经桡动脉与股动脉途径行急诊PCI护理的比较分析

目的对比急性心肌梗塞(Acute myocardial infarction,AMI)患者经桡动脉与股动脉穿刺行急诊冠状动脉介入(Emergency percutaneous coronary intervention,PCI)治疗护理的优缺点。方法 2011年1月至2011年12月我院行急诊PCI治疗102例AMT,其中经桡动脉冠状动脉(Transradial coronary intervention,TRT)介入组53例,经股动脉介入(Percutaneous coronary intervention,TFT)49例。对比其术后并发症的发生率、住院天数、护理量、术后患者心理躯体舒适度等进行统计学数据与分析。结果两组病例基本特征比较差异无统计学意义,而并发症则经桡动脉组低于股动脉组(3.8%VS8.2%P<0.05),患者住院时间明显短于股动脉组(P<0.05),护理人员工作量也明显少于股动脉组(P<0.05),术后患者的心理躯体舒适度评估明显高于股动脉组。结论经桡动脉途径行急诊PCI治疗是安全、有效的方法。与股动脉途径比较,经桡动脉途径可减少并发症的发生,缩短住院天数,患者恢复快,减轻护理工作量,节约护理资源,不但有益于患者,亦有益于护理人员。     

Design and application of task administration protocols for collaborative production and service systems

This research investigates the design of Task Administration Protocols (TAPs) for effective task allocation and administration in collaborative production/service systems. Customer-focused and concurrent engineering service systems process tasks more effectively as a result of the power of collaboration among multiple participants. In such environments, however, complex situations might arise that require decisions that cannot be handled by simple Coordination Protocols (CPs). To design an effective control mechanism to manage complex situations, this research identifies basic problems in collaborative task administration and proposes the design framework of protocols to solve the problems. In the framework, TAPs consist of three component-protocols: (1) Task Requirement Analysis Protocol, (2) Shared Resource Allocation Protocol, and (3) Synchronization and Time-Out Protocol. Each component protocol is activated to address priority-based allocation, resource-aware allocation, and task re-allocation at a different task administration context, ranging from task initialization, task allocation, to task monitoring, respectively. To analyze feasibility and effectiveness of the proposed design, TAPs are applied to two collaborative production/service systems. Simulations are conducted to evaluate the performance achieved by different TAPs and non-TAP CPs under various load conditions. The results show that there is a significant performance improvement by TAPs over CPs in most cases, e.g., 84% vs. 64% in terms of task completion ratio. The advantage of TAPs can be explained by their design with relatively higher level of collaborative intelligence, addressing more complex control logic than non-TAP CPs.     

How do independent directors influence innovation productivity? A quasi-natural experiment

Due to managerial myopia, managers may be reluctant to make long-term investment decisions that do not produce immediate results. Effective corporate governance can align managers’ short-term-oriented incentives with shareholders’ long-term interests. Because the board of directors is the paramount governance mechanism, we explore the role of board governance on managerial myopia. In particular, we investigate the effect of independent directors on corporate innovation. To minimize endogeneity, we exploit the passage of the Sarbanes–Oxley Act as an exogenous shock that raises board independence. Our difference-in-difference estimates show that board independence leads to significantly higher investments in innovation as well as higher innovation productivity. Our results are consequential as they show that board governance has a palpable effect on important corporate outcomes such as innovation productivity.     

Success factors of platform leadership in web 2.0 service business

The purpose of this study is to investigate the critical success factors of platform leadership in the Web 2.0 based service business environment. Because of the lack of theoretical foundation for this topic, we adopted relevant theory and case study analyses. Representative Web 2.0 firms which have developed platform leadership were chosen and analyzed on the basis of previous research on platform strategy through spider web analysis. This study shows that Web 2.0 firms such as Google, Flickr, and Salesforce.com differ in their competitive capabilities for platform leadership. The result of this research suggests that platform leadership in the Web 2.0 era depends on five interdependent dimensions: innovation ability, connectivity, complementarities, efficiency, and network effects.     

An object-oriented optimal savings system: HYPER-SAVINGS

This research develops an intelligent dynamic savings investment system called HYPER-SAVINGS which can construct the best savings portfolio embracing all types of products from multiple banks. Since the major model in HYPER-SAVINGS is the 0–1 integer programming (IP) model, we need to interpret information about investors, products, institutions and the current financial situation for the formulation of the IP model. This has become possible by adopting the knowledge-based integer programming modeling aid, UNIK-IP, which allows the formulation of an IP model at a semantic level using logical operators such as EITHER–OR and IF–THEN, and automatically transforms them to a so-called base level model which can be solved by the IP solver. HYPER-SAVINGS also provides the capability of sensitivity analysis at a semantic level to adjust to dynamic situational changes. Since the system is expected to collect the information from various banks through the Internet and filters out dominated products before formulation, HYPER-SAVINGS can provide the architecture for the international meta-bank on the Internet. © 1997 John Wiley & Sons, Ltd.

新旧企业会计准则债务重组的比较分析

新旧会计准则在债务重组的定义、入账价值属性、债务重组方式以及会计处理等方面有较大不同。新准则下企业进行债务重组,债务人多确认债务重组收益,从而增加当期利润;债权人多确认债务重组损失,从而减少当期利润。     

Have Industrial Robots Improved Pollution Reduction? A Theoretical Approach and Empirical Analysis

To investigate whether industrial robots have improved the ecological environment, this study integrated the adoption of robot technology and pollution abatement into Melitz's heterogeneous firm model. This showed that using robots in production can lower firms' pollution intensity by increasing their abatement investments, and this reduction effect is greater for higher polluting firms and those subject to weaker local environmental regulations. These theoretical expectations were then confirmed through a series of empirical investigations based on Bartik instrument regressions, with multiple robustness checks as well as heterogeneity and mechanism analyses. This paper adds to the literature on the relationships between automation technologies and green transformation. It shows that in the pursuit of economic growth and environmental protection, it is necessary for policymakers to shift from pollution control to technical support for traditional manufacturing firms.
