Authors: Pacheco Raquel , Moura Anabela , Soares Ana Isabel , Almeida Carlos 
Published: July 2019

Existe um consenso em torno do reconhecimento do cinema como meio de aquisição de uma literacia mediática. A problematização do cinema como expressão artística e da promoção da interdisciplinaridade entre as áreas da comunicação, do cinema e educação e da educação artística em particular que têm sido estabelecidas no âmbito do ensino das Ciências da Comunicação, tal como Lobo (1999), Pacheco (2016), Migliorin (2015) e outros argumentam, têm vindo a ser aplicadas na Escola Superior de Educação, do Instituto Politécnico de Viana do Castelo (ESE-IPVC), a muitas outras áreas, como é o caso da formação de gestores nas áreas das artes e da cultura, dos especialistas dos cursos de luz, som e imagem e na formação de professores (Moura et al, 2017). Neste contexto, o objetivo deste artigo é analisar um projeto de investigação que se repete anualmente, quando confrontam os estudantes com o cinema documental e seus conceitos, a literacia cinematográfica, a análise de imagens fixas e em movimento, resultando na criação de filmes documentais a partir do texto de Almada Negreiros “Manifesto Anti Dantas”.
El proceso de enseñanza-aprendizaje de la Historia del Cine a través de una estrategia de storytelling y storydoing teatral aplicada al ámbito universitario

Published: July 2019

Las asignaturas relacionadas con la Historia suelen presentar dificultades para el alumnado y en ocasiones resultar tediosas por ser interpretadas como una recopilación de fechas y nombres a veces aparentemente inconexos. Con el objetivo de dinamizar y facilitar el proceso de aprendizaje significativo de la Historia del Cine se ha desarrollado el proyecto ‘El cine a través del storytelling y el teatro’ en el marco de la asignatura Realización del tercer curso de los Grados en Comunicación en EADE University of Wales en Málaga. Se ha aplicado una metodología que refuerza el trabajo sobre los aspectos teóricos relacionados con la Historia del Cine a través de una dinámica de role playing en la que el alumnado interpreta, dirige y realiza audiovisualmente textos teatrales en los que la trama y los personajes se centran en personalidades relevantes para el desarrollo del séptimo arte. Mediante una investigación cualitativa y cuantitativa se han estudiado los textos empleados y las percepciones del alumnado sobre esta práctica educativa que aplica el storytelling y lo combina con el storydoing para convertir a los alumnos en protagonistas del aprendizaje sobre cine.
Esta metodología aplicada a la enseñanza de contenidos sobre cine se ha revelado efectiva para transferir al alumnado conocimientos teóricos propios de la materia de un modo innovador al tiempo que desarrolla habilidades transversales relacionadas con la comunicación no verbal, la comunicación en público, el trabajo colaborativo y la técnica audiovisual.

Authors: Martínez Hierrezuelo Yailin , Ivanova Iotova Anelia , Martínez Valle Carlos 
Published: July 2019

La creación musical es uno de los elementos fundamentales de la educación musical y se manifiesta a través de los procesos de improvisación, elaboración de arreglos y composición musical. El objetivo de este trabajo es determinar el tratamiento que se le otorga a la creación musical en los currículos de educación primaria, enseñanzas elementales de música y escuelas de música de la Comunidad de Madrid. Para la realización de la investigación se siguieron las metodologías de tipo documental (estudio de los diferentes decretos) y comparado (análisis y medición de los datos, clasificados en dimensiones e indicadores de comparación). Los resultados muestran que los currículos de primaria y enseñanzas elementales presentan a la creación musical a través de la improvisación y la composición como objetivo, habilidad, medio de aprendizaje y evaluación, sin embargo carecen de orientaciones metodológicas concretas para trabajarla secuencial y didácticamente, y en las orientaciones metodológicas para las escuelas de música no se evidencia a la creación musical entre sus aspectos educativos fundamentales. Puede concluirse que la creación musical necesita mayor soporte metodológico y curricular, acorde a las demandas educativas actuales y en consonancia al carácter creativo del arte. El arte es creación y la educación musical no debería soslayar los procesos de los cuales emerge la música.

Failure to consider genetic structure in fish populations when collecting aquaculture broodstock can negatively affect fitness, and hence conservation and management goals. Here we used mitochondrial DNA from the 5’ end of the control region (D-loop) and four microsatellite markers to evaluate population genetic structure in the Mangrove Jack Lutjanus argentimaculatus with a view to guiding broodstock collection at the southern extremity of its east Australian range. There was no evidence of genetic structure within the entire tropical, subtropical and temperate east Australian distribution of L. argentimaculatus. Although this species may exhibit clinal morphological and life-history variation at its southern range limit, we did not detect wide- or fine-scale spatial genetic structure to indicate the presence of non-random evolutionary processes. Broodstock collection of L. argentimaculatus need not be geographically restricted in eastern Australia, but fisheries management should consider variation in life history and recruitment success at the species’ edge.

Published: July 2019

AbstractPurposeMagnetic resonance imaging (MRI) is the primary modality for targeting brain tumors in radiotherapy treatment planning (RTP). MRI is not directly used for dose calculation since image voxel intensities of MRI are not associated with EDs of tissues as those of computed tomography (CT). The purpose of the present study is to develop and evaluate a tissue segmentation‐based method to generate a synthetic‐CT (sCT) by mapping EDs to corresponding tissues using only T1‐weighted MR images for MR‐only RTP.MethodsAir regions were contoured in several slices. Then, air, bone, brain, cerebrospinal fluid (CSF), and other soft tissues were automatically segmented with an in‐house algorithm based on edge detection and anatomical information and relative intensity distribution. The intensities of voxels in each segmented tissue were mapped into their CT number range to generate a sCT. Twenty‐five stereotactic radiosurgery and stereotactic ablative radiotherapy patients’ T1‐weighted MRI and coregistered CT images from two centers were retrospectively evaluated. The CT was used as ground truth. Distances between bone contours of the external skull of sCT and CT were measured. The mean error (ME) and mean absolute error (MAE) of electron density represented by standardized CT number was calculated in HU.ResultsThe average distance between the contour of the external skull in sCT and the contour in coregistered CT is 1.0 ± 0.2 mm (mean ± 1SD). The ME and MAE differences for air, soft tissue and whole body voxels within external body contours are −4 HU/24 HU, 2 HU/26 HU, and −2 HU/125 HU, respectively.ConclusionsA MR‐sCT generation technique was developed based on tissue segmentation and voxel‐based tissue ED mapping. The generated sCT is comparable to real CT in terms of anatomical position of tissues and similarity to the ED assignment. This method provides a feasible method to generate sCT for MR‐only radiotherapy treatment planning.

Published: July 2019

AbstractHydrophile–lipophile balance (HLB) has a great influence on the self‐assembly and physicochemical properties of amphiphiles, thus affecting their biological effects. It is shown that amphiphilic nanoparticles (NPs) with a moderate HLB value display enhanced stability and highly efficient tumor retention. 2,2‐Bis(hydroxymethyl)propionic acid hyperbranched poly(ethylene glycol) (PEG)–pyropheophorbide‐a (Ppa) amphiphiles (G320P, G310P, G220P, and G210P) are synthesized with a tunable HLB value from 6.1 to 9.9 by manipulating the number of generation of dendrons (G2 or G3) and the molecular weight of PEG chains (10 or 20 kDa). Molecular dynamics simulations reveal that G320P and G210P with a moderate HLB value (8.0 and 7.8) self‐assemble into very stable NPs with a small solvent accessible surface area and high nonbonding interactions. G320P with a moderate HLB value (8.0) and a long PEG chain excels against other NPs in prolonging the blood circulation time of Ppa (up to 13‐fold), penetrating deeply into multicellular tumor spheroids and accumulating in tumors, and enhancing the PDT efficacy with a tumor growth inhibition of 96.0%. Rational design of NPs with a moderate HLB value may be implemented in these NP‐derived nanomedicines to achieve high levels of retention in tumors.

Published: July 2019

AbstractStretchable strain sensors have aroused great interest for their application in human activity recognition, health monitoring, and soft robotics. For various scenarios involving the application of different strain ranges, specific sensitivities need to be developed, due to a trade‐off between sensor sensitivity and stretchability. Traditional stretchable strain sensors are developed based on conductive sensing materials and still lack the function of customizable sensitivity. A novel strategy of mechanocombinatorics is proposed to screen the sensor sensitivity based on mechanically heterogeneous substrates. Strain redistribution over substrates is optimized by mechanics and structure parameters, which gives rise to customizable sensitivity. As a proof of concept, a local illumination method is used to fabricate heterogeneous substrates with customizable mechanics and structure parameters. A library of mechanocombinatorial strain sensors is created for extracting the specific sensitivity. Thus, not only is an effective strategy for screening of sensor sensitivity demonstrated, but a contribution to the mechanocombinatorial strategy for personalized stretchable electronics is also made.

Published: July 2019

AbstractIn this work, a scalable thermal imprinting method that allows to directly fabricate superhydrophobic polymer surfaces with superstrong resistance to harsh cleaning and mechanical abrasion is reported. A titanium (Ti) mold is produced by femtosecond laser processing to possess a hierarchical micro‐ and nanoscale pattern. Through thermal imprinting, this hierarchical pattern onto poly(propylene) sheets is able to be accurately reproduced, rending the polymer surface superhydrophobic. The imprinting method employed uses an aqueous ethanol solution of stearic acid to assist demolding, and periodically uses xylene to limit mold contamination and restore the mold to excellent condition for further imprinting. These strategies allow to repeatedly use the mold over 50 times without degradation. A range of durability tests are further performed, and showed that the produced suprehydrophobility on the poly(propylene) sheets exhibit excellent durability, withstanding brush washing, ultrasound cleaning, and sandpaper abrasion. The reported method can also be used to fabricate superhydrophobic surfaces of various thermoplastics that are broadly utilized in daily life.
The Facet Structure and Photochemical Reactivity of Arbitrarily Oriented Strontium Titanate Surfaces
Authors: Pisat Ajay S. , Salvador Paul A. , Rohrer Gregory S. 
Published: July 2019

AbstractSrTiO3 polycrystalline ceramics with polished surfaces are annealed at 1250 °C in air. This treatment causes the flat surfaces to break up into facets meeting at sharp edges and corners. An analysis of the orientations and topography of the faceted surfaces demonstrates that all are either {100} or {110} oriented. The {100} surfaces are photocathodically active and reduce Ag+ to Ag metal. The {110} surfaces are photoanodically active and oxidize Mn2+ and Pb2+ to Mn4+ and Pb4+, respectively. The chemical properties of both surfaces appear to be uniformly photocathodic or photoanodic. However, after annealing at 1100 °C with Sr3Ti2O7, the {110} facets have a combination of photocathodic and photoanodic terraces. The results show that the photocathodic‐to‐photoanodic surface area ratio, which influences the overall rate of a photochemical reaction, can be controlled for arbitrarily oriented SrTiO3 surfaces by using thermal treatments to create low index facets and to control the chemical terminations on these facets.

Published: July 2019

AbstractMetal ions are of significant importance in biomedical science. This study reports a new concept of cytomembrane‐mediated biospecific transport of metal ions without using any other materials. For the first time, cytomembranes are exploited for two‐step conjugation with metal ions to provide hybrid nanomaterials. The innate biofunction of cell membranes renders the hybrids with superior advantages over common vehicles for metal ions, including excellent biocompatibility, low immunogenic risk, and particularly specific biotargeting functionality. As a proof‐of‐concept demonstration, cancer cell membranes are used for in vivo delivery of various metal ions, including ruthenium, europium, iron, and manganese, providing a series of tumor‐targeted nanohybrids capable of photothermal therapy/imaging, magnetic resonance imaging, photoacoustic imaging, and fluorescence imaging with improved performances. In addition, the special structure of the cell membrane allows easy accommodation of small‐molecular agents within the nanohybrids for effective chemotherapy. This study provides a new class of metal‐ion‐included nanomaterials with versatile biofunctions and offers a novel solution to address the important challenge in the field of in vivo targeted delivery of metal ions.

Published: July 2019

AbstractA stretchable, flexible electroresponsive liquid‐crystal (LC) device with extremely simple structure is reported. It exhibits excellent light‐transmission control even during successive 45% stretching, which is due to the combination of a super‐strong LC gel network (5CB/POSS‐G1‐BOC) and transparent conductive electrodes composed of silver nanowires (AgNWs) embedded in polyurethane (PU). The uniaxial tensile deformation mechanism of the gel network is also explained by the uniform distribution of stress acting on the device at the macro level and the evenly distributed fibers obtained from LC gel at the micro level. The fibers can equally dissipate energy through a series of homogeneous complicated changes from long and levorotatory nanofibers to short and rod‐like nanofibers with an increasing stretch ratio from 0% to 900%, which is dubbed the “spiral dissipate energy” model. These results demonstrate the unique stretchable properties of LC gel and LC devices for a wide range of applications, including wearable devices and artificial skins.

Published: July 2019

AbstractFerroelectric‐field‐effect‐transistor (FeFET) memory, characterized by its nonvolatile, nondestructive readout operation and low power consumption, has attracted tremendous attention in the development of next‐generation random‐access memory. However, the electrical reading processes in conventional FeFETs may attenuate the ferroelectric (FE) polarization and lead to readout crosstalk. A photoelectric‐type FeFET memory with alternative readout through 2D black phosphorus (BP)/lead zirconate titanate (PZT) heterostructures is developed. Based on charge‐mediated electric‐field control, a unique polarization‐dependent photoresponse is observed, resulting in both positive photoconductivity (PPC) and negative photoconductivity (NPC) in a single device element via FE gating. This enables a nonvolatile photoelectric memory working in a novel “electrical writing‐optical reading” process mode. Furthermore, the device exhibits a reliable data retention (over 3.6 × 103 s) and fatigue (exceeding 500 cycles) performance with extremely low energy consumption (driving voltage <10 mV). The demonstrated BP/PZT heterostructure memory devices show a pathway to high‐performance photoelectric storage devices as light‐activated logic gates for on‐chip optical communications.

Published: July 2019

AbstractWith the remarkable progress in solution‐processed optoelectronics, high performance is required of the carrier transport/injection layer. Ternary oxides containing a variety of crystal structures, and adjustable composition that results in tunable optical and electrical properties, are one of the promising class of candidates to fulfill the requirements of carrier transport/injection layers for high‐performance and stable optoelectronic devices. Solution‐processed ternary oxides have seen considerable progress in recent decades, due to their advantages in the quest to design low‐cost, high‐performance, large‐scale, and stable optoelectronic devices. Herein, the recent advances of solution‐processed ternary oxides are reviewed. The first section consists of a brief introduction to the topic. In the following section, the fundamentals of the effect of tuning ternary oxide composition are summarized. Section three briefly reviews the synthesis approaches for preparing ternary oxides. Section four discusses the recent progress of solution‐processed ternary oxide as carrier transport/injection layer in optoelectronic devices (such as organic solar cells, perovskite solar cells, organic light emitting diodes, etc.). In this section, the impact of controlling ternary oxide composition on device performance and stability is highlighted. Finally, a brief summary and an outlook are given.

AbstractThe aim of this study was to describe satisfaction and quality of life (QOL) of young adults with arthrogryposis after leaving pediatric care. Twenty‐three adults with arthrogryposis multiplex congenital (AMC) followed at a single pediatric orthopedic hospital (average age 23.6 years; range 18–36 years; 9 males, 14 females) completed questionnaires related to demographics, mobility, and activities of daily living. The Patient Reported Outcomes Measure Information System and Satisfaction with Life Scale were utilized to evaluate QOL and life satisfaction. Eighty‐three percent reported general health as good/excellent, 30% lived independently, 69% were ambulatory in the community, and 57% were employed. QOL scores for physical function were lower, but other QOL scores were consistent with the general U.S. population. Average pain intensity was mild at 2.6 out of 10, with pain frequently reported in the legs and feet. Fifty‐six percent were satisfied to extremely satisfied with life. Five individuals who were dissatisfied with life also reported lower physical function, higher anxiety, depression and fatigue, and pain in multiple joints. Although most young adults with AMC presented with mild pain and limitations in physical function; overall, they reported good QOL. Findings from the current study will help clinicians anticipate the needs of individuals with AMC as they transition from pediatric to adult care.
