- Description: The nationwide strike by 70 000 construction workers between 8 and 15 July 2009 was unprecedented and significant in several respects. This was the first national strike on 2010 World Cup sites by South African construction workers and was therefore an historic event. A second key feature of the strike was the unity displayed by workers and trade unions within a sector organised by several trade unions. Engineering and building workers came out on strike, with the Building Construction & Allied Workers Union (BCAWU) and the National Union of Mineworkers (NUM) standing together as their representative organisations. A third feature of the strike was the widespread sympathy for it by the South African public and media. This was despite it potentially setting back progress with World Cup projects. Fourthly, the pressure placed upon the trade unions' negotiating team by the Ministry of Labour and the FIFA Local Organising Committee (LOC) proved lethal in undermining their, assisting in causing them to dilute their trade union demands and demobilising the national strike.

- Description: Common carp (Cyprinus carpio) is one of the world’s most widely introduced and established freshwater fishes (Casal 2006). The species is considered to be one of the eight most invasive freshwater fishes (Lowe et al. 2000) and worldwide, it accounts for most of the records of successful establishments and adverse ecological effects (Casal 2006; Kulhanek et al. 2011). This invasive success suggests that feral C. carpio is equipped with a set of adaptable life history attributes that allow it to successfully colonise a wide range of habitats (Koehn 2004; Zambrano et al. 2006; Britton et al. 2007). Where feral C. carpio occurs in high densities, it is often perceived as an invasive pest species (Sivakumaran et al. 2003; Brown and Walker 2004; Koehn 2004) because it can have severe impacts on habitat heterogeneity and biodiversity by increasing water turbidity through its bottom feeding behaviour, increasing nutrient availability, decreasing benthic and macrophyte density and diversity, altering zooplankton assemblages and decreasing endemic fish abundance (Zambrano et al. 2001; Khan 2003; Kulhanek et al. 2011). Within south-east Australia, for example, C. carpio comprises the largest proportion of the ichthyobiomass in the continent’s largest river system – the Murray–Darling Basin (Gehrke et al. 1995). As a consequence, serious concerns about its threat to endemic freshwater species (Koehn 2004) have prompted several of the most recent investigations into its life history (e.g. Sivakumaran et al. 2003; Smith and Walker 2004; Brown et al. 2005). Other potential threats posed also include competition with indigenous species and the spread of diseases and parasites (Dudgeon et al. 2006). In South Africa, for example, Asian tapeworm Bothriocephalus acheilognathi is now widely distributed in seven river systems and has infected eight novel cyprinid hosts due to the translocation of infected by C. carpio from a centralized aquaculture facility (Stadtlander et al. 2011).

- Description: The Mkuze Wetland System, forming part of the iSimangaliso World Heritage Site, is South Africa’s largest freshwater wetland area and is known to act as a sink for naturally occurring solutes within the landscape. The chemistry of groundwater and porewater samples, collected from two transects on the Mkuze River floodplain, was investigated to identify processes involved in the control of solute concentrations. Results show that solutes in the groundwater become increasingly concentrated under the influence of evapotranspiration, resulting in the saturation, precipitation, and accumulation of less soluble compounds.

- Description: Theiler’s murine encephalomyelitis virus (TMEV) is a positive-sense RNA virus belonging to the Cardiovirus genus in the family Picornaviridae. In addition to other host cellular factors and pathways, picornaviruses utilise heat shock proteins (Hsps) to facilitate their propagation in cells. This study investigated the localisation of Hsps 70 and 90 in TMEV-infected BHK-21 cells by indirect immunofluorescence and confocal microscopy. The effect of Hsp90 inhibitors novobiocin (Nov) and geldanamycin (GA) on the development of cytopathic effect (CPE) induced by infection was also examined. Hsp90 staining was uniformly distributed in the cytoplasm of uninfected cells but was found concentrated in the perinuclear region during late infection where it overlapped with the signal for non-structural protein 2C within the viral replication complex.

- Description: The burgeoning worlds of massively multiplayer online role-playing games (MMORPG) coupled with increasing access to the internet is opening a new paradigmatic window for a number of disciplines. Many of these have been slow to take up the challenges associated with this emergent framework, due, in no small measure, to the perception that work and play are mutually exclusive. The dominance of this dichotomy contributed to the slow uptake of the potential for these virtual worlds to be harnessed in the fields of education and employment. This reticence was due in no small measure to the technophobia that tends to characterise the adoption of new technologies within fields that have customarily eschewed an embrace.
