Policy context as a factor of bias in the valuation of environmental goods – a dual-process theories perspective

When ecosystem services value estimates are applied in the economic assessment of environmental policies, high accuracy of these estimates is required. One of the directions in the scientific discussion on biases in stated preference (SP) valuation surveys builds on dual-process theories of judgment. The paper contributes to this literature by presenting an experiment where two types of judgment were induced via separate versus joint valuation of environmental goods. The results demonstrated that policy relevance of environmental issues, e.g. the need for conservation measures increases emotional response, causing a larger bias in the separate design as it involves ‘valuation by feeling.’ This finding suggests that the context of a specific policy, which is often the reason for conducting SP surveys, influences the answers, thereby making the results less reliable for use in cost–benefit analysis.     

A systematic review of animal personality in conservation science

Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer-reviewed literature relating to conservation science and animal personality. Criteria for inclusion in our review included access to full text, primary research articles, and relevant animal conservation or personality focus (i.e., not human personality studies). Ninety-two articles met these criteria. We summarized the conservation contexts, testing procedures (including species and sample size), analytical approach, claimed personality traits (activity, aggression, boldness, exploration, and sociability), and each report's key findings and conservation-focused suggestions. Although providing evidence for repeatability in behavior is crucial for personality studies, repeatability quantification was implemented in only half of the reports. Nonetheless, each of the 5 personality traits were investigated to some extent in a range of conservations contexts. The most robust studies in the field showed variance in how personality relates to other ecologically important variables across species and contexts. Moreover, many studies were first attempts at using personality for conservation purposes in a given study system. Overall, it appears personality is not yet a fully realized tool for conservation. To apply personality research to conservation problems, we suggest researchers think about where individual differences in behavior may affect conservation outcomes in their system, assess where there are opportunities for repeated measures, and follow the most current methodological guides on quantifying personality.     

Comparative analysis of two tobacco surveillance questionnaires used in NHANES: accuracy of self-reported smoking status

National Health and Nutrition Examination Survey (NHANES) uses two tobacco use surveillance questionnaires. One is administered during an at-home interview (HI) and the other, during an examination session at a mobile examination center (MEC). NHANES data for the years 1999–2012 were used to evaluate the consistency of responses to tobacco surveillance questions in HI and MEC interview. In addition, accuracy of self-reported smoking status was evaluated. Of those who reported to be daily cigarette smokers during HI, 18.7% reported to be either some-day smokers or nonsmokers during MEC interview. Of those who reported to be some-day cigarette smokers during HI, 22.1% reported to be daily smokers and 17.5% reported to be nonsmokers. Also, 4.1% of those who reported to be nonsmokers during HI reported to be either daily or some-day smokers during MEC interview. Using serum cotinine measurements taken during MEC interview, 27.1% were found to be smokers and 72.9% were found to be nonsmokers. In general, a moderate to high agreement, as measured by the κ statistic, was found between the self-reported responses to tobacco use questions during the home and MEC interviews as well as between smoking statuses based on self-reported and serum cotinine measurements.

2种除草剂联合胁迫下日本青鳉的逐级行为响应(The Stepwise Behavioral Responses of the Japanese Medaka under the Joint Stress of Two Herbicides)

探讨了日本青鳉在两种除草剂阿特拉津和百草枯联合暴露下的逐级行为响应,采用水质安全在线生物预警系统(BEWs)记录行为强度数据,分析不同暴露浓度、不同暴露时间日本青鳉的行为响应.10、5、1和0.1TU的暴露浓度下行为反应时间分别为:0.74、7.7、29.4和42.2h,而每个浓度不同配比之间行为反应时间差异明显.结果表明:在两种除草剂的暴露下,日本青鳉的逐级行为响应既受化合物浓度高低的影响,又受暴露时间的影响,而且每个浓度两种药物不同配比暴露下的青鳉鱼的逐级行为响应基本一致,每个浓度不同配比之间行为反应时间差异明显,即两种作用机制不同的除草剂对日本青鳉的行为毒性是协同作用.     

低剂量双酚A影响哺乳动物神经发育研究现状及争议

为全面认识低剂量BPA（双酚A）对哺乳动物神经发育的影响,本文从中国知网、PubMed和Web of Science 3个数据库中获取了国内外关于低剂量BPA影响哺乳动物神经发育的研究报道,并使用toxR工具对其可信度进行评估,最终筛选获得26项相关研究;从美国食品药品监督管理局（FDA）工作网站上获取最新BPA毒性报告1篇.通过比较分析这些研究,发现大部分研究报道低剂量BPA暴露导致哺乳动物神经行为、特定脑区内组织学结构和细胞特征、神经递质和激素稳态、脑中关键基因表达以及表观遗传特征发生改变.但是,就导致的神经行为的改变而言,一些研究的结果并不一致甚至有诸多矛盾之处.这些不一致的结果可能与动物实验设计的差异有关,其中神经行为测试的质量控制和统计方法中统计单元的选择对于研究结果的影响尤其值得关注.总之,从目前的文献来看,低剂量BPA对哺乳动物神经发育的影响尚待进一步的确认.     

心理学视角下事故致因与行为探究综述

为了从人的心理角度解释事故发生的原因,研究消除和预防事故的根本措施,以行为心理学理论为指导去研究实践活动中涉及人的行为规律和特点,开展人的行为模式研究。在分析安全视角下人的主要心理因素及心理效应的基础上,分析了人的不安全行为与心理特征之间的关系,建立了心理因素下不安全行为形成模式,继而用心理学效应诠释了事故致因,提出了事故发生的内在心理机制。从人内在心理角度去理解和研究事故预防是安全科学研究的必然趋势,心理探究能为事故致因分析和人的不安全行为心理研究提供一种新的思路和方法。     

Are sociodemographic characteristics and attitude good predictors of speeding behavior among drivers on Malaysia federal roads?

Objective: The increasing number of road crashes and fatalities on Malaysian federal roads is a cause for concern. The main causes of road crashes and fatalities on federal roads have been attributed to the speeding behavior among drivers. As such, this research investigates the possible predictors from sociodemographic characteristics and attitudes in predicting speeding behavior among drivers on Malaysia federal roads.

Methods: A face-to-face survey was conducted via purposive sampling on 300 drivers at rest areas at 6 crash hotspots on Malaysian federal roads. A set of questions related to speeding behavior was developed. The questionnaire consisted of 10 questions related to sociodemographic characteristics of the participants, 37 questions regarding attitudes toward speeding, and 1 question regarding speeding behavior. Subsequently, the sociodemographics were analyzed using binary logistic regression and the attitude variable was analyzed using factor analysis and binary logistic regression.

Results: The findings from the sociodemographic data revealed that male gender, single/separated status, broad driving experience, crash experience, and leisure/vacation trip purposes emerged as significant predictors for speeding behavior. Additionally, the results of factor analysis for the attitude variable revealed 3 components: Affective, behavioral, and cognitive. These 3 components are originally derived from the ABC model of attitude (affective, behavioral, and cognitive) that was adapted in this study. Furthermore, the findings from binary logistic regression appeared consistent with the model assumption, signifying that behavioral aspects significantly influenced speeding behavior among drivers. Nevertheless, affective and cognitive components were insignificant predictors. Furthermore, strong agreement with speeding countermeasures was observed among the participants.

Conclusion: In conclusion, sociodemographic characteristics and attitude have been proven to affect speeding behavior among drivers on Malaysian federal roads. The findings have important implications in designing driver risk profiles on federal roads to develop suitable countermeasures based on the 4E approach (engagement, education, enforcement, and engineering) to enhance road safety.

民航维修人员习惯性违章行为的SD建模研究

掌握习惯性违章行为形成过程中的反馈机制和发展规律可以为消除习惯性违章行为提供理论依据。基于系统动力学(SD)理论,建立了民航机务维修人员习惯性违章行为的动态模型,利用VENSIM软件模拟仿真。结果表明,惩罚力度从第1等级(惩罚力度由小到大分别对应1~10等级)到第6等级时,习惯性违章行为活跃水平依次减小,从第6等级到第10等级时,习惯性违章行为活跃水平依次增加。此外习惯性违章行为活跃水平对工作单卡的合理程度敏感性最强,组织应优先提高工作单卡的合理程度。
