能动司法语境下的刑事审判模式

刑事审判模式在根本上属于开事司法问题,故能动司法必然牵扯刑事审判模式.从能动司法的内涵和特征出发,体现能动司法的刑事审判模式应是回应型刑事审判模式.回应型刑事审判模式包含着回应什么和如何回应即实体和程序两个层面,它包含并超越了适应性刑事司法与恢复性刑事司法.合情合理合法是回应型刑事审判模式的底线,或是其应遵守的基本原则.     

论上世纪90年代以来官场小说的叙事价值

上世纪90年代以来得到兴盛发展的官场小说,其存在价值在文学批评界一直评价不一。本文从理论界与作家自身对官场小说的不同评价入手,分析官场小说作家自身的认同感与社会的认同感存在差距的原因,强调官场小说的价值在于它的现实性和启蒙性。     

公共政策硇公共性——基于医疗改革视角的探析

医疗改革是党和政府重点强调的主要工作之一。医疗改革不仅关系到社会大众切身的根本利益,同时医疗改革的失败与公共政策的公共性有着密切的联系。因此,从医疗改革的角度理性地探讨和审视公共政策的公共性,并对当前公共政策公共性流失风险进行反思,认真探索其规避路径是具有重大意义的。     

基于灰色系统理论的民族地区基层人才发展策略研究

城乡差距的日益扩大,已极大地影响到民族地区的经济发展和社会稳定。解决这一问题的核心在于农民增收,而农民增收的关键又在于基层人才资源的开发。本文在对凉山州实地调研的基础上,利用灰色系统理论分析了当前民族地区基层人才的现状,提出了相应的解决问题的措施。     

发展“藏羌文化产业”的理路与策略

中国的文化发展和文化产业,正遭遇现代西方文化+中国传统文化+红色革命文化的"三重门"困惑。灾后重建,千方百计,抢救、恢复、保护和发展藏羌文化,乃其关键一端;而以发展文化产业来推动抢救、恢复、保护和发展藏羌文化,乃其关键一处。可以依循"文化差异-文化产业特色-市场区隔定位"的理路推进文化产品的开发。藏羌文化滋养于岷江,古蜀文化源于岷江,发展藏羌文化与产业,自然该抓住"岷江文化",不仅有利于保护母亲河岷江,而且也是阿坝州发展藏羌文化产业的一个战略切入点。发展藏羌文化产业,需要把藏文化元素、羌文化元素和藏羌文化元素同时代元素也就是市场需求结合起来。     

Variable selection and estimation for high-dimensional spatial autoregressive models

Spatial regression models are important tools for many scientific disciplines including economics, business, and social science. In this article, we investigate postmodel selection estimators that apply least squares estimation to the model selected by penalized estimation in high-dimensional regression models with spatial autoregressive errors. We show that by separating the model selection and estimation process, the postmodel selection estimator performs at least as well as the simultaneous variable selection and estimation method in terms of the rate of convergence. Moreover, under perfect model selection, the ℓ₂ rate of convergence is the oracle rate of $\sqrt{s/n}$, compared with the convergence rate of $\text{◂√▸}\sqrt{s\log p/n}$ in the general case. Here, n is the sample size and p, s are the model dimension and number of significant covariates, respectively. We further provide the convergence rate of the estimation error in the form of $\sup$ norm, and ideally the rate can reach as fast as $\text{◂√▸}\sqrt{\log s/n}$.     

出口产品质量与技能溢价：理论机制及中国证据

本文基于出口产品“质”的视角，理论阐释并实证检验出口产品质量对技能溢价的影响及其作用机制。研究发现：出口产品质量提高显著提升了劳动力技能溢价，这种提升效应在高技术行业更为明显；出口产品质量升级主要通过增加对高技能劳动力相对需求、改善企业利润和绩效等机制提升技能溢价，但出口产品质量影响技能溢价的产品价格机制未得到验证；技能溢价与高技能劳动力供给之间呈倒“U”型关系。因此，为防止出口产品质量升级加剧技能工资不平等，需要采取加强人力资本投资、增加高素质劳动力供给、完善与高质量外贸发展相适应的相对公平的收入分配政策等措施。     

A regularized variable selection procedure in additive hazards model with stratified case-cohort design

Case-cohort designs are commonly used in large epidemiological studies to reduce the cost associated with covariate measurement. In many such studies the number of covariates is very large. An efficient variable selection method is needed for case-cohort studies where the covariates are only observed in a subset of the sample. Current literature on this topic has been focused on the proportional hazards model. However, in many studies the additive hazards model is preferred over the proportional hazards model either because the proportional hazards assumption is violated or the additive hazards model provides more relevent information to the research question. Motivated by one such study, the Atherosclerosis Risk in Communities (ARIC) study, we investigate the properties of a regularized variable selection procedure in stratified case-cohort design under an additive hazards model with a diverging number of parameters. We establish the consistency and asymptotic normality of the penalized estimator and prove its oracle property. Simulation studies are conducted to assess the finite sample performance of the proposed method with a modified cross-validation tuning parameter selection methods. We apply the variable selection procedure to the ARIC study to demonstrate its practical use.
