This study is based on the stone artifacts of the Machang Culture in the Zhuanglang River Basin. By analyzing the relationship between lithic technology and economic patterns, and integrating considerations of regional environment and subsistence strategies, it explores the technological adaptation, resource utilization, and social development characteristics of Late Neolithic humans. Through field surveys, typological analysis, and other methods, the study reveals the relationship between the functions of stone artifacts and subsistence economy, elucidates the “coexistence of old and new” phenomenon in the Machang Culture of the Zhuanglang River Basin, and provides new perspectives for prehistoric cultural research in the Gan-Qing region.

As generative AI is increasingly integrated into emotionally intimate contexts, concerns about its reproduction of gender bias are growing. While existing scholarship has extensively explored static biases in dataset and model design, few studies have explored how gender stereotypes evolve and are reinforced through dynamic human-computer interactions. This study examines how emotionally sustained conversations with an AI agent (e.g., ChatGPT) gradually stabilize and amplify symbolic gender roles through ritualized discourse patterns. Drawing on the Computers as Social Actors (CASA) paradigm and Interactive Ritual Chaining (IRC) theory, this study explores how users co-construct relational expectations with AI systems over time. Using a two-stage corpus design containing eight participants, we compared lexical frames and emotional tones in the pre- and post-phases of intimate interaction. Results suggest that the AI's responses increasingly conformed to normative gender roles: women were positioned as emotional receivers, while men were shaped as resilience providers-even when expressing similar emotional needs. These findings highlight that dynamic biases are not only deeply ingrained, but also reinforced by the way they are interacted with, creating new ethical challenges for relational fairness in AI communication. By shifting the focus from static design issues to ongoing dialogic reproduction of gender meaning, this study contributes to a deeper understanding of algorithmic bias in virtual companionship.

Various social media platforms have offered digital spaces for every online user to express themselves and interact with others. In the participatory digital culture that consisted of a large number of interactive behaviors, some users have successfully made the transition from audience to curator. This transformation has become a typical trajectory of personal branding. Based on this path, this study proposes a generative predictive framework that integrates behavioral data modeling with trajectory inference to simulate individual brand development from passive consumption to active curatorship. We explored the relationship between participation, creative content, and branding construction by using Convolutional Neural Networks (CNNs), Transformers, and temporal modeling. By training on data from various platforms, the model can, to a certain extent, predict the development path of individuals from audience to curator, and demonstrate its adaptability across different platforms, which provides ordinary users a viable strategic reference to gain influence online and make true the personal branding.

Minilateralism has become a defining feature of the Biden foreign-policy doctrine to tackle security issues around the world especially in the Indo-Pacific region. Neoclassical realism, which determines security as the primary objective of all states and incorporates both external and internal variables, provides a more comprehensive perspective to analyze the influence of the international system on state behavior. Therefore, this essay will use the analytical framework summarized from Rose G.’s article Neoclassical Realism and Theories of Foreign Policy to analyze the underlying reasons, defining features and development trend of Biden’s minilateralism with a view to providing predictions and recommendations. The framework consists of 3 intervening variables. The first is “Relative Power”. The second is “Perceptions of Relative Power”, which includes “States’ perceptions” and “Decision makers’ perceptions”. The last is “State Power”, which includes “State apparatus” and “State-society relationship”.

Objective: Identify evidence-based interventions for sleep disorders in children with autism spectrum disorder (ASD) by analyzing their sleep behaviors and influencing factors. Methods: The study included 315 children with ASD are between the ages of three and seven, as well as 237 healthy children.The Children’s Sleep Habits Questionnaire (CSHQ), the Strengths and Difficulties Questionnaire (SDQ), and the 90-item Symptom Checklist (SCL-90) were administered. Results: Poor sleep quality was observed in 78.65% (218/315) of children with ASD. Furthermore, the CSHQ scores were compared between the two groups to see if there were any differences. The results indicated that children with ASD exhibited elevated levels of total and subscale scores related to sleep duration, nighttime awakenings, abnormal sleep, bedtime habits, sleep anxiety, and daytime sleepiness than the control group. A study was conducted on the ASD group using Pearson correlation analysis to examine all variables. The results showed that total emotional problems scores were positively correlated with sleep behavior; positive behavior was negatively correlated with sleep behavior; and total difficulty scores were significantly correlated with correlated with daytime sleepiness, sleep delay, and sleep duration. Parents of children with ASD and insomnia scored significantly higher on items such as obsessive-compulsive disorder, depression, and hostility compared to parents of children with ASD and normal sleep. Conclusion: Children with autism have significant sleep problems, and both parental mental health and children's problem behaviors influence sleep behavior in children.

Cultural and tourism short videos have emerged as a pivotal driving force in advancing regional cultural communication and tourism economic development. The tripartite characteristics they manifest—content diversification, rapid communication velocity, and audience interactivity—have fundamentally reconstructed the communicative ecology of the cultural and tourism sector. Notwithstanding, a constellation of issues has been exposed in their developmental trajectory, including ambiguous positioning of official accounts and content homogeneity, which have notably diminished communicative efficiency. Empirical studies indicate that in the current era dominated by the "traffic-oriented" paradigm, the absence of gate keeping functions resulting from insufficient supervision, coupled with the dissolution of cultural uniqueness caused by symbolic inflation, has generated unbalanced experiential outcomes for both localities and users. It is only through the following pathways that a healthy cultural and tourism communication ecology can be established and the high-quality sustainable development of the cultural and tourism industry can be realized: communicators must adhere to communication ethics and accept multi-stakeholder supervision to rebuild official public credibility; local cultures should be deeply excavated, discarding traffic-oriented templates to construct unique cultural and tourism images; and the service quality of cultural and tourism short videos should be enhanced to provide cultural and tourism guidance and information navigation for the public.

Retrofitting elevators in old residential buildings is a typical project in urban community renewal, yet it often falls into a collective-action dilemma due to conflicting interests. Using the elevator-addition project in Caihong Subdistrict, Guangzhou, as a case, this study explores how to activate community elites’ motivation to break this impasse. Through qualitative analysis, it proposes a threefold activation mechanism: (1) at the actor–structure level, build a polycentric governance network that integrates administrative, market, social, and elite forces to form a stratified action architecture; (2) at the institution–action level, design incentive-compatible rule instruments to lower coordination costs; and (3) at the value–interest level, combine quantified benefit assessments with moral incentives to generate a dual drive of instrumental (material) and value rationalities. The findings indicate that, under Party-building leadership, community elites’ “sense of mission as Party members” and “neighborly sentiment” are the core drivers. By flexibly deploying both formal and informal strategies, these elites effectively foster consensus. The study offers theoretical insights and practical approaches for grassroots governance and recommends promoting the “Chinese path” to address collective-action challenges in urban renewal worldwide.
