- Description: Ten sampling sites were selected along the Tyhume River corresponding to the upper, mid and lower reaches of the River. In total 48 families were collected during the study. The study observed different types of macroinvertebrate taxa; very low tolerant to pollution (e.g Heptageniidae; Notonemouridae; Perlidae), moderately pollution-tolerant (e.g. Caenidae; Chlorolestidae; Tricorythidae) and very tolerant of polluted conditions (e.g. Chironomidae; Muscidae; Oligochaetae). Both univariate and multivariate analyses were done using PRIMER V6. Above Confluence (ABCON, Site 10) had the highest number (37) of species while Mtloko (MTLOK, Site 2) had the lowest number (24) (Chi-square = 0.87; p < 0.05). The highest number of individuals (4023) was recorded at Macfairlane (MACFA, Site 5) while the lowest number (1240) at Honeydale (HONEY, Site 8) (Chi-square = 0.00; p < 0.05). Margalef’s index indicated Above Confluence (ABCON, Site 10; 4.762), had the highest values of species richness while Mtloko (MTLOK, Site 2; 3.227) had the lowest values (Chi-square = 1; p < 0.05). Pielou's evenness index indicated that Gqumashe (GQUMA, Site 7) had the highest values (0.7137), while Macfairlane (MACFA; Site 5) had the lowest (0.5109) (chi-square = 1; p < 0.05). Shannon-Wiener diversity indices, the highest diversity index values (2.573) of macroinvertebrates was recorded at Honeydale (HONEY, Site 8), and the lowest (1.684) at Macfairlane (MACFA, Site 5) (chi-square = 1; p < 0.05). The ASPT Scores did not differ significantly (P > 0.05) across sites. No significant difference was observed in the ASPT scores across the 10 sites (F = 0.75; df = 9.60; P > 0.05). Site 4 had the highest mean ASPT Scores with mean of 7.6), whereas the lowest. Three biotopes types, namely: stone, vegetation, gravel-sand-mud, stone and vegetation being the dominant biotopes at the 10 sites. The cluster analyses showed that macroinvertebrates were dependent on biotope preference while stone biotope showing greater macroinvertebrate densities. Euclidean distance of site classification with respect to physico-chemical parameters showed very low stress value (0.01) implying that physico-chemical parameters influenced species distribution within each sampling site. The results also showed that good health conditions existed at the most upstream sites than the lower reaches of the river, thus, indicating impacts of pollution within the river.

- Description: This dissertation is concerned with evolving and extending statistical models in the area of Bayesian spatial modelling, an increasingly important field of spatial epidemiology with particular interest towards application to Tuberculosis data in the Eastern Cape province of South Africa. In spatial epidemiology, the diseases to be examined usually occur within a map that needs spatial statistical methods that are appropriate, to model the observed data in the presence of some covariates and also cater for the variation of the disease. In this thesis, the Bayesian models were developed in such a way that they allowed several factors classified as fixed and random effects, to be included in the models and using the Bayesian approach. The basic model used in disease mapping is the Besag, York and Mollie model, which incorporates two random effects; one which is spatially structured and the other random effect which is spatially unstructured. The effects (fixed and random) were the covariate effects, socio-economic and demographic variability and the spatial variability respectively, which were all investigated in seven different hierarchical/multilevel Bayesian models. These factors showed varying and substantial effects in the posterior relative risk estimation of the disease. We assumed a negative binomial and generalized Poisson distributions to the response variable or relative risk estimate, 𝑦𝑖 ,to capture the over-dispersion phenomenon that is common and inherent with Poisson density for counts data. Spatial and non-spatial models were developed to model over-dispersion with all the distributions; Poisson, negative binomial and generalized Poisson. Negative binomial and generalized Poisson showed varying properties from comparisons with DIC values and parameter estimates to standard errors, which made either of them fit depending on the choice of model selection. It was found that a lower DIC value could be insufficient to determine a best fit model, if other models present estimates with lower variances even at higher DIC values. The generalized Poisson, a two parameter distribution like the negative binomial, which also has the ability to capture both under-dispersion and over-dispersion, was found to perform better in the results than the negative binomial on the basis of a lower variance and with more exact parameter estimates. A new weighted prior distribution, the “Besag2” ICAR model for the structured spatial random effects, which is an extension of the traditional ICAR prior model with two hyperparameters, was also developed and compared with some existing prior models; BYM and ICAR, to measure for spatial dependency in the regions. This new prior distribution was found to show a better fit, when compared to the basic ICAR prior usually assumed for the spatial random effect in the BYM model. This newly parameterized prior distribution in the Besag, York and Mollie model also led to improved parameter control, as the hyperparameters can be seen independently from each other. The result also showed that the new model performed well, both presenting good learning abilities and good shrinkage behaviour. In terms of model choice criteria, the proposed model performed at least equally well and better than the existing models, and the new formulation also gave parameters that are interpretable and have a clearer meaning. To interpolate scattered or regularly distributed data, there are imprecise or exact methods, but there are some of these methods that could be used for interpolating data in a regular grid and others in an irregular grid. Linear and biharmonic spline methods were implemented in MATLAB, to compare for smoothing in the distribution patterns of tuberculosis in the province. This smoothing spline is a method of fitting a smooth curve to a set of noisy observations using a spline function. This new method is rarely used in disease mapping applications, but it has a superior advantage to be assessed at subjective locations rather than only on a rectangular grid as seen in most traditional GIS methods of geospatial analyses. The proposed new models and methods in this thesis were found to be flexible and robust, since they can be reduced or extended according to the nature of the data. Nevertheless, great care must be considered in the choice of prior densities. The approaches developed in this dissertation helped to broaden the scope for spatial analysis and disease mapping applications in epidemiology and public health studies.

- Description: The terrain of local government is not only very complex, dynamic, and challenging, but also very unique. The quality of human resources is vital in a public institution, particularly in institutions that are meant to service communities by providing sustainable basic services. Amongst the concerns raised at a municipal level are the lack of professionalism and the required competency and capacity amongst the workforce that must perform the actual duties of servicing the local communities. This study was aimed at identifying and analysing human resource development and human resource management policies, strategies and needs in line with the current circumstances and conditions at a particular municipality. A series of challenges (that a number of community members, newspaper articles, community leaders and both the Mpumalanga Provincial Government and other spheres of government raised and complained about) prompted this study. Constant complaints are leveled against municipalities about appropriate and well qualified candidates being overlooked for employment opportunities at the expense of nepotism, cronyism and blatant corrupt activities. This study is a combination of both quantitative and qualitative methods. In line with the quantitative method of generating and assembling information, the researcher used the judgement sampling method. Questionnaires were administered to collect quantitative data while primary data was collected via interviews. Data was obtained from 45 participants in Thaba Chweu Municipality. The findings show that the majority of respondents (in the form of percentages) spoke against the capacity of the officials. A smaller percentage spoke in favour of the availability of capacity. These respondents stated that municipal officials have the required skills and capacity to perform their duties. Furthermore, the study found that there was inconsistency in the implementation of council resolutions and interference in administrative matters. These factors compromised achieving the objectives of the municipal strategies and policies. The study recommends that the municipality ensures that the human resource management and development departments are consonant with current and modernised needs and that delegations to line functionaries are properly assigned and documented.

- Description: This study evaluated the carcass and meat quality traits of spent laying hens as influenced by production systems (conventional cages and free range) and the inclusion/exclusion of canola meal in their diets. A total of 30 free range and 60 battery cage reared Lohmann Brown-Elite spent laying hens were obtained from a commercial egg producer. The 30 free range hens (53 weeks of age) and 30 of the caged hens (40 weeks of age) were fed a conventional diet, while the remaining 30 caged hens (48 weeks of age) were fed a diet supplemented with canola meal (20 percent). Carcass, portion and organ weights were determined. Physical attributes and proximate composition were analyzed for, with additional fatty acids and sensory profiles being determined for the effects of canola meal inclusion in the diet. Caged hens had heavier (P ≤ 0.05) warm and cold carcasses, thigh, wing and feet compared to free range hens. The percentages of the breast (26.1 ± 0.51 vs. 28.3 ± 0.28), drum, breast bones, breast thaw and cooking losses and thigh cooking loss were lower (P ≤ 0.05) for caged hens than for free range hens. Free range hens had heavier (P ≤ 0.05) gizzards (33.9 ± 1.04 vs. 30.5 ± 0.73) and bones and a lower (P ≤ 0.05) breast meat percentage (47.3 ± 0.94 vs. 51.7 ± 1.35). Meat redness (a*) (0.54 ± 0.222 vs. 1.40 ± 0.135) and hue angle value, skin redness (a*), breast and thigh, Warner-Bratzler shear force (WBSF) values (breast: 12.37 ± 0.411 vs. 17.10 ± 0.751, thigh: 29.68 ± 0.306 vs. 39.75 ± 0.826), breast moisture and thigh ash content were lower (P ≤ 0.05) for caged hens than free range hens. Caged hens had higher (P ≤ 0.05) thigh thaw loss and breast ash content than free range hens. Canola-fed hens had higher (P ≤ 0.05) drum percentages, breast bone weights and percentages, with lower (P ≤ 0.05) thigh and breast meat percentages. Canola-fed hens had lower (P ≤ 0.05) thaw losses, skin yellowness (b*) and Chroma values, breast fat content with higher cooking losses, skin redness (a*) and hue angle value, as well as breast WBSF (12.37 ± 0.411 vs. 15.43 ± 0.600). Palmitic acid, stearic acid, heneicosanoic acid acid, palmitoleic acid, saturated fatty acids (SFA) (34.0 ± 0.56 vs. 38.7 ± 0.71), n-6:n-3 polyunsaturated fatty acids (PUFA) ratio (5.5 ± 0.13 vs. 7.2 ± 0.28), atherogenic index (IA), thrombogenic index (IT), delta-5 desaturase (D5D, elongase index and thiosterase index were lower (P ≤ 0.05) for canola-fed hen breast meat. Breast meat from conventionally fed hens had lower (P ≤ 0.05) myristic acid, lignoceric acid, nervonic acid, alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), PUFA:SFA ratio (0.7 ± 0.05 vs. 0.9 ± 0.02), n-3 PUFA (3.4 ± 0.31 vs. 5.1 ± 0.17), hypocholesterolemic:Hypercholesterolaemic (h/H), stearoyl-CoA desaturase 16 (SCD16) and stearoyl-CoA desaturase 18 (SCD18). The breast meat from conventionally fed hens had lower (P ≤ 0.05) metallic flavor than that from canola-fed hens. Strong positive correlations were observed for overall aroma with chicken (r = 0.965, P < 0.001) and brothy aroma (r = 0.827, P < 0.001); overall aroma with overall flavor (r = 0.680, P < 0.001), chicken flavor (r = 0.668, P < 0.001) and brothy flavor (r = 0.548, P = 0.006); initial juiciness with sustained juiciness (r = 0.771, P < 0.001) and tenderness (r = 0.537, P = 0.007); sustained juiciness with tenderness (r = 0.790, P < 0.001) and chewiness with residue (r = 0.783, P < 0.001). Whilst strong negative correlations were observed for: sustained juiciness with chewiness (r = -0.655, P = 0.001) and residue (r = 0.783, P < 0.001) and for tenderness with chewiness (r = 0.845, P < 0.001) and residue (r = -0.855, P < 0.001). Results of this study highlight that a free range production system when compared to a conventional cage system increased undesirable carcass and physical meat traits of spent laying hens. On the other hand, canola meal inclusion incorporates beneficial health aspects without affecting the sensory profile of meat derived from spent laying hens, both groups of hens being reared in battery cage system. Spent laying hen breasts can be consumed as a functional food (especially canolafed) since the fat content and composition was observed to be close to that which is recommended for a healthy diet.

- Description: Socioeconomic development is a crucial means of improving standards of living and increasing the incomes of developing countries. This study is premised upon the assumption that the concepts of the developmental state and socioeconomic development are inextricably interrelated. The concept of a developmental state has gained a significant amount of traction in both academic and non-academic circles in recent times. This study took the form of a case study of Rwanda and its developmental trajectory since the country gained independence in 1962. By adopting a historical approach, this study determined that the factors which continue to retard socioeconomic development in post-colonial and post-genocide Rwanda are rooted in a lingering colonial legacy. Although Rwanda has achieved a significant degree of socioeconomic development since 1994, the sustainability of the nascent developmental state which appears to be emerging could still be undermined by ethnic divisions. Accordingly, it was recommended on the basis of the findings of this study that the Rwandan state and its development partners should pursue transformative socioeconomic policies which ensure an equitable distribution of socioeconomic resources, in order to facilitate the creation of an enabling environment for local entrepreneurs and a reduction of dependence upon foreign aid through the effective mobilisation of domestic resources.

This study is premised upon the assumption that the concepts of the developmental state and socioeconomic development are inextricably interrelated. The concept of a developmental state has gained a significant amount of traction in both academic and non-academic circles in recent times. This study took the form of a case study of Rwanda and its developmental trajectory since the country gained independence in 1962. By adopting a historical approach, this study determined that the factors which continue to retard socioeconomic development in post-colonial and post-genocide Rwanda are rooted in a lingering colonial legacy. Although Rwanda has achieved a significant degree of socioeconomic development since 1994, the sustainability of the nascent developmental state which appears to be emerging could still be undermined by ethnic divisions. Accordingly, it was recommended on the basis of the findings of this study that the Rwandan state and its development partners should pursue transformative socioeconomic policies which ensure an equitable distribution of socioeconomic resources, in order to facilitate the creation of an enabling environment for local entrepreneurs and a reduction of dependence upon foreign aid through the effective mobilisation of domestic resources.

- Description: Catalase (EC: 1.11.1.6) is produced by almost all aerobic organism ranging from bacteria to human and is an essential antioxidant enzyme that catalyses the conversion of hydrogen peroxide to water and molecular oxygen, therefore neutralising hydrogen peroxide toxicity. The present study aimed to purify and characterise catalase from Pachymenia orbitosa, a marine red algae found in the Algoa Bay region of South Africa. Bioinformatics analysis was performed to confirm the presence of a catalase gene in the red algae genome. In silico analysis of the Chondrus crispus genome was performed to predict the functional and structural characterisation of the protein encoded by the gene. The Pachymenia orbitosa catalase enzyme was purified to homogeneity using 60% ammonium sulphate precipitation and Sephacryl S-200 gel filtration chromatography. InterProScan confirmed that the Chondrus crispus genome encodes a catalase protein, which is from the mono-functional and heme-dependent catalase-like superfamily. The purified Pachymenia orbitosa catalase enzyme displayed a specific activity of 23 000 units per mg of protein with a 14.94% recovery and 222.91 fold purification. Sodium dodecyl sulphatepolyacrylamide gel electrophoresis indicated a single band, with a molecular weight of around 50kDa. The catalase enzyme exhibited a maximum activity at pH 7 and a temperature of 30℃. It was stable up to 40℃ and rapidly denatured at temperatures above this. The Km and Vmax values for the purified catalase, using hydrogen peroxide as a substrate, were determined from the Lineweaver-Burk plot to be 22.22mM and 1.11x10-4mM.min-1 , respectively, while from the Hanes-Woolf plot, to be 23.4mM and 1.17x10-4mM.min-1 , respectively. The Heme catalase inhibitor (ferricyanide) inhibited the enzyme activity markedly, while sodium chloride and citric acid had only a slight inhibitory effect. Copper sulphate showed a slight stimulatory effect. The physiochemical properties suggest a good application potential in both the pharmaceutical and food industries

- Description: Eastern Cape is one of the provinces experiencing a rapid increase in food prices while household income is increasing at a slower rate. Against this background, the main objective of this study was to investigate strategies used by rural households to improve food security in Raymond Mhlaba Local Municipality formally known as Nkonkobe in the Eastern Cape Province, South Africa. Data were collected from 100 households using a questionnaire as the main instrument by using simple random sampling. Data were analyzed by employing simple descriptive statistics to describe household food security. Results revealed that most (50.3percent) households that were interviewed were male headed and unemployment was high (73.6percent). Moreover, the average age of the interviewed household heads was 59 years. Most (68percent) of the households owned home gardens and had access to arable land which was not being cultivated. Most (87percent) households indicated that lack of capital was the main cause of food security and depended on government grants. Most (100percent) of the interviewed household heads depend mostly on food purchases rather than their own production. The recommendation is that the government should continue fostering its agenda of improving agriculture as a strategy in rural households for curbing food insecurity.

- Description: Approximately 2-4 billion cases of infectious diarrhoea occur every year, with the highest numbers recorded in sub-Saharan Africa. It remains the most common public health issue among children in developing nations. The purpose of this research was to unfold the prevalence of diarrhoeagenic E. coli and Campylobacter pathotypes as well as elucidate their antibiogram characteristics in diarrhoeal stool samples collected in some medical facilities in Eastern Cape Province, South Africa. Two hundred stool samples were collected from both inpatients and outpatients from male and females of all age groups attending selected medical facilities in the study area. Isolation and characterization of both organisms were done using culture based and molecular methods. Antibiotic susceptibility patterns of identified isolates were determined against a panel of 12 antimicrobial agents. One hundred and twenty presumptive E. coli isolates and 42 presumptive isolates of Campylobacter spp. Were isolated. Eighty-two percent (82 percent) of the presumptive E. coli isolates were confirmed as E. coli while 46.3 percent belonged to Campylobacter spp. Pathotyping of the diarrhoeagenic E. coli isolates by Polymerase chain reaction (PCR) showed the following prevalences: DAEC 43 (32 percent), EHEC 18 (17 percent), EIEC 11 (10 percent) and EPEC 18 (17 percent). EAEC and ETEC were not detected, while for Campylobacter spp. 37 (88 percent) were C. jejuni, and C. coli was not detected. A total of 12 (32.4 percent) of the confirmed Campylobacter jejuni isolates were found to possess the fliM gene, 9 (24.3 percent) possessed the flhA gene and only 6 (16.2 percent) harboured the gene flgE2. None were positive for the flaA, flab and flhB genes.The antibiotic resistance patterns observed among the E. coli isolates were high against ampicillin (98.1 percent), chloramphenicol (94.3 percent) and tetracycline (90.6 percent). For Campylobacter spp., resistance observed were: chloramphenicol (91.6 percent), tetracycline (25.2 percent), erythromycin (49.6 percent) and gentamycin (56.4 percent). A lesser resistance against imipenem (35.9 percent) and quinolone (ciprofloxacin) (45.5 percent) were exhibited by the E.coli isolates. 10.8 percent and 20.3 percent of the Campylobacter isolates were resistant to imipenem and ciprofloxacin respectively. The presence of chloramphenicol (CatA1) and tetracycline (tetA) resistance genes were detected in 94 percent and 89 percent of E. coli isolates respectively while 98 percent of Campylobacter spp. Harboured the catA1 resistance gene. It could be deduced from this study that E. coli and Campylobacter spp. are predomiant enteric pathogens as the etiologic agents of diarrhoea in the study community, and that their antimicrobial resistance is high in the study location. The need to develop strategies to prevent infection and control resistant organisms is evident.

- Description: The climate is changing, with imminent threats. Projections for increased inconsistencies in climatic elements such as rainfall and temperature have continued to raise concerns particularly amongst farmers. The majority of South African smallholder and resource-poor farmers rely heavily on rain-fed agriculture, making them vulnerable to the vagaries of climate change risks. As sustainability is crucial to the continuous survival of this population, this study assessed the farmers’ perceptions of climate change impacts on agricultural production activities as well as their adaptation responses. The South African national climate change response policy was developed and approved in October 2011 in order to institute a responsive intervention system for the moderation of climate change impacts on South Africa’s citizens. Amongst its priorities is building capacity and resilience in the country’s agricultural sector, with the public agricultural extension system as a principal component for climate change sensitisation, education and capacity-building. With current global climate change conditions, the urgency to provide agricultural knowledge on adaptation has risen. Smallholder farmers, in particular, are challenged in this regard, and face numerous restraining factors. Therefore, this study investigated several key issues related to climate change sensitization activities and response. A multistage sampling procedure was used in the selection of the study sample (n = 301) residing in the rural settlements of Mbahashe Local Municipality, in Amathole District Municipality, Eastern Cape Province, South Africa. A cross-sectional household survey was carried out in eighteen villages surrounding the three major towns in the municipality – Idutywa, Elliotdale and Willowvale. Data was collected using semi-structured questionnaires. Descriptive and inferential statistical tools were used for data analysis. Findings revealed a perceived increase in temperature levels and a drastic decline in rainfall; perceived harsh and aggressive climatic conditions, with attendant problems of drought. There is a perceived increased difficulty in production activities as a result of water scarcity. Poor soil conditions, pest infestations and disease infections, poor vegetation and limited grazing, decreased livestock growth rate, reduced livestock weight, milk production and reproduction rates, reduction in quantity of egg production, egg quality and sizes, are amongst many other perceived challenges. There is a growing threat of unsustainable agricultural production, which may in due course increase poverty levels among the smallholder farmers. Adaptation responses were extremely limited. Findings also revealed that there is an extremely low awareness of the national climate change response policy, and a dearth of sensitisation campaigns and capacity-building training of smallholder farmers in the study area. There is also a significant lack of access to agricultural extension services that might disseminate information and build capacity for an appropriate climate change response. Analysis also revealed that public extension services play a minute role in rural farmers’ climate change knowledge; they get their information elsewhere. The most critical constraint to climate change coping and adaptation in the study area was lack of access to agricultural extension services. The study recommends government intervention in the form of appropriate, functional extension services, particularly for carrying out climate change coping and adaptation education and support. It also strongly endorses the tower gardening concept, practised in a number of countries, including parts of South Africa to facilitate an exigent intervention project to curb declining crop production and sustain the livelihoods of farmers, before major intervention schemes are set up by various governing bodies. There is an immense need to buffer the adaptation capacities of livestock smallholder farmers in rural communities through the implementation of adaptation promotional schemes for rural livestock sustainability. Productivity and efficient commercialization of both indigenous and hybrid poultry production should be beefed up by encouraging poultry breeding programs and breed improvement activities, subsidizing commercial feeds to encourage supplementary feeding, provision of better infrastructure for improved housing and the facilitation of health care systems like vaccination programs. This study also recommends that efforts to create awareness, knowledge and skills in relation to climate change be intensified through an enhanced use of all media. In addition, agricultural extension departments functioning at the local level should be financially and technically capacitated to allow for enhanced performance by their field officers.

- Description: This study seeks to look at play as an indicator of public opinion in online political commentary of online news forums leading to the 2014 South African general elections. A qualitative content analysis was used to analyse viewers’s comments about 2014 South African general elections posted online. The concepts of critical discourse analysis, frame analysis play theory and network analysis were applied to extend and inform the study. A corpus of all commentary appended to 2014 South African general election news reports published online by Media24, Times Media Group, Mail &Guardian, Independent Newspapers, Caxton CTP, and TNA Media were selected. The study employed a purposive sampling technique and 1000 comments were extracted. The sample began four weeks before the election and ended two weeks after the event. NVIVO 11 was utilized to code these readers’ comments into their respective categories. The core findings of this thesis reflect that online readers do not just engage in play but are more interactive and participative on these online public forums and their political discourse echo political affiliations with different political parties, bearing in mind that South Africa has 13 political parties that participated and are represented in parliament. In addition, the findings revealed that, play cannot be parted with and remains inseparable with "what is real"; instead, play renews the real world by giving it sense and meaning. Play does not "re-present" nor falsify certainty but it enunciates certainty. The findings also revealed that most participants identify themselves with the ANC as the ruling party, the DA as the main opposition, the EFF as the most vocal party and then other parties. The findings further revealed that participants have different perspectives on different economic and socio-political matters such as, entertainment, slate politics, and political affiliation, cadre deployment, political bias, economic meltdown, diaspora, and western influence, abuse of power by those in high places, land reform programme, political power struggles, leadership change and corruption.

- Description: The Eastern Cape Province have high numbers of livestock but high poverty rates remain very high. This study therefore, aimed to determine the contribution of smallscale livestock farming to rural household income in the King William’s Town area in five rural areas. Literature shows that the livestock sector contributes 40 percent of global value of agricultural output and supports the livelihoods and food security of almost a billion people. The data collected for this research were both quantitative and qualitative and cross-section design was employed for the research. The study used both simple random sampling and availability sampling to select 125 sample households, 25 respondents from each village. Descriptive statistics was used in the analysis of demographic and socio economic characteristics of households where graphs and tables were used to present the relevant information. Probit regression model was used to determine factors influencing the decision to practice livestock production and marginal analysis was calculated to determine the effect of changes of individual variables. For the assessment of the contribution of small-scale livestock farming to household income Propensity Score Matching (PSM) model was fitted. Results show that the highest percentage of livestock kept by households in 5 villages is 56 percent for poultry and the lowest percentage is 2 percent for pig. The main source of income for many households in the study area was the income from pensions and grants but livestock farming is also contributing to household’s income through income generated from sales of livestock for customary events such as traditional rituals and celebrations, lobola, funerals and weddings. Many of the households have secondary education and the reason might simply be that in olden days’ parents had no money to pay school fees of their children and that limited children to go further with their studies. The results of the marginal effects estimates for the probit model suggest that changes in the number of livestock sold would have important effects on household incomes. There are various challenges that livestock producers are facing in their production and the major challenge that households are facing is parasites and diseases as they decrease number of livestock kept by households. Parasites and diseases suck blood, causing the animals to become weak and sometimes resulting in high mortality rate. It is recommended that livestock producers should be made aware of the impacts of various challenges that affect livestock farming through awareness creation programmes and suggest solutions to overcome those challenges.

- Description: Small-scale fisheries are known to provide food and income to millions of people around the world, but their role and existence is often ignored in development planning. The growing human demand for animal protein has become one of the foremost world challenges for which aquatic organisms have a significant role to play. In South Africa, small-scale fisheries have been recognized since the end of Apartheid, but the extent of the contribution of the sector to rural livelihoods and food security is not well understood. Using data drawn from a sample of 80 fishers in the coastal community of Hamburg, Eastern Cape, this dissertation presents an assessment of the contribution of small-scale fisheries to rural livelihoods, income and food security. The primary data were collected from the fishers using a structured questionnaire and non-probability sampling. The data were analysed with the assistance of descriptive techniques and a few simply statistical tests. The results of the study indicate that fishers in Hamburg catch a wide range of fish, which include wild kob, octopus, spotted grunter, white/black mussel cracker and white steenbras. Fishers in the study area are not solely dependent on small-scale fisheries for their livelihoods, income and food security, but generally supplement their welfare payments with fishing in order to sustain their livelihoods. About 78percent of the surveyed fishers depend on government grants, including old age grants, child support grants and social care grant. In terms of employment, 15percent of the surveyed fishers are casually employed, while 6percent are formally employed on a contract basis. Although they are not only dependent on fishing, nevertheless fishing is an important source of livelihood, income and food security. About 37percent of the fishers harvest marine resources for home consumption, while 7percent harvest solely for income, and 56percent harvest for both home consumption and income. Income generated from fisheries is approximately R935 per month and is used to buy food, electricity, fishing equipment and other household needs. The findings from this research underline the need for interventions such as coordinated institutions, improved infrastructure, improved monitoring and enforcement systems, as well as improved access to permit/fishing rights for sustainable use of marine resources.

- Description: The objective of the study was to determine the effect of feeding graded levels of Moringa oleifera leaf meal powder (MOLP) on growth performance, carcass characteristics, economic analysis, health status, physicochemical, sensory properties, mineral composition and retention values of meat. A total of 1600 Comb-500 day-old unsexed chicks were allotted to 4 dietary treatment groups, with 4 replicate pens of 100 birds each in a completely randomised design. The dietary treatments were basal diets supplemented with different levels of MOLP as follows; Treatment 1/ control: Basal diet with antibiotic Zinc bacitracin and coccidiostatic Maxiban and no MOLP (0MOLP); Treatment 2: Basal diet included 1percent MOLP (1MOLP); Treatment 3: Basal diet included 3.0 percent MOLP (3MOLP); Treatment 4: Basal diet included 5 percent MOLP (5MOLP). Birds fed basal diets plus 5percent MOLP at starter phase achieved the least FCR 1.53 (P < 0.037), whilst consuming significantly less feed ADFI 47.4 g (P < 0.05). For the entire feeding period, birds fed 5 percent MOLP achieved a favourable FCR of 1.80 among all treatment groups (P < 0.001), but achieved the lowest final live weight (1416 g), carcass weights (1044g) (P < 0.05). Birds fed 0 percent MOLP recorded highest final weight, carcass weight (1339) and the best dressing percentages (76.8percent) (P < 0.05). Abdominal fat levels were reduced by elevating MOLP in diets (P < 0.05). Improvements in proportions of giblets, gizzard, liver and intestine were observed with increase in dietary MOLP. Feed costs increased, while gross and net returns and economic efficiency decreased as dietary MOLP increased. Organ indices of spleen, Bursa of Fabricius and liver were significantly increased by 5percent MOLP in the diet (P < 0.05). Macroscopic lesions scores (P < 0.05) were significantly higher in duodenum, jejunum and ileum of birds in the 1MOLP treatment group on d 28 and d 35. Control and 5MOLP groups recorded the least bloody excreta scores among all treatment groups (P < 0.05). Highest total aerobic bacteria (TAB), E. coli, C. perfringens counts and the lowest lactobacillus spp counts were observed in all intestinal segments in birds in the 1MOLP treatment group. Lower E. coli and C. perfringens but higher lactobacillus spp counts were observed in control and 5MOLP groups (P < 0.05) in the duodenum and jejunum. Increasing MOLP levels in diets led to lower pH and pHu in both breast and leg muscles (P < 0.05). pH was consistently lower in leg muscles than in breast cuts in all treatments and a large decline in post-mortem pH was observed in all muscles of birds in control group. A dietary increase in MOLP level led to a significant increase in L* and b* (P < 0.05) negative correlation between pH and L* (r = -0.463) (P < 0.05) and a weak but significant (P < 0.001) correlation (r = 0.176) between pH and drip loss. Herb flavour (P = 0.0029), appearance (P = 0.0156), aroma (P = 0.0011), colour (P = 0.0375), taste (P = 0.0032) and overall acceptability (P = 0.0192) were improved by grilling, microwave cooking and pan-frying in olive oil. These changes were more pronounced in breast muscle, thus following the trend; microwave > pan-frying in olive oil > grilled samples > boiling for best cooked product based on overall acceptability. Grilling and frying heart muscles resulted in the highest Ca (45.9 mg/kg) and Mg (98.9 mg/kg), whereas boiling led to the lowest Ca (41.1 mg/kg) and Mg (91.4 mg/kg) concentration. The highest concentrations of Fe and Zn these minerals were recorded in grilled (32.7 mg/kg) and fried samples (75.2 mg/kg). Zinc and Fe concentration observed in liver and heart muscles were higher than those found in breast and leg muscle. In conclusion, the results confirm the potential of MOLP for use as an alternative to antibiotics in maintaining broiler health, reducing mortalities and improving carcass characteristics and some meat quality traits.

- Description: Orientation: Technology affects organisations both positively and negatively and in some instances technology factors can result in turnover intentions for certain employees of organisations. Research purpose: The main objective of the study was to investigate how technology-based job autonomy, technology-based job overload and technologybased job monitoring impact turnover intentions of employees. Motivation of the study: Exploring and understanding the relationship between technology factors and turnover intention amongst government employees to determine whether these factors affect government as much as they affect the private sector. Research design, approach and method: This research used a quantitative research approach. It drew a convenience sample of 182 employees (N= 182) from the South African Government. Main findings: The three main findings of the study were: Technology-based job autonomy was positively related to turnover intention. Technology-based job overload was found to be positively related to turnover intention. Finally, technology-based monitoring was found to be positively related to turnover intention. Practical/managerial implications: If organisations do not address the issue of monitoring and overload they are likely to experience many turnover intentions amongst the employees. Furthermore, the organisations with less autonomy are likely to lose their employees which means they will lose the resources that have been serving the organisation for a long time. This will also contribute to the organisation losing many funds as they would constantly have to train new employees. Contribution/value-add: The research adds value to the knowledge about the effects of technology factors on turnover intention by pointing out the reasons that lead to turnover intention.

- Description: The National Health Insurance is a relatively new concept in South Africa currently being piloted to ensure that all citizens have access to quality and affordable health care regardless of their socio-economic status. This study was prompted by concerns regarding the introduction of the NHI and its implications on the South African health system. Therefore it seeks to determine the professional nurses concerns about the introduction of the NHI in a private hospital in Gauteng and to describe recommendations based on these perceptions. This study used a qualitative, exploratory and descriptive design. Data was collected using a semi-structured individual interview schedule. The sample was purposive consisting of professional nurses employed in a private hospital in Gauteng. Thematic data saturation determined the number of professional nurses interviewed. Data analysis was done with the aid of Creswell’s theory (2014:1996). Ethical considerations were observed and trustworthiness maintained. The results of the study outlined that professional nurse’s perception about the NHI is centred on equal distribution of health services to benefit all South Africans. However, concerns were based on its financial implications for those mandated to pay towards the fund. The feasibility of its implementation in the midst of staff shortage, inadequate resources and its impact on the public health sector was seen as a major challenge. The notion of a joint effort between public and private health sector in creating one health system was anticipated by most participants. The NHI implementation raised concerns about the impact it will have on the private sectors viability in the future. Professional nurse’s non-involvement in policy making, poor communication, lack of transparency, concerns about governance and management were perceived to be stumbling blocks towards efficient and effective implementation of the NHI.

- Description: Economic globalisation entails the integration of national economies into one economy centred upon free International trade and the unrestricted flow of foreign direct investment.1 It has been argued by economists, politicians, business people, lawyers and many others that economic globalisation results in healthy competition amongst producers of goods and technologies around the world. This in turn results in market efficiency, cheaper, high quality goods and the increased spread of technology and wealth amongst countries. International trade aims to increase trade liberalisation, which has been seen to create higher standards of living for people as a result of greater competition amongst producers in different parts of the international globe. However whilst in support of trade liberalisation trade lawyers have warned that International trade must be fair. Unfair trade can take the form of dumping, price fixing, and certain methods of subsidisation. Unfair trade usually has disastrous effects on the domestic markets of importing countries which can result in injury to domestic industry and the national economy. Such injury can be in the form low sales, losses, company closures and retrenchments. As a result of such domestic injury, World Trade Organisation (WTO) law condemns dumping if it causes injury to the domestic industry of the importing country2 and allows importing countries to impose certain measures aimed at protecting themselves against such injury; these measures are called anti-dumping measures. However, WTO member states need to ensure that their anti-dumping frameworks are consistent with WTO norms. The principal objective of this study is to critically assess the existing regulatory framework of anti-dumping in South Africa with a view to identifying shortcomings that may result in the framework being inconsistent with WTO anti-dumping rules. In pursuing that objective, the study explores the norms and standards of the existing WTO regulatory framework on anti-dumping and ascertains the obligations of South Africa with regard to the imposition of anti-dumping measures.

- Description: The Republic of South Africa is embedded from a society that has been beleaguered. Apartheid laws were used to treat people unequally, based on race, gander, ethnic group, background, colour, belief, culture and language. These laws prohibited association of people from different races and groups. The education system was also used to instil inferiority to disadvantaged people. This system promoted a culture of secrecy and unresponsive government. The new Constitution of the Republic of South Africa was adopted in 1996. This Constitution promotes democracy and equality amongst citizens of this country. It was also adopted to bridge injustices of the past. Democracy is about allowing every citizen to participate in the processes which are meant for the development of the country. The new Constitution provided that every citizen is equal; this means every citizen must enjoy equal human Rights. This includes the Right to participate in democratic processes which are taking place. Studies show that the Right of Access to Information empowers people to participate in democratic processes. This study examines the exercise in section 32 of the Republic of South Africa Constitution (1996), by Zwelitsha community as means to empower people in participating in democratic processes taking place in their community. This Right is reinforced by Promotion of Access to Information Act No. 2 of 2000 (PAIA). The research reveals that the community of Zwelitsha is not exercising this Right which often leads to violation of other Rights. The exercise of the Right of Access to Information increases awareness and knowledge of other existing Rights, and how they can be realised and defended. The recommendations in the study underscore the need to promote the Right of Access to Information as a means to empower citizens to participate in the democratic processes in their community. This study will take the community a step closer to reaching equality. It will also educate the community of the need and importance of exercising the Right of Access to Information. It will assist the community to be able to protect other Rights. An informed community is an empowered community that can also hold the state to account.

- Description: The aim of the study was to determine the effect of assisted reproductive technologies (ARTs) in improving cattle production with the purpose of providing policy directives for the successful implementation of the ART project among communal and emerging livestock systems. The study was conducted under communal and emerging cattle farming systems in Limpopo, Mpumalanga and KwaZulu-Natal provinces. The selected districts in Limpopo were Vhembe, Capricorn, Mopani and Waterberg, in Mpumalanga were Gert Sibande and Ehlanzeni while in KwaZulu-Natal the selected districts were Zululand and Harry Gwala. A total of 282 cows were selected for the study, 38 percent in Limpopo, 32 percent in Mpumalanga and 30 percent in KwaZuluNatal. The cow parameters evaluated were breed type, parity, age, body condition score, frame size and lactation status. An ovsynch protocol which allows for fixed-time artificial insemination (FTAI) was used during the oestrous synchronisation process. A heat mount detector (Karma®) was used to detect oestrous synchronisation response. The dominant cattle breed types were the Bonsmara, Brahman and Nguni. All experimental cows that responded positively to oestrous synchronisation protocol and were inseminated with semen from a Nguni bull. Chi-Square Test of Independence were computed to determine the association among factors. Data was further modelled using the logistic regression model of SAS, establishing the probability of success. Districts, breed type, parity, age, and lactation status did not significantly influence (P > 0.05) conception rate following oestrous synchronisation and timed artificial insemination. However, conception rate was not independent (P < 0.05) of provinces, body condition score and body frame size. Cows in KwaZulu-Natal (66 percent) had significantly higher (P < 0.05) conception rates than those in Limpopo (44 percent) and Mpumalanga (60 percent). Cows of body condition score of ≥ 3.5 (72 percent) had a significantly higher (P < 0.05) conception rate than those of body condition score of ≤ 2.5 (66 percent) and 3 (48 percent). Large (82 percent) framed cows had a significantly higher (P < 0.05) conception rate than small (49 percent) and medium (55 percent) framed cows. Cows in Mpumalanga had more chances to conceive than those of Limpopo and KwaZulu-Natal with odds ratio of 0.605 and 0.863, respectively. Cows in KwaZulu-Natal were in much better body conditions than those from the other two provinces. Cows of body condition score of ≥ 3.5 had more chances to conceive than those of body condition score of ≤ 2.5 and 3 with odds ratio of 0.592 and 0.388, respectively, and the difference was significant (P < 0.05). The study recorded a 100 percent calf survival rate following synchronisation and timed artificial insemination. The breed type, parity, age frame size and lactation status did not significantly influence calving response following oestrous synchronisation and timed artificial insemination (P > 0.05). However, calving rate was not independent of provinces, districts and body condition score (P < 0.05). Calving rate in Mpumalanga (58 percent) and KwaZulu-Natal (54 percent) was significantly higher (P < 0.05) than that recorded in Limpopo Province (36 percent). Calving rate of Gert Sibande (61 percent) and Ehlanzeni (50 percent) districts in Mpumalanga and Zululand (50 percent) and Harry Gwala (61 percent) in KwaZulu-Natal was significantly higher (P < 0.05) than that of the Capricorn (32 percent), Mopani (23 percent and Waterberg (30 percent) in Limpopo Province with the exception of Vhembe (44 percent). Cows with body condition score of ≤ 2.5 (60 percent) had a significantly higher (P < 0.05) calving rate than those with a body condition score of 3 (43 percent). Cows in Mpumalanga had more chances to calve than those in Limpopo and KwaZulu-Natal with odds ratio of 0.076 and 0.537, respectively. Additionally, quantitative data was collected through in-depth interviews using a semi-structured questionnaire. Data collected was managed and coded into themes using the Nvivo Version 11 software programme. Themes and issues that emerged were analysed and interpreted using critical social thinking and systems thinking. The results of the study revealed many factors that could compromise the implementation and adoption of ARTs in the study areas. The general feeling amongst cattle farmers interviewed was that government should address these challenges. A shortage of bulls was the main cause of the low cattle reproduction rate. The Nguni breed type cattle was perceived as the ideal cattle breed for rural areas by respondents. Oestrous synchronisation and artificial insemination can be applied under communal and emerging farming systems with success. From the study results, breeding with small framed animals such as the Nguni type breed under communal and emerging farming systems makes a lot of sense because the breed is known for its low feed maintenance requirement. Furthermore, cattle stakeholders should co-operate and work together to address many of the constraints facing cattle productivity and the implementation and adoption of ARTs in rural areas.

- Description: The aim of the study was to determine the effect of assisted reproductive technologies (ARTs) in improving cattle production with the purpose of providing policy directives for the successful implementation of the ART project among communal and emerging livestock systems. The study was conducted under communal and emerging cattle farming systems in Limpopo, Mpumalanga and KwaZulu-Natal provinces. The selected districts in Limpopo were Vhembe, Capricorn, Mopani and Waterberg, in Mpumalanga were Gert Sibande and Ehlanzeni while in KwaZulu-Natal the selected districts were Zululand and Harry Gwala. A total of 282 cows were selected for the study, 38 percent in Limpopo, 32 percent in Mpumalanga and 30 percent in KwaZuluNatal. The cow parameters evaluated were breed type, parity, age, body condition score, frame size and lactation status. An ovsynch protocol which allows for fixed-time artificial insemination (FTAI) was used during the oestrous synchronisation process. A heat mount detector (Karma®) was used to detect oestrous synchronisation response. The dominant cattle breed types were the Bonsmara, Brahman and Nguni. All experimental cows that responded positively to oestrous synchronisation protocol and were inseminated with semen from a Nguni bull. Chi-Square Test of Independence were computed to determine the association among factors. Data was further modelled using the logistic regression model of SAS, establishing the probability of success. Districts, breed type, parity, age, and lactation status did not significantly influence (P > 0.05) conception rate following oestrous synchronisation and timed artificial insemination. However, conception rate was not independent (P < 0.05) of provinces, body condition score and body frame size. Cows in KwaZulu-Natal (66 percent) had significantly higher (P < 0.05) conception rates than those in Limpopo (44 percent) and Mpumalanga (60 percent). Cows of body condition score of ≥ 3.5 (72 percent) had a significantly higher (P < 0.05) conception rate than those of body condition score of ≤ 2.5 (66 percent) and 3 (48 percent). Large (82 percent) framed cows had a significantly higher (P < 0.05) conception rate than small (49 percent) and medium (55 percent) framed cows. Cows in Mpumalanga had more chances to conceive than those of Limpopo and KwaZulu-Natal with odds ratio of 0.605 and 0.863, respectively. Cows in KwaZulu-Natal were in much better body conditions than those from the other two provinces.

- Description: The perspective of South African liberation history needs to be balanced by recalling events that might otherwise be overshadowed by the subsequent electoral dominance of the African National Congress since 1994. This study is concerned with one such: the Cofimvaba struggles of 1962-3 which was organised by Cofimvaba migrants under the ideology of the Pan Africanist Congress. Whereas previous historians have based their accounts mainly on trial records, this thesis strives to recover the migrants’ own perspective through intensive and detailed interviews with the surviving veterans. It aims to provide an accurate historical account of the role played by migrant labourers, thereby correcting the historical distortions arising from overreliance on official sources to record the memories and perceptions of the struggle veterans, as exemplified by transcripts of interviews with and thereby provide some balance to the overall perspective of South African liberation history. The thesis opens with a description of the situation on the ground in Cofimvaba and Western Thembuland which gave rise to resistance. It continues with a discussion of the Pan-African Congress, especially in the Western Cape, the labour centre where most Cofimvaba migrants were concentrated. It proceeds to a detailed narrative of the events in Cofimvaba, more especially the battle of Ntlonze. The final chapter concludes with a critical reassessment of previous historical work, showing that the role of the migrants and the non-elite require greater appreciation and respect.

- Description: The church as a unique society was founded by Jesus Christ who also set a pattern for its operations. Primary to the core responsibilities of the church, according to Scripture, is to reconcile creation to the Creator by transforming society to regain its lost nature. The Christian Church in Kenya was established by missionaries from different parts of the world about three centuries ago. It has since grown and spread to almost all the parts of the country, but all the major denominations have vibrant congregations in Nairobi. A quick categorisation of the church in Kenya would be into the Mainline and the Pentecostal churches. This study set out to investigate the perception the church in Nairobi holds on in its involvement in social action, whether the church thinks social action is part of its ministry, and what kind of engagements in social action the church in Nairobi is currently having. The study employed a qualitative approach and an exploratory design. Using the questionnaire and interview methods, data was collected from thirty two (32) church leaders (including pastors) sampled to be representative of the Mainline and the Pentecostal groups of churches. The data was transcribed, coded, categorised and interpreted following the themes which emerged in relation to the study objectives and the nature of the responses. The results of the study show that the church holds different perceptions on its responsibility and involvement with regard to social action. The findings show two extremes: those who see social action as core to the mission of the church and those who think social action is the responsibility of the government or of non-governmental agencies. Generally most churches do not plan or budget for social actions. The few that are engaged in in it the budgets are far too low compared to the other church activities and the plans are unstructured and sporadic Active engagement in social action by the church in Nairobi is therefore, by and large, unplanned and episodic. However, the few who are already engaged in social action have witnessed great success in community transformation. The study concludes that the church has not fully understood its ministry and this could be the reason why social action is not part of its agenda. This further explains the sporadic and truncated nature of social action in the church in Nairobi. The study recommends a review of the curriculum in seminaries and the retraining of practising pastors to embrace holistic ministry. This will address the current misconceptions, address the current dichotomy of sacred-secular in church ministry, and hence increase organised participation of the church in social action.
