  • Description: The thicket mosaic vegetation type known as Calcrete Bontveld is now only found at three sites within the Eastern Cape Province. Consisting of thicket-like bushclumps scattered among grassy dwarf shrubland, this vegetation is isolated from other systems due to its unique geographical location and the surrounding Valley Thicket. A strong similarity between the bushclumps of Calcrete Bontveld and the adjacent Valley Thicket has led to the aim of this study, which was to demonstrate that an association exists between these two vegetation types. To investigate this, two sites, namely Grassridge (natural vegetation on a mine) and Shamwari (natural due to its status as a reserve), were selected. This provided a unique comparison of the functionality of the two vegetation types and identified key processes responsible for the existence of this association. In terms of edaphic variables, soil organic content and field capacity, values were similar between bushclumps and thicket while soil depth was the greatest in thicket at both sites. At both sites, life forms, diversity and similarity indices were similar for bushclumps and thicket. By utilizing the Island Biogeography Theory, these bushclumps show an island-type origin and the distance between them and the adjacent Valley Thicket (mainland-type), as well as their size, influenced the association between the two vegetation types. Commonality of species between thicket and bushclumps are postulated to be tied to their dispersal mechanisms and fruit types. Bushclump isolation on flat-topped ridges excluded thicket species dispersed by autochory and anemochory. Zoochorous dispersal (by birds and mammals) was the common factor in the transfer of species between thicket and bushclumps as the latter is a large resource patch for fauna. The size of the bushclumps and their distance from the thicket influenced zoochorous dispersal. Larger and closer bushclumps attracted more birds and mammals than the small or more distant ones. These effects differ at the two sites due to the complex animal interaction that occurs in the Shamwari Game Reserve as opposed to the reduced animal interaction at Grassridge. This study suggests that an association exists between the bushclumps of Calcrete Bontveld and the adjacent Valley Thicket, and is reliant on the natural zoochory that occurs at each site.

  • Description: This research project explores the possibility of using solar radiation energy to produce safe liquid water through the condensation of atmospheric water vapour for human consumption, livestock watering and also for small scale high value crop irrigation. The research activities are comprised of a literature study, comparison of similar devices in use, a design and prototyping exercise, a measure of development work to enhance the performance of the prototype and testing in Al-Batinah province in the Sultanate of Oman, where the author is currently on a work assignment. This dissertation describes the research activities performed to answer the following question: ‘Is it possible to economically produce sufficient quantities of liquid water from atmospheric vapour using only heat energy from the sun?’ This question poses a further two questions which need to be answered in the literature study. These are: ‘What is an economical price for clean drinking water?’ and ‘What is a sufficient quantity of water?’ The purpose of producing liquid water from atmospheric water vapour is an attempt to develop the technology to harvest an alternative and almost inexhaustible water source. The reason for requiring a new source of water is due to the fact that the available fresh water resources of the world are diminishing due to pollution, extensive utilisation and salination. Several references indicate that the problem is compounding itself due the increasing demand on a diminishing resource, with deepening negative effects on agriculture1, health2, economy3, industry and lifestyle4. Many future scenarios depict clean water as a scarce and expensive commodity, unaffordable to many. The condensation of atmospheric vapour is not a new concept. The literature study explores historical attempts to achieve this, as well as detailing the shortcomings of contemporary vapour condensation units as the modern state of the art. This survey covers the spectrum from large versions deployed by military and remote area construction operations to produce water for all purposes, to small desktop electrical water producing machines. The focus of the research is on a more environmentally conscious process, attempting to use a simple ejector driven device with sunshine as the energy source and water as the refrigerant. A further environmental enhancement of the concept is that of designing the machine to last for an extremely long working life, thereby diluting the carbon footprint of manufacture over a great number of years. A portion of the research is devoted to the development of a basic model which takes into account the climatic and meteorological variables to accurately predict a water harvest. The development of the model is then used to optimise the process, narrow the variability of assumptions and assist with the design. The model also serves to predict the performance of the unit in other locations under different prevailing climatic conditions. A design specification and a prototype are produced and tested. Finally the design is scrutinised using value engineering principles to reduce cost, effort and environmental impact and also to reduce the overall cost to provide a more economically viable appliance. The prototype device used in this study will use a collector area of 1 square meter, roughly equivalent to 1000 Watts of solar power under ideal conditions.

  • Description: The study examined the impact of financial liberalization on financial instability in selected SADC member countries namely South Africa, Tanzania, Madagascar and Botswana for the period 1970-2012. The Panel data methodology was adopted to establish the relationship between the two variables. Impaired loans were used to capture financial instability and financial reforms to capture the level of financial liberalization. Credit to the private sector, government expenditure, GDP and inflation were utilised as control variables The empirical findings reveal that financial liberalization leads to financial instability. The financial reforms were found to be positively related with the impaired loans ratio in almost all the specifications. It was also found that financial instability intensifies when the global financial crisis is taken into consideration. This suggests that financial liberalization can therefore be another source of financial instability in the SADC countries. The empirical results imply that policy makers should focus on reforms that give due share to the regulations rather than just simply liberalizing the financial sector.

  • Description: We report on the electrochemical behaviour of reduced graphene quantum dots (rGQDs) compared to amino functionalized graphene quantum dots (NH2GQDs). Reduction of the GQDs entails the elimination of the excessive carboxyl and hydrogen groups on the GQDs surface, thereby reducing the energy band gap. The energy band gap of graphene is directly proportional to the available oxygen atoms. The two GQD types were conjugated to a novel cobalt phthalocyanine (cobalt tris-(tert-butyl phenoxy)-mono-carboxyphenoxy phthalocyanine, CoPc) via covalent and nom-covalent interactions. The resulting conjugates were tested towards the electrooxidation of hydrazine. The conjugates are represented as rGQDs(π)CoPc, NH2(π)CoPc, rGQDs@CoPc and NH2GQDs@CoPc. The resulting conjugates were adsorbed onto a glassy carbon electrode using the drop and dry method. The lowest limit of detection (LOD) was obtained for rGQDs(π)CoPc.

  • Description: The burden of food insecurity and malnutrition is a severe problem experienced by many poor households and children under the age of five are at high risk. The objective of the study was to examine household food insecurity, dietary diversity, and child nutritional status in relation to local context which influences access to and ability to grow food in South Africa and explore the links and associations between these and household socio-economic status. Using a 48-h dietary recall method, we interviewed 554 women from randomly selected households along a rural–urban continuum in three towns situated along an agro-ecological gradient. The Household Dietary Diversity Scores (HDDS) and the Household Food Insecurity Access Scale (HFIAS) tools were used to measure household dietary diversity and food insecurity, respectively. Anthropometric measurements with 216 children (2–5 years) from the sampled households were conducted using height-for-age and mid-upper arm circumference (MUAC) as indicators of stunting and wasting, respectively. The key findings were that mean HDDS declined with decreasing agro-ecological potential from the wettest site (8.44 ± 1.72) to the other two drier sites (7.83 ± 1.59 and 7.76 ± 1.63). The mean HFIAS followed the opposite trend. Stunted growth was the dominant form of malnutrition detected in 35% of children and 18% of children were wasted. Child wasting was greatest at the site with lowest agro-ecological potential. Children from households with low HDDS had large MUAC which showed an inverse association among HDDS and obesity. Areas with agro-ecological potential had lower prevalence of food insecurity and wasting in children. Agro-ecological potential has significant influence on children’s nutritional status, which is also related to household food security and socio-economic status. Dependence on food purchasing and any limitations in households’ income, access to land and food, can result in different forms of malnutrition in children. Responses to address malnutrition in South Africa need to be prioritized and move beyond relying on food security and nutritional-specific interventions, but rather on nutrition-specific and sensitive programs and approaches; and building an enabling environment. Land availability, agriculture (including climate-smart agriculture especially in drier areas), and wild foods usage should be promoted.

  • Description: DNA-based studies have uncovered cryptic species and lineages within almost all freshwater fishes studied thus far from the Cape Fold Ecoregion (CFE) of South Africa. These studies have changed the way the CFE is viewed, as almost all stream fishes that were previously consid-ered to be of low conservation priority, because they were perceived to have broad geographical ranges, con-tain multiple historically isolated lineages, many of which are narrow-range endemics.

  • Description: The current task environment in the South African public hospitals has reconfirmed the importance of researching on the psychological environment and its influence on individual employee performance. The motivation of this study is to examine the relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within selected public hospitals in the Eastern Cape Province of South Africa. This contributes to the theoretical conceptual knowledge on how performance can be enhanced through the appropriate provision of psychological resources in the workplace and the promotion of competence, efficiency and sustainability of organisations. Survey questionnaires were used to collect data. Inferential analysis from SPSS was carried out to understand the antecedents and consequences of organisation citizenship behaviour. An overall model of the study was also identified through AMOS using structural equation modeling. Findings from the selected South African public hospitals indicate that there is a significant positive relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within the selected public hospitals. The results validate certain aspects of the Conservative frame work and the Job Demands Resources Model. The study recommends that hospital managers and supervisors should determine the social networks in their hospitals as a strategy to promote performance and organisational citizenship behaviour. Individual employees who are located at the fringes of the network must be recognised and empowered. This allows for the comparison evaluation of both individual and organisational characteristics on organisational citizenship behaviour and the promotion of slack resources which are important in maintaining a steady organisational performance which further widens organisational capacity.

  • Description: Numerous surface water bodies in South Africa face serious challenges of eutrophication despite several initiatives from government to solve the problem. Government efforts have not been successful particularly because of three issues: 1) insufficient and inconsistent water quality data and 2) the costly nature of collecting this data. Third, the limited uptake of remote sensing based technologies in water quality management due to lack of skills, as well as the lengthy and complex procedures involved in retrieving water quality parameters. This thesis aims to explore the possibilities of using satellite data and simple software for mapping and collecting water quality data. The broad goal was to determine the function of software dedicated to meet the requirements of a remote sensing-based eutrophication-monitoring system. Two specific goal were set in this study: 1. To extract software requirements from available eutrophication management documentation. This was necessary to determine the functions of the dedicated software that matches the legislative requirements and 2. To determine a design capable of handling spatial and temporal requirement of a remote sensing based eutrophication-monitoring system. The study applied Goal Based Requirement Analysis Model [GBRAM] model to extract goals from the National Eutrophication Monitoring Programme [NEMP] implementation plan document and recent publication on remote sensing of water quality monitoring conducted in South Africa. Afterwards, the study used object-oriented concepts to model suitable data objects and processes to implement spatial-temporal requirements of a remote sensing-based eutrophication-monitoring system. Based on the study findings the following are essential functions of a remote sensing based eutrophication-monitoring system. A graphical user interface that allows the user to set up a monitoring programming. Automated image processing procedures. Data assessment methods used to generate eutrophication status information. Numerous display options for viewing data in several perfectives.

  • Description: Background. HIV/AIDS remains a leading cause of death in adolescents (aged 15 - 25 years), and in sub-Saharan Africa HIV-related deaths continue to rise in this age group despite a decline in both adult and paediatric populations. This is attributable in part to high adolescent infection rates and supports the urgent need for more efficacious prevention strategies. In particular, an even partially effective HIV vaccine, given prior to sexual debut, is predicted to significantly curb adolescent infection rates. While adolescents have indicated willingness to participate in HIV vaccine trials, there are concerns around safety, uptake, adherence, and ethical and logistic issues. Objectives. To initiate a national, multisite project with the aim of identifying obstacles to conducting adolescent HIV vaccine trials in South Africa (SA). Method. A simulated HIV vaccine trial was conducted in adolescents aged 12 - 17 years across five SA research sites, using the already licensed Merck human papillomavirus vaccine Gardasil as a proxy for an HIV vaccine. Adolescents were recruited at community venues and, following a vaccine discussion group, invited to participate in the trial. Consent for trial enrolment was obtained from a parent or legal guardian, and participants aged 16 - 17 years were eligible only if sexually active. Typical vaccine trial procedures were applied during the five study visits, including the administration of vaccination injections at study visits 2, 3 and 4. Results. The median age of participants was 14 years (interquartile range 13 - 15), with 81% between the ages of 12 and 15 years at enrolment. Overall, 98% of screened participants opted to receive the vaccine, 588 participants enrolled, and 524 (89%) attended the final visit. Conclusions. This trial showed that adolescents can be recruited, enrolled and retained in clinical prevention trials with parental support. While promising, these results were tempered by the coupling of sexual-risk eligibility criteria and the requirement for parental/guardian consent, which was probably a barrier to the enrolment of high-risk older adolescents. Further debate around appropriate consent approaches for such adolescents in HIV prevention studies is required.

  • Description: There is great concern about substance use among high school learners locally and globally. Adolescents are considered to be a high-risk population as their developmental stage generally renders them more susceptible to peer influence. It is for this reason that school based peer-led substance use prevention programs are considered to be a logical intervention aimed at reducing the onset of adolescent substance use. This study was motivated by inadequate information available regarding learners‟ experiences with school-based substance use prevention programmes and their effectiveness. This was a qualitative study that was exploratory, descriptive and contextual in nature. A non-probability, purposive sampling technique was administered to grade 8-11 learners aged 13-16 who have been recipients of school-based, peer-led substance use prevention programmes for a minimum of two consecutive years. The collection of data entailed individual interviews using semi-structured interview guide and focus group discussions. Data was collected until point of saturation was achieved, and analysed using Tesch‟s thematic data analysis. The credibility of the research process and the findings was enhanced by employing a variety of data verification strategies. It is anticipated that this research contributes to a better understanding of how school-based, peer-led substance use prevention programmes can be tailored to the needs of high school learners.

  • Description: The importance of oceans cannot be overstated as they are vital for the environmental and economic well-being of South Africa. The state of South Africa’s ocean is on the decline due to increased human activities within its waters, which have caused devastation among marine resources that are limited in space, time and amount. These activities have caused elevated competition among ocean users resulting in undesirable effects such as loss of biodiversity. The challenge is not that these human activities are unregulated or unplanned, rather that there are planned and regulated on a sectoral basis by different sectors each with its own specific approach to the allocation and use of the ocean space. There is, therefore, a need for a holistic approach to ocean governance that views the ocean as a whole and not merely on a sectoral basis. The relatively new notion of Marine Spatial Planning (MSP) which establishes its authority in MSP instruments,1 has emerged as a comprehensive way to achieve this. This dissertation grapples with the questions surrounding whether the MSP instruments are consistent with the Constitution of the Republic of South Africa, 1996 (the Constitution). The dissertation departs by providing a background into the spatial jurisdiction of coastal states in the ocean space to clarify how far at sea South Africa can exercise its authority. This study concluded that even though the area of application claimed by the MSP Bill is consistent with the internationally prescribed territory of coastal states at sea, the MSP Bill should expressly state the different sovereign rights vested in coastal states by the United Nations Convention on the Law of the Sea, 1982 (‘the LOSC’) subject to the rights of other states in these waters. From here, the dissertation ventures into an analysis of which organs of state will be responsible for the development and implementation of MSP since it is an exercise of public power by the state. This part of the discussion involves inter alia an in-depth analysis of the separation of powers doctrine as far as planning matters are concerned. An essential premise is that MSP regulation requires all spheres of government to cooperate with each other. It is proposed that the MSP Bill should 1 The MSP Bill, GN 347 in GG 39847 of 2016-03-24 and the National MSP Framework for South Africa, GN 936 in GG 40219 of 2016-08-19. provide how these spheres of government should work together for the successful implementation of MSP. This dissertation then proceeds to discuss the right to equality, the environmental right, and the right to freedom of trade, occupation and profession which could potentially be impacted by the implementation of MSP. It is submitted that in the implementation of MSP, the goal must be to achieve an appropriate balance amongst these competing rights. Finally, considering the above analysis and discussions this dissertation moves to propose recommendations on how the MSP instruments can be amended to give effect to the requirements of these rights. Generally, the findings of this research reflect the consistency of the MSP instruments with the Constitution. However, for MSP to be implemented constitutionally, the proposed recommendations must be adhered to.

  • Description: This study investigated the impact of the Harmonized Social Cash Transfer Scheme (HSCT) on the children’s wellbeing specifically on their education, health, food consumption and nutrition as well as on child labour practices. The study area was Epworth District where the study sample, respondents and participants were drawn. Semi structured in-depth interviews and survey questionnaires were used to collect data. What was problematized in the study was that although social cash transfers have gained traction as a poverty alleviation tool used by many governments, their authenticity, sensitiveness and impact on child wellbeing is still being questioned. The study yielded that the HSCT generally led to the improvement of the beneficiary children’s wellbeing. In terms of education the HSCT contributed positively towards children school enrolment, school attendance, school performance and also significantly reduced school absenteeism. Furthermore, the HSCT also removed underlying impediments such as transport costs and consultation fees that prevented the poor from accessing health care facilities. However poor service delivery by government health facilities has threatened to derail initiatives and milestones achieved by the HSCT in improving the health of children. It emerged from the study that the HSCT led to the improvement of the children’s food consumption particularly in terms of quantity. However in terms of quality not much success was recorded because of the small value of the transfer money and also escalating food prices. In addition, the HSCT also led to the reduction of child labour practices as children were enrolled and kept in school hence making them unavailable for work. Money availability also saw external labour being hired to work instead of children. The study noted that the small value of the HSCT is an impediment to the full realisation of child wellbeing. Not much success was recorded in enhancing the nutritional composition of the meals because of the small equitable access to health care was not achieved since private health facilities charge exorbitant fees. Additionally child labour practices could not be totally eliminated because additional income was still needed. The study recommends that for maximum results to be reaped on child wellbeing social cash transfers need to be supplemented and complemented by interventions that strengthens the livelihoods of household. It is also vital to reinforce the goods and services supply infrastructure. This entails the government’s action in strengthening schools, government health facilities and enhancing overall food security in the communities.

This light, strong, and affordable woven bag, often referred to as “China bag” or “Chinese tote,”1 features prominently in recent artistic practices by African artists such as Nobukho Nqaba, Dan Halter, and Gerald Machona. In this essay I examine how these artistic interventions using photography, installation, video, and performance, circulating in galleries, museums, and the streets, contribute to sociological discussions about the ways in which emerging trajectories, relationships, and identities are perceived and debated in the context of the global South.

  • Description: In South Africa, the National Department of Health through its Integrated School Health Policy, use school nurses, to visit schools and perform health screening of learners which focus mainly on nutrition, eyesight and hearing. To date, this was done manually, but with the advance of technology, there is a need to investigate the use of for example, mobile applications to assist with health screening tasks. As part of the TECH4RED project in the Chris Hani district, a mobile school health assessment application was implemented and used over a period three years. As this is a new way of conducting the health screening, there is a need to understand the user experiences of the end users who interact with both the technology and the application. The objective of this study was to investigate the perceived factors that impact on the UX of the school health assessment application. The research aimed to understand the uses, advantages and disadvantages of mobile health applications. It also aimed at determining whether there are unique characteristics of the targeted end users and if so, whether such characteristics would affect the overall UX when using the application. Determining the levels of satisfaction and investigating the apparent challenges the users faced while interacting with the application provided some insights into underlying factors. A theoretical framework was constructed using existing literature. Using a case study approach, data was collected by means of end user satisfaction and user experience questionnaires. Additional data collection was done by means of an expert review to obtain feedback on the content and workflow of the school health assessment application. The resulting findings from the research included, a descriptive list of factors that impact the school health assessment application, as well as a subsequent list of recommendations for improvements. These key-findings could lead to possible guidelines, while additionally, providing valuable insight into mobile school health applications on the whole.

  • Description: The main objective of this thesis is to understand and explain the ongoing construction of livelihood activities by urban households in the low-income high-density area of Budiriro, Harare, Zimbabwe in a context characterised by systemic crisis and a general decline of the national economy. The study utilised a mixed methods research approach, which combined both qualitative and quantitative research, including a survey, life histories and focus group discussions. The thesis discusses a diverse range of livelihood activities of Budiriro households, such as formal employment, informal trading and agricultural activities, and the ways in which households seeks to diversify their livelihood portfolio. It does this by way of also examining the contemporary and historical factors influencing the livelihood activities pursued by these households, along with the shocks and disturbances encountered and experienced by households in trying to construct viable livelihoods. The thesis makes useful contributions to the existing literature on livelihoods studies. Firstly, the thesis disaggregates the households by showing the existence of three wealth categories in Budiriro and the varying livelihood strategies of households in different wealth categories. Secondly, the study highlights the significance of intra-household dynamics in Budiriro for livelihoods as well as of inter-household kinship networks, which transcend the urban space and entail multi-spatial livelihoods. Thirdly, the thesis examines livelihoods over time, such that it goes beyond a strictly synchronic examination, therefore providing a diachronic analysis of diverse and complicated livelihood pathways. Finally, the Livelihoods Framework is located within broader macro-sociological theorising including the work of Pierre Bourdieu. In this respect, important insights arise about livelihood choices and practices in the light of ongoing debates within sociology about human agency.

  • Description: The construction industry is an important industry to national development through the provision of infrastructure and creation of employment, and hence contributing to sustainable development. Nevertheless, the construction industry has a poor health and safety (H&S) and environmental record. Globally, the construction industry is a leading contributor to workplace fatalities, injuries, and disease. In Zimbabwe, the Millennium Towers accident, which resulted in 15 construction workers losing their lives, compromised the integrity of construction H&S management, and highlighted the need to improve H&S management in the sector. This study examined H&S management in Zimbabwe and developed a framework for integrating sustainability into H&S management practices. The study employed a mixed method research design involving the use of interviews and questionnaires to collect primary data from contractors, consultants, government, clients, and workers in Harare and Bulawayo. A total of 101 questionnaires were successfully completed and analysed, representing a response rate of 55.6%. The data from questionnaires were analysed with the help of the SPSS software v.23 to produce descriptive and inferential statistics. The results of the study suggest that H&S practices are inadequate as demonstrated by the extent to which workers are exposed to hazards and the occurrence of injuries, disease, and fatalities. The factors contributing to workers’ exposure to hazards and the occurrence of injuries, disease, and fatalities include, inter alia, inadequate planning for H&S, inadequate hazard identification and risk assessments (HIRAs), inadequate management of hazards, inadequate occupational health (OH) surveillance, appointment of stakeholders who do not systematically manage H&S, inadequate design HIRAs, and unsafe work practices. The problem is amplified by inadequate integration of H&S within procurement systems, which limit the extent to which contractors make financial provision for H&S. Regrettably, workplace fatalities, injuries, and disease diminish the quality of life for the injured workers, increase project cost and delays project completion. Against this background, the study investigated the integration of sustainability principles in construction H&S as a strategy to improve H&S practices in Zimbabwe. The outcome of that investigation was a strategy and interventions, and a framework for improved practices in the form of a Sustainability Framework for Construction H&S (SFCHS). The validation of the SFCHS by construction practitioners confirms the importance of the recommended practices to reducing workplace fatalities, injuries, and disease in Zimbabwe and beyond. The development of a SFCHS, as a strategy to improve H&S practices in Zimbabwe, and the validation thereof, resulted in a significant contribution to the related body of knowledge. Nevertheless, the transition to sustainable H&S practices require contractors, consultants, government, clients and workers to take a proactive role relative to the recommended practices in the SFCHS. Further studies can explore the responsiveness of sustainability factors relative to the occurrence of injuries, disease and fatalities based on selected case studies.

  • Description: Despite the prevalence of theories and research that could serve as guidelines for addressing intercultural communication challenges such as misunderstanding, ineffectiveness and inappropriateness in communication in Sino-African organisational contexts, the continued existence of these challenges suggests the inadequacy of such theories. Accordingly, in consideration of African and Chinese cultural perspectives, the aim of this study was to develop a hybrid intercultural communication congruence (HICC) framework in order to enhance intercultural communication and achieve intercultural communication congruence in Sino-African organisational contexts. In this study, intercultural communication congruence means effectiveness and appropriateness in intercultural communication. To achieve the study aim, an interpretive pragmatism paradigm was adopted, comprising a two-pronged approach of a synthesis of extant literature and theory as well as an empirical qualitative study, both underpinned by cross-cultural management theory. Based on the synthesis of literature and theory, a generic theoretical intercultural communication congruence framework underpinned by intercultural communication awareness - a state where communicants understand communication orientation and manner of communication in their own and their counterparts’ culture - was developed. A further contribution was a theoretical contextualisation of the generic theoretical intercultural communication congruence framework, resulting in a theoretical framework for intercultural communication awareness in Western, African and Chinese cultures and a theoretical intercultural communication congruence framework specific to Sino-African organisational contexts. Thereafter, with the aim of validating the intercultural communication awareness dimension of the theoretical intercultural communication congruence framework specific to Sino-African organisational contexts, an empirical study was conducted with a sample of seven African and eight Chinese experts using indepth interviews with open-ended and semi-structured questions. Based on qualitative content analysis, six intercultural communication awareness enablers or conditions that enable people to understand communication in different cultures and contexts for the purposes of attaining intercultural communication awareness emerged. These were cultural orientation, manner of communication, orientation to rules and protocol, individual dispositions, intercultural communication influences and intercultural communication variations. An integration of the intercultural communication awareness enablers into the generic theoretical intercultural communication congruence framework results in an updated generic theoretical intercultural communication congruence framework. Then, informed by the updated generic theoretical intercultural communication congruence framework, a further contribution of this study was an empirical verification of the intercultural communication awareness dimension of the theoretical intercultural communication congruence framework specific to Sino-African organisational contexts to result in a final hybrid intercultural communication congruence framework for Sino-African organisational contexts supported by the perspectives of those involved in interaction, rather than predetermined standards of other cultures. Empirical findings suggest that both African and Chinese colleagues maintain a sense of collectivism in the Sino- African organisational context, although this is demonstrated differently. In addition, African colleagues display a blended manner of communication characterised by a mix of Western and African ways while the Chinese manner is contextual and governed by roles and relationships. In African culture, rules and protocol are negotiated, aimed at social maintenance, while strong cultural patriotism ensures strict adherence in Chinese culture. In respect of individual dispositions, African people are seen as open and accommodating while the Chinese disposition could be described as closed and ambiguous. Also evident in the findings is the existence of within-culture differences and influence of noncultural factors on intercultural communication that should be addressed in order to achieve intercultural communication congruence. Finally, the frameworks developed and the methodological processes followed will stimulate academic debate and raise numerous questions for future research. Immediate future research could be geared towards refining the concepts of intercultural communication awareness, intercultural communication congruence and the hybrid intercultural communication congruence framework for Sino-African organisational contexts. At a management practice level, intercultural communication awareness insights provide a reference point for intercultural communication enhancement strategies and interventions in Sino-African organisational contexts.

  • 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.
