Formation of profuse <c+a> dislocations in deformed calcium-containing magnesium alloys

We report that <c+a> pyramidal slipping could be more easily activated in textured Mg–Ca alloys with increasing Ca contents dissolved in α-Mg matrix under tensile deformation, and it is proposed that the decreased stacking fault energy plays the critical rule. In contrast, only twins and <a> basal dislocations are observed in the compressed samples. The results would provide insight into understanding of the deformation mechanism and designing more ductile Mg alloys.     

Parental Corporal Punishment and Girls’ Self-Esteem: The Moderating Effects of Girls’ Agency and Communion in China

The current study aimed to examine the moderating effects of girls’ agency and communion in the links between both fathers’ and mothers’ corporal punishment and girls’ self-esteem in China. Chinese girls (n?=?302) enrolled in grades 4–8 were instructed to independently complete the Parent-Child Conflict Tactics Scale (CTSPC), the Children’s Sex Role Inventory (CSRI), the Global Self-Worth subscale of Self-Perception Profile for Children (SPPC), and demographic items. Results indicated that both fathers’ and mothers’ corporal punishment were not directly associated with girls’ self-esteem, whereas both agency and communion were positively associated with girls’ self-esteem. In addition, both fathers’ and mothers’ corporal punishment were significantly and negatively associated with self-esteem for girls with lower levels of agency but not for the girls with higher levels of agency. The current results extend the growing evidence against using corporal punishment as a child-rearing practice and highlight that intervention programs need to focus on eliminating, or at least decreasing, both mothers’ and fathers’ corporal punishment. Additionally, parents and educators need to move from the traditional gender-related attributes to encourage the development of both agency and communion in girls.

Social attention across borders: A cross-cultural investigation of gaze cueing elicited by same- and other-ethnicity faces

The gaze-cueing effect is a robust phenomenon which illustrates how attention can be shaped by social factors. In four experiments, the present study explored the interaction between the ethnic membership of the participant and that of the face providing the gaze cue. Firstly, we aimed to further investigate the differential impact of White, Black, and Asian faces on the gaze-cueing effect in White individuals. Secondly, we aimed to explore, for the first time, the impact of faces belonging to different ethnicities on gaze cueing in Chinese participants. The results allowed to rule out alternative accounts and showed that White participants exhibit a gaze-cueing effect for White and Asian faces, but not for Black faces, consistent with previous studies. As regards Chinese participants, the overall findings suggested a stronger gaze-cueing effect for White faces than for Asian faces. The results are discussed with reference to differences in the perceived social status of the various groups, pointing to the need of taking into account different cultural contexts.     

Are training and transfer effects of working memory updating training modulated by achievement motivation?

Previous studies examining effects of working memory (WM) updating training revealed mixed results. One factor that might modulate training gains, and possibly also transfer of those gains to non-trained cognitive tasks, is achievement motivation. In the present Studies 1 and 2, students with either a high (HAM) or low (LAM) achievement motivation completed a 14-day visuospatial WM updating training program. In Study 2, the students also performed a set of tasks measuring other executive functions and fluid intelligence prior to and after training. In both studies, the HAM students displayed a larger training gain than the LAM students. Study 2 revealed that after training, both groups showed better performance on the near-transfer but not far-transfer tasks. Importantly, the differential training gain was not associated with better post-training performance for the HAM compared to the LAM students on any of the transfer tasks. These results are taken to support a modulatory role of achievement motivation on WM training benefits, but not on transfer of those benefits to other tasks. Possible reasons for the general improvement on the near-transfer tasks and the absence of a modulatory role of achievement motivation on transfer-task performance are discussed.     

Microstructure and mechanical behavior of nanostructured composite Cu60Fe40 alloy

In this study, bulk nanostructured composite Cu₆₀Fe₄₀ alloy is prepared by a combustion synthesis technique. The prepared Cu₆₀Fe₄₀ alloy consists of Cu(Fe) solid solution and Fe(Cu) solid solution phases. The large-scaled compositional segregation in the Cu-rich and Fe-rich phases is not observed, respectively. A few micron-sized dendrite (Fe(Cu) solid solution) is embedded into the nanostructured matrix (Cu(Fe) solid solution). The grain size of the matrix is in the range 50–300?nm. The yield and fracture strength of the Cu₆₀Fe₄₀ alloy are 540 and 1050?MPa, respectively, and the fracture strain obtained from the compression test is about 20.9%. The Cu₆₀Fe₄₀ alloy displays notable work hardening in the compressive deformation.     

Do objects in working memory compete with objects in perception?

It is generally assumed that “perceptual object” is the basic unit for processing visual information and that only a small number of objects can be either perceptually selected or encoded in working memory (WM) at one time. This raises the question whether the same resource is used when objects are selected and tracked as when they are held in WM. In two experiments, we measured dual-task interference between a memory task and a Multiple Object Tracking task. The WM tasks involve explicit, implicit, or no spatial processing. Our results suggest there is no resource competition between working memory and perceptual selection except when the WM task requires encoding spatial properties.     

Post-migration Growth Scale for Chinese International Students: Development and Validation

There has been a significant paradigm shift in recent acculturation research from a psychopathological perspective to a resilience framework. However, one indicator of positive adaptation outcomes in acculturation—measurement of personal growth in migration—is lacking. The purpose of this study was to develop and validate a Post-migration Growth Scale (PMGS) for Chinese international students. A 14-item scale was developed through in-depth interviews, item analysis and factor analysis. The scale was initially validated in a sample of 400 mainland Chinese students studying in Hong Kong. Exploratory factor analysis suggested two factors (interpersonal growth and intrapersonal growth), which were cross-validated in an independent sample of Chinese international students in Australia from mainland China (n = 154) by confirmatory factor analysis. The PMGS showed satisfactory internal consistency reliability and concurrent validity. The PMGS can thus be a reliable and valid instrument to measure Chinese international students’ personal growth from overseas study experiences. Limitations were discussed and implications were suggested.

Instrumental lying by parents in the US and China

The practice of lying to one's children to encourage behavioral compliance was investigated among parents in the US (N = 114) and China (N = 85). The vast majority of parents (84% in the US and 98% in China) reported having lied to their children for this purpose. Within each country, the practice most frequently took the form of falsely threatening to leave a child alone in public if he or she refused to follow the parent. Crosscultural differences were seen: A larger proportion of the parents in China reported that they employed instrumental lie‐telling to promote behavioral compliance, and a larger proportion approved of this practice, as compared to the parents in the US. This difference was not seen on measures relating to the practice of lying to promote positive feelings, or on measures relating to statements about fantasy characters such as the tooth fairy. Findings are discussed with reference to sociocultural values and certain parenting‐related challenges that extend across cultures.
