- Description: Vibrio infections remain a serious threat to public health. In the last decade, Vibrio disease outbreaks have created a painful awareness of the personal, economic, societal, and public health costs associated with the impact of contaminated water in the aquatic milieu. This study was therefore designed to assess the prevalence of Vibrio pathogens in the final effluents of wastewater treatment plants (WWTPs) in the Eastern Cape Province, as well as their abilities to survive the treatment processes of the activated sludge system either as free cells or as plankton-associated entities in relation to the physicochemical qualities of the effluents. Three wastewater treatment facilities were selected to represent typical urban, sub-urban and rural communities, and samples were collected monthly from August 2007 to July 2008 from the final effluent, discharge point, 500 meter upstream and downstream of the discharge points and analysed for physicochemical parameters, Vibrio pathogens prevalence and their antibiogram characteristics using both culture based and molecular techniques. Physicochemical parameters measured include pH, temperature, electrical conductivity, salinity, turbidity, total dissolved solid (TDS), dissolved oxygen (DO), chemical oxygen demand (COD), nitrate, nitrite and orthophosphate levels. Unacceptably high levels of the assayed parameters were observed in many cases for COD (<10 - 1180 mg/l), nitrate (0.08 - 13.14 mg NO3- as N/l), nitrite (0.06 - 6.78 mg NO2- as N/l), orthophosphate (0.07-4.81 mg PO43- as P/l), DO (1.24 - 11.22 mg/l) and turbidity (2.04 -159.06 NTU). Temperature, COD and nitrite varied significantly with season (P < 0.05), while pH, EC, salinity, TDS, COD, and nitrate all varied significantly with sampling site (P < 0.01; P < 0.05). In the rural wastewater treatment facility, free-living Vibrio densities varied from 0 to 3.45 × 101 cfu ml-1, while the plankton-associated Vibrio densities vary with plankton sizes as follows: 180 μm (0 – 4.50 × 103 cfu ml-1); 60 μm (0 – 4.86 × 103 cfu ml-1); 20 μm (0 – 1.9 × 105 cfu ml-1). The seasonal variations in the Vibrio densities in the 180 and 60 μm plankton size samples were significant (P < 0.05), while the 20 μm plankton size and free-living vibrios densities were not. Molecular confirmation of the presumptive vibrios isolates revealed V. fluvialis (36.5 percent), as the predominant species, followed by V. vulnificus (34.6 percent), and V. parahaemolyticus (23.1 percent), and V. metschnikovii (5.8 percent) (detected using only API 20 NE), suggesting high incidence of pathogenic Vibrio species in the final effluent of the wastewater facility. Correlation analysis suggested that the concentration of Vibrio species correlated negatively with salinity and temperature (P < 0.001 and P < 0.002 respectively) as well as with pH and turbidity (P < 0.001), in the final effluent. Population density of total Vibrio ranged from 2.1 × 101 to 4.36 × 104 cfu ml-1 and from 2.80 ×101 to 1.80 × 105 cfu ml-1 for the sub-urban and urban communities treatment facilities respectively. Vibrio species associated with 180 μm, 60 μm, and 20 μm plankton sizes, were observed at densities of 0 - 1.36 × 103 cfu ml-1, 0 - 8.40 × 102 cfu ml-1 and 0 - 6.80 × 102 cfu ml-1 respectively at the sub-urban community‘s WWTP. In the urban community, counts of culturable vibrios ranged from 0 - 2.80 × 102 cfu ml-1 (180 μm); 0 - 6.60 × 102 cfu ml-1 (60 μm) and 0 -1.80 × 103 cfu ml-1 (20 μm). Abundance of free-living Vibrio species varied between 0 and the orders of 102 and 103 cfu ml-1 in the sub-urban and urban communities WWTPs respectively. Molecular confirmation of the presumptive vibrios isolates revealed the presence of V. fluvialis (41.38 percent), V. vulnificus (34.48 percent), and V. parahaemolyticus (24.14 percent) in the sub-urban community effluents. In the urban community V. fluvialis (40 percent), V. vulnificus (36 percent), and V. parahaemolyticus (24 percent) were detected. There was no significant correlation between Vibrio abundance and season, either as free-living or plankton-associated entities, while Vibrio species abundance correlated positively with temperature (r = 0.565; P < 0.01), salinity and dissolved oxygen (P < 0.05). Turbidity and pH showed significant seasonal variation (P < 0.05) in both locations. The Vibrio strains showed the typical multi-antibiotic-resistance of an SXT element. They were resistant to sulfamethoxazole (Sul), trimethoprim (Tmp), cotrimoxazole (Cot), chloramphenicol (Chl) and streptomycin (Str), as well as other antibiotics such as ampicillin (Amp), penicillin (Pen), erythromycin (Ery), tetracycline (Tet), nalidixic acid (Nal), and gentamicin (Gen). The antibiotic resistance genes detected includes dfr18 and dfrA1 for trimethoprim; tetA, strB, floR, sul2 blaP1, for tetracycline, streptomycin, chloramphenicol, sulfamethoxazole and β-lactams respectively. A number of these genes were only recently described from clinical isolates, demonstrating genetic exchange between clinical and environmental Vibrio species. This study revealed that there was an adverse impact on the physicochemical characteristics of the receiving watershed as a result of the discharge of inadequately treated effluents from the wastewater treatment facilities. The occurrence of Vibrio species as plankton-associated entities confirms the role of plankton as potential reservoir for this pathogen. Also the treated final effluents are reservoirs of various antibiotics resistance genes. This could pose significant health and environmental risk to the biotic component of the environment including communities that rely on the receiving water for domestic purposes and may also affect the health status of the aquatic milieu in the receiving water. There is need for consistent monitoring programme by appropriate regulatory agencies to ensure compliance of the wastewater treatment facilities to regulatory effluent quality standards.

- Description: Even though agriculture is the backbone of Malawi‟s economy, food insecurity has remained a continuous threat among the poor. Until the 1980s, Malawi had been achieving national food security through an extensive system of agricultural inputs and marketing subsidies. However, these subsidies were removed and at the same time, the agricultural credit system collapsed. Consequently, agricultural productivity in Malawi remained low, poverty remained pervasive and food insecurity remains a main constraint to national and household food security. Therefore, the success of the agricultural sector in Malawi is very critical for raising the living standards and for food self-sufficiency. In this vein, the study hypothesized that Malawi can only achieve sustainable agricultural development if its agricultural policies are focused towards intensifying agricultural productivity through active participation of smallholder farmers. The major aim of the study was to contribute towards an improved understanding of how the issues of sustainable agricultural development have been addressed in Malawi and how they have influenced the lives of smallholder farmers. The analysis of the results revealed that even though what was implemented in the 1970s to early 1980s was financially unsustainable, but it provided some solutions to the fundamental challenges of smallholder development in Malawi. However, the liberalisations eroded whatever economic benefits achieved then. Never the less, the re-introduction of the agricultural input subsidies restored back the means of production leading to significant transformation of the country from a net importer to a net food exporter. On the other hand, although the agricultural input subsidy programme is being commended for having helped in achieving food security, the study revealed that the programme requires complementary services of credit, extension, research and market to support it. This will provide an exit strategy, which can enable the producers to sell their produce at higher prices sufficient enough for them to afford agricultural inputs without subsidies.

- Description: This dissertation investigates the effects of the financial crisis on the South African economy. In order to do this, an index which describes the financial conditions of the South African economy is constructed and computed. The index indicates that domestic South African financial conditions have deteriorated substantially during the period under study and so the study investigates how this has impacted on the country’s economic growth. A VAR model with South African variables is specified and used to assess the quantitative effects of the financial crisis on South African real GDP growth. Results suggest that the South African economy was not significantly affected by the crisis, but economic growth was slowed down and may still grow substantially slower in the next few years due to the financial crisis. These results corroborate the theoretical predictions and are also supported by previous studies.

- Description: This study investigates the impact of ICTs for agricultural development in the Alice rural community. The rationale for carrying out the study has to do with the limited access to ICTs by farmers residing in this rural community which in turn affects their productivity and increase in the volume of agricultural production. The core argument of the study is that the use of ICTs has positive spinoffs on agricultural development which leads to improvement in the quality and quantity of agricultural production. Conversely lack of access to ICTs can result in inability to enhance agricultural productivity in rural areas such as Alice. Furthermore, it is argued herein that technological information devices such as ICTs are essential communication and information tools; and as such, should be regarded as useful communication media for disseminating relevant agricultural information to farmers residing in rural communities. In conducting this study theoretical frameworks such as Rogers’ diffusion of innovation and development theories encompassing both the participatory approach and development support communication were presented and argued for as approaches suitable for the study. Triangulations of research methods, such as, qualitative and quantitative methods, were utilized for the collection of data for this study. As is common practice, the triangulation method was used in cross checking and supplementing data/information collected through the utilization of each of the methods. Interviews and questionnaires were used as data collection tools for this study owing to their ability to generate clear and precise responses or answers to the questions posed. The key findings of the study show that the limited access to ICTs in the Alice rural community was caused by factors such as low level of literacy, age and language barriers which in turn affected the adoption of ICTs amongst the Alice farmers. Amongst the recommendations emanating from this study is the idea that the adoption of ICTs for agricultural information can be fast-tracked through the implementation of telecentres/kiosk and information centers for easy access to information and communication services in the rural community.

- Description: This thesis examines the extent and nature of the impact of the contextualization of Christianity upon the amaXhosa from the missionary irruption in the nineteenth century to the present day, and proceeds to examine the implications of this impact for the presentation of the Christian gospel in the contemporary Eastern Cape. Chapter One describes the problem, offers definitions of key concepts and outlines the procedural method for the rest of the thesis. Chapter Two deals with the question of the cross-cultural communication of the Christian gospel in theory. Doctrinal questions such as the nature of the gospel are examined. The basic hermeneutical issue of the categorization of doctrinal tenets according to whether they are required or simply permitted is discussed in terms of Osborne's categories: 'cardinal', 'non-cardinal'. Tenets which are found to be 'anti-scriptural' would be rejected. Specific hermeneutical topics such as language and meaning, symbolics, textuality and orality are then discussed. This is followed by a survey of secular influences which affect a conceptualization. This chapter is preparatory to, and definitive for, the discourse which follows. Chapter Three outlines the cultural heritage from which the Western missionary contextualization of Christianity developed. It shows the extent to which this presentation of the gospel was dependent upon the philosophy which Britain and Europe inherited from the classical Greek culture. More modern developments such as the Enlightenment, Empiricism and Historicism bring the discourse up to the point at which the missionaries arrived. Chapter Four deals with the initial encounter between the missionaries and the amaXhosa. A brief account is given of the nature of the religious and spiritual aspects of the Xhosa culture which first encountered Christianity. The doctrinal section of this chapter deals with those doctrines in the missionary message which became issues for the amaXhosa. The hermeneutical section shows how the cultural setting of the West (vii) affected both the contextualization by the missionaries and the conceptualization by the amaXhosa. To a large extent, the missionaries made the double mistake of imposing their culture on the amaXhosa and failing to accord respect, even recognition, to the Xhosa culture. This amounted to imperialism, which, together with the political imperialism of Britain as the colonizing power, evoked responses from the Xhosa community which are outlined in section 4.4, including those of Nxele and Ntsikana. Because the impact of the Western contextualization is an on-going phenomenon, the thesis continues to trace its development up to the present time. Apartheid is briefly mentioned in Chapter Five. The point is made that all white people were perceived by the amaXhosa to be Christians, and the architects and practitioners of apartheid claimed to be Christians. This ideology therefore had a direct effect on the Xhosa conceptualization of the gospel. The architects of apartheid actually believed that they were accepting God's gift and mandate. This chapter includes Black theological reaction to apartheid in terms of the South African version of Liberation theology. Chapter Six returns to Western Theology in order to bring the sphere of discourse from the point at which it left off at the end of Chapter Three up to the present time. The schools of thought in this period are: Secularism and Existentialism, together with their theological extension, Demythologization. The main religious movements are the Charismatic Movement and Neo-Pentecostalism. Postmodernism came as a later philosophical school, to be followed by Globality. Chapter Seven deals with black South African reactive and proactive responses. The predominant theologies are those of Dwane, Buthelezi, Boesak and Mtuze. Although Dwane, Buthelezi and Boesak came on the scene at the same time as the black theologians reviewed in Chapter Five, their work is placed here because it differs significantly from the more radical responses of the latter. Mtuze is post-apartheid, and responds to the developments outlined in Chapter Six. Chapter Eight draws the findings of the thesis together, by considering how the Christian Gospel ought to be presented to the various contemporary sub-cultures of the amaXhosa. (viii) The last Chapter applies the findings of the thesis to the task in hand. The desired outcomes are listed and briefly discussed. The task ahead is enunciated in terms of manpower and other resources for the effective communication of the Christian gospel in the twenty-first century. The past, present and projected programmes of the Bible Institute Eastern Cape [the target institution] are described and assessed. Finally, topics which presented themselves in the course of the preparation of this thesis are suggested for future research.

To a large extent, the missionaries made the double mistake of imposing their culture on the amaXhosa and failing to accord respect, even recognition, to the Xhosa culture. This amounted to imperialism, which, together with the political imperialism of Britain as the colonizing power, evoked responses from the Xhosa community which are outlined in section 4.4, including those of Nxele and Ntsikana. Because the impact of the Western contextualization is an on-going phenomenon, the thesis continues to trace its development up to the present time. Apartheid is briefly mentioned in Chapter Five. The point is made that all white people were perceived by the amaXhosa to be Christians, and the architects and practitioners of apartheid claimed to be Christians. This ideology therefore had a direct effect on the Xhosa conceptualization of the gospel. The architects of apartheid actually believed that they were accepting God's gift and mandate. This chapter includes Black theological reaction to apartheid in terms of the South African version of Liberation theology. Chapter Six returns to Western Theology in order to bring the sphere of discourse from the point at which it left off at the end of Chapter Three up to the present time. The schools of thought in this period are: Secularism and Existentialism, together with their theological extension, Demythologization. The main religious movements are the Charismatic Movement and Neo-Pentecostalism. Postmodernism came as a later philosophical school, to be followed by Globality. Chapter Seven deals with black South African reactive and proactive responses. The predominant theologies are those of Dwane, Buthelezi, Boesak and Mtuze. Although Dwane, Buthelezi and Boesak came on the scene at the same time as the black theologians reviewed in Chapter Five, their work is placed here because it differs significantly from the more radical responses of the latter. Mtuze is post-apartheid, and responds to the developments outlined in Chapter Six. Chapter Eight draws the findings of the thesis together, by considering how the Christian Gospel ought to be presented to the various contemporary sub-cultures of the amaXhosa. (viii) The last Chapter applies the findings of the thesis to the task in hand. The desired outcomes are listed and briefly discussed. The task ahead is enunciated in terms of manpower and other resources for the effective communication of the Christian gospel in the twenty-first century. The past, present and projected programmes of the Bible Institute Eastern Cape [the target institution] are described and assessed. Finally, topics which presented themselves in the course of the preparation of this thesis are suggested for future research.

- Description: This study examines the experiences of the school management teams and educators of the Isibane Circuit in the Queenstown District, regarding the implementation of an Integrated Quality Management System (IQMS) policy at school level. Following an agreement reached in 2003 between the South African Education Department and the major teacher organisations in this country, the IQMS was scheduled to be implemented in public schools from 2004. Two major challenges are identified and explained: accountability and development of human resources, as well as contradictions between internal and external evaluations. The study also elaborates on the changes in the educational history from the apartheid system to the democratic system of education. Nine schools participated in the study (two secondary schools and seven primary schools). These schools were purposely selected due to the fact that they had started implementing the IQMS policy, which was the main criterion for selection. Semi-structured interviews were used to gather data from principals, Heads of Departments as well as post-level one educators concerning their experiences of the IQMS implementation. The findings indicated that while the IQMS policy was good on paper, it was extremely difficult to implement. Issues of honesty and trust were at the root of difficulties that made the IQMS implementation challenging. The participants‟ understanding of IQMS was that it was intended for the provision of quality education and development.

- Description: This study focuses on the role of discipline in the establishment and maintenance of a safe school environment for learners and educators. In a mainly qualitative investigation, empirical data from four primary schools and five high schools in the East London Region of the Eastern Cape Province were collected by means of individual interviews and questionnaires. Historico-legal research also formed part of the literature review, thus law reports and articles from South Africa and other countries were included as part of the research process. This was done to shed light on the legal consequences of school violence and discipline, affecting the safe learning environment of learners. Perceptions of educators and learners in the selected schools regarding discipline and violence at their schools were collected by means of a survey. Three hundred and thirty questionnaires were completed by learners from the selected schools, and nine interviews were conducted with either the principal or a member of the senior management team of each school. The researcher also conducted further in-depth interviews with twenty learners from four schools (two primary and two high schools). These data were analysed in accordance with accepted procedures for qualitative data processing. The data revealed that a culture of violence exists in these schools, and that corporal punishment is still practised. Learners’ perceptions on safety and discipline at their schools revealed that bullying persists, especially when there is no teacher supervision. Participating educators’ experiences suggested the need for promoting positive discipline, and creating a safe learning environment for all, by involving parents in the education process and involving them in drawing up a code of conduct for the school.

- Description: Small and medium enterprises (SMEs) are very important to employment creation, poverty alleviation and the sustainable economic development of a nation. Encouraging SMEs, especially start-ups is crucial for sustainable economic growth. However, the failure rate of start-up SMEs in South Africa is one of the highest in the world. In reviewing the literature of the causes of the failure of start-up SMEs, access to finance emerged as a prime challenge. Start-up SMEs find it very difficult to obtain external finance from commercial banks and venture capitalists. The national and provincial governments in South Africa have realised that access to finance is a major constraint to the growth and survival of start-up SMEs and have put in place certain measures to improve access to finance by start-up SMEs. One of the primary measures put in place by government to improve access to finance by start-up SMEs is the provision of Business Development Service by some government agencies. This research investigates the role of Business Development Services Providers (BDSs) in improving access to finance for start-up SMEs. Questions arise as to why the failure rate of start-up SMEs is high in South Africa despite all these government measures aimed at assisting start-ups to access finance. Empirical research was conducted to investigate the role of BDS in improving access to finance by start-up SMEs. The instrument used for data collection was the self-administered questionnaire. The statistical analyses included descriptive statistics, T-test, ANOVA, correlation and regression analysis. The Cronbach‟s alpha was used as a measure of reliability. The results of the study revealed that: Access to finance is still a major problem hindering the survival of start-up SMEs. There is a lack of awareness of BDS providers and their services by the majority of start-up SMEs. There is a significant positive relationship between the use of BDS by start-up SMEs and success in accessing finance. Start-up SMEs that are aware of BDS do make use of the services. The results suggest that BDS are important to improving access to finance by start-up SMEs. However, there is a need to build awareness and encourage the use of BDS by start-up SMEs to improve their access to finance and ultimately increase their chances of survival.

- Description: Intensive tillage and monoculture cropping practices reduce soil C accumulation hence increasing soil vulnerability to chemical, physical and biological degradation. This study focussed on enhancing biomass production of wheat and oat winter cover crops as a means of increasing C sequestration in the low organic C soils of the central part of Eastern Cape Province. The specific objectives were (i) to evaluate the short-term effects of no till and cereal-fallow based crop rotations on; soil organic matter related parameters, pH and electrical conductivity, (ii) soil bulk density, water retention and aggregate stability, (iii) soil microbial biomass C and N, mineralizable N, soil respiration, and dehydrogenase enzyme activity, (iv) grain yield, soil nutrient concentration (N, P and K) and their uptake by maize, and (v) to identify soil parameters with high sensitivity to tillage under maize-fallow-maize, maize-wheat-maize and maize-oat-maize rotational cover cropping practices. The experiment was laid out as a split-plot arrangement in a randomized complete block design with 4 replicates. Tillage treatments (CT and NT) were applied on the main plots which measured 8 × 18 m while crop rotation treatments were applied in the subplots which measured 8 × 6 m. The rotation treatments were maize-fallow-maize (MFM), maize-wheat-maize (MWM) and maize-oat-maize (MOM). Weed control in NT plots involved preplant application of glyphosate to control mainly the grass weeds while post emergence weed management was done using Atrazine (485 atrazine and 15 g l-1 triazines). Initial weed control in CT plots was achieved through ploughing to a depth of 20 cm followed by disking while post emergence weed iii management was done by hand hoeing. Soil parameters measured were; (i) particulate organic matter (POM), soil organic carbon (SOC), total nitrogen (TN), pH and electrical conductivity (EC), (ii) soil bulk density (b), moisture at field capacity (FC), aggregate mean weight diameter (MWD) determined by fast wetting (FW), slow wetting (SW), mechanical breakdown by shaking (MB) and the stability index (SI), (iii) soil microbial biomass C (MBC) and N (MBN), mineralizable N (MN), soil respiration (SR), and dehydrogenase enzyme activity (DHEA). No-till increased POM and TN compared to CT in Lenye and Burnshill, respectively. The MWM and the MOM rotations increased TN relative to the MFM rotation in Lenye. The MWM and MOM rotations enhanced SOC relative to MFM in all sampled soil depths at Burnshill and similar observations were made under MOM rotation in the 5-20 cm depth in Lenye. The MWM and MOM rotations tended to depress soil pH relative to the MFM rotation in both sampled soil depths in Lenye while NT reduced soil pH relative to CT on the surface soil layer in Burnshill. Soil EC and pH varied with depth across tillage practices but both parameters remained within the ideal range for successful crop production over the study period. Soil stability index (SI) and aggregate MWD determined by FW, SW and MB were higher in Lenye compared to Burnshill. The MOM rotation enhanced the SI relative to MFM and MWM rotations at both sites. Scanning electron microscope (SEM) showed that more organic C was incorporated into the soil under NT and MOM rotation compared to CT and MFM rotation which had few organic coatings on the soil particles. Microbial properties varied with plant biomass input as influenced by tillage and type of rotational cover crop at both sites. Like in other past studies, NT showed higher levels of MBC, MBN, NM and SR at the soil surface layer compared to CT in Burnshill. No till increased MN iv relative to CT in both sampled soil depths in Lenye and resulted in higher DHEA compared to CT in Burnshill. The MOM rotation increased MBC, MBN, MN relative to MFM rotation especially within surface soil layer. Similar observations were made with respect to MN and SR in both sampled soil layers at Lenye. By contrast, the DHEA was higher under the MFM relative to the MWM and MOM rotations in Lenye but similar under the MFM and MOM rotations in Burnshill. Maize grain yield was not affected by both tillage and crop rotations but varied with cropping season. Comparable grain yields observed under the two tillage practices with similar fertilizer application rates indicated the advantage of NT over CT in saving on labour costs in maize production without compromising yields. High plant biomass retention under NT relative to CT contributed to high soil N and P levels under the former compared to the latter tillage practice especially on soil surface layer at both study sites. Principal component analysis (PCA) revealed that soil chemical and biological parameters closely linked to organic matter, namely SOC, MN, MBC and MBN showed the highest sensitivity to tillage and crop rotation treatments. Soil aggregate MWD determined by SW and b were the physical parameters which were highly altered by agronomic management practice. The MWM and MOM rotations were clustered together and clearly separated from the MFM rotation and this observed trend only applied to the 0-5 and 5-20 cm depths in Lenye site only. No till, MWM and MOM rotations enhanced POM, SOC and TN relative to CT and MFM rotation suggesting these practices have greater potential to improve soil chemical properties compared to intensive tillage and maize monoculture based production practices. Reduced soil b under MOM rotation and improved SI under NT compared to MFM and CT, respectively v indicate that these practices have the potential to improve degraded soils. Although not significantly different, NT values for MBC, MBN, MN, SR and DHEA were higher compared to CT indicating the potential of the practice to improve soil biotic activity relative to conventional tillage practices. No till enhanced surface soil nitrate N and extractable P compared to CT at both sites revealing the long-term potential of NT in improving the supply of these essential plant nutrients compared to CT. Principal component analysis showed that SOC, MN, K, P, MBC, MBN, soil aggregate MWD determined by SW and b were the most sensitive parameters to tillage and crop rotations. Therefore, these parameters could constitute the minimum data set for assessments of the impact of selected CA practices on soil quality attributes.

- Description: Time budgets, avoidance distance scores-related behaviour and milk yield of pasture-based Jersey, Friesland and crossbred cows. by Madodana Sunson Dodzi The study was conducted at the University of Fort Hare farm to determine the time budgets, the avoidance-related behaviour variables and their relationship with milk yield in three pasturebased dairy genotypes: Jersey, Friesland and crossbreed. Twenty one clinically health dairy cows aged between 52 and 55 months, in mid lactation and comprising of seven cows from each genotype were used in the study. The time spent on different activities (grazing, lying down, standing and others) at pasture was recorded using stop watches across four seasons. The behavioural responses of the three genotypes to humans were determined by recording their avoidance distance scores (AD), exit speed (ES), pen scores (PS), pen behaviour scores (PBS), plat form scores (PLS) and the occurrence of kicking (KCK) and stepping (SPG) during milking on four consecutive days in four seasons. Time spent standing was higher (P < 0.05) for Friesland compared to Jersey and crossbred during the hot-wet season. In the cool-dry season the Jersey spent more time (P < 0.05) grazing than the other breeds. The Friesland and crossbred on the other hand devoted most of their time lying down compared to Jersey in the cool- dry season (P < 0.05). There were season differences in time spent on all activities (P < 0.05). Time spent on grazing was longest in post-rainy seasonal and lowest in hot- wet season (P < 0.05). The longest lying down period was observed in the hot-dry season and lowest in hot-wet season (P < 0.05). iii Daily milk yield Varied (P < 0.05) with genotype with the Friesland and Jersey producing higher yield than the crossbred. The highest amount was produced in hot-dry and the least in hot-wet season. Milk yield was positively correlated (P < 0.05) with lying down. Standing was negatively correlated with milk yield (P < 0.05). The Friesland had the highest avoidance distance scores (P < 0.05) and the Jersey had the lowest avoidance distance scores in all seasons. There was an association (P < 0.05) between genotype and exit speed scores, pen scores and stepping behaviour scores. The Friesland exhibited the highest exit speed scores than the other breeds. The Jersey had the lowest (P < 0.05) kicking behaviour scores. There was a relationship (r = 0.64) between avoidance distance scores and exit speed. Exit speed scores were correlated with pen score(r= 0.23). Milk yield was significant related (r= 0.17) to the occurrence of kicking behaviour. The genotypes showed different levels of sensitivity to season and milk yield was influenced by breed and season. It can be concluded that time budgets vary with season and farmers need to adopt measures that buffer the effect of season on welfare of dairy cows. It can also be concluded that avoidance distance scores differs according to genotype with Jersey being more confident to humans than other two breeds. It is therefore recommended that provision of shades or cooling mechanism should be adopted to buffer the effects of hot-wet season. Improving quality of feed during the cool-dry season may be critical for Jersey cows. Finally positive handling of the dairy cows is recommended in order to improve the welfare and milk yield of pasture based dairy cows.

- Description: Time budgets, avoidance distance scores-related behaviour and milk yield of pasture-based Jersey, Friesland and crossbred cows. by Madodana Sunson Dodzi The study was conducted at the University of Fort Hare farm to determine the time budgets, the avoidance-related behaviour variables and their relationship with milk yield in three pasturebased dairy genotypes: Jersey, Friesland and crossbreed. Twenty one clinically health dairy cows aged between 52 and 55 months, in mid lactation and comprising of seven cows from each genotype were used in the study. The time spent on different activities (grazing, lying down, standing and others) at pasture was recorded using stop watches across four seasons. The behavioural responses of the three genotypes to humans were determined by recording their avoidance distance scores (AD), exit speed (ES), pen scores (PS), pen behaviour scores (PBS), plat form scores (PLS) and the occurrence of kicking (KCK) and stepping (SPG) during milking on four consecutive days in four seasons. Time spent standing was higher (P < 0.05) for Friesland compared to Jersey and crossbred during the hot-wet season. In the cool-dry season the Jersey spent more time (P < 0.05) grazing than the other breeds. The Friesland and crossbred on the other hand devoted most of their time lying down compared to Jersey in the cool- dry season (P < 0.05). There were season differences in time spent on all activities (P < 0.05). Time spent on grazing was longest in post-rainy seasonal and lowest in hot- wet season (P < 0.05). The longest lying down period was observed in the hot-dry season and lowest in hot-wet season (P < 0.05). iii Daily milk yield Varied (P < 0.05) with genotype with the Friesland and Jersey producing higher yield than the crossbred. The highest amount was produced in hot-dry and the least in hot-wet season. Milk yield was positively correlated (P < 0.05) with lying down. Standing was negatively correlated with milk yield (P < 0.05). The Friesland had the highest avoidance distance scores (P < 0.05) and the Jersey had the lowest avoidance distance scores in all seasons. There was an association (P < 0.05) between genotype and exit speed scores, pen scores and stepping behaviour scores. The Friesland exhibited the highest exit speed scores than the other breeds. The Jersey had the lowest (P < 0.05) kicking behaviour scores. There was a relationship (r = 0.64) between avoidance distance scores and exit speed. Exit speed scores were correlated with pen score(r= 0.23). Milk yield was significant related (r= 0.17) to the occurrence of kicking behaviour.

- Description: This study explores women’s access to land under the customary tenure system. It examines how the changes in land tenure, access and rights to land as a consequence of HIV/AIDS are affecting agricultural productivity, food security and poverty, with a specific focus on women who have lost their husbands to HIV/AIDS in Zvimba. Zvimba is a village community located in Zvimba District in the Mashonaland West Province of Zimbabwe. The study also discusses policy responses designed to cushion the impact of HIV/AIDS on local communities especially women living with HIV/AIDS. The study highlights the vulnerability of widows to land rights violations, mainly inflicted by relatives but sometimes by the wider community. The main form of abuse encountered included the use of abusive language, threats of evictions and at times, beatings. The legal route for seeking redress was rarely used. Fear of witchcraft, low educational levels and fear of causing conflict between children and their paternal relatives also led widows to abandon the fight for their rights. The study further reveals that widows are heavily exposed to dispossession of their land rights. HIV/AIDS has increased the vulnerability of widows and other women to threats and dispossession of their land and other property rights. Dispossession of arable fields was observed in the four wards. The dispossessions and threats to livelihoods were directly related to the HIV positive status of the widows. The findings from this study illustrate the predominant role that male members of the household or family have over land. Thus, culture and traditional practices still affect women in other cases, disadvantaging them in favour of men, as in inheritance of land and property in the household.

- Description: The core argument in the study is that there have been little prospects of housing delivery in Nkonkobe Municipality. The obstacles for housing development in this area are embedded in the inflexibility of current policies and legacies of the colonial as well as the Apartheid era. Furthermore, the findings indicate that local as well as external sociopolitical practices such as lack of funding, unavailability of land, corruption, politicking, lack of community participation, impact of macro-economic policy, planning and lack of capacity seem to hamper the process of housing delivery. Hence, there is a need for an alternative development strategy which is adopted as the conceptual framework of this study. This is to enhance housing development in most rural areas. This conceptual framework propounds that housing provision in Nkonkobe region should be enhanced in the context of empowerment, nation-building and democratization in the post-Apartheid South Africa. The problem of housing has become a worldwide phenomenon. Compared to other countries, the number of people in need of adequate shelter has remarkably increased and in South Africa the number of people who live in substandard housing and those in desperate need of shelter is enormous. However, in the study a view of housing provision in post-Apartheid South Africa is advocated through looking at the nature of the state and its capacity to deliver quality housing service. A qualitative methodology comprising in-depth interviews and observation was employed in order to gain a deeper understanding of the effectiveness of the municipality in delivering quality service to its people. The ideological perspectives view historical causes and present day reasons for the perpetuation of the housing problem from different angles. A strategy based on alternative development is proposed in this study. The conceptual framework views the poor as active people engaged in the production of their own lives not passive recipients of state development projects. An underlying assumption is that housing provision is influenced by previous state forms and spatial practices. Therefore, the level of community participation could influence the success of housing development projects. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2009

- Description: Biofuels are currently recognized as not only a necessity, but an inevitable pathway to secure the planet future energy needs. Food crops have been used (so far) as the biomass for bioethanol and biodiesel production. This has increased concerns over food security and led to the search for diversification and alternative feedstocks for biofuel production. The use of lignocellulosic materials, the most abundant, low cost and easy feedstock to harvest for bioethanol purpose, involves challenging production processes. Several approaches have been used to facilitate the breakdown of the biopolymer structure to produce fermentable sugars that can be converted to ethanol. Most of the approaches have used high temperatures and pressures and have often led to the production of inhibitors of fermentation. In this study, lignocellulosic materials from grass and newsprint were investigated as sources of biomass for bioethanol production using a chemical route (sulfuric acid hydrolysis) which made use of temperatures below 100°C at normal atmospheric pressure. Fermentation of toxic lignocellulosic hydrolyzates was possible after the development of a method for inhibitors removal. The method used treated wood chips as a stationary phase in a chromatographic column to remove inhibitors. This method is expected to be extended to applications such as in municipal wastewater treatment. Sugar yields of 22.26 and 8.9 g/L of hydrolyzate; and an ethanol yield of 184.5 and 130.4 mg/mL of must were achieved for 5g grass and newsprint respectively using optimum conditions of 2percent H2SO4 at 97.5°C for grass and 0.5percent H2SO4 at 97.5°C for newsprint during the hydrolysis process. Pure cellulose was used as a control for the biomass where 254.1 g/L of fermentable sugars were recovered from soluble cellulose and the yield of ethanol was 201.8 mg/mL. , Thesis (MSc) -- Faculty of Science and Agriculture, 2009

Terms like "slams","slaamaaier" and "halfnaatjie" (Roos 2003:3) were just a few of the derogatory names that was awarded to the Cape Malay. Many of these terms and identity constructions are in the South African literature immortalized. The true history, the struggle, tears and sacrifices of this community slipped by unnoticed and in silence. And today, after all this suffering, they become identity is called into question and this identity is referred to as a controversial identity. In the Western Cape this identity mainly centered around being Malay, being Coloured, Being Cape Muslim or Black Muslim. It seems as if the Cape Malay is in an intermediate identity (defined in English as "inbetweenness") are trapped, defined by their "Muslimness","Cape-ness", "Malay-ness" and "Coloured-ness". This dissertation examines the controversy of the Cape Malay identity and focus specifically on identity construction and Otherness. It emphasizes certain characteristics that people divided due to certain character traits that are different from the norm and therefore cause that they are considered the Other. The study is undertaken with the aim of establishing the authenticity of the Cape Malay identity state and how it is depicted in the works of selected South African writers. It intends to look specifically at the construction of identity through Otherness during the colonial period in Southern Africa as well as how these identities were implemented, rejected or accepted is. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2009

- Description: Communal rangelands are the main source of livestock feed for resource poor communal farmers. They are characterized by heavy stocking and poor management which is perceived to be the cause of the prevalent degradation hence the incessant calls for introduction of rotational grazing. Rotational grazing has been associated with improved rangeland condition and animal performance in commercial farms, hence the call that it needs to be introduced in communal areas. Management of communal rangelands within the rotational grazing context requires some fundamental understanding of the relationship between current rangeland use, socio-economic and ecological factors determining the present use of these areas. The objective of this study was to assess how historic tenure and patterns of use have influenced grazing practices and institutional structures, and to identify institutional and ecological factors determining present grazing strategies. Focus group discussions and questionnaire surveys in 11 communities revealed that villagers consider fences and paddocks as the best intervention to improve range management. Furthermore, it was shown that lack of strong local-level institutions, little or no knowledge of veld management, absence of rules and lack of seasonal restrictions on rangeland resource use are additional constraints that need to be considered for any rotational grazing intervention to be embraced. Communal areas vary in household head profiles, and this affects the livestock ownership patterns, which indirectly influences rangeland management. The fact that most of the income for communal area people is from state grants, makes farming secondary and the attention put on rangeland management would therefore be minimal. At present the weak local level institutions would therefoe make any plans to introduce rotational grazing difficult. Communal area grazing strategies are further influenced by rangeland heterogeneity caused by different factors. To understand these factors, the relationship between vegetation parameters in different patches and associated soil parameters was examined. Heterogeneity due to seasonal variation in the biomass of herbaceous vegetation was observed at Magwiji‘s sweetveld, with frequently selected patches having a significantly (p < 0.05) higher biomass in autumn (791 kg ha-1) and winter (528 kg ha-1), while in summer and spring there was no significant (p > 0.05) difference in biomass between frequently selected and less selected patches. The present situation in which communal areas support large livestock populations under continuous grazing is due to the fact that cattle would adjust to changes in forage availability by seeking higher biomass patches in times of forage scarcity as observed in Magwiji. At the coastal forest thornveld of Mnyameni the Canonical Correspondence Analysis (CCA) showed that the first axis was significantly correlated with soil organic carbon (r = -1, p < 0.05). Furthermore, the species that were significantly correlated with the first axis were Cynodon dactylon and Pennisetum clandestinum. These species were mainly found in sites that were preferred in April and June. At the sourveld of Upper Mnxe the first axis was significantly correlated with soil pH (r = 0.9, p < 0.05). At this rangeland, sites selected in June were associated with alkaline soils; characterized by a history of human settlement and dominated by Eragrostis superba and Heteropogon contortus. Soil electrical conductivity (EC) separated species (r = 0.9; p < 0.05) along the first axis at Magwiji, with mountain top sites selected in April and June having low EC and dominated by Digitaria eriantha, Eragrostis superba and Andropogon appendiculatus. Rangeland heterogeneity is caused by various factors, ranging from human disturbance to topography. These factors have an effect on the soil properties, and therefore, vegetation and thus lead to the observed heterogeneity which shapes the utilization patterns of these rangelands, and hence their continued support of large populations of livestock. To understand the effects of seasonal and spatial variation in resource use pattern and implications on range management, differences in cattle activity patterns in relation to veld type, season, daytime, management type (kraaling) and forage quality were examined. Seasonal activity patterns were only significant at Upper Mnxe (p < 0.05), with percent of time spent grazing (77 percent), resting (35 percent) and walking (24 percent) being higher in April, November and June respectively. , Thesis (PHD) -- Faculty of Science and Agriculture, 2009

Seasonal activity patterns were only significant at Upper Mnxe (p < 0.05), with percent of time spent grazing (77 percent), resting (35 percent) and walking (24 percent) being higher in April, November and June respectively. , Thesis (PHD) -- Faculty of Science and Agriculture, 2009

- Description: In the literature reviewed a lack in leadership competencies to deal with globalisation and global trends within the South African organisation context (Fontyn, 2001; Tizard, 2001; Kriek, 2002) was identified which led to questions being raised on the prevalence of these essential global leadership competencies within South African transnational and global organisations. Realising the need for the development of an outwardly focused and globally competitive leadership model this study sought to investigate: The key generic leadership competencies relevant to globalisation The specific relevant leadership competencies and their prevalence within the industrial development zones Whether or not the surveyed individual competencies were significant and had an impact on global leadership competencies that rendered leaders capable of operating in a global environment. A multi-method research plan was followed in order to consolidate existing knowledge on global leadership competencies and then to expand upon that knowledge. The approach was preferred due to the lack of leadership competency research within Industrial Development Zones. The study consisted of a qualitative study leading to the assessment of the current state of knowledge and understanding of the global leadership competencies. This phase was aimed at stimulating a debate on the topic in preparation for the quantitative phase which investigated the prevalence of these global leadership competencies within the Industrial Development Zones. Through the literature review, fifteen global leadership competencies were identified and these formed the basis for the questionnaire used for data collection. This list of global leadership competencies should, however, not be seen as an exhaustive list as opinions varied on leadership competencies relevant to globalisation (Msomi, 2001; Rossouw & Bews, 2002). iv In the findings of this study: The respondents largely confirmed the prevalence of the global leadership competencies in the Industrial Development Zones. While there existed high internal consistency of the variables measured, the demonstration of the competencies by leaders in the Industrial Development Zones, as perceived by the respondents, was found to be largely insignificant and as such had no impact on global leadership competencies and the ability of the zones‟ leaders to operate in a global environment. The recommendations that ensue should, in view of the limitations cited, be implemented with caution as their generalisability might be limited. , Thesis (PhD) -- Faculty of Management and Commerce, 2009

- Description: This thesis is a multi-level analysis that seeks to examine the utility of applying the concept of social capital in dealing with a complexity of challenges and problems caused by HIV/AIDS in areas of social marginality. It examines social capital in the context of rurality and how its usage can successfully mediate on the effects of all structural factors fuelling the HIV/AIDS epidemic including poverty and social marginality. It does this against the background of scholarly research findings on the relevance of community or neighbourhood social structure in resolving a host of issues affecting its citizens. The study establishes that the ‘public benefit’ of social capital lies in resource connectivity, meso-level interactions and reciprocal transactions useful for HIV/AIDS prevention. Social capital is therefore identified in this study as civic engagement, neigbourliness, voluntary association or civic membership and collective action. The central thesis or argument advanced by this study is that community or village level interactions and associations among people and groups can greatly influence community cohesion and action towards HIV/AIDS prevention, avoidance and mitigation. In its pursuit of a deeper enquiry and understanding of the most often misunderstood concept or rather elusive in both the social science and public health lexicon, the thesis identifies the major sources of social capital as voluntary civic membership or associations in community groups, local village or community assemblages, exchanges of HIV/AIDS specific information, public discussions and other social spaces useful in helping community citizens to get an awareness of HIV/AIDS thereby making them adopt an HIV/AIDS protective behaviour. In this thesis, community or village-level social capital is seen as having a significant effect on household and HIV/AIDS. The study establishes that the prevalence of norms of ‘civicness’ and the vibrancy of horizontal ties at the community or village level generates the needed stocks of social capital for poverty reduction and HIV/AIDS mitigation.Building on Habermas’s(1992) theories of the ‘public sphere’ and ‘communicative action’ andthe Freirian(1996) discourse of ‘dialogue and praxis’, the study highlights the need for social for communication and dialogue in order to break the silence around HIV/AIDS in rural societies. Deliberative discussions or community conversations are suggested to build a critical awareness and consciousness on HIV/AIDS within the community or village context. In this study, quantifiable evidence tends to suggest that there is a strong correlation between lack of HIV/AIDS specific knowledge and HIV/ AIDS vulnerability. The study underscores the need forpublic communication on HIV/AIDS through community-level dialogues and conversations.Community dialogues and conversations are suggested to be active forms of interaction generating significant levels of social capital in the form of public knowledge on HIV/AIDS. This form of public knowledge is perceived as generating action oriented towards HIV/AIDS prevention and fostering the adoption of safer behavioural practices. The thesis also highlights the often muted link or correlation between human capital in the form of education and social capital. In several instances, the study has proven that human capital and education in particular helps in the creation of high stocks of social capital that can be applied to counteract both household and village level HIV/AIDS. The research further establishes the need for citizenship education which is more contextual and calls for critical enquiry, reflection and thinking on the part of all citizens or villagers. All in all, the research extends the existing knowledge on collective efficacy, village or neighbourhood advantage, associational or group membership, village governance and HIV/AIDS in the developing economies. It sheds more light on how village-level processes, interactions and exchanges within the ‘public sphere’ can be streamlined to deal with issues of marginality and rural HIV/AIDS. These study findings on social capital contribute to the ongoing debate about social capital, its relevance and applicability, in solving public health issues and challenges in developing societies. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2009

- Description: The degree to which religious identity acts as a protective buffer against sexual risk - taking in late adolescence and young adults was investigated among 100 Black female university students. Allport and Ross’ Religious Orientation Scale was used to examine the relationship among religiosity, sexual activity and condom use. The results indicated that greater intrinsic and extrinsic religiosity were associated with less sexual activity and condom use. Religious identification therefore protected respondents from sexual risk- taking but sexually active students with high levels of intrinsic and extrinsic religiosity were less likely to use condoms. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2009
