This dissertation reports an evaluation study which was done with an educational programme for Automotive Service Technicians which was adapted for South African conditions and derived from a programme used internationally, and originally developed in Schweinfurt, Germany in 2005. The programme was designed to answer to particular problems experienced during automotive driveline-component installations. Since the inception of this programme, ZF Germany had been training representatives from their different subsidiaries over the world on the essential elements of automotive driveline installation protocol. The representatives were trained to adapt the core programme in accordance with the particulars of the vehicle populations in each respective country, and the researcher has performed this task The aim of this research was to evaluate the effectiveness of one particular module known as “Guidelines to clutch replacement” with regard to bringing about the desired changes in knowledge, attitude and behaviour within the trainees. Previous anecdotal feedback from the industry had suggested that the programme had been helpful in the reduction of installation errors, but the extent of the successes and failures of the programme had been unknown until this study. The training department at ZF South Africa was tasked to design further training modules based on the findings of the module under study in order to establish the successes and failures of the core concept for improvement of successive programmes. The approach for this programme evaluation was utilization-focused which allowed the researcher to choose from and combine a variety of data collection strategies over the complete range of summative and formative evaluation approaches. However, in keeping with the stated aim of this study, this study had been limited to a summative inquiry by employing a quantitative data collection strategy at the hand of a quasi-experimental research design. This research report presents the findings of a one-day intervention programme that was offered to Automotive Service Technicians in the Gauteng area. The conceptual framework that was adopted for the research was based on the four level evaluation framework of Kirkpatrick (1998) with the first three levels having been empirically tested and the fourth level discussed on the basis of empirical information. Findings suggest that although the levels of knowledge-acquisition could not to be considered as high, behaviour modification had indeed been observed to be in alignment with the clutch-installation-protocol and almost all the respondents had adopted the protocol as their preferred way of executing clutch installations. In addition, most respondents found the programme to be pleasant and of a high utility value. Certain problems with the programme became evident, such as the pace having been too fast; printed hand-outs were not considered to have high utility value, and sensitivity to personal and cultural differences were found to be lacking. The low levels recorded for knowledge acquisition may be language related which possibly relates to the fast pace of the course. The research findings suggest that the course should be spread over two days instead of one day and be augmented with practical demonstrations and re-designed printed hand-outs. In order to effectively measure level four of the Kirkpatrick framework, criteria of concern should be negotiated with participating organisations in order to provide relative data for answering research questions on this level. Procedures for collecting data over the course of several years need to be established and agreed upon by all stakeholders for such data to be reliable and valid in the inclusion of a time-series study. Regarding a relatively simple programme such as the programme under study with programme objectives that have a predominant procedural-knowledge focus, the Kirkpatrick framework has been found to be effective and its procedures may be applied in other industry-based training programmes. An added academic contribution to the previous one is that the Kirkpatrick framework as utilised in this study has shown that the framework offers a high utility value for fast-paced short courses where contact time with trainees are limited and evaluation designs need to fit in with the practical limitations. The high utility value of the Kirkpatrick framework became evident in the findings of this study where transfer of learning had evidently taken place regardless of possible learning problems such as language barriers. / Dissertation (MEd)--University of Pretoria, 2014. / tm2015 / Science, Mathematics and Technology Education / MEd / Unrestricted

Beginning with the discovery of graphene, two-dimensional materials have amassed a strong interest. Like graphene, transition metal dichalcogenides (TMDs) can be coaxed into atomically thin sheets which have some impressive properties. Unlike graphene, TMDs also has a change in their electronic band structure causing an indirect band gap to a direct gap transition in its monolayer form. Additionally, these materials lose their inversion symmetry as a monolayer. These unique properties make TMDs a strong candidate for being used in optoelectronic and valleytronic devices. In order for these devices to be successful, the optical properties of TMDs must be thoroughly understood. Due to this class of material's strong Coulomb interaction, the optical properties are dominated by excitons, a quasiparticle made up of an electron-hole pair. Therefore, the success of these devices relies, in part, on understanding and manipulating excitons. One key parameter of excitons is their dephasing rate which characterizes the lifetime of the coherent superposition of two states (i.e. how the coherence decays which is caused by excitons interacting with their environment). In this work, two optical properties are investigated: (1) How the linear absorption of the TMDs A-exciton peak varies as the material increases in thickness. By looking at how the absorption varies by sample thickness, the interaction between emitters can be understood. Experimental results for the diamagnetic shift are presented which are used to determine the lateral excitonic size. Through theoretical calculations, based on the semiconductor Maxwell-Bloch equations, additional insight into the radiative coupling of the systems are obtained. (2) How the coherence prole of the exciton changes in the presence of an external magnetic eld and specic valley excitation. By varying the polarization scheme in the four wave mixing measurement, specic valley excitation can be selected, allowing for insight into the dephasing mechanisms. By applying an external magnetic eld, the energy levels of the electron and hole can be discretized and the corresponding eects on the system's coherence seen. In conjunction with time-dependent density function theory calculations and the experimental results, a deeper understanding of exciton dynamics and multi-exciton complexes was obtained. Finally, a new system is proposed in which complex spectroscopic techniques can be performed on micron sized samples as well as devices in the presence of an external magnetic eld at cryogen temperatures. This system will allow for the investigation of the optical properties of stacked monolayers (heterostructures) as well as devices.

Enligt nuvarande Läroplan ska eleverna ges möjlighet att utveckla språkliga förmågor och kompetenser för att möta upp vad samhället efterfrågar.

Research shows that it is possible when students participate in various literacy practices. In this study, a commonly used teaching material in the subject Swedish for pupils in grade three is analyzed. The study aims to contribute with knowledge of a) what textactivities are found in the teaching material, and b) what practices these can give rise to in teaching, in relation to the didactic questions what and how. Based on a socio- cultural perspective on learning, and with a literacy perspective on reading- and writingteaching, Prima Swedish 3 was analyzed. The study's results show that the learning tool creates literacy practitioners that support codebreaking. The result also shows that students are given the opportunity to practice their linguistic skills such as speaking, writing, reading, listening and talking in reading- and writingtactivities.

Today, companies are spending millions of dollars on cybersecurity, but compromised systems and stealing sensitive information are still huge problems. Protecting sensitive information has always been of vital importance. However, the struggle today is that digital information can be distributed to an endless amount of users, everywhere in the world. Security solutions today focus on role-based access control and "the principle of the least privilege". They can affect the productivity of employees, which is also a key aspect to be considered when it comes to security. Privilege users are the ones that possess the most permissions within a system and are, therefore, a significant risk. This thesis project is focusing on developing a solution that protects against security risks connected to the users with the most privilege. The developed solution resulted in a modular role-based access methodology, also adding the "four-eye principle" (4EP). By introducing an extra shield outside the standard API, sensitive commands sent unwittingly or wittingly by a privileged user can be discovered before compromising a system or leaking sensitive information. Introducing the "four-eye principle" in a secure proxy solution, a "third-party" user approves sensitive commands before reaching the intended system. The solution is developed in JAVA and is adaptable to different organisations by letting the system administrators choose an intended system, which policies of sensitive commands to apply and whom that needs to approve them. The concepts implemented in this prototype can be used in future industrial developments.
