学习型社会背景下成人终身学习模式探究     

王矗  陈琳 《成人教育》2011,(10):19-22

构建成人终身学习的学习型社会是我国全面建设小康社会的重要目标。学习型社会为成人学习者提供了一个良好的终身学习环境,促进了成人学习不断向全民化、终身化方向发展。通过成人学习者与普通学生不同的心理特征和学习特征的对比分析,结合终身学习的特点提出了成人终身学习的四个模式,即主动式学习模式、发现式学习模式、合作式学习模式、开放式学习模式。最后,在四个模式的基础上进行分析和探讨。  相似文献

Measuring scientific contributions with modified fractional counting     

Gunnar Sivertsen  Ronald Rousseau  Lin Zhang 《Journal of Informetrics》2019,13(2):679-694

We develop and propose a new counting method at the aggregate level for contributions to scientific publications called modified fractional counting (MFC). We show that, compared to traditional complete-normalized fractional counting, it eliminates the extreme differences in contributions over time that otherwise occur between scientists that mainly publish alone or in small groups and those that publish with large groups of co-authors. As an extra benefit we find that scientists in different areas of research turn out to have comparable average contributions to scientific articles. We test the method on scientists at Norway’s largest universities and find that, at an aggregate level, it indeed supports comparability across different co-authorship practices as well as between areas of research. MFC is thereby useful whenever the research output from institutions with different research profiles are compared, as e.g., in the Leiden Ranking. Finally, as MFC is actually a family of indicators, depending on a sensitivity parameter, it can be adapted to the circumstances.  相似文献   

孔隙分布不均匀性对渗透率影响的MRTLBM法研究     

马斌  史琳  黄超  许强辉 《中国科学院大学学报》2018,35(2):193-199

孔隙率与渗透率是多孔介质非常重要的属性参数,采用MRT LBM研究孔隙率损失与渗透率损失相关性以及同孔隙率异构孔隙对渗透率特性的影响。结果表明：当存在使孔隙率均匀变小的沉积、沉降或结焦等因素时,渗透率损失率是孔隙率损失率的2倍左右;同孔隙率异构多孔体中,渗透率有巨大差异;同孔隙率异构多孔体中最大孔喉最小孔喉比越大渗透率越小;同孔隙率多孔体中迂曲度越大渗透率越小。  相似文献   

Mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems     

Yu Lin  Yu Zhang  Anthony Bloch 《Journal of The Franklin Institute》2021,358(4):2453-2481

In this paper, the problem of mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems is investigated. By using stochastic Lyapunov functions together with Razumikhin technique, some sufficient conditions for mean-square integral input-to-state stability for a class of nonlinear impulsive semi-Markov jump delay systems are developed. In particular, the results obtained generalize and complement some recent literature. Finally, some numerical examples are given to show the effectiveness and advantages of the proposed techniques.  相似文献   

Linear quadratic open-loop Stackelberg game for stochastic systems with Poisson jumps     

Yaning Lin 《Journal of The Franklin Institute》2021,358(10):5262-5280

This paper is concerned with the finite horizon linear quadratic (LQ) Stackelberg game for stochastic systems with Poisson jumps under the open-loop information structure. First, the follower solves a LQ stochastic optimal control problem with Poisson jumps. With the aid of an introduced generalized differential Riccati equation with Poisson jumps (GDREP), the sufficient conditions for the optimization of the follower are put forward. Then, the leader faces an optimal control problem for a forward-backward stochastic differential equation with Poisson jumps (FBSDEP). By introducing new state and costate variables, a sufficient condition for the existence and uniqueness of the open-loop Stackelberg strategies is presented in terms of the solvability of two differential Riccati equations and a convexity condition. In addition, the state feedback representation of the open-loop Stackelberg strategies is obtained via the related differential Riccati equation. Finally, two examples shed light on the effectiveness of the obtained results.  相似文献   

Adaptive output feedback fault tolerant control for uncertain nonlinear systems based on actuator switching     

Chen Sun  Yan Lin 《Journal of The Franklin Institute》2021,358(11):5722-5749

In this paper, an adaptive output feedback fault tolerant control (FTC) based on actuator switching is proposed for a class of single-input single-output (SISO) nonlinear systems with uncertain parameters and possible actuator failures, for which a set of healthy actuators are available as backups. While high-gain K-filters are utilized to estimate the unmeasured states, an adaptive control law is designed to compensate for the parameter uncertainties and certain actuator failures, an actuator switching strategy based on a set of appropriately designed monitoring functions (MFs) is proposed to tackle those serious actuator failures, make tracking error satisfy prescribed transient and steady-state performance and guarantee closed-loop signal boundedness.  相似文献

本研究以调查问卷的形式随机抽取了250名台州学院大学生,对其上网时间长短与气质类型进行调查。结果表明,气质类型会影响大学生上网时间的长短,具有外倾气质类型（如多血质和胆汁质）的大学生平均每周上网时间要小于具有内倾气质类型（如粘液质与抑郁质）的大学生。  相似文献   

电大参与社区老年教育实践初探——以温州社区大学老年教育为例     

蔡钒  林志良 《厦门广播电视大学学报》2011,14(1):8-12

随着银发浪潮的来临,老年教育越来越受到人们的关注。在建设全民学习、终身学习的学习型社会背景下,社区教育在老年教育方面发挥了较大的作用。电大基于开放教育的教学模式在社区老年教育领域有着天然的优势,在师资力量、社会认可、政府支持、硬件设施、网络覆盖等方面较其他办学主体都更胜一筹。但在宣传力度、教学管理、设施设备、普及社区老年教育上都还存在不足。如何进一步提高教学质量、丰富教学内容,为更多的老年人提供更优质的教学服务等方面还有很多问题值得社区教育工作者共同探讨。目前我国的社区老年教育仅限于闲暇教育,随着社会经济的发展、物质文化生活水平的提高,对老年人的继续教育、补偿教育应该未雨绸缪,及早规划。  相似文献
