- Description: The present study intends to explore the psychological implications on the university students who grew up in households where their biological fathers are absent. Most studies associate the absence of the biological fathers with psychological challenges which, among others, include negative emotions such as anger, challenges with maintaining romantic relationships and tend to perform poorly at school. Such research on absence of fathers tends to privilege the biological father discourse in its analysis and often mentions in passing the role played by ‘other’ family members as ‘fathers’. Since during data collection participants kept on referring to the role of other family members or father figures, the study then expanded its scope of inquiry to include this phenomenon. Semi-structured face to face interviews were used to collect data from five university students and thematic analysis was used for data analysis. Psychoanalytic theory was used to specifically to understand or conceptualize the psychological implications on participants caused by the absence of the biological father. Black Social organization theory and Structural Functionalism theory were used to conceptualize the role of other family members/families or father figures in participants’ experiences and the influence of the society they grew up in. This study found that the participants accepted the role of the biological father as central in their lives and its absence resulted in psychological and economical difficulties. To cope with such difficulties, the support from other family members or other father figures was found to be significant in participants lives. Also, this study found that father absence motivates the participants to succeed to better their lives and majority of the participants regarded their grandmothers as father figures.

- Description: The purpose of this research is to explore access and control of biodiversity in the context of biopiracy with specific reference to the case of pelargonium sidoides in the Raymond Mhlaba Local Municipality. The research is informed by the increased appropriation of local biodiversity and indigenous knowledge by industry as well as global debates on promoting sustainable resource utilisation and sustainable rural livelihoods. This study adopts a two-pronged conceptual approach mainly, Marx’s Ecology and the Sustainable Rural Livelihoods Framework (SRLF). The former provides useful insights into the processes and dynamics of power asymmetries between developed and developing countries, capital accumulation, inherent displacement and the predatory nature of capitalism. Whilst the latter addresses how livelihoods are fashioned in a holistic way. As a significant starting point the South African political economy is examined through the lens of the two economies debate. This research is primarily qualitative using in-depth interviews, observations and archival research as the primary data collection techniques. Preliminary site visits were conducted to negotiate access. Key informants of the study were representatives of the core groups (interested and affected stakeholders) involved in the case of pelargonium sidoides. Specifically, participants included representatives from the Imingcangathelo Community Development Trust and the Masakhane Community Property Association, local harvesters, local community members, monitoring and enforcement environmental officers, plant breeders (cultivators), scientists, local businessmen involved in natural resource trade, academics, legal representatives and non-governmental organisations. The Rhodes University research ethical guidelines were followed accordingly. The findings of the study suggest that trade in pelargonium sidoides is influenced by a complex and dynamic interplay between the state-industry-rural elite coalitions. Moreover, that this activity is largely centralised and exclusionary. This process is depicted in the unsustainable utilisation of pelargonium sidoides and other natural resources, the dismantling of local livelihoods, exploitation of harvesters and an incoherent environmental governance structure. At the core of this unequal system of exchange is industry, which effectively functions to generate profits whilst dispossessing peripheral communities such as the Masakhane community. The study therefore, argues that in order for local communities to access the trade there needs to be a shift in this system of unequal exchange. Not only regarding beneficiation, but in building community capacity and becoming involved as critical stakeholders in the governance of resources in the study area. The study found that there are competing narratives that inform the status and sustainability of pelargonium sidoides. Furthermore, given the current trajectory of the Masakhane community’s struggle for land, access to natural resources and exclusion from decision-making regarding pelargonium sidoides, the area will continue to be underdeveloped with concomitant poverty, inequality and comprised rural livelihoods.

It makes use of the distillation and fragmentation of these forms to explore themes such as the nature of violation, and works between genres to engage the tension between inner and outer realities, and the blurred lines between passivity and resistance. Moving fluidly between memoir and fiction and set in modern day South Africa, it draws inspiration from both my own experiences and the writing of others, especially Raul Zurita’s resistance poetry in Dreams for Kurosawa, Claudia Rankine’s subtle absurdity in Don’t Let Me Be Lonely, bizarro elements as seen in Athena Villaverde’s The Clockwork Girl and the use of physicality to explore the emotional world, as seen in Shelley Jackson’s The Melancholy of Anatomy: Stories.

- Description: Countries such as South Africa have attempted to leverage eHealth by digitising patients’ medical records with the ultimate goal of improving the delivery of healthcare. This involves the use of the Electronic Health Record (EHR) which is a longitudinal electronic record of a patient’s information. The EHR is comprised of all of the encounters that have been made at different health facilities. In the national context, the EHR is also known as a national EHR which enables the sharing of patient information between points of care. Despite this, the realisation of a national EHR system puts patients' EHRs at risk. This is because patients’ information, which was once only available at local health facilities in the form of paper-based records, can be accessed anywhere within the country as a national EHR. This results in security and privacy issues since patients’ EHRs are shared with an increasing number of parties who are geographically distributed. This study proposes an access control model that will address the security and privacy issues by providing the right level of secure access to authorised clinicians. The proposed model is based on a combination of Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC). The study found that RBAC is the most common access control model that is used within the healthcare domain where users’ job functions are based on roles. While RBAC is not able to handle dynamic events such as emergencies, the proposed model’s use of ABAC addresses this limitation. The development of the proposed model followed the design science research paradigm and was informed by the results of the content analysis plus an expert review. The content analysis sample was retrieved by conducting a systematic literature review and the analysis of this sample resulted in 6743 tags. The proposed model was evaluated using an evaluation framework via an expert review.

- Description: The expansion of technological developments in all areas of society has seen governments taking advantage of new technologies to enhance public service delivery, disseminate information and promote participation by the public in government decision-making. This phenomenon is known as electronic government, or e-Government. However despite the socio-economic benefits inherent in the implementation of e-Government systems, an overwhelming number of government projects – particularly in developing countries – struggle to successfully implement e-Government systems. e-Government project failure is more pronounced in developing countries, with more than half of these projects either partially or completely failing. The failure of e-Government projects undermines government investments, as well as the potential socio-economic benefits that could be realised by the citizens. Arguably, while the failure or success of an e-Government project is attributed to a myriad of factors, low user adoption is one of the key factors that contribute to e-Government project failure. Therefore this thesis seeks to investigate the phenomenon of low e-Government user adoption and determine whether the use of an Agile system development approach can positively influence e-Government user satisfaction as well as buy-in and adoption. A Mixed-Methods, multi-case study approach was used through the perspective of Post-Positivism. The researcher examined four (4) South African e-Government projects – using an online questionnaire and in-depth interviews with members of the system development team – to determine whether the use of an Agile approach has merit in enhancing e-Government user adoption. The use of a Mixed-Methods approach allowed for data triangulation so as to verify the findings; while the use of multiple case studies enabled for cross-case analysis. The findings indicate that the use of Agile practices, as listed in the proposed Agile-informed User Engagement Guidelines, can ensure that the e-Government system developed meets user needs; and, that users are satisfied with, and make use of the e-Government system. However since most large e-Government projects make use of a traditional Waterfall development approach, it is recommended that the Agile practices (proposed guidelines) be incorporated into the structured Waterfall approach – to create a hybrid, or blended system development approach. In conclusion, the use of the proposed Agile-informed User Engagement Guidelines can enhance e-Government user adoption; and, subsequently, contribute towards nurturing the success of e-Government projects.

- Description: Workplace fatalities and injuries are a concern around the world, with over 2 million deaths because of workplace related activities. This makes safety culture in the workplace crucial to the sustainability of individuals, businesses and the society in general. Safety culture includes everything in the workplace, and is understood as common sense awareness and practice relating to safety. Central to developing a safety culture in an organization, is a good understanding of what safety problems existed in the past; what safety problems exist in the present, and what caused them, as well as what could be done to deal with those causes. The goal of this thesis, therefore, was to understand what barriers potentially exist for Eskom employees in Makhanda (Grahamstown) to understanding and adopting the company’s safety policies and measures. A secondary aim was to explore different strategies for addressing these barriers. In order to get to the goal, it was important to; first, understand which aspects of Eskom’s health and safety standards do employees have difficulty adopting. Second, it was important to investigate the specific barriers to employees’ non-adoption of health and safety standards, by understanding their perceptions of safety issues in the workplace. Third, based on the findings, the study aimed to propose recommendations for improving the adoption of safety policies and measures by employees of Eskom. The key findings of the study include the fact that car accidents are the company’s and employees major concern, but the employees also have many other concerns that they see as needing the company’s attention (e.g. dealing with attacks on employees by customers; focusing on incentives rather than harsh enforcement for violators of safety policies). However, it is also clear that most employees do see safety as their responsibility as well. The two key areas of recommendations are, first, that leadership of Eskom adopt alternative leadership styles that focus more on ethical leadership, rather than transactional leadership that focus on profit margins more than it does on people. Second, it is recommended that Eskom provide incentives for compliance with safety policies; more training and education about safety; encouragement for Eskom to not put so much pressure on employees, who can lead fatigue; rather they should employ more people to do the jobs that the high pressure. To conclude, this research argues that neither do employees not employers think death and injuries are good for anybody. This is why this researcher is hopeful that this will get better, not worse, in terms of having a firm safety culture at Eskom as a workplace environment.

- Description: The relationship between visualisation processes and using manipulatives in the teaching and learning of mathematics is apparent and yet not so vocal in the literature. This could be because of the common mistaken understanding that because manipulatives are visual in nature, then visualisation processes should be obvious. Literature warns that just because something is visual therefore it is transparent, is incorrect. This study argues that the effective use of manipulatives in the teaching of mathematics helps learners to effectively understand mathematical concepts. Research on the teaching and learning of mathematics suggests that physical manipulation experiences, especially of concrete materials concerning shapes, is an important process in learning at all ages. One such teaching tool, the Geoboard, a physical manipulative that employs visualisation processes when correctly used, is explored in this study. The aim of this interpretive case study was to investigate and analyse the use of Geoboards as a visualisation tool in the teaching of the properties of quadrilaterals. The study focused on visualisation processes and the use of Geoboards through a teaching framework that was informed by the Van Hiele phases of teaching geometry. The study was conducted in the Opuwo circuit of the Kunene region, Namibia, and it involved three selected Grade 7 mathematics teachers, each from a different primary school. It was underpinned by a constructivist theory using the Van Hiele phases of teaching geometry and framed within visualisation processes. The study employed the use of qualitative data collection techniques such as observations and interviews. The analysis of the findings of this study revealed that Geoboards were very useful in demonstrating the visual representations of the properties of quadrilaterals in a cheap and yet novel way in the selected teachers’ classes. Moreover, the use of Geoboards by the selected teachers effectively fostered visualisation processes such as concrete pictorial imagery, dynamic imagery, perceptual apprehension, sequential apprehension, discursive apprehension and operative apprehension. It was also revealed that Geoboards enabled the selected teachers to structure and teach their lessons in a well-planned manner according to the Van Hiele phases, although it was difficult for them to adhere strictly to the hierarchy of the phases.

- Description: The increase in obesity is a global crisis that is prevalent in both the developed and developing economies, including South Africa. It endangers the health and threatens the life of many people. Sugar-sweetened beverages have become the key target in the fight against obesity, in preference to other foodstuffs that contain added sugar, because of the poor nutritional value they contain and harm they cause if consumed excessively. The Minister of Finance announced in the 2016 Budget Speech, that a proposed tax on sugar-sweetened beverages would be introduced in South Africa and would be implemented in April 2017, but the anticipated date is now 1 April 2018. The thesis examined the possible success of this proposed tax in South Africa, using as a benchmark the process followed prior to implementing the tax and the experience of selected foreign countries that have implemented the tax, one country subsequently abolishing it, and another country considering implementing it. Additionally, the research analysed the success of the existing excise taxes levied on tobacco and alcohol in South Africa, in attempting to predict the possible success of the proposed tax. The success of the proposed tax is, however, threatened by the emergence of illegal markets that offer the targeted products inexpensively, particularly if similar restrictions and laws do not exist in bordering countries. The research was carried out by means of the analysis of journal articles, information from the selected countries’ revenue authorities’ websites, National Treasury publications, commentaries by experts and publications by professional organisations and firms. Overall, the proposed tax has been successful in curbing obesity and high sugar intake in other countries. Similarly, the excise taxes on tobacco and alcohol have been successful in reducing the consumption of targeted products in South Africa. These successes have been realized through a collaborated effort and employing a multi-faceted approach, including advertising restrictions. Nevertheless, the proposed tax is popularly criticised for its regressive nature and the potential job losses that are associated with it.

- Description: There is ample evidence in the literature that gestures are important hand and bodily actions that play vital roles during interactions between learners and teachers in the mathematics classroom. These gestures enable both the teacher and the learner to visualise mathematical concepts and ideas. The aim of this Namibian interpretive case study, located in enactivist theory, was to analyse the types of gestures that three selected teachers at the junior primary phase (Grades 0–3) used in their teaching of mathematics. The study also interrogated the roles that these gestures played in the teaching process of the three teachers. As I intended to analyse the types of gestures the selected teachers used and understand their views and perceptions of the roles and functions their gestures played as visualisation tools in the teaching of mathematics, I observed ten lessons of each teacher and video recorded them. I then interviewed them (one-on-one stimulus-recall interviews) and interpreted the gestures they used and utterances they made about using these gestures. The types of gestures that the participating teachers used are classified according to McNeill‘s (1992) framework, namely pointing (deictic) gestures, iconic (illustrators) gestures, metaphoric gestures, beat (motor) gestures and symbolic (emblems) gestures. The study found that the participating teachers incorporated a variety of gestures into their lessons and used them strategically. According to the teachers, gestures made the lessons interesting and encouraged active participation of the learners in the lessons. The teachers also revealed that gestures assist in explaining mathematical concepts and thus affected the learners‘ understanding positively. This study strongly suggests that the usefulness and efficacy of employing gestures as visualisation tools in mathematics education should be strategically harnessed.

- Description: The Domain Name System (DNS) protocol is a fundamental part of Internet activities that can be abused by cybercriminals to conduct malicious activities. Previous research has shown that cybercriminals use different methods, including the DNS protocol, to distribute malicious content, remain hidden and avoid detection from various technologies that are put in place to detect anomalies. This allows botnets and certain malware families to establish covert communication channels that can be used to send or receive data and also distribute malicious payloads using the DNS queries and responses. Cybercriminals use the DNS to breach highly protected networks, distribute malicious content, and exfiltrate sensitive information without being detected by security controls put in place by embedding certain strings in DNS packets. This research undertaking broadens this research field and fills in the existing research gap by extending the analysis of DNS being used as a payload distribution channel to detection of domains that are used to distribute different malicious payloads. This research undertaking analysed the use of the DNS in detecting domains and channels that are used for distributing malicious payloads. Passive DNS data which replicate DNS queries on name servers to detect anomalies in DNS queries was evaluated and analysed in order to detect malicious payloads. The research characterises the malicious payload distribution channels by analysing passive DNS traffic and modelling the DNS query and response patterns. The research found that it is possible to detect malicious payload distribution channels through the analysis of DNS TXT resource records.

- Description: There are issues that always arise when it comes to gender identities and gender expressions. These issues are a result of the gender binary that corners people into being either feminine or masculine. Our societies are shaped in ways that supports this gender binary. If you are born a female, you are expected to be feminine and if you are born a male you are expected to act in a masculine way. When a person whose gender identity does not correspond with his or her assigned sex at birth, their behaviour is problematized and sometimes even criminalized and they are considered as deviant individuals by many societies. Consequently, most people who do not conform to gender societal norms are more exposed to violence, stigmatization, discrimination, marginalization, and victimization. People have difficulty understanding that there is ‘gender variance’, in other words, that there are more than just two genders. It is apparent that, even though societies enforce the gender binary, there are individuals who wish to express their genders in different ways, thus there are people who identify as transgender. The main focus of this dissertation is on the gender identities of transgendered people. Transgender people are people whose gender identity and or gender expression is distinct from the sex to which they were assigned at birth. The transgender group is a minority group (including in African countries) and one can argue that it is either misrepresented, misunderstood, hardly visible and ignored. This is evident when one looks at the lack of research on transgender populations in Africa. The main purpose of this research is to investigate the understandings that people have about transgender people on a South African university campus. In this dissertation the intent is to explore what it means to be transgender, the Rhodes University students’ understandings of transgendered people, the issues of gender identities and gender expressions and the challenges that transgender people face. The research question that this dissertation seeks to find an answer to is “Do Rhodes University students understand the notion of transgender and how do they react towards transgendered people on campus?”

- Description: Most regions of the developing world are experiencing large-scale urbanisation, with urban population growth outstripping rural growth. This is most marked in small and medium-sized towns as opposed to megacities. Urbanisation is associated with numerous changes in social, economic and ecological states and dynamics. A key one, of interest in this study, is the sustainability and liveability of the growing towns and cities. The retention, provision and maintenance of multifunctional urban green infrastructure are a core strategy in this regard. This study therefore sought to assess the amount, distribution and use of urban green spaces within South Africa using small towns of the Eastern Cape. The primary research included sixteen aerial images of which eight were historical aerial photographs and another eight were the latest aerial images of the selected study towns. Historical and latest aerial images were digitised to classify the types and calculate the amount of urban green space. GIS mapping, interviews and focus group discussions were conducted with urban residents to understand how these green spaces are used. The analytical tools in this study derived from social science included household surveys of 180 randomly selected respondents in small towns. Fifteen types of green spaces were identified in the sample towns. The study further revealed that green spaces are not distributed equally in different suburbs of small towns, generally being less green spaces, especially formal parks and recreation areas, in poorer areas. The results indicated a decline of green spaces with urbanisation, and most marked in fast growing towns. The results suggested that urban residents frequently visited urban green spaces, with most respondents favouring the use of green spaces for social and cultural benefits. How use of different spaces was strongly gender related, with males favouring less developed green space types (such as commonages and woodlands) and females for formal areas such domestic and institutional gardens and churchyards. Respondents also identified various challenges associated with using and accessing urban green spaces, with pollution, crime and lack of maintenance in particular. The study shows the importance of GIS as a mapping tool that can be used to provide information for ecological planning in rapidly changing urban environment. The research process generated several lessons that need to be taken into consideration when designing urban landscapes, most importantly relating to the diversity, quantity, quality and maintenance of urban green spaces.

- Description: The study explored how professional learning communities can contribute to the development of teachers’ capabilities and achievement of valued functionings related to teaching environmental content knowledge in the Life and Living strand in Grade 8 Natural Sciences. This is in the context of the Curriculum Assessment and Policy Statement (CAPS), which is a content-referenced curriculum that requires active and critical approaches to learning, and to environment and sustainability content. This study is designed as a qualitative case study of a professional support forum (PSF) in the Mahikeng sub-district, in North West. The study made use of questionnaires, observations, interviews and document analysis as data generation methods. The Capability Approach was used as a theoretical and conceptual framework to explore teachers’ valued functionings, as well as the conversion factors related to those functionings. A functioning is defined as what a person values to be or do, hence the term valued beings and doings has been used interchangeably with the term valued functionings throughout the study. The analysis of data was done in three phases. Phase one analysis was inductive with the data from questionnaires, classroom observations, document analysis (work schedules and lesson plans or preparation books). The purpose of this phase was to answer the first research sub-question of how teachers teach environmental content. Phase two was a deductive analysis, and the purpose was to present teachers’ valued beings and doings in teaching environmental content, and in belonging to the PSF. The last phase of analysis was abductive, and it employed the theoretical framework of Sen’s Capability Approach to get a deeper understanding of factors that either enabled or constrained teachers’ valued beings and doings associated with their capabilities. The study found that teachers have gaps in their environmental content knowledge in the Life and Living strand grade 8 Natural Sciences. This was mainly as a result of teachers not having relevant qualifications, and/or not having any professional development in teaching the environmental content knowledge. Secondly, teachers used traditional methods which were teacher-centred to teach environmental content knowledge. The gaps in the environmental content knowledge were constraints to how the teachers taught environmental content in their classrooms. Teachers’ valued beings and doings related to teaching environmental content were discussed under the three conversion factors of the capability approach: personal, social and environmental conversion factors. The study found that teachers’ qualifications, experiences, passion for environmental content topics, level of confidence, teaching and learning resources, learners’ interest and participation, support, classroom and schools’ environment were among conversion factors that either enabled or constrained teachers’ valued functionings in teaching environmental content Findings also revealed that teachers have different valued functionings related to belonging to the PSF: shared responsibilities, shared values and vision, collaboration, and discussion of subject content. The conversion factors related to these functionings were found to be learning space, time and duration of the PSF, activities in the PSF, teaching and learning resources, teaching experience, and facilitation. The study recommends that teachers’ professional development programmes should promote subject content discussions as well as group and individual learning. They should also create supportive conditions that will expand teachers’ capabilities in teaching environmental content knowldge. Lastly, the teachers’ professional development programmes should explicitly take into account teachers’ valued functionings and conversion factors that can enable teachers to develop their professional capabilities.

- Description: This research sets out to examine colourblind racism in contemporary South Africa, specifically, as expressed on social media networks. In South Africa, a nation lauded for its transition from Apartheid to liberal democracy, racism still continues to exist. In the new democracy, racism continues in old, familiar forms but it has been suggested that racism also assumes new and emergent forms such as ‘colourblind’ racism. This is evident in recent controversies involving local public figures and their expressions of ‘soft’, ‘colourblind’ racism on Facebook. It is the new platforms and modes of racism unique to democratic South Africa which this thesis attempts to explore. Specifically, this study is framed by ‘post-racialism’, a concept developed by scholars globally to capture the suggestion that in liberal democratic societies across the world, racism continues with racial inequality now underpinned by an ideology of colourblindness as opposed to overt policies of segregation. Colourblindness denies the relevance of race as a collective issue, proposing instead that other social factors such as class are more pertinent in considerations of social inequality. The purpose of colourblind narratives may be identified as the reduction of racism to mere individual action, denying systemic white privilege and historical responsibility for reparation as well as preventing racially subjugated groups from critically interrogating racial power and privilege (Goldberg, 2015: 28-30). Post-racial theorists agree that the projection of colourblind politics which claims to no longer ‘see race’ has instead served to secure the normalisation of white privilege and black subjugation (Bonilla-Silva et al, 2004: 559-560). The purported existence of colourblind /post-racial racism and its impact requires exploration in the context of South Africa today. In expanding on the definition of racism, we are able to see that racism is an adaptive system of power that is able to reproduce and reconceptualise itself to changes within society. As modalities of racism have evolved, so have the platforms for its propagation. This research offers social media as a site of exploration for post-racial narratives. The case studies of Penny Sparrow, Helen Zille and Mabel Jansen are presented in this study as exemplars of post-racial liberalism, denial and exclusion. This research calls for the expansion of racial understanding so as to contest racial power structures as a continuing systemic issue in contemporary South Africa.

The case studies of Penny Sparrow, Helen Zille and Mabel Jansen are presented in this study as exemplars of post-racial liberalism, denial and exclusion. This research calls for the expansion of racial understanding so as to contest racial power structures as a continuing systemic issue in contemporary South Africa.

- Description: The present study specifically focussed on Faith healing as an indigenous healing system and its influence on the diagnosis and treatment of mental illnesses in the Eastern Cape province of South Africa. The study aimed to provide a descriptive overview of Faith healers’ perspectives on the diagnosis and treatment of mental illnesses in the Eastern Cape, as well as to compare conclusions reached with other categories of indigenous healers. The inter-category comparisons on a broader level allowed for a further comparative discourse with the mainstream western medical psychiatric view of mental illness. Therefore, the scope of this study does not include in-depth analyses of findings, but rather the generation of themes for comparative discussions. While there exists vast literature on the diagnostic and treatment perspectives of the other two categories of indigenous healing systems (traditional healers and herbalists), a limited number of studies have been focussed on Faith healing as an indigenous mode of healing. The present study attempted to address this gap in the literature in an effort to promote future collaborative work across all viewpoints, in the management of mental illnesses. This study, grounded in qualitative research, utilized thematic analysis as its theoretical framework. Non probability judgmental sampling was used to secure self-identifying Faith healers, where conclusions from them were drawn from data collected, using in depth semi-structured interviews and observation. The main findings of the study indicated that Faith healers’ perspectives on the diagnosis and treatment of mental illnesses are based mainly on indigenous cultural theories. Furthermore, that collaboration with other viewpoints is hampered by animosity, feelings of distrust and the fear of appearing inferior.

- Description: South Africa is facing a challenge of poverty, unemployment and low growth. Government has identified the small and medium-sized business (SME) sector as one of the ways through which to combat these challenges. Government has also set up programmes and agencies to support SMEs in their search for funding and other kinds of support. South Africa, however, has one of the highest rates of SME failures in the world, with the majority not surviving beyond three years. Alternative interventions are therefore required to support South Africa’s SMEs to become sustainable companies beyond three years and to contribute positively to economic growth, poverty alleviation and job creation. This paper explores one kind of intervention that has been used internationally and that is increasingly being adopted in South Africa. Accelerator programmes, aimed at supporting start-ups to get to the next level of their development, have been growing in numbers around the world, trying to replicate the success of the original accelerator programme – the Y Combinator – which was responsible for the success of household names such as Airbnb and Dropbox. Accelerator programmes help start-up companies define and build their initial products, identify promising customer segments, and secure resources, including capital and employees. By making these necessary resources available to start-ups, it may be possible to ensure that fewer start-ups fail and more SMEs remain sustainable into the future. Several accelerator programmes have been founded in South Africa, all with a similar aim: to accelerate the development of start-ups that have the potential to grow exponentially given access to the right resources. This paper examines how South African accelerator programmes work in terms of the key resources made available to the start-ups that participate in their programmes. An increasing number of academic papers have been written on accelerator programmes internationally, but little information is available for the South African context. This research study investigated the phenomenon of accelerator programmes in South Africa through the lens of Resource-based Theory. The theory posits that, in order to gain a sustained competitive advantage, companies need to utilise their resources (including physical, human and organisational) in a manner that is effective and efficient, both internally and externally. The research answers the following questions: How do accelerator programmes work in South Africa? What value (in terms of resources offered) do they claim to bring to start-ups that go through their accelerator programmes? An exploratory case study method was selected to understand the phenomenon of accelerator programmes in South Africa. Purposeful sampling was used in the selection of accelerator programmes, as it allows for the selection of information-rich cases. The research findings indicate that accelerator programmes in South Africa follow the structure of providing start-ups, over a period between three months and one year, with resources that will assist them to be successful into the future. The investigation finds that human and financial resources are some of the most valuable resources that accelerator programmes provide to start-ups to help progress these start-ups to their next level of development. The most important resource is mentorship from knowledgeable industry players who are themselves entrepreneurs. Access to networks to gain access to the market, as well as funding, is also made available by accelerator programmes. This investigation provides a glimpse of the accelerator programme phenomenon in South Africa and highlights the important role that mentorship from experienced entrepreneurs, and access to markets and funding, play in the development of start-ups.

An Integrated Management System to reduce False Codling Moth, Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) infested citrus fruit from being packed for export

- Description: False codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is indigenous to southern Africa and is an important pest of citrus in this region. As a result of its endemism to sub-Saharan Africa, several countries to which South Africa exports citrus, regulate it as a phytosanitary pest. Consequently, it is necessary to ship fruit to these markets under cold-disinfestation protocols. This has been possible, as until recently, all of these markets could be considered relatively small niche markets. The South African citrus industry exports approximately 130 million cartons of fruit (15 kg equivalent) annually. During the 2017 season, a total of 48 million cartons were exported to the European Union (EU), which is the equivalent of 41% of South Africa’s total export volume, thus making the EU South Africa’s most important export market. In 2013 the European and Mediterranean Plant Protection Organisation (EPPO) conducted a pest risk analysis (PRA) on FCM, leading to the EU declaring it an officially regulated pest for this region, effective of 1 January 2018. Citrus is regarded as a preferred non-native host of FCM and South African citrus was identified as a primary focus due to large volumes being exported to Europe. Shipping under cold disinfestation is not possible with such large volumes of fruit. Additionally, several cultivars would suffer high levels of chilling injury under such conditions. In this study, an Integrated Management System was tested with pre- and postharvest controls to test the hypothesis that pre-harvest interventions resulted in lower post-harvest infection. Thirty orchards ranging from soft citrus cultivars such as Nule and Nova Mandarins, to Navel orange cultivars such as Newhall, Palmer and Late Navel and ending with Valencia cultivars such as Midknight and Delta, were identified for this study. This system relies on pre-harvest inspections such as FCM trap counts and fruit infestation on data trees in every orchard, with associated thresholds for action or continued compliance. Inspections were conducted on a weekly basis. There was a significant relationship between the moth catches and FCM infestation for the full monitoring period, using a two-week lag period for infestation. Inspections of harvested fruit were conducted at the packhouse to determine FCM infestation. This included inspection of the fruit on delivery to the packhouse, on the packing line, and a final fruit sample taken from the packed product and inspected for FCM. The highest levels of infestation were recorded on the Navel cultivars, thus confirming that Navels cultivars are a preferred host for FCM. Significant positive relationships were recorded between FCM infestation during the last 4 weeks before harvest and the level of infestation in the fruit delivered to the packhouse and between the fruit delivered to the packhouse and in the fruit packed in a carton for export. There was a substantial reduction in infestation between the fruit delivered to the packhouse and the fruit packed in a carton for export, with certain orchards recording as much as a 93% reduction in the fruit packed in a carton, which indicated that the packhouse could effectively identify and remove FCM infested fruit. The outcome of the study is that a holistic management approach minimizes the risk of FCM in citrus fruit destined for export and therefore mitigate the risk associated with FCM.

- Description: In South Africa, the current Maternal Mortality Ratio (MMR) is 135 per 100,000 live births, with a long way to go before it can achieve the Sustainable Development Goal (SDG) global target of under 70 per 100,000 live births by 2030. This research project focuses on the narratives of pregnant womxn in the Eastern Cape Province, using an intracategorical intersectional framework and Macleod’s ‘supportability’ model as a base. The study aims to locate womxn’s pregnancies within the interweaving biological, psychological, social, economic, cultural and political contexts within which they occur, while focusing specifically on the aspect of ‘supportability’. Through purposive sampling and snowballing methods, the research team recruited participants who were 18 years and older, in or past the second trimester of their pregnancy, and able to access antenatal care. Research data were produced using photo-elicitation techniques on 92 photographs and narratives from 32 interviews. An intersectional thematic analysis was used to generate themes, which highlighted different aspects that enabled or hindered pregnancy ‘supportability’. In accordance with prior research, it was revealed that womxn found emotional and tangible support the most beneficial. Findings from this study reveal the interconnectedness between a womxn’s personal (emotional, physical and cognitive) experiences of pregnancy, the micro-interactions of support (un)available from partners, family, friends, healthcare workers, workplaces and community members, and the macrostructures of socioeconomic policies, religiosity, cultural practices and healthcare systems. For example, gendered perceptions (a macro-structure) influence the instrumental support provided by partners (a micro-interaction), which impacts the womxn’s well-being (personal). Certain themes that emerged from the different narratives were: the importance of making available pregnancy-related information to the womxn; a desire for non-judgement and acceptance of their pregnancies within their community; and the need for adequate communication in microinteractions. The findings of this research also indicate that, despite the financial tensions inherent in each womxn’s life, the participants were driven by overarching hopes for their child’s future.
