双线自闭区段客货列车速度比对扣除系数的影响分析

目前扣除系数的计算方法主要为分析法与模拟法，扣除系数的常见影响因素有客货列车速度比、区段均衡度、追踪间隔时分等。通过模拟法进行不同客货列车速度比下的运行图铺画，得出客货列车速度比对扣除系数的影响规律分析。实验表明：随着客货速度比的增加，扣除系数将逐渐变大，据此建议在相关双线客货混跑区段，选取合适的客货速度比，以减小对运行图通过能力的影响

论《古韵标准》中的方音假借现象

《诗经》中不再押韵的韵脚字,江永把它们归结为方言的不同读音。在《古韵标准》中,江永屡次提到"方音假借"、"方音偶借"的概念,以此为对象,可以研究其与后来段玉裁提出的"合韵"的关系。     

工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.     

比较优势动态递减概率模型及检验

在比较优势的持续时间是随机变量的条件下,文章运用不确定性数学方法和规范方法,推出了比较优势递减定理,认为比较优势会随着时间增加而递减,具有发散效应,即比较优势不会被锁定.推出的比较优势“无记忆性”定理表明,各国遵循比较优势发展国际贸易是正确的,国际贸易会让各个国家自动寻找到适合本国的比较优势.通过定义比较优势逆转概率,运用实证方法进行研究,研究表明比较优势基本符合比较优势递减定理和“无记忆性”定理内容,认为中国传统劳动密集型优势在逐渐减小,产业结构调整非常成功,逐渐拥有资本密集型优势和技术密集型优势,产业结构越来越合理.     

Overcoming Uncertainty: Agency,Stance, and the Rise of Collective Action in Times of Crisis

This article examines how grassroots actors initiate and engage in collective action to transcend dramatic situations of large-scale societal crisis. Merging strands of sociolinguistic scholarship with social movement theory, the concepts of stance and stance-taking are presented to reveal how individuals collectively exert their agency during episodes of macrostructural instability and uncertainty. Stance is defined as the agentive and solidaristic position taken up by a group of actors to navigate and overcome moments of social rupture. Stance-taking is the situational ensemble of discursive, organizational, and dramaturgical practice through which stances are developed and deployed. Analysis of the social construction of stance promotes multidimensional understandings of how social movements intensify and expand under conditions of crisis. To illustrate the analytical purchase of these concepts, the study describes the stance-taking practices that fueled the rise of mass public protests in Buenos Aires, Argentina, at the height of a national crisis in 2001.     

Dimension reduction via local rank regression

Outer product of gradients (OPG) achieves dimension reduction via estimating the gradients of the regression function. In this paper, we propose two novel OPG estimators via local rank regression: the rank OPG estimator and the Walsh-average OPG estimator. Both proposals guard against a wide range of error distributions, and are safe alternatives to existing OPG estimators based on local linear regression or local L1 regression. The effectiveness of the new proposals are demonstrated via extensive numerical studies.     

营业转让问题探讨

为了对我国营业转让的实践和立法有所帮助,文章运用比较分析的方法,对营业概念、营业转让的界定、营业转让中职工权益的保护以及营业转让平台的完善等问题进行了探讨.研究表明,由于我国法律未对营业转让进行明确规定,以致营业转让活动中存在着许多不规范、不合法的因素,阻碍了营业转让的顺利实现.指出我国立法机关应该借鉴国外法律,尽快制定全面、明确的营业转让制度,来规范、引导日益频繁的营业转让活动.
