Effects of Coastal Lighting on Foraging Behaviorof Beach Mice

Abstract:  Introduction of artificial light into wildlife habitat represents a rapidly expanding form of human encroachment, particularly in coastal systems. Light pollution alters the behavior of sea turtles during nesting; therefore, long-wavelength lights—low-pressure sodium vapor and bug lights—that minimize impacts on turtles are required for beach lighting in Florida (U.S.A.). We investigated the effects of these two kinds of lights on the foraging behavior of Santa Rosa beach mice (  Peromyscus polionotus leucocephalus ). We compared patch use and giving-up densities of mice for experimental food patches established along a gradient of artificial light in the field. Mice exploited fewer food patches near both types of artificial light than in areas with little light and harvested fewer seeds within patches near bug lights. Our results show that artificial light affects the behavior of terrestrial species in coastal areas and that light pollution deserves greater consideration in conservation planning.

基于24Model的矿工怠工行为 管理模式架构及策略研究

为减少矿工怠工行为,基于24Model研究矿工怠工行为的管理模式架构及策略。首先,基于冰山模型理论分析矿工怠工行为的影响因素;其次,基于24Model和行为修正理论提出集怠工行为识别、行为原因分析、行为管理策略选择和行为修正评估于一体的矿工怠工行为管理模式架构;最后,提出了针对性的管理策略。对于提高煤矿企业矿工的工作绩效具有重要的理论意义和实践价值。     

黑色金属材料在长江淡水中的腐蚀行为

通过现场暴露试验,获得了2种碳钢、3种不锈钢及1种不锈钢与碳钢复合板材料在武汉长江淡水中的4年腐蚀试验结果,总结了它们的腐蚀行为。结果表明,Q235和16Mn碳钢在武汉长江中有较高的腐蚀率和明显的点蚀,稳定腐蚀率为0.055 mm/a;暴露4 a,奥氏体不锈钢304和316L没有明显腐蚀,而马氏体不锈钢430有较明显的点蚀和缝隙腐蚀;马氏体不锈钢0Cr13Ni5Mo与Q345C复合钢板在长江淡水中使用4 a后,0Cr13Ni5Mo发生严重的点蚀,说明马氏体不锈钢在淡水中的应用应慎重。     

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。     

农药对农田蜘蛛生态效应的研究进展

农药对农田蜘蛛的生态效应是进行农田害虫综合防治的生态学基础.本文综述了农田蜘蛛接触和吸收农药的主要途径、农药对蜘蛛的生态效应、蜘蛛对农药的抗性以及农药对蜘蛛的致死效应等研究现状.关于农药对农田蜘蛛亚致死效应的研究,特别是分子、生化、生理、行为等方面的异常,国内外报道不多,因此这方面的研究工作有待于进一步加强.参47     

Efficacy-based and normative interventions for facilitating the diffusion of conservation behavior through social networks

Research suggests that encouraging motivated residents to reach out to others in their social network is an effective strategy for increasing the scale and speed of conservation action adoption. However, little is known about how to effectively encourage large numbers of residents to reach out to others about conservation causes. We examined the influence of normative and efficacy-based messaging at motivating residents to engage in and to encourage others to participate in native plant gardening in their community. To do so, we conducted a field experiment with messages on mailings and tracked native plant vouchers used. Efficacy messages tended to be more effective than normative messages at increasing residents’ willingness to reach out to others to encourage conservation action, as indicated by a several percentage point increase in native plant voucher use by residents’ friends and neighbors. Messages sometimes had different impacts on residents based on past behaviors and perceptions related to native plant gardening. Among these subgroups, efficacy and combined efficacy and norm messages most effectively encouraged individual and collective actions, as indicated by increased voucher usage. Our findings suggest that interventions that build residents’ efficacy for engaging in a conservation behavior and for reaching out to others may be a promising path forward for outreach. However, given our results were significant at a false discovery rate cutoff of 0.25 but not 0.05, more experimental trials are needed to determine the robustness of these trends.     

农户从事生态循环农业意愿与行为的决定:市场收益还是政策激励?

发展生态循环农业是我国新时期转变农业发展方式的战略选择,农户是生态循环农业的经营主体和利益相关者,厘清农户参与生态循环农业的根本动机,对于制定有效的生态循环农业推广措施具有重要意义。文章基于湖北省391份农户调查数据,首先,在文献回顾的基础上提出市场收益、政策激励对农户生态循环农业从事意愿与行为影响路径的基本假设,并利用OLS方法分析市场收益和政策激励对农户从事生态循环农业意愿与行为的影响;其次,运用优势分析法评估市场收益类变量和政策激励类变量影响农户意愿与行为过程中的相对重要性;最后,通过交互效应检验市场收益类变量和政策激励类变量间的交互作用。结果表明:收入预期对农户从事生态循环农业的意愿与行为均有直接的积极影响,是促进农户从事生态循环农业的最重要的因素;焚烧秸秆惩罚政策和废弃物资源化补贴政策对农户从事生态循环农业的意愿有积极影响,沼气池建设补贴政策和废弃物资源化补贴政策对农户生态循环农业行为有促进作用;收入预期与废弃物资源化补贴政策在影响农户生态循环农业行为的过程中存在互补效应。本研究认为,市场收益是刺激农户采纳生态循环农业生产模式的首要因素,因此,要着力完善生态农业市场体系,增强生态农产品的市场竞争力,提升农户对生态循环农业的盈利信心;另外,政策激励对于农户采纳生态循环农业具有促进作用,应该做到约束与激励并行,同时注意加强农业政策的科学设计与落实执行。     

Best Practices in Environmental Communication: A Case Study of Louisiana's Coastal Crisis

This mixed-method case study of environmental communication best practices in Louisiana, USA, identifies trends and approaches as informed by environmental psychology. The results provide key insights for environmental communicators, especially communicators in coastal regions. In-depth interviews with both environmental psychologists and environmental communicators showed that both groups emphasized knowing the audience, telling local stories, building relationships with target audiences and targeted messaging. Both psychologists and communicators also frequently mentioned general messaging concerns of source credibility, avoiding controversial terms and talking about issues, impacts and solutions to which the target audience can relate. A representative survey revealed that Louisiana residents are most interested in hearing about how environmental issues such as climate change, coastal land loss and flooding are affecting their own communities. This finding supports the idea that environmental communicators could do a better job tapping into strong place attachment and sense of community among coastal residents to promote action.
