Zkušenosti žáků s výukou ve výkonových skupinách: kvalitativní výzkumná sonda
Authors: Navrátilová Jana
Published: June 2023

Cíle – Předkládaná studie je věnovaná problematice seskupování žáků v prostředí druhého stupně základních škol. Studie si klade za cíl popsat, jak žáci vypovídají o zkušenostech s výukou ve výkonových skupinách, a to především v porovnání s výukou, která probíhá v heterogenní třídě.
Metody – Studie je součástí projektu, který byl koncipován jako vícepřípadová studie mapující podobu seskupování žáků na druhém stupni ZŠ. V předloženém textu jsou prezentovány výsledky z jedné třídy, jedné základní školy, na které započalo výzkumné šetření. Studie vychází z dat získaných z individuálních (n=4) a párových rozhovorů (n=6) se žáky. Celkem je využito dat od 16 žáků.
Výsledky – Žáci z obou skupin jsou spokojenější ve výuce v homogenním seskupení na tolik, že preferují zintenzivnit výuku ve skupinách na úkor výuky ve společné třídě. Argumentují tím, že učitelé diferencují výuku pouze ve skupinách, které jsou k tomuto účelu údajně určeny. Výuka ve společné třídě diferencovaná podle žáků není. Optikou žáků se zdá, jako by učitelé centrovali svoje didaktické úsilí do kvality výuky ve skupinách a na diferencovanou výuku ve společné třídě zanevřeli. Ačkoli výuka ve výkonnostních skupinách lépe odpovídá vzdělávacím potřebám žáků v porovnání s výukou ve společné třídě, učitelé podle žáků někdy balancují nad tím, jakou míru podpory obě skupiny žáků potřebují. Tím, že učitelé výuku ve skupinách diferencují spíše podle očekávání o výkonech celé skupiny než podle skutečných výkonů jednotlivců, přestává výuka občas reagovat na individuální potřeby.
Závěry – Žákovský pohled ukazuje, že učitelé diferencují výuku spíše ve skupinách než ve společné třídě, nicméně v rámci skupiny již výuka diferencovaná není. Seskupení žáků do výkonových skupin může učitele svádět k užívání unifikovanějších didaktických postupů, které odpovídají potřebám a možnostem skupiny jako celku nikoli měnícím se potřebám jednotlivců uvnitř skupin.
Where to next with Australia’s News Media and Digital Platforms Mandatory Bargaining Code?
Authors: Dwyer Tim , Flew Terry , Wilding Derek
Published: June 2023

Taken at face value the introduction in 2021 of Australia’s News Media and Digital Platforms Mandatory Bargaining Code (“the Code”) may appear “world leading,” innovative, and, in general, a productive and strategic intervention to reverse the decline of public interest journalism. It is claimed that in the Australian news industry context, an annual transfer of around $200 million between two platform companies – Google and Meta – and news businesses has now been put in place (Sims, 2022). All major news media companies in Australia, if not smaller more independent ones, have greatly benefitted from the new Code, and anecdotally it appears that the funding has resulted in the creation of significant numbers of new journalists being hired. Yet the exact investment destination and ultimate beneficiaries of the funding are not known beyond the corporate walls of the recipients. The article points to the transparency and sustainability problems inherent to the new Code, arguing that an alternative approach to funding public interest journalism might be a levy funded by the platforms.
Pell-Lucas polynomials for numerical treatment of the nonlinear fractional-order Duffing equation
Authors: El-Sayed Adel Abd Elaziz
Published: June 2023

The nonlinear fractional-order cubic-quintic-heptic Duffing problem will be solved through a new numerical approximation technique. The suggested method is based on the Pell-Lucas polynomials’ operational matrix in the fractional and integer orders. The studied problem will be transformed into a nonlinear system of algebraic equations. The numerical expansion containing unknown coefficients will be obtained numerically via applying Newton’s iteration method to the claimed system. Convergence analysis and error estimates for the introduced process will be discussed. Numerical applications will be given to illustrate the applicability and accuracy of the proposed method.
Impacts of Brownian motion and fractional derivative on the solutions of the stochastic fractional Davey-Stewartson equations
Authors: Mohammed Wael W. , Al-Askar Farah M. , El-Morshedy Mahmoud
Published: June 2023

In this article, the stochastic fractional Davey-Stewartson equations (SFDSEs) that result from multiplicative Brownian motion in the Stratonovich sense are discussed. We use two different approaches, namely the Riccati-Bernoulli sub-ordinary differential equations and sine-cosine methods, to obtain novel elliptic, hyperbolic, trigonometric, and rational stochastic solutions. Due to the significance of the Davey-Stewartson equations in the theory of turbulence for plasma waves, the discovered solutions are useful in explaining a number of fascinating physical phenomena. Moreover, we illustrate how the fractional derivative and Brownian motion affect the exact solutions of the SFDSEs using MATLAB tools to plot our solutions and display a number of three-dimensional graphs. We demonstrate how the multiplicative Brownian motion stabilizes the SFDSE solutions at around zero.

Per una spiegazione causale delle differenze tra gli animali: Aristotele, Historia animalium I 1
Authors: Mingucci Giulia
Published: June 2023

It is now a widespread opinion among interpreters that Aristotle’s History of Animals is not a mere collection of empirical data but has its own theoretical framework; however, there is still disagreement as to exactly what this framework is. To address the problem, the article analyzes in detail the diairetic schemes of HA I 1, attempting to overturn the common opinion that this chapter is a mere expository introduction to the study of animals’ differences. On the contrary, it will be shown that in this chapter Aristotle not only applies the method of ‘multiple division’ theorized in Parts of Animals I 2–4, but also uses dividing criteria that are informed by his causal theory and his hylomorphist ontology. This analysis will therefore lead to the more controversial conclusion that HA is not an ‘early’ work by Aristotle but a mature treatise with its own specific theoretical aim: the aitiological explanation of the anatomical, eco-physiological and ethological differences among animals.
Une citation littérale de Mélissos dans le Sophiste de Platon
Authors: Cordero Nestor-Luis
Published: June 2023

Even if Plato never claimed to be a ‘historian of philosophy’, there are in his dialogues many references to previous philosophers. Apart from his works on the Sophists, which do not claim to faithfully expose the ‘philosophy’ of their authors, we find in Plato’s dialogues comments and sometimes quotations from the Presocratics, from Thales to Philolaos. In some cases, Plato adds the name of the quoted philosopher, but sometimes he leaves to the reader the task of finding out who the commented or quoted author is. This is the case with Melissos in a passage of the Sophist (244b), where his name is not quoted, but an anonymous monistic philosopher expounds a literal quotation of the philosopher: ἓν μόνον ἔστιν (fr. B 8.1 DK).

Published: June 2023

This paper is focused on evaluating the surface properties of protective coating prepared by plasma electrolytic oxidation on magnesium alloy EV31. Plasma electrolytic oxidation was performed in DC mode with a constant current density of 0.05 A cm−2 for 14 min. Evolution of voltage was measured and depicted graphically in order to describe the growth of the plasma electrolytic oxidation coating. Morphology and thickness of the plasma electrolytic oxidation coating were examined together with corrosion resistance of the coating by measurements of electrochemical characteristics using electrochemical impedance spectroscopy and potentiodynamic polarization after 1 h in 0.1 M NaCl. Results from potentiodynamic polarization showed decrease in corrosion current density i
corr from 10.50 μA cm−2 (substrate) to 1.02 μA cm−2 (plasma electrolytic oxidation coated) and results from electrochemical impedance spectroscopy showed increase in R
p by one order of magnitude for plasma electrolytic oxidation coated sample after both 1 h and 168 h exposure times.
An ecological psychology perspective in teaching Chinese online
Authors: Paul Jing , Nuesser Michaela , Zheng Dongping
Published: June 2023

In this paper, we first introduce three ecological principles for designing Chinese language online teaching and learning activities drawing from ecological psychology. The first principle – perception and action cycles in an ecosystem, advocates for situating online learning in a physical environment and creates activities with potentials to engage perception-action cycles. With the second principle – intention and attention merge in an ecosystem, we advocate for designing complex, flexible and dynamic activities and providing scaffolding for attunement. The third – meaning-making and values-realizing coincide in an ecosystem, calls for designing activities that allow for care-taking of oneself, each other, and the environment and cultivate curiosity and mindfulness for values-realizing and individual meaning-making. To highlight ways to tap into learners’ interest and connect to people and places, we then share two example activities with both low-technology and high-technology options.
From Nurturing the Successor to Attracting New Founders: How Firm Platforms Organize a Market for Selling Businesses
Authors: Stamm Isabell K.
Published: June 2023

Firm platforms organize a market for selling Mittelstand firms in Germany. In doing so they face a challenge: to instill a market frame in a segment of the German economy that is known for its family embedding. This study examines the strategies firm platforms use to reframe ownership transfer from a gift passed on within the family to a commodity traded on a market. Building on a content analysis of the seven largest and most innovative firm platforms in Germany, this study reveals how firm platforms argue from within a gift exchange frame and shift its parameters in social, object, and time dimensions. This study makes a more general point by arguing that digital platforms function as cultural trailblazers in marketization. This study contributes to succession, digital platform, and marketization debates.
Digital tildes (“∼”) may convey more: analyzing innovative uses of tildes in Chinese WeChat messages
Authors: Xu Huan , Xia Dengshan
Published: June 2023

Innovative uses of punctuation in online communication have become increasingly visible in research and public awareness since the 2000s, whereas studies on the innovative use of tildes (“∼”) in digital use remain scarce. Drawing on a data set of 543 Chinese WeChat messages with sentence-final tildes, this article investigates the uses and functions of innovative tildes in online communication using quantitative data and follow-up interviews. The findings suggest that: (1) The innovative tildes are deployed in messages implying sounds and performing speech acts in online communication, and they are more frequently used in speech acts (e.g., expressives and directives in particular). (2) The innovative tildes convey sound extension, i.e., to compensate for the loss of audio information in online communication and reproduce elongated sounds; pragmatic function, i.e., to enhance or mitigate the illocutionary forces of speech acts; and entertaining function, i.e., to make messages informal, vivid, joyful, and interesting. (3) The innovative tildes are pragmalicalized as a result of their semiotic features and politeness motivation of messengers for maintaining rapport and achieving successful online communication.
Dispersion engineering of infrared epsilon-near-zero modes by strong coupling to optical cavities
Authors: Johns Ben
Published: June 2023

Epsilon-near-zero (ENZ) materials have recently emerged as a promising platform for infrared nanophotonics. A significant challenge in the design of ENZ-based optics is to control the dispersion of ENZ modes that otherwise have a flat profile near the ENZ frequency. Strong coupling with an optical cavity is a promising approach to ENZ dispersion engineering, which however has limitations due to the lack of tunability or nanofabrication demands of the cavity employed. Here, we theoretically and numerically show that much of the limitations of previous approaches can be overcome by strongly coupling the ENZ mode to an unpatterned Fabry–Perot cavity. We demonstrate this unprecedented ENZ dispersion control in coupled cavities by designing tunable infrared polarizers that can absorb s and reflect p-polarized components, or vice versa, for almost any oblique angle of incidence, i.e. omnidirectional polarizers. The feasibility of active control is also demonstrated using a phase change material within the cavity, which predicts dynamic switchability of polariton dispersions across multiple resonant levels at mid-infrared wavelengths. These results are expected to advance the current understanding of strongly coupled ENZ interactions and demonstrate their potential in tailoring dispersions for active and passive control of light.
Controlling the physical field using the shape function technique
Authors: Trang ThanhTrung , Pham ThanhLong , Hu Yueming , Li Weiguang , Lin Shoujin
Published: June 2023

A field is described as a region under the influence of some physical force, such as electricity, magnetism, or heat. It is a continuous distribution in the space of continuous quantities. The characteristics of the field are that the values vary continuously between neighboring points. However, because of the continuous nature of the field, it is possible to approximate a physical field of interpolation operations to reduce the cost of sampling and simplify the calculation. This article introduces the modeling of the parametric intensity of physical fields in a general form based on the interpolation shape function technique. Besides the node points with sample data, there are interpolation points, whose accuracy depends significantly on the type of interpolation function and the number of node points sampled. Therefore, a comparative analysis of theoretical shape functions (TSFs) and experimental shape functions (ESFs) is carried out to choose a more suitable type of shape function when interpolating. Specifically, the temperature field is the quantity selected to apply, analyze, and conduct experiments. Theoretical computations, experiments, and comparisons of results have been obtained for each type of shape function in the same physical model under the same experimental conditions. The results show that ESF has an accuracy (error of 0.66%) much better than TSF (error of 10.34%). Moreover, the field model surveyed by a generalized reduced gradient algorithm allows for identifying points with the required parameter values presented in detail. The illustrated calculations on temperature field control in the article show that the solution for both forward and reverse problems can be determined very quickly with high accuracy and stability. Therefore, this technique is expected to be entirely feasible when applied to thermal control processes such as drying in paint technology, kilns, and heat dissipation in practice.
Interactive Dynamic Presentation (IDP) and Semantic Faceted Search and Browsing (SFB) of the Wittgenstein Nachlass
Authors: Pichler Alois
Published: June 2023

In 2000 the Wittgenstein Archives at the University of Bergen (WAB) published the CD-ROM edition of Wittgenstein’s Nachlass: The Bergen Electronic Edition (BEE). Moreover, since then WAB has worked towards complementing the static CD-ROM edition with an interactive web platform that additionally allows more user-specific and more user-tailored utilizations of WAB’s Nachlass resources. The paper describes two specific web service tools of this platform: Interactive Dynamic Presentation (IDP) of the Wittgenstein Nachlass and Semantic Faceted Search and Browsing (SFB) of Wittgenstein domain metadata. The paper argues that it is only when these two tools are fully implemented and functional that WAB can adequately serve the scholarly needs of the Wittgenstein Nachlass user community. The paper discusses some selected features and functionalities of the two tools in detail.

An earlier version of this paper was published as „Complementing Static Scholarly Editions with Dynamic Research Platforms: Interactive Dynamic Presentation (IDP) and Semantic Faceted Search and Browsing (SFB) for the Wittgenstein Nachlass“ in Selected Papers from the CLARIN Annual Conference 2020, ed. by C. Navarretta & M. Eskevich (Utrecht: CLARIN ERIC). In writing this paper I have benefitted from comments by K. De Smedt, N. Gangopadhyay, Ø. Gjesdal, J. Hendrickson, C. Huitfeldt, H. Al Ruweh, the Clarin 2020 conference reviewers and editors as well as Jasmin Trächtler.

Apresentação do critério imanente: Por uma crise da avaliação
Authors: Feil Gabriel Sausen
Published: June 2023

Este artigo quer pôr em crise o tema da avaliação por meio da concepção, de Roland Barthes, de que não há como avaliar sem colocar o objeto avaliado em crise. Abalizado em tal concepção, propõe o procedimento do critério imanente, que tem como característica o fato de ser inventado não antes da experiência avaliativa, mas durante. Analisa dois textos que problematizam a avaliação pressupondo critérios externos, e faz isso usando como estratégia metodológica a própria noção de critério imanente. Após a análise dos dois textos, conclui que a principal desvantagem do uso dos critérios externos está no fato de que em vez de colocar o objeto em crise, apenas coloca-o no desafio de se adaptar ao já esperado; e que o uso do critério imanente tem como atrativo os fatos de promover a criação de novos critérios a cada nova avaliação e o de afirmar a potência singular de cada texto.

Argumenta-se que os Grupos de Pesquisa estão fortemente incorporados na cultura de pesquisa, principalmente na Pós-Graduação e que, no Brasil e na América Latina, os Grupos de Pesquisa necessitam de maior valorização e reconhecimento no âmbito das instituições e dos órgãos de fomento.
O livro de literatura para crianças e jovens no universo digital: transformações, desafios e possibilidades
Authors: Kirchof Edgar Roberto
Published: June 2023

Este artigo apresenta, de forma panorâmica, algumas das principais transformações que as tecnologias digitais têm produzido sobre o livro, tomando como base o caso específico dos livros para crianças e adolescentes. O fundamento teórico das reflexões aqui propostas são os estudos sobre a história da escrita e da leitura realizados pelo historiador francês Roger Chartier. Com base nas teses de Chartier, argumenta-se, inicialmente, que as tecnologias digitais produzem mudanças sobre as três dimensões que definem a cultura do livro impresso, a saber, o texto, a materialidade e a autoria. Em seguida, é demonstrado como essas mudanças ocorrem no campo específico da literatura infantojuvenil.
“Prezadas professoras”: a temática da mulher na vida e obra de Paulo Freire
Authors: Andreola Balduino Antonio
Published: June 2023

A argumentação central do texto, ao discutir a condição da mulher desde a vida e a obra de Paulo Freire, é a de que não adianta querer mudar, de maneira artificial, burocrática e autoritária, a gramática porque não será essa atitude que mudará a realidade. No caso dos problemas de gênero, a discriminação, a dominação, a opressão da mulher, por parte do homem, numa cultura plurimilenar de machismo, a nossa luta precisa ser para mudar a realidade opressora. A língua, com sua gramática anacrônica e autoritária, também mudará. Essa foi a luta de Freire e está sendo de milhões de pessoas no mundo, que não o repetem, como ele nunca quis que fosse, mas o recriam, como ele propôs numa de suas últimas entrevistas: “Cabe a vocês inventarem novas pedagogias”.

Yaş tarhana ilavesi ürünlerin raf ömrü sürecinde doğal bir hidrokolloid ve antioksidan görevi yapmıştır. Ürünlerin hiç birinde 7 günlük raf ömrü sonucunda küf gelişimi gözlenmemiştir.
Toripalimab-associated diabetes mellitus: a case report from the community of Southern China
Authors: Zhang Wenxin , Xu Wenqiong
Published: June 2023

Immune checkpoint inhibitors (ICPis) are novel immunotherapy drugs for a variety of cancers. Toripalimab is one of the ICPis that selectively blocks programmed death 1 (PD-1) and has been used for the treatment of malignant cancers in the hospitals of China. But with the widespread use of ICPis, some of the adverse reactions have gradually appeared. One of the most serious side effects is diabetes mellitus which is a relatively rare immune-related adverse event (irAEs) with life-threatening complications. We report a case of diabetes after the administration of toripalimab for the treatment of melanoma in southern China. To our knowledge, this is a rare case of diabetes occurring during toripalimab therapy, there is only one similar case reported in China so far. As China has a high morbidity of malignant cancer, a significant number of patients could be affected by the adverse reactions of using ICPis. Therefore, when ICPis are administrated, it is very important for clinicians to pay attention to one of the serious side effects – diabetes mellitus. Insulin therapy is often necessary after the diagnosis of ICPis-related diabetes, which has been proved as an effective method to prevent diabetic ketoacidosis (DKA) and other life-threatening complications in these patients.

Learning points

Toripalimab can cause the diabetes mellitus.

ICPis-related diabetes is treated primarily with insulin.

Immune checkpoint inhibitors cause diabetes by primarily destroying islet β cells.

There is not enough evidence to demonstrate that diabetic autoantibodies are related to diabetes caused by ICPis.

In addition to focusing on the efficacy of PD-1 inhibitor therapy, it is also necessary to pay attention to its adverse reactions, such as ICPis-related diabetes mellitus.

Nuevas perspectivas, nuevas cartografías: de los Gay Studies a la teoría Queer / New Perspectives, New Cartographies: From Gay Studies to the Queer Theory
Authors: Mira Nouselles Alberto
Published: June 2023

Este texto repasa la confluencia entre trabajo teórico sobre género y estudios sobre cine. En concreto, estudia cómo los paradigmas sobre la homosexualidad afectan el modo en que podemos leer los textos fílmicos. Los paradigmas surgen de la necesidad de dar forma a la realidad y a la experiencia. En el caso de la homosexualidad, las primeras aproximaciones fueron científicas y, según el término de Sedgwick, «minorizadoras»: se aproximaban a la homosexualidad como algo que sólo afectaba a una minoría y que podía distinguirse claramente de la heterosexualidad. Esto tiene repercusiones en la representación durante el periodo clásico. Los estudiosos que se identificaban con este paradigma buscan evidencia de «el homosexual» como una especie. El modelo «gay» fue una respuesta minorizadora a propuestas que se consideraban como marginalizadoras. En términos de estudios cinematográficos, las aproximaciones a temas gays en España suelen asumir este paradigma. La segunda parte del texto describe cómo las intervenciones teóricas de Eve Kosofsky Sedgwick, Judith Butler y Teresa De Lauretis, con profundas raíces en la filosofía, la historia y el psicoanálisis, cambiaron percepciones sobre cómo leer «homosexualidad» en el cine, dando paso a las aproximaciones «queer».Palabras clave: gay, queer, homosexualidad, género, representación, crítica, académico, Sedgwick, Dyer, Butler.AbstractThis text outlines the confluences between theoretical work on gender and film studies. More specifically, it addresses the way paradigms on homosexuality have affected what we can read into the film text. Paradigms arise from the need to shape reality and experience. In the case of homosexuality, early approaches were scientific and what Sedgwick calls «minoritizing»: they attempted to deal with homosexuality as something affecting only a minority and as something very clearly distinguishable from heterosexuality. This has consequences in representation on screen during the classic period. Film academics who place themselves in this paradigm find actual evidence of «the homosexual». The «gay» model was the minoritizing response to proposals considered as marginalizing. In terms of film studies most of the approaches to gay issues in Spain still assume this paradigm. The second part of the text deals on how theoretical interventions from the early nineties by Eve Kosofsky Sedgwick, Judith Butler and Teresa De Lauretis, with strong roots in philosophy, psychoanalysis and history, changed perceptions on how to read «homosexuality» in film, giving rise to «queer» approaches.Keywords: gay, queer, homosexuality, gender, representation, criticism, academia, Sedgwick, Dyer, Butler.

La política expansionista del cine argentino y, desde 1942, razones de supervivencia ante el acoso de Hollywood empujan a la Asociación de Productores de Películas Argentinas (APPA) a presionar al gobierno español para que firme un acuerdo cinematográfico. Este se rubrica en1948, tras casi diez años de tensas negociaciones. Pero los artículos del acuerdo, más que responder a los deseos de la APPA, reflejan los intereses y la hermandad alcanzada por el franquismo y el peronismo.Palabras clave: España, Argentina, comercio cinematográfico, Asociación de Productores de Películas Argentinas.AbstractThe expansionist policy of Argentine cinema and the power of Hollywood's entertainment industry since 1942, push the Argentinean Film Producers Association (APPA) to put pressure on the Spanish government to sign a film agreement. This was signed in 1948, after almost ten years of tense negotiations. However, the articles of the agreement, rather than responding to the wishes of the APPA, reflect the treaty of friendship between the Franco regime and the Peronism.Keywords: Spain, Argentina, Movie Trade, Argentinean Film Producers Association.
Mímesis y recepción del cine de Bollywood en el ámbito audiovisual occidental: entre la ironía orientalista y el compromiso transnacional / Mimesis and Reception of the Bollywood Cinema in the Western Audiovisual Field. Between Orientalist Irony and Transnational Commitment
Authors: Roncero Israel
Published: June 2023

El presente texto trata de analizar las influencias recíprocas del panorama audiovisual occidental y el cine de Bollywood, contextos culturales que se contaminan mutuamente, pero que dada la asimetría de las diferentes categorías geopolíticas a las que se adscriben, precisan de un análisis crítico que ayude a determinar las consecuencias políticas de la imitación de un cine periférico por parte de un cine legitimado globalmente. Para ello, una vez dibujado el panorama medial y cultural de este diálogo cinematográfico, pasaremos a ejemplificar los efectos de la mímesis occidental de los productos del cine de la India con el estudio de un caso particular. Este análisis pormenorizado nos permitirá establecer dos hipótesis interpretativas diferenciadas, que intentarán determinar si la mímesis occidental del cine de Bollywood es una apropiación irónica que trata de restar el valor del producto citado o, por el contrario, un producto híbrido transnacional con una vocación dialógica.Palabras clave: Bollywood, mímesis iconográfica, orientalismo postmoderno, hipertextualidad, ironía, transnacionalismo, empoderamiento del sujeto subalterno.AbstractThis paper analyzes the interplay of both Western audiovisual landscape and Bollywood cinema, cultural contexts that are constantly polluting each other, but due to the asymmetry of the different political categories of origin, a critical analysis that helped us to determine what the political consequences are when a peripheral cinema imitates a globally entitled cinema would be required. To achieve this, once drawn the media and cultural landscape of this cinematic dialogue, we will illustrate the effects of Western mimesis of India products with the study of a particular case. This detailed analysis will allow us to establish two distinct interpretative hypotheses that will attempt to determine whether Western mimesis of Bollywood cinema is an ironic appropriation that subtracts the value of the cited product or, conversely, a hybrid product with the vocation of achieving a transnational dialogue.Keywords: Bollywood, iconographic mimesis, postmodern orientalism, hypertext, irony, transnationalism, empowerment of the subaltern subject.

El espejo televisivo de Claude. Estética, ciencia y ficción en Black Mirror / Claude’s Television Mirror. Aesthetic, Science and Fiction in Black Mirror
Authors: García Pousa Laura
Published: June 2023

A través del estudio de la primera temporada de la serie televisiva Black Mirror (Charlie Brooker/ Zeppotron, 2011-) exploramos una tipología de ficción contemporánea que, desde su particular e identificable definición británica, crece en modos y se expande convirtiéndose en un nuevo referente de creación audiovisual internacional. Asimilados los límites dramáticos y estéticos de la era del drama y de la post-televisión, y superada la vinculación cine / videoarte, televisión / publicidad, Black Mirror adopta una perspectiva cultural del progreso científico y tecnológico que determina su drama. El análisis específico de sus tres dispares capítulos –«TheNational Anthem», «Fifteen Million Merits» y «The Entire History of You»– nos llevará por un camino comparativo con el objetivo de identificar su valor narrativo y su aportación artística, desde una metafórica vinculación conceptual con el espejo oscuro y el clasicismo pictórico de Claude Lorrain.Palabras clave: Black Mirror, ciencia, ficción, drama, televisión, pantallas, realidad virtual, futuro, «The National Anthem», «Fifteen Million Merits», «The Entire History of You».AbstractThrough the study of the first season of the TV series Black Mirror (Charlie Brooker / Zeppotron,2011-) we explore a typology of contemporary fiction that develops from its particular and identifiably British definition into a new referent for international audiovisual creations. Assuming both the dramatic and aesthetic boundaries of the era of drama and of post-television, and the established connections between film / video-art, television / publicity, the plot of Black Mirror is determined by its adoption of a culturally-specific perspective on scientific and technological progress. Beginning with a metaphorical conceptual link to the [notion of the]dark mirror and the pictorial classicism of Claude Lorrain, this comparative analysis of its three disparate episodes—«The National Anthem», «Fifteen Million Merits» and «The Entire History of You»— aims to identify the narrative value and artistic contribution of the series.Keywords: Black Mirror, science, fiction, drama, television, screens, virtual reality, future, «The National Anthem», «Fifteen Million Merits», «The Entire History of You».

Published: June 2023

Effects of enzyme pretreatment on the properties of fast-growing poplar APMP pulp were evaluated. Compared with the unpretreated pulp, the beatabilities of the pulp that had been pretreated by enzymes were improved significantly, such as a decrease of Canadian Standard Freeness (CSF) in the range of 25 mL to 55 mL, a decrease of PFI mill revolutions from 1000r to 5500r, and a decrease of beating energy consumption from 12.5% to 22.0%. The values of brightness, breaking length, tearing index, bursting index, and folding number of the pulp pretreated by cellulase were improved by 1.2%ISO, 23.7%, 14.8%, 14.6%, and 50% respectively, while that of the pulp pretreated by xylanase were respectively improved by 2.1%ISO, 16.8%, 8.8%, 8.9%, and 25%. The optimal enzyme dosages were 25 IU•g-1 and 25IU•g-1 for cellulase and xylanase, respectively. Fibre quality analysis results showed that the fibre length of pretreated pulp increased partly, fibre width and fines content decreased, fibres torsion increased, and fibre bonding got stronger. X-ray diffractometer analysis indicated that the degree of crystallinity of fibres increased after the enzyme pretreatment.

The present paper aims to investigate the physical characteristics of sawdust relative to its use as an adsorbent for removal of an acid dye (Orange G) from aqueous solutions. The raw sawdust was sieved to have a uniform size and was activated by sulphuric acid by refluxing the content at 60 oC for 4 h. Surface morphology and surface functional groups of both raw and modified sawdust samples were investigated by Scanning Electron Microscope (SEM), Energy Dispersive X-ray Analysis (EDX), Fourier Transformation Infrared (FTIR), and elemental analysis. All these analyses displayed significant change in the structure of the sawdust. The data obtained from batch adsorption experiments for the removal of the selected dye confirmed that adsorption characteristics of the modified sawdust were better than those of raw sawdust.

Continuous process improvement and automation have proven to be powerful tools for the wood processing industries in order to obtain better final product quality and thus increase profits. Abrasive machining represents an important and relevant process in the manufacturing and processing of wood products, which also implies high cost of materials and labor; therefore, special attention to this process is necessary. The objective of this work was to evaluate and demonstrate a process control system for use in the abrasive machining of wood and wood-based products. A control system was created on LabView® to integrate the monitoring process and the actions required, depending on the abrasive machining process conditions. The system acquires information from the optical sensor to detect loading and activate the cleaning system. The system continuously monitors the condition of the abrasive belt (tool wear) by using an acoustic emission sensor and alerts the operator of the status of the belt (green, yellow, and red lights indicating satisfactory, medium, and poor belt condition). The system also incorporates an additional safety device, which helps prevent permanent damage to the belt, equipment, or workpiece by alerting the operator when an excessive temperature has been reached. The process control system proved that automation permits enhancement in the consistency of the belt cleaning technique by the elimination of the human errors. Furthermore, this improvement also affects the cost by extending the life of the belt, which reduces setup time, belt cost, operation cost, as well as others.
The effect of kenaf fibre loading on curing characterisitics and mechanical properties of waste tyre dust/kenaf fibre hybrid filler filled natural rubber compounds
Authors: Ismail Hanafi , Omar Nurul Farhana , Othman Nadras
Published: June 2023

Waste tyre dust (WTD)/kenaf fibre (Ke) hybrid filler filled natural rubber (NR) compounds having constant 30 phr loading were prepared with increasing partial replacement of WTD by kenaf fibre at 0, 10, 15, 20, and 30 phr. Curing characteristics, mechanical properties, rubber-fibre interaction, and morphology of the NR compounds were studied after the compounds were obtained. The curing characteristics such as t2 and t90 increased with increment of kenaf fibre loading. For MHR, the increasing partial replacement of WTD by kenaf fibre showed increasing MHR value. For tensile properties, the value of tensile strength and elongation at break value decreased with increasing kenaf fibre loading. The values of M100 and M300 increased but then decreased after the addition of 15 phr of kenaf fibre loading. Besides, fatigue life value also showed a decreasing trend with increasing kenaf fibre loading. For rubber-fibre interaction, the values of Qf/Qg showed a small increment with increasing kenaf fibre loading. The SEM micrographs obtained for fractured surface of WTD/kenaf fibre hybrid filled NR compounds supported the results for the mechanical properties.
