企业安全资源的资源观分析

依据资源理论对资源优势与竞争优势之间关系的研究成果,笔者提出安全资源优势是企业形成整体资源优势的必备条件之一,良好的安全资源能够为企业创造竞争优势。为此,首先指出,企业的安全意识、安全制度与安全设施等均属企业中的安全资源之列,按照资源理论对企业资源的分类,该类安全资源贯穿于企业的各种资源之中;随后,论述了安全资源与企业中的其他资源一样,具有价值性、稀缺性、不可模仿性和不可替代性等优势资源禀赋;根据资源理论中对竞争优势的经济学解释,分析了安全资源本身,以及安全资源与企业中其他资源的组合使用是如何为企业创造竞争优势的,安全资源优势通过降低企业的长期平均生产成本、延长其他资源的使用寿命从而提高产品产量等途径,能够为企业创造租金,进而形成企业的竞争优势。该论述以全新视角认识企业安全资源,有助于企业改变以往对安全资源建设的错误认识,调动企业对安全资源投资的积极性和主动性     

Long-Term Observation of Asian Dust in Changchun and Kagoshima

Monitoring of Asian dust at two stations in Changchun, Jilin Province in northeast China, and Kagoshima, southwest Japan, is discussed. In Changchun, interval records were made with digital and video cameras from 18 March 2003. In Kagoshima, a web camera system to monitor volcanic clouds has been working since December 2000, which also provides data for studies of dust. A heavy dust episode on 11 November 2002, affecting both stations, was detected using 11 and 12 μm channels of NOAA/AVHRR. We observed dust in Changchun on 26 March, 7, 14–16 April, 1–2, 8, 10, 19 May, 8, 23 June, and 12 July in 2003. The observed images corresponded well to NOAA/AVHRR imagery and with 8.6, 11 and 12 μm Terra/MODIS results, although conditions were too cloudy for satellite verification in some cases.     

The use of virtual environments for percentage view analysis

It is recognised that Visual Impact Assessment (VIA), unlike many other aspects of Environmental Impact Assessments (EIA), relies less upon measurement than upon experience and judgement. Hence, it is necessary for a more structured and consistent approach towards VIA, reducing the amount of bias and subjectivity. For proposed developments, there are very few quantitative techniques for the evaluation of visibility, and these existing methods can be highly inaccurate and time consuming. Percentage view changes are one of the few quantitative techniques, and the use of computer technology can reduce the inaccuracy and the time spent evaluating the visibility of either existing or proposed developments. For over 10 years, research work undertaken by the authors at the University of Nottingham has employed Computer Graphics (CG) and Virtual Reality (VR) in civilian and industrial contexts for environmental planning, design visualisation, accident reconstruction, risk analysis, data visualisation and training simulators. This paper describes a method to quantitatively assess the visual impact of proposed developments on the landscape using CG techniques. This method allows the determination of accurate percentage view changes with the use of a computer-generated model of the environment and the application of specialist software that has been developed at the University of Nottingham. The principles are easy to understand and therefore planners, authorisation agencies and members of the public can use and understand the results. A case study is shown to demonstrate the application and the capabilities of the technology.     

牢固树立科学发展观全面推进环境保护工作

随着环境保护工作地位的进一步提升,环境保护工作取得了长足的进展,但是环境功能问题依然很严峻,因此,要牢固树立科学发展观,积极探索循环经济之路,推进生态省建设、打造良好的人居环境,同时也要抓好重点城市的综合治理,加快基础能力建设,进而形成经济、社会、环境同步发展的新局面.

Crisis management of SARS in a hospital

INTRODUCTION: A large general hospital was suddenly disabled by an in-hospital outbreak of Severe Acute Respiratory Distress Syndrome (SARS). METHOD: The crisis was successfully managed by a Standard Operation Procedure (SOP) that included: (a) containment of SARS patients on a special floor and evacuation of the patients from the infected and near-around floors; (b) sorting of the hospital into areas and floors to avoid cross contact of people; (c) triage of patients into groups according to risks; (d) closure of the emergency room and outpatient clinics; and (e) set up of an outdoor fever screening station and emergency service. RESULTS: The situation was quickly controlled after the implementation of these procedures. The central argument in this case is that crisis managerial behavior is the result of how managers channel and distribute the attention of their crisis sense. IMPACT ON INDUSTRY: What managers should do depends on what risk issues and actions related to risk independency, efficiency, safety priority, and transparency they take. What risk issues and actions they take depends on the crisis sense and on how management responds to leadership, resource, and execution.     

Comparing results of cultured and uncultured biological methods used in biological phosphorus removal

Increasing attention has been paid to phosphate-accumulating organisms(PAOs)for their important role in biological phosphorus removal.In this study,microbial communities of PAOs cultivated under different carbon sources(sewage,glucose,and sodium acetate) were investigated and compared through culture-dependent and culture-independent methods,respectively.The results obtained using denaturing gradient gel electrophoresis(DGGE)of polymerase chain reaction-amplified 16S rDNA fragments revealed that the diversity of bacteria in a sewage-fed reactor(1#)was much higher than in a glucose-fed one(2#)and a sodium acetate-fed one(3#);there were common PAOs in three reactors fed by different carbon sources.Five strains were separated from three systems by using a phosphate- rich medium;they were from common bacteria isolated and three isolates could not be found in DGGE profile at all.Two isolates had good phosphorus removal ability.When the microbial diversity was studied,the molecular biological method was better than the culture-dependent one.When phosphorus removal characteristics were investigated,culture-dependent approach was more effective. Thus a combination of two methods is necessary to have a comprehensive view of PAOs.
