O PAPEL DA EXTENSÃO NA FORMAÇÃO DO PROFESSOR: UMA ANÁLISE DO PROJETO EDUJORNALISMO DA UNIVERSIDADE REGIONAL DE BLUMENAU
Authors: Moraes Juliana De Mello , Zendron da Cunha Karina , Galarça Sandro Lauri da Silva
Published: April 2023

Atualmente, a onipresença das tecnologias digitais exige novas práticas tanto entre estudantes quanto entre professores. Nesse contexto, a formação dos professores não deve ignorar os novos processos sociais relacionados às tecnologias, devendo incorporar propostas formativas sobre o tema. Essa pesquisa é resultado das reflexões realizadas no âmbito do projeto de extensão "Edujornalismo para o Letramento Digital", da Universidade Regional de Blumenau. Esse projeto promove maior conscientização dos sujeitos da educação, tanto em relação à recepção quanto à produção de produtos jornalísticos e se desenvolve com a participação dos cursos de Jornalismo, História, Letras e Ciências da Computação e da comunidade escolar. Assim, o objetivo deste artigo é avaliar como esse projeto tem contribuído para a formação de futuros docentes da Educação Básica. Constatou-se que colaborou para que os envolvidos desenvolvessem novas aprendizagens, inclusive com impacto na sua atuação futura. Além disso, as atividades do projeto promoveram a aproximação entre docentes e estudantes de graduação ao ambiente escolar, questão fundamental para a formação dos futuros professores.

Published: April 2023

Este artigo busca analisar alguns resultados do projeto Objetos de Pensar, desenvolvido pelo Grupo de Pesquisa Currículo, Espaço, Movimento, no ano de 2019. Tal projeto, lançado por meio de edital, consistiu da criação de perguntas que provocassem o movimento do pensamento, bem como da construção de objetos que potencializassem reflexões sobre a docência. As propostas inscritas serviram de material para a realização de oficinas com professores e estudantes, e constituíram a exposição Objetos de Pensar, realizada no SESC/Lajeado/RS. Neste artigo, por meio de autores como Larrosa (2018) e Masschelein e Simons (2018), analisam-se duas das problematizações emergidas nas oficinas: a) o despertar da vontade no estudante; b) os estudantes não são autônomos. Conclui-se que as questões destacadas pelos professores estão imbricadas, pois, à medida que o estudante descobre o que lhe interessa, também se vê estimulado a encontrar-se e a agir no mundo de forma autônoma.

Published: April 2023

Este trabalho foi idealizado em uma disciplina, em nível de Doutorado, no programa de Pós-Graduação em Educação na Universidade Estadual de Maringá. Teve como objetivo geral verificar a compreensão do público participante sobre os conceitos relacionados às relações étnico-raciais, dando enfoque ao racismo. A metodologia utilizada foi a aplicação um formulário online com perguntas relacionados às questões étnico-raciais, no momento de pandemia. O público-alvo foi composto por 50 profissionais da educação divididos em dois grupos, sendo um com 25 alunos/as de Pós-Graduação Stricto Sensu e 25 de docentes da rede municipal de educação, da região noroeste do Paraná, para verificar possíveis diferenças nas percepções de cada grupo. Constatamos indícios de que as formações acadêmicas em programas stricto sensu (Mestrado e Doutorado) oferecem possibilidades para que profissionais da educação tenham acesso ao conhecimento aprofundado acerca de temáticas como o racismo, em comparação a profissionais sem tal formação.

Published: April 2023

O presente artigo busca discutir a curricularização da extensão a partir de um projeto de extensão denominado A linguagem da não-violência: uma possibilidade para a construção da cultura da paz – EDUPAZ. O projeto é um de vários implementados por uma universidade comunitária –XXXXX. O Plano Nacional de Educação (2014-2024) indica a necessidade de curricularizar a extensão nos cursos de graduação, o que é regulamentado pela Resolução nº 7 MEC/CNE/CES, de 18 de dezembro de 2018. A curricularização da extensão deve ser feita até dezembro de 2021, o que tem mobilizado as instituições para a elaboração de diretrizes para cumprir com a legislação. Os dados que fundamentaram esta discussão, foram obtidos de relatórios e trabalhos desenvolvidos pelos extensionistas do EDUPAZ de 2016 a 2020. Os resultados indicam que as atividades desenvolvidas foram relevantes tanto para os acadêmicos como para a comunidade que participou, o que aponta a necessidade de incorporar as iniciativas de projetos e programas já existentes nas instituições no modelo de curricularização da extensão.

Dentro da perspectiva de uma revisão bibliográfica buscou-se nesse artigo analisar as produções relacionadas ao Tradutor Intérprete de Libras/Língua Portuguesa no Estado de Goiás. Trata-se de um mapeamento e análise do que foi produzido com base no método Prisma (GALVÃO; PANSANI; HARRAD, 2015) nos últimos dez anos (2010-2019), a partir de teses e dissertações disponíveis no banco de dados da CAPES. A amostra final foi composta por seis dissertações, cuja seleção se deu após a leitura dos títulos, resumos e textos completos. Foram categorizadas quanto às principais temáticas abordadas, relacionadas à formação dos tradutores intérpretes de Libras/Língua Portuguesa, sua atuação e relação com os professores regentes de salas de aulas regulares. Na maioria dos estudos identificou-se que a formação dos intérpretes é deficitária e sua atuação não atende a legislação nacional e estadual vigentes, bem como às diretrizes relacionadas ao perfil, requisitos e atribuições destes profissionais, além de dificuldades na relação deles com os professores. Isso implica, de acordo com os estudos, a um atendimento inadequado aos alunos surdos e sua inclusão no processo de ensino-aprendizagem na educação básica de Goiás.

O INFAMILIAR E A NOÇÃO DE ESTRANHAMENTO EM NO PÂNTANO DOS GATOS…, DE MARINA CARR
Authors: Monteiro de Vasconcelos Leonardo
Published: April 2023

Este artigo tem como principal objetivo analisar o infamiliar (das unheimliche), proposto por Sigmund Freud (1919/2019), e a noção de estranhamento (unhomeliness), desenvolvida por Homi K. Bhabha (1992, 1998), na peça No Pântano dos Gatos... , escrita pela dramaturga irlandesa Marina Carr (2017). Proponho defender que a protagonista Hester Swane se depara com o sentimento de infamiliar/estranhamento quando se recusa a aceitar o exílio imposto. Para tanto, apresento a importância do pântano na literatura irlandesa e a conexão afetiva que a personagem Hester Swane tem com o Pântano dos Gatos. Também discuto a noção de infamiliar e de estranhamento proposto por Freud e Bhabha, respectivamente. Como aporte crítico, baseio meus escritos, principalmente, em Gladwin (2014), Freud (1919/2019) e Bhabha (1992, 1998).
A História da literatura brasileira, de Silvio Romero: breves olhares sobre o método etnográfico
Authors: Da Silva Ariane De Andrade
Published: April 2023

Este artigo volta-se à História da literatura brasileira (1888), na tentativa de discutir o método etnográfico empregado por Silvio Romero. Na viragem do século XIX para o século XX, a História da literatura de Romero apresenta uma abordagem de fatos literários e culturais, numa leitura de seu tempo e dos progressos que levariam ao adensamento e à formação da literatura brasileira. Objetiva-se o desenvolvimento de uma reflexão sobre o lugar da nacionalidade brasileira na referida historiografia, bem como sobre a importância dada ao desenvolvimento de uma autonomia literária brasileira. Ainda, cabe apontar o Romantismo como momento representativo de transição à independência literária, posto que as bases românticas consubstanciaram-se na originalidade e no abandono à imitação. Como aporte teórico, destacam-se, entre outros, Abdala Junior (2008), Alfredo Bosi (2002) e Clifford Geertz (1978).
As irmãs – ou seriam amigas? – de Shakespeare: descobrindo e lendo mulheres escritoras da modernidade nascente inglesa
Authors: Thosi Aline Fernandes
Published: April 2023

Em um de seus ensaios feministas entitulado Um teto todo seu (1929), Virginia Woolf (1882-1941) questiona a aparente ausência de mulheres escritoras no Renascimento inglês. A indagação de Woolf é pertinente, uma vez que a literatura masculina era, irrefutavelmente, dominante na modernidade nascente.  O presente artigo propõe um retorno à era do Bardo – de mãos dadas com Woolf – para que seja feita uma investigação sobre as possíveis autoras inglesas contemporâneas de Shakespeare. A partir dessa investigação, um breve panorama do contexto histórico e do cenário literário feminino na Inglaterra dos séculos XVI e XVII será apresentado.
Meniscus cell lysate induces mitochondrial dysfunction of fibroblast-like synoviocytes via upregulating ANT3 in osteoarthritis
Authors: Du Xue , Jiang Zongrui , Fang Guibin , Liu Ruonan , Wen Xingzhao , Wu Yinjuan , Hu Shu , Zhang Zhiqi
Published: April 2023

Aims

This study aimed to investigate the role and mechanism of meniscal cell lysate (MCL) in fibroblast-like synoviocytes (FLSs) and osteoarthritis (OA).

Methods

Meniscus and synovial tissue were collected from 14 patients with and without OA. MCL and FLS proteins were extracted and analyzed by liquid chromatography‒mass spectrometry (LC‒MS). The roles of MCL and adenine nucleotide translocase 3 (ANT3) in FLSs were examined by enzyme-linked immunosorbent assay (ELISA), flow cytometry, immunofluorescence, and transmission electron microscopy. Histological analysis was performed to determine ANT3 expression levels in a male mouse model.

Results

We discovered for the first time that MCL was substantially enriched in the synovial fluid of OA patients and promoted the release of inflammatory cytokines from FLSs through MCL phagocytosis. Through LC‒MS, ANT3 was identified and determined to be significantly upregulated in MCL and OA-FLSs, corresponding to impaired mitochondrial function and cell viability in OA-FLSs. Mitochondrial homeostasis was restored by ANT3 suppression, thereby alleviating synovial inflammation. Furthermore, elevated ANT3 levels inhibited ERK phosphorylation. Specifically, silencing ANT3 prevented inhibition of ERK phosphorylation and significantly reduced the elevation of reactive oxygen species (ROS) and JC1 membrane potential in MCL-induced synovial inflammation.

Conclusion

This study revealed the important roles of MCL and ANT3 in FLS mitochondria. Silencing ANT3 rescued ERK phosphorylation, thereby restoring mitochondrial homeostasis in FLSs and alleviating synovitis and OA development, offering a potential target for treating synovitis and preventing early-stage OA.

Building bridges in place of barriers between school practitioners and researchers: on the role of embedded intermediaries in promoting evidence-based policy
Authors: Brants Hagit Sabo , Ariel Barak
Published: April 2023

Background:

The literature on evidence-based policy in education offers insight into the need to form partnerships between researchers and practitioners with particular attention to the role of intermediaries. However, the operationalisation of the partnership, especially in school violence prevention, the focal policy of this research, remains unclear.

Objectives:

To identify potential intermediaries and explore their role in forming an evidence-based school violence prevention policy.

Method:

In-depth interviews with headteachers and members of school executive teams in Israel.

Findings:

The participants discussed three types of possible intermediaries that could facilitate a relationship between researchers and practitioners – internal inspectors, school counsellors, and external academics.

Discussion and conclusions:

We concluded that embedded intermediaries are needed to form a bridge between practice and research in the area of school violence prevention. These embedded intermediaries ought to have expertise in research methods, as well as expertise in an educational subject matter, and must be committed to the scientific approach rather than to political or organisational agendas. The formation of the research partnership must be inclusive and marked by the involvement of middle-rank policymakers (for example, headteachers) in the selection of the research questions and methodology and in the implementation of policy implications. Otherwise, evidence-based policy is unlikely to take root.

Published: April 2023

The transmission of constant envelope orthogonal frequency division multiplexing (CE-OFDM) signals is experimentally demonstrated in this paper to increase the reach of metro-regional optical links. A recirculating fiber loop was implemented for this aim. A reach extension of 100 km of standard single-mode fiber was achieved with the CE-OFDM-based system, considering 16 quadrature amplitude modulation (16-QAM) as subcarrier mapping and links without optical dispersion compensation. Link lengths as long as 700 km, with spectral efficiency of 1.89 b/s/Hz, were accomplished with performances below the forward error correction limit.
All-dielectric metasurface based ultranarrow bandpass filter in optical C-band

Published: April 2023

Metasurface-based nanophotonics devices can potentially replace traditional bulky optical components such as optical filters, modulators, and switches. In this study, we report a dielectric metasurface-based ultranarrow bandpass filter operating at 1549.8 nm with the ability to tune the central wavelength within the C-band. The proposed tunable filter consists of a 2D periodic array of gallium arsenide blocks placed on top of a quartz substrate. The introduction of a symmetry-breaking defect results in an ultranarrow resonance with an FWHM of 0.31 nm at a 1549.8 nm wavelength when a TE-polarized wave is normally incident. The sharp, high Q factor resonance is understood to be governed by the symmetry-protected bound state in the continuum. The resonant response can be tuned by changing the periodicity, thickness, and asymmetry of the metasurface constituents. The multipolar analysis indicates the excitation of the electric quadrupole mode at the resonance wavelength. Our findings can be useful for the design of compact tunable ultranarrow bandpass filters for optical communications systems.

Published: April 2023

The dual-polarization interferometric fiber optic gyroscope (IFOG) has been studied for many years and achieved remarkable performance. In this study, we propose a novel dual-polarization IFOG configuration based on a four-port circulator, in which the polarization coupling errors and the excess relative intensity noise are well handled meanwhile. Experimental measurements of the short-term sensitivity and long-term drift using a fiber coil with a length of 2 km and a diameter of 14 cm show that the angle random walk of 5.0×10−5∘/h and bias instability of 9.0 × 10−5 °/h are achieved. Moreover, the root power spectrum density of 20nrad/s/Hz is almost flat from 0.001 Hz to 30 Hz. We believe this dual-polarization IFOG is a preferred candidate for the reference-grade performance IFOG.
Simultaneous measurements of Ka-band microwave angle of arrival and Doppler frequency shift based on a silicon DPMZM
Authors: Zhang Qiang , Chen Sihan , Li Yan , Yu Hui
Published: April 2023

We propose a system for the simultaneous measurements of Ka-band microwave angle of arrival (AOA) and Doppler frequency shift (DFS) based on a high-speed silicon dual-parallel Mach-Zehnder modulator (Si-DPMZM).. An echo signal drives a sub-MZM while the combination of a phase-delay echo signal and a transmitted signal drives the other sub-MZM. Two optical bandpass filters (OBPFs) are used to select the upper and lower sidebands of the Si-DPMZM output signal, detected by low-speed photodiodes, then generating two intermediate frequency (IF) signals. Thus, both AOA and DFS (with direction) can be obtained by comparing the powers, phases and frequencies of these IF signals. The estimation error of measured AOA is less than ±3° from 0 to ±90°. Meanwhile, the DFS at 30/40 GHz were measured with an estimated error of less than 9.8 × 10−10 Hz within ±1 MHz. In addition, the fluctuation of DFS measurement is less than 3 × 10−11 Hz within 120 minutes, indicating the high stability of the system.

Published: April 2023

Fiber-optic devices working in the visible and near-infrared windows are attracting attention due to the rapid development of biomedicine that involves optics. In this work, we have successfully realized the fabrication of near-infrared microfiber Bragg grating (NIR-µFBG), which was operated at the wavelength of 785 nm, by harnessing the fourth harmonic order of Bragg resonance. The NIR-µFBG provided the maximum sensitivity of axial tension and bending to 211 nm/N and 0.18 nm/deg, respectively. By conferring the considerably lower cross-sensitivity, such as response to temperature or ambient refractive index, the NIR-µFBG can be potentially implemented as the highly sensitive tensile force and curve sensor.
Sunglint reflection facilitates performance of spaceborne UV sensor in oil spill detection

Published: April 2023

Ultraviolet Imager (UVI) onboard Haiyang-1C/D (HY-1C/D) satellites has been providing ultraviolet (UV) data to detect marine oil spills since 2018. Although the scale effect of UV remote sensing has been preliminarily interpreted, the application characteristics of spaceborne UV sensors with medium spatial resolution in oil spill detection deserve further investigation, especially the role of sunglint in the process of detection. In this study, the performance of the UVI is thoroughly assessed by the following aspects: image features of oils under sunglint, sunglint requirement for spaceborne UV detection of oils, and the stability of the UVI signal. The results indicate that in UVI images, it is sunglint reflection that determines the image features of spilled oils, and the appearance of sunglint can strengthen the contrast between oils and seawater. Besides, the required sunglint strength in spaceborne UV detection has been deduced to be 10−3 - 10−4 sr-1, which is higher than that in the VNIR wavelengths. Moreover, uncertainties in the UVI signal can meet the demand to discriminate between oils and seawater. The above results can confirm the capability of the UVI and the critical role of sunglint in spaceborne UV detection of marine oil spills, and provide new reference for spaceborne UV remote sensing.

Published: April 2023

Objectives

Face masks are low-cost, but effective in preventing transmission of COVID-19. To visualize public’s practice of protection during the outbreak, we reported the rate of face mask wearing using artificial intelligence-assisted face mask detector, AiMASK.

Methods

After validation, AiMASK collected data from 32 districts in Bangkok. We analyzed the association between factors affecting the unprotected group (incorrect or non-mask wearing) using univariate logistic regression analysis.

Results

AiMASK was validated before data collection with accuracy of 97.83% and 91% during internal and external validation, respectively. AiMASK detected a total of 1,124,524 people. The unprotected group consisted of 2.06% of incorrect mask-wearing group and 1.96% of non-mask wearing group. Moderate negative correlation was found between the number of COVID-19 patients and the proportion of unprotected people (r = -0.507, p<0.001). People were 1.15 times more likely to be unprotected during the holidays and in the evening, than on working days and in the morning (OR = 1.15, 95% CI 1.13–1.17, p<0.001).

Conclusions

AiMASK was as effective as human graders in detecting face mask wearing. The prevailing number of COVID-19 infections affected people’s mask-wearing behavior. Higher tendencies towards no protection were found in the evenings, during holidays, and in city centers.
The limiting zero dynamics of discrete-time system based on forward triangle sample-and-hold
Authors: Ou Minghui , Ou Mingkun , Wang Haiyang
Published: April 2023

Zero dynamics have crucial effect on system analysis and controller design. In the control analysis process, system performance is influenced by the unstable zero dynamics, greatly. This study concerns with the properties of limiting zero dynamics when the signal of controlled continuous-time systems was reconstructed by forward triangle sample-and-hold (FTSH). FTSH is a newly sample and hold method in the signal reconstruction area. However, more theoretical details about the limiting zero dynamics of the resulting discrete-time systems need to be revealed. Firstly, the framework for the limiting zero dynamics in the situation of sufficiently small or large sample period is introduced. Furthermore, this study provides the stable conditions of limiting zeros in the two different sampling situations. The results indicate that one can select a suitable variable parameter value of FTSH to replace the sampling zeros of discrete-time system locate inside the stable region. This paper also reveals the truth that FTSH has the outstanding advantage compared with the BTSH using theoretical analysis method. Finally, example simulations verify the effectiveness of the results in this study.
Antecedents of the red-romance effect: Men’s attractiveness and women’s fertility
Authors: Agthe Maria , Niesta Kayser Daniela , Schwarz Sascha , Maner Jon K.
Published: April 2023

The color red has been implicated in a variety of social processes, including those involving mating. While previous research suggests that women sometimes wear red strategically to increase their attractiveness, the replicability of this literature has been questioned. The current research is a reasonably powered conceptual replication designed to strengthen this literature by testing whether women are more inclined to display the color red 1) during fertile (as compared with less fertile) days of the menstrual cycle, and 2) when expecting to interact with an attractive man (as compared with a less attractive man and with a control condition). Analyses controlled for a number of theoretically relevant covariates (relationship status, age, the current weather). Only the latter hypothesis received mixed support (mainly among women on hormonal birth control), whereas results concerning the former hypothesis did not reach significance. Women (N = 281) displayed more red when expecting to interact with an attractive man; findings did not support the prediction that women would increase their display of red on fertile days of the cycle. Findings thus suggested only mixed replicability for the link between the color red and psychological processes involving romantic attraction. They also illustrate the importance of further investigating the boundary conditions of color effects on everyday social processes.
Effect of frequency and rhythmicity on flicker light-induced hallucinatory phenomena
Authors: Amaya Ioanna Alicia , Behrens Nele , Schwartzman David John , Hewitt Trevor , Schmidt Timo Torsten
Published: April 2023

Flicker light stimulation (FLS) uses stroboscopic light on closed eyes to induce transient visual hallucinatory phenomena, such as the perception of geometric patterns, motion, and colours. It remains an open question where the neural correlates of these hallucinatory experiences emerge along the visual pathway. To allow future testing of suggested underlying mechanisms (e.g., changes in functional connectivity, neural entrainment), we sought to systematically characterise the effects of frequency (3 Hz, 8 Hz, 10 Hz and 18 Hz) and rhythmicity (rhythmic and arrhythmic conditions) on flicker-induced subjective experiences. Using a novel questionnaire, we found that flicker frequency and rhythmicity significantly influenced the degree to which participants experienced simple visual hallucinations, particularly the perception of Klüver forms and dynamics (e.g., motion). Participants reported their experience of geometric patterns and dynamics was at highest intensity during 10 Hz rhythmic stimulation. Further, we found that frequency-matched arrhythmic FLS strongly reduced these subjective effects compared to equivalent rhythmic stimulation. Together, these results provide evidence that flicker rhythmicity critically contributes to the effects of FLS beyond the effects of frequency alone, indicating that neural entrainment may drive the induced phenomenal experience.
Association between watching wide show as a reliable COVID-19 information source and preventive behaviors: A nationwide survey in Japan
Authors: Kuwahara Keisuke , Kato Mio , Ishikawa Hirono , Shinozaki Tomohiro , Tabuchi Takahiro
Published: April 2023

Introduction

Current pandemic prompted a surge in the television (TV) news watching. However, its influence is poorly understood. In Japan, wide show, a major genre of soft news TV programs, broadcasted COVID-19 for long hours, and was pointed out that it broadcasted COVID-19 sensationally, arousing fear and anxiety, and that it criticized individuals gathering in closed places. Thus, wide show may promote preventive behaviors but also produce fear or anxiety and aggressiveness towards others not engaging in preventive behaviors. We examined this issue using large-scale nationwide data.

Methods

We analyzed the cross-sectional data of 25,482 individuals from the Japan COVID-19 and Society Internet Survey conducted in 2020. Participants reported the type of COVID-19 information sources including TV news and wide show, and their trustworthiness. We calculated multivariable-adjusted prevalence ratios (PRs) of engaging in recommended preventive behaviors strictly (defined as always engaging in hand washing, mask wearing, and attempting to keep physical distancing) and alerting others not engaging in preventive behaviors, respectively.

Results

About 72.4% of the participants obtained information from TV news with reliance, while corresponding values were 50.3% for wide show. Overall, 32.8% engaged in recommended preventive behaviors strictly, and 9.6% alerted others. Watching wide show both with and without reliance were significantly associated with alerting others (adjusted PRs: 1.48 and 1.34, respectively) but not associated with preventive behaviors. Watching TV news was neither associated with strict preventive behaviors nor alerting others.

Conclusion

Watching TV news and wide show was not associated with strict preventive behaviors; watching wide show was associated with only alerting others. Although causality is unclear, actions may be needed for TV stations broadcasting wide show to understand own influences on society in a timely manner amid the health emergencies.
Mobiltechnológiával támogatott kutatásalapú tanulás

Published: April 2023

Learning supported by mobile technology is extremely popular today because these technologies can support learning in different contexts. Mobile phones, e-book readers, MP3 and portable media players, tablets, laptops, smartphones, and GPS receivers can be considered mobile technology. As it can be seen from this list, they are different IT devices that can be held in the hand. Since they are portable devices, they enable learning regardless of time and place. The learning and teaching processes realized with mobile technology are called mobile learning (m-learning). Not only the device but also the student and learning are mobile. In the 2000s, research was published in the international literature in which mobile technologies supported learning by supplementing inquiry-based learning (IBL). Mobile technology-supported inquiry-based learning (mIBL) offers potential opportunities to support different levels of inquiry and generate new types of research; it helps to arouse and maintain students’ curiosity and motivation; it connects formal school and informal natural science learning related to everyday life. Although the research results so far show that mobile technology provides adequate support for IBL learning processes, practical strategies, recommendations, and guidelines are needed for further development and appropriate educational application. This study reviews the characteristics and practical applications of mobile learning through mobile technologies, emphasizing the support of inquiry-based learning.
TEMPERATURA SUPERFICIAL TERRESTRE E NDVI DOS BAIRROS DA ÁREA URBANA DE ARAPIRACA – AL: UMA ANÁLISE A PARTIR DAS ESTATÍSTICAS ZONAIS
Authors: Silva Joao Pedro Luiz Santos da , Ribeiro Daniela Dantas de Menezes
Published: April 2023

O presente artigo tem como objetivo realizar uma análise comparativa entre a cobertura vegetal, dada pelo Normalized Difference Vegetation Index (NDVI), e a Temperatura Superficial Terrestre (TST) da área urbana do município de Arapiraca, Alagoas, utilizando para isso as estatísticas zonais extraídas dos bairros. Para a execução do trabalho foram utilizadas as bandas 2,3,4,5 e 8 do satélite Landsat8 para composição de imagens do terreno e mapeamento do NDVI, e a banda 10 para o mapeamento da TST da área de estudo. Com base nas estatísticas zonais observa-se uma correlação negativa entre os valores de NDVI e TST, ou seja, os bairros que apresentam valores altos de NDVI, em geral, mostram valores baixos de TST, e aqueles que apresentam valores baixos de NDVI, indicam altos valores de TST, o que sugere maiores concentrações de áreas com vegetação em bairros com menores valores de TST. Nesse contexto, as técnicas de processamento de imagens aplicadas aos dados de satélite podem ser utilizadas nas ações de monitoramento e planejamento ambiental urbano, detectando alterações na vegetação e mudanças na temperatura da superfície do terreno relacionadas às atividades antrópicas.
ANÁLISE TEMPORAL DE CHUVA-VAZÃO EM UMA SEÇÃO AMOSTRAL DO RIO CLARO, REGIÃO NOROESTE DE MINAS GERAIS
Authors: Souza Luiz Humberto de Freitas , Oliveira Luiz Antonio de , Rodrigues Silvio Carlos
Published: April 2023

O presente trabalho visa apresentar a análise temporal dos registros de vazão e chuva, para uma seção amostral do rio Claro, localizado no município de Guarda-Mor, região noroeste de Minas Gerais. O ponto de monitoramento encontra-se em uma área de conflito devido ao fato da demanda do uso de recursos hídricos superficiais ser superior ao limite outorgável. O dispositivo legal que prevê o processo de outorga coletiva e a alocação negociada, requer o conhecimento sobre o comportamento hidrológico das vazões de um curso d’água. Assim, são comumente utilizados os dados fluviométricos e pluviométricos disponibilizados pelo HidroWeb, que compõe o Sistema Nacional de Informações sobre Recursos Hídricos (SNIRH-ANA). Nesse estudo em específico, apesar da existência de uma estação pluviométrica vizinha a estação fluviométrica de referência, não foi possível utilizar seus dados imediatamente, face às falhas constatadas nos registros diários de chuva, sendo necessário recorrer aos métodos estatísticos de análise de correlação e de regressão entre as estações mais afastadas, de modo a qualificar os dados pluviométricos dessas, e possibilitar a aplicação das informações nas análises de chuva-vazão. Nesse sentido, esse trabalho almeja apresentar também, o processo de descrição e teste da significância das relações entre os referidos pares ordenados de precipitação.
A proposed typology of improvement science in state ESSA plans
Authors: Cunningham Kathleen M. W. , Osworth David
Published: April 2023

This study aims to illustrate how states include an improvement science approach to educational improvement in their Every Student Succeeds Act (ESSA) state plan. Through a qualitative content analysis of 52 state ESSA plans, we propose an introductory organizational typology to categorize states based on their explicit inclusion of improvement science-related terminology in their plan. Our typology included three categories: Non-Presence, Emergent Presence, and Presence. Our findings suggest that states varied in how much improvement science language was included in their state plans. Findings also show there is little evidence of geographic diffusion of improvement science policy. This research connects a practice to policy gap highlighting educational stakeholders including educational professionals are increasingly using improvement science to address pressing problems of practice in their contexts in service of making the educational system more equitable; however, improvement science language is rarely included through the formalized state ESSA plans.

Using the 16HBE 14o‐ human airway epithelial cell culture model, calcitriol (Vitamin D) was shown to improve barrier function by two independent metrics – increased transepithelial electrical resistance (TER) and reduced transepithelial diffusion of 14C‐D‐mannitol (Jm). Both effects were concentration dependent and active out to 168 h post‐treatment. Barrier improvement associated with changes in the abundance of specific tight junctional (TJ) proteins in detergent‐soluble fractions, most notably decreased claudin‐2. TNF‐α‐induced compromise of barrier function could be attenuated by calcitriol with a concentration dependence similar to that observed for improvement of control barrier function. TNF‐α‐induced increases in claudin‐2 were partially reversed by calcitriol. The ERK 1,2 inhibitor, U0126, itself improved 16HBE barrier function indicating MAPK pathway regulation of 16HBE barrier function. Calcitriol's action was additive to the effect of U0126 in reducing TNF‐ α ‐induced barrier compromise, suggesting that calcitriol may be acting through a non‐ERK pathway in its blunting of TNF‐ α – induced barrier compromise. This was supported by calcitriol being without effect on pERK levels elevated by the action of TNF‐α. Lack of effect of TNF‐ α on the death marker, caspase‐3, and the inability of calcitriol to decrease the elevated LC3B II level caused by TNF‐α, suggest that calcitriol's barrier improvement does not involve a cell death pathway. Calcitriol's improvement of control barrier function was not additive to barrier improvement induced by retinoic acid (Vitamin A). Calcitriol improvement and protection of airway barrier function could in part explain Vitamin D's reported clinical efficacy in COVID‐19 and other airway diseases.

Hypoxia in the neonatal period is associated with early manifestations of adverse cardiovascular health in adulthood including higher risk of hypertension and atherosclerosis. We hypothesize that this occurs due to activation of lysyl oxidases (LOXs) and the remodeling of the large conduit vessels, leading to early arterial stiffening. Newborn C57Bl/6 mice were exposed to hypoxia (FiO2 = 11.5%) from postnatal day 1 (P1) to postnatal day 11 (P11), followed by resumption of normoxia. Controls were maintained in normoxia. Using in vivo (pulse wave velocity; PWV) and ex vivo (tensile testing) arterial stiffness indexes, we determined that mice exposed to neonatal hypoxia had significantly higher arterial stiffness compared with normoxia controls by young adulthood (P60), and it increased further by P120. Echocardiography performed at P60 showed that mice exposed to hypoxia displayed a compensated dilated cardiomyopathy. Western blotting revelated that neonatal hypoxia accelerated age‐related increase in LOXL2 protein expression in the aorta and elevated LOXL2 expression in the PA at P11 with a delayed decay toward normoxic controls. In the heart and lung, gene and protein expression of LOX/LOXL2 were upregulated at P11, with a delayed decay when compared to normoxic controls. Neonatal hypoxia results in a significant increase in arterial stiffness in early adulthood due to aberrant LOX/LOXL2 expression. This suggests an acceleration in the mechanical decline of the cardiovascular system, that contributes to increased risk of hypertension in young adults exposed to neonatal hypoxia that may increase susceptibility to further insults.

Objectives

The use of Bruton’s tyrosine kinase (BTK) inhibitors has changed the clinical history of patients with chronic lymphocytic leukemia (CLL) in both naïve and relapsed/refractory settings. “Accelerated” chronic lymphocytic leukemia (a-CLL) is a relatively rare form of CLL representing less than 1 % of all CLL cases. a-CLL patients usually have a more aggressive course and a reduced overall survival was reported with conventional chemo-immunotherapy approaches.

Methods

The role of Bruton Tyrosine Kinase-inhibitor, ibrutinib, in a-CLL is well established with encouraging preliminary results.

Results

We report a case of a-CLL-treated first-line with second-generation BTKi, acalabrutinib with a prompt clinical response. As known, it is the first literature report on acalabrutinib in a-CLL highlighting the role of second-generation BTKi also in this high-risk setting.

Conclusions

Target therapies (Bruton Kinase inhibitors and Bcl2 inhibitors) have improved the therapeutic landscape of CLL. The availability of therapeutic targets requires greater diagnostic accuracy to choose the most appropriate therapy for each patient.
Digging deep: hoary marmots (Marmota caligata) use refuge burrows excavated by grizzly bears (Ursus arctos)

Hoary marmots (Marmota caligata) dig burrows in alpine meadows rich in forage as ready refuge from potential predators. Refuge burrows enable hoary marmots to engage in risk-sensitive foraging when they are away from more secure resting burrows on talus slopes. Grizzly bears (Ursus arctos) commonly excavate refuge burrows while hunting marmots, substantially changing the physical characteristics of the burrow by removing earthen material. However, it is not known if marmots continue to use excavated burrows as refuge. We opportunistically inspected 22 burrows excavated by grizzly bears for use by marmots at two sites in northwestern Canada. We found marmot feces at 10 of 22 excavated burrows, indicating that marmots continued to use these burrows after they were excavated by bears. While marmots may dig several refuge burrows in alpine meadows, and bears may substantially modify them while hunting marmots, our observations indicate that some excavated burrows retain value for foraging marmots. However, the extent of their utility is unknown. We postulate several reasons why hoary marmots may use excavated burrows and suggest avenues for further research.
Nonprofit–Government Partnership during a Crisis: Lessons from a Critical Historical Junction
Authors: Kabalo Paula , Almog-Bar Michal
Published: April 2023

In a series of studies spanning a few decades, Salamon and his colleagues examined the interdependency between government and the voluntary sector, based on mutual complementarity in view of each sector’s weaknesses and advantages. This articles tests the relevance of Salamon’s postulates for the analysis and understanding of a concrete historical junction that had global characteristics: a state-in-formation that experienced a massive war of dire consequence for the entire fabric of life. The complexity of social problems and challenges grows in crisis situations and under extreme circumstances. Hence, intersectoral partnerships are especially relevant for the treatment of social problems precisely then. In this context, a historical case study has the advantage of allowing us to draw lessons from a crisis that already took place. Accordingly, in this article we employ Salamon’s concept of intersectoral partnership to examine relations among voluntary and state actors that operated in an arena engulfed in crisis and present the advantages of intersectoral partnership in situations of extremity and uncertainty.
Determination of fines in recycled paper
Authors: Mertoglu Elmas Gulnur , Karabulut Beyza
Published: April 2023

Waste paper, the use of which is increasing day by day as a raw material, has a heterogeneous structure as it contains non-fiber material from different sources. It is desired to have a homogeneous product when recycled. Within the scope of this study, the SEM images of the raw materials determined according to EN 643 standard and the products made with the recycling of these raw materials were examined, ash content, fines content and ash on sieve were stated and the results obtained by determining filler content (removed) and fiber fines (removed) were discussed. While the samples with the highest ash content were H3 and U3, the lowest samples were H6 and U9. It was determined that the samples with the highest fines content were H2 and U1, while the lowest samples were H4 and U2. While the samples with the highest ash on sieve were H3 and U3, the samples with the least were determined as H2 and U9. The filler content was highest in H1 and U3 samples, while the lowest was in H6 and U9 samples. The samples with the most fiber fines were found as H2 and U9, and the least as H1 and U3 samples.
