- Description: An investigation of the anatomy and gas exchange characteristics of Mariscus congestus in three different habitats was undertaken in order to establish whether M. congestus from the three different habitats displayed any ecotypic responses when placed in a new similar environment. It was hoped that the results of this investigation would yield evidence that would support the ecotype concept similar to the investigations of Milner and Hiesey (1964), Green (1969) and Slayter and Ferrar (1977). On the basis of the site leaf anatomy, M. congestus investigated at the coast (site 1) differed in many respects from the inland plants (sites 2 and 3). These differences suggest that the coastal plants may have undergone a slight ecotypic divergence from the inland plants. The anatomical investigation also suggested that the leaves of M. congestus from all three sites may either be C₄ NADP-ME or PCK and that all had typical Chlorocyperiod anatomy. The habitat microclimates at sites 1-3 had different light and water regimes. There were no significant differences between the 12 month temperature environments of the three sites. There was however, a minor difference between the coastal (high temperature) and the inland (lower temperature) sites. M. congestus at the three sites had significantly different CO₂ assimilation rates, transpiration and stomatal conductance in response to the differing habitat microclimates. The water use efficiency of the sites were however, similar. Site 1 attained the highest CO₂ assimilation rates, transpiration, stomatal conductance, and water use efficiency and site 3 the lowest. Under similar conditions the gas exchange data for the potted plants indicated that M. congestus from the different sites was typically C₄. The optimal photosynthetic temperatures of all the sites was above 30°C and they did not show significant inhibition of CO₂ assimilation by different oxygen concentrations. The results of the laboratory investigation of the potted plants suggested that the only site-specific (ecotypic) response of M. eongestus was the light intensity at which the plants from the different sites were light saturated. The light and temperature response of field plants under field conditions was not comparable to the light and temperature response of potted plants under laboratory conditions. This may have been due to the field results being obtained under differing water and soil nutrient regimes. The potted plants may also have had a reduced root mass compared to their field counterparts and the potted plants may have also have become root bound. Under field conditions the plants had differing light saturation points and optimal photosynthetic temperatures compared to the potted plants. This investigation thus did not support the hypothesis stated in this thesis. The data in this investigation thus may indicate that plants with as diverse habitats as Mariscus congestus that are removed from their natural habitats display rapid changes in gas exchange characteristics in response to their new microclimates, with few ecotypic physiological characteristics of the old habitat being retained.

- Description: Analysing the root causes of the challenges experienced by local municipalities in service delivery. A single case study research approach was utilised and the study was qualitative in nature. The research focussed on the challenges of rural local municipalities rendering municipal services to their communities and the root causes of these challenges. It furthermore assess whether the Local Government Turnaround Strategy can make a positive impact on service delivery, specifically within rural municipalities such as the Ngqushwa Local Municipality. The case study made use of an in depth literature review based on secondary sources as well as a semi structured interview with the Municipal Manager of the Ngqushwa Local Municipality. In the event that the root causes hampering service delivery can be solved, specifically in rural municipal areas, it will not only assist municipalities to comply with their constitutional duties, but will also assist with various socio-economic problems which exist within communities specifically in rural areas. The researcher experienced reluctance by the relevant employees of municipalities to part take in the research effort and to make themselves available for interviews. Large backlogs exist in relation to service delivery of municipalities specifically in rural areas. The research effort provided relevant information in relation to the root causes of the challenges which are experienced by local municipalities and what problems must be solved in order for municipalities to effectively and efficiently render service to communities in a sustainable manner.

- Description: A series of rhenium(I) complexes with monodentate benzazole ligands containing the fac-[Re(CO)3]+ was synthesized. The rhenium(I) compound [ReCl(Hmbt)2(CO)3] was prepared from the reaction of [Re(CO)5Cl] and 2-aminobenzothiazole (Hmbt) in toluene. The ligand coordinates in a monodentate manner via the thiazole nitrogen atom. A similar reaction between [Re(CO)5Cl] and N-(1,3-benzothiazol-2-yl)-2- chloroacetamide (Hbct) resulted in the formation of [ReCl(Hbct)(CO)3(NCMe)], where only one ligand binds per rhenium in a monodentate fashion. The reaction of ligands 2-mercaptobenzimidazole (Hmbi) (dibenzothiazol-2-yl)tetraazathiapentalene (Hdbt) with rhenium(I) gave [ReCl(Hmbi)2(CO)3] and [ReCl(Hdbt)2(CO)3] respectively. The study on the coordination behaviour between ethyl-(1H-benzimidazol-2-yl-sulfanyl) acetate (Hbsa) and [Re(CO)5Cl] surprisingly gave the dimeric species (μ-Cl)2[Re(Hbsa)(CO)3]2, where the two rhenium atoms are bridged by two chloro ligands. The coordination of Hbsa occurs through the imidazole nitrogen, leaving the ethoxy tail free on each Hbsa ligand. The coordination behaviour of benzimidazole and benzothiazole derivatives gave rhenium complexes in oxidation states I, III and V, where all the ligands coordinate as bidentate N,N-chelating ligands. The study on 2-(2-aminophenyl)-1-benzothiazole (Hapt) and 2-(2-aminophenyl)-1-benzimidazole (H2apz) with [ReVOCl3(PPh3)2] resulted in the formation of [ReVOCl2(apt)(OPPh3)] and [ReVCl2(apz)(PPh3)2](ReO4), respectively. 1,2-Bis(2-benzimidazole)-1,2-ethanediol (Hbed) and 2,6-bis(2- benzimidazol-2-yl)pyridine (H2bip) were studied towards rhenium(I) and rheniumV) respectively. The former gave a dimeric species (μ-bbi)[Re(CO)4]2 (H2bbi – bisbenzimidazole) by reaction with [Re(CO)5Cl], whereas H2bip produced the rhenium(III) cationic salt [ReCl3(H3bip)(PPh3)]Cl, where the ligand coordinates as a cationic H3bip+ with protonation of an uncoordinated imidazole nitrogen atom. The pyridine derivatives 2-hydrazino-pyridinyl-2-benzothiazole (Hhpt) and (E)-1-benzo[d]thiazol-2-yl)-2- (pyridin-2-ylmethylene)hydrazine (btp) were reacted with [Re(CO)5Cl]. The neutral complex [ReCl(Hhpt)(CO)3] was isolated upon reaction with Hhpt, where Hhpt coordinates as a neutral bidentate ligand. The reaction of [Re(CO)5Cl] with btp gave two different complexes when using different solvents. In methanol, [ReCl(btp)(CO)3] was isolated, whereas in toluene, the conjugate of btp (btp1) was formed which resulted in the formation of [ReCl(btp1)(CO)3]. The study on potentially bidentate thiourea derivatives containing a benzothiazole moiety towards [ReI(CO)3]+ and [ReVO]3+ cores gave rise to a wide variety of complexes. The reaction of [Re(CO)5Cl] with N-phenyl-N-(2-benzothiazole)thiourea (Hpbt) produced the rhenium(I) complex [Re(Hpbt)(pbt)(CO)3]. Hpbt coordinates both as a monodentate neutral ligand and as a bidentate monoanionic chelate. The study of the reaction between trans-[ReOCl3(PPh3)2] and Hpbt gave the rhenium(V) product [ReOCl2(pbt)(PPh3)], with pbt acting as a bidentate ligand. The reaction of 1-(1,3- benzothiazol-2-yl)-3-benzoylthiourea (Hbbt) with [Re(CO)5Cl] led to the isolation of [ReCl(Hbbt)(CO)3]. Similar reaction of Hbbt with trans-[ReOCl3(PPh3)2] gave the unique compound [ReOCl2(Hbnt)(PPh3)], where the ligand coordinates via the ketonic oxygen and a methine carbon. The complex [Re(Hmby)(mby)(CO)3] was isolated upon reacting [Re(CO)5Cl] with methylbenzothiazol-2-ylidenecarbamodithioate (Hmby), with Hmby coordinating as a monodentate neutral ligand and mby as a bidentate monoanionic chelate. The coordination behaviour of N-(benzothiazol-2-yl)-S,S’- dimethyldithiocarboimine (Hbdc) towards rhenium(I) led to the formation of [ReCl(Hbdc)(CO)3]. The reactivity of 1-(benzothiozol-2-yl)-3,3-dimethylthiourea (Hbdm), a derivative of Hmby, was studied with trans-[ReOCl3(PPh3)2] and trans- [ReO(OEt)I2(PPh3)2] producing the square pyramidal compound [ReOCl(bdm)2] and the salt [Re(bdm)2(MeCN)2]I3, respectively. Pyrazole derivatives containing a benzothiazole ring were studied towards rhenium in oxidation states +I and +V. The reaction between 2-(3,5-dimethylpyrazol-1-yl)benzothiazole (Hdmp) and [Re(CO)5Cl] gave the neutral rhenium complex [ReCl(Hdmp)(CO)3], whereas its reaction with [ReOCl3(PPh3)2] surprisingly results in the formation of a dimeric complex (μ-O)[ReOCl2(Hdmp)]2. The study on the reactivity of 1-(benzo[d]thiazol-2-yl)-4-methyl-1H-pyrrol-2-ol (Hbtm) with [Re(CO)5Cl] gave the unexpected trimer [Re(btm)(CO)3]3 containing the fac-[Re(CO)3]+ core. The ligand btm forms a bridge between each rhenium metal, serving as a bidentate ligand to one rhenium, and a monodentate ligand to another rhenium atom. The study on the coordination chemistry between trans-[ReOCl3(PPh3)2] and Hbtm gave two different complexes when using different solvents. In ethanol, [ReOCl(btm)(btm1)] formed, whereas [ReOCl(btm1)(btz)] (Hbtz = 1-(benzo[d]thiazol-2-yl)-4-(1-iminoethyl)-3- methyl-1H-pyrazol-5-ol) was isolated in acetonitrile. The reaction of cis-[ReO2I(PPh3)2] also gave two different products when using different solvents, where the respective solvents coordinate to the metal. The rhenium(V) compound [ReO(OMe)(btm)(btm1)] was formed in methanol, whereas [ReO(OEt)(btm)(btm1)] was formed in ethanol. The coordination chemistry of 2-(2-Benzothiazoleyl)-4,5,6,7-tetrahydro-2H-indazol-3-ol (Hbth) was studied towards [Re(CO)5Cl] and trans-[ReOCl3(PPh3)2]. The resulting complexes which formed are [ReCl(Hbth)(CO)3] and [ReOCl(bth)(bth1)] respectively. The reactivity of potentially tridentate Schiff base ligands towards rhenium(I) and (V) was studied. The rhenium(I) precursor [Re(CO)5Cl] was reacted with (E)-1- (benzo[d]thiazol-2-yl)-2-(phenol-2-ylmethylene)hydrazine (H3bph) to give [ReCl(CO)3(H3bph)], which contains the kinetically inert fac-[Re(CO)3]+ core coordinated to a neutral bidentate ligand. The reaction of [ReO2(py)4Cl] with H3bph gave the dimeric species (μ-O)[ReO(Hbph)(py)]2, where the ligand coordinates as a tridentate dianionic chelate. A similar complex was isolated with (E)-1- (benzo[d]thiazol-2-yl)-2-(2,4-dihydroxy-2-ylmethylene)hydrazine (H3bdh) to give (μ-O)[ReO(Hbdh)(py)]2. The reaction of trans-[ReOCl3(PPh3)2] with H3bph afforded [Re(abt)(imp)Cl2(PPh3)] (abt = 2-aminobenzothiazole, imp = 2-(iminomethyl)phenol), where the ligand broke up into two fragments, both of which coordinated without any modification. The dioxo rhenium precursor cis-[ReO2I(PPh3)2] gave [ReO(Hbdh)(imp)] upon reaction with H3bdh. Ligand imp coordinates as a bidentate monoanionic ligand via the imine nitrogen and deprotonated phenolic oxygen and ligand Hbdh coordinatesas a tridentate dianionic chelate.

The former gave a dimeric species (μ-bbi)[Re(CO)4]2 (H2bbi – bisbenzimidazole) by reaction with [Re(CO)5Cl], whereas H2bip produced the rhenium(III) cationic salt [ReCl3(H3bip)(PPh3)]Cl, where the ligand coordinates as a cationic H3bip+ with protonation of an uncoordinated imidazole nitrogen atom. The pyridine derivatives 2-hydrazino-pyridinyl-2-benzothiazole (Hhpt) and (E)-1-benzo[d]thiazol-2-yl)-2- (pyridin-2-ylmethylene)hydrazine (btp) were reacted with [Re(CO)5Cl]. The neutral complex [ReCl(Hhpt)(CO)3] was isolated upon reaction with Hhpt, where Hhpt coordinates as a neutral bidentate ligand. The reaction of [Re(CO)5Cl] with btp gave two different complexes when using different solvents. In methanol, [ReCl(btp)(CO)3] was isolated, whereas in toluene, the conjugate of btp (btp1) was formed which resulted in the formation of [ReCl(btp1)(CO)3]. The study on potentially bidentate thiourea derivatives containing a benzothiazole moiety towards [ReI(CO)3]+ and [ReVO]3+ cores gave rise to a wide variety of complexes.

The reaction of 1-(1,3- benzothiazol-2-yl)-3-benzoylthiourea (Hbbt) with [Re(CO)5Cl] led to the isolation of [ReCl(Hbbt)(CO)3]. Similar reaction of Hbbt with trans-[ReOCl3(PPh3)2] gave the unique compound [ReOCl2(Hbnt)(PPh3)], where the ligand coordinates via the ketonic oxygen and a methine carbon. The complex [Re(Hmby)(mby)(CO)3] was isolated upon reacting [Re(CO)5Cl] with methylbenzothiazol-2-ylidenecarbamodithioate (Hmby), with Hmby coordinating as a monodentate neutral ligand and mby as a bidentate monoanionic chelate. The coordination behaviour of N-(benzothiazol-2-yl)-S,S’- dimethyldithiocarboimine (Hbdc) towards rhenium(I) led to the formation of [ReCl(Hbdc)(CO)3]. The reactivity of 1-(benzothiozol-2-yl)-3,3-dimethylthiourea (Hbdm), a derivative of Hmby, was studied with trans-[ReOCl3(PPh3)2] and trans- [ReO(OEt)I2(PPh3)2] producing the square pyramidal compound [ReOCl(bdm)2] and the salt [Re(bdm)2(MeCN)2]I3, respectively. Pyrazole derivatives containing a benzothiazole ring were studied towards rhenium in oxidation states +I and +V. The reaction between 2-(3,5-dimethylpyrazol-1-yl)benzothiazole (Hdmp) and [Re(CO)5Cl] gave the neutral rhenium complex [ReCl(Hdmp)(CO)3], whereas its reaction with [ReOCl3(PPh3)2] surprisingly results in the formation of a dimeric complex (μ-O)[ReOCl2(Hdmp)]2. The study on the reactivity of 1-(benzo[d]thiazol-2-yl)-4-methyl-1H-pyrrol-2-ol (Hbtm) with [Re(CO)5Cl] gave the unexpected trimer [Re(btm)(CO)3]3 containing the fac-[Re(CO)3]+ core. The ligand btm forms a bridge between each rhenium metal, serving as a bidentate ligand to one rhenium, and a monodentate ligand to another rhenium atom. The study on the coordination chemistry between trans-[ReOCl3(PPh3)2] and Hbtm gave two different complexes when using different solvents. In ethanol, [ReOCl(btm)(btm1)] formed, whereas [ReOCl(btm1)(btz)] (Hbtz = 1-(benzo[d]thiazol-2-yl)-4-(1-iminoethyl)-3- methyl-1H-pyrazol-5-ol) was isolated in acetonitrile. The reaction of cis-[ReO2I(PPh3)2] also gave two different products when using different solvents, where the respective solvents coordinate to the metal. The rhenium(V) compound [ReO(OMe)(btm)(btm1)] was formed in methanol, whereas [ReO(OEt)(btm)(btm1)] was formed in ethanol. The coordination chemistry of 2-(2-Benzothiazoleyl)-4,5,6,7-tetrahydro-2H-indazol-3-ol (Hbth) was studied towards [Re(CO)5Cl] and trans-[ReOCl3(PPh3)2]. The resulting complexes which formed are [ReCl(Hbth)(CO)3] and [ReOCl(bth)(bth1)] respectively. The reactivity of potentially tridentate Schiff base ligands towards rhenium(I) and (V) was studied. The rhenium(I) precursor [Re(CO)5Cl] was reacted with (E)-1- (benzo[d]thiazol-2-yl)-2-(phenol-2-ylmethylene)hydrazine (H3bph) to give [ReCl(CO)3(H3bph)], which contains the kinetically inert fac-[Re(CO)3]+ core coordinated to a neutral bidentate ligand. The reaction of [ReO2(py)4Cl] with H3bph gave the dimeric species (μ-O)[ReO(Hbph)(py)]2, where the ligand coordinates as a tridentate dianionic chelate. A similar complex was isolated with (E)-1- (benzo[d]thiazol-2-yl)-2-(2,4-dihydroxy-2-ylmethylene)hydrazine (H3bdh) to give (μ-O)[ReO(Hbdh)(py)]2. The reaction of trans-[ReOCl3(PPh3)2] with H3bph afforded [Re(abt)(imp)Cl2(PPh3)] (abt = 2-aminobenzothiazole, imp = 2-(iminomethyl)phenol), where the ligand broke up into two fragments, both of which coordinated without any modification. The dioxo rhenium precursor cis-[ReO2I(PPh3)2] gave [ReO(Hbdh)(imp)] upon reaction with H3bdh. Ligand imp coordinates as a bidentate monoanionic ligand via the imine nitrogen and deprotonated phenolic oxygen and ligand Hbdh coordinatesas a tridentate dianionic chelate.

- Description: The dietary habits of the yellow mongoose Cynictis penicillata were studied in the Albany Thicket Biome of South Africa (Great Fish River Reserve, Eastern Cape). The diet was investigated through the analysis of 1,056 scats that were sampled over a period of 7 years (2005−2009 and 2011−2012) mainly in three similar sites (Kelarny, Grasslands and Junction 10) that were used by at least three families or groups of yellow mongooses. Scats were collected near latrine sites, labelled and stored in a freezer. In the laboratory, scats were oven dried for a period of 24 hours at 50 C. Diet was determined by identifying undigested food remains in the scats. Hair samples were examined under the compound microscope to identify which mammals were ingested. In the field, both arthropod and small mammal abundance were determined in order to evaluate whether yellow mongooses are opportunistic or specialist feeders. Furthermore, inter-annual (2006–2008) and inter-group/inter-site variations in the diet were assessed. Based on faecal analysis, arthropods were the principal prey, while small mammals acted as supplementary food item. Other food categories like vegetation, reptiles and birds were only ingested or preyed upon infrequently. Intermediate dietary diversity, and low standardised diet breadth indices were obtained for all seasons, as well as for the whole sampling period. The diet overlaps calculated for pairs of seasons were very high and did not differ substantially. However, the diet of the yellow mongoose varied seasonally, yearly and between groups (sites), mostly due to variations in arthropod and small mammal consumption. Food availability displayed an increase in biomass of both small mammals and arthropods in summer and autumn. Results obtained in this study could suggest that the yellow mongoose at the GFRR is insectivorous by preferring to feed on insects (and arthropods in general) when both insects and rodents are abundant. However the fact that its diet varies both seasonally, yearly and locally, as well as the presence of remains of other food categories in the scats, indicates that this species is rather an opportunistic, generalist feeder than an insect specialist.

- Description: Natural enemies are known to modify competitive hierarchies among terrestrial plants. Here we examine whether the same applies to freshwatersystems. Lagarosiphon major (Hydrocharitaceae) is a submerged aquatic macrophyte, indigenous to South Africa. Outside its native range, it outcompetes with indigenous submerged species and degrades aquatic habitats. Hydrellia lagarosiphon (Diptera: Ephydridae) is the most abundant and ubiquitous herbivore associated with L. major in South Africa and is a potential biological control agent elsewhere. Chaenusa anervata (Hymenoptera: Braconidae: Alysiinae) is its main parasitoid. We generated an experimental system involving one, two or three trophic levels to monitor variation in the competitive ability of L. major relative to that of Myriophyllum spicatum (Haloragaceae), a second submerged macrophyte that can also be invasive. Using inverse linear models to monitor competition, we found that herbivory by H. lagarosiphon greatly reduced the competitive ability of L. major. Addition of the wasp at typical field densities halved the impact of herbivory and reestablished the competitive advantage of L. major. Our results demonstrate how multitrophic interactions modify relative competitive abilities among aquatic plants, emphasize the significance of higher tropic levels in these systems and illustrate how parasitoids can reduce the effectiveness of insects released as biocontrol agents.

- Description: While many executives and senior managers believe that formulating a unique corporate strategy is critical for sustainability and success of an organisation; that alone is not enough. Making sure that the strategic vision is effectively communicated down to lower-level managers and employees is equally as important as formulating corporate strategy. Not only does employees need to understand and believe that senior managers know where they are taking the company to; employees are unlikely to rally behind managerial efforts to get the organisation moving in the intended direction if they do not understand the strategic plans of the organisation. When senior managers articulate a vivid and compelling case for where the company is headed, employees begin to want to be part of the journey, and involve themselves in the implementation of the corporate plans. By effectively communicating the strategic vision of the organisation down to the lower-level managers and employees, senior managers derive support of employees and their commitment to get the company moving in the intended direction. Many organisations or companies in the business world fail, not because they do not have financial resources, not because they do not have a unique and innovative corporate strategy, but because of enforcing or imposing the corporate plans to the employees without selling the company’s plans to its employees, so as to have buy-in from them. This will not only let them be part of the solution, but also feel part of the organisation and take ownership of the organisation’s strategic plans. Strategic plans plays an important role in preparing business organisations to meet their current and future challenges. Research carried out in to both large, medium, small and micro sized-firms constantly emphasise a positive relationship between successful implementation of corporate strategies and its performance. This is because it is often mentioned that well implanted strategies produce outstanding organisational performance. The primary objective of the study was to look at effective communication of corporate strategy in a business organisation and the impact it has on successful implementation of corporate strategy in an Information and Communication Technology (ICT) firm. Various number of studies have been carried out with regard to corporate strategy, but the impact effective communication can have on successful implementation of corporate strategy has never been studied. The study was conducted within an Information and Communication Technology (ICT) firm based in Centurion, Gauteng. It was conducted within an enterprise division of the firm rather than the entire organisation, which employs 400 people. Out of the 400 respondents invited to participate in the study, 98 managed to complete the questionnaires. The study followed a positivistic research paradigm which made use of questionnaires. It made use of an on-line survey where the respondents were invited to participate in the study via e-mails. The study established that certain variables are more critical than other when coming to strategy implementation such as strategic leadership and effective communication.

- Description: This study explored the relationship between management and the union in an Eastern Cape Public Sector Department. The study employed both qualitative and quantitative research tools to collect information from the respondents, who gave a view on their experiences of what the relationship is, and how it could be improved. The sample consisted of members of management and union executives, across employment levels. Both statistical and thematic analysis were used to analyse data from questionnaires and semi-structured interviews. The literature review defined the concept of trade unionism, management and trade union relationship in the workplace, and different frames of reference of the labour relations system. From the literature review it is noted that management and union relationships are more of a formal arrangement in the workplace; as such government, has developed tools to assist in this regard. Although that is not the case in the Department it is noted that the informal arrangement in the relationship between management and union is ‘working’ to some extent. Quality and sustainability of that, however, is questionable. The findings indicate that most members of management acknowledge the existence of the relationship between management and the union, but they are dissatisfied, as most members are not part of the engagements with the union. They are also of the view that it is in favour of the union. Unions on the other hand, view the existing relationship as working in favour of one union instead of the union collective. The union which finds favour is satisfied, and the other is not. It is recommended that the management and union engagement be formalized in order for the Department to work with unions in a more structured, professional manner, which would be inclusive of other members of management who feel left out. Not only that, but management would also be able to engage with the union as a collective, and not as an individual union.

- Description: In this economically challenging era, companies have got to find the best system that can help to enhance productivity. A very important method is by encouraging takeholders through various forms of incentives. The gain-sharing incentive has been adopted by many organisations today to enhance staff loyalty and productivity. A gain-sharing programme ensures that both the organisation and team members benefit from the expected performances, rather than an individual or group incentive which is given based on a specific finite goal which could be achieved at the cost of other key critical business need. A couple of years ago Autocast Aluminium decided to enhance employee performance by initiating the gain-sharing incentive programme. After the programme was rolled out, the organisation is yet to examine the extent to which it enhances job satisfaction in the organisation. The primary objective or aim of the study is to examine the extent to which gain-sharing at Autocast meets the purpose for which it was created. The sample of the study was 176 of the employees at Autocast Aluminium; however 130 questionnaires were distributed. A total of 88 questionnaires were returned, of which 80 were usable, whilst eight were scrapped due to more half of the questionnaire having missing data. This resulted in a 68 % response rate. A framework has been developed to measure to what extent does the programme enable employees to feel satisfied with their jobs. The empirical results revealed that out of six independent variables tested: fair payment, involvement, personal growth, communication, job security and leadership style, only three that plays significant role on employee job satisfaction. These are fair payment, communication and leadership style.

- Description: Zimbabwe is experiencing an ongoing downward spiral in its national economy, dating back to the early 1990s. The demise of the country’s formal economy has led to unprecedented growth in informal economic activities including illegal forms such as sex work. The thesis seeks to understand and explain sex work as a livelihood strategy in Zimbabwe with particular reference to the border town of Beitbridge. In understanding sex work as a livelihood strategy in Beitbridge, the thesis adopts a livelihoods framework in providing key insights into the daily lives of sex workers including the context of vulnerability in which they live and work as well as the challenges they face constantly. In addition, because of the significance of patriarchy in shaping the lives of women and specifically sex workers in Zimbabwe, the feminist theory is used as a secondary theoretical framework. The fieldwork for the study is based on informal interviews and focus group discussions with sex workers as well as observation. Diverse and interrelated themes are covered in examining the livelihoods of sex workers in Beitbridge, and these include sex worker income and expenditure, the motivations underpinning entry into sex work, the home origins of sex workers and their ongoing linkages with their areas of origin, occupational hazards such as client violence and health risks, stigma and discrimination of sex workers, and sex worker solidarity. Though the lives of the sex workers in Beitbridge are marked by precariousness and uncertainty, it is concluded that sex workers are not mere victims of their historical and social circumstances as they are actively engaged in constructing their livelihoods.

- Description: Zimbabwe is experiencing an ongoing downward spiral in its national economy, dating back to the early 1990s. The demise of the country’s formal economy has led to unprecedented growth in informal economic activities including illegal forms such as sex work. The thesis seeks to understand and explain sex work as a livelihood strategy in Zimbabwe with particular reference to the border town of Beitbridge. In understanding sex work as a livelihood strategy in Beitbridge, the thesis adopts a livelihoods framework in providing key insights into the daily lives of sex workers including the context of vulnerability in which they live and work as well as the challenges they face constantly. In addition, because of the significance of patriarchy in shaping the lives of women and specifically sex workers in Zimbabwe, the feminist theory is used as a secondary theoretical framework.

- Description: Automotive component manufacturers face significant competitive challenges in the global market and are constantly looking for means to improve their competitive advantage. Organisations then often acquire lean tools as an attractive option to achieve this. Research has however highlighted that the underlying “Lean Culture” is what is really necessary for organisations to achieve and maintain a competitive advantage. According to Rother (2010) lean implementation can be seen as a project or an initiation of an on- going development process where learning is taking place. This implementation implies a change in organisational culture from its existing state to a state where it reflects a lean culture. The literature review into Lean highlights the importance of establishing a Lean Culture. This research relied on an existing Lean Culture Causal Framework to assess cultural readiness for lean implementation at an automotive component manufacturer in Port Elizabeth (Company X). This was done utilising an empirical study which relied on an existing questionnaire associated with the said Lean Culture Causal Frame work. This Framework focuses on four broad categories of leadership actions; Awareness, Engagement, Consistency and Accountability.
