In hierdie skripsie word die verband tussen geslag en die bestuurstyl van die vroulike departementshoof in Afrikaansmedium sekondêre skole in die voormalige Noord-Transvaal- en Oos- Transvaalstreke ondersoek. Deur middel van 'n literatuurstudie is vasgestel wat die aard en wese van 'n bestuurstyl is. Bestuurstyle wat op enkele bestuursruite gebaseer is, asook bestuursbeginsels en leierskapstyle wat dien as bestuurstyle, is ondersoek. Dit is gevolg deur die determinante wat 'n bestuurstyl bepaal en die determinante wat geleë is in die onderwysbestuurder, die bestuursomgewing en in die personeel. Vervolgens is vasgestel hoe die bestuurstyl van die vroulike departementshoof lyk. 'n Oorsig is verkry oor die kenmerke van die vroulike departementshoof se bestuurstyl en daarna is die beplanningstyl, organiseringstyl, leidinggewingstyl en beheeruitoefeningstyl bespreek, asook die determinante van die vroulike departementshoof se bestuurstyl. 'n Empiriese ondersoek het die manlike en vroulike departementshoofde se selfpersepsie oor sy en haar bestuurstyl aan die lig gebring. Die enkele verskille in die response ten opsigte van die belangrikheid en die mate van gebruik van die verskillende bestuurstyle is vervolgens bespreek. Ten slotte is gevolgtrekkings gemaak oor die verband tussen geslag en die bestuurstyl van die vroulike departementshoof en enkele aanbevelings is gemaak. / Skripsie (MEd (Onderwysbestuur))--PU vir CHO, 1997

Introduction: From a legal point of view, gender-based discrimination is not condoned in the workplace. However, perceptions that such discrimination exists persist. Understanding the extent and nature of the phenomenon may contribute to the management thereof. Aim: The aim of this research was to report on the nature and level of workplace gender-based discrimination from the perspective of managers and employees, as well as by making use of objective measures. Method: Interviews were conducted with 75 managers focusing on the prevalence of gender-based discrimination in specific organisational processes. Furthermore, 145 managers and 1 740 employees completed questionnaires on this topic. Results: Managers reported flaws in all the organisational processes investigated. According to these managers, some processes showed a pro-female bias whilst others displayed a pro-male bias. More female than male employees reported discriminatory incidents at work, but both groups reported gender-based discrimination. Gender-based discrimination was the most prominent form of discrimination reported by women. Some female respondents reported pro-male and others pro-female discrimination. The same pattern applied to men. No statistically significant gender wage gap was found and the salaries of males and females were not differentially affected by qualifications, training, workplace experience or family responsibility. Managers and employees concurred that gender-based discrimination was the primary source of discrimination in the workplace, and they reported similarly on the consequences of this problem. Conclusions and recommendations: Managers are aware of discrimination in organisational processes. This awareness can be used to initiate programmes aimed at minimising discrimination. Both males and females are exposed to gender-based discrimination and they report similar consequences. This suggests that interventions should be directed at both groups. The different, and often opposing, reports provided by the male and female groups support the social identity theory and conceptions of group-serving bias. From the objective data it can be concluded that perceptions of being discriminated against are the result of psycho-social processes and not necessarily the result of justifiable biographical differences. / PhD (Business Administration), North-West University, Potchefstroom Campus, 2014

The importance of sport psychological skills (SPSs) is emphasised by numerous previous literature findings which show that the integration of SPSs with physical training leads to the development of adolescent sport participants and subsequently the enhancement of sport performance. A vast number of SPSs exist that could have an influence on a sport participant‟s performance. In order to efficiently develop the SPSs of sport participants it is important to acknowledge their specific individual needs. Furthermore, gender and the type of sport also play an integral role in participants‟ use of SPSs. The main purpose of the present study was firstly to determine which SPSs discriminate significantly between male and female adolescents in a South African context, and secondly to determine which SPSs discriminate significantly between individual and team adolescent sport participants in a South African context. A convenience sample of 211 grade 9 pupils (14-15 years of age) from six different primary schools, two from a high socio-economic background, Potchefstroom city area, and four from a low socio-economic background, Ikageng Township area, were included in the study. Participants completed the Physical Activity and Training Habit questionnaire as well as the Athletic Coping Skills Inventory-28 (ACSI-28) questionnaire under the supervision of a sport psychological consultant. The results from the first purpose of this study showed non-significant differences between the SPSs of the males and the females, where the males obtained slightly higher averages in seven of the eight psychological skill variables compared to the females. Only one SPS variable (freedom from worry), however, showed a statistically significant difference where the males obtained a higher average value than the females. The results from the second purpose showed that individual sport participants (ISPs) obtained higher mean scores in seven of the eight SPSs that were measured compared to team sport participants (TSPs). However, none of the subscale differences proved to be statistically significant, with a small practical significance. In conclusion it is clear that 14-15 year old adolescent sport participants showed similar tendencies regarding their SPSs than what was found in other studies. However, the differences in our study population have not yet reached significant levels and therefore the sport participants can be treated as a homogeneous group when psychological skills training (PST) programs are applied. The findings can contribute to a better understanding of the SPS use of sport participants from different genders, sporting codes and the development of PST programs of the different sport participants, which could assist coaches in the holistic development of adolescent sport participants. / MA (Sport Science), North-West University, Potchefstroom Campus, 2014

Self–regulation is a psychological skill that helps individuals to flexibly plan, execute and monitor their own behaviour. The key self–regulation processes include goal establishment, planning, the striving towards a goal and the revision thereof. Although it is clear that poor self–regulation is associated with psychopathology, the role gender plays is not well understood. Some differences between men and women suggest that gender may be a possible factor in self–regulation and the development of specific forms of psychopathology. The aim of this study was therefore to determine the relationship between self–regulation, psychopathology and gender amongst a group of university students. Participants consisted of an availability sample of 384 (284 female and 100 male) students at the NWU’s Potchefstroom Campus. Self–Regulation was measured with the Shortened Self–Regulation Questionnaire (SSRQ) of Carey, Neal and Collins (2004). In this study, the factor structure proposed by Potgieter and Botha (2009), based on a factor analysis of the SSRQ in the South–African context, was used. Psychopathology was measured with the General Health Questionnaire (GHQ) of Goldberg and Hiller (1979) as well as with a selfcompiled Alcohol and Eating Risk Questionnaire (AERQ). Data were captured and analysed using SAS. The two gender groups did not differ clearly regarding either self–regulation or psychopathology. This supports other studies that found no gender differences in specific selfregulation contexts, but contradicts a number of studies which indicate gender differences related to psychopathology. Interesting tendencies were noted regarding the association between self–regulation and psychopathology, independently for male and female students. Decision making and learning from mistakes, was found to be an important self–regulatory skill for both gender groups in this study, but with practical significance for male students only. For male students, differences in self–regulation were found regarding lower and higher risk for alcohol–related problems in contrast to female students, where differences were found only regarding risk for eating–related problems. It is more acceptable for males to misuse alcohol than it is for females in many societies, and this might explain why self–regulation is important for men regarding alcohol use. Current cultural values, attitudes, and practices and social norms, with particular emphasis on the sexualisation and objectification of women and their bodies, contribute to eating disorders and body image distress in females across their life span and specifically in college women. Thus, self–regulation becomes more important for females, as they are more vulnerable to eating–related problems. It was concluded that there is an important relationship between self–regulation and psychopathology, and in this study this relationship was found to be somehow different for male and female students. The results of this study have great implications both for further research and for clinical practice. / Thesis (M.A. (Clinical Psychology))--North-West University, Potchefstroom Campus, 2011.

Motivation Soluble urokinase plasminogen activator receptor (suPAR) is a known inflammatory marker, which is found in various body fluids. SuPAR reflects the immune and pro–inflammatory status of patients caused by HIV and tuberculosis, amongst others. However, recent studies have shown that suPAR is related to cardiovascular function. The cardiovascular health of the black South African population is a major health concern as this group suffers mostly from hypertension and stroke, leading to an alarming increase in cardiovascular morbidity and mortality. SuPAR may be able to contribute to early detection and prevention of cardiovascular diseases. No studies regarding the associations of suPAR with cardiovascular function have been investigated on black South Africans. Objectives To investigate suPAR as a possible marker of cardiovascular function in African and Caucasian men and women, by determining possible gender and ethnic–specific associations of suPAR with cardiovascular function. Methodology There were 207 African and 314 Caucasian men and women (aged 20–79 yrs.) included in this study. High–sensitivity C–reactive protein, glucose, lipids and creatinine were determined in fasting serum and suPAR was analyzed in plasma samples. Blood pressure was measured using the OMRON apparatus (HEM–747), with a 5–min rest interval between measurements. The Finometer device was used to determine the Windkessel compliance and the carotid dorsalis–pedis pulse wave velocity (PWV) was measured with the Complior (SP acquisition system) on the left side of each subject in the supine position. The means, adjusted means and proportions were compared between the groups by using independent t–tests, analysis of co–variance and the chi–square test, respectively. Associations were investigated between cardiovascular variables and suPAR using single and multiple regression analyses with either pulse wave velocity, systolic blood pressure, diastolic blood pressure or Windkessel compliance as dependent variable. Covariates included were age, body mass index, smoking, alcohol use, physical activity, glucose and high–density lipoprotein cholesterol. Results and conclusion SuPAR levels were significantly higher in Africans (P<0.001) compared to Caucasians. After adjusting for body mass index, suPAR increased significantly with age in all groups, except for African women. Moreover, the suPAR levels of African men and women were significantly higher than the Caucasians within each age quartile. While adjusting for age and body mass index, the cardiovascular profiles of the African and Caucasian men were less favourable compared to women, but suPAR levels were significantly higher in Caucasian women compared to men. In single regression, various measures of cardiovascular function correlated with suPAR in African men and Caucasian men and women. After adjusting for confounders the associations disappeared in Caucasian women, and remained nonsignificant in the African women. However, the association between PWV and suPAR remained significant in African men (B=0.19; P=0.030), while the association of systolic blood pressure (B=0.20; P=0.017), diastolic blood pressure (B=0.17; P=0.020) and Windkessel compliance (B=–0.14; P=0.004) with suPAR remained significant in Caucasian men. In conclusion, Africans presented higher suPAR levels compared to Caucasians, even when stratified by age. Gender specific associations indicated that suPAR was associated with arterial stiffness in African and Caucasian men only, therefore, indicating that suPAR could be a possible biomarker for predicting cardiovascular dysfunction. / Thesis (M.Sc.
