定量分析能源效率以及温室气体减排项目和政策中的协同效益方面的国际经验     

Ali Hasanbeigi  Grace Wu  Lynn Price 《科学与管理》2013,(3):3-6

提高能效和燃料转换效率是温室气体减排战略的一部分。过去二十年,很多研究显示这两方面带来气候变化以外的好处,多半介于这些政策方案实施成本的30%到超过100%。国际上,政策制定者对于分析能效政策和燃料转换效率政策同时纳入对温室气体和非温室气体两方面影响的探讨愈来愈感兴趣。欧盟、美国与日本已开发出一套相当成熟的方法。通常,协同效益的定量工作可分为三类:(1)协同效益模型;(2)事前的政策评估方法;(3)由学者建立的框架,意在改善这方面的研究,并将协同效益应用到更多的地区和政策方案上。 表ES-1将协同效益定量方面的几个重点模型、指南和框架做了摘要。  相似文献   

Interplay between childhood maltreatment, parental bonding, and gender effects: impact on quality of life

OBJECTIVE: The aim of this study was to examine associations between childhood adversity, parental bonding, gender, depressive symptoms, and quality of life in non-treatment-seeking adults from the community. METHOD: Effects of differential parental rearing were compared in adults who reported a high degree of childhood maltreatment (n=72) and those who reported no significant adverse events in childhood (n=69). Subjects completed retrospective measures of childhood maltreatment and perceived parenting style, as well as measures of current depressive symptoms and quality of life. RESULTS: The subjects without childhood maltreatment were younger and endorsed less current depressive symptomatology than did subjects with childhood maltreatment. While the subjects without a history of maltreatment reported more "optimal" bonding experiences with their parents, the maltreatment group members were more likely to characterize their early parental bonding experiences in terms of "affectionless control" (p<.001 for both maternal and paternal parenting), "affectionate constraint" (p=.025 for maternal parenting and p=.004 for paternal parenting), or "weak or absent" bonding (p<.001 for both maternal and paternal parenting). Results of a multiple regression analysis revealed that overall quality of paternal care (p=.015) and current level of depressive symptoms (p<.001) were significant independent predictors of adult quality of life. Gender effects between subjects providing parental bonding data were limited to the group with childhood maltreatment. CONCLUSION: These findings extend previous work documenting a relationship between early life maltreatment and suboptimal parental bonding, suggesting gender-specific effects of maternal and paternal care. Effects of childhood maltreatment on quality of life in adulthood appear to be linked with the quality of childhood paternal care and the occurrence of depressive symptomatology in adulthood, suggesting possible targets for primary or secondary prevention.  相似文献   

Remote electronic examinations: student experiences     

Peter Thomas  Blaine Price  Carina Paine  & Mike Richards 《British journal of educational technology : journal of the Council for Educational Technology》2002,33(5):537-549

This paper presents the findings from a small–scale experiment investigating the presentation of a synchronous remote electronic examination. It discusses the students' experiences of taking such an examination. The study confirms that the majority of participants found the experience at least as good as a conventional written examination. In addition, typing answers does not prevent students from producing answers in the time available. However, the pressure of time continues to be a major cause of anxiety for students. The paper discusses technical issues, particularly those related to the loss of communications during the 3–hour duration of the exam. Although software processes were available to save and restore students' answers throughout the examination, problems still occurred and more robust software is required.  相似文献   

Envisioning a meaningful future and academic engagement: The role of parenting practices and school‐based relationships          下载免费PDF全文

In contrast to the focus on short‐term, extrinsic goals in our society (e.g., wealth, prestige), positive youth development scholars have highlighted the need for parents and schools to help youths cultivate and plan for long‐term, intrinsic, and meaningful goals (i.e., envisioning a meaningful future), arguing that envisioning a meaningful future is potentially inspiring and associated with better outcomes for youths. Envisioning a meaningful future includes being future‐oriented and planful and having a sense of purpose, a life focus that provides deep meaning to life and contributes to the good of society. This study used structural equation modeling to examine the direct and indirect effects of parental and school relationships on envisioning a meaningful future and academic engagement in a diverse sample of adolescents (n = 624). Parental and school‐based relationships were positively associated with academic engagement, and this association was partially mediated by envisioning a meaningful future. Analyses revealed the importance of parental and school relationships in engaging youths in developing a vision for a meaningful future toward the goal of academic engagement. Variations between African‐Americans and Whites, and across grade and parental education levels are discussed.  相似文献   

Getting to Evo-Devo: Concepts and Challenges for Students Learning Evolutionary Developmental Biology     

Anna Hiatt  Gregory K. Davis  Caleb Trujillo  Mark Terry  Donald P. French  Rebecca M. Price  Kathryn E. Perez 《CBE life sciences education》2013,12(3):494-508

To examine how well biology majors have achieved the necessary foundation in evolution, numerous studies have examined how students learn natural selection. However, no studies to date have examined how students learn developmental aspects of evolution (evo-devo). Although evo-devo plays an increasing role in undergraduate biology curricula, we find that instruction often addresses development cursorily, with most of the treatment embedded within instruction on evolution. Based on results of surveys and interviews with students, we suggest that teaching core concepts (CCs) within a framework that integrates supporting concepts (SCs) from both evolutionary and developmental biology can improve evo-devo instruction. We articulate CCs, SCs, and foundational concepts (FCs) that provide an integrative framework to help students master evo-devo concepts and to help educators address specific conceptual difficulties their students have with evo-devo. We then identify the difficulties that undergraduates have with these concepts. Most of these difficulties are of two types: those that are ubiquitous among students in all areas of biology and those that stem from an inadequate understanding of FCs from developmental, cell, and molecular biology.  相似文献   

Using outdoor learning to augment social and emotional learning (SEL) skills in young people with social,emotional and behavioural difficulties (SEBD)     

Alan Price 《Journal of Adventure Education & Outdoor Learning》2013,13(4):315-328

ABSTRACT

Under-developed social and emotional learning (SEL) skills limit educational progress and make it difficult for children and young people with social, emotional and behavioural difficulties (SEBD) to form effective relationships with peers and ADULTS. This paper focuses on an SEL intervention set within an outdoor learning context. The research was practitioner led and used an action research (AR) approach to implement and evaluate the SEL intervention. Research participants (aged 12–13 years) were recruited from a UK special school and were all considered to have SEBD. The paper provides evidence for the specific SEL skills that participation in outdoor learning can enhance. The evidence suggests that outdoor learning can be an effective approach for educators wishing to augment the SEL skills of young people with SEBD.  相似文献

Possessions theory of persuasion: An examination of its basis and range     

James Price Dillard  Kim Witte 《Communication Studies》2013,64(3-4):188-199

Possessions theory claims that individuals learn to relate to their possessions in either an instrumental or symbolic fashion, and that this object orientation transfers to attitudes. Implicit in the theory is the notion that instrumental and symbolic orientations anchor the poles of a single continuum. The results of the first study tested that assumption and found that a bivariate conception was more empirically defensible than a bipolar conception. Study 2 was concerned with the scope of the theory's predictions for persuasion. The possessions orientation of women at‐risk for breast cancer was measured and they were then exposed to either a symbolic or instrumental message both of which asked them to participate in a clinical trial of a breast cancer preventative. Although no effects were observed on attitude toward participation nor on intention to participate, instrumental orientation showed a reliable, positive relationship with judgments of the persuasiveness of the messages.  相似文献
