Thesis (M. Tech.) -- Central University of Technology, Free State, 2007 / Cerebrovascular disease and coronary heart disease (CHD) are of the most important causes of morbidity and mortality amongst South Africans. The risk factor prevalence for stroke and CHD becomes altered by changes in lifestyle, including diet. In general it is suggested that lifestyle management should be the first choice when having to treat patients with increased cardiovascular risk. The prudent low-fat, high-fibre diet is regarded as an apparently healthy diet. It is suspected that this diet is effective for the control of known coronary risk factors as well as raised clotting factors. Research studies have shown the addition of dietary fibre to the diet as a promising therapeutic agent for the limited control of known coronary risk factors. The physiological effects of dietary fibre in humans are significantly influenced by the degree to which fibre is fermented in the colon. Fermentation results in the production of short-chain fatty acids (SCFAs); acetate, propionate and butyrate. The aim of this study was to examine the possible effects of different combinations of short-chain fatty acids on some metabolic risk markers. In this study a group of westernised African male volunteers was recruited and randomly assigned to three groups. Group one received a placebo. Group two received a supplement containing 50% acetate and 50% propionate. Group three received a SCFA supplement in the ratio of 70% acetate, 15% propionate and 15% butyrate. Supplementation was sustained for a period of six weeks. Blood samples were drawn during the different visits. At baseline the study group represented a group of black African men without any apparent metabolic or physical abnormalities. All measured variables fell within the normal range. In the placebo group, there was a statistically significant decrease in plasma fibrinogen levels from baseline to the end of supplementation. In the acetatepropionate supplement study group a statistically significant decrease in factor VIII (from 91.1 ± 11.2 to 90.9 ± 8.3%, respectively), and ATIII (from 114.3 ± 13.1 to 108.34 ± 9.5%), as well as a statistically significant decrease in low-density lipoprotein cholesterol (LDL-C) from 3.10 ± 0.79 to 2.64 ± 0.73 mmol/L. The significant increase in %HDL-C from 26.3 ± 6.5 to 30.2 ± 9.3% should also be noted. Both triglycerides (8%) and plasma fibrinogen (2%) showed a statistically significant increase. However, these changes are of no clinical significance. For the high-acetate supplement study group (with the addition of butyrate), a statistically significant decrease in factor VII (from 102.5 ± 13.7 to 101.1 ± 6.4%), VIII (from 92.6 ± 12.8 to 87.6 ± 6.0%), ATIII (from 109.2 ± 16.0 to 103.0 ± 9.9%) as well as fibrin monomer concentration (from 13.9 ± 2.2 to 12.1 ± 3.6 mg/L), were measured. Fibrin network compaction increased significantly from 14.2 ± 4.6 to 13.7 ± 4.0%. Other changes include a statistically significant increase in the serum-TC of 4.2%. From the results it is evident that the acetate-propionate supplement, with exclusion of butyrate, has a beneficial effect on metabolic parameters when compared to a highacetate- propionate supplement. The results do provide evidence of a possible therapeutic application for the propionate-acetate containing supplement. The specific mechanism should, however, still be investigated. It can be concluded from this study that acetate, propionate and butyrate each have different effects on human metabolism. It is evident that the use of a mixture of acetate and propionate may have a beneficial effect on patients at risk of developing CVD. Further studies that investigate the optimum ratio of these two products may lead to the development of a naturally derived therapeutic product for the prevention or treatment of CVD in black African men, as well as the population at large.

Thesis (M. Tech.) -- Central University of Technology, Free State, 2007 / The lack of a standardized lighting instrument to be used in conjunction with existing photographic methods to document rock art, is a problem experienced in archaeological circles. Through interviews with archaeologists and an investigation into existing photographic methods concerning the photographing of rock art, a demand for a portable and modular lighting instrument was confirmed. The aim of this study, then, was to develop a prototype lighting instrument to fill this void. The design and manufacture of the modular lighting instrument entailed the harnessing of the technological advances made in the field of rapid prototyping. A brief overview of the San/Bushmen of Southern Africa is given to stress the importance of this study and to emphasise the importance of the art of the Bushman in our collective art heritage. An overview of the documenting of rock art and therewith an investigation into documented works of rock art and rock engravings by the San/Bushmen serves as a point of departure for the present inquiry. Tests undertaken with the modular lighting instrument, and a comparison of the results so obtained with existing photographic methods, showed that with the use of the modular lighting instrument, an improvement in illumination, rock-face texture and colour contrast in the images was obtained. The modular lighting instrument helps to create and regulate a suitable lighting environment irrespective of natural lighting circumstances and environments. It produces better results when it comes to documenting rock art in comparison to existing methods of documentation. Continued study for the development of the modular lighting instrument is recommended in order to produce more constant results.

Thesis (M. Tech. (Communication)) -- Central University of Technology, Free State, 2015 / The central role of language in governance need not be argued; it is self-evident. Effective communication between the political leadership and the state administration, between individual government bodies and institutions, within these bodies and institutions, and between the government and its citizens, which is a prerequisite for good government, occurs mainly through language.

Thesis (M. Ed. (Education)) - Central University of Technology, Free State, 2014 / The goal of the education system is to increase cognitive capacity, competencies and skills such as acquiring new knowledge, recalling facts and figures and applying this information to reasoning, understanding and solving problems. To achieve all these competencies teachers and lecturers traditionally use Bloom’s Taxonomy of Learning Domains. The competencies and skills as described by Bloom are measured by standardised intelligence tests. Society takes it for granted that the higher a person’s IQ (Intelligence quotient), the better he/she will perform at school level. But what happens after school? While cognitive intelligence may be able to predict quite accurately how one will perform at school, it predicts very little else in the way of social performance and interaction after school. As such, IQ is a rather weak predictor of performance in interpersonal relations, at work and in coping with a wide variety of challenges that surface in the course of one's life on a daily basis (Wagner, 1997). Some writers makes a strong case that people owe their success in their professional careers to much more than mere IQ. Wagner reviews data and offers convincing cases to show that an IQ above 110, fails as an accurate predictor of success in a career. In other words, you need to be smart enough to handle the cognitive complexity of the information you need for a given role or job, be it engineering, law, medicine, or business. But after reaching this threshold of “smart enough,” your intellect makes little difference. Wagner concludes that IQ alone predicts just 6 to 10 percent of career success. It has been argued for over a century, as early as Charles Darwin that something is missing from the human performance formula that is needed to explain why some people do very well in life while others do not, irrespective of how cognitively intelligent they may be. One of the first attempts by psychologists to identify additional predictors of performance in other aspects of life was made by Edward Thorndike (1920) when he described "social intelligence" as the ability to perceive one's own and others' internal states, motives and behaviours, and to act towards them appropriately on the basis of that information. Mayer, Salovey and Caruso (2000:273) state that emotional intelligence includes “the ability to perceive, appraise and express emotion accurately and adaptively; the ability to understand emotion and emotional knowledge; the ability to access and generate feelings where they facilitate cognitive activities and adaptive action; and the ability to regulate emotions in oneself and others”. All of these skills are necessary for the teacher to function successfully in the classroom. The question is: does the modern teacher have the necessary EI skills? This dissertation explores and describes the level of Emotional Intelligence of the first year student teachers at the Central University of Technology, Free State. Seventy-nine (79) students were tested during 2012 and 2013 to establish whether they have the necessary levels of Emotional Intelligence to ensure that they will be able to become good classroom leaders upon entering the teacher’s profession. Traits of Emotional Intelligence were assessed by means of the Trait Emotional Intelligence Questionnaire (TEIQue). The study investigates the Emotional Intelligence attributes and skills that a teacher will need to become a good classroom leader. The study examines the four main areas tested in the TEIQue, namely the well-being, the emotionality, the sociability and the self-control of the student teacher. Findings suggest that the student teachers still need to develop their emotional intelligence as their results fall in the lower level of the acceptable range.

Thesis (Phd. (Education )) - Central University of Technology, Free State, 2015 / For learners to be effective computer applications users, they need three basic skills – computer literacy, computer fluency and intellectual and reasoning skills to apply computational techniques or computer applications to the problems and projects in a field. Computational thinking as addressed in the first literature chapter is the description and the promotion of new ways of thinking in an increasingly digital age. A computational thinker must constantly engage in technology advancements. Computational thinking is a way of solving problems and is a cognitive or a thinking process. To flourish in the world of work, computational thinking has to be a fundamental part of the way learners think and understand the world. It describes the mental activity in formulating a problem to allow a computational solution. The solution can be carried out by the learner or the computer or a combination of learner and computers. Problem-solving competency as addressed in the next literature chapter involves the ability to acquire and use new knowledge, or to use old knowledge in a new way to solve problems that are not routine. Problem-solving as a skill involves a range of processes that includes analysing, interpreting, reasoning, predicting, evaluating and reflecting. Learners need profound Computer Applications Technology (CAT) knowledge and a general reasoning ability as well as investigative strategies for solving ill-defined problems. To address the research questions, the researcher employed the QUAN-QUAL design in this study. In this study the quantitative method was used to gather data relating to the education of teachers, in-service training received and answers to certain computational thinking skills and problem-solving skills. It was also used to test the relationship between problem solving and computational thinking skills. A Likert-scale type questionnaire was completed by 150 CAT teachers. In addition, this study also employed the qualitative method with semi-structured interviews to gather data relating Abstract vi to problem solving and computational thinking skills. Eight CAT teachers were interviewed to ascertain the afore-mentioned. A pilot study was conducted with the aim to test the research approach and to identify potential problems that may affect the quality and validity of the results. The wording of some questions in the questionnaire was altered to ensure that the instrument measures what it is supposed to. Descriptive statistics in this study was used to describe the findings and the inferential statistics used to test the hypotheses and draw conclusions from the quantitative statistics. For qualitative data, thematic analysis was used to analyse the original data obtained from the semi-structured interviews. To promote critical thinking skills, teachers must engage learners in higher-order thinking. Findings show that teachers do not always use classroom practices that encourage critical thinking. It was encouraging that the majority of teachers do allow group work in the CAT classroom, as group work is an important facet in computational thinking and problem solving. The study culminates in a computational thinking and problem-solving toolkit developed by the researcher. This toolkit is intended primarily for facilitators (such as CAT subject advisors or CAT mentor teachers) to enable them to conduct workshops for fellow CAT teachers. By using this toolkit, teachers will gain an understanding of what computational thinking skills and problem-solving skills are and how to develop these skills in Grades 10 – 12 CAT learners.

The research investigates the retention of employees in the institutions of higher learning and the focus is placed on the Central University of Technology: Free State (CUT). The research is undertaken because the employees at the Central University of Technology: Free State, are resigning from their positions and join rival institutions and other organisations. This creates a problem on part of students, fellow employees and management. There is therefore, a need to find reasons behind these mass resignations of employees and also to look at the retention strategies that can be employed to keep employees at the Central University of Technology: Free State. In order to address the above purpose of the research, various retention strategies to keep talented employees are discussed, and factors that lead to employees leaving the institutions are also placed under the spotlight. The discussion shows that talent management has a direct relationship with employee needs and motivation. Qualitative and quantitative methods of research are used to analyse the retention strategies employed at the Central University of Technology: Free State. The findings of the research reveal that factors such as working environment, satisfying work-life, personal career development, emotional exhaustion as well as rewards versus performance exacerbate mass exodus of talented employees at the institution. It is also disclosed that there are retention strategies in place but are not effectively implemented. The findings revealed that managers and supervisors play crucial roles in the interpretation and implementation of strategies. Working conditions should be improved so that employees stay with the institution and perform to the best of their ability. Training should be made compulsory for every employee as it provides necessary skills. Best performance and rewards should match performance in order to keep employees at the institution. / Public Administration & Management / M.Admin. (Public Administration)

Thesis (PhD (Curriculum Studies))-- University of Stellenbosch, 2009 / ENGLISH ABSTRACT: The aim of this study was to develop a curriculum framework for engineering introduction programmes offered at a higher education institution, using a case study design. The South African government is attempting to redress the social inequalities which prevailed in the education sector during the apartheid era. One of their efforts has involved the widening of access to diverse groups in society in order to increase participation within the higher education sector. However, many students attempting their higher education studies are academically under prepared. This is mainly due to insufficient life skills, communication skills, numeric skills and literacy skills. The lack of these skills has inspired various international and national higher education institutions to develop academic programmes aimed at bridging the gap that exists between secondary schooling and higher education. Introduction programmes for prospective engineering students have to ensure high-quality curriculum development procedures in order to secure these students’ academic success throughout their engineering studies. This, in turn, leads to quality graduates and addresses the huge shortage experienced by the industry. An overview of the contextual and conceptual views on curriculum development is given against the backdrop of the current higher education legislation in South Africa. The overview regarding curriculum development links the introduction programme curriculum to generic learning outcomes specifically set at the National Qualification Framework Level 4. It suggests the application of continuous assessments, in line with outcomes-based education criteria, together with quality assurance in order to fit the Higher Education Quality Committee and the Engineering Council of South Africa’s accreditation criteria applicable to higher education institutions. During the design and methodological stages, it was established, by means of a theoretical investigation, that the first phase of this study determines whether students that successfully completed the introduction programme perform academically better than students entering the diploma programmes directly. The theoretical investigation also established that the second phase of this study determines if the diploma students dropped out of the programme for reasons other than academic performance. A triangulation approach was used to increase the validity of the empirical part of the study and to enhance the rigorous use of both quantitative and qualitative data. The study results shed light on the need for introduction programmes. In addition, it proposed a curriculum framework for improved engineering introduction programmes at the Vaal University of Technology. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om kurrikulumraamwerk vir oorbruggingsprogram vir ingenieurswese-studente in hoër onderwys te ontwikkel. Die kurrikulumraamwerk is ontwikkel deur middel van gevallestudie wat die implementering van oorbruggingskursusse in die ingenieurswese indringend ondersoek het. Die huidige Suid-Afrikaanse regering poog om die sosio-politieke wanbalanse as nalatenskap van apartheid, uit te wis. Dit word gedoen deur middel van inisiatiewe waarin onder meer hoër onderwys prominente vennoot is wat aan diverse samelewing gelyke geleenthede bied. Die huidige, meer toeganklike bedeling in hoër onderwys in Suid-Afrika het groot toename van studente uit histories agtergeblewe gemeenskappe tot gevolg gehad. Die meeste studente wat in hierdie konteks die hoëronderwyssektor betree, blyk in groot mate onvoorbereid te wees vir hoër onderwys vanweë hul gebrek aan lewens-, kommunikasie-, numeriese en taalvaardighede. Hierdie tendens kom ook op internasionale vlak voor. Dit het inisiatiewe ten opsigte van akademiese ontwikkeling op nasionale sowel as internasionale vlak genoodsaak. Die doel van akademiese ontwikkeling is primêr om die gaping tussen die skool en hoër onderwys te oorbrug. Oorbruggingskursusse moet van hoë gehalte wees om sodoende te kan verseker dat voornemende studente vir hoër onderwys, en vir die doel van hierdie studie meer spesifiek ingenieurstudente, van groter akademiese sukses verseker kan wees. Die suksesvolle implementering van oorbruggingskursusse vir ingenieurswese-studente behoort in groot mate tot beter gehalte gegradueerde te lei en bydrae te lewer tot die vraag na ingenieurswese-studente vir die nywerheidswêreld. Kontekstuele en konsepsuele beskouings ten opsigte van kurrikulumontwikkeling in die hoër onderwys in Suid-Afrika word deur generiese leeruitkomste bepaal. Hierdie uitkomste is op vlak 4 van die land se Nasionale Kwalifikasieraamwerk vasgepen. Dit het ook tot gevolg dat alle programme volgens amptelike Departement van Onderwys-dokumente aan deurlopende assessering onderwerp moet word, dat die gehalte van die kursus onderworpe is aan die gehalteversekeringskriteria van die vi Hoëronderwys se Gehaltekomitee (‘HEQC’) en dat dit moet voldoen aan die vereistes van die Ingenieursraad van Suid-Afrika. Teoretiese raamwerk is tydens die ontwerp- en metodiekstadium van die studie daargestel. Die doel van hierdie eerste fase van die studie was om te bepaal of diplomastudente wat die oorbruggingskursusse suksesvol voltooi het, akademies beter gepresteer het as daardie studente wat nie die oorbruggingskursus gevolg het nie. Die tweede studiefase het bepaal of die diplomastudente hul studies vir redes gestaak het wat moontlik nie met akademiese sukses verband hou nie. Die navorsing het van triangulasie gebruik gemaak, ten einde die doeltreffende gebruik van sowel kwantitatiewe as kwalitatiewe data te verhoog. Die resultate van die studie werp lig op en onderstreep die behoefte aan oorbruggingskursusse. Die navorsing beveel kurrikulumraamwerk aan vir die ontwerp van verbeterde oorbruggingskursusse in die ingenieurswese aan die Vaal Universiteit van Tegnologie.

Thesis (PhD)--Stellenbosch University, 2006. / Bibliography / ENGLISH ABSTRACT: This study is aimed at developing a curriculum framework for consumer learning at a higher education institution, using a case study design. To determine the need for consumer learning at the Cape Peninsula University of Technology – the “bounded context” of the study – a situation analysis was conducted as the first phase of curriculum development. Methods to triangulate data included the use of quantitative and qualitative research methods, together with a thorough literature study. The two sets of empirical data were obtained from two research instruments, namely self-administered survey questionnaires and semi-structured interviews with learning facilitators (lecturers) at the institution. The survey amongst first-year students was used to assist in the needs assessment for curriculum development at the CPUT and to determine the knowledge, skills, values and attitudes of first-year respondents regarding consumer rights and responsibilities, as well as other consumer-related issues. This not only provided data to analyse the situation, but also assisted in the planning and development of a curriculum framework for consumer learning. The researcher used semi-structured interviews to determine the views and perceptions of learning facilitators regarding the importance of consumer learning, and to gauge the need for such learning at the institution. Aspects relating to the contents, teaching strategies, level of introduction, potential for critical crossfield outcomes development, benefits and major obstacles in the implementation and/or integration into the curriculum were also investigated. The two-tiered situation analysis indicated that students expressed a clear need for consumer learning at the Cape Peninsula University of Technology, especially regarding the areas of consumer rights and responsibilities. The importance of consumer learning and the “readiness climate” from the perspective of the learning facilitators was also clearly established. The study culminated in the development of a curriculum framework for consumer learning that is compatible with the requirements of the South African Qualifications Authority and the Higher Education Qualifications Framework in South Africa. Key findings reported in the form of a curriculum framework could serve as a guideline for the planning and implementation of a consumer learning programme at the Cape Peninsula University of Technology. / AFRIKAANSE OPSOMMING: Hierdie studie is onderneem met die doel om ‘n kurrikulumraamwerk vir verbruikersleer aan ‘n hoëronderwysinstelling te ontwikkel. ‘n Gevallestudie-benadering is gebruik om die sosiale verskynsel van verbruikersleer te ondersoek. Om die behoefte aan verbruikersleer aan die Kaapse Skiereilandse Universiteit van Tegnologie – die konteks van die studie – te bepaal, is ‘n situasie-analise onderneem as die eerste fase van kurrikulumontwikkeling. Metodes van triangulasie in hierdie navorsing sluit die benutting van kwantitatiewe en kwalitatiewe gegewens in, asook ‘n literatuurstudie. Die twee stelle empiriese gegewens is verkry vanuit ‘n self-geadministreerde opnamevraelys aan studente en onderhoude met leerfasiliteerders (dosente) aan die instelling. Die doel van die opnamevraelys was om te help met die behoeftebepaling vir kurrikulumontwikkeling aan die Kaapse Skiereilandse Universiteit van Tegnologie, en veral om die kennis, vaardighede, waardes en houdings van eerstejaarrespondente met betrekking tot verbruikersregte en -verantwoordelikhede te bepaal. Dit het nie alleen insig in die situasie-ontleding gegee nie, maar het ook gehelp met die beplanning en ontwikkeling van ‘n kurrikulumraamwerk vir verbruikersleer. Die doel met die gebruik van semi-gestruktureerde onderhoude in hierdie studie was om die navorser in staat te stel om die sienswyse en persepsies van leerfasiliteerders met betrekking tot die belangrikheid van verbruikersleer, asook die behoefte daarvoor by die instelling te bepaal. Aspekte wat verband hou met die inhoud, onderrigstrategieë, vlak van bekendstelling, potensiaal vir kritieke uitkomsontwikkeling, voordele en vernaamste struikelblokke in die implementering en/of integrasie van die kurrikulum is ook getoets. Die situasie-analise dui daarop dat studente aan die Kaapse Skiereilandse Universiteit van Tegnologie ‘n behoefte het aan verbruikersleer, veral met betrekking tot die bevordering van verbruikersregte en -verantwoordelikhede. Die belangrikheid van verbruikersleer en die “gereedheidsklimaat” daarvoor vanuit die perspektief van die leerfasiliteerders is ook bevestig. Die resultaat van die navorsing het gelei tot die ontwikkeling van ‘n kurrikulumraamwerk vir verbruikersleer wat versoenbaar is met die vereistes van die Suid-Afrikaanse Kwalifikasie-Owerheid en dié van die Hoëronderwys-Kwalifikasieraamwerk in Suid-Afrika. Sleutelbevindings in verband met verbruikersleer is ook in die raamwerk opgeneem. Hierdie bevindings kan as ‘n riglyn dien vir die beplanning en implementering van ‘n verbruikersleerprogram aan die Kaapse Skiereilandse Universiteit van Tegnologie.

Thesis (MEd (Curriculum Studies)--University of Stellenbosch, 2007. / Culinary studies is a relatively young and unfamiliar field of study which engages the application of life and natural sciences, business and technology in a food-specific environment. The growth in the demand for training, re-training and continuing professional development in the culinary arts can be attributed to factors such as enhanced culinary programmes at high school level, an increased level of education and expectation about food in general, growth in culinary tourism and highly polished food magazines or other publications. The celebrity status of high-profile chefs and a stronger economy that enables more people to explore fine dining and gourmet food can be added to the list of factors that influence the interest in culinary arts as a profession. The number of qualified culinary professionals has increased over the last 10 years in South Africa, providing a large corps of people with a good understanding of this field of study and a need for continuing professional development opportunities. This study was a response to the challenges of the demand for continuing professional development opportunities from this growing body of culinary professionals. The demand for continuing professional development opportunities in culinary studies is becoming more complex and challenging for both learner and teacher. Although institutions that provide training in hospitality are also in the business of culinary education, their perspectives and focus are quite diverse. Culinary education can therefore be improved through a deeper understanding of the curriculum development process combined with the expectations of both the industry and the individual. A fundamental shortcoming in the field of culinary education is often that persons with limited expertise in the field of curriculum studies bear the primary responsibility for addressing curriculum challenges. The development of curricula for professional development in culinary studies subsequently happens at the expense of understanding the curriculum. The primary aim therefore of this study was to identify and propose a curriculum framework for continuing professional development in culinary arts. This framework might contribute to providing a curriculum foundation, credibility to the broad hospitality industry and specifically to culinary studies, as well as to the securing of some uniformity of standards over the spectrum of culinary qualifications. A scientifically validated situational analysis was executed by means of focus group discussions, personal interviews, curriculum comparisons and an electronic mail questionnaire survey, which mainly generated qualitative data. These techniques were used in triangulation as research instruments to investigate the needs for continuing professional development in culinary arts and the availability of curricula to address these needs. The greatest challenges in culinary studies were reflected in the complexity and multidisciplinary nature of this relatively undefined industry and field of study. The intricate relation, interaction, collaboration and contexts between secondary schools, various culinary training institutions, industry and culinary professionals were investigated. The data generated confirmed the need for training and development opportunities to improve the professional status of culinary professionals in South Africa The promotion of a change in direction for culinary studies development in South Africa could ensure future growth as a discipline cognitively and professionally, in line with international standards, procedures and practices. The range of challenges and changes facing the industry varies from social issues to the educational issues of qualifications and credible accreditations, which are addressed in the proposed curriculum framework. The lack of more empirical research in this field of study is an indication that both students and professionals should be encouraged to do the relevant research and that higher education institutions should provide the opportunities and structures for such research.
