- Description: One-dimensional (1-D) titanium dioxide nanotubes (TNTs) have attracted much attention as a promising alternative electrode material for dye sensitized solar cell (DSSC). As compared to the randomly packed and disordered TiO2 nanoparticles (TNPs) network with numerous particle-particle interfaces, TNTs prove to have fascinating features than make them suitable candidates in DSSCs. Well-structured TNTs arrays are of great potential among the various types of 1D TiO2 nano-materials owing to their superior electron transport properties with limited grain boundaries. Vectorial transport of photon generated electrons along the TNTs has been reported to lead to higher charge mobility which is crucial for improvement of DSSC performances. In this work, highly adhesive titanium films were deposited on functional substrates (FS) using radio frequency (RF) sputtering technique at a sputtering output power of 1kW, operating pressure of 1.5 Pa and at a deposition temperature of 200 °C to obtain a thickness of 10 μm under an inert argon atmosphere. The duration period for sputter coating 10 μm thickness of titanium film layer was 122 minutes with sputter rate for titanium target of about 82 nm per minutes. Subsequently, the RF sputtered titanium films were anodized with 0.5 wt. percent ammonium fluoride + 0.35 wt. percent deionised water and 96 wt. percent glycerol electrolyte solution at room temperature at 60 V for 72 hours. The resulting TNTs on functional substrates (TNTs-FS) were subjected to thermal treatment at 350 °C, 450 °C, 550 °C and 650 °C for 3 hours under oxygen atmosphere. The effect of annealing temperature on the morphological, and structural properties have been scrutinized. The as prepared and thermally treated TNTs-FS were characterized using scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) and Confocal Raman Spectroscopy (CRS). SEM and HRTEM techniques were employed to confirm the presence of the TNTs-FS and also to study the structural-morphology of the TNTs as the annealing temperature increases. SEM revealed improvement in morphology with increase in sample annealing temperature, even at high temperatures such as 650 °C with no collapsing and sintering of the TNTs-FS occurring. SEM images revealed TNTs-FS with pore diameter sizes in the range between 85-170 nm. This is in compliance with HRTEM analysis, which revealed smooth and straight tube walls and improved surface morphology with increase in annealing temperature. In addition HRTEM images revealed pore diameter of TNTs-FS in the range between 85-165 nm. Furthermore, HRTEM revealed lattice fringes of 0.351, 0.352 and 0.353 nm between the neighbouring lattice fringes. All corresponding to (101) planes of anatase phase TNTs at different annealing temperatures (350-650 °C). The crystallographic structure of TNTs-FS was characterized by XRD measurements after thermal treatment at 350 °C, 450 °C, 550 °C and 650 °C. The XRD pattern revealed peaks in the wide angle range of 2θ (20° < 2θ > 80°) discovered at 29.43°, 45.10°, 56.52°, 63.5°, 64.92° and 74.81° corresponding to the planes (101), (112), (200), (105), (211) and (204) crystalline structures of the anatase TNTs. The intensity of the peaks increased with increasing annealing temperature. The strong sharp peaks indicate the large quantities and higher degrees of crystallinity of anatase phase of the TNTs. CRS Large Area Scan (LAS) and Depth profiling (DP) were employed to evaluate the crystallinity and phase distribution of TNTs-FS thermally treated at different temperatures. CRS LAS in the XY direction of TNTs-FS revealed the presence of differently crystallized anatase phases of TiO2 with Raman vibrational modes of 159.38 cm-1 (Eg), 208.37 cm-1 (Eg), 399.67 cm-1 (B1g), 514.25 cm-1 (A1g) and 641.58 cm-1 (Eg) for the samples annealed at 350 °C. The effect of annealing temperature on TiO2 phase evolution was meticulously evaluated using CRS for TNTs-FS for the samples annealed at 350 °C, 450 °C, 550 °C and 650 °C. The FWHM was estimated from CRS and decreases with increasing annealing temperature resulting in increasing crystallinity. Increase in anatase FWHM and anatase peak intensity implies higher degree of crystallinity and increasing crystallite sizes were also confirmed by XRD. Growing of titanium dioxide on functional substrates one novel contribution towards the fabrication of efficient electrode materials for solar cell development. Our method of characterizing TNTs-FS from a large area scan along the surface of the samples and depth profiling along the TNTs tube walls using confocal Raman spectroscopy prove to be a pivotal step in the development of efficient photoelectrode materials of the solar devices. , Thesis (MSc) -- Faculty of Science and Agriculture, 2017

- Description: This study focused on Knowledge Sharing Practices Amongst Librarians in Selected Federal Universities in South-Western Nigerian. The southwest geopolitical zone chosen for this study is one of the largest geopolitical zones in Nigeria. The zone has six states with six Federal universities. Each of the states in south-west zone in Nigeria has one Federal University. The study was targeted at Librarians in each of the Federal Universities. These Librarians studied were from Obafemi Awolowo University (OAU) Ile Ife, Federal University of Technology (FUTA) Akure, University of Lagos (UNILAG) Akoka, Federal University of Oye Ekiti (FUOYE) Oye Ekiti, University of Ibadan (UI) Ibadan and Federal University of Agriculture Abeokuta (FUNAAB). The aforementioned universities are located in Osun State, Ondo State, Lagos State, Ekiti State, and Oyo State, respectively. Specifically, the objectives of this study were to determine the factors that affect the knowledge sharing practices amongst librarians in the south western Federal universities in Nigeria; to find out the perception of librarians on knowledge sharing in the Federal University libraries; to investigate the method of sharing knowledge and the effectiveness of such methods among academic librarians at the selected Universities in Nigeria; as well as to determine the extent to which librarians in Federal Universities encourage information exchange and the use of modern technologies. In order to achieve these, a multistage sampling technique was used. Purposive sampling technique was first used with the criteria that all the universities selected must be owned by Federal government; and only professional librarians in the respective university libraries participated. The Total enumerative technique was also used although not all professional librarians across the six federal universities were reached, owing to few limitations. However, 147 professional librarians across all six federal university libraries in south-western zone, Nigeria were randomly selected and eventually used for the purposes of this study. This study makes use of triangulation for data collection. In other words, the instruments used for all the data collected are Questionnaire, Interview and Focus Group Discussion. This was because the nature of data collected is a combination of qualitative and quantitative data. Questionnaires (147) were administered to librarians in all the federal universities with the aid of research assistants in each of the institution libraries. Descriptive and Inferential Statistics were used to analyse the data gathered with the aid of Statistical package for Social Sciences (SPSS) version 23. Subsequently, the Interview and Focus Group Discussion were organized after retrieving data gathered through questionnaires. Focus Group Discussion (FGD) was used to get some facts in line with the objectives of the study from librarians in the areas of study. This was done with the aid of a tape recorder, which was later transcribed and descriptively analyzed. Data gathered with the aid of interview and FGD were transcribed and interpreted. From all the instruments across the areas of study, it was found that the rate at which knowledge is shared through meetings and workshops is not encouraging as the findings showed that there was a very low response in this regard. The study concluded that there were several factors that affect knowledge sharing practices in the study site. Some of the key factors that influence knowledge sharing practices include: organizational structure, provision of incentives, Managerial practices, improved ICT, social relationship and training. This therefore suggests that organizational structure, provision of incentives, managerial practices, improved ICT, social relationship, training, trust, peer influence and perceived reciprocal benefit have a significant effect on knowledge sharing practices amongst librarians in South-western federal University libraries. It was found that there was a positive and significant effect of organizational structure on knowledge sharing practices amongst librarians. Results of the descriptive statistics on the perception of some librarians showed that librarians understood the concept of knowledge sharing as they agreed that knowledge possessed by an individual should be shared with another individual. In addition, on average, librarians supported the fact that knowledge sharing can bring innovation and creativity to library services. Although the findings were somehow consistent with previous studies, this study noted a number of contradictions and gaps that border on some of these factors. These are mode of sharing knowledge; particularly with respect to the availability of ICT facilities and their usage and the extent to which librarians in the study area share their knowledge which seems to be somehow not encouraging. Based on the findings, it was recommended that Organizational structures within each University library should be friendly and productive. Subsequently, No matter what, more is better than less. Librarians in all the six selected Southwestern university libraries should be motivated by giving them more incentives or rewards (both intrinsic and extrinsic rewards). In other words, there is a need for the management of the respective institutions to introduce additional incentives in order for their staff (librarians) to be fully motivated to increase their impetus to engage more in knowledge sharing practices. Despite the positive perception of librarians in the area of study, they still need to be motivated. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2017

- Description: Discrimination is a serious violation of human rights and it is strongly condemned by various legal instruments in South Africa. The South African Constitution (1996), Promotion of Administration Justice Act (2000) and Promotion of Equality and Prevention of Unfair Discrimination Act (2000) forbade discrimination and exclusion of pregnant learners from school. In spite of these legislative frameworks, School Governing Body (SGB) continues to exclude pregnant learners from school. SGB claimed that pregnant learners are harmful to other female learners and is becoming a significant barrier to girls’ education. Research shows that learners’ pregnancy is predominant in rural areas, apparently poses a threat to female education (Annual School Survey Report, 2010). The purpose of this dissertation is to establish that SGB lacks power to do so; however, their resistance to the law by excluding the pregnant learners from school is in conflict with the South African Constitution. This dissertation investigated an alternative instrument of legal remedy to reduce the problem of learners’ pregnancy rather than exclusion. The theoretical framework of this study is informed by Public Policy Theory (Ijeoma, 2010). Literatures and scholarly works on education law (Oosthuizen, 2015) and articles on Learners’ pregnancy shall be reviewed (Morell, Bhana & Shefer, 2012). The study followed qualitative research method which utilizes a transformative research paradigm that provides a collective voice for the participants. The data is collected through focused interview and open-ended questions, and subsequently analysed to establish that SGB lacks power to exclude a pregnant learner from school. Finally, the study reveals an alternative instrument of legal remedy to reduce the alarming number of pregnant learners rather than exclusion. , Thesis (MEd) -- Faculty of Education, 2017

- Description: This study offers a comprehensive examination of the Role of the Liberation Movements’ Archives in Shaping History Writing in a Post-Apartheid South Africa. It is based on the Liberation Archives housed at the National Heritage and Cultural Studies (NAHECS) at the University of Fort Hare, near the town of Alice in the Eastern Cape Province. A new narrative, grounded in the exploration and advantages of the use of these materials in their totality, given the new environment of research created under the new dispensation, has now become possible. The first chapter begins with an overview of the nature of archives in general and proceeds from there to consider the unique circumstances under which the different liberation movements of South Africa constructed their archives, and how these circumstances affected the nature of the materials preserved therein. One key point made here is that the liberation movement, as it spearheaded the struggle against apartheid, had already positioned itself as a “Government in Waiting,” convinced of the justness of its cause, and of the ultimate defeat of apartheid leading to he political seizure of power by the people. Hence, it created struggle materials seen as vehicles for the realisation and attainment of this objective. For this purpose, the appropriate housekeeping, viewing, consultation and access is absolutely relevant. The second chapter looks at the changing environment in which the repatriation of the struggle archives was implemented, and the decision to place them specifically at the University of Fort Hare and challenges. The third chapter narrates the difficulties encountered following the location of documents at Fort Hare, contestations, and contradictions between the stakeholders and the ultimate resolutions. The fourth and longest chapter goes to the heart of this thesis which dispel the myths created by the colonists and their historians intended to obscure the oppressed into embracing a historiography of South Africa that crossly flawed and distorted, silent and ignorant of reflecting early African societal developments which were evolving undisturbed at their own rate under socio-cultural and geographical conditions prior the advent of colonialism and the consequences. Therefore, based on these circumstances one can see that the installation of the new dispensation was not the end of the struggle, but the opening of a new chapter, the struggle against the conceptual legacy of apartheid and its vestiges. An evaluation of the consultation and exploitation of the archival collections comprises this subject in the last chapter of this study. Perusing them, one learns and realizes that the objective of the liberation movements was immense, to reconnect the marginalised of their once trampled and vilified history in order to inspire and empower them to reclaim their lost sense of belonging, identity, pride and to restore their humanity. This has been vindicated by the wide range of researchers and viewers from home and afar who have turned out to consult the archives in order to unpack the complexities of the South African history and that of the struggle. The information they contain serve as guides of addressing such complexities to arrest current transitional challenges, and offer solutions for some in articulating a need of building a new cohesive nation in a post-apartheid era. This is precisely what the liberation movement had in mind when it took a decision to gather together the struggle materials and have them repatriated for preservation and access purposes. It was not just generosity on its part, but also a display of the patriotic and passionate responsibility to the oppressed in particular and humanity in general to fathom and unpack the complexities of the South African historiography. , Thesis (PhD) -- Faculty of Social Science and Humanities,2021

- Description: This study sought to examine a sociological approach of the influence of regular provision of school feeding scheme on learners’ academic performance at Ngqele Primary School, Nkonkobe Municipality, Eastern Cape Province, South Africa. The study explored the views of teachers and parents pertaining to regular provision of school feeding scheme on learners’ academic performance. In addition, the study examined the impact of regular provision of school feeding scheme on school attendance and the sustainability of the regular provision of school feeding scheme. The study utilized both qualitative and quantitative research methods in the form of in-depth interviews, and a survey method. The process was made possible through the use of purposive sampling and cluster sampling to generate the targeted participants of the study. The findings of the study have shown that the school feeding scheme has got an impact on learner’s academic performance due to the fact that learners are able to listen and pay attention to the teacher if they are fed, the SFS has a positive impact on learners’ attendance and high enrolment. However, the study has also shown that, despite the positive impact of the school feeding Scheme, there were some challenges that also impacted negatively on learners, the school and the implementation of the programme. Such challenges include irregular supply of food, food shortages and poor quality of food.

- Description: The Bring Your Own Device (BYOD) phenomenon has become prevalent in the modern-day workplace, including the banking industry. Employees who own devices have become the unintended administrators of the organisation’s information as their mobile devices often carry information belonging to the organisation. The unintended administrator is not necessarily schooled or aware of the information security risks and challenges that are associated with the BYOD. This inadvertently shifts the management of organisational information security from the information technology (IT) administrator to the unintended administrator. This shift leaves the organisation at risk of information security breaches that can permeate the organisation, which result from the behaviour that the unintended administrator displays when operating the mobile device. This study introduces the BYOD Information Security Behavioural (BISB) model. The model constructs are a combination of individual and organisational traits of the unintended administrator. The purpose of this study is to mitigate the risks posed by the unintended administrator in organisations through the implementation this model. The risk that the unintended administrator poses in relation to the BYOD phenomenon results in chief information officers (CIOs) being unable to totally control these mobile devices. Traditional endpoint information security management tools and methods can no longer secure devices in the BYOD the way they can in the traditional network where they are confined to the organisation’s IT administrator. This results in the organisation’s information security becoming the responsibility of the unintended administrator. This study was conducted in the banking sector in Zimbabwe. It is noteworthy that the BYOD phenomenon has become prevalent in the banking sector among other organisational sectors like education, health or even government departments. Information security is also an important component of the banks as such and a choice was made to conduct the study in the banking industry. The design science research paradigm was followed in this study and included a survey of 270 bank employees in Zimbabwe, which received 170 complete responses. A literature review on both employee behaviour and organisational culture was conducted, followed by a case study of a commercial bank in Zimbabwe. The literature review culminated in traits that were then classified as individual traits and organisational traits. Six constructs –, knowledge, attitude, habit, environment, governance and training – were identified from the literature and combined to form the BYOD information security behavioural (BISB) model. Statistical calculations were conducted on the survey results which informed the reliability, validity and rigour of the model constructs. An expert review including industry experts was conducted to evaluate the BISB model. This study concludes by recommending that organisations in Zimbabwe should make use of the BISB model to mitigate the information security risks that are posed by the unintended administrator. While there are technical solutions for managing the information security risks that come with the BYOD, this study points out that without harnessing the individual and organisational traits that make up the BYOD information security behavioural model for the unintended administrator, technical solutions alone will not be effective.

A critical analysis of the dynamics of intergovernmental relations in Zimbabwe

- Description: The field of intergovernmental relations (IGR), both from a conceptual and practical perspective presents a contested order in Zimbabwe’s political and public administration discourse, with a fairly long and complex historical and institutional context. The advent of colonialism in Zimbabwe (then Rhodesia) gave birth to a dualised form of government with a separatist development agenda. The dualistic model of government was anchored on a segregationist centralist ideology that advanced a white supremacist agenda while entrenching underdevelopment in native areas. This was attained through the use of draconic and ingrained racially discriminatory laws, ordinances and policy enactments, inter alia, the 1910 High Commissioner’s Proclamation, the Native Councils Act, the African Councils Act, and the District Councils Act which supported the overriding philosophy of colonialist hegemony. The direct rule policy was used and in practice, administrative, political, judicial and legislative powers were under the purview of the whites. Under this political dispensation, the nature of IGR was typically a master-servant relationship as African institutions had limited policy latitude under the tentacles of race-driven white control over the socio-economic and political space with an exploitative and subservient underpinning. The demise of colonialism and the birth of independent Zimbabwe in 1980 ushered a new political dispensation. The post-independence government embarked on a number of reforms aimed at dismantling the racist undertones of government. These reforms include the expanded decentralization frameworks supported by legislative instruments and policies such as the 1984 Prime Minister’s Directive and the 1996 thirteen principles of decentralization. Other key reforms are the 1996 Urban Councils Act, Chapter 29:15 and the 1988 Rural District Councils Act, Chapter 29:13. However, it is important to note that despite this plethora of legislation and reforms purportedly meant to dismantle racist backed institutional differentiation, the new national government did not depose its excessive control on sub-national governments. It is therefore an insoluble contradiction that the legislation and institutions created in post-independence Zimbabwe promoted the autonomy of sub-national governments while broadening democracy and citizen participation. This era rather presents an aporetic discourse epitomized by the national government’s perfection of colonial dominance approaches through creating legislation and institutions to retain wide and extensive control of sub-national governments. The Global Political Agreement of 2009 culminated into the promulgation of the Constitution of Zimbabwe Amendment Number 20 of 2013 with provisions for devolution of power, Provincial and Metropolitan Councils and the enshrinement of Local Government as a tier of government with constitutionally guaranteed autonomy. However, despite these reforms with far reaching implications on the configuration of IGR, the ZANUPF led national government is lethargic in implementing them. This has sparked controversy as these constitutional reforms and their potential to promote an integrated and efficient system of governance may turn out to be a pyrrhic victory. This is so because the necessary legislation anchoring the constitutional reforms may not be created in the foreseeable future as the current national government views devolution, for instance, as tantamount to surrendering political power to sub-national institutions. The purpose of the study was to critically examine the dynamics of intergovernmental relations in Zimbabwe. The overlapping authority model of IGR and the theory of networked governance underpinned the study. A comparative study of IGR was conducted focusing on two federal nations (United States of America) and Nigeria) and two unitary nations (United Kingdom and South Africa). A qualitative phenomenological methodology was used and the sample size was 20 respondents selected using the purposive sampling technique. Data was collected using in-depth interviews and analyzed using thematic analysis and critical discourse analysis. Key findings of the study reflected on the conception and relevance of IGR in unitary nations in contrast to classical perspectives that restricted the field as a discourse of federalism. The study established that the unitary system of Zimbabwe is anchored on a strong centralist ideology that suffocates the autonomy of sub-national institutions. In the same context, there is absence of political will on the part of the ZANUPF led government to implement crucial constitutional reforms that have a bearing on the configuration of IGR. The study also revealed that political party incongruence is a threat to intergovernmental coordination, integrated planning and collaborative development. Various recommendations were made from the study and these include that national government should expedite the implementation of the Constitution, codification of IGR by way of legislation and rationalization of fiscal transfers and intergovernmental fiscal equalization.

- Description: Trade facilitation practices are an attempt to eradicate non-tariff barriers. Barriers to trade may be encountered before goods reach the border, at the border or after goods reach the border. This study is concerned with processes that occur at the border. This suggests that trade facilitation is viewed within the context of customs procedures and operations at the border posts that have been identified. This study undertakes an analysis of trade facilitation practices in the Zimbabwe customs administration. The study endeavours to identify bottlenecks in the movement of goods across borders. The study tries to establish the extent to which trade facilitation practices in Zimbabwe conform to international best practice. The study also attempts to establish opportunities and threats for trade facilitation in the current arrangements. The researcher establishes that the following areas require improvement through further study; simplicity of procedures, transparency of processes, cooperation of stakeholders, standardisation of processes harmonisation of processes and predictability of processes .The research problem lies in the delays and increased trade transaction costs that have been reported by traders. This ultimately leads to traders who are not competitive on the international scene. It also makes it difficult for small to medium enterprises since they are affected more by high trade transaction costs due to lower profits and turnover. The Zimbabwean economy is dominated by small to medium enterprises which contribute significantly to the economy. The assumption of the study is that if trade facilitation practices are implemented trade volumes will increase leading to a vibrant national economy. The research problem is examined through an assessment of the perception of traders, clearing agents and customs officials on the effectiveness of trade facilitation practices that are currently in place. A mixture of qualitative and quantitative methodologies was used. The major tool used was a self-administered questionnaire issued to traders. Focus group discussions and secondary data from documents were important, especially for qualitative data. The conclusions of the research are premised on the responses by the respondents. The study takes a particular interest in trade facilitation measures prescribed by regional, multilateral and plurilateral organisations. The study examines the extent of conformity to trade facilitation measures prescribed by international organisations. The recommendations presented in the study are derived from the input and responses provided by the participants. Recommendations presented are aimed at bringing about solutions to the shortcomings in trade facilitation practices. The study has identified areas that need to be addressed so as to ensure facilitation of trade. However there are still some areas that require further studies.

- Description: African countries have become synonymous with policy drafters and abortive policy implementers. After independence from long period colonialism, slavery and apartheid, African states policy administrators began putting in place policies to improve either the living conditions of citizens or the inequities emanating from the administration of colonial governments. However, these policies do little to naught to meet the aforementioned goals. The Free Education Systems in Nigeria and Ghana, and the Indigenization Policy in Zimbabwe are examples of policies that experienced miscarriage of policy implementation in the past. This study therefore, aspires to explore the Broad Based Black Economic Empowerment policy implementation in the forest sector and specifically identify bottlenecks in the implementation processes in South Africa. Qualitative approach was used in order to meet the primary and secondary objectives of the study. Semi structured interview questions were administered to relevant companies, institutions and the municipality which were purposely sampled to capture the processes of the BBBEE implementation. The study revealed that measured entities are complying with the prescript of the policy but that finance and a continuous policy amendment presents a bottleneck in the implementation dynamics. Lastly, labour intensive measured entities find it impossible to meet the skills development element due to high cost of training. These results suggest that the value envisaged is not being met. The study also found that verification agencies are effectively providing their watchdog function in the implementation of the policy however the use of technology is non-existent in monitoring the process. Finally the study found that agencies are hired by measured entities to verify their BBBEE status which presents a huge inducement for both parties to collude. It also found that the policy is implemented in a top-down approach hence municipalities have been relegated from the implementation process. The study recommends decentralization of the policy in a strategy called Local Economic Equity for the Disadvantaged (LEED) which involves the expertise of white South Africans and permanent resident people in order to build truly inclusive society envisaged by the Constitution of South Africa. Additionally, it recommends the use of technology dubbed e-BBBEE to implement the policy.

- Description: Mental illness rates are climbing, locally and globally. The World Health Organization (2001) has claimed that one in four people will be affected by a psychiatric disorder during their lifetime. With this in mind, there is an array of psychometric assessment measures that are used as tools to assist in the mental health care field. Two such measures are the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory-II (BDI-II). These measures are used globally to assist with the diagnosis and treatment of depression and anxiety. However, in South Africa, a paucity of normative indicators exists. This research set out to determine if there are significant differences in performance on the BAI and BDI-II when comparing a sample from the Eastern Cape, South Africa, to the international norms. It was found that performances on the BAI between the local sample and the international sample did not differ significantly. The local sample, on average, performed 4.76 points lower on the BDI-II than those assessed in the international norms. A series of theoretical models are explored in elucidating the findings in this study.

- Description: The governance of data assets has become a topical issue in the public sector. Government departments are faced with increasingly complex data and information arising from multiple projects, different departments, divisions and several stakeholders seeking data for divergent end uses. However, an exploratory study of the literature regarding data governance in government departments of the Eastern Cape province of South Africa suggest that there are no clear data governance processes in place within the departments. The research question “How can a data governance maturity evaluation model enhance data governance processes in the Eastern Cape government departments” was derived as a result of a perceived need for government departments of the province to manage their critical data assets in a manner which promotes accurate, verifiable and relevant fiscal and strategic planning. Following the review of current literature in the data governance domain, a conceptual data governance evaluation maturity model was developed and produced. The conceptual model was influenced by the IBM data governance maturity model (2007) and it was aimed at addressing the gaps in the reference model to suit the context of the Eastern Cape government departments and the governance of their data assets. A qualitative phase of empirical data collection was conducted to test the components of the conceptual model. A quantitative instrument, derived from the findings of the qualitative study, as well as the components of the refined model was administered to 50 participants in the same departments where qualitative data was collected, with additional participants being drawn from three other departments. Pragmatism was the guiding philosophy for the research. The Contingency and Institutional theories form the theoretical grounding for the study. Design Science guidelines by Hevner et al (2004), Peffers et al’s (2008) Six Steps in Design Science and Drechsler & Hevner’s (2016) Fourth Cycle of Design Science were employed to construct, improve, validate and evaluate the final artefact. Findings confirmed the literature that data governance is lacking in government departments. It is asserted that the implementation of this model will improve the way data assets are recorded, used, archived and disposed in government departments of the Eastern Cape. The outcome of this research was the development and production of a data governance maturity evaluation model as well as a process document which gives a roadmap of how to move from one maturity level to another.

A quantitative instrument, derived from the findings of the qualitative study, as well as the components of the refined model was administered to 50 participants in the same departments where qualitative data was collected, with additional participants being drawn from three other departments. Pragmatism was the guiding philosophy for the research. The Contingency and Institutional theories form the theoretical grounding for the study. Design Science guidelines by Hevner et al (2004), Peffers et al’s (2008) Six Steps in Design Science and Drechsler & Hevner’s (2016) Fourth Cycle of Design Science were employed to construct, improve, validate and evaluate the final artefact. Findings confirmed the literature that data governance is lacking in government departments. It is asserted that the implementation of this model will improve the way data assets are recorded, used, archived and disposed in government departments of the Eastern Cape. The outcome of this research was the development and production of a data governance maturity evaluation model as well as a process document which gives a roadmap of how to move from one maturity level to another.

- Description: School-based sexuality education has been the subject of research in the social sciences and pedagogical spheres globally. In South Africa, growing interest among social scientists in the topic, were ignited by the introduction of sexuality education as a compulsory part of Life Orientation (LO) by the late 1990s. However, the implementation of LO has been problematic. Reviewed literature in the current study, reveals how the dominance of the heterosex discourse is foregrounded in LO content on gender and sexuality. The current study was aimed at examining the construction of gendered relationships in LO textbooks. The study sampled LO textbooks for Grades 10-12, learners in these grades are between the mean ages 16-18 years. This group is the target group, because they are legally afforded the right to consent to sexual activity with peers, within the same age bracket. Conducted from a social constructionist perspective, the current study employed qualitative methods of inquiry (textual analysis). Against the backdrop of heterosexuality as norm, it was the aim of the current study to understand the subject positions made available for female learners to construct themselves, within the discursive spaces in LO content. Findings suggest that two discourses namely: the heterosex discourse and the discourse of danger and disease, dominate in LO content on gender and sexuality. This leads to the construction of gendered relationships a s inherently heterosexual, leading to the marginalisation of relationships that fall outside of the norm. The female learner is positioned as a passive-victim, incapable of exercising sexual agency, while young men are positioned as inherently more powerful members of the intimate relationships or dangerous sexual predators. In the discourse of danger and disease, she is also positioned as a potential victim but the focus is on equipping her with skills, in a way which positioned her as an active-resistor in refusing sexual activity; and being in control of decision-making on issues of safety in relationships. The implications of these contradictions, is that they focus on the individual and disallow her taking up of sexual agency, and disregard the context in which she has to do so.

- Description: In this study the analysis of the organisational practices in the South African public sector revealed that there is a practical limitation, anchored on the absence of a suitable framework for enhancing the effectiveness of strategic leadership. The research engaged with studies and theories that confirmed that the application of effective strategic leadership enhances the performance of public sector organisations. However, such an analysis revealed no well-defined strategic leadership framework that may be used for improving the successful implementation of programmes in the public sector as a whole and more especially, the Eastern Cape Department of Education (ECDoE). The study therefore interpreted that a significant improvement in the performance of the ECDoE may be effected through the prioritisation of strategic leadership and thereby enhancing its effectiveness. Hence, the primary research objective for this study was to examine strategic leadership and to consider the variables impacting the application of strategic leadership in the ECDoE, so that a framework may be formulated to enhance the effectiveness of strategic leadership in the ECDoE. The data analysis, research observations, findings and interpretations as well as the literature review enabled the researcher to determine the strategic leadership framework that may be postulated for application in the ECDoE. The research data in essence supports the indications in the literature that strategic leadership has a positive effect on enhancing organisational performance and success. The key findings and significant conclusions drawn from the study indicated a definite need to enhance the effectiveness of strategic leadership in the ECDoE and that the associated leadership challenges in the sector have to be addressed to enable more efficient and effective service delivery, increase learner performance and improve organisational success. The researcher has therefore postulated the framework in figure 10 to enhance the effectiveness of strategic leadership in ECDoE and presents it for consideration by the political and administrative leadership for adoption in the ECDoE. The development of this strategic leadership framework by the researcher was informed by the various leadership models, leadership theories, leadership styles and change management strategies examined in the literature review of this study and further directed by the research findings and conclusions that illuminated the challenges that confront ECDoE in the application of strategic leadership in the sector. The framework postulated has three distinct but inter-related steps and this study theorises that the effectiveness of strategic leadership is influenced by the extent to which the managers or leaders determine the specific context and apply the appropriate leadership style (Step 1), implement the selected leadership style in conjunction with the application of appropriate accompanying management strategies (Step 2), and monitor the resulting effects on enhancing the performance of the public sector organisations (Step 3). The researcher also adopted a systems-thinking approach and identified four pillars that transcend organisational service delivery and integrated them to constitute a proposed model for enhancing service delivery, improving implementation of plans and promoting organisational success in ECDoE. The model postulated by the researcher is based on “policies, procedures, systems and structures”, as illustrated in figure 11. The pillars of this proposed model for service delivery are inter-related, inter-locking and at times overlapping. Arising from the literature review and the case study of ECDoE, areas for further research have been identified such as: a more in-depth probing of the significance, role and impact of strategic leadership in all public sector institutions in South Africa; an examination of the Senior Management Services (SMS) mandates given by the Department of Public Service and Administration (DPSA) with regard to strategic leadership; an exploration of the implementation constraints of the National Development Plan (NDP) linked to the positioning of strategic leadership; and, an examination of the role and impact of the training and development programmes in strategic leadership, co-ordinated by the National School of Government (NSG) in South Africa.

- Description: Traditional healers have a different understanding of psychological illnesses to the western paradigm as well as a different way of diagnosing and treating psychological illnesses. Aims and Objectives. This study’s aim is to examine how traditional healers understand the causes of mental illness mainly focusing on amafufunyana and how this understanding informs treatments methods. Method. This has been done based on hermeneutic phenomenology by drawing from the lived experience of traditional healers through a focus group interview. Results. Upon analysis of the data it becomes clear that traditional healers understand the aetiology of amafufunyana to be supernatural forces. Amafufunyana present in overt and covert symptoms and the diagnostic process entails connecting with the ancestors for their guidance and confirmation of diagnosis, as well as guidance on which imithi to use. The treatment process is congruent with the diagnostic process as it also entails guidance from the ancestors on which imithi to use. Other valuable aspects of traditional healing were brought forward while conducting this study. The aspect of protection from the ancestors was emphasised. It became evident in the analysis of this study that the rituals that are performed in order to appease the ancestors facilitate the connection to the ancestors and through maintaining this connect one can be protected from an array of illnesses and misfortunes. Recommendations. It is recommended that recommended that more studies are conducted with traditional healers in order to give them an opportunity to elaborate on their lived experience of healing, as it was observed that a majority of literature speak on behalf of traditional healers.

- Description: There is a gap in healthcare service delivery within low resource settings of South Africa. These areas are under-serviced because of poor health infrastructure and few available medical experts. This contributes immensely to poor health care delivery especially to chronically ill diabetic patients and increases mortality rates. However, innovative remote patient monitoring (RPM) systems have been developed to curb the above challenge in recent years. Unfortunately, most of these systems are standalone and are incompatible with one another. Most of them relay on Internet for connectivity which is imminent in low resource settings. This makes continuity of care of chronic ill patients a great challenge. Additional, the efficacy and feasibility of RPM using mobile phones in low resource settings of South Africa are still unknown. It was also noted that none of these systems have been developed for a clinical trial. The goal of this study was to provide a standard framework that allows optimal design of mobile RPM systems which are interoperable. The objectives were to investigate the RPM system efficacy and reliability in low resource settings and determine its effects on clinical management, self-care and health outcomes. The framework was validated with a clinical trial to remotely monitor diabetic adults in Limpopo province of South Africa. A prototype system was developed based on sound user centric design process and enterprise architectural principles to remotely monitor diabetic elderly patients using cellular technologies and existing hospital infrastructure. It was evaluated using a controlled, randomized clinical trial for 6 months. There were 120 patients who took part in the study and were categorized into two groups, the intervention Group X and the control Group Y. Each group comprised of 60 participants. Evidence from this study justified the feasibility and possibility of long term implementation of RPM system to cater for chronic ill patients in low resource settings worldwide. Results showed that the self-care and normal blood glucose levels improved for both groups whereas quality of life improved only for Group X. It was shown that extensive self-care knowledge with the help of RPM system improved self-care and helped normalize their glucose levels. The hospital admissions and mortality between the two groups did not differ much. However, the intervention group had more hospital visits than the control group because the participants were requested to visit the hospitals in case of emergency. The users perceived the RPM system as feasible and effective way of clinical management and self-care. Due to wide acceptance, some patients were even willing to continue using the system after the trial. Home measurements proved to be reliable and helped improve self-care. In future, a standardized and unified framework based on rule set would provide comprehensive remote healthcare allowing continuous patient monitoring at a reduced overall cost thereby decreasing mortality rates.

- Description: South Africa’s health status is in constant dismay, especially while under the strain of the quadruple burden of disease. The adoption of personal electronic health records (PEHRs) can be seen as a means to improve this status by empowering patients to manage their health and lifestyle better. While from the healthcare provider’s perspective, PEHRs has the ability to reduce medical errors; provide better communication channels and enhance the monitoring of patients. Despite these benefits for both healthcare providers and patients, there are three distinct information security threats relating to PEHRs. These threats refer to the individual, data in transit, and at rest. South Africa is still considered to be inexperienced with PEHRs, and consider it a relatively new concept to the healthcare system. The National e-Health Strategy and Protection of Personal Information Bill were discussed and compared to international standards in order to ascertain South Africa’s current standing on mobile healthcare privacy. However, there are no specific privacy and security controls in place to protect patients that access personal electronic health records through mobile devices. Therefore, the aim of this study is the development of a privacy management framework (PMF) to mitigate these privacy concerns. Following an interpretivistic approach to research, qualitative data was analysed from literature, and the privacy framework evaluated through expert reviews. The proposed PMF consists of 3 tiers, beginning with the top tier. The first tier relates to an organisations interpretation and understanding of data privacy laws and regulations, and in ensuring compliance with these laws. The second tier refers to two support pillars to maintain the first tier. These pillars are based on elements of operational privacy, as well as auditing and reviewing. The third tier serves as the basic foundation upon which the PMF was developed. It is mainly focused with creating privacy awareness amongst healthcare providers and patients by creating: training regimes on security and privacy threats, efficient communication standards, and constant ongoing support from top level management.

- Description: It is of paramount importance to highlight that the South African government is established in terms of the Constitution of the Republic of South Africa of 1996. Whilst the government of South Africa is one, it consists of three spheres namely; national, provincial and local. These spheres of government are naturally distinctive, interdependent and interrelated. This is expressed in terms of section 41(1) of the Constitution, which requires that there should be co-operation, mutual trust and good faith amongst these three spheres of government. This form of a relationship compels different spheres to inform and consult one another on matters of common interest, co-ordinate their legislation, and adhere to agreed procedures in accordance with the provisions of the constitution which is the supreme law of the Republic. The study sort to find a strategic framework for managing and implementation of the Intergovernmental Relations Policy in Selected Eastern Cape Municipalities. A purposive sampling technique was used to identify the sample elements. The sample was composed of 160 participants and a semi-structured questionnaire was administered to the participants to gather information pertaining the research problem. A mixed research method was used to analyse the data gathered. The sampled respondents were municipal and government employees from various departments who have knowledge of the IGR policy. The study findings pointed out that the current framework on intergovernmental relations was ineffective in the Eastern Cape municipalities that were surveyed. Respondents pointed to a number of shortfalls in the implementation of the intergovernmental relations, which made it ineffective in improving how these municipalities operated and rendered service delivery. A number of factors inhibiting the effectiveness of the intergovernmental relations included lack of communication, poor coordination, lack of clear strategy, poor budgets amongst other factors. Based on the findings of the study, the researcher developed a strategic framework that could be adopted by municipalities in the Eastern Cape. The functionality of this framework would be influenced by the corrective measures taken by the municipalities in addressing the underlying problems of the current intergovernmental relations, as identified by the respondents.

- Description: The early efforts of Booth, Johnson, Rubidge, Catuneanu, de Wit, Chevallier, Stankiewicz, Weckmann and many other scientists in studying the Karoo Supergroup has led to comprehensive documentation of the geology on the main Karoo Basin with regards to understanding the age, sedimentology, sedimentary facies and depositional environments. In spite of these studies, the subsurface structure, variations in thickness of various formations in large parts of the basin, the location and orientation of subsurface dolerite intrusions, and the depth to magnetic and gravity sources remains poorly documented. A geological study with the aid of geophysical techniques, magnetic and gravity, was conducted in the southwestern part of the main Karoo Basin. The objectives of the study were to construct numerous models of the main basin that image the crust to a depth of 45 km, to determine thicknesses of various formations, to relate observed geophysical anomalies with geological bodies and lineaments, to estimate the depth of existing anomalous bodies, to determine densities and porosity of various formations, as well as to determine the mineralogy of various rocks in the Karoo Basin. In total, seventy one rock samples were collected in the main Karoo Basin for density and mineralogical studies. The density results showed that the Beaufort and Ecca Group rocks have the low mean density of 2.490 g/cm3 amongst the rocks while the dolerite intrusions have the highest mean density of 2.697 g/cm3. The porosities of various rocks determined from the measured rock densities revealed that the Ecca Group shales, particularly the Whitehill Formation has the highest porosity of 4.5percent, while the Collingham Formation has the least porosity of 1.4 percent amongst the Ecca Group shales. Mineralogical analysis of seventeen XRD samples and 26 thin sections indicate that quartz, kaolinite, and plagioclase occur as the major mineral in most sandstones and shales in the Karoo Basin, while the pyrophyllite, smectite, and talc occur as minor minerals. Other mineral constituents include, calcite, mica, and amphibole. The 2½ dimensional (2½ D) gravity modelling along seven selected profiles, across the Beattie Magnetic Anomaly (BMA), revealed that the Ecca Group sediments, a target for shale gas exploration in the Karoo, occurs within a depth range of 0 - 4000 m from the surface. The basin deepens to a depth of 4600 m in the southwestern region, near the front of the Cape Fold Belt. It was observed as well that the Karoo dolerite sills are connected at depths and are mostly concentrated at the centre, the deepest part of the basin with some having saucer shape - like structure. These observations correspond well with the borehole data from AB 1/65 and QU 1/65 presented in Linol and de Wit (2016). Thickness isochore maps that were extracted from the gravity models indicate that the Ecca Group, which is the main target for hydrocarbon exploration, thickens to the south away from the centre of the basin and reaches thicknesses of greater than 3680 m. The Beaufort Group proves to be the thickest succession in the Karoo Basin with an estimated thickness of up to 6046 m. Constructed geophysical maps with the geology overlain reveal that most magnetic anomalies are due to dolerite intrusions, while gravity lows are due to less dense shales of the Ecca Group. The depth slices of magnetic data indicate that near surface magnetic bodies occur within the depth of 42 m from the surface whereas deep seated ones occur as deep as 9488 m and possibly deeper. Gravity depth slices reveal signatures that are predominant at depth of 2403 m are of short wavelength and are mainly lineaments and circular structures. They ultimately disappear at depth of 7120 m. The depth slices further indicate that the intensity of both magnetic and gravity long wavelength signatures become stronger with increasing depths.

- Description: The early efforts of Booth, Johnson, Rubidge, Catuneanu, de Wit, Chevallier, Stankiewicz, Weckmann and many other scientists in studying the Karoo Supergroup has led to comprehensive documentation of the geology on the main Karoo Basin with regards to understanding the age, sedimentology, sedimentary facies and depositional environments. In spite of these studies, the subsurface structure, variations in thickness of various formations in large parts of the basin, the location and orientation of subsurface dolerite intrusions, and the depth to magnetic and gravity sources remains poorly documented. A geological study with the aid of geophysical techniques, magnetic and gravity, was conducted in the southwestern part of the main Karoo Basin. The objectives of the study were to construct numerous models of the main basin that image the crust to a depth of 45 km, to determine thicknesses of various formations, to relate observed geophysical anomalies with geological bodies and lineaments, to estimate the depth of existing anomalous bodies, to determine densities and porosity of various formations, as well as to determine the mineralogy of various rocks in the Karoo Basin. In total, seventy one rock samples were collected in the main Karoo Basin for density and mineralogical studies. The density results showed that the Beaufort and Ecca Group rocks have the low mean density of 2.490 g/cm3 amongst the rocks while the dolerite intrusions have the highest mean density of 2.697 g/cm3. The porosities of various rocks determined from the measured rock densities revealed that the Ecca Group shales, particularly the Whitehill Formation has the highest porosity of 4.5percent, while the Collingham Formation has the least porosity of 1.4 percent amongst the Ecca Group shales.

- Description: Background: The National Strategic Plan 2012-2016 is advocating for zero new infections due to vertical transmission. This goal has not yet been achieved. This study evaluated whether the prevention of mother-to-child vertical transmission (PMTCT) of Human Immuno-deficiency Virus (HIV) programmes in South Africa are based on evidence. Aim: The aim of this study was to conduct a systematic review of the available literature comparing PMTCT antiretroviral regimens published between the years 2000 to 2015 and to do a document analysis of the current implemented PMTCT programme to evaluate if it is based on best evidence. Rational: The rational of the systematic review and the document analysis were to assess whether the latest PMTCT policy was based on evidence and to critically analyse published articles that addressed aspects related to efficacy and efficiency of PMTCT programmes to reduce transmission of HIV from mothers to their infants. Methods: Overall 25 randomised controlled trials and primary studies that assessed efficacy of ARV regimens to prevent mother-to-child transmission of the HIV during pregnancy, labour and the postnatal periods were systematically reviewed. In 1997 the first trial began and the last one ended in 2012. Twelve guidelines referring to PMTCT were sampled and they were published by WHO and Department of Health South Africa from 2001 to 2015. The document analysis was only based on National consolidated guidelines for the prevention of mother-to-child transmission of HIV (PMTCT) and the management of HIV in children, adolescents and adults April, 2015. Findings: The systematic review illustrated that significantly fewer infants tested HIV-positive when exposed to a longer ARV regime although there was no significant difference once the infants reached six months of age. Different ARVs have a similar Preamble effect on maternal deaths; however, a double or triple combination of ARVs is superior to monotherapy to decrease infant deaths. Common maternal adverse reactions to ARVs include anaemia, bronchopneumonia, and maculopapular rash. Infant adverse events included septicaemia, pneumonia, gastroenteritis, fever and maculopapular rash. The document analysis has shown that the PMTCT policy is mainly based on evidence from randomised controlled trials and systematic reviews. Occasionally some statements are still based on lower categories of evidence such as non-experimental descriptive studies. Conclusion: The systematic review showed that double and triple ARV therapy is superior to monotherapy and that the longer the mother and her infant are exposed to ARV therapy the better the results are to prevent MTCT. Adverse events are always posing a challenge and as with any other medication, caregivers must be aware of potential adverse reactions. The National consolidated guidelines for the prevention of mother-to-child transmission of HIV (PMTCT) and the management of HIV in children, adolescents and adults April 2015 is based on evidence, but the policy itself does not include any reference to evidence.
