Climate control through ionization

This paper summarizes some of the experimental evidence of the apparent biological effects produced by atmospheric ionization. Thermionic ion sources are discussed and the results of experimental determinations of their characteristics are presented.     

Linguistic influences on professional communication and recognition: A study of chemists and engineers in two Quebec universities

Linguistic influences on networks of professional communication and recognition among engineers at two Quebec universities were examined. It was hypothesized that chemists and engineers affiliated with the French medium University of Montreal and the Ecole Polytechnique would be less active in research and more likely to obtain scientific recognition locally and to feel professionally unrecognized outside Quebec compared to their colleagues at McGill University. The findings suggest that the localizing effects of using a medium of scientific training which is not the predominant language of international scientific communication and recognition (French) are ambiguous. Although chemists and engineers at the French medium institutions were less active researchers, their language of professional communication with other scientific communities was English and there was little sense of isolation.This research has been supported by grants from the Canadian Council and the Ecole Polytechnique of Montreal. The authors also wish to thank Miss Madeleine Palmer, Miss Daniella Quiniou and Miss Rosalba Casas for their help in data collection for this paper.     

Was macht den Sport zum Mediensport?

The popularity of sports varies to different extents around the world and leads to the question: what is a media sport? This contribution discusses definitional principles with the goal of using a model to establish the basis of categorization for future empirical analysis of diverse sports types. Media sports are defined as characteristic of movement structures in the culturally differentiated media sports complex. Features of media sports are distinguished according to the dimensions of context, organization, and (interactive) structure. It becomes clear that media sports types are not only characterized by cultural grounding, success, and charismatic stars, but can also exhibit structural distinctions. In conclusion, real, media-driven, and medial media sports are differentiated to demonstrate application of the model.

Science Learning in Special Education: The Case for Constructed Versus Instructed Learning

Throughout the history of education, debate has existed between the relative merits of instructed versus constructed knowledge. In this article, we review our program of research in science education for students with disabilities in order to reveal some insights into this debate. We review research in science curriculum, mnemonic strategies, text-processing strategies, hands-on approaches, coached elaborations, “discovery” learning, correlates of effective inclusive science classrooms, and class-wide peer tutoring with differentiated curriculum enhancements. Overall, both instructed and constructed knowledge are important and can be facilitated with appropriate instructional strategies. Implications for practice and future research are provided.
