Cultural aspects of classroom effectiveness: Overseas-educated students in Australian classrooms

Teachers who are new to the country often find themselves as 'the stranger' in their own classroom. Languages education is one area where such overseas-educated teachers are common. The study reported here investigated what cultural factors might influence the classroom performance of such teachers. The early classroom experience of beginning Japanese native speaker teachers and trainees was examined to this end.

Cultural Specific Training in Corruption Reporting for Pacific Island Journalists

Notes that very few journalists have formal training in corruption reporting. Discusses workshops held in 2000 and 2001 on the subject of corruption reporting for Pacific Island journalists. Explains the role of the media as an anti-corruption mechanism and the difficulty journalists face in identifying and sometimes stamping out corruption. Looks at the programs adopted and explains the responses of journalists.

Modelling cement grinding circuits

Modelling and simulation studies were carried out at 26 cement clinker grinding circuits including tube mills, air separators and high pressure grinding rolls in 8 plants. The results reported earlier have shown that tube mills can be modelled as several mills in series, and the internal partition in tube mills can be modelled as a screen which must retain coarse particles in the first compartment but not impede the flow of drying air. In this work the modelling has been extended to show that the Tromp curve which describes separator (classifier) performance can be modelled in terms of d(50)(corr), by-pass, the fish hook, and the sharpness of the curve. Also the high pressure grinding rolls model developed at the Julius Kruttschnitt Mineral Research Centre gives satisfactory predictions using a breakage function derived from impact and compressed bed tests. Simulation studies of a full plant incorporating a tube mill, HPGR and separators showed that the models could successfully predict the performance of the another mill working under different conditions. The simulation capability can therefore be used for process optimization and design. (C) 2001 Elsevier Science Ltd. All rights reserved.
