Background Active school commuting is a relevant opportunity to increase daily physical activity among adolescents. However, participation rates remain low, particularly in middle-income countries, where structural, environmental, and social factors may interact in complex ways. Understanding these multilevel associations is essential to inform effective transport and public health strategies. Objectives To examine the associations between distance to school, perceived built environment, type of school, and active school commuting among adolescents in Chile. Methods A cross-sectional study was conducted with 200 secondary school students (mean age: 17.0 ± 0.35 years) from public, subsidized, and private schools in Talca, Chile. Active commuting was assessed via self-report and categorized as active (walking or cycling) or motorized. Distance to school was classified as <3 km or ≥3 km. Perceived built environment was measured using the ALPHA questionnaire. A binary logistic regression model was used to examine associations, adjusting for school type, sex, home-to-school distance, and the perceived built-environment dimensions retained in the final model: connectivity, home environment, and school environment. Results are presented as odds ratios (OR) with 95% confidence intervals (CI). Results The prevalence of active commuting was low (10.9% to school; 23.8% from school). Distance to school showed the strongest association with active commuting (OR = 0.44; 95% CI: 0.28–0.69; p < .001), with greater distances associated with lower likelihood of active travel. Perceived connectivity was also inversely associated with active commuting (OR = 0.71; 95% CI: 0.54–0.92; p = .011). No significant associations were found for type of school, sex, or other environmental variables. Conclusions Active school commuting among adolescents is primarily associated with structural factors, particularly distance to school, rather than individual or perceived environmental characteristics. These findings highlight the need to integrate urban planning, educational policies, and transport strategies to promote active commuting, especially in middle-income contexts characterized by spatial inequalities.
Nature-based solutions (NbS) are increasingly promoted for coastal adaptation; however, ecological restoration gains and reductions in wave energy do not necessarily demonstrate sustained control of coastal erosion. This systematic review synthesizes peer-reviewed literature published between 2010 and 2025 to examine how coastal typology, hydrodynamic forcing, sediment balance, monitoring design, and governance influence NbS performance. Searches in Scopus and the Web of Science Core Collection generated 3138 query-level retrievals; after deduplication, screening, and full-text eligibility assessment, 126 studies were included. The evidence synthesis informed the development of a typology-based eligibility framework that identifies when stand-alone NbS, hybrid measures, enabling actions, sediment management, managed retreat, or technical non-eligibility may represent defensible management outcomes. The framework distinguishes process indicators, such as wave attenuation and sediment retention, from geomorphological and risk-reduction outcomes, including shoreline change, beach–dune volume, overtopping frequency, and sediment-budget trajectories. It further integrates problem definition, baseline characterization, threshold-based design, performance validation, adaptive monitoring, and governance within an operational decision pathway. When considered in the Colombian Caribbean context, the framework highlights the relevance of regional sediment deficits, strong alongshore transport, ecosystem degradation, urban encroachment, and fragmented institutional responsibilities for intervention eligibility and long-term performance. Relative to broader NbS guidance, the proposed approach provides an erosion-specific integration of typology screening, mechanism–outcome differentiation, performance verification, and non-eligibility decisions. Because the framework represents a structured synthesis rather than a validated predictive model, its thresholds and decision rules require further testing against documented intervention outcomes and comparative coastal case studies.
The giant kelp Macrocystis pyrifera is a foundational species in marine coastal ecosystems, yet its microscopic life stages are particularly vulnerable to warming and pollution. We examined its seasonal phenology over an annual cycle initiated under the 2023—2024 El Niño warming at Horcón (central Chile), a coastal site strongly influenced by long-term industrial activity. Sori were collected in austral spring and summer to winter, and in vitro cultures were used to quantify settled spores, germination, gametophyte and sporophyte development, sex ratio, fecundity, and reproductive success. Sea surface temperature (SST) data showed strong seasonal contrasts, with warm anomalies in summer-autumn linked to the coastal El Niño, followed by markedly cooler conditions in winter. Winter cultures, after El Niño waned, reached 220,500 spores cm⁻2, nearly ten times higher than in spring and autumn and twenty times higher than in summer. Germination peaked in winter (96—100
PurposeThis study aims to investigate how social media recommendations influence investor attention and retail investor activity in stock investing.Design/methodology/approachUsing data from the Organisation for Economic Co-operation and Development (OECD)'s 2023 Adult Financial Literacy Survey across a sample of countries, the analysis employs a logistic regression model. To address potential endogeneity, both instrumental variable and propensity score matching techniques are applied.FindingsInvestor attention to social media influencers shows a positive and significant effect on stock investment. After adjusting for endogeneity, the main results remain robust. However, the moderating role of digital financial literacy is not consistent across all countries in the sample.Research limitations/implicationsThe influencer recommendation question was newly introduced in this survey, limiting longitudinal comparisons. Additionally, the results are based on self-reported data from four countries.Originality/valueThis research contributes to the emerging field of digital behavioral finance and offers insights for the design of financial inclusion and education policies in increasingly digital environments.
Psychological skills of athletes determine their sporting performance. However, the development of these skills requires a learning process, influenced by the athlete's environment. The aim of this study was to investigate the relationships between an empowering and disempowering climate, motivational orientation (ego vs. task), and the sport psychological profile in a sample of football players. A total of 328 young players aged between 14 and 18 years (M= 15.85; SD= 1.44) participated in this research. Data was collected using the Psychological Inventory of Sport Execution, the Empowering and Disempowering Climate Questionnaire, and the Task and Ego Orientation in Sport Questionnaire. The results obtained in this study through structural equation analysis showed significant and positive relationships between empowering climate and task orientation, as well as between disempowering climate and ego orientation. Similarly, positive and significant relationships were found between task orientation and the athlete's psychological skills. Moreover, there were positive and indirect relationships between an empowering climate and the athlete's psychological variables. These results suggest the importance of promoting appropriate motivational climates, as well as directing the athlete's motivation towards learning goals to foster the development of psychological skills on young players.
