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.     

元代回回人的宗教制度与伊斯兰教法

本文研究了元代回回社会中的宗教制度和伊斯兰教法。作者认为,元代回回社会中存在着官方认可的管理者和更小的民间宗教事务管理者两套系统。伊斯兰教法约束了回回人的行为规范,并且对元代多元法律文化的形成产生了影响。在多元文化的发展过程中,“回回法”同“汉法”及“蒙古法”有一个冲突和融合的过程。     

Implementing Monte Carlo tests with p-value buckets

Software packages usually report the results of statistical tests using p-values. Users often interpret these values by comparing them with standard thresholds, for example, 0.1, 1, and 5%, which is sometimes reinforced by a star rating (***, **, and *, respectively). We consider an arbitrary statistical test whose p-value p is not available explicitly, but can be approximated by Monte Carlo samples, for example, by bootstrap or permutation tests. The standard implementation of such tests usually draws a fixed number of samples to approximate p. However, the probability that the exact and the approximated p-value lie on different sides of a threshold (the resampling risk) can be high, particularly for p-values close to a threshold. We present a method to overcome this. We consider a finite set of user-specified intervals that cover [0, 1] and that can be overlapping. We call these p-value buckets. We present algorithms that, with arbitrarily high probability, return a p-value bucket containing p. We prove that for both a bounded resampling risk and a finite runtime, overlapping buckets need to be employed, and that our methods both bound the resampling risk and guarantee a finite runtime for such overlapping buckets. To interpret decisions with overlapping buckets, we propose an extension of the star rating system. We demonstrate that our methods are suitable for use in standard software, including for low p-value thresholds occurring in multiple testing settings, and that they can be computationally more efficient than standard implementations.     

A strong law of large numbers for independent random variables under non-additive probabilities

Abstract

Under non‐additive probabilities, cluster points of the empirical average have been proved to quasi-surely fall into the interval constructed by either the lower and upper expectations or the lower and upper Choquet expectations. In this paper, based on the initiated notion of independence, we obtain a different Marcinkiewicz-Zygmund type strong law of large numbers. Then the Kolmogorov type strong law of large numbers can be derived from it directly, stating that the closed interval between the lower and upper expectations is the smallest one that covers cluster points of the empirical average quasi-surely.     

舆论领袖传播影响力的阶段式建模分析

在网络社会,无论是网络推手炒作谣言,还是官方微博积极应对,都可视作舆论领袖在舆情演化过程中发挥传播影响力。本文将舆情演化过程分为两个阶段,在两个阶段分别应用不同的仿真模型对不同作用舆论领袖的传播影响力进行分析。第一个阶段是舆情危机爆发阶段,即舆情危机"从无到有",分析网络推手在该阶段的扩散影响力,以SIR经典传染病模型为基础,构建包含有网络推手作用的扩散影响力模型;第二个阶段是舆情危机平息阶段,即舆情危机"从有到无",分析官方微博在该阶段的证伪影响力,以Lotka-Volterra竞争关系模型为基础,研究官方微博如何发挥证伪影响力与网络推手进行博弈。结合具体舆情实例对阶段式模型进行验证分析,并提出如何根据舆论领袖不同传播作用应对舆情危机相关政策建议,以期帮助决策者打击网络谣言、平息舆情危机。

基于微信平台艺术品拍卖的对策与建议

近年来,艺术品的微信拍卖逐渐成为人们热议的一个话题。2014年3月,“艺麦微拍”推出的朱新建的《美人图》以16.1万元的价格成交,创下微信平台拍卖艺术品的最高纪录。随着中国新媒体发展进一步呈现移动化、融合化和社会化加速的态势,微信拍卖的群体也在迅速扩大。一方面,微拍的现象越来越普遍,另一方面,作为一种新型的拍卖方式也饱受人们争议。由此探讨了艺术品微信拍卖的优势和存在的一些问题,在此基础之上结合实际情况提出了一些具体的对策与建议。     

简论古典戏曲中的“速配”现象

"速配"在古典戏曲中普遍存在,且其速度令人惊诧。究其原因,有以下几点:首先,古代礼教的严苛挤压了青年男女从容恋爱的空间,使得偶然的邂逅变成了千载难逢的旷世一遇。其次,本能压抑之后的非常方式的爆发也是促成速配的重要因素。再次,才色相倾的交往模式使得速配成为可能。同时,速配很容易构成剧情悬疑,引发观众的观赏兴趣。最后,速配作为"传奇"之"奇",在戏剧中往往可以形成"夺目"的艺术效果。
