Using violent crime in public as an outcome, four models for each city are produced using a Risk Terrain Modeling approach. One using spatial data on place features from register data and one from OSM, one model with prior violent crime excluded and one with prior crime included. The results show that several place features are significantly associated with violent crime in public independent of using register or OSM data as input. While models using register data seem to produce more accurate and efficient predictions than OSM data for the two smaller cities, the difference for the largest city is negligible indicating that the models provide similar results. As such, OSM place feature data may be of value when predicting the spatial distribution of future violent crime in public and provide results similar to those when using register data, at least when employed in larger compared to smaller cities. Possibilities, limitations, and avenues for future research when using OSM data in place-based criminological research are discussed.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"18 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12061-024-09609-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It combines spatial concentration, spatial interaction, and spatial mismatch index to reveal the characteristics of the relationship between rural population and agricultural production space from a multi-gradient perspective. The results show that: (1) Rural population and agricultural production space show a reverse unbalanced “center-edge” structure, with rural population clustering in the urban area and agricultural production space spreading to the periphery, with a significant unbalanced distribution. (2) Rural population and agricultural production space show diversified relationship characteristics, with significant inconsistency in their spatial concentration, overall low spatial interaction, and obvious spatial mismatch index, which greatly affects the rational utilization of human resources and land resources. (3) The characteristics of the relationship between rural population and agricultural production space are influenced by natural endowment, economic development level, and location conditions, showing a multi-gradient differentiation pattern.

We constructed a dependency network of land use intensity from the perspective of spatial connection, and summarized the spatiotemporal evolution patterns of urban agglomeration combined with social network analysis methods. The results indicate that: (1) From 1980 to 2020, both land use intensity and spatial connection strength in the GBA have significantly increased, though the characteristics of different cities varied noticeably; (2) The spatial connection center of the urban agglomeration has shifted geographically from Hong Kong and Macao to the Pearl River Delta, and then to the east bank of the Pearl River.

This paper proposes a novel framework, eRurban, that utilizes machine learning to automate village ranking and analysis for rural development in India. eRurban leverages data from 250,000 gram panchayats (village clusters) to group villages with similar development trajectories through clustering techniques. A key innovation is the introduction of the ClusterRank algorithm, a novel ranking method that utilizes gradient descent to train ranking coefficients for improved accuracy and efficiency. The effectiveness of ClusterRank is demonstrated by its high Spearman correlation coefficient (0.89) when compared to village rankings generated by SPMRM reports. This cost-effective framework offers valuable insights and guidance for rural development planning in India.

In this study, the rapid development city of Xi’an, China was employed as the case study, and the Gaussian-based 2SFCA method was utilized to measure the spatial distribution of high-level healthcare accessibility by private cars and public transit. The change in accessibility could be obtained by quantifying the difference in accessibility before and after establishment of the new hospitals. Furthermore, the improvement in equity in healthcare accessibility was measured using the Gini coefficient. Finally, the contribution of each new hospital to healthcare accessibility was evaluated from the perspectives of population coverage, average improvement of each bed, and improvement of the Gini coefficient. The results show that the areas with significant improvement are scalloped to the periphery of the study area, especially in the communities near the new hospitals.

The final part of the analysis assesses the relationship of these risk scores to macro level measures of social disorganization in determining their differential impact on food access. The results of this study suggest that high-risk environments for aggravated assaults and the presence of abandoned properties are strongly associated with the distribution of food access. In addition, individuals who are going to bodegas to get food within food deserts are also increasing their risks of becoming victims of aggravated assault.

The primary innovation of this analysis is its capacity to monitor shifts in spatial patterns of poverty over time, providing a dynamic perspective essential for comprehending and addressing non-static processes. We discovered that the majority of US counties exhibit consistent poverty trends, characterized by either persistent or intensifying hot spots (clusters of high poverty) or cold spots (clusters of low poverty), with only a minority experiencing recent changes in poverty trajectories. The choice of spatial scale significantly influences these trends. Our intersectional analysis of poverty with age and race demonstrated that the categories of children and adults have a markedly higher number of counties with persistent and intensifying hot spots compared to the elderly category. Nonetheless, the elderly category has a greater number of new emerging hot spots. Furthermore, our exploration of the interaction between race and poverty dynamics showed that the spatial patterns of emerging poverty hot spots vary among racial groups and do not align with their population distributions.

Public service facilities, especially medical services, are crucial for the well-being of rural residents. Essential for achieving balanced development and improved living standards, these services must ensure equitable access in rural areas, balancing social justice with humanitarian considerations. A comprehensive examination of their availability and interaction with the living circle is key to optimizing these facilities for balanced progress. This study focused on Qin'an County, Gansu, China, where it mapped out living circles based on residents' travel habits and the levels of medical institutions. It analyzed the distribution and accessibility of medical facilities within these circles, investigating their correlation with circle radii. The findings were aimed at enhancing the spatial layout of medical services, yielding three key insights: (1) The spatial layout of rural medical facilities in Qin'an County shows a \"core–edge\" trend, with most areas by low accessibility, in contrast to the high accessibility in the urban center. (2) A significant negative correlation was identified between the accessibility of medical facilities and the radius of the living circle; in other words, greater accessibility corresponds to a smaller living circle radius. (3) The K-means clustering algorithm proved to be an effective method for optimizing the accessibility of medical facilities, leading to improved access and more balanced distribution across living areas. In China's new stage of development, understanding the complex dynamics of the \"people-land\" relationship is crucial.

The geostatistical approach was initially applied in a simulated data with patterns known a priori: random and clusters. Then it was validated with real data of roasted coffee industry in Minas Gerais, Brazil. Each dataset was tested in isotropic and anisotropic scenarios. Geostatistics was sufficient to detect patterns of randomness and spatial dependence, measure the extent of proximity between firms, identify regions with a high level of industrial concentration on the map and estimate an index of concentration at the firm level. The results also advanced the specialized literature by indicating that the anisotropic scenarios, which adjusts the directional bias, better described the reality of the phenomena compared to the isotropic ones. Error measures in anisotropic scenarios were between 7 and 30% more accurate. It was concluded that the direction can be a determinant of the theory of agglomerations and that geostatistics can be useful for mapping potential industry clusters.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"17 4","pages":"1703 - 1724"},"PeriodicalIF":2.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142413463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
