Demócratas insatisfechos: un estudio sobre actitudes hacia la democracia en Córdoba (Argentina); Dissatisfied democrats: a study of democratic attitudes in Argentinian citizens Alonso, Daniela Rocío; Brussino, Silvina Alejandra; Civalero Gottero, Luciana María Este trabajo propone un abordaje de las actitudes ciudadanas hacia la democracia y el rol de aspectos psicosociales en su análisis. De modo específico, se estudiaron las diferencias en las actitudes hacia la democracia respecto a tres dimensiones relacionadas: preferencia por el régimen político democrático, valoración de la democracia como ideal y satisfacción con el funcionamiento de la democracia. Además, se analizó la contribución de los valores psicosociales, el autoposicionamiento ideológico, la tolerancia a la corrupción política, evaluación de los actores políticos, participación política y aspectos sociodemográficos a la explicación de estas dimensiones de las actitudes hacia la democracia. Para ello, se tomó una muestra de 252 ciudadanos de Córdoba (AR), de entre 18 y 65 años, a través de un muestro cuotificado por edad, sexo y nivel socioeconómico. Los datos se recogieron mediante un cuestionario cerrado en formato papel y, para su análisis, se hicieron pruebas de diferencia de medias y análisis de regresión múltiple. Los resultados permitieron dar cuenta de que los ciudadanos realizan evaluaciones diferenciales de la democracia como sistema político abstracto y de su capacidad de brindar resultados deseables. Se discute el rol de las variables estudiadas en las evaluaciones sobre democracia, destacando la importancia de aspectos ideológicos y normativos.; This article access citizens’ attitudes towards democracy and the role that psycho-social aspects play on their explanation. Specifically, differences in attitudes towards democracy based on three related dimensions are studied: preference for a democratic political system, evaluation of democracy as an ideal and satisfaction with the functioning of democracy. In addition, we address the contribution of psychosocial values, ideology, tolerance of political corruption, evaluation of political actors, political participation and socio-demographic aspects to the explanation of these three dimensions of attitudes toward democracy. We selected a sample of 252 citizens of Córdoba (AR), between 18 and 65 years old, through sampling with age, sex and socioeconomic status quotification. Data was collected through the application of a closed questionnaire and mean difference tests and multiple regression analysis were performed. The results evidenced that citizens make differential assessments of democracy as an ideal and about its ability to provide desirable results. The role of the variables studied in relation to the different assessments of democracy is discussed, highlighting the importance of ideological and normative aspects.

Membrane-shed vesicles from the parasite Trichomonas vaginalis: characterization and their association with cell interaction Nievas, Yésica Romina; Cóceres, Verónica Mabel; Midlej, Victor; de Souza, Wanderley; Benchimol, Marlene; Pereira Neves, Antonio; Vashisht, Ajay A.; Wohlschlegel, James A.; Johnson, Patricia J.; de Miguel, Natalia Trichomonas vaginalis is a common sexually transmitted parasite that colonizes the human urogenital tract, where it remains extracellular and adheres to epithelial cells. Infections range from asymptomatic to highly inflammatory, depending on the host and the parasite strain. Despite the serious consequences associated with trichomoniasis disease, little is known about parasite or host factors involved in attachment of the parasite-to-host epithelial cells. Here, we report the identification of microvesicle-like structures (MVs) released by T. vaginalis. MVs are considered universal transport vehicles for intercellular communication as they can incorporate peptides, proteins, lipids, miRNA, and mRNA, all of which can be transferred to target cells through receptor–ligand interactions, fusion with the cell membrane, and delivery of a functional cargo to the cytoplasm of the target cell. In the present study, we demonstrated that T. vaginalis release MVs from the plasma and the flagellar membranes of the parasite. We performed proteomic profiling of these structures demonstrating that they possess physical characteristics similar to mammalian extracellular vesicles and might be selectively charged with specific protein content. In addition, we demonstrated that viable T. vaginalis parasites release large vesicles (LVs), membrane structures larger than 1 µm that are able to interact with other parasites and with the host cell. Finally, we show that both populations of vesicles present on the surface of T vaginalis are induced in the presence of host cells, consistent with a role in modulating cell interactions.

Comments on Digital Current Control in a Rotating Reference Frame-Part I: System Modeling and the Discrete Time-Domain Current Controller With Improved Decoupling Capabilities Busada, Claudio Alberto; Gómez Jorge, Sebastián; Solsona, Jorge Alberto A recent paper presents a discrete time model in a rotating dq reference frame of an R-L filter, and its current control. The purpose of this note is: 1) To show that the discrete model presented in the paper behaves differently to the sampled continuous time model of the plant, formulated in the stationary reference frame. 2) To find the proper discretization of the plant in dq coordinates. 3) To verify that there is cross coupling between axis d and q in the closed loop system if the original model is used, and that this coupling is not present when using the model found in this note. In the note it is verified that having a precise model of the plant allows to fulfill the control objective of obtaining the complete decoupling between axis.

Effect of milk production on reproductive performance in dairy herds Rearte, R.; LeBlanc, S. J.; Corva, S. G.; de la Sota, Rodolfo Luzbel; Lacau, Isabel María; Giuliodori, M. The objective of the present study was to assess the relationship between individual cow milk yield and fertility, accounting for the contextual effect of the herd. A dataset including 657,968 lactations from 677 dairy herds in Argentina from 2001 to 2012 was used. The odds of pregnancy by 100 DIM were assessed by a multilevel logistic model (with cow as the first and herd as the second hierarchical level), and time to pregnancy by a proportional hazards regression model. Multilevel logistic models included the fixed effects of milk yield by 80 DIM, parity, year and calving season at cow level and quartiles of herd milk yield by 80 DIM as a contextual effect. The proportional hazards model included the effect of daily milk yield as time dependent variable and herd-level milk yield as stratification variable. Cows producing 1 SD (400 kg) over the mean milk yield of their herd had 1.0 percentage points lower pregnancy by 100 DIM (from 31.4% to 30.4%, odds ratio (OR) = 0.942) when in herds in the top quartile of milk yield, whereas they increased 0.4 percentage points (from 27.9 to 28.3%) when in herds in the lowest quartile of milk yield. Only 4% of the observed variation in pregnancy by 100 DIM was explained by the random effect of the herd. Similarly, cows producing 1 SD (8 kg/d) greater than the herd daily milk had 1.3% lower hazard of pregnancy (hazard ratio (HR) = 0.987) at 63 DIM in herds in the top quartile of milk yield whereas they had 14.8% higher hazard (HR = 1.148) in herds in the lowest quartile of milk yield. The magnitude of the negative association between the cow´s daily milk yield and the hazard of pregnancy increased with DIM.In conclusion, the relationship between milk yield and reproductive performance is statistically significant but the effect size is practically small, it is modulated by herd productivity.

Anomalous reduction in the long-time flux creep relaxation in superconducting Ca10(Pt4As8)((Fe1-xPt x )2As2)5 (x ≈ 0.05) single crystals Haberkorn, Nestor Fabian; Huang, Silu; Jin, R. We report the vortex dynamics of superconducting a Ca10(Pt4As8)((Fe1-xPtx)2As2)5 (x ≈ 0.05) single crystal with T c = 26 K investigated by performing magnetic measurements. The field dependence of the magnetization displays a second peak (SPM), typically related to a crossover between elastic and plastic vortex relaxation in a weak pinning scenario. Long-time flux creep relaxation measurements for fields smaller that of the SPM show that the vortex dynamics can be separated in two different regions. For magnetic fields smaller than the lower end of the SPM, glassy relaxation (with a characteristic glassy exponent μ) is observed. For magnetic fields between the lower end and the SPM, the flux creep rate decreases systematically to values below to the ones predicted by the collective theory. This effect can be understood by considering a stable vortex lattice configuration. As the field position of the SPM can be adjusted by modifying the quenched potential, our results suggest that extremely low flux creep relaxation rate may be tuned in many other superconducting materials.

Structural and vibrational study on the acid, hexa-hydrated and anhydrous trisodic salts of antiviral drug Foscarnet Iramain, Maximiliano Alberto; Brandan, Silvia Antonia The structural and vibrational properties of acid species, hexa-hydrated and anhydrous trisodic salts of antiviral drug foscarnetin gas phase and in aqueous solution have been studied in this work by using the hybrid B3LYP method with the 6-31G* and6-311++G** basis sets. The properties in solution were carried out with the self consistent reaction force (SCRF) method by usingthe integral equation formalism variant polarised continuum (IEFPCM) and SD models while the complete vibrational assignmentsfor those three species were performed in both media by using the experimental available infrared spectrum of hexa-hydratedtrisodic salt and the scaled quantum mechanical force field (SQMFF) methodology. The natural bond orbital (NBO) studies suggestthat the hexa-hydrated salt in solution is most stable than the anhydrous one in the same medium but in gas phases the anhydroussalt shows a higher stability in solution. The atoms in molecules (AIM) analyses have revealed the ionic characteristics of the O---Na bonds in both salts supporting the higher stability of the hexa-hydrated salt in solution. The evaluation of the frontier orbitalsshow that the anhydrous salt is the most reactive species in solution, as supported by its higher solvation energy and volumevariation. Apparently, the presences of phosphate group in foscarnet probably increase its activity when it is used as drug. Theexperimental infrared bands observed in the hexa-hydrated species at 1059 and 983 cm-1 are clearly attributed to the stretchingmodes of phosphate group while the strong bands at 1445 and 1333 cm-1 are associated to the stretching modes of carboxylategroup. In addition, the force constants for the carboxylate and phosphate groups are reported.

Mercury in the feathers of bird scavengers from two areas of patagonia (Argentina) under the influence of different anthropogenic activities: A preliminary study Di Marzio, Alessandro; Gómez Ramírez, Pilar; Barbar, Facundo; Lambertucci, Sergio Agustin; García Fernández, Antonio Juan; Martínez López, Emma Mercury (Hg) is a global pollutant that bioaccumulates and biomagnifies in food chains and is associated with adverse effects in both humans and wildlife.We used feather samples from bird scavengers to evaluate Hg concentrations in two different areas of Northern Patagonia. Hg concentrations were analyzed in feathers obtained from turkey vultures (Cathartes aura), Black Vultures (Coragyps atratus), and southern crested caracaras (Caracara plancus) from the two areas of Northern Patagonia (Argentina): Bariloche and El Valle. Hg was detected in all the samples analyzed, but the concentrations can be considered low for the three species in both sampling areas. The mean concentration of Hg in Bariloche was 0.22 ± 0.16 mg/kg dry weight (d.w.) in black vulture, 0.13 ± 0.06 mg/kg d.w. in turkey vulture, and 0.13 ± 0.09 mg/kg d.w. in southern crested caracara; in El Valle, the mean concentration of Hg was 1.02 ± 0.89 mg/kg d.w. in black vulture, 0.53 ± 0.82 mg/kg d.w. in turkey vulture, and 0.54 ± 0.74 mg/kg d.w. in southern crested caracara. Hg concentrations in feathers were explained by the sampling area but not by the species. The concentrations of Hg contamination were comparable to those obtained in other studies of terrestrial raptors and aquatic bioindicator raptors. The species of the present study occur throughout much of North and South America. Thus, they may be appropriate bioindicators across the species’ range, which is particularly useful as a surrogate, especially in distribution areas shared with endangered scavengers such as the California condor (Gymnopsys californianus) and the Andean Condor (Vultur gryphus).

Drivers of cyanobacteria dominance, composition and nitrogen fixing behavior in a shallow lake with alternative regimes in time and space, Laguna del Sauce (Maldonado, Uruguay) González Madina, Lucía; Pacheco, Juan Pablo; Yema, Lilen; de Tezanos Pinto, Paula; Levrini, Paula; Clemente, Juan Pablo; Crisci, Carolina; Lagomarsino, Juan José; Méndez, Gustavo; Fosalba, Claudia; Goyenola, Guillermo; Mazzeo, Néstor Laguna del Sauce, one of the main drinking water sources in Uruguay, is an eutrophic shallow lake with high temporal variation of inorganic turbidity caused by extreme wind events. During low turbidity periods, high phytoplankton biomass can be reached, frequently associated to cyanobacteria blooms, which can cause interferences in the water supply. In this study, we assessed the environmental drivers of cyanobacteria dominance, composition, and nitrogen-fixation behavior. For this, we analyzed the spatial and temporal phytoplankton composition, physical and chemical variables performing weekly samplings during two summers: 2015?2016 and 2016?2017. When inorganic turbidity was high (above 30 NTU), phytoplankton biomass was controlled, below this threshold, temperature, secchi depth and nutrients played key factors controlling cyanobacteria biomass and composition. Blooms of N2-fixing cyanobacteria (Dolichospermum crassum, Aphanizomenon gracile, and Cuspidothrix issatschenkoi) were promoted by low N:P ratios (average 11.5) and wide TN range (286?1300 µg l−1). Non-heterocystous cyanobacteria blooms occurred above TN 1000?1200 µg l−1. The N2-fixing behavior (heterocytes:vegetative cell ratio) depended on TN, it was highest at low TN (< 700 µg l−1) but null above ca. 1000 µg l−1. While low inorganic turbidity allowed cyanobacteria blooms in Laguna del Sauce, its composition and N2-fixation behavior depended on the TN and TP levels.

Heidegger y la concepción del «espacio-tiempo» en la teoría de la relatividad especial; Heidegger and the conception of «space-Time» in the special relativity theory Simesen de Bielke, Martín Miguel Heidegger sostiene que la relatividad no ha superado las limitaciones de la metafísica tradicional porque Einstein aún concibe el tiempo como parámetro, escala, serie irreversible de instantes homogéneos y como espacio, lo mismo que Aristóteles en su Física. En este artículo, se discute con Heidegger la noción de tiempo en la relatividad especial, particularmente el sentido y alcance de la «espacialización» del tiempo. Se sugiere que la relatividad de espacio y tiempo se pueden interpretar por medio del concepto de «analogía», como proporción y mediación entre espacio y tiempo.; Heidegger states that the relativity has not overcome the limitations of the traditional Metaphysics, because Einstein still conceives time as a parameter, as scale, as an irreversible series of homogeneous instants and as space, like Aristotle does in Physics. In this paper, it will be discussed with Heidegger the notion of time in the special theory of relativity, particularly the sense and scope of the «spatialization» of time. It is suggested that the relativity of space and time can be interpreted, by means of the concept of ‘analogy’, as proportion and mediation between time and space.

Stable Matching with Double Infinity of Workers and Firms Fuentes, Matías; Tohmé, Fernando Abel In this paper we analyze the existence of stable matchings in a two-sided large market in which workers are assigned to firms. The market has a continuum of workers while the set of firms is countably infinite. We show that, under certain reasonable assumptions on the preference correspondences, stable matchings not only exist but are also Pareto optimal.

Utilización de Omega 3 como alternativa terapéutica para el Síndrome de Ojo Seco en pacientes con glaucoma; Use of Omega 3 as a therapeutic alternative for Dry Eye Syndrome in Glaucoma Patients Andreoli, Agostina B.; Gomez Demmel, Eduardo F.; Tartara, Luis Ignacio Introducción: El objetivo del estudio fue determinar los cambios producidos en la superficie ocular mediante la administración oral de ácidos grasos (Omega 3) en pacientes bajo tratamiento crónico de glaucoma. Materiales y Métodos: investigación clínica no controlada, prospectiva y longitudinal realizada en pacientes con diagnóstico de glaucoma bajo tratamiento tópico antiglaucomatoso atendidos entre marzo y noviembre de 2016 en el Servicio de Oftalmología del Hospital Privado de Córdoba-Argentina. A los pacientes seleccionados (n=7) se les indicó la administración de una cápsula diaria de FITO CHIA CAPS (Omega 3) de ELEA® durante dos meses y se les realizaron controles (cuatro) mensuales. A todos y cada uno de los test se le asignó un valor cuantitativo para poder realizar el análisis estadístico correspondiente. Análisis estadístico: Se realizó test t de Student dependiente para muestras apareada (p igual o menor a 0,05) Resultados: Se observó una mejoría progresiva del tiempo de ruptura de la película precorneal (BUT) -en inglés tear break up time- y del test de Schirmer en los cuatro controles. En el caso de los test de fluoresceína y Rosa de Bengala se constató una mejoría marcada (p<0,05) en los primeros controles, pero cuando se retiró la medicación la curva evidenció un deterioro. Caso similar mostró el aspecto de la hiperemia conjuntival. En la prueba subjetiva (OSDI) siempre se constató mejoría progresiva. Conclusión: el tratamiento con Omega 3 mejora considerablemente la superficie ocular, tanto objetiva como subjetivamente en pacientes tratados por glaucoma, permitiendo así disminuir el uso de tratamientos tópicos crónicos.; Introduction: To determine changes in the ocular surface by the oral administration of fatty acids (Omega 3) in patients under chronic treatment of glaucoma. Materials and Methods: not Controlled, prospective and longitudinal clinical investigation performed in patients with glaucoma under topical antiglaucomatous treatment attended between March and November of 2016 at the Ophthalmology Service of the Hospital Privado of Córdoba-Argentina; Patients selected (n = 7) were given a daily FITO CHIA CAPS (Omega 3) capsule of ELEA® for two months and were given monthly (four) controls. All tests were assigned a quantitative value to perform the corresponding statistical analysis. Statistical analysis: We performed Student’s t-test for paired samples (p ≤ 0.05) Results: Progressive improvement of the BUT and the Schirmer test was observed in the four controls. In the case of the Fluorescein and Rose of Bengal tests, a marked improvement (p <0.05) was observed in the first controls, but when the medication was withdrawn the curve showed a deterioration. A similar case showed the appearance of the conjunctiva. The subjective test (OSDI) was always found progressive improvement. Conclusion: Treatment with Omega 3 significantly improves the ocular surface, both objectively and subjectively in patients treated by glaucoma, thus allowing to reduce the use of chronic topical treatments.

Periferia de la ciudad, entre la segregación urbana y la agricultura extensiva: caso Ituzaingó anexo, Córdoba, Argentina; City’s periphery, between urban segregation and extensive agriculture: case Ituzaingó anexo, Córdoba, Argentina Vanoli, Fernando Nicolas El barrio Ituzaingó Anexo está ubicado en la periferia sureste de la ciudad de Córdoba. Hace dieciséis años, la lucha de un grupo de madres visibilizó el conflicto ambiental que aún viven. Tal hecho,se hizo evidente al identificar enfermedades y muertes causadas por los efectos ambientales de los agrotóxicos en la producción de soja transgénica. En este trabajo, nos preguntamos de qué manera quienes deciden sobre la ciudad también son responsables de los daños ambientales producidos en este sector de la sociedad, a partir de comprender la relación del barrio con la configuración de la ciudad. Para esto, analizamos el surgimiento de Ituzaingó Anexo como barrio obrero en la expansión industrial de la ciudad y posteriormente el inicio del modelo productivo de agricultura intensiva. Haciendo énfasis en la incompatibilidad de usos habilitados por la zonificación en la planificación de la ciudad, y los efectos de segregación urbana y ambiental.; The Ituzaingó Anexo neighborhood is located on the Córdoba’s city southeast periphery. Sixteen years ago, the struggle of a mother’s group made visible the environmental conflict that they still live through. This fact became evident when they identified diseases and deaths caused by the environmental effects ofagrotoxics in the production of transgenic soybeans. In this work, we wonder how those who decide about the city are also responsible for the environmental damage produced in this sector of society, understanding the relationship of the neighborhood with the configuration of the city. In this way, we analyze the creation of Ituzaingó Anexo as a working class neighborhood in the industrial expansion of the city and later the beginning of the productive model of expansive agriculture. Emphasizing the incompatibility of uses enabled by zoning in the planning of the city, and the effects of urban and environmental segregation.

Morfometría de la cuenca alta del río Colorado, Argentina; Morphometric of the Colorado River high basin, Argentina Aumassanne, Carolina; Gaspari, Fernanda Julia; Beget, María Eugenia; Sartor, Paolo Daniel; Oricchio, Patricio; Di Bella, Carlos Marcelo Las subcuencas del río Grande y del río Barrancas conforman la cuenca alta del río Colorado y la abastecen de agua a partir de la nieve que precipita en las altas cumbres. Conocer las características morfométricas y funcionales de una cuenca es esencial en estudios de hidrología y modelación del agua. El objetivo fue analizar e interpretar los parámetros e índices morfométricos de la cuenca alta del río Colorado, Argentina. La metodología aplicada se basó en establecer y analizar los parámetros morfométricos mediante el uso de Sistemas de Información Geográfica y planillas de cálculo, a partir de un modelo digital de elevación. La longitud del río Grande es tres veces superior a la del Barrancas, con un área de drenaje que sigue la misma relación. Según el Coeficiente de Gravelius ambas subcuencas son similares en su forma, rectangular oblonga. Además, poseen la mitad de su superficie entre los 1.500 y 2.500 m.s.n.m., con pendientes predominantes de 0 a 15°. En cuanto a la orientación el 54 % de las laderas están orientadas al sur en ambos casos. El río Barrancas posee mayor desnivel entre naciente y desembocadura, en un área drenada menor. Este estudio ofrece importante información de base para posteriores investigaciones de modelado de la dinámica espacio temporal del caudal en la cuenca.; The Grande and Barrancas Rivers watersheds conform the upper basin of the Colorado River. They provide discharge from snow precipitated in the high mountain peaks. Morphometric and functional characteristics analysis of a basin is elementary in hydrology and modeling approach. The aim of this work was to analyze and interpret the morphometric parameters and derived indices of the upper basin of the Colorado River, Argentina. Parameters quantification and analysis were based on a digital elevation model and Geographic Information Systems. Length of the Grande River is three times greater than Barrancas River ones, with a drainage area that follows the same relationship. Gravelius coefficients evidenced similarities in watershed shapes, both rectangled-oblongued. Both watersheds have a half of their area between 1500 and 2500 m.a.s.l., with predominant slopes between 0 and 15º. In both cases, 54% of slopes are orientated to south direction, meaning predominantly shady. Barrancas River has a greater difference between the source and the mouth, having a smaller drained area. Results from this study offers an important source of base information to further research and modeling spatio-temporal dynamics of flow of River basin.

Psicología Comunitaria Positiva y Resiliencia Comunitaria: una propuesta de instrumento; Positive Community Psychology and Community Resilience: a proposal for an instrument; Psicologia Comunitária Positiva e Resiliência Comunitária: uma proposta de um instrumento Alzugaray, Claudia; Basabe, Norma; Muratori, Marcela; García, F.; Mateos Pérez, E. La resiliencia psicológica, que está suscitando un creciente interés en las últimas décadas, centra su atención en la forma en que individuos y grupos enfrentan exitosamente situaciones adversas. Desde la Psicología Comunitaria, el término resiliencia se ha utilizado para describir a comunidades que se han visto afectadas por catástrofes naturales y de violencia política. Este estudio propone un constructo multidimensional de Resiliencia Comunitaria (RC) para evaluar la percepción de los miembros de una comunidad sobre las capacidades de respuesta de la colectividad. En la primera fase del estudio, se analiza la validez de contenido a través del acuerdo inter-jueces para establecer los atributos y proponer una escala de medida. En una segunda fase, se constata la dimensionalidad y consistencia interna de las dimensiones de la RC y sus correlatos psicosociales. Posteriormente, se prueba la escala en dos países, Chile y Argentina, mediante un total de tres estudios (N = 1633; 54.6 % mujeres; edades entre 15 y 84 años, M = 26.47, DT = 18.99). Los resultados apoyan la existencia de tres dimensiones, Regulación emocional (RE), Capital y bienestar social (CBS) y Eficacia colectiva (EC), en dos versiones de la escala (RC51 y RC12 ítems), así como su consistencia interna. Además, se confirma la validez convergente y divergente. Finalmente, se discute la relación de la RC con las facetas del bienestar subjetivo individual, social y el clima socioemocional de la comunidad.; Psychological resilience has raised a growing interest in the last decades. It centers the attention in the way individuals and groups successfully face adverse situations. From Community Psychology, the concept of resilience it has been used to describe communities that have been affected by natural catastrophes and political violence. In order to evaluate the perception about the capacity of answering community members have, this study proposed a multidimensional construct of Community Resilience. In the first phase of the study it is analyzed its content validity through interrater agreement to stablish the features and propose a scale. In a second phase, its dimensionality and the consistency of its dimensions is verified, as well as its psychosocial correlates. Then, the scale is tested in two countries (Chile and Argentina) in three studies (N = 1633; 54.6% women; age range from 15 to 84 years, M = 26.47, SD = 18.99). Results support the existence of three dimensions of Emotional Regulation, Social Capital and Well-being, and Collective Efficacy in two versions of the scale (i.e., 51- and 12-item scales) and their interterm consistency. Likewise, its convergent and divergent validity is confirmed. Finally, it is discussed CR’s relationship with individual and social subjective wellbeing, and the community’s socio-emotional climate.; A resiliência psicológica tem suscitado um interesse crescente nas últimas décadas. Centra sua atenção na forma pela qual os indivíduos e os grupo enfrentam com êxito situações adversas. A partir da Psicologia Comunitária vem sendo utilizada para descrever as comunidades que foram afetadas por catástrofes naturais e por violência política. Propõe-se um construto multidimensional de Resiliência Comunitária (RC) para avaliar a percepção dos membros de uma comunidade em relação as capacidades de resposta da coletividade. O estudo analisa a validade do conteúdo através de um acordo inter-juízes para estabelecer os atributos e propor uma escala de medição. Em uma segunda fase constata-se a dimensionalidade e consistência interna das dimensões da RC, assim como suas correlações psicossociais. A escala é provada em dois países, Chile e Argentina, e são realizados 3 estudos (N = 1633; idade média M = 26,47 DT = 18.99; 45,6% mulheres). Os resultados apoiam três dimensões: Regulação emocional, Capital e Bem-estar Social; Eficácia coletiva em duas versões da escala (51 e 12 itens) e sua consistência interna. São confirmadas a validez convergente e divergente. Discute-se a relação da RC com as facetas do bem-estar subjetivo individual, social e o clima sócio emocional da comunidade.

Representaciones de la muerte: la migración española a través de sus edificios funerarios; Death representations: the spanish migration through their funeral buildings Castiglione, María Celeste El presente trabajo es un recorrido a través de la trayectoria migratoria de españoles en la zona fértil y llana del litoral pampeano, de fines del siglo XIX a mediados del siglo XX. De esta vasta historia se eligió tomar un aspecto poco investigado de la vida cotidiana e institucional: las manifestaciones funerarias practicadas por parte de esta comunidad, para ubicar a sus muertos, conmemorar el pasaje y recordar a los difuntos. En este contexto, resulta fundamental estudiar a las Asociaciones de Socorros Mutuos y su rol en la tramitación de la muerte de los connacionales, al otro lado del océano.; The present work is a route through the Spanish migration's route on the fertile and smooth surface of the litoral pampeano, starting on the end of the XIX century until the middle of the XX century. From all this vast history, we decided to take a barely investigated side of the daily and institutional life: the funerary manifestation practiced by this community, to place their dead ones, commemorate the pass and remember the deceased. On this context, it's fundamental to study the Mutual Help Associations and their role on the death's processing to the Nationals on the other side of the ocean

High neutrophil to lymphocyte ratio and decreased CD69+NK cells represent a phenotype of high risk in early-stage breast cancer patients Mandó, Pablo; Rizzo, Manglio Miguel; Roberti, María Paula; Juliá, Estefanía Paula; Pampena, María Betina; de la Puente, Constanza Pérez; Loza, Carlos Martín; Ponce, Carolina; Nadal, Jorge; Coló, Federico Andres; Mordoh, José; Levy, Estrella Mariel Purpose: Breast cancer (BC) is a highly heterogeneous disease presenting a broad range of clinical and molecular characteristics. In the past years, a growing body of evidence demonstrated that immune response plays a significant role in cancer outcome. However, immune prognostic markers are not completely validated in clinical practice in BC patients. Materials and methods: With the aim to characterize immune features, several parameters were analyzed in peripheral blood at diagnosis of 85 nonmetastatic BC patients between April 2011 and July 2014. Results: With a median follow-up of 38.6 months, peripheral blood analysis of BC patients (stages I, II, and III) showed that total lymphocyte and T lymphocyte counts were augmented in nonrelapsed patients. Also, a higher neutrophil-to-lymphocytes ratio was associated with prolonged disease-free survival. Natural killer cell receptor analysis revealed that early activation receptor CD69 was associated with a better outcome. Conclusion: This preliminary evidence is in accordance with the concept of immune surveillance. We suggest an “immune phenotype” that provides relevant prognostic information in early-stage BC patients and which could be useful in the decision-making process.

El Estado y la ficción televisiva: luces y sombras de una política de fomento Rivero, Ezequiel Alexander La producción de contenidos de ficción en Argentina como en otros lugares de la región estuvo históricamente caracterizada por la centralización geográfica en unos pocos centros urbanos. Desde 2009 el Estado Nacional introdujo una novedad mediante un conjunto de líneas de fomento público para la producción federal de contenidos, con el objetivo de diversificar los actores involucrados en esta actividad. No obstante, la experiencia tal como fue concebida, apenas superaría el lustro, y hacia fines de 2015 las políticas de comunicación restauraron el estado de cosas previo a la sanción de la LSCA, dejando, una vez más, la producción de ficción seriada casi exclusivamente en manos privadas. En base a datos empíricos recopilados por Obitel durante seis años, este artículo analiza los logros y limitaciones de la intervención estatal en el mercado de la ficción, en vistas a una evaluación de esta iniciativa pública y su valorización como política industrial y cultural. A su vez, se sitúan los planes de fomento en la intersección con la crisis productiva preexistente de la industria local de ficción.

'Lento' y 'un poco' como marcadores de atenuación en español paraguayo: Una mirada contrastiva con el español rioplatense; An analysis of "lento" and "un poco" as attenuative markers in paraguayan spanish, contrasted with rioplatense spanish Kornfeld, Laura Malena; Avellana, Alicia Mariana Este trabajo se propone caracterizar desde el punto de vista de la gramática generativa dos expresiones ligadas con el modo que aparecen en el español en contacto con guaraní (en particular de Paraguay): lento y un poco, a las que ponemos en relación con recursos análogos utilizados en el español rioplatense y en el guaraní. Exploramos en este trabajo la posibilidad de analizar ambos elementos como ‘atenuadores’, que la bibliografía pragmático-gramatical describe como elementos que se utilizan para mitigar o relativizar el impacto de las afirmaciones, en una estrategia propia de la cortesía (cfr. Caffi, 1999), o bien que “desactivan” la fuerza ilocutiva de un acto (Landone, 2009) y, sirven, pragmáticamente, para regular la relación interpersonal y social entre interlocutores. Se defiende aquí la hipótesis de que la noción de atenuación no puede ser subsumida en otros rasgos gramaticales, como los valores de posibilidad o aproximación, dentro del modo epistémico, y que puede integrarse en un análisis de corte generativo y, en particular, en el análisis cartográfico resumido en Cinque & Rizzi (2016), complementado por los aportes de la Morfología Distribuida sobre las proyecciones categoriales Sv, Sa, Sn (Marantz, 2001).; The purpose of this paper is to characterize, from the perspective of generative grammar, two expressions associated with mood that appear in Spanish in contact with Guarani (especially in Paraguay): lento and un poco, which are correlated with similar forms used in Rioplatense Spanish and in Guarani. In particular, we explore the possibility of analysing both elements as ‘attenuators’, which are described by the pragmatic-grammatical literature as elements that are used to mitigate or relativize the impact of the assertions in a specific strategy of politeness (cfr. Caffi 1999), or to deactivate the illocutive force of an act (Landone 2009). We believe that the notion of attenuation cannot be subsumed into other grammatical features, as ‘possibility’ or ‘approximation’, both related to the epistemic mood, and that it can be integrated in a generative analysis, in particular, in the cartographic analysis summarized in Cinque & Rizzi (2016), combined with the proposal of the categorial projections Sv, Sa, Sn in the framework of Distributed Morphology (cf. Marantz 2001).

Patrones de correlación de fluencias semánticas y fonológicas en niños en edad escolar; Correlational patterns in semantic and phonological fluency in school aged children Fumagalli, Julieta Carolina; Soriano, Federico Gonzalo; Shalóm, Diego Edgar; Barreyro, Juan Pablo; Martínez Cuitiño Carricaburo, María Macarena Las tareas de fluidez verbal semántica (FVS) y fluidez verbal fonológica (FVF) son medidas sensibles para detectar y diagnosticar diversas patologías tanto en la población adulta como en la infantil. Dado que las tareas de FVS y FVF permiten detectar problemas específicos de determinadas facultades lingüís­ticas o cognitivas, el objetivo de este trabajo es indagar las posibles relacio­nes existentes entre FVS y FVF en una población de niños argentinos de nivel escolar primario de 3°, 5° y 7° grado y edades comprendidas entre los 8 y 12 años. Los 86 niños participantes respondieron a una tarea de FVS en la que se evaluaron cinco categorías (animales, partes del cuerpo, medios de trans­portes, ropa e instrumentos musicales) y una tarea de FVF en la que respon­dieron a los fonemas /f/, /a/, /s/. Se realizó un análisis de correlaciones cuyo resultado muestra que existe una asociación de mediana intensidad entre ambas tareas. Además, se llevaron a cabo un análisis factorial exploratorio y uno confirmatorio, que detectaron dos factores diferenciados: un factor verbal semántico y un factor verbal fonológico. Los resultados obtenidos muestran que los procesos fonológicos y semánticos se encuentran diferenciados desde edades tempranas, aunque por su correlación es posible concluir que ambos procesos confluyen en un mismo almacén de búsqueda en la memoria verbal.; Semantic verbal fluency tasks (SVF) and phonological verbal fluency tasks (PVF) are highly sensitive measures used to detect and diagnose different pathologies in adult and child populations. The results of numerous investigations point out differential performances between these two tasks both in adults and children. Based on this evidence, we intend to identify the possible connections between SVF and PVF in a group of Argentinian children aged 8 to 12 years old who attended to 3 rd , 5 th and 7 th school primary levels. Participants answered to a SVF task which tested five categories (animals and body parts for living things and transports, cloth and musical instruments for inanimate objects domain) and a PVF task where the phonemes /f, a, s/ were assessed. A correlations analysis was carried out. The result showed there is a mild association between both tasks. In addition, an exploratory factor analysis and a confirmatory factor analysis were conducted. Two differential factors were detected: a semantic verbal factor and a phonological verbal factor. Our results show that phonological and semantic are different processes and function separately in early development, although due to their correlation it is possible to conclude that both processes converge in the same store in verbal memory.

Las Empresas Transnacionales: Un punto de encuentro para la Economía Política Internacional de América Latina; Transnational Corporations: A Meeting Point for the International Political Economy of Latin America Saguier, Marcelo; Ghiotto, Luciana Mabel El estudio de las Empresas Transnacionales (ETN) se encuentra en los orígenes de la Economía Política Internacional (EPI) en América Latina. El lugar preponderante de las ETN en las nuevas configuraciones de gobernanza económica internacional no ha sido explorado de forma sistemática en las investigaciones recientes de la EPI en la región. El objetivo del artículo es fundamentar la importancia de explorar las implicancias de las ETN en la gobernanza económica, así como visibilizar debates y aportes en esta temática que se han venido desarrollando al margen de los marcos de análisis de la EPI. Hacemos una revisión del lugar de las ETN en los procesos de construcción de reglas y prácticas de gobernanza internacional del comercio/inversiones y del ambiente. El argumento central es que las ETN no solo son actores económicos, sino que también actores “políticos” que intervienen en los procesos de reconfiguración de la relación Estado-mercado-naturaleza mediante la construcción de nuevos arreglos de gobernanza económica. La propuesta de volver a estudiar a las ETN ofrece un aporte a la reflexión sobre la identidad de la EPI de América Latina como un campo en construcción.; The study of transnational corporations (tncs) lies at the origin of the international political economy (ipe) field in Latin America. However, the preponderant place of tncs in the new configurations of international economic governance has not been systematically explored in recent ipe research in the region. The article makes the case for the importance of exploring the implications of tncs in economic governance and to engage with the debates and contributions that have remained on the margins of the epi framework. To do so, we reviewed the place of tncs in the processes of the construction of rules and practices of international governance in the areas of trade/investment and the environment. The argument is that tncs are not only economic actors, but also “political” actors that intervene in the process of reconfiguring the state-market-nature relationships through the construction of new economic governance arrangements. The article contributes to an ongoing reflection on the identity of epi in Latin America as a field under construction.
