- Description: Many graduate software developers are not competent in secure programming, resulting in risks that are caused by vulnerabilities in the application code of software applications. These graduate software developers are equipped with programming knowledge and skills from universities, however, these software developers are rarely equipped with secure programming knowledge and skills from the undergraduate level. Although there are various techniques for writing secure code in the current body of knowledge, these techniques are rarely fundamental components of a computing curriculum, resulting in incompetent graduate software developers. The security aspect of software applications, is considered as an important aspect that can reflect the ability of a system to prevent data exposures and loss of information. For businesses that rely on software applications to keep operations running, a failure of a software application can stop production, interrupt processes, and may lead to data breaches and financial losses. This research argued that secure programming education needs to be included across computing curricula, and thus, the primary objective of this dissertation was: To develop a framework for integrating secure programming principles into undergraduate computing curricula. It proposes a framework for the incorporation of secure programming principles into undergraduate computing curricula, through a step-by-step approach. This framework includes the identification of application risks and secure programming practices as they relate to each other, and to the basic programming concepts taught to undergraduate students. It specifically aims to improve the security of software applications developed in the .Net framework environment. The main research methods used in this study included a literature view, thematic content analysis, argumentation, and modelling.

- Description: The South African Government has institutionalised a Corporate Governance of ICT Policy Framework which was developed by Department of Public Service and Administration (DPSA). The framework has adopted some elements of KING III, ISO 38500 and COBIT. Consequently, it is now a requirement by the South African Government that all its entities must adopt this framework. Nevertheless, it is not clear how government has emphasised this alignment in such entities. The problem statement in this study was that Randwater is unable to realise full value of the investment in IT/IS because there is misalignment between IT objectives or deliverables and the corporate objectives. This study sought to identify a suitable framework which meets the ICT policy criteria as set out by the DPSA, which will facilitate the alignment between corporate objectives and IT/IS objectives at Randwater. This was achieved through the development and refinement of the artefact through the various iteration phases. Additionally, an online survey was used to collect data from a focus group comprising IT experts and senior management at Randwater. The Information Technology Governance Institute Framework was employed to assist in the development of the questions. The survey results were utilised during the validation of the artefact produced by this research study in a workshop. The findings were then linked with the related literature which either supported or rejected the findings through discussions on the literature and thereafter conclusions were made based on these findings. Furthermore, a literature review was conducted to gain a better understanding of what has been done in the field of research in order to assist in defining the problem that this research seeks to solve so as to inform the development of design characteristics. The research process employed the Nelson Mandela University – Design Science Strategy Methodology referred to as (NMU – DSSM) with the goal of developing an artefact in the form of a framework. The research process entailed studying the existing literature and analysing the aspects relating to corporate governance, IT governance, frameworks, and strategies to be able to measure the degree of alignment. The phases of designing the artefact were analysis, design, evaluate, validate and diffuse phases. The final artefact developed was a framework that incorporated the principles of King IV and ISO 38500 in corporate governance and ICT goals alignment. The final artefact also embedded transparency, accountability and security as important elements in the implementation of the artefact. The survey findings were instrumental in the development of the artefact that brings alignment between business strategy and IT objectives at Randwater. From the findings, in terms of IT flexibility, it was revealed that the interrelated parts of the system at Randwater were modular. It was also concluded that there is lack of communication about the manner in which the components of the information systems are organised and integrated in order to allow for rapid changes and that the organisational IT infrastructure and applications were loosely coupled. The findings further revealed that the business had established corporate rules and standards for hardware and operating systems to ensure platform compatibility. It was also revealed that organisational IT applications were developed based on compliance guidelines. In terms of IT-enabled dynamic capabilities, it was revealed that IT systems at Randwater are not capable of scanning the environment and identifying new business opportunities and are not capable of anticipating discontinuities arising in the business domain by developing greater reactive and proactive strength. It was also revealed that it was concluded that IT systems were capable of achieving strategic alignment between IT flexibility and dynamic capabilities. Therefore, design science was the ideal research paradigm towards addressing the research problem and the artefact designed was a viable research contribution. The significance of the study was that it contributed to the development of technology-based solutions to an important and relevant business problem of alignment of business strategy to IT goals. The design evaluation, the utility, quality, and efficacy of the final design artefact was rigorously demonstrated via well-executed evaluation methods. The study also contributed to the literature

- Description: The Cactaceae family comprises 15 genera and nearly 2000 species. With one exception, these are all native to the Americas. Numerous cactaceous species are invasive in other parts of the world, resulting in considerable damage to ecosystem functioning and agricultural practices. The most successful biological control agents used to combat invasive Cactaceae belong to the Dactylopius genus (Hemiptera: Dactylopiidae), comprising eleven species. The Dactylopiidae are exclusively cactophagous and are usually host-specific. Some intraspecific lineages of dactylopiids, often referred to as `biotypes', also display host-specificity, and are used to control particular species of invasive Cactaceae. To date, two lineages within Dactylopius opuntiae (`ficus' and `stricta'), and two within D. tomentosus (`cholla' and `imbricata') have been released in South Africa to control Opuntia ficus-indica and O. stricta, and Cylindropuntia fulgida and C. imbricata, respectively. The `californica var. parkeri' lineage is currently under consideration for release in South Africa for the control of C. pallida. Australia has already released these five lineages, and approved the release of an additional three in 2017; namely D. tomentosus `bigelovii', `cylindropuntia sp.', and `acanthocarpa x echinocarpa'. Many of the Dactylopius species are so morphologically similar, and in the case of lineages, identical, that numerous misidentifications have been made in the past. These errors have had serious implications, such as failed attempts at the biological control of cactus weeds. This thesis aimed to generate a multi-locus genetic database to enable the identification of the species and lineages in the Dactylopiidae family, and to test its accuracy. Seven species were included in the analysis, including two lineages within D. opuntiae and six within D. tomentosus. Genetic characterisation was achieved through the DNA sequencing of three gene regions; namely mitochondrial 12S rRNA and cytochrome c oxidase I (COI), nuclear 18S rRNA, and fragment analysis using two inter-simple sequence repeats (ISSRs). Nucleotide sequences were very effective for species-level identification, where the 12S, 18S, and COI regions showed 100%, 94.59%, and 100% identification accuracy rates, respectively. Additionally, the 12S and COI markers distinguished between half of the D. tomentosus lineages (`californica', `cholla', and `imbricata'), with identification accuracies of 100%. The `echinocarpa x acanthocarpa', `bigelovii', and `cylindropuntia sp.' lineages formed one clade. None of the DNA genetic markers showed a separation between the `ficus' and `stricta' lineages within D. opuntiae. Fragment analysis through the use of ISSRs provided higher-resolution results, and addressed this gap by showing a well-supported separation between the two lineages, and between wild populations collected in the Eastern Cape Province in South Africa. The identification accuracy of the `ficus' and `stricta' lineages was 81.82%. This is the first time that a method has been developed that can distinguish between these lineages. An additional component of this thesis was the creation of three user-friendly R-based programs to assist with: 1. ISSR data processing. 2. The identification of query Dactylopius nucleotide sequences relative to the gene databases created here. 3. A graphical user interface (GUI) version of the R package `SPIDER', which is useful for the assessment of the accuracy of genetic barcode data. A successful biological control programme relies on the correct identification of the agent in question, and so it is imperative that cactus biological control practitioners are able to distinguish between Dactylopius species and lineages in order to release the most effective ones onto target Cactaceae. The laboratory protocols reported, and data processing tools created here, have largely addressed this need and offer valuable practical applications. These include: 1. The flagging of potential new species, cryptic species, and lineages of dactylopiid species released as new biocontrol agents. 2. Validating the identifications made by taxonomists based on morphology. 3. Confirming to which species, and, where applicable, to which lineage, a field-collected sample belongs. 4. Identifying hybrids resulting from lineage crosses. Ensuring that the correct Dactylopius species are utilised for biological control will improve the control of invasive Cactaceae and protect biodiversity and agricultural productivity.

- Description: Microbialite accretion takes place via either mineral precipitation, the trapping and binding of mineral and sediment grains, or a combination of the two. Recently, the geochemistry of carbonate deposits, including microbialites, has been used to reconstruct palaeoenvironments and infer biogenicity. Numerous modern stromatolite (layered microbialites) systems are located on the southern African coastline and are formed predominantly by mineral precipitation with minor detrital input. In order to better understand the environmental and biological processes influencing the formation of microbialites, the geochemistry of southern African coastalstromatolites is examined. This is done by a spatial comparison of the hydrochemistry as well as the major and trace element geochemistry of various coastal stromatolite systems. The influence of the underlying geology on the composition of the stromatolites forms a particular focus of the study. In addition, the effect of metazoans on the micro-fabrics and sediment incorporation into the stromatolite matrix is assessed. Finally, the trace element geochemistry of active, inactive, and ancient stromatolites is compared with a speleothem sample in order to test the validity of using trace elements as a means to determine biogenicity of deposition. Results show that the bulk geochemistry of the South African stromatolites is not a simple function of the associated bedrock lithologies, although certain parallels do exist. It was found that metazoans indirectly influence sediment incorporation by increasing porosity and thereby accommodation space for detrital input. Furthermore, trace element signatures could not be directly attributed to microbial influence in the deposition of the carbonates. Ultimately, this study provides valuable insights into the formation processes of the active South African stromatolites and the use of trace elements as a geochemical tool to investigate the evolution of life and determine past environmental conditions.

- Description: Many University programs offer a course in either basic or intermediate statistics as part of the degree requirements prior to graduation (McGrath, Ferns, Greiner, Wanamaker and Brown, 2015). These statistics or quantitative research methods courses are integral in helping students gain vital skills in analysing quantitative data. Research (Schau, Stevens, Dauphinee, and Del Vecchio, 1995) does however indicate that most students have a perfunctory disposition towards these courses. My study sought to particularly investigate attitudes towards statistics and quantitative research methods amongst a sample of 61 postgraduate Psychology students at Rhodes University undertaking a ‘Quantitative Research Methods’ course as part of their degree offering. A mixed methods approach was used to investigate students’ attitudes towards statistics and quantitative research methods. The Survey of Attitudes Toward Statistics (SATS-36) (Schau, 2003) captured student’s attitudes towards statistics using a Likert Scale instrument; whereas detailed qualitative interviews accentuated findings from the SATS-36. Key quantitative findings from the SATS-36 including students’ perceptions of statistics being a difficult course as well as students having a low affect towards statistics are detailed. Key qualitative findings related to why students experience statistics anxiety such as students’ (1) fear of failing statistics, (2) The late introduction of statistics in the Psychology curriculum, and (3) The role of educator/s in alleviating or promoting feelings of statistics anxiety are noted. The significance of these findings as well as the contributions of the study to the teaching and learning of statistics and quantitative research methods courses at Rhodes University are explored, in light of other studies on the topic of statistics anxiety and attitudes towards statistics/ quantitative research methods.

- Description: Breast cancer is the most common cancer amongst women and one of the deadliest. Various modalities exist which image the breasts, all with a focus on early detection; thermography is one such method. It is a non-invasive test, which is safe and can be used for a wide variety of breast densities. It functions by analysing thermal patterns captured via an infrared camera of the surface of the breast. Advances in infrared and mobile technology enable this modality to be mobile based; allowing a high degree of portability at a lower cost. Furthermore, as technology has improved, machine learning has played a larger role in medical practices by offering unbiased, consistent, and timely second opinions. Machine learning algorithms are able to classify medical images automatically if offered in the correct format. This study aims to provide a model, which integrates breast cancer detection, thermal imaging, machine learning, and mobile technology. The conceptual model is theorised from three literature studies regarding: identifiable aspects of breast cancer through thermal imaging, the mobile ecosystem, and classification using machine learning algorithms. The model is implemented and evaluated using an experiment designed to classify automatically thermal breast images of the same quality that mobile attachable thermal cameras are able to capture. The experiment contrasts various combinations of segmentation methods, extracted features, and classification algorithms. Promising results were shown in the experiment with a high degree of accuracy obtained. The successful results obtained from the experimentation process validates the feasibility of the model.

- Description: Education policies are designed to structure and direct the content and process of the education that citizens receive. This includes the advancement of the Education for Sustainable Development (ESD) policy in formal school curricula. If effectively implemented, ESD can be a significant educational intervention in southern African countries’ development trajectories. ESD incorporates the environmental, social and economic pillars of Sustainable Development and it has the potential to curb issues such as poverty reduction, climate change, biodiversity loss and unsustainable patterns of consumption and production. This qualitative case study investigated factors that have historically shaped, and currently shape, the emergence of ESD implementation in the Senior Primary English curriculum in the Khomas Region of Namibia. As a critical realist enquiry, the study sought to go beyond interpretations of the empirical to identify causal mechanisms in the domains of ‘the actual’ and ‘the real’. The study was guided by Margaret Archer’s theory of Morphogenesis / Morphostasis and her methodological tool of ‘analytical dualism’. The case record consisted of educational documents, teacher questionnaires and semistructured interviews. The morphogenetic approach highlighted how the implementation of ESD through the Senior Primary English curriculum from 1990 to 2018 was conditioned by the interplay of social and cultural structures and mechanisms and human agency, particularly teachers’ agency. The study revealed that although ESD implementation has emerged in the Senior Primary English curriculum, its emergence is not synchronous with the structural and agential entities. The findings point to a policy-structure mismatch which has relevance for policy makers, practitioners and other ESD stakeholders. The significance of this study is that it stands to fill a research gap regarding ESD implementation in Namibia’s Senior Primary English curriculum. The study makes recommendations for tangible ways to strengthen ESD practice in Senior Primary English teaching in Namibia such as increasing professional development opportunities to orientate teachers to ESD, strengthening networks that can build teacher agency in relation to ESD, and promoting a theme-based approach to ESD practice in English Language teaching.

- Description: In response to a demand for quality children’s picture books written and published by South Africans for local children, Book Dash – a South African non-profit organisation – has devised a publishing model in which they produce high quality children’s picture books in a twelve-hour period. Their aim is to publish books that represent a diverse range of South African children. However, while their objective is to create books that are representative of many races, this representation happens through gendered characters. In this thesis, I explore the representation of gender in Book Dash’s picture books. I use a combination of visual social semiotics, narrative theory, and critical discourse analysis, specifically focusing on the gendered ways in which the characters are represented. My analysis of these books shows how complex it can be to contest regimes of representation that work to fix patriarchal discourses and gender inequality. My findings reveal a paradox in the representation of gender norms in female characters, as some girl child characters are represented in roles that challenge gender norms, while female adult characters are consistently represented as conforming to the patriarchal feminine ideal. There is also a notable lack of father figures in these books. Such portrayals may contribute to the perpetuation of patriarchal discourses and gender inequality, particularly if these books are held up as examples of equality.

- Description: Public awareness poster campaigns are an often-used method for raising awareness about, and engaging audiences on the topic of rape and other forms of sexual violence (Potter, 2012). However, poster campaigns, as social artefacts, operate in a public arena in which numerous discourses about a phenomenon are produced, reproduced and interact with each other, with sometimes unintended/unanticipated discursive consequences (Böhmke, Bennie, Minnie, Moore, Pilusa & Pollock, 2015). How messages aimed at raising awareness of sexual violence are framed has the potential to reproduce dominant social narratives and gendered subject positions in ways that reinforce notions of men as active sexual agents and potential perpetrators, and women as sexually passive and potential victims (Gavey, 2005). Other approaches, such as bystander intervention, seek to move away from a focus on victims and perpetrators to emphasise the role that community members can play in risk detection, safety promotion and the prevention of sexual violence (McMahon & Banyard, 2012). Since a range of possible messages about sexual violence can be communicated through poster campaigns, it is important to critically examine the content and orientation of campaign material. This study focused on intended audience views regarding messages about sexual violence contained in anti-sexual violence poster materials. The purpose was to collaborate with a selected audience to better understand which messages are effective and which strategies of communication are perceived to be less so. Through the use of Q-methodology, volunteer participants were invited to express their opinions in relation to messages about sexual violence from a range of posters from several international campaigns. The analysis focused on uncovering the discursive subject positions that participants’ express in their attitudinal responses to the poster messages, providing not only a description of these positions, but also illustrating the level of resonance that the poster messages may find with intended audiences. The aim of the study is to potentially inform the development of more focused campaign material, tailored to the specific context from which participants were drawn. Analysis shows clear patterns of audience resistance towards stereotypical representations of sexual violence and messages that are geared towards the simple prohibition of behaviours. The findings highlight the need for the development of alternative strategies of engagement that focus on specific engagement with understandings of sexual violence in the context of intimate and/or acquaintance relationships and which are aimed at inviting audiences to take up a position in relation to sexual violence phenomena that troubles the reproduction of received notions of gendered subjectivities and (hetero) sexuality

- Description: Music Performance Anxiety (MPA) refers to the potentially debilitating anxiety experienced before and/or during the public performance of music, despite adequate preparation. MPA is generally treated by means of drug therapy, cognitive behavioural therapy, psychoanalysis or various relaxation techniques. This research aims to present a different approach to dealing with MPA, based on a reconceptualisation of the concept. As a result, it attempts to unpack all three concepts inherent in the term from both a psychological and philosophical viewpoint. The study used autoethnography as a methodology, as I wished to explore my own lived experience of MPA and anxiety in general, in conjunction with that of my two participants, two other student Western Art music performers, and how our methods for confronting MPA within the performance context itself suggests a more complex understanding of performance and MPA than is reflected in the current literature. Thus the data was collected from two first-person interviews as well as a self-reflective written account. The results of the analysis were that existential anxiety is potentially a contributing factor to MPA, and that performance itself can potentially provide the very means for overcoming not only MPA, but all forms of anxiety, due to the cathartic quality of music as well as performance, especially when the liminal or interstructural, nature of performing and its ritualistic function is explored. This exploration reveals the world and self-disclosing nature of agency and Play, or the potential within experiences to resolve conflicts and reveal otherness. This requires a degree of existential courage, or an affirmative response to the unknown, which is more relational than the definition suggests. In conclusion, this study reconceptualises MPA as a potentially potent existential experience, and that the anxiety in response to it is considered as a reaction to the catharsis inherent in being an agent, rather than merely as an obstacle to be controlled.

Understanding millennial worldviews could provide insights for policy interventions for sustainable use of the marine and coastal environment. The aim of this research is to design, develop and evaluate an appropriate social media method to elicit millennials’ worldviews on the coastal and marine environment. The methodology used for the research was Design Science Research (DSR), which is a legitimate approach to conducting research in the field of Information Systems. The methods used were a literature review, interviews with social media experts and Social Media Influencers (SMIs), and a focus group discussion with researchers from the field of social sciences. The proposed artefact (the method) can be used to provide guidance to researchers for engaging and eliciting opinions and worldviews of millennials on social media. The method includes a Social Media Influencer Model that illustrates the relationship between SMIs’ characteristics and techniques for engaging the public, and a Social Media Analytics (SMA) Process model that can guide researchers through the steps of eliciting worldviews from the public. Although there are several SMA techniques that can be used, the proposed method uses sentiment analysis as an SMA technique for deriving sentiments from social media data. The method was evaluated by researchers who require a social media method for eliciting millennials worldviews. The findings confirmed some of the techniques identified in literature as well as some additional techniques and processes. It was also evident that using this method could assist researchers for data collection and specifically to obtain worldviews on the marine and coastal environment. The contribution of this study is an artefact that fulfils the need for a social media method for data collection that is more convenient for researchers and millennials and can guide researchers through the steps of eliciting worldviews from the public.

- Description: Urban domestic gardens are an often overlooked component of urban green infrastructure, despite their potential to contribute to the preservation of urban biodiversity. As opposed to public greenspaces, private gardens are individually owned and managed, thus act as social-ecological systems, where the cumulative actions of urban residents can scale up to influence ecological patterns and processes on a larger scale. The diversity of fauna and flora within urban gardens provide a range of ecosystem goods and services, as well as less tangible benefits in the form of recreation, education and culture. However, little is known about the contribution of urban domestic gardens to urban biodiversity and its potential conservation value in South Africa. This study investigated urban domestic gardens along a socio-economic gradient in two medium-sized towns, Grahamstown and Port Alfred in the Eastern Cape, South Africa. This study found distinct differences among urban resident garden management practices as well as the avifauna which were seen within the gardens across the socio-economic gradient. The Garden Management Intensity index was higher within affluent households compared to other socio-economic levels, with subsequent management scores not differing statistically along the gradient. While there was variation within garden management practices, as well as the number of residents who participated in supplementary bird feeding, little variation was seen in the activities which were enjoyed by the residents, indicating numerous benefits the garden environment provides for all urban residents. The bird community composition along the socio-economic gradient displayed patterns directly reflecting the “luxury effect”, where households with a higher socio-economic status had harbour gardens with greater levels of biodiversity. This study showed that affluent gardens displayed far greater diversity, richness and abundance of urban birds. Multivariate analyses confirmed the patterns by highlighting a distinct bird community in the affluent zone, compared to other two socio-economic zones, which housed a second bird community. Furthermore, the main driver of the bird community composition was dominated by vegetation complexity, most notably tree cover within the gardens. Therefore, this study highlighted that patterns of ecological inequality are highly evident in medium-sized towns in South Africa, where older, affluent suburbs households display greater diversity and abundance of birdlife, compared to subsequent socio-economic zones within the study. Prioritisation with regards to the benefits a garden environment brings to urban residents in terms of a connection to nature, access to urban greenery, and relationship to urban wildlife is vital and should be promoted and planned for across all socio-economic zones.

- Description: It is always assumed when you have a white surname that you have a white lineage or your forefathers were white, and that was always my struggle in school to explain the meaning of my surname and where it came from. Not only European surnames used by amaXhosa are difficult to explain but also many isiXhosa surnames are very hard to break down and explain. This is because many word from th e isiXhosa language, that are used in surnames are no longer used and if one does not know the history of certain names then it would be difficult to know the meaning of a surname or misinterpret its meaning to the modern words of isiXhosa that we know. S urnames are not of African origin, they came from the West, but because of colonialism surnames were enforced on African people. Most of the surnames they used, are said to be names of their forefathers (ancestors), and there is a small amount or none that links to femininity in these surnames. Surnames are part of naming and naming is part of onomastics. Naming is a very important tool used among various African cultures to convey certain messages, either to an individual, family members or a community. On omastics is multidisciplinary in nature. It can be approached from different perspectives. These include linguistic, historical, sociological, philosophical, economical and other perspectives. This research looks at the depth of certain amaXhosa surnames and even their links to other names like, nicknames and clan names etc.

- Description: Gender-based violence more especially sexual violence towards women is one of the biggest social issus affecting South Africa including higher institutions of learning, universities in this context. In recent years, we have seen students in universities protesting sexual violence demanding universities to improve their ways of dealing with this violence. The motivation behind this thesis is the notion that sexual violence is a women’s issue and how most men in our communities and universities do not involve themselves in campaigns that are designed to end sexual violence towards women. There is an assumption that women should be the ones fighting against sexual violence because it affects them when in fact sexual violence affects everyone and more importantly, is mostly perpetuated by men. Therefore, the main purpose of this thesis was to sociologically analyze the involvement of men in campaigns against sexual violence towards women and the aftermath of the #RUReferenceList protest that took place at Rhodes University in 2016. This protest started immediately after a list of students who were said to be alleged sexual perpetrators was published online. Attached to this primary objective, the sub-goals that informed the entire study were to investigate how the involvement of men in the #RUReferenceList protest has contributed to challenging rape culture at Rhodes University. Also, to investigate if there are any ongoing campaigns and/or projects that includes men and that are still addressing the issue of sexual violence towards women. There is however, a dearth of research on the involvement of men in campaigns against sexual violence in South Africa. Therefore, it was difficult finding existing literature that touches on the involvement of men in campaigns against sexual violence towards women particularly in the context of universities. This thesis was conducted within the premises of Rhodes University through a qualitative research approach in a form of in-depth interviews. Five participants were selected through purposive sampling which included the Chair of the Gender Action Forum, one former student representative council member, a sub-warden from a male residence and two students. The findings of this research are not the full representation of the entire university but opinions and perspective of the participants that were interviewed. Their opinions and perspectives have a potential of contributing to the factors and reasons as to why majority of men have not engaged themselves in issues of gender-based violence or involved themselves in campaigns against sexual violence towards women.

A sociological analysis of the sex education of young adult white womxn and their understandings and practices of ‘Safe Sex’

- Description: This research sets out to examine the experiences and perspectives of young adult white womxn regarding their respective sex education. This is in terms of how sex education may shape and influence sexual practices. The relevance of exploring the sex education of this group is to gain an understanding of how constructions of sex education may facilitate the negotiation of sexual practices, particularly as these practices relate to the negotiation of ‘safe sex’. This involves an exploration of definitions of ‘safe sex’ as well as an examination of the various sources of sex education. This research argues that sex education has been socially constructed within a ‘heterosexual matrix’ where both gender identities and sexuality are constructed in heterosexual terms in accordance with compulsory heterosexuality. Furthermore, that sex education as well as understandings and practices of ‘safe sex’ intersect with other social categories such as race, gender and sexuality. Much of the sex-related research conducted in South Africa focuses on people of colour, as a result very little is known about the sexual behaviours and practices of the white demographic. This research accounts for the absence of analysis of sexual practices and behaviour among white people by examining the sex education and sexual practices of young adult white womxn between the ages of 19 and 24. The research observed key sources of sex education which included parents, schools, religious institutions and the internet. Findings indicate that the sex education of participants reflected ideals of heteronormativity and misogyny which were found to directly influence their understandings and practices of both sex and ‘safe sex’. Furthermore, that the sex education participants received has ultimately failed to promote ‘safe’ sexual practices.

- Description: Information is a critical asset in any organisation and its management, including the associated technological channels, requires the attention of decision-makers to ensure that information assets are utilised for the intended purposes. Therefore, decision-makers need to have appropriate governance oversight on technology that produces information and information itself. Over the years, the governance of ICT has been adopted in the public sector given the fact that state funding received from tax collections is utilised to invest in IT solutions with the intention of expediting service delivery and increase productivity. The purpose of this treatise was to identify the root causes of why the department is not implementing Corporate Governance of ICT successfully despite the fact that most good controls do exist. The research revealed that there is insufficient budget to implement ICT projects coupled with inadequate ICT staff to implement ICT strategy. Furthermore, it cited a lack of ICT governance skills with ICT Strategic Committee members who are tasked with pioneering ICT governance. This weakness relates directly to other identified weaknesses such as end-user resistance to adopt ICT projects and a lack of project management function in the department.
