- Description: This thesis examines selected speculative novels by Margaret Atwood, Ursula K. Le Guin, Doris Lessing and Marge Piercy. It argues that a specifiable ecological ethic can be traced in their work – an ethic which is explored by them through the tensions between utopian and dystopian discourses. The first part of the thesis begins by theorising the concept of an ecological ethic of respect for the Other through current ecological philosophies, such as those developed by Val Plumwood. Thereafter, it contextualises the novels within the broader field of science fiction, and speculative fiction in particular, arguing that the shift from a critical utopian to a critical dystopian style evinces their changing treatment of this ecological ethic within their work. The remainder of the thesis is divided into two parts, each providing close readings of chosen novels in the light of this argument. Part Two provides a reading of Le Guin’s early Hainish novels, The Left Hand of Darkness, The Word for World is Forest and The Dispossessed, followed by an examination of Piercy’s Woman on the Edge of Time, Lessing’s The Marriages Between Zones Three, Four and Five, and Atwood’s The Handmaid’s Tale. The third, and final, part of the thesis consists of individual chapters analysing the later speculative novels of each author. Piercy’s He, She and It, Le Guin’s The Telling, and Atwood’s Oryx and Crake are all scrutinised, as are Lessing’s two recent ‘Ifrik’ novels. This thesis shows, then, that speculative fiction is able to realise through fiction many of the ideals of ecological thinkers. Furthermore, the increasing dystopianism of these novels reflects the greater urgency with which the problem of Othering needs to be addressed in the light of the present global ecological crisis.

"Form fading among fading forms" death, language and madness in the novels of Samuel Beckett

- Description: The primary thesis of this dissertation is that the development of narrative strategy and technique through the course of Samuel Beckett’s fictional oeuvre enacts a parody of the Cartesian method of doubt, in which the search for first principles, instead of providing grounds for certainty, is a hopeless, grotesque quest for a self which eludes any and every assertion. My chief concerns are thus, firstly, to explicate and elucidate the nature of such narrative strategies and techniques, and how these can be said to parody epistemological procedure; and secondly, to interrogate the implications of this parody for the epistemological and interpretative endeavour of which the human sciences are comprised. These two issues are explored by way of an examination of Beckett’s earliest novel, Murphy, and the narrative impasse that arises from the contradiction between this work’s largely realist form and quasi-postmodern content. I thereafter argue that the later fiction, most particularly the Trilogy, achieves formal and stylistic solutions to the aesthetic and epistemological challenges raised by the earlier work. Beckett’s fictional oeuvre, I contend, can best be construed as an attempt to attain that which exceeds and escapes narrative in and through narrative, namely madness or death. The achievement of either would entail the obliteration of the possibility of narrating at all, and the novels, engaging in a self-deconstructing endeavour, thus occupy a profoundly paradoxical position. Any attempt to interpret a body of work of this nature can only respond in an analogous manner, by trying to make meaning of the subversion of meaning, and deconstructing the assumptions that inform its procedures. This dissertation argues that it is precisely in the way in which it necessitates such selfreflexive discursive analysis that the import of Samuel Beckett’s fiction lies, and extrapolates the significance of this for an understanding of discourse, literary criticism, and epistemological procedure.

- Description: Heiner Müller’s most famous play (Die Hamletmaschine, 1977) has evolved into something of a familiar war-horse for student theatre. The United States in particular has taken to the work; indeed, it was meant in part for them: “Heil Coca-cola!” says the script. For today’s South African ears this has become, very aptly, “Hail the Rainbow Nation!” What young director can resist it? Only eight pages in extent, the sparse yet densely referential text offers unfettered scope for interpretation and contextualization. Sure, the original offered Muller’s despairing take on the collapse of western civilisation, typified in the East German predicament where intellectuals felt trapped between the total failure of ‘actually existing socialism’ – that ideological mirage – in the German Democratic Republic, and the horrors of emergent bandit capitalism presaging an uncomfortable future. But the spaces in the text are so capacious that almost any claim to climactic despair can be entertained: idiot consumerism, gender oppression and aggression, political treachery and malfeasance, fascism, existential angst, intellectual cowardice, the postmodern condition, the rejection of hope.

- Description: This thesis argues that a prominent concern among contemporary writers of fiction is the recuperation of lost or occluded histories. Increasingly, contemporary writers, especially postcolonial writers, are using the medium of fiction to explore those areas of political and cultural history that have been written over or unwritten by the dominant narrative of “official” History. The act of excavating these past histories is simultaneously both traumatic and liberating – which is not to suggest that liberation itself is without pain and trauma. The retelling of traumatic pasts can lead, as is portrayed in The God of Small Things (1997), to further trauma and pain. Postcolonial writers (and much of the world today can be construed as postcolonial in one way or another) are seeking to bring to the fore stories of the past which break down the rigid binaries upon which colonialism built its various empires, literal and ideological. Such writing has in a sense been enabled by the collapse, in postcolonial and postmodernist discourse, of the Grand Narrative of History, and its fragmentation into a plurality of competing discourses and histories. The associated collapse of the boundary between history and fiction is recognized in the useful generic marker “historiographic metafiction,” coined by Linda Hutcheon. The texts examined in this study are all variants of this emerging contemporary genre. What they also have in common is a concern with the consequences of exile or diaspora. This study thus explores some of the representations of how the exilic experience impinges on the development of identity in the postcolonial world. The identities of “displaced” people must undergo constant change in order to adjust to the new spaces into which they move, both literal and metaphorical, and yet critical to this adjustment is the cultural continuity provided by psychologically satisfying stories about the past. The study shows that what the chosen texts share at bottom is their mutual need to retell the lost pasts of their characters, the trauma that such retelling evokes and the new histories to which they give birth. These texts generate new histories which subvert, enrich, and pre-empt formal closure for the narratives of history which determine the identities of nations.

- Description: This research investigates contemporary South African performance within the context of prominent social and cultural change following the political transition from an apartheid state to democracy. Specifically, it looks at the relationship between a popular comic variety show The Most Amazing Show (TMAS), and aspects of contemporary South African society and culture, particularly relating to prominent efforts to affect post-election transformation of South African society and culture through the construction of a South African 'rainbow nation'. By analysing TMAS in terms of broader historical, performative and discursive contexts, it engages a relational reading of the performance. The study argues that TMAS both challenges and participates in the manner in which rainbow nation discourse constructs South African society and culture. Firstly, it considers the performance's construction of hybrid South African identities, including white Afrikaans, white English and white masculine identities. It argues that these reconstructions undermine the tendency within rainbow nation discourse to construct cultural hybridity in terms of stereotypically distinct identities. Secondly, it considers TMAS' construction of collective experience and social integration, which subvet1s the often glamorised and superficial representations of social healing and integration that are constructed within rainbow nation discourse. The analysis makes prominent reference to the notion of 'liminality' in order to describe the manner in which TMAS constructs significance within the tension that it establishes between oppositional, and often contradictory, positions. Furthermore, it attempts to establish a link between this notion of liminality and no6ons of theatrical syncretism that are prominent in contemporary South African theatre scholarship, and emphasise processes of signification that are constantly shifting and unstable.

- Description: Knowledge integration is one of the key principles that underpin curriculum reform in post-apartheid South Africa. One form of teacher support that has been adopted in South Africa is to provide schools throughout the country with samples of pedagogic texts such as curriculum documents and examination exemplars to act as guidelines to teachers as they implement this new curriculum requirement. In the isolated and under-resourced rural schools of South Africa, these texts are the main form of curriculum guidance to teachers. Hence the knowledge integration principles and messages conveyed within these texts are of crucial importance. One contributory factor to the lack of information on knowledge integration at rural underresourced schools is the lack of simple and effective research tools by which to analyse and compare the extent of knowledge integration within pedagogic texts and classroom practices. This article reports on a Bernstein informed analysis that was carried out on three different Grade 10 Life Sciences pedagogic texts in order to assess the extent to which they integrate natural resource management (NRM). The study involved the construction of two indicator frameworks as the research tools with which the analysis was conducted. Results from the analysis showed that although the official Grade 10 Life Sciences pedagogic texts contained very high levels of NRM integration, this was not the case for the Grade 10 Life Sciences text that was produced at the school level. The study provides useful insight into curriculum recontextualisation at a rural under-resourced school through the lens of NRM integration within the Grade 10 Life Sciences pedagogic texts. Such insight has the potential to contribute to better curriculum design and implementation strategies to service schools. This will hopefully help to narrow the gap that currently exists between the official and enacted curricula.

- Description: Syntheses of Schiff bases were carried out by reacting salicylaldyhde, ortho-vanillin, para-vanillin or vanillin with aniline, 1-aminonaphthalene, 4- and 3-aminopyridine, and also with 2- and 3-aminomethylpyridine. The various Schiff bases obtained from the condensation reaction were reacted with CoCl₂.6H₂0, triethylamine stripped CoCl₂.6H₂0 or Co(CH₃COO)₂ to form cobalt(Il) complexes of ratio 2:1. The complexes obtained from cobalt chloride designated as the "A series" are of the general formulae ML₂X₂.nH₂0 , (L = Schiff base, X = chlorine) while those obtained from cobalt acetate or triethylamine stripped cobalt chloride denoted as "B" and C" are of the general formulae ML₂. nH₂0. The few complexes that do not follow the general formulae highlighted above are: IA [M(HL)₃.Cl₂], (L = N-phenylsalicylaldimine), 4A = (MLCl₂), (L = N-phenylvanaldiminato), 7 A and 21 A (ML₂), (L = N-naphthyl-o-vanaldiminato, and N-methy-2-pyridylsalicylaldiminato respectively), 8A = MLCI, (L = N-naphthylvanaldiminato), 12A = M₂L₃Cl₂, (L = N-4-pyridylvanaldiminato), 15A (MLCI), (L = N-3-pyridyl-o-vanaldiminato). The ligands and their complexes were characterized using elemental analyses and cobalt analysis using ICP, FT-IR spectroscopy (mid and far-IR), NIR-UV/vis (diffuse reflectance), UV/vis in an aprotic and a protic solvents, while mass spectrometry, ¹HNMR and ¹³CNMR, was used to further characterized the ligands. The tautomeric nature of the Schiff bases were determined by examining the behaviour of Schiff bases and their complexes in a protic (e.g. MeOH) and non-protic (e.g. DMF) polar solvents. The effects of solvents on the electronic behaviour of the compounds were also examined. Using CDCl₃, the NMR technique was further used to confirm the structures of the Schiff bases. The tentative geometry of the complexes was determined using the spectra information obtained from the far infrared and the diffuse reflectance spectroscopy. With few exceptions, most of the "A" series are tetrahedral or distorted tetrahedral, while the "B + C" are octahedral or pseudooctahedral. A small number of complexes are assigned square-planar geometry owing to the characteristic spectral behaviour shown. In order to determine their biological activity, two biological assay methods (antimicrobial testing and brine shrimp lethality assay) were used. Using disc method, the bacteriostatic and fungicidal activities of the various Schiff bases and their respective complexes to Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa as well as Aspergillus niger, were measured and the average inhibition zones are tabulated and analysed. Both the Schiff bases and their complexes showed varying bacteriostatic and fungicidal activity against the bacteria and fungus tested. The inhibition activity is concentration dependent and potential antibiotic and fungicides are identified. To determine the toxicity of the ligands and their corresponding cobalt(II) complexes, brine shrimp lethality assay was used. The LD₅₀ of the tested compounds were calculated and the results obtained were tabulated for comparison.

- Description: Syntheses of Schiff bases were carried out by reacting salicylaldyhde, ortho-vanillin, para-vanillin or vanillin with aniline, 1-aminonaphthalene, 4- and 3-aminopyridine, and also with 2- and 3-aminomethylpyridine. The various Schiff bases obtained from the condensation reaction were reacted with CoCl₂.6H₂0, triethylamine stripped CoCl₂.6H₂0 or Co(CH₃COO)₂ to form cobalt(Il) complexes of ratio 2:1. The complexes obtained from cobalt chloride designated as the "A series" are of the general formulae ML₂X₂.nH₂0 , (L = Schiff base, X = chlorine) while those obtained from cobalt acetate or triethylamine stripped cobalt chloride denoted as "B" and C" are of the general formulae ML₂. nH₂0. The few complexes that do not follow the general formulae highlighted above are: IA [M(HL)₃.Cl₂], (L = N-phenylsalicylaldimine), 4A = (MLCl₂), (L = N-phenylvanaldiminato), 7 A and 21 A (ML₂), (L = N-naphthyl-o-vanaldiminato, and N-methy-2-pyridylsalicylaldiminato respectively), 8A = MLCI, (L = N-naphthylvanaldiminato), 12A = M₂L₃Cl₂, (L = N-4-pyridylvanaldiminato), 15A (MLCI), (L = N-3-pyridyl-o-vanaldiminato). The ligands and their complexes were characterized using elemental analyses and cobalt analysis using ICP, FT-IR spectroscopy (mid and far-IR), NIR-UV/vis (diffuse reflectance), UV/vis in an aprotic and a protic solvents, while mass spectrometry, ¹HNMR and ¹³CNMR, was used to further characterized the ligands. The tautomeric nature of the Schiff bases were determined by examining the behaviour of Schiff bases and their complexes in a protic (e.g. MeOH) and non-protic (e.g. DMF) polar solvents. The effects of solvents on the electronic behaviour of the compounds were also examined. Using CDCl₃, the NMR technique was further used to confirm the structures of the Schiff bases. The tentative geometry of the complexes was determined using the spectra information obtained from the far infrared and the diffuse reflectance spectroscopy. With few exceptions, most of the "A" series are tetrahedral or distorted tetrahedral, while the "B + C" are octahedral or pseudooctahedral. A small number of complexes are assigned square-planar geometry owing to the characteristic spectral behaviour shown. In order to determine their biological activity, two biological assay methods (antimicrobial testing and brine shrimp lethality assay) were used. Using disc method, the bacteriostatic and fungicidal activities of the various Schiff bases and their respective complexes to Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa as well as Aspergillus niger, were measured and the average inhibition zones are tabulated and analysed. Both the Schiff bases and their complexes showed varying bacteriostatic and fungicidal activity against the bacteria and fungus tested. The inhibition activity is concentration dependent and potential antibiotic and fungicides are identified. To determine the toxicity of the ligands and their corresponding cobalt(II) complexes, brine shrimp lethality assay was used. The LD₅₀ of the tested compounds were calculated and the results obtained were tabulated for comparison.

- Description: Falling within the ambit of the Department of English Literature but with interdisciplinary scope and method, the research undertaken in this thesis examines Michael Radford’s 2004 film production William Shakespeare’s The Merchant of Venice using the Book History approach to textual study. Previously applied almost exclusively to the study of books, Book History examines the text in terms of both its medium and its content, bringing together bibliographical, literary and historical approaches to the study of books within one theoretical paradigm. My research extends this interdisciplinary approach into the filmic medium by using a modified version of Robert Darnton’s “communication circuit” to examine the process of transmission of this Shakespearean film adaptation from creation to reception. The research is not intended as a complete Book History study and even less as a comprehensive investigation of William Shakespeare’s The Merchant of Venice. Rather, it uses a Shakespearean case study to bring together the two previously discrete fields of Book History and filmic investigation. Drawing on film studies, literary concepts, cultural and media studies, modern management theory as well as reception theories and with the use of both quantitative and qualitative data, I show Book History to be an eminently useful and constructive approach to the study of film.

- Description: Although many vectors exist for Escherichia coli and closely related species, there are few broad host range vectors that can be conjugated into a large variety of Gram-negative bacteria. We have constructed a broad host range vector, pMJ445, that facilitates the analysis of divergent promoters in Gram-negative bacteria. The vector was validated using two intergenic regions derived from gene clusters involved in hydantoin hydrolysis, from the environmental isolates Pseudomonas putida and Agrobacterium tumefaciens. The DNA sequences analysed were capable of activating expression of the reporter enzymes, β-glucuronidase and β-galactosidase, present on pMJ445, indicating the presence of divergent promoters in the sequences selected. In addition, we demonstrated that pMJ445 can be applied to gene regulation studies.

- Description: This paper will present an implementation of the Advanced Encryption Standard (AES) on the graphics processing unit (GPU). It investigates the ease of implementation from first principles and the difficulties encountered. It also presents a performance analysis to evaluate if the GPU is a viable option for a cryptographics platform. The AES implementation is found to yield orders of maginitude increased performance when compared to CPU based implementations. Although the implementation introduces complica-tions, these are quickly becoming mitigated by the growing accessibility pro-vided by general programming on graphics processing units (GPGPU) frameworks like NVIDIA’s Compute Uniform Device Architechture (CUDA) and AMD/ATI’s Close to Metal (CTM).

A case for institutional investigations in economic research methods with reference to South Africa's agricultural sector

- Description: Economic development remains elusive for many world economies, but especially those of African countries. The current global inequalities in terms of GNP per capita and human living standards between developed and developing nations have ensured that the challenges of food insecurities are only some of the many negative experiences of underdevelopment in the African continent. Hence, delivery pressures are increasing on policy makers and researchers to provide tangible and timely economic solutions to the resilient state of underdevelopment. In the policy fights against the challenges posed by a lack of development in South Africa, the agricultural sector has in the past and continues in the present to play a central role. Such is the case because the majority of citizens rely on agricultural production activities for their livelihoods. For instance, even though the sector only contributed four percent towards the national Gross Domestic Product in 2006, in the Eastern Cape Province, more than seventy percent of the total population resided in rural areas. Moreover, in 2004 more than sixty percent of the national formal and informal employment levels were found in the sector. These economic indicators do not only reinforce the assertions that high levels of geographical and sectoral inequalities exist in the country’s economy, but they also illustrate the importance of the agricultural sector in public policy attempts, which are aimed at achieving food security alongside long-term developmental objectives. Some economists, especially the proponents of institutionalism, have argued that most of the recommendations to public policy interventions from mainstream economic research endeavours are not adequately helpful. The recommendations generally lack well considered and socially effective ideas, mainly because there remains some level of ignorance about the impacts that institutions have on economic and social systems. Some argue that this ignorance is reflected in (flawed) hedonistic and rationalist assumptions made about economic actors and in the methodological thinking of many research designs and economic analyses. The misuse of formal tools and statistical methods, for example, are some of the important factors, which have led to failures of the discipline of economics to provide effective policy solutions to problems of underdevelopment and poverty, especially in poor country environments. The thesis, having taken account of the majority of criticisms levelled against the classical and new-classical economic schools of thought, argues that the discipline as a whole lacks a paradigmatic integration of institutional and new-classical economic perspectives to offer appropriate guidelines for a methodology aimed at achieving socially responsive research outputs. The lack of this integration has resulted in a skewed selection of methods by economists, which are employed in research without a supportive and in-depth understanding of institutional and social factors. To support the thesis, a more effective and integrated framework for economic research is developed and presented with case study illustrations in a cumulative manner. The 20th century history of agricultural policies in South Africa, the agricultural and institutional case studies from the Eastern Cape Province alongside reviews of other agricultural studies are all used in presenting a case for rigorous institutional investigations in general economic research. These are also used in developing the proposed integrated framework, which aims to give guidance in developing research methods, which are more socially responsive. Having shown the usefulness of the proposed research framework, the thesis recommends that public policy interventions (at national and local levels) should aim to eliminate all types of institutions which have high associated transactional costs. The interventions should also encourage the emergence and growth of the types of institutions, which present the lowest costs to initiatives of economic development. In the primary case studies from the Eastern Cape Province, the insecurity of land tenure and the various local initiatives of business ventures are highlighted as two examples of the types of institutions, which respectively present high and low transactional costs to local initiatives of agricultural and economic development.

A comparison between the South African "source rules" in relation to income tax and the "permanent establishment rules" as contained in double taxation agreements

- Description: South Africa's right to tax the income of a non-resident is determined in terms of the South African "source rules" established by court decisions in relation to the imposition of tax in terms of the Income Tax Act. Unless a non-resident's income is captured by the South African "source rules" (on the basis that hi slits income is derived from a South African source), South Africa would have no right to tax such income, even if such non-resident creates a permanent establishment in South Africa by performing business activities within South Africa which could be considered essential (but not dominant) in nature. In such scenario the activities performed by the non-resident in South Africa may utilise the natural resources and the infrastructure of South Africa, but the South African fiscus would be deprived of the right to any tax revenues attributable to the income produced partly by such activities within South Africa. The South African "source rules" refer only to the main or dominant activities giving rise to the income for the purpose of determining the source of such income (and accordingly the right to tax such income). On the other hand, the "permanent establishment rules" as set out under the Organisation for Economic Cooperation and Development Model Tax Convention on Income and on Capital refer to all the taxpayer's essential business activities for the purpose of determining whether or not such activities create a pennanent establishment. The result of the narrow nature of the South African "source rules" is that, under certain circumstances, the South African fiscus would not necessarily be granted the right to tax all income produced partly within South Africa. The research demonstrated that incorporating the principles underlying the "pennanent establishment rules" into South African legislation would be a reasonable and logical solution to the problem of detennining the source of income. In so doing, the South African "source rules" would determine the source of income, and consequently South Africa's taxing rights, with reference to the essential business activities giving rise to such income. In such case South Africa would be afforded the right to tax the income of a non-resident in the event that it performs any of its essential business activities within South Africa, albeit not the dominant or main activities giving rise to the income.

- Description: his study builds on South African cross-cultural research which demonstrated the importance of careful stratification of multicultural/multilingual normative samples for quality of education in respect of English and African language (predominantly Xhosa) speaking adults and children tested with the WAIS-III and WISC-IV, respectively. The aim of the present study was to produce an expanded set of preliminary comparative norms on the WISC-IV for white and coloured Afrikaans, white English and black Xhosa speaking Grade 7 children, aged 12 to 13 years, stratified for advantaged versus disadvantaged education. The results of this study replicate the findings of the prior South African cross-cultural studies in respect of quality of education, as groups with advantaged private/former Model C schooling outperformed those with disadvantaged former DET or HOR township schooling. Furthermore, a downward continuum of WISC-IV IQ test performance emerged as follows: 1) white English advantaged (high average), 2) white Afrikaans advantaged and black Xhosa advantaged (average), 3) coloured Afrikaans advantaged (below average), 4) black Xhosa disadvantaged (borderline), and 5) coloured Afrikaans disadvantaged (extremely low). The present study has demonstrated that while language and ethnic variables reveal subtle effects on IQ test performance, quality of education has the most significant effect – impacting significantly on verbal performance with this effect replicated in respect of the FSIQ. Therefore caution should be exercised in interpreting test results of individuals from different language/ethnic groups, and in particular those with disadvantaged schooling, as preliminary data suggest that these individuals achieve scores which are 20 – 35 points lower than the UK standardisation.

- Description: The media, which help define what we think and our roles in the society, have a crucial role to project both men and women’s issues so as to change people’s perceptions and stereotypes about the role men and women play in the society. There is need, therefore, to ensure gender equality in the operations of the media so that issues to do with both men and women get adequate and equal coverage. This study on the reportage of the land redistribution exercise in Zimbabwe has, however, exposed the gendered nature of the operations of the media, particularly in the news production process. It provides that, overally, the news discourse is a masculine narrative whose androcentric form is a result of, and is protected by, claims to ‘objectivity,’ ‘professionalism’, ‘impartiality’ and the pursuit of a journalistic routine system that hegemonically prioritises men’s issues over those of women. The situation, as the research shows, has not been helped by journalists’ incapacity to do thematic appreciation of issues and their over-inclination towards a simplistic event-based journalism that fails to question policies as they are enacted and implemented in gender-skewed processes. The lack of gender policies, the operations of patriarchy and the pursuit of a journalistic routine system that sees nothing wrong with the ostracisation of women issues are very fundamental findings that the research uses in its attempts to explain why the gender equality discourse was left out of the news reports about the land reform exercise in Zimbabwe.

A feasibility study into total electron content prediction using neural networks
- Authors: Habarulema, John Bosco
- Date: 2008
- Subjects: Electrons , Neural networks (Computer science) , Global Positioning System , Ionosphere , Ionospheric electron density
- Language: English
- Type: Thesis , Masters , MSc

- Description: Global Positioning System (GPS) networks provide an opportunity to study the dynamics and continuous changes in the ionosphere by supplementing ionospheric measurements which are usually obtained by various techniques such as ionosondes, incoherent scatter radars and satellites. Total electron content (TEC) is one of the physical quantities that can be derived from GPS data, and provides an indication of ionospheric variability. This thesis presents a feasibility study for the development of a Neural Network (NN) based model for the prediction of South African GPS derived TEC. The South African GPS receiver network is operated and maintained by the Chief Directorate Surveys and Mapping (CDSM) in Cape Town, South Africa. Three South African locations were identified and used in the development of an input space and NN architecture for the model. The input space includes the day number (seasonal variation), hour (diurnal variation), sunspot number (measure of the solar activity), and magnetic index(measure of the magnetic activity). An attempt to study the effects of solar wind on TEC variability was carried out using the Advanced Composition Explorer (ACE) data and it is recommended that more study be done using low altitude satellite data. An analysis was done by comparing predicted NN TEC with TEC values from the IRI2001 version of the International Reference Ionosphere (IRI), validating GPS TEC with ionosonde TEC (ITEC) and assessing the performance of the NN model during equinoxes and solstices. Results show that NNs predict GPS TEC more accurately than the IRI at South African GPS locations, but that more good quality GPS data is required before a truly representative empirical GPS TEC model can be released.

A global study of forensically significant calliphorids: implications for identification
- Harvey, M L, Gaudieri, S, Villet, Martin H, Dadour, I R

- Description: A proliferation of molecular studies of the forensically significant Calliphoridae in the last decade has seen molecule-based identification of immature and damaged specimens become a routine complement to traditional morphological identification as a preliminary to the accurate estimation of post-mortem intervals (PMI), which depends on the use of species-specific developmental data. Published molecular studies have tended to focus on generating data for geographically localised communities of species of importance, which has limited the consideration of intraspecific variation in species of global distribution. This study used phylogenetic analysis to assess the species status of 27 forensically important calliphorid species based on 1167 base pairs of the COI gene of 119 specimens from 22 countries, and confirmed the utility of the COI gene in identifying most species. The species Lucilia cuprina, Chrysomya megacephala, Ch. saffranea, Ch. albifrontalis and Calliphora stygia were unable to be monophyletically resolved based on these data. Identification of phylogenetically young species will require a faster-evolving molecular marker, but most species could be unambiguously characterised by sampling relatively few conspecific individuals if they were from distant localities. Intraspecific geographical variation was observed within Ch. rufifacies and L. cuprina, and is discussed with reference to unrecognised species.

- Description: Typically, the configuration of audio hardware and software is not integrated. This paper discusses a software system that has been developed to remotely control and recall the properties of IEEE1394 (FireWire) audio devices via a series of graphical routing matrices. The software presents sound engineers with a graphical routing matrix that shows, along its axes, the available FireWire audio devices on a FireWire network. Inter device connection management may be performed by selecting the cross points on the grid, and intra device control may be performed via device editors that are displayed via the axes of the matrix. The software application may be hosted by a compatible Digital Audio Workstation (DAW) application to allow for the storing and recalling of the various properties associated with the devices.
