El liderazgo inclusivo como estrategia para evitar el abandono escolar: opinión de las familias
Authors: Crisol Moya Emilio , Romero López Mª Asunción 
Published: July 2020

Hablar de inclusión a nivel de centro inevitablemente lleva consigo hablar de una relación activa y positiva entre familia y escuela. En esta línea, se ha constatado la importancia de la participación de las familias en los centros escolares y su consecuente mejora en el rendimiento académico del alumnado; considerándose un factor clave en la prevención del abandono escolar. Este artículo se centra en determinar la perspectiva de las familias respecto al liderazgo inclusivo desarrollado por los equipos directivos, tales como los procesos de apertura hacia la comunidad y acciones que promuevan la participación, cooperación y reflexión hacia la diversidad en pro de un aprendizaje para todos. Se trata de una investigación cuantitativa de carácter descriptivo; la muestra estuvo compuesta por familiares de alumnos (N = 150). Utilizamos como herramienta el cuestionario: “Liderando la Educación Inclusiva” (LEI-Q). Los resultados muestran que las familias consideran que sus equipos directivos han implantado “sustancialmente” la mayor parte de las acciones que contribuyen a que sus centros sean inclusivos, promoviendo estrategias que reduzcan el abandono escolar. De esta manera se hace notable la necesidad de involucrar a las familias, para garantizar el éxito educativo y estimular a finalizar los estudios obligatorios y a continuar con una formación posterior.
Talking about inclusion at a school level inevitably “involves an active and positive relationship between families and schools” (Simón, Giné y Echeita, 2016, p. 26). Along these lines, the importance of family participation in schools has been reported to lead to improvements in students’ academic performance, which, in turn, stands out as a key factor in the prevention of early school leaving. This article aims to determine the views of families on inclusive leadership measures developed by management teams, such as (i) opening the center to the community and the environment; and (ii) actions to encourage participation, address diversity, and prevent and manage conflict in centers so that learning can be for everybody. This is a descriptive quantitative investigation. In this sense, our sample is composed of students’ relatives (N = 150), who were asked to complete the questionnaire “Leading Inclusive Education” (LEI-Q) (León et al., 2016). This research is an ex post-facto cross-sectional investigation of a descriptive nature. The results obtained indicate that families perceive the efforts made by school management teams to foster inclusive schools, which, in turn, promotes strategies that reduce school dropout. In this way, it is essential to involve families in order to guarantee educational success and stimulate students’ completion of compulsory education and to continue their further training.

Published: July 2020

La resiliencia es un concepto que en los últimos años está teniendo cada vez mayor presencia en los ámbitos sociales y educativos de nuestro país. Aunque su uso es relativamente reciente en el contexto español, sin embargo es un concepto que viene siendo utilizado desde el ámbito de la práctica profesional y avalado por numerosas investigaciones en el contexto anglosajón. Este trabajo tiene como objetivo estudiar la evolución que este concepto ha tenido durante las últimas décadas. Este análisis pone de manifiesto que la resiliencia es un tópico controvertido y en plena construcción. En efecto, los resultados del estudio bibliográfico y conceptual sobre la resiliencia muestran la evolución que ha tenido el tema en las tres últimas décadas desde un enfoque de la resiliencia centrado en el individuo y las cualidades de la persona resiliente, hacia un enfoque más socioeducativo, que se preocupa por comprender todos los elementos culturales y comunitarios que emergen e interactúan en los procesos resilientes. A partir de todo este análisis, el artículo arroja algunas conclusiones para repensar y actualizar el modo de abordar las prácticas e investigaciones sobre resiliencia.
Resilience is a concept that in recent years has had an ever-increasing presence in social and educational settings in Spain. Although its use is relatively recent in the Spanish context, it has been used in professional practice and supported by extensive research in the English-speaking context. This paper aims to study the evolution of this concept over the last decades. Our analysis found that resilience is a controversial topic and is still being constructed. The outcomes of the literature review and the conceptual study on resilience showed that this issue has been evolving over the last three decades, moving from an individual-based approach to resilience, focused on the qualities of a resilient person, towards a more socio-educational focus, concerned with understanding all the cultural and community-based elements that emerge and interact in resilience processes. From this analysis, the paper delimits some conclusions aimed at rethinking and updating how resilience practices and research are addressed.
Bioclaustration in Devonian fenestrate bryozoans. The ichnogenus Caupokeras McKinney, 2009
Authors: Suárez Andrés Juan L 
Published: July 2020

The ichnogenus Caupokeras is the only reported case of bioclaustration in which a symbiont is enveloped by fenestrate bryozoans. In this paper, type and additional material of Caupokeras from Belgium, Germany and Spain is revised and the number of bryozoan genera on which it occurs is expanded; a possible case from the Carboniferous of the USA is discussed and an expanded description of the ichnogenus and a palaeobiological interpretation are provided. The association between the fenestrate bryozoans and the sclerobionts that gave rise to this trace seems to have been more advantageous for the latter

Aims
The study aimed to explore factors contributing to body weight change over time in gastric cancer patients after gastrectomy, in order to find risk factors to implement nutritional intervention beforehand.

Methods
A cohort of gastric cancer patients who were treated with gastrectomy from January to March 2019 at a university affiliated hospital in Shanghai were consecutively identified in this study. Demographics, disease related information, nutrition knowledge, attitude, and practice score were collected before gastrectomy. In addition, body weight before surgery (T0), body weight at one month (T1), two months (T2), and three months (T3) after gastrectomy were recorded. Generalized estimation equation was used to describe body weight change and analyze factors contributing to body weight change after surgery.

Results
There were 49 patients recruited in the study. Patient body weight decreased by 9.2% at T1 (Wald χ = 271.173, P <0.001), 11.0% at T2 (Wald χ2 = 277.267, P <0.001), and 11.4% at T3 compared to baseline at T0 (Wald χ = 284.076, P <0.001). The results of GEE for multivariable analysis showed that surgery type (Wald χ = 6.027, P = 0.014) and preoperative BMI (Wald χ = 12.662, P = 0.005) were contributing factors of body weight change. Compared with distal gastrectomy patients, total gastrectomy patients experienced greater body weight loss (β = 2.8%, P = 0.014). Compared with patients with BMI&λτ; 18.5 kg/m2, patients with BMI ≥ 25 kg/m2experienced greater body weight loss (β = 4.5% P = 0.026).

Conclusion
Gastric cancer patients experienced significant weight loss during 3 months after gastrectomy. Total gastrectomy and BMI ≥ 25 kg/m2were risk factors to postoperative body weight loss for GC patients. The results suggested hinted that clinician should pay attention to postoperative nutrition status of patient undergoing total gastrectomy and obesity patients.

Recent Advances in Organocatalyst‐Mediated Benzannulation Reactions
Authors: Wu Lulu , Yu Bing , Li Er‐Qing 
Published: July 2020

AbstractAromatic compounds are omnipresent in organic chemistry, which are the broadest skeletons of bioactive molecules, medicines, and materials. Due to their importance, conventional methods to assemble aromatic rings have attracted considerable attention. The direct formation of benzene cores from readily available acyclic precursors offers a highly versatile and superior approach to prepare both small organic molecules and sophisticated natural products. Recently, organocatalyst‐mediated annulation reaction, including phosphine‐, tertiary amine‐, secondary amine‐, primary amine‐, and NHC‐mediated benzannulation reactions, is considered as an efficient method to access multi‐substituted arenes. In this review, we will emphasize the selected examples of organocatalyst‐mediated benzannulation reactions of available acyclic precursors for the construction of diverse aromatics.magnified image
Assessment of the Performance of Optimally Tuned Range‐Separated Hybrid Functionals for Nuclear Magnetic Shielding Calculations
Authors: Prokopiou Georgia , Autschbach Jochen , Kronik Leeor 
Published: July 2020

AbstractThe performance of optimally tuned range‐separated hybrid (OT‐RSH) functional calculations in predicting accurate isotropic nuclear magnetic shielding (σ) and chemical shift values is examined. To that end, the results of OT‐RSH and other approximate density functional theory calculations are assessed against recently published benchmark CCSD(T) calculations for a test set consisting of several molecules and bond types. It is found that for atoms in single bonds with a large paramagnetic contribution to σ, OT‐RSH offers a significant improvement in prediction of shielding constants over popular semi‐local and hybrid density functionals, yielding non‐empirical results that are as accurate as those of semi‐empirical density functionals often used for prediction of shielding constants. This success is attributed to the improved fundamental gap prediction of the OT‐RSH approach. For atoms in multiple bonds, however, larger errors often persist. By comparing OT‐RSH and recently reported double‐hybrid functional results, the remaining difficulties are traced to significant non‐local correlation.

AbstractNanohybrid superconducting junctions using antimony telluride (Sb2Te3) topological insulator nanoribbons and Nb superconducting electrodes are fabricated using electron beam lithography and magnetron sputtering. The effects of bias current, temperature, and magnetic field on the transport properties of the junctions in a four‐terminal measurement configuration are investigated. Two features are observed. First, the formation of a Josephson weak‐link junction. The junction is formed by proximity‐induced areas in the nanoribbon right underneath the inner Nb electrodes which are connected by the few tens of nanometers short Sb2Te3 bridge. At 0.5 K a critical current of 0.15 µA is observed. The decrease of the supercurrent with temperature is explained in the framework of a diffusive junction. Furthermore, the Josephson supercurrent is found to decrease monotonously with the magnetic field indicating that the structure is in the small‐junction limit. As a second feature, a transition is also observed in the differential resistance at larger bias currents and larger magnetic fields, which is attributed to the suppression of the proximity‐induced superconductive state in the nanoribbon area underneath the Nb electrodes.

Published: July 2020

AbstractAs an emerging member of the graphene family, structurally defined graphene nanoribbons (GNRs) have shown promising applications in various fields. The evaluation of the degradability of GNRs is particularly important for assessing the persistence level and risk of these materials in living organisms and the environment. However, there is a void in the study of the degradation of GNRs. Here, we report the degradation behavior of GNRs in the presence of human myeloperoxidase (hMPO) or treated with the photo‐Fenton (PF) reaction. With the assistance of potassium hydroxide or imidazole, which facilitates the dispersion of GNRs in the aqueous solution, GNRs underwent only partial degradation after 25‐hour incubation with hMPO, while, the PF reaction degraded GNRs almost completely after 120 hours. These results indicate that structurally precise GNRs can be efficiently degraded under suitable conditions, providing more opportunities for future applications in different fields.

AbstractThe nucleation kinetics of the alpha form of p‐aminobenzoic acid from ethanolic and aqueous solutions is examined through a comparative examination of temperature‐jump and anti‐solvent drown‐out isothermal crystallization methodologies. Analysis of the data reveals the measured induction times, and the calculated effective interfacial tensions as a function of the supersaturation show broadly equivalent behavior for the aqueous‐ethanol mixed‐solvent drown‐out and temperature‐jump ethanol solution systems, confirming the comparability of the two methodologies. The results also demonstrate poorer agreement with the temperature‐jump pure aqueous system, highlighting the importance of the strength of solvation/desolvation as the key rate‐limiting process for the overall nucleation behavior.

Published: July 2020

AbstractTritopic ion‐pair receptors can bind bivalent salts in solution; yet, these salts have a tendency to form ion‐pairs even in the absence of receptors. The extent to which such receptors can enhance ion pairing has however remained elusive. Here, we study ion pairing of M2+ (Ba2+, Sr2+) and X− (I−, ClO4−) in acetonitrile with and without a dichlorooxacalix[2]arene[2]triazine‐related receptor containing a pentaethylene‐glycol moiety. We find marked ion association already in receptor‐free solutions. When present, most of the MX+ ion‐pairs are bound to the receptor and the overall degree of ion association is enhanced due to coordinative, hydrogen‐bonding, and anion‐π interactions. The receptor shows higher selectivity for iodides but also stabilizes perchlorates, despite the latter are often considered as weakly coordinating anions. Our results show that ion‐pair binding is strongly correlated to ion pairing in these solutions, thereby highlighting the importance of taking ion association in organic solvents into account.
Ecological niche models display nonlinear relationships with abundance and demographic performance across the latitudinal distribution of Astragalus utahensis (Fabaceae)
Authors: Baer Kathryn C. , Maron John L. 
Published: July 2020

AbstractThe potential for ecological niche models (ENMs) to accurately predict species' abundance and demographic performance throughout their geographic distributions remains a topic of substantial debate in ecology and biogeography. Few studies simultaneously examine the relationship between ENM predictions of environmental suitability and both a species' abundance and its demographic performance, particularly across its entire geographic distribution. Yet, studies of this type are essential for understanding the extent to which ENMs are a viable tool for identifying areas that may promote high abundance or performance of a species or how species might respond to future climate conditions. In this study, we used an ensemble ecological niche model to predict climatic suitability for the perennial forb Astragalus utahensis across its geographic distribution. We then examined relationships between projected climatic suitability and field‐based measures of abundance, demographic performance, and forecasted stochastic population growth (λs). Predicted climatic suitability showed a J‐shaped relationship with A. utahensis abundance, where low‐abundance populations were associated with low‐to‐intermediate suitability scores and abundance increased sharply in areas of high predicted climatic suitability. A similar relationship existed between climatic suitability and λs from the center to the northern edge of the latitudinal distribution. Patterns such as these, where density or demographic performance only increases appreciably beyond some threshold of climatic suitability, support the contention that ENM‐predicted climatic suitability does not necessarily represent a reliable predictor of abundance or performance across large geographic regions.

Published: July 2020

AbstractThis paper describes the development of a label‐free electrochemical immunosensor based on polyethyleneimine‐stabilized magnetite nanoparticles (MGNnP‐PEI) for the determination of microcystin‐LR (MC‐LR). MGNnP‐PEI was immobilized on the glassy carbon electrode (GCE) surface and employed as a platform for anchorage of the anti‐MC‐LR. Hydroquinone in solution was used as a redox probe. After optimization, the immunosensor exhibited a linear response to MC‐LR concentrations in the range of 0.1 to 500 ng mL−1 with a calculated detection limit of 0.053 ng mL−1. The immunosensor was satisfactorily applied in the quantification of MC‐LR in a water sample collected from a freshwater lagoon.

Published: July 2020

AbstractA gold microelectrode (10 μm diameter) with an electropolymerized layer of poly(3,4‐ethylenedioxythiophene) (PEDOT) was used to quantify uric acid and investigate the antioxidant profile of milk and flavored milks. Comparisons were made with a bare gold microelectrode and a PEDOT‐glassy carbon macroelectrode (3 mm diameter). Two different electropolymerization processes were undertaken in an aqueous and an organic solution, and superior polymer growth was observed for PEDOT polymerized in lithium perchlorate/propylene carbonate. In the presence of a ferri/ferrocyanide redox couple, diffusion‐controlled redox peaks were observed with the PEDOT‐gold microelectrode rather than the plateau current typical of a bare microelectrode. Likewise, an anodic peak for uric acid was observed at the high surface‐area PEDOT‐gold microelectrode, with evidence for pre‐adsorption of uric acid at the electrode. The linear concentration range for uric acid standards was from 6 to 200 μM, and the limit of detection, limit of quantification, and sensitivity were determined to be 7 μM, 24 μM, and 397 μAμM−1cm2, respectively. Cyclic voltammograms of chocolate and espresso flavored milks exhibited significant contributions from the phenolic compounds present. Peak separation was more clearly defined using the PEDOT‐microelectrode compared to a PEDOT‐glassy carbon macroelectrode.

AbstractHydrogen production from water splitting is a widely used technique and hematite is one of the most used semiconductors in these processes due to its favorable characteristics such as: adequate band gap, visible light absorption, high chemical stability, abundance in nature, among others. Research on hydrogen fuel production from ammonia instead of water is still very limited. Ammonia is a contaminant normally found in wastewater and annualy tons of ammonia or effluents containing this contaminant are thrown into the environment, making it an ideal reagent to produce hydrogen in a clean environmental process. Based on this knowledge, this work proposes the comparison of the photoelectrochemical performance of hematite doped with structural cations (zinc, copper, cobalt, and nickel) in the molecular fragmentation of water and ammonia to produce hydrogen. A structural characterization of the materials used and tests for PEC activity were performed. Pure hematite doped with ammonia as a substrate presented higher electrical current and it was not activated by visible light. When under visible light hematite‐Co presented a discrete increase in the electrical current and, consequently, a small increase in the hydrogen production from water, whereas in the tests with ammonia, the copper‐doped hematite was responsible for a slight increase in the electrical current.
