Submitted in fulfillment of the requirements for the degree of Master of Health Sciences in Emergency Medical Care, Durban University of Technology, Durban, South Africa, 2017. / Introduction: Response times are considered to be one of the oldest and most popular indicators which are used to measure the efficiency of Emergency Medical Services (EMS), particularly to cases in which the patient’s condition is deemed to be life threatening. Purpose: To analyse emergency response times within the public sector Emergency Medical Services in KwaZulu-Natal and to compare these to the national norms. Methods: Using a mixed method approach, the study was conducted in two phases. The first phase involved collecting quantitative data for all the cases logged in the Umgungundlovu Health District Communications Centre over a period of one week (seven days). Phase Two involved the collection of qualitative data from focus group discussions which were conducted with three groups which had been identified. These groups included the communications centre staff, operational staff and supervisory staff. The aim of these focus group discussions was to identify factors that influenced response times as well as to propose strategies which would improve these response times. Content analysis was utilised to interpret the qualitative data which had been collected. Results: Quantitative data was collected from a total of 1 503 cases of which 680 were categorised as priority 1 (P1), 270 as priority 2 (P2) and 553 as inter facility transfer (IFT). The majority of the cases (895) had occurred in urban areas. A total of 406 cases were exempted as no patient was transported. The number of these cases was greater on days when the total case load was higher as compared to days with a lower total case load. The mean response time to cases in rural areas was 129 minutes and 110 minutes to cases in urban areas. All the time intervals were found to be longer for cases in rural areas as compared to those for cases in urban areas but with the exception of the EMD response interval. P1 cases had the shortest mean response times for both urban area cases (33 minutes) and rural area cases (95 minutes) as compared to the other case categories. Nevertheless, the national norm of 15 minutes in urban areas and 40 minutes in rural areas was not achieved in the majority of the cases. The mean Emergency Medical Dispatch (EMD) response interval was 41 minutes for P1 cases, 56 minutes for P2 cases and 96 minutes for IFT cases. The qualitative data revealed factors that impacted on the response times and helped to explain and account for the quantitative data results. Challenges regarding the availability of resources, including vehicles, staff and equipment, as well as the way in which such resources are managed, were highlighted. The high demand for services compared to the available resources was raised by the focus group participants with this high demand resulting in extended EMD response intervals. This was exacerbated by the overwhelming demand for IFT cases which are serviced by the same resources as emergency cases and which have a much longer mission time, thus delaying response times continuously. Exempt cases were also found to impact negatively on response times as, although operational vehicles are committed to these cases, services are not required. Inconsistencies with regards to case prioritisation and dispatch triage also emerged. External factors, including poor road infrastructure, lack of road names and house numbers, weather conditions and long distances between EMS bases, the patient or incident location and health care facilities were also identified as factors that resulted in extended response times. Strategies to improve the situation were explored. These strategies included the effective management of resources in order to ensure optimal availability, the introduction of a formal, computer aided, dispatch system, the adoption of demand pattern analysis and dynamic location/relocation models, standardised processes and procedures to guide all areas of EMS operations and the education of both the public and staff. Conclusion: South African EMS response time national norms for both rural and urban areas are unachievable under the majority of circumstances and, thus, they may be said to be unrealistic. Until these national norms, against which the efficiency of EMS in South Africa is measured, are revised, the service will be deemed to be incompetent. / M

Gastropods are one of the most diverse species groups in mangrove habitats, however, many of their specific roles in relation to ecological patterns and processes are currently largely unknown. The overall aim of this research project was to provide basic ecological information for key gastropod species from subtropical mangroves within a protected area. South African mangroves cover relatively small areas and are restricted to estuaries, these habitats therefore present unique opportunities and challenges to the species that occur in them. Three gastropod species, Terebralia palustris, Cerithidea decollata, and Melanoides tuberculata, all occur at their natural southernmost range limit within South Africa and were selected based on their prominence and occurrence in mangrove habitats of the iSimangaliso Wetland Park, a UNESCO World Heritage Site. Trophic linkages and resource partitioning, resource utilization rates, and ecological resilience were investigated respectively using: 1) a stable isotope (δ15N and δ13C) approach; 2) an experimental approach to quantify feeding dynamics (ingestion rate, consumption/digestion efficiency and grazing impact); and 3) a mixed-effects modelling approach to relate population responses to environmental variables. The diet of T. palustris was seasonally variable and a number of sources were incorporated by different sized snails, but their grazing impact on microphytobenthos was not significant. The results also indicated an ontogenetic shift in the dietary niche for T. palustris through robust partitioning of resources between different size classes. The diets of C. decollata and M. tuberculata were dominated by different primary resources as a function of where they occurred in the mangroves. Melanoides tuberculata consumed a wide variety of primary resources, a typical trait of an opportunistic generalist species. The ingestion rate of M. tuberculata was not dependent on the availability of microphytobenthos, and was highest when conditions were oligotrophic. The resilience of C. decollata was related to the tree-climbing behaviour of this species and its occurrence was best explained by sediment conductivity. These responses were considered in conjunction to what has previously been reported on the resilience of the mangrove trees. The results of this research project have provided new basic ecological information for all three gastropod species in this data-deficient subtropical region. This information can potentially be used in comparative studies for these species in other regions or in broader scale ecological studies. Terebralia palustris has recently experienced a range contraction along the South African coastline. This research project has shown that the diet of this species is highly variable and that food limitation and competition for resources should be considered as potential drivers of the local decline. Cerithidea decollata has in contrast expanded its distributional range in this region. This research project has shown that this species has a generalist diet and exhibits traits in relation to tolerance that are expected to have facilitated its expansion into temperate saltmarsh habitats that occur in dynamic estuaries. Melanoides tuberculata is a globally invasive species, and as South African populations are within its native range, ecological information from this region is valuable as it can be used to investigate the potential ecological effects following introduction into new habitats beyond the native range. Biological drivers have a significant impact on mangrove ecosystem functioning, particularly in relation to recycling and the retention of organic carbon generated through primary productivity. Understanding the ecological linkages that maintain ecological functioning and stability is therefore an important step towards conserving and sustainably managing threatened ecosystems such as mangrove forests.

South Africa is a country faced with immense challenges, such as poverty, as a result of high levels of unemployment. Poverty reduction has become an international phenomenon in view of high levels of poverty in most under-developed and developing countries. From 1994, the South African Government implemented various income generating projects amongst other programs aimed at alleviating Poverty reduction initiatives in South Africa mostly come from government and civil society structures, or non – governmental organisations (NGO) with the aim of changing the living standards of the poor so that they can at least meet their basic needs, such as food, shelter and clothing. This study seeks to explore the impact of income generating projects funded by the Department of Economic Development in the Sisonke District at UMzimkhulu, focussing on the efforts the Paninkukhu co-operative. The study is important because of the high levels of poverty. South Africa (SA) is a country faced with the challenge of poverty as a result of the high levels of unemployment. The research method chosen for the study included a qualitative and quantitative research approach where data was collected through the use of interviews and a questionnaire. The findings of the study indicate a need to provide training to the project members on capacity building.

Background: The World Health Organisation (WHO) initially recommended F100 formula in the treatment of severe malnutrition. F100 is made with full cream milk powder, sugar, oil and water with added minerals and vitamins. Ready to-use therapeutic food (RUTF) is a highly nutrient dense food enriched with minerals and vitamins, with a similar nutrient profile but greater energy and nutrient density than F100. RUTF has shown to be effective in the treatment of severe and moderate wasting and is associated with an increased recovery rate. In South Africa no studies are available on the recovery rate of children with severe acute malnutrition treated with RUTFs. Aim: To compare the recovery of clinically stable severe acute malnourished children, between the age of 12 and 60 months, treated with either F100 or RUTF as nutrition supplement. Methods: A randomised clinically controlled trial was performed. All children referred to Clairwood hospital with severe acute malnutrition (SAM), defined as a weight for height measurement of <70 percent of the median and/or < -3 SD below the mean WHO reference values or the presence of bilateral oedema were included in this study. Children were stratified according to age and gender and subsequently randomly assigned with randomisation tables to either the RUTF or F100 group. A total of 35 children were included in this study and data from 34 were analysed with 17 in each group. Results: Most children included in this study were between 12 and 18 months with boys in the majority. Both groups had a large percentage of HIV-infected children (70 percent in the RUTF group and 76 percent in the F100 group), with Tuberculosis (TB) co-infection in some of the children. One child died due to HIV related complications. The rate of weight gain was 7.77g/kg/day in the RUTF group and 6.11g/kg/day in the F100 group. There was no statistical significant difference established between groups (p = 0.46). The majority of children recovered within 21 days on the RUTF while the majority of children in the F100 group recovered after 6 weeks. There were no changes in height during the rehabilitation of these children. MUAC changes were observed with 92 percent having a mid-upper arm circumference (MUAC) of > 11.5cm after a 6 week intervention with RUTF and F100. Conclusion: RUTF resulted in better rates of recovery and can be used efficiently in rehabilitating children with SAM in a supervised facility setting. These preliminary results also point towards significant potential savings regarding hospitalisation costs since faster recovery has been demonstrated by children in the RUTF group.

The Indo-Pacific bottlenose dolphin (Tursiops aduncus) is a common top predator along the KwaZulu-Natal coast. There have been several dietary studies done on this species, most of which have classed this predator as an opportunistic feeder preying on the most abundant prey species in that area. In KwaZulu-Natal (KZN) a dietary study was carried out in 1990, but there have been no followup studies to examine potential changes in diet. A number of bottlenose dolphins get entangled in the shark-nets set off the KZN coast each year. These dolphins provide a valuable source of information about different aspects of the ecology of this population. The aim of this study was to examine the diet of bottlenose dolphins off the KwaZulu-Natal coast with particular emphasis on temporal change in diet composition. The contents of 102 stomachs of bottlenose dolphins (58 females, 44 males) accidentally caught in the shark nets between 1985 and 2010 were analysed, and compared to historical data from dolphins caught between 1975 and 1986. A total of 94 different prey species from 37 families (32 fish families, five cephalopod families) were identified in the stomach contents. Teleosts made up the most important prey group in numbers and weight constituting 84 percent and 67 percent, respectively, while cephalopods made up 15 percent of the number and 30 percent of the weight of the prey items. Multi Dimensional Scaling (MDS) indicated that there is no resource partitioning between males and females, but significant partitioning between juveniles and adults. Six prey species contributed more than 60 percent of the weight of all prey species in the diet. These species are the most important according to their calculated index of relative importance score and are, in order of importance: Sepia sp. (cuttlefish)., Pomadasys olivaceus (piggy), Trachurus delagoa (maasbanker), Scomber japonicus (mackeral), Loligo sp. (squid). and Pagellus bellottii natalensis (pandora or red tjor-tjor). When compared to historic data, no changes in the main prey species has occurred, but the piggy has decreased in importance (1976-1986 percent IRI=45; 2000-2010 percent IRI=22), while the maasbanker has increased (1975-1986, percent RI=4; 2000-2010 percent RI=20). Stable carbon and nitrogen isotope analysis performed on tissue from the teeth of T. aduncus caught in the shark nets between 1970 and 2010 showed that there has been no significant shift in trophic level (δ15N) or in primary prey source (δ13C) over this time. The isotopic signatures of different tissues from an individual were used to create a base line and describe the differences in tissue signatures. Blubber was found to be significantly different from skin and muscle, which were found to be isotopically similar. Skin from remote biopsies can therefore probably be used in place of muscle for isotopic studies of bottlenose dolphins, while caution should be taken when using blubber. Given that T. aduncus is still listed as “data deficient” by the International Union for the Conservation of Nature (IUCN), and the potential for climate change and expanding fisheries to alter the distribution and abundance of their prey species, long term dietary studies such as this are important in order for their effective conservation and management.

Since the first National Curriculum Statement matriculation results for 2008, there has been an outcry that rural secondary schools in KwaZulu Natal are lagging behind in terms of pass rate compared to urban and former Model C secondary schools. There are various contributory factors that are impacting on poor learners’ performance in rural schools. This study was specifically conducted in rural secondary schools of KwaZulu Natal. The reason was that there is few research conducted in rural schools, particularly with regard to teacher job satisfaction and professional development. There is therefore a belief that satisfied teachers produce good performance in their schools. Furthermore, it is also believed that satisfied and adequately developed teachers are the key to successful implementation of the grades 10-12 National Curriculum Statement. The study was therefore conducted to investigate rural secondary school teachers’ experiences of job satisfaction and their expectations of support to develop their competencies as curriculum workers. The research problem was investigated through the mixed methods research. The use of mixed methods research was to ensure that reliability and validity are addressed. The concurrent strategy of mixed methods research was employed. In concurrent mixed research methods, data is collected during the same phase. Data was collected from rural secondary schools of Umzinyathi, Ilembe and Empangeni districts in KwaZulu Natal. There were fifty rural secondary schools which participated in the study. Four hundred rural secondary school teachers completed survey questionnaires. Eighteen rural secondary school teachers participated in individual interviews. Only nine rural secondary schools were involved in observation and interviews. Research findings show that poverty was one of the major contributory factors that led to poor performance of rural secondary schools. Poverty and lack of adequate professional development programmes in rural secondary schools have negative impact in terms of teachers’ job satisfaction. Learners’ poor command of English in rural secondary schools contributed to their poor academic performance. Lack of support services, bad condition of roads and, long distances travelled by both learners and teachers contributed to teachers’ job dissatisfaction and learners’ poor performance. Rural secondary school learners were demotivated about learning, since they lacked role models in their communities. Rural secondary school learners were also undisciplined. They bunked classes. They carried weapons to schools. Rural secondary school learners also helped criminals to steal and vandalize school property. They smoked dagga inside the school premises. Moreover, research findings indicate that rural secondary school teachers were not involved in school decision-making processes. School management teams were the only structure making school decisions. Growth opportunities for teachers were not fairly provided to them by their principals. Schools governing body chairpersons and principals were abusing the teacher promotion process since they were biased. They only promoted their friends and relatives and sometimes they were bribed by candidates. The latter findings contributed to teachers’ job dissatisfaction. Further findings indicate that there were teachers who were teaching subjects for which they were not qualified. Some heads of department were supervising subject streams that were outside of their specialization since the school post-provisioning norms (PPN) was small. Rural secondary school principals possessed inadequate grades 10-12 National Curriculum Statement expertise. Integrated Quality Management Systems was unable to develop teachers for effective grades 10-12 National Curriculum Statement implementation since it was not implemented accordingly in rural secondary schools. Clusters were effective strategies to develop teachers in rural schools although geographical isolation of school was their main challenge. The recommendations of this study are that RSSs must be fully supported by the KwaZulu Natal Department of Education. All roads to schools must be repaired in time. Decent teacher accommodation must be built inside schools with security guards to look after teachers’ safety and their property when they are away. Recreation venues/centres must be established in rural areas to relieve and address teachers’ stress and boredom. The KwaZulu Natal Department of Education must ensure that all schools have libraries, laboratories and computer classes. The Department of Education must also fully recognize postgraduate qualifications such as honours, master’s and doctoral degrees to retain highly qualified teachers in rural secondary schools. Teachers must be promoted on merit rather than on friendship or relationship.

Submitted in partial fulfilment of a Master's Degree in the Department of Educational Planning and Administration at the University of Zululand, 2006. / The South African School's Act No. 84 of 1996, calls for transformational leadership in schools. Principals are under obligation to comply with the stipulations of the act, which compel them to work in democratic and participative ways. School management and governance must be inclusive with roles and responsibilities defined for educators, parents and learners. Jointly they must ensure accountability, transparency in the delivery of quality public education. This study reviewed literature on the role of principals as change managers in schools. The Department.of Education (1999: 46-48) wishes to promote a culture of teaching and learning where respect is commanded through stature rather than status and the impetus of educational service delivery is about development rather than delivery of expertise. Principals are being called upon to manage and implement transformation that will embrace and give practical application to these ideals. In order to test principals' commitment to and effectiveness in change management, an empirical investigation was conducted in schools in the Umbumbulu Circuit of the Ethekwini region of KwaZulu-Natal. Findings of the study led to the following conclusions: • principals are grappling to implement changes in schools; • there is a lack of change management expertise in the ranks of principals; • principals resist change instead of initiating and implementing change. Several recommendations were drawn from the study. These included: • The development of a greater number of workshops to capacitate principals to manage change. • More concrete incentives are to be devised and implemented to motivate principals to accept change and implement policies that mandate change. • Effective change management strategies must be made explicit and brought to the attention of principals as concrete measures that can be used to facilitate change.

MA (Sociology) / Department of Sociology / This study aims to investigate the socio-cultural influence towards the risky sexual behaviour of adolescents in eSikhaleni, in context of the prevalence of HIV/AIDS epidemic. The study will adapt a qualitative approach. It is an explanatory study goes beyond simple description to model empirically the phenomenon under study. The participants were drawn from two categories. The participants for the key informant interviews were selected purposively and they include community leaders, high schools principals and life orientation teachers. The adolescent’s learners were selected using a snowball sampling technique. Data was analysed thematically, matrices were created using to content thematic analysis. The responses were grouped thematically. Broad categories were then generated to differentiate and explain the thoughts expressed by the respondents. Invitations to participate on the study were sent to respondents by submitting informed consent electronically and in person. When participants completed the structured interview they were not required to reveal their personal or contact details. The findings of the study reveals that risky sexual behavior amongst adolescents learners is as a result of a number of factors which include the diminishing role of parenting, death of morality in society, poverty and deprivation just to name a few. The recommendations advanced speak to the need for government to have a multipronged strategy of resolving the problem.

A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Arts in Communication Science at the University of Zululand, 2002. / In this thesis I present the results of a literature study, followed by an empirical surrey, regarding the leisure time activities of Zulu adolescents in rural and semi-rural areas of KwaZuhi-Natal along the northeastern seaboard of South Africa. My findings contextualise the above group's socialisation with regard to leisure time activities, home chores, school homework, school sports activities, communal tribal activities and local community events. I document and explain a variety of neighbourhood activities, including ones played during impromptu-organised neighbourhood get togethers. They include games ranging from the mundane to the innovative. I also analyse the annual Zulu Reed Dance Ceremony as a symbolic female rite of passage to womanhood, and various activities that serve as male rite-of-passage activities to manhood. My major finding is that all forms of social behaviour of Zulu rural adolescents — including their leisure time preferences — are informed by a coherent value-belief system in which religious beliefs play a central integrating role.

Submitted to the Faculty of Arts in fulfillment of the requirements for the Degree Master of Arts in the Department of Criminal Justice at the University of Zululand, South Africa, 1999. / This investigation entails a study of motor vehicle theft and hijacking in KwaZulu-Natal and Western Cape for the period of 1 January till 31 December 1995. The present study is empirically founded and for this purpose an information schedule has been implemented to capture data from police case dossiers for statistical analysis and description. Data forthcoming from a previous Honours study in the Westem-Cape have also been incorporated for comparison purposes. The sample consists of 1331 cases of motor vehicle theft and hijacking in KwaZulu-Natal, while 372 cases in Western Cape were included in this investigation. Key findings emanating from this investigation are as follows: (1) White male victims in the age category 31-35 years were the most victimised through motor vehicle theft and hijacking in both Provinces. (2) The profile of the average offender of motor vehicle theft and hijacking comprises an unemployed African male person between 21-40 years. (3) The temporal frequency indicates that most people in KwaZulu-Natal were victimised during March, August and October, while October, September and May caused the most suffering for victims in the Western Cape. Thursdays and specifically early mornings in KwaZulu-Natal seems to be the most popular for motor vehicle theft and hijacking. In the Western Cape this tendency peaked in the early mornings of Fridays. (4) Toyota followed by Mazda, Nissan / Datsun and Ford sedan vehicles were the most popular objects for motor thieves and hijackers. The following recommendation have been made: (1) Greater community involvement in the prevention of these types of crime has become inevitable. In this regard empowerment of local communities through Community Police Forums could play an important role. Such involvement could stimulate greater crime awareness among the community. Shared responsibility as far as the security of people and their property is concerned, could positively influence successful order maintenance. (2) Security measures which including the installation of anti-theft devices should be prioritised by the public. (3) Specialised Vehicle Theft Units should, in the light of the low percentage motor vehicle theft cases referred to courts, be more efficient - considering the availability of modern technology. (4) Police involvement in crime syndicates should receive serious attention and, were applicable, be totally eliminated (5) Progress without research is futile. Greater liaison between the police and tertiary institutions (Criminology departments and the Technikon SA) will do much to stimulate scientific research in the interest of successful policing.
