英语人体成语的隐喻性

人体各部位和器官被先民用作媒介命名和认知客观世界。这是基于哲学体验主义的隐喻认知观。英语人体成语的隐喻方式可分为"人体域投射于具体域"和"人体域投射于抽象域"两大类。

Performance of spare parts supply chains in developing industries

Spare parts supply chains of manufacturing equipment in developing industries such as the Saudi manufacturing sector often operate in one direction. Importing production machinery and setups to run such developing industries, from more developed industrial countries, sway the flow of spare supplies upstream. Based on empirical data collected from 210 local manufacturing firms, this study characterises and models such supply chains. The effects of supplier proximity, diversity and time lag on spare parts supply chain performance were explained using structural equation modelling. Delivery time lag and supplier diversity increased the deficiency of spare parts availability. Opposite to earlier consensus found in the literature, the impact of supplier proximity on spare parts supply chain performance was insignificant. Recent improvements in the agility and capacity of logistical services might have diminished the influence of supplier remoteness. However, supplier proximity correlated with supplier diversity in such supply chains.     

Benzene Inhalation by Parts Washers: New Estimates Based on Measures of Occupational Exposure to Solvent Coaromatics

Questions persist regarding assessment of workers’ exposures to products containing low levels of benzene, such as mineral spirit solvent (MSS). This study summarizes previously unpublished data for parts‐washing activities, and evaluates potential daily and lifetime cumulative benzene exposures incurred by workers who used historical and current formulations of a recycled mineral spirits solvent in manual parts washers. Measured benzene concentrations in historical samples from parts‐washing operations were frequently below analytical detection limits. To better assess benzene exposure among these workers, air‐to‐solvent concentration ratios measured for toluene, ethylbenzene, and xylenes (TEX) were used to predict those for benzene based on a statistical model, conditional on physical‐chemical theory supported by new thermodynamic calculations of TEX and benzene activity coefficients in a modeled MSS‐type solvent. Using probabilistic methods, the distributions of benzene concentrations were then combined with distributions of other exposure parameters to estimate eight‐hour time‐weighted average (TWA) exposure concentration distributions and corresponding daily respiratory dose distributions for workers using these solvents in parts washers. The estimated 50th (95th) percentile of the daily respiratory dose and corresponding eight‐hour TWA air concentration for workers performing parts washing are 0.079 (0.77) mg and 0.0030 (0.028) parts per million by volume (ppm) for historical solvent, and 0.020 (0.20) mg and 0.00078 (0.0075) ppm for current solvent, respectively. Both 95th percentile eight‐hour TWA respiratory exposure estimates for solvent formulations are less than 10% of the current Occupational Safety and Health Administration permissible exposure limit of 1.0 ppm for benzene.     

武器装备保障供应链中基于绩效的整体外包机制

传统的武器装备保障是军方体制内的保障,供应商只负责提供装备,因
而供应商没有动力提高装备可靠性,保障成本也比较高。针对这种弊端,本文提
出了一种基于绩效的保障服务整体外包模式,即由供应商负责从提供装备到完成
装备保障任务的整个供应链,军方根据保障的绩效水平通过合同进行一定的奖励
和惩罚。本文运用委托代理的研究模型,分析了这种保障模式的优势。结果表明,
军方一定的激励政策可以引导供应商努力提高装备可靠性,并使其获得更好的收
入;与此同时,军方保障的总成本也得到降低,供应链绩效得到改善。

语文词典词类标注的一致性原则

语文词典的词类标注是一项复杂的系统工程,在实施这项系统工程的过程中,必须自始至终贯彻一致性原则,其中包括词类标注与释义的一致性、词类标注与配例的一致性、词类标注与同类词的一致性等。几部影响较大的现代汉语词典在词类标注方面取得显著成就,但同时也难免存在一些失误,一致性原则贯彻不够彻底就是导致这些失误的重要原因之一。

How organizations work: Taking a holistic approach to enterprise health

The factors that facilitate organizational learning have traditionally been analysed by organizational learning and, in particular, the learning organization literature. Following a literature review, we have identified fifteen factors. However, these factors have been considered as universal, in other words, applicable to any sector or industry. In this paper we determine the combinations of organizational learning facilitating factors in a specific sectoral context: the Spanish ceramic tile sector, through an exploratory and comparative case study of four companies that illustrate this sector. In addition, we relate the companies' combinations of factors to their strategies (Miles and Snow 1978). The study mainly reveals that: each business strategy category is related to certain factors; the organizations with the most facilitating factors are the most innovative (prospector and analyser); and becoming a prospector implies the distinctive existence of factors 1 and 2, which encompass openness to and capacity for innovative change, a culture that favours the contribution of discerning ideas and maximum attention to the environment.     

中国在亚洲生产网络格局中的地位和作用

综观亚洲一体化的进程,发展最快的内容是亚洲生产的一体化.亚洲生产对亚洲凸显重要,那么,亚洲生产的中心是谁呢?即亚洲生产更依赖哪个国家和地区?这是一个大家非常关心的问题,文章依据亚洲零部件贸易数据,对亚洲生产网络的演进进行了研究,同时,采用了依存比率的方法对亚洲生产网络的规模、生产网络内部以及同美国之间的相互依存关系进行了研究.研究结果发现,在亚洲生产网络的演进进程中,起关键作用的是中国,而且,到2010年,亚洲工厂是世界上最大的工厂,亚洲生产网络的中心是中国,其次是中国香港,日本只居第三位;亚洲生产网络对于美国的依赖程度并不高,远远低于亚洲生产网络对中国内地和香港的依赖,这说明中国是亚洲工厂的核心平台.
