- 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: Publisher version , Given the high rate of intimate partner violence (IPV), understanding how counsellors talk about IPV and their interventions is important. The authors conducted narrative interviews with eight counsellors from non-governmental organisations (NGOs) working with IPV. Using narrative-discursive methodology, this qualitative study paid attention to the discursive resources that the participants drew upon. Two broad clusters of discursive resources and one contradictory (‘nurturing femininity’) discourse emerged. The first cluster engenders a sense of helplessness in the face of overwhelming power relations; the second enables the counsellors to foresee positive outcomes for their counselling. Implications for counselling include emphasising enabling discourses, highlighting multiplicities of gender, and wider-scale interventions.

- Description: The cultural and creative industries (CCIs) have been hailed as offering great potential to create jobs and to be socially inclusive. Since artistic success is defined by individual talent, or merit, the CCIs should be one sector that is especially open to, and appreciative of, social diversity in terms of race, class, cultural group and gender. However, as expected, recent studies in both the UK and the US have revealed that employment in the CCIs is heavily dominated by the middle classes, and is not as diverse in terms of other characteristics. Since the advent of democracy in South Africa in 1994, transformation of firm ownership, previously dominated by white people, to include more black, coloured and Indian/Asian-origin South Africans, has been an important part of achieving greater economic equality and social cohesion, as well as being more representative of the cultures of the majority of the population. Using data from a survey of 2400 CCIs firms in South Africa, this paper examines the extent to which the CCIs in South Africa have transformed in terms of ownership and employment. Comparisons are also made across the six UNESCO [(2009). Framework for cultural statistics. UNESCO Institute for Statistics. Retrieved from http://www.uis.unesco.org/culture/Pages/framework-cultural-statistics.aspx] “Cultural Domains” in terms of ownership, average monthly turnover and the number of full-time, part-time and contract employees. Results show some diversity in the industry, but significant differences between the Domains. Statistical analysis demonstrates that CCI funding policy in South Africa is sensitive to advancing the transformation agenda in that more transformed firms were shown to be more likely to have received some form of government grant as part of their income.

- Description: This dissertation offers a literary-thematic investigation based on a postcolonial approach to the representation of the Khoisan and their descendants. I restricted my scope to selected Afrikaans novels at the centre of critical attention between between 1994 and 2014. Earlier novels in this period under discussion are Dolf van Niekerk’s Koms van die hyreën (1994), Willem Kotze’s Tsats van die Kalahari (1994), Die spoorsnyer (1994), Olifantjagters (1997) and Gif (2001) by Piet van Rooyen, plus Karel Schoeman’s Verkenning (1996). Later texts in the focus are Duiwelskloof (1998) and Bidsprinkaan (2005) by André P. Brink, Dalene Matthee’s Pieternella van die Kaap (2000), Eben Venter’s Santa Gamka (2009) and most recently, the Hertzog prize winner of 2015, Buys by Willem Anker (2014). Themes central to South African literature will form the focus of the research, namely intercultural interaction between the first inhabitants of South Africa and missionaries, the question of land ownership, the language motif, and the role of religion (indigenous versus Western belief systems). Attention will also be on more specific issues such as the nature of the relationship between the Khoisan and the colonisers, the characterization of the Khoisan by the selected white authors, as well as other contemporary debates. The secondary objective of the study is to review the historical presence of the Khoisan and their descendants as reflected through the fictional lense of these authors writing over the last two decades, since democratization of the regime in 1994. My focus is particularly on the substantial cultural contribution of the Khoi and the San, as reflected through their representation in fictional works. The question will be posed whether the portrayal of Khoisan characters in novels after 1994 is different from the portrayal in fiction before 1994? My hypothesis is that in the fictional representation one finds a move towards restoration of their human dignity, yet the fact remains that all the authors are white. A different study of fictional works by coloured writers (whose numbers as Afrikaans authors grew substantially after 1994), investigating their representation of the descendants of the Khoi and the San, would in all probability yield radically different results, as the white authors imagine the characters and their consciousness from outside the community and the racial group, whereas the coloured writers belong to the community and the group that they portray.

- Description: The visit of the botanical artist, Marianne North, to South Africa during 1882 to 1883, although frequently referred to, has not received much close attention; nor has her account of the visit, in her ‘Recollections of a happy’ life, been set against the actual conditions she would have encountered. This paper attempts to flesh out at least part of that visit, specifically the weeks she spent in the Eastern Cape Colony and, more particularly, her visits to Port Elizabeth, Grahamstown and Port Alfred. What were these three centres like at the time? Who were the people she mentions? Where did she stay? How do her observations tally with other accounts of the period?.

- Description: Attempted repetition of a reported synthesis of fenchene from fenchol has afforded, in high overall yield, a mixture shown by spectroscopic and elemental analysis to comprise a pair of discrete rotameric systems of a novel 2-endo-2′-endo-difenchyl sulfite ester. The kinetics of the formation of these dimeric rotameric systems (I and II) has been explored experimentally, using 1H NMR spectroscopic analysis, and theoretically at molecular and quantum mechanical levels. Construction of a theoretical model has permitted calculation of rate constants for each of the steps, while modelling of the transition state complexes corresponding to the rate-determining steps for the formation of the rotameric systems I and II has revealed their independent access to further sets of interconverting rotamers.

- Description: Globally, one of the challenges in science education is providing equitable access to increasingly diverse learners in equally diverse learning contexts. In South Africa, science is taught to learners by means of English, which is the preferred language of instruction even if it is only spoken by 9.6% of the South African population. In the Eastern Cape, the majority of the population speak isiXhosa and the minority speak English. Parents of isiXhosa-speaking children often choose schools where English is the language of learning and teaching (LoLT) as they feel their children will have better career opportunities as English is considered to be the language of economic power. The aim of this study was to determine teachers’ and learners’ perspectives of language in science classrooms. To this end, a baseline study was conducted. A quantitative research method was used and data were collected through questionnaires. The research found that English is the preferred language for teaching and learning, even though the majority of the participants were isiXhosa home-language speakers. In addition, learners in South African whose home language is not English do not have the necessary language skills to cope with the switch to English as LoLT. Science teachers are therefore faced with two distinct challenges: firstly teaching content and secondly teaching the LoLT, if it is not the learners’ home language. The major difficulty experienced by learners when learning science is learning the language of science, as science is regarded as having a language of its own, with its own specific register and discourse. Thus, for many learners, learning the language of science is a challenge as it contains unfamiliar technical words and everyday words that have specialised scientific meanings (e.g. diagrams, procedures, table, current and force). English is seen as the language in which to explore these concepts. A conclusion that can be drawn is that English is regarded as the language in which to learn science thus reflecting the continued hegemony of English.

- Description: The incorporation of best practice in e-learning environments can increase the probability of success for companies and learners alike. By identifying and understanding the barriers that potential learners may face when interacting with e-learning products, the potential for e-learning failure may be alleviated. There are a variety of benefits that may be realised by companies incorporating e-learning opportunities into their management strategies. However, certain pedagogical principles, metrics and components need to be investigated and implemented in order for a corporate e-learning environment to be successful. The aim of this research is to prototype and evaluate a practical e-learning environment for software training (eLESTP) with e-learning components consisting of interactive learning objects that can guide the development and management of online training in the corporate context. The eLESTP is based on a theoretical contribution that is conceptualised in the form of an e-learning environment for software training (eLESTT). Hence, this study followed a research methodology that is appropriate for educational technologies, namely the Design-Based Research (DBR) methodology, which was applied in iterative cycles. Quantitative and qualitative data was collected by means of a case study, interviews, a focus group and survey. The proposed eLESTP underwent several iterations of feedback and improvement and the result is a real-world solution to the problem at hand. With the purpose of determining the success of corporate e-learning, the barriers and critical success factors for e-learning as well as evaluation criteria were explored. Interviews, a focus group and a survey were conducted in order to validate the investigated literature in a real-world context. Informal interviews enabled a better understanding of the organisational context of this study. The focus group was conducted with customers who were undergoing face-to-face training using conveyancing software developed by Korbitec. Many of the issues faced by learners identified in literature regarding e-learning in developing countries were identified by the participants from the case study. An e-learning survey was used to gather information regarding the intention of Korbitec’s customers to use e-learning as well as their satisfaction with using e-learning. From the survey, it was found that respondents were positive regarding intention to use and satisfaction toward e-learning usage. DBR Cycle 1: Problem Investigation and Proposal entailed the initial problem investigation by conducting a literature review, focus group and survey. DBR Cycle 2: Design Alternative 1 of this study involved a design alternative for eLESTP, namely Prototype 1. DBR Cycle 3: Design and Evaluate Alternative 2 involved the design and prototyping of Prototype 2 for eLESTP as well as the improvement of Prototype 2 through sub-cycles of testing and refinement. The suggestions for improvement were obtained from the relevant stakeholders at Korbitec who are content developers and subject-matter experts. The criteria used to evaluate the success of eLESTP, including its e-learning components, were synthesised and adapted from literature and a new set of evaluation criteria for e-learning environments in software training contexts was proposed. The evaluated eLESTP consists of the technology basis of the Modular Object Oriented Dynamic Learning Environment (Moodle), design guidelines for e-learning components, certification and competency-based training, pedagogical principles and best practice. Overall, eLESTP was positively received by various evaluator groups in formative and summative evaluations. The research results indicate that the use of an e-learning environment for software training purposes was useful and necessary.

- Description: The retention of persons on an HIV programme has been a global challenge. The success of any strategy to optimize adherence to anti-retroviral therapy (ART) depends on the intensive and effective adherence counselling and strategies. It is important to research whether persons receiving anti-retroviral therapy in public hospitals in Ghana are receiving the needed service that would optimize their adherence to the anti-retroviral therapy. Therefore, this study explored and described the experiences of healthcare professionals providing care, support and guidance to persons on ART at public hospitals in Ghana, as well as the best-practice guideline that could contribute to facilitating the ART adherence of patients. This study also explored and described the experiences of persons living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) on ART, regarding their adherence to the therapy. The study was organized into three phases. In Phase One: a qualitative, exploratory, descriptive and contextual design was employed. The research population included healthcare professionals, providing services at the HIV clinic at the public hospitals in Ghana, namely the Korle-Bu Teaching Hospital; the 37 Military Hospital and the Ridge Hospital. The healthcare professionals comprised of doctors, nurses, pharmacists and trained counsellors employed in any of the three public hospitals. Persons receiving ART at any of the three public hospitals were also part of the research population. Semi-structured interviews were conducted with healthcare professionals and persons receiving ART. Data were collected from healthcare professionals in relation to their experiences regarding the provision of ART services, their understanding of evidence-based practice and best-practice guidelines, as well as data on the experiences of persons receiving ART in relation to their adherence to the therapy. The data were analysed using Creswell’s six steps of data analysis; and the coding of the data was done according to Tesch’s eight steps of coding. Trustworthiness was ensured by using Lincoln and Guba’s framework which comprised credibility, transferability, dependability, confirmability and authenticity. Ethical principles such as beneficence and non-maleficence, respect for human dignity, justice, veracity, privacy and confidentiality were considered in the study. In phase two, the literature was searched by using an integrative literature review approach and critically appraising the methodological quality of the guidelines in order to identify the best available evidence related to adherence to ART. In Phase Three, a best-practice guideline for facilitating adherence to ART was developed for public hospitals in Ghana based on the findings of the empirical research of Phase One and the integrative literature review in Phase Two. The guideline was submitted to an expert panel for review; and it was modified, according to the recommendations of the panel.

- 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.

- Description: The Paleoproterozoic Transvaal Supergroup in the Northern Cape Province of South Africa is host to high-grade, Banded Iron Formation-hosted hematite iron-ore deposits and is the country’s most important source of iron to date. Previous studies suggest the origin of these iron ores to be ancient supergene, and that the ore forming process would have therefore pre-dated deposition of the basal Mapedi shales of the Olifansthoek Supergroup that unconformably overlies the Transvaal strata. The nature of the protolith to the ores has been suggested to be largely BIF of the Asbestos Hills Subgroup, and mainly the Kuruman BIF. The work presented in this thesis seeks to provide insights into the diversity of processes that are likely to have been involved during the genesis of these high-grade iron ores, in the context of constraining the pre-ore lithologies and the relative role of supergene-style, largely residual enrichment processes versus any possible metasomatic hydrothermal effects. This study had as primary focus the application of combined bulk and fraction-specific geochemical applications on representative iron-ore samples from four different localities in the Northern Cape Province, namely King/Khumani, Beeshoek, Heuninkranz and Hotazel. The collected samples show a variety of textures and also capture different pre-unconformity stratigraphic sections of BIF. The key objective was to assess whether the fraction-specific analytical results could provide any firm constraints for the origin of the ferrous and non-ferrous matrix fractions of the ores, namely whether they represent any combinations of protolith residue, allochtonously-introduced detritus or hydrothermally-derived material, and whether the results are comparable and consistent across all samples studied. In particular, constraints were sought as to whether the ore protolith was exclusively BIF or may potentially have contained at least a fraction of other lithologic types, such as shale; and whether there is sufficient evidence to support solely a supergene model for the ores or the data suggest other more epigenetic models of ore formation involving the action of hydrothermal fluids Bulk-rock geochemical analyses reveal the overwhelming dominance of Fe-oxide (as hematite) in all samples, at concentrations as high as 99 wt.% Fe2O3. Major and trace-element abundances of all samples were re-calculated assuming only iron addition from the postulated protolith (average BIF and shale), and the results revealed atypical enrichments in the iron ores by comparison to average BIF, and more shale-like relative abundances when normalised against the Post-Archaean Average Shale (PAAS). Specifically, BIF-normalised diagrams show relative enrichments by as much as 53-95% for Al2O3; 11-86% for TiO2; and 4-60% for P2O5. By contrast, PAAS-normalised values display enrichments of 1-3% for Al2O3, 0.2-3% for TiO2, and 3-13% for P2O5. Similar observations can be made for the greatest majority of trace elements when normalised against average BIF as compared to normalisation against PAAS. A suite of trace element that include alkali earths (e.g. Ba, Sr) and transition metals (e.g. Ni, Zn) show enrichments that are unrelated to the apparently detrital siliciclastic fraction of the ores, and are therefore linked to a possible hydrothermal input. Fraction-specific extractions were performed via the adaptation of existing dissolution protocols using oxalic acid (iron-oxide fraction) followed by HF digestion (silicate-fraction). The analyses of the produced aliquots using ICP-MS techniques, focused mainly on the REE abundances of the separated ferrous and non-ferrous matrix fractions and their comparisons to bulk-rock REE signatures. The results lend further support to the suggestion that the ore samples contain a predominant shale-like signal which does not directly compare to published REE signatures for supergene or hydrothermal BIF-hosted iron-ore deposits alike. The data therefore collectively point to a post-unconformity epigenetic hydrothermal event/s of iron ore-formation that would have exploited not only BIF but also shale as suitable pre-ore protolith.

- Description: Amidst the socio-economic meltdown in Zimbabwe, increased illegal mining activities on recently discovered diamond and gold deposits have given local people a source of livelihood. The problem of illegal gold mining is fast spreading through the Eastern Highlands and other parts of the country, as hundreds of artisanal gold miners swarm to the area, tearing up natural forests and plantations. Illegal mining operations are now rampant in the Chimanimani Mountains, a narrow belt located on the eastern Zimbabwean/western Mozambican border. The hilly and generally inaccessible nature of these mountains has preserved much of the native flora and fauna, including some endemic or near endemic animals and plants, and thus they are an important habitat. The highlands are also a crucial international catchment and a major water source for thousands of families dependent on agriculture and fishing for their livelihoods. However, with an estimated 400 000 miners now operating illegally in Zimbabwe, the cumulative mining activities represent a major threat to people’s livelihood security and to the integrity of this crucial catchment, habitat and associated river systems.

- Description: The literature shows that building collapses occur due to either management or operational failure. This Dissertation presents the causes of building collapse linked to management and operational lapses. A case study research on the Tongaat mall collapse in November 2013 forms the basis for the research. Through data collection that entails content analysis of official inquiry into the collapse and subsequent semi-structured face-to-face interviews among the participants in the collapsed building, major failures were identified. Salient findings show that the regulatory functions on the building project were compromised, and the inability to ensure that the project fulfils all enforcement and compliance requirements significantly enhances the existence of a work environment that led to two fatalities and 29 injuries. This study corroborates past findings that have flagged implementation as the weak link of H&S management in terms of construction regulations in South Africa. In other words, the benefits of adequate policies on paper can only emerge through applications on construction sites.

- Description: Using the in-silico approach, with ENCODE ChIP-seq data for various transcription factors and different cell types; we systematically compared the distance between the transcription factor binding site (TFBS) and the transcription start (TSS). Our aim was to determine if the same transcription factor binds at a different position relative to the TSS in a normal and an abnormal cell type. We compare distribution of distance of binding sites from the TSS; to make description less verbose we call this “distance” where there is no possibility of confusion. We used a case-control methodology where the distance between the TFBS and the TSS in the normal, non-cancerous or untreated cell type is the control. The distance between the TFBS and the TSS in the cancerous or treated cell type is the case. We use the distance between the TFBS and the TSS in the control as the standard. We compared the distance between the TFBS and the TSS in the case and the control. If the distance between the TFBS and the TSS in the control was greater than the distance between the TFBS and the TSS in the case, we can infer the following. The transcription factor in the case binds closer to the TSS compared to the control. If the distance between the TFBS and the TSS in the control is smaller than the distance between the TFBS and the TSS in the case, we can infer the following. The TF in the case binds further away from the TSS compared to the control. Our method is a screening method whereby we compare ChIP-seq data to determine if there is a difference in the distribution distance between the TFBS and the TSS for normal and abnormal cell types. We used the R package ChIP-Enrich to compare the distribution of distance between ChIP-seq peak and the nearest TSS. ChIP-Enrich produces a histogram with the number of ChIP-seq peaks at a certain distance from the TSS. The results indicate for some transcription factors like GM12878-cMyc and K562-cMyc there is a difference between the distribution of distance between the TFBS and the nearest TSS. cMyc has more binding sites within a distance of 1kb from the TSS in GM12878 when compared to K562. GM12878-CTCF and K562-CTCF have slight differences when comparing their distribution of distance from the TSS. This means CTCF binds almost the same distance from the TSS in both GM12878 and K562. A549-gr treated with dexamethasone is interesting because with increase dose of dexamethasone the distribution of distance from the TSS changes as well.

- Description: Quantitative measures of student performance fail to provide insight into underpinning constraints and enablements to access in science in higher education. This case study of a science foundation course uses Legitimation Code Theory as a theoretical frame and acquisition of recognition and realisation rules as an analytical frame to provide a depth empirical account of student access and success. Results indicate that access to the powerful science knowledge in the production (science) context is dependent on students recognising and realising the knower code of the learning context, which requires of them to be independent and autonomous learners. Such access is not afforded when students prior (school) learning-context relativist code clashes with the required university learning-context knower code. It is argued that a focus on the learning context could be key in enabling access to students whose educational background does not align well with that of the higher education context.

- Description: This thesis sought to explore how community volunteers could be recruited, supported and sustained to assist a community school operating in difficult socioeconomic conditions in achieving basic school functionality. Through a collaborative process, the participants in the study attempted to address a significant gap in the literature, namely how this could be achieved in a way that would be beneficial both to the community volunteers and to the school itself. Based on existing literature, the vast majority of South African schools are struggling to reach the basic functionality levels required in terms of legislation. My interest in this topic was piqued while serving as principal of one such school; hence the focus in this thesis on whether schools would benefit in terms of achieving functionality if they partnered with the communities in which they are located. However, communities are seldom actively involved in the schools and school activities on an ongoing daily basis. In this thesis, I argue for an opportunity for schools and the community to collaborate in a way that would be mutually beneficial. In this, I was guided by the School-Based Complementary Learning Framework (SBCLF) in gaining a greater understanding of how multiple stakeholders could support a school to obtain basic functionality. A key stakeholder is the community in which a school is located, and the multidimensional framework provided a framework to understand why the community would want to get involved in the school. Following a Participatory Action Learning and Action Research (PALAR) design, I recruited 15 community volunteers from the existing pool at my then school; some of whom had been volunteering for over twelve years. We formed an action learning set where we collaboratively sought to understand the processes and conditions needed to recruit, support and sustain community volunteers and their involvement in the school. From this action learning set emerged a key advisors’ set, comprising five members of the action learning set, who were entrusted with the responsibility of planning, preparing and analysing the action learning set meetings. Transcripts and visual artefacts from the action learning set meetings and a focus group meeting of the school management team were analysed to generate data, complemented by secondary sources, such as documents. This participatory approach to data generation allowed the voice of every participant to be heard; agency was increased through active participation; and the sense of affiliation to the group was deepened. The iterative design of the research process further ensured that the participants also engaged in a critical discourse analysis of the emerging data, of which the trustworthiness was enhanced through the use of dialogic and process, catalytic, rhetoric, democratic and outcome validity. The emergence of the data through this collaborative engagement was underpinned by the ethical values of mutual respect; equality and inclusion; democratic participation; active learning; making a difference; collective action; and personal integrity. The findings revealed that community volunteers did add immense value to the school by supporting teaching and learning processes. However, the community volunteers also harboured expectations of material support and opportunities to develop skills. In addition, the study revealed that the hierarchical culture and structures present in most South African schools need to become more democratic and collaborative, with those working to make the school more functional, including community volunteers, being valued, acknowledged and supported. The participants also constructed their understanding of what a community school should be and do and how it should serve the interests of the children from the community. A process model was constructed from these findings regarding on ways to recruit, sustain and support community volunteers involved in community schools, specially designed so that schools could adapt it to suit individual contexts. This study is unique; I am not aware of any similar study ever having been conducted in a community school in South Africa. Furthermore, the collaborative approach used in the study helped ensure that the methodology used could be of value to principals and other school stakeholders in addressing the various complex challenges that confront schools in these contexts. Also, the findings will add to the theoretical body of knowledge around volunteerism, especially in difficult socioeconomic conditions.

- Description: Literature has highlighted the importance of university-community partnerships in servicelearning (SL) as a vehicle for conducting a mutually beneficial service-learning programme (Dorado & Giles, 2004). This research aimed to investigate factors influencing a SL partnership through the insights of a particular community partner. Based on a case study of a rural school in the Eastern Cape, three community partners perceptions were obtained through in-depth semi-structured interviews. Thereafter, thematic analysis was used to analyse the data using Braun and Clarke’s (2006) six phase guide. Three main theme’s emerged from the data that shed light to the key issues shaping community partners perceptions. These were centred on the effects of apartheid including resources, geographic location, and level of commitment from the university. The findings of this research brought forward the importance of awareness of context, responding to the context and commitment displayed in the partnership. This research further highlights the need for community partner’s perspective in literature.

- Description: In order for the proceeds of unlawful activities to be completely dislodged from the criminals’ hands, the latter should be effectively deterred from allowing their assets to be used to execute or facilitate the commission of offences. When properly exacted, in the interests of justice and within the existing constitutional framework, the legal process known as asset forfeiture should ensure that crime never pays. Asset forfeiture refers to both criminal forfeiture, which is conviction based following the United Kingdom asset forfeiture regime and civil forfeiture, which is non-conviction based following the United States of America one.2 Chapter 5 provisions of the Prevention of Organised Crime Act3 (hereafter POCA) provides for court, Basdeo M – Search, Seizure and Asset Forfeiture in the South African Criminal Justice System: Drawing a Balance between Public Utility and Constitutional Rights (2013) LLD, University of South Africa in Chapter 5 where a comprehensive comparative study of SA POCA and United States of America’s asset forfeiture and origin is undertaken. 3 Act 121 of applications for a restraint, confiscation and realisation for the recovery of proceeds of unlawful activities. The restraint is invoked when a suspect is to be charged or has been charged or prosecuted, there are reasonable grounds to believe that a conviction may follow and that a confiscation order may be made. Chapter 6 provisions of POCA provide for court applications for preservation and forfeiture order targeting both the proceeds of unlawful activities and removal from public circulation of instruments or assets used in the commission of offences where the guilt of the wrongdoer is not relevant. POCA has a Schedule with 34 items setting out examples of offences in relation to which civil forfeiture may be invoked. When the State discharges this noble professed task in the name of public safety, security and crime combating, legal challenges arise. This is more so within a constitutional democratic context where both individual and property rights are enshrined and protected. This study deals with some of these challenges. To the mind of a legal researcher, the law of asset forfeiture is, in this process, moulded and developed. South Africa (a developing country), Canada and New Zealand (developed countries in the north and southern hemispheres) have constitutional democracies. They also have asset forfeiture regimes, which attracted the attention of the researcher. The question is: can the developing country learn some best practices from the developed countries in this particular field? It would be interesting to establish this and the level of development of this field in the three countries under study. South Africa, with no federal government, has nine Provinces, single asset forfeiture legislation5 (combining both criminal forfeiture i.e. restraint, confiscation and realisation applications and civil forfeiture i.e. preservation and forfeiture applications), and a criminal statute6 applicable to all such Provinces. It also has, like Canada and New Zealand, pockets of asset forfeiture provisions embedded in various statutes. There is only one asset forfeiture office under the umbrella of the National Prosecuting Authority.7 It has branches8 in the Provinces, invoking the provisions of POCA, since 1999. It is not part of the police department. The researcher joined the South African Port Elizabeth branch in March 2003, Bloemfontein, Kimberly and Mmabatho branches from 2010 to 2011, July 2012 onwards in the Port Elizabeth and has practical experience in this regard.

A comparative analysis of the new behaviours and terms introduced in the understatement penalty table in section 223 of the Tax Administration Act

- Description: The Tax Administration Act became effective on the 1 October 2012 and in Chapter 16 introduced the understatement penalty regime which replaced section 76 of the Income Tax Act. The understatement penalty is calculated by applying a percentage in terms of the table included in section 223 of the Tax Administration Act to the shortfall in tax giving rise to the imposition of the penalty. There are five behaviours reflected in the understatement penalty table in section 223, namely, “substantial understatement”, “reasonable care not taken in completing return”, “no reasonable grounds for tax position taken”, “gross negligence” and “intentional tax evasion”. “Substantial understatement” is the only behaviour defined in the Tax Administration Act. Section 222(1) of the Tax Administration Act requires SARS to impose the penalty reflected in the table in the event of an “understatement”, unless the “understatement” results from a “bona fide inadvertent error”. The term “bona fide inadvertent error” is not defined in the Tax Administration Act; neither is the term “obstructive”. The Memorandum on the Objects of the Tax Administration Laws Amendment Bill confirmed that guidance would be developed in this regard for the use of taxpayers and SARS officials. This guidance has not yet been released. Media reports express the view that the lack of definition of the behaviours is problematic for both SARS and taxpayers as the table is new and there is still room for interpretation and understanding of the meaning of each of the behaviours. The primary goal of this study was is to obtain a better understanding of the meaning of the new behaviours and terms introduced in the understatement penalty table. In addressing this main goal, the penalty tables and behaviours in legislation in New Zealand were compared to South Africa’s understatement penalty. The similarities and differences between the understatement penalty imposed in terms of Chapter 16 of the Tax Administration Act and the additional tax previously imposed in terms of section 76 of the Income Tax Act were also discussed to determine whether this would be of assistance in enabling a better understanding of the meaning of the behaviours and terms in section 223. Guidance on the interpretation of the various behaviours and terms was developed and a definition was proposed for the meaning of “bona fide inadvertent error” and “obstructive” to assist in the objective and consistent application of the understatement penalty table in relation to each shortfall identified. The proposed definition for “bona fide inadvertent error” is as follows: “An honest mistake made or simple oversight, which the taxpayer was not aware of, despite taking reasonable care and displaying a prudent attitude while making a genuine attempt to comply with all applicable tax obligations.” The definition for “obstructive” is proposed as: “Deliberately interfering with, causing difficulties (impeding) or delays in, or preventing the progress of a SARS audit or review.”
