化工储罐区安全评价探讨

改革开放以来,随着我国国民经济的快速发展,化工产品的需求也在不断增多,从而促进了化工产业的快速发展。在化工企业进行生产的过程中,化工储罐区经常用于贮存易燃、易爆、有毒等化学原料。如果化学储罐区管理手段不完善就会容易引起有毒物质以及火灾等等安全生产事故。因此,加强化工储罐区安全评估,对于降低事故发生率,实现安全生产具有十分重要的意义。     

成品油销售企业如何有效地推进HSE管理体系

成品油具有明显的易燃、易爆、易挥发、易扩散、有毒、腐蚀性等特征,这些特征决定了石油石化行业的高风险性。近年来,随着政府监管力度的加大,以及企业安全管理力度的不断加大,终端销售企业发生重大伤亡事故和环境污染事故的频次相对于上游企业较少,而一旦造成事故,事故影响却比上游企业大得多。文章主要研究成品油销售企业如何有效地推进HSE管理体系。     

便秘可诱发老年痴呆

<正>国外老年病研究机构发现,人体肠道内的细菌会将没有被消化的蛋白质分解成氨、硫醇、吲哚、硫化氢和组织胺等有毒物质,一般情况下,这些有毒物质可通过大便排出体外。但老年人肠道功能减退,特别是老年便秘患者很难正常排除这些有毒物质,久而久之就会大量积累有毒物质,当有毒物质积累到一定程度时,就会随着血液循环慢慢进入大脑,损害

美国将筑化学品管理新壁垒 机电纺织企业面临又一波“绿考”

继欧盟化学品新规REACH之后,中国产品出口又将面临新一波“绿色考验”。据悉,美国有关改进有毒物质控制法案（TSCA）的听证会有望在明年春天召开,修改后意味着世界上最早的化学品名录制度——“有毒物质控制法”将被新的化学品管理制度所取代。美国此番对已有三十年历史的有毒物质控制法案进行修改,别有深意,相关企业须密切跟踪并关注。

Exploring the relationship between technology diffusion and new material diffusion: the example of advanced ceramic powders

New technologies have been recognized as key drivers for corporate profitability and growth in today's fast changing environments, especially in new materials field. However, little has been done in discussing the technology diffusion on the topic of new materials. In this study, we investigate the diffusion of advanced ceramic powders technology using patent citation data. We also adopt the sales data of the advanced ceramic powders for measuring the new material diffusion. At last we analyze the relationship between “technology diffusion” and “material diffusion” through the Bass diffusion model. The results show that the diffusion of technology through patent citation could be successfully explained by empirical analysis for which the Bass diffusion model was adopted. Furthermore, we can find out if technology diffusion can be the leading indicator of a new material's diffusion before its launching which is before the commercialization of the patent.

Hyperlinked actors in the global knowledge communities and diffusion of innovation tools in nascent industrial field

Innovation is accomplished through collaborations of thousands of researchers embedded in a growing international knowledge community, where some hyperlinked actors can strongly impact the diffusion of innovation tools within the community. Few extant studies have empirically inspected the following issues which govern the influence of hyperlinked actors: (1) how the heterogeneity in their actor attributes regulates the volume of their influences; (2) how the nature of connectivity of these actors impacts the volume of their influences. Our current study intends to address this gap by examining the diffusion of innovation tools among life scientists around the world in a time span of 16 years, and we find that for hyperlinked scientists: (1) heavy usage and high variety of usage behaviors have stronger relationship with diffusion rate than light usage and low variety of usage; (2) light usage and high variety usage behaviors have stronger relationship with extent of diffusion than heavy usage and low variety usage; (3) international links have stronger relationship with both the rate and extent of diffusion than domestic links. Our work contributes to innovation research by providing a sharper understanding on the social contagion mechanism in innovation diffusion within global knowledge communities.     

Templates for financial control? Management and employees under the private equity business model

The term ‘private equity business model’ (PEBM) refers to private equity investors that delist publicly quoted firms, managing them as private equity‐controlled portfolio firms. But how and in what form do these investors diffuse a preferred template for the PEBM in portfolio firms? Is diffusion codified, institutionalised or merely tacit? What is the difference between these forms of diffusion? As a method of financial control, how is diffusion evident for managers and workers? Theoretically, while ‘financialisation’ is a contemporary pressure on the British economy, there is a ‘disconnection’ between competitive pressures for financialisation and the diffusion of practices to manage these pressures in portfolio firms. Forty‐two interviews in eight portfolio firms and five associated private equity firms concludes that potentially transformative and decisive restructuring for managers and workers is more evident than a defined template.     

Genetic distance,trade, and the diffusion of development

The determinants of countries' long‐term income differences feature prominently in the literature. Spolaore and Wacziarg (The diffusion of development, Quarterly Journal of Economics, 2009 , 124, 469–529) argue that cultural differences, measured by countries' genetic distance, are an important barrier to the diffusion of development from the world's technological frontier. We revisit their findings in three ways. First, we successfully reproduce their results and confirm the robustness of their baseline findings. Second, we estimate their models for different time periods and find that the impact of genetic distance on income differences did not significantly change over time. Finally, we explore one of the underlying mechanisms of technology adoption and show that bilateral trade is one channel through which cultural differences retard the diffusion of development.     

XBRL扩散的影响因素及对策研究

XBRL扩散在降低监管成本、加强投资者利益保护和推动会计准则国际趋同方面发挥着重要作用。由于起步较晚、基础研究滞后、分类标准体系不完善、应用软件开发和认知不足等原因导致XBRL技术在我国的采纳扩散受到了影响。汲取国外经验、不断完善分类标准、构建综合信息交换平台、开发我国自己的应用工具集对促进XBRL在我国的扩散具有积极促进作用。

Multinationals,labour management and the process of reverse diffusion: A case study

This paper investigates a form of diffusion largely overlooked in the literature, namely reverse diffusion, in which practices flow from the overseas to the domestic plants. It examines the process of this type of diffusion, focussing on the role of the HQ and the way in which plant managers are influenced by management at this level. Evidence is presented from a case study of a British MNC.

Analysing the factors influencing clean technology adoption: a study of the Spanish pulp and paper industry

Technological change has a relevant role to play in the transition towards a sustainable industry. However, slow diffusion of clean technologies can be observed in OECD countries. The analysis of the determinants and barriers to clean technology adoption should be a main goal of economists and social scientists. This paper shows that three sets of interrelated factors prevent but also stimulate the widespread adoption and diffusion of clean technology: these are factors external and internal to the firm, conditions of the potential adopters and characteristics of the environmental technology. These factors are included in the so‐called ‘triangular model’, which is further applied to the analysis of clean technology adoption in the pulp and paper industry in Spain. The empirical study shows that clean technology adoption decisions are the result of an interaction between these factors, often involving contradictory signals for the potential adopter. The paper closes with some public policy recommendations for the effective and efficient promotion of clean technology diffusion. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.
