- Description: Doreen Baingana’s Tropical Fish explores the migratory experiences of the main narrator-focalizer, Christine Mugisha, as she travels from Uganda to the United States of America. Although the analyses of home, exile, and migration by writers like Edward Said and Paul Tiyambe Zeleza tend to be ungendered; Baingana seems to elaborate on these concerns by reflecting on the gendered experience of travel. As Carole Boyce Davies has argued, the act of travelling and migration opens up new spaces and possibilities for black women writers as they come into contact with multiple places and cultures. In their encounters with migration, black women are able to negotiate and re-negotiate their identities. This article focuses on how Tropical Fish, interrogates complex, contradictory, ambiguous and often conflicted questions of home and migration with their concomitant issues of belonging and alienation/ estrangement and how they are intimately tied to the maternal bond.

- Description: Using the concept of ‘competitive authoritarianism’, this briefing examines how the governing Zimbabwe African National Union – Patriotic Front (ZANU–PF) retained power in the July 2018 presidential, parliamentary and local government elections. It advances that, having come to power through military assistance in November 2017, the new ZANU–PF government instituted cosmetic political reforms to gain domestic and international legitimacy while maintaining financial networks and tentacles on public institutions. This briefing posits that, with a huge funding base, abuse of public resources and massive vote buying, materially, Zimbabwe's 2018 elections were heavily slanted in favour of ZANU–PF.

- Description: The year 1999 is the year of assessing performance and delivery. In the political arena we are reflecting on the accomplishments and shortcomings of our young democracy as we prepare our nation for South Africa's second democratic elections on the 2nd of June 1999. At this time, it is important that we also evaluate the progress we as a united labour movement made subsequent to April 1994, since the involvement of COSATU in our struggle for democracy was and still remains crucial. For women the 2nd of June 1999 presents itself as a challenge, especially women within COSATU. The challenge lies in the need to ensure that women are more represented in all structures of the federation, affiliates, down to local structures. Women make up the majority of citizens in South Africa and have been and remain under represented within the trade union movement. This has been the case since the launch of COSATU in 1985.

- Description: Student activists in South Africa have put the decolonisation of higher education firmly on the agenda, demanding that researchers and teachers pay attention to something in particular that is very hard to hear and very possibly unhearable. These young, black South Africans are the intellectual force upon whom we are depending for the altered future of our country. We cannot change the circumstances which continue to frustrate and anger them without paying particular attention to them. Taking on the knowledge bases and knowledge generation in the Global South, they are demanding that we rethink the logos-based project of universities in South Africa. Their struggle is critically about how knowledge is implicated as a shaping force in lives which are still defined by colonial governmentality.

- Description: The demand for “methodologies of education and learning” is very significant in the current FeesMustFall discourse. This is not just because it is necessary to consider education methodologies, but in the broader scheme of things, it is also a call to both mental and ideological transformation. It challenges university lecturers and educators alike to question their own preconceived pedagogies and engage in an introspection - a 2 reflective moment in their teaching. I will come back to this later in my presentation. The point I am trying to emphasis is that the call for “The-Fall-in-Fees” is a development issue. It is a development issue because it gravitates around access to [Higher] education. We just need to remind ourselves by what Nelson Mandela once said: “Education is the most powerful weapon which you can use to change the world”. We all know-education is a fundamental human right; so too is development (United Nations, 1986). The denial to education is an act of injustice. But like Martin Luther King Jr. said: “Injustice anywhere is a threat to justice everywhere” (Luther King Jr, 1963). In this regard, there is a lot of development injustice to which my lecture this evening alludes to.

- Description: This paper highlights the methodology that has been used at Rhodes University and other South African universities in implementing vocation-specific African language learning programmes. Essentially, the paper links the curriculum design to the theoretical paradigm of intercultural communication. Intercultural theory is used as a basis to develop vocation-specific courses where language and culture are taught, for example, to second language learners of isiXhosa at Rhodes University. These courses include courses for Pharmacy and Law students. This paper offers a new theoretical paradigm for intercultural language teaching. Furthermore, examples from specific courses are provided in order to illustrate how this theoretical paradigm can be implemented in a practical way. The impact of multilingualism and intercultural communication in the wider legal and healthcare work environment in South Africa is also discussed.

- Description: Community-based approaches are pursued in recognition of the need for place-based responses to environmental change that integrate local understandings of risk and vulnerability. Yet the potential for fair adaptation is intimately linked to how variations in perceptions of environmental change and risk are treated. There is, however, little empirical evidence of the extent and nature of variations in risk perception in and between multiple community settings. Here, we rely on data from 231 semi-structured interviews conducted in nine communities in Western Province, Solomon Islands, to statistically model different perceptions of risk and change within and between communities.

- Description: In many universities, economics teachers now face the challenge of dealing with large, diverse classes, especially at undergraduate level. A common concern is the non-attendance at lectures of unmotivated (conscript) students. This paper presents the results of a student assessment of a macroeconomics 1 course, coupled with a self-assessment of their own input into the course. The results obtained, using an econometric model, suggest that what students do outside of lectures is equally, or more, important than lecture attendance itself. The paper concludes by examining the possibility of using peer assessed group learning as a feasible way to encourage deep learning in large classes.

- Description: The idea to restructure the union is not a new one. Political changes in our country compelled almost all the unions to consider the possibilities of restructuring the union and the industry in general. New approaches to Collective Bargaining Strategies came to the fore. The good example of these Bargaining strategies was the NUMSA THREE YEAR BARGAINING STRATEGY (1993). Later in the same year, CWIU also introduced its Bargaining Strategy in the form of five pillars. The common thing about Numsa and CWIU bargaining strategies is that they both failed to deliver and the process of setting up working groups are more complex than expected. The main cause of the tap problem in my view is that the existing union structures are a big deterent to the development and implementation of new bargaining strategies. Our Centralised Bargaining victory and the new LRA will demand major union restructuring if we want to utilise the openings created by these new developments. In this discussion paper, I will focus on how we should restructure our union. In this paper, I am suggesting that the union (CWIU) must be made up of four semi-autonomous departments.

The income from subscriptions was forever fluctuating. In most cases expenditure for this period exceeded the income from subscriptions. Our bank balance was, from time to time, in an overdraft situation. The union couldn’t be self-sufficient—and as a result, relied on foreign funding.

- Description: We investigated the relative importance of dispersal and vicariance in forming the Madagascar insect fauna, sequencing approximately 2300bp from three rRNA gene regions to investigate the phylogeny of Afrotropical small minnow mayflies (Ephemeroptera: Baetidae). Six lineages contained trans-oceanic sister taxa, and variation in genetic divergence between sister taxa revealed relationships that range from very recent dispersal to ancient vicariance. Dispersal was most recent and frequent in species that spend the larval stage in standing water, adding to evidence that these evolutionarily unstable habitats may select for ecological traits that increase dispersal in insects. Ancestral state likelihood analysis suggested at least one Afrotropical lineage had its origin in Madagascar, demonstrating that unidirectional dispersal from a continental source may be too simplistic. We conclude that the Malagasy mayfly fauna should be considered in a biogeographical context that extends beyond Madagascar itself, encompassing trans-oceanic dispersal within multiple lineages.

- Description: The relationships between the spatial distribution of gully erosion and topographic thresholds in the form of slope angle, position and configuration, as well as land use change in the form of abandoned lands were examined in several affected catchments of the Eastern Cape Province, South Africa. Land use and permanent gullies were mapped, digitized from orthophoto maps in Arc/info 3.5.2 GIS and converted to shapefiles using ArcView 3.2 GIS. Relationships between the mapped phenomena and topographic variables were sought using a Digital Elevation Model (DEM) in Idrisi Kilimanjaro GIS. A comparison between areas with a high potential for gullying and actual gully erosion was made using the Stream Power Index (SPI) as a surrogate for critical flow shear stress. Field surveys were also conducted to assess the present condition of the gullied sites as well as to validate DEM derivations. Seventy five percent of the gullied area was noted to lie on abandoned lands. A predominance of gullying in concave bottom lands was also identified. The SPI values highlighted a distinct preferential topographic zone for gully location. A conceptual model depicting the interaction between land use and topographic parameters to induce gully erosion was developed. This should assist local authorities to develop a policy regarding management of abandoned lands.

- Description: The relationships between the spatial distribution of gully erosion and topographic thresholds in the form of slope angle, position and configuration, as well as land use change in the form of abandoned lands were examined in several affected catchments of the Eastern Cape Province, South Africa. Land use and permanent gullies were mapped, digitized from orthophoto maps in Arc/info 3.5.2 GIS and converted to shapefiles using ArcView 3.2 GIS. Relationships between the mapped phenomena and topographic variables were sought using a Digital Elevation Model (DEM) in Idrisi Kilimanjaro GIS. A comparison between areas with a high potential for gullying and actual gully erosion was made using the Stream Power Index (SPI) as a surrogate for critical flow shear stress. Field surveys were also conducted to assess the present condition of the gullied sites as well as to validate DEM derivations. Seventy five percent of the gullied area was noted to lie on abandoned lands. A predominance of gullying in concave bottom lands was also identified. The SPI values highlighted a distinct preferential topographic zone for gully location. A conceptual model depicting the interaction between land use and topographic parameters to induce gully erosion was developed. This should assist local authorities to develop a policy regarding management of abandoned lands.

- Description: preprint , This paper is part of a longer piece devoted to the elucidation of two related propositions. The first is that in South Africa the humanities in general, and Renaissance Studies in particular, are stymied by a lack of strategic thinking from those in the academy. The second is that the humanities, and Renaissance Studies, and Shakespeare, are valid and needed in this country, possibly as never before. This paper tackles the latter question, the challenge of intrinsic relevance. What possible bearing have art and literature, politics and religion, customs and technologies developed 10,000 kilometres away and nearly half a millennium ago to do with South Africa in the 21st century? I steal up on the main issue by outlining an abbreviated rhetoric of relevance, establishing a framework within which intrinsic relevance can be conceptualised for Renaissance Studies today.

- Description: Breast cancer is the most common malignancy amongst women worldwide but despite enormous efforts to address this problem, there is still limited success with most of the current therapeutic strategies. The current study describes the anti-cancer activity of a binuclear palladacycle complex (AJ-5) in oestrogen receptor positive (MCF7) and oestrogen receptor negative (MDA-MB-231) breast cancer cells as well as human breast cancer stem cells. AJ-5 is shown to induce DNA double strand breaks leading to intrinsic and extrinsic apoptosis and autophagy cell death pathways which are mediated by the p38 MAP kinase. This study provides evidence that AJ-5 is potentially an effective compound in the treatment of breast cancer.

- Description: In the intellectual tradition which we have inherited in South Africa the university as an institution is predated perhaps only by the Catholic Church. From their very beginnings universities have regarded knowledge, advanced knowledge, its preservation, extension and transmission as their very reason for existence. Modernity, if it implies a serious departure from that tradition, cannot be held as a virtue in a university. A modern university is therefore one that exists in modern times, is in tune with the intellectual needs of those times, and which adapts, without imperilling, its centuries-old outlook towards knowledge. A modern university, most emphatically, is not one which cuts itself off from its age-old intellectual roots. An institution which does so is not a modern university it in fact ceases to be a university at all.

- Description: publisher version , Plasmodium falciparum, the human pathogen responsible for the most dangerous malaria infection, survives and develops in mature erythrocytes through the export of proteins needed for remodelling of the host cell. Molecular chaperones of the heat shock protein (Hsp) family are prominent members of the exportome, including a number of Hsp40s and a Hsp70. PFA0660w, a type II Hsp40, has been shown to be exported and possibly form a complex with PfHsp70-x in the infected erythrocyte cytosol. However, the chaperone properties of PFA0660w and its interaction with human and parasite Hsp70s are yet to be investigated. Recombinant PFA0660w was found to exist as a monomer in solution, and was able to significantly stimulate the ATPase activity of PfHsp70-x but not that of a second plasmodial Hsp70 (PfHsp70-1) or a human Hsp70 (HSPA1A), indicating a potential specific functional partnership with PfHsp70-x. Protein binding studies in the presence and absence of ATP suggested that the interaction of PFA0660w with PfHsp70-x most likely represented a co-chaperone/chaperone interaction. Also, PFA0660w alone produced a concentration-dependent suppression of rhodanese aggregation, demonstrating its chaperone properties. Overall, we have provided the first biochemical evidence for the possible role of PFA0660w as a chaperone and as co-chaperone of PfHsp70-x. We propose that these chaperones boost the chaperone power of the infected erythrocyte, enabling successful protein trafficking and folding, and thereby making a fundamental contribution to the pathology of malaria. , This work was supported by grants from the National Research Foundation (NRF) and Medical Research Council (MRC) of South Africa.

The importance of phytoplankton size in mediating trophic interactions within the plankton of a southern African estuary

- Description: The influence of the phytoplankton size composition in mediating the trophic interactions between the bacteria, phytoplankton, microheterotrophs (<200 μm) and mesozooplankton (>200 μm) was investigated on three occasions in a warm temperate, temporarily open/closed estuary situated along the southern African coastline. Results of the investigation indicated that the microheterotrophs represented the most important consumers of bacteria and chlorophyll (chl)-a <5.0 μm. The low impact of the mesozooplankton on the bacteria and chl-a <5.0 μm during the study appeared to be related to the inability of the larger zooplankton to feed efficiently on small particles. During those periods when total chl-a concentration was dominated by picophytoplankton (<2.0 μm) and microphytoplankton (>20 μm), mesozooplankton were unable to feed efficiently on the chl-a due to feeding constraints. In response to the unfavorable size structure of the phytoplankton assemblages, mesozooplankton appeared to consume the microheterotrophs. The negative impact of the mesozooplankton on the microheterotrophs resulted in a decrease in the impact of these organisms on the bacteria and the chl-a <5.0 μm. This result is consistent with the predator-prey cascades. On the other hand, when the total chl-a was dominated by nanophytoplankton (2–20 μm), mesozooplankton were able to feed directly on the phytoplankton. Results of the study indicate that size structure of the phytoplankton assemblages within estuaries plays an important role in mediating the trophic interactions between the various components of the plankton food web.
