A Latitudinal Cline in the Taxonomic Structure of Eelgrass Epifaunal Communities is Associated With Plant Genetic Diversity Gross, Collin P.; Duffy, J. Emmett; Hovel, Kevin A.; Reynolds, Pamela L.; Boström, Christoffer; Boyer, Katharyn E.; Cusson, Mathieu; Eklöf, Johan; Engelen, Aschwin H.; Eriksson, Britas Klemens; Fodrie, F. Joel; Griffin, John N.; Hereu, Clara María; Hori, Masakazu; Hughes, A. Randall; Ivanov, Mikhail V.; Jorgensen, Pablo; Kardish, Melissa R.; Kruschel, Claudia; Lee, Kun Seop; Lefcheck, Jonathan; McGlathery, Karen; Moksnes, Per Olav; Nakaoka, Masahiro; O'Connor, Mary I.; O'Connor, Nessa E.; Olsen, Jeanine L.; Orth, Robert J.; Peterson, Bradley J.; Reiss, Henning; Rossi, Francesca; Ruesnik, Jennifer; Sotka, Erik E.; Thormar, Jonas; Tomas, Fiona; Unsworth, Richard; Voigt, Erin P.; Whalen, Matthew A.; Ziegler, Shelby L.; Stachowicz, John J. Aim Biogenic structural complexity increases mobile animal richness and abundance at local, regional and global scales, yet animal taxa vary in their response to complexity. When these taxa also vary functionally, habitat structures favouring certain taxa may have consequences for ecosystem function. We characterised global patterns of epifaunal invertebrates in eelgrass (Zostera marina) beds that varied in structural and genetic composition. Location North America, Europe and Asia. Time Period 2014. Major Taxa Studied Peracarid crustaceans and gastropod molluscs. Methods We sampled epifaunal invertebrate communities in 49 eelgrass beds across 37° latitude in two ocean basins concurrently with measurements of eelgrass genetic diversity, structural complexity and other abiotic and biotic environmental variables. We examined how species richness, abundance and community composition varied with latitude and environmental predictors using a random forest approach. We also examined how functional trait composition varied along with community structure. Results Total species richness decreased with latitude, but this was accompanied by a taxonomic shift in dominance from peracarid crustaceans to gastropods, which exhibited different sets of functional traits. Greater eelgrass genetic diversity was strongly correlated with both richness and abundance of peracarids, but less so for gastropods. Main Conclusions Our results add to a growing body of literature that suggests genetic variation in plant traits influences their associated faunal assemblages via habitat structure. Because peracarids and gastropods exhibited distinct functional traits, our results suggest a tentative indirect link between broad-scale variation in plant genetic diversity and ecosystem function.

Learning with computer simulations: A case study on reservoir temperatures in carnot cycles; Aprendizagem com Simulações Computacionais: Um estudo de caso sobre temperaturas de reservatório em ciclos de Carnot Velasco, Juan José; Buteler, Laura Maria; Coleoni, Enrique Andres Computer simulations have played a significant role in the development of physics, and in physics education as well. Researchers have addressed whether simulations promote learning, but few studies have investigated how simulations actually participate in learning processes. This study seeks to describe how simulations participate in conceptual learning. A case study is carried out using videotaped interviews with three groups of undergraduate students as they address a problem-solving task on thermodynamics (Carnot cycles). Students use a specifically developed simulation for support. The analysis is based on Coordination Class Theory (CCT). Results indicate that students not only use the simulation to think; it is actually a part of what they think. Students were found to engage in three different interaction dynamics with the simulation. Attuned with CCT, these were coded as either Extractive/Inferential/Articulative interactions. In each case, the substance of how these interactions input conceptual learning is described. Implications for future research and for teaching are given.; As simulações computacionais desempenharam um papel significativo no desenvolvimento da física e também na educação em física. Pesquisadores têm se perguntado se as simulações promovem a aprendizagem, mas poucos estudos investigaram como as simulações realmente participam dos processos de aprendizagem. Este estudo busca descrever como as simulações participam da aprendizagem conceitual. Foi realizado um estudo de caso utilizando entrevistas gravadas em vídeo com três grupos de estudantes de graduação enquanto eles resolvem uma tarefa sobre termodinâmica (ciclos de Carnot). Os estudantes utilizam uma simulação especificamente desenvolvida para dar suporte à tarefa. A análise é baseada na Teoria das Classes de Coordenação (TCC). Os resultados indicam que os estudantes não apenas utilizam a simulação para pensar; ela é, na verdade, parte do que eles pensam. Foi observado que os estudantes se engajam em três dinâmicas diferentes de interação com a simulação. De acordo com a TCC, essas interações foram codificadas como interações Extrativa/Inferencial/Articulada. Em cada caso, descreve-se como a substância dessas interações contribui para a aprendizagem conceitual. São apresentadas implicações para futuras pesquisas e para o ensino.

Assessing traditional and machine learning methods to smooth and impute device-based body condition score throughout the lactation in dairy cows Chelotti, Jose Omar; Atashi, H.; Ferrero, Mariano; Grelet, C.; Soyeurt, H.; Giovanini, Leonardo Luis; Rufiner, Hugo Leonardo; Gengler, N. Regular monitoring of body condition score (BCS) changes during lactation is an essential management tool in dairy cattle; however, the current BCS measurements are often discontinuous and unevenly spaced in time. The imputation of BCS values is useful for two main reasons: i) achieving completeness of data is necessary to be able to relate BCS to other traits (e.g. milk yield and milk composition) that have been routinely recorded at different times and with a different frequency, and ii) having expected BCS values provides the possibility to trigger early warnings for animals with certain unexpected conditions. The contribution of this study was to propose and evaluate potential methods useful to smooth and impute device-based BCS values recorded during lactation in dairy cattle. In total, 26,207 BCS records were collected from 3,038 cows (9,199 and 14,462 BCS records on 1,546 Holstein and 1,211 Montbéliarde cows respectively, and the rest corresponded to other minority cattle breeds). Six methods were evaluated to predict BCS values: the traditional methods of test interval method (TIM), and multiple-trait procedure (MTP), and the machine learning (ML) methods of multi-layer perceptron (MLP), Elman network (Elman), long-short term memories (LSTM) and bi-directional LSTM (BiLSTM). The performance of each method was evaluated by a hold-out validation approach using statistics of the root mean squared error (RMSE) and Pearson correlation (r). TIM, MTP, MLP, and BiLSTM were assessed for the imputation of intermediate missing values, while MTP, Elman, and LSTM were evaluated for the forecasting of future BCS values. Regarding the machine learning methods, BiLSTM demonstrated the best performance for the intermediate value imputation task (RMSE = 0.295, r = 0.845), while LSTM demonstrated the best performance for the future value forecasting task (RMSE = 0.356, r = 0.751). Among the methods evaluated, MTP showed the best performance for imputation of intermediate missing values in terms of RMSE (0.288) and r (0.856). MTP also achieved the best performance for forecasting of future BCS values in terms of RMSE (0.348) and r (0.760). This study demonstrates the ability of MTP and machine learning methods to impute missing BCS data and provides a cost-effective solution for the application area.

Osteology, relationship, and feeding ecology of the theropod dinosaur Noasaurus leali Bonaparte and Powell, 1980, from the Late Cretaceous of North-Western Argentina Hendrickx, Christophe Marie Fabian; Cerroni, Mauricio Andrés; Agnolin, Federico; Catalano, Santiago Andres; Ribeiro, Cátia F.; Delcourt, Rafael Noasaurus leali is a small (~2 m) carnivorous theropod and the nominal genus of the clade Noasauridae, one of the two radiations of abelisauroid ceratosaurs predominantly present in the Southern Hemisphere during the Mesozoic. This eponymous theropod from the Maastrichtian Lecho Formation of Salta, Argentina, is known from an incomplete skeleton of which the strongly curved manual ungual is the most peculiar element. We here provide for the first time a comprehensive description of the holotypic specimens of Noasaurus, whose phylogenetic position was explored using three independent datamatrices on theropod relationships. This species is diagnosed by several apomorphies such as a dorsal ridge in the maxillary fossa, a strongly arched quadrate, a cervical neural arch with anterior epipophyseal prongs, and a manual ungual with a subtriangular flexor fossa delimited by a V-shaped ridge. Results of the phylogenetic analyses recovered Noasaurus closely related to Velocisaurus, Masiakasaurus, and Laevisuchus, which together form a Late Cretaceous radiation of small-bodied noasaurids restricted to the Southern Hemisphere. The peculiar morphology of the lateral dentition and manual unguals suggests that Noasaurus was an opportunistic carnivore feeding on small prey items and a possible piscivore gaffing fish with its specialized hand claws.

Disidentes en el exilio: Montoneros 17 de Octubre y los desplazamientos de la subjetividad revolucionaria armada en el cambio de década Slipak, Daniela Verónica Con herramientas historiográficas y teórico-políticas, este artículo se centra en la confor­mación del último grupo disidente de la organización político-militar argentina Monto­neros, Montoneros 17 de Octubre. Se reconstruyen su surgimiento, sus redes y sus debates, interrogando las transformaciones de la subjetividad revolucionaria armada que se suce­dieron en el exilio. Para ello, se utilizan documentos internos, comunicados, órganos de prensa y testimonios orales y escritos. ¿Qué significados sobre la violencia sostuvieron? ¿Qué idea de revolución defendieron? ¿Cómo se hibridaron estos elementos propios de la militancia de los setenta con la noción de democracia y de derechos humanos que circu­ló a inicios de los ochenta? A través de estas preguntas, el artículo pretende: a) aportar al estudio de las discusiones internas y de la cultura normativa de los grupos armados de la nueva izquierda latinoamericana de los años sesenta y setenta; b) contribuir al examen de las redes transnacionales que atravesaron y sostuvieron esos grupos; c) analizar las expe­riencias exiliares originadas a raíz de la represión de las dictaduras instauradas en el Cono Sur; y d) comprender los desplazamientos de la subjetividad revolucionaria a fines de los setenta y comienzos de los ochenta.; By means of historiographical and theoretical-political tools, this article focuses on the formation of the last dissident group of the Argentinian political-military organization Montoneros, Montoneros 17 de Octubre. Its emergence, networks and debates are reconstructed questioning the transformations of the armed revolutionary subjectivity that took place in exile. For this purpose, internal documents, statements, press organs and oral and written testimonies are used. Which meanings about violence did they hold? What idea of revolution did they defend? How were these elements of militancy of the seventies hybridized with the notion of democracy and human rights that circulated at the beginning of the eighties? Through these questions, the article aims to: a) contribute to the study of the internal discussions and the normative culture of the armed groups of the new Latin American left in the 1960s and 1970s; b) contribute to the examination of the transnational networks that crossed and sustained these groups; c) contribute to the analysis of the exile experiences resulting from the repression of the dictatorships established in the Southern Cone; and d) contribute to the understanding of the displacement of revolutionary subjectivity at the end of the 1970s and the beginning of the 1980s.

Teorías del Estado en clave latinoamericana: Itinerarios conceptuales y lecturas situadas; Theories of the State from a Latin American perspective: Conceptual itineraries and contextual readings Ouviña, Hernan Dario El objetivo del artículo es reponer y analizar algunas lecturas y conceptualizaciones críticas del Estado, que se han planteado desde la propia realidad latinoamericana, para comprender de forma más compleja e integral los rasgos específicos y también aquellas características generales que supone la estatalidad en nuestro continente. Ello supone asumir que el Estado constituye una instancia clave de condensación del poder político y de las relaciones de fuerzas que configuran y desgarran a la propia sociedad de la que, a su vez, forma parte. Consideramos que, si bien el marxismo europeo clásico brinda valiosos aportes para entender al Estado, es preciso complementar las hipótesis y conjeturas que han sido formuladas en otras latitudes, con aquellas gestadas en la región. Por lo tanto, pasaremos revista a algunas de las principales interpretaciones del Estado esbozadas desde y para América Latina dentro de la tradición neomarxista, las teorías feministas y por parte de ciertos exponentes del pensamiento crítico anticolonial gestado en nuestro continente, que más allá de sus matices y posibles contrastes, coinciden en la necesidad de aportar a una epistemología específica y situada, aunque sin desestimar las determinaciones y límites que impone el sistema-mundo con su configuración desigual y asimétrica.; The objective of the article is to review and analyze some critical readings and conceptualizations of the State, which have been raised from the Latin American reality itself, to understand in a more complex and comprehensive way the specific features and also those general characteristics that statehood entails on our continent. This means assuming that the State constitutes a key instance of condensation of political power and the relations of forces that shape and tear apart the very society of which, in turn, it is a part. We consider that, although classical european marxism provides valuable contributions to understanding the State, it is necessary to complement the hypotheses and conjectures that have been formulated in other latitudes, with those developed in the region. Therefore, we will review some of the main interpretations of the State outlined from and for Latin America within the neo-marxist tradition, feminist theories and by certain exponents of anticolonial critical thought developed on our continent, which beyond its nuances and possible contrasts, agree on the need to contribute to a specific and situated epistemology, although without dismissing the determinations and limits imposed by the worldsystem with its unequal and asymmetric configuration.

Saica Amyot and Serville (Reduviidae, Emesinae, Saicini): taxonomic revision and phylogenetic analysis with morphological characters Castro Huertas, Ana Valentina; Melo, María Cecilia The Neotropical assassin bug genus Saica Amyot & Serville, 1843 (Reduviidae Latreille, 1807, Emesinae Amyot & Serville, 1843, Saicini Stål, 1859) includes thirteen valid species, nevertheless itsbiology and natural history is almost unknown. A taxonomic revision and a morphological phylogenetic analysis were carried out to test the species limits and to propose a hypothesis of evolutionary relationships. Saica is characterized by the tufts of strong setae on the mandibular plates and on the postocular region; the short pedicellus; the produced anterior margin of the proepisternal supracoxal lobe; the simple strong setae on the prolegs; the bifid posteromedial process of pygophore; and the vertical to subvertical posterior margin of the abdominal sternite VII in females. After this study, we propose fourteen valid species: Saica apicalis Osborn & Drake, 1915, S. carayoni Villiers, 1943, S. cruentata Bergroth, 1913, S. elkinsi Blinn, 1994, S. erubescens Champion, 1898, S. fuscipes Stål, 1862, S. lativentris Villiers, 1943, S. meridionalis Fracker & Bruner, 1924, S. ochracea Distant, 1902, S. recurvata (Fabricius, 1803), S. rubripes Champion, 1898, S. subinermis Hussey, 1953, S. tibialis Stål, 1862, and S. tupackatari n. sp. from Bolivia. The phylogenetic analyses recovered Saica as a monophyletic group with the following set of relationships: ((S. ochracea + S. tupackatari n. sp.) (S. carayoni (S. recurvata (S. rubripes ((S. subinermis (S. apicalis + S. meridionalis)) (S. elkinsi (S. erubescens (S. lativentris + S. tibialis)))))))).

Metáforas de la(s) revuelta(s) en la narrativa chilena reciente; Metaphors of the Revolts in the Recent Chilean Narrative Cabrera, Mario Federico David Este artículo se propone analizar cómo se han representado las revueltas populares chilenas de los últimos años en un corpus de narrativa reciente desde una perspectiva teórica y metodológica que atiende a los cruces entre prácticas literarias y discursos sociales. En líneas generales, el corpus está integrado por un conjunto de novelas que, desde propuestas estéticas diferentes, articulan una serie de metáforas que aluden a una crisis generalizada del modelo político y económico predominante e inscriben en el presente la memoria de los crímenes cometidos por la dictadura militar: Avenida 10 de Julio (2022) de Nona Fernández, Sumar (2018) de Diamela Eltit, Satancumbia (2020) de Rodrigo Miranda y La orquesta imaginaria (2021) de Rodrigo Díaz Cortez. De acuerdo con lo señalado, el análisis focaliza en las operaciones discursivas a través de las que se hace referencia a la violencia ejercida por el Estado y al rol de las prácticas artísticas en contextos represivos.; This article analyzes how the Chilean social uprisings of recent years have been represented in a corpus of recent narrative from a theoretical and methodological perspective that attends to the intersections between literary practices and social discourses. In general terms, the corpus is made up of a set of novels that, from different aesthetic proposals, articulate a series of metaphors that allude to a generalized crisis of the predominant political and economic model and inscribe in the present the memory of the crimes committed by the military dictatorship: Avenida 10 de Julio (2022) by Nona Fernández, Sumar (2018) by Diamela Eltit, Satancumbia (2020) by Rodrigo Miranda and La orquesta imaginaria (2021) by Rodrigo Díaz Cortez. In accordance with what was previously indicated, the analysis focuses on the discursive operations through which reference is made to the violence exerted by the State and the role of artistic practices in repressive contexts.

La concepción ampliada del capitalismo de Nancy Fraser: Reflexiones sobre su conceptualización y periodización Gluj, Anabella En el presente artículo, analizamos la teoría ampliada del capitalismo de Nancy Fraser en sus últimos tres libros publicados en español: ¡Contrahegemonía ya! Por un populismo progresista que enfrente al neoliberalismo (2019), Los talleres ocultos del capital. Un mapa para la izquierda (2020) y Capitalismo caníbal: qué hacer con este sistema que devora la democracia y el planeta, y hasta pone en peligro su propia existencia (2023). A lo largo de este trabajo, ahondamos en el diálogo de estas tres obras en pos de comprender el recorrido teórico de Fraser en los últimos años respecto a su conceptualización del capitalismo.El análisis crítico de los planteos de Fraser lo focalizamos en dos ejes. En primer lugar, examinamos su concepción del capitalismo, sus alcances y límites. Luego, abordamos la periodización del capitalismo que propone, atendiendo a los criterios subyacentes para delimitar cada una de las etapas y el modo en que éstas son concebidas. Acotamos el análisis a estas cuestiones sólo como punto de partida para profundizar en otros ejes que se desprenden de su obra en futuras aproximaciones.

Cromosomas y hormonas ¿sexuales?: Enredos de cultura y biología en el estudio científico de la diferencia sexual; Sex? chromosomes and hormones: Entanglements of culture and biology in the scientific study of sexual difference Solana, Mariela Este trabajo explora el intercambio de ideas entre la cultura y las ciencias naturales en la búsqueda de una explicación biológica de la diferencia sexual. Los dos elementos que serán analizados aquí son los llamados cromosomas sexuales y hormonas sexuales. Para eso, paso revista a una serie de análisis históricos sobre la biología de la diferencia sexual de principio de siglo XX en EEUU. El objetivo principal del trabajo es demostrar que la historia de la sexualización de las hormonas y los cromosomas da cuenta del entrelazamiento entre sexo y género, es decir, entre cómo se caracteriza el cuerpo sexuado y cómo se concibe culturalmente la masculinidad y feminidad. El segundo objetivo es usar este entrelazamiento como un argumento a favor de una lectura no determinista de la relación entre ciencia y sociedad y de una lectura no antagónica de la relación entre ciencia y feminismo.; This paper explores the exchange of ideas between culture and natural sciences when sexual differences are explained at the biological level. The two elements that I shall analyze here are the so called sex chromosomes and sex hormones. I review a series of historical accounts on the biology of sexual difference from the beginning of the 20th century in the US. My first goal is to demonstrate that the history of the sexualization of these two elements allows us to see the intertwining between sex and gender, that is, between how we think about the sexed body and social beliefs about masculinity and femininity. The second goal is to use this intertwining as an argument in favor of a non-deterministic account of the relationship between science and society and of a non antagonist account of the relationship between science and feminism.

Epistemes feministas en la genealogía historiográfica de Joan W. Scott: Una crítica sobre sus políticas narrativas contemporáneas Videla, Hernán Isidro Joan Wallach Scott, destacada historiadora norteamericana, ha influido significativamente en la historiografía y el feminismo contemporáneo. Criada en un entorno familiar afectado por la persecución macartista, Scott fue moldeada por el activismo de sus padres y su propio compromiso con el feminismo. Se destacó por su análisis crítico de la historiografía neomarxista. En la década de 1980 y 1990, Scott adoptó un enfoque postestructuralista, cuestionando nociones de identidad universal y proponiendo un análisis histórico del género como una construcción dinámica y culturalmente condicionada. Su obra más reciente explora la intersección del género con los derechos humanos, las dimensiones de raza y clase, y las políticas de paridad, en el marco de una crítica poscolonial a las categorías binarias del mundo occidental acuñadas durante la modernidad. Scott sigue siendo una figura clave en la academia contemporánea, con un enfoque que desafía las narrativas tradicionales y promueve una comprensión más historizada del género.; Joan Wallach Scott, a prominent American historian, has significantly influenced contemporary historiography and feminism. Raised in a family environment affected by McCarthyist persecution, Scott was shaped by her parents' activism and her own commitment to feminism. She is noted for her critical analysis of neo-Marxist historiography. In the 1980s and 1990s, Scott adopted a poststructuralist approach, questioning notions of universal identity and proposing a historical analysis of gender as a dynamic and culturally conditioned construct. Her most recent work explores the intersection of gender with human rights, the dimensions of race and class, and parity politics, within the framework of a postcolonial critique of the binary categories of the Western world coined during modernity. Scott remains a key figure in contemporary academia, with an approach that challenges traditional narratives and promotes a more historicized understanding of gender.

Pappus morphology and heterocarpy in Stevia (Eupatorieae, Asteraceae): A systematic study of cypselae diversity and geographic distribution Rodríguez Cravero, Juan Facundo; Cisterna, Gabriela; Grossi, Mariana Andrea; Gutierrez, Diego Germán The genus Stevia (Asteraceae, Eupatorieae) is widely distributed across the Americas and exhibits remarkable diversity in cypsela morphology and pappus structure. The variation in pappus types, including both homocarpic and heterocarpic species, plays a critical role in species delimitation within the genus. In this study, we investigate the morphology of cypselae and pappus across a diverse sample of Stevia species, emphasizing the systematic significance of pappus variation. Species were analyzed using light and scanning electron microscopy, focusing on key traits such as pappus structure, the presence of heterocarpy, and the arrangement of cypselae within the capitulum. Eight distinct pappus types were identified and described as fundamental morphological patterns. Additionally, species distribution maps are provided to illustrate the geographical patterns associated with these pappus types. Our findings contribute to a deeper understanding of morphological diversity within Stevia and underscore the importance of pappus variation in species identification and taxonomic classification.

El lenguaje claro y el alerta sobre los malos usos de la lengua en el ámbito jurídico; Plain Language and the Alert on Misuses of Speech in Legal Practice Lell, Helga María Este trabajo sostiene que existe un problema respecto de la denominación “lenguaje claro” puesto que no se trata propiamente de lenguaje y que la claridad no es tal sino que es una pretensión. Se explica que, si bien el movimiento pone en el centro de la escena al receptor, esto no se concreta normalmente en la práctica. Por último, se señala por qué estas claves de redacción se aplican tanto al lenguaje técnico como al natural y se argumenta que no se deben legitimar los errores de comunicación al afirmar que son propios del ámbito jurídico y que pueden traducirse con claridad con otro nuevo texto. Así, el lenguaje claro debe reservarse específicamente para adaptar un mensaje a un público en particular, no para aceptar que se haga un mal uso de la lengua bajo el pretexto de que es una forma profesional de redacción.; This paper argues that there is a problem with the concept of plain language since it is not really language and there is only a pretension of at clarity. It is explained that, although the movement puts the receiver at the centre of the scene, this does not usually materialize in practice. Finally, it is pointed out why these drafting keys apply to both technical and natural language and it is argued that errors of communication should not be legitimized by claiming that they are specific to the legal field and that they can be translated more clearly to another new text. Thus, plain language should be reserved specifically for adapting a message to a particular audience, not for accepting misuse of language under the pretext that it is a professional form of drafting.

Montarse (en) un cuerpo Gutierrez, Maria Laura El trabajo se construye desde un collage visual para el dossier Eróticas en fuga, del numero 15 de la Revista Etcétera coordinados por las Dras. Paula Shabel y Andrea Lacombre. Desde las formas en que se construyen las imágenes, las visualidades y aquello que queda fuera de los márgenes de lo visible, el trabajo indaga sobre las fugas visuales que pueden encontrarse en archivos comunes de la infancias.

The transformative relation between publishers and editors: Research quality and academic autonomy at stake Beigel, Maria Fernanda The prevalence of scientific journals amid the expansion of digital platforms and mega-infrastructures features the persistent will of scholars to give part of their time to this endeavor, which is frequently a thankless task and subject to intense pressures. In this paper, we focus on scholarly editorship and the existing commercial interferences to explore whether this has an equal incidence in publishing circuits outside the mainstream. For this purpose, we describe the case of Latin America, where a parallel value system is observed through indexation criteria focused on academic quality and independent editorship. We examined 1,971 Scielo and Redalyc journals stressing the features of editorial teams, publishing institutions, and calibrating the penetration of the APC business model. We argue that the development of this regional publishing circuit, along with the value system that explains its survival, finds its main strength in its public nature and the crucial role of universities’ autonomy, although its main weakness in the absence of an interoperable infrastructure capable of broadening its circulation. Eventually, we discuss the idea of predatory publishing and its evolution from the representation of journal backwardness to fraudulent forprofit publications, proposing to reorient the value of scientific journals onto their academic autonomy.

Variación de la huella hídrica en procesos industriales según el alcance establecido para su cálculo: El caso de una embotelladora, una curtiembre y una cervecera de la provincia de Salta, Argentina; Variation of the water footprint in industrial processes according to the scope established for its calculation: The case of bottled water, leather tanning, and beer production in the province of Salta, Argentina Mainardi Remis, Juan Martín; Gutiérrez Cacciabue, Dolores La huella hídrica (HH) se utiliza para evaluar el uso del agua. Sin embargo, su cálculo depende del alcance otorgado. Los objetivos de este trabajo fueron: calcular la HHtotal de tres procesos industriales, evaluar la influencia de cada componente (azul, gris e indirecto) sobre la HHtotal y analizar cómo varía esta ante cambios en el alcance. Se cuantificó la HHtotal para tres procesos: agua embotellada, cuero y cerveza. La HHtotal se obtuvo como la suma de un aporte directo (agua dulce y agua para dilución de contaminantes) y otro indirecto (equipos, energía, materias primas). Seguidamente, se realizó un análisis de sensibilidad para evaluar la HHtotal al excluir del cálculo: la materia prima, la electricidad, y ambas. La HHindirecta fue la que más influyó sobre la total. La HHindirecta de la curtiembre y cervecera se redujo un 95%, al excluir la HH de la materia prima, sin afectar la del agua embotellada. Excluir la electricidad impactó solamente en la HH del agua embotellada. Al eliminar ambas, la HHdirecta fue la que más pesó. La definición del alcance para cada proceso impacta en la HHtotal y consecuentemente en la toma de decisiones respecto a un uso sustentable del agua de cada industria.; The water footprint (WF) is used to assess water use. However, its calculation depends on the scope established. The aims of this study were: to calculate the WFtotal of three industrial processes, to assess the inuence of each component (blue, grey, and indirect) on the WFtotal , and to analyze how the WF varies with changes in the scope. WFtotal was quantied for three processes: bottled water, leather, and beer. WFtotal was obtained as the sum of a direct (freshwater and water for pollutant dilution) and an indirect contribution (equipment, energy, and raw materials). A sensitivity analysis was conducted to assess the WF when excluding from its calculation: raw materials, electricity, and both. WFindirect was the one which weighted the most on the total. Excluding the WF from raw materials reduced the WFindirect of the leather and beer industries by 95%, without aecting the bottled water process. Excluding electricity only impacted the WF of bottled water. When both were excluded, the WFdirect became the most signicant. The denition of the scope for each process aects the WF and, consequently, the decision-making regarding sustainable water use by each industry.

Tensiones, reificación y mediaciones en redes sociales: el caso de la formación de grupos cognitivos en Facebook y la construcción de símbolos digitales en Whatsapp Perpetuo, Leonardo Gabriel El presente trabajo analiza tensiones inmanentes en la dinámica de plataformas de redes sociales actuales que afectan al intercambio interdialógico y la construcción de conocimiento. La propuesta se centra, en primer lugar, en abordar la tensión reificación-pluralidad que atraviesa a grupos cognitivos emergentes de las áreas de Ciencias Sociales y Humanidades que se nuclean en la plataforma Facebook. Y, en segundo lugar, se hace hincapié en la construcción centralizada de los símbolos digitales en la plataforma de mensajería Whatsapp, afectando a la relación representatividad e inclusión en las comunidades de significación y a la comunicación horizontal de las mismas.; His work analyzes immanent tensions in the dynamics of current social media platforms that affect the interdialogical construction and co-construction of information and knowledge. The proposal focuses, first of all, on the reification-plurality tension that runs through emerging cognitive groups that demonstrate disciplinary intersections in the areas of Social Sciences and Humanities that are brought together on the Facebook platform. Furthermore, secondly, emphasis is placed on the centralized construction of digital symbols on the WhatsApp messaging platform, affecting the relationship between representativeness and inclusion in communities of significance and their horizontal communication.

Inquietudes en torno a la forma política estatal ante la tecnificación moderna: la mirada de Carl Schmitt durante el período de entreguerras; Concerns About the Political Form of the State in the Face of Modern Technification: Carl Schmitt's View During the Inter-war Period Manzullo Pawloff, Gonzalo Jorge En el presente escrito pretendemos recuperar las reflexiones de Carl Schmitt en torno al surgimiento, eficacia y potencialidad de la forma política estatal en vistas del diagnóstico que el propio autor revela respecto de la tecnificación moderna. Así, mostraremos cómo la forma política Estado resulta una innovación técnica específicamente moderna, pero no por ello exenta de paradojas ni problemas en tanto Schmitt se detiene a sopesar su vitalidad en el período de entreguerras europeo. Específicamente, daremos cuenta de cómo la dimensión de neutralización despolitizante de la religión de la tecnicidad, que ataca la autonomía de lo político, impacta sobre vigencia de la forma política Estado y abre preguntas sobre el orden jurídico en la Modernidad en la obra de Carl Schmitt. El jurista alemán declaró abiertamente en 1929 que vivía en la era de la religión de la tecnicidad, reflexionando sobre el desafío que ello impone para el despliegue de lo político, el orden común, la forma política Estado y la decisión.; In this paper we intend to recover Carl Schmitt's reflections on the emergence, efficacy and potentiality of the political state form, specially taking account of the author's own diagnosis of modern technification. Thus, we will show how the political form State is a specifically modern technical innovation, in any case free of paradoxes and problems, as Schmitt stops to weigh its vitality in the European interwar period. Specifically, we will show how the depoliticizing neutralizing dimension of the religion of technicity, which attacks the autonomy of the political, impacts on the validity of the political form State and opens questions about the legal order in Modernity in the work of Carl Schmitt. The German jurist openly declared in 1929 that he lived in the era of the religion of technicality, reflecting on the challenge that this imposes on the deployment of the political, the common order, the political form State and the decision.

Formas de un encuentro diferido: diálogos y cartas en Mi vida con Carlos (Germán Berger, 2009); Forms of a posponed encounter: dialogues and letters in My life with Carlos (Germán Berger, 2009) Aimaretti, Maria Gabriela Inserto en una investigación en la que se examina la interpretación que distintas generaciones han hecho sobre su experiencia política en los largos sesenta y la transición democrática en Chile, este trabajo analiza el film Mi vida con Carlos (2010) dirigido por German Berger. Utilizamos herramientas metodológicas de la historia cultural y de los estudios sobre cine latinoamericano, que se articulan con los insumos teóricos de los estudios de memoria y los de cine documental. Primero, se realiza una contextualización panorámica de las condiciones que hicieron posible la cinta, y luego se avanza sobre su análisis narrativo y visual, enfocándose en los modos en que la primera persona del narrador dialoga con una serie variada de materiales, dispositivos y voces que le permiten, de modo parcial, aproximarse a zonas ocultas o literalmente vacíos de su propia historia y la de su padre, el militante mirista Carlos Berger, asesinado y desaparecido por la Caravana de la muerte en 1973.; As part of an investigation in progress that examines the interpretation that different generations have made of their political experience in the long sixties and the democratic transition in Chile, this work analyses the film My Life with Carlos (2010) directed by German Berger. We use methodological tools from cultural history and studies on Latin American cinema, which are articulated with the theoretical inputs from memory studies and documentary film studies. First, a panoramic contextualization of the conditions that made the film possible is carried out, and second, the narrative and visual analysis is advanced, focusing on how the first person of the narrator dialogues with a varied series of materials, devices and voices that allow him, in a partial way, to approach hidden or literally empty areas of his own history and that of his father, the murdered PCC militant Carlos Berger, disappeared by the Caravan of Death in 1973.

Reescribir la historia: epoché y reducción en la literatura argentina reciente; Rewriting history: epokhé and reduction in recent argentinian literature Roggero, Jorge Luis Este artículo se propone utilizar las categorías fenomenológicas de la epoché y la reducción para indagar en dos novelas argentinas recientes (La estirpe de Carla Maliandi y Las aventuras de la China Iron de Gabriela Cabezón Cámara) que pueden pensarse como una intervención respecto de nuestro presente. Es necesaria una reescritura que permita reformular los supuestos con los que la literatura fundacional de nuestro país propuso la constitución de la comunidad nacional, para postularla en términos más justos e inclusivos.; This article proposes to use the phenomenological categories of epoché and reduction to investigate two recent Argentine novels (La estirpe by Carla Maliandi and Las aventuras de la China Iron by Gabriela Cabezón Cámara) that can be thought of as an intervention with respect to our present. A rewriting is needed to reformulate the assumptions with which the founding literature of our country proposed the constitution of the national community, to postulate it in fairer and more inclusive terms.
