工伤保险赔偿责任研究 ——以劳务派遣用工为切入点

劳务派遣作为一种灵活的用工形式,受到我国各类用人单位的青睐和广泛运用。2013年《劳动合同法》修订弥补了我国劳务派遣制度上的不足,但由于起步时间较晚,加上制度的复杂性,存在工伤赔偿制度的责任划分不清晰、工伤保险待遇先行支付具体操作存在困难、异地劳务派遣工伤保险制度执行不明确等方面的问题。我国需要从确立《劳动合同法》中派遣单位与用工单位的具体责任分担制度、完善劳务派遣工伤待遇先行支付规定、明确异地保险制度相关规定等方面入手,进一步完善工伤保险制度在劳务派遣用工中的适用,有效保护被派遣劳动者的合法权益。     

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.     

解读"整合"与"民族整合"

"整合"和"民族整合"两词在当前的学术论著中出现频繁,学者们对"民族整合"的理解也各不相同.实现学术话语的趋同性认识和使用,有利于消除歧异性理解,形成认知上的共识.本文在对"民族整合"的不同表述进行梳理的基础上,提出了自己的主张,并认为"民族整合"是不同于民族融合和民族同化的功能和过程.

农业税改革后我国农村公共产品供给问题及对策分析

农村公共产品的供给不仅影响着农村社会的正常发展,而且影响着我国全面建设小康社会的任务和目标的顺利实现。农业税改革在确保为农民减负增收的同时,也势必会对乡镇基层政府公共产品的供给能力造成影响。要打破城乡“二元结构”,加快农村经济发展;加大中央政府对农村公共产品供给的转移支付;改变乡镇基层政权对农村公共产品“自上而下”的供给模式,充分尊重广大农民意愿;拓展农村公共产品投资渠道;加强对农村公共产品的供给的监督;推进农民自主创业,努力促进农民增收。     

浅论我国公众参与城市规划的机制与措施

体现以人为本、维护社会公平和追求社会民主是公众参与规划的实质。发达资本主义国家在 2 0世纪60年代开始形成公众参与城市规划制度 ,而我国的城市规划决策承袭了计划经济体制下政府包揽社会生活所有方面的传统管理模式 ,急需以法律的方式指导公众参与 ,并大力推进新式社区的建设 ,以求形成公众参与的切实有效的机制     

从概念厘定到理论运用:西方民族冲突研究述评

此起彼伏、经久不息的民族冲突引发了国内外学术界的高度关注。自20世纪后半期,尤其是90年代以来,西方关于民族冲突的研究取得了快速发展。内容涉及界定概念、扩展范畴、探究原因、寻找规律和思考对策,尤其是在理论运用方面,致力于实现民族机制、冲突机制和国际关系机制的内在统一,为更好地理解民族冲突,探求解决民族冲突的理路提供了启示。     

大庆文化形态之分析

大庆市是一个多民族地区,其文化主要有三种形态:一是土著文化,即草原文化;二是移民文化,即农耕文化;三是工业文化,即近现代文化.在和谐社会建设中,大庆市在发挥工业文化主导作用的同时,要重视农耕文化,尤其要研究和重视草原文化的民族特性,从蒙古族所处的地理环境、资源条件、历史文化、民族特点等实际出发,依托和借助于地域的和民族的载体与形式,使草原文化不仅在传承中发展,也能在与农耕文化、工业文化的交融中更新.
