- 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: [From the introduction]: South Africa is a multilingual country with eleven national languages - nine indigenous languages and the two former colonial languages of English and Afrikaans1 - recognised as official languages in the Constitution of 1996 (Constitution of the Republic of South Africa, 1996). Despite these provisions, since the democratic elections of 1994 English has expanded its position as the language of access and power with the relative influence of Afrikaans shrinking, and African languages effectively confined to functions of ‘home and hearth’. McLean and McCormick (1996: 329 in Mazrui 2002: 269) suggest that the constitutional recognition of 11 official languages in South Africa is largely 'intended and perceived as a symbolic statement and that for instrumental purposes, English remains the dominant language in South Africa'.

Exploring risk related to future climates through role-playing games: the African catchment game

- Description: Risk is the result of two interacting components: hazard and vulnerability. Climatic hazards are related to extrinsic factors such as drought or severe storms. Vul- nerability is the result of intrinsic factors that often arise from the socio-political- economic context. The interplay of risk and vulnerability is difficult to predict. Although computer models have been widely used to forecast climate related risk, albeit with con- siderable uncertainty, they can never capture sufficiently the vulnerability of human sys- tems to these hazards. Role-playing games can be used more realistically to simulate pos- sible outcomes of different climate change scenarios, and allow players to reflect on their significance. The authors have developed the African Catchment Game to simulate a wa- ter scarce African country. Risk can be modelled mechanistically by changing the nature of the annual rainfall input. Vulnerability can in part be modelled by changing the start- ing parameters (such as access to land and resources) and, secondly, through the unpredictable response of players to game dynamics. Players’ reflections demonstrate that through the game they become more aware of the concept of risk and the complex response of individuals and societies that determine their vulnerability to climatic hazards. This paper reflects on the potential for developing the game further as a tool for participatory learning around climate change, based on the authors’ experience of playing the game with participants from South Africa.

An appraisal of the applicability of development journalism in the context of public service broadcasting

- Description: The concept of ‘development journalism’ has, over time, become possessed by demons of all sorts of confusion. If we want to wrest any useful principles from the concept, it is important that we exorcise the demons it has come to be associated with, not least the demon of the postcolonial state’s blatant interference in the practice of journalism. This ‘demonisation’ of the concept is partly suggested by Shah’s observation that ‘development journalism’, central to many discussions of mass communication and development in the Third World, needs to be reconceptualised because deliberations about its validity and usefulness have been bogged down in arguments structured by Western notions of press freedom. The debate has diverted attention from important questions about how journalism can contribute to participatory democracy, security, peace, and other humanistic values (Shah 1996: 143). In this paper, therefore, I will, firstly, discuss the conceptual basis of development journalism. I will rely heavily on development communication theorising, which informs most of the discussions about development journalism. I want to demonstrate the historical ‘moments’ through which the concept has passed and, by so doing, point out the more redeemable features of the concept. Secondly, I will discuss the relevance of the development journalism paradigm to public service broadcasting. In conclusion, I will draw out some principles of development journalism and demonstrate how these can be implemented within the context of public service broadcasting.

- Description: Futures studies is well established in the Nordic region and its history can be readily charted, but in Africa it barely exists in an institutional form and its evolution and impact is little known or understood. The first two sections of our paper briefly examine the history of futures studies, spending most attention on the African experience. We go on to show that the Higher Education landscape in the Southern African Development Community (SADC) region is very different to that in the Nordic region. Recent futures reports present forecasts and scenarios that show a differentiated Higher Education landscape in the SADC; there are few Higher Education Institutions (HEIs) and even the most optimistic forecasts show that the region as a whole will not meet the international enrollment norm of 30% by 2050. The last part of the paper examines our experience of collaboration with Finland and its well developed linkages between state and Universities. One outcome of three years of collaboration from 2007 to 2009 between two SANORD members, the Finland Futures Research Centre (now a part of the University of Turku) and Rhodes University, was a proposal to develop a multi-disciplinary, inter-institutional futures studies program intended to help Africa find its own voice in futures studies. The final part of our presentation reflects on the unsuccessful experiences that we have had to date in finding funding. We conclude by asking whether our experience can be seen as highlighting some of the challenges SANORD may be positioned to overcome if the SADC region’s HEIs are to achieve the Knowledge Village scenario and begin to match their Nordic counterparts.

- Description: In teaching large classes, the educationally beneficial informal interaction between students and between lecturer and students is generally reduced, while effective use of both students' and lecturer's time is often a challenge. During student consultations, especially over the already stressful test and examination periods, many of the questions asked by the students are the same or similar. The lecturer needs to respond to each query by providing the same detailed explanation for the problem, resulting in ineffective use of time for the lecturer, while students waste time waiting for an appointment, or more often, simply don't bother to follow up on any queries they may have. Having a social presence is important for students' cognitive development, but in a large class posing questions or interrogating issues during a lecture appears to be challenging for many students. It is often not easy for students to initiate discussions or establish relationships with peers or the lecturer due to feelings of vulnerability and due to the size and impersonal atmosphere of the lecture theatre. This paper deals with the introduction of online discussion forums in an introductory accounting course and the benefits and problems experienced by the students, tutors and lecturer as a result thereof. Feedback received from these participants is discussed. The introduction and use of these forums resulted in a virtual classroom being created, where significantly more teaching and learning activities took place, to the benefit of all participants. Participation could have been peripheral - in the form of simply reading discussions; or active – through posting questions, or responding to questions.

The album included a music video of the title track that calls upon the legendary Boer War general to save the volk (people) from the wantonly destructive strategies of the British imperial forces: the scorched earth policy and the subsequent internment of women and children in concentration camps. The British justified such extreme – some would say ‘genocidal’ – strategies so as to prevent non-combatants from supporting the irregular Boer soldiers. Although he did not believe that the war could be won on account of the overwhelming odds that the Boer forces faced, De la Rey still fought to the bitter end. Needless to say, he was on the losing side.

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.

- Description: This paper explores the challenges faced by small municipalities in providing water services in a developing world context of increasing urban demand. The paper uses a case study of the Sundays River Valley Municipality (SRVM) in South Africa. The municipality faces multiple dilemmas in reconciling its available water supply with growing demand for potable water in the primary urban settlement in the area, in a struggle that is typical of the broad category of South African municipalities to which the SRVM belongs. These dilemmas are explored using a system dynamics model, referred to as the ‘Kirkwood water demand system dynamics model’ (K-DEM). This paper specifically introduces the K-DEM structure,which is aimed at investigating the impacts of households progressively receiving full water and sanitation services; the use of rainwater harvesting as an alternative form of water supply; and the possible effect of a household-level water conservation / water demand management programme. Baseline results are discussed, and areas for future research identified.

- Description: The need to enhance the research profile of accounting departments and schools of accounting at South African universities and to increase the number of students engaging in postgraduate studies mirrors the challenges faced by universities in Australia and the United Kingdom two decades ago. Coupled with these imperatives is the recognition of the need for supervisor training in accounting departments and schools of accounting and the lack of opportunities for gaining experience in postgraduate research supervision due to the small number of students in the accounting field wishing to undertake research-based studies. This article reviews relevant literature on training for the supervisors of postgraduate research students, documents the personal experience and observations of the writer and, drawing on these sources, makes recommendations for the training of supervisors. The recommendations include a model for the training of supervisors reflecting two perspectives: “on-the-job” training and the introduction of a departmental supervision guide setting out aspects of best practice. Issues to be addressed in the training of supervisors include training in research methodology, technical expertise, managing the supervision relationship, quality control, providing constructive criticism and feedback, and ethical concerns.

- Description: The human skin blanching (vasoconstriction) assay has been in use for 3 decades as a tool for the assessment of the release of corticosteroids from topical dosage forms. Application of corticosteroids produces a whitening (blanching) of the skin, the intensity of which is directly related to the clinical efficacyof the formulation. Assessment of the intensity of the induced blanching has classically been, and continues to be, pe1fonned by visual grading, a method which has been criticised because of the subjectivenature of the assessment Recently there has been considerablediscussion in the literature regarding the use of the chromameter as an objective instrumental method of monitoring corticosteroid induced skin blanching for bioequivalence assessment purposes. The FDA has released a Guidance document recommending the use of the chromameter for this purpose. The chromameter measures colour in teims of three indices: the L-scale (light-dark), the a-scale (red-green) and the b-scale (yellow-blue).Any colour can be expressedabsolutelyin terms of these three values.The Guidance protocol suggests the use of only the a-scale values in quantifying the blanching response after correction of the data which includes subtraction of baseline and unmedicated site values. One of the unresolved issues in the FDA Guidance document is this method of data manipulation suggested since the instrument should be capable of assigning an absolute colour value to each site during the vasoconstriction period. The purpose of this study was to manipulate the instrumental data from a typical blanching study in a number of ways to investigate the appropriatenessof these suggested procedures.
