论社会公正与执政党政治权威

权威是人类社会关系中的一种普遍现象,也是社会秩序得以维持的必要机制。在我国现代化建设的过程中出现的如贫富分化、机会不均及司法不公正等社会问题,对我国执政党的政治权威产生了一定的弱化作用,民众对执政党政治权威的认同感降低。所以说新时期,维护社会公正,构建有效的制度安排,对于加强执政党政治权威具有重要意义。     

大数据税收征管对企业风险承担的影响研究

当前我国企业的风险承担处于较低水平,这给企业的可持续发展和国家的长期繁荣带来了极大的挑战。借助“金税三期”工程这一准自然实验,采用多期双重差分法研究了大数据税收征管对企业风险承担的影响及作用机制,研究表明：大数据税收征管对企业风险承担具有显著促进作用。机制检验发现,大数据税收征管通过抑制代理行为、缓解融资约束、增进税负公平、优化营商环境来促进企业风险承担。进一步的分析表明,大数据税收征管对非国有企业和有产业政策扶持企业风险承担的促进作用更大。

Inferences on correlation coefficients: One-sample,independent and correlated cases

This article concerns inference on the correlation coefficients of a multivariate normal distribution. Inferential procedures based on the concepts of generalized variables (GVs) and generalized p$p$-values are proposed for elements of a correlation matrix. For the simple correlation coefficient, the merits of the generalized confidence limits and other approximate methods are evaluated using a numerical study. The study indicates that the proposed generalized confidence limits are uniformly most accurate even for samples as small as three. The results are extended for comparing two independent correlations, overlapping and non-overlapping dependent correlations. For each problem, the properties of the GV approach and other asymptotic methods are evaluated using Monte Carlo simulation. The GV approach produces satisfactory results for all the problems considered. The methods are illustrated using a few practical examples.     

A Simple Approximate Procedure for Constructing Binomial and Poisson Tolerance Intervals

The problems of constructing tolerance intervals for the binomial and Poisson distributions are considered. Closed-form approximate equal-tailed tolerance intervals (that control percentages in both tails) are proposed for both distributions. Exact coverage probabilities and expected widths are evaluated for the proposed equal-tailed tolerance intervals and the existing intervals. Furthermore, an adjustment to the nominal confidence level is suggested so that an equal-tailed tolerance interval can be used as a tolerance interval which includes a specified proportion of the population, but does not necessarily control percentages in both tails. Comparison of such coverage-adjusted tolerance intervals with respect to coverage probabilities and expected widths indicates that the closed-form approximate tolerance intervals are comparable with others, and less conservative, with minimum coverage probabilities close to the nominal level in most cases. The approximate tolerance intervals are simple and easy to compute using a calculator, and they can be recommended for practical applications. The methods are illustrated using two practical examples.

试论河湟地区的民族地理学研究意义

"河湟"地区是中国西北多元民族文化共生的典型区域。"以水为据"梳理该地区少数民族聚落的分布特征,为该地区民族地理学研究提供了新的视角。河湟地区多元文化反映了西北民族文化分布格局,少数民族人口的时空变迁,少数民族文化与自然环境间的调试关系等,对于研究民族文化地理空间具有重要价值。河湟地区是整个西北民族走廊的重要组成部分,对于整个汉藏边界民族文化研究具有典型意义。     

河北省高校人文社科学报影响力分析

基于全国中文核心期刊、中国社会科学引文索引以及2009～2012年版中国期刊引证报告(扩刊版),对河北省高校人文社科学报的总体学术影响力进行了分析,结果表明,河北省高校人文社科学报的影响力较低,且有下降的趋势.河北省高校人文社科学报必须凸显文化传承与载体功能,依托地域优势结合省文化发展目标,提高学报论文质量,才能更好地为河北文化强省服务.     

从"超女"现象看构建和谐社会中媒体功能的发挥

"超女"借助于媒体,不仅为平民观众提供了娱乐狂欢,而且满足了人们多方面的心理需要.开放式海选所体现出的公平竞争精神、观众手机短信投票方式所蕴涵的和谐社会应具有的民主精神、超级女声大赛所喷发的社会活力,与构建社会主义和谐社会的目标是有联系的.和谐社会不仅需要媒体的积极参与和热情投入,更需要媒体用理性来把握、引导、发挥.传媒应该把握住这个生机勃勃时代的主旋律,去寻找那些真正能打动我们内心的人物和品质,去发现那些散发出理想主义芬芳的场景和故事,从而引发人们的感动,提升每个人的精神境界.
