The innovative teaching, knowledge and technology production and societal service activities of academics are largely discussed within the entrepreneurial university discourse in Higher Education journals. Therefore, this research focuses on a meta‐synthesis of Higher Education articles to better understand the concepts of the entrepreneurial university and entrepreneurial academic. After the systematic elimination based on keywords and titles, 25 articles have been selected from the top 10 Higher Education journals in the SCImago Journal Rankings. Content analysis was performed on these articles to highlight the common operational areas in entrepreneurial universities and activities of entrepreneurial academics. The meta‐synthesis shows that, both for universities and academics, entrepreneurship is overwhelmingly characterised by the commercialisation of scholarly activities that enrich institutional income revenue as well as academics’ personal income. However, such an approach can distance universities from their mission of public good; so Higher Education administrators should create mechanisms that would allow both to take place in a balanced way.  相似文献

ABSTRACT

With increasing demand for improved medical equipment and healthcare, next-generation biomedical engineers need strong design skills. Equipping biomedical engineering students with tools for idea generation and development can increase student design success. Design Heuristics are an ideation tool developed through empirical studies of product designs. While identified in the mechanical engineering space, Design Heuristics may be applicable in biomedical engineering design. In our study, we implemented a Design Heuristics session during upper-level undergraduate and first-year graduate biomedical engineering design courses. We examined the applicability of Design Heuristics within individual and team concept generation contexts. The findings demonstrated that biomedical engineering students were able to use Design Heuristics to generate multiple concepts, and that initial concepts produced using Design Heuristics were carried over into final team design. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design.  相似文献

In this article, the work of three international governmental organisations (IGOs) dealing with human rights will be discussed, namely the United Nations Educational, Scientific and Cultural Organization (UNESCO), the United Nations Children's Fund (UNICEF)1 and the Council of Europe (CoE). In the first section, the main characteristics of the three IGOs in terms of similarities and differences will be elaborated. Then, their human rights approach to education will be described, dealing with the legal foundations. In the final section, the different strategies of implementation based on both their official mission statements and their present strategy papers will be evaluated under the heading ‘competition vs. cooperation’.  相似文献
