罗布麻针织物性能测试与研究

随着人们生活水平的提高和对健康理念的逐步深入,对针织产品的舒适性和功能性要求也逐步提高,具有天然抗菌效果的罗布麻纱线被越来越多的应用到针织产品中。本文选取了100%纯罗布麻纱线和其它三种针织产品中常见的纱线——纯棉、纯羊毛和纯腈纶纱线,通过电脑横机以相同的编织参数编织成满针罗纹织物,然后对织物进行面密度、透气性和悬垂性等性能的测试,从而比较罗布麻针织物和其它纱线针织物的各项性能指标。`     

顾客维度的政府绩效评估体系及其构建

政府绩效评估是近年来政府管理领域备受关注的主题。但传统的政府绩效评估在评估的价值取向、评估主体、评估指标设计以及评估结果使用等方面仍缺乏顾客维度的关怀。文章对此问题进行研究,提出构建顾客维度的政府绩效评估体系的设想,并在分析其意义与可行性的基础上提出系统的可操作性建议。     

十年反恐对美国及世界政治的影响

2011年5月1日基地组织头目本.拉登被美国击毙。从某种意义上说,这标志着美国十年反恐之路的终结。文章通过比较9.11事件前后的反恐战略来分析十年反恐给美国及世界政治造成的深刻影响。9.11前的美国反恐主要针对其认定的某些＂支恐＂国家。9.11事件发生后,恐怖主义是美国国家安全的最大威胁,美国出台了反恐战略,发动了阿富汗和伊拉克两场战争。美国反恐付出了巨大经济代价,使中东更加动荡不安,也给新兴发展国家提供了崛起的历史机遇。

Work and social well-being: the impact of employment conditions on quality of life

This paper aims to extend our understanding of the impact of management practises and employment conditions in the contemporary workplace on the broader social realm. The study provides an analytic account of how these employment conditions impact on the social well-being of a representative sample of individuals and households. We assess the propensity of working arrangements that are manifested in various high performance work systems either to enhance or to diminish quality of life. The paper indicates that certain management practises and employment conditions have impacts that extend beyond the workplace and influence the broader well-being of individuals and families.     

Measuring Corporate Environmental Performance: A Methodology for Sustainable Development

Assessing corporate environmental performance (CEP) that is both comprehensive and consistent with sustainable development both for society and companies, while at the same time taking heed of the facts and interests of each stakeholder, is not a simple feat. Due to the multidimensional character of the sustainability concept, several questions must be considered in the evaluation process: (i) the qualitative nature of indicators and the complexity of developing a synthetic index; (ii) the difficulty of choosing properly statistical techniques for aggregation and (iii) the difficulty of introducing stakeholders’ preferences in the assessment models. This paper is an attempt to address this challenge by developing a framework for the assessment of CEP, based on the application of a fuzzy multi‐criterion decision‐making (MCDM) method. To achieve positive scores in a CEP assessment, an organization should be strategically committed and engage in environmental management and governance structures that are translated into good results in terms of both engagement and operational performance. Unless such premises are explicitly incorporated into the assessment criteria, the results would reveal that the CEP measurement could not be brought into a line with an earnest ambition of achieving true sustainable development.

Behind managerial reforms: the French experience

Inspired by new public management (NPM), managerial reforms in many countries from the 1990s onwards focused on three criteria: effectiveness, efficiency and enhancing service quality. These criteria were meant to be given equal weight in measuring performance, but this paper shows that some criteria dominated. The reform experiences of four countries are compared, with a focus on French reforms.     

Product configuration,ambidexterity and firm performance in the context of industrial equipment manufacturing

The practice of configuring products to individual customer orders has found application in a variety of industry contexts, but little is known about the specific capabilities that firms develop to successfully compete when offering configurable products. Our research begins to fill this gap in the context of industrial equipment manufacturing. Drawing from the ambidexterity literature, we argue that firms have to balance dual goals of reducing variation and promoting variation in their product configuration activities by fostering two distinct firm-level capabilities: product configuration effectiveness (PCE) and product configuration intelligence (PCI). Specifically, we hypothesize that the simultaneous presence of PCE and PCI—that is, product configuration ambidexterity (PCA)—drives superior firm responsiveness and, indirectly firm sales and operating margin. However, we also contend that responsiveness gains through PCA can diminish with product complexity and can increase operating cost. We test these hypotheses by collecting both primary and secondary data from a sample of 108 European industrial equipment manufacturing firms. Results from our analyses indicate that PCA has an indirect effect through responsiveness on sales and operating cost but not on operating margin, with this effect diminishing with product complexity. Taken together, our results suggest that investment in developing PCA may represent a conundrum for industrial equipment manufacturing firms, because it translates into market but not financial advantages, and it is intertwined with product design decisions. We conclude this study with a discussion of the findings for theory and practice.
