New Analytical Model for Swellable Materials
Authors: Zahid Qamar Sayyad , Akhtar Maaz , Pervez Tasneem
Published: October 2021

As discussed in Chapter 6, numerical prediction of swelling can be attempted using existing hyperelastic material models available in commercial finite element (FE) packages. However, none of these models can accurately represent the behavior of swelling elastomers. The major shortcoming of currently available swelling models is that they consider Gaussian statistics for mechanical contribution of configuration entropy, which is based on chains having limited extensibility. Some later models (not yet incorporated into commercial FE packages) can give a reasonable account of certain behavior patterns in swelling elastomers, but do not explain other aspects well. One of the new approaches is to treat swelling elastomers as gels. As described earlier, gels are mostly liquid, yet they behave like solids due to a three-dimensional cross-linked network within the liquid. Many authors consider gel as poro-elastic or porous and use Darcy’s law to model the amount of fluid influx. However, a swollen elastomer mostly consists of the solvent. When an external load is applied, maximum resistance comes from the solvent molecules as in diffusion. Also, most of the new models are quite complex in concept and formulation, and there is a serious need for a scientifically simpler model.
Sleeve-Plus Procedures in Asia: Duodenojejunal Bypass and Proximal Jejunal Bypass
Authors: Bernadette C. Lim-Loo Michelle , Huang Chih-Kun , Chan Valerie , Chua Kathleen
Published: October 2021

Laparoscopic sleeve gastrectomy (SG) is the most commonly done bariatric procedure worldwide due to its technical ease. However, the physiologic effects of this procedure have limitations on glucose homeostasis for patients with type 2 Diabetes Mellitus (T2DM). This is due to the insufficient physiologic modulations from intestinal hormones. The Roux-en-Y gastric bypass (RYGB) has been proven to have better T2DM remission than SG due to more pronounced physiologic changes from foregut and hindgut hormone modulations. However, RYGB is technically challenging to perform and is accompanied by many potential postoperative complications, especially in terms of nutrition. The addition of an intestinal bypass to SG also induces said intestinal hormone changes to enhance diabetes remission. This chapter discusses the intestinal bypass that may be added to SG as surgical options for the treatment of obesity and T2DM with focus on duodenojejunal and proximal jejunal bypass.
Hyaluronic Acid Fillers: Where We Have Been and Where We Are Going
Authors: Daoud Alexander , Weiss Robert
Published: October 2021

Since the approval of the United States’ first hyaluronic acid (HA) filler in December 2003, HA fillers have become mainstays of soft tissue augmentation due to their favorable safety profile and minimally invasive treatment nature. The past two decades have not only brought an expansion in the popularity of HA fillers, but also in the number of available HA filler products and indications for cosmetic enhancement. Accordingly, HA filler injection has become one of the most commonly performed cosmetic procedures worldwide. The progression of HA filler products is a study in both biomedical engineering advancements, as well as evolving concepts of beauty and cosmesis. In this chapter, we review the history of these products, including their composition and indications for use. We then explore the prospect of HA fillers for the future of esthetic medicine, as they remain a vital component of nonsurgical soft tissue augmentation.
Feminist Thought. A Theoretical Approach
Authors: Cavarero Adriana , Fulvi Daniele ,   Philosophy Documentation Center
Published: October 2021

In this essay, Cavarero thematically highlights the main issues of feminist thought, by criticizing the patriarchal system and its theoretical products—such as the concepts of complementarity of the sexes and of equality—through the lens of sexual difference. In doing so, she radically criticizes the so-called binary economy, namely the interpretative model on which the patriarchal system is based, in which the sole male sex is self-represented, establishing at the same time a representation of the female sex that is functional to men. Accordingly, by criticizing both the traditional and the postmodern approach, she aims to rethink from a feminist point of view the question of the subject, of the identity, and of the self. In this respect, she advances an account of the self as relational, namely a self that is given only through its relationship with others, hence rejecting the abstract universality of the male subject of traditional metaphysics. Subsequently, Cavarero presents a notion of identity as an interplay of relations that makes it fluid and dynamic, and not as fixed and permanent, as per the metaphysical tradition that understands it as universal substance. In conclusion, she argues that the unicity of the self—and of each human being—can be grasped only through a narrative discourse that counterposes the philosophical investigations on the essence of an absolute and universal principle of reality, and emphasizes the singular and unrepeatable nature of the self.

Light and Electron-Microscopic Studies on the Paraepiglottic Tonsil of the Buffalo (Bubalus bubalis)
Authors: Girgiri Ibrahim Alhaji , Kumar Pawan
Published: October 2021

The paraepiglottic tonsil present on either side of the base of the epiglottis constitutes a small portion of the mucosa-associated lymphoid tissue. The present study was conducted on the paraepiglottic tonsils of 12 adult buffaloes of the local mixed breed to explore its basic histomorphological, histochemical, and ultrastructural characteristics and to compare with other tonsils of the oral region to ascribe immunological function. The tonsil mucosa was lined by partly stratified squamous keratinised epithelium towards the outer surface and a stratified squamous non-keratinised epithelium towards the shallow crypts. The non-keratinised epithelium modified into reticular type due to infiltration of underlying lymphoid tissue was characterised by the predominance of the lymphoid cells, interrupting basement membrane and indistinct strata. The reticular epithelium at places presented a spongy appearance. The loose irregular connective tissue of propria-submucosa was mainly comprised of glandular and lymphoid tissue. The lymphoid tissue was mainly in the form of isolated lymphocytes, diffuse aggregations, and lymphoid follicles. The inter-follicular areas showed the presence of high endothelial venules. The sero-mucous type of glandular acini presented a strong reaction for glycogen, acidic mucosubstances, weakly sulfated mucosubstances, mucin, and the presence of more than 4% cysteine in their secretions. The tonsils under scanning electron microscopy presented an undulating appearance due to the presence of crest and folds. Higher magnification revealed squamous cells having various patterns and arrangements of microplicae. Small pits visualised on the mucosal surface represented openings of the glandular ducts. The cells towards the lumen of some glandular ducts appeared whorl-like where typical microplicae were absent. The transmission electron microscopy of different strata of different types of epithelia showed varying cell organelles, especially the mitochondria, endoplasmic reticulum, Golgi apparatus, and few filaments. The structural features of the tonsil were similar to those of other oral tonsils and suggested their immunological role, which might be of importance to local immunity.
Redundancy in ELF: A Corpus-Based Study on Negative and Modal Concord
Authors: Watkowska Dorota
Published: October 2021

English as a lingua franca (henceforth ELF) is a contact language that has attracted great attention due to its unique global role. Thus, numerous studies have been conducted to determine its characteristics, among which research on such processes as, for example, simplification, added prominence or redundancy underlying language use in the ELF context is of the main interest. Therefore, the paper aims to broaden the per- spective on redundancy in ELF, focusing on negative and modal concord in spoken and written data. With the reliance on VOICE, ELFA, and WrELFA corpora, the analysis shows that both phenomena are noticeable in ELF; however, while redundancy in terms of modal concord appears in spoken and written ELF, negative concord is characteristic only of spoken data.
Development of Metalinguistic Awareness in EFL Vocabulary and Spelling: A Longitudinal Case Study of a Child and Adult with Dyslexia
Authors: Kałdonek-Crnjaković Agnieszka
Published: October 2021

This longitudinal case study aimed at investigating the development of metalin- guistic awareness in EFL spelling and vocabulary in two Croatian learners with dyslexia who differed in age and language proficiency – a child and an adult. They attended weekly sessions that aimed at improving their English spelling and vocabulary. The data were collected for 45 weeks using the teacher’s notes and audio-recorded lesson observations. The results showed that the participants developed their metalinguistic skills; however, the age and language proficiency factor was salient. Also, the metacognitive component of the instruction had a different effect on the development of metalinguistic skills in spelling and vocabulary acquisition. Pedagogical implications are discussed.

Published: October 2021

Dry ecosystems, despite their relative levels of aridity, are very diverse, and play a vital role in the livelihoods of many dryland inhabitants. It is therefore critical to investigate the relationship between land-use change and soil quality parameters to offer a scientific basis for optimizing land-use planning and improving soil quality status in dry ecosystems and ecologically vulnerable areas. This study, therefore, analyzed the physicochemical properties of soils in five different land-use types namely farmland, abandoned farmland, natural grassland, artificial lemon forest, and poplar woodland at YongDeng County. The soil quality status of the aforementioned land-use types was also evaluated through Principal component analysis. The results revealed that abandoned farmland and natural grassland recorded the highest average values of soil coarse particles of 24.0% and 23.4% respectively compared to the other land-use types. The highest average value (46.1%) of fine soil particles was recorded in poplar woodland followed by natural grassland (36.6%) and the average value of very fine soil particles was higher in farmland (40.8%) and artificial lemon woodland (38.3%) than in the other land-use types. The average value of clayey particles was highest in farmland (11.1%), followed by artificial lemon woodland (9.3%), and abandoned farmland (6.5%), then poplar woodland which recorded an average value of (4.2%). The average values of Soil water content, soil pH, soil electrical conductivity, and soil total nitrogen content were significantly higher in farmland compared to the other land-use types. Soil organic carbon content was significantly higher in abandoned farmland at (P < 0.03) and lemon woodland at (P < 0.01) than in farmlands, natural grasslands, and poplar stands. The soil quality indicators of the different land-use types were significantly correlated with each other. Among them, the correlation coefficient of each evaluation index was highest in poplar woodland, followed by natural grassland, lower in farmland and artificial lemon woodland, and lowest in abandoned farmland. The overall soil quality scores were in the following order: farmland > abandoned farmland > 0 > grassland > lemon woodland > poplar woodland. In the study area, the soil quality of farmland that has been finely managed and naturally restored to grassland following abandonment is superior, whereas the soil quality of natural grassland, artificial lemon woodland, and poplar forest land is substandard. The comprehensive analysis of soil quality demonstrates that conservation tillage and fine management of water-irrigated farmland, as well as the natural conversion of abandoned farmland to grassland, can significantly improve the soil quality of sandy soils, reduce water and soil loss, increase fertility, and gradually improve regional ecological environmental conditions.
Age and lunar cycle predict harbor porpoise bycatch in the south-western Baltic Sea
Authors: Brennecke Dennis , Wahlberg Magnus , Gilles Anita , Siebert Ursula
Published: October 2021

The harbor porpoise,Phocoena phocoena, is the only cetacean regularly occurring in the Baltic Sea. During the last decades, several anthropogenic activities have affected porpoises in the Baltic region. Most notably is bycatch in static fishing gear, such as gill nets, which is the main human-induced cause of death in odontocetes. There is still considerable uncertainty about which factors influence the amount of bycatch. In the present study, we reviewed bycatch data collected from 1987 to 2016 from the south-western Baltic Sea. There was a significant difference in bycatch due to seasonality and region, and there was a higher bycatch rate in juveniles than in adults. The only abiotic factor associated with bycatch was the lunar cycle, with more animals bycaught during a full moon. These results improve our understanding of which biotic and abiotic factors are associated with bycatch of Baltic harbor porpoises, which can be used to strengthen conservation endeavors such as managing fishing efforts.
In vitro induction and identification of polyploid Neolamarckia cadamba plants by colchicine treatment

Published: October 2021

Polyploidization has played a crucial role in plant breeding and crop improvement. However, studies on the polyploidization of tropical tree species are still very scarce in this region. This paper described the in vitro induction and identification of polyploid plants of Neolamarckia cadamba by colchicine treatment. N. cadamba belongs to the Rubiaceae family is a natural tetraploid plant with 44 chromosomes (2n = 4x = 44). Nodal segments were treated with colchicine (0.1%, 0.3% and 0.5%) for 24 h and 48 h before transferring to shoot regeneration medium. Flow cytometry (FCM) and chromosome count were employed to determine the ploidy level and chromosome number of the regenerants, respectively. Of 180 colchicine-treated nodal segments, 39, 14 and 22 were tetraploids, mixoploids and octoploids, respectively. The highest percentage of polyploidization (20% octoploids; 6.7% mixoploids) was observed after treated with 0.3% colchicine for 48 h. The DNA content of tetraploid (4C) and octoploid (8C) was 2.59 ± 0.09 pg and 5.35 ± 0.24 pg, respectively. Mixoploid plants are made up of mixed tetraploid and octoploid cells. Chromosome count confirmed that tetraploid cell has 44 chromosomes and colchicine-induced octoploid cell has 88 chromosomes. Both octoploids and mixoploids grew slower than tetraploids under in vitro conditions. Morphological characterizations showed that mixoploid and octoploid leaves had thicker leaf blades, thicker midrib, bigger stomata size, lower stomata density, higher SPAD value and smaller pith layer than tetraploids. This indicates that polyploidization has changed and resulted in traits that are predicted to increase photosynthetic capacity of N. cadamba. These novel polyploid plants could be valuable resources for advanced N. cadamba breeding programs to produce improved clones for planted forest development.
The Effect of HRM Practices: Performance Appraisal System and Career Development on Turnover Intention
Authors: Rajapakshe Wasantha
Published: October 2021

The purpose of this study is to determine the impact of Performance Appraisal System (PAS) and Career Development (CD) on Turnover Intention (TI). The sample was made up of executive-level employees from large-scale garment factories in Sri Lanka. For the final data analysis, 386 samples were used. The hypotheses were tested using structural equation modeling. According to the findings, PAS has a significant negative impact on TI, whereas CD has a positive impact on TI. The study concluded that improving Performance Appraisal Satisfaction can lower employees' Turnover Intention, whereas improving Career Development lowers employees' TI. Improved Career Advancement in this case indicates that employee CD expectations are high. As a result, the organization should develop Performance Appraisal and Career Development strategies, especially for executives. Many studies in the garment industry look at the social and working environments, but little is said about how PAS and CD affect TI. The findings have theoretical implications, filling a literature gap.

Published: October 2021

There are criteria that certify the sustainable potentials of any built environment. Low income housing scheme proposed by Enugu state government for its workers is targeted at Nachi, Udi local government area in Enugu state, Nigeria. To assess the capability of this location for the project, site investigation and experimental design methods were adopted to measure the geo-morphological and hydrologic features and conduct laboratory tests on the basic and strength properties of the formation respectively. Findings explain that Nachi lies on the slope of 700; hence the average runoff is high. Prolific confined aquifer result to underground water potential for consumption since the formation is porous with high elevation at 221 meters. It is also discovered that the area possesses low shear strength which is capable of resisting the high shear stress measured in the soil sample of the formation. Soil plasticity is measured as 10 indicating high erodible potential. The particle size distribution of the formation is poorly sorted with high percentage of sand particles, and very low percentage of gravel, with intercalation of compressible particles in the formation. The rain intensity is measured high with very high rate of runoff potential that is capable of causing erosion on the sloppy terrain with low bearing strength. The study therefore concludes that Nachi as a proposed site for the low housing scheme is not suitable considering the fact that the initial cost involved in preparing standard foundation of the buildings and the surrounding for sustainable housing will make it exorbitant for the low income earners. Any effort to compromise doing the right things from the beginning for a sustainable housing will degenerate the housing to high maintenance culture when in use. In the absence of no other available land the study therefore recommends that edicts and official programmes be enacted and instituted respectively to curb down erosion menace in the area with standard foundation designs that will guarantee safety to the buildings effectively in the area. If the housing scheme must stand for the low income earners the government must as matter of policy subsidize the cost of the houses reasonably such that the workers in the state can easily afford them.

Eradication of Malaria: Present Situations and New Strategies
Authors: Alsulami Muslimah N.
Published: October 2021

Malaria is a serious disease caused by the protozoon parasite Plasmodium and transmitted by the female Anopheles mosquito as a vector.  P. falciparum is the gravest infection for all other species P. ovale, P. vivax, P. Malariae and P. knowlesi in terms of morbidity or mortality, which is why most research focused on P. falciparum. The disease affects about 300-500 million people, mostly in the tropics. In regions with a weak economic downturn in tropical and subtropical capital, morbidity and mortality have elevated. Malaria remains a persistent threat in recent research. At the beginning of the 20th century, scientists tried to describe a successful way of eradicating malaria.  However, the presence of drug resistance and social and environmental problems, no acceptable and positive future solution has been pointed out. Several studies have highlighted the need to establish advanced nano-biotechnology treatment, novel anti-malarial drug targets, an efficient malaria vaccine technique, and Anopheles gene editing, which opened the door to a healthy, environmentally friendly malaria treatment method over the last two decades. In recent years, the use of mosquito microbiota has shown great potential for cutting down the transmission of mosquito-borne pathogens. This review aims to cover important issues in malarial eradication as rapid diagnostic technology, novel anti-malarial drug targets, Anopheles gene editing, use of mosquito microbiota, and recent vaccines.

Published: October 2021

In this paper, we tried to show the existence of excess volatility of stock prices in the Tunisian stock exchange during the period 2000 - 2017, by applying the variance bounds of Shiller. We used data on daily closing prices and the transaction volume of 22 companies listed on Tunisian Financial market during the period 2016/2017 to identify the relationship between over confidence bias and the Excess Volatility via the Granger causality test. Based on Chuang and Lee’s approach, we studied the effect of the excess confidence component on volatility by the E-GARCH Model (1.1). Our results show that high market volatility resulted from overconfident investors.
Caça às bruxas: a criminalização do aborto e as implicações para as mulheres na atualidade
Authors: Zahluth Carolina Messeder , Lima Maria Lúcia Chaves , Dias Bárbara Lou da Costa Veloso
Published: October 2021

O artigo visa discutir as semelhanças entre o atual debate sobre a criminalização do aborto e a histórica caça às bruxas na Baixa Idade Média, buscando pontuar os efeitos que essa relação ocasiona nos corpos e nas vivências femininas. Para tal, faz-se uma breve contextualização da história da caça às bruxas na Idade Média como um evento essencial para a difusão do capitalismo e expropriação dos corpos e funções reprodutivas das mulheres, além de contextualizar o atual debate sobre aborto no Brasil como uma tensão entre os movimentos feministas e os grupos conversadores e religiosos. Foram identificadas três semelhanças principais entre a caça às bruxas e a criminalização atual do aborto: a dominação e expropriação dos corpos e funções reprodutivas femininas; os dois períodos perseguem, matam e deixam mais vulneráveis mulheres pobres e periféricas; e ambos criam e perpetuam uma cultura misógina que incita a violência e os crimes de ódio contra mulheres.
A Retórica do “cidadão de bem”, no discurso de Jair Bolsonaro - um presidenciável em construção
Authors: Lima Isabelly Cristiany Chaves , Lima Elizabeth Christina de Andrade
Published: October 2021

Ódio, medo, inimigos, terroristas, crimes, violências. Esses léxicos têm sido a materialidade discursiva que cimenta a construção da imagem pública política do presidenciável Jair Messias Bolsonaro. Partindo de uma densidade política modesta, subestimada como modelo de rápida desidratação, para um fenômeno político, que traz à tona um esfacelamento da democracia, um projeto conservador, um aprofundamento do neoliberalismo, Bolsonaro fabrica a retórica do “cidadão de bem”, estimula o ódio e fomenta o medo, violando direitos e garantias fundamentais. Dessa forma, tomando como aporte teórico os conceitos de Poder Simbólico em Bourdieu, das noções de Gênero em Scott, da Disciplinarização em Foucault, do Ressentimento em Elias e do Simbolismo em Mauss, a presente produção textual tem como objetivo partir de um dado empírico, isto é: uma entrevista concedida a um canal aberto de televisão, RedeTV!, para refletir sobre as materialidades que compõem o capital político do então deputado federal, cuja retórica é assentada nas relações de opressão, sobretudo, referentes às expressões de gênero e às práticas sexuais. Portanto, pode-se afirmar que o discurso de Bolsonaro, eivado de ódio, torna propenso atos de preconceito e acentua os modos de agir segregatórios.
Masculinidades contemporâneas em disputa // Contemporary masculinities in dispute
Authors: Thürler Djalma , Medrado Benedito
Published: October 2021

Em nosso país, as medidas sanitárias de prevenção, baseadas no confinamento, têm evidenciado e acentuado diferenças e desigualdades, especialmente no campo das relações de gênero. Não à toa, o tema da violência doméstica e familiar tem atraído a atenção de pesquisadores/as e de ativistas feministas. Na mesma direção, tem também alimentado reflexões sobre regimes de verdade que conformam as relações de gênero de tal modo que ao homem e ao masculino são destinados os espaços da gestão da vida pública, e às mulheres e ao feminino, a ordem pública. Nesse sentido, pensar masculinidades contemporâneas em disputa, hoje, é um exercício em construção e em transformação.

Religar para que e para quem? Novas perspectivas nos estudos de religiosidade e dissidências sexuais e de gêneros - uma breve apresentação
Authors: Duccini Luciana , Nogueira Sidnei Barreto , Rocha Felipe , Dias Claudenilson
Published: October 2021

No momento que atravessamos, a mera junção de palavras como gênero e sexualidade com religião faz soar um alarme e isso não é surpreendente, uma vez que temos assistido a um constante ataque aos direitos sexuais, de gênero e reprodutivos por parte de certos grupos religiosos, como a Igreja Católica e algumas das maiores igrejas evangélicas do país. Fatos ainda recentes, tais como a oposição ferrenha, em 2011, dos parlamentares evangélicos ao Caderno Escola sem Homofobia, apelidado de "kit gay", e a escolha do deputado e pastor Marco Feliciano para a presidência da Comissão de Direitos Humanos e Minorias (CDHM) da Câmara dos Deputados, em 2013, de onde procurou avançar Projetos de Lei contrários aos direitos LGBTQIA+ (SALES; MARIANO, 2019, p. 17), lançaram as bases para este alarme. De 2013 até o presente, a situação parece ter apenas piorado, culminando na eleição de um presidente abertamente conservador, homofóbico e sexista.

Este texto analiza el rol de la traducción en la formación de las políticas de liberación sexual en las Américas. Este artículo desafía una narrativa dominada por la cultura anglosajona para reconstruir los circuitos alternativos de diálogo y conflicto entre los movimientos homosexuales del hemisferio. El artículo argumenta que los espacios de conflicto político, estético y teóricos jugaron un rol fundamental en la radicalización política de estos movimientos. Para ello se analiza un conjunto de documentos del Frente de Liberación Homosexual Argentino (FLHA), en el Frente de Liberación Homosexual Mexicano (FLHM), el Frente Homosexual de Acción Revolucionaria de México (FHAR), el Third World Gay Revolution (TWGR), la revista Afuera y el Comité Homosexual Latinoamericano (COHLA).
“Hay Muchísimo Poder en la Oscuridad” : Black Cuir Cinema Clubs in Contemporary Havana
Authors: Speakman Maile
Published: October 2021

Cineclub Cuir and Cine Alternativo are itinerant cinematic events aimed at showing cuir, feminist, avant-garde, Afro-diasporic, and experimental media content in Havana. El paquete semanal is a widespread digital information product that Cubans use to access global media. I argue that Cineclub Cuir and Cine Alternativo’s curatorial frameworks produce exploratory spaces of moving theory that rupture the revolutionary state’s nationalist discourse of colorblindness and racial democracy and the normative and white-washed depictions of queerness that circulate in el paquete. The cinema clubs, which elude state-sponsorship and are free of charge, create collective discursive spaces where participants interrogate the figure of the cuir racializado in sites that are not fully regulated by the state or Cuba’s commodified media markets. The emergence of such spaces in the past three years marks a break with the Cuban state’s post-revolutionary monopoly on cultural spaces but also a resistance to newer, more capitalist forms of media circulation such as el paquete. By projecting moving images of Black queer intimacy in alleyways, rooftops, and a multitude of other public and private spaces throughout Havana, Cineclub Cuir and Cine Alternativo comprise a media infrastructure that is ephemeral, difficult to police, and that contravenes the colonial racial and spatial logics that organize the city.

Prazer, eu sou arte, meu querido: apontamentos historiográficos para uma genealogia da travestilidade drag queen
Authors: Ribeiro dos Santos Thiago Henrique
Published: October 2021

O espraiamento das audiovisualidades drag queens em mídias nacionais e internacionais tem instigado nosso olhar a resgatar rastros de suas presenças no mundo em diferentes contextos socioculturais. A fim de tentar cartografar focos dessa metamorfose de gênero enquanto manifestação artística em pontos distantes no tempo e no espaço, este artigo, então, recolhe fragmentos bibliográficos, a partir de Amanajás (2014), Baker (1994), Berthold (2001), Newton (1972) e Trevisan (2004), para propor uma possível genealogia da travestilidade drag queen em culturas orientais e ocidentais.
Quando a "interdição" tenta invadir a escola e "ex-comungar" as diferenças: algumas reflexões (in)discretas sobre o projeto "Escola Sem Partido"
Authors: Oliveira Esmael Alves de , Passamani Guilherme Rodrigues , Duque Tiago
Published: October 2021

Neste artigo buscamos refletir sobre as tramas discursivas que cercam o projeto “Escola sem partido” a partir de dois eventos políticos ocorridos respectivamente nas cidades de Dourados e Campo Grande, em Mato Grosso do Sul. Se, como afirma Foucault (2012), o discurso não é transparente, ao mapearmos as redes político-ideológicas que dão corpo a tal projeto, por meio dos atores envolvidos, dos argumentos e categorias utilizadas, do contexto político-social em que se insere e dos jogos de interesses, objetivamos perceber as contradições, os embaraços, os tensionamentos e os pontos cegos presentes no próprio discurso, que nos permitem questionar os dispositivos de “verdade” e “imparcialidade” em que se buscam resguardar. Ao contrário do que afirma e pretende, uma escola sem partido é não apenas impossível, inviável e insustentável, mas também indesejável.
“Agora eles foram longe demais”: as crianças, as famílias e as super-heroínas drag queens
Authors: Rosa Cristiano Eduardo da , Felipe Jane
Published: October 2021

Este estudo problematiza a animação brasileira “Super Drags”, original da plataforma Netflix, e a sua repercussão referente à preocupação de famílias e políticos quanto à classificação indicativa e ao conteúdo da referida produção, trazendo como super-heróis a presença de personagens homossexuais e drag queens. Com a análise dos cinco episódios que compõem a temporada da série e as notas de repúdio propagadas, percebemos a intencionalidade da produção destinada para o público adulto, mas suscitamos também debates acerca da responsabilidade familiar no acesso de crianças e adolescentes a conteúdos online e o temor em relação ao que o desenho animado provoca frente a sua representatividade LGBT no país que mais provoca a morte de lésbicas, gays, bissexuais, travestis e transexuais no mundo, com índices crescentes a cada ano. As análises aqui apresentadas se pautam nos Estudos de Gênero e nos Estudos Culturais, a partir da perspectiva pós-estruturalista.
A história que (quase) ninguém conta: as/os dissidentes do heteroCistema na educação básica e nas passarelas do samba
Authors: Romani Gomes Fabrício
Published: October 2021

O desfile da GRES Estação Primeira de Mangueira em 2019 ainda não terminou. O enredo apresentado pela escola de samba, que trouxe questionamentos sobre a História narrada nos livros didáticos e denunciou a existência de uma série de páginas ausentes nessas obras, provocou a produção deste artigo. Entre as ausências nos livros de História temos aquelas que contam as trajetórias individuais ou coletivas dos dissidentes do heteroCistema. Onde estão as páginas que contam as histórias daqueles que não são heterossexuais, daqueles que não são cisgêneros, ou, ainda, daqueles que não se enquadram nos binarismos sexual e de gênero? Buscando encontrar essas páginas, fui à procura de informações em livros didáticos de História e em enredos apresentados pelas escolas de samba nos carnavais do Rio de Janeiro, São Paulo e Porto Alegre. Dessa forma, aqui, entendo a aula de História na educação básica e o desfile das escolas de samba como práticas de história pública.

Groups often make better judgements than individuals, and recent research suggests that this phenomenon extends to the deception detection domain. The present research investigated whether the influence of groups enhances the accuracy of judgements, and whether group size influences deception detection accuracy. Two‐hundred fifty participants evaluated written statements with a pre‐established detection accuracy rate of 60% in terms of veracity before viewing either the judgements and rationales of several other group members or a short summary of the written statement and revising or restating their own judgements accordingly. Participants' second responses were significantly more accurate than their first, suggesting a small positive effect of structured groups on deception detection accuracy. Group size did not have a significant effect on detection accuracy. The present work extends our understanding of the utility of group deception detection, suggesting that asynchronous, structured groups outperform individuals at detecting deception.
Organic Thin‐Film Transistors as Cannabinoid Sensors: Effect of Analytes on Phthalocyanine Film Crystallization

With a growing international trend of Cannabis legalization, there is a present need for on‐the‐spot, low cost, and rapid detection of cannabinoids. Here, relationships between thin‐films of phthalocyanines (Pcs) with a variety of central, peripheral, and axial substituents and their response to the cannabinoid Δ9‐tetrahydrocannabinol (THC), with and without a cannabinoid‐sensitive chromophore (Fast Blue BB) are investigated through organic thin‐film transistor (OTFT) performance. X‐ray diffraction and UV–vis absorption spectroscopy measurements demonstrate significantly altered film morphologies and the formation of new crystal orientations in response to analytes, which are corroborated by scanning electron microscopy. Electron paramagnetic resonance further corroborates shifting crystal structures in response to THC and also reveals the formation and promotion of Pc radical species through THC‐metal coordination. With exposure to THC, aluminum chloride Pc generates the largest physical film changes as well as the largest changes in OTFT performance. These findings suggest that the semiconductor thin‐film morphologies in Pc‐based OTFT sensors are not static in the presence of analytes and that the sensing response is driven both by strong analyte‐Pc coordination and bulk film restructuring to accommodate these interactions.

The combination of semiconductivity and tunable ferromagnetism is pivotal for electrical control of ferromagnetism and next‐generation low‐power spintronic devices. However, Curie temperatures (TC) for most traditional intrinsic ferromagnetic semiconductors (≤200 K) and recently discovered two‐dimensional (2D) ones (<70 K) are far below room temperature. 2D van der Waals (vdW) semiconductors with intrinsic room‐temperature ferromagnetism remain elusive considering the unfavored 2D long‐range ferromagnetic order indicated by Mermin–Wagner theorem. Here, vdW semiconductor CrxGa1−xTe crystals exhibiting highly tunable above‐room‐temperature ferromagnetism with bandgap 1.62–1.66 eV are reported. The saturation magnetic moment (Msat) of CrxGa1−xTe crystals can be effectively regulated up to ≈5.4 times by tuning Cr content and ≈75.9 times by changing the thickness. vdW CrxGa1−xTe ultrathin semiconductor crystals show robust room‐temperature ferromagnetism with the 2D quantum confinement effect, enabling TC 314.9–329 K for nanosheets, record‐high for intrinsic vdW 2D ferromagnetic semiconductors. This work opens an avenue to room‐temperature 2D vdW ferromagnetic semiconductor for 2D electronic and spintronic devices.
