研究主题：社交媒体沉浸式广告对 Z 世代消费者购买意愿的影响
Discussion
This study aimed to explore how immersive social media advertising influences the purchase intention of Generation Z consumers in the fast-fashion industry. The core finding revealed that immersive interactive advertising exerted a significantly positive effect on consumers’ purchase willingness, with perceived entertainment value acting as the primary mediating variable, which fully verified the research hypothesis proposed in this study.
The research result is consistent with Li and Wang (2023), who also confirmed that experiential online advertising could strengthen consumers’ emotional attachment to brands. This study further expands existing research by distinguishing passive browsing ads from interactive immersive ads, explaining why traditional image advertising has gradually lost marketing effectiveness among young consumer groups. From a theoretical perspective, this research supplements the application of the Stimulus-Organism-Response (SOR) model in short-video platform marketing. Practically, fashion brands can optimize advertising delivery by designing interactive, game-based short-video content instead of rigid product promotion.
Several limitations exist in this research. First, the sample was only collected from young consumers aged 18–25 in first-tier cities, which cannot represent the consumption characteristics of Generation Z in lower-tier cities. Second, this study did not take brand familiarity as a moderating variable, which may affect the robustness of the mediating effect. Future research can expand the sample range to cover multiple city levels and add brand cognition, price sensitivity as regulatory factors to conduct in-depth heterogeneous analysis. In general, this study provides empirical reference for enterprises to formulate social media digital marketing strategies.

研究主题：被动刷社交媒体与青少年自尊水平的相关性研究
Discussion
The current research investigated the correlation between two modes of social media usage and adolescent self-esteem. Results showed that passive scrolling behaviour was significantly negatively correlated with self-esteem, while active interactive posting and comment had no obvious correlation with adolescents’ self-evaluation, which answers the core research question of this paper.
This conclusion supports the research of Valkenburg et al. (2017), who proposed that upward social comparison is the key psychological mechanism behind low self-esteem caused by social media. Unlike previous studies that only discussed total social media usage duration, this research subdivides usage behaviours, which clarifies that the harm of social media to teenagers does not lie in usage time, but in passive content browsing. Schools and families can carry out mental health education to guide teenagers to participate in online social interaction actively rather than simply browsing others’ refined life content.
There are two main limitations of this cross-sectional study: causal inference cannot be obtained only through correlation analysis, and all questionnaire data rely on participants’ self-report, which may lead to social desirability bias. Longitudinal tracking research can be adopted in follow-up studies to verify the causal relationship between passive social media use and self-esteem, and combine interview qualitative data to enrich the research conclusion.

研究主题：线上混合式教学对留学生课堂参与度的作用研究
Discussion
Based on semi-structured interviews with 22 international students, this study explored the influencing factors of students’ classroom engagement under hybrid online-offline teaching mode. The thematic analysis found that flexible course replay function, interactive online group tasks and teachers’ timely feedback are three core factors improving international students’ learning participation.
The research extends Lehmann’s (2014) theory of learning adaptation: overseas students no longer only adapt to learning rules passively, but rely on flexible online teaching tools to reduce language and cultural adaptation pressure. Previous overseas education studies mostly focused on offline classroom adaptation difficulties, while this study proves that digital teaching tools can effectively reduce the study-abroad adaptation cost of international students. For universities, extending the open time of course playback and designing more collaborative online assignments can effectively improve the retention rate of international students.
As the research sample was selected from a single comprehensive university in the UK, the research conclusion has transferability rather than universal representativeness. Future research can select universities of different types and disciplines to conduct comparative research, and explore the differentiated effects of hybrid teaching on students from different cultural backgrounds.

研究主题：基于改进算法的电商用户消费预测模型优化研究
Discussion
This study improved the traditional XGBoost algorithm by introducing feature dimensionality reduction processing, and the experimental results demonstrated that the prediction accuracy of the improved model increased by 7.2% compared with the original algorithm, which achieved the expected research optimization goal.
The experimental conclusion is consistent with Smith’s (2022) research on user feature optimization; this study further optimizes the feature screening threshold, effectively solving the overfitting problem caused by redundant user behaviour features in big data prediction tasks. The improved algorithm can be applied to e-commerce precise recommendation, user churn prediction and other business scenarios, helping enterprises reduce the cost of user operation.
The main limitation of this research is that the training dataset only covers user consumption data within one year, lacking long-term sequential feature verification. In addition, the algorithm is only verified on e-commerce datasets, and its adaptability in financial, logistics and other fields needs further testing. Subsequent research can use multi-year time-series datasets to train the model and conduct cross-domain algorithm verification to further improve the generalisation ability of the improved model.
