Delineating genomic features for wild guanaco conservation Leggieri, Leonardo Ramón; Anello, Melina; Peralta, Diego Matias; Tunez, Juan Ignacio; Di Rocco, Florencia; Poljak, Sebastián; Flores, Celina Eliana; Alunni, Daniela Verónica; Belardi, Juan Bautista; Gutierrez, Maria Amelia; Alvarez, María Clara; Massigoge, Agustina; Kaufmann, Cristian Ariel; Borrero, Luis Alberto; Borghi, Carlos Eduardo; Demartini, Julieta Paola; Petracci, Pablo; Martín, Sotelo; Marbán, Leandro Martín; Kathiravan, Periasamy; Rudolf, Pichler; Valdez Marín, Juan Carlos; Cárcamo, Juan Guillermo; Carmanchahi, Pablo Daniel The South American fauna has endured challenges such as illegal hunting, cattle expansion, climate change, and landscape fragmentation. Despite ongoing conservation efforts that aim to address these issues, genetic diversity remains overlooked. We genotyped 126 Lama guanicoe individuals from an area of 2 million km2 in Patagonia and Cuyo using the 60K SNPs Axiom-Camelids, and we assessed population viability through genetic diversity, inbreeding, and population size. We then explored population connectivities through network analyses, genetic differentiation, and Bayesian approaches. Our findings reveal six genetic clusters: Cuyo, Somuncura, North Patagonia, Central Patagonia, South Patagonia, and Tierra del Fuego Island (TDFI). Cuyo and TDFI guanacos differed from others due to isolation-by-distance and geographical barriers, respectively. Cuyo exhibited the highest degree of allele conservation, but TDFI faced heightened vulnerability due to isolation and increased homozygosity. Sharp bottlenecks in Cuyo and North Patagonia coincided with the expansion of sheep farming, while bottlenecks in the other populations occurred during the Little Ice Age. North Patagonia acted as a probable contact zone, facilitating mixing of the Cuyo, Somuncura, and Central Patagonia populations. The Central and South Patagonian populations presented the highest gene flow. Thus, genomic advances help to define distinct conservation units (genetic stocks) to guide management practices and decisions.

Assembling the Brazilian flora: overview of Leguminosae diversity Morim, Marli Pires; Filardi, Fabiana Luiza Ranzato; Sartori, Ângela Lúcia Bagnatori; Simon, Marcelo Fragomeni Simon; Iganci, João Ricardo Vieira; Lewis, Gwilym P.; de Lima, Haroldo Cavalcante; Lughadha, Eimear Nic; Fernandes, Moabe Ferreira; de Queiroz, Luciano Paganucci; Cardoso, Domingos; Morales, Matias Over the last two centuries, since the treatment of Leguminosae in Flora Brasiliensis, many new legume species and genera have been described, adding to the accumulated body of knowledge on species’ circumscriptions and distribution, published in monographs, taxonomic revisions and regional floristic treatments of specific Brazilian phytogeographic domains. The Flora do Brasil 2020 project was a collaborative effort conducted between 2008 and 2020 to meet the targets set by the Global Strategy for Plant Conservation, an initiative of the Convention on Biological Diversity. The project aimed to inventory and revise the taxonomy of all plant species in Brazil, including Leguminosae. The monograph of the legume family was carried out by a team of 102 taxonomists (10% of the project’s total), who worked towards updating and verifying the taxonomy of these plants in an online platform. Information on the life forms, substrate, endemism level, and geographical distribution for all accepted taxa were provided, alongside morphological descriptions, identification keys, images of herbarium specimens and field photographs. In this work, we have extracted from the Flora do Brasil 2020 project the legume data consolidated on December 31st, 2020 to provide an overview of the species diversity of Leguminosae in Brazil and its distribution across phytogeographic domains. The results revealed that the family is represented by 220 genera, of which 19 are endemic, and a total of 2901 species (1576 endemic). After fully monographing 210 genera (95%), we showcased Leguminosae as the most diverse family in the country, representing 6% of the total vascular plant species documented in the Flora do Brasil 2020. The species are found in all phytogeographic domains, exhibiting a wide range of life forms. The Mata Atlântica and Caatinga domains together contain the largest number of endemic legume genera in Brazil, most of them monospecific.A discussion on the conservation status of the Brazilian legume species is also provided. Knowledge of the Brazilian flora is continuously advancing, particularly with regards to Leguminosae, demanding regular taxonomic and nomenclatural updates.Current collaborations have greatly improved our understanding of legume diversity and distribution, providing evidence to inform conservation prioritization and action for the Leguminosae in Brazil’s megadiverse flora.

Cuidados alimentarios de niños, niñas y adolescentes de familias usuarias de un comedor popular del asentamiento urbano La Carbonilla Comelatto, Agustina; Gonzalez, Yamila Anahi; Grabowiecki, Paula Valeria; Marsilla, Malena; Mancinelli, Gloria En los últimos años, el concepto de cuidado infantil ha ido variando y surge como relevante en un contexto donde el cuidado empieza a pensarse como una actividad que requiere ser problematizada, dando lugar a un enriquecedor campo de discusión. El presente trabajo de investigación busca analizar y comprender la articulación entre los diferentes actores, instituciones y el cuidado alimentario de niños, niñas y adolescentes (NNyA) de familias que asisten al comedor popular “Polo Obrero La Carbonilla” situado en dicho barrio, considerando la influencia de factores socioculturales y económicos en la formación de sus hábitos alimentarios. Para llevar adelante el estudio elegimos un enfoque cualitativo, y para la recolección de datos utilizamos fuentes primarias como la observación participante, entrevistas en profundidad y encuestas, y también fuentes secundarias como páginas web e informes de centros de investigación, que permitieron complementar los datos recogidos en terreno. La investigación nos permitió desentrañar el concepto de cuidado de NNyA, un proceso sociocultural, el cual consideramos como una vía de acceso para explorar conceptos de construcción de la niñez en diferentes situaciones y contextos. Además, observamos que el rol de los comedores populares es fundamental no sólo para asegurar el derecho de NNyA a no padecer hambre, sino también como un espacio donde se resalta la relevancia del cuidado como una acción social, colectiva e interdisciplinaria.; In recent years, the concept of childcare has been changing and emerges as relevant in a context where care is beginning to be thought of as an activity that requires to be problematized, giving rise to an enriching field of discussion. The present research work seeks to analyze and understand the articulation between the different actors, institutions and the nutritional care of children and adolescents (C&A) from families that attend the “Polo Obrero La Carbonilla” soup kitchens located in said neighborhood, considering the influence of sociocultural and economic factors in the formation of their eating habits. To carry out the study, we chose a qualitative approach and for data collection we used both primary sources such as participant observation, in-depth interviews and surveys, as well as secondary sources such as websites and reports from research centers, which allowed us to complement the data collected on the ground. The research allowed us to unravel the concept of child care, a sociocultural process, which we consider as an access route to explore concepts of childhood construction in different situations and contexts. Furthermore, we observed that the role of soup kitchens is fundamental not only to ensure the right of children and adolescents to not suffer from hunger, but also as a space where the relevance of care as a social, collective and interdisciplinary action is highlighted.

Advancing the design of heterogeneous catalyst: Copper-montmorillonite for regioselective alkyne hydroamination Alonso, María Belén; Radivoy, Gabriel Eduardo; Mancebo Aracil, Juan Transition metal catalysts supported on natural materials offer promising avenues for sustainable organic synthesis. In this study, we present the synthesis, characterisation, and catalytic performance of copper nanoparticles supported on montmorillonite K10 (CuMK10) as a heterogeneous catalyst for hydroamination reactions. CuMK10, synthesised through a robust and established nanoparticle synthesis methodology, demonstrates remarkable catalytic efficiency and selectivity in the synthesis of imines via hydroamination of terminal alkynes. The catalyst exhibits exceptional regioselectivity, predominantly yielding Markovnikov products, demonstrating its potential as a versatile tool in organic synthesis. Moreover, CuMK10 shows favourable reusability, offering economic benefits and practical utility due to its ease of recovery and reuse. Comprehensive structural and mechanistic studies provide insights into the catalyst's performance, paving the way for the development of efficient and environmentally benign catalytic systems.

Tunneling Current Calculation Using the Linear-Bound Potential Model Ferreyra, Jorge Mario; Bridoux, German; Villegas Andina, Atuel Elías; Tolosa, Martín Rodrigo; Villafuerte, Manuel Jose A model of the tunneling current through an ultrathin insulating barrier comingfrom carriers in an inversion layer using a simple linear potential model ispresented. This model provides analytical expressions for the wavefunctions ofthese carriers and simple equations to obtain numerically their correspondingeigenvalues. These expressions can be inserted in the tunneling current equationallowing a more simple understanding of the physics involved in this tunnelingproblem. As an example, one can fit the experimental results for the leakagecurrent obtained by different authors in planar metal oxide semiconductor fieldeffect transistors and also in a LaAlO3/SrTiO3 and a HfO2/Ge bilayer. Themodification of the tunneling current when the dielectric constant is increased,a subject of interest in device applications, is explored.

Geografía física en clave de desempeño académico: El caso de las carreras de turismo de la Universidad Nacional de Tierra del Fuego; Physical Geography in code of academic performance: The case of Tourism courses at the National University of Tierra del Fuego Schwartz, Soledad; Villarreal, María Laura; Alli, Pamela Daniela El rendimiento estudiantil o desempeño académico constituye una variable útil para pensar en la calidad de la educación superior. No obstante, existen diversas acepciones en torno a su medición. En este marco, el presente artículo tiene como objetivo conocer las características de dicho desempeño en términos del cursado de la asignatura Geografía Física del primer año de las carreras Tecnicatura y Licenciatura en Turismo de la Universidad Nacional de Tierra del Fuego, Antártida e Islas del Atlántico Sur. Para ello, y bajo un enfoque cuantitativo de alcance exploratorio, se consideró a los estudiantes inscriptos en la materia durante los años 2018 a 2023 y el concepto obtenido en base a la normativa de la universidad, así como la inscripción a mesa de examen final hasta agosto de 2024. A través de las actas de inscripción, de regularidad y de examen, se construyó una matriz de doble entrada incluyendo a un universo de 911 estudiantes. El análisis revela que el 17% pierde la cursada por no cumplimentar requisitos de admisión en tiempo y forma, que la tasa de abandono temprano ronda el 27%, que el 36% queda libre por diversos motivos y que la tasa de regularidad alcanza el 19%. Asimismo, se observa que solo el 12,37% de los estudiantes logró acreditar la asignatura mediante la aprobación del examen final, varios de ellos luego de haber cursado la asignatura en más de una oportunidad. Estos primeros resultados en relación a la problemática del desempeño académico abren interrogantes para profundizar en variables cualitativas que permitan comprender los motivos de deserción y las estrategias de éxito de los estudiantes para delinear así acciones institucionales que aumenten la permanencia y el posterior egreso.; Student academic performance is a useful variable to think about the quality of higher education. However, there are different ways to measure it. In this sense, the present article aims to explore the characteristics of such performance in the subject Physical Geography of the first year of the degree in Tourism at the national university of Tierra del Fuego, Antártida e Islas del Atlántico Sur. For this purpose, and under a quantitative approach, the students enrolled in the subject during the years 2018 to 2023 were considered and the concept obtained based on the university regulations, as well as the registration to the final exam until August 2024. Through these records, a double-entry matrix was designed including a universe of 911 students. The analysis reveals that 17% do not fulfill admission requirements in time, that the early dropout rate is around 27%, that 36% fail for various reasons, and that the regularity rate reaches 19%. Likewise, it is observed that only 12.37% of the students manage to pass the final exam, many of them after having taken the course on more than one occasion. These first results in relation to the problem of academic performance raise questions that invite us to deepen the analysis taking into account qualitative variables to understand the reasons for dropout and the success strategies of students in order to outline institutional actions that increase permanence and the subsequent graduation.

Poderes públicos, territorio, población. La democracia en la teoría del Estado Nosetto, Luciano Ezequiel “¿Podemos reflexionar sobre el Estado desde una teoría del Estado? ¿Desde una teoría que no tenga por centro a la democracia, sino que ponga lo democrático a jugar en el interior de un conjunto más vasto, de fenómenos sociológicos y jurídicos, que involucran el territorio, la población y los poderes?”, se pregunta Luciano Nosetto en este texto que se vale de autores como como Georg Jellinek, Max Weber y Carl Schmitt para acercar conceptos con los que comprender los dilemas y las posibilidades a las que abre la situación de nuestro tiempo. Situación dramática “que hizo posible que el procedimiento jurídico de formación de la voluntad gubernamental diera lugar al nihilismo activo, esto es, al encumbramiento de la voluntad de destrucción como voluntad rectora del Estado”.

Changes in least limiting water range under different tillage systems and traffic intensities in a subhumid pampean region Vallejos, Adrián Gustavo; Iglesias, Julio Osvaldo; Galantini, Juan Alberto; Imhoff, Silvia del Carmen Soil management practices can disrupt soil structure, affecting productivity through changes in water and oxygen availability, and mechanical impedance. These variables can be affected by machinery traffic depending on the management practice used. This research aimed to quantify changes in the least limiting water range (LLWR) in the surface soil layer under varying traffic intensities in both no-till (NT) and conventional tillage (CT) systems. The treatments applied to each system were: control without any traffic (0P), one tractor pass (1P), and five tractor passes (5P). To determine the LLWR and available water (AW), the following variables were measured: soil bulk density (BD), soil water retention curve (SWRC) and soil penetration resistance (SRP). Transit treatments gave different LLWR results depending on tillage system. The changes in AW were less sensitive than the LLWR values. The only treatment that did not reach the critical bulk density (BDc), where the LLWR is zero, was the 0P treatment. Both the NT and CT 1P treatments reached the same BDc of 1.39 m³ m- ³. However, in the 5P treatment, the BDc was 1.33 m³ m- ³ for CT and 1.41 m³ m- ³ for NT, respectively. The LLWR showed a different response of its structural condition to the tillage system and traffic intensity in both tillage systems. These results provide evidence of a greater risk of soil degradation under CT than under NT management. Regardless of soil management and machinery traffic treatments, soil penetration resistance was the attribute that had more influence on the LLWR.

A simple and fast method to calculate the coil currents and the external poloidal flux and magnetic field for fixed boundary equilibria Farengo, Ricardo; Garcia Martinez, Pablo Luis; Ferrari, Hugo Emilio A simple and fast method to calculate the coil currents and the external poloidal flux and magnetic field consistent with a given internal magnetohydrodynamic (MHD) equilibrium and coil geometry is presented. The constrained optimization technique employed allows to fix the exact position of the X-points. The external poloidal flux and field are calculated using Green´s functions expressed in terms of elliptic integrals that are calculated using a fast and accurate routine. The calculation can be limited to the region between the plasma and the device wall. An example for a double null configuration is presented.

Una propuesta de teoría sociológica: Los poderes reclasificatorios; Uma proposta de teoria sociológica: Poderes reclassificatórios; A proposal for sociological theory: Reclassificatory powers Bialakowsky, Alejandro Marcos Este artículo presenta una propuesta de teoría sociológica a partir de los poderes reclasificatorios. Hoy se despliegan constantes disputas sobre los modos de dividir, calificar y jerarquizar el mundo social y natural. Son las maneras de reclasificar con sus alcances prácticos –colectivos y personales–, como desigualdades, discriminaciones, regulaciones, innovaciones, etc. Tales disputas van desde recategorizaciones de “género”, “clase” y “étnico-raciales” hasta “jurídicas”, “económicas”, “religiosas” o “técnicas” vía algoritmos. Así, resulta fundamental elaborar una perspectiva teórico-analítica en sociología que dé cuenta de esas controversias. Ésta requiere una mirada de conjunto, abstracta e incisiva, evitando fragmentaciones teóricas del Sur y del Norte. Para ello, se realizan unas primeras definiciones del concepto de “poderes reclasificatorios”. Luego se enfoca en sus divisiones y capacidades para abordar las relaciones entre poder y dominación, en particular, con algunos ejemplos de la sociología argentina. Por último, se mencionan ciertos elementos de continuidad de la propuesta.; Este artigo oferece uma proposta de teoria sociológica baseada nos poderes reclassificatórios. Hoje há contínuas disputas sobre as formas de dividir, classificar e hierarquizar o mundo social e natural. São os modos de reclassificação com as suas implicações práticas ‒coletivas e pessoais‒ como as desigualdades, as discriminações, as regulamentações, as inovações, etc. Essas disputas vão do recategorizações de “género”, da “classe” e da “raça-etnia” às “jurídicas”, “económicas”, “religiosas” ou “técnicas” através de algoritmos. Assim, é fundamental produzir uma perspectiva teórico-analítica na sociologia que dê conta destas controvérsias. Isto requer uma perspective geral, abstrata e incisiva, evitando fragmentações teóricas do Sul e do Norte. Para isso, é apresentada uma primeira definição do conceito de “poderes reclassificatórios”. Depois, concentra-se em suas divisões e capacidades para abordar as relações entre poder e dominação, em particular com alguns exemplos da sociologia argentina. Finalmente, são mencionados alguns elementos de continuidade da proposta.; This article presents a proposal for a sociological theory based on reclassificatory powers. Today continuous disputes are unfolding over ways of dividing, qualifying, and hierarchizing the social and natural world. These are the forms of reclassifying with their practical implications—collective and personal—such as inequalities, discriminations, regulations, innovations, etc. Those disputes range from "gender," "class," and "racial-ethnic" recategorizations to "legal," "economic," "religious," or "technical" ones, via algorithms. Thus, it is key to elaborate a theoretical-analytical perspective in sociology that accounts for these controversies. This requires an overall, abstract, and incisive perspective, avoiding theoretical fragmentations of the South and the North. So, a first definition of the concept of "reclassificatory powers" is given. Then, the article focuses on its divisions and capacities to address the relations between power and domination, particularly with some examples from Argentinean sociology. Finally, certain elements of continuity of the proposal are mentioned.

Scatter Search Algorithm for a Waste Collection Problem in an Argentine Case Study Rossit, Diego Gabriel; González, Begoña; Frutos, Mariano; Méndez Babey, Máximo Increasing urbanization and rising consumption rates are putting pressure on urban systemsto efficiently manage Municipal Solid Waste (MSW). Waste collection, in particular, is one of the mostchallenging aspects of MSW management. Therefore, developing computer-aided tools to supportdecision-makers is crucial. In this paper, a Scatter Search algorithm is proposed to address the wastecollection problem. The literature is relatively scarce in applying this algorithm, which has proven tobe efficient in other routing problems, to real waste management problems. Results from real-worldinstances of an Argentine city demonstrate that the algorithm is competitive, obtaining, in the caseof small instances, the same outcomes as those of an exact solver enhanced by valid inequalities,although requiring more computational time (as expected), and significantly improving the results ofthe latter for the case of larger instances, now requiring much less computational time. Thus, ScatterSearch proves to be a competitive algorithm for addressing waste collection problems.

El artesano de los nombres: La presencia del Crátilo de Platón en el Idiota. De mente de Nicolás de Cusa a propósito de la imposición de nombres; The craftsman of names: the presence of Plato's Cratylus in the Nicholas of Cusa’s Idiota - De mente on the impositionof Name Gonzalez Rios, Hector Jose Nicolás de Cusa (1401-1464), cuyo pensamiento florece en los umbrales de la Modernidad, se sabe explícitamente heredero de una plural tradición platónica. Con todo, resulta decisiva la presencia de los diálogos de Platón con los que el Cusano tuvo contacto, sea por vía directa o bien indirecta. El propósito de este artículo es estudiar uno de los tópicos centrales de la concepción cusana del lenguaje, esto es, la imposición de nombres a las cosas, a la luz del tratamiento que ofrece en el tercero de los Idiotaelibri, el De mente (1450), y evaluar allí la presencia plausible del Crátilo de Platón en su desarrollo. Con ello buscamos ofrecer una clave hermenéutica aún no suficientemente explorada en el ámbito internacional de los estudios sobre el pensamiento de Nicolás de Cusa.; Nicholas of Cusa (1401-1464), whose thought unfolds on the threshold of Modernity, is explicitly known to be the heir of a plural Platonic tradition. The presence of Plato's dialogues with which Nicholas of Cusa had contact, either directly orindirectly, is decisive. The purpose of this article is to study one of the central topics of Cusan's conception of language, that is, the naming of things, in the light of its treatment in the third of the Idiotae libri, the De mente (1450), and to evaluate the plausible presence of Plato's Cratylus in its development. Our aimis to offer a perspective that has not been sufficiently explored in the international sphere of Cusan studies.

Finitud y precariedad: entre el fin de la historia y el cristal del tiempo; Finitude and Precariousness: Between the End of History and the Crystals of Time Ferreyra, Diego Julián La hipótesis de este artículo es que estamos ante un desplazamientode la episteme -concepto que Michel Foucault forjó en Las palabras y las cosas-,y la finitud (que fue parte del plexo de sentido que reinó en Europa occidental a partirdel siglo XIX, y que determinaremos puntualmente a partir de la dialéctica de lo finito de G. W. F. Hegel) no da cuenta yadel “ser bruto del orden”. Para pensar la nueva episteme,que Foucault apenas esbozó, postularemos (con recursos conceptuales de Gilles Deleuze, especialmente las de “cristal detiempo” y “devenir”) la noción de precariedad, donde nuestro frágil ser no deja de vincularse con las fuerzas abismales que a cada instante lo engendran y amenazan con destruirlo.; The hypothesis of this paper is that we are facing a shift of the episteme ―a concept constructed by Michel Foucault in The order of things―, and that therefore finitude (which was part of the web of sense that reigned in Western Europe since the early XIX Century, and that we will determine through Hegel’s dialectic of the finitude) no longer accounts for “order in its primary state”. In order tho conceive the new episteme, which Foucault merely sketched, we will posit (with conceptual resources taken from Gilles Deleuze, notably the “crystal of time”) the notion of precariousness, where our fragile being bonds itself endlessly with abyssal forces that at each instant engender it and menace with its destruction.

Difference in reproductive traits of two sympatric species of Stigmaphyllon (Malpighiaceae) throughout their distribution range: Are they context-dependent? Avalos, Adan Alberto; Ferrucci, María Silvia; Torretta, Juan Pablo Populations of widely distributed plants may experience varying climatic or ecological conditions, leading to uneven evolution of reproductive traits. However, studies on reproductive biology usually focus on just one, or rarely two, sampling areas. In this study, we performed a geographical comparative analysis of the flowering pattern, pollination biology and breeding system of Stigmaphyllon bonariense and S. jatrophifolium (Malpighiaceae) throughout their natural distribution in Argentina, classifying them as ‘northern’ or ‘southern’ according to their geographic location. For this, we selected 4 populations for S. bonariense and 3 for S. jatrophifolium to characterized the flowering peak at both the individual (IFP) and population (PFP) levels, the floral display per inflorescence, the richness of Malpighiaceae species and their pollinators, and the stigmatic and body pollen loads of the pollinators. In addition, we performed manipulative experiments to determine the breeding system. Our results showed that the duration of flowering phenology and the floral display vary between northern and southern populations of both species. These traits include flowering duration and the number of flowers at anthesis per inflorescence (floral display). In addition, the pollination context exhibited latitudinal differences in species richness, phenology, body size of oil-collecting bees, and visitation frequency. Besides, the number of co-flowering Malpighiaceae species varied among populations. However, no considerable differences were observed among populations in terms of stigmatic and body pollen load in pollinators of both species. The breeding system was invariable and consistent in both species with self-incompatibility (SI). These findings suggest that certain reproductive traits of both Stigmaphyllon species are context-dependent and would allow the species maximise reproductive success in each population. Therefore, our results demonstrate that large-scale geographical studies (i.e., several populations with different climatic conditions) and the analysis of various phenological traits are necessary to better understand the reproductive biology of plant species.

Consecuencias negativas de la organización androcéntrica de la política en varones parlamentarios de provincias con extensa trayectoria en leyes de paridad de género: El caso de Córdoba, Argentina; Negative consequences of the androcentric organization of politics in male parliamentarians from provinces with an extensive history of gender parity laws: The case of Córdoba, Argentina Francovich, Mila; Saletti, Lorena; Brussino, Silvina Alejandra El objetivo de la presente investigación fue explorar, desde la perspectiva de los parlamentarios varones, la existencia de cambios en la organización androcéntrica de la política en sistemas representativos con una larga trayectoria en la implementación de leyes de paridad de género, utilizando como caso de estudio la provincia de Córdoba (Argentina). Se llevaron a cabo 12 entrevistas con legisladores de diferentes partidos y se realizó un análisis temático con el software Atlas.ti. Los hallazgos indicaron que en sistemas políticos atravesados por leyes de paridad de género, existen variaciones en las experiencias masculinas en relación con la persistente organización androcéntrica de la política. Sin embargo, también se constató que, a pesar de identificar los efectos perjudiciales de dicha organización en sus vidas, los varones no modifican su comportamiento. Estos resultados sugieren que, aunque las leyes de paridad de género han facilitado avances significativos en la representación de mujeres en la esfera política institucional, no han logrado transformar la estructura organizacional diseñada para favorecer a los varones y perpetuar la desigualdad de género. Entre las limitaciones de este estudio se destaca su incapacidad para ser exhaustivo en la identificación y análisis de otras consecuencias negativas de la organización androcéntrica de la política que los parlamentarios varones puedan reconocer, así como en la comprensión de la variabilidad de la experiencia masculina frente a dicha organización tras la implementación de la ley de paridad de género.; The aim of this research was to explore, from the perspective of male parliamentarians, the existence of changes in the androcentric organization of politics in representative systems with a long history of implementing gender parity laws, using the province of Córdoba (Argentina) as a case study. Twelve interviews were conducted with legislators from different parties, and thematic analysis was performed using Atlas.ti software. The findings indicated that in political systems influenced by gender parity laws, there are variations in male experiences concerning the persistent androcentric organization of politics. However, it was also found that, despite identifying the detrimental effects of this organization in their lives, men do not change their behavior. These results suggest that although gender parity laws have facilitated significant advances in the representation of women in the institutional political sphere, they have not managed to transform the organizational structure designed to favor men and perpetuate gender inequality. Among the limitations of this study is its inability to be exhaustive in identifying and analyzing other negative consequences of the androcentric organization of politics that male parliamentarians may recognize, as well as in understanding the variability of male experiences in relation to this organization following the implementation of gender parity laws.

Lucrecia Martel, escribidora de cartas; Lucrecia Martel, letter writer; Lucrecia Martel, écrivaine prolifique de lettres Kratje, Julia En el cine de Lucrecia Martel, la literatura recibe un tratamiento acústico antes que visual, mientras que en sus cartas aparecen reverberaciones que provienen tanto del cine como de la literatura para abrirse paso como una cineasta implicada en el presente. Si la escritura cristaliza la palabra hablada y la imprenta termina de incrustarla en el espacio visual, tanto las películas como los discursos públicos de Martel, manifiestos en el género epistolar por excelencia, toman el camino inverso: las palabras no son arrancadas del arco sonoro, donde tuvieron su origen en el intercambio humano activo, para relegarlas al orden visual.; Dans le cinéma de Lucrecia Martel, la littérature reçoit un traitement acoustique plutôt que visuel, tandis que dans ses lettres apparaissent des réverbérations venues à la fois du cinéma et de la littérature pour se frayer un chemin en tant que cinéaste impliquée dans le présent. Si l’écriture cristallise la parole et que l’imprimerie finit de l’incruster dans l’espace visuel, les films de Martel comme les discours publics, manifestes dans le genre épistolaire par excellence, prennent le chemin inverse : les mots ne sont pas arrachés à l’arc sonore, où ils ont leur origine dans un échange humain actif, pour les reléguer à l’ordre visuel.; In Lucrecia Martel’s cinema, literature receives an acoustic treatment rather than a visual one, while in her letters reverberations appear to come from both cinema and literature to make her way as a filmmaker involved in the present. If writing crystallizes the spoken word and the printed press finishes embedding it in the visual space, both Martel’s films and public speeches, manifested in the epistolary genre par excellence, take the opposite path: the words are not torn from the sound sphere, where they had their origin in active human exchange, to relegate them to the visual order.

La Eucaristía en el Libro I del Pedagogo de Clemente de Alejandría; The Eucharist in Book I of the Pedagogue of Clement of Alexandria Druille, Paola Ivone El objetivo de nuestro estudio es analizar el pensamiento eucarístico presente en el Libro I del Pedagogo de Clemente de Alejandría a partir de tres problemáticas. En primer lugar, examinaremos los simbolismos proféticos arraigados en prefiguraciones del Antiguo Testamento, las cuales actúan como anticipaciones de la Eucaristía en el Nuevo Testamento. En segundo lugar, nos adentraremos en la noción de la Eucaristía como alimento espiritual, mostrando la conexión intrínseca entre la naturaleza divina, la humanidad encarnada de Cristo y el pneûma como el medio para el acceso al conocimiento de verdades teológicas. Por último, exploraremos interpretaciones adicionales relacionadas con las dos problemáticas anteriores. Estas interpretaciones buscan recuperar referencias de simbolismos anticipatorios y espirituales mediante un análisis de referencias bíblicas significativas.; The aim of our paper is to study the Eucharistic thought present in Book I of the Pedagogue of Clement of Alexandria based on three problems. First, we will examine the prophetic symbolism rooted in Old Testament prefigurations, whichact as anticipations of the Eucharist in the New Testament. Secondly, we will delvein to the notion of the Eucharist as spiritual food, showing the intrinsic connection between the divine nature, the incarnate humanity of Christ and the pneûma as the means to access the knowledge of theologicaltruths. Finally, wewill explore additional interpretations related to the two previous problems. These interpretations seek to recover references of anticipatory and spiritual symbolism through a careful analysis of significant biblical references.

Producción de textos argumentativos en educación secundaria de acuerdo con el desempeño en comprensión: una aproximación psicolingüística; Writing of argumentative texts in secondary education according to performance in reading comprehension: a psycholinguistic approach Chimenti, María de Los Ángeles; Abusamra, Valeria La lectura y la escritura son habilidades lingüísticas culturales fundamentales para el éxito académico. Si bien producir un texto es una actividad cognitivamente más costosa que comprenderlo, ambas actividades comparten componentes lingüísticos y cognitivos subyacentes. El objetivo de este trabajo es determinar si existen diferencias en las características de los textos argumentativos producidos por estudiantes de escuela secundaria de acuerdo con su desempeño en comprensión. Para ello, se evaluó a 59 estudiantes argentinos con una prueba de comprensión y otra de producción de textos argumentativos. Sobre la base de la primera, se identificó un subgrupo de alto y otro de bajo desempeño en comprensión. Mientras que el subgrupo de bajo desempeño en comprensión escribió sin considerar los aspectos retóricos involucrados en la consigna, el subgrupo de alto desempeño en comprensión produjo textos argumentativos que resultaron, en general, más adecuados y de mayor calidad. Estos hallazgos constituyen un aporte al estudio de los vínculos entre comprensión y producción de textos, un área insuficientemente desarrollada en la investigación en español. Además, pueden contribuir a la formulación de estrategias de enseñanza, en particular para estudiantes de escuela secundaria con dificultades.; Reading and writing are fundamental cultural language skills crucial for academic success. Although writing a text is cognitively more demanding than reading, both activities share underlying linguistic and cognitive components. This paper aims to determine whether differences exist in the characteristics of argumentative texts produced by secondary school students based on their reading comprehension performance. To this end, 59 Argentinean students were evaluated using a comprehension test and an argumentative text production test. Based on the comprehension test results, subgroups of high and low comprehension performance were identified. The low comprehension subgroup produced texts without considering the rhetorical aspects of the task, while the high comprehension subgroup wrote more adequate and higher quality argumentative texts. These findings contribute to the study of the relationship between comprehension and text production, an area insufficiently developed in Spanish research. Additionally, they may inform the development of teaching strategies, particularly for secondary school students facing difficulties.

El rol de los agentes del campo cultural en la custodia y producción de colecciones arqueológicas del Área de Ventania (provincia de Buenos Aires, Argentina); The role of agents in the cultural field in the custody and production of archaeological collections in the Ventania Area (Buenos Aires province, Argentina) Oliva, Camila Este trabajo investiga el impacto del coleccionismo arqueológico en el sudoeste de la provincia de Buenos Aires, Argentina, específicamente en los municipios de Tornquist, Saavedra y Puan, ubicados en el área arqueológica de Ventania. La investigación analiza cómo los coleccionistas e investigadores aficionados han influido en la creación y desarrollo de museos locales, así como en la preservación del patrimonio arqueológico de comunidades cazadoras-recolectoras del Holoceno medio. La metodología incluyó estudios biográficos, entrevistas en profundidad con coleccionistas y aficionados, relevamiento de exposiciones museísticas y análisis de redes para entender las conexiones entre actores e instituciones.

Imágenes tergiversadas: Plataformas digitales y colectivos artísticos erráticos; Distorted images: Digital platforms and erratic art collectives Martinelli, Lucas Sebastián El objetivo de este artículo es reflexionar sobre los modos en los que en el campo de experimentación estético produce la posibilidad de impugnar los usos de los dispositivos tecnológicos y las nuevas formas de subjetividad vinculadas con las interacciones en las plataformas, para observar la posibilidad de subversión en las mismas. Las imágenes tergiversadas refieren al marco visual de las plataformas que aparecen en el arte como una forma de apelar al malestar de lo digital. Por eso este artículo comienza con un panorama del uso de los datos y las maneras contemporáneas de entender la relación entre las plataformas, las imágenes y los archivos digitales; para luego centrarse en cada uno de los casos a analizar. El video experimental y las prácticas del colectivo Suavecitxs Arf, la obra de danza Coreografías de la vergüenza con sus paratextos y la película El auge de lo humano 3 son tres propuestas artísticas muy distintas que tienen en común los rasgos de disconformidad con el mundo digital en el que cohabitan. A su vez, se trata de objetos paralelos a un conjunto de prácticas de intercambio entre colectivos artísticos que están en tránsito constante entre el mundo material y virtual.; The objective of this article is to reflect on the ways in which the field of aesthetic experimentation produces the possibility of contesting the uses of technological devices and the new forms of subjectivity linked to interactions on platforms, to observe the possibility of subversion. The distorted images refer to the visual framework of the platforms that appear in art as a way of appealing to the discomfort about the digital. That is why this article begins with an overview of the use of data and contemporary ways of understanding the relationship between platforms, images and digital files; and then focus on each of the cases to be analyzed. The experimental video and practices of the Suavecitxs Arf collective, the dance work Coreografías de la vergüenza with its paratexts and the film The Rise of the Human 3 are three very different artistic proposals that have in common the traits of disagreement with the digital world in the one they cohabit. At the same time, these are objects parallel to a set of exchange practices between artistic collectives that are in constant transit between the material and virtual world.
