A Cultural Analysis of China’s Scientific Brain Drain: the Case of Chinese Immigrant Scientists in Canadian Academia

While the booming market and policy incentives of China are reversing the pattern of talent flow across the Pacific, a large proportion of the mainland Chinese immigrant scientists currently in Canadian academia have decided not to return home; meanwhile, their interactions with China in terms of brain circulation are not extensive overall. This study attempts to explore the key factors for the paradox of China’s scientific brain drain through the lens of culture, drawing on data mainly from in-depth interviews with 14 mainland Chinese immigrant scientists in Canadian academia. The theoretical framework derives from the models of cultural negotiation (Sakamoto 2001) and bidimensional acculturation (Berry, Appl Psychol 46: 5–34, 1997). Data analysis reveals that cultural factors override everything else in shaping the leave–stay decision and brain exchange behavior of these Chinese scientists, who have gone through a cultural negotiation and construction process. With a transformed perspective, these academic migrants hold firmly the new culture’s beliefs, attitudes, and behaviors; therefore, the work styles, notions, and ethics of their counterparts in China have cultural limitations and are incongruent with their practice in Canada. Meanwhile, they have been significantly influenced by Chinese cultural values, notably group orientation, hierarchy loving, self-abasement, harmony seeking, face saving, etc. The findings should shed some light on public policies aiming to realize the full value of top talents for the benefits of China, Canada, and beyond.     

成人依恋对病理性网络使用的影响:社交自我效能感和孤独感的中介作用

为探讨成人依恋影响病理性网络使用(PIU)的内在机制,采用自陈式问卷调查了483名大学生,通过结构方程模型和bootstrap法考察了社交自我效能感和孤独感在成人依恋与PIU关系中的中介作用。结果表明:(1)孤独感在依恋焦虑和依恋回避对PIU的影响中起中介作用;(2)社交自我效能感和孤独感在依恋回避对PIU的影响中起链式中介作用。研究结论:成人依恋通过社交自我效能感和孤独感的中介作用影响PIU,且依恋焦虑和依恋回避两个维度的中介机制有差异。     

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.     

情绪面孔的意识神经相关物及其无意识自动加工：来自事件相关电位的证据

意识的神经相关物尚有争议, 且个体能否无意识自动检测视觉环境变化尚不清楚。本研究采用非注意视盲范式操控视觉意识, 并引入具有社会信息的情绪面孔, 探讨意识的神经相关物以及视觉意识与自动检测变化机制的关系。在A阶段, 部分被试对任务无关的情绪面孔处于无意识水平; 在B阶段, 所有被试对任务无关的情绪面孔处于意识水平; 在C阶段, 所有被试对任务相关的情绪面孔处于意识水平。结果显示, 任务无关的情绪面孔的意识过程诱发视觉意识负波(visual awareness negativity, VAN)、晚期正成分(late positivity, LP)和晚期枕区正成分(late occipital positivity, LOP)。此外, 无意识的情绪面孔能诱发视觉失匹配负波(visual mismatch negativity, vMMN), 且其幅值不受意识影响, 但是受任务相关性调制。这些结果提示对情绪面孔的视觉意识在不同的时间进程上有不同的ERP指标——VAN反映早期知觉经验, 而LP和LOP反映晚期意识过程, 而且面孔情绪信息的自动加工独立于视觉意识, 但是受视觉注意调制。     

物体表征强度对基于动态物体的注意的影响

基于物体的注意已得到许多静态物体实验的证实, 然而, 对注意分配如何受动态物体影响的研究较少, 存在提示物体假设和动态更新假设两种观点。提示物体假设认为基于物体的注意由最初的物体决定, 而动态更新假设则认为由变化之后的物体决定。动态物体的注意研究还发现了即时物体效应, 即注意基于新物体进行。对于物体变化时注意究竟基于旧物体还是新物体, 新旧物体的相对物体表征强度在其中起决定作用; 当提示物体表征较强时表现为提示物体(即旧物体)决定注意分配, 而当即时物体表征较强时表现为即时物体(即新物体)决定注意分配。相对物体表征强度的概念对理解物体动态变化情况下基于物体的注意的分配以及解决相关理论之冲突可能有重要作用。     

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.
