Appropriate physical exercise has a positive impact on adolescents’physical and mental health,but there is a serious lack of physical exercise among Chinese *** to shape their exercise behavior(EB)has become an important task in promoting their development.A questionnaire survey was conducted using stratiﬁed cluster random sampling on three middle schools by class in Zhejiang Province,China to investigate the impact of exercise atmosphere(EA)on adolescents’exercise behavior and the mediating role of exercise identity(EI)and exercise habit(EH).806 adolescents were investigated by the Exercise Atmosphere Scale(EAS),Exercise-Identity Scale(EIS),Self-Report Habit Index(SRHI),and Physical Activity Rating Scale(PARS-3).The results show that:There is a signiﬁcant positive correlation between each two of exercise atmosphere,exercise identity,exercise habit,and exercise behavior(p<0.05).Exercise atmosphere could not only directly affect adolescents’physical exercise behavior but can also indirectly affect their physical exercise behavior through the mediating effect of exercise identity and exercise habit,involving three mediating pathways,namely,the mediating path through exercise identity,the mediating pathway through exercise habit and the chain mediating pathway through exercise identity and exercise *** direct effect of exercise atmosphere on exercise behavior was 0.459(p<0.01),accounting for 62.62% of the total effect of 0.733,and its indirect effect was 0.274,accounting for 37.28% of the total *** a certain extent,the mediating effect model reveals the mechanism of exercise atmosphere affecting exercise behavior and has a certain reference value for promoting adolescents’exercise *** should start by creating an exercise atmosphere,cultivating exercise identity,and enhancing exercise habits to help teenagers form active physical exercise behaviors.

高度复杂的全球化与逆全球化浪潮相互交织,形成了我们必须面对和应对的实际性;这种实际性以敞开的方式把价值提供给人类,也以隐蔽的形式把风险和代价抛给我们。从工业主义时代到当今智能化时代,新兴技术给予现代风险以变革性的传播力度和范围,自然风险让位于人为风险,单个本土性的风险极易演变成全球范围内不可控的叠加风险。随着当今算法技术越来越深入地渗透到个体日常生活和社会治理领域,出现了一种新型的算法风险和垄断性的算法权力,它危及个体的自主能动性、身份认同乃至集体行动的实践能力。由贝克和吉登斯发展起来的“风险”和“风险社会”概念并不是纯粹价值中立的描述性词项,而是隐含了一个规范性预设:支配风险分布和分配的权力结构对个体和集体的自主能动性带来不应得的伤害。一方面,我们可以借鉴贝克—吉登斯的风险社会框架去理解算法风险的性质;另一方面,我们也需要突破这一框架,在自主能动性的规范性层面为理解和范导算法风险和算法权力提供一个可证成的伦理批判。

在国际贸易补贴规制面临变革的情况下,各国在小多边和单边层面提出了改革方案。国际贸易中的补贴行为与补贴规则随着时代变迁有所发展,维护市场秩序、阻止降低社会总福利的补贴行为是补贴规则的根本目的,但随着新型补贴而来的反补贴新规在维持市场经济方面效果存疑。以欧美日方案、《外国补贴条例》和美国“汇率补贴新规”为代表的欧美日新型反补贴规则对传统规则进行了逻辑转向和规则升级,具体体现在拓展规制范围、引入竞争法规则和细化补贴专向性认定等方面。欧美国家的言行不一,折射其以反补贴规则限制他国发展相关产业、融入国际贸易体系的实质目的,中国需要经由国际法与国内法层面的不同路径消除欧美反补贴新规的不利影响。

《对外关系法》第三十八条规定了我国对外国组织进行管理的权力和外国实体遵守法律、不得危害中国国家安全的义务。外国代理人管理制度是这一规定的实现规则,有待落地实施。美国《外国代理人登记法》要求代理人就代理的相关信息进行登记,对代理关系中的关键内容做出界定,并就信息披露的内容和持续性提出要求。相关制度的执行总体具有较明确的法律指引,并设置了相应的违法惩处机制,该制度的执行在近年更趋主动化、严格化。该制度曾因对日本实体游说的执法效果不佳而有所加强,目前对于涉华实体的监管也日趋强硬,相关案例具有借鉴意义。我国可参考域外立法经验建立外国代理人管理制度。

伊拉克Missan油田复合盐膏层段含高压盐水层,其中BU区块某井12-1/4"井段钻遇含有超高压流体圈闭,使得本井段作业无安全钻井液密度窗口,作业中气侵、盐水溢流、井漏、缩径等井下复杂频出。后续钻进期间采取严格的ECD控制技术,简化钻具组合并优化参数;非钻进期间分层浆柱稳定井眼,分段控制起下管柱速度等措施,避免了局部超高压流体地层导致的涌、漏、卡等井下复杂,保障了井眼作业安全,积累了油田内相同井况的作业经验,同时也为其他油田同类地层提供了作业思路。
