- Description: The Langer Heinrich calcrete hosted uranium deposit is situated approximately 90 km to east of the coastal town of Swakopmund in Namibia. It is run by an Australian owned company, Paladin Energy Limited, along with China National Nuclear Corporation (CNNC) who maintain 25% of the shares. Production commenced in 2007 and has been ongoing. Carnotite is the primary and only ore mineral, and the nature of mineralisation within the Langer Heinrich palaeo channel dictates westward-directed continuous open pit mining. Smaller-scale 1micro pits target near-surface, high-grade, lenses toward the east. The high variability in uranium grade over relatively short distances complicates the grade estimation process. This combined with a low uranium price, and a study aimed at optimising of mine production is one of the key drivers for the research presented in this thesis. The efficacy of four resource estimation techniques, commonly used in the mining industry, are investigated by application to variable exploration, infill drilling and grade-control drill pattern spacing. The drill spacing includes regular grids of 50 m x 50 m, 25 m x 25 m and 12,5 m x 12,5 m exploration data. Also included is grade control drill data, drilled on a 4 m x 4 m spacing. The current selective mining unit (SMU) is 4mE x 4mN x 3mRl which is an indication of the minimum dimension whereby the loading equipment can separate ore from waste. The two datasets are processed by four estimation techniques: Inverse Distance Weighting (IDW, squared and cubed), Ordinary Kriging (OK), Multiple Indicator Kriging (MIK) and Conditional Simulation (CS). The two datasets consisted of real-time mining data from pit G1 (micro-pit) in the eastern parts of the mining licence, and pit H1 (continuous larger open pit) in the western area of the palaeo channel. The reconciliation project aims to provide results suitable for devising optimised mining strategies, particularly in future targets where drill spacing can perhaps be improved to provide suitable data with a greater cost saving strategy. Along with the optimal drill spacing or combination thereof, a preferred estimation technique can be suggested and recommended for future operations that involve mining of surficial calcrete-hosted uranium deposits. Results of this study show that 12,5 m x 12,5 m drill spacing provided estimation accuracies similar to that of the narrow 4 m x 4 m grade control spacing (blast hole drilling spacing). The 12,5 m x 12,5m spacing has potential for accurate grade estimations during mining, and could be supplemented by infill downhole radiometric logging on a 4 m x 4 m spacing when 1 Micro pit: Small pits within palaeo channel usually targeted for their near surface high-grade ore necessary. In general, Multiple Indicator Kriging (MIK) provided the most accurate and robust estimations on the wider spaced exploration data and conditional simulation (CS) proved more efficient on the narrow grade control data. These results correspond with current exploration practices for surficial uranium deposits world-wide. Deposit type, therefore complexity and hence SMU sizes play a pivotal role in drill hole planning and estimation accuracies.

- Description: This study was centred on the Agricultural Innovation System in the North West Province, South Africa as a response to climate change. The study developed during a time when Climate-Smart Agriculture emerged in policy and was developed as a strategic agricultural innovation process in response to changes in climate that increased food insecurity. The Agricultural Colleges embedded in the agricultural system realised that they were teaching students without a clear provision for climate change and therefore needed to initiate climate responsive innovations to comply with the Climate-Smart strategy that had been proposed by the provincial authorities. This provided the context for the study to track and support the innovation process of transitioning towards Climate-Smart responsive curriculum and learning practices within the system. A theoretical framework for the study was developed using a Cultural Historical Activity Theory perspective. This allowed the researcher to approach the research process as two case studies of innovation within the Agricultural Innovation System of the North West Province. The study developed as an iterative process of innovation support and tracking. At the early stages of the research process, data were generated through document analysis and a survey completed by the research participants at the preliminary consultative workshop. The contextual data allowed the researcher to begin to develop a clear contextual profile for both case studies. The consultative workshops were held to orientate the research around the central problems and challenges related to curriculum alignment with provincial Climate-Smart Agricultural policies. The methodology thereafter was developed as an iterative process of successive intervention-innovation workshops where the participating staff in each college reviewed their curriculum with the support of a Climate-Smart Innovation Tool. This tool was developed as a mediating resource for participants to undertake intervention work towards curriculum innovation in their context. The historical analysis from the two consultative workshops and the data derived from the initial use of the Climate-Smart Innovation Tool was used to model the activity systems in the respective colleges and the provincial system. This analysis enabled the researcher to scope how the system was currently functioning and how it had changed over time. During the workshops, curriculum innovations were reviewed and a fuller picture of the challenges of system innovation emerged, especially from a curriculum innovation vantage point. This system analysis was used to analyse emergent tensions and contradictions within the system and to build a picture of the complexities of participating staff initiating innovations towards Climate-Smart responsiveness in the colleges and within the Agricultural Innovation System. During the review and tracking of the supported innovation process the Climate-Smart Innovation Tool was developed into online sub-tools where either Departments or individual lecturers could review and track their own Climate-Smart responsiveness. The tool was shown to be a useful tool for surfacing contradictions, and identifying absences, and thus for charting out the start of reflexive learning and change processes needed for introducing climate responsive knowledge into the system. The study reveals that catalysing of curriculum and learning system innovation aligned with wider innovations in the agricultural innovation system requires specific tools, time and the understanding of the importance of micro-level innovation. The innovations within the system revealed the significance of allowing for time and processes that facilitate ‘ascending’ from the abstract concept of Climate-Smart Agriculture into more concrete curriculum processes. The curriculum review tool developed for this study served as an important double stimulation tool, along with activity system mapping, and ongoing refinement and clarification of the object of Climate-Smart Agriculture and associated contradictions and action plans for climate smart responsiveness in the college context. The tools and processes that were developed during this study, assisting in the emergence of micro-level innovation of the curriculum and learning system. The barriers and processes hampering curriculum and learning innovation within the system were identified. The study concludes with the recommendations on how a Climate-Smart innovation process might best be supported with reflexive tools within a curriculum and learning system during a time of institutional flux.

- Description: For more than a century fingerprint evidence has been used as a tool for the forensic identification of offenders, and has generally been accepted without being tested, challenged or scrutinized because the courts were convinced that no prints look alike or are the same. Fingerprint evidence has been used and accepted on the basis that each person’s friction ridges are unique, that the ridges are permanent and can be transferred to a surface. However, the transferability of the uniqueness raises issues that are very significant in relation to the reliability of fingerprint evidence because only a partial impression is typically transferred. Furthermore, the print can be distorted as a result of pressure and this inevitably affects the impression. Nevertheless, in recent and authoritative Reports from the United States and Scotland, criticisms are being raised against fingerprint evidence. These challenges include the fact that to date there has not been a study to validate the reliability of fingerprint individualisation, the fact that there is no specific requirement with regard as to how much constant or uniform detail between latent print and known print suffices to reach a decision of identification and the fact that there are no objective standards coupled with the problem that there is a lack of scientific validity of the method used for comparisons. This study reviews the law relating to fingerprint evidence in the light of the reports produced by the Office of the Inspector General, United States Department of Justice, Reviewing the Mayfield Case (US) in 2006, the National Academy of Sciences (US) Report in 2009, the Fingerprint Inquiry Report by Lord Campbell in Scotland in 2011, the National Institute of Standards and Technology and National Institute of Justice (US) Report in 2012, and the President’s Council of Advisors on Science and Technology Report (US) in 2016, so as to establish lessons for South African lawyers in as far as reliability, weight and admissibility of fingerprint evidence is concerned. Finally, this study concludes that South Africa’s norm of accepting fingerprint evidence as unquestionable is problematic in law and in science and that there is a need for reform regarding the manner in which fingerprint evidence is evaluated by the courts.

- Description: This study examines how the implementation of CAPS Life Skills curriculum training (as a recontextualising process) is engaging teachers in environmental education. The research was centred on training manuals for Life Skills (Official Recontextualisation Field) and their use in CAPS training at district level in two Eastern Cape sites of recontextualisation (Professional Recontextualisation Field). During the training, teachers developed lesson plans that were reviewed and group interviews were conducted on the training process and its outcomes. The manuals, training process, lesson plans and interview transcripts were analysed for evidence of environmental education, notably content, teaching and learning methods and assessment strategies. Bernstein’s (1990) framework of the pedagogic device underpins this study. Here the concept of the relay is key for tracking the "relay” of the content, teaching and learning methods and assessment strategies through the processes of recontextualisation into the lesson plans for the field of production. During the process of de-location and relocation, gaps are created and this study sought to track and probe patterns of omissions that took place during the relay process in two cases of training. The review of the in-service training course process of recontextualisation and its cascading approach exposed challenges of omission as it became clear that at each level of the recontextualisation process, gaps were apparent. The study highlighted how the 3-5 day workshop process reviewed was not a robust model for professional development. It was not effective and changes in the mode of delivery and processes of support that reach into curriculum practice in the context of the school are recommended. The study concludes that there is a need for continuous professional development as teachers need ongoing support especially for a "new” curriculum like CAPS that is content driven.

- Description: The research used a change management approach to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a central hospital. The study was underpinned by two objectives. Firstly, to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a "central" hospital using the Core Elements Framework of change management developed by Antwi and Kale (2014). Secondly, to use the knowledge gained through literature review combined with the experiences of the managers at Nelson Mandela Academic Hospital to inform future healthcare reforms in general and particularly in the restructuring of hospitals. The Core Elements Framework by Antwi and Kale (2014) identifies six fundamental change elements from both emergent and planned change management approaches. The six elements are regarded by theorists from the two different schools of thought i.e. emergent change and planned change as key for successful change. The Core Elements Framework by Antwi and Kale, (2014) demonstrates the strength of not viewing the two approaches to change management as mutually exclusive but as complementing each other when the other is falling short. The study identified the following: ■ The change was prompted by clearly identifiable external factors more than internal factors. ■ There was notable lack of organizational harmony which may have negatively impacted the change process. ■ The Private Public Partnership (PPP) funding model which was aimed at delivering the central hospital collapsed, after a study discovered that it benefited the private sector more than the public sector. ■ There was no proper consultation of major stakeholders for preparation of the change. ■ Resources in all material forms were not made available for the change to take off, this means that there was no organizational capacity to execute the change. The study draws the conclusion that lack of organizational capacity, organizational harmony and a proper consultation process for stakeholders are the main reasons why the restructuring of the Nelson Mandela Academic Hospital is not yielding the desired results. The study recommends that organizations should implement a multidimensional approach for any change initiative to be successful and that organizations must ensure the availability of the necessary resources when embarking on change.

In this environment asset maintenance evolved and became increasingly important in business over the last couple of decades. Traditionally industry favoured a reactive maintenance strategy but over the years changed to proactive maintenance strategy due to the advancement of technology and skills of maintenance personnel. With increasing automation and mechanisation, production processes are becoming highly complex and the cost associated with asset maintenance has increased consistently over the decades. Studies have shown that about 15-70% of production costs can be attributed to asset maintenance and one-third of maintenance costs are wasted due to inefficiencies in planning. Furthermore, the selection of an effective maintenance strategy is a challenge due to maintenance output that is difficult to measure and quantify. This treatise will investigate the application of a risk based strategy on asset maintenance planning and spare part management of a pharmaceutical company and compare it to best practices. The theory of risk analysis was reviewed and risk analysis pertaining to maintenance planning and spare part management in the Pharmaceutical industry explored. Questionnaires were sent to selected engineering and relevant departments in order to analyse the challenges and good practices in the company relating to spare part management and maintenance planning. A risk based model for the pharmaceutical company was developed after the information gathered in the research. The recommendations were made in a practical approach by presenting the solution in the form of a flow chart. This model will enable the Maintenance Managers, Inventory Managers and Maintenance Planners to identify critical equipment, optimise maintenance schedules and plan spare parts purchasing more accurately.

- Description: The Natal Valley is a ~1000 km long, elongated depression in the seafloor, located within the south-west Indian Ocean, between the coastline of south-east Africa and the offshore aseismic Mozambique Ridge. Knowledge of its present-day crustal structure is important to reconstruct the Gondwana supercontinent break-up history and the concurrent opening of the Indian Ocean, which started during the Jurassic, some ~180 – 150 million years ago. Major geological events relating to this supercontinent break-up including continental rifting, magmatism, the emplacement of extensive oceanic flood basalt as submarine plateaus, vertical processes associated with tectonic uplift, flexural subsidence of the margin and relative global sea-level change are recorded within the crust underlying the south-west Indian Ocean. Although these events have been well modelled, fundamental questions remain regarding the nature and tectonic structure of the crust. Today, the Natal Valley region represents a frontier for geophysical exploration. Early attempts at imaging the crust beneath the seafloor within the south-west Indian Ocean made use of now primitive seismic reflection data acquisition and processing techniques available to them at the time (1960’s - 1970’s). Considering the advancements made in marine seismic reflection imaging, these vintage datasets lacked the horizontal and vertical resolution necessary to most accurately account for and describe features of the upper crust underlying the northern Natal Valley. This study is based on the acquisition, processing and preliminary interpretation of a newly acquired, regional seismic reflection profile, Profile Mz5-007, acquired across the northernmost region of the Natal Valley during the PAMELA-Moz5 cruise in 2016. The methods of marine seismic reflection data acquisition, processing and interpretation are described. The seismic reflection data presented in this dissertation provides a regional-scaled appraisal of the upper crust underlying the northern Natal Valley for the first time. The imagery allows a comprehensive description of crustal structures and features from the very northern Natal Valley, close to the Mozambique coastline, southwards into the southern Natal Valley offshore of Durban. The findings presented here support the notion that the crust underlying the northern Natal Valley experienced roughly N-S orientated trans-tensional stresses in relation to the breakup of West Gondwana. At least two major phases of volcanism are imaged within the seismic stratigraphy. The lower-most event underlies the Limpopo Fan in the northernmost regions of the Natal Valley at a depth of 2 seconds TWT and is interpreted as a seismic expression of the upper surface of the Lower – Middle Jurassic Karoo LIP. The progressive disappearance of this horizon towards the south coincides with the emergence of a second, overlying, as yet unreported volcanic horizon, which extends southwards throughout the Natal Valley. On the basis of its regional distribution, spatial relationship with the underlying event boundary and its deformation history, this volcanic horizon is interpreted to represent a series of basaltic lava outpourings during the Lower Cretaceous, initiated in response to trans-tensional crustal deformation associated with the breakup of West Gondwana. In addition to these two major phases of flood basalt outpouring, a number of localized volcanic flows are imaged throughout the stratigraphy, most notably over the Central Terrace. In addition, at least four major unconformities are identified, all of which are well developed within the Limpopo Fan. One of these is interpreted to represent the well-developed Mid-Cretaceous hiatus in sedimentation, providing a relative seismo-stratigraphic constraint to overlying and underlying seismic units. A review of the structural elements of the crust reveals how the northern Natal Valley is partitioned into two sub-basins separated by a prominent basement high, the Central Terrace, imaged across the central portions of Profile Mz5-007. To the north of the Central Terrace, structural deformation appears largely extensional, characterized by a large (~37 km wide) asymmetrical depression directly to the north of the Central Terrace and only minor structural faulting. To the south of the Central Terrace, trans-tensional stresses associated with withdrawal of the Falkland Malvinas Plateau have deformed the upper crust into a series of apparently southwards tilted crustal blocks, producing a series of deep (3.5 s TWT) half graben-like structures, within which syn-rift fill has an apparent dip towards the south. There is evidence to suggest ongoing reactivation of these fault structures. This zone of deformation is shown to bear resemblances to the faulting mapped onshore of the Kwa-Zulu Natal coastline, providing reason to consider the two regions as a continuous zone of deformation associated with the withdrawal of the Falkland-Malvinas Plateau during the breakup of West Gondwana. Furthermore, a number of post-sedimentary intrusive features are imaged, the largest of which is the Naude Ridge; a large pinnacle-like feature which has penetrated the upper crust towards the southern limit of the profile. This feature corresponds to an abrupt change in seafloor depth and upper crustal structure, suggesting that this feature may mark the transition between subsided continental crust interpreted to underlie the northern Natal Valley to the north and oceanic crust known to underlie the southern Natal Valley to the south.

- Description: Small and Medium sized Enterprises (SMEs) are a vital driver to the world economy. They provide more than 60% of overall employment globally and approximately 80% of jobs in developed economies. This segment however remains underserved by banks who have struggled to serve SMEs effectively. Nevertheless banks are still perfectly placed to capture the needs of SME customers and to provide them with greater value adding services that address their needs. However, this must be done in a cost-effective manner to ensure long-term portfolio and banking profitability. SME Banking faces several challenges centred on the high cost to serve and profitability. For the banking sector to overcome these challenges and still meet increasing and changing customer needs, significant investment in digital technology is required. The literature reviewed identified that in order to unlock the revenue potential embedded within the SME segment; banks need ground-breaking solutions to solve their revenue and profitability conundrum. This study mentions that such solutions will need to be focused around placing banks as market enablers, by way of providing SMEs with a growth platform and not just financial transaction services. The study also identified a hybrid service delivery model and a digital ecosystem approach to SME banking as being pivotal to unlocking the revenue potential embedded within the segment. Through a digital ecosystem approach, banks can leverage their intra and inter banking network to assist SMEs to grow their businesses. In the process, this will serve as a way of increasing penetration into this underserved segment. In addition, such an approach to banking necessitates an acceptance of how interconnected business relationships have the capacity to enable business growth and subsequently to address SME banking risk. To also consider that banks in South Africa continue to view SMEs as being too risky and costly to serve. This study attempts to address this perceived riskiness by presenting a service delivery framework, which consists of key factors that would influence the revenue potential of the SME segments of Commercial Banks in South Africa. The empirical part of the research evaluated banking official’s awareness and understanding of key concepts that is likely to influence their views with regards to the revenue potential of the SME market.

- Description: Social media have become the preferred method of communication for individuals, organisations and even governments. These technologies have become ingrained in our everyday lives and have changed the way we communicate, collaborate are informed of recent happenings around the world. Social media websites are reported to be the most popular around the world. In the government sphere, social media is purported as a technology that will revolutionise citizen participation, service delivery and government-citizen interactions. Accordingly, governments around the world are steadily implementing social media in a bid to meet citizens’ demand for immediate and constant access to information, as well as increased opportunities to participate in government. Public participation has become an important focus area for government which could be used to effectively engage citizens and foster citizen trust. The United Nation’s E-government survey reports the presence of 125 countries on social media platforms. Despite the increased use of social media by governments, consensus among researchers is that governments need guidance on how to use social media effectively to achieve the potential benefits proposed by these technologies. Many social media adoptions by governments have been deemed as experimental; no formal action plan was designed, and many government employees are expected to learn social media use on-the-job. The aim of this research was to investigate and propose a social media model for public participation to leverage the opportunities provided by social media and present an effective and structured approach towards public participation. The research was designed as a mixed methods research using a case study based in the Eastern Cape Province of South Africa. The research involved a survey of citizens in the selected municipality based on the Uses and Gratifications Theory, interviews with employees responsible for social media in said municipality and a contents analysis of the existing social media pages of the municipality. The model was developed from the findings of the survey, interviews and existing literature. The implementation of the model was done in the Nelson Mandela Bay Municipality. The municipality appointed a social media champion responsible for obtaining support from top management and politicians within the municipality. Additional staff were added to the social media team and formal social media training was provided to the team. An official social media strategy was drafted and at the time of writing, needed to be approved by top management. The proposed model was operationalised within the Nelson Mandela Bay Municipality. This research makes several contributions to the E-government and social media fields in South Africa. The major contribution is the provision of guidance for South African municipalities to implement and use social media in an effective manner to achieve public participation. The research provided a phased approach to social media implementation that eliminates ad hoc experimentation and ensures the municipality’s social media activities are effective. The development of the model was based on the characteristics of the municipality and its citizens derived from the interviews and survey carried out. There are five phases in the model; Initialisation, Setup, Organisation, Institutionalisation and Maintenance. The model can be thought of as a guideline, and as such municipalities should adapt the implementation of the model to fit their organisational characteristics. The social media model will assist municipalities to determine the resources, tools and tactics to enable them to implement social media effectively, which will result in an improved engagement and participation process with citizens, and thereby foster trust.

- Description: This qualitative case study of a course pairing offered to final-year electrical engineering students at the University of Cape Town in 2015 was undertaken in order to better understand the ways in which participation in undergraduate courses can prepare engineering students for the workplace. The course pairing consisted of New Venture Planning and Professional Communication Studies. While the former aimed to expose students to the knowledge relating to starting a new business, the latter focused on teaching students how to create written and oral texts to support such an endeavour. Using Roy Bhaskar’s critical realism as a theoretical underlabourer, the study develops understandings regarding the generative mechanisms at work during the two courses. In support of this, the study posits an understanding of employability that moves beyond the acquisition of discrete workplace skills. Rather, employability is conceptualised as discursive transformation, with students being deemed “work-ready” when they develop discursive identities as engineers. Data generation took place by means of focus group and individual interviews, ethnographic observation and documentary research. Margaret Archer’s social realist tools – in particular, analytical dualism and the morphogenetic framework were used to trace the students’ transformations over the course pairing. It was argued that those students who developed discursive identities of engineers were those who, in Archer’s terms, emerged as social actors at the end of the course pairing. Two characteristics of the courses were found to enable this transformation: those parts that promoted deepened understanding of what the role of “engineer” entailed and the parts that provided spaces for students to develop their own personal identities. The findings of the study indicated that discursive identities as engineers were more likely to be developed through the group work and spaces for reflection engendered by the courses than as a result of the formal curriculum. The implications of the research are that, while a focus on employability in engineering education is valid and productive, this needs to be supported by opportunities for authentic learning experiences which afford students the opportunity to engage in learning that promotes real-life application of knowledge. , Thesis (PhD)--Rhodes University, Faculty of Education, Education, 2018

- Description: The focus of this research study is on investigating how certain Nigerian youths expression of their agency at consuming popular music as a cultural product could be constrained by certain identified institutions and their gender in Nigeria. Using General Systems Theory (GST) as a theoretical framework, the country is presented as a social system with identified institutions which function within it that guides and constrains the agency of the individuals who live in Nigeria. A review of academic narratives relevant to the research is presented in this dissertation to provide a context for the study. A critical realist epistemology is adopted for this exploratory study, within the qualitative research tradition. A sample of twenty Nigerian youths living at Summerstrand and Humewood, is selected by the researcher using purposive sampling, and semi-structured interviews are conducted with these participants to gather their opinions and experiences regarding the research study. The narratives are analysed using thematic analysis, and the researcher presents an interpretation of these narratives under various topics in the dissertation. The findings from this study shows how some of these Nigerian youths believe their expression of agency at consuming popular music in Nigeria, to be constrained by certain institutions, and their gender in the country which they are part of, although this constraint could sometimes prove to be positive for some individuals. The recommendations from this research study are relevant to improving youth agency at consuming popular music in Nigeria, and advancing sociological inquiry into popular music and youth agency within an African context.

- Description: The aim of this study was to explain and understand problems facing married students at the University of Fort Hare, Alice Campus. The study population was drawn from the University of Fort Hare, Alice campus. The study used simple random sampling and purposive sampling to draw a representative sample of 50 married students (21 males and 29females) from the population of this study. This study used a mixed research approach. Questionnaires were distributed, for quantitative purposes, and interviews were conducted, for qualitative purposes, among the chosen representative sample. Data that was collected with questionnaires was analysed using Statistical Package for Social Sciences (SPSS) and qualitative data was analysed using thematic analyses and was used to substantiate quantitative findings. The findings in this study expanded on how factors such as, lack of time to study, the impact of multiple roles on the well-being of married students, pressure from having multiple roles and lack of support from family contributed to the poor academic performance of married students. This study revealed high levels of stress and poor academic performance as a result of having multiple roles among married students at the University of Fort Hare, Alice campus.

- Description: The purpose of this dissertation is to gather the community perception of females involved in criminal activities at Rosedale in Uitenhage. The main theory used in this study was the Poverty theory. The study was conducted by using the qualitative research design. Interviews were semi structured and conducted using an interview schedule.20 participants both male and female (youth and adults) were interviewed in Rosedale. The thematic data analysis method was used. The findings of this study revealed that the main reasons for female involvement in criminal activities in Rosedale is due to: drug and alcohol abuse there are too many people selling drugs in Rosedale which makes it easily accessible for the youth to purchase and practise use daily. There are too many shebeens and taverns in Rosedale and they allow under aged children to purchase and consume alcohol this causes negative toxic behaviour. Unemployment there are not enough employment opportunities available for the youth in Rosedale. Poverty, some families don’t have the basic needs to survive daily therefore they choose to turn to crime to support themselves and their families. Insufficient recreational activities, the youth do not have anything to do, there is a lack of recreational activities in the community therefore the youth turns to crime. The main challenges facing the youth in Rosedale is that there are a lot of drop outs or they choose not to attend school, unemployment was mentioned again, gangsterism, there are a lot of house breakings and robberies taking place to purchase drugs. All participants are against females being involved in criminal activities in Rosedale they do not agree with it and think that its’ unethical for a female to participate in criminal activities because females are the care givers, nurtures and providers of their families and the society. More police visibility, the death penalty and employment opportunities were highlighted as the main solutions.

A spatio-temporal, landscape perspective on acacia dealbata invasions and broader land-use and cover changes in the Northern Eastern Cape, South Africa

- Description: Biological invasions are a wicked, social-ecological problem, interacting with numerous components within and across a range of spatio-temporal scales, with the potential to disturb broader socio-economic and ecological systems. Acacia dealbata is an invasive shrub in South Africa, widely naturalised across the grassland biome. Although the deployment of a biocontrol agent on A. dealbata is apparently justified considering its highly invasive and ecologically destructive nature, it should proceed with caution due to the integration of the species into the livelihoods of rural communities. This study sought to understand the nature and extent of the A. dealbata invasion in the northern Eastern Cape. Research was conducted in nine villages in rural Matatiele, Mount Fletcher and Maclear, selected for the pervasiveness of A. dealbata around these villages. A time-series of aerial photographs were systematically classified according to designated A. dealbata and land-use/land cover (LULC) categories in ArcGIS to track changes in the extent and rate of spread of A. dealbata, while standard vegetation surveying techniques were used to determine the current abundance and productivity of A. dealbata in selected areas. A high degree of spatial variability characterised the extent, density and biomass of A. dealbata, as well as the annual rate of spread and biomass production. The growth, productivity and spread of A. dealbata were significantly positive, and relatively few biophysical conditions correlated with the invasion. This was indicative of the broad range of invaded and potentially invasible habitats, suggesting that the extent and abundance of A. dealbata will likely continue to increase, barring deliberate intervention. Broader changes in LULC were also apparent, multidirectional and spatio- temporally variable. Despite a net increase in A. dealbata, the invasion was found to be highly dynamic, with various LULC transitioning to A. dealbata, but in turn A. dealbata transitioning to other LULC. Indeed, biological invasions are dynamic, context-specific phenomena, shaped by the heterogeneity of landscapes. Management interventions to limit or control A. dealbata should therefore consider the spatio-temporal dynamics of invaded landscapes, as well as the local-scale abundance, productivity and biophysical conditions of the area, while taking into consideration the livelihood requirements of the local communities.

A strategy to enhance the role of the church as a social service delivery agent in fighting poverty in contemporary South Africa

- Description: The possible role and involvement of the Church in social development has reemerged as an important focus of contemporary academic and religious development discourse in South Africa. There are strong voices arguing for churches and other Faith-Based Organisations to be regarded as strategic in contributing to addressing the challenge of poverty as agents of social development. Yet, as church congregations multiply throughout South Africa, they appear to be less responsive to the challenge of poverty facing South African communities, contrary to the rich history of churches in the past. The need for churches to be involved in sustainable community-driven development initiatives to fight poverty in their local communities cannot be denied nor be met with just rhetoric and scholarly dissertations by theologians and academics. The vicious cycle of poverty in our communities must be eradicated as it represents a social injustice in terms of South Africa‘s Constitution and speaks to deep structural inequalities inherent in our society. Whilst researchers have made several proposals for churches to move from social welfare and relief, there appears to be little research with a clear practical strategy which congregations can implement to enhance their social service delivery role from social relief to sustainable community development. This has left a considerable gap which the current research sought to address. This study thus responds to the call by previous research for churches to implement strategies other than mere relief. Hence, this study contributes to the religious development discourse in South Africa, by developing a strategy to enhance Church-based social service delivery initiatives from social relief efforts which are not sustainable, to community development efforts which are sustainable and which will be consistent with the current social development policy context and contextually relevant to the socio-economic challenges of poverty and its consequences in South Africa. The study was conducted in two phases. During phase one, the main purpose was to gain a deeper understanding of the historical and current involvement of the Church in providing social services which address poverty in communities, to enhance understanding of the factors which influence the provision of social services by churches, as well as to understand participants views of how church-based social service delivery can be improved in order to fight poverty. For phase two, the goal was to develop a strategy to enhance church-based social service delivery from being social relief to being community development oriented. The following objectives guided the research process: To review selected and applicable literature to gain a deeper understanding of the historical and current involvement of the Church in the delivery of social services in order to fight poverty; To explore and describe the perceptions of church leaders and congregation members of the historical and current involvement of the Church in the delivery of social services in order to fight poverty; To explore and describe the factors which influence Church-based social service delivery in fighting poverty; To explore the views of church leaders and congregation members on how church-based social service delivery can be improved in their churches to inform the development of a strategy to enhance church-based social service delivery in fighting poverty. This study employed a qualitative research approach grounded in the interpretivist social science paradigm. The qualitative research approach necessitated an exploratory, descriptive and contextual method of inquiry. A descriptive case study method was also used, with the Methodist Church of Southern Africa selected as the main case of focus. The target population in this research comprised of Christian churches with a historical involvement in social service delivery in pre-apartheid South Africa. Purposeful sampling of 5 churches was undertaken, namely; Roman Catholic Church (RCC), Anglican Church (AC), Dutch Reformed Church (DRC), KwaSizabantu Mission (KSB) and Methodist Church of Southern Africa (MCSA). Data collection was conducted in two phases. Phase one comprised a literature review; Phase two comprised gathering empirical evidence by conducting face to face semi-structured interviews with clergy and from conducting one focus group interview with congregants. The information obtained from participants was transcribed, coded and analysed using content analysis and by a computer-assisted qualitative data analysis software (CAQDAS), namely ATLAS.ti. Findings revealed a marked difference between the historical and current churchbased social service delivery suggestive of decline, accompanied by the lack of empowerment opportunities for current church leaders and congregation members in community development facilitation. Further evidence suggest the lack of cooperation between church leaders and congregation members; as well as the lack of sustainability of interventions owing to an absence of resources and the lack of capacity to create sustainable economic opportunities. Findings also revealed that church congregations are rich with people with various assets - skills, strengths, capabilities, passions, gifts, talents in various fields, which they can share with one another as congregations and communities. The discussion of findings reflected that historically, Church-based social service provision involved holistic intervention mechanisms, empowerment, collaborations and sustainability of interventions suggestive of second generation strategies of community development, while currently, Church-based social service provision involves mostly social relief and social welfare efforts suggestive of first generation strategies. The findings suggest a holistic strategy for ―reawakening the co-operativeness‖ of congregations to facilitate sustainable Church-based social service delivery towards fighting poverty in local communities. The strategy which was then developed and described with its sub-strategies, namely: Establishment of collaborative relationships Creation of empowerment opportunities Facilitation of holistic interventions The goal of the strategy is to guide church leaders and congregation members in facilitating sustainable Church-based social service programmes to fight poverty.

They represent a wide array of activities that make and circulate sounds, words, and images or a combination of these. It applies to artistic, creative, and copyright works that are for sale, license, commercialisation, or display in some marketplace or public arena.” Using the definition in the CARICOM report, this study will identify the critical success factors that have resulted in the global competitiveness and sustainability of individuals, firms and ventures within the music and film subsectors in Jamaica. To anchor the study of the individual firms and ventures, the study first evaluates the historical evolution and recent trends in the development of the music and film subsectors, including their economic contribution and the main challenges and opportunities for their further development and lessons learned.
