Published: June 2023

У статті на основі теоретичного аналізу та узагальнення розкрито поняттєво-термінологічні аспекти педагогічної біографіки як предмета наукових досліджень.
В сучасному науково-інформаційному просторі, в умовах накопичення біографічної інформації, розвитку теоретичних та методичних засад біографічних досліджень щодо особливостей застосування дослідницького інструментарію, понятійного апарату, науково-видавничої роботи у цьому напрямі актуальним є вивчення питань педагогічної біографіки.
Педагогічна біографіка – важливе науково-методологічне підґрунтя наукових біографічних досліджень в епоху стрімкого накопичення інформації. Питання розробки поняттєвого апарату в педагогічних дослідженнях, як і в будь-яких інших, набувають особливого значення для їхньої методологічної оснащеності. У зв’язку з цим постає потреба вивчення, систематизації та узагальнення різних дослідницьких підходів до розробки поняттєвого апарату в цілому та педагогічної біографіки зокрема.
З’ясовано, що в умовах розвитку теоретичних та методичних засад біографічних наукових досліджень актуальним є вивчення питань педагогічної біографіки як сфери наукової творчості, видавничо-інформаційної роботи, біографічних досліджень діяльності педагогів, освітян, громадських діячів на певному історико-педагогічному етапі.
ЛИСТ ЯК ФОРМА ЗВЕРТАННЯ ДО ЧИТАЧА В ПЕДАГОГІЧНИХ ПРАЦЯХ В. СУХОМЛИНСЬКОГО
Authors: Сухомлинська Леся 
Published: June 2023

У статті здійснено теоретичний аналіз малорозробленого аспекту педагогічної спадщини Василя Сухомлинського – епістоляріїв як своєрідного прийому звертання до читача, в яких порушено широке коло питань.
Охарактеризовано епістолярну форму звертання до читача у педагогічних працях В. Сухомлинського як різновид мікроісторичного підходу, що сконцентрований на особистісній інтерпретації проблематики і суттєво збагачує розуміння виховної системи педагога. Виявлено, що його адресатами виступали посадовці, вчителі, колеги-однодумці, опоненти, батьки, діти та ін. Встановлено, що метою використання епістолярного прийому при написанні педагогічних праць було прагнення постійного діалогу з читачем з метою отримання відгуку та для підсилення емоційного виховного впливу. З’ясовано, що вищезгаданий прийом став надзвичайно дієвим інструментом транслювання В. Сухомлинським нових ідей і поглядів на освіту та виховання. Виокремлено педагогічні праці, що найбільш яскраво репрезентують лист як форму звертання до читача, насамперед у таких творах, як «Листи до сина», «Листи до доньки», «Лист про педагогічну етику» тощо.
Зроблено висновок про важливість таких дослідницьких підходів, які надають можливість всебічно проаналізувати педагогічні ідеї, досвід та власне особистість самого Василя Сухомлинського.
З’ясовано, що епістолярна спадщина педагога є невід’ємним складником його творчості, містить у собі багато оригінальних і цінних ідей, але досі залишається недостатньо вивченою, малодослідженою і потребує подальшого розгляду та аналізу.

Introduction: Blastocystis sp. is an intestinal protozoan that is commonly reported, but whose clinical significance remains controversial. Clinical forms of this infection range from asymptomatic carriage to clinical signs, specifically gastrointestinal ones. There is a lack of data on the epidemiology of this protist in Gabon. This study was carried out to provide data on the frequency of Blastocystis sp. infection and its association with clinical signs and the haemoglobin rate. Methods: A cross-sectional study was conducted between September 2018 and November 2019. Stool samples were collected in five of the nine provinces of Gabon from children and adults. Sociodemographic and clinical data were recorded using a standardised pre-tested questionnaire. Haematological parameters and temperature were reported in a laboratory register. Parasitological diagnosis was performed using stool direct examination and a Merthiolate-Iodine-Formaldehyde (M.I.F) concentration to detect Blastocystis sp. Results: In total, 843 participants were interviewed and examined; 414 brought back stool samples. The frequency of Blastocystis sp. infection was 45.2% (n = 187/414), and it increased with age: from 20.0% in young children to 49.5% in adults (P = 0.0057). Being a male (P = 0.08) tended to be associated with Blastocystis sp. carriage. In the multivariate logistic regression, only males were associated with Blastocystis sp. infection and had a 4.3-fold higher risk of being infected than females did (adjusted odds ratio = 4.3; 95% CI = 1.2–15.6; P = 0.03). Diarrhoea, abdominal pain and colitis were observed in some patients with Blastocystis sp. monoinfection. No relation between Blastocystis sp. carriage and anaemia was found. Conclusion: The frequency of Blastocystis sp. infection was high. Males were more at risk of being infected. Blastocystis sp. could be used as indicator in the improvement of environmental sanitation and hygiene, coupled with improved housing. Additional investigations in a population with clinical symptoms should be performed.

Illustrations of interactions needed when investigating sleep using a type of AM-PM PM-AM design

Published: June 2023

AbstractSleep has long been thought of and promoted to be beneficial for memory. Some claims that sleep aids memory have been made in the absence of a critical interaction. This condition is necessary when using a commonly-used experimental design (a type of AM-PM PM-AM design). We propose that a sleep effect exists only if there is an interaction between groups (experimental and time-of-day controls) and the time of test or study (morning and evening). We show different patterns of results that would and would not support a sleep effect with empirical and model-generated data from recognition memory experiments and hypothetical data. While we use these data to make our point, our suggestions apply to any memory and non-memory-related investigation (e.g., emotional memory, false memory susceptibility, language learning, problem-solving). Testing for and finding the proper interaction will add to the evidence that sleep boosts performance.
Active Stars in the Spectroscopic Survey of Mid-to-late M Dwarfs within 15 pc

Published: June 2023

Abstract
We present results from the volume-complete spectroscopic survey of 0.1–0.3 M
⊙ M dwarfs within 15 pc. This work discusses the active sample without close binary companions, providing a comprehensive picture of these 123 stars with Hα emission stronger than −1 Å. Our analysis includes rotation periods (including 31 new measurements), Hα equivalent widths, rotational broadening, inclinations, and radial velocities, determined using high-resolution, multiepoch spectroscopic data from the TRES and CHIRON spectrographs supplemented by photometry from TESS and MEarth. Using this volume-complete sample, we establish that the majority of active, low-mass M dwarfs are very rapid rotators: specifically, 74% ± 4% have rotation periods shorter than 2 days, while 19% ± 4% have intermediate rotation periods of 2–20 days, and the remaining 8% ± 3% have periods longer than 20 days. Among the latter group, we identify a population of stars with very high Hα emission, which we suggest is indicative of dramatic spindown as these stars transition from the rapidly rotating mode to the slowly rotating one. We are unable to determine rotation periods for six stars and suggest that some of the stars without measured rotation periods may be viewed pole-on, as such stars are absent from the distribution of inclinations we measure; this lack notwithstanding, we recover the expected isotropic distribution of spin axes. Our spectroscopic and photometric data sets also allow us to investigate activity-induced radial-velocity variability, which we show can be estimated as the product of rotational broadening and the photometric amplitude of spot modulation.

Abstract
While radial velocity surveys have demonstrated that the population of gas giants peaks around 3 au, the most recent high-contrast imaging surveys have only been sensitive to planets beyond ∼10 au. Sensitivity at small angular separations from stars is currently limited by the variability of the point-spread function. We demonstrate how moderate-resolution integral-field spectrographs can detect planets at smaller separations (≲ 0.3“) by detecting the distinct spectral signature of planets compared to the host star. Using OSIRIS (R ≈ 4000) at the W.M. Keck Observatory, we present the results of a planet search via this methodology around 20 young targets in the Ophiuchus and Taurus star-forming regions. We show that OSIRIS can outperform high-contrast coronagraphic instruments equipped with extreme adaptive optics and non-redundant masking in the 0.05“–0.3“ regime. As a proof of concept, we present the 34σ detection of a high-contrast M dwarf companion at ≈0.1“ with flux ratio of ≈ 0.92% around the field F2 star HD 148352. We developed an open-source Python package, breads, for the analysis of moderate-resolution integral-field spectroscopy data in which the planet and the host star signal are jointly modeled. The diffracted starlight continuum is forward-modeled using a spline model, which removes the need for prior high-pass filtering or continuum normalization. The code allows for analytic marginalization of linear hyperparameters, which simplifies the posterior sampling of other parameters (e.g., radial velocity, effective temperature). This technique could prove very powerful when applied to integral-field spectrographs such as NIRSpec on the JWST and other upcoming first-light instruments on the future Extremely Large Telescopes.
X-Ray Flares in the Long-term Light Curve of Low-luminosity Active Galactic Nucleus M81*
Authors: Tomar Gunjan , Gupta Nayantara 
Published: June 2023

Abstract
Most active galactic nuclei at the center of the nearby galaxies have supermassive black holes accreting at sub-Eddington rates through hot accretion flows or radiatively inefficient accretion flows, which efficiently produce jets. The association of radio and X-ray flares with the knot ejection from M81* inspires us to model its multiwavelength spectral energy distribution (SED) during these flares to constrain the physical parameters of the jet. Moreover, we construct a long-term light curve in X-rays to identify the flares in the available data and constrain the jet parameters during those periods. The jet activity may vary on short as well as long timescales, which may produce flares in different frequency bands. The SEDs from radio to X-ray during the quiescent as well as flaring states are found to be satisfactorily explained by synchrotron emission of relativistic electrons from a single zone. The variation in the values of the jet parameters during the different states is shown and compared with high-synchrotron peaked blazars.
Electrostatic Solitary Waves in the Venusian Ionosphere Pervaded by the Solar Wind: A Theoretical Perspective
Authors: Rubia R. , Singh S. V. , Lakhina G. S. , Devanandhan S. , Dhanya M. B. , Kamalam T. 
Published: June 2023

Abstract
Electrostatic solitary waves (ESWs) in the Venusian ionosphere that are impinged by the solar wind are investigated using a homogeneous, collisionless, and magnetized multicomponent plasma consisting of Venusian H+ and O+ ions, Maxwellian Venusian electrons and streaming solar wind protons, and suprathermal electrons following κ − distribution. The model supports the propagation of positive potential slow O+ and H+ ion-acoustic solitons. The evolution and properties of the solitons occurring in two sectors, viz., dawn-dusk and noon-midnight sector of the Venus ionosphere at an altitude of (200–2000) km, are studied. The theoretical model predicts positive potential solitons with amplitude ∼(0.067–56) mV, width ∼(1.7–53.21) m, and velocity ∼(1.48–8.33) km s−1. The bipolar soliton electric field has amplitude ∼(0.03–27.67) mV m−1 with time duration ∼(0.34–22) ms. These bipolar electric field pulses when Fourier transformed to the frequency domain occur as a broadband electrostatic noise, with frequency varying in the range of ∼9.78 Hz–8.77 kHz. Our results can explain the observed electrostatic waves in the frequency range of 100 Hz–5.4 kHz in the Venus ionosphere by the Pioneer Venus Orbiter mission. The model can also be relevant in explaining the recent observation of ESWs in the Venus magnetosheath by the Solar Orbiter during its first gravity assist maneuver of Venus.

ObjectiveTo evaluate the safety and efficacy of tocilizumab (TCZ) in giant cell arteritis (GCA) in a large North American cohort.MethodsPatients with GCA treated with TCZ between January 1, 2010, and May 15, 2020, were retrospectively identified. Kaplan-Meier methods were used to estimate time to TCZ discontinuation and time to first relapse after TCZ discontinuation. Poisson regression models were used to compare annualized relapse rates before, during, and after TCZ use. Age- and sex-adjusted risk factors associated with relapse on and off TCZ and development of adverse events of significant interest (AESIs) were examined using Cox models.ResultsOne hundred fourteen patients (60.5% female) were included with mean (SD) age 70.4 (8.2) years. Median duration from GCA diagnosis to TCZ start was 4.5 months. Median overall duration of TCZ treatment was 2.3 years. Relapse rate prior to TCZ start (0.84 relapses/person-year) was 3-fold reduced while on TCZ (0.28 relapses/person-year;P< 0.001) but increased to 0.64 relapses/person-year after TCZ discontinuation. Fifty-two patients stopped TCZ after a median of 16.8 months; 27 relapsed after discontinuation (median: 8.4 months; 58% relapsed within 12 months). Only 14.9% of patients stopped TCZ because of AESIs. Neither dose/route of TCZ, presence of large-vessel vasculitis, nor duration of TCZ therapy prior to discontinuation predicted relapse after TCZ stop.ConclusionTCZ is well tolerated in GCA, with low rates of discontinuation for AESIs. However, relapse occurred in > 50% despite median treatment > 12 months. Since the duration of TCZ prior to discontinuation did not significantly affect subsequent risk of GCA recurrence, further research is needed to determine the optimal duration of therapy.
La Russie de Poutine : une raison d’État sans État
Authors: Tenzer Nicolas 
Published: June 2023

Les premiers Irlandais aimaient les jeux de société. Cela ressort clairement du matériel de jeu découvert et des nombreuses références aux jeux de société dans la littérature vernaculaire. Bien qu’une grande partie de la littérature séculaire présente des récits se déroulant dans un passé imaginaire, les textes peuvent néanmoins être étudiés pour donner un aperçu des attitudes à l’égard du jeu, tant pour les hommes que pour les femmes. Avant les échecs, le jeu le plus important était le fidchell local, un jeu de stratégie pure dérivé du ludus latrunculorum romain. Une sélection de références au fidchell dans la prose et la poésie, principalement de l’ancien et du moyen irlandais ( vii e - xiii e s.), permet d’explorer le rôle des femmes en tant que joueuses entre elles et contre les hommes, en se concentrant sur les thèmes suivants : le statut, le contexte social et physique des jeux, la matérialité des équipements de jeu des femmes, la relation entre jeux et alcool, le jeu, l’érotisme et son absence, et les attitudes envers les compétences intellectuelles féminines.
Les médiatisations de l’« affaire de la Ligue du LOL ».
Authors: Raymond Lucie , Verquere Laura 
Published: June 2023

Cette contribution revient sur l’affaire médiatique de la « Ligue du LOL » qui, en février 2019, a révélé des actes de (cyber)harcèlement, commis par des journalistes et des communicants, principalement à l’encontre de jeunes femmes féministes appartenant au même milieu professionnel. Dans le cadre de ce dossier, nous proposons de prendre de la hauteur par rapport à la controverse médiatique qui a mis en opposition deux types de discours sur le modèle binaire de l’accusation, d’une part, et de la réparation d’image, d’autre part. Nous interrogeons ainsi la manière dont la médiatisation de l’affaire produit des savoirs sur le cyberharcèlement tout en reconduisant des formes d’ignorance en lien avec le maintien de rapports de domination structurels.

Abstract

Introduction:
There is no bedside clinical examination-based prediction score for Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in children with neuromuscular diseases (NMDs) presenting with proximal limb-girdle weakness.

Methods:
We compared the details of 200 cases of lower motor neuron type of weakness and had some proximal limb-girdle muscle weakness and divided them into 2 groups: with/without a confirmed diagnosis of DMD/BMD. We determined the predictive factors associated with a diagnosis of DMD/BMD using multivariate binary logistic regression. We assessed our proposed prognostic model using both discrimination and calibration and subsequently used the bootstrap method to successfully validate the model internally.

Results:
A total of 121 patients had DMD/BMD and the rest of the patients had other diagnoses. Male gender, presence of Gower’s sign, valley sign, toe walking, calf pseudohypertrophy, and tongue hypertrophy were independent predictors for a confirmed diagnosis of DMD/BMD and included in the final CVT2MG score (Calf pseudohypertrophy, Valley sign, Toe walking, Tongue hypertrophy, Male gender, and Gower’s sign). The final model showed good discrimination (AUC = 87.4% [95% CI: 80.5–92.3%, P < 0.001]) and calibration (P = 0.57). A score of 6 or above appeared to be the best cutoff for discriminating between the DMD/BMD group and the rest of the group with both sensitivity and specificity of 98%. The interrater reliability was almost perfect between two pediatric neurologists and strong between a pediatric neurologist and a pediatric neurology trainee resident (k = 0.91 and 0.87).

Conclusion:
The CVT2MG score has good sensitivity and specificity in predicting a confirmed diagnosis of DMD/BMD in subsequent tests.
