孔子的学习思想综述

孔子首先是一个好学者,一个成功的学习者,而后才是一个成功的教育者。孔子的学习思想可以用“好学”来概括。孔子“好学”的精义在“求道”。孔子是渊博的学者、仁爱的教者和真诚的长者,是伟大的老师,善于将知识转化为魅力,善于引导人通过学习知识健康地成长。     

Hard thresholding regression

In this paper, we propose the hard thresholding regression (HTR) for estimating high‐dimensional sparse linear regression models. HTR uses a two‐stage convex algorithm to approximate the ?₀‐penalized regression: The first stage calculates a coarse initial estimator, and the second stage identifies the oracle estimator by borrowing information from the first one. Theoretically, the HTR estimator achieves the strong oracle property over a wide range of regularization parameters. Numerical examples and a real data example lend further support to our proposed methodology.     

网络社区发现算法在流动表建模中的设计与应用

代际流动表可以统计子代与其父代社会地位配对数据的交互频数,反映了社会资源占有的优劣势在父子两代人之间的比较。对财富、阶级、特权等社会基本特征演变的实证考察,均依赖于代际流动表的量化分析。对数线性模型是流动表建模分析的基本工具,通过对列联表单元格频数进行拟合,可以识别流动表行分类与列分类之间的强弱交互效应,刻画父子社会地位间的交互结构。本文利用复杂网络社区发现算法分析父子社会地位的关联结构,针对简约对数线性模型拟合精度不够的问题,提出一种新的建模思路：利用社区发现算法对简约对数线性模型的残差列联表进行关联关系挖掘,将发现的社区效应作为附加参数约束引入原对数线性模型,以改善数据的拟合情况。由于该方法只在原简约对数线性模型中增加了一个参数约束,因此仍可以保证建模结果的简洁性及理论意义,同时社区效应补充了原对数线性模型对经验数据结构的解读。论文用此方法对来源于中国综合社会调查数据的经验代际职业流动表进行建模分析,较好地解释了子代职业阶层与父代职业阶层间的关联模式。     

高维大数据基因网络中的社区发现——以NC方法为例

从大量基因中识别出致病基因是大数据下的一个十分重要的高维统计问题。基因间网络结构的存在使得对于致病基因的识别已从单个基因识别扩展到基因模块识别。从基因网络中挖掘出基因模块就是所谓的社区发现（或节点聚类）问题。绝大多数社区发现方法仅利用网络结构信息,而忽略节点本身的信息。Newman和Clauset于2016年提出了一个将二者有机结合的基于统计推断的社区发现方法（简称为NC方法）。本文以NC方法为案例,介绍统计方法在实际基因网络中的应用和取得的成果,并从统计学角度提出了改进措施。通过对NC方法的分析可以看出对于以基因网络为代表的非结构化数据,统计思想和原理在数据分析中仍然处于核心地位。而相应的统计方法则需要针对数据的特点及关心的问题进行相应的调整和优化。     

REAL EXCHANGE RATE,MONETARY POLICY,AND THE U.S. ECONOMY: EVIDENCE FROM A FAVAR MODEL

This paper examines the effects of exchange rate depreciation to the U.S. economy in a factor‐augmented vector autoregression model using monthly data of 148 variables for the post–Bretton Woods period of 1973–2017. Exchange rate shock is identified to reflect exogenous disturbances to the foreign exchange market, and movements in exchange rate that are not accounted for by changes in the U.S. monetary policy. We find that depreciation is expansionary and inflationary to the broad U.S. economy, the current account improves over time conforming to the J‐curve theory, and monetary policy is leaning against the wind.

A phenomenological case study on immigrant workers' gambling addiction in Korea

This study explores the experiences that have led some of Korea's immigrant workers into gambling addiction and examines possible social welfare services that could support treatment. Immigrant workers' gambling experience as aliens in Korea was analyzed through the methodology of a phenomenological case study. The participants, who voluntarily consented to the study, were five immigrant workers addicted to gambling. Data were collected through one‐on‐one, in‐depth interviews over 6 months, starting in July 2018. The essential themes that emerged in the interviews were “changing strategies for survival,” “forgetting oneself without any sense of responsibility or shame,” “gambling as routine daily life,” “obsession with making a fortune in one go,” and “no home to return to.” Based on its results, this study makes suggestions for the prevention of gambling addiction in immigrant workers. Further, future research needs to be broadened to analyze nationwide cases of immigrant workers with more diverse demographic backgrounds.     

论真德秀《诗经》评点的政教观

真德秀《诗经》评点的政教观以教化为旨归,强调心性涵养、“性情之正”是实现外在政教的唯一途径和手段,把文学价值取向引向主体心性修养,将审美触须深深地扎向人的心性道德,赋予了《诗经》以道德的规定性,这种政教观对后世文学产生了影响。     

论司法中的程序公正

司法公正包括实体公正和程序公正两个方面,其中程序公正是司法公正的核心。罗尔斯将程序正义区分为纯粹的程序正义、完善的程序正义和不完善的程序正义三种类型。根据罗尔斯的程序正义理论,程序公正可以被视为纯粹的程序正义。程序公正的衡量标准包括法官中立、当事人平等、程序公开、司法效率这四方面的基本原则。     

创业团队异质性如何影响绩效:基于团队氛围中介效应的分析

从团队氛围的视角揭示为何异质性的创业团队更具优势,成功率更大,异质性的团队成员因为优势互补而直接提升创业绩效,此外创业团队异质性还通过团队氛围间接影响创业绩效。团队氛围对于帮助创业企业化解由于成员异质性所引起的矛盾和误解进而提升绩效具有重要作用,团队氛围在创业团队异质性影响绩效的关系中发挥部分中介作用。     

明代诗论中的易学命题--“富有”、“日新”的理学诠释与诗学影响

《周易?系辞》所说的“富有之谓大业,日新之谓盛德”是一个被不断赋予新内涵的理论命题。张载、朱熹的阐释表现出不同的思维方式和思想观念,渗透到文学领域,成为明代文学复古派诗论的重要理论支柱。何景明和王世贞多承张载之说,强调“义理一贯”以简化法度,李梦阳和李攀龙则多沿朱熹之论,看重“藏用”和“显仁”的辩证关系,坚信“变化”、“日新”是循序渐进的必然结果。
