Since the world entered the era of network information, the influence of the Internet has been expanding day by day, and today’s college students are deeply affected by the network environment, which has also brought unprecedented challenges to the moral education work of colleges and universities. The rule of law education for college students is a key point for the comprehensive implementation of the strategy of governing the country by law. How to enhance the effectiveness and recognition of the rule of law education for college students has become an important task of higher education. Therefore, strengthening the legal education of college students is not only an inevitable choice to fully implement the rule of law but also a realistic requirement to improve the level of higher education and realize the all-round development of college students. College students’ mental health education is an important part of the talent training system of colleges and universities, and in-depth exploration of the ideological and political laws of college students’ mental health education courses is an inevitable requirement for implementing the fundamental task of Lide Shuren. College students’ mental health education courses must be integrated into the ideological and political concepts of the curriculum, reflect the political orientation of ideological and political work, embody the law of educating people with morality as the first, and embody the practical purpose of psychology to pay attention to personality improvement. It is necessary to optimize the content of education and teaching, excavate the elements of ideological politics in the curriculum, enrich the resources of ideological politics in the curriculum, and explore a new way of reforming the ideological and political education curriculum for college students from the aspects of deeply planting family and national feelings, enhancing political identity, strengthening cultural self-confidence, cultivating Chinese temperament, clarifying the meaning of life, strengthening mission responsibility, enhancing civic awareness, and developing law-abiding habits. Strictly regulate the behavior of contemporary college students in the online environment, give full play to the role of legal education, and reduce the incidence of online incidents such as online fraud and cyber violence. This paper puts forward some problems in the current legal education of college students in China and points out the root causes of these problems. Methods for structural reform and advanced cultural construction based on social development are proposed. From a strategic point of view, it is believed that only by managing the reform of legal education and cultivating civic awareness can we completely solve various contradictions and problems among college students in the network environment and pave the way for the development of college students.

A person’s family of origin has a profound impact on his or her life; a student’s performance at university and their interpersonal skills are also influenced by the characteristics of their family. In order to explore how social capital and intergenerational mobility impact university students’ quality of interpersonal communication and experiences, whether there is a “Matthew effect” at the higher education level, how the external social capital and the parenting style within a family affect the comprehensive quality of university students separately, and how university students’ family characteristics impact their quality of interpersonal communication, which will in turn affect their performance at university, this paper starts from the perspective of social capital and intergenerational mobility, and uses the cross-sectional data of the China Family Tracking Survey (CFPS) from 2018 to conduct Kaiser-Meyer-Olkin analysis and logistic binary regression for 1037 university students nationwide, to check whether the selected variables can be subjected to principal component analysis. The results show that, on one hand, university students’ family characteristics have a significant positive impact on their quality of interpersonal communication; on the other hand, their family backgrounds also have significant impact on their academic performance and enthusiasm for participating in student unions, as well as part-time employment and internships. In addition, according to the results of the mediation test, interpersonal communication skills play a mediating role in the way that family characteristics impact students’ performance at university, including their participation in student organizations, as well as internships and part-time jobs. Finally, this paper, by referring to both theoretical and empirical analysis, presents relevant suggestions from the perspectives of the individual, family, and government, aiming to facilitate the sustainable development of university students.

With the acceleration of population aging in China, the care of middle-aged and older adults has become the focus of social attention. As China is an “acquaintance society,” strong social relations play an important role in residents’ access to information and resource allocation, which has an impact on the choice of long-term care models for middle-aged and older adults. Therefore, based on the 19,728 samples from the 2018 CHARLS Phase I data, an empirical analysis was conducted using a logistic dichotomous model, which showed that both kinship (p < 0.01) and friendship (p < 0.01) among social relationships positively influenced the choice of social care models for middle-aged and older adults. The analysis of the heterogeneity showed that the choice of long-term care models was significantly influenced by strong social relationships in the central and western regions and rural areas (p < 0.01). On the basis of this, the transmission mechanism of strong social relationships was further analyzed in conjunction with the further construction of the SIRS Contagion Model, which was used to describe the information transmission process. The results showed that residents who attached importance to strong social ties were more likely to incur medical transfer expenditure, thus further increasing their own demand for the formal care model. The policy implications of this study are to promote the coordinated development of long-term formal care and strong social relations, to further promote the socialization of the formal care model while relying on traditional family care, and to build a multi-level and diversified long-term care system for middle-aged and older adults.

Maintaining sustainable progress in knowledge and technology is essential in building a sustainable society. The transnational or transregional mobility of talents is one of the important channels for the flow and sustainability of knowledge and technology. Based on the social network theory, we attempt to investigate whether scholars’ mobility experience will effectively improve their future scientific research productivity. Empirical studies were conducted based on the academic curriculum vitae of faculties in a leading research university in China from 2008 to 2023. The results suggest that the mobility experience of scholars does not have a significant influence on the total number and quality of papers when we consider both domestic and international publications due to diversified publication channels in the social science disciplines. However, in terms of the number of papers published in international journals and international collaborations, the existence of mobility experiences in their past education or working experience has a significant positive impact on scholars’ later research productivity. In addition, scholars flowing through joint training programs at their doctoral phase tend to produce more co-authored papers. This research provides a reference for the wellbeing and sustainable productivity of university scholars, which is essential in higher education and social environments, and provides universities in developing countries with inspiration for building a sustainable academic talent flow system. It is important to note that this empirical study mainly focuses on researchers and publications in the social sciences, and the behavioral pattern and impact on research outputs might be different for scholars in the natural science disciplines. Due to the limitations with regard to data acquisition, this paper has not further discussed building an international academic network, which needs more in-depth research in the future.
