Problem: Anyone drinking and driving has a high risk of being involved in an accident. Young male drivers, however, run the highest risk at the same levels of blood alcohol as other candidates, as they have more accidents than any other group. A better understanding of their motivations toward drinking and driving is needed to help create effective prevention. Method: In the present study, 115 male drivers aged 18–24 completed a questionnaire—based on Ajzen's theory of planned behavior—designed to study the motivational factors leading to drinking and driving. Results: Young males' intention to drink and drive is predicted by their attitudes, their perceived behavioral control (PBC), and, to a lesser degree, subjective norms. Impact on Industry: The results showing slightly positive PBC over driving after drinking suggest that work aimed at reducing this perception to a more realistic level is a potential prevention avenue.  相似文献

Urban ecological systems: scientific foundations and a decade of progress   总被引:9,自引:0,他引:9  
Urban ecological studies, including focus on cities, suburbs, and exurbs, while having deep roots in the early to mid 20th century, have burgeoned in the last several decades. We use the state factor approach to highlight the role of important aspects of climate, substrate, organisms, relief, and time in differentiating urban from non-urban areas, and for determining heterogeneity within spatially extensive metropolitan areas. In addition to reviewing key findings relevant to each state factor, we note the emergence of tentative "urban syndromes" concerning soils, streams, wildlife and plants, and homogenization of certain ecosystem functions, such as soil organic carbon dynamics. We note the utility of the ecosystem approach, the human ecosystem framework, and watersheds as integrative tools to tie information about multiple state factors together. The organismal component of urban complexes includes the social organization of the human population, and we review key modes by which human populations within urban areas are differentiated, and how such differentiation affects environmentally relevant actions. Emerging syntheses in land change science and ecological urban design are also summarized. The multifaceted frameworks and the growing urban knowledge base do however identify some pressing research needs.  相似文献

China's national sustainable development strategies were drafted under the guidance of Deng Xiaoping's theory on socialist construction with Chinese distinguishing features and, the theory and practice of sustainable development has further enriched and perfected Deng Xiaoping's theory. An in-depth study of Deng Xiaoping's theory is significant if we are to accurately understand our sustainable development program and how to best implement the strategies.  相似文献

Introduction: Children under five years are most at risk of experiencing fatal and nonfatal drowning. The highest proportion of drowning incidents occur in private swimming pools. Lapses in adult supervision and failures in pool barriers are leading contributory factors for pool drowning in this age group. Methods: We investigated the role of the theory of planned behavior social cognitions (attitude, subjective norm, and perceived behavioral control) as well as perceived barriers, planning, role construction, and anticipated regret on parents’ and carers’ intentions and habits toward two pool safety behaviors: restricting access and supervising children around private swimming pools. The study adopted a cross-sectional correlational design. Participants (N = 509) comprised Australian parents or caregivers with children aged under five years and access to a swimming pool at their residence. Participants completed a battery of self-report measures of social cognitive variables with respect to the swimming pool safety behaviors for their children. Results: Path analytic models controlling for past behavior indicated that subjective norm, planning, anticipated regret, and role construction were important predictors of habit, and subjective norm was a consistent predictor of intentions, for both behaviors. Planning predicted intentions in the restricting access sample, while attitudes, barriers, and role construction also predicted intentions in the supervising sample. Both models controlled for past behavior. Conclusion: Current findings indicate the importance of psychological factors for restricting access and supervising behaviors, with normative factors prominent for both reasoned (intentions) and non-conscious (habits) behavioral antecedents. It seems factors guiding restricting access, which likely require regular enactment of routine behaviors (e.g., ensuring gate is not propped open, pool fence meets standards), may be governed by more habitual than intentional processes.  相似文献

结合英语教学实践,依据Leo van Lier的意识原则(Awareness)和自主性原则(Autonomy),对高职高专院校英语专业学生进行了问卷调查。调查结果显示,高职高专院校英语专业学生的英语学习意识薄弱,动机不强。3A理论的启示是:发挥学生的主体作用,树立学生的语言学习意识,调动学生学习英语的主观能动性。  相似文献

从社会心理学的角度,通过问卷调查的方式,对驾驶员侵犯驾驶行为的产生动机进行分析;基于计划行为理论,研究构建了能揭示驾驶态度与行为关系的理论模型,并得出驾驶员对侵犯驾驶行为的态度、主观标准、知觉行为可控性等心理因素,通过行为意向的中介作用,对驾驶员实施侵犯驾驶行为具有预测作用的结论。同时,提出了从态度改变、建立社会支持体系、提高驾驶员的自我能力评估等方面入手对驾驶员侵犯驾驶行为进行矫正的策略。  相似文献

利用江苏省2008-2013年24个站的酸雨监测资料,分析出2008-2013年江苏省酸雨的强度和发生频率都有下降趋势,秋冬季酸雨发生频率高,夏季最低。基于信息扩散理论对全省酸雨进行风险评估,结果发现:年降水p H值和酸雨发生频率在不同风险水平分布特征较为一致,呈西北-东南逐渐增强趋势;年降水p H值80%的可能介于4.5~5.6之间,呈弱酸性;淮河以南地区酸雨发生频率的风险为40%的概率超过90%。  相似文献

In this article, we provide a critical review of the place of paradigm in health impact assessment (HIA) research and practice. We contend that most HIA practitioners have given insufficient attention to paradigm positioning when developing and applying HIA methodologies and that some concerns about current HIA practice can be attributed to this. We review HIA literature to assess the extent and nature of attention given to paradigm positioning and these related concerns. We then respond to our critique by exploring the implications, opportunities and challenges of adopting a critical realist paradigm, which we believe has the potential to help HIA practitioners to develop HIA methodology in a way that addresses these issues.  相似文献
