认知诊断模型中项目水平模型比较统计量的健壮性

使用模拟研究方法比较了以往研究中提出的基于观察信息矩阵、三明治矩阵的Wald（分别表示为W_Obs、W_Sw）、似然比（Likelihood Ratio）统计量以及新提出的基于经验交叉相乘信息矩阵的Wald统计量（W_XPD）在模型——数据失拟条件下进行项目水平上模型比较时的表现。结果显示：（1）W_Sw的一类错误控制率有很强的健壮性。（2）W_XPD在Q矩阵错误设定的大多数条件下的表现优于W_Sw。结论：模型—数据拟合良好时可以使用W_Sw进行项目水平上的模型比较,当模型与数据失拟时W_XPD可能是更好的选择。     

6~8岁儿童公平行为的内在动机：社会信号的作用

公平行为是个体对自己或别人不偏不倚的行为,存在本质公平与表现公平。本质公平,即个体本身渴望公平,能够依据某种公平原则做出公平行为;表现公平,即个体在行为上做出公平的表现而实质并非来自本身的意愿。研究1选取270名6~8岁儿童,采用资源分配任务考察儿童在有无社会信号作用下表现公平行为的发展特点,研究2选取300名6~8岁儿童,采用抛硬币任务来考察儿童是否会用公平程序来掩盖其不公平行为。结果表明：(1)有无社会信号条件对儿童公平行为存在显著影响,并存在显著的年龄差异。有社会信号条件下,儿童更多选择公平行为,无社会信号条件下,儿童更多选择对自己有利的不公平分配。(2)儿童选择通过抛硬币的方式来获取奖品的人数随着年龄增长显著上升,抛硬币的儿童报告自己得到好的奖品的概率显著多于得到不好奖品的概率。结论：社会信号作用下儿童更多会做出表现公平而非本质公平。     

An activist religiosity? Exploring Christian support for the Occupy movement

While Christian involvement in progressive social movements and activism is increasingly recognized, this literature has rarely gone beyond conceptualising religion as a resource to consider instead the ways in which individual activists may articulate their religious identity and how this intersects with the political. Based on ten in-depth interviews with Christian supporters of the London Occupy movement, this study offers an opportunity to respond to this gap by exploring the rich meaning-making processes of these activists. The article suggests that the location of the Occupy camp outside St Paul’s Cathedral was of central importance in bringing the Christian Occupiers’ religio-political identities to the foreground, their Christianity being defined in opposition to that represented by St Paul’s. The article then explores the religio-political meaning-making of the Christian Occupiers and introduces the term ‘activist religiosity’ as a way of understanding how religion and politics were articulated, and enacted, in similar ways. Indeed, religion and politics became considerably entangled and intertwined, rendering theoretical frameworks that conceptualise religion as a resource increasingly inappropriate. The features of this activist religiosity include post-institutional identities, a dislike of categorisation, and, centrally, the notion of ‘doings’—a predominant focus on engaged, active involvement.     

The relationship of anthropometric measurements with psychological criteria in female athletes

Sports and exercise settings as well as other socio-cultural environments emphasize a thin and physically fit female body. However, there is a clear need for a better understanding of the physical and psychological correlates of social physique anxiety and body image dissatisfaction in female athletes. This study aimed to examine the association of the social physique anxiety, body image satisfaction, and personality with the anthropometric measurements in female college athletes according to their sport type using the Co-Plot technique. The sample included 63 female athletes ranging in age from 18 to 26. Results of the Co-Plot analysis revealed a significant association among social physique anxiety, personality and anthropometric measurements. This means that certain physical measurements may lead to greater social physique anxiety and body image dissatisfaction in female athletes. It was found that females having higher levels of social physique anxiety and thus, lower levels of body image satisfaction may be less emotionally stable and more negatively perfectionist. In conclusion, the results of the present study provided evidence to the claim that both physical self-perception and anthropometric measurements may be closely associated with psychological criteria in female athletes.     

Virtual voices: social support and stigma in postnatal mental illness Internet forums

Many women with postnatal mental illness do not get the treatment they need and this is often because stigma prevents disclosure. The purpose of this study was to explore online social support for postnatal mental illness, how women experience stigma and potential disadvantages of using Internet forums. Interviews were conducted with fifteen participants who had suffered postnatal mental illness and had used forums. Systematic thematic analysis identified common themes in relation to social support, stigma and disadvantages of using forums. Most women felt they benefited from visiting forums by developing a shared understanding and discourse about their illness. Findings suggest future research should investigate if women benefit from using online social support provided by forums, if use challenges stigma and further explore potential concerns about using forums.     

Hiding behind a mask? Cultural intelligence,knowledge hiding,and individual and team creativity

Culturally diverse colleagues can be valuable sources for stimulating creativity at work, yet only if they decide to share their knowledge. Drawing on the social exchange theory, we propose that cross-cultural interactions among individuals from different national backgrounds can act as a salient contingency in the relationship between knowledge hiding and creativity (individual and team). We further suggest, based on the social categorization theory (e.g., the categorization process of “us” against “them” based on national differences), that cultural intelligence enhances the likelihood of high-quality social exchanges between culturally diverse individuals and, therefore, remedies the otherwise negative relationship between individual knowledge hiding and individual creativity. Two studies using field and experimental data offer consistent support for this argument. First, a field study of 621 employees nested among 70 teams revealed that individual knowledge hiding is negatively related to individual creativity and that cultural intelligence moderates the relationship between knowledge hiding and creativity at an individual level. A quasi-experimental study of 104 international students nested in 24 teams replicated and extended these findings by implying that individual knowledge hiding is also negatively related to team creativity. We discuss the implications for practice and future research.     

Social support coping style predicts women’s cortisol in the laboratory and daily life: the moderating role of social attentional biases

Background and Objectives: Social stress and associated coping responses can profoundly influence women’s stress physiology and health. Implicit social attentional biases can also influence psychological and physiological stress responses. The purpose of this study was to explore whether a coping style characterized by greater use of social support predicts indices of cortisol activity in laboratory and daily life contexts among female university students. We hypothesized that the relation of this coping style to cortisol activity would be moderated by women’s attentional biases.

Methods: Seventy-four women (M_age?=?19.44, range: 17.8–27.8, 64% White) completed an interpersonal stress task and an attentional bias task in the lab, along with a self-report coping inventory. Participants provided five saliva samples during the lab protocol, followed by three saliva samples per day for three consecutive weekdays. Outcome measures included cortisol response to lab tasks (AUCg), diurnal cortisol slope, diurnal AUCg, and cortisol awakening response (CARi).

Results: A coping style characterized by greater use of social support predicted lower lab AUCg and lower, flatter average diurnal cortisol slope for women with attentional avoidance compared to women with attentional vigilance (ps?<?.05).

Conclusions: Responding to stress by using social support is linked to lower cortisol responses to social stress and diurnal cortisol activity for women with implicit avoidance of social threat cues.     

Differential Influence of Social Support in Emerging Adulthood Across Sources of Support and Profiles of Interpersonal and Non-Interpersonal Potentially Traumatic Experiences

Social support is protective against the negative effects of trauma, yet how these effects vary across sources of support and patterns of trauma exposure has not been examined. High co-occurrence exists among different types of trauma across domains and ages, yielding patterns of trauma exposure that may affect social support. This study identified profiles of potentially traumatic events (PTEs) experienced by 252 college students and examined the relationships between social support and mental health across these profiles. Five profiles emerged: “Non-Interpersonal Trauma Exposure,” “Adult Intimate Partner Violence,” “Poly-trauma Exposure,” “Low Trauma Exposure,” and “Childhood Family Violence.” The link between social support and adjustment differed across profiles. Family support was valuable for promoting resilience across patterns of PTEs. Friend and romantic partner support were related to lower mental health problems. Support from family and friends is particularly valuable in the context of adult intimate partner violence and childhood family violence.     

Seeing Is Believing: Using Video Feedback in Cognitive Therapy for Social Anxiety Disorder

Distorted negative self-images and impressions appear to play a key role in maintaining Social Anxiety Disorder (SAD). In previous research, McManus et al. (2009) found that video feedback can help people undergoing cognitive therapy for SAD (CT-SAD) to develop a more realistic impression of how they appear to others, and this was associated with significant improvement in their social anxiety. In this paper we first present new data from 47 patients that confirms the value of video feedback. Ninety-eighty percent of the patients indicated that they came across more favorably than they had predicted after viewing a video of their social interactions. Significant reductions in social anxiety were observed during the following week and these reductions were larger than those observed after control periods. Comparison with our earlier data (McManus et al., 2009) suggests we may have improved the effectiveness of video feedback by refining and developing our procedures over time. The second part of the paper outlines our current strategies for maximizing the impact of video feedback. The strategies have evolved in order to help patients with SAD overcome a range of processing biases that could otherwise make it difficult for them to spot discrepancies between their negative self-imagery and the way they appear on video.     

Cyberbullying Involvement of Adolescents with Low Vision Compared to Typical Adolescents,as Related to Perceived Social Support

This study examined adolescents with low vision (LV) compared to students without disabilities regarding their cyberbullying experiences, as related to perceived social support. Sample consisted of 407 students (61 with LV) who completed self-reported questionnaires. Findings revealed that students with LV are using the computer and the Internet as much as the typical students, but students with LV had less frequent Internet interactions with friends. Students with LV reported being more involved in cyberbullying as cybervictims, cyberperpetrators, cyberwitnesses, knowing someone and telling their online experience to another, and having lower social support compared to students without disabilities. Students with LV are more willing to report and to share their online experiences with another person. The findings add to our knowledge about students’ experiences of cyberbullying and suggest implementing effective coping strategies programs to raise the awareness of cyberbullying risky behavior.
