When the public believes in the police's legitimate authority, they are likelier to follow their orders and cooperate with law enforcement. Conversely, perceptions of unjust behavior, such as not allowing citizens to explain themselves during interactions (procedural injustice), can lead to defiance of police orders (defiant motivational postures). In fact, over recent decades, we have witnessed numerous violent protests, police brutality, and human rights violations by police forces worldwide, including in Chile. The Carabineros, Chile's primary police force, were once highly trusted by the Chilean population. However, incidents of corruption and excessive use of force during the October 2019 social outbreak severely damaged public trust in the police (Instituto Nacional de Derechos Humanos [INDH], 2021). Therefore, it is crucial to understand the extent to which individuals perceive the police as acting fairly and correctly (i.e., procedural justice) and how they interact with and view the police in Chile (i.e., motivational postures). Additionally, it is well documented in the international literature that people who belong to minority groups (such as migrants, indigenous people, black Americans, among others) may have more tense interactions with the police and suffer higher levels of discrimination when interacting with police officers. Particularly, in Chile, there is evidence that police forces have used, both historically and in the present day, excessive use of force in particular against minority groups, namely among Mapuche people, immigrants living in Chile, as well as youths from low socioeconomic backgrounds. Therefore, we argue that these interactions between citizens and police are not only theoretically significant but also have societal implications, potentially influencing levels of conflict or cohesion within a community. Furthermore, international studies have also shown that disproportionate use of force by law enforcement often targets marginalized communities, particularly minority groups. Members of these groups also experience higher levels of discrimination compared to more privileged social groups within specific contexts (Feldman et al., 2019; Gee & Ford, 2011). Such experiences erode trust in law enforcement and may provoke protests against the police or demands for police reforms, as well as the avoidance of the police, even their work may be necessary (Woods et al., 2015). Therefore, understanding the interplay between perceptions of procedural justice (Lind & Tyler, 1988; Tyler & Lind, 1992) and motivational postures (Braithwaite, 2003) is crucial for understanding police-minority interactions. In this light, the current project aims to understand how police-minority interactions in Chile are experienced and perceived in terms of procedural justice and motivational postures by considering the perspectives of three minority groups (namely, Mapuche people, immigrants living in Chile, and youths from low socioeconomic backgrounds) and police officers. To our knowledge, there is a scarcity of studies focusing on police-minority interactions in Chile. Thus, by developing three interconnected studies with minority group members (Studies 1 and 3) and police officers (Study 2), this project’s expected results aim to, firstly, contribute to the state-of-the-art from a theoretical perspective, with the aim of advancing our understanding of police-minority interactions, through a combination of different frameworks combining procedural justice and motivational postures. Second, from a practical standpoint, we aim to generate empirical evidence that enables our understanding of police- minority interactions and provide practical guidelines and public policy recommendations about ways in which minority-police interactions can improve and lead to higher levels of procedural justice and more compliance with law enforcement. To achieve our main objective, we will conduct three interconnected studies. First, we will implement a longitudinal qualitative analysis through focus groups with minority group members (Study 1). Secondly, we will conduct semi-structured interviews with police officers (Study 2) and, finally, we will conduct an experimental study to test the causal relationship between procedural justice and motivational postures from the perspective of minority group members (Study 3). Data will be collected in the North (Antofagasta), Center (Santiago) and South (Temuco) of Chile). We expect to publish four articles in peer-reviewed journals, organize three academic seminars with national and international scholars, and present our findings in different national and international conferences. We will also organize four dissemination activities with policy makers and Human Rights Organizations concerned with police violence and how this phenomenon particularly affects minority groups, as a means to contribute to and potentially influence the development of public policies in the area of police- minority interactions. Finally, we also aim to disseminate our results among Carabineros and other relevant actors within Chilean society, as well as civil society in general.[/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]

In Stage 1, we will assay the effect of BCRNFs on N-dynamics and chemical soil properties through soil incubations performed under controlled conditions for 90 days. We will measure N-losses periodically through volatilization of NH3 and NO2. Additionally, we will quantify potentially mineralizable nitrogen (PMN), changes in the C:N ratio, and changes in pH and soil nutrient content during nine sampling dates. In Stage 2, two independent experiments will be conducted to evaluate the interaction among BCRNFs with soil and its effect on the morphological, physiological, and biochemical plant adaptive strategies related to NUE. In Experiment 1, wheat will be harvested at the pre-anthesis growth stage, and plant growth parameters and N concentration in tissues will be used to determine N uptake efficiency (NUPE). Additionally, it will measure plant adaptative strategies related to N-uptake, such as root architecture, exudation of organic acids by roots, and changes in enzymatic and microbial activities in the soil. In Experiment 2, wheat plants will be harvested at the maturity stage to evaluate the relationship between grain yield and N concentration to determine N utilization efficiency (NUTE). Plant adaptive strategies related to NUTE will also be assessed, including N-translocation and remobilization, CO2 assimilation rate (A), stomal conductance (gs), photosynthesis per unit of N, PNUE. In addition, the leaf response to the fluorescence and stay green trait will also be performed. The amount of nitrogen in grain derived from the fertilizer (Ndff) will be calculated using the δ15N values obtained from grains. In Stage 3, the effect of BCRNFs on wheat productivity and nutritional quality will be evaluated in field conditions. The trials will be conducted over two agricultural seasons, and the impact of BCRNFs on soil and plant samples will be assessed at three different stages: anthesis, soft dough grain, and hard dough grain. During these stages, the chemical properties of the soil, as well as microbial and enzymatic activities, will be evaluated. Photosynthetic parameters such as A, gs, Ci, E, Fo, Fm, and QY will be quantified. The plant height, harvest index, and yield components will be assessed at the end of each growing season. Grain quality indicators like protein content, gluten levels, and sedimentation rate will also be measured. Finally, the amount of nitrogen in grain derived from the fertilizer (Ndff) will be calculated using the δ15N values obtained from grains. This proposal focused on understanding the interconnections among soil, N-fertilizer, and plant physiology, using wheat as a model crop. The primary aim is to boost N management strategies in agriculture, ensuring a balance between productivity and sustainability. The initiative seeks to create a technological solution to enhance NUE, reduce environmental impact, and ensure global food security.[/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]

Wearable technologies, which integrate advanced computing and electronics into clothing and accessories, have seen significant global adoption since the early 21st century due to the miniaturization of computational devices. These technologies offer continuous, fluid, and hands-free operations, transforming them into an extension of the body and mind. Their applications span various domains, including health and fitness, medical applications, consumer electronics, military uses, and fashion. Despite their benefits, wearable technologies present technical and ethical challenges, particularly concerning privacy, data analysis, and surveillance. In Chile, wearable devices are increasingly used to monitor health variables, although detailed data on their adoption rates among the general population is limited. Studies indicate a growing interest in integrating these technologies into healthcare practices, suggesting potential widespread use in the near future.[/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]

Moreover, it is the main socialisation space that provides the youth with broader social relationships compared to the intimate social context of the family (Vincent et al., 2018). This Fondecyt project will ethnographically analyse the school’s role in socialising attitudes towards socioeconomic inequality among secondary students in classrooms with a diversified socioeconomic composition. Studying these attitudes is crucial since they might symbolically legitimise or challenge the existing social order (Sandel, 2021) and contribute to the reproduction or transformation of socioeconomic inequalities (Alesina et al., 2012). Since evidence on this issue is key for democratic governments in socioeconomically unequal societies to inform policies for reducing inequality and increasing social cohesion, the project focuses on Chile, a country with extreme levels of socioeconomic inequality (WID, 2022). By identifying opportunities and challenges for schools to promote egalitarian attitudes towards socioeconomic inequality among their socioeconomically diverse students, the project will provide decisive evidence for education policy to improve their support to school communities. The general objective of this project is to analyse how the schools contribute to shaping attitudes towards socioeconomic inequality among secondary students in classrooms that have diversified their socioeconomic composition. The specific objectives are as follows: 1. To characterise the socioeconomic heterogeneity within schools with secondary education in Chile and identify those that have diversified the socioeconomic composition of their students in the last decade. 2. To determine the schools’ pedagogical, organisational and community responses to the increase in their socioeconomic diversity and examine how these responses promote particular attitudes towards socioeconomic inequality. 3. To describe the students' inter-class relationships and identify how these relate to particular attitudes towards socioeconomic inequality, including awareness of inequality, perceptions of the fairness of social inequalities, meritocratic beliefs, and egalitarian preferences. The study will use a sequential mixed methods design, with a first quantitative phase aimed at answering Specific Objective 1 and informing the selection of the sample of schools for the second - ethnographic - phase, which is the predominant one and seeks to answer Specific Objectives 2 and 3: a) Quantitative phase: A Socioeconomic Diversity Index (SDI) will be created using data from the Quality of Education Agency through its SIMCE questionnaire to parents of secondary students for 2014-2024, which asks about the families’ socioeconomic information. Descriptive statistics will be used to describe SDI and its temporal variation by school. b) Ethnographic phase: Ethnographic fieldwork will be deployed in three schools with increased socioeconomic diversity, as measured in the SDI. Fieldwork in each school will last approximately two months, and the following methods will be used: - Interviews with staff members: 10 in each school (30 total), including the Principal, two Deputy Principals, three professionals from a psychosocial support team and four teachers. - Friendship maps and interviews with students: Maps of the students’ social relationships will be built with secondary students, seeking to include the whole class in each school (approximately 100 students in total). Maps will be followed by interviews. - Observations: They will be conducted in classrooms, playgrounds, and school events for approximately 100 hours in each school (approximately 300 hours of observation in total). The expected results include a) a map of all Chilean schools according to their current socioeconomic diversity and its temporal variation; b) in-depth evidence of inter-class relationships between secondary students and how these affect their attitudes towards socioeconomic inequality; and c) a systematisation of the schools’ responses to the students’ socioeconomic heterogeneity, their links to the development of attitudes towards socioeconomic inequality, and their facilitating and hindering elements. These findings will be useful for other schools that are diversifying their student body, wish to do so, or are interested in promoting egalitarian attitudes among their students. Ultimately, the project will provide critical evidence for public policy to promote schools that foster the development of egalitarian attitudes and potentially contribute to reducing social inequalities.[/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]

Drought intensification has been projected to increase in frequency in several regions across the globe, including the southwestern part of South America, the European Mediterranean Basin, Northern Africa, the Middle East, Central Asia, Australia, and the USA. Particularly, the former three areas have been recognized as locations highly likely to face unprecedented droughts during the 21st century, and within Southwestern South America, Chile has been alarmingly pointed out as the country earlier in this era experiencing this phenomenon, regardless of the greenhouse gas emissions scenario. Catastrophic effects such as extreme droughts and changes in fire behavior are important drivers of ecosystem degradation in arid, semiarid, dry temperate and Mediterranean ecosystems. Mediterranean ecosystems of central Chile have been indicated as the earliest in its type experiencing effects of climate change; where an accelerated aridification is already registered; therefore, representing a scenario to anticipate the effects of climate anomalies at other ecosystems of its type. Persistent droughts and land burning can compromise belowground conditions that are essential to support aboveground life in terrestrial ecosystems. Nevertheless, despite their importance for ecosystem functioning and recovery after environmental disturbances, there still a considerable lack of comprehension on how belowground attributes respond to combined stressors such as droughts and fires. This is of particular concern in conditions where post-fire plant and soil recovery have been shown to be inhibited or retarded due to severe droughts. Therefore, this project aims to evaluate individual and combined effects of drought and fires over time in soil microbial communities and carbon and nitrogen functional dynamics along with the relationship of these attributes and the state of sclerophyll vegetation in Mediterranean forests of central Chile. To accomplish this goal a multiscale approach will be applied in this research by integrating scientific disciplines from landcape ecology to molecular biology. By using remote sensing study site will be selected within an area known to be affected by an extended drought period (since 2010), in addition to hyper-dry years (2019 and 2021), which in addition has experienced the occurrence of historical wildfires as the case of 2017. From this initial screening 18 study conditions resulting from three climate anomaly categories identified (high, medium, low) according to differences in precipitation with respect to historical average, three categories for forest response to drought (recovered, unaffected and unrecovered) based on analysis of Normalized Burn Index (NBR = [NIR - SWIR] / [NIR + SWIR]) and two burned conditions (with and without) will be obtained for soil and vegetation assessments. Classical soil physicochemical analyses and NG-sequencing techniques including high-throughput amplicon sequencing (metabarcoding), whole genome sequencing (metagenomics), and gene expression (metatransciptomics), in addition to soil physiological analyses will be performed. Moreover, vegetation recovery following drought and fire will be evaluated. Results from this study will allow to better understand the individual versus the combined effects of drought and fires in soil microbial community structure and carbon and nitrogen functionality, which are expected to be exacerbated with the combined occurrence of these phenomena, giving insights on the resilience capacity of soil microbiomes and carbon and nitrogen biogeochemical cycles. From this work, results will also allow to gain a more comprehensive understanding of the linkages between soil functionality and vegetation responses to drought and fires over time, which will allow to identify ecological drivers related to ecosystem stability.[/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]

These objects are central to questions in algorithmic design, where we aim to program a computer to efficiently perform tasks involving them. These tasks may include counting objects based on certain parameters, sampling an object uniformly at random, optimizing with respect to an objective function, searching for objects that satisfy specific properties, or generating all objects exactly once. This project focuses on two of these problems: combinatorial generation and the search for highly distinct combinatorial objects. While many of the aforementioned tasks have general-purpose techniques that allow them to tackle multiple problems simultaneously, the situation becomes less clear when dealing with combinatorial generation or the search for distant objects. Much of the effort in these areas has been devoted to developing ad hoc methods. Despite this, these last two problems can be naturally phrased in the language of flip graphs, which encode the similarity between combinatorial objects. In this context, the problem transforms into the traditional graph problems of Hamiltonicity (finding a path that traverses all the vertices exactly once) and diameter (finding two vertices that are farthest apart). Recent research has highlighted the significant value of exploiting polytopal properties and symmetry of flip graphs, leading to unified frameworks that can address many problems simultaneously. The main objective of this project is to contribute to this perspective. Specifically, it aims to enhance our understanding of the polytopal and symmetric properties of flip graphs and use this knowledge to develop efficient algorithms for tackling Hamiltonicity and diameter problems[/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]
