在当前教育改革中,专业学习共同体作为促进教师专业发展和提升教育质量的重要载体,扮演着至关重要的角色。教研组作为我国本土化实践中的专业学习共同体,在运行和发展中面临着价值导向功利化、教研活动形式化、教研内容浅表化、教研组织行政化等问题,严重制约了其效能的发挥。本文以耗散结构理论为基础,将专业学习共同体视作远离平衡态的开放复杂系统,以重构本土化专业学习共同体的实践,涵盖系统开放性、远离平衡态、非线性相互作用和有效涨落等关键特征,并提出重构本土化专业学习共同体的实践路径。建议通过搭建互通互联的协同网络,促进系统与外部环境的物质、能量和信息交换;以构建共创共享的创新体系,打破固有模式,激活创新动力;以优化随评随思的反思方式,建立动态反馈机制;以创生即识即传的放大模式,识别有效波动以促进系统变革等策略出发,全方位探索构建契合新时代教育发展需求的教师协作学习实践模式。

该文以塑料排水板联合水泥搅拌桩多元复合地基为研究对象,通过假定排水板的渗透系数随时间呈指数型衰减,考虑了排水板在固结过程中的淤堵效应对地基固结性状的影响。同时,该文还考虑排水板的涂抹效应、水泥搅拌桩的扰动效应以及土体的径-竖向耦合渗流,推导得出多元复合地基的固结控制方程及其解答。通过与已有解答和现场试验的对比分析,验证该文解答的正确性。最后,采用参数敏感性分析法对多元复合地基固结性状进行研究。研究结果表明:复合地基井阻因子θ对固结后期影响较大,当θ值较大时,径向渗流由于排水板的淤堵效应将提前终止,最终仅由竖向渗流使得地基达到完全固结;初始渗透系数k_0越大,井阻因子θ越小,涂抹作用越弱,板和桩的置换率越高,复合地基固结速率就越快。

本文基于中国家庭动态跟踪调查(CFPS)构建2014—2018年三期面板数据,应用固定效应和IV-2SLS模型研究了农机服务和农机自营对农户家庭劳动力配置和收入结构的影响,并分析了两种技术采纳方式背后的家庭特征差异,归纳出农机服务促进小农户生计多元化、农机自营促进生产专业化的主要特征。研究发现:(1)农户采纳农机服务会促使家庭劳动人口中纯农业劳动力转向兼业,该影响主要体现在非平原地区、全程机械化程度高的粮食品种产区以及农业生产自给程度较高的农户中,且受到土地规模的负向调节作用;而自购农机对家庭劳动力结构无显著影响。(2)农机服务通过促进劳动力结构调整提高家庭工资性收入,劳动配置起到完全中介作用;农机自营则主要通过农业专业化和规模化提高家庭农业经营收入。(3)倾向采纳农机服务的家庭土地规模较小、农产品消费不过度依赖自产,户主更多为女性,由于年龄和身体健康原因不适宜高强度农业劳动或专职经营农业,且户主教育程度较高、更规避风险。

党的二十大报告指出,要坚持人才引领驱动,加快建设人才强国;积极推进新型工业化,加快建设制造强国。本文以2016—2019年多地出台的人才引进政策为准自然实验,研究人才引进政策是否能够提高制造业企业的智能化水平。研究结果发现,人才引进政策的推出促使企业增加了工业机器人投资,促进了制造业智能化。机制检验表明,人才引进政策大幅度增加了高技能劳动力供给,并且未抬高企业劳动雇佣成本,企业因而招聘了更多高技能劳动力,特别是与机器人相关的技术员工,为工业机器人应用提供了人才支撑。进一步地,政策层面的异质性分析发现,当人才引进政策措施更多元化、更具针对性时,这种促进效应更强。企业层面的异质性分析发现,对于投资机会越多、研发密度越高的企业以及民营企业,这种促进效应更强。城市层面的异质性分析发现,在经济发展水平较高、政府干预较少以及房价较高的城市,这种促进效应更大。经济后果检验发现,人才引进政策带来的智能化扩大了企业市场占有率,改善了企业经营绩效。本文为实施人才强国战略、实现经济高质量发展提供了理论依据和政策参考。

数字版权贸易是数字贸易的重要组成部分,也是数字内容产业国际传播的重要形态。数字版权贸易具有全新特征,突出表现为数字版权贸易主体的多样性与微粒化,版权贸易客体的边界进一步泛化。其中,用户从传统版权贸易中的边缘角色转化为数字版权贸易中的重要参与主体。与此同时,用户介入型数字版权贸易使得版权贸易出现可版权性产品增加、交易过程低价高频化、信息搜寻匹配成本降低等新问题。文章指出,数字版权贸易的高质量发展需要关注并平衡用户介入型数字版权贸易中的版权保护程度、数据跨境流动规则及国内国际两种资源两种市场的关系。
