在大量文献研究的基础上,对收敛问题的产生及收敛概念的发展作了全面概括,并对绝对收敛、条件收敛、俱乐部收敛和σ收敛作了深入辨析,对各种识别方法作了全面归纳。归纳了对世界大多数国家和地区数据所作识别的结果。还从收敛理论与传统理论的冲突与协调方面作了深入分析。最后对近年收敛研究的深化与扩展研究的趋势作了概括。     

Inference for quantile measures of kurtosis,peakedness, and tail weight

Insight into measures of peakedness, heavy-tailedness, and kurtosis can be gained by studying Ruppert’s ratios of interquantile ranges. They are not only monotone in Horn’s measure of peakedness when applied to the central portion of the population, but also monotone in the practical tail-index of Morgenthaler and Tukey, when applied to the tails. Non-parametric confidence intervals are found for Ruppert’s ratios, and sample sizes required to obtain such intervals for a pre-specified relative width and level are provided. In addition, the empirical power of distribution-free tests for peakedness and bimodality are found for some symmetric distributions.     

动态性与静态性:教学目标的确定及实现——以“教育研究方法”课程为例

教学目标的存在有应然状态和实然状态之分。"教育研究方法"课程的静态目标应具体体现为"涵养科学精神、问题意识的形成、基本研究技能的掌握和有效获取文献信息",这些目标在实现过程中必然存在着动态性选择。

Semi-doubly optimal concentric circles fitting with presence of heteroscedasticity

Previous studies focus on homogeneous and isotropic assumptions about the noisy data. Many methods have been developed recently for fitting concentric circles to data. In this paper, these statistical assumptions have been relaxed. To the best of our knowledge, only one iterative method has been recently developed. Due to its complexity, no such algorithm is available to compute the reliable maximum likelihood estimator (MLE). Accordingly, we have developed four new methods that outperform the existing methods including the orthogonal distance regression (ODR). We also discuss which of these methods is superior according to the four principles: statistical efficiency, accuracy, robustness, and computational efficiency. Numerical experiments on synthetic and real images have been conducted to validate our findings.     

Relations Between Alphabetized Name Order and Nomination Counts in Peer Nomination Measures

Peer nominations, a central method for measuring peer relationships in developmental research, typically involve asking children or adolescents to choose peers who fit various criteria from an alphabetized roster of classmates or grade‐mates. Although such measures have been used for decades, very little research has investigated the effects of alphabetical name order on the number of nominations received by peers. This study collected peer nominations for 20 items among 607 eighth grade participants in two schools. Regression analyses showed that earlier name order significantly predicted higher nomination counts for eight of the items, and explained over 5 percent of the variance in four affective variables (friendship, acceptance, acquaintanceship, and received liking). Across variables, name order effects were negatively correlated with internal reliability of nominations, implying that order effects may be related to the consensus of the peer group. Name order also had a minimal effect on inter‐correlations among a subset of variables. Implications and concrete recommendations for controlling and reducing name order effects in future research are discussed.     

古籍整理中的辨伪例说

辨伪是古籍整理的重要工作。本文在总结历代学人关于辨伪理论及方法的基础上,以古籍整理实践中的九个典型实例,具体说明辨伪的方法：考证作者的生平事迹,审核作品的思想内容,检验作品的语言风格,查阅历代的相关书目,寻找各种有用的旁证等,以期尽可能恢复古籍原貌。     

Monte Carlo comparison of five exponentiality tests using different entropy estimates

The paper studies five entropy tests of exponentiality using five statistics based on different entropy estimates. Critical values for various sample sizes determined by means of Monte Carlo simulations are presented for each of the test statistics. By simulation, we compare the power of these five tests for various alternatives and sample sizes.     

苏雪林文学批评之比较方法的运用

在苏雪林的文学批评中，比较手法的运用是极为显著且常见的。中国古典文学深厚的积淀，西方文学文化的深刻熏陶，使其比较之法不仅仅涉及到同时期、同流派作家之间的平行比较，更有以古典文学为借鉴的古今比较，及以西方文学为参照的中西比较。这种多层次、多方面的比较，使中国现代文学在苏雪林的评论中处于一个广阔而又立体的环境中，这一方面突显了苏雪林的敏锐观察力，同时也折射出了中国现代文学在中西纵横交错中的独特魅力。     

“赔礼道歉”的异化与回归

我国《侵权责任法》延续了《民法通则》的规定,将赔礼道歉作为侵权责任承担方式之一种。从赔礼道歉责任承担方式在我国的产生来看,其有一定的历史时代原因;但在现代法的背景之下,该种责任承担方式不仅在理论上争议颇多,而且造成了司法实践中问题重重,其作为一种责任承担方式的合理性值得怀疑,将其从法律责任还原为道德责任实属必要。
