This study sought to investigate and to record any recurring patterns in the form and communicative impact of Shona advertisements. Motivation to carry out the study came from a realisation of a growing interest in using the Shona language for advertising and the fact that very few studies have been done on Shona advertisements. For methodology, examples of Shona advertisements were qualitatively analysed using some communications and discourse analysis approaches of the speech act theory and text linguistics. A structured interview with advertising agencies randomly selected and a questionnaire on the impact of advertisements were also used. The findings of the research included that Shona was used in advertisements in order to reach out to the majority of the Zimbabwean population. In addition, Shona was also found to have been developed enough to handle formal issues like advertisements. This finding further shows that Shona advertisements reflect an instance of diglossia leakage from Shona L(ow) to Shona H(igh). Another finding is that Shona advertisements reflect some characteristics of the Shona speech community in form. These include code-switching, slang and word- division problems. An innovation in code-switching noted in some Shona advertisements is the use of three languages, namely, English, Shona and Ndebele in one advertisement. It was also established that everything about the elements of Shona advertisements communicate. For instance, the message may be visual, tactile and olfactory. It also emerged that the Shona commercial advertisements had a presenting and a hidden agenda at the same time. To achieve this the advertisements used persuasive techniques such as advertising claims, cultural hooks and personalities as spokespersons. It was also noted that most readers of advertisements do not interpret them up to the hidden persuaders but end with the direct meaning. On the other hand the Shona advertisements that gave information such as health issues have no hidden agenda. One recommendation made is that advertisements be read and studied to raise the level of awareness about the persuasive techniques used in order to distinguish between misleading advertising and those that give useful information. Some recommendations were made for future research such as carrying out similar studies of informal Shona advertisements, advertisements by n'angas/inyangas (traditional healers), prophets and political campaigns. / African Languages / M.A. (African Languages)

The main aim of this research was to explore lecturers’ and students’ perceptions of the effectiveness of teaching listening skills to English foreign language (EFL) students at three Ethiopian universities with the purpose of proposing guidelines and recommendations for effective teaching and learning of EFL listening skills. The research was prompted by a number of research projects which indicated that listening skills and the teaching of listening in the Ethiopian context were not effective resulting in students who are ill equipped for listening effectively. A mixed method approach was followed as a design for the empirical research study. A pragmatic research paradigm, using both quantitative and qualitative methods and then blending the two methods was employed. Quantitative data were collected from 72 lecturers and 158 students at three Ethiopian universities by means of close-ended questionnaires using a five-point Likert scale instrument. For the qualitative phase of the study data were collected by means of semi-structured interviews with lecturers and students. Observations of listening lessons presented in the classroom and in the language laboratory were done by means of completing an observation checklist and note-taking. These were used to triangulate data. The analysis of the data obtained by means of the questionnaires and the observation checklist were done using descriptive and inferential statistics. Qualitative data obtained by means of unstructured interviews (which were transcribed verbatim) were coded and divided into themes. The research findings indicated that the lecturers’ perceptions of the activities used during the pre-, while- and post-listening phases and the use of listening material were more positive than those of students and that females perceived the effectiveness less positive than males. The data obtained by means of interview questions confirmed what was found in the quantitative part of the study. Observations carried out in the three universities showed that the teaching of listening skills was mostly poorly done and that the listening material used was not suitable and did not interest students. The use of bottom-up and top-down strategies were found to be used inadequately in the teaching of EFL listening skills. The teaching methods and strategies used, as well as activities provided during each listening phase were found to be generally poor. A model for teaching EFL listening in the classroom was proposed in this study. Lecturers and students expressed their challenges in teaching and learning EFL listening skills and also made recommendations for best practices on how to improve the teaching and learning of EFL listening. These challenges and recommendations for best practices mostly centred around lecturer-related, student-related and institutional-related factors. This study has suggested recommendations pertaining to the lecturers, students, institutions of higher education, the Ethiopian Ministry of Education and schools. / Curriculum and Instructional Studies / D.

This research seeks to establish a methodology by which transitional justice strategies ought to be incorporated within the International Criminal Court (ICC) framework. The study is based on the situation in Uganda as an example of the state that has a situation and cases before the ICC. The aim of the thesis was achieved through the adoption of a combination of theoretical legal research and the non -doctrinal approaches. This research establishes that the primary responsibility to prosecute persons suspected of violating international law lies with the states. The importance of the concept of individual criminal responsibility, the idea that every person suspected of committing the most serious offences must be held accountable regardless of status. The principle of individual criminal responsibility is further developed with the creation of the ICC. This research clarifies that there are limitations in terms of what prosecutions can achieve during transitional periods; further, that trials in the ICC and national courts can be undertaken together with proceedings of the Truth and Reconciliation Commissions or indigenous mechasims. Such an approach will allow for confines of prosecutions to be addressed. Despite the existence of principles and institutional framework that are intended to ensure individuals are held accountable for the most serious offences of international concern, the majority of individuals are not held accountable. In order for the ICC to operate effectively it would need to seek to go beyond deterrence and retribution. This would require post – conflict states to devise transitional arrangements that compel with the ICC structure. Thus the research recommends that it would be better for judicial and non- judicial measures to be adopted in states that have cases before the ICC. Particularly Uganda must adopt the mato oput method formally as a tool to address the past human rights abuses in Uganda. All persons regardless of whether they have been granted amnesty or not must be held accountable under the mato oput measures. This implies all persons with exception to those that the ICC has issued the warrants of arrest against. / Public, Constitutional and International Law / LL. D.

The most contemporary approach to biodiversity conservation within South Africa is that of community-based initiatives, which seek to combine biodiversity conservation with socioeconomic development. As a challenge to the Western, science laden approaches to conservation there is an increasing need for community initiatives to reflect the values of local communities. Values of local communities and the management body, CapeNature, with regards to Driftsands Nature Reserve, Cape Town, were captured and analytically coded through the qualitative methods of interviewing and participant observation in order to develop a grounded theory and model. A discussion of the expressed values suggests that community-based conservation initiatives are doing little to include community values even though there is a large degree of agreement between these and corporate values. As such, it is questioned whether community-based conservation can be practised within an organisation which, due to procedures and protocols, is top-down in its approach. / Geography / M. Sc.

Listening comprehension and listening strategies plays a crucial role in the process of acquiring a language. This study aims to investigate to what extent the listening skill is practised in upper secondary schools in the south of Sweden. Research studies within the field of listening are few which indicates that the listening skill is not considered as essential in second language teaching as the other three skills: reading, writing and speaking. Previous studies indicate that teachers should educate students metacognitive awareness when teaching listening. The results summarize the teachers’ answers, reflections and attitudes conducted from semi-structured interviews. The analysis of the results focuses on the four categories distinguished from the teachers’ answers: Teaching Approaches, National Exams, The Individual Student and Metacognitive Awareness. Some of the teachers do not possess the knowledge of how to teach listening that develops students' listening proficiency. As a conclusion, the study shows that a hierarchy exists among the four skills to which teachers adjust to, and this may be detrimental in achieving educational aims.

Cities are highly unequal systems and rapid, top-down development is increasingly causing segregation between people of different socio-economic statuses through gentrification. In response, a bottom-up, more community centred approach is often proposed, yet this method also not without significant issues. In this thesis I investigate the role of the designer as a mediator, facilitator and translator between the top-down and bottom-up approaches to urban development. Using Grønland, Oslo as a case study, I start by gathering high-level research in order to understand the large-scale strategies that the municipality and private developers have for the area. In the second section, I undertake on-the-ground research in order to understand the everyday issues that people who live in, or use, the area face. In the final section I propose a research laboratory and makerspace that can activate the local community, providing the resources in order for everyday people to be able to have a positive impact on their city, in addition to gathering long-term, in-depth research on the area in order to influence the future of Grønland. This thesis is written as a working document that can, and should, be used by a wide range of people, from the municipality to local residents, and is designed to be added to as the project develops.

Site-based management (SBM) is recent restructuring initiative in schools. The study is carried out with the aim of investigating the extent to which teachers participate in site-based management in schools. The researcher assumes that teachers are sidelined in site-based management in schools. An extensive literature review provides a theoretical foundation of the study and exposes the nature of site-based management. The qualitative approach is used in the case study. Data are collected through interviews that were conducted between July and September 2004. The interpretive paradigm is used in data collection, analysis and interpretation. The collected data are analysed through inductive analysis. The major research finding is that teachers are marginalised in site-based management in schools and that school-based decision making is still largely in the hands of school principals. It is recommended that principals and SMT's improve their management and leadership styles in order to allow for real participation of teachers in decision-making to take place. / Educational Studies / M.Ed (Education Management)

The need for modern transportation systems together with the high demand for sustainable pavements under applied loads have led to a great deal of research on concrete pavements worldwide. Development of finite element techniques enabled researchers to analyse the concrete pavement under a combination of axle group loadings and environmental effects. Consequently, mechanistic approaches for designing of concrete pavements were developed based on results of finite element analyses. However, unpredictable failure modes of concrete pavements associated with expensive maintenance and rehabilitation costs have led to the use of empiricalmechanistic approach in concrete pavement design. Despite progressive knowledge of concrete pavement behaviour under applied loads, concrete pavements still suffer from deterioration due to crack initiation and propagation, indicating the need for further research. Cracks can be related to fatigue of the concrete and/or erosion of materials in sub-layers. Although longitudinal, midedge and corner cracks are the most common damage modes in concrete pavements, Austroads method for concrete pavement design was developed based on traditional mid-edge bottom-up transverse cracking introduced by Packard and Tayabji (1985). Research presented in this thesis aims to address the most common fatigue related distresses in concrete pavements. It uses comprehensive finite element models and analyses to determine the structural behaviour of concrete pavements under vehicular loads and environmental effects. Results of this research are supported by laboratory tests and an experimental field test. Results of this research indicate that the induced tensile stresses within the concrete pavement are significantly affected by vehicle speed, differential temperature gradient and loss of moisture content. Subsequently, the interaction between the above mentioned factors and concrete damage modes are discussed. Typical dynamic amplifications of different axle groups are presented. A new fatigue test setup is also developed to take into consideration effects of pavement curvature on fatigue life of the concrete. Ultimately, results of the research presented in this thesis are employed to develop a new guide for designing concrete pavements with zero maintenance of fatigue damage.
