Esports players,got muscle? Competitive video game players’ physical activity,body fat,bone mineral content,and muscle mass in comparison to matched controls

BackgroundEsports players, like traditional athletes, practice for long hours and, thus, are vulnerable to the negative health effects of prolonged sitting. There is a lack of research on the physical activity and the health ramifications of prolonged sitting by competitive players. The purpose of this study was to investigate activity levels, body mass index (BMI), and body composition in collegiate esports players as compared to age-matched controls.MethodsTwenty-four male collegiate esports players and non-esports players between 18 and 25 years of age signed a written consent to participate. Physical activity was examined using daily activity (step count) with a wrist-worn activity tracker. A questionnaire assessing physical activity was also administered. Secondary outcomes included body-fat percentage, lean-body mass, BMI, and bone mineral content measured using dual X-ray absorptiometry.ResultsThe step count in the esports players was significantly lower than the age-matched controls (6040.2 ± 3028.6 vs. 12843.8 ± 5661.1; p = 0.004). Esports players exhibited greater body-fat percentage (p = 0.05), less lean body mass (p = 0.003), and less bone mineral content (p = 0.03), despite no difference in BMI between the esports and non-esports players.ConclusionAs compared to non-esports players, collegiate esports players were significantly less active and had a higher body-fat percentage, with lower lean body mass and bone mineral content. The BMIs showed no difference between the 2 groups. Esports athletes displayed significantly less activity and poor body composition, which are all correlated with potential health issues and risk of injury. BMI did not capture this difference and should not be considered as an accurate measure of health in competitive esports players.     

一种新的用于图像检索的颜色一空间特征

为了解决图像检索中颜色直方图无法描述颜色空间位置信息的问题,提出了一种新的基于色彩量化的凸壳内角直方图特征.针对量化后HSV颜色空间中某一具体量化颜色值对应像素点的空间分布,首先计算包含这些像素点位置信息的凸壳,并对该凸壳的所有内角建立直方图.然后处理所有量化颜色值提取整幅图像的凸壳内角直方图特征.将该方法和一些文献中提出的方法进行的比较实验结果表明:提出的新特征可以有效地描述颜色空间位置信息,在查准率和查全率指标上均优于已有文献中的一些方法.     

基于多进制小波变换的B超图像分类

纹理分析是肝脏B超图像识别的重要方法,本文利用多进制小波变换提取脂肪肝和正常肝脏的纹理特征,结合空域特性对B超肝脏图像进行分类,采用自适应浮动搜索算法进行特征筛选,经实验测试,取得了较好的效果。

形象建构的内涵、类型与话语实践

形象一直以来是哲学、社会心理学、文学等学科的经典话题,但相关研究往往采用宏观视角。受社会建构论思潮的影响,形象研究迎来了“话语转向”,形象建构与传播开始引发话语分析、语用学等领域学者的关注。尽管越来越多的研究者基于话语分析或会话分析探讨形象建构问题,但这些研究因缺乏合适的分析框架而总体显得片面、主观。为此,本研究在现有文献基础上,以形象的话语建构观为理论导向,尝试对形象建构的内涵、类型和话语实践方式作系统考察,以期能够为未来的形象研究提出一个可操作的分析框架。     

意象的传译

意象是文学理论的重要概念之一。在翻译的过程中,语言的转化只是表层,忠实地再现、传递源语中文化意象的异质性才是翻译的实质。在当前国际文化交流日益扩大和多元化的语境中,对源语中文化意象进行传译具有特殊的重要意义。
