- Description: As a clinic supervisor overseeing a cluster of clinics in the Nelson Mandela Bay Health District (NMBHD), the researcher observed a number of problems with the implementation of the re-engineering of the primary health care (RPHC) programme. The problems observed include inadequate supervision of RPHC staff, poor communication and conflict between clinic and RPHC staff, failure to filter RPHC statistics into clinic statistics and the incorrect management of patients by RPHC staff. Therefore, the purpose of this study is to explore and describe the experiences of professional nurses regarding the implementation of the RPHC programme in the NMBHD and to make recommendations the district manager could use to address the research findings. The study used a qualitative, exploratory, descriptive and contextual design. The research population consisted of professional nurses who are implementing the RPHC programme in the NMBHD, and the sampling technique was a non-probability, purposive technique for the selection of the research sample. Semi-structured interviews were used to collect the data and Tesch’s model respectively. The researcher adhered to ethical considerations throughout the study and ensured trustworthiness of the data by using the criteria of credibility, transferability, dependability and conformability. Three themes were identified; namely; the professional nurses expression of their concerns regarding poor working conditions; issues regarding the community health workers and their positive experiences associated with the RPHC programme. The study concludes with recommendations made to the District manager with regard to nursing practice, as well as recommendations to nursing education and research.

- Description: This study examined experiences of teachers in ex-Model C secondary schools in Port Elizabeth with specific reference to the strategies adopted, challenges and rewards of teaching in diverse classrooms. It is located in the realm of diversity pedagogy and multi-cultural education and contextualized against the socio-political and colourful historical climate of education in South Africa. This study was conducted by using the qualitative research approach against the backdrop of the phenomenological design according to the interpretivist paradigm. Data were elicited through in-depth semi-structured interviews with 16 teachers from 4 ex-Model C English medium secondary schools (formerly White schools) who had experiences of teaching both pre-1994, when schools were mono-ethnic, and post-1994 when the schools were multi-ethnic. The interviews were transcribed and the rich thick data were analysed and categorized into themes and sub-themes by adopting a constant comparative method. The findings of the study indicate that teachers failed to embrace diversity to its fullest, although they did not mind teaching diverse learners. Furthermore, it is evident that they have not made concerted efforts to implement culturally responsive teaching strategies to cater for diversity in their classes as the approaches tend to be cosmetic and superficial. The findings indicate that teachers are stuck in the quagmire of business as usual-, colour-blind-, assimilationist, contributionist approaches that militate against culturally responsive pedagogy. It is recommended that teachers be empowered with skills in diversity education by various stakeholders such as School Governing Bodies, the Department of Basic Education and teacher unions so that they are better equipped to implement strategies in their classes that cater to the needs of a diverse learner population.

- Description: The extended role of today’s pharmacist with the emphasis on patient-focused care has highlighted the need for increased exposure of undergraduate pharmacy students to experiential learning in patient-centred environments, and additional skills development in therapeutics, problem solving and clinical decision making. At the Nelson Mandela Metropolitan University (NMMU), final year pharmacy students complete a university-coordinated, hospital-based, structured experiential learning programme (ELP) for the exit-level module, Pharmacology4. However, the students consistently experience difficulties in the application of pharmacological knowledge during the transition from lecture-based learning to the patient-focused clinical setting. The student population at the NMMU is diverse, with varied cultural, ethnic, language and secondary level education backgrounds, as well as different learning preferences and approaches. The extent to which these factors affect academic achievement in the experiential learning environment is unknown. Central research question The central research question for this study was therefore, “What would be the effect of an intervention aimed at supporting undergraduate pharmacy students during clinical placements, on academic achievement in, and student attitudes towards, experiential learning programmes (ELP)?” In order to explore the research question, several factors which may influence academic achievement in ELPs were investigated, namely: academic achievement (pre-university, in the BPharm programme and, in pharmacology); the admission route into the BPharm programme and the subsequent rate of academic progression; English reading comprehension ability; learning styles; problem solving ability; the extent to which students are prepared for application of knowledge in the ELP, in terms of assessment methods used prior to the final year and previous pharmacy work-based experience. In addition, the students’ lived experience of the ELP was explored, and the need for, and nature of, an intervention was determined. The research was based in a pragmatic paradigm, using an advanced mixed methods approach. An intervention-based, two-phase, quasi-experimental design was employed with an initial exploratory Preliminary Phase (in 2013) preceding the larger experimental framework (Phases One and Two, in 2014 and 2015 respectively). The research design was primarily quantitative, with pre- and post- testing conducted before and after the ELP. The ELP was completed by the comparator cohort in Phase One and the experimental cohort in Phase Two. Supplementary qualitative data was collected before, during and after the ELP. The intervention, in the form of supplementary academic support sessions, was developed from the qualitative data using an iterative approach, and implemented during the ELP in Phase Two. Attitudes and expectations of the students towards the hospital-based ELP were generally positive and realistic. Areas of concern included the difficulties experienced in the application and integration of pharmacological knowledge, both in the clinical setting and the clinical case study-based assessments; students feeling overwhelmed, inadequate and inferior in the clinical environment, compounded by an absence of clinical pharmacists as role models; and feeling unprepared for patient-focused care. The qualitative data strongly supported the need for supplementary academic support sessions. The intervention was developed and implemented in Phase Two, using patient case-based, active learning strategies. The majority of students (91.0%; n = 104) reported improved case analysis skills. A statistically significant (p = .030, Cohen’s d = 0.34) improvement was noted in the summative Pharmacology4 assessment marks obtained by the experimental cohort post-intervention, although of small practical significance. Predictors of academic achievement in the ELP were found to be language, specifically English reading comprehension skills, academic achievement in the BPharm programme and pharmacology, the university admission score, the rate of academic progression, and problem solving ability. Previous pharmacy-based work experience and assessment questions requiring application of knowledge were also found to influence achievement in the ELP. The need for an intervention in the form of supplementary academic support sessions was confirmed. The intervention was subsequently developed and successfully implemented, with student-reported self-perceived improvements in patient case analysis skills. These positive findings were supported by quantitative data which showed a statistically significant improvement in academic achievement in the ELP. Several predictors of academic achievement in the ELP were identified, and invaluable insight was gained into the nature of the difficulties experienced by pharmacy students in the transition from lecture-based learning to experiential learning in patient-focused environments.

- Description: In this study, tetra-(4-propargyloxy)phenoxy phthalocyanines (MTPrOPhOPc) were covalently immobilized as thin films onto gold surfaces via click reaction. The gold electrode surfaces were pre-functionalized with phenylazide (Au-PAz) thin film using in-situ diazonium generation followed by electrografting. Copper (I) catalyzed alkynyl-azide cycloaddition (CuCAAC) reaction was used to covalently immobilize the MTPrOPhOPcs onto the gold electrode surfaces to form Au-PAz-MTPrOPhOPc. The MTPrOPhOPcs were further studied for their electrocatalytic and electroanalytical properties towards the detection of hydrogen peroxide. Au-PAz-MTPrOPhOPc exhibited good reproducibility and stability in various electrolyte conditions. Electrochemical and spectroscopic surface characterization of the functionalized gold electrode surfaces confirmed the presence of the phenylazide and MTPrOPhOPc thin monolayer films. The excellent electroanalysis of hydrogen peroxide with the limit of detection (LoD) and limit of quantification (LoQ) in the μM range was obtained. The electrocatalytic reduction peaks for H2O2 were observed at −0.37 V for Au-PAz-Mn(OAc)TPrOPhOPc and −0.31 V for Au-PAz-CoTPrOPhOPc when Ag|AgCl pseudo-reference electrode was used. The Au-PAz-Mn(OAc)TPrOPhOPc and Au-PAz-CoTPrOPhOPc gold electrode surfaces showed good sensitivity and reproducibility towards the electrocatalytic reduction of hydrogen peroxide in pH 7.4 phosphate buffer solution.

- Description: Commercial trading in various formats has characterised relations between humans for centuries. However, in a world driven by higher levels of consumption, and where citizens demand higher returns for their hard-earned taxes, governments are becoming more active in ensuring favourable conditions for their own enterprises, either operating or seeking to operate, in foreign markets, as well as local enterprises that seek to extract value from foreign markets. The past failure of the markets to self-regulate, with the recent events of the 2008/09 market crash, gave fresh impetus for governments to play a more active role in ensuring favourable outcomes for their local economies. To be effective, requires the deployments of capable officials to fulfil this mandate. However, given that governments have traditionally not operated in the sphere of what is termed as ‘commercial diplomacy’, it is evident that a concerted effort needs to be made to have a skilled and capable workforce which can function in both the commercial and diplomatic market spaces across the world. Against the background sketched above, the South African government, with the dti spearheading the initiative, has been running capacity building programmes to train officials as designate FERs, to function as commercial diplomats in targeted foreign markets. This contrasts with its sister-department, DIRCO, which has established 126 foreign missions focusing on political diplomacy. Anecdotal evidence, and previous capacity building reports, have highlighted the need for a framework to regulate and inform the development of officials. Due to the framework’s broader focus, and the acknowledgement of the rich experiences of the officials being trained in the programme, it has been termed as capacity development. An initial review of the topic, revealed that there had been limited research into a framework that regulates the capacity development of foreign economic representatives (FERs), the term used for commercial diplomats of the South African government. Thus, the purpose of this study was to explore a capacity development framework (CDF) for South African FERs. This exploratory capacity development framework will then be tested, to inform the capacity development programme used for the training of designated FERs. To achieve this goal, a literature review of academic sources of information regarding the concepts of commercial diplomacy, capacity development and conceptual frameworks, was conducted. This led to the development of a qualitative questionnaire which was then distributed to all currently posted (27) and returned FERs (33), with 18 completed questionnaires returned. The questionnaire contained both closed and open-ended statements that delved deeper into the experiences and opinions held by the respondents. Using the dti as a case study, the content analysis method, which uses open coding, was applied to identify the theme and codes emanating from the data. This was assessed against the research questions (RQs) constructed in the research proposal, and was found to be in line with the sentiments flowing from the research data. The theme, indicated as capacity development and its concomitant codes (Process, Content, Technology and Management Support), thus formed the basis and skeleton of the exploratory capacity development framework. The codes were further analysed and sub-codes identified, which were incorporated into the exploratory capacity development framework. The analysis further revealed that, while the dti is committed to ensuring the designate FERs are adequately capacitated before being posted, much more could be done to improve the efficacy of the training provided. To this end, a number of gaps were identified from the data and these will need to be addressed to ensure that an effective capacity development programme is developed.

- Description: This thesis reports on an action research case study into the use of a genre-based approach (GBA) in teaching the writing of explanation texts to Grade 11 learners in Ohangwena Region, Namibia. Knowledge of how to write different genres is a requirement of the Namibian curriculum, and in particular the Grade 11-12 English Second Language [ESL] syllabus. The study aimed to improve my pedagogic practice in the teaching of genre as an English Second Language [ESL] teacher. It also aimed to further develop my Grade 11 learners’ academic language proficiency in genre writing. I employed two action research [AR] cycles. The first cycle was aimed at establishing learners’ baseline proficiencies with regards to writing explanation texts. The second was then aimed at strengthening the weaknesses I identified in my first cycle. Theoretically informed by the genre and socio-constructivism theories, and following the recommended stages of the genre pedagogy cycle, I designed a GBA lesson unit comprising seven lessons. The lessons spanned a two week period. I used formative assessment to assess my learners’ activities during each lesson using marking rubrics designed in line with the structural and linguistic conventions of explanation texts. Data sources include document evidence from my learners’ pre- and post- instruction written works, my written reflections on the teaching/learning process from my research journal, my learners’ written reflections on each lesson, and the whole class closing discussion. The data revealed that, prior to the GBA intervention, while my Grade 11 learners possessed some skill in writing shorter explanations for content subjects; they lacked deep knowledge for so doing in ESL. The post GBA intervention data revealed that, by interacting with texts and working collaboratively in unpacking the features of the genre, learners were able to develop a more critical awareness of the generic and linguistic features of written explanation texts. The study concludes that learners’ genre writing skills can be strengthened through using a GBA approach in which they are immersed in the relevant text features and provided with appropriate assistance and feedback.

The study aimed to improve my pedagogic practice in the teaching of genre as an English Second Language [ESL] teacher. It also aimed to further develop my Grade 11 learners’ academic language proficiency in genre writing. I employed two action research [AR] cycles. The first cycle was aimed at establishing learners’ baseline proficiencies with regards to writing explanation texts. The second was then aimed at strengthening the weaknesses I identified in my first cycle. Theoretically informed by the genre and socio-constructivism theories, and following the recommended stages of the genre pedagogy cycle, I designed a GBA lesson unit comprising seven lessons. The lessons spanned a two week period. I used formative assessment to assess my learners’ activities during each lesson using marking rubrics designed in line with the structural and linguistic conventions of explanation texts. Data sources include document evidence from my learners’ pre- and post- instruction written works, my written reflections on the teaching/learning process from my research journal, my learners’ written reflections on each lesson, and the whole class closing discussion. The data revealed that, prior to the GBA intervention, while my Grade 11 learners possessed some skill in writing shorter explanations for content subjects; they lacked deep knowledge for so doing in ESL. The post GBA intervention data revealed that, by interacting with texts and working collaboratively in unpacking the features of the genre, learners were able to develop a more critical awareness of the generic and linguistic features of written explanation texts. The study concludes that learners’ genre writing skills can be strengthened through using a GBA approach in which they are immersed in the relevant text features and provided with appropriate assistance and feedback.

- Description: Organic azides are important in the synthesis of many target molecules of great use in fine chemical and pharmaceutical production. The use of this class of compounds is however limited due to their hazardous nature and many safety concerns, as they are highly exothermic. Micro reactors can handle exotherms extremely well, due to the inherent high surface area to volume ratio, unlike the conventional batch process. This dissertation therefore aims to investigate the safe application of micro reactors in acyl azide chemistry.With this in mind, Chapter 1 provides a comprehensive background on organic azides, reaction calorimetric studies, flow chemistry technology (micro reactors) and their theoretical advantages. This chapter also discusses the preparation of organic azides in continuous flow systems and scaling up in continuous flow systems. Chapter 2 illustrates and discusses multivariate optimisation of benzoyl azide synthesis as a model reaction, synthesis of other acyl azides using the model reaction optimised conditions and multistep synthesis of carbamates, amides and amines in continuous flow systems via the Curtius rearrangement of benzoyl azide formed in situ from benzoyl chloride and sodium azide. The chapter also discusses process hazards analysis and evaluation of benzoyl azide synthesis and decomposition using calorimetric studies. It also investigates and discusses the effects of different mixing regimes and channel sizes on scale up. Chapter 3 has comprehensive experimental details for the whole dissertation with Chapter 4 providing the concluding remarks and future work recommendations.

Exploring and expanding situated cognition in teaching science concepts: the nexus of indigenous knowledge and Western modern science

- Description: Certain teaching and learning strategies are appropriate in the context of exposing learners to modern science in situated cognition (SC) - the theory that posits that knowing is inseparable from doing - during, for example, visits to industrial operations. The distance and cost of travel, however, excludes most rural teachers and their learners from such SC exposure to Science and technology in industrial settings. To fill this gap between knowledge and practice in the curriculum experience for rural schools, this research investigated the extent to which a SC approach could be used in relation to indigenous knowledge practices (IKP) that have relevance to science teaching for rural science teachers. The study was conducted in three schools in the Zambezi Region of Namibia whereby six science teachers participated in the study. Also, to generate data from the community, the study included Indigenous community members as participants. Only three selected members from the community participated as representatives of the whole community. Essentially, the study explored and expanded possibilities for rural school teachers to use IKP as sites of SC in relation to concepts of pressure in particular and other science concepts. The research thus studied teaching practices as activity systems related to concepts in the school curriculum and the activity system of Indigenous community members. The patterns, regularities and irregularities provided the framing which was used to view SC through the lens of IKP. This framing of SC within the school curriculum was explored using cultural historical activity theory (CHAT) and Engestrom’s expansive learning cycle (ELC). The study was organized into two phases; exploration and the expansive phase. In the exploration phase, interviews, community analysis, document analysis, brainstorming, reflections and audiovisual evidence were used to generate data. The expansive stage used brainstorming, reflections, and interviews, an experimental test, audio-visual evidence, and interviews. Inductive and abductive modes of inference were used to come up with explanations of the research questions. Explanations proceeded using the frameworks of socio-cultural theory and social realism. Some findings from the data generated from the exploration phase revealed that science teachers in the schools studied do not always engage in a SC approach on account of a lack of Western modern science (WMS) resources and factors related to economic marginalization of the learners. Data generated in the same phase revealed that science teachers can engage the SC approach through embracing indigenous knowledge practices (IKP) reflecting Science whereby they can apprentice learners. Some of the other findings from the expansive learning phase show that science teachers in under-resourced schools can engage the SC approach if IK practices are used as mediational tools which can be used as models, icons/symbols, vocabulary, patterns, case studies and practical activities anchored in IKP. From the findings obtained the contribution which the study made was to come up with some methods of infusing indigenous knowledge systems in science teaching. The trend in research related to IK is more aligned to policies rather than how IK can be usefully used for the benefit of science teaching. As the study only looked into the IKP reflecting Science which the participating teachers brainstormed, it provides an insight into how and which other IK practices can be woven into WMS to encourage social transformation accommodative of Afrocentric world views which allows scientific literacy to be achieved.

- Description: Education is a critical phenomenon which cannot be ignored as its effects cut across all spheres of life, especially the social and economic aspects. In the particular case of South Africa, education has been a serious issue of concern for a very long time and after the transition process took place in 1994 it became a priority on all agendas of governance. Expanding on the already existing debate about education in South Africa, this thesis specifically explores attitudes and perceptions about the knowledge acquisition process and experiences of Ngangelizwe youth graduates to understand the significance of education in their lives. As Freire wrote about the phenomenon of education from the point of view of the oppressed and marginalized in society, his theory explains and aids as a tool for careful analysis in this case. Moreover, considering that at the centre of Freire’s world view was the belief that humans have an ontological vocation to become more fully human, the youth graduates of Ngangelizwe became a good case as they live under conditions that one would regard as dehumanizing and oppressive. The youth graduates’ actions and attitudes would therefore guide and provide indication as to whether their education, both from academic spaces and the community, has empowered them to challenge the dehumanizing and oppressive nature of the dominant culture as a means to becoming fully human in their life and time, particularly in their community of Ngangelizwe. While the general finding has been that the participants’ education portrays both elements of banking and problem-posing education, it was also discovered that it all depends on the level and forces of education that the participants receive their inspiration from. This is due to the fact that education is not one dimensional, it begins from the moment one is born up until he or she no longer exists on earth. Therefore, education does not belong to one group of people; everyone has the ability to educate in as much as he or she has the ability to be educated.

- Description: In the past few decades, corporate crises have received high media attention and revealed the impact that a disaster can have on a company’s reputation. A breadth of scholarly literature has already analysed crisis communications and key elements of an effective response. In this study I examine crisis communications strategies of two companies (British Petroleum and Domino’s Pizza) who responded differently when faced with a crisis. The study will explore the companies’ actions and various media materials including public statements, press releases and social media platforms. This information will be presented alongside corresponding news coverage to reveal how the media translated these actions. Results show that by accepting responsibility and marketing efforts to stop the disaster, a corporation can transform its communication strategy and recover its reputation.

- Description: This aim of this study was to explore the mediatory role of the Rhodes University (RU) / Southern African Development Community (SADC) International Certificate in Environmental Education course in developing capacity for reflexive mainstreaming of environment and sustainability education in teacher education in southern Africa. This course was a change-oriented intervention to support capacity and agency for mainstreaming environmental education across many sectors of education. The discourse of the course included environmental education and education for sustainable development and for this study this was referred to as environment and sustainability education (ESE). Environment and sustainability education is a developing notion in southern Africa and the SADC Regional Environmental Education Programme (REEP) was set up to support capacity for mainstreaming ESE. ESE was one of the responses taken by the SADC region to respond to prevalent environment and sustainability issues across the region. This study focused, in general, on establishing the mediatory roles of the reflexive mediatory tool, the change project in the course. More specifically, the research explores the mediatory role of course interventions and activities that were used to develop understanding of and to frame the change project in fostering agentially motivated changed practice in the teacher education sector. Drawing on realist social theory, which is a form of critical realism, especially the work of Margaret Archer, the study used the principle of emergence to interpret changes in the course participants' practices. The study was framed using the research question: How do mediated actions in a regional professional development programme and the workplace influence Environment and Sustainability (ESE) competencies, practice, learning and agency in Teacher Education for Sustainable Development (TESD) change projects? The following sub-questions refined the study: • What mediated actions on the course influence ESE competences, practice, learning and agency on the professional development programme? • How do these identified mediated actions influence ESE competences, practice and learning on the professional development programme? • What mediated actions in workplaces influence ESE competences, practice, learning and agency in the change projects in teacher education institutions? • How do these identified mediated actions in workplaces influence ESE competences, practices and mediated actions in the workplace? Notions of practice, agency, reflexivity, competences and capabilities were used to sensitise explanations of features emergent from course interactions; the process of analysis was under-laboured by the theoretical lens of critical realism and realist social theory. Mediation theory was used to explain the role of interventions across the course. The study used a case study approach with three cases of teacher educators from two institutions in two southern African countries. Data were generated through document analysis of course portfolios, semi-structured interviews with research participants, observations of participants during their teaching and through group discussions in a change management workshop to establish features that emerged from the course and change project interactions. The principle of emergence recognises that any interactions result in new features of characteristics that are different from the original. In this case, the study investigated those features shown by participants after being exposed to the course's mediatory tools. In order to describe the cases, a narrative approach was used. The study was conducted at the interface of the United Nations Decade of Education for Sustainable Development (UNDESD) and the Global Action Plan for Education for Sustainable Development, therefore the outcomes have implications for capacity development for ESE during and beyond the Global Action Plan for Education for Sustainable Development. The key finding is that capacity development for ESE needs to foreground reflexive engagement with one's own practice for it to be meaningful and relevant. The change project provided course participants with the opportunity to engage with their own practice and particularly their competences and capabilities through its mediatory tools. Course participants showed emergent properties that were evidence of expanded zones of proximal development (ZPD) in competences, capabilities and agency. The study illustrates that meaningful learning happens when immersed in context and when learners are able to make connections between concepts, practices and experiences (their praxis). The study also illustrates that capacity building creates opportunities for practitioners to expand their repertoire through the course activities. Some of the course activities stimulated, enhanced and gave impetus to their agency or double morphogenesis for them to continue to expand that repertoire by trying and retrying changes in practice that they value on their own and in communities of practice. Capacity development courses need to be structured to involve a variety of mediatory activities as some of these are relevant and are valued for different teacher education contexts. The study also shows how knowledge and understanding of classical Vygotskian mediation can be used to frame and structure courses for developing the ZPD retrospectively and how the repertoire which forms the ZPD has potential to be expanded and to keep expanding, whether at individual level or in community with others, as an object in the post-Vygotskian mediation process. The change project provides the starting point, the vehicle and momentum to teacher educators to critique and to reflexively transform competences or aspects of their practice that they value. The study showed that capacity development through the change project generated momentum for potentially morphogenetic changes in teacher education practice. The course initiated interactions at the phase T2-T3 that disrupted teacher educators' habitus. On-course phase activities such as assignments, lectures, discussions, practical tasks, excursions and regional knowledge exchange groups contributed smaller morphogenetic cycles to the main cycle. Reflexive engagement with one's own practice becomes a useful tool for building capacity for scaling capacity for mainstreaming ESE during and after the Global Action programme for ESD. Contributions of the study therefore go beyond the SADC region to contribute insights into capacity development for ESD in similar conditions of teacher education across the world.

- Description: The purpose of this research was to explore counterfeit versus authentic luxury branded products from the perspective of consumers’ choice and social influence. Africa’s high level of domestic poverty has been one of the crucial factors for encouraging the import of counterfeit products (Meeking, 2013). In 2011, South Africa had estimated the counterfeit industry to be at R3.60 billion; and it is currently viewed as the world’s fastest growing industry (Le Cordeur, 2012; News24, 2011). Research on the purchases of counterfeit and authentic luxury brands has focused primarily on the supply side; however, this assumes that consumers are unaware of counterfeits. The aim was to explore whether consumers are able to distinguish between authentic and counterfeit products. In addition, the research also aimed to explore: 1) Youth consumers’ perceptions of luxury brands; 2) the attitudes of youth consumers towards counterfeit luxury brands; 3) the behaviour of youth consumers towards counterfeit products in general; and 4) the perceived influence of functional or status utility products on purchase behaviour. Therefore To methods of analysis was used; first a discrimination test was conducted and analysed using basic descriptive statistics were used. And second, a qualitative research methodology was adopted, from a social constructionist paradigm. Four focus-group interviews were conducted and analysed using thematic analysis. The results from the thematic analysis identified five themes, namely: 1) The conceptualisation of counterfeits; 2) conceptualising luxury brands; 3) attitudes towards counterfeit-branded products; 4) consumer decision-making styles; 5) status; and 6) post-purchase behaviour. This empirical study forms a foundation for future research on this phenomenon in the current context. Additionally, manufacturers should be aware of the impact of selling defect branded products on consumers’ conceptualisation of counterfeits. Marketers should also focus on the salient role of sneakers as status symbols among youth consumers.

The results from the thematic analysis identified five themes, namely: 1) The conceptualisation of counterfeits; 2) conceptualising luxury brands; 3) attitudes towards counterfeit-branded products; 4) consumer decision-making styles; 5) status; and 6) post-purchase behaviour. This empirical study forms a foundation for future research on this phenomenon in the current context. Additionally, manufacturers should be aware of the impact of selling defect branded products on consumers’ conceptualisation of counterfeits. Marketers should also focus on the salient role of sneakers as status symbols among youth consumers.

- Description: The study was conducted in order to determine the employee needs for an employee assistance programme in a welfare organisation in East London, Eastern Cape. This study was born out of a need from the management of this welfare organisation in East London who identified a need for an employee assistance Programme (EAP) within their organisation. According to management, there was a decline in productivity, and high stress levels due to high caseloads and societal demands (Leeuw, May 15, 2015). The theoretical framework that guided this research was systems theory. The rationale for using systems theory is that this study deals with individuals within an organisation who must coexist on a daily basis. There is a general belief that people and their physical-social-cultural environment interact in processes of mutual reciprocity and complementary exchanges (Merton, 2009). A qualitative approach was used in this study. Eight (8) employees from various levels in a welfare organisation were purposively selected to participate in the study. Semi-structured interviews were conducted with the participants and the interviews took more than forty-five (45) minutes each and this enabled the acquisition of rich information which is described in the findings and is used as a basis for the recommendations in the study. After the examination of the needs of employees for an EAP from the observations of both the employer and the employee it was clear that there is a need for employee assistance programmes in welfare organisations. Employees in this organisation are experiencing stress, burnout and were highly concerned about high caseloads that makes them feel incompetent to render adequate and quality services to their employees. The study also revealed that both employees and management of this organisation have different needs, experience different types of problems and view the EAP in different contexts. Despite the differences in their outlook on the situation, the evidence indicates that both employer and employee perceive that there is a need for an EAP, especially clinical services. At the same time, the issue of funding such a programme is also a concern. Recommendations were made for the organisation to develop an EAP to address the needs identified by employees, and for a clear communication strategy be developed to make all levels of employees within the organisation aware of the existence of such a programme. Another recommendation was made for the organisation to identify specific days on which they will conduct preventative awareness and debriefing sessions for the employees. It was also recommended that the South African Council for Social Services Professionals must standardise, regulate and monitor caseloads for the social work profession.

- Description: The aim of this study was to explore fathers’ role in supporting their children’s learning in selected urban primary schools in the East London Education District. Epstein parental involvement theory informed the study. The study was located in the interpretivist research paradigm and it qualitative in nature. It followed a case study research design. Participants were selected through the use of purposive sampling. A total of fifty two (52) participants were selected and these included school teachers, fathers and learners. Semi-structured interviews (for school teachers and fathers) and focus group interviews (for learners) were used in the four selected primary schools. The data was coded and thematic content analysis was used. The findings from the research indicated that fathers’ and teachers had a very limited understanding of fathers’ support in children’s learning. They generally thought that it was confined to activities done at school such as payment of school fees and levies, providing labour for the construction or renovation of school buildings and providing teaching/learning resources. Participants confirmed that the majority of fathers were too poor and with low education to be meaningfully involved in their children’s learning. However, there were a few fathers who believed that their socio-economic status did not prevent them from participating in their children’s learning. They actually indicated useful ways in which they could be involved. It was found that a minority group of fathers who were unemployed spent time helping their children in their learning whilst, those working worked long hours and had no time to help their children. Among the significant findings of the study was the fact that educated fathers were too involved in their children’s learning and even reserved time on weekend to be part of their children’s life and learning. The research also revealed that fathers and teachers had wrong perceptions about themselves and each other in connection with limited fathers’ support in their schools. The study recommends, among other issues, enhanced school/parent partnership with emphasis on the involvement of fathers in academic activities meant to improve their children’s learning.

- Description: Limited resources, extreme temperatures and predators are some of the stresses that are faced by ungulates in arid biomes. Understanding how these stressors influence ungulate feeding ecology and population growth rates is important for managers, as these could influence the persistence of ungulates in protected areas. An understanding of these stressors is especially relevant given the significant population declines in ungulate species globally. The Nama Karoo biome and the arid Savanna, an arid form of the Savanna biome, are both arid, but have distinct rainfall seasonality and vegetation structure and represent unique characteristics that need to be properly considered in their own regard. The literature on African ungulate feeding ecology covers a range of species and biomes from southern and east Africa, however, very little is known about ungulate dietary preferences in the Nama Karoo. Unexplained population declines in springbok (Antidorcas marsupialis) and red hartebeest (Alcelaphus buselaphus caama) have occurred at local scales across the Nama Karoo and the arid Savanna, most notably springbok population declines at the Karoo National Park (Karoo NP). This study sought to improve the understanding of ungulate feeding ecology and population growth rate responses in two arid biomes of South Africa. To achieve this, ungulate dietary composition was characterised, in terms of the proportional seasonal contribution of C4 and C3 plant forms, of a range of ungulates in the Nama Karoo, at the Karoo NP and the arid Savanna, at the Tswalu Kalahari Reserve (Tswalu KR), using stable carbon isotope analysis. Fresh faecal samples of ungulate species were collected from both the biomes during the dry, early wet and late wet seasons. Species were categorised per biome into feeding guilds and the effects of season, biome and the interaction thereof on the diets of the ungulate species explored. Furthermore, the findings were interpreted against what is known about diets of the respective species elsewhere in southern and east Africa. Secondly, trends in ungulate population growth rates were assessed within the Karoo NP and the Tswalu KR over the past 12 and14 years respectively. Furthermore, the variables influencing ungulate population growth rates (and generality of trends), with emphasis on ungulate biomass and rainfall, were explored at biome and species level. Population size data were obtained from annual aerial censuses for the period 2002-2015 and used to calculate annual growth rates and biomass for each ungulate species. The contribution of C4 forage to the diets of ungulate species in the arid Savanna was generally higher than in the Nama Karoo,in line with greater relative abundance of C4 grasses in the former. During winter (dry season) C3 intake was higher in the Nama Karoo than in the arid Savanna, reflecting C3 plant growth (C3 grasses and shrubs) and rainfall during winter in the Nama Karoo. Mean population growth rates during the study period were negative in some of the threatened species considered, i.e. mountain reedbuck (Redunca fulvorufula fulvorufula), tsessebe (Damaliscus lunatus lunatus) and Hartmann’s mountain zebra (Equus zebra hartmannae). No evidence for negative density dependent regulation (~intra-/interspecific competition) of ungulate population growth rates was found, whereas bottom up (~rainfall) and positive density dependent (~biomass of the species under investigation) regulatory mechanisms were most influential. The rainfall and biomass variables influenced the population growth rates of smaller ungulate species more than those of larger bodied ungulate species. Knowledge of ungulate diets will enable managers of protected areas to better understand how climate change, and resultant changes in relative abundances of plant growth forms, will influence specific ungulate species. The finding that increased population biomass positively influenced certain ungulate species’ growth rates has potential implications for management intervention as ungulate biomass is a variable that can be manipulated in protected areas. The reinforcement of existing mountain reedbuck, springbok and red hartebeest populations, specifically, at the Karoo NP and the Tswalu KR may counter their current negative growth rates in these two protected areas. Finally, the influence of protected area size and fencing, on ungulate vulnerability to predators (~top down) and forage quality (~bottom up) mechanisms in arid biomes needs to be further explored.

- Description: The Namibian Senior Secondary Certificate Examiners’ Reports (2013) shed light on the topics in which learners often perform poorly and evolution is one of such problematic topics. Anecdotal reasons include religious views of teachers, opposition by learners to the topic, and inadequate understanding of the subject content knowledge. I have not come across any literature on evolution in Namibia that formally look closely at this problem. We do not have a clear idea of what is going on in Namibian science classrooms, when evolution is taught. We do not have a clear idea of the factors at play in the teaching of evolution in these classrooms, either when it is done well and completely or when it is not so. It is against this background that I was inspired to engage in this study which examined teachers’ conceptions, dispositions and pedagogical strategies that they use when teaching evolution. The study is underpinned by an interpretive paradigm, which afforded me an opportunity to understand the teachers’ worldviews in relation to evolution. It also allowed me to gain insight on the pedagogical strategies that teachers use when mediating learning of the topic of evolution and its related concepts. Within the interpretive paradigm, a case study approach was adopted, using a mixed-method design generating both quantitative and qualitative data. Teachers from two regions, namely, the Hardap region and Khomas region, participated in the study. Data were generated using questionnaires, semi-structured interviews and lesson observations. Fifteen questionnaires were completed and from those questionnaires, the sample included six teachers (40%) from the Hardap region while nine teachers (60%) were from the Khomas region. For the interview, the sample included two teachers - one from each region. For the observations, I observed five teachers teaching evolution. I presented quantitative data in tables and graphs, whereas the qualitative data was analysed inductively using Vygotsky’s (1978) socio-cultural theory as a theoretical framework. In addition, I used Ogunniyi’s (2006) Contiguity Argumentative Theory (CAT) as an analytical framework. These theories were used as lenses to interpret and make sense of the qualitative data, which I colour coded to form sub-themes. Thereafter, overlapping sub-themes were combined to form themes, which were linked to the research questions and in relation to literature/theory. Similarly, overlapping themes were combined to form analytical statements. It emerged from the study that religious views did not play a large role in most teachers’ views and attitudes towards the teaching of evolution. Instead, it emerged that lack of content knowledge on evolution is the main factor that influences teachers’ views and attitudes towards teaching evolution in schools. This is quite profound, as the assumption is that when teachers are religious, the likelihood is that they would object to the teaching of evolution. In light of this, the study recommends that there is a need for professional development and support of science teachers, so that they are able to properly mediate the learning of evolution.

- Description: There is extensive research on the fact that the learning of science is assisted through the inclusion of the prior everyday knowledge and local knowledge that learners bring from home and from within their communities. It is precisely for this reason that the Namibian Learner Centered Education (LCE) curriculum encourages teachers to include learners’ prior everyday knowledge in their science lessons. However, the inclusion of traditional knowledge/local knowledge or indigenous knowledge (IK) and how this should be done has been largely ignored both in the Namibian school science curriculum and textbooks. It is against this background that this study sought to explore teachers’ views and experiences on the inclusion of IK in Physical Science Grade 9 lessons as well as the pedagogical strategies that they use. This research used a mixed methods approach (quantitative and qualitative data were collected) which was underpinned by the interpretive paradigm. Within the interpretive paradigm, I employed a case study approach. The study was carried out in the Endola education circuit of the Ohangwena Region. Essentially, the study explored three things: Firstly, the views, experiences and pedagogical strategies of Grade 9 Physical Science teachers on the inclusion of indigenous knowledge in their lessons. Secondly, to find out what factors enable the teachers to integrate their local knowledge into Physical Science lessons? Thirdly, to look at constraints that affect Grade 9 Physical Science teachers in the use of local knowledge in their science lessons. Data were collected using questionnaires and semi-structured interviews. The data obtained were validated in two ways, firstly, the data were triangulated from different data gathering techniques, and secondly, validation was done by member checking of the transcribed scripts. To make meaning from the data generated, Vygotsky’s (1978) socio-cultural theory was used as a lens to analyze the data. The data generated were coded inductively and presented in graphs, tables and descriptive texts to make meaning. The findings from the research revealed that teachers in the Endola circuit do make some efforts to include indigenous knowledge in their lessons. Furthermore, teachers seemed to grasp the benefits and constraints that come with the inclusion of indigenous knowledge in their science lessons. For example, it emerged that indigenous knowledge enables learners to link what they are taught in the science classroom to what is happening in the community or at home, thereby enhancing their understanding of the concepts. Topics such as acids and bases, friction, combustion, static electricity and pressure emerged as some of the topics in which teachers include indigenous knowledge. On the other hand, the issue of language, textbooks and lack of indigenous knowledge by teachers affects the way teachers are able to include IK in their lessons. This study thus recommends that teachers should explore different indigenous practices that can be linked to the topics in the curriculum or syllabus to enhance learning and teaching. Furthermore, they need to involve local communities that possess indigenous knowledge to help in delivering indigenous practices during the lessons. Lastly, teachers and communities should start developing learning and teaching support materials that are useful when local knowledge is included.

- Description: The aim of this study was to explore and describe HIV and AIDS workplace programmes and policies (WPPs) in the tourism industry of Nelson Mandela Bay Municipality (NMBM) in South Africa. This study adopted a quantitative and qualitative approach, in other words, a mixed approach. The reason for using more than one method of inquiry was to obtain a deeper understanding of the tourism industry of NMBM in terms of examined behaviour, and of the meaning of occurrences in the industry. To gather qualitative data concerning HIV and AIDS programmes, key informant stakeholders in the tourism industry at global, national, provincial, and local levels were identified to conduct in-depth interviews. These respondents were selected using the non-probability sampling method of quota sampling. This is a type of stratified sampling in which the selection of the strata within the sample is not random, but rather is typically left to the discretion of the interviewer (Wienclaw, 2015). One respondent for each level of the industry was selected, resulting in four key informant stakeholders participating in the qualitative research component of this study. The initial criterion for participation in the quantitative portion for this study was that tourism businesses based in NMBM must be able to produce robust evidence of HIV and AIDS WPPs. The researcher selected the probability sampling method of stratified random sampling with proportional allocation. This technique considers the known characteristics of the population (Wienclaw, 2015). A database of tourism businesses was obtained from the local tourism organisation, who are members of the governing body for local tourism. This database was cleaned, to eliminate any data that did not meet the participation criterion for the study. Ten per cent of the total number of businesses in the cleaned database were sampled. The simplest approach to sampling is to merely randomly select from the population by, for example, having a computer choose names at random from a list, or by selecting names from a hat (Wienclaw, 2015). Therefore, every fifth business listed on the sampled database was selected to participate. Unfortunately, surveys tend to have notoriously low return rates, and people are frequently reluctant to give out information over the phone. This was also the case for most of the tourism businesses in the sample. When emailed or telephoned, they refused to participate for various reasons. Some stated that HIV does not affect their business; others reported that their businesses were too small and therefore they could not afford to implement these programmes. Some businesses were hearing about the WPP for the very first time, while several others responded with simple disinterest in participating. The findings of the study are that although tourism is viewed as an important industry that contributes to the economy, tourism businesses do not include any intervention programmes with which to respond to the threat of HIV and AIDS to their businesses. Additionally, there is neither leadership nor support from any level of the tourism industry, to create a conducive environment for the adoption of HIV and AIDS WPPs by tourism businesses. The primary reason for the lack of uptake of these programmes is ignorance across cascading levels of the tourism industry, which includes tourism businesses. Additionally, a number of perceived barriers, such as size of business, are cited as the reasons why tourism workplaces in the NMBM fail to participate in HIV and AIDS WPPs. It is anticipated that this study will create further awareness of HIV and AIDS WPPs, in an industry that seems to have limited knowledge about such programmes. This study will also provide guidance regarding the requirements to implement effective HIV and AIDS WPPs.

- Description: The aim of this study was to explore and describe HIV and AIDS workplace programmes and policies (WPPs) in the tourism industry of Nelson Mandela Bay Municipality (NMBM) in South Africa. This study adopted a quantitative and qualitative approach, in other words, a mixed approach. The reason for using more than one method of inquiry was to obtain a deeper understanding of the tourism industry of NMBM in terms of examined behaviour, and of the meaning of occurrences in the industry. To gather qualitative data concerning HIV and AIDS programmes, key informant stakeholders in the tourism industry at global, national, provincial, and local levels were identified to conduct in-depth interviews. These respondents were selected using the non-probability sampling method of quota sampling. This is a type of stratified sampling in which the selection of the strata within the sample is not random, but rather is typically left to the discretion of the interviewer (Wienclaw, 2015). One respondent for each level of the industry was selected, resulting in four key informant stakeholders participating in the qualitative research component of this study. The initial criterion for participation in the quantitative portion for this study was that tourism businesses based in NMBM must be able to produce robust evidence of HIV and AIDS WPPs. The researcher selected the probability sampling method of stratified random sampling with proportional allocation. This technique considers the known characteristics of the population (Wienclaw, 2015). A database of tourism businesses was obtained from the local tourism organisation, who are members of the governing body for local tourism. This database was cleaned, to eliminate any data that did not meet the participation criterion for the study. Ten per cent of the total number of businesses in the cleaned database were sampled.

- Description: It has been observed that the teaching and learning of the concept of rates of reactions is seen as being difficult for most Namibian learners. Concerns have been expressed in Examiners’ Reports about candidates showing little knowledge of the topic ‘rates of reactions’. Hence, this study sought to explore how indigenous knowledge and practices through a practical activity of making oshikundu, enabled or constrained learner-engagement and sense-making of the concept of rates of reactions in Namibian schools. Underpinned by an interpretive paradigm, the study tried to describe and understand how learners make sense of their world. Within the interpretive paradigm, a mixed-method case study approach was adopted. It is informed by Vygotsky’s socio-cultural theory, which recognises that learning and meaning-making are represented as originating from social interactions among individuals. The research study was conducted in a rural secondary school in the northern part of Namibia with Grade 11 Physical Science learners. Purposive sampling techniques were used to select three learners from the class, as the interview sample. A pre-test was used to gather data on the type of prior knowledge that Grade 11 Physical Science learners had of concepts related to rates of reactions. The pre-test’s content was validated by two Physical Science specialists. Observations were used to explore how learners make sense of rates of reactions during lessons. In addition to observations, interviews and a post-test were used in order to gather data on how the practical activity of making oshikundu enabled or constrained Grade 11 Physical Science: (a) learner engagement and (b) sense-making of the concept of rates of reactions. The findings of the study found that learners were more engaged and participated more fully in class than in previous year when the indigenous practice of making oshikundu was incorporated during the science lessons. The study thus recommends that indigenous knowledge and practices be integrated into Physical Science classrooms for effective teaching and learning and sense making of science concepts.
