- Description: Advances in information and communication technologies are enabling higher educa-tion institutions to build virtual partnerships with other institutions. Virtual partner-ships are defined here as collaborations between geographically dispersed institutions, where interaction between these institutions is enabled mainly by electronic modes of communication. This article reports on the participants’ experiences of the implemen-tation of one such partnership from the perspective of a partner in a developing con-text. It uses the SANTED Virtual Classroom Project (VCP), a virtual partnership initia-tive between the Departments of Computer Science at the University of Namibia (UNAM) and Rhodes University (RU), as a case study. In the VCP, the department at RU was tasked with building teaching and human resource capacity in the department at UNAM. The article focuses on the challenges experienced at UNAM during the first year of implementation of the VCP and lessons learned.

- Description: The human soluble CD23 (sCD23) protein displays highly pleiotropic cytokine‐like activity. Monocytic cells express the sCD23‐binding integrins αVβ3, αVβ5, αMβ2 and αXβ2, but it is unclear which of these four integrins most acutely regulates sCD23‐driven cytokine release. The hypothesis that ligation of different sCD23‐binding integrins promoted release of distinct subsets of cytokines was tested. Lipopolysaccharide (LPS) and sCD23 promoted release of distinct groups of cytokines from the THP‐1 model cell line.

- Description: Organisms with different life-histories and abilities to disperse often utilise habitat patches in different ways. We investigated the influence of the size of patches of rock (separated by stretches of sand) on the density of pulmonate limpets (Siphonaria spp.) along 1500 km of the linear landscape of the South African coastline. We compared the influence of patch-size on two congeneric species with different modes of development, S. serrata a direct developer, and S. concinna a planktonic developer. We tested the spatial and temporal consistency of the effects of patch-size by sampling 7 independent regions spanning the distributional range of both species of limpets, and by sampling one region at monthly intervals for 1 year. Within each region or month, 4 small patches (<20 m in length) interspersed with the 4 large patches (>60 m in length) were sampled. Across the entire geographic range and throughout the year, there were more of both species of limpets in large patches than in small patches. In most regions, there was greater variability in large patches than small patches. Variability within patches in a single region was similar throughout the year, with greater variability of both species in large than in small patches. We found little influence of the mode of development on the response of limpets to patch-size. Our findings highlight the importance of understanding patterns of distribution of species with respect to habitat heterogeneity in linear landscapes, and contradict the idea that organism mobility at an early ontogenetic stage directly affects habitat use.

- Description: Recreational shore-based angling is one of the most popular sport and outdoor activity pastimes in South Africa with an estimated 412 000 fishers (McGrath et al. 1997). It is a form of linefishing where fish are caught using a hook and line and comprises a social as well as a more formal organized competitive sector (van der Elst 1989). Similar to other components of the linefishery, which include the subsistence as well as boat-based commercial sectors, excessive shore-fishing effort along the Eastern Cape has resulted not only in declining catches (Bennett 1991, Griffiths 1997, Brouwer and Buxton 2002, Pradervand and Govender 2003) but also changes in the species composition of catches (Bennett et al. 1994, Brouwer et al. 1997, Attwood and Farquhar 1999). Stock assessments indicate that many important linefish species are severely overexploited (Griffiths 1997, Hutchings 2000, Mann 2000) and that continued fishing pressure threatens endemic linefish populations. In 1996, shore-anglers alone were responsible for an annual catch of approximately 4.5 million fish, weighing around 3 000 tonnes (Brouwer et al. 1997).

The role of culture in enabling or constraining the use of technology in higher education teaching and learning: the Commerce Curriculum Project

- Description: This paper draws on a project located in one faculty at a South African university which aimed to use Information and Communication Technologies (ICTs) to enhance teaching and learning. More specifically, the paper uses Archer’s (1995, 1996, 2000, 1998) ‘analytical dualism’ and ‘morphogenesis’ to explore the way individuals involved in the project were able to exercise agency in departments which were relatively hostile to the goals they were aiming to pursue despite the wider cultural domain encompassing many ideas which construct the use of ICTs as significant in promoting student learning. The paper thus contributes to the culture/agency subtheme of the HECU6 conference. The paper begins by providing some background to the project before moving on to an exploration of the way Archer’s theoretical work was used to analyse data collected by project leaders.

Trauma, (Mis) Perception and Memory in Uwem Akpan's ‘Fattening for Gabon’:

- Description: It is a generally accepted principle in contemporary poststructuralist literary studies that language can only ever partially succeed in signifying that which it purports to signify. Where the profoundly dislocating experience of trauma is concerned, language loses even this partial success, and the victim of psychic violence is forced to resort to silence, a silence which is all the more expressive precisely because it overwhelms language. Thus, trauma fiction reveals what Steiner refers to as ‘the revaluation of silence’ which emphasises ‘the conceit of the word unspoken’ (67). Uwem Akpan's short story, ‘Fattening for Gabon’, from his collection Say You're One of Them (2008), is concerned with the culpability of socio-economic structures in giving rise to and perpetuating trauma in children. This paper will examine the retrospective narration of the protagonist by paying particular attention to the motif of memory. A discussion of the painful ambivalence of the experience and textualization of trauma, as conveyed through the story's use of silence and the disruption of the conventional bildung typical of narratives of remembrance, will form a substantial part of the paper.

- Description: Across the world, university teachers are increasingly being required to engage with diversity in the classes they teach. Using the data from a large Economics 1 class at a South African university, this attempts to understand the effects of diversity on chances of success and how assessment can impact on this. By demonstrating how theory can be used to understand results, the paper aims to encourage university teachers to adopt proactive strategies in managing diversity, rather than simply explaining it using student characteristics.
