在内科临床中落实生物心理社会医学模式

社会心理因素与内科疾病的发生、发展和治疗效果关系密切,临床工作中忽视社会心理因素的作用可能导致严重后果。内科医生应积极拓展自身的知识技能,继而把对社会心理因素的重视落在实处,体现在病历中。完整的病史采集又需要加强医患沟通,如此才能真正发现和解决患者的社会心理问题。     

整体护理与新医学模式

整体护理作为当代护理的基本工作模式和护理学发展的基本趋势,是与生物心理社会医学模式的确立直接相联系的。在临床护理中,落实新医学模式,是推行整体护理所必需的。在整体护理中落实新医学模式应从转变护理人员观念、整体护理规范化、改变护理队伍的知识和技能结构、提供护士职业道德水平等方面做起。

Utilizing response times in cognitive diagnostic computerized adaptive testing under the higher-order deterministic input,noisy ‘and’ gate model

Methods of cognitive diagnostic computerized adaptive testing (CD-CAT) under higher-order cognitive diagnosis models have been developed to simultaneously provide estimates of the attribute mastery statuses of examinees for formative assessment and estimates of a latent continuous trait for overall summative evaluation. In a typical CD-CAT environment, examinees are often subject to a time limit, and the examinees’ response times (RTs) for specific test items can be routinely recorded by custom-made programs. Because examinees are individually administered tailored sets of test items from the item pool, they may experience different levels of speededness during testing and different levels of risk of running out of time. In this study, RTs were considered during the item-selection procedure to control the test speededness and the RTs were treated as useful information for improving latent trait estimation in CD-CAT under the higher-order deterministic input, noisy ‘and’ gate (DINA) model. A modified posterior-weighted Kullback–Leibler (PWKL) method that maximizes the item information per time unit and a shadow-test method that assembles a provisional test subject to a specified time constraint were developed. Two simulation studies were conducted to assess the effects of the proposed methods on the quality of CD-CAT for fixed- and variable-length exams. The results show that, compared with the traditional PWKL method, the proposed methods preserve a lower risk of running out of time while ensuring satisfactory attribute estimation and providing more accurate estimates of the latent trait and speed parameters. Finally, several suggestions for future research are proposed.     

A Social Network Analysis of Friendship and Spiritual Support in a Religious Congregation

Religious congregations are social settings where people gather together in community to pursue the sacred (Pargament, 2008). Such settings are important to understand as they provide a context for individuals to develop relationships, share ideas and resources, and connect individuals to larger society (Todd, 2017a). Yet, research to date has not deeply examined the inherently relational nature of religious congregations. Thus, in this study, we used social settings theory (Seidman, 2012; Tseng & Seidman, 2007) to develop and test hypotheses about relationships within one Christian religious congregation. In particular, we used social network analysis to test hypotheses about relational activity, popularity, and homophily for friendship and spiritual support types of relational links. Our findings demonstrate how relational patterns may be linked to participation in congregational activities, occupying a leadership role, a sense of community and spiritual satisfaction, stratification, socialization, and spiritual support. Overall, this advances theory and research on the relational aspects of religious congregations, and more broadly to the literature on social settings. Limitations, directions for future research, and implications for theory and religious congregations also are discussed.     

Partner–objectification in romantic relationships: A dyadic approach

The present study investigated the relationship between the objectification of one's romantic partner (partner–objectification) and relationship quality using 221 heterosexual couples. Controlling for relevant covariates, actor–partner interdependence models revealed no partner effects but multiple actor effects. First, men who objectified their partners more had lower levels of relationship commitment and relationship satisfaction, and perceived higher quality alternatives to the relationship. Second, women who objectified their partners more had lower levels of relationship satisfaction themselves. Third, relationship duration marginally moderated the association between partner–objectification and relationship commitment, with partner–objectification negatively linked to one's own relationship commitment in relationships of shorter durations, but not when relationship durations were longer. Implications for an investment model and romantic relationship objectification are discussed.     

Loneliness,eating, and body mass index in parent–adolescent dyads from the Family Life,Activity, Sun,Health, and Eating study

Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.     

Understanding the impact of heterogeneous rider preferences on a shared autonomous vehicle system

In a ride pooling system, riders may have varied behaviors in seeking pooled or non-pooled rides. It is important to understand the effect of these rider behaviors on the system performance in order to formulate policies to guide ride pooling implementation. Existing literature modeling ride pooling systems using agent-based models only considers the extreme cases in which riders either all participate or not participate in pooling. However, the pooling behaviors could be more complex. This study segments the rides in the system into five types (non-pooling only, non-pooling preferred, indifferent, pooling preferred, and pooling only). We use an agent-based model to simulate these preferences in a system of pooled autonomous vehicles. We use mixture experiments to vary the proportion of riders within these five types and build models to study the interactions among the rider types in terms of the system’s service quality and environmental performance. The results show that higher service level is achieved when all riders in the system are open to pooling, with 30% of pooling only riders and 70% of pooling preferred or indifferent riders providing the maximum value. The results can help formulate incentives and policies to promote ride pooling participation to improve ride pooling system performance.     

疼痛背景下时距知觉的变化

时距知觉指对数百毫秒到数个小时时长的知觉, 是日常生活中许多活动的基础。时距知觉受到相当多因素的影响, 如唤醒、注意、动机等。疼痛是一种多维度的心理及生理现象, 包含有感觉分辨、情绪动机、认知评价三个成分。近期研究证明时距知觉会在疼痛背景下发生改变。疼痛背景下时距知觉的相关研究主要涉及三个方面：(1)健康被试对疼痛面孔的时距知觉; (2)实验室诱发疼痛对健康被试时距知觉的影响; (3)临床疼痛患者的时距知觉变化。探索疼痛背景下时距知觉的变化, 可以为理解疼痛的发生发展机制以及时间知觉的机制提供一个新视角。
