Organisational Leadership / The purpose of this study is to determine which factors influence the formation of intention to adopt the NSFAS online financial application system at Tshwane University of Technology (TUT), and to identify barriers to adoption experienced by the NSFAS applicants at TUT. To achieve these objectives, the study utilised the Technology Acceptance Model (TAM) and the Ram & Sheth (1989) concept of barriers to model TUT NSFAS adoption patterns. To test this conceptual framework, a descriptive quantitative research survey approach was conducted. Data was collected through self-completion structured questionnaires from a sample of 644 TUT students in September 2015. SPSS Version 23 and STATA 12 were utilised to conduct descriptive and multivariate analyses including correlations and structural equation modelling respectively.

Thesis submitted in fulfillment of the requirements for the degree Master of Technologiae: Consumer Science: Food and Nutrition in the Faculty of Applied Sciences at the Cape Peninsula University of Technology Supervisor: Dr I Venter Co-supervisor: Ms L du Toit Cape Town September 2013 / Objective: To develop a valid and reliable test to determine the food knowledge of first-year students at a university of technology (UOT) in the Western Cape, South Africa. Design: Two preliminary food knowledge tests were developed covering the content domains, namely fruit and vegetables and fats and oils, as these topics attend to the areas of concern in the dietary intake of young adults. Both tests consisted of multiple-choice questions and incomplete statements compiled following the test item construction rules. The items of both tests were evaluated by experts in the field of food science and nutrition to ensure item content and face validity. Both tests were independently administered to two sample groups represented by knowledgeable students (having food-orientated subjects as part of their course) and less knowledgeable students (not having food-orientated subjects as part of their course syllabus) at a UOT in the Western Cape, SA for the item analysis and test construct validity and reliability determinations. The second preliminary test incorporating three response alternatives was developed as the number of items retained after the item analysis of the first preliminary test incorporating four alternatives was less than the envisaged number of about 20 items. Results: After the item analysis of the first preliminary test (n = 72 items) only 10 and 13 items were respectively retained after two administrations to two sample groups. The second preliminary test (n = 135 items) completed by knowledgeable (n=119) and less-knowledgeable (n=91) student sample groups delivered 74 items after its item analysis across the two content domains, namely fruit and vegetables (n=49) and fats and oils (n=25). The test was found valid, with a significant difference (p < 0.001) in the knowledge scores between the two sample groups (Mann-Whitney test, z = 9.74) and highly reliable (KR20 and Cronbach's alpha= 0.934). Conclusions: The test being a valid and reliable assessment tool can be used to determine the food knowledge of first-year students at a UOT in the Western Cape, SA, across the two content domains to establish if guidance and possible teaching is necessary to equip them with basic food knowledge to support them in their food provision. / Cape Peninsula University of Technology

In this master thesis project carried out on Scania’s interaction design department in Södertälje an evaluation of the technology gaze interaction has been done. The aim was to see if the technology was suitable for implementation in a truck environment and what potential it had. The work started by doing a context analysis to get a deeper knowledge of the research done on within the area related to the subject. Following the context analysis a comprehensive need finding process was done. In this process, data from interviews, observations, ride along with truck drivers, benchmarking and more was analysed. The analysis of this was used to identify the user needs. Based on the user needs the concept development phase was conducted. The whole development phase was done in different stages and started off by an idea generation process. The work flow was made in small iterations with the idea to continuously improve the concepts. All concepts were evaluated in a concept scoring chart to see which of the concepts that best fulfilled the concept specifications. The concepts that best could highlight the techniques strengths and weaknesses were chosen and these are Head Up Display Interaction and Gaze Support System.. These concepts focused on the interaction part of the technique rather than a specific function. Test of the two concepts were conducted in a simulator to get data and see how they performed compared to today´s Scania trucks. The result overall was good and the test subjects were impressed with the systems. However there was no significance in most of the cases of driving except for some conditions where the concepts prove to be better than the systems used today. Gaze interaction is a technology that is suitable for a truck driving environment given that a few slight improvements are made. Implementation of the concepts have a good potential of reducing road accidents caused by human errors.

In der 175-jährigen Geschichte der Technischen Universität Chemnitz nimmt die Technische Mechanik im Kanon der technikwissenschaftlichen Disziplinen eine exponierte Stellung ein, zählt sie doch zu jenen Grundlagenfächern, die bereits nach Gründung der Königlichen Gewerbschule im Jahre 1836 auf dem Lehrplan standen und im Fortgang der Schulentwicklung stete Ausformung und Bereicherung erfuhren. Getragen von einer Vielzahl von Lehrer- und Forscherpersönlichkeiten, die überwiegend auf langjährige praktische Erfahrungen in renommierten Betrieben und unterschiedlichen gesellschaftlichen Bereichen verweisen konnten, nahm das Fachgebiet bis zur Gegenwart eine bemerkenswerte Entwicklung. Heute stellt es einen wichtigen Eckpfeiler der Fachausbildung dar und wird nicht nur von den Studenten im Maschineningenieurwesen, sondern auch von zahlreichen tangierenden Disziplinen wahrgenommen. Erstmals wird diese historische Entwicklung aus verschiedenen Perspektiven zusammengefasst, indem sowohl die Entwicklung der Lehrinhalte als auch die Spezifik der jeweiligen Ausbildungsgegebenheiten eingehender beschrieben wird. Dabei finden Lehrende wie Lernende, aber auch Forschung und Entwicklung, wissenschaftliches Leben, internationale Zusammenarbeit und Publizistik gleichermaßen Berücksichtigung. Das Buch ist das Resultat langjähriger Forschungsarbeiten, die im Zusammenhang mit der Geschichte der Bildungseinrichtung und zu ausgewählten Themen der Wissenschaftsentwicklung unter der Obhut der Professur Wissenschafts-, Technik- und Hochschulgeschichte geleistet wurden, und als ein Beitrag zum Jubiläum »175 Jahre TU Chemnitz« zu verstehen. / During the 175 years history of the Technical University of Chemnitz technical mechanics has been one of the basic disciplines of the engineering sciences. From the Higher Vocational School`s foundation in 1836 it has been part of the curriculum and has experienced continuous enrichment and refinement. As a result of excellent work of a large number of academic researchers and teachers, most of them with a background at renowned industrial companies and in diverse social areas, this scientific field experienced a remarkable development. Today it represents an important cornerstone of the curriculum and is studied not only by mechanical engineering students but also by many others from neighboring disciplines. For the first time this historical development is presented from different perspectives, dealing in depth with the evolution of the different subjects taught and also with the specifics of the conditions of academic teaching. In this context, academic teachers and students, research and development, academic life, international cooperation as well as publications are dealt with. This book is the outcome of longstanding research pursued by the Chair of the History of Science, Technology and Higher Learning on selected topics of the history of science and academic education. It is a contribution to the 175th anniversary of the Technical University of Chemnitz.

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.

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 and Management / M. Tech.

Thesis submitted in fulfillment of the requirements for the degree Magister of Technology: Dental Technology In the Faculty of Health & Wellness Sciences At the Cape Peninsula University of Technology 2013 / Orthodontic archwires are made from different alloys. It is now possible to match phases of treatment with orthodontic archwires according to its mechanical properties. On this basis, the titanium molybdenum alloys (TMA) in its beta phase have an excellent combination of strength and flexibility when used as archwires to apply biomechanical forces that affect tooth movement. It has recently gained increased popularity in orthodontic treatment. There are, however, disadvantages associated with the use of orthodontic archwires, such as high surface roughness, which increases friction at the archwire-brackets interface during the sliding process. The surface roughness of dental materials is of utmost importance. Properties such as desirable tensile strengths, load deflection, hardness and low modulus of elasticity and resistance against corrosion & wear determine the area of the contact surface, thereby influencing the friction. The main object of this study was to improve the strength and surface roughness of the beta-titanium orthodontic archwires (β-Ti III) and timolium archwires (TIM), taking into account of retention of the archwires strength. The following tasks were performed. Layers of Zr were deposited on the β-Ti archwires and compared with the archwire strength before and after Zr deposition. The structure of selected archwires and its composition and surface roughness was investigated before and after Zr deposition, using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The force of selected archwires before and after deposition with layers of Zr by Hounsfield deflection testing was studied. Two commercially available orthodontic archwires were used in this study, namely, β-Ti III and TIM orthodontic archwires. The archwires were cut into 25 mm long specimens. In this study, the electron beam-physical vapour deposition (EB-PVD) technique was applied to deposit pure Zr (thicknesses of 5, 10, 25 and 50 nm) on selected archwires and the effects thereof were investigated using AFM, SEM and the Hounsfield deflection test. Results of SEM and AFM analysis and deflection tests showed significant differences between Zr-coated archwires compared with uncoated archwires. Zr-coated archwires (5, 10, 25 and 50 nm depositions) had reduced surface roughness compared with uncoated archwires. A high load deflection rate was exhibited by the coated β-Ti III archwires and a low load deflection rate was exhibited by the coated TIM archwires. There was a difference in load deflection rate between the coated and uncoated archwires. Deposition of 5, 10, 25 and 50 nm Zr on both types of β-Ti orthodontic archwires is recommended for even sliding mechanics due to resulting reduced surface roughness with a good load deflection rate compared with uncoated β-Ti orthodontic archwires.

Thesis in fulfilment of the requirements for the degree Doctor of Education in the Faculty of Education at the Cape Peninsula University of Technology Supervisor: Professor Rajendra Chetty Co-supervisor: Associate Professor Janet Condy November 2013 / In South Africa, the quality of teachers working in our current education system has been put under a looking glass by the Department of Education (DoE) (2006) since the systemic results, indicating national literacy and numeracy levels in primary schools, were issued. These results place South African literacy and numeracy skills far below those of many countries in the rest of Africa. This has been viewed by the South African school sector as one of the symptoms of the breakdown in the culture of learning in the education system in our country. As a result, the South African school system has been characterised as a ‘high- cost, high-participation, low-quality system’ Taylor (2008). Taylor (2008) concludes from his research that the challenges which undermine effective teaching and learning in South African schools include the quality of teacher knowledge and teaching practices. The relationship between teacher quality and teacher productivity is key to the development of a high-quality educational system. It is argued that teacher quality impacts greatly on student achievement, which, in turn, impacts on the development and transformation of that society. Rowe (2003) and Morrow’s (2007) key findings in their research on educational success indicate that ‘what matters most’ is the quality teacher. The historical and social change in South Africa has pioneered transformation with regard to curriculum change and has redefined the aims of teacher education in this country. Over the last few years we have been faced with a myriad of changes in policy frameworks that are supposed to guide change within the educational system, as well as within teacher education (Guskey, 2002:381-391). This study, therefore, aims to interrogate the missing links between teacher education institutions and pre-service teachers’ experience, while incorporating school and learner needs. Since quality is the critical factor, there is an urgent need to re-conceptualise how we can prepare a generation of teachers equipped to meet the demands of the 21st-century student. The key objective in this study, therefore, is the interrogation of the following components in the initial teacher-training programmes in South Africa: • Professional development and knowledge of teachers. • Delivery of that knowledge from a pedagogical perspective. • Quality of current teacher-training programmes. This research project is geared towards understanding the challenges that face final-year teacher-training students as they prepare themselves to enter the ‘real world of teaching’. The study cross-examines the quality of learning and teaching in higher education institutions, the pedagogy applied and the degree of its success. In order to examine the initial teacher-training programmes there was a need to interrogate: • students’ perceptions of the quality of their training; • lecturers’ responses to the quality of training provided; and • pre-service teachers’ notions of the quality of the ‘product’ they experience in the field during practice teaching and in their experience with newly qualified teachers. The search for an alternative pedagogy, which aims to promote the transformation and reconstruction of education in South Africa, has placed this research project within a conceptual framework of critical pedagogy, which holds the view that learning is self-generated and not just accessible. The theoretical underpinnings were derived from the works of Paulo Freire and Henry Giroux. This project is situated within an interpretivist paradigm and is qualitative in nature. A sample of four faculties of education, nationally, has been used in the project. Semi-structured interviews and focus-group interviews were used to collect data from all the fourth-year BEd students and their lecturers at each of the four universities, as well as from in-service teachers who host students during practice teaching sessions. The interview questions were concerned with the delivery of the teacher-training programmes and whether the needs of students were being met with regard to their training. Students commented on the development of the following areas: delivery of knowledge, acquisition of adequate teaching skills, and their readiness to enter the teaching field. The findings of this research indicate that students, lecturers and in-service teachers believe that many components within the current teacher-training programme need to be transformed. This could be attributed to, amongst others, the inadequate pedagogical practices used in knowledge delivery, lack of actual classroom experience, and the ineffective organisation and supervision of teaching practice which results in students feeling ill-equipped to enter the teaching arena. These impact the quality of teachers who are exiting the current system. Suggestions to improve the organisation of teacher experience, the on-going professional development of teacher educators, and mentorship ofteachers,as well as the development of recruitment and selection criteria for students wishing to enter teacher education are made.
