Repensando el pasado reciente

Cuando hablamos de políticas de la diferencia nos referimos a la implementación de mecanismos de econocimiento y tolerancia de la diversidad, cada vez más frecuentes al interior de los Estados del ámbito andino. Estos mecanismos de reconocimiento y tolerancia de la diversidad pueden esconder sutiles ecanismos de dominación bajo un discurso y unas prácticas incorporadoras y asimiladoras de lo diverso en el aparato estatal y en los circuitos de acumulación del capital.2 Se trata de unas políticas que pueden ser encontradas no sólo en declaraciones generales y retóricas, sino en explícitas acciones de múltiple vía y ue buscan incorporar el respeto y la tolerancia hacia el otro/otra. La lista sería extensa, pero sólo a manera de ejemplo, y en referencia al ámbito legal, menciono el artículo 171 de la Constitución

Bone accumulation by leopards in the Late Pleistocene in the Moncayo Massif (Zaragoza, NE Spain)

Eating habits of Panthera pardus are well known. When there are caves in its territory, prey accumulates inside them. This helps to prevent its kill from being stolen by other predators like hyenas. Although the leopard is an accumulator of bones in caves, few studies have been conducted on existing lairs. There are, however, examples of fossil vertebrate sites whose main collecting agent is the leopard. During the Late Pleistocene, the leopard was a common carnivore in European faunal associations. Here we present a new locality of Quaternary mammals with a scarce human presence, the cave of Los Rincones (province of Zaragoza, Spain); we show the leopard to be the main accumulator of the bones in the cave, while there are no interactions between humans and leopards. For this purpose, a taphonomic analysis is performed on different bone-layers of the cave

The mineralocorticoid receptor plays a transient role in mouse skin development

3 páginas, 2 figuras. Contiene material suplemenarioGlucocorticoid (GC) hormones can bind two structurally and functionally related steroid receptors: the GC Receptor (GR or Nr3c1) and the mineralocorticoid receptor (MR or Nr3c2), which recognize the same DNA response elements and act as ligand-dependent transcription factors. While the crucial role of GR for skin homeostasis has been widely characterized, the exact role of MR in this tissue deserves further study. We assessed NR3C2 expression in developing and adult WT mouse skin and found a transient peak at embryonic day (E)16.5, which along with low levels of HSD11B2, the enzyme inactivating GCs, supports a role for GC-MR complexes in epidermal maturation. Consistent with this observation, MR-/- embryonic skin showed alterations in early epidermal differentiation that resolved postnatally. The lack of a more severe skin phenotype of MR-/- mice suggests functional compensation by GR in this tissue in the perinatal period.This work was supported by JSPS KAKENHI grant numbers 25870545 and 15K09772.

Association between olfactory dysfunction and mood disturbances with objective and subjective cognitive deficits in long-COVID

Background and purposeThe coronavirus disease 2019 (COVID-19) has been associated with olfactory dysfunction. The persistent symptoms of anosmia or hyposmia were associated in previous studies with the development of memory impairment and mood disturbances. We aimed to investigate the association between the chronicity of reported olfactory dysfunction and subjective and objective cognitive performance in long-COVID patients and to explore whether their emotional symptoms are related to their cognition.MethodsOne hundred twenty-eight long-COVID participants were recruited. Reported symptomatology, subjective memory complaints, anxiety and depression symptomatology, and trait-anxiety were assessed. Subjective memory complaints and mood disturbances were compared among groups of participants with olfactory dysfunction as an acute (AOD), persistent (POD), or nonexistent (NOD) symptom. Seventy-six of the volunteers also participated in a face-to-face session to assess their objective performance on tests of general cognitive function and verbal declarative memory. Objective cognitive performance and mood disturbances were compared among the AOD, POD, and NOD groups.ResultsThe subjective memory complaints and the anxiety and depression symptoms were similar among the groups, but the score in general cognitive function was lower in the participants with symptoms of acute olfactory dysfunction than in those with no olfactory symptoms at any time. Participants’ memory complaints were positively related to their emotional symptoms. The relationship between depressive symptomatology and memory complaints interacted with the olfactory dysfunction, as it only occurred in the participants without symptoms of olfactory dysfunction. Depressive symptomatology and acute olfactory symptoms were negatively associated with general cognitive function and delayed memory performance. The months elapsed from diagnosis to assessment also predicted delayed memory performance. Anxious symptomatology was negatively associated with the immediate ability to recall verbal information in participants who did not present olfactory dysfunction in the acute phase of the infection.ConclusionOlfactory dysfunction in the acute phase of the infection by COVID-19 is related to cognitive deficits in objective tests, and mood disturbances are associated with self-reported and objective memory. These findings may contribute to further understanding the neuropsychological and emotional aspects of long-COVID

Estimating albacore movement rates between the North Atlantic and the Mediterraneal from conventional tagging data

A tag attrition model is fit to albacore tag-recapture data in order to estimate albacore movement rates between the Atlantic and the Mediterranean. The estimated transfer rate from the Atlantic to the Mediterranean is not significantly different from zero, and the estimated annual transfer rate in the opposite direction, under the assumptions of the same catchability and reporting rates is 5,49%. Sensitivity tests to assumed reporting rates and relative catchabilities are performed, and observed lower recovery rates in the Mediterranean may suggest either a lower catchability or reporting rate in this area, that would give an even lower estimate of the transfer rate, which is also supported by information from later tag recaptures of fish tagged in the Mediterranean. The small impact of these transfer rates on stock assessment is discussed and a preliminary assessment of the amount of tagged fish needed in order to get accurate and precise estimates of these low transfer rates is also done by simulating different tagging scenarios.Un modèle de déperdition des marques est ajusté aux données de marquage-recapture du germon afin d’estimer les taux de déplacement du germon entre l’Atlantique et la Méditerranée. Le taux de transfert estimé de l’Atlantique à la Méditerranée n’est pas sensiblement différent de zéro, et le taux de transfert annuel estimé dans la direction opposée, en prenant comme postulat une capturabilité et des taux de soumission de données identiques, s’élève à 5,49%. On a réalisé des tests de sensibilité aux taux de soumission de données supposés et à la capturabilité relative. Les taux de récupération inférieurs observés en Méditerranée suggèrent éventuellement une capturabilité ou un taux de soumission de données plus faible dans cette zone, ce qui donnerait une estimation encore plus faible du taux de transfert. Cela est également appuyé par des informations provenant de récupérations tardives de marques de poissons marqués en Méditerranée. Le faible impact de ces taux de transfert sur l’évaluation du stock est discuté et une évaluation préliminaire du volume de poissons marqués nécessaire pour obtenir des estimations exactes et précises de ces faibles taux de transfert est également réalisée en simulant différents scénarios de marquage.Se ajusta un modelo de tasa de pérdida de marcas a los datos de marcado-recuperación de atún blanco con el fin de estimar las tasas de movimiento del atún blanco entre el Atlántico y el Mediterráneo. La tasa de transferencia estimada del Atlántico al Mediterráneo no se diferencia significativamente de cero, y la tasa de transferencia anual estimada en la dirección opuesta, bajo el supuesto de la misma tasa de capturabilidad y comunicación, es de 5,49%. Se realizaron pruebas de sensibilidad de las tasas de comunicación y capturabilidades relativas supuestas, y las tasas de recuperación inferiores observadas en el Mediterráneo pueden sugerir una tasa de capturabilidad o de comunicación más baja en esta zona, lo que proporcionaría una estimación aún más baja de transferencia, que se ve sustentada por la información de recuperaciones de marcas posteriores de peces marcados en el Mediterráneo. Se discute el bajo impacto de estas tasas de transferencia en la evaluación del stock y también se realiza una evaluación preliminar de la cantidad de peces marcados necesarios para obtener estimaciones precisas y exactas de estas bajas tasas de trasferencia mediante una simulación de diferentes escenarios de marcado

First report of neocosmospora falciformis Causing Wilt and Root Rot of Muskmelon in Spain

‘Cantaloupe’ and ‘Piel de Sapo’ are melon (Cucumis melo L.) varieties cultivated in Spain. In 2018, during a pathogens survey in experimental fields of Valencia and Alicante provinces (southeast Spain), wilt and root rot of melon plants were detected in grafted and ungrafted plants. Disease incidence ranged from 10% (Alicante) to 45% (Valencia). Symptoms included yellowing and wilting of leaves, rotting at the stem base and upper root, and collapse of the entire plant. Samplings were conducted from severely decayed and dead plants. Fragments (0.5 to 1 cm) from rotted lower stems and roots were surface disinfected for 1 min in 1.5% NaOCl, washed twice with sterilized distilled water, and plated onto potato dextrose agar (PDA) with streptomycin sulfate (0.5 g/liter). Plates were incubated at 25°C in the dark for 3 to 5 days. Mycelia resembling Fusarium were isolated and characterized by morphological and molecular methods. Based on their adpressed beige mycelia, growth in concentric rings, and absence of sporodochia, colonies growing on PDA and Spezieller Nährstoffarmer agar were preliminary identified as belonging to the Fusarium solani species complex. On PDA, colonies were white-greyish to pale-cream growing in concentric rings with beige reverse after 6 days. No sporodochia were observed. Macroconidia were slender, falcate, hyaline, ..

Outstanding aspects on the use of spent FCC catalyst in binders

4 pages, 3 fiures, 7 tables.-- En: 1st Spanish National Conference on Advances in Materials Recycling and Eco – Energy Madrid, 12-13 November 2009.-- Editors: F. A. López, F. Puertas, F. J. Alguacil and A. Guerrero.FCC is a waste material from petrochemical plants which has interesting properties for preparing binders. FCC is lightly grey in color, and white FCC-portland cements with L*≥85 can be prepared. FCC reactivity is enhanced by grinding and it is attributed to pozzolanic reaction towards lime. Stratlingite is the main hydrated product from pozzolanic reaction, and CSH and CAH are also formed. Reactivity of FCC is high, and low curing temperature does not affect this contribution to strength in hardened mixtures. Additionally, high strength concrete can be easily prepared, and compressive strength greater 100MPa can be reached. Mixtures with low w/b ratio showed good behaviour in carbonation tests.Authors thank to Ministerio de Ciencia y Tecnología of Spain and FEDER the financial support of MAT 2001-2694 and BIA 2004-0052 projects.Peer reviewe

Los Batanes (Biescas, Spain), a roost site for horseshoe bats in the Pyrenees during the late Pleistocene

Los Batanes C4 is a cave-site in the Spanish Pyrenees, the minimum sediment calendar age was determined to be 15, 234 ± 223 cal BP by radiocarbon dating. The cave opens on the northern bank of an eastern tributary of the River Gállego, at an altitude of 1025 m. The small vertebrates recorded are mainly bats, in order of abundance Rhinolophus euryale, R. ferrumequinum, Myotis sp. and Miniopterus schreibersii. The association suggests that at the time of the accumulation the climate was reasonably similar to the current climate; we situate it within a period of local retreat of the ice-cover in the Gállego Valley during the Lateglacial. This is the highest record of these species of Rhinolophus in the Iberian Quaternary, showing that the R. euryale altitudinal range was similar to its extant range during the favourable periods of the Lateglacial. This could indicate that this taxon was relatively quick in spreading into higher regions whenever climate conditions allowed it

Interculturalidad: problemáticas y perspectivas diversas

Este libro es una muestra de la ampliación de los horizontes reflexivos en torno a la interculturalidad. Se puede, se debe, hoy pensar la filosofía, la política pública, la universidad, la formación del profesorado, las luchas sociales, etc, en clave intercultural. No por un mero afán academicista sino como base para desde ahí construir sociedades interculturales. Hoy ya es lugar común saber que lo intercultural nació vinculado a la simple idea de diversidad; sin embargo, más que nunca es necesario pensarla como posibilidad de ruta crítica de mucho del accionar humano. Este trabajo se publica en el contexto post paro nacional de octubre de 2019. Ahí quedó claro que la interculturalidad tiene que ver con históricas cargas racistas-coloniales y con contemporáneas desigualdades económicas que cruzan geopolíticas globales, regionales y nacionales. Esto nos muestra la necesidad de tomarnos en serio una interculturalidad que apunte a la abolición de las asimetrías sociales en conexión con la apuesta por la construcción de una verdadera plurinacionalidad. Una que exija el respeto a la diferencia en términos políticos y equidad en términos económicos
