- Description: preprint , This book is a primarily a study of Charles Kean’s productions of Shakespeare’s English chronicle plays at the Princess’s Theatre between 1852 and 1859, a period crucial to the development of ideas of English nationalism. Schoch focuses on these particular stagings as more than drama; as performances of nineteenth century theories of history and historical representation. His project operates under the aegis of the so-called ‘linguistic turn’ in cultural theory, and is suspicious of neo-marxian fundamentalism.

- Description: preprint , There can be few shows that test the dimensions and pitfalls of 'globalised' theatre as thoroughly as Welcome Msomi's Umabatha. The worldwide success of the show, in box-office terms, can hardly be argued with. And yet, in its very conception, the vehicle is so riven by intrinsic cultural, theatrical, class and 'nationist' tensions that different audiences cannot but reap utterly different experiences, depending on their own cultural and intellectual inheritance.The show is an instance where theatre practice (sometimes) obfuscates political and aesthetic discourse, showing how easily cultures miss each other and fail to connect, and how easily specific historical, geographical and imperial associations are swamped by shallow 'globalised' audience response.

- Description: An amperometric sensor, based on carbon paste impregnated with iron (II) phthalocyanine complex (FePc), has been constructed for the assay of anti‐HIV agent dideoxyinosine (didanosine, DDI). Using chronoamperometry (E = +1.04 V versus Ag/AgCl) technique, the amperometric sensor can be used reliably for dideoxyinosine assay at pH 7.4 phosphate buffer in the 1.5–9.5 nmol/L concentration range with a detection limit of 5.7 × 10−10 mol/L. The surface of the electrode can easily be regenerated by simple polishing, obtaining a fresh surface ready for use in a new assay. The new amperometric sensor proved to be highly reliable for the assay of dideoxyinosine purity in raw material as well as for the uniformity content test of Videx® tablets.

More media for Southern Africa?: the place of politics, economics and convergence in developing media density

- Description: In line with global trends, media in Southern Africa in the past decade has been moving slowly towards mergers, partnerships and multi-platform publishing. Driven by politics and facilitated by technology, the process has had to confront the difficulty of establishing viable economic models, the lack of regional integration within Southern African countries, and what is sometimes a difficult political environment. Markets remain largely national or local and economically weak. Print media faces huge hurdles. Broadcast media density is improving, partly through noncommercial mechanisms. News websites are understaffed, lacking in viable survival strategies and skills, and are incompletely integrated with parent media platforms. Economic pressures, however, are likely to force Southern African media operations into greater synergies in search of survival. The various convergences entailed may increase media density.

- Description: Probiotics for aquaculture are generally only selected by their ability to produce antimicrobial metabolites; however, attachment to intestinal mucus is important in order to remain within the gut of its host. Five candidate probiotics (AP1–AP5), isolated from the clownfish, Amphiprion percula (Lacepéde), were examined for their ability to attach to fish intestinal mucus and compete with two pathogens, Aeromonas hydrophila and Vibrio alginolyticus. Two different radioactive isotopes were used to quantify competition between pathogens and probionts. Attachment of the pathogens was enhanced by the presence of the candidate probiotics. However, the addition of the candidate probiotics after the pathogens resulted in reduced pathogen attachment.

- Description: Spectral properties of metallophthalocyanines and other tetraazaporphyrins are governed mainly by the Q band which originates from the π-π* transitions within the ring. The position and intensity of the Q band is important in tailoring new phthalocyanine derivatives for particular applications. Aggregation, the nature of the central metal, π conjugation, symmetry of the molecules, and axial, peripheral or non-peripheral substitutions affect the spectra and hence the properties of the phthalocyanine molecule. This review gives a brief outline on how optical spectroscopy provides useful informations on molecular and electronic structures, chemistry and physics of phthalocyanines and other tetraazaporphyrins.

- Description: Surveys of trade in wildlife products utilised in traditional medicine were conducted between 1997 and 1999 on the western boundary of the Kruger National Park, South Africa. Although the extent of trade and numbers of people operating in this sector were lower than other regions of South Africa, this study again highlighted the value of indigenous wildlife products to subsistence economies. Apart from cultural diversity, socioeconomic differentiation occurred at a number of levels. (i) There were socio-economic differences between the traders and vendors. (ii) Gender differences were apparent, with women earning significantly less than men and having to undergo more social challenges in their operation in the market place. (iii) Operational differences were noted between the vendors and traders, as well as between the street and pension day vendors. (iv) Multidimensional Scaling (MDS) highlighted the socio-economic differentiation at the household level, emphasizing in particular one of the most vulnerable groups, the elderly. The potential influence of this socio-economic differentiation needs to be considered during the development of Community-Based Conservation programmes, if the dual aims of conserving biodiversity and improving the lives and livelihoods of those who traditionally rely on medicinal plants are to be met.

- Description: preprint , It is rare for a writer to make a literary impact with only one novel. It is even more unusual when that work is written by a novice author in his early sixties. Yet such is the case of R.L. Peteni, whose novel, Hill of Fools, was published by David Philip in South Africa in 1976, and internationally in the same year by Heinemann in the African Writers Series. Four years later, in 1980, the book was translated by the author into Xhosa as Kwazidenge and published by the Lovedale Press. Twenty years after initial publication, in 1996, there came a television version of Kwazidenge broadcast by the SABC, starring Willie Thambo and Amanda Quwe, though the locale was translated – in the bizarre logic of television – to an urban environment on the Cape Flats. The transposition, though pragmatic in terms of television demographics, destroyed much of the point of Peteni’s work, for Hill of Fools is South Africa’s first regional novel in English by a black writer. It is also the first novel in English by a Xhosa-speaker.

- Description: Publisher version , Introduction: Contributors to the prostitution/sex work debate, whether they condone, support or oppose criminalisation, legalisation or decriminalisation of prostitution, often rely on ‘facts’ to support their arguments. A common fact is that the majority of prostitutes/sex workers in the world and in South Africa are women. Thus, when I refer to prostitutes/sex workers, I refer to women working as prostitutes in the commercial sex industry. Furthermore, the fact that the majority of sex workers are women justifies considering prostitution from a feminist perspective – women’s voices on the subject should be heard. In this note I shall use the terms ‘prostitution’ and ‘sex work’ to refer to the exchange of sexual services for money. The former, more conventional term has a negative connotation, while the term ‘sex work’ denotes a movement away from casting a moral judgment towards recognition that sex work is just another job. References will be made to the associated activities of brothel-keeping and pimping, but the focus of this note is mainly on the provision of sexual services by the prostitute/ sex worker herself. Jordan v S is a Constitutional Court judgment in which the constitutional validity of the criminalisation of prostitution and its related activities were challenged. In order to analyse this judgment from a feminist perspective, I shall first briefly set out the current legal position on prostitution. Thereafter, I shall give an overview of Western feminist perspectives on prostitution and then link this perspective with African feminism. The last part of the note will be an analysis of the Jordan judgment in light of the feminist perspectives identified before.

Three decades of hydrological modelling research in South Africa

- Description: This paper presents a review of the research undertaken in the field of hydrological modelling over roughly the last three decades, concentrating primarily on South African work in an international context. The focus is on deterministic, rainfall-runoff models and addresses issues related to model design as well as to the application of models in practice. I provide a brief description of what hydrological models are and what they are used for and discuss also the following issues: • Developments in understanding hydrological process and the extent to which these have filtered down into models. • Model calibration and parameter estimation. • Trends in data availability and how these have affected model development. • Trends in computer technology and their impacts on model development. I suggest that there have been substantial developments in the science and practice of hydrological modelling, but that there remain many problems that need to be addressed to improve the ability of models to contribute to the solution of problems of water resource management. Southern African scientists have contributed to the body of knowledge on hydrological modelling, despite the limited resources available compared to resources elsewhere. Internationally, the focus has not always been on the practical issues of model application and has commonly tended towards the more theoretical and mathematical issues of model calibration. This is not a trend that has found much favour in southern Africa (particularly amongst research funding agencies), where there are many problems of water resource management that have the potential to be resolved with existing models, applied in an appropriate way. The paper concludes by suggesting that further research needs to focus on the integration of the best in international developments with the tried and tested models that have been developed locally. The context of this research should be the search for more reliable estimations of water resource availability.

The first reduction and oxidation in this complex occur at the central metal, giving CrIITAPc and CrIVTAPc complexes, respectively, the latter having been observed for the first time. The CrIIITAPc species was polymerized onto glassy carbon (GCE) or indium tin oxide (ITO) electrodes and the polymer evolution confirmed by UV/Visible spectroscopy and by scanning electron microscopy. The polymers were employed for the catalytic oxidation of nitrite or nitric oxide, and the catalysis involved the CrIVTAPc−1 species.

The fuelwood crisis in southern Africa: Relating fuelwood use to livelihoods in a rural village

- Description: The aim of the paper is to examine wood as a source of fuel energy in rural South Africa and factors influencing its usage. The analysis is based on household profiles and characteristics (e.g., gender, caste, population and income) in a livelihood framework. Fuelwood consumption was estimated to be 692 kg/capita, and 4343 kg/user household per annum, valued at $311 per household. Consumption was modelled in relation to informal and formal cash incomes, and population of children, female and male adults. However, only the population of female adults could significantly influence consumption of fuelwood. This implied that where there were more women in a household, consumption was likely to be high. This might be due to the majority of women doing the cooking and heating in the household. Any change in the value of cash income of households had no significant impacts on fuelwood consumed. Cash incomes might therefore not be strong determinants of the types of energy used by rural households. The average quantity of wood consumed for fuel energy in summer was not significantly different from consumption in winter. Some households perpetually used more wood than others. The study further showed that harvesting of wood for fuel energy is not opportunistic, but requires reallocation of time for other livelihood activities in times of shortage. The fuelwood crisis is not simple and not only about shortage of fuelwood and/or population growth but linked to household profiles and other livelihood strategies and subsequently vulnerability of households. These would require thorough investigation and understanding in relation to precise demand and supply data for fuelwood before the fuelwood problem can be sufficiently managed.

- Description: Interactivity is a distinguishing feature of the online environment but online newspapers have been slow in recognising interactivity as an essential condition of effective Web communication. Existing research show online newspapers generally offer few and token interactive options. This research explored interactivity in online journalism using Nigeria's online Guardian as a case study exploring the nature, levels and utilisation of interactivity and interactive features on the site. This study found that few interactive options are offered in Nigeria's online Guardian and those interactive options on offer just produced an illusion of interactivity; it was apparent that little effort was made to give interactive options on the site the significant attention they deserve. The study highlighted the difference between the availability and use of interactive features on an online newspaper site: the mere presence of such features does not necessarily speak to the levels or nature of interactivity on the site. The difficulty in obtaining findings for the qualitative aspect of this study spoke significantly to the findings in light of the fact that these were attempts using interactive options provided by the newspaper site. They stress what relevant literature highlights: the mere presence of interactive features is not in itself interactivity . Factors contributing to the low levels of interactivity in Nigeria's online Guardian include lack of technical expertise plus human and financial resources and the persistence of a mindset that hinders the development and integration of new information communication technologies and interactivity in online journalism. Theoretically, the possibilities are vast but the likelihood of translating theory into reality appears slim. For Nigeria's online Guardian to become interactive in a participatory way, it must undergo changes and choices about values, goals and standards. There must be a shift in attitudes and approaches towards news-content production and delivery as well as the problematic commercial aspects of electronic publishing routines and the effect of such choices on management and newsroom organisation.

Theoretically, the possibilities are vast but the likelihood of translating theory into reality appears slim. For Nigeria's online Guardian to become interactive in a participatory way, it must undergo changes and choices about values, goals and standards. There must be a shift in attitudes and approaches towards news-content production and delivery as well as the problematic commercial aspects of electronic publishing routines and the effect of such choices on management and newsroom organisation.

- Description: Cyclohexene oxidation using tert-butylhydroperoxide (TBHP) or chloroperoxybenzoic acid (CPBA) in the presence of iron(II) polychlorophthalocyanine (Cl16PcFe), iron(II) phthalocyanine (PcFe) and cobalt(II) phthalocyanine (PcCo), results in the formation of the following products: cyclohexene oxide, 2-cyclohexene-1-ol and 2-cyclohexene-1-one. Adipic acid was also formed after long reaction times. The selectivity for 2-cyclohexene-1-one is favoured when Cl16PcFe or PcCo catalysts are employed, while PcFe is selective towards the formation of 2-cyclohexene-1-ol. The Cl16PcFe catalyst is transformed into a μ-oxo dimer (Cl16PcFeIIIOIIIFePcCl16) during the oxidation process. The catalytic process using the unsubstituted PcCoII and PcFeII catalysts involved PcMIII species as an intermediate. The active form of the Cl16PcFe catalyst was stable to degradation in that it was still active even after 4 weeks of continued catalysis.
