Differences in the micromechanical properties of dendrites and interdendritic regions in superalloys

Statistical analysis of white-light interferometry (WLI) experiments performed on Ni-based single-crystal superalloys (SX) have revealed a different height distribution between the dendritic cores (DCs) and the interdendritic regions (IRs) of the polished samples. The micromechanical property difference is largely ascribed to the uneven distribution of the alloying elements. In this context, possible reasons for this difference are discussed by comparing with different experiment results obtained by previous researchers, and a proposal forecasting the hardness ratio of IRs/DCs is put forward.     

从个体性到社会性:具身研究范式的转向

自20世纪80年代,研究者开始从具身角度看待认知,以具身性为共同话题形成一个与经典离身认知不同的具身研究范式。过去学界主要从个体身体视角理解具身概念,强调具身研究范式的个体性维度。当前学界开始从社会文化视角理解具身概念,强调具身研究范式的社会性维度。这种转变体现了具身研究范式从个体性到社会性的转向。只有将具身的个体性和社会性维度整合起来,从整体构架重新思考具身概念,才能把握其完整内涵。     

Image-processing algorithms for behavior analysis of group-housed pigs

Computational algorithms of image processing were developed and evaluated to select, by motion detection, images of resting artificial pigs and to segment the pigs (mixture of black and white pigs) from their background. Motion detection of the pigs was implemented by detecting interframe differences of postural behavioral images. This algorithm combines the advantages of likelihood ratio method and shading model method and shows a stable performance under noisy and dynamic illumination conditions. Segmentation of the pigs from their background was implemented by employing multilevel thresholding and background reference techniques. The algorithm automatically determines the number of thresholds needed and produces satisfactory segmentation when both black and white pigs with different image intensities are present at the same time (the most complicated situation). The reference background image is updated so that temporal changes in illumination and/or spatial changes of the pen condition have little effect on the performance of image segmentation. The algorithm employs statistical models of the pigs and background and Bayes hypothesis testing to obtain and update the exposed portion of the reference background. Linear filters were used in this process for updating the parameters. These algorithms will serve as essential components for a novel, behavior-based, interactive approach to assess and control thermal comfort of group-housed pigs, which is expected to result in enhanced animal health and well-being.     

Child-oriented family therapy in China: A cross-cultural application of integrative family therapy targeting children aged 4–10

This article describes child-oriented family therapy (COF), a family therapy approach to early psychological and behavioral problems that is widely applied in northern Europe and has been adopted by countries with different cultures, such as Germany and China. This article explains the theoretical background, setting, characteristics, development and effective factors of this method and explores relevant research. In addition, the application of this method in China and reflections on its applicability to families in different cultures are presented. A clinical case is provided to illustrate the core therapeutic principles of COF. Since the application of COF interventions to families with children in Asian cultures remains understudied, the widespread availability of COF and adaptation to local conditions could facilitate training and research achievements in this field.

Open Workplace Climate and LGB Employees' Psychological Experiences: The Roles of Self‐Concealment and Self‐Acceptance

This study explores how an environmental factor (i.e., a perceived open climate) shapes lesbian, gay, and bisexual (LGB) employees' job satisfaction and job anxiety through the mediating role of self‐concealment. It also investigates the moderating role of self‐acceptance. Results from 315 LGB employees supported the conclusion that a perceived open climate for minority sexuality increased job satisfaction and decreased job anxiety. The open climate–job anxiety relationship was mediated by self‐concealment, and both stages of this mediation process were moderated by self‐acceptance. These findings offer useful insights for counselors and managers to help LGB individuals improve their workplace psychological experiences.     

Effects of abusive supervision on employees’ innovative behavior: The role of job insecurity and locus of control

Drawing on the Conservation of Resources Theory by Hobfoll, we examined the relationships between abusive supervision, job insecurity, locus of control, and employees’ innovative behavior. Using self‐reported data collected from employees among four enterprises in China (N = 641), we found that abusive supervision was positively correlated with job insecurity. In contrast, both job insecurity and abusive supervision were negatively correlated with employees’ innovative behavior, with the impact of abusive supervision on innovative behavior being mediated by its effect on job insecurity. Having an external locus of control that served as a buffering factor for employees, mitigating the relationship between abusive supervision and job insecurity. These findings complement the existing research on the impacts of abusive leadership, providing practical information for enterprises on how to enhance levels of innovation and vitality among employees.     

Teacher's Encouragement on Creativity,Intrinsic Motivation,and Creativity: The Mediating Role of Creative Process Engagement

Drawing on Dewey's pragmatic perspective on talent cultivation and previous research on promoting employee creativity in industry, this study investigates student creativity performance in relation to teacher's encouragement, intrinsic motivation, and creative process engagement. Based on survey data collected from 140 vocational high school students who participated in a nation‐wide contest in Taiwan, path analyses were performed using structure equation modeling techniques. The results indicate that both teacher's encouragement and intrinsic motivation have a significant, although indirect, effect on student creativity, and that creative process engagement, as opposed to teacher encouragement or intrinsic motivation, has a direct and significant mediating effect on student creativity. This finding is in partial agreement with prior research which reports student creativity is positively associated with teacher encouragement and intrinsic motivation, highlighting the mediating role of creative process engagement in facilitating student creative performance.     

Prolonged Separation and Reunification among Chinese Immigrant Children and Families: An Exploratory Study

The present study explored the lived experiences of Chinese immigrant parents in New York City who went through prolonged separation and faced challenges after reunification in the United States. The study assessed their attitudes, perceptions, and reactions to the separation and reunification process to gain better understanding of the ways prolonged separation and reunification impact on child development and family wellbeing. A phenomenological research approach was used to study qualitatively the narrative data from in-depth interviews. The analytical process was based on data immersion, coding, sorting codes into themes, and comparing the themes across interviews. The sample included 18 Chinese immigrant families who had sent their American-born children to China for rearing and reunited with their children within the past 5 years. Data analyses revealed specific themes that included reasons for separation, parenting methods, child’s initial adjustment, behavior, and family relationship, child’s social, emotional, and academic challenges, parental stress and challenges, and recommendations for services. This study contributed to our knowledge of prolonged separation, a common practice among a vulnerable, hard-to-reach immigrant population. It shed light on specific needs of Chinese immigrant families by examining closely the unique circumstances pertaining to prolonged separation, parenting practice, and related family challenges. An understanding of the approaches these families adopt to cope with life challenges may help inform practitioners in formulating service strategies for these families. Specific assessments in child-care, education, and health care settings are essential to prompt immediate follow-up and intervention when needed.     

网络学习中学习者个人特征对学习投入的影响:一个有调节的中介效应模型

以参与网络课堂的387名大学生为被试,考察自我效能感、内隐智力信念和动机调节等学习者特征对网络学习环境中学习投入的影响及其作用机制。结果表明:(1)网络学习者的自我效能感、动机调节、内隐智力信念均能正向预测学习投入;(2)动机调节在自我效能感和学习投入的关系中起部分中介作用;(3)"自我效能感→动机调节→学习投入"这一中介效应的后半路径受到学习者内隐智力信念的调节。相较于智力实体论者,动机调节的中介效应在智力增长论者中更强。
