Sybase数据库的磁盘镜像及故障恢复机制

数据库的可靠性是权衡数据库系统安全性的重要指标 ,数据库容错技术和有关故障 (包括系统故障、存储介质故障 )恢复决定了信息系统设计的规模和性能 ,特别是随着系统大型化 ,对数据库系统的联机处理性能提出了较高的要求 ,在故障恢复期间仍需具备一定的在线恢复 ( Non-Stop Recovery)能力。本文从故障恢复、磁盘镜像等方面讨论了Sybase数据库的有关机制     

Generating Enhanced Fishery Rents by Internalizing Product Quality Characteristics

This paper demonstrates howadditional rents are generated in a fisherycharacterized by intraseasonal variation infish characteristics, including size,condition, and composition. Based on anexpanded conceptual model of the optimalharvest rule, fish characteristics affect preand post harvest production yields and outputprices. A dynamic empirical model, which uses asystem of quality characteristics and anhedonic equation, illustrates the complexrelationships and management choices associatedwith internalizing seafood qualitycharacteristics in a hake fishery. The modelretains the regulated open access managementsystem, but controls intertemporal andintersectoral quotas, production portfolios,and total allowable catch. Results demonstratethat including revenue-side effects frominternalizing fish quality can generatesignificantly greater rents and reduce therelative benefits of increased productionyields. If excluded, bioeconomic models canunderestimate the level of regulatory rentdissipation and overemphasize managementobjectives such as full utilization, whichcould misdirect processing decisions and resultin a suboptimal resource management plan.Implications for data collection,multidisciplinary analysis, and improvements inmarine resource management are discussed.

The effect of management commitment to service quality on employees’ affective and performance outcomes

A service recovery performance model is proposed and tested with data from frontline bank employees in Turkey. The model is derived from Bagozzi's (1992) reformulation of attitude theory. The empirical results suggest that top management commitment to service quality, as manifested by frontline employees' appraisal of training, empowerment, and rewards, has a significant effect on their perceptions of service recovery performance. The influence of management commitment to service quality on service recovery performance is mediated by frontline employees' affective commitment to their organization and job satisfaction. Implications of the results and further research avenues are discussed.

从价值链到价值群的战略思维转变研究

曾经让企业发现竞争优势的价值链,如今变成了企业发展的绊脚石,束缚着企业管理者重构新的商业模式。在价值链的基础上设计价值群模型,对价值链进行破坏性创新,不破不立;当价值链已经成为企业发展的绊脚石时,对价值链的破坏,从原来的固定链式思维解脱出来,进入一种空间的立体结构运作模式已经成为不争的方向。价值群以其优于价值链的特征更适合现代商业环境的需要。

建筑垃圾处理与循环经济

建筑垃圾对环境的影响以及对建筑垃圾的资源化利用已成为亟待研究和解决的问题。循环经济把经济活动组成一个“资源一产品一再生资源”的反馈式流程,从而最大限度地减少经济活动对生态环境的影响。通过对建筑垃圾分类、组成和我国目前在处理方法上存在问题的分析,提出应用循环经济的“3R原则”资源化处理建筑垃圾的对策。     

2002年世界经济形势与中国的对策

2001年世界经济陷入了30年来最严重的衰退。这次衰退是继多年经济繁荣后的“硬着陆”,衰退导致世界经济增长曲线呈现“U”字型。从全球主要经济机构的预测结果看,2002年世界经济前景依然黯淡。世界经济的复苏,取决于美国经济的复苏,而美国经济复苏主要依靠扩张性政策的拉动,是政策导向型的复苏。面对严峻的外部经济环境,2002年中国经济要实现7%以上的增长,在立足于内需的同时,应对对外经济政策做适当的调整。     

基于感知价值的服务失误补救后顾客满意的实证研究

本文在资源交换理论的框架下，提出了一个基于感知价值的顾客补救后满意的整合模型，研究服务失误和补救服务属性的交互作用对顾客感知价值的影响，最终决定顾客补救后满意。研究表明，感知价值对顾客补救后满意有较强的解释作用，同时还证明了服务失误内容和补救服务属性之间的交互作用，确实对顾客感知价值有显著的影响。
