Congruence in Music and Movement Enhances the Perception of Sports Routine Quality
Authors: Loo Fung Chiat , Loo Fung Ying , Chua Yan Piaw 
Published: December 2019

Most studies of music and sports relate to the ergogenic effect of synchronization between music and movement in repetitive sports activities. As in dance, music is clearly important for sports routines that involve choreography. This study performs an experiment involving a rhythmic gymnastics routine to investigate whether increasing the congruence between music and movement enhances the quality of sports routines from a musical perspective. In preparing the video stimulus, the original music accompaniment was replaced with a new composition to increase the congruence between music and movement using six musical parameters that parallel dance, including tempo, rhythm, phrasing, accent, direction and dynamic. Fifty-two undergraduate music majors participated in the study and evaluated two videos of the same routine, one with the original music and the other with the new music. The participants completed a three-part questionnaire: the first part evaluates the perceived congruence between music and movement in terms of the six parameters, the second part evaluates acrobatic qualities, and the third part evaluates athletic qualities. The results show that the intended congruence was perceived as significantly improved in the routine with the new accompaniment, and both the acrobatic and sports qualities were also perceived as significantly improved.

THERMAL TRANSPORT IN CROSS-LINKED ELASTOMERS SUBJECTED TO ELONGATIONAL DEFORMATIONS
Authors: Venerus David C. , Simavilla David Nieto , Schieber Jay D. 
Published: December 2019

ABSTRACT
Investigations on thermal transport in cross-linked elastomers subjected to elongational deformations are reviewed and discussed. The focus is on experimental research, in which the deformation-induced anisotropy of the thermal conductivity tensor in several common elastomeric materials is measured using novel optical techniques developed in our laboratory. These sensitive and noninvasive techniques allow for the reliable measurement of thermal conductivity (diffusivity) tensor components on samples in a deformed state. When combined with measurements of the stress in deformed samples, we are able to examine the validity of the stress–thermal rule, which predicts a linear relationship between the thermal conductivity and stress tensor in deformed polymeric materials. These results are used to shed light on possible underlying mechanisms for anisotropic thermal transport in elastomers. We also present results from a novel experimental technique that show evidence of a deformation dependence of the heat capacity, which implies that, in addition to the usual entropic contribution, there is an energetic contribution to the stress in deformed elastomers.

Published: December 2019

Introdução: A era digital demanda por novas propostas e abordagens técnicas associadas à utilização da Tecnologia da Informação na recuperação e apropriação da informação no contexto da Web de Dados. O desenvolvimento dessa área permitirá um maior entendimento dos recursos da tecnologia colaborativa utilizados em ambientes informacionais digitais na organização da informação e do conhecimento. A inserção dessas tecnologias consiste em inovações que devem estar vinculadas à tradição e à missão das bibliotecas e dos repositórios digitais. Objetivos: Este trabalho tem por objetivo discutir os resultados parciais de projeto de pesquisa conduzido no Departamento de Informação e Cultura da Escola de Comunicações e Artes da Universidade de São Paulo e está estruturado em três fases: (i) Modelos de busca, acesso, e recuperação da informação; (ii) Infraestrutura tecnológica em bibliotecas digitais; e (iii) Ferramentas de busca e recuperação da informação na Web de Dados. Metodologia: Identificar e discutir as tendências nos modelos de busca da informação, em especial interesse aqueles que influenciam o contexto da organização e recuperação da informação, de modo que o uso da tecnologia possa proporcionar a criação e agregação de valor aos modelos de busca, acesso, recuperação e apropriação da informação na Web de Dados. Conclusões: Atualmente se conhece muita coisa sobre planejamento, aquisição, organização, controle e desenvolvimento de coleções, mas muito pouco sobre como o usuário interage com os sistemas ou para que fins, e como a informação, que é a matéria-prima do sistema, está sendo utilizada. Torna-se evidente a necessidade de aprofundar os estudos e pesquisas que permitam entender os modelos de busca e apropriação da informação em um cenário dependente de recursos computacionais na Web inteligente.

La formación de la ciudadanía en competencia digital interesa a administraciones nacionales y supranacionales. En los últimos años se han invertido ingentes cantidades económicas en la dotación de infraestructura y en I+D+I para el desarrollo tecnológico en distintos sectores de la sociedad. La integración de dispositivos digitales en la sociedad ha impacto en las políticas educativas de muchos países, llevándolos a considerar la competencia digital como aspecto clave en la enseñanza obligatoria y esencial para la inclusión social. En este artículo, se presentan los resultados de una investigación realizada en cuatro centros de Educación Primaria de Valencia y Galicia, reconocidos por su trayectoria innovadora en el uso de las TIC. El objetivo es identificar y analizar las visiones que la comunidad educativa de cada escuela tiene sobre la competencia digital que está adquiriendo el alumnado participante en prácticas educativas mediadas por TIC. Para la recogida de información se empleó metodología cualitativa, específicamente entrevistas a profesorado, familias y alumnado. Los resultados reflejan modelos diferentes de trabajo y conceptualización de la competencia digital. Todos ellos reconocen su relevancia para la inclusión en la sociedad del futuro y desmitifican su rol hegemónico en el aprendizaje escolar.
The training of citizens in digital competence is of interest to national and supranational administration. In recent years enormous amounts of money have been put into the provision of facilities and I+D+I for technological development in different sectors of society. The integration of digital devices in the industry, communication and society has had a profound impact on educational policies in many countries, making them consider the digital competence as a key in the compulsory education and essential to the social inclusion. This article shows the results of a research conducted in four primary schools from Valencia and Galicia that are recognized because of their innovative trajectory in the use of ICTs. The aim is to identify and analyse the visions of the education community members from each school about the digital competence which is being acquired by the students involved in educational practices mediated by ICTs. To collect the information, it was used a qualitative method based on interviews with teachers, families and students. The results reflect different work models and concepts about the digital competence. It is recognized that the ICTs are relevant to the inclusion in the society of tomorrow and it has been demystified their hegemonic role on school learning.
Prácticas de RSE en cooperativas. Experiencias y resultados mediante el estudio de casos
Authors: Pérez-Sanz Francisco Javier , Gargallo-Castel Ana F. , Esteban-Salvador María Luisa 
Published: December 2019

La conducta observada en las organizaciones que conforman el entramado de la Economía Social ha supuesto un precedente en actuaciones y prácticas que representan una forma de hacer empresa basada en la responsabilidad social, incluidas sus múltiples acepciones y enfoques. Asimismo, se percibe un creciente interés en la llamada Responsabilidad Social de la Empresa (RSE), un modelo de gestión implantado en diversos tipos de organizaciones, con y sin fines lucrativos, que lleva consigo el compromiso con un conjunto de valores ligados a todos sus grupos de interés. En el marco de la Economía Social, las cooperativas operan en conformidad con los criterios, valores y principios de RSE, interés por la comunidad y servicio a sus miembros, no solamente en la esfera económica, sino también en el ámbito social y medioambiental. Múltiples trabajos manifiestan la concordancia entre el desarrollo de las políticas de RSE en sus tres vertientes (económica, social y ambiental) y los valores y principios cooperativos enunciados por la Alianza Cooperativa Internacional (ACI, 1995). Estos estudios avalan la afirmación de que la propia naturaleza de las cooperativas implica un comportamiento socialmente responsable. Asumidos estos postulados, el objetivo del presente trabajo es observar y constatar el cumplimiento efectivo de los mismos en cooperativas de diferentes sectores y entornos, cuestión que conlleva el análisis de la gestión integral de las actuaciones inherentes de RSE, derivadas de sus relaciones con los distintos agentes, según la Teoría de los grupos de interés (Turker, 2009). Adicionalmente, las cooperativas deben buscar la supervivencia mediante sus resultados económicos plasmados en la obtención de unos excedentes y una rentabilidad adecuados (López y Marcuello, 2006), con la finalidad de prestar servicios a los socios a lo largo del tiempo, y todo ello en sintonía con las demandas de los distintos grupos de interés. Por estos motivos, el estudio contrasta la aplicación de la RSE con la obtención de resultados económicos en un entorno de crisis económica. Mediante una metodología de estudio de casos, se han seleccionado seis cooperativas españolas pertenecientes a diversos sectores, para analizar sus memorias y cuentas de resultados, con el objeto de identificar relaciones entre sus comportamientos de RSE y los resultados económico-financieros obtenidos en un periodo de tiempo determinado.
UN POLO «PERVERSO» DEL LENGUAJE VAGO: EL ENMASCARAMIENTO EN EL DISCURSO POLÍTICO
Authors: Cortés Rodríguez Luis 
Published: December 2019

El lenguaje vago se caracteriza por su polaridad, que va de una función «positiva», relacionada con la cortesía, la espontaneidad y la fluidez expresiva (especialmente en la conversación), a otra «perversa», con la que se pretende enmascarar datos precisos, ciertas realidades que en un determinado momento conviene mitigar o encubrir. En este artículo, nos vamos a ocupar de ambas funciones, si bien nos centraremos en esta segunda, la negativa: una maniobra más entre las múltiples acciones manipuladoras que se pueden llevar a cabo a partir de los mecanismos lingüísticos. Para ejemplificar el resultado de tal función, nos valdremos de uno de sus campos de acción preferido: el discurso político.

AbstractBiodegradable nanoprodrugs, inheriting the antitumor effects of chemotherapy drugs and overcoming the inevitable drawback of side effects on normal tissues, hold promise as next‐generation cancer therapy candidates. Biodegradable nanoprodrugs of transferrin‐modified MgO2 nanosheets are developed to selectively deliver reactive oxygen species to cancer cells for molecular dynamic therapy strategy. The nanosheets favor the acidic and low catalase activity tumor microenvironment to react with proton and release nontoxic Mg2+. This reaction simultaneously produces abundant H2O2 to induce cell death and damage the structure of transferrin to release Fe3+, which will react with H2O2 to produce highly toxic ·OH to kill tumor cells.

AbstractAdvanced redox‐polymer materials offer a powerful platform for integrating electroseparations and electrocatalysis, especially for water purification and environmental remediation applications. The selective capture and remediation of trivalent arsenic (As(III)) is a central challenge for water purification due to its high toxicity and difficulty to remove at ultra‐dilute concentrations. Current methods present low ion selectivity, and require multistep processes to transform arsenic to the less harmful As(V) state. The tandem selective capture and conversion of As(III) to As(V) is achieved using an asymmetric design of two redox‐active polymers, poly(vinyl)ferrocene (PVF) and poly‐TEMPO‐methacrylate (PTMA). During capture, PVF selectively removes As(III) with exceptional uptake (>100 mg As/g adsorbent), and during release, synergistic electrocatalytic oxidation of As(III) to As(V) with >90% efficiency can be achieved by PTMA, a radical‐based redox polymer. The system demonstrates >90% removal efficiencies with real wastewater and concentrations of arsenic as low as 10 ppb. By integrating electron‐transfer through the judicious design of asymmetric redox‐materials, an order‐of‐magnitude energy efficiency increase can be achieved compared to non‐faradaic, carbon‐based materials. The study demonstrates for the first time the effectiveness of asymmetric redox‐active polymers for integrated reactive separations and electrochemically mediated process intensification for environmental remediation.

AbstractTransition metal oxides (TMOs) with high work function (WF) show promising properties as unipolar p‐type contacts for transition metal dichalcogenides. Here, ambipolar field‐effect transistors (FETs) enabled by bilayer WSe2 with self‐assembled TMOs (WO2.57) as contacts are reported. Systematic material characterizations demonstrate the formation of WO2.57/WSe2 heterojunctions around nanoflake edges with Se atoms substituted by O atoms after air‐exposure, while pristine properties of WSe2 almost sustain in inner domains. As‐fabricated FETs exhibit both polarities, implying WO2.57 with lowered WF at edges can serve as both the p‐type and n‐type contact for inner WSe2. Noteworthy, greatly reduced contact resistance and enhanced channel current are achieved, compared to the devices without WO2.57 contacts. Linear drain–source current relationship from 77 to 300 K indicates the ohmic contact between edge WO2.57 and inner WSe2. Density functional theory calculations further reveal that the WO2.57/WSe2 heterojunction forms a barrier‐less charge distribution. These nm‐scale FETs possess remarkable electrical conductivity up to ≈2600 S m−1, ultra‐low leakage current down to ≈10−12 A, robustness for high voltage operation, and air stability, which even outperform pristine WSe2 FETs. Theoretical calculations reveal that the high conductivity is exclusively attributed to the air‐induced WO2.57 and its further carrier injection to WSe2.

Published: December 2019

AbstractA programmable hybrid circuit is proposed, which is composed of two reconfigurable spoof surface plasmon polariton (SPP) waveguides loaded with varactor diodes and a substrate integrated waveguide (SIW). By manipulating their dispersion behaviors, the band‐pass effect is achieved in the hybrid circuit, in which the upper and lower cutoff frequencies are determined by the SPP waveguide and SIW, respectively. When two SPP waveguides are configured to have the same cutoff frequency that is higher than the SIW's cutoff, the proposed circuit can realize a power division; when one SPP waveguide is reconfigured to reject the waves from SIW, this circuit will be a band‐pass filter. As a typical application, a logic “OR” gate with 2‐bit coding is designed by programming the bias voltages applied to the varactor diodes loaded on the unit structures of the SPP waveguides. All functions are demonstrated by measurement results that agree with numerical simulations very well. The work provides more potential applications in multifunctional integrated circuits and digital communication systems.

ABSTRACTComposite materials with a high permittivity (high‐k) and low dielectric loss represent an important research direction for the rapid development of modern electronic. This article is about high‐k composite with low dielectric loss (dielectric constant is approximately 11, and dielectric loss is only 0.02 at 1 MHz and about 50 wt % of filler) based on a polytetrafluorethylene (PTFE) compounded with priderite (K1.46Ti7.2Fe0.8O16). The dielectric permittivity about ε' ≈ 103 and the dielectric loss of tgδ ≈ 2 have been found for filler content about 50 wt % (30 vol %) and, respectively, ε' ≈ 11 and tgδ ≈ 0.02 for 1 MHz. To produce filler, amorphous potassium polytitanate was synthesized by molten salt method, modified in aqueous solution of iron sulfate, crystallized at 700 °C and further treated in the aqueous dispersion of PTFE. The obtained product was pressured, dried and investigated by X‐ray diffraction and scanning electron microscopy. Dielectric properties of the composite with different ceramic filler content (1–90 wt %) were studied using impedance spectroscopy in the frequency range of 10−2 to 106 Hz. The influence of frequency on electric conductivity, permittivity, and dielectric losses was analyzed taking into account the experimental data on porosity, apparent density obtained for the composites. © 2019 Wiley Periodicals, Inc.
