- 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: Pentecostal churches in Nigeria are leveraging traditional and new media technologies such as cable or digital satellite television, to broadcast services and programmes to their regular and a growing community of virtual worshippers. Critics of this type of religious outreach now known as televangelism have challenged its predominant, if not exclusive focus on miracle and prosperity message. Using the mixed-method research design involving focus group discussions, key informant interviews and a survey of 255 respondents, this study sought to ascertain Lagos audiences‘ perceptions of Pentecostal Television programmes on two satellite stations, Start Times and DSTV. The findings revealed that audience members perceive Pentecostal churches programme as primarily focused on converting the audience members to the Christian faith. The result revealed that miracle sessions are a common feature of televangelism. Respondents see the miracles as manipulations largely intended to woo and often, hoodwink audience members. The findings revealed that although some of the Pentecostal churches‘ programmes dwell more on the word of God compared to the mainline churches, the programmes and teachings, however, often tended to promote the leadership of the church and not the gospel of Christ. Generally, the study indicates the majority of the audience members are aware of and identify with the atrocities the Pentecostal Churches are accused of perpetrating through their TV programmes. The findings revealed poor awareness and knowledge about the role of the Nigeria Broadcasting Corporation (NBC). The results suggest participants do not believe the NBC is living up to its responsibilities. The findings of this study highlight the need for the NBC, the Christian Association of Nigeria (CAN) and Pentecostal Fellowship of Nigeria (PFN) to work together in formulating new regulations for controlling religious broadcast on television, Pentecostal TV broadcasts, in particular. This is the only way to safeguard vulnerable members of the audience from being manipulated and brainwashed.

- Description: Infection control and prevention is an issue that is of utmost importance to every health practitioner, including professional nurses, as patients who undergo surgeries could develop sepsis, leading to failure of multiple organs and possibly death. Surgical site infections acquired from operating theatres are often introduced when there is lack of application of and adherence to the necessary control measures, sterile principles and techniques, including the appropriate use of surgical attire. This study aimed to contextualize, implement and evaluate an existing educational intervention regarding the use of surgical attire in operating theatres, in order to establish whether the educational intervention enhanced the practices of professional nurses in operating theatres regarding the use of surgical attire. A quantitative research design, using a quasi-experimental two-group pre-test, post-test intervention approach was employed for the study. The study consisted of three phases. Phase 1 consisted of the administration of the pre-test questionnaire relating to Objective One: “To explore and describe the practices of professional nurses on the use of surgical attire in the prevention of surgical site infections in operating theatres”. Phase 2 consisted of the contextualization and implementation of the educational intervention, which related to Objective Two: “To contextualize and implement an educational intervention for professional nurses on the use of surgical attire in the prevention of surgical site infections in operating theatres”. Phase 3 consisted of the administration of the posttest questionnaire, which related to Objective Three: “To evaluate whether an educational intervention regarding the use of surgical attire in the prevention of surgical site infections in operating theatres enhanced professional nurses’ practices”. The study is underpinned by the Promoting Action on Research Implementation (PARiHS) framework. The research sample consisted of all professional nurses working in the public and private operating theatres in the Nelson Mandela Bay Municipality. Purposive sampling was used to select the hospitals in control (Hospitals 2 and 3) and intervention groups (Hospitals 4 and 5), ensuring an equal number of public and private hospitals in each group. Data was collected through self-administered pre- and post-questionnaires. An existing educational intervention based on the Association of Perioperative Registered Nurses (AORN’s) guidelines was contextualized through review by three professional nurses with a specialty in operating theatre. The educational intervention was implemented for the intervention group, while the control group only received the summary of the AORN guidelines. Reliability and validity were ensured through the conduct of a pilot study, and expert review by three professional nurses with a specialty in operating theatre in order to check the validity and reliability of the data collection instrument and educational intervention. The data collection instrument was also reviewed by a statistician. Ethical clearance and permission was obtained from the relevant institutions. The following ethical principles were adhered to during the study: justice, respect and beneficence. The overall score of pre-test and post-test questionnaires for the control group revealed means of 3.96 and 4.01, with a standard deviation of 0.40 and 0.38, with a difference of -0.06 and a degree of freedom of 59. The overall score of the pre-test and post-test of the intervention group revealed means of 3.68 and 4.22, a standard deviation of 0.47 and 0.36, with a difference of -0.53, degree of freedom of 61 and a large significance difference of Cohen’s d= 1.26. This means that the educational intervention had a positive effect in terms of improving the professional nurses’ practices on the use of surgical attire to prevent surgical site infections in operating theatres. Recommendations for education, practice as well as future research were provided.

- Description: Meteorological processes such as tides influence ionospheric variability through vertical coupling. For the first time, we have used data from Communication Navigation Outage and Forecasting System (C/NOFS) satellite from 2008–2015 to develop a Neural Network (NN) vertical E×B drift model over the African region, with inclusion of a proxy of tides as one of the inputs together with other physical and geophysical inputs. Two models (with and without tidal proxy input) were developed for both East and West African sectors. To derive the tidal proxy, we first calculate the 60-day running means per year which were subtracted from the actual vertical E×B drift measurements to obtain a set of residuals. The purpose of the subtraction was to remove long-term trends in vertical E×B drift that could potentially alias into tides.

- 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.

- Description: This research study is qualitative and cross-sectional in nature. Programme management by South African city governments is investigated and evaluated, as related to inner-city decay and problem (derelict; hijacked; dilapidated; overcrowded) buildings. A case study approach, focusing on the Nelson Mandela Bay Municipality in Port Elizabeth, South Africa, is utilised to understand the phenomenon, and to answer the research question. The significant challenge of inner-city and central business district problem buildings in major South African cities has prompted the study; no scientific research has previously been conducted or published on this topic The study started out with this research question, asked in a case study context: to what extent are programmes dealing with inner-city problem buildings and decay managed effectively by city government in South Africa? In the literature review the researcher focused on programme management theory, emphasising the usefulness of project management principles and practice in public sector programme management contexts. In a subsequent chapter the applicable constitutional and legislative frameworks were presented. The researcher developed, as outcome, strategic remedial legal options available to city governments when dealing with transgressing owners of problematic buildings. Problem building by-laws were dealt with in detail. A qualitative research approach, including semi-structured in-depth interviews with political and managerial leaders at the case study city government, assisted the researcher in effective data generation. Data analysis was performed with vigour, based on thematic content analysis.relevant coding practices were utilised in analysis and interpretation of data.

- Description: The concept of sustainability has received considerable attention over the last few decades (Scoones, 2007). International awareness and demands for sustainable development have pushed the sustainable narrative into the forefront of developmental goals. The Brundtland Report of 1987, released by the United Nations entitled “Our Common Future” resulted in the classic modern definition of sustainable development. Agriculture is the primary source of food, shelter and fibre for the world and therefore has a leading role to play in the realisation of a sustainable future (Van Calker, Berentsen, Giesen and Huirne, 2005). Most sustainability research in agriculture has adopted a particular scale and dimension, leading to a host of definitions and methodologies for its assessment (Hayati, 2017, Janker and Mann, 2018, Latruffe, Diazabakana, Bockstaller, Desjeux and Finn, 2016, Smith and McDonald, 1998). Different approaches to assessing sustainable agriculture have developed in hand with various conceptual methods resulting in a lack of a common understanding of what sustainable agriculture means (Janker and Mann, 2018, Smith and McDonald, 1998). Agriculture has a leading role to play in sustainable development in the South African context; however, commercial agriculture in South Africa has been associated with human rights violations as well as unsustainable social practices and exploitation of employees (Mather, 2007, Muller, Vermeulen and Glasbergen, 2012b). This research was conducted in an agri-processing company that had expanded rapidly and been experiencing high absenteeism and increased conflict in the work environment in an attempt to identify how many of the chosen indicators of on-farm internal social sustainability were present in the company. The literature review helped to contextualise the subject of sustainability, agricultural sustainability, agricultural social sustainability and various methods for assessing agricultural sustainability. The subject of agriculture social sustainability within the South African context was expanded upon, and a framework was selected from the literature to develop the aims of this research. The Barrientos and Visser (2013) framework had been utilised in evaluating social sustainability in the South African agricultural context before, and when compared with relevant literature was deemed appropriate for this research. Through the use of a case study approach, thirty employees were interviewed on a one on one basis with close ended questions. Data was collected through the use of an odd-numbered Likert scale and simple descriptive statistics were used to answer questions regarding which socially sustainable on-farm internal indicators, identified in the literature and in the chosen framework, occurred in the company in question. The research looked to further critically evaluate the aspects of social sustainability that were implemented by the company and discuss the challenges relating to those identified indicators that were not implemented. Finally, the research made recommendations to improve the on-farm internal social sustainability of the company in question. The results of this research showed that out of the ten indicators of on-farm internal social sustainability that were relevant in the framework, five were present in the company in question and five were absent. Those indicators that were present were: contracts, wages, benefits, communication with management and adequate representation. Indicators that were not present included health and safety, employee wellbeing, the level of discrimination, the level of harsh treatment and employee decision making. It was apparent from the results that there are many challenges to implementing on-farm internal socially sustainable policies and practices in the company. Chief amongst these challenges was communication with employees concerning policies that have been implemented and the information that is available to the employees regarding these policies. The company at the centre of this research should ensure that policies are put in place that helps to convey information to employees and ensure that the policies are implemented efficiently and effectively. It was recommended that the company initiate a Human Resources division that would be responsible for communication and the implementation of policies to increase on-farm internal social sustainability. By increasing social sustainability in the workplace, the company should be able to increase its efficiencies and effectiveness in a competitive global market. The researcher is aware that the findings of this research are not generalizable and are specific to the company in question both in terms of scale and location. Further research is needed to determine the impact of individual indicators and the weighting of each indicator in a specific environment. Further research should be conducted in a company that is in a similar industry and has similar staff demographics to the company at the centre of this research, as the scale of measure will influence the results.

- Description: This study focuses on an evaluation of communication effectiveness between the school administration office in Nelson Mandela Bay and its representative schools in advancing the business case of school development and heightened learner experience in line with the national development goal. The research uses a qualitative research approach to gather rich insights into the challenges, opportunities and problems that heighten and affect the quality of communication methods, channels and the roles of communication that the interviewed stakeholders representing both the district and schools depict and understand within the communication processes and methods used. Fourteen interviewees were identified using a judgemental and purposive sampling technique. They were identified from the Nelson Mandela Bay district office and schools within the district. Findings from the study reveal that the critical areas of concern include the roles of communication, stakeholder roles in the communication process, methods of communication, and challenges in communication effectiveness. While schools and the district office share the responsibility for providing quality education, it is critical that an effective communication strategy, which embraces computer-mediated communication as a supplementary tool, should be adopted to ensure that this shared mandate could be achieved.

- Description: This study evaluates the Integrative Propositional Analysis (IPA) (Wallis, 2015), and its usefulness as a complementary model for analysing and evaluating public policy and policy implementation. The IPA model is evaluated in this longitudinal study and seeks to establish the validity of the correlation between the historically implemented results of the Drakenstein Local Municipality Housing Policy against the complexity and systemicity scores of the policy between 2010 and 2017. The IPA model predicts that the higher the complexity and systemicity of the internal logic structure of a policy, the more useful and effective the policy will be, and for its successful implementation. The model is premised on the idea that policies are more useful when they have some level of structure and has been accepted widely for some time (Wallis, 2018). The study thus is an evaluation of the usefulness of the model as complementing policy analysis and evaluation for successful implementation based on the policy internal structure. The research study provided a brief historical background on the development of the IPA and locates it as a ‗science two‘ model based on its systems thinking and Complexity Theory properties to policy analysis. An extensive literature review was undertaken, and secondary data was gathered and analysed to gauge the policy‘s historical success. In examining the Drakenstein‘s housing policy outcomes for evaluating the IPA model, the study adopted both qualitative and quantitative approaches for this exploratory descriptive report. The diagnosis indicated that the revised targets, introduced during the implementation altered the vision of the policy. This allowed for an analysis of the low structure of the policy and its inability to create integrated sustainable human settlements.

- Description: Inclusive learning around the world takes into account both the rights of learners and how education systems can adapt in just and equitable ways to respond to learner differences. White Paper 6, launched by the Department of Education in 2001, has been praised in this regard as a groundbreaking post-Apartheid strategy that provides the vision and basis for turning the fragmented and unequal education system in South Africa into one that is inclusive. This represents a fundamental change from an academic placement process throughout the education system to an influx of educational support services. This study specifically explores how one Eastern Cape District Based Support Team perceives its roles and responsibilities. To investigate these viewpoints, a qualitative research model was used within an interpretive framework. For the choice of participants in the study, purposeful sampling methods were used. Data was collected and analysed using thematic data analysis through semi-structured individual interviews and a single focus group interview. The following key findings were revealed in the results. On the one hand, there are significant factors that allow the efficacy of District Based Support Teams as enabling agents of inclusion to be supported. These include: • A substantial degree of alignment between inclusive education theory and current inclusive education policy; • Enabling inclusive education policy and guidelines; • The interpretation of inclusive education by research participants and the goals of inclusive education are aligned with the policy they see as a framework to direct and encourage their practice; • The District Based Support Team's view of their position is basically that of support service with the primary responsibility to allow inclusive learning to be implemented. On the other hand, structural debilitating factors substantially weaken these teams ' effectiveness. These include:South African School and Administration Management System • Early identification of obstacles and admission age • Budget • Support tools/ equipment • Human Resources - human and physical resources • The unproductive inclusion of special schools as resource centres in the District Based Support Teams. • Poor infrastructure • Coordination and cooperation with the National DoE to enforce IE policies. Years after its adoption, the key challenge remains the translation of encouraging policy language into practical action at all levels of the process within the broader context of the failure of Inclusive Education Policy to have any significant impact on the education system. At the district level, it needs innovative leadership across the Specialised Education Support Unit (including District Based Teams and Special School Resource Centers) and firm management within it to allow organisational coordination and intersectoral cooperation within an integrated community context.

- Description: Zimbabwean teacher educators are, by the nature of their job description, required to supervise student teachers doing teaching practicum for the 0-3 home based programme. However, analysis of supervision reports of the home based programme indicates some inconsistencies in comments made by different supervisors, whereby the descriptors and supervision overall scores do not tally. It seems the supervision of the home based teacher education programme is not being implemented as expected. Hence, the purpose of this qualitative case study was to examine practices and experiences of teacher educators in the supervision of a National Early Childhood Development Home Based Teacher Education Programme (NECDHBTEP). The objective of the study was to address the key question: ‘What are the practices and experiences of teacher educators in the supervision of a NECDHBTEP. In addressing the question, the researcher used supervision as a conceptual framework. The theoretical framework which informed the study was Contextual Supervision (CS) which has its philosophical foundations in constructivism, beneficence and justice. Purposive sampling was employed in the study where two primary teachers’ colleges were selected. From each college, ten teacher educators were selected for semi-structured interviews, two focus group discussions and document analysis on teacher educators’ supervision reports. Triangulation of the data was done so as to enhance its trustworthiness. Three major themes emerged from the study, namely, the influence of home context, experience of supervisors on NECDHBTEP and supervision approaches. The study discovered that the home context, to some extent, influences supervision of the NECDHBTEP. The study also established that teacher educators face multiple challenges when supervising student teachers on the ECD home based programme. The researcher made some recommendations from the findings. One of the recommendations was for colleges to develop a specific supervision instrument for the home based ECD supervision (0-3 years category). Furthermore, there is need for Zimbabwean primary teachers’ colleges to engage in rigorous in-service training for lecturers who are not knowledgeable about the NECDHBTEP.

- Description: Zimbabwean teacher educators are, by the nature of their job description, required to supervise student teachers doing teaching practicum for the 0-3 home based programme. However, analysis of supervision reports of the home based programme indicates some inconsistencies in comments made by different supervisors, whereby the descriptors and supervision overall scores do not tally. It seems the supervision of the home based teacher education programme is not being implemented as expected. Hence, the purpose of this qualitative case study was to examine practices and experiences of teacher educators in the supervision of a National Early Childhood Development Home Based Teacher Education Programme (NECDHBTEP). The objective of the study was to address the key question: ‘What are the practices and experiences of teacher educators in the supervision of a NECDHBTEP. In addressing the question, the researcher used supervision as a conceptual framework. The theoretical framework which informed the study was Contextual Supervision (CS) which has its philosophical foundations in constructivism, beneficence and justice. Purposive sampling was employed in the study where two primary teachers’ colleges were selected. From each college, ten teacher educators were selected for semi-structured interviews, two focus group discussions and document analysis on teacher educators’ supervision reports. Triangulation of the data was done so as to enhance its trustworthiness. Three major themes emerged from the study, namely, the influence of home context, experience of supervisors on NECDHBTEP and supervision approaches. The study discovered that the home context, to some extent, influences supervision of the NECDHBTEP. The study also established that teacher educators face multiple challenges when supervising student teachers on the ECD home based programme. The researcher made some recommendations from the findings. One of the recommendations was for colleges to develop a specific supervision instrument for the home based ECD supervision (0-3 years category). Furthermore, there is need for Zimbabwean primary teachers’ colleges to engage in rigorous in-service training for lecturers who are not knowledgeable about the NECDHBTEP.

- Description: This research investigated formative assessment in primary school Natural Sciences classrooms. The intention was to explore how teachers use formative assessment strategies to raise classroom standards and to foster higher order cognitive development of learners. My interest in the study was influenced by constant poor achievement of South African learners in literacy and specifically in scientific literacy reported in various international and national benchmark tests. Vygotskian theory of the zone of proximal development was used to provide critical insight into formative assessment processes. Further theoretical lenses included Wylie and Lyons’ (2013) ‘Ten dimensions of formative assessment’ work for reviewing formative assessment strategies and Dalton’s (2003) ‘New Bloom’s Taxonomy’ for insight into cognitive development in classroom contexts. Influenced by the above mentioned reports, a qualitative case study of seven primary school teachers in Cape Town, Western Cape, South Africa was conducted. Underpinned by an interpretive paradigm and driven by the desire to achieve an in-depth understanding of the case under study, three techniques for data generation were employed. The first technique was semi-structured interviews. The second technique of data generation was through lesson observations including pre-lesson discussions and stimulated recall interviews. Observations were conducted to record teachers’ formative assessment practices and report how they use the formative assessment strategies to support student learning or ‘shifting’ their zone of proximal development through formative assessment practices. The third technique was document analysis of lesson plans, teaching and learning activities and assessment tasks worksheets of the two teachers observed. Documents were analysed to gain insights and understanding of how teachers prepared teaching and learning activities and assessments to support learner cognitive development. There were four data analysis phases. Phase I was an analysis of the semi-structured interviews. These were analysed to get a sense of teachers’ perspectives, experiences and challenges regarding formative assessment practices. In order to get a better sense of the quality of formative assessment, classroom observations were analysed using the lens of Wylie and Lyon (2013). This was analysis Phase II. Phase III made use of Dalton’s ‘New Bloom’s Taxonomy’ to gain insight into the role of formative assessment in supporting low, medium and higher order cognitive development. This phase was the document analysis and involved a review of the lesson plans, teaching and learning activities and formative assessment tasks. Phase IV further explored teachers’ experiences regarding implementation of formative assessment. Phase IV is different from Phase I in that it was not only looking at what teachers highlighted as challenges but also at challenges experienced during the lesson observations. This analysis was done across data sources, that is, semi-structured interviews, lesson observations and stimulated recall interviews. Findings from the first set of data showed that teachers viewed formative assessment implementation as a useful practice in the teaching and learning process. However, the diverse views showed lack of clarity of the purpose and definition of formative assessment. The results also revealed some effective attributes of formative assessment were observed during lesson observations at the time of the investigation. However, the results showed that clarifying goals, feedback and classroom collaborations were weakly implemented. These seem to be strategic entry points to begin strengthening the effective implementation of formative assessment classrooms. Supporting teachers regarding use of formative assessment techniques could be one of the means of helping teachers in collecting evidence of student learning. The teachers highlighted some challenges they experienced when implementing formative assessments. Hindrances to implementing effective formative assessment practice reflected structural, technical and attitudinal challenges. The study recommends that since formative assessment is a fundamental part of teaching and learning, teachers need more support and time for reflection to improve their implementation of effective formative assessment. The study also revealed that teachers need enough time to be able to implement effective formative assessment practices. This requires curriculum developers and administrators to revisit curriculum coverage in terms of breadth and depth and to give more time for the implementation of effective formative assessment practices.

- Description: Some studies have looked at Foundation Phase teachers’ perspectives on the teaching of science in this phase. Such studies have highlighted various challenges on the teaching of science in the Foundation Phase. They pointed out issues such as large class numbers, lack of resources and lack of science knowledge from Foundation Phase teachers. However, none of these studies have looked at how Foundation Phase teachers are using an Inquiry-Based Approach in their classrooms instead few studies have looked at the Foundation Phase teachers’ perspectives about scientific inquiry in this phase. Even though many scholars have presented several challenges to the teaching of science both at secondary and primary level, the argument is strongly made that Foundation Phase learners should be exposed to the learning of science. Generally, children at the Foundation Phase level naturally enjoy observing and thinking about nature; exposing learners to science develops positive attitudes towards science; the use of scientifically informed language at an early age influences the eventual development of scientific concepts; children can understand scientific concepts and reason scientifically; and science is an efficient means for developing scientific thinking. It is within these arguments and discussions that this interpretive case study research sought to explore the Pedagogical Content Knowledge of four Foundation Phase teachers in developing the Scientific Process Skills using an Inquiry-Based Approach in their classrooms and subsequently, the significance of this research study. The socio-cultural theory, Topic Specific Pedagogical Content Knowledge, Zaretskii’s six conditions for development during mediation and the principles of an Inquiry-Based Approach were used as analytical lenses in this research. To use an Inquiry-Based Approach, generally teachers have to understand its principles and know how to develop basic Scientific Process Skills while teaching the science content. In the Foundation Phase, the Natural Sciences component or content is embedded in the Beginning Knowledge study area of the Life Skills subject and this can create difficulties for teachers to even recognise the scientific concepts in the Life Skills. The four IsiXhosa female teachers used the home language of learners as the language of instruction to implement an Inquiry-Based Approach in their classrooms. Data were generated in four phases. Phase one was baseline data through document analysis. Three of the phases were directed by the research question asked. Data were generated using questionnaires, interviews (semi-structured and stimulated recall), lesson observations (videotaped) and group reflections and discussions. From the work of Vygotsky, Zaretskii formulated six conditions that can be used to develop learners’ zone of proximal development in learning and these were used as analytical lenses to analyse data to understand how teachers mediated learning and development of Scientific Inquiry in their Grade 3 classrooms. In addition, the principles of an Inquiry-Based Approach were used as analytical lenses as to how teachers implemented the scientific inquiry approach. The categories or components of Topic Specific Pedagogical Content Knowledge were used as analytical lenses as to how these teachers dealt with science concepts or content when using an inquiry-based Approach in their classrooms. Using the home language of learners as an instructional tool, data showed that learners were afforded the opportunity to freely engage in activities and as a result, the context of learning was non-threatening for both teachers and learners. Although learning activities could be improved, teachers created social spaces for learners to take part in learning. In addition, the use of learners’ environments in the observed lessons made it comfortable for learners to act as young scientists. The new knowledge in this research was presented by the use of the adapted analytical tool, which combined diverse components of theory and literature that aligned with each other. The reflection space for the participants did not only afford the participants to discuss about each other’s lessons or experiences in this research, it allowed the participants to engage with the research objectives. The reflection space strengthened the research ethics if this study. Hence, the concept that says, ‘Absenting the absences’. In conclusion, the study thus recommends further professional development spaces that promote community of practice in using an Inquiry-Based Approach in the Foundation Phase.

- Description: The aim of this study is to investigate the organizational expectations of different generations of employees at the Ministry of Finance’s Inland Revenue and Customs and Excise Departments of the Republic of Namibia, which are undergoing organizational change processes. The different generations that were included in this study are Baby Boomers, Generation X, and Generation Y. The study explores the different expectations that the generations have in relation to the changes, in terms of leadership style and communication preferences. This study followed a qualitative approach. Quota sampling was used to select twelve participants for the study. The case study was carried out within a postpositivism paradigm. Data was collected by administering semi-structured, face-to-face interviews. The findings of the study indicate that there are generational differences in respect of preferred leadership styles and communication methods during organizational change. Baby Boomers and Generation X preferred a relationshiporiented leadership style, while generation Y preferred a visionary leadership style. Task-oriented leadership style was not the preferred style of any generation. Rather, in the midst of change, it seems there is a preference for relational leadership across all the Generations. In respect of communication, Baby Boomers preferred face-toface methods, Generation X preferred face-to-face and e-mail methods as sources of change communication, while Generation Y preferred a combination of communication methods. In the midst of change, it seems there is a common preference for face-to-face communication across all the Generations. Furthermore, employees generally did not feel ready for the changes. In the light of these findings, recommendations were made to guide change initiatives amongst employees of various generations. The limitations of the study were its sample size and focus on the public sector. For future research, a larger sample could be selected from all regional offices. Similar research can also be done in the private sector. The findings of the study provide an understanding of the experiences and expectations of different generations of employees during organizational change, and contribute to the body of knowledge on generational differences, readiness for change and the management of different generations as different stakeholders.

- Description: Organisations and individuals are facing increasing persistent threats on the Internet from worms, port scanners, and malicious software (malware). These threats are constantly evolving as attack techniques are discovered. To aid in the detection and prevention of such threats, and to stay ahead of the adversaries conducting the attacks, security specialists are utilising Threat Intelligence (TI) data in their defense strategies. TI data can be obtained from a variety of different sources such as private routers, firewall logs, public archives, and public or private network telescopes. However, at the rate and ease at which TI is produced and published, specifically Open Source Threat Intelligence (OSINT), the quality is dropping, resulting in fragmented, context-less and variable data. This research utilised two sets of TI data, a collection of OSINT and active Internet Background Radiation (IBR). The data was collected over a period of 12 months, from 37 publicly available OSINT datasets and five IBR datasets. Through the identification and analysis of common data between the OSINT and IBR datasets, this research was able to gain insight into how effective OSINT is at detecting and potentially reducing ongoing malicious Internet traffic. As part of this research, a minimal framework for the collection, processing/analysis, and distribution of OSINT was developed and tested. The research focused on exploring areas in common between the two datasets, with the intention of creating an enriched, contextualised, and reduced set of malicious source IP addresses that could be published for consumers to use in their own environment. The findings of this research pointed towards a persistent group of IP addresses observed on both datasets, over the period under research. Using these persistent IP addresses, the research was able to identify specific services being targeted. Amongst these persistent IP addresses were significant packets from Mirai like IoT Malware on port 23/tcp and 2323/tcp as well as general scanning activity on port 445/TCP.

- Description: Introduction: Sports participation has been associated with a number of benefits to young athletes, outside of purely physical health. One of the key components of a successful sports talent identification and development program is effective coaching. A foundation of effective coaching is the coach’s knowledge which can be developed through formal, non-formal and informal means of education. The majority of coach education literature has however focused on coaches from developed countries. Limited studies have looked at the educational experiences and needs of South African coaches, particularly football coaches. The purpose of the current investigation is to establish Local Football Association (LFA) coaches’ perceptions of their educational backgrounds and what knowledge they deem important to be effective coaches. Method: A mixed methods approach was used in which (n=25) Makana LFA coaches answered a questionnaire with the aim of identifying their educational histories and what their current educational needs were. A semi-structured interview was also implemented in which some of the respondents (n=4) were asked more in-depth questions around the same topics, to create a more complete coaching profile. Results: The questionnaire responses highlighted that only 8% of the coaches possess a formal coaching qualification and all of the coaches work on a volunteer basis. Previous experience as a player is the chief source of knowledge for Makana LFA coaches. Not having enough available time is the main perceived barrier for 56% of participants to seeking out further educational opportunities. Fundamentals of coaching was selected by 56% of the coaches as a key subject they want to learn more about. Findings from the interview demonstrate that participants coach multiple teams and often have to rely on senior players to take up assistant coach positions, as well as managing their time effectively to work with all their teams. Informal education is the main source of information for the coaches which includes asking for advice, reading coaching manuals or having a mentor. The coaches value all 3 forms of education, however non-formal workshops are favoured. This is due to all of the coaches already having some form of informal learning experience and formal learning opportunities being too costly to pursue. A combination of lectures, practical sessions and group discussions is desired as a delivery method of coaching knowledge. Discussion: The level of coaching qualifications in the LFA is low, this may have significant implications for talent identification and development in the Sarah Baartman region. All the coaches are volunteer coaches, who primarily rely on informal means of coaching education. ‘Time’ was indicated to be a major barrier, to coaches seeking out educational opportunities. Coaches indicated that they would benefit from a coaching program if it took into consideration their needs, such as wanting to learn more about interpersonal and intrapersonal awareness. Conclusion: If local coaching programs are to be effective, they must reflect the educational needs of their community.

A combination of lectures, practical sessions and group discussions is desired as a delivery method of coaching knowledge. Discussion: The level of coaching qualifications in the LFA is low, this may have significant implications for talent identification and development in the Sarah Baartman region. All the coaches are volunteer coaches, who primarily rely on informal means of coaching education. ‘Time’ was indicated to be a major barrier, to coaches seeking out educational opportunities. Coaches indicated that they would benefit from a coaching program if it took into consideration their needs, such as wanting to learn more about interpersonal and intrapersonal awareness. Conclusion: If local coaching programs are to be effective, they must reflect the educational needs of their community.

- Description: Universities, especially those publicly funded by the government are at the edge of the economic woes when budget allocation is cut to support their operations. University should not only focus on research and the traditional role of teaching but, to become innovative by creating third stream income generation projects and activities. This would enable them to bridge the gap in financing from the state. The main goal of the study is to explore whether the university has opportunities to become entrepreneurial. The researcher analyzed the study from the perspective of internal capabilities the institution owns and how these capabilities can be applied to create a competitive advantage and external opportunities for the institution. To achieve the objectives of this study, the researcher employed a case study research design approach. The study was embedded in the interprevists paradigm and, following an inductive approach. The study had a population of 14 Centres at UNAM where a sample of 4 Centres was purposively selected to represent the population because they were responsible for research and entrepreneurship activities. Documents review and semi-structured interviews were used to collect secondary and primary data respectively, which helped in the triangulation to avoid data error. These methods also allowed the researcher to ensure credibility, transferability, trustworthiness and external validity. To adhere to all ethical regulations and procedures, the researcher obtained the ethics approval from the Rhodes Ethics Committee, which, was then used to obtain Gatekeeper permission from UNAM. The study found that UNAM has the internal capabilities required that provides them an opportunity to become entrepreneurial. Through its Innovation and Development Department in collaboration with Inceptus, a UNAM commercial owned holding company. The study recommended that UNAM put structures in place, to begin with, all entrepreneurial projects towards securing third stream income as well as expanding research that focuses on leadership and governance.
