- Description: This paper focuses on the Southern African Association for Research in Mathematics, Science and Technology Education’s (SAARMSTE’s) role as a platform supporting research dissemination and connecting researchers in early grades mathematics (EGM) in the Southern African region. A review of the Long Papers in SAARMSTE over the last 20 years supports the finding of the other review papers in this Special Issue: that there has been substantial growth of attention to EGM since 2013. However, two distinctions are marked when looking at conference papers rather than journal papers. Firstly, there is a particularly large expansion of work in the last 5 years, with a broadening base of participation in this work. Second, looking across all the formats of conference presentations indicates SAARMSTE’s role in supporting and building EGM as a key focus of research attention, and bringing together regional and international groups with interests in this area. Given that conference proceedings usually offer a broader picture of emerging interests than journal papers, we reflect on the range of foci of attention within EGM in the SAARMSTE Proceedings, and trends within this. These trends also help us to point to areas that are likely to be of key interest in the next decade.

- Description: Sign language recognition is an evolving research field in computer vision, assisting communication between hearing disabled people. Hand gestures contain the majority of the information when signing. Focusing on feature extraction methods to obtain the information stored in hand data in sign language recognition may improve classification accuracy. Pose estimation is a popular method for extracting body and hand landmarks. We implement and compare different feature extraction and segmentation algorithms, focusing on the hands only on the LSA64 dataset. To extract hand landmark coordinates, MediaPipe Holistic is implemented on the sign images. Classification is performed using poplar CNN architectures, namely ResNet and a Pruned VGG network. A separate 1D-CNN is utilised to classify hand landmark coordinates extracted using MediaPipe. The best performance was achieved on the unprocessed raw images using a Pruned VGG network with an accuracy of 95.50%. However, the more computationally efficient model using the hand landmark data and 1D-CNN for classification achieved an accuracy of 94.91%.

- Description: Trachinotus botla is an important recreational surf zone-dependent fish species distributed in the Indo-west Pacific from South Africa to Australia. In South Africa it is restricted to the northern KwaZulu-Natal coast. Biological investigations revealed that it is a fast growing species that attains a maximum age of, 7 years. Males and females sexually matured in their third year. It has a protracted summer spawning season with evidence of serial spawning behaviour. T. botla is an opportunistic predator with a generalist diet, with fish feeding on a wide variety of prey items particularly those that are temporally ‘superabundant’. Small fish fed predominantly on copepods and terrestrial insects, whereas larger fish consumed bivalves and crabs. Teleosts, primarily engraulids, were important components to the diet of fish of all sizes. An ontogenetic dietary shift was observed just after sexual maturity (300-mm fork length) that is possibly linked to a change in habitat preference with larger fish foraging on deeper reefs.

- Description: Surf-zone fish communities and their shifts over time are generally poorly understood. The aim of this study was to compare the current surf-zone fish assemblage at King’s Beach, South Africa, to a similar study conducted three decades ago, before the collapse of many exploited shore fishes in the region. Beach seine nets (mesh sizes of 10 and 50 mm) were used to target juvenile and adult fishes bimonthly from February to August 2011 over the high tide around sunset. A total of 14 species were recorded in both the 30mand 100mseine nets. The catch in these seine nets was dominated by Pomadasys olivaceus and Liza richardsonii, and this was significantly different to three decades ago, when P. olivaceus, Sarpa salpa and Diplodus capensis dominated the catch. Important linefish species belonging to the Sparidae and Sciaenidae families were significantly smaller and less abundant in this study. Two sparids, S. salpa and Lithognathus mormyrus, which made a large contribution to the surf-zone catch three decades ago were absent during this study. Reasons for the significant shifts in the surf-zone fish community, including overexploitation of the linefish and potential habitat modification, are discussed.

- Description: We examined how human harvesting impacts on managed areas affect the abundance and size distribution of the edible mangrove shellfish Anadara granosa and Polymesoda spp. in the Roviana Lagoon, Solomon Islands. We tested two hypotheses: (1) in areas permanently and temporally closed to human exploitation, abundance and size distribution of these shellfish species is significantly greater than in sites open to exploitation and (2) moderate human disturbance of shell beds, particularly of Polymesoda spp., increases their abundance. Firstly, we studied perceptions of environmental states and processes coupled to foraging and management interventions to assess sociocultural influences on harvesting practices and ascertain the types of management regime that people would consider in a context where poaching and interloping are common practices. Secondly, we compared shellfish abundance and shell size from areas that were permanently protected, temporally reserved for communal harvest, and permanently open for exploitation. Thirdly, drawing from women’s local knowledge, we measured the abundance of Polymesoda spp. in relation to mud compactness in quadrats across the three management regimes. Results showed that both species were significantly more abundant in permanent and temporally closed sites than in open sites. In the mud compactness study, however, while shell abundance was greater in moderately compacted quadrats, there was no statistical relationship between mud compactness and shell abundance within or across the three management regimes. Results suggest that even under the strong impacts of poaching, temporally closed areas have more clams than open areas and are as effective as areas that are permanently closed nominally. The results also suggest that human harvesting regimes can influence the effectiveness of local management decisions and thus are important when designing community-based conservation programs in the Solomon Islands and other Pacific Islands.

- Description: The shore of Lake St Lucia in the vicinity of Catalina Bay, in the southern part of the lake, receives freshwater input as surface and groundwater seepage from the adjacent elevated coastal plain. Vegetation, water quality and landform were recorded on the lakeshore and on the dry lakebed near one of these seepage zones. This was done along a gradient perpendicular to the lakeshore and along the lakeshore away from the fluvial source of freshwater input. A number of plant communities were found along a gradient of water salinity from the shoreline (fresh water) towards the centre of the lake, and also away from the fluvial input of water (increasingly saline). Species richness decreased with increasing salinity. The first study was conducted in 2006 after a prolonged drought associated with low lake levels and closure of the mouth, and repeated again in 2010 three years after breaching of the estuarine mouth by a tropical cyclone at sea, which caused inundation of the partly dry lakebed with sea water. The vegetation of the lakeshore after these major disturbances was remarkably similar in the two time periods, suggesting rapid recovery near freshwater seepage zones, following an influx of sea water.

- Description: The Benguela Cold Current system, located in the south-eastern Atlantic, features cold sea surface temperatures, bounded to the north and south by tropical currents (the Angola and Agulhas Currents, respectively) and a perennial upwelling cell off central Namibia that divides the region into two sub-systems with different characteristics (Shannon 1985; Hutchings et al. 2009). The colder sea surface temperatures of the Benguela Current have been considered an important biogeographic barrier, isolating tropical and warm-temperate fauna of the Atlantic and Indo-Pacific Oceans (Avise 2000; Floeter et al. 2008). However, recent studies revealed that other oceanographic features, such as the perennial upwelling cell, may also play an important role in shaping the population structure of warm temperate fish populations within the Benguela system, as complete disruption of gene flow was documented both in Lichia amia (Linnaeus, 1758) and Atractoscion aequidens (Cuvier, 1830) (Henriques et al. 2012, 2014). Little is known, however, regarding the influence of the Benguela system on genetic population connectivity of cold-water-tolerant species.

- Description: Based on a survey of 4,393 journalism students in Australia, Brazil, Chile, Mexico, South Africa, Spain, Switzerland, and the United States, this study provides much-needed comparative evidence about students’ motivations for becoming journalists, their future job plans, and expectations. Findings show not only an almost universal decline in students’ desire to work in journalism by the end of their program but also important national differences in terms of the journalistic fields in which they want to work, as well as their job expectations. The results reinforce the need to take into account national contexts when examining journalism education across the globe.

- Description: Tourism is a significant driver of social and ecological change in developing countries, particularly in small-island states, which are susceptible to tourism impacts due to their particular social and environmental characteristics. In this article we present a participatory mapping approach to obtaining spatially explicit local perceptions of future environmental and social change resulting from tourism development, as well as addressing the different community conflicts that may arise through the introduction of tourism in the future in a Solomon Islands community. The results show that spatial conflicts within a community over territory and associated resources are likely to occur when designing natural resource management and tourism development plans. This knowledge can help us increase the future sustainability of tourism in nascent small-islands destinations, particularly in vulnerable regions such as Roviana, which have experienced very little tourism development and will likely experience more in the near future.

- Description: The heat shock organizing protein (Hop) is important in modulating the activity and co-interaction of two chaperones: heat shock protein 70 and 90 (Hsp70 and Hsp90). Recent research suggested that Plasmodium falciparum Hop (PfHop), PfHsp70 and PfHsp90 form a complex in the trophozoite infective stage. However, there has been little computational research on the malarial Hop protein in complex with other malarial Hsps. Using in silico characterization of the protein, this work showed that individual domains of Hop are evolving at different rates within the protein. Differences between human Hop (HsHop) and PfHop were identified by motif analysis. Homology modeling of PfHop and HsHop in complex with their own cytosolic Hsp90 and Hsp70 C-terminal peptide partners indicated excellent conservation of the Hop concave TPR sites bound to the C-terminal motifs of partner proteins. Further, we analyzed additional binding sites between Hop and Hsp90, and showed, for the first time, that they are distinctly less conserved between human and malaria parasite. These sites are located on the convex surface of Hop TPR2, and involved in interactions with the Hsp90 middle domain. Since the convex sites are less conserved than the concave sites, it makes their potential for malarial inhibitor design extremely attractive (as opposed to the concave sites which have been the focus of previous efforts).

- Description: The exhibition catalogue Rise and Fall of Apartheid is a valuable collection of photographic images that create, according to Enwezor, “a critical visualization and interrogation of […] [apartheid’s] normative symbols, signs and representation” (18). The catalogue focuses on African subjects as “agents of their own emancipation” (18), and contextualises South Africa’s anticipation of the end of apartheid within broader global changes in the late 1980s. Essays by Okwui Enwezor, Michael Godby, Achille Mbembe, Darren Newbury, Colin Richards, Patricia Hayes, Andries Walter Olifant, Rory Bester and Khwezi Gule are included in the catalogue, and are interspersed between photographic images that are grouped in chronological clusters: 1948–1959; 1960–1969; 1970–1979; 1980–1989; and 1990–1995.

- Description: This paper explores the challenges faced by small municipalities in providing water services in a developing world context of increasing urban demand. The paper uses a case study of the Sundays River Valley Municipality (SRVM) in South Africa. The municipality faces multiple dilemmas in reconciling its available water supply with growing demand for potable water in the primary urban settlement in the area, in a struggle that is typical of the broad category of South African municipalities to which the SRVM belongs. These dilemmas are explored using a system dynamics model, referred to as the ‘Kirkwood water demand system dynamics model’ (K-DEM). This paper specifically introduces the K-DEM structure,which is aimed at investigating the impacts of households progressively receiving full water and sanitation services; the use of rainwater harvesting as an alternative form of water supply; and the possible effect of a household-level water conservation / water demand management programme. Baseline results are discussed, and areas for future research identified.

"I felt that I deserved it" : an Investigation into HIV-related PTSD, traumatic life events, and the personal experiences of living with HIV : a mixed-method study

- Description: There appears to be a growing body of literature focusing on PTSD and HIV-related PTSD (the diagnosis of HIV being the significant traumatic event) amongst HIV-positive samples, but only a few African studies that attempt to estimate the prevalence of PTSD amongst HIV-positive people, and even fewer that attempt to estimate the prevalence of HIV-related PTSD. The systemic review presented in this study is currently fully inclusive and is the most up-to-date available. Estimates of the prevalence of PTSD and HIV-related PTSD in South Africa range from 0.7 to 54.1% and, 4.2 to 40% respectively. The current cross-sectional study made use of a mixed-method approach to investigate traumatic life events, PTSD and HIV-related PTSD within a primary health-care centre in KwaZulu-Natal. The quantitative sample consisted of 159 adults (18-50 years) who were compliant on ARV medication. Using the CIDI-PTSD module, the adapted CIDI-PTSD module for HIV, and IES-R, findings indicated that 62% had reported some kind of traumatic event in their lifetime, with 29.6% of participants meeting the criteria for lifetime PTSD, and 40.9% meeting the criteria for lifetime HIV-related PTSD. Altogether, 57.9% of individuals met the criteria for some form of PTSD (either regular PTSD or HIV-related PTSD), and 12.6% met the criteria for both PTSD and HIV-related PTSD. Of the different categories of traumatic events, interpersonal violence has the highest rate of PTSD, followed by a diagnosis of and living with HIV, and then disaster. Furthermore, the IES-R was compared for its usefulness as a screening measure for PTSD against both the CIDI, but results suggest that it is an inferior screening measure to the PDS. The qualitative study consisted of six participants who were examined using IPA methodology informed by the Ehlers and Clark (2000) Model of trauma. Their experiences revealed experiences of stigma, a number of negative appraisals, negative emotions and coping behaviours. Some of the latter might serve as compensatory mechanisms to avoid negative judgements. Hypervigilance seems to be a feature of ARV-compliance that might confer added vulnerability to PTSD and other anxiety disorders.

"To learn how to speak": a study of Jeremy Cronin's poetry

- Description: In the chapters that follow, the porous boundary between the public and the private in Jeremy Cronin’s poetry is investigated in his three collections, Inside (1983), Even the Dead: Poems, Parables and a Jeremiad (1996) and More Than a Casual Contact (2006). I argue two particular Marxist theorists are central to reading Cronin’s poetry: Bertolt Brecht, and his notion of the Verfremdungseffekt, and Walter Benjamin and his work on historical materialism, primarily the essay On the Concept of History / Theses on the Philosophy of History (1940). Both theorists focus on the work of art in a historically contextualized manner, which extends the challenge to the boundary between the public and the private. Their work is underpinned by the desire to draw out hidden narratives occluded under the grand narratives of history and capitalist ideas of progress. I argue that these are the major preoccupations in Cronin’s oeuvre as well. As such Cronin’s poetry may be seen to write against a perspective that proposes a linear conceptualisation of history. The poetry therefore challenges the notion that art speaks of ‘universal truths.’ Such ideas of History and Truth, if viewed uncritically, allow for a tendency to conceive of the past as unchanging, which subconsciously promotes the idea that social and political realities are merely logical evolutionary steps. I argue that Cronin’s poetry is thus purposefully interruptive in the way that it confronts the damaging consequences of the linear conceptualisation of history and the universal truth it promotes. His work attempts to find new ways of connection and expression through learning from South Africa’s violent past. The significance of understanding each other and the historical environment as opposed to imposing perspectives that underwrite the symbolic order requires the transformation rather than the simple transferral of power, and is a central focus throughout Cronin’s oeuvre. This position suggests that while the struggle for political freedom may be over, the necessity to rethink how South Africans relate to each other is only beginning. Chapter One will focus on positioning Cronin, the poet and public figure, in South African literature and literary criticism. In this regard, two general trends have operated as critical paradigms in the study of South African poetry, namely Formalism (or ‘prac crit’) and a Marxist inflected materialism, which have in many ways perpetuated the division between the private and the public. This has resulted in poetry being read with an exclusive focus on either one of these two aspects, overlooking the possibilities of dialogue that may take place between them. Cronin’s perspective on these polarised responses will be discussed, which will illustrate the similarity of his position to Ndebele’s notion of the ‘ordinary’ which suggests a way beyond these binaries. This will lead to a discussion of how South African poets responded to the transition phase, suggesting that the elements of the polarisation still remained. Considering the major influences and paradigms when reading Cronin’s oeuvre provides a foundation for the following three chapters. These include Cronin’s use of Romanticism, Bertolt Brecht and the V-Effekt and Walter Benjamin’s perspectives on historical materialism. In addition to these three theoretical paradigms, the relevance of Pablo Neruda’s poetry to Cronin’s work is also foregrounded. In Chapter Two, the focus will be on Cronin’s first collection of poetry, Inside, concentrating on Cronin’s use of language as a way of constructing poetry in the sparseness of the prison experience. This will show an abiding preoccupation of learning to speak in a language that considers the material context out of which it emerges. In this regard, the poems “Poem-Shrike” “Prologue” and “Cave-site” are analysed. In addition, one of the central poems in Cronin’s oeuvre, “To learn how to speak […],” will be examined in order to illustrate how the poet extends this project on a meta-poetic level, asking for South African poets to ‘learn how to speak’ in the voices of South African experience and histories. I will show how this is linked to Cronin’s “Walking on Air” which illustrates how the V-Effeckt recovers the small private histories through re-telling the life story of James Matthews, a fellow prisoner incarcerated for his anti-apartheid activism, revealing how this story is intimately connected to the public sphere. In Chapter Three, Cronin’s second collection: Even the Dead: Poems, Parables and a Jeremiad will be examined. In the poem “Three Reasons for a Mixed, Umrabulo, Round-the-Corner Poetry” Cronin resists inherited Western poetic conventions by incorporating and subverting versions of the Romantic aesthetic, arguing for poetry to be immersed in South African multi-lingual and multi-cultural experiences. “Even the Dead” reveals how Cronin uses Walter Benjamin’s perspectives on historical materialism to confront amnesia. In terms of the themes established in “To learn how to speak […]”, the poem “Moorage” demonstrates how the public and private can never be separated in Cronin’s work. The final section of this chapter will examine how Cronin responds to Pablo Neruda’s poems “I am explaining a few things” and “The Education of a Chieftain,” and how these poems challenge narratives that privilege the ‘great leader’ instead of the so-called smaller individuals’ stories. Chapter Four examines selections from Cronin’s third collection, focusing on Cronin’s use of the automobile, charting an ambiguous trajectory through the ‘new’ South Africa. The examination of the poems “Where to begin?”, “Switchback” and “End of the century - which is why wipers,” all attempt to include individuals left on the margins of the narrative of global freeways and neo-liberal capitalist progress. The poems present an interrogation of how ‘vision’ is constructed. This will show that the poetry responds to the experiences of the marginalised under these grand narratives in a primarily fragmentary and interruptive manner. This in effect constitutes the culmination of Cronin’s poetic journey and the search for new ways of envisaging South Africa’s future and finding a new language with which to speak it.

- Description: The 1996 Constitution of South Africa is ranked as one of the most liberal and democratic constitutions in the world. The right to freedom of sexual orientation, equality and the freedom of association amongst other rights is in its Bill of Rights and are thus inherently assured and protected in post- apartheid, democratic South Africa. However, the Lesbian Gay Bisexual and Transgender (LGBT) community continue to face discrimination and prejudice despite this newly established constitutional order. The present study is interested in how, in the light of the equality clause in the South African constitution, homosexuality is represented and constructed in the South African media. The thesis examines representations of homosexuality between the years 1999-2013 in articles collected from the Independent Online media site which incorporates 30 newspapers. The approach focuses on the topics, overall news report schemata, local meanings, style and rhetoric of the news reports. The results of the study show that negative attitudes towards homosexuality are framed in three main ways: homosexuality is represented as "unAfrican"; "ungodly" and "unnatural". I argue that rather than extreme forms of violence (such as "corrective rape" and murder) directed against LGBT citizens being interpreted as the aberrant behaviour of a few, these need to be understood in the context of the circulation of the above justificatory narratives.

- Description: At present the Swedish points system is one of the main determinants of an applicant either being granted or refused entry into many South African higher education institutions (HEIs). Using a grounded theory approach, this article interprets the experiences of participants whose school performance and therefore university 'entry points' were lower than the expected norm. Despite not meeting standard university entry requirements, these students succeeded at university, completing their degrees in the minimum time available and going on to higher degrees. The journey of these participants - from low entry points to academic success - suggests that points based on school performance are not necessarily the best way of identifying students' potential to succeed in the contemporary South African educational context. If their entry points were not a good indication of their ability to thrive at university, the article asks, what is it about these participants that accounts for their success? And what implications does this have for South African practice, not only with regard to admissions policies but also in relation to the responsibilities of HEIs to students once they are admitted?

- Description: Gibson Ncube’s ‘Sexual/Textual Politics: Rethinking gender and sexuality in gay Moroccan literature’ focuses on an emerging body of gay literature that is developing within the larger framework of Moroccan literature. Ncube attempts to illustrate how the contemporary narratives of Rachid O. and Abdellah Taïa portray the quotidian experiences of minority sexualities who strive to exist in the hegemonic heteropatriarchies of Moroccan societies. These narratives challenge and destabilise the heteronormative ideals of Arab-Muslim communities and endeavour to offer alternative ways of thinking about marginalised sexualities in the public space. This analysis draws on the feminist underpinnings of Maria Pia Lara to argue that private gay narratives have the potential to re-imagine the public domain.

The UNDESD was born in Johannesburg in 2002; it was an outcome of the Johannesburg Implementation Plan formulated by world leaders at the World Summit on Sustaina-ble Development, hosted by the South African government, building on the earlier Rio Earth Summit. Nelson Rolihlahla Mandela attended the opening of the World Summit on Sus-tainable Development soon after he left office as the first dem-ocratically elected President of the Republic of South Africa. He passed away a week ago today, on 5 December 2013, at the age of 95. His life story is well known. I write here about his words ‘We must start with our own children’.

- Description: This paper was prepared today, 13 December 2013, for this book on ‘Intergenerational learning and transformative leader-ship for sustainable futures’, to be released in November 2014 at a World Conference to mark the end of the UN Decade of Education for Sustainable Development (UN-DESD) in Nago-ya, Japan. The UNDESD was born in Johannesburg in 2002; it was an outcome of the Johannesburg Implementation Plan formulated by world leaders at the World Summit on Sustaina-ble Development, hosted by the South African government, building on the earlier Rio Earth Summit. Nelson Rolihlahla Mandela attended the opening of the World Summit on Sus-tainable Development soon after he left office as the first dem-ocratically elected President of the Republic of South Africa. He passed away a week ago today, on 5 December 2013, at the age of 95. His life story is well known. I write here about his words ‘We must start with our own children’.

- Description: Deon van der Walt was, at the height of his career, considered the leading lyric tenor of his generation. In a career that spanned more than 25 years he performed in the great opera houses of the world and sang for the leading conductors of the time, sharing the stage with the best singers in the world. He was the first male South African to accomplish the so-called “grand slam” of opera, having sung in the Royal Opera House, Covent Garden (London), Wiener Staatsoper (Vienna), La Scala (Milan) and the Metropolitan Opera House (New York). He was also a prolific oratorio and lieder singer, collaborating with the best artists the musical world had to offer. In addition he left a large recorded legacy, both published and unpublished. His untimely death on 29 November 2005 was extensively reported on both locally and abroad - a fact which again highlighted the importance of his personal and professional contribution to the international opera world.The Deon van der Walt Collection is the single most important key to unlocking the life and career of one of the most successful South African opera singers of all time. It was bequeathed to the Nelson Mandela Metropolitan University (NMMU) Library the Deon van der Walt Trust in 2007. The collection is made up of an arbitrary assortment of books, documents, sound and video recordings that were left in van der Walt’s Zürich accommodations at the time of his death in 2005. It is housed in separate section on the lower level of the South Campus Library of the NMMU. The collection has been partially catalogued by the NMMU Library but left largely unattended for the last 6 years. The compiling of an annotated catalogue of this collection is the vital first step in connecting the dots of an extraordinary musical career that was hailed as one of the greatest of his time.

(Re-)inventing our selves/ourselves : identity and community in contemporary South African short fiction cycles.
- Authors: Marais, Susan Jacqueline
- Date: 2014
- Subjects: South African fiction (English) -- History and criticism , Matlou, Joël -- Criticism and interpretation , Magona, Sindiwe -- Criticism and interpretation , Vladislavić, Ivan, 1957- -- Criticism and interpretation , Wicomb, Zoë -- Criticism and interpretation

- Description: In this study I focus on a number of collections of short fiction by the South African writers Joël Matlou, Sindiwe Magona, Zoë Wicomb and Ivan Vladislavić, all of which evince certain of the characteristics of short story cycles or sequences. In other words, they display what Forrest L. Ingram describes as “a double tendency of asserting the individuality of [their] components on the one hand and of highlighting, on the other, the bonds of unity which make the many into a single whole”. The cycle form, thus defined, is characterised by a paradoxical yet productive and frequently unresolved tension between “the individuality of each of the stories and the necessities of the larger unit”, between “the one and the many”, and between cohesion and fragmentation. It is this “dynamic structure of connection and disconnection” which singularly equips the genre to represent the interrelationship of singular and collective identities, or the “coherent multiplicity of community”. Ingram, for example, asserts that “Numerous and varied connective strands draw the co-protagonists of any story cycle into a single community. … However this community may be achieved, it usually can be said to constitute the central character of a cycle”. Not unsurprisingly, then, in its dominant manifestations over much of the twentieth century the short story cycle demonstrated a marked inclination towards regionalism and the depiction of localised enclaves, and this tendency towards “place-based short story cycles” in which topographical unity is a conspicuous feature was as pronounced in South Africa as elsewhere. However, the specific collections which are my concern here increasingly employ innovative and self-reflexive narrative strategies that unsettle generic expectations and interrogate the notions of regionalism and community conventionally associated with the short story cycle. My investigation seeks to explain this shift in emphasis, and its particular significance within the South African context.
