OTRA FORMA DE VISITAR EL MUSEO. Una oportunidad para resignificar la Educación Artística desde la acción colectiva en la formación de maestras y maestros
Authors: Vaquero Cañestro Carmen , Texeira Jiménez Rocío 
Published: February 2021

Este estudio plantea la necesidad de implementar otras estrategias de encuentro con el arte contemporáneo en el espacio del museo para la resignificación de la Educación Artística en la formación de maestros y maestras. Para ello, parte del potencial de desarrollar propuestas participativas y artísticas en el centro de arte como medio para redimensionar la experiencia y como posibilidad para modificar los esquemas del alumnado de los Grados de Educación Infantil y Primaria de la Universidad de Málaga en relación al arte contemporáneo, a la visita a un museo y también respecto a la vivencia del espacio educativo desde la interacción grupal. De este modo, se facilita el tránsito de una concepción individualista y estrictamente pasiva, a una construcción activa, colectiva y fundamentada en experiencias performativas. La metodología de investigación artístico-narrativa permite el acceso al relato coral de la experiencia y el análisis de la misma evidenciando su impacto en el alumnado y en las docentes implicadas. Los resultados constatan la idoneidad de propuestas que optan por generar otras dinámicas capaces de dotar de autonomía al alumnado frente a la obra, capaces de propiciar otro tipo de vivencia del espacio educativo y museístico y capaces, también, de posibilitar el encuentro colectivo desde un posicionamiento estético, crítico y activo.Esta investigación está vinculada al Proyecto de Investigación Un aula propia conectada. El portafolio docente como recurso narrativo-artístico de investigación y aprendizaje en la formación de maestros y maestras de Educación Primaria (2019-2020) del I Plan Propio de Investigación y Transferencia de la Universidad de Málaga.
Dejar de mirar hacia fuera para repensarnos hacia dentro: Desacelerar a través del autorretrato
Authors: PEÑA ZABALA MIRIAM 
Published: February 2021

En la primavera de 2020, vivimos en un momento de deceleración forzada, un intervalo espacial que forzosamente interviene en el modo de afrontar la vida y por ende en los procesos educativos. Paradójicamente el sistema capitalista de producción en el que vivimos inmersos ansía volver a lo pasado, a la velocidad sin recoveco, sin observación y sin la pausa necesaria para activar la sensibilidad estética del sujeto que reivindicamos con este texto. Contextualizado en la formación inicial de profesorado, en este texto hacemos uso de la Investigación Basada en Artes y de la creación del autorretrato como una estrategia que permite desacelerar y repensarnos como sujetos únicos capaces de reflexionar críticamente a partir de la construcción de una imagen única. Los resultados obtenidos a partir de esta experiencia, evidencian que la creación artística propicia procesos de aprendizaje encarnados que posibilitan conectar con el mundo a partir de repensarnos hacia adentro posibilitando así convertirnos en sujetos críticos.
Educar en la vulnerabilidad: La educación estética como medio para la transformación social y cultural
Authors: FERRADA SULLIVAN JORGE ALBERTO 
Published: February 2021

El artículo desarrolla un conjunto de argumentos reflexivos, que permiten comprender la relevancia de la educación estética como forma de generar espacios de sensibilidad en la formación escolar chilena, particularmente en territorios ausentes de oportunidades efectivas. Se explican desde diferentes ángulos, la relevenacia que posee la educación estética para la transformación social y cultural en territorios de vulnerabilidad. En su acción formativa, la educación estética comporta un conjunto de nuevas racionalidades vinculadas directamente con las emociones y afecciones que los estudiantes en formación pueden desarrollar. Estos entretejidos del sentir y del pensamiento, permiten ampliar las posibilidades de la creatividad y de la comprensión del mundo que les toca vivir, encontrando soluciones a los problemas que los afectan, sobre todo en los territorios con desigualdades sociales (rurales e insulares) y con muy bajo acceso a una educación de calidad.
Pluraliser — le legs de Heidegger
Authors: Plante Maxime 
Published: February 2021

La publication récente de Geschlecht III permet pour la première fois d’embrasser de manière synoptique le projet Geschlecht et d’en apprécier la cohérence d’ensemble. Je prends le parti de lire la série Geschlecht comme la scène d’un héritage où Derrida se débat littéralement avec le legs heideggérien. J’isole en particulier le ressort de la critique du rassemblement (Versammlung) qui organise la lecture de Derrida dans toute la série. Je propose de distinguer deux niveaux à cette lecture : l’un, où est mis en scène le refus d’un héritage jugé métaphysique ou suspect ; l’autre, que l’on méconnaît plus volontiers, qui pour sa part met en scène un héritage partagé (don, promesse, économie). On verra la valeur de rassemblement apparaître tour à tour de l’un et de l’autre côté de ces lignes de partage, et pluraliser le legs devenir l’enjeu de la scène.
Jacques Derrida : politique et poétique de l’hospitalité
Authors: Michaud Ginette 
Published: February 2021

La question de l’étranger est, on le sait, plus que jamais aujourd’hui d’une brûlante actualité, alors qu’« on laisse s’accomplir l’intolérable : non seulement la mort, la souffrance, la déportation, le malheur sans nom, mais aussi la destruction imbécile des chances de l’Europe et de la Méditerranée dans le monde à venir », comme le voyait déjà Jacques Derrida dans ce constat qu’il formulait en août 1995. Cet article propose une traversée des séminaires et des interventions du philosophe qui en appelle à un autre concept de l’hospitalité en l’arrachant aux fantasmes de l’autochtonie, du sang et même de la langue dite commune. Cette pensée de l’hostipitalité engage une autre expérience de la citoyenneté et du politique, de la responsabilité devant l’autre. Le rapport au non-savoir de l’hospitalité inconditionnelle éclaire aussi pourquoi une politique qui tente de s’y mesurer doit nécessairement engager une invention poétique. Plus que tous les aspects qui se trouvent affectés par la question de l’hospitalité (géopolitique, planification urbaine, travail social, droit international), cette dimension poétique de l’acte d’hospitalité se révèle peut-être ici la plus cruciale.

A concise but informative overview of AI ethics and policy.
Artificial intelligence, or AI for short, has generated a staggering amount of hype in the past several years. Is it the game-changer it's been cracked up to be? If so, how is it changing the game? How is it likely to affect us as customers, tenants, aspiring homeowners, students, educators, patients, clients, prison inmates, members of ethnic and sexual minorities, and voters in liberal democracies? Authored by experts in fields ranging from computer science and law to philosophy and cognitive science, this book offers a concise overview of moral, political, legal and economic implications of AI. It covers the basics of AI's latest permutation, machine learning, and considers issues such as transparency, bias, liability, privacy, and regulation.
Both business and government have integrated algorithmic decision support systems into their daily operations, and the book explores the implications for our lives as citizens. For example, do we take it on faith that a machine knows best in approving a patient's health insurance claim or a defendant's request for bail? What is the potential for manipulation by targeted political ads? How can the processes behind these technically sophisticated tools ever be transparent? The book discusses such issues as statistical definitions of fairness, legal and moral responsibility, the role of humans in machine learning decision systems, “nudging” algorithms and anonymized data, the effect of automation on the workplace, and AI as both regulatory tool and target.

BackgroundThe number of children with obesity has increased in Saudi Arabia, which is a significant public health concern. Early diagnosis of childhood obesity and screening of the prevalence is needed using a simple in situ method. This study aims to generate statistical equations to predict body fat percentage (BF%) for Saudi children by employing machine learning technology and to establish gender and age-specific body fat reference range.MethodsData was combined from two cross-sectional studies conducted in Saudi Arabia for 1,292 boys and girls aged 8–12 years. Body fat was measured in both studies using bio-electrical impedance analysis devices. Height and weight were measured and body mass index was calculated and classified according to CDC 2,000 charts. A total of 603 girls and 374 boys were randomly selected for the learning phase, and 153 girls and 93 boys were employed in the validation set. Analyses of different machine learning methods showed that an accurate, sensitive model could be created. Two regression models were trained and fitted with the construction samples and validated. Gradient boosting algorithm was employed to achieve a better estimation and produce the equations, then the root means squared error (RMSE) equation was performed to decrease the error. Body fat reference ranges were derived for children aged 8–12 years.ResultsFor the gradient boosting models, the predicted fat percentage values were more aligned with the true value than those in regression models. Gradient boosting achieved better performance than the regression equation as it combined multiple simple models into a single composite model to take advantage of that weak classifier. The developed predictive model archived RMSE of 3.12 for girls and 2.48 boys. BF% and Fat mass index charts were presented in which cut-offs for 5th, 75th and 95th centiles are used to define ‘under-fat’, ‘normal’, ‘overfat’ and ‘subject with obesity’.ConclusionMachine learning models could represent a significant advancement for investigators studying adiposity-related issues in children. These models and newly developed centile charts could be useful tools for the estimation and classification of BF%.
Functional analysis of CgWRKY57 from Cymbidium goeringii in ABA response

Published: February 2021

Background
The orchid is one of the top ten Chinese flowers and has high ornamental value and elegant color. However, orchids are vulnerable to abiotic stresses during their growth and development, and the molecular mechanism of the abiotic stress response in orchids is unclear. WRKY proteins belong to a transcription factor family that plays important roles in biotic stress, abiotic stress, growth and development in plants, but little is known about the WRKY family in Cymbidium goeringii.

Methods
The specific fragment of the CgWRKY57 gene of C. goeringii was analyzed by bioinformatics. The expression of the CgWRKY57 gene of C. goeringii under 4 °C, 42 °C water and ABA stress as well as different tissues was detected by real-time fluorescence quantitative PCR. CgWRKY57 gene was overexpressed in wild type Arabidopsis thaliana by inflorescence infection method, and the function of transgenic lines under ABA stress was analyzed.

Results
CgWRKY57 was cloned from C. goeringii and found to encode 303 amino acids. The CgWRKY57 protein is an acidic, nonsecreted hydrophilic protein without a signal peptide or transmembrane domain. The CgWRKY57 protein is located to the nucleus and may function intracellularly according to its predicted subcellular localization. A domain analysis and homology comparison showed that the CgWRKY57 protein has a “WRKYGQK” domain and belongs to Group III of the WRKY family, and a phylogenetic analysis demonstrated that CgWRKY57 is closely related to OsWRKY47. CgWRKY57 was expressed in the roots, stems, leaves and floral organs of C. goeringii, and its expression level was highest in the roots according to real-time qPCR analysis. There were significant differences in CgWRKY57 expression under 4 °C, 42 °C ABA and water stress treatments, and its expression changed greatly under ABA stress. The expression of CgWRKY57 in transgenic plants was significantly higher than that in wild type plants under ABA stress, and the root length and germination rate were reduced in transgenic plants compared to wild type plants.

Conclusions
These results indicate that CgWRKY57 overexpression is responsive to ABA stress, and they provide a foundation for future analyses of the biological functions of the WRKY family in C. goeringii.
Commissioning of a Versa HDTM linear accelerator for three commercial treatment planning systems
Authors: Laub Wolfram U. , Merz Brandon , Kishore Monica 
Published: February 2021

AbstractIn a mixed‐vendor radiation oncology environment, it is advantageous if the department's treatment planning system (TPS) supports the linear accelerators of different vendors. In this publication beam data collection and modeling for the Versa HD linear accelerator in Monaco, Pinnacle, and Eclipse are discussed. In each TPS static field, Intensity‐Modulated Radiation Therapy (IMRT) step and shoot, and Volumetric‐Modulated Arc Therapy (VMAT) plans for flattened and flattening‐filter free photon beams of all available energies were evaluated for field sizes >3 × 3. To compare passing rates, identical beam model validation plans were calculated in each TPS. Eclipse, Monaco, and Pinnacle beam models passed validation measurements in homogeneous materials for a variety of treatment fields, including static, IMRT, and VMAT. In the case of Eclipse, the “dosimetric leaf gap” parameter was found to be critical for passing rates of VMAT plans. The source size parameter plays an important role as well for small fields. In the case of Pinnacle the multileaf collimator offset table needed to be optimized for better VMAT QA results. Each of the investigated treatment planning systems met the criteria to be used clinically in conjunction with Elekta Versa HD linear accelerators. It can be of great advantage to have the option to operate a TPS and linear accelerator from different vendors, as decisions surrounding linear accelerator or TPS purchases are very complicated and not just limited to technical considerations.

AbstractObjectivePatients with acquired autonomic dysfunction may have antibodies specific to the ganglionic nicotinic acetylcholine receptor (gAChR). However, the clinical features of children and adolescents with acquired autonomic dysfunction (AAD) remain unclear. This study aimed to determine the clinical features of pediatric patients with acquired autonomic dysfunction.MethodsThis study retrospectively examined a series of patients of AAD with serum gAChR antibodies who were referred to our laboratory for antibody testing between January 2012 and April 2019. The study included 200 patients (<20 years, 20 cases; ≥20 years, 175 cases) with clinical features of AAD.ResultsUpon comparing pediatric and adult patients, we found that antecedent infection and autonomic symptoms at onset with gastrointestinal symptoms occurred more frequently in children with AAD. We confirmed that four children (20.0%) met the diagnostic criteria for postural orthostatic tachycardia syndrome (POTS). A significantly higher number of children than adults had POTS (P = 0.002). In addition, upper GI dysfunction was more prevalent in children than in adults (P = 0.042). In particular, nausea and vomiting occurred in 60.0% of children with AAD and in 21.1% of adults (P < 0.001). The frequency of paralytic ileus was significantly higher in children with AAD (20.0%) relative to adults (6.3%) (P = 0.030). Regarding extra‐autonomic manifestations, encephalopathy was more frequent in children (15.0%) than in adults (1.1%) (P < 0.001).InterpretationPediatric AAD patients have their own clinical characteristics, and these features may be unique to children and adolescents.

Published: February 2021

ObjectiveTo determine the validity of self‐reported physician diagnosis of rheumatoid arthritis (RA) using multiple gold‐standard measures based on Medicare claims in a nationally representative sample of older adults and to verify whether additional questions about taking medication and having seen a physician in the past two years for arthritis can improve the positive predictive value (PPV) and other measures of the validity of self‐reported RA.MethodsA total of 3768 Medicare‐eligible respondents with and without incident self‐reported RA were identified from the 2004, 2008, and 2012 waves of the United States Health and Retirement Study. Self‐reported RA was validated using the following three claims‐based algorithms:1) a single International Classification of Diseases, ninth edition, Clinical Modification claim for RA,2) two or more claims no greater than 2 years apart, and3) two or more claims with at least one diagnosis by a rheumatologist. Additional self‐report questions of medication use and having seen a doctor for arthritis in the past two years were validated against the same criteria.ResultsA total of 345 respondents self‐reported a physician diagnosis of RA. Across all three RA algorithms, the PPV of self‐report ranged from 0.05 to 0.16., the sensitivity ranged from 0.23 to 0.55., and the κ statistic ranged from 0.07 to 0.15. Additional self‐report data regarding arthritis care improved the PPV and other validity measures of self‐report; however, the values remained low.ConclusionMost older adults who self‐report RA do not have a Medicare claims history consistent with that diagnosis. Revisions to current self‐reported RA questions may yield more valid identification of RA in national health surveys.

AbstractRechargeable batteries with Li‐metal anodes and Ni‐rich LiNixMnyCozO2 (x + y + z = 1, NMC) cathodes promise high‐energy‐density storage solutions. However, commercial carbonate‐based electrolytes (CBEs) induce deteriorative interfacial reactions to both Li‐metal and NMC, leading to Li dendrite formation and NMC degradation. Moreover, CBEs are thermally unstable and flammable, demonstrating severe safety risks. In this study, an ultrathin and non‐flammable dual‐salt polymer electrolyte (DSPE) is proposed via lightweight polytetrafluoroethylene scaffold, poly(vinylidene fluoride‐co‐hexafluoropropylene) polymeric matrix, dual‐salt, and adiponitrile/fluoroethylene carbonate functional plasticizers. The as‐obtained DSPE exhibits an ultralow thickness of 20 µm, high room temperature ionic conductivity of 0.45 mS cm−1, and a large electrochemical window (4.91 V versus Li/Li+). The dual‐salt synergized with functional plasticizers is used to fabricate a stable interface layer on both anode and cathode. In‐depth experimental and theoretical analyses have revealed the formation of stable interfaces between the DSPE and the anode/cathodes. As a result, the DSPE effectively prevents Li/DSPE/Li symmetric cell from short‐circuiting after 1200 h, indicating effective suppression of Li dendrites. Moreover, the Li/DSPE/NMC cell delivers outstanding cyclic stability at 2 C, maintaining a high capacity of 112 mAh g−1 over 1000 cycles.

Published: February 2021

AbstractBiostable electronic materials that can maintain their super mechanical and conductive properties, even when exposed to biofluids, are the fundamental basis for designing reliable bioelectronic devices. Herein, cellulose‐derived conductive 2D bio‐nanosheets as electronic base materials are developed and assembled into a conductive hydrogel with ultra‐high biostability, capable of surviving in harsh physiological environments. The bio‐nanosheets are synthesized by guiding the in situ regeneration of cellulose crystal into a 2D planar structure using the polydopamine‐reduced‐graphene oxide as supporting templates. The nanosheet‐assembled hydrogel exhibits stable electrical and mechanical performances after undergoing aqueous immersion and in vivo implantation. Thus, the hydrogel‐based bioelectronic devices are able to conformally integrate with the human body and stably record electrophysiological signals. Owing to its tissue affinity, the hydrogel further serves as an “E‐skin,” which employs electrotherapy to aid in the faster healing of chronic wounds in diabetic mice through transcutaneous electrical stimulation. The nanosheet‐assembled biostable, conductive, flexible, and cell/tissue affinitive hydrogel lays a foundation for designing electronically and mechanically reliable bioelectronic devices.
Manipulating Complementarity of Binary White Thermally Activated Delayed Fluorescence Systems for 100% Exciton Harvesting in OLEDs

Published: February 2021

AbstractDifferent to fluorescent and phosphorescent counterparts, white thermally activated delayed fluorescence (TADF) involves in multiple reverse intersystem crossing (RISC), leading to the correlation but competition between blue and other color components in both singlet and triplet allocations. Herein, three blue TADF emitters SSFAPO, DSFAPO, and TSFAPO, collectively named xSFAPO are developed, featuring a moderately electron‐withdrawing phosphine oxide (PO) acceptor respectively linked 1‐3 donors. Despite nearly identical blue emissions, photoluminescence quantum yields of xSFAPO are proportional to donor number. But, their RISC efficiencies are below 70%, markedly less than 85% of a conventional yellow TADF emitter 2,3,5,6‐tetrakis(3,6‐di‐(tert‐butyl)carbazol‐9‐yl)‐1,4‐dicyanobenzene (4CzTPNBu). Furthermore, sp3 hybrid configuration of PO enlarges steric hindrance of peripheral donor groups. So, Dexter energy transfer is impeded by increasing donor numbers. Among xSFAPO and 4CzTPNBu dually doped white‐emitting films, yellow emission from SSFAPO‐based film is the strongest, reflecting the predominance of fast Dexter energy transfer in triplet allocation. Therefore, SSFAPO endowed its warm‐white organic light‐emitting diodes (WOLEDs) with an external quantum efficiency of 25.1%, corresponding to 100% internal quantum efficiency, which are 1.25 and 1.60 folds of those of DSFAPO and TSFAPO‐based WOLEDs. These results suggest advantage complementarity of different components is crucial for developing white‐emitting systems with 100% exciton utilization.
