Freiberg Hoffmann, Agustín; Romero Medina, Agustin; Vigh, Carlos Donato; Sánchez Rosas, Javier; Fernandez Liporace, Maria Mercedes
Academic resilience is the ability to achieve successful results in academic challenges. Since it is an accurate predictor of academic achievement and retention in undergraduates, measuring it is essential.The study aimed at developing a short version of the Academic Resilience Scale (ARS) as well as testing the bifactor model, posed in prior research as an alternative to first-order structures. Items were altered to become linguistically suitable for the target population and examined in terms of content. An exploratory factor analysis (300 undergraduates) retained 12 out of the 30 items ?four per dimension? considering their content and metric features. Confirmatory factor analysis and exploratory structural equation modeling analysis tested and compared different models in 805 undergraduates. As a result, the bifactor ESEM model including three independent dimensions and a global dimension was selected due to its better fit. The short scale enables a valid, reliable and fast assessment of academic resilience in undergraduates.Keywords: Academic resilience, bifactor model, college students, coping skills, psychometric features, short version.

Context. The optimum gypsum form and rate required to ameliorate soil sodicity constraints caused by supplementary irrigation with water containing sodium bicarbonate in humid regions are unknown. Aim. Evaluate the short-term effect of different gypsum forms and rates on (i) soil physicochemical properties and (ii) grain yield in a barley (Hordeum vulgare L.)/maize (Zea mays L.) sequence. Methods. We conducted two field experiments in the southeastern Argentinean Pampas on soils with low electrical conductivity (0.2 dS m−1), assessing three forms of gypsum (granulated, pelletised, and powdered) applied a month before barley sowing at 2000 kg ha−1.In one experiment, 3000 kg ha−1 was also tested. Soil properties and grain yield were determined at barley and maize harvests (i.e. 7 and 13 months after the gypsum application, respectively). Key results. (i) Gypsum did not significantly affect soil physical properties; (ii) powdered gypsum at 3000 kg ha−1 enhanced soil chemical properties at barley harvest, decreasing pH by 7% and exchangeable sodium percentage by 35%, while increasing the exchangeable Ca2+/Na+ ratio by 70% (0.0–0.1 m depth); (iii) powdered gypsum improved soil chemical conditions at deeper soil depths (0.1–0.2 m) at maize harvest; (iv) barley grain yield increased with gypsum application; and (v) maize yield was negatively correlated with soil pH and positively correlated with the Ca2+/Na+ ratio. Conclusions. Powdered gypsum can rapidly improve soil chemical properties and increase crop yields. Implications. Powdered gypsum, especially at 3000 kg ha−1, could be used to alleviate soil sodicity issues in the short-term.
El enfoque de sistemas complejos: La interdisciplinaridad en el abordaje clínico del proceso salud-enfermedad/bienestar
El enfoque de sistemas complejos: La interdisciplinaridad en el abordaje clínico del proceso salud-enfermedad/bienestar; The Complex Systems Approach: Interdisciplinarity in the Clinical Approach to the Health-Illness/Wellness Process
Vicco, Miguel Hernán; Federico, Lucía; Giri, Leandro Ariel
A lo largo de los años, la práctica sanitaria y los planes de estudios en medicina se han polarizado en dos facciones: el reduccionismo y el holismo, que se consideran opuestas y no vinculadas entre sí. Los partidarios de cada postura aún discuten cómo abordar a una persona que padece una enfermedad y la eficacia de su resolución.En este contexto, evaluamos la aplicabilidad del marco epistemológico de los Sistemas Complejos como un enfoque alternativo al reduccionismo biológico para analizar el proceso salud-enfermedad. Según dicho marco, al proceso salud-enfermedad/bienestar conviene modelarlo como un sistema complejo cuyos componentes no pueden ser seccionados y estudiados desde la perspectiva individual de cada subdisciplina interesada. Por el contrario, consta de un número considerable de variables que admiten múltiples dimensiones e interacciones entre ellas. Por tanto, su planteo debe ser necesariamente interdisciplinario, y los profesionales de la salud deben abordar el tema desde una perspectiva integradora, incluyendo el entorno social. Sesgar el enfoque holístico lleva a rechazar los aspectos subjetivos del individuo y de las propiedades de las relaciones entre los subsistemas que constituyen el sistema salud-enfermedad/bienestar.A diferencia de otras propuestas sistémicas de la literatura, el marco de sistemas complejosde Rolando García no se basa en la suma de conocimientos disciplinarios de los diferentes subsistemas sino en la integración de conceptos disciplinarios interdefinibles.La diferencia entre este enfoque y el multidisciplinario clásico es que la integración requiereque todos los miembros del equipo trabajen juntos en el modelado de la teoría para crear un lenguaje unificado para el sistema complejo, en lugar de trabajar desde una postura disciplinaria y luego sumar todos los puntos de vista.; Over the years, healthcare practice and curricula in medicine have polarised into two factions: reductionism and holism, which are seen as opposing and unconnected. Proponents of each position still argue about how to approach a person suffering from a disease and the efficacy of its resolution. In this context, we assessed the applicability of the Complex Systems epistemological framework as an alternative approach to biological reductionism in addressing the health-illness process. According to this framework, the health-illness/wellness process should be modelled as a complex system whose components cannot be sectioned and studied from the individual perspective of each sub-discipline concerned. On the contrary, it consists of a considerable number of variables with multiple dimensions and interactions between them. Therefore, its approach must necessarily be interdisciplinary, and health professionals must approach the subject from an integrative perspective, including the social environment. Biasing the holistic approach leads us to reject the analysis of the individual himself and the properties of the relationships between the subsystems that constitute the system. Unlike other systemic approaches in the literature, Rolando García’s Complex systems framework is not based on the sum of disciplinary knowledge from different sub-systems but on the integration of interdefinable disciplinary concepts. The difference between this approach and the classical multidisciplinary approach is that integration requires all team members to work together in modelling the theory to create a unified language for the complex system, rather than working from a disciplinary stance and then summing up all viewpoints.
Shaping multilateral regional governance of climate and forests: Exploring the influence of Forest industry lobbying on state participation
Shaping multilateral regional governance of climate and forests: Exploring the influence of Forest industry lobbying on state participation
Polo Villanueva, Fredy David; Schaub, Simon; Rivadeneira, Laura; Tosun, Jale; Giessen, Lukas; Burns, Sarah Lilian
This study aims to characterise the institutional dynamics of Multilateral Regional Governance Arrangements at the Climate-Forest Interface (MRGA-CFI) and investigate the influence of the forest industry lobby groups on state participation in these arrangements. We use an original dataset to characterise the issue scope, spatial ambit, and governance functions of MRGA-CFI. State participation in these arrangements is modelled as a function of the strength of the forest industry lobby groups; measured as the proportion of forest that has been planted in a state, alongside various control variables. Our findings reveal that most MRGA-CFI focus on forests but are relevant for climate issues, have contiguous spatial ambit primarily in Asia and Africa, and focus on knowledge dissemination and capacity building. Quantitative analysis reveals a positive significant association between the strength of the forest industry lobby groups and state participation in MRGA-CFI. The analysis further suggests that states with stronger forest industry lobby groups are more likely to participate in non-centralised arrangements and those that focus on forest but not climate. Conversely, such states are also less likely to participate in governance arrangements that focus on both forest and climate issues. We conclude that while regional cooperation on climate and forests has been designed to capture funds from the climate regime and form negotiating coalitions, the forest industry lobbies governments to prevent such cooperation from overregulating their economic activities.
Protección legal del ambiente y la Agenda 2030 en la actualidad argentina
Protección legal del ambiente y la Agenda 2030 en la actualidad argentina; Environmental legal protection and 2030 Agenda in present Argentina
Minaverry, Clara María; Caceres, Veronica Lucia
El presente trabajo considera los cambios recientes que se introdujeron en la legislación ambiental de Argentina durante 2024, que tienen incidencia sobre los objetivos establecidos en la Agenda 2030 que se vinculan con la biodiversidad y el cambio climático y en el rol internacional que cumple el país. La investigación se basó en una metodología cualitativa que enfatiza la atención en la legislación ambiental nacional y en el contenido de dos normas claves sancionadas durante 2024: el Decreto de Necesidad y Urgencia Nº 70/2023 y la Ley Nº 27.742 de Bases y Puntos de Partida para la Libertad de los Argentinos. Además, se relevaron y analizaron los objetivos de la Agenda 2030 y una selección de informes elaborados en el ámbito de dos organismos internacionales sectoriales especializados la protección de la biodiversidad y la lucha contra el cambio climático: IPBES e IPCC. Se concluye que las actuales modificaciones en la regulación son regresivas en materia ambiental, inciden negativamente en la biodiversidad y en la lucha contra el cambio climático, impactan en los compromisos que asumió el país en la Agenda 2030 y es contrario a las tendencias promovidas por los organismos internacionales de los cuales el país es parte.; This paper considers the recent changes which were introduced in the environmental legislation of Argentina during 2024, which have an impact on the 2030 Agenda Goals which are related to biodiversity and climate change and with the international role of the country. This research was based on a qualitative methodology which focus on national environmental legislation and on the content of two key regulations sanctioned during 2024: the Decree of Necessity and Urgency No. 70/2023 and Law 27,742 named Bases and Starting Points for the Freedom of Argentines. In addition, 2030 Agenda goals and a selection of reports prepared within the scope of two sectoral international organizations specialized in biodiversity and climate change were surveyed and analyzed: IPBES and IPCC. It is concluded that the current modifications in the regulation are regressive in connection with the environmental area, have a negative impact on biodiversity and in relation with the fight against climate change, it impacts the commitments made by the country in the 2030 Agenda and are contrary to the trends promoted by the international organizations of which the country is a part.

Entre el archivo y el archivista: Reconstrucción y gestión del archivo sonoro de Carlos Vega; Between the archive and the archivist: Reconstruction and management of the sound archive of Carlos Vega
Adduci Spina, Elina
El archivo sonoro fundacional del Instituto Nacional de Musicología Carlos Vega (INM) fue generado por Carlos Vega como un objeto de estudio para examinar y clasificar las músicas populares de Argentina y Latinoamérica. Las investigaciones musicológicas de Vega se han convertido en un objeto de análisis en sí mismo. Sin embargo, ni Vega ni sus sucesores han puesto especial atención en la reflexión de la praxis de producción y clasificación documental. El presente artículo indaga la política documental desarrollada por Carlos Vega con el propósito de proponer una metodología posible para la gestión de su acervo. En primer lugar, se estudian los modos de creación, catalogación y selección iniciados por Vega y continuados por el instituto. En segundo lugar, se expone una serie de estrategias adoptadas en pos del abordaje integral y procesual del archivo sonoro institucional del INM.; The foundational sound archive of the Instituto Nacional de Musicología «Carlos Vega» (INM) was generated by Carlos Vega as an object of study to examine and classify the popular music of Argentina and Latin America. In turn, Vega’s musicological research has become an object of analysis in itself. However, neither Vega nor his successors have paid special attention to the reflection of the praxis of documentary production and classification. Therefore, this article investigates the documentary policy developed by Carlos Vega in order to propose a possible methodology for the management of his collection. First of all, the modes of creation, cataloguing and selection initiated by Vega and continued by the institute are studied. Secondly, a series of strategies adopted in pursuit of the integral and procedural approach of the institutional sound archive of the INM is exposed.
Photometric and numerical study of comet C/2021 A1 (Leonard) near its estimated disruption date
Photometric and numerical study of comet C/2021 A1 (Leonard) near its estimated disruption date
Garcia, R. S.; Fernandez Lajus, Eduardo Eusebio; Di Sisto, Romina Paula; Gil Hutton, Ricardo Alfredo
Initially on an elliptical orbit, C/2021 A1 experimented significant changes in its orbital configuration due to planetary perturbations upon entering the planetary region. Images of the comet C/2021 A1 (Leonard) obtained in March 2022 allow to estimate that its disintegration occurred in December 2021. The aim of this paper is to analyze the comet’s dust behavior during the period when its disintegration is presumed to have commenced, so a series of images of this comet on the broadband B, V, and R filters were taken on December 21 and 23, 2021 with the 0.6 m Helen Sawyer Hogg (HSH) telescope at the Complejo Astron´omico El Leoncito (CASLEO) to do a morphological, photometric, and numerical analysis of this comet. Analysis of the magnitudes and dust production rate suggests a significant increase in activity on December 21 compared to two days later, indicating a potential outburst. Digital filters were applied to enhance contrast in the cometary images, revealing two active regions on opposite sides of the nucleus. Additionally, the A(0◦) f ρ parameter was obtained for this comet. Finally, to gain deeper insights into Leonard’s dust behavior,observations were fitted to a newly developed theoretical model for studying dust comas. Combined with photometric data and gas production information from the literature, the analysis suggests that the comet’s activity on December 21, 2021, may mark the beginning of its disintegration.

Chronic NOD2 stimulation by MDP confers protection against parthanatos through M2b macrophage polarization in RAW264.7 cells
Mansilla, Florencia Celeste; Miraglia, Maria Cruz; Maidana, Silvina Soledad; Randazzo, Cecilia Paola; Capozzo, Alejandra Victoria
Innate immune cells show enhanced responsiveness to secondary challenges after an initial non-related stimulation (Trained Innate Immunity, TII). Acute NOD2 activation by Muramyl-Dipeptide (MDP) promotes TII inducing the secretion of pro-inflammatory mediators, while a sustained MDP-stimulation down-regulates the inflammatory response, restoring tolerance. Here we characterized in-vitro the response of murine macrophages to lipopolysaccharide (LPS) challenge under NOD2-chronic stimulation. RAW264.7 cells were trained with MDP (1 μg/ml, 48 h) and challenged with LPS (5 μg/ml, 24 h). Trained cells formed multinucleated giant cells with increased phagocytosis rates compared to untrained/challenged cells. They showed a reduced mitochondrial activity and a switch to aerobic glycolysis. TNF-α, ROS and NO were upregulated in both trained and untrained cultures (MDP+, MDP- cells, p > 0.05); while IL-10, IL-6 IL-12 and MHCII were upregulated only in trained cells after LPS challenge (MDP + LPS+, p < 0.05). A slight upregulation in the expression of B7.2 was also observed in this group, although differences were not statistically significant. MDP-training induced resistance to LPS challenge (p < 0.01). The relative expression of PARP-1 was downregulated after the LPS challenge, which may contribute to the regulatory milieu and to the innate memory mechanisms exhibited by MDP-trained cells. Our results demonstrate that a sustained MDP-training polarizes murine macrophages towards a M2b profile, inhibiting parthanatos. These results may impact on the development of strategies to immunomodulate processes in which inflammation should be controlled.

Butierrez, Luis Fernando
En este artículo estudio la influencia del pensamiento de Heidegger en el marco de las consideraciones de los lazos sociales y comunitarios de Byung-Chul Han, y sus respectivos enfoques críticos respecto de la tradición metafísica de la subjetividad. Mediante el análisis de cómo Han articula sus interpretaciones críticas de la analítica de Sein und Zeit, en el marco de sus propios planteamientos sociopolíticos contemporáneos, busco distinguir continuidades y diferencias entre ambas perspectivas. De esta manera me propongo poner en evidencia ambas comprensiones del existente humano articuladas en torno a los lazos sociales, para dar cuenta de sus alcances respectivos.; In the following paper we will distinguish the influence of Heidegger’s thought within the framework of Byung-Chul Han’s considerations of social and communal bonds, and their respective critical approaches to the metaphysical tradition of subjectivity. Analyzing the way Han articulates his critical interpretations of Sein und Zeit’s analytic within the framework of his own contemporary sociopolitical analyses, we will seek to distinguish continuities and differences between the two perspectives. In this way we intend to highlight both understandings of the human existent articulated around social ties, to account for their respective scopes.; No trabalho a seguir, distinguiremos a influência do pensamento de Heidegger nas elaborações de Byung Chul Han no quadro de suas considerações sobre os laços sociais e comunitários e de suas respectivas abordagens críticas à tradição metafísica da subjetividade. Partindo da análise da forma como Han articula suas interpretações críticas da analítica de Sein und Zeit, no quadro de suas próprias análises político-sociais contemporâneas, buscaremos distinguir continuidades e diferenças entre as duas perspectivas. Dessa forma, propomos destacar ambas as compreensões do ser humano existente articulado em torno dos laços sociais, para dar conta de seus respectivos alcances.

Datos de curvas de producción de CO2 y DO en fermentaciones con levaduras contaminantes de sidras de pera. Se informan los valores observados y los modelados junto con las curvas a lo largo del tiempo
Se realizaron fermentaciones de mosto de pera en erlenmeyers de 50 ml, cada uno con 35 ml de mosto obtenido de un productor local, el cual fue esterilizado mediante filtración (0,22 μm). Estos se inocularon con levaduras contaminantes aisladas en el estudio, a saber, Zygosaccharomyces parabailii NPCC1791, Brettanomyces custersianus NPCC1813, o Brettanomyces bruxellensis NPCC1792, en una concentración final de 2 × 106 células/mL, por triplicado. Los matraces incubaron a 20 °C sin agitación durante 5 meses y se midieron densidad óptica (OD) y pérdida de peso (debido al CO2 liberado) hasta el final del ensayo. Los parámetros de crecimiento, incluido el crecimiento específico máximo, la velocidad (μ) y la duración de la fase de retraso (λ), se calcularon para ambos indicadores DO y CO2 utilizando una ecuación de Gompertz modificada propuesta por Zwietering et al. Los datos de crecimiento de cada tratamiento se ajustaron mediante un procedimiento de regresión no lineal que minimizó la suma de los cuadrados de la diferencia entre datos experimentales y el modelo ajustado, conocido como función de pérdida (observada - predicha). Este análisis fue realizado utilizando el módulo no lineal de Statistica 7.0 paquete de software con la opción Quasi-Newton (StatSoft,Tulsa, Oklahoma, EE. UU.)

Psychometric properties and Longitudinal Measurement Invariance of the Spanish version of the Alcohol Expectancies Questionnaire Short Form among young adult binge drinkers
Psychometric properties and Longitudinal Measurement Invariance of the Spanish version of the Alcohol Expectancies Questionnaire Short Form among young adult binge drinkers
González Ponce, Bella M.; Pilatti, Angelina; Rivarola Montejano, Gabriela Belen; Bravo, Adrian J.; Fernández Calderón, Fermín
Background: Longitudinal Measurement Invariance (LMI) is critically important to evaluate changes in alcohol expectancies over time. However, past research has not explored the longitudinal properties of the Spanish Expectancy Questionnaire Short Form (EQ-SF).Objectives: To examine the reliability, sources of validity (structural, invariance across sex, and concurrent validity), and LMI of the Spanish EQ-SF among young adults who engage in binge drinking.Methods: Participants (n = 279; 48.4% female) completed the EQ-SF and, two months later, completed it again along with measures of alcohol use, drinking motives, and protective behavioral strategies (PBS). We performed confirmatory factor analysis for structural validity and measurement invariance analysis for longitudinal and sex stability.Results: The eight-factor intercorrelated model (i.e. social facilitation, fun, sexual disinhibition, tension reduction, antisocial effects, negative emotional states, negative physical effects, and cognitive impairments) provided the best fit (χ2(df) = 497.29(224), CFI = .962, RMSEA = .064, SRMR = .049). This model was invariant across sex and time. Reliability coefficients (Ordinal alpha) for each dimension were consistently strong at both time points (from .72 to .93 at T1 and .73 to .91 at T2). Positive alcohol expectancies at baseline were positively related to alcohol use and drinking motives and negatively related to PBS at follow-up, demonstrating predictive validity.Conclusion: Our results support the temporal invariance of the EQ-SF scores among Spanish young adults who engage in binge drinking. The evidence supports the suitability of this measure for accurately assessing changes in alcohol expectancies over time in interventions aimed at preventing binge drinking in young adults.

Enjoyment in Sport and Alcohol Use among Adolescents: Examining the Mediating Role of Engagement
Enjoyment in Sport and Alcohol Use among Adolescents: Examining the Mediating Role of Engagement
Background: Alcohol consumption among young people is a significant public health concern. Previous studies have indicated that participation in sports, through the positive experiences it offers, may function as a protective factor for alcohol intake. This study aims to examine the influence of enjoyment and personal fulfillment on adolescent alcohol use, exploring the role of engagement with sports as a mediating variable. Method: A total of 370 adolescents (Mean age = 15.08; SD = 1.48) participated in the study and completed the Alcohol Use Disorder Identification Test, the Enjoyment in Sports Scale, and the Athlete Engagement Questionnaire. Results: The results demonstrated that enjoyment is related to lower alcohol consumption through personal fulfillment and engagement in the activity. Conclusions: It is crucial to facilitate positive experiences in sport that promote engagement and generate a sense of personal fulfillment, as these factors may reduce the likelihood of risky alcohol consumption.

Estudio de los silicofitolitos de tres especies de Solanaceae silvestres con registro de uso en poblaciones prehispánicas que habitaron el Delta del Paraná
Estudio de los silicofitolitos de tres especies de Solanaceae silvestres con registro de uso en poblaciones prehispánicas que habitaron el Delta del Paraná; Study of the silicophytoliths of three species of wild Solanaceae reported to be used in prehispanic populations that inhabited the Paraná Delta
Clauss, Samira; Colobig, María de Los Milagros; Ramos, Rita Soledad
Las plantas silvestres han tenido gran importancia en la subsistencia de las poblaciones arqueológicas que ocuparonel Delta del Paraná en momentos previos a la conquista española. Esto fue desconocido hasta hace pocos años, yaque en un comienzo se estudiaba su dieta a través de los recursos obtenidos mediante la caza y la pesca, ignorandola importancia que el mundo vegetal tenía en la vida cotidiana de estas personas. Debido a esto, el presente trabajobusca ser un aporte en el inicio de la confección de una colección de referencia de plantas locales que podrían habertenido diversos usos por parte de los habitantes de la región, con el fin de reducir los sesgos, y empezar a identificarespecies que no han sido contempladas hasta el momento. Se realizaron análisis de microrrestos biosilíceos en ordende identificar los silicofitolitos diagnósticos de las especies Solanum glaucophyllum Desf., Solanum pseudocapsicumL. y, Salpichroa origanifolia (Lam.) Baill. De acuerdo al registro etnográfico estas especies son de interés económicoporque forman parte del amplio listado de especies comestibles de la familia Solanaceae.; Wild plants have been of great importance in the subsistence of the archaeological populations that occupied the Delta of the Paraná River prior to the Spanish conquest. This was unknown until a few years ago, because initially their food was studied through the resources obtained by hunting and fishing, ignoring the importance that the plant world had in the daily life of these peoples. Because of this, the present work aims to be a significant contribution in the beginning of the elaboration of a reference collection of local plants that could have had diverse uses by the inhabitants of the region, in order to reduce biases and begin to identify species that have not been considered so far. Analyses of biosiliceous microrrests were carried out in order to identify diagnostic phytoliths of the species Solanum glaucophyllum Desf., Solanum pseudocapsicum L. and Salpichroa origanifolia (Lam.) Baill. According to the ethnographic record, these species are of economic interest because they are part of the extensive list of edible species of the Solanaceae family.
