The fitting problem in a lattice Universe - Larena, J.
We present a regular cubic lattice solution to Einstein field equations
that is exact at second order in a small parameter. We show that this solution
is kinematically equivalent to the Friedmann-Lemaˆıtre-Robertson-Walker (FLRW)
solution with the same averaged energy density. This allows us to discuss the fitting
problem in that framework: are observables along the past lightcone of observers
equivalent to those in the analogue FLRW model obtained by smoothing spatially
the distribution of matter? We find a criterion on the compacity of the objects that
must be satisfied in order for the answer to this question to be positive and given
by perturbative arguments. If this criterion...
Futures Studies for the southern African region: ‘from Africa’ not ‘on Africa’ - Fox, R.C.; Rowntree, Kate; Kaskinen, J.
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...
Guy Butler’s South Africanism: ‘Being present where you are’ - Wright, L.S.
Guy Butler (1918-2001) has been gone some ten years. The institutions he created continue to make vital contributions in South Africa’s efforts to make sense of its own complex cultural and historical make-up. However, despite this evident success, there is little surety that the rationale informing his massive effort to foster processes of artistic and cultural endeavour has been appreciated or accurately understood. This lecture sets out to illuminate the thinking behind Butler’s important contributions to South Africa’s national life.
Role Playing African Development: an International Comparison - Fox, R.C.; Assmo, P.; Kjellgren, H.
The African Development Game is a role playing simulation developed to demonstrate the difficulties six African countries face in reaching the Millennium Development Goals. The game has been played in three different countries, South Africa, Sweden and Finland, to examine its utility as a learning tool for students who are unfamiliar both with the Millennium Development Goals and the problems of African development. Analysis of the games played in South Africa and Sweden. is based on a comparison of student reflections supplemented by participant observation and spreadsheet information of economic performances. Marked differences in the types of learning and success...
Active Learning for Understanding Land Degradation: African Catchment Game and Riskmap - Rowntree, Kate; Fox, R.C.
Land degradation is the result of the intersection of a complex set of biophysical and socio-economic factors. The capacity of an individual or community to address land degradation is likewise constrained. While it is quite possible for professionals and learners to grasp the main issues around land degradation from a theoretical perspective, internalizing the reality of what it means to be the resource degrader is more difficult. We have developed two active learning methods that aim to address this problem. The first is the African Catchment Game, a role-playing game based on Graham Chapman’s Green Revolution Game, adapted for the...
On the Fast Track to Land Degradation? A Case Study of the Impact of the Fast Track Land Reform Programme in Kadoma District, Zimbabwe - Fox, R.C.; Rowntree, Kate; Chigumira, E.C.
The Fast Track Land Reform Programme is the defining instrument for Zimbabwe’s future development prospects. In the three year period from 2000 to 2002 300,000 families were resettled on 11 million hectares thus witnessing the end of the colonial division of land which had seen 15.5 million hectares still in European hands in 1980, the start of the post-colonial period. The process which displaced the commercial farm workers and farm owners was chaotic, violent and disorderly and so has been called jambanja. Subsequent legislation and government agricultural initiatives have attempted to impose, retroactively, technocratic order to the sweeping changes that...
LibQUAL+™ at Rhodes University Library: An Overview of the First South African Implementation - Moon, A.E.
When Rhodes University Library closed its LibQUAL+™ survey on 29 August 2005, it became the first of seven university libraries in South Africa to complete this Web-based survey, which measures library users’ perceptions of service quality and identifies gaps between desired, perceived, and minimum expectations of service.
This paper focuses on the Rhodes Library’s implementation of the 2005 LibQUAL+™ survey. Results are looked at within the broader context of aggregate scores and score norms from the South African cohort. The library’s first efforts to address areas where perceptions of service quality differed from users’ expectations are described and plans for future...
