制造商竞争下闭环供应链的押金返还制度研究

本文研究制造商竞争环境下,政府对闭环供应链成员实施押金返还制度时,废旧电器电子产品的回收决策问题。首先构建了制造商完全垄断情形的闭环供应链基准决策模型,然后考虑制造商之间的竞争,分别构建政府对制造商和对回收商实施押金返还制度的闭环供应链决策模型,最后对结果进行比较和分析。研究表明：押金返还制度可以使新产品的零售价和废旧产品的回购价降低;制造商间的竞争和押金返还制度均可以提高闭环供应链中废旧电器电子产品的回收率;与对制造商实施押金返还制度的情形相比,对回收商实施押金返还制度时闭环供应链的总利润和回收率更高。     

突发事件应急管理中公共财政应急机制探讨

本文通过对突发事件公共财政应对状况研究与实践的评述,结合国外公共财政应对突发事件的经验,分析我国公共财政应对过程中存在的问题,从宏观层面构建了我国公共财政的应急机制框架,最后借助云南大姚地震案例对公共财政应急框架进行了实证分析.     

Minimal Tetrahedralizations of a Class of Polyhedra

Given a simple polyhedron P in the three dimensional Euclidean space, different tetrahedralizations of P may contain different numbers of tetrahedra. The minimal tetrahedralization is a tetrahedralization with the minimum number of tetrahedra. In this paper, we present some properties of the graph of polyhedra. Then we identify a class of polyhedra and show that this kind of polyhedra can be minimally tetrahedralized in O(n ²) time.     

中国ESI学科建设研究的现状、问题及对策——基于2003—2017年核心期刊文献的计量分析

文章系统梳理了国内外ESI学科领域研究现状,通过对2003年1月至2017年6月CNKI核心期刊发表的“ESI学科”主题论文的计量分析,发现该领域研究存在若干问题:论文成果数量逐年增长但仍不多,论文来源期刊和机构分布不尽合理,作者专业结构有待优化、核心作者群体尚未形成,学科排名和一流学科建设是研究的热点,研究主题多为应用对策类,基础研究类成果极为缺乏.针对上述问题,笔者提出了具体的对策建议.     

论高校思想政治理论课实践教学的整合

"05方案"后,高校思想政治理论课实践教学取得了丰硕成果,但是四门思想政治理论课实践学时的分散性,导致实践教学在具体操作中存在诸多困难。为充分发挥实践教学的功效,应当对四门思想政治理论课的实践教学进行总体整合与具体设计。整合后的实践教学,实现了教学过程的优化,体现了现代教学理念,有利于采用现代教育技术。     

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     

Is Tattooing a Risk Factor for Adolescents’ Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes.     

地方戏剧中的前景化语言英译——以商洛花鼓戏《月亮光光》为例

随着“一带一路”战略规划的提出,地方文化受到了翻译界的关注.地方戏剧中的前景化语言却成了使之走出国门的拦路虎.本研究以商洛花鼓戏《月亮光光》中的前景化语言为切入点,分别从质量凸显和数量凸显两个方面探讨并提出花鼓戏的翻译原则,采用对等替换、移植、转换、舍弃等技巧试译,旨在为地方戏剧的翻译提供切入点,产生兼具文学性和表演性的花鼓戏英译本.
