ABSTRACT: The processing of waste from confined animal feeding operations (CAFOs) presents a major environmental challenge. Treatment of waste and subsequent land application is a common best management practice (BMP) for these operations in Kentucky, USA, but there are few data assessing the effect of runoff from such operations on aquatic communities. The authors sampled a stream bordering a CAFO with a land application program to determine if runoff from the fertilized fields was adversely affecting stream communities. Water chemistry, periphyton, and macroinvertebrate samples from riffle habitats downstream of the CAFO were compared to samples collected from an upstream site and a control stream in 1999 and 2000. Riffle communities downstream of the fertilized fields had higher chlorophyll a levels than other sites, but there were no significant differences in macroinvertebrate numbers or in biometrics such as taxa richness among the sites. The BMP in place at this site may be effective in reducing this CAFO's impact on the stream; however, similar assessments at other CAFO sites should be done to assess their impacts. Functional measures such as nutrient retention and litter decomposition of streams impacted by CAFOs should also be investigated to ensure that these operations are not adversely affecting stream communities. 相似文献

机场停机坪作业风险管理研究 总被引:1,自引:0,他引:1
停机坪作业具有范围小,保障单位和人员众多等特点,是航空地面事故的多发环节.对停机坪作业存在风险从作业人员、设备和设施、环境、管理等4方面进行识别,然后用AHP定性和定量结合的方法对各风险因素发生的可能性和严重性进行分析,得出各因素风险值,并根据评估结果提出风险控制措施:1)为作业提供良好的人工条件,如良好灯光照明、整齐设备摆放、清晰标识等;2)引进部分设备设施和采用运筹方式合理安排其运行的方式,来解决设备设施数量不能满足需求的问题;3)对于人员执照管理采取定期检查、抽查,定期复训等方式. 相似文献

文化对机组资源管理的影响 总被引:1,自引:0,他引:1
针对国内民航机组资源管理(CRM)及训练中忽视文化的作用和影响的现状,在调研和分析国外CRM与文化影响的基础上,笔者结合国内民航的运行特点,总结、分析了民族文化、组织文化,以及职业文化对机组协作与配合,CRM训练等方面的积极与消极影响,提出中国民航应根据自身的文化特点调整CRM训练的内容和实施方式,并应从3个层面采取措施来提高CRM及其训练的效果,即航空公司CRM训练的设计、实施与评估;飞机制造商在进行驾驶舱人-机界面设计,以及政府部门在对航空器进行适航审定时,应充分识别不同文化的差异、在强化各种文化类型积极影响的同时,努力降低或消除其消极影响。 相似文献

The relationship between military and civilian humanitarian organisations has developed in an increasingly integrative way. Military initiatives to institutionalise the relationship, since the interventions in Somalia and the Balkans, entail a dilution of humanitarian independence as was manifested in practice in Kosovo. Further, the state-centric foundations of military intervention run counter to the potential for humanitarian organisations to foster a cosmopolitan ethos that would not only preserve humanitarian principles but also contest statist assumptions about conflict, development and power. 相似文献

ABSTRACT: Waste waters from various operations at the Miami International Airport are characterized. Servicing, maintenance, overhauling, and washing of aircraft seem to be the most significant waste water producing operations. Pollutional constitutents commonly found in the airport wastes include acids, alkalis, detergents, oil, grease, and oxygen demanding substances. Phenols are of concern when stripping and repainting operations occur. Although most airport wastes may be treatable, a great reduction in influent load can be achieved by proper housekeeping methods. 相似文献

In case of a major incident or disaster, the advance medical rescue command needs to manage several essential tasks simultaneously. These include the rapid deployment of ambulance, police, fire and evacuation services, and their coordinated activity, as well as triage and emergency medical care on site. The structure of such a medical rescue command is crucial for the successful outcome of medical evacuation at major incidents. However, little data has been published on the nature and structure of the command itself. This study presents a flexible approach to command structure, with two command heads: one emergency physician and one experienced paramedic. This approach is especially suitable for Switzerland, whose federal system allows for different structures in each canton. This article examines the development of these structures and their efficiency, adaptability and limitations with respect to major incident response in the French‐speaking part of the country. 相似文献

生产作业区重大危险源评估方法研究 总被引:1,自引:0,他引:1
吴岩 《中国安全生产科学技术》2012,8(3):158-164
危险源是危险的根源,是系统中存在的可能发生意外释放能量的危险物质,开展重大危险源评估工作可有效预防和控制生产作业区重大安全事故的发生,保障人民群众生命财产安全,同时也为生产作业区安全监督管理提供依据。以某生产作业区为例,研究了生产作业区重大危险源辨识标准及分类分级方法,研究了重大危险源安全现状及危害等级的安全评估方法,指出了企业在重大危险源安全管理上应采取的安全技术措施和安全管理措施,为提高生产作业区安全管理水平,制定重大危险源专项应急预案提供了依据,上述辨识和评估思路和方法可为其他企业借鉴参考。 相似文献

Organizations are increasingly engaging in socially and environmentally sustainable initiatives. This paper focuses on the institutional isomorphism mechanisms to analyse the organizational adoption of sustainable manufacturing practices like eco-design, source reduction, and environmental management practices. This paper empirically examines the role of institutional influence in the organizational adoption of sustainable manufacturing practices among firms in India. The results of this study confirm the significance of the three institutional isomorphism mechanisms in influencing sustainable responses, but not all mechanisms influence the organizational response equally. In particular, the results show a strong influence of self-regulatory normative isomorphism on the implementation. 相似文献

Cotton textile manufacturing operations cause air pollution. Air pollutants are generated by fossil fuel fired combustors due to their flues and/or a variety of chemicals in use for production. Excessive use of chemicals can be stopped or minimized by replacing them or by optimizing the production processes. Energy and water conservation are important goals in textile workplaces as well. There is substantial research and development to minimize pollution potentials of textile operations. In this paper air polluting potentials of cotton textile manufacturing operations are discussed and some quantitative examples are given for evaluating the risks to the environment. Studied impacts to environment cover direct discharges into the ambient air as well as the workplace atmosphere. Further studies are recommended for minimizing the impacts to the local and global air quality due to cotton textile production facilities. 相似文献

A major area of investment in data collection in developing countries has been that of nutritional surveillance and monitoring. From recent debate it is clear that there is currently no consensus on the potential role of nutritional status as an early warning indicator. The author presents a synthesis of the broad spectrum of views on the role nutritional surveillance could or should have in early warning. Conceptual problems and technical difficulties are reviewed in the light of recent experiences in Africa and Asia. The author raises a number of issues for future discussion in this ongoing debate. 相似文献
