Thesis (M. Ed. ) - Central University of Technology, Free State, 2014 / The aim of this study was to investigate the English Language Proficiency of non-English speaking learners in the Foundation Phases. An in-depth literature study was conducted to investigate this phenomenon. The historical background of language provision in South-African schools, the issue of language and cognition and different aspects of mother tongue education was touched on. The implicaitons of the current situation of the Language of Teaching and Learning (LoLT) for teaching and learning in South Africa was also covered. A qualitative research design and methodology were deemed appropriate to explore the challenges and strategies used by Foundation Phase teachers to enhance the English language proficiency of their learners. The research findings of the empirical investigation were presented in accordance with themes and categories that emerged from the data during the thematic analysis of the eight semi-structured individual interviews. The main concerns of the participants regarding the way to address challenges were presented. The complexity of this phenomenon pictured in my mind. The research findings lived up to my expectations and confirmed what was found in my literature study. Hence I came to realise that the experiences of the participating teachers were extremely important in reaching the conclusions of this research. The major research findings and meaningful issues came to light from the literature review and the empirical evidence. Finally recommendations are put forward for the consideration of Foundation Phase teachers, schools and the Department of Education (DoE) when dealing with the proficiency of their learners.

Thesis (M. Ed. (Education )) - Central University of Technology, Free State, 2014 / This study investigates mediation of learning in Grade 10 Business Studies. Mediation of learning is one of the roles that have to be fulfilled by educators in the teaching and learning situation. Learning theories that focus on teaching and learning provide insight about the study under investigation. Aspects such as teaching, learning, constructivism, mediation of learning, teaching strategies, teaching and learning through different learning theories and assessment for learning are dealt with. A qualitative research design is employed in this study. Data is gathered through observations of Grade 10 Business Studies lessons and questionnaires completed by Grade 10 Business Studies educators. Purposive sampling is used to sample the participants for this study. Ten schools in the Lejweleputswa district and ten Business Studies educators from these schools are sampled. Data is analysed qualitatively and emerging trends are reported on and interpreted. Observations in the study indicated that most Grade 10 Business Studies educators do not implement mediation of learning in their lesson presentations. Learners are mostly passive listeners in the classrooms. Most educators indicated that they implement mediation of learning in their lessons, although observations portrayed the opposite. Educators are in need of training to be successful mediators of learning. Conclusions and recommendations are made regarding mediation of learning in Grade 10 Business Studies classrooms.

Higher education landscape in South Africa could not escape the transformation which was necessary to ensure that South Africans receive quality higher education without any unfair discriminatory criterion. The 36 higher education institutions had to be merged and reduced to 21 and form a single coordinated higher education for the country. Tshwane University of Technology as a university with a multi-site institution has also resulted from this transformation agenda of the government. This merger is constituted by former Technikons Pretoria, Northern Gauteng and North-West. As a multi-site institution, managing other learning sites which used to be independent with their respective senior management structures became more challenging. An Interim Vice-Chancellor during the merger period appointed campus directors as an attempt to address challenges faced and discontent among staff and student. This study endeavours to describe and determine the roles of these Campus Directors in the institutional decision-making process of the University. / Public Administration / M. Tech.

In this investigation an attempt was made to determine the misconceptions that engineering students have of the idea of a limit. A comprehensive literature study showed that there are a number of common misconceptions that students normally form. The empirical investigation was done in two phases. A questionnaire on the idea of a limit was given to the students during the first phase. During the second phase six interviews were conducted. The findings were grouped according to the nature of a limit and students' views on the relationship between the continuity of a function at a point and the limit at that point. An analysis of these findings led to the identification of the misconceptions that these students have of the idea of a limit. / In hierdie ondersoek is gepoog om die wanbegrippe wat ingenieursstudente van die limietbegrip vorm, bloot te stel. 'n Omvattende literatuurstudie het 'n aantal algemene wanbegrippe aan die lig gebring. Die empiriese ondersoek het in twee fases plaasgevind. Tydens die eerste fase is 'n vraelys aan die studente gegee in 'n poging om meer te wete te kom van hulle begrip van 'n limiet. Die vraelys is opgevolg deur ses onderhoude. Die responsies is gegroepeer in terme van die aard van 'n limiet en studente se sienings van die kontinuiteit van 'n funksie by 'n punt en die limiet by daardie punt. Die analisering van hierdie responsies het die identifisering van 'n aantal wanbegrippe by hierdie groep studente moontlik gemaak. / Educational Studies / M.Ed.

Submitted in fulfillment for the requirements of the Masters Degree: Human Resources Management, Durban University of Technology, 2012. / Project Management for many years have been conducted using a traditional model with the focus being on time, cost and quality and its overall success on managing the organizations more effectively. Organisations are moving towards the use of a more modernistic approach where the focus is being extended to include cost, time, quality and linked to the strategic objectives, reward and recognition systems and building teams. The goals of the project must be communicated to all those who are involved in its implementation in order to ensure project success. Project managers who get people to want to do what they want by sharing their purpose, vision, and values also establish emotional and intellectual ties that result in sustained commitment. As the demand for project management increases, so does the use of tools and techniques. Project management offers a very structured approach to managing projects. The success of a project will be determined on the ability of the project manager to plan and develop a project, to implement, monitor and control and evaluate the project progress. DUT is faced with situation where there is an enormous demand by staff to participate in project management training. Many of these staff are directly involved in project management whilst others have requested this training as part of their capacity building drive. This study examines the perception of staff members who have attended the project management training with a view to making recommendations on how to improve project management at DUT. It also demonstrates the evaluation of the facilitator, the course content as well as the project management’s relatedness to the demographic profile of the University sample and presents and presents the perceptions of the respondents to the questionnaire. The method of research was largely quantitative and enabled comparison to be quantified. A self-administered closed-response questionnaire was adapted and used to obtain the information required. The study further investigated the staff members’ perception on project failure in respect of lack of user involvement, long timescales, failure to track the progress of projects, no formal change control, inadequately training project managers, poor leadership, cultural misalignment, poor planning and inadequate tracking and reporting. The dissertation makes recommendations on the project management course programme and the critical role of the project manager and the project team.

M. Tech. Business Information Systems / Having tools and resources that would enhance the performance of the learners would be of huge assistance to learners and their institutions. The increasing use of internet and technology has enhanced and transformed the conventional library resources into electronic resources. Utilizing electronic library resources helps learners to acquire information anytime and anywhere. Institutions that support the use of e-resources save significant amounts of money because the printing of materials are reduced. As a result, the use of e-resources by learners enhances their learning and their performance gets improved. The major objective of this study was to conceptualize a framework that will assist in successful electronic resources utilization. This was encouraged by the fact that the determinants of effective utilization of electronic resources are still not clearly expressed.

Teaching in the field of public health needs to employ a global perspective to account for the fact that public health problems and solutions have global determinants and implications as well. International university partnerships can promote such a perspective through the strengthening of cooperation, exchange, and communication between academic institutions across national boundaries. As an example for such an academic network in the field of public health, we introduce the International Public Health Partnership—a collaboration between a university in Germany and universities in India, Turkey, and Nigeria. Formed in 2005, it facilitated the exchange of information, fostered discussion about the transferability of public health concepts, contributed to the structural development of the universities involved, and promoted an intercultural dialog through a combination of local and distance learning activities. Although well accepted by students and staff, different obstacles were encountered; these included limited external funding, scarce own financial, time and personnel resources, and diverging regulations and structures of degree programs at the partnership sites. In the present article, we share several lessons that we learned during our joint collaboration and provide recommendations for other universities that are involved in partnerships with institutions of higher education or are interested to initiate such collaborations.

Objective Skin temperatures are known to increase cutaneous sensitivity. However, it is unclear whether the amount of improved sensitivity differs depending on the protocol of heat application. Therefore, this study aimed to investigate the effects of active (treadmill walking) and passive (infrared radiator) warming of the foot sole on vibration perception thresholds. Methods Sixty healthy and injury-free subjects voluntarily participated in this study. Vibration perception thresholds (200 Hz) and plantar temperatures were measured at the hallux and 1st metatarsal head. In experiment 1, warming and mechanically stimulating the skin was achieved by walking on a treadmill for 30 min. In a follow-up study (experiment 2), external plantar heat was administered via an infrared radiator (30 min). Results In both experiments, increasing temperatures led to increased plantar sensitivity. However, the amount of improved sensitivity was greater in experiment 1, although plantar temperature increases were lower compared to experiment 2. Conclusions Warming in conjunction with mechanical stimulation seems to have a greater potential to enhance plantar sensitivity compared to external heat supply only. Significance The possible influence of mechanical stimulation and warming towards superior plantar afferent feedback highlights its importance regarding human posture and fall prevention.

Background Migrants in many European countries including Germany tend to utilize preventive measures less frequently than the majority population. Little is known about the dental health of migrants as well as about their oral health behaviour, particularly in the adult population. The aim of this study was to examine differences in the uptake of annual dental check-ups in adult migrants and non-migrants in Germany. Methods We used data from the cross-sectional survey ‘German Health Update 2010’ conducted by the Robert Koch Institute (n = 22,050). Data from 21,741 German-speaking respondents with information on the use of dental check-ups was available, of which 3404 (15.7%) were migrants. Multiple logistic regression models were applied to adjust for demographic and socioeconomic confounders, including the place of residence as well as type of health insurance. Results Migrants were generally younger, had a lower socioeconomic status and showed a lower utilization of dental check-ups. The unadjusted odds ratio (OR) for utilization was 0.67 (95%-CI = 0.61–0.73). After adjusting for demographic and socioeconomic confounders the chance only increased slightly (adjusted OR = 0.71; 95%-CI = 0.65–0.77). Conclusions The analysis shows that migration status is associated with a reduced chance of attending dental check-ups, independently of demographic and socioeconomic factors. The influence of other factors, such as type of health insurance and place of residence had also no influence on the association. Migrants are exposed to different barriers in the health care system, comprising the patient, provider and system level. Further studies need to examine the relevant barriers for the uptake of preventive dental services in order to devise appropriate migrant- sensitive measures of dental prevention.

Alloying aluminum offers the possibility of creating low-density high-entropy alloys (HEAs). Several studies that focus on the system AlCoCrFeNiTi differ in their phase determination. The effect of aluminum on the phase composition and microstructure of the compositionally complex alloy (CCA) system AlxCoCrFeNiTi was studied with variation in aluminum content (molar ratios x = 0.2, 0.8, and 1.5). The chemical composition and elemental segregation was measured for the different domains in the microstructure. The crystal structure was determined using X-ray diffraction (XRD) analysis. To identify the spatial distribution of the phases found with XRD, phase mapping with associated orientation distribution was performed using electron backscatter diffraction. This made it possible to correlate the chemical and structural conditions of the phases. The phase formation strongly depends on the aluminum content. Two different body-centered cubic (bcc) phases were found. Texture analysis proved the presence of a face-centered cubic (fcc) phase for all aluminum amounts. The hard η-(Ni, Co)3Ti phase in the x = 0.2 alloy was detected via metallographic investigation and confirmed via electron backscatter diffraction. Additionally, a centered cluster (cc) with the A12 structure type was detected in the x = 0.2 and 0.8 alloys. The correlation of structural and chemical properties as well as microstructure formation contribute to a better understanding of the alloying effects concerning the aluminum content in CCAs. Especially in the context of current developments in lightweight high-entropy alloys (HEAs), the presented results provide an approach to the development of new alloy systems.
