Social network theory is an important paradigm of social structure research, which has been widely used in various fields of research. This paper reviews the development process and the latest progress of social network theory research and analyzes the research application of social network. In order to reveal the deep social structure, this paper analyzes the structure of social networks from three levels: microlevel, mesolevel, and macrolevel and reveals the origin, development, perfection, and latest achievements of complex network models. The regular graph model, P1 model, P2 model, exponential random graph model, small-world network model, and scale-free network model are introduced. In the end, the research on the social network structure is reviewed, and social support network and social discussion network are introduced, which are two important contents of social network research. At present, the research on social networks has been widely used in coauthor networks, citation networks, mobile social networks, enterprise knowledge management, and individual happiness, but there are few research studies on multilevel structure, dynamic research, complex network research, whole network research, and discussion network research. This provides space for future research on social networks.

This study evaluated the dimensionality and psychometric properties of the Brief Self-Control Scale (BSCS) using a sample of university students in mainland China. Nine hundred and three students from a Chinese university participated in this study. The internal consistency, criterion validity, factorial validity and construct validity of the scale were examined. The Chinese versions of the BSCS demonstrated good internal consistency. The BSCS also showed significant moderate correlations with other construct-related scales. Exploratory factor analysis and confirmatory factor analysis suggested that only a modified 11-item BSCS with a four-factor structure was a good model fit in the sample of Chinese university students. The implications for research and theoretical development are discussed.

This review aimed at investigating the related studies on English as a foreign language teachers’ self-assessment and its role in their self-efficacy and self-regulation. Earlier investigations have proved that teacher self-assessment was significantly correlated with self-regulation. Moreover, studies showed that self-assessment and self-regulation enabled teachers to consider their teaching effectiveness, and they were important components of formative assessment. Earlier studies showed that self-assessment raised learner awareness and increased self-efficacy significantly through the improvement of mastery experiences. Furthermore, the study presented the implications and future directions of this line of research for different people, such as EFL teachers, teacher educators, and foreign language scholars. The ideas can improve their awareness of teacher self-assessment, self-regulation, and self-efficacy in educational contexts.
