- Description: Literature on generational theory has paid much attention to the differences in values and work ethics between employees from different generational cohorts, but more specifically between managers and the Millennial Generation. These differences in values and ethics affect the way in which multigenerational employees perceive one another, which often leads to conflict and demotivation in the workplace. In an attempt to explore the perceptions of managers of the Emergency Medical Services regarding the management of the Millennial Generation, the researcher undertook a qualitative, descriptive, exploratory and contextual study. Data were gathered through 11 in-depth semi-structured interviews with managers of provincial Emergency Medical Services in the Nelson Mandela Bay Health District. Data were analysed by using Tesch’s steps in data analysis. During the data analysis, the following four main themes emerged: The employees from the Millennial Generation lacked the discipline required for working in emergency services. The employees from the Millennial Generation had up-to-date knowledge, but had little practical experience. Specific attributes of the Millennial Generation were identified. The managers indicated that the employees from the Millennial Generation were in need of management support. The researcher found that many of the participants’ perceptions were inaccurate and influenced by preconceived generational stereotypes and prejudices. The research ended with recommendations, which should assist managers to manage employees from the Millennial Generation in the Emergency Medical Services more effectively. Recommendations were also made for further research. It is acknowledged that the research study had limitations, which included the fact that the data were only collected from one of the eight districts in the Eastern Cape and that the study did not include the private ambulance services in the Nelson Mandela Bay Health District.

- Description: A psychobiography is the construction of an individual’s life according to a psychological theory. This psychobiography reviews the life of Steven Paul Jobs (1955-2011), United States information technology intrepreneur and inventor. This study employs a qualitative, case study design. The researcher preferred a specific individual, therefore this study entails a non- probability, purposive sampling procedure. The data collection consists of primary and secondary sources. Data analysis was conducted according to Alexander’s (1988) model, as well as Miles and Huberman’s (1994) approach. The research conducted was done in an ethical manner. The primary aim of this study is to describe and interpret Jobs’ personal development through the application of tevinson et al.’s human development framework. Jobs was born, and soon after birth, given up for adoption. At the age of twenty-one, he and his friend, Steve Wozniak, invented Apple Computers. Jobs was known as an entrepreneur, innovator and genius, and was recognised as a pioneer in the information technology world. Regardless of personal and business disappointments, he designed successful products, generated enormous profits and led Apple to become the world’s most valuable and leading company. Through exploring Jobs’ life, a holistic overview of his personal development was obtained. The findings revealed that Jobs created a life structure for himself which allowed him to follow his dreams and spiration.

Complex 3 together with the previously reported complexes tetrakis[(benzo[d]thiazol-2-yl phenoxy)phthalocyaninato]zinc(II) (4) and 3-(4-((3,17,23-tris(4-(benzo[d]thiazol-2-yl)phenoxy)phthalocyaninatol)oxy)phenyl)propanoic acid zinc(II) (5), were linked to gold nanotriangles (AuNTs) through S–Au/Au–N self-assembly to afford the conjugates (3-AuNTs, 4-AuNTs and 5-AuNTs). The photophysicochemical behaviour of the complexes and their conjugates were studied. The asymmetric complexes 3 and 5, displayed improved triplet and singlet oxygen quantum yields compared to the symmetric complex 4, while all conjugates displayed improved triplet and singlet oxygen quantum yields compared to their respective complexes alone. The complexes and their conjugates could serve as good candidates for photodynamic therapy.

- Description: Measures of mathematics achievement (documented locally, and in internationally comparative terms) have shown that South African learners whose first language (L1) is different from their language of learning and teaching (LoLT) are at a significant disadvantage, most particularly learners from vulnerable or marginalised communities. This transdisciplinary case study looks at two experienced Grade 4 teachers’ mathematics classroom talk practices. It is situated within a second language (L2) teaching/learning context in which teachers and learners share the same first language, but mathematics learning and teaching takes place officially through an L2 (English). The study is located within a qualitative and interpretive framework. It brings together insights from a range of distinct but complementary theoretical disciplines in its analysis of the empirical classroom observation and interview data. Its theoretical framing derives initially from professional literature relating to L2 teaching and learning. This is then embedded within a broader theoretical frame deriving from the work of Vygotsky, Bernstein and Halliday, each of whom has focussed on the centrality of language to the teaching/ learning process, as well as contributed to a heightened appreciation of socio-cultural influences on learners’ meaning-making processes. The study illuminates some of the linguistic challenges to L2 children’s maximal participation in the learning of school mathematics. It points too to the significant challenge many South African mathematics teachers face in trying to meet curriculum coverage and pacing demands, while simultaneously facilitating their learners’ ongoing induction – in and through L2 predominantly – into mathematically-appropriate discourse. Grade 4 is a year in which such challenges are often more acutely felt. Independently of the transition across to an L2 for the majority of South African learners, this is the year also where - relative to the foundation phase years - learners encounter an expansion of knowledge areas and more specialised academic text. Many learners struggle to adjust to these higher conceptual and linguistic demands, often leading to what has been termed a ‘fourth-grade slump’. The study highlights the need for more sustained and proactive challenging of perceptions that English as LoLT is the obvious route to educational - and subsequent economic - opportunity. Recognition of the consequences deriving from the choice of English as the main LoLT for mathematics teaching and learning could help counterbalance deficit discourses implicating poor teaching as a major contributor to South Africa’s poor mathematics education outcomes. The study highlights further that, if language is genuinely to be used as the ‘tool’ for learning it is claimed to be, synergistic opportunities for the dovetailing of insights into L2 learners’ literacy/ numeracy development require further exploration. It points to the need for ongoing professional development support for teachers of mathematics (at both pre- and in-service levels) that focuses on broadening and deepening their understandings around the linguistic, and hence epistemological, consequences of learning mathematics through an L2. Expanding mathematics teachers’ repertoires of strategies for supporting learners’ developing cognitive academic language proficiency (CALP) in mathematics (in both L1 and L2) would involve a conception of ‘academic language’ in mathematics which goes beyond a constrained interpretation of ‘legitimate’ mathematical text as that which is in texts such as curriculum documents and text books. Especially important here are strategies which foreground the value of classroom talk in assisting L2 children towards becoming more confident, competent and explorative bilingual learners, and thereby, more active agents of their own mathematical meaning-making processes. The study argues that such meaning-making processes would be further strengthened were additive bilingualism (in place of current predominantly subtractive practices) to be genuinely taken up as core to any teaching and learning of mathematics in contexts such as those described in this case study.

- Description: Many rural households living in and adjacent to forests in South Africa harvest a variety of NonTimber Forest Products (NTFPs) such as wild fruits, fibre, fuelwood, seeds, medicine and bush meat for domestic use, sale and maintaining cultural values. To promote the continued availability of these NTFPs it is important that NTFPs are well maintained and that harvest offtake is sustainable, because if it is not, then the important livelihood function that they fulfil will be jeopardized over time. The role of refugia in conserving pockets of threatened species from overharvesting has rarely been considered. Building on Shackleton et al. (2015), six applications of the concept are considered: size refugia, spatial refugia, cultural/spiritual refugia and physical/habitat refugia. I examined the prevalence and type of refugia for NTFPs at three coastal sites in the Eastern Cape province of South Africa. This was done via several community focus group discussions at each site. Here I report on the role of refugia in offering some safeguard to NTFPs by assessing harvested and non-harvested sites of refugia as well as individual plant species by measuring population density, harvest damage and size class profile. Respondents from the focus group discussions perceived a general decline in the abundance of common, widely used species over the past five decades. Decreasing rainfall and distant farming activities was reported consistently by the majority of the respondents. The most common form of refugia was spatial refugia, followed by cultural/spiritual refugia and physical/habitat refugia. Only six species were identified to be in refugia, namely Cyperus congestus, Cyperus textillis, Millettia grandis, Olea europaea subsp. africana, Phoenix reclinata, and Ptaeroxylon obliquum. Population inventories revealed that regeneration and population densities of some NTFP species in the non-refuge site were adversely affected by harvesting. Populations in refuge sites generally had the largest size classes indicating a regeneration potential but likely to impact regeneration over time if pressures are maintained. Therefore, if refuge sites keep larger individuals, NTFP populations can be maintained. Few studies have critically analyzed the concept of refugia in relation to how NTFPs can be safeguarded and the practical implication of the refuge concept needs to be considered in conservation and strategies and population models.

- Description: Rapid and widespread land cover change and the subsequent loss of the buffering capacity provided by healthy ecosystems against natural hazards has resulted in increased vulnerability to natural hazards. There is an insufficient understanding of the natural resources contribution to the resilience of poor urban communities living in informal settlements and the financial implications thereof. Thus, household strategies used to recover from the October 2012 flood shock were investigated within the informal settlements of three small South African towns using questionnaires. Within the vulnerability paradigm and the sustainable livelihood framework, the study also quantified and evaluated the relative contribution of natural resources to recovery strategies and the impacts on household financial capital. We found that natural resources contributed up to 70% to recovery of households from the flood shock, most of this being to reconstruct housing structures after the flood. Factors such as household head education level, household income, kinship level, the extent of property damage and the cost associated with property rehabilitation significantly influenced the uptake of natural resources in recovery from floods, and this was variable among settlements and towns. The main findings showed that natural resources reduced household vulnerability of urban informal settlements by providing an emergency-net function that substitutes financial capital. Their inclusion in disaster management plans and responses has the potential to contribute to the sustainable livelihoods of the urban poor in the Eastern Cape, South Africa.

This study demonstrated that anaerobic digestion (AD) followed by treatment in an integrated tertiary effluent treatment system transformed BE into a suitable solution for crop irrigation. Brewery effluent can be used to improve crop yields: Cabbage (Brassica oleracea cv. Star 3301), grew significantly larger when irrigated with post-AD, post-primary-facultative-pond (PFP) effluent, compared with those irrigated with post-constructed-wetland (CW) effluent or tap water only.

- Description: Significant debate exists within Zimbabwean studies about the basis for which people support on an ongoing basis the ruling Zimbabweans African National Union- Patriotic Front (ZANU-PF) under the leadership of Robert Mugabe. In academic literature, the party and state president (Mugabe) is typically seen as an oppressor such that any support for Mugabe is understood based on compulsion rather than consent. Genuine support for the ruling party though implies that Mugabe is a liberator. In drawing upon Zimbabwean academic literature which seeks to understand why Mugabe might be understood as a liberator, this thesis seeks to provide an innovative sociological analysis focusing on the mysticism surrounding the person and ruler-ship of Mugabe. The mysticism portrays Mugabe as being blessed by the ancestors and spirits, as having divine and sage-like qualities, as speaking for the bones of the dead heroes, and as acting as a modern day national chief who cares for his national subjects and defends his chiefdom against enemies from within or without. This portrait of Mugabe resonates with many Zimbabweans as it speaks to their everyday experiences and their longings for nation-building and national belonging. Hence, it should not be strictly understood as a ruling party ideology foisted upon citizens as a means of political deception. This is explored through interviews with a small number of ZANU-PF supporters.

- Description: The legal principles of reasonableness and the burden of proof date back to ancient times. The first codification of these principles occurred in Roman Law. The Tax Administration Act incorporates these principles in various sections. The purpose of this treatise as formulated in Chapter 1 was to determine whether there is a close connection (in practice) between tax administration (within the context of the Tax Administration Act) and the principles of reasonableness and the burden of proof. SARS acknowledges that the principles of best international practice in tax administration must be taken into account1. These principles include equity, fairness, certainty, simplicity, efficiency and effectiveness. Effective tax administration entails that a balance must be struck between the rights and obligations of the taxpayers and those of SARS2. It is important that the taxpayers and SARS strive to communicate with one another in an efficient and effective manner in order to resolve disputes between them. The treatise followed a logical approach. This entailed that the general interpretation of aspects had to be followed by the tax specific interpretation of the aspects. The general interpretation included an analysis of case law as well as research into the origins of the principles of reasonableness and the burden of proof. Reasonableness and the burden of proof do not require perfection. It is important, however, that assertions must be accompanied by evidence. The quality and quantity of evidence submitted is dependent upon the relevant facts and circumstances of a matter. The facts and circumstances of a matter also constitute determining factors in 1 Draft Explanatory Memorandum on the Draft Tax Administration Bill, 2009 at 1 in 2.5. 2 Ibid in 2.1.evaluating whether the principles of reasonableness and the burden of proof have been applied. The treatise concludes that increased efforts are necessary in order to ensure that the principles of reasonableness and the burden of proof are adhered to in tax administration. This obligation is not limited to SARS but also includes taxpayers and tax practitioners. This is closely linked to effective and efficient communication.

- Description: In this manuscript, novel green and blue sandwich-type rare-earth phthalocyanines (LnPc2) are presented. This parent green LnPc2 complex is named bis-{2(3),9(10),16(17),23(24)-tetra(4-tert-buylphenoxy) phthalocyaninato} neodymium (III) (2) and modified into blue LnPc2 complexes (3), (4) and (5) based on hexadecyltrimethylammonium ion, mononeodymium(III) diacetate and monodysprosium(III) diacetate as counter ions, respectively. These stable blue lanthanide Pc salts are highly soluble in many organic and inorganic solvents. All complexes 2, 3, 4 and 5 were studied for optical limiting for the first time using Z-scan at nanosecond regime in the visible absorption spectral wavelength (532 nm). Our studies reveal the advantage of exciton coupling in blue sandwich-type rare-earth phthalocyanines over the π-radicals (characterized by blue valence at 485 nm) in the green counterpart which are in resonance with the 532 nm wavelength for optical limiting application. Large singlet ground state to excited state absorption cross section ratios were found, particularly for complex 5 in comparison to that of complex 2.

- Description: This paper seeks to locate the place of hybrid courts in the Rome Statute’s complementarity model using the Central African Republic’s Special Courts as a case study. The introduction of the Special Courts when the International Criminal Court has already intervened in Central African Republic has raised some concern regarding the Special Courts relationship with the International Criminal Court, especially whether it may defeat the complementarity regime established under article 17 of the Rome Statute. This paper seeks to dispel this concern. It argues that the creation of the Special Criminal Court should never be perceived as an indictment to the Rome Statute principle of complementarity, but instead a useful attempt to close the impunity gap that has arisen as a result of the collapse or dysfunctionality of national criminal justice system.

- Description: In southern Mozambique a traditional wine is produced using the sap from two palm species, Hyphaene coriacea and Phoenix reclinata. Production of palm wine is one of the main livelihood activities in the Zitundo area. We examined the local production and trade of palm wine in the area. Using structured interviews we investigated the tapping activity, local management practices and the palm wine market, and assessed the incomes derived from palm wine sales and the tappers' perceptions on productivity, abundance and sales fluctuation. Tapping palms was practiced year round in five of the sixteen villages in the area and the mean number of palms tapped per day was 102 ± 52 per tapper. Tappers spent an average of 25 ± 18 h per week on tapping activities resulting in an average return to labour of R39 (± US$3) per hour. The mean, annual, net income from palm wine sales was R24,981 ± R12,094 (US$1878 ± 909) per tapper, which accounted for 85% ± 22% of the tappers' annual household income. Palm wine is a highly commercial commodity in Zitundo area, with an average commercialization index of 63% ± 23%, and is likely to help alleviate poverty in the area. Hyphaene coriacea was tapped more than Phoenix reclinata, although most tappers regard the wine from the latter to be of a better quality. The importance of palm tapping in local livelihoods and poverty alleviation needs greater acknowledgement by government and development agencies in the area, towards inclusion in sectoral development policies and conservation programmes.

- Description: Labour law knows that employers are generally in a stronger bargaining position than employees.1Therefore, labour law is largely premised on the idea of protection of the interest of employees. Fixed term employees2 as ‘atypical’3 or ‘conditional’ employees are particularly weak bargaining parties in the employment relationship. It is common practice for employers to treat fixed term and part-time employees differently to their permanent colleagues. Temporary employment relationships are often associated with the withholding of rights and benefits, lack of job security, deprivation of status and poor remuneration. Fixed term employees are also likely to be more exposed to exploitation, particularly those who are not highly skilled. 4In addition, they often do not enjoy trade union protection and are not covered by collective agreements. Most of these workers are unskilled or work in sectors with limited trade union organisation and limited coverage by collective bargaining, leaving them vulnerable to exploitation. Therefore, fixed term employees are more inclined to depend on the statutory protection enacted to ensure basic working conditions. These employees are often not recruited into trade unions due to the precarious or temporary nature of their work fixed term employees are more inclined to depend on statutory protection enacted to ensure basic working conditions.

- Description: The study was aimed at investigating the psycho-social needs and lived experiences of child headed households in the Gauteng Province of South Africa. A mixed methods approach was used to collect and analyse the data. The qualitative approach was the dominant one, while a quantitative approach was used to corroborate the qualitative findings. The quantitative data was collected through a survey. Three hundred questionnaires were distributed among children in child headed households. The child headed households were selected through simple random sampling from the databases of the NGOs and community based organisations that had agreed to participate in the study. The quantitative component of the study produced results that supported the qualitative findings. The qualitative data was collected through in-depth interviews and focus group discussions, which were conducted with purposively selected social service practitioners and community structures who were involved in work with child headed households. The resilience approach, which posits that humans are born with inherent reserves to face adversity, and the ecological systems theory, which postulates the framework in which an individual can be understood in his constant interactions and relationships within community and wider society, inform this study. The findings of the study indicate that there were various psycho social needs and challenges that child headed households faced. As Maslow postulated in his hierarchy of needs theory, inferences were made to the diverse needs of the child headed households. Physiological needs like food, clothing and finance were found to be more presenting and eminent needs for the child headed households. The study findings highlighted safety needs in the form of need for formal housing as the majority lived in informal settlements where they were exposed to much vulnerability like violence, sexual exploitation and other social misdemeanours. Other needs were esteem and familial needs, which provided a platform to foster senses of identity and belonging. However, there were other child headed households who were fortunate to have extended family members and community based organisations that assisted by providing these needs and these gestures were appreciated by the households as they ameliorated dire situations and cushioned them from absolute poverty. The findings further revealed that the psycho social challenges and needs did not only present when the household became child headed household but when their parent/s was still with them and were only exacerbated in their absence. The effects of living with parental illness, sadness and anxiety due to dramatic changes in dynamics, pain and trauma witnessing a parent dying were among the psychosocial challenges faced when the parent was still present with the children. After their departure or absence the challenges shifted and the debilitating effects of grief and loss, emotional trauma, living without adult caregiver and stigma and discrimination, were among the cocktail of challenges that the child headed households faced. However, others had support from extended family members and community structures that supported them with palliative care for the terminally ill and this afforded them the much needed respite as they focused on their studies and enjoyed their rights to be children. The study reveals that children have several coping mechanisms that exude their resilience and this includes support from social workers in promoting sustainable development goals (SDG’s) including no poverty, good health and well-being and quality education (goals 1, 3 and 4). The study highlighted that others had to supplement education with paid work (informal) whilst some ended up disengaging from their education to pursue paid employment to eke a living and support their siblings. The community and NGO’s were seen as vital components of the ecosystem that promoted the resilience of the child headed households in coping with their day to day challenges and needs. On the basis of the findings, it is recommended that the South African government should, among other things, provide a properly resourced, co-ordinated and well managed child protection system to facilitate constituency work that responds to the real needs of child headed households and SMART planning by social workers, with systemic teaming around CHH with the DSD as lead agency. The study also recommends a psychosocial approach to CHH care in the form of a model that rallies for robust assessments that social service practitioners and every structure that has the “duty to care” for CHH, can embed in their practice for improved outcomes.

The aim of this study was to review literature on Public-Private Partnership. A desktop method was undertaken in this study in order to present literature that focused on critical elements associated with Public-Private Partnership. In this way, secondary data regarding Public-Private Partnership was analysed. The sample of literature used in this study ranged from the year 2007 to year 2017. Through the search, 199 articles were identified by. Out of the 199 identified articles, 78 were duplicate articles hence were excluded. The literature review revealed that the articles that refer to Public-Private Partnerships covered the benefits, challenges as well as factors leading to PPP. The recommendations brought forward for this study were: The use of technological skills expertise should not be single sided; there should be mutual learning between the private sector and the public sector; both sectors ought to invest in technology upgrades and skill advancement for their employees in order to be aligned with the global needs; both sectors need to be politically stable before they engage on a partnership to enhance the success of Public-Private Partnership; Although service delivery is cheaper and faster in PPP’s, the quality of the service should not be compromised; the PPPs stakeholders should analyse the current environment to check feasibility before international strategies are adopted; both sectors should engage in an agile scrum meeting to discuss response to possible clashes before partnership commences.

- Description: The Q-bell is a newly developed call bell system that aims to simplify the lives of people living with disabilities by providing a means for them to easily summon assistance from caregivers when needed. The product is designed to be hands free so that a patient only must exert minimal pressure on the device with any part of the body such as the cheek to call for attention. The aim of this study was to explore and describe the experiences of disabled participants regarding the functionality of the Q-bell systems during their stay in a care facility. To achieve this aim, an exploratory, descriptive, contextual, qualitative design was decided upon. There was a paucity of similar studies and this method was deemed the most effective method to fully grasp, contextualize and interpret the experiences of the research participants following the use of the Q-bell. The research population included all people with disabilities who were in care facilities. A purposive sampling method was used to identify a small number of disabled participants in care facilities to use the Q-bell. The researcher approached selected facilities and the residents in their care who had limited to no function of their hands and arms to test the Q-bell. The participants were given the Q-bell to use for 2-3 days, after which semi-structured interviews with participating individuals were conducted. Due to difficulties the researcher had with the infrastructure at the facilities eight participants were approached and interviewed in this study. All the interviews were conducted in private, but face to face, at the bedside of each participant, in the facilities of care. Digital voice recordings of these interviews were made after informed consent being sought from the participants. Verbatim transcripts of the recordings were made and a thematic analysis using Tesch’s method, was performed by the researcher followed by a consensus meeting with the independent coder. Ethical considerations such as beneficence, justice, autonomy, informed consent was adhered to by the researcher. Trustworthiness was achieved by following Guba’s principles of credibility, applicability, consistency and neutrality. Three themes emerged from the data analysis. Theme one highlighted the participants’ experiences whilst using the Q-bell. Theme two reflected the positive characteristics of the Q-bell when compared to other call devices the participants might have used while theme three posed possible recommendations the participants had to possibly improve on the design of the Q-bell. The research report concludes with the research limitations and recommendations.

There was a paucity of similar studies and this method was deemed the most effective method to fully grasp, contextualize and interpret the experiences of the research participants following the use of the Q-bell. The research population included all people with disabilities who were in care facilities. A purposive sampling method was used to identify a small number of disabled participants in care facilities to use the Q-bell. The researcher approached selected facilities and the residents in their care who had limited to no function of their hands and arms to test the Q-bell. The participants were given the Q-bell to use for 2-3 days, after which semi-structured interviews with participating individuals were conducted. Due to difficulties the researcher had with the infrastructure at the facilities eight participants were approached and interviewed in this study. All the interviews were conducted in private, but face to face, at the bedside of each participant, in the facilities of care. Digital voice recordings of these interviews were made after informed consent being sought from the participants. Verbatim transcripts of the recordings were made and a thematic analysis using Tesch’s method, was performed by the researcher followed by a consensus meeting with the independent coder. Ethical considerations such as beneficence, justice, autonomy, informed consent was adhered to by the researcher. Trustworthiness was achieved by following Guba’s principles of credibility, applicability, consistency and neutrality. Three themes emerged from the data analysis. Theme one highlighted the participants’ experiences whilst using the Q-bell. Theme two reflected the positive characteristics of the Q-bell when compared to other call devices the participants might have used while theme three posed possible recommendations the participants had to possibly improve on the design of the Q-bell. The research report concludes with the research limitations and recommendations.

- Description: The exponential growth of technology over the past few years led to it being given prime slot at the World Economic Forum held in Davos in January 2016, with Forum founder and executive chairman Klaus Schwab coining this potentially disruptive phenomenon as the ‘Fourth Industrial Revolution’. Since then, the term Fourth Industrial Revolution (FIR) has gained ever increasing relevance and importance. Schwab (2016) emphasised that the world is on the edge of “a technological revolution that will fundamentally alter the way we live, work and relate to one another”; and that in the pure “scale, scope and complexity, the transformation will be unlike anything humankind has experienced before”. What is certain is that the FIR is predicted by many to impact significantly on jobs in the world as robotics; automation and artificial intelligence become more prolific. This shift will have a direct bearing on South Africa as well. With the challenges facing the country, such as infrastructure constraints, frequent industrial actions, rising costs and shortages of skills, the loss of further jobs should be of concern for government and the private sector alike. The outcomes of the in-depth analysis of future studies practice and theory in this research study give credence to the argument that the manner in which planning for the future of the FIR in the South African context is taking place requires profound adjustments. The development of fresh insight through the application of futures studies is essential to this planning process, as is progressively evidenced in the tendency for present day business to make collaborative decisions and strategies that are founded on and informed by futures studies. This research has tried to gain insight into the possible future of the FIR in South Africa through the creation of four scenarios towards 2035. These are outlined as follows: The Fifth Element, which is the ‘best case’ scenario, to which the country aspires; Terminator, the ‘worst case’ scenario, in which everything goes bad; The Matrix, the outlier future based on a surprising, disruptive, emerging issue; and The Day the Earth Stood Still, in which no change takes place, making it ‘business as usual’. The research furthermore endeavoured to discover the preferred future for the FIR in a South African context, as a basis for the Future Vision of the FIR in South Africa towards 2035. All through this study, Inayatullah’s (2008) pillars of futures studies were applied as a guide in mapping the present and future, further deepening and broadening the future through the development of scenarios, and, finally, transforming the future by narrowing it down to the preferred. It is up to the South African public and private sectors to determine which path is to be followed in the decisions surrounding the embrace and acceptance of the FIR as the country moves towards progress and sustainable development. Through a novel and innovative methodology, the creation of an atmosphere of trust, and the sharing of purpose, values and benefits, a national Future Vision of the FIR in South Africa towards 2035 is attainable. All stakeholders have to commit to working in co-operative partnerships, with government, society, local communities and labour striding boldly together into a world of technological, commercial, environmental and social innovation.

- Description: Economic globalisation entails the integration of national economies into one economy centred upon free International trade and the unrestricted flow of foreign direct investment.1 It has been argued by economists, politicians, business people, lawyers and many others that economic globalisation results in healthy competition amongst producers of goods and technologies around the world. This in turn results in market efficiency, cheaper, high quality goods and the increased spread of technology and wealth amongst countries. International trade aims to increase trade liberalisation, which has been seen to create higher standards of living for people as a result of greater competition amongst producers in different parts of the international globe. However whilst in support of trade liberalisation trade lawyers have warned that International trade must be fair. Unfair trade can take the form of dumping, price fixing, and certain methods of subsidisation. Unfair trade usually has disastrous effects on the domestic markets of importing countries which can result in injury to domestic industry and the national economy. Such injury can be in the form low sales, losses, company closures and retrenchments. As a result of such domestic injury, World Trade Organisation (WTO) law condemns dumping if it causes injury to the domestic industry of the importing country2 and allows importing countries to impose certain measures aimed at protecting themselves against such injury; these measures are called anti-dumping measures. However, WTO member states need to ensure that their anti-dumping frameworks are consistent with WTO norms. The principal objective of this study is to critically assess the existing regulatory framework of anti-dumping in South Africa with a view to identifying shortcomings that may result in the framework being inconsistent with WTO anti-dumping rules. In pursuing that objective, the study explores the norms and standards of the existing WTO regulatory framework on anti-dumping and ascertains the obligations of South Africa with regard to the imposition of anti-dumping measures.

The regulation of subsidies and regional trade among developing countries in the multilateral trading system: the case of export processing zones in Malawi

- Description: The paradigm shift engaged by countries in SADC and COMESA, such as Malawi, from the use of import substitution policies which were aimed at protecting their infant industries, to export led growth strategies, necessitated these developing countries to liberalise their economies. The liberalisation of these economies meant that, for them to attain development, they needed to trade more on the international market. However, with underdeveloped industries and a lack of local entrepreneurs who could provide export supplies to fill the void created by the liberalisation policies, developing countries had to look beyond their borders for investors. In pursuit of this objective, governments have been devising ways of attracting foreign direct investment which can stimulate export growth. One of the methods employed is the granting of investment incentives to would-be investors. Unlike developed countries who provide investment incentives in the form of financial incentives, developing countries grant fiscal incentives. These are incentives that reduce tax burdens of enterprises to induce them to invest in particular projects or sectors. One of the mediums of providing the incentives adopted by the developing countries is the use of EPZ schemes. EPZs provide incentives such as exemptions of direct and indirect taxes to companies that operate in the zones. However, being Members of the WTO and SADC and/or COMESA, these countries are bound by obligations regulating trade and investment as found in these Agreements. The expectation is that the fiscal incentives employed in the EPZs do not grant subsidies that are prohibited under the SCM Agreement and rules regulating subsidies in SADC and COMESA. In addition, even though the use of EPZs is not expressly proscribed under the SADC Protocol on Trade, it may be against the objectives of the Protocol - one of which is the pursuance of the inter-jurisdictional goal of cooperation in attainment of free trade among its members. Therefore, this study assesses whether the use of EPZs by some countries in the two RTAs (particularly Malawi) is in tandem with the subsidies regulation as found in the multilateral trading system and at regional level. It also assesses whether, if there is a breach of the same, it might be justified as part of the special and differential treatment accorded to developing countries by developed countries under the WTO. The study further assesses whether the use of EPZs might be against the spirit and objects of FTAs such as SADC.

- Description: Using a Karl G. Jansky Very Large Array (VLA) L-band (1-2 GHz) survey covering ∼100 deg2 of the Stripe 82 field, we have obtained a catalogue of 2716 radio AGNs. For these AGNs, we investigate the impact of galaxy density on 1.4 GHz radio luminosity (L1.4). We determine their close environment densities using the surface density parameter, ΣN, for N = 2 and N = 5, which we bin by redshift to obtain a pseudo-3D galaxy density measure. Matching the radio AGNs to sources without radio detections in terms of redshift, K-band magnitude and (g − K) colour index, we obtain samples of control galaxies and determine whether radio AGN environments differ from this general population.
