On the optimality of a class of minimal covering designs

It is shown that the minimal covering designs for v=6t+5 treatments in blocks of size 3 are optimal w.r.t. a large class of optimality criteria. This class of optimality criteria includes the well-known criteria of A-, D- and E-optimality. It is conjectured that these designs are also optimal w.r.t. other criteria suggested by Takeuchi (1961).     

Prioritization of sustainable supply chain practices with triple bottom line and organizational theories: industry and academic perspectives

Abstract

The purpose of this study is to investigate the influence of sustainable supply chain management (SSCM) practices on triple bottom line (TBL) measures from the perspective of organizational theories. This study identified five SSCM practices using a comprehensive literature review and feedback from industry experts. These five practices were prioritized using a fuzzy analytical hierarchy process (FAHP). The results from FAHP analysis were further confirmed by conducting semi-structured interviews in five electronics parts/components manufacturing organizations. This study also prioritized theoretical drivers of SSCM adoption based on the consideration of three organizational theory perspectives – Institutional Theory; Resource-Based View, and; Social Network Theory. The results indicate that the economic dimension was the most important measure for implementing SSCM while sustainable design was the most important SSCM practice for achieving the TBL. The study also found that Institutional Theory is the most important theoretical driver for implementing SSCM. The research findings provide insight for management to allocate necessary resources and to develop effective strategic directions for the implementation of SSCM practices.     

沈从文物质文化史研究与三重证据法的理论与实践

从文学转治文物的沈从文是三重证据法(传世文献、出土文献与出土文物相结合)的最早倡导者与实践者之一。他不仅在理论上阐述了文史研究必须结合文物,而且熟练运用这一方法取得了文献、文物研究的辉煌成果,并进一步阐述了深入研究与人才培养的方法。沈从文的文学成就掩盖了其物质文化研究的卓越贡献,以后的沈从文研究应当还原他作为一名史学家的真实面目和历史地位。     

论徐中舒的“澄滤”说与古史建设理论

徐中舒先生的史学,直接继承了中国传统史学的考据方法,并受到王国维、梁启超、陈寅恪、李济等学术思想的深刻影响。他运用"澄滤"说和"素地"论对于上古时期文献记载和古史传说的发生及其演变过程进行分析,更具科学和理性。"古史三重证"的方法论为"澄滤"说提供了可靠的保证。     

FDI对我国三次产业影响作用的实证分析

利用自回归分布滞后(ADL)模型,结合我国1983到2006年的有关数据,对我国FDI对三次产业的影响作用作出实证分析,得出结论,FDI在短期内对我国经济增长起了较大的促进作用,但长期作用不显著.并结合我国经济现状分析了原因,提出要充分发挥其在经济增长中的作用,需调整FDI在三次产业之间以及产业内部的投资结构.     

“三重底线”下中国商业银行经营效率及其影响因素分析

银行业在我国经济中扮演着重要的角色。在现今可持续发展理念的倡导下，单一维度的银行效率评价已经难以适应时代的需要。为此，本文基于"三重底线"视角分别构建了中国商业银行经济、社会与环境效率指标，通过SBM-DEA模型对中国商业银行的"三重效率"进行了测算分析，并运用SBM-Pearson分析法初步揭示了中国商业银行三重效率间的关系，之后再利用SBM-SUR计量模型对影响中国商业银行三重效率的因素作了进一步的探究。研究结果表明：（1）中国商业银行中股份制商业银行与城市商业银行在经济效率、社会效率上表现突出，而国有商业银行表现不佳。但是在环境效率方面，国有商业银行后来居上表现强劲。（2）中国商业银行间三重效率并不存在相互冲突，社会效率、环境效率与经济效率之间有着显著的正相关关系，但是并没有发现社会效率与环境效率之间存在显著的联系。（3）在经济效率方面，资产规模、运营年限、银行类型以及资产回报率均对其有着显著的正向影响；不同的银行类型对社会效率有着不同程度的显著影响；在环境效率方面，资产规模与银行类型也对其影响显著。     

Lean Six Sigma applied to process performance and improvement model for the development of electric scooter water-cooling green motor assembly

Abstract

In response to the environmental issues triggered by global warming, worldwide companies gradually put the factor of carbon emission into the process of product lifecycle, developing green technology or adopting cleaner production aimed at sustainable development. Lean Six Sigma has advantages of cutting waste and facilitating process improvements as well as system analysis, helping enterprises create the overall business benefits in the value chain. Used in the renewable energy industry, it can promote the triple bottom line (TBL), the performance of sustainable production for corporate profit, social responsibility and environmental responsibility. Therefore, this work took the process performance of the electric scooter water-cooling green motor manufactured in Taiwan with the world’s highest density of scooters as a case study. The developed performance evaluation and improvement model for manufacturing scheduling and process quality achieved the goal of economic benefits of enhancing process quality performance by shortening manufacturing scheduling and reducing process variations with Lean Six Sigma. Besides, they could respond to the policy of energy saving and carbon reduction – replacing the traditional scooters of high-carbon emissions with the electric scooters of low emissions. Furthermore, they could bring enterprises into harmony with economic benefits, ecological benefits and social benefits.     

三螺旋模式与知识经济

大学、产业与政府三者之间关系构成了一个三螺旋模型，可将此关系网络的新体制模型推广为三种选择环境如何相互作用的新进化模型。两种相互作用的选择机制能形成一个轨道，而三个选择环境则有望生成一种管理制度。通过新进化模型既可理解大学、产业与政府三者间关系的机构整合，又可理解财富创造、知识生产和立法等功能的不同。对于国家、部门和区域创新系统的说明便可以确切地阐述为一个实证问题：协同是否由关系网络的不同功能而产生？由此，该三螺旋模型使我们能在全球层次上，根据局部稳定（和潜在锁定）轨道之间的权衡，对比技术经济制度，研究某种经济的知识基础。     

Efficient sequential estimation in a markov branching process with immigration

Sequential estimation of parameters In a continuous time Markov branching process with Immigration with split rate λ₁ Immigration rate λ₂, offspring distribution {p₁j≥O) and Immigration distribution {p₂j≥l} is considered. A sequential version of the Cramér-Rao type information inequality is derived which gives a lower bound on the variances of unbiased estimators for any function of these parameters. Attaining the lower bounds depends on whether the sampling plan or stopping rule S, the estimator f, and the parametric function g = E(f) are efficient. All efficient triples (S,f,g) are characterized; It Is shown that for i = 1,2, only linear combinations of λ_ip_{ij j}'s or their ratios are efficiently estimable. Applications to a Yule process, a linear birth and death process with immigration and an M/M/∞ queue are also considered
