- Description: Badiou’s ontological work draws attention to multiplicities – the oneness of ontology, which he explains can only become ontologically differentiated into events or sites through political, artistic or amorous practices that philosophies can think and invent from. He also draws attention to the fusion of events and sites, and he explains that events (such as producing special issues of journals located in particular sites) are reflexive. He also tells us, however, that the reflexive structure of an artistic or scientific event (such as producing a special issue of a journal) is not always immediately evident. In writing this response article I work with this concept – and probe how the production of events (such as a special issue of a journal produced in a specific site) may be reflexive. This is the purpose of the article. This response article therefore probes some of the political, structural and intellectual processes that come to shape scholarship in different sites, and here I draw on the insights into social imaginaries provided by Charles Taylor to develop a perspective on the scholarship that is reflected in this journal. Through this, I seek to open the notion of multiplicities, oneness and the particularities of our social imaginaries as themes for thinking about educational scholarship events produced within and across geo‐physical, socio‐ecological and socio‐economic spaces in different parts of the world.

- Description: The Fourth Assessment Report of the Intergovernmental Panel on Cli-mate Change (IPCC 2007) identifi es Africa as one of the continents of the world most vulnerable to climate change. Africa’s vulnerability to climate change is aggravated by the interaction of multiple stresses such as poverty, poor governance, and weak institutions, limited access to capi-tal (including technology), ecosystem degradation, confl ict and disasters (UNEP 2006), and a generally poor quality of education (UNESCO 2004). The climate injustices and exacerbating circumstances experienced by poor and weak states today lie in the long-term historical emergence of a modern (and increasingly global) world order framed by a hegemonic Westphalian state system. This state system privileges exclusive, undi-vided sovereignty over a bounded territory (Fraser 2008), and is known more popularly as the ‘nation state’ system.

- Description: Medicocriminal forensic entomology focuses primarily on providing evidence of the amount of time that a corpse or carcass has been exposed to colonization by insects, which helps to estimate the post mortem interval (PMI). Specifically, the estimate is of a minimum post mortem interval (PMImin), because death may occur a variable amount of time before colonization (Fig. 7.1); the maximum post mortem interval (PMImax) is estimated using the time that the person was last seen alive. Forensic entomology derives the bulk of its evidence from two sources: the ecological succession of carrion insect communities and the development of immature insects (Byrd and Castner 2001; Catts and Haskel 1990; Smith 1986). This chapter is concerned with assessing the confidence that can be placed in the accuracy of estimates derived from insect development. (Schoenly et al. 1996) dealt with this theme in succession-based estimates of PMImin.

- Description: In observing and plotting the dialectics of how our present world works, fragmenting as it integrates we struggle in wanting to pin down a moving target! Unlike the world of science with its physical laws, the social nature of the world and its relations across borders keep changing course with social and transnational relations constantly mutating. This makes it rather difficult to plot the complexity of human relations, also those across borders. As the late Nobel Laureate Herbert Simon once said, the social sciences are, after all, the really ‘hard’ sciences. They are so hard because they are so hard to explain.

- Description: This paper describes the assumptions and results of a study to assess whether cultivation of medicinal plants can serve as a tool for combined biodiversity conservation and poverty alleviation. The study was carried out in the Amatola region of Eastern Cape, South Africa, where sustained beliefs in medicinal plant use, also under non-traditional conditions, has resulted in an increase in commercial demands. It was based on the assumption of poverty alleviation not only referring to an increase in income and labour, but also an increase in social capital and human dignity. The study assessed the local perceptions of the use and cultivation of medicinal plants and the need for conservation of these plants, as well as the features of already ongoing cultivation practices and options for increased cultivation. It consisted of participatory assessments in three villages involving around 250 persons and participatory trials with 14 rural women selling medicinal plants on urban markets. The study indicated that the growing demand for medicinal plants is related to the great cultural significance attached to medicinal plants.

Findings from 2002 Computer Crime and Security Survey show an upward trend that demonstrates a need for a timely review of existing approaches to fighting this new phenomenon in the information age. In this paper, we provide an overview of Cybercrime and present an international per-spective on fighting Cybercrime. This work seeks to define the concept of cyber-crime, explain tools being used by the criminals to perpetrate their evil handiworks, identify reasons for cyber-crime, how it can be eradicated, look at those involved and the reasons for their involve-ment, we would look at how best to detect a criminal mail and in conclu-sion, proffer recommendations that would help in checking the increas-ing rate of cyber-crimes and criminals.

- Description: This paper considers the complexities involved in obtaining training da-ta for use by artificial intelligence constructs to identify potential network incidents using passive network telescope data. While a large amount of data obtained from network telescopes exists, this data is not current-ly marked for known incidents. Problems related to this marking process include the accuracy of the markings, the validity of the original data and the time involved. In an attempt to solve these issues two methods of training data generation are considered namely; manual identification and automated generation. The manual technique considers heuristics for finding network incidents while the automated technique considers building simulated data sets using existing models of virus propagation and malicious activity. An example artificial intelligence system is then constructed using these marked datasets.

David Lurie's learning and the meaning of J.M. Coetzee's Disgrace

- Description: preprint , One of the teasing characteristics of novels soused in literariness, like J.M. Coetzee’s, is their tendency to leak, to bleed, into vast inchoate terrains of intertextuality.The reader is constantly challenged to measure and assess their implications within or against the frail containing form of the story, much as Russian formalism taught us to keep sujet and fable in perpetual dialogue. However, it has become apparent that in the dense thickets of commentary occasioned by Coetzee’s most controversial novel, Disgrace (1999), insufficient attention has been paid to the intertextual implications of David Lurie’s learning, his scholarly preoccupations. Unless the reader attempts this kind of exploration, two of the most vexed issues freighting the novel’s central fabulation: Lucy’s curiously stoical, impassive response to her rape, together with her decision to stay on in South Africa; and David Lurie’s sudden, seemingly inexplicable care for the doomed dogs, from their last moments at the animal shelter until he lovingly consigns their corpses to the incinerator, must remain opaque. In particular, the final words of the novel, “Yes, I am giving him up” (220), uttered in relation to the immanent “Lösung” of the little dog Bev Shaw calls Driepoot, will tend to taunt the reader, rather than illuminate.

- Description: A stability-indicating high performance liquid chromatographic(HPLC) method was developed and validated for the quantitation and dissolution determination of topiramate in tablet dosage forms. An isocratic separation was achieved using a phenyl column with a flow rate of 1 mL/min using UV detection at 264 nm. Topiramate has low UV absorbtivity and was subjected to derivatization with 9-fluorenylmethyl chloroformate (FMOC-Cl). The mobile phase for the separation consisted of acetonitrile: 50 mM sodium dihydrogen phosphate(NaH2PO4) containing 3 % v/v triethylamine (pH 2.8) in a 48:52 v/v ratio. Topiramate was subjected to oxidation, hydrolysis, photolysis and heat for the purposes of stress testing. Separation was achieved for the parent compound and all the degradation products in an overall analytical run time of approximately 15 min with the parent compound topiramate eluting at approximately 9.2 min. The method was linear over the concentration range of 1-100 μg/mL (r = 0.9996) with limits of quantitation and detection of 1 and 0.3 μg/mL, respectively.

- Description: Several open source SIP/IMS Clients are currently in use in the Rhodes University Convergence Research Group. However, there is no single Client that provides researchers with all the required functionality need-ed to test the applications they have developed. Integrating advanced features into a single Client can help to speed up testing as well as pro-vide a variety of innovative communication services. In this paper we present an overview of two popular SIP/IMS Clients currently in use. We also discuss the features and design architecture of a Client called JAIN SIP Applet Phone (JSAP) which will be used as a basis for the development of a new IMS compliant Client. We then analyse what functionality JSAP lacks and propose features that need to be imple-mented.

- Description: The theme of reconciliation remains an important one in South African politics. The issue of reconciliation was recently highlighted by South African Human Rights Commission chairperson, Jody Kollapen. According to Kollapen, in South Africa we have a problematic narrow interpretation of reconciliation, one that presents reconciliation and transformation as being in opposition to one another. This paper explores some of the debates about reconciliation as a process and then relates these to the Home for All Campaign. This Campaign was aimed at encouraging white South Africans to acknowledge the injustices of the past and to commit themselves to healing divisions and reducing inequalities in contemporary South Africa. It conceived of reconciliation as a process in which the onus is on white South Africans to take the initiative in reconciling with black South Africans. The Campaign received much publicity and provoked debate but never managed to gain the support of a significant number of white South Africans. In this paper, I explore the reasons for the Campaign's failure to meet all of its objectives, relating this to contemporary South African discourse on reconciliation. I argue that the Campaign's interpretation of reconciliation was valuable and necessary and that it remains imperative in South Africa that white South Africans critically reflect upon past and present privileges and take the initiative in processes of inter-racial reconciliation.

- Description: The diet and growth of sharptooth catfish, Clarias gariepinus, in an oligotrophic system (Kat River Reservoir, Eastern Cape, South Africa) were compared to those in a eutrophic system (Laing Reservoir, Eastern Cape) to determine if the trophic status of a waterbody had an effect on the growth rate of the species. In order of importance, the diet of catfish in Kat River Reservoir consisted of fish, insects, zooplankton, plant material and other items, while the diet of catfish in Laing Reservoir consisted of fish, plant material, zooplankton, other vertebrates and insects. The diets of catfish in the two reservoirs had a similarity index of 68.1% and there was no significant difference in their nutritional value. Fish prey was the most important dietary component in both reservoirs. Temperature regime and zooplankton and zoobenthos density were similar in both systems. However, fish prey density was significantly higher in the eutrophic Laing Reservoir and catfish grew significantly faster in that system. The slower growth rate in Kat River Reservoir was attributed to the higher energy costs associated with the capture of fish prey, which was less abundant than in Laing Reservoir. Trophic status therefore had an indirect effect on catfish growth by influencing the availability of fish prey.

- Description: Impacts of large dams are well-known and quantifiable, while small dams have generally been perceived as benign, both socially and envi-ronmentally. The present study quantifies the cumulative impacts of small dams on the water quality (physico-chemistry and invertebrate biotic indices) and quantity (discharge) of downstream rivers in 2 South African regions. The information from 2 South African national data-bases was used for evaluating the cumulative impacts on water quality and quantity. Physico-chemistry and biological data were obtained from the River Health Programme, and discharge data at stream flow gauges was obtained from the Hydrological Information System. Multivariate analyses were conducted to establish broad patterns for cumulative impacts of small dams across the 2 regions–Western Cape (winter rain-fall, temperate, south-western coast) and Mpumalanga (summer rain-fall, tropical, eastern coast). Multivariate analyses found that the chang-es in macroinvertebrate indices and the stream’s physico-chemistry were more strongly correlated with the density of small dams in the catchment (as a measure of cumulative impact potential) relative to the storage capacity of large dams. T-tests on the data, not including sam-ples with upstream large dams, indicated that the high density of small dams significantly reduced low flows and increased certain physico-chemistry variables (particularly total dissolved salts) in both the re-gions, along with associated significant reductions in a macroinverte-brate index (SASS4 average score per taxon). Regional differences were apparent in the results for discharge reductions and the macroin-vertebrate index. The results suggest that the cumulative effect of a high number of small dams is impacting the quality and quantity of wa-ters in South African rivers and that these impacts need to be systemat-ically incorporated into the monitoring protocol of the environmental wa-ter requirements.

- Description: This paper investigates the cumulative impacts of small dams on invertebrate communities in 2 regions of South Africa – the Western Cape and Mpumalanga. Previous research found reduced discharge, increased total dissolved salts, and a decrease in average score per taxon (ASPT; collected using SASS4 methods) at sites with high density of small dams in their catchment. These changes in ASPT are investigated using the invertebrate abundance data available in the River Health Programme. Multivariate analyses found differences in invertebrate communities in rivers with high densities of small dams in their catchment in foothill-gravel streams (in both Western Cape and Mpumalanga) and in foothill-cobble streams (in Western Cape only). Opportunistic taxa that are tolerant of pollution, and capable of exploiting various habitats, and those that prefer slower currents increased in numbers, while other taxa that are sensitive to pollution and disturbance declined in numbers. Some regional differences were noted possibly reflecting climatic differences between the regions. Since the results of this study are correlative, it highlights the need for a systematic (by sites and seasons) and detailed (at species level) collection of data to verify the results of cumulative effects of small dams. This can further the development of a framework for small-dam construction and management that will limit their impact on river catchments.
