Summary: This paper proposes a novel adaptive marker segmentation graph convolutional network (AMS-GCN) for aspect-level sentiment analysis. The AMS-GCN model enhances the information capacity of words by merging marker information from two datasets and divides different marker information into separate modules. The model employs bi-syntax-aware and semantic auxiliary modules to capture syntactic and semantic information, and the aspect-related graph aggregates sentiment information of different aspects. Experimental results show that the proposed model achieves state-of-the-art results on several benchmark datasets.

Summary: This study compared the influencing factors of youth engagement in waste sorting and recycling in Shenzhen, China and Turku, Finland, finding a clear consistency between youth's intention and behavior in both cities. Key influencing factors in Shenzhen included subjective norms, knowledge, and perceived behavioral control, while in Turku, compatibility was the top determinant with subjective norms having the least influencing power. Additionally, lower compatibility did not necessarily hinder youth participation in WSAR practice in Turku.
