作为影响幼儿及其家庭的重要外部环境,社区支持可以有效解决家庭育儿功能弱化的问题。为充分发挥社区对幼儿家庭教育的支持作用,需构建系统科学的指标体系,以明确社区支持的内容、现状与发展方向。以六领域三层次体系为理论框架,基于国际大型项目的经验,初步构建幼儿家庭教育的社区支持指标体系,并运用德尔菲法对各项指标进行三次修订,形成包含6个一级指标、13.二级指标、26个三级指标的幼儿家庭教育的社区支持指标体系。基于修订后的指标体系编制调查问卷,以1 23.位幼儿家长为被试调查幼儿家庭教育社区支持的现状,结果发现:社区总体支持状况差,各领域支持不均衡,表现为在物质环境方面支持最为充足,在文化娱乐方面支持最为匮乏。为完善幼儿家庭教育的社区支持,政府需要完善社区支持制度与经费保障机制;社区需要加强重视,丰富支持内容与形式;管理部门需要对社区支持状况加强评估与监测。

为探析世界强队在比赛当中表现出的核心特征及中国男篮与世界强队之间在技战术等方面的差距,通过文献资料、专家访谈、录像观察及数理统计等方法,对2019年国际篮联篮球世界杯当中的8强球队比赛表现及世界篮球近些年来的发展和变化进行深度分析。研究表明,随着世界各国职业篮球赛事的广泛开展,各国篮球人才频繁流动,极大地促进了篮球技战术打法的融合与发展。世界强队在战术体系的构建上,更加以外线进攻为主,三分球已成为球队重要进攻手段;在具体进攻方式上,内线球员在低位进攻的占比明显减少,外线策应能力提升;在对比赛节奏的把握上,能够均衡掌握节奏与进攻效率的关系;在进攻与防守的关系上,8强球队攻防效率更加平衡,表现出了攻守兼备的特征;同时在一支球队的构建上,主教练与核心球员能够保持长时间的稳定状态。反观中国男篮在技战术方面有着明显偏离世界篮球技战术发展趋势的倾向。

为了探究矿山高湿环境下围岩体的力学特性,基于自制的湿度环境控制模拟装置,研究单轴压缩条件下不同相对湿度条件(70%,80%,90%和100%)下的砂岩试样的力学特征及劣化机理。研究结果表明:1)随着环境相对湿度的增加,砂岩的孔隙度逐渐增加,而质量和强度均明显降低,但湿度对试件的腐蚀能力在达到一定时间后变弱;2)在单轴压缩条件下砂岩的声发射变化规律与应力演化特征较为一致,高湿环境下试样声发射事件数量比干燥条件下明显减少;3.随着环境相对湿度的增大,砂岩破碎的分形维数逐渐增大,分形位置参数和碎块尺度参数值逐渐变小,砂岩破坏后碎块尺寸和分布集中程度逐渐变小。4)砂岩钠长石和方解石峰值衍射强度及矿物含量均随相对湿度的增大而降低,而微裂纹大小及数量则随相对湿度的增大而增大,高湿环境下砂岩的损伤劣化机理包含了物理和化学侵蚀等联合作用结果。研究结果将为矿山高湿环境下围岩稳定性控制提供一定的参考。

目的对2~6岁儿童进行语音评估,探讨语音的发展现状及其影响因素。方法纳入2021年7月—2022年2月于山东省千佛山医院门诊正常体检的2~6岁儿童198名,每隔0.5岁共8个年龄组,采用《2~6岁儿童语言发育评估量表》对入组儿童进行语音评估,并分析影响因素。结果1)声母m、b、t、j为1级;声母x、p、n、h、q、g、d为2级;声k、f、l、ch、sh、zh、c、z、r为3.;声母s为4级。1~3.均达标,4级不达标。韵母均达标。按年龄段来看,声母在2~4岁部分不达标,在4~6岁均达标;韵母在2.5~5.5岁达标。2)挑食、进食固体食物年龄晚、使用方言交流及屏幕时间长与声母错误率高相关(P<0.05);挑食、半流质饮食、主要代养人学历为小学、使用方言交流及工作日屏幕时间长与韵母错误率高相关(P<0.05)。结论年龄与语音发展相关性最显著,语音在4岁时全部掌握。饮食行为、家庭语言环境、主要代养人、屏幕时间与相关儿童语音发育密切相关。
