The relationship between university students’ environmental identity,decision-making process,and behavior     

Allison Freed 《Environmental Education Research》2018,24(3):474-475

Environmental education scholars have argued for the need to focus on identity as a more predictive factor than attitude of individuals’ environmental behavior. We examine individuals’ decision-making as a mediating process between identity and behavior. University undergraduates (N = 299) were surveyed, with a select sub-sample interviewed. As expected, environmental identity was correlated with pro-environment behavior (recycling). However, students with lower pro-environmental identity also recycled regularly. Similarly, analysis of decision-making revealed most students, regardless of their environmental identity, do not think much when recycling. Environmental structures such as presence of recycling bins surfaced as a powerful influence on pro-environment behavior.  相似文献   

Educational impact on the relationship of environmental knowledge and attitudes     

A. K. Liefländer  F. X. Bogner 《Environmental Education Research》2018,24(4):611-624

This study examines the relationships between the environmental attitudes and environmental knowledge of schoolchildren within the framework of an environmental intervention. We employed questions from the 2-MEV model to monitor students’ environmental attitudes in terms of the model factors Preservation and Utilisation while concurrently monitoring three environmental knowledge dimensions (system, action-related and effectiveness knowledge) at three different test times during the course of a four-day field centre programme for fourth-graders (N = 133, M_age = 9.8 years). Probably due to measurement constraints (e.g. a ceiling effect, social desirability), we found no correlation between environmental knowledge and the attitude Preservation at all test times. The attitude Utilisation correlated negatively with all environmental knowledge dimensions, indicating that students who score higher on Utilisation are more likely, for example, to have and gain more system knowledge through programme participation than the other students or vice versa, as a causal relationship cannot be derived from our analyses: system knowledge may also influence Utilisation. In other words, children who refrain from (ab)using nature also seem to put more effort into improving their environmental knowledge and/or children who engage in learning about the environment will become less exploitative towards the environment.  相似文献   

Environmental education in southern Africa: a case study of a secondary school in the Okavango Delta of Botswana     

Kgosietsile Velempini  Bruce Martin  Thomas Smucker  Adah Ward Randolph  John E. Henning 《Environmental Education Research》2018,24(7):1000-1016

This study explored the extent to which teachers integrate environmental education and local environmental knowledge into the curriculum of a secondary school in the Okavango Delta of Botswana. In doing so, the study explored the potential value of place-based education in redressing concerns brought to light in postcolonial critiques of education in southern Africa. The study found that teachers sought to integrate environmental education into the curriculum through lessons that included references to local place names and local flora and fauna, lessons addressing issues related to environmental resource management in the region, and the acknowledgment and celebration of traditional lifestyle activities in the schools. The study also found that efforts to integrate environmental education into the curriculum were limited by a lack of educational resources needed to support these endeavors as well as a lack of adequate teacher training promoting this educational goal. The results also illustrate the potential value of place-based education in redressing the legacy of southern Africa’s colonial past in schools in Botswana and southern Africa.  相似文献   

Why do people accept environmental policies? The prospects of higher education and changes in norms,beliefs and policy preferences     

Niklas Harring  Sverker C. Jagers 《Environmental Education Research》2018,24(6):791-806

Pressing problems of environmental degradation are typically argued to require coordination, primarily through state intervention. Social scientists are struggling to understand how attitudes toward such state interventions are formed, and several drivers have been suggested, including education. People with university degrees are assumed to have certain values as well as the analytical skills to understand complex issues such as climate change. By using a unique panel data-set with students in different university programs (economics, law and political science), this study provides a better understanding of whether and how education affects environmental policy acceptance. One important finding is that university studies generate variation in support and scepticism toward different types of policy measures. For example, economics students tend to develop more positive attitudes toward market-based policy measures. This indicates a potential for education to increase the societal support often hindering the implementation of such policy tools.  相似文献

曲艳敏  陶以军  刘捷  杨璐  李潇 《科技管理研究》2018,(23)

伴随海洋油气开发活动逐渐增多,对其的监督管理提出了更高要求。本文通过梳理美国海洋油气勘探开发环境保护管理的法律体系,研究其在墨西哥湾漏油事件后的监督管理框架,剖析海洋开发活动事前、事中和事后的管理制度,归纳总结了美国海洋油气开发环境保护管理值得借鉴的经验：一是建立了较为完整的法律法规体系和衔接较为紧密的制度体系,二是在管理中善于运用经济处罚和油污责任信托基金等经济手段,三是反应迅速、运行高效的海上溢油应急体系发挥着重要作用。通过总结这些经验,希望对提升我国海上油气开发管理水平起到借鉴作用。  相似文献   

我国环境责任保险相关问题之探索分析     

何宁 《孝感职业技术学院学报》2009,12(3):90-94,14

环境污染及其损害已成为人类无法回避的共同问题,环境责任保险也已被国际社会证明是一种有效的环境风险管理的市场机制,因此我国建立环境责任保险制度势在必行。虽然有过试点实践,但是尚欠成熟。文章从环境责任保险承保机构模式、承保范围和保险赔偿金来源等几个方面,以理论分析和实证分析的方式探讨学界没有达成共识的一些问题,来探索适合我国国情的相关理论方法,并提出相关建设性意见。  相似文献

城市建筑节能技术的应用研究     

聂法臣 《环球赛鸽科技》2013,(24)

城市建筑节能主要体现在城市建筑的绿色节能技术上,绿色建筑在概念上主要包含如下几点：①节能,在这里主要是强调要我们减少各种各样的资源浪费;②保护环境,在这里主要是强调减少环境污染以及减少二氧化碳的排放数量;③满足人们使用上的要求,为人们提供的使用空间要做到“适用”、“健康”、“高效”。绿色建筑从设计、建设、使用、维护到拆除形成了的周期都有各种各样的节能及环保要求。这意味着在设计阶段就要重点考虑环境因素的利用,还要尽量地降低建设过程对环境造成的不良影响,且确保建筑在运行阶段能为人们提供低耗、舒适、健康的空间,并全力降低拆除时对环境所造成的危害程度。  相似文献   

Effects of high-intensity resistance circuit-based training in hypoxia on body composition and strength performance     

《European Journal of Sport Science》2013,13(7):941-951

Abstract

Hypoxic training methods are increasingly being used by researchers in an attempt to improve performance in normoxic ambients. Moreover, previous research suggests that resistance training in hypoxia can cause physiological and muscle adaptations. The primary aim of this study was to compare the effects of 8 weeks of high-intensity resistance circuit-based (HRC) training in hypoxia on body composition and strength performance. The secondary aim was to examine the effects of HRC on metabolic parameters. Twenty-eight male participants were randomly assigned to either hypoxia (Fraction of inspired oxygen [F_IO₂]?=?15%; HRC_hyp: n?=?15; age: 24.6?±?6.8 years; height: 177.4?±?5.9?cm; weight: 74.9?±?11.5?kg) or normoxia [F_IO₂]?=?20.9%; HRC_norm: n?=?13; age: 23.2?±?5.2 years; height: 173.4?±?6.2?cm; weight: 69.4?±?7.4?kg) groups. Training sessions consisted of two blocks of three exercises (Block 1: bench press, leg extension and front pull down; Block 2: deadlift, elbow flexion and ankle extension). Each exercise was performed at six repetition maximum. Rest periods lasted for 35-s between exercises, 3-min between sets and 5-min between blocks. Participants exercised twice weekly for 8 weeks, and body composition, strength and blood tests were performed before and after the training program. Lean body mass and bone mineral density significantly increased over time in the HRC_hyp (p?<?.005; ES?=?0.14 and p?<?.014; ES?=?0.19, respectively) but not in the HRC_norm after training. Both groups improved their strength performance over time (p?<?.001), but without group effect differences. These results indicate that simulated hypoxia during HRC exercise produced trivial effects on lean body mass and bone mineral density compared to normoxia.  相似文献
