- Description: Background: Life expectancy in most developing countries has remarkably increased and decreased in mortality, but under 5 years old mortality has increased due to HIV and Tuberculosis incidence. Many factors have been established to influence the mortality rate among HIV patients and understanding the factors contribution to the risk of under 5-year-old mortality is important for designing appropriate health interventions. Excess zeros usually occur in such HIV mortality count data. Mixed models consisting of count part and zero part are often used to describe the observed excess zero in the data. Poisson models are popular modeling inference, but Negative-Binomial models are more flexible in analyzing count data and dealing with overdispersion. Method: This research proposed to develop two-part hurdle models in analyzing areal zero count data. A spatial Bayesian lognormal-logit hurdle model (BLLHM) with random effects characterizes and cross-spatial dependencies were introduced. The parameter inferences and predictions were evaluated using the Markov Chain Monte Carlo algorithm. The model proposed was applied to HIV-positive under 5-year-old mortality collected from the Eastern Cape Department of Health. Results: Bayesian lognormal-logit hurdle model is selected as the best model fit. It is observed that the total number of HIV patients not on ART-HIVnotTB (0.000612, p <0.000) was positively and statistically significantly associated with the HIV-positive mortality of under 5 years patients. Both CD4 counts were done on newly diagnosed HIV rate (CD4count) and HIV-positive new patients screened for TB rate (HIVTBrate) were negatively and statistically significantly associated with the HIV-positive mortality of under 5 years patients (-0.6294, p = 0.000 and -0.00056, p = 0.0052). However, the covariate HIV positive Tuberculosis Preventive therapy (TPT) uptake rate (HIVandTB) was not statistically significantly associated with the HIV-positive mortality of under 5 years patients (-0.00155, p = 0.5392). Conclusion: The model is flexible to deal with zero-inflated and over-dispersed count data. There is a need to consider the risk of cause-specific under-5-year-old mortality in terms of spatial effects. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: The study critically examined the implementation of Public Accountability strategies and mechanisms: A case of Buffalo City Municipality. The problem statement gave emphases on the multiple cases drawn from stats reflected in domestic surveys that shows how corruption and maladministration have impacted the province negatively as well as the extreme poverty lines that dominate the communities in the republic and also the province. The New Public Management Theory was used to interpret the manner in which the participants were expected to give their views on leadership and accountability among others key issues. The objectives of the study were to; To assess the mechanisms implemented by Buffalo City Municipality., To explore the challenges affecting public accountability enforcement mechanisms in Buffalo City Municipality towards eradicating corruption, Determine the manner through which the Buffalo City Municipality can adopt tried and tested mechanism from Regional, national & international case studies on how to effective enforce public accountability for the sustainable management and curbing of corruption for effective and efficient service delivery and to recommend new mechanisms which Buffalo City Municipality can utilise in enforcing public accountability towards eradicating corruption in its institutions in order to encourage sustainable community development through service delivery. The study adopted a case study approach based on a mixed method paradigm where data was collected through a questionnaire, interviews and document analysis. Case studies are normally associated with qualitative research, but can also be used as a method of inquiry employing a positivist epistemology and ontology. A total sample of 50 participants was chosen through a non-probability sampling technique. The major findings of the study reflected that there is a huge break in communication between government and the citizens in the locality while also establishing that the mechanisms currently being used were only as good as the factors influencing their implementation among other issues. Major recommendations included community engagement, capacity building and skills development, retention and expansion, lack of resources, promote individual independence of the community and the enhancement the Public Participation Unit.

- Description: The motivation for this study originated from the problem of children who are victims of rape in the victim support centers. The researcher became aware that most of the children needs more support services for counseling and after care services. The goal of the research was to explore the psychosocial challenges faced by children who are victims of Rape in the victim support Centre. The aim of the study was to determine the psychosocial effects (effects. challenges, support services they receive from professionals) as victims of rape in a victim support center. It was a case study of KwaNobuhle Area, Eastern Cape. The purpose was to identify gaps as there are minimal services rendered to children as rape victims in the victim support Centre. In order to meet the objectives of the study, interviews were conducted to 20 victims of rape (both boys and girls) as well as 6 different professionals working with rape cases from the arrival of the child from the opening until the finalization of the case. Data were analyzed according to the qualitative data - analysis procedures. The researcher utilized the phenomenological research design. The research domain where the interviews took place was at the KwaNobuhle Area under the Department of Social Development jurisdiction. In this study, 20 Xhosa speaking children of different ages, gender, educational standards, and socio-economic backgrounds as well as those who suffered different types of rape, as defined by the Sexual Related Matters Act 32 of 2007; they were all interviewed through the use of a semi-structured interview schedule. The participants were purposively selected as they were all at the victim support center. It has been found that some services are not provided within and are other professionals lack knowledge on how to work effectively with children as victims of rape To add on, the theoretical framework that was used in this study is the victim empowerment theory. This was used as a way of empowering the children who are victims of rape in the Victim Support Centres. The study found out that children who are victims of rape in the Victim Support Centres face psychosocial challenges for instance emotional, educational and behavioural challenges. Furthermore, the study also found out that there are few pschologists in the Victim Support Centres. Therefore, the study recommend that more psychologists should be employed at the Department of health and be placed in Victim Support Centres. More, so, there should be constant supervision and guidance on the care givers within the institution on how to effectively deal with the children who are victims of rape in VSC to avoid psychosocial challenges.

- Description: This thesis presents research findings on current environmental management practices used by the South African National Defence Force (SANDF). Two case studies are presented; the first is the Grahamstown Military Installation (6 South African Infantry Battalion) and the second the South African Army Combat Training Centre (42 Brigade). A combination of three sampling techniques, namely, the stratified, purposive and link-tracing (snowball) samplings were employed and structured questionnaires and semi-structured interviews with key SANDF officials were used as primary data. In addition, secondary data sources in the form of inter alia the first and second editions of the Environmental Management Plan for Defence (2001 & 2008 respectively); the development and implementation of environmental education and training in the military: a joint United States-Republic of South Africa Environmental Working Group Project (2003); Overarching Strategic Statement for 2011; Integrated Environmental Management Information Series: Linking Environmental Impact Assessment and Environmental Management Systems (2004); The Department of Defence Strategic Plan (2010): Republic of South Africa and the South African Defence Review (2012) were studied. In addition, field observations were also carried out within the two military installations training areas between July, 2011 and November, 2013. Primary data on the conditions of training areas, waste removal after training exercises, pollution prevention measures, and rehabilitation efforts to restore degraded training ranges were collected. Furthermore, composite surface sediment samples and water samples were collected for analysis. A total of fifty-six surface sediments and thirty water samples were analysed for the concentrations of heavy metals using the ICP-MS. These attitudes and perceptions are predominantly positive. Statistical analysis (ANOVA) did not reveal any significant differences in responses, especially, between military ranks. However, sporadic significant differences were found in five of the statements in the questionnaire from respondents with different service periods. Furthermore, the emphasis placed on environmental protection within defence force activities worldwide has compelled the South African Department of Defence and Military Veterans (DoDMV) to regulate the management of the environment within its properties. Yet, these efforts have faced numerous challenges ranging from financial to human resource deficiencies. It was found that environmental management practices and programmes at different military installations vary significantly. Consequently, six environmental management programmes were identified at South African Army Combat Training Centre, while only one environmental management programme was identified at Grahamstown Military Installation. This programme is a collaborative effort between the SANDF/DoDMV and the Department of Water Affairs and Sanitation to eradicate invasive alien plant species. In the light of the analysis of official documents and interviews with respondents, it was established that the DoDMV does not have a budget for environmental management services and environmental management is yet to be incorporated into formal military training programmes. There is a severe shortage of environmentally qualified and knowledgeable personnel within the SANDF. Subsequently, all these drawbacks lead to the failure of the implementation of the Defence Force’s Environmental Management System (EMS) and inadequate management of the environment at military installations of the SANDF. Consequently, these challenges have severely compromised the commitment of the SANDF to honour its environmental management obligations. Such deficiencies tend to undermine the sustainable utilisation of the national assets entrusted to the Defence Force. Therefore, this thesis argues that environmental management programmes for the SANDF are based on a very weak foundation. This thesis proposes an ideal model for the successful implementation of the EMS and management of the environment at SANDF military installations. The analysis of water and soil samples led to the identification and quantification of heavy mental pollutants. The concentrations of heavy metals in water samples were varying between <0.01 to <0.05mg/l, but generally constant. Thus, no significant or meaningful statistical results were obtained. Pearson’s correlation coefficient was used to analyse the concentrations of heavy metals obtained in the sediment samples.

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

- Description: The study investigates South Africa-based Diaspora movements and their pursuit of democratic consolidation in Zimbabwe. The study is a qualitative one and made use of both primary and secondary sources. Primary sources included in-depth interviews, Facebook and Twitter posts, whilst secondary sources included textbooks and online journals. The study is premised on both the Political Process and Critical Theories. The study acknowledges that CSOs in general are important key players and have been identified as one of the major actors capable of helping in consolidating democracy. Zimbabwean Diaspora movements have been on the rise due to the mass exodus of its citizens to South Africa following economic collapse and civil strife in the country. The study found out that the civil society and political space in Zimbabwe is mired by partisan use of state security forces, repressive legislations, abuse of human rights and politicisation of the judicial system. These notwithstanding, the study reveals ZEF, CiZC and ZRYM have played their part in trying to consolidate democracy in Zimbabwe from their base in South Africa. They have employed various strategies and these include submitting petitions, advocacy and lobbying, partnerships and dialogues and making use of the Social media. Some of the breakthroughs recorded include educating Zimbabweans and disseminating information through social media, raising awareness and contributing to policy formation. The study, however, notes that apart from their achievements, they have also faced challenges like inadequate resources, xenophobia, leadership crises and donor fatigue. Key findings inferred that strategies used did not yield desired outcomes, and challenges faced made consolidating democracy in Zimbabwe a daunting task. The study recommends that partnerships between the Zimbabwean government and Diaspora movements need to be introduced and sustained in a way that catalyses a relationship where discussions can take place for democracy to be consolidated in Zimbabwe without any form of hostility from the government

The study recommends that partnerships between the Zimbabwean government and Diaspora movements need to be introduced and sustained in a way that catalyses a relationship where discussions can take place for democracy to be consolidated in Zimbabwe without any form of hostility from the government

- Description: This study emanated from the struggle for economic empowerment among small-scale farmers in South African. The study advocates for the establishment of a viable environment where agricultural entrepreneurship can thrive. While the South African Nation Development Plan (NDP) proposed to create one million jobs through agricultural sector by 2030, the majority of small-scale farmers in South Africa are struggling to grow beyond the level of subsistence farming, and the youths appear not to be interested in the farming. It is therefore become necessary to conduct this current study that is exploratory in nature; it explored several factors and barriers to agricultural entrepreneurship development, as well as factors that can contribute to the development of prosperous and sustainable agricultural entrepreneurship among small-scale farmers in South African. The study was conducted in two district municipalities of Eastern Cape Province of South Africa – OR Tambo and Chris Hani. Both quantitative and qualitative research methods were used to make findings. Findings from the study shows that economic empowerment can be achieved through agricultural entrepreneurship development by giving adequate attention to specific factors like individuals’ attitude, production skills, access to market and marketing skills, management skills. Empirically, basic components like personal interests, adequate training and background, efficient extension service, famers’ network and communication, specific goal-oriented, understanding market, farmers’ collaboration, and access to sufficient funding are few of the factors that will make the small-scale farmers grow to the level of commercial farming. The study concluded that prerequisite to developing a sustainable agricultural entrepreneurship climate among small-scale farmers in South African is the combination of basic components aforementioned. Suggestions were made for strong collaboration between government and private sectors to provide development assistance for small-scale farmers as they struggles to develop their small-scale farming to sustainable entrepreneurship level. , Thesis (DPhil) -- Faculty of Management and Commerce, 2020

- Description: Emerging organic contaminants (EOCs) have been the focus of global environmental research for over three decades. EOCs have caused widespread concern due to their extensive use. As EOCs were designed to correct, enhance or protect a specific physiological, their target effects in humans and/or farm stocks are relatively well known and documented. However, there is limited knowledge about their unintended effects in the environment. To address the occurrence, distribution and fate of EOCs in the environment, efficient and reliable analytical methods are needed. The relatively low concentration, high polarity, and thermal lability of some EOCs, together with their interaction with complex environmental matrices, make their analysis challenging. Sample preparation followed by GC or HPLC separation and mass spectrometry (MS) detection has become the standard approach for evaluating EOCs in environmental samples. Physicochemical properties of EOCs range from highly water-soluble (hydrophylic) to highly water-insoluble (hydrophobic). Two groups of these EOCs were considered for study in this work. Pharmaceutical and personal care products (PPCPs) were comprehensively studied in five wastewater treatment plants and their receiving watersheds in Amathole districts in Eastern C ape, South Africa. PPCPs have been widely reported in wastewater influents, effluents, receiving rivers and biosolids, but reports of their occurrence in all these matrixes have been limited by the difficulty of analysis. Therefore, a comprehensive validation of methods was carried out on the influents, effluents, sludge and soil from the irrigated golf course where the effluent of one of the study sites was being used for over three decades now for irrigation. In all, thirteen PPCPs from five therapeutic groups were selected for study in this work because of their administering rate and availability of analytical instrument. Good limit of detection (LOD) and limit of quantification (LOQ) were achieved for the method used. The LOD for the aqueous Three different technologies were employed for the treatment of wastewater in the five selected wastewater treatment plants (WWTPs) and study was carried out to evaluate their ability to eliminate the selected compounds from the influents to the effluents using statistical analysis (ANOVA) at p<0.05 on the percentage removal rate across the three plants. The results had shown eight of the compounds having no significant difference among the treatment operations, whereas the remaining five compounds varied significantly among the treatment technologies under investigation. Principal component analysis was performed on the concentration of PPCPs, their removal rate and also on the physicochemical and treatment operation parameters. Hydraulic retention time (HRT) had correlation coefficient, r = 0.90 with the concentration of PPCPs and removal rates. Furthermore, occurrences, seasonal variation, mean concentration distribution pattern of the compounds, and temporal evaluation of the mean concentration of the pharmaceutical compounds in the five WWTPs during one year of sampling were considered. The results revealed that five products which were diclofenac, ibuprofen, paracetamol, triclosan and diethyl toluamide (DDET) were predominant among the PPCPs in all the WWTPs. The removal efficiency was highest in caffeine with 96 percent, and the lowest was obtained with carbamazepine (4 percent). Risk quotient of the concentration of PPCPs in the effluents and receiving waters was determined to assess their chronic toxicity at three trophic levels: fish, algae and matrixes studied ranged from 0.01 μg/L to 0.25 μg/L, and the LOQ from 0.02 μg/L to 0.78 μg/L. In the solid matrixes, LOD varied from 0.01 ng/g to 0.65 ng/g, and the LOQ between 0.08 ng/g and 5.17 ng/g. Better recovery efficiency was obtained with this mixture of solvents, acetone: dichloromethane (1:1), for the recovery of the five therapeutic groups in the solid matrixes using ultrasonication- assisted techniques. The results show percentage recovery values ranging from 68.8 percent to 107.5 percent diaphian. According to the environmental risk assessment results, ibuprofen and triclosan were found to be the most critical compounds due to their high risk quotient values. These findings will, therefore, help in the future evaluation of the efficiency of different treatment technologies in the removal of various PPCPs from the wastewater and their sustainable management in the aquatic resources in Eastern Cape, South Africa. For the lipophilic organochlorine pesticides (OCPs), the limits of detection (LODs) of the tested congeners varied from 0.04 ng/g (α-BHC) to 0.49 ng/g (endosulfan sulfate) and the limits of quantification ranging from 0.22 ng/g (aldrin) to 2.17 ng/g (δ-BHC).

- Description: Globally, countries, institutions, and organizations are investing time, resources, and human capital on finding best solutions to address poverty, inequality and unemployment; and importantly on achieving sustainable development. This study sought to investigate how social enterprises in Buffalo City Metropolitan Municipality (BCMM) contribute to sustainable social development within the municipality and the country at large. The study endeavoured to answer the following research questions: what is the knowledge level among the selected stakeholders on social enterprise in BCMM? What is the scope, application, and sustainability of selected social enterprises in BCMM? What is the contribution of selected social enterprises in social development in BCMM? What are the bottlenecks associated with the application of social entrepreneurship in BCMM? These questions were answered through mixed methods approaches and techniques, where both qualitative and quantitative data was collected and analysed. The data was collected through in-depth interviews (key informant technique) and a min-survey which was administered to users of the social enterprises. Qualitative data was analysed thematically, while quantitative data was statistically analysed with help of SPSS software. The interpretation of the findings was premised on pragmatic and transformative paradigms. The study further used theoretical lenses such as empowerment theory, capability approach and positive theory of social enterprise to support and explain the findings. The main findings showed that: the selected stakeholders conceptualized social enterprises through the African lens of communal living; the social enterprises widely provided their services across a range of sectors and geographical locations; the social enterprises had direct and indirect contribution to socio-economic development in BCMM. This was specifically through provision of employment, training and skill development among others; the future of social enterprises in the country is bright as many sectors presented opportunities for social investment; and social enterprises face financial constraints, lack of skills in the sector, and competition from the mainstream market. The recommendations from this study address government entities, social services providers and practitioners, social enterprises, and researchers on pertinent endeavours to improve the growth and development of social enterprises. The study concludes that social enterprises are: vital vehicles of socio-economic development, more especially for the marginalized segment of the populations; tools for reducing inequality; platforms for innovations, community participation and conduits of empowerment interventions. Thus, social enterprises play dynamic role and presents potential for capable sustainable social development in the local communities and the South African community at large.

- Description: This study examined the implementation of Tourism curriculum in Secondary Schools in Fort Beaufort Education District in the Eastern Cape. The study arose from a concern that despite the Government of the Eastern Cape organizing workshops to facilitate the implementation of Tourism curriculum for secondary school teachers, research has shown that teachers have not improved their classroom practice. It discussed the concept of Tourism curriculum implementation and highlighted problems militating against curriculum implementation at secondary school level. The researcher adopted the mixed method methodology which is embedded in the post-positivist research paradigm. The post-positivist research paradigm explains the way things are and views objectivity as an ideal that can never be achieved, however research should be conducted with greater awareness of subjectivity. By combining qualitative and quantitative methodologies, it assisted the researcher to strike a balance and avoid being subjective on issues of teacher capacity, teaching strategies and assessment, availability and use of resources and support and monitoring. The research methods used in this study include questionnaires, interviews, document analysis and observations. The findings of the study showed that there are limitations in the implementation of Tourism curriculum because of lack of capacity of School management Teams and teachers who are implementing NCS Tourism. Although the teaching strategies and assessment are stipulated in the curriculum document teachers are not using appropriate methods and assessment. Moreover, there are crucial resources and facilities provided by SMTs and the Department of Education to implement Tourism curriculum, inadequate compared to those provided for other subjects. Moreover there are limitations in terms of support (including training) and monitoring systems which are in place to enable the implementation of NCS Tourism. Possible areas for future research were highlighted and recommendations were made, for example the researcher recommends teachers to be trained adequately in order to effectively implement the Tourism curriculum. Teachers should be encouraged to use new learner-centred teaching strategies and resources should be provided in all secondary schools through the combined effort of the government, Fort Beaufort Education district and the School Management Teams (SMTs). Support and monitoring systems should be in place for proper implementation of Tourism curriculum. Tourism industries should contribute through provision of instructional materials and teachers as implementers of the curriculum should be involved in decision-making and curriculum planning. The government should employ enough teachers qualified to teach Tourism. On the other hand subject advisors should be adequately trained to enable them to provide relevant support to teachers in Fort Beaufort secondary schools. All stakeholders should be involved in fostering skills and capacities at local level to develop sustainable Tourism and local development in an integrated way. The study identified a possible an alternative model for the implementation of Tourism curriculum. , Thesis (PhD) -- Faculty of Education, 2012

- Description: Environmental Education (EE) is essential for addressing environmental challenges.The advantages of EE are undeniable; it might be used to address specific environmental concerns and their implications, as well as to modify behaviours that lead to environmental catastrophes.EE strengthens people's resilience to climaterelated hazards. Global environmental issues have heightened interest in educational policy outcomes and their implications for economic growth and social citizenship. It is worth noting that an effective EE policy has a significant influence on the development of learners' environmental literacy. This study assessed the implementation of environmental education school policy in the Buffalo City Metro Education District, South Africa. This study adopted the pragmatism paradigm of Mixed Method Research(MMR). Concurrent triangulation, which is a design that employs a single data collection technique in which quantitative and qualitative data gathering and analysis are carried out independently yet concurrently, was used for this study. The target population of this study involved 60,412 teachers, 1,770,289 learners in 5205 public schools, and 1 Pro-EE civil society organisation in the Eastern Cape province. This was narrowed down to over 268 public and independent schools, teachers, and principals within the enclave of the Buffalo Metropolitan education district. The study adopted stratified purposeful and simple random probability sampling. In this technique, the sampling frame of the study was divided into strata or groups (principals, teachers, learners, and CSOs) and a sample was purposefully selected from each stratum (Migiro & Magangi, 2011). The stratified purposeful random sampling techniques draw data from 10 principals, 175 teachers, 1500 learners, and 1 CSO. Structured questionnaire; Implementation of EE Policy Questionnaire (IEEPQ) whose reliability co-efficient value using Cronbach Alpha was 0.74, semi-structured interview and documents were the instruments used to collect data for this study. The data were analysed using descriptive statistics of percentage, mean, and standard deviation for the quantitative data while the thematic approach of sorting, coding, transcribing, and categorization was used for the qualitative data. The study revealed the following. When asked whether teachers had studied environmental education in tertiary institutions as part of their professional training, the majority of the teachers'respondents, 108, representing 61.7percent, disagreed with this view. On the flip side, a handful of teachers 67, (38.3percent) agreed with the view of having had some sort of EE knowledge during their professional training as teachers. With regards to the view that learners learn environmental issues through other subjects, most of the learner respondents, 1316 representing 87.7percent, agreed with this view. On the contrary, a minority of the respondents 184 (12,3percent) had a dissenting opinion. This indicates that most learners in school learn about environmental concerns through other traditional subjects. The study established that EE content is manifest in teachers' and learners' textbooks, teaching methods, and co-curricular activities. However, the study identified lapses in how teachers and learners integrate EE into their day-to-day practices. Therefore, the implementation of the EE policy seems to be an exercise in futility. The absence of a policy guideline document has made teachers and school administrators incapacitated in the implementation of EE school policy. , Thesis (PhD) -- Faculty of Education, 2022

Half of the goats in each genotype were supplemented with 200g/head/day of sunflower cake. The other half of goats in each genotype was not supplemented. The goats were slaughtered at day 90 to determine slaughter weight (SLW), cold dress mass (CDM), meat colour, cooking loss, meat pH and Warner-Bratzler (WB) shear force values. Furthermore, a consumer sensory evaluation of cooked or fried chevon from supplemented and non-supplemented goats was conducted with consumers of different ages, tribes and gender. The XLE and NGN goats had higher pH24 (P < 0.05) than BOR and XBC goats. Supplemented BOR goats had higher L* values than their non-supplemented counterparts (P < 0.05). The other meat quality attributes in XLE and NGN were comparable to those in meat from the Boer goat. Female respondents gave higher (P < 0.05) sensory scores than male respondents for both cooked and fried meat on aroma intensity. Shona consumers gave higher (P < 0.05) aroma intensity scores than the Xhosa and the Zulu consumers for both cooked and fried meat. In the non-supplemented goats, fried meat for all genotypes was superior (P < 0.05) to the cooked meat for initial impression of juiciness. Age and gender of respondents and thermal iv treatment influenced initial impression of juiciness scores (P < 0.05). The quality of chevon from XLE and NGN was comparable to that of the Boer goat, and dietary supplementation improved most meat quality attributes. Chevon from the supplemented goats had higher consumer sensory scores than chevon from the non-supplemented goats. Keywords: supplementation, meat colour, ultimate pH, consumer sensory evaluation, Xhosa lop eared, Nguni, Boer goats.

- Description: Developing countries are embracing Information Communication Technologies (ICTs) as a tool for alleviating poverty. There are, however, still challenges that developing countries face in trying to establish Information Communication Technology for Development (ICT4D). Among the major challenges is the lack of proper resource management which results in poor sustainability of ICT4D initiatives. If these ICT4D initiatives are to be sustainable for the benefit of current and future generations, proper resource management methods are to be developed and applied. This study proposes a resource management framework that can be applied to the management of ICT4D resources with the aim of achieving sustainability. The framework is informed by theory, and validated through enquiry in the field. Qualitative research methodology was used as a research approach for this study where three rural ICT4D initiatives were used as case studies. The case studies were conducted in rural Zimbabwe to investigate how proper resource management can influence the sustainability of ICT4D initiatives. It was identified from the study that the lack of proper resource management methods adversely affects the initiatives’ sustainability. The proposed resource management framework will guide ICT4D resource management to enhance the initiatives’ sustainability.

Re-appraising entertainment-education praxis and reception in subaltern spaces: the case of Tsha Tsha in South Africa

- Description: The entertainment education (E-E) strategy has gained currency in development communication scholarship and praxis. However, the theoretical treatment of the strategy has mostly emphasised questions of effectiveness thereby paying minimal attention to substantial resistances encountered at the message reception level. This study investigates the praxis and reception of the E-E television drama Tsha Tsha. It uses the Cultural Studies approach and reception theory to explore the consumption of Tsha Tsha by subaltern black South African youths located within specific socio-historical contexts. Audiences’ negotiated readings were used to critique the assumption that E-E messages are ‘unproblematically’ received by target audiences. Tsha Tsha’s E-E strategy and its theoretical and methodological inputs were also appraised with a view to locating the intervention within the trajectory of E-E and development communication interventions. The emerging insights were critical in understanding whether contemporary E-E interventions have transcended modernisation practice. While the focused synthesis approach, consisting of qualitative content analysis, document analysis and literature review, was used to evaluate Tsha Tsha’s use of the E-E strategy, reception analysis comprising of focus group discussions and follow up in-depth interviews with selected subaltern black South African youths was employed to explore viewers’ social production of meaning from the media text. This process enabled the study to identify the locus of meaning between the two contenting poles: the media text and situated readers. The study’s findings indicate that some contemporary E-E interventions have transended ‘modernisation practice’. Their conceptual and methodological approaches have embraced the central tenets of communication for social change. The results from the reception study also clearly indicated that E-E enterventions face resistances in subaltern discursive spaces. Situated readers’ negotiation of Tsha Tsha showed that viewers are not passive readers of E-E texts. Rather they are engaged in an ongoing process of re-interpreting and resisting the ‘preferred text’. Audiences situated discourses and lived experiences at times provided alternative frameworks through which the ‘dominant meanings’ were re-interpreted and even opposed.
