Innovation and knowledge sharing across professional boundaries: Political interplay between boundary objects and brokers     

Chris Kimble  Corinne Grenier  Karine Goglio-Primard 《International Journal of Information Management》2010

The article examines the process of innovation and knowledge sharing from a perspective that focuses on the influence that local circumstances can have. In particular, it looks at the problems of knowledge sharing between groups of professionals. It presents a comparative analysis of two studies, one involving two groups of IT professionals; the other a network of healthcare professionals. The data was collected in two sets. The first set consisted of the results from two earlier, independent studies; the second was collected specifically for this article. We investigate the role played by boundary objects and brokers. Through an analysis of the interplay between boundary object and broker, we uncover the dynamics of the innovation process and show that the role played by the broker can be political. We identify two strategies that are used by brokers in the selection of a boundary object. The first is directed towards achieving a balance between the actors involved and the second is directed towards controlling their activities. We conclude by suggesting that other researchers should also consider the interplay between broker and boundary object when examining cross-boundary knowledge sharing.  相似文献   

Effect of antioxidants and exercise on bone metabolism

We examined the effects of antioxidant supplementation in association with progressive aerobic training on the bone metabolism of healthy elderly individuals. For 8 weeks, 13 participants (mean age 74 years) received vitamin C (500 mg) and vitamin E (100 mg) daily and participated in a supervised progressive aerobic training programme. After the 8 weeks, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D concentrations were increased significantly by 42.8% (P < 0.001) and 26.8% (P < 0.01) respectively, while parathyroid hormone concentration was decreased by 17.5% (p < 0.05). Of the bone markers, only bone alkaline phosphatase decreased, by 14.6% (P < 0.05). No variation was observed for ionized calcium, insulin-like growth factor-1 or insulin-like growth factor binding protein-3. Our findings suggest that 8 weeks of combined antioxidant supplementation and aerobic training modified vitamin D metabolism and parathyroid hormone concentration. These adaptations might counterbalance the unfavourable hormonal profile frequently observed in the elderly that predisposes them to accentuated age-related bone loss.  相似文献   

High-Active Children and Achievement Tests: A two-year follow-up     

Corinne J. Weithorn  Maxine Marcus 《Psychology in the schools》1985,22(4):449-458

A two-year follow-up of 52 elementary school children indicated that in fourth grade, as in second grade, language ability, as measured by the WISC-R Vocabulary subtest, was more strongly related to Achievement Test scores among high-actives than among nonhigh-actives. High-active children of low-to-average language ability had significantly lower achievement test scores than nonhigh-actives, with significant decrement in scores in Reading subtest over the two-year period. On the other hand, high-actives of high language ability had scores only slightly lower than nonhigh-actives, with differences that did not reach significance. Discussion centers on implications for further research and for educational interventions for hyperactive children.  相似文献

Toward Stewardship of Democratic Ideals: Using students' perspectives to improve school‐university collaboration and model democratic practice     

Corinne Mantle-Bromley  Ann M. Foster 《Teaching Education》2013,24(2):213-224

A healthy democracy values and depends on diverse perspectives to maintain flexibility and to make ongoing improvements that better serve its various groups. Our analysis of qualitative data from interviews conducted with students in two professional development school settings (school-university partnerships) showed that students were not regularly asked to provide their views of schooling or of school renewal efforts. The analysis further showed that students in this study, both young children and maturing adolescents alike, held personal knowledge that could contribute to adults' understandings of their work. The article is organized into five sections. First, we describe the innovation that provided the impetus for the study. Second, we describe the study's design. The third and fourth parts—students' perspectives on their schools and on the changes they were experiencing—represent the heart of the article. We conclude by placing the students' perspectives in the larger context of schooling for democracy—the theoretical framework for the study.  相似文献   

Exploring the educational aspirations–expectations gap in eighth grade students: implications for educational interventions and school reform     

Chris Michael Kirk  Rhonda K. Lewis  Angela Scott  Denise Wren  Corinne Nilsen  Deltha Q. Colvin 《Educational studies》2012,38(5):507-519

Over the past three decades, more and more students are expressing a desire to attend college, yet for many members of disenfranchised groups, this goal is often not attained. While many factors contribute to these disparities, research has shown that students begin adjusting their expectations (what they think they can achieve) for the future in relation to their idealised aspirations (what they would like to achieve). The current study explores this gap among 207 eighth grade students from two urban middle schools. Using the School Attitude Assessment Survey-Revised, three factors were found to predict expectations which matched student aspirations. These factors were academic motivation and self-regulating behaviours, academic self-perception and attitudes towards teachers. Implications for educational interventions and school reform are discussed.  相似文献

Dynamics of mirror writing compared to conventional writing in typical preliterate children     

Marine Portex  Carolane Hélin  Corinne Ponce  Jean-Noël Foulin 《Reading and writing》2018,31(6):1435-1448

In left-to-right writing cultures, spontaneous mirror writing of letters and digits in preliterate children appears more frequently on left-than right-facing characters. A compelling theory drawn on neuropsychological evidence of mirror generalization suggests that children resort to a right-orienting/writing rule when learning to write. The aim of the present study was to conceptually replicate and specify recent findings (Fischer, 2017a) on the predominant contribution of writing directionality to mirror writing in preliterate children. A training study was designed to compare on-line production of conventional versus mirror writing of 4-to-5 year-old French children (n?=?30). Over a 4-week period, children were taught to write from memory words and digits. During a subsequent writing-from-memory task, a spatial constraint (Cornell, 1985) was imposed to elicit paired conventional and mirror writing of the words/digits. Spatial and kinematic data were recorded through the use of a digital pen. The results indicate a main contribution of writing directionality to letter and digit reversals. Furthermore, kinematic equivalence between conventional and mirror writing supports the neurological mirror generalization process in children. Overall, these results constitute a further illustration that the manifestation of mirror writing in typically developing children is culture-bound.  相似文献
