Artificial intelligence has become a driving force for national development and competition in the new era. Given this premise，greater emphasis must be placed on the popularization of artificial intelligence（AI）. Currently，societal perceptions of AI are constrained by traditional views，such as seeing AI merely as a tool or a daily object，which leads to a lack of comprehensive understanding of it. This Research explores the relationship between AI，the environment，and humanity，using concepts such as transparency，relevance，and augmentation. It proposes that AI popularization should be stratified and that traditional notions of popularization need to be altered. Stratified popularization means understanding AI from three levels：transparency pertains to the dissemination of AI mechanisms and principles，which is particularly meaningful for scientists；relevance concerns the relationship between AI and society，which holds significant social value and is closely related to the general public；and augmentation emphasizes the co-existence of humans and AI，which is crucial for humanity’s future in dealing with super intelligence. Changing traditional popularization notions involves a cognitive shift regarding AI from a tool to an intelligent entity and from an object to environment. Only in this way can AI be better directed towards public welfare and promote the healthy development of a new generation of AI in China.

Agricultural science popularization represents a crucial aspect of the socialized services provided by Science and Technology Backyards，playing a pivotal role in the transformation of agricultural scientific knowledge and technology into the agricultural production sector. This model is embedded within the overall structure of Science and Technology Backyards. Currently，agricultural science popularization faces challenges due to factors such as the segmentation of rural“acquaintance societies”，the complexity and diversity of agricultural issues，the uneven distribution of science popularization personnel，and the slow digital transformation. These factors lead to difficulties in establishing trust，insufficient personalized supply，unequal opportunities for science popularization，and relatively singular dissemination channels. By integrating Science and Technology Backyards into rural production and life，focusing on farmers’individual needs，consolidating talent resources，and enriching the forms of science popularization，they effectively address the general issues in agricultural science popularization and bridge the last mile in the transformation of agricultural science and technology into agricultural production. To enhance the efficiency of the agricultural science popularization model of the Backyard Science and Technology，it is recommended to accelerate the construction and improvement of the quality and quantity of Science and Technology Backyards，to promote the diversification of science popularization categories，to establish mechanisms for diverse participation，and to optimize the layout of agricultural network science popularization. These measures will better enable Science and Technology Backyards to fulfill their role in promoting agricultural technology.

In the existing discussions on the ethical governance of generative artificial intelligence（AI），user-level ethics have long been overlooked. Interactivity and generativity，as key attributes of generative AI，open an effective path for users to present themselves. The fusion of users and developers in the era of generative AI has long surpassed the integration of producers and consumers in economic activities，leading to the reconstruction of human social forms and the reshaping of humanity’s future. Therefore，the emergence and prioritization of user ethics should be seen as the future development direction of digital literacy. By combining individual and societal levels with the dimensions of positive and negative ethics，the constructed user ethics matrix provides a fundamental framework for the moral guidelines and norms that users should adhere to when facing and applying generative AI. To better implement this framework it requires the joint efforts of technology users，technology designers（developers），and technology regulators to promote a closer and more benevolent relationship between humans and technology，safeguarding human well-being and the future.

Generative artificial intelligence，by showcasing intelligence and creativity on par with human intelligence，transforms the understanding of intelligence and creativity away from a human-centric viewpoint. It surpasses general intelligence with its immense computing power and breaks through traditional creativity with seemingly nonsensical combinations. This shift has elevated artificial intelligence from a mere support tool for humans to a relatively autonomous creative force. In the evolving landscape of human-machine intelligence interactions and integration，individuals must embrace a continuous and dynamic dual spiral reconstruction of both technological literacy and humanistic creativity.

The primary goal of the“Elite Program”is to cultivate a cohort of students with a strong interest in scientific research and a commitment to engaging in foundational science and technology innovation. This program places high demands on the professional commitment levels of its participants. This study，based on a survey of 22 515 undergraduate students from 39“985 Project”universities，analyzes the impact of the“Elite Program”on students’professional commitment during their university years. The results show that male students，those from urban households，those whose fathers have a bachelor’s degree or higher，those studying at“C9 League”universities，and those in science，engineering，agriculture，or medical majors are more prevalent among“Elite Program”participants. Conversely，students from high schools in the western regions are less represented. The overall level of professional commitment，and the levels of idealistic and affective commitment，are significantly higher among“Elite Program”students compared to non-participants. The program has a significant positive impact on students’overall professional commitment，idealistic commitment，and affective commitment during university. Students from socioeconomically advantaged backgrounds and those in science，engineering，agriculture，or medical majors are more likely to have their professional commitment positively influenced by the“Elite Program”. Based on these findings，this research provides relevant recommendations.

Social media has become one of the primary channel for the public to obtain emergency science popularization information. In the social media context，emergency science popularization on mainstream media may reduce the cost of obtaining and identifying emergency science information for the public and promote the public to make sense of the risk and respond effectively. This study uses manual and computer-driven content analysis methods to examine the content of science popularization messages in People’s Daily microblog during the Covid-19 epidemic. The results show that emergency science popularization on People’s Daily microblog was situation-oriented to satisfy the public information needs and relied on authoritative sources to ensure the contents accuracy and reliability. It interpreted risks objectively and corrected misinformation continually to promote public understanding of the disease. In addition，sufficient efficacy information was transmitted to provide reliable guidance for the public. The study also indicates that knowledge about treatment and authoritative sources were significantly associated with greater public engagement. Accordingly，this study further illustrates the importance and mechanisms of situational factors and authoritative experts in mainstream media’s emergency science popularization，and explores the possibility of public participation in the collaborative network of emergency science popularization in social media context.

The construction of standard system for science and technology museum underlies the implementation of the standardization work，which is of great significance for the high-quality development of science and technology museum. However，existing literature rarely explored the standard system of science and technology museum systematically and comprehensively. After a full consideration of the current development status，future development trend，and standardization needs of science and technology museum by employing the standardization theories and methods，we proposed the principles of building the standard system，i.e.，comprehensiveness，practicality and moderate foresight，and built a three-dimensional model of standard system，i.e.，distribution field，standard level，and binding force of standard. The chart and diagram of standard system are mainly constructed from 7 distribution areas：basic general standard，facility construction，exhibition and education resource construction，service，operation management，information technology，and evaluation. Finally，based on the diagram of standard system，we put forward the countermeasures and suggestions for setting standards from two aspects，i.e.，the priority of the development of basic standards and urgent standards，and the consideration of the coordination of different levels of standards，for the purpose of providing reference for implementing the standardization work of science and technology museum systematically and programmatically.

The scientific community，an integral part of Sci-Fi films featuring disaster narratives，has been constructed as multiple images. As a key element in science communication，the images of the scientific community in films exert a tremendous impact on how accurately scientists，the public and mass media interpret its connotations. This study explores the image construction of the scientific community in Sci-Fi films from the perspective of comparative narratology. It starts with a survey of Western film history，focusing on the shifting roles of the scientific community，including a loosely-bound organization in name only，an old school hindering the advancement of science and technology，and an almighty savior. It then analyzes The Wandering Earth II，a great representative of contemporary Chinese Sci-Fi films，unveiling its imprints of Oriental culture as well as Chinese features. Based on this comparative study，it further points out that the images of the scientific community in films can boost the communication of scientific spirit and scientific ethics，strengthen the confidence of the human race as the determinant of historical progression，and provide valuable materials for the reflection upon and reconstruction of this community in the future.

Through the online questionnaire survey of 338 science and technology museums that have received free opening subsidy funds by the end of 2021 and the field investigation of some science and technology museums，we have a comprehensive grasp of the allocation，use，system construction，performance evaluation and supervision，and the effect of the policy about the national free open science and technology museums. The research results show that all regions highlight the importance of the free opening of science and technology museums，constantly strengthening institutional construction，and providing different levels of financial support. At the same time，they suggest that the supervising department should clarify the scope of expenditure of subsidy funds，take the exhibition and education area of science and technology museums and the annual audience number as the basic allocation factors of free opening subsidy funds，and appropriately consider the regional financial difficulties and performance evaluation results when allocating funds. Based on the above research results，this article puts forward some relevant suggestions for the clarification of the scope of free opening subsidy funds expenditure，the adoption of factor method for fund allocation，the encouragement of the construction of distinctive exhibits and exhibitions，and the strengthening of performance evaluation and supervision and management，which provides strong support for the drafting and promulgation of the“Management Measures for Free Open Science and Technology Museum Subsidy Funds”.

Using fine traditional Chinese culture in the naming of Chinese science and technology achievements is an active case of the science popularization，and it is necessary to analyze its characteristics and values. This study takes Micius Satellite for Quantum Science Experiments“Mozi”，amphibious aircraft“Kun Long”AG600，and the Chinese Lunar Exploration Program“Chang’e project’as the research objects，and analyzes the fine traditional Chinese culture in the naming of Chinese science and technology achievements from the perspective of constructivism. It is found that Chinese science and technologiy achievements are often named with such prestigious elements as the names of ancient Chinese scientists，and people，things or events in Chinese myths，poems and songs. The value of these practices in the field of science and technology culture includes the following aspects：The realization of the contemporary value of traditional culture，the promotion of the unity of sentiment，the inspiration of the public to participate in science popularization，and the interaction with other civilizations. Against this backdrop，this research argues that we should continue to promote the integration of fine traditional Chinese culture in the science popularization through innovative activities such as the naming of Chinese achievement of science and technology，and to increase the willingness of the public to access the content and participate in the science popularization activities.
