- Description: This treatise considers the implications of the judgment in Minister of Justice and Constitutional Development v Prince (2018) ZACC 30 in the workplace. It includes a critical study of cases prior and post the judgment and identifies the gaps within those judgments. It will consider various legislation pertaining to the topic and the critical differences when it comes to testing for intoxication of alcohol versus cannabis. To conclude, it will consider the challenges of having a zero-tolerance policy in the workplace and provide recommendations to employer’s substance abuse policies specifically relating to the use of cannabis and its effects within the workplace.

- Description: Background. Evidence from high-income countries suggests that childhood trauma is associated with schizophrenia. Studies of childhood trauma and schizophrenia in low and middle income (LMIC) countries are limited. This study examined the prevalence of childhood traumatic experiences among cases and controls and the relationship between specific and cumulative childhood traumatic experiences and schizophrenia in a sample in South Africa. Methods. Data were from the Genomics of Schizophrenia in the South African Xhosa people study. Cases with schizophrenia and matched controls were recruited from provincial hospitals and clinics in the Western and Eastern Cape regions in South Africa. Childhood traumatic experiences were measured using the Childhood Trauma Questionnaire (CTQ). Adjusted logistic regression models estimated associations between individual and cumulative childhood traumatic experiences and schizophrenia. Results. Traumatic experiences were more prevalent among cases than controls. The odds of schizophrenia were 2.44 times higher among those who experienced any trauma than those who reported no traumatic experiences (95% CI 1.77–3.37). The odds of schizophrenia were elevated among those who experienced physical/emotional abuse (OR 1.59, CI 1.28–1.97), neglect (OR 1.39, CI 1.16–1.68), and sexual abuse (OR 1.22, CI 1.03–1.45) compared to those who did not. Cumulative physical/emotional abuse and neglect experiences increased the odds of schizophrenia as a dose–response relationship. Conclusion. Childhood trauma is common in this population. Among many other benefits, interventions to prevent childhood trauma may contribute to a decreasing occurrence of schizophrenia.

The relationship between economic growth and electricity consumption in South Africa

- Description: In recent years, the relationship between electricity consumption and economic growth has been examined extensively in numerous countries. While there is high consensus in the scientific sphere on the interdependence between electricity consumption and economic growth, recent literature suggests that there are still competing views on the causal relationship between the two variables. Energy has long been viewed as a vital driving force for economies. However, the crucial role that the energy sector has played during the industrial revolution allowed some authors to consider energy in the same way as the capital and labor factors in the production function. The energy factor is considered essential today in the process of development. Almost everyone agrees on the importance of its contribution to the process of growth and development by considering growth / energy model as an indicator of wealth and a vector to reduce social inequalities. Meanwhile, according to the different scenarios observed, energy consumption may or may not have impacts on economic growth or wealth creation. The problem of access to energy (electricity) in certain regions in Africa (and particularly in South Africa) remains one of the major challenges that require urgent attention over the coming decades. In addition, the lack of consensus among researchers has triggered a shift towards focusing on study methods and techniques used for investigations on the energy-growth nexus. Using R programming for data analysis, this study investigates the asymmetric relationship between energy consumption and economic growth in South Africa by incorporating the following intermediary variables: trade openness, capital and labour. Results suggest that a conservation hypothesis is the most prevailing theory on the causal link between GDP and Energy Consumption in South Africa. This opinion is acknowledged as the growth-led electricity consumption opinion. From an economic perspective, evidence from the research suggests that, without necessarily expanding energy accessibility, trade liberalisation and capital could generate clear gains to South Africa and efforts to promote and accelerate these initiatives should be encouraged. Given the often-competing resource limitation challenges faced by the South African government, as a result of prioritisation, trade liberalisation should be favoured and be given roughly in the range of 1.5 times more attention than capital. Therefore, South Africa may not necessarily need electricity for its economic growth. Although energy consumption has a major influence on economic growth, the latter could also possibly be achieved by increasing trade and/or capital, without any change in energy consumption. Energy conservation policies could be executed with little or no hostile effects on economic growth. As a policy intervention, the research study recommends sustained efforts to strengthen regional integration with the view to achieving trade liberalisation, increasing capital formation and creating greater synergy for economic growth.

- Description: Employee wellness and work engagement have a positive influence on organisational behaviour. The main aim of the research study was to understand whether a relationship existed between employee wellness and work engagement in a Non-Governmental organisation (NGO). The research used a cross-sectional design and a composite questionnaire to measure employee wellness and work engagement. This was a paper and pen-based questionnaire which was distributed to 160 employees. Of the 160 questionnaires distributed only 155 participants responded. These participants are employed at NGO’s based in Port Elizabeth, Johannesburg and East London. An exploratory factor analysis determined a new more reliable factor structure for PWS. Employee wellness lost items and became a three-factor structure. The results showed that the new EFA model was best suited for the present study. Work Engagement remained a three-factor structure. T-tests and ANOVAs revealed significant differences between the constructs and the demographic groups. Correlations showed the main findings of the study to be a relationship between employee wellness and work engagement in a non-governmental organisation.

- Description: Export diversification on economic growth has been a controversial issue in the empirical literature for a long time. This study examined the role of export diversification and export concentration on economic growth in the top ten trading countries in Africa and top ten trading countries in the world. The study used annual time series data for the period covering 1995 to 2014 and employed a PMG (Pooled Mean Group) Model to determine the effects of export concentration and export diversification and possible factors that affect it on economic growth. The estimation results attest to a positive effect of export diversification and a negative effect of export concentration on economic growth in the top ten trading countries in the world. However, for the top ten trading countries in Africa, the results show that export diversification is negatively related to economic growth, while export concentration positively affects economic growth. These results hold even when the DOLS and FMOLS are employed establishing their robustness. The study further shows that other control variables such as employment and government spending positively affect economic growth, while human capital and investment negatively affects economic growth in Africa. In the top ten trading countries in the World, government expenditure and investment are significant positive determinants of economic growth. It is recommended that governments in Africa countries should promote export diversification together with government expenditure, and pursue policies that will attract foreign direct investment into growth–enhancing productive sectors of their economies

The study assessed whether theoretical and empirical propositions can be supported in South Africa. Co-integration tests utilising ARDL bounds testing method were employed to examine if there is a relationship between the variables of interest. As a proxy of financial sector development, stock market capitalisation and bank credit to the private sector were employed. Other variables that affect financial development such as money supply, interest rates, Gross Domestic Product, trade openness and net interest margin were also included in the model. The results of the study indicate that there exists a negative relationship between inflation and stock market capitalisation. Bank credit to the private sector showed a positive relationship with inflation both in the short run and long run.

- Description: The primary objective of this study was to investigate whether relationships exist between workplace trust, work engagement and turnover intentions. Moreover, it also investigated the significant demographical differences of the constructs. This study is of a positive psychology paradigm and primarily non-experimental cross-sectional and correlational in nature. The participants were from the workforce of a large manufacturing organisation (n=568) within the Eastern Cape. A non-probability convenience sampling method was used. Data was collected through the aid of self-administered standardised paper-and-pencil questionnaires, which incorporated the Workplace Trust Survey, the Utrecht Work Engagement Scale and the Turnover Intentions Scale. Only instruments that showed construct validity and reliability were used. The necessary steps were taken to ensure that plagiarism, bias, data manipulation and physical and/or emotional harm was avoided, whereas confidentiality and anonymity were maintained. Only 140 questionnaires were returned, from which only 104 were fully completed. Data analysis and interpretation were performed with the aid of descriptive and inferential statistical analysis methods. Pearson’s product-moment correlations were used to determine statistically significant relationships between the constructs. The analysis of variance (ANOVA) and Tukey’s post-hoc tests were used to determine significant demographical differences between the constructs. It was found that all three measuring instruments had Cronbach’s alpha scores above 0.80, indicating good internal reliability and validity. The findings of the study identified a number of correlations between the constructs and their factors. It was found that a positive relationship exists between workplace trust and work engagement, as well as between the factors of both these constructs. A negative relationship was found between turnover intentions and both workplace trust and work engagement and their respective factors. Significant demographical differences were found for gender on the workplace trust scale, and two of its factors (trust in the organisation and in the immediate manager), and vigour. In addition to this, significant demographical differences were found for race on the workplace trust scale and two of its factors, namely trust in the organisation and in the immediate manager. This research study’s findings made a valuable contribution to the field of workplace trust, work engagement, turnover intentions and the manufacturing environment. The results of this study hold important implications for the organisation in question and provide a platform for future research studies. This study aids in better understanding the relationships between the constructs and their variables, to formulate better retention and enhancement strategies.

- Description: The problem that this study is grappling with is that since the SACC has followed the Critical Solidarity model it is less successful in meeting its goals, to support human welfare and ecumenical solidarity in South Africa. The research will compare the two respective models of relations between SACC and State, that which guided the SACC after the demise of Apartheid that which guided it. First, the research will investigate why the present relationship of Critical Solidarity has proven less effective in achieving its goals. Secondly it will investigate factors accounting for the relative success of the model of relations between SACC and the South African State during the struggle against apartheid, that of Liberation Theology. Secondly, this study will recommend the reconstruction of a more effective model of Critical Solidarity, to remedy present weaknesses, by incorporating factors from the apartheid-era model of Liberation Theology that which serve the goals of ecumenical solidarity and human welfare. The research seeks to address the following questions. What challenges, for the goals of the SACC, of ecumenical solidarity and human welfare, have arisen for the SACC that may be attributed to its adoption of a model of Critical Solidarity in its relationship with the State? What factors conducive to ecumenical solidarity and human welfare are absent from the present model of Critical Solidarity, though they present the preceding model of relations between Church and State as adopted adopted by the SACC during the struggle against apartheid, modeled on Liberation Theology? How might these factors conducive to Church unity and social justice in South Africa be reintroduced in the present model of Critical Solidarity

- Description: This dissertation explored the views of academics who teach and research in the area of Industrial/Organisational Psychology in South Africa about the utility of the field in engaging with the post-1994 South African workplace, thereby remaining relevant. When it emerged as a field of study and practice, Industrial/Organisational Psychology research’s aim was to inform workplace practice and contribute to the betterment of society. It appears as if today this research is deemed irrelevant to the workplace and society, with many practitioners relying on their own knowledge and irrelevant repetitive one size-fit-all Euro-American developed theoretical framework and research evidence to solve the challenges of the post-1994 South African workplace, and to serve its society. The latter propelled the researcher to ask broadly the question of relevancy of the discipline in meeting the demands of the post-1994 South African workplace. Face-to-face, semi-structured interviews were employed to collect data on 8 senior and younger generations of academics in 3 different universities. The collected data was analysed using Braun and Clarke’s 6 steps of thematic analysis. The data and study as a whole was approached with a ‘post’-colonial lens and a Contexualist paradigm in order to contextualise in the present time the past nuances that arose in our country during the colonial and apartheid eras. Themes discussed seemed to indicate a lack of research focus by academics and their students due to limited time and stringent bureaucratic publication structures present both within their universities and outside. When it came to the discipline as seen through the lens of the data and what this suggested in terms of speaking to post-1994 workplace organisational psychological problems, the study found that the findings arising out of the research in I/O psychology appear to be of little relevance to whom they are currently aimed, leading to the idea of these studies acting as a change agent in the workplace and society to fall to the wayside.

- Description: Universities have long been characterised by hierarchical and paternalistic management structures and institutional cultures. Change is therefore to be welcomed but, in contexts where social change is urgently needed, it is possible to mistake a change in any direction as being worthwhile. Around the world, recent shifts in university leadership and management have been towards managerialist approaches that work against a shared responsibility for the academic project. Accusations of managerialism often refer to a general sense that institutions are becoming bureaucratic, or that it is the logic of the market that drives decision-making. But beyond vague complaints, these accusations fail to identify the exact processes whereby managerialism takes hold of the institution. This article hones in on one specific example of institutional change in order to argue that it is implicated in the move towards managerialism: most universities in South Africa have changed from having elected deans, selected by faculty, to executive deans, appointed by selection committee. Crudely distinguished, it can be said that elected deans represent the interests of their faculty up into various institutional structures whereas executive deans are tasked with implementing the decisions of top management down into faculty. This paper tracks the differences between the two forms of deanship through reflections on discussions about such a change at one South African institution, Rhodes University. It analyses the literature to argue that we do not have to choose between patriarchal management and compliance-based managerialism. Instead, we can choose shared responsibility for the academic project.

- Description: Academic developers are tasked with supporting institutions in times of change. Essential for preparing academic developers for professional practice is enabling them to engage with and integrate existing knowledge with new knowledge, and apply their understandings to new contexts. Focusing on the summative assessment processes and products of a course specifically for academic developers, this chapter shows how cumulative knowledge-building can be achieved in both course design and pedagogy. Drawing on LCT concepts of ‘semantic gravity’ and ‘semantic density’, two high-achieving portfolios were analysed. The analysis indicates that movements between knowledge that is relatively abstract, decontextualized and complex to knowledge that is relatively concrete, context-dependent and simpler, represents a key characteristic of cumulative learning for professional practice courses. The chapter demonstrates how LCT can reveal the tacit ‘rules’ for success in the course, as well as how pedagogic strategies can be designed to achieve the desired outcome.

- Description: It has been a historical norm in African societies for children to leave in the homes of caregivers. Among these caregivers are the grandparents, who are from time immemorial, being a pillar of support to their children in caring for their grandchildren. Against this background, the study assesses custodial the role of grandparents in the psychosocial well-being of adolescent children from single parents' homes in Buffalo City Metropolitan Municipality, Eastern Cape Province, South Africa. The study was guided theoretically by Role and Ryff's psychosocial well-being theories. Four sets of participants totaling 323 gathered using a mixed-method approach comprised of 150 adolescents and 136 custodial grandparents through questionnaires, 30 single parents, through in-depth interviews, and seven social workers through focus group discussions. The study utilized a multi-stage sampling technique to select adolescents and their grandparents, a purposive sampling technique for single parents, and a convenient sampling technique for social workers. The quantitative data were analyzed using descriptive statistics and Pearson's Correlation Coefficient, while the qualitative data were categorized manually into themes and subthemes. Findings indicated a correlation between the attainment of the adolescent children's psychosocial well-being and the effectiveness of the custodial grandparents' role. More also, the challenges encountered by custodial grandparents do affect the attainment of the psychosocial well-being of adolescent children. Furthermore, finding from the study revealed that non-governmental organizations in the municipality were not rendering social support for the custodial grandparents. Finally, the child-support grant received by poor grandparents is grossly inadequate to meet up with the astronomical needs of the adolescent children. The study concluded that custodial grandparents' social support is an effective mechanism in meeting adolescent children's psychosocial well-being. Several recommendations were made from the conclusions to various stakeholders and proposed a responsive conceptual grand-parenting model to cater for effective parenting.

- Description: Elephants were successfully reintroduced into the 900 km2 fenced Hluhluwe-iMfolozi Park (HiP) from 1981 onwards and their population has increased exponentially since. Their initial reintroduction was motivated by the need to control bush encroachment and to maintain ecosystems such as grassland and open woodland, and to restore ecological processes offered by elephants. The subject of the HiP elephant population and their impact on vegetation in the Park has become controversial; with some concerns being raised that the population is too high and is negatively affecting the vegetation. An absence of a vegetation monitoring programme in protected areas with elephants creates uncertainty leading to an ‗elephant impact‘ debate. This study aimed to compare the perceptions of stakeholders regarding the issue of elephant impact in HiP with measured elephant impact on the vegetation in the Park. The perceptions and concerns of stakeholders regarding the effects of elephants on vegetation in HiP were investigated using a questionnaire. Stakeholders reported that elephants and fire were the main factors shaping vegetation change in HiP over the past decade. Sclerocarya birrea, Senegalia burkei and Schotia brachypetala were reported as the most negatively affected species. Also reported that they are concerned about the effects of elephants on the number of tall trees in the park, tree mortality and elephant‘s effect on rare indigenous vegetation. Most interestingly, the results showed that the groups of stakeholders had different perceptions of the level of elephant impact on the vegetation in the park; except for researchers and tourists whose were not significantly different from each other. Managers had the most respondents that reported that the level of elephant impact is unacceptable, while most researchers and tourists reported that the level of elephant impact is at an acceptable level. Vegetation plots that had been surveyed in 1999, 2003 and 2007, were resurveyed in this study during 2017 to assess elephant impact on vegetation over time. Comparison between the years sampled showed that there was a decrease in the density of tall trees, while the density of trees in 0.5-2 and 2-4 m height classes increased over the same period. Elephants had a strong preference for utilizing tall trees (>4 m) and a strong avoidance for trees in the height range from 0.5-2m tall (Jacobs selection index 0.56 and -0.69, respectively). This trend was apparent for all sample periods. In addition, elephants also showed a strong preference for some rare species including S. brachypetala and Sideroxylon inerme. Between 1999 and 2017, the density of preferred species has decreased while the density of avoided species has increased. I conclude that elephants are having a noticeable impact on the vegetation at HiP by changing vegetation structure to a shrub dominated vegetation, and causing a shift in species composition towards avoided species. The findings of this study show that the perceptions of stakeholders on the effects of elephants and the level of elephant impact on vegetation match the results from measured elephant impact - vegetation survey. However, Thresholds of Potential Concern (TPCs) should be outlined in the elephant management plan and are required to determine whether the levels of elephant impact at HiP have exceeded an acceptable level or not. This study conforms to previous research that an uncontrolled elephant population can have substantial impacts in fenced reserves. This study shows the importance for long-term and continuous vegetation monitoring programme to obtain reliable data to determine trends in vegetation changes over time.

- Description: Environmental sustainability and agriculture are key development and transformational concerns in South Africa while rural development and youth unemployment are key national issues pertinent in the Eastern Cape which ranks in the top three provinces for both concerns. As a formative interventionist researcher, working in a singular case study with youth in Lenye village located in the Eastern Cape Province of South Africa, I sought to investigate the following: Can, and if so, how can expansive learning facilitated by a change laboratory intervention contribute to the development of youth as potential value creators for rural development? This was investigated through the following sub questions: 1) What value is created at each point of the expansive learning process of the change laboratory process and for who? 2) What value can still be created at each point of the expansive learning process of the change laboratory? 3) How is that value created via an expansive learning process? I collected data as I participated as a youth member through: extended contextual profiling via a focus group interview, individual interviews, note taking and document analysis. Furthermore, I attended village meetings, youth meetings and emergent youth development/youth in agriculture/agriculture opportunities. Additionally, change laboratory workshops were conducted and I used audio recordings and notes to capture data. The data collected was then analysed through second generation Cultural Historical Activity Theory using the concepts of immediate, potential, applied, realised and reframing value. In conclusion, the expansive learning process may contribute to the development of rural youth as value creators for sustainable development through youth development, agriculture and community development. All forms of value were created along the expansive learning process for the formative interventionist researcher, the Lenye youth and the greater Lenye youth community. All forms of value may still be created for the Lenye youth, the formative interventionist researcher and the greater Lenye youth community.

- Description: This research was a Case Study on the role of Flexible Working in achieving a Work – Life Balance, based on the Information Technology Consultants of Kestrel Business Solutions – a company based in London, the United Kingdom. The study set out to determine what aspects of flexible working can reduce work - related stress; home - related stress; improve personal wellbeing; identify the pitfalls of flexible working, and to recommend mitigating actions. The literature review identified five different, but complimentary theories that included: The Spill over Theory; Balanced Theory; Resource Based Theory; Compensation Theory and the Wellness Theory to unpack and explore the concept of Work - Life Balance. The study followed a predominantly qualitative methodology approach and used thematic analysis to identify key ideas from the data. Interviews and questionnaires were used to obtain data from the respondents, in addition to being a data triangulation exercise. From a population of 10 subjects - purposeful sampling was used to select a sample of 10 respondents - made up of 3 males and 7 females. All respondents were employees of Kestrel Business Solutions. 6 respondents were interviewed and given questionnaires to fill out. 6 face to face interviews were conducted, and 6 questionnaires completed until saturation was achieved - indicating a survey response rate of 100%. The results from the data collection generally showed how aspects of flexible working like telecommuting, flexitime and homeworking ultimately helped the employees to achieve a Work-Life Balance - by primarily influencing how they balanced their work, home, and personal commitments. Importantly, the study also identified pitfalls of flexible working; like employees feeling isolated and the pressure to perform. Potential mitigating efforts identified in the study included, providing more company support and education for flexible working initiatives. The study concluded by acknowledging the limitations of the study, which included time constraints and the small population, and sample size of the study. In its conclusion, the study identified recommendations for future studies like: increasing the population and sample size, and devoting more time to the study, for more generalized and conclusive findings.

- Description: Molecular chaperones regulate cellular proteostasis. They control protein conformation and prevent misfolding and aggregation under both normal and stressful environments, ultimately resulting in cell survival. The project aimed to understand the role of the HSP70 – HSP90 Organizing Protein (Hop/STIP1) in the survival of stressed cells and the function of the stress-responsive transcription factor, Heat Shock Factor 1 (HSF1). HSF1 protein levels were significantly reduced in Hop-depleted HEK293T cells compared to controls by ELISA, western blot, and mass spectrometry. HSF1 transcriptional activity at the HSP70 promoter, and binding of a biotinylated HSE oligonucleotide under basal conditions were significantly reduced, consistent with the reduced levels of HSF1. In response to heat shock, HSF1 levels in Hop-depleted cells increased to that of controls, but there was still significantly lowerHSF1 transcriptional activity and HSE binding. Hop-depleted HEK293T cells were more sensitive than controls to the HSF1 inhibitor KRIBB11 and showed reduced short-term and long-term proliferation. Unlike the HSP90 inhibitor 17-DMAG, which had no effect, the HSP70 inhibitor JG98, further decreased the levels of HSF1 in Hop-depleted cells, suggesting a role for HSP70 in the Hop-mediated effects. There was punctate nuclear staining for HSF1 in Hop-depleted cells under both basal and heat shock conditions, as well as reduced nuclear localization and increased cytoplasmic accumulation of HSF1 in response to heat shock. Hop and HSF1 colocalized in cells, and HSF1 could be isolated in complex with Hop and HSP70. Loss of Hop reduced HSF1 in HSP70complexes but did not affect HSF1 abundance in HSP90 complexes. Hop-depleted cells showed reduced short-term and long-term survival compared to controls, an effect that was potentiated by the JG98 HSP70 inhibitor. Taken together, these data suggest that Hop regulation of HSF1activity is via a mechanism involving reductions in HSP70 interaction, as well as reduced nuclear localization, and DNA binding, and is consistent with reduced cellular fitness under basal and stress conditions. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2020

- Description: Innovation has emerged as an important factor for the survival of businesses especially when there are external factors at play such as increased competition, economic decline and demanding consumers. Organisations need to innovate to remain attractive in the global economy. To be able to address the needs of customers in a quick way, organisations need to be cognizant of the social and technological shifts so they can be in position to exploit them to their advantage. In today’s competitive environment, innovation is a driver of change and organisations that resist that change are in danger. Regardless of the scope of the resource pool and the organisational excellence, companies cannot shield themselves from change. While change comes with risk and uncertainty, it also presents opportunity. The choice to innovate must be supported by actions that foster an environment in which people are comfortable to be innovative. An organisational climate that inspires members to engage in innovation is vital for the innovation efforts of an organisation to be successful. The purpose of the study was to determine the leadership practices that can be adopted to build and sustain a` work environment that fosters innovation. To achieve this objective a conceptual model was constructed from literature and the relationship between six constructs was tested, namely, organisational culture, leadership style, leadership behaviour, reward and recognition, training and development, and a climate for innovation. To test the conceptual model, a questionnaire was sent to 82 participants working in the media and entertainment industry. The results of the data analysis highlighted that the organisational culture and the leadership behaviour have a significant positive relationship with the climate for innovation. Positive changes in the organisational culture and leadership behaviour are likely to lead to a more conducive organisational climate for innovation.

- Description: Microhabitats provided through structural complexity are central for the diversity, productivity, connectivity and niche differentiation within and among ecosystems. Mangrove forests afford juvenile fish and invertebrates with nursery and recruitment habitats, facilitated by the fine scale configuration of their specialised root systems. Although the importance of mangroves for resident and transient juveniles is well recognised, the roles that mangrove microhabitats play for larvae is not yet comprehensively understood. This study aimed to determine how microhabitats with varying degrees of complexity influence the composition, abundance and distribution of larval communities that inhabit mangrove forests and the physiological responses of larvae to acute temperature variations in relation to ontogenetic stage and microenvironment exposure. Two relatively pristine study sites were selected to represent a warm temperate and subtropical mangrove system in the Eastern Cape and KwaZulu-Natal on the east coast of South Africa, respectively. The differences in complexity among the root systems of Rhizophora mucronata, Avicennia marina and Bruguiera gymnorhiza were assessed using 3D scanning and the computed 3D models were then analysed using four complexity metrics. Results indicated that A. marina is the most complex in terms of surface-volume ratio, R. mucronata has the most interstitial space among its roots and B. gymnorhiza and R. mucronata differ in their fractal dimensions. Larvae collected in each microhabitat at each site using light traps showed that, despite temperature and salinity homogeneity across microenvironments, spatio-temporal differences occurred in both fish and invertebrate assemblages. This trend suggests that microhabitat structural complexity exerts an influence on larval community composition by acting as a microscape of available habitat, which ensures ecological linkages within and among the mangrove forest and adjacent ecosystems. In addition, the oxygen consumption rates of mangrove-associated brachyuran larvae varied according to mangrove microhabitat, whereby larvae collected at less complex environments had the highest metabolic rates at increased temperatures. Moreover, ontogenetic shifts in physiology were prevalent as older brachyuran larvae were more eurythermal than earlier stages, suggesting that thermally stressful events will have a greater impact on recently spawned larvae. Overall, the interstitial spaces within individual root systems are the most important complexity measure, as utilisation of these mangrove microhabitats is scale-dependent, and larvae will most likely occupy spaces inaccessible to large predators. Likewise, microscale variation in the environmental conditions and ontogenetic stage of brachyuran larvae within the mangrove microscape, can amplify the physiological responses to rapid temperature variations. Results suggest that early stage larvae are the most vulnerable to mass-mortality, and if thermally stressful events increase in frequency, duration and magnitude, the larval supply for the successful recruitment into adult populations could be under threat. Through linking how mangrove microhabitat complexity influences larvae in terms of community metrics and physiology, this study paves the way for further advancement of our understanding of how microscale processes emerge into meso- and macroscale patterns and influence the stability and functioning of highly productive ecosystems.

- Description: This study intended to investigate the relationship between the NW striking structures and the high-grade ore shoots at the Syama gold mine in Mali, West Africa. All structural data collected since 1987 from drill core have been integrated to allow the interpretation and modelling of these NW-SE structures. The structures collected were grouped into three main groups; foliations/shears/faults, veins and joints/contacts/fractures. Micromine software was used to plot the structures, printed out on A3 paper and interpreted manually using tracing paper. Analysis and interpretation of stereographic plots has shown that the majority of the high-grade zones are generally located at the intersection of the NNE structures and the NW structures. The observed cross-cutting relationship between the NNE and the NW structures suggests two different generation of faults. It is suggested that the NW structures were active during the D4 deformation event (Standing, 2007) and have played a role in reactivating earlier (D3) NNE structures, allowing greater fluid flow and enhancing the gold grade. These zones are mainly defined by brecciation and stockwork veining. The E-W structures are believed to be the latest and are attributed to the D5 event. Although gold mineralisation is grossly controlled by the NNE structures, the NW structures need to be considered as major gold enrichment upgrading factors at Syama. It is therefore strongly recommended that ongoing exploration at Syama specifically target the intersection of the NW and NNE structures as favourable zones for high-grade mineralisation.

- Description: This study examines the role of primary schools in promoting democratic values of justice, equality and liberty in pupils in Shamva District, Zimbabwe. The study was necessitated by the continual abuse of democratic values by school leavers in the district before, during and after elections. Such continued abuses make one wonder if schools really inculcate democratic values of justice, equality and liberty in their pupilsas enshrined in the curriculum. Using a qualitative approach, the study is located within the interpretivist research paradigm. A case study design was adopted and three primary schools in Shamva District were purposively and conveniently selected for this study. The sample comprised three 3 primary schools heads, three 3 deputy heads, nine 9 teachers, five 5 school leavers and fifteen 15 prefects aged between 10 and 15 years old. Data was generated through semi-structured face-to-face interviews, focus group interviews and document analysis. The findings of the study revealed that schools had challenges in inculcating democratic values of justice, equality and liberty in learners. The challenges included difficulties in interpreting the syllabi on inculcation of democratic values of justice, equality and liberty in learners; democratic values being viewed as sensitive content usually misconstrued to be favouring certain political agendas by community members; and the lack of a clear cut democratic values curriculum framework to guide teachers on teaching democratic values of justice, equality and liberty. Some of the recommendations were that teachers should be protected by legal instruments like policies to enable them to freely teach sensitive content. Teachers also need empowerment in syllabus interpretation on the inculcation of democratic values to be able to effectively promote the teaching of democratic values of justice, equality and liberty. , Thesis (PhD) -- Faculty of Education, 2020
