- Description: __iFogSim is a toolkit to model, simulate and evaluate networks of Fog computing, Edge computing and Internet of Things (IoT). This framework provides the capabilities of analysing and evaluating the performance of applications and resource management policies in Fog/IoT environments, based on which designers can model and test their applications. This thesis proposes a novel application model of a traffic surveillance vehicular network application through smart cameras using iFogSim, where the scenario of multiple vehicles tracking is considered. The effectiveness of the proposed application model is assessed and validated by simulations using a modified application model inherited from a case study of intelligent surveillance through distributed camera networks introduced. Simulations are conducted using the iFogSim tool and performance evaluation is done. The comparison between one vehicle and multiple vehicle tracking is done and the results demonstrate that the multiple vehicle application model achieves a better performance in terms of average latency and data transfer rate

- Description: The study seeks to assess and examine the management and implementation of the code of conduct by the Eastern Cape Department of Basic Education in addressing service delivery in the Province. The reason for the Researcher to undertake the study is influenced among others by poor of service delivery, maladministration and corruption reported in this department through media, newspapers, Auditor General (AG) Reports and Portfolio Committee on Basic Education Eastern Cape Legislature which act as the oversight mechanism for this department. Literature review was conducted as a secondary source of information and primary information was conducted through sample of 30 respondents which were selected by the Researcher. The respondents were from the most key units of the department of Education Eastern Cape, which are stated in chapter one of the study. The study followed qualitative research approach which included semi-structured questionnaire, observation and document analysis. The findings of the study indicate lack of management and implementation of the code of conduct by the department. They clearly shows, lack of awareness and understanding of the code itself by the general staff members, lack of discipline, poor employee attitude, and unwillingness to improve service delivery and corruption in the department systems. The findings of the study expose lack of understanding of the code of conduct by the civil servants in the Department of Education, Eastern Cape. This can be attributed to lack of induction, orientation and training, in order to understand the importance of the code of conduct. Document analysis revealed that, there was lack of adherence and observation of the department’s established policies, rules, regulations, procedures and flouting of supply chain management processes and corruption in the system which is tantamount to violation of the DPSA code of conduct. These factors all contributed to this department’s failure in achieving clean audit outcomes from the AG during the last term. Department of Basic Education, Eastern Cape Province, received qualified and adverse audit reports between 2009 and 2014 financial years. The study recommends trainings of the department of education officials in the DPSA code of conduct. More vigorous on going ethical training is very crucial in the attempt to promote ethical behaviour, to root out corruption, under performance and vi maladministration activities experienced in this department so as to fast track service delivery to the people of the Province, in the following terms of Government administration going forward.

- Description: The aim of the study is to explore the role of social work intervention in empowering victims of crime in the Alice community. The study used a qualitative research design to collect data from nineteen (19) participants. The findings revealed that people living in rural areas are vulnerable because they do not get the necessary support from the government, social workers and other professional bodies. Yet the role played by social workers to assist victims of crime is not enough because they are few and they do not have enough resources to execute their work. The study reveals that most of the victims of crime were females, others were employed and few of them were unemployed. The study recommends that policy makers need to evaluate the overall impact of different criminal activities by measuring the extent to which dependence changes as policies are changed. Debates should be centred on a discussion of how to design better programs in order to achieve the developmental objectives since it is evident that criminal activities grow day-by-day in South Africa. The study concludes that the researcher hopes that the objectives were adequately handled as they attempted as much as possible to address the possible implications associated with victimisation.

- Description: The National Health Insurance is a relatively new concept in South Africa currently being piloted to ensure that all citizens have access to quality and affordable health care regardless of their socio-economic status. This study was prompted by concerns regarding the introduction of the NHI and its implications on the South African health system. Therefore it seeks to determine the professional nurses concerns about the introduction of the NHI in a private hospital in Gauteng and to describe recommendations based on these perceptions. This study used a qualitative, exploratory and descriptive design. Data was collected using a semi-structured individual interview schedule. The sample was purposive consisting of professional nurses employed in a private hospital in Gauteng. Thematic data saturation determined the number of professional nurses interviewed. Data analysis was done with the aid of Creswell’s theory (2014:1996). Ethical considerations were observed and trustworthiness maintained. The results of the study outlined that professional nurse’s perception about the NHI is centred on equal distribution of health services to benefit all South Africans. However, concerns were based on its financial implications for those mandated to pay towards the fund. The feasibility of its implementation in the midst of staff shortage, inadequate resources and its impact on the public health sector was seen as a major challenge. The notion of a joint effort between public and private health sector in creating one health system was anticipated by most participants. The NHI implementation raised concerns about the impact it will have on the private sectors viability in the future. Professional nurse’s non-involvement in policy making, poor communication, lack of transparency, concerns about governance and management were perceived to be stumbling blocks towards efficient and effective implementation of the NHI.

- Description: This study investigates the making of a Student-Resource Centre in Central, Port Elizabeth. The project evolved from the situation in Central, where there is an increase in the student demographic, due to the increase in registered students at the Nelson Mandela Metropolitan University (NMMU). This has resulted in a shortage of student housing on campus; and therefore many students are living in the inner city where housing is more affordable but transport to campus is still accessible. These students are decentralised from the main University Campus; and they do not share the same 24-hour access to NMMU facilities, as do those living on-campus, or in Summerstrand. This treatise proposes a student resource centre within Central, located near the highest density of students, to provide study facilities, off-campus student health services, off-campus computer facil-ities, student-connection spaces, as well as a link to the broader community through student-oriented retail/commercial facilities, such as printing/copy centres, food markets, laundry facilities et al., as well as providing additional student accommoda¬tion in the form of student flats. The primary design aim of this treatise, is to design a student resource centre that provides the decen¬tralised students in the inner city with equal access to the same standard of facilities as the students that reside on-campus and within the more expen¬sive area of Summerstrand, through the study and implementation of contemporary learning space theories that are relevant to the 21st Century Stu¬dent. Qualitative research methodologies were used, using both primary and secondary sources, in the methods, as laid out herein.

- Description: Severe land degradation associated with current conventional production systems have resulted in low production amongst the small scale farmers in the Eastern Cape. Inappropriate management practices cause depletion of organic matter and other essential nutrients leading to a decline in crop productivity. There is growing evidence that conservation agriculture (CA) practices involving no-tillage (NT) coupled with crop rotation and surface residue retention increases soil organic carbon (SOC) and other essential nutrients and therefore has potential to alleviate soil quality deterioration. A study was carried out to investigate the effects of tillage and crop rotation with crop residue retention on selected soil properties and on wheat yield in the Alice Jozini ecotope of the Eastern Cape. Specific objectives were to determine (i) the effect of crop rotation and tillage on soil SOC, NH4, NO3, total N, P, K, Ca, Mg, Zn, soil pH and EC distribution at 0-5 cm, 5 cm -10 cm, 10 cm-20 cm (ii) the effect of crop rotation and tillage on soil bulk density, porosity and on soil water content (iii) the effect of crop rotation and tillage on wheat biomass and grain yield. Treatments were arranged as a split-split plot in a randomized complete block design with three replicates. Tillage treatments included no-tillage (NT) and conventional tillage (CT) and were applied on the main plots while crop rotation treatments were applied as subplots. Crop residue retention treatments were applied as sub-sub plots. The rotational treatments were maize-fallow-maize (MFM), maize-fallow-soybean (MFS), maize-wheat-maize (MWM) and maize-wheat-soybean (MWS). However, the current study focused on tillage and crop rotation treatments under residue retention to give 8 treatments. Data from the field trials showed that NT with residue retention had significantly (p < 0.05) higher SOC, Total N, P, K, Ca and EC relative to CT. The MWS rotation under no-tillage (NT) with residue retention followed by MFS resulted in the progressive improvement in soil nutrient status. The correlations of SOC with various soil nutrients under study showed that the nature of the relationships between SOC and nutrient availability was consistent. Results on soil physical parameters showed that tillage had no significant effect (p > 0.05) on soil bulk density (ρb) and porosity whereas a significant effect on soil water content under NT was observed. Crop rotation had no significant effects (p > 0.05) on soil bulk density, porosity and soil moisture across the tillage treatments. The MWS rotation registered an increase in soil porosity in comparison with the MWM and MFM. Tillage x crop rotation interaction effects were significant (p < 0.05) on the measured porosity and soil water content. Soil bulk density showed negative correlation with soil porosity and soil water content (SWC) whereas porosity had a positive correlation with SWC. On yield parameters, results revealed that no significant (P>0.05) interaction of main effects with respect to wheat biomass and grain yield. Tillage had a significant (P<0.05) effect on wheat biomass only in season 2. Tillage and crop rotation effects were not significant (P>0.05) with regards to grain yield throughout the experimental period. Higher grain wheat biomass and grain yield were found in MWS rotation under NT with surface residue retention although not statistically significant. Correlation analysis revealed that wheat yield was positively correlated to SOC, P, and Total N. Therefore, combination of NT with MWS rotation with residue retention has the potential to significantly improve soil chemical properties and wheat grain yield whereas MWM followed by MWS crop rotation under NT showed an increase in soil porosity and soil water content.

- Description: The post-1994 democratic dispensation was presented with a challenge of how to improve equity of access for the incoming Black majority in institutions of higher learning (Cloete and Moja, 2005; Badat, 2010). Democratization of access to institutions of higher learning led to what has been called a “revolution” in the student demographics of higher education institutions in South Africa (Cloete and Moja, 2005). Many of the new entrants, particularly those entering historically white institutions, are from working backgrounds and are the first in their families to have the opportunity obtain a tertiary qualification – they are ‘first generation’ students. This thesis is interested in the experiences of first-generation working class students as they negotiate the terrain of an elite, historically white, South African university. While a prior body of research on first-generation students has focused primarily on the educational, cultural and economic deficits and challenges that these students experience, the present project was interested in the question of social capital in relation to these students. The thesis set out to explore what social networks these students do and do not have access to, and the various ways that they create, access and take advantage of alternative social networks in order to overcome their marginality in their everyday lived experiences at the university. In depth qualitative interviews with 31 participants were employed to gain an insight into the experiences of first-generation Black working class students at one university. The study finds that while first-generation students are not bereft of social capital, their networks are often inward-looking, based as they are on mutual recognition of markers of marginalisation and poverty which risks restricting these students to the margins of university life.

- Description: ICTs have had a tremendous impact on our educational environment. There have been a huge number of developments and support in implementation of ICT in Higher Education teaching and learning, also referred to as e-learning. Similarly there appears to be quite a number of research conducted on the use of ICTs in blended learning settings worldwide and as well as in South Africa. Very little research however, has focussed on the experiences of lecturers with e-learning, specifically as it relates to Learning Management Systems (LMS). In trying to meet the requirements of its academic programmes and be in line with new developments worldwide, the University which is the focus of this study pilot projected the use of an LMS in a blended learning approach which integrates face-to-face classes with Blackboard, an ICT-based system or tool. Following the implementation of the pilot project, this study explores the experiences of lecturers in their blended learning environments at this university in the Eastern Cape province of South Africa. The research design was that of an interpretative paradigm within a qualitative research approach in a case study methodology. Purposive sampling of six lecturers from departments within faculties across two campuses was done. The data was gathered through interviews, a follow-up questionnaire and document analysis was employed. Using Critical and Social Realism as meta-theories the study employed aspects of Activity Theory as substantive theory to understand particular experiences of blended learning environments and identify conditions which enable and constrain engagement in these environments so as to explore potential lessons to inform the kind of educational support which could be offered to facilitate uptake of the LMS.

- Description: The accountability and responsibilities of school leaders have intensified greatly over the past decades and school leadership has become a strong focus of research. Meanwhile, Bush (2003) asserts that “school leaders [experience] tensions between competing elements of leadership, management and administration” (p. 7). This study uses observations, questionnaires, interviews and document analysis to unpack the perceptions of four Heads of Department (HoDs), the principal, and eight teachers on the tensions inherent in balancing the responsibilities of department head and subject teacher for HoDs in public secondary school. The study goes beyond the mere task of influence in its attempts to unpack how the leadership and teaching practices of HoDs may, or may not, be in conflict with each other. Using distributed leadership as a theoretical framing and drawing in particular on the work of Spillane and colleagues (2001; 2004), the study examines the roles HoDs enact; the challenges HoDs encounter in enacting their responsibilities as department head and subject teacher; and the strategies HoDs employ to combat the emerging challenges. The study found that the roles of HoDs are extensive and stretch across the classroom, the department, the whole school and beyond. However, the majority of these roles are biased in favour of management systems and processes and opportunities for leadership are rare. The many and extensive management responsibilities of the HoDs limit both their classroom teaching as well as their agency as leaders. The weight of their management work thus restricts their leadership, resulting in an authorised form of distributed leadership (Grant, 2010). The data also revealed that HoDs struggle to balance the responsibilities of department head and subject teacher due to both inter-role and intra-sender conflict. However, the study also found that the HoDs strategically adopt a range of strategies to assist them in doing their work, these include: compensatory teaching; delegation; and planning and prioritizing.

- Description: This study sought to explore strategies used to elicit a reading culture among secondary schools learners. The importance of reading cannot be over emphasised as it is used as an index to how well an education system is, in the delivering of its mandate of creating a reading nation. In view of this, the South African government has developed a range of legislation and policies that shape reading and literacy in the country. Theoretically, the study is built around the socio-cultural theory which is conceptualised by different reading models. Methodologically, it is premised within the interpretive paradigm based on a case study design. In view of this, the study made use of the Qualitative research method with the principal tools for data collection being; interviews, focus group discussion and, observation. The main findings of the study revealed that using English as the medium of instruction in South Africa is not such a good idea. In this regards, teachers need some form of training to cope with the use of English (a first additional language to both teachers and learners) is a problem in itself. The study recommends that the government needs a) to provide funding to ascertain that resources needed to facilitate reading are available, b) the government should also play the role of monitoring and evaluation to make sure that the policies are kept in place and, c) There is need for in-service training for teachers to make sure that they are living up to expectation. There would be tremendous growth in socio-economic terms with a love for reading being fostered among all members of the school and community.

- Description: Single-parent households are on the increase in our society and especially single-father households where fathers are fulfilling the role of both parents in rearing their children. In this qualitative study, three single fathers who are primary caregivers were interviewed regarding their experience of primary caregiving, adjusting and coping with the transition to primary caregiving and their needs and concerns for their children's future. This study utilised a phenomenological approach to look at single fathers as the best and most informed individuals to explore and describe their lived experiences of being primary caregivers. The rationale for using interpretive phenomenological analysis (IPA) is that it is concerned with individuals' subjective reports and assumes that participants seek to interpret their experiences into some form that is understandable to them. The researcher utilised three semi-structured, in depth, face-to-face interviews as a method of data collection. Each interview focused on eliciting different sets of data, firstly the researcher look at identifying the participants' experience of primary care giving, then moved onto their adjusting and coping with the transition and finally focused on the primary needs and concerns of participants with regards to primary care giving. The sub-themes that emerged from the study include the loss of a partner, shifts in the role the fathers play as parent, dealing with children's reaction to the "loss" of a mother in the home, good parenting: biology vs upbringing, social construction of men and woman, the value of self-care for single fathers, where self-care incorporates both physical and mental care, internal support from family or friends, external support from the community, relationship between fathers and children and sibling relationships. These led to the various super-ordinate themes. The super-ordinate themes and categories that resulted from the analysis of the material include: (1) The transition to being a single-parent and primary caregiver was difficult, (2) Parenting is not biological it is cultural and fathers can fulfil the role, (3) Self-care is important, (4) Support comes from family and friends but social support is rare, (5) Close family relationships are formed

- Description: This study investigated the relationship between job engagement and locus of control on the one hand, and organisational citizenship behaviour on the other among non-academic and academic employees of the University of Fort Hare. Job engagement and locus of control were the independent variables and organisational citizenship behaviour was the dependent variable. Data was drawn from a sample of 300 participants. A questionnaire was used to collect the data. It consisted of four sections including biographical and occupation data questionnaire. To measure job engagement, the 18-item Rich et al., (2010) job engagement scale, with a 5-point Likert scale was used. To measure locus of control, the 16-item Spector (1988) work locus of control scale was used, with 6-point Likert scale. To measure organisational citizenship behaviour, the Fox & Spector (2011) 20 item organisational citizenship behaviour questionnaire, with a 5-point Likert scale was used. Data was analysed using various statistical techniques including the Pearson Product Moment Correlation Technique and the generalised linear regression model. The results indicated that job engagement has a significant positive correlation with organisational citizenship behaviour and locus of control also has a significant positive correlation with organisational citizenship behaviour. However the results also indicated that when job engagement and locus of control are put together, they do not account for a significantly higher proportion of variance in organisational citizenship behaviour than each of them separately. Furthermore, as far as OCB-P and OCB-O are concerned, the results indicated a partial support of the research hypothesis that job engagement and locus of control together account for a significantly higher proportion of variance in organisational citizenship behaviour than any of the two separately. The study recommends that managers in organisations must focus on improving job engagement and promoting internal locus of control in order to ensure high levels of organisational citizenship behaviour.

Modelling stock return volatility dynamics in selected African markets

- Description: Stock return volatility has been shown to occasionally exhibit discrete structural shifts. These shifts are particularly evident in the transition from ‘normal’ to crisis periods, and tend to be more pronounced in developing markets. This study aims to establish whether accounting for structural changes in the conditional variance process, through the use of Markov-switching models, improves estimates and forecasts of stock return volatility over those of the more conventional single-state (G)ARCH models, within and across selected African markets for the period 2002-2012. In the univariate portion of the study, the performances of various Markov-switching models are tested against a single-state benchmark model through the use of in-sample goodness-of-fit and predictive ability measures. In the multivariate context, the single-state and Markov-switching models are comparatively assessed according to their usefulness in constructing optimal stock portfolios. It is found that, even after accounting for structural breaks in the conditional variance process, conventional GARCH effects remain important to capturing the heteroscedasticity evident in the data. However, those univariate models which include a GARCH term are shown to perform comparatively poorly when used for forecasting purposes. Additionally, in the multivariate study, the use of Markov-switching variance-covariance estimates improves risk-adjusted portfolio returns when compared to portfolios that are constructed using the more conventional single-state models. While there is evidence that the use of some Markov-switching models can result in better forecasts and higher risk-adjusted returns than those models which include GARCH effects, the inability of the simpler Markov-switching models to fully capture the heteroscedasticity in the data remains problematic.

- Description: This study reviews a training programme on Marine Protected Area (MPA) management. It notes that although MPAs are well promulgated under legislation, reports have found that there are still key challenges facing the management of these areas. The research examines how the course was developed following the Lemm and Attwood (2003) report and designed to develop competences for effective MPA management. The aim is to identify how a MPA management training course produced competences apposite to the workplace settings of the participants. An interpretive case study method was used, in two phases. The first phase explored salient issues in MPA management in South Africa through analysis of the two key ‘state of MPA management’ reports and interviews with MPA professionals. The second was an analysis of the South African Marine Protected Area Management Training Course. This involved interviews with course designers, a review of the course materials, interviews with past course participants, and an analysis of course evaluations. Evidence emerged that supported the following findings: Challenges and problems facing MPA management still exist. Competence in key areas of MPA management was addressed in an effective work-integrated approach. Social learning was a key process in the development of these competences. The competences articulate well with the workplace of participants. Gaps exist between some of the management issues and the competences developed by the course, and some aspects of the course design are ineffective. From these findings it is concluded that: The course took up the majority of issues in MPA management through the development of key competences. The course design facilitated the development of these competences. The competences developed through the course are relevant to the workplace of MPA professionals. The research found that the course adequately addresses issues in MPA management through the development of competences. Some recommendations for improvements are made.

- Description: The changing global and local circumstances and shift for democracy posed particular problems for school administration and leadership and made it difficult for principals to fulfil leadership responsibilities in schools alone. Hence principals require the assistance of all stakeholders in the school, and teachers in particular, to work together as a team and share the diverse leadership load for the improvement of schools. Thus, leadership in schools needs to be shared and distributed in a collaborative manner among teachers and principals working as a group to accomplish the primary objective of their schools, which is to improve learners’ achievement. For this idea to be embraced, I suggest it may require an urgent need for advanced knowledge and understanding of teacher leadership in schools, among teachers and principals, if schools are to thrive. This research studied the phenomenon of teacher leadership at a public rural school in the Ohangwena region of Namibia. It explored the teachers’ experiences of their leadership roles, and specifically the challenges inherent within the practice of teacher leadership in a school. A qualitative interpretive case study was conducted, employing document analysis, semi‐structured interviews and observations to produce data with regard to teachers’ experiences of their leadership roles, challenges inherent within its practice and possible strategies to promote teacher leadership. The analysis and the triangulation across the data sets suggested that teacher leadership existed in the case study school where it appeared in four different areas of leadership practice. These areas of leadership practices (Grant, 2008, p. 93) were, for example, in the classroom, outside the classroom in curricular and extra‐curricular activities, in school‐wide leadership development and between other neighbouring schools in the community. The school had a view of teacher leadership which was strongly located within the classroom and outside the classroom in curricular and extra‐curricular activities where teachers worked and interacted with their colleagues and learners. Teacher leadership was severely limited in the area of whole school development and almost non‐existent in the area outside the school between teachers across neighbouring schools, at circuit or district level and in the community. The study suggested that the nature of teacher leadership in the case study school was a restricted form of teacher leadership (Harris and Muijs, 2005) due to a range of factors which impeded its practice. The factors were, for example, a lack of involvement of all teachers in whole school leadership and school‐wide decision‐making. Other factors were limited time for teachers in the school, a lack of leadership development amongst the principal and teachers as well as resistance for teachers to leadership in the case study school.

- Description: Solar transient eruptions are the main cause of interplanetary-magnetospheric disturbances leading to the phenomena known as geomagnetic storms. Eruptive solar events such as coronal mass ejections (CMEs) are currently considered the main cause of geomagnetic storms (GMS). GMS are strong perturbations of the Earth’s magnetic field that can affect space-borne and ground-based technological systems. The solar-terrestrial impact on modern technological systems is commonly known as Space Weather. Part of the research study described in this thesis was to investigate and establish a relationship between GMS (periods with Dst ≤ −50 nT) and their associated solar and interplanetary (IP) properties during solar cycle (SC) 23. Solar and IP geoeffective properties associated with or without CMEs were investigated and used to qualitatively characterise both intense and moderate storms. The results of this analysis specifically provide an estimate of the main sources of GMS during an average 11-year solar activity period. This study indicates that during SC 23, the majority of intense GMS (83%) were associated with CMEs, while the non-associated CME storms were dominant among moderate storms. GMS phenomena are the result of a complex and non-linear chaotic system involving the Sun, the IP medium, the magnetosphere and ionosphere, which make the prediction of these phenomena challenging. This thesis also explored the predictability of both the occurrence and strength of GMS. Due to their nonlinear driving mechanisms, the prediction of GMS was attempted by the use of neural network (NN) techniques, known for their non-linear modelling capabilities. To predict the occurrence of storms, a combination of solar and IP parameters were used as inputs in the NN model that proved to predict the occurrence of GMS with a probability of 87%. Using the solar wind (SW) and IP magnetic field (IMF) parameters, a separate NN-based model was developed to predict the storm-time strength as measured by the global Dst and ap geomagnetic indices, as well as by the locally measured K-index. The performance of the models was tested on data sets which were not part of the NN training process. The results obtained indicate that NN models provide a reliable alternative method for empirically predicting the occurrence and strength of GMS on the basis of solar and IP parameters. The demonstrated ability to predict the geoeffectiveness of solar and IP transient events is a key step in the goal towards improving space weather modelling and prediction.

- Description: The objective of this thesis is to highlight the colossal contributions made by the late Justice Watermeyer to South African tax jurisprudence. His contributions are viewed from a practical application point of view as well as from a statutory interpretative perspective. The style and technique with which he delivered his judgments are also considered to be a contribution in their own right. The core of this thesis is the analysis of seven of Justice Watermeyer‟s most influential judgments. The development and application of the principle or principles developed in each of these seven judgments is then traced chronologically through case law up until recent judgments. It is most notable that each and every phrase contained in section 11(a) of the Income Tax Act has been interpreted by Justice Watermeyer. These interpretations are still viewed as correct statements of the applicable law and will continue to be referred to on a regular basis given the fact that section 11(a) is one of the most widely contested provisions in the Income Tax Act. Several references to his approach to statutory interpretation are made through the course of the case analyses. Whilst significant evidence of a purposive oriented approach to interpretation appears in some judgments, such evidence is lacking in others. An absolute or conclusive submission in terms of his approach to statutory interpretation is not sufficiently supported. His style of judgment is also referred to and commented on, with particular focus placed on his use of illustrative examples. The contribution to South African tax law by Justice Watermeyer is found to be nothing short of enormous. He was and continues to be influential with respect to section 11(a),the definition of gross income in section 1, common law principles of tax avoidance as well as the interpretation of statutory laws of tax avoidance. It is anticipated that some of his interpretations with respect to statutory rules of tax avoidance will be referred to when the relatively new anti-avoidance provisions become the subject of litigation.

- Description: This qualitative study aims to explore attitude formation within a small sample of Tertiary level student-athletes in relation to their antecedent experiences, individual knowledge about psychology and the social factors impacting on their attitude formation. The study is intended to allow for the development of themes related to the participants’ personal responses to the questions posed to them. The participants’ answers from the interviews will allow for an in-depth analysis and interpretation of the constituents influencing attitude formation towards sport psychology consultation. Primarily, the study aims to explore how attitudes towards clinical and sport psychology practitioners are constructed in this sample. Clinical psychology is used as a contrasting reference point to explore attitude formation in sport psychology. The participants’ beliefs, knowledge sources and attitude toward clinical psychology are examined to understand the fundamental constituents of their attitudes and to understand how this might be related to attitude formation towards sport psychology. It is intended that exploration of the participants’ knowledge sources (e.g. parents, peers, media and coaches) and additional influences on attitudes towards clinical psychology are used to provide insight into how they might shape attitude formation toward sport psychology. This is viewed as particularly important as sport psychology is an increasingly important tool in assisting the enhancement of sporting performance output. This qualitative study uses four elite student-athletes from the same sporting discipline and contextual background to allow for close linkages between the participants’ responses about attitude formation to be made. The study further aims to explore and understand how similarities and differences occur between the participants’ responses which will be completed through analysing and drawing parallels within themes relating to the literature or emerging separately. The Literature Review is intended to help guide the research through providing a reference source for contextualizing individual, public and socially generated beliefs and knowledge (literacy) about mental health / psychology, the constituents of attitude formation and the student-athlete’s context. These factors were identified in the literature as crucial components in attitude formation and also assisted in the development of initial themes, thus guiding the research. Unfortunately, there was limited literature pertaining to attitude formation in relation to sport psychology services and thus provide justification for using clinical psychology to explore attitude formation in sport psychology. This initial exploration of attitude formation in clinical psychology was used as a ‘template’ for contrasting attitude formation in the sample student-athletes as an indication of attitude formation in sport psychology. The Literature Review is viewed as an integral and active component of the study that is used as a body of reference guiding the exploration and interpretation of the emergent themes. This is done through the iterative reference to past research relating to attitude formation, health beliefs, and the numerous sources of information influencing attitude formation within clinical psychology and the student-athlete context. Most importantly, the Literature Review provides a significant base of information that guides the Research Question and the particular factors that have been noted as the most significant to the research. The Literature Review is intended to guide the Research Question and highlight the significant components that need to be taken into consideration in exploring attitude formation. This study, having taken the numerous individual, social, contextual and other factors into consideration, seeks to understand how such factors combine to shape attitudes and influence attitude formation. The collection of literature on social, knowledge and antecedent factors are significant in their role of shaping attitude formation and thus have been included within the Research Question. Furthermore, the Research Question and Literature Review had an impact on the Methodology and why Thematic Analysis was selected. Given the similarities in the participants’ sporting and contextual backgrounds (e.g., being in the same crew, university and social context), it was felt that the primary determinants of attitude formation, within antecedent experiences, knowledge and social influences, would emerge in related themes and thus provide greater insight into attitude formation within the student-athlete context. A limiting factor however, does lie in the small number of participants from a limited diversity of backgrounds, experiences or factors that could assist in allowing broader generalisations of the findings. However, this study aims to understand how the particular factors influence or shape attitudes towards sport and other psychology services and aims to understand the more specific or ‘fundamental’ components of attitude formation that are experienced within the student-athlete’s context and environment.

- Description: This thesis reports on a collaborative action research case study into the teaching of visual literacy to Grade 10 learners in a rural high school in the Eastern Cape, South Africa. Visual literacy is one of the critical aspects that have been incorporated in the teaching of English First Additional Language as required by the National Curriculum Statement (Grade 10-12), which has been implemented in Grade 10 as from 2006. With the aim of improving learners’ performance in visual literacy I designed a visual literacy unit that consisted of lesson plans running over 7 periods in 10 school days. In implementing the unit the learners were first grouped and then exposed to visual grammar and visual texts and then they critically viewed such texts and designed their own. Data was collected daily in the form of individual learner journals, researcher’s journal/diary, and copies were kept of activities done by learners (individually or in groups). Also, two teachers were invited as non-participant observers to each visit a lesson. Learner focus groups were conducted and critical friends were interviewed, tape recorded and transcribed. A camera was used to take still photographs to show learner activities in groups and during group presentations. The data revealed that visual literacy could be taught meaningfully in a rural high school as the learners could identify, cut, paste and discuss elements of visual language and they finally designed their own advertisements in groups. In the analysis of data the following factors emerged as hindrances for successful teaching of visual literacy in a rural high school: lack of resources; learners’ lack of a foundation in visual literacy from Grades 7-9; and problems revolving around time management and pacing. As action research comes in spirals, this research represented the first one and the researcher found the study an eye opener and a foundation to build on in the second spiral (that is not part of this research).
