Corporizar la escritura. Pedagogía teatral y educación imaginativa en la formación de educadores infantiles
(Universidad Finis Terrae, 2026-07-16) Araujo Escobar, Junell Lorena; Sánchez-Duque, Carmen Gloria; Barrera-García, Ángela
La presente investigación analiza el impacto del juego dramático fundamentado en la educación imaginativa sobre el rediseño de planificaciones curriculares para la alfabetización inicial. Mediante una metodología cualitativa de investigación-acción, estudiantes de Educación Infantil participaron en un taller vivencial diseñado para cuestionar y superar los enfoques tradicionales de enseñanza. El análisis documental de las propuestas curriculares elaboradas evidenció una ruptura crítica de las inercias técnico-conductistas e instrumentales detectadas en el hito diagnóstico preliminar. Los resultados confirman una evolución metodológica hacia diseños curriculares de carácter artístico, experiencial y creativo, favorecida por el desarrollo de la comprensión somática. Se concluye que la integración del juego dramático y la educación imaginativa permite corporizar el aprendizaje de la lengua escrita al articular emoción, imaginación y experiencia lúdica. Esta hibridación pedagógica constituye una alternativa sólida para transformar la enseñanza mecánica de la alfabetización en una experiencia significativa, participativa y profundamente vinculada con el desarrollo integral de los estudiantes.

Enhancing grid stability and sustainability through virtual power plants: A case study of Chile.
(Elsevier, 2026-07-17) Yanine, Fernando; Masrur, Hasan; Montoya, Fernando; Hidalgo, Mauricio
The rapid growth of distributed solar photovoltaic (PV) generation in urban power networks has intensified challenges related to frequency stability, voltage regulation, and overall power quality, particularly in regions with high penetration of small- and medium-scale distributed generation (PMGD). This study evaluates the role of Virtual Power Plants (VPPs) as coordinated control mechanisms to mitigate these disturbances. A simulation-based framework is developed using representative operational data from ENEL Distribución Chile, combined with dynamic system modeling implemented in Python. Three operating scenarios are analyzed: (i) PMGD without VPP support, (ii) PMGD with integrated VPP coordination, and (iii) reduced PMGD capacity with and without VPP intervention. The analysis focuses on system-level dynamic response, including frequency, voltage, and phase behavior under high-generation conditions. Results demonstrate that VPP deployment significantly enhances grid stability, reducing frequency deviations from 0.5 Hz to 0.1 Hz and voltage fluctuations from 5% to 2%, while improving overall power quality metrics by approximately 80%. These findings confirm the effectiveness of coordinated VPP control in managing power imbalances and stabilizing renewable-rich distribution networks. The proposed approach provides a practical and scalable framework for integrating distributed renewable generation, offering insights for utilities and policymakers in Latin America and similar high-penetration contexts.

La sexualización de la geopolítica: masculinidades, afectos y arribismo social en "El que merodea en la lluvia" (1962) de Hugo Correa
(Index Copernicus Sp, 2026-07-20) Salas Camus, Pedro Pablo
La novela El que merodea en la lluvia (1962) de Hugo Correa, pionero de la ciencia ficción chilena moderna, versa sobre Salvador, un oficinista bancario de clase media, cuya búsqueda de ascenso social se entrelaza con sus deseos sexuales y su incapacidad para controlar sus emociones. Mi hipótesis es que el relato puede leerse como una alegoría de las frustraciones de la clase media chilena y la subordinación del país en el contexto internacional, en donde los elementos de ciencia ficción del relato tienen el rol de propiciar una realización simbólica que compensan y corrigen, por un lado, la subordinación de la clase media chilena a la oligarquía local, y por el otro, la dependencia de Chile con respecto a las superpotencias globales (EE. UU., URSS). Asimismo, por medio de un análisis centrado en la representación de las masculinidades, postulo que la inversión de roles entre subordinado y amo radica, en esencia, en la proximidad o lejanía del concepto de masculinidad hegemónica (Connell 1997, Bonino Méndez 2002) de los personajes masculinos de la novela.

Low-renin hypertension in incidental adrenal adenomas and response to aldosterone-targeted therapy: a prospective study
(Elsevier, 2026-06-27) Uslar, Thomas; Sanfuentes, Benjamín; Olmos, Roberto; Burnier, Alberth; Böhm, Pauline; Guarda, Francisco J.; Huete, Álvaro; Mertens, Nicolás; Besa, Cecilia; Andía, Marcelo; Majerson, Alejandro; Cartes, Jaime; Tapia-Castillo, Alejandra; Carvajal, Cristian A.; Fardella, Carlos E.; Allende, Fidel; Solari, Sandra; Vaidya, Anand; Baudrand, Rene
Background: Incidental adrenal adenomas are common, yet renin status is infrequently assessed in hypertensive patients. Emerging evidence supports a spectrum of renin-independent aldosterone excess associated with adverse cardiovascular risk. Objective and methods: To determine the frequency of a low-renin phenotype in a prospective cohort of hypertensive patients with adrenal adenomas and to evaluate the clinical response to aldosterone-targeted therapy across baseline aldosterone categories. Low-renin phenotype was defined as suppressed renin (PRA <1.0 ng/mL/ h or DRC <10 μIU/mL). Among these patients, plasma aldosterone concentration (PAC) was categorized as 5–10 ng/dL (Group 1), 10–15 ng/dL (Group 2), and >15 ng/dL (Group 3). Patients with suppressed renin were treated with MR antagonists or adrenalectomy and followed longitudinally using PAMO/PASO criteria. Results: Low renin was present in 47% (138/290) of hypertensive patients. Increasing aldosterone levels were associated with higher systolic blood pressure (SBP), resistant hypertension, higher antihypertensive treatment burden, lower potassium, and reduced eGFR (p-trend <0.001). After a mean follow-up of 24±18 months (n = 121), aldosterone-targeted therapy (75% medical, 25% surgical) led to significant reductions in SBP (-18, -26, and -30 mmHg across Groups 1–3; all p < 0.001), decreased medication and significant increases in renin (all p < 0.001), irrespective of aldosterone category. Conclusions: Nearly half of hypertensive patients with adrenal incidentalomas exhibit suppressed renin levels associated with greater blood pressure burden and favorable response to aldosterone-targeted therapy, even in lower aldosterone levels categories. These findings support systematic renin assessment in hypertensive patients with incidental adrenal adenomas and provide a rationale for testing aldosterone-targeted therapy in broader hypertensive populations beyond adrenal adenomas

A bi-objective optimization model to plan vaccination campaigns aided by temporary centers
(Wiley, 2026) Montenegro-Dos Santos, Fernando; Pérez-Galarce, Francisco; Monardes-Concha, Carlos A.; Cruz-Zárate, Sergio; Candia-Véjar, Alfredo
Vaccination campaigns have saved thousands of lives and reached even the world’s most remote areas. However, the COVID-19 pandemic significantly changed the strategies for such campaigns. It is now crucial to rigorously consider new factors when planning the operational aspects of these campaigns, particularly for last-mile vaccine dispensing. First, a large share of the population must be vaccinated, with emphasis on vulnerable groups at higher risk. Second, if the virus is highly contagious and capable of asymptomatic transmission, implementing public health measures at vaccination sites becomes paramount. To address these challenges, we propose a bi-objective optimization model to support healthcare decision-making. It defines a schedule for locating temporary vaccination centers and assigning populations to permanent and temporary sites over a planning horizon. Moreover, we formalize and validate a minimum set of properties for a function-based prioritization mechanism to ensure consistent prioritization. One objective prioritizes vaccinating vulnerable groups according to our novel function-based approach, while the other minimizes the operational costs of temporary centers. In the complex environment of a pandemic, the strategic integration and use of temporary and permanent vaccination centers is vital for creating a robust and responsive vaccination strategy. Temporary centers, whose locations are determined by the model, improve access for hard-to-reach groups, contribute to minimizing crowding at permanent sites, and lower infection risks. Our results, demonstrated through a case study, show that the model effectively allocates resources and generates various vaccination plans that cater to different priority levels assigned to each objective, thereby offering valuable decision support.
