Background

Women prescribed antidepressants face the dilemma of whether or not to continue their treatment during pregnancy. Currently, limited evidence is available on the efficacy of continuing versus discontinuing antidepressant treatment during pregnancy to aid their decision. We aimed to estimate whether antidepressant discontinuation before or during pregnancy was associated with an increased risk of psychiatric emergency (ascertained by psychiatric admission or emergency room visit), a proxy measure of severe exacerbation of symptoms/mental health crisis.

Methods and findings

We carried out a propensity score–matched cohort study of women who gave birth to live-born singletons between January 1, 1997 and June 30, 2016 in Denmark and who redeemed an antidepressant prescription in the 90 days before the pregnancy, identified by Anatomical Therapeutic Chemical (ATC) code N06A. We constructed 2 matched cohorts, matching each woman who discontinued antidepressants before pregnancy (N = 2,669) or during pregnancy (N = 5,467) to one who continued antidepressants based on propensity scores. Maternal characteristics and variables related to disease severity were used to generate the propensity scores in logistic regression models. We estimated hazard ratios (HRs) of psychiatric emergency in the perinatal period (pregnancy and 6 months postpartum) using stratified Cox regression.

Psychiatric emergencies were observed in 76 women who discontinued antidepressants before pregnancy and 91 women who continued. There was no evidence of higher risk of psychiatric emergency among women who discontinued antidepressants before pregnancy (cumulative incidence: 2.9%, 95% confidence interval [CI]: 2.3% to 3.6% for discontinuation versus 3.4%, 95% CI: 2.8% to 4.2% for continuation; HR = 0.84, 95% CI: 0.61 to 1.16, p = 0.298). Overall, 202 women who discontinued antidepressants during pregnancy and 156 who continued had psychiatric emergencies (cumulative incidence: 5.0%, 95% CI: 4.2% to 5.9% versus 3.7%, 95% CI: 3.1% to 4.5%). Antidepressant discontinuation during pregnancy was associated with increased risk of psychiatric emergency (HR = 1.25, 95% CI: 1.00 to 1.55, p = 0.048). Study limitations include lack of information on indications for antidepressant treatment and reasons for discontinuing antidepressants.

Conclusions

In this study, we found that discontinuing antidepressant medication during pregnancy (but not before) is associated with an apparent increased risk of psychiatric emergency compared to continuing treatment throughout pregnancy.

Background

Regular and comprehensive epidemiological surveys of the filarial nematodesMansonella perstansandLoa loain children, adolescents and adults living across Bioko Island, Equatorial Guinea are lacking. We aimed to demonstrate that blood retained on malaria rapid diagnostic tests, commonly deployed for malaria surveys, could be used as a source of nucleic acids for molecular based detection ofM.perstansandL.loa. We wanted to determine the positivity rate and distribution of filarial nematodes across different age groups and geographical areas as well as to understand level of co-infections with malaria in an asymptomatic population.

Methodology

M.perstans,L.loaandPlasmodiumspp. parasites were monitored by qPCR in a cross-sectional study using DNA extracted from a subset malaria rapid diagnostic tests (mRDTs) collected during the annual malaria indicator survey conducted on Bioko Island in 2018.

Principal findings

We identified DNA specific for the two filarial nematodes investigated among 8.2% (263) of the 3214 RDTs screened. Positivity rates ofM.perstansandL.loawere 6.6% and 1.5%, respectively.M.perstansinfection were more prominent in male (10.5%) compared to female (3.9%) survey participants.M.perstansparasite density and positivity rate was higher among older people and the population living in rural areas. The socio-economic status of participants strongly influenced the infection rate with people belonging to the lowest socio-economic quintile more than 3 and 5 times more likely to beL.loaandM.perstansinfected, respectively. No increased risk of being co-infected withPlasmodiumspp. parasites was observed among the different age groups.

Conclusions/Significance

We found otherwise asymptomatic individuals were infected withM.perstansandL.loa. Our study demonstrates that employing mRDTs probed with blood for malaria testing represents a promising, future tool to preserve and ship NAs at room temperature to laboratories for molecular, high-throughput diagnosis and genotyping of blood-dwelling nematode filarial infections. Using this approach, asymptomatic populations can be reached and surveyed for infectious diseases beyond malaria.

Published: January 2022

Schistosomiasis remains a public health concern across sub-Saharan Africa; current control programmes rely on accurate mapping and high mass drug administration (MDA) coverage to attempt disease elimination. Inter-species hybridisation can occur between certain species, changing epidemiological dynamics within endemic regions, which has the potential to confound control interventions. The impact of hybridisation on disease dynamics is well illustrated in areas of Cameroon where urogenital schistosomiasis, primarily due to Schistosoma haematobium and hybrid infections, now predominate over intestinal schistosomiasis caused by Schistosoma guineensis. Genetic markers have shown the ability to identify hybrids, however the underlying genomic architecture of divergence and introgression between these species has yet to be established. In this study, restriction site associated DNA sequencing (RADseq) was used on archived adult worms initially identified as; Schistosoma bovis (n = 4), S. haematobium (n = 9), S. guineensis (n = 3) and S. guineensis x S. haematobium hybrids (n = 4) from Mali, Senegal, Niger, São Tomé and Cameroon. Genome-wide evidence supports the existence of S. guineensis and S. haematobium hybrid populations across Cameroon. The hybridisation of S. guineensis x S. haematobium has not been demonstrated on the island of São Tomé, where all samples showed no introgression with S. haematobium. Additionally, all S. haematobium isolates from Nigeria, Mali and Cameroon indicated signatures of genomic introgression from S. bovis. Adaptive loci across the S. haematobium group showed that voltage-gated calcium ion channels (Cav) could play a key role in the ability to increase the survivability of species, particularly in host systems. Where admixture has occurred between S. guineensis and S. haematobium, the excess introgressive influx of tegumental (outer helminth body) and antigenic genes from S. haematobium has increased the adaptive response in hybrids, leading to increased hybrid population fitness and viability.

Published: January 2022

Southern Russia remains affected by West Nile virus (WNV). In the current study, we identified the spatial determinants of WNV distribution in an area with endemic virus transmission, with special reference to the urban settings, by mapping probable points of human infection acquisition and points of virus detection in mosquitoes, ticks, birds, and mammals during 1999–2016. The suitability of thermal conditions for extrinsic virus replication was assessed based on the approach of degree-day summation and their changes were estimated by linear trend analysis. A generalized linear model was used to analyze the year-to-year variation of human cases versus thermal conditions. Environmental suitability was determined by ecological niche modelling using MaxEnt software. Human population density was used as an offset to correct for possible bias. Spatial analysis of virus detection in the environment showed significant contributions from surface temperature, altitude, and distance from water bodies. When indicators of location and mobility of the human population were included, the relative impact of factors changed, with roads becoming most important. When the points of probable human case infection were added, the percentage of leading factors changed only slightly. The urban environment significantly increased the epidemic potential of the territory and created quite favorable conditions for virus circulation. The private building sector with low-storey houses and garden plots located in the suburbs provided a connection between urban and rural transmission cycles.
Genomic data support the taxonomic validity of Middle American livebearers Poeciliopsis gracilis and Poeciliopsis pleurospilus (Cyprinodontiformes: Poeciliidae)

Published: January 2022

Poeciliopsis (Cyprinodontiformes: Poeciliidae) is a genus comprised of 25 species of freshwater fishes. Several well-known taxonomic uncertainties exist within the genus, especially in relation to the taxonomic status of Poeciliopsis pleurospilus and P. gracilis. However, to date, no studies have been conducted to specifically address the taxonomic status of these two species. The goal of this study was to examine the taxonomic validity of P. pleurospilus and P. gracilis using genomic data (ddRADseq) in phylogenetic, population genetic, and species delimitation frameworks. Multiple analyses support the recognition of both taxa as distinct species and also permits us to revise their respective distributions. A species delimitation analysis indicates that P. pleurospilus and P. gracilis are distinct species, each of which consists of two distinct lineages that are geographically structured. Phylogenetic and population genetic analyses provide clear evidence that individuals of P. gracilis are distributed north and west of the Isthmus of Tehuantepec in both Pacific and Atlantic river systems in Mexico, whereas individuals of P. pleurospilus are distributed in both Atlantic and Pacific river systems south and east of the Isthmus of Tehuantepec, from southern Mexico to Honduras.
Morphometrics for sports mechanics: Showcasing tennis racket shape diversity
Authors: Grant Robyn A. , Taraborrelli Luca , Allen Tom
Published: January 2022

Tennis racket design has changed from its conception in 1874. While we know that modern tennis rackets are lighter and have larger heads than their wooden predecessors, it is unknown how their gross shape has changed specifically. It is also unknown how racket shape is related to factors that influence performance, like the Transverse and Polar moments of inertia. The aim of this study was to quantify how tennis racket shape has changed over time, with a view to furthering our understanding of how such developments have influenced the game. Two-dimensional morphometric analysis was applied to silhouettes extracted from photographs of 514 rackets dating from 1874 to 2017. A principal component analysis was conducted on silhouette outlines, to allow racket shape to be summarised. The rackets were grouped by age and material for further analysis. Principal Component 1 accounted for 87% of the variation in racket shape. A pairwise Pearson’s correlation test indicated that head width and length were both strongly correlated to Principal Component 1 (r = 0.916 & r = 0.801, p-values<0.001). Principal Component 1 was also correlated to the Polar (r = 0.862, p<0.001) and Transverse (r = -0.506, p<0.001) moments of inertia. Racket age and material had a medium (p<0.001, η2p = 0.074) and small (p = 0.015, η2p = 0.017) effect on Principal Component 1, respectively. Mean racket shapes were also generated from the morphometric analyses for the material and age groupings, and we consider how these shape changes may have influenced performance and injury risk. These mean shape groupings could support the development of models, such as finite element analysis, for predicting how historical developments in tennis equipment have affected performance and injury risk.
User concerns regarding information sharing on social networking sites: The user’s perspective in the context of national culture

Published: January 2022

Information sharing via social networking systems (SNS) is a common practice among academics, as well as others, that brings substantial benefits. At the same time, privacy concerns are widespread among SNS users, which may tend to inhibit their maximising the benefit from using the systems. This paper investigates the proposition that SNS user attitudes and behaviour are affected by privacy concerns, and that the effects are subject to significant cultural factors. A broad assessment of the literature provides the context for the study. Working in the context of Saudi Arabia, we apply a mixed-methods approach beginning with in-depth interviews, exposing in detail a range of views and concerns about privacy and SNS use, also allowing us to identify three key factors that bear on SNS usage and users’ concerns. Analysis of these factors in the light of the “theory of reasoned action” derives a structural model predicting several hypotheses relating the factors and users’ attitudes and behaviour. We assess the model through development of a questionnaire, administered to a large pool of academic participants, that allows us to examine how the model responds in general, and via multigroup partial least squares analyses, differentially to gender and to culturally distinct (Arab vs. non-Arab) constituents of the participant group. Results show good support for the hypotheses and clear gender and culture effects. Picking up issues from the interviews, discussion focuses on users’ views about SNS providers’ privacy policies and their inadequacy regarding culturally specific ethical concerns. We argue that these views may reflect different regulatory environments in combination with other cultural factors.

Objectives

We aimed to explore the synergistic combination of a topologically invariant Betti number (BN)-based signature and a biomarker for the accurate prediction of symptomatic (grade ≥2) radiation-induced pneumonitis (RP+) before stereotactic ablative radiotherapy (SABR) for lung cancer.

Methods

A total of 272 SABR cases with early-stage non-small cell lung cancer were chosen for this study. The occurrence of RP+ was predicted using a support vector machine (SVM) model trained with the combined features of the BN-based signature extracted from planning computed tomography (pCT) images and a pretreatment biomarker, serum Krebs von den Lungen-6 (BN+KL-6 model). In all, 242 (20 RP+ and 222 RP–(grade 1)) and 30 cases (8 RP+ and 22 RP–) were used for training and testing the model, respectively. The BN-based features were extracted from BN maps that characterize topologically invariant heterogeneous traits of potential RP+ lung regions on pCT images by applying histogram- and texture-based feature calculations to the maps. The SVM models were built to predict RP+ patients with a BN signature that was constructed based on the least absolute shrinkage and selection operator logistic regression model. The evaluation of the prediction models was performed based on the area under the receiver operating characteristic curves (AUCs) and accuracy in the test. The performance of the BN+KL-6 model was compared to the performance based on the BN, conventional original pCT, and wavelet decomposition (WD) models.

Results

The test AUCs obtained for the BN+KL-6, BN, pCT, and WD models were 0.825, 0.807, 0.642, and 0.545, respectively. The accuracies of the BN+KL-6, BN, pCT, and WD models were found to be 0.724, 0.708, 0.591, and 0.534, respectively.

Conclusion

This study demonstrated the comprehensive performance of the BN+KL-6 model for the prediction of potential RP+ patients before SABR for lung cancer.
Borderscape: Forced Syrian Migration and New Spatial Practices in Lebanon
Authors: Trovato Maria Gabriella
Published: January 2022

This article reports on my investigation of the borderscape conditions of displaced Syrians living in Lebanon, undertaken between 2015 and 2020. I conducted mapping exercises in two Lebanese districts: the Beka’a, with one of the highest percentages of persons living in informal tented settlements, recorded as up to 38 per cent of the population in 2017; and Saida, on the southern Lebanese coast, where an unfinished building was allocated as housing for close to 170 Syrian families. This article identifies, interprets, and illustrates ‘boundaries’ at these sites as a system of spaces, activities, and exchanges practiced between the inside and the outside of informal settlements in Lebanon. By acknowledging the heterogeneity and agency of research on forced migrants, this study on borders and borderscaping actions presents the finding that the displaced communities have created residential typologies in order to relate to the land, after nine years of protracted presence in Lebanon. More than 1.5 million displaced Syrians have reshaped the physical and socio-cultural organization of the land they occupy. Migration has remade the morphological organization of this land by generating new geographical patterns that are characterized by the materialities and enactments of borderscape practices.
Language in a pandemic: A multimodal analysis of social media representation of COVID-19
Authors: Adebomi Oluwayemisi Olusola
Published: January 2022

Since COVID-19 was declared a pandemic by the World Health Organization on 11 March 2020, it has become a source of worry across countries within the global space. It has posed not only a health challenge but also an economic and a linguistic burden. Linguistic burden because many efforts are being made by stakeholders to appropriately represent or codify the manifestations of the disease in unambiguous and understandable terms. Hence, one of the major platforms where COVID-19 has been variously represented is the social media. This study, therefore, focuses on a multimodal analysis of the representation of the COVID-19 pandemic on two social media platforms: Facebook and WhatsApp. The study adopts Kress’s social semiotic model as theoretical framework. This model explains the meaning affordances of verbal and non-verbal semiotic resources. It examines communicators’ intentions and makes meanings through multiple semiotic modes. This model is adopted because it offers a sociological perspective to the interpretation of visual texts. Twenty-five semiotic resources comprising memes and flash headlines, which were purposively sourced from Facebook and WhatsApp over a period of twelve weeks between April and July 2020, were analysed in the study. The data were subjected to both pictorial and simple descriptive linguistic analysis. The study reveals that COVID-19 memes extend economic and social concerns in Nigeria. The semiotic resources expose social problems such as poverty, insecurity and inequality in the Nigerian society which pose a threat to strict adherence to safety measures; and establish the manifestation of religion and gender issues in COVID-19 debates. Furthermore, it provides informative-cum-instructional functions in the fight against COVID-19. The study suggests that the deployment of appropriate linguistic and extralinguistic codes could guarantee effective and targeted public health enlightenment on COVID-19.
Pandemic politics and Africa: Examining discourses of Afrophobia in the news media
Authors: Workneh Téwodros W.
Published: January 2022

In addition to the devastating loss of lives, the harm caused by the COVID-19 pandemic to individuals and communities around the world has caused seismic disruptions in economic, social and interpersonal relationships. The pandemic has affected international diplomatic relations as well by amplifying existing geopolitical tensions. By situating discourses of Africa and Africans within global ferments of pandemic politics, this study interrogates how Africa and its peoples were invoked in global media. Drawing from postcolonial theory and conceptual propositions of Afrophobia, the study uses multimodal discourse analysis to critically examine news stories that engaged with two phenomena: controversies regarding the African director-general of the World Health Organization (WHO) and xenophobic treatment of Africans in China. Findings indicate elements of Afrophobia were evident in the Trump Administration’s and US conservative media outlets’ engagement with WHO. Additionally, the study showed the mainstreaming of non-western Afrophobia through the example of the xenophobic treatment of Africans in China. It concludes by proposing a contextual, intersectional and critical geopolitical analytical optics for a more robust understanding of the global Black experience.

The Family Reunion as a turning point in T. S. Eliot’s Verse Drama: Analysis and Suggestions for Translation
Authors: Carbajosa Palmero Natalia
Published: January 2022

T. S. Eliot wrote The Family Reunion (1939) while he composed the Four Quartets, twelve years after his conversion to Anglo-Catholicism in 1927. The play erects a bridge between the author’s early stage productions (Sweeney Agonistes, The Rock and Murder in the Cathedral) and the later society plays (The Cocktail Party, The Confidential Clerk and The Elder Statesman). Moreover, in his 1951 essay “Poetry and Drama,” Eliot delves into the strengths and weaknesses of The Family Reunion and links this play with his own experiments with a “conversational line” which introduces popular theatrical conventions wrapped in the patterns of poetry that may appeal to theatre-goers. This paper deals with Eliot’s proposals for verse drama present in an incipient form in The Family Reunion, and explores the possible ways of translating these resources into Spanish. It focuses on Eliot’s own explanations in “Poetry and Drama” about the way in which to adapt blank verse to the stage. Furthermore, this essay explores metrical concepts such as stress and caesura and applies them to wider aspects concerning dramatic patterns and inner/outer voice in characters.
The Beatles in Spain: The Contribution of Beat Music and Ye-yés to the (Subtle) Musical, Cultural and Political Openness of General Franco’s Regime in the 1960s
Authors: Ruiz Mas José
Published: January 2022

From the late 1950s and throughout the 1960s, the impact of American twist and rock’n’roll and British beat music, the Eurovision Song Contest, the considerable growth of the national record industry, the number of radio stations and the (still timid) deployment of nationwide TV gave rise in Spain to the development of the ye-yé fashion amongst the young Spanish population. This was accompanied by the development of a mild feeling of rebellion and critical spirit against the traditional conservative/Catholic status quo and the conventional mores of the previous generation. Indeed, from 1964-65 onwards dozens of Beatle-like bands imitated the Beatles’ rhythms, language, image, poses, fashion and song lyrics. The two live performances of the Beatles in Madrid and Barcelona in 1965 disseminated their popularity even further in Franco’s Spain. English became the lingua franca of modernity, of international tourism and of the new musical genres. In this Anglophile context, Beatlemania was to exert a relatively gentle influence on the social and political Spanish scenario of the decade and contributed to preparing the path to the country’s democratization in the late 1970s.

Published: January 2022

Background and Aim: The search and development of disinfectants is promising worldwide. However, there are currently no international regulations governing the testing and registration of germicidal agents. Moreover, the number of safety requirements for disinfectants for human, animal, and environmental health has increased. This research aimed to evaluate the prospects of using a collection of bacteriophages for disinfectant purposes.

Materials and Methods: The objects of research were bacteriophages isolated from a total of 129 environmental samples obtained from seven sources in and around livestock buildings: (1) Feed residues from feeders and automatic drinkers; (2) washouts from floors, walls, and posts; (3) soil from underneath floors; (4) bedding; (5) sewage; (6) ponds; and (7) soil from paddocks. The corresponding strains were used as indicator test cultures for bacteriophages. The authors employed the following methods to work with bacteriophages: (a) Bacteriophage isolation methods, (b) the Appelman method (i.e., serial dilutions), (c) the Grazia method (i.e., agar layers), (d) phage titration on solid media, and (e) the bacterial phagotyping method.

Results: The results of the analysis on the bacteria of the Enterobacteriaceae family isolated 11 bacteriophages; one bacteriophage is specific to Pseudomonas aeruginosa, and another one is specific to Brucella abortus. The results also indicate that all bacteriophage strains of the Enterobacteriaceae family demonstrate lysis at a pH of 7.0. In addition, this polyphage lyses all strains of sensitive bacterial cultures. The optimum temperature for the cultivation of bacteriophages is 35°C. While using electron microscopy to study the consortium of bacteriophages, clearly distinguishable virions of bacteriophages were found in the microscope field of view.

Conclusion: The main parameters for the production of polyphages include the ratio of the bacteriophage and its corresponding bacteriophage-sensitive culture, the pH of the cultivation medium, and the cultivation time of the bacteriophage system as well as the sensitive bacterium. With regard to the aforementioned parameters, the results indicate that the average value for all bacteriophages is 1:2, and the average cultivation medium pH is 7.0 for all bacteriophages. The average cultivation time for all bacteriophages is 18-24 h.
Forest fires have long-term effects on the composition of vascular plants and bryophytes in Scots pine forests of hemiboreal Estonia

Published: January 2022

Since fire frequency is expected to increase globally due to climate change, it is important to understand its effects on forest ecosystems. We studied the long-term patterns in species diversity, cover and composition of vascular plants and bryophytes after forest fire and the site-related factors behind them. Research was carried out in northwestern Estonia, using a chronosequence of Scots pine ( L.) stands, located on nutrient poor sandy soils, where fires had occurred 12, 23, 38, 69, 80 and 183 years ago. In every stand three 100 m vegetation plots were established to collect floristic and environmental information. The effects on floristic characteristics of time since fire, light, and soil variables were evaluated with linear mixed models, followed by backward variable selection. Compositional variation was analysed with non-metric multidimensional scaling, Multi-response Permutation Procedures, and Indicator Species Analysis. Altogether, 31 vascular plant and 39 bryophyte species were found in vegetation plots. The cover of the vascular plant and bryophyte layers increased with a longer time since fire. Soil and light variables impacted the richness of several vascular plant and bryophyte groups, whereas only the richness of liverworts and dwarf-shrubs correlated with time since fire. Considerable compositional differences were observed in vascular plant and bryophyte assemblages between recently vs. long-time ago burned stands. To conclude, time since fire significantly impacted compositional patterns of vascular plants and bryophytes in pine forests on nutrient poor soils, although time-related trends in species richness were less evident.Pinus sylvestris2

EDUCAÇÃO EM GÊNERO E SEXUALIDADE: UM DIREITO CONSTITUCIONAL
Authors: De Mendonça Amanda , Moura Fernanda , Aquino Renata
Published: January 2022

Este texto parte da concepção de que gênero e sexualidade são partes integrantes do direito à educação estabelecido constitucionalmente no Brasil. Essa premissa é norteadora para as reflexões propostas em relação aos conflitos recentes envolvendo a abordagem destas temáticas nas escolas. Desta forma, entre os objetivos principais deste trabalho estão a exposição sobre os mecanismos legais que o país possui para tratar estes temas explícita e sistematicamente na educação, bem como a análise acerca do silêncio da escola em relação à educação em gênero e sexualidade, que vem ocorrendo a despeito da existência destes dispositivos legais. Para isso, realizou-se levantamento bibliográfico, em diálogo com referenciais teóricos sobre pânico moral e papel social da educação. Constatou-se que a não abordagem destas temáticas na escola configuram uma série de violações ao direito à educação.

O método inclui a revisão de literatura de um corpus de textos políticos sobre a temática, a realização de entrevistas que possibilitem a análise por meio de amostras de relatos captados que possibilitem colocar em primeiro plano, debates e posicionamentos frente às demandas e disputas pela reeducação das relações étnico-raciais na universidade. A análise revela ainda que, políticas públicas educacionais tenhma sido implemtadas no campo educacional brasileiro, existe demandas da comunidade acadêmica, em especial de universitários negros, por mundanças de culturas acadêmicas, curriculares e epsitemológicas na universidade.
MILITARIZAÇÃO DAS ESCOLAS E AVANÇO REACIONÁRIO: UMA PERSPECTIVA DE GÊNERO
Authors: Bortolini Alexandre
Published: January 2022

Este ensaio parte do diálogo com pesquisas que se dedicam ao estudo da socialização militar, do militarismo enquanto cultura e agente político e da expansão da militarização como política educacional para apontar como a transposição em escala de uma “pedagogia militar” para as redes de ensino, articulada à expansão do militarismo no sistema político com a chegada da extrema-direita ao poder, contribui para a reinstalação de regimes masculinistas ao investir na somatização de noções generificadas de poder no processo de produção de “cidadãos” disciplinados, passíveis a formas autoritárias de governo.
EDUCAÇÃO DE JOVENS E ADULTOS E INTERSECCIONALIDADE: MULHERES NEGRAS E IDOSAS, TRABALHADORAS E ESTUDANTES
Authors: Bastos Ludimila , Eiterer Carmem
Published: January 2022

O texto apresenta análise de dados produzidos no âmbito de pesquisa de doutoramento. A pesquisa de natureza qualitativa apoia-se em entrevistas semi-estruturadas. As autoras que dão suporte as análises são principalmente Hirata (2010), Collins (2019), Bairros (1995).Discute-se a interseccionalidade como ferramenta analítica essencial para compreender as especificidades da educanda matriculada nesta modalidade de ensino. Considera-se especialmente os desafios colocados pela atuação no mundo do trabalho à partir de ocupações pouco especializadas como a de empregada doméstica. Constata-se que os atravessamentos sociais colocam estas sujeitas em situações de assimetrias de poder que se mostram obstáculos a sua frequência à escola.

DISCURSO DE ÓDIO E REPRESENTAÇÕES DE CORPOS DE MULHERES GORDAS NO YOUTUBE
Authors: Dias Kamyla Stanieski , Ripoll Daniela
Published: January 2022

Este artigo teve como objetivo analisar os discursos de ódio em comentários nos vídeos dos canais de YouTube “Tá Querida” e “Alexandrismos”. Ambos são protagonizados por mulheres gordas que tratam sobre o movimento de autoaceitação corporal intitulado body positive. Buscamos também identificar quais as representações de mulher gorda que são produzidas a partir de tais comentários. Para tanto, foi considerado o campo teórico dos Estudos Culturais em Educação, com os conceitos de Pedagogias Culturais (SILVA, 2010; CAMOZZATO, 2012; ANDRADE, 2016) e de Representação (HALL, 2016), tendo como metodologias a Etnografia Virtual (HINE, 2004) e a Análise Cultural (MORAES, 2016). Foi possível identificar discurso de ódio explícito a partir de expressões machistas e gordofóbicas direcionadas às YouTubers, bem como violência de gênero e discursos antifeministas. Já a representação predominante foi da gorda animalesca e nojenta, fazendo parte dos discursos de ódio predominantes.

Neste artigo analisamos as nuances relativas à identidade moral e expressão de gênero e sexualidades por meio de desenhos artísticos produzidos por adolescentes e jovens estudantes do Ensino Médio. Nosso objetivo é compreender as representações identitárias de reprodução e/ou imaginação criadora através dos desenhos, tendo como contexto social e político o campo de disputas entre movimentos feministas e contrassexuais e grupos conservadores em defesa da família tradicional e dos desejos cis-heteropatriarcais. Assim, a partir dos resultados do projeto de extensão “Arte de Caderno”, que reuniu trabalhos de estudantes de escolas públicas de diferentes regiões do Brasil, analisamos a produção de desenhos destacando expressões identitárias e corporais como parte do entendimento de adolescentes e jovens sobre os valores morais discutidos na atualidade. Portanto, apesar de a maioria dos desenhos reproduzir os valores hegemônicos de corporalidades e expressões identitárias binárias, outros suscitam a expressão criativa de representações identitárias dissidentes.
A POTÊNCIA DA REPRESENTATIVIDADE DE UMA ARIEL NEGRA: A CORPOREIDADE NEGRA COMO TERRITÓRIOS DE DESCONSTRUÇÃO DO RACISMO
Authors: Pereira Tavares Olívia
Published: January 2022

No entrelaçamento de estudos culturais pós-estruturalistas e decoloniais, esta pesquisa partiu da repercussão da divulgação do elenco da releitura em live-action da clássica animação A pequena Sereia (1989). O anúncio que a princesa sereia dos sete mares, Ariel, ganharia vida pela interpretação da artista negra Halle Bailey causou reações no público, tanto de apoio a escolha dos estúdios Disney, quanto manifestações de racismo. Para pensar sobre esta corporeidade protagonista nas telas, foi realizado o mapeamento de jornais, revistas e blogs onlines, artigos que versassem sobre a Ariel negra. Operando com conceitos de representação e negritude, argumento que este corpo negro ressignifica a personagem sereia-princesa-protagonista, podendo ser visto como território de potência de representatividade e desconstrução do racismo.

PALAVRAS-CHAVE: Ariel negra. Corporeidade negra. Racismo. Representatividade.
O DISCURSO DE ÓDIO EM TEMPOS DE PÓS-VERDADE:
Authors: Roslindo Paranhos William
Published: January 2022

Tempos de pós-verdade. Tempos em que o ódio é incutido no discurso e torna-se verdade. Este é o panorama que vivenciamos no Brasil de 2021 e que atinge todas as pessoas que nele vivem (mesmo aquelas que não percebem). As identidades dissidentes do padrão cisheteronormativo, por sua vez, são atacadas de forma ainda mais expressiva, junto de outras minorias, haja vista serem compreendidas como aquelas que vão contra à natureza ou à norma estabelecida. O presente artigo objetiva trazer reflexões e problematizações acerca do cenário atual baseando-se em uma autoetnografia desenhada sobre uma situação vivida pela pessoa autora. Verificou-se que a disseminação de ódio está banalizada mas que, mesmo ao utilizar de práticas violentas, ainda não é compreendido pelas pessoas como tal, o que, por si só, surge como uma grande barreira ao desenvolvimento de um trabalho pedagógico que opere em prol da educação cidadã, pela diversidade e não opressora.

Published: January 2022

It is impossible to implement very tasks by diver, because of complexity of underwater environment and high pressure in the deep sea. These tasks can just be done by a vehicle that includes all special requirements such as: high maneuverability, precise controllability, and especially hovering capability. Underwater robots are integral parts of the industry and marine science. The application of the underwater vehicles has increased with the development of the activities in deep sea. This paper presents a special Hovering type Autonomous Underwater Vehicle (HAUV) for underwater missions. To provide the most suitable and efficient formation of vehicle thrusters for reduction of complexity of control strategies and control of the most degrees of freedom, in this paper, a new thrusters' configuration is investigated, in terms of number of the thrusters, position and the thrust direction of the thrusters. The state feedback controller is designed according to the linear dynamic model and then applied to the non-linear model to validate the controller performance. Designed controller consists of three controllers: horizontal plane controller, vertical plane controller and surge controller. The last controller is developed to control the forward speed. For examination of the system behavior in presence of environmental disturbance and hydrodynamic coefficients uncertainty, the robustness of controller is also investigated.

Purpose: This study compared the diagnostic performance of the Ovarian-Adnexal Reporting and Data System (O-RADS), the Risk of Malignancy Index 4 (RMI4), the International Ovarian of Tumor Analysis Logistic Regression Model 2 (IOTA LR2), and the IOTA Simple Rules (IOTA SR) in predicting the malignancy of adnexal masses (AMs).Methods: This retrospective study included 575 women with AMs between 2017 and 2020. All clinical messages, ultrasound images, and pathological findings were collected. Two senior doctors (group I) and two junior doctors (group II) used the four systems to classify AMs. The postoperative pathological diagnosis was used as the gold standard to evaluate the diagnostic efficiency. A receiver operating characteristic curve was used to test the diagnostic performance. The interrater agreement between the two groups was tested using kappa values.Results: Of all 592 AMs, 447 (75.5%) were benign, 123 (20.8%) were malignant, and 22 (3.7%) were borderline. The intergroup consistency test yielded kappa values of 0.71, 0.92, 0.68, and 0.77 for the O-RADS, RMI4, IOTA LR2, and IOTA SR, respectively. To predict malignant lesions, the areas under the curve of the O-RADS, RMI4, IOTA LR2, and IOTA SR systems were 0.90, 0.89, 0.90, and 0.86 for group I and 0.89, 0.87, 0.88, and 0.84 for group II, respectively. The O-RADS had the highest sensitivity (91.0% in group I and 84.8% in group II).Conclusion: The four diagnostic systems could compensate for junior doctors’ inexperience in predicting malignant adnexal lesions. The O-RADS performed best and showed the highest sensitivity.
