The varying effects of left–right ideology on support for the environment: Evidence from a Swedish survey experiment

Years of research show that left-leaning individuals are more supportive of environmental policies than right-leaning individuals. The explanation for the lower level of support among right-leaning individuals is their stronger preference for economic growth and lower acceptance of intervention in markets. However, recent cross-national studies have questioned whether the effect of ideology on environmental support is universal. A Swedish survey experiment shows that the effect of ideology varies greatly depending on how individuals think about the environment. Specifically, it demonstrates that if environmental support is contrasted with economic growth, then the effect of ideology is stronger as opposed to when environmental support is not juxtaposed with economic growth. Furthermore, among people who strongly perceive the environment as a left–right issue, there is a larger divide between left and right.     

Determinants of workers’ attitude toward low-carbon technology adoption: empirical evidence from Chinese firms

As the main contribution of China’s carbon emissions, low-carbon production in industrial firms becomes an inevitable choice, and industrial firm employees’ attitudes on low-carbon new technology directly influence the results of low-carbon production. Based on the Unified Theory of Acceptance and Use of Technology model, structural equation modeling was used to analyze the main factors influencing firm staff to accept low-carbon new technology. The study reveals that the employee’s social impact, performance expectation, effort expectations and convenient conditions, and employee characteristics are all main factors affecting their acceptance attitudes on low-carbon new technology. And social influence has the largest effect on employees’ acceptance attitudes toward low-carbon new technology. Accordingly, relevant policy recommendations are put forward for the future research direction.     

OPINIONS RELATING TO FLUORIDATION: DEVELOPMENT OF MEASURES1

ABSTRACT. Elected officials, technical specialists and the public are talking more about “citizen input” into the decision process, and how the people view a given issue or kind of public service. However, problem definition and valid instruments are needed before we can meaningfully predict or understand public attitude relating to a particular issue or concept. The fluoridation of community water supplies was chosen for the present methodological demonstration. This issue achieves a high level of controversy among many public segments [Crain, Katz and Rosenthal, 1969; Davis, 1959; McNeal, 1957]. By 1950, there was widespread endorsement for a national program relating to controlled water fluoridation. Yet, public acceptance of this particular technological advance has not been very high.     

公众态度和机构监督对大气污染的影响

虽然以往对于环境库兹涅兹曲线（EKC）的研究中考虑了正式制度因素如政府机构监督，但是较少考虑非正式制度因素.本文重点检验两种制度情境的影响，微观层面的环境态度形成的非正式制度以及宏观层面的环保机构监督形成的正式制度对大气污染排放量的影响.基于CGSS2010-2013和2015年的数据库，从中提取出体现环境态度的问题，将其赋值指标化后，作为制度情境纳入环境方程.经过公开数据的收集，得到我国26个省份2010-2014年5年的面板数据.通过固定效应和随机效应模型，发现机构监督与人均GDP的交互项对氮氧化物、烟（粉）尘、二氧化硫排放都有影响，但是公众态度与人均GDP的交互项只对烟（粉）尘排放有影响，从而对不同制度情境下的环境库兹涅兹曲线进行了探索.     

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。     

基于MIKE 21的长江江山制药排污口水环境影响分析——以江山制药公司污水处理站为例

为分析长江沿岸入河排污口设置对水环境的影响,采用MIKE 21建立了长江马鞍山-高桥段二维非稳态水量水质模型,并以江山制药公司污水处理站为例,对其排污口迁址改建前后的水环境影响进行模拟.结果 表明,较于原排污口排放,拟设排污口在执行新排放标准情况下,对九圩港入江断面水质有改善作用,COD、NH3-N、TP的改善率分别为...     

旅游体验对旅游者环境态度和环境行为影响的纵向追踪研究

目前国内关于旅游体验对环境态度和行为影响的纵向追踪研究较为缺乏。论文以自然旅游地黄山为案例地,通过纵向调查,采用配对样本t检验比较同一批次旅游者游前、游后以及3个月后的环境态度和环境行为。研究发现：1）旅游体验对旅游者环境态度基本没有影响。2）旅游体验对旅游者环境行为存在显著影响。短期影响表现为：特定地点环境责任行为中的教育、身体和法律行动显著改善,一般环境责任行为中教育、消费、说服、身体和法律行动显著改善;长期影响表现为：特定地点环境责任行为中的教育、消费、身体行动和一般环境责任行为中的消费、身体、法律行动显著改善。环境行为的改变主要是通过旅游体验中的认知和情感刺激引起的,包括预期愧疚、集体自豪感、环境知识、负面后果认知、自我效能、环境解说等因素。文章最后讨论了管理意义和研究不足。     

基于心态指标的煤矿瓦斯爆炸区间数模糊评价

为了评估煤矿瓦斯爆炸的安全性,根据瓦斯爆炸的形成条件和事故致因理论,建立了评价体系。然后采用一种新的区间数模糊评价方法,建立数学模型。传统的区间数模糊评价方法是根据最大隶属度原则判断该对象的优劣,不能进行多个对象之间的评价。该方法综合考虑了最大隶属度和评语集,提出区间数的内积公式,进而得到每个对象的综合分数,通过比较其大小进行多个对象之间的评价。考虑到决策者不同心态时对决策方案的影响,引入心态指标,通过调节心态指标来比较综合分数,从而得出煤矿之间的安全性大小。最后,将该方法应用到3所煤矿,运用基于中点值的区间数排序方法对综合评判向量进行分析,所得结果与该方法的结果基本一致,从而验证该方法的正确性。     

分层水环境曝气诱导形成内波的过程与特性

采用分层水库模型,在平均温度梯度为0.37℃/cm条件下,开展了系统的曝气诱导内波的中试研究.分析了曝气诱导形成内波的过程,探究了曝气诱导形成内波的类型,重点揭示了曝气扰动源形式和跃温层厚度对内波形成过程和特性的影响.实验结果表明：扬水曝气产生的气水两相流是一种非定常的周期性扰动源,气水两相流的尾迹带动整个模型水体上下振动,这种振动在分层水体跃温层处诱导形成内波.从激发源角度上说,它是一种尾迹效应波.气弹释放周期在44.06～58.69s之间时,内波波高达到最大,当气弹释放周期达到180s时不能形成连续的内波;曝气器出流口增大,内波波高、周期呈增大趋势.分层水体的跃温层厚度也影响内波的形成,相同温度梯度条件下,随着跃温层厚度的增加,内波的波高、周期随之增大.
