风险社会视域下“校园贷”问题的生成及应对   总被引:1,自引:0,他引:1  
"校园贷"是一个横跨"在场空间"与"缺场空间"的"跨界性"问题,以风险社会理论为视角进行分析,可有效地贯通网上、网下两个空间的情境性区隔,是从整体上对其进行解读的理想选择。它的异变主要涉及社会急剧转型、网络技术发展及大学生群体结构三个风险源:社会转型过程中风险的无序释放是催生"校园贷"问题的现实动因,网络技术的风险特征是催生"校园贷"问题的潜在根源,大学生群体消费欲望强而财商低的结构特点是催生"校园贷"问题的重要因素。防范"校园贷"风险的关键在于建构政府主导、社会参与、个体自省的风险应对共同体,以减少各类风险发生交叠、共振的频率。  相似文献

This article describes a community-based participatory action research (CBPAR) project that examined the postmigration living difficulties (PMLD), help-seeking and community resilience of recent Irish migrants to London (n = 176). The majority of respondents were young adults, in managerial or professional occupations and in good or very good health. Mixed methods indicate inadequate planning for relocation and poor social support as the main difficulties in the initial stages of migration. Community factors promoting resilience included employment opportunities, local and transnational supports, and cultural familiarity and acceptance. Community participation in the action orientated phase of this CBPAR is discussed.  相似文献

Human actions are complex stimuli containing several perceptual dimensions an observer could attend to. Research indicates that attention to the perceptual dimensions of action undergoes a process of perceptual narrowing between 4 and 10 months, during which infants’ attention to configural and temporal information in action decreases over time, while attention to hand information is maintained. This research explored whether infants’ active experience with grasping is related to perceptual narrowing in action. Across two studies, we tested 6‐month‐old infants’ attention to changes in these action dimensions and also assessed their grasping ability. Infants who were more proficient at grasping showed a pattern more consistent with perceptual narrowing (decreasing attention to configural and temporal information) relative to those less proficient at grasping, especially for attention to configural information. In addition, attention to hand information appears to undergo U‐shaped development between 4 and 10 months, as 6‐month‐olds did not recover attention to the hand change. These findings add to a growing body of research showing that infants’ motor experience broadly influences their perception of others’ action and may follow a complex developmental pathway that diverges from perceptual narrowing over the first year.  相似文献

It is generally difficult to separate the effects of divorce from selection when analyzing the effects of parental divorce on children’s risk behaviors. We used propensity score matching and longitudinal data methods to estimate the effects of parents’ divorce on their children’s binge drinking, alcohol consumption, tobacco use, marijuana use, and hard drug use. The children were between 12 and 18 years old in the first survey and between 18 and 24 years old in the second survey. Our results suggest that parental divorce significantly increased the probability of risk behaviors in their children. Moreover, many of these adverse impacts persisted over time, especially among teenage girls.  相似文献
