- Description: There has been a significant increase in the prevalence of Ransomware attacks in the preceding four years to date. This indicates that the battle has not yet been won defending against this class of malware. This research proposes that by identifying the similarities within the operational framework of Ransomware strains, a better overall understanding of their operation and function can be achieved. This, in turn, will aid in a quicker response to future attacks. With the average Ransomware attack taking two hours to be identified, it shows that there is not yet a clear understanding as to why these attacks are so successful. Research into Ransomware is limited by what is currently known on the topic. Due to the limitations of the research the decision was taken to only examined three samples of Ransomware from different families. This was decided due to the complexities and comprehensive nature of the research. The in depth nature of the research and the time constraints associated with it did not allow for proof of concept of this framework to be tested on more than three families, but the exploratory work was promising and should be further explored in future research. The aim of the research is to follow the Hybrid-Malware analysis framework which consists of both static and the dynamic analysis phases, in addition to the digital forensic examination of the infected system. This allows for signature-based findings, along with behavioural and forensic findings all in one. This information allows for a better understanding of how this malware is designed and how it infects and remains persistent on a system. The operating system which has been chosen is the Microsoft Window 7 operating system which is still utilised by a significant proportion of Windows users especially in the corporate environment. The experiment process was designed to enable the researcher the ability to collect information regarding the Ransomware and every aspect of its behaviour and communication on a target system. The results can be compared across the three strains to identify the commonalities. The initial hypothesis was that Ransomware variants are all much like an instant cake box consists of specific building blocks which remain the same with the flavouring of the cake mix being the unique feature.

- Description: Over the years there has been a substantial increase in the number of African stock markets. This has generated much interest from local and foreign investors, as these stock markets have had high returns. These conditions have created an interesting scenario for investigating the relationship between stock market development and economic growth. However, this opportunity has largely been neglected as the research on African stock market development is limited in developing economies relative to research conducted in developed countries. Furthermore, the research that has been conducted on the relationship between stock market development and economic growth in Africa, has generated inconclusive and conflicting results, in addition to this, the institutional quality of African countries is disregarded in most studies when the stock market development and economic growth nexus is analysed. Therefore, this study aims to explore the relationship between stock market development and economic growth, incorporating institution variables to account for the institutional quality of African countries to provide clarity in this context. To achieve this, two sets of research hypotheses were created the first set aims to determine whether stock development has an influence on economic growth. The second set is to determine if there is any causal relationship between stock market development and economic growth. The study utilizes System Generalized Method of Moments models to examine the effect of stock market development on economic growth, in 18 African countries for the period 2003- 2016. The results indicate that market capitalization has a positive influence on economic growth whilst, contrastingly liquidity in the form of value traded has a negative effect on economic growth. The study further analyses the causal relationship between stock market development and economic growth, by employing the recently developed PVAR-Granger causality test. However, before this is done several Pedroni cointegration tests were first conducted to establish whether a long-term relationship exists between stock market development and economic growth, which revealed that no strong evidence of cointegration exists necessitating the use of a PVAR-Granger causality test. The PVAR-Granger causality test reveals that stock market development granger causes economic growth, irrespective of the stock market development measure used and there is no feedback effect from economic growth. The unilateral causality established in this study flowing from stock market development to economic growth supports the supply-leading hypothesis. The overall results of this study demonstrate that there is ambiguity on the impact of stock market development on economic growth, as the measures of stock market development have contrasting impacts on economic growth. The size component of stock market development in the form of market capitalization has positive influence whilst, liquidity in form of total value traded has a negative effect. However, the causal relationship is clearly shown to be unilaterally flowing from stock market development to economic growth.

- Description: Rhodes University was awash with political tension and activity in the 2015 and 2016 academic years. The University had been the scene of radical protests and demands for change by students. The #RhodesMustFall, #FeesMustFall and the #RUReferenceList protests at Rhodes University started debates, conversations and public lectures amongst students and staff on and off social media on aspects of decoloniality, transformation, free education, issues of safety on campus and gender-based violence (Grocott’s Mail, 2015b). However, very little of this was reflected in the election campaigns of political parties and seemingly, in student engagement with political processes, at least as reflected in this election. The three biggest political parties in South Africa, and the only ones that contested Ward 12 (Rhodes) ANC, EFF, and the DA, were active on social media aiming to directly engage with constituents and draw citizens to the polls. All the parties had former and current Rhodes University students as candidates for councillor. There was a substantial engagement by students on social media, on the Rhodes SRC Facebook page, and on Twitter. However, only 39% of registered students, turned out to cast their vote on election day (IEC, 2016b). This study examines the interpretations and meaning-making amongst young people at Rhodes University, of the political party messages during the 3 August 2016 local government elections on social media. In addition, the study sought to understand whether youth at Rhodes (Rhodes University) actively sought out political party messages on social media (by following the ANC, DA, EFF Facebook and Twitter accounts), or were the messages incidental on their timelines (for example, following news organisations). Finally, the study sought to understand whether the media messages resonated with them and spoke to the issues faced by young people on the campus. The research used qualitative thematic content analysis and focus group discussions to examine the relationship between the content provided by the political party messages and the audience’s process of making sense and derived meaning from the content. Six focus group discussions were convened. This study found that young people are social media enthusiasts, they actively sought election related content on social media by following the Twitter and Facebook accounts of the parties, and from news organisations. Furthermore, the study discovered that, although, young people engaged with the political party messages on social media, they did not feel like the messages were targeted at them, and as such they felt the messages did not speak to them and the issues they face.

- Description: Establishing the associations between fish and their habitats can aid in the monitoring of fish stocks and the design of effective marine protected areas (MPAs). Baited remote underwater stereo-video systems (stereo-BRUVs) are now commonly used to asses fish populations. The habitats seen in the video footage of stereo-BRUVs can be used to link fish fauna to preferred habitat types. However, the application of bait potentially attracts fish from surrounding habitats, and might result in a biased understanding of fish–habitat associations. A field study was conducted in the Tsitsikamma National Park MPA to determine the effect of bait on fine-scale fish–habitat associations, using remote photographic and video methods. The study was conducted over the summer season of 2015 and 2016. Data were collected within a 1x1 km shallow (9–44 m) reef complex. Within the sampling area, 944 photo-quadrats of the macrobenthos were taken 30 m apart by means of a drop camera. By separating the macrobenthos into broad taxonomic groups, five habitat types were identified, namely Shallow Sand, Shallow Reef, Deep Reef, Deep Sand and Patch Reef. The results show that even on a fine scale, depth is an important predictor of macrobenthic distribution and assemblage structure. Baited (stereo-BRUVs) and unbaited (stereo-RUVs) surveys were then conducted to sample the fish community in the same area during the period under study. Higher abundances of fish were observed in reef than in sandy habitats, and bait was seen to have a positive effect on species richness and fish abundance. When comparing habitats, fish abundance and composition on reef habitats were significantly different from sand habitats. This was observed in both the stereo-RUVs and stereo-BRUVs methods. High counts of roman (Chrysoblephus laticeps), fransmadam (Boopsoidea inornata) and steentjie (Spondyliosoma emarginatum) in reef habitats were contrasted by high counts of white sea catfish (Galeichthys feliceps), evil-eye puffer (Amblyrhynchotes honckenii) and lesser guitarfish (Rhinecanthus annulatus) in sandy habitats. Overall, the underlying patterns in fish diversity recorded with the two video methods were generally comparable. However, stereo-RUVs appeared to be unable to detect species that were present in sand habitats, while stereo-BRUVs increased the number and abundance of species recorded in all habitat types. In the stereo-RUVs footage, differences between reef habitats were dampened by the presence of highly abundant fish species. In the stereo-BRUVs footage, although bait appeared to have an effect on the observed fish assemblage, this manifested in an increase in species richness, higher fish abundances and a better overall ability to detect fish–habitat relationships. As such, stereo-BRUVs are considered a robust, effective and recommended method for detecting fish–habitat relationships, even over a fine scale.

- Description: Zakes Mda is a prominent post-apartheid black South African novelist whose style has been described as experimental. He also wrote plays intended to ‘rally people to action’ during the apartheid years. The changes in the political and social situation in South Africa since 1994 have had significant implications for those writers and artists who produced protest literature and art. The changes in Mda’s own practice and approach to art are themselves quite telling. His experimental novels place him among those African artists pioneering a new chapter for black South African art and the self-reflexive nature of his novels suggest that he is aware of the fact and is consciously forming and reforming his ideas about what it means to be an artist in post-apartheid South Africa. This study will unpack the role of the artist and the function of art in the becoming new South Africa as represented in Zakes Mda’s novels, thereby hypothesizing Mda’s aesthetic philosophy, as may be deduced from his practice, for what an African artist and art should be. This will be done first by locating Mda in the debates around art and literature within the sociopolitical context of a South Africa in transition. Despite the fact that when it comes to public action in the post-apartheid situation, Mda distinguishes between his own role in society as an artist who is a social activist and the role intended for his work, his own novels reveal a desire for the artefact (or artwork) to have a developmental, educational or conscientizing function. This is evident in representations of the effects of art in what this study proposes to be his extended South African black Kunstlerroman, which spans three novels. It is also demonstrated in his ekphrastic novel, The Madonna of Excelsior, in which visual art is interpreted in the process of description, thereby educating the reader. Not only that, but the reader is made into an ‘almost viewer’ and taught how to ‘see’ art. What emerges in the process of this study is Mda’s aesthetic philosophy or what may be termed his ‘aesthetics of liberation’ concerning the role of the artist in post-apartheid South Africa, a suitable African audience and how art works theoretically, as expressed through his fiction.

- Description: Four different techniques to make taxonomic decisions concerning different species in Scarabaeinae are being investigated. Firstly, I made measurements of the body dimensions which are plotted on a two dimensional graph. This method is successfully used to erect one new species, Copris crassus Deschodt and Davis, 2015, and to establish the synonymy of Copris bihamatus Balthasar, 1965 with Copris fidius (Olivier, 1789). Thereafter the classical or traditional comparative method is used to propose seven new species Scarabaeolus soutpansbergensis (Deschodt and Davis 2015), Scarabaeolus megaparvulus (Davis and Deschodt 2015), Scarabaeolus niemandi (Deschodt and Davis 2015), Scarabaeolus carniphilus (Davis and Deschodt 2015), Scarabaeolus ermienae (Deschodt and Davis 2015), Scarabaeolus planipennis (Davis and Deschodt 2015) and Scarabaeolus afronitidus (Davis and Deschodt 2015) and formally synonymise Scarabaeolus vansoni (Ferreira, 1958) with Scarabaeolus lucidulus (Boheman, 1860) and Scarabaeolus xavieri (Ferreira, 1968) with Scarabaeolus andreaei (zur Strassen, 1963). Morphometric measurements of external structures of a group of flightless relict beetles in the tribe Canthonini are used to compile a nexus file which is analysed with computer software. The interpretation of these results is used here to support the erection of a new genus Drogo Deschodt, Davis & Scholtz 2016, Lastly I analysed the DNA sequences of specimens from different species belonging to a species complex in the genus Epirinus Reiche, 1841 occurring over a wide geographic range. These sequences are used together with external morphological characters to propose the synonymy of Epirinus hluhluwensis Medina & Scholtz 2005 and Epirinus ngomae Medina & Scholtz 2005 with Epirinus davisi Scholtz & Howden 1987.

- Description: While research has explored the risk factors that contribute to alcohol use during pregnancy among South African women, such studies have mostly been quantitative in nature. There is a growing body of research that contextualises and articulates the attitudes, beliefs, and underlying motivations that influence drinking during pregnancy. However, few qualitative studies explore the cultural, economic, familial, and social contexts within which drinking during pregnancy takes place. Studies which have explored these contexts have been conducted in other geographical regions such as Australia, Canada, New Zealand, and the United States but their findings are not generalisable to South Africa. Drawing on a feminist poststructuralist as well as a narrative-discursive approach including Foucault’s (1978) theory of power, this study sought to explore women’s narratives of the personal and interpersonal circumstances under which drinking during pregnancy takes place in terms of the discourses used to construct these narratives and the subject positions made available within these discourses. This allowed for the practice of alcohol use during pregnancy to be understood within the social and cultural narratives, practices, and discourses around pregnancy as well as gendered and social relations. Using the narrative interview method set out by Wengraf (2001), thirteen, unemployed ‘Black’ women from an area in the Eastern Cape were recruited and interviewed. Seven discourses emerged from the narratives namely, a discourse of ‘stress and coping’ ‘hegemonic masculinities’, ‘peer pressure’, ‘disablement and developmental delay’, ‘good mothering/appropriate pregnancies’, ‘culture’, and ‘religion’. These discourses informed the five narrative categories which emerged: narratives about the pregnancy, narratives about the drinking, narratives that justify/explain drinking, narratives that condemn the drinking, and narratives about the women knowing the effects of drinking during pregnancy. Within these narratives, the women mainly positioned themselves as dependent on alcohol during their pregnancies in order to cope with stress caused by various circumstances which were mainly centred on a lack of support from their partners, paternity denial, infidelity and unreliableness. As such, the women in this study mainly justified their drinking during pregnancy and in constructing this narrative, the ‘stress and coping’ discourse as well as the ‘male/masculine provider’ discourse were mainly drawn upon. In reflecting on this analysis, this study argues that alcohol use during pregnancy should be understood within the broader environmental and social context that makes a pregnancy challenging and/or difficult and thus necessitates drinking during pregnancy. Recommendations for future research include expanding the diversity of participants as well as interviewing healthcare providers and women who are currently pregnant, drinking, and part of an intervention aimed at addressing alcohol use during pregnancy so as to obtain a holistic understanding of engaging in this practice. The study makes key recommendations for interventions in practice to help work towards ensuring that the practice of alcohol use during pregnancy is not individualised, decontextualized, and stigmatised.

From ‘cleanliness is next to Godliness’ to ‘without perfect health, there is nothing’: discourses of healthy lifestyle in the construction of young adult identities in urban South Africa

- Description: This research explores popular constructions of “healthiness” as individual lifestyle choices in the context of contemporary South African consumer culture, and how these constructions relate to formations of subjectivity. This is a qualitative study conducted within a social constructionist, theoretical framework. Data was collected using in-depth, semi structured interviews and are analysed using a Foucauldian inspired version of discourse analysis. A critical stance is taken towards the assumption in these discourses that their version of healthiness is always and unquestionably positive. Special attention is paid to the lifestyle and marketing media discourses appropriated in understandings of personal health through self-management, and of the optimization of health in the pursuit of well-being. The ways in which different discourses of healthiness facilitate the construction of specific identities are considered in order to untangle some of the problems created by the moralism underpinning popular consumer health discourse. How constructions of healthiness and aspirant healthy lifestyles support, and are supported by, the ideologies and practices of neoliberal capitalism are also explored. From this perspective, healthiness as lifestyle consumption choices can be seen as an ideological apparatus that produces the subjects necessary to reproduce the social order (Althusser, 2001), functioning not only positively amongst the social classes with the leisure and economic resources to pursue these options, but also negatively as victim-blaming of those who are excluded. The argument here is not that health is bad or that people should not be bothered with activities aimed at promoting good health, but that in a context where the concept of health is idealised as always positive and beneficial, the potentially harmful consequences of some of the health discourses we make use of may be occluded. This idealisation of health or ‘healthism’ may also function to divert attention away from some of the challenges to health that are not the direct result of personal behaviours and are unlikely to be remedied through individually focussed interventions, for example, inequality and inadequate access to basic resources. Six discourses which were used to construct understandings of health are analysed. These include Happiness, Freedom, Control, Care, Balance and Goodness. The ways in which these discourses played a role in constructing the kinds of subject positions which were made available to participants, and the possible implications this has, are explored in depth.

- Description: The appropriateness and effectiveness of the field of psychology and its branch psychotherapy has been met with fierce criticisms especially in contexts outside of Western or Euro American or urban Southern Africa. This thesis explores attitudes, views and beliefs of rural ‘black’ communities on psychotherapy (the healing process of the mind and soul). It is important to understand how the healing process of the mind and soul is constructed and practised in South African black rural communities, and this remains an imperative of psychology. The study takes an exploratory qualitative research approach. Nine participants from two rural communities in Kwa-Zulu Natal were interviewed through face-to-face semi-structured interviews. Thematic analysis was utilised as a method of data analysis. The study employed social constructionism and Afrocentricity as theoretical points of departure. The findings were understood through employing Afrocentricity theory underpinned by post-colonial theory. Four main themes were derived with supporting subthemes. The themes indicate that rural black communities’ attitudes, views, and beliefs on psychotherapy are at variance with the Western perspective of psychotherapy. This is further associated with the practise of psychotherapy in rural black communities. The findings of this study can possibly assist in new understandings of psychotherapy as constructed in different contexts and instigate future research to be conducted in often-neglected areas such as rural communities.

- Description: Forensic identification of abandoned and suspected infanticide cases admitted to the South African Forensic Pathology Services is often impossible due to decomposition of the remains. In these cases, investigation of suspected criminal activity is almost never pursued. Ancillary tests in the form of anthropological and molecular analyses can assist with the forensic identification of perinatal remains. To provide fundamental information about bone development of perinatal skeleton, osteological and genetic techniques focusing on the pars basilaris, pars lateralis, sternal rib and left femur were used. Samples were obtained from unidentified and unclaimed remains originating from the Johannesburg Forensic Pathology Service (JFPS). To provide a biological age to individuals in the collection, dental aging was used to categorize remains for comparisons with anthropological and molecular data. A molecular protocol was designed to sex individuals using the X-linked G6PD and Y-linked SRY genes. Bone development was studied using osteometric and morphological data of dry bone remains coupled with bone mineral density analysis (Micro-CT). The methylation levels of CpG rich sites within the promoter region of selected bone-associated genes were incorporated to examine silencing of genes during development. Osteological results support the use of the pars basilaris, pars lateralis and femur for age-at-death estimations as well as provide the foundation for dry bone aging criteria for South African individuals. Data compared with established skeletal aging standards indicated developmental differences between populations. Through the use of animal models and the perinatal sternal rib tissue, insights and precautions into the use of post mortem bone derived RNA for forensic applications is communicated. The methylation status of CpG rich sites within the promoter regions support the hypothesis for interdependent machinery involving selected genes during early bone development. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2019

- Description: The Donald C. Backer Precision Array to Probe the Epoch of Reionization (PAPER, Parsons et al., 2010) was built with an aim to detect the redshifted 21 cm Hydrogen line, which is likely the best probe of thermal evolution of the intergalactic medium and reionization of neutral Hydrogen in our Universe. Observations of the 21 cm signal are challenged by bright astrophysical foregrounds and systematics that require precise modeling in order to extract the cosmological signal. In particular, the instrumental leakage of polarized foregrounds may contaminate the 21 cm power spectrum. In this work, we developed a formalism to describe the leakage due to instrumental widefield effects in visibility-based power spectra and used it to predict contaminations in observations. We find the leakage due to a population of point sources to be higher than the diffuse Galactic emission – for which we can predict minimal contaminations at k>0.3 h Mpc -¹ We also analyzed data from the last observing season of PAPER via all-sky imaging with a view to characterize the foregrounds. We generated an all-sky catalogue of 88 sources down to a flux density of 5 Jy. Moreover, we measured both polarized point source and the Galactic diffuse emission, and used these measurements to constrain our model of polarization leakage. We find the leakage due to a population of point sources to be 12% lower than the prediction from our polarized model.

- Description: The aim of this research is to bring the literature on political agency and economics together in an analysis of whether social movements can play an important role in economic development in post-apartheid South Africa. The entrenched discourse of sluggish growth and high inequality in post-apartheid South Africa can largely be attributed to the political decision to implement a neoliberal economic development orthodoxy. On the one hand, there is an urgent need to shift the economic development model to an alternate developmentalist model. However, no clearly articulated alternative developmental model has emerged. As a result, economically, South Africa is seemingly stuck. On the other hand, the selection of an economic development model and change in macroeconomic policies requires a political shift. Politically, formal politics has assumed the form of neoliberal democracy, characterised by a largely centralised state and the usurpation of the state and institutions by a national bourgeoisie. Social movements have emerged in response to the failure of neoliberalism to fulfil the promises of early post independent periods. They have been largely successful at highlighting the injustices and the inequalities in the country. However their ability to influence structural economic development has come into question. Firstly, social movements and their “politically destabilising distributive demands” have faced repression from the state as the state and institutions are aligned behind the interests of capital under a neoliberal democracy. Secondly, social movements in South Africa have been largely ideologically under-developed. They have been largely fragmented and tended to contest specific single issues rather than aiming to shift the deeper underlying systemic drivers behind the symptomatic immediate discomforts. The economic dimensions of such a shift are particularly unclear. This fragmentation and apparent lack of economic pragmatism make management or suppression of disruptive movements by the state relatively easy. The research uses a contrast between the Latin American social movements against a South African background in order to see what lessons South Africa can draw from social movements in Latin America. The Latin American case is cautiously more positive and provides comparably more sanguine lessons. In this way, this research seeks to construct a more comprehensive framework for the further study of social movements in South Africa and their potential impact on economic development in South Africa.

- Description: Much of the growth in sexualities‘ research has taken the form of large scale surveys, but there is also increased interest in qualitative approaches that provide useful insights into the experiential and subjective aspects of sexuality, and illuminate the social and cultural contexts shaping these experiences. The reason for this research is to provide a richer understanding of the language that young people employ when speaking about sexuality. This study examines young adults‘ talk about sexualities with a special focus on the way in which colloquial terms are deployed in this talk and through the presence of gendered and/or heteronormative assumptions. Data consisted of posts off a student-led social media site and the study design employed was a validity check group interview. The social media site allowed its followers to post anonymously about a range of sexualities related issues. Data were analysed thematically, using a deductive, critical, and post-structuralist approach with key insights drawn on from Michael Foucault, Adrienne Rich, Gayle Rubin, Judith Butler and Rosalind Gill. Three overarching themes emerged: young adults spoke to sexual practices, sexual subjectivities and sexual desires. A major focus of this talk is casual sex. This talk showed that there are attempts to undermine gendered and heteronormative power relations, for example, non-normative sexual experiences were not seen as deviant, although those who were engaging in monogamy and casual sex were constructed as deviant sexual subjects. Yet underpinning of these power relations still took place, for example, in the female missing discourse of desire, the internalisation of male sexual desires over female sexual desires and the sexual double standard. There was a clear divide between the sexual practices and sexual subjectivities that were considered to be good and bad. This research therefore has the potential to benefit sexuality interventions by bringing into sharp focus the actual experiences of young adults.

- Description: Bantu verbal suffixes, also known as extensions, follow a rather rigid pattern when they attach to the verb. Studies (e.g. Hyman 2002, Good 2005, 2007, among others) have shown that the order followed by these extensions is: Causative, Applicative, Reciprocal, Passive (CARP). Although this pattern is widespread across Bantu, some variations in the ordering of these extensions have been observed in some languages (Kathupa 1991, Simango 1995, Sibanda 2004, among others), which suggests that the template is not as rigid as one might think. This study investigated the morphotactic constraints between four verbal extensions in isiXhosa, the Causative, Applicative, Reciprocal and Passive. It focused on the morphotactics of the transitivising extensions (Causative and Applicative) in the first instance, and morphotactics of the detransitivising extensions (Reciprocal and Passive) in the second instance. The study found that although the co-occurrence of causatives and applicatives is a regular feature in Bantu languages, isiXhosa has restrictions on the co-occurrence of these extensions on some verbs. The study also found that although Causative-Applicative is the expected order the language permits Applicative-Causative in certain contexts. With respect to the detransitivising extensions, the study revealed that there are limited contexts in which these extensions co-occur and, crucially, that these extensions are freely ordered in the language.

- Description: Bantu verbal suffixes, also known as extensions, follow a rather rigid pattern when they attach to the verb. Studies (e.g. Hyman 2002, Good 2005, 2007, among others) have shown that the order followed by these extensions is: Causative, Applicative, Reciprocal, Passive (CARP).

- Description: There are many diseases and illnesses in the world that require new drug treatments and chitin has been shown to produce chitooligomeric derivatives which exhibit promising antimicrobial and immune-enhancing properties. However, the rate-limiting step is associated with the high recalcitrance of chitinous substrates, and low hydrolytic activities of chitinolytic enzymes, resulting in low product release. To improve and create a more sustainable and economical process, enhancing chitin hydrolysis through various treatment procedures is essential for obtaining high enzyme hydrolysis rates, resulting in a higher yield of chitooligomers (CHOS). In literature, pre-treatment of insoluble biomass is generally associated with an increase in accessibility of the carbohydrate to hydrolytic enzymes, thus generating more products. The first part of this study investigated the effect of alkali- (NaOH) and acid pre-treatments (HCl and phosphoric acid) on chitin biomass, and chemical and morphological modifications were assessed by the employment of scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Energy-Dispersive X-ray spectrometery (EDX) and x-ray diffraction (XRD). Data obtained confirmed that pre-treated substrates were more chemically and morphologically modified. These results confirmed the fact that pre-treatment of chitin disrupts the structure of the biomass, rendering the polymer more accessible for enzymatic hydrolysis. The commercial chitinases from Bacillus cereus and Streptomyces griseus (CHB and CHS) are costly. Bio-prospecting for other chitin-degrading enzymes from alternate sources such as Oidiodendron maius, or the recombinant expression of CHOS, was a more economically feasible avenue. The chit1 gene from Thermomyces lanuginosus, expressed in Pichia pastoris, produced a large range CHOS with a degree of polymerisation (DP) ranging from 1 to above 6. TLC analysis showed that O. maius exhibited chitin-degrading properties by producing CHOS with a DP length of 1 to 3. These two sources were therefore successful in producing chitin-degrading enzymes. The physico-chemical properties of commercial (CHB and CHS) and expressed (Chit1) chitinolytic enzymes were investigated, to determine under which biochemical conditions and on which type of biomass they can function on optimally, for the production of value-added products such as CHOS. Substrate affinity assays were conducted on the un-treated and pre-treated biomass. TLC revealed that chitosan hydrolysis by the commercial chitinases produced the largest range of CHOS with a DP length ranging from 1 to 6. A range of temperatures (35-90oC) were investigated and CHB, CHS and Chit1 displayed optimum activities at 50, 40 and 45 oC, respectively. Thermostability studies that were conducted at 37 and 50oC revealed that CHB and CHS were most stable at 37oC. Chit1 showed great thermostablity at both temperatures, rendering this enzyme suitable for industrial processes at high temperatures. pH optima studies demonstrated that the pH optima for CHB, CHS and Chit1 was at a pH of 5.0, with specific activities of 33.459, 46.2 and 5.776 μmol/h/mg, respectively. The chain cleaving patterns of the commercial enzymes were determined and exo-chitinase activity was exhibited, due to the production of CHOS that were predominantly of a DP length of 2. Enzyme binary synergy studies were conducted with commercial chitinases (CHB and CHS) on colloidal chitin. Studies illustrated that the simultaneous combination of CHB 75%: CHS 25% produced the highest specific activity (3.526 μmol/h/mg), with no synergy. TLC analysis of this enzyme combination over time revealed that predominantly chitobiose was produced. This suggested that the substrate crystallinity and morphology played an important role in the way the enzymes cleaved the carbohydrate. Since CHOS have shown great promise for their antimicrobial properties, the CHOS generated from the chitinous substrates were tested for antimicrobial properties on Bacillus subtilis, Escherichia coli, Klebsiella and Staphlococcus aureus. This study revealed that certain CHOS produced have inhibitory effects on certain bacteria and could potentially be used in the pharamceutical or medical industries. In conclusion, this study revealed that chitinases can be produced and found in alternate sources and be used for the hydrolysis of chitinous biomass in a more sustainabe and economically viable manner. The chitinases investigated (CHB, CHS and Chit1) exhibited different cleaving patterns of the chitinous substrates due to the chemical and morphological properties of the biomass. CHOS produced from chitinous biomass exhibited some inhibitory effects on bacterial growth and show potential for use in the medical industry.

- Description: This dissertation is an analysis of the enablements and constraints navigated by 43 students from different academic years within the Department of Accounting, Rhodes University, in their pursuit of obtaining the postgraduate Diploma in Accounting (DipAcc) qualification. Passing this diploma year entitles students to become Trainee Accountants, which is one of the requirements for their ultimate goal of becoming a chartered accountant. In the course of semi-structured, face-to-face interviews conducted for this study, students from across the four years of the professional degree programme, shared what had helped or hindered them on their journeys to and through Rhodes University, and within the Department of Accounting at this university. Focus group discussions were then held with academics from the department, where the student participants’ experiences were shared. The responses of the members of the focus groups confirmed many of the student participants’ experiences as did interviews with representatives from the South African Institute of Chartered Accountants (SAICA). These representatives also spoke about students’ experiences at other campuses. To determine how localised the student participants’ experiences were, selected individuals from a number of other Departments or Schools of Accounting at SAICA-accredited institutions in South Africa were also interviewed. SAICA representatives also discussed the ‘pervasive skills’ which trainee accountants are expected to acquire. The perspectives from these different groups, have provided validation of the student research participants’ experiences. Critical Realism and Social Realism were used as theoretical underpinnings while Social Realism, Bernstein’s Pedagogic Device, Legitimation Code Theory and New Literacies Theory were used as explanatory theories. Using these theories, the participants’ experiences were analysed and could be understood in a different way. This dissertation reveals how this unequal privileging of individuals as a result of the existing structures is perpetuated at university level. It is the poorer students from under-resourced schools who generally struggle with the language and the practices and ways of being required for success at university. Student participants’ experiences of constraint and enablement arose primarily in the areas of the finances required for tuition and living expenses while at university; having English as a language of learning; and difficulties experienced with taking advantage of the learning opportunities within the department. Research participants also spoke about their experiences of transformation in terms of both student protests, and a mentoring programme which assisted them in gaining access to the practises and ways of being required for the discipline. In so doing they were inducted into the discipline’s community of practice. This dissertation has assisted in providing an understanding of what has helped and what has hindered students at Rhodes University, on their journeys towards obtaining the Postgraduate Diploma in Accounting qualification. It has also provided insight into the mechanisms which lie behind these experiences. This study will provide practitioners and policy-makers with the opportunity to be better informed about students’ struggles, to contemplate their interactions with students and to identify, remove or reduce unnecessarily burdensome hurdles. Equally and perhaps more importantly, this study and the work which emerges as a result of this research, will provide students with tools to assist them in their academic journeys, to manage essential hurdles, and to eliminate or avoid unnecessary hurdles.

- 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: The pedagogical practice choices teachers make when teaching writing in Grade-9 English first- language classrooms, as well as the extent to which these pedagogical practices appear to enable or constrain learners’ acquisition of writing skills as per grade-specific curricular expectations, are the focus of the study. It draws from Bernstein’s (1971) curriculum and society theory, as well as genre theory. Located within the qualitative case study approach, it is designed to investigate the reasons for Grade-9 English first-language learners’ underperformance in Paper 2, the composition component of the Namibian external examinations. Drawing from the interpretivist paradigm, the study uses one-on-one interviews, semi-structured classroom observations, as well as documentary evidence of the Namibian English first-language syllabus and examples of learners’ written work, to generate data. The research site and study participants were purposefully selected. The study involves two Grade-9 English first-language teachers and classrooms at one Namibian High School, and took place from the second to the third terms of 2017.

- Description: The emergence of visual art spaces over the past few decades on the African continent invites art practitioners, historians and critics to re-examine the conditions of production, diffusion and reception of contemporary art of Africa. In this thesis I critically engage with these conditions in relation to artworks and practices of the Democratic Republic of Congo, considering the curatorial logic that has governed the ‘global art world’. I focus on the Kin ArtStudio as my main case study. I undertook research within this art space in 2016, from the 10th of April to the 15th of June, and again from the 16th of July to the 12th of September. My position as a participant observer turned out to be as engaging as informative. The Kin ArtStudio is a Kinshasa-based visual art platform founded in 2011 by the Congolese artist Vitshois Mwilambwe Bondo. It was established out of the will to empower emerging artists in that specific context, and facilitate the negotiation that the legitimization of their creations entails in today’s global art and cultural dynamics. In order to evaluate the stakes of such negotiation, I start with reviewing the existing mechanisms, trends and networks that have legitimized visual art productions of the Democratic Republic of Congo on a global stage, as exemplified by the Beauté Congo – Congo Kitoko exhibition (2015). Then, my enquiry evolves towards specificity, towards the immediacy and the subjectivity that characterize Kinshasa's urban and socio-cultural context, and visual art practices therein. Subjectivity also applies to my four months immersive experience with that art space. Drawing from my observations, setbacks, hopes and recent academic and practical debates around contemporary art practices on the African continent, the role those art spaces can play in the curatorship, circulation, reception and commodification of contemporary art productions cannot be underestimated. While operating in lasting postcolonial settings, they are going through the negotiation of their global and translocal situatedness, which can in turn lead to new legitimizing narratives. These will more appropriately inform understandings of contemporary art practices of Africa, challenging the identifying prism sustained by the ‘global art world’.

- Description: The emergence of visual art spaces over the past few decades on the African continent invites art practitioners, historians and critics to re-examine the conditions of production, diffusion and reception of contemporary art of Africa. In this thesis I critically engage with these conditions in relation to artworks and practices of the Democratic Republic of Congo, considering the curatorial logic that has governed the ‘global art world’. I focus on the Kin ArtStudio as my main case study. I undertook research within this art space in 2016, from the 10th of April to the 15th of June, and again from the 16th of July to the 12th of September. My position as a participant observer turned out to be as engaging as informative. The Kin ArtStudio is a Kinshasa-based visual art platform founded in 2011 by the Congolese artist Vitshois Mwilambwe Bondo. It was established out of the will to empower emerging artists in that specific context, and facilitate the negotiation that the legitimization of their creations entails in today’s global art and cultural dynamics. In order to evaluate the stakes of such negotiation, I start with reviewing the existing mechanisms, trends and networks that have legitimized visual art productions of the Democratic Republic of Congo on a global stage, as exemplified by the Beauté Congo – Congo Kitoko exhibition (2015). Then, my enquiry evolves towards specificity, towards the immediacy and the subjectivity that characterize Kinshasa's urban and socio-cultural context, and visual art practices therein. Subjectivity also applies to my four months immersive experience with that art space. Drawing from my observations, setbacks, hopes and recent academic and practical debates around contemporary art practices on the African continent, the role those art spaces can play in the curatorship, circulation, reception and commodification of contemporary art productions cannot be underestimated. While operating in lasting postcolonial settings, they are going through the negotiation of their global and translocal situatedness, which can in turn lead to new legitimizing narratives. These will more appropriately inform understandings of contemporary art practices of Africa, challenging the identifying prism sustained by the ‘global art world’.
