In this study, Partial Least Square – Structural Equation Modeling (PLS-SEM) was used to analyze data from the questionnaire survey of 363 customers who are familiar with live streaming platforms in Vietnam. By using SmartPLS for data empirical evaluation and hypotheses testing, research shows that the social presence of a live streaming platform and scarcity have a positive impact on consumer’s flow states, hence inducing consumers’ impulsive buying behaviors.

Low-rank representation (LRR) plays a significant role in image classification tasks due to its ability to capture the underlying structure and variations in image data. However, traditional low-rank representation-based dictionary learning methods struggle to leverage discriminative information effectively.

This research explores how customer engagement with the F&B brand’s dedication to social responsibility, sustainable business practices, and corporate governance influences impulsive buying. An online survey was requested, and a total of 322 participants were chosen for data analysis. To conduct statistical analysis, partial least squares structural equation modeling (PLS-SEM) was used with the SmartPLS3 program.

The study "A genre analysis of abstracts of MA theses in English Linguistics" explores to what extent the Vietnamese learners of English as a foreign language (EFL) apply the knowledge that they have formally learned in the Writing and the Doing scientific research courses to writing their MA graduation theses; the focus is on the abstract. From the perspective of genre analysis, this study aims to describe the structural features of this genre. Data for the investigation is 30 abstracts bounded in the master theses written in English by Vietnamese learners.
