The results show that ALUE has exhibited a fluctuating downward trend over time, with southern regions performing better than northern ones. RDP significantly hinders improvements in ALUE, and this relationship remains robust after a series of robustness and endogeneity tests. Mechanism analysis reveals that cropland abandonment, scale operation, and cultivation structure serve as mediating factors in the impact of RDP on ALUE.

This study adopts Video Panoramic Segmentation (VPS) and uses walk-through video data alongside a TabPFN+SHAP deep learning regression model to examine how both static proportions and dynamic variation patterns of landscape elements relate to park popularity. The findings show that (1) dynamic features—such as amplitude, frequency, period, slope—exhibit stronger correlations with popularity than static composition ratios; (2) a novel methodological framework is proposed for dynamic VIA using VPS, Maximum Information Coefficient (MIC), and TabPFN; (3) Lower variation cycles for elements such as vegetation, roads, sky, grassland, and buildings are associated with higher park popularity. The frequency of these variations should not exceed 1.0 occurrences per minute, with an optimal value around 0.5 occurrences per minute; (4) Dispersed distribution of elements such as buildings and water bodies is preferable to concentrated arrangements. The accessibility of service facilities exerts a substantial influence on park popularity and (5) This study confirms that variations in the visual environment exert a more significant influence on park popularity than static visual features.

AOP has been linked to an increased risk of cognitive impairment, while impaired cognition may also elevate vulnerability to AOP. However, to date, no study has reviewed these relationships in both directions, particularly their potential bidirectionality. Thus, we conducted a scoping review to summarize and critically evaluate the existing studies examining the relationship between AOP and cognitive functioning. We searched four databases (Social Work Abstract-Academic Search Premier, PAIS Index, APA PsycINFO, and PubMed) for English peer-reviewed observational articles published from database inception through June 4, 2024. Eligible studies examined associations between at least one domain of cognition and AOP. Of the 3,817 records identified, 29 articles (23 cross-sectional, 6 longitudinal) using 27 unique studies met the inclusion criteria. Overall, most studies reported negative associations between AOP and cognitive functioning in both directions, suggesting a possible bidirectional relationship. Specifically, 14 of the 19 articles examining cognitive impairment as a risk factor for AOP reported a significant association between lower cognitive functioning and increased risk of AOP. In the reverse direction, 8 of the 10 articles found that higher AOP was significantly associated with poorer cognitive outcomes. Future longitudinal studies are needed to test the potentially bidirectional relationship between AOP and cognition and to explore the underlying mechanisms, thus informing integrated policies and interventions to concurrently promote cognitive health and address AOP among older adults.","PeriodicalId":54211,"journal":{"name":"Trauma Violence & Abuse","volume":"101 1","pages":"15248380251375481"},"PeriodicalIF":6.4,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In areas such as urban squares, the frequency, duration, and spatial distribution of interpersonal encounters reflect how effectively a space facilitates social interactions within the urban land system. However, these interactions—often brief and subtle—are difficult to observe and quantify in dynamic environments using conventional planning tools, limiting the proper management and design of urban spaces. To address this gap, this study proposes a human-centred, AI-based video analytic approach using computer vision techniques to detect and quantify social interactions. Interactions are classified into four categories—transient, sustained, long-term, and gathering—based on proximity and temporal thresholds, and are analysed in relation to spatial configurations, such as seating, greenery, and visual landmarks. A Social Interaction Intensity Index (SIII) is introduced to evaluate the capacity of different spatial zones to foster social activity, based on identified interaction points and their duration, normalized by area for fair comparison across zones. Rather than interpreting behaviour semantically, the index provides an objective and scalable indicator of how effectively urban land supports social functions and public life. This framework bridges data-driven sensing and human-centred land use policymaking, enabling planners and decision-makers to identify socially underperforming zones, guide spatial reconfiguration, and promote inclusive, evidence-based regeneration strategies that uphold humanistic values in public space design.</div></div>","PeriodicalId":17933,"journal":{"name":"Land Use Policy","volume":"159 ","pages":"Article 107818"},"PeriodicalIF":5.9,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As cropland carbon budgets gain importance in climate governance, balancing food production with emissions mitigation and carbon sequestration has become an urgent challenge. This study proposes a novel theoretical framework for horizontal carbon compensation for cropland use (HCCCU), which aims to promote equitable, efficient, and sustainable agricultural carbon governance in China. Using the city-level data, we analyze the spatiotemporal dynamics of cropland carbon budgets, evaluate the effects of regional disparities on compensation outcomes, and assess the feasibility and effectiveness of the mechanism of HCCCU. Our findings reveal a peak-then-decline trend in cropland emissions nationwide, while carbon sequestration has shown a steady growth trend. Southern regions exhibit higher emissions, particularly in major grain-producing areas, which serve as key emission hotspots. After adjusting for regional disparities, emission and sequestration allowances decreased in the south while increased in the northeast, reflecting significant spatial inequalities. The adjusted HCCCU demonstrates that major grain-producing areas are primary beneficiaries of compensation, with the cumulative compensation amount closely aligned with the estimated compensation needs. This equilibrium underscores the critical importance of accounting for regional disparities to ensure equity. Key contributors to compensation include Sichuan-Chongqing, North China, southeast coastal areas, and economically advanced cities, while the central part of northeastern, and northern border regions are identified as priority beneficiaries. Overall, this study offers a theoretical foundation and practical guidance for implementing the scheme of HCCCU, supporting regionally differentiated strategies for equitable emission reductions and sustainable cropland management.</div></div>","PeriodicalId":17933,"journal":{"name":"Land Use Policy","volume":"159 ","pages":"Article 107820"},"PeriodicalIF":5.9,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
