A call for mtDNA data quality control in forensic science

There is increasing evidence that many of the mitochondrial DNA (mtDNA) databases published in the fields of forensic science and molecular anthropology are flawed. An a posteriori phylogenetic analysis of the sequences could help to eliminate most of the errors and thus greatly improve data quality. However, previously published caveats and recommendations along these lines were not yet picked up by all researchers. Here we call for stringent quality control of mtDNA data by haplogroup-directed database comparisons. We take some problematic databases of East Asian mtDNAs, published in the Journal of Forensic Sciences and Forensic Science International, as examples to demonstrate the process of pinpointing obvious errors. Our results show that data sets are not only notoriously plagued by base shifts and artificial recombination but also by lab-specific phantom mutations, especially in the second hypervariable region (HVR-II).

武警工作倦怠及相关因素分析

Accumulating studies have been conducted on job burnout in the fields of organizational psychology and health psychology, but there are few studies investigating job burnout for people in the Chinese Armed Police Force(CAPF). This thesis explored the antecedents (social comparison, perceived control and perceived organizational support) and outcomes (incumbents’ level of task performance and psychological health) of job burnout, using data collected from 458 teachers (study 1) and 792 officers (470 lower level army cadres,150 commandos and 172 teachers, study 2) in CAPF. Two studies were carried out. The results are as follows: 1. There were significant differences among the three dimensions of job burnout for teachers: reduced accomplishment was rated significantly higher than cynicism and emotional exhaustion. 2. For the emotional exhaustion dimension, special technical soldiers gave the highest ratings and cadres provided the lowest ratings. Besides, special technical soldiers and teachers rated higher on cynicism than cadres did. 3. Perceived control significantly influenced job burnout: the higher the perceived control, the lower the three dimension of job burnout (emotional exhaustion, cynicism and reduced accomplishment). 4. Perceived control exerted impacts on psychological health directly and indirectly: the higher the perceived control, the better psychological health. Moreover, perceived control had significant effects on psychological health through emotional exhaustion: the higher the perceived control, the lower emotional exhaustion and the better psychological health. 5. The higher perceived organizational support, the lower the three dimensions of job burnout; perceived organizational support impacted psychological health through emotional exhaustion: the higher perceived organizational support, the lower emotional exhaustion and the better psychological health. 6. Job burnout exerted significant influence on task performance: the higher reduced accomplishment, the lower task performance rated by participants themselves. Drawing on the above results, measures would be taken in CAPF to enhance perceived control and perceived organizational support, to alleviate burnout and improve task performance and psychological health.

情绪对创造力影响的发展性特点

Although robust findings have been that positive mood leads to greater creativity, several other literatures have found that negative mood sometimes results in more creative performance than positive or neutral mood. Several possible explanations for this emotion–creativity link have been proposed by researchers, but there has not yet been definitive research identifying the mechanism(s) behind this relationship. This research represents an initial step in this direction, examining the possibility that Intelligence Current may be a contributing mechanism in the emotion–creativity link from the perspective of development. The object of the present study was to do the followings 1) the effects and mechanism(s) of emotions on creativity development from adolescence to young adulthood by Unusual Uses Test; 2) the possibility that Intelligence Current may be a contributing mechanism in the emotion–creativity link. The participants were 849 adolescents in high schools and 267 undergraduates in the university aged from 11 to 22 years old. The mechanism(s) for emotion-creativity link was explored by cognitive flexibility (assessed using Abstract Match Task), tolerance (inclusive) ratings (assessed using Categorization of Analogy Task), uses originality ratings, and confidence ratings. Results indicated that: 1) The level of creativity varied with age. It increased from 11 years on, but decreased at about 14 to improve again from 15 to 22 years. 2) The different effects of emotions on creativity development among adolescents and undergraduates emerged, but the effects of positive and negative emotions on creativity didn’t differ from each other for the whole participants. Furthermore, compared with positive and negative emotions, the neutral emotions produced the lowest creativity for 11.00-13.99 years old group, but produced the highest creativity for 14.00-14.99 and 17.00-21.99years old. 3) Positive emotions have been shown to enable individuals to higher level of cognitive flexibility and better performance than negative emotions by Abstract Match Task, which could be considered that the Intelligence Current may be a contributing mechanism in the emotion–creativity link. 4) Positive emotions have been shown to enable individuals to own higher confidence, to categorize items with more flexibility, to see more potential relatedness among unusual and atypical members of categories, to evaluate items more originality than negative emotions among most of participants, especially the group of 14.00-14.99 years old. In sum, the present study helps us to further understand that the term ‘Intelligence Current’ is further explained and the problems found in relationships between creativity and emotions. However, further research is required to explore and confirm the conclusions of the present study.
