Here we report the spectral-timing results of the black hole X-ray binary 4U 1630–47 during its 2021 outburst using observations from the Hard X-ray Modulation Telescope (Insight-HXMT). Type C quasi-periodic oscillations (QPOs) in ∼1.6–4.2 Hz and quasi-regular modulation (QRM) near 60 mHz are detected during the outburst. The mHz QRM has a fractional rms of ∼10%–16% in the 8–35 keV energy band with a Q factor (frequency/width) of ∼2–4. Benefiting from the broad energy band of Insight-HXMT, we study the energy dependence of the ∼60 mHz QRM in 1–100 keV for the first time. We find that the fractional rms of the mHz QRM increases with photon energy, while the time lags of the mHz QRM are soft and decrease with photon energy. Fast recurrence of the mHz QRM, in a timescale of less than 1 hr, has been observed during the outburst. During this period, the corresponding energy spectra moderately change when the source transitions from the QRM state to the non-QRM state. The QRM phenomenon also shows a dependence with the accretion rate. We suggest that the QRM could be caused by an unknown accretion instability aroused from the corona.

Published: September 2022

We have studied the nature and origin of the soft X-ray excess detected in the interesting changing-look active galactic nucleus (CLAGN) Mrk 590 using two decades of multiwavelength observations from XMM-Newton, Suzaku, Swift, and NuSTAR. In light of vanishing soft excess in this CLAGN, we test two models, “the warm Comptonization” and “the ionized disk reflection,” using extensive UV/X-ray spectral analysis. Our main findings are as follows: (1) the soft X-ray excess emission, last observed in 2004, vanished in 2011 and never reappeared in any of the later observations; (2) we detected a significant variability (∼300%) in the observed optical–UV and power-law flux between observations with the lowest state (L
bol = 4.4 × 1043 erg s−1, in 2016) and those with the highest state (L
bol = 1.2 × 1044 erg s−1, in 2018); (3) the UV and power-law fluxes follow the same temporal pattern; (4) the photon index showed a significant variation (

in 2002 and 2021, respectively) between observations; (5) no Compton hump was detected in the source spectra, but a narrow Fe Kα line is present in all observations; (6) we detected a high-energy cutoff in power-law continuum (

) with the latest NuSTAR observations; (7) the warm Comptonization model needs an additional diskbb component to describe the source UV bump; and (8) there is no correlation between the Eddington rate and the soft excess as found in other CLAGNs. We conclude that, given the spectral variability in UV/X-rays, the ionized disk reflection or the warm Comptonization models may not be adequate to describe the vanishing soft excess feature observed in Mrk 590.
Galactic Cosmic-Ray Propagation in the Inner Heliosphere: Improved Force-field Model
Authors: Li 李 Jung-Tsung 融宗 , Beacom John F. , Peter Annika H. G.
Published: September 2022

A key goal of heliophysics is to understand how cosmic rays propagate in the solar system’s complex, dynamic environment. One observable is solar modulation, i.e., how the flux and spectrum of cosmic rays change as they propagate inward. We construct an improved force-field model, taking advantage of new measurements of magnetic power spectral density by Parker Solar Probe to predict solar modulation within the Earth’s orbit. We find that modulation of cosmic rays between the Earth and Sun is modest, at least at solar minimum and in the ecliptic plane. Our results agree much better with the limited data on cosmic-ray radial gradients within Earth’s orbit than past treatments of the force-field model. Our predictions can be tested with forthcoming direct cosmic-ray measurements in the inner heliosphere by Parker Solar Probe and Solar Orbiter. They are also important for interpreting the gamma-ray emission from the Sun due to scattering of cosmic rays with solar matter and photons.

Published: September 2022

BACKGROUND: Hepatorenal syndrome (HRS) is a devastating consequence of liver cirrhosis that is clinically categorized into two subtypes. Acute malfunction of renal role, as measured by an elevation in blood creatinine, significantly underestimates the loss in renal function in cirrhotic individuals; more accurate biomarkers are desperately required in cirrhotic patients.

AIM: The present study set out to uncover new biomarkers for the early prediction of AKI in cirrhotic cases. A comprehensive panel of biomarkers was investigated to get a clear insight into the pathogenesis of HRS.

PATIENTS AND METHODS: Participants in this study were 70 individuals from the hepatogastroenterology unit of the Theodor Bilharz Research Institute (TBRI). Detailed medical data and a physical examination were recorded. Three groups of patients have been identified; Group 1: 30 cases with compensated liver cirrhosis and normal kidney functions. Group 2: 20 cases with decompensated liver cirrhosis and normal kidney functions. Group 3: 20 cases with decompensated liver cirrhosis proved hepatorenal syndrome Type 2 h. The following biomarkers were detected in serum using the sandwich-ELISA method: Human L-arginine ELISA kit, human neutrophil gelatinase related lipocalin (NGAL), human noradrenaline (NA), human asymmetrical dimethylarginine (ADMA), human symmetric dimethylarginine (SDMA), human nitric oxide (NO), and human renin.

RESULTS: There was a highly significant difference between Groups 1 and 2 in NITRIC and ADMA. Significant differences between Groups 2 and 3 in NGAL, noradrenalin, and SDMA were observed. There was a significant difference (Group 2 vs. Group 3) in renin, NITRIC, ADMA, and L-ARGININE. There was highly significant differentiation (Group 2 vs. Group 3) in NGAL, noradrenalin, and SDMA. There was highly significant variation as per odd ratio and confidence interval between (Group 3 vs. Group 2) in NGAL.

CONCLUSION: Assessment of renal biomarkers in individuals with decompensated cirrhosis gives critical information on the etiology of AKI. Further, it may aid in the diagnosis and prognosis of AKI. Renin, NITRIC, ADMA, and L-ARGININE could be used as biomarkers to indicate HRS in individuals with advanced cirrhosis.
Revision of Ardissoneaceae (Bacillariophyta, Mediophyceae) from Micronesian populations, with descriptions of two new genera, Ardissoneopsis and Grunowago, and new species in Ardissonea, Synedrosphenia and Climacosphenia

Published: September 2022

Ardissonea was resurrected from Synedra in 1986 and was included as a genus by Round, Crawford and Mann (“The Diatoms”) in its own Family and Order. They commented that there might be several genera involved since the type species of the genus possesses a double-walled structure and other taxa placed in Ardissonea have only a single-walled structure. Two other genera of “big sticks,” Toxarium and Climacosphenia, were placed in their own Families and Orders but share many characters with Ardissoneaceae, especially growth from a bifacial annulus. Eighteen taxa (11 new species) from Micronesia were compared with the literature and remnant material from Grunow’s Honduras Sargassum sample to address the concepts of Ardissonea and Ardissoneaceae. Phylogenetic and morphological analyses showed three clades within Ardissonea sensu lato: Ardissonea emend. for the double-walled taxa, Synedrosphenia emend. and Ardissoneopsisgen. nov. for single-walled taxa. New species include Ardissonea densistriatasp. nov.; Synedrosphenia bikarensissp. nov., S. licmophoropsissp. nov., S. parvasp. nov., and S. rectasp. nov.; Ardissoneopsis fulgicanssp. nov., A. appressatasp. nov., and A. gracilissp. nov. Transfers include Synedrosphenia crystallinacomb. nov. and S. fulgenscomb. nov. Synedra undosa, seen for the first time in SEM in Grunow’s material, is transferred to Ardissoneopsis undosacomb. nov. Three more genera have similar structure: Toxarium, Climacosphenia and Grunowagogen. nov., erected for Synedra bacillaris and a lanceolate species, G. pacificasp. nov. Morphological characters of Toxarium in our region support separation of Toxarium hennedyanum and T. undulatum and suggest additional species here and elsewhere. Climacosphenia moniligera was not found but we clarify its characters based on the literature and distinguish C. soulonalissp. nov. from it. Climacosphenia elongata and a very long, slender C. elegantissimasp. nov., previously identified as C. elongata, were present along with C. scimiter. Morphological and molecular phylogenetics strongly suggested that all these genera belong in one family and we propose to include them in the Ardissoneacae and to reinstate the Order Ardissoneales Round.
Not going 'pop': the aesthetic criticism of early British Maoism
Authors: Parker Lawrence
Published: September 2022

If people think about Maoist/anti-revisionist groups in countries such as Britain, they are often seduced by an impression of exoticism and the incompatibility of such groups with a more humdrum native left-wing culture. What is also significant about such groups is the depth of their
ideological inheritance from the Soviet-inspired world communist movement. This is particularly clear in relation to such groups' cultural criticism. Cultural products such as folk or pop music tended to be reduced to simplistic class designations (i.e.bourgeois art) and were often ruthlessly
dismissed, sometimes for an apparent propensity to lead to fascism. Maoists called for a more political, communist art as an alternative, focused on serving the struggle for proletarian revolution. It's important to grasp that such criticism wasn't set apart from previous inner-CPGB debates
on cultural issues, where the oppositional left that had been apparent in the party since the Second World War had retained the thrust of the Zhdanov doctrine emphasised by the party majority in the immediate post-war years. This article explores the aesthetic responses of a number of groups
that developed during the first wave of international Maoism in the 1960s and measures them against inner-CPGB differences on art and culture.
Neuromuscular blocking agents and opioids are major risk factors for developing pressure injuries in patients in the intensive care unit
Authors: Lee Su Yeon , Oh Dong Kyu , Hong Sang-Bum , Lim Chae-Man , Huh Jin Won
Published: September 2022

Background/Aims: Patients in the intensive care unit (ICU) are at high risk for developing pressure injuries, which can cause severe complications and even increase the mortality risk. Therefore, prevention of pressure injuries is most important. In this study, we investigated the risk factors of pressure injury development in patients admitted to the ICU.Methods: We retrospectively analyzed patients ages > 18 years admitted to the medical ICU in a tertiary hospital between January and December 2019. We collected patient baseline characteristics, medications received, mechanical ventilation or hemodialysis use, laboratory findings, and date of pressure injury onset and characteristics.Results: We analyzed 666 patients who did not have pressure injuries at ICU admission. Pressure injuries developed in 102 patients (15%). The risk of pressure injury development increased as the administration days for neuromuscular blocking agents (NMBAs; odds ratio [OR], 1.138; p = 0.019) and opioids (OR, 1.084; p = 0.028) increased, and if the patient had problem with friction and shear (OR, 2.203; p = 0.011).Conclusions: The prolonged use of NMBAs and opioids can increase the risk of pressure injury development. Because these medications are associated with immobilization, using both should be minimized and patient early mobilization should be promoted. Among the Braden subscales, “friction and shear” was associated with the development of pressure injuries in ICU patients.
Glyphosate, la « guerre des urines » a bien eu lieu
Authors: Allard-Huver François
Published: September 2022

Nous analysons la « Campagne citoyenne de recherche de glyphosate » organisée entre 2018 et 2020 par l’association « Campagne Glyphosate ». Avec plus de 6 800 prélèvements d’urine à travers toute la France, l’association remet en question l’évaluation des risques sur le glyphosate et l’exposition des populations. Cette action suscite alors une controverse importante qui se traduit par la volonté pour certains acteurs de disqualifier et de semer le doute sur la démarche citoyenne. Par l’analyse d’un triple corpus (entretiens / presse / dispositifs), nous avons observé l’affrontement de différentes formes de savoirs et d’expertises dans l’espace public ainsi que les processus de production du savoir à même de redéfinir les rapports entre science et société, au cœur d’une controverse au long cours.

Video behavior recognition based on actional-structural graph convolution and temporal extension module
Authors: Xu Hui , Kong Jun , Liang Mengyao , Sun Hui , Qi Miao
Published: September 2022

Human behavior recognition has always been a hot spot for research in computer vision. In this paper, we propose a novel video behavior recognition method based on Actional-Structural Graph Convolution and a Temporal Extension Module under the framework of a Spatio-Temporal Graph Convolution Neural Network, which can optimize the spatial and temporal features simultaneously. The basic network framework of our method consists of three parts: spatial graph convolution module, temporal extension module and attention mechanism module. In the spatial dimension, the action graph convolution is utilized to obtain abundant spatial features by capturing the correlations of distant joint features, and the structural graph convolution expands the existing skeleton graph to acquire the spatial features of adjacent joints. In the time dimension, the sampling range of the temporal graph is expanded for extracting the same and adjacent joints of adjacent frames. Furthermore, attention mechanisms are introduced to improve the performance of our method. In order to verify the effectiveness and accuracy of our method, a large number of experiments were carried out on two standard behavior recognition datasets: NTU-RGB+D and Kinetics. Comparative experiment results show that our proposed method can achieve better performance.
Parameter assignment for InVEST habitat quality module based on principal component analysis and grey coefficient analysis
Authors: Wang Shiyun , Liang Xiaonan , Wang Jiaoyue
Published: September 2022

The Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model is a concise approach to evaluate the status of habitat quality for supporting ecosystem management and decision making. Assigning parameters accurately in the InVEST model is the premise for effectively simulating habitat quality. The purpose of this study is to propose an available method for assigning the important parameters in the Habitat Quality module of InVEST. Herein, the methods of principal component analysis (PCA) and grey relational analysis (GRA) were utilized to assign the weights of threat factors and the sensitivity of each habitat type to each threat factor, respectively. Through a case study of the habitat quality of Fuzhou City, we find that using PCA and GRA methods to assign parameters is feasible. Generally, the habitat quality of Fuzhou City in 2015 and 2018 was above the fair suitable level, and the proportion of fair suitable and good suitable habitats was about 83%. The areas with higher habitat quality were mainly concentrated in forest, wetland and grassland ecosystems. The spots with lower habitat quality were scattered all over the main urban areas of districts and counties, and their periphery. GDP per capita and population density were the main factors that affect the habitat quality of Fuzhou City. Narrowing the economic imbalance gap is an important way to reduce population shift and relieve the pressure of the urban environment in economically developed areas. This study is expected to provide an effective method for assigning parameters in the InVEST Habitat Quality Module and support regional ecosystem conservation.
The Association Between Metabolic Syndrome and Colorectal Cancer Risk by Obesity Status in Korean Women: A Nationwide Cohort Study
Authors: Moon Seong-geun , Park Boyoung
Published: September 2022

Objectives: This study aimed to determine the association between metabolic syndrome (MetS) and the incidence of colorectal cancer (CRC) in Korean women with obesity.Methods: Cancer-free women (n=6 142 486) aged 40-79 years, who underwent National Health Insurance Service health examinations in 2009 and 2010 were included. The incidence of CRC was followed until 2018. The hazard ratio (HR) of MetS for the incidence of colon and rectal cancer was analyzed according to body mass index (BMI) categories, adjusting for confounders such as women’s reproductive factors. In addition, the heterogeneity of associations across BMI categories was assessed.Results: Women with MetS were at increased risk of colon and rectal cancer compared to women without MetS (HR, 1.20; 95% confidence interval [CI], 1.16 to 1.23 and HR,1.15; 95% CI, 1.11 to 1.20), respectively. The HR of MetS for colon cancer across BMI categories was 1.12 (95% CI, 1.06 to 1.19), 1.14 (95% CI, 1.08 to 1.20), and 1.16 (95% CI, 1.12 to 1.21) in women with BMIs <23.0 kg/m2, 23.0-24.9 kg/m2, and ≥25.0 kg/m2, respectively. The HR of MetS for rectal cancer across corresponding BMI categories was 1.16 (95% CI, 1.06 to 1.26), 1.14 (95% CI, 1.05 to 1.23), and 1.13 (95% CI, 1.06 to 1.20). The heterogeneity of associations across BMI categories was not significant in either colon or rectal cancer (p=0.587 for colon cancer and p=0.927 for rectal cancer).Conclusions: Women with MetS were at increased risk of colon and rectal cancer. Clinical and public health strategies should be considered for primary CRC prevention with an emphasis on improving women’s metabolic health across all BMI groups.

Published: September 2022

This study analyses the samples collected annually (2012 to 2018) on circalittoral and bathyal soft bottoms (30 to 800 m) by the MEDITS surveys in the northern Alboran Sea (including Alboran Island) and the Gulf of Vera to determine the composition, structure and distribution of decapod crustacean assemblages. A total of 94 decapod crustacean species were identified. Non-metric multidimensional scaling showed depth to be the main factor for distinguishing four main decapod assemblages: the inner shelf (30-100 m depth), outer shelf (101-200 m), upper slope (201-500 m) and middle slope (501-800 m). PERMANOVA analyses revealed further significant depth-related differences between three established geographical sectors of the study area (northern Alboran Sea, Gulf of Vera and Alboran Island). Generalized additive model analyses were used to assess the bathymetrical, geographical and environmental effects on the ecological indices of each assemblage. Results showed that depth and the geographical effect were the main drivers in all cases. Decreases in abundance and increases in species richness, Shannon-Wiener diversity and Pielou’s evenness indices with depth were detected. This study shows the primacy of depth and geographical effect on the distribution of decapod species in the study area, in alignment with findings from other parts of the Mediterranean Sea.
Enhancing onboard post-catch vitality of discard Norway lobster (Nephrops norvegicus) for more sustainable Mediterranean trawl fishery
Authors: García-de-Vinuesa Alfredo , Maynou Francesc , Demestre Montserrat
Published: September 2022

The current European Union fisheries policy encourages improving handling practices to increase the survival of discards. Trawling on the Mediterranean upper slope often generates over 30% of discards of the total catch. Among other species, Nephrops norvegicus juveniles are abundantly returned to the sea, sometimes exceeding 40% of discarded biomass. N. norvegicus discard survival probability has been recently shown to be related to vitality on board and to vary seasonally, being especially low during the summer (0.06). Environmental characteristics (especially, high on-deck temperature in summer) make it necessary to improve vitality on board in order to increase discard survival. We therefore tested new discard handling methodologies for a Mediterranean mixed trawl fishery, with N. norvegicus as the target species. The results showed a survival rate on board higher than 0.8 resulting from vitality status improvements achieved by immersing N. norvegicus in cooled seawater on board during the catch selection and discard time. The implementation of this method would make an important contribution to more sustainable Mediterranean trawl fisheries.

The aim of this article is to map the current state of knowledge on the digital competences of higher education professors in the European context through a scoping review. The initial search in resulted in 1,568 publications, which, after applying the selection criteria, resulted in the inclusion of 14 publications. The content analysis showed that the digital tools made available by the intuitions are widely known by the professors, although they have little use. A broad use of the LMS was evidenced, but more specifically to administrative activities than to activities connected with the teaching and learning process. There was also a positive relationship between the level of digital competences and the pedagogical approach adopted by professors (focus on the construction of knowledge by the students, development of open education resources) as well as the participation in research projects. Teachers’ training was pointed out as a relevant topic and the literature analysed referred that this should be preceded by a rigorous analysis of the professors’ digital competence levels so that this process can be carried out in the most personalized way possible.

Construction of the Interactive Educational Knowledge Graph and Classification of Student Groups
Authors: Sun Hai
Published: September 2022

The attributes of the knowledge nodes in the interactive educational knowledge graph need to cater to students’ online learning preferences, so understanding the composition and learning preferences of students in the online learning process is helpful to the development of more targeted learning paths. Currently, there are few existing research results on knowledge graph embedding methods based on students’ interaction with respect to knowledge points, student group composition and their learning preferences. To this end, this paper studies the construction of an interactive educational knowledge graph and the classification of student groups. First, a knowledge recommendation idea was proposed based on the classification of student groups. Through the three types of interaction behaviors - human-computer, teacher-student, and student-student interactions that occur on the online learning platform, the depth of students’ interactions with respect to the knowledge points in the interactive educational knowledge graph was characterized. The online learning effects of students were quantified by the interactive achievement of knowledge points mastered by students and the weights of knowledge points which represent their importance. Then, the effects of the differences in the interactions of students with respect to different knowledge points on the stability of the similarity prediction of students’ learning preferences were explored, and based on the analysis results, students were classified into groups. The experimental results verified the effectiveness of the proposed model.
Emission, propagation, and reflection of light as mechanical phenomena: General considerations
Authors: Filipescu Filip Dambi
Published: September 2022

The emission, propagation, and reflection of light as mechanical phenomena are based on the behavior of balls, at the limit when their mass is zero, emitted by a balls source and reflected by a rigid wall in an elastic collision. Light as a wave or particle is a massless entity. Therefore,
applying the kinematics behavior of the massless balls to light is natural. Consequently, the kinematics of light depends on its kinetics of electromagnetic nature and its kinematics of mechanical nature in interactions with the matter as emission and reflection. By applying the emission,
propagation, and reflection of light as mechanical phenomena in a vacuum of the frame at absolute rest, this study derives the velocities of a wavefront of light reflected by a fixed and moving mirror when the light comes from a fixed and moving source. The derived velocities apply to the
modified Michelson interferometer, employed independently by Tomaschek and Miller in their experiments.

space, it can be static. This does neither violate wave-particle duality nor uncertainty relationship. Dirac equation correctly describes physical reality, while Schrödinger equation does not when it is not the nonrelativistic approximation of Dirac equation with a certain model. The
conclusion that there is no zero-point energy in the form of    ω / 2   is applied to
solve the famous cosmological constant problem for massive particles.

Laryngeal pathologies resulting in voice disorders are normally diagnosed using invasive methods such as rigid laryngoscopy, flexible nasopharyngo-laryngoscopy and stroboscopy, which are expensive, time-consuming and often inconvenient to patients. Automatic Voice Disorder Detection (AVDD) systems are used for non-invasive screening to give an indicative direction to the physician as a preliminary diagnosis. Deep neural networks, known for their superior discrimination capabilities, can be used for AVDD Systems, provided there are sufficient samples for training. The most popular datasets used for developing AVDD systems lack sufficient samples in several pathological categories. Leukoplakia — a premalignant lesion, which may progress to carcinoma unless detected early — is one such pathology. Data augmentation is a technique used in deep learning environments to increase the size of the training datasets which lack sufficient samples for effective data analysis and classification. This study aims at investigating the performance enhancement of a deep learning-based AVDD system through a novel time domain data augmentation technique named ‘TempAug’. This method segments each data sample into short voice segments, so as to get multiple data from each sample, thereby generating a larger database (augmented database) for training a deep learning model. A deep neural network model, Long Short-Term Memory (LSTM) with Short Term Fourier Transform (STFT) coefficients as input features for classification, was used in this study for the detection of the voice disorder Leukoplakia. A series of experiments were done to investigate the effect of data augmentation and to find the optimum duration for segmentation. Based on experimental results, a detection strategy was developed and evaluated using an AVDD system, which gave an accuracy of 81.25%. The percentage increase in accuracy was found to be 46.9% with respect to the accuracy obtained for unaugmented data.

A evasão universitária tem sido um fenômeno nas instituições latino-americanas, ocasionando impactos no contexto educacional, político, econômico e social. Este artigo tem por objetivo analisar quais práticas curriculares, pedagógicas e de integração universitária vêm sendo desenvolvidas acerca da permanência estudantil nas universidades latino-americanas. Para isso, foi realizada uma pesquisa bibliográfica, denominada Estado do Conhecimento, na qual foram analisados 156 trabalhos publicados nas edições de 2016 a 2018 da Conferência Latino-Americana sobre o Abandono no Ensino Superior – (CLABES). Após sistematizar e analisar os dados, foram elaboradas três categorias: Estudantes; Docentes; Cultura Institucional Universitária. A partir desta pesquisa, percebeu-se que as instituições latino-americanas têm desenvolvido programas de permanência integrados à cultura institucional para que tais ações sejam contributos à experiência universitária de forma permanente. Nesse sentido, destaca-se que as estratégias de gestão acadêmica, as inovações e as adaptações nas metodologias de ensino, bem como o engajamento dos estudantes no seu processo formativo, fazem-se necessárias, sendo estratégias articuladas e eficazes na promoção da permanência universitária e na redução dos índices de evasão.

PERCEPÇÕES DOCENTES SOBRE POTENCIALIDADES DO TRABALHO PEDAGÓGICO COM IMAGENS NO ENSINO-APRENDIZAGEM DA GEOGRAFIA ESCOLAR
Authors: Lopes Willian Falcão , Sitja Liége Maria Queiroz
Published: September 2022

O presente artigo investigou as percepções docentes sobre as possíveis transformações qualitativas no ensino-aprendizagem da geografia por meio do trabalho pedagógico com imagens e as possibilidades de aproximação entre esse trabalho e as vivências dos estudantes. Para seu desenvolvimento, foram feitas entrevistas fenomenológicas com seis docentes de geografia da Rede Pública de Educação da Bahia, em Salvador. Os resultados permitem afirmar que as percepções docentes revelam ser o trabalho pedagógico com imagens um elemento potencializador de “conhecimentossignificação” uma vez que as aberturas das imagens convocam os estudantes a envolverem-se em maior profundidade com os conteúdos da geografia escolar e com os próprios processos de aprendizagem. Ademais, o trabalho pedagógico com imagens possibilita aos docentes uma prática de ensino problematizante, sensível, inovadora, dinâmica e, principalmente, relacionada à vida dos estudantes. Esse trabalho impulsiona o docente e os estudantes a desenvolverem competências cognitivas, sociais e afetivas, possibilitando tanto profundidade para criar imagens quanto para lê-las criticamente. O trabalho pedagógico com imagens proporciona contato com sensações e vivências dos estudantes, gerando uma maior aproximação e interação entre esses e os docentes. Além disso, quando articuladas com os conteúdos da geografia escolar, essas sensações proporcionam que a aprendizagem dos estudantes se torne mais experiencial e marcante em suas memórias.

Published: September 2022

O objetivo deste artigo é defender a proposta da educação inclusiva como possibilidade de enfrentar dois tipos de violência escolar: bullying e preconceito. Tem como referencial a Teoria Crítica. Parte da hipótese de que escolas com maior grau de inclusão escolar teriam menos situações de violência e apresenta dados de pesquisa de duas entre cinco escolas estaduais de Guarulhos para testá-la: a de maior e a de menor grau de inclusão. Aplicaram-se dois instrumentos para identificação do grau de inclusão escolar e escalas a 83 alunos dos nonos anos para verificar a ocorrência de bullying, do preconceito e do autoritarismo dos alunos. Os resultados indicam que a escola de maior grau de inclusão escolar obteve menor grau de autoritarismo e da prática da discriminação entre alunos; já a frequência de bullying permaneceu semelhante nas duas escolas. O estudo conclui que o convívio com a diferença, propício às propostas de educação inclusiva, oferece possibilidades para refletir sobre os impulsos agressivos expressos pelo preconceito e, assim, refreá-los. Já o bullying parece necessitar de medidas para o seu enfrentamento que vão além da proposta de inclusão.

Este ensaio é uma reflexão sobre algumas inquietações acerca dos processos de ensino e aprendizagem em Artes Visuais, sobretudo no modo como tais processos se encontram em “deslocamento” diante dos efeitos da maior crise sanitária do século XXI. Diante das medidas de enfrentamento ao surto da Covid-19, tem-se estabelecido novas formas de interação, implicando mudanças profundas no contexto educacional. Nessa perspectiva, buscou-se traçar algumas possibilidades e flutuações a partir das imagens de referência das mídias sociais e no modo como elas, diferentemente dos processos legitimados pela escola, se configuram como espaços de educação em Artes Visuais, especialmente em tempos de pandemia. Assim, as reflexões apresentadas por este trabalho estão inseridas no campo da Cultura Visual, ao conceber as imagens do campo virtual como territórios culturais de aprendizagem.
O CURRÍCULO NA EDUCAÇÃO INFANTIL A PARTIR DA BNCC
Authors: Badaró Emilly Souza Coelho , Almeida Marcelo Nocelle de
Published: September 2022

O Brasil estabeleceu uma base curricular comum para a Educação Básica e, com isso, todas as escolas públicas e privadas do país receberam um novo desafio de construir e desenvolver na prática currículos contemplando uma lista de habilidades e direitos exigidos por essa normativa, acrescentando ainda temas transversais contemporâneos e elementos da realidade local. Há em curso, porém, outra demanda que não veio de fora da escola e que também se constitui um desafio: a interdisciplinaridade. A perspectiva da abordagem interdisciplinar na escola se vincula à ideia de que o trabalho cooperativo dos professores e o estudo integrado de problemas concretos podem ajudar a diminuir a tradicional forma descontextualizada e fragmentada de apresentar os conteúdos e facilitar o processo ensino-aprendizagem. Como a Educação Infantil não ficou de fora da base nacional, desenvolveremos neste estudo uma reflexão sobre a ocorrência de riscos de fragmentação do currículo organizado para as crianças pequenas. A discussão parte da análise documental dessa nova normativa e de pesquisas bibliográficas, detalhando os Campos de Experiências e buscando entender se existem conexões ou distanciamento entre seus elementos constitutivos.

Varicella zoster virus (VZV) is a Herpesviridae family double-stranded DNA virus that only affects humans. The first clinical manifestation appears to be varicella, typical of childhood. VZV, on the other hand, becomes latent in ganglion neurons throughout the neuroaxis after primary infection. The VZV reactivates and travels along peripheral nerve fibers in the elderly and immunocompromised individuals, resulting in Zoster. It can, however, spread centrally and infect cerebral and extracranial arteries, resulting in vasculopathy, which can lead to transient ischemic attacks, strokes, aneurysms, cavernous sinus thrombosis, giant cell arteritis, and granulomatous aortitis. Although the mechanisms of virus-induced pathological vascular remodeling are not fully understood, recent research indicates that inflammation and dysregulation of ligand-1 programmed death play a significant role. Few studies, on the other hand, have looked into the role of VZV in cardiovascular disease. As a result, the purpose of this review is to examine the relationship between VZV and cardiovascular disease, the efficacy of the vaccine as a protective mechanism, and the target population of heart disease patients who could benefit from vaccination.
