Detecting Atmospheric Molecules of Nontransiting Temperate Terrestrial Exoplanets Using High-resolution Spectroscopy in the Mid-infrared Domain
Authors: Fujii Yuka , Matsuo Taro
Published: March 2021

Motivated by the development of high-dispersion spectrographs in the mid-infrared (MIR) range, we study their application to the atmospheric characterization of nearby nontransiting temperate terrestrial planets around M-type stars. We examine the detectability of CO2, H2O, N2O, and O3 features in high-resolution planetary thermal emission spectra at 12–18 μm assuming an Earth-like profile and a simplified thermal structure. The molecular line width of such planets can be comparable to or broader than the Doppler shift due to the planetary orbital motion. Given the likely difficulty in knowing the high-resolution MIR spectrum of the host star with sufficient accuracy, we propose observing the target system at two quadrature phases and extracting the differential spectra as the planetary signal. In this case, the signals can be substantially suppressed compared with the case where the host star spectrum is perfectly known, as some parts of the spectral features do not remain in the differential spectra. Despite this self-subtraction, the CO2 and H2O features of nearby (≲5 pc) systems with mid-/late-M host stars would be feasible with a 6.5 m class cryogenic space telescope, and orbital inclination could also be constrained for some of them. For CO2 and N2O in a 1 bar Earth-like atmosphere, this method would be sensitive when the mixing ratio is 1–103 ppm. The detectability of molecules except O3 is not significantly improved when the spectral resolution is higher than

, although the constraint on the orbital inclination is improved. This study provides some benchmark cases useful for assessing the value of MIR high-resolution spectroscopy in terms of characterization of potentially habitable planets.
Circumgalactic Mg ii Emission from an Isotropic Starburst Galaxy Outflow Mapped by KCWI

Published: March 2021

We present spatially resolved spectroscopy from the Keck Cosmic Web Imager (KCWI) of a star-forming galaxy at z = 0.6942, which shows emission from the Mg ii
λ
λ2796, 2803 doublet in the circumgalactic medium (CGM) extending ∼37 kpc at 3σ significance in individual spaxels (1σ detection limit 4.8 × 10−19 erg s−1 cm−2 arcsec−2). The target galaxy, selected from a near-UV spectroscopic survey of Mg ii line profiles at 0.3 < z < 1.4, has a stellar mass log (M
*/M
⊙) = 9.9, a star formation rate of 50 M
⊙ yr−1, and a morphology indicative of a merger. After deconvolution with the seeing, we obtain 5σ detections of Mg ii line emission extending for ∼31 kpc measured in 7-spaxel (1.1 arcsec2) apertures. Spaxels covering the galaxy stellar regions show clear P Cygni−like emission/absorption profiles, with the blueshifted absorption extending to relative velocities of v = −800 km s−1; however, the P Cygni profiles give way to pure emission at large radii from the central galaxy. We have performed 3D radiative transfer modeling to infer the geometry and velocity and density profiles of the outflowing gas. Our observations are most consistent with an isotropic outflow rather than biconical wind models with half-opening angles ϕ ≤ 80°. Furthermore, our modeling suggests that a wind velocity profile that decreases with radius is necessary to reproduce the velocity widths and strengths of Mg ii line emission profiles at large circumgalactic radii. The extent of the Mg ii emission we measure directly is further corroborated by our modeling, where we rule out outflow models with extent <30 kpc.

We present the analysis of X-ray observations of the black hole binary 4U 1630−47 using relativistic reflection spectroscopy. We use archival data from the Rossi X-ray Timing Explorer, Neil Gehrels Swift Observatory, and Nuclear Spectroscopic Telescope Array observatories, taken during different outbursts of the source between 1998 and 2015. Our modeling includes two relatively new advances in modern reflection codes: high-density disks, and returning thermal disk radiation. Accretion disks around stellar-mass black holes are expected to have densities well above the standard value assumed in traditional reflection models (i.e., n
e ∼ 1015 cm−3). New high-density reflection models have important implications in the determination of disk truncation (i.e., the disk inner radius). This is because one must retain self-consistency in the irradiating flux and corresponding disk ionization state, which is a function of disk density and system geometry. We find that the disk density is n
e ≥ 1020 cm−3 across all spectral states. This density, combined with our constraints on the ionization state of the material, implies an irradiating flux impinging on the disk that is consistent with the expected theoretical estimates. Returning thermal disk radiation—the fraction of disk photons that bend back to the disk producing additional reflection components—is expected predominantly in the soft state. We show that returning radiation models indeed provide a better fit to the soft-state data, reinforcing previous results that show that in the soft state, the irradiating continuum may be blackbody emission from the disk itself.

Published: March 2021

The Lyman-alpha (Lyα) line of neutral hydrogen at 121.6 nm is by far the brightest emission line in the vacuum ultraviolet spectral range of the Sun. The emission at this line could be a major energy input to the upper layers of the Earth’s atmosphere, strongly impacting the geospace environment. The Geostationary Operational Environmental Satellite (GOES) series, starting with GOES-13, began to carry a multichannel Extreme UltraViolet Sensor (EUVS) with one channel (E-channel) targeting the Lyα line. In the present work, we produce a Lyα flare catalog from the GOES-15/EUVS-E data between 2010 April 8 and 2016 June 6 with an automatic flare detection algorithm. This algorithm is designed to search events at various scales and find their real start and end times. Based on the obtained flare list, statistics on the temporal behavior such as the duration, rise, and decay times, and the event asymmetries of Lyα flares is presented. On average (defined by the median of the distributions), the duration, rise and decay times of the flares were estimated to be 20.8 minutes, 5.6 minutes, and 14.2 minutes, respectively. We also discuss the frequency distributions of the peak flux and the fluence of Lyα flares, both of which reveal power-law behaviors with power-law indices of 2.71 ± 0.06 and 2.42 ± 0.06, respectively, implying that more flares are accumulated at small scales and these small-scale events play an important role in explaining the violent solar energy release.

Published: March 2021

We studied the effects of the aspheric transition zone on the optical wavefront aberrations, corneal surface displacement, and stress induced by the biomechanical properties of the cornea after conventional laser in situ keratomileusis (LASIK) refractive surgery. The findings in this study can help improve visual quality after refractive surgery. Hyperopia correction in 1-5D was simulated using five types of aspheric transition zones with finite element modeling. The algorithm for the simulations was designed according to the optical path difference. Wavefront aberrations were calculated from the displacements on the anterior and posterior corneal surfaces. The vertex displacements and stress on the corneal surface were also evaluated. The results showed that the aspheric transition zone has an effect on the postoperative visual quality. The main wavefront aberrations on the anterior corneal surface are defocus, y-primary astigmatism, x-coma, and spherical aberrations. The wavefront aberrations on the corneal posterior surface were relatively small and vertex displacements on the posterior corneal surface were not significantly affected by the aspheric transition zone. Stress analysis revealed that the stress on the cutting edge of the anterior corneal surface decreased with the number of aspheric transition zone increased, and profile #1 resulted in the maximum stress. The stress on the posterior surface of the cornea was more concentrated in the central region and was less than that on the anterior corneal surface overall. The results showed that the aspheric transition zone has an effect on postoperative aberrations, but wavefront aberrations cannot be eliminated. In addition, the aspheric transition zone influences the postoperative biomechanical properties of the cornea, which significantly affect the postoperative visual quality.
Strategy of boundary discretization in numerical simulation of laser propagation in skin tissue with vascular lesions
Authors: Jia Hao , Chen Bin , Li Dong , Jin Yuzhen
Published: March 2021

Understanding light propagation in skin tissues with complex blood vessels can help improve clinical efficacy in the laser treatment of cutaneous vascular lesions. The voxel-based Monte Carlo (VMC) algorithm with simple blood vessel geometry is commonly used in studying the law of light propagation in tissues. However, unavoidable errors are expected in VMC because of the zigzag polygonal interface. A tetrahedron-based Monte Carlo with extended boundary condition (TMCE) solver is developed to discretize complex tissue boundaries accurately. Tetrahedra are generated along the interface, resulting in a polyhedron approximation to match the real interface. A comparison between TMCE and VMC shows neglected differences in the overall distribution of energy deposition of different models, but poor adaptability of the curved tissue interface in VMC leads to a higher energy deposition error than TMCE in a mostly deposited region in blood vessels. Replacing the real blood vessel with a cylinder-shaped vessel shows an error lower than that caused by VMC. Statistical significance analysis of energy deposition by TMCE shows that mean curvature has stronger relationship with energy deposition than the Gaussian curvature, which indicates the importance of this geometric parameter in predicting photon behavior in vascular lesions.
Créer sa propre histoire : Alternance des voix et discours métanarratif dans La vie commence de Stefan Casta
Authors: Jarl Ireman Annelie
Published: March 2021

Cet article propose une analyse du discours narratif et métanarratif du roman La vie commence de Stefan Casta, qui permet de constater que l’œuvre s’inscrit dans une nouvelle tradition au sein de la littérature de jeunesse, caractérisée par sa forme expérimentale. L’alternance des voix, les changements de points de vue et de temps, ainsi que la structure influencée par le cinéma rendent le livre exigeant. Le narrateur principal ne fait pas que raconter son histoire, complétée par d’autres voix, il la transforme en roman. Grâce à cette création littéraire, Viktor évolue et trouve finalement le courage de commencer réellement sa vie. Son existence se confirme par le roman qu’il écrit, c’est en cela qu’il se montre héroïque. Le roman de Casta permet aux jeunes lecteurs de s’identifier eux-mêmes, notamment grâce au style accessible et aux références au cinéma, tandis que le discours narratif complexe attire des lecteurs plus expérimentés. C’est cette double-adresse qui définit avant tout la littérature de jeunesse suédoise d’aujourd’hui.
Elin Wägner, une pionnière de la prise de conscience écologique

Published: March 2021

Si Elin Wägner (1882-1949) est une figure bien connue en Suède, tant pour ses activités de journaliste engagée sur de nombreux fronts, dont celui du pacifisme, que comme romancière, elle demeure totalement méconnue en France. Il s’agit ici de faire connaissance avec elle et d’étudier une pensée novatrice, en avance sur son temps. Cet article présente l’évolution de la réflexion d’Elin Wägner, dont la conviction pacifiste l’amènera à préconiser une démarche de respect de notre mère la terre. Elle préfigurera ainsi la naissance du mouvement écologique en Suède, mais également celle d’une pensée éco-féministe.
La dimension temporelle de l’égalité : les réformes scolaires en Suède (1946-2000)
Authors: Wedin Tomas
Published: March 2021

Selon l’interprétation dominante dans l’historiographie éducative, le système éducatif suédois a connu une rupture idéologique vers 1990. À rebours de cette tradition, cet article met en évidence une certaine continuité entre la pensée des années 1970, soit la phase culminante de l’ordre égalitaire de l’après-guerre, et les réformes des années 1990, souvent considérées comme la manifestation d’une rupture avec la doctrine éducative préexistante. Afin de faire ressortir les lignes de continuité, j’analyse ici comment la manière dont l’idéal d’égalité a été mobilisé dans le contexte des politiques éducatives a influencé la référence au passé, au présent et au futur en tant qu’horizons de l’action collective. Je soutiens que le présent est devenu de plus en plus l’horizon de référence au détriment autant du passé que du futur, et que la radicalisation de l’aspiration à l’égalité a renforcé cette transformation. En concluant, je soutiens que les efforts dans le sens de la démocratisation du système éducatif ont paradoxalement sapé sa légitimité fondée sur un ordre collectif.
The Impact of Performance Assessment System on Employee Commitment: A Study among Executive Officers of State-Owned Commercial Banks in Sri Lanka
Authors: Kumari D. A. T. , Medis Ajith
Published: March 2021

Performance management is a much broader and a complicated function of HR, as it encompasses activities such as joint goal setting, continuous progress review and frequent communication, feedback and coaching for improved performance, implementation of employee development programs and rewarding achievements. Performance management can be regarded as a systematic process by which the overall performance of an organization can be improved by improving the performance of individuals within a team framework. It is a means for promoting superior performance by communicating expectations, defining roles within a required competence framework, and establishing achievable benchmarks. As end results, the performance appraisal positively affects to the employee commitment and it will lead to achieving corporate objectives. However, there is a public opinion about a poor performance management system in public sector organizations. Accordingly, some researchers argue that performance management of public sector commercial banks is poorer than private sector commercial banks in the Sri Lankan context. Hence, this paper focuses on the assessment of the influence of the current performance management system adopted by major state-owned commercial banks on job commitment of their executive employees. The sample for this study was drawn from executive grade employees who are working at Peoples Bank and Bank of Ceylon and data were collected by using self-administrated questionnaire. Altogether 350 questionnaires were distributed by email and 208 completed questionnaires were taken in for final analysis. The PLS based SEM was employed to measure the impact of the exogenous variable on the endogenous variable based on the Smart PLS-3. The results revealed that among the set of determinants, career development, is the most significant determinant of employee commitments among executive officers of state-owned commercial banks in Sri Lanka. Further, it was revealed that, alignment with organizational goals, is the least significant determinant of employee commitments among executive officers of state-owned commercial banks in Sri Lanka.

The aim of this study was to assess the role of climate variability on the incidence of dengue fever (DF), an endemic arboviral infection existing in Jakarta, Indonesia. The work carried out included analysis of the spatial distribution of confirmed DF cases from January 2007 to December 2018 characterising the sociodemographical and ecological factors in DF high-risk areas. Spearman’s rank correlation was used to examine the relationship between DF incidence and climatic factors. Spatial clustering and hotspots of DF were examined using global Moran’s I statistic and the local indicator for spatial association analysis. Classification and regression tree (CART) analysis was performed to compare and identify demographical and socio-ecological characteristics of the identified hotspots and low-risk clusters. The seasonality of DF incidence was correlated with precipitation (r=0.254, P<0.01), humidity (r=0.340, P<0.01), dipole mode index (r= –0.459, P<0.01) and Tmin (r= –0.181, P<0.05). DF incidence was spatially clustered at the village level (I=0.294, P<0.001) and 22 hotspots were identified with a concentration in the central and eastern parts of Jakarta. CART analysis showed that age and occupation were the most important factors explaining DF clustering. Areaspecific and population-targeted interventions are needed to improve the situation among those living in the identified DF high-risk areas in Jakarta.

Published: March 2021

Background

In the COVID-19 era, efforts are being made to increase awareness among students and enhance best practices to mitigate the outbreak. To that end, the overarching aims of this study were to understand students’ attitude toward and knowledge of COVID-19 and examine the predictors of their attitude toward hand hygiene.

Design and methods

This cross-sectional survey study, conducted in Saudi Arabia, enrolled interns from diverse healthcarerelated fields. The questionnaire was divided into three sections: sociodemographic data, knowledge of COVID-19, and attitude toward hand hygiene. The data was expressed as median and interquartile range (IQR).

Results

In all, 371 responses were analyzed. The median knowledge score was 20, which was considered good. There were no statistically significant differences across age, hospital setting, or gender. Of the 254 respondents who had attended an educational session, 167 (65%) had a good knowledge score and 83 (33%) had a moderate score, compared with only four (2%) who had a poor score. The cumulative median score of the respondents’ attitudes was 6 (IQR [2]), which reflects a suboptimal attitude - only 38 (22%) reported a good attitude. The predicted effect of knowledge on attitude (good/suboptimal) was statistically significant (p=0.02) using univariate logistic regression.

Conclusions

The results suggest a strong need to encourage the current training program that targets hand hygiene practices among students in healthcare-related fields, especially prior to the internship year.

Published: March 2021

Depressive symptoms in adolescence have been a subject of considerable controversy in terms of their nature, severity and identification. The aim of the study was to investigate the possible association between weight status and depressive symptoms among 18 year-old Greek adolescents. A cross-sectional study design was used. The study population consisted of 200 students of the University of Athens who fulfilled the following criteria: age 18 years, absence of clinical depression, no history of hospitalization in a mental institution, no history of alcohol abuse. Weight status was assessed by Body Mass Index (BMI) (kg/m2) and calculated from weight and height measurements. Severity of depressive symptoms was assessed by Centre for Epidemiologic Studies-Depression Scale (CES-D). In univariate analysis, CES-D score was significantly associated with adolescents’ gender and BMI. The multivariate analysis showed that CES-D score was negatively related to BMI even after controlling the confounding effect of gender (P=0.018, B=-0.378). Depressive symptoms are related to weight status of adolescents.

We herein used MAZ51 to inhibit lymphangiogenesis and aimed to clarify the effect of inhibition of lymphangiogenesis on wound healing. BALB/c male mice were divided into two groups: the control group which was injected the dimethyl sulfoxide (DMSO), the experiment group was injected MAZ51 in the DMSO. All wounds were observed for 15 days and the wound areas were measured. Tissue samples were harvested on day 3, 7, 9, 11, 13 and 15, and subjected to immunostaining of blood vessels and lymphatic vessels. There are no significant differences between two groups in the wound area, the number of blood vessels and lymphatic vessels. The number of blood vessels peaked on day 7 in both groups as with previous studies, while the number of lymphatic vessels peaked on 13 or 15 in both groups. This result revealed delayed lymphangiogenesis in comparison with previous studies. The wound healing process in the control and experiment groups were similar, but both groups seemed delayed lymphangiogenesis comparing with previous studies. Injections of MAZ51 or/and DMSO did not affect angiogenesis, while they may affect lymphangiogenesis.

Published: March 2021

Aims and Objective:

The assessment of volumetric and dosimetric changes in the head-and-neck cancer during fractionated radiotherapy by intensity-modulated radiotherapy (IMRT) technique.

Materials and Methods:

A single-center prospective observational hospital-based study with a sample size of 20 cases of the head-and--neck squamous cell carcinoma over 1 year treated with chemoradiotherapy 66–70 Gy/33–35#@2 Gy/fraction with weekly cisplatin 35 mg/m 2. After contouring of target volumes (TVs) and organs at risk (OARs) in initial computed tomography (CT) scan, all patients were planned and treated by the IMRT technique. We re-delineated the TVs and OARs in the second (CT15#) and third (CT30#) planning CT scan, and the initial plan was implemented in the re-CT scan dataset with the same optimization and doses. The volumetric and dosimetric changes during fractionated radiotherapy of TVs and OARs were evaluated and compared. Nonparametric Wilcoxon–signed-rank test was used to compare the means between each plan.

Results:

For all 20 patients, plans were compared for volumetric and dosimetric parameters on repeat CT scans. The mean variation in gross tumor volume (GTV) and planning TV (PTV) was significant after 15 and 30 fractions of radiotherapy. On dosimetric evaluation, there was a significant increase in doses to GTV and OARs (parotid, spinal cord, and cochlea) with a significant P value. However, doses to the OARs were not exceeded the maximum tolerance limit.

Conclusion:

This prospective single-center study concluded that two repeat imaging, along with re-planning improved TV coverage and decreased doses to the normal tissue. Larger studies with more sample sizes are required to set the criteria for replanning.
IMPACT OF INFORMATION TECHNOLOGIES’ INVESTMENTS ON THE PROFITABILITY OF TUNISIAN BANKS: PANEL DATA ANALYSIS
Authors: Romdhane Syrine Ben
Published: March 2021

This study examines the relationship between Information Technology investment and the profitability of Tunisian banks, via static and dynamic panel regression models. Our study focused on 15 Tunisian banks for 19 years (2001-2019). To assess the profitability of these banks, three measures were used: two traditional accounting ratios and net interest margin. Our research has shown the importance of the role played by IT in Tunisian banks since IT investments improve their profitability. This finding contradicts the “Productivity Paradox” that high IT investments are not associated with better performance. Indeed, Tunisian banks are acting on their size to boost their performance, and the more the banks take the risk by granting more loans, the more profitable they are by increasing their Return on Assets. Finally, public banks are more profitable than private banks when considering their net interest margin.

Underwater Acoustic Localization Based on IR-GCC-PHAT in Reverberant Environments
Authors: Yoshizawa Shingo
Published: March 2021

This paper presents a method of underwater acoustic localization in reverberant environments. Time difference of arrival (TDOA) measurement algorithm is a key technology for estimating direction of arrival (DOA) of an underwater sound source. In strong multipath interference, the pseudo-peaks in a correlation function disturb the detection of a correct time position and lead to a large TDOA measurement error. The proposed algorithm computes a time difference by taking cross-correlation of two impulse responses and improves robustness to multipath interference. The comparison of TDOA algorithms is done by evaluating the position accuracy of underwater sound source in both simulation and experiment.

Published: March 2021

Introduction: Intra-operative blood pressure monitoring in morbidly obese patients using standard non-invasive blood pressure (NIBP) oscillometric technique with upper arm cuffing is often inaccurate. Invasive arterial blood pressure (IABP) monitoring is the gold standard but is not without complications. The purpose of this study was done to assess the degree of agreement between the forearm and upper arm NIBP with the IABP during laparoscopic bariatric surgery.

Patients and Methodsm The study was conducted in our university hospital. A total of 36 morbidly obese patients undergoing laparoscopic bariatric surgery were studied. The radial artery was cannulated for IABP monitoring on one upper limb while NIBP monitoring was done on the contralateral upper arm and forearm. The NIBP and its corresponding IABP readings were recorded at selected time points at 10 minutes post-induction; 5, 15, and 30 minutes post-insufflation and 15 minutes post- exsufflation.

Results: The mean arterial pressure (MAP) has narrower limits of agreement compared to the systolic blood pressure (SBP) and diastolic blood pressure (DBP) for each method of measurement used. Forearm NIBP showed better agreement with IABP compared to upper arm NIBP. Repeated measures ANOVA showed a similar pattern of changes in SBP, DBP, and MAP measured by NIBP and IABP during the surgery.

Conclusion: Similar patterns of blood pressure changes were observed with IABP, upper arm, and forearm NIBP measurements at all time points. The forearm NIBP showed better agreement to IABP as compared to upper arm NIBP and may be adequate to monitor patterns of blood pressure changes during laparoscopic bariatric surgery.

The on-line secondary path modeling of an ANC systems is the most relevant issue. Currently there are algorithms to obtain fast convergence, adequate stability and minimum error. In this article, the properties of these algorithms are analyzed, as well as the architectures for their possible implementation in hardware. The performance comparison is carried out with behavioral simulation, and its suitability for active noise cancellation is evaluated. Based on the results of the analysis, a new algorithm is proposed, suitable for its implementation in hardware. The results obtained present an attenuation of the order of -31dB, which is the highest attenuation reported so far

"Optical scanning has proven to be advantageous to objectively assess the severity of chest wall deformities and the effectiveness of its treatment. By potentially eliminating the need for computed tomography (CT) scanning and superseding manual measurements that are subject to errors, a system that utilizes optical scanning presents great value to patients and practitioners. This work aims to investigate and evaluate the performance of two off-the-shelf optical scanning sensors in the context of their utility and accuracy to measure the severity of chest wall deformities. An in-vitro experiment and a human study are conducted utilizing both sensors to collect data and report the findings."

"The awareness of market trends becomes relevant for a broad number of market branches, in particular the more they are challenged by the digitalization. Trend analysis solutions help business executives identifying upcoming trends early. But solid market analysis takes their time and are often not available on consulting or strategy discussions. This circumstance often leads to unproductive debates where no clear strategy, technology etc. could be identified. Therefore, we propose a mobile visual trend analysis approach that enables a quick trend analysis to identify at least the most relevant and irrelevant aspects to focus debates on the relevant options. To enable an analysis like this, the exhausting analysis on powerful workstations with large screens has to adopted to mobile devices within a mobile behavior. Our main contribution is the therefore a new approach of a mobile knowledge cockpit, which provides different analytical visualizations within and intuitive interaction design."

Published: March 2021

Este trabalho tem como proposta apresentar questões relacionadas aos jogos e as brincadeiras no processo de desenvolvimento infantil e tem como ponto central “os jogos e as brincadeiras e suas contribuições no processo de desenvolvimento infantil” e como objetivo geral, analisar as contribuições dos jogos e das brincadeiras no processo de desenvolvimento infantil bem como a aprendizagem inclusa nesse processo. Para atingir tal objetivo, planejou-se a divisão do trabalho em duas etapas: pesquisa bibliográfica cuja finalidade é colocar o pesquisador em contato com o que já se produziu e registrou a respeito do seu tema de pesquisa com base em autores como Oliveira (2000), Kishimoto (1997, 2000, 2003), Vygotski (1998), entre outros; e realizou-se uma pesquisa empírica tendo como sujeitos 05 (seis) professores que trabalham na área de Educação Infantil e/ou que estão no último ano de formação acadêmica aos quais poderemos encontrá-los em escolas públicas ou privadas e em universidades/faculdades. Os resultados desses estudos nos permitiram entender que o brincar na educação infantil possui um papel fundamental na conquista da autonomia e aprendizagem da criança e que o lúdico torna-se um instrumento essencial para a obtenção do conhecimento das crianças se caracteriza por proporcionar uma aprendizagem mais prazerosa e satisfatória e uma melhor compreensão não apenas dos conteúdos ministrados em ambiente escolar, mas também da realidade que a cerca.
Empreendedorismo e o mundo do trabalho: o papel do professor na formação de jovens
Authors: De Freitas Marta Bramuci
Published: March 2021

O Estado neoliberal vem atribuindo na contemporaneidade, crescente importância ao empreendedorismo e delegando ao trabalhador o compromisso de intervenção nas questões sociais. Este trabalho tem por objetivo apresentar um relato da experiência realizada por esta docente por meio da exposição e debate sobre o tema empreendedorismo, as relações de trabalho, o dever do Estado e o papel do professor diante desse tema envolvendo questões tão complexas. Para tanto, buscou-se tanto na intervenção, quanto na elaboração deste trabalho, além de apresentar a experiência, constituir-se-um referencial teórico baseado nas variáveis sobre o ensino de empreendedorismo partindo de uma visão crítica sobre o mundo do trabalho e o papel do professor diante da necessidade de formar sujeitos pensantes, críticos e autônomos. Quanto ao objeto de intervenção, decidiu-se por um recorte diante da amplitude do tema.

Published: March 2021

Este texto pretende apresentar uma resenha do livro intitulado Compreender e Ensinar - Por uma docência da melhor qualidade, da autora Terezinha Azerêdo Rios. O prefácio foi escrito por Selma Garrido Pimenta. Na introdução do livro, Rios procura fazer uma interlocução com todos aqueles que têm interesse na desafiadora tarefa de ser professor nesse mundo contemporâneo. Além disso, ela faz, uma articulação, entre a Filosofia e a Didática. Para tanto, ela divide seu livro em cinco capítulos. Rios descreve que seu livro tem o propósito de explorar conceitos sobre as competências do educador, bem como articular a investigação de fundamentos teórico-epistemológicos à vivência de situações concretas, retornando ao tema da competência articulada com a qualidade na educação, mas não a qualidade advinda da concepção neoliberal. O livro é de fácil e prazerosa leitura, e poderá contribuir para todos os profissionais que se interessam pelas questões educacionais, mais especificamente pelas práticas educativas que ocorrem no cotidiano das escolas.
Tempos distópicos: a crise estatal e democrática com a negligência do direito à diferença e do reconhecimento do refugiado
Authors: Seger Débora Patricia , Veronese Osmar
Published: March 2021

O artigo analisa a questão das migrações forçadas na pós-modernidade complexa, com ênfase nos refugiados, na crise estatal, na democracia e no renascimento de discursos distópicos ou retrotópicos. Objetiva-se, com base na teoria do reconhecimento e do direito à diferença, demonstrar que o atuar da sociedade, e até mesmo de Estados, dificulta o efetivo reconhecimento da diversidade, em especial quando contamos com um Estado em crise e um povo com bloqueios de canais de amor, alteridade e solidariedade, além de se verificar ressurgimentos de fundamentalismos, aniquiladores do direito à diferença. A percepção do futuro a partir de pessimismos e as constantes notícias de xenofobias e tratamentos desumanos para com os refugiados fazem necessário o questionamento do rumo que a humanidade esta tomando, pois ela sempre viveu e sempre viverá em mobilidade, inclusive em mobilidades forçadas, quando as circunstâncias de deixar o país tornam-se essenciais para a sobrevivência.
Memórias, história e uma aula de Matemática com crianças do Ensino Fundamental
Authors: Corrêa Bárbara Drielle Roncoletta , Scherer Suely
Published: March 2021

Neste artigo, estabelecemos alguns diálogos e reflexões em e a partir de uma narrativa sobre movimentos e conhecimentos mobilizados em uma aula de Matemática com uma turma dos Anos Iniciais do Ensino Fundamental. A narrativa foi constituída a partir de alguns resultados de uma pesquisa desenvolvida em uma escola pública de Educação Básica no Município de Campo Grande (MS) durante o período de dois anos. Na narrativa estabelecemos um diálogo com estudos de Mishra e Koehler (2006), que nos ajudaram a discutir sobre o Conhecimento Tecnológico, Pedagógico e do Conteúdo (CTPC), e com estudos de Sanchez (2002, 2003), que nos possibilitaram refletir sobre processos de Integração de Tecnologias Digitais ao Currículo. A partir da narrativa, em que dados da pesquisa são discutidos, foi possível refletir, entre outras problematizações, sobre relações entre o movimento de integração de tecnologias à aula de matemática e o conhecimento do tipo CTPC da professora.
Povoando a transitoriedade: refletindo Geografias a partir de relatos sobre o budismo tibetano no Brasil
Authors: Da Costa Machado Timmers Juliano
Published: March 2021

O presente artigo tem por objetivo fornecer subsídios para o desenvolvimento de uma análise geográfica sobre a dispersão do budismo tibetano da tradição Nyingma que chega ao sul do Brasil nos anos 1990 na cidade gaúcha de Três Coroas (RS). Metologicamente, o texto considera estudos de Geografia das Religiões de Zeny Rosendahl (1995) e em algumas idéias de Gomes (2012) e Haesbaert (2007) relações com o território. Quanto ao budismo, encontramos fontes nos escritos de Chagdud Tulku Rinpoche (2015) e em uma entrevista com o artista Alan Capetilla que conviveu com o mestre no Templo. Redes de relação global pautadas pela cultura religiosa e aspectos intrínsecos ao ideário e a prática religiosa budista têm influência na geografia que se materializa no templo Khadro Ling da cidade de Três Coroas (RS).
