We establish the global well-posedness for the multidimensional chemotaxis model with some classes of large initial data,especially the case when the rate of variation of ln v0(v0 is the chemical concentration)contains high oscillation and the initial density near the equilibrium is allowed to have large oscillation in ***,we show the optimal time-decay rates of the strong solutions under an additional perturbation assumption,which include specially the situations of d=2,3 and improve the previous time-decay *** method mainly relies on the introduce of the effective velocity and the application of the localization in Fourier spaces.

3′-Daidzein sulfonate sodium is a new synthetic water-soluble compound derived from daidzein（an active ingredient of the kudzu vine root）. It has been shown to have a protective effect on cerebral ischemia/reperfusion injury in rats. We plan to study the mechanism of its protective effect. 3′-Daidzein sulfonate sodium was injected in rats after cerebral ischemia/reperfusion injury. Results showed that 3′-daidzein sulfonate sodium significantly reduced mitochondrial swelling, significantly elevated the mitochondrial membrane potential, increased mitochondrial superoxide dismutase and glutathione peroxidase activities, and decreased mitochondrial malondialdehyde levels. 3′-Daidzein sulfonate sodium improved the structural integrity of the blood-brain barrier and reduced blood-brain barrier permeability. These findings confirmed that 3′-daidzein sulfonate sodium has a protective effect on mitochondrial functions after cerebral ischemia/reperfusion injury, improves brain energy metabolism, and provides protection against blood-brain barrier damage.

在商品经济中,资本既是一种生产要素,也是一种社会关系,它突破了经济领域的界限,僭越到社会领域,使社会围绕着资本逻辑展开,资本带来了社会的物化,将社会困入"物"的牢笼,社会关系被颠倒为物的关系。面对资本逻辑所构建的"物化"社会,社会治理偏离了社会整体利益的价值取向,步入"资本"设置的物化困局,产生了价值危机、组织危机、关系危机和合法性危机。20世纪以来,抵制资本的"社会反向运动"迫使国家重视社会治理的人本诉求。基于劳动力生产的相对独立性和资本增殖对人的依赖,人本逻辑内含着对资本的否定,回归人本逻辑是破解社会治理"资本"困局的根本途径。当前,西方社会治理的问题在于如何权衡"国家-社会"的关系;而我国"强政府-弱社会"的传统管理格局则促使我们的改革过程着重于对社会"松绑",充分发挥社会组织自主性。在人本逻辑下,构建我国创新社会治理的行动框架的重点在于:形成共识,建构多元治理主体的平等地位;实现共治,建构合作治理的路径;共享成果,合理统筹治理的主体与客体。

共同富裕是社会主义的本质要求,促进共同富裕最艰巨的任务在农村。乡村实现共同富裕的现实内涵体现在:激发农民积极性,提升农民致富能力,为农民提供公平的发展条件。研究证明,运行良好的乡村治理机制能有效提升资源配置效率,增强农村发展活力,形成公平有序的乡村发展环境。因此,实现乡村共同富裕亟需对乡村治理制度进行优化和创新。在激发乡村发展整体活力方面,应加强农村基层组织建设,发挥党建统领的引导功能;在提升农民致富能力方面,应规范乡村治理制度,充分落实乡村自治,厚植文化资本,发挥致富精英的带头作用;在保障公平方面,应积极拓展乡村治理资金来源渠道,采用先进的技术手段提升公共服务能力,促进基本公共服务均等化。

如何实现共同富裕是人类现代化发展中的重要内容,也是当今世界政治哲学发展的重大理论问题。把握共同富裕需要从人类文明思想史出发,既要肯定启蒙理性和现代文明的积极价值,又要正视其中存在的危机。通过反思、分析、梳理共同富裕与文明的关系,找寻推翻资本逻辑、进行实践改造和实现内在超越的方法。中国式现代化始终坚持马克思主义对现代性批判的基本立场,在中国共产党的领导下,中国对共同富裕的内涵和实现路径进行了系统性重塑,为世界人民实现共同富裕的伟大理想提供了新的现代化方案。

在经济全球化的趋势下,如何加快区域经济的发展一直是政府与学者研究的重点。文章运用Pfeffer和Salancik(1978)提出的资源相依理论(RDT)来剖析制造业与生产性服务业在不同时期的不同资源相依与控制关系,并指出在我国目前所处的工业化阶段,制造业与生产性服务业相互依赖的互动关系是目前区域经济发展的主要动力。文章以Hansen(1994)区域经济发展要素为基础,结合资源相依理论证明了双轮驱动是目前区域经济发展的最佳方式,并指出其对区域经济发展在五大方面产生的显著影响。
