This study examines a seven-week informal familycentric rocketry pilot program designed for Latina girls in grades 5 and 6 and their parents. Grounded in Community Cultural Wealth and Culturally Sustaining Pedagogy, the program integrated Family Problem-Based Learning to position families as co-educators in science learning. Through activities such as designing NASA-style mission patches, constructing egg-drop devices, and launching rockets, the program sought to center family knowledge, bilingual practices, and cultural values within physical science experiences. Data reported here were collected through mid- and post-program surveys with both parents and daughters. Responses indicate strong engagement from families, with parents reporting increased high confidence in supporting their daughters’ science learning and daughters expressing enjoyment and strong interest in science learning. Both groups valued the use of English and Spanish and the program’s emphasis on collaborative, family-centered participation. Responses highlight the potential of culturally sustaining, familycentric approaches to address the underrepresentation of Latina women in Science, Technology, Engineering, and Math (STEM) by fostering a sense of belonging. This study contributes to informal science education by demonstrating how families can be centered in a program focused on physical science. School-based outreach of this kind may also strengthen families and parent–child relationships. Full article

Multimodal perception for student-state monitoring is difficult to deploy in rural classrooms because sensors are noisy and computing resources are highly constrained. This work targets these challenges by enabling noise-resilient, multimodal, real-time student-state recognition on low-cost edge devices. We propose LightEdu-Net, a sensor-noise-adaptive Transformer-based multimodal network that integrates visual, physiological, and environmental signals in a unified lightweight architecture. The model incorporates three key components: a sensor noise adaptive module (SNAM) to suppress degraded sensor inputs, a cross-modal attention fusion module (CMAF) to capture complementary temporal dependencies across modalities, and an edge-aware knowledge distillation module (EAKD) to transfer knowledge from high-capacity teachers to an embedded-friendly student network. We construct a multimodal behavioral dataset from several rural schools and formulate student-state recognition as a multimodal classification task with explicit evaluation of noise robustness and edge deployability. Experiments show that LightEdu-Net achieves 92.4% accuracy with an F1-score of 91.4%, outperforming representative lightweight CNN and Transformer baselines. Under a noise level of 0.3, accuracy drops by only 1.1%, indicating strong robustness to sensor degradation. Deployment experiments further show that the model operates in real time on Jetson Nano with a latency of 42.8 ms (23.4 FPS) and maintains stable high accuracy on Raspberry Pi 4B and Intel NUC platforms. Beyond technical performance, the proposed system provides a low-cost and quantifiable mechanism for capturing fine-grained learning process indicators, offering new data support for educational economics studies on instructional efficiency and resource allocation in underdeveloped regions.

Intermittent water supply is common in Palestine, prompting schools to rely on on-site water storage systems, including underground and roof tanks. Prolonged and uncontrolled water storage leads to quality degradation, especially with free residual chlorine (FRC) depletion. Hence, this poses health risks to students and staff. This pilot (field) study evaluated the effectiveness of booster chlorination under the current storage conditions to optimize and improve the existing chlorination process. Four schools were selected based on the type of water storage systems (two with underground tanks, two with roof tanks) and building age. Booster chlorination was applied at two chlorine doses (0.5 mg/L and 1 mg/L). FRC was monitored until levels dropped below 0.05 mg/L. Results show that the currently applied chlorine dose (0.5 mg/L) is insufficient to reach the minimum national FRC standard (0.2 mg/L) after 30 min. In contrast, a 1 mg/L chlorine dose is more effective in maintaining the minimum FRC concentration limit for a longer time. In addition, manual mixing is ineffective in large underground tanks, while it is effective in roof tanks. This study urges the need to revise the national chlorination guidelines and to adjust chlorination practices to ensure safe drinking water in schools. Full article

Objective: We assess the prevalence of myopia and its associated factors among schoolchildren in Madrid, Spain, where school-based data using cycloplegic refraction are currently scarce. Methods: A cross-sectional study was conducted in 39 randomly selected schools in Madrid, targeting children in the second (6–7 years) and sixth grades (11–12 years). Parents completed questionnaires detailing family ocular history, the child’s lifestyle, and screen time. Socio-economic status was inferred from the Human Development Index of school districts. Children were examined using a two-stage approach: initial screening with visual acuity testing and Plusoptix photorefraction (myopia screening cut-off ≤ 0.00 D spherical equivalent), followed by confirmatory cycloplegic autorefraction (three drops of cyclopentolate 1% administered at 10 min intervals), with myopia defined as spherical equivalent ≤ −0.50 D. Statistical analyses included chi-square tests and logistic regression models to evaluate associated factors. Results: Of 3680 children invited, 2489 (67.6%) were examined. Myopia prevalence was 6.5% in second grade and 18.7% in sixth grade. Family history of myopia was a significant risk factor (OR 2.04; 95% CI: 1.53–2.70; p < 0.001 for both parents). Outdoor activity during weekends was associated with lower myopia prevalence (OR 0.50; 95% CI: 0.37–0.66; p < 0.01 for 2–6 h). Screen time was not a significant factor in multivariate analysis. Conclusions: This large school-based study using cycloplegic refraction provides more accurate prevalence data for Spanish schoolchildren. It confirms family history as a major risk factor and highlights the association of outdoor activities with lower prevalence of myopia. These results underline the need for preventive measures and suggest areas for future interventional research. Full article

Demand-Responsive Transport (DRT) services ensure the implementation of more sustainable transport solutions and focuses on the creation of more flexible and personalised public transport systems. They help to reduce the use of cars, improve service efficiency, and reduce the environmental impact. The attractiveness of DRTs depends on the type of activities served (e.g., schools, hospitals, modal interchange hubs). The attractiveness of a specific stop depends not only on its location but also on proximity to essential services (such as schools). The aim of this study is to identify which categories of activities most influence users’ choice of stops. A conditional logit model is developed to analyse drop-off stop selection, based on the location and configuration of key stops and major attraction points in the monitored case study in Ragusa, Sicily (southern Italy). Accessibility to different attraction points from stops is considered as the main independent variable. The results show that proximity to sports facilities and schools strongly influence users’ choice of stops, along with nearby modal interchange stations and shopping-related activities. Conversely, stops near health centres tended to be less attractive in the study area. Furthermore, sports facilities exert the strongest attraction, while travel patterns to health services deviate from existing literature, likely reflecting the limited availability of complementary transport options.

Background: The introduction of prophylactic HPV vaccination has transformed cervical cancer prevention worldwide, yet many low- and middle-income countries face persistent challenges in implementation, coverage gaps, and vaccine hesitancy. This article presents a narrative review of global and Brazilian HPV vaccination programs, highlighting achievements, pitfalls, and lessons for future strategies. Methods: We reviewed peer-reviewed literature and official reports from WHO, PAHO, CDC, Brazilian institutions, and others, focusing on programmatic performance, coverage trends, and vaccine acceptance. Results: In high-income settings such as Australia and the United Kingdom, school-based vaccination programs have driven sharp declines in HPV prevalence, genital warts, and precancerous lesions, in some cases approaching elimination thresholds. The United States has made progress but continues to struggle with disparities in uptake linked to socioeconomic and cultural factors. In India and several African nations, recent evidence supports single-dose regimens as a cost-effective and logistically feasible strategy. In Brazil, HPV vaccination was introduced in 2014 via the National Immunization Program (PNI), initially targeting girls aged 9–13 years through school campaigns. First-dose coverage exceeded 80% in the first year but subsequently declined, with full-schedule completion rates dropping below 60%. Contributing factors include misinformation, weakening of school-based delivery, and pandemic-related disruptions. Brazil later expanded eligibility to boys and immunocompromised populations and, more recently, extended catch-up vaccination to older adolescents. Conclusions: HPV vaccination has the potential to substantially reduce cervical cancer incidence globally. However, sustained impact depends not only on infrastructure and universal access but also on consistent school-based delivery, adaptive policies such as single-dose regimens, and robust communication strategies to counter misinformation. Brazil’s experience offers both inspiration and caution, providing lessons for countries striving to meet the WHO 90-70-90 targets. Full article

Background/Objectives: The benefits of nature-based interventions to support well-being and mental health are increasingly well-documented in the literature; however, study of an occupational therapy gardening program for adolescents with exposure to adverse childhood experiences (ACEs) is limited. Methods: This study evaluates the feasibility of a novel school gardening program for youth with a history of ACEs including the following: (1) recruitment; (2) data collection procedures and outcome measures; (3) acceptability and suitability of the intervention; and (4) evaluation of the response to a gardening intervention as measured by a visual analog scale of emotional state, a heartbeat counting task designed to capture changes in interoceptive awareness, and qualitative data from the teacher and researchers. This feasibility study was designed as an 8- to 10-week program (10 sessions minimum) to accommodate the school’s academic curriculum and support the participants’ academic progression. Three adolescents were recruited, ages 12–17, two of whom completed a shorter version of the program and one who dropped out. Results: Results indicated the gardening intervention recruitment and data collection procedures were feasible. Intervention was acceptable to participants. Outcome measures that produce both quantitative and qualitative changes are needed. Interoceptive measures show promise but require further refinement. Response to intervention seemed to be influenced by the participant’s psychosocial history but suggests possible changes in prosocial behavior. External factors such as absenteeism influenced aspects of participation, including frequency and duration of intervention. Conclusions: These findings suggest gardening interventions in occupational therapy are feasible and suitable for adolescents with a history of adversity. Potential exists for enhanced social connectedness, which supports mental health and well-being. Suggestions are offered for implementation and outcome measurements appropriate for this population.

Retention of foundational knowledge is critical in dental education, yet the implications of Ebbinghaus forgetting curve are often overlooked. This study examined how well dental students retained core periodontal concepts and how confident in their knowledge evolved over the dental school years. A standardized 20-question multiple-choice exam was administered to 120 students at six points: before and after each of three progressive periodontal courses. Students also rated their confidence for each answer. Data from 113 students were analyzed. During the first-year course, mean scores increased significantly from 42–46% to 76–81%. After a four-month gap, second-year pre-course scores dropped to 66–70% and then rebounded to 84–89% post-course. In the third year, despite a nine-month gap, pre-course scores remained relatively high (78–81%) and rose slightly to 80–83% post-instruction. Performance and confidence improved significantly over time (p < 0.001), and a strong positive correlation was observed between them (r = 0.87, p < 0.001). These findings support the value of repeated reinforcement in promoting long-term knowledge retention and increasing student confidence. Full article

Background: This study examined treatment outcomes for cannabis use disorder (CUD) among adolescents (12–17 years old) in the United States. Methods: Data from the 2018–2021 Treatment Episode Data Set-Discharges (TEDS-D) included 40,054 adolescents diagnosed with CUD. Descriptive statistics, Chi-square tests, and multivariable logistic regression assessed treatment outcomes and factors associated with treatment completion. Results: Only 36.8% of adolescents completed treatment. The most common reasons for not completing treatment were dropping out (28.4%) and transferring to another facility/program (17.0%). Males and Black non-Hispanic adolescents had lower odds of completing treatment (OR = 0.79, 95%CI: 0.75–0.84), while Hispanic (OR = 1.13, 95%CI: 1.08–1.18), Asian (OR = 1.56, 95%CI: 1.3–1.86) and Native Hawaiian/Pacific Islander adolescents (OR = 2.31, 95%CI: 2.04–2.61) had higher odds of completion compared to their White counterparts. Independent living arrangements, homelessness, arrests in the past 30 days and younger age (<15 years old) decreased the likelihood of treatment completion. Adolescents with co-occurring mental health and substance use disorders also had lower completion rates (OR = 0.79, 95%CI: 0.77–0.86). Referral from schools/employers and treatment settings were associated with a higher success, particularly with stays of 4–6 months and 7–12 months. Conclusion: This study highlights the need for targeted CUD treatment programs that support at-risk adolescents, especially those experiencing homelessness or facing legal issues. High dropout and transition rates suggest a need for continuity of care and program integration between facilities. Strengthening coordination among public health officials, community organizations, and stakeholders is essential to developing culturally responsive treatment interventions that address social determinants of health, substance use, and mental health in this vulnerable population.

Background: Adolescent girls and young women (AGYW) who engage in alcohol and substance abuse face more significant health and social consequences compared to the general population. This study evaluated the prevalence and associated factors of alcohol abuse and substance use among AGYW in Namibia. Methods: We conducted a retrospective analysis of programmatic data from AGYW aged 10–24 who participated in the Determined, Resilient, Empowered AIDS-free, Mentored, and Safe (DREAMS) component of the Reducing HIV Vulnerability: Integrated Child and Youth Health (REACH) Project HOPE Namibia from March to December 2024. Data analysis was conducted employing chi-squared tests alongside binomial and multinomial logistic regression. Results: Among the 19,662 participants included in this analysis, 2068 (10.5%) abused alcohol and/or substances in the previous six months. Participants who were HIV-negative or did not know their status (AOR = 1.57, 95% CI (1.15–2.14), and AOR = 1.50, 95% CI (109–2.07), respectively), from outside Windhoek, those who had failed or repeated school in the previous year (COR = 1.77, 95% CI (1.54–2.05)), those not disabled (AOR = 1.27, 95% CI (1.06–1.52)), those who had dropped out of school or had completed their studies, and those with no adult emotional support (AOR = 1.25, 95% CI (1.11–1.40)), were more likely to have abused alcohol and/or substances recently. In contrast, participants who were not depressed were less likely to have recently abused alcohol and substances. Conclusions: The prioritization of strategies to identify AGYW experiencing depression and to provide them with treatment is essential. Moreover, it is important to encourage parents and guardians to provide emotional support to AGYW, as it prevents them from abusing alcohol and substances. Full article

Background and Objectives: The COVID-19 pandemic affected children’s lifestyle, due to strict lockdown restrictions. This study evaluated Romanian children’s lifestyle prior to and during the pandemic and their associated factors. Materials and Methods: A longitudinal study was performed in 7 urban schools from Romania. Data were gathered at baseline (T1), from October to November 2019, and follow-up (T2), from December 2020 to February 2021. Results: A total of 880 children were enrolled at baseline, 484 at T2, and 350 in both evaluations. Initially, 66.3% did not perform at least one hour of physical activity per day, two thirds did not sleep at least 9 h per night during the week, and more than one third used the internet more than 2 h daily. Investigating changes before and during COVID-19 among students participating at both evaluations, a statistically significant drop in physical activity and sleep time during the week was recorded, while weekend sleep and internet use increased. Several gender- and age-related differences were noted. Physical activity and sleep patterns as well as internet use behavior at T1 predicted the same behavior at T2. Reduced sleep during the week and internet overuse were positively associated at both waves as well as longitudinally. Conclusions: These findings highlight calls for combined strategies that include parents, schools, and community, aiming to enhance a healthier lifestyle among children. Full article

In this study, a Long Short-Term Memory (LSTM) model with extra variables such as weather conditions and school days was developed within a multi-scale framework in order to forecast passenger flow in both bus and rail systems, covering both regional and route-level analyses. In addition, the performance of the LSTM model was compared against three separate deep learning models. Among these, the Nonlinear Autoregressive Network with Exogenous Inputs (NARX) time series model produced the lowest error values, achieving a high level of accuracy. While no considerable changes were observed in regional rail passenger flow as a result of the inclusion of weather-related variables, a 2.2% drop in the RMSE value was achieved in bus passenger flow at the regional level; however, this improvement remains relatively modest. In contrast, at the route level, RMSE values declined by 2.4% for rail and 3.69% for bus routes. These findings reveal that the inclusion of weather-related variables significantly improves the prediction of bus passenger flow, underlining the benefits of integrating such data into forecasting models. Furthermore, the findings of this study analytically support transportation planners in making more informed, data-driven decisions regarding scheduling and capacity management. Full article

This study investigates the dropout risk among first- and second-year high school students in the peripheral areas of Southern Italy, where the dropout rates are extremely high. It focuses on individual and relational factors associated with dropout, analyzing data from 645 students (M_age = 14.64) who completed a self-report questionnaire. The examined variables include self-efficacy, amotivation, future orientation, peer relationships, and students’ trust in teachers. Hierarchical regressions assessed the influence of grade levels on these dimensions. Our findings show a positive developmental trend in second-year students, including higher self-efficacy, better peer relationships, and reduced intentions to drop out. However, trust in teachers declines during this transition. Moreover, relationships with teachers show no significant improvement across grades. Therefore, this study underscores the importance of fostering trust between students and teachers as a protective factor against dropout. It also reveals the need for interventions targeting both students and the educational environment to improve teacher–student relationships and support students’ educational aspirations. By addressing these relational aspects, stakeholders can better mitigate dropout risks and promote school engagement during critical transitions in adolescence. Full article

Educational achievement plays a significant role in the labour market, benefiting individuals and society. Graduating from high school is a key step towards better employment opportunities and a prerequisite for higher education attainment. In 2023, only 22.5% of the Romanian population graduated tertiary education, while 16.6% left education or training early. The Romanian public high school network comprises 1558 units, mostly located in urban areas. The high school enrolment rate is 83.5% in urban areas, and it drops to less than 60% in rural areas, with the country registering the highest out-of-school rate in the EU for the 15-year-old population. Spatial accessibility may influence enrolment in high schools, particularly for students living in rural or remote areas, who often face financial challenges fuelled by long distances and limited transportation options. Hence, travel distance may represent a potential barrier to completing the educational process or may determine inequalities in educational opportunities and outcomes. This paper aims to assess the spatial accessibility of the public high school network in Romania by using distance data provided by the Open Street Map API (Application Programming Interface). We examine variations in spatial accessibility based on the distribution of high school units and road network characteristics considering three variables: travel distance to the nearest high school, the average distance to three different categories of high schools, and the number of high schools located within a 20 km buffer zone. The results highlight a significant urban–rural divide in the availability of public high school facilities, with 84.1% (n = 1311) located in urban areas while 49.1% of the high school-aged population lives in rural areas. Many rural communities lack adequate educational facilities, often having limited options for high school education. The findings also show that 32% of the high school-aged population has to travel more than 10 km to the nearest high school, and 7% has no high school options within a 20 km buffer zone. This study provides insights into the educational landscape in Romania, pointing out areas with limited access to high schools, which contributes to further inequalities in educational attainment. The findings may serve as a basis for developing policies and practices to bridge the urban–rural divide in educational opportunities and foster a more equitable and inclusive education system.

College enrollment has long been recognized as a critical pathway to better employment prospects and improved economic outcomes. However, the overall enrollment rates have declined in recent years, and students with a lower socioeconomic status (SES) or those from disadvantaged backgrounds remain significantly underrepresented in higher education. To investigate the factors influencing college enrollment among low-SES high school students, this study analyzed data from the High School Longitudinal Study of 2009 (HSLS:09) using five widely used machine learning algorithms. The sample included 5223 ninth-grade students from lower socioeconomic backgrounds (51% female; M_age = 14.59) whose biological parents or stepparents completed a parental questionnaire. The results showed that, among all five classifiers, the random forest algorithm achieved the highest classification accuracy at 67.73%. Additionally, the top three predictors of enrollment in 2-year or 4-year colleges were students’ overall high school GPA, parental educational expectations, and the number of close friends planning to attend a 4-year college. Conversely, the most important predictors of non-enrollment were high school GPA, parental educational expectations, and the number of close friends who had dropped out of high school. These findings advance our understanding of the factors shaping college enrollment for low-SES students and highlight two important factors for intervention: improving students’ academic performance and fostering future-oriented goals among their peers and parents.
