Approaching math increases math = me and math = pleasant

In two studies, we examined the effect of extensive practice in approaching math on implicit identification with math, implicit math attitudes, and behavior during a math test. The results from Study 1 demonstrated that women trained to approach math showed more identification with and positive implicit attitudes toward math than women trained to avoid math. Notably, this latter pattern of findings was only evident for women low in initial identification with this field. The results from Study 2 replicated these findings by showing that women who were initially low in math identification and trained to approach math showed more implicit identification with math and attempted more items on a math test than women trained to respond to math in a neutral way. The implications of these findings for current theorizing on the gender gap in women’s representation in math related careers are discussed.     

肢体伤残者心理康复的试探性研究

三年来,根据接待配装假肢及康复治疗伤残病人的实际情况,我们选择了感觉、知觉和记忆三个项目,进行了测定,即:(1)伤残部位和对应部位的两点阈值测定;(2)装戴假手后提重差别阈限的测定;(3)再认能力测定。结果表明,这些测定对伤残病人的康复治疗和心理评定都有一定的参考价值。

Dislocations and cracks at Vickers indentations in (0 0 0 1) GaN single crystals

Single-crystal (0 0 0 1) GaN samples have been deformed with a Vickers indenter at room temperature using loads in the range from 0.02 to 4.90 N. Dislocations and cracks at the indentations were examined by means of scanning electron microscopy, cathodoluminescence, light microscopy and transmission electron microscopy. Geometrical relations could be found between the dislocation arrangement, cracks and the orientation of the indenter. The orientation of the indenter has only a slight effect on the dislocation pattern, but the crack system is predominantly determined by the symmetry and the orientation of the indenter.
