本文利用2007-2014年我国88所高校的面板数据，采用系统广义矩（Sys-GMM）模型方法，实证研究了校企合作活动对我国高校科研绩效的影响，以及高校类型的调节作用。研究结果表明：（1）校企合作对高校科研绩效的影响呈倒U型；（2）高校类型对校企合作与高校科研绩效之间的倒U型曲线关系具有显著的负向调节作用。本研究不仅丰富了产学研合作理论，同时对高校制定及完善校企合作政策提供了理论参考。  相似文献   

School readiness of maltreated children: Associations of timing,type, and chronicity of maltreatment     

《Child abuse & neglect》2018

Children who have been maltreated during early childhood may experience a difficult transition into fulltime schooling, due to maladaptive development of the skills and abilities that are important for positive school adaptation. An understanding of how different dimensions of maltreatment relate to children’s school readiness is important for informing appropriate supports for maltreated children. In this study, the Australian Early Development Census scores of 19,203 children were linked to information on child maltreatment allegations (substantiated and unsubstantiated), including the type of alleged maltreatment, the timing of the allegation (infancy-toddlerhood or preschool), and the total number of allegations (chronicity). Children with a maltreatment allegation had increased odds of poor school readiness in cognitive and non-cognitive domains. Substantiated maltreatment was associated with poor social and emotional development in children, regardless of maltreatment type, timing, or chronicity. For children with unsubstantiated maltreatment allegations, developmental outcomes according to the type of alleged maltreatment were more heterogeneous; however, these children were also at risk of poor school readiness irrespective of the timing and/or chronicity of the alleged maltreatment. The findings suggest that all children with maltreatment allegations are at risk for poor school readiness; hence, these children may need additional support to increase the chance of a successful school transition. Interventions should commence prior to the start of school to mitigate early developmental difficulties that children with a history of maltreatment allegations may be experiencing, with the aim of reducing the incidence of continuing difficulties in the first year of school and beyond.  相似文献

不同信息条件下新型研发机构形成和作用机理研究——基于创新驱动发展的视角     

吴卫  陈雷霆 《科技管理研究》2018,(11)

以创新驱动发展为研究视角,界定承载研发创新功能的新型研发机构的内涵和形成动因,研究不同信息条件下新型研发机构的作用机理。通过建立数理分析模型发现,在完全信息条件下,通过组织间合作建立新型研发机构,各参与方能够获得经济收益和非经济收益,即使在没有经济收益的极端情况下,参与方也可以获得非经济收益,如学习能力、创新能力、管理能力的提升。在不完全信息条件下,创新研发风险越高,通过各方合作建立新型研发机构,获得的研发创新收益越大。并提出相关建议,以提高新型研发机构的创新能力。  相似文献   

观念与实践:高等师范院校美术教师教育课程类型组织探索     

李静 《美育学刊》2020,(2):8-13

随着我国教育改革不断推进,基础教育美术课程改革也进入深水区,美术教育发展面临许多新问题、新情况和新挑战,其中,要求美术教师专业化成为许多矛盾汇聚的焦点。在职美术教师的发展起点在于职前培养,而培养职前美术教师的关键之一是相关课程的设置与实施过程。故从我国学校美术课程观历史发展脉络出发,倡导建立美术课程内容与教育哲学观念、理解与实践之间紧密联系的观点,基于“实践智慧”,提出组织具有批判性质、经验性质和体验性质三种特点的高等师范学院美术教师教育课程模式设置与实施思路。  相似文献

Does your left hand know what your right hand is doing? Impacts of athletes’ pre-transgression philanthropic behavior on consumer post-transgression evaluation     

《Sport Management Review》2019,22(4):553-565

Despite the importance of an athlete’s image and reputation as an individual brand, the academic literature lacks investigations on whether and how an athlete’s brand can be protected when they engage in unethical transgressions. Focusing on athletes’ pro-social activities, the authors presented an experimental study to test how an athlete’s pro-social efforts can alleviate negative impacts from his/her transgression. In particular, the authors test the impacts of athletes’ involvement level (high vs. low) with a pro-social cause and level of fit between an athlete and a cause (high vs. low) on sport consumers’ perceptions. Results demonstrate that an athlete’s pre-scandal charitable behaviors can mitigate adverse impact of a transgression on consumer response only when the athlete has deeply engaged in charitable behaviors. The results also show that a higher fit between an athlete and a cause can generate more severe damaging impacts on consumer evaluation than a lower fit due to consumer skepticism caused by a combination between a negative reputation and a high-fit cause.  相似文献   

基于SWMM的地表径流量与城市下垫面和降雨特征关系的空间分析——以中国科学院大学雁栖湖校区为例     

罗英杰  张娜  李琪  王昕  景永才  乐荣武 《中国科学院大学学报》2020,37(1):27-38

以中国科学院大学雁栖湖校区为例，用城市雨洪管理模型（SWMM）模拟2016-2017年48场降雨事件中所有子汇水小区的径流过程；在验证可靠的基础上，探讨径流量空间分布与降雨和下垫面的关系，是开展防汛工作的重要基础。结果表明，径流量高值区多位于沥青小区，而低值区多位于绿地小区。沥青最易产流，绿地最不易产流。砌砖易产生中等量级的径流，混凝土较砌砖更易产流，但二者在不同降雨事件下的产流规律相似。沥青小区和砌砖小区的地表径流量均与坡度呈极显著或显著线性正相关关系。对沥青-砌砖和沥青-绿地小区，将非渗透面积比例（PIC）降至60%可明显控制其暴雨和大雨径流。要明显控制大暴雨径流，可将沥青-绿地小区的PIC降至30%以下；但降低PIC对沥青-砌砖小区大暴雨径流的控制作用不明显。研究结果可为海绵城市建设和城市内涝防洪提供理论依据和决策建议。  相似文献
