Cognitive ability plays a crucial role in adolescents' academic performance and subsequent career development. Although previous studies have demonstrated that physical activity, self-education expectations, and learning behaviors positively affect the cognitive development of adolescents, the extent of their influence and their mediating roles require further elucidation. This study is based on tracking survey data from 2,688 adolescents in Chinese households collected in 2018.

Article Synopsis
- Physical exercise significantly improves individuals' physical appearance, as evaluated by third-party assessments, showing a more objective measure compared to self-assessments.
- The study analyzed data from over 25,000 respondents and found that the positive effects of exercise on appearance vary among different groups, notably benefiting women, urban residents, and those with lower initial appearance scores the most.
- An interesting age-related trend emerged, highlighting that middle-aged adults (40-59 years) gain the most from exercise, while younger and older adults see lower benefits, illustrating an inverted U-shaped relationship between age and appearance improvements from exercise.
Background: Externalizing problem behaviors can significantly and negatively impact adolescents' learning, daily life, and future socialization. While physical exercise is believed to inhibit adolescents' externalizing problem behaviors, the extent of its effect and the mediating mechanisms remain unclear.
Methods: This study is based on data from the 2018 China Family Panel Studies (CFPS).
In traditional group decision making, the inconsistent experts are usually forced to make compromises toward the group opinion to increase the group consensus level. However, the strategy of reaching group consensus via an incentive mechanism encouraging adjustment of preferences is more effective than forcing, which is the aim of this article. Specifically, this article establishes a novel incentive mechanism to support group consensus under dynamic trust relationship.

- - This paper presents a novel method to help patients choose the best doctor for online consultations by using a decision-making approach that takes into account various correlated attributes from real patient data.
- - It employs a two-stage classification model using BERT to analyze text reviews and extract relevant service features, while incorporating both public and personal preferences through a 2-additive fuzzy measure.
- - The effectiveness of the proposed method is demonstrated through a case study on dxy.com, showing that it outperforms traditional multi-attribute decision-making methods in ranking doctors.
