Does delaying service-failure resolution ever make sense?

Conventional wisdom suggests that service providers should respond to their failures as quickly as possible. Some research, however, points out that delaying resolutions may produce highly desirable results. The study here investigates these competing views by examining under which conditions an immediate or a delaying resolution produces more positive consumer responses in term of re-patronage and negative word-of-mouth intentions. Based on the concept of service separation, this research identifies an interaction effect between service separation (separated service, non-separated service) and response timing (immediate response, delaying response) on consumers' post-consumption intention. This research also finds that the relationship between service separation-response timing interaction and consumer response is mediated by consumers' negative emotions. This study contributes to refining our understanding of consumer psychology in service recovery. Practically, the studies also enable service providers to better allocate their resources to recover different types of services' failure.     

权利冲突：逻辑与现实

权利冲突问题是近年来法理学和民法学研究的一个热点问题,也是包括宪法学在内的许多法学学科领域的一个重要课题。笔者认为,在权利冲突问题的研究中,无论是权利冲突的界定,还是权利冲突的形式,无论是权利冲突的原因,还是权利冲突的化解,都既不能没有逻辑视野的开拓,更不能没有现实世界的观照。     

论区域金融风险的防范与化解

区域金融风险作为一种客观经济现象,其产生既有金融业自身的原因,也有金融业之外的原因。应该从建立区域金融风险预警系统、建立和完善金融机构内部风险控制体系、改进区域内金融监管机构对区域金融风险的监控水平、强化区域内金融机构的行业自律、改善防范与化解区域金融风险的外部环境等方面入手,对区域金融风险进行有效的防范与化解。

应用于雷达方位超分辨的改进Richardson-Lucy算法

方位超分辨是国内外雷达界持续探索的一项技术难题。为解决高斯噪声情况下天线低通效应造成的方位低分辨力问题,利用基于泊松噪声情况下Richardson-Lucy(RL)算法对其进行研究。针对RL算法中高斯噪声被放大出现虚假目标和RL算法收敛速度慢的缺点,提出了一种改进RL算法。该算法首先使用低通滤波去除高频段的噪声,然后利用加速RL算法进行方位超分辨。仿真结果表明：与原RL算法相比,改进RL算法能降低高斯噪声的影响,消除虚假目标;在信噪比低至0 dB时,相对于半功率波束宽度,改进RL算法的最大分辩倍数为1.8倍,与维纳逆滤波算法相比具有较强的噪声适应能力,可以应用于雷达方位超分辨。     

基于联合概率加权的高分辨雷达目标点迹处理

针对高分辨雷达在跟踪扩展目标时出现多散射点的问题,提出了一种基于联合概率加权的雷达目标点迹处理方法。首先,对信号检测出的多散射点构建其残差变量,根据判别准则进行目标点迹配对处理,剔除异常散射点;然后,同时考虑散射点位置和回波幅度信息,计算联合概率的权值,目标多散射点经概率加权融合后估计得到散射中心。仿真分析表明,该方法在高分辨雷达扩展目标点迹处理中能有效抑制杂波的干扰,目标点迹精度在距离、方位和俯仰上分别提高了20.63%、47.51%和41.03%,同时具有很好的可靠性,满足工程应用的需求。     

Public participation and local environmental planning: Testing factors influencing decision quality and implementation in four case studies from Germany

Public and stakeholder participation in environmental planning is often assumed to enhance effectiveness through improving the environmental quality of decisions and enhancing implementation. We draw on the literature on participatory environmental governance in order to derive key participation-related factors that are hypothesized to impact on decision quality and implementation. We then outline four cases of decision-making processes in local environmental planning in Germany, representing a variety of forms of public participation, and what we suggest can be seen as four different pathways to ‘success’ in participatory planning. The case studies, recounted on the basis of stakeholder interviews and secondary research, are subjected to a cross-case analysis in order to examine the influence of participation in each case. We consider how key participation-related factors played out across the cases, and assess both decision quality and implementation against counterfactual non-participatory, or less-participatory, scenarios. In moving beyond accounts of ‘what happened’, and considering how participation changed the order of things relative to ‘what would have happened’ under different scenarios, the research highlights how very different pathways may lead to ‘success’ in participatory environmental planning from the viewpoint of process organizers and planners sympathetic to environmental issues. We conclude that, given the significance of context and surprises, planners and process organizers must be open to different pathways to the successful conclusion of participatory planning processes.     

WTO体制下非贸易价值理念的研究

WTO创建以来,不仅延续了GATT不断推进的自由贸易理念,更在体制上不断创新.其中表现为WTO规则中非贸易价值理念的扩张.而扩张的途径主要是通过争端解决机制的司法能动性而实现的.作为一个贸易合作组织,争端解决机制的司法能动性将WTO的管辖领域扩充至人权、环保等非贸易价值领域,损害了各成员方在WTO现行规则中达成的利益平衡,欠缺正当性和民主性.
