Laboratory Evaluation on Interlayer Shear Bonding and Characterization of Microsurfacings
Authors: Raab Christiane , Partl Manfred N. , Besson Clément
Published: September 2022

Initiated by research on microsurfacings conducted in the Task Group TG 2 of the International Union of Laboratories and Experts in Construction Materials, Systems and Structures RILEM TC-280 CBE, “Multiphase Characterisation of Cold Bitumen Emulsion Materials,” the interlayer shear bonding of microsurfacings on asphalt and concrete layers was investigated in the laboratory. The paper presents interlayer bonding test results conducted at the Swiss Federal Laboratories for Materials science and Technology, Empa, thus analyzing the influence of bitumen emulsion and aggregate type on the interlayer bonding strength as well as material and surface condition of the underlying layer. The results showed that not only the type, but also the combination of bitumen emulsion and aggregate type greatly influences workability, behavior, and interlayer bond strength of microsurfacings. Additionally, curing time and the surface characteristic of the bottom layer should not be neglected.
Large-Scale Mapping of Vocalization-Related Activity in the Functionally Diverse Nuclei in Rat Posterior Brainstem
Authors: Concha-Miranda Miguel , Tang Wei , Hartmann Konstantin , Brecht Michael
Published: September 2022

The identity and location of vocalization pattern generating (VPG) circuits in mammals is debated. Based on physiological experiments, investigators suggested anterior brainstem circuits in the reticular formation, and anatomic evidence suggested the nucleus retroambiguus (NRA) in the posterior brainstem, or combinations of these sites as the putative mammalian VPG. Additionally, vocalization loudness is a critical factor in acoustic communication. However, many of the underlying neuronal mechanisms are still unknown. Here, we evoked calls by stimulation of the periaqueductal gray in anesthetized male rats, performed a large-scale mapping of vocalization-related activity using the activity marker c-fos, and high-density recordings of brainstem circuits using Neuropixels probes. Both c-fosexpression and recording of vocalization-related activity point to a participation of the NRA in vocalization. More important, among our recorded structures, we found that the NRA is the only brainstem area showing a strong correlation between unit activity and call intensity. In addition, we observed functionally diverse patterns of vocalization-related activity in a set of regions around NRA. Dorsal to NRA, we observed activity specific to the beginning and end of vocalizations in the posterior level of the medullary reticular nucleus, dorsal part, whereas medial and lateral to the NRA, we observed activity related to call initiation. No clear vocalization-related activity was observed at anterior brainstem sites. Our findings suggest a set of functionally heterogeneous regions around the NRA contribute to vocal pattern generation in rats.

SIGNIFICANCE STATEMENTVocalization patterns are shaped in the mammalian brainstem, but the identity and location of the circuits involved is debated. Additionally, the neuronal mechanisms of vocal intensity control are still unknown. This study consisted of a large-scale mapping of brainstem vocalization circuits based on the activity marker c-fosand high-density recordings with Neuropixels probes. The results confirm the role of nucleus retroambiguus in call production and point to a key role of neurons in this nucleus in loudness control. Dorsal to the nucleus retroambiguus and in the posterior medulla, the authors identify neurons with activity specific to the beginning and end of vocalizations. The results point to specific neural dials for various aspects of rat vocalization control in the posterior brainstem.
Twenty Queers of Madame Satã
Authors: Guaraná Bruno
Published: September 2022

FQ contributing editor Bruno Guaraná reviews the significance of the Brazilian director Karim Aïnouz’s groundbreaking Madame Satã on the occasion of the film’s 20th anniversary. Guaraná argues that Madame Satã was a film ahead of its time. While in dialogue with queer theory and queer cinema contemporaneous to it—placing it squarely within a global queer film canon—it also anticipated now-current notions of transgressive representations of nonbinary identities in Brazilian cinema. To think about Madame Satã in its original context thus means also recognizing the quantitative and qualitative leaps in media representation of queerness and blackness since its release.
The Status of the Close-Up in the Age of the Selfie
Authors: Betancourt Manuel
Published: September 2022

FQ columnist Manuel Betancourt ponders the power of the cinematic close-up in an era when the screened face is a ubiquitous presence on phones in selfies, front-facing videos, and Zoom grids alike. Taking Roland Barthes and Argentine writer Manuel Puig’s reverence for the faces of the silver screen sirens of Classical Hollywood as his starting point, Betancourt discusses the focus on the face in two recent films: the Mexican film Dos estaciones (Juan Pablo González, 2022) and the Chilean film Vendrá la muerte y tendrá tus ojos (Death Will Come and Shall Have Your Eyes, José Luis Torres Leiva, 2019). Although they have little in common thematically or aesthetically, both films share a focus on older queer female protagonists along with the visual grammar of the face, allowing Betancourt to appreciate the power of the close-up anew.

Published: September 2022

O presente trabalho tem como objetivo discutir o atual panorama da perícia criminal no Brasil. Apresenta um breve histórico desta função, bem como a sua evolução ao longo da história, alcançando a situação dos órgãos periciais na atualidade. Para tanto, analisou-se os Institutos Periciais diante da conjuntura legal vigente no país, para entender como se encontra os profissionais e os respectivos órgãos no sistema jurídico. Observou-se que o principal diploma legal a nortear a atividade da perícia criminal é o Código de Processo Penal Brasileiro, que indica as principais funções dos peritos oficiais e de forma geral os tipos de perícias, assim como a Lei 12.030 de 2009, que traz o rol taxativo de peritos oficiais previstos no sistema legal brasileiro. Ficou evidente que a perícia criminal necessita de uma padronização, pois, o atual quadro aponta para uma grande diversidade de formas de organização, de nomenclaturas e de enquadramento no sistema de segurança pública estadual. Foi discutida a Proposta de Emenda à Constituição, número 117 de 2015, que tem como principal escopo separar a perícia oficial de natureza criminal das polícias civis e federal e instituir a perícia criminal como órgão de segurança pública, incluindo esta no artigo 144 da Constituição Federal de 1988. Por fim, explana-se sobre a alternativa dos órgãos periciais serem incluídos no título IV, capítulo IV, onde se encontram as Funções Essenciais à Justiça.
Estimating design values for two-pin moment resisting dowel joints with lower tolerance limit approach
Authors: Uysal Mesut , Haviarova Eva
Published: September 2022

The lower tolerance limits (LTLs) for two-pin moment-resisting dowel joints, constructed of red oak and white oak, were estimated. Dowel joints are widely used in furniture manufacturing, especially for tables and chairs. Despite numerous studies to determine the strength capacities of dowel joints, their design values have not been established. For this purpose, T-shaped edgewise dowel joints were constructed to determine their ultimate failure load capacity levels. In tolerance analysis, the k-tolerance factor changes depending on sample sizes and confidence/proportion levels. Therefore, sample sizes were determined using a modified Faulkenberry-Week method for a univariate normally distributed data set created for a pilot study, which had 30 specimens. At least 215 specimens were required to make tolerance analyses at the 99/99 confidence/proportion level. Accordingly, 220 specimens were constructed. The LTL values were obtained at the 75/75, 90/75, 75/90, 90/90, 95/90, 90/95, 95/95, 99/95, 95/99, and 99/99 confidence/proportion levels to estimate reasonable design values. The results of the study indicated that the LTL method provides a sound design value estimate for dowel joints used in furniture frames.

Hegel e a liberdade social: uma abordagem a partir de Honneth
Authors: Lima Francisco Jozivan Guedes de
Published: September 2022

Neste artigo eu pretendo apresentar a abordagem de Honneth acerca da liberdade social em Hegel do ponto de vista da eticidade. A pesquisa se concentra na Filosofia do Direito de Hegel e no Direito da Liberdade de Honneth enquanto dois pilares principais de análise. Em um primeiro momento, eu esboço alguns elementos da liberdade social como um terceiro tipo de liberdade pensada como alternativa aos modelos negativo e reflexivo; em um segundo momento proponho aportes metodológicos da liberdade social a partir da reconstrução normativa em oposição às “versões kantianas da justiça”; em um terceiro momento apresento uma proposta de “componentes normativo-conceituais” da liberdade social de Hegel a partir da abordagem honnethiana. Na minha análise são três componentes fundamentais: o pressuposto ontológico da cossubjetividade; a tessitura dos processos sociais de reconhecimento mútuo; o componente institucional da vida ética. A tese central subjacente a esta reconstrução é que o indivíduo só vivencia a sua liberdade completa e plena nas relações sociais no interior de instituições justas. Sem isso, a liberdade padece de um déficit de eticidade.

Este trabalho é parte de uma pesquisa do grupo PROMOT - Processos Motivacionais em Contextos Educativos que trata sobre a adaptação inicial de docentes ao Ensino Remoto Emergencial, instaurado devido à pandemia de COVID-19 no Brasil. A coleta de dados se deu através de um formulário no Google Forms, ao qual 202 professores responderam. Os dados foram analisados por meio da metodologia de Análise de Conteúdo (BARDIN, 2011). Como resultado, com relação às influências do Ensino Remoto Emergencial no desenvolvimento dos estudantes, os professores destacam o desenvolvimento da autonomia, a valorização da escola e algumas consequências negativas, como prejuízo pedagógico e acentuação de desigualdades educacionais. No que se refere às estratégias do momento atual que continuarão a ser aplicadas no futuro, os professores apostam no uso das tecnologias digitais e na manutenção de relações mais estreitas entre escolas e famílias. Já com relação a como imaginavam que seria o retorno às aulas presenciais, os professores se abstiveram de responder ou manifestaram pessimismo.

Authors: Ramírez Barrantes Juan Carlos , Quesada Rojas Francisco Javier
Published: September 2022

The aim of this in vitro study was to evaluate the biomechanical and chemical behavior of various bioactive materials in class II MOD restorations. Forty-eight standardized class II MOD cavities were prepared in sound extracted human molar teeth.  The specimens were divided into four groups according to the restorative material: Group 1 (Filtek™ Z350 XT), Group 2 (Biodentine™ as a liner, and then restored with Filtek™ Z350 XT), Group 3 (Cention N™), and Group 4 (Activa™ Bioactive-Restorative). The samples were tested for fracture resistance by subjecting them to a compressive load in a Universal testing Machine. The failure modes of each specimen were evaluated. The alkalinizing potential and calcium ion release of the materials were measured. SEM-EDAX analyses were also performed for all materials. Data were analyzed using ANOVA and post hoc Tukey test (p<0.05). Group 1 showed the higher fracture resistance (p<0.05). Group 3 had greater fracture resistance values but no statistical difference from Group 4. Biodentine™ showed greater biomineralization potential. Class II MOD restorations of Group 1 displayed the higher fracture resistance; however, it was highly associated with catastrophic failure. Conversely, Biodentine™ presented a more significant bioactivity potential, and its use, as in Group 2, promoted the most favorable failure mode.

Published: September 2022

Background and aims

Perfectionism is correlated with the occurrence of exercise dependence. We aim to reveal the role of functional connectivity (FC) between gray matter (GM) and white matter (WM) networks in the association between perfectionism and exercise dependence.

Methods

In this cross-sectional study, one hundred ten participants with exercise dependence underwent behavioral evaluation and resting-state functional magnetic resonance imaging. Perfectionism and exercise dependence were quantified using the Frost Multidimensional Perfectionism Scale (FMPS) and Exercise Dependence Scale (EDS). We used a K-means clustering algorithm to identify functional GM and WM networks and obtained the FCs of the GM-GM, GM-WM, and WM-WM networks. Partial correlation and mediation analyses were performed to explore the relationships among FCs, FMPS, and EDS.

Results

We identified ten stable GM networks and nine WM networks. Of these, FCs existed between the corona radiata network (WM1) and default mode network (DMN, GM8), WM1 network and WM DMN (WM4), WM1 network and midbrain WM network (WM7), and WM4 network and inferior longitudinal fasciculus network (WM9). The WM1-GM8 and WM1-WM4 FCs were positively correlated with the EDS and negative FMPS. The mediating effects of the WM1-GM8 and WM1-WM4 FCs were established in the association between the negative dimensional FMPS and EDS.

Discussion and Conclusions

The WM1 network anatomically linked the subregions within the GM8 and WM4 networks, and WM1-GM8 and WM1-WM4 FCs mediated the association between negative dimensional FMPS and EDS. These findings indicated that DMN function might be involved in the increased risks of exercise dependence promoted by negative perfectionism.
Ionic poly(dimethylsiloxane)–silica nanocomposites: Dispersion and self-healing

Published: September 2022

Poly(dimethylsiloxane) (PDMS)-based nanocomposites have attracted increasing attention due to their inherent outstanding properties. Nevertheless, the realization of high levels of dispersion of nanosilicas in PDMS represents a challenge arising from the poor compatibility between the two components. Herein, we explore the use of ionic interactions located at the interface between silica and a PDMS matrix by combining anionic sulfonate-functionalized silica and cationic ammonium-functionalized PDMS. A library of ionic PDMS nanocomposites was synthesized and characterized to highlight the impact of charge location, density, and molecular weight of ionic PDMS polymers on the dispersion of nanosilicas and the resulting mechanical reinforcement. The use of reversible ionic interactions at the interface of nanoparticles–polymer matrix enables the healing of scratches applied to the surface of the nanocomposites. Molecular dynamics simulations were used to estimate the survival probability of ionic cross-links between nanoparticles and the polymer matrix, revealing a dependence on polymer charge density.

Impact statement

Poly(dimethylsiloxane) (PDMS) has been widely used in diverse applications due to its inherent attractive and multifunctional properties including optical transparency, high flexibility, and biocompatibility. The combination of such properties in a single polymer matrix has paved the way toward a wide range of applications in sensors, electronics, and biomedical devices. As a liquid at room temperature, the cross-linking of the PDMS turns the system into a mechanically stable elastomer for several applications. Nanofillers have served as a reinforcing agent to design PDMS nanocomposites. However, due to significant incompatibility between silica and the PDMS matrix, the dispersion of nanosilica fillers has been challenging. One of the existing strategies to improve nanoparticle dispersion consists of grafting oppositely charged ionic functional groups to the nanoparticle surface and the polymer matrix, respectively, creating nanoparticle ionic materials. Here, this approach has been explored further to improve the dispersion of nanosilicas in a PDMS matrix. The designed ionic PDMS nanocomposites exhibit self-healing properties due to the reversible nature of ionic interactions. The developed synthetic approach can be transferred to other kinds of inorganic nanoparticles dispersed in a PDMS matrix, where dispersion at the nanometer scale is a prerequisite for specific applications such as encapsulants for light-emitting diodes (LEDs).

ABSTRACT: Varronia curassavica is a Brazilian native medicinal species. Among the critical points influencing the phytochemical quality of bioactive compounds is the spacing between plants, harvest and post-harvest. This research aimed evaluated the influence of plant distance, harvest season, and leaves drying temperature on the yield and phytochemical quality of V. curassavica essential oil. The organic cultivation was carried out in 2018/2019 using 0.6 x 1.0; 0.8 x 1.0; 1.0 x 1.0; 1.0 x 1.6 m spacing between plants. The macro and micronutrient contents of the leaves were evaluated and no considerable changes were observed. In 2018 the harvest was performed in summer, autumn, and winter, and the harvested leaves were immediately submitted to the drying process at 40 °C. In 2019 the harvest was performed in winter, and the leaves were submitted to the drying process at 40, 50, and 60 °C. The essential oil was extracted by hydrodistillation and the chemical constituents were evaluated using CG-MS. The essential oil yield was significantly higher in winter and used 0.8 x 1.0 m and 1.0 x 1.0 m spacing between plants. The alpha-humulene content remained within the recommended standards at all analyzed temperatures. Although, the drying temperatures tested did not compromise the alpha-humulene content, the increasing temperature caused a reduction in the essential oil yield. Thus, it is recommended for the organic cultivation of V. currassavica the spacing of 0.8 x 1.0 m and 1.0 m x 1.0 m, and the drying of its leaves between 40 and 50 °C to earn the highest essential oil yield and phytochemical quality.

Published: September 2022

ABSTRACT: The present study evaluated the growth of the species Mytella guyanensis and Mytella strigata on ropes suspended in Amazon Macrotidal Mangrove Coast. The mussels were farmed at a density of 840 ind. m-1 of rope, with the same shell height (mm) and live weight (g) for both species. The experiment was entirely randomized, with two treatments and 15 repetitions. Significant differences were reported regarding the growth (shell height and live weight) between the species (P>0.05). The daily growth rate was greater for M. guyanensis than for M. strigata. At the end of the cultivation cycle, only 451 ± 46 (59.9%) of M. guyanensis individuals reached commercial size per meter of rope compared to 670 ± 73 (89.3%) of M. strigata individuals. Survival rates were similar. Salinity and temperature increased progressively throughout the experiment with the reduction in rainfall and were within the range considered ideal for these species. In conclusion, the farming of both species of mussels was viable under estuarine conditions influenced by macrotides, with satisfactory survival rates and daily growth (shell height and weight).

Published: September 2022

ABSTRACT: We evaluated under field conditions the toxicity of insecticides previously identified as harmful in laboratory and semifield bioassays on the parasitoid Trichogramma pretiosum (Hymenoptera: Trichogrammatidae). The experiments were conducted during the 2019/20 and 2020/21 harvests in rice fields. Following the recommendations of the International Organization for Biological and Integrated Control (IOBC), four insecticides were applied in 64 m2 experimental plots. Subsequently, T. pretiosum was released inundatively. To verify parasitism rates, at 1, 2, 4 and 6 days after release (DAR) of the parasitoids, eggs from the host Ephestia kuehniella (Lepidoptera: Pyralidae) were offered. After determining the number of parasitized eggs, the data were grouped into a reduction coefficient (Ex) to provide a single result for the effects of the insecticides on parasitoid. For both the 2019/20 and 2020/21 evaluated crops, it was found that at 2 DAR, the highest parasitism rates occurred. In contrast, in 6 DAR, no parasitism rates were observed. Lambda-cyhalothrin, thiamethoxam, and zeta-cypermethrin were classified as moderately harmful; thiamethoxam + lambda-cyhalothrin was classified as harmful. Following IOBC guidelines, the toxicity of these products under field conditions is lower than that obtained in the laboratory or semi-field for the T. pretiosum. However, these insecticides should be avoided, or used at times that do not coincide with the release or presence of the parasitoid in the field.

Published: September 2022

ABSTRACT: This study evaluated different meta-analytical approaches tousing citric and ascorbic acids in the performance of nursery piglets. The study included 24 publications between 1985 and 2018 (mode 1998), totaling 4215 nursery piglets. The Higgins index indicated high heterogeneity (98.5%) among the studies concerning citric acid (96.9%) and ascorbic acid (91.4%). In variances and forest plot analysis, using citric and ascorbic acids and their analogs was no significant effect (P > 0.05) on piglet weight gain. In the meta-analysis approach proposed by LOVATTO et al. (2007) and SAUVANT et al. (2008), there was no significant effect (P > 0.05) of the addition of citric and ascorbic acids on piglet performance. Numerically, was observed an increased ADG (Δ > 0) related to acids (supplemented over control treatments) in 59.7% (ascorbic acid) and 46.6% (citric acid) of the ADG comparisons. The effect of ascorbic supplementation on the respective control treatment of the overall nursery period was on average 0.98%, 1.07%, and -1.3% for ADFI, ADG, and FCR, respectively. Citric acid supplementation to the respective control treatment of the overall nursery period was on average 1.67%, 4.40%, and -2.29% for ADFI, ADG, and FCR. Adding citric and ascorbic acids in diets for nursery piglets does not alter performance regardless of the meta-analysis method used.

Published: September 2022

Resumo A discriminação percebida é um importante produtor de estresse e trauma social e pode ter efeitos negativos sobre a saúde física e mental das pessoas expostas a ela. Este estudo visa analisar a associação direta e indireta entre discriminação percebida e prática de atividade física, mediada por transtornos mentais comuns de adolescentes. Trata-se de pesquisa transversal, com 2.484 adolescentes (18 e 19 anos) de uma coorte de São Luís, Maranhão. Modelos de equações estruturais foram utilizados para verificar o efeito direto da discriminação percebida sobre a atividade física (AF) e seu efeito indireto mediado pelos Transtornos Mentais Comuns (TMC). O potencial do sexo como variável modificadora de efeitos também foi testado. A discriminação percebida esteve associada a maiores níveis de AF nas mulheres (CP - Coeficiente padronizado direto =0,105, p-valor=0,005), e associada a menor AF por via indireta pelos TMC entre homens (CPindireto =-0,024, p-valor=0,017) e mulheres (CPindireto =-0,024, p-valor=0,015). Os achados mostram que nesta população de adolescentes houve associação entre discriminação percebida e AF, demonstrando que seus efeitos podem alterar comportamentos de saúde e o sexo pode modificar a relação entre essas variáveis.

Published: September 2022

Abstract Perceived discrimination is a major producer of stress and social trauma and can have negative effects on the physical and mental health of those exposed to it. This study aims to analyze the direct and indirect association between perceived discrimination and physical activity, mediated by common mental disorders in adolescents. This is a cross-sectional study with 2,484 adolescents (aged 18 and 19 years old) from a cohort in São Luís, Maranhão. Structural equation models were used to verify the direct effect of perceived discrimination on physical activity (PA) and its indirect effect mediated by common mental disorders (CMD). The potential of sex to act as an effect-modifying variable was also tested. Discrimination was associated with higher levels of PA in women (SC - Standardized Coefficient direct =0.105, p-value=0.005), and indirectly associated with lower PA via CMT among men (SCindirect =-0.024, p-value=0.017) and women (SCindirect =-0.024, p-value=0.015). Our findings show the association between perceived discrimination and PA in this population of adolescents, attesting that its effects can alter health behaviors and that gender can modify the relation between these variables.

Published: September 2022

Resumo A Profilaxia Pré-Exposição ao HIV (PrEP) tem renovado o otimismo no controle da epidemia de HIV, não obstante seu contínuo crescimento entre os homens que fazem sexo com homens (HSH). A popularidade dos aplicativos de encontro afetivo-sexual e plataformas de mídias digitais na troca de informações e experiências sobre PrEP nas redes sociais de pares é reconhecida, embora sejam escassos estudos sobre contextos, motivações e alcance em termos da prevenção ao HIV. O artigo objetiva compreender a dinâmica das redes de pares virtuais e presenciais entre HSH para a decisão de usar PrEP, sua revelação e publicização. Estudo qualitativo com uso de entrevistas semiestruturadas com 48 usuários de PrEP de cinco cidades brasileiras. A maioria dos entrevistados compartilha informações e experiências sobre PrEP nas redes sociais de pares, contudo sua publicização revela tensões decorrentes da permanência de estigmas associados à homossexualidade e ao HIV. O protagonismo na revelação do uso da PrEP expressa engajamento em conquistar novos usuários. A relevância das redes sociais de pares no compartilhamento de experiências e informações sobre a PrEP tem potencial para a diversificação do público-alvo, ampliação e democratização da cobertura de PrEP no país.
HIV Pre-Exposure Prophylaxis (PrEP) among men who have sex with men: peer communication, engagement and social networks
Authors: Santos Lorruan Alves dos , Grangeiro Alexandre , Couto Marcia Thereza
Published: September 2022

Abstract HIV Pre-Exposure Prophylaxis (PrEP) has renewed optimism in controlling the HIV epidemic, despite its continued growth among men who have sex with men (MSM). The popularity of dating-sexual dating apps and digital media platforms in exchanging information and experiences about PrEP on peer social networks is recognized. However, studies on contexts, motivations, and scope in HIV prevention are scarce. The article aims to understand the dynamics of virtual and face-to-face peer networks among MSM for the decision to use PrEP, its disclosure, and publicity. Qualitative study using semi-structured interviews with 48 PrEP users from five Brazilian cities. Most interviewees share information and experiences about PrEP in peer social networks. However, its publication reveals tensions arising from the permanence of stigmas associated with homosexuality and HIV. The protagonism in exposing the use of PrEP expresses commitment to attracting new users. The relevance of peer social networks in sharing experiences and information about PrEP has the potential to diversify the target audience and expand and democratize PrEP coverage in the country.

Authors: Moreira Martha Cristina Nunes
Published: September 2022

Resumo Refletimos sobre as configurações da parentalidade atípica no campo da deficiência e cronicidade. A categoria êmica atípico compõe com esses campos. As simbólicas associativas são exploradas com uma etnografia nas redes digitais e entrevistas com ativistas. Indicamos processos em curso na luta anticapacitista que dialogam com agendas da Política como Cuidado. Concluímos que a “parentalidade ativista atípica” opera com significados e aprendizados de viver e conviver com a deficiência/cronicidade/raridade na proximidade com um filho/filha, não se restringindo a rupturas biográficas.
Configurations of atypical parenting activism in disability and chronicity
Authors: Moreira Martha Cristina Nunes
Published: September 2022

Abstract This article aims to reflect on the configurations of atypical parenting in the field of disability and chronicity. The atypical emic category composes with these fields. Associative symbolicities are explored with an ethnography in social media and interviews with activists. We indicate ongoing processes in the anticapacitist struggle that dialogue with agendas of Politics as Care. We conclude that “atypical activist parenting” operates with meanings and learnings of living and being familiar with disability/chronicity/rarity in proximity to a son/daughter, not being restricted to biographical ruptures.
Masculinidades em construção, corpos em (re)construção: desejos, contradições e ambiguidades de homens trans no processo transexualizador
Authors: Ribeiro Cláudia Regina , Ahmad Andrea Felizardo , Dantas Beatriz Selles , Lemos Adriana
Published: September 2022

Resumo O artigo traz os resultados de uma pesquisa sobre as estratégias, expectativas e desejos de 28 homens transexuais na construção das suas masculinidades e reconstrução de seus corpos por meio da hormonização cruzada. A pesquisa qualitativa foi realizada em um ambulatório do processo transexualizador de um município da região metropolitana do Rio de Janeiro. Para a construção dos dados, foram utilizadas a entrevista semiestruturada e a observação participante, empreendidas entre os meses de novembro de 2019 e janeiro de 2020. A análise de conteúdo orientou a análise das falas, das quais emergiram as categorias que foram discutidas à luz dos conceitos de gênero, transexualidade e masculinidades, além de referências de estudos sobre raça/cor em suas articulações com a saúde. Os dados revelaram desejos, contradições e ambiguidades no que diz respeito à construção da masculinidade e à (re)construção de corpos mais adequados a ela; evidenciaram o desejo pelo padrão corporal de masculinidade que seria conquistado por meio da hormonização e de cirurgias, e a cor negra surgiu como uma importante marca de desigualdade. Concluímos que, mesmo refutando muitos traços do modelo de masculinidade, esses homens desejam adentrar esse mundo e confundir-se na multidão como homens, vivenciando a masculinidade mais plena.

Published: September 2022

Resumo O objetivo deste artigo é caracterizar a violência física por parceiro íntimo sofrida por mulheres adultas atendidas nos serviços públicos de urgência e emergência do Brasil. Estudo transversal utilizando dados do VIVA Inquérito 2017. Foram calculados as frequências e os intervalos de confiança das características da vítima, da violência e do agressor. As associações das características foram identificadas por meio da análise de correspondência simples (ACS). A maioria das mulheres atendidas se autodeclarou da raça/cor da pele negra (70,2%) e foi vítima de agressor do sexo masculino (96,3%). A maioria das violências ocorreu em residência (71,1%) por meio de força corporal (74,1%). Na ACS, destaca-se a associação entre a faixa etária de 40 a 59 anos, escolaridade de até 08 anos de estudo, consumo de álcool pela vítima e violência por meio de armas (perfil 2); e a associação da faixa etária de 18 a 24 anos, raça/cor da pele negra, ausência de atividade remunerada, agressão em via pública e lesões de maior gravidade (perfil 4). Existem diferentes perfis de VPI para mulheres em diferentes contextos. O enfrentamento à VPI necessita de Políticas Públicas que considerem essas diferenças na construção de ações que foquem as mulheres e os perpetradores da violência.
Physical violence against women by an intimate partner: analysis of VIVA Survey 2017
Authors: Vasconcelos Nádia Machado de , Andrade Fabiana Martins Dias de , Gomes Crizian Saar , Bernal Regina Tomie Ivata , Malta Deborah Carvalho
Published: September 2022

Abstract This article aims to characterize physical violence by an intimate partner suffered by adult women treated in public urgency and emergency services in Brazil. This is a cross-sectional study using data from the VIVA Survey 2017. The proportions and 95% confidence intervals of the characteristics of the victim, violence, and perpetrator were calculated. The associations of characteristics were identified through Simple Correspondence Analysis (SCA). More than half of the assisted women self-declared their race/skin color to be black (70.2%) and were the victim of a male perpetrator (96.3%). Most violence occurred at home (71.1%) through physical force (74.1%). In the SCA, an association was found among the variables of age group, between 40 and 59 years; level of education, up to 08 years of study; alcohol consumption by the victim; and violence by weapons (Profile 2). An association was also found among the variables of age group, between 18 and 24 years; black race/skin color; lack of paid work; aggression on public places; and more serious injuries (Profile 4). There are different intimate partner violence (IPV) profiles for women in different contexts. Confronting IPV requires Public Policies that consider these differences in the construction of actions that focus on women and perpetrators of violence.
Physical frailty, activity limitation and mortality in older Brazilians: longitudinal findings from FIBRA-BH study (2009-2019)
Authors: Venturini Claudia , Moreira Bruno de Souza , Silva Silvia Lanziotti Azevedo da , Sampaio Rosana Ferreira
Published: September 2022

Abstract The aim was to investigate the longitudinal association between physical frailty and change in the profile of limitation to perform basic and instrumental activities of daily living (BADL and IADL) and mortality in a 10-year period in Brazilian community-dwelling older people. A longitudinal study was conducted with data from the Frailty in Brazilian Older People (FIBRA) study, 2009-2019. Physical frailty was categorized into vulnerability (pre-frail and frail) and robustness (non-frail). The generalized estimating equation and the Cox proportional hazards models were used in the data analysis. Out of 200 older people evaluated in 2009 (moment 1), 139 were located in 2019 (moment 2). Of these, 102 were interviewed and 37 deaths were recorded. The chance of vulnerable older people at moment 1 being dependent on performing BADL at moment 2 was 4.19-fold the chance of robust older people. For IADL, the chance of vulnerable older people at moment 1 being dependent at moment 2 was 3.12-fold the chance of robust older people. Cox’s analysis showed that the risk of death among vulnerable older people was 2.50-fold that among robust older people. The results reinforce the importance of monitoring and early intervention to prevent frailty, and the limitation to performing activities of daily living and death among Brazilian older people.

Published: September 2022

Resumo O objetivo deste estudo foi avaliar a tendência temporal dos benefícios previdenciários concedidos pelo Instituto Nacional do Seguro Social a mulheres por câncer de mama. Foi realizado um estudo de tendência temporal das taxas de incidência dos auxílios por incapacidade temporária de espécie previdenciária concedidos por câncer de mama em mulheres entre 2007 e 2018 no Brasil, utilizando o Sistema Único de Informações de Benefícios e a base de dados abertos da Previdência Social. As análises de tendência foram realizadas através de regressão segmentada joinpoint. As taxas de incidência dos benefícios ajustadas por idade apresentaram estabilidade entre 2007 e 2015, seguida de elevação anual de 6,7% de 2015 a 2018. Houve aumento anual médio de 3,4% do número de benefícios concedidos a mulheres entre 20 e 49 anos, sendo mais evidente entre 2015 e 2018, com elevação de 10,4% ao ano. Este estudo demonstrou a importância do câncer de mama como causa de afastamento do trabalho em mulheres, com acometimento crescente das faixas etárias mais jovens e economicamente ativas, o que reforça a necessidade de abordagem precoce do Programa de Reabilitação Profissional da Previdência Social para a readaptação destas trabalhadoras em suas atividades ou a reinserção no mercado de trabalho.

Published: September 2022

Resumo Após 13 anos da publicação da Política Nacional da Saúde Integral da População Negra (PNSIPN), o preenchimento do quesito raça/cor na identificação de pacientes permanece um desafio. Autores têm se debruçado sobre a necessidade de integrar os conhecimentos da ciência da implementação às políticas públicas. O objetivo deste artigo é descrever e analisar a implementação da coleta do quesito raça/cor feito pelos profissionais responsáveis pelo registro dos pacientes num hospital universitário do município de São Paulo. Estudo exploratório e descritivo, estruturado a partir de três constructos do Consolidated Framework for Implementation Research (CFIR): intervenção, cenário interno e características dos indivíduos. Resultados: a maioria dos registros do quesito raça/cor na instituição observada é feita por heteroidentificação. A partir dos constructos do CFIR, são identificados aspectos apontados como obstáculos ou facilitadores. A implementação da coleta do quesito raça/cor por autodeclaração, como previsto na PNSIPN e na Portaria 344/2017, ainda é incipiente e depende de mudanças, sobretudo organizacionais, que favoreçam sua efetivação.
