近年我国互联网平台就业呈现猛增趋势,明确平台用工模式下的劳动关系以保护平台劳动者权利之很有必要。从互联网平台用工模式的特性上看,劳动者与平台之间的从属性趋于弱化,且平台劳动者抵御社会风险的能力较差,致使该类劳动者的权利难以获得救济。然而我国现有法律规范没有很好地解决平台用工的劳动关系确认依据,造成法院在现有平台用工案件中对劳动关系认定的结果有一定出入。通过比较研究法分析中美两国在立法和司法裁判中认定平台用工模式下成立劳动关系的差异,借鉴美国的立法和司法实践经验,我国在立法上应当增设关于平台用工的兜底条款与负面清单条款,并根据平台与劳动者的法律地位差异改善举证责任的分配规范。同时在实践中应综合考虑实际工作的环境、单位对劳动者的实际控制,并衡量平台与劳动者在个案中所展现的实际利益,以明确平台用工模式下的劳动关系。

“元宇宙”作为由技术所营造的新型社会体系与数字生活空间,为推进中国特色“智能+”监督模式建设奠定了重要的技术基础。权力监督“元宇宙转向”以身体一技术耦合协同为基础、以真实一镜像主体交互为内容、以时空一思维边界突破为特征,实现了数字时代权力监督模式的创新。权力监督“元宇宙转向”以“共同在场”与深度沉浸体验、“心流状态”与具身社交网络、“虚拟化身”与认知心理调适为表现,在环境建构、互动方式、形态表征等方面呈现独特的运行机理。面对权力监督“元宇宙转向”存在的沉浸性与沉沦性对垒、主动性与臆想性角力、创新性与依赖性较量等风险,要从技术统摄、结构完善、价值引领等方面实现突破,加快推进新基建,形成监督新思路,探索伦理新观念,为权力监督“元宇宙转向”构筑发展基础、注重空间塑造、厘清核心表征。

为了研究纳秒脉冲激光与铝靶碎片的相互作用规律,建立了纳秒脉冲激光辐照铝靶碎片的动态响应仿真模型,采用COMSOL软件分析了不同作用时间和不同入射激光功率下的等离子体反喷羽流动力学特性,得到了不同激光参数变化对脉冲激光辐照铝靶碎片产生等离子体反喷羽流的演化规律。结果表明,相同脉冲激光功率作用下等离子体羽流反喷速度随作用时间的增加而增大;相同脉冲激光时间作用下,随着激光功率增加,等离子体反喷羽流的最大速度也不断增大;由于受等离子体屏蔽效应的影响,反喷羽流速度在25μs附近达到最大,在700 kW时最大速率为1.87×104 m/s,此时等离子体反喷羽流扩散半径增加了17 mm。该研究为纳秒脉冲激光辐照铝靶空间碎片降轨移除工程化应用提供了理论参考。

To investigate the effects of salinity on early development of Chinese mitten crab ( Eriocheir sinensis ), and the salinity tolerance mechanism of embryos, different developmental stages of embryos (gastrula, eyespot and pre-hatching stage), and hatched stage I zoea and megalopa, were exposed to a range of salinities (1, 5, 10, 15 (control), 20, 25, 30, 35 and 40). Hatching, survival and molting were monitored. Effects of 24-hour hypersaline (35) and hyposaline (1) stress on egg diameter, water content, Na +/K +-ATPase (NKA) activity, and crustacean hyperglycemic hormone (CHH) gene mRNA expression in embryos and megalopa, are reported. Embryos are more tolerant of low (≤ 5) than high (≥25) salinities, with optimum ranges for gastrula and pre-hatching stage embryos being 5-20, and for eyespot embryo and stage I zoea, 10-20. Most megalopa can molt to the first juvenile instar by day 5 at salinities between 1 and 40, whereas molting of megalopa stages was delayed at 40. Hypersaline conditions resulted in a loss of moisture, reduction of egg volume, and a signifi cant increase in NKA activity and CHH mRNA expression at some developmental stages. Hyposaline conditions did not affect moisture content or egg volume, but resulted in decreased NKA activity and CHH mRNA expression in embryos. For megalopa stages, NKA activity was significantly upregulated following both hypo- and hypersaline stress. Our results suggest high salinity will inhibit development and hatching of E. sinensis embryos, and low salinity will affect the survival of their stage I zoea. Increased NKA activity in embryos and megalopa stages might indicate a hyporegulation response under hypersaline conditions. These findings provide useful information for spawning ground protection of indigenous E . sinensis and enrich the knowledge of embryonic tolerance mechanisms of hyperregulating crustaceans following osmotic stress.

现在是构建当代中国话语体系的最佳时期,要正确理解构建当代中国话语体系“何以必要”“何以可行”“何以实现”等问题。正是有西方意识形态联合行动的制约力,有强势补足中国话语短板的内驱力,有提升党的长期执政能力的支撑力,使得构建当代中国话语体系“很必要”。正是中国强势崛起与西方中心神话式微形成鲜明对比,思想理论深化与社会主义实践探索形成良性互动,改革经验积累与国家建设显著成果形成交织融合,使得构建当代中国话语体系“能够行”。因此,要在话语贫困、表达滞后、资强社弱环境相交融中树立危机意识,在政治话语、学术话语、大众话语层次相统一中提升论证能力,在学理研究、传播实践、国际舆论斗争相结合中强化使命担当,从综合施策上来明确构建当代中国话语体系“这样办”。
