Does the teaching-learning model based on the flipped classroom improve academic results of students at different educational levels?
Authors: González-Velasco Carmen , Feito-Ruiz Isabel , González-Fernández Marcos , Álvarez-Arenal José-Luis , Sarmiento-Alonso Nicolás
Published: January 2021

The teaching-learning model that still predominates in higher education is the traditional one, based on the master class taught by the teacher. However, it is necessary to resort to other models of teaching and learning that are more flexible and active for students. For this reason, the main objective of this paper is to apply the flipped classroom teaching-learning model in order to test and compare if the academic results of students with the flipped classroom model improve with respect to the traditional model at different educational levels. In addition, the students' assessment of this teaching-learning model and the use of Information and Communication Technologies is analyzed. This study presents the experience of teaching innovation based on the inverted class model, which has been carried out with 155 students belonging to different educational levels and with six subjects related to the Financial Economics discipline. For this, a descriptive statistical analysis is performed, as well as analysis of contingency tables to detect the degree of association between the educational level and the teaching-learning model applied for the evaluation of the students. Evidence is obtained that university students obtain better academic results with the traditional model, while non-university students achieve better grades with the flipped classroom model. However, the students' assessment of the flipped classroom model has been very positive, regardless of educational level. The results suggest that the flipped classroom model improves the academic results of non-university students because they are more accustomed to the application of new technologies than university students.
La elección de centro educativo en un sistema de cuasi-mercado escolar mediado por el programa de bilingüismo
Authors: Murillo F. Javier , Almazán Adrián , Martínez Garrido Cynthia
Published: January 2021

Introducción. Esta investigación busca comprender las razones que orientan la elección de centro por parte de las familias cuyas hijas e hijos estudian en centros públicos de la Comunidad de Madrid, haciendo especial énfasis en conocer el papel que juegan los centros bilingües en las problemáticas generales asociadas a la elección de escuela. Método. Para dar respuesta a este objetivo se realiza una investigación cualitativa basada en entrevistas semiestructuradas a 14 representantes de diferentes Asociaciones de Madres y Padres de Alumnos/as tanto de Colegios Públicos de Educación Infantil y Primaria como de Institutos de Secundaria, la mitad de ellos bilingües y la otra mitad no, todos ellos del municipio de Getafe. Resultados. La adscripción o no del centro al programa bilingüe ha alterado radicalmente los criterios de selección de centro por parte de las familias en estos últimos años. De esta forma, la cercanía al centro y la percepción social de la calidad del centro son los factores más importantes de elección. En el caso de la pertenencia al programa bilingüe supone tantas críticas como adhesiones, existiendo fuerte rechazo por las familias en muchos casos por la segregación que está generando. Discusión. El Programa Bilingüe y la aparición del distrito escolar único está generando una fuerte polarización de la sociedad que intensifica la segregación del sistema educativo. Parece, por tanto, necesario replantearse las medidas de libre elección y afrontar una evaluación global e independiente del programa de bilingüismo.

Authors: Saini Noor Shazreen Amalin , Rosli Roslinda
Published: January 2021

Financial literacy is one of the 21st-century skills that are important for young people. Thus, integrating financial components in Mathematics subject is a way to instill financial literacy among students. This study aimed to determine the factor influencing the integration of financial elements and identify effective methods to enhance studentsʹ financial literacy. The research articles are collected from 2011 until 2019 through online databases known as Education Resources Information Center (ERIC), Sage Journals, Web of Science (WOS), ScienceDirect, and SCOPUS. The research finding shows that the factors affecting studentsʹ financial literacy were teaching methods and strategies, parental socialization, and school curriculum. It is essential to understand the influence of numerous factors. Knowing the factors that lead to or detract from the acquisition of financial literacy among students will improve their economic well-being by making policy initiatives. Financial socialization such as learning in school and parentsʹ involvement has become a significant factor in studentsʹ financial literacy. The practical methods used to enhance studentsʹ financial literacy consist of inquiry-based mathematics, technological simulation, interactive module, simulation games, workshops, and school camps.
Between History and Prophecy: Ovidian Metamorphoses and the 1381 Revolt in Gower's Visio Anglie
Authors: Ni Yun
Published: January 2021

Ovid's narratives of metamorphosis offer a repertoire of individual and collective changes that enabled John Gower to account for the 1381 revolt in Visio Anglie. Most of the scholarship on the Visio has discussed the poet's traditionalism. The traditionalism of the rebels, in contrast, has been well documented by historians but is often ignored by literary scholars. This paper explores the ideological symbiosis between the traditionalism of the poet and that of the rebels. Through close readings of Ovidian allusions in Visio, this article argues that Gower's archaized Ovidian voices, unlike the peasants' romanticization of the past, affirm a belief in historical flexibility. Gower adapts Ovid to highlight historical perspectives that reverse monstrosities, thereby acknowledging collective guilt. Through textual overlays, he also combines the Edenic and the apocalyptic—the two ends of history—to reveal that there is no static idealized past to which to return.
“Semy-vif for sorow”: Disability and Tragedy in Troilus and Criseyde and the Tale of Beryn
Authors: Chace Jessica
Published: January 2021

Much has been said about Troilus's lovesickness in Chaucer's Troilus and Criseyde, but few have considered Troilus's medical condition to be a disability in the modern sense—that is, a physical and/or mental difference that is also socially constructed. Because the term “disability” is itself anachronistic, this article turns first to another text about a disabled tragic hero, the anonymous fifteenth-century poem Tale of Beryn, because it both draws on Chaucerian influences and offers useful terminology. It argues that the Beryn writer's description of Beryn as “semy-vif for sorow” is eminently applicable to Troilus because it describes a psychosomatic condition as much as it captures the physical, psychological, and social liminality of the medieval disabled. The term helps to clarify a number of instances in Troilus and Criseyde in which Chaucer uses disability imagery or metaphor to convey the tragic circumstances of his hero—the most notable example being Chaucer's description of Troilus's limp in Book V to convey his hero's despair at the loss of Criseyde. This article suggests that Chaucer's poem anticipates the personal tragedy model of disability of the modern era, in which some in the nondisabled community view people with disabilities as tragic figures burdened by fate rather than as individuals with natural mental or bodily variations.
Dom John Broadhook alias John Lydgate, 1424
Authors: Sobecki Sebastian
Published: January 2021

In a note published in this journal in 2019, Sebastian Sobecki drew attention to a new life-record for John Lydgate. The document, which dates to late January or early February 1425, is of significance because it offers the earliest surviving record of Lydgate's tenure as prior of Hatfield Regis. However, the record only refers to him as “John, prior of Hatfield Regis.” Here the author would like to present three new life-records from 1424, all of which mention Lydgate by name and identify him as prior of Hatfield Regis, therefore pushing back the evidence for his time as prior by a calendar year.
Racism and “Self-Love”: The Case of White Nationalism
Authors: Monahan Michael J.
Published: January 2021

The rise in the public profile of “alt-right” and “white nationalist” groups in recent years is often described as a rise in “hate groups.” The presumption in this nomenclature is that these sorts of groups are defined essentially in terms of their shared hatred for some or all nonwhite individuals and groups. However, the rhetoric of such groups is couched not as hatred, but rather in terms of “self-love”—they do not hate other groups, they are just looking out for themselves. The author's argument in this article is that, even if we assume the sincerity of white nationalists' claims to be only interested in sustaining and defending whites and whiteness, the kind of “self-love” this exhibits is morally and politically pernicious precisely because it is constitutively linked to a foundational contempt for nonwhites.
On “Ur-Contempt” and the Maintenance of Racial Injustice: A Response to Monahan's “Racism and ‘Self-Love’: The Case of White Nationalism”
Authors: Silva Grant J.
Published: January 2021

This article offers a response to Michael J. Monahan's engagement with and criticism of Grant Silva's article “Racism as Self-Love.” So as to demonstrate how Monahan's idea of “ur-contempt” fits alongside the author's project and supplements his attempt to challenge the variety of forms of moral obfuscation employed by white nationalists and other racists today, this response begins with an overview of the central critique of moral responsibility for racism that Silva's work offers. At stake is the attempt, by unabashed white supremacist and others, to bank on historical acts of racial oppression and reap the benefits of elevated social status while evading responsibility for that past. The goal in this project is thus to demonstrate the entanglement of interpersonal and structural forms of racism while also describing how racism unfolds in the present in order to challenge the types of moral evasion for racism that Monahan and Silva are concerned with.
Politicizing the Geological: Articulations of Earth and History in Modern Philosophical Race Discourse
Authors: Lettow Susanne
Published: January 2021

Against the backdrop of the current “geological turn,” the article sheds light on the ways in which the earth has been articulated through strategies of temporalization and territorialization in the context of modern philosophical race discourse. The author first reconstructs the constitution of a “geographic imagination” as it emerged in the late eighteenth and early nineteenth centuries. The first part focuses on the role of geography in Kant's theory of race, and Alexander von Humboldt's project of plant geography. In the second part, the author discusses Henrik Steffens's account of race. In the third part, the author turns to Heidegger, who rearticulated the “geographic imagination” in the first decades of the twentieth century. The article concludes that a critical theory of nature relations needs to overcome the semantic connections between conceptualizations of the earth and the modern race discourse that haunt contemporary ecological thinking
What's the Matter with Value?: Anna Julia Cooper's Political-Economic Thought
Authors: Wolflink Alena
Published: January 2021

This article proceeds from a perspective on value and valuation that is distinct from moral and economic discourses of value in that it conceives of value as primarily, and even paradigmatically, political. Drawing from the insights of Anna Julia Cooper's political-economic writings, this article argues that value and values, markets and morals, and the constellation of issues entangled in modern discourses of valuation all have the effect of devaluing black life. It explores the tensions between economics and moral sentiments, as Cooper depicts them in her discussion of the concepts of worth and material. Cooper demonstrates the concept of matter to rely upon a tension between material goods and the common good. Cooper's discussion is therefore pivotal to understanding how political priorities mesh with systems of material interdependence.

Objective: To determine the effect of an innovative, online-based intervention, addressing the possible decline of physical activity (PA) and increase of sedentary behavior (SB) during COVID-19 stay at home restrictions in Switzerland.Methods: This study investigated the effect of a two-week, social cognitive theory based, online-video moderate to vigorous (MV)PA or SB intervention on MVPA and SB behaviour and intention via a 3 group by 2 time point parallel randomized controlled trial during the COVID-19 pandemic. Adults (≥18 yo) were recruited over the internet between April 10th and April 19th 2020 (n = 129; 75.2% female; mean age = 29.0 [SD 11.8] years). Both intervention groups received five videos targeting either SB for the SB group or MVPA for the MVPA group and were compared to an attention control group (fruit and vegetable consumption). It was hypothesized that MVPA time and intention would increase for the MVPA group and the SB group would outperform control on SB behaviour and intention indicators.Results: No significant interactions were found for the MVPA group (n = 41) versus control (n = 40). Only one significant interaction was measured for the SB group (n = 48; intention of active breaks F = (2,114) = 5.84, p = 0.004, ηp2 = 0.09). Although mostly non-significant and small effects, the MVPA group showed results pointing in the hypothesized direction on all PA indicators and the SB on all SB indicators, respectively.Conclusion: Considering this study’s limitations (e.g. small intervention dose), video-based online PA and SB interventions seem promising and feasible. This approach is appropriate for COVID-19 and other stay at home situations.
Ciencias naturales y aprendizaje socioemocional: una experiencia desde la enseñanza de las ciencias basada en la indagación
Authors: Molina-Ruiz Nancy , González-García Pía
Published: January 2021

La indagación científica es un concepto ampliamente usado en el ámbito escolar los últimos años, especialmente en el área de las ciencias naturales. En Chile, esta metodología ha sido implementada desde el año 2003 por el programa Enseñanza de la Ciencia Basada en la Indagación, ECBI Chile, y considera un ciclo indagatorio de 4 fases: focalización, exploración, reflexión y aplicación. El presente artículo expone los resultados de una investigación cuyo objetivo fue analizar las percepciones de estudiantes de educación básica respecto de su experiencia de trabajo con secuencias de aprendizaje basadas en la metodología de indagación científica. El estudio, de carácter cualitativo y con enfoque descriptivo-interpretativo, se realizó a través de la construcción de 5 categorías: estrategias concretas, clases no tradicionales, emociones, contextualización de la aplicación y utilidad. El análisis puso en evidencia que el uso de estrategias de indagación, en lugar de aquellas utilizadas tradicionalmente, modifica la visión de los/as estudiantes sobre las clases de Ciencias Naturales y su significado para la vida, demostrando sus preferencias ante aprendizajes vivenciales, en donde pueden expresar sus sentimientos y emociones libremente.

Educación virtual y enseñanza remota de emergencia en el contexto de la educación superior técnico-profesional: posibilidades y barreras
Authors: Ruz-Fuenzalida Carlos
Published: January 2021

Las nuevas tecnologías y los alcances de la revolución digital no solo han permeado la educación escolar con herramientas y medios innovadores para la mejora de la enseñanza y aprendizaje de los/as estudiantes, sino que también se han constituido en un recurso de trabajo cada vez más relevante en la educación superior. La educación superior técnico-profesional representa un porcentaje importante de la matrícula del segmento terciario y tiene características particulares y de contexto que la diferencian sustancialmente de la educación universitaria. Teniendo lo anterior en consideración y en el marco de la pandemia por COVID-19, este artículo se refiere a la necesidad que enfrenta la educación superior técnico-profesional de implementar urgentemente formas de trabajo a distancia, lo que, a su vez, requiere buscar nuevas estrategias, caminos y enfoques que tengan en cuenta el uso de las diferentes herramientas de virtualidad que existen hoy en día.
Formación docente en TIC y su evidencia en tiempos de COVID-19
Authors: Castillo-Retamal Franklin
Published: January 2021

La investigación que expone el presente artículo ha emergido de la necesidad de saber qué tan preparados están los/as profesores/as en el área de TIC para enfrentar sus labores educativas en tiempos de confinamiento, teniendo como objetivo conocer el nivel de dominio y uso de TIC de los/as profesores/as en tiempos de COVID-19. La metodología utilizada responde a una investigación cuantitativa no experimental de tipo transversal y de alcance exploratorio. La población de estudio está compuesta por 148 docentes de cuatro establecimientos educacionales y la muestra, no probabilística por conveniencia, corresponde a 66 individuos. Los resultados indican que el 78% de los/as encuestados/as usaba TIC antes de la situación de confinamiento, el 30% de la muestra no tuvo capacitaciones en esa área y solo el 36% se siente realmente preparado para formar a sus estudiantes a través de TIC. Se concluye que no existe una falta de conocimiento significativa con respecto al manejo y uso de TIC en el contexto educativo en tiempos de COVID-19, sin embargo, los/as docentes consideran que es un problema utilizar TIC en el contexto educativo, debido a que el confinamiento y la no presencialidad generan una retroalimentación más lenta entre estudiantes y profesores/as, en comparación a la que se produce en las condiciones educacionales normales.
Patella Fractures: Approach to Treatment
Authors: Hargett Damayea I. , Sanderson Brent R. , Little Milton T.M.
Published: January 2021

Patellar fracture morphology varies based on the mechanism of injury. Most fractures are either a result of direct impact or through an indirect eccentric extensor contraction injury. Each fracture pattern requires appropriate preoperative planning and individualization of the fixation method. Displaced fractures affect the extension apparatus, and often require surgical fixation. Surgical treatment is recommended in fractures with any of the following features: articular step-off > 2 mm, > 3 mm of fracture displacement, open fractures, and displaced fractures affecting the extensor mechanism. Meticulous handling of the soft-tissue envelope is of the utmost importance, given the patella's tenuous blood supply and limited soft-tissue envelope. Incongruent articular surface can result in detrimental long-term effects; therefore, surgical treatment is directed toward anatomic reduction and fixation. The evolution of patellar fracture fixation continues to maximize options to balance rigid fixation with low-profile fixation constructs. Improving functional outcomes, minimizing soft-tissue irritation, and limiting postoperative complications are possible by using the therapeutic principles of rigid anatomical fixation and meticulous soft-tissue handling.
The New Zealand strong motion earthquake recorder network
Authors: Hefford R. T. , Randal P. M. , Skinner R. I. , Beck J. L. , Tyler R. C.
Published: January 2021

The network of strong-motion earthquake recorders, maintained throughout New Zealand by the Engineering Seismology Section of the Department of Scientific and Industrial Research, is described. The instruments are either deployed as ground instruments to measure potential earthquake attack on structures, or in structures, e.g. buildings, dams and industrial installations, to record structural response. Details are given of installation of instruments, maintenance, laboratory work, record retrieval and digitisation, costs and staffing for the network. Future developments mooted include an improved digitising system, the introduction of an improved version of the existing mechanical-optical instrument in 1979, and, in the long term, the introduction of an entirely new digital recorder, having an electrical output from its accelerometers, which will make possible the transmission of data by telephone or radio link.
Suggested extensions of the New Zealand strong motion accelerograph network
Authors: Berrill J. B.
Published: January 2021

The principal aim of the present network of strong motion accelerographs is to record the response of structures to earthquakes, and instruments are concentrated in the larger cities where modern, tall buildings are found. However, the behaviour of structures during earthquakes is now comparatively well understood. At the present time, estimating design ground motions is the weakest part in the process of designing structures to resist earthquakes. There is a strong need for more recordings of ground shaking, particularly sets of several accelerograms from single earthquakes. It is not certain that the present accelerograph network would capture any significant record of strong motion during a major earthquake in New Zealand; and the chance of a set of three or more strong accelerograms being recorded is quite small. It is recommended that 25 additional instruments be installed promptly, to fill the main gaps in the present network, and to extend the capacity of the existing local network in the Wellington area.
The Impact of Celebrity Endorsement on Brand Loyalty: Mediating and Moderating Mechanisms
Authors: Burnasheva Regina , Suh Yong Gu
Published: January 2021

Applying the meaning transfer theory, the purpose of this study is to proffer a theoretical framework in which celebrity endorser’s credibility (CEC) effects the brand loyalty through the mediating role of brand relationship quality and the moderating role of the celebrity-brand congruence. Data was gathered through an online survey from young Korean millennials and tested using structural equation modeling and multi-group techniques. The findings revealed that brand relationship quality serves as a partial mediator of the effect of CEC on brand loyalty. The findings also suggested that celebrity-brand congruence acts as a moderator between CEC and the brand relationship quality. This study offers useful practical implications for luxury marketers and advertisers.
Target Social Media Presence and Its Effects on Acquirers’ Decision
Authors: Ravaonorohanta Nivo , Refakar Mohammad
Published: January 2021

Our objective is to determine whether firms’ presence on social media improves the decision-making process in mergers and acquisitions (M&As), and thus the quality and performance of the transaction. Based on a sample of 309 domestic mergers carried out by Canadian companies between 2012 and 2016, the empirical evidence strongly supports our hypothesis as we find that the active presence of target firms on social media enhances the likelihood of M&A completion. In addition, M&As carried out by firms active on social media are also more likely to create value. These findings suggest that information posted on social media helps firms identify the best partnerships, i.e., those target firms with which the acquiring firms will be able to work in synergy.
A Feasible Approach to Determine the Optimal Relaxation Parameters in Each Iteration for the SOR Method
Authors: Liu Chein-Shan
Published: January 2021

The paper presents a dynamic and feasible approach to the successive over-relaxation (SOR) method for solving large scale linear system through iteration. Based on the maximal orthogonal projection technique, the optimal relaxation parameter is obtained by minimizing a derived merit function in terms of right-hand side vector, the coefficient matrix and the previous step values of unknown variables. At each iterative step, we can quickly determine the optimal relaxation value in a preferred interval. When the theoretical optimal value is hard to be achieved, the new method provides an alternative choice of the relaxation parameter at each iteration. Numerical examples confirm that the dynamic optimal successive over-relaxation (DOSOR) method outperforms the classical SOR method.

Published: January 2021

Diljem svijeta vjerske zajednice i laička vjerski orijentirana udruženja potiču vjernike, osobito mlade, na aktivan angažman u promicanju i zaštiti religijskih vrijednosti. U Hrvatskoj se vjerski društveni angažman promovira i prakticira već desetljećima, no taj je iskaz religioznosti ostao posve neistraženim. U svrhu stvaranja pretpostavki za izučavanje raširenosti, oblika, pozadine i učinaka takve vjerske prakse, u radu se predstavlja izrada i metrijska provjera Skale vjerom inspiriranoga društvenog angažmana (VIDA). U kvalitativnome dijelu istraživanja kreirano je 16 indikatora konceptualno predviđenih dimenzija humanitarnoga, evangelizacijskog, građanskog i političkoga društvenog angažmana. Anketni, evaluacijski, dio istraživanja proveden je na slučajnom uzorku mladih u dobi od 18 do 25 godina (N = 552), selektiranih iz velikoga nacionalnog internetskog panela. Struktura i spolna invarijatnost VIDA-e provjerena je konfirmacijskom faktorskom analizom, a valjanost njezinim povezivanjem s drugim mjerama religioznosti te srodnim stavovskim i vrijednosnim obilježjima. Za cjelinu i podskale VIDA-e analizama je demonstrirana kriterijska, konstruktna i diskriminacijska valjanost, visoka interna konzistentnost, dobro pristajanje latentne strukture podacima te podjednaka primjenjivost na mlade muškarce i žene u Hrvatskoj. Na kraju rada kratko se raspravlja o ograničenjima i mogućnostima uporabe nove mjere.

Ambiente institucional e empreendedorismo no Brasil: inter-relações no século XXI
Authors: Corsino Michelle Oliveirado Espírito Santo , Mariani Milton Augusto Pasquotto
Published: January 2021

Partindo dos pressupostos balizados pela Nova Economia Institucional acerca das instituições e do ambiente institucional e dos dados coletados pela pesquisa Global Entrepreneurship Monitor (GEM), nos anos 2000 e 2017, o presente ensaio teórico objetiva apresentar evidências das inter-relações existentes entre o ambiente institucional e o empreendedorismo no Brasil. Dessa forma, utilizando-se de uma abordagem qualitativa, são apresentados alguns elementos do ambiente institucional brasileiro que têm favorecido o empreendedorismo e outros que têm limitado a criação e manutenção de novos empreendimentos no país, no século XXI. Nesta perspectiva, a partir da lente da teoria institucional e da teoria do empreendedorismo, o presente estudo teórico demonstra o papel das instituições enquanto “regras do jogo” (políticas, sociais e legais) que influenciam diretamente na evolução do fenômeno do empreendedorismo, bem como proporciona uma reflexão no que tange ao ambiente institucional brasileiro, demonstrando até que ponto ele promove um cenário propício à iniciativa econômica de criar empreendimentos.
Análise dos fundos de investimento brasileiros através do CAPM cointegrado com regimes de Markov
Authors: Milani Bruno , Ceretta Paulo Sérgio
Published: January 2021

O tradicional modelo CAPM já foi largamente utilizado para analisar a relação entre retornos de fundos de investimento e retornos de mercados. Este artigo analisa a relação entre o retorno de fundos de ações brasileiros e o retorno do Ibovespa, trabalhando com um modelo análogo ao CAPM, estimado por meio de Cointegração de Séries temporais. A análise é enriquecida estimando mudanças de regimes de Markov. Os resultados apontam que há regimes muito bem delineados, tanto no curto quanto no longo prazo, sendo que a dependência dos preços dos fundos em relação aos preços do mercado é maior no período de alta e menor no período intermediário. No curto prazo, o retorno dos fundos depende menos do retorno dos mercados quando o mercado apresenta baixa volatilidade e mais quando o mercado apresenta volatilidade média.

Este artigo trata do valor da informação em um projeto de exploração e produção de gás natural. A análise financeira de campos de gás natural é parte fundamental na tomada de decisão de investimentos por parte das empresas do setor, governo e agentes do mercado financeiro. Uma análise eficaz pode poupar recursos econômicos importantes ou mesmo gerá-los quando tudo indicar o contrário. Durante as etapas do projeto de exploração e produção, o concessionário faz elevados investimentos em aquisições de dados geológicos, os quais aumentam o nível de conhecimento do ativo em questão. Este estudo de caso analisa esta questão à luz da Teoria das Opções Reais, utilizando o método de inversão bayesiana para quantificar o valor da informação, explorando opções de abandono e de expansão do projeto. A relevância do presente artigo consiste na apresentação de um modelo de avaliação aplicado num segmento de altíssima importância para a economia brasileira.
A pantomima de Regina: fragmento simbólico integrado à rede interdiscursiva de reciclagem memorialística
Authors: Costa Daiman Oliveira da
Published: January 2021

Este artigo se propõe a analisar um pontual acontecimento discursivo presente na entrevista de Regina Duarte, ex-secretária especial de cultura do governo brasileiro, para a emissora de televisão CNN Brasil, em 7 de maio de 2020. Mais especificamente, defende-se a hipótese de que a marchinha “Pra frente, Brasil”, cantada por Regina durante a entrevista, funcionou como um acontecimento discursivo sutilmente integrado a uma rede interdiscursiva que, no Brasil, continuamente reforça simbólicas reciclagens da memória histórica referente ao período da Ditadura Militar (1964-1985) por meio da atualização da memória discursiva. Para tanto, a partir de conceitos-chave dentro do quadro teórico-metodológico da Análise do Discurso francesa, desenvolve-se um percurso conceitual pautado, sobretudo, nas noções de memória histórica, memória discursiva, interdiscurso e pré-discurso.

A proposta deste trabalho é investigar, à luz dos estudos discursivos, os efeitos de sentido emanados de memes, um gênero textual fabricado no meio digital e que tem esse espaço como cenário de circulação. Aqui, focalizamos na análise da heterogeneidade mostrada em “memes de internet”. Pretendemos revelar que, para compreender, efetivamente, tais textos, é preciso entender o entrecruzamento de diferentes vozes sociais e, assim, diferentes discursos devem ser mobilizados, assumidos. Como corpus para análise, considerando o atual momento político tão conturbado na história de nosso país, em que eleitores da direita e esquerda encenam uma polarização bem marcada, elegemos seis memes. Essas materialidades foram pinçadas de duas páginas do Facebook: “bolsomitos” e “bolsolixos”. Para os movimentos de análise, consideramos o processo de construção do interdiscurso e as refrações de sentidos provenientes da materialidade, priorizando as ressonâncias históricas, culturais e sociais. Como resultado, notamos que os dois grupos produziram memes, com recortes estratégicos, a fim de projetar representações (negativas) dos políticos que não apoiam e exaltar os que defendem, através de representações favoráveis a estes. Também percebemos que a produção de sentidos, pelo leitor, é possível a partir da mobilização de aspectos polifônicos, cujas redes verbal e não-verbal estão, intimamente, ancoradas aos aspectos históricos, culturais e sociais, alguns mais bem situados historicamente, outros nem tanto.
Os textos que um texto esconde...

Published: January 2021

Leitura e escrita são atividades interativas, uma vez que quem escreve o faz com um propósito: dizer algo a alguém, seu interlocutor, com uma intenção, de uma determinada forma, numa dada situação. O texto como textualização do discurso é uma atividade coconstruída, efeito de sentidos entre interlocutores. Na concepção interacionista, a produção textual pressupõe um conteúdo interior que se projeta para o exterior pela expressão. O que temos, então? Um sujeito, com sua consciência, suas intenções, seus impulsos e seus gostos, que, pretendendo exteriorizar seu discurso, seu a-dizer, se transforma em autor. E o texto, o dito, é, por conseguinte, a ponte que permite ao leitor – o seu interlocutor – ter acesso ao discurso e ao sujeito que o produziu. Autor e leitor são dotados de uma memória discursiva presente no processo de produção e leitura do texto, um evento interpretativo, que contém já ditos que subjazem ao dito ou estão implícitos nele, evidenciando a interdiscursividade/intertextualidade. Nessa perspectiva, um mesmo texto admite a possibilidade de muitas leituras. Como a construção de sentido se faz na interação autor-leitor por meio do texto, o leitor é alçado ao status de autor - coautor ou coenunciador - do novo texto produzido com a leitura.
Biofilm Theory for Lid Margin and Dry Eye Disease

Blepharitis and dry eye disease have long been viewed as two distinct diseases with overlapping presentations and separate etiologies. Evaporative dry eye, although frequently associated with aqueous deficiency, is also considered a separate entity. We propose viewing dry eye, both evaporative and insufficiency, as the natural sequelae of chronic blepharitis induced by biofilm. We suggest describing this one chronic disease as dry eye blepharitis syndrome (DEBS). The disease process begins when normal flora bacteria colonize the lid margin beginning shortly after birth. This colonization accompanies the development of a biofilm on the lid margin. As years pass, the biofilm matures, and the increased bacterial population initiates the production of inflammatory virulence factors, such as exotoxins, cytolytic toxins, and super-antigens, which persist on the lid margin for the rest of the patient’s life. These virulence factors cause early follicular inflammation and later, meibomian gland dysfunction followed by aqueous insufficiency, and finally, after many decades, loss of the dense collagen in the tarsal plate. We proposed four stages of DEBS, which correlate with the clinical manifestations of folliculitis (anterior blepharitis), meibomitis (meibomian gland dysfunction), lacrimalitis (aqueous deficiency), and lid structure damage evidenced by increased lid laxity resulting in entropion, ectropion, and floppy eyelid syndrome.

Air of cities especially in the developing parts of the world is turning into a serious environmental interest. The air pollution is because of a complex interaction of dispersion and emission of toxic pollutants from manufactories. Air pollution caused due to the introduction of dust particles, gases, and smoke into the atmosphere exceeds the air quality levels. Air pollutants are the precursor of photochemical smog and acid rain that causes the asthmatic problems leading into serious illness of lung cancer, depletes the stratospheric ozone, and contributes in global warming. In the present industrial economy era, air pollution is an unavoidable product that cannot be completely removed but stern actions can reduce it. Pollution can be reduced through collective as well as individual contributions. There are multiple sources of air pollution, which are industries, fossil fuels, agro waste, and vehicular emissions. Industrial processes upgradation, energy efficiency, agricultural waste burning control, and fuel conversion are important aspects to reducing pollutants which create the industrial air pollution. Mitigations are necessary to reduce the threat of air pollution using the various applicable technologies like CO2 sequestering, industrial energy efficiency, improving the combustion processes of the vehicular engines, and reducing the gas production from agriculture cultivations.

III-V semiconductors present interesting properties and are already used in electronics, lightening and photonic devices. Integration of III-V devices onto a Si CMOS platform is already in production using III-V devices transfer. A promising way consists in using hetero-epitaxy processes to grow the III-V materials directly on Si and at the right place. To reach this objective, some challenges still needed to be overcome. In this contribution, we will show how to overcome the different challenges associated to the heteroepitaxy and integration of III-As onto a silicon platform. We present solutions to get rid of antiphase domains for GaAs grown on exact Si(100). To reduce the threading dislocations density, efficient ways based on either insertion of InGaAs/GaAs multilayers defect filter layers or selective epitaxy in cavities are implemented. All these solutions allows fabricating electrically pumped laser structures based on InAs quantum dots active region, required for photonic and sensing applications.

South America covers a large area of the globe and plays a fundamental function in its climate change, geographical features, and natural resources. However, it still is a developing area, and natural resource management and energy production are far from a sustainable framework, impacting the air quality of the area and needs much improvement in monitoring. There are significant activities regarding laser remote sensing of the atmosphere at different levels for different purposes. Among these activities, we can mention the mesospheric probing of sodium measurements and stratospheric monitoring of ozone, and the study of wind and gravity waves. Some of these activities are long-lasting and count on the support from the Latin American Lidar Network (LALINET). We intend to pinpoint the most significant scientific achievements and show the potential of carrying out remote sensing activities in the continent and show its correlations with other earth science connections and synergies. In Part I of this chapter, we will present an overview and significant results of lidar observations in the mesosphere and stratosphere. Part II will be dedicated to tropospheric observations.
Offshoring-Outsourcing and Onshoring Tradeoffs: The Impact of Coronavirus on Global Supply Chain

The world has become a global village with companies investing in different nations to remain afloat and competitive. In the process of offshoring- outsourcing, companies and nations have become interdependent in their efforts to bridge the supply chain network. However, during a pandemic, such as the Coronavirus (COVID-19) that involved the closure of borders, and during which there was a high demand of lifesaving machines and personal protective equipment, many countries were left scrambling for critical medical products such as ventilators and personal protective equipment for doctors. Hence, the tendency away from offshoring and outsourcing to onshoring production. COVID-19 has elicited that countries need to invest in an onshore business if they are to remain afloat. However, investing in onshore (local) business calls for a tradeoff, which some countries cannot afford. Many countries lack skilled labour (developing countries), and where available, it is too expensive (developed countries) making onshore an expensive venture. Besides, promoting manufacturing companies means increased air pollution and greenhouse gases that are responsible for 4.2–7.0 million premature deaths every year, and which costs $4.6 trillion per year. Such death rates and cost can hinder the onshore business. Therefore, for countries to survive in the era of a pandemic, the best alternative is to build strong ties with offshore-outsource nations.
