  • Description: The avifauna of this forest reserve has been surveyed, based on observations and mist-netting over a ten-year period. We have recorded 175 species, of which 56 are considered" true" forest birds in this region. These include four summer migrants, and four occasional visitors; the others are likely to be resident. Four species of conservation concern, the Knysna Woodpecker, African Crowned Eagle, Lanner Falcon and Bush Blackcap probably nest within the protected area.

  • Description: The “privacy paradox” is the term used to describe the disconnect between self-reported privacy value attributions and actions actually taken to protect and preserve personal privacy. This phenomenon has been investigated in a number of domains and we extend the body of research with an investigation in the IoT domain. We presented participants with evidence of a specific IoT device’s (smart plug) privacy violations and then measured changes in privacy concerns and trust, as well as uptake of a range of behavioural responses. Our Saudi Arabian participants, despite expressing high levels of privacy concerns, generally chose not to respond to this evidence with preventative action.

  • Description: Academic developers are tasked with supporting institutions in times of change. Essential for preparing academic developers for professional practice is enabling them to engage with and integrate existing knowledge with new knowledge, and apply their understandings to new contexts. Focusing on the summative assessment processes and products of a course specifically for academic developers, this chapter shows how cumulative knowledge-building can be achieved in both course design and pedagogy. Drawing on LCT concepts of ‘semantic gravity’ and ‘semantic density’, two high-achieving portfolios were analysed. The analysis indicates that movements between knowledge that is relatively abstract, decontextualized and complex to knowledge that is relatively concrete, context-dependent and simpler, represents a key characteristic of cumulative learning for professional practice courses. The chapter demonstrates how LCT can reveal the tacit ‘rules’ for success in the course, as well as how pedagogic strategies can be designed to achieve the desired outcome.

  • Description: Asymmetric mono-carboxy-porphyrins, (5-(4-carboxyphenyl)−10,15,20-tris(pentafluorophenyl)porphyrinato zinc(II) (1), 5-(4-carboxyphenyl)−10,15,20-triphenylporphyrinato zinc(II) (2) and 5-(4-carboxyphenyl)−10,15,20-tris(2-thienyl)porphyrinato zinc(II) (3), were linked to Ag nanoparticles (AgNPs) through amide bonds and self-assembly (the latter only for 3). The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.

  • Description: In their official language policy, nearly all Sub-Saharan African states use their indigenous language(s) as Language of Learning and Teaching (LoLT) only at the beginning of primary schools. This is also the case in Malawi. The curricula in the various school subjects are also highly dominated by ‘Western’ ideas and include very little Indigenous Knowledge (IK). Nevertheless, indigenous languages are frequently used during lessons. This research focused on answering the following questions: How is a meaningful Science Education for pupils in Malawi possible? Does the inclusion of IK and teaching through African Languages assist pupils in any way? Research was done in the Northern Region of Malawi. To obtain a better understanding, semi-structured interviews and ethnographic observations were conducted. The main focus of these interviews was on the subject of ‘Agriculture’.

Using his words as the point of departure for a detailed investigation of a multi-stranded case of intertextuality, I examine the influence of McCarthy’s Blood Meridian on three South African novels – Mike Nicol’s Horseman, Damon Galgut’s The Quarry and James Whyle’s The Book of War – in a way that I hope sheds light on the provenance, literariness and meaning of these texts.

  • Description: IN PARENTHESIS is a practice-based essay which takes shape, parasitically, amidst the “found text” of an existing book, British author Thomas Pakenham's The Boer War (1979, Johannesburg: Jonathan Ball). The “author-reader” interjects into the found text of this authoritative history book, inserting her words amongst those of Pakenham's. What becomes apparent, however, is that the text into which she interjects is not The Boer War verbatim, but a dramatically abridged version. The book's primary content has been edited out. What remains is The Boer War whittled down to a litany of Pakenham's parentheses (the history book distilled into an essence of the seemingly non-essential). Into this stream of bracketed matter, the author-reader writes, ruminating on the parenthesis as ethos (as prison and portal, barricade and breach, enclave and embrace). In turn, her ruminations invite reflection on the conundrum of writing history, of writing this history (and, indeed, of writing per se).

  • Description: This chapter shares insights about green skills demand research in South Africa, based on a 2015 study in coal mining. One purpose of that study was to develop methodology for green skills demand determination, and the chapter shares selected features of the multi-layered and multi-method research process used, including an extended contextual driver analysis and a value chain analysis. Some findings about what green skills are needed in coal mining are shared to contextualise and illustrate methodological insights. This chapter highlights the fact that whether or not a skill is scarce can be contested, and demonstrates how a laminated methodology can guide credible conclusions in such cases. It also introduces the value of ‘absenting absences’, a dialectic process that surfaced skills needs that are not-yet-obvious, but essential if mining is to achieve transformation towards sustainability.

  • Description: Tourism generated through bonefish (Albula spp.) fishing contributes to the economies of many isolated tropical islands and atolls. However, little research has been conducted on bonefish in the Indian Ocean. This study aimed to contribute to the understanding of bonefish ecology in the Indian Ocean by quantifying the spatial and temporal movements of Albula glossodonta at a near-pristine and predator-rich atoll in the Seychelles; however, to achieve this, an analysis to identify the occurrence of possible post-release predation bias was first necessary. An acoustic telemetry study was initiated at the remote St. Joseph Atoll, within an array of 88 automated data-logging acoustic receivers. Thirty bonefish were surgically implanted with Vemco V13 acoustic transmitters and tracked for one year. Only 10% of the tagged bonefish were detected for longer than two weeks. A comparison of the final 100 h of movement data from fish detected for less than two weeks to the movement data of the fish detected for longer periods revealed distinct differences in area use and significant differences in the average daily distance moved, speed of movement and frequency of detections. This suggested that mortality in the form of post-release predation was at least 43% of tagged fish. The three surviving bonefish were tracked for 210 to 367 days. These individuals remained in the atoll and showed high use of the marginal habitats between the shallow sand flats and the lagoon. A generalised linear mixed model identified that water temperature, diel cycle and tide were significant predictors of bonefish presence in the lagoon. The high post-release mortality highlights that catch-and-release is likely not as benign as previously believed and management and policy should be adjusted accordingly.

  • Description: This paper examines the retelling of the story of Ethiopia in the Ethiopianist and pan-Africanist movements of the mid-nineteenth to mid-twentieth centuries. In this story, the trope of Ethiopia, which had been deployed in ancient history to signify Africa as racial other, is appropriated by Africans living on the continent and in the diaspora to signify the liberation of African people from both colonial rule and cultural alienation. Nevertheless, while Ethiopia is deployed as a trope of racial difference and race-based cultural aspirations, the demarcation it marks between self and other is indeterminate and ambiguous. This demarcation is unstable insofar as the trope of Ethiopia, and what it signifies in the world of the mid-nineteenth century to the mid-twentieth century, is defined not only by the cultural or religious meanings accrued over a period of almost thirty centuries, but also by the imperial politics of modern Ethiopia in the period under consideration. This politics crystallises around the coronation of Haile Selassie as emperor of Ethiopia in 1930, and marks both the culmination of the historical deployment of the Ethiopian trope and its moment of deconstruction.

  • Description: The global rollout of Antiretroviral Treatment (ART) has revealed an urgent need to understand the medicines-taking practices of HIV-positive adolescents. In the last decade, the literature on the social determinants of health has broadened the evidence-base on ART adherence. Interdisciplinary studies have expanded conceptions of medicines-taking beyond clinical or health systems frameworks, recognising the importance of socio-structural conditions and of patients’ beliefs and experiences. Participatory research techniques which foreground the perspectives of adolescents provide greater insights still into their adherence. This article explores the use of participatory methods within a broader study on the social determinants of ART adherence among HIV-positive adolescents in South Africa. We describe how participatory methods were incorporated into this study (n = 1,059 in the quantitative baseline). We focus on an exercise, ‘Yummy or crummy?’, that explored the multisensory dimensions of medicines-taking, including their colour, smell, shape, and delivery mechanism. We describe two principal findings: first, adolescents’ preference for greater understanding of the chemical workings of medicines, manifested in their preferences for colour, taste and shape of medicines; and second, the vital relationship between sensory preferences and the social imperatives of discretion and confidentiality regarding HIV-status.

  • Description: Higher education in post-apartheid South Africa has been concerned with the establishment of non-discriminatory institutions. However, research continues to highlight various experiences of exclusionary practices across universities in South Africa. In this article, we demonstrate the various coping mechanisms that some students who self-identify as gay, lesbian or bisexual in the university residences adopt to deal with the exclusionary practices that the dominant heteronormative culture of the institution (re)produces which positions them as “sexual strangers” within the institutional “home”. We adopt Vangelisti and Crumley’s (1998) three categories of behaviour namely “acquiescence” which we term here as endeavours to “fit in”, “invulnerability” which we identify as “keeping one’s distance”, “verbal active” as “voicing” and a fourth category we identify as “turning the tables on heteronormativity” in our discussion. We also highlight the various forms of responses that the institution adopts in its attempts to create a conducive environment for all.

  • Description: Brewery effluent (BE) needs to be treated before it can be released into the environment, reused or used in down-stream activities. This study demonstrated that anaerobic digestion (AD) followed by treatment in an integrated tertiary effluent treatment system transformed BE into a suitable solution for crop irrigation. Brewery effluent can be used to improve crop yields: Cabbage (Brassica oleracea cv. Star 3301), grew significantly larger when irrigated with post-AD, post-primary-facultative-pond (PFP) effluent, compared with those irrigated with post-constructed-wetland (CW) effluent or tap water only.

  • Description: Enterovirus 71 can be a severe pathogen in small children and immunocompromised adults. Virus uncoating is a critical step in the infection of the host cell; however, the mechanisms that control this process remain poorly understood. We applied normal mode analysis and perturbation response scanning to several complexes of the virus capsid and present a coarse-graining approach to analyze the full capsid. We show that our method offers an alternative to expressing the system as a set of rigid blocks and accounts for the interconnection between nodes within each subunit and protein interfaces across the capsid. In our coarse-grained approach, the modes associated with capsid expansion are captured in the first three nondegenerate modes and correspond to the changes observed in structural studies of the virus. We show that the resolution of the analysis may be modified without losing information on the global motions leading to uncoating.

  • Description: Quantitative measures of student performance fail to provide insight into underpinning constraints and enablements to access in science in higher education. This case study of a science foundation course uses Legitimation Code Theory as a theoretical frame and acquisition of recognition and realisation rules as an analytical frame to provide a depth empirical account of student access and success. Results indicate that access to the powerful science knowledge in the production (science) context is dependent on students recognising and realising the knower code of the learning context, which requires of them to be independent and autonomous learners. Such access is not afforded when students prior (school) learning-context relativist code clashes with the required university learning-context knower code. It is argued that a focus on the learning context could be key in enabling access to students whose educational background does not align well with that of the higher education context.

  • 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.

  • Identifier: http://hdl.handle.net/10962/157980 , vital:40136 , ISBN 978-1-137-55595-3
  • Description: Using the notion of “negative hermeneutics,” this chapter examines how Michiel Heyns’s novel Lost Ground draws on the heritage of the Sherlock Holmes stories. It argues that Heyns’s representation of contemporary South Africa necessitates a shift from the emphasis on the epistemological quests of nineteenth-century detective fiction to the “negative hermeneutics” and ontological concerns of postcolonial anti-detective fiction. An analysis of Lost Ground reveals direct intertextual and metatextual references to “The Silver Blaze,” yet the novel subversively presents a detective figure that is the antithesis of Holmes. Thus the chapter demonstrates how in postcolonial social and cultural contexts the ratiocinative process is hermeneutically inadequate and socio-political analysis comes to replace, or combine with, the feats of reason epitomized by Holmes.

  • Description: The Upper Zambezi, Kavango and Kwando are large floodplain rivers with substantial biodiversity, providing water and ecosystem services to a large tract of southern Africa. These rivers differ in hydrological regime. The Upper Zambezi and Kavango rivers are in flood for 4 months (March, April, May, June) while, in the Kwando River, floods are later and last for 1–2 months in July and August. The Upper Zambezi River has the largest annual flood pulse, followed by the Kavango River, while the Kwando River experiences small and unreliable floods. During years of exceptional flooding of the Upper Zambezi and Kavango rivers, the rivers are interconnected at peak flows and therefore share a common ichthyofauna. This provided a natural experiment to investigate the responses of fish communities comprised of the same species to differing flood regimes by comparing the fish assemblages and food‐web structures between rivers.
