El Espacio Europeo de Educación Superior y la figura del profesor tutor en la universidad
Authors: García González Alfonso Javier , Troyano Rodríguez Yolanda 
Published: November 2018

<p><span style="font-family: Arial; font-size: x-small;">Disponemos de una serie de argumentos que justifican la adopción de una posición favorable a la tutorización del alumnado universitario. En primer lugar, la tutoría ayuda a resolver las dificultades que plantea la mayor heterogeneidad del alumnado, debida a una mayor diversificación del acceso a la Universidad. En segundo lugar, facilita la orientación curricular ligada a las salidas profesionales y al acceso a otros estudios, así como garantiza la transparencia y la comparabilidad exigidas por el Espacio Europeo de Educación Superior. En tercer lugar, contribuye a atender a los estudiantes que tienen dificultad para lograr un seguimiento regular de los estudios. Y en cuarto lugar, mejora la imagen pública y la proyección externa de la Universidad, así como la fidelización de los estudiantes, y ofrece opiniones que facilitan el aprendizaje a lo largo de la vida. Por lo que respecta a los </span><em style="font-family: Arial; font-size: x-small;"> objetivos </em><span style="font-family: Arial; font-size: x-small;">que nos planteamos, por un lado, analizaremos cuáles son los roles y competencias que definen el perfil de un profesor-tutor ideal; asimismo, estableceremos un marco global de actuación que responda a las necesidades emergentes de los estudiantes a lo largo de la formación académica; así como dotar al alumnado de estímulos para el desarrollo de la reflexión, el diálogo, la autonomía y la crítica en el ámbito académico; para lo que esbozaremos un análisis cuantitativo y cualitativo acerca de cómo perciben las tutorías los estudiantes de pedagogía.</span></p><p> </p>

Authors: Oliveira Rodrigo Oliveira de , Acadrolli Aline Bernardi 
Published: November 2018

http://dx.doi.org/10.5007/1984-6924.2016v13n1p115Este artigo apresenta uma reflexão acerca de como se dá a relação dos usuários com newsgames na internet. Foram abordados fundamentos de Jornalismo Online, Cultura Gamer, newsgames, cibercultura a partir de um estudo observação na internet de dois newsgames (Filosofighters e CSI - Ciência Contra o Crime)da página multimídia da Revista online Super Interessante do Grupo Abril. Foram analisados um total de 204 comentários publicados na página dos newsgames, no mês de novembro de 2015. O objetivo foi tentar perceber as interações dos jogadores com o ambiente que estão inseridos. Percebeu-se que os indivíduos, que orbitam neste espaço, se autorreconhecem, se relacionam e fortalecem a identidade de comunidade virtual. Nota-se que as mecânicas do jogo são os fatores que mais chamam a atenção dos jogadores, porém muitos vão além do “jogar” e analisam o cobnteúdo, aprendem e materializam suas experiências e ideologias nesse contexto.

La CONAMURI: resistencia de mujeres rurales e indígenas en Paraguay
Authors: Ramos Marco Enrique Gonzalez 
Published: November 2018

La Coordinadora Nacional de Organización de Mujeres Trabajadoras, Rurales e Indígenas (CONAMURI) es una organización autónoma de mujeres que actúa de forma independiente al movimiento campesino e indígena de Paraguay. Entender por qué ellas decidieron construir un espacio propio para luchar por sus reivindicaciones así como la constitución de género, clase y etnia como base de su organización son claves que permiten conocer el impacto de los ejes de desigualdad de nuestra sociedad que se entrecruzan en ellas. La teoría feminista y la poscolonial, con aportes desde la perspectiva interseccional, son las herramientas de análisis utilizadas a fin de lograr una visión multicultural necesaria para comprender el contexto de la lucha de estas mujeres indígenas y campesinas.

Micropolíticas de exclusão: as dificuldades no acesso e permanência das pessoas trans na educação
Authors: Oliveira André Lucas Guerreiro 
Published: November 2018

Pretende-se discutir neste artigo as dificuldades que as pessoas trans apresentam para o acesso e a permanência nos ambientes educacionais. É de amplo conhecimento que a transfobia – violência, preconceito e discriminação que as pessoas trans sofrem – é causadora de grandes dificuldades e desafios na vida destas pessoas, em todos os espaços de convivência, e não seria diferente nas instituições de ensino. Infelizmente, na escola também se aprende e ensina como reproduzir preconceitos e desrespeito às diferenças. O ambiente escolar e o universitário muitas vezes chegam a ser tão hostis às pessoas trans que é frequente a desistência precoce dos estudos. Ainda hoje (mesmo que haja avanços) é incomum a cena de uma pessoa trans que concluiu o ensino superior; ao ponto de que a notícia de uma mulher ou um homem trans finalizando uma pós- graduação, ganha enorme repercussão e notoriedade principalmente nos meios de divulgação nas mídias digitais, como as redes sociais. Neste sentido, o trabalho almeja problematizar estas dificuldades denominando- as como micropolíticas de exclusão, a partir de um referencial foucaultiano. Tais micropolíticas são produzidas nos espaços educacionais e geram desconforto e adversidades para as pessoas trans, obrigando-as muitas vezes a abandonarem os estudos. Salienta-se que se existem poucas políticas de acesso, as políticas para a permanência ainda são incipientes e precárias. Palavras-Chave: Pessoas trans. Educação. Acesso e permanência.
Richness of Dendrocephalus (Branchiopoda, Anostraca) in Brazil with the description of two new species
Authors: Rabet Nicolas , Lacau Sébastien , Bozelli Reinaldo L. 
Published: November 2018

We present an overview of the morphological diversity and geographical distribution of the anostracan genus Dendrocephalus Daday, 1908, and describe two new species: D. aranai sp. nov. from Jequitinhonha in the state of Minas Gerais and D. xikrini sp. nov. from the Carajás Mountains (Serra dos Carajás) in the state of Pará. These species have important similarities to D. goiasensis Rabet & Thiéry, 1996 and D. thieryi Rabet, 2006, respectively, but differ from them and each other through a combination of characters that are essentially unique to the endopods, and frontal appendage branch 2A and branch 2D. We also partly redescribe D. carajaensis Rogers, Gomes & Vieira, 2012, which shows a particular intra-populational variability in branch 2A and 2D III of the frontal appendage, a type of polymorphism that was also recently observed in D. orientalis Rabet & Thiéry, 1996 and which must now be taken into account in taxonomy. In terms of the distribution of species of Dendrocephalus in Brazil, we suggest that several other species are probably present in the Amazonian, Cerrado and Pantanal Biomes, which remain largely unexplored. A new taxonomic key for the identification of males of the Brazilian species is provided.
Hybrid InSe Nanosheets and MoS2 Quantum Dots for High‐Performance Broadband Photodetectors and Photovoltaic Cells

Published: November 2018

AbstractHybrid structures‐based phototransistors are intensively studied recently to achieve high‐performance optoelectronic devices. The hybridization of 2D materials and quantum dots (QDs) is one of the ideal platforms for photodetection applications with the merits of high detection sensitivity and wide wavelength coverage. The broadband absorption of a hybrid device stems from various absorbers with multiple bandgaps to create high photocurrent from an efficient exciton generation mechanism under illumination. Here, a new optoelectronic hybrid device of an indium selenide (InSe) nanosheets‐based phototransistor is introduced decorated with molybdenum disulfide (MoS2) QDs to possess the photoresponsivity (Rλ) of 9304 A W−1, which is ≈103 times higher than Rλ ≈ 12.3 A W−1 of the previously reported InSe photodetector. The escalated Rλ of this hybrid photodetector is due to the additional injection of photoexcited charge carriers from MoS2 QDs to the InSe phototransistor. Finally, the photovoltaic performance of this MoS2/InSe hybrid device is investigated. The open‐circuit voltage (Voc) and short‐circuit current density (Jsc) are determined to be 0.52 V and 15.6 mA cm−2, respectively, rendering the photovoltaic efficiency of 3.03%. The development of this MoS2/InSe hybrid phototransistor with high device performance and wide wavelength photodetection will bring a new type of optoelectronic applications in the future.
Decolonial Pedagogy in Community Psychology: White Students Disrupting White Innocence via a Family Portrait Assignment
Authors: Fernández Jesica Siham 
Published: November 2018

AbstractA decolonizing standpoint in community psychology is discussed in relation to the Family Portrait Assignment—a pedagogical tool developed and implemented to facilitate white students’ decolonial thinking. The Family Portrait Assignment contributes to the limited of decolonial pedagogical tools in community psychology. Through a critical discourse analysis of student's essays, I discuss how decolonial thinking, including a critical sociohistorical examination of colonialism, racism and whiteness, was facilitated. Decoloniality as the disruption of white innocence, an ideological construct embedded within systems of power that sustain structures of whiteness, guides the analysis of student's essays. The purpose of this paper is to demonstrate how the Family Portrait Assignment facilitated white student's decolonial thinking, specifically their process of engaging with and disrupting white innocence. A discussion of decoloniality in community psychology pedagogy, theory, research and action concludes this paper.
Edwards Sapien 3 transcatheter aortic valve implantation for management of severe aortic regurgitation in a teenage patient with corrected atrioventricular septal defect and progressive left ventricular dysfunction
Authors: Lehner Anja , Herrmann Florian E. , Mehilli Julinda , Haas Nikolaus A. 
Published: November 2018

AbstractTranscatheter aortic valve replacement is mostly performed in elderly patients with severely calcified aortic valves. There are few reports about its use for pure aortic regurgitation, few reports about its use in adolescent patients and to the best of our knowledge no report about the use of an Edwards Sapien valve in the aortic position in an underage patient after surgically corrected congenital heart disease (CHD). Decompensation of a complex CHD can be difficult to manage and may require unusual solutions. We report a case of a teenage patient presenting with progressive aortic regurgitation and deterioration of left ventricular function after multiple surgical procedures for an atrioventricular septal defect (AVSD). As “bridge‐to‐transplant,” we performed a transcatheter aortic valve implantation using a balloon‐expandable Sapien 3 prosthesis. At 6 month follow‐up, the patient remained clinically stable with no rehospitalization due to heart failure.
Staged revascularization in patients with acute coronary syndromes due to saphenous vein graft failure and chronic total occlusion of the native vessel: A novel concept
Authors: Xenogiannis Iosif , Tajti Peter , Burke M. Nicholas , Brilakis Emmanouil S. 
Published: November 2018

AbstractPercutaneous coronary intervention of saphenous vein graft (SVG) lesions can be challenging due to high risk for acute and long‐term complications. Treating the corresponding native coronary artery lesion(s) is preferable, but may not be feasible in the acute setting, due to high technical difficulty, especially when the native coronary lesion is a chronic total occlusion (CTO). We describe a novel concept of “staged revascularization” in patients presenting with an acute coronary syndrome due to SVG failure, whose native coronary artery supplied by the SVG has a CTO. In the first stage, the culprit SVG lesion is treated restoring flow to the supplied myocardium and minimizing the extent of myocardial injury. During the second stage (typically few weeks later), revascularization of the corresponding native coronary artery lesion(s) is performed, often using the initially treated SVG for retrograde crossing of the native coronary artery CTO. We describe two cases of non‐ST segment elevation acute myocardial infarction due to SVG failure that were treated with “staged revascularization”: the culprit SVG was initially treated followed by staged revascularization of the corresponding native coronary artery CTO. Staged revascularization of SVG lesions causing acute coronary syndromes may allow optimization of both acute and long‐term outcomes.

Published: November 2018

AbstractThis work explores the syntheses, structures, photophysical properties, and photostability of benzodipyrenes (BDPs). BDPs were synthesized through an InCl3‐AgNTf2‐catalyzed, four‐fold alkyne benzannulation reaction. The structures of BDP 4 a and its corresponding endoperoxide product were unambiguously confirmed by X‐ray crystallography. The BDPs reported here can also be recognized as peri‐ and cata‐benzannulated pentacenes with a non‐functionalized central ring. Unlike the previous reported pentacene‐based polycyclic aromatic hydrocarbons, the absorbances of the BDPs were blueshifted by ca. 40 nm relative to pentacene, even after extension of π‐conjugation. The newly synthesized BDP products exhibit relatively good stability with half‐lives as high as 4612 min in THF.

Antireflection layers are commonly used in photovoltaics to increase light absorption and therefore increase maximum photocurrent. Here, pyramid structures are created on Si surfaces with alkaline solution etching. The extent of pyramid coverage depends directly on the reaction time and as a result, the surface reflectance decreases with reaction time. A floating transfer method is used to fabricate heterojunction solar cells based on graphene oxide‐carbon nanotube and Si heterojunctions. The best device performance (photo current conversion efficiency of 13.01 ± 0.32%, which is much higher than the efficiency of the control devices (10.18 ± 0.33%)) was observed using with cells fabricated with the highest coverage (99.9%) of pyramids on the Si surfaces, which is determined to be a combined effect of reduced surface reflectance and increased effective heterojunction area per unit active area.

Published: November 2018

AbstractMembranes are an integral component of guided bone regeneration protocols. This pre‐clinical study was aimed at enhancing the bioactivity of collagen membranes by incorporating plasmid DNA (pDNA) or chemically modified RNA (cmRNA) encoding bone morphogenetic protein‐9 (BMP‐9). In addition, we also endeavored to harness the regenerative potential of the periosteum by creating perforations in the membrane. Nanoplexes of polyethylenimine (PEI)‐nucleic acids (PEI‐pDNA or PEI‐cmRNA encoding BMP‐9) were incorporated into commercially obtained and perforated collagen membranes (PCM) to produce PCM‐pDNA(BMP‐9) or PCM‐cmRNA(BMP‐9). After structural characterization, the biodegradation kinetics of PCM, PCM‐pDNA(BMP‐9) and PCM‐cmRNA(BMP‐9) were assessed in simulated body fluid in vitro. Using a 24‐well transwell plate system with bone marrow stromal cells (BMSCs) in the lower chamber and the PCM to be tested in the upper chamber, the in vitro bioactivity of different PCMs was evaluated by measuring various markers for osteogenesis in BMSCs. Alkaline phosphatase activity was assessed in BMSCs, after 7 and 11 days of exposure to PCM, PCM‐pDNA(BMP‐9), or PCM‐cmRNA(BMP‐9). Similarly, calcium deposition and Alizarin red staining in BMSCs were assessed after 14 days of exposure to the three different types of PCM. PCMs were then tested in vivo using the calvarial defect model in rats. After 4 weeks, animals were euthanized and bone specimens were harvested for micro‐computed tomography and histological assessments. Incorporation of pDNA or cmRNA did not alter the biodegradation profile of PCMs. Alkaline phosphatase activity trended toward being higher in BMSCs exposed to PCM‐cmRNA(BMP‐9) or PCM‐pDNA(BMP‐9), when compared to BMSCs alone. Similar trends were observed when calcium deposition and alizarin red staining was evaluated. Calvarial bone defects treated with PCM‐cmRNA(BMP‐9) resulted in significantly higher bone volume/total volume % (BV/TV%), when compared to empty defects and trended toward being higher than defects treated with PCM‐pDNA(BMP‐9) and PCM alone. We demonstrate for the first time that resorbable PCM can be utilized to efficiently deliver pDNA and cmRNA of interest. The released pDNA and cmRNA encoding BMP‐9 in this assessment was shown to be functional in vitro as well as in vivo. © 2017 Wiley Periodicals, Inc.

Published: November 2018

IntroductionPericardial effusion (PE) is a complication of late‐stage cancer and some patients never leave the hospital despite drainage. The main objective of this study was to identify predictors of hospital discharge in cancer patients with (PE) who underwent pericardial drainage. We also report the occurrence of paradoxical hemodynamic instability (PHI).Methods and MaterialsA retrospective study was carried out in a cancer center. Patients included had malignancy, PE, and underwent surgical drainage. An institutional database was reviewed for preoperative variables, analyzed for hospital discharge.ResultsOne‐hundred and thirteen patients were included, with a mean age of 54 years old (SD 14.3). Sixty‐three patients were discharged from hospital (55.7%). Age (odds ratio [OR], 1.04; P = 0.004), higher ECOG status (OR, 0.63;
P = 0.019), recent chemotherapy (OR, 3.40;
P = 0.007), and renal failure (OR, 0.14;
P = 0.002) were associated with hospital discharge. Median survival was 43 days (IQ 25%‐75%; 15‐162). Patients with pulmonary embolism or neutropenia were at greater risk of developing PHI (OR, 10.11;
P = 0.009 and OR, 12.13;
P = 0.015, respectively).ConclusionAlmost half of the patients never left the hospital. Patients with no chemotherapy within 45 days of procedure, patients with renal failure and higher ECOG status are at greater risk of not getting discharged. PHI remains a serious condition with high mortality.
Cr(VI) oxidation using cetylpicolinium dichromate: Kinetics of oxidation of benzaldehydes with a green protocol
Authors: Priyadarshini Supriya , Dash Sukalyan 
Published: November 2018

AbstractOxidation kinetics of benzaldehyde and some of its ortho‐ and para‐monosubstituted derivatives have been studied using cetylpicolinium dichromates, a class of novel phase transfer oxidants, in dichloromethane medium. The rate of reaction is first order with respect to oxidant and fractional order with respect to the substrates. The Michaelis–Menten type oxidation was observed with respect to the substrates. Benzaldehydes are found to be oxidized to their corresponding acids. The mechanism of oxidation reaction has been suggested based on the solvent isotope effect, Hammett plot, and thermodynamic study. The solvent isotope effect (kCHCl3/kCDCl3 = 1.57) indicates the involvement of hydrogen exchange with the medium during oxidation reactions. A strong influence of specific solute–solvent interactions on the rate of the reaction is observed. Both the electron‐withdrawing and electron‐releasing substituents on the substrates accelerate the rate of reaction.
