In the context of COVID-19 pandemic lockdowns, fitness influencers on social media are greatly involved in people’s home fitness processes, but there is limited research examining the role of fitness influencers on social media in exercise intention. This study aimed to explore whether people’s perceptions of the personal attributes and content quality of fitness influencers can promote a strong emotional connection between the two, thereby influencing people’s exercise intentions. Based on the theory of the parasocial relationship, we investigated the influence of social attractiveness (SA), physical attractiveness (PA), task attractiveness (TA), and content quality (CQ) of fitness influencers on the parasocial relationships (PSRs) between viewers and fitness influencers on social media and whether PSRs positively contribute to viewers’ exercise intentions (EI). The results revealed that SA, PA, TA, and CQ have positive influences on PSRs and CQ; PSRs directly contribute to EI; and PSRs have a mediating effect between EI and CQ. This study provides new insights into understanding the relationship between fitness influencers and people’s online fitness behaviors.

Along with the increasing trend of transactions occurring on social media, the consumption of Chinese cultural and creative products has increased even against the background of the COVID-19 pandemic. In this context, this article aims to analyze the relationships between virtual community-based social identity and cultural and creative product customer engagement (CE) behaviors. To this end, social identity theory and CE behavior theory were applied to previous research model. Structural equation modeling (SEM) was conducted using data from 520 self-administered questionnaires from online virtual community members. The results show that social identity has a significant effect on customer knowledge behavior, participation behavior, and influencer behavior. Moreover, influencer behavior mediates the effect of social identity on purchase intention. The study also identified gender differences in the mediation for influencer behaviors. Our results suggest that women are more sensitive to influencer behaviors than men, and thus generate more purchase behaviors.

This study aims to examine the impacts of community gardening on the daily life of residents and the management organisation of pandemic prevention in the context of the COVID-19 pandemic, a major public health scourge in 2020. The research team applied a participatory action research approach to work with residents to design and implement the Seeding Plan, a contactless community gardening program. The authors carried out a study to compare the everyday conditions reflecting residents’ mental health of the three subject groups during the pandemic: the participants of the Seeding Plan (Group A), the non-participants living in the same communities that had implemented the Seeding Plan (Group B), and the non-participants in other communities (Group C). According to the results, group A showed the best mental health among the three; Group B, positively influenced by seeding activities, was better than Group C. The interview results also confirmed that the community connections established through gardening activities have a significant impact on maintaining a positive social mentality under extraordinary circumstances. From this, the study concluded that gardening activities can improve people’s mental health, effectively resist negative impacts, and it is a convenient tool with spreading influence on the entire community, so as to support the collective response to public health emergencies in a bottom-up direction by the community.

Design thinking is the foundation of professional design education, and the shift from zero to professional design skill involves the completion of the transition from single-mindedness to independent and innovative thinking. In this exploratory study on design teaching, we build a novel teaching model by drawing on the connection between students' self-transcendent knowledge and formal knowledge in design thinking. Based on the Design for Happiness framework (DfH), this study uses Positive Emotional Granularity cards (PEG) to stimulate students to identify and categorize various positive emotions. We matched 15 furniture-related positive emotion keywords, summarized the corresponding design strategies, and subsequently generated Design for Happy Furniture cards (DfHF). We looked at new structural reorganizations of design teaching resources and effective teaching models and examples that might be used in course delivery. This study used the USE scale for quantitative analysis and triangulation for qualitative data analysis. The results indicate that this method is crucial for making it easier to convert design ideas into practice and for enhancing the efficiency of instructional techniques in a specific design procedure. The bottom-up approach is beneficial for creating sets of cards and design strategies, as well as for utilizing the cards in innovative ways to enhance students' creativity, engagement, and self-efficacy. DfHF cards are a valuable tool for promoting motivation and facilitating the constructive learning of creative skills. They not only improve students' creative thinking abilities but also expedite the design decision-making process and prioritize emotional integration and user well-being.

Background: Against the backdrop of population aging and the accelerated development of dementia-friendly communities, public stigmatizing attitudes toward dementia have emerged as a critical barrier to the social integration of affected individuals. To date, limited empirical research in China has examined the mechanisms linking dementia knowledge, contact, and stigmatizing attitudes (perceived stigma) across different age groups within indigenous community settings. This study, conducted as part of a pilot dementia-friendly community initiative in Shanghai, seeks to investigate intergenerational differences in dementia knowledge, contact experiences, and stigmatizing attitudes, and to examine the mediating role of contact in the relationship between knowledge and stigma, thereby contributing locally grounded empirical evidence to the field. Methods: A cross-sectional survey design was employed. A total of 397 community-dwelling residents aged 18 years and older in Shanghai participated in the study. Data were collected on sociodemographic characteristics, dementia knowledge, contact experiences with individuals living with dementia, and stigmatizing attitudes. Descriptive statistics and between-group analyses were used to compare age-group differences, and a mediation model was constructed to test the associations among dementia knowledge, contact, and stigma. Results: Significant intergenerational differences were observed in dementia knowledge, contact experiences, and stigmatizing attitudes. Middle-aged adults demonstrated higher levels of knowledge and more positive contact intentions; older adults reported the highest frequency of contact and the lowest levels of stigma; and younger adults exhibited the most pronounced stigmatizing attitudes. Mediation analysis further revealed that contact experience partially mediated the relationship between dementia knowledge and stigmatizing attitudes, suggesting that higher levels of dementia knowledge may be associated with reduced stigma through the facilitation of positive contact. Conclusion: Enhancing public knowledge of dementia and promoting positive contact with affected individuals may contribute to reducing social stigma and supporting the social inclusion of people living with dementia. This study further elucidates the pathway linking dementia knowledge and stigmatizing attitudes, identifying contact behavior as a significant mediator. The findings lend support to intervention strategies that integrate cognitive enhancement with structured contact initiatives, and provide preliminary evidence for age-specific community-based anti-stigma practices. It should be noted that the mediation pathway identified in this study is correlational rather than causal; moreover, as the sample was drawn from pilot dementia-friendly communities in Shanghai, the generalizability of the findings to other communities or regions may be constrained by variations in local support systems, public awareness, and aging profiles. Future research should adopt longitudinal or interventional designs to validate these findings across broader populations.

The immersive experience of holographic displays is fundamentally limited by their space–bandwidth product (SBP), which imposes an inherent trade-off between the field of view (FOV) and eyebox size. This paper proposes a method to extend the SBP by employing cascaded modulation with a dynamic spatial light modulator (SLM) and a passive high-resolution binary random phase mask (BRPM). We find that the key to unlocking this extension of SBP lies in a sophisticated algorithmic optimization, grounded in a physically accurate model of the system. We identify and correct the Nyquist undersampling problem caused by high-frequency scattering in standard diffraction models. Based on this physically accurate model, we employ a gradient descent optimization framework to achieve efficient, end-to-end solving for complex light fields. Simulation and experimental results demonstrate that our method achieves an approximately 16-fold SBP extension (4-fold FOV) while delivering significantly superior reconstructed image quality compared to the traditional Gerchberg–Saxton (GS) algorithm. Furthermore, this study quantitatively reveals the system’s extreme sensitivity to sub-pixel level alignment accuracy, providing critical guidance for the engineering and implementation of our proposed method.
