新形势下高校奖学助学的标准及其实施研究     

王明对  龙志军 《九江职业技术学院学报》2015,(2)

我国高校资助政策体系应从无偿资助为主向有偿资助、奖励资助转变。扩大有偿资助比例和范围,加大奖学金资助力度,减少无偿资助。既要发挥资助体系的扶贫解困功能,还要发挥其教育功能。  相似文献   

六维三次超混沌系统及其在图像加密中的应用     

张大庆  朱建良 《宁波职业技术学院学报》2013,(4):79-82

由于超混沌系统的混沌特性更为复杂,所以高维数的超混沌系统的设计已经成为混沌理论研究的一个新方向。在四维和五维混沌系统的基础上构造了六维三次超混沌系统,李雅谱诺夫指数计算和Matlab仿真结果证明该系统具有超混沌特性;同时设计了相应的硬件实现电路,并对其进行Multisim仿真,所得到的结果与系统的Matlab仿真结果完全一致,都呈现出了相同的混沌吸引子,说明了该系统的可实现性,最后利用该混沌信号源完成了图像的加密和解密,实现了保密通信的应用。  相似文献   

Instructional practices in secondary science: How teachers achieve local and standards-based success     

Beth A. Covitt  Elizabeth Xeng de los Santos  Qinyun Lin  Christie Morrison Thomas  Charles W. Anderson 《科学教学研究杂志》2024,61(1):170-202

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献   

Team learning in IT implementation projects: Antecedents and consequences     

Ali E. Akgün  Gary S. Lynn  Halit Keskin  Derya Dogan 《International Journal of Information Management》2014

This study investigates the antecedents and consequences of team learning, which is composed of information acquisition, dissemination, and implementation, in information technology (IT) implementation projects. By investigating 129 IT implementation project teams, we found that (1) information acquisition and information dissemination have a positive impact on project outcomes, such as speed-to-users, lower implementation cost, and operational effectiveness, and (2) team behavior and enabler variables, such as teamwork, team communication, interpersonal trust between team members, team commitment, and senior manager support, positively influence team learning. We also found that team anxiety moderates the relationship between team learning and project outcomes.  相似文献   

Organizational identity challenges in a post-merger context: A case study of an information system implementation project     

Dragos Vieru  Suzanne Rivard 《International Journal of Information Management》2014

This study examines the effects of the differences in organizational identities that emerged during a post-merger project that aimed at unifying the laboratory services of a large healthcare center that resulted from the merging of three hospitals by supporting them with a unique information system. We draw on the concepts of organizational identity and sensemaking to analyze the laboratory information system implementation project. Organizational identity is conceptualized as the mental representation that organizational members have of themselves as a social group in terms of practices, norms, and values and how they understand themselves to be different from members of other organizations. Data analysis suggests that divergent organizational identities and team members’ alternative interpretations of others’ practices, norms and organizational symbols, coexist during the post-merger integration phase. These interpretations are reflected in the final functionality of the information system that was different from the planned one.  相似文献   

绿色增长战略实施能力体系研究          下载免费PDF全文

张旭  杜瑶 《科研管理》2014,35(12):153-159

构建完善的绿色增长战略实施能力体系是实施绿色增长战略,实现战略目标的保障。本文通过对绿色增长及绿色增长战略相关文献的分析,从战略实施的角度识别了绿色增长战略的参与者。通过分析参与者能力要素及其相互关系,构建了绿色增长战略实施的能力体系。研究认为,只有充分发挥各能力要素间的协同作用,才能有效实施绿色增长战略。这需要政府引导企业行为及绿色消费,公众充分参与政府绿色决策,市场培育绿色能力。在此基础上,企业利用政府支持之手,满足消费者绿色需求,实现环境和经济的双赢。  相似文献
