本文通过细读以弗所《面包师罢工政令》(Ephesos 231 = IK 12.215),考察罗马行省总督所采取的修辞与意识形态策略,并主张该政令体现了一种可称为“训诫式治理”的风格。相较于克利福德·安藤和迈尔斯·拉凡所辨析、学界较常讨论的普世式(ecumenical)与分化式(divisive)治理风格,训诫式治理以修辞克制、道德劝诫和有意暂缓惩罚为主要特征。本文以面包师这一不可或缺却经常遭受盘剥的劳动群体为中心,将该政令置于罗马行政沟通的广阔传统中考察,并与利巴尼乌斯所记述的四世纪安条克类似事件进行比较。此外,本文结合涉及基础设施与劳动规制的其他总督政令,说明这位元老院总督作出上述修辞选择的具体脉络,并探讨这种沟通方式如何反映帝国意识形态、地方社会期待以及罗马官员精英教养(paideia)所形成的多重压力。最终,训诫式治理呈现为一种务实且体察城邦社会需求的治理策略:它在维护地方共同体凝聚力的同时,也维持了罗马统治的权威。
Trace elements and isotopes (TEIs) are important to marine life and are essential tools for studying ocean processes1. Two different frameworks have arisen regarding marine TEI cycling: reversible scavenging favours water-column control on TEI distributions2–5, and seafloor boundary exchange emphasizes sedimentary imprints on water-column biogeochemistry6,7. These two views lead to disparate interpretations of TEI behaviours8–10. Here we use rare earth elements and neodymium isotopes as exemplar tracers of particle scavenging11 and boundary exchange6,7,12. We integrate these data with models of particle cycling and sediment diagenesis to propose a general framework for marine TEI cycling. We show that, for elements with greater affinity for manganese oxide than biogenic particles, scavenging is a net sink throughout the water column, contrary to a common assumption for reversible scavenging3,13. In this case, a benthic flux supports increasing elemental concentrations with water depth. This sedimentary source consists of two components: one recycled from elements scavenged by water-column particles, and another newly introduced to the water column through marine silicate weathering inside sediment8,14,15. Abyssal oxic diagenesis drives this benthic source, and exerts a strong influence on water-column biogeochemistry through seafloor geometry and bottom-intensified turbulent mixing16,17. Our findings affirm the role of authigenic minerals, often overshadowed by biogenic particles, in water-column cycling18, and suggest that the abyssal seafloor, often regarded as inactive, is a focus of biogeochemical transformation19,20.
