The emphasis on competitiveness and the knowledge-based economy in European policymaking has resulted in a heightened focus on monitoring and steering the science system, particularly through metric-based instruments. Policymakers’ general aims of fostering excellent research and breakthroughs are shared by researchers as well; however, below the surface is a paradox that is rarely discussed. The political system and the science system understand and pursue these concepts and objectives differently. Through two case studies on high-performing university-based research environments in Denmark and Sweden, this article uncovers the ways in which highly successful researchers often behave in ways that run counter to policy steering attempts. They do this by shielding themselves and their research group from steering pressures originating in the political system. Using Luhmann’s systems theory, the cases demonstrate why the relationship between the science system and the political system needs to be understood as a horizontal rather than a vertical relationship, and using concepts from organizational theory, provides a model and terminology for identifying and analyzing the types of mechanisms and strategic responses that the science system uses to shield itself from political steering pressures.  相似文献

Gifted girls of color represent a potentially untapped resource for increasing and sustaining a diverse science, technology, engineering, and mathematics (STEM) workforce. Girls of color possess unique mathematics and science gifts and talents that can remain unrealized if not addressed before middle school. Culturally responsive STEM out-of-school-time (OST) activities can be an effective means to develop STEM capacity in gifted girls of color. The researchers present three considerations to support the implementation of STEM OST. First, they offer a rationale for culturally relevant STEM enrichment activities for gifted girls of color. Next, the researchers consider how culturally relevant STEM OST activities can help to close the achievement gap. Finally, they explain how professional mentorship opportunities within OST activities can help gifted girls of color navigate the STEM pipeline.  相似文献

A particular subtype of learning disability (nonverbal learning disability) is described. This subtype of individuals with learning disability is seen to be at particular risk for depression and suicide. The origins of the study of this subtype of learning disability, its incidence in various forms of neurological disease, disorder, and dysfunction, and its behavioral and socioemotional manifestations (including its association with significant internalized forms of psychopathology) are described. A case history of a young woman who manifests this disability and who has attempted suicide on three occasions is also presented.  相似文献

With the high prevalence of college students experiencing psychological distress, it is becoming increasingly important to provide prevention and early intervention programs in addition to traditional psychological counseling services. This study examined the effectiveness of a suicide prevention program led by peer educators/trainers on a diverse college campus. Twenty-five suicide prevention workshops were conducted with 479 attendees. Preworkshop and postworkshop assessments revealed significant improvements in participants’ knowledge of suicide and resources. Recommendations for campus-wide suicide prevention efforts using diverse peer educators that reflect the students’ demographic and cultural background, recruitment strategies, and utilization of outreach programming in suicide prevention.  相似文献

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers’ knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K–12 teachers at a national science teachers’ conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices.  相似文献
