Die studie foku.s op die verwantskap tussen sin vir koherensie as 'n intrinsieke hanteringsbron aan die een kant, en elk van streshantering, algemene gesondheid en sielkundige uitbranding aan die antler kant. Vraelyste wat hierdie veranderlikes meet is aan 200 bestuurders gegee om te voltooi. Die bevindinge van hierdie studie toon aan dat bestuurders met 'n hoi! sin vir koherensie goeie algemene gesondheid geniet. Die bestuurder met 'n hoi! sin vir koherensie behoon dus meer e.ffektief te junksioneer in die werksiruasie as die bestuurder met 'n lae sin vir koherensie. Voons is ook bevind dar 'n hoi! sin vir koherensie nie noodwendig aanleiding gee tot lae vlakke van stres of van sielkundige uitbranding nie. Aanbevelings word gedoen oor hoe om die negatiewe gevolge van stres en sielkundige uitbranding te venninder en algemene gesondheid te bevorder, ten einde die bestuurder se potensiaal optimaal benut. / This study focuses on the relationship between sense of coherence as an intrinsic coping mechanism. and work stress, general health and psychological burnout. To measure these variables, questionnaires were completed by 200 managers. The findings of this study indicate that managers with a high sense of coherence experience good general health. The manager with a high sense of coherence should therefore junction more efficiently in a work situation·than the manager with a low sense of coherence. It was also found that a high sense of coherence does not necessarily lead to low levels of stress nor of psychological burnout. Recommentfations are made on how to reduce the negative effects of stress and psychological burnout and how to improve general health in order to make optimal use of the manager's potential. / Industrial and Organisational Psychology / MCom (Bedryfsielkunde)

I denna studie undersöker vi matematiklärares olika synsätt utifrån deras erfarenheter kring visuella representationer och aspekter av bråk. Lärare intervjuades om en uppsättning problem som deras elever fick lösa, vilka var de metoderna som användes. Vi undersöker därav även om det finns några samband mellan klassresultaten och matematiklärarnas olika synsätt. Tre olika teorier användes som ramverk vid både metodövervägandet och analysen; Fyra utvecklingsstadier vid inlärning med representationer, fem aspekter av bråk och pedagogical content knowledge. Resultaten visar att det finns likheter och skillnader i deltagande lärares synsätt. Några likheter var att alla deltagande lärare finner visuella representationer att vara ett användbart hjälpmedel vid utveckling av elevers förståelse samt att de alla uttrycker en större bekantskap med aspekten del-helhet jämfört med de övriga aspekterna. Några skillnader mellan lärarnas synsätt var att de har olika inställningar till huruvida bråk uppfattas som svårt för eleverna men också i vilken utsträckning visuella representationer ska användas i årskurs 9. Vid analys av klassresultaten finner vi några samband där eleverna har svårare för uppgifter med areamodeller som inte är indelade i lika stora delar, uppgifter med tallinjer och uppgifter där eleverna ska uttrycka sig med ord. Lärarnas kommentarer till detta är att eleverna saknar förståelse för den matematik som ska användas och att eleverna på så sätt använder en felaktig metod. Lärarna kommenterar även att vissa uppgifter i studien kräver en större begreppsförståelse vilket påverkar elevernas resultat på uppgifterna. / In this study we examine mathematics teacher’s verity in their reasoning and their different perspectives about visual representations and sub-constructs of fractions. Teachers were interviewed about task that their students solved, which were the methods used in this study. Therefor we also examine if there are any correlations between the teacher’s different perspectives of visual representations and the classes results on fraction tasks. The study was based on three theoretical frameworks; Four stages through the use of representations, five sub-constructs of fraction and pedagogical content knowledge. The methodological consideration and analysis were based on these theories. The result showed that there were some similarities and differences in the teacher’s reasoning. A similarity was that all participated teachers found visual representations as a helpful tool when teaching fractions for student’s conceptual understanding. Another similarity was that all teachers were more familiar with the part-whole sub-construct than the other subconstructs of fraction. Some differences in the teacher’s reasoning were if they found fraction difficult or not for the students and in which extent visual representation should be used in the ninth grade. When the class results were analyzed some connections were found. Student have difficulties with tasks where area models are not equaled partitioned, with tasks related to number lines and to tasks were the students must change from a visual to a textual representation. According to the teachers comments these difficulties accurse due to that the students lacks a curtain mathematical understanding that is required when solving these tasks. This leads to the use of an inaccurate method. The teacher’s also comments that some tasks in this study requires a higher conceptual understanding which affects the classes’ results.

Leadership is a problematic topic at universities and it is therefore difficult to isolate a leadership theory that is applicable to Heads of Department (HODs). The manner in which HODs construe their leadership roles is the focus of this research project and the study is conducted from a constructivist perspective The university context in which HODs lead is explored in the literature overview. Definitions of leadership, general leadership theories and leadership issues in academe are investigated. The research findings are integrated into a leadership model for HODs, consisting of constructs (leadership behaviours, actions and values) and elements (leadership situations). The following contributions are made by the study: * The variety roles an HOD has to fulfil is confirmed by the study. However, this study indicates that leadership is interwoven with everything an HOD undertakes. * HODs construct their roles uniquely, but in general terms most HODs consider academic and scholarly work (own and that of the department) as part of the leadership role they fulfil. Leadership at HOD level at university incorporates both managerial and leadership ideas. * HODs consider their leadership environment to have qualities of the following known university environments: collegial, enterprise, bureaucratic and corporate. * This study identifies eight leadership themes with reference to the leadership role of an HOD at university; providing academic guidance, being a figurehead, determining the strategy and positioning the department, liaising with internal and external stakeholders, being a change agent, being a general manager, and being involved in student and staff relations. The following leadership themes can be added to the current body of literature: being a figurehead, own scholarly profile, as well as being involved in staff and student relations. Leadership at academic departments is at the heart of everything in which an HOD is involved. Leadership is thus becoming indispensable at academic departments at university. / Industrial and Organisational Psychology) / D. Com. (Consulting Psychology)

It is argued that developmental psychology is the "third discipline of scientific psychology" , emphasizing the formal aspect of behavioral continuity/change. Constructs elaborating this aspect are semantical and not empty mathematical models or fuzzy common sense concepts. Assessment is comprehensively describcd as a matrix of four components (test theory, constructs, tests, diagnostica! proces) by three levels (common sense, scientific constructs, mathematical models). Developmental psychology and assessment are confronted to conquer and extend the meaning of continuity/change, as in "convergent" and "discriminant" construct validation. Test theory, tests and the diagnostica! proces respective! y offer models, instruments and a program for assessing behavior. / Se sostiene que la psicología del desarrollo es la "tercera disciplina de la psicología científica", enfatizándose el aspecto formal de la continuidad/cambio conductual. Los constructos que elaboran este aspecto son semánticos y no modelos matemáticos vacíos o borrosos conceptos de sentido común. Se describe comprensivamente la evaluación como una matriz de cuatro componentes (teoría de los tests, constructos, tests, proceso diagnóstico) por tres niveles (sentido común, constructos científicos, modelos matemáticos). Se confrontan la psicología del desarrollo y la evaluación con la finalidad de captar y ampliar el significado de continuidad/cambio, como en la validación de constructos "convergentes" y "discriminantes". La teoría de los tests, los tests y el proceso diagnóstico ofrecen,  respectivamente, modelos, instrumentos y un programa para evaluar la conducta.

This study investigates transformational leadership at a higher education institution. The systems paradigm serves as the point of departure, while the construct `leadership', which forms the driving force of change in the organisation, and the concept `transformational leadership', are integrated to yield a mechanism for the optimal positioning of the organisation in the ambit of transformation. The results indicate that the leadership style at the higher institution in question is transformational in nature. From the literature review it became evident that although it is possible for transformational leaders to fail in the transformational strategy, the transformational leader may exhibit the most `ideal' leadership style for the higher education institution engaged in a turnaround strategy. Based on the results of the study, additional proposals are made regarding further study in the area of transformational leadership as well as possible decisions regarding human resource management for the higher education institution in question. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

The Living Standards Measure (LSM), a South African marketing segmentation method, is a wealth measure based on standard of living. This research study investigates whether a rationale can be found for the inclusion of value-related variables in this type of multivariate segmentation approach. Schwartz’s (1992; 2006) values model was used to operationalise personal values and individual-level culture – focusing on two of its dimensions, ideocentrism and allocentrism. The current positive psychology research trend manifests in the inclusion of subjective wellbeing (SWB), as measured by satisfaction with life (SWL). The primary objective of this research was to investigate at individual (and not group or societal) level whether values and SWL can be used to discriminate among multivariate consumer segments. Data were collected by means of a survey from a nationally representative sample (n = 2566) of purchase decision-makers (PDMs). The measurement instruments used were the Portrait Values Questionnaire (PVQ) and the Satisfaction with Life Scale (SWLS). A multi-group confirmatory factor analysis (MGCFA) was used to assess the psychometric properties and test the equivalence of the scales across cultural groups. MGCFA was also used to test for differences across LSM groups on the PVQ and SWLS. Centred value scores were used to test for differences between LSM groups in terms of their values and SWL, using MANOVA. The findings supported Schwartz’s theory of basic human values, and small differences were found in the PVQ values between LSM groups using the MGCFA approach. MANOVA analyses showed stronger differences across LSM groups. PDMs in the higher LSM segments were more satisfied with their lives. No significant relationships between values and SWL were found, and the effect of individual-level culture, as a higher-order dimension of four values, showed a small but significant effect on SWL. / Psychology / D.

This study focused on multilingualism as the primary linguistic cognitive objective of investigation. An integrative approach focused on second language linguistics in order to acquire a background in the cognitive foundations of language and research methodology and theoretical models for the study of phenomena, such as language planning in multicultural societies and language and ethnic diversity. To design cognitive reading methods, a literature survey was conducted regarding the latest developments in the theories pertaining to cognitive formulas of the second language learner. A quantitative experimental study was conducted, data gathered was scrutinised and a cognitive reading programme was experimentally administered to twenty primary school learners. The responses were coded, the data captured and statistically computed. Conclusions indicated that cognitive reading materials were practical, valid and reliable. Cognitive formulas hold the potential of contributing to the understanding of cognitive reading development in second language proficiency in the Foundation Phase of schooling. / Teacher Education / M.

Text in Afrikaans / Die studie fokus op die effek van krisiswerk op die helper in terme van stres, die uitbrandingsindroom en posttraumatiese stresversteuring (PTSV). Salutogeniese konstrukte as moderatorveranderlikes in die stres-siekte-verhouding word ook ondersoek. 'n Beskikbaarheidsteekproef van 52 ambulansmanne en 52 kontrolegroepwerkers is verkry. Biografiese, koherensie-, uitbrandings-, PTSV- en stresvraelyste is ingevul en statisties verwerk. Resultate dui daarop dat ambulansmanne hul werk as buitengewoon stresvol beleef en dat meer ambulansmanne diagnoseerbare PTSV vertoon. Daar blyk geen verskil tussen die twee groepe te wees nie met betrekking tot die voorkoms van uitbranding en streservaring. 'n Negatiewe verband tussen koherensiebelewing en die voorkoms van stressimptome en uitbranding is verkry. Ambulansmanne het 'n buitengewoon stresvolle werk en vertoon meer simptome van stresversteurings as mense in ander beroepe. Aanbevelings word gedoen oor hoe om die negatiewe konsekwensies van stres te verminder. / The study focuses on the effect of crisis work on the assistant in terms of stress, the burnout syndrome and post-traumatic stress disorder (PTSD). Salutogenic constructs as moderator variables in the stress-illness relationship are also investigated. An availability sample of 52 ambulancemen and 52 control group workers was obtained. Biographic, coherence, burnout, PTSD and stress questionnaires were completed and statistically processed. Results indicate that ambulancemen experience their work as exceptionally stressful and that more Ambulancemen display diagnosable PTSD. There appears to be no difference between the two groups in respect of the incidence of burnout and experience of stress. A negative connection between the experience of coherence and the incidence of stress symptoms and burnout was obtained. Ambulancemen have an exceptionally stressful job and display more symptoms of stress disorders. Recommendations are made on how to reduce the negative consequences of stress. / Industrial and Organisational Psychology / M. Com. (Bedryfsielkunde)
