公正世界信念对大学生学习成绩的影响:时间管理的解释

为探讨公正世界信念对大学生学习成绩的影响,并说明时间管理因素在二者关系中的作用机制,研究1以205名大学生为被试,采用问卷法探讨了公正世界信念通过时间管理对大学生实际学习成绩起作用的机制。结果表明,时间管理倾向在公正世界信念和学习成绩的关系中起部分中介作用。研究2随机选取120名大学生为被试,采用启动实验范式考察了公正世界信念对时间规划的影响。结果表明,当启动不公正信念时,个体计划学习投入时间显著减少,同时伴随娱乐等其他时间增加。总之,公正世界信念可部分通过影响大学生的时间管理进而影响其学习成绩,而且大学生对不公正信念更敏感。     

The relationship among resilience,rumination and posttraumatic growth in hemodialysis patients in North China

Research has indicated that clinical serious disease may lead to posttraumatic growth (PTG). However, little is known about PTG among hemodialysis (HD) patients. The study examined the relationship among resilience, rumination and PTG among Chinese HD patients. 196 HD patients were recruited from a tertiary hospital in a Northern city of China between 1 June 2015 and 30 May 2016. Patients were surveyed using the Posttraumatic Growth Inventory-Chinese version, Connor-Davidson Resilience Scale, and Chinese Event Related Rumination Inventory. Correlation analyses showed that resilience was most highly positively correlated with PTG (r = .70, p < .001), deliberate rumination moderately correlated to PTG (r = .50, p < .001), and intrusive rumination was lower negatively related to PTG (r = –.26, p < .001). Regression analyses showed that age, gender, duration of dialysis, resilience and deliberate rumination had significant associations with PTG (β = ?.31, p ＜ .0001; β = –.14, p = .002; β = .10, p = .032; β = .44, p < .001; β = .20, p < .001). They together explained 65% of the total variance in PTG (F [8,195] = 46.74, p < .001). However, intrusive rumination was not associated with PTG (p > .05). The results suggested that resilience and deliberate rumination may be instrumental for PTG improvement.     

Children show limited movement repertoire when learning a novel motor skill

Examining age differences in motor learning using real‐world tasks is often problematic due to task novelty and biomechanical confounds. Here, we investigated how children and adults acquire a novel motor skill in a virtual environment. Participants of three different age groups (9‐year‐olds, 12‐year‐olds, and adults) learned to use their upper body movements to control a cursor on a computer screen. Results showed that 9‐year‐old and 12‐year‐old children showed poorer ability to control the cursor at the end of practice. Critically, when we investigated the movement coordination, we found that the lower task performance of children was associated with limited exploration of their movement repertoire. These results reveal the critical role of motor exploration in understanding developmental differences in motor learning.     

Normative values for a tablet computer-based application to assess chromatic contrast sensitivity

Tablet computer displays are amenable for the development of vision tests in a portable form. Assessing color vision using an easily accessible and portable test may help in the self-monitoring of vision-related changes in ocular/systemic conditions and assist in the early detection of disease processes. Tablet computer-based games were developed with different levels of gamification as a more portable option to assess chromatic contrast sensitivity. Game 1 was designed as a clinical version with no gaming elements. Game 2 was a gamified version of game 1 (added fun elements: feedback, scores, and sounds) and game 3 was a complete game with vision task nested within. The current study aimed to determine the normative values and evaluate repeatability of the tablet computer-based games in comparison with an established test, the Cambridge Colour Test (CCT) Trivector test. Normally sighted individuals [N = 100, median (range) age 19.0 years (18–56 years)] had their chromatic contrast sensitivity evaluated binocularly using the three games and the CCT. Games 1 and 2 and the CCT showed similar absolute thresholds and tolerance intervals, and game 3 had significantly lower values than games 1, 2, and the CCT, due to visual task differences. With the exception of game 3 for blue-yellow, the CCT and tablet computer-based games showed similar repeatability with comparable 95% limits of agreement. The custom-designed games are portable, rapid, and may find application in routine clinical practice, especially for testing younger populations.     

Subject Matter Expert Judgments Regarding the Relative Importance of Competencies are not Useful for Choosing the Test Batteries that Best Predict Performance

Several recent articles have suggested that assessments of the relative importance of different abilities or competencies to a job have little bearing on the criterion‐related validity of these selection tests that measure those abilities. We hypothesize that selection test batteries chosen to maximize the judged importance of knowledge, skills, and abilities will not predict performance better than batteries of tests chosen at random. The results in two independent samples consistently show that the validity of test batteries chosen based on subject matter expert judgments of importance is not different from the validity of batteries of a comparable number of tests chosen at random from a set of intercorrelated tests, or even those chosen to provide the worst possible match between test content and job content.

“临床路径”服务模式对于推进合理用药的伦理价值

药品是治病救人的物质基础,但要真正达到健康的目的,合理用药才是关键。从医学伦理学的视角来看采取临床路径服务模式推进临床合理用药,体现着“人本主义”的伦理原则,有利于患者“知情同意”原则的实现,有利于降低不合理的医药费用,有利于监测治疗效果,减少药物不良反应。     

1993至2009年大学生焦虑的变迁:一项横断历史研究

有研究表明,中学生的焦虑水平在逐年上升,那么大学生的焦虑水平是如何随年代变化的呢?大学生的焦虑水平是否存在性别差异呢?为此,我们选取1993至2009年间以Spielberger编制的状态-特质焦虑量表测量大学生状态焦虑的63篇和特质焦虑的66篇研究报告进行横断历史的元分析,以考察大学生状态和特质焦虑水平历年的变化情况和性别差异。结果表明:(1)1993至2009年大学生状态和特质焦虑均值与年代有显著正相关,这说明大学生的焦虑水平在逐年上升;(2)大学生状态焦虑增长速度要快于特质焦虑,而且年代对状态焦虑变异的解释率也高于特质焦虑;(3)在状态和特质焦虑上男女大学生得分都与年代有显著正相关,且在两种焦虑得分上均无显著的性别差异。

异种器官移植及其伦理问题

目前,开展的异种移植研究主要以猪为供体源,面临的主要障碍是宿主抗移植物的免疫排斥反应(超急性排斥、急性排斥和慢性排斥)和猪内源性反转录病毒感染,并已取得一定进展.但异种移植引发的伦理问题也不容忽视,主要有跨物种感染、卫生资源分配、动物的权利和人格同一性等问题.
