The thesis concerns the origins, creation and progress of the International Development Research Centre (IDRC). Most scholars believe that development assistance is largely motivated by self-interest. At first glance, the Centre appears to be an anomaly in Canadian foreign aid. The IDRC's disbursements are not formally tied, has an international board of governors, and its structure was specifically designed with autonomy in mind. This Canadian federal organisation has spent one and a half billion dollars are funded over 5,500 projects since its founding in 1970. During this time, the Centre has disbursed between 70-95% of its programme funds overseas, mostly to developing country university researchers. These researchers have designed and executed research intended to help developing countries alleviate poverty, social decay and more recently, environmental challenges. / A detailed archeology is conducted of Pearson's own internationalism regarding science and technology, foreign policy, development assistance, environment and culture. Our analysis shows how Pearson's thinking, and that of colleagues who were to have key influences on the Centre, Barbara Ward and Maurice Strong, were embedded in deeply held beliefs and values. We identify a tension between an internationalist impulses and Canadian-centered or parochial pre-occupations common in most of the federal public service, especially central agencies. Central agents, responding to pressures from academics, and the internal values and beliefs that tend to form in these secretaria, have sought to make the IDRC conform to their own expectations. The author concludes that the Centre has survived and prospered, despite these pressures, partly because of the skill of its top officers, but principally because of the IDRC's capacity to lay claim to being an expression of internationalism. / We also show how another dialectic, between more socially-oriented perspectives and more technical ones affected the development of the IDRC. The thesis suggests that the two dialectics, the internationalist and parochial, and the technical and social, are both synthesising into, respectively, interdependence and holism.

This dissertation investigates the relationship of the Fortifications in Pretoria to the public. The architectural problem of making the public aware of these Fortifications is investigated and responded to by designing a Visitors centre, to draw the public to the Fort, by creating an experience of moving through the landscape. This experience orientates the visitor visually towards various other iconic monuments, by symbolically turning the visitor into a camera, capturing views and experiences for himself. The program also provides facilities for Archaeological research which will be done on various other Fortification ruins and archaeological sites in Pretoria. The visitors experience and interaction with the landscape and the vision of the Fort as artefact contributes to the visitors being made aware of the gradual deterioration of the Fortifications in the city to ruins. The Fortifications themselves are monumental ruins, but by adding to them yet still respecting their heritage qualities, makes this a sensitive and respectful response to an important problem of how to preserve historical artefacts and at the same time utilising them. West Fort will become the catalyst for public awareness and experience to the other Fortifications within the city context. / Dissertation (MArch(Prof))--University of Pretoria, 2010. / Architecture / unrestricted

Bibliography: leaves 325-341. Skin and fleece measurements were recorded at different ages for both male and female sheep from the Turretfield Merino Resource Flock and used to estimate the heritability of each trait and the phenotypic and genetic correlations among and between the skin and fleece traits. Generally, the heritability of each trait was high, which indicates that both the fleece and skin traits should respond well to selection.

Coastal erosion, population decline, and economic deterioration, in the rural coastal community of Sydney Mines, Cape Breton, are concerns upon which the provincial government is focused. This thesis explores how ideas of permanence, adaptation, and sacrifice can engage the prevailing erosion of both the coastline and community, in terms of the physical cliff face, population, and economy. Articulating methods of responding to the various conditions of erosion enables an evolving and didactic architecture, which can become a catalyst to stimulate the economy and create stability for the town. Strategies of site placement, as well as technologies of geological formation, historic mining practices, and adaptation approaches, explored in this thesis, provide examples of how prototypical architecture and programmatic insertions can create a viable solution to erosion in this coastal town.

Removing just one species from an ecosystem can have radical results. Tony Sinclair's grand-scale biodviersity knockout experiment sets out to determine why.

The research presented in this thesis has identified and developed a sophisticated computer model for the analysis of railway track dynamic behaviour to be used by the Rail Cooperative Research Centre for Railway Engineering and Technologies (Rail CRC) in Australia. To be competitive railway track owners need to extract as much performance as possible from their asset without serviceability or catastrophic failure. Railway track designers therefore need to develop more knowledge of the static and dynamic loadings that track may be subjected to in its lifetime. This would be best undertaken using computer modelling capable of quantifying the effects of train speed, traffic mix, wheel impact loading and distribution of vehicle loads into the track. A comprehensive set of criteria for the selection of a model of track dynamic behaviour was developed. An international review of state-of-the-art models which represented the railway track structure under the loading of a passing train was undertaken. The models' capabilities were assessed and a number of potential models identified. A benchmark test was initiated to compare current models available throughout the international railway research community. This unique benchmark test engaged six researchers to compare their railway track models using a set of theoretical vehicle and track data. The benchmark results showed that significantly different results may be obtained by models, depending on the assumptions of the user in representing a particular track scenario. Differing complexities and modelling methods, the number of different input parameters required and the representation of the irregularities in the wheel and rail all have effect on the results produced. As a result of these initiatives, the DARTS (Dynamic Analysis of Rail Track Structures) computer model was chosen for use by the Rail CRC. A user-friendly interface was created for DARTS by the writer, which was readily interpretable by railway design engineers. At the time of writing, DARTS was found to be suitable for detailed investigations planned by the Rail CRC for future research and was provided for use through an Intellectual Property agreement with its author.
