To analyze the relationship between variables, Pearson correlation and stepwise regression analysis were used. Findings show that, among the examined BE characteristics of children's places, only neighborhood greenness and proximity to polluting industrial facilities are significantly associated with PM<sub>2.5</sub> concentrations. Two additional factors are significantly associated with PM<sub>10</sub> concentrations: building density and land use mix.

In the presence of cost synergies, the scope for lower waiting times as a result of the merger is larger if the hospitals are more profit-oriented. This result is arguably confirmed by our empirical analysis, which is based on difference-in-differences estimations using a long panel of data on hospital merger in the English National Health Service (NHS). While we find that hospital mergers lead to higher waiting times on average, we also show that the effects of a merger on waiting times crucially rely on a legal status that can reasonably be linked to the degree of profit-orientation. Whereas hospital mergers involving Foundation Trusts tend to reduce waiting times, the corresponding effect of mergers involving hospitals without this legal status tends to go in the opposite direction.</div></div>","PeriodicalId":48409,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"238 ","pages":"Article 107196"},"PeriodicalIF":2.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It does this by exploring community struggles over land and labour in India's largest coalfield Korba in Chhattisgarh state. While the Indian government has announced that the country will have net zero emissions by 2070, continuing coal mine expansions built on the dispossession of rural poor and indigenous groups dramatically shape lives, economies and aspirations, and with them expectations around a potential transition away from coal. At the moment coal provides stability and continuity in the context of a depressed agricultural sector and limited non-farm employment opportunities. The coal sector is in this manner a source of hope and aspirations for many, while simultaneously creating enormous social and ecological disruptions. In the article we place specific focus on the interlinked roles of land and labour in the production of fossil-free futures situated within agrarian relations. Long-term resistance to land acquisition for coal mining is in recent years accompanied by the emergence of new relationships that coal communities are forging around land as a transactional asset, to be bartered for mining company jobs, or simply used as a speculative asset which may yield future pay-off as mining continues to expand. Based on a close reading of everyday micro-level negotiations, this paper argues that the possibilities for justice in a post-coal future is rendered complicated by existing coal economy dependencies and narrow conceptions of compensation.</div></div>","PeriodicalId":48384,"journal":{"name":"Energy Research & Social Science","volume":"127 ","pages":"Article 104304"},"PeriodicalIF":7.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the formulation of effective adaptation financing mechanisms presents a complex and formidable challenge. This study seeks to examine several critical elements within a typical adaptation financing framework, specifically focusing on green bonds, to assess their influence on the design of bond issuance cycle. We develop a continuous time model that integrates adaptation strategies with the financing process and perform a theoretical analysis of pivotal decisions involved in investment and financing, including the allocation of adaptation resources, financing and repayment structures, and issuance cycles. The model’s efficacy is subsequently validated through a case study on hydropower management. Furthermore, we conduct an empirical assessment of various key factors that influence the cycle of green bond issuance. Our theoretical findings indicate that an increase in the marginal utility of adaptation investment correlates with enhanced financing efficiency, necessitating that decision-makers adopt proactive financing strategies. Additionally, both heightened production efficiency and increased climate uncertainty are associated with extended bond issuance cycles. Our empirical analysis further reveals that the influence of bond interest rates on the issuance cycle is more pronounced in long-term bonds, potentially encouraging firms to pursue more preemptive adaptation strategies.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":"239 ","pages":"Article 108757"},"PeriodicalIF":6.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to integrate geostatistical techniques with unsupervised machine learning algorithms to classify zones of high, medium, and low potential for lanthanum (La) and scandium (Sc) in southern Ecuador. A database comprising 3998 geochemical samples was used, with concentrations estimated via Ordinary Kriging (OK), employing variogram structures tailored to each element. The K-means, Gaussian Mixture Models (GMM), Mini-Batch K-means (MBKM), and Spectral Clustering (SC) algorithms were applied to the interpolated values to achieve automated spatial segmentation. Validation against a traditional percentile-based classification yielded high accuracy, with SC (accuracy = 0.898) and KM (0.860) performing best for La, and GMM (0.899) for Sc. Additionally, total metal contents per zone were estimated, reaching up to 725.10 t of La (average grade: 11.98 mg/kg) and 103.23 t of Sc (average grade: 2.08 mg/kg) in medium-potential zones according to GMM and SC, respectively. Strong lithological associations were identified, particularly highlighting the JUB unit as key for scandium occurrence. Overall, the results confirm that the combination of kriging and unsupervised clustering enables effective classification of mineralogical domains with high spatial coherence, providing a robust tool for prioritizing target areas in early exploration stages.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"109 ","pages":"Article 105731"},"PeriodicalIF":10.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
