- ItemUnidimensionalidad del conocimiento matemático inicial de estudiantes para maestros(2021) Albarracín, Lluís; Rojas Letelier, Francisco; Chandía, Eugenio; Ubilla, F.; Gorgorio, NuriaEste trabajo presenta un estudio sobre la medición del conocimiento matemático inicial de los futuros maestros de Educación Primaria que han ingresado en el grado de maestro. Se ha utilizado un cuestionario que contiene dos tipos de ítems, respuesta abierta y respuesta cerrada. Han participado 125 estudiantes de la Universitat Autònoma de Barcelona (Barcelona) y 158 de la Pontificia Universidad Católica de Chile (Santiago de Chile). A partir de un estudio cuantitativo mediante análisis factoriales, se ha observado que este conocimiento se estructura de forma unidimensional, y se ha validado un conjunto de items para su medición estandarizada.
- ItemMind Wandering and Mindfulness During Innovation: An Outline and an Illustration in Poetry(Palgrave Macmillan, 2023) Preiss Contreras, David DanielI present an outline of the abilities and dispositions relevant for innovation in the twenty-first century. Explaining this outline, I discuss how intelligence and creativity relate to two attentional dispositions: mindfulness and mind wandering. I argue that understanding creative problem solving and innovation requires studying the interaction between intelligence, creativity, and these attentional dispositions. To do so, I summarize the twentieth-century maps of human intelligence and their limitations. Second, I use a computational metaphor to discuss the role of intelligence, creativity, and attentional dispositions in creative problem solving. Third, I review some evidence about the relationship between human abilities and attentional dispositions. Finally, to provide an illustration, I discuss the process of innovation in poetry.

- ItemTowards a Drought Monitoring, Tracking, and Management Platform Based on Quantitative Indices(2025) Gironás, Jorge; Núñez, Marialina; Vicuña, Sebastián; Aedo, Sebastián; Morales, David; Vargas, Javier; Guzmán, Juan de Dios; Suárez, FranciscoDrought is a complex phenomenon that affects the development and use of the country’s water resources. Characterization through indices is critical in planning, management, and decision-making to mitigate the effects of drought, mainly when these are implemented in online platforms for monitoring, warning, and tracking the phenomenon. These tools serve as a basis for implementing a set of measures focused on the short, medium, and long term, oriented to different audiences, and with differentiation of procedures and entities involved depending on the case. This work proposes the technical basis for elaborating preventive drought monitoring in Chile through a visualization platform. Based on a comparative analysis of international tools and the results of a consultation with experts, the relevant characteristics of a system for drought monitoring, follow-up, and management based on standardized drought indexes are analyzed. It is concluded that such a platform should consider multiple drought indices with different levels of severity for their classification. These indices should be automatically calculated using as much information as possible, both from national and international sources, from in-situ gauges as well as from satellite and remote sensing products, and even obtained from modeling. On the other hand, the visualization should be simple, straightforward, and flexible, and the information delivered should provide information on the manifestation of drought in the territory and its short-term forecast.
- ItemDefinition and Characterization of Drought(2025) Gironás León, Jorge Alfredo; Núñez Grahmann, Marialina I.Drought is a multifaceted and unpredictable climate event with profound effects on ecosystems, communities, and economies. This chapter explores the nature of drought, its origins, and provides defnitions tailored to various affected systems. Additionally, it presents related concepts while addressing potential misunderstandings and their consequences. The chapter also introduces statistical properties and indices for identifying and characterizing drought.
