In such settings, defenders allocate resources randomly to prevent attackers from anticipating their moves. As time evolves, the environment changes, and new strategies or actions may emerge. A suitable subfield of game theory to model these dynamics is stochastic games, where the state captures the set of available actions in a time-dependent process. Moreover, the attacker–defender inter- action naturally exhibits a hierarchical bilevel structure: the defender must design randomized strategies to protect targets, while the attacker responds by executing an action that maxi- mizes its reward. This makes stochastic dynamic Stackelberg games a model of choice for such applications [15], the Chilean party being very active in the domain [9, 10, 11]. In a previous collaboration [1], we have shown that defining an appropriate solution concept for these games is far from trivial, and in some cases remains an open research question. Even when a proper solution concept can be established, computing it becomes prohibitively expensive for games with massive state and action spaces. These challenges are not only of theoretical interest but also of high practical relevance. This associate team will focus on two among the many possible applications. Challenge 1: The first one is wildfire prevention. This theme has been widely examined in the literature, particularly through models that optimize the design of firebreaks [16], [12] and the the placement of surveillance cameras to limit fire spread. In contrast, the operational dimension of prevention and firefighting—where resources must be dynamically allocated un- der uncertainty—has received far less attention. Emerging distributed AI technologies with autonomous agents, both centralized (e.g., coordinated command-and-control systems) and de- centralized (e.g., drones and sensor swarms), could play a key role in addressing this challenge. Challenge 2: Similarly, in the domain of distributed AI learning systems (e.g. Federated Learning), a central authority is in charge of agregating the updates of distributed clients in the process of minimizing a global metric. The presence of Byzantine (or faulty) agents can derail convergence or induce a biais in this process. To mitigate this, robust agregation techniques have been proposed in the literature based on identifying and discarding suspect contributions [17, 18, 19]. But concrete attacks like ALIE [20] or FoE [21] tend to exhibit patterns. This lead researchers to propose the first history-aware defenses [22, 23, 24]. Purely deterministic rules, though, are likely to be defeated by powerful and well-informed agents. The attacker–defender framework is crucial to design secure training environments against adversarial manipulations, the principal issue being to decide if and when to exclude a suspected malicious agent. Both these applications can be tackeled with tools of Game Theory. More applications could be cited, like environmental conservation problems, such as poaching prevention [25], environmental tax evasion [26] or border patrol security [9].[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

En los últimos 5 años su exportación ha aumentado considerablemente ocupando el segundo lugar en este mercado. Derivado del procesamiento de los frutos se genera un alto porcentaje de pulpa y cáscara; residuos no aprovechables como subproducto para otras industrias como cuarta gama y/o farmacéutica. El elevado contenido antioxidantes de la sandía representa una oportunidad para su extracción y uso en otras industrias. La solución innovadora permitirá reutilizar grandes volúmenes de la pulpa y cáscara, mitigando su disposición inadecuada y mejorando prácticas agrícolas y biotecnológicas. El objetivo de la propuesta es desarrollar un paquete tecnológico consistente en tres aplicaciones que permiten valorizar los residuos de cáscara y pulpa de sandía para la producción de nutracéuticos, bioenmienda de suelos provenientes de relaves mineros, y sustrato para el crecimiento de microorganismos. El proyecto busca generar innovaciones que promuevan la transformación de los residuos agrícolas, proyectando así nuevos negocios para los productores hortícolas en la industria de los alimentos dando valor agregado a los residuos derivados del procesamiento de semillas. Los resultados esperados de esta iniciativa son: Portafolio de al menos 2 ingredientes funcionales (Licopeno y Citrulina) desarrollados y caracterizados; validación técnica del ingrediente principal (Licopeno o citrulina) con actividad antioxidante; bioenmienda validada en un entorno operacional (campo), alcanzando el nivel de madurez tecnológica TRL7; análisis de mercado robusto que incluye un plan de escalamiento técnico de la bioenmienda; medio de cultivo validado en un entorno operacional (empresas), alcanzando el nivel de madurez tecnológica TRL7; y análisis de mercado robusto que incluye un plan de escalamiento técnico.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Existing research has largely focused on isolated dimensions of this process—either legal, institutional, or perceptual—but has not addressed how these interact or differ in their consequences. This project addresses this gap by (a) proposing a multidimensional, contextually grounded, conceptual and operational definition of police empowerment and analyzing how its different components—moderated by accountability—affect public security and order, and the potential for police abuse. To achieve these goals, we adopt a multi-method design composed of six interrelated studies. These include expert interviews (Study 1), a longitudinal panel survey with citizens (EPSEP, Study 2), secondary data analysis (legal, institutional/administrative and authorities’ discourse analysis, Study 3), interviews with police officers (Study 4), a quasi-experimental study of the effect of key moments of empowerment (e.g., the enactment of a new law increasing police power, Study 5) on the aforementioned consequences, and an experimental study with police personnel (Study 6). Study 2 will also enable longitudinal, quasi- experimental (via a rolling cross-sectional design), and experimental analyses of the effects of police empowerment among citizens.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Increasing evidence of health benefits of the avocado is both driving increased consumption and stimulating research. Over the next few decades, a number of climate-related factors are expected to undergo significant change, leading to increases in CO2 and, depending on the region, temperature, humidity, salinity, flooding, and drought. Chile is expected to experience more frequent and severe flooding in the future due to climate change and sea level rise. By 2050, flooding in Chile could increase by an order of magnitude compared to the previous decade, while by the end of the century, Chile could experience more than 100 days of flooding each year. The frequency and severity of flooding will increase as sea levels rise. Under such predicted conditions, avocado orchards will suffer significant harm from waterlogging, which significantly will affect the growth, physiological performance and a general avocado production. The majority of avocado orchards are currently vulnerable to sporadic waterlogging as a result of climate change, either because of poor soil qualities or occasionally rising water tables. Waterlogging detrimentally affects avocado orchards at various levels. Reduced root and shoot growth due to soil oxygen depletion (plant-soil system), decreased transpiration rate, changes in the soil's oxidation-reduction status, decreased redox potential and ultimately decreased avocado production are the main effects of waterlogging on avocado. Climate change is increasing the frequency and severity of extreme weather events with flooding being the largest concern for Chile. Investigating how climate change factors combine with waterlogging stress, novel genes, and signaling components can provide useful insights into plant responses to waterlogging stress and future agricultural difficulties The species and occasionally the cultivar determine how long a plant may survive in a waterlogged condition. The rootstock (clonal or seedling rootstocks) used in the orchard may have an impact on the sensitivity to waterlogging. In this Project, it was hypothesized that: (1) Hass avocado grafted to different rootstocks (clonal or from seedling) may have a differential performance under waterlogging conditions and that the tolerance is driven by rootstock cultivar, stress severity, balance of oxidative stress and defense system at morpho-physiological, biochemical and molecular level and (2): Clonal o seedling rootstock influence Hass avocado responses to waterlogging by affecting root microbial community, carbon, nitrogen cycling and reduced soil components. Thus, the main objective of this proposal is to evaluate the effects of waterlogging on grafted Hass avocado to 04 different rootstocks (Dusa, Duke 7, Mexicola and Zutano) mainly used in the Central and South-Central region of Chile. A systematic fingerprinting analysis will be used in this project by integrating different tools for deep analysis (Chemo-Metabolomics, transcriptomics and metagenomics) and for monitoring changes in morpho-physiological and gas-exchange parameters, changes in plant-soil system by evaluating the composition and function of microbial communities within the pot soil in each treatment, the antioxidant defense system and reactive oxygen species, for better understanding the regulatory mechanisms of tolerance to waterlogging, identification of the potential genes regulating tolerance to waterlogging in Hass avocado and finally the selection of the rootstock with better agronomic performance. Four (4) different rootstocks will be used in this research (two hybrids from Mexican and Guatemalan races - Zutano and Dusa, two Mexican races - Mexicola and Duke 7) which will be grafted with the scion material collected from Hass avocado cultivar. Mexicola and Zutano Will be propagated by seeds; Duke 7 clonally propagated and clonal Dusa plantlets acquired in the national plant propagation nurseries due to protection of intellectual property. One year grafted Hass avocado on different rootstocks will be subjected to a waterlogging greenhouse experiment by submerging them in a plastic water tank with water level 5 cm above the soil Surface (140% field capacity) for 3, 6, 9, and 15 days against the control treatment (no waterlogging stress). Morphological, physio-biochemical and gas-exchange parameters, soil nutrient dinamics, function and composition of microbial community within the pot soil and sampling for transcriptomic analysis will then be performed. The results of this study are expected not only to provide more foundation into the agronomic, biochemical and molecular aspects associated to waterlogging of ‘Hass’ avocados grafted on different rootstocks but also provide potential biomarkers and genes involved in stress tolerance and select the best suited rootstocks for the current and the upcoming extreme climate change events, which may help to implement new Hass avocado production protocols that will reduce this predicted climate change problem in practice. This project will generate scientific and academic publications, extension and training of young researchers and will strengthen the network with national and international key partners. The findings will be also valuable for agronomists, plant physiologists, microbiologists and plant breeders to develop new avocado production protocols useful for waterlogging conditions that are predicted in Chile.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

No obstante, dicha mirada no siempre se refleja en la enseñanza de las matemáticas. Por ejemplo, estudios recientes revelan que los profesores de educación especial tienden a priorizar una enseñanza funcional de las matemáticas —como el manejo del dinero o actividades prácticas— con el fin de fomentar la autonomía y la inclusión laboral de estudiantes con discapacidad intelectual (San Martin et al., 2025). Si bien este enfoque puede ser valioso, centrar la enseñanza únicamente en lo funcional limita el acceso al desarrollo del pensamiento matemático, considerado un objetivo central del currículo escolar (e.g., Schoenfeld, 2022), y puede traducirse en una forma de exclusión que ha sido calificada como deshumanizante (Tan et al., 2020). Esto se debe a que, bajo el argumento de unas matemáticas funcionales, se recorta el currículo a estudiantes que presentan discapacidad o alguna barrera para el aprendizaje (Greenstein & Baglieri, 2018). Esta tendencia se ve reforzada por el predominio de la instrucción directa en la educación especial, que reduce las matemáticas a una secuencia de procedimientos por repetir (e.g., Gersten et al., 2009; Montague & Jitendra, 2012; Schnepel & Aunio, 2021), privando a los estudiantes de oportunidades para ejercer su capacidad de pensar y participar activamente en la construcción de significado (Lambert, 2018; Tan et al., 2020). En este contexto, este proyecto apunta a dos factores que podrían apoyar la superación de esta problemática: (a) el conocimiento matemático para la enseñanza de profesores de educación especial y (b) el uso de este conocimiento en tareas situadas, como atender al pensamiento matemático de los estudiantes. Para abordar este propósito, nos apoyamos en el conocimiento profesional para enseñar matemáticas, entendido en este trabajo a partir de tres constructos teóricos: (a) el conocimiento para la enseñanza de las matemáticas, desde dos perspectivas diferentes y complementarias —el Political Conocimiento for Teaching Mathematics (PCTM; Gutiérrez, 2012, 2017) y el Mathematics Teacher Specialised Knowledge (MTSK; Carrillo et al., 2018)—, y (b) el noticing multidimensional para la equidad (van Es & Sherin, 2021, 2022). La racionalidad de esta decisión radica en que los diversos modelos sobre el conocimiento del profesorado han evidenciado la complejidad de la relación entre el conocimiento matemático y su despliegue en las distintas prácticas que configuran la enseñanza de esta disciplina (Llinares, 2019). En este sentido, la investigación en torno al conocimiento del profesor de matemáticas se ha desarrollado principalmente desde dos enfoques (Depaepe et al., 2013; Kaiser et al., 2017): por un lado, una perspectiva cognitiva, que ha dado lugar a marcos teóricos que distinguen analíticamente distintas facetas del conocimiento; y, por otro, una perspectiva situada, que concibe el conocimiento docente como dinámico, emergente de la práctica y movilizado a través de la reflexión y la interacción en el aula. En este proyecto optamos por integrar ambas perspectivas, ya que, por una parte, están respaldadas teórica y empíricamente (Cenigz et al., 2011; Thomas et al., 2017) y, por otra, su articulación permite avanzar hacia una comprensión más holística del conocimiento profesional del profesorado que enseña matemáticas (Kaiser et al., 2014; Santagata & Yeh, 2016; Stahnke et al., 2016). Desde este marco, nos planteamos dos preguntas de investigación: ¿cómo se desarrolla el PCTM y el MTSK de los profesores de educación especial?, y ¿cómo se desarrolla el noticing multidimensional para la equidad en estos profesores? Estas preguntas se concretizan en el siguiente objetivo general: caracterizar el proceso de desarrollo del conocimiento profesional para enseñar matemáticas del profesorado de educación especial durante un curso de formación continua. Para el logro de este objetivo se ha diseñado una investigación basada en el diseño (Cobb et al., 2016; Molina et al., 2011). De manera general, este diseño contempla un primer año destinado a la revisión de la literatura, el diseño general del curso y de las entrevistas, la formación del facilitador y una primera recogida de datos mediante entrevistas. La implementación del curso de desarrollo profesional se realizará principalmente durante el segundo y tercer año. En el segundo año, el foco estará puesto en el desarrollo del PCTM y el MTSK mediante dos sesiones mensuales durante diez meses. Al finalizar este periodo, se repetirán las entrevistas personales con los participantes, ahora centradas en el desarrollo del PCTM y el MTSK. Durante el tercer año, el proyecto contempla la implementación de un club de video que seguirá el formato propuesto por van Es y Sherin (2008). Concretamente, se realizarán diez reuniones mensuales en las que se reflexionará en torno al marco del noticing multidimensional para la equidad (van Es & Sherin, 2022). Finalmente, durante el cuarto año, se realizará una tercera recogida de datos mediante entrevistas orientadas a indagar tanto el desarrollo del noticing como el uso de los modelos PCTM y MTSK. Estas entrevistas permitirán dar cuenta del proceso completo y serán analizadas en contraste con las dos recogidas previas. En este curso de desarrollo profesional participarán profesores de educación especial que se desempeñen actualmente en cursos de 1.º a 6.º básico, provenientes de cuatro contextos escolares en los que se despliega la educación especial: (a) escuelas para estudiantes sordos, (b) escuelas para estudiantes ciegos, (c) escuelas para estudiantes con TEA y (d) escuelas regulares con Programa de Integración Escolar (PIE). Los resultados esperables de este proyecto permitirán identificar áreas de conocimiento crítico que los profesores de educación especial necesitan para desempeñar con éxito la docencia en matemáticas. En este sentido, los hallazgos podrán orientar ajustes o propuestas para los programas de formación inicial docente, focalizando en aquellos aspectos que, tanto la literatura como los propios profesores en servicio, consideran necesarios para su desempeño profesional.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Specifically, this project will address open issues in the distributed control literature for microgrids; these include optimal parameter tuning and resilience to communications disturbances such as transport delays, packet loss, and communication failures due to cyberattacks. All of these are important components that prevent the proliferation of microgrid projects throughout the country and the world. Microgrids have the potential to improve the energy management of renewable resources and the resilience of current and future electrical systems. Furthermore, they aid in decarbonization and benefit the energization of isolated communities and national industries. Based on the above, the main objective of this research is to formulate, implement, and validate distributed intelligent controllers, using reinforcement learning, in agents that comprise interconnected AC/DC microgrids, in order to achieve optimal operation concerning available energy resources despite disturbances and failures in communication channels. To achieve this objective, the following specific objectives are specified: (i) investigate the state of the art in the use of reinforcement learning algorithms in cooperative multi-agent system control and their application to microgrids; (ii) design a deep reinforcement learning algorithm to auxiliary control an ILC of a hybrid AC/DC microgrid with communication loss and variable time delays; (iii) design a distributed controller with parameter and structure adjustment capability through deep reinforcement learning algorithms for the agents of an AC/DC multi-microgrid with communication losses and variable time delay; (iv) design a robust distributed controller through deep reinforcement learning algorithms that allows agents in an AC/DC multi-microgrid to be resilient to heterogeneous and variable transport delays, loss of data packets, and DoS cyber-attacks; (v) build a prototyping platform for multi-agent-based intelligent agent control schemes with digital twin co-simulation; (vi) implement and validate the proposed reinforcement learning controllers in an AC/DC multi-microgrid experimental setup.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
