基于结构方程模型的快递行业顾客满意度研究

采用结构方程模型对理论模型进行验证。研究结果显示,顾客消费期望对满意度的影响最大,且成负向关系。除直接影响外,其还通过快递企业服务流程和顾客价值感知间接影响顾客满意度。     

中国“一带一路”战略定位的三个问题

"一带一路"战略在大方向基本清晰的情况下,在战略定位上仍然存在着三个有待进一步厘清的问题,包括:"一带一路"是全球战略还是区域战略?"一带一路"应以多重双边伙伴关系为基础还是应以跨区域整合为基础?"一带一路"战略应以西北方向为优先还是应以东南方向为优先?对这三个问题的诠释对于"一带一路"战略的推进有着极为重要的意义。这一战略虽然表现出了一定的全球战略的特征,但在本质上还是区域性的;其的推进必须以多重双边伙伴关系为基础。就目前的具体政治形势与经济形势来看,"一带一路"战略开拓西北面临更大的不确定性。     

基于粒子群算法下的交叉口信号配时优化

为了合理地优化交叉口信号配时,通过分析交叉口的评价指标,建立了以车辆的平均延误、停车次数最小、交叉口整体通行能力最大、各相位有效绿灯时间和交叉口周期时长作为约束条件的数学模型。并通过改进前人研究基础上的动态加权系数,将多目标的非线性优化问题转化为单一目标的非线性规划问题,为了得出更科学稳定的解,提出了改善粒子群算法系统稳定性的2种方法,并将其与粒子群算法结合起来。然后以Matlab为求解工具,结合临邑市某一交叉口实例进行求解分析。最后的结果表明,在使用改进后的粒子群算法进行优化后交叉口通行能力较之现状提升了9%,延误下降了28%,停车次数下降了9%,且各项优化结果均优于Webster,改进后的算法在程序中运行300代,到216代才开始收敛,而未改进的算法稳定性较差,优化结果和收敛曲线则随着实验次数的变化而变化,最后的结论证明了该算法和模型的可靠性。

Effects of investor tax heterogeneity on stock prices and trading behaviour around the ex-dividend day: the case of Australia

Using a sample of Australian stocks during the 1996–2014 period, this study examines how tax heterogeneity between domestic and foreign investors affects trading behaviour and stock prices around the ex-dividend day. Domestic investors prefer dividends and tend to buy stocks cum-dividend and sell them ex-dividend whereas foreign investors tend to trade in the opposite direction. Abnormal trading turnover increases with tax heterogeneity. Moreover, stocks with a larger domestic investor base are associated with a higher price drop-off ratio on the ex-dividend day and higher market value of franking credits. Overall, our findings support the dynamic dividend clientele hypothesis.     

The Low‐Pay No‐Pay Cycle: Are There Systematic Differences across Demographic Groups?

We investigate transitions between unemployment, low‐paid employment and higher‐paid employment using dynamic panel data methods applied to household panel data. We find state dependence in both unemployment and low‐paid employment and evidence of a low‐pay no‐pay cycle. However, we also find significant differences in effects across population subgroups. Typically, the young and better‐educated face lower penalties from unemployment and low‐paid employment. Further, low‐paid employment is preferable to unemployment for women regardless of their demographic characteristics, but for men who have only completed secondary schooling, low‐paid employment actually decreases the chances of entering higher‐paid employment by more than does unemployment.     

The Prospect of Ethical Consulting

Ethical consulting is a critical professional activity that is very critical to the very survival of the corporate world and is thus likely to boom within the shortest possible time in the future. This predictive statement is based on the consequential effect of the bankruptcy of Ertron and WorldCom and its aftermath legislature, Sarbanes-Oxley Act （Lander, 2004）. The main issues boarder on how ethics influence organizations＇ operations and to what extend these influences can be coded and managed to enhance objectivity and minimize fraud. The methodology applied in this paper was an exploratory approach under the qualitative design. It encapsulates a thorough review of literature on the subject matter and draws inferences to address the research objectives. It was found that ethical consulting was possible and consultants venturing into the area need to be strategically diversified to enable them to design and develop customized ethical codes for the heterogeneous clientele with appropriate supporting monitoring and compliance procedures.     

耦合产业系统中资源与污染的结构性动态分析

可持续的产业发展分析往往关注于经济增长与资源、环境之间的互动影响,以及它们在最优增长路径上的动态分配过程,一般很少考虑产业依赖的资源与产业发展中环境诸要素(如衰减能力、环境本底值等)的背景条件不同而引发的耦合产业结构和规模的问题[1-14]。本文主要对基于资源消耗和可持续发展框架下耦合产业系统的最优化增长路径上产业结构的动态变化进行刻画和模拟实证。数值模拟显示,对于可持续的耦合产业系统长期发展而言,两个产业的结构和规模将随着环境诸要素动态变化,随之产生的社会效益和环境损害也是动态变化的。而且,资源的消耗水平、耦合产业中各子产业的发展结构、环境条件将影响到耦合产业系统的最优增长路径,在特定的情况下将出现类似于Kuznets曲线性状的拐点。
