El objetivo de este estudio consistió en examinar las propiedades psicométricas del “Cuestionario de Experiencias de Recuperación” para su uso en Argentina. La muestra estuvo compuesta por 505 trabajadores provenientes del sector público, privado y organizaciones no gubernamentales. Los resultados del análisis factorial confirmatorio evidenciaron que un modelo de cuatro factores ─distanciamiento psicológico del trabajo, relajación, búsqueda de retos y control sobre el tiempo libre─ presentó un buen ajuste a los datos. Por lo tanto, el cuestionario mantiene la misma estructura que la escala original. Los análisis de confiabilidad mostraron que la escala posee una adecuada consistencia interna (α = .75 - .92) y fiabilidad de constructo (H = .88 - .93). Se obtuvieron correlaciones teóricamente esperadas con medidas de burnout, work engagement y afecto negativo, aportando de esta manera evidencias externas de validez concurrente. En conclusión, la escala posee adecuadas propiedades psicométricas para ser utilizada en el contexto argentino, permitiendo disponer de un instrumento confiable que permite profundizar el conocimiento sobre la recuperación y brindando una herramienta valiosa para la práctica profesional.
The aim of this study was to examine the psychometric properties of the Recovery Experience Questionnaire in Argentina. Five-hundred and five workers from public, private and non-governmental sectors participated in the study. Confirmatory factor analysis showed that the four-factor model has acceptable fit to the data. Thus, as the original scale, the Argentinean validation maintain the four recovery experiences—psychological detachment from work, relaxation, mastery experiences and control over leisure time. Reliability analyses showed good internal consistency (Cronbach’s α ranging from .75 to .92) and construct reliability (coefficient H ranging from .88 to .93) for all subscales. Correlations theoretically expected with measures of work engagement, burnout and negative affect supported for concurrent validity. Thus, the Recovery Experience Questionnaire shows adequate psychometric properties for its use in Argentina, make available a reliable instrument that allows deepening knowledge about recovery and providing a valuable tool for professional practice.

Determinadas variables psicológicas y la personalidad son consideradas como factores predisponentes o influyentes para el posterior desarrollo de los trastornos de la conducta alimentaria, así como también la puesta en práctica de determinados comportamientos de riesgo, como los atracones, vómitos o la práctica de ejercicio físico excesivo para la pérdida de peso. El objetivo del estudio fue comparar las diferencias en personalidad y variables psicológicas relevantes relacionadas con los TCA, en mujeres y hombres, a partir del cumplimiento de criterios específicos a partir de los cuales se recomienda la derivación a un especialista en patologías alimentarias. En el estudio participaron 604 estudiantes universitarios, y se emplearon el Inventario de Trastornos de la Conducta Alimentaria (EDI-3) y su cuestionario de remisión (EDI-3 RF), y el Five-Factor Inventory (NEO-FFI). Los resultados mostraron que hasta el 58.5% de mujeres y 49.5% de hombres cumplen criterios de remisión. Tanto en mujeres como en hombres, existen diferencias entre los grupos con criterios y quienes no los presentan, principalmente en neuroticismo, obsesión por la delgadez, bulimia, insatisfacción corporal y ascetismo. Las puntuaciones en el factor neuroticismo y en la gran mayoría de escalas psicológicas son también superiores en los sujetos que cumplen con mayor número de criterios.
Certain psychological variables and personality are considered as predisposing or influential factors for the subsequent development of eating disorders. Also the implementation of some risk behaviors, such as binge eating, vomiting or excessive physical exercise for weight loss. The objective of the study was to compare the differences in personality and relevant psychological variables related to eating disorders, in women and men, based on compliance with specific criteria to help identify individuals with potential eating disorders. Participants were 604 university students. The Eating Disorder Inventory-3 (EDI-3) and referral form (EDI-3 RF), and the Five-Factor Inventory (NEO-FFI) were used. The results showed that up to 58.5% of women and 49.5% of men met remission criteria. In both women and men, there are differences between groups with criteria and those who do not, mainly in neuroticism, drive for thinness, bulimia, body dissatisfaction and asceticism. The scores in the neuroticism factor and in the great majority of psychological scales are also higher in the subjects that accomplish the highest number of criteria.

The Presented study is an attempt to examine the trend and instability in area, production and productivity of food grain crops in Haryana and India during period 1966-67 to 2012-13 and five sub periods i.e. P-I (1966-67 to 1975-76), P-II (1976-77 to 1985-86), P-III (1986-87 to 1995-96), P-IV (1996-97 to 2005-06) and P-V (2006-07 to 2012-13). The study is based on secondary data. The study reveals positive trends in area, production and yield of food grains for both Haryana and India. Production in Haryana and India increased mainly due to increase in yield. Similar results have been obtained on triennium bases. In Haryana, area, production and yield have shown positive growth rates in all the periods and the overall period except for area in Period-III, IV and V. In the case of India positive growth rates has obtained for production and yield of food grains while area has shown negative trend in Periods III, IV, V and entire period under study. The coefficient of variation (C.V.) in respect of the three components i.e. area, production and productivity of total food grains found to be higher in Haryana as compared to India in all the periods and the overall period except for yield in period-III, yield and production in period-IV and yield in Period-V. Similar results have been obtained for the instability indices.

<p>O objetivo deste artigo é compreender o humor e o riso como uma dimensão possível, quiçá necessária, do processo educativo, sobretudo por sua potência crítico-criativa. Acreditamos que essa potência reside não só em sua qualidade de tornar o processo educativo mais leve e agradável, mas especialmente em sua capacidade de fazer vacilar o estabelecido (a sociedade capitalista), o sedimentado (a cultura burguesa), criando, assim, aberturas, deslocamentos e rupturas no seio do real, da ordem social e pedagógica vigente.</p><p> </p>

AbstractFor the development of wearable electronics, the replacement of rigid, metallic components with fully elastomeric materials is crucial. However, current elastomeric electrodes suffer from low electrical conductivity and poor electrical stability. Herein, a metal‐like conductive elastomer with exceptional electrical performance and stability is presented, which is used to fabricate fully elastomeric electronics. The key feature of this material is its wrinkled structure, which is induced by in situ cooperation of solvent swelling and densely packed nanoparticle assembly. Specifically, layer‐by‐layer assembly of metal nanoparticles and small‐molecule linkers on elastomers generates the hierarchical wrinkled elastomer. The elastomer demonstrates remarkable electrical conductivity (170 000 and 11 000 S cm−1 at 0% and 100% strain, respectively), outperforming previously reported elastomeric electrodes based on nanomaterials. Furthermore, a fully elastomeric triboelectric nanogenerator based on wrinkled elastomeric electrode exhibits excellent electric power generation performance due to the compressible, large contact area of the wrinkled surface during periodic contact and separation.

AbstractBackgroundNight shift work is associated with cardiovascular disease, but its associations with cardiovascular disease biomarkers are unclear. We investigated these associations in a study of female nurses.MethodsWe used data from the Nurses’ Health Study II for total cholesterol, low‐density lipoprotein cholesterol, high‐density lipoprotein (HDL) cholesterol, triglycerides, C‐reactive protein (CRP), and fibrinogen. The sample sizes for our analysis ranged from 458 (fibrinogen) to 3574 (total cholesterol). From questionnaires, we determined the number of night shifts worked in the 2 weeks before blood collection and total years of rotating night shift work. We used quantile regression to estimate differences in biomarker levels by shift work history, adjusting for potential confounders.ResultsNurses working 1 to 4 recent night shifts had median HDL cholesterol levels 4.4 mg/dL (95% confidence interval [CI]: 0.3, 7.5) lower than nurses without recent night shifts. However, working ≥5 recent night shifts and years of rotating night shift work were not associated with HDL cholesterol. There was no association between recent night shifts and CRP, but median CRP levels were 0.1 (95% CI: 0.0, 0.2), 0.2 (95% CI: 0.1, 0.4), and 0.2 (95% CI: 0.0, 0.4) mg/L higher among nurses working rotating night shifts for 1 to 5, 6 to 9, and ≥10 years compared with nurses never working rotating night shifts. These associations were attenuated when excluding postmenopausal women and women taking statins. We observed no associations between night shift work and other biomarkers.ConclusionsWe found suggestive evidence of adverse short‐term and long‐term effects of night shift work on select cardiovascular disease biomarkers.

AbstractCantú syndrome (CS), first described in 1982, is caused by pathogenic variants in ABCC9 and KCNJ8, which encode the regulatory and pore forming subunits of ATP‐sensitive potassium (KATP) channels, respectively. Multiple case reports of affected individuals have described the various clinical features of CS, but systematic studies are lacking. To define the effects of genetic variants on CS phenotypes and clinical outcomes, we have developed a standardized REDCap‐based registry for CS. We report phenotypic features and associated genotypes on 74 CS subjects, with confirmed ABCC9 variants in 72 of the individuals. Hypertrichosis and a characteristic facial appearance are present in all individuals. Polyhydramnios during fetal life, hyperflexibility, edema, patent ductus arteriosus (PDA), cardiomegaly, dilated aortic root, vascular tortuosity of cerebral arteries, and migraine headaches are common features, although even with this large group of subjects, there is incomplete penetrance of CS‐associated features, without clear correlation to genotype.

Published: December 2019

AbstractThe first colloidal nanoparticle synthesis of the copper selenophosphate Cu3PSe4, a promising new material for photovoltaics, is reported. Because the formation of binary copper selenide impurities seemed to form more readily, two approaches were developed to install phosphorus bonds directly: 1) the synthesis of molecular P4Se3 and subsequent reaction with a copper precursor, (P‐Se)+Cu, and 2) the synthesis of copper phosphide, Cu3P, nanoparticles and subsequent reaction with a selenium precursor, (Cu‐P)+Se. The isolation and purification of Cu3P nanoparticles and subsequent selenization yielded phase‐pure Cu3PSe4. Solvent effects and Se precursor reactivities were elucidated and were key to understanding the final reaction conditions.

Published: December 2019

AbstractPeptidylprolyl isomerases (PPIases) catalyze cis/trans isomerization of prolines. The PPIase CypA colocalizes with the Parkinson's disease (PD)‐associated protein α‐synuclein in cells and interacts with α‐synuclein oligomers. Herein, we describe atomic insights into the molecular details of the α‐synuclein/CypA interaction. NMR spectroscopy shows that CypA catalyzes isomerization of proline 128 in the C‐terminal domain of α‐synuclein. Strikingly, we reveal a second CypA‐binding site formed by the hydrophobic sequence 47GVVHGVATVA56, termed PreNAC. The 1.38 Å crystal structure of the CypA/PreNAC complex displays a contact between alanine 53 of α‐synuclein and glutamine 111 in the catalytic pocket of CypA. Mutation of alanine 53 to glutamate, as found in patients with early‐onset PD, weakens the interaction of α‐synuclein with CypA. Our study provides high‐resolution insights into the structure of the PD‐associated protein α‐synuclein in complex with the most abundant cellular cyclophilin.

AbstractIncorporating nanoscale Si into a carbon matrix with high dispersity is desirable for the preparation of lithium‐ion batteries (LIBs) but remains challenging. A space‐confined catalytic strategy is proposed for direct superassembly of Si nanodots within a carbon (Si NDs⊂C) framework by copyrolysis of triphenyltin hydride (TPT) and diphenylsilane (DPS), where Sn atomic clusters created from TPT pyrolysis serve as the catalyst for DPS pyrolysis and Si catalytic growth. The use of Sn atomic cluster catalysts alters the reaction pathway to avoid SiC generation and enable formation of Si NDs with reduced dimensions. A typical Si NDs⊂C framework demonstrates a remarkable comprehensive performance comparable to other Si‐based high‐performance half LIBs, and higher energy densities compared to commercial full LIBs, as a consequence of the high dispersity of Si NDs with low lithiation stress. Supported by mechanic simulations, this study paves the way for construction of Si/C composites suitable for applications in future energy technologies.

Published: December 2019

AbstractMetal–CO2 batteries have attracted much attention owing to their high energy density and use of greenhouse CO2 waste as the energy source. However, the increasing cost of lithium and the low discharge potential of Na–CO2 batteries create obstacles for practical applications of Li/Na–CO2 batteries. Recently, earth‐abundant potassium ions have attracted considerable interest as fast ionic charge carriers for electrochemical energy storage. Herein, we report the first K–CO2 battery with a carbon‐based metal‐free electrocatalyst. The battery shows a higher theoretical discharge potential (E⊖=2.48 V) than that of Na–CO2 batteries (E⊖=2.35 V) and can operate for more than 250 cycles (1500 h) with a cutoff capacity of 300 mA h g−1. Combined DFT calculations and experimental observations revealed a reaction mechanism involving the reversible formation and decomposition of P121/c1‐type K2CO3 at the efficient carbon‐based catalyst.

AbstractIm Beitrag wird die Prognosefähigkeit eines numerischen Mehrebenen‐Modells für stahlfaserverstärkte Betonstrukturen aus hochfestem Beton anhand einer die Faser‐ und die Strukturebene umfassenden Testserie systematisch untersucht. Die experimentelle Studie umfasst Auszugsversuche an Dramix 3D 55/60 und 65/60 Fasern in hochfestem Beton mit unterschiedlichen Einbettungslängen und Neigungen zur Rissfläche auf der Mesoskala sowie Dreipunkt‐Biegezugversuche an gekerbten Balken mit drei stark unterschiedlichen Fasergehalten zur Abbildung des Strukturverhaltens. Das numerische Modell ist derart konzipiert, dass es die direkte Verfolgung des Einflusses der Entwurfsparameter wie Faserart, Faserorientierung, Fasergehalt und Betonfestigkeit auf die Strukturantwort ermöglicht. Hierzu werden Submodelle auf der Ebene der Einzelfaser zu Rissüberbrückungsmodellen in Abhängigkeit von Faserorientierung und Fasergehalt zusammengeführt und zum Zwecke numerischer Strukturanalysen in ein Finite‐Elemente‐Modell integriert. Die Validierung der Modelle für endverankerte Stahlfasern zeigt, dass die wesentlichen Interaktionsmechanismen zwischen Faser und hochfestem Beton für alle untersuchten Fälle (Faserorientierung, Einbettungslängen) wirklichkeitsnah abgebildet werden. Auf der Strukturebene zeigen die Ergebnisse der numerischen Simulationen auf Basis des Faserbetonmodells eine sehr gute Übereinstimmung für alle Fasergehalte, sowohl was die maximale Last als auch das Nachbruchverhalten betrifft.
Board gender diversity and environmental, social, and economic value creation: Does family ownership matter?

Published: December 2019

AbstractPrior literature on firm value creation for stakeholders has oversimplified and narrowed the concept of value down to “economic returns.” Although economic returns are fundamental to a firm's core stakeholders (i.e., shareholders), other legitimate stakeholders want “value” beyond economic returns. We define stakeholder value as the financial and nonfinancial returns a firm can offer to its legitimate stakeholders, and empirically investigate whether board gender diversity (BGD) improves our multidimensional measure of value. Using Thomson Reuters' ASSET4 data for U.K.‐listed firms available from Eikon for the period 2007–2017, we report a significant positive relationship between BGD and stakeholder value creation. In particular, BGD increases social and environmental value creation in addition to economic returns. Furthermore, our results suggest that even though gender‐diverse boards are associated with stakeholder value creation in family firms, this is only conspicuous for environmental value creation. The findings suggest that although female directors cater to the interests of broader stakeholder groups, family ownership causes them to mainly focus on environmental stakeholders. The study provides important implications for regulators, stakeholders, and academic scholars.

AbstractComprehensive investigation in motor neuron disease is vital not to miss a treatable differential diagnosis. Neuroborreliosis should be considered during an ALS work‐up. However, false‐positive CSF results do occur, and thus, results should be interpreted carefully in context of all clinical test results.
