“But it doesn’t come naturally”: how effort expenditure shapes the benefit of growth mindset on women’s sense of intellectual belonging in computing

Research suggests growth mindset, or the belief that knowledge is acquired through effort, may enhance women’s sense of belonging in male-dominated disciplines, like computing. However, other research indicates women who spend a great deal of time and energy in technical fields experience a low sense of belonging. The current study assessed the benefits of a growth mindset on women’s (and men’s) sense of intellectual belonging in computing, accounting for the amount of time and effort dedicated to academics. We define “intellectual belonging” as the sense that one is believed to be a competent member of the community. Whereas a stronger growth mindset was associated with stronger intellectual belonging for men, a growth mindset only boosted women’s intellectual belonging when they did not work hard on academics. Our findings suggest, paradoxically, women may not benefit from a growth mindset in computing when they exert a lot of effort.     

安徽省与周边省份资本分布情况比较研究

将安徽、山东、江苏、江西四省并列,对90年代以来影响各省资本分布的各个因素:区域经济增长差异、财政转移支付差异、信贷投放差异、外商直接投资利用差异进行了深入分析并对四者所反映出来的情况与问题做了系统研究,从而发现从中央财政支付转移的角度看,山东、江苏二省每年都有相当数额的财政收入上缴中央政府,而安徽、江西二省2000年以来每年都接受大量的中央政府财政补贴,并有逐年增大的趋势.从银行及其资本渠道来看,四省均出现资本外流现象.

棉花施用惠满丰有机复混肥增产效应研究

在当季不施肥,皮棉产量50kg/667m~2以上的生产条件下,棉花施用惠满丰有机复混肥30-70kg/667m~2,伏前桃增加1-1.5个,株高增加9.9-17.1cm,茎粗增加0.2-0.8mm,有效果枝增加约1.3个,单株成铃数增多1.1-3.1个,单铃重约增加0.4-0.5g,霜前花率提高3-9个百分点,衣分、子指也有所提高,比对照增产皮棉14.1-31.8kg/667m~2,增幅27.4％-61.1％(平均45％)。在等养分量情况下,惠满丰有机复混肥肥效优于化肥。惠满丰有机复混肥的经济合理施肥量为70kg/667m~2。

Statistical Power of the Multiple Domain Latent Growth Model for Detecting Group Differences

The latent growth model (LGM) in structural equation modeling (SEM) may be extended to allow for the modeling of associations among multiple latent growth trajectories, resulting in a multiple domain latent growth model (MDLGM). While the MDLGM is conceived as a more powerful multivariate analysis technique, the examination of its methodological performance is very limited. Hence, the present study compared the power of the MDLGM with that of a set of univariate LGMs for detecting group differences in growth rates over time using a Monte Carlo study with a two-group and two-domain design. The results indicated that there were different scenarios where the power rates for the MDLGM were greater than that of the set of LGMs (and vice versa) due to a joint function of the two domains’ intercorrelation size and the group difference effect size.
