- Description: Mass spectrometry (MS) is a technique that measures the fragmentation of molecules, dependent on the molecule’s chemical composition and structure, by first introducing a charge on the molecules. The instrument records the mass to charge ratio, but the energy from the ionization process causes the molecule to fragment. The resultant mass spectrum is highly indicative of not only the molecule analyzed, but also its chemical composition. MS is used in research and industry for both routine and research purposes. One such way to ionize molecules for MS is by bombarding the molecule with electrons which is the basis of electron impact mass spectrometry (EIMS). Although EIMS is widely used, prediction of electron impact mass spectra from first principles is a challenging problem due to a need to accurately determine the probability of different fragmentation pathways of a molecule. Ab initio molecular dynamics based methods are able to explore in an automatic fashion the energetically available fragmentation paths thus give reaction mechanisms in an unbiased way. The mass spectra of five molecules have been explored in work-flows leading to the prediction of mass spectra. These molecules include three natural products alpha-hispanolol, PFB oxime derivative and boronolide (for which experimental mass spectra were not available) and two compounds from the NIST database (for which experimental mass spectra were available). For each of these systems many random conformations were generated using the RDKit library. To all conformations random velocities were applied to each atom. Ab initio molecular dynamics was performed on each conformer, using these initial random velocities using CP2K software, at DFTB+ level at a variety of highly raised temperatures (to accelerate the formation of fragments) Fragmentation was monitored by iterating through all bonds, and identifying bond breakages during dynamics. Graph theoretical packages were used then to track distinct fragments generated. For each of these fragments, charges were determined from Mulliken analysis for all atoms on the fragment from the QM calculations and sum of atomic spin densities per fragment was also plotted. The fragment with the greatest charge (corresponding to the formation of a cation fragment) was taken for plotting on the mass spectrum. Finally, from the mass of the fragment and its elemental composition, the isotopic distribution for the fragment was determined, and this distribution was included by addition in to the mass spectrum. For all trajectories, the sum of all isotopic distributions determined the final mass spectrum.

- Description: This study seeks to understand how Rhodes University first-year male students adjusted and re-adjusted their masculinities and sexualities in light of the Consent Talk programme offered by the university, the aim of which is to liberate masculinities and femininities from patriarchal and dominant discourses. In the past 26 years, South Africa has seen an increase in academic research establishing causal links between boys, men, masculinities and a number of social ills such as the HIV/AIDs epidemic, violence against women, substance abuse, homophobia, gender-based violence and a lower pass rate amongst boys. This in turn inspired an increase in interventions seeking to involve boys and men in order to identify and address their role in combating gender based violence. These various forms of social deviances that have been linked to masculinity have indicated that young men's masculinity is in crisis and as a result needs great attention in order to address the social issues linked to them. Institutions of higher learning have proven to be microcosms of the larger society. Universities have become highly sexualised spaces; coercive sexual practices in heterosexual relationships are a norm, young women don't feel safe and have lost confidence in universities addressing their concerns. With the emergence of the #RUreferencelist in 2016, the spotlight fell on Rhodes University; young women challenged the rape culture and sexual assaults on campus. In 2016, staff members who are well-informed and educated on issues of gender, sexuality and rape initiated discussions with students in their residences; these discussions were later to be called the Consent Talks. This research makes use of Pierre Bourdieu’s critical theory in understanding how young men negotiate their masculinity within the field of higher education, at Rhodes University. Bourdieu’s three main concepts, field, habitus and capital are used to describe how young men negotiate their masculinity and how the field of gender intersects with the field of higher education. A qualitative paradigm has been employed. The study has collected data through the use of in-depth interviews to get a richer insight into the participants’ perspectives. There were 15 interviews conducted in total for this study, 14 were with first year male students, and one with a senior official of the University. The data was analysed through a qualitative thematic analysis. The findings of the research reveal that some of the participants were exposed to patriarchal and dominant forms of masculinity when growing up. However, most of the participants revealed they were also exposed to alternative masculinities. These were either taught or learnt at home, from family members, circumcision school, church or peers in society. Both the dominant and alternative masculinities were revealed in the discourses of what it means to be a man and in how the young men performed their masculinities. Furthermore, one of the major themes that emerged was that most of the young men in the study were raised by single mothers with mothers playing a significant role in encouraging healthy masculinities. The findings went on to reveal that families (mothers, fathers, older siblings and culture) play a role in socialising and shaping healthy masculinities. The acceptance or rejection of either dominant or alternative masculinities was influenced by an exposure to an environment that either encouraged or shunned either dominant or alternative masculinities. The findings further unveils that different societies are strongly identified with their own definitions of what it means to be a man and are not open to other definitions of masculinity. Moreover, most of the participants accepted the content of what was taught in the Consent Talks; however sought healthy participation, interaction and inclusion of female students. Lastly, the study has also revealed that knowledge of the consequences of breaking (the law) university’s policy does affect some change of behaviour in potential perpetrators.

- Description: In South Africa, Psychology has had a chequered past mainly due to its role in the justification of apartheid policies. Due to apartheid's socio-economic injustices, confidence in the applicability of psychological knowledge to South Africa's social problems was insufficient. Psychologists attempted to raise consciousness of the social relevance of psychology by contributing relevant knowledge and being reactive to social inequalities and related psychosocial issues affecting South Africa. This study aimed to conduct a content analysis of trends in research produced by Psychology Masters' students in the fields of Clinical, Counselling and Research psychology over a period of 5 years (2008-2012). The corpus of data was then compared with the key issues raised in the United Nations Development Programme's South Africa human development report (2003), along with a focus on articles published by Macleod (2004) and Macleod and Howell (2013). It emerged that Empirical Qualitative studies, based on post-modern frameworks, as well as HIV/AIDS, Knowledge Production, Assessment and Measurement and Programme development and evaluation, dominated psychological research. Participants were mainly urban, middle class adults living in the 3 wealthiest provinces. University students were the most popular participant group. While it is encouraging that students were attempting to engage with psychosocial issues, the limited number of key social issues addressed, the under-representation of certain sectors of the South African population, as well as the impact of socioeconomic status on well-being requires greater attention at Masters' level to ensure Psychology's psychosocial relevance.

Reporting drought: framing an anthropogenic natural disaster in the South African mainstream publication, City Press, over three years (2015-2018)

- Description: This study interrogates how the ongoing anthropogenic drought, declared a disaster in five South African provinces in 2015, has been represented by mainstream news media. The news media enables public participation which is vital to climate action and the regulation of harmful neoliberal practices that fuel climate change and are thus necessary to provide information about climate change and to support political interventions. Despite the gravity of the drought crisis, there is a severe lack of public opinion about it and the complex weather patterns to which it is attributed. This study thus investigates how the drought has been framed by mainstream news media in South Africa, confining itself to a single title, the City Press. To analyse representations of drought in the City Press, this study adopts a Foucauldian approach to discourse which considers representations as meaning constructed through language. The knowledge perpetuated in news texts is thus frequently perceived as the ‘truth’ about the drought. This knowledge is imbued with power as those in positions of authority determine what is articulated as truth. Through various institutional practices, journalists limit what is said about the drought, framing it in particular ways and privileging particular voices. What the public learns about the drought (and in turn, climate change) is thus limited by the norms and routines of the journalistic regime and the corporate nature of ownership. Notably, the City Press operates within the neoliberal economic order to which climate change is attributed. This study is located within the Cultural Studies and Journalism Studies paradigms and is further informed by a qualitative methodology and two methods of textual analysis, that is, thematic analysis and Critical Discourse Analysis. The sampling process produced a database of 26 news texts published by the City Press between the years 2015 to 2018. Five texts were purposively selected for an in-depth analysis based on a broad thematic analysis as reasonably representative of the discourses that recur. Although the City Press positions itself as a critical purveyor of political information, only three themes recur in the texts. These themes position drought in relation to the agricultural economy and urban infrastructure; foreground the voices of corporate entities; while the climate science behind weather patterns is inadequately interpreted. Any discussion of climate change and alternatives to mainstream economic practices is almost entirely omitted.

- Description: The study investigates how journalists working for state media in Botswana experience reporting on development in rural communities. It is observed that many of these journalists are members of the rural communities they report on and therefore have personal knowledge of them. Furthermore, it describes how even though Botswana is often praised for its developmental achievements, the country continues to be characterized by social inequality. The study then articulates a theoretical framework designed to engage with the normative guidelines that inform journalistic practice within the Botswana media landscape. It draws, for this purpose, on normative theories of the press. It is concluded that the Botswana media landscape is representative of an authoritarian, polarised pluralised media system in which journalists work under strict control of the state. The empirical component of the study draws on this framework by conducting life history interviews of journalists working at the Botswana Daily News. It examines what such journalists know from personal experience about development from rural Botswana and how such knowledge impacts on their engagement with the processes of reporting for the paper. It is concluded that journalists working for this paper have a deep commitment to representing the interests of rural communities. However, they remain constrained in their ability to act on this commitment, in context of the guidelines for reporting that frame their institutional context.

Resisting the ‘Native Informant’ trope in examples of African Diaspora art and literature

- Description: This thesis draws attention to the existence of the ‘native informant’ trope in the African Diaspora. It argues that a strong emphasis towards studying diasporic groups in relation to their African origin revives, consequently, the colonial politics that underpin the continent as an unknown mythical place. In response to this issue, I introduce multidisciplinary case studies that highlight various artists and authors who resist and challenge the diasporic individual as the ‘native informant’. Their works reinterpret and redefine the relationship between African communities, their connection to the continent and their experiences of living abroad. Analysing the exhibitions Looking Both Ways, Africa Remix and Flow, I investigate their visual art discourses that interpret diasporic artists and their works as cultural embodiments of their African background. As a result, the three art shows marginalise other potential readings to view diasporic experiences. This thesis introduces three resistant themes that reconceive the diasporic person’s relationship to the African Diaspora based on language, spatial interaction and self-identification opposed to a geographic tie. The first theme (language) references Victor Ekpuk’s drawings and Isidore Okpewho’s novel Call Me By My Rightful Name to suggest a language based diasporic experience. The second theme (spatial interaction) looks at Emeka Ogboh’s sound installations and Teju Cole’s novel Open City. Both works examine a diasporic individual’s conflicted engagement with her place of origin. The third theme (self-identification) considers the individual-community relationship in Wura-Natasha Ogunji’s performance art and Chika Unigwe’s novel On Black Sisters’ Street. Each of these visual-literary pairs focus on various components that shape the African diasporic lifestyle. My research re-interprets the continent’s significance in the diaspora from a geographic construct to a socio-spiritual connection to a community. Firstly, it outlines the persistent issue of a colonial residue in Africa’s definition as a physical-cultural space, and secondly, it offers three alternative discourses to read diasporic identities outside a geographic framework. I argue that belonging is a social individual-collective effort rather than an anchor to a tangible environment.

- Description: Views on the importance of companies engaging in CSR initiatives have been debated widely and critics of the concept continue to argue both locally and globally. The objective of the study was to gain an in-depth understanding of the recipients’ perspectives on their involvement in CSR projects implemented in their community by a chosen mining company and the successes and challenges of the project. A qualitative research approach was used for the study. Using nonprobability purpose sampling, a total of 15 participants from Lusikisiki were selected for the study. The data obtained was analysed using inductive thematic analysis. The results of the study were discussed based on the three research questions of the study which focused on recipients’ perspectives on their involvement in the projects and their perceptions on the successes and challenges of the projects. The study found that the chosen mining company made a significant contribution towards developing the community. Furthermore, the study found that recipients’ involvement in the projects enabled them to realize their assets in one of the projects as a result of the shift in approach by the organisation as the project progressed (Needs Based Approach to ABCD Approach). In addition, the study found that the successes of the projects changed the recipients’ perceptions of themselves and enabled them to actively engage in transforming their lives. However, the projects did face many challenges and recipients posited that more still needs to be done by organisations to develop communities and ensure that projects remain sustainable long after their partnership has dissolved.

- Description: This study explores Rhodes University students’ experiences of living as students on National Student Financial Aid Scheme (NSFAS) funding. The Marxist theoretical framework critique of neoliberalism and welfare systems is used. The Marxist theory is the main theory that underpins the study. Eighteen participants were involved in an in-depth interview process. Out of 18 participants, one is a staff member at Rhodes University Financial Aid Office. The key findings of this research revealed the unfavorable circumstances of students on NSFAS at Rhodes University. Secondly, it was discovered that students shared similar sentiments as NSFAS and DHET: They recognize the major areas that need to be addressed by NSFAS. Thirdly, NSFAS had to some extent made a positive contribution to the higher education sector. Suggestions have been made on how my study may be improved to yield even better results.

- Description: J.J.R. Jolobe is regarded as one of the individuals who made a valuable contribution to the development of isiXhosa literature through his works, notably in his poetry (Ilitha, Umyezo; Jolobe 1936). His poetry ranges from abstract subjects to more philosophical matters. This study is aimed at decoding the manner in which he employs satire to conscientise African people of the then horrible situation that they were facing. With that said, poetry will not be the only work that this thesis analyses in the process of evaluating Jolobe’s satire; his essays will also be examined (Amavo; Jolobe 1940). Based on the writings of various authors specialising in the subject, satire has been deemed to be a style of literary writing, one which involves invective satire. For the researcher, that statement will be rebutted, as it will be argued that the mode of satire need not be wholly invective. Jolobe’s light-hearted satire not only showcases the amusing side of his writings, but also indicates the seriousness with which they were intended. Themes covered in Jolobe’s satire have inspired the researcher to evaluate these literary texts in relation to modern contexts, especially when it comes to the relationship between the lines of the author’s experience and the public. With that said, the social role of satire is something that one cannot deny. One could therefore say that there is an urgent need for African satirists to face the existing social and economic reality as authentically as possible. The voice of a satirist should also echo the voice of their society as a whole. Satirical study in post-colonial Africa, in South Africa in particular, is useful due to the idea that the works of the likes of Jolobe may diminish in significance due to neo-colonialism. In fact, this is the point which is considered in this study of Jolobe’s satire. This study also examines stages afforded to the development of satire in Africa, especially in the post-colonial era. The purpose is to identify the effects of satire that are related to socio-political as well as religious factors. These factors are often seen as those that play a vital role is one’s personal morals, and those that are meant to shape the whole community. Jolobe addresses imperialism and the class struggle, which speaks to the society’s loyalties regarding the mobilization toward realizing the dream of being independent. This speaks to the works analysed, revealing protests against oppression and exploitation by imperialists; such works show how inhumane people could be against those who they deem to be beneath their standards. Researchers like Mahlasela (1973), Sirayi (1985), Kwetana (2000) and Khumalo (2015) are amongst those who have made it a point to study Jolobe to ensure that these works are kept alive, along with their significance. Other prospective researchers can follow suite in researching the great Jolobe. In ensuring that the aims of this study come to light, the researcher will be using socialist realism as a way of seeing that the works of Jolobe are realistic in nature. With that said, there will be an exploration of allegoric satire. Satiric allegory will be evaluated with regard to the view that it represents a unique slant on satire, whereby it deems satire to be more than just a supportive method of literary criticism. This allows the researcher to hold the view that satire should not be a restrictive framework when dealing with African literature. Satire as a modern form of criticism can be viewed as having an element of humanism, which would result in the satirist doing all he can to make sure that what is satirized is not isolated from the struggle of the community. It is for the above-mentioned reasons that we see a big challenge in the future development of satiric discourse in African literature.

- Description: Natural rangelands provide a variety of ecosystem services including livestock production which occurs on land under freehold land tenure and on land under communal tenure. There is an ongoing debate around the extent to which land degradation is occurring on these rangelands under different land management and land tenure systems and what the main degradation drivers are. Over-grazing, rainfall and soil type are key drivers of rangeland dynamics and the resultant sediment yield in the river systems, however, over-grazing is an outcome of land management while rainfall and soil type are natural drivers. This study explores the relationship between rainfall and daily sediment flux as well as the seasonal trends of vegetation cover and the study is part of a greater research effort called the Tsitsa Project which is based in the Tsitsa River catchment (near Maclear, Eastern Cape, South Africa). The Tsitsa Project aims at developing and managing both land and water in a sustainable way by improving the land, water and lives of people living in the Tsitsa River catchment. The restoration efforts of the Tstisa Project will aid in extending the lifespan of both the proposed dams on the Tsitsa River. The Tsitsa River catchment is characterised by grasslands, steep topography, highly erodible soils with many large gullies present and a very high sediment yield in the Tsitsa River which allowed for the exploration of some of the system drivers of sediment yield in this catchment. The study involved two sub-catchments of the Upper Tsitsa River catchment of different land management strategies: one dominated by commercial livestock farms (Little Pot River catchment) and one dominated by communal rangelands (Gqukunqa River catchment). The aim of this study was to determine the seasonal trends of rainfall intensity, ground cover and sediment dynamics in the Little Pot River and Gqukunqa River catchments. The purpose of the findings was to improve management strategies in degraded areas and catchments. In order to achieve this aim a variety of field and desktop methods were used. Field methods involved measuring variables including: vegetation biomass, vegetation cover, soil surface hardness, biocrust cover and slope angle for a range of Normalized Difference Vegetation Index (NDVI) values from the Sentinel-2A sensor. The study assessed the system response of the field variables in both catchments over one rainfall season (2018-2019). Desktop methods included various NDVI analyses as well as analyses of trends and relationships between vegetation dynamics, rainfall and sediment. The relationship between erosive rainfall events, daily rainfall, antecedent rainfall and daily sediment flux was explored over the time period of January 2016 to January 2019 and October 2015 to January 2019 for the Little Pot River catchment and the Gqukunqa River catchment respectively. NDVI was explored as a proxy for vegetation cover to extrapolate across the catchments and monitoring period. NDVI was found to have a weak positive relationship with vegetation cover and biomass (R2 values ranged from 0,04 to 0,525). Mean monthly catchment NDVI values, biomass and vegetation cover increased throughout the wet season of 2018-2019 in both catchments. Mean monthly NDVI values increased from 0,26 to 0,55 in the Little Pot River catchment and from 0,29 to 0,53 in the Gqukunqa River catchment over the course of the 2018-2019 wet season. NDVI, biomass and vegetation cover was found to be higher on south-facing slopes than north-facing slopes in both catchments for the majority of the wet season. The Gqukunqa River has significantly higher daily sediment fluxes than the Little Pot River despite similar NDVI and rainfall intensities which is owed to the dispersive soils in the Gqukunqa River catchment. Soil surface hardness results were inconclusive due to rainfall before or during every field trip which changed the properties of the soil. The largest erosive rainfall, daily rainfall and daily sediment events occurred from January to March each wet season in both catchments. Rainfall intensity and sediment fluxes were found to have a weak relationship, however, there was a stronger relationship found between antecedent rainfall and sediment flux. The larger daily sediment fluxes in each catchment often did not result from an erosive rainfall event on the same day but rather from multiple days of rainfall which can result in saturated soils and runoff leading to surface and sub-surface erosion. The possibility of sub-surface erosion via chemical processes contributing to the larger sediment events was also explored to explain the stronger relationship between antecedent rainfall and daily sediment flux.

- Description: The onset of globalisation and simultaneous changes in financial technology and financial reforms dissipated hurdles once faced in financial transactions among stock markets. Hence, stock markets around the world became increasingly integrated because there was a free flow of cross border investments. Consequently, international diversification diminished thereby undermining the ability of investors to diversify investments across borders. For that reason, recent literature on portfolio diversification is urging investors to shift their focus to domestic portfolio diversification as an alternative. On that account, this study aims to examine the co-integration and dynamic causalities between South African equity market sectors in order to ascertain the sectoral diversification opportunities available to domestic investors over time. The study was examined over the different phases of the business cycle as well as the full sample, i.e. 2004 – 2018, with a view to shedding light on the inter-sectoral diversification opportunities of domestic investors over the South African business cycle. The phases of the business cycle applied are a| expansion and boom; b| recession and recovery phase and c| stagnation phase. The Johansen co-integration and Granger-causality tests were employed. The hypothesis of the study is that, if sectors are not cointegrated, then diversification benefits can be reaped by constructing a portfolio that combines stocks from the respective sectors. On the whole, the findings of this study show that there are both long-run and short-run diversification opportunities across the different phases of the South African business cycle as well as the full sample. However, there are lesser diversification opportunities in the recession and recovery phase over both the long-run and short-run. These results indicate that domestic sectoral portfolio diversification is least effective when it is needed the most (i.e. in a period of heightened volatility such as recession and recovery phase). This study will contribute to the existing literature in two ways; firstly, to investors who intend to diversify their portfolios domestically rather than internationally and, secondly, after reasonably thorough research it was evident that there is scant literature on domestic sectoral diversification in South Africa. As a result, the study attempts to address this gap. Additionally, the essence of the business cycle in this study is to make investors aware of potential diversification opportunities when positioning their portfolios for the next shift in the business cycle.

- Description: This research is aimed at software development companies and highlights the unique information security concerns in the context of a non-malicious software developer’s work environment; and furthermore explores an application driven solution which focuses specifically on providing developer environments with access control for source code repositories. In order to achieve that, five goals were defined as discussed in section 1.3. The application designed to provide the developer environment with access control to source code repositories was modelled on lessons taken from the principles of Network Access Control (NAC), Data Loss Prevention (DLP), and Google’s BeyondCorp (GBC) for zero-trust end-user computing. The intention of this research is to provide software developers with maximum access to source code without compromising Confidentiality, as per the Confidentiality, Integrity and Availability (CIA) triad. Employing data gleaned from examining the characteristics of DLP, NAC, and Beyond- Corp—proof-of-concept code was developed to regulate access to the developer’s environment and source code. The system required sufficient flexibility to support the diversity of software development environments. In order to achieve this, a modular design was selected. The system comprised a client side agent and a plug-in-ready server component. The client side agent mounts and dismounts encrypted volumes containing source code. Furthermore, it provides the server with information of the client that is demanded by plug-ins. The server side service provided encryption keys to facilitate the mounting of the volumes and, through plug-ins, asked questions of the client agent to determine whether access should be granted. The solution was then tested with integration and system testing. There were plans to have it used by development teams who were then to be surveyed as to their view on the proof of concept but this proved impossible. The conclusion provides a basis by which organisations that develop software can better balance the two corners of the CIA triad most often in conflict: Confidentiality in terms of their source code against the Availability of the same to developers.

- Description: False codling moth (FCM), Thaumatotibia leucotreta (Meyrick), is the most important pest for the cultivation of citrus in South Africa. False codling moth is indigenous to southern Africa and is a regulated pest of many international markets for phytosanitary concerns. Considerable research efforts have been invested in the past decades to develop semiochemcial technologies, such as monitoring with sex pheromones, attract-and-kill, mating disruption and the sterile insect technique. One of the potential obstacles identified with semiochemical control is the differences in the ratio of the compounds comprising the sex pheromone at different geographical locations, resulting in what is known as regional attraction. This has been identified in FCM populations from three different countries, however, regional attraction within South African FCM populations was unknown. Therefore, the study assessed the genetic integrity of five laboratory-reared FCM populations originating from geographically isolated populations in South Africa using the AFLP technique in order to assess regional attractiveness within the country. The results found isolated populations from Addo, Citrusdal, Marble Hall, Nelspruit and a fifth group found to be closely related to Addo and Citrusdal called the ‘Old’ colony. These five genetically isolated populations as well as a population from Xsit (Pty) Ltd, used for the sterile insect technique (SIT), were used in regional attractiveness trials. Males were significantly (P = <0.05) more attracted to females originating from the same population. No significant attraction could be determined from the sterile males, as the recapture rates in the trap were too low. Furthermore, regional attractiveness was assessed through choice/ no-choice mating compatibility trials. Significant sexual isolation (ISI) occurred between mating combinations Addo × Nelspruit (ISI = 0,13; t2 = 6.23; p = 0.02), Addo × Marble Hall (ISI = 0,11; t2 = 4.72; p = 0.04), Citrusdal × Nelspruit (ISI = 0,11; t2 = 4.95; p = 0.04), and Citrusdal × Marble Hall (ISI = 0,12; t2 = 4.31; p = 0.04). In these combinations, Addo and Citrusdal males were found to have outcompeted Nelspruit and Marble Hall males for more mating events. Significant sexual isolation was also recorded for Sterile × Marble Hall (ISI = 0.12; t2 = 4.98; p =0.01) and Sterile × Citrusdal (ISI = 0.13; t2 = 3.96; p = 0.01) populations. The male relative performance index was significant in both combinations, indicating that non-sterile laboratory males outcompeted the sterile males in these two combinations. When given no choice, evaluated as spermatophore transfer/ female/ 48h, all males (including sterile) were successful in transferring spermatophores to all FCM populations, with no significant differences. These results indicate that there may be incipient pre-isolation mechanisms affected by local natural selection, resulting in localised sexual attraction via differences in the sex pheromone ratios. These findings provide important information for semiochemical technologies and the implication of these results with regard to monitoring with sex pheromones, attract-and-kill, mating disruption and sterile insect technique are discussed.

- Description: False codling moth (FCM), Thaumatotibia leucotreta (Meyrick), is the most important pest for the cultivation of citrus in South Africa. False codling moth is indigenous to southern Africa and is a regulated pest of many international markets for phytosanitary concerns.

- Description: It is important for Higher Education Institutions to have marketing strategies that focus on understanding the customer needs in the 21st century. The rapid growth of the internet and the Web 2.0 have led individuals and organisations into applying social media as a branding and communication tool. Hence this study focused on comparing the influence of social media on four Eastern Cape universities in relation to social media metrics and visually demonstrated through the computer-generated human face, the Chernoff faces. Using diary and literature study, the study adopted a case study research design. The researcher sampled four universities using a purposeful sampling technique. Chernoff faces were used to enhance the ability of the reader to immediately understand significant occurrences based on social media metric indicators. To demonstrate multivariate data, the faces brought an original method of expressing complex data as opposed to traditional methods. The study found that Brand management and Resource-Based Theory (RBT) plays a pivotal role in social media marketing as this can lead to organisations having a competitive advantage. The study recommended that strategies to utilise social media as a resource should be put in place to lead to competitive advantage, as suggested by the Resource-based theory. The study concluded that various social media factors can influence the brand image of universities, positively (going to buy) and negatively (never going to buy). Both positive and negative purchase intent are found to be an influential indicator on the brand as they are affected by customer satisfaction.

- Description: Purpose: The goal of the research was to demonstrate how firms can use social media big data, to make strategic business decisions, through the lens of Resource Based Theory (RBT) and Dynamic Capability Theory (DCT), that could lead to a sustained competitive advantage. In and of its own, big data, does not constitute a competitive advantage. It may hold value for the firm, but lacks rarity, inimitability, and is not substitutable (Braganza, et al. 2017; Mata, Fuerst and Barney, 1995; Delmonte, 2003). It is in the analysis of this data, through RBT and DCT, that will turn the information into useful business intelligence (Amit and Schoemaker, 1993; Barney, 1991; 1995; Marr, 2015; Gupta and George, 2016; Kurtmollaiev, et al., 2018). Most importantly, firms must constantly reconfigure their resources in line with the dynamic business environment to ensure superior performance (Teece, Pisano and Shuen, 1997; Helfat, et al., 2007; Teece, 2014; 2018). Method: In this study, a qualitative approach was used to examine the RBT (Value, Rarity, Inimitability and Non-Substitutable - VRIN Framework) and DCT, to describe and understand the relevant theories and to build upon the quantitative results. While a quantitative approach was used to analyse the social media sentiment as depicted by Social Mention metrics. A novel technique, Chernoff Faces, was used to analyse and visualize the data (de Vos, Strydom, Fouche and Delport, 2011). Results and Findings: The research results show that, while the 10 firms in the study all have a presence on social media, it is on selective platforms. The content that is posted, is on very specific topics (Narayan, 2017; Cornejo, 2018). The Chernoff Faces indicate that the firms’ Social Mention metrics, over the 30 day period, was at low values. Since strength of social mention is depicted by the face line, the thin, long, generally sad looking faces implies that more than 70 percent of the firms’ social media strength over the study period, was weak. Conclusion: The literature indicates that the true value of big data and big data analytics can only be realised if firms make sound business decisions and act upon it swiftly.

South Africa’s mohair value chain: institutional framework, governance and the perceptions of management and labour

- Description: The primary objective of this research is to understand the ways in which the (working and living) conditions confronting employers and employees on mohair farms are the complex outcome of their position in the global mohair value chain, the nature of the labour process, and the ‘contours of voice’ (i.e., how and why employees voice). These three bodies of literature represent different levels of analysis: at the broadest level, the political economy of the mohair value chain is explained by drawing on the chain literature. This literature has been supplemented, at the level of the production process, by deploying the concepts of labour process theory (LPT), which focus on the control of work processes by management as well as workers’responses to this control. These responses were analysed by incorporating insights from the burgeoning research on employee voice (EV) in an effort to understand the practical ways in which workers on mohair farms articulate their needs and interests. The cross-collination of these three bodies of literature is, to my knowledge, a novel feature of this research on the mohair industry in South Africa, which, in turn, has itself been woefully under-researched. The research design consisted of a qualitative approach in which I used in-depth, semi-structured interviews and focus-group discussions as the primary sources of data collection. The secondary source of data was available publications and documents from the agriculture industry and mohair sector. A qualitative approach acknowledges and gives great insight and meaning into the research topic. Twenty participants were interviewed for my research: six from key organisations within the mohair industry, ten farmers, two mohair farm workers and two mohair shearers. The main findings of the research include the following: first, institutions in South Africa’s mohair industry not only determine (in part) the structure of the mohair value chain but also play a vital role in governing the chain. Each institution and actor plays a significant role in adding value to the mohair product that leads to economic upgrading. Second, understanding the actions of farmers (as employers) by drawing on LPT allows me to show how the systemic pressures of capitalist accumulation compel employers to continuously enhance their control over production – and, by extension, over workers – who, in turn, resist and/or accommodate to these impositions by management. Lastly, the research shows that employee voice at the farm level is complex and contested – not surprisingly, given South Africa’s troubled history – yet, it is increasingly exercised by farm workers and accepted by mohair farmers as a necessary and inescapable means of resolving issues that arise in the employment relationship at the workplace and remaining competitive in a global market.

Statutory mergers as contemplated in the Companies Act, 2008: the applicability of the corporate rules contained in section 44 of the Income Tax Act, 1962

- Description: The purpose of this research is to determine the extent to which a statutory merger in terms of the Companies Act, 2008, may be accommodated by the provisions of an amalgamation transaction in terms of section 44 of the Income Tax Act, 1962. The research method adopted is a legal interpretative research approach. South African company law underwent significant reform with the introduction of the Companies Act, 2008. One of the fundamental areas for reform was the need for a mechanism to appropriately accommodate a corporate merger, and thus, what is referred to as a statutory merger was introduced into South African company law. What is notable is that the statutory merger has been crafted to apply across a variety of circumstances that may arise in commerce, thus offering wide versatility. On the other hand, the tax relief afforded in terms of the corporate roll-over provisions in the Income Tax Act is designed to facilitate corporate transactions on a tax neutral basis, whilst balancing the concessions these measures introduce and the potential for tax avoidance. Consequently, the tax relief applicable to an amalgamation transaction will only apply within strictly prescribed parameters. The research shows an ongoing effort by National Treasury to amend the provisions of the amalgamation transaction to better accommodate a statutory merger, but highlights that there are nevertheless certain conflicting purposes (policy) for each piece of legislation. For these reasons, the focus and parameters of a statutory merger and amalgamation transaction do not align perfectly. The key areas of inconsistency identified in this research are threefold, namely (i) the creation of a new company as a consequence of a statutory merger is not accommodated in an amalgamation transaction; (ii) the process of compensating the shareholders of the amalgamated company in an amalgamation transaction is not clearly contemplated in the statutory merger provisions; and (iii) mergers between a company and its shareholder currently present numerous complexities from both a company law and taxation perspective. The research concludes that the flexibility afforded under the statutory merger is largely minimised for parties who wish to simultaneously enjoy the tax relief afforded under an amalgamation transaction.
