Tephra layers in the western Philippine Sea,characterized by abundant volcanic glass shards,may provide crucial evidence on the eruption history of volcanoes and tectonic evolution of the western Pacific.A 220-ka sediment core from the Benham Rise in the western Philippine Sea offers new insights into the provenance of four intercalated tephra layers(T1–T4,in chronological order)containing either colorless or brown glass *** to primitive mantle,all glass shards are enriched in large-ion lithophile elements,such as Rb,Cs,and Pb,and depleted in high field-strength elements,such as Th,Nb,and Ta,indicating a subduction-related *** colorless glass shards are characterized by high SiO_(2)(>78%)and light rare earth element(LREE)contents as well as high La/Sm ratios(>9),low FeO and MgO contents(100),pointing to a rhyolitic composition and a medium-K calc-alkaline serial *** contrast,the brown glass shards are characterized by lower SiO_(2)(3.)and LREE contents,higher FeO,MgO,and CaO contents,lower La/Sm(3.152 ka)and T4(172 ka)were correlated with volcanic deposits from the Taal and Laguna Caldera in the Maccolod Corridor,respectively,while the colorless glass shards from layers T1(3..5 ka)and T2(61.2 ka)were likely sourced from the Irosin Caldera in the Bicol *** the provenance of late Pleistocene tephra layers in the western Philippine Sea is helpful to complement a Philippine volcanic history and establish a regional tephrochronostratigraphy.

《公司法》是否应设置董事对第三人的民事责任,如何进行制度建构,是本次修订争论的焦点。囿于传统法人机关内部责任理论,我国立法长期缺乏董事对第三人责任的一般规则,事实上董事对第三人的民事责任是兼有行为法与组织法的法定责任。确立该责任,既要洞悉董事同时承载法人与个人双重人格的实质,又要看到董事控制公司与第三人形成信义义务关系的事实。我国在当前背景下增设董事对第三人民事责任的一般规则,虽然符合优化公司治理的现实需要,但也存在排斥该规则的不利因素,立法须考虑其生成机制和运作环境。对《公司法》新增董事对第三人民事责任条款的构成要件须经由类型化而准确把握,揭示对第三人双重责任保护结构之间的依附关系。该条嵌入公司法体系必须与其他相关规范相互兼容、和谐统一、避免法律冲突,才能充分发挥立法的预设功能。

各国对双控人规制的范式主要有直接规制与间接规制。美国的直接规制以判例法的形式确认双控人在特定场景对公司、股东或债权人负有信义义务,违者追究其赔偿责任;以英国和韩国为代表的间接规制范式,对双控人亲自执行公司业务的行为或指示董事执行公司业务的行为,要求其与董事共同对公司或第三人承担赔偿责任。我国公司属于股权高度集中型公司,决定了其治理模式必然是“双控人中心主义”,也决定了规制双控人的规范在公司法中至关重要。2005年修订的《中华人民共和国公司法》增设第二十一条对双控人施加了不得利用其关联关系损害公司利益的义务,开启了双控人直接规制的范式。2023.新修订通过的《中华人民共和国公司法》第一百九十二条规定了双控人指示公司事务与董事、高级管理人员承担连带责任,又引入了间接规制范式,从而形成了两种规制范式兼而有之的折中规制范式及规范体系。然而,该体系存在规范大多过于抽象、可操作性不强、所有规范皆为消极规范的弊端。后续双控人规范体系的改进和完善应细化禁止双控人滥用控制权的规范,提高可适用性和规制功效;增加双控人的积极规范,承认双控人在公司治理中的地位和控制公司的权力,规范和引导其依法行使权力,优化公司治理,从而奠定完善中国特色现代企业制度、弘扬企业家精神的制度基础。

教师交流是促进义务教育均衡发展的关键举措。本研究立足于辽宁省T县义务教育教师交流政策执行调研实况,利用政策网络理论分析框架,分析教师交流政策主体间的互动关系对政策执行成效的影响机制。研究发现,县域教师交流政策网络主体主要包括政策社群网络、府际网络、校际网络和议题网络,各网络主体之间的互动关系对县域教师交流政策执行成效具有显著影响作用。县域教师交流政策执行面临着政策社群网络内部的部门协同不畅、政策社群网络与府际网络间的利益取向冲突、校际网络内部的资源流动不畅、议题网络的参与程度不高等四大困境。基于此,破解县域教师交流政策执行中所面临的困境应畅通政策社群网络内部的跨部门合作通道,稳固跨部门合作关系;按照纵向职责同构原则,明确政策社群网络和府际网络的职责分工;调整校际网络内部的互动模式,疏通县乡学校交流渠道;畅通议题网络参与渠道,激发议题网络规模效应;调整校际网络内部的互动模式,疏通县乡学校交流渠道;畅通议题网络参与渠道,激发议题网络的规模效应。
