The little black dress (LBD) has evolved from a minimalist garment introduced by Chanel into a powerful cultural symbol that reflects the transformation of female consciousness throughout modern history. This paper investigates the semantic, cultural, and ideological meanings embedded in the LBD across different periods, focusing on how its changing design aesthetics mirror shifting perceptions of femininity, empowerment, and social identity. By analyzing visual materials, fashion designs, artworks, and advertisements from the Victorian era to contemporary popular culture, the study demonstrates that the LBD has been repeatedly reinterpreted as a site where gender norms are challenged, reconstructed, or reclaimed. The evolution of the LBD—from mourning attire to modernist neutrality, to a signifier of elegance, and finally to a medium of personal agency—reveals broader societal transformations regarding women’s autonomy and self-expression. Ultimately, the LBD functions not only as a fashion item but also as a semiotic vehicle documenting the progress of women’s roles and rights in society.

Background: Prior reviews indicate mindfulness-based interventions (MBIs) alleviate PTSD symptoms through fear extinction and cognitive restructuring, yet critical gaps remain in clarifying their neural mechanisms. Objective: This systematic review integrates empirical evidence on the neural correlates of standardized MBIs (e.g., MBSR, MBCT) in ameliorating core PTSD symptoms (intrusions, avoidance, and negative cognitions) to inform clinical translation and future research. Method: The review systematically searched PubMed, Web of Science, and Google Scholar (2015–2025) for English-language studies examining neurobiological mechanisms of MBIs for PTSD, using terms PTSD, mindfulness interventions, and neurobiological measures. Results: MBIs reduced intrusive symptoms by regulating limbic hyperactivity, enhancing prefrontal control over traumatic memory activation, strengthening amygdala-prefrontal connectivity, and attenuating autonomic reactivity. For avoidance behaviors, MBIs increased insular and temporoparietal junction (TPJ) activation during emotion regulation, restored connectivity between default mode, salience, and executive control networks, and modulated FKBP5 methylation to optimize hypothalamic-pituitary-adrenal (HPA) axis function. MBIs alleviated negative cognitions by optimizing neural oscillations (theta, alpha) and cortisol dynamics, reducing hypervigilance and cognitive rigidity.

The rapid advancement of artificial intelligence technologies has propelled cognitive intelligence (CI) into becoming a pivotal force reshaping production modes, dissemination mechanisms, and business models within the cultural industry. Grounded in the theoretical framework of cognitive intelligence, this study employs multidimensional empirical analysis to demonstrate that while significant progress has been achieved in applications spanning cultural content generation, personalized dissemination, immersive experiences, and global cultural outreach, three-dimensional challenges persist across the technological, ethical, and institutional domains. These include: (1) the misalignment between algorithmic capabilities and the essence of humanistic creation, resulting in deficient emotional expression, (2) ambiguities in rights attribution triggering copyright disputes, and (3) existing regulatory frameworks lagging behind digital cultural production paradigms. To address these constraints, this research innovatively proposes a tripartite synergistic optimization pathway encompassing cognitive, cultural, and technological dimensions. By expanding cognitive paradigms, enhancing technology-enabled empowerment, ensuring institutional adaptability, and deepening stakeholder collaboration, this approach ultimately facilitates the cultural industry’s paradigm shift from efficiency-driven enhancement to humanistic value-led high-quality development. The study further emphasizes that advancing the intelligent transformation of the cultural industry necessitates strengthening technology-driven innovation, refining institutional support mechanisms, and constructing a collaborative and mutually beneficial ecosystem to realize the deep integration and sustainable innovation of cultural technologies.

Under the policy background of digital transformation, the issue of multi-subject collaboration in grassroots smart governance has become the key to improving governance efficiency. This article applies the Actor Network Theory (ANT) and takes the “Quancheng Office” platform in J city as the research object to systematically analyze the construction path and practical effectiveness of its multi-subject collaboration mechanism. Research has found that grassroots smart governance requires the integration of heterogeneous actors through translation, forming a governance network that synergizes technology and institutions. Further research reveals the current practical difficulties and proposes optimization paths, providing a reference for the theory and practice of grassroots smart governance.

The proliferation of deepfake content on social media in recent years has posed significant threats to both individual and societal security. Consequently, devising effective countermeasures to curb the spread of deepfake information has become a critical challenge for social media platforms worldwide. This study aims to explore the propagation dynamics of deepfake information and evaluate the efficacy of various countermeasures by constructing a multi-agent model that integrates the SIR epidemiological model with the BA scale-free network theory. The research focuses on three distinct social media platforms in China—Douyin, Weibo, and Bilibili—as case studies. Through a series of simulation experiments, we compare the propagation patterns of deepfake content and analyze the performance differences of various countermeasures. The results indicate that, in terms of preventing the dissemination of deepfake information, the “preemptive defense” mechanism (exemplified by Douyin) proves to be the most effective in limiting the spread of deepfakes and ensuring timely counteractions. In contrast, the “post-verification” framework (exemplified by Weibo) is particularly effective in enhancing immunity against deepfake content. However, countermeasures based on self-media strategies that emphasize “emotion, viewpoints, and stances” (exemplified by Bilibili) demonstrate higher infection rates, weaker immunity, and longer response delays. The findings of this study offer valuable insights for developing more efficient and adaptive information governance strategies.

Against the dual background of implementing the fundamental task of fostering virtue through education and cultivating and developing new-quality productive forces, constructing an ideological and political education community for postgraduates has become an important direction for the reform of higher education. Focusing on colleges and universities in Heilongjiang Province, this paper combines the Marxist community thought and the concept of “whole-process, all-round, and all-staff education” to construct a “five-in-one” framework of the postgraduate ideological and political education community, which includes “value synergy, subject synergy, curriculum synergy, process synergy, and environment synergy.” By analyzing the practical difficulties faced by colleges and universities in Heilongjiang Province, such as the uneven distribution of ideological and political education resources for postgraduates and insufficient subject collaboration, this paper discusses the construction logic and implementation strategies of the postgraduate ideological and political education community in colleges and universities of Heilongjiang Province from three dimensions: theoretical foundation, practical expansion, and guarantee mechanism. It aims to provide references for promoting the high-quality development of postgraduate talent cultivation in the Northeast Old Industrial Base.

Liu Liangcheng’s first prose collection, A Village of One’s Own, was published in 1998 and quickly attracted widespread attention in the literary circle. In this work, assuming the identity of a “rural philosopher”, he employs a multitude of animal imageries to convey his unique insights into life. Particularly, the imagery of dogs occupies a prominent position in the text. It not only showcases his distinctive artistic style but also profoundly embodies the depth of his thoughts. Through diverse narrative techniques and the interweaving of memories and reality, Liu Liangcheng depicts the rich and three-dimensional life of dogs. Meanwhile, via this imagery, he presents the close yet complex relationship between animals and human life. Additionally, influenced by the geographical and cultural features of the borderland, Liu Liangcheng also reveals in-depth reflections on bioethics and the human living condition. These reflections encompass the relationship between humans and all things in nature, with “dogs” serving as a vivid carrier.

With the increasing aging of society and the advancement of medical technology, hospice care—a medical service model aimed at improving the quality of life—has gradually attracted widespread attention. In hospice care, volunteers play an extremely important role, providing abundant support and care to patients and their families. However, the quality and training level of volunteers directly affect the effectiveness of hospice care services and their social recognition. To meet the growing demand for hospice care, it is particularly important to establish a sound volunteer training system. Focusing on the construction of the “hospice care volunteer training system”, this paper applies the heuristic thinking of Bandura’s Social Learning Theory to explore its role and significance in the process of constructing the hospice care volunteer training system.

With the advent and continued development of the internet era, influencer cities have leveraged the internet’s power for rapid marketing, resulting in a swift rise to fame and a substantial influx of attention and traffic. In the face of such “overnight wealth and fame”, the primary challenge lies in preventing the transient nature of popularity and the potential lack of long-term sustainability, while simultaneously promoting enduring prosperity and fostering the high-quality development of the cultural and tourism industry. It is argued that sustained success can be achieved by influencer cities through strategies such as creating unique and immersive tourism experiences for visitors, enhancing infrastructure, facilitating upstream and downstream linkages, empowering technological advancements, and improving accessibility.

This research examines the complex role of Guochao, China Chick, in contemporary Chinese cultural production, moving beyond simple binary evaluations of its effectiveness. Employing the “Culture on Display” framework, this paper analyzes cultural economy performances at the micro level to explore how Guochao leverages consumer imagination and multiple interpretations to reconstruct “Invented Traditions.” This study reveals how deliberately reducing authoritative narration (“Authority Minus the Author”) creates spaces for interpretation that engage readers as active participants in creating meaning. The findings show that this process breaks down predetermined meanings and national narratives, transforming cultural production into both public exhibition and market product. We conclude that this transformation helps Guochao emerge as a powerful carrier of nationalist discourse, enhancing the understanding of contemporary cultural nationalism and consumer behavior.
