- Description: From the text: Towards a New Psychology of Women (TPNW) promises a new psychology of “women”. On the cover of the second edition, the Toronto Globe and Mail is cited as acclaiming the book as “nothing short of revolutionary” as it “set out to recognize, re-define and understand the day-to-day experience of women”. But when we take a closer look at these “women” we discover that they are in fact “white”, (for the most part) middle-class women living in heterosexual relationships in a liberal democracy. This kind of exclusionary inclusion, in which the use of the generic term “woman” disguises the normative assumptions made about the race, class, sexual orientation and location of women, replicates the phallocentrism evidenced in the normalising masculinist terms “mankind” or “Man”. By now, of course, these kinds of critiques of “white” Western feminism by African American writers (e.g. Collins, 1999) postcolonial feminists (e.g. Mohanty, 1991), African feminists (e.g. Ogundipe-Leslie, 1994; Mangena, 2003), and queer theorists (e.g. Jackson, 1999) are well known.

Written out, writing in : orature in the South African literary canon

- Description: As described by Duncan Brown, South African orature represents "our truly original contribution to world literature" (Brown, Voicing the Text 1). This paper explores how orature might be successfully 'written into' the South African literary canon whilst promoting recognition of its existence as an oral form. My recent experiences of the difficulties, challenges, and benefits of teaching South African orature within the Rhodes University English department, have alerted me to the urgent need for the creation of a student- and teacher-friendly anthology which would collect, re-voice, and adequately contextualise a selection of the seminal works of South African oral poets from the colonial to the post-apartheid periods. Much of this poetry already exists in print-form but, despite an increasing recognition of oral poetry through a number of endeavours such the Poetry Africa Festival, the Lentswe Poetry Project on SABC 2, the Timbila Poetry Project and others, South African orature remains marginal in the country's literary canon. It is largely absent from the curriculum in the literature departments of its universities. The need to redress this situation is crucial, but the process of setting up and teaching an undergraduate course in South African oral poetry, while possible, is complicated. The works of our most important oral poets are scattered in a variety of books, libraries, and collections. The usual process of drawing up a booklist of set texts is undermined by the stark reality that many of the books are out of print. Fully giving voice to these texts is even harder to achieve - CD and video recordings of performances (if they exist at all) are not easily accessed or disseminated.

- Description: This paper presents a preliminary stage in the development of an alternative parameterisation procedure for the Pitman monthly rainfall runoff model which enjoys popular use in water resource assessment in Southern Africa. The estimation procedures are based on the premise that it is possible to use physical basin properties directly in the quantification of the soil moisture accounting, runoff, and recharge and infiltration parameters. The results for selected basins show that the revised parameters are at least as good as current regionalised sets or give satisfactory results in areas where no regionalised parameters exist.

- Description: Pharmacy Education is a priority area for the International Pharmaceutical Federation (FIP), the global federation representing pharmacists and pharmaceutical scientists worldwide that is spearheading the Global Pharmacy Education Taskforce. This paper describes the work of the Taskforce that was established in March 2008, explores key issues in pharmacy education development, and describes the Global Pharmacy Action Plan 2008-2010. Given the significance of pharmacy education to the diverse practice of contemporary pharmacists and pharmacy support personnel, there is a need for pharmacy education to attain greater visibility on the global human resources for health agenda. From this perspective, FIP is steering the development of holistic and comprehensive pharmacy education and pharmacy workforce action to support and strengthen regional, national, and local efforts. The role of a global organization such as FIP is to facilitate, catalyze, and share efforts to maximize pharmacy education development and stimulate international research to develop guidance, tools, and better understanding of key issues. To achieve this goal, FIP has (1) established a formal collaborative partnership with the 2 United Nations agencies representing the education and health sectors, United Nations Educational, Scientific and Cultural Organization (UNESCO) and the World Health Organization (WHO); and (2) established the Global Pharmacy Education Taskforce to serve as the coordinating body of these efforts. The initial effort will serve to leverage strategic leadership and maximize the impact of collective actions at global, regional, and national levels. Three project teams have been convened to conduct research, consultations and develop guidance in the domains of vision for pharmacy education, competency, quality assurance, academic workforce, and institutional capacity.

Spectro-electrochemistry shows that the reduction of Mn(II)Pc to Mn(I)Pc occurs only when the complexes are in their quaternized form (5b and 6b). The reduction (to Mn(I)Pc(−2)) of the quaternized form occurs at a lower potential than that (to Mn(II)Pc(−3)) of the unquaternized form. This observation suggests that metal reduction (to Mn(I)Pc(−2)) versus ligand reduction (to Mn(II)Pc(−3)) in Mn(II)Pc complexes depends on the nature of the ring substituents.

- Description: This study constitutes the first evolutionary investigation of the snake family Psammophiidae—the most widespread, most clearly defined, yet perhaps the taxonomically most problematic of Africa's familylevel snake lineages. Little is known of psammophiid evolutionary relationships, and the type genus Psammophis is one of the largest and taxonomically most complex of the African snake genera. Our aims were to reconstruct psammophiid phylogenetic relationships and to improve characterisation of species boundaries in problematic Psammophis species complexes. We used approximately 2500 bases of DNA sequence from the mitochondrial and nuclear genomes, and 114 terminals covering all psammophiid genera and incorporating approximately 75% of recognised species and subspecies. Phylogenetic reconstructions were conducted primarily in a Bayesian framework and we used the Wiens/Penkrot protocol to aid species delimitation. Rhamphiophis is diphyletic, with Rhamphiophis acutus emerging sister to Psammophylax. Consequently we transfer the three subspecies of Rhamphiophis acutus to the genus Psammophylax. The monotypic genus Dipsina is sister to Psammophis. The two species of Dromophis occupy divergent positions deeply nested within Psammophis, and we therefore relegate Dromophis to the synonymy of Psammophis. Our results allow division of the taxonomically problematic Psammophis 'sibilans' species complex into two monophyletic entities, provisionally named the 'phillipsii' and 'subtaeniatus' complexes. Within these two clades we found support for the status of many existing species, but not for a distinction between P.p. phillipsii and P. mossambicus. Additionally, P. cf. phillipsii occidentalis deserves species status as the sister taxon of P. brevirostris.

- Description: his article will contend that the natural development of isiXhosa orature and literature, as with all South African indigenous literatures, ended with the arrival of European missionaries in 1799. The apartheid policy then exacerbated the destructive approaches to indigenous languages already in operation as it designated separate language boards for language development. These boards operated in the 'homelands' and were generally conservative, corrupt and oppressive. The manuscripts they recommended to publishers were for the most part only those that could be prescribed in schools. This resulted in the publishing of material that was parochial, apolitical and neutral in style. Often the material prescribed was written by the board members themselves. For instance, Lennox Sebe, erstwhile President of the Ciskei, produced an isiXhosa book entitled Ucamngco, for prescription, though it seems to contain little original material. Laurence Wright has shown that the opposite was true for English literature written by black South Africans and published internationally in the 1970s, at the height of apartheid (2004, 47). He describes, for instance, how one of the manuscript readers of Peteni's seminal novel, Hill of Fools (1976), rejected it as irrelevant and unsuitable for publication precisely because it made no reference to South Africa's turbulent politics. Throughout this period, however, only apolitical novels were published in the indigenous languages.

Introduced mammals decimated birds in the seventeenth century and seven endemic species are now extinct, while seven other species are locally extinct. At least nine species that now breed on St Helena have been introduced anthropogenically to the island since it was discovered. The failure to find evidence of native songbirds in the former woodlands of the interior of the island deserves explanation.

This first part of the article takes us up to the completion of the Grahamstown restoration. , Colin Lewis was Professor of Geography at Rhodes University, Grahamstown, South Africa from 1989 until his retirement at the end of 2007. In 1990, with the strong support of the incumbent Vice-Chancellor, Dr Derek Henderson, he instigated the Certificate in Change Ringing (Church Bell Ringing) in the Rhodes University Department of Music and Musicology - the first such course to be offered in Africa. Since that date he has lectured in the basic theory, and taught the practice of change ringing. He is the Ringing Master of the Cathedral of St Michael and St George, Grahamstown, South Africa.

- Description: Urban areas in developing countries will accommodate nearly 90% of the projected world population increase between 1995 and 2030. Despite this, few studies, especially in smaller towns, have been carried out on urban green space areas in the developing world. This paper makes a first step in this regard, reporting on the extent and state of urban green spaces within 10 small towns in the Eastern Cape (South Africa). After measuring the size and state (in terms of woody plant cover) of public green space, we then sought patterns across the 10 towns between green space attributes, such as area, density, mean size and proportion of alien or indigenous, with socio-economic attributes of the towns. The area and state of current public green space varied markedly between the towns, with the poorer towns faring the worst. Lower income levels were significantly negatively correlated with the area and quality of public green space. Despite this, human population density and per capita green space were the best predictors of the proportion and mean area of public green space present in the towns. The proportion of town green space and the per capita green space were the best predictors of changes in woody plant composition and density.

- Description: The limited attention afforded to push/pull activities and the motion phases (initial, sustained and ending) characteristic of these tasks has prompted a research focus in this area. The present study examined biomechanical responses in the form of hand forces during dynamic submaximal trolley pushing and pulling. Participants pushed/pulled loads of 100, 200 and 300 kg on the level (determining impact of load) or pushed 100 kg along a 12° ramp (uphill and downhill- determining impact of gradient). During level exertions significant differences (p<0.05) in hand forces occurred between loads of 100 and 200 kg, and 100 and 300 kg for initial and sustained forces but not ending forces. Values were similar for pushing and pulling at respective loads and motion phases. Strong correlations indicate that initial forces can be used to accurately estimate sustained and ending forces. Importantly, correct technique is essential in force reduction. Forces were highest during uphill initial and sustained phases and the downhill sustained phase. For the initial phase, the forces were highest during uphill pushing (86.5 ± 25.73 N); for the sustained phase, there was no difference between uphill and downhill forces but level forces were significantly lower (18.19 ± 8.09 N) than either of the other two conditions; for the ending phase, the highest forces were produced during downhill pushing (-53.34 ± 13.65N). As sustained forces equaled or exceeded initial forces for uphill and downhill efforts, consideration of sustained forces may be appropriate in determining the inherent potential risk of graded pushing.

- Description: The concentrations of select metals (Cd, Co, Cu, Fe, Pb, Ni and Zn) within the water column and sediment of the permanently open Kariega Estuary and temporary open / closed Riet and East Kleinemonde Estuaries were investigated during a dry and a wet season. Enrichment factors (EFs), using Fe as a reference element, and baseline linear regression models for metals vs Fe were used to assess the extent of metal enrichment in the sediments. The results of the study indicate that Cd, Co Ni and Pb were enriched above baseline concentrations (1.0 < EF < 4.1) in the sediments of all three estuaries. Co, Pb and Ni enrichment in the Kariega Estuary sediments was significantly higher during the dry season, and the mean concentrations of Pb and Cd in the water column were 19-fold and 66-fold higher in the dry season. The elevated concentration of metals during the dry season could be related to accumulation of diffuse pollution from human activities within the catchment area. Conversely, inflow of freshwater into the estuary had the net effect of reducing the concentration and enrichment of these metals within the Kariega Estuary due to scouring and outflow of estuarine water and sediment into the marine environment. The temporal variations in metal concentrations and enrichment factors were less pronounced in the temporary open / closed estuaries than the Kariega Estuary. The observed trend can probably be related to the low anthropogenic impact within the catchment areas of these systems, and the relatively smaller size of the catchments. Significant spatial variations existed in metal enrichment in the sediment of both the East Kleinemonde and Riet Estuaries, with the highest degrees of enrichment occurring in the sediments from the marine environment and lower reaches.

- Description: This article reports a clinical case study of "Grace", a black Zimbabwean woman with post-abortion syndrome (PAS), a form of post-traumatic stress disorder precipitated by aborting an unwanted pregnancy. She was treated by a middle class white South African trainee Clinical Psychologist. The case narrative documents the assessment and the course of treatment which was guided by ongoing case formulation based on current evidence-based models. Factors that made her vulnerable to developing PTSD included active suppression of the memory of the event and lack of social support. An understanding of these factors was used to guide an effective intervention. In spite of the differences in culture and background between client and therapist, there was considerable commonality in their experience as young women and students who each had to balance personal and occupational priorities. The narrative also highlights the commonalities of Grace's experiences with those reported in the literature on post-abortion syndrome, which is mostly from the U. S. A. and Europe.

- Description: From the theoretical perspective of René Girard, Walter Benjamin and Jacques Derrida the Rwanda genocide of 1994 may be interpreted as an instance of foundational violence. Given the constant reference in the Rwanda genocide discourse to the failed revolution of 1959, it is perhaps rather a case of deferred foundational violence. Useful as this notion of “foundational violence” may be, as theoretical category it is also hugely challenging because the implicit claim is not just historical (“states are routinely founded on violence”) but analytical (“founding moments are per definition violent”). The result is a profound tension between, on the one hand, the need to understand the event as somehow unexceptional or typical of the founding of new socio-political orders and, on the other hand, the need to judge it as exceptional, an “outrage,” a crime against humanity. This paper treats the tension between the unexceptional and exceptional as aporetic, that is, as a profound puzzle consisting of two equally valid imperatives which are nonetheless mutually exclusive. It is also an attempt to find a way beyond the impasse.

- Description: This article uses ‘close-up’ ethnographic research to provide an account of students’ engagement with learning in a South African university. Broadly based on Halliday’s (1973, 1978, 1994) understanding of texts resulting from contexts, the account challenges dominant constructions of the problems students encounter as stemming from the use of inappropriate ‘approaches’ to learning, the lack of ‘study’ and other skills or problems with proficiency in areas such as writing or language and shows how students’ unfamiliarity with the context of the university leads them to draw on ‘other’ contexts in order to engage with the texts they must read, write and listen to in the course of their studies. This drawing on ‘other’ contexts then results in the texts produced by students, and the practices which give rise to those texts, being inappropriate to the context of the university. Although the research on which the article is based took place in South Africa, it is argued that the theoretical perspective it provides has relevance across other contexts given the increasingly diverse student bodies which characterize higher education across the globe.

- Description: Temporal changes in hydrography affect suspended particulate matter (SPM) composition and distribution in coastal systems, potentially influencing the diets of suspension feeders. Temporal variation in SPM and in the diet of the mussel Perna perna, were investigated using stable isotope analysis. The δ13C and δ15 N ratios of SPM, mussels and macroalgae were determined monthly, with SPM samples collected along a 10 km onshore–offshore transect, over 14 months at Kenton-on-Sea, on the south coast of South Africa. Clear nearshore (0 km) to offshore (10 km) carbon depletion gradients were seen in SPM during all months and extended for 50 km offshore on one occasion. Carbon enrichment of coastal SPM in winter (June–August 2004 and May 2005) indicated temporal changes in the nearshore detrital pool, presumably reflecting changes in macroalgal detritus, linked to local changes in coastal hydrography and algal seasonality. Nitrogen patterns were less clear, with SPM enrichment seen between July and October 2004 from 0 to 10 km. Nearshore SPM demonstrated cyclical patterns in carbon over 24-h periods that correlated closely with tidal cycles and mussel carbon signatures, sampled monthly, demonstrated fluctuations that could not be correlated to seasonal or monthly changes in SPM. Macroalgae showed extreme variability in isotopic signatures, with no discernable patterns. IsoSource mixing models indicated over 50% reliance of mussel tissue on nearshore carbon, highlighting the importance of nearshore SPM in mussel diet. Overall, carbon variation in SPM at both large and small temporal scales can be related to hydrographic processes, but is masked in mussels by long-term isotope integration.
