- Description: Basic Antenatal Care (BANC) is a way of training or upgrading the knowledge and skills of all nurses, midwives and doctors involved in antenatal care at the primary health care level so that the minimum care can be provided effectively. This study was conducted to investigate the implementation of the BANC program by midwives in the Mdantsane clinics during February 2009. Methods: A descriptive study design was undertaken targeting midwives providing antenatal care to pregnant women, in 14 clinics of Mdantsane. Data was collected from 25 midwives in the clinics, and from 140 ANC cards of women attending ANC on the day of their visit to the clinic. Results: The majority of midwives providing BANC in Mdantsane clinics were not trained in BANC. There were 10 trained midwives and 15 not yet trained. A total of twenty five midwives were involved in the study. The number of visits according to the BANC schedule was well known by the midwives in the study. The content of the visits was well known for the first visit, but for subsequent visits, the participating midwives could not state exactly what they do on these visits. They perceived BANC as something beneficial for both midwives and pregnant women with 24 of the participating midwives rating BANC as advantageous. In completing an ANC card, the midwives scored between 48 percent and 100 percent. Under examination, they scored between 52 percent and 100 percent. Lastly on interpretation and decision making, they scored between 0 percent and 92 percent. This could have troubling consequences for the health status of the mother and baby. Weaknesses in providing antenatal care identified in the study included participating midwives failing to fill in the last normal menstrual period (LNMP) and the estimated date of delivery (EDD), which was a worrying observation. Plotting of the gestational age at first visit was also not carried out well as only 47 percent of the midwives in the study did this, meaning that there would be a miscalculation of the gestational age thereafter throughout the pregnancies. The body mass index (BMI) was not calculated as the maternal height and weight were not written on the ANC card. This should be completed in order to check the nutritional status of the pregnant woman to help supplement, if malnourished, and educate on diet, if overweight. Only 17 percent of the midwives in the study plotted the foetal presentation. Failure to plot foetal presentation could lead to complications during delivery because women with abnormal presentations could end up delivering in a clinic instead of the hospital.Conclusion: This study showed that even though midwives are implementing BANC among pregnant women, it is not being carried out correctly. Therefore the programme will not be as beneficial as it would be if put into practice correctly. This is highlighted by the lack of knowledge from the untrained midwives regarding the content of care on subsequent visits. Thus there is an urgent need for BANC training to be conducted and monitored at various sites.

- Description: Abstract This study presents the characteristics of small-scale gravity waves in the mesosphere region as derived from the imaging riometer data at high altitude (~90 km) over SANAE (72˚S, 3˚W). Wavelet analysis and FFT (Fast Fourier transform) have been applied to extract short period gravity wave parameters for the year 2000. The horizontal wavelength, phase speed and observed period of gravity waves are typically 10-100 km, 5-60 m.s-1 and 3-60 minutes, respectively. The horizontal propagation direction is north-eastward throughout the year. This could probably be due to selective filtering by the zonal wind. Zonal and meridional winds in the region of the MLT (mesosphere and lower thermosphere) have been measured using HF radars at high latitudes in the southern hemisphere. Data from January 2000 to December 2003 have been used with the aim of investigating the characteristics of planetary wave activity at ~90 km. For SANAE and Halley stations, 2-, 5-, 10-, 16- and 20-day planetary waves are dominant in summer and winter. The results show the seasonal variations of the mean winds, which are caused by the internal variability of the quasi stationary planetary waves. Planetary wave coupling processes between UKMO assimilated and mesospheric data have also been investigated. The cross wavelet results show a strong coupling during winter months. The results suggest that planetary waves are generated at lower atmospheric heights and propagate upwards into mesospheric heights. However, not all observed disturbances in mesospheric heights can be explained by the propagation of planetary waves from lower atmospheric heights.

- Description: The study was conducted in Mbozi and Ciko villages in Mbhashe Local Municipality of the Eastern Cape Province of South Africa. Two irrigation projects in the area were studied. Consumers and agricultural commodity traders in Willowvale Town, Dutywa, Butterworth and East London were also interviewed. The major objective of the study is to profile and map cabbage, maize and cattle food value chains broadly, and to understand their nature, constraints and opportunities in smallholder agriculture. A multi-stage random sampling procedure was used in which the first stage involved selecting the local government areas. This was followed by the selection of the district and then the respondents. A total of 168 participants were sampled in the proportion of 82 smallholder farmers, 41 consumers, 26 hawkers and 20 agricultural commodity traders. Focus group discussions and key informant interviews were also used during the data collection process. Value Chain mapping was done using the commodity based approach. All value chains under study indicated that they are short and commodities were transacted in unprocessed form. As cabbages and maize move from the farm to retail outlets, value addition start to take place through transportation to the market and processing in supermarkets. The cattle value chain however does not have a forward linkage beyond the two administrative boundaries of the two communities. Less than 3% of the farmers traded livestock, and this was mostly through private sales to neighbours. The farmers‘ major goal in agricultural production is assumed to be an important aspect in lengthening the value chain. As such, results of a Pearson‘s correlation exercise indicated that there is a significant relationship at 0.05% level between goals of the farmers and the village of origin. Some factors that showed significance (p=0.05) in influencing farmers‘ goals are membership of an irrigation project and household sources of income. An analysis of determinants of technical efficiency at farm level was performed using the stochastic frontier model for cabbage, maize and cattle enterprises. The results showed that rainfall adequacy, input costs, market channels and quantity sold are important determinants of cabbage production efficiency. On the other hand, maize production efficiency is positively determined by market price, area under production and rainfall adequacy. Market related variables are major drivers of the cattle value chain efficiency and these include cattle prices, market satisfaction, market channel and farm labour.

- Description: The objective of the study was to determine the antioxidant activity (AA) and the quality of meat from goats and chickens supplemented with Moringa (Moringa oleifera) leaves. For the first experimental chapter, eighteen 9 months old Xhosa lop-eared, castrated goats with an average body weight of 14 kg were used. There were three supplements namely, Moringa oleifera leaves, sunflower cake and grass hay. There were six goats per supplement. The goats were slaughtered after 60 days of supplementation and the Muscularis longissimus thoracis et lumborum (LTL) of the right side of each goat was used to determine fatty acid composition, total phenolic content (TPC), diphenylpicrylhydrazyl (DPPH) assay, 2, 2 azino-bis (3- ethylbenzothiazoline-6-sulphonic diammonium salt (ABTS) assay and reducing power assay of meat. Glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) and lipid peroxidation (thiobarbituric acid reactive substances, TBARS) were taken as parameters to evaluate in vivo AA of the meat. For the second experiment, twelve male broilers were used in four groups of dietary supplementation. Three broilers were allocated per group. After slaughter, the breast muscle was sampled for total phenols, flavonoids, proanthocyanidins, TPC, ABTS, GSH, CAT, SOD, lipid peroxidation, ultimate pH (pH24), colour (L* (lightness), a* (redness), b* (yellowness)), WB-shear force and cooking loss. In both chapters Moringa leaves exhibited the highest AA. Meat from goats supplement with Moringa exhibited the highest AA. Meat from broilers supplemented with a mixture of Moringa leaves, broiler finisher and crushed maize, had the highest (P < 0.05) pH24 and L* values. Moringa can therefore be used to preserve meat without changing the quality of meat.

- Description: The aim of this study was to assess challenges in Public Appointments and Recruitment Processes in Chris Hani District Municipality: A case study of Human Resource Department in Lukhanji Local Municipality (2008-2010) of the Eastern Cape Province. There has never been a detailed research study conducted in the Chris Hani Human Resource Department, regarding the subject in question. The Constitution of the Republic of South Africa in Section 195(i) directs that Public Administration must be broadly representative of the South African people, with employment and personnel management practices based on ability, objectivity, fairness and the need to redress the imbalances of the past to achieve broad representation. The literature review explored extensively the models used in implementing recruitment and appointment processes globally. From those tested models elsewhere, it was evident that South Africa has a great Constitution and good policies regarding Local Government Human Resource Department recruitment and appointment processes not withstanding some challenges cited in the study. This assessment of challenges in the public appointments and recruitment processes in Chris Hani District Municipality assisted in the establishment of the real facts about effective and fair recruitment and appointment processes in the Local Government Human Resource Management Department to deserving communities. It became clear from the study that providing efficient and fair recruitment and appointments processes to the Local Government Human Resource Department in South Africa requires a broader advocacy agenda encompassing the development of Human Resource systems and the generation of numerous skills and expertise to deliver services to the poor people of our country.

- Description: The 21st century has seen nations becoming more competitive yet ironically more interdependent as their future becomes even more dependent on the knowledge, skills, and resourcefulness of its people, creating new opportunities and difficulties for education, (Power, 2000). The education-work-society interdependency has therefore become more important now than ever. It is also because of this triad-interdependency that tertiary education‟s relevance to industry needs has become a crucial issue in societal development. The ever changing needs of South Africa, the unemployment rate, introduction of new technologies and many other ripple effects of globalization have seen more and more pressure mounting on the South African education system as more and more people try to ensure that the education system answers the crucial challenges of the country today and tomorrow.The discussion below provides a detailed account of the context, in which this discourse on curriculum relevance takes place, highlighting some relevant cornerstones of the Reconstruction and Development Programme, (RDP, 1994). Furthermore, this chapter exposes the key research questions and significance of the study. The subsequent chapter 2 gives an account of what other scholars have said on issues of curriculum relevance, development and the South African Higher Education system. Chapter 3 explains the research methodology as a research process used to investigate the problem in question. In this research study the researcher uses both quantitative and qualitative design (online surveys of three groups, these are the graduates, prospective employers and the lecturers). The analysis is based on quantitative data and further substantiated through qualitative data analysis. The subsequent chapter tabulates and lays out the results according to the surveys. The final chapter discusses the findings and makes future recommendations.

- Description: Education has been identified as a priority area by the South African government, in particular by the African National Congress as the ruling party. To this end, huge amounts of money are being spent on education as a service that has been approved by the legislators. Rules and regulations have been promulgated, and among others, the South African Schools Act, Act No. 84 of 1996, has been enacted. Rich research has also been funded with the sole intention of providing quality education to the people. Education of unacceptably poor quality has, however, been the result, as postulated by Peterson and Hassel (1998:55). The above are attested to by the findings that the political tensions emanating from the conduct of the South African Democratic Teachers’ Union and the Professional Educators’ Union, leading to class disruptions and general instability, erode the ethos of accountability on the part of educators and therefore impact negatively on service delivery. Furthermore, the Limpopo Department of Education is not immune to the challenges ranging from the elements of corrupt activities that often surface, teacher attrition which in the main is caused by lack of discipline. Winkler, Modise and Dawber (1998) indicate that teaching has never been easy, and many teachers are leaving their jobs because of the many problems with children in classrooms. Some of the problems cited are children who do not want to learn and learning that is becoming too difficult for the students because they do not want to listen. This study adopted sequential mixed methods namely, quantitative and qualitative research methods which are viewed as complementary rather than opposing approaches. Information was amassed from the subjects through interviews, observation, documentary survey and observation and the information has since been triangulated to validate the facts. All the methodologies employed proved to be useful in this study. The study sought to test the hypothesis “Good governance is informed by strong accountability and future-oriented organisation, continuously steering it towards its mission and vision, and thereby ensuring that the day-to-day management and administration are always linked with the organisation’s values and goals and thus eventually bringing about effectual and accelerated service delivery” to the South African populace without compromise. After empirically testing the hypothesis, showing mixed reaction informed by the findings of the study, five recommendations were made, based on the conclusions arrived at.

- Description: The aim of this study was to examine the effectiveness of a capacity development programme initiated by the Department of Economic Development and Environmental Affairs (DEDEA) as a mechanism to enhance the performance of the employees in order to improve service delivery to the people of the Eastern Cape. The public service is enjoined by the Constitution to provide services that citizens need, and for this reason it is in need of educated, trained and professional public servants, especially in the technical, professional and managerial categories. The department also recognized the potential of public–private partnerships (PPPs) to improve performance in the areas of transformation and service delivery, and that it required investments aimed at developing and strengthening public management capacity. However, the effectiveness of the PPP as a mechanism for capacity development, remained unknown. The literature reviewed overwhelmingly supported the assertion that human capital development is critical for performance in the public service. The review also highlighted the importance of partnerships, especially the role of the private sector in the area of capacity development, advancing the argument that PPPs should be pursued in order to leverage ideas, resources, and capabilities to achieve public service goals. Various research tools, namely interviews, questionnaires and document analysis were used to conduct the study. Data collected and analysed provided empirical evidence of improved performance of both the individual managers and the department in the functional areas of financial governance and management; programme and project management; as well as ethics and professionalism. It suggested a strong correlation between training, capacity development and service delivery. This research found the DEDEA/National Business Initiative (NBI) PPP initiative, as a capacity development mechanism to enhance the performance of the department‟s employees, effective. On strength of the overwhelming evidence gathered through this research, it strongly recommends that the programme be rolled out to other employees.

- Description: Cocos nucifera belong to the family Aracaceae (palm Family). The English name is coconut and it is used extensively as medicinal remedies against infections such as urinary tract infections, gastro intestinal infections, skin and wound infections. The in vitro antibacterial (including anti-listerial and anti-vibrio) properties as well as the evaluation of the combination potentials of the plant extract with six front-line antibiotics were evaluated in this study using standard procedures. The in vitro anti-listerial properties of the crude aqueous and n-Hexane extract of the husk of Cocos nucifera were carried out against 37 Listeria isolates. Twenty-nine of the test organisms were susceptible to the aqueous extract while thirty were susceptible to the n-Hexane extract both at the screening concentration of 25 mg/ml. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.6 - 5.0 mg/ml. For the aqueous extract, average log reduction in viable cell count ranged between 0.32 Log10 and 4.8 Log10 CFU/ml after 8 hours interaction in 1 × MIC and 2 × MIC. For the n-Hexane extract, the log reduction ranged between 2.4 Log10 and 6.2 Log10 CFU/ml after 8 hours interaction in 1 × MIC and 2 × MIC. The time-kill characteristics of the two extracts suggest that at higher concentration (2 × MIC) and longer duration of interaction (8 hr), more bacteria were killed. In vitro anti-vibrio and antibacterial properties experiment revealed that of all the 45 vibrio and 25 bacteria strains that was tested, 37 were susceptible to the aqueous extract and 38 to the n-Hexane extract, while 17 were susceptible to the aqueous extract and 21 to the n-Hexane extract. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.3 - 5.0 mg/ml. viii The time kill studies revealed that for the aqueous extract, average log reduction in viable cell count in time kill assay ranged between 0.12 Log10 and 4.2 Log10 CFU/ml after 8 hr interaction at 1 × MIC and 2 × MIC. For the n-Hexane extract, the log reduction ranged between 0.56 Log10 and 6.4 Log10 CFU/ml after 8 hr interaction in 1 × MIC and 2 × MIC. In the test for the combination interactions, the checkerboard method revealed synergy of 67% and indifferent of 33%, while the time kill assay detected synergy in 72% and indifferent in 28% of the combinations tested. The synergy detected was not specific to any of the antibiotics or the Gram reaction of the bacteria, and no antagonism was detected. We conclude that the aqueous and n-Hexane extract of the husk of C. nucifera contains potential broad spectrum antibiotics resistance modulating compounds that could be relevant in the treatment of infections caused by these pathogens. In addition, the husk which is being discarded as agro waste will opens up a vista of opportunities for utilization for therapeutic purposes

- Description: Abstract Medicinal plants have been for long remedies for human diseases because they contain components of therapeutic value. The growing problem of antibiotic resistance by organisms demands the search for novel compounds from plant based sources. The present study was aimed at evaluating the bioactivity and phytochemical analysis of Hydnora africana on clinical and standard strains of Helicobacter pylori (PE 252C and ATCC 43526), Aeromonas hydrophila ATCC 35654, and Staphylococcus aureus NCT 6571 in an effort to identify potential sources of cheap starting materials for the synthesis of new drugs against these strains. Ethyl acetate, acetone, ethanol, methanol, and water crude extracts of H. africana were screened for activity against the test organisms using the agar well diffusion assay. The Minimum Inhibitory Concentration (MIC50) and Minimum Bactericidal Concentration (MBC) of the most potent extracts were determined by the microdilution method, followed by qualitative phytochemical analysis. Results were analyzed statistically by ANOVA one - way test. Different concentrations (200,100, 50mg/mL) of the methanol, acetone, ethanol and ethyl acetate extracts showed activity against S. aureus and A. hydrophila while for H. pylori, only methanol and ethyl acetate extracts were active; water showed no activity for all studied bacterial pathogens. Mean zone diameter of inhibition which ranged from 0-22mm were observed for all test bacterial pathogens and 14-17mm for ciprofloxacin. The activity of methanol and ethyl acetate extracts were statistically significant (P< 0.05) compared to all the other extracts. MIC50 and MBC ranged from 0.078 – 2.5mg/mL, 0.78-25mg/mL respectively for all tested bacterial pathogens. For ciprofloxacin, the MIC50 and MBC ranged from 0.00976 – 0.078mg/mL and 0.098– 0.78mg/mL respectively. There was no statistically significant difference between extracts (methanol, acetone, ethanol, ethyl acetate) and the control antibiotic (ciprofloxacin) (P> 0.05). Qualitative phytochemical analysis confirmed the presence of alkaloids, saponins, steroids, tannins and flavonoids in the methanol, acetone,ethanol and ethyl acetate extracts. The results demonstrate that H. africana may contain compounds with therapeutic potentials which can be lead molecules for semi-synthesis of new drugs.

- Description: The study investigates the relationship between stock market performance and business cycles in South Africa for the period 2002-2009 using monthly data. This is done by constructing a Vector Error Correction Model (VECM). The study specifies a business cycle model with the business cycle coincident indicator (BC) regressed against, the All Share Price Index (ALSI), Real Effective Exchange Rate (REER), Money Supply (M1), Inflation (CPIX) and the Prime Overdraft Rate (POR). The ALSI represents stock market performance whilst the rest of the variables are to enhance model specification. The study found a positive relationship between stock market performance and business cycles in South Africa. The results also indicated that business cycles are positively related to the lagged variable of the coincident indicator and money supply. In addition, the findings also reveal that BC is negatively related to interest rates and the real effective exchange rate.

- Description: Most soils in the Eastern Cape Province, South Africa are shallow and are low in organic matter. Therefore these soils are structurally fragile and highly susceptible to inherent degradative processes like hardsetting. The objective of this study was to determine the effect of cattle manure, scalping and soil wetness on aggregate stability, penetration resistance and early maize growth in hardsetting soils. Glasshouse and field studies were conducted to determine the effect of cattle manure on aggregate stability and penetration resistance of freshly exposed topsoils by scalping at 0, 10 and 20 cm depths. In the glasshouse cattle manure was applied at 0 and 20 Mg/ha and matric suction was kept at ~ 30 and ~ 400 kPa; contrasting high and low soil wetness. Three soils were put in pots and arranged in a randomized complete block 3 2 2 factorial design. The field study was done at the University of Fort Hare research farm and the treatments were arranged in a split-plot complete randomized design with three replications. Scalping treatment was the main plot whilst the quantity of the cattle manure applied was the sub plot. Cattle manure increased mean weight diameter (MWD) by between 48% and 71% under glasshouse and between 18% and 33% under field conditions, depending on the soil wetting rate. Cattle manure reduced MWD when the soil under field condition was subjected to mechanical shaking. Soil penetration resistance decreased linearly, with increasing soil wetness but it rapidly increased with increase in matric suction up to ~200 kPa and thereafter the rate of increase reduced. In the glasshouse, all treatments had no significant effects on shoot dry weight but low matric suction increased root dry weight by 133%. Interaction of cattle manure and low matric suction reduced shoot length by 6%, shoot fresh weight by 25%, root surface area by 36%, root length by 5% and root fresh weight by 29% compared to the control. In contrast, application of cattle manure and high matric suction increased shoot length by 37%, shoot fresh weight by 136%, root surface area by 159%, root length by 94% and root fresh weight by 119%. In the field, cattle manure application increased root length density and shoot dry matter by 26% and 30% respectively. Cattle manure improved the stability of aggregates of the hardsetting soil under rapid or slow water intake conditions experienced during rainfall or irrigation. However, under field conditions cattle manure acted as a deflocculant and decreased the stability of aggregates when mechanical stress was applied. The effectiveness of cattle manure in improving maize growth in hardsetting soils was determined by matric suction.

- Description: The study focused on investigating challenges and prospects of quality education in rural primary schools in developing countries particularly in Zimbabwe. Reviewed literature indicated that two theories; education as human capital and education as human right advanced increased access to education. Decline of quality of education in the expansion programme portrayed by the decrease of pass rates to below 50 percent, pupils’ low literacy and numeracy prompted investigation. A case study of Ngezi rural primary schools was explored using a sample of 50 respondents selected through stratified random technique. Data were gathered by a combination of qualitative and quantitative methods defined as triangulation. Self- administered questionnaires for heads and teachers, interview guide for grade 7 pupils and SDC and observation guide were the instruments employed for data collection. Analysis of the data was done using descriptive statistics. Findings were that quality of universal education was affected by inadequate supporting inputs and facilities, inappropriate teaching methods and unmotivated teachers. However 80 percent of the schools were staffed with qualified teachers depicting government’s commitment to quality education. 40 % of the schools without qualified leadership were indicative of the effect of poor school conditions to staff turn up. In studies carried out in Kenya, Uganda, Tanzania and India quality also declined as access was increased due to similar causes. Recommendations were to create a strong collaboration among stakeholders through communication to ensure the four conditions for quality are met simultaneously as they are interdependent and reforming the curriculum to suit means and needs of the people.

- Description: Characterization of village chicken phealth and management practices in the Amatola Basin of the Eastern Cape Province, South Africa By Njongenhle M. B. NYONI The majority of rural households in South Africa own village chickens which contribute significantly to their livelihoods. However, limited research has been conducted to characterize, understand and develop village chicken production in South Africa. This hinders the designing and implementation of village chicken-based developmental programmes that will benefit farmers in rural areas. Thus, it is imperative to initiate studies to describe village chicken production. This study was conducted to characterize village chicken production in Amatola Basin of the Eastern Cape Province of South Africa. Baseline information was gathered using a questionnaire survey of 81 identified from 7 out of 13 villages using snowball sampling technique. Consequently, 20 households were selected to participate in a monitoring study (from July 2010 to June 2011) through purposive sampling. Most (60%) chicken flocks were owned by women and mainly raised to meet household food requirements. Some (28.4%) farmers occasionally sold cocks and hens to neighbours, at an average price of R50 (USD7.55) per bird, as a way of culling their flocks and generating income. However, village chickens were mainly kept for food security rather than for their terminal benefit of cash. Although, all chicken flocks were produced under the scavenging feeding system, most (96%) flocks were provided with supplementary feed and drinking water. A majority (93.8%) of households also provided some form of shelter for their chickens. The mean cock to hen to chick ratio was 1:5:15. On average, iii each household owned 17 (±2 S.E.M.) chickens, and hens had 3.3 clutches per annum. Chicks hatched and chickens received as gifts represented the flock entries, while exits included mortality, consumption, sales and gifts or donations, in that order. Generally, both exits and entries were more pronounced in the summer season than in other seasons. Most (81.5%) farmers experienced chicken losses due to predation and health related problems. Parasitism ranked high amongst the village chicken health challenges. During monitoring, the endoprasites identified included nematodes, cestodes and protozoa. Coccidia were the most prevalent endoparasites. The chickens were also infested with a variety of ectoparasites namely: mites, lice, fleas and ticks. The sticktight flea Echidnophaga gallinacean was the most prevalent species. Although ectoparasite infestations were most pronounced in summer, almost all chickens harbored one or more of these parasites throughout the study period. The prevalence and intensity of parasite infestations were significantly (P<0.05) higher in the summer season compared to the other seasons. This was followed by the autumn, spring and winter seasons, respectively. The majority (77.5%) of farmers resorted to alternative remedies, mostly medicinal plants, for treating diseases and controlling parasites. Medicinal plants were used because they were locally available, cheap and perceived to be effective. Therefore, village chicken production in the rural Eastern Cape Province is characterised by several challenges which counter the significant role chickens play in the livelihood of rural households.

- Description: The broad objective of the study was to determine the economic value of local pigs in marketand subsistence-oriented production systems in communal areas of Southern Africa. Data were collected from 288 households to investigate farmer perceptions, effects on pig production and handling of disease outbreaks such as classical swine fever (CSF) in market- and subsistenceoriented production systems. The utilisation of local pigs in these market- and subsistenceoriented production systems in improving people‟s welfare was evaluated. Climate change was identified by farmers in these production systems as a major constraint to pig production hence an experiment was carried out in the hottest season to determine diurnal heat-related physiological and behavioural responses in Large White (LW) and South African local pigs. The same genotypes were used to determine effects of diurnal heat-related stress on their growth performance. Choice experiment was done to determine farmer preferences for local pig traits and implicit prices for these traits in CSF-affected and unaffected areas that were under subsistence- and market-oriented production systems. In this experiment, the importance of heat tolerance was assessed relative to other productive and climate change adaptation traits. Significantly more pigs were culled in the CSF-affected areas that were market-oriented (8.0 ± 1.76) than subsistence-oriented (4.1 ± 1.00) production system. The risk of parasites and disease challenges was high in subsistence-oriented production system and coastal areas. In both production systems, CSF was perceived as destructive since the culling of pigs affected pork availability and income generation. The high risk of disease outbreaks and threat of climate change caused farmers in subsistence-oriented production system to select local pigs for their adaptive traits while those in the market-oriented production system focused on productive imported pigs. Farmers (83 %) indicated that they wanted pig genotypes that were adapted to climate change effects such as hot conditions. Local pigs were found to have superior heat tolerance over LW pigs (P < 0.05) in terms of lower heart rate and skin surface temperature. Frequency per day and duration for behavioural heat loss activities such as wallowing, sleeping in a prostrate posture and sprawling in slurry were also lower (P < 0.05) for local than LW pigs. The superiority of heat tolerance of local over LW pigs was further confirmed by their uncompromised growth performance under high diurnal temperatures. The Pearson‟s product moment correlation coefficient between temperature and feed conversion ratio for LW pigs was strongly positive (r = 0.50; P < 0.001) unlike the weak and positive correlation for local pigs (r = 0.20; P < 0.05). There was a quadratic relationship between temperature and average daily gain (ADG) for both pig genotypes. The regression coefficients for ADG were higher (P < 0.001) for LW than local pigs. It was concluded that at high ambient temperatures, performance of local pigs was less compromised than for LW pigs. Although local pigs were found to be heat tolerant, results of choice experiment showed that this trait was not selected for relative to other traits. Keeping pigs that required bought-in feeds, fell sick often and produced low pork quality (eating quality based on farmer perceptions) negatively affected farmers‟ livelihoods more in subsistence- than market-oriented production system. Farmers in market-oriented production system derived more benefit from productive traits such as heavier slaughter weights and large litter size than subsistence-oriented farmers. Under the subsistence-oriented production system, farmers in CSF-affected areas placed high prices on adaptive traits than the unaffected areas. Subsistence-oriented farmers who were affected by CSF wanted a total compensation price of R10 944.00 (USD1563.43) for keeping a pig genotype with unfavourable traits when compared to R4235.00 (USD605.00) for their CSF-unaffected counterparts. Implicit prices for traits could not be determined for market-oriented production system. It was concluded that farmers in CSFaffected areas placed high economic values on pig traits than farmers from the CSF-unaffected areas. The findings suggest that adapted local pigs can be promoted in subsistence-oriented production systems while productive imported pigs and their crosses with local pigs can be kept in market-oriented production systems.

- Description: The chief purpose of this study was to determine the role of the rural communities in the food security initiatives of the government in alleviating food shortages in the Marange communal area of Mutare district in Zimbabwe. The focus was on local community empowerment; ownership of food security initiatives by the communities; communities‟ independent analysis of needs and priorities; their involvement in designing food security programmes and the role of the government in linking with the communities. The data was gathered using a case study research design with the qualitative method being the main research approach. The primary data was obtained from focus group discussions held in three wards of Marange area and some in-depth interviews conducted with selected key informants. The findings indicate that the government designs food security strategies without considering the input of communities. The communities are introduced and expected to adopt these pre-conceived food security plans at the implementation stage. The results also show that poor community participation in the food security initiatives of the government, specifically during the initial stages, is a significant contributing factor to the continual shortages of food in the communal lands of Marange. It is the view of this study that unless community input in decision making at the planning and designing phases is given preference in the food security interventions of the government in rural Zimbabwe, food security will seldom be achieved. While the government has a significant role to play in food security measures, such interventions can make an important contribution if the use and development of community participation is made central to food shortage alleviation strategies. The principal conclusion of this study is that if food security is an intended ultimate goal in rural Zimbabwe, the communities must participate fully in the conceptualisation, planning, implementation, monitoring and evaluation of the government-initiated food security programmes.

- Description: The research study acknowledges that life is possibly full of conflict, be it psychological, spiritual or otherwise. Conflict is an inescapable reality that confronts Churches and societies regardless of how loving and caring the people are. Conflict brings both the negative and positive impact on the life of Church and society. Conflict presents us with challenges and choices that reflect and shape our personal identity. Technically the challenge is not to avoid conflict, but rather to deal with it constructively. Conflict could be dangerous and destructive. Conflict could also be an opportunity for self-examination, for growth, service to people and giving glory to God. Hence the serious need for developing a theological approach to conflict resolution within the Church and society. Generally, there are two methods to conflict resolution namely: the Law court and Atonement Models based on human and divine effort to conflict respectively. Using mere psychological and legal experience, the Law court models deal with immediate substantive offenses, injustices and inequity faced by people. The Law court methods are sometimes unproductive, unprofitable and short-lived, while the Atonement methods radically deal with deep rooted matters and sinful motivations of the human heart such as idolatry, lusts and cravings. The Atonement models are reliable, fruitful and long-lasting. The purpose of conflict resolution must be to uproot the negative elements and destructive results of conflict, while at the same time preserving it’s beneficial, life- giving qualities to achieve genuine reconciliation. Therefore this new theology of conflict resolution calls for radical change. Change of the heart and on how to deal with conflict in order to accelerate transformation, growth, maturity and peace. Chapter one will provide a general background to the research study. Chapter two before looking at the case of disputes between the Livingstonia and Nkhoma Synods, it will firstly, cite briefly some conflicts in the history of the Church to get an appreciation of the impact of conflict in the life of the Church. Secondly, the chapter will outline the historical background of the Church of Central Presbyterian (CCAP) Blantyre and Livingstonia Synods, Nkhoma Synod and the General Assembly and how the boundary disputes between the two rival Synods started in Malawi. Chapter three will discuss the question of sin and its effects. Humanity cherishes sin in the heart (Ps 51:3-10, 66:19). Milne (1982:107) asserts that sin causes racial prejudice and antagonisms. The problem of sin is the world’s biggest problem. The study will also define conflict and its root causes using Marxist’s conflict conception. The argument of the study will base on the fact that sin brings conflict and produces great divisions among human beings. Therefore, if sin brings conflict with God, His will and between humans, God has provided a divine means to deal with the problem. Chapter four will discuss the answer to question of sin and conflict. There are two dimensions to conflict resolution namely: the Law court and Atonement Models based on human and divine efforts respectively. Contemporary Christian conflict theories are deficient in the God ward dimensions of conflict and most theories and practices come from within the human legal or political professions. Deep rooted matters and motivations of the human heart such as idolatry, anger, revenge, lusts and cravings in opposition to God are better addressed by the Gospel of Jesus Christ. The study will review and critique contemporary models of conflict resolution including the atonement with a view to understand the antithesis of conflict. The study will lastly formulate a synthetic model from various aspects of atonement to bring about a better understanding of conflict resolution. Chapter five will discuss the general application of the full concept of atonement. The question for discussion will be: how can the life, sufferings and death, resurrection and ascension of Jesus Christ that occurred almost 2000 years ago affect us today? How can the atonement conception be applied to resolve human conflict? The atonement of Christ will be ineffective unless it is applied to the lives of human beings. The actualization of the atonement could be done through power of the Holy Spirit who unites a person with Jesus Christ and in their close relationship, the penalty for the person’s sin is paid both together, so by Christ (Stott 1986:256ff). As we relate to God in through confession, repentance of sin and sanctification, we relate to each other that removes the cause of conflict between persons. Chapter six will discuss the application of atonement and reconciliation aspects to specific disputes in Malawi. It will also suggest recommendations on how to deal with those disputes. Christianity is not just a creed, it involves action. What is needed in Christian salvation is the practical restoration of broken relationships between God and creation, the removal of rupture within human race in order to facilitate reconciliation. Reconciliation in Malawian context means restoration, amendment, making up, settling an argument of boundary and bringing back lost relationship between the Livingstonia and Nkhoma Synods. Chapter seven will just deal with summary and conclusion. The theology of conflict resolution calls for change. Change of the heart and on how to deal with conflict. All human efforts in conflict are sometimes unproductive, unprofitable, and short-lived while divine efforts radically deal with deep rooted matters and motivations of the human heart. Divine efforts are fruitful and long-lasting.

What is needed in Christian salvation is the practical restoration of broken relationships between God and creation, the removal of rupture within human race in order to facilitate reconciliation. Reconciliation in Malawian context means restoration, amendment, making up, settling an argument of boundary and bringing back lost relationship between the Livingstonia and Nkhoma Synods. Chapter seven will just deal with summary and conclusion. The theology of conflict resolution calls for change. Change of the heart and on how to deal with conflict. All human efforts in conflict are sometimes unproductive, unprofitable, and short-lived while divine efforts radically deal with deep rooted matters and motivations of the human heart. Divine efforts are fruitful and long-lasting.

- Description: This study examines the nature and character of consensus and contentions around the discourse of community engagement in a South African university context. This is against the background of the growing body of literature that advocates for the need for universities to make their impact felt in communities in more direct ways than through teaching and research. The examination is also against the background of the assumption that the success or failure of community engagement initiatives is, in part, a function of how stakeholders agree/disagree on the meaning and purpose of community engagement. The University of Fort Hare is used as a case study. Interviews and Focus Group Discussions were used for qualitative data collection, whilst a survey was conducted for gathering quantitative data. The study revealed that stakeholders attach different meanings to community engagement, with those possessing power and influence acting as key decision makers. Thus powerful stakeholders (in this case, the university and donor organizations) are at the core of the decision making process, while beneficiaries are pushed to the periphery. Moreover, both the meanings and the activities within which they cohere have important implications for the way beneficiary communities perceive university-community partnerships.
