妈妈与女儿的对话

女儿：中国地质大学大一学生 妈妈：中国无神论学会理事 女儿：妈妈,我的辅导员向我介绍了一本书《心灵的自救》（peace in mind）。据说它在美国畅销了50多年。现在国内也很热销。我觉得它特别符合我的想法,好像它解决了我好多关于人生、对社会的看法问题。所以我想让它成为手边书,能经常参照着做。     

从“扁鹊自责”谈我国糖尿病防治现状及对策

全球糖尿病发病率日益增多。我国糖尿病诊断率及治疗达标率低,并发症发生率高、进展快,治疗现状令人担忧。减轻体重干预糖耐量受损,是决定疾病转归的关键环节、生活方式及药物干预均可降低糖尿病发生率。只有重视普及糖尿病相关知识,提高专业队伍素质,针对高危人群重点筛查及干预,早期发现糖尿病及综合治疗,才有可能减少糖尿病发病率及致残、致死率。     

“科学与宗教”——一个值得关注的研究课题

视觉表象扫描中的视角大小效应

采用视觉表象的几何距离扫描任务,通过两个实验首次揭示了视觉表象扫描中的视角大小效应。实验一采用3 (视角：2.7°,5.5°和8.2°) × 3 (扫描距离：0.0cm、0.4cm和0.8cm) 组内实验设计,探讨了视角大小这种表象前加工因素是否影响心理扫描的问题;实验二采用8 (视角：2.7°,4.1°,5.5°,6.9°,8.2°,9.6°,12.3°和17.1°) × 2 (扫描距离：0.4cm和0.8cm) 组内实验设计,探讨了视角大小如何影响心理扫描加工过程的问题。结果表明：（1）在视觉表象扫描中,扫描时间会受到表象对应刺激的视角大小影响,即使扫描的几何距离相等,不同视角大小条件下的扫描时间仍存在显著差异;（2）在4°到10°这个视角范围内心理扫描的时间显著短于这个范围之外的扫描时间,6.5°左右是视觉表象扫描的最佳视角。视角大小效应有别于心理扫描的大小效应和距离效应,为Kosslyn的表象计算理论增加了新的内容,具有重要的理论意义。同时它对仪表、图形设计以及棋牌游戏等工作和生活实践具有一定的应用价值     

条件推理与概率判断

选取6个具体内容的条件命题和1个纯形式的条件命题作为实验材料,以大学生为被试,深入探讨了条件推理的认知加工机制。结果发现,大学生被试对四种推理形式的认可程度主要与范畴前提的概率值成正比,条件推理似乎是一种基于概率判断的直觉而高效的认知加工过程,进一步证实了Oaksford（2000）以及Evans（2003）等人的观点。     

Positive emotion modulates cognitive control: An event‐related potentials study

There is substantial evidence to indicate that negative emotion can modulate cognitive control processing. However, only a few studies have investigated this effect with positive emotion. Therefore, the present study explored the electrophysiological correlates of the impact of positive emotional stimuli on cognitive control, using event‐related potentials (ERPs). Sixteen healthy young adults completed a modified Simon task (Simon, 1969). Behavioral data indicated that reaction times were faster for positive emotional stimuli than for neutral emotional stimuli in the incongruent condition, but not in the congruent condition, which suggested that positive emotion expedited conflict resolution. The ERP data showed that two negative ERP components (N300–400 and N450–550) were associated with the positive emotional stimuli in the incongruent minus congruent condition. It is suggested that these components may respectively be related to the conflict monitoring (N300–400) and response selection (N450–550) stages of cognitive control processing. Overall, our results indicated that positive emotion could facilitate cognitive control processing. These results are in line with the neuropsychological theory, according to which, positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.     

In situ measurement of GaN film photoluminescence under plasma etching

This work focuses on an improved method that enables us to measure in situ GaN film photoluminescence (PL) under Ar or N₂ plasma etching. Although the background signal is large and increases with bias voltage, the GaN PL can be obtained after subtraction of this background from the total luminescence. Moreover, after plasma etching, the intensities of the near-band-edge and the yellow luminescence decrease significantly. It is suggested that this behaviour is strongly related to the heavy plasma-induced damage, which includes non-radiative defects and deep-level defects, such as Ga vacancies and/or C impurities.     

Family boundary characteristics,work–family conflict and life satisfaction: A moderated mediation model

Although work–family border and boundary theory suggest individuals' boundary characteristics influence their work–family relationship, it is largely unknown how boundary flexibility and permeability mutually influence work–family conflict and subsequent employee outcomes. Moreover, the existing work–family conflict research has been mainly conducted in the United States and other Western countries. To address these gaps in the work–family literature, the present study examines a moderated mediation model regarding how family boundary characteristics may influence individuals' work–family conflict and life satisfaction with a sample of 278 Chinese full‐time employees. Results showed that employees' family flexibility negatively related to their perceived work interference with family (WIF) and family interference with work (FIW), and both these two relationships were augmented by individuals' family permeability. In addition, WIF mediated the relationship between family flexibility and life satisfaction; the indirect effect of family flexibility on life satisfaction via WIF was stronger for individuals with higher family permeability. The theoretical and managerial implications of these findings are discussed.
