基于Mo-RVIKOR的混合多属性决策方法

针对复杂性和不确定性多属性决策问题,考虑定量和定性融合的属性形式,提出了模块化随机多准则妥协解排序法（Modular Random VlseKriterijumska Opti-mizacija I Kompromisno Resenje,Mo-RVIKOR）,该方法无需将信息统一,就能处理多种信息形式存在的多属性决策问题。采用精确数、随机变量处理定量评价信息,用概率语义术语集处理定性评价信息;通过改进离差最大化法确定属性权重;根据Mo-RVIKOR对决策对象进行排序;最后以某公司C2B定制化服务质量评测项目为例,验证了所提方法的有效性。     

Did small and medium enterprises maintain better jobs during the early years of the recession? Job quality multidimensional evidence from Spain

While the literature has indeed confirmed a general tendency linking small and medium enterprises (SMEs) to a dynamic of greater job creation, there is little available evidence on what has happened to job quality since the financial crisis. Through a representative sample of 5311 employees in 2008 (first year of job destruction) and 4925 employees in 2010 (last year for which data were available), and using a two-stage structural equation model, this article empirically analyses the multidimensional determinants of job quality, by enterprise-size class, in Spain. The research has revealed three main results. First, job quality in Spain improved in all enterprises, regardless of their size, during the early years of the recession. Second, the greatest improvements were found in SMEs. Although job quality was already better in SMEs than in large enterprises in 2008, the differences between them subsequently widened. Third, this accelerated divergence was explained by the following dimensions: working conditions, work intensity, health and safety at work, and work–life balance. These dimensions were much more positive in SMEs. Employment-related public policy should therefore focus more specifically on SMEs. There are two reasons for this. First, despite the recession, SMEs have shown themselves to be key factors in the explanation of job quality. Second, by making changes to their value generation model, they could continue to drive the creation of better quality jobs.     

Effects of key enabling technologies for seru production on sustainable performance

Demand uncertainty, economic globalization, and environmental deterioration force factories to innovate their manufacturing systems for achieving sustainable performance. Seru production, which is the latest manufacturing mode developed in Japan, attracts broad attention from both academia and practitioners. The overwhelming majority of existing works on seru production focus on economic performance unilaterally, while neglecting the environmental and social performance. This paper investigates the effects of key enabling technologies for seru production on sustainable performance. Firstly, four key enabling technologies for seru production are identified through systematic review, and an evaluation indicator system of sustainable performance in the context of seru production is developed. Then, the hypotheses about the effects of the identified key enabling technologies for seru production on sustainable performance are proposed on the basis of previous research achievements, theoretical analysis, and practical observations. Finally, the hypotheses are tested through structural equation modeling. Except for two hypotheses which are not supported and one which is indirectly supported, all other hypotheses are verified. The research results show that the four key enabling technologies for seru production have different effects on the three dimensions of sustainable performance. The achievements of this work are of significance to improve the comprehensive understanding of seru production, as well as to develop practical methods to implement sustainable operations.     

光滑暧昧模型下的不透明交易和管制措施研究

本文假定透明交易者对额外投资机会回报率的标准差(方差,投资风险)存在暧昧,这种认知暧昧性抑制了透明交易者的投资行为,会导致风险资产溢价过高及社会福利损失.透明交易者是暧昧厌恶的投资者,其投资决策依据光滑暧昧厌恶模型,需求函数呈现连续且光滑的特征.而不透明交易者,通过支付一定的信息获取成本获得私有信息而具有信息优势,他们是标准的风险厌恶的投资者.通过构建理性预期均衡,本文的研究发现:初始资产严格为正的透明交易者将获得严格为正的超额收益;提高信息获取成本将减少不透明交易者的比例,从而增加风险资产溢价,降低福利水平,因而不是一项好的管制措施;而旨在提高市场透明度降低交易者暧昧性的举措总有利于提高福利水平.     

The Impact of Competitive Strategy and Supply Chain Strategy on Business Performance: The Role of Environmental Uncertainty*

This article investigates the relationships among competitive strategy, supply chain strategy, and business performance while examining the moderating effect of environmental uncertainty. A total of 604 questionnaires were collected from three cities in China, and the statistical results show significant moderating effects of external environment on the relationships among competitive strategy, supply chain strategy, and business performance. Firms that primarily focus on a differentiation strategy emphasize an agile supply chain strategy. Cost leaders are inclined to implement both lean and agile supply chain strategies, but their emphasis on agile strategy is significantly greater in a volatile environment than in a stable environment. The choice of supply chain strategy does not appear to be an “either‐or” decision and firms could adopt either a lean or an agile strategy, or both, depending on the environment. This article provides significant managerial implications for supply chain practitioners to co‐align supply chain strategy and competitive strategy with the environment to improve performance.     

股指期货价格非线性均值回复特性实证研究

用ESTAR 模型对香港恒生指数期货933、9312、943 合约及S&P 500 指数期货933、9312、 943 合约价格进行了实证研究,发现恒生指数期货933、9312 合约实际价格呈现非线性均值回 复,而其他各合约实际价格呈现线性均值回复. 结论:由于股票现货没有卖空机制使套利成本 较大,抑制了套利行为,导致期货合约实际价格呈现非线性. 在股票现货没有卖空机制的市场 条件下,单向套利的机会要比成熟的市场更多.     

On the Measurements of Board Composition: Poor Consistency and a Serious Mismatch of Theory and Operationalization

Over two dozen operationalizations of board composition can be identified from the empirical literature. A structural equations confirmatory factor analysis (LISREL 8.03) suggests that these operationalizations do not constitute a single construct of board independence. Instead, analyses strongly indicate three separate constructs. Common operationalizations of board composition, then, are neither tenable surrogates for one another nor are they interchangeable. Implications for empirical aggregation of studies, theory/measurement convergence, and the current corporate governance public policy debate are discussed.     

A cross-validation of a structural equation model of accidents: organizational and psychological variables as predictors of work safety

A study to establish a structural equation model of accidents is presented. The eight variables included in the model were those associated with accidents in previous research. The reliability of questionnaires to measure those variables and a structural equation model relating them are provided. The model explaining the occurrence of accidents was cross-validated through three Spanish samples (n=123; 182; 124).The model presented a good fit to data in two samples, while a third had unclear fit indices. Therefore, most relationships among variables did not vary among these three samples. The role of the safety variables in the model is discussed. The discussion is also focused on risk measurement difficulties commonly reported in the literature. Finally, some suggestions for future safety research with structural equation modelling techniques are provided.     

青年领导干部要增强宪法意识纪念1982年宪法实施20周年

目前,青年领导干部中表现出来的宪法意识偏差主要表现为轻视宪法学习、缺乏宪法信仰;忽视宪法特性,降低宪法地位.相伴而生的主要违宪行为即是违背宪法精神、超限行使权力;违反宪法规定,侵犯公民权利.因此,必须要以有计划的培训考核;推动青年领导干部学习"三个代表"思想与宪法精神的一致性、学习宪法条款;强化人民民主与权利观念;以转变领导方式和工作方法去落实依法行政;发挥学习、遵守、使用宪法的表率作用.     

土地革命战争时期共产国际“左”倾错误理论发端新探

土地革命战争时期 ,在共产国际“左”倾理论的指导下 ,中共先后出现了三次“左”倾关门主义错误。依马克思主义的政党理论 ,国民党不仅是一个政党 ,而且是一个资产阶级性质的政党。而共产国际视资产阶级性质的国民党为统一战线的组织形式 ,从而割裂了国民党与资产阶级间的密不可分的联系 ,必然在认识上出现一误区 ,即将大资产阶级与民族资产阶级、小资产阶级混为一谈。一旦大资产阶级叛变革命 ,共产国际便视民族资产阶级、小资产阶级破坏统一战线 ,从而打击它们。
