西方理性主义及其现代命运

西方文化在本质上是理性主义文化,即以“逻各斯”精神和“努斯”精神的对立为重要规定的文化,现代人本主义、科学主义和马克思主义思潮就是对这一文化及其矛盾的现代理论表征、反思和批判。现代人本主义批判传统理性主义的“逻各斯”精神,要求理性回归人的生活,以丰富的人性取代“冷酷的理性”;现代科学主义则批判传统理性的“努斯”精神,要求理性回归经验世界,以谦虚的理性取代“狂妄的理性”;马克思主义思潮从总体性的实践活动出发,对传统理性主义和资本主义制度进行了系统、深入的分析和批判。     

Household Assets,the Role of Government Assistance,and Depression Among Low-Income Families in Shanghai

As China’s economy is rapidly changing from a planned to a capitalist economy, many families find themselves financially struggling. In some cases, conflicting values and attitudes may contribute to mental health challenges such as depression that would lead to further feelings of helplessness and immobilization. Using a random sample of 1006 low-income households from Pudong District of Shanghai, China, this study aims to examine the relationships between household assets, beliefs about government as the primary way to improve economic circumstances and self-reported depressive symptoms. In addition, this study investigates the mediation effects of beliefs that government is the best change agent for improved life circumstances on the relationship between household assets and depression. We found those who indicated that government was the main means for attaining a better life had significantly higher depression levels whereas higher numbers of household assets were associated with lower depression levels. We also found that viewing government as the most important change agent only partially mediated the relationship between household assets and depression (p?<?.001). Findings from this study support anti-poverty policies and social work related practice initiatives aimed at assisting low income families in China, in particular the need to address psychological as well as economic needs.

     

可持续生计视角下"参与式"反贫困路径探索

中国扶贫实践中出现的"贫困户生计能力提升不足"倾向源于可持续生计框架与现代贫困观念之间的冲突,而"社会参与"则为解决冲突提供了一种可能。2020年后,面对新的贫困现象和贫困结构,"参与式"反贫困理念能够通过社会参与链接可持续生计框架和现代贫困观念,在贫困治理过程中充分体现贫困者的参与性,形成主体意识和责任意识,提升个体或家庭改善生计系统的能力,使其摆脱困境、规避陷入贫困的风险,进而形成权利-义务相平衡、对城市和农村具有包容性、常态化、可持续的贫困治理策略,使全体社会成员实现不虞匮乏的生活。     

中日关系史与经济史研究领域的新探——《日本工商资本与近代山东》评介

在不同的历史时空视野下,研究对象所具有的典型性及其意义,为我们认识和把握历史的基本特征提供了可能.近代山东是日本经济势力对华扩张的重要地区,其中若干历史过程、事件及问题在近代日本侵华史上具有一定的代表性和典型性.从这一意义上说,日本工商资本与近代山东的关系是近代中日关系史、经济史的重要组成部分.由于这种关系形成于殖民化与现代化的双重历史背景之下,是近代日本对华殖民经济扩张的产物,因而对于研究近代日本对华经济扩张、认识区域社会经济嬗变特点具有重要的学术意义和理论价值.     

欧洲一体化进程中的"反一体化"分析

随着欧洲一体化的演进,反对、抵制一体化的思想与行动一直此起彼伏,反一体化伴随着一体化进程的始终."反一体化"活动主要在国家、政党和民众三个层次上展开,遍及政治、经济、社会文化等领域.其动因主要在于一体化进程对利益的重新分配所引发的复杂利益冲突和传统主权观、民族主义思想与一体化现实之间产生的尖锐对立."反一体化"对一体化进程产生了重要的影响.一方面它是一体化前进的阻力,另一方面又对一体化的发展产生了建设性的影响,使一体化能够相对稳定地向前迈进.反一体化将长期存在,并在欧洲一体化的未来发展中继续发挥自身的作用.     

Variance estimation based on blocked 3×2 cross-validation in high-dimensional linear regression

In high-dimensional linear regression, the dimension of variables is always greater than the sample size. In this situation, the traditional variance estimation technique based on ordinary least squares constantly exhibits a high bias even under sparsity assumption. One of the major reasons is the high spurious correlation between unobserved realized noise and several predictors. To alleviate this problem, a refitted cross-validation (RCV) method has been proposed in the literature. However, for a complicated model, the RCV exhibits a lower probability that the selected model includes the true model in case of finite samples. This phenomenon may easily result in a large bias of variance estimation. Thus, a model selection method based on the ranks of the frequency of occurrences in six votes from a blocked 3×2 cross-validation is proposed in this study. The proposed method has a considerably larger probability of including the true model in practice than the RCV method. The variance estimation obtained using the model selected by the proposed method also shows a lower bias and a smaller variance. Furthermore, theoretical analysis proves the asymptotic normality property of the proposed variance estimation.     

Outlier detection and robust variable selection via the penalized weighted LAD-LASSO method

This paper studies the outlier detection and robust variable selection problem in the linear regression model. The penalized weighted least absolute deviation (PWLAD) regression estimation method and the adaptive least absolute shrinkage and selection operator (LASSO) are combined to simultaneously achieve outlier detection, and robust variable selection. An iterative algorithm is proposed to solve the proposed optimization problem. Monte Carlo studies are evaluated the finite-sample performance of the proposed methods. The results indicate that the finite sample performance of the proposed methods performs better than that of the existing methods when there are leverage points or outliers in the response variable or explanatory variables. Finally, we apply the proposed methodology to analyze two real datasets.
