Evaluating the Gauge Repeatability and Reproducibility for Different Industries

Measurement plays a significant role in Six sigma program. Usually, the gauge repeatability and reproducibility (GR&R) study needs to be conducted prior to the process capability analysis for verifying the accuracy of measuring equipments and helping organizations improve their product and service quality. Therefore, how to ensure the quality of measurement becomes an important task for quality practitioners. In performing the GR&R study, most industries are using the acceptance criteria of Precision to Tolerance(P/T) ratio as stipulated by QS9000. However, the adequacy of applying the same acceptance criteria to different manufacturing processes is very questionable. In this paper, a statistical method using the relationship between GR&R and process capability indices is proposed for evaluating the adequacy of the acceptance criteria of P/T ratio. Finally, a comparative analysis has also been performed for evaluating the accuracy of GR&R among three methods (ANOVA, Classical GR&R, and Long Form). Hopefully, the results of this research can provide a useful reference for quality practitioners in various industries.     

Measuring the Comparability of Company Accounts Conditionally: A Research Note

Comparability indices summarize the level of comparability between companies at a national and international level, an issue of importance to investors, regulators, and standard setters. Comparability indices can identify areas where comparability is low and where comparability is deteriorating. Furthermore, they can be used to quantify the extent to which initiatives such as International Financial Reporting Standards (IFRS) are successful in raising comparability between company accounts. Despite past literature emphasizing how factors other than country influence accounting methods used by companies, current comparability indices ignore these other factors. This paper introduces new national and international indices within the T index framework to fill this gap in the literature. Formula for the new national and international indices, and their standard errors, are provided. An example using European data is used to demonstrate the calculations and illustrate the importance of controlling for these firm specific factors.     

对《国标》中旅游评价赋分标准的思考

旅游资源是旅游业发展的基础,旅游资源的分类、调查、评价是旅游业发展过程中的重要环节,也是旅游资源开发的基础和前提。国家标准GB／T18972-2003《旅游资源分类、调查和评价》的制定与推行,为地方旅游的发展提供了规范性的文本,各级旅游部门都以此为依据开展工作,但各地在应用的过程中。也发现该标准存在诸多问题．从旅游规划实践中的旅游资源评价出发,运用对比分析方法及文献资料法,对《国标》中旅游评价赋分标准存在的若干问题进行了分析,认为《国标》中存在主观性、局限性及不完善性,在此基础上．提出了对其进行改进的建议．     

关键核心技术产学研协同创新机理研究——以芯片光刻技术为例

产学研协同创新是突破关键核心技术“卡脖子”问题、实现科技自立自强的重要途径,但鲜有研究揭示面向关键核心技术创新的产学研协同机理。基于复杂系统管理理论,构建关键核心技术产学研协同创新机理系统框架,揭示产学研非线性互动协同创新规律,并以芯片光刻技术为例,借助社会网络分析法实证解析该框架。研究发现：(1)资源整合—主体交互—系统涌现是基于复杂系统管理视角提升产学研协同网络成效、加快关键核心技术突破的有效途径;(2)主导者—桥梁—辅助者权力分配规则能够有效促进多元主体在交互过程中通过嵌入性社会关系推动关键核心技术创新的价值增值;(3)模块化—松散耦合的网络结构能够消除主体间交互障碍、最大化结构红利,是产学研协同复杂网络在系统结构层面涌现的关键核心技术创新突破规律。最后,通过芯片光刻技术专利合作网络实证解析关键核心技术产学研协同创新机理,提出强化面向关键核心技术产学研协同创新、助力高水平科技自立自强的对策建议。

T·S·艾略特新批评文学观及其意义

T.S.艾略特新批评是对传统批评的反驳,将文学批评从作者引向文本;艾略特新批评主要观点是“非个性化”和“意象表现”;以诗歌与文论为新批评拓荒,为现代诗歌拓荒,从而成为新批评奠基人、现代诗歌先驱。     

政府补助对战略性新兴产业创新效率影响研究

以信息技术产业作为战略性新兴产业的代表,围绕政府补助与企业创新这一基本问题进行探讨,并创造性地研究了政府补助对企业创新效率的具体影响。研究发现,政府补助对刺激企业创新活动具有明显作用,并能显著提高企业创新产出和创新效率。国有企业较非国有企业更愿意进行R&D活动,也提供了更多创新产出,但政府补助并没有对企业经营效率产生显著影响。企业所有权性质对企业创新和经营效率均不具有显著影响。     

T+1制度对中小投资者保护效果的实验研究

为了保护中小投资者,我国股票市场于1995年开始执行与国外主要市场有着显著差异的T+1交易制度。20多年以来,该制度的有效性一直饱受争议。本文利用实验经济学的方法构建了T+0和T+1制度的股票市场,并利用收集到的市场层面和个体行为层面的数据对这两种制度进行了对比分析。研究发现,相对于T+0制度,T+1制度保护的并不是中小投资者,而是大投资者。而且,T+1制度显著减少了市场的成交量,不但不能明显地降低市场泡沫,还加剧了市场价格的波动。研究还进一步发现,T+1制度还保护了具有较高风险偏好水平的投资者,避免了这类投资者的频繁交易。
