The Relative Importance and Interaction of Contextual and Methodological Predictors of Mean rWG for Work Climate

A variety of collective phenomena are understood to exist to the extent that workers agree on their perceptions of the phenomena, such as perceptions of their organization’s climate or perceptions of their team’s mental model. Researchers conducting group-level studies of such phenomena measure individuals’ perceptions via surveys and then aggregate data to the group level if the mean within-group agreement for a sample of groups is sufficiently high. Despite this widespread practice, we know little about the factors potentially affecting mean within-group agreement. Here, focusing on work climate, we report an investigation of a number of expected contextual (social interaction) and methodological predictors of mean r_WG, a common statistic for judging within-group agreement in applied psychology and management research. We used the novel approach of meta-CART, which allowed us to assess the relative importance and possible interactions of the predictor variables. Notably, mean r_WG values are driven by both contextual (average number of individuals per group and cultural individualism-collectivism) and methodological factors (the number of items in a scale and scale reliability). Our findings are largely consistent with expectations concerning how social interaction affects within-group agreement and psychometric arguments regarding why adding more items to a scale will not necessarily increase the magnitude of an index based on a Spearman-Brown “stepped-up correction.” We discuss the key insights from our results, which are relevant to the study of multilevel phenomena relying on the aggregation of individual-level data and informative for how meta-analytic researchers can simultaneously examine multiple moderator variables.

     

默认选项设置的助推效果：来自元分析的证据

默认选项设置指通过设置默认选项以增加人们选择该选项可能性的助推方法, 近年来被越来越多地运用于促进公众积极行为上, 然而这种方法在有效性上却受到了来自公众和学者的质疑。据此, 本研究运用元分析法整合了近几年有关默认选项设置的已有实证研究, 分析该助推手段的有效性, 并进一步考察可能影响其有效性的相关变量。研究共纳入符合要求的原始文献56篇, 含92个研究, 结果发现：(1)默认选项设置的确能有效助推人们的行为; (2)默认选项设置的助推有效性在东、西方文化下存在显著差异, 其在西方文化背景下的助推效果要显著好于其在东方文化背景下的使用; (3)默认选项设置的助推有效性在不同情境应用领域中存在显著差异, 相较于健康和环保领域, 默认选项设置在金钱相关的情境领域下助推效果更好。

社会性线索对内隐和外显元认知监控的影响

本研究以词图匹配材料为学习材料,以“大多数人选择的情况”为社会性线索,通过分析行为表现和眼动指标,探讨了社会性线索对内隐和外显元认知监控的影响。结果显示：（1）第一次信心判断时,外显信心判断显著高估,内隐信心判断较为准确。第二次信心判断时,在线索一致条件下,外显信心判断等级显著高于内隐信心判断。（2）在提供社会性线索阶段和第二次再认阶段,与线索一致条件相比,线索不一致条件下被提示项的注视时间更短,而未提示项的注视时间更长,且个体改变选择的次数显著增多。结果表明：内隐和外显元认知监测存在分离,内隐监测的准确性更高,外显监测受社会性线索的影响更大;而内隐和外显的元认知控制受社会性线索的影响趋同。

A robust vision-based method for staircase detection and localization

A robust vision-based staircase identification method is proposed, which comprises 2D staircase detection and 3D staircase localization. The 2D detector pre-screens the input image, and the 3D localization algorithm continues the task of retrieving geometry of the staircase on the reported region in the image. A novel set of principal component analysis-based Haar-like features are introduced, which extends the classical Haar-like features from local to global domain and are extremely efficient at rejecting non-object regions for the early stages of the cascade, and the Viola–Jones rapid object detection framework is improved to adapt the context of staircase detection, modifications have been made on the scanning scheme, multiple detections integrating scheme and the final detection evaluation metrics. The V-disparity concept is applied to detect the planar regions on the staircase surface and locate 3D planes quickly from disparity maps, and then, the 3D position of staircase is localized robustly. Finally, experiments show the performance of the proposed method.     

Relationships Between Social Support,Internal Assets,and Life Satisfaction in Korean Adolescents

In previous literature, social support has been reported to have a significant, positive relationship with life satisfaction. However, few studies have examined this relationship among Korean youths and how their psychological functioning is associated with both social support and life satisfaction. This study investigated the associations between different sources of social support (i.e., family, peer, and teacher), psychological factors (i.e., self-efficacy and emotional regulation), and life satisfaction, in a sample of 1133 Korean adolescents. The possibility of sex differences in these relationships was also investigated. Results indicated that only family support had a direct relationship with life satisfaction for male adolescents; however, all three types of social support were found to have a significant, indirect relationship with life satisfaction for male adolescents through both psychological factors. In contrast, all three types of social support had a direct relationship with life satisfaction of female adolescents. Additionally, self-efficacy had a mediating effect on the relationship between the social support from family and teachers and life satisfaction of female adolescents. The results and implications of the study are discussed.     

建构反应题中能力估计准确性的影响因素:评分者人数和项目个数的交互作用
