This narrative case-based review describes the environmental and public health impacts in Chañaral, a town in northern Chile affected by the accumulation of copper mining tailings for the past 80 years. The review included 34 scientific articles published between 1978 and 2025. The keywords used were “mining tailings” and “Chañaral”, without year limits, and covering disciplines such as ecology, public health, environmental history, and territorial studies. The scientific evidence demonstrates the negative impacts on the ecosystem and the human population exposed to toxic metals and arsenic. Geomorphological and biogeochemical alterations have been found on the Chañaral coast, affecting marine biodiversity and water quality. In addition, epidemiological studies indicate exposure to toxic metals measured in street dust and urine, raising concerns on respiratory health in children and metabolic conditions in adults. According to the social sciences, the lack of environmental monitoring and human exposure data contributes to the high health risk perception in the population, posing the need to strengthen environmental monitoring, raise awareness on the risks of exposure to toxic metals, and promote mitigation and restoration strategies. These measures will contribute to sustainable conditions for the Chañaral community through the improvement of comprehensive public policies. Full article

Farm-to-school (F2S) partnerships connect schools with local producers to enhance student access to healthy, local foods and support regional food systems. Despite widespread implementation, few studies have examined the system-level structures that facilitate effective and sustainable F2S efforts across diverse community contexts. This study utilized a mixed-methods system mapping approach to analyze four F2S systems on California’s Central Coast. Data sources included public data sources, in-person site observations, and local expert resources. The researchers hypothesized that successful F2S systems would share core features that support implementation and long-term sustainability, including aligned values among stakeholders, the presence of identified champions, and multi-directional pathways for food procurement and communication. They constructed system maps and compared them in order to identify both common structural features and context-specific adaptations. Findings support the hypothesis and highlight the critical role of community-based organizations and distributors and/or aggregators in brokering relationships, coordinating resources, and reducing administrative burdens. Institutionalization through wellness policy integration and district-level support further distinguished higher-functioning systems. Identified barriers included inequities in procurement infrastructure, limited funder engagement, and uneven access to local food sources. System mapping offers a valuable tool to understand, strengthen, and scale equitable F2S implementation. Full article

To achieve the sustainable development of nature reserves, the public welfare associated with these areas has been assessed based on ecological supply and social demand. The Public Welfare Index comprehensively incorporates ecological factors, such as landforms, resource endowment, and ecological quality, as well as socio-economic factors, including travel costs, economic base, and population distribution. This index reflects both the ecological supply capacity of nature reserves and the equity with which they provide welfare to different groups. The findings indicate that the Public Welfare Index is an effective measure of the rationality of welfare distribution. Currently, the public welfare of nature reserves in China exhibits a spatial pattern of high welfare in the west and low welfare in the east. This issue of welfare inequality in nature reserves is highly pronounced. The primary objective of this research is to identify the characteristics of welfare distribution and to offer novel perspectives and strategies for optimizing the spatial layout of nature reserves and informing policy decisions.

Objectives: To theorize the work-related dimension involved in the process of reconciling work and personal roles among nurses working in Intensive Care Units. Methods: Constructivist grounded theory was employed to conceptualize the phenomenon of interest from the perspectives of nurses, their families, and administrative staff. Data were derived from 202 h of non-participant observation in two high-complexity hospitals in Chile (one public and one private), 57 institutional documents, and 51 in-depth interviews. Data analysis followed the constant comparative method and multilevel coding. To ensure methodological rigor, the study adhered to the 13 criteria for constructivist grounded theory research proposed by Charmaz and Thornberg and was approved by a scientific ethics committee. Results: Work-related roles are defined as the set of behaviors associated with the professional context, which are shaped by nine sources of interaction: (1) Job content; (2) Workload and pace; (3) Work schedule; (4) Control; (5) Environment and equipment; (6) Organizational culture; (7) Interpersonal relationships; (8) Function within the organization; and (9) Career development. Conclusions: The study presents the theorization process of the work-related dimension involved in the reconciliation of work and personal roles among nurses in Intensive Care Units. Work-related roles are essential to understanding this reconciliation process. The findings provide evidence for the existence of nine sources of interaction, which are influenced by institutional strategic planning and, in turn, by national and international public policies.

Flexibility is increasingly recognized as a key competence in addressing current challenges and transitions. It is a multidimensional construct, discussed across various disciplines, encompassing cognitive, behavioral, and emotional dimensions. The European LifeComp framework offers one of the most recent and comprehensive definitions of this competence, emphasizing its role in enabling individuals to adapt to uncertainty, manage complexity, and foster transformative learning. This study investigates the assessment tools available to evaluate flexibility competence, focusing on their alignment with the LifeComp framework. A systematic literature review was conducted using the Scopus and WoS databases, based on inclusion criteria for language, publication type, disciplinary area, research topic, and target population, identifying 22 eligible articles. Following a quality assessment of the articles, a critical analysis revealed the presence of 22 tools and scales, including the actively open-minded thinking (AOT) scale, the resistance to change (RTC) scale, and the flexible thinking in learning (FTL) questionnaire. The findings show overlaps among flexibility and related constructs, such as learning agility and intellectual humility. However, most tools are context-specific and fail to address the multidimensional nature of flexibility competence. Future research should prioritize the development of comprehensive instruments to support educational initiatives, policy development, and professional training. Full article

In the current context where China is continuously emphasizing the construction and supply of indemnificatory housing, and actively promoting the construction of “Better Housing” for such housing, the development experiences of Japan and South Korea in the field of public housing reveal that the construction and supply of public housing cannot be separated from the interaction and coordinated development of the policy system, spatial composition, and cultural factors. Based on this, this study takes the public rental housing in China, Japan, and South Korea as the research objects, through comparative analysis of their policy systems, cultural backgrounds, and spatial composition characteristics of unit plans, to explore the implications for the development of China’s indemnificatory housing, and provides theoretical basis and practical references for optimizing the supply system and space design of China’s indemnificatory housing. The study selects typical cases of public rental housing from the three countries, and conducts comparisons from dimensions such as unit plane shape, L.D.K. layout, bedroom configuration, transitional space, balcony design, and bathroom composition. Findings indicate that Japan’s UR rental housing focuses on refined and diversified design, South Korea’s public housing emphasizes spatial flexibility, while China’s indemnificatory housing, while pursuing standardized construction, faces challenges of area limitations and insufficient functional adaptability. Based on the experiences of the three countries, this study proposes a tripartite guidance suggestion of “Policy–Space–Culture” to advance the realization of “Better Housing” objectives and ensure that China’s indemnificatory housing meets both international advanced experience and local social and cultural specific needs: (1) policy systems—strengthening legalization and long-term sustainability in governance; (2) spatial composition—incorporating flexible layouts and human-centric detailing; (3) cultural adaptability—balancing traditional living habits with contemporary needs.

The metropolitan agglomeration in and around Bucharest, Romania’s capital and largest city, has experienced significant growth in recent decades, both economically and demographically. With over two million residents in its metropolitan area, Bucharest faces urban mobility challenges characterized by congested roads, overcrowded public transport routes, limited parking, and air pollution. This study evaluates the potential of AI-driven adaptive traffic signal control to address these challenges using an agent-based simulation approach. The authors focus on Bucharest’s north-western part, a critical congestion area. A detailed road network was derived from OpenStreetMap and calibrated with empirical traffic data from TomTom Junction Analytics and Route Monitoring (corridor-level speeds and junction-level turn ratios). Using the MATSim framework, the authors implemented and compared fixed-time and adaptive signal control scenarios. The adaptive approach uses a decentralized, demand-responsive algorithm to minimize delays and queue spillback in real time. Simulation results indicate that adaptive signal control significantly improves network-wide average speeds, reduces congestion peaks, and flattens the number of en-route agents throughout the day, compared to fixed-time plans. While simplifications remain in the model, such as generalized signal timings and the exclusion of pedestrian movements, these findings suggest that deploying adaptive traffic management systems could deliver substantial operational benefits in Bucharest’s urban context. This work demonstrates a scalable methodology combining open geospatial data, commercial traffic analytics, and agent-based simulation to rigorously evaluate AI-based traffic management strategies, offering evidence-based guidance for urban mobility planning and policy decisions.

Monuments and public sculptures embody collective memory, values, and identity. This study analyses the representation of women in public sculptures in Ibarra, Ecuador, and evaluates citizens’ recognition of the historical figures depicted. A mixed-method, cross-sectional design was employed. An urban inventory was conducted (N = 124 sculptures), and questionnaires were administered in situ to 1200 adult residents using non-probability intercept sampling (100 surveys at each of the 12 female monuments). The results reveal a marked disparity: 55.6% of the sculptures represent men, compared with only 9.7% representing women. Recognition is minimal: 98.6% of respondents did not identify the person represented, and 95.1% reported no knowledge of her history. These findings suggest that the underrepresentation of women in public art reflects enduring structural and cultural gender inequalities. The limited presence of female monuments contributes to the erasure of women’s legacy from collective memory and perpetuates the perception of public space as historically male-dominated. Framed within the literature on gender and monuments as devices of social memory, the study advocates for inclusive commemorative policies and interpretive strategies. Limitations include the non-random sampling and single-city scope; future research should expand comparisons across cities and assess potential interventions. Full article

Objectives: Hepatitis E virus (HEV) infection is associated with severe hepatitis and high mortality rates, yet vaccination coverage remains suboptimal. Investigating public preferences for HEV vaccination is critical for developing targeted prevention strategies. This study employed a discrete choice experiment (DCE) to quantify attribute preferences and willingness-to-pay (WTP) for HEV vaccination among Chinese residents (in Shaanxi Province, for example), aiming to inform evidence-based immunization policy optimization. Methods: A cross-sectional survey recruited 3300 participants using stratified random sampling. The vaccine attributes—protective efficacy, duration of protection, and out-of-pocket cost—were identified using a systematic literature review and expert consultation. A comparative analysis of preference characteristics was conducted using conditional logit (Model 1) and mixed logit (Model 2) regression models. Population heterogeneity in vaccination preferences was further analyzed using the conditional logit framework, with marginal WTP estimated using parameter coefficients. Results: Among 3199 valid responses, duration of protection (Model 2: 10-years; β = 0.456, p < 0.001) and out-of-pocket cost (Model 2: 2000–3000 CNY; β = −0.179, p < 0.001) significantly influenced vaccination decisions. Preference heterogeneity was observed: women of childbearing age prioritized longer protection (10 years; β = 0.677, p < 0.001) and were sensitive to the cost of 1000–2000 CNY (β = 0.169, p = 0.011), while urban residents valued extended protection more than rural counterparts. Conclusions: Protection duration emerged as the primary determinant of HEV vaccination preference. Policy recommendations include implementing tiered pricing strategies and targeted health education campaigns emphasizing long-term protection benefits to enhance vaccine uptake and affordability.

This paper proposes a mathematical model based on modified geometric progressions for supplementary retirement planning. Unlike traditional annuity models that assume fixed contributions and withdrawals, the proposed method incorporates inflation-indexed contributions and withdrawals. This allows for accurate simulations aligned with real-world financial behavior. The model has practical applicability in pension fund policy, personal financial planning tools, and governmental simulations. A case study is developed, demonstrating that with a 3% annual geometric annuity and a 0.5% monthly interest rate, an initial deposit of R$ 767.67 over 25 years results in a monthly retirement income of R$ 3049.19 for 30 years, with preserved purchasing power. The model offers a practical and realistic tool for individual retirement planning and paves the way for future applications in both public and private pension systems. Full article

In Pakistan and most other developing nations, the residential building sector is one of the highest energy-consuming domains. The residential sector has the highest share of 50% of final electricity use of the country. Though Energy Conservation Building Codes (ECBC-2023) provide structured energy guidelines, no work has been performed to quantify the actual energy-saving potential of code-compliant retrofits in residential buildings. This study investigates the performance of ECBC-compliant retrofitting strategies for residential buildings under Pakistan’s diverse climatic conditions. The Passive House Planning Package (PHPP), a validated simulation tool, was used to assess energy performance improvements through building envelope interventions such as thermal insulation, solar shading, window glazing, and optimal orientation. Field data were collected from three representative cities, Multan (hot desert), Taxila (humid subtropical), and Quetta (cold semi-arid), to simulate both conventional and energy-efficient building scenarios. The results showed substantial seasonal energy savings in all three climates. During the heating period, energy savings were 48%, 50%, and 60% for Taxila, Multan, and Quetta, respectively. Similarly, energy savings during the cooling season were 44%, 33%, and 16%. Life cycle economic analysis revealed that these retrofits yielded Net Present Values (NPVs) of USD 752 (Taxila), USD 1226 (Multan), and USD 1670 (Quetta) over a 30-year period, with discounted payback periods ranging from 6 to 10 years. Furthermore, a life cycle assessment demonstrated that retrofitted buildings yielded up to 26% reduction in overall carbon emissions, combining both embodied and operational sources. The findings highlight that ECBC-2023 is not only a technically viable solution for energy savings but also financially attractive in residential retrofitting. By incorporating localized climate responsiveness into ECBC-compliant building design, the study provides a practical roadmap for achieving Pakistan’s energy efficiency goals. Additionally, the outcomes serve as a basis for informing policy initiatives, supporting building code adaptation, and raising public awareness of sustainable housing practices. Full article

Recent years have witnessed a concerning rise in early-onset eating disorders (EDs), prompting a re-evaluation of their etiology, diagnosis, and treatment within pediatric populations. This perspective article synthesizes emerging evidence on the multifactorial origins of EDs in children, emphasizing a biopsychosocial framework that integrates genetic, epigenetic, psychological, and environmental factors. While early manifestations often diverge from adolescent or adult profiles—marked by somatic complaints, selective eating, and ritualistic behaviors—the disorders significantly interfere with developmental milestones. The COVID-19 pandemic has further exacerbated vulnerabilities, acting as a catalyst for disordered eating behaviors through increased familial stress, isolation, and disrupted routines. Central to this framework is the role of parental psychopathology and parent–child feeding interactions, which profoundly shape children’s emotional regulation and attachment patterns. Recent studies also underscore genetic susceptibilities—especially variants in the DRD4 and DAT1 genes—and epigenetic modifications that may mediate the transmission of risk across generations. The article reviews evidence from observational and genomic studies, highlighting how altered gene expression linked to early environmental stress contributes to the heterogeneity of EDs. Finally, it evaluates prevention and intervention strategies, including family-based treatments, digital health tools, and school-based programs. These strategies are essential for timely detection, individualized care, and reducing long-term impairment. Overall, the paper advocates for a nuanced understanding of EDs in children—recognizing their complex origins and developmental implications—to inform clinical practice, public health policy, and future research in pediatric mental health.

At present, the decarbonization of the public transport sector plays a key role in international and regional policies. Among the various energy vectors being considered for future clean bus fleets, green hydrogen and electricity are gaining significant attention thanks to their minimal carbon footprint. However, a comprehensive Life Cycle Assessment (LCA) is essential to compare the most viable solutions for public mobility, accounting for variations in weather conditions, geographic locations, and time horizons. Therefore, the present work compares the life cycle environmental impact of different powertrain configurations for urban buses. In particular, a series hybrid architecture featuring two possible hydrogen-fueled Auxiliary Power Units (APUs) is considered: an H2-Internal Combustion Engine (ICE) and a Fuel Cell (FC). Furthermore, a Battery Electric Vehicle (BEV) is considered for the same application. The global warming potential of these powertrains is assessed in comparison to both conventional and hybrid diesel over a typical urban mission profile and in a wide range of external ambient conditions. Given that cabin and battery conditioning significantly influence energy consumption, their impact varies considerably between powertrain options. A sensitivity analysis of the BEV battery size is conducted, considering the effect of battery preconditioning strategies as well. Furthermore, to evaluate the potential of hydrogen and electricity in achieving cleaner public mobility throughout Europe, this study examines the effect of different grid carbon intensities on overall emissions, based also on a seasonal variability and future projections. Finally, the present study demonstrates the strong dependence of the carbon footprint of various technologies on both current and future scenarios, identifying a range of boundary conditions suitable for each analysed powertrain option.

Background/Objectives: To prevent nutritional depletion and impaired weight status in infants, targeted public health policies and prevention programs based on scientific evidence are needed. This study provides an overview of the dietary patterns and feeding behavior of infants in Croatia as part of the National Food Consumption Survey on Infants and Children. Methods: This cross-sectional study was conducted following the EU Menu methodology and included 322 healthy infants (54% boys; aged 3 months up to 12 months) from Croatia. Two-day dietary records were collected and analyzed using NutriCro 2.0 software. Results: The daily energy intake of infants was on average 886 ± 219 kcal, mainly from carbohydrates (47.0%), followed by fat (41.6%) and protein (9.9%). The main sources of energy and macronutrients were milk and dairy products, grains, grain products, potatoes and tubers and the fruit food group. One third of infants were breastfed, and more than 70% of infants were introduced to complementary foods. Parents started complementary feeding at the age of 5.37 ± 0.82 months, mostly with vegetables. Breastfeeding was associated with higher energy intake, especially in infants younger than 6 months, while formula feeding was associated with lower energy intake. The multivariate regression models showed age-related interactions that attenuated the patterns for energy and macronutrient intake. Conclusions: The study emphasizes that milk and dairy products are the main source of energy and macronutrients. The study highlights the important role of breastfeeding in promoting higher energy intake in early infancy and the decreasing effect of infant formula consumption with age. These results can be used as a basis for health policies, programs and strategies that address infant feeding habits in Croatia. Full article
