- 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.

“Not the story you wanted to hear": reading chick-lit in JM Coetzee’s Summertime

- Description: J.M. Coetzee’s Summertime has been widely explored – both for its controversy and merits – as engaging in “acts of genre” where the inscription of an autobiographical narrative simultaneously serves as a metatextual and ideological critique of its form. Similarly, this article is intrigued by generic instability, but our terrain lies further afield, exploring how the narrative lapses from the lofty ideals of romance to the baser “truth” of chick-lit. In Summertime, all the female characters besmirch Mr. Vincent, the biographer, for wanting to cast John Coetzee in the role of a romantic hero. Yet, their resistance results in a series of romantic failures which then situates Summertime in the generic ambit of chick-lit. In embodying a spirit that is as playful as it is critical, we suggest that Coetzee offers an opportunity to cast aside a literary critical tradition of suspicion and, in doing so, passes critical comment on how we approach a popular genre like chick-lit.

“A Step Towards Silence”: Samuel Beckett’s The Unnamable and the Problem of Following the Stranger

- Description: In this article, I argue that Samuel Beckett’s The Unnamable evinces the kind of aesthetic ambivalence that Theodor Adorno, in Aesthetic Theory, ascribes to the artwork’s location both in and outside of society. By tracing the metaphors used in the narrator’s depiction of the act of narration, I demonstrate that this novel self-reflexively articulates and meditates on its ambivalent position in society. Thereafter, I relate the work’s suspicion of its medium, and therefore its estrangement from itself, to its critique of community’s norms of recognition, which are embedded in language. Finally, I reflect on the potential effect of the text’s aesthetic ambivalence on the reader.

- Description: This article considers challenges posed to reading practices and hermeneutics by Ishtiyaq Shukri’s I See You. The content of the novel is at times didactic, and surface reading might seem an appropriate means of analysis, yet the form is experimental: it includes radio reports, characters’ reflections and journalistic work. The connection between these “documents” is not readily apparent, thus one is obliged to study the gaps between them to make sense of the text. Symptomatic reading might seem apposite, but the protagonist’s photographic work reveals the limits of this form of reading, too. I argue that Shukri’s text demands a process that interweaves symptomatic and surface reading in complex ways that require the reader to assess the ideological position from which s/he reads. The novel therefore draws attention to the ways in which reading, like seeing, is a political act.

- Description: This article, which focuses on African noir as a variety of neo-noir literature, begins by outlining the intertextual and intercultural relationships between classic noir and African noir. Thereafter, the postcolonial, postmodernist and transnational elements of African noir are described utilizing Mũkoma wa Ngũgĩ’s novel Black Star Nairobi (2013) and Leye Adenle’s When Trouble Sleeps (2018) as exemplars. Arguing that African noir draws on various genres and discourses, the article demonstrates how issues of socio-political justice, ontological and existential dilemmas, aesthetic concerns and the epistemological quest are rendered as ambiguous and murky. Based on a close reading of Black Star Nairobi and When Trouble Sleeps, the article concludes that the predominant chiaroscuro effect of African noir is not so much a ‘dark’ sensibility as one of abstruseness and poignant Afro-pessimism.

- Description: Ritual male circumcision is among the most secretive and sacred of rites practiced by the Xhosa of South Africa. Recently, the alarming rate of death and injury among initiates has led to the spotlight of media attention and government regulation being focused on traditional circumcision. While many of the physical components of the ritual have been little altered by the centuries, its cultural and social meanings have not remained unchanged. This paper attempts to understand how some of these cultural and social meanings have shifted, particularly with respect to attitudes towards sex and the role that circumcision schools traditionally played in the sexual.

They were advised that the granting of a permanent residence permit to the wife would only be considered upon payment of a hefty application fee, and that she had to apply for the permit from outside South Africa. The couple was of the view that the high cost of the application coupled with their temporary separation at the time of the lodging of the application amounted to an unjustifiable limitation of their right to family life. One of the obstacles faced by the couple was the silence of the South Africa Constitution on the right to family life.

- Description: There has been significant debate about the land occupations which occurred from the year 2000 in Zimbabwe, with a key controversy concerning the role of the state and ruling party (or party-state) in the occupations. This controversy, deriving from two grand narratives about the occupations, remains unresolved. A burgeoning literature exists on the Zimbabwean state’s fast-track land reform programme, which arose in the context of the occupations, but this literature is concerned mainly with post-occupation developments on fast-track farms. This article seeks to contribute to resolving the controversy surrounding the party-state and the land occupations by examining the occupations in the Shamva District of Mashonaland Central Province. The fieldwork for our Shamva study focused exclusively on the land occupations (and not on the fast-track farms) and was undertaken in May 2015. We conclude from our Shamva study that involvement by the party-state did not take on an institutionalised form but was of a personalised character entailing interventions by specific party and state actors.

- Description: Literature on the environmental Kuznets curve (EKC) is examined, focussing on the possibility that the EKC may be explained by trade patterns. If significant, this trade effect would cast doubt on the oft‐stated conclusion that economic growth automatically leads to environmental improvement. Research has been insufficient, although a number of promising approaches have been developed. Although evidence on the pollution‐haven hypothesis is mixed, there is enough to suggest that the EKC development path may not be available to today's developing countries. Other problems cast doubt on whether the EKC exists in any relevant sense at all.

It traces the judiciary’s stance on the separation of powers in the different stages of the litigation - before, during and after the conclusion of the legislative process. It does so against the background of South African precedent on the doctrine and in the light of a perceived power imbalance between the branches of government. Ultimately, it questions the appropriateness of the current understanding of the doctrine of separation of powers in the context of a dominant-party democracy.

The resultant compounds were evaluated in vitro for their potential activity against a cultured Trypanosoma brucei brucei 427 strain. Several compounds displayed mostly modest in vitro anti-trypanosomal activity with compounds 10e and 10h emerging as active candidates with IC50 values of 4.09 and 5.11 µM, respectively. More importantly, a concomitant assessment of their activity against a human cervix adenocarcinoma (HeLa) cell line revealed that these compounds are non-toxic.

- Description: Ratios between elements Mg, Fe, Co, Cr, Ni, V, and Sc are consistently different in mafic rocks of the upper critical zone, and those above the Bastard unit. Within the 300 m section above the Merensky Reef, 87Sr/86Sr ratios increase from c.0.7063 to c.0.7087, irrespective of rock type. Decoupling of Mg/(Mg + Fe2+) ratios and the Ca contents of plagioclase, and wide variations in the proportions of anorthosite within the Bastard, Merensky, and Merensky Footwall units, are inconsistent with anorthosite formation by simple fractional crystallization of magma batches of limited volume.

- Description: In South Africa, Carcharias taurus is commonly known as the ragged-tooth shark or raggie. The species is also referred to as the sand-tiger shark in North America and as the grey-nurse shark in Australia. It is a long-lived species with an estimated longevity of up to 40 years (Goldman 2002). Female sharks reach sexual maturity at approximately 10 years (Goldman 2002), and they exhibit a biennial reproductive cycle (Branstetter and Musick 1994, Lucifora et al. 2002, G Cliff, Natal Sharks Board, unpublished data). Intra-uterine cannibalisation results in a maximum fecundity of two pups per litter after a gestation period of approximately 9–12 months (Bass et al. 1975, Gilmore et al. 1983). These life-history characteristics make this species particularly susceptible to overexploitation.

- Description: Considerable research has been devoted to understanding and promoting parent-child sexual socialisation. Less attention has been paid to experiences of sibling interactions concerning sex. Drawing on discursive psychology, this study explores how women report interacting about sex and reproduction in their sisterly relationships. Ten in-depth interviews were conducted, using Free Association Narrative Interview technique, with five Black isiXhosa-speaking, middle-aged and working class women in South Africa.

- Description: Blocked-valley lakes are formed when tributaries are impounded by the relatively rapid aggradation of a large river and its floodplain. These features are common in the landscape, and have been identified in the floodplains of the Solimo˜es-Amazon (Brazil) and Fly-Strickland Rivers (Papua New Guinea), for example, but their inaccessibility has resulted in studies being limited to remotely sensed image analysis. This paper documents the sedimentology and geomorphic evolution of a blocked-valley lake, Lake Futululu on the Mfolozi River floodplain margin, in South Africa, while also offering a context for the formation of lakes and wetlands at tributary junctions. The study combines aerial photography, elevation data from orthophotographs and field survey, and longitudinal sedimentology determined from a series of cores, which were sub-sampled for organic content and particle size analysis. Radiocarbon dating was used to gauge the rate and timing of peat accumulation. Results indicate that following the last glacial maximum, rising sea-levels caused aggradation of the Mfolozi River floodplain. By 3980 years bp, aggradation on the floodplain had impounded the Futululu drainage line, creating conditions suitable for peat formation, which has since occurred at a constant average rate of 0Æ13 cm year)1. Continued aggradation on the Mfolozi River floodplain has raised the base level of the Futululu drainage line, resulting in a series of backstepping sedimentary facies with fluvially derived sand and silt episodically prograding over lacustrine peat deposits. Blocked-valley lakes form where the trunk river has a much larger sediment load and catchment than the tributary stream. Similarly, when the relative difference in sediment loads is less, palustrine wetlands, rather than lakes, may be the result. In contrast, where tributaries drain a steep, well-connected catchment, they may impound much larger trunk rivers, creating lakes or wetlands upstream.

- Description: Cancer and malaria remain relevant pathologies in modern medicinal chemistry endeavours. This is compounded by the threat of development of resistance to existing clinical drugs in use as first-line option for treatment of these diseases. To counter this threat, strategies such as drug repurposing and hybridization are constantly adapted in contemporary drug discovery for the expansion of the drug arsenal and generation of novel chemotypes with potential to avert or delay resistance. In the present study, a polymer precursor scaffold, 1,3-benzoxazine, has been repurposed by incorporation of an organometallic ferrocene unit to produce a novel class of compounds showing in vitro biological activity against breast cancer, malaria and trypanosomiasis.

- Description: While an interview could be described as a view among, between, betwixt, or in the midst of two subjects—from s'entrevoir (see each other); entre (between) and vue (view)—many interviews in art history are hierarchical not only in the sense of an interviewer “authoring” the material received from the respondent, but also in the sense of the theorist or writer shaping the ideas of the practitioner. As discussed in the First Word, “Situating Africa,” there is a tendency for writers in the “north” to theorize the professional practice of artists in the “south,” developing what Gordon Lewis (2006) refers to as a geography of reason. In their book Qualitative Interviewing: The Art of Hearing Data, Herbert J. Rubin and Irene S. Rubin (2012:7) develop the term “conversational partnership” to describe two or more participants who play an active role in shaping content as they cocreate meaning. This conversational partnership between two artists—one based in Uganda and the other based in South Africa—developed out of the publishing workshop at Rhodes University in June 2016, which aimed to approach the creation of knowledge from the perspective of “sideways learning” (see “Reaching Sideways, Writing Our Ways” in this issue). —Ruth Simbao.
