- Description: Online communication has become a universal phenomenon, and a significant consequence of computer mediated communication (CMC) is the influence it has on self-disclosure. The aim of the present study was to explore and describe young adults’ perceptions of online self-disclosure, specifically what young adults’ self-disclose online and what psychosocial factors impact upon self-disclosure online. Bronfenbrenner’s Bioecological Systems Theory and the Johari Window were utilised as the theoretical framework of the study. The present study utilised a qualitative approach and was exploratory and descriptive in design. The sample size of the present study was 13, and semi-structured interviews were utilised as the method of data collection. The data obtained was analysed using thematic analysis, as outlined by Braun and Clarke. Six main themes were identified, namely Types of Online Experience, Online Self-disclosure, Information Disclosed Online, Differences between Online and Offline Self-disclosure, Privacy and Online Regrets. The findings of the present study will generate a better understanding of young adults’ online self-disclosure and can be utilised for future research.

Young men’s talk about menstruation and hegemonic masculinity in the South African context: a discursive analysis

- Description: Current research in the sub-Saharan and other resource poor contexts indicates the largely negative social constructions of menstruation and menstruating women. Young men have been shown to reproduce these negative constructions and reinforce the stigmatized status of menstruation in these contexts. To my knowledge no studies have examined the ways in which young men talk about menstruation and menstruating women in South Africa. In this research, I aimed to explore the ways in which young men (in a resource poor area in the Eastern Cape) talk about menstruation in with their male peers in a focus group context and how this talk serves to enable specific subject positions (both masculine and feminine) that may reproduce, comply with and resist constructions of hegemonic masculinity (as outlined in previous South African research). By drawing on Raewyn Connell’s influential framework of masculinities and augmenting this with Margaret Wetherell and Nigel Edley’s contributions, this research adds to the growing body of research on masculinities in the South African context. I utilized a discursive framework in which to understand the interpretative repertoires drawn on in everyday talk about menstruation and the specific subject positions made available by these. Purposive sampling was used to recruit a total of 37 participants from two former Department of Education and Training schools in the Eastern Cape. Participants were young ‘black’ men with a mean age of 18.3 In analyzing and interpreting the data two overarching patterns emerged. In the first, the participants discursively distanced themselves from menstruation (and femininity in general) in order to avoid possible marginalisation and subordination in relation to local hegemonic masculine ideals. In doing this, the participants drew on a number of interpretative repertoires including: a dualistic repertoire, a bad (versus ideal) femininity repertoire and an abject femininity repertoire, which assisted in creating numerous subject positions. These subject positions allowed the young men to align themselves closer to hegemonic masculine ideals, and create distance by positioning menstruating women as the ‘other’. In the second overarching pattern, menstruation was constructed as a threat to masculine identity; within this construction, the young men discursively negotiated the ideological dilemmas surrounding this ‘highly feminine’ topic in ways that bolstered their positions within the gender hierarchy. Overall, hegemonic masculinities in this context were discursively reproduced and complied with in the participants’ accounts.

- Description: This study examines the changing roles of graphics journalists in the digital era at Graphics24, the largest information graphics newsroom in South Africa, in the context of their work for Netwerk24, an online news site published in Afrikaans with a strong focus on mobile-first news. The study examines the discursive construction of these new journalistic roles in the digital era where even the core conceptualisation of what journalism is, is being re-examined. It considers external factors affecting the discourse of change, drawing on a hierarchy of influences analytical model, as well as norms specific to the creation of information graphics. Data for this study was gathered by using ethnographic immersion and semi-structured interviews. This study specifically looks at graphics journalists working in a mobile-first environment, and how the pressures of producing information graphics for consumption on smartphones affects their roles. Evidence of two widely differing discourses in the Graphics24 and Netwerk24 newsrooms was found. Visual journalists in this study have created a discourse around being distinct “service providers”, rather than mobile-first journalists, who do not see the need for full integration in the fast-paced mobile news environment of Netwerk24. Word-centric journalists have, by contrast, created a mobile-first discourse. They experience the separateness of the graphics team as a barrier that impedes the creation of good information graphics for mobile phone consumption. Although this is a very localised study in a very particular context, this study contributes to broader thinking in what is a very under-researched field: The changing roles of visual journalists in the digital era and the discursive construction of these roles. The study suggests that even in the digital era where the definition of newsrooms has become much more fluid and less fixed physically, ethnographic methods can still offer a meaningful way to explore journalistic roles.

‘I don’t belong nowhere really’: the figure of the London migrant in Dan Jacobson’s ‘A Long Way from London’ and Jean Rhys’s ‘Let Them Call It Jazz’

- Description: Publisher version , In this article we compare and contrast the figure of the migrant, central to Dan Jacobson’s short story ‘A Long Way from London’ ([1953] 1958. A Long Way from London and other stories. London: Weidenfeld & Nicholson), and to Jean Rhys’s short story ‘Let Them Call It Jazz’ ([1962] 1987. The Collected Stories. New York: Norton), both of which are set in London in the early to mid-twentieth century. The main argument is that these figures, as migrants in London from South Africa and the Caribbean respectively, similarly occupy a liminal space despite stark differences in class, race and gender. In both stories this liminal space is described through evocations of London as a hostile diasporic space, lacking in hospitality, and experienced by the migrant figure as a place of confinement and incarceration. Also, both stories utilize the technique of silence or lacunae when it comes to issues of specific discrimination and abuse, such as racism or sexual exploitation. For the purposes of comparison, the character Manwera from ‘A Long Way from London’ and, Selina, the protagonist of ‘Let Them Call It Jazz’, are selected for analysis. Particularly, their respective responses (Manwera’s pride and dignity, and Selina’s recovery after a breakdown, and her musical talent) to the exigencies of migration are suggestive of ‘adaptive strength’ (Steve Vertovec and Robin Cohen [1999] 2001. Migration, Diasporas and Transnationalism. Cheltenham and Northampton MA: Elgar Reference Collection, xviii), a common feature in transnational literature which attempts to celebrate liminality and multiplicity as key characteristics of a transnational subjectivity. In addition, the protagonist of ‘A Long Way from London’, Arthur, offers a contrast to Manwera and Selina, not only because of race and class, but because he is depicted as having adapted to and assimilated into British culture, while being strangely detached from and ambivalent about both homeland and diasporic home. Varying forms of adaptive strength are portrayed in both stories, but they close with intimations of bleak futures for the migrant figures. The essay thus concludes with the observation that in these two stories, the figure of the London migrant is rendered as facing further grave challenges, and that all three figures ‘belong nowhere’ (Rhys [1962] 1987 Rhys, Jean. [1962] 1987. The Collected Stories. New York: Norton. [Google Scholar] , 175).

- Description: This study analyses the modern twenty-first century travel writing of Paul Theroux’s Dark Star Safari (2003) to reveal its sustained impetus towards colonial discursive constructions of Africa. In doing so, it will examine the continuation of colonial methods and techniques of literary representation in travel texts by illustrating the early ‘images’ of Africa and Africans as they appear in Henry M. Stanley’s non-fictional travel text Through the Dark Continent (1878) and Joseph Conrad’s fictional travel novella Heart of Darkness (1899). With the purpose of producing a critical literary analysis, this study will employ discourse analysis to interrogate the implications of the continued employment of colonial rhetoric and language by Theroux in his representations and portrayals of Africa and African citizens. It has been found that there is an unproblematised acceptance – even reverie – of colonial sentiment and nostalgia evident in representations of Africa in modern travel literature. Literary representations of this nature continue to portray Africa as the ‘savage’, ‘backward’, ‘violent’ and ‘inferior’ continent that it had signified to travel writers during the colonial epoch. Africans, as they are portrayed in this narrative tradition, are ascribed the same denotations where their subjectivities, individualities, cultures, beliefs, ideologies and personhood are encapsulated under the conceptualisation of ‘darkness’ that signifies ‘African’ as inferior to the West, Europe and North America, and therefore subject to derogation. By demonstrating the violent and damaging nature of these representations, as they remain in twenty-first century travel literature, this dissertation hopes to initiate a dialogue around the genre’s preservation of preconceptions and prejudices that continue to plague Africa and its people. This is possible through literary critique that exposes dated colonial racism and prejudice that appears in the travel literature of the post-independent age in which we now find ourselves.

- Description: The growth of the Internet has allowed fans who consume various media products, to interact and convene with other who share similar interests in online fan communities. Historically the study of fans has focused on pleasure and enjoyment as the main motivating factors why individual fans join, stay and participate in fan communities. This study, however, suggests that learning as a component of belonging has been underestimated within contemporary fan studies. Close examination of the literature of fan studies and the social practices of online fan communities reveal that these spaces may serve as fertile spaces for learning and the sharing of knowledge. Daily learning occurs within multiple spheres, including personal interests, peer culture, and academic content; all elements which can be found within fan communities. This study used the social learning theory “communities of practice” (CoP) model developed by Wenger (1998) to understand of this element of learning and knowledge sharing that seems to take places within fan communities. This study explores learning as a component of belonging to online fan communities by using the fan community of the YouTube personalities Vlogbrothers, which has named itself Nerdfighteria, as a case study. Through a qualitative research approach, which includes participation observation methods and qualitative interviews, this thesis has analysed the fan community Nerdfighteria, and used two Nerdfighter fan Facebook groups, the global NERDFIGHTEIRIA and local Nerdfighters South Africa, as case studies to evaluate whether the elements of learning taking place within these spaces serves as a motivating factor for belonging and participation. The results of this research support the idea that learning plays a role within the fan community Nerdfighteria and thus that it functions as a CoP. Fans within the global NERDFIGHTERIA Facebook group use this fan space to discuss and debate content related to their media of choice; thereby learning and acquiring knowledge as a CoP. The Nerdfighters South Africa Facebook group, despite the learning potential, fails to function as a CoP because it is no longer functionally allows for shared learning. Online fan communities, this research found, have the potential to serve as functioning communities of practice (CoP) only if they embody the characteristics and practicalities consistent with a learning space. Overall these fan groups may be categorised as communities of interests but sub-sections within these communities fit the criteria of a community of practice due to the kind of learning that is taking place. This research supports an alternative, yet promising, approach to the study of fan online communities which prioritises learning.

- Description: “Forgetting Ntaba kaNdoda”: Reciting Performative Memories at the Ntaba kaNdoda Monument serves as a theoretical examination of the Ntaba kaNdoda Monument as a commemorative marker. My mini-thesis unpacks the notions of memory and performative memorialisation at a nationalist memorial in the former Ciskei by examining the concepts of place, memory and memorialisation, which are theoretically integral in my professional practice. This research initiates an investigation into the effects on memory in a situation where the construction of the Monument disrupted an efficacious memorialisation by the communities of Ntaba kaNdoda. In my accompanying MFA exhibition Forgetting Ntaba kaNdoda, I explore notions of place, memory and memorialisation through installations of a variety of photographic processes that are based on what I call ‘de-monumental’ and performative monuments (Widrich2014). The written component of my MFA submission relates directly to my professional art practice, developing and situating it within a relevant context. In my mini-thesis, I consider photographers working with notions of place, memory and memorialisation. Lebohang Kganye and Nassim Rouchiche’s works retrace and recall past memory in the present, while David Goldblatt and Cedric Nunn, who have photographed the Ntaba kaNdoda Monument, point the viewer to the values and histories of the communities most affected by colonialism and apartheid. These photographers’ works operate as mnemonic devices that seek to translate a lived experience at a particular place. I use Widrich’s (2009; 2014) conception of “performative monuments”, Lippard’s (1997) “sense of place” and Nora’s (1989) “lieu[x] de mémoire” and “milieux de mémoire” in approaching my professional art practice and my research into the Ntaba kaNdoda memorial. Using these entwining nodes of theories in formulating what I term ‘demonumentalisation’ in my photography practice at the Ntaba kaNdoda Monument, my photography functions as both performative memorialisation and de-monumentalisation. Remembrance, using photography as a vehicle to represent this notion at Ntaba kaNdoda, transcends the materiality of the Monument. My exhibition, in conjunction with this mini-thesis, therefore reframes and reconfigures theNtaba kaNdoda Monument as a multiplex memory place.

- Description: A number of South African women writers have taken up chick-lit as a form of writing that enables them to reflect on the experiences of the modern woman in post-apartheid South Africa. The protagonists portrayed in chick-lit narratives occupy ambiguous positions: they may have benefitted from feminist politics, which has opened new possibilities for them; however, underlying this emancipation is an implicit collusion with patriarchy. Chick-lit refuses to offer a clear-cut construct of women’s lives; instead, it suggests a problematic terrain that is inherently ambiguous and contradictory, simultaneously empowering and oppressing women. It depicts a realistic world where contemporary women critique patriarchy and attempt to break free of its stranglehold by finding new methods of self-realisation. In this article, I argue that as a genre chick-lit offers a space of recognition and reflection for women who share a similar world view and emotional knowledge that stems from a common historical experience.

- Description: Publisher version , In this article, I argue that London plays a dual role in South African writing, as a “real” city at a particular moment in history, and as a textual, imaginative space. For many South African writers, London comes to stand metonymically for English culture and literature even if their attitude toward Englishness and Empire may be one of ambivalent critique. The intertexts invoked in South African representations of London forge literary solidarities, and foreground belated postcolonial engagements with modernity that are significantly displaced from the “margin” to the “center” of modernism (and Empire) itself.

To attempt to address this lacuna in South African literary criticism, and to partially explain why Abrahams has been under-researched, I look at key moments during his early career, including the publication of Dark Testament (1942), Song of the City (1945) and Return to Goli (1953). By focusing on texts by Abrahams that were published during his time in London, I also wish to address the significance of the city in the history of South African literature, and in African anti-colonial and anti-racist thinking more broadly.

This light, strong, and affordable woven bag, often referred to as “China bag” or “Chinese tote,”1 features prominently in recent artistic practices by African artists such as Nobukho Nqaba, Dan Halter, and Gerald Machona. In this essay I examine how these artistic interventions using photography, installation, video, and performance, circulating in galleries, museums, and the streets, contribute to sociological discussions about the ways in which emerging trajectories, relationships, and identities are perceived and debated in the context of the global South.

- Description: For postcolonial societies, addressing the impact of the previous oppressive system in a bid to attain equity and social justice necessitates transformation in various spheres and sectors of society. As cradles of learning, research, and knowledge development, higher education institutions are one such sphere with a particular duty to contribute to, and embody, social transformation. However, almost 25 years after the country’s first democratic elections, the institutional cultures and structures of many South African universities still bear the imprimatur of past inequities. Existing research suggests that the success of transformation policies is influenced by the extent to which individual staff members exercise agency to effect transformative practices. But what determines whether an individual becomes an agent of change? This paper draws on the experiences of ten academic staff members who have taken actions that can be said to have contributed to shifting in important ways relations and/or practices at one university in South Africa. It adopts a hermeneutic phenomenological lens to understand the lived experiences of participants of having agency and undertaking transformative actions.

“We are white”: oral tradition, documented history and molecular biology of Xhosa clans descended from non-African forebears and their expression of this ancestry through the idiom of ancestor religion

- Description: Xhosa clan membership is symbolised by a clan-name (isiduko) and passed along the male line from father to son. This social indicator has a biological counterpart in Y chromosome DNA that passes through successive generations in the patriline. Both relate specifically to a distant patrilineal forebear or apical ancestor. The present study has involved the collection and documentation of oral-historical information relating to the descent of certain Cape Nguni clans from non-African forebears and (where possible) a review of documented accounts of such origins. The research has also included collection of buccal cells from male research participants and analysis of their Y chromosome DNA. This method indicates whether a man’s patrilineal forebear lived in Africa. Otherwise, it indicates the broad geographical region from which he originated, hence providing an additional, independent source of information relating to ancestry that can confirm or challenge claims made based on oral history. Ethnographic research into the performance of distinctive ancestor rituals by clan members explores the continuing relevance of foreign ancestry in the contemporary context of rural communities in the Eastern Cape, South Africa. The study heeds calls for the decolonisation of scholarship in various ways: methodologically, through transdisciplinary research; ontologically, by questioning the utility of the nature: culture and related dichotomies; and epistemologically, because instead of relying entirely on the western academic tradition, it takes account of other modes of knowledge production. In rejection of the notion that only one side of history is true, it records multiple voices – those of the powerful but also the ordinary. The study deals with race and racial identification, but confirms the superficiality of these constructed differences by offering evidence of their submergence in the unifying power of kinship and descent.

- Description: The Russian Wheat Aphid (Diuraphis noxia Kurdjumov, 1913) (RWA) is a serious pest of grain crops and is of considerable concern in South Africa, particularly in terms of barley grown specifically for the brewing industry. This paper highlights the effect of a small (50 ppm) increase in [CO2] on the growth rate of the four South African RWA biotypes on the SABBIErica barley cultivar. Controlled environment experiments revealed that the colony growth rate for RWASA4 was significantly lower than SA1 under ambient conditions as well as significantly lower than SA1, SA2 or SA3 under elevated CO2 conditions. The unexpected difference suggested an atypical, non-preferential feeding habit on SABBIErica, for RWASA4. The small RWASA4 colonies inflicted similar morphological damage to the significantly larger RWASA1 – RWASA3 biotype populations — indicative of potential hypervirulence under elevated CO2. The continuous feeding of RWASA biotypes causes damage to the transport system as well as substantial, catastrophic damage to mesophyll chloroplasts as well as mitochondria within the host plant's leaves. The TEM study revealed evidence of sequential/systematic degeneration of chloroplasts and mitochondria with continued aphid feeding, which we suggest is an indication of potential emergent hypervirulence under elevated CO2 conditions.

The framework addresses the limitations of manual Indicator of Compromise generation and utilises sandbox environment to perform the malware analysis in. We focus on the generation of network based IOCs from captured traffic files (PCAPs) generated by the dynamic malware analysis. The Cuckoo Sandbox environment is used for the analysis and the setup is described in detail. Accordingly, we discuss the concept of IOCs and the popular formats used as there is currently no standard. As an example of how the proof-of-concept framework can be used, we chose 100 Dridex malware samples and evaluated the traffic and showed what can be used for the generation of network-based IOCs. Results of our system confirm that we can create IOCs from dynamic malware analysis and avoid the legitimate background traffic originating from the sandbox system. We also briefly discuss the sharing of, and application of the generated IOCs and the number of systems that can be used to share them. Lastly we discuss how they can be useful in combating cyber threats.

- Description: This paper proposes a transdisciplinary framework to allow for a multifocal exploration of classroom talk practices. It draws on data from a broader study of talk in South African Grade 4 mathematics classrooms where the language of teaching and learning (English) was the home language for neither the teachers nor their students. Lesson transcript data from one teacher’s lessons on fractions are used to demonstrate how working with three strands of conceptual insight from the disciplines of psychology, sociology and linguistics conduces to a potentially richer understanding of a teacher’s use of classroom talk in mediating her students’ mathematical understanding. By drawing on elements of Vygotsky’s sociocultural psychology, we make visible in the lesson data the ways in which this teacher used the ‘everyday’ in trying to navigate her students’ towards more ‘scientific’ conceptualizations of unit fractions. By then taking up aspects of Bernstein’s sociological work, we articulate, and make visible, how societal circumstances impinge on students’ access to exploratory mathematical discourse needed for epistemological access to abstract and generalized mathematical concepts. Finally, through Halliday’s work on the power of particular linguistic registers for meaning-making, we highlight challenges in learning mathematics in and through a second language and reveal the constraints placed on students’ opportunity to maximally exploit the distinct forms of meaning contained within the mathematics register.

By then taking up aspects of Bernstein’s sociological work, we articulate, and make visible, how societal circumstances impinge on students’ access to exploratory mathematical discourse needed for epistemological access to abstract and generalized mathematical concepts. Finally, through Halliday’s work on the power of particular linguistic registers for meaning-making, we highlight challenges in learning mathematics in and through a second language and reveal the constraints placed on students’ opportunity to maximally exploit the distinct forms of meaning contained within the mathematics register.

- Description: Fish are constantly in contact with pathogens inhabiting water. High population density as well as poor hydrodynamic conditions and feeding lead to an increased sensitivity towards infections. In order to prevent major economic losses due to diseases, various medications are used for treatment and prevention of infections. The use of antimicrobial drugs in aquacultures could lead to emergence of resistance in pathogenic microorganisms. Alternatives are being sought over the last few years to replace antibiotics, and medicinal plants are one of available options for this purpose. These plants are rich in secondary metabolites and phytochemical compounds, which have an effect against viral, bacterial, and parasitic diseases in fish. Their main advantage is their natural origin and most of these plants do not represent threat for human health, the fish, and the environment. The goal of this review is to present information on the treatment of viral, bacterial, and parasitic diseases in fish through medicinal plants, with focus on the mechanisms of action of the identified secondary metabolites, fractions, or plant extracts.
