Creating virtual communities of practice for learning technology in higher education: Issues, challenges and experiences

The need for a Web portal to support the rapidly growing field of learning technology has been well established through a number of national surveys and scoping studies over recent years. The overarching vision has been the provision of a virtual environment to assist in informing and developing professional practice in the use of learning technologies. This paper outlines the issues and challenges in creating such a portal through the experiences of developing the RESULTs Network. In the paper, design and participation issues are considered within the wider context of online and networked approaches to supporting practice and professional development. User participation methodologies and technical developments for RESULTs are described in relation to a review of existing representations of practice and a comprehensive survey amongst the learning technology users’ community. An outline of key achievements and experiences is presented, followed by some conclusions regarding the cultural and political issues in creating a viable and sustainable facility and suggestions for possible future direction in national provision

The north Randfontein Chinese Miners' 'Strike' of 1905

African Studies Seminar series. Paper presented July 1975On the 1st April 1905, on the North Randfontein gold-mine in the Transvaal, a simmering dispute between the Chinese Indentured labourers and the mine management erupted in open violence. The whole of the Chinese work force on the mine premises was involved and mounted European police were used to quell the outbreak. As a result of this incident, described by the Conservative Colonial Secretary as a dangerous dispute over wages, fifty-three Chinese were arrested and charged with public violence and assault with intent to do harm. Following these arrests the Chinese returned to work. On the 4th April, however, they received a wage offer which formed not only the basis of the settlement at the North Randfontein, but was to serve as a model upon which the Transvaal Chamber of Mines based its wage policy towards all Chinese, for the latter's remaining period on the Rand

Intermodal Four-Wave-Mixing and Parametric Amplification in km-long Fibers

We theoretically and numerically investigate intermodal four-wave-mixing in km-long fibers, where random birefringence fluctuations are present along the fiber length. We identify several distinct regimes that depend on the relative magnitude between the length scale of the random fluctuations and the beat-lengths of the interacting quasi-degenerate modes. In addition, we analyze the impact of polarization mode-dispersion and we demonstrate that random variations of the core radius, which are typically encountered during the drawing stage of the fiber, can represent the major source of bandwidth impairment. These results set a boundary on the limits of validity of the classical Manakov model and may be useful for the design of multimode parametric amplifiers and wavelength converters, as well as for the analysis of nonlinear impairments in long-haul spatial division multiplexed transmission
