高校学生党支部践行创先争优活动的创新思考

当前高校学生基层党组织在党员教育管理中的措施缺位亟待填补,而＂创先争优＂活动与学生党员教育的契合互动,为进一步加强高校学生基层党组织建设提供了可然诠释。文章拟以此为基石,对高校学生党支部在党员发展、组织管理、教育培养、考核评价等工作机制方面提出了改进对策,以在推动＂创先争优＂活动有效有序开展的同时,提升高校学生基层党组织的素养与水平。     

优势眼与网球技术的关系

运用优势眼原理（即人们在用眼时,天生就较多的以使用某一只眼为主）,对４３名运动员进行了测试研究,结果表明：视敏度与视觉深度对优势眼没有直接影响;优势眼的测定重复性好,准确性高;优势眼与正手击球线路有关;优势眼理论对合理的网球发球站位角度有重要意义。     

Novel groundtruth transformations for the aesthetic assessment problem

Aesthetic assessment evaluates the quality of a given image using subjective annotations, commonly user ratings, as a knowledge base. Rating complexity is usually relaxed in state-of-the-art works by employing a binary high/low quality label computed from the mean value of rating votes. Nevertheless, this approach introduces uncertainty to average-quality images, which may affect the performance of machine learning models trained from annotated data.In this work, we present a novel approach to aesthetic assessment based on redefining the rating-based groundtruths present in most datasets. Our intent is twofold: to reduce the rating uncertainty and to automatically group them into clusters reflecting high and low quality patterns, thus avoiding an arbitrary threshold like 5 in 1–10 ratings. The experimentation uses the well-known AVA dataset, which consists of more than 255,000 images, and we train several CNN models to test our new groundtruths against the baseline ones. The results show that our approach achieves significant performance gains, between 3% and 9% more balanced accuracy than the baseline groundtruths.
