  • Description: Labour markets ar ound the world have witnessed a great change in labour relations. The introduction of globa lisation, increased competition and technological advancements has caused business organisations to change their employment methods. While trying to survive and remain profitable, employers have adopted a new form of triangular employment relationship. Thi s form of employment relationship known as labour broking and which forms part of the Temporary Employment Services (TES) involves a relationship between the worker, labour agent (broker) and a client c ompany. Although it may seem like a good strategy for business organisations, the change in employment relationships has had negative effects and contributed to labour market dysfunctionalities . This has resulted in critics of labour broking calling or an end in labour broking and supporters of labour broking asking for better regulation of the industry. Labour markets are me When it comes to analysing labour broking and its impact on labour market functionality in South Africa. Scholars and analysts such as Budlender ( 2013 ) and Bhorat, Lil enstein, Oosthuizen , and Thornton ( 2016 ) have used the Neoclassical , New Institutional Economics and Marxist approach es. The current views on labour broking and the current schools of thought fail to look at the underlying behavioural aspect of labour brokers and the client c ompanies. Hence making it easy for labour brokers and their client companies to continue with their unscrupulous activities. However, this t hesis adapted the Veblenian Dichotomy framework which focuses on understanding the role of the evolutionary proce ss and the role of institutions in shaping economic behaviour. The Veblenian dichotomy shows that power plays an important role in how labour markets are run. Similarly, behaviour also influences the manner in which labour brokers and client companies trea t workers. And lastly the Veblenian dichotomy shows that in order for the industry to be run better there has to be change in the behaviour and cultu re of the labour brokers and client companies . This view allows for deeper analysis of the reasons for the flour ishing nature of labour broking and the rationale behind the behaviour of economic players and attempts to provide solutions on how labour brok ing can be correctly administered in South Africa. The Veblenian Dichotomy categorises institutions into t wo sets, namely the ceremonial institutions and instrumental institutions. Where Ceremonial institutions are said to be institutions that foster the interests of business such as profitability and earning of free income, even if there is no corresponding i ncrease in production. While Instrumental institutions, usually working through the influence of technology, address the interests of the common pers on and the labourer as well as business (Waller, 1982; Foster, 1981; Veblen, 1919). These two systems of va lues and institutions are antagonistic and the relative strength of one to the other determines economic outcomes and in whose interests the outcomes would be (Waller, 1982; Foster, 1981; Veblen, 1919). The Veblenian Dichotomy further looks at ceremonial encapsulation which occurs when ceremonial systems prevail over instrumental systems. Ceremonial encapsulation presents the hypothesis that the insti tutional structure will absorb new technology only to the extent that it can do so without disrupting the e xisting value structure (Waller, 1987; Bush, 1979.) The thesis use d various sources , such as working papers, public hearings, court cases, trade union submissions, integrated reports from companies, employee submissions and media publications on the debate about labour broking whether labour broking and applied the Interpretative Phenomenological Analysi s (IPA) research approach, in the process of data collection and analysis . The thesis further applied thematic analysis to derive themes that would be used to analyse the impact of labour broking on labour market functionality in South Africa. The emergent themes and subthemes were Exploitative lab our relations subthemes; job Insecurity, increased financial burden and no skills development. The second theme was; Competitive advantage and the subthemes were; i ncreased profits and organisational efficiency. The third theme was l abour market efficiency and the subthemes were. E mployment creation and labour market flexibility. And, the last theme was a mbiguous l abour regulation s with subthemes; n o freedom of association and a tool for circumventing labour regulations . Lastly, Tool’s (1994) criteria of j udgement for institutional adjustments was used to evaluate the emergent themes and to evaluate the impact of l abour broking on the overall welfare of individuals, which includes determining whether employees in the TES sector gain skills and improved stan dards of living. The findings of the research the TES sector is characterised by ceremonial values. Ceremonial values (as mentioned in section 3.3) are those values that are warranted by the ways of life that prescribe status and hierarchies and unpleasant distinctions to apply value and status on other people (Bush, 1987, 1988; Ayres, 1967). Thus changing the way in which labour brokers conduct themselves or handle labour broking activities would prove to be difficult . T he power that is mostly used in TES employment sectors is condign power. Condign power is explained as the form of power that is predominantly used in ceremonially encapsulated markets. And it involves making use of punishment or fear in order to get people to do something. This is because w orkers in the TES sector are forced to submit to conditions that they would not normally have submitted to if t hey did not have a fear of losing their jobs. This supports existing literature which shows that in the TES sector, TES employers use force and p ower in order to get the workers to do something, and this results in a master - servant relationship between the employer and the employee. Furthermore, the protests that erupt in the TES sector agree with Marxist theory which notes that the frustrations in the way workers are treated would result in a revolution of the working class against the employers. However, now, workers have not been able to overcome the employers and take over the industry. In addition to what current literature says, the research found that some managers make use of labour broking as a way of manifesting their exploitative characteristics on the labour market, thus creating information asymmetries in order to advance their own personal needs. Situations such as these reve al characteristics of opportunistic behaviour, which is perpetuated by the imperfect flow of information. This means th at the market is imperfect, and imperfect markets are characteristics of dysfunctional labour markets. The research also found that it i s the South African Constitution that protects labour brokers and client companies from accounting for the unfair treatm ent of workers. Labour brokers and client companies rely on the South African Constitution to defend them when it comes to banning labou r broking. This is because section 22 of the Constitution talks about the right of every individual to trade freely in S outh Africa (Kutumela, 2015). When institutional adjustments do not meet the requirements of the progressive criteria, it means they are regressive. Based on the data that was collected and the responses and remarks of the workers, trade unions, and trade union federations, it can be said that TES employment and labour broking hinders labour market functionality. Hence, it can be concluded that, due to the characteristics mentioned, labour broking does indeed have a regressive element which hinders labour m arket functionality. An area for further research for TES employment would be to look at the impact of the amendments to the Labour Rela tions Act. Specifically focusing on the Constitutional Court ruling, which forces labour brokers to treat employees who have been employed for longer than three months as permanent employees.

  • Description: The worrying existence of incidences of student retention, poor pass rates and an increase in repetition rates is a cause for concern for institutions of higher learning in South Africa. The problem of student retention is not new in our institutions of higher learning. Support structures, strategies, and policies need to be developed for different academic and social challenges that students face daily. This study explores the need for academic support at Rhodes University; it also explores the internal and external problems that students face, the perceptions and experiences of students on academic support available to them. The study implemented a narrative research approach implanted within a qualitative research framework. Data was collected through a questionnaire, and narrative interviews. Tinto’s Student Integration Model was used to analyse the data in this study and was supplemented by Louw’s conceptual framework model and Swail’s Geometric Design of Student Persistence. These three models position the student experience as the foundation for academic support programmes and development. The study argues that as long as effective and adequate academic support is lacking, students will continue to experience difficulties in completing their studies. The findings from the study reveal that at present, Rhodes University provides support to students who are in extended studies. However, this support system disadvantages many students, notably those not in the extended studies programme. As a result, such students are not supported through strategies and structures that extended studies students receive. Furthermore, the data generates internal and external problems that student face daily, as a result, the findings showed that there is a need for academic support at Rhodes. The study recommends that Rhodes University must establish an academic unit that will provide academic support to all students registered in the university.

  • Description: Chalcone family molecules are well known to have therapeutic proprieties (anti-inflammatory, anti-microbial or anti-cancer, etc). However the mechanism of action in some cases is not well known. A virtual library of this family of compounds was constructed using custom scripts, based on the aldol condensation, and this library was modified further to analogues by expansion of the α,β-unsaturated ketone linker. Acetophenone and benzaldehyde derivatives which are available and purchasable were used as a base to design the chalcone virtual library. 8063 chalcones were constructed and geometrically optimized with Gaussian 09. Their physicochemical characteristics linked to the Lipinski rules were analyzed with Knime and CDK. The entire library was after docked against several targets including HIV-1 integrase, MRSA pyruvate kinase, HSP90, COX-1, COX-2, ALR2, MAOA, MAOB, acetylcholinesterase, butyrylcholinesterase and PLA2. With the exception of MAOA, which does not have a crystal structure ligand, all dockings were validated by redocking the original ligand provided by the literature. These targets are known in the literature to be inhibited by chalcone-derivatives. However, specificity of the particular known chalcone inhibitors to the particular targets is not known. To this end the performance of the generated chalcone library against the list of targets was of interest. The binding energy of ligand-protein complexes was generally good across the library. Statistical analysis including principal component analysis and hierarchical clustering analysis were made in order to investigate for any physical/chemical characteristics which might explain what chalcone features affect the binding energy of the ligand-protein complexes. The spherical polar coordinates defining the orientation of the binding poses were also calculated and used in the statistical analysis. The statistical analysis has allowed us to hypothesize the importance of these radial distances and the polar angles of key atoms in the chalcones in binding to the pyruvate kinase crystal structure. This was validated by the docking of another small library of compound models in which the α,β-unsaturated ketone chain of the chalcone was replaced by incrementally longer conjugated chains. Further studies on the chalcones themselves reveal rotameric systems in both cis and trans-configurations (which may impact binding), and also studied was the effect of Topliss-based modification and its impact of binding to HSP90. Molecular dynamics confirmed good binding of identified chalcone hits.

  • Description: The forthcoming Square Kilometre Array is expected to provide answers to some of the most intriguing questions about our Universe. However, as it is already noticeable from MeerKAT and other precursors, the amounts of data produced by these new instruments are significantly challenging to calibrate and image. Calibration of radio interferometric data is usually biased by incomplete sky models and radio frequency interference (RFI) resulting in calibration artefacts that limit the dynamic range and image fidelity of the resulting images. One of the most noticeable of these artefacts is the formation of spurious sources which causes suppression of real emissions. Fortunately, it has been shown that calibration algorithms employing heavy-tailed likelihood functions are less susceptible to this due to their robustness against outliers. Leveraging on recent developments in the field of complex optimisation, we implement a robust calibration algorithm using a Student’s t likelihood function and Wirtinger derivatives. The new algorithm, dubbed the robust solver, is incorporated as a subroutine into the newly released calibration software package CubiCal. We perform statistical analysis on the distribution of visibilities and provide an insight into the functioning of the robust solver and describe different scenarios where it will improve calibration. We use simulations to show that the robust solver effectively reduces the amount of flux suppressed from unmodelled sources both in direction independent and direction dependent calibration. Furthermore, the robust solver is shown to successfully mitigate the effects of low-level RFI when applied to a simulated and a real VLA dataset. Finally, we demonstrate that there are close links between the amount of flux suppressed from sources, the effects of the RFI and the employed solution interval during radio interferometric calibration. Hence, we investigate the effects of solution intervals and the different factors to consider in order to select adequate solution intervals. Furthermore, we propose a practical brute force method for selecting optimal solution intervals. The proposed method is successfully applied to a VLA dataset.

  • Description: This thesis examines how meanings of masculinity and femininity are negotiated by South Africans on a social media platform linked to a popular local tabloid newspaper. In particular it explores conversations surrounding the Ben 10 phenomenon on the Daily Sun’s Facebook page. A Ben 10 is commonly understood as a young man who enters into a sexual relationship with an older woman, mostly in township settings, and readers engage vociferously over the meanings of such relationships. Using a constructivist understanding of gender, a thematic analysis is used to examine the Facebook comments on the Daily Sun’s most popular Ben 10 stories. South Africa’s constitution promotes the right to gender equality and freedom, which contributes to the normalisation of sex in public conversations and political debate. However, with high levels of unemployment and poverty in South Africa, the narrative of masculine success through work remains relatively unattainable. This tension between the narrative of male-bread winner through work and the reality of South Africa’s poverty and unemployment has been referred to as the crisis of masculinity. This thesis will argue that tabloids can play a strong political role by providing an alternative public sphere and that they can also assist their readers in coping with life in a democratic society by creating an imagined community of people sharing common experiences.

  • Description: This study presents age distributions representing populations of adult Loligo reynaudii, together with the results of spawning and commercial catches to assist in understanding the beneficial role of the closed season. The results were based on 791 samples collected during three closed seasons (November: 2003, 2004 and 2005) and out of closed season during April/May 2005. Age and predicted growth were examined by counting daily rings on statolith microstructures. The age in days after hatching ranged from 168 to 484 days (71-425 mm) in males and from 125 to 478 days (83-263 mm) in females. Average age at spawning was found to be 323 days in males and 316 days in females. Population estimates of growth rates were best described by a linear growth model which revealed that males grew faster than females in length as they grew older with growth rate ranging between 0.63 to 0.83 mm per day for males and between 0.22 to 0.32 mm per day for females. Back-calculated hatch dates and later egg-laying events for parental populations were determined. Results from back calculated egg laying dates (presented as percentage of frequency of all laying dates) indicated a highest total of 36%, 39% and 15% of eggs from all samples were laid during the closed season and nine days after the closed season during year 2003, 2004 and 2005 respectively. Monthly commercial total catches (2002-2005) showed an increase from November soon after the fishery resumed, up until the month of January. Daily catches were highest in November (up to 290 tonnes) relative to the daily catches observed in December and January in all the years. Results led to the conclusion that the closed season (25 October to 22 November) is beneficial for both the chokka resource and the fishery. This is because: a) there is time for enough spawning biomass to accumulate, which subsequently results in high catches (good fishery), in the current year, best immediately after season opens in November; b) there is a link in the results between egg laying dates in the period of closed season and immediately afterwards, and the magnitude of catches in last nine days of November.

  • Description: As a “Non-Annex 1” country, there was no obligation for South Africa to reduce its carbon emissions. South Africa undertook, of its own volition, to take measures to reduce 34% of the carbon monoxide emissions by 2020 and 42% by 2025 respectively. In response, South Africa promulgated the Carbon Tax Act, No. 15 of 2019. This study seeks to answer the question: After analysing the range of environmental taxes levied in the Scandinavian countries (Denmark, Finland, Norway and Sweden) and in South Africa, are there lessons that can be learnt for South Africa? In answering this question, the carbon tax structure in South Africa and in selected Scandinavian countries is analysed, together with existing environmental taxes and the related policies, using a literature study. What is evident from the Scandinavian countries studied, is that environmental taxes have distributional effects and are effective in reducing carbon emissions. The major result of the study was that the real weakness of the newly introduced Carbon Tax Act is that in both in the first and second phase of its implementation, the carbon tax rate is too low to send an appropriate signal to the market and would not have the desired outcome. In addition, there are currently no guidelines that inform the revenue recycling technique to ensure transparency of revenue usage, improved energy management, or how the Carbon Tax Act will promote environmental quality. A major concern is that carbon tax revenue will not be ring-fenced. Given that South Africa is a developing country and depends mainly on non-renewable energy, it is inevitable that most of its sectors will be subject to the carbon tax. A plausible approach is the one that promotes the idea of taxing those more heavily that contribute most to environmental degradation and are highly energy concentrated, to promote parity between the harm to the environment and the taxes levied to redress the harm.

  • Description: Financial institutions are faced with increasing competition as there has been an increase in new entrants in the industry, therefore a battle of market share in banking is in progress. Digitization is fast changing how customers perceive value, customers have become spoilt for choice and thus banks have to implement strategies that will help them to increase their market share by keeping the customers they currently have and strategies that help them to acquire more customers. A strategy on its own will not support organizational goals, if it is not adopted by the executers – the employees on the ground. It is important for leaders to support the strategic goals of an organization by ensuring that the goals become a culture, a way of doing things in that organization. This study is an analysis of how leadership shaped a culture of customer centricity in the branch of a bank. The objectives of the study were to: (1) To describe the culture of customer centricity that was cultivated by the branch manager; (2) To analyse what the leader pays attention to, measures and controls on a regular basis, in support of a culture of customer centricity; (3) To analyse how the leader conducts deliberate role modelling, teaching and coaching in support of a culture of customer centricity; (4) To analyse whether - and if so how - the quality of the dyadic relations between the leader and her followers enables or disables the effect of cultural mechanisms on the culture of customer centricity; and (5) To analyse how the leader built high quality relations with her followers The study took the form of a case study of a branch of a bank, where nine universal bankers and their former leader were interviewed. The data were then analysed using a deductive thematic analysis. The findings met all objectives of the study and the findings supported the propositions. The findings also discovered that reward and recognition contributed to the shaping of a culture of customer centricity. In conclusion the limitations and delimitations of the study are acknowledged, and recommendations are made. The study contributes towards the Social Exchange Theory (SET) and demonstrates how high-quality leader member exchange (LMX) relations can be developed. Several recommendations are made for further studies on factors shaping a culture of customer centricity, and implications for management are considered.

  • Description: Visualisation plays a central role in developing mathematical ideas because it can be used to make these ideas explicit and visible, and thus has the potential to advance understanding. This study centred around the GeoGebra Literacy Initiative Project (GLIP), a teacher development initiative in Mthatha that aimed to grow and develop appropriate Information and Communication Technology (ICT) skills in teachers, to harness the teaching and learning potential of GeoGebra. GeoGebra is a dynamic geometric software package that is very interactive and makes use of powerful features to create images which can be moved around the computer screen for mathematical exploration. This research project was located within GLIP and analysed how GeoGebra applets develop conceptual and procedural understanding in selected Grade 11 learners. One aspect of GLIP was for teachers to use GeoGebra applets that they had developed themselves and implemented in their classrooms in pre-determined cycles that were aligned to the curriculum. My study specifically focused on how the selected learners made use of these applets and explored how learning had taken place in terms of developing mathematical meaning-making. This interpretive research study was designed as a case study. The case was a cohort of selected Grade 11 learners who had been taught by GLIP teachers, and my unit of analysis was the learners’ interaction with the applets. A screen capturing software package was used to capture learners’ interactions with the GeoGebra. My data consisted mainly of recorded observations and interviews. An analytical framework derived from the works of Kilpatrick, Swafford, and Findell (2001) and Carter et al. (2009) guided and informed the data analysis of the learners’ activities with the GeoGebra. The theoretical orientation of this study was constructivist learning. An in-depth analysis and detailed descriptions of the participants’ interactions enabled me to gain a comprehensive understanding of their meaning-making processes in a technological classroom context. An analysis across the participants identified distinguishable patterns or differences in the development of the learners’ mathematical proficiency and making sense of mathematical ideas. The research argued that technology enabled visualisation was a powerful tool to not only enrich mathematically activities, but to also enrich conceptual and procedural understanding. The findings recognised that exploration of, or manipulation on mathematical objects in GeoGebra was a key activity in the participants’ meaning-making process. It also enabled learners to offer self-proclaimed theories

  • Description: This study aimed to analyse the indicators disclosed in the Integrated Annual Reports (IARs) of selected South African retailers. This was firstly done by identifying the six capital and governance indicators retailers report on in order to analyse the commonalities and differences between them, secondly by identifying and assessing evidence of integrated thinking and lastly by making recommendations for optimal retail sector reporting. IARs from Pick n Pay Stores Ltd, Shoprite Holdings Ltd, Spar Group Ltd and Woolworths Holdings Ltd were analysed using content analysis. The results found noteworthy differences in IAR composition in terms of report length and the sections retailers devoted more or less of their report to. Governance and Remuneration indicator disclosure did not allow for broad comparison among all four retailers. In terms of indicator disclosure few indicators were disclosed by all retailers, whilst many were only disclosed by one retailer. Disclosures related to all six capitals were found, yet some indicators were disclosed excessively. Paradoxically, insufficient disclosure of indicators that are easily measurable and low levels of negative or unfavourable indicator disclosure was also apparent in this study. The comparability of indicators was influenced by the aggregation and disaggregation of indicators as well as the lack of consistency in the terminology used in IARs. Indicator disclosure also revealed several trends in the South African retail industry. This research identified the following six themes related to integrated thinking in the sample IARs. Retailers understand the connection between capitals, express consideration for multiple stakeholders and appreciate the context in which they operate, to some extent. Retailers were also found to have different interpretations of sustainability as part of their strategy and risk management whilst the completeness and consistency of information disclosed and retailers’ conceptualisation of value-added in IAR has not yet developed to the same extent across the retail industry. This study finally makes recommendations that may be used for optimal retail sector reporting with regards to the integrated reporting process as well as the integrated report itself. Addressing the former it is recommended that: integrated reporting be viewed as a means to build an internal understanding of their sustainability practices; integrated thinking be included as part of their strategic planning process; all capitals be considered in decision making; communication be established with others in the retail industry and that retailers engage with the IIRC on integrated reporting issues. In terms of the IAR itself, it is recommended that retailers ensure consistency in the terminology used and that the disaggregation of indicators is done in a consistent way. Retailers should include a balance of positive and negative disclosures as well as context-based indicators and seek assurance of the social, environmental and ethical information in their IARs. Finally, retailers need to set measurable sustainability performance targets and link them to specific performance indicators. The results of this study are not without limitations. The identification and categorisation of an indicator was largely based on the researcher’s own judgement in the content analysis process and can be highlighted as the main limitation of this research.

  • Description: The use of passive network sensors has in the past proven to be quite effective in monitoring and analysing the current state of traffic on a network. Internet traffic destined to a routable, yet unused address block is often referred to as Internet Background Radiation (IBR) and characterised as unsolicited. This unsolicited traffic is however quite valuable to researchers in that it allows them to study the traffic patterns in a covert manner. IBR is largely composed of network and port scanning traffic, backscatter packets from virus and malware activity and to a lesser extent, misconfiguration of network devices. This research answers the following two questions: (1) What is the current state of IBR within the context of a South African IP address space and (2) Can any anomalies be detected in the traffic, with specific reference to current global malware attacks such as Mirai and similar. Rhodes University operates five IPv4 passive network sensors, commonly known as network telescopes, each monitoring its own /24 IP address block. The oldest of these network telescopes has been collecting traffic for over a decade, with the newest being established in 2011. This research focuses on the in-depth analysis of the traffic captured by one telescope in the 155/8 range over a 12 month period, from January to December 2017. The traffic was analysed and classified according the protocol, TCP flag, source IP address, destination port, packet count and payload size. Apart from the normal network traffic graphs and tables, a geographic heatmap of source traffic was also created, based on the source IP address. Spikes and noticeable variances in traffic patterns were further investigated and evidence of Mirai like malware activity was observed. Network and port scanning were found to comprise the largest amount of traffic, accounting for over 90% of the total IBR. Various scanning techniques were identified, including low level passive scanning and much higher level active scanning.

  • Description: In theory, notions of public history and participatory journalism signal the ability of users to become active collaborators in the journalistic process with a degree of agency and authority over media content. Similarities in public history and participatory journalism are manifested in audience participation where the traditional and hegemonic boundaries between readers and journalists/historians are challenged. In this thesis, I present Purple Truths, a digital public history website about the School of Journalism and Media Studies at Rhodes University, that highlights multivocality and plurality. It allowed for democratisation of the historical narrative by inviting audience participation to historical inquiry on a digital platform. It was constructed as a case study for the thesis to investigate participatory processes. Using a five-dimensional model developed by Netzer et al. (2014) for the construction of participation on news websites, I identified five major participation features that revealed how and where participation was happening on the website. The features were mapped and tabulated according to Carpentier’s (2011) maximalist/minimalist dimensions of participation (access, interaction and ‘real’) to determine the degrees of participation in this study towards the aim of using the Purple Truths website to democratise the historical narrative. My findings suggest that despite a diversity of strategies, the study did have to rely on existing norms and practices of editorial decision-making, even in the context of digital media, and significant stages of the news-production process (selection/filtering) remained in the hands of researcher/editor. Maximalist participation, demonstrated as equalised power relations in decision-making, has a utopian dimension and is difficult to translate into practice. However, participation research requires further investigation in the digital humanities in South Africa to explore notions of democratisation of the narrative in academic and social praxis as sites of interdisciplinary democratic renewal

  • Description: The study analysed self-help agricultural projects in Rothe, Lesotho to ascertain whether they improve the quality lives of Rothe villagers. As much as government driven self-help projects in Lesotho contribute to growing the rural economy, there is limited research that looks the sustainability of these interventions. Much of the literature in Lesotho reveal that self-help agricultural projects have focused on people being provided with food-for-work, or cash-for-work, these offered little benefits and temporary relief for hunger for beneficiaries. This study seeks to understand how self-help agricultural projects can sustainable improve the lives of Rothe community in Lesotho. The study drew from Sustainable Livelihoods Approach to understand self-help agricultural projects in Rothe, Lesotho. The study employed a qualitative case study approach, supplemented by purposive and snowball sampling methods and semi-structured interviews to select and interview self-help project beneficiaries and Field Officers of RSDA in Rothe Village. The findings revealed that self-help agricultural projects are alternative development interventions for improving the quality lives of poor rural villagers. These development interventions enable people to access livelihoods resources, assets, and social capitals that are important to improve, and sustain livelihoods. Additionally, they improve capabilities of the poor, and contribute to their overall development. The thesis concludes that these development interventions have a role to play in alleviating rural poverty lives as a way to ensure equitable distribution of resources. The study recommends that the government, people on the ground and RSDA should work together to strengthen people’s capabilities through self-help agricultural projects to promote welfare and well-being of rural people.

  • Description: Food price volatility, ecological shocks and unprecedented levels of hunger and obesity are increasing concerns within food security governance, as is the emergence of food sovereignty in broadening critical discussions around food, water, energy and environmental crises. This thesis analyses this changing terrain in the context of South African policy. It analyses shifts in policymaking and the capability of South Africa’s food security policy frameworks to include food sovereignty principles and in so doing support genuine long-term food security. A shift in policy priorities from household production, trade and income opportunities towards social safety nets and nutritional interventions is identified. This focus is constrained by an inability to affect structural changes within a deeply inequitable food landscape. An emphasis on commercial farming and unwillingness to challenge large agribusiness, value chains and corporate retail has enabled social differentiation in access to food and the country’s colonial land dispensation to continue. Consequently, markets have continued to be antipathetic to the needs of poor producers and consumers in South Africa. To overcome these structural constraints, food security policy needs to be framed within a more radical normative agenda. This is important for challenging inequitable power relations and asserting the social and ecological imperatives of healthy food systems. Food sovereignty has significant potential to support a normative agenda by supporting the multiple farming practices, enterprises and livelihood strategies pursued by poor farmers, the unemployed and working poor whilst preserving sensitive environments for future generations. Determining the future of food security is not the privilege of the few with economic clout or power to govern but the right of all. The incorporation of food sovereignty principles in policymaking is therefore paramount for achieving genuine long-term food security.

  • Description: This research explored whether there is any evidence of reporting of organisational resilience within the integrated reports of a large state-owned enterprise. The organisation chosen for the research was Eskom. The integrated annual reports of Eskom for 2016, 2017 and 2018 were examined. Direct and indirect evidence of organisational resilience was sought within the organisations integrated reports. The direct reporting of organisational resilience was located by using a PDF word search. A thematic content analysis was used to perform the search for indirect reporting of organisational resilience. Three main themes to represent organisational resilience that were identified beforehand were used to identify the indirect reporting of organisational resilience. Namely, transformability, adaptability and persistence. Sub themes of general and specified resilience were also identified during the research process. The literature review discusses the themes in detail, and also introduces communication and integrated reporting. Evidence of both direct and indirect organisational resilience was identified in all three years studied. Evidence of all the main themes and sub themes was found within the indirect reporting of organisational resilience. The main limitation of the study is that although evidence of reporting of organisational resilience was found, this evidence does not provide any indications of the level of organisational resilience within Eskom. A number of recommendations to Eskom management are made at the end of the research. What is interesting is that integrated reports are not designed to report on organisational resilience. However, the research showed clear evidence of reporting of organisational resilience within all three years researched. Potentially indicating that the integrated annual reports are a useful method of sharing information regarding organisational resilience with stakeholders. An additional benefit is that communication with stakeholders is simultaneously contributing to the enhancement of the organisations resilience.

  • Description: The growth in the mining sector post 1994 saw many CEO s enjoy exorbitant levels of financial prosperity particularly in relation to th e mining workforce . The pay disparity between the remuneration of CEO s and the average worker contributed to instability and labour unrest. While there has been extensive research conducted on the relationship between CEO remuneration and company performance, questions around the justification of exorbitant CEO remuneration levels have persisted. One of the shortcomings of these studies have been understanding company performance as limited to financial indicators. For this reason, Resource - Based theory was used in this study to focus on CEOs as tangible, heterogeneous and immobile assets, who could influence company performance by creating a firm’s competitive advantage. In order to investigate this, a mixed - method research design was utilised to ascertain the relationship between CEO remune ration and company performance. The data for the quantitative study was collected using an archival method by sourcing secondary data obtained from the sampled companie s’ annual integrated reports. Statistical tests were performed to test the relationsh ip between CEO remuneration and company performance of mining companies listed on the JSE over the period of 2014 to 2018. This was followed by the qualitative thematic analysis which utilised online information published about four CEOs sampled according to their pay/performance relationships (namely high earning/high performing; high earning/low performing; low earning/high performing and low earning/low performing). The VRIO framework was utilised in conjunction with the thematic analysis to assess the extent to which each of the selected CEOs could be identified as valuable, rare, inimitable and organised. Finally, t he demographic characteristics and leadership attributes of these CEOs were collectiv ely aligned to particular l eadership archetype s. This study found that despite company performance levels experiencing negative growth and volatility, CEO remuneration remained stable and experienced positive growth throughout the period . The qualitative analysis and the application of the VRIO framework wa s conducted in order to explor e reasons why this disparity may continue to exist. The analysis of the differences in demographic characteristics and leadership attributes between these four CEOs provided a possible j ustification for the disparity in t he levels of remuneration. It was found that some CEOs high levels of remuneration could be justified by virtue of their well - developed leadership skills. In particular CEOs need softer skills (such as communication, openness, relationship - building and stakeholder engagement) and to draw on the communicator, builder and coach archetypes in order to create a sustained competitive advantage within companies.

  • Description: The biological characteristics of chokka squid, Loligo reynaudii, sampled off the south coast of South Africa, were compared between 1994 and 2017 to ascertain any temporal changes using analysis of length frequency (LF) data over 15 years (1996–2017), and mantle length (ML) and total weight (TW) relationships over 9 years (1994–2016). To investigate feeding, two caecum colours were chosen for analysis (white: no food ingested, and yellow: six to seven hours after food ingestion). Other factors were kept constant throughout: similar sampling period of 60 days in spring-summer, similar depths and areas sampled, and identical maturity stage. Anecdotal evidence from fishers suggested that the length frequency and ML_TW relationship of chokka have changed over years, with possibilities to be linked to fishing activities and environmental conditions. Also, there is evidence in the published literature that both fisheries and environment may influence length distributions in populations of fish and cephalopods over time. The results from this study showed no significant differences between length frequencies over the time series. However, a significant decrease in length frequencies between 2014 and 2016 was noted when paired data was analysed by Anova (2014:2015, 2014:2016 and 2015:2016), which was initially noted in kernel density, Figure 2, hence an additional analysis was done. These changes were not linked to sea temperature (at 9 m, 14 m, 18 m, and 21 m depth strata), with not significant (P>0.05) results when temperature was analysed by t-test between 2002 and 2015. There was also a weak correlation between length frequency and the total squid catch in a given year (F Statistic (df = 1; 13) is 3.686 and 5.394 for males and females respectively, R² is 0.221 for males and 0.293 for females), but too weak to interpret, given the lack of other supporting data and the short time series. The ML_TW relationship showed no significant trends between the years for either sex. There was also no correlation between the ML_TW and total squid catch or temperature. A white caecum occurred significantly more often in males than in females (dof = 1; p < 0.05) from General Linear Model (GLM), indicating that the presence of non-feeding males in the spawning grounds may be linked to the behaviour of spawning squid.

  • Description: A mass balance study was conducted comparing inflowing and outflowing solute loads in order to calculate the treatment efficiency of a free water surface (FWS) constructed wetland used to treat domestic wastewater following primary treatment in an anaerobic reactor and oxidation in a rotating biological contractor. Water samples were taken at six locations down the length of the treatment system and analysed for nitrate nitrogen (NO3-N), nitrite nitrogen (NO2-N), ammonia nitrogen (NH4-N) and phosphorus as phosphate (PO4-P). Flow was determined using two V notch weirs combined with pressure transducers based on an empirically derived stage-discharge relationship. The concentration of each solute (g.m-3) multiplied by flow (m3.day-1) provides a measurement of the mass of each solute entering and leaving the treatment wetland such that the difference (inflow – outflow) indicates the nett storage in, or loss from, the wetland. In order to determine the water balance, apart from measuring surface inflows and outflows, rainfall was measured using an onsite rain gauge. Evapotranspirational losses were determined using the Penman-Monteith equation based on weather data collected at an onsite weather station. Other than water that entered the wetland via the primary water treatment works, surface inflows could be ignored as the wetland was sealed with a plastic liner, which also prevented groundwater inflow and outflow. Wetland outputs via surface outflow and evapotranspiration were then subtracted from wetland inputs to determine the water balance over the study period. Approximately 10.5% of water inputs into the hydrological mass balance calculation was not accounted for, which is considered to be accounted for by inaccuracy associated with the estimation of evapotranspiration and possibly by differences in water levels in the wetland at the start and end of the experiment. Total input, output and storage of NO3-N, NO2-N, NH4-N and PO4-P was calculated from April 2016 to September 2016 to give the treatment efficiency of the FWS wetland system. Results showed a 91.5% reduction in NO3-N, 76.6% reduction in NH4-N, and 88.8% reduction in PO4P between the inflow and outflow. Wetland sediment and vegetation (Typha capensis) samples were also analysed for nitrogen and phosphorus content to give an estimate of nutrient stocks/storage accumulated in plant tissues and sediments over the lifespan of the wetland. Standing stock calculations showed that a total of 450.1kg of nitrogen is stored in the wetlands, of which 69.3kg is stored in wetland sediments. Wetland phosphorus retention was found to be significantly lower with a total of 57.1kg of phosphorus, of which 77.4% was stored in sediments, indicating that wetland sediments comprise the largest store and therefore removal pathway of nutrients in the Crossways Farm Village FWS wetland.

  • Description: Background:The complex nature of healthcare systemsoftenresultsinthe emergence of context-specific barriers that limit the ability for healthcare stakeholders to ensure safe and effective care delivery. In low-to middle-income (LMIC) countries, such as South Africa (SA), limited financial, material and human resources coupled withpoor infrastructure and poor public health determinants, includingpoverty andpoor education, affectthe ability to maintain andimprove on quality care outcomes.Understanding what different stakeholders perceive as barriers, and if these barriers are understood at different levels, is therefore important when attempting to mitigate the risk for unsafe or inefficient care delivery. Human Factors and Ergonomics (HFE) adoptssystems and participatory approaches for the exploration, analysis, and design of socio-technical systems to optimize both human wellbeing and system performance.The barriers to safe and effective healthcare delivery, from an HFE perspective, are not known in the South African context, particularly in parts of the Eastern Cape Province. Elucidatingthesebarriers, even if self-reported,may guidefuture efforts aimed at mitigating risks.The purpose of this study, therefore,wasto explore and highlight the perceived systemic barriers to local and national healthcare delivery, within the Sarah Baartman District in the Eastern Cape Province of South Africa.Methods: Ashort discussion aimed at introducing HFE and components of the Work Systems Model, followed by a survey that captured participant demographics, job characteristics, the perceived national and local systemic barriers, and proposed solutions, was administered withhealthcare stakeholders from 14 primary healthcare facilities and 1 department office within the Sarah Baartman District.Participants (n=120) included management, pharmacy, administration, maintenance, community-and home-based care and nursing staff.Data from the surveys were thematically analysed and categorised according to components of the work system model (Carayon, 2009) and respective workgroup.Results: The findings revealed many overlapping,systemic barriersthat includedshortages of staff, poor management and leadership, a lack of equipmentand basic necessities, poor infrastructure, patient complexity,and high workloads. The results further indicate that the way in which the reported barriers affect worksystem interactionsand performance are unique to different workgroups. Stakeholders iiproposedthat,among others, the absorption of contract workers, the provision of training and adequate human and medical resources and the maintenance of facilities may mitigate the barriers and improve healthcare delivery.Conclusion: The findings highlight a myriad of perceived systemic barriers perceived in the Sarah Baartman district, some of which were fundamental for the effective function of any healthcare system. These barriers may have wide-spread implications for stakeholders at all levels, ultimately affecting the performance, satisfaction and safety and the quality of care. It is especially important to consider these barriers in light of the COVID-19 epidemic, which emerged throughout this study and the major threat it presents to South African healthcare systems. Future research should aim to explore how these barriers interact to contribute to processes and outcomes, as well as explore the perceptions at provincial and national levels in order to better identify areas and strategies for improvement.
