An agenda for future higher education research is proposed which incorporates four interconnected elements: changing social contexts; their implications for higher education; mechanisms of interaction between higher education and society; higher education’s impact on society. The role of comparative research in investigating these topics is discussed and a set of priorities for future research questions is proposed. This final article draws heavily on the HELF final report published by the European Science Foundation entitled Higher Education Looking Forward: an agenda for future research and written by the author together with Jurgen Enders, Christine Musselin, Ulrich Teichler and Jussi Valimaa. The author acknowledges the contributions of his co-authors of the HELF report to the ideas and words contained in the present article.  相似文献

In the United States, the decision to commit extensive public resources to sport facilities is a contentious topic of debate. Elected officials often commit substantial public resources to sport facility projects amidst contrary empirical evidence and mixed residential approval. This behavior not only implicates the presence of political activity to advance a course of action, but also suggests an escalation of commitment (EoC), the subject of this study. The authors implemented a collective case study approach to examine three municipalities with long-standing histories of subsidizing professional sport facilities. Data collected from influential elected officials and public leaders (N = 13) as well as documents and records revealed (a) political action to be essential in EoC with decisions involving multiple stakeholder groups; (b) the influence and interaction of political action within each EoC determinant; (c) the substantial role of support, resources, power, and influence in efforts to increase and prevent commitment to a failing course of action; and (d) noticeable spillover effects from use of political activity in EoC.  相似文献
