大学生减灾教育对策研究

灾害风险认知能力是进行减灾教育的基础,受众获取灾害知识与信息的方式是影响减灾教育方法的重要因素,而受众获取灾害知识与信息的途径则会直接影响灾害内容的传递效率和效果。本文针对以上所关心的问题,为了建立合理有效的大学生减灾教育计划,应对大学生防灾减灾意识和能力不足的现状,通过问卷调查,分析和研究了来自不同生源地大学生的灾害风险认知水平、获取灾害知识和信息的方式与途径。从自然灾害风险认知的视角,通过寻找不同特性大学生群体获取减灾知识与信息的差异和趋同性,提出了现势条件下针对大学生的减灾教育对策。

Sustainable outsourcing: a practice survey and research opportunities

This paper addresses the issue of the sustainability imperative and its influence on outsourcing practice. The research initially finds that there is currently little or no work that explores sustainable or green outsourcing, other than in an information technology context. This lack of research on sustainable outsourcing practice in the industrial organisation sector led to the development of this research study. This exploratory study used a qualitative survey tool to investigate current industrial practice. Manufacturing managers in 57 organisations formed the survey sample. The data were analysed by comparison and clustering of responses of survey participants. This study contributes five key findings that demonstrate current industrial practice which includes: 32% of respondents state that sustainability is not a factor in their outsourcing decision making and 65% of small- and medium-sized enterprises had never heard of the ‘triple bottom line’ concept. Future research needs are identified and proposed highlighting that urgent development of research is required in outsourcing performance measurement and also in considering sustainability as a new manufacturing competitive priority.     

纸片法快速测定水质总大肠菌群

简要介绍了纸片法测定水质总大肠菌群的操作方法，并通过６个实验室的验证试验，研究了纸片法与现行标准方法（多管法）的一致性。结果表明，２种方法的测定结果基本一致，无显著性差异，但纸片法测定周期比多管法缩短了２ｄ，仅需１ｄ即可。     

高职院校环境专业就业情况调查——以中国环境管理干部学院2014届毕业生为例

采用资料收集、实地调研、调查问卷等方法,对环境保护领域人才需求情况以及岗位知识技能的要求、环境专业毕业生的就业意向进行调查和分析。结果表明,企业对高职环保人才需求量较大,环保人员应具备的素质以分析问题能力和沟通能力为主;高职院校环境专业毕业生对目前环境保护行业就业形势认识清楚,对就业单位的环保人才素质需求分析正确,但求职过程中存在目标设定偏高等问题,因此,从课程设置、教学方法和就业指导方面提出措施。     

A field experiment characterizing variable detection rates during plant surveys

Surveys aimed at finding threatened and invasive species can be challenging due to individual rarity and low and variable individual detection rates. Detection rate in plant surveys typically varies due to differences among observers, among the individual plants being surveyed (targets), and across background environments. Interactions among these 3 components may occur but are rarely estimated due to limited replication and control during data collection. We conducted an experiment to investigate sources of variation in detection of 2 Pilosella species that are invasive and sparsely distributed in the Alpine National Park, Australia. These species are superficially similar in appearance to other yellow-flowered plants occurring in this landscape. We controlled the presence and color of flowers on target Pilosella plants and controlled their placement in plots, which were selected for their variation in cover of non-target yellow flowers and dominant vegetation type. Observers mimicked Pilosella surveys in the plots and reported 1 categorical and 4 quantitative indicators of their survey experience level. We applied survival analysis to detection data to model the influence of both controlled and uncontrolled variables on detection rate. Orange- and yellow-flowering Pilosella in grass- and heath-dominated vegetation were detected at a higher rate than nonflowering Pilosella. However, this detection gain diminished as the cover of other co-occurring yellow-flowering species increased. Recent experience with Pilosella surveys improved detection rate. Detection experiments are a direct and accessible means of understanding detection processes and interpreting survey data for threatened and invasive species. Our detection findings have been used for survey planning and can inform progress toward eradication. Interaction of target and background characteristics determined detection rate, which enhanced predictions in the Pilosella eradication program and demonstrated the difficulty of transferring detection findings into untested environments.     

我国公众环境保护意识的调查与分析

本文根据一次大规模的抽样调查资料，初步分析了我国公众环境保护意识的现状，认为从总体上看，公众的环保意识水平偏低；公众的环境资源况颇具特色；在经济发展与环境保护之间出现明显矛盾时，半数公众能够优先考虑环境保护；大多数公众认为环境保护与个人有关，但对个人的努力信心不足；超过七成的公众表示愿意为环境保护支付一定费用，但对高收入阶层普遍寄予较高的期望；公众有一定的依法保护环境的心理基础，但法律知识又非常缺乏。     

企业采用自愿协议式环境管理方法的意愿调查

“企业采用自愿协议式环境管理方法的意愿调查”是欧盟资助项目“自愿协议式环境管理方法在中国工业环境管理中应用的可行性研究”的主要成果之一。调查结果表明，自愿协议式环境管理方法目前在中国只是处于初步的认知阶段，但大多数企业愿意尝试采用自愿协议式方法解决环境问题，积极性较高，且谈判式自愿协议被看好。     

Pleasure in using adaptive cruise control: A questionnaire study in The Netherlands

Objective: Adaptive cruise control (ACC), a technology that allows for automated car following, is becoming increasingly prevalent. Previous surveys have shown that drivers generally regard ACC as pleasant but that they have to intervene when the ACC reaches its operational limits. The former research has been mostly concerned with specific car brands and does not fully reflect the diversity of ACC types in traffic today. The objective of the present research was to establish the determinants of pleasure in using ACC.

Methods: A 55-item online questionnaire was completed by Dutch users of diverse ACC systems.

Results: Respondents (N = 182) rated their ACC highly, with a mean score of 8.0 on a scale from 1 (extraordinarily negative) to 10 (extraordinarily positive) and were most pleased with ACC on high-speed roads and in low-density traffic. Moreover, the findings point to specific operational limits such as associated with cut-in situations. Pleasure was greater for the types of ACC that are able to decelerate to a full stop, according to 48% of our sample. An analysis of the free-response items indicated that respondents who were displeased with ACC mentioned its occasional clumsiness and the dangerous situations it may evoke, whereas those who were pleased with ACC valued the complementarity of human and machine and emphasized the roles of responsibility and experience in using ACC.

Conclusion: Pleasure in using ACC is a function of both technological advances and human factors.
