The structure of employee attitudes to safety: A European example

This paper concerns organizational safety culture and the structure or architecture of employee attitudes to safety as part of that culture. It begins by reviewing the somewhat scant literature relevant to this area, and then reports a study, conducted in a European company, which collected and factor analysed data on employee attitudes to safety. The framework provided for the study was that offered by Purdham (1984), and the results suggested that employees' attitudes to safety, within this company (across occupation/occupational level and country), could be mapped By five orthogonal factors: personal scepticism, individual responsibility, the safeness of the work environment, the effectiveness of arrangements for safety, and personal immunity. The theoretical and practical implications of these findings are discussed, and attention is drawn to their subsequent use in an intervention to enhance safety culture within the organization by attacking supervisors' attitudes to safety.     

Fire Risks in Oil Refineries: Economic Analysis of Camera Monitoring

A probabilistic method is presented to evaluate the economic value of fire monitoring by closed circuit TV camera in petroleum refineries. The proposed model is restricted to the analysis of risk reduction in an area where fires can be caused either by pump failure or by failure of valves and lines. The benefits come from reducing the time during which the fire grows undetected. Fire growth and expected values of losses are analyzed by a Markov model that includes five phases: (1) active undetected growth, (2) detection, (3) fire growth at the beginning of the firemen's intervention, (4) fire control, and (5) fire extinction. The results (e.g., the expected net present value of the investment) show that the proposed monitoring investment is attractive for an illustrative example.     

从Fletcher对孟郊一首五言诗的翻译谈话语分析方法

根据翻译的特性对话语建构的七项原则给予阐述并将之运用于Fletcher翻译的唐朝诗人孟郊的五言诗《古别离》。话语分析对语言组织特征和使用特征进行动态研究而不是结构本身的静态描写。它对翻译理论和实践具有实际性的指导意义     

翻译中分析的对象与分析的参照物

奈达把翻译的过程分为分析 -转化 -重组三个步骤。本文通过区分及分析翻译过程中分析的对象与分析的参照物 ,论证了在绝大部分情况下 ,整个语篇不是也不必是译者分析的对象 ,它只起语境的作用 ,从而证明了翻译中“句本位”的合理性     

短期物流整合情形下的供应商评价模型

在供应链管理(SCM)和虚拟制造组织(VMO)中,供应商的评价和选择是一个研究的热点;近年来已有学者提出,用主观方法来评价和选择供应商和实践是有差异的;本文从实际数据出发,针对发展中国家常见的短期物流整合情形,试图提出一个系统分析模型来探讨这个问题。     

基于Vague集和属性综合评价的股票投资价值分析方法

对二级市场上同一行业内的不同股票进行投资价值分析是一个系统综合评价问题。本文从评价指标的选择、单项指标的评价、多项指标的综合评价和属性识别准则四部分来阐述属性测度理论在股票投资价值分析中的应用。特别需要指出的是,股票投资价值评价指标体系的建立和指标权重的确定应用了Vague集的理论和方法。最后,我们应用属性综合评价方法对电子元器件制造业的公司股票进行投资价值分析,结果验证了该方法的实用性和正确性。     

类生产函数企业价值链管理模型研究

本文从价值链的一些本质特征出发,借鉴生产函数的原理与形式,提出了一种新的价值链模型——类生产函数价值链管理,证明了类生产函数的一些重要性质,论述了此模型对企业价值链的管理与优化过程。最后进行了实例分析,分析过程及结果表明,该模型能够较好地实现价值链的优化与管理。     

企业信息化指数测算方法研究

应用模糊集合论和主成分分析的方法对企业信息化进行了综合评判,引进了一种新的隶属函数对数据进行了无量纲化处理并确定了各指标权重,建立了山东省企业信息化指数模型。利用此方法对 5家企业信息化进行综合评价,得到了满意的结果。
