Short video is not only another media technology innovation in theinternet history,but also reconstructs the mimicry environment of mass media with a new code system,creating a new media landscape of"video surviv-al".This new prospect of social production and life in the political power structure,media industry economy,social culture and algorithm technology,respectively,reflect the appearance of the"unknown",the platform capital of the labor force,the cultural division of social classes and the confrontation of computing laws and regulations.At the same time,"video survival"also has its own occurrence and development logic and inter-nal order.With the rise of short video as a social representation,the dominant order of its future development will gradually change from a spontaneous order to a constructed order.
On the basis of grasping the universal laws of natural,social,and human thinking development,Marx and En-gels continuously deepened their understanding of the essence and special laws of capitalism,grasped the fun-damental trend of capitalism towards socialism,and established the great theory of Marxism.Marxist classical texts are important carriers of Marxist thought;But Marxist ideology will never be bound within the text.It is constantly awakened and participates in the real social movements in people's understanding and interpreta-tion.Marxism is not manifested as a static way of existence,but as a dynamic development process in the her-meneutical cycle of"practice-thought-text-thought-practice…".The interweaving and fusion of the scientific and revolutionary nature of Marxism is fully demonstrated in the living social practices and ideological move-ments of its creators and inheritors.
提升老年人获得感、幸福感是新时代老龄工作的根本目标.利用山东潍坊老年健康调查数据,在两阶段最小二乘法框架下评估了社区养老服务对老年人主观福祉的影响和作用机制.研究发现社区养老服务对老年人主观福祉有促进作用,且对主观福祉水平较高的老年人有更强效果.针对不同服务类型,接受医疗保健类服务对老年人主观福祉的促进作用最强;精神文化类与生活照料类服务共同利用对主观福祉的促进效果比仅利用两者其一更强.在作用机制方面,老年人接受社区养老服务可以通过改善睡眠质量、疼痛感与自评健康状况,提升其主观福祉.对此,应针对性优化社区养老服务供给、建设养老服务联合体,提高老年人福祉.
决定刑罚威慑力的两个关键变量是刑罚的严厉性和确定性,前者相当于后两者的乘积.当刑罚为监禁而非罚金时,罪犯对刑罚的确定性比对其严厉性的变化更加敏感.刑罚的及时性也会影响刑罚的威慑力,但在演化的意义上,它是刑罚确定性的另一种感知形式.随着刑罚的加重,刑罚威慑力的边际变化非常复杂,但罪刑相适应的原则主要是为了保持刑罚的边际威慑力,它可以激励潜在罪犯以轻罪取代重罪.描述犯罪和惩罚的函数图像应该是一条上升的曲线,尽管我们不能确定曲线斜率的复杂变化.
加快建设农业强国,首先要推进农业现代化.加快农业现代化,必须要紧紧围绕农业强国建设目标,走出一条与我国现实国情、农情相适应的中国特色农业现代化道路.目前,与农业强国目标的新任务、新要求相比,我国农业发展仍然整体实力不强、质量不高、效益不明显.在农业基础设施、农业产业发展、农业技术设备、农业经营服务主体、农业绿色发展等方面,还存在着一系列突出问题和明显短板,对我国农业现代化快速发展形成了一定制约.为进一步加快中国特色农业现代化,必须加快补齐农业现代化短板弱项,不断完善农业配套设施、促进三产深度融合、强化农业科技支撑、建强现代农业经营体系、推动农业绿色发展、健全农业支持保护体系.
