This research was initiated as a result of the ever-evolving sophistication of criminal syndicates in their perseverance of organised crime and their use of electronic covert methodologies. Based on the researcher’s extensive managerial and operational experience, and on his unofficial observation of prosecutors, investigators and intelligence operatives, it became clear to him that there is a lack of evidence in court regarding serious and organised crime prosecutions. This can be attributed to the lack of use of investigative techniques, or investigative techniques being incorrectly used and/or a lack of knowledge regarding the use of investigative techniques. One such example of an investigative technique is surveillance or electronic surveillance. In this research study, the use and legality of electronic surveillance as a technique in the fight against organised crime, is discussed. Both national and international literature have been perused on the topic in question. Interviews were conducted with experienced former SAPS officers who were exposed to the use of electronic surveillance in the investigation of organised crime, as well as interviews with prosecutors, outlining the positive attributes of, as well as the shortcomings in, the use of electronic surveillance as an investigative tool in the investigation of organised crime. Surveillance or electronic surveillance has been in existence for a long period of time, but its usage or “know how” has been limited to only a few. The main purpose of the research is to highlight the importance of electronic surveillance as a covert technique in the investigation of organised crime. / Criminology and Security Science / M. Tech.

A Thesis submitted in fulfillment of the requirements for the degree of Doctor of Philosophy in Community Psychology in the Department of Psychology at the University of Zululand, 2007. / The major aim of the study was to determine whether broad-based initiatives, such as community based stigma reduction intervention programmes (later) based on the findings of the study, could have an impact on the uptake of HIV-testing and disclosure rate. The total sample comprised of 15 females and 15 males that were chosen from one of the support groups based at one of the selected Hospitals in KwaZulu-Natal Province. With the assistance of the hospital officials, the researcher was able to use the purposive sampling technique in selecting the respondents. From the themes, it became evident that people living with HIV and AIDS are faced with an important dilemma regarding whether or not they should reveal the HIV-positive status to significant others, in-depth interviews with the focus groups produced the following themes as accounts of emotional observations: isolation, social stigma, anger, revenge and depression. In the light of the findings of the study, a need arose for the establishment of an intervention programme aimed at addressing the common barriers associated with HIV disclosure. Community Psychology in particular, played a major role in shaping this study because of its action focus on groups. / National Research Fund (NRF)

A dissertation submitted in partial fulfilment of the Degree of Master of Library and Information Science (MLIS), in the Faculty of Arts at the University of Zululand, 2004. / The study defined customer care as an activity that allows customers to make direct contact with an organization to pass comments on products and their use. It also observed customer care as a customer service that seeks to acquire new customers, provide superior customer satisfaction, and build customer loyalty. The aim of the study was to investigate customer care strategies and services in academic libraries in tertiary institutions in KwaZulu-Natal. Two research assumptions were made. Firstly, it is assumed that academic libraries in South Africa do not have operational customer care strategies and services in place. Secondly, there is a relationship between poor information use and customer service and lack of customer care strategies and services in academic libraries in tertiary institutions. The study targeted 401 respondents, 307 students and 79 academic staff as well as 15 library staff. The study applied both quantitative and qualitative approaches and the population targeted was sampled by the use of stratified random sampling techniques. Three hundred and eighty six (386) questionnaires were distributed to both academics and students while interviews were conducted with the library management or unit and committee responsible for customer care. Statistical Package for Social Sciences (SPSS) was used to analyze data from academic staff and students. This software was selected because it is a user friendly data management and analysis package that can perform a variety of data analysis tests and presentation functions. Additionally, Microsoft Excel was used to analyze data collected from the library staff respondents. The study focused mainly on the problem areas, which depicts customer care policy and structures, customer care products and services, conducting of customer care, satisfaction of customers and strategies of customer care. It was discovered that some academic libraries do not have a formal policy on customer care in place. However, respondents were aware of and familiar with customer care policies in their libraries. Additionally, awareness and familiarity with information products and services was found to be known among library users. Furthermore, it was found that academic libraries do not have proper methods and strategies of customer care. Even those strategies that exist, are unknown among library users. It was further drawn out that library users are satisfied with information resources offered by their libraries. The study therefore, recommends that academic libraries should have a unit/person and committee responsible for customer care in place. In addition to that, library staff should attend workshops on customer care, to get formal training on how to deal with customers. It was observed that proper strategies and methods of conducting customer care must be implemented.

The purpose of this study was to look at how principals and educators managed and experience the implementation of Quality Assurance policies in secondary schools in KwaZulu Natal focusing on the bttegrated Quality Management System that is currently in place. This study was designed as a qualitative exploratory and descriptive survey. Data was collected in 2007 by visiting schools and conducting interviews with the principals and educators. School managers fell into two groups. One group was positive about Integrated Quality Management System and other group negative. Even though there were differences, all agreed that lntearated Quality Management System was good if it was to be introduced at a pace suitable to the educators. Educators preferred Integrated Quality Management System to systems that were not transparent. They then recommended that Integrated Quality Management System should not be linked to the educators' remuneration as this destroys what could be good about IQMS / Educational Studies / M.Ed.

Workplace violence directed at student nurses in training in psychiatric institutions is a significant concern as it negatively affects the quality of learning and causes the students to have a negative perception of nursing as a profession. The absence of scientific data describing the perceptions of student nurses about workplace violence and their clinical learning outcome motivated the researcher to conduct the study. Quantitative, descriptive research was conducted to explore the influence that workplace violence will have on clinical learning outcomes of student nurses who are studying psychiatric nursing at psychiatric institutions in KwaZulu-Natal, in South Africa. Data was gathered using a 71 question questionnaire, which was adapted from the one used by Hewett (2010). With the necessary permission from the health authorities, the campus principals and the nursing students, a group of 4th year student nurses (n=163) from 6 campuses of the KwaZulu-Natal College of Nursing (KZNCN) who have worked in psychiatric units for at least 3 months and longer participated in the study. The study highlighted the types of workplace violence encountered by student nurses, the effects of workplace violence on students’ academic performance and the barriers to the reporting of workplace violence encountered by the student nurses. The study revealed that there is a large amount of non-physical, some physical and a few incidents of sexual violence directed towards the student nurses at the psychiatric institutions, and that it has a negative impact on student learning. The recommendations emanating from the study support the idea of a shared responsibility between healthcare and education institutions and the focus is on preparing and equipping the student psychiatric nurses to confront, withstand and break the cycle of workplace violence. / Health Studies / M.A. (Nursing Science)

A qualitative study was undertaken in Pietermaritzburg to unveil the experiences and challenges of WLWHIV as perceived by social workers as well as to explore and describe the experiences of social workers in rendering services to these women. Explorative, descriptive and contextual research designs were employed for the research process. Purposive and snowball sampling techniques were utilised to recruit participants who met the set criteria. Face-to-face semi-structured interviews were conducted with thirteen participants. Data obtained were transcribed and analysed applying Tesch‘s eight steps (Creswell, 2009). Data verification was guided by Guba‘s model (Krefting, 1991). The findings revealed the existence of strained relationships between WLWHIV and their partners and ineffective delivery of social work services to WLWHIV. Based on the findings, it is recommended that specialised training for social workers on issues related to death and dying and services for children of WLWHIV be incorporated in the guidelines for social work practice / Social Work / M.A. (social Work)

The purpose of the study was to explore and describe the lived experiences of neophyte professional nurses working in ICU during their first year post graduation with the aim to discover strategies to support the nurse in critical care unit. An explorative, descriptive, interpretative qualitative design was conducted to uncover the nurse’s experiences. A purposive sampling was used which is based on belief that the researcher’s knowledge about the population can be used to hand pick sample elements. Data was collected through in-depth unstructured interviews and written narratives. Collaizi’s method of data analysis was used. The study findings revealed that neophyte professional nurses experienced difficulties and challenges in adjusting to the unit because of lack of mentors emanating from the shortage of staff. Nurses experienced mixed feelings regarding the relationship with colleagues in terms of support received. / Health Studies / M.A. (Health Studies)

Submitted in fulfilment of the requirements of the degree of Master of Technology: Biotechnology, Durban University of Technology, 2014. / Cyanobacteria contain phycocyanin a light harvesting pigment found to have numerous biotechnological applications, such as: a natural colorant in food and cosmetics, fluorescent tags employed in clinical and immunological research and also in therapeutic processes. Successful phycocyanin production depends on growth characteristics, ability to accumulate high quantities of the pigment, and an effective downstream process. Therefore, the aim of this research was to optimize the extraction method and production by determining the optimal cultivation conditions for phycocyanin producing cyanobacterium. This cyanobacterium was isolated from a hypersaline water body in Kwa-Zulu Natal, and subsequently purified using traditional streak and spread plate techniques. Different cell disruption techniques and a range of buffers were evaluated for the extraction of phycocyanin. The buffer concentrations and pH was subsequently optimized. Results showed that maximum phycocyanin was extracted when cells were suspended in 50mM sodium phosphate buffer (pH-7.5) supplemented with 10 % lysozyme and then disrupted using the freeze–thaw method at -20 & 4°C. The UV-Vis absorption spectral scan of the crude extracted pigments showed a peak at 620 nm. This corresponds to phycocyanin production. Unwanted proteins were removed using a 25and 50% saturated ammonium sulphate precipitation, followed by dialysis. SDS-PAGE showed two subunits with molecular masses of 19 and 20 kDa. These masses corresponded to phycocyanin α and β subunits. Furthermore, a food grade purity ratio (A615/A280) of 1.20 was achieved. The effects of various abiotic factors (temperature, light and pH) on growth and phycocyanin production of the Cyanothece sp. was investigated. Temperature ranging from 20-45°C and pH (5-10) was evaluated for 2 weeks. Cultures were then subjected to four photoperiods (24:0, 18:06 12:12 and 8:16 h light: dark) three light intensities (25, 75 and 125 µmol photons per m2 per –s) at varying wavelengths i.e. blue, red and green and Grolux light. Ideal conditions were observed at 35°C, 125 µmol photons.m2.s-1 of Grolux light for a 16:8 light and dark photoperiod. It was observed that the highest biomass and phycocyanin production was found to be at 35°C, temperatures below or above resulted in a decrease in both growth and pigment synthesis. Phycocyanin concentration changed in response to light quality and intensity. A significantly higher (p<0.05) phycocyanin yield was found when the culture was exposed to 125 µmol photons.m2.s-1 of Grolux light compared with the other three light conditions. Using Design of experiments, a series of fractional factorial experiments were carried out to optimize media components for pigment production. The final optimized growth medium was determined from a central composite design using response surface plots together with a mathematical point-prediction tool and consisted of 2g/L NaNO3, 0.06g/L K2HPO4, 0.12 g/L MgSO4.7H2O, 0.033 g/L CaCl2.2H2O, 100g/L NaCl, 12mL minor nutrients and 0.5 trace metal. A 72 % increase in phycocyanin was observed. This research revealed that this particular Cyanothece sp. shows great potential as a reliable source of phycocyanin.

Submitted in fulfilment of the requirements of the Master of Technology degree in Cost and Management Accounting, Department of Management Accounting, Durban University of Technology, Durban, South Africa, 2015. / Environmental degeneration, market pressures and stricter regulation and waste legislation has placed organizations under tremendous pressure to change their current processes and adopt cleaner production (CP) techniques and technologies. However, in countries like South Africa, CP implementation still remains low. In light of this problem, the government has made efforts to promote CP among industries by forming a support structure called the RECP (resource efficient cleaner production), as a strategy to encourage organizations to embrace this change and move away from the tradition end-of-pipe technologies towards CP technologies. This study is based on a case study of a paper manufacturing company in Kwadakuza, KwaZulu-Natal. The aim of this study was to use Environmental Management Accounting (EMA) to identify benefits of CP. Paper manufacturing consumes large amounts of natural resources and generates excessive wastes. Hence, the operational activities of paper mills have a negative environmental impact. However, the scope of this study was limited to the steam generation process and focused mainly on the efficiency of the current coal-fired boilers used in the boiler plant. The research methodology used in the study was both quantitative and qualitative involving triangulation. Data was collected by means of a questionnaire, semi-structured interviews and documentary review. The company uses old, obsolete boilers to generate steam. It had been discovered during a cleaner production assessment (CPA) of the process that the process uses large amounts of coal and generates excessive boiler ash (waste). This boiler ash also contains approximately 20 percent unburned coal present resulting in major losses to the company. Furthermore, the company has also experienced regular breakdowns during the year resulting in loss in production and high maintenance costs. Hence, it was concluded that the steam generation process was inefficient and that the boilers were not operating as per technological specification. However, management was unaware of the huge losses incurred due to raw material losses, more especially the coal used in the process. Environmental costs were also inaccurately calculated and thus underestimated. Hence, the ‘true environmental’ costs were not considered during strategic decision making. Over the last two decades, EMA has emerged as an important approach by organizations wanting to improve their environmental and economic performances. However, despite the many pilot projects conducted that demonstrated the positive impact that EMA has on an organization, EMA implementation remains slow and lagging in South Africa. EMA is an environmental management tool that traces environmental costs directly to the processes and products that are responsible for those costs, thereby highlighting problem areas that need to be prioritized when considering the adoption of CP. The literature review on the role and impact of implementing EMA and the benefits of adopting CP was presented to determine and outline views and findings of past researchers. Previous researchers identified that traditional costing systems did not adequately account for the actual environmental costs incurred by companies as much of these costs were hidden under overhead accounts. Hence, production costs were high, resulting in incorrect profit margins being set and ultimately impacting on company profitability. The main cause of this was that non-product output costs were added to production cost instead of being separately recorded as ‘non-product’ output. These costs are actually environmental costs as they represent waste. Material Flow Cost Accounting (MFCA), a tool of EMA, was considered as an appropriate method to implement to accurately calculate non-product output costs. MFCA made managers aware of the true magnitude of their losses and inefficiencies of current technology by increasing the transparency of non-product output costs (environmental costs). MFCA was further used to benchmark non-product output costs against technological standards and best available technological standards to highlight the economic and environmental benefits of adopting CP techniques and technologies. Based on the findings, one recommendation is that the company should consider restructuring their conventional costing system and adopt an EMA system instead. The use of an MFCA model had been suggested. This model was used by the Economy, Trade and Tourism industry in Japan to identify non-product output and improve efficiency of production processes. In addition, findings revealed that the company should implement CP techniques in the short-term to ensure that boilers are functioning according to technological specification. This will result in economic and environmental benefits for the company. However, greater savings potential is available in the long-term, by changing current technology and adopting state-of-the-art technologies. This would, however, require greater investment needs of the company to taken into consideration during strategic decision making.

Submitted in complete fulfillment of the requirements for the Degree of Master of Technology: Biotechnology, Durban University of Technology, 2012. / Immunomodulation using plants is of primary interest in scientific communities because it provides an alternative to conventional chemotherapy for a wide range of diseases. It is based on the ability of the plants to effectively modulate immune functions, thus being able to promote positive health and maintain the body’s resistance to infection. This research is aimed to evaluate the immunomodulatory potential of fourteen traditional leafy vegetables from Kwa-Zulu Natal, South Africa on human peripheral blood mononuclear cells (PBMC). In this study the methanolic and aqueous extracts were screened for lymphocyte proliferation using the MTT assay. The cytokine response was evaluated by measuring the secretion of interleukin 10 (IL-10) and interferon-gamma (IFN-γ) using the ELISA assay. The subpopulation of T cells viz., CD4+, CD8+, NK and B cells were measured by flow cytometry. Most of the methanolic extracts stimulated PBMC’s whilst a few suppressed lymphocyte proliferation. Most of the aqueous extracts were inactive. The methanolic extracts of Amaranthus hybridus and Centella asiatica stimulated PBMC’s and showed an increase in IFN-γ secretion and the CD8+ cytotoxic T cells and B cells. Thus, they induced the Tc-1 immune response and stimulated cell mediated immunity. The methanolic extracts of Asystasia gangetica, Bidens pilosa, Emex australis, Justicia flava Momordica balsamina, Oxygonum sinuatum, Senna occidentalis and Sonchus oleraceous and the aqueous extracts of Amaranthus spinosus and Asystasia gangetica, Ceratotheca triloba, Oxygonum sinuatum, Physalis viscosa and Sonchus oleaceous stimulated PBMC’s and showed an increase in IL-10 secretion and the CD8+ cytotoxic T cells and B cells. Thus, they induced the Tc-2 immune response and stimulated humoral immunity. Also, the methanolic extracts of Amaranthus spinosus and Ceratotheca triloba and the aqueous extracts of Bidens pilosa and Justicia flava increased both IL-10 and IFN-γ secretion and the CD8+ vii cytotoxic T cells indicating the stimulation of both the Tc1 and Tc2 cytokine profiles. The elevated secretion of IFN-γ and IL-10 caused by the extracts can be attributed to the CD8+ cytotoxic T cells and B cells. The findings of this study show that leafy vegetables hold promise as immunomodulatory candidates. They may enhance cell-mediated immune functions by a pro-inflammatory response whilst some can promote humoral immune functions by means of an anti-inflammatory response. Further investigation should be considered on the effect of the extracts on other immune parameters. / National Research Foundation
