Published: July 2017

Resumen El desarrollo de proyectos como estrategia de aprendizaje resulta una herramienta muy potente para activar y potenciar el aprendizaje de los alumnos. Tradicionalmente, la evaluación de proyectos mediante ítems numéricos ha sido la técnica más habitual pero la introducción de las competencias transversales en la evaluación del alumno, obliga a actualizar los criterios y formas de evaluación. La presente comunicación presenta la planificación temporal de una asignatura punto de control de Nivel de Dominio III (Master) con un gran número de alumnos que no han trabajo previamente los anteriores dominios. Dentro de la planificación, se encuentra la evaluación para la cual una rúbrica ha sido desarrollada, en la cual los descriptores contienen los ítems que tradicionalmente han sido evaluados y con los que ahora, se evalúa el grado alcanzado por el alumno en cada indicador. Finalmente, se demuestra que la evaluación del grado de adquisición de los resultados de aprendizaje a través de competencias es posible. Se realiza una comparación de notas obtenidas por el sistema tradicional y por competencias, obteniendo resultados muy similares, cuyas diferencias no afectan a la nota final del expediente del alumno.

Published: July 2017

Resumen:De la necesidad de una mayor participación del alumnado universitario en el proceso de enseñanza-aprendizaje ha surgido el concepto de la docencia inversa. Mediante el uso de esta metodología, el alumno trabaja, de manera independiente, los conceptos más teóricos, con la ayuda de material audiovisual principalmente. Posteriormente, en clase, el alumno realiza actividades más prácticas dirigidas por el profesor y así afianza los conceptos aprendidos. El objetivo del presente trabajo es evaluar el impacto de dicha metodología en la enseñanza de la electrónica analógica en la titulación de Grado en Ingeniería Electrónica y Automática. Se ha aplicado la docencia inversa en los cursos 2014-2015, 2015-2016 y 2016-2017 en el grupo de alto rendimiento académico, que cursa la asignatura en inglés. La valoración del alumnado ha sido muy positiva: un 95% del alumnado considera muy adecuada la metodología. Además, los métodos de evaluación mediante el uso de la herramienta SOCRATIVE se han valorado positivamente y el rendimiento académico del grupo ARA ha mejorado con respecto a los demás grupos, lo cual no sucedió en años anteriores cuando no se aplicaba la docencia inversa.Palabras clave: Clase Inversa, Grupo de alto rendimiento académico, Polimedia, SOCRATIVE.
Innovación y competencia pragmática en las pruebas de evaluación de inglés como segunda lengua.
Authors: Martín Beatriz 
Published: July 2017

En el enfoque comunicativo de la enseñanza de segundas lenguas, la pragmática ocupa un lugar primordial. Sin embargo, su tratamiento sigue siendo insuficiente en el ámbito de la evaluación y las pruebas de lengua. Actualmente hay una gran cantidad de pruebas estandarizadas que se comericializan y administran a miles de usuarios para medir su competencia lingüística y comunicativa en inglés como segunda lengua (ISL). En el presente trabajo se analizan 14 de estas pruebas comerciales desarrolladas por las organizaciones de mayor relevancia en EEUU y Reino Unido; se extraen conclusiones acerca de las similitudes y divergencias que entre estas distintas pruebas encontramos y se describen dos de ellas como ejemplo de innovación docente. Se estudia también el tratamiento que de la evaluación de la competencia pragmática ofrece cada una de ellas. Para llevar a cabo la investigación se han tenido en cuenta los siguientes parámetros: propósito de la prueba , partes y secciones, tipo de preguntas, duración, puntuación, evaluación de la competencia pragmática, formato y disponibilidad de versión informatizada o test adaptativo informatizado (TAI).

Background CO2 levels and error analysis from ground-based solar absorption IR measurements in central Mexico
Authors: Baylon Jorge L. , Stremme Wolfgang , Grutter Michel , Hase Frank , Blumenstock Thomas 
Published: July 2017

Abstract. In this investigation we analyze two common optical configurations to retrieve CO2 total column amounts from solar absorption infrared spectra. The noise errors using either a KBr or a CaF2 beam splitter, a main component of a Fourier transform infrared spectrometer (FTIR), are quantified in order to assess the relative precisions of the measurements. The configuration using a CaF2 beam splitter, as deployed by the instruments which contribute to the Total Carbon Column Observing Network (TCCON), shows a slightly better precision. However, we show that the precisions in XCO2 ( =  0.2095  ⋅  Total Column CO2Total Column O2) retrieved from  >  96 % of the spectra measured with a KBr beam splitter fall well below 0.2 %. A bias in XCO2 (KBr − CaF2) of +0.56 ± 0.25 ppm was found when using an independent data set as reference. This value, which corresponds to +0.14 ± 0.064 %, is slightly larger than the mean precisions obtained. A 3-year XCO2 time series from FTIR measurements at the high-altitude site of Altzomoni in central Mexico presents clear annual and diurnal cycles, and a trend of +2.2 ppm yr−1 could be determined.
Palaeoclimate characteristics in interior Siberia of MIS 6–2: first insights from the Batagay permafrost mega-thaw slump in the Yana Highlands

Published: July 2017

Abstract. Syngenetic permafrost deposits formed extensively on and around the arising Beringian subcontinent during the Late Pleistocene sea level lowstands. Syngenetic deposition implies that all material, both mineral and organic, freezes parallel to sedimentation and remains frozen until degradation of the permafrost. Permafrost is therefore a unique archive of Late Pleistocene palaeoclimate. Most studied permafrost outcrops are situated in the coastal lowlands of northeastern Siberia; inland sections are, however, scarcely available. Here, we describe the stratigraphical, cryolithological, and geochronological characteristics of a permafrost sequence near Batagay in the Siberian Yana Highlands, the interior of the Sakha Republic (Yakutia), Russia, with focus on the Late Pleistocene Yedoma ice complex (YIC). The recently formed Batagay mega-thaw slump exposes permafrost deposits to a depth of up to 80 m and gives insight into a climate record close to Verkhoyansk, which has the most severe continental climate in the Northern Hemisphere. Geochronological dating (optically stimulated luminescence, OSL, and 14C ages) and stratigraphic implications delivered a temporal frame from the Middle Pleistocene to the Holocene for our sedimentological interpretations and also revealed interruptions in the deposition. The sequence of lithological units indicates a succession of several distinct climate phases: a Middle Pleistocene ice complex indicates cold stage climate. Then, ice wedge growth stopped due to highly increased sedimentation rates and eventually a rise in temperature. Full interglacial climate conditions existed during accumulation of an organic-rich layer – plant macrofossils reflected open forest vegetation existing under dry conditions during Marine Isotope Stage (MIS) 5e. The Late Pleistocene YIC (MIS 4–MIS 2) suggests severe cold-stage climate conditions. No alas deposits, potentially indicating thermokarst processes, were detected at the site. A detailed comparison of the permafrost deposits exposed in the Batagay thaw slump with well-studied permafrost sequences, both coastal and inland, is made to highlight common features and differences in their formation processes and palaeoclimatic histories. Fluvial and lacustrine influence is temporarily common in the majority of permafrost exposures, but has to be excluded for the Batagay sequence. We interpret the characteristics of permafrost deposits at this location as a result of various climatically induced processes that are partly seasonally controlled. Nival deposition might have been dominant during winter time, whereas proluvial and aeolian deposition could have prevailed during the snowmelt period and the dry summer season.
A multi-diagnostic approach to cloud evaluation
Authors: Williams Keith D. , Bodas-Salcedo Alejandro 
Published: July 2017

Abstract. Most studies evaluating cloud in general circulation models present new diagnostic techniques or observational datasets, or apply a limited set of existing diagnostics to a number of models. In this study, we use a range of diagnostic techniques and observational datasets to provide a thorough evaluation of cloud, such as might be carried out during a model development process. The methodology is illustrated by analysing two configurations of the Met Office Unified Model – the currently operational configuration at the time of undertaking the study (Global Atmosphere 6, GA6), and the configuration which will underpin the United Kingdom's Earth System Model for CMIP6 (Coupled Model Intercomparison Project 6; GA7). By undertaking a more comprehensive analysis which includes compositing techniques, comparing against a set of quite different observational instruments and evaluating the model across a range of timescales, the risks of drawing the wrong conclusions due to compensating model errors are minimized and a more accurate overall picture of model performance can be drawn. Overall the two configurations analysed perform well, especially in terms of cloud amount. GA6 has excessive thin cirrus which is removed in GA7. The primary remaining errors in both configurations are the in-cloud albedos which are too high in most Northern Hemisphere cloud types and sub-tropical stratocumulus, whilst the stratocumulus on the cold-air side of Southern Hemisphere cyclones has in-cloud albedos which are too low.
Russian Egoism Goes to America? A Case for a Connection between Ayn Rand and the Shestidesiatniki
Authors: Weinacht Aaron 
Published: July 2017

Abstract
This article argues that the egoism of nihilists Nikolai Chernyshevskii and Dmitrii Pisarev was a significant influence on the thought of Ayn Rand. Chernyshevskii and Pisarev are usually cast as influences on Russian socialists. Rand was an unapologetic proponent of capitalism. But these differences in economic philosophy should be seen as secondary to the egoism that was primary for all three thinkers. The claim that Chernyshevskii and Pisarev may have influenced Rand is one that provides a new way to think about the historical significance of nihilism.

Novel microbial phospholipases A (PLAs) can be found in actinomycetes which have been poorly explored as producers of this activity. To investigate microbial PLA production, efficient methods are necessary such as high-throughput screening (HTS) assays for direct search of PLAs in microbial cultures and cultivation conditions to promote this activity. About 200 strains isolated with selected media for actinomycetes and mostly belonging toStreptomyces(73%) andMicromonospora(10%) genus were first screened on agar-plates containing the fluorophore rhodamine 6G and egg yolk phosphatidylcholine (PC) to detect strains producing phospholipase activity. Then, a colorimetric HTS assay for general PLA activity detection (cHTS-PLA) using enriched PC (≈60%) as substrate and cresol red as indicator was developed and applied; this cHTS-PLA assay was validated with known PLAs. For the first time, actinomycete strains were cultivated by solid-state fermentation (SSF) using PC as inductor and sugar-cane bagasse as support to produce high PLA activity (from 207 to 2,591 mU/g of support). Phospholipase activity of the enzymatic extracts from SSF was determined using the implemented cHTS-PLA assay and the PC hydrolysis products obtained, were analyzed by TLC showing the presence of lyso-PC. Three actinomycete strains of theStreptomycesgenus that stood out for high accumulation of lyso-PC, were selected and analyzed with the specific substrate 1,2-α-eleostearoyl-sn-glycero-3-phosphocholine (EEPC) in order to confirm the presence of PLA activity in their enzymatic extracts. Overall, the results obtained pave the way toward the HTS of PLA activity in crude microbial enzymatic extracts at a larger scale. The cHTS-PLA assay developed here can be also proposed as a routine assay for PLA activity determination during enzyme purification,directed evolution or mutagenesis approaches. In addition, the production of PLA activity by actinomycetes using SSF allow find and produce novel PLAs with potential applications in biotechnology.
Morphological connectivity correlates with trait impulsivity in healthy adults
Authors: Li Jingguang , Kong Xiang-Zhen 
Published: July 2017

BackgroundImpulsivity is one crucial personality trait associated with various maladaptive behavior and many mental disorders. In the study reported here, we investigated the relationship between impulsivity and morphological connectivity (MC) between human brain regions, a newly proposed measure for brain coordination through the development and learning.MethodTwenty-four participants’ T1-weighted magnetic resonance imaging (MRI) images and their self-reported impulsivity scores, measured by the Barratt impulsiveness scale (BIS), were retrieved from the OpenfMRI project. First, we assessed the MC by quantifying the similarity of probability density function of local morphological features between the anterior cingulate cortex (ACC), one of the most crucial hubs in the neural network modulating cognitive control, and other association cortices in each participant. Then, we correlated the MC to impulsivity scores across participants.ResultsThe BIS total score was found to correlate with the MCs between the ACC and two other brain regions in the right hemisphere: the inferior frontal gyrus (IFG), a well-established structure for inhibition control; the inferior temporal gyrus (ITG), which has been previously shown to be associated with hyperactive/impulsivity symptoms. Furthermore, the ACC-IFG MC was mainly correlated with motor impulsivity, and the ACC-ITG MC was mainly correlated with attentional impulsivity.DiscussionTogether, these findings provide evidence that the ACC, IFG, and ITG in the right hemisphere are involved neural networks modulating impulsivity. Also, the current findings highlight the utility of MC analyses in facilitating our understanding of neural correlates of behavioral and personality traits.
The role of acceptance and values in quality of life in patients with an acquired brain injury: a questionnaire study
Authors: Van Bost Gunther , Van Damme Stefaan , Crombez Geert 
Published: July 2017

ObjectiveAn acquired brain injury (ABI) is a challenge for an individual’s quality of life (QOL). In several chronic illnesses acceptance has been found to be associated with a better health-related quality of life. This study investigated whether this relationship is also found in patients with ABI. We also explored the impact of the perceived ability to live according to one’s own values (life-values-match).MethodsA total of 68 individuals (18–65 years of age) with an acquired brain injury completed a battery of questionnaires. The relations between health-related QOL (SF-36) and disease specific QOL (EBIQ; European Brain Injury Questionnaire), and personal values (Schwartz Values Inventory) and acceptance (ICQ; Illness Cognitions Questionnaire) were investigated. An additional question measured the life-values-match. Rehabilitation professionals reported the extent of impairment involved.ResultsAcceptance was positively associated with mental aspects of health-related QOL and the EBIQ Core Scale, after demographic variables and the extent of impairment were introduced in the regression. In a post hoc analysis we found that the life-values-match mediated the relationship between acceptance and mental aspects of QOL.ConclusionIn patients with an ABI, promoting acceptance may be useful to protect QOL. Strengthening the life-values-match may be a way to accomplish this.
Geothermal heat flux in the Amundsen Sea sector of West Antarctica: New insights from temperature measurements, depth to the bottom of the magnetic source estimation, and thermal modeling
Authors: Dziadek R. , Gohl K. , Diehl A. , Kaul N. 
Published: July 2017

AbstractFocused research on the Pine Island and Thwaites glaciers, which drain the West Antarctic Ice Shelf (WAIS) into the Amundsen Sea Embayment (ASE), revealed strong signs of instability in recent decades that result from variety of reasons, such as inflow of warmer ocean currents and reverse bedrock topography, and has been established as the Marine Ice Sheet Instability hypothesis. Geothermal heat flux (GHF) is a poorly constrained parameter in Antarctica and suspected to affect basal conditions of ice sheets, i.e., basal melting and subglacial hydrology. Thermomechanical models demonstrate the influential boundary condition of geothermal heat flux for (paleo) ice sheet stability. Due to a complex tectonic and magmatic history of West Antarctica, the region is suspected to exhibit strong heterogeneous geothermal heat flux variations. We present an approach to investigate ranges of realistic heat fluxes in the ASE by different methods, discuss direct observations, and 3‐D numerical models that incorporate boundary conditions derived from various geophysical studies, including our new Depth to the Bottom of the Magnetic Source (DBMS) estimates. Our in situ temperature measurements at 26 sites in the ASE more than triples the number of direct GHF observations in West Antarctica. We demonstrate by our numerical 3‐D models that GHF spatially varies from 68 up to 110 mW m−2.
