Microstructural features of phase transformation in a binary Pd–Si metallic glass

Glassy ribbons of Pd–Si alloys were prepared by a combination of melt spinning and flux treatment. The crystallization behaviour of a Pd₈₁Si₁₉ glassy alloy was studied through isothermal annealing at temperatures ranging lower than the glass-transition temperature T _g to around the onset of crystallization. The evolution of microstructures arising from isothermal annealing was investigated by X-ray diffraction (XRD) and (high-resolution) transmission electron microscopy ((HR)TEM). XRD spectra showed that, after the sample was annealed at a sub-T _g temperature, its first diffraction peak was split into two overlapping broad peaks. TEM analysis revealed the formation of a spherical, particle-like glassy phase embedded in the glassy matrix together with a finely connected network morphology within both. Combining these observations with compositional analysis suggested that phase separation had taken place during sub-T _g annealing. When the glassy alloy was annealed at temperatures higher than T _g, nanocrystalline structures, composed of Pd₃Si and Pd phases plus a Pd₉Si₂ phase with a lamellar structure, was formed.     

Complicating Counterspaces: Intersectionality and the Michigan Womyn's Music Festival

The counterspaces framework articulated by Case and Hunter (2012), follows from community psychology's long‐standing interest in the potential for settings to promote well‐being and liberatory responses to oppression. This framework proposes that certain settings (i.e., “counterspaces”) facilitate a specific set of processes that promote the well‐being of marginalized groups. We argue that an intersectional analysis is crucial to understand whether and how counterspaces achieve these goals. We draw from literature on safe spaces and present a case study of the Michigan Womyn's Music Festival (Michfest) to illustrate the value of an intersectional analysis and explore how these processes operate. Based on 20 in‐person interviews, 23 responses to an online survey, and ethnographic field notes, we show how Michfest was characterized by a particular intersection of identities at the setting level, and intersectional diversity complicated experiences at the individual level. Moreover, intersectional identities provided opportunities for dialogue and change at the setting level, including the creation of counterspaces within counterspaces. Overall, we demonstrate the need to attend to intersectionality in counterspaces, and more broadly in how we conceptualize settings in community psychology.     

从青少年学生的评价看教师的人格结构

本研究以班为单位,要求1594名大、中、小学生采用《青少年学生评价教师人格特质形容词捡核表》对自己理想中的教师人格特质进行评定,结果显示学生们对教师人格特质的评价维度是：高尚／进取、慈爱/公正、客观／求真、外向／开朗、退缩/粗暴、内向／怪异、损人俐己,前四个维度是学生们喜欢的,后三个维度是学生们不喜欢的。学生们对教师人格的评价存在着年龄、性别和学科上的差异。

异性拒绝对大学生择偶行为的长期影响:基于社会计量器理论的探讨

运用问卷调查法以339名大学生为研究对象,基于社会计量器理论探讨异性拒绝经历和择偶价值感对大学生择偶行为的长期影响。研究发现:(1)女大学生的择偶标准显著高于男大学生,男大学生的择偶行为倾向略高于女大学生;(2)异性拒绝经历与择偶价值感、择偶标准、择偶行为倾向呈负相关,择偶价值感与择偶标准、择偶行为倾向呈显著正相关;(3)异性拒绝经历可以显著负向预测大学生的择偶行为,择偶价值感在异性拒绝经历对大学生择偶行为影响中起部分中介作用,但其发挥作用的方式存在性别差异。这一结果表明,择偶价值感是一种重要的缓冲因素,可以在一定程度上缓解异性拒绝给大学生择偶行为带来的负面影响。     

Trust in God: The COVID-19 Pandemic's Impact on Religiosity in China

Emerging research shows the COVID-19 pandemic has made substantial changes to the religious climate of several nations. Surprisingly, China, the outbreak center of the pandemic, has been scarcely researched. Our study investigates how the COVID-19 pandemic has evoked new religious disaster responses and provided psychological coping mechanisms during the pandemic. We also explore how the pandemic explains surprising rates of religiosity in China. Scholars have long proposed that religious resurgence in China has been a result of individuals seeking stability in turbulent times. We bridge parallel Literatures in these areas and treat the pandemic as a natural experiment for evaluating religious behavior over time as conditioned by heightened risk perception. Utilizing a difference-in-differences estimation strategy with panel data, our study reveals that the pandemic has led to a significant increase in religiosity in China, particularly in religious areas most affected by the pandemic. We propose that even in a highly regulative religious environment, with most of its population being religiously unaffiliated, religion is a significant resource for coping in China. We take an innovative approach to demonstrate this by utilizing online search data. Our research speaks to the sociology of religion, the social psychology of risk perception, and makes application to emerging research on the unfolding COVID-19 pandemic.     

HIV/AIDS and Psychosis: Needs,Challenges, and Support of Affected Mothers

Little is known about parenting in the context of HIV and psychosis, two co-existing conditions affecting many mothers in South Africa. In this study a mixed methods approach was used to firstly do qualitative investigation of the illness and parenting experiences of a case group of mothers living with HIV/AIDS and psychosis (n?=?41). Secondly, the support networks of this group are compared with a control group of mothers with HIV/AIDS without psychosis (n?=?44). Integrating qualitative and quantitative data highlight the emotional and physical disruption experienced by the case group that contribute to dysfunctional mother–child interactions. This experience may be detrimental to the child’s well-being and formation of attachment relationships. Healthy support networks may buffer these adversities. The availability of support figures is similar between the groups, but the case group has less spousal support. Paranoia associated with the case group predicted fewer support figures, thus emphasizing the vulnerability of this group of mothers and children.
