In 2004 the Dutch Ministry of Education, Culture and Science set a concrete target: by 2010, close to 50% of the age cohort should participate in higher education, following the targets set in the UK and Sweden. However clear the target is set, the ways to achieve it are far less specified. In the article a number of possible instruments to achieve the target are discussed and their relevance in the Dutch context is analysed. It is concluded that there are a limited number of policy instruments available. However, given the devolution of access policy to the higher education institutions and the influence of broader societal trends on participation our expectations on what government can do to reach its target need to be modest. 相似文献

The many challenges faced by health sciences libraries of all types and sizes often require innovative solutions. When an innovative solution involves calculated risk taking, the approach is called intrapreneurial. At the University of Miami School of Medicine, an intrapreneurial approach solved the fiscal problems of the biomedical communications unit. The Louis Calder Memorial Library inherited these problems when the Department of the Library and Biomedical Communications was created in the early 1980s. In this paper, two intrapreneurial programs are described, and the benefit and suitability of this management style to information services are demonstrated. 相似文献

This study describes response to intervention (RTI) screening and progress‐monitoring instruments and procedures in 41 local school settings. For screening the schools most often used published reading assessments or commercial products; a three‐times‐per‐year screening schedule was most prevalent. For progress monitoring schools most often relied on published reading assessments; a weekly progress monitoring schedule was most prevalent. The variability between local school practices is discussed with regard to efficiency, equity, and viability of RTI. 相似文献
