Dynein Light Chain DLC-1 Facilitates the Function of the Germline Cell Fate Regulator GLD-1 in Caenorhabditis elegans
Authors: Ellenbecker Mary , Osterli Emily , Wang Xiaobo , Day Nicholas J , Baumgarten Ella , Hickey Benjamin , Voronina Ekaterina
Published: December 2018

Developmental transitions of germ cells are often regulated at the level of post-transcriptional control of gene expression. In the Caenorhabditis elegans germline, stem and progenitor cells exit the proliferative phase and enter meiotic differentiation to form gametes essential for fertility. The RNA binding protein GLD-1 is a cell fate regulator that promotes meiosis and germ cell differentiation during development by binding to and repressing translation of target messenger RNAs. Here, we discovered that some GLD-1 functions are promoted by binding to DLC-1, a small protein that functions as an allosteric regulator of multisubunit protein complexes. We found that DLC-1 is required to regulate a subset of GLD-1 target messenger RNAs and that DLC-1 binding GLD-1 prevents ectopic germ cell proliferation and facilitates gametogenesis in vivo. Additionally, our results reveal a new requirement for GLD-1 in the events of oogenesis leading to ovulation. DLC-1 contributes to GLD-1 function independent of its role as a light chain component of the dynein motor. Instead, we propose that DLC-1 promotes assembly of GLD-1 with other binding partners, which facilitates formation of regulatory ribonucleoprotein complexes and may direct GLD-1 target messenger RNA selectivity.

Published: December 2018

El género Opisthonema sustenta la pesquería de sardina en Costa Rica. Esta investigación se orientó hacia la evaluación poblacional del stock explotable de esta pesquería en el Golfo de Nicoya. Las muestras mensuales fueron recolectadas desde junio del 2007 hasta mayo del 2008. Se determinó el patrón de reproducción de O. libertate y se estimaron los parámetros de crecimiento de las curvas en longitud del modelo de von Bertalanffy para O. libertate y O. medirastre. Con base en el índice gonadosomático, O. libertate desova intensamente durante la época más calurosa del año, entre febrero y mayo. La talla de primera madurez (TPM50%) fue de 18.68 cm de LT. La ecuación de crecimiento de von Bertalanffy estimada para O. libertate fue: Lt= 25.9 [1–exp–1.03(t+0.13)] y para O. medirastre: Lt= 32.0 [1–exp–1.10(t+0.15)]. El reclutamiento máximo de la pesquería de O. libertate ocurre entre septiembre y noviembre. Esta especie muestra un índice de explotación (E) de 0.65 y O. medirastre de 0.55. Se nota una mejoría en el E comparado con estimaciones anteriores. Se recomienda como medida de manejo para esta pesquería ajustar la época de veda y no incrementar el esfuerzo pesquero.The Opisthonema genus supports the sardine fishery in Costa Rica. This research was directed to population assessment of the exploitable stock of this fishery in the Golfo of Nicoya. Monthly samples were collected since June, 2007 until May, 2008. The reproductive pattern of O. libertate were determined and growth parameters of curves in the length of O. libertate and O. medirastre were estimated using the von Bertalanffy model.. Based on the gonadosomatic index, O. libertate spawn intensively during the hottest time of the year, between February and May. The size at first maturity (SFM50%) was 18.68 cm T.L.

Published: December 2018

This article was migrated. The article was marked as recommended. Introduction:Globally, medical schools are trying to widen access and to increase the diversity of their student body to be more representative of the population and to meet the future heath care needs of society. Selection methods must not disadvantage the applicants from priority groups. In Memorial University’s Faculty of Medicine, rural applicants and applicants from low socioeconomic status are priority groups. Methods:Since 2013, Memorial University has used a combination of traditional panel interviews and MMIs to interview candidates for medical school. We wondered whether applicants who participate in this medical school interview process perform differently on the MMIs compared to the traditional panel interview process and whether performance differs on either of the two interview processes based on age, sex, origin(urban or rural), or socioeconomic status.Results:The mean score on the traditional panel interview was higher than that on the MMI. Females scored higher than males on both the traditional panel interview and the MMI.  Applicants aged 22 and younger performed worse on both the traditional panel interview and the MMI than the other age groups. Neighborhood socioeconomic status, and urban/rural living status were not significantly related with applicants’ performance on the traditional panel interview or MMI.Discussion:The type of interview is not disadvantaging applicants from Memorial University’s priority areas.

Authors: Fink Ryan , Kuhn Catherine , Yanez N. David , Taekman Jeffrey
Published: December 2018

This article was migrated. The article was not marked as recommended. Background: Grit, defined as perseverance and passion for long-term goals, is associated with high levels of success in multiple domains but has only been minimally studied in the medical fields. Aims: This study examined whether higher levels of grit are associated with measures of anesthesiology resident performance – standardized test scores and faculty evaluations. Methods: 23 graduated anesthesiology residents volunteered to participate in the study. Participants completed the Grit Survey via an online interface. The program director provided performance data to a neutral data manager, who de-identified the data prior to analysis. Results: Correlation estimates between standardized test scores and grit ranged between -0.12 and 0.31 (not statistically significant at the one percent level of significance; p values ranging from 0.16 to 0.85). Correlation estimates between PGY-4 faculty evaluations and grit scores ranged from 0.43 to 0.49, but were not statistically significant. There may be a trend towards significance, as p-values ranged from 0.021 to 0.044. Conclusion: This pilot study showed a trend toward higher grit being associated with higher overall faculty evaluation of resident performance in their final year of training. This finding was non-significant and thus should be considered preliminary. There was no significant association between grit and performance on standardized tests.

Published: December 2018

ABSTRACT Objective: Evaluate the impact of anxiety and depression on morbidity and mortality of patients with acute coronary syndrome. Method: Retrospective cohort study, with follow-up of two years, conducted with 94 patients. The morbidity and mortality (readmission, myocardial revascularization, and death) was evaluated immediately after discharge and after one and two years. Anxiety and depression were evaluated by the State-Trait Anxiety Inventory and by Beck’s Depression Inventory. The Kaplan-Meier estimator and the Logrank test were used. The significance level adopted was 0.05. Results: We observed that 76.6% of the patients did not present symptoms of depression or had mild signs, while 78.8% had low to moderate anxiety. The symptoms of depression and anxiety were not related to morbidity (need for MR p=0.098 and 0.56, respectively; readmission p=0.962 and 0.369, respectively) and mortality (p=0.434 and 0.077, respectively). Conclusion: No relationship was found between levels of anxiety and depression with the morbidity and mortality of patients.

S. A. Fábrica Votorantim e o setor têxtil paulista (1918-1939): os caminhos que levaram o grupo da falência à liderança industrial
Authors: Silva Gustavo Pereira da , Costa Armando João Dalla
Published: December 2018

Resumo: A compreensão dos grupos econômicos brasileiros apresenta uma lacuna, sobretudo, no entendimento de como esses grupos se formaram na primeira metade do século XX. O Grupo Votorantim, oitavo maior grupo brasileiro em 2007, surgiu no final do século XIX, mas ganhou sua definição empresarial em 1918, quando foi adquirido pelo empresário Antonio Pereira Ignácio. Nas décadas de 1920 e 1930, o principal empreendimento da Sociedade Anônima Fábrica Votorantim (SAFV) era a fábrica têxtil, localizada em Sorocaba (SP), próxima dos outros empreendimentos do grupo (ferrovia, cal e cimento, venda de terrenos, usina hidrelétrica). Analisando fontes primárias da SAFV (balanços patrimoniais, demonstrações de lucros e perdas, relatórios de diretoria) e os levantamentos sobre a indústria paulista, evidenciamos sua evolução ao posto de principal empresa têxtil paulista na década de 1930, progresso apoiado em três fatores: sua constituição como um grupo econômico, sua administração familiar e suas ligações com o setor financeiro paulista.
Incorporando o risco soberano no desenho operacional do regime de metas de inflação
Authors: Marques Junior Karlo , Correia Fernando Motta
Published: December 2018

Resumo: O objetivo deste artigo é analisar os mecanismos de coordenação entre políticas monetária e fiscal, em uma economia com regime monetário do tipo metas de inflação, que permitam acomodar choques exógenos e manter tal economia em um equilíbrio estável em um ambiente em que o risco de default contribui para a instabilidade da dívida e da taxa de juros de política monetária. É desenvolvida uma estrutura analítica no intuito de capturar os mecanismos de transmissão do risco soberano e seus efeitos na definição de funções-reações para a autoridade monetária e fiscal. Para isso, utilizou-se um modelo de equações diferenciais simultâneas de primeira ordem em que se analisou o equilíbrio intertemporal do modelo e sua estabilidade. Os principais resultados mostram que na hipótese de regras fiscais, com a imposição de um superávit primário, a autoridade monetária deve apresentar um peso maior dos desvios da inflação em relação à meta de inflação, de modo que um controle fiscal é desejado para que a economia não seja muito vulnerável a choques de risco soberano. Em uma configuração em que não há regra fiscal, é necessário que a autoridade monetária acomode os choques do risco soberano com aumentos na taxa básica de juros.
Productive efficiency and the future of regional disparities in Brazil
Authors: Schettini Daniela , Azzoni Carlos Roberto
Published: December 2018

Abstract: We use Stochastic Production Frontiers to estimate the recent levels and the evolution of productive efficiency across regions in Brazil. Results are available for agriculture, industry and services, as well as for total production. We observe a substantive efficiency growth exhibited by agriculture at the national level, which is counterbalanced by the poor performance of services. The regional results show that efficiency levels still replicate, in general, the regional inequality that marked the country’s history through decades. However, the efficiency growth reveals new signs of convergence among states, especially for industry, with effects on the aggregate production. This indicates that inequality trends in productive efficiency may be starting to change.

Published: December 2018

Abstract In the identification process, the foramen magnum has shown controversial results in sex estimation. The present study aimed to analyze the morphometric variables of the foramen magnum in Brazilian adult cranium for sex estimation. The sample was composed of 100 craniums (53 males and 47 females) from the documented collection of the Institute of Teaching and Research in Forensic Sciences. The protocol measurement was constituted of two linear measurements: maximum length of the foramen magnum and maximum breadth of the foramen magnum and two formulas to calculate the area, method one (M1) and method two (M2). Descriptive statistics showed statistically significant differences between sex (p<0.05) for all variables. The univariate discriminant functions showed an accuracy between 56.0-62.0%, and the multivariate analysis showed a percentage of accuracy between 60.0-65.0%, the greatest accuracy was found combining the two linear measurements with M1(71.7%), even after cross-validation (66%). Receiver Operating Characteristic (ROC) curve analysis showed that M2 is the best parameter for estimating sex (AUC=0.693). A reference table for Brazilians using the foramen magnum parameters was developed based on the results of the ROC curve analysis. In conclusion, the foramen magnum should be used with caution to estimate sex in forensic cases of fragmentary craniums, due to the limited accuracy.

Abstract This study aimed to evaluate the physicochemical properties of a calcium silicate-based sealer (Sealer Plus BC; MK Life, Porto Alegre, Brazil) compared with an epoxy-resin sealer (AH Plus; Dentsply DeTrey GmbH, Konstanz, Germany). Initial and final setting time was assessed based on ISO 6876:2012 and ASTM C266:03. Calcium ion release and pH were evaluated by filling polyethylene tubes with sealers and then immersing them in 10 mL of deionized water. Following experimental periods of 1, 24, 72 and 168 hours, the samples were measured regarding pH and calcium ion release with a pH meter and a colorimetric spectrophotometer, respectively. The flow was examined based on ISO 6876:2012. Rings of 10 mm in diameter with 1 mm thickness were prepared to analyze the radiopacity (ISO 6876:2012 and ADA n.57) and solubility (ISO 6876:2012). The data were analyzed by variance analysis, Student-T and Tukey tests (p<0.05). The calcium ion release and pH values were significantly higher for the Sealer Plus BC compared with the AH Plus (p<0.05). Lower setting time, flow and radiopacity were observed for the bioceramic sealer than for AH Plus (p<0.05). Sealer Plus BC exhibited higher solubility compared with AH Plus (p<0.05). Sealer Plus BC showed physicochemical properties as setting time, pH, calcium release, flow, and radiopacity following the required standards, but higher solubility than the minimum values required by ISO 6876:2012.

Published: December 2018

Abstract The occurrence of caries lesions adjacent to restorations is a serious problem in Dentistry. Therefore, new antimicrobial restorative materials could help to prevent recurrent carious lesions. This study evaluated the effect of a new glass ionomer cement (Ion Z) on the viability of a microcosm biofilm and on the development of enamel demineralization. Enamel samples were filled with the following materials (n=9): A) Ion-Z (FGM Ltda); B) Maxxion R (FGM Ltda); C) Ketac Fil Plus (3M ESPE) and D) no restoration (control). The samples were then exposed to human saliva mixed with McBain saliva (1:50) containing 0.2% sucrose for 14 days. The live and dead bacteria were quantified by fluorescence using a confocal laser-scanning microscope. The enamel demineralization was analyzed using transverse microradiography (TMR). The data were submitted to ANOVA/Tukey or Kruskal-Wallis/Dunn test (p<0.05). Ion Z induced a higher percentage of dead bacteria (60.96±12.0%) compared to the other groups (Maxxion R: 39.8±6.7%, Ketac Fil Plus: 43.7±9.71% and control 46.3±9.5%). All materials significantly reduced the average mineral loss compared to control (Ion-Z 25.0±4.2%vol, Maxxion R 23.4±8.0%vol, Ketac Fil Plus 30.7±7.7 and control 41.2±6.6%vol). Ion-Z was the only material able to significantly improve the mineral content at the surface layer (Zmax: 63.5±18.2%vol) compared to control (38.9±11.3%vol). Ion-Z shows antimicrobial potential, but its anti-caries effect was similar to the other materials, under this model.

Published: December 2018

ABSTRACT: Hippeastrum spp. are herbaceous species belonging to the family Amaryllidaceae, widely marketed worldwide as indoor plants. Aiming to characterize chemically and physically and to compare five substrates in acclimatization, micropropagated seedlings of Hippeastrum reticulatum var. striatifolium (Herb), with an average of four roots, two leaves and bulbs with a 4.7mm diameter, were transplanted to 50-cell polyethylene trays each containing the following substrates: T1 - vermiculite, T2 - carbonized rice husk (CRH), T3 - commercial (peat + vermiculite + CRH), T4 - coconut fiber, and T5 - composted Pinus bark. After transplantation, the trays were kept for 17 days at a greenhouse with intermittent irrigation by nebulization, and 80 days at a greenhouse on a bench with intermittent irrigation by capillarity. The experimental design was randomized blocks with seven replications and ten seedlings per plot. The acclimatization of seedlings was efficient for the substrates tested despite the differences verified by chemical and physical characterization. The mean survival rate was 96%. However, seedlings acclimatized in the T5 substrate showed a qualitative improvement due to a higher formation of roots, leaves and fresh matter.
Relationship between root exudation of organic carbon and physiological variables of irrigated rice cultivars
Authors: Moscôso Janielly Silva Costa , Silva Leandro Souza da , Tarouco Camila Peligrinotti , Nicoloso Fernando Teixeira , Severo Fabiane Figueiredo , Aita Natália Tobin , Prigol Luís Henrique Ferreira
Published: December 2018

ABSTRACT: Rhizospheric carbon resulting from root exudation is one of the substrates used by the soil microbiota, and reflects methane (CH4) emissions in anoxic environments such as irrigated rice cultivation. With the increase of the photosynthetic capacity of the plant in the reproductive period, there is greater accumulation of biomass which, in turn, increases the rate of root exudation. However, genotypic variations in the physiological aspects of rice plants may be related to the amount of root exudates. Ten cultivars of irrigated rice were evaluated for the exudation rate of total organic carbon (EXRToc), shoot dry matter (SDM), and physiological variables related to photosynthesis during the full flowering (blooming) period. Two experiments were conducted in the greenhouse of the Department of Soils of the UFSM (University of Santa Maria, Santa Maria, RS, Brazil) in a completely randomized experimental design. The cultivars presented significant differences in EXRToc, SDM, and all physiological variables as well as positive and significant correlations between EXRToc and physiological variables. Early cultivars were more inefficient in the physiological variables reflecting reduced values of EXRToc and SDM whereas medium-cycle cultivars were more efficient with larger EXRToc and SDM reflections.
A REORGANIZAÇÃO DO TRABALHO EM RIO GRANDE-RS A PARTIR DA IMPLEMENTAÇÃO DA INDÚSTRIA NAVAL

Published: December 2018

RESUMO O estudo buscou entender as consequências da implementação da indústria naval na organização do trabalho na cidade de Rio Grande/RS. Para tal, propõe-se o conceito de organização do trabalho como o resultado de uma relação de forças antagônicas que, dinamizada por mecanismos de produção, organizam formas contraditórias de produzir a vida. O trabalho é entendido como fundante do ser e da práxis social, de modo que organizá-lo extrapola a mera distribuição das atividades nos locais onde ocorre a produção econômica. A partir de estudo exploratório, na cidade de Rio Grande, constatou-se que a implantação e posterior crise do polo naval provocaram alterações nas diversas dimensões da vida dos trabalhadores e da comunidade local. O investimento na indústria naval incitou a migração de trabalhadores que vislumbraram no polo naval de Rio Grande possibilidades de obter trabalho ou melhorar a renda. Agora, Rio Grande enfrenta o declínio da indústria naval que ameaça inclusive a manutenção dos estaleiros na cidade. Ao final, se considera que a forma de organização do trabalho reorganiza a vida social, tanto em nível individual quanto na comunidade como um todo e que há um predomínio do favorecimento do processo de acumulação do capital.

Authors: Nogueira Rafael Maia , Carvalho Neto Antônio Moreira de , Nunes Thiago Soares
Published: December 2018

RESUMO A atuação sindical em relação ao assédio moral no trabalho, embora tímida, tem se intensificado ao longo das últimas décadas decorrente da degradação das condições laborais e adoecimento do trabalhador, pressionado pelo atual sistema econômico e social de competitividade. O artigo objetivou investigar como o assédio moral tem sido colocado dentro dos acordos e convenções coletivas de trabalho. Trata-se de uma pesquisa qualitativa e descritiva. Os dados utilizados na pesquisa foram coletados no banco de dados do Departamento Intersindical de Estatística e Estudos Socioeconômicos (DIEESE), que consistem em 177 cláusulas específicas que versam sobre assédio moral no período compreendido entre 2011 e 2016. Para análise dos dados, foi utilizado a análise de conteúdo, de acordo com sete categorias de análise. O quantitativo de cláusulas é relativamente pequeno se considerado o universo de entidades sindicais filiadas ao Departamento, mas pode-se observar uma pequena evolução no quantitativo de cláusulas no período, que estão mais concentradas nas regiões Sul e Sudeste. Cláusulas que tratam da questão da prevenção, prescrevendo programas, palestras e outros, bem como a associação com o assédio sexual, foram as que tiveram maior frequência. Por outro lado, aquelas associadas a participação sindical e apoio a vítimas.

RESUMO O presente estudo trata sobre as características que influenciam a intenção de consumo de produtos tecnológicos vestíveis, baseado nos valores hedônicos, utilitários e de status social. O objetivo é compreender como se dá o processo de consumo dos relógios inteligentes (Apple Watch), identificando as características de compras dos usuários, dado a pouca prática tecnológica e percepção da utilidade do produto. Realizou-se uma pesquisa de campo, com a finalidade de analisar a intenção de consumo dos usuários, com aplicações de questionários abertos com imagem e características das funcionalidades do produto, nos quais os usuários podiam expressar abertamente suas opiniões para que em seguida fosse realizado a análise do conteúdo dos comentários. Os resultados obtidos apontam a existência de uma ligação entre fatores comportamentais como hedonismo, utilitarismo, status social, risco social, inveja e cobiça e sua influência quanto ao uso e consumo do relógio inteligente Apple Watch.

ABSTRACT Objectives: To evaluate the regenerative capacity of gracilis (G) and semitendinosus (ST) tendons, to examine the sensitivity and specificity of signs and symptoms in the assessment of hamstring tendons, and to assess the thickness and insertion site of regenerated tendons. Methods: Thirty sequential knees were subjected to anterior cruciate ligament reconstruction with semitendinosus and gracilis tendons. After surgery, the patients were followed up clinically with physical examination and magnetic resonance imaging (MRI). Results: Overall, 36.66% of the tendons were visible on MRI, whereas 83.33% were palpable. On MRI, the distal insertion site of the regenerated semitendinosus tendon was visible proximal to the landmark of the medial femoral condyle in 28%, at the same level in 16%, and distally in 56% of the cases. Gracilis tendon insertion was visible proximally in 36.66% of cases, at the same level in 10%, and distally in 53.33%. Eleven knees exhibited complete regeneration. Conclusion: Partial or total regeneration of the ST and G tendons was apparent on MRI. Palpation is effective for evaluating regeneration of the ST and G tendons; however, MRI is still the gold standard. ST and G tendons regenerated completely in only a small percentage of patients, limiting reuse as a graft in cases with new ligament injuries of the knee.

ABSTRACT Background: Distal radius fractures are one of the most common orthopedic injuries and appear in various patterns. Volar plate fixation is not always considered the gold standard treatment. Objective: To measure the resistance of a fragment-specific fixation assembly model obtained by plate fixation associated with different K-wire sizes. Method: In this original experimental study, novel II, axial compression of bone materials was tested. Results: In both groups, the maximum force supported by the fixation method in our study was ten times greater than the physiological load to which the wrist was subjected under physiological conditions. Discussion: In this study, we obtained encouraging results when compared to results reported in the literature. Our study showed that our bone fixating system was mechanically adequate for articular fractures of the intermediate column of the radius (Melone classification). The results were similar or superior to the results of pressure resistance and stiffness when data from the literature was used as reference. Conclusion: The proposed fixation method demonstrated adequate resistance for fixation of the intermediate column of the distal radius. Increasing K wire size caused augmented resistance of the fixation. Level of Evidence II, Prospective comparative study.

Abstratct This research aimed to investigate the reading comprehension and possible associations with self-perception of academic performance in elementary and middle school students. The study included 298 students enrolled from the 2nd to 9th grades in public schools the states of São Paulo and Parana. Two Cloze tests were collectively applied: one specific for elementary school (first stage of basic education) and another for the middle school (second stage). Results indicated that the students presented an instructional reading comprehension. It was also possible to observe statistically significant differences between Cloze score and self-perception of academic performance. In general, it can be stated that the students who presented better levels of reading comprehension are also the ones that better self-assessed. The data are discussed considering the psychoeducational implications concerning the mode of education investigated.

Abstract The relationship between parents and children and human development has been the greatest interest to Psychology because it impacts the youth’s behaviour and well being. Thus, this study aimed to investigate parental styles adopted by adolescents’ parents from a combination of responsiveness and demandingness dimensions as well as by gender and age group. 296 adolescents aged 14 to 19 years (M=16.03; DP=0.96), high school students from public and private schools in the city of Passo Fundo/RS and surrounding area participated of this study. We used a sociodemographic data questionnaire constructed for the study and Scale of Parental Responsiveness and Demandingness. The analysis revealed that there was a balance between the perception of neglectful (33.1%) e authoritative (32.7%) styles, followed by authoritarian (17.3%) and permissive (16.9%) styles. There were no statistical differences between responsiveness and demandingness and sex. The younger adolescents perceive their mothers as significantly more demanding when compared to the older ones. The same occured with the combined demandingness. The results also indicate that there were statistically significant differences in the perception of responsiveness and demandingness by age group. The findings of this study suggest further investigations, relating parental styles with other variables of influence and evidence the need of parental training for parents who adopt neglectful style.
Processos Identitários de um Grupo de Doulas: Atitudes sobre Gestantes e Médicos
Authors: Duarte Camila Nogueira Bonfim , Souza Luiz Gustavo Silva
Published: December 2018

Resumo O objetivo deste estudo foi investigar processos identitários de um grupo de cinco doulas, incluindo suas percepções sobre o próprio grupo, gestantes e médicos. Foram aplicadas entrevistas semiestruturadas, análise de conteúdo temática e, como referencial teórico, a Teoria da Identidade Social. Os resultados demonstraram a relevância do feminismo, ativismo social e movimento de humanização do parto para os processos identitários das participantes. Verificou-se que o grupo fornece apoio profissional e social, com sentimento de pertença e amizade. Discute-se que o ativismo, o grupo de trabalho e encontros regulares com gestantes são estratégias de mudança social, visando à transformação da assistência à saúde e relações de gênero. O estudo foi limitado pelo número de participantes, mas forneceu compreensão sobre tema pouco explorado. Futuras pesquisas poderão investigar práticas de doulas em articulação com o Sistema Único de Saúde brasileiro (SUS).
Invariância Fatorial e Normatização das Escalas de Sobre-Excitabilidade
Authors: Oliveira Juliana Célia de , Barbosa Altemir José Gonçalves
Published: December 2018

Resumo Este estudo teve como objetivos estabelecer normas preliminares e verificar a estrutura e invariância fatorial das Escalas de Sobre-Excitabilidade (ESE) de acordo com o sexo. Trata-se de uma medida destinada à avaliação de sobre-excitabilidade - tendência para reagir intensa e sensivelmente a estímulos nas áreas sensorial, psicomotora, imaginativa, emocional e intelectual. Participaram 1500 estudantes do ensino fundamental de cinco estados brasileiros. Análises fatoriais confirmatórias demonstraram bons índices de ajustes para os modelos testados, revelando a existência de 11 escalas. Apesar de haver diferenças quanto ao sexo nos escores médios de algumas escalas, análises fatoriais confirmatórias multigrupos indicaram a invariância fatorial da medida nos grupos masculino e feminino. A normatização preliminar foi estabelecida a partir do cálculo do percentil acumulado para os escores totais e por sexo. Esses resultados evidenciam propriedades psicométricas adequadas e constituem um avanço para a normatização das ESE.
Reconhecimento, desreconhecimento e demarcação simbólica: uma contribuição conceitual à análise do lado negativo do reconhecimento
Authors: Souza Luiz Gustavo da Cunha de
Published: December 2018

Resumo O presente artigo tem por objetivo central esboçar uma discussão teórica a respeito de relações de demarcação e hierarquização simbólicas que poderiam ser descritas por meio da categoria analítica de desreconhecimento. Este conceito, que será apresentado em relação aos recentes debates sobre a teoria do reconhecimento, conforme formulada por Axel Honneth, e sobre o lado negativo das relações de reconhecimento, visa explicitar formas de exercício do poder por meio das quais grupos privilegiados denegam a outros grupos ou indivíduos a possibilidade de participar em condições de igualdade das esferas institucionais de reconhecimento que legitimam as sociedades modernas. Neste sentido, as práticas e discursos de desreconhecimento representam uma negação intencional ou uma tentativa de solapar a aplicação dos princípios implícitos do liberalismo democrático e universalista, conforme pressuposto na tradição teórica do reconhecimento. Particular atenção será dada a dois casos de corrosão das normas implícitas de reconhecimento: em primeiro lugar, serão expostas formas de animosidade que buscam justificar estas práticas por meio do recurso à constituição de um imaginário sobre grupos diferentes, assim atribuindo a estes últimos certas características negativas; em segundo lugar, serão trabalhados alguns exemplos da tradição do pensamento social brasileiro e de um eventual aguçamento das tensões políticas e de suas consequências para as tentativas de demarcação simbólica observadas no país.
Sensibilidade ecológica e ambientalismo: uma reflexão sobre as relações humanos-natureza
Authors: Pereira Elenita Malta
Published: December 2018

Resumo Neste artigo, são abordadas diferentes dimensões presentes nas representações humanas sobre a natureza: a sensibilidade ecológica, ou seja, a manifestação dos sentimentos e percepções humanas em relação ao mundo natural, e o ambientalismo, movimento construído historicamente, de caráter global, porém plurifacetado, disperso em diversas vertentes, que se dedica à proteção e conservação do ambiente natural e humano. O objetivo é analisar a historicidade dessas dimensões, considerando alguns de seus defensores e críticos. A discussão leva, finalmente, ao entendimento da relação dos humanos com a natureza como um problema tanto histórico quanto ético-moral.
Distopias presentes, passadas e futuras: os monstros da sociedade
Authors: Talone Vittorio da Gamma
Published: December 2018

Resumo A presente resenha abarca a obra de Gregory Claeys mapeando o que chama de história natural da distopia, cujo objetivo é dar conta da passagem, na sociedade, dos medos naturais (deuses, monstros) para os medos sociais (tecnologias opressivas, totalitarismo). Analisarei como o autor busca, atentando a fatos históricos, mitos, religiões, sistemas políticos e à chamada “literatura distópica”, dar conta da dimensão comportamental-emocional e das sensações definidoras de distopias para diferentes grupos e sociedades. Com isso, serão observados não apenas cenários e obras projetadas como distópicas, mas contextos passados e presentes assim caracterizados: a tarefa é justamente alertar e educar sobre as distopias da vida real. Considerando a presente conjuntura político-socioeconômica, é um esforço que intenta forçar a conceber soluções coletivas em momentos de crescente irracionalidade e pânico.
