- Description: This dissertation investigated the life experiences of homeless persons and how they come to view their self-concepts as homeless men. The theoretical framework that underpinned this study was the self-concept theory and social identity theory. In this contextual descriptive study, four homeless men between ages of 28-50 participated in the study. Data was collected by means of disposable cameras and recorded interviews. Thematic analysis was employed to analyse data. The study found that when the participants first became homeless, they encountered stigmatisation and were not ready to accept the homeless identity as it conflicted with their past identity. However, with prolonged homelessness, they took on the new identity and the roles that come with it. The study found that homeless men view themselves as worthless due to their experiences on the street which include living under inhumane conditions, victimisation, and stigma associated with being homeless. The participants have internalised the negative utterances from housed people, which has negatively affected their self-image to a point where they view themselves as worthless,useless and forgetable. The study also found that homeless men use various methods to survive on the streets, which were both self-enhancing such as participating in the informal economy such as car guarding, car washing and collecting tins in exchange for money; and self-destructive such as using substances, risky sexual behaviour. The participants were found to have low self-concepts because of the tough experiences they encounter on the street.

- Description: At the centre of rural development are household livelihood strategies. The livelihoods of South Africa’s rural African poor have long been characterized by diverse activities, and intertwined with urban opportunities. This study describes the livelihood strategies of rural households, identifies the determinants of these livelihood strategies and seeks to identify the role of preferences and household characteristics in changing livelihood strategies in Shawbury in the small town in Qumbu. It also identifies the relationships between household and individual characteristics and livelihood strategies. A random sampling technique was used to select 100 households in Shawbury. Descriptive analysis techniques were used to describe the characteristics of the households and livelihood strategies and to identify the relationships between household characteristics and livelihood strategy preferences, a multinomial logit regression model was used. The livelihood strategies used for the multinomial logit regression were commercial agricultural production/ production for selling; subsistence agricultural production/ production for consumption; non-farm employment; social grants and remittances. For much of the research available for livelihood strategies, tools such as the sustainable livelihoods framework have been the focus for studying the determinants of livelihood strategies; however, these tools have little to no consideration for the aspirations and preferences of the individuals in question. This study highlights some possible tools that could be used to examine the influence of aspirations and preferences on changing livelihood strategies including the consumer choice framework, the domestic development cycle, the social network framework for decision-making, the social systems approach and conjoint analysis. For this study, the actual preferences of livelihood strategies among the households are presented using conjoint analysis. This study finds that households in the same area have different characteristics and that livelihood strategies of Shawbury’s households are primarily non- farm, that include dependency on remittances, social grants and formal employment. It finds that households that generate income from wage employment (non-farm) and farm activities are better off than other households. Analysis of the characteristics of rural households also revealed that age, labour endowment, education, and land size holding are some of the barriers that poor households in rural areas face when attempting to enter into high-return livelihood strategies. The multinomial logit regression model has helped to identify some of the factors that influence the preference of certain livelihood strategies by households, are gender of the household head, age of the household head, size of the land owned, and educational level of the household head, household size, and livestock value. This analysis presents evidence about the relationship between household characteristics contributing to the adoption of certain livelihood strategies by people of Shawbury. The conjoint analysis has helped to identify that the most preferred to the least preferred livelihood activities are non-farm labour activities, crop production, animal production, contact with family/leisure and other natural resource based activities respectively.

- Description: Urban green spaces and trees provide multiple benefits to urban residents and the sustainability of cities. A poorly examined benefit is the provision of fodder to urban livestock. However, the presence and activities of livestock may be incompatible with other uses, although this has been little studied. We examined the impacts of livestock on trees and parks along a gradient of declining livestock density, complemented with a tree planting experiment to monitor damage. Neighbouring residents and park managers were interviewed regarding their perceptions of damage caused by livestock. The negative impacts on soil compaction, tree damage and death increased with increasing livestock densities. Thorny tree species were damaged significantly less (13 %) than non-thorny species (77 %), as were protected trees (25 %) relative to unprotected ones (65 %). There was more tree damage in public green spaces (PUGS) (54 %) than control sites (38 %). The majority of local residents felt that livestock should not be allowed in formal PUGS, and most urban park managers regarded livestock damage as a strong disincentive to plant trees. These results show the need for management of the trade-offs caused by livestock and greater appreciation of livestock as agents shaping aspects of PUGS.

- Description: The main objective of the study was to determine how phase feeding manipulation affects growth performance, feed cost, carcass characteristics and quality of meat from broiler chickens. A total of 180 day old un-sexed broiler chicks (Cobb 500) were separated into 3 dietary treatments of 60 birds per treatment and each treatment was replicated 3 times with 20 birds per replicate. The dietary treatments were as follows: T1 (starter 1-7 days; grower 8-21 days; finisher 22-35 days), T2 (starter 1-14 days; grower 15-21 days, finisher 22-35 days) and T3 (starter 1-14 days; grower 15-28 days; finisher 29-35 days). Feed intake and body weight gains were recorded weekly in kilograms. Average daily gain and feed conversion ratio were computed weekly. At day 35, the chickens were slaughtered and 12 representative breast muscles from each treatment were used for the determination of muscle pH (pH1, pH24 and pH48) and colour coordinates (Lightness – L*, redness – a* and yellowness – b*) in triplicate at 1 hour, 24 hours and 48 hours post-mortem.Feed intake (FI), feed conversion ratio (FCR), average daily gain (ADG) and average body weight at slaughter (ABW) were not significant (P>0.05) amongst the treatments. The most cost efficient feed (which accumulated the cheapest cost feed per kg were) T1 (R11.32) and T3 (R11.32) although there was a slight difference in the gross profit of these treatments T1 (R45.71) and T3 (R44.48). Carcass characteristics were the same (P > 0.05) across the treatments except for the wing, thigh, drumstick and the breast (P < 0.05). T2 had the highest wing weight (166.63±8.60), T1 (113.03±8.60) and the lowest in T3 (74.46±8.60). The thigh weight were greater (P<0.05) in T2 (185.69±4.34); T1 (185.54±4.34) compared to T3 (166.97±4.34) which was lower. Treatments 1 (204.17±6.57), T2 (197±6.57) had heavier (P<0.05) breast weights than T3 (186.06±6.57). Dietary treatments had no significant effect (P > 0.05) on pH of the breast meat. No differences were observed in colour during the 1 hour period after slaughter. At 24 hours after slaughter, the L* values were different (P < 0.05) in T1 and T2 (44.3 ± 0.37; 43.7 ± 0.37), respectively, T1 and T3 were the same. The a*-values were different (P < 0.05) at 48 hours after slaughter for T1 and T3 (4.5 ± 0.27; 3.4 ± 0.27), T2 was the same as T1. It was therefore, concluded that since manipulation of starter phase did not have adverse effects on growth performance, gross profit, slight statistical difference in meat quality attributes and carcass characteristics. Therefore, the manipulation of starter diet has the potential to be used in broiler production.

- Description: This dissertation discusses the application of additive manufacturing technologies for production of a large-scale rapid prototyping machine, which will be used to produce moulds for prototype composite turbine blades for the emerging renewables energy industry within the Eastern Cape region in South Africa. The conceptualization and design of three complete printer builds resulted in the amalgamation of a final system, following stringent theoretical design, simulation, and feasibility analysis. Following the initial product design cycle stage, construction and performance testing of a large-scale additive manufacturing platform were performed. In-depth statistical analysis of the mechatronic system was undertaken, particularly related to print-head locational accuracy, repeatability, and effects of parameter variation on printer performance. The machine was analysed to assess feasibility for use in the mould-making industry with accuracy and repeatability metrics of 0.121 mm and 0.156 mm rivalling those produced by some of the more accurate fused deposition modellers commercially available. The research data gathered serves to confirm that rapid prototyping is a good alternative manufacturing method for wind turbine blade plug and mould production.

- Description: My novella is about a mine worker and his family. Set in both Lesotho and South Africa, it engages the effects of migrant labour on families in post-apartheid South Africa. Told through the eyes of the different family members, the narrative uses shifting points of view and moves fluidly through time to present an intimate but complex view of the lives of ordinary working class people. It incorporates witchcraft and ghosts to reveal the blurred lines between the realms of life and death. This collection is inspired by my own father who is a former mine worker. I am influenced by Joyce Carol Oates and Chibundu Onuzo's darkly realistic style, Veronique Tadjo’s explorations of migration and death, the family chronicles of Chimamanda Ngozi Adichie and Yvonne Adhiambo Owuor. I am also inspired by female fantasy and horror writers such as those collected in Ann and Jeff VanderMeer’s anthology, Sisters of the Revolution: A Feminist Speculative Fiction Anthology.

- Description: Written in non-linear fragments, my thesis is what Audre Lorde in her novel Zami calls a "biomythography" - the weaving together of myth, history and biography in epic narrative form, a style of composition that represents all the ways in which we perceive the world. Using repetition and shifting memories, I draw from my bicultural upbringing in Offenbach, a city in Germany populated mostly by migrants, as well as my experience of working in art and culture internationally, travelling and living in different countries. Interrogating objects, buildings, family photographs, books and movies, and listening to the silences of the unvoiced, I upset and play with experiences of othering, assumptions and expectations about identity and ask questions about home, belonging and migration, mother tongue and translation. I draw inspiration from Korean American artist Theresa Hak Kyung Cha's use of texts, documents and images to explore dislocation and memory, as well as authors who engage language, translation and belonging such as Mikhail Shishkin, Yoko Tawada, Gloria Anzaldua and Mohammed Khair-Eddine.

- Description: Written in non-linear fragments, my thesis is what Audre Lorde in her novel Zami calls a "biomythography" - the weaving together of myth, history and biography in epic narrative form, a style of composition that represents all the ways in which we perceive the world. Using repetition and shifting memories, I draw from my bicultural upbringing in Offenbach, a city in Germany populated mostly by migrants, as well as my experience of working in art and culture internationally, travelling and living in different countries. Interrogating objects, buildings, family photographs, books and movies, and listening to the silences of the unvoiced, I upset and play with experiences of othering, assumptions and expectations about identity and ask questions about home, belonging and migration, mother tongue and translation. I draw inspiration from Korean American artist Theresa Hak Kyung Cha's use of texts, documents and images to explore dislocation and memory, as well as authors who engage language, translation and belonging such as Mikhail Shishkin, Yoko Tawada, Gloria Anzaldua and Mohammed Khair-Eddine.

- Description: Information and Communication Technology (ICT) has evolved into a pervasive commodity in modern enterprises. ICT enables enterprises, regardless of sector, to achieve their strategic objectives. Similarly, ICT is regarded as a critical enabler in South African municipalities to reach their objectives and ultimately deliver sustainable services to their communities. This dependence on ICT, therefore, necessitates a resilient ICT environment where minimal disruption to ICT is a primary goal. Unfortunately, as reported by the Auditor-General of South Africa, the majority of South African municipalities are neglecting to address the continuity of their ICT services. Failing to implement adequate ICT continuity controls restrict these municipalities from achieving their strategic goals and, as a result, fulfilling their constitutional mandate of service delivery. It is, therefore, the objective of this study to devise a method, consisting of a theoretical foundation and a supporting tool-set, to assist municipalities in addressing a real-world ICT continuity problem. This method aims to be scalable and usable within different municipalities, and be simplistic and comprehensible enough to implement. The theoretical foundation will introduce the concept of ICT Readiness for Business Continuity, based on the recommendations of international best practices and standards, for example, the ISO 27031 (2011) standard. Furthermore, by considering various challenges within local government, the tool-set will ultimately help municipalities to help themselves in this regard.

- Description: Many of the larger estuaries along the South African coastline are highly degraded due to human impacts, highlighting the need to conserve pristine systems. There are approximately 100 micro-estuaries along our coastline which have not yet been identified or classified and hence their ecological functioning is unknown. The aim of this study was to identify and classify micro-estuaries along the Eastern Cape coast. Specific objectives of the study were to: 1) map the distribution of estuarine habitats in a selection of micro-estuaries and assess changes over time; 2) measure the physico-chemical characteristics of the micro-estuaries in the field; 3) investigate the distribution of vegetation, identify macrophyte species and habitat integrity and classify the micro-estuaries sampled using abiotic and botanical characteristics. A total of 30 systems were identified of which 10 were selected for sampling which took place seasonally (2015-2016). A relationship between open water surface area and short term rainfall was only evident in Cunge, Sandy Bottom and Ichabana. In the field it was observed that after heavy rainfall, open water surface area increased and mouth breaching occurred. Salinity was the only water column characteristic that showed differences; salinity increased in response to over wash events. Sand was dominant in all systems and there were no differences in sediment characteristics. A total of 8 macroalgal species, 16 estuarine macrophyte species, six freshwater species and 72 riparian plant species were found. Seed bank reserves were low in all systems despite them being vegetated. Only abiotic characteristics were used for classification using Principle Components Analysis since there were no botanical differences between systems. Micro-estuaries were larger (> 0.03 ha), had a higher salinity (oligohaline, mesohaline and polyhaline conditions) and a constant water body. Micro-outlets were smaller (< 0.03 ha), had a lower salinity (oligohaline conditions were most common) and showed periods of drying. Five micro-estuaries (Shelbertsstroom, Kwesani, Cunge, Mtwendwe and Mtendwe) and five micro-outlets (Stromatolite, Sandy Bottom, Ichabana, Palm Tree and Black Rock) were classified. This study has shown that the micro-estuaries along the Eastern Cape coast are pristine (i.e. intact riparian zone and catchment), untouched and highly dynamic systems (i.e. great variation in water surface area and mouth condition) highlighting their need for protection.

- Description: Environmental growth conditions and mechanisms involved in sediment transport by needle ice have historically been difficult to assess and are poorly documented. The spatial and temporal dynamics that relate to the environment, growth and decay of needle ice are not fully understood. This study monitored needle ice growth, melt and visually identified sediment displacement mechanisms by needle ice, with the aim of revealing environmental growth criteria, timing of growth/melt, ground-surface-air energy balance and sediment displacement mechanisms. Furthermore, the impact of needle ice displacement on vegetation and patterned ground formation was analysed. High-frequency visual monitoring, using three cameras, supplemented by high-frequency measurements of air temperature, soil moisture and wind speed was used to investigate needle ice growth and decay dynamics. Results from visual and environmental monitoring of needle ice growth, showed that the needle ice growing environment was more dynamic, especially in terms of surface temperature, than previously argued. Needle ice growth was observed to occur during surface temperatures from -2.0°C to 2.2°C, soil moisture levels from 0.4% to 37.4% and in winds speeds of 0 m/s to 12.6 m/s. Needle ice initiation was documented a few minutes to hours before or after the onset of surface temperature dropping to below 0°C. Imagery displayed that the depth of ice nucleation was variable within the soil column, possibly relating to the energy balance of radiative cooling, convective heat loss, ground conductivity and latent heat release at the air-surface-ground boundary. Heaving and resettling, toppling and rolling were identified as slope displacement mechanisms when needle ice decayed. Animal trampling and hail were additionally documented as substantial surface altering processes. Furthermore, no impact of needle ice reducing vegetation stability was identified, although a tendency to hinder vegetation expansion was noted. Also, no creation of patterned ground was observed as a result of needle ice decay.

- Description: In today’s dynamic market, it is crucial that logistics systems understand their activities and processes in an efficient way. Lean, in essence, is a method to assist companies in rendering efficient services to customers (Andrejic, 2013, p. 84). The Lean approach for waste elimination can be applied to many different types of operations whether in manufacturing or service industries. The identification of warehousing wastes is sometimes considered difficult in its identification within processes (Villareal, Garza, Rosas & Garcia, 2012, p. 278). The purpose of this case study is to contribute to finding a solution for the decreasing operational efficiency in the operation under study. The researcher found that this paper filled an important research gap in terms of offering management of the selected logistics institution a better understanding of the different waste types in each process. Operational areas such as receiving, unboxing, put-away, picking and issuing were examined as possible reasons for concern about service orientated wastes. The research was conducted through observations and thereafter a questionnaire was distributed amongst a sample of 40 employees within a specific logistics institution. The study discussed certain key factors in Lean, specifically focusing on the types of waste in a service environment.

- Description: The main aim of the analysis is to investigate the intermestic factors that led to political decay in Zimbabwe. By thoroughly assessing the dynamics of political development, one is then able to identify the factors that drive a state towards political decay. The study commences by delineating the domestic factors that contributed to the crisis in Zimbabwe. One unravels how the absence of democracy leads states to political decay. Democracy structured on effective institutions, good governance, transparency and a good relationship between civil society and the state are identified as being key factors that contribute towards political development. By assessing these factors meticulously, one is able to identify how disregarding them leads to political decay as evident in the case study. The study also explores how failed government policies can lead to political decay. Thus, ESAPs, the chaotic land reform program and corruption are discussed as being key contributing factors of political decay in Zimbabwe. The study makes use of interviews with 15 participants. The main objective of interviews in this study is to be able to compare the lived experiences of Zimbabweans vis a vis the information gathered from secondary sources. Also, by using thematic analysis on the gathered data, one will be able to unravel the participants’ perceptions regarding factors that led to stunted political development in the country. Contrastingly, the study seeks to explore whether domestic factors alone can be blamed for the crisis. One begins to question if external factors were also responsible for the crisis in the country. A closer look at the topic of discussion reveals that the AU, SADC and the EU also contributed to the crisis in Zimbabwe. Through the use of discourse analysis, one explores the reactions of the SADC and AU and how quiet diplomacy and the lack of a sterner response towards Mugabe led to an exacerbation of the crisis. Leaders who blatantly disregard the principles of democracy ought to be punished accordingly and not appeased, as in this case study. The EU sanctions on the country are also critically analysed and identified as being key contributors to the crisis. One ponders on whether they can be identified as a selfish response to protect EU interests in the country and punish Mugabe. By the end of the analysis it should be clear that both internal and external factors contributed to the political decay in Zimbabwe, as no country can live in complete isolation from other states in this global era.

- Description: The aim of this study was to assess whether ambient-air pollution contributed negatively to ambient-air quality, and subsequently to human health in the Nelson Mandela Bay Municipality (the study area). A research design that is descriptive and explorative in nature was followed. The research methodology conformed to the following procedure. Firstly, an emission inventory of one hundred and fifty (150) emission sources listed on the data base of the Nelson Mandela Bay Municipality was compiled (“N” and “n” = 150) in a quantitative research approach. Emission data from these sources, together with the relevant meteorological data from the weather stations in the study area (“N” and “n” = 5) were collected and used as input into a geographical information system-software program to quantify the contribution of each emission source to ambient air pollution. The said software program was also used to simulate the dispersion of emissions over the study area. The emission inventory was compiled in consultation with a focus group of experts in the field of air-pollution control in a qualitative-research approach. Secondly, health records of the patients who attend the clinics in the said municipality (“N” and “n” = 49) were assessed for air pollution-related health outcomes. Nineteen (19) of the forty-nine (49) clinics were situated in Sub-District A; fifteen (15) clinics were situated in Sub-District B. The last fifteen of the clinics were situated in Sub-District C, which was also the least-industrialised sub-district. Sub-districts A and B were found to be the most industrialised of the three Sub-districts. Air pollution related health statistics were compiled for the following air-pollution-related health outcomes, namely: lower respiratory tract infections in children under five (5) years of age, as well as pneumonia and asthma in the general population.

The largemouth bass Micropterus salmoides (Centrarchidae; Fig.1) was introduced in 1928 in South Africa for recreational anglers. Concerns about its impact on local indigenous freshwater and estuarine fish populations are raised (Gratwicke and Marshall, 2001; Weyl and Lewis, 2006; Wasserman et al., 2011). In particular, the predatory impact of M. salmoides on estuary-associated juveniles of marine fish species must be elucidated.

- Description: A wide range of theoretical and empirical studies have been carried out on various determinants of private investments in different economies. This dissertation specifically focuses on the impact business confidence on private investments with regards to the South African economy for the period between 1990 and 2014. The private investment sector in South Africa has, to a greater extent contributed to the overall GDP of the economy. Even though business confidence has a considerable impact on private investments, this study also took into consideration other variables that affect the private investment sector such as interest rates, exchange range and GDP To determine short-run and long-run relationships of business confidence on private Investments in South Africa, a vector error correction model was employed. In order to avoid spurious regression, the ADF test and the PP test were used to test for stationarity. Results of the study indicate that private investments are subject to permanent changes because of changes in business confidence. In addition to that, not all variables have a long-term relationship with private investments but business confidence has a significant long run relationship with private investment. After conducting an econometric analysis, results revealed that Business Confidence and Gross Domestic Product have a positive impact on private investments. On the other hand, interest rates and exchange rates have a negative impact on private investments in South Africa. Various policy recommendations were established on both Private Investments and Business Confidence.

On the other hand, interest rates and exchange rates have a negative impact on private investments in South Africa. Various policy recommendations were established on both Private Investments and Business Confidence.

- Description: Solanum nigrum L. is a wild vegetable that is highly recognised for its high nutiritional and therapeutical purposes. However, proper identification of the plant is essential not only to plant scientists but to a wide range of users. Therefore, the plant’s roots, stems and leaves cultivated on different soil types were viewed under the Scanning Electron Microscope while the leaves were further viewed under the Light Microscope. significant increase was observed in densities of stomata, guard and subsidiary cells of leaves of S. nigrum grown on silty clay loam soil. The SEM analysis revealed abundant glandular and non-glandular trichromes on both surfaces of the leaves. The glandular trichome is known to be responsible for the storage of bioactive compounds for which this plant is well known. Cultivation was embarked upon, for the availability of the plant at all times. However, propagation was by seed alone, therefore, quality seed is necessary for cultivation. Study was carried out on seeds extracted from plants growing in the wild in Alice for the seed viability, germination and seedling emergence when subjected to different soil texture types and sowing depths. The seeds were 98.3 percent viable. Highest germination (94.66 percent) was recorded in sand paper scarification, 15, 20 and 25ºC. Continuous darkness and temperatures lower than 5ºC and higher than 35ºCwere detrimental to the seeds. Silty clay loam soil and a depth of 2 cm had the highest seedling emergence 90 percent and recommended as the ideal condition for seedlings emergence. The growth, yield and physiological response of S. nigrum to sandy clay loam, silty clay loam, clay loam, loam soils and control soil (sandy loam) were investigated in the glasshouse in two separate trials. The ANOVA analysed data results indicated that plant samples on silty clay loam significantly increased in height, stem girth, plant root, leaf area, number of leaves, number of branches, number of flowers, number of fruit bunch per plant dry weight, as well as weight of fruit bunch. However, plant samples grown on clay loam and loam soils recorded increased chlorophyll and produced dark green leaves. It is conceivable that silty clay loam soils have a strong ability to support the physiological growth and the yield of S. nigrum. These soils are therefore recommended for the cultivation of this plant. S. nigrum cultivated on these soils was evaluated for proximate compositions, anti-nutrients, vitamins A, C and E and mineral compositions using standard analytical methods. Using the translocation factor, the minerals’ toxicity accumulation levels in the plant were also determined. Accumulation of proximate parameters in the first and second trials are: ash (11.25-12.25 percent and 11.14- 11.54 percent), crude fibre (19.24-19.95 percent and 18.71-19.35 percent), protein (36.72-38.98 percent and 34.47-37.00 percent), phytate (0.84-1.17 and 0.88-1.15 mg/ml), saponnin (94.10-97.00 and 94.17-97.00 percent) and alkaloids (43.03-45.76 and 42.08- 44.10 percent) respectively. Vitamin A ranged between 117 and 137 mg/kg and betweens 108 and 128 mg/kg, vitamin C between 100 and 118 mg/kg and between 96 and 108 mg/kg and vitamin E between 250 and 269 mg/kg and between 227 and 261 mg/kg in the first and second trials respectively. The quantities of macro and micro-nutrients recorded in S. nigrum showed that this plant is a reservoir of nutrients. Plants cultivated on clay loam, silty clay loam and loam soils accumulated elevated nutritients compositions. Investigation was made on the ability of S. nigrum cultivated on different soil texture types to synthesise phytochemicals such as phenol, flavonoid, alkaloid proanthocyanidins, tannins, saponins and antioxidant. Highest concentrations of phenolics (73.87 mg/g), flavonoids (58.41 mg/g), proanthocyanidins (875.74 mg/g), tannins (49.32 mg/g), saponins (875.74 mg/g) and alkaloid (47.50 mg/g) contents were recorded in plant sample cultivated on silty clay loam soil. Also, highest radical scavenging power using DPPH (0.0102 mg/g), ABTS (0.1062 mg/g) and FRAP (0.8395 mg/g) were recorded in plant samples grown on silty clay loam and the next high values were recorded in plant samples grown on clay loam soil. It is showed in this study that silty clay loam soil and clay loam soils are the best soil types for cultivation of S. nigrum for increased antioxidant properties/ oxygen radical scavenging activities. Investigation was made on chemical compositions and antioxidant properties of essential oil extracts of S. nigrum shoot and root cultivated on different soil textures. The Gas Chromatography-Mass Spectrometry (GC-MS) profiling revealed variations in the quality index (QI) and number of chemical constituents of the oil of S. nigrum cultivated on different soil texture types. Geraniol and citronellol were two principal components of high quality common to oil from shoots and roots fromplants cultivated on all soil types. Results of DPPH and ABTS assays of the shoot oil showed that S. nigrum cultivated on clay loam soil had the highest antioxidant power. The presence of citronellol and geraniol among the major compounds is an indicaton of the plant’s role in defensive mechanisms. The work indicated that soil texture has effect on the quality, quantity and chemical compounds synthesised in the shoots and roots of S. nigrum. Antibacterial activities and the efficacy of S. nigrum cultivated on different soil types were carried out on reference strains of 4 gram-positive and 4 gram-negative bacteria. Toxicity evaluation of the plant’s acetone extract and water extract were also assessed on lethality of brine shrimp eggs. Plant water and acetone extracts exhibited strong antibacterial activity against Pseudomona aeruginosa, acetone extracts against Bacillus cereus, Listeria and Escherichia coli. Significantly (p< 0.05) low concentration (0.25 mg/mL) of acetone extracts from plant shoot cultivated on silty clay loam and clay loam soils inhibited B. cereus and P. aeruginosa. Antimicrobial activities of extracts of plant cultivated on clay loam appeared to be more superior to extracs from plants grown on other soil types. Toxicity of the plant extracts (water and acetone) was concentration and time dependent. The LD50 values for all plant extracts were greater than 1000 mg/mL which showed they are non-toxic.

- Description: In this study, I investigated the interaction between two megaherbivores, the African elephant and white rhinoceros, that has the potential to impact grazing lawns of which white rhino are the creators and maintainers and elephants are potentially the modifiers. I hypothesized that as elephants browse, they discard a variety of coarse woody debris onto the ground; should this woody debris (of varying amounts and sizes) fall onto grazing lawns, white rhino either move them, consume grass around the woody debris or abandon the lawn entirely. If high levels of woody debris are deposited here, grazing by white rhino is likely to be prevented, at which time I predicted that mesoherbivores would have a competitive advantage in accessing forage that white rhino cannot. I examined the mechanistic links between different levels of elephant-deposited woody debris and grass response at a point scale and feeding patch spatial scale of grazing lawns in an African savanna. In addition, I assessed the response of mesoherbivores in terms of vigilance behaviour with increasing levels of predation risk posed by increasing levels of woody debris. I present the first evidence of an indirect effect of elephant on white rhino foraging behaviour. I demonstrate how increasing levels of woody debris lead to a decreasing probability of foraging by white rhino. I also demonstrate how the probability of foraging by mesoherbivores increases as the amount of forage increases. However, since this study took place during a severe drought where resources are extremely limited, I was unable to properly separate the effects of elephant-deposited woody debris from the severe lack of rainfall on grass response and subsequently herbivore foraging behaviour. Due possibly to the drought, mesoherbivores responded less or not at all to risk factors such as woody debris therefore woody debris was not a predictor of vigilance behaviour in my study. This study contributes to our understanding of how the impacts of elephants, as ecosystem engineers, have cascading effects on savanna ecosystems. My study showed that elephant impact mediates the foraging behaviour of white rhino during a drought. However, under average rainfall periods, my original hypothesized effect of the indirect impacts of elephants on white rhino foraging and grazing lawn dynamics could still hold. This key hypothesis that I was unable to test under ‘normal’ conditions due to the drought is still valid and functionally important for understanding the ecosystem processes driving grazing lawn formation, persistence and composition in African savannas where elephants and white rhinos coexist.

- Description: The White paper on Transforming Public Service Delivery no 1459 of 1997 stipulates that the wellbeing of employees needs to be accounted for. A directive to have employee health and wellness programmes established in all government departments was given by the director-general of the Department Public Service Administration in 2008. The Employee health and wellness programme is aimed at promoting and improving employee wellbeing, which is also linked to organizational wellness. The primary aim of the Employee Assistance Programme (EAP) is to make a positive contribution towards maximum employee productivity and effectiveness in the workplace. Employee health assessment conducted by the Department of Social Development in 2006 and 2009 confirmed that South African organizations, including the Department of Social Development, experience high levels of employee poor health. Studies suggest that both employees and the employers need to pay attention to the improvement of employee health and wellness. In 2012, an integrated employee health and wellness policy was developed to improve the Department of Social Development employee wellness. The interest to conduct the study emanates from the researcher‟s own supposition that the policy has not been fully implemented, this deduction is based on the fact that, although the policy has four critical focus areas, some of these areas, such as counselling, are not rendered. Literature reviewed includes the process of policy implementation and description of employee health and wellness, benefits of employee health and wellness programme for both employees and employer. A mixed method study was conducted to explore the implementation of the employee health and wellness policy as a strategy to improve both employee and organizational wellness within the Department of Social Development, Eastern Cape - Amathole District. The population of the study included both DSD management and non-managerial employees from Amathole District; the study also includes the Eastern Cape Department of Transport, Amathole District Municipality and South African Police Service (Mdantsane). Themes that were identified from qualitative data through semi- structured interviews by means of audio-recorder were triangulated through questionnaires and document analysis. Since the policy came into effect in 2012, results show that the implementation has been confronted with a number of challenges which include lack of support from the top management. Lack of buy in by DSD management has serious implications on the policy objectives; these include the inadequate distribution of capital, human and physical resources necessary to implement the policy. In order for the DSD to improve the implementation of employee health and wellness policy, the management needs to ensure that there is adequate provision of human and capital resources. Employees should be well-informed on policy guidelines and procedures and benefits to stimulate maximum utilisation. A decentralisation of implementation to Area offices is necessary to promote accessibility of services and prevent unnecessary delays in service delivery.
