The Family Service Units is a national charity working in some of the most deprived areas of the country. This paper is concerned with one part of its work, The Connections Project. This project aims to develop non-punitive anti-bullying partnerships between young people, schools, adults in the community and other agencies. This article focuses on a particular aspect of this project, the Support Code, which seeks to promote an ethos of proactive mutual support. The development is described and the teachers' reactions are explored. Though this work is currently being undertaken in primary schools, much is applicable to the early years of secondary education too.  相似文献

This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients.  相似文献

Too often there is far too large a gap between the sort of literature recommended by the English teacher and the normal reading tastes both of children and adults (W. Stewart, 1950).  相似文献

The “learning disability” label is a relatively new addition to the field of special education and its effects have begun to be investigated. This study examined the differences produced by two categorical labels on students impressions of the “disturbingness” of behavior and their willingness to work with the labeled child. Aggressive behaviors thought to be exhibited by learning disabled youngsters were rated differently from identical behaviors thought to be exhibited by emotionally disturbed children. Implications of this study suggest that the “LD” label may connote a milder form of disability; and that teacher and professional training institutions should consider the deleterious effects labels may convey with regard to expected behaviors.  相似文献

This paper explores the association between moderate levels of physical activity (PA) and health benefits in well being and symptoms such as tiredness, back pain, and constipation. Participants in the Australian Longitudinal Study on Women's Health, 14,502 young women (ages 18-23 years), 13,609 middle-age women (45-50 years), and 11,421 older women (ages 70-75 years), answered questions about vigorous and less vigorous exercise (used to determine a physical activity score), well being (SF-36), symptoms, and medical conditions. There were significant associations between the PA score and SF-36 in each cohort. Odds ratios (OR) for a range of symptoms and conditions were lower for women who reported low to moderate activity than for sedentary women, for example, for young women or for constipation = 0.76 (CI, 0.65-0.89), for middle-age women or for tiredness = 0.70 (0.63-0.78). There was no threshold of PA at which health benefits increased significantly. Although cross-sectional, the findings suggest that low-to-moderate levels of exercise are associated with a range of health benefits for women of all ages. These preliminary findings will be followed up during the longitudinal study.  相似文献
