The main purpose of the paper is to find out the provision of providing Networked Services (NSs) among National Institute of Technology (NIT) libraries in India. Methodology used for collecting data was questionnaire. The survey findings indicate that the majority of libraries prefer to provide communication network services (telephone, Internet, e-mail, facsimile etc), online journals (90%), automated catalog system (85%), multimedia databases (85%) and support (70%) services rather than the other services. Concerning the zone wise performance, south zone (80%) libraries are more potential than the other zone libraries in providing NSs. 相似文献

This paper draws on findings from a research project funded by the Scottish Executive which analysed the gender balance in teaching and explored the underlying reasons for the decline in the number and proportion of men, particularly in secondary schools. As in other developed countries, such as Australia, the USA and Canada, the proportion of men entering teaching has declined fairly rapidly over a ten‐year period. At a time when women are participating in paid work in greater numbers than ever before, their concentration in certain areas of work, particularly in the service sector and the ‘caring’ professions, is increasingly apparent. Despite the clarity of this trend, it is evident that responses from academics and policy‐makers have been very different, with some policy‐makers linking the declining proportion of men in teaching with the problem of boys’ underachievement and a perceived ‘crisis in masculinity’, whilst some feminist writers have questioned these views, drawing on recent gender theory which questions the utility of the binary categories of ‘man’ and ‘woman’, instead suggesting that gender is performed and may have little to do with the body of the person who is involved in the particular performance. Sex and gender thus become decoupled, with the focus on individual actors freely choosing the version of gender they wish to practice. This line of argument suggests that the sex of the teacher is irrelevant; what really matters is the way in which they perform gender in the classroom. Work on the gender balance in teaching therefore provides an opportunity to reflect on underlying tensions in gender theorising and policy‐making. The paper begins by considering tensions between modernist and post‐structuralist accounts of sex and gender. Having outlined the underlying theoretical tensions, it then goes on to consider the accounts given by teachers and students of the reasons for their own choice of teaching as a career, their experiences in teaching and their views of the reasons underlying the declining proportion of men in teaching. The aim is to consider whether students and teachers believe that sex is an important variable structuring their lives, including their decision to become a teacher and their experiences of working as a teacher, or whether they regard gender as something which is chosen from a wide repertoire of options and is relatively free from the constraints of embodiment. In relation to research on the gender balance in teaching, the paper concludes by suggesting that there is a need to make use of the idea of gender as performance, whilst at the same time holding on to the foundational concepts of ‘woman’ and ‘man’. This is necessary to monitor and understand the career paths and underlying power relations of women and men in teaching and to transform these over time. 相似文献

Previous research has established that interest in a text is related to better comprehension and recall, but the impact of interest on comprehension in testing situations has not been widely investigated. This study used Hierarchical Linear Models (HLM) to examine the relationship between students' interest in reading passages and their performance on reading comprehension test items over those passages. The study involved 19,735 students in Grades 4 through 8. Stimuli consisted of 98 different reading passages. A small but significant relationship between interest and test performance was found, which was stronger for girls and for students of higher ability levels. A second HLM analysis was employed to explore whether certain passage characteristics were associated with higher or lower interest. The implications for test construction are discussed. 相似文献

Dimensional analysis is a useful tool which finds important applications in physics and engineering. It is most effective when there exist a maximal number of dimensionless quantities constructed out of the relevant physical variables. Though a complete theory of dimensional analysis was developed way back in 1914 in a seminal paper by Buckingham, systematic procedures necessary to construct a sufficient number of dimensionless quantities have become available only recently. In this article, we describe with an example the steps involved in the Szirtes algorithm which is fairly simple to understand and quite straightforward to use. 相似文献
