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]

Cultural differences are significant for communication (Otten & Geppert, 2009) and teaching processes (Liddicoat & Scarino, 2013). Hence, intercultural interactions correspond to embodied culture discourses (Carbaugh, 2017; Shi-xu, 2023), which entail the communication practices that take place at institutional levels (i.e., top-down) and language classrooms (i.e., bottom-up). However, some tensions have been identified in these processes, particularly because they seem to maintain cultural and linguistic hierarchies that do not necessarily promote the social mobility or acceptance of minoritized groups (Flores & Rosa, 2015; Unamuno, 2016; Zavala, 2017). Against this backdrop, discursive practices are at the core of how these raciolinguistic hierarchies are maintained, negotiated, and/or challenged by educational communities. Consequently, the main objective of this research proposal is to examine how language and interculturality are discursively conceptualized and implemented in culturally diverse Chilean schools, specifically within three language subjects: Spanish, Ancestral Languages, and English as a Foreign Language. This objective is articulated through the following research question: How are language and interculturality discursively conceptualized and implemented in culturally diverse Chilean schools across the subjects of Spanish, Ancestral Languages, and English as a Foreign Language? To address this question, the project outlines four specific objectives (SOs): SO1) To examine how interculturality is discursively constructed in educational policies and the national curriculum on language subjects (i.e., Spanish, Ancestral Languages, and English as a Foreign Language); SO2) To assess how language teachers understand and implement intercultural practices in Chile, highlighting areas of convergence and divergence; SO3) To analyze how school communities discursively construct interculturality on their schoolscapes; and SO4) To analyze how language teachers’ actions and decisions address interculturality in the language classroom. The proposed research is a mixed-methods study (Creswell & Plano, 2018). First, we will analyze a corpus of institutional pedagogical discourses to examine how interculturality is discursively constructed in educational policies and the national curriculum (SO1). To this end, the data will be examined from a Corpus-Assisted Approach to Discourse Studies (CADS) (Partington et al., 2013) following the guidelines proposed by Jaworska and Kinloch (2018, p. 116) for a thorough and systematic examination of multiple datasets in CADS. The first quantitative stage considers the analysis of frequency, concordance lines, collocations, and keywords. The second qualitative stage is informed by Bacchi's (2012) model, What's the Problem Represented to be? (or WPR) and the Discourse-Historical Approach (Reisigl, 2017; Reisigl & Wodak, 2016). Second, we will conduct a questionnaire to identify how language teachers understand interculturality and intercultural practices in their classrooms (SO2). The sampling considers a disproportionate stratification to enable similar sample sizes for Spanish and EFL teachers, and Traditional Educators, ensuring the representation of Traditional Educators, who are the smallest population (CEM Mineduc, 2024). Third, we will analyze how school communities discursively construct interculturality on their school grounds (SO3) through the examination of schoolscapes (Gorter & Cenoz, 2015). To this end, three schools across three regions will be selected (i.e., Tarapacá, Metropolitan, and Araucanía) to ensure geographic representativeness. The data will be analyzed in light of Ledin and Machin’s multimodality framework (2017, 2018, 2019) as it incorporates the materiality of the semiotic signs, the ideologies and beliefs behind the creation of multimodal texts, and the recontextualization of social actors and practices (van Leeuwen, 2008). Finally, we analyze the actions and decisions language teachers take to address interculturality in the language classroom (SO4) through classroom observation (minimum 48 pedagogical hours in total; four hours per language subject) in the same schools. These observations will be analyzed using the synopsis technique (Dolz et al., 2018; Schneuwly & Dolz, 2009), which allows us to both hierarchize central pedagogical sequences and examine teachers' actions and students' reactions in detail. In turn, it enables data reduction and serves as heuristic support for analysis. Expected results seek to enlighten how educators co-create language and interculturality in culturally diverse schools. It examines how these social actors recontextualize and mediate top-down policies to their daily realities, thus illuminating the negotiation and resemiotization of hegemonic understandings of interculturality in line with the needs of their own communities (bottom-up practices).[/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]

To this end, three schools across three regions will be selected (i.e., Tarapacá, Metropolitan, and Araucanía) to ensure geographic representativeness. The data will be analyzed in light of Ledin and Machin’s multimodality framework (2017, 2018, 2019) as it incorporates the materiality of the semiotic signs, the ideologies and beliefs behind the creation of multimodal texts, and the recontextualization of social actors and practices (van Leeuwen, 2008). Finally, we analyze the actions and decisions language teachers take to address interculturality in the language classroom (SO4) through classroom observation (minimum 48 pedagogical hours in total; four hours per language subject) in the same schools. These observations will be analyzed using the synopsis technique (Dolz et al., 2018; Schneuwly & Dolz, 2009), which allows us to both hierarchize central pedagogical sequences and examine teachers' actions and students' reactions in detail. In turn, it enables data reduction and serves as heuristic support for analysis. Expected results seek to enlighten how educators co-create language and interculturality in culturally diverse schools. It examines how these social actors recontextualize and mediate top-down policies to their daily realities, thus illuminating the negotiation and resemiotization of hegemonic understandings of interculturality in line with the needs of their own communities (bottom-up practices).[/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]

Cultural differences are significant for communication (Otten & Geppert, 2009) and teaching processes (Liddicoat & Scarino, 2013). Hence, intercultural interactions correspond to embodied culture discourses (Carbaugh, 2017; Shi-xu, 2023), which entail the communication practices that take place at institutional levels (i.e., top-down) and language classrooms (i.e., bottom-up). However, some tensions have been identified in these processes, particularly because they seem to maintain cultural and linguistic hierarchies that do not necessarily promote the social mobility or acceptance of minoritized groups (Flores & Rosa, 2015; Unamuno, 2016; Zavala, 2017). Against this backdrop, discursive practices are at the core of how these raciolinguistic hierarchies are maintained, negotiated, and/or challenged by educational communities. Consequently, the main objective of this research proposal is to examine how language and interculturality are discursively conceptualized and implemented in culturally diverse Chilean schools, specifically within three language subjects: Spanish, Ancestral Languages, and English as a Foreign Language. This objective is articulated through the following research question: How are language and interculturality discursively conceptualized and implemented in culturally diverse Chilean schools across the subjects of Spanish, Ancestral Languages, and English as a Foreign Language? To address this question, the project outlines four specific objectives (SOs): SO1) To examine how interculturality is discursively constructed in educational policies and the national curriculum on language subjects (i.e., Spanish, Ancestral Languages, and English as a Foreign Language); SO2) To assess how language teachers understand and implement intercultural practices in Chile, highlighting areas of convergence and divergence; SO3) To analyze how school communities discursively construct interculturality on their schoolscapes; and SO4) To analyze how language teachers’ actions and decisions address interculturality in the language classroom. The proposed research is a mixed-methods study (Creswell & Plano, 2018). First, we will analyze a corpus of institutional pedagogical discourses to examine how interculturality is discursively constructed in educational policies and the national curriculum (SO1). To this end, the data will be examined from a Corpus-Assisted Approach to Discourse Studies (CADS) (Partington et al., 2013) following the guidelines proposed by Jaworska and Kinloch (2018, p. 116) for a thorough and systematic examination of multiple datasets in CADS. The first quantitative stage considers the analysis of frequency, concordance lines, collocations, and keywords. The second qualitative stage is informed by Bacchi's (2012) model, What's the Problem Represented to be? (or WPR) and the Discourse-Historical Approach (Reisigl, 2017; Reisigl & Wodak, 2016). Second, we will conduct a questionnaire to identify how language teachers understand interculturality and intercultural practices in their classrooms (SO2). The sampling considers a disproportionate stratification to enable similar sample sizes for Spanish and EFL teachers, and Traditional Educators, ensuring the representation of Traditional Educators, who are the smallest population (CEM Mineduc, 2024). Third, we will analyze how school communities discursively construct interculturality on their school grounds (SO3) through the examination of schoolscapes (Gorter & Cenoz, 2015). To this end, three schools across three regions will be selected (i.e., Tarapacá, Metropolitan, and Araucanía) to ensure geographic representativeness. The data will be analyzed in light of Ledin and Machin’s multimodality framework (2017, 2018, 2019) as it incorporates the materiality of the semiotic signs, the ideologies and beliefs behind the creation of multimodal texts, and the recontextualization of social actors and practices (van Leeuwen, 2008). Finally, we analyze the actions and decisions language teachers take to address interculturality in the language classroom (SO4) through classroom observation (minimum 48 pedagogical hours in total; four hours per language subject) in the same schools. These observations will be analyzed using the synopsis technique (Dolz et al., 2018; Schneuwly & Dolz, 2009), which allows us to both hierarchize central pedagogical sequences and examine teachers' actions and students' reactions in detail. In turn, it enables data reduction and serves as heuristic support for analysis. Expected results seek to enlighten how educators co-create language and interculturality in culturally diverse schools. It examines how these social actors recontextualize and mediate top-down policies to their daily realities, thus illuminating the negotiation and resemiotization of hegemonic understandings of interculturality in line with the needs of their own communities (bottom-up practices).[/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]
