Can a floating collection thrive in a large multicampus academic research library? Floating collections have been successful in public libraries for some time, but it is uncommon for academic libraries and unheard of for a large academic library system. This article will discuss the investigation into the feasibility of a floating collection at Penn State University Libraries, its implementation, and continuation for a period covering 2009 through 2015. Attaining the floating collection, limited to monographs in the general stacks of campus libraries, proved to be easier to implement than imagined and resulted in unintended benefits as well as some surprises. 相似文献

企业创新是建设创新型国家的重要途径之一,如何有效地提升实体经济的企业创新能力,是目前亟待解决的问题。本文以2007-2017年我国A股上市公司的数据为研究样本,系统地考察了董责险对于企业创新的影响。研究表明,企业购买董责险能够提升企业的风险承担水平,从而显著促进企业创新。进一步地,本文发现国有上市公司、股权集中度较低的上市公司、非两职合一的上市公司购买董责险对企业创新的影响更为显著;高新技术行业上市公司以及市场化程度高地区上市公司购买董责险对企业创新的促进作用更为显著。此外,本文还发现,当企业面临的外部诉讼环境风险程度较低时,也更容易通过购买董责险促进企业的创新行为。本文的研究有利于检验董责险对于企业创新的促进作用,以及其背后的作用机制,对促进企业创新能力的提升具有重要的政策意义。 相似文献

以实证方法研究了股东与经理人之间的信任度、经理人风险承担、股东与经理人之间的信息不对称及企业创新绩效的关系。研究表明,股东与经理人的信任度越高,越有利于企业创新绩效的提高,股东与经理人的信任度对企业创新绩效有直接影响。股东与经理人信任度越高,经理人的风险承担意愿越强。经理人的风险承担意愿对企业创新绩效有正向影响。股东与经理人之间的信任度可以通过经理人的风险承担间接影响企业的创新绩效。信息不对称度的降低可以提高股东与经理人之间信任度对企业创新绩效的直接促进作用。本研究对现有的部分理论做出了有益的补充,为企业实践提供了一定的参考。 相似文献

Professional learning is intended to improve teaching, benefit student learning and in the longer term improve achievement of targets in schools. When teachers take responsibility not only for their own learning but also for their colleagues’, it can lead to a shift in attitudes towards collaborative learning. This study presents an example of a professional learning community (PLC) based on teachers’ engagement in systematic inquiries. The aim of the study was to explore crucial factors during the process of critical friendship that could be related to a PLC. The research context was a series of shadowing sessions where teachers were expected to document teaching and provide feedback. The analyses are mainly based on documentation, in the form of shadowing logs produced when teachers study each other in action. Findings indicate that the role of critical friend was hard to internalise and that most of the teachers did not use it to its full potential for learning, according to the Vygotskian concept of the zone of proximal development. Three crucial factors for learning in a PLC are addressed: active choices related to teachers’ and students’ learning during different phases in the inquiry; the complexity of mastering several skills in action research at the same time; and the teachers’ attitudes to professional learning. 相似文献

基于进化心理学的相关理论,采用单类内隐联想测验（SC-IAT）探讨男女性对冒险行为信息的加工机制。结果发现,以反应时作为判断标准时,仅男性存在内隐联结效应,内隐效应的性别主效应显著,领域主效应不显著;进一步分析D分数发现两性均出现内隐联结效应,性别、领域主效应不显著。可见,冒险行为信息与求偶动机存在内隐联结,男女两性对冒险行为信息的加工存在一定的差异;两种领域的冒险行为信息对内隐联结效应不产生影响。 相似文献

单一采用交付主义原则很难适应错综复杂的经济生活。我国《合同法》应区分交付与所有权转移不同步的原因，只有在所有权保留买卖中可采用交付主义原则，而在其他情况下应采用物主负担风险原则。尤其必须明确的是，在商品房买卖合同中，除了开发商采用保留所有权的担保形式，其他交易方式包括一次性付款、按揭等等都应采用物主负担风险原则。 相似文献

Child characteristics including age, gender, risk-taking behaviour and sensation seeking are thought to influence children's ability to appraise risks. The present study investigated children's risk perceptions and appraisals in the context of common outdoor physical play activities. Risk perceptions and appraisal of four- and five-year olds were assessed using a pictorial risk appraisal measure and through individual semi-structured interviews examining children's decision-making. Sensation seeking and risk-taking behaviour were assessed using self- and parent-report measures. Results revealed that the children were able to identify injury risk behaviours however differentiating the severity of the potential injury was less accurate. Furthermore, the children appeared to use these judgements in their play to inform their behaviour whilst using playground equipment. Whilst they actively sought out those activities that offered challenge and excitement, they were aware of their abilities and showed caution in engaging in activities that were beyond their current capabilities. The results have implications for the provision of calculated risk-taking in outdoor play and for adult responses to the risk-taking behaviour of children. 相似文献

厘清风险投资、企业风险承担和企业创新投资决策间的关系,对提升企业风险承担水平,增强企业创新积极性,促进我国创新创业事业健康发展具有重要意义。本文通过构建企业家、风险投资与银行三方动态博弈模型,分析了风险投资对企业风险承担的作用机理,基于2007至2018年我国A股上市公司数据进行了实证研究,并运用“情景转换回归”方法对本文提出的假说进行了稳健性检验。研究表明：风险投资能够促进企业风险承担;高持股比例、联合投资、高声誉风险投资对企业风险承担的激励作用更为明显。进一步研究发现：提升企业治理能力,减轻企业融资约束是风险投资影响企业风险承担的重要渠道。企业风险承担水平的提升将刺激企业研发和技术并购,企业风险承担在风险投资与企业创新投资决策间发挥着中介作用。 相似文献

School connectedness has been shown to be an important protective factor in adolescent development, which is associated with reduced risk-taking behavior. Interventions to increase students’ connectedness to school commonly incorporate aspects of teacher training. To date, however, research on connectedness has largely been based on student survey data, with no reported research addressing teachers’ perceptions of students’ connectedness and its association with student behavior. This research attempted to address this gap in the literature through in-depth interviews with 14 school teachers and staff from two Australian high schools. Findings showed that teachers perceived students’ connectedness to be important in regard to reducing problem behavior, and discussed aspects of connectedness, including fairness and discipline, feeling valued, belonging and having teacher support, and being successfully engaged in school, as being particularly important. This research enables the development of school-based intervention programs that are based on both student- and teacher-focused research. 相似文献
