身处异代成相知尽在悠悠故国情——从朱彝尊对周密《绝妙好词》的接受说起

《词综》是浙西词派的理论代表。《词综》和《绝妙好词》在宗派意识和对“雅”词的崇尚方面，表现出极大的相似性。这表明，朱彝尊在编选《词综》时曾自觉接受周密《绝妙好词》的影响。其深层原因在于，浙西词宗朱彝尊和周密有相似的遗民情怀。     

Aggregating classifiers via Rademacher–Walsh polynomials

Methods are proposed to combine several individual classifiers in order to develop more accurate classification rules. The proposed algorithm uses Rademacher–Walsh polynomials to combine M (≥2) individual classifiers in a nonlinear way. The resulting classifier is optimal in the sense that its misclassification error rate is always less than, or equal to, that of each constituent classifier. A number of numerical examples (based on both real and simulated data) are also given. These examples demonstrate some new, and far-reaching, benefits of working with combined classifiers.     

家电下乡政策的消费效应评估——基于全国221个村庄的4年跟踪调查

以全国221个村庄所获得的4年调查数据作为研究基础,对"家电下乡"政策的消费效应予以评估和分析。调查表明,家电下乡政策消费效应的最大特征是农民消费需求的释放,其中包括全国消费总额的上升,户均消费额增幅达到8成,全国各地消费总量和户均消费数量的增加。但家电下乡政策的消费效应在实践中也遇到了持续性疲软的难题,如农民收入的限制作用,农民购买下乡产品比重偏低,政府补贴额和补贴程序不足,政策宣传和解说不到位。为了使家电下乡政策的消费效应持续起效,必须不断完善政策,使家电下乡政策的实惠真正落实到农民身上。     

Locally best invariant test for outliers in a gamma type distribution

It is shown that the locally best invariant test for the existence of outliers for scale parameters of the gamma distribution is given by Bartholomew's test for exponentiality which is the ratio of the sum of squares of the data to the square of the sample mean. The optimality robustness, including null and nonnull robustness of the test is shown. A small simulation study to compare the power among the other eight competitive tests for testing exponentiality is performed. It is seen that the locally best invariant test is not always best but is reasonably good. It is slightly better than Cochran's test and suffers less from the limiting masking effect.     

消费文化转型的激励机制与“两型社会”的构建

消费文化具有引导、凝聚和激励的社会效应,实现消费文化由传统向现代的转型,对于"资源节约型、环境友好型"社会的构建有着不可或缺的作用.因此,有必要在明确"两型社会"消费文化转型取向的基础上,探求消费文化转型的激励机制,以期对推动"两型社会"的构建进程有所裨益.

试论少数民族对北京传统民俗文化的影响

从辽代开始 ,北京逐渐成为北方乃至全国的政治、军事和文化中心 ,也成为边疆少数民族文化与中原汉族文化的交汇之地。北京的传统民俗文化 ,特别是服饰、饮食、居住、竞技娱乐、岁时节日等民俗文化 ,都曾深受少数民族 ,尤其是蒙、回、满等民族文化的影响 ,是多元一体中华民族文化的结晶与代表。     

论民族经济学的学科地位与作用

民族经济学于1979年创建,适应了中国多民族国家的国情与社会主义现代化建设需要,具有民族学与经济学的双重学科归属.这门由中国人自己创建的经济学分支学科,在学科理论建设、学术成果积累与专业人才培养方面取得了巨大成就.并通过不可取代的学科地位与鲜明的应用性特征,展现出民族经济学的发展前景.     

Strategic Learning and the Topology of Social Networks

We consider a group of strategic agents who must each repeatedly take one of two possible actions. They learn which of the two actions is preferable from initial private signals and by observing the actions of their neighbors in a social network. We show that the question of whether or not the agents learn efficiently depends on the topology of the social network. In particular, we identify a geometric “egalitarianism” condition on the social network that guarantees learning in infinite networks, or learning with high probability in large finite networks, in any equilibrium. We also give examples of nonegalitarian networks with equilibria in which learning fails.
