大学英语教学中中国文化缺失问题研究

当前,大学英语教学中的中国文化缺失问题日益严重,大多数英语学习者不能使用英语恰当地表述中国特色文化.研究在大学英语教学中融入中国文化的必要性,寻求大学英语教学与中国文化相结合的路径,有助于实现大学英语教学的最终目标,提高学生的英语综合应用能力和跨文化交际能力,进而提高国家的文化实力和世界影响力.     

Species richness,phylogenetic and functional structure of bird communities in Chinese university campuses are associated with divergent variables

University campus is an important component of urban landscapes for biodiversity conservation. However, to our knowledge no study has quantitatively assessed the diversity and structure of bird communities in Chinese university campuses, especially from phylogenetic and functional perspectives. Here, for the first time we linked species richness, phylogenetic structure and body mass structure of campus bird communities with contemporary climate, glacial-interglacial climate change, altitudinal range, population density around campus, area and age of campus to test their associations. We found 393 bird species in 38 university campuses (29% of all Chinese bird species, two species are endangered, four species are vulnerable, and 33 species are near threatened). The variables significantly correlated with campus bird species richness, phylogenetic structure and body mass structure were altitudinal range and mean annual precipitation, glacial-interglacial anomaly in temperature, and altitudinal range, respectively. In particular, there were more species in steeper and wetter campuses, more young species clustered in campuses with stable glacial-interglacial climate, and more species with smaller body size in steeper campuses. Our study highlights the importance of considering both phylogenetic and functional information for biodiversity conservation in urban ecosystems.     

木偶戏剧在幼儿园活动中运用存在的问题与对策——以山西孝义木偶戏剧为例

木偶戏剧既是我国优秀的非物质文化遗产，同时也是丰富幼儿认知、开阔幼儿眼界的重要教育资源。当前运用木偶戏剧资源开展相关活动的幼儿园数量相对较少，在有限的应用当中也存在教师自身对利用木偶戏剧资源认识不足，木偶戏剧资源利用表面化及形式化等一系列问题。本文根据孝义木偶戏剧独有的艺术特点，从木偶戏剧的欣赏活动、表演活动与制作活动三方面，对如何将孝义木偶戏剧应用到幼儿园活动进行了探讨，为幼儿园运用孝义木偶戏剧这一文化资源组织相关活动提出具体建议。

《泰王国民商法典》制定的历史背景

《泰王国民商法典》是在近代泰国法制改革的大背景下产生的，有着复杂的社会历史背景。曼谷王朝拉玛四世以前，泰国历经素可泰王朝、大城王朝和曼谷王朝的一部分，朝代更迭，历时漫长但在法制上却保持了相对稳定。1851年，曼谷王朝四世王拉玛四世（1851-1868）登基，拉开了泰国近代史的序幕。1852年1月，英国在第二次英缅战争之后，占领了缅甸，并觊觎泰国。1855年，英国派其驻香港的总督鲍林率使团到泰国与拉玛四世谈判，威逼泰国于1855年4月18日签订了《英暹条约》（史称《鲍林条约》）。这一个不平等条约彻底打开了泰国闭关自守的大门，欧洲列强以该条约为蓝本，威逼泰国签订了类似条约。泰国自此成为一个半殖民地国家，其法制也逐步西化，泰国的法制也这一时期完成了从古代法制向现代法制的转型。事实上，泰国法制现代化的过程，就是一个从理论到制度逐步西化的过程。《泰王国民商法典》就是在这样一个大的背景下产生的。     

多产品救援物资的储备决策:一个扩展的Newsvendor模型

储备一定数量的救援物资用于应对可能的灾害事件对于改善救援工作的绩效有着重要的意义。在考虑救援组织机构面对多种可能的灾害事件的基础上，本文利用一个二阶段交付过程模型来刻画灾害事件发生后救援物资的交付。该模型明确救灾组织在灾害事件发生后首先交付储备物资，如果需求短缺则再综合利用社会捐赠物资和应急采购满足剩余需求。以期望总成本最小化为目标，在需求全部被满足的前提下，本文建立了多产品救援物资的储备决策模型，并给出了其最优解的隐函数形式。进一步，考虑救灾物资储备存在预算限制，研究了具有预算限制的多产品救援物资储备决策模型，并设计了一种二分法的求解算法。数值算例的计算结果则对所建立模型及算法进行了检验。     

No Room for Respectability: Boundary Work in Interaction at a Shanghai Rental

This article examines the dramaturgical challenges of doing boundary work for a group of college women living with non‐college women at an overcrowded rental. To regulate tenant conduct and maintain their sense of self‐worth, the college women engaged in defensive othering and constructed their identity as “high‐quality” people on the basis of their characterization of their less‐educated roommates as “low‐quality” people. Their strategy of gaining self‐worth at their roommates' expense violated basic rules of social interaction that require participants to give face to gain face. This study shows that, in addition to weakening group solidarity and reproducing social inequalities, defensive othering also undermines subordinates' effort to gain self‐worth in the co‐presence of other subordinates.

网络环境下的消费者态度转变——基于在线口碑信息框架交互作用的实验研究

关于在线口碑的影响问题,以往研究者已从不同的角度给出不同的解释.但是,他们的研究结论并不一致且忽视两个问题:消费者接收在线口碑之前的初始态度会影响对信息的过滤;产品销量并不等价于消费者态度.本研究尝试从态度改变的角度研究在线口碑如何影响消费者决策这一问题,考虑初始态度和认知需求的调节作用,将产品属性作为实验控制变量,归纳不同类型消费者的有效在线口碑信息框架类型.最后,提出一个消费者分类及其信息传播策略矩阵,为企业销售方的信息传播管理提供参考.主要结论有:自我强化型应定期进行正面要点信息沟通;理性说服型可进行正面要点信息改变初始期望,同时控制负面信息的扩散;摇摆不定型可根据产品属性采用不同的信息表述方式;消极排斥型应选择减少投入.     

Estimation of the additive hazards model with interval-censored data and missing covariates

The additive hazards model is one of the most commonly used regression models in the analysis of failure time data and many methods have been developed for its inference in various situations. However, no established estimation procedure exists when there are covariates with missing values and the observed responses are interval-censored; both types of complications arise in various settings including demographic, epidemiological, financial, medical and sociological studies. To address this deficiency, we propose several inverse probability weight-based and reweighting-based estimation procedures for the situation where covariate values are missing at random. The resulting estimators of regression model parameters are shown to be consistent and asymptotically normal. The numerical results that we report from a simulation study suggest that the proposed methods work well in practical situations. An application to a childhood cancer survival study is provided.
