中国股票市场发展对货币政策冲击效应的实证检验

本文利用协整分析方法,对中国1992~2004年股票市场发展对M1、M2货币供给量变化的影响进行了实证分析与检验,发现以股票市值代表的股票市场发展对M1、M2有着明显的吸收效应;并提出了货币政策应该对股票市场发展对货币量的吸收情况予以关注,货币政策目标应该由维持一般物价水平的稳定转向维持广义物价水平的稳定。

航空客运合同成立时间——达成合意的回归

《合同法》以交付客票作为判断客运合同成立时间的基本标准,并不适合航空客运合同。设定航空客运合同成立时间,应考虑当事人间的利害平衡、法律原理、法律逻辑以及交易习惯等因素。航空客运合同不宜被规定为实践性合同。实践性合同通常要求一方在合意之外作出特定给付,目的在于给作出特定给付的一方（而非双方）深思熟虑的机会。航空客运合同中的支付票款、交付客票和换登机牌不符合实践性合同的适用场景,也没有适用必要。航空客运合同不宜被规定或约定为要式合同,除非航空客运合同不存在格式条款。要式合同本身对当事人造成一定的约束,会剥夺旅客另外通过口头交流与承运人做特殊约定的可能。航班信息的展示应被认定为要约邀请,旅客决定买票的表示是要约,承运人确定售票的表示是承诺。     

设施失灵风险下不确定需求应急定位-路径鲁棒优化研究

为抵御突发灾害对路网造成的破坏性和设施失灵风险,降低系统成本,并快速完成应急救援任务,本文考虑到受灾点物资需求量的不确定和风险对救援系统的影响,采用直升机进行物资运送以规避路径风险。建立了最小化应急物流系统总成本和物资到达需求点总救援时间为双目标的应急物流定位-路径鲁棒优化模型,基于相对鲁棒优化方法处理需求不确定,采用偏差鲁棒优化思想描述设施失灵风险损失,采用遗传算法进行求解。通过对三个算例进行数据仿真实验,证明了相对鲁棒优化方法在处理需求不确定和偏差鲁棒优化方法在处理设施失灵风险方面的有效性,进而为解决应急设施点的开设和救援物资的安全及时准确配送,增强应急物流系统的风险应对能力提供了有效的方法。     

On the impact of collaborative strategies for goods delivery in city logistics

Abstract

City logistics refers to the process of total optimisation of the logistics and transport activities in urban areas while considering economic, environmental, social and safety aspects. This paper considers a collaborative scenario for the urban goods transport planning and management as a way to reduce transport costs, congestion and environmental impact of this activity. An approach from the Operations Management field, using mathematical modelling, for tactical and operational decision-making is proposed to discuss and compare both collaborative and non-collaborative scenarios. This approach is validated using real data taken from the city of Bogotá, Colombia. Results put in evidence the quantitative benefits that can be achieved when collaborative logistics operations are implemented, represented in both transportation costs and environmental impacts. Although these results might not be surprising (like in the field of supply chain management), the contribution of this paper is centred in the fact that the impacts of collaboration in city logistics have not yet been quantified until now. This allows an ‘ex ante’ evaluation of the benefits of collaborative goods transport in cities.     

Performance Management,Caseloads and the Frontline Provision of Social Services

Caseloads and performance management are important working conditions of workers delivering public social services in street‐level organizations. The literature on these working conditions argues that high caseloads and performance management have considerable consequences for workers' performance in terms of the quality of services they provide and the results they realize. This article empirically investigates and compares these consequences, drawing on the results of a quantitative study of frontline workers in 14 local welfare agencies in the Netherlands. These workers are responsible for the delivery of welfare‐to‐work policies to social assistance recipients. The findings show that high caseloads do, indeed, have a detrimental effect on workers' performance, whereas the impact of performance management is more modest, though confirming some of the findings reported in other studies on performance management. The results also show that by focusing service provision on a proportion of their caseload, workers are able to reduce the negative impact of high caseloads somewhat. Overall, the article finds that the negative impact of high caseloads is more pervasive than that of performance management. The article concludes that the recent focus in the literature on performance management and its consequences for public services should not turn scholars' attention away from the ‘traditional’ public administration problem of high caseload sizes.     

竣工验收的多维分析

竣工验收是人们非常熟悉但又非常难以深入研究的课题，具有独立的学理价值，非常有学术深析的必要。它既是建筑技术行为，又是法律和经济行为，也是区分房地产和建筑工程的重要标志。不仅仅是竣工之后经验收达到合格状态，而且具有独立的经济价值。房地产发挥经济功能具有经济有效性，原因在于技术、经济和法律上完成“竣工验收”并达到合格状态。据此，竣工验收渗透于房地产和建筑工程运行全过程彰显特有效用，需要构成分析、法学分析、经济分析、权益分析和行政控制分析以及衔接关系共同剖析其学理真谛。

A Glimpse Within: An Exploratory Study of Child Welfare Agencies’ Practices With LGBTQ Youth

This article presents findings from a national survey of agency members of the Child Welfare League of America (CWLA) with respect to organizational culture and service delivery for lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth. Sixty-seven study participants provided quantitative and qualitative data via an Internet questionnaire. Overall, agencies fall short of fully subscribing to recommendations made by the CWLA. They could improve their support for providing an inclusive environment, creating supportive policies, and selecting childcare providers regardless of sexual orientation/gender identity. In addition, agencies varied with respect to the relative emphasis that services geared specifically for LGBTQ should occur. Although some progress has been made, much work remains for child welfare agencies to fully address the needs of LGBTQ youth.
