The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions.  相似文献

Issues associated with school absenteeism have attracted considerable attention and have long been one of the focal points of government strategies for school improvement. Pupil non-attendance is not a new phenomenon and featured prominently in Her Majesty’s Inspectors’ reports from 1839. This paper outlines the patterns of and influences on elementary education in early Victorian industrial Monmouthshire during the period 1839–1865. The twin problems of irregular attendance and early withdrawal of pupils are discussed together with the limitations and unreliability of contemporary statistics. An examination of the reasons for absence is then discussed together with the remedies proposed to alleviate the problem with particular reference to the contribution of the Prize Schemes. The paper illustrates the disadvantages of basing an educational system on voluntary endeavour and enlightened self-interest and highlights the paradox that, despite the introduction of mandatory attendance, the problem is still persistent and protracted and finding definitive solutions still remains elusive.  相似文献

The purpose of this paper is to examine whether the technical universities have been more successful in facilitating the spillover and commercialization of knowledge. We compare the impact of technical and general universities on the performance of knowledge-based firms. Based on a unique data set consisting of publicly held high technology firms, the empirical evidence suggests that, in fact, firm performance is not influenced by the type of university. Technical universities do not have a differential impact on firm performance from more general universities.  相似文献

This study explores working students' college experiences using the grounded theory approach. Focus groups were conducted to allow working students to elaborate on their college experiences, clarifying issues not easily addressed through surveys. Two theoretical propositions are offered to describe how working students are constantly searching for meaningful work as well as meaning in their work. It is important for institutions to consider work as an educationally purposeful activity outside classroom and to create job opportunities that benefit students academically, socially and financially.  相似文献
