چکیده
1. My main goal was to develop statistical approaches to the study of community dynamics in the presence of large numbers of species. In previous work, I used semi-parametric methods to build up a picture of community dynamics aggregated into a small number of categories. The basic idea was to predict the composition of a community one time unit into the future, given its current composition, using information on the future compositions of communities with similar current composition. We applied this idea to data on changes in coral reef composition from a large number of reefs, where composition was grouped into three broad categories. The semi-parametric approach allowed us to avoid assuming a particular form for the relationship between current and future composition. We used numerical integration to study the long-term behaviour of the model.

Professional development of faculty members as a part of human resources development at universities is of special importance. One of the common strategies for the professional development of these members is sabbatical leave. The present study was carried out with narrative-based research methodology as well as interpretive approach to assess the experiences of faculty members from sabbatical ...

متن کامل1 A Research Proposal Submitted to NSFC
In Spring 2013 I was on sabbatical with University of Electronic Science and Technology of China (UESTC). My original proposal was to conduct a research project with a professor in UESTC and to submit a couple of conference papers and a journal paper. My actual achievements were more productive. This report summarizes the research activities I was involved.
