关于电器产品电气安全性能在线检测及远程监管系统的研究

为解决出口电器产品电气安全问题,政府部门检验职能逐步转向对整个生产环节进行监管。通过在线检测及远程监管系统的建立,对企业综合信息、产品质量信息、外贸申报信息、政府监管信息等产业链信息进行管理和验证,实现了抽批检验、验证检验、过程检验、型式试验、质量体系监督管理、质量事故追溯等,对产品信息源的真实性、准确性实施有效监控,突破了政府部门传统检验监管发展的瓶颈,在保证监管有效性的同时降低了成本提高了效率。     

高职院校环境监察专业教学改革研究

《社交心理学》公共选修课教学实效性的思考

结合中国环境管理干部学院《社交心理学》选修课教学过程中,部分学生对选修课的意义认识不清而导致的随意或从众选课、上课过程中应付或逃课等实际情况,从教学管理、授课内容、教学方法、考核方式等环节,提出了增强公共选修课的实用性和趣味性的建议与对策。     

安全工程专业部分课程内容的划分

鉴于国内安全工程专业教材内容、教学内容交叉严重的现状及其导致的教学组织困难等问题,笔者根据安全教育实践、安全管理实务的需要以及国内外的安全科学研究进展,对安全系统工程、安全评价、安全管理学、安全学原理、安全经济学、风险管理、安全法律法规等目前各高等学校安全工程专业普遍开设的专业课程的内容进行了划分.该划分的见解,可供国内安全工程专业的专业课程教学组织以及教学改革作为参考.     

创新教育在安全工程专业实验课教学中的探讨与实施

基于中美10所高校的应急管理核心知识体系的解释结构模型研究

应急管理涉及多学科、多领域,明确其核心知识体系可以为应急管理相关学科融合和发展提供基础。本文收集了中美两国10所高校15个本科专业225门专业课程,构建解释结构模型进行研究。结果显示：应急管理核心知识体系包括8大类：应急类、防灾减灾类、公共服务和社会管理类、安全生产类、国家安全类、法律类、公共卫生类和综合类。这8大类又分为18个小类,应急类包括为理论、技术方法和应用;防灾减灾类包括理论、过程和单灾种防范;公共服务和社会管理类包括理论与应用;安全生产类包括安全、健康和环境;国家安全类包括国土安全、恐怖主义和国际关系;公共卫生类包括心理和医疗救助;而法律类重在应急相关法律,综合类则表现为多个领域相结合。该体系的构建可以为应急管理相关学科研究提供知识基础,促进各学科领域在应急研究方面融合发展。     

A SURVEY OF HYDROLOGY COURSE CONTENT IN NORTH AMERICAN UNIVERSITIES1

ABSTRACT: This report presents the results of a survey of hydrology faculties of colleges and universities in the United States and Canada. Information is presented on topics covered in classes, allocation of class periods to individual topics, textbooks, prerequisites, computer use, and accreditation categories for hydrology courses offered by engineering departments. Hydrology courses generally require courses in fluid mechanics, mathematics, statistics, and computer science as prerequisites. Topics that receive the largest allocation of time in both introductory and advanced courses include rainfall-runoff relations, the hydrologic cycle, routing and open channel flow, and statistics. Advanced courses place greater emphasis on watershed models than do the introductory courses. Hydrology courses at both levels allocate the smallest amounts of time to snow hydrology ground-water hydrology, and “other topics.” Very few courses include field or experimental work. In a discipline where computer modeling is a major tool, this lack of field and data-collection experience may lead students to underestimate the uncertainties associated with data used to calibrate models and the modeling results themselves. Survey responses on hydrology courses taught in departments other than civil engineering were too few to permit detailed analysis. Most of these courses spend approximately two-thirds of available class time on the same topics as presented in engineering hydrology courses. The balance of class time is spent on topics that emphasize the specialized interest of the particular discipline, such as soil physics and soil moisture in agricultural engineering.     

外来入侵物种空心莲子草光合日变化初步研究

外来入侵物种空心莲子草(Alternanthera philoxeroides)发生广、危害重的区域多为中国南方省市,2005年发现其已大面积入侵山东省济南市境内的小清河上游.测定了空心莲子草净光合速率、气孔导度和细胞间隙CO2浓度,并与同一生境的芦苇(Phragmites communis)和水芹(Oenanthe javanica)进行了比较.空心莲子草净光合速率日变化曲线为双峰型,最高峰值24.40μmol CO2/(m2·s)出现在10:00左右,第二峰值22.80 μmol CO2/(m2·s)出现在16:00左右,整个曲线明显高于对照植物芦苇和水芹.在16:00至16:30光强迅速下降阶段.其净光合速率仍能保持较高水平,为9.85 μmol CO2/(m2·s).     

Subhabitat selection by foraging threespine stickleback (<Emphasis Type="Italic">Gasterosteus aculeatus</Emphasis>): previous experience and social conformity

Any mechanism that allows animals to increase their foraging efficiency is likely to be selected for, including the ability to learn to recognise and subsequently discriminate between habitat types based on their profitability. In a series of laboratory studies, we manipulated prey densities across two different experimental subhabitats and demonstrated that threespine stickleback (Gasterosteus aculeatus) can develop foraging preferences for subhabitats that have previously yielded prey. Fish were not recalling the spatial location of prey patches; rather, they were discriminating between subhabitats based on foraging experience there and allocating foraging effort accordingly. Foraging preferences took around 14 days to develop, and once established, they persisted independently of experimental prey density, suggesting that fish were using experience rather than real-time sampling to select foraging grounds. When we presented focal fish with social information cues, we found that they preferentially used local enhancement and current public information cues when they conflicted with previous experience, but that they did not use prior public information. This suggests that in the presence of conspecifics, individuals prioritise social conformity over the use of private information. We discuss our results in the context of optimal foraging and the trade-offs associated with balancing conflicting private and social information.     

企业资源战略整合与可持续发展

企业的发展是与企业对资源的战略性整合密切相关的。由于企业所处的行业不同 ,行业特性所表现的资源特征也不尽相同。但是 ,就同处于一个行业内的企业来讲 ,其资源的基本构成是相同的。然而 ,这些资源的最终表现形态和结果却有很大的差异 ,因此 ,出现了有的企业兴旺发达 ,有的企业衰落而倒闭。所以 ,研究企业的资源整合对企业的可持续发展有着重要的现实意义
