This study investigated whether the associations between parental distress with conduct problems (CPs) and prosocial behaviors (PBs) are moderated by children's skin conductance (SC) and heart rate (HR) reactivity to fear. Participants were 147 Greek-Cypriot children (Mage = 7.30, 44.2% girls), selected from a larger screening sample (data were collected from 2015 to 2018). Longitudinal associations suggested that children with high HR reactivity to fear were more likely to display PB, whereas those with low SC reactivity were more likely to engage in CP behaviors. In contrast, interaction effects suggested that children high on SC reactivity to fear were more susceptible to the effects of parental distress, as indicated by their higher vulnerability to engage in CP (cross-sectionally) behaviors and their lower scores on PB (cross-sectionally and longitudinally). 相似文献

Breaking the Ivory Tower: Academic Entrepreneurship in the Life Sciences in UK and Germany 总被引：1，自引：0，他引：1
We examine engagement in commercial activities (consulting, patenting, and founding) among more than 2200 German and UK life scientists. We test hypotheses that include attributes of individuals, their material and social resources, and perceptions about values and reputation. We find that characteristics reflecting professional security, advantage and productivity are strong predictors for a greater breadth of participation in academic entrepreneurship, but not for all forms of technology transfer that we are able to test. For such academics, science and commerce go hand in hand, as they are best poised to straddle the boundary between industry and academy. We find strong support, however, that scientists perceive the value of patenting differently, and the level of reputational importance placed on scientific compared to commercial achievements matters in shaping commercial involvement. 相似文献

基于CLUE-S模型和Markov模型的城镇土地利用变化模拟预测——以江苏省常熟市辛庄镇为例 总被引：11，自引：1，他引：10
基于高分辨率遥感影像解译得到江苏省常熟市辛庄镇4期土地利用历史数据,首先对CLUE～S模型的预测精度进行验证,然后利用CLUE—S模型和Markov模型相结合的方法对研究区未来土地利用变化进行3种不同情景的模拟预测,并系统分析了各情景下土地利用变化的时空特征。结果表明,CLUE—S模型在乡镇小尺度的土地利用变化模拟预测效果较好,精度较高。各情景下,建设用地的快速增长仍将在未来的土地利用变化中占据主导地位,且均以消耗大量的水田为代价,河流密布、交通便捷和经济发达的区域将是未来耕地非农化的“热点”区域。生态保护情景和基本农田保护情景对未来土地利用变化的调控效果较好,林地、水体、水田和旱地受到了更好的保护,并在一定程度上抑制了建设用地的肆意蔓延。 相似文献

为了确保新建隧道对近接既有隧道的施工安全性,依托北京新机场线上跨既有地铁10号线工程,对新建隧道的加固方案进行优化研究.通过有限差分数值软件,对新建隧道上半环注浆、新建隧道下半环注浆以及新建隧道全环注浆等3种加固措施进行数值模拟分析.研究表明:新建隧道上半环注浆仅能有效降低路面及既有结构的变形;下半环注浆仅能有效控制既有隧道的结构变形;全环注浆能有效地控制地表沉降及既有隧道结构的变形.研究内容可为新建隧道近接既有隧道施工的相关研究提供参考. 相似文献

Batsheva Guy Tziporah Feldman Caroline Cain Lauren Leesman Chara Hood 《Educational Action Research》2020,28(1):142-153
ABSTRACTWhile the ‘action’ portion of a Participatory Action Research (PAR) project is a crucial component of the process, action tends to be challenging to define, achieve, and measure. The current paper both defines and describes action within the context of a particular PAR collaboration and explores the process and challenges of navigating and implementing action in a PAR project. The specific PAR project detailed in this paper was executed within a higher education setting and involves a group of undergraduate women co-researchers studying their experiences in STEM (Science, Technology, Engineering, and Mathematics) fields. 相似文献
