Stephen Court 《Higher Education Quarterly》1996,50(4):237-260
This paper reviews surveys of the use of time by academic staff between 1962 and 1994. It reports on the findings of a time diary survey in 1994 of the use of time by academic and academic-related staff at British'old'universities during working weeks in term-time and vacation. The results of the time diary survey are analysed according to respondents'sex, staff grade, type of week, age, type of work, and time when work took place. The results are compared with results of previous surveys, and trends through time are suggested. In conclusion, the paper considers the recent mass expansion of higher education, the effects of this in increasing the workload of university staff, and measures to ameliorate this situation. 相似文献

Stephen T. Kerr 《Publishing Research Quarterly》1992,8(4):33-43
In order to determine the potential of alternative technologies in social studies education, we must understand the goals
of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author
suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life
and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack
of time and money for teachers to experiment with the technologies.
Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses
on the application of new technologies in schools and other educational environments, and particularly on the ways in which
technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions.
He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational
system of the former USSR. 相似文献

Empirical research provides evidence that electronic communication does not change government agencies into post-bureaucratic organizations. Structuration Theory is used to explore the interaction between e-mail use, communication patterns of civil servants, and two bureaucratic characteristics: formalization and hierarchy. Previous research suggested that the use of e-mail leads to less formalization and less hierarchy, but empirical research in three bureaucratic organizations in the Netherlands leads to different conclusions. First, the use of e-mail leads to informal formalization: the style of communication is more informal but the content focuses less on personal issues and emphasizes efficient recordings of agreements. Second, the use of e-mail leads to hierarchical horizontalization: horizontal contacts take a more central position in bureaucratic organizations but these horizontal contacts are tightly linked to vertical structures. The result of the interaction between e-mail and government bureaucracy is horizontal communication directly linked to vertical structures. Electronic communication turns government agencies into late-bureaucratic organizations. 相似文献

The current societal and professional context presents a variety of ethical challenges to decision makers. The importance of educational preparation for ethical decision-making and ethical leadership has been addressed in the literature of library and information science (LIS), among other professions. However, it can be quite difficult to measure the impact of professional ethics education on students. This article is based on an evaluation of published original research related to ethics education in disciplines supported by professional education, including education, nursing, allied health, journalism, social work, public health, engineering, and LIS. The study considers data related to research design, methodologies used, populations studied, approaches to measuring impact, levels of impact, and publication in the journal literature. Results indicate more extensive research in education and nursing as compared with other fields, a lack of baseline data gathering for comparison, a reliance on a limited number of data-gathering techniques, and a tendency toward studying alumni over current students 相似文献
