- Description: The African Catchment Game is an innovative role playing game which was played twice in Finland in 2008 as part of the CIMO funded collaboration between Finland Futures Research Centre and Rhodes University. It simulates a "real imaginary country" and enables participants to explore and experience how southern countries may or may not develop scenarios of sustainable resource extraction and consumption. New processes modelling climatic variability, water management and consumption were introduced for these two game runs. This imaginary country has roles for an urban/industrial sector, the informal sector, trading intermediaries, overseas trade, a government comprised of a president and two ministers, peasant and commercial farmers. Chapman's original game, Green Revolution Game/Exaction, is based on systems and complexity theories from the 1970s and 1980s. Our modifications to Chapman’s game are underpinned by theories of Complex Adaptive Systems and educational approaches based on constructivist, active/experiential learning models. The paper presents an analysis of the two Finnish games from the perspectives of the participants and the game managers. Participants’ information came from pre and post game questionnaires and the focus group discussions that were part of the debriefing pro-cess. These two methods enabled us to examine the local and network processes which de-veloped during the games. Global scale processes of production, consumption, resource utilization, trading and water provision was collected by the game managers as part of their management processes throughout each game run. Our analysis shows that the par-ticipants’ understanding altered and deepened as a result of playing the game. The nature of the game, as a Complex Adaptive System, and the constructivist learning approach through which the game is experienced means that lessons of a more universal nature cannot be extrapolated.

- Description: One of the major problems facing schools in South Africa is the difficulty in obtaining modern, up-to-date computer facilities. This paper looks at the use of open source solutions in two government schools in South Africa to demonstrate that it is possible for schools to utilise almost any existing computer to provide effective network solutions.

The biogeography of the Prosopistomatidae, with a particular emphasis on Southern African species

- Description: The mayfly family Prosopistomatidae consists of the single genus Prosopistoma Latreille. Its known distribution includes species from Africa, Madagascar, the Comores, Europe, the Levant, India, Sri Lanka, China, Vietnam, the Philippines, Malaysia, Sumatra, Java, the Solomon Islands, Papua New Guinea and northern Australia. A tropical Gondwanaland origin of the family has been suggested. No species are currently known from the Neotropical or Nearctic regions, though the family may yet be discovered in northeastern South America, since this region separated from West Africa only c.120 mya. Focussing on southern Africa, several undescribed species have recently been discovered, with interesting implications to the biogeography on a more localised scale. In the western Cape, a prosopistomatid species has been collected in the Olifants River, extending the distribution of this family further south into a more temperate region. Geological evidence indicates that the Olifants River was connected to the Orange River during the Tertiary period. Prosopistomatidae are known from the Orange River today, and the presence of the family in the Olifants River in the western Cape supports the geological evidence of the historical link between these two rivers. Another unexpected discovery was from the Buffalo River in the eastern Cape, at 33ºS. A subtropical zone extends along the east coast of South Africa as a result of the warm Agulhas current offshore, allowing the southerly extension of the distribution of more tropical species. , Research Update on Ephemeroptera & Plecoptera: Proceedings of the Tenth International Conference on Ephemeroptera, 8-11 August 2001, Perugia, Italy.

What to expect when you’re not expecting : child-freedom, social stigma, and online subjectivities

- Description: From Introduction: Today I’m presenting some of the preliminary findings of a study about voluntary childlessness conducted with Indian, Polish, and fellow South African collaborators. Voluntary childlessness is also frequently referred to as being childless by choice or childfree. The term childfree (as opposed to ‘childless’) is intended to show that not having children “can be an active and fulfilling choice”, and to indicate agency and freedom from social obligation. The distinguishing feature of voluntary childlessness is the deliberate avoidance of parenthood, and this is precisely what opens up childfree people, especially married heterosexuals, to greater stigma than the temporarily or involuntarily childless, since it is seen as willing and deliberate deviation from the norm. Having children is seen as a natural consequence of being a “normal” heterosexual woman or man, as well as an expected outcome of marriage. Parenthood is therefore normalised by regulative discourses around sexuality and gender. This process of normalisation is reinforced by pronatalist discourse. According to Meyers, pronatalism rests upon twin strategies: The first is the valorisation or glorification of parenthood, which supports the belief that having children is the only true path to fulfilment. The second strategy is the denigration of non-reproduction in which childlessness is cast as horrific. The result of these dual strategies is to eliminate deliberate childlessness as a possibility. Parenthood, as the only truly viable option for a fulfilling life, is therefore a non-choice. This is compounded by nationalistic and religious rhetoric that constructs childbearing as an obligation or duty. Consequently, as my previous research showed, people often do not reflect on whether to have children or not, but see it more as a matter of timing.
