微生物传感器快速测定水中BOD

采用220B型BOD快速测定仪,对标准样品、地表水、生活污水、工业废水中的BOD进行测定,与五日生化培养法进行了比对分析.结果表明：该方法检出限为0.032mg/L;加标回收率在85%～117%之间;相对误差＜6%,相对标准差＜9%,有较高的精密度、准确度;测定地表水、生活污水与五日生化培养法有较好的可比性,测定工业废水存在一定的局限.同时还阐述了微生物传感器快速测定法测定BOD与五日生化培养法,并对其优缺点做了分析比较.     

民族旅游开发与民族文化保护理念

"We all knew that a cyclone was coming": disaster preparedness and the cyclone of 1999 in Orissa, India

Imagine that a cyclone is coming, but that those living in the affected areas do nothing or too little to protect themselves. This is precisely what happened in the coastal state of Orissa, India. Individuals and communities living in regions where natural hazards are a part of daily life develop strategies to cope with and adapt to the impacts of extreme events. In October 1999, a cyclone killed 10,000 people according to government statistics, however, the unofficial death toll is much higher. This article examines why such a large loss of life occurred and looks at measures taken since then to initiate comprehensive disaster-preparedness programmes and to construct more cyclone shelters. The role of both governmental organisations and NGOs in this is critically analysed. The good news is that, based on an assessment of disaster preparedness during a small cyclone in November 2002, it can be seen that at community-level awareness was high and that many of the lessons learnt in 1999 were put into practice. Less positive, however, is the finding that at the state level collaboration continues to be problematic.     

试论长江文化生态的主要特征

大自然孕育了万物,人类又在自然的基础上创造了文化。久远深厚、异彩纷呈的长江文化,正是得益于广阔的发展舞台、优越的生态环境条件。因此探讨长江文化系统与生态环境系统的耦合关系－文化生态,就具有十分重要的意义。着重论述了长江文化生态的主要特征：（1）整体性－－长江文化生态系统的各组成部分是彼此联系、相互作用的统一,它能反映整体的特征和活动方式,它孕育了长江多元文化。（2）开放性－－长江流域是一个庞大的、开放的外流水网系统,该系统不从外部输入物质、能量和信息,吸收并累积负熵流,维持其有序性。长江文化具有悠久的开放传统和宽广的心态。（3）动态性－长江文化生态系统的动态特征,既有周期性变化也有非周期性变化。（4）人地相关性－长江文化生态民是人地关系相互作用的统一体,回顾长江文化的发展史,人与自然关系经历了“强烈依赖－－被动顺序－－主动征服－－相互和谐”几个阶段。

The relationship between employees' perceptions of safety and organizational culture

PROBLEM: With limited resources to help reduce occupational injuries, companies struggle with how to best focus these resources to achieve the greatest reduction in injuries for the optimal cost. Safety culture has been identified as a critical factor that sets the tone for importance of safety within an organization. METHOD: An employee safety perception survey was conducted, and injury data were collected over a 45-month period from a large ready-mix concrete producer located in the southwest region of the United States. RESULTS: The results of this preliminary study suggest that the reductions in injuries experienced at the company locations was strongly impacted by the positive employee perceptions on several key factors. Management's commitment to safety was the factor with the greatest positive perception by employees taking the survey. DISCUSSION: This study was set up as a pilot project and did not unitize an experimental design. That weakness reduces the strength of these findings but adds to the importance of expanding the pilot project with an appropriate experimental design. SUMMARY: Management leadership has been identified, along with several other factors, to influence employee perceptions of the safety management system. Those perceptions, in turn, appear to influence employee decisions that relate to at-risk behaviors and decisions on the job. IMPACT ON INDUSTRY: The results suggest that employee perceptions of the safety system are related to management's commitment to safety, which, in turn, appear to be related to injury rates. Management should focus on how to best leverage these key factors to more positively impact injury rates within their companies.     

Disaster mitigation and preparedness on the Nicaraguan post-Mitch agenda

Nicaragua provides an example of how a major disaster, in this case Hurricane Mitch, can transform the national agenda for disaster mitigation and preparedness. Hurricane Mitch was a reminder of how extremely disaster prone Nicaragua is, and also how neoliberal reforms have weakened governmental response capacity. In the face of critiques of how governmental policies had affected preparedness and response, discussions of this transformation became a highly politicised process where the debate over alternative development models tended to overshadow the original calls to strengthen risk management. Progress can be seen in some areas, such as disaster mitigation through environmental management. This study of NGO roles, and their relations with other key actors, draws attention to the need to anchor improved risk management in local-level NGO-government collaboration. Structures are being put into place to achieve this aim, but dependence on donor financing raises questions regarding the longer-term sustainability of these efforts.
