ICT, EFL teacher development and the reform of college English in China: an implementation study
The purpose of this study was to investigate ICT-related EFL teacher development in the context of Chinese national College English reform. Four aims were established. First, to examine the current situation in a specific institution from the perspectives of: 1) teachers' attitudes towards ICT use in the context of College English reform; 2) the integration of ICT in English classes; 3) provision of ICT support within current continuing professional development (CPD) programmes for EFL teachers. Second, to assess the suitability of the CPD policies and practices for EFL teachers as a way of supporting the national College English reform. Third, to identify key issues affecting the effective provision of CPO in relation to ICT for EFL teachers. Fourth, to suggest possible solutions to problems identified and directions for future research. The study employed a case study involving quantitative and qualitative methods in order to give an in-depth account of the process of implementation of the reform at particular point in time. The findings indicated that initially the majority of teachers had held positive attitudes towards ICT use in English teaching and the national reform, but their enthusiasm was waning in the light of inadequate support and training. The national reform had, however, stimulated the improvement of ICT competence of both teachers and students. At the same time, it had challenged EFL teachers to adapt to new teaching materials, student-centred classroom teaching and how to guide students in their autonomous learning. In terms of ICT-related CPD policies and practices, there existed a gap between the current policies in the provision of CPD and demand for this. Recommendations are made for future research and for improvements in policy and practice of ICT-related CPD for EFL teachers in China.

Denitrification of PVA-immobilized denitrifying photosynthetic bacterium, Rhodobacter sphaeroides
Abstract A newly isolated denitrifying strain, Rhodobacter sphaeroides NII2 was immobilized in polyvinyl alcohol (PVA) gel, and the properties of the cells in the gel were examined. The immobilized cells had low or almost no denitrification activity, but the cells were activated by incubation in light with culture medium for denitrification containing 0.5% nitrate and no other nitrogen source. Cells grown in the dark were activated by incubation at an earlier stage and to a higher rate than the light-grown cells. The activation was markedly enhanced in the PVA gel with a low cell concentration. The immobilized cells consumed nitrate with a temporary accumulation of NO 2 and evolved nitrogen gas. The immobilized cells could use various organic compounds as electron donors for denitrification. Thus, the immobilized cells were applied to a continuous treatment of synthetic wastewater using an aparatus devised by this laboratory. The results showed an efficient removal of NO 3 -N from the test water.
