- Description: The shore of Lake St Lucia in the vicinity of Catalina Bay, in the southern part of the lake, receives freshwater input as surface and groundwater seepage from the adjacent elevated coastal plain. Vegetation, water quality and landform were recorded on the lakeshore and on the dry lakebed near one of these seepage zones. This was done along a gradient perpendicular to the lakeshore and along the lakeshore away from the fluvial source of freshwater input. A number of plant communities were found along a gradient of water salinity from the shoreline (fresh water) towards the centre of the lake, and also away from the fluvial input of water (increasingly saline). Species richness decreased with increasing salinity. The first study was conducted in 2006 after a prolonged drought associated with low lake levels and closure of the mouth, and repeated again in 2010 three years after breaching of the estuarine mouth by a tropical cyclone at sea, which caused inundation of the partly dry lakebed with sea water. The vegetation of the lakeshore after these major disturbances was remarkably similar in the two time periods, suggesting rapid recovery near freshwater seepage zones, following an influx of sea water.

- Description: Life Orientation sexuality education in South Africa faces many pedagogical challenges, not least among which is that it is sometimes perceived as irrelevant to learners' real interests and concerns. Learners report that the content is repetitive and that they learn more from peers than from the reiterated lessons of risk and disease avoidance that permeate sex education messages. In this article we describe the world of the study site - a 'single sex' school - as consisting of diverse informal student sexual cultures in which repertoires for the development of learner sexual identities are developed, negotiated and transmitted. The study is based on detailed ethnographic immersion in the study site which generated rich data drawn from in-depth interviews, focus groups, observations and solicited narratives. We argue that even the enlightened, tolerant 'best practice' form of sexuality education that takes place at the study site fails to take diverse learner identities, lifeworlds and experiences seriously as a pedagogic starting point, but rather tends to homogenise learners and to impose on them what they need to learn. A more empowering form of sexuality education would take seriously how young people understand themselves as sexual subjects located in unequal ('raced' and classed) social contexts.

- Description: Tony Harcup is a self-confessed ‘hackademic’, a term which he defines in his Oxford dictionary of journalism as ‘a journalist who goes on to work in journalism education where they combine the roles of journalism (hack) and academic’ (p. 121). Harcup explains that hackademics perform this balancing act in the ‘hackademy’, a curious space within academe where journalism training intersects with Journalism Studies (a field of study which is nowadays often granted ‘upper case’ status), ‘sometimes with mutual respect and insight, sometimes with mutual suspicion and hostility’ (ibid.). And this tension is never far from the surface in many of the 1 300 definitions in this useful and absorbing dictionary.

- Description: Tourism is a significant driver of social and ecological change in developing countries, particularly in small-island states, which are susceptible to tourism impacts due to their particular social and environmental characteristics. In this article we present a participatory mapping approach to obtaining spatially explicit local perceptions of future environmental and social change resulting from tourism development, as well as addressing the different community conflicts that may arise through the introduction of tourism in the future in a Solomon Islands community. The results show that spatial conflicts within a community over territory and associated resources are likely to occur when designing natural resource management and tourism development plans. This knowledge can help us increase the future sustainability of tourism in nascent small-islands destinations, particularly in vulnerable regions such as Roviana, which have experienced very little tourism development and will likely experience more in the near future.
