鼻内镜手术治疗慢性鼻窦炎患者115例护理分析

临床实践中,鼻内镜手术作为一种比较常规的鼻窦炎手术治疗方法,具有治疗效果显著的特征,且复发率低。本文主要就鼻内镜手术治疗慢性鼻窦炎患者115例患者的情况,对手术前和手术后的护理措施进行了分析和探讨。     

经济波动、超额准备金率和内生货币-基于信贷市场资金搜寻和匹配视角

本文基于信贷市场资金和项目的搜寻与匹配视角建立了一个内生货币模型,分析经济波动和货币政策对超额准备金率和货币乘数的影响。比较静态分析发现,超额准备金率具有逆周期特征;其变化有减弱法定准备金率和基础货币政策效果的作用。动态分析发现,超额准备金率具有滞后周期特征;超额准备金率的内生变化会带来货币政策的时滞效应。通过中国数据校准参数后的模拟发现,较高惰性的法定准备金率调整政策不仅不能有效抚平信贷市场波动,反而可能是造成信贷市场不稳定的原因。对中国数据的实证分析表明,超额准备金率的上述特征都具有很好的统计显著性。     

Dynamic efficiency assessment of the Chinese hotel industry

The paper introduces for the first time a totally dynamic two-stage approach to analyzing the hotel industry's technical efficiency at the sub-national level. The first stage uses data envelopment window analysis (DEWA) to assess regional hotel sectors' technical efficiency over time. Unlike previous studies, the second stage uses a dynamic Tobit model to investigate the impact of macro contextual factors on the hotel sector efficiency. The study chooses the Chinese hotel industry during the period 2001-2006 as its application setting. The findings of the investigation indicate that the Chinese hotel industry is approaching an efficient operation in general, recovering from a major dip in 2003 resulting from the Severe Acute Respiratory Syndrome (SARS) outbreak. In addition, the study introduces a novel two-dimensional efficiency-based matrix to assess the competitive advantage of different regions of the Chinese hotel sector. The paper presents strategic market implications for hoteliers, government decision-makers, and destination management organizations. The proposed methods are applicable for situations in which an exogenous event of a destabilizing impact (e.g., SARS) does occur.     

服务贸易出口、知识产权保护与经济增长

本文首先基于知识产权保护这一视角从理论上研究了服务贸易出口驱动经济增长的作用机理,并且认为,知识产权保护强化了服务业出口部门对其他部门所产生的外部经济溢出效应以及由此分解而来的要素配置效应和技术溢出效应。随后基于90个国家1998—2007年面板数据的经验研究表明:(1)技术与知识密集型服务业出口部门比劳动密集型、资本密集型服务业出口部门更加能够通过要素配置效应和技术溢出效应来促进经济增长;(2)相比于劳动密集型、资本密集型服务业出口部门而言,知识产权保护更加易于强化技术与知识密集型服务业出口部门的要素配置效应,但由于发展中国家的知识产权保护制度不够完善,这些国家服务贸易出口的要素配置效应未能得到强化;(3)不管对于发达国家还是对于发展中国家而言,知识产权保护均强化了劳动密集型、资本密集型、技术与知识密集型服务业出口部门的技术溢出效应。     

Does Marketing Activity Contribute to a Society’s Well-Being? The Role of Economic Efficiency

Does the level of marketing activity in a country contribute to societal well-being or quality of life? Does economic efficiency also play a positive role in societal well-being? Does economic efficiency also moderate or mediate the marketing activity effect on societal well-being? Marketing activity refers to the pervasiveness of promotion expenditures and number of retail outlets per capita in a country. Economic efficiency refers to the extent to which the economy is unhampered by corruption, burdensome government regulation, and a large informal economy. We used secondary data from the World Bank and other statistical sources to answer these questions. Our study findings suggest that both marketing activity and economic efficiency contribute positively to societal well-being, and that economic efficiency plays more of a mediator than moderator role between marketing activity and societal well-being. The public policy implication of this study is that increases in marketing activity and economic efficiency in countries characterized as low on both dimensions should significantly increase the quality of life in those countries.     

A framework for the selection of Six Sigma projects in services: case studies of banking and health care services in Taiwan

This study develops a framework for effectively implementing service Six Sigma projects. The framework is composed of four phases: (1) initial project identification, which deploys candidate projects in accordance with a firm’s strategic goals, (2) project value assessment, which evaluates project’s value based on the financial return, cost, and its impact on employee behavior, (3) project complexity assessment, which examines scope, data availability, and risk associated with the project, and (4) project prioritization, which identifies Six Sigma projects and categorizes them into black belt and green belt categories. Two cases in banking and health care services are discussed to demonstrate the proposed framework.     

油田电力配变网络优化及节能分析

针对新疆油田六、九区配电电网与负荷的不合理分配、配电变压器负荷率偏低、网损率不达标等现状,分别从提高变压器的负载率、运行效率、变压器优化组合配置和应用新型节能变压器等方面进行分析并提出具体改进措施。油区变压器的改造实践效果表明,相应措施均取得了可观的经济效益,达到了节能目的,对油田油区电网大规模改造和经济运行及管理具有重要意义。     

来自上市公司面板数据的企业核心能力测度

有效地计量企业的核心竞争力,是寻找如何提高企业竞争优势的前提条件。本文以2006—2010年深、沪两市有代表性的上市公司为研究对象,创造性地运用动态综合测度方法,通过对企业在较长时间序列里所表现出的价值性、成长性、稳定性进行计量,进而对企业核心能力的高低进行评价,以此来判断企业核心能力的强弱,并通过分析各测度指标和企业核心能力之间的关系,探讨提升企业核心能力的路径和方法。
