高校思想政治教育与网络直播的链接研究

直播是近年来新兴的网络平台,以其泛娱乐化、即时交互强等特点吸引了近半数的网络流量,已成为高校思想政治教育 无法回避的领域。直播削弱了灌输教育的壁垒,加速了思想政治教育的传导与反馈,提升了思想政治教育的吸引力和感染力, 思想政治教育也应当“因时而进、因势而新、因形而活”,主动探索链接直播平台,这既是形势所迫,亦是价值所驱。通过优选载 体平台,创新内容形式,树立品牌合力等链接路径推动思想政治教育与直播平台有机结合,从而直面困境与挑战,最大限度地 实现链接价值,达到共赢目标。     

耦合网络边相继故障模型研究

针对耦合网络上频发的相继故障问题,通过分析边级联故障蔓延的动力学演化机制,构建耦合网络上边相继故障模型。以提高耦合网络整体抵制相继故障能力为出发点,依据不同度量指标,多角度分析具有不同耦合模式的耦合网络鲁棒性与模型参数之间的关联性,研究耦合网络间耦合模式和网络基本模型等因素对相继故障的影响,探讨耦合网络边相继故障模型的整体保护策略。研究结果表明,同配连接模式能够增强耦合网络抵制级联故障的鲁棒性;相互依赖的两个耦合网络之间拓扑结构越相似,网络抵制相继故障的鲁棒性越强;耦合网络鲁棒性与网络平均度正相关;适当的增加耦合网络间对称边数量,能够有效提高网络的鲁棒性。最后,应用边相继故障模型在耦合电力网络上进行实例分析。

重读伊拉克战争

伊拉克战争爆发至今已三年,但学界对其进行的深入探讨实际才刚刚开始。美国发动伊拉克战争的战略构想由来已久,并经历了从“遏伊倒萨”到“打伊倒萨”的过程。由于师出无名,这场战争始终存在着合法性危机。美国在不对称性战争中虽赢得了胜利,却最终使伊拉克丧失了和平。     

中国古代诗话及其汇编之体的承传

中国古代诗话的承传,主要体现在两大线索中:一、在单部诗话之体上,有"论诗及事"和"论诗及辞"之体的承传;二、在诗话汇编之体上,有分门类编之体和据人而编之体的承传.诗话体制的承传,从内在影响着我国古代诗话发展的走向,决定着古代诗话多方面价值的展开.     

ESTIMATION OF GUARANTEE TIME AND MEAN LIFE AFTER WARRANTY FOR TWO-PARAMETER EXPONENTIAL FAILURE MODEL

Suppose manufactured items have failure times distributed with the two-parameter exponential density function à-^le-(x-μ)/à (x≥μ≥0). The paper considers estimation of the guarantee time μ and mean life after warranty à. Properties of various estimators are given for both separate and simultaneous estimation of μ and à. Criteria for comparing estimators are entropy loss, LINEX loss, and (generalized) Pitman nearness.     

幼儿园开展游戏分享环节的现状及启示——基于江苏省幼儿园的调查

笔者通过问卷法、访谈法和观察法的综合运用,对江苏省的318名幼儿园教师进行了问卷调研,并选取N市某公立园的3个班级和6位教师作为观察和访谈对象。研究结果表明,在时间安排上,分享环节并非每次游戏后都会开展,不同年龄班的分享时长存在一定差异;在分享内容上,话题主要围绕角色游戏、结构游戏和美工游戏开展,更多涉及幼儿的社会领域发展经验,经常分享游戏中遇到的困难及解决策略;在开展形式上,不同年龄班游戏话题的开启方式各异,分享方法丰富多样,分享地点呈现多样化,但目前仍以全班讨论形式为主。据此,笔者从教师、园所和社会三个层面,提出了优化游戏分享环节开展现状的具体建议。     

Capturing the Spillover Effect With Multiplicative Error Models

Recent statistical models for the analysis of volatility in financial markets serve the purpose of incorporating the effect of other markets in their structure, in order to study the spillover or the contagion phenomena. Extending the Multiplicative Error Model we are able to capture these characteristics, under the assumption that the conditional mean of the volatility can be decomposed into the sum of one component representing the proper volatility of the time series analyzed, and other components, each representing the volatility transmitted from one other market. Each component follows a proper dynamics with elements that can be usefully interpreted. This particular decomposition allows to establish, each time, the contribution brought by each individual market to the global volatility of the market object of the analysis. We experiment this model with four stock indices.     

Weighted local linear composite quantile estimation for the case of general error distributions

It is known that for nonparametric regression, local linear composite quantile regression (local linear CQR) is a more competitive technique than classical local linear regression since it can significantly improve estimation efficiency under a class of non-normal and symmetric error distributions. However, this method only applies to symmetric errors because, without symmetric condition, the estimation bias is non-negligible and therefore the resulting estimator is inconsistent. In this paper, we propose a weighted local linear CQR method for general error conditions. This method applies to both symmetric and asymmetric random errors. Because of the use of weights, the estimation bias is eliminated asymptotically and the asymptotic normality is established. Furthermore, by minimizing asymptotic variance, the optimal weights are computed and consequently the optimal estimate (the most efficient estimate) is obtained. By comparing relative efficiency theoretically or numerically, we can ensure that the new estimation outperforms the local linear CQR estimation. Finite sample behaviors conducted by simulation studies further illustrate the theoretical findings.
