重庆市经济结构调整的探索

通过对重庆市经济结构中存在的九个方面矛盾的分析 ,结合现代产业结构调整的理论 ,首先剖析了影响结构调整的体制因素和技术因素 ,从理性角度探求重庆市经济结构调整的方法和路径。再结合重庆市的实际情况 ,提出了在重庆市经济结构矛盾中 ,区位矛盾是主要矛盾 ,而城市化则是解决区位矛盾的主要途径。因此近期应该以城市化为龙头、以工业化为依托、以基础设施建设为先导 ,以扩大内需为根本出发点 ,以创新和开放为动力 ,推进重庆市经济结构调整     

后现代主义与网络文学

后现代主义与网络文学是近年来学术界关注较多的两大学术焦点，文章系统地论述了后现代主义思潮与网络文学的关系，并从去中心与自由、平面化与游戏、复制性与互文、消费性与狂欢四个方面分析了网络文学的后现代主义文化逻辑。     

论道德规范对社会经济发展的作用与影响

本文就道德规范对社会经济发展的作用与影响进行了多视角的剖析和论述，其中重点探讨了道德规范与社会经济制度的建设、与社会经济行为的校正、与社会经济关系的协调以及与经济体制的改革等的关系问题。     

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。

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.     

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.
