青少年早期同伴拒绝、同伴侵害与抑郁的关系：交叉滞后分析

采用间隔1年的追踪设计,使用结构方程建模对1068名青少年早期个体的同伴拒绝、同伴侵害与抑郁间的关系进行交叉滞后分析。结果发现,（1）在不同时间点上,同伴拒绝、同伴侵害和青少年抑郁之间存在显著正相关;（2）先前的抑郁水平对随后个体遭受的身体侵害和关系侵害均有显著预测作用,而先前的同伴侵害不能显著预测随后青少年的抑郁水平。抑郁对同伴拒绝、以及同伴拒绝对抑郁的预测作用均不显著。（3）同伴拒绝、同伴侵害与抑郁间的关系具有跨性别的一致性。这表明,青少年早期同伴侵害和抑郁间存在单向预测关系,抑郁导致同伴侵害。     

Perceived stigma of caregivers: Psychometric evaluation for Devaluation of Consumer Families Scale

Background/Objective: The Devaluation of Consumer Families Scale (DCFS) is commonly used to measure perceived stigma towards family members of people with mental illness. However, its factorial structure has never been confirmed using confirmatory factor analysis (CFA). This study aimed to test the psychometric properties of the DCFS Taiwan version (DCFS-TW). Method: Family caregivers (N=511) completed the DCFS-TW (97 completed the DCFS again after 2 to 4 weeks) and other instruments. CFA, test-retest reliability, internal consistency, concurrent validity, and known-group validity were analyzed. Results: The three-factor structure of the DCFS-TW performed better than the one-factor structure. Test-retest reliability (r = .66) and internal consistency were satisfactory (α = .85); concurrent validity (absolute r = .20 to .58) was acceptable; known-group validity was supported by the significantly different DCFS-TW scores in clinical characteristics (had been vs. had not been hospitalized; had been vs. had not been compulsorily admitted). Conclusions: The DCFS-TW has decent psychometric properties and is suitable for health professionals to measure perceived stigma towards family members of people with mental illness.     

Citizenship’s tangled web: Associations,gaps and tensions in formulations of European youth active citizenship across disciplines

Abstract

How does academic literature across various disciplines conceptualize and empirically address active citizenship? What are the potential benefits and dangers of dominant epistemological and ideological perspectives on ‘good citizenship’? Our paper engages with these questions by drawing on literature across 12 disciplines. We used textual analysis software T-LAB to quantify and visualize co-occurrences, word associations and thematic clusters in the abstracts of 770 texts gathered by eight country teams and original in-depth qualitative analyses of ideological positions and discourses taken up in a selection of key texts across the corpus. Our paper elaborates the findings: that many of the key themes surrounding young people and citizenship in the literature share little or no connection with European citizenship; that there is a significant gap in the literature on young European citizens; and that studies connected to internal, status-based factors connected to citizenship are far more prevalent than those examining external, practice-based factors or dissidence and dissent. Our conclusions examine the potential normative implications of the disjuncture between dominant conceptions and critical accounts of youth active citizenship.     

围手术期抗菌药物合理使用与药品费用的相关性分析

探索性因素分析因子抽取方法的比较

探索性因素分析决定因子抽取的方法主要有Bartlett法、K1原则、碎石检验法、Aaker原则、PA、MAP等六种,通过对样本1的395名大学生的学习过程问卷调查获得真实数据,运用这六种方法进行因素分析分别抽取7、4、2、4、3、2个因子;应用样本2的383名大学生的问卷调查数据进行验证性因素分析,结果显示,碎石检验方法与MAP方法抽取的二因素模型更理想。研究表明,因子抽取需兼顾“简约性原则”与“完备性原则”,同时要根据一定的理论建构、专业知识和经验来决定因子数。     

Role of amygdala-prefrontal cortex circuitry in regulating the expression of contextual fear memory

The basolateral amygdala (BLA) and medial prefrontal cortex (mPFC) are inter-connected regions involved in fear memory expression. The reciprocal nature of projections between these areas differs along the rostrocaudal extent of BLA. This study investigated the role of functional interactions between BLA and the prelimbic (PL) subregion of mPFC in mediating contextual fear memory. Freezing served as the measure of conditioned fear. Experiments 1–3 examined the effects of left, right or bilateral infusion of bupivacaine into anterior BLA (aBLA), posterior BLA (pBLA) or PL on fear memory expression. Reversible inactivation of left, right or bilateral aBLA impaired fear memory expression. Bilateral inactivation of pBLA or PL also disrupted the expression of fear memory, although left or right inactivation alone had no significant effects in either region. Experiment 4 examined the effects of functionally disconnecting pBLA and PL on contextual fear memory by infusing bupivacaine unilaterally into pBLA and PL in the ipsilateral or contralateral hemisphere. Fear memory expression was impaired by asymmetric inactivation of pBLA and PL; however, a similar effect was also observed with symmetric inactivation of these regions. Bupivacaine infusion did not affect behavior in the open field, likely ruling out non-specific effects of inactivation on innate fear and locomotor activity. These results demonstrate different roles for rostral and caudal BLA in mediating the expression of contextual fear memory. They also raise the possibility that pBLA–PL circuitry is involved in subserving fear memory expression via complex processing mechanisms, although further research is needed to confirm this preliminary finding.     

Attention during visual secondary tasks in driving: Adaptation to the demands of the driving task

Visual attention in driving with visual secondary task is compared for two visual secondary tasks. N = 40 subjects completed a 1 h test drive in a motion-base driving simulator. During the drive, participants either solved an externally paced, highly demanding visual task or a self paced menu system task. The secondary tasks were offered in defined critical and non-critical driving situations. Eye movement behavior was analyzed and compared for both tasks. Before starting the secondary tasks, eye movement behavior shows a smaller standard deviation of gaze as well as longer fixation durations for both tasks. The comparison between the two tasks indicates that drivers use the possibilities the self paced task offers: during the secondary task, they monitor the driving scene with longer fixations and show a greater standard deviation of gaze position. Furthermore, independently of the type of secondary task, drivers adapt their eye movement behavior to the demands of the situation. In critical driving situations they direct a larger proportion of glance time to the driving task. Last, the relation between glance behavior and collisions is analyzed. Results indicate that collisions go together with an inadequate distribution of attention during distraction. The results are interpreted regarding the attentional processes involved in driving with visual secondary tasks. Based on the similarities and differences between the two secondary tasks, a cognitive approach is developed which assumes that the control of attention during distraction is based on a mental situational model of the driving situation.
