Lxs hijxs del encierro: interés superior del niñx vs. poder punitivo del Estado : Suspensión de la patria potestad en madres privadas de la libertad

Realizado en el marco de una investigación de campo sobre la situación de las madres privadas de su libertad que conviven junto a sus hijos e hijas en la Unidad 33 de Los Hornos (Departamento Judicial de La Plata, Provincia de Buenos Aires), este trabajo pone énfasis en la dicotomía existente entre la normativa de fondo y de forma respecto al ejercicio de hecho de una patria potestad que, según el artículo 12 del actual Código Penal, se encuentra suspendida para ciertas mujeres. Conjuntamente con ello, se plantean algunos interrogantes acerca de la política criminal y carcelaria, la mirada del sistema penal sobre esos niños y niñas y las posibles alternativas existentes ante estas situaciones, intentando homogenizar lo jurídico con lo sociológico desde una perspectiva de derechos humanos. En pos de ello, es que el presente utiliza un lenguaje género sensitivo, cumpliendo de esta manera con los estándares establecidos para la no discriminación en razón del lenguaje.Facultad de Ciencias Jurídicas y Sociale

Spectral Properties of Brain Activity Under Two Anesthetics and Their Potential for Inducing Natural Sleep in Birds

Both mammals and birds exhibit two sleep states, slow wave sleep (SWS) and rapid eye movement (REM) sleep. Studying certain aspects of sleep-related electrophysiology in freely behaving animals can present numerous methodological constraints, particularly when even fine body movements interfere with electrophysiological signals. Interestingly, under light general anesthesia, mammals and birds also exhibit slow waves similar to those observed during natural SWS. For these reasons, slow waves occurring under general anesthesia are commonly used in the investigation of sleep-related neurophysiology. However, how spectral properties of slow waves induced by anesthesia correspond to those occurring during natural SWS in birds has yet to be investigated systematically. In this study, we systematically analyzed spectral properties of electroencephalographic (EEG) patterns of pigeons (Columba livia) occurring under two commonly used anesthetics, isoflurane and urethane. These data were compared with EEG patterns during natural sleep. Slow waves occurring during spontaneous SWS, and those induced with isoflurane and urethane all showed greatest absolute power in the slowest frequencies (<3 Hz). Isoflurane and urethane-induced slow waves had near-identical power spectra, and both had higher mean power than that observed during SWS for all frequencies examined (0–25 Hz). Interestingly, burst suppression EEG activity observed under deeper planes of isoflurane anesthesia could occur bihemispherically or unihemispherically. Electrophysiological patterns while under isoflurane and urethane share phenomenological and spectral similarities to those occurring during SWS, notably the generation of high amplitude, slow waves, and peak low-frequency power. These results build upon other studies which suggest that some anesthetics exert their effects by acting on natural sleep pathways. As such, anesthesia-induced slow waves appear to provide an acceptable model for researchers interested in investigating sleep-related slow waves utilizing electrophysiological methods not suitable for use in freely behaving birds

Indicadores utilizados para evaluar la sustentabilidad integral de los sistemas de producción de leche con énfasis en el impacto ambiental

En este trabajo se presenta una revisión de los principales indicadores utilizados en diferentes países para evaluar la sustentabilidad integral de los sistemas lecheros, realizando hincapié en aquellos indicadores que pueden ser utilizados en la gestión ambiental de los predios en la Argentina. El conocimiento y la sensibilización actual sobre el impacto ambiental y en menor medida, de la producción animal en particular, han desencadenado la investigación sobre el desarrollo de indicadores para evaluar la sustentabilidad ambiental, como por ejemplo los balances de nutrientes, el consumo y la eficiencia en el uso de la energía y el agua, y las emisiones de los sistemas productivos. Estos indicadores deben ser analizados en conjunto con indicadores físicos y económicos utilizados en estos sistemas productivos. La utilización de los mismos ha permitido tener una aproximación del impacto que las prácticas agropecuarias tienen en un sistema productivo y agroecosistema determinado. Los indicadores a escala predial facilitan a los productores el diagnóstico para poder actuar en consecuencia e ir mejorando su condición frente a normativas de regulación que exigen los diferentes mercados y normativas incipientes en las diferentes regiones productivas del país. Encontrar el equilibrio entre la producción lechera y el grado de impacto que puede ser aceptable para la sociedad, es la clave para lograr la producción lechera sustentable, reduciendo al mínimo la contaminación del agua, aire y suelo, preservando y mejorando el medio natural y haciendo un uso racional de los recursos.EEA RafaelaFil: Tieri, Maria Paz.

Network-based validation of the psychometric questionnaire EDI-3 for the assessment of eating disorders

Assessing the validity of a psychometric test is fundamental to ensure a reliable interpretation of its outcomes. Few attempts have been made recently to complement classical approaches (e.g., factor models) with a novel technique based on network analysis. The objective of the current study is to carry out a network-based validation of the Eating Disorder Inventory 3 (EDI-3), a questionnaire designed for the assessment of eating disorders. Exploiting a reliable, open source sample of 1206 patients diagnosed with an eating disorder, we set up a robust validation process encompassing detection and handling of redundant EDI-3 items, estimation of the cross-sample psychometric network, resampling bootstrap procedure and computation of the median network of the replica samples. We then employed a community detection algorithm to identify the topological clusters, evaluated their coherence with the EDI-3 subscales and replicated the full validation analysis on the subpopulations corresponding to patients diagnosed with either anorexia nervosa or bulimia nervosa. Results of the network-based analysis, and particularly the topological community structures, provided support for almost all the composite scores of the EDI-3 and for 2 single subscales: Bulimia and Maturity Fear. A moderate instability of some dimensions led to the identification of a few multidimensional items that should be better located in the intersection of multiple psychological scales. We also found that, besides symptoms typically attributed to eating disorders, such as drive for thinness, also non-specific symptoms like low self-esteem and interoceptive deficits play a central role in both the cross-sample and the diagnosis-specific networks. Our work adds insights into the complex and multidimensional structure of EDI-3 by providing support to its network-based validity on both mixed and diagnosis-specific samples. Moreover, we replicated previous results that reinforce the transdiagnostic theory of eating disorders
