The Makran accretionary wedge has the smallest subduction angle among any accretionary prism in the world. The factors controlling the spacing and morphological development of its deep thrust faults, as well as the formation mechanism of shallow normal faults, remain unclear. Meanwhile, the factors affecting the continuity of plane faults must be comprehensively discussed. Clarifying the development characteristics and deformation mechanisms of the Makran accretionary wedge is crucial to effectively guide the exploration of gas hydrate deposits in the area. This study aims to interpret seismic data to identify typical structures in the Makran accretionary wedge, including deep imbricate thrust faults, shallow and small normal faults, wedge-shaped piggyback basins, mud diapirs with fuzzy and disorderly characteristics of reflection, décollements with a northward tilt of 1° – 2°, and large seamounts. Physical simulation-based experiments are performed to comprehensively analyze the results of the plane, section, and slices of the wedge. Results reveal that the distances between and shapes of thrust faults in the deep parts of the Makran accretionary wedge are controlled by the bottom décollement. The uplift of the thrust fault-related folds and the upwelling of the mud diapirs primarily contribute to the formation of small normal faults in the shallow part of the area. The mud diapirs originate from plastic material at the bottom, while those that have developed in the area near the trench are larger. Seamounts and mud diapirs break the continuity of fault plane distribution.

ChatGPT凭借大语言模型的超强算力对人之本质的语言性进行赶超,进而引发人类有史以来对技术与人主体性博弈的深切关注。教育场域因其显著的语言性标识,使如何面对以ChatGPT为代表的强人工智能成为紧迫问题。国际、国内高校及其相关教育机构针对ChatGPT的教育介入表现出二值逻辑对立的不兼容态势,随着认识的深入日趋理性与辩证。为了因应技术时代之需、教育发展之要,需要秉持马克思主义人学发展观,以教育的本质旨在人文精神养成的第一原则,综合教育哲学、语言哲学的逻辑,运用概念思辨法、返本开新法、质性研究法对以ChatGPT为代表人工智能的技术本性进行深度揭示。ChatGPT强大的语言算力终究来自人类的智能投喂,属于“事后诸葛亮”的归纳逻辑,语言学习能力的人类本源性获取为教育的人文返场提供技术自反性动力,人的本性在今天的信息技术时代越发表征出自身的强语言性。循此逻辑,需要警惕教育与技术辩证发展进程中出现技术官僚主义、技术工具理性、技术资本逻辑对教育人文返场的异化阻挠。

缩小机会不平等,消除收入差距扩大的源生动力,从而达到分配公平,是实现共同富裕的必由之路,也是推进中国式现代化的治理抓手。本文采用基于集成回归树算法的机器学习模型,同时引入分位数回归森林将收入均值的机会不平等拓展至收入分布的机会不平等。本文基于2010~2021年中国综合社会调查数据的测算结果表明,以基尼系数衡量的全样本收入均值的机会不平等约为0.244~0.307,大致占总体不平等的38.1%~52.4%,这种非线性机器学习模型的测算结果明显高于依赖线性模型的传统测算方法。城镇居民收入的机会不平等高于农村,环境因素对城乡间收入差距形成的贡献度最大;个体及其父亲的可观测特征差异更倾向于拉大收入差距,而其母亲的可观测特征则相反。另外,收入分布的机会不平等测算结果表明,环境因素显著影响子代的收入风险,优良的环境基础更倾向于赋予子代收入分布的右偏优势;从分布结构看,收入下限、收入上限、偶然收入和收入风险的不平等程度都显著高于收入均值的机会不平等。
