The move from print to online journal publishing has allowed the proliferation of journal access programs aimed at poor countries. These programs offer access to online journals on very favorable terms to developing country institutions and readers and are based on the premise that developing world scientists can contribute significantly to ameliorating the conditions of life in their countries. The authors give a brief overview of the environment in which these programs emerged, discuss different orientations of the major programs, examine the case of the Health InterNetwork Access to Research Initiative (HINARI), consider why the World Health Organization (WHO) runs a journal access program for developing countries, and conclude with the accomplishments of HINARI.  相似文献

This paper tackles the practical application of statistical tools. Chemical development is a rich area for collaboration between statisticians and chemists, but most statisticians encounter difficulties in promoting the tools to this client group. This paper, presented from a chemist's perspective, is intended to help bridge the gap between the two professions. The paper explores differences in uptake and attitudes towards adopting these techniques and suggests what has hindered or helped the process of effective application of experimental design.

After severe head injuries, children can display behavioural problems for many years. Factors related to the individual have been discussed in other articles, and authors have also suggested that resulting behaviour problems may affect the family. This paper assesses the direct effect of the injury and events around it on the family. The reaction of the family may contribute to the persistence of the behavioural change, rather than just be a result of it. This paper describes the effect of the accident on family relationships and discusses the behaviour of the identified victim in terms of the stage of the family life cycle. The family as a whole, and not just the child, is a victim of the event, and therefore the use of family therapy is an important and appropriate part of treatment. A comparison of family and individual therapy is made, and the problem of assessing whether behavioural changes are related to organic brain injury is addressed.  相似文献

To evaluate the completeness of registration of infant and child deaths in Egypt, reinterviews were conducted with families who had reported a death of a child under age 5 in the five years before the survey for two national surveys recently conducted in Egypt: the United Nations PAPCHILD survey of1990-1991 and the Egyptian Demographic and Health Survey (EDHS) of 1992. The survey instrument included questions regarding notification of the death at the local health bureau. If the family said the death had been notified, separate employees searched the health bureau records for the registration. Overall 57% of infant deaths were reported as notified and 68% of those death reports were found; the corresponding figuresfor child deaths were 89% and 74%. Using the percentage reported as notified as an estimate for completeness of registration, we adjusted upward the national infant and child mortality rates from registration data, giving values of 73 per 1,000 for infant mortality and 99 for 5q0 for the period 1987-1990. These values are approximately 20% above the corresponding direct estimates from the PAPCHILD and EDHS surveys.  相似文献

This article provides an implementation fidelity evaluation of the fourth experimental trial of Project Towards No Drug Abuse (TND). Two theoretical content components of the curriculum were examined to increase our understanding of the active ingredients of successful drug abuse prevention programs. A total of 18 senior high schools were randomly assigned by block to receive one of three conditions: cognitive perception information curriculum, cognitive perception information + behavioral skills curriculum, or standard care (control). These curricula were delivered to both regular and continuation high schools students (n=2331) by trained project health educators and regular classroom teachers. Across all program schools, the two different curricula were implemented as intended, were received favorably by students, and showed significant improvements in knowledge specific to the theoretical content being delivered. This pattern of results suggests that the experimental manipulations worked as intended, and thus, permit the attribution of future behavioral outcome differences between conditions to differences in content of Project TND material provided rather than to differences in the fidelity of delivery. Further, our findings indicate that Project TND can be implemented effectively with low and high risk youth in a general environment as well as with high risk youth in a more specialized environment.  相似文献
