Origem e identidade em <i>Noite vertical</i>, de Zetho Cunha Gonçalves
Authors: CARVALHO ANDRÉA DE 
Published: July 2024

RESUMO: O presente ensaio tem por objetivo analisar poemas selecionados do livro Noite vertical, de Zetho Cunha Gonçalves, que sublinhem características dos conceitos de origem e identidade. Para tanto, cabe, primeiramente, observar aspectos teóricos que fundamentem o argumento de que origem e identidade não se dão de forma estanque. A coleção de memórias (individuais e coletivas) expressas pelo eu-lírico ao longo do livro ressaltam o movimento (a dança) de busca por significados metafóricos que possibili-tem sua identificação, a despeito de uma origem geográfica. Argumento, portanto, que o livro estende ao público leitor o sentimento de não pertencimento, tão comum àque-les que vivenciaram a diáspora em África (a exemplo do próprio poeta) e abre a possibi-lidade de um novo (re)conhecer do eu em si através (e por causa) de sua transitividade.

ABSTRACT: This study aims to read selected poems from Noite vertical, by Zetho Cunha Gonçalves, that highlight aspects of the concepts of origin and identity. Thus, observing theoretical aspects that support the argument that origin and identity are not inflexible concepts. The collection of memories (both individual and collective) expressed by the poetic self throughout the book seems to pursue metaphorical meanings for identity, beyond geographical origin. Therefore, we argue that the book extends to the reader the feeling of displacement, so commonly experienced by those who lived through the African diaspora (such as the poet himself), enabling a new form of recognition of the self through (and because) of its fluidity.

A Obra Integral nos Programas de Português do Ensino Secundário. Fragilidades de um Domínio Curricular Oficialmente Sólido
Authors: MATEUS RUI MANUEL AFONSO 
Published: July 2024

RESUMO: Seja entendida como competência ou como modalidade particular de leitura, a educação literária encontra hoje nas obras integrais um objeto de difícil escolarização. Por assentar num corpus de adesão não imediata por parte dos alunos e em exercícios que a leitura natural descarta, o estudo de obras integrais tem sido tratado e programado de formas muito diversas em diferentes sistemas de ensino. Em Portugal, o atual quadro de regulação do ensino não particulariza o trabalho a fazer nesta modalidade de leitura, embora consagre o seu lugar no currículo, pelo que uma análise comparativa da situação portuguesa com a de outras realidades europeias permitirá lançar alguma luz sobre os pressupostos e as tendências mobilizadas na abordagem a um dos problemas didáticos atualmente mais sensíveis no ensino da literatura.
PALAVRAS-CHAVE: educação literária, leitura integral, ensino da literatura, cânone escolar
ABSTRACT: Whole books are an object of difficult schooling in the context of literary education, considered either as a skill or as a particular reading mode. Because it depends on a corpus to which students do not adhere immediately and on activities discarded in natural reading, the study of whole books has been diversely treated and programmed in different school systems. In Portugal, the current syllabus does not regulate, in particular terms, the work expected in this reading feature, although it establishes its place in the curriculum. Thus, an approach that compares the Portuguese situation to those in similar European school systems may cast some light upon the assumptions and the trends that feature one of today’s most serious problems in literature teaching.

A Dama do Pé-de-Cabra desde a Idade Média até ao Século XXI – uma Proposta Intermedial e Interdisciplinar para Decolonizar o Ensino de Literatura e Cultura Portuguesas
Authors: BALTRUSCH BURGHARD 
Published: July 2024

RESUMO: Este estudo propõe esboçar as linhas gerais de uma extensa unidade didáctica para o ensino de literatura portuguesa, que visa desconstruir os estereótipos presentes na versão romântica da Dama do Pé-de-Cabra de Alexandre Herculano. Estabelece-se uma matéria literária composta pela lenda medieval no Livro de Linhagens, a versão de Herculano no século XIX e, no século XXI, do conto “Fascinação,” de Hélia Correia, incluindo também os ciclos de pinturas de Paula Rego e Adriana Molder. Um dos principais objectivos é mostrar como a representação da mulher, na história de recepção desta matéria literária, atravessou um processo que começou com uma caracterização positiva que se tornou negativa por influência da religião e do patriarcalismo, e como a sua protagonista foi reabilitada e novamente empoderada no século XXI através das artes plásticas. Argumenta-se que esta matéria se revela idónea para a desconstrução e actualização do cânone literário no ensino através de um feminist stand point.
PALAVRAS-CHAVE: Dama do Pé-de-Cabra, Livro de Linhagens, Alexandre Herculano, Hélia Correia, Paula Rego, Adriana Molder
ABSTRACT: This study proposes to outline an extensive didactic unit for the teaching of Portuguese literature, which aims to deconstruct the stereotypes of the romantic version of the Dame with de Goat’s Foot by Alexandre Herculano. The literary matter is composed by the medieval legend established in the Book of Lineages, the 19th century version of Herculano, and the 21st century short story “Fascinação,” by Hélia Correia, and the cycles of paintings by Paula Rego and Adriana Molder. One of the main objectives is to show how the representation of women in the history of reception of this literary matter went through a process that began with a positive characterization that turned negative, due to the influence of religion and patriarchy, and how its protagonist was rehabilitated and empowered again in the 21st century through the visual arts. It is argued that this subject is suitable for the deconstruction and updating of the literary canon in teaching through a feminist standpoint.

Propósitos reglamentarios sobre la igualdad de género en la gestión cooperativa
Authors: Vázquez Ruano Trinidad 
Published: July 2024

Las cooperativas -como entidades de economía social- priorizan los intereses de las personas socias y/o del fin social sobre el capital siguiendo el contenido de los Principios formulados por la Alianza Cooperativa Internacional (ACI). De entre estos últimos, y al objeto de este análisis, interesa prestar especial atención tanto al principio de gestión democrática y participativa en la entidad cooperativa, como al principio de igualdad, lo que en líneas generales implica la ausencia de desigualdad o discriminación. De este modo, con independencia del género, la persona que ostenta la condición de socia está facultada para participar en la actividad cooperativizada y en la estructura orgánica formando parte de los órganos sociales que la gestionan. La actual propuesta de reforma normativa -que pretende ser un impulso de la economía social (Anteproyecto de Ley Integral)- tiene como una de sus líneas prioritarias la adecuación del texto nacional a las vigentes exigencias y condicionantes de carácter económico y social. En consecuencia, y atendiendo al principio cooperativo de igualdad, se propugna la efectividad del mismo entre hombres y mujeres y, en particular, en cuanto a su significación en la gestión de la entidad cooperativa.
Impact of land use change on the diurnal cycle climate of the Canadian Prairies

Published: October 2013

AbstractThis paper uses hourly observations from 1953 to 2011 of temperature, relative humidity, and opaque cloud cover from 14 climate stations across the Canadian Prairies to analyze the impact of agricultural land use change on the diurnal cycle climate, represented by the mean temperature and relative humidity and their diurnal ranges. We show the difference between the years 1953–1991 and 1992–2011. The land use changes have been largest in Saskatchewan where 15–20% of the land area has been converted in the past four decades from summer fallow (where the land was left bare for 1 year) to annual cropping. During the growing season from 20 May to 28 August, relative humidity has increased by about 7%. During the first 2 months, 20 May to 19 July, maximum temperatures and the diurnal range of temperature have fallen by 1.2°C and 0.6°C, respectively, cloud cover has increased by about 4%, reducing surface net radiation by 6 W m−2, and precipitation has increased. We use the dry‐downs after precipitation to separate the impact of cloud cover and show the coupling between evapotranspiration and relative humidity. We estimate, using reanalysis data from ERA‐Interim, that increased transpiration from the larger area of cropland has reduced the surface Bowen ratio by 0.14–0.2. For the month on either side of the growing season, cloud cover has fallen slightly; maximum temperatures have increased, increasing the diurnal temperature range and the diurnal range of humidity.
Approach to Fabricating Thermoplastic Polyurethane Blends and Foams with Tunable Properties by Twin‐Screw Extrusion and Microcellular Injection Molding

Published: October 2013

ABSTRACTThermoplastic polyurethane (TPU) has been widely used in many applications because of its broad range of properties. However, synthesis of TPU with desirable properties is time consuming and only produces limited quantities. In this paper, twin‐screw extrusion was used to produce TPU blends of varying soft and hard segments with tunable properties. Foamed samples of TPU blends were produced by microcellular injection molding. Multiple characterization tests were performed to confirm the miscibility and tunability of the blends. It was confirmed that soft and hard TPUs were compatible at ratios of 2:1 and 1:2, but partially miscible at a ratio of 1:1. Rigidity increased while the shape‐recovery rate decreased with increasing the hard TPU content. The blend ratio influenced the foaming morphology, solid skin‐layer thickness, as well as mechanical properties. It was found that microcellular injection molding could reduce the injection‐shot volume without sacrificing too much mechanical property and, compared with their solid counterparts, the foamed blends could retain mechanical properties better than foamed pure TPUs. Decomposition and degradation behaviors were also studied. The biocompatibility of soft and hard TPU‐foamed samples, which could be potentially used as tissue engineering scaffolds, was confirmed by fibroblast cytotoxicity test. © 2013 Wiley Periodicals, Inc.

Effects of fullerene derivatives on the gas permeability of thermoplastic polyurethane elastomers
Authors: Dobashi Ryohei , Matsunaga Katsuji , Tajima Masahiro 
Published: October 2013

ABSTRACTIn an effort to improve the gas barrier properties of thermoplastic polyurethane (TPU) elastomers, fullerene derivatives were added as fillers, and the resulting O2 and CO2 permeabilities were analyzed. The addition of 5 wt % polyhydroxylated fullerene {fullerenol [C60(OH)n] mixture, where n = 6–12} decreased the gas permeability by approximately 10–20%. According to the hole volumes computed with the results from positron annihilation lifetime spectroscopy, the addition of fullerene derivatives did not produce any changes in the hole volumes of the TPUs. Thus, the reduction in the TPU gas permeability was not caused by changes in the hole volumes. Instead, an inhibited diffusion of gas molecules by fullerene particles was deduced as the cause of the decrease in gas permeability from changes in the diffusion coefficient with temperature. The addition of urethanized fullerene, prepared through the chemical modification of fullerenol, markedly affected the TPU gas barrier properties. As compared to fullerenol addition, the gas barrier properties improved approximately fourfold for O2 and approximately fivefold for CO2. These results suggest that the dispersability of urethanized fullerene in TPU was higher than that of fullerenol. We found that the gas barrier properties were independent of the structure of polyol. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2014, 131, 39986.

Published: October 2013

ABSTRACTMannose‐rhodamine (Rh) conjugate (80% yield) was synthesized in a one‐pot reaction and immobilized onto magnetic polymeric nanoparticles (MPNP; 43% magnetic content) of poly(styrene/divinyl benzene/acrylic acid). The resulting nanoparticles contained MPNP as a substrate, mannose as an E. coli receptor and Rh as a fluorescent signaling unit. TEM imaging clearly demonstrated that multiple mannose‐Rh MPNPs could be captured by E. coli strain ORN178. The fluorescent signal from captured nanoparticles was emitted at 580 nm. These results indicate that mannose‐Rh MPNP offers a simple and rapid strategy for bacterial detection. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2014, 131, 40012.

AbstractThe biotransformations of (RS)‐linalool (1), (S)‐citronellal (2), and sabinene (3) with fungi isolated from the epicarp of fruits of Citrus genus of the Amazonian forest (i.e., C. limon, C. aurantifolia, C. aurantium, and C. paradisiaca) are reported. The more active strains have been characterized, and they belong to the genus Penicillium and Fusarium. Different biotransformation products have been obtained depending on fungi and substrates. (RS)‐Linalool (1) afforded the (E)‐ and (Z)‐furanlinalool oxides (7 and 8, resp.; 39 and 37% yield, resp.) with Fusarium sp. (1D2), 6‐methylhept‐5‐en‐2‐one (4; 49%) with F. fujikuroi, and 1‐methyl‐1‐(4‐methypentyl)oxiranemethanol (6; 42%) with F. concentricum. (S)‐Citronellal (2) gave (S)‐citronellol (12; 36–76%) and (S)‐citronellic acid (11; 5–43%) with Fusarium species, while diastereoisomeric p‐menthane‐3,8‐diols 13 and 14 (20 and 50% yield, resp.) were obtained as main products with Penicillium paxilli. Finally, both Fusarium species and P. paxilli biotransformed sabinene (3) to give mainly 4‐terpineol (19; 23–56%), and (Z)‐ and (E)‐sabinene hydrates (17 (3–21%) and 18 (11–17%), resp.).
Identification and Quantitation of New Glutamic Acid Derivatives in Soy Sauce by UPLC/MS/MS
Authors: Frerot Eric , Chen Ting 
Published: October 2013

AbstractGlutamic acid is an abundant amino acid that lends a characteristic umami taste to foods. In fermented foods, glutamic acid can be found as a free amino acid formed by proteolysis or as a non‐proteolytic derivative formed by microorganisms. The aim of the present study was to identify different structures of glutamic acid derivatives in a typical fermented protein‐based food product, soy sauce. An acidic fraction was prepared with anion‐exchange solid‐phase extraction (SPE) and analyzed by UPLC/MS/MS and UPLC/TOF‐MS. α‐Glutamyl, γ‐glutamyl, and pyroglutamyl dipeptides, as well as lactoyl amino acids, were identified in the acidic fraction of soy sauce. They were chemically synthesized for confirmation of their occurrence and quantified in the selected reaction monitoring (SRM) mode. Pyroglutamyl dipeptides accounted for 770 mg/kg of soy sauce, followed by lactoyl amino acids (135 mg/kg) and γ‐glutamyl dipeptides (70 mg/kg). In addition, N‐succinoylglutamic acid was identified for the first time in food as a minor compound in soy sauce (5 mg/kg).

Published: October 2013

AbstractHierarchical CaCo2O4 nanofibers (denoted as CCO‐NFs) with a unique hierarchical structure have been prepared by a facile electrospinning method and subsequent calcination in air. The as‐prepared CCO‐NFs are composed of well‐defined ultrathin nanoplates that arrange themselves in an oriented manner to form one‐dimensional (1D) hierarchical structures. The controllable formation process and possible formation mechanism are also discussed. Moreover, as a demonstration of the functional properties of such hierarchical architecture, the 1D hierarchical CCO‐NFs were investigated as materials for lithium‐ion batteries (LIBs) anode; they not only delivers a high reversible capacity of 650 mAh g−1 at a current of 100 mA g−1 and with 99.6 % capacity retention over 60 cycles, but they also show excellent rate capability with respect to counterpart nanoplates‐in‐nanofibers and nanoplates. The high specific surface areas as well as the unique feature of hierarchical structures are probably responsible for the enhanced electrochemical performance. Considering their facile preparation and good lithium storage properties, 1D hierarchical CCO‐NFs will hold promise in practical LIBs.

On the empirical efficiency of local MCMC algorithms with pools of proposals
Authors: Bédard Mylène , Mireuta Matei 
Published: October 2013

AbstractIn an attempt to improve on the Metropolis algorithm, various MCMC methods involving pools of proposals, such as the multiple‐try Metropolis and delayed rejection strategies, have been proposed. These methods generate several candidates in a single iteration; accordingly they are computationally more intensive than the Metropolis algorithm. In this paper, we consider three samplers with pools of proposals—the multiple‐try Metropolis algorithm, the multiple‐try Metropolis hit‐and‐run algorithm, and the delayed rejection Metropolis algorithm with antithetic proposals—and investigate the net performance of these methods in various contexts. To allow for a fair comparison, the study is carried under optimal mixing conditions for each of these samplers. The algorithms are used in the contexts of Bayesian logistic regressions, inference for a linear regression model, high‐dimensional hierarchical model, and bimodal distribution.

Published: October 2013

AbstractPhagocytosis is central to immunity however a rapid and standardized method is much needed for quantitative assessment of the phagocytic process. We describe a real‐time flow cytometric method to quantitate the phagocytosis of fluorescent latex beads by human monocytes in serum‐free conditions. Effects of buffer composition, temperature, pH, and bead surface on phagocytic rate are described. The innate phagocytic ability of human monocytes from single subjects measured by this method was relatively stable over many months although phagocytosis rate varied as much as two‐fold between individuals. Comparable results were obtained with a simplified method using several mL of whole blood which is suitable for routine clinical application. This method also allows two‐color flow cytometric measurement of cytosolic calcium levels during the phagocytic uptake of fluorescent beads. © 2013 International Society for Advancement of Cytometry
Development of an Information Projection Interface Using a Projector–Camera System
Authors: Goto Hiroki , Takemura Daisuke , Kawasaki Yuzo , Nakamura Akio 
Published: October 2013

SUMMARYThis paper proposes an interface system that enables a user to input and obtain information independent of position within a certain area in an environment with a projector–camera system. Hand gestures detected in the image are used as a cue to start the system, to distinguish gestures based on the user's intention to operate the system from other daily‐life motions, and to specify the position of the user's hand. Hand gesture detection is implemented based on a combination of the background subtraction method and skin color extraction. The user can designate the projection area freely on a flat surface in the environment with his/her hand. The projector is mounted on a pan‐tilt unit that projects information according to the user's indications. Then, the user's fingertip is detected using simple template matching and he/she interacts with the projected information to input commands without any equipment. As one application, we developed an interface system to operate electrical appliances such as a television intuitively in an everyday environment. © 2013 Wiley Periodicals, Inc.
