美国洛杉矶从上世纪六十年代开始治理严重的空气污染.洛杉矶独特的地理环境造成机动车尾气排放难以消散,采取的干预措施包括制定排放标准、搬迁污染企业、使用清洁燃料、控制交通工具以及改变出行行为等.经过治理,空气中氮氧化物排放量以及人体血铅含量逐年下降.一些创新举措如企业平均油耗标准、零排放汽车更新计划、温室气体排放限额与交易计划、燃油税改革以及按里程收费实验也取得了进展,对今天中国城市实现碳达峰、碳中和目标以及交通领域市场化改革具有一定的借鉴意义.

人工智能已成为人类社会第四次技术革命的先导,它在图书馆领域扮演越来越重要的角色.人工智能在国外图书馆中的应用愈加广泛,在国内图书馆中也逐步推广使用.据统计,女性馆员约占图书馆馆员工总人数的三分之二,人工智能背景下的图书馆会促使她们把自身情感细腻、丰富且善于社交等优势充分发挥和展现,但也会产生部分女性馆员工作岗位被替代的风险,加剧女性馆员转岗和再学习的压力.为了减少人工智能对女性馆员的不利影响,她们需要按照人工智能时代图书馆馆员素质要求构建新的知识体系,不断提高自我学习能力,优化知识结构和加快业务能力更新.
