The university of the future: Boyer revisited 总被引:2,自引:0,他引:2
Rita Johnston 《Higher Education》1998,36(3):253-272
The paper considers Boyer's declaration that the work of a university centres around four areas of scholarship: discovery, teaching, application and integration. The evolution of the modern university is analysed in terms of the struggle for dominance by each area of scholarship in turn, to meet the needs of the contemporary society. It identifies three major times of upheaval. At the birth of the Civic universities, the scholarship of discovery was added to that of teaching. With the plate glass expansion and the institution of the polytechnic sector, the need for application was acknowledged. As knowledge has expanded and new subject areas continue to form where disciplines connect and overlap, the discipline of integration has become increasingly relevant and, with the merging of the polytechnic and university systems, it could be argued that there has also emerged a need for a management system to support that integration.The paper concludes that Boyer's four areas of scholarship are still necessary, and remain core to the business of universities, but they are no longer sufficient for survival and development unless the scholarships are considered, not only at an institutional and national level, but also as part of a global learning system. The four scholarships will only be guaranteed if the unique role of the university itself is defined and defended. 相似文献

This article aimed to identify the effect of university-industry (U-I) collaborations on the innovative performance of firms operating in the advanced materials field, and by doing so, it proposed an original classification of the research organization partners. The main contribution resides in the estimation of the role played by collaborations with differently experienced scientists. In contrast with previous studies, whose empirical setting was the life science industry, in the advanced materials industry the most effective collaborations are not with “Star scientists”, but with “Pasteur scientists”. The latter concept was empirically tested first by the authors of this article, to deepen the present understanding of industrial heterogeneity in innovation processes and to offer new insights for the formulation of corporate innovation strategies. The results of the estimation of a negative binomial regression model applied to a sample of 455 firms active in the photocatalysis in Japan confirm the idea that engaging in research collaborations, measured as co-invention, with “Pasteur scientists” increases firms’ R&D productivity, measured as number of registered patents. In contrast, we found that firms’ collaborations with “Star scientists” exert little impact on their innovative output. 相似文献

This study explores differences in exercise and walking behavior among subjects who reported temporary or long-term illnesses or injuries serious enough to have limited physical activities. The study is primarily concerned with specifying similarities and differences in correlates of vigorous exercise and walking among illness/injury groups in comparison to a healthy sample. Subjects in the analysis (N = 2,053) were drawn from a multiwave mailed survey of a probability sampling of the adult population residing in households in San Diego, California. Although differences were found in correlates of walking and vigorous exercise among the groups, self-efficacy, the belief that one is able to perform specific activities, was the most powerful and statistically significant correlate of both walking and vigorous exercise among all groups. 相似文献

Ernesto Caffo Gian Paolo Guaraldi Giorgio Magnani Rita Tassi 《Child abuse & neglect》1982,6(4):453-463
At the obstetrical clinic of Modena University and a family center of the same municipality during the first six months of 1980 a questionnaire based on "Risks of Child Abuse" by Kempe, Gray and others was administered to 33 expectant mothers during the third trimester of pregnancy, a few days after delivery, and a month and one-half after childbirth, for the purpose of examining the mother-child relationship. Two principal groups of "risk factors" which may lead to child abuse and neglect appeared: mothers with preceding personal and social experiences, and cases of medical intervention (e.g., prematurity, caesarean). Use of a questionnaire that permitted early diagnosis made possible help in establishing a good mother-child relationship in the first months of life. Such help can be given by the hospital and public centers both before and after birth. 相似文献

This experiment tested the hypothesis that prose materials related to existing knowledge structure will be less subject to retroactive interference (RI) than will materials not as easily related to existing knowledge structure. Subjects read successive passages labeled with the names of famous or fictitious characters. In comparison to control groups, subjects receiving initial passages labeled with fictitious names experienced significant RI, whereas subjects receiving famous name initial passages did not. 相似文献

The cerebral sphingolipidoses which form part of a larger group of lysosomal disorders can be detected and conclusively confirmed
by the demonstration of the relevent enzyme deficiency in easily available tissue samples like serum. We have assayed acid
β-galactosidase, β-hexosaminidase and its isozymes hexosaminidase A and B, and arylsulfatase A in the serum of patients with
progressive cerebral dysfunction and detected 18 patients with enzyme defects, thereby confirming the diagnosis of a specific
type of cerebral lipidosis in these patients. The assay of serum lysosomal enzymes was of immense diagnostic use as it obviated
the need for highly invasive techniques like a brain biopsy. 相似文献
