From childhood nature experiences to adult pro-environmental behaviors: An explanatory model of sustainable food consumption

Abstract

In two studies, the role of nature experiences and social norms during childhood is explored next to adulthood biospheric values, connectedness to nature, environmental identity, and objective knowledge in relation to pro-environmental behaviors. Study 1 (N?=?185) tested the hypothesized model in the realm of general pro-environmental behaviors and sustainable fruit consumption on a sample of students. Study 2 (N?=?155) tested the model in the realm of sustainable seafood consumer choice on a general population sample. Path analyses show consistent results across samples. Results show that childhood nature experiences and exposure to pro-environmental social norms during childhood are related to adulthood development of connectedness with nature and biospheric values; these, in turn, help in shaping adulthood environmental self-identity ultimately influencing the enactment of sustainable food choices during adulthood. These findings point toward the relevance of childhood experiences for pro-environmental behaviors as compared to the provision of information. The role of objective knowledge across samples is inconsistent, thus requiring future investigations.     

商品房销售欺诈行为的法律适用

随着我国市场经济的发展和住房制度的改革,房地产市场逐渐活跃起来。然而,商品房销售过程中的不法行为也随之出现。从应当适用《消费者权益保护法》对商品房销售欺诈行为加以调整的角度,探讨如何在我国现有法律框架下,加大对商品房消费者合法权益的保护力度。     

不良会计行为的经济学分析

论我国反垄断法的规制对象

随着我国加入WTO步伐的加快，制定了一部反垄断法实属当务之急。由于目前对垄断一词没有明确的界定，我国反垄断法应以什么为规制对象是一个值得探讨的问题。本从对经济学意义的垄断与法学意义上的垄断比较分析入手，在考察世界几个主要国家反垄断法的规制对象的基础上，阐述了我国反垄断法所应规制的对象。以对我国反垄断立法有所裨益。     

中科院继续教育平台使用现状的分析

继续教育作为一种特殊的教育形式,致力于提高专业技术人员的知识和技能,因此受到职业与专业领域的广泛关注。面对日益迫切的需求,学者设计了许多针对继续教育的教学模式,其中慕课是最典型的一种。但是,如果缺乏有效的管理,慕课很可能会弱化成在线媒体资料库,并失去对用户的吸引力。为规避此类风险,我们对中科院-CASMOOC进行了数据提取和统计分析,并设计了相应的推荐策略。首先,我们研究了CASMOOC的服务目标、应用场景及服务效果。接下来,利用平台积累的学习数据,我们分析了用户和课程的特征。基于用户特征,我们从四个维度将用户分成九种类型;基于课程特征,我们确定了可供推荐的典型课程。最后,针对九类用户在四个分类维度上的差异,我们设计了一种组合推荐策略,以达到既满足各类用户的学习习惯,也可指导他们参加专业领域课程的目标。策略应用后四个月的统计数据显示,用户对CASMOOC的使用模式正在得到改善。     

我国幼儿攻击性行为干预效果及调节因素的元分析

为综合评价我国幼儿攻击性行为研究干预效果,进一步探究幼儿攻击性行为干预的调节因素,以"幼儿攻击性行为干预""幼儿冲突行为干预""幼儿欺负行为干预"为检索策略,运用Reva Man 5.3软件对我国幼儿攻击性行为干预实验结果进行元分析,并分析干预方式、干预对象、干预时间、测量工具等调节因素对干预效果的影响(纳入26个独立效应量,N=875)。结果表明:我国幼儿攻击行为干预整体上达到中等强度效果量〔SMD=-0.77,95%CI(-0.91,-0.62),P<0.000 1〕;行为干预比游戏干预更有效;干预时长与干预效果存在动态的关系;以家庭为对象的干预方式效果优于直接作用于幼儿的干预方式;测量工具的差异会对研究结果产生一定影响。     

Can playscapes promote early childhood inquiry towards environmentally responsible behaviors? An exploratory study

This paper investigates young children’s exploratory play and inquiry on playscapes: playgrounds specifically designed to connect children with natural environments. Our theoretical framework posits that playscapes combine the benefits of nature and play to promote informal science exploration of natural materials. This, in turn, is expected to lead to environmental science literacy, which in turn is likely to strengthen a child’s ecological identity and lead to environmentally responsible behaviors (ERBs). The following questions are of specific interest: to what extent do children go beyond observations and explorations and use science-specific representations and language during their play on playscapes? What locations on the playscape afford science-specific activities? And how do these activities relate to their play on the playscape? In an attempt to answer these questions, we describe data obtained from a video analysis of preschoolers visiting a playscape. As a means of initial comparison, we also analyzed data obtained from a traditional playground. We examine the intersection of children’s play and inquiry within specific areas of interest at the two sites. The two sites vary in many dimensions, including size, familiarity, and access to natural materials. Nevertheless, our data provide initial support for our hypothesis that natural environments promote explorations and inquiry, fostering ERBs.
