正常高值血压者血压昼夜节律与靶器官损害的相关性研究

探讨正常高值血压昼夜节律与靶器官损害的相关性。入选正常高值血压者150例,其中杓型组72例,非杓型组78例,60例正常血压者为对照组。检测尿白蛋白排泄率（UAE）、颈动脉内膜中层厚度（IMT）和左心室重量指数（LVMI）。杓型组和非杓型组UAE、IMT、LVMI高于对照组（P＜0．01）。非杓型组UAE、IMT、LVMI高于杓型组（P＜0．05）。正常高值血压人群已出现靶器官损害,血压昼夜节律异常与早期靶器官损害密切相关。     

Attachment styles and clinical correlates in people at ultra high risk for psychosis

Evidence suggests that attachment styles may influence subclinical psychosis phenotypes (schizotypy) and affective disorders and may play a part in the association between psychosis and childhood adversity. However, the role of attachment in the initial stages of psychosis remains poorly understood. Our main aim was to describe and compare attachment styles in 60 individuals at ultra high risk for psychosis (UHR) and a matched sample of 60 healthy volunteers (HV). The HV had lower anxious and avoidant attachment scores than the UHR individuals (p < .001). Sixty-nine percentage of the UHR group had more than one DSM-IV diagnosis, mainly affective and anxiety disorders. The UHR group experienced more trauma (p < .001) and more mood and anxiety symptoms (p < .001). Interestingly, in our UHR group, only schizotypy paranoia was correlated with insecure attachment. In the HV group, depression, anxiety, schizotypy paranoia, and social anxiety were correlated with insecure attachment. This difference and some discrepancies with previous studies involving UHR suggest that individuals at UHR may compose a heterogeneous group; some experience significant mood and/or anxiety symptoms that may not be explained by specific attachment styles. Nonetheless, measuring attachment in UHR individuals could help maximize therapeutic relationships to enhance recovery.     

高中生感恩与心理一致感的关系:积极情感与积极应对的中介效应

采用整群抽样法对449名高中生进行了感恩,积极情感,积极应对以及心理一致感的测量,通过结构方程模型分析了积极情感与积极应对在感恩与心理一致感之间的中介作用,结果如下:(1)感恩既对心理一致感有直接预测作用,占总效应的46%,又可以通过积极情感与积极应对间接作用于心理一致感,占总效应的54%,总中介效应要大于直接效应;(2)感恩到积极应对作用路径的差异值临界比(CRD)存在性别差异,男生的路径系数(γ=.43,p.01)显著高于女生(γ=-.01,p.05)。     

The effects of a high-probability instruction sequence and response-independent reinforcer delivery on child compliance

We compared the effects of a high-probability (high-p) instruction sequence and a fixed-time (FT) schedule of reinforcement on the compliance of 2 typically developing children. A multielement experimental design with a reversal component was implemented according to a multiple baseline across participants arrangement. Both the high-p and FT conditions resulted in increased compliance for both participants during the multielement sessions. These results suggest that it may be possible to increase compliance without a response requirement of the type arranged in the high-p instruction sequence.     

The prevention of anxiety and depression in children from disadvantaged schools

A randomised controlled trial evaluated the Aussie Optimism Program in preventing anxiety and depression. Grade 7 students (n = 496) from disadvantaged government schools in Perth Western Australia, participated. Six schools were randomly assigned to Aussie Optimism and six schools received their usual health education lessons. Students completed questionnaires on depression, anxiety, attribution style, and social skills. Parents completed the Child Behavior Checklist. No significant group effects were found for student-reported data. Parents of intervention group only students reported reductions in internalizing problems at post-test. No follow-up group effects were significant. Students and teachers found the program acceptable.     

Do Guns in the Home Predict Gender and Relationship Attitudes? An Exploratory Study

This study explores the potential relationship of guns in students’ homes with attitudes indicative of tolerance of violence, negative attitudes toward women and their roles, and attitudes suggestive of myths regarding sexual assault. Seniors in Kentucky high schools whose families possessed guns (n = 1,749) produced higher scores on scales measuring these variables as well as on scales of relationship dependency and religious involvement than seniors whose families did not own guns (n = 912). Students whose families owned more than 10 guns tended to score highest on these measures compared with students whose families owned no guns or a few guns. Because of lower effect sizes, these significant associations require further investigation.

早期目标血糖管理下严重脓毒症患者HMGB1的变化及其临床意义

探讨早期目标血糖管理对严重脓毒症患者HMGB1变化的影响.严重脓毒症患者随机分为血糖控制A（4.4mmol/L~6.1mmol/L）、B（6.2mmol/L~8.3mmol/L）、C（8.4mmol/L~10.0mmol/L）三组.给予早期目标血糖管理,入ICU后0d、1d、3d、5d、7d采血测TNF-α、HMGB1浓度.三组TNF-α、HMGB1浓度及APACHEⅡ评分均呈下降趋势,A组HMGB1浓度及APACHEⅡ评分在第7d较B、C组明显降低（P＜0.05）.A组28d病死率较B、C组降低（P＆gt;0.05）.严重脓毒症患者在早期目标血糖管理下,显著降低HMGB1浓度,降低病死率和改善预后,HMGB1可用来评价脓毒症的严重程度及预后.     

THE FORUM

Internet plagiarism continues unabated and may even be increasing. Questions pertaining to the ethical-moral construct employed by students to justify Internet plagiarism among high school students have remained relatively untouched. Understanding not simply the prevalence of Internet plagiarism but also the variety of explanations used by students to justify their plagiarism seems crucial to curtailing its practice. In this study, I surveyed 160 high school students and endeavored to understand and describe the practices of students who use the Internet for schoolwork and who engage in copy-paste plagiarism or paper-buying practices. The results indicate that students are more easily able to justify copy-paste plagiarism for a variety of reasons that mirror justifications of other forms of conventional plagiarism. Most students indicated they would never purchase a paper for reasons ranging from fear of getting caught to more principled and nuanced ethical claims. Based on these results I also offer educators suggestions for refining assignments and evaluation methods.
