Practice of physical activity and perceived environment of users of the Unified Health System; Práctica de actividad física y ambiente percibido de usuarios del Sistema Único de Salud; Prática de atividade fí­sica e ambiente percebido de usuários do Sistema Único de Saúde Parisi Hodniki, Paula; de Souza Teixeira, Carla Regina; Zanetti, Maria Lúcia; de Moraes, Camila; Fermino, Rogerio Cesar; Berra, Silvina del Valle Objective: to analyze the relationship between leisure-time physical activity and active commuting with the perception of the environment in people with chronic non-communicable diseases. Methods: cross-sectional study consisting of 719 SUS users. For data collection, the IPAQ and the Neighborhood Environmental Walkability Scale were used. Pearson’s chi-square test and logistic regression model were used. Results: of the 719 (100%), 512 (71.2%) participants were female and 504 (70.1%) reported having a chronic non-communicable disease. There are no relationships between women with chronic disease and perception of the environment for the practice of physical activity during leisure and active commuting. On the other hand, men and the elderly were more likely to be more active in the practice of physical activity. Conclusion: interventions to increase the practice of physical activity in women should be implemented in order to prevent and treat chronic non-communicable diseases.; Objetivo: analizar la relación entre la actividad física com el nfer libre y los desplazamientos activos com la percepción del entorno com personas com nfermidades crónicas no transmisibles.

Conclusão: intervenções para incrementar a prática de atividade fí­sica em mulheres devem ser implementadas com vistas a prevenção e tratamento das doenças crônicas não transmissí­veis.

Identification and characterization of soluble binding proteins associated with host foraging in the parasitoid wasp Diachasmimorpha longicaudata Wulff, Juan Pedro; Segura, Diego Fernando; Devescovi, Francisco; Muntaabski, Irina; Milla, Fabian Horacio; Scannapieco, Alejandra Carla; Cladera, Jorge Luis; Lanzavecchia, Silvia Beatriz The communication and reproduction of insects are driven by chemical sensing. During this process, chemical compounds are transported across the sensillum lymph to the sensory neurons assisted by different types of soluble binding proteins: odorant-binding proteins (OBPs); chemosensory proteins (CSPs); some members of ML-family proteins (MD-2 (myeloid differentiation factor-2)-related Lipid-recognition), also known as NPC2-like proteins. Potential transcripts involved in chemosensing were identified by an in silico analysis of whole-body female and male transcriptomes of the parasitic wasp Diachasmimorpha longicaudata. This analysis facilitated the characterization of fourteen OBPs (all belonging to the Classic type), seven CSPs (and two possible isoforms), and four NPC2-like proteins. A differential expression analysis by qPCR showed that eleven of these proteins (CSPs 2 and 8, OBPs 2, 3, 4, 5, 6, 9, 10, and 11, and NPC2b) were over-expressed in female antenna and two (CSP 1 and OBP 12) in the body without antennae. Foraging behavior trials (linked to RNA interference) suggest that OBPs 9, 10, and 11 are potentially involved in the female orientation to chemical cues associated with the host. OBP 12 seems to be related to physiological processes of female longevity regulation. In addition, transcriptional silencing of CSP 3 showed that this protein is potentially associated with the regulation of foraging behavior. This study supports the hypothesis that soluble binding proteins are potentially linked to fundamental physiological processes and behaviors in D. longicaudata. The results obtained here contribute useful information to increase the parasitoid performance as a biological control agent of fruit fly pest species.

Stress-Related Brain Neuroinflammation Impact in Depression: Role of the Corticotropin-Releasing Hormone System and P2X7 Receptor Silberstein Cuña, Susana Iris; Liberman, Ana Clara; Dos Santos Claro, Paula Ayelen; Ugo, Maria Belen; Deussing, Jan M.; Arzt, Eduardo Simon Depression and other psychiatric stress-related disorders are leading causes of disability worldwide. Up to date, treatments of mood disorders have limited success, most likely due to the multifactorial etiology of these conditions. Alterations in inflammatory processes have been identified as possible pathophysiological mechanisms in psychiatric conditions. Here, we review the main features of 2 systems involved in the control of these inflammatory pathways: the CRH system as a key regulator of the stress response and the ATP-gated ion-channel P2X7 receptor (P2X7R) involved in the control of immune functions. The pathophysiology of depression as a stress-related psychiatric disorder is depicted in terms of the impact of CRH and P2X7R function on inflammatory pathways in the brain. Understanding pathogenesis of affective disorders will lead to the development of therapies for treatment of depression and other stress-related diseases.

El altar del judío Nasas y la figura de Elías: ¿Sincretismo religioso en tiempos de Gregorio Magno? Laham Cohen, Rodrigo Jaime En este artículo se exploran las posibles explicaciones de la epístola III, 37 del Registrum Epistularum de Gregorio Magno, en la cual el papa exige castigar a un judío llamado Nasas que supuestamente había erigido un altar en nombre del profeta Elías al cual asistían cristianos. En el trabajo se presentan, primero, los análisis previos en torno a la misiva. Luego se analiza la factibilidad de los hechos allí narrados y cuál era la imagen de Elías y de los altares tanto en la obra de Gregorio Magno como en las literaturas judías y cristianas del período. De tal modo se busca indagar sobre qué pudo haber realizado Nasas en la Sicilia del siglo VI y reflexionar sobre nuestras limitaciones en el conocimiento del judaísmo europeo tardoantiguo.; Neste artigo explora-se as possíveis explicações da epístola III, 37 do Registrum Epistularum de Gregório Magno, em que o papa exige punir um judeu chamado Nasas que supostamente havia erguido um altar em nome do profeta Elias que era frequentado por cristãos. O trabalho apresenta, em primeiro lugar, as análises anteriores em torno da carta. Em seguida, analisa-se a viabilidade dos acontecimentos ali narrados e qual era a imagem de Elias e dos altares tanto na obra de Gregório Magno quanto nas literaturas judaica e cristã do período. Dessa forma, busca investigar o que Nasas poderia ter feito na Sicília do século VI e refletir sobre nossas limitações no conhecimento do judaísmo europeu tardo antigo.

Alcohol consumption leads to loss of healthy life, but the ADH1B*2 allele may still protect from NASH Mazzolini Rizzo, Guillermo Daniel; Canbay, Ali Nonalcoholic fatty liver disease (NAFLD) is now the most common cause of chronic liver disease worldwide, affecting almost a quarter of the world population (1,2), and is a main cause of severe hepatic complications such as cirrhosis and liver cancer. In histological assessment NAFLD and alcoholic liver disease (ALD) are difficult to distinguish; NAFLD diagnosis thus requires a limit of alcohol intake. However, NAFLD and ALD very frequently coexist in the same patient, making it difficult to identify the exact cause of liver complications. Almost 5?6% of all worldwide deaths (~3 million) are caused by the harmful use of alcohol (https://www.who.int/publications/i/item/9789241565639), therefore alcohol represents a major health problem at a global scale. There is an association between the amount of alcohol consumption and ALD, however, only 30% of chronic drinkers develop alcoholic hepatitis, and 10?20% progress to advanced fibrosis or cirrhosis (3), underscoring the role of genetic factors involved in disease severity and progression. Any level of alcohol consumption, regardless of the amount, leads to loss of healthy life. The recommendation in clinical practice should be to avoid alcohol intake, particularly in the presence of any liver disease. Moderate alcohol consumption has been reported by many studies to be associated with less severe NAFLD, although some of these cross-sectional studies may be affected by selection bias (4-6). In contrast a longitudinal analysis of liver biopsies from patients with NAFLD showed that modest alcohol consumption was associated with lower NASH resolution in comparison with nondrinkers (7). Recently, Chang et al. showed that the risk of liver steatosis in low and moderate alcohol consumers (MACs) was lower in comparison with nondrinkers (8); however, the proportion of hepatic steatosis plus fibrosis was higher in drinkers. The exact mechanism of the deleterious effect of alcohol consumption on NAFLD in obese patients is still unclear. When combined with free fatty acids the polyphenol resveratrol resulted in the stimulation of profibrogenic effects in hepatic stellate cells (key cells for induction and propagation of hepatic fibrosis) instead of any protective role (9). Therefore, it is important to shed light on the exact role of alcohol intake in addition to NAFLD to solve the currently rather conflicting data on this issue. The work published by Vilar-Gomez et al. in Gastroenterology (10) clarifies some knowledge gaps about alcohol metabolism and consumption, and the severity of NAFLD by studying the role of alcohol dehydrogenase (ADH)-1B, in particular ADH1B*2, in this context. The authors started from a finding generated in a previous work by Sookoian et al., where they observed that patients with low alcohol intake and the ADH1B*2 allele showed a less severe NAFLD by histology compared to other patients studied (11). Vilar-Gomez et al. studied 1,697 patients enrolled into various studies conducted by the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) over a period of 10 years [2009?2019]; the NASH CRN Pathology committee reviewed all liver biopsies, and comprehensive alcohol consumption was obtained by AUDIT and LDH questionnaire, binge and heavy drinkers were excluded (170 patients). Remarkably, the frequency of ADH1B*2 carriage varied across race being high in Asians/Pacific Islanders/Hawaiians (86%) and low in non-Hispanic whites (8%), Hispanics (14%), and Blacks (4%), but the study was focused on the 1,153 non-Hispanic whites, which were mainly female, obese, and hypertensive. Among the 1,153 patients, 30% had advanced fibrosis, and 60% had definite NASH. The cohort included 720 non-drinkers and 433 moderate drinkers, but no heavy alcohol consumers. ADH1B*2 carriers were more likely to be male, and moderate alcohol consumption was similar between ADH1B*1 and ADH1B*2 carriers

Ectopic expression of GmNHX3 and GmNHX1, encoding two Glycine max Na+/H+ vacuolar antiporters, improves water deficit tolerance in Arabidopsis thaliana Pardo, Esteban Mariano; Toum, Laila; Pérez Borroto, Lucía Sandra; Fleitas, L.; Gallino, J. P.; Machi, S.; Vojnov, Adrián Alberto; Castagnaro, Atilio Pedro; Welin, Björn The importance of Na+/H+ antiporters in salt tolerance in plants has been demonstrated in many studies, but much less is known about their protective role during drought stress. To study their possible contribution to water deficit tolerance, two closely related soybean Na+/H+ antiporters belonging to the intracellular NHX exchanger protein family, GmNHX3 and GmNHX1, were evaluated in transgenic Arabidopsis thaliana. A. thaliana plants ectopically expressing GmNHX3 or GmNHX1 displayed a more drought-tolerant phenotype compared to wild-type plants, which was accompanied by an increase in relative water content and chlorophyll content during stress conditions. Both GmHNX1 and GmHNX3 transgenic lines accumulated higher amounts of Na+ and K+ cations, showed increased antioxidant enzyme activities and less membrane damage due to lipid peroxidation under water deficit, as compared to non-transformed plants. Furthermore, plants expressing GmNHX3 showed an increased sensitivity to abscisic acid as deduced from stomatal closure and seed germination inhibition studies. Finally, a significant up-regulation of abiotic stress-related genes was observed in both transgenic lines compared to wild-type plants in response to abscisic acid and mannitol treatments. These results demonstrate that GmNHX3 and GmNHX1 antiporters confer protection during drought stress in A. thaliana and hence are potential genetic targets to improve drought tolerance in soybean and other crops.

Structural features of the plant N-recognin ClpS1 and sequence determinants in its targets that govern substrate selection Aguilar Lucero, Dianela Ailin; Cantoia, Alejo; Sánchez López, Magda Carolina; Binolfi, Andrés; Mogk, Axel; Ceccarelli, Eduardo Augusto; Rosano, German Leandro In the N-degron pathway of protein degradation of Escherichia coli, the N-recognin ClpS identifies substrates bearing N-terminal phenylalanine, tyrosine, tryptophan, or leucine and delivers them to the caseinolytic protease (Clp). Chloroplasts contain the Clp system, but whether chloroplastic ClpS1 adheres to the same constraints is unknown. Moreover, the structural underpinnings of substrate recognition are not completely defined. We show that ClpS1 recognizes canonical residues of the E. coli N-degron pathway. The residue in second position influences recognition (especially in N-terminal ends starting with leucine). N-terminal acetylation abrogates recognition. ClpF, a ClpS1-interacting partner, does not alter its specificity. Substrate binding provokes local remodeling of residues in the substrate-binding cavity of ClpS1. Our work strongly supports the existence of a chloroplastic N-degron pathway.

Replay of innate vocal patterns during night sleep in suboscines Döppler, Juan Francisco; Peltier, Manon; Amador, Ana; Goller, Franz; Mindlin, Bernardo Gabriel Activation of forebrain circuitry during sleep has been variably characterized as 'pre- or replay' and has been linked to memory consolidation. The evolutionary origins of this mechanism, however, are unknown. Sleep activation of the sensorimotor pathways of learned birdsong is a particularly useful model system because the muscles controlling the vocal organ are activated, revealing syringeal activity patterns for direct comparison with those of daytime vocal activity. Here, we show that suboscine birds, which develop their species-typical songs innately without the elaborate forebrain-thalamic circuitry of the vocal learning taxa, also engage in replay during sleep. In two tyrannid species, the characteristic syringeal activation patterns of the song could also be identified during sleep. Similar to song-learning oscines, the burst structure was more variable during sleep than daytime song production. In kiskadees (Pitangus sulphuratus), a second vocalization, which is part of a multi-modal display, was also replayed during sleep along with one component of the visual display. These data show unambiguously that variable 'replay' of stereotyped vocal motor programmes is not restricted to programmes confined within forebrain circuitry. The proposed effects on vocal motor programme maintenance are, therefore, building on a pre-existing neural mechanism that predates the evolution of learned vocal motor behaviour.

Differential inhibition of egg hatching in Aedes aegypti populations from localities with different winter conditions Campos, Raul Ernesto; Zanotti, Gabriela Alejandra; Di Battista, Cristian Matias; Gimenez, Javier Orlando; Fischer, Sylvia Cristina In Argentina, the mosquito Aedes aegypti (L.) (Diptera: Culicidae) is distributed from subtropical to temperate climates. Here, we hypothesized that the expansion of Ae. aegypti into colder regions is favoured by high-phenotypic plasticity and an adaptive inhibition of egg hatching at low temperatures. Thus, we investigated the hatching response of eggs of three populations: One from a subtropical region (Resistencia) and two from temperate regions (Buenos Aires City and San Bernardo) of Argentina. Eggs collected in the field were raised in three experimental colonies. F1 eggs were acclimated for 7 days prior to immersion at 7.6 or 22°C (control eggs). Five immersion temperatures were tested: 7.6, 10.3, 11.8, 14.1 and 16°C (range of mean winter temperatures of the three localities). A second immersion at 22°C was performed 2 weeks later to assess the inhibition to hatch under favourable conditions. After the first immersion, we compared the proportions of hatched eggs and dead larvae among treatment levels, whereas after the second immersion we compared the hatching response among the three populations. The factors that most influenced the egg hatching response were the geographical origin of the populations and the immersion temperature, but not the acclimation temperature. The proportions of hatching and larval mortality at low temperatures were higher for Resistencia than for Buenos Aires and San Bernardo, whereas the hatching response at ambient temperature was lower for San Bernardo than for Buenos Aires and Resistencia. The results support the hypothesis that populations from colder regions show an adaptive inhibition of egg hatching.

Dolomite-zirconia reaction sintered bonded coarse magnesia ceramics: Effect of the bonding proportion Booth, Raul Fernando Nicolas; Stábile, Franco Matías; Bruni, Yesica Lorena; Gauna, Matias Roberto; Rendtorff Birrer, Nicolás Maximiliano Refractory ceramic materials were manufactured, mainly composed of magnesia grains (coarse and medium fraction) and CaZrO3/MgO as a binding phase produced from the reaction sintering between CaMg(CO3)2(dolomite) and m-ZrO2 (monoclinic zirconia), which constituted the finer fraction. Different relationships between the proportion and the size of the different aggregates were studied. The microstructure of the materials was characterized in terms of density, crystalline phases, grain phase distribution, and morphology. A combination of X-ray diffraction analysis and scanning electron microscopy with microanalysis was used. The mechanical behavior was determined in terms of the room temperature dynamic Young's modulus and the 3-point bending modulus of rupture (MOR) at room temperature. All the materials remained with porosities above 30%. The microstructure developed was similar between the sintered materials, characterized with MgO coarse grains bonded by CaZrO3/c-ZrO2phases, and dispersed irregularly shaped pores. The MOR was directly related to the finer fraction content in the composition, where a higher quantity of finer fraction resulted in a higher MOR.

Variability and effect sizes of intracranial current source density estimations during pain: Systematic review, experimental findings, and future perspectives Völker, Juan Manuel; Arguissain, Federico Gabriel; Kæseler Andersen, Ole; Biurrun Manresa, José Alberto Pain arises from the integration of sensory and cognitive processes in the brain, resulting in specific patterns of neural oscillations that can be characterized by measuring electrical brain activity. Current source density (CSD) estimation from low-resolution brain electromagnetic tomography (LORETA) and its standardized (sLORETA) and exact (eLORETA) variants, is a common approach to identify the spatiotemporal dynamics of the brain sources in physiological and pathological pain-related conditions. However, there is no consensus on the magnitude and variability of clinically or experimentally relevant effects for CSD estimations. Here, we systematically examined reports of sample size calculations and effect size estimations in all studies that included the keywords pain, and LORETA, sLORETA, or eLORETA in Scopus and PubMed. We also assessed the reliability of LORETA CSD estimations during non-painful and painful conditions to estimate hypothetical sample sizes for future experiments using CSD estimations. We found that none of the studies included in the systematic review reported sample size calculations, and less than 20% reported measures of central tendency and dispersion, which are necessary to estimate effect sizes. Based on these data and our experimental results, we determined that sample sizes commonly used in pain studies using CSD estimations are suitable to detect medium and large effect sizes in crossover designs and only large effects in parallel designs. These results provide a comprehensive summary of the effect sizes observed using LORETA in pain research, and this information can be used by clinicians and researchers to improve settings and designs of future pain studies.

¿Quiénes son los trigueños? Análisis de una categoría racial intersticial (Buenos Aires, 1810-1830) Guzman, Maria Florencia El término "trigueño" es una categoría intersticial y ambigua con la que fueron clasificados un importante porcentaje de soldados y reclutas de condición libre a partir de 1810.La investigación que se presenta tiene un doble propósito: por un lado, de comenzar a examinar del contenido histórico de la expresión trigueño, que hasta el momento no presenta una caracterización precisa, articulando la dimensión racial con otras de peso como la procedencia, el modo de vida y la instrucción. El segundo objetivo es el de enfatizar la ?posibilidad mestiza? que asume esta expresión, la cual matiza la idea del traslado estadístico de la población africana a esta categoría y remite invariablemente al estudio del mestizaje colonial y de las categorías raciales de la hibridez. Las fichas de "filiación" relativas a los reclutas que fueron militarizados entre 1810-1830, constituyen la fuente principal de la investigación las que puestas en diálogo con otros corpus documentales del temprano republicanismo posibilitarán una mayor comprensión de las lógicas de clasificación en tanto éstas revelan -o son indicios- de las políticas que crearon esos instrumentos y también de quienes las produjeron.

El Golfo San Jorge como área prioritaria de investigación, manejo y conservación en el marco de la Iniciativa Pampa Azul Dans, Silvana Laura; Cefarelli, Adrián Oscar; Galvan, David Edgardo; Góngora, María Eva; Martos, Patricia; Varisco, Martin Alejandro; Alvarez Colombo, Gustavo Luis; Blanc, Silvia; Bos, Patricio; Bovcon, Nelson Darío; Charo, Marcela; Cinquini, Mariano Enrique; Derisio, Carla María; Dogliotti, Ana Inés; Ferreyra, Gustavo Adolfo; Funes, Manuela; Giberto, Diego Agustin; Halm, Cristian; Hozbor, Constanza; Irigoyen, Alejo Joaquin; Lewis, Mirtha Noemi; Macchi, Gustavo Javier; Maenza, Reinaldo Agustín; Nocera, Ariadna Celina; Paparazzo, Flavio Emiliano; Parma, Ana María; Pisoni, Juan Pablo; Prario, Igor Sebastian; Sánchez, Noela Belén; Sastre, Viviana; Segura, Valeria Romina; Silva, Ricardo; Schiariti, Agustin; Temperoni, Brenda; Tonini, Mariano Hernan; Tolivia, Analía Alejandra; Trobbiani, Gastón Andres; Venerus, Leonardo Ariel; Vernet, María; Vinuesa, Julio Hector; Villanueva Gomila, Gabriela Lujan; Williams, Gabriela Noemí; Yorio, Pablo Martin; Zárate, Marcos Daniel El Golfo San Jorge (GSJ) fue incluido como una de las áreas geográficas prioritarias en el marco de la Iniciativa Pampa Azul por ser una de las regiones más productivas y con mayor diversidad del Mar Argentino. La región es clave en el ciclo de vida de los recursos pesqueros más importantes de Argentina y cuenta con áreas protegidas destinadas a la conservación de su biodiversidad y con un alto potencial para el desarrollo turístico. La jurisdicción del GSJ es compartida por las provincias de Chubut y Santa Cruz, mientras que las aguas adyacentes de plataforma están bajo jurisdicción nacional. Este carácter interjurisdiccional, sumado al gran número de instituciones involucradas en su estudio y gestión generan interesantes desafíos en materia de políticas de investigación y manejo. Este artículo pretende dar a conocer la importancia del GSJ, el conocimiento existente acerca del sistema, y la necesidad de construir, ejecutar y sostener un programa de investigación y monitoreo a largo plazo con un foco en los servicios que presta este ecosistema y los impactos de las actividades que allí se desarrollan. Los avances realizados en esa dirección son puestos en el contexto nacional y mundial, no solo por el conocimiento generado sino también por el logro de haber nucleado a varias instituciones del país dando inicio a un programa de investigación multidisciplinario con un enfoque ecosistémico, impulsado desde la iniciativa Pampa Azul.; San Jorge Gulf (GSJ) was included among Areas of priority by the National Initiative Pampa Azul since it is one of the most productive and diverse regions of the Argentine Sea. It is a key region for the life cycle of several species including most important fishery resources, the definition of protected areas of biodiversity conservation interest, and for a potential tourism development. This region is under provincial (Chubut and Santa Cruz Provinces) but also national jurisdiction, and several institutions are engaged in research as well management, so the area represents a challenge for research and management policies. The goal of this article is to acknowledge the importance of GSJ, to present the main results of ongoing research, and highlight the need of building, carrying on and sustaining a research and monitoring program in the long term, focusing on ecosystem services and human impacts. Advances are contextualized in national and international frameworks, not only due to the importance of new scientific knowledgement achieved, but also for the response and collaboration of several institutions to the need of constructing a multidisciplinary program with an Ecosystem Approach, requested by Pampa Azul.

Crítica política del concepto occidental moderno de género desde una perspectiva feminista descolonial e interseccional; A Political Critique of the Contemporary Western Notion of Gender from a Decolonial Intersectional Feminist Approach; Critica politica do conceito ocidental moderno de gênero desde uma perspectiva feminista decolonial e interseccional Parra, Valeria Fabiana Frente al pensamiento occidental moderno –en el que subyace una lógica dicotómica y jerárquica– argumento que la producción de conocimientos situada, inclusiva e interseccional, constituye una alternativa tanto epistemológica como política para descolonizar nuestros feminismos. Para ello, propongo trazar genealogías feministas desde el sur porque al centrarse en las experiencias vividas en nuestra región permiten mostrar el carácter situado de todo saber; y comprender la opresión desde una perspectiva interseccional.; Facing contemporary Western thinking –with an underlying dichotomic hierarchic rationale– I argue that situated, inclusive and intersectional knowledge production makes up both an epistemological and a political alternative to decolonize our feminisms. In tandem with this, I suggest to devise feminist genealogies from the South, as by centering in experiences lived in our region, they allow for displaying the situated nature of all and every learning and understand oppression from an intersectional point of view.; Diante o pensamento ocidental moderno – que sustenta uma lógica dicotómica e hierárquica– argumento que a produção de conhecimentos situada, inclusiva e interseccional constitui uma alternativa tanto epistemológica quanto politica para descolonizar nossos feminismos. Para isso, proponho traçar genealogias feministas desde o sul centradas nas experiências vividas em nossa região, assim, elas permitem mostrar o caráter situado de todo saber e compreender a opressão desde uma perspectiva interseccional.

Desarmando oleadas y trasplantes: El protestantismo histórico reconsiderado; Disarming waves and transplants: Historical Protestantism reconsidered Seiguer, Paula Este artículo plantea la necesidad de repensar los esquemas habituales que empleamos para caracterizar el derrotero de las iglesias protestantes históricas en la Argentina, y por extensión, en América Latina. Desde la publicación del trabajo seminal de Waldo Luis Villalpando, Christian Lalive D´Epinay y Dwain C. Epps, Las iglesias del trasplante, de 1970, se ha enfatizado la división entre iglesias migratorias y misioneras. Este planteo fue retomado y enriquecido por Hilario Wynarczyk y Pablo Semán en su artículo "Campo evangélico y pentecostalismo en la Argentina", de 1994, que describe cuatro vertientes u "oleadas" del protestantismo argentino, y que ha sido repetido en numerosas oportunidades. A la luz de los más recientes avances teóricos e históricos se pondrá en cuestión aquí tanto la existencia de "oleadas" homogéneas de iglesias que llegaron a la Argentina durante el siglo XIX y los inicios del siglo XX, y una visión demasiado lineal de su desarrollo, como la división entre iglesias inmigratorias e iglesias misioneras.; This article posits the need for rethinking the usual framework we employ to characterize the development of historical Protestant churches in Argentina and by extension in Latin America. Since the publishing of Waldo Luis Villalpando, Christian Lalive D'Epinay and Dwain C. Epps's seminal work, Las iglesias del trasplante, in 1970, the division between migrant and missionary churches has been emphasised. This schema was taken up and enriched by Hilario Wynarczyk and Pablo Semán in their article "Campo evangélico y pentecostalismo en la Argentina", of 1994, which describes four strands or "waves" of Argentine Protestantism, and has been restated multiple times. In the light of the most recent theoretical and historical advances both the existence of homogeneous "waves" of churches coming to Argentina during the 19th and the beginning of the 20th centuries, and a too-linear view of their development, and the division between migrant and missionary churches will be put into question here. The article also proposes that a less schematic approach would allow for a renewal of the questions on the conformation of the Evangelical field, and on the relations between different churches and the phenomenon of Pentecostalism

Masculinidades y subjetivización política en el movimiento obrero argentino a comienzos del siglo XX; Masculinities and processes of political subjectivization of the labour movement in Argentina at the beginning of the twentieth century Koppmann, Walter Ludovico El artículo analiza el proceso de construcción de las masculinidades obreras en la clase trabajadora de Buenos Aires durante las primeras décadas del siglo XX, valiéndose del estudio de caso de la industria de la madera y el mueble. Se identifican las líneas de demarcación del género mediante el análisis de los discursos, las prácticas y las formas de sociabilidad, utilizando la prensa obrera gremial como insumo principal. Dentro de este universo de sentidos, se estudia la intervención de las corrientes de izquierda (anarquistas, socialistas, sindicalistas revolucionarios) sobre los procesos de subjetivación política y organización sindical.; The article analyzes the process of construction of worker masculinities in the working class of Buenos Aires during the first decades of the twentieth century, using the case study of the wood and furniture industry. Gender demarcation lines are identified through the analysis of discourses, practices, and forms of sociability, using the union labor press as the main input. Within this universe of meanings, the intervention of left-wing currents (anarchists, socialists, revolutionary syndicalists) on the processes of political subjectivation and union organization was studied. Keywords: masculinities, working class, wood and furniture industry, union organization, Buenos Aires.

La "autogestión" en SEGBA: entramado conceptual de una experiencia singular (1964-1973) Scodeller, Gabriela Noemi El artículo analiza el entramado conceptual de la experiencia de “autogestión” desarrollada en SEGBA entre 1973 y 1976, argumentando que la misma se gestó en diálogo con los diversos modelos de gestión entonces disponibles a escala internacional y donde el caso yugoslavo circuló temprana y fuertemente por el imaginario lucifuercista. Busca advertir en qué clave la misma fue entonces discutida por sus protagonistas, lo cual permite descubrir una profunda reflexión al interior del Sindicato Luz y Fuerza Capital Federal en relación al tema de la participación, a la vez que muestra distintas concepciones en disputa al interior del sindicato que la puso en marcha. Para ello se observan los distintos viajes e intercambios de los dirigentes sindicales y técnicos vinculados al mismo, a través de su prensa sindical.

Moral y estrategia en la teoría social de Erving Goffman; Morality and strategy in Erving Goffman’s social theory Gonnet, Juan Pablo En la formulación de una teoría del orden social, frecuentemente se entiende que los componentes estratégicos y morales de la acción social constituyen fuerzas antagónicas. En este sentido, la teoría de la interacción de Erving Goffman, al abordar simultáneamente ambas dimensiones, ha sido descrita como ambigua, contradictoria e incluso complementaria. En este texto se sostiene que dichas interpretaciones resultan inadecuadas en tanto no dan cuenta del modo en el que Goffman redefine el vínculo entre moral y orden social. A partir de la reconstrucción de esta conceptualización, se pretende hacer comprensibles las interrelaciones que guardan los hechos normativos con el actuar estratégico.; In the development of a theory of social order, it is often understood that the moral and strategic dimensions of social action are opposite forces. Thus, Erving Goffman’s interaction theory, which simultaneously approaches both dimensions, has been described as ambiguous, contradictory and even complementary. In this article it is argued that these interpretations are inadequate, as they do not account for the way in which Goffman redefines the link between morality and social order. Starting from a reconstruction of this conceptualization, this paper purports to explain the relationships between normative facts and strategic action.

La relación entre los puntajes del Inventario de Comunicación Mac-Arthur Bates y la vulnerabilidad social en los primeros años de vida: una revisión sistemática; The relationship between Mac-Arthur Bates Communication Inventory scores and social vulnerability in the early years of life: a systematic review Gómez, Florencia N.; Sosa, Guadalupe; Castrillón, Diego; Morales, Leandro J.; Gago Galvagno, Lucas Gustavo Se entiende a la vulnerabilidad social como una variable multidimensional que involucra una combinación de eventos, rasgos y/o procesos que constituyen adversidades potenciales para ejercer los derechos humanos o alcanzar objetivos en la comunidad. Se ha observado que las habilidades lingüísticas, fuertemente ligadas al éxito académico, difieren según el nivel socioeconómico del contexto de crianza. Los Inventarios de Desarrollo Comunicativo de MacArthur Bates (CDI) son instrumentos que evalúan el desarrollo de las competencias comunicativas durante la primera infancia a través del reporte de un cuidador primario. El objetivo de la siguiente revisión sistemática será indagar las correlaciones entre el entorno socioeconómico y las competencias comunicativas, medidas con el CDI, en los primeros tres años de vida. Se encontraron diferencias respecto del desarrollo del habla, la comprensión y expresión del lenguaje en niños/as inmersos en contextos vulnerables, principalmente en aquellos infantes de entre 18 a 24 meses, previo a la inserción a la escolaridad formal. Se concluye que el CDI es un instrumento sensible a las diferencias socioeconómicas familiares, y que se deben realizar más estudios en culturas diversas y durante los primeros años de vida, para generar políticas públicas que logren paliar las diferencias en el desarrollo cognitivo infantil.; Social vulnerability is understood as a multidimensional variable that involves a combination of events, features and processes that enhance potential adversities against the compliance of human rights and the fulfillment of goals in the community. It has been proved that linguistic abilities, strongly related to academic achievement, differ depending on the socioeconomic level of the raising context. e MacArthur’Bates Communicative Development Inventories (CDI) is a tool that assesses the development of communicative competences during the early childhood based on the primary caregiver report. e aim of the following systematic review will be to find the correlations between the socioeconomic environment and the communicative competences, assessed with the CDI, in the first three years of life. e data analysis showed that low income children aged 18 - 24 months presented differences in both, their speech development, and their comprehensive / expressive language skills. It is concluded that the CDI is an assessment tool which is sensitive to the environment’s socioeconomic differences. In addition, more studies should be developed in diverse cultures and during the first years of life, in order to develop public policies that can alleviate the existing differences in infants’ cognitive development.

El archivo (sonoro) como proceso; The (Sound) Archive as a Process Garcia, Miguel Angel En los últimos años las prácticas asociadas a los archivos han sido objeto de críticas y redefiniciones por parte de varias disciplinas. Aunque se trata de un escenario sumamente ecléctico, las discusiones convergen en asignarle al archivo un carácter procesual, inestable e inacabado. Bajo esta nueva perspectiva, que en alguna medida renuncia a ver el archivo como un conjunto de documentos, una institución que acoge y administra los documentos o un edificio donde los documentos son albergados, el término ‘archivo’ está ampliando considerablemente su polisemia y, a la vez, tiende a convivir con expresiones y vocablos tales como ‘práctica archivística’, ‘archivación’, ‘archivalización’, an-archive, ‘multiverso archivístico’, ‘poética del archivo’, archivalterity y ‘anarchivismo’, entre otros. El propó­ sito del artículo consiste en presentar los lineamientos generales de esta perspectiva y sopesar sus alcances a partir de la observación de cómo un conjunto de grabaciones realizadas a principios del siglo XX en Tierra del Fuego, por Charles Wellington Furlong, fueron repro­ ducidas por diferentes tecnologías, interrogadas desde distintas disciplinas y teorías, y oídas bajo diferentes condiciones acústicas y disposiciones auditivas. La revisión del caso a la luz de la concepción procesual del archivo conduce, finalmente, a abrir una discusión entorno a la pregunta ¿qué almacena el archivo? y, más precisamente, ¿qué almacena el archivo sonoro?; In recent years, the practices associated with archives have been subject to crit­ icism and redefinition by various disciplines. Although it is a highly eclectic scenario, the discussions converge in assigning to the archive a processual, unstable and incomplete qual­ ity. Under this new perspective, which to some extent rejects seeing the archive as a set of documents, an institution that hosts and manages documents or a building where docu­ ments are housed, the term ‘archive’ is considerably expanding its polysemy and, at the same time, tends to coexist with expressions and words such as ‘archival practice’, ‘archivalization’, ‘an-archive’, ‘archival multiverse’, ‘poetics of the archive’, ‘archivalterity’ and ‘anarchivism’, among others. The purpose of the article is to present the general outlines of this perspective and to weigh its scope from the observation of how a set of recordings made in the early twentieth century in Tierra del Fuego, by Charles Wellington Furlong were reproduced with different technologies, interrogated from different disciplines and theories, and heard under different acoustic conditions and aural dispositions. The review of the case in the light of the processual conception of the archive leads, finally, to a discussion around the question: what does the archive store? and, more precisely, what does the sound archive store?
