The Place of Storytelling Research in English Language Teaching: The State of the Art

Storytelling techniques serve as dynamic tools for enhancing language skills, encompassing both receptive (listening, reading) and productive (speaking, writing) proficiencies. In contrast to their non-narrative counterparts, these techniques offer a more potent array of teaching methodologies. This study aims to elucidate the current landscape of research concerning the efficacy of storytelling techniques. Initially, the investigation delves into the cognitive processing of narratives. Stories engage language processing centers, invigorate the visual cortex, evoke emotive responses, and facilitate comprehension of intricate information. Subsequently, the study explores linguistic processing theory and embodied cognition theory. Through an exhaustive literature review, this research applies a rigorous evidence synthesis method to assess selected studies, culminating in the amalgamation of findings when comparability permits. The study unveils that storytelling techniques foster reading and listening comprehension, bolster speaking and writing skills, and kindle creativity and imagination. Moreover, enhancements span vocabulary, grammar, and syntax. Nonetheless, while generally efficacious, the uniformity of effectiveness across diverse learners remains a nuanced aspect

Students’ perception on TPACK practices on online language classes in the midst of pandemic

This study investigated technological pedagogical and content knowledge (TPACK) practices during the current COVID-19 pandemic and examined factors influencing students’ perceptions of effective online learning. This study gathered the primary data from 90 university students from four study programs via the online questionnaire. Using an analysis of variance (ANOVA) statistical tool for data analysis, this study found that students’ perceptions of their teachers’ teaching performance in the fully online programs are not significantly different across four study programs. This finding implies that regardless of their study programs, the students had expected that teachers should pay attention to some vital aspects in online learning: using the same learning management system (LMS) for all study programs, and preparing designing practical online modules, taking care of the organization of teaching inputs that promote students’ critical thinking, delivering various teaching inputs and methods, intensifying teachers’ presence in monitoring students’ learning progress, motivating students to learn, and promoting teacher-student mutual respect through effective communication. This study also revealed that teachers play a pivotal role in achieving effective online learning during the pandemic

Impact of bimetallic interface design on heat generation in plasmonic Au/Pd nanostructures studied by single-particle thermometry

Localized surface plasmons are lossy and generate heat. However, accurate measurement of the temperature of metallic nanoparticles under illumination remains an open challenge, creating difficulties in the interpretation of results across plasmonic applications. Particularly, there is a quest for understanding the role of temperature in plasmon-assisted catalysis. Bimetallic nanoparticles combining plasmonic with catalytic metals are raising increasing interest in artificial photosynthesis and the production of solar fuels. Here, we perform single-particle thermometry measurements to investigate the link between morphology and light-to-heat conversion of colloidal Au/Pd nanoparticles with two different configurations: core–shell and core-satellite. It is observed that the inclusion of Pd as a shell strongly reduces the photothermal response in comparison to the bare cores, while the inclusion of Pd as satellites keeps photothermal properties almost unaffected. These results contribute to a better understanding of energy conversion processes in plasmon-assisted catalysis.Fil: Gargiulo, Julian. Consejo Nacional de Investigaciones Científicas y Técnicas.

In situ photothermal response of single gold nanoparticles through hyperspectral imaging anti-stokes thermometry

Several fields of applications require a reliable characterization of the photothermal response and heat dissipation of nanoscopic systems, which remains a challenging task for both modeling and experimental measurements. Here, we present an implementation of anti-Stokes thermometry that enables the in situ photothermal characterization of individual nanoparticles (NPs) from a single hyperspectral photoluminescence confocal image. The method is label-free, potentially applicable to any NP with detectable anti-Stokes emission, and does not require any prior information about the NP itself or the surrounding media. With it, we first studied the photothermal response of spherical gold NPs of different sizes on glass substrates, immersed in water, and found that heat dissipation is mainly dominated by the water for NPs larger than 50 nm. Then, the role of the substrate was studied by comparing the photothermal response of 80 nm gold NPs on glass with sapphire and graphene, two materials with high thermal conductivity. For a given irradiance level, the NPs reach temperatures 18% lower on sapphire and 24% higher on graphene than on bare glass. The fact that the presence of a highly conductive material such as graphene leads to a poorer thermal dissipation demonstrates that interfacial thermal resistances play a very significant role in nanoscopic systems and emphasize the need for in situ experimental thermometry techniques. The developed method will allow addressing several open questions about the role of temperature in plasmon-assisted applications, especially ones where NPs of arbitrary shapes are present in complex matrixes and environments.Fil: Barella, Mariano.

Challenges on Optical Printing of Colloidal Nanoparticles

While colloidal chemistry provides ways to obtain a great variety of nanoparticles with different shapes, sizes, material composition, and surface functions, their controlled deposition and combination on arbitrary positions of substrates remains a considerable challenge. Over the last ten years, optical printing arose as a versatile method to achieve this purpose for different kinds of nanoparticles. In this article, we review the state of the art of optical printing of single nanoparticles and discuss its strengths, limitations, and future perspectives, by focusing on four main challenges: printing accuracy, resolution, selectivity, and nanoparticles photostability.Fil: Violi, Ianina Lucila.

MINUTO CORONA: A EXTENSÃO UNIVERSITÁRIA NO ENFRENTAMENTO DA PANDEMIA DE COVID-19

Em março de 2020, a Coronavírus Disease (COVID-19), até então desconhecida e sem tratamento específico, preocupou o mundo, principalmente pela transmissibilidade. A população, em sua grande parte mais leiga, assistia a tudo isso sem saber muito bem o que fazer ou como reagir, e surgiam, a todo momento, orientações que se fizeram necessárias para (con)vivermos como sociedade diante de inúmeros questionamentos. Entendemos que se fazia necessário construir um diálogo com a população em geral, visando a dispor de uma comunicação efetiva sobre o cenário da pandemia. Percebemos que a carência de informação qualificada, as dúvidas e as fake news seriam um obstáculo para as pessoas entenderem a gravidade da situação desencadeada pelo coronavírus. Desta forma, como voluntários, nos unimos em uma Ação de Extensão denominada MINUTO CORONA, que tem como pilar a construção do conhecimento além dos muros da universidade, com o foco na comunicação rápida e eficaz. Nosso objetivo é responder as perguntas e publicar conteúdos científicos. Estes são divididos em categorias, como: máscaras, testes e diagnósticos, sinais e sintomas, contágio, desinfecção e limpeza, medicações, vacinas, fake news, orientações e relatos. Nosso diferencial: responder e interagir com as pessoas. As evidências científicas foram a mola propulsora da equipe, a partir das quais traduzimos o conhecimento para linguagem acessível, disponibilizado nas redes sociais. Nosso alcance ultrapassou as expectativas e contabilizou mais de 123.482 interações com a população. A ação aproximou realidades e promoveu saúde, conectando a universidade à comunidade por meio da tecnologia

Estudio mediante Simulación Dinámica del Equilibrado de Motores de Combustión Interna Alternativos

El trabajo consiste en la realización de diferentes modelos de Motores de Combustión Interna Alternativos mediante el programa de Simulación Dinámica de Sistemas Multicuerpo Adams/View, partiendo de una serie de piezas del mecanismo biela-manivela-deslizadera, que serán comunes a todos los modelos. Los modelos de motores serán en línea, en V, bóxer y radiales, con diferentes números de cilindros. En estos modelos se comprobará el desequilibrio existente y se comparará con las expresiones analíticas que se encuentran en la bibliografía de la Teoría de Máquinas. Sobre los modelos se aplicarán las diferentes técnicas de equilibrado, tanto pasivo como activo y se determinarán las configuraciones más ventajosas para cada tipo de motor de cara a conseguir su equilibrado de la manera más sencilla. En aquellos que el equilibrado completo no sea posible, se aplicarán técnicas de optimización para conseguir la mayor compensación de dicho desequilibrio.Barella Ortiz, D. (2017).

Fine Tuning the Optical Properties of Single Au Nanoparticles by Plasmon-Driven Growth in Closed-Loop Control

The morphology and composition of metallic nanoparticles (NPs) determine their optical response, so finely controlling them at the single particle level is the key to achieve tailored functionalities. Here, the control of plasmon-driven growth of Au NPs is studied by live monitoring their photoluminescence emission in a closed-loop. It is found that the final emission maximum of single NPs can be tuned between 550 and 580 nm with a precision of 2–3 nm, and that the tuning is also reflected in their scattering maximum. In comparison to controlling the growth by irradiation time and/or reaction conditions, the closed-loop control delivers superior reproducibility and a three to fourfold higher precision in the final properties of the NPs.Fil: Martínez, Luciana Paula.
