- Description: This thesis investigates the feasibility of using gestures as a means of control for localizing three dimesional (3D) sound sources in a distributed immersive audio system. A prototype system was implemented and tested which uses state of the art technology to achieve the stated goals. A Windows Kinect is used for gesture recognition which translates human gestures into control messages by the prototype system, which in turn performs actions based on the recognized gestures. The term distributed in the context of this system refers to the audio processing capacity. The prototype system partitions and allocates the processing load between a number of endpoints. The reallocated processing load consists of the mixing of audio samples according to a specification. The endpoints used in this research are XMOS AVB endpoints. The firmware on these endpoints were modified to include the audio mixing capability which was controlled by a state of the art audio distribution networking standard, Ethernet AVB. The hardware used for the implementation of the prototype system is relatively cost efficient in comparison to professional audio hardware, and is also commercially available for end users. The successful implementation and results from user testing of the prototype system demonstrates how it is a feasible option for recording the localization of a sound source. The ability to partition the processing provides a modular approach to building immersive sound systems. This removes the constraint of a centralized mixing console with a predetermined speaker configuration.

- Description: When the apartheid government was in power universities in South Africa were segregated according to a race and language. After apartheid, the democratic government came into power and its vision was abolition of segregation. There was also equal and equity of access to public institutions which were set aside for certain people to have access to. Access to universities was equalized and students with different racial, social, cultural and linguistic backgrounds were allowed access to universities which they used not to have access to before. The students‟ access to all universities led to diversity within these institutions. Even though this was the case, there were no changes in the system prevalent during apartheid. English, for example, continued to be the language of learning and teaching (LoLT) while the numbers of students who speak languages other than English (LOTE) as home languages was also increasing. The Constitution of South Africa (Section 6, Act 108 of 1996) acknowledges the previous marginalization of indigenous languages in the country and encourages the development and use of these languages as official languages. The right of access to educational institutions, and accessing education in one‟s language, if that language is one of the official languages, is also encouraged by the Constitution. There are other supporting legislative documents such as the Languages Bill (2011), the Higher Education Act (1997) and the national Language Policy for Higher Education (LPHE) (2002) that support multilingualism, the equal promotion of the official languages as well as use of multiple languages in higher education institutions (HEIs) to support learning. The above mentioned policies and legislations may exist to ensure equality and equity, and even though HEIs have become heterogonous, that does not guarantee that the students enrolled in these institutions have equal access to knowledge offered by the HEIs in SA. This research uses the theories of languages and conceptualization; language and learning as well as language planning to show that the students‟ first languages in learning can assist to facilitate cognition. Terminology development, as part of corpus planning which is the body of language planning is introduced in this study in the form of bilingual glossaries as an intervention especially for students‟ whose mother tongue is not English as language used for learning at university for different disciplines tend to be abstract. The data for this research was collected from the 2014 first year students registered in the Extended Studies Unit (ESU) in the Humanities Faculty at Rhodes University. Research methods such as questionnaires, participant observations, interviews as well as content analysis were used to collect the data. These methods were used to look at the students‟ use and perceptions of bilingual glossaries as additional resource materials which can assist them in learning. A Political Philosophy I module offered by the Political Science department was used for this research. This thesis presents a model which can be used for the development of bilingual glossaries in order to facilitate learning. The thesis recommends the use of corpus extraction tools such as WordSmith Tools (WST) that can be used to generate and extract terms and illustrates the use of this tool by extracting terms from an English Political Philosophy textbook. These terms are defined and these are then translated into isiXhosa to provide a sample of the bilingual glossary. This glossary has been designed to illustrate how the bi/multilingual glossaries with terms and definitions can be developed in order for use by students to facilitate learning them. The study also presents a terminology list which consists of Political Philosophy terms that have been generated during the corpus extraction process. It is recommended that further research looks into the development of bi/multilingual glossaries using the suggested model so that the students who are speakers of LOTE can also be able to understand abstract terms which are used at university

- Description: This study analyses the effectiveness of community participation in service delivery. The area of study, the Chris Ham District Municipality (CHDM), is a Water Services Authority, responsible for ensuring access to water services (water and sanitation) by all communities within its jurisdiction. There are eight local municipalities within the CHDM. The objective of this study is to determine whether systems are in place in local government to promote participation by communities in service delivery projects and whether these systems are being utilised efficiently by the role-players concerned. The role-players in this research are people who are involved in community development programmes of the municipality (municipal staff in the relevant departments of the municipalities under study, the social facilitators, civil society organisations, ward committees, ward councillors, traditional authorities as well as the representatives of communities (Project Steering Committees) who are beneficiaries of the projects under study). The projects that are under study were selected from a readily available list of CHDM capital projects that appear in the 2003/2004 financial year funding plan and are running. The findings of the study at both levels (local and district) show that the municipal environment is not conducive to promoting community participation. This is linked to factors such as the structural arrangements, whereby the offices relevant for promoting community participation are not fully occupied, which provided evidence that community participation is not prioritised. There is lack of coordination of programmes within the local government spheres as well within departments of the DM and strategies for community participation have been found to be non-effective. At project level lack of community participation is linked to the utilisation of ward committees as the only mechanism for community participation regardless of its un-equal and party biased representation. This study therefore concludes that although the systems to promote community participation are in place, they are not effective.

- Description: Many rural South African people depend on natural resources for their survival. Wetlands provide some of those natural resources. These are presently are under pressure due to high demand, overexploitation and poor land management. The history of South Africa has been characterised by exclusion of local communities in the process of decision-making and general management of natural resources. Participation of all stakeholders is crucial for successful sustainable natural resource management. Various South African departments are engaged in a number of strategies for promoting meaningful participation of local communities. The South African laws promoting protection and sustainable use of natural resources incorporate democratic principles that require high level of participation from resource users, local communities in particular. Most of the participation techniques used are focused on satisfying political mandates and do not respond to the social context of the resource users. The aim of the study was to review the participation of stakeholders in the project of promoting the sustainable use and protection of the Lake Fundudzi catchment. The idea was to probe stakeholder interests more carefully, and to research tensions that arise in the participation process, using qualitative methodologies. Through the use of questionnaires, observations and document analysis stakeholders’ interests were identified to assess their influence in the process of participation of local stakeholders. The review of stakeholders’ participation in the Lake Fundudzi Project showed that stakeholders’ interests are crucial for meaningful local community participation, communication and education influence. They enable meaningful participation and empowerment. A multi-stakeholders approach enables stakeholders to share roles and responsibilities and the participation process offers an opportunity for local stakeholders to participate democratically in the Project. Power relations affect stakeholder participation, capital dependant participatory initiatives are likely to be at risk, participatory processes are likely to promote the empowerment and knowledge exchange amongst stakeholders, the views of local stakeholders are not always considered by outside support organisation and multi-stakeholder participatory approaches enable the initiative/activity/project to achieve its objectives.

- Description: Dopamine mechanisms in the central nervous system are important in the control of both normal and abnormal motor function. The recent observations in both animal and human studies, that melatonin, the principal hormone of the pineal gland, may have a role in the control of movement and the pathophysiology of movement disorders, have given rise to the concept that melatonin may have a modulatory influence on central dopaminergic neurotransmission. This study makes use of three animal behavioural models as well as a biochemical model of central dopaminergic function to further investigate the concept. Results from studies using the biochemical model, which investigated the effect of melatonin on dopamine and apomorphine stimulation of dopamine-sensitive adenylate cylase, suggest that melatonin is neither a competitive antagonist nor agonist at the D₁ receptor level, although the possibility of physiological stimulation or antagonism is not excluded. In behavioural studies, prior melatonin mg/kg administration (1 and 10 (8M) ip) inhibited apomorphine induced stereotypy and locomotor activity in normal rats, and apomorphine-induced rotational behaviour in 6-hydroxydopamine and quinolinic acid lesioned rats. The possibility that these results may have physiological significance is borne out by the observation that, under enviromental lighting conditions that are associated with raised endogeous melatonin levels, apomorphine- induced stereotypy and locomotor activity is attenuated. The general conclusion is that melatonin has an inhibitory influence on central nervous system dopaminergic function, suggesting therefore, that the pineal gland and melatonin may have a role in the pathophysiology and treatment of movement and behavioural disorders associated with dopaminergic dysfunction

- Description: The aim of this study was to examine the structure of the experience of gaining insight into oneself through perceiving another person. Such a one-to-one situation was selected in order to ensure a minimal level of complexity. The researcher conducted a pilot study in order to check whether people could relate such an experience in response to a long and difficult interview question. One female first year student responded from among a group of thirty to whom the question was posed. She was then interviewed. The data appeared acceptable. This was confirmed after the data analysis using the phenomenological-psychological method of textual analysis. The analysis showed that the subject, while comparing herself with the person whom she was with, discovered that she structured her life too rigidly in her attempt to meet the expectations of others. This discovery gave her the opportunity to restructure her approach to her world and to the others whom she had seen in only a narrow and abstracted way. Lengthier interviews were then conducted with a further six potential subjects. These were then transcribed. Two of those subjects, though, were found to have experienced insight through perceiving more than one other person. The data from the four remaining subjects were then analysed using the phenomenological psychological method. The researcher discovered that insight involves a clarity of perception which is achieved when the person becomes aware of clearly differentiated possibilities; these are revealed to him through his intensely reflecting on where he stands in relation to the other person whom he perceives, or in relation to alternatives revealed to him by the other. The polarities that are revealed allow the person to take up a new approach to his world, since the person discovers that his experience has revealed that he has been inauthentic in his muddled concern about others, and this gives the person a perception of truth that he was previously unaware of. These findings were dialogued with the writing of psychologists and philosophers who have written on the subject of becoming aware of oneself in relation to others.

The gradual absorption of the requirement of public benefit into the contemporary law is examined. Subsequent sections attempt to extract from the case law and to systematise the rules relating to the requirements of the defence of truth and public benefit, with a view to setting forth the circumstances in which the truth may lawfully be published. Section 2 deals with problems relating to proof of the truth of the imputation; Section 3 with the problem of when publication can be said to serve the public benefit. The final section seeks to examine the juridical basis of the defence and to relate it to recent developments in the law of defamation as a whole. Brief conclusions are then drawn and recommendations made.

- Description: In 1982, it was reported that one in every three students who fail at South African universities, do not pass because of experiences of excessive anxiety resulting from university examinations. A survey conducted amongst student counsellors and counselling services on all South African university campuses, revealed a deficiency of group and individual therapy for this phenomenon of examination anxiety. The cause of this deficiency, was found to be the already excessive demands made on the time of student counsellors. Noting a similar situation at Rhodes University, the present investigation was initiated, with the aim of developing an economical group counselling programme for test anxious students on Rhodes campus. Sixty-four Rhodes students (who identified themselves as test anxious) volunteered for this investigation. These Subjects were randomly assigned to one of four treatment programmes (each divided into two groups, where Group A, N=6 and Group B, N=7) and a wait-list control group (N=12). Three of the treatments featured multicomponent programmes, each offering a cluster of behavioural interventions centred around: Study Skills Training/Counselling; Systematic Desensitisation (Using individually-constructed anxiety hierarchies); Systematic Desensitisation (Using group-constructed anxiety hierarchies). Included in addition, was a single-component treatment, featuring cognitive modification: a component much favoured by local test anxiety counsellors. Given adverse reports concerning the efficacy of single component programmes, when contrasted with multi component treatments, the cognitive modification package was included as a placebo. A battery of measures was used to assess test anxiety and progress made by Subjects to assuage its debilitative effects . The measures included: (a) Six Self-report measures (including a treatment evaluation schedule and the maintenance of a diary of experience by each Subject); (b) Two measures of physiological reactivity, viz. pulse rate and finger sweat print; and (c) One 'observable' measure, that of academic performance. Using these measures, an assessment of the performance gains or losses by each of the Subjects, was made on three occasions: at pre-treatment, post-treatment and 6-month follow-up. In support of the a priori hypotheses, the systematic desensitisation and study skills multicomponent programmes, realised significant gains on all measures over both the placebo and control groups (with exception of the higher score achieved by placebo subjects over that of the study skills group, on the treatment evaluation schedule) . This finding confirmed the superiority of multicomponent programmes over those with only a single component. The systematic desensitisation programmes proved to be the most effective, as measured on self-report and physiological measures.

- Description: In 1982, it was reported that one in every three students who fail at South African universities, do not pass because of experiences of excessive anxiety resulting from university examinations. A survey conducted amongst student counsellors and counselling services on all South African university campuses, revealed a deficiency of group and individual therapy for this phenomenon of examination anxiety. The cause of this deficiency, was found to be the already excessive demands made on the time of student counsellors. Noting a similar situation at Rhodes University, the present investigation was initiated, with the aim of developing an economical group counselling programme for test anxious students on Rhodes campus. Sixty-four Rhodes students (who identified themselves as test anxious) volunteered for this investigation. These Subjects were randomly assigned to one of four treatment programmes (each divided into two groups, where Group A, N=6 and Group B, N=7) and a wait-list control group (N=12). Three of the treatments featured multicomponent programmes, each offering a cluster of behavioural interventions centred around: Study Skills Training/Counselling; Systematic Desensitisation (Using individually-constructed anxiety hierarchies); Systematic Desensitisation (Using group-constructed anxiety hierarchies). Included in addition, was a single-component treatment, featuring cognitive modification: a component much favoured by local test anxiety counsellors. Given adverse reports concerning the efficacy of single component programmes, when contrasted with multi component treatments, the cognitive modification package was included as a placebo. A battery of measures was used to assess test anxiety and progress made by Subjects to assuage its debilitative effects . The measures included: (a) Six Self-report measures (including a treatment evaluation schedule and the maintenance of a diary of experience by each Subject); (b) Two measures of physiological reactivity, viz. pulse rate and finger sweat print; and (c) One 'observable' measure, that of academic performance. Using these measures, an assessment of the performance gains or losses by each of the Subjects, was made on three occasions: at pre-treatment, post-treatment and 6-month follow-up. In support of the a priori hypotheses, the systematic desensitisation and study skills multicomponent programmes, realised significant gains on all measures over both the placebo and control groups (with exception of the higher score achieved by placebo subjects over that of the study skills group, on the treatment evaluation schedule) . This finding confirmed the superiority of multicomponent programmes over those with only a single component. The systematic desensitisation programmes proved to be the most effective, as measured on self-report and physiological measures. The superiority of group-constructed anxiety hierarchies over those individually-constructed was established. Study skills training helped Subjects to realise and maintain gains on the academic performance measure, although it took many of these subjects six months, before they had fully incorporated the study techniques taught, in with their own study habits. In discussion of the findings, the evident need to match test anxious students to programmes which "best suit" their characteristics, is presented, and solutions proposed. Weaknesses evident in the measuring instruments and research design, are also highlighted for discussion. As part of this experimental investigation, a discussion on the nature of test anxiety and its links with anxiety theory is introduced, together with a review of problems in measuring test anxiety; popular behavioural treatments used to relieve test anxiety; and a survey of test anxiety counselling on South African campuses. Advice for the therapist/counsellor, the academic, and the researcher, are posited in conclusion.
