We investigate how outside directors on supervisory boards influence innovative activities of the firms they advise and monitor. Based on panel data on the largest German companies, the econometric analysis shows a positive influence of external executives on innovative firm performance, measured by patent applications. Differentiating between outside directors from innovative and non-innovative companies reveals that only outside directors from innovative firms increase patenting activities at the firms they advise and monitor. This effect increases with the technological proximity between the appointing firm and the outsider's home firm. Outside directors from non-innovative firms are negatively associated with the appointing firm's innovativeness. The results indicate that external executives with an appropriate professional background can provide valuable specific knowledge and expertise to the board. 相似文献

The twin challenges of inactivity and the 2012 Olympics have tightened the focus in UK sport promotion. However, the twin track approach which treats these challenges as distinct concerns may limit the efficacy of interventions in either area. We propose that a continuum between participation, performance sport and elite achievement represents the most efficacious and logical focus for practitioners and researchers alike. We explore the genesis of this, and other problematic features through critical consideration of key theories. Finally, we propose a multidimensional approach to lifelong sport and activity participation as a theoretically justified basis for research and intervention design. 相似文献

This is a case study of a physics undergraduate who claimed that he “uses physics to understand other subjects.” This statement suggested that this student could describe issues concerning the transfer of learning and especially instances of far transfer. Detailed instances of far transfer have been difficult to replicate in lab settings. Therefore, three interviews were designed to investigate this student’s claims about using physics to understand other subjects as a means to better understand far transfer processes. Transfer in this case study is defined as the personal construction of relations of similarity. Furthermore, I operationalize this definition of transfer via 12 aspects of transfer derived from the work of several contemporary researchers who study the transfer of learning. As part of this case study I also investigate the subject’s motivation for engaging in far transfer. Directions for future research are discussed which includes the need to study the role of personal epistemology in far transfer as well as a larger investigation of students who transfer broadly across school subjects. 相似文献

This study describes the process of developing and validating an instrument that measures students’ innovation capacities as a higher education outcome. We introduce an interdisciplinary theoretical framework used to generate items and cover extant literature drawn primarily from the fields of higher education and entrepreneurship studies. We further discuss our use of latent trait theory and item response models to guide instrument development and measure scoring. We then provide the results of a second-order confirmatory factor modeling procedure, which indicated robust model fit. We close by discussing findings and offering implications for both higher education scholars and institutional researchers. 相似文献

Fifteen-day-old rats made random choices in a T-maze, while adult levels of alternation (approximately 70%) were noted among 30-day-olds. Also, younger pups were insensitive to a lengthening of the intertrial interval, unlike older animals whose rate of alternation decreased when a 1-h delay was interposed between arm entries. These findings are consistent with the hypothesis that hippocampal development is a factor in the ontogeny of postweaning locomotion. The unsystematic pattern of goal-arm selections among 15-day-olds suggests that ontongenetic variation in the utilization of stimuli may underlie developmental shifts in spontaneous alternation. 相似文献

This study investigated the effect of an auditory training programme with backward readers who were also deficient in one or more auditory perceptual subskills. Thirty subjects were randomly assigned to one of three groups. The experimental group received a nine hour taped programme devised by the experimenter and designed to teach the skills of auditory discrimination, memory, analysis and synthesis and auditory-visual integration. The comparison group listened to stories on tape for the same duration as the experimental group, while the third group served as a control merely being tested at the beginning and at the end of the experiment. It was found that although the training programme significantly improved the performance of the experimental group over the other two groups on a total auditory perceptual test, there was no corresponding improvement in reading, on word recognition or comprehension tests. The particular auditory subskills which appeared amenable to training were auditory discrimination (rhyme) and auditory synthesis (blending and closure). 相似文献

Children raised in neighborhoods with low socioeconomic status (SES) are at risk for low academic achievement. Identifying factors that help children from disadvantaged neighborhoods thrive is critical for reducing inequalities. We investigated whether children’s prosocial behavior buffers concurrent and subsequent academic risk in disadvantaged neighborhoods in Bradford, UK. Diverse children (N = 1,175) were followed until age seven, with measurements taken at four times. We used governmental indices of neighborhood-level SES, teacher observations of prosocial behaviors, and direct assessments of academic achievement. Neighborhood SES was positively associated with academic achievement among children with low levels of prosocial behavior, but not among children with high levels of prosocial behavior. Prosocial behavior may mitigate academic risk across early childhood. 相似文献

Millions of college students in the U.S. are enrolled in online courses, with the global pandemic resulting in a “pivot to online” for educational and health reasons. African-American college students continue to face barriers to academic success, and this response to Kuo and Belland (in Educ Technol Res Dev 64(4):661–680, 2016) investigates how the concept of “learner interaction” supports success. Finally, this response includes examples from online courses informed by “critical humanizing pedagogy,” in which social interaction is a key driver of learning.

Interactive computerized modules have been linked to improved retention of material in clinical medicine. This study examined the effects of a new series of interactive learning modules for preclinical medical education, specifically in the areas of quiz performance, perceived difficulty of concepts, study time, and perceived stress level. We randomly allocated 102 medical student volunteers into control and experimental groups. All participants studied selected anatomical and physiologic concepts using existing material (lecture notes, textbooks, etc.), while those in the experimental groups used the new interactive modules as well. All participants completed a quiz to test their knowledge of the assigned concepts and a survey to assess their subjective experiences in studying with the modules. We found a trend toward higher quiz scores in the experimental group relative to the control group, though it did not reach statistical significance (P = 0.31). Perceived concept difficulty was significantly reduced among those who studied with the modules (P < 0.001), and the number of hours spent studying the concepts was significantly increased (P = 0.028). Of those who used the modules, 83% rated them as “very helpful” or “extremely helpful.” No significant differences existed between participants' reported stress levels during the course of the study (P = 0.44). Our data suggest that medical students may learn more effectively and feel less intimidated by difficult concepts when interactive modules supplement traditional instruction.
