As luzes do século e as trevas da ignorância: intervenções da elite política e intelectual na formação dos cidadãos nas Minas Gerais regencial
Authors: Lazzarini Júlia Lopes Viana
Published: December 2020

A atuação de uma elite intelectual, que muitas vezes era também política, em relação ao alcance de suas ideias foi bastante considerável durante o período imperial. O período regencial trouxe consigo as discussões a respeito dos direitos políticos que deveriam ser cedidos a uma parcela da população brasileira, as quais se iniciaram após 1822. Algumas estratégias foram traçadas pelos poderes constituídos para contornar o problema quanto a presença das grandes massas e a ideia que se tinha sobre elas. No caso de Minas Gerais, a própria Assembleia Provincial dedicou lei que tornava obrigatória a frequência escolar dos cidadãos, possíveis futuros servidores da nação; o uso da imprensa também foi frequente, assim como a atuação dos párocos pode ter exercido papel fundamental para a disseminação dos ideais hegemônicas da elite política e intelectual vigente.

Authors: Colombo Luciléia Aparecida , Nascimento Emerson Oliveira do
Published: December 2020

Este trabalho objetiva a compreensão da trajetória da Superintendência para o Desenvolvimento do Nordeste (Sudene), desde o seu nascimento, em 1959, até as suas transformações, processadas a partir do governo militar no Brasil. Como escolha metodológica, optamos por selecionar a teoria institucionalista, especialmente centrada no institucionalismo histórico, para compreender os processos de mudança pelos quais a instituição passou. Além disso, focalizamos o papel desempenhado por Celso Furtado na condução da instituição, tanto para o seu nascimento como para a aprovação de seus planos diretores. Por fim, é importante mencionar que o pano de fundo de nossa análise é o federalismo brasileiro, cuja principal característica é a desigualdade regional observada quando analisamos a posição do Nordeste em relação ao restante do país.

ENTRE SILÊNCIOS E VIRTUALIDADES SURGEM ENCONTROS: COSTURANDO O CUIDADO DE SI E A EDUCAÇÃO DO SENSÍVEL
Authors: Bemvenuto Vitória Da Silva , De Souza Maria Ântonia Sattamini
Published: December 2020

Este relato convida à reflexão sobre a experiência vivida na pandemia instaurada pelo COVID-19, a quem chamamos “vírus do silêncio”. Por meio desta escrita, propomos um encontro entre o Cuidado de Si de Foucault, a Educação do Sensível de Duarte Jr. e os afetamentos que batem à porta da nossa casa-corpo, em tempos de quarentena. Pesquisando possibilidades de nos manter presentes e sensíveis, revisitamos esses autores e percebemos o quanto estão inseridos em nossas práticas educativas, enquanto professoras, estudantes da rede pública de ensino e pesquisadoras da relação entre corpo e educação. Assim, por meio do diálogo acreditamos que, o encontro entre o Cuidado de Si e o fomento à uma educação voltada às sensibilidades humanas, permeiam a consciência e a autonomia dos sujeitos.

Published: December 2020

Em tempos de pandemia do novo coronavírus, que provoca a COVID-19, quase todas as estruturas consolidadas do planeta foram modificadas, como por exemplo: a restrição da circulação e o fechamento de shoppings centers, escolas, academias etc. No que tange a educação, uma nova forma foi apresentada para dar continuidade ao ano letivo vigente nas escolas públicas e privadas, chamados por muitos de estudo recluso. Os usos dos artefatos tecnológicos, muitas vezes proibidos nos espaçostempos escolares, tornaram-se uma possibilidade de continuarmos tecendo conhecimentossignificações. Pretendemos mostrar neste artigo as implicações desenvolvidas em nossos novos ou outros cotidianos. Como se estabeleceram esse ‘outro lado da moeda’ quando dependemos da tecnologia, como foram as apropriações e os desafios encontrados para estudantes, pais e professores, além de compreender quais foram as práticasteorias aplicadas em um momento em que a democratização do ensino se viu profundamente afetada.

Bolsonarismo, conservadorismo e direitos humanos: analisando o papel da ideologia política como condicionante ao pleno exercício dos direitos humanos no Brasil contemporâneo | Bolsonarism, conservatism and human rights: analyzing the role of political ideology as a restriction to the full exercise of human rights in contemporary Brazil
Authors: Ramos Guilherme Antunes
Published: December 2020

O artigo problematiza a situação dos direitos humanos no Brasil em face do advento de uma ideologia conservadora que nega a universalidade que inspira ditos direitos. Argumenta-se que a ideologia política se apresenta como um embaraço à aplicabilidade dos direitos humanos na condição de direitos pretensamente universais. Para corroborar esse argumento, são analisados dois casos considerados ilustrativos da interveniência da ideologia nas novas políticas de direitos humanos durante o governo de Jair Bolsonaro, a saber, a reversão da decisão brasileira de aderir ao Pacto Global para a Migração e a instrução conferida a diplomatas e demais representantes do Brasil no exterior de defender, em foros internacionais, o entendimento de que a palavra gênero traduz tão somente o sexo biológico de um indivíduo. Trata-se de um trabalho de cunho exploratório, que aborda possíveis reveses no tocante a temas atinentes aos direitos humanos provocados pelo recrudescimento de posições conservadoras.Palavras-chave: direitos humanos; conservadorismo; governo Jair Bolsonaro.ABSTRACTThe article discusses the condition of human rights in Brazil in the face of a conservative ideology that denies the universality that characterizes such rights. It is argued that political ideology presents itself as a barrier to the applicability of human rights as understood as allegedly universal. In order to sustain this argument, two cases considered to be illustrative of ideological intervenience in the new policies directed towards human rights under the presidency of Jair Bolsonaro are analyzed, the reversal of the brazilian decision to be a part of the Global Compact for Migration and the instruction given to diplomats and other brazilian representatives abroad to sustain, in international forums, the undertanding that gender is restricted to a biological condition. It is an exploratory essay that analyzes possible setbacks related to human rights topics in Brazil, driven by the escalation of conservative positions.Keywords: human rights; conservatism; presidency of Jair Bolsonaro. Recebido em 30 jan. 2020 | Aceito em 08 jun. 2020.
Relações Internacionais e Pensamento Ocidental/Moderno-Colonial: Balanços e Perspectivas | International Relations and Western/Modern-colonial thinking: balances and perspectives
Authors: Amorim de Souza Jerfferson
Published: December 2020

A predominância do pensamento Ocidental/moderno-colonial no campo das Relações Internacionais tem despertado críticas de estudiosos vinculados ao Pensamento Decolonial e a outras matrizes de conhecimento. Este trabalho tem por objetivo apresentar uma sistematização da fundamentação filosófica-epistemológica da crítica decolonial ao pensamento moderno e sua repercussão nas Relações Internacionais e, a partir dessas contribuições, propor uma aproximação com alguns estudos que, fora do âmbito da colonialidade, discutem a predominância de um pensamento ocidental na disciplina. Como consequência da aproximação entre esses saberes diversos, apresentamos alguns balanços e perspectivas para a área: a necessidade de conexão entre epistemologia-ética-política; a reabilitação de conhecimentos e modos de conhecer não-Ocidentais sem renunciar ao método científico; uma visão não ingênua que leve em conta as questões de poder; e uma articulação entre saber e poder, teoria e política para uma práxis situada e histórica vertida à realidade internacional.Palavras-chave: Racionalidade moderna; pensamento decolonial; epistemologia. ABSTRACTThe predominance of Western / modern-colonial thought in the field of International Relations has aroused criticism from scholars linked to Decolonial Thought and other knowledge matrices. This work aims to present a systematization of the philosophical-epistemological foundation of the decolonial critique of modern thought and its repercussion in International Relations and, based on these contributions, propose an approximation with some studies that, outside the scope of coloniality, discuss the predominance of a western thought in the discipline. As a consequence of the approximation between these diverse knowledges, we present some balances and perspectives for the area: the need for a connection between epistemology-ethics-politics; the rehabilitation of non-Western knowledge and ways of knowing without giving up the scientific method; a non-naive view that takes into account issues of power; and an articulation between knowledge and power, theory and politics for a situated and historical praxis turned to the international reality.Keywords: Modern rationality; decolonial thinking; epistemology. Recebido em: 29 jul. 2020 | Aceito em:  18 nov. 2020

ESCREVO SOBRE MIM E POR NÓS: RAÇA, SOLIDÃO E AFETIVIDADE DA MULHER NEGRA RETINTA NO BRASIL.
Authors: Carvalho Lucymara Da Silva , Sanches Maria Aparecida Prazeres
Published: December 2020

A escrita desse artigo nasce da minha experiência de solidão sexo-afetiva como uma mulher negra retinta universitária, vivenciada ao longo da minha graduação em História na Universidade Estadual de Feira de Santana (UEFS-BA) entre os anos de 2014-2019. Em diálogo com estudos historiográficos, sociológicos, filosóficos e os conceitos elaborados pela teoria do Feminismo negro, objetivamos compreender e analisar como as angústias e alegrias sentidas no meu corpo podem nos capacitar a entender historicamente o processo de preterimento das mulheres negras no Brasil. Para tal, lançamos mão, do conceito de Escrevivências da escritora Conceição Evaristo, da categoria de analise Corpo-território elaborada pelo geografo Eduardo Miranda e das ponderações dos estudos de gênero e raça como metodologia adotada na tentativa de trilhar um caminho, ainda tão pouco convencional na historiografia.

Improved correction by freeform surfaces in prism spectrometer concepts
Authors: Tang Ziyao , Gross Herbert
Published: December 2020

The correction of spatial resolution and distortion in imaging spectrometer systems is of great importance due to their significant impact on efficiency and quality. In this study, we analyze the corrective power of freeforms added at different positions in various spectrometer systems for high-performance requirements. The results show that the combination of a freeform prism and a second freeform close to the image has the best correction of distortion while preserving spot size.
Fabrication of molybdenum oxide thin films with different Kerr nonlinearities and using them in random lasers
Authors: Ghasempour Ardakani Abbas , Sadeghi Niloufar
Published: December 2020

The development of random lasers (RLs) is attracting considerable interest. Here, we investigate how the nonlinear optical behaviors of scattering particles can affect the emission of RLs. In this regard, molybdenum oxide is synthesized by the electrodeposition method, and its nonlinear optical properties are measured using the Z-scan technique. Then, to study the nonlinear effects on RL emission, we insert molybdenum oxide in a conventional RL. It was observed that the emitted intensity enhanced for samples with a positive sign of nonlinear refractive index, while intensity degraded for samples with a negative refractive index. Our results show that both the sign and magnitude of the nonlinear refractive index can modify the intensity of RL emission at pump energies enough above the threshold.
Refractive index modulation in media with saturable photosensitivity
Authors: Mokhov Sergiy , Lumeau Julien
Published: December 2020

Permanent change of the refractive index of photo-thermo-refractive glass can be achieved by exposure to ultraviolet light followed by thermal development. The dependence of the change on the dosage is nonlinear because the photochemical process of photosensitivity involves saturation. With a holographic recording of Bragg gratings inside glass, a sinusoidally modulated dosage is imprinted into distorted modulation of the refractive index. We investigate this distorted modulation and derive analytical expressions for the amplitudes of its spatial harmonics.
Accumulation of Nicotinamide N-Methyltransferase (NNMT) in Cancer-associated Fibroblasts: A Potential Prognostic and Predictive Biomarker for Gastric Carcinoma
Authors: Zhang Li , Song Mengmeng , Zhang Fan , Yuan Hao , Chang Wenjun , Yu Guanyu , Niu Yongdong
Published: December 2020

Nicotinamide N-methyltransferase (NNMT), a major metabolic regulator, has been identified as a predictor of cancer prognosis in ovarian and colorectal cancers. The study aims to evaluate the significance of stromal NNMT in gastric cancer (GC). Expression of stromal NNMT in 612 GC and 92 non-malignant tissues specimens was investigated by immunohistochemistry (IHC). The association between NNMT expression and occurrence of cancer or patient outcome was further analyzed, and the factors contributing to disease prognosis were evaluated by multiple Cox models. Stromal NNMT expression was higher in the malignant tissue ( p<0.001). NNMT expression was significantly associated with GC stage ( p=0.006). Compared to stromal “NNMT-low” cases, “NNMT-high” cases has lower disease-specific survival (hazard ratio [HR], 2.356; 95% confidence interval [CI] = 1.591–3.488; p<0.001) and disease-free survival (HR = 2.265; 95% CI = 1.529–3.354; p<0.001), as observed by multivariate Cox analysis after adjusting for stromal NNMT expression with other factors such as tumor grade and size. Notably, patients with stage II NNMT-low GC might be negatively affected by adjuvant chemotherapy, but lower stromal NNMT expression predicted a more favorable prognosis for GC. Our study confirmed that stromal NNMT expression is significantly increased in GC, which predicts an unfavorable post-operative prognosis for GC:
Bridging from single to collective cell migration: A review of models and links to experiments
Authors: Buttenschön Andreas , Edelstein-Keshet Leah
Published: December 2020

Mathematical and computational models can assist in gaining an understanding of cell behavior at many levels of organization. Here, we review models in the literature that focus on eukaryotic cell motility at 3 size scales: intracellular signaling that regulates cell shape and movement, single cell motility, and collective cell behavior from a few cells to tissues. We survey recent literature to summarize distinct computational methods (phase-field, polygonal, Cellular Potts, and spherical cells). We discuss models that bridge between levels of organization, and describe levels of detail, both biochemical and geometric, included in the models. We also highlight links between models and experiments. We find that models that span the 3 levels are still in the minority.

Published: December 2020

To clarify the physical and mental conditions of children during the coronavirus disease 2019 pandemic and consequent social distancing in relation to the mental condition of their caregivers. This internet-based nationwide cross-sectional study was conducted between April 30 and May 13, 2020. The participants were 1,200 caregivers of children aged 3–14 years. Child health issues were categorized into “at least one” or “none” according to caregivers’ perception. Caregivers’ mental status was assessed using the Japanese version of the Kessler Psychological Distress Scale-6. The association between caregivers’ mental status and child health issues was analyzed using logistic regression models. Among the participants, 289 (24.1%) had moderate and 352 (29.3%) had severe mental distress and 69.8% of children in their care had health issues. The number of caregivers with mental distress was more than double that reported during the 2016 national survey. After adjusting for covariates, child health issues increased among caregivers with moderate mental distress (odds ratio 2.24, 95% confidence interval 1.59–3.16) and severe mental distress (odds ratio 3.05, 95% confidence interval 2.17–4.29) compared with caregivers with no mental distress. The results highlight parents’ psychological stress during the pandemic, suggesting the need for adequate parenting support. However, our study did not consider risk factors of caregivers’ mental distress such as socioeconomic background. There is an urgent need for further research to identify vulnerable populations and children’s needs to develop sustainable social support programs for those affected by the outbreak.

Authors: Chanda M. , Jha S. , Mukhopadhyay D. , Pandey M.
Published: December 2020

Humic acid and fulvic acid extracted from soils of cultivated areas, collected from Majitar, Darjeeling
and Pundibari cities were first isolated, purified and then characterized for the physico-chemical
properties (oxidizable organic carbon, electrical conductivity, pH, phosphorus, nitrogen, potassium,
CEC, etc.). The physico-chemical studies showed that soils were neutral to acidic but are independent
of altitude. Organic carbon, available phosphorus, nitrogen were higher with soil of Majitar city. The
total acidity, carboxylic group, phenolic -OH group were higher in fulvic acid than in humic acid.
Further, both acids were characterized by potentiometric titration, viscometric measurement, surface
tension and spectral analysis. The humification index (E4/E6) of fulvic acid was relatively higher than
humic acid. The highest molecular weight of humic acid and fulvic acid were recorded 13645.83 and
1465.54, respectively.

Published: December 2020

Averrhoa bilimbi fruit has been studied to find out a possible source of bioactive compounds against antimicrobial and cytotoxic activity. To achieve this goal, total phenolic content and total flavonoid content, antioxidant, antimicrobial and cytotoxic activities of five different fractionates such as methanolic crude, petroleum ether, chloroform, ethyl acetate and water fraction of A. bilimbi were investigated by UV-vis spectrophotometry, disc diffusion and brine shrimp lethality test methods simultaneously. Other phytochemicals viz. carbohydrate, tannins, polyphenols, glycosides, etc. were also screened out by conventional test methods concurrently. Total phenolic contents and total flavonoid contents were found to be ranging from 3.807-262.129 mg GAE g–1 and 67.848-1159.061 mg CE g–1, respectively, in all the analyzed fractions. DPPH free radical scavenging activity revealed distinctive IC50 value of 5.63 and 10.26 μg mL–1 in the chloroform and ethyl acetate extractives. Fractionates of petroleum ether and methanolic crude also presented strong cytotoxic potential with the LD50 values of 8.89 and 20.3 μg mL–1 in the brine shrimp lethality bioassay test. Petroleum ether and ethyl acetate fractions exhibited good antimicrobial activity with the zone of inhibition against Bacillus cereus (11 mm and 14 mm) and Escherichia coli (7 mm and 9 mm). Finally, it has been recommended that A. bilmbi fruit might be an effective source of bioactive compounds against antimicrobial and cytotoxic activity as well as antioxidant with potent radical scavenging activity.

Published: December 2020

Hemophagocytic lymphohistiocytosis is a syndrome characterized by excessive immune activation. Timely diagnosis can be challenging, and prompt treatment is the only hope for survival. We present an adult patient with a history of alcohol dependence, who presented with fatigue, bilateral lower extremity edema, and orange-colored urine. Clinical workup revealed abnormal liver function tests, elevated ferritin, cytopenia, and lymphadenopathy. Eventually, he was diagnosed with hemophagocytic lymphohistiocytosis. This case report encourages gastroenterologists to maintain a high index of suspicion when a patient presents with liver failure, hyperferritinemia, and cytopenia because they may be the first healthcare professionals to evaluate these patients.

Published: December 2020

Autoimmune gastritis is an inflammatory condition of the gastric mucosa. We report a 64-year-old woman with chronic abdominal pain of 3-year duration. Endoscopic and histologic evaluation revealed autoimmune pangastritis. The gastritis was partially responsive to steroids but attempts to taper failed, and the patient had no relief from mercaptopurine, adalimumab, budesonide, or hydroxychloroquine. The patient was treated with mycophenolate mofetil which resulted in resolution of symptoms. Endoscopic and histologic examination after mycophenolate therapy showed near complete resolution of active inflammation. To the best of our knowledge, this is the first report of symptomatic autoimmune gastritis successfully treated by mycophenolate mofetil.

Authors: Suk Ladislav , Števanka Kamil , Petrosyan Taron , Vlček Daniel
Published: December 2020

Aim of this work was to study flow boiling in an annular channel at low pressure and low flow on a tube with modified surface roughness. The tube with the outer diameter of 9.14 mm and the heated length of 380 mm was made of Inconel 625 and was manually modified using 150 grit sandpaper. The tube was placed in a glass tube with an inner diameter of 14.8 mm. Outlet pressure was set to 120, 200 and 300 kPa with varying mass flow from 400 to 600 kg/(m2.s). A high speed camera was used to record several experiments to fully understand ongoing phenomena. Surface roughness was analysed using a confocal laser microscope and the effects of different mass flux and pressure on the CHF value were observed. Above all, the optimization of the flow parameters was done from the collected data and from the observed behaviour of the experimental loop.
METHODS OF XS DATA PREPARATION FOR GEOMETRY WITH FUEL DUMMY
Authors: Suk Pavel
Published: December 2020

3D deterministic core calculation represents important category of the nuclear fuel cycle and safe Nuclear Power Plant operation. The appropriate solution was not published yet. Data preparation process for non-fuel elements of the core represents the challenge for scientists. This report briefly introduce the problem of the data preparation process and gives the information about new input format for macrocode PARCS (PMAXS). The best homogenization process approach is to prepare data in infinite lattice cell for fuel assemblies, which are placed next to the another fuel assembly. Data for fuel assembly located next to the non-fuel region are better with preparation in the real geometry with the real boundary conditions. Results of the neutron spectra study show that the PMAXS file format is well prepared for the 2 group calculation, but it is not well prepared for the multigroup calculations, however the XSEC file format still gave reasonable results.
EXPERIMENTAL INVESTIGATION OF CRITICAL HEAT FLUX IN ANNULUS AT LOW PRESSURE AND LOW FLOW PARAMETERS
Authors: Vlček Daniel , Suk Ladislav , Števanka Kamil , Petrosyan Taron
Published: December 2020

Steady state flow boiling experiments were conducted on a technically smooth Inconel 625 tube with outer diameter 9.1 mm at inlet pressures 131, 220 and 323 kPa, inlet temperatures 62, 78 and 94 °C and approximately 400, 600 and 1000 kg/(m2.s) mass flow. Water of these parameters was entering into the vertically aligned annulus, where the uniformly heated tube was placed until the critical heat flux (CHF) appeared. The experimental data were compared to estimations of CHF by local PGT tube correlation and Groeneveld’s look-up tables for tubes. The results imply that in the region of low pressure and low mass flux, the differences between calculations and experiments are substantial (more than 50 % of CHF). The calculations further imply that look-up tables and tube correlations should be corrected to the annulus geometry. Here, the Doerffer’s approach was chosen and led to a substantial enhancement of CHF estimation. Yet, a new correlation for the region of low pressure and flow is needed.

Published: December 2020

Este artigo traz resultados de uma pesquisa cujo objetivo foi investigar a coerência de conteúdos e formas na Geometria, presentes em três coleções de livros didáticos do 2º ano dos Anos Iniciais e na Provinha Brasil norteada pelos Parâmetros Curriculares Nacionais (PCN) e pelos Elementos Conceituais e Metodológicos (ECM) para a Definição dos Direitos de Aprendizagem e Desenvolvimento do Ciclo de Alfabetização (1º, 2º e 3º anos) do Ensino Fundamental. A pesquisa teve abordagem qualitativa e documental. Os três livros didáticos foram recomendados pelo Programa Nacional do Livro Didático (PNLD) e utilizados em escolas da rede pública e privada de ensino no município de Santa Maria/RS. Foram analisadas as questões que faziam referência ao conteúdo de Geometria das Provinhas Brasil aplicadas nos anos de 2011 a 2015. A análise dos livros didáticos foi categorizada quanto à estrutura e formatação, conteúdo, linguagem e ilustrações. Este estudo possibilitou estabelecer categorias, de acordo com o conteúdo contemplado e as habilidades que devem ser desenvolvidas. Concluiu-se que a Geometria está cada vez mais presente e atual, tanto nos Livros didáticos (LD) dos Anos iniciais (AI), quanto na Provinha Brasil e nos ECM. Isso indica uma tendência de fornecer aos professores desse seguimento subsídios para que possam trabalhar com a Geometria e atingir o desenvolvimento matemático geométrico que o aluno necessita nesse ano escolar.
A infraestrutura escolar no cerne das aulas de Educação Física: O sucateamento de sistemas públicos de ensino
Authors: Ferreira Neto Rubem Barboza
Published: December 2020

Este artigo busca estudar relatos (ou percepções) de alunos e profissionais da educação sobre as infraestruturas escolares desportivas no processo didático-metodológico das aulas de Educação Física, em cinco escolas públicas municipais dos anos finais do ensino fundamental da cidade de Armação dos Búzios-RJ, Brasil. Para nortear o caminho epistemológico foram utilizados como pressuposto filosófico, o materialismo histórico-dialético e a concepção crítico-superadora da Educação Física brasileira. Trata-se de um estudo de método qualitativo no formato de estudo de casos múltiplos. Como técnica de recolha dos dados foram utilizadas entrevistas semiestruturadas aos participantes adultos e questionários aos alunos. Para o tratamento dos dados utilizou-se a análise de conteúdo, o que nos fez chegar a três categorias de análise: a Aprendizagem, o Espaço Físico e a Prática Pedagógica e, os Materiais. Os resultados sugerem que a prática pedagógica e as competências dos alunos são gravemente afetadas nas aulas de Educação Física pela ineficiência pública de provisão de materiais e pelo tipo e qualidade dos espaços utilizados: ambientes não-escolares, como quadras externas e praças públicas.

Background: Obstructive Sleep Apnea Syndrome (OSAS) is sleeping-disorder that’s characterized by recurrent episodes of upper airway obstruction during sleep. Fourteen percent of world populations suffer from OSAS. OSA patients are 7.5 to 20 times more likely to have difficulties with concentration, learning new tasks, and execution of monotonous tasks.Objective: The primary objective of this study was to investigate the relationship between Obstructive Sleep Apnea Syndrome (OSAS) and concentration level in young adultsMethods: This is an analytic observational study with cross-sectional design. Sampling was carried out with total sampling. Samples that qualified the inclusion and exclusion criteria were assessed by OSAS using the Epworth Sleepiness Scale (ESS) questionnaire and Digit Symbol Substitution Test was used to assess the concentration level. The data were analyzed, using the chi-square test and the prevalence (PR) testResults: The Chi-square test showed that there was a significant relationship between OSAS and concentration level (p=0.033). The Prevalence Ratio test found that OSAS decreased concentration level by 1.55 compared to not OSASConclusion: There was a significant relationship between OSAS and concentration level in young adults. OSAS patients are 1.55 more likely to have a decrease concentration level when compared with healthy individuals
Intact Behavioral Expression of Contextual Fear, Context Discrimination, and Object Discrimination Memories Acquired in the Absence of the Hippocampus
Authors: Gidyk Darryl C. , McDonald Robert J. , Sutherland Robert J.
Published: December 2020

We test the hypothesis that the stability and precision of context and visual discrimination memories depend on interactions between the hippocampus (HPC) and other memory storage networks. In four experiments we tested the properties of memories acquired in the absence of the HPC. Long–Evans male rats were exclusively used in all experiments. Experiment 1 evaluated acquisition and retention of context fear memories in rats with prior partial or complete HPC damage. Confirming an earlier report (Zelikowsky et al., 2012) a very small but statistically reliable slowing in a single session of context fear conditioning was found after HPC damage. In contrast, retention of context fear memory was normal after HPC damage up to 30 d after learning. In experiment 2, we found that discrimination between a context paired with foot shocks and a different context never paired with foot shock was retained normally for 15 d. In experiment 3, we replicated the finding of intact context discrimination for at least 15 d in rats who display a significant impairment in acquisition of place learning in the Morris water task (MWT). In final experiment using an appetitive object discrimination task, we showed normal retention of the discrimination for at least 30 d after training in rats with complete HPC damage. These finding score against the idea that non HPC memory storage requires a period of interaction with HPC to establish a stable, precise memory.

SIGNIFICANCE STATEMENTContrary to expectations from systems memory consolidation, we find that in the absence of a functional hippocampus (HPC) context and visual memories are formed rapidly and exhibit normal persistence and precision. The findings suggest that the HPC is not obligatory for these features of long-term memories.

For years, adult psychological research has benefitted from web-based data collection. There is growing interest in harnessing this approach to facilitate data collection from children and adolescents to address foundational questions about cognitive development. To date, however, few studies have directly tested whether findings from in-lab developmental psychology tasks can be replicated online, particularly in the domain of value-based learning and decision-making. To address this question, we set up a pipeline for online data collection with children, adolescents, and adults, and conducted a replication of Decker et al. (2016). The original in-lab study employed a sequential decision-making paradigm to examine shifts in value-learning strategies from childhood to adulthood. Here, we used the same paradigm in a sample of 151 children (N = 50; ages 8 - 12 years), adolescents (N = 50; ages 13 - 17 years), and adults (N = 51; ages 18 - 25 years) and replicated the main finding that the use of a “model-based” learning strategy increases with age. In addition, we adapted a new index of abstract reasoning (MaRs-IB; Chierchia et al. 2019) for use online, and replicated a key result from Potter et al. (2017), which found that abstract reasoning ability mediated the relation between age and model-based learning. Our re-analyses of two previous in-lab datasets alongside our analysis of our online dataset revealed few qualitative differences across task administrations. These findings suggest that with appropriate precautions, researchers can effectively examine developmental differences in learning computations through unmoderated, online experiments.
How I May Destroy You Reinvents Rape Television
Authors: Benson-Allott Caetlin
Published: December 2020

British and American television shows frequently deploy rape and sexual assault to juice up characters’ backstories or titillate viewers, but they rarely focus on how one assault impacts multiple people’s lives or how intersectional oppression further traumatizes assault survivors. FQ columnist Caetlin Benson-Allott suggests that this may change in the wake of Michaela Coel’s incendiary series I May Destroy You (BBC One and HBO, 2020), which has answered a need for more artistically ambitious television about black life and for feminist-of-color critiques of rape culture on television. Hailing the series for its formal innovations as well as its generic and political interventions, Benson-Allott argues that I May Destroy You elevates its genre, and television more broadly, by contesting their prior shortcomings.
The Monstrification of Underdevelopment in Contemporary Brazilian Cinema
Authors: Andrade Fábio
Published: December 2020

This article articulates how two recent Brazilian medium-length films challenge the category of the “hybrid film,” incorporating reenactment to recompose invisible routines of institutionalized oppression. In Seven Years in May, Affonso Uchôa (Araby; The Hidden Tiger) uses collaborative methods to render visible the structure of mass incarceration in Minas Gerais. Shot with a group of young men in Contagem, the film is a tryptic where each part employs a different mode of narrative reconstruction. Directed by a group of first-time Guarani-Kaiowá filmmakers, Ava Yvy Vera retells the murder of their leader, Nisio Gomes, by forty masked gunmen in 2011. The film uses reenactment to infiltrate the present with the past, reviving Gomes through the palpability of his absence. In both cases, aesthetic choices disturb the legibility of events, questioning the authoritative inclination of narrative clarity in both fiction and documentary, as well as the glacial category of the hybrid film.
Melodrama, Telenovela, and the New Latin American Women’s Picture
Authors: Betancourt Manuel
Published: December 2020

FQ columnist Manuel Betancourt examines how the Latin American tradition of melodrama is being reimagined by contemporary filmmakers in ways that reveal its ongoing relevance. Focusing on four recent films—Los adioses (The Eternal Feminine, dir. Natalia Beristáin, 2017), Amores modernos (Modern Loves, dir. Matías Meyer, 2020), La quietud (The Quietude, dir. Pablo Trapero, 2018), and A vida invisível (Invisible Life, dir. Karim Aïnouz, 2019)—Betancourt suggests that these recent riffs on the genre present fertile ground for narratives about how women’s agency and bodies remain tethered to patriarchal systems. Indeed, melodrama’s status as a gendered genre and association with women and their stories is central to its recuperation and reformulation in the twenty-first century as a means to reckon with national discourses about the family that may feel personal but are inherently political.

Published: December 2020

The core intention of the researchers is to develop and confirm a multi-item measurement scale for consumption related cognition through teenagers’ involvement in Television Commercial (TVC) of developing country like Bangladesh. Another important purpose of this research is to understand the influence of TV advertisements on consumption related cognition of developing countries’ teenagers. Very limited research has been conducted on consumption related cognition through involvement of TVC, even though it is the fundamental step which activates any consumers’ — especially teenagers’ — buying stimuli. Among the limited ones conducted, most of the research work has focused on scale items, such as product knowledge, consumer perception, purchasing intention, brand perception and product usage without providing any importance to complex variable or factors of consumption related cognition from which the scale items derive. Hence, an elaborated multi step research method has been used to find out and refine both the complex and simple variables of consumption related cognition through TVC involvement. Research findings have been statistically verified using exploratory and confirmatory factor analysis techniques. This research has revealed six main complex variables or factors namely consumption related- cognitive awareness, cognitive knowledge, cognitive mapping, cognitive linkage, cognitive complexity and cognitive skills. Four to five multi item measurement scales have been derived from each of the six factors.
