Indirect membership function assignment based on ordinal regression

In many fuzzy sets applications, fuzzy membership functions are commonly developed based on empirical or expert knowledge. The equation of a membership function is usually determined somewhat arbitrarily. This paper explores a novel membership function design method based on ordinal regression analysis. The estimated thresholds between ordinal measurement categories are applied to calculate the intersection points between fuzzy sets. These intersection points are further applied to determine the equations of the membership functions. Information distortion due to empirical guess can thus be reduced and more latent information in the fuzzy responses can therefore be captured. A case study investigating the relationship between foster mothers’ satisfaction and the foster time and information provided has been conducted in this research. The applicability and effectiveness of the proposed membership function assignment approach have been demonstrated through several case studies.     

A Proportional Hazards Regression Model for the Subdistribution with Covariates‐adjusted Censoring Weight for Competing Risks Data

With competing risks data, one often needs to assess the treatment and covariate effects on the cumulative incidence function. Fine and Gray proposed a proportional hazards regression model for the subdistribution of a competing risk with the assumption that the censoring distribution and the covariates are independent. Covariate‐dependent censoring sometimes occurs in medical studies. In this paper, we study the proportional hazards regression model for the subdistribution of a competing risk with proper adjustments for covariate‐dependent censoring. We consider a covariate‐adjusted weight function by fitting the Cox model for the censoring distribution and using the predictive probability for each individual. Our simulation study shows that the covariate‐adjusted weight estimator is basically unbiased when the censoring time depends on the covariates, and the covariate‐adjusted weight approach works well for the variance estimator as well. We illustrate our methods with bone marrow transplant data from the Center for International Blood and Marrow Transplant Research. Here, cancer relapse and death in complete remission are two competing risks.

中国工业要素替代弹性的分解——基于直接替代效应和诱致性技术创新效应的研究

基于固定替代弹性(CES)生产函数构建了要素替代弹性分解的理论框架模型,根据技术进步是否发生改变,将要素替代弹性分解为直接替代效应和诱致性技术创新效应,并利用1978—2013年中国工业数据对其进行了实证检验分析。实证结果表明:在中国工业化进程中,中国工业资本与劳动之间是呈互补关系;同时,在要素替代过程中,诱致性技术创新效应起到了主要作用。因此,在中国经济转型的新常态下,应该继续加大技术创新的投入力度,加速推进工业产业技术升级,优化产业结构。     

新时代社会主义意识形态的功能提升研究

意识形态功能是意识形态基础研究的核心问题,从意识形态功能提升视角切入是推进我国社会主义意识形态建设的新视阈。在意识形态功能的研究中,抛开时代背景和具体实践谈功能,极易出现意识形态功能研究的“虚化”,形成对意识形态功能的空洞认识。在新时代的历史方位下,结合习近平新时代中国特色社会主义思想论证社会主义意识形态在政治、经济、文化、社会和外交领域的相关功能,以期在市场化、“微时代”、全球化的大环境下通过引领社会主义市场经济改革方向、净化网络空间以及争夺国际话语权等途径,真正实现社会主义意识形态功能的全面提升。     

A new heavy-tailed distribution defined on the bounded interval: the logit slash distribution and its application

This paper proposes a new heavy-tailed and alternative slash type distribution on a bounded interval via a relation of a slash random variable with respect to the standard logistic function to model the real data set with skewed and high kurtosis which includes the outlier observation. Some basic statistical properties of the newly defined distribution are studied. We derive the maximum likelihood, least-square, and weighted least-square estimations of its parameters. We assess the performance of the estimators of these estimation methods by the simulation study. Moreover, an application to real data demonstrates that the proposed distribution can provide a better fit than well-known bounded distributions in the literature when the skewed data set with high kurtosis contains the outlier observations.
