Analysis of single comments left for bioRxiv preprints till September 2019

IntroductionWhile early commenting on studies is seen as one of the advantages of preprints, the type of such comments, and the people who post them, have not been systematically explored.Materials and methodsWe analysed comments posted between 21 May 2015 and 9 September 2019 for 1983 bioRxiv preprints that received only one comment on the bioRxiv website. The comment types were classified by three coders independently, with all differences resolved by consensus.ResultsOur analysis showed that 69% of comments were posted by non-authors (N = 1366), and 31% by the preprints’ authors themselves (N = 617). Twelve percent of non-author comments (N = 168) were full review reports traditionally found during journal review, while the rest most commonly contained praises (N = 577, 42%), suggestions (N = 399, 29%), or criticisms (N = 226, 17%). Authors’ comments most commonly contained publication status updates (N = 354, 57%), additional study information (N = 158, 26%), or solicited feedback for the preprints (N = 65, 11%).ConclusionsOur results indicate that comments posted for bioRxiv preprints may have potential benefits for both the public and the scholarly community. Further research is needed to measure the direct impact of these comments on comments made by journal peer reviewers, subsequent preprint versions or journal publications.     

论死刑复核程序的完善路径

死刑复核程序是我国刑事诉讼中的一道特有程序。自死刑核准权统一收归最高人民法院之后,死刑复核程序的应有功能仍未完全发挥。近期发生的一系列死刑案件更使得死刑复核程序的完善再次成为人们极为关注的话题,死刑复核程序的修改也必将成为刑事诉讼法修改的规划内容之一。

The effects of school-based physical activity interventions on students' health-related fitness knowledge: A systematic review

This systematic review includes 34 studies examining the effects of school-based physical activity interventions on students' health-related fitness knowledge. The study design, methodological quality, and effectiveness of interventions on students' health-related fitness knowledge were analysed. The majority of the studies (79.4%) revealed significant positive intervention effects on students' health-related fitness knowledge. Studies examining adolescents were more frequently in a position to influence students' health-related fitness knowledge (87.5%) than studies examining children (75%), and studies with low methodological quality (88.8%) had more frequent positive effects than studies with moderate quality (75%). The effects on students' health-related fitness knowledge were independent of moderator variables such as the intervention content, duration and frequency. Only few studies were able to simultaneously positively influence students' health-related fitness knowledge and students' physical activity and/or fitness levels. These programmes can positively influence students' health-related fitness knowledge, but it remains unclear what the practical significance of these changes is. Further research is needed to clarify the influence of students' health-related fitness knowledge on reflection, understanding, physical activity behaviour, and overall physical literacy levels.     

Aiming for autonomy: formative peer assessment in a final-year undergraduate course

This article takes a dual focus on the theme of student formative peer assessment. On the one hand it offers a thorough literature review in this field, while on the other it unpacks a case study of curriculum design where peer assessment has been adopted. The practical example draws on recent changes made to a third- and final-year undergraduate research dissertation course in a UK architectural school. Although peer assessment worked quite well in this small setting, similar findings might be uncovered when scaled up to larger cohorts, as well as other disciplines and year groups. The research findings are certainly relevant for other contexts. Qualitative research from a focus group with six students on the course informs the empirical body of the paper. Through engaging with students’ reflections, as well as the relevant literature, and reflexively looking at the curriculum changes, this paper discusses some of the benefits and drawbacks that can arise from peer assessment in this context. Peer assessment is not without its challenges and hiccups, but, despite these, the benefit to autonomous critical thinking cannot be understated. And arguably peer assessment is especially germane for final-year undergraduates as they embark on employment or more advanced studies.     

Peer victimization,deviant peer affiliation and impulsivity: Predicting adolescent problem behaviors

Abundant evidence has demonstrated an association between peer victimization and adolescent problem behaviors. However, there is a large gap in knowledge about the potential mediators that associate peer victimization with problem behaviors and the potential moderators that exacerbate or buffer this association. The current study examined whether deviant peer affiliation mediated the association between peer victimization and problem behaviors and whether the direct and indirect associations were moderated by impulsivity. A sample of 1401 adolescents (50.1% boys, 11–14 years old) completed anonymous questionnaires regarding peer victimization, impulsivity, deviant peer affiliation, and problem behaviors. Gender, age and socioeconomic status (SES) were controlled for in the analyses. Structural equation models showed that peer victimization was significantly associated with more problem behaviors, and this association was mediated by deviant peer affiliation. Impulsivity moderated both the direct association (peer victimization → problem behaviors) and the second stage of the indirect path (deviant peer affiliation → problem behaviors). Specifically, these associations were especially stronger for adolescents with higher impulsivity. Identifying the processes by which peer victimization is associated with adolescent problem behaviors has important implications for an integrative framework of theory and prevention.     

对“训练周期”理论的重新审视

马特维耶夫的“训练周期”理论应属于训练的指导思想，而不是具体的训练方案。竞技状态和训练安排出现的周期性，是科学的规律，训练中必须遵循。但“训练周期”理论不能作为具体的训练安排，由于运动训练受许多因素的制约，其任何一种因素发生变化，必然导致整个训练过程实施周期发生改变。因此，必须依据训练的实际变化适时对训练周期进行适当的调节，同时，周期的划分和具体的训练方法应该依项目特点等情况来安排。
