La corrupción como problema público en la televisión argentina: interacción entre medios y audiencias; Corruption as a social problem in Argentine TV: interaction between media and audiences Zunino, Esteban; Focas, Brenda Marisa La corrupción irrumpió como un problema público en la Argentina durante la década de los noventa, promovido por un conjunto de grupos sociales emergentes que lo instituyeron a partir de estrategias de denuncia. Ya en los años dos mil, el asunto se estabilizó en las agendas mediática y pública, aunque ligada a otros actores, casos y discursos circulantes. El presente trabajo pretende analizar la relación entre la construcción mediática la corrupción y su percepción pública en los cuatro conglomerados urbanos más importantes de Argentina: Área Metropolitana de Buenos Aires (AMBA), Córdoba, Rosario y Mendoza. A partir de un abordaje metodológico que triangula grupos focales desarrollados en las cuatro ciudades y un análisis de contenido sobre las noticias en los noticieros centrales de los canales trece y once de Buenos Aires, diez y ocho de Córdoba, tres y cinco de Rosario y nueve y siete de Mendoza, se pretende analizar cuál es la relevancia mediática y social del problema. Los resultados evidencian una alta importancia del tema en las agendas informativas, sobre todo en las de los medios de Buenos Aires, que presentan una cobertura partisana del problema. En relación con los públicos, el trabajo muestra que, si bien las audiencias expresan cierta distancia y desinterés con estas noticias, se observan procesos de recepción que pululan entre la polarización afectiva y la saturación cognitiva frente al tema.; Corruption emerged as a public problem in Argentina during the 1990, promoted by emerging social groups that instituted it based on reporting strategies. Already in the 2000s, the issue stabilized in the media and public agendas, although linked to other actors, cases, and discourses. This paper aims to analyze the relationship between the media construction of corruption and its public perception in the Argentinian major cities: Buenos Aires, Cordoba, Rosario, and Mendoza. Based on a methodological approach that triangulates focus groups and a content analysis of the central news programs of channels 13 and 11 of Buenos Aires, 10 and 8 of Cordoba, 3 and 5 of Rosario and 9 and 7 of Mendoza, it is intended to analyze the mediatic and social relevance of the problem. Results evidence a high relevance of corruption in the news agendas, especially in those of the Buenos Aires media, which is consistent with some audience’s perceptions. A partisan coverage awakens a polarized and affective reception that affects the processes of victimization. Likewise, the greater visibility of the issue in Buenos Aires raises divergences linked to the geographical variable, both at the level of content and perception. In relation to the public, results show that, although the audiences express a certain distance and disinterest, reception processes are observed that swarm between affective polarization and cognitive saturation.

The circadian clock gates Drosophila adult emergence by controlling the timecourse of metamorphosis Brandon, Mark Thomas; Bustos González, Liliana; Cascallares, Maria Guadalupe; Conejera, Felipe; Ewer, John The daily rhythm of adult emergence of holometabolous insects is one of the first circadian rhythms to be studied. In these insects, the circadian clock imposes a daily pattern of emergence by allowing or stimulating eclosion during certain windows of time and inhibiting emergence during others, a process that has been described as “gating.” Although the circadian rhythm of insect emergence provided many of the key concepts of chronobiology, little progress has been made in understanding the bases of the gating process itself, although the term “gating” suggests that it is separate from the developmental process of metamorphosis. Here, we follow the progression through the final stages of Drosophila adult development with single-animal resolution and show that the circadian clock imposes a daily rhythmicity to the pattern of emergence by controlling when the insect initiates the final steps of metamorphosis itself. Circadian rhythmicity of emergence depends on the coupling between the central clock located in the brain and a peripheral clock located in the prothoracic gland (PG), an endocrine gland whose only known function is the production of the molting hormone, ecdysone. Here, we show that the clock exerts its action by regulating not the levels of ecdysone but that of its actions mediated by the ecdysone receptor. Our findings may also provide insights for understanding the mechanisms by which the daily rhythms of glucocorticoids are produced in mammals, which result from the coupling between the central clock in the suprachiasmatic nucleus and a peripheral clock located in the suprarenal gland.

¿Juramento hipo... qué?: La participación de médicos en el aparato represivo durante la última dictadura cívico militar argentina (1976-1983); Hipocratic Oath ... What? The participation of doctors in the repressive apparatus during the last Argentine civic-military dictatorship (1976-1983) Casartelli, Marina Paola La participación de profesionales de la salud constituyó un elemento central para la concreción y funcionamiento del plan sistemático de exterminio desatado por las Fuerzas Armadas durante la última dictadura cívico militar en Argentina. Desde la atención a las mujeres embarazadas detenidas ilegalmente, la confección de certificados de nacimiento falseados de los bebés nacidos en cautiverio, la participación en sesiones de tortura, entre otros, el accionar de varios médicos demostró su compromiso con los fines del aparato represivo que pretendía aniquilar a un sector de la sociedad calificado como subversivo. En el presente trabajo propongo, a partir de una metodología cualitativa, un análisis de sentencias judiciales con el objetivo de vislumbrar las maneras en que los médicos han servido a los fines del terrorismo de Estado y finalmente condenados en posteriores juicios penales por la comisión de dichos delitos. Este análisis me permitirá indagar en la responsabilidad de los médicos en torno a los crímenes de la dictadura, como también en la manera en que los tribunales han interpretado los mismos. Como se verá a continuación, los delitos en cuestión fueron comprendidos como parte del aparato represivo y, por ello mismo, condenados bajo la figura jurídica de delitos de lesa humanidad.; The participation of health professionals was a central element for the implementation and operation of the systematic plan of extermination unleashed by the Armed Forces during the last civic-military dictatorship in Argentina. From the care of illegally detained pregnant women, the preparation of falsified birth certificates of babies born in captivity, the participation in torture sessions, among others, the actions of several doctors demonstrated their commitment to the aims of the repressive apparatus that was intended annihilate a sector of society, branded as subversive. In the present work I propose, based on a qualitative methodology, an analysis of judicial sentences in order to glimpse the ways in which doctors have served the purposes of State terrorism and finally convicted in subsequent criminal trials for the commission of said crimes. This analysis will allow me to inquire into the responsibility of doctors regarding the crimes of the dictatorship, as well as the way in which the courts have interpreted them. As will be seen below, the crimes in question were understood as part of the repressive apparatus and, for this reason, were condemned under the legal status of crimes against humanity.

Nouvelles pratiques de mobilité active et collective dans la ville de Buenos Aires; Prácticas emergentes de movilidad activa y colectiva en la ciudad de Buenos Aires Di Virgilio, Maria Mercedes; Ramos Mancilla, Oscar Des pratiques de mobilité active naissent dans la ville de Buenos Aires : il s’agit de promenades collectives à pied ou en bicyclette. Ces pratiques font partie de l’ensemble d’alternatives à la mobilité quotidienne, mais leurs caractéristiques spécifiques rendent possibles d’autres sortes d’interactions et d’échanges liés aux environnements urbains. Ce travail propose une approche ethnographique de ces pratiques pour comprendre leur insertion dans le cadre plus vaste des courants et des déplacements et pour identifier la capacité d’action des personnes participant aux promenades dans les transformations de la ville.; En la ciudad de Buenos Aires, están emergiendo prácticas de movilidad activa. Se trata de paseos colectivos que se realizan a pie o en bicicleta. Estas prácticas forman parte del conjunto de alternativas para la movilidad cotidiana pero, por sus características específicas, posibilitan otro tipo de interacciones e intercambios vinculados a los entornos urbanos. En este trabajo, realizamos un acercamiento etnográfico a estas prácticas para comprender las maneras en las que se insertan en el marco más amplio de los flujos y desplazamientos, y para identificar la capacidad de agencia en las transformaciones de la ciudad de las personas que participan en los paseos.

Nuevas reglas sobre la investigación de accidentes de aviación en la Argentina. Su articulación con el Código Aeronáutico y el Anexo 13; new rules on the investigation of aviation accidents in argentina. How they tie in with the aeronautical code and annex 13 Capaldo, Griselda Delia Los bajos índices de siniestralidad registrados en el transporte aéreo se deben a la investigación sistemática de los accidentes sufridos por la aviación civil, tanto doméstica como mundial. Esa investigación técnica está sujeta a un amplio abanico de normas nacionales e internacionales. El propósito de este trabajo es analizar el sistema legal vigente en Argentina, sobre todo a partir de la última ley sobre seguridad en el transporte, y compararla con las normas recomendadas por la Organización de Aviación Civil Internacional. Se incluyen someras referencias a los organismos de un número selecto de países, escogidos al azar entre varios, que tienen a su cargo la tarea de investigar los accidentes aeronáuticos.; The low accident rates in air transport are a consequence of the systematic investigation of accidents registered by civil aviation, at both domestic and global levels. That technical inquiry is governed by a wide range of national and international rules and standards. The purpose of this work is to analyze the current legal system in Argentina, especially from the latest law on transport safety, and to compare it with the standards recommended by the International Civil Aviation Organization. Additionally, brief references to agencies in charge of investigating aircraft accidents in a select number of countries —randomly chosen— are also included.

I dannati della terra: The italian left facing the third world on the eve of 1968 Mestman, Mariano Ernesto The Italian film I dannati della terra (The Damned of the Earth) (Orsini and Filippi 1968) is a prominent example of the connection between the European cinema of intervention and the Third World struggles of the 1960s. Set as a ‘film within a film’, the movie tells the story of a leftist filmmaker, Fausto Morelli, who faces the challenge of finishing a film about the liberation struggles of sub-Saharan Africa by building on the documentary footage that was bequeathed to him by his student and friend, the young Abramo Malonga, an African (Bantu). This article recovers overlooked and little-known documents about the film to show that it is the expression of an active cinematic Third Worldism forged in previous years between the legacy of the Resistenza Partigiana (Italian Resistance) and the Third World struggles of the 1960s. At the same time, the article analyses the ways in which the film ‘dialogues’ with experimental trends of the contemporary avant-garde artistic scene in order to challenge the viewer to debate the ‘open ideological hypothesis’ of the film and take an active part in the political struggles of the time.

Multimodal neurocognitive markers of frontal lobe epilepsy: Insights from ecological text processing Moguilner, Sebastian Gabriel; Birba, Agustina; Fino, Daniel; Isoardi, Roberto Andrés; Huetagoyena, Celeste; Otoya, Raúl; Tirapu, Viviana; Cremaschi, Fabian; Sedeño, Lucas; Ibáñez, Agustín; García, Adolfo Martín The pressing call to detect sensitive cognitive markers of frontal lobe epilepsy (FLE) remains poorly addressed. Standard frameworks prove nosologically unspecific (as they reveal deficits that also emerge across other epilepsy subtypes), possess low ecological validity, and are rarely supported by multimodal neuroimaging assessments. To bridge these gaps, we examined naturalistic action and non-action text comprehension, combined with structural and functional connectivity measures, in 19 FLE patients, 19 healthy controls, and 20 posterior cortex epilepsy (PCE) patients. Our analyses integrated inferential statistics and data-driven machine-learning classifiers. FLE patients were selectively and specifically impaired in action comprehension, irrespective of their neuropsychological profile. These deficits selectively and specifically correlated with (a) reduced integrity of the anterior thalamic radiation, a subcortical structure underlying motoric and action-language processing as well as epileptic seizure spread in this subtype; and (b) hypoconnectivity between the primary motor cortex and the left-parietal/supramarginal regions, two putative substrates of action-language comprehension. Moreover, machine-learning classifiers based on the above neurocognitive measures yielded 75% accuracy rates in discriminating individual FLE patients from both controls and PCE patients. Briefly, action-text assessments, combined with structural and functional connectivity measures, seem to capture ecological cognitive deficits that are specific to FLE, opening new avenues for discriminatory characterizations among epilepsy types.

Geometric morphometrics reveal complex shape variation patterns at different geographic scales in the patagonian gastropod Trophon geversianus Nieto Vilela, Rocío Aimé; Vrdoljak, Juan Esteban; Giulianelli, Sebastian Jesus; Bigatti, Gregorio; Marquez, Federico Environments with strong gradients in physical conditions, such as rocky intertidal, induce animal morphological strategies to face them. The gastropod Trophon geversianus inhabit within the intertidal and subtidal habitats of Patagonian rocky shores. Although there is a wide knowledge of the phenotypic differences of this species regarding habitats (i.e., intertidal/subtidal), little is known about the interaction between habitat and latitude. Here, we studied form variation (size and shape) by using 3D geometric morphometric of T. geversianus shells from alive gastropods and analyzed the phenotypic effect from micro-scale(habitat), macro-scale (latitude), and the interaction habitat-latitude (site). Lastly, we tested the classification accuracy of the shape variable for each predictor variable and a synthetic variable (from a cluster analysis). We found that habitats and sites had the greatest influence on shape variation. Moreover, we found that the largest shell sizes were more likely to be located in subtidal habitats. Also, the size differences between sites were not negligible. Finally, habitat demonstrated the highest classification accuracy for shape, even higher than genetically determined (sex) and synthetic variables. We found that the gastropods from the intertidal habitat presented a globular morph with shorter spire and larger relative size of the shell aperture, while subtidal gastropod showed an elongated morph, with smaller aperture and longer spire. We present evidence of the complexity of size and shape variation in T. geversianus, highlighting that site-dependence on shape variation must be considered in geometric morphometrics studies at a latitudinal scale.

Kartographie der Gegenoffensive: Das Gespenst des Feminismus; Cartography of the Counteroff ensive: The specter of feminism Gago, Maria Veronica Die feministischen Bewegungen weltweit und die sich darin artikulierenden Feminismen fordern die etablierten Mächte heraus, und diese haben eine dreifache – kirchliche, ökonomische und militärische – Gegenoff ensive entfacht, gestützt unter anderem auf die öff entliche Verurteilung der ›Gender-Ideologie‹. Dabei werden verschiedene Taktiken genutzt. So wird die ›Gender-Ideologie‹ mit dem Kolonialismus verknüpft oder der Feminismus als triviale Politik der Mittelklasse infantilisiert und den allgemeinen Nöten großer Teile der Bevölkerung entgegengestellt.; Feminist movements around the world and the feminisms articulated within them are defying the established powers. Th e latter have unleashed a counter-off ensive based, among other things, on the public condemnation of ‘gender ideology’. Various tactics are used to achieve this. For example, ‘gender ideology’ is linked to colonialism, or feminism is infantilised as a trivial middle-class policy and set against the general needs of large parts of the population.

El voto transnacional de los grupos migrantes en Argentina Cruset, Maria Eugenia; Silva, María Paz; Malagamba, María Lara Los nuevos estudios en ciencias sociales han permitido entender los procesos migratorios como fenómenos dinámicos que no se circunscriben a las fronteras de los Estados nación y que dan una proyección de acción en origen y en destino a los grupos migrantes. Esto nos lleva a reformular conceptos tradicionales como el de ciudadanía política. En este trabajo, analizaremos el voto transnacional de los inmigrantes italianos, croatas y paraguayos en la Argentina.; New studies in Social Sciences have allowed us to understand migratory processes as dynamic phenomena that are not circumscribed to the borders of nation-states and that give a projection of action in origin and destination to migrant groups. This leads us to reformulate traditional concepts such as political citizenship. In this paper we will analyze the transnational vote of Italian, Croatian and Paraguayan immigrants in Argentina.

Evaluación de la memoria emocional en niños: metodologías y problemas éticos; Evaluation of emotional memory in children: methodologies and ethical problems Jaume, Luis Carlos; Gago Galvagno, Lucas Gustavo; Elgier, Angel Manuel; Azzollini, Susana Celeste La investigación de la memoria emocional lleva ya algunas décadas de prolíficos estudios publicados, estudiando a adultos y niños.

Información dura-pública y blanda-privada publicada por candidatos y candidatas en Instagram durante la campaña electoral en Argentina 2019; Hard-public information and soft-private information posted by candidates on Instagram during the 2019 Argentinian electoral campaign García Beaudoux, Virginia Inés; Slimovich, Ana En este artículo se presentan los resultados de una investigación que explora las características de las publicaciones efectuadas en Instagram por candidatos y candidatas a cargos electivos en Argentina durante la campaña para las elecciones 2019. Se analizó la proporción de información dura-pública e información blanda-privada o politainment que publicaron, y qué tipo de publicación recibió más likes. Los resultados indican la necesidad de redefinir las categorías analíticas “información dura” e “información blanda” tal como se las utiliza actualmente para estudiar este tipo de fenómenos de comunicación política.; This paper presents the results of a research that explores the main features of Instagram publications of the candidates that participated in the electoral campaign that took place in Argentina in 2019. The proportion of hard-public information and soft-private information or politainment was analyzed, as well as which type of publications received more “likes”. The results indicate the need to redefine the analytical categories hard information and soft information as they are currently used to study political communication phenomena.

Protección social, políticas de cuidados y discapacidad para personas mayores: Argentina 2016-2020; Social protection, care and disability policies for the elderly: Argentina 2016-2020 Venturiello, María Pía; Cirino, Estefanía Claudia; Palermo, María Cecilia El elevado envejecimiento demográfico acompañado de un sostenido crecimiento de la discapacidad son fenómenos que influyen en las transferencias intergeneracionales, en el aumento de la demanda de los servicios de salud y de cuidados de larga duración y en las políticas de previsión social para las personas mayores. Este escenario plantea desafíos sociales y políticos a nivel estatal: ¿se cumplen las leyes de protección integral para las personas con discapacidad? ¿Cómo afectan las reformas previsionales en la situación de los jubilados y pensionados actuales y futuros? ¿Qué rupturas y continuidades se encuentran entre las políticas públicas llevadas a cabo en los últimos dos gobiernos del país? En un contexto de fragmentación de las políticas de protección social, las estrategias del Estado dirigidas hacia personas mayores y hacia personas con discapacidad no conforman un sistema integral y continuo. Esto se refleja en las medidas tomadas en las últimas dos gestiones de gobierno encabezadas por Mauricio Macri (2016-19) y Alberto Fernandez (2019-en curso). En el contexto actual de pandemia por Covid-19, estas cuestiones se han visto agravadas al construirse mecanismos que implican una desprotección sobre los derechos de los ciudadanos de estos grupos. En este trabajo se analizan las transformaciones acaecidas en las políticas de protección social en Argentina referidas a previsión social, salud y cuidados para las personas de 60 años y más y con alguna discapacidad, describiendo las principales medidas implementadas durante estos gobiernos. El interés se centra en describir las normativas teniendo en cuenta continuidades y/o rupturas destinadas a dicha población. La metodología se basa en el relevamiento de fuentes secundarias (leyes y decretos, revisión bibliográfica, análisis de encuestas poblacionales, rastreo de diarios nacionales).; The high demographic aging accompanied by a sustained growth in disability. These are phenomena that influence intergenerational transfers, the increase in demand for health and long-term care services, and social security policies for the elderly. This scenario poses social and political challenges at the state level: are the comprehensive protection laws for people with disabilities being complied with? How do pension reforms affect the situation of current and future retirees and pensioners? What breaks and continuities are found between the public policies carried out in the last two governments of the country? In a context of fragmentation of social protection policies, the State's strategies aimed at the elderly and people with disabilities do not make up a comprehensive and continuous system. This is reflected in the measures taken in the last two government administrations headed by Mauricio Macri (2016- 19) and Alberto Fernandez (2019-ongoing). In the current context of the Covid-19 pandemic, these issues have been aggravated by the construction of mechanisms that imply a lack of protection of the rights of the citizens of these groups. This paper analyse the transformations that have taken place in the social protection policies in Argentina regarding social security, health and care for people aged 60 years and over and with some disability, describing the main measures implemented during these governments. The interest is focused on describing the regulations taking into account continuities and / or ruptures aimed at said population. The methodology is based on the survey of secondary sources (laws and decrees, bibliographic review, analysis of population surveys, tracking of national newspapers.

Pomba gira y otr@s chic@s del montón: Kimbanda queer en Buenos Aires; Pomba gira and other girls of the heap: Kimbanda queer in Buenos Aires Ojeda, Pablo Maximiliano Este artículo analiza las prácticas de un grupo de mujeres trans y hombres gays no binarios, miembros iniciados de un templo afroumbandista del Gran Buenos Aires. En particular, profundiza sobre sus experiencias de expresión sexo-genérica en torno a la kimbanda, línea que experimenta en los últimos años un notable crecimiento en el ámbito local. Mediante observaciones y entrevistas en profundidad, indaga en el vínculo que se establece entre los adeptos y la entidad femenina patrocinante del ritual, Pomba Gira. En este sentido, explora las construcciones identitarias que se cimentan en el transcurrir cotidiano de la vida en el templo legitimadas por aspectos míticos, sociorreligiosos e históricos.; This paper analyzes the practices of a group of trans women and non-binary gay men, initiated members of an Afro-Umbandista temple in Buenos Aires. In particular, delves into her experiences of gender expression around kimbanda, a line that has experienced a remarkable growth in recent years at the local level. Through in-depth observations and interviews, she investigates the link established between the followers and the female sponsor of the ritual, Pomba Gira. Finally, it identifies that this identity construction is not only based on the daily life of the temple, but is legitimized by mythical, socio-religious and historical aspects.

La forma de la expansión urbana en una ciudad media del interior de la pampa bonaerense desde una perspectiva histórica urbano-ambiental (1779-2021); The shape of urban expansion in a middle city in the interior of the pampa bonaerense from an urban-environmental historical perspective (1779-2021) Giusti, Mariana; Goicoechea, María Eugenia El presente artículo tiene por objetivo analizar las formas y tendencias que adoptó la expansión de la matriz edificada de una ciudad intermedia localizada en el interior de la región pampeana bonaerense (Chascomús, Provincia de Buenos Aires, Argentina). El estudio abarca el período 1779-2021 y se centra en la tríada historia, territorio y norma. Con un diseño metodológico que recupera y sistematiza una gran base empírica, se integran en el análisis: el efecto de las relaciones históricas, económicas y sociales; las características territoriales y ambientales; y la influencia de las normativas en las formas que adoptó la expansión urbana. El trabajo, además de ser ilustrativo de un contexto general de crisis del modelo de desarrollo geográfico basado en la primacía urbana y del cuestionamiento al afianzamiento de estructuras macrocefálicas, aporta al conocimiento de las dificultades que se presentan en este tipo de ciudades, recorriendo su conformación físico-espacial, sus limitaciones, amenazas y potencialidades.; The objective of this article is to analyze the forms and trends adopted by the expansion of the built matrix of an intermediate city located in the interior of the Buenos Aires Pampean region (Chascomús, Buenos Aires Province, Argentina). The study covers the period 1779-2021 and focuses on the triad of history, territory and norm. With a methodological design that recovers and systematizes a great empirical base, the following aspects are integrated into the analysis: the effect of historical, economic and social relationships; territorial and environmental characteristics; and the influence of regulations on the forms adopted by urban expansion. The work, in addition to being illustrative of a general context of crisis of the geographic development model based on urban primacy and the questioning of the consolidation of macrocephalic structures, contributes to the knowledge of the difficulties that arise in this type of cities, covering their physical-spatial conformation, its limitations, threats and potentialities.

Development of a honey-based powder ingredient using a mixture design: Botanical origin effect and hydration properties Rivero, Roy Cristian; Archaina, Diego Alberto; Busquet, Cynthia Melisa; Baldi Coronel, Bertha Mabel; Busch, Verónica María The aim of this research was to develop and characterize a high honey content powder with good functional, sensory and hydration properties. A four-responses (hygroscopicity, solubility, cohesiveness and global sensory acceptability) D-optimal mixture design by Design Expert was used. Three factors were selected for the freeze-drying process: honey (60–80%), gum arabic – GA(0–40%) and whey protein concentrate – WPC (0–40%). Three optimal formulations (physicochemical–OPCP–, sensory–OSP– and combined–OCP–) with 72–74% of honey and different GA:WPC ratios were studied. The model prediction was successfully confirmed for the optimal points. Hydration and antioxidant characteristics were evaluated in optimal formulations for honey of three different botanical origins (Eucalyptus, Citrus and Prairie). Water sorption isotherms were sigmoid shape type II for all samples, with a slight difference at high aw for OSP. Flowability (4.5–16.3Ci), hygroscopicity (19.5–24.4 g/100 g), and solubility (87.1–94.6%), were within typical ranges. The botanical origin showed little influence in the physicochemical characteristics but showed differences in the antiradical activity (Prairie honey showed the highest values). These honey powders could be used in a variety of products in the food industry, as food ingredients or directly as a natural sweetener, promoting and diversifying honey consumption.

Oily Bilge Wastes Harbor a Set of Persistent Hydrocarbonoclastic Bacteria Accompanied by a Variable alkB Gene Composition in Marine Vessel Samples from Southwestern Atlantic Port of Mar del Plata, Argentina Corti Monzón, Georgina de la Paz; Nisenbaum, Melina; Peressutti, Silvia Rita Peressutti; Junca, Howard; García Bonilla, Erika; Murialdo, Silvia Elena The present work provides the first knowledge about the diversity and functionality of the microorganisms occurring in oily bilge wastes, from the port of Mar del Plata, Argentina. We used a culture independent approach, based on massive sequencing of the 16S rRNA gene (Illumina), to analyze the microbiome structure from different oily bilge wastes. To gain insight into functional biomarkers for hydrocarbon (HC) degradation in these wastes, the occurrence of alkB genes in the degrading bacteria communities was also investigated trough PCR-DGGE method. The microbial compositions were determined in bilge waste oily phase (BWOP) samples from a deep-sea, a fishing ship, a dredge ship, a small coastal vessel, and an open pool, where bilge wastes from Mar del Plata’s vessels are deposited. A core microbiome with OTUs classified as bacterial types associated with HC biodegradation was found across all samples. Seven highly predominant and stable bacterial types accounted for 82% of the relative composition determined in all the BWOP samples. These results indicate that oily bilge is a strong selector for bacteria having common taxonomical and functional features, independent of the vessel of collection. Alkane degradation marker gene alkB PCR-DGGE fingerprinting showed distinct diversity patterns among the samples. Our analysis showed that there is a well-defined bacterial assemblage able to withstand and thrive in the harsh conditions of the oily bilge wastes. Also, a well-established aliphatic biodegradation potential marker was detected, indicating that it could promptly be used for the generation of new bioremediation technologies.

Revisiting British Investment in Latin America: The River Plate Trust Group, 1879–1963 Lanciotti, Norma Silvana The article analyses the performance and profitability of the firms controlled by the River Plate Trust Group in Argentina and Uruguay from 1879 to 1960 to challenges the notion that British investments in the Southern Cone involved greater default or insolvency risks because of nationalism, expropriations, and over-taxation. Also known as Morris or Morrison group, River Plate Trust became the most important British business group in the region during the First Global Period, as it controlled a number of public utilities, mortgage and financial firms. Our case shows that the decline of British investment in mortgage and financial activities did not mark the end of this business cycle after WWI; rather, it signalled a change in the direction of capital flows. Capital outflows from host economies to Great Britain—via dividends—continued over the interwar period, with only a brief interruption between 1931 and 1934. The business cycle of British firms entered a new phase, characterized by stagnant British investments and increasing capital returns from Argentina and Uruguay to Great Britain. Moreover, British public utility firms continued to invest in the River Plate until the 1940s, because profits from the region supported the distribution of high dividends to shareholders.

Sulfate performance of calcined illitic shales Cordoba, Gisela Paola; Irassar, Edgardo Fabián In the past, calcined pozzolans were largely used in massive concrete, and nowadays, they appear as an excellent alternative to reduce the clinker factor in general use cement. The pozzolanic activity of two calcined illitic shales (CIS) is verified using different standards, indicating the importance of the water requirement for these pozzolans. The sulfate performance of blended cement containing 0, 20, and 40% of CIS was studied with high and low C3A cement using the ASTM C1012 test. Results show that highly reactive CIS is necessary to control the expansion of high C3A-cement at constant w/cm. For low-C3A cement, the highly reactive CIS provides high-sulfate resistant cement with low CIS-replacement, while the water requirement of the other CIS is the main shortcoming to obtain this property. CIS contributes to sulfate resistance due to the CH-consumption and reduction of ions ingress that impedes ettringite and gypsum formation.
