Transformational and transactional leaderships,empowerment climate,and innovation performance: A multilevel analysis in the Chinese context

Innovation through creativity is an important factor in the success and competitive advantage of organizations. Theory and research suggest that both leadership and organizational climate have important consequences for individual creativity. However, researchers have rarely considered the interactive effects of leadership and organizational climate. This study taking a “Substitute for Leadership” perspective, develops and tests the idea that empowerment climate affect the relationship between leadership and followers' creative performance. Data were collected from 93 teams, including 465 team members and 93 team supervisors, in a large multinational company based in China. Hierarchical linear modelling was used to examine the hypothesized cross-level model. As expected, transformational leadership and team empowerment climate were positively related to subordinates' creative performance and transactional leadership was negatively related to subordinates' creative performance. In addition, the relationship between leadership and subordinates' creative performance was moderated by team empowerment climate. The study resulted in the implication of several major variables for explaining individual creativity in the Chinese context.     

工作记忆中央执行成分对估算表现的影响

工作记忆中央执行成分在计算加工的诸多过程中发挥重要影响。以82名大学生为被试,采用双任务实验范式考察工作记忆中央执行成分对估算表现的影响。结果发现：1）估算过程需要中央执行成分的参与,增加中央执行成分负荷会导致估算准确率下降;2）无论是否增加中央执行负荷,问题大小效应在估算中均不明显;3）乘法个位数大小顺序会影响估算值的准确性,在有中央执行负荷时数字顺序效应明显。     

青少年身体不满意与自杀意念的关系:一个有调节的中介模型

为考察青少年对身体的满意度和自杀意念的关系，探讨自尊是否在青少年身体不满意和自杀意念的关系中起中介作用，以及这个过程是否受到友谊质量的调节作用。采用身体不满意量表、自杀意念量表、自尊量表和友谊质量量表对来自湖北、安徽、河南、吉林四省六所高中的802名高一学生进行调查，结果显示：（1）身体不满意对自杀意念具有显著的正向预测作用；（2）自尊在身体不满意和自杀意念的关系中起部分中介作用；（3）友谊质量在身体不满意通过自尊影响自杀意念的中介模型后半段起调节作用，即在友谊质量较低的青少年中，自尊对自杀意念的影响更大。因此，青少年身体不满意和自杀意念之间存在有调节的中介效应。     

社交网站中的自我呈现与青少年网络利他行为:网络社交效能和希望的作用

为考察社交网站中的积极自我呈现、真实自我呈现对青少年网络利他行为的影响以及网络社交效能和希望在其中的中介作用，采用社交网站中的积极自我呈现和真实自我呈现问卷、网络利他行为量表、网络社交效能问卷和希望量表对安徽、福建、河南、湖南、山西、天津、云南等省份八所中学的805名初中二年级学生（男生427名，女生378名；被试平均年龄为13.38岁，SD=0.63）进行问卷调查。研究显示：（1）社交网站中的积极自我呈现和真实自我呈现均能正向预测青少年网络利他行为；（2）网络社交效能在积极自我呈现与青少年的网络利他行为之间起中介作用，也在真实自我呈现与青少年的网络利他行为之间起中介作用；（3）希望在真实自我呈现与青少年的网络利他行为之间起中介作用。
