The study aims to test the impact of risk on supply chain cooperation in the agriculture sector in Vietnam. The research paper used the quantitative research method through analysing structural equation modelling (SEM), with a dataset of 518 observations. The survey subject is the experienced and knowledgeable manager in supply chain management in the agricultural sector. The result found that risk has impacted not only directly and negatively on the supply chain cooperation but also indirectly through intermediary factors, namely commitment and the participant's opportunistic behaviour. In addition, the study has also proved that in some cases, the participant's dependency mentality in work and opportunistic behaviour lead to the opposite impact of commitment on trust and level of supply chain cooperation in agriculture. Based on this result, the study also makes recommendations to enhance the effectiveness of the supply chain cooperation in the agricultural sector in Vietnam. The findings contributed to both theory and practice. It pointed out the impact of risk on the supply chain cooperation in the agricultural sector, as well as the mediating role of commitment and opportunistic behaviour in this relationship.

The study aims to examine the impact of supply chain linkages on the performance of businesses. Quantitative research is used by implementing the analysis of the SEM linear structure model. A survey is conducted consisting of 598 samples - experienced managers who had the knowledge of the management of supply chain activities in enterprises in Vietnam. Research results show that supply chain linkages, although not having a direct impact, has an indirect impact on the business performance of enterprises through the intermediary factors of trust and business strategy and the opportunistic behaviors of the participating members. Also, research has demonstrated that opportunistic behaviors have negative effects on trust among members of the supply chain.

This study aims to examine the impact of brand image on public university links in the context of autonomy in Vietnam. Using quantitative research methods through exploratory factor analysis (EFA) and Structural Equation Modeling (SEM), the survey data included 631 samples of managers, experts, and scientists at public universities divided by different disciplines. The results of the study showed that the brand image has both a direct and indirect impact on public university links in the context of autonomy through intermediate elements of trust and commitment in the relationship between universities. In addition, trust has also been shown to have a direct impact on commitment in the relationship between public universities in Vietnam in the context of autonomy. In the context of research in Vietnam, the findings of this study have shown both theoretical and practical contributions and will be an important basis for further research.
