关于克尔凯郭尔在中国

关于克尔凯郭尔在中国的接受情形 ,刘小枫认为 :汉语知识人“对Kiekegaard一直陌生 ,未见过有哪位文化名人亲近过他” ,本人不同意这一认识 ,本文力图通过史实进行初步勘察 ,并以鲁迅、李石岑、冯至 (鲁迅为主兼及李石岑、冯至 )等文化名人为例证进行初步辨析     

坚持共同富裕 缩小贫富差距

流动人口自雇的决定机制及收入差异

除工资雇佣外,自雇(包含有雇工自雇和无雇工自雇)是流动人口重要的劳动参与方式. 本文基于2016全国流动人口调查数据,采用多项logit模型考察了自雇的决定机制,并从平均和非线性维度分别运用倾向得分匹配和无条件分位数处理效应模型测度了不同劳动参与方式之间的收入差异. 实证分析结果表明：1)教育有利于流动人口有雇工自雇而无助于无雇工自雇,男性较女性更容易产生自雇,户籍并不会明显影响自雇;专业技术人员并不倾向于自雇,而服务业中的非技能劳动力自雇可能性更大. 2)流动人口有雇工自雇的平均收入水平最高,其后依次为无雇工自雇和工资雇佣;经济越发达的地区,流动人口自雇与其他劳动参与形式的收入差异越大. 3)相对于工资雇佣,流动人口两类自雇的收入均随收入水平上升而递增,且有雇工自雇引致的收入差异更大;不同劳动参与方式间的收入差异主要源于个体间的条件(禀赋)差别.     

基于讨价还价能力的竞争供应链渠道结构绩效研究

本文就独立分销渠道的讨价还价理论在竞争供应链渠道结构面临的问题进行建模,对不同讨价还价能力和产品差异的竞争渠道结构的演化过程进行分析,发现产品与零售商讨价还价能力的差异对竞争渠道结构的选择具有重要影响,并给出了相应结构的演变过程和均衡结果的范围.拓展了Iyery的单渠道结构理论的结果,并为不同环境下渠道结构的选择提供了理论依据.     

行业投资者情绪的测量及其对收益的影响效应研究

投资者情绪对行业收益影响研究的关键在于行业情绪的测量。基于封闭式基金折价、交易量、波动率、行业beta值和每股流通市值这5个单项情绪指标提取主成分,构建了23个申万一级行业的投资者综合情绪指数(IICSI),并通过面板数据模型分析了各行业的投资者情绪对收益的影响效应。实证结果表明,投资者情绪对当期收益具有短期、中期和长期的正向激励作用,但对预期收益则只在短期和中期表现出正向效应,而在长期反转为负向的抑制效应,并且情绪对当期收益和预期收益的影响都具有显著的行业差异性,最后基于情绪对预期收益的行业影响差异构建了不同投资期限下的套利策略。     

Partitioned difference families and almost difference sets

Partitioned difference families (PDFs) were first studied by Ding and Yin in conjunction with the construction of constant composition codes (CCCs). In 2008, Yin et al. presented the constructions of a number of infinite classes of PDFs based on known difference sets in GF(q). In this paper, we further investigate the constructions of PDFs by using known almost difference sets in GF(q), and establish some recursive constructions of PDFs. As their applications, we also get a number of perfect difference systems of sets (DSSs) over Z_q² with q odd prime.     

Optimal caliper widths for propensity-score matching when estimating differences in means and differences in proportions in observational studies

In a study comparing the effects of two treatments, the propensity score is the probability of assignment to one treatment conditional on a subject's measured baseline covariates. Propensity-score matching is increasingly being used to estimate the effects of exposures using observational data. In the most common implementation of propensity-score matching, pairs of treated and untreated subjects are formed whose propensity scores differ by at most a pre-specified amount (the caliper width). There has been a little research into the optimal caliper width. We conducted an extensive series of Monte Carlo simulations to determine the optimal caliper width for estimating differences in means (for continuous outcomes) and risk differences (for binary outcomes). When estimating differences in means or risk differences, we recommend that researchers match on the logit of the propensity score using calipers of width equal to 0.2 of the standard deviation of the logit of the propensity score. When at least some of the covariates were continuous, then either this value, or one close to it, minimized the mean square error of the resultant estimated treatment effect. It also eliminated at least 98% of the bias in the crude estimator, and it resulted in confidence intervals with approximately the correct coverage rates. Furthermore, the empirical type I error rate was approximately correct. When all of the covariates were binary, then the choice of caliper width had a much smaller impact on the performance of estimation of risk differences and differences in means.     

《无声告白》族裔文化表征背后的沟通主题

新一代华裔美国作家武绮诗的小说《无声告白》,呈现了一系列二元对立的冲突与矛盾：亚裔与白人、女性与事业、父母期待与子女压力、子女的得宠与失宠等,表现出族裔与异质文化的显性特性。然而,细读文本可以发现,在上述表征的背后,作者通过沟通缺失导致悲剧的设置,突出了隐性的沟通主题。小说中的族裔差异和异质文化,只是承托作者价值观的一个载体,而现代人共通的沟通主题才是触动不同读者心灵的精神所在。这种超越族裔本质论的主题转型,反映了新一代华裔美国文学的新特征。     

基于奈达理论的文化转化策略和技巧
