- Description: The elderly prefer to live independently despite vulnerability to age-related challenges. Constant monitoring is required in cases where the elderly are living alone. The home environment can be a dangerous environment for the elderly living independently due to adverse events that can occur at any time. The potential risks for the elderly living independently can be categorised as injury in the home, home environmental risks and inactivity due to unconsciousness. The main research objective was to develop a Smart Home Environment (SHE) that can support risk and safety monitoring for the elderly living independently. An unobtrusive and low cost SHE solution that uses a Raspberry Pi 3 model B, a Microsoft Kinect Sensor and an Aeotec 4-in-1 Multisensor was implemented. The Aeotec Multisensor was used to measure temperature, motion, lighting, and humidity in the home. Data from the multisensor was collected using OpenHAB as the Smart Home Operating System. The information was processed using the Raspberry Pi 3 and push notifications were sent when risk situations were detected. An experimental evaluation was conducted to determine the accuracy with which the prototype SHE detected abnormal events. Evaluation scripts were each evaluated five times. The results show that the prototype has an average accuracy, sensitivity and specificity of 94%, 96.92% and 88.93% respectively. The sensitivity shows that the chance of the prototype missing a risk situation is 3.08%, and the specificity shows that the chance of incorrectly classifying a non-risk situation is 11.07%. The prototype does not require any interaction on the part of the elderly. Relatives and caregivers can remotely monitor the elderly person living independently via the mobile application or a web portal. The total cost of the equipment used was below R3000.

- Description: This dissertation wants to understand the church history regarding the divide which resulted in the so called fundamentalist and the liberal movements in the church being birthed in identifying the reasons for the conflict between the aforementioned groups. It then presents principles of conflict transformation and management in order to understand and to help transform and manage potential confrontational situations between the aforementioned groups effectively. It further propose alternative interpretations to potential conflict-generating Bible texts by extrapolating new information from those texts in order to stir the potential of birthing a second naïve love for the discredited texts by offering new meanings to those same texts. Unfortunately, this objective can’t effectively be measured within the scope of this dissertation, but will nevertheless remain as an objective of hope.

Exploitation of non-living marine resources within national jurisdiction in East Africa

- Description: This dissertation involves an analysis and discussion of the legal regime governing the exploitation of non-living marine resources within national jurisdiction in East Africa. This is in light of the relatively recent offshore oil and gas discoveries off the coasts of Mozambique and Tanzania which have resulted in offshore exploration activities along the Western Indian Ocean (including the Red Sea) in pursuit of these hydrocarbons. Before delving into legal analysis and discussion, the dissertation departs by providing background on the 1982 United Nations Law of the Sea Convention (LOSC)2 which is the international legal regime governing maritime spaces and the contributions made by, inter alia, East African coastal States to bring it about. From here, the dissertation ventures into an analysis and discussion of the legal zones claimed by East African coastal States within which exploitation activities may occur. This part of the discussion involves, among other things, an in depth analysis of the practices of East African coastal States as far as establishing maritime zones in terms of international law. The dissertation then proceeds to discuss which East African coastal States have delimited their maritime zones where they overlap with neighbouring States with adjacent and/or opposite coasts. The discussion highlights which States, in terms of international law, have clearly defined the ambit of their maritime jurisdiction by establishing a delimitation boundary where claims to maritime zones overlapped. This part of the dissertation also discusses which States have not delimited their overlapping maritime zones and the reasons for the lack of delimitation. Following this, the dissertation moves on to discuss the LOSC provisions applicable to exploiting non-living resources, and analyse whether the laws of East African coastal States that pertain to exploiting these resources adequately give effect to LOSC. Finally, in light of the above analysis and discussions, the dissertation moves on to establish if whether or not the legal infrastructure of East African coastal States is adequate for exploiting non-living resources within their national jurisdiction. Generally, the findings reflect favourably on the legal framework of East African coastal States. However, the pressing issue is the practices of some States in respect of claiming certain maritime zones and where necessary, not delimiting these zones. This results in uncertainty as to the maritime jurisdiction of a coastal State, especially with resources such as oil and gas which may straddle across boundaries. Moreover, it creates conflict and as such, threatens peace and security in the region as well as stunt economic and socio-economic development. As such, this dissertation, on the one hand, reflects the advancement of East African coastal States from contributing towards the adoption and coming into effect of LOSC, as well as giving effect to it domestically as far as exploiting non-living resources within national jurisdiction is concerned. On the other hand, it highlights the work that lays ahead for East African coastal States in order for them to fully enjoy their right.

Eating disorders, body image and weight control life orientation teachers' knowledge, attitudes and behaviours

- Description: The apparent increase in the incidence of both anorexia nervosa and bulimia nervosa worldwide has resulted in a surge of interest in effective treatment, prevention programmes and health promotion. Health promotion and the primary prevention of eating and body image problems among young people, and in particular adolescents, is emerging as one of the most desirable achievements in contemporary health and nutrition education. Eating disorders usually have their origin during the teenage years, and as such, high schools provide useful sites for the implementation of prevention programmes. Educators can play an important role in the prevention of eating disorders and act as socialization agents who either reinforce or buffer the dominant societal discourses that shape young women’s views of themselves. There are calls, however, for caution in the design and implementation of school-based eating disorder curricula as school educators may inadvertently do more harm than good. It has also been suggested that female educators, as other women, are likely to possess a degree of normative discontent with their body shape and size, and that this dissatisfaction and negative beliefs about food may be unknowingly transferred to the learners within their care. The current study used an exploratory, descriptive research design to investigate the knowledge, attitudes and behaviours related to eating disorders, body image and weight control of a group of Life Orientation educators. A biographical questionnaire, a questionnaire designed for the purposes of the current research and two standardised paper-and-pencil questionnaires, namely the Body Shape Questionnaire (BSQ) and the Eating Attitudes Test (EAT), were administered to 50 female Life Orientation educators in the Nelson Mandela Metropole. A non-probability purposive sampling technique was used in the selection of participants and descriptive statistics were used to explore and describe the data. The results of the current research study indicated a lack of knowledge in those Life Orientation educators assessed regarding eating disorders and healthy diet. The results also indicated inaccurate knowledge amongst those educators assessed regarding effective and safe teaching practices of eating disorder pathology. The results of the two standardised questionnaires reflected an internalisation of the dominant societal ideals regarding weight and body shape, with 18% of the sample xi demonstrating attitudes and behaviours that could be indicative of eating disorder pathology of either clinical or subclinical proportions. Suggestions were made regarding future research and the need for further training of Life Orientation educators. Finally, the limitations as well as the value of the research were outlined.
