语篇中指称选择的认知语用解释

叙述语篇中的指称选择主要受到三个因素的影响:指称距离,指称对象是否引起歧义,指称对象与话题焦点的关系。这三个因素归根结底可以从心理学方面得到解释。人类的记忆系统和认知特点决定了人类对指称选择的认知加工方式。     

A characteristic function approach to the biased sampling model,with application to robust logistic regression

Many sampling problems from multiple populations can be considered under the semiparametric framework of the biased, or weighted, sampling model. Included under this framework is logistic regression under case–control sampling. For any model, atypical observations can greatly influence the maximum likelihood estimate of the parameters. Several robust alternatives have been proposed for the special case of logistic regression. However, some current techniques can exhibit poor behavior in many common situations. In this paper a new family of procedures are constructed to estimate the parameters in the semiparametric biased sampling model. The procedures incorporate a minimum distance approach, but are instead based on characteristic functions. The estimators can also be represented as the minimizers of quadratic forms in simple residuals, thus yielding straightforward computation. For the case of logistic regression, the resulting estimators are shown to be competitive with the existing robust approaches in terms of both robustness and efficiency, while maintaining affine equivariance. The approach is developed under the case–control sampling scheme, yet is shown to be applicable under prospective sampling logistic regression as well.     

文化差异、地理距离对我国各省分国别(地区）出口贸易的影响——基于空间面板数据的实证研究

利用2001-2009年中国30个省分分国别（地区）的出口贸易数据,采用空间探索性数据分析方法分析了各国及地区在我国的出口贸易空间格局,发现各国（地区）在我国的出口贸易中表现出较为显著的空间相关性。进一步,本文构建了考虑空间滞后因子的引力模型实证分析了文化差异和运输距离对我国各省分国别（地区）出口贸易的影响。研究结果表明：我国邻省出口对本省的空间溢出效应随着时间的推移不断增强;而邻省与本省在出口伙伴国选择上的“竞争效应”并不明显;文化差异在各国及地区在我国各省的出口贸易中所起的限制性作用表现突出;而陆运距离对各省分国别（地区）出口贸易的负向影响要明显大于海运距离,且随着时间的推移有不断扩大的迹象。     

心理期望：政治认同生成的内隐机制

政治认同是公民对国家政治诸要素所产生的一种心理上的归属感。心理期望作为政治认同的内隐机制,从需要因素看,可分为自发性政治认同需要和引致性政治认同需要。而对需要的满足,则取决于主体的自我政治期望和社会政治期望的契合程度及运行路向。现实问题往往因对期望的认知错位而产生各异的政治认同距离进而给个体和政府等带来心理压力。如何把这种压力保持在一定的安全阈值范围内而使政府和个人在期望心理供求方面处于大体均衡,成为优化政治认同效果的现实选择。     

Profit-oriented productivity change

This study develops an applicable profit-oriented productivity indicator when producers pursue profit maximization and can recognize input and output prices. We define the indicator, inspired by the Luenberger indicator and the Nerlovian efficiency measurement, in terms of both quantity distance functions and profit. Hence, the study׳s first stage decomposes the profit-oriented productivity change into two terms: profit efficiency change and profit technology change. Second, we decompose profit efficiency change into the changes in technical efficiency and allocative efficiency. Finally, profit technology change is separated into two components for capturing the shifts of technology and relative output/input prices. These decompositions provide a more complete picture of the sources of productivity change. We illustrate them with a sample of Taiwanese banks and compute the results using the models of directional distance functions.     

Combinatorial Equivalence of Fractional Factorial Designs

Two symmetrical fractional factorial designs are said to be combinatorially equivalent if one design can be obtained from another by reordering the runs, relabeling the factors and relabeling the levels of one or more factors. This article presents concepts of ordered distance frequency matrix, distance frequency vector, and reduced distance frequency vector for a design. Necessary conditions for two designs to be combinatorial equivalent based on these concepts are presented. A new algorithm based on the results obtained is proposed to check combinatorial non-equivalence of two factorial designs and several illustrating examples are provided.

交际法理论与实践间的偏差

自20世纪70年代以来,交际法因注重语言的意义,强调语言使用的得体性,而备受推崇。然而,其理论精髓“教学过程交际化和功能化”与我国的外语教学现状和资源不相吻合。理论与实践间存在偏差。不应盲目推崇。     

哲学如何面向现实?

哲学作为人类把握世界的一种基本方式,它必须以自己的特殊方式面向现实,才能实现哲学自身的发展并发挥哲学变革现实的独特作用。哲学面向的现实不是各种实例的总和,而是各个时代的时代精神。哲学不是以解释世界为目的而面向整个世界,而是以改变世界为旨趣而面向各个时代。哲学以反驳实践的方式而实现自身的改变世界的目的,并以自我批判的方式而实现自身的与时俱进。
