《谢尔曼反托拉斯法》的普通法条款选择及其政治意图

《谢尔曼反托拉斯法》放弃最初的“竞争”条款,意图通过政治干预,保护中小生产者的市场定价权力,缓解其面临的工业化困境。而选择普通法内容,则意在解决国家政治救助途径的宪法局限。     

论世情小说教主冯梦龙的小说雅俗观——江南世情小说雅俗系列研究之一

雅与俗是中国文学乃至文化批评史上的重要概念之一,在具体的批评实践中有着政治的、道德伦理的、文化的、文学的、艺术的等丰富内涵,雅俗不仅仅是衡量文学作品的重要标准,也是衡量文化与社会乃至人、事、物的重要标准。雅俗问题是冯梦龙＂三言＂研究的核心问题,雅就是道心、天理,俗就是人心、人欲。冯梦龙提倡＂奏雅＂与＂适俗＂并重,大力提高小说的地位,其＂三言＂的成功带动了世情小说持续的热潮,《型世言》、《石点头》、《豆棚闲话》,特别是《红楼梦》等一大批世情小说杰作相继问世,冯梦龙不愧为世情小说的伟大先驱与教主。     

Asymptotic Inference on Cointegrating Rank in Partial Systems

The likelihood ratio test for cointegrating rank is analyzed for partial (or conditional) systems in the vector autoregressive error-correction model. Under the assumption of weak exogeneity for the cointegrating parameters, the asymptotic distributions are given and tables of critical values are provided. A discussion is given of some of the assumptions of the model, why they are needed, and how they are tested.     

近代日本民间团体的对华政策理念--以东亚同文会的"中国保全"为中心

19世纪末,东亚同文会基于地缘政治和日本扩张在华权益的需要,为应对中国的瓜分危机祸及日本的局面提出“中国保全”的对华政策理念;至义和团事变,出于乘乱控制中国南方的需要,这个理念演变为“联邦保全”;“九.一八”事变发生后,该会为使日本的侵略正当化炮制了“亚洲保全”的新理念。日本对华政策理念的转变过程受国家利益的左右和驱动,这在近代日本民间团体的对华政策活动中颇具典型性。     

审美“共通感”释疑

审美判断的"共通感"问题,涉及的是一个审美对象的客观性与主体审美的主观性之间的矛盾问题。如果我们找不到通达各主体之间的公共桥梁,那么,是不可能真正解决审美对象的"客观性"与主体审美的"主观性"这一矛盾的。这就需要尝试引入一个新概念——"精神青春期"。要理解各主体之间审美判断中的"共通感"问题,非"精神青春期"概念莫属;"精神青春期"概念的引入,为我们真正解决审美对象的"客观性"与主体审美的"主观性"这一矛盾提供了可能。     

基于平等权的共同富裕制度设计分析

贫富差距过大是目前中国面临的一个突出的社会问题,然而人们多局限在收入分配层面寻找解决问题的办法,没有抓住问题的实质。应进一步探寻解决问题的思路,从保障平等权入手进行顶层设计,保障机会均等、起点平等、规则公平、调剂到位、结果公正,为每个社会成员提供平等的发展机会,才能切实解决贫富差距过大问题,以达到共同富裕。     

Estimating Quantiles of Normal Populations with a Common Mean

Suppose independent random samples are available from two normal populations with a common mean and unequal variances. Estimation of a quantile of the first population is considered with respect to the quadratic loss. Some new estimators for the quantile are proposed using some previously known estimators of a common mean. Inadmissibility results are proved for estimators which are equivariant under affine and location groups of transformations. Risk values of various estimators of a quantile are compared numerically using a detailed simulation study.     

Book Review: Introducing Monte Carlo Methods with R

In this article we propose a nonparametric test for poolability in large dimensional semiparametric panel data models with cross-section dependence based on the sieve estimation technique. To construct the test statistic, we only need to estimate the model under the alternative. We establish the asymptotic normal distributions of our test statistic under the null hypothesis of poolability and a sequence of local alternatives, and prove the consistency of our test. We also suggest a bootstrap method as an alternative way to obtain the critical values. A small set of Monte Carlo simulations indicate the test performs reasonably well in finite samples.     

McDonald's ωt,Cronbach's α, and Generalized θ for Composite Reliability of Common Factors Structures

In the common factor model for subtest scores, several reliability coefficients, including Cronbach's α, have been found to be biased. In this article, we introduce a new coefficient, θ_G, or Generalized θ, which is a generalized version of Armor's θ coefficient and is equal to the true reliability when the dimensions are orthogonal and the measures are parallel. We assessed the McDonald's ω_t, α, and θ_G in terms of mean bias, efficiency, and precision using a Monte Carlo simulation. θ_G outperformed ω_t when the factors were orthogonal or nearly orthogonal with low correlations between them.     

Testing hypotheses about the common mean of two normal populations

Two simple tests which allow for unequal sample sizes are considered for testing hypothesis for the common mean of two normal populations. The first test is an exact test of size a based on two available t-statistics based on single samples made exact through random allocation of α among the two available t-tests. The test statistic of the second test is a weighted average of two available t-statistics with random weights. It is shown that the first test is more efficient than the available two t-tests with respect to Bahadur asymptotic relative efficiency. It is also shown that the null distribution of the test statistic in the second test, which is similar to the one based on the normalized Graybill-Deal test statistic, converges to a standard normal distribution. Finally, we compare the small sample properties of these tests, those given in Zhou and Mat hew (1993), and some tests given in Cohen and Sackrowitz (1984) in a simulation study. In this study, we find that the second test performs better than the tests given in Zhou and Mathew (1993) and is comparable to the ones given in Cohen and Sackrowitz (1984) with respect to power..
