Career choice patterns of learners in Eastern Cape schools with special references to the Northern Region

Kopele, Bonisiwe Unity Carol 11 1900 (has links)
The choice of a career is an important decision that a person has to make in his life. The purpose of this study was to identify factors at play at the time that learners' have to commit themselves to chosen career paths. From the literature it became,evident that there exists an interplay between personal and situational factors. This interplay results in the formation of a certain identity which is later actualised in a chosen career. The empirical study revealed that factors like the type of school attended, the school curriculum the socio-economic location of the school and the availability of guidance services played an important role in the choice of a career. Family factors and other factors such as prestige and remuneration were also influential. It appeared however that the level of a learner's career maturity would be a major factor influencing career identity formation, choice and subsequent satisfaction. / Summaries in English and Afrikaans / Een van die belangrike besluite wat In mens moet maak in sy lewe is die van In beroepskeuse. Die doel van hierdie ondersoek was om die faktore te identifiseer wat In rol speel gedurende die tyd wanneer leerders hulself verbind tot In gekose loopbaan.

Élaboration d'une approche de biosurveillance humaine pour évaluer l'exposition aux métaux et éléments traces de la population libanaise et son association avec la consommation d'eau potable

Nasser Eddine, Nessrine 08 1900 (has links)
Dans le contexte libanais, les infrastructures de traitement et d’approvisionnement en eau potable ne sont pas optimales et il existe un manque de connaissances sur l’association entre la consommation d’eau et les niveaux d’exposition aux métaux et éléments traces. La présente étude est une première tentative faisant état de l'exposition aux métaux et aux éléments traces dans des sous-groupes de la population libanaise en utilisant une approche de biosurveillance multi-matrices. Les concentrations en 11 métaux et éléments traces (aluminium (Al), arsenic (As), cadmium (Cd), chrome (Cr), cuivre (Cu), fer (Fe), plomb (Pb), manganèse (Mn), sélénium (Se), uranium (U), zinc (Zn)) ont été mesurées dans des échantillons d'urine, de cheveux et d'ongles d’orteils d'un groupe de la population et les niveaux ont été comparés en fonction de l'âge, du sexe, du tabagisme, du statut économique, de la zone géographique et de la source d'eau potable. Alors que la plupart des concentrations urinaires et d'ongles n'étaient pas statistiquement différentes entre les hommes et les femmes, les concentrations mesurées d'éléments dans les cheveux étaient statistiquement plus élevées chez les femmes que chez les hommes. Les concentrations urinaires d'Al, Cu, Se et Zn étaient statistiquement plus élevées chez les enfants comparativement aux adolescents et aux adultes. Les concentrations de plusieurs éléments dans les cheveux et les ongles (As, Cd, Pb, Mn, Se dans les cheveux et les ongles plus Al, Fe dans les ongles d’orteils) étaient significativement plus élevées chez les enfants que chez les adolescents et/ou adultes (MG chez les enfants vs. les adolescents vs. les adultes dans les cheveux: 0,009 vs 0,009 vs. 0.005 µg As/g (p<0,01); 0,046 vs. 0,016 vs. 0,022 µg Cd/ g (p<0,05); 1,16 vs. 0,580 vs. 0,627 µg Pb/g (p<0,1); 0,305 vs. 0,168 vs. 0,275 µg Mn/g (p<0,1); 0,365 vs. 0,370 vs. 0,217 µg Se/g (p<0,05) et dans les ongles d’orteils : 17,0 vs. 14,3 vs. 7,31 µg Al/g et 56,9 vs. 46,0 vs. 23,8 µg Fe/g (p<0,05). Le statut tabagique n’a aucune influence sur les concentrations de As, cd et Pb. Les niveaux de Cd, Pb et Mn étaient également statistiquement plus élevés dans les échantillons des sous-groupes ayant un statut économique inférieur (Cd et Pb dans les 3 matrices urines, cheveux et ongles d’orteils respectivement de 0,223 µg Cd/L(p<0,1); 0,062 µg Cd/ g (p<0,05) et 0,038 µg Cd/ g (p<0,01); 1,16 µg Pb/L(p<0,05); 1,84 µg Pb/ g (p<0,01) et 0,840 µg Pb/ g (p<0,01) et Mn dans les cheveux et ongles d’orteils respectivement de 0,434 µg Mn/ g (p<0,05); 0,689 µg Mn/g (p<0,05). Les mêmes tendances ont été observées pour la stratification en fonction de la zone géographique, mais la différence n'était pas statistiquement significative, sauf pour le Pb dans l'urine où les participants de Beyrouth centre avaient des niveaux urinaires significativement moins élevés que les autres zones (0,560 µg Pb/L(p<0,01). Très peu de corrélations ont été identifiées entre les sources d’eau potable et les concentrations des métaux et éléments traces dans les urines, cheveux et ongles d’orteils. Cependant, une corrélation a été trouvée entre les niveaux d’As, Cd et Pb dans les cheveux et les ongles d’orteils respectivement (r = 0,4, p<0,05); (r = 0,310, p<0,05) et (r = 0.,270, p<0,1). Dans l’ensemble, les résultats ont montré que la population était exposée à des concentrations plus élevées de certains métaux que les autres populations, une attention particulière doit être accordée à l'exposition aux As, Cd et Pb, Mn et Se. Bien que la source d'eau n'ait pas contribué à la différence dans les niveaux d'exposition, les niveaux de certains métaux et éléments traces différaient selon l'âge, le sexe, les zones géographiques de résidence et le statut économique. Il pourrait être pertinent d'étendre ce type d'enquête à une initiative de biosurveillance humaine à grande échelle dans la population libanaise afin de valider et de généraliser les résultats et d'observer les tendances temporelles dans le temps. / In the Lebanese context, drinking water treatment and supply infrastructures are not optimal and it exists a lack of knowledge on the association between water consumption and levels of exposure to metals and trace elements. The present study is a first attempt reporting exposure to metals and trace elements in subgroups of the Lebanese population using a multi-matrix biomonitoring approach. Concentrations of 11 metals and trace elements (aluminum (Al), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), selenium (Se), uranium (U), zinc (Zn)) were measured in urine, hair and toenail samples from a population group and the levels were compared according to the age, gender, smoking status, economic status, geographic area, and source of drinking water. While most urinary and nail concentrations were not statistically different between men and women, measured element concentrations in hair were statistically higher in women than in men. Urinary concentrations of Al, Cu, Se and Zn were statistically higher in children compared to adolescents and adults. Concentrations of several elements in hair and nails (As, Cd, Pb, Mn, Se in hair and toenails plus Al, Fe in toenails) were significantly higher in children than in adolescents and/or adults (MG in children vs. adolescents vs. adults in hair: 0.009 vs. 0.009 vs. 0.005 µg As/g (p<0.01); 0.046 vs. 0.016 vs. 0.022 µg Cd/g (p< 0.05), 1.16 vs. 0.580 vs. 0.627 µg Pb/g (p<0.1), 0.305 vs. 0.168 vs. 0.275 µg Mn/g (p<0.1), 0.365 vs. 0.370 vs. 0.217 µg Se/g (p<0.05) and in the nails: 17.0 vs. 14.3 vs. 7.31 µg Al/g and 56.9 vs. 46.0 vs. 23.8 µg Fe/g. Smoking status has no influence on the concentrations of metals and trace elements. The levels of Cd, Pb and Mn were also statistically higher in the samples of the subgroups with a lower economic status (Cd and Pb in the 3 matrices urine, hair and toenails respectively of 0.223 µg Cd/L (p<0, 1);0.062 µg Cd/g (p<0.05) and 0.038 µg Cd/g (p<0.01);1.16 µg Pb/L(p<0.05);1.84 µg Pb/ g (p<0.01) and 0.840 µg Pb/g (p<0.01) and Mn in hair and toenails respectively 0.434 µg Mn/g (p<0.05), 0.689 µg Mn/g (p <0.05). The same trends were observed for stratification according to geographical area, but the difference was not statistically significant, except for Pb in urine where participants from central Beirut had significantly lower urinary levels than the others zones (0.560 µg Pb/L (p<0.01). Very few correlations have been identified between the sources of drinking water and the concentrations of metals and trace elements in urine, hair and toenails. However, a correlation was found between As, Cd and Pb levels in hair and toenails respectively r = 0.4, p<0.05), r = 0.310, p<0.05) and r = 0.270, p<0.1). Overall, the results showed that the population was exposed to higher concentrations of some metals than other populations, particular attention should be paid to exposure to As, Cd and Pb, Mn and Se. Although water source did not contribute to the difference in exposure levels, levels of some metals and trace elements differed by age, sex, smoking status, geographic areas of residence, and economic status. It might be relevant to extend this type of investigation to a large-scale human biomonitoring initiative in the Lebanese population in order to validate and generalize the results and to observe temporal trends over time.

Hindrances to learning to program in an introductory programmimg module

Marokane, Thomas Selakane January 2017 (has links)
Introductory programming failure rate among students is high worldwide, including in South Africa. The failure rate remains a subject for investigation due to a high number of students who find learning to program difficult. This study evaluates factors that contribute to high failure rates in an introductory programming module at University of South Africa. The study evaluates curriculum, programming syllabus, and personal factors to evaluate reasons for high failure rates. Quantitative and qualitative research approaches are used to identify learning hindrances. The research results show that personal factors are the leading contributing factors, followed by the curriculum and then the programming syllabus. Personal factors relate to time, personal reasons, and commitments; curriculum involves tutorials; and programming syllabus factors are linked to programming concepts and application. The findings have implications for how teaching and learning in introductory programming can be improved. The study provides recommendations for improvement and future studies.

Emigration of South African migrants to Australia and New Zealand : a mixed-method study

Marcantuono, Letitia 01 1900 (has links)
Over the past 30 years South Africa has lost valuable human capital due to high volumes of emigration. South Africa has also seen numerous changes in its political, economic and social structure specifically in these decades, but little investigation has been done into the possibility of an association between political, economic and social, as well as personal factors, and the decision to leave South Africa. This study refers to Lee’s Migration Model (1966) that was used as a broad theory for migration. The model involves four sets of factors: factors associated with the area of origin, factors associated with the area of destination, intervening obstacles and personal factors. Maslow’s Hierarchy of Needs Theory also explains the personal motivational theory for migration. Lee’s Model of Migration is used to investigate which political, economic, social and personal factors in the area of origin (South Africa) pushed South African emigrants to leave the country. It also investigates which political, economic, social and personal factors in the area of destination (Australia and New Zealand) pulled South African emigrants toward these countries. This study involved mixed-methods research (Creswell, 2009), thus the data collection methods were both qualitative and quantitative. The study followed a sequential exploratory strategy in two stages with the qualitative data collection occurring first, followed by a quantitative study – ‘QUALquan’ study. The data are mixed between analysis of the qualitative data and the quantitative data collection (Creswell, 2009:211). The qualitative data collection instruments used in the first stage of the study in 2009, were face-to-face interviews consisting of one focus group and six personal interviews in New Zealand, as well as twelve personal interviews in Australia. In the second stage of the study in 2015, namely the quantitative research, respondents were selected by contacting 17 closed (secured) Facebook groups that were formed for South Africans living either in Australia or New Zealand. There is no alternative sampling frame available since emigrants do not need to declare themselves as migrants on a work visa, furthermore, official documentation is not accessible to the public. A quantitative data collection instrument was administered with an online questionnaire. In the Australian Facebook groups, 137 respondents completed the questionnaire, and in New Zealand Facebook groups, 118 respondents, which adds up to a total of 255 respondents who completed the questionnaire. The results concluded that South Africa’s governance framework, its infrastructure and legislation acted as political push factors motivating South Africans to emigrate, while an uncertain economy contributed as an economic push factor. Socially, a perception of a limited future and a narcissistic society is what pushed South Africans to emigrate. Personal push factors that drove the emigration decision included, unmet physical, safety, belonging and esteem needs. The political factors that pulled South African emigrants to Australia and New Zealand involved effective government services and governmental aid. Economic pull factors included economic certainty and a lower cost of living. Social pull factors proved to be familiar circumstances and a better future. Personal pull factors were safety, belonging and self-actualisation needs. This mixed-method approach focussed on the gap to a followup study that was identified in previous individual qualitative and quantitative studies. These results may assist the South African government to take measures that ensures the retention of highly skilled citizens. / Business Management / M. Com. (Business Management)

Cultural factors associated with management of a breast lump amongst Xhosa women

Mdondolo, Nosipho 01 1900 (has links)
A qualitative research design and an ethno-nursing research method were used to identify cultural factors influencing Xhosa women's health seeking behaviours associated with breast lumps. Focus group interviews were conducted to obtain data. The research results revealed that these Xhosa women with breast lumps did not disclose some cultural factors which influenced their health seeking behaviours associated breast lumps. Registered nurses, sharing the same culture and language as the Xhosa women, revealed that Xhosa women with breast lumps sought treatment from traditional healers, prior to seeking medical care from the hospital and/or clinics. When they arrive at the hospital/clinics the breast lumps have often progressed to advanced ulcerated breast cancer, with poor prognoses and poor treatment outcomes. Xhosa women lacked knowledge about the management of breast lumps. Health promotion efforts should address this issue at Primary Health Care services in the Eastern Cape. / Health Studies / M.A. (Health Studies)
