A city's digitalization degree refers to the extent to which digital infrastructure and products can empower local industries and residents. Existing studies about the influence of digital technologies and products on health behaviors are mainly individual-level studies. Extant city-level studies primarily investigate the influence of cities' digitalization degrees on economic and environmental factors. There is a lack of city-level study examining the impact of cities' digitalization degrees on residents' health behaviors.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Method&lt;/h3&gt;&lt;div&gt;This study constructs a panel dataset comprising the data of 289 prefecture-level or above cities in China in the period from 2020 to 2023. Regression models are employed to examine the relationship between cities' digitalization degrees and residents’ health behaviors. Based on geographic locations, cities are sorted as “eastern or middle cities” and “western cities”. According to the concentration level of economic and social resources, cities are sorted into “central cities” and “non-central cities”. Based on these two categorizations, the heterogeneity of the main effect is also investigated. Furthermore, the average slopes and the dummy variable indicating whether a city is selected by the “Broadband China Strategy” are utilized as instrumental variables to address the endogeneity caused by omitted variables.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;In the basic regression model, cities' digitalization degrees show significantly positive relationship with residents' health behaviors (β&lt;sub&gt;1&lt;/sub&gt; = 0.178, 95 % CI [0.042, 0.315], p = 0.011; β&lt;sub&gt;2&lt;/sub&gt; = 0.841, 95 % CI [0.458, 1.225], p &lt; 0.001). The result is robust in the regression models using instrumental variables. Heterogeneity analysis indicates that for “eastern and middle cities”, there is a significantly positive relationship between cities' digitalization degrees and residents' health behaviors (β&lt;sub&gt;1&lt;/sub&gt; = 0.251, 95 % CI [0.105, 0.396], p = 0.001; β&lt;sub&gt;2&lt;/sub&gt; = 0.986, 95 % CI [0.512, 1.459], p &lt; 0.001), while this relationship is not significant for “western cities” (β&lt;sub&gt;1&lt;/sub&gt; = 0.032, 95 % CI [-0.176, 0.242], p = 0.759; β&lt;sub&gt;2&lt;/sub&gt; = 0.500, 95 % CI [-0.138, 1.139], p = 0.123).

Many countries are already transitioning to less environmentally harmful healthcare. This study investigates whether the two duties come into tension when designing new green hospitals and how such tensions (if found to eventuate) are navigated in practice. We conducted case study research in collaboration with an Australian hospital network, with one of the network's new public hospital builds comprising our case of focus. We undertook semi-structured interviews between March and June 2023 with those responsible for making design decisions in relation to the new public hospital being built. We analysed interview data thematically and report three main themes: separating the clinical and the environmental; tensions; and addressing tensions. We conclude by providing analysis of what is at stake in identified tensions using theories of justice, offering lessons that can help other hospitals mitigate against such tensions arising, and considering whether and when the moral reasoning employed in the case-under-study should be used to navigate the tensions. This study provides those responsible for green hospital design with a better understanding of what tensions they are likely to encounter between health, social, and environmental goods and how to reduce those tensions' occurrence. That understanding will help them to identify and avoid such tensions in their practice, but further work is needed to develop ethical guidance on how they should navigate the tensions when they occur.</div></div>","PeriodicalId":33615,"journal":{"name":"Global Transitions","volume":"8 1","pages":"Pages 181-192"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146187480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While prior research has examined individual drivers of environmental degradation in advanced economies, there remains a critical gap in understanding the integrated roles of artificial intelligence (AI), financial accessibility, and government effectiveness in mitigating ecological pressures, particularly through comprehensive panel data analysis in the G-7 context. This study addresses this gap by exploring how these factors influence environmental sustainability across G-7 nations, using the ecological footprint as a key indicator from 2010Q1 to 2022Q4. Employing the Panel Mean Group Autoregressive Distributed Lag model as the primary estimator, with Augmented Mean Group and Common Correlated Effects Mean Group estimators for robustness, the empirical results reveal that economic growth and urbanization significantly exacerbate ecological degradation in both the long and short run. Conversely, AI innovation, financial accessibility, and effective governance substantially reduce environmental impacts. These findings advance the discourse on Sustainable Development Goals (SDGs), especially SDG 9 (Industry, Innovation and Infrastructure), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). To foster a sustainable transition, policymakers should prioritize investments in AI-driven green technologies to optimize resource efficiency, expand inclusive financial mechanisms to fund eco-innovations and renewable projects, and implement governance reforms that enforce stringent environmental regulations in G-7 economies.</div></div>","PeriodicalId":33615,"journal":{"name":"Global Transitions","volume":"8 1","pages":"Pages 166-180"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145975961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess how motivational and socio-political factors predict the public sphere environmental behaviors, and to evaluate how motivational factors (e.g., norms, attitude, and environmental concerns) and socio-political factors (e.g., social and institutional trust) are associated. The target population is well-educated people living in Bangkok city of Thailand as their active participation in the behaviors can powerfully encourage other entities or organizations to act environmentally. Questionnaire surveys were conducted with 540 well-educated residents living in Bangkok city. First, model measurement was assessed via confirmatory factor analysis; subsequently, a path analysis was performed to test causal associations among the variables predicting public-sphere environmental behaviors. The results revealed that social and institutional trust were significantly associated with a motivational factor (the attitude toward public sphere environmental behaviors) and the attitude could subsequently predict the behaviors. There were also significant associations between motivational factors, and these associations had a significant power to explain public sphere environmental behaviors. Both social norms and personal norms were significantly associated with the attitude. Social norms could also significantly predict the behaviors, but personal norms could not. Personal norms had only an indirect influence on the behaviors via the attitude. Moreover, local environmental concerns were a weak predictor as they had only a significant indirect influence on the behaviors via the attitude. Global environmental concerns could directly and indirectly predict the behaviors. Thus, educating the public with global environmental issues and promoting the attitude and social norms could be powerful in promoting public sphere environmental behaviors. To promote a positive attitude towards the behaviors, both institutional and social trust could play an important role.</div></div>","PeriodicalId":33615,"journal":{"name":"Global Transitions","volume":"8 1","pages":"Pages 129-143"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sarcopenia, an important contributor to frailty, functional decline, and disability in older adults, remains underdiagnosed due to the inconvenience of standardized assessment tools and the lack of validated anthropometric thresholds for specific populations.</div></div><div><h3>Methods</h3><div>We conducted a cross-sectional study involving 416 community-dwelling individuals aged ≥60 years in Can Tho, Vietnam. Sarcopenia was diagnosed based on the Asian Working Group for Sarcopenia 2019 (AWGS 2019) criteria. Receiver operating characteristic (ROC) curve analysis was used to identify optimal cutoff values for body mass index (BMI), calf circumference (CC), arm circumference (AC), and waist circumference (WC), with the Youden index applied to determine the most accurate thresholds.</div></div><div><h3>Results</h3><div>The identified Vietnam-specific anthropometric thresholds for sarcopenia were: BMI ≤22.6 kg/m<sup>2</sup> for men and ≤21.2 kg/m<sup>2</sup> for women; CC ≤ 34.5 cm and ≤32.0 cm; AC ≤26.0 cm and ≤24.0 cm; WC ≤ 85.0 cm and ≤78.0 cm, respectively. These localized thresholds improved diagnostic accuracy, with BMI showing the strongest performance. CC and AC were less reliable among women, while WC offered high specificity but lower sensitivity.</div></div><div><h3>Conclusion</h3><div>Our results endorse Vietnam-specific anthropometric cutoffs, particularly BMI, as a practical, cost-effective sarcopenia screening tool for under-resourced primary care. Integrating these thresholds into national guidelines can accelerate universal health coverage and sustainable aging by enabling early detection and community-based interventions to avert functional decline in Vietnam's aging population.</div></div>","PeriodicalId":33615,"journal":{"name":"Global Transitions","volume":"8 1","pages":"Pages 120-128"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145736579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
