《洁净煤技术》稿件退修未回的对策

通过统计《洁净煤技术》2010—2012年退修超过半年未回稿件的情况,说明作者无法修改、不满意刊用栏目、稿件处理周期过长、转投他刊或一稿多投、作者忘记修回或无法联系,是造成稿件超期未修回的主要原因。通过认真送审,缩短审稿周期;了解作者,做到因人而异;发挥专业优势,发掘文章新意;仔细检查修回稿,适当使用修改权等措施从主观上促进了编辑主动性的充分发挥。通过明确修稿时间,建立催修机制;借助技术手段,防止一稿多投;开展网络办公,优化编辑流程等措施从客观上完善了编辑部的稿件退修流程。通过以上措施,2013年《洁净煤技术》稿件修回率达到98%,提高了工作效率,实现了期刊质量的稳步提升。     

IPC分类修订中的技术演化研究

[目的/意义] 从专利分类修订角度研究技术演化,为技术演化研究提供新思路。[方法/过程] 首先根据IPC分类表H部2009-2018年的修订情况,总结出新增分类、删除分类、类内转移分类、类间转移分类4种修订类型。其次针对分类修订后产生的过档文献提出基于Word2vec+TextCNN模型的过档文献再分类方法,使新旧版分类表通过再分类专利产生衔接。最后结合H部2009年-2018年被修订分类及再分类专利进行技术演化初步探索。[结果/结论] 专利再分类模型可有效解决过档文献问题,为专利再分类工作提供参考,同时可衔接新旧版专利分类表;结合IPC分类修订及再分类专利可分析分类修订中的主要技术演化方向,为技术演化研究提供新视角。     

The myth of contextual interference learning benefit in sports practice: A systematic review and meta-analysis

The contextual interference (CI) model hypothesizes random practice (high CI) leads to inferior acquisition, but superior retention and transfer capabilities compared to blocked practice (low CI). These phenomena are well established in laboratory settings. However, the transfer to applied settings, particularly in sports practice is still under discussion. The aim of this systematic review and meta-analysis is to evaluate the possible generalisability of the CI phenomenon in sports-based contexts with regard to performance outcomes. Up to April 16th, 2022, five electronic databases (PubMed, Web of Science, Scopus, Taylor & Francis, and SciELO) were used to search for relevant studies investigating differences between blocked and random schedules at post-acquisition, retention, and/or transfer tests. Using the PICOS criteria, a total of 933 records were screened. Outcomes evaluating the acquisition, retention, and/or transfer performances in sports skills in healthy participants were included. The quality of the selected studies was scored using the PEDro scale. Thirty-seven studies were selected, of which twenty-seven were of good quality and the remaining ten were rated as fair quality. Out of 205 overall pooled outcomes, only 43 performance outcomes (21%) agreed with the CI phenomenon after the acquisition (18 out of 103), retention (19 out of 84), and/or transfer (6 out of 36) phases. No statistically significant overall difference between blocked and random practice was detected at post-acquisition (effect size (ES) = 0.1, p = 0.154), retention (ES = −0.159, p = 0.141) or transfer testing (ES = −0.243, p = 0.071). The subgroup analysis showed inferior acquisition and superior retention following random practice only in individuals aged 20–24 years (ES = 0.282, p = 0.030 during the acquisition, and ES = −0.405, p = 0.011 during retention), with no difference at transfer testing for this specific age group. No similar significant effects have been concurrently identified during both acquisition and retention phases in any of the remaining subgroups (e.g., examined based on experience level, sports, skills, and testing protocol categories). The present results suggest CI effects can only be confirmed under very limited conditions, which seriously challenges the extension of CI effects to the sport context in general. Problematic conclusions for children's learning are discussed, as well as future research strategies to better understand counterintuitive learning approaches.
