Arguably the most striking recent departure in online publishing has been the succession of initiatives designed to provide free or reduced-rate journal access to the developing world. This article examines the motives behind some of these campaigns and probes the difficulties associated with supplying scientific information equitably, productively, and to an appropriate readership in developing or transitional countries. It considers the strengths and weaknesses of the main solutions currently on offer, while advocating a more unified approach based on the three C's of co-ordination, comprehensiveness, and clarity. 相似文献

Twenty-four children with specific reading disability, originally studied and treated at the Bellevue Hospital Mental Hygiene Clinic between 1949 and 1951, were reexamined as young adults between 1961 and 1962 with the battery of tests given to them ten to 12 years before. Their specific perceptual problems and evidence of lack of clear- out cerebral dominance persists, although in less severe form. Those patients who as children had neurological signs in addition to the specific reading disability showed less improvement than those who had none. 相似文献

We examined whether sexual attitudes of adolescents were related to their self-reported sexual risk behavior by analyzing survey data from 1,052 boys and girls aged 14 to 17 years from a low income, urban community. Sexual behavior norms that may increase sexually transmitted infection/HIV risks in youth were sanctioned more by males and by sexually experienced youth, but their attitudes were unassociated with either their age or race/ethnicity. Endorsement was correlated with greater intention to have sexual intercourse among all youth. Among sexually experienced participants, it was associated with earlier sexual debut, more partners, and less intention to use condoms but not with the number of unprotected sexual episodes in the prior six months. Sexual attitudes of youth may conflict with initiation and maintenance of safer sex practices, making them vulnerable to HIV and other sexually transmitted infections. Risk reduction interventions for adolescents should address this. 相似文献
