- 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.

The role of elephants in Hluhluwe-iMfolozi Park: Perceived versus measured effects on woody vegetation

- 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: 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.

- 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

- Description: Small-scale fisheries depend on the ocean as a source of social and economic benefit for the world’s population, especially in developing countries. Coastal communities face challenges in ensuring that fisheries are sustainable and resilient to the effects of climate change. The collapse of small-scale squid fisheries in South Africa in 2013-2014 raised concerns in South Africa’s fishing industry, leading to various studies that focused on the marine environment. Small-scale fisheries are important in terms of their contribution to various national economies, job creation for coastal communities and the sustainability of human existence. Society needs a detailed knowledge of the living components of natural and managed systems, as global climate changes affect the functions of ecosystems and consequently the well-being of humans. A qualitative research approach using unstructured interviews with participants was appropriate for this study. This approach gave an opportunity for participants to explain their views and provide an in-depth understanding of their social phenomena. The significance of this study is that it broadens knowledge and understanding of how small-scale fishers respond and become resilient to climate change, shocks and other risks that affect social and ecological systems negatively and assists in forecasting the likelihood of a future collapse of the fishing industry. The study’s results indicate that squid fishers’ local knowledge supports the view that there are changes in the squid stocks, with fishers detailing the changing weather patterns and climatic conditions. The squid fishers identified unsustainable fishing practices that damage the spawning areas as a problem area. There was a general concern amongst the limited number of interviewees that the future of their livelihood was in peril and changes had to be made. Local knowledge and the perceived desire to care for the environment are important for managing squid resources and fostering communities’ resilience to climate change.

- Description: This study concentrated on the role of development funding to promote Local Economic Development (LED) in the Sarah Baartman District (SBD). Although the research discussed the funding institutions available for Small-, Medium- and Micro- Enterprises (SMMEs) in general, the main focus of this study was the Local and Regional Economic Development (LRED) Grant Fund, which is solely established to support SMMEs in the Eastern Cape. A qualitative study was undertaken in the SBD that targeted two semi-rural municipalities in the Karoo. The Dr Beyers Naude and Koukamma Local Municipalities were targeted for this research. Both municipalities are semi-rural and located in the Karoo. The study found that in order to realise sustainable economic growth, LED must be encouraged and supported within the local space. The literature review encouraged the employment of participatory development as well as addressing issues of social structures as they reinforce limitations on growth and exposure. The District Development Model (DDM) highlights the coordination of Government programmes to a district. The model also significantly devolves Government functions and structures for integrated planning and implementation to district and metropolitan municipalities. Local government is viewed as the lowest sphere of Government, and is responsible for delivering basic services and the governance of local municipalities. This level of Government also places the performance, monitoring, evaluation, and reporting (PMER) of governance at a district level. Such PMER could enable a district to have first-hand performance reports regarding development in relevant jurisdictions. In attempting to address the problem of unemployment, poverty, and economic growth, the Department of Economic Development, Environmental Affairs and Tourism (DEDEAT) established the LRED Grant Fund, which is solely meant to assist SMMEs in the Eastern Cape. This fund is tailored to aid the initiatives and/or businesses in the following sectors: agro-processing, automotive, manufacturing, renewable energy, oceans economy, and tourism. However, there is a current concern regarding the LRED’s lack of transparency, communication, and uncertain turnaround time during application assessment and adjudication processes.

- Description: Unemployment is a global threat and has been identified as a crucial factor affecting South Africa s economy. Unemployment rate is one of the key indicators of South Africa s economy and reports by Statistics South Africa have indicated an increase in the unemployment rate. Studies done by the International Labour Organisation (ILO) has ranked South Africa amongst the worst in the world for unemployment and that poverty manifests not as a financial indicator but as a result of lack of employment opportunities. In response to the challenge of unemployment, South Africa has introduced numerous policies and strategies to combat unemployment and alleviate poverty. The vision of the Expanded Public Works Programme (EPWP) is to assist South Africa with its challenge of poverty eradication and to ease the unemployment statistics while simultaneously promoting skills development for its participants and the main focus of this policy is to provide income relief for the unemployment. The aim of this research was to assess the impact of EPWP in alleviating unemployment in Grahamstown, by assessing whether or not the EPWP has had any significant influence on job creation and skills development. This study focused on programmes implemented during the period 2014-2017 which is under phase 3 of the EPWP. This study adopted a qualitative research method and followed a descriptive approach. The research method did not seek to prove a true cause-effect relationship between the variables but rather demonstrate the correlation by means of case studies, archival research and content analysis. The research results revealed the potential of the EPWP projects in job creation in the area, and that there are areas of development and challenges in order to achieve the overall purpose of the EPWP.

The vision of the Expanded Public Works Programme (EPWP) is to assist South Africa with its challenge of poverty eradication and to ease the unemployment statistics while simultaneously promoting skills development for its participants and the main focus of this policy is to provide income relief for the unemployment. The aim of this research was to assess the impact of EPWP in alleviating unemployment in Grahamstown, by assessing whether or not the EPWP has had any significant influence on job creation and skills development. This study focused on programmes implemented during the period 2014-2017 which is under phase 3 of the EPWP. This study adopted a qualitative research method and followed a descriptive approach. The research method did not seek to prove a true cause-effect relationship between the variables but rather demonstrate the correlation by means of case studies, archival research and content analysis. The research results revealed the potential of the EPWP projects in job creation in the area, and that there are areas of development and challenges in order to achieve the overall purpose of the EPWP.

- Description: We evaluated the impact of the gall-forming mite, Aceria lantanae (Cook) (Acari: Trombidiformes: Eriophyidae) on flower and fruit production by coppicing shoots, following pruning, of a widely distributed variety (light pink 163LP) of Lantana camara L. (Verbenaceae) in South Africa. Counts, at three different sites, of developed inflorescences, flowers and fruits and the extent of A. lantanae galling were done for coppicing shoots at four different stages of growth (3, 6, 9- and 12-months post-pruning).

- Description: The study examines the role played by the Mnquma Local municipality in addressing xenophobic violence in Butterworth between 2010 and 2012 and subsequent sporadic tensions. The study also examines the causes as well as the sporadic recurrence of xenophobic tensions between foreign shop owners and local community members in Butterworth. Due to the nature of the study, ethnographic fieldwork was considered the most practical and suitable method in getting necessary responses regarding the study. The data collection instruments used were in-depth interviews and focus group discussions. Participants comprised 15 foreign shop owners, 15 local community members. In addition, three interviews were conducted with relevant Mnquma Local Municipality officials who had been involved in addressing xenophobic tensions in Butterworth. In order to understand the dynamics of xenophobic tensions in Butterworth, the study employed two theories; the Scapegoating theory and Relative Deprivation theory. The study established that the causes of xenophobic tensions were largely due to the poor socio-economic situation in the Mnquma Municipality, which resulted in high rates of poverty, unemployment and competition for resources and business opportunities. Furthermore, misinformation on media platforms about foreign nationals and the inadequate opportunities for interaction also exacerbated tensions. Moreover, it was uncovered that the Mnquma Local Municipality did not have effective mechanisms to address xenophobic tensions. The study recommends that the municipality addresses service delivery needs of both locals and foreign nationals as this will create a safe and peaceful environment for foreign nationals to coexist with locals in Butterworth. x The study further urges the Mnquma Local Municipality to formulate an antixenophobia unit that can detect and combat any sign of xenophobia in all communities in Butterworth.

- Description: The current paper examines the unique contributions of phonological awareness (PA), rapid automatised naming (RAN) and morphological awareness (MA) to oral reading fluency (ORF) in isiXhosa. No published study has yet explored the individual contributions of these three cognitive-linguistic skills to reading in isiXhosa. Sixty-six grade 3 home language isiXhosa learners were assessed on these cognitive-linguistic skills. Results from a linear regression analysis showed that only RAN and MA, but not PA, were significant concurrent predictors of ORF. These results suggest that the role of PA in reading in grade 3 learners in isiXhosa may have been overestimated because other important predictors of reading have not been controlled. Our data also suggest that grade 3 isiXhosa learners may make use of the morpheme as a grain size in reading. Our study highlights the need for longitudinal research which explores the roles of PA, MA and RAN in reading development in order to inform reading pedagogy in isiXhosa and other Southern Bantu languages.

- Description: Small pelagic fish, including anchovies, sardines and sardinellas, mackerels, capelin, hilsa, sprats and herrings, are distributed widely, from the tropics to the far north Atlantic Ocean and to the southern oceans off Chile and South Africa. They are most abundant in the highly productive major eastern boundary upwelling systems and are characterised by significant natural variations in biomass. Overall, small pelagic fisheries represent about one third of global fish landings although a large proportion of the catch is processed into animal feeds. Nonetheless, in some developing countries in addition to their economic value, small pelagic fisheries also make an important contribution to human diets and the food security of many low-income households. Such is the case for many communities in the Zanzibar Archipelago and on mainland Tanzania in the Western Indian Ocean. Of great concern in this region, as elsewhere, is the potential impact of climate change on marine and coastal ecosystems in general, and on small pelagic fisheries in particular. This paper describes data and information available on Tanzania's small pelagic fisheries, including catch and effort, management protocols and socio-economic significance.
