It is projected that by 2025 three-quarters of the world’s population will live in the coastal zone. This is an alarming statistic, with a consequently significant impact on small coastal towns and the adjacent marine environments. Developing communities within the coastal zone of South Africa have proved to be a significant pollution source of storm water. Studies have shown that storm water that is deposited in the ocean will be trapped in the near shore marine environment causing poor seawater quality over a large distance. Furthermore, this can pose a significant threat to the health of recreational users and important marine ecosystems. In Jeffreys Bay storm water quality is thought to pose a threat to the maintenance of the international Blue Flag status for its beach. The aim of the current project was to investigate the main sources of storm water and subsequent marine pollution at Jeffreys Bay and to develop an appropriate management strategy using the integrated environmental management framework. In order to achieve this objective, it was also necessary to determine the current quality of water at various points within the catchment and near shore marine environment. Even though the storm water was found to be severely contaminated no evidence existed for a negative impact on the marine environment. None the less, a precautionary approach was adopted and a risk assessment employed in order to consider potential impacts on the marine and aquatic environment, human health and socio-economic welfare within the town. Significant sources of storm water contamination included grey water, domestic solid waste disposal and informal ablution. These significant aspects were investigated further and it was found that solid waste management in the catchment was poor with significant quantities of waste, primarily (76%) from domestic sources, being disposed of illegally. A study of sanitation management showed inadequacies where up to 58% of the residents from the informal settlements disposed of their grey water into open spaces. The ratio of residents to toilets in these areas was 28:1, therefore supporting the outcome of the risk assessment. Due to the fact that all the significant aspects were related to anthropogenic waste, an integrated waste management plan (IWMP) was developed that would not only facilitate the reduction of pollution of storm water, but would also allow for sustainable community-based development.

This study is about assessing security measures in the hotel industry in Gauteng Province, South Africa. The researcher divided Gauteng into five regions (Mogale City; Tshwane; Central Johannesburg; Ekurhuleni; and Sedibeng). The researcher adopted the qualitative approach where one-on-one interviews were conducted with the participants. There were 20 hotels that were selected to participate in the study. From the 20 hotels, where only one participant from each was involved, the researcher conducted one-on-one interviews with twenty (20) Security Managers or anybody who was responsible for the security functions at senior level at the hotels. A semi-structured interview schedule with probing questions was used as a guide to obtain comprehensive information about security measures from the participants. Random sampling approach was used in the study. From the population of 70 hotels in Gauteng, where the sample of twenty (20) was derived, was the group within which the researcher was interested in for obtaining data. Since Gauteng Province is huge, the researcher only conducted research within the four metropolitan areas consisting of Johannesburg, Mogale City, Tshwane and Ekurhuleni. The aims and objectives of the research study are as follows: • Outline the nature of business that hotels are engaged in; • Investigate if there are security policies and procedures as part of effective security component; • Examine what important assets need to be protected at hotel facilities; • Uncover the risks facing assets in the hotel facilities; • Determine what incidents of loss took place in the hotel facilities; • Examine what assets are mainly targeted by perpetrators at hotels; • Uncover the profile and modus operandi of hotel perpetrators; • Examine the effectiveness of security measures and systems that are put in place at hotels; • Explore if security systems are integrated at hotels; • Determine the frequency of conducting risk assessment at hotels; • Check if pre and post-employment screening is conducted for security officers at hotels; • Find out if the guests inquire about security measures when making reservations; and • Find out how guests feel about security at the hotel facilities. The study revealed the following: • Hotels are business entities which attract different types of guests, nationally and internationally. Different services that are offered at the hotels which make hotels the main choice of destination to the guests are: accommodation for sleeping, leisure, and work commitments such as workshops or conferences. The study also revealed that most of the clientele comes from the corporate sector. • There are basic security measures in place in the hotels. These range from security policies, security procedures, physical security (for example, technological security such as Close Circuit Television (CCTV) surveillance system, adequate security lighting, security personnel (contract or in-house), alarm systems, armed response, access control systems and security fence or walls). The security measures were also appeared to be put in place in accordance with the location of the hotel. If the hotel was surrounded by other business areas, the level of security was more focused in the inner security layer. If the hotel was standing alone, the different security layers (the inner security layer, the outer and the middle security layers) were adequately protected. • Hotels are faced with different risks such as theft, prostitution, murder and assault, among others. Theft however was found to be across the board; for example, people were stealing the hoteliers’ property or the guests’ property. • Prostitution was found to be prevalent at hotels. Prominent people from political arena, corporate environment and other guests were interested in the prostitutes. Prostitutes were said to have their own modus operandi of using drugs to their prospective clients and then rob them of their money and belongings thereafter. • Most of the assets which are targeted by hotel perpetrators were found to be: guests/hotel money, hotel goods, guests’ cars, goods in guests’ cars, televisions, home music systems and mobile devices such as laptops and cell phones. • The profile and modus operandi of hotel perpetrators. • Security assessments are conducted at hotels so as to figure out what security risks are facing the hotels. • Hotels need to be protected at all times against criminality as it tarnishes their image. • Most of the guests do enquire about the safety of the hotel before making a booking. Some of the guests mainly from the corporate sector do send their security specialists to assess the level of security at the hotel prior to making a booking. As the findings on this study were based on aims and objectives, recommendations for crime combating, proactive protection and future research were identified. The recommendations will, hopefully, also improve any inadequate security measures that may have been revealed by the study. / Criminology and Security Science / M.A. (Criminal Justice)

The key objective of this study was to determine the relationship between burnout (measured by the Maslach Burnout Inventory – Human Services Survey (MBI-HSS)), work engagement (measured by the Utrecht Work Engagement Scale), and sense of coherence (measured by the Orientation of Life Questionnaire developed by Antonovsky (1987)). A quantitative study using a cross-sectional survey research design was conducted on a randomly selected sample (N = 178) of nurses at a central hospital in Kwa-Zulu Natal. A theoretical relationship was established between the variables. The empirical relationship revealed statistically significant negative relationship between burnout and work engagement. A statistically significant negative relationship was also established between burnout and SOC. The findings add valuable knowledge to industrial and organisational psychology and can be applied to promote employee and organisational wellness. / Industrial and Organisational Psychology / M.

The commercial mining of asbestos occurred in four Provinces of South Africa (Northern Cape, North West, Limpopo and Mpumalanga). It was initiated in the late 1800's and lasted for over a hundred years into the beginning of this century. As a producer of amphibole asbestos, South Africa far outpaced every other country being responsible for 97% of global production. The last crocidolite mine closed in 1996 and chrysotile in 2002. Anecdotal information concerning environmental contamination as a result of the former mining activities and the improper disposal of mine waste tailings has been reported by a variety of authors. Few comprehensive or systematic surveys have been conducted to date to document this issue and very little quantifiable research has been completed on the communities located in close proximity to the former mine sites to determine the extent of contamination. In 2004-2006 communities were surveyed within the Northern Cape and North West Provinces to determine the extent and severity of environmental contamination. This research developed and applied a methodology to select those communities suspected of environmental contamination, a targeted survey methodology, and a protocol for rapid sample laboratory analysis. A total of 41 communities were initially predicted by the model to be suspected for environmental asbestos contamination. Based on the inclusion of local knowledge, a final 36 communities were selected for a screening-level field assessment, 34 of which were found to contain environmental asbestos contamination at rates ranging from 20 to 100% of the surveyed locations. A total of 1 843 samples of soil and building material were collected in the screening level assessment. One community (Ga-Mopedi) was selected as being representative of the total cohort and a more detailed house to house survey was completed. A total of 1 486 samples were collected during the detailed survey. Results of the detailed survey revealed 26.2% of the homes were contaminated with asbestos containing soil and/or building material. A theoretical quantitative cumulative exposure assessment was developed to estimate the disease burden within the study area population of 126,130 individuals within the surveyed communities resulting in a predicted range of 25-52.4 excess deaths per year from lung cancer and mesothelioma due solely to environmental exposures to asbestos pollution.

MPH / Department of Public of Health / The occupational health and safety of coal mine workers is one of the major occupational challenges in the mining industry. Coal mine workers face the looming perils of potential falls of volatile rocks, the ergonomic challenges caused by bending and lifting heavy objects in their daily work, the challenges caused by inhaling coal mine dust which can cause coal workers' pneumoconiosis (CWP) and a plethora of other hazards in both underground and open cast mines on a daily basis. The aim of the study is to assess the knowledge, attitude and practice of coal mineworkers pertaining to occupational health and safety at the Leeuwpan mine in Mpumalanga province of South Africa. The study adopted a quantitative, cross sectional descriptive design. Self-reported questionnaires with closed-ended questions were administered to the eligible participants. The study targeted the 3200 coal mineworkers who were employed at the Leeuwpan mine in Lephalale. A sample of 356 mineworkers was used as derived from Slovin’s formula and data was collected over a period of 5 days at the Leeuwpan mine. Measures to ensure validity and reliability were ensured and ethical considerations were observed. The Statistical Package for Social Sciences (SPSS) version 23.0 was used to analyse the data. Results and recommendations are based on the findings of the study. / NRF

Human related activities have influenced the rivers of the southern Western Cape since as early as the 1700’s. As there is no detailed information available on ecological status of the Holsloot River, a tributary of the Breede River, this study aimed to gain insight into the effect of impacts associated with human activities on the habitat integrity of this river. The study intended to understand how seasonal changes, catchment characteristics and events are reflected in the ecological status of habitats along the river by applying bio-monitoring and river health measurements at selected sites in the upper, middle and lower reaches of the Holsloot River and compare the results to that of an undisturbed reference site. Results obtained in this study are compared with data gathered in 2008/2009 to determine if the ecological status of the river had changed in the period between the two sampling times. The study included assessment of the ecological status of the river based on standard bio-monitoring protocol (SASS5, IHI, IHAS and VEGRAI) as well as in situ water quality analysis (pH, dissolved oxygen, electrical conductivity and total dissolved solids). The construction of the instream Stettynskloof Dam changed the configuration of the riparian zone and river channel in the upper catchment area. Agricultural- and other human related activities, with consequent water abstraction, non-point-source pollution, loss of riparian vegetation, as well as dense stands of alien invader plants influence flow patterns and affects river ecology, especially in the dry summer months. Providing sufficient stream flow and adequate water levels, human related activities can create a larger variety of habitat types available that can support larger biodiversity and higher productivity. The level of inundation and stream flow, influenced by water abstraction as well as irrigation return-flow from extensive drainage systems especially in the dry months, contribute to the loss of biodiversity in the middle and lower reaches of the river. Where the upper reaches of the river are largely natural with few modifications, the habitat integrity deteriorates in the middle reaches so much so that ecosystem functioning are collectively impaired in lower reaches due to human related impacts. Sensitive macro-invertebrates found at lower seriously impacted parts of the river however, were in all probability washed down from lower impacted upstream habitats and may expectedly be able to again occupy habitats downstream if water quality and habitat availability improves. / Environmental Sciences / M.

Wildfires destroy large tracts of veld and forest land every year in South Africa. These fires can be devastating, resulting in loss of human lives, the destruction of property and the loss of income, for example the forest fire in the Sabie district in Mpumalanga in 2007 which destroyed about 7% of South Africa’s forested areas. There are frequently legal disputes with respect to the origin of wildfires, the extent of the fire and the land cover destroyed by the fires. The forensic capabilities of remote sensing in detecting and analysing post-wildfire characteristics have become an important contribution towards solving such legal disputes and in understanding wildfire characteristics. These post fire products can be used as evidence in court cases. Most of the time those court cases came up a few years after the fire event. By then, little or no evidence can be found on the terrain where the fire was. Remote sensing archives provide a reliable source of data that can be used to analyse these events after these long intervals. The objective of this project is to highlight the methods used to generate these post-wildfire analysis products. / Environmental Sciences / M. Sc. (Environmental Science)

Text in English / The purpose of this research was to investigate occupational health and safety challenges and their impact on health care workers (HCWs) in selected public hospitals from the Gauteng Province, South Africa. Method: A quantitative descriptive cross-sectional survey was conducted among HCWs in the study sites. A two-staged sampling that include purposive sampling of study sites and census sampling of 2000 HCWs was used. Self-administered questionnaires were used to obtain data from HCWs. In addition, two different checklists were used to conduct retrospective records reviews to assess occupational health and safety (OHS) policy compliance and occupational injuries and diseases occurrence. The SAS Release 9.3 was used to analyse data. The Fischer Exact test and Chi-square were also used to determine the association of variables and P-value was set at <0.05 to indicate significant association. Results: A total of eight public hospitals and 926 (46.3%) HCWs who were all females nurses participated in this survey. Major occupational health hazards reported by the participants include: needle-stick injuries 275 (54.67%), slips trips and falls 67 (13.32%) and splashes 57 (11.33%). The analysis of open-ended responses indicated increased workloads, long hours of work and shift work as the most reported psychosocial hazards among HCWs. The reviewed records indicated that back injuries 22 (4.37%), tuberculosis (TB) 17 (3.38%) and asthmatic reactions 8 (1.59%) were the commonly reported occupational injuries and diseases among the HCWs. The records review also revealed a lack in the conducting of adequate medical surveillance among participants. The results showed poor compliance with the OHS policy and a negative impact of biological and psychosocial hazards on the HCWs. Conclusion: There was a high risk of exposures to biological hazards whilst providing care to patients, thus warranting the implementation of robust preventive measures. As a result, the guidelines were developed to promote the health and safety of HCWs with a view to promoting policy compliance and preventing the occurrence of occupational injuries and diseases as well as their impact among HCWs. / Health Studies / D.Litt et Phil.
