Conservar, conversar y contestar. Grietas y relecturas del álbum familiar
Authors: Martín-Núñez Marta , García-Catalán Shaila , Rodríguez-Serrano Aarón
Published: July 2020

La fotografía es capaz, no de detener el tiempo, pero sí de retener instantáneas para que no debamos conservarlas solo en la memoria. Y es especialmente en el ámbito familiar en el que esta forma de representación se convierte en un amarre que permite soportar la angustia del paso del tiempo. Es la distancia entre el hecho fotográfico y la representación fotográfica lo que carga de potencia la fotografía familiar, generando un discurso avivado por la nostalgia del pasado, esto es: la experiencia de la pérdida. En este artículo analizamos trabajos fotográficos en los que la reelaboración desde la relectura del álbum familiar supone un acto artístico de contestación, conversación o de reescritura de lo que el álbum familiar creyó fijar. En el caso de los álbumes familiares —esta es nuestra hipótesis— la relectura permite un acto de reinterpretación y de cuestionamiento de la historia familiar y de las identificaciones que éstas promueven. Para adentrarnos en esta lectura de la fotografía familiar, trazaremos un recorrido basado en el análisis de casos paradigmáticos que parten de la fotografía personal y el álbum familiar para cuestionar sus estructuras internas de poder desde una metodología de corte semiótico (Marzal, 2007) que nos permite leer la imagen como materialidad significante donde queda plasmada la enunciación autoral. Abordaremos así el álbum de fotografía familiar como relato, como propaganda, como un significante ausente de forma, como una construcción de identificaciones, como un objeto fetiche y, en el paradigma postfotográfico, también como un discurso de la extimidad que supone un acto de contestación que permite conversaciones generacionales, una reflexión sobre la política de los cuerpos, los ideales, los objetos y las marcas subjetivas del tiempo.

Does Openness, and Productivity Matters for FDI: A Global Interactive Analysis Based on the Complementary Role of Institutions
Authors: Raffat Humaira , Siddiqui Danish Ahmed
Published: July 2020

Conventional wisdom suggested that investment flows in where you have abnormal returns that resulted in a high productivity area. However, FDI behaves peculiarly, as most are targeted towards developed countries where excess competition drives down returns and ultimately productivity. On the contrary, it shy in developing countries where one has more productive investment opportunities. This study tries to tackle the problem and explores the factors that influenced FDI flows. In particular, we focused on productivity, trade openness, financial liberalization, and institutions. Macro-level data was collected from 27 economies from 2004 to 2015. The analysis was done using GMM methodology. The results showed productivity remained insignificant in explaining FDI throughout the models. Trade seems to have a significant positive impact on the model without the interaction effect. Interestingly, financial liberalization seems to affect FDI negatively in all cases. GDP growth had a positive and significant effect. All Institutional variables that include control of corruption, government effectiveness, regulatory quality, rule of law, seems to have a significant positive impact on FDI individually, as well as in the combined form. We also witnessed significant and positive complementarities with each of the institutional factors and productivity, in explaining FDI. This indicated that higher productivity is not the deciding factor of FDI, however, the same productivity in a better institutional environment would produce positive complementarity that would significantly determine FDI. The findings imply that investors' prime concern is not productivity but the institutional environment. Moreover, only with quality institutions, the conventional wisdom persists.
Use of a Bipolar Vessel-Sealing Device for Splenic Parenchymal Resection in Three Dogs and One Cat
Authors: Siemon Heather
Published: July 2020

Based on splenic abnormalities noted during surgery, four client-owned animals (three dogs, one cat) undergoing exploratory laparotomy were identified as candidates for partial splenectomy. In three cases, small mass lesions of the spleen were identified on elective exploratory laparotomy. In one case, the patient was referred for emergency surgery for diaphragmatic hernia with entrapment of stomach and spleen. The discovery of avulsion of a significant portion of the splenic mesentery led to the decision to perform partial splenectomy in this case. All animals included in the study underwent partial splenectomy by one of two board-certified veterinary surgeons at a multispecialty hospital between 2014 and 2018. The same type of bipolar vessel-sealing device was used in each surgery, and three of four partial splenectomy cases recovered uneventfully. One patient went into cardiopulmonary arrest hours after surgery and died; however, this is not suspected to be due to the described partial splenectomy technique. The bipolar vessel-sealing device is suitable for use in resection of the splenic parenchyma in some canine and feline patients. This technique is designed to decrease surgical time, provide effective hemostasis, and preserve the important functions of the spleen that are lost when total splenectomy is undertaken.
Not as you R: Adapting the French rhotic into Berber
Authors: Lahrouchi Mohamed
Published: July 2020

This article examines the adaptation of the French rhotic in Berber. In loanwords borrowed from French, the uvular fricative is systematically interpreted as a coronal tap, despite the fact that Berber has phonemic /ʁ/ and /χ/. It is argued that this phenomenon is determined by phonological rather than phonetic factors. It is shown that Tashlhiyt Berber speakers, including monolinguals, are able to identify the French r as a sonorant, based on their native phonology, where many co-occurrence restrictions are analyzed in terms of sonority-sensitive dependency relations between the most sonorous segment and its neighboring segments.
PRECONCEITO LINGUÍSTICO EM COMENTÁRIOS DE MEMES
Authors: Gaspar Mayara Do Rocio Lima , Do Carmo Márcia Cristina
Published: July 2020

Este artigo analisa o preconceito linguístico em comentários de memes em uma página presente na rede social Facebook. Como fundamentação teórica, segue-se a Teoria da Variação e Mudança Linguística (LABOV, 2008 [1972]) e discute-se a noção de preconceito linguístico a partir de trabalhos de Bagno (2002; 2007; 2009a; 2009b; 2017), Calvet (2002), dentre outros, incluindo sua presença nos ciberespaços (BEZERRA; PIMENTEL, 2016; RADTKE, 2017; ROMANO; PEREIRA, 2017). Ressaltamos a importância das orientações dos Parâmetros Curriculares Nacionais (BRASIL, 1998; 2000) no que tange a essa temática para o ensino de língua portuguesa. Por meio da análise de 100 dados, evidenciamos o preconceito linguístico de forma mais evidente em 44 comentários, mesmo sendo a página voltada a professores e profissionais da área da educação. A partir desta pesquisa, explicitamos a relevância do conteúdo de variação e mudança linguística na formação inicial e continuada de professores de língua portuguesa, a fim de combater o preconceito linguístico, muitas vezes pautado em um ensino tradicional de gramática normativa.
A VISÃO DE PROFESSORES DE LÍNGUA INGLESA NO ENSINO FUNDAMENTAL I SOBRE SUA FORMAÇÃO INICIAL
Authors: Sawada Vilkevicius Bianca Danielle , Brawerman Albini Andressa
Published: July 2020

No cenário global atual, há uma grande expansão de escolas bilíngues e escolas regulares que assumem o inglês como disciplina nos primeiros anos, mas muitos de seus professores não tiveram o preparo para lidar com crianças na sua formação. Vários autores mencionam as especificidades desse público, tais como Brown (2001), que ressalta a diferença de atenção entre o aluno criança e o adulto, e Ur (2012), que enfatiza o aprendizado implícito do público infantil. A partir disso, este artigo tem como objetivo investigar a visão dos professores de inglês do Ensino Fundamental I sobre sua formação inicial e se, de acordo com eles, a sua graduação os preparou profissionalmente para o momento da prática. Os dados de análise desta pesquisa foram coletados por meio de um questionário respondido por 14 professores que possuem pelo menos um curso de graduação, seja em Letras ou Pedagogia. Os resultados sugerem que os cursos aceitos como formação de professores de inglês para crianças não preparam totalmente para a prática e necessitam de uma reformulação.

Bone Marrow Edema, Clinical Significance, and Treatment Options: A Review
Authors: Akhavan Sam , Martinkovich Stephen C. , Kasik Connor , DeMeo Patrick J.
Published: July 2020

Bone marrow edema (BME) is a descriptive term used to describe high-signal intensity changes detected on magnetic resonance fluid-sensitive sequences that could be attributed to a number of underlying pathologies. Regardless of the cause, physiologic remodeling of the subchondral bone can be limited because of ongoing joint forces, increased focalization of stress, and reduced healing capacity of the subchondral bone. BME is a known prognostic factor associated with pain, dysfunction, and progressive cartilage damage. This review summarizes the current known causes of BMEs, theories related to histopathological changes, and current treatment options including novel biologic surgical options.
The Whole Grade Acceleration Policy in the Kingdom of Saudi Arabia and the State of Massachusetts, USA—An Analytical Comparative Study
Authors: Alarfaj Abdulhamid , Al-Omair Reem Abdul Latif
Published: July 2020

The research aims, through a comparative analytical study, to unveil whether there is an actual whole-grade acceleration policy in the kingdom of Saudi Arabia (KSA) if compared with that applied at Massachusetts, USA. Adopting such a policy secures the right of the gifted student to grow academically in proportion with his peculiar potentials. The research adopts the comparative analytical method (qualitative) using two tools: document analysis and semi-structured interview. The sample of the study comprised two education supervisors in charge of acceleration system in the department of the gifted in KSA and school principals applying the system in the state of Massachusetts. The foremost result, which the study came up to, was that the Saudi educational system has a comprehensive written acceleration policy based on scientific frameworks, while Massachusetts doesn’t have a specific document for applying a comprehensive acceleration policy. The research concluded with some recommendations among which are: The comprehensive acceleration policy in KSA still needs to develop, especially in the following areas: Classes and study levels on which the acceleration system and guidance services are applied, and The need to review acceleration procedures as they are among the obstacles that hinder an active application of the policy at the present time.
Still Unrecognized State “Turkish Republic of Northern Cyprus” in the Context of the Cyprus Negotiations: Status of the TRNC’ Court Decisions
Authors: Dolunay Ayhan , Kasap Fevzi
Published: July 2020

The issue of the recognition of the TRNC brings specific constraints because of the influence of the Cyprus peace talks, which have been ongoing for 50 years. After the new era started in 2014, the TRNC authorities’ efforts to reach an agreement and their struggle to make the TRNC recognized have been obstructed by barriers placed by the southern Cyprus administration. Each of the sides in the peace talks approaches each other’s demands positively or negatively. One of the other important problems is whether the decisions given by the TRNC Courts would create an effect like the court decisions given by the courts of any recognized states or not. In order for the court decisions of the TRNC judiciary to have the necessary effects, the TRNC must become effectively an equal on the negotiation table and a directly recognized state. Turkey has enabled the TRNC judiciary decisions to have an effect in Turkey by signing protocols with the TRNC, but what is the status of related court decisions in other countries? In this framework, this study aims to analyse the court decisions in other unrecognized states via the document analysis method. According to the findings, the TRNC’s judiciary decisions can have an effect in other countries. Additionally, the TRNC is a recognized state at least in a limited (indirect) manner and has political equality, but this needs to be improved further via direct recognition.

„Computer Wizards“ und Haecksen. Geschlechtsspeziﬁsche Rollenzuschreibungen in der privaten und subkulturellen Computernutzung in den USA und der Bundesrepublik / “Computer Wizards” and “Haecksen”. Gender Role Assignments in Private and Subcultural Computer Usage in the USA and the Federal Republic of Germany
Authors: Erdogan Julia Gül
Published: July 2020

Hacken stellte seit seinen Anfängen eine männlich geprägte Domäne dar. Weibliche Hacker blieben Ausnahmeerscheinungen, ihre Rolle wurde zudem marginalisiert. Dieser Umstand blieb weder von Außenstehenden noch von Hackern selbst unbemerkt und auch Arbeiten zur Geschichte der Hacker verweisen auf die Unterrepräsentation von Frauen. Mögliche Ursachen hierfür sind jedoch nicht eingehend analysiert worden. Der Beitrag widmet sich vor diesem Hintergrund der Frage nach geschlechtsspezifischen Rollenzuschrei- bungen in der privaten und subkulturellen Computernutzung in den USA und der Bundesrepublik von den 1970er bis in die frühen 1990er Jahre. Gezeigt wird erstens, welches Bild der Computerisierung und welches Selbstbild die Hacker entwarfen. Daran anschließend werden zweitens Rollenzuschreibun- gen und Narrative des „männlichen Genies“ einerseits und der „sorgenden Frau“ andererseits innerhalb und außerhalb der Hackerkulturen bezüglich der Computernutzung untersucht. Drittens wird beleuchtet, wie Hacker mit diesem Problem der ungleichen Geschlechterverhältnisse umgingen und wie ihr Habitus trotz Versuchen der Inklusion und geteilter Überzeugungen Computernutzerinnen den Zugang zur Hackerkultur erschwerten. Zuletzt wird am Fallbeispiel der sogenannten „Haecksen“ dargelegt, wie computeraffine Akteurinnen sich als Teil der Hackerkultur zu etablieren versuchten. Durch die Untersuchung soll verdeutlicht werden, dass Frauen nicht nur eine stumme Minderheit dieser Computerkulturen darstellten und wie die frühe subkul- turelle Computernutzung zur Aushandlung von Geschlechterrollen genutzt wurde. Erst durch eine kritische Auseinandersetzung mit dem Habitus, den Strukturen und der Reproduktion von Rollenklischees innerhalb der Hackerszene, konnten Anspruch und Wirklichkeit der Hackerkultur gewinnbringend gegenübergestellt werden.
Deutsche Kurorte als Schaubühnen für die „English sports“ Tennis und Golf
Authors: Gillmeister Heiner
Published: July 2020

Against the backdrop of the introduction of “English sports” into 19th-century Germany, her famous spas played a significant role in making fashionable games such as lawn tennis and golf popular. These spas were the haunts of well-to-do English pensioners and tourists who became their first and almost exclusive patrons. Places like Bad Homburg were also the first to see first-class English players in action. The presence of these sportspeople, and of both English and German royalty at these spas added lustre to their sporting activities and soon attracted the attention of the German burgher. In addition the coverage these games received in high-class journals such as Sport im Bild, edited by the Rotterdam-born Scotsman Andrew Pitcairn-Knowles, and in the lawn tennis yearbooks by Robert Baron von Fichard of Baden-Baden, encouraged more people to adopt the sport of their social betters. The prestige of German spas radiated well beyond the 20th century. Only recently, their illustrious sporting history has been an asset in their applying for recognition as a UNESCO world cultural heritage site. Their golf clubs have been granted the right to add to their names the epithet “royal”, and one of them, Bad Homburg, will host a women’s tennis event in partnership with Wimbledon, immediately preceding The Championships, in the years to come. The present essay examines the historic part played by the German spas in the country’s sports scenario over the decades.
Berufseinstiegsverläufe: Berufliche Integration nach betrieblicher Berufsausbildung
Authors: Dorau Ralf
Published: July 2020

Ein entscheidender Übergang im Lebensverlauf ist die Passage von der Ausbildung in den Beruf. Allerdings ist dieser bei Absolvent*innen einer dualen Ausbildung nicht immer gelungen. Fast ein Viertel der Berufseinstiegsverläufe der im Jahr 2012 befragten Absolvent*innen der Abschlusskohorten 2006 bis 2008 ist prekär beschäftigt und knapp 5 % sind entkoppelt. Über Mehrebenenanalysen werden die Einflussfaktoren auf die berufliche Integration analysiert. Es zeigen sich größere Disparitäten zwischen Ost- und Westdeutschland sowie ein deutlicher Einfluss des Schulabschlusses und vor allem der Abschlussnote. Außerdem sind weibliche Fachkräfte häufiger prekär beschäftigt und seltener beruflich integriert als männliche Fachkräfte. Weiterhin finden sich in einzelnen Berufsfeldern Unterschiede hinsichtlich beruflicher Integration, und mit entsprechenden Kontexteffekten, wie beispielsweise bei weiblich dominierten Berufen, sinken die Chancen gelungener Integration.
Umkämpfte Mitbestimmung: Ergebnisse der dritten WSI-Befragung zur Be- und Verhinderung von Betriebsratswahlen
Authors: Behrens Martin , Dribbusch Heiner
Published: July 2020

Dieser Beitrag präsentiert die Ergebnisse der 3. WSI-Befragung zur Be- und Verhinderung von Betriebsratswahlen. Die Befragung wurde unter lokalen Gewerkschaftsorganisationen durchgeführt. Sie wurde 2019 abgeschlossen und schließt an zwei ähnliche Studien der Jahre 2012 und 2015 an. Die Befunde bestätigen, dass die Gründung eines Betriebsrats ein umstrittenes Unterfangen ist. Die Be- und Verhinderung der Wahl von Betriebsräten durch Arbeitgeber findet sich insbesondere bei inhabergeführten kleinen und mittleren Betrieben. Der Beitrag reflektiert zunächst das bestehende System der industriellen Arbeitsbeziehungen in Deutschland und stellt sodann die Erhebung und ihre Resultate vor. Abschließend wird diskutiert, welche Gründe ausschlaggebend dafür sein könnten, dass etwa die Hälfte der befragten Gewerkschaftseinheiten keinen Fall arbeitgeberseitiger Einmischung in Betriebsratswahlen berichtet, während die andere Hälfte zum Teil mehrere Aktivitäten zur Verhinderung von Betriebsratswahlen bzw. zur Behinderung der Betriebsratsarbeit zu Protokoll gibt.
Auswirkungen von "Button-Lösung" und Widerrufsrecht auf den Eingehungsbetrug
Authors: Dämmer Jakob
Published: July 2020

Die Situation, dass der durch "Button-Lösung" und Widerrufsrecht intendierte Verbraucherschutz bei Betrugsmaschen im Internet oft versagt und dazu eine Minderung des strafrechtlichen Schutzes befürchten lässt, scheint unbefriedigend. Der Autor verdeutlicht die Konsequenzen der "Button-Lösung" für den Eingehungsbetrug und zeigt einen Weg auf, der durch Präzisierung des Begriffs der Vermögensverfügung – anders als bisherige Lösungsansätze – ohne Widersprüche zu einer wirtschaftlichen Vermögensbewertung auskommt. Da auch das Widerrufsrecht bei Betrugsmaschen häufig kaum Schutz bietet, nimmt der Autor anhand einer wirtschaftlichen Vermögensbewertung die insoweit gebotene differenzierte Analyse der Auswirkungen auf den Eingehungsbetrug vor.
Missbrauchskontrolle im TK- und Energiesektor zwischen Regulierung und kommunalem Handeln
Authors: Karrer Till
Published: July 2020

Monopolanfälligkeit und das Ziel funktionsfähigen Wettbewerbs in den Netzsektoren erfordern insbesondere eine wirksame Kontrolle des Missbrauchs von Marktmacht – gerade auf Ebene der Netzinfrastruktur. Gleichzeitig werden immer umfassendere Ausbauanforderungen an die Netze gestellt und neben Unternehmen und dem Bund sind auch die Kommunen beim Breitbandausbau und der Energiekonzessionsvergabe relevante Akteure im Bereich der Netzinfrastruktur.

Auf diese Gemengelage aus Akteuren, Vorgaben, Systematiken und Interessen richtet die Arbeit einen umfassenden, vergleichenden und ordnenden Blick und zeigt Widersprüche sowie Verbesserungsbedarf auf – insbesondere mittels Einblicken aus der anwaltlichen Praxis in den beiden Sektoren.

« J’aimerais mourir. » Comprendre le désespoir chez les jeunes trans par le concept d’oppression développementale
Authors: Medico Denise , Pullen Sansfaçon Annie , Galantino Gabriel J. , Zufferey Adèle
Published: July 2020

La suicidalité chez les jeunes trans est très importante. La recherche montre qu’il y a de meilleures chances de la prévenir, dans un contexte social aidant, avec du soutien parental et un accès aux traitements de confirmation de genre. Or, que vivent les jeunes trans et leur famille dans des contextes où, comme c’est le cas de la Suisse francophone, les traitements sont peu accessibles, d’une part, et où, d’autre part, la transitude est pratiquement invisible? Dans le cadre d’une recherche participative inspirée par la théorie ancrée, dix jeunes et dix parents ont été interrogés pour documenter la situation. De fait, le suicide et « l’envie de mourir » sont très présents pour ces jeunes, qui considèrent l’inadaptation actuelle des structures de soin comme un enjeu majeur. Se révéler à soi-même et aux autres et être soutenu par les soignants sont de la plus grande importance pour sortir de l’envie de mourir. Cet article montre comment la notion d’oppression développementale peut aider à mieux comprendre la suicidalité chez les jeunes trans.
Altered expression of a quality control protease in E. coli reshapes the in vivo mutational landscape of a model enzyme
Authors: Thompson Samuel , Zhang Yang , Ingle Christine , Reynolds Kimberly A , Kortemme Tanja
Published: July 2020

Protein mutational landscapes are shaped by the cellular environment, but key factors and their quantitative effects are often unknown. Here we show that Lon, a quality control protease naturally absent in commonE. coliexpression strains, drastically reshapes the mutational landscape of the metabolic enzyme dihydrofolate reductase (DHFR). Selection under conditions that resolve highly active mutants reveals that 23.3% of all single point mutations in DHFR are advantageous in the absence of Lon, but advantageous mutations are largely suppressed when Lon is reintroduced. Protein stability measurements demonstrate extensive activity-stability tradeoffs for the advantageous mutants and provide a mechanistic explanation for Lon’s widespread impact. Our findings suggest possibilities for tuning mutational landscapes by modulating the cellular environment, with implications for protein design and combatting antibiotic resistance.
Combining agent-based, trait-based and demographic approaches to model coral-community dynamics
Authors: Carturan Bruno Sylvain , Pither Jason , Maréchal Jean-Philippe , Bradshaw Corey JA , Parrott Lael
Published: July 2020

The complexity of coral-reef ecosystems makes it challenging to predict their dynamics and resilience under future disturbance regimes. Models for coral-reef dynamics do not adequately account for the high functional diversity exhibited by corals. Models that are ecologically and mechanistically detailed are therefore required to simulate the ecological processes driving coral reef dynamics. Here, we describe a novel model that includes processes at different spatial scales, and the contribution of species’ functional diversity to benthic-community dynamics. We calibrated and validated the model to reproduce observed dynamics using empirical data from Caribbean reefs. The model exhibits realistic community dynamics, and individual population dynamics are ecologically plausible. A global sensitivity analysis revealed that the number of larvae produced locally, and interaction-induced reductions in growth rate are the parameters with the largest influence on community dynamics. The model provides a platform for virtual experiments to explore diversity-functioning relationships in coral reefs.
Smartphone Brand Loyalty and Consumer Heterogeneity
Authors: Susilowati Etty , Ardhita Putra Mohammad Guntur
Published: July 2020

Research Question: The purpose of this study is to examine the effect of sales promotion and advertisement on brand association and brand loyalty of Samsung smartphones via the analysis of gender and age as moderating variables. Motivation: The motivation for this study emerges from the fact that the effect of sales promotion and advertisement on brand loyalty have not considered the effects of consumer heterogeneity such as age and gender. Idea: The core idea of this study is to verify the effect of monetary promotion, non-monetary promotion, perceived advertising, and individual attitude towards brand association and brand loyalty through the moderate effects of age and gender. Data: This research was carried out in South Jakarta, Indonesia by employing a simple random sampling method and questionnaires distributed to 100 respondents. Tools: Data were analyzed by using Partial Least Square Structural Equation (PLS-SEM) method and the SmartPLS 3.0 software. The PLS-SEM was performed with a two-step approach by analyzing the outer and inner model, afterwards followed by a multi-group analysis to analyze moderating effects of both variables of gender and age. Findings: The findings indicate that non-monetary promotion and individual attitude towards advertising significantly affect brand association while brand association significantly affects brand loyalty. Gender and age-specific analyses indicate that gender differences significantly moderate the influence of individual attitude towards advertising on brand association and age differences significantly moderate the effect of monetary promotion on brand association. Moreover, women, men, younger and older consumers behave differently towards sales promotion. Contribution: This study contributes to the literature by adding empirical evidences in terms of how different consumers respond to sales promotion and advertising as well as further effects on brand association and brand loyalty.
Percepciones de los estudiantes de la especialidad de lengua extranjera - inglés sobre atención a la diversidad en la formación inicial del profesorado de Educación Secundaria
Authors:   Universidad de Granada (España), Crisol Moya Emilio , Caurcel Cara M.ª Jesús ,   Universidad de Granada (España)
Published: July 2020

Diseñar e implementar prácticas inclusivas se considera como una de las líneas de actuación básicas para la construcción de una educación inclusiva; acciones que dependen en gran parte de las actitudes del profesorado, pudiendo estas verse modificadas por la formación que reciben. En este marco, esta investigación analizó las percepciones de 76 estudiantes de la especialidad de lengua extranjera - inglés acerca de la formación inicial recibida sobre la atención a la diversidad en el Máster Universitario en Profesorado de Educación Secundaria Obligatoria, Formación Profesional y Enseñanza de Idiomas (MAES) en la Universidad de Granada (UGR) (España), durante el curso académico 2018/2019. Se trata de un estudio descriptivo, correlacional de tipo transversal de las respuestas obtenidas a través del “Cuestionario para futuros docentes de Educación Secundaria acerca de las percepciones sobre atención a la diversidad” (Colmenero Ruiz y Pegalajar Palomino, 2015). De los resultados obtenidos se deduce que, en general, el profesorado en formación posee actitudes favorables hacia la diversidad y el principio de inclusión. Asimismo, se aprecia que los estudiantes de género femenino poseen actitudes ligeramente más positivas que los de género masculino, existiendo también diferencias estadísticamente significativas en la consideración de la diversidad entre aquellos que han tenido contacto con personas con discapacidad o trastornos. Se concluye que resulta apropiado continuar incidiendo sobre el plano actitudinal, en relación a esta temática, en tales titulaciones.
El graffiti como motor del pensamiento crítico en lengua extranjera
Authors:   Universidad de Granada (España), Aguilera Carnerero Carmen
Published: July 2020

Este artículo plantea una propuesta educativa que reivindica la inclusión del graffiti1 como objeto de estudio de una asignatura de español para extranjeros. Además de su infravalorado potencial desde una perspectiva meramente lingüística (como texto escrito), el graffiti puede resultar, sobre todo, una magnífica herramienta pedagógica que promueva el pensamiento crítico y la formación de ciudadanos intelectualmente activos. La incorporación del graffiti al currículo académico se justifica por la existencia de un marco educativo que prima la transversalidad como eje central para superar la mera concepción de la enseñanza como transmisión de conocimientos, así como alienta el desarrollo de alumnos capaces de aplicar los mismos para adquirir un compromiso social.
ESP1 within ESP: the design and implementation of a pronunciation module in a technical English course
Authors:   Universidad Rovira i Virgili (España), Quesada Vázquez Leticia , Romero Joaquín ,   Universidad Rovira i Virgili (España)
Published: July 2020

This paper focuses on the design and implementation of a ten-week pronunciation module within a university technical English course as part of a broader study that investigates the efficacy of explicit rhythm instruction to improve engineering students’ prosody in English. Sessions were adapted to the course contents and followed Celce-Murcia, Brinton & Goodwin's (1996) steps to teach communicatively. The participants were 298 Spanish/Catalan-speaking first-year undergraduate engineering students divided into three experimental groups and three control groups. The experimental groups received explicit rhythm instruction while the control groups did not. They all were recorded before and after the training. Ten sentences were analyzed acoustically and measures of rhythm (VarcoV) were obtained. Preliminary results revealed that students who took rhythm instruction tended to increase their VarcoV values, approaching English rhythm, while the control group showed a volatile behavior. The comparison of the effect sizes of each group’s differences in performance before and after instruction was statistically significant. Findings suggest that rhythm instruction can be beneficial to enhance EFL students’ prosody and that pronunciation can be effectively introduced within an ESP course.

Herein, the molecular dynamics (MD) simulations of pure Ni crystallites are performed to show the influence of the grain boundary (GB) geometry on the values of the activation energy of GB migration. The considered systems are bicrystal with Σ5[010] tilt plane boundary, spherical grain with initial curvature radius 5 nm, and polycrystalline 30 nm × 30 nm × 30 nm block. The motion of three types of GBs (flat, spherical, and polycrystalline) at constant temperatures and no applied forces is studied. The obtained values of activation energy are 0.45, 0.11, and 0.57 eV for flat, spherical, and polycrystalline types of GBs, respectively. These values are smaller than those that are reported in experimental works, which is a common issue for atomistic simulations of GB migration. Possible sources of such disagreement and ways to overcome it are discussed. The particular part of this work is devoted to the development of the automated analysis of polycrystalline structure. This analysis provides detailed information on grain size distribution and its evolution in time.

The hot deformation characteristics of a novel nickel‐based superalloy is investigated via the isothermal compression test in temperature range of 1000–1150 °C and strain rate of 0.001–10 s−1 under the true strain of 0.8. The hot deformation characteristics of GH4065 alloy are studied here for the first time. Based on the flow stress data, it is observed the typical features of flow curves exhibit the occurrence of dynamic recrystallization (DRX) during the hot deformation process. The constitutive equation in the Arrhenius‐type model is established, and activation energy (Q) is determined as 844.787 kJ mol−1. The microstructure evolution and DRX mechanism are investigated by electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) technique. The results reveal that the fraction of low angle grain boundaries (LAGBs) decrease gradually with the increase in deformation temperature, whereas the fraction of Σ3 boundaries increase first and then decrease. For γ + γ′ dual‐phase region, the particle‐induced DRX (PIDRX), characterized by the generation of sub‐grains accelerated by γ′ precipitates pinning dislocations, and discontinuous dynamic recrystallization (DDRX) are the dominant nucleation mechanism of DRX. For γ quasi‐phase region and γ single‐phase region, the occurrence of bulged grain boundaries with twins further illustrates that DDRX plays a more significant role.
Acoustic Gain in Solids due to Piezoelectricity, Flexoelectricity, and Electrostriction

Published: July 2020

A quantitative discussion of the combined influence of three electromechanical effects: piezoelectricity, flexoelectricity, and electrostriction in solids is provided for acoustic absorption and gain. While piezoelectricity occurs in non‐centrosymmetric materials only, flexoelectricity and electrostriction exist in all materials. Two important new results are demonstrated: 1) the possibility to realize acoustic gain in all materials (centrosymmetric and non‐centrosymmetric) when the acoustic Cherenkov condition is fulfilled, and 2) realization of acoustic gain in the presence of a strong dc electric field, even when the Cherenkov condition is not fulfilled, in the case of strong cross‐coupling between piezoelectricity, flexoelectricity, and electrostriction. A simple analytical expression for the acoustic dispersion relation is derived for the combined effect of piezoelectricity, flexoelectricity, and electrostriction. At lower frequencies, the piezoelectric effect dominates for inversion‐asymmetric materials. At high frequencies (≈>1 MHz) flexoelectricity becomes increasingly important and eventually provides a major mechanism for gain and absorption in barium titanate (BaTiO3). In the presence of strong electric fields (≈>1 MV m−1), electrostriction provides a dominant isolated contribution to absorption/gain in BaTiO3. Strong coupling between the three electromechanical contributions determines the total absorption/gain coefficient.

The development of earth‐abundant and efficient oxygen evolution reaction (OER) electrocatalysts is necessary for green hydrogen production. The preparation of efficient OER electrocatalysts requires both the adsorption sites and charge transfer on the catalyst surface to be suitably engineered. Herein, the design of an electrocatalyst is reported with significantly enhanced water oxidation performance via dual‐phase engineering, which displays a high number of adsorption sites and facile charge transfer. More importantly, a simple chemical etching process enables the formation of a highly metallic transition boride phase in conjunction with the transition metal hydroxide phase with abundant adsorption sites available for the intermediates formed in the OER. In addition, computational simulations are carried out to demonstrate the water oxidation mechanism and the real active sites in this engineered material. This research provides a new material design strategy for the preparation of high‐performance OER electrocatalysts.

Published: July 2020

C1 chemistry, which is the catalytic transformation of C1 molecules including CO, CO2, CH4, CH3OH, and HCOOH, plays an important role in providing energy and chemical supplies while meeting environmental requirements. Zeolites are highly efficient solid catalysts used in the chemical industry. The design and development of zeolite‐based mono‐, bi‐, and multifunctional catalysts has led to a booming application of zeolite‐based catalysts to C1 chemistry. Combining the advantages of zeolites and metallic catalytic species has promoted the catalytic production of various hydrocarbons (e.g., methane, light olefins, aromatics, and liquid fuels) and oxygenates (e.g., methanol, dimethyl ether, formic acid, and higher alcohols) from C1 molecules. The key zeolite descriptors that influence catalytic performance, such as framework topologies, nanoconfinement effects, Brønsted acidities, secondary‐pore systems, particle sizes, extraframework cations and atoms, hydrophobicity and hydrophilicity, and proximity between acid and metallic sites are discussed to provide a deep understanding of the significance of zeolites to C1 chemistry. An outlook regarding challenges and opportunities for the conversion of C1 resources using zeolite‐based catalysts to meet emerging energy and environmental demands is also presented.

Published: July 2020

Stimulator of interferon genes (STING) activation by intratumoral STING agonist treatment has been recently shown to eradicate tumors in preclinical models of cancer immunotherapy, generating intense research interest and leading to multiple clinical trials. However, there are many challenges associated with STING agonist‐based cancer immunotherapy, including low cellular uptake of STING agonists. Here, biodegradable mesoporous silica nanoparticles (bMSN) with an average size of 80 nm are developed for efficient cellular delivery of STING agonists. STING agonists delivered via bMSN potently activate innate and adaptive immune cells, leading to strong antitumor efficacy and prolonged animal survival in murine models of melanoma. Delivery of immunotherapeutic agents via biodegradable bMSN is a promising approach for improving cancer immunotherapy.

Grains and grain boundaries play key roles in determining halide perovskite‐based optoelectronic device performance. Halide perovskite monocrystalline solids with large grains, smaller grain boundaries, and uniform surface morphology improve charge transfer and collection, suppress recombination loss, and thus are highly favorable for developing efficient solar cells. To date, strategies of synthesizing high‐quality thin monocrystals (TMCs) for solar cell applications are still limited. Here, by combining the antisolvent vapor‐assisted crystallization and space‐confinement strategies, high‐quality millimeter sized TMCs of methylammonium lead iodide (MAPbI3) perovskites with controlled thickness from tens of nanometers to several micrometers have been fabricated. The solar cells based on these MAPbI3 TMCs show power conversion efficiency (PCE) of 20.1% which is significantly improved compared to their polycrystalline counterparts (PCE) of 17.3%. The MAPbI3 TMCs show large grain size, uniform surface morphology, high hole mobility (up to 142 cm2 V−1 s−1), as well as low trap (defect) densities. These properties suggest that TMCs can effectively suppress the radiative and nonradiative recombination loss, thus provide a promising way for maximizing the efficiency of perovskite solar cells.
