Subjekvorming deur literatuuronderrig aan universiteite in Suid-Afrika sedert 1994 / Gerda Dullaart

Dullaart, Anna Gertruida January 2002 (has links)
Hierdie studie ondersoek die beroepsgeleenthede vir literatuurgraduandi in postapartheid Suid-Afrika. Die subjekvorming van literatuurstudente en -dosente word ondersoek deur ideologie-kritiese analises van akademiese en politieke diskoers. Uit die analises blyk 'n kloof tussen die wêreld van werk en die akademiese ivoortoring, tussen brood en boeke. Dit blyk dat diskoers uit die beroepswêreld nie die ivoortoring deurdring en die literêr-akademiese diskoers insemineer nie. Die kloof word toegeskryf aan akademiese magsverhoudings wat subjekvorming reguleer, en aan die ideologiese prosesse waarmee literatore gemarginaliseer word in die "regte wêreld". As 'n eerste stap ondersoek die studie die akademie as 'n kerngesin en pas Luce lrigaray se feministiese psigoanalise toe op die verhouding tussen dosente en studente. Die gevolgtrekking is dat literatuurdosente die ekonomiese potensiaal van literatuurgraduandi uitsluit, om so hulle eie subjek nisse as houers van simboliese kapitaal vol te staan. Subjekvorming is 'n beweging vanaf die (akademiese) kerngesin in die wyer wêreld in. Daarom ondersoek die studie in 'n tweede stap hoe literatuurgraduandi se subjekvorming plaasvind in die drie ideologiese staatsapparate (ISA's) van Althusser (ekonomie, onderwys en politiek). Hieruit spruit insigte oor identiteitsvorming in die spanningsvelde tussen kapitalisme, postkolonialisme, neokolonialisasie en globalisasie. Dit blyk dat literatuurgraduandi goed kan vaar in ruwe nuwe ekonomiese terreine soos ontwikkelingswerk, omgewingsonderwys, kennisbestuur en elektroniese joernalistiek. Hulle is egter nie bewus van hierdie beroepsgeleenthede nie, as gevolg van die kloof tussen brood en boeke. Om die kloof te oorbrug, beveel die studie in 'n derde stap aan dat literatuuronderrigdoelstellings eksplisiet vertaal moet word tot beroepsvaardighede. Om literatuurdosente te help om doelstellings te formuleer wat begeerlik is op die arbeidsmark, is 'n interaktiewe rekenaarprogram ontwikkel as deel van die studie. Dit is beskikbaar op die internet by http://www.smartt.co.za/wizz/wizz.htm Literatuurdosente kan die kloof ook oorbrug deur studente te bemagtig deur middel van die dialogiese onderrigmetode, soos ontwikkel deur bevrydinspedagoog Paulo Freire. Verder kan dosente die magsverhoudings van die akademie dekonstrueer en as radikale dosent onderrig bied in dissent en diskursiewe vaardighede. Dissent en diskursiewe vaardighede is ook kosbaar op die arbeidsmark, en aktiveer literatuurdosente en -studente se vryheid en verantwoordelikheid om hulle eie subjek nisse te bepaal en etiese plekke in te neem as kritiese en revolusionêre intellektueles. / Thesis (Ph.D. (Applied Language and Literary Studies))--Potchefstroom University for Christian Higher Education, 2002

Determinants of infant mortality level in chosen African countries / Determinanty úrovně kojenecké úmrtnosti ve vybraných afrických zemích

Morkusová, Andrea January 2015 (has links)
The aim of the diploma thesis is to analyse which determinants have an impact on infant mortality in West and East Africa for a year 2012 based on correlation and regression analysis. Representative countries Ghana, Nigeria and Senegal for West Africa and Kenya, Tanzania and Uganda for East Africa, were chosen. From the gained results and information, recommendation for possible better future development of infant mortality is concluded as the outcome of the diploma thesis aim. On base of data analysis, one variable, which influences a development of infant mortality, was not identified, but it can be assumed that a complex of variables affects the infant mortality. In this line with final findings, current strategy of development aid is focused primarily on local activities more than just on financial help.

Social media and mobile money adoption: comparative evidence from South Africa and Zimbabwe

Munongo, Shallone 06 1900 (has links)
Abstract in English, Afrikaans and Zulu / The study investigated the effects of social media on mobile money adoption in South Africa and Zimbabwe. The main gap identified in empirical literature is the omission of social media use in technology adoption models and social networking theories. While some theories acknowledge the role of social influences in technology adoption, the social interactions considered therein are not mediated through the internet as is social media. Furthermore, no empirical study has to date focused on how social media influences mobile money technology adoption. Thus, this study deviates from the offline social network analysis approach which is restricted to the neighbourhood effects, physical contact, cell phone calls and text messages where information on mobile money technology is disseminated to an individual’s limited social circle. The secondary data used for the study were obtained from individual responses in the cross-sectional FinScope consumer surveys South Africa 2015 and Zimbabwe 2014 which were conducted and reported by FinMark Trust (2015; 2014). The study employed the binary logistic regression model to estimate the nature of effect. The results of the study indicated that use of social media had a positive and statistically significant impact on mobile money adoption in both South Africa and Zimbabwe. The results also revealed that despite there being a lower internet penetration and social media usage rate in Zimbabwe than South Africa, the use of social media in the former led to a higher rate of mobile money adoption. The study also established that mere use of social media and availability of mobile money technology did not translate to a high adoption rate; instead, availability had to be matched by a demand for the financial services. Additionally, the study found that the interaction of mobile money adoption and use of social media increased the overall mobile money adoption in both countries. The study recommended the implementation of collective policies that increase internet penetration to facilitate increased use of social media platforms and promote mobile money adoption to foster improved financial inclusion in developing countries. / Hierdie studie het die gevolge van sosiale media op die ingebruikneming van mobiele geld in Suid-Afrika en Zimbabwe ondersoek. Die belangrikste leemte wat in empiriese literatuur geïdentifiseer is, is die weglating van die gebruik van sosiale media in tegnologieaanvaardingsmodelle en sosialenetwerkvorming-teorieë. Hoewel sommige teorieë (teorie van beredeneerde handeling; teorie van beplande gedrag; diffusie van innovasie) die rol van sosiale invloede op tegnologieaanvaarding erken, word die sosiale interaksies wat daarin oorweeg word nie deur middel van die internet bemiddel nie, soos wel in die geval van sosiale media. Boonop het geen empiriese studie tot op hede gefokus op hoe sosiale media die ingebruikneming van mobielegeld-tegnologie beïnvloed nie. Hierdie studie wyk dus af van die niegekoppelde sosialenetwerkontleding-benadering, wat beperk is tot die omgewingsgevolge, fisieke kontak, selfoonoproepe en teksboodskappe, waar inligting oor mobielegeld-tegnologie aan ʼn individu se beperkte sosiale kring versprei word. Die sekondêre data wat vir die studie gebruik is, is verkry uit afsonderlike response in die deursnee- FinScope-verbruikersopnames (Suid-Afrika 2015 en Zimbabwe 2014), wat onderneem en bekendgemaak is deur FinMark Trust (2015; 2014). Die studie maak gebruik van die binêre logistiese regressiemodel om die aard van effek te skat. Studiebevindings dui daarop dat die gebruik van sosiale media ’n positiewe en statisties beduidende uitwerking op die ingebruikneming van mobiele geld in sowel Suid-Afrika as Zimbabwe het. Die resultate wys ook dat, ondanks ’n laer internetpenetrasie en sosialemedia-gebruikskoers in Zimbabwe, die gebruik van sosiale media in Zimbabwe tot ’n hoër koers van ingebruikneming van mobiele geld in dié land as in Suid-Afrika tot gevolg het. Daar word verder waargeneem dat die blote gebruik van sosiale media en die beskikbaarheid van mobielegeld-tegnologie nie geredelik omgesit kan word in ’n hoë ingebruiknemingskoers nie; beskikbaarheid moet met ’n vraag na die finansiële dienste gepaard gaan. Daarbenewens toon die studie dat die interaksie tussen mobielegeld-ingebruikneming en die gebruik van sosiale media die oorkoepelende ingebruikneming van mobiele geld in albei lande versterk. Die studie beveel die implementering van beleide aan wat internetpenetrasie verhoog om wydverspreide gebruik van sosiale media te fasiliteer, wat op sy beurt die ingebruikneming van mobiele geld sal bevorder, wat finansiële insluiting sal bevorder. / Ucwaningo luphenyisise imiphumela ye-social media ekwamukelweni kwe-mobile money eNingizimu Afrika naseZimbabwe. Igebe elikhulu eliphawuliwe kwimibhalo yobufakazi ukweqiwa kokussetshenziswa kwe-social media ekwamukelweni kwama-technology adoption models kanye namathiyori e-social networking. Kodwa amanye amathiyori (i-theory of reasoned action; i-theory of planned behaviour; i-diffusion of innovation) amukela indima yemithelela ye-social influences ekwamukelweni kwetheknoloji, ngokusebenzisana kwama-social interactions abonelelwe lapha, awaxhunyaniswa nge-inthanethi, njenge-social media. Kanti-ke futhi okunye, akukho bufakazi bocwaningo kuze kubemanje obugxile kwindlela i-social media enomthelela ngayo kwi-mobile money technology adoption. Ngakho-ke, lolu cwaningo luyehluka kwizinqubo ze-offline social network analysis approach, enezihibe kwimiphumela esondelene nayo, ukuxhumana ngokubamba, ukushayelana izingcingo nge-cellphone, kanye nemilayezo ebhaliwe, lapho ulwazi kwi-mobile money technology lusatshalaliswa kumuntu ngamunye nalabo asondelene nabo. I-secondary data esetshenzisiwe kucwaningo itholakale kwizimpendulo zabantu ngamunye kwi-cross-sectional FinScope consumer surveys (iNingizimu Afrika 2015 kanye neZimbabwe 2014), olwenziwa nokubikwa nge-FinMark Trust (2015:2014). Ucwaningo lusebenzisa i-binary logistic regression model ukulinganisa inhlobo yomphumela. Imiphumela yocwaningo ikhombisa ukuthi i-social media inomphumela omuhle futhi ngomphumela wezibalo ezibalulekile ekwamukelweni kwe-mobile money okwamukelwe kuwo womabili amazwe iNingizimu Afrika kanye neZimbabwe. Imiphumela ikhombise nokuthi, ngisho noma i-inthanethi ingakangeneleli kangako kwezinye izindawo, kodwa izinga lokusetshenziswa kwe-social media eZimbabwe kungaphezulu kuneNingizimu Afrika, ukusetshenziswa eZimbabwe kuhola phambili ngezinga eliphezulu ekwamukelweni kwe-mobile money kunaseNingizimu Afrika. Kanti futhi kuphawulwa ukuthi ukusetshenziswa kwe-social media kanye nokutholakala kwe-mobile money technology, akuhambelani ngezinga lokwamukelwa kakhulu; ukutholakala kumele kuhambelane nesidingeko samasevisi ezezimali. Nangaphezu kwalokho, ucwaningo lukhombisa ukuthi ukusebenzisana kokwamukelwa kwe-mobile money nokusetshenziswa kwe-social media kuphakamisa ukwamukelwa kakhulu kwe-mobile money kuwo womabili amazwe. Ucwaningo luncoma ukuthi ukwamukelwa kwemigomo enyusa ukungenelela kakhulu kwe-inthanethi ukulekelela ukusetshenziswa kakhulu kwe-social media, kanti futhi lokhu okuzophakamisa kakhulu ukwamukelwa kwe-mobile money okusiza ukubandakanya wonke kwezezimali. / Business Management / D.

The role of personal remittances in financial sector development : evidence for Africa

Kumire, Margaret 06 1900 (has links)
The study investigated the impact of remittances on financial development in Africa using the dynamic generalised methods of moments (GMM) and other panel data analysis methods with data from 2003 to 2015. Using the same econometric estimation methods, the study also explored the influence of the complementarity between remittances and economic growth on financial development in Africa. Literature on the relationship between remittances and financial development is mixed, inconclusive and indecisive. The desire to contribute towards literature on the influence of remittances on financial development in the African context prompted this study. In Africa, personal remittances had an insignificant positive impact on financial development across all the econometric estimation approaches in all the four models, in line with some empirical studies on the subject matter. African countries are urged therefore to avoid wasting their time developing and implementing remittances, foreign aid and human capital development enhancement policies as a way of spearheading financial development. Using both broad money (as % of GDP) and domestic private credit ratio as measures of financial development, the interaction between remittances and economic growth was found to have a non-significant negative effect on financial development in Africa. The policy implication is that Africa needs to avoid over relying on economic growth as a channel through which financial development can happen / Die studie het die impak van betalings op finansiële ontwikkeling in Afrika ondersoek – deur middel van die dinamiese veralgemeende momentemetode (GMM) en ander metodes van paneeldata-ontleding, met data van 2003 tot 2015. Dieselfde ekonometriese beramingsmetodes is ook ingespan om die invloed van die komplementariteite tussen betalings en ekonomiese groei op finansiële ontwikkeling in Afrika te ondersoek. Die literatuur oor die verwantskap tussen betalings en finansiële ontwikkeling is gemeng, onoortuigend en vaag. Die begeerte om tot die literatuur oor die invloed van betalings op finansiële ontwikkeling in die Afrika-konteks by te dra, het tot hierdie studie aanleiding gegee. In Afrika het persoonlike betalings ʼn onbeduidende positiewe impak op finansiële ontwikkeling in al die benaderings tot ekonometriese beraming in al vier modelle gehad, wat strook met sommige empiriese studies oor die onderwerp. Afrika-lande word dus gemaan om nie hul tyd te mors met die ontwikkeling en implementering van betalings en buitelandse hulp en beleide om mensekapitaalontwikkeling te verbeter as ʼn manier om finansiële ontwikkeling te lei nie. Daar is bevind dat sowel breë geldvoorraad (as ʼn persentasie van BBP) en die binnelandse private kredietverhouding as maatstawwe van finansiële ontwikkeling, die wisselwerking tussen betalings, en ekonomiese groei ʼn nie-beduidende negatiewe uitwerking op finansiële ontwikkeling in Afrika het. Die beleidsimplikasie is dat Afrika moet waak teen oorafhanklikheid van ekonomiese groei as ʼn kanaal waardeur finansiële ontwikkeling kan plaasvind. / Ucwaningo beluphenya umthelela wezimali ezibhadalwayo mayelana nokuthuthukiswa komkhakha wezezimali e-Afrika ngokusebenzisa izindlela ezifanayo zezikhathi (GMM) kanye nezinye izindlela zokuhlaziywa idatha yephaneli ngokusebenzisa idatha yonyaka ka 2003 ukufikela ku 2015. Ngokusebenzisa izindlela ezifanayo zohlelo lokulinganisa isimo somnotho (econometric estimation), ucwaningo futhi luye lwahlola umthelela wousebenzisana okuphakathi kwezimali ezibhadalwayo kanye nokuhluma komnotho mayelana nokuthuthukiswa ngezimali e-Afrika. Umbhalo wobuciko mayelana nobudlelwano phakathi kwezimali ezibhadalwayo kanye nokuthuthukiswa kwezinhlaka zezimali uxutshwe ndawonye, awunaso isiphetho futhi awukwazi ukuthatha izinqumo. Isidingo sokufaka igalelo embhalweni wobuciko mayelana nomthelela wezimali ezibhadalwayo kwihlelo lokuthuthukiswa kwezimali ngaphansi kwesizinda sase-Afrika, ykho okuphembelele ukuthi kube nalolu cwaningo. E-Afrika, izimali ezibhadalwa abantu ziye zaba nomthelela omuhle kwintuthuko yezimali kuzo zonke izindlela zokulinganisa izinga lentuthuko yezomnotho kuwo wonke amamodeli amane, ngokuhambisana nezinye izifundo zocwaningo oluphathekayo lwalesi sifundo. Ngalokho-ke amazwe ase-Afrika ayanxenxwa ukuthi agweme ukumosha isikhathi sawo athuthukisana futhi asebenzisa uhlelo lokuthumela izimali futhi agweme ukuqinisa imigomo yoncedo oluvela emazweni angaphandle kanye nokuthuthukisa abantu ngokwamakhono omsebenzi, njengento yokuhlahla indlela yohlelo lokuthuthukiswa kwezimali. Ukusethenziswa kokubili imali ebanzi (njengephesenti le-GDP) kanye njengesilinganiso sesikweletu, phecelezi-domestic private credit ratio sisebenza njengesilinganiso sezinga lokutthuthuka ngokwezimali, ukusebenzisana phakathi kwezimali ezibhadalwayo kanye nokuhluma komnotho kutholakele ukuthi kube nomthelela ongabalulekile omubi phezu kwezinga lentuthuko yezimali e-Afrika. Ngokomgomo lokhu kuchaza ukuthi i-Afrika idinga ukuthi igweme ukwencika kakhulu ukusebenzisa uhlelo lokuthuthukiswa komnotho njengomgudu lapho kungathuthukiswa komnotho. / Financial Accounting / M.

Waste management behaviour : a case study of school children in Mpumalanga, South Africa / Ignatius Michael van Niekerk

Van Niekerk, Ignatius Michael January 2014 (has links)
This study examined the level of awareness, knowledge and practices of primary and secondary schools students with regard to waste management. Only a limited number of studies were found to evaluate school student’s awareness, knowledge and practice of waste management in South Africa. Literature was reviewed dealing with waste management awareness, knowledge and practices of school students and discussed at the hand of the principles, objectives and targets of the South African Government towards waste and waste management. Using a structured, self-administered questionnaire, a total of 815 students were surveyed from four primary schools and three secondary schools from the Embalenhle and Secunda area Govan Mbeki Municipality, Mpumalanga South Africa. The data were analysed by the use of descriptive statistics including frequency count, percentage, mean and standard deviation. Other analyses employed included two-way frequency tables with Pearson Chisquare test, Phi coefficient, in order to determine the significant relationship between students’ socio-demographic variables. The study showed that the students were obviously aware of concerns with waste and waste management practices in their schools and local environment. It was also apparent the school students had an acute awareness that poor waste management would have a negative impact on the country as well as on them as the individual. This prominent awareness was however not evident in the students’ waste management practices. Good waste management practices activities were minimal at both the school and home environment. Since school students are seen as one of the key agent of change to work towards a more sustainable future, they should be engaged as young as possible and given a quality array of continuous learning to improve their knowledge on environmental problems such as poor waste management. Improved knowledge would contribute to improved environmental awareness and a pro-environmental attitude. The critical recommendations of the study are that the South African Government will have to intensify the research to better understand the needs of children to environmental matters such as waste management. / M.

Cancer patients' and health care professionals' perceptions and experiences of cancer treatment and care in South Africa / Mariska Venter

Venter, Mariska January 2014 (has links)
Cancer is a potentially life-threatening disease, which affects millions of people worldwide. It is multifaceted in nature and can lead to impairment in a person‟s physical, social and emotional functioning (Beatty, Oxlad, Koczwara, & Wade, 2008). Multidimensional treatment, with highly specialised professionals, equipment and services is thus needed for the effective treatment thereof (Mathews, West, & Buehler, 2009). Patients treated within the private and public healthcare sectors of South Africa have vastly differing treatment experiences. Only about 20% of the South African population has access to and can afford treatment within the private healthcare sector (Somdyala, Bradshaw, Gelderblom, & Parkin, 2010). While private sector patients have access to information, social workers and support groups, those in the public sector face life-threatening waiting times and a lack of empathy by public sector staff, weighed down by patient numbers and a lack of resources (Pillay 2002; Bateman, 2011). A study previously conducted by the researchers highlighted cancer patients‟ perceptions and experiences of treatment as being one of the most prominent themes influencing patients‟ overall cancer experience (Venter, Venter, Botha, & Strydom, 2008). This, coupled with the fact that the majority of research studies previously conducted in South Africa generally focused on the biomedical aspects of cancer (Albrecht, 2009), make exploring patients and healthcare professionals‟ perceptions and experiences of cancer treatment in a South African context potentially valuable. The thesis consists of three sub-studies reported in three manuscripts. The aim of the first article was to provide a narrative literature review exploring cancer survivorship and management in the South African context by scrutinising research previously conducted on cancer treatment. The aim of the second and the third article was to explore patients and healthcare professionals‟ perceptions and experiences of cancer treatment in the private and public healthcare sectors in the Eastern Cape, South Africa. A 100 participants were purposively sampled from a government-funded hospital (n = 30 patients; n = 22 healthcare professionals) and a private treatment facility (n = 30 patients; 18 healthcare professionals). Data was collected by making use of both qualitative (self-report questionnaire consisting of open-ended questions; interviews) and quantitative (Needs Evaluation Questionnaire) measures. A qualitative content and statistical analysis was conducted. Findings indicate that despite the expressed need for treatment to move towards a more biopsychosocial approach, the majority of the healthcare professionals in the current study are still primarily following a biomedical approach. Findings also indicate that the majority of the difficulties and frustrations experienced could be seen as being contextual problems and were not necessarily related to cancer treatment per se. Poor availability of resources and the South African population‟s diverse characteristics were responsible for the majority of the difficulties reported. Differing cultural beliefs, language barriers, illiteracy and unemployment were al seen as negatively influencing the treatment process. This is consistent with Serin et al. (2004), who reported that there is a significant relationship between the systemic nature of medical issues and the social, material and psychological difficulties cancer patients‟ experience. The systemic nature of healthcare needs highlighted in the current study emphasises the necessity for cancer treatment in South Africa to employ a more biopsychosocial approach. True collaboration between healthcare professionals working towards a common goal should thus be considered as being the ideal. Considering the socioeconomic divide and resource discrepancy between the private and public healthcare sectors in South Africa, credence must be given to the allocation of resources in the public sector. If this incongruity is to be addressed, there would have to be cooperation at government level. Assistance with regard to the allocation of funds, as well as the meticulous monitoring of the distribution thereof, is needed. Funding should be used to increase human and technical resources, as well as for staff development. Equitable care for all cancer patients, regardless of their socioeconomic status, is the ideal. The following recommendations on how to improve overall cancer care, in both sectors, can also be made: existing treatment sites need to be updated and additional sites developed; continuous research needs to be conducted; funds need to be allocated towards the development of effective transport and translation services; cultural diversity should be taken into account when developing awareness campaigns and treatment plans; healthcare professionals need to adopt a holistic approach during which attention is given to communication, establishing rapport and patient participation; and lastly healthcare professionals should also be encouraged to pay attention to their own healthcare needs as well. / PhD (Psychology), North-West University, Potchefstroom Campus, 2014

The temporal distribution and relative abundance of stable flies (Stomoxys calcitrans) (Diptera: Muscidae) in a feedlot near Heidelberg, Gauteng, South Africa / Maria Magdalena Evert

Evert, Maria Magdalena January 2014 (has links)
The stable fly, Stomoxys calcitrans (L.) is a haematophagous fly that feeds primarily on the forelegs of cattle stimulating a range of avoidance behaviours in confinement situations such as feedlots. From literature it is apparent that stable flies associated with feedlots have a significant impact on cattle especially with regard to economic parameters such as a decline in feed intake and thus a lower average daily gain resulting in less meat production due to irritation caused by painful bites. The abundance of the stable flies was studied in a large commercial feedlot near Heidelberg from October 2012 to September 2013. Two tsetse fly traps, namely the NZI and the Vavoua fly traps, were used and evaluated in determining the seasonal abundance of the stable flies. The tsetse traps proved to be most effective for sampling stable flies compared to other designs. The NZI and Vavoua tsetse type trap were compared and although there were no significant difference the NZI trap proved to be more reliable and user friendly for this study. Stable flies were more abundant from late December with a peak in numbers late in January through February and became less abundant from early March. Minimum to no fly abundance occurred in the winter months from May to June 2013. The data indicated a strong edge effect for the stable flies, the flies were more abundant in pens and corridors that were surrounded by vegetation, manure run off and holding ponds. The numbers collected in traps were correlated with stable fly counts on the cattle to be used in calculating a future threshold in chemical control. Preliminary observations on the influence of temperature, wind speed and rainfall were also made. This research will form part of a larger project to determine an integrated fly management program for the feedlot. / MSc (Environmental Sciences), North-West University, Potchefstroom Campus, 2014

Self-regulation and psychological wellbeing in a cohort of black South African teachers :|bthe SABPA study / Nelmarie Boshoff

Boshoff, Nelmarie January 2014 (has links)
The teaching profession is widely regarded as being very stressful (Klassen, Usher & Bong, 2010; Otero, Castro, Santiago & Villardefrancosl, 2010). South African teachers, especially Black teachers working in previously disadvantaged areas, have to cope with serious stressors such as overcrowded classrooms and limited resources on a daily basis (Ngidi & Sibaya, 2002; Moloi, 2010). Occupational stress of this nature is known to have significant negative implications for well-being, and chronic stress has been linked to mood and anxiety disorders, and other forms of psychopathology (Bellingrath, Weigl & Kudielka, 2009; Brock & Buckley, 2012; Mundai, 2010). However, psychological buffers could enable individuals to sustain normal development and even experience well-being, despite the presence of long-term stress (Friborg, Hjemdal, Rosenvinge & Martinussen, 2003; Ryff & Singer, 2003). Noted among these so-called protective factors, the process of self-regulation has been found to be predictive of positive outcomes with regard to physiological and psychological well-being (Hofer, Busch & Kärtner, 2011; Peterson & Seligman, 2004). Self-regulation has, however, been found to represent a resource susceptible to depletion with repeated use, and there have been contradictory reports regarding the long-term sustainability of self-regulation capacity (Converse & DeShon, 2009; Ryan & Deci, 2008). No longitudinal studies could be found that explore the natural progression of self-regulation in a highly stressful context, and how changes in self-regulation are associated with changes in stress and well-being levels. This thesis consists of three sub-studies that are reported in three manuscripts. In the first of these sub-studies the levels of occupational stress and mental well-being in a cohort of Black South African teachers were investigated, including how these two variables are related to each other. The second sub-study aimed firstly to investigate the association between self-regulation and Black South African teachers’ self-reported levels of mental well-being. Secondly, it aimed to determine the role of the sub-constructs of the self-regulation process in the teachers’ selfreported levels of mental well-being. The aim of the third article was also two-fold. It first aimed to determine the natural progression of self-regulation within a highly stressful work context over a period of three years. It then aimed to determine how long-term changes in the selfregulation of individuals finding themselves in high-stress working conditions are associated with changes in their self-reported levels of stress and mental well-being. Black South African teachers (N=200, 101 men, 99 women) of ages ranging from 25 to 65 years from the North-West province of South Africa participated in the baseline phase of the SABPA project in 2008. Of the original 200 participants, a total of 173 teachers (88 men, 85 women) took part in data collection for the follow-up study in 2011. Data were collected by making use of quantitative measures (Teacher Stress Inventory (Boyle, Borg, Falzon & Baglion, 1995); General Health Questionnaire-28 (Goldberg & Hillier, 1979); Mental Health Continuum-Short Form (Keyes, 2006); Short Self-Regulation Questionnaire (Carey, Neal & Collins, 2004)) that have been validated for use in the South African context. The findings indicate that this group of teachers experienced high levels of stress, and symptoms indicative of mental illness to an extent that warrants psychiatric intervention. However, participants also reported higher than expected levels of mental health. The findings further indicated that self-regulation contributed positively to the participants’ mental health levels. The longitudinal findings also indicated improvements in this group of teachers’ selfregulation levels over time, and that these long-term changes in self-regulation were positively associated with changes in participants’ mental health. Recommendations for future investigations on the role of self-regulation in well-being that flowed from this research include extending research to other cultural groups and general populations; use of multiple or mixedmethod approaches to provide more insight into the participants’ short- and long-term experience of their working environment, their levels of stress and well-being and their self-regulation levels; investigating the psychological perspective on stress and exploring the concept of optimal self-regulation and the maintenance thereof. The study provided a holistic insight into the importance of self-regulation as protective factor in a highly stressed context, especially with regards to the promotion of mental well-being on a short term and long term basis. / PhD (Psychology), North-West University, Potchefstroom Campus, 2014
