  • Description: The focus of the study was on the contribution of the Wool Clip Project to beneficiaries in King Sabata Dalindyebo Local Municipality (KSD LM). KSD LM is predominantly rural and constitutes an integral part of OR Tambo District Municipality which is part of the Eastern Cape Province. The poverty head count in KSD LM was at 14,7% in 2016. The Eastern Cape had the highest percentage of households owning sheep in the country. Approximately 775, 300 sheep were in KSD LM in 2012. This study was located within the local economic development framework. A gap was identified in the yields in terms of national sales of wool which are not commensurate with the portion accounted for in the national flock. The National, Provincial and Local spheres of government intervened resulting in the introduction of the Wool Clip Project as a vehicle to mitigate the challenges encountered with regard to wool production. Through the intervention, it was expected that there should be an improvement in the national sales of wool. The aim of the research was to determine whether the Wool Clip Project has made a contribution to the beneficiaries. This was done through the following objectives: - Determination of whether the project has made a contribution to its intended beneficiaries in terms of its objectives, which are outlined in the Business Plan for the Wool Clip Project (2014). - Determination of whether there has been adequate public participation as dictated by Chapter 4, sections 17 to 22 of the Municipal Systems Act No. 32 of 2000. - Investigation of whether the project has made a meaningful contribution to the relevant communities through the creation of sustainable employment opportunities. v A literature review was done using relevant sources of information and knowledge such as books, journals, policies, research outputs. The aim was to provide a well thought out theoretical framework. The research methodology applied to this study was qualitative, taking into account the nature of the study. Data was collected by conducting semi-structured interviews with ten respondents, who were selected through purposive sampling. The data was then analysed and interpreted using themes and sub-themes. Based on the findings, it was concluding that the project has had a positive effect on the lives of the beneficiaries, even though there is room for improvement. Secondly, it has been established that public participation took place during the introduction of the project as legislated. Thirdly, the project has not contributed to sustainable job creation but there are, however, some benefits that the community has gained from it. Recommendations were made towards improved implementation of the project.

  • Description: The human immunodeficiency virus (HIV) is one of the most common and dreaded diseases of the 21th century. Today, the disease is still spreading with increasing incidence. “Since the beginning of the epidemic, almost 75 million people have been infected with the HIV virus and about 36 million people have died of HIV. Globally, 35.3 million [32.2–38.8 million] people were living with HIV at the end of 2012” (http://www.who.int/gho/hiv/en/). Several studies have been conducted on herbs under a multitude of ethnobotanical grounds. The use of medicinal plants for the management of HIV has become a common practice especially, in the Eastern Cape Province of South Africa (Wilfred Otang Mbeng, 2013 PhD thesis, UFH). At the beginning of this programme, an ethnomedicinal survey of plants used for the management of HIV infection was carried out in targeted areas of the Province and information on the names of plants, the parts and the methods of preparation were collected. The survey revealed that 18 species representing 12 families were found to be commonly used for the management of HIV, as well as other opportunistic diseases such as tuberculosis, diabetes mellitus, sores, high blood pressure, etc. Carpobrotus edulis was selected for this research because it was the most frequently used in the Province. The foliar micro morphological contents of the plant, its phytochemical and antioxidant activity, in vitro antimicrobial activity, inhibitory effect against HIV-1 protease and reverse transcriptase, mechanisms of action and cytotoxicity were investigated. In terms of the foliar micro morphological contents in plants, an electron microscopy scanning (SEM) was completed. Investigation revealed that both glandular tricomes and calcium oxalate crystals (CaOX) were observed. Consequently, it is hypothesized that the bioactive therapeutic compounds secreted by C. edulis may be produced in the glandular trichomes. An investigation of phytochemical content of the plant extracts (C. edulis) was completed using four solvent extracts (hexane, acetone, ethanol and water). Results of the phytochemical analysis showed that proanthocyanidins (86.9 ± 0.005%) where highest in the aqueous extract with phenolics at 55.7 ± 0.404% in acetone extract, tannin at 48.9 ± 0.28% in ethanol extract, while the hexane extract had the highest levels of flavonoids (0.12 ± 0.05%) and flavonols (0.12 ± 0.05%). Antioxidant studies of the various extracts revealed that aqueous and ethanol extracts were found to be the best solvents for antioxidant activity in C. edulis leaves. GC-MS analysis of the essential oil from C. edulis leaves revealed that the essential oil contained at least 28 compounds. These included, in order of abundance: Oxygenated monoterpenes (36.61%); fatty acids esters (19.25%); oxygenated diterpenes (19.24%); monoterpenes (10.6%); sesquiterpenes (3.58%); and diterpenes (1.43%). Similarly, a GC-MS analysis of the crude hexane, acetone and ethanol extracts from C. edulis leaves identified a total of 59 compounds. Of the 59 compounds, 12 major phyto-metabolites that are active against infectious diseases were identified. To comfirm the potential use of C. edulis to treat infectious disease, antifungal activity of the crude essential oil extract and the four solvent extracts were tested against Candida albicans, Candida krusei, Candida glabrata, Candida rugosa and Cryptococcus neoformans strains. The essential oil extract was found to be the most active against all the fungal strains tested and performed better than the four extracts used various solvents used to extract (hexane, acetone, ethanol and water) the C. edulis leaves were tested for antibacterial and anti HIV-1 reverse transcriptase (RT) activity. The results indicated that both gram-positive and gram-negative isolates were inhibited by the extracts (hexane, acetone and ethanol) but antimicrobial activity was observed for the water extract. The lowest minimum inhibitory concentration values were obtained for the ethanol extract, followed by acetone and hexane extracts. No inhibition of HIV-1 reverse transcriptase was observed for any of the leaf extracts, even up to concentrations of 16 mg/ml. The potential inhibitory activities of the various solvent extracts against HIV-1 protease were evaluated at four different concentrations (16, 1.6, 0.16 and 0.016 mg/ml). Results indicated that the water extract showed almost 100% inhibition of HIV-1 protease activity, with an IC50 of 0.86 mg/ml leaf extract. Other solvent extracts (hexane, acetone and ethanol) however, did not show any inhibition activity above that observed for the DMSO control. The metabolic components in the water extract were subjected to LC-MS/MS analysis, which identified at least 91 compounds present in the water extract. Further studies involving the molecular modelling need to be carried out to confirm the inhibitory potential of these compounds. The cytotoxicity of the water extract of C. edulis leaves was also screened using human Chang liver cells at concentrations ranging bewteen 0.005 mg/ml and 1 mg/ml. Results indicated that the water extracts were not toxic. In conclusion the results from this study support the use of water extracts of C. edulis leaves by traditional healers to treat HIV infections and have identified possible mechanisms of action of the water extracts of C. edulis.

  • Description: The topic of social cash transfers is often viewed with scepticism. In the context of fragile states, questions of misuse, inaccessibility of social services, dependency and sustainability are often raised. This study sought to examine the transformative potential of social cash transfers on child wellbeing in fragile contexts through a case study of the social cash transfer pilot scheme in Bomi County of Liberia. The study specifically set out to to assess the relevance of cash transfers in the context of child wellbeing; determine how the wellbeing of child recipients of cash transfers had transformed; and analyse the determinants of the transformative effects of cash transfers on child wellbeing. The study adopted a quasi-experimental, mixed method, and cross-sectional research design. It utilised existing household survey datasets of the mid term and end term evaluations of the Bomi County pilot social cash transfer scheme conducted in Liberia in 2012 and 2015 respectively. A sample size of 224 (about 12percent of the sample frame) was used where Confidence Level was 95percent and P=0.5. This sample size was divided equally between households receiving cash (experimental group) and households with the same characteristics although not receiving cash transfers (control group). For the qualitative method, 66 participants were purposively sampled. A total of 34 participants participated in the indepth interviews, 32 children were sampled for focus group discussions. These were divided into 16 children from the experimental group and 16 children from the control group. Quantitative data sets were analysed in Statistical Package for Social Sciences (SPSS), and qualitative data was analysed through thematic analysis. The findings from the study provide a persuasive case for the transformative potential of social protection in fragile contexts. The study confirms the relevance of social cash transfers in promoting child wellbeing through empowering families to address children‘s physical and dependency-related vulnerabilities and institutional disadvantage. The study also confirms the transformative effects of social cash transfers on child health, food consumption, education, housing conditions, household assets, and child labour. In addition, the results indicate that social cash transfers mitigated gender based institutionalised disadvantage, created safe and protective environments for children and positively impacted on the local economy. However, the study also showed that, to a limited extent, social cash transfers had unintended impacts, particularly increase in child labour, where children were requested to sell in family petty businesses, and instances in which recipients misused the cash. The transformative effects of social cash transfers on child wellbeing were dependent on the size of the transfer, priorities in the use of cash, decision-making dynamics, and fairness of the selection process. The study proffers a Child Sensitive Transformative Social Cash Transfer Model based on the determinants of the impact of social cash transfer. The study ends by highlighting the critical role of social protection in infusing a transformative dimension to social work practice in fragile contexts, with a view to addressing equity, gender equality and child rights through confronting child vulnerabilities and institutionalised disadvantage.

  • Description: Despite the array of polices adopted to address the housing issue in South Africa in the post ’94’ dispensation, South Africa in 2015 remains riddled with the same housing challenges as at 1994 even despite the significant improvements that have been achieved. Subsidised housing projects completed between 1994 and 2004 are characterised by poor design, poor quality, late delivery, poor location, and spatial marginalisation. To address these shortfalls, the Department of Human Settlements adopted the Breaking New Ground (BNG) principles in 2004 and the housing code of 2009 to mitigate shortfalls in the provision of low cost housing and thereby creating sustainable human settlements. It was in such context that this study sought to assess whether the BNG and housing code of 2009 was implemented in the building of the low-cost houses of the Wells Estate Human Settlement in the Nelson Mandela Bay Municipality (NMBM), constructed post-2004. An exploratory study using both the quantitative and qualitative data collection methods was used to conduct the study. A questionnaire with open and closed questions was used to collect data. To complement the use of the questionnaire, transect walks were also undertaken. The findings of the study were that; firstly: The majority of the beneficiaries belonged to the productive age that is between 18 and 60; Wells Estate depicts a pre ‘94 spatial planning given its peripheral location there by affecting cost to work and job searching; The quality of houses complied with the tenets of the BNG and housing code of 2009; Access to services and facilities like police station, community halls, clinics, and schools remained a challenge because their availability is determined by the population size and utilisation rate, and Access to socio economic opportunities was still a challenge. The beneficiaries of Wells Estate even in the case for businesses owned this; these were for subsistence only such as street vending, shoe repairing, and painting. Given the above findings, the study recommends that: There is need to focus on human capital development through skill development to the productive age group which is unemployed. With skills, the unemployed have an opportunity to look for employment thereby improving their livelihoods; The provision of housing alone cannot alleviate the socio-economic challenges affecting the poor, however there is a need for a multi-pronged approach to address other socioeconomic determinants such as access to employment and education, and There is need to for a collaboration approach between the NMBM and other government departments for instance with the Department of Basic Education for scholar transport.

  • Description: This study examines the nature and characteristics of the informal sector within the Makana municipal area in South Africa. The focus is on the socio-economic characteristics of the informal sector operatives; operational characteristics of the microenterprises that we studied, such as longevity, employment generation, growth potential, and linkages of the informal sector with the formal sector of the economy. Extensive studies on the informal sector have been conducted in many parts of the world relative to South Africa. The key finding in most of these researches is that the informal sector is highly heterogeneous. These studies provide us with the parameters for analysing the nature and characteristics of the informal sector in the Makana Municipality. The results of the thesis show that the majority of people in Makana Municipality join the informal sector as a result of such push factors as unemployment, retrenchment and the need to survive. While there is evidence of lucrative activities amongst the surveyed enterprises, most of the informal sector micro-enterprises are concentrated in the lower segment of the sector where earnings are very low. Results from this study reveal that employment generation (beyond owner-operator) is very limited. The co-existence of a small number of remunerative activities alongside a large proportion of relatively unproductive activities is not only a sign of restricted economic potential but, most importantly, it points to the heterogeneous nature of the informal sector. Precisely, the informal sector encompasses activities which are different in terms of asset holdings, earnings, etc. From the study, it is also evident that the informal sector micro-enterprises play a crucial role in distributing goods produced in the formal sector. Evidence indicates that these micro-enterprises are Iinked to the formal sector. The idea of a 'second economy' devoid of linkages with the 'first economy' is of limited heuristic value. Thus, the 'second economy' is an extension of the first.

  • Description: Heterogeneous photocatalysis is a promising approach for environmental remediation from contaminants including microorganisms and organic pollutants. In this work, hematite nanofibers are fabricated and modified with a novel monosubstituted Pc (4) as well as an asymmetrical tetrasubstituted Pc (5) with the aim of creating hybrid photocatalysts. The photocatalytic activities of the unmodified and phthalocyanine modified hematite nanofibers were compared based on their efficiencies in the photoinactivation of S. aureus and photooxidation of methyl orange. For both applications, the hybrid nanofibers were found to be more efficient photocatalysts than the unmodified hematite nanofibers. Comparison of the modified nanofibers (4-Fe2O3 and 5-Fe2O3) showed that they have comparable antibacterial activity while the 5-Fe2O3 nanofibers are the best for the photooxidation of methyl orange. The singlet oxygen generation efficiency, high activity, versatility, regenerability and thus reusability of the fabricated hybrid nanofibers makes them ideal candidates for real life water treatment studies.
