比利时微电子研究中心计划利用超导缩小计算机。科学家预测,到2040年,计算消耗的电力将占全球总量的50%。这一预测是在生成式人工智能爆发之前作出的。过去十多年来,训练大型人工智能模型所需的计算资源大约每6个月就会翻一番。按照这个速度,到2030年,训练一个人工智能模型所需的计算资源将是当前十大超级计算机年度所需资源之和的100倍。简而言之,计算需要的巨大电力能源,很快将超出地球所能提供的范围。

基于场域理论视角,运用参与式观察和半结构式访谈的质性研究方法,对S市冰球场域中多元主体的利益诉求与实践逻辑进行分析。研究认为:冰球场域中多元主体不同的利益诉求产生特定的实践逻辑。地方政府的利益诉求表现为政绩与平稳,凭借政治资本占据场域的主导权,生成支配惯习和行政干预逻辑;占据经济资本、文化资本和社会资本的冰球俱乐部、教练员和学员家长在场域中处于弱势地位,是场域规则的被动执行者,话语权有限。政策执行存在利益冲突、行动主体独立性缺失、地方政府行为异化成为制约S市冰球运动高质量发展的主要因素,其推动路径在于重建场域秩序、发挥协会作用、重塑政府惯习。
