Description: Spiders were sampled at Mpala Research Centre, Laikipia, Kenya using pitfall trapping and sweep netting. Sampling was conducted from May 2001 to July 2002. A total of 10,487 individuals from 132 species belonging to 30 families were recorded. The family Salticidae had the highest number of species (24), followed by Gnaphosidae (20), Araneidae and Lycosidae (15 each), Theridiidae and Thomisidae (8 each) and Zodariidae (4). Most of the other families had fewer than 4 species. Throughout the study period, species not previously sampled emerged after rainfall peaks. Many species are apparently undescribed, highlighting the inadequate documentation of these taxa in Kenya. We suggest that the spider fauna of black cotton soil habitats is rich and useful for environmental monitoring, that further surveys using other collecting methods are needed, and that support for the conservation of this ecosystem should be continued. The study once more reveals the urgent need for taxonomic studies on Kenyan invertebrates.

Description: One major aspect of research in forensic entomology is the investigation of molecular techniques for the accurate identification of insects. Studies to date have addressed the corpse fauna of many geographical regions, but generally neglected the southern African calliphorid species. In this study, forensically significant calliphorids from South Africa, Swaziland, Botswana and Zimbabwe and Australia were sequenced over an 1167 base pair region of the COI gene. Phylogenetic analysis was performed to examine the ability of the region to resolve species identities and taxonomic relationships between species. Analyses by neighbour-joining, maximum parsimony and maximum likelihood methods all showed the potential of this region to provide the necessary species-level identifications for application to post-mortem interval (PMI) estimation; however, higher level taxonomic relationships did vary according to method of analysis. Intraspecific variation was also considered in relation to determining suitable maximum levels of variation to be expected during analysis. Individuals of some species in the study represented populations from both South Africa and the east coast of Australia, yet maximum intraspecific variation over this gene region was calculated at 0.8%, with minimum interspecific variation at 3%, indicating distinct ranges of variation to be expected at intra- and interspecific levels. This region therefore appears to provide southern African forensic entomologists with a new technique for providing accurate identification for application to estimation of PMI.

Description: Over the past few months, the Namibian labour movement - particularly the country’s largest trade union federation, the National Union of Namibian Workers (NUNW) - has been the subject of debate and media attention. Contradictory statements by union leaders, the NUNW’s position on the elections in Zimbabwe and the federation’s role in the privatisation of Air Namibia have raised serious questions about the vision and mission of Namibian trade unions. This article hopes to shed some light on recent developments against the background of the ongoing challenges facing the labour movement since independence.

Economic security and the social science literature on teenage pregnancy in South Africa

Description: Feminists have argued that the association made between teenage childbearing and long-term lower socioeconomic status hides a multitude of socially constructed inequalities. I extend this position by analysing how the association is linked in the South African literature on teenage pregnancy to economic security. I utilise Foucault’s conceptualization of the method of security. Security refers to institutions and practices that defend and maintain a national population as well as secure the economic, demographic, and social processes of that population. I analyse how the traits of the method of security are deployed with regard to teenage pregnancy; how reproductive adolescents are viewed as disrupting the production of the economic self and fracturing population control, thereby threatening economic security; and how the invocation of economic security allows for the legitimation of various regulatory practices. , Rhodes University

Description: Thirty seasoned foot-soldiers were exposed to a total of 16 combinations of marching speed and backpack load, each soldier experiencing 8 of the combinations between 3.5km.h-1 with a 20kg load and 6.5km.h-1 with a 65kg load. Detailed physiological analyses were conducted, of which the heart rate responses are reported here. Steady state was achieved with all combinations under 5.5km.h-1 speed and 35kg load. Excessively elevated heart rates were elicited by all loads over 20kg at 6.5km.h-1 marching speed; by loads over 35kg at 5.5km.h-1 marching speed and by the 65kg load even at 4.5km.h-1 marching speed.

Description: After many deadlocks, accusations of negotiating in bad faith, marches and lunch-time pickets, more than 600,000 Public Sector Workers went on strike on 24 August 1999. The government then unilaterally implemented a 6.3% increase for public servants against their original demand of 10-15% increase. "The dispute goes back to January 1999, to a workshop dealing with the budgetary process. At this meeting the Department of Finance outlined its Medium-Term Expenditure Framework, for the first time to the public sector workers. In the MTEF the parameters for wage cuts, and 'non-negotiability’ were already set. All unions in the public service bargaining council presented their wage demands - 10% to 15%” [COSATU paper on Public Sector Workers Fight for a Living Wage.] Thereafter COSATU and government officials met over the next few months until May 1999, when a dispute was declared. On the 29th March 1999, COSATU commented ‘To the Unions it is clear, government is not prepared to negotiate - it has already made up its mind’ [COSATU document - Public Sector Workers Fight for a Living Wage] During the period May-June COSATU Unions decided to “throw their weight behind the ANC election campaign.’’[ibid.]. By the August 1999 the unions compromised their demand from 10% to 7.3% increase. Towards the end of August the government unilaterally implemented ei 6.3% increase for public sector workers, and 4% increase for itself. It then went on an ideological media campaign against the workers claiming that the 4% increase for members of parliament is much less than what has been granted to the public sector workers. , Vol. 5 no. 3

Description: The SAMWU anti-privatisation campaign goes right to the heart of all members in their role as service providers to the community. Any privatisation of municipal services would mean that people in community not have access to basic services. It would also mean a loss of jobs through retrenchment and restructuring. This has already happened in other parts of the world. Internationally, public sector unions are fighting privatisation. For all these reasons, SAMWU calls on all members to intensify the anti-privatisation campaign! Experiences internationally have shown that privatisation results in increase in tariffs and a decline in quality services. Our communities have never received a quality service under apartheid. Now things will even be worse: under privatisation only those who can afford to pay, will get services. A major political responsibility that confronts SAMWU: we must ensure that we win the struggle against privatisation. We are confident that based on the democratic participation of ‘our gold', SAMWU workers, COSATU and the community we can be victorious.

Description: Since the publication of the previous edition of this book there have been considerable developments and controversy in the field of topical corticosteroid bioequivalence assessment. There has been considerable discussion in the literature concerning the use of the Minolta chromameter for the measurement of corticosteroid-induced skin blanching, as it is believed this instrument would produce more objective results than the visual grading procedure. These efforts culminated in the release of a guidance document from the Food and Drug Administration (FDA) detailing the procedures to be followed for the determination of topical corticosteroid bioequivalence using the chromameter. Since the promulgation of this document there have been challenges on the validity and scientific merit of the documented procedures, and recently the FDA itself conceded that it may be necessary to redefine some of the protocol evaluations. This chapter attempts to redefine the current standing of the two methods of response assessment.

Description: The Marinkas Quellen Carbonatite Complex, in southern Namibia, forms part of the ca. 490–550 Ma Kuboos-Bremen Igneous Province, a zone of alkaline igneous rocks that intrude the Mesoproterzoic to Paleoproterozoic Namaqualand Metamorphic Province and Neoproterozoic platform sediments. The carbonatite complex includes Ca-rich, Mg-rich and Fe-rich carbonatites as well as late ferrocarbonatite dykes that show extreme enrichments in Mn, REE and Th. Compared to most carbonatites, those at Marinkas Quellen are generally depleted in most trace elements, particularly Ba and the LREE.
