Structural geology and geophysical constraints of the central-north part of the Sierra de Bonilla, Southern Precordillera, Argentina Sánchez, María Victoria; Ariza, Juan Pablo; Lince Klinger, Federico Gustavo; Boedo, Florencia Lucila; Gimenez, Mario Ernesto; Vujovich, Graciela Irene In central-western Argentina, an early Paleozoic belt comprising mafic and ultramafic rocks spatially associated with metasedimentary successions is exposed along the western margin of the Argentine Precordillera. In this study, we integrate structural and geophysical datasets to constrain the three-dimensional geometry of the southern sector of the Precordillera mafic-ultramafic belt, with focus on in the Sierra de Bonilla area. Structural analysis in the Quebrada Santa Elena evidences polyphase ductile deformation with sinistral shear components, while gravity and magnetic modeling reveal pronouced density and magnetic susceptibility contrasts consistent with the presence of serpentinite lenses at depth. This work refines the understanding of the crustal architecture of the southern Precordillera and provides new insights into the accretionary processes active along the Gondwananmargin during the early Paleozoic.

De los pasillos a las pantallas: La digitalización en la justicia penal argentina tras la covid-19; From the hallways to the screens: Digitalization in the Argentine criminal justice system following covid-19 Lio, Vanesa Gisela; Romero Marchesini, Natalia Durante la pandemia por la covid-19 las tecnologías digitales adquirieron un rol protagónico en Argentina. En el ámbito de la justicia penal, esto se reflejó en la aceleración de la transición hacia un sistema para tramitar electrónicamente los expedientes, lo cual permitió la automatización de algunos procedimientos, el inicio de la despapelización y la gestión remota de las causas. En el presente artículo se analizan, mediante la intersección entre la sociología de la justicia penal y los estudios sociales de la ciencia y la tecnología, los cambios que se produjeron con la incorporación de nuevas tecnologías en el registro y tramitación de las causas penales. El análisis se centra en la reconfiguración de tareas que fue necesaria para garantizar el acceso a la justicia en un contextode excepcionalidad, así como en los cambios que, más allá de la emergencia sociosanitaria, instauraron nuevos modos de acción. Desde un abordaje empírico centrado en un caso local y basado en el análisis documental y en la realización de entrevistas, se describen prácticas judiciales concretas con el fin de identificar los alcances y obstáculos que emergen en el encuentro de la justicia penal y las tecnologías en un escenario sin precedentes. Como resultado, se observa que esta integración no necesariamente conduce a una mayor democratización ni a un mejor acceso a la justicia.; During the covid-19 pandemic, digital technologies acquired a prominent role in Argentina. In the area of criminal justice, this was reflected in the accelerated transition towards a system of electronic processing of files, which allowed for the automatization of some procedures, the beginning of paperless processes, and the remote management of cases. Situated at the intersection of criminal justice sociology and science and technology studies, this article analyzes changes resulting from the incorporation of new technologies in the registry and processing of criminal cases. This analysis focuses on the reconfiguration of tasks that was necessary for guaranteeing access to justice in such an exceptional context, as well as changes that established new modes of action that have extended beyond the public health emergency. Through an empirical case study, based on documentary analysis and interviews, the article describes legal practices with the objective of identifying advances and obstacles that emerged from the encounter of criminal justice and technology in an unprecedented scenario. In conclusion, it is observed that this integration has not necessarily led to greater democratization nor to better access to the justice system.

Trayectorias de (des)identificación religiosa en personas LGBTNb+ de Argentina; Trajectories of Religious (Dis)identification in LGBTNb+ individuals in Argentina; Trajetórias de (des)identificação religiosa em pessoas LGBTNb+ da Argentina Rabbia, Hugo Hernán El estudio explora y caracteriza la adscripción religiosa y las trayectorias de (des)identificación religiosa en personas lesbianas, gays, bisexuales, trans - travesti, no binarias y de otras identidades sexogenéricas (identificadas con la sigla LGBTNb+) de Argentina. Se utilizaron datos cuantitativos del proyecto denominado Censo Diversidad, construidos a partir de un cuestionario online en un muestreo no probabilístico de N=15.204 personas autoidentificadas como LGBTNb+ mayores de 16 años y residentes en diversas regiones del país. En particular, se analizó la religión de crianza y la identificación religiosa actual, tanto de manera independiente, a partir del cruce con la identificación sexogenérica, edad, nivel educativo y región de residencia. Los resultados muestran que, si bien casi el 70% fue criado en el catolicismo, el 73% no se identifica con ninguna religión actualmente, siendo aún mayor la proporción en personas de menor edad, residentes en AMBA y Patagonia. Se identificaron también cinco trayectorias de movilidad religiosa: desidentificación religiosa (62% del total de respuestas), no religión constante (13,3%), identificación religiosa constante (11,4%), cambio interreligioso (8,7%) y conversión religiosa (4,1%). Crecer en entornos religiosos se asoció con mayores experiencias de rechazo familiar, sobre todo en segmentos de más edad. La desidentificación religiosa es significativamente superior a la población general, reflejando una reacción a la discriminación, pero también procesos complejos de búsqueda de espacios inclusivos, autonomía o resiliencia espiritual. Los hallazgos subrayan la necesidad de contextos afirmativos, incluyendo comunidades religiosas abiertas e inclusivas, para garantizar el bienestar de la diversidad sexogenérica.; The study explores and characterizes religious affiliation, and trajectories of religious (dis)identification among lesbian, gay, bisexual, trans - travesti, non-binary, and other sex-gender identities (under the acronym LGBTNb+) in Argentina. Quantitative data from Censo Diversidad were used, collected through an online questionnaire in a non-probabilistic sample of N=15,204 self-identified LGBTNb+ individuals aged 16 or older residing in all the regions of the country. Specifically, we analyzed religious upbringing and current religious identification, both independently and cross-referenced with sex-gender identification, age, educational level, and region of residence. Results show that, while almost 70% were raised as Catholic, 73% currently identify with no religion, with this proportion being even higher among younger individuals, and those residing in the Buenos Aires Metropolitan Area (AMBA) and Patagonia. We also identified five religious mobility trajectories: religious disidentification (62% of total responses), constant non-religion (13.3%), constant religious identification (11.4%), interreligious change (8.7%), and religious conversion (4.1%). Growing up in religious environments was associated with greater experiences of family rejection, especially among older segments. Religious disidentification is significantly higher than in the general population, reflecting a reaction to discrimination, but also complex processes of seeking inclusive spaces, autonomy, or spiritual resilience. The findings underscore the need for affirmative contexts, including open and inclusive religious communities, to ensure the well-being of sex-gender diversity.; O estudo explora e caracteriza a afiliação religiosa e as trajetórias de (des)identificação religiosa em pessoas lésbicas, gays, bissexuais, trans - travestis, não binárias e de outras identidades sexogênero (identificadas pela sigla LGBTNb+) da Argentina. Foram utilizados dados quantitativos do projeto denominado Censo Diversidade, construídos a partir de um questionário online em uma amostragem não probabilística de N=15.204 pessoas autoidentificadas como LGBTNb+ com mais de 16 anos e residentes em diversas regiões do país. Em particular, foram analisadas a religião de criação e a identificação religiosa atual, tanto de forma independente quanto a partir do cruzamento com a identificação sexogênero, idade, nível educacional e região de residência. Os resultados mostram que, embora quase 70% tenham sido criados no catolicismo, 73% não se identificam com nenhuma religião atualmente, sendo a proporção ainda maior em pessoas de menor idade e residentes na AMBA e na Patagônia. Foram também identificadas cinco trajetórias de mobilidade religiosa: desidentificação religiosa (62% do total de respostas), não-religião constante (13,3%), identificação religiosa constante (11,4%), mudança inter-religiosa (8,7%) e conversão religiosa (4,1%). Crescer em ambientes religiosos foi associado a maiores experiências de rejeição familiar, sobretudo em segmentos de maior idade. A desidentificação religiosa é significativamente superior à população geral, refletindo uma reação à discriminação, mas também processos complexos de busca por espaços inclusivos, autonomia ou resiliência espiritual. Os achados sublinham a necessidade de contextos afirmativos, incluindo comunidades religiosas abertas e inclusivas, para garantir o bem-estar da diversidade sexogênero.

Near-T vortex pinning and Dew–Hughes scaling in CaK(Fe1−xNix)4As4 and Ba(Fe1−xCox)2As2 single crystals Haberkorn, Nestor Fabian; Xu, M.; Schmidt, J.; Bud'ko, S. L.; Canfield, P. C. We compare pinning-force scaling in Fe-based superconductors exhibiting moderate vortex fluctuations using the Dew-Hughes formalism. Single crystals of CaK(Fe1−xNix)4As4 (1144) and Ba(Fe1−xCox)2As2 (122) are analyzed by fitting the normalized pinning force, , as a function of the reduced field near Tc, with the peak position at . In 1144, data are well described by single-peak scaling with h0 ≃ 0.30–0.34, consistent with predominant point-like disorder. In 122, h0 shifts from ≈ 0.17–0.23 in underdoped crystals and to ≈ 0.37–0.40 near optimal doping, indicating a mixed δTc/point pinning landscape. Literature datasets show that proton irradiation in lightly doped 1144 preserves a single peak near h0 ≈ 0.33, whereas heavy-ion irradiation in near-optimally doped 122 produces a high-field shoulder. Overall, Dew-Hughes scaling captures the main trends phenomenologically and provides a practical map linking the effective peak position h0 to the prevailing pinning landscape.

La juridificación de la cuestión campesina en Argentina (1990-2023); The juridification of the peasant question in Argentina (1990-2023) Barbetta, Pablo Nicolas En este trabajo me propongo analizar y comprender la juridificación del derecho a la tierra y al territorio que impulsan los movimientos campesinos en la Argentina para disminuir formas de exclusión del derecho al acceso a la tierra y/o en su derecho a conservarla. Metodológicamente, este trabajo se sustenta sobre la recopilación de fuentes secundarias en torno a leyes o proyectos impulsados desde las organizaciones campesinas en el lapso temporal de 1990 hasta 2023. A partir de ellas, sostengo que el despliegue de la lógica política campesina implicó un proceso de complejización en la juridificación de la cuestión campesina que se asienta ya no sólo en el derecho a la tierra sino también en el derecho al territorio. A partir de dicha distinción asistimos a un desplazamiento de un discurso del derecho de carácter distributivo en el caso del derecho a la tierra, hacia otro,dónde la búsqueda del reconocimiento de los derechos del ser, implica la emergencia de un derecho de carácter pluralista.; In this work, I propose to analyze and understand the juridification of the right to land and territory, focusing on the efforts of peasant movements in Argentina to reduce forms of exclusion from the right to access and/or retain land. Methodologically, this work is based on the compilation of secondary sources concerning laws and projects promoted by peasant organizations between 1990 and 2023. From these sources, I argue that the development of peasant political logic has led to a process of increasing complexity in the juridification of the peasant question, which is now based not only on the right to land but also on the right to territory. This distinction reveals a shift from a distributive legal discourse, in the case of land rights, to one where the pursuit of recognition of human rights implies the emergence of a pluralistic legal framework.

Automatic recalibration of quantum devices by reinforcing learning Crosta, T.; Rebón, Lorena; Vilariño, F.; Matera, Juan Mauricio; Bilkis, Matías During their operation, due to shifts in environmental conditions, devices undergo various forms of detuning from their optimal settings.Typically, this is addressed through control loops, which monitor variables and the device performance, to maintain settings at their optimal values. Quantum devices are particularly challenging since their functionality relies on precisely tuning their parameters. At the same time, the detailed modeling of the environmental behavior is often computationally unaffordable, while a direct measure of the parameters defining the system state is costly and introduces extra noise in the mechanism. In this study, we investigate the application of reinforcement learning techniques to develop a model-free control loop for continuous recalibration of quantum device parameters. Furthermore, we explore the advantages of incorporating minimal environmental noise models. As an example, the application to numerical simulations of a Kennedy receiver-based long-distance quantum communication protocol is presented.

Ambiente y Geopolítica: Aproximaciones en torno a la aprobación del proyecto Willow en el norte de Alaska; Environment and Geopolitics: Reflections on the Approval of the Willow project in Northern of Alaska Salvia, Agustín Ezequiel; Giammarino, Damián Ariel El presente trabajo tiene como objetivo explicar los hechos que dieron origen a la aprobación del proyecto Willow, de perforaciones petrolíferas en el norte de Alaska, por parte del gobierno de los Estados Unidos y, a raíz de esto, analizar los potenciales impactos económicos y ambientales que genera a nivel local, nacional y global. De esta forma, se intenta identificar cómo afectan los cambios dados por el contexto geopolítico en el comercio global, principalmente el de hidrocarburos, en el impulso desde Washington para nuevas perforaciones en todo el territorio y, por consecuencia, en la aprobación del proyecto Willow. A su vez, buscamos entender las lógicas territoriales locales del norte de Alaska y cómo la influencia intraescalar no es lineal, sino mucho más compleja.; This article examines the political, economic, and environmental dimensions surrounding the approval of the Willow Project, a large-scale oil drilling initiative in northern Alaska. The study begins by outlining the key events and policy decisions that led to its authorization by the U.S. federal government. We then analyze the potential local, national, and global impacts of the project, particularly in relation to environmental degradation and economic development. Special attention is given to the broader geopolitical context, especially the shifting dynamics of global hydrocarbon trade, which have influenced the U.S. government's strategic push for domestic energy production. Ultimately, the study argues that the approval of the Willow Project reflects not only a response to global energy pressures but also highlights the non-linear and multi-scalar nature of political and territorial decision-making in resource-rich regions.

Improved Radial-Based Noise Power Estimation in Dual-Polarization Weather Radars Using Adaptive F-Test Filtering Amoia, Matias Ezequiel; Hurtado, Martín; Fernández Michelli, Juan Ignacio This study presents an alternative radial-based algorithm for noise power estimation in dual -polarization weather radars. Polarimetric measurements provide valuable information about atmospheric phenomena. The cross-channel correlation between horizontal and vertical polarized signals allows the detection of noise-only range cells since weather signals typically exhibit high correlation, whereas noise does not. Based on this principle, the proposed approach replaces the median filtering in Beauchamp’s method with an iterative adaptive F-test, improving robustness to outliers. The algorithm is evaluated against both Beauchamp’s polarization-based scheme and Ivic’s nonpolarimetric method, demonstrating that it achieves a well-balanced tradeoff between accuracy and computational efficiency. Results using both simulated and real radar data support its suitability for operational implementation.

The Phylogenetic Data Matrices of Abelisauridae through Time and Methods (With Recommendations) Seculi Pereyra, Enzo Emanuel; Perez, Damián; González Dionis, Javier; Ezcurra, Martin Daniel The phylogenetic history of Abelisauridae has been reconstructed using an increasing number of taxa and different data matrices, many of which are derived from common sources. Despite this, the group still presents notable topological instability. Here, we systematically revise the 40 years of phylogenetic studies on Abelisauridae. We aimed to reconstruct a timeline of matrix iterations to address five key questions: 1) How the abelisaurid phylogenetic matrices changed over time in terms of character and taxon numbers; 2) How many authors have employed differential character weighting in their analyses; 3) What type of characters (e.g., discrete, continuous) have been used in the matrices; 4) What types of calibration methods have been used; and 5) Which were the main goals of these studies. Additionally, we provide recommendations for phylogenetic tree search strategies, time-calibration procedures, character weighting approaches, and the selection and use of data matrices. By synthesizing historical trends and current practices, our work highlights key limitations in the study of the abelisaurid relationships and suggests methodological improvements to strengthen future phylogenetic and macroevolutionary inferences in this clade.; La historia filogenética de Abelisauridae ha sido construida utilizando un número creciente de taxones y matrices de datos, muchas de ellas derivadas de fuentes compartidas. A pesar de ello, el grupo aún presenta una notable inestabilidad topológica con análisis filogenéticos bajo similares enfoques. En este trabajo, realizamos una búsqueda bibliográfica que abarca los 40 años de estudios filogenéticos sobre Abelisauridae. Nuestro objetivo fue reconstruir una línea de tiempo del desarrollo de las matrices para abordar cinco preguntas clave: 1) ¿Cómo han cambiado las matrices filogenéticas de Abelisauridae a lo largo del tiempo en términos de número de caracteres y taxones? 2) ¿Cuántos autores han empleado ponderación de caracteres en sus análisis? 3) ¿Qué tipo de caracteres (discretos o continuos) se han utilizado en las matrices? 4) ¿Qué tipos de métodos de calibración temporal se han aplicado? 5) ¿Cuál fue el objetivo principal de estos estudios? Además, proporcionamos recomendaciones sobre estrategias de búsqueda filogenética, procedimientos de calibración temporal, enfoques de ponderación de caracteres, y la selección y uso de matrices de datos. Al sintetizar las tendencias históricas y las prácticas actuales, nuestro trabajo destaca limitaciones clave en el estudio de las relaciones dentro de Abelisauridae y sugiere mejoras metodológicas para fortalecer futuras inferencias filogenéticas y macroevolutivas en este clado.

La autoconstrucción de la vivienda en México: fuentes y materiales para pensar aportes a la historia de la arquitectura; Self-built housing in Mexico: sources and materials for thinking contributions to the history of architecture; A autoconstrução de moradias no México: fontes e materiais para refletir sobre contribuições para a história da arquitetura Durante, Maria Eugenia ¿Quiénes y qué han escrito sobre los procesos de autoconstrucción de vivienda en México? ¿Cómo se legitimaron e institucionalizaron estas formas de producción del espacio? El presente artículo indaga en aportes de diversos campos de estudio y ámbitos de producción intelectual, rastreando los materiales locales que durante la segunda mitad del siglo XX se abocaron a estudiar, analizar y debatir sobre los procesos de autoconstrucción de la vivienda en México. La investigación se apoya en un trabajo de revisión bibliográfica y recurre a herramientas de la historiografía para desplegar la reflexión sobre quiénes escribieron, en qué contextos y qué aportan para pensar una historia de la autoconstrucción.

Producción académica sobre educación STEM/STEAM en Latinoamérica y el papel de la matemática: una revisión sistemática de la literatura; Academic production on STEM/STEAM education in Latin America and the role of mathematics: a systematic literature review Alonso, Jonathan Marcelo; Villarreal, Monica Ester Este artículo presenta una revisión sistemática de literatura sobre educación STEM/STEAM en Latinoamérica, basada en 141 artículos publicados en 73 revistas académicas de Ciencias Sociales y Educación entre 2016 y 2023. El análisis consideró la evolución temporal, la distribución geográfica, los niveles educativos, los tipos de trabajo, las temáticas de investigación y la presencia de la matemática en los artículos de investigación. Los resultados muestran un incremento sostenido de publicaciones a partir de 2020, con predominio de trabajos desarrollados en el nivel de educación superior, estudios investigativos y fuerte representación de Brasil. Se identificaron dos grandes grupos de estudios investigativos: aquellos que emplean STEM/STEAM como etiqueta genérica, centrados en problemáticas de género y trayectorias estudiantiles en carreras STEM, y aquellos que conciben STEM/STEAM como enfoque educativo integrador, donde prevalecen estudios de experiencias educativas y sobre competencias y habilidades relacionadas con el enfoque. Se detectaron vacancias en torno a currículum, evaluación y formación docente, así como un tratamiento limitado de la matemática, que suele ocupar un papel secundario en las experiencias educativas con enfoque STEM/STEAM. Estos hallazgos permiten mapear tendencias y vacíos en la región, aportando orientaciones para futuras investigaciones.; This article presents a systematic literature review on STEM/STEAM education in Latin America, based on 141 articles published in 73 Social Sciences and Education journals between 2016 and 2023. The analysis considered temporal evolution, geographic distribution, educational levels, types of work, research themes, and the presence of mathematics in research articles. The results show a steady increase in publications since 2020, with a predominance of studies conducted at the higher education level, a strong prevalence of research work, and a significant representation of Brazil. Two main groups of research studies were identified: those that use STEM/STEAM as a generic label, focusing on gender issues and student trajectories in STEM careers, and those that conceive STEM/STEAM as an integrative educational approach, where studies on educational experiences and on competencies and skills related to the approach prevail. Gaps were detected regarding curriculum, assessment, and teacher education, as well as a limited treatment of mathematics, which often plays a secondary role in STEM/STEAM-oriented educational experiences. These findings provide a mapping of trends and gaps in the region, offering guidance for future research.

The 36 Cl Bomb‐Pulse in Ice at a High‐Accumulation Site in Antarctica Fifield, L. Keith; Etheridge, David M.; Di Tada, Mariana; Liu, Kexin; Cresswell, Richard G.; Keywood, Melita D. The radioisotope 36Cl was produced prolifically by nuclear weapons testing, principally at Bikini and Enewetak Atolls in the1950s. Much of this was injected into the stratosphere, from where it was dispersed worldwide. The fallout of this bomb‐produced 36Cl has been measured as a function of time in an ice core from a high‐accumulation site in Antarctica. These measurements complement an earlier study in an Arctic ice core. A box model has been developed to describe simultaneously the data from both the two sites. Using an up‐to‐date catalog, the36Cl production of the individual tests has been estimated and used as input to the box model. Production is dominated by high‐yield thermonuclear tests carried out on barges moored in the lagoons of the atolls in the1 950s. Exchange times of 3.7 years for gaseous exchange between stratosphere and troposphere and 4.2 years for gaseous exchange between the stratospheres of the two hemispheres are deduced. The 36Cl bomb pulse constitutes a global tracer with an input function that is well‐defined in space and time, and its exchange between stratosphere and troposphere is dominated by one‐way transport due to its rapid removal once in the troposphere. This latter behavior greatly simplifies the interpretation of the data in terms of an exchange time relative to the 14C bomb pulse. The stratosphere‐troposphere exchange time derived here from the bomb produced 36Cl offers an independent constraint on the flux of ozone between stratosphere and troposphere which agrees well with other more direct estimates.

Alternancia política y dinámicas electorales en Corea del Sur: la elección presidencial de 2022 y sus múltiples dimensiones; Political Alternation and Electoral Dynamics in South Korea: The 2022 Presidential Election and its Multiple Dimensions Bavoleo, Bárbara Inés; Benítez, Matías; Chaure, Desirée La elección presidencial de 2022 en Corea del Sur representó un momento clave de alternancia política, en un contexto marcado no solo por la crisis sanitaria global de la COVID-19, sino también por tensiones sociales y económicas que venían acumulándose desde antes. Este artículo examina cómo ese recambio en el poder fue mucho más que una rotación de partidos: puso en juego disputas sobre el rumbo del país, la representación de sectores históricamente marginados y la manera en que se interpreta y ejerce el pluralismo democrático. A partir de un enfoque que entrecruza factores como la experiencia pandémica, el rol decisivo del voto joven, los debates en torno al feminismo y las brechas estructurales en el acceso a vivienda y empleo, se reconstruye el ascenso de Yoon Suk-yeol, un outsider conservador que supo canalizar el descontento ciudadano. Sin embargo, la deriva autoritaria de su gobierno y su destitución tres años después invitan a repensar los alcances reales del cambio político en democracias consolidadas. El trabajo propone así una lectura amplia del caso surcoreano, que pone en diálogo el momento electoral con los desafíos más persistentes de su institucionalidad democrática.; The 2022 presidential election in South Korea marked a pivotal moment of political alternation, set against the backdrop of a global health crisis and long-standing socio-economic tensions. This article explores how the power shift represented more than just a change in governing parties—it sparked debates about the country’s direction, the inclusion of marginalized groups, and the very foundations of democratic pluralism. By examining the impact of the pandemic, the decisive role of young voters, rising anti-feminist sentiment, and structural challenges like housing and labor inequality, the study traces the rise of Yoon Suk-yeol, a conservative outsider who capitalized on widespread public discontent. Yet, the authoritarian drift of his administration and his eventual impeachment three years later call into question the actual transformative power of political change in consolidated democracies. This article offers a comprehensive reading of the South Korean case, linking its electoral dynamics with broader institutional challenges.

El suicidio policial en Argentina: Aportes para la comprensión del fenómeno en clave sociológica (2016-2023); Police suicide in Argentina: Contributions to the understanding of the phenomenon in a sociological key (2016-2023) Galar, Santiago El artículo se propone dimensionar, describir y analizar desde una perspectiva sociológica el fenómeno del suicidio en personal de las Fuerzas Federales de Argentina en el período 2016-2023. El análisis repara en tres dimensiones de los suicidios policiales:características de estos fenómenos, narrativas sobre los factores de riesgo policial y sobre las circunstancias precipitantes. El estudio integra diversas estrategias, fuentes y temporalidades: repone y conceptualiza información difundida por instancias gubernamentales, reconstruye el punto de vista de los actores a partir de entrevistas en profundidad e incorpora un conjunto de materiales diversos, como normativa, notas en prensa y datos estadísticos. El artículo constituye un primer acercamiento a la temática que habilita un mayor conocimiento sobre el volumen y las características del suicidio policial.Además, los elementos presentes en el análisis evidencian que los suicidios constituyen muertes difíciles de procesar institucionalmente en parte porque los actores problematizan dos dimensiones, la laboral y la personal, que la institución intenta constantemente mantener unidas.; The article aims to measure, describe and analyze from a sociological perspective the phenomenon of suicide in personnel of the federal forces of Argentina in the period 2016-2023. The analysis focuses on three dimensions of police suicides: characteristics of these phenomena, narratives about police risk factors and about the precipitating circumstances. The study integrates different strategies, sources and temporalities: identifies and conceptualizes information publicized by government agencies, reconstructs the actors' point of view from in-depth interviews and adds a set of diverse materials, such as legislation, press releases and statistical data. The article is a first approach to the subject that enables to increase knowledge about the volume and characteristics of police suicide. Furthermore, the elements present in the analysis show that suicides constitute deaths that are difficult to process institutionally partially because the actors problematize two dimensions, the work dimension and the personal dimension, that the institution constantly tries to keep together.

COURSE: Cross-scale cOUpling pRocesses in the Solar–tErrestrial system—SCOSTEP’s new program for 2026–2030 Laurenza, M.; Shiokawa, K.; Molina, Maria Graciela; Liu, H. L.; Krivova, N. A.; Funke, B.; Kusano, K.; Habarulema, J. B.; Buresova, D.; West, M. J.; Chau, J.; Zhang, J.; Nesse, H.; Usoskin, I.; Alberti, T.; Alfonsi, L.; Coddington, O.; Dasso, Sergio Ricardo; Fung, Shing F.; Hayakawa, Hisashi; Miyoshi, Y.; Nakamura, R.; Temmer, M.; Stolle, C.; Zong, Q. G.; Briand, C.; Goplaswamy, N.; Safranova, Jana The committee nominated to define the Scientific Committee on Solar–Terrestrial Physics (SCOSTEP) Next Scientific Program (NSP) has identified cross-scale coupling as the overarching theme for conducting and promoting coordinated research and outreach activities in the upcoming period 2026–2030. The program is called COURSE (Cross-scale cOUpling pRocesses in the Solar–tErrestrial system) and is organized in three main scientific focus areas: 1) sources of space weather and space climate; 2) solar wind, magnetosphere, and ionosphere coupling; and 3) external impacts and internal dynamics of the Earth atmosphere. For each Focus Area the NSP committee has identified: 1) long-standing goals, i.e., key questions persistent through SCOSTEP scientific programs and 2) objectives, i.e., precise outcomes that can be addressed over the 5-year program duration, which contribute to achieving the goals over the long term. Moreover, the committee envisions the implementation of the program through identified novel methods, including machine learning and Artificial Intelligence techniques; integrated models; new missions; the combination of multipoint in-situ data with ground observations; improved metadata; and adoption of Findable, Accessible, Interoperable, and Reusable (FAIR) principles.

Precariado y Política: Emprendedurismo y juventudes mejoristas; Precariat and Politics. Entrepreneurship and youth “mejoristas”; Precariado e Política. Empreendedorismo e juventude “mejorista” Welschinger Lascano, Nicolás Sebastían; Seman, Pablo Federico En este artículo sostendremos que el triunfo del mileísmo se alimentó de una transformación sociolaboral que ocurrió en los sectores medios y populares argentinos que vivieron el estancamiento económico de los últimos diez años junto con la crisis de la pandemia, las restricciones de la cuarentena, la reconfiguración del mundo laboral y la espiralización de la inflación. A la victoria de Milei le precede un cambio socio laboral y cultural, un cambio en la sociedad que encontró un actor capaz de performatizar los reclamos de una mayoría que creció a espaldas de y contra la representación política tradicional: la emergencia de una sensibilidad popular que llamamos “mejorismo”. Nuestra tesis es que una de las sedes cruciales de la sensibilidad “mejorista” son las juventudes con trabajos informales y que el triunfo electoral de Milei y la consolidación inesperada de su gobierno se deben en gran parte a que el “mejorismo”, que es parte del apuntalamiento electoral de Milei, es también el sostén del gobierno libertario. Sobre la base de un trabajo etnográfico, a lo largo del artículo describimos el “mejorismo” como la sensibilidad popular emergente que afirma la autonomía individual de los sujetos frente al Estado y la política, que cree que el mejor desempeño social posible se logra a través del esfuerzo personal. El artículo explora la relación entre la producción de la subjetividad mejorista y los nuevos liderazgos políticos que dieron lugar a la afinidad ideológica y política entre importantes sectores de las juventudes con trabajos informales y el programa libertario.; In this article we will argue that the triumph of Mileism was fueled by a socio-labor transformation that occurred in the Argentine middle and popular sectors that experienced the economic stagnation of the last ten years along with the pandemic crisis, quarantine restrictions, the reconfiguration of the labor world and the spiraling inflation. Milei's victory was preceded by a socio-labor and cultural change, a change in society that found an actor capable of performing the claims of a majority that grew up behind and against traditional political representation: the emergence of a popular sensibility that we call "mejorismo." Our thesis is that one of the crucial sites of the "mejorista" sensibility is the youth with informal jobs and that Milei's electoral victory and the unexpected consolidation of his government are largely due to the fact that "mejorismo," which is part of Milei's electoral support, is also the support of the libertarian government. Based on ethnographic work, throughout the article we describe “mejorismo” as the emerging popular sensibility that affirms the individual autonomy of subjects in the face of the State and politics, which believes that the best possible social performance is achieved through personal effort. The article explores the relationship between the production of “betterism” subjectivity and the new political leaderships that gave rise to the ideological and political affinity between important sectors of youth with informal jobs and the libertarian program.; Neste artigo argumentaremos que o triunfo do mileísmo foi nutrido por uma transformação sócio- trabalhista ocorrida nos setores médios e populares argentinos que vivenciaram a estagnação econômica dos últimos dez anos juntamente com a crise pandêmica, as restrições de quarentena, a reconfiguração do o mundo do trabalho e a espiral da inflação. A vitória de Milei é precedida por uma mudança sócio- laboral e cultural, uma mudança na sociedade que encontrou um ator capaz de cumprir as demandas de uma maioria que cresceu atrás e contra a representação política tradicional: o surgimento de uma sensibilidade popular que chamamos de “mejorismo”. ” Nossa tese é que um dos assentos cruciais da sensibilidade “melhorista” são os jovens com empregos informais e que a vitória eleitoral de Milei e a consolidação inesperada de seu governo se devem em grande parte ao fato de que o “mejorismo”, que faz parte do sistema eleitoral de Milei, apoio, é também o apoio do governo libertário. Com base no trabalho etnográfico, ao longo do artigo descrevemos o “mejorismo” como a sensibilidade popular emergente que afirma a autonomia individual dos sujeitos frente ao Estado e à política, que acredita que o melhor desempenho social possível é alcançado através do esforço pessoal. O artigo explora a relação entre a produção de subjetividade melhorista e as novas lideranças políticas que deram origem à afinidade ideológica e política entre importantes setores da juventude com empregos informais e o programa libertário.

Articulación entre las estrategias ambientales de las PyMEs turísticas de servicios y la percepción de los turistas: un análisis en el marco de la responsabilidad social empresarial; Linking Environmental Strategies of Tourism Service SMEs and Tourists’ Perceptions: An Analysis within the Framework of Corporate Social Responsibility Sales, Romina Giselle Las pequeñas y medianas empresas (PyMEs) del sector de servicios turísticos han adoptado estrategias de responsabilidad social empresarial enfocadas en la sustentabilidad. Estas incluyen la optimización del consumo energético, la gestión de residuos y la implementación de modelos de economía circular, con el objetivo de mejorar su competitividad y compromiso ambiental. En Argentina, donde el turismo es un pilar fundamental de la economía, las PyMEs de alojamiento representan una parte importante del sector. Sin embargo, muchas implementan estrategias sustentables sin conocer en profundidad las expectativas ambientales de los turistas, lo que puede llevar a decisiones poco valoradas por los usuarios. Además, la falta de visibilidad de estas iniciativas limita su impacto en la sensibilización del público. En este contexto, el presente artículo propone analizar la relación entre las estrategias ambientales implementadas por las PyMEs turísticas en el marco de la RSE y la percepción ambiental de los turistas. Asimismo, se busca reflexionar sobre la importancia de visibilizar las prácticas sostenibles adoptadas por estas empresas. Al explorar estas cuestiones, se afirma que el análisis de la percepción ambiental y las estrategias de difusión promovidas por el Estado son factores clave para potenciar las PyMEs.; Small and medium-sized enterprises (SMEs) in the tourism services sector have adopted corporate social responsibility (CSR) strategies focused on sustainability. These include the optimisation of energy consumption, waste management, and the implementation of circular economy models, with the aim of improving their competitiveness and environmental commitment. In Argentina, where tourism is a fundamental pillar of the economy, accommodation SMEs represent a crucial part of the sector. However, many of them implement sustainable strategies without a deep understanding of tourists' environmental expectations, which can lead to decisions that are not highly valued by customers. Furthermore, the lack of visibility of these initiatives limits their impact on public awareness. In this context, this article proposes analysing the relationship between the environmental strategies implemented by tourism SMEs within the framework of CSR and the perception that tourists have of these initiatives. It also aims to reflect on the importance of making the sustainable practices adopted by these companies visible. In exploring these issues, it is argued that the analysis of environmental perception and the visibility strategies promoted by the state are key factors in empowering SMEs.

Topic-dependent relation prediction in argument mining: ternary classification Schmidt, Federico Martín; Gottifredi, Sebastián; García, Alejandro Javier The automatic identification of interactions among arguments expressed in natural language is a complex task that is mandatory for applications that need automatic argumentative reasoning. In this work, we focus on the prediction of relations between arguments, aiming to determine how a piece of text interacts with a specific discussion topic. Specifically, we aim to identify whether the text attacks, supports, or remains neutral toward a given topic. We frame this problem as a ternary classification task, and evaluate several methods for addressing it, including methods based on the combination of binary classifiers, models following a multitask learning approach, and large language models using prompting strategies. All our experiments were performed in a cross-topic scenario using two corpora, one of which includes more than 300 discussion topics, which brings our approach closer to a real-world scenario.
