Prediction of topsoil organic carbon using airborne and satellite hyperspectral imagery

The Airborne Hyperspectral Scanner (AHS) and the Hyperion satellite hyperspectral sensors were evaluated for their ability to predict topsoil organic carbon (C) in burned mountain areas of northwestern Spain slightly covered by heather vegetation. Predictive models that estimated total organic C (TOC) and oxidizable organic C (OC) content were calibrated using two datasets: a ground observation dataset with 39 topsoil samples collected in the field (for models built using AHS data), and a dataset with 200 TOC/OC observations predicted by AHS (for models built using Hyperion data). For both datasets, the prediction was performed by stepwise multiple linear regression (SMLR) using reflectances and spectral indices (SI) obtained from the images, and by the widely-used partial least squares regression (PLSR) method. SMLR provided a performance comparable to or even better than PLSR, while using a lower number of channels. SMLR models for the AHS were based on a maximum of eight indices, and showed a coefficient of determination in the leave-one-out cross-validation R2 = 0.60–0.62, while models for the Hyperion sensor showed R2 = 0.49–0.61, using a maximum of 20 indices. Although slightly worse models were obtained for the Hyperion sensor, which was attributed to its lower signal-to-noise ratio (SNR), the prediction of TOC/OC was consistent across both sensors. The relevant wavelengths for TOC/OC predictions were the red region of the spectrum (600–700 nm), and the short wave infrared region between ~2000–2250 nm. The use of SMLR and spectral indices based on reference channels at ~1000 nm was suitable to quantify topsoil C, and provided an alternative to the more complex PLSR method

Hacia la corresponsabilidad familiar: "Construir lo cotidiano. Un programa de educación parental".

Nowadays, family co-responsability which implies a new model of shared fatherhood and motherhood, is on one of the most important topics when we analyse and study families’ dynamics. The aim of these pages is to present the programme Constructing the daily routines. A programme of family education which has been designed by the research group ASOCED to work with mothers and fathers with children in Pre-primary and Primary Education. We consider this is an important period in parents and children lives as it is in this moment when families start the construction of their educational model in cooperation with another relevant socialization institution, that is, the school. The programme model is based on parents and mothers’ implicit conceptions of the education and socialization of their daughters and sons. Taking these preconceptions into account, the programme tries to check family dynamics, to reconstruct the frame of relations, the division of the tasks and the redistribution of responsibilities, so that habits of equality, solidarity and shared responsibility are promoted in mothers and fathers. Therefore, the programme focuses on the transformation of families attitudes, preferences and beliefs dealing with sexual roles and moreover on the different ways of combining the remunerated and domestic work. The main conclusion could be that it would be impossible to desire and aspire to democratic, egalitarian, participative, adaptative and tolerant societies and families when, inside them, models and spaces of experience of the above mentioned values are not generated and promoted.Dentro de la dinámica familiar, uno de los temas de gran actualidad es la corresponsabilidad familiar, un nuevo modelo de paternidad y maternidad compartida.El objetivo de estas páginas es presentar un programa de educación parental con características propias (“Construir lo cotidiano. Un programa de educación parental”) dirigido a madres y padres con hijas e hijos de Educación Infantil y Primaria elaborado por miembros del grupo de investigación ASOCED. El programa tiene como objetivo abordar el proceso de construcción de un modelo educativo en un momento importante, cuando padres y madres comienzan a colaborar con otra institución socializadora relevante como es la escuela. El modelo que se pretende construir toma como punto de partida las concepciones implícitas que los padres y madres tienen acerca de la educación y socialización de sus hijas e hijos. Partiendo de ellas se pretende revisar la dinámica familiar y reconstruir el marco de relaciones, de división de las tareas y de redistribución de responsabilidades, de manera que fomenten en ellos hábitos de igualdad, solidaridad y responsabilidad compartida Nos centramos, por tanto, en la transformación de las actitudes, preferencias y creencias que la familia posee sobre los papeles sexuales y sobre los modos y maneras de combinar el trabajo remunerado y el trabajo familiar.Difícilmente podemos anhelar y aspirar a una sociedad y unas familias democráticas, igualitarias, participativas, adaptativas y tolerantes, si en su seno no se generan modelos y espacios de vivencia de dichos valores que sirvan de ejemplo y estímulo

Las Vallinas (Teverga, Asturias). An Iron Age and roman farmsteas in northern Spain

[ES] Los obstáculos para la prospección a lo largo del paisaje costero del Golfo de Vizcaya, las limitaciones estructurales y materiales de las unidades de asentamiento más pequeñas, y la falta de un control exhaustivo de las alteraciones actuales del terreno, han ocasionado un vacío en el conocimiento sobre la posible presencia de granjas o caseríos en espacios abiertos durante la Edad del Hierro en la región cantábrica. Presentamos por primera vez la existencia de estas granjas, con los hallazgos en Las Vallinas que confirman el uso agrícola del terreno. Al comparar la información de esta alquería con la de castros habitados de la misma época, aportamos una visión más amplia del desarrollo económico de los antiguos Astures desde finales de la Prehistoria hasta el inicio de la ocupación romana. El impacto de la romanización provocó una alteración sin precedentes de las antiguas estructuras sociales y económicas de los Astures en esta zona, dando lugar a una lenta y continua recuperación de la economía rural a partir de finales del siglo I d.C[EN] Obstacles to prospection along the coastal landscape of the Bay of Biscay, structural and material limitations in smaller settlement units, and a lack of comprehensive monitoring of current alterations to the terrain, have all left a dearth of knowledge about the possible presence of open Iron Age farms or hamlets in the Cantabrian region. Presented here for the first time, we demonstrate the existence of these farms with findings verifying agricultural land use at Las Vallinas. In comparing information from this farm with that from inhabited hillforts of the same period, we are also given a wider picture of the economic development of the ancient Astures from the end of prehistory to the beginning of Roman occupation. The impact of Romanization caused an unprecedented upheaval of the old social and economic structures of the Asturs in the area, instigating a slow and steady recovery of a rural economy from the late 1st century AD

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Multiancestry analysis of the HLA locus in Alzheimer’s and Parkinson’s diseases uncovers a shared adaptive immune response mediated by HLA-DRB1*04 subtypes

Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. Protective HLA-DRB1*04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1*04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues
