We compared Index Medicus and Drug Literature Index during a search concerning the toxicity of eight drugs used in treating tropical diseases. Indexes covering the years 1969, 1970, and 1971 were searched. Index Medicus produced 198 citations and Drug Literature Index 309. There were seventy citations that appeared in both indexes, a duplication of 16%. Highest percentage of duplication for any one drug was 38.9%. We concluded that Index Medicus and Drug Literature Index provide complementary coverage in the area of drug toxicity and that, therefore, both tools should be consulted in searches of this nature.  相似文献

Although there is increasing interest in promoting mental health and wellbeing within education, to date, the voices of young people appear to have been almost completely overlooked in the development of school-based mental health practices. This is despite increasing focus on young people’s participation; and the fact that young people may be best positioned to understand the pressures of contemporary society. This paper, co-authored by educational psychologists (EPs), school students and the school vice-principal, documents the development of a student-led mental health initiative within a high-achieving girls’ grammar school, led by students aged 12–18. Following EP input, the students devised a whole-school, student-friendly mental health strategy with the support of the EPs and senior school staff. As the project progressed, it became evident that applying even carefully selected adult mental health models to school contexts might not be appropriate; instead the students advocated for young person-friendly, innovative, contemporary and creative ways of communicating information about mental health, which avoided stigma. The students involved were well-placed to identify environmental stressors and to disseminate their strategy. The authors conclude that mental health planning in schools should encourage greater student participation, show caution over applying adult mental health models and promote greater use of technology or visual resources.  相似文献

Twenty five class teachers completed a "Strengths and Difficulties" assessment for 523 children aged from 7 to 11 years of age. Children self-completed a 39-item "My Life in School" questionnaire. One third of the sample were self-reported victims of bullying behaviour. Boys with poor prosocial skills, emotional problems and general difficulties with social interaction, expression of emotion and hyperactivity were at greatest risk of being bullied. There was no significant effect of age. The data support previous research findings that gender influences the prevalence of bullying but not that younger children are more vulnerable. This study provides new evidence that teachers recognise social behaviour and interactions that can significantly affect whether primary school children are bullied.  相似文献

The causes of the transfer of technology between countries is now seen as an important dimension of the diffusion of new products and processes. Despite its obvious importance, there has been little empirical research investigating the international transfer of technology, although the work of Schiffel and Kitti (Research Policy 7 (1978)) provides a useful foundation on which to build. The research reported below tests the hypothesis that the transfer of technology between countries, as measured by the movement of patented invention, is influenced by both supply side and demand side factors. The principal variables are: patenting activity in the country of origin; the size of the recepient economy; international trade in goods and services; and the operations of multinational producing enterprises. These vaiables explain most of the variation across countries in the transfer of U.S. technology abroad. The worldwide distribution of U.S. based multinational enterprises appear to play an important part in explaining U.S. technology tranfer. On the other hand, the remaining international differences in patent law do not seem to significantly affect patent flows between countries.  相似文献

There has been considerable investment in the use of interactive whiteboard technology in schools in the UK. There is evidence that whilst teachers understand such technology, many do not understand the nature and implications of interactive learning. Observation and analysis of 50 video‐recorded lessons taught by ‘successful’ teachers drawn from mathematics and modern foreign language departments in secondary schools led to the classification of three types of practice representing a spectrum of increasing interactivity. The nature of this good practice was analysed together with criteria for assessing the changes being wrought by technology in approaches to learning and teaching. The investigation concluded that the use of new technology alone cannot lead to enhanced learning. Teachers also need training to develop awareness of the relationship between approaches to interactive learning and conceptual and cognitive development in subject areas.  相似文献
