Prevalence and correlates of meeting the muscle-strengthening exercise recommendations among Chinese children and adolescents: Results from 2019 Physical Activity and Fitness in China—The Youth Study

PurposeThis study aimed to describe the national prevalence of Chinese children and adolescents who met the World Health Organization muscle-strengthening exercise (MSE) recommendations and identify correlates of meeting the MSE recommendations.MethodsCross-sectional data from the 2019 Physical Activity and Fitness in China—The Youth Study, a nationally representative sample of Chinese children and adolescents (n = 80,413; mean age = 13.7 years; 53.9% girls) and their parents, were analyzed. Children and adolescents who reported engaging ≥3 days (up to 7 days) of MSE per week were classified as meeting the MSE recommendations. MSE, demographics, lifestyle behaviors (sport participation, moderate-to-vigorous physical activity, screen time, and sleep duration), exercise intention, peer and parental support, and parental MSE participation were assessed through self-reports. Logistic regression models were used to determine the correlates of meeting the MSE recommendations. The analyses were completed in 2020.ResultsOverall, 39.3% of children and adolescents met the MSE recommendations. Girls, 10th–12th graders, minorities, those from lower income households and those from families with lower parental education were less likely to meet the MSE recommendations. Children and adolescents who were proficient in ≥2 sports were more likely to meet the MSE recommendations (adjusted odds ratio (aOR) = 1.44, 95% confidence interval (95%CI): 1.26–1.65), as were those with more moderate-to-vigorous physical activity (aOR = 1.57, 95%CI: 1.53–1.61). Additionally, children and adolescents with high exercise intention (aOR = 1.60, 95%CI: 1.51–1.69), those whose parents met the adult MSE recommendations (aOR = 1.46, 95%CI: 1.40–1.52), and those who received high peer (aOR = 1.27, 95%CI: 1.20–1.34) and parental support (aOR = 1.07, 95%CI: 1.04–1.12) were more likely to meet the MSE recommendations.ConclusionLess than two-fifths of Chinese children and adolescents met the World Health Organization MSE recommendations. The correlates identified in our study can help inform the development of school and community based strategies and policies to enhance participation in MSE and improve muscular fitness of all Chinese children and adolescents.     

基于机器学习的Web链接的抽取

互联网网页是通过超链接连接起来的,为人们的日常生活和商务用途提供了非常丰富的信息资源。链接结构分析在万维网的很多研究领域发挥着越来越重要的作用。然而存在着许多与主题无关的链接,造成了主题漂移。本文分析了链接本身的特点,介绍了一种有监督机器学习方法自动地抽取网页中的相关链接。试验结果表明该算法具有实用的价值。     

基于径向基神经网络的专利申请数量预测研究

利用径向基神经网络,对国内外近年来专利申请数量进行了预测。预测结果同用时间序列ARMA模型预测的结果进行了比较。预测结果表明：良好训练的径向基神经网络的输出数据能与实际专利申请数较好地吻合,而且比ARMA预测方法更为有效,可作为专利预测的一种新手段。

基于要素细分的竞争情报四维分析框架

根据竞争情报的本质,提炼出竞争情报应包含的分析要素,并基于已有的方法提出了一个由分析对象、分析目标、情报过程、情报周期四维构成的分析框架,对框架构建的要求、框架的构成方式进行了研究。描述了框架表达的竞争情报理念、和框架能较容易明确应该分析的分析内容、可对现有竞争情报分析方法进行类分、可表达出竞争情报和战略的紧密联系、有利于形成企业的情报文化等特点。基于框架提出情报价值是在情报周期的循环中产生的。最后阐述了基于框架的竞争情报分析方法。
