Corporate governance attributes and listed SMES’ debt maturity Briozzo, Anahi Eugenia; Cardone-Riportella, Clara; García-Olalla, Myriam Purpose: This paper aims to develop a cross-country analysis of the similarities and differences in the debt maturity structure of listed SMEs from the point of view of corporate governance (CG) attributes in two different economic environments: an OECD (Spain) country and a non-OECD (Argentina) country. Design/methodology/approach: Using data from listed SMEs in the Argentinian SME segment (pooled data from 2012 to 2015) and 31 listed SMEs in the Spanish Mercado Alternativo Bursátil for growing firms (MAB_GE)(2014), bivariate and multivariate analyses are performed. Findings: Spanish firms with a higher ownership concentration and a large controlling shareholder have higher short-term liabilities (STL) ratios. Participation of women on the board has a negative relation with the STL ratio only for Spain. The participation of corporations in ownership and a Big4 auditor have a negative relation with the STL ratio for both countries. Practical implications: These results will help SME managers understand the effects of the application of good governance policies. The study also gives regulators a guideline to develop standards to assist in efficient borrowing in terms of seeking funding in alternative capital markets. Originality/value: First, the results provide evidence about the financial impact on the STL ratio of CG attributes in listed SME. Second, as far as the authors know, this is the first paper to analyse the CG attributes of listed SMEs in an OECD country and a non-OECD country. Third, the paper presents CG data derived from an ad hoc basis elaborated from different websites and databases.

Sentido y comunidad. La dimensión política del sentido común en Deleuze; Sense and Community. The Political Dimension of Common Sense in Deleuze Pachilla, Pablo Nicolás En el presente artículo se procurará subrayar la dimensión política del concepto de sentido común en la filosofía de Gilles Deleuze, señalando algunas transformaciones al respecto desde Diferencia y repetición (1968) hasta sus textos de los años ‘80. Mostraremos que el sentido común implica una presencia implícita de la comunidad en el ejercicio de las facultades, que sin embargo invisibiliza y despolitiza su propia presencia, y rastrearemos la letra kantiana para señalar que la comunidad implícita en el sensus communis se revela como una comunidad «mayoritaria» relativa a un modelo que no se corresponde con los devenires efectivos.; The aim of this paper is to underline the political dimension of the concept of common sense in Gilles Deleuze’s philosophy, pointing out its transformations from Difference and Repetition (1968) to his texts from the ‘80s. We will show that common sense implies an implicit presence of the community in the exercise of the faculties, and track its Kantian roots in order to reveal the community implicit in the sensus communis as a «majoritarian» community, relative to a model unlike the real becomings.

Matrix assisted laser desorption ionization-time-of-flight mass spectrometry identification of mycobacterium bovis in bovinae Bacanelli, Gisele; Olarte, Larissa C.; Silva, Márcio R.; Rodrigues, Rudielle A.; Carneiro, Paulo A. M.; Kaneene, John B.; Pasquatti, Taynara N.; Takatani, Haruo; Zumárraga, Martín José; Etges, Rodrigo N.; Araújo, Flábio R.; Verbisck, Newton V. In this study, Matrix Assisted Laser Desorption Ionization-Time-of-Flight (MALDI-TOF) mass spectrometry was used to identify Mycobacterium bovis from cattle and buffalo tissue isolates from the North and South regions of Brazil, grown in solid medium and previously identified by Polymerase Chain Reaction (PCR) based on Region of Difference 4 (RD4), sequencing and spoligotyping. For this purpose, the protein extraction protocol and the mass spectra reference database were optimized for the identification of 80 clinical isolates of mycobacteria. As a result of this optimization, it was possible to identify and differentiate M. bovis from other members of the Mycobacterium tuberculosis complex with 100% specificity, 90.91% sensitivity and 91.25% reliability. MALDI-TOF MS methodology described herein provides successful identification of M. bovis within bovine/bubaline clinical samples, demonstrating its usefulness for bovine tuberculosis diagnosis in the future.

The giant radio array for neutrino detection (GRAND): science and design Álvarez Muñiz, Jaime; Alves Batista, Rafael; Balagopal V, Aswathi; Bolmont, Julien; Bustamante, Mauricio; Carvalho, Washington; Charrier, Didier; Cognard, Ismaël; Decoene, Valentin; Denton, Peter B.; De Jong, Sijbrand; De Vries, Krijn D.; Engel, Ralph; Fang, Ke; Finley, Chad; Gabici, Stefano; Gou, QuanBu; Gu, JunHua; Guépin, Claire; Hu, HongBo; Huang, Yan; Kotera, Kumiko; Le Coz, Sandra; Lenain, Jean-Philippe; Lü, GuoLiang; Martineau Huynh, Olivier; Mostafá, Miguel; Mottez, Fabrice; Murase, Kohta; Niess, Valentin; Oikonomou, Foteini; Pierog, Tanguy; Qian, XiangLi; Qin, Bo; Ran, Duan; Renault-Tinacci, Nicolas; Roth, Markus; Schröder, Frank Gerhard; Schüssler, Fabian; Tueros, Matias Jorge The Giant Radio Array for Neutrino Detection (GRAND) is a planned large-scale observatory of ultra-high-energy (UHE) cosmic particles, with energies exceeding 108 GeV. Its goal is to solve the long-standing mystery of the origin of UHE cosmic rays. To do this, GRAND will detect an unprecedented number of UHE cosmic rays and search for the undiscovered UHE neutrinos and gamma rays associated to them with unmatched sensitivity. GRAND will use large arrays of antennas to detect the radio emission coming from extensive air showers initiated by UHE particles in the atmosphere. Its design is modular: 20 separate, independent sub-arrays, each of 10000 radio antennas deployed over 10000 km2. A staged construction plan will validate key detection techniques while achieving important science goals early. Here we present the science goals, detection strategy, preliminary design, performance goals, and construction plans for GRAND.

Tasas de cambio de uso del suelo y agriculturización en el Partido de Tandil, Argentina; Taxas de variação do uso do solo e intensificação da agricultura no Município de Tandil, Argentina; Exchange rates of land use and agriculturization in the Tandil Country, Argentina Vazquez, Patricia Susana; Zulaica, Maria Laura; Somoza, Ailin El proceso de agriculturización, como caso particular y frecuente de cambio en el uso de la tierra, es uno de los propulsores del Cambio Global y causante de transformaciones ambientales. Los objetivos planteados en este trabajo fueron analizar las tasas de cambio anual en el uso del suelo en el partido de Tandil, entre 1988 y 2015, a fin de caracterizar el proceso de agriculturización en los paisajes que lo componen; determinar los cultivos con mayor incidencia en dicho proceso e identificar los principales servicios ecosistémicos afectados. Metodológicamente se obtuvieron imágenes satelitales, se realizaron clasificaciones supervisadas, se emplearon estadísticas oficiales, estudios antecedentes y relevamientos de campo. Los resultados obtenidos muestran un incremento de la superficie destinada a la agricultura en desmedro de la ganadería con una tasa de cambio anual de 3.28 (especialmente en la Llanura distal) y una alteración en la composición de los principales cultivos. Dicho contexto propicia la provisión de servicios ecosistémicos de abastecimiento y el deterioro de la provisión de servicios de regulación. El análisis de los cambios en el uso del suelo constituye una herramienta útil para tomar dimensión del proceso de agriculturización y los impactos ambientales asociados.; O processo de intensificação agrícola, um caso particular e frequente de variação no uso da terra, é um dos motores da alteração global e causador de transformações ambientais. Os objetivos estabelecidos neste trabalho foram analisar as taxas de variação anual do uso da terra no Tandil, entre 1988 e 2015, a fim de caracterizar o processo de intensificação agrícola nas paisagens que o compõem; determinar os cultivos com maior incidência neste processo e identificar os principais serviços ecossistêmicos afetados. Metodologicamente, foram obtidas imagens de satélite e classificações supervisionadas e foram utilizados estatísticos oficiais, estudos de base e levantamentos de campo. Os resultados obtidos mostram um aumento da superfície destinada à agricultura em detrimento da pecuária com uma taxa de variação anual de 3,28 (especialmente na planície distal) e uma alteração na composição dos principais cultivos. O contexto favorece a prestação de serviços ecossistêmicos de abastecimento e a degradação da prestação de serviços de regulação. A análise das variações no uso da terra é uma ferramenta útil para dimensionar o processo de intensificação agrícola e os impactos ambientais associados.; The agriculturization as particular process of change in the use of land is one of the drivers of the Global Change and consequently it causes environmental transformations. The aims of this work were to analyze the exchange rates annual in the use of land in Tandil department, between 1988 and 2015, in order to characterize the process of agriculturization in the landscapes that compose it; to determine the crops with the highest incidence in this process and to identify the main ecosystem services affected. Methodologically were obtained satellite images and supervised classifications. Also were used official statistics, background studies and field surveys. The results shows an increase in the area intended to agriculture at the expense of livestock with an annual change rate of 3.28 (especially in the distal plain) and an alteration in the composition of the main crops. It is observed how this context favors the supplying services and the deterioration of most of the regulating and cultural services. The analysis of changes in land use is a useful tool to take dimension of the process of agriculturization and its associated impacts.

Multiscale approach to electron transport dynamics Bustamante, Carlos Mauricio; Ramírez, Francisco Fernando; Sanchez, Cristian Gabriel; Scherlis, Damián A. Molecular simulations of transport dynamics in nanostructures usually require the implementation of open quantum boundary conditions. This can be instrumented in different frameworks including Green's functions, absorbing potentials, or the driven Liouville von Neumann equation, among others. In any case, the application of these approaches involves the use of large electrodes that introduce a high computational demand when dealing with first-principles calculations. Here, we propose a hybrid scheme where the electrodes are described at a semiempirical, tight binding level, coupled to a molecule or device represented with density functional theory (DFT). This strategy allows us to use massive electrodes at a negligible computational cost, preserving the accuracy of the DFT method in the modeling of the transport properties, provided that the electronic structure of every lead is properly defined to behave as a conducting fermionic reservoir. We study the nature of the multiscale coupling and validate the methodology through the computation of the tunneling decay constant in polyacetylene and of quantum interference effects in an aromatic ring. The present implementation is applied both in microcanonical and grand-canonical frameworks, in the last case using the Driven Liouville von Neumann equation, discussing the advantages of one or the other. Finally, this multiscale scheme is employed to investigate the role of an electric field applied normally to transport in the conductance of polyacetylene. It is shown that the magnitude and the incidence angle of the applied field have a considerable effect on the electron flow, hence constituting an interesting tool for current control in nanocircuits.

Los colectivos artísticos y una mirada acerca de la crisis de 2001: el caso de Arde! Arte, 2001-2006; Artistic collectives and a look on the crisis of 2001: the case of Arde! Arte, 2001-2006 Feldman, Jonathan Hacia finales de la década del noventa, la Argentina se encontraba en una situación socio-económica crítica, resultado de la aplicación de un programa de gobierno alineado con las propuestas del Consenso de Washington. En 2001, la gravedad de la crisis se tornó desesperante y produjo una serie de protestas y manifestaciones que tuvieron su punto más alto el 19 y 20 de diciembre, durante las jornadas conocidas como el Argentinazo. En conjunto con organizaciones populares como agrupaciones de desocupados y piqueteros, algunos colectivos artísticos acompañaron los reclamos con acciones en la vía pública. Arde! Arte fue uno de ellos. Entre 2001 y 2006, el colectivo operó en las calles de Buenos Aires con intervenciones que conjugaron recursos como la ironía, el humor y la denuncia, y lograron tensar la relación entre arte y política desde perspectivas antes inéditas, al tiempo que –conforme a su carácter desjerarquizado y horizontal– contribuyó a generar una mirada y una memoria acerca de la mayor crisis en la historia del país. Este artículo analizará algunas de sus acciones a la luz de las representaciones de la crisis producidas por Arde! Arte y su interacción con otros colectivos contemporáneos como GAC, Etcétera o TPS.; Towards the ends of the nineties, Argentina was in a critic socio-economic situation, result of the application of a governmental program aligned with the proposals of the Washington Consensus. In 2001, the severity of the crisis became despairing and produced a series of protests demonstrations with its highest point during the events of 19th and 20th of December, know was Argentinazo. Together with popular organizations such as unemployed and piquetero2 associations, some artistic collectives accompanied the protests with actions in public spaces. Arde! Arte was one of them. Between 2001 and 2006, the group operated on the streets of Buenos Aires with interventions that conjugated resources like irony, humor and denunciation, and tensed the relationships between art and politics from unprecedented perspectives while –because of its dehierarchized and horizontal nature– contributing to generate a gaze and memory of the biggest crisis in the country’s history. This article will analyze some of their actions in the light of the representations of the crisis produced by Arde! Arte and its interactions with other contemporary collectives such as GAC, Etcétera and TPS.

Representaciones Sociales de la Psicología del Trabajo en Estudiantes de Licenciatura en Psicología en Argentina; Social Representations of Work Psychology in Psychology Students of Argentine Universities Bucosky Yolde, Matías; Fernández, Omar; Zubieta, Elena Mercedes La investigación analiza las Representaciones Sociales de la Psicología del Trabajo (RSPT) en estudiantes de psicología de universidades argentinas. Se plantea que las RSPT estructuran una injerencia procedimental y de gestión en detrimento de la investigación científica, y que se encuentra limitada y modelada por la adherencia al ámbito clínico. Se realizó un estudio de diferencia de grupos, de diseño no experimental, transversal con una muestra intencional no probabilística de 128 estudiantes de psicología de universidades públicas y privadas, 78,9% mujeres y 21,1% varones, con una edad media de 25 años (DT: 7, Max=59, Min=19).Ambas hipótesis se confirman parcialmente, dado que las evocaciones muestran a la investigación científica por fuera del núcleo central, en el cual se observan los procedimientos y la organización; mientras se denotan diferencias en las estructuras en torno al área de inserción entre los que tienden al ámbito clínico y los que no.; The research analyzes the Social Representations of Work Psychology (SRWP) in students of private and public universities of Argentina considering different differential anchorages related to socio-psychological and socio-demographic variables. Astudy of group differences, non-experimental design, cross-sectional, was carried out based on a non-probabilistic intentional sample of 128 psychology students from public (50%) and private (50%) universities (78.9% women and 21.1% males) with an average age of 25 years (SD: 7 years, Max= 59, Min= 19). The evocations fix its performance in organizations or companies in the HR, in areas of personnel selection and training, or in external offices.The major tasks assigned are related with implementing diagnostic evaluations, personnel selection processes, and interventions to encourage motivation or mediate in conflicts.Respect to role abilities, assertivity, empathy, and attitudes towards leadership, with a great knowledge about his interference in the area.

La moda al día: estructuralismo argentino 1969 Walker Sánchez, Carlos El artículo analiza dos aspectos de la recepción del estructuralismo francés en Argentina. En primer lugar, se recopilan una serie de manifestaciones antiestructuralistas publicadas en los semanarios de información y en los diarios. De este modo, se verifica la alta frecuencia de aparición de expresiones antiestructuralistas, las que en buena medida valoraban negativamente las traducciones de los teóricos franceses y las producciones criollas que se reivindicaban de cuño estructural. La recopilación de este material y el análisis del mismo, se hace bajo el supuesto que las manifestaciones que impugnaban su validez e incluso ridiculizaban las manifestaciones vinculadas al estructuralismo, sirven para conformar una "descripción en negativo" de los sentidos con que circulaba el estructuralismo en la Argentina de fines de los sesenta. En otras palabras, el desdén ante el estructuralismo pone en primer plano distintas versiones de un mismo presente, distintas formas de ser contemporáneos, donde las valoraciones divergentes con que la teoría estructural se difundió permiten a su vez expresar las ambiciones y los poderes que se le adjudicaban en ese entonces al estructuralismo.En segundo lugar, se examinan los efectos de la presencia de Severo Sarduy en Buenos Aires, como vía para comparar versiones específicas sobre el estructuralismo local. La visita a Buenos Aires del escritor cubano, antecedida por la reciente publicación por Editorial Sudamericana de su primer libro de ensayos, Escrito sobre un cuerpo, le dan a Sarduy un marcado protagonismo en la prensa general y en los medios específicos. En este marco, se analiza en detalle el virulento y detallado comentario que hiciera Nicolás Rosa sobre los ensayos de Sarduy en la revista Los Libros. Las particularidades de la lectura de Rosa permiten establecer características de la recepción del estructuralismo francés en el seno de la revista Los Libros. Al mismo tiempo, esto lleva a distinguir las filiaciones y metodologías estructuralistas que separaban a Sarduy de Rosa. En suma, tanto las manifestaciones antiestructurales como la fuerte crítica de Rosa a los ensayos de Sarduy, sirven para configurar las características de una moda estructuralista en 1969.

La circulación del esoterismo en América Latina: El conde de Das y sus viajes por Argentina y Perú, 1892-1900; The circulation of esoterism in Latin America: The conde de Das and his travels through Argentina and Peru, 1892-1900; A circulação do esoterismo na América Latina: O conde de Das e seus viagens pela Argentina e Peru, 1892-1900 Vallejo, Mauro Sebastián; Palma Maturana, Patricia Este artículo examina la trayectoria profesional de Alberto Santini Sgaluppi, o conde de Das, un esoterista que se presentó en Buenos Aires y Lima a fines del siglo XIX, y el impacto de sus espectáculos entre diversos actores sociales en ambas capitales sudamericanas. Argumentamos que individuos como Sgaluppi jugaron un rol esencial en la difusión de conocimientos y fenómenos ligados con el esoterismo y la hipnosis, y que el estudio de sus emprendimientos puede iluminar el desarrollo de los discursos científicos y de los contornos de conocimientos definidos como “ciencia” en la esfera pública y más allá de círculos de expertos.; This paper examines the professional trajectory of Alberto Santini Sgaluppi (“conde de Das”), an esoterist who performed in Buenos Aires and Lima in the late nineteenth century and analyzes the impact of his spectacles on diverse social actors in the two South American capital cities. We argue that individuals like Sgaluppi played a pivotal role in the spread of knowledge about nascent phenomenons linked to esoterism and hypnotism; at the same time, a close examination of his performances throws light on the development of scientific discourses and on the contours of “science” in the public sphere, beyond the conventional circle of experts.; Este artigo examina a trajetória profissional de Alberto Santini Sgaluppi, ou conde de Das, esoterista que se apresentou em Buenos Aires e Lima no final do século XIX, e o impacto de seus espetáculos entre os diversos atores sociais de ambas as capitais sul-americanas. Argumentamos que indivíduos como Sgaluppi desempenharam um papel essencial na disseminação de conhecimento e fenômenos ligados ao esoterismo e à hipnose, e que o estudo de seus esforços pode iluminar o desenvolvimento de discursos científicos e os contornos de conhecimento definidos como “ciência” na esfera pública e para além dos círculos de especialistas.

Feeding strategies alter gene expression of the calpain system and meat quality in the longissimus muscle of Braford steers Coria, Maria Sumampa; Reineri, Pablo Sebastian; Pighín, Darío Gabriel; Barrionuevo, María Guadalupe del Valle; Carranza, Pedro Gabriel; Grigioni, Gabriela Maria; Palma, Gustavo Adolfo Objective: The aim of the present study was to determine the effect of supplementing pasture-finished steers with corn silage on the expression level of the calpain system proteins and beef tenderization. Methods: Thirty Braford steers grazing on summer pasture were used for the study. For 120 days fifteen animals were supplemented with corn silage at 1% of body weight per head per day (Suppl) whereas the remaining 15 steers only received pasture (Contr). Carcass and meat traits were evaluated and compared between groups. Gene expression and activities of proteases (calpain 1 and calpain 2) and inhibitor (calpastatin) were measured using real-time polymerase chain reaction and casein zymography. Results: Carcass and meat traits were significantly different between feeding systems. Supplemented steers showed higher hot carcass weight (p<0.01), fat content (p = 0.02), and Warner-Bratzler shear force (p = 0.03). Furthermore, the control group showed higher protease:inhibitor ratios, at mRNA (p = 0.01) and protein levels (p<0.10). Warner-Bratzler shear force and mRNA calpains:calpastatin ratio were associated in both feeding systems (p<0.01). Conclusion: Based on the results obtained in the study, beef tenderness differences among finishing strategies could be modulated through differential expression of the calpain system proteins.

Preservative effect of algae extracts on lipid composition and rancidity development in brine-canned Atlantic chub mackerel (Scomber colias) Barbosa, Roberta G.; Trigo, Marcos; Campos, Carmen Adriana; Aubourg, Santiago P. This research focuses on the lipid fraction and the rancidity stability of commercial canned Atlantic Chub mackerel (Scomber colias). For it, two different concentrations of aqueous extracts of two abundant algae (Fucus spiralis and Ulva lactuca) are included in the brine-packing (aq. 2% NaCl) medium during mackerel canning. Quality analyses are carried out after a 3-month canned storage (20 °C). Phospholipids, sterols, and α-tocopherol contents show a marked loss as a result of canning, this loss being mostly inhibited when considering the canned fish packed in the presence of the most concentrated algae extracts. Breakdown of free fatty acids and peroxides produced during the thermal treatment is inhibited by the presence of the algae extracts, a higher retention of such molecules being observed by increasing the algae extract concentration. Analysis of fluorescent compounds formation (tertiary lipid oxidation) shows a marked increase after canning, this increase being partly inhibited by the presence of antioxidant compounds present in the algae extracts; interestingly, oxidation inhibition is found more important in canned fish corresponding to F. spiralis batches than U. lactuca. A preservative effect on lipid constituents and rancidity development is concluded by the presence of algae extracts in the packing medium. Practical Applications: The extensive heat treatment involved during fish canning has been reported to produce breakdown of constituents, lipid damage (oxidation and hydrolysis) development showing a marked effect on nutritional and sensory properties; furthermore, this effect has shown to be greater when a brine medium is applied as packing system. Marine algae have been described as being a relevant source of chemical constituents including an antioxidant and antibacterial behavior. In the current work, employment of a commercial brine-packing including aqueous algae extracts shows a preservative effect on the lipid fraction (composition and rancidity stability) during the canning process of Atlantic Chub mackerel. The proposed strategy may open the way to the development of a natural biopreservation for commercial canned fish due to the simple methodology employed and the abundancy of the two algae chosen for the study. Further research should envisage optimization of the preservative compounds extraction by advanced technologies. Aqueous extracts of algae Fucus spiralis and Ulva lactuca are included in the packing medium during Atlantic Chub mackerel (Scomber colias) canning. As a result, an inhibitory effect on lipid composition changes and rancidity development is obtained. Better results are observed by employing alga F. spiralis.

Flour from fruits and vegetables waste with addition of a South-American pepper (Capsicum baccatum) proposed as food ingredient de Sá Mendes, Nathânia; Favre, Leonardo Cristian; Rolandelli, Guido; Dos Santos Ferreira, Cristina Isabel; de A.Gonçalves, Édira C. B.; Buera, Maria del Pilar The objective of this work was to evaluate the physicochemical properties of previously characterised flours obtained by milling the solid waste from the manufacture of an isotonic drink produced with various fruits and vegetables (FVR) to which powdered pepper fruits (PF) were added. Aqueous extracts were also prepared and encapsulated for protecting their functional compounds and improving their solubility. The encapsulation yields of the spray-drying processes were 90% and 64% for PF and FVR-PF, respectively. The addition of PF to FVR improved antioxidant capacity, stability and appearance, providing reddish colour. FT-IR spectra reflected the addition of PF by changes in the absorbances at wave numbers typical of carotenoids, acylglycerols, chlorophylls and those related to antioxidant capacity. The encapsulated extracts could be applied when solubility is needed in hydrophilic media. The obtained flours with PF addition are suitably cheap, stable functional food ingredients for industrial uses, such as breading or seasoning ingredients.

Functional and structural effects of hydrocolloids on Ca(II)-alginate beads containing bioactive compounds extracted from beetroot Aguirre Calvo, Tatiana Rocio; Santagapita, Patricio Roman; Perullini, Ana Mercedes In the present research, valuable bioactives such as betacyanin and polyphenols of beetroot leaf and stem (a food waste)were extracted and encapsulated in Ca(II)-alginate beads, using sucrose, arabic and guar gums, and low and high methoxyl pectins as excipients. A complete SAXS evaluation from the molecular to the supramolecular changes (1?100 nm)produced by excipients and extracts on the microstructure of the hydrogel network was performed. Thus, combining structural-functional information allows for the design of Ca(II)-alginate systems based not only on functional aspects. Here we demonstrate that the presence of hydrocolloids affected the alginate dimers size and density, the rods size and compactness as well as their interconnectivity. Nevertheless, these modifications can be overlied by the presence of an extract, which leads to alginate coordination prior to gelation, strongly affecting the resulting microstructure. Among the used hydrocolloids, only guar gum achieves the two proposed criteria: increasing functional properties and generating stable microstructural modulations.

El humor gráfico, un medio idóneo para promover el aprendizaje del dibujo, la escritura y su articulación. Creaciones de niños y adolescentes Pedrazzini, Ana Mercedes; Bugallo, Lucía; Zinkgraf, Constanza El humor gráfico puede ser entendido como un discurso multimodal en el que diversos signos -en su mayoría icónicos, plásticos y lingüísticos- interactúan para producir sentido y crear un efecto humorístico. La multimodalidad se manifiesta también por otras vías, compartidas con un tipo de discurso muy próximo, la historieta: la gestualidad es dibujada; los ruidos son escritos a través de onomatopeyas que se encuentran integradas visualmente en el relato; el movimiento es representado en la imagen fija a partir de líneas cinéticas; los diálogos entre los personajes -que remiten a la oralidad y son concebidos para ser escuchados más que para ser leídos- son escritos en globos cuya forma cambia según se trate de conversaciones, susurros o gritos.Diversos trabajos analizan la relación modal entre el dibujo y la escritura en el humor gráficoproducido por profesionales, siendo un terreno poco explorado el del humor gráfico de niños yadolescentes. En el presente trabajo buscamos aportar a la comprensión de las diversas formasen que niñas/os y adolescentes articulan los modos verbal y visual en la creación de humorgráfico. En particular, analizaremos: a) diversas estrategias implementadas en la articulaciónvisual-verbal, atendiendo a dificultades encontradas y sorteadas con éxito variable y b) el repertorio de recursos del género desplegados en las viñetas producidas. Basándonos enalgunos trabajos que advierten la dificultad de clasificar varios de los recursos como inequívocamente visuales o lingüísticos, proponemos entenderlos como parte de un continuumo entrecruzamiento modal. El corpus de análisis comprende 154 viñetas humorísticas producidas por niñas/os yadolescentes de 10 a 19 años durante nueve talleres de interpretación y producción de humorgráfico realizados en la ciudad de San Carlos de Bariloche y General Roca (2015-2018). Realizamos un análisis de la articulación verbal-visual a partir de la aplicación de categoríaselaboradas en trabajos previos (complementariedad, contradicción, predominio verbal/visualcon funciones específicas) e identificamos el tipo y cantidad de recursos del género. Cada autora codificó independientemente cada texto y luego se contrastaron las codificaciones. Las discrepancias fueron resueltas mediante discusión. En cuanto a la articulación modal, los resultados indican una primacía de la relación de complementariedad entre ambos modos, lo cual da cuenta del esfuerzo de los participantes por sacar provecho del potencial de cada modo semiótico. En menor medida los textos se articularon con un predominio visual, en los cuales lo verbal redundó parcialmente. Asimismo, identificamos la utilización de uno o dos recursos diferentes por texto, siendo los globos, las líneas cinéticas, las etiquetas y los carteles los más numerosos. Atendiendo a usos con mayor o menor grado de convencionalidad e innovación, describimos diversas estrategias llevadas acabo para producir viñetas inteligibles, por ejemplo la enumeración de globos y/o viñetas. Relevamos también algunas dificultades en la implementación de recursos, varias de las cuales remiten a los globos, tales como la confusión entre tipos de globos y la inadecuada ubicación de personajes y globos, entre otros.

La revista Riel y Fomento y su proyecto de modernidad americanista (1922-1928); A revista Riel y fomento e seu projeto de modernidade americanista (1922-1928); The magazine Riel y fomento and its project for an americanist modernity (1922-1928) Fasce, Pablo Javier El siguiente artículo se centra en Riel y fomento, revista argentina publicada por la Administración General de los Ferrocarriles del Estado entre 1922 y 1935. Con un enfoque explícitamente nacionalista, la publicación abordó asuntos de la actualidad ferroviaria argentina acompañados de artículos vinculados al fomento del turismo y la difusión de las artes y la arquitectura. La investigación estará centrada en el período 1922-1928 y profundizará en varios aspectos, como la participación de artistas e ilustradores, las contribuciones realizadas por gestores e intelectuales y el rol de las imágenes y artículos en la revista.

Com uma abordagem explicitamente nacionalista, a publicação abordou questões de notícias ferrovias argentinas acompanhadas de artigos relacionados à promoção do turismo e a disseminação das artes e arquitetura. A pesquisa será focada no período 1922-1928 e será aprofundada em vários aspectos, como a participação de artistas e ilustradores, as contribuições de gestores e intelectuais e o papel das imagens e artigos na revista. Como hipótese principal, argumento que Riel y fomento articulou em suas páginas um projeto de modernização social e cultural focado no poder “civilizatório” da ferrovia, traduzível no crescimento agrícola e industrial e no desenvolvimento de uma autêntica cultura de valores americanistas.; The following paper focuses on Riel y fomento, an argentinian magazine published by the General Administration of the State Railways between 1922 and 1935. With an explicitly nationalist approach, the publication addressed railways issues accompanied by articles related to the promotion of tourism and the dissemination of arts and architecture. The research will be focused on the period 1922-1928 and will delve into several aspects, such as the participation of artists and illustrators, the contributions made by managers and intellectuals and the role of images and articles in the magazine. As a main hypothesis, I argue that Riel y fomento articulated in its pages a project of social and cultural modernization centered on the “civilizing” power of the railroad, translatable in agricultural and industrial growth and in the development of an authentic culture of Americanist values.

Assembly of spheroid-dominated galaxies in the EAGLE simulation Rosito, María Sol; Tissera, P. B.; Pedrosa, Susana Elizabeth; Rosas Guevara, Y. Context. Despite the insights gained in the last few years, our knowledge about the formation and evolution scenario for the spheroid-dominated galaxies is still incomplete. New and more powerful cosmological simulations have been developed that together withmore precise observations open the possibility of more detailed study of the formation of early-type galaxies (ETGs).Aims. The aim of this work is to analyse the assembly histories of ETGs in a Λ-CDM cosmology, focussing on the archeologicalapproach given by the mass-growth histories.Methods. We inspected a sample of dispersion-dominated galaxies selected from the largest volume simulation of the EAGLE project.This simulation includes a variety of physical processes such as radiative cooling, star formation (SF), metal enrichment, and stellarand active galactic nucleus (AGN) feedback. The selected sample comprised 508 spheroid-dominated galaxies classified according totheir dynamical properties. Their surface brightness profile, the fundamental relations, kinematic properties, and stellar-mass growthhistories are estimated and analysed. The findings are confronted with recent observations.Results. The simulated ETGs are found to globally reproduce the fundamental relations of ellipticals. All of them have an innerdisc component where residual younger stellar populations (SPs) are detected. A correlation between the inner-disc fraction and thebulge-to-total ratio is reported. We find a relation between kinematics and shape that implies that dispersion-dominated galaxies withlow V/σ L (where V is the average rotational velocity and σ L the one dimensional velocity dispersion) tend to have ellipticity smallerthan ∼ 0.5 and are dominated by old stars. On average, less massive galaxies host slightly younger stars. More massive spheroidsshow coeval SPs while for less massive galaxies (stellar masses lower than ∼ 10 10 M ), there is a clear trend to have rejuvenated innerregions, showing an age gap between the inner and the outer regions up to ∼ 2 Gyr, in apparent contradiction with observationalfindings. We find evidences suggesting that both the existence of the disc components with SF activity in the inner region and theaccretion of satellite galaxies in outer regions could contribute to the outside-in formation history in galaxies with low stellar mass.On the other hand, there are non-negligible uncertainties in the determination of the ages of old stars in observed galaxies. Strongersupernova (SN) feedback and/or the action of AGN feedback for galaxies with stellar masses lower than 10 10 M could contribute toprevent the SF in the inner regions.

Under the Empire of Spontaneous Solidarity: State and Political Action in the Theoretical Durkheimian Project (1892-1893) Inda, Graciela This paper aims at identifying and examining all the principles arisen from the issues of the state and politics in Durkheim’s production during the period 1892-1893, signaled by the publication of his famous thesis on the cohesive role of the division of social labor. According to the in-depth analysis carried out in this article, the most important points of Durheim’s politics are four. Firstly, the conception of the state as an organ that translates an automatic social solidarity because it is an entire entity preexisting any political relationships. Secondly, the distinction of despotism as a regime that implies the complete absorption of individuals by the political apparatus. Thirdly, the problem of the growing enlargement of the state interventions in the individuals’ private life sphere. Finally, the incapacity of any political action to transform the society’s morphology.

CRISPR-CAS9 en medicina, la saga continúa Becu, Damasia Hace solo dos años fuimos testigos de la impactante noticia que anunciaba la corrección del gen anómalo de la enfermedad hereditaria miocardiopatía hipertrófica en embriones humanos por medio de la técnica CRISPR/CAS9 1, 2. Esta noticia movilizó la opinión científica y pública porque era el comienzo de la edición de embriones humanos. En ese momento se plantearon dudas éticas y de validación científica.

Characterization of diatomaceous earth modified by organic ligands for enhanced zinc adsorption Sosa, Griselda Leonor; Fernández Morantes, César; Flores, Federico Manuel; Torres Sanchez, Rosa Maria; Zalts, Anita; Ramírez, Silvana Andrea María In order to enhance zinc adsorption, natural diatomaceous earth was modified by a simple batch procedure incorporating ligands with carboxylic and amine functional groups: ethylenediaminetetraacetic acid and 2-N(hydroxyethyl) iminodiacetic acid were used. The supernatants were analysed by square wave anodic stripping voltammetry monitored titrations to quantify ligand incorporation to the diatomaceous earth. The solids were characterized by energy-dispersive X-ray spectroscopy, scanning electron microscopy, X-ray diffraction, electrophoretic mobility, Fourier transform infrared spectroscopy and thermogravimetric analyses. Ligands modified the surface of the natural solid and were unable to enter the interlayer space of the smectite, main component of diatomaceous earth. Langmuir model was the most suitable to describe Zn(II) adsorption on diatomaceous earth whereas Freundlich showed better fit to data of the modified solids. The incorporation of organic ligands increased zinc retention by ca. 50%.
