- Description: In her poem Our Voice (Chipasula and Chipasula 1995: 166–67) Noémia de Sousa (1926–2002) speaks about “our voice of Africa” as that voice that is liberative; that voice which opens “up new ways” and “lights up remorse … and burns glimmers of hope in the dark souls of desperate people” who cry out for emancipation from “slavery.” That voice which creates new possibilities by awakening a “cyclone of knowledge.” That voice which can persistently and effectively represent the aspirations of “millions of voices that shout, shout and shout!” for freedom and self-actualization.

- Description: Background: Motivation is critical to health worker performance and work quality. In Bihar, India, frontline health workers provide essential health services for the state’s poorest citizens. Yet, there is a shortfall of motivated and skilled providers and a lack of coordination between two cadres of frontline health workers and their supervisors. CARE India developed an approach aimed at improving health workers’ performance by shifting work culture and strengthening teamwork and motivation. The intervention—“Team-Based Goals and Incentives”—supported health workers to work as teams towards collective goals and rewarded success with public recognition and non-financial incentives. Methods: Thirty months after initiating the intervention, 885 health workers and 98 supervisors completed an interviewer-administered questionnaire in 38 intervention and 38 control health sub-centers in one district. The questionnaire included measures of social cohesion, teamwork attitudes, self-efficacy, job satisfaction, teamwork behaviors, equitable service delivery, taking initiative, and supervisory support. We conducted bivariate analyses to examine the impact of the intervention on these psychosocial and behavioral outcomes. Results: Results show statistically significant differences across several measures between intervention and control frontline health workers, including improved teamwork (mean = 8.8 vs. 7.3), empowerment (8.5 vs. 7.4), job satisfaction (7.1 vs. 5.99) and equitable service delivery (6.7 vs. 4.99). While fewer significant differences were found for supervisors, they reported improved teamwork (8.4 vs. 5.3), and frontline health workers reported improved fulfillment of supervisory duties by their supervisors (8.9 vs. 7.6). Both frontline health workers and supervisors found public recognition and enhanced teamwork more motivating than the non-financial incentives. Conclusions: The Team-Based Goals and Incentives model reinforces intrinsic motivation and supports improvements in the teamwork, motivation, and performance of health workers. It offers an approach to practitioners and governments for improving the work environment in a resource-constrained setting and where there are multiple cadres of health workers.

- Description: Commercial media entertainment offerings in South Africa especially mainstream soap operas, are progressively infusing dominant social values and ideas which are alien to South African tribal societies. In most of the commodified television drama series, people who hold tight to traditional beliefs and values are often characterised as traditionalists, while those who have imbibed the western defined dicta and ideology of modernity are seen as progressives. This study therefore, sought to ascertain how South African tribal language, traditional institutions, values, social norms and ancestral beliefs are portrayed through the television drama, Generations: The Legacy and what the viewers think about those constructions and the implication for cultural identity. The mixed methods approach was employed involving the administration of questionnaire to 350 participants selected through random sampling and a content analysis of 20 episodes of Generations: The Legacy. The findings suggest that Generations: The Legacy tends to portray South African tribal culture negatively (p-value > 0.05). More than half of the respondents (52percent) strongly believe such negative portrayals may erode the cultural identity of black South Africans, 68.6% were of the opinion that Generations: The Legacy gives preference to western culture as against South African tribal culture. The findings further showed that the African values and traditions represented in Generations: The Legacy do not significantly reflect the South African tribal tradition and values (p-value > 0.05). In the few occasions that African traditional values are represented Generations: The Legacy, they tend to be portrayed as old fashioned (p-value > 0.05), and inferior and backward (p-value > 0.05). In addition, the findings indicate that Generations: The Legacy is a vehicle for promoting dominant culture. Nearly, 59percent of the respondents stated that watching Generations: The Legacy affect the way they view South African tribal culture, while 59.1percent indicated that watching Generations: The Legacy has somehow affected their perception of their own cultural identity. In all, participants rated the representation of South African tribal culture as poor. The study concludes that while South African tribal culture is increasingly finding expression on mainstream soap opera, tribal South African values and beliefs are often depicted as old-fashioned, and inimical to modernisation, and individual’s freedom.

- Description: Fluvial systems are dynamic systems in which variables in a catchment and river channel affect the morphology of river reaches. South African rivers are increasingly being exposed to stresses from a combination of factors, one of the most prevalent being the impacts of damming rivers which result in varying downstream sediment fluxes and flow regimes. The sediment load combined with flow characteristics for respective river channels provides the physical habitat for aquatic ecosystems. The damming of the Tsitsa River, through the construction of the Ntabelanga Dam, will change the overall downstream geomorphology. This creates an opportunity for research in the preconstruction window. The current condition of the Tsitsa River was monitored by completing a baseline survey of the channel geomorphology with specific reference to the influence of sediment on river habitats and ecosystem health. Five sites were established in variable reaches of the Tsitsa River, with Site 1 located above the proposed Ntabelanga Dam inundation and Sites 2-5 below the proposed dam wall. Each site included a range of features that can be monitored for their response to the dam. Physical variables, water quality and biota were monitored seasonally to note changes in habitat quality. A baseline survey of the present geomorphology and associated instream habitats of the selected reaches was set up by conducting cross-sectional surveys of channel topography, water slope surveys, discharge measurements and visual and quantitative assessments of substrate. Level loggers were installed at each site to collect continuous data on variations in depth and temperature. Monitoring surveys, in terms of fine sediment accumulation, were conducted to characterise dynamic habitat arrangements and macroinvertebrate community composition. A taxa related physical habitat score for the Tsitsa River was created. The relationship between water quality, physical and ecological characteristics of the Tsitsa River will aid further research in the area as well as create a better understanding of the influence of sediment on river habitats and ecosystem health. Monitoring sites can be used to monitor the impact of catchment-wide rehabilitation on river health prior to the dam being built. After dam construction, the top site above the dam inundation can still be used as a point to monitor the impact of catchment rehabilitation on ecosystem health in terms of fine sediment accumulation.

- Description: Governments, internationally and nationally, are becoming aware of the importance of healthy work environments within their health departments, environments that are caring and supportive to health professionals. This awareness is brought about by the mounting evidence that healthy work environments are critical to recruiting and retaining health professionals. On the other hand, unhealthy work environments can contribute to medical errors, ineffective delivery of care, and conflict and stress among health professionals in the clinical setting and faculty shortage that can compromise academic excellence in the academic setting. The professional nurses working in the South African Military Health Service (SAMHS), a branch of the South African National Defence Force (SANDF) could experience the military environment as unhealthy because it is rigid and controlled. The hierarchical rank structure could deprive them of their autonomy as the decision-making powers are directly proportional to the rank. Stressful conditions could be experienced when these professional nurses are taken away from the well equipped hospital environment to the deployment areas away from home. There was, however, no evidence found on the work environment of professional nurses in the SAMHS during literature review. The aim of the study is therefore to explore and describe the experiences of professional nurses working in the SAMHS and their understanding of a healthy work environment and the scope and nature of a best practice guideline, then to integrate the evidence generated to the evidence emanating from the critical appraisal of the existing best practice guidelines from other health settings in order to develop a best practice guideline for a healthy work environment for nurses in the SAMHS. The study adopted a qualitative, exploratory, descriptive and contextual research design. The research study was made up of three phases. In Phase 1, semi-structured interviews were conducted with professional nurses to collect information on their experiences of working in the SAMHS and their understanding of evidence-based best practice guidelines. The interviews were transcribed by an independent transcriptionist and data analyzed using the eight steps of data analysis as suggested by Tesch. Themes were identified and grouped together to form new categories. The process of coding was supported by an independent coder. Lincoln and Guba’s model of Page | vii trustworthiness consisting of credibility, transferability, dependability and confirmability was used to ensure the validity of the study. An integrative literature review was conducted where the existing evidence-based best practice guidelines for healthy work environment for nurses were searched for, appraised, had data extracted and were synthesized in Phase 2. In Phase 3, evidence generated in Phase 1 and Phase 2 was triangulated, forming recommendations that were utilized to develop a best practice draft guideline for a healthy work environment for professional nurses working in the SAMHS. The draft guideline was sent to five expert reviewers for their comments and recommendations. These were considered in the development of the final guideline. The final guideline consists of several recommendations in four themes: the need for effective leadership to create an empowering environment; effective communication amongst members of the health team; a culture that supports team work, and; the need for an environment that promotes professional autonomy. Further recommendations were made to address factors that impact negatively on enhancement of a healthy work environment. The guideline is intended for use by SAMHS’ leadership, at Levels 2, the strategic level, Level 3, the formation level and Level 4, the unit level (hospitals, sickbays and clinics and nursing college) and all professional nurses working in all the military health institutions of the SAMHS, including the military clinics, sickbays and hospitals irrespective of positions. However, the guideline may also be adapted by nursing institutions outside the military such as public and private hospitals and clinics where they find it applicable. Results

- Description: Clinical teaching is a critical component of the education and training of undergraduate nursing students. It determines the level of clinical competence that nursing students achieve during their studies. It should be informed by current best practice evidence available in the nursing care literature (Emanuel, Day, Diegnan & Prys-Muller, 2011:21-22). Clinical teaching is centred around provision of patient care in clinical practice. It takes place through an interaction between the nurse educator and the nursing students. During this process nursing students are moulded so they can demonstrate minimum competency in order to be registered by the regulatory body. Nursing students learn to become competent nurses in the clinical learning environment (Baxter 2006; Nash, 2007 in Franklin, 2013:35). In South Africa nurse educators are required to be fully responsible for clinical teaching through the use of appropriate teaching approaches and learning facilitation techniques (RSA DoH, 2013:91). The overall purpose of the current research study was to explore and describe the current clinical teaching practices of nurse educators; to search, appraise, extract and synthesise literature related to clinical teaching in nursing; and to develop A Best Practice Guideline for Clinical Teaching at a Public College of Nursing in the Eastern Cape Province. This had to be realized in three phases. In Phase One a quantitative, exploratory, descriptive and contextual study was conducted. A structured questionnaire was used to collect data from the nurse educators involved in clinical teaching within the Diploma in Nursing (General, Community, Psychiatric) and Midwifery programme. The data analysed was used as the basis of Phase Two—namely, an integrative literature review of evidence pertaining to the clinical teaching practices of nurse educators doing clinical teaching within the undergraduate programmes. The evidence from Phases One and Two was used to develop a draft Best Practice Guideline. The draft guideline was reviewed by a group of expert reviewers and their suggestions were incorporated in the final guideline. Ethical considerations were maintained throughout the research study. The rigour of the research process was ensured by cognitive testing of the questionnaire, and by critical appraisal of the literature accessed from an integrative literature review. The v authenticity of critical appraisal was ensured by having the critical appraisal done by the researcher and an independent reviewer.

- Description: The quest to ameliorate and enhance the equitable allocation of resources in the Health Industry remains a global challenge, in particular the distribution of funding resources in public sector health facilities. The need to analyse and understand the appropriation of budget and utilisation of funds by hospital facilities is important in the in the Eastern Cape. The focus of the study seeks to explore recommendations that can be employed in the provincial budgeting process of Hospital Facilities, in a bid to optimise efficiency and improve the funding process as part of the provincial readiness activities towards the realisation of the NHI System and funding approach, wherein the NHI Fund will be a public entity that is not in business to make profit (NHI Booklet 2012: 05). This fund will introduce new systems of paying hospitals and professionals for the services they provide, aiming to be fair to them but to put a stop to unreasonable profits (NHI Booklet 2012: 05). The research has employed the use of descriptive quantitative techniques in order to undertake an expenditure review of existing financial data with respect to the Eastern Cape public Hospitals. The study followed a quantitative descriptive research design, the purpose of this study is that, quantitative research deals in numbers, logic, and an objective stance (Babbie: 2010). The Quantitative aspect of the study found that the data provided, allowed the researcher to organise, synthesise, prioritise and assign value to specific key performance indicators that would be used for the appraisal of hospital facilities in relation to the expenditure patterns based which would present a glimpse into how the Eastern Cape department of health utilises funding resources.

- Description: Enterprise Resource Planning (ERP) systems easily diffuse knowledge and allow good business decisions for Information System (IS) technological and organizational advancement. This research is an investigation of how to improve the strategic management and operational efficiency of Enterprise Information Systems (EIS). A Business Process Management (BPM) framework was designed to integrate varying perspectives of organizational activities for wider collaboration and value derivation. The systematic methodology of Business process management (BPM) enables corporates to be more effective and efficient through continual process improvement. Elements used to build the BPM framework explain how to successfully derive value, inclusive of the performance indicators to measure outcomes. The model was tested with questionnaire data collected from corporates operating in the Southern African region and further refined based on Cronbach alpha reliability tests. The findings improve the interpretation of the determinants for the success of BPM and ERP IS from the user’s perspective. The results show that continuous improvement efforts and organisational support have positive influence on performance and validate the importance of quality, service, information, integration and workflow dependencies. Originality/value – This research extends prior work of BPM frameworks to follow up on customer orientation and servitization. Studies have not investigated relationship commitment between IT and operational business units. The relationship and interdependence of organisational functions is essential for Supply Chain value creation. Industrialization and information technology(IT) integration faces new opportunities. The agility of IT is further explored more into efforts of collaboration, structure, and innovation for future changes, emerging technologies and practices envisioned. This research seeks to propose a framework for the future development of smart supply chain, which can provide theory and case for intelligent operational activities with key technologies, such as RFID, Neural Networks, machine learning and artificial intelligence(AI).

- Description: This study set out to explore and describe in the form of a qualitative case study, an iteration of a Fundisa for Change teacher professional development programme, in this case the Teaching Life & Living short course presented to seventeen teachers as part of their Advanced Certificate in Teaching (ACT) Senior Phase Natural Sciences, at the University of Cape Town. The focus of the research was on describing how the development of teacher environmental pedagogical content knowledge (PCK) was supported and constructed in the course. The Consensus Model of Teacher Professional Knowledge and Skill, an outcome of the 2012 PCK Summit, was used to define the concept of PCK and also contributed the concept of amplifiers and filters as processes that mediate the development of teacher PCK. The study drew on Borko’s (2004) model of a professional development system, using the elements of course, teachers, facilitators and context as an analytical framework. Data generated included a teacher contextual profile questionnaire, audio-recordings of group work, course outputs and reflection and evaluation forms. Data analysis had two phases: the first phase concentrated on the development of analytic memos based on particular data sources whereas the second phase worked across data sources to present the evidence relating to each of the professional development system elements. The study found that teachers were supported in the development of their environmental PCK by the collaborative learning opportunities afforded by the course. Emergent PCK was organised according to five components: assessment knowledge; pedagogical knowledge; content knowledge; knowledge of learners; and, curricular knowledge. Emergent teacher learning ranged in specificity from general, to subject-specific, to domain-specific, and lastly to topic-specific knowledge. Teacher beliefs and orientations, prior knowledge and contexts brought into the professional development system were described as amplifiers and filters to teacher learning of PCK. In particular there were several contextual factors that emerged as themes from the data that had potentially filtering effects. Recommendations included that facilitators create an atmosphere conducive to collaborative learning, that evidence of learner conceptual understanding be examined during the course, that teachers be exposed to in-depth examples of canonical PCK and that more modelling of formative assessment strategies are presented.

- Description: This case study research on the effect of leadership on organizational culture, is based on a small luxury tourism organization – Belmond Safaris – based in Maun, Botswana. The study set out to determine critical incidents that occurred during the tenure of the current general manager with the intention of uncovering her leadership behaviour and how it has shaped the culture of the organization. The literature review identified quantitative and qualitative approaches to researching organizational culture, but settles on Schein’s theory of organizational culture (Schein, 1992; 2010) as the approach adopted in this study. Furthermore, it reviews the various roles of strategic leaders and how these affect the culture of the organization. The study follows a qualitative methodology and applies the Critical Incident Technique to explore how, as a leader, the behaviour of the general manager shaped the organization’s culture. Data triangulation is achieved through the use of multiple sources – interviews, analysis of company documents and the examination of minutes of management meetings. Following the fieldwork, the evidence within the findings of the study required a theoretical reorientation and a shift from strategic leadership to a new focus on relational leadership, highlighting the prominence of social exchanges between the general manager and employees, as opposed to economic exchanges. The study concludes by acknowledging the limitations and delimitations of the study, which include time constraints as well as the deliberate exclusion of certain participants (e.g. camp managers) from the study. In its conclusion the study also presents recommendations for future studies. The researcher recommends a broader study within the tourism industry, as well as a larger and more inclusive sample size, in order to obtain better insights into the study of culture and leadership within organizations.

- Description: In South Africa at present, Literacy is a cause for rising concern, with reading and writing competency in primary school being at an all-time low. It is a widespread belief that part of the problem lies with the lack early childhood education. Only 37% of children under the age of five attend an early childhood development centre. Furthermore, South Africa has a shortage of educators, specifically within the domain of early childhood development. With more research being done in the area of literacy, more educators concur that emergent literacy forms the foundation of formal reading and writing later on. This study is a participatory case study, which reflects on the importance of literacy in the early years, showing the belief that pre-formal schooling, specifically emergent literacy, is directly linked to proficiency in reading and writing in formal schooling. This study also highlights how educators in early childhood development can be involved in ongoing reflective interventions through in-service training and communities of practice. This community of practice was developed as a series of focus groups, which met on a weekly basis to discuss and share thoughts, opinions and experiences surrounding emergent literacy in a preschool context. From multiple focus groups, I found that the participants became more confident in sharing their experiences and building upon each other’s ideas and thoughts. The focus groups, not only added to their understanding of emergent literacy, but enthused them and created more of an awareness in their day to day practices.

- Description: This article makes the point that African states with significant strategic resources and democratic governance systems bargain better in economic and development assistance engagements with China and other partners. In democratic African states, non-state actors play critical complementary roles to the state, leading to multi-faceted forms of African agency. For non-democratic states, a significant limiting factor in their agency is the lack of working relationships between the state and non-state actors. Concomitantly, such states find themselves with weak bargaining and negotiating capacities. If African agency is to be assertive, then state and non-state actors should work together when engaging external partners.

- Description: The frequency and magnitude of landslide occurrence in the Kigezi highlands of South Western Uganda has increased, but the key underpinnings of the occurrences are yet to be understood. The overall aim of this study was to characterize the parameters underpinning landslide occurrence in the Kigezi highlands. This information is important for predicting or identifying actual and potential landslide sites. This should inform policy, particularly in terms of developing early warning systems to landslide hazards in these highlands. The present study analysed the area’s topography, soil properties as well as land use and cover changes underpinning the spatialtemporal distribution of landslide occurrence in the region. The present study focussed on selected topographic parameters including slope gradient, profile curvature, Topographic Wetness Index (TWI), Stream Power Index (SPI), and Topographic Position Index (TPI). These factors were parameterized in the field and GIS environment using a 10 m Digital Elevation Model. Sixty five landslide features were surveyed and mapped. Soil properties were characterised in relation to slope position. Onsite soil property analysis was conducted within the landslide scars, auger holes and full profile representative sites. Furthermore, soil infiltration and strength tests, as well as clay mineralogy analyses were also conducted. An analysis of the spatial-temporal land use and cover changes was undertaken using satellite imagery spanning the period between 1985 and 2015. Landslides were noted to concentrate along topographic hollows in the landscape. The occurrence is dominant where slope gradient is between 25˚ and 35˚, profile curvature between 0.1 and 5, TWI between 8 and 18, SPI >10 and TPI between -1 and 1. Landslides are less pronounced on slope zones where slope gradient is <15˚ and >45˚, profile curvature <0, TWI <8 and >18, SPI <10 and TPI >1. Deep soil profiles ranging between 2.5 and 7 meters are a major characteristic of the study area. Soils are characterized by clay pans at a depth ranging between 0.75 and 3 meters within the profiles. The study area is dominated by clay texture, except for the uppermost surface horizons, which are loamy sand. All surface horizons analysed had the percentage of sand, silt and clay ranging from 33 to 55%, 22 to 40% and 10 to 30% respectively. In the deeper horizons, sand was observed to reduce drastically to less than 23%, while clay increased to greater than 50%. The clay content is very high in the deeper horizons exceeding 35%. By implication, such soils with a very high clay content and plasticity index are considered as Vertisols, with a profound influence in the occurrence of landslides. The top soil predominantly contains more quartz, while subsurface horizons have considerable amounts of illite/muscovite as the dominant clay minerals, ranging from 43% to 47 %. The liquid limit, plasticity index, computed weighted plasticity index (PIw), expansiveness (ɛex) and dispersion ranging from 50, 22, 17, 10 and 23 to 66, 44,34,54 and 64, respectively also have strong implications for landslide occurrence. Landslides are not normally experienced during or immediately after extreme rainfall events but occur later in the rainfall season. By implication, this time lag in landslide occurrence and rainfall distribution, is due to the initial infiltration through quartz dominated upper soil layers, before illite/muscovite clays in the lower soil horizons get saturated. Whereas forest cover reduced from 40 % in 1985 to 8% in 2015, cultivated land and settlements increased from 16% and 11% to 52% and 25% respectively during the same period. The distribution of cultivated land decreased in lower slope sections within gradient group < 15˚ by 59%. It however increased in upper sections within gradient cluster 25˚ to 35˚ by over 85% during the study period. There is a shift of cultivated land to the steeper sensitive upper slope elements associated with landslides in the study area. More than 50% of the landslides are occurring on cultivated land, 20% on settlements while less than 15 % and 10% are occurring on grassland and forests with degraded areas respectively. Landslides in Kigezi highlands are triggered by a complex interaction of multiple- factors, including dynamic triggers and ground condition variables. Topographic hollows are convergence zones within the landscape where all the parameters interact to cause landslides. Topographic hollows are therefore potential and actual landslide sites in the study area. Characterized by deep soil horizons with high clay content dominated by illite/muscovite minerals in the sub soils and profile concave forms with moderately steep slopes, topographic hollows are the most vulnerable slope elements to landslide occurrence. The spatial temporal patterns of landslide occurrence in the study area has changed due to increased cultivation of steep middle and upper slopes. Characterized by deep soil horizons with high clay content dominated by illite/muscovite minerals in the sub soils and profile concave forms with moderately steep slopes, topographic hollows are the most vulnerable slope elements to landslide occurrence. The spatial-temporal patterns of landslide occurrence in the study area has changed due to increased cultivation of steep middle and upper slopes. A close spatial and temporal correlation between land use/cover changes and landslide occurrence is discernible. The understanding of these topographical, pedological and land use/cover parameters and their influence on landslide occurrence is important in land management. It is now possible to identify and predict actual and potential landslide zones, and also demarcate safer zones for community activities. The information generated about the area’s topographic, pedological and land cover characteristics should help in vulnerability mitigation and enhance community resilience to landslide hazards in this fragile highland ecosystem. This can be done through designating zones for community activities while avoiding potential landslide zones. It is also recommended that, tree cover restoration be done in the highlands and the farmers encouraged to re-establish terrace farming while avoiding cultivation of sensitive steep middle and upper slope sections.

- Description: In this paper, we analyse how different domains of subjective wellbeing evolve within seven years in three different cohorts born 10 years apart. On average, general life satisfaction – as well as satisfaction with leisure time, social contacts and friends, and family – declines substantially between the ages of 15 and 44, with the most significant decrease taking place at a young age (early 20s). Nevertheless, trajectories among the three cohorts differ markedly, indicating that, ceteris paribus, responses on subjective wellbeing differ greatly between cohorts born just a decade apart. The results further indicate that the two older cohorts assess family life and social contacts more favourably than the youngest cohort.

- Description: While the West African sub-region has progressed in its efforts to achieve sustainable development, more intensive efforts are needed to address its developmental constraints. Among these constraints, the fragmentation of the sub-continent into small and landlocked countries remain one of the structural challenges to be faced. For this reason, strengthening regional co-operation and economic integration is a significant part in the improvement of the region’s economic performance. Monetary integration, which involves the use of a common currency within the area, is part of the process of economic integration. This study reflects upon the difficulties experienced by countries within the Economic Community of West African States (ECOWAS) without a common currency to facilitate economic growth and development. The study adopted a descriptive methodology and embarked on a thorough analysis of recent and relevant secondary sources. This was done in order to determine the expected effects of a common currency in the community, as well as to evaluate the viability of a single currency in the area. The findings indicate that there are potential gains expected from the establishment of a common currency in the relevant community of countries. These gains are contingent upon the meeting of a number of preconditions. These conditions include, inter alia, the need for a multidimensional approach to regionalism, the sustainability of the fiscal policy framework in the region and a greater convergence of the ECOWAS economies.

- Description: The term “trade” is defined in very wide terms in the Income Tax Act and includes a “business” and a “venture”. For a taxpayer to claim certain deductions in arriving at taxable income, the taxpayer must be carrying on a trade. The expression “carrying on a trade” is not defined in the Income Tax Act. Whether or not a taxpayer is carrying on a trade is a matter of fact. Case law has established certain principles and tests to be applied in determining whether a taxpayer is carrying on a trade. The goal of the thesis was to determine to what extent an activity can be considered as carrying on a trade. This research focused on the letting of property, money-lending, or farming operations in relation to carrying on a trade or business or engaging in a venture. The thesis also discussed at what stage a taxpayer ceases to carry on a trade and what the tax consequences are of ceasing to trade. An interpretative research approach was used in the research as it sought to understand and describe. No interviews conducted for this research and the data used for the research are publicly available. It was established that “carrying on a trade”, including a business, requires an active step taken by the taxpayer to trade. It involves regularity of buying and selling or rendering of services. The intention to trade is important but it is a subjective matter and cannot be persuasive in determining whether a taxpayer is carrying on a trade; objective factors are also considered. If the stated intention to trade matches the actions of the taxpayer, the taxpayer will be considered to be carrying on a trade. In determining whether a taxpayer is carrying on a trade each case must be considered with its own merits.

- Description: Coastal ecosystems are more than microhabitats for marine species. Acting as atmospheric carbon filters, species in coastal environments are directly and/or indirectly associated with transferring organic carbon to species at higher trophic levels. However, the progressing change in global climatic conditions has created the need to assess the consequences of the shifting conditions on both direct and indirect interactions of physical and biological parameters at species and/or community levels. From these perturbations, the effects of biotic homogenization on ecosystem functioning and resilience can also be realised. Herein, I discuss the effects of temperature, nutrients, biotic interactions and habitat characteristics on community dynamics within intertidal rock pool systems on the south coast of South Africa using complementary qualitative and quantitative analytical methods. Seasonality had a significant impact on rock pool species with changes in composition and higher richness in winter than summer. The first two axes of the Canonical Correspondence Analysis (CCA) of the plant and animal communities each explained ~20% of the relationship between physico-chemical parameters and biological variables. The CCA highlighted that seasonal shifts in chlorophyll-a, conductivity, salinity, water depth, surface area and substratum type indirectly influenced species composition. For example, pools with heterogenous substratum comprising a mixture of sand and rock exhibited higher species diversity than homogenously bedded pools. Furthermore, a Bayesian analysis of community structure based on stable isotope ratios was used to assess how trophic pathways of carbon and nitrogen elements reflected community composition and richness. Isotopic biplots showed an increase in food web size, food chain length and the trophic positions of fish and some gastropods in winter compared to summer. There was greater dietary overlap among species in larger pools. In addition, while isotopic nearest neighbour distance and species evenness also showed a positive increase with pool size in summer, the same metrics were almost constant across all pool sizes in winter. These changes in food web packing and species evenness suggest seasonal preferences or migration of species in summer from small pools to larger pools with stable physico-chemical parameters. Furthermore, the presence of fish was seen to promote trophic diversity within some pools. The results from laboratory microcosm grazing experiments demonstrated significant direct and indirect effects of temperature and nutrients within plankton communities. Copepod grazing had an indirect positive influence on phytoplankton biomass and size structure while the interactive effects of temperature and nutrients had contrasting effects on both phytoplankton communities and copepod biomass. Shifts in water chemistry and nutrient treatments were also observed in the presence of copepods. Phosphate addition had a recognisable impact on plankton communities. The presented synthesis of the literature mainly highlighted that positive effects at one trophic level do not always positively cascade into the next trophic level which is evidence of complex interactive biotic, habitat and water chemistry effects within these intertidal ecosystems. Thus, to further understand cascading effects or community structure functioning in general, there may be a need to incorporate and understand species functional traits and how they contribute to trophic diversity, community restructuring and functioning in coastal habitats.

- Description: This research dissertation presents the impact of economic size, market size and exchange rate on South Africa’s trade flows with the European Union under the Trade Development and Cooperation Agreement (TDCA). The Big Five EU members are used to represent the EU trading bloc. The research also examines the effects of economic size, market size and ex-change rate on South African trade flows with members of the Southern African Customs Union and of the European Union in what is called the European Union-Southern African Development Community Economic Partnership Agreement (EU-SADC EPA). The research employs comparative analysis aimed at identifying the differences in the effects of market size, economic size and exchange rate on South Africa’s trade flows with these two trading blocs. The study exploits panel data on international trade of South Africa over the period 2000-’16. A gravity model of trade is used to identify the effect of these three variables on South Africa’s trade flows. The empirical analysis relies on a panel data econometrics framework as an estimation technique for the gravity model of trade between South Africa and the Big Five EU members. This shows the outcomes of the effects of economic size, market size and exchange rate on the trade flows of South Africa in the TDCA. The same technique is applied to estimate the effects of economic size, market size and exchange rate to trade flows of South Africa with the Big Five EU members as well as the other SACU members representing the SADC-EU EPA. In the panel data approach, three models are adopted. These are pooled OLS, fixed effects and random effects that can be estimated. The Hausman tests shows that the random effect is appropriate in the TDCA gravity function and the results indicate a positive relationship be-tween South Africa’s economic/market size and South Africa’s trade flows in the TDCA. In the EU-SADC EPA, the Hausman tests indicated that the fixed effect models are appropriate and the results show a positive relationship between economic size and market size with South Africa’s trade flows in the EU-SADC EPA. However, in the TDCA, the random effect model shows that exchange rate and the trading partner’s market size have a negative outcome on South Africa trade flows. The fixed effect model shows a negative relationship between the exchange rate and South Africa’s trade flows in the EU-SADC EPA. The results also show that it is better for South Africa to trade in the EU-SADC EPA than to remain in the TDCA. This is because the outcomes of economic and market size on South Africa’s trade flows are greater in the EU-SADC EPA than in the TDCA. On the other hand the negative effect of the exchange rate on South Africa’s trade flows is less in the EU-SADC EPA than in the TDCA. The research recommends that policy-makers select trading partners based on the sizes of their markets and economies.

- Description: This treatise compared South Africa's VAT rate to the VAT rate trends of other developing counties (such as Brazil and India), as well as international VAT rate developments. Brazil introduced VAT in 1965 and currently has a multi-dimensional VAT rate system consists of five types of VAT, each type of taxing consumers a t different rate depending on the type of product, the municipality or the consumer's turnover. Brazil's average VAT rate is currently 19%. India moved from an origin-based VAT rate system to a GST rate system in 2017. Their GST system levies VAT on a federal level. as well as a state level and on all interstate transactions. India's GST rates varies depending on the luxurious nature of the supply and their average GST rate is currently 15%. South Africa VAT in 1991 and it comprises of a single-rate VAT system where goods and services of vendors are taxed at 14%, unless the specific goods or services fall under the list of exepted or zero-rated items. South Africa's VAT rate remained unchanged since 1993. Per the research it was noted that despite facing similar political, economical and social dilemmas, developing countries such as India and Brazil changed their VAT rates numerous time since its inception, where South Africa only increased their VAT rate once. Brazil and India furthermore have higher average VAT rates than South Africa, despite correlation with the respective poverty levels indicating otherwise.
