Background: There is an immense debate about the factors that could limit the adoption of agroforestry systems. However, one of the most important is the generation of scientific information that supports the viability and benefits of the proposed techniques. Statistical analysis: This work used the Latent Dirichlet Allocation (LDA) modeling method to identify and interpret scientific information on topics in relation to existing categories in a set of documents. It also used the HJ-Biplot method to determine the relationship between the analyzed topics, taking into consideration the years under study. Results: A review of the literature was conducted in this study and a total of 9794 abstracts of scientific articles published between 1993 and 2022 were obtained. The United States, India, Brazil, the United Kingdom, and Germany were the five countries that published the largest number of studies about agroforestry, particularly soil organic carbon, which was the most studied case. The five more frequently studied topics were: soil organic carbon, adoption of agroforestry practices, biodiversity, climatic change global policies, and carbon and climatic change. Conclusion: the LDA and HJ-Biplot statistical methods are useful tools for determining topicality in text analysis in agroforestry and related topics.

Previous studies have shown that the transition from the University environment to remote learning impacted student mental health. Our study aimed to investigate the effects of university environment on anxiety and depressive symptoms in health sciences students. Students at the Technical University of Manabí, Ecuador, with 6–10 in-person semesters, who shifted to remote learning and then returned to face-to-face learning were selected. Students responded to the General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). In addition, questions regarding social interaction, physical exercise, mood and sleep habits were also asked. This longitudinal study tracked 323 students during the return to in-person classes and term end. The results showed similar rates of anxiety (GAD-7, p = 0.011-p = 0.002) and depression (PHQ-9 p = 0.001-p = 0.032) among students at week 1 and week 15. Previous diagnosis of depression (OR, 0.171; CI 0.050–0.579, p < 0.005) was shown to correlate with depression levels in week 1, with no changes seen at follow-up. Anxiety levels were shown to be associated with a previous diagnosis of the disorder at week 1, but not at follow-up (OR 0.233; CI 0.085–0.643, p < 0.005). The return to in-person learning among university students maintained levels of anxiety and depressive symptoms, underscoring ongoing vulnerabilities to mental health disorders in this group.

Every cultural institution providing services to external users must be frequently evaluated to know user satisfaction and management optimally; multivariate methods are an alternative in constructing indexes due to the goodness of the techniques in interrelating a set of characteristicssimultaneously. To initiate the research, a bibliographic search was carried out using keywords such as "multivariate methods," "composite indicators," "public management," "quality service," and "user satisfaction." As a result, the most frequently found techniques are multiple linear and logistic regression, factorial, cluster analysis, canonical correlation, principal components and correspondence analysis, variable selection, and construction of composite indexes. It is concluded that multivariate methods are optimal methodologies for constructing composite indexes. However, a methodology based on multivariate techniques applied in cultural management measurements in a standard way still needs to be improved. Toda institución de carácter cultural en el que se presta servicio a usuarios externos debe ser evaluada frecuentemente, con el fin de conocer la satisfacción del usuario y la gestión de manera óptima; siendo los métodos multivariantes una alternativa en la construcción de índices por la bondad de las técnicas en interrelacionar un conjunto de características simultáneamente. Para iniciar la investigación se procedió a la búsqueda bibliográfica utilizándose palabras claves como “métodos multivariantes”, “indicadores compuestos”, “gestión pública”, “servicio de calidad” y “satisfacción de usuario”. Como resultado, las técnicas más encontradas son: regresión lineal múltiple y logística, factorial, análisis clúster, correlación canónica, componentes principales y análisis de correspondencias, la selección de variables y construcción de índices compuestos. Se concluye que los métodos multivariantes son metodologías óptimas para la construcción de índices compuestos, aunque falta una metodología basada en técnicas multivariantes que se aplique en mediciones de gestión cultural de manera estándar.

La ausencia de instrumentos integrales y métricamente validados para evaluar la calidad del servicio en museos limita la toma de decisiones estratégicas y la mejora de la gestión cultural, particularmente en contextos donde predominan mediciones fragmentadas y descriptivas. En este marco, la investigación tuvo como objetivo construir y validar un índice compuesto de calidad de servicio para los museos de la Corporación Ciudad Alfaro, mediante la aplicación de técnicas estadísticas multivariantes que permitieran modelar la estructura latente de la percepción de los visitantes. Se adoptó un diseño cuantitativo, no experimental y transversal, con aplicación de un cuestionario basado en el modelo SERVQUAL a 415 visitantes, utilizando análisis de correspondencias múltiples y análisis factorial para la reducción dimensional y estimación de ponderaciones empíricas. Los resultados evidenciaron una varianza explicada del 65,33 %, elevada consistencia interna y predominio de respuestas en niveles altos de satisfacción, identificándose como factores críticos la capacidad resolutiva del personal, la calidad de los objetos exhibidos, la complacencia del visitante y condiciones de infraestructura como suministro eléctrico y limpieza. La validación estructural confirmó la coherencia métrica del índice y su pertinencia como instrumento sintético para evaluar de manera integral la calidad del servicio museístico y orientar procesos de optimización institucional. Palabras clave: calidad de servicio, museos, índice compuesto, análisis multivariante, SERVQUAL, satisfacción del visitante.

Web accessibility ensures that all individuals, including people with disabilities, can interact effectively with digital portals. This study evaluates and classifies the levels of web accessibility of the official portal of the Decentralized Autonomous Government (GAD) of the canton of Portoviejo, Ecuador, using an unsupervised fuzzy clustering approach. Automated metrics aligned with the Web Content Accessibility Guidelines (WCAG 2.1, Level AA) were collected using the web accessibility test (TAW) tool. Subsequently, exploratory factor analysis (EFA) was applied to reduce the dimensionality of 21 initial criteria, retaining seven latent factors representative of web accessibility. Based on these factors, the fuzzy C‐means (FCM) algorithm was implemented to group the evaluated pages into accessibility levels. The results reveal the existence of clusters with overlapping boundaries, confirming that web accessibility constitutes a continuum rather than a binary condition. Finally, the study provides accessibility profiles and practical recommendations by the cluster, contributing to the progressive improvement of digital inclusion in the context of local public administration.

La presente revisión sistemática de literatura examina la efectividad de las tecnologías de Realidad Virtual (RV), Realidad Aumentada (RA) y Realidad Mixta (RM) en los procesos de enseñanza-aprendizaje. Siguiendo las directrices PRISMA 2020, se analizaron 25 estudios empíricos y de revisión publicados entre 2020 y 2025, obtenidos de bases de datos como Scopus, Web of Science, IEEE Xplore y ScienceDirect. Los resultados indican de manera consistente que las tecnologías inmersivas producen efectos positivos significativos sobre los resultados de aprendizaje, la motivación académica, el compromiso estudiantil y el desarrollo del pensamiento de orden superior. La RV muestra el mayor impacto en habilidades prácticas y procedimentales (g = 0.477), la RA mejora significativamente actitudes y rendimiento académico, y la RM demuestra ventajas en resultados cognitivos (d = 0.84) y conductuales (d = 0.40) en contextos de formación profesional. A pesar de estos beneficios, persisten barreras como los altos costos de implementación, la insuficiente capacitación docente y la escasez de investigación longitudinal. Esta revisión aporta una base de evidencia sintetizada para orientar políticas de tecnología educativa y práctica pedagógica.
