Authors: Marco Jiménez Francisco , Peñaranda David , Naturil Alfonso Carmen , Vicente José 
Published: July 2018

Las competencias y habilidades a adquirir por parte del estudiante han evolucionado, por lo que la metodología educativa también debe evolucionar. La sociedad demanda profesionales con competencias y habilidades en tecnologías de la información y la comunicación (TIC) y que demuestren un pensamiento crítico y deductivo. El objetivo del presente trabajo es la descripción de un proyecto docente que propone la implantación de la clase inversa en combinación con TIC y metodologías estimuladoras del aprendizaje, como la gamificación. El proyecto docente se aplicará en la asignatura de Fisiología Animal y Humana (Grado en Biotecnología; Universitat Piltècnica de València), tanto en el grupo Alto Rendimiento Académico (lengua vehicular inglés) como en un segundo grupo donde la lengua vehicular es el castellano.Han sido propuestas 5 actividades diseñadas para alcanzar las competencias transversales propuestas en la asignatura. El docente, basado en los indicadores de consecución y las evidencias de competencia, evaluará la efectividad del proyecto, comparando el grado de adquisición de las competencias previo o post-implantación del proyecto. Además, también se comparará la calificación final respecto a años anteriores, testando así si la innovadora estrategia educativa ha tenido un impacto en la nota final de la asignatura.Palabras clave: clase invertida, TIC, gamificación, proyecto docente.
Mala gestión del tiempo en los estudiantes universitarios: efectos de la procrastinación
Authors: Marco Jiménez Francisco , Naturil Alfonso Carmen , Peñaranda David , Vicente José 
Published: July 2018

La procrastinación académica es un término que hace referencia a la postergación o posposición de cualquier actividad o tarea académica para el último minuto. Este fenómeno prevalece de forma mayoritaria entre los estudiantes universitarios, y su incidencia parece ir en aumento. Con el fin de analizar las posibles causas y/soluciones a la procrastinación, en este trabajo se estudió si un mayor tiempo para la elaboración y/o desarrollo de las actividades y tareas universitarias impedía o incentivaba la procrastinación entre los estudiantes universitarios. Los resultados mostraron que tanto los grupos con menor tiempo para el desarrollo de tareas, como los grupos con un mayor tiempo tendían a procrastinar de la misma manera. Además, las notas medias de las tareas no mostraron diferencias entre los grupos dado que la procrastinación fue la misma en ambos grupos. Por ello, este estudio muestra que incluso con periodos más prolongados para la elaboración de la actividad, los estudiantes universitarios tienden a procrastinar, y este hecho parece tener un efecto negativo sobre la nota de la actividad. En conclusión, la procrastinación es un grave problema en el sistema universitario actual y deberían tomarse medidas para solucionarlo.Palabras clave: Procrastinación; gestión del tiempo; trabajo académico; resultados académicos
Impact of gravity waves on the motion and distribution of atmospheric ice particles
Authors: Podglajen Aurélien , Plougonven Riwal , Hertzog Albert , Jensen Eric 
Published: July 2018

Abstract. Gravity waves are an ubiquitous feature of the atmosphere and influence
clouds in multiple ways. Regarding cirrus clouds, many studies have
emphasized the impact of wave-induced temperature fluctuations on the
nucleation of ice crystals. This paper investigates the impact of the waves
on the motion and distribution of ice particles, using the idealized 2-D
framework of a monochromatic gravity wave. Contrary to previous studies,
special attention is given to the impact of the wind field induced by the wave. Assuming no feedback of the ice on the water vapor content, theoretical and
numerical analyses both show the existence of a wave-driven localization of ice crystals, where some ice particles remain confined in a
specific phase of the wave. The precise location where the confinement occurs
depends on the background relative humidity, but it is always characterized
by a relative humidity near saturation and a positive vertical wind anomaly. Hence, the wave has an impact on the mean motion of the crystals
and may reduce dehydration in cirrus by slowing down the sedimentation of the
ice particles. The results also provide a new insight into the relation
between relative humidity and ice crystals' presence. The wave-driven localization is consistent with temperature–cirrus
relationships recently observed in the tropical tropopause layer (TTL) over
the Pacific during the Airborne Tropical Tropopause EXperiment (ATTREX). It
is argued that this effect may explain such observations. Finally, the impact
of the described interaction on TTL cirrus dehydration efficiency is
quantified using ATTREX observations of clouds and temperature lapse rate.
The Power of the Archive in El negro Francisco by Antonio Zambrana
Authors: Camacho Jorge 
Published: July 2018

During most of the 19th century, an important body of literary works appeared outside of Cuba criticizing the institution of slavery on the island, the system’s inherent violence, its sexual practices, and its repercussions on the white population. Among the most famous works published at the time were Sab (1841), by Gertrudis Gómez de Avellaneda, and Cecilia Valdés ([1839] 1882), by Cirilo Villaverde. In this essay, I would like to explore a lesser known novel that was published by a Cuban writer of the following generation—El negro Francisco (1875), by Antonio Zambrana y Vazquez—in order to understand the principal role of the legal and anthropological archives in the novel, as well as the author’s use of newspaper reports and advertisements. How are these texts and styles intertwined in the novel to criticize institutional slavery on the Island? How does the authorial voice appear in the novel when we consider a tradition present since the beginning of the Spanish Conquest of the Americas—which reached the 20th century with novels such as Los pasos perdidos (1958) by Alejo Carpentier? I would base my arguments on Roberto González Echevarría’s interpretation of Latin American novel in Mito y Archivo, una teoría de la narrativa latinoamericana, in which he employs basic concepts of US critical anthropology in order to re-interpret various aspects of 19th century Latin American history.
Pushing the Line: Teaching Suburban Seventh Graders to be Critically Conscious through Historical Inquiry and Civic Letter-Writing
Authors: Beutel Andy 
Published: July 2018

Engaging in critical teaching with non-marginalized suburban middle school students is both challenging and necessary in the Age of Trumpism. In this paper, I explain the constraints on critical educators teaching in an affluent, suburban public school setting as well as the possibilities for working within this system to increase students’ critical consciousness. In the inquiry-based learning project I describe, I combine critical pedagogy theory with historical literacy pedagogy in order to enable seventh grade students in a world history course to critique current problems in the United States under Trump through the comparative analysis of different historical and modern sources and action-based letter-writing to the president. I include an overview an explanation of the school setting and culture, a rationale for and summary of the lessons within the inquiry project, a description of the class discussions, and excerpts from students’ letters and reflections revealing their thinking.
After #Charlottesville: Interrogating our Racist Past in the Trump Era
Authors: Boyce Travis 
Published: July 2018

In wake of the violent and deadly events in Charlottesville and President Donald Trump’s response in which he effectively defended the Neo-Nazis and Confederate monuments, it’s important that college students understand the Lost Cause movement, the building of Confederate monuments and how college campuses are affected. In preparation for the fall 2017 semester, I revised my AFS 310 African Americans and U.S. Education syllabus in which I devoted the first five weeks of the semester to interrogating the aftermath of Charlottesville and this nation’s Confederate legacies on college campuses. Centering the unit’s theme on “The Lost Cause and the Collegiate Idea,” this article will discuss in depth the unit I taught as well as student assessment and outcomes upon completion of the unit.
Radical Digital Media Literacy in a Post-Truth Anti-Trump Era
Authors: Juhasz Alexandra 
Published: July 2018

I have engaged in a series of linked pedagogical experiments—one woman’s pedagogic resistance, aligned with many others through making poetry together, by way of digital media literacy—over the duration of the Trump administration. These have been acts of engaged, enraged intellectual citizenship in three parts: 1. an online digital media primer about fakenews, #100hardtruths-#fakenews, produced over the first 100 days of the administration; 2. nine Fake News Poetry Workshops held over the spring semester of 2018, these making use of that online primer and co-facilitated by poets in different locations and communities, and 3. an action plan to further mobilize the primer, poems, and workshops to a scale larger than my own personal pedagogy, still in process. These experiments are first and foremost acts of civic engagement qua pedagogy, art-making, and community-building. They are organized to create and make use of responsive formats, processes, and places to better express our keen knowledge, concern, and curiosity about inter-related phenomena given the current crisis of fake news: self, community, and the world, the fake and real, our own power and that of (social) media.

L’acquisition de la phonologie en français langue seconde : le profil phonologique d’enfants allophones en maternelle
Authors: Meziane Rabia Sabah , MacLeod Andrea A. N. 
Published: July 2018

La ville de Montréal est l’une des villes les plus multiethniques du Canada. Compte tenu de cette diversité, il y a une grande proportion d’enfants qui apprennent deux langues et donc deux phonologies ; la phonologie de leur langue maternelle et celle du français. L’interaction entre ces deux systèmes phonologiques peut influencer le développement de la phonologie de la langue seconde. Le but de cet article est de comparer les compétences phonologiques en français des enfants allophones à celles des enfants francophones unilingues issues d’études précédentes. Nous utiliserons des mesures pour évaluer le pourcentage de consonnes bien produites par les enfants dans une tâche de dénomination d’images et nous analyserons différents facteurs qui peuvent contribuer aux résultats à cette tâche.

Published: July 2018

Introduction
In this study, a survey was prepared for urologists that asked about their primary choice of treatment for urolithiasis in daily practice and their answers were evaluated.

Methods
The survey was prepared on the Google Docs website and it was sent to 1,016 urologists via email with 752 confirmed deliveries. In addition to the demographic questions about each participant’s age, gender, and institution, the survey presented case scenarios focusing on their preferred treatment modalities for distal ureteric, proximal ureteric, and renal calculi. The participating urologists were divided into two groups according to the frequency that they treat urolithiasis patients.

Results
Of the 752 surveys delivered, 211 urologists (28.05%) responded and 204 answered all questions. According to the results, there were no significant differences between the treatment approaches and the other localizations, but there was a statistically significant difference for treatment approaches to lower pole stones between two groups. In response to the question of which stone treatment method was used less frequently, 124 (60.7%) participants answered that they used shock wave lithotripsy less in the last 10 years.

Conclusion
The present study has shown that while the management of renal and ureteric calculi by Turkish urologists is highly varied, the overall treatment patterns are in accordance with the European Association of Urology guidelines. However, similar to the global trend extracorporeal shock wave lithotripsy is less preferred by Turkish urologists.
Local Structural Heterogeneity and Electromechanical Responses of Ferroelectrics: Learning from Relaxor Ferroelectrics
Authors: Li Fei , Zhang Shujun , Damjanovic Dragan , Chen Long‐Qing , Shrout Thomas R. 
Published: July 2018

AbstractLong‐range ordering of dipoles is a key microscopic signature of ferroelectrics. These ordered dipoles form ferroelectric domains, which can be reoriented by electric fields. Relaxor ferroelectrics are a type of ferroelectric where the long‐range ordering of dipoles is disrupted by cation disorder, exhibiting complex polar states with a significant amount of local structural heterogeneity at the nanoscale. They are the materials of choice for numerous devices such as capacitors, nonlinear optical devices, and piezoelectric transducers, owing to their extraordinary dielectric, electro‐optic, and electromechanical properties. However, despite their extensive applications in these devices, the origins of their unique properties are yet to be fully understood, hindering the design and exploration of new relaxor ferroelectric‐based materials. Herein, the complex polar states and applications of relaxor ferroelectrics are first introduced. Attention is then focused on their electromechanical properties, where the relationship between local structural heterogeneity and the extraordinary electromechanical properties is discussed. Based on the understanding of relaxor ferroelectrics, potential strategies to exploit the local structural heterogeneity to design ferroelectrics for drastically enhancing their electromechanical performances are also discussed. It is expected that this article will stimulate future studies on the important roles of local structural heterogeneity in improving the properties of various functional materials.
Polydopamine‐Graphene Oxide Flame Retardant Nanocoatings Applied via an Aqueous Liquid Crystalline Scaffold

Published: July 2018

AbstractA highly effective flame retardant (FR) nanocoating was developed by conducting oxidative polymerization of dopamine monomer within an aqueous liquid crystalline (LC) graphene oxide (GO) scaffold coating. Due to its high water content, the LC scaffold coating approach facilitated fast transport and polymerization of dopamine precursors into polydopamine (PDA) within the water swollen interlayer galleries. Uniform and periodically stacked (14.5 Å d‐spacing) PDA/GO nanocoatings could be universally applied on different surfaces, including macroporous flexible polyurethane (PU) foam and flat substrates such as silicon wafers. Remarkably, PDA/GO coated PU foam exhibited highly efficient flame retardant performance reflected by a 65% reduction in peak heat release rate at 5 wt% PDA/GO loading in an 80 nm thick coating. While many physically mixed flame retardants are usually detrimental to the mechanical properties of the foam, the PDA/GO coating did not affect mechanical properties substantially. In addition, the PDA/GO coatings were stable in water due to the intrinsic adhesion capability of PDA and the transformation of GO to the more hydrophobic reduced GO form. Given that PDA is produced from dopamine, a molecule prevalent in nature, these findings suggest that significant opportunities exist for new polymeric FRs derived from other natural catechols.

AbstractMagnetic hyperthermia (MHT) and photothermal therapy (PTT) are emergent state‐of‐the‐art modalities for thermal treatment of cancer. While their mechanisms of action have distinct physical bases, both approaches rely on nanoparticle‐mediated remote onset of thermotherapy. Yet, are the two heating techniques interchangeable? Here, the heating obtained either with MHT or with PTT is compared. The heating is assessed in distinct environments and involves a set of nanomaterials differing in shape (spheres, cubes, stars, shells, and rods) as well as in composition (maghemite, magnetite, cobalt ferrite, and gold). The nanoparticle's heating efficacy in an aqueous medium is first evaluated. Subsequently, the heating efficiency within the cellular environment, where intracellular processing markedly decreases MHT, is compared. Conversely, endosomal sequestration could have a positive effect on PTT. Finally, iron oxide nanocubes and gold nanostars are compared in MHT and PTT in vivo within the heterogeneous intratumoral environment. Overall, two distinct therapeutic approaches, related to high dosage allowing MHT and low dosage associated with PTT, are identified. It is also demonstrated that PTT mediated by magnetic nanoparticles has an efficacy that is comparable to that of plasmonic nanoparticles, but only at significant nanoparticle dosages. At low concentrations, only plasmonic nanoparticles can deliver a therapeutic heating.

Published: July 2018

AbstractLithium metal is an ultimate anode in “next‐generation” rechargeable batteries, such as Li–sulfur batteries and Li–air (Li–O2) batteries. However, uncontrollable dendritic Li growth and water attack have prevented its practical applications, especially for open‐system Li–O2 batteries. Here, it is reported that the issues can be addressed via the facile process of immersing the Li metal in organic GeCl4–THF steam for several minutes before battery assembly. This creates a 1.5 µm thick protection layer composed of Ge, GeOx, Li2CO3, LiOH, LiCl, and Li2O on Li surface that allows stable cycling of Li electrodes both in Li‐symmetrical cells and Li–O2 cells, especially in “moist” electrolytes (with 1000–10 000 ppm H2O) and humid O2 atmosphere (relative humidity (RH) of 45%). This work illustrates a simple and effective way for the unfettered development of Li‐metal‐based batteries.
