC), a measure of abdominal obesity is closely related to cardiovascular risk factors. The accurate identification of abdominally obese children in health screening programmes for early intervention is of importance. There are, however, concerns about using international definitions for screening purposes because in most instances these have been derived from Western populations and, therefore, may have limited usefulness to children in other parts of the world. When these cut–off points are used in developing countries, they ignore the fact that the growth patterns of children and burdens of disease vary between countries. Due to lack of population specific cut–off points for children in the developing world it may be tempting and convenient to use the same cut–off points as for children in developed countries, but such a practice runs the risk of exporting failure. Ideally, a screening tool should have both high sensitivity and specificity, and these are important considerations in choosing the definition for the detection of childhood abdominal obesity. High sensitivity is necessary to avoid failure of identifying obese children and high specificity of the screening tool ensures that non–obese children are not misclassified as obese, which may otherwise lead to unnecessary treatment and psychosocial implications of stigmatisation. Failure to identify the abdominally obese child may have more serious consequences than misclassification, since it results in an increase in adult morbidity and mortality. Therefore, the main aim of this thesis was to examine fat distribution patterns of black South African (SA) children in relation to health risk. The specific objectives were to: compare the body composition of black stunted and non–stunted children from two rural communities in South Africa; to describe and compare the age and sex specific WC percentile distribution for black SA children from different study populations and compare the WC percentile distribution with those for African–American (A–A) children and to assess the diagnostic accuracy of waist–to–height ratio (WHtR) as a marker for high blood pressure, a cardiovascular risk factor in SA children. Findings of this study demonstrated increased total adiposity in non–stunted children, but trends of increased central adiposity, measured as WHtR in stunted children. This warrants further investigation on this relationship among children older than 13 years in the African context where many children are stunted. The differences observed between the different data sets and between SA and A–A children suggest that nationally representative data should be used to develop age, sex and ethnic specific WC percentiles for this population. The results indicate clearly that the median WC of children from SA studies is smaller than those of A–A children, with a medium to large effect size for the difference. Results also suggest concern with respect to high WC values (> 80 cm) among some children. The recommended universal WHtR cut–off value of 0.5 for assessment of cardiovascular risk is not suitable for black SA children because it had low sensitivity in predicting high blood pressure. The absence of locally developed cut–off values for WC and WHtR for children warrants research due to the associations between being overweight and obese and disease outcomes. It is fundamental to detect risk at an early stage so that appropriate intervention can be initiated timeously. / Thesis (Ph.D. (Nutrition))--North-West University, Potchefstroom Campus, 2011.

There is widespread concern for the mental well–being of adolescents. Various studies have indicated the deleterious consequences of bullying for both victims and bullies, implying the serious need for interventions to lower the incidence of bullying in schools. Descriptive data must inform the development of intervention programmes. The present study aimed to provide such data and to add to existing research on bullying in South African schools. This quantitative study investigated bullying behaviour in a parallel–medium, multi–racial high school in the North–West Province. The specific research aims were to examine the total incidence of bullying experiences and, specifically, frequency levels of being bullied according to age group and race group. Furthermore, gender differences in frequency levels of individual and group bullying, as well as gender–specific frequency levels of use of direct and indirect bullying tactics were examined. A one–shot cross–sectional survey design was employed. A randomly selected representative sample of 635 learners, comprising 274 boys and 361 girls, completed a self–report survey instrument, the Peer Relation Questionnaire (Neser, Ladikos and Prinsloo 2004), with regard to their bullying experiences. The Statistical Package for the Social Sciences (SPSS) was used to calculate frequencies, cross–tabulations and chi–square statistical tests. Results indicated that 52% of participants reported to have been the victims of bullying. A significant difference in distribution of bullying frequency was indicated for race groups, but not for age groups. Black and coloured learners in this school experienced a higher frequency of bullying than white learners, which indicates that racial dynamics has an important impact on bullying behaviour in this school. Bullying frequency in this high school is not significantly lower in senior secondary learners (learners 16 years and older) than in junior secondary learners (learners between 13 and 15 years), as was predicted by literature. In terms of gender differences, boys in this school were found to bully significantly more than girls. Furthermore, group bullying was found to be more prevalent than individual bullying in both genders. In this school boys and surprisingly girls too were shown to favour direct verbal bullying tactics (unpleasant teasing) and direct physical bullying tactics (hitting, kicking or pushing). This finding is a cause for concern as it is contradicted by literature which describes girls as preferring indirect bullying tactics (isolating the victim or threatening harm) to direct physical tactics, indicating that girls in this school use higher levels of physical aggression in bullying than the findings of other literature. The found high incidence levels of being bullied and bullying behaviour trends indicate a need for an anti–bullying intervention in this school, which includes learners of all age and race groups. The study's findings imply that such an intervention should include a focus on bullying of black and coloured learners and address racial dynamics in bullying. Furthermore intervention should address group and individual bullying, as well as the use of direct bullying tactics among both boys and girls, particularly direct physical tactics. Altough these findings are not generalisable to other South African schools, the need for further South African research to investigate unique trends in bullying behaviour is stressed. / Thesis (M.Sc.

Various scales have previously been developed to measure coping strategies (Taylor & Stanton, 2007; Devonport & Lane, 2006; Stapelberg, 1999) or self–efficacy (Carroll et al., 2005; Chen et al., 2001; Tipton & Worthington, 1984); and some of them have been validated in a South African context, but the validation of a coping self–efficacy scale as a single measurement has not been conducted in an African context. Therefore, the aim of this study was to validate Chesney et al.’s 2006 Coping Self–Efficacy Scale (CSE) in an African context. A multicultural convenience sample of 2 214 South African adolescents and adults, including both male and female participants, participated in this study. Measuring instruments such as the Coping Self–Efficacy Scale (CSE) (Chesney, Neilands, Chambers, Taylor & Folkman, 2006), the Mental Health Continuum - Short Form for adults (MHC–SF) (Keyes et al., 2008), the New General Self–Efficacy Scale (NGSE) (Chen, Gully & Eden, 2001; 2004), the Fortitude Questionnaire (FORQ) (Pretorius, 1998), the Patient Health Questionnaire: Depression Symptoms (PHQ–9) (Kroenke, Spitzer & Williams, 2001) and the General Health Questionnaire (GHQ) (Goldberg & Hillier, 1979) were used in this study. Criterion–related validity of the CSE was established. Construct validity was determined by conducting confirmatory and exploratory factor analyses as well as SEM on the CSE. Results indicated a Cronbach alpha reliability coefficient of 0.87 and satisfactory inter–item correlations ranging from 0.19–0.21. Criterion–related validity was satisfactory. Confirmatory analysis indicated a good fit and exploratory factor analysis confirmed the three major factors similar to Chesney et al.’s (2006) findings. Construct validity was further supported by SEM analysis, which confirmed the three–factor structure. The CSE can be viewed as reliable and valid for use in further research in the African context. Future studies should validate this scale in various population groups, with translated versions of the scale and with randomly selected groups. / Thesis (M.A. (Research Psychology))--North-West University, Potchefstroom Campus, 2011.

Motivation: Recently, with urbanisation becoming an increasing trend, the African population have been introduced to the westernised lifestyle. This contributed to severe health implications and a rapid increase in cardiovascular morbidity and mortality in the African population. In South Africa and other sub–Saharan African countries, the prevalence of cardiovascular disease is increasing rapidly. The African population is thus regarded as a high risk group, and we deem it necessary and important to investigate additional possible cardiovascular risk markers in the attempt to improve the diagnosis of cardiovascular diseases and the treatment thereof. We investigate double product as a possible cardiovascular risk marker in African and Caucasian men from South Africa. Recent studies have suggested that increased double product values might be an independent predictor of cardiovascular morbidity and mortality. However, investigations on double product and endorgan damage are limited in this population group. The strength of associations between double product and various measurements of end–organ damage, including intima–media thickness, left ventricular hypertrophy and albumin–to–creatinine ratio, are compared with the associations between the more traditional risk factor, systolic blood pressure, and the measurements of end–organ damage. Aim: The aim of this study is to investigate the usability of double product as a possible cardiovascular risk marker in African and Caucasian men from South Africa. Methodology: The manuscript presented in Chapter 3 made use of the cross–sectional SABPA (Sympathetic Activity and Ambulatory Blood Pressure in Africans) study, where 101 urbanised African and 101 Caucasian male school teachers from the North West Province of South Africa were recruited. Anthropometric measurements were taken in triplicate using standard methods. The cardiovascular measurements included 24–hour ambulatory blood pressure and electrocardiogram measurements. Double products were calculated as the product of 24–hour, daytime and night–time mean systolic blood pressure and mean heart rate values. The carotid intima–media thickness was also obtained following the prescribed protocols. A registered nurse collected blood samples and the biochemical measurements were performed by independent laboratories, blinded to the subject’s cardiovascular profile. Means and proportions were compared by standard t–tests and the x2 –tests, respectively. The association between markers of end–organ damage and double product were investigated using single, partial and multiple regression analyses. All p–values <= 0.05 were deemed significant. Results and conclusions: Results from this study showed that Africans displayed significantly higher systolic blood pressure values, heart rate values and subsequent double product values compared to the Caucasians. Despite these significant differences, double product only showed borderline significant correlations with the markers of end–organ damage in African men, while no correlations were evident in Caucasian men. In African men, systolic blood pressure displayed stronger and significant correlations with intimamedia thickness, left ventricular hypertrophy, and albumin–to–creatinine ratio than double product. These findings suggest that double product may not be a good marker of increased risk for end–organ damage and subsequent cardiovascular–related mortality. / Thesis (M.Sc.

Introduction: The importance of brands and the competition between private and national brands in different food categories increased in recent years. According to literature, except for packaging and price, there is virtually no difference between the contents of food products in the majority of private and national brands. Private brands are usually cheaper than national brands. Previous research indicated consumers’ preferences for private and national brand food products to differ between various products and in different regions. Objective: The aim of this study was thus to determine the relationship between consumers’ brand preferences for different food products, in relation to their demographics and psychographics in a South African context. Setting: A mall intercept, interviewer administered questionnaire was used as a quantitative method in this study in Potchefstroom in a South African context. Consumers’ preferences for private and national brand food products in different product categories were explored, using preference, psychographics and demographical questions simultaneously. Results: Respondents in this study preferred to purchase national brands in all products categories except for cooking oil. Considering eight psychographic factors that were extracted by exploratory factor analysis, two factors could be associated with positive reactions, while neutral reactions were evident for six factors. Respondents being indecisive on the majority of factors could be due to the fact that national brands were preferred for most products by respondents in the present study. Conclusions: Although brand preference depended on demographics and psychographics in previous research, the present study did not find significant relationships with psychographics when different products were used. Although a combination of demographic factors (mainly gender, education level, home language and employment status) could be useful in determining brand preference when used with specific products, home language and education level seem to be the most important factors. Therefore, brand preference depended on specific demographics for each product, while psychographic factors did not play a significant role. This implied that brand preference research should be product and region specific using specific demographic variables. / Thesis (M.

The purpose of the research was to explore the experiences of educators regarding the training for the implementation of inclusive education in a Full Service school. A qualitative research design was chosen, using a case study. Three methods of gathering data were used, namely individual interviews, focus group interviews and observations. The study was conducted in a primary schools in the North West province that was converted into a fullservice school in 2008. The findings indicated that educators demonstrated misunderstanding of the Screening, Identification, Assessment and Support strategy. The misunderstanding can be ascribed to the kind of training educators received. The training lacked in–depth content and practical demonstration. Recommendations on the content and the dynamics of the training process are made. The overarching recommendation on the dynamics of the training indicated that the training should be revisited for improved methods of training. / Thesis (M.Sc.

SMEs are important for a country's economy, since they provide benefits such as entrepreneurship, employment, exports and productivity to an economy. An economy that shows substantial growth is usually characterised by a strong and growing SME sector. South African SMEs need to grow to create jobs and benefit the South African economy. One way that SMEs can become strong and grow is through internationalisation. Firms are internationalising faster than ever before (because of advances in telecommunications and transportation) and internationalisation theories that can provide practical guidance to firms are more important today than in the past. The motivation of the study was to identify the areas that the South African government can develop in order to transform the economy into an emerging economy that can be on par with the BRIC countries. SMEs make up a large part of the BRICS economies and they grow through exports. In order to be on par with the BRIC countries, it is necessary to compare South African exporting and non–exporting SMEs with those in the BRIC countries. This will help to identify areas where South African SMEs' competitiveness can improve, especially in South–South trade. The competitiveness of SMEs involved in exporting also tends to improve. Therefore, if SMEs' competitiveness improves, it may be less risky for them to internationalise, which can lead to them being able to export more successfully, grow as a result of exporting and so contribute to employment. The primary objective of the study was to make a comparison between the characteristics of internationalising SMEs in South Africa and the BRICS countries. Data was obtained from the World Bank Enterprise surveys to conduct an empirical analysis on firms in the BRICS countries. The empirical analysis provided descriptive statistics on internationalising firms and SMEs in the BRICS countries. The descriptive statistics was used to make a comparison between the characteristics of internationalising SMEs in the BRICS countries (primary objective). South Africa has the highest percentage of exporting SMEs, followed by India, Brazil, Russia and China. China had the most exporting SMEs with an internationally recognised certification. The top managers of Chinese exporting SMEs are higher educated than those in India and South Africa. SMEs in Russia internationalise at by far the youngest age and thus are likely to follow the rapid international theories. South African SMEs had the highest average age, meaning that SMEs first are established in the domestic market before they internationalise through exports. Internationalisation has become an important strategy for firms that want to achieve further growth, but it is also very tough to survive in the international market. An interesting finding of this study was that the two obstacles South Africa had in the top 5 namely, crime, theft and disorder, and electricity were not a top 5 obstacle for any of the other BRIC countries. Another objective of the study was to empirically determine the characteristics of internationalising SMEs in South Africa. SMEs in South Africa are more likely to internationalise through exports if they are, amongst others, older (longer established in the domestic market), have a larger market share in the South African domestic market, have a top manager with experience and a higher education level (some university training minimum) and have less competitors in the South African domestic market. The comparison between the characteristics of internationalising SMEs of the BRICS countries provided several lessons for the South African government and exporting SMEs. The areas or aspects that the South African government need to develop in order to transform the economy into an emerging economy that can compete with the BRIC countries, include assisting SMEs in exporting at an earlier age, improving the education levels of top managers in SMEs, increasing the national market share of SMEs and lessening, or even eliminating, obstacles like crime, theft and disorder as well as electricity. These aspects, together with the characteristics of internationalising SMEs in South Africa, are vital to improve SME competitiveness. Therefore, if SMEs' competitiveness improves, then it may be less risky for them to internationalise, which can lead to them being able to export more successfully, grow as a result of exporting and so contribute to employment. / Thesis (M.Com.

The financial crisis that struck financial markets in 2008 was devastating for the global economy. The impact continues to be felt in the market - most recently in sovereign defaults. 1 There are many questions as to the origin of the crisis and how the same events may be prevented in the future. This dissertation explores two financial instruments: securitisation and credit default swaps (CDSs) and attempts to establish the role they played in the financial crisis. To fully understand the events that unfolded before and during the crisis, a sound theoretical understanding of these instruments is required. This understanding is important to discern the future of stable financial markets and to gain insight into some of the potential risks faced by financial markets. The South African perspective regarding securitisation, CDSs and the global financial crisis is an important field of study. The impact of the crisis on South Africa will be explored in this dissertation, as well as, the effect of the crisis on South Africa's securitisation market (which has proved healthy and robust over the first part of the new millennium despite the global slowdown of these instruments) and the CDS market. A key goal of this work is to establish whether or not CDSs have been used in South Africa to hedge the credit risk component of bonds linked to asset–backed securities (ABSs). This will provide an indication of the maturity of the South African credit risk transfer (CRT) market and how South Africa compares to more developed financial markets regarding complexity, regulation, sophistication and market sentiment. Through the exploration and understanding of these concepts, the efficacy of emerging economies to adapt to globalisation, and how welcome financial innovation has proved to be in emerging markets will be addressed. / Thesis (M.Com.
