Practices of Educational Volunteerism in History and Today
Authors: Бочко К.А. 
Published: October 2020

Статья посвящена анализу феномена педагогического волонтерства в историческом опыте и современном социокультурном контексте. Целью является изучение исторического развития практик и направлений педагогического волонтерства. Исследование обусловлено наличием трех противоречий, которые характерны для педагогического волонтерства: популярность и недостаточная изученность, большие возможности и отсутствие научно выверенных методов реализации, историческая преемственность и новизна. Основные методы исследования: теоретический и сопоставительный анализ, исторический метод, анализ публицистических материалов.
C опорой на теоретические исследования и практические материалы было отслежено историческое развитие педагогического волонтерства, раскрыты его отличительные особенности от других видов социальных практик. Эти особенности иллюстрируют три критерия: волонтерский, педагогический, институциональный. На основе критериев делается вывод, что первые волонтерские педагогические практики получили распространение в деятельности движения «Сетлемент» в США. В статье дан обзор пяти основных направлений педагогического волонтерства в отечественном и зарубежном опыте: наставничество, репетиторство, духовно-просветительское направление, образовательное волонтерство, социально-развивающая деятельность с детьми, оказавшимися в трудной жизненной ситуации. Также были уточнены
и обоснованы для использования понятия «педагогическое волонтерство», «волонтер-педагог».
The article analyzes the phenomenon of educational volunteerism against the historical background and in the modern socio-cultural context. The aim of the article is to analyze the evolution of various practices and trends of educational volunteerism. The research focuses on three contradictions characteristic of educational volunteering: popularity vs. insufficient investigation, great opportunities vs. lack of developed implementation methodology, deep historical roots vs. novelty. The article employs the following methods of research: theoretical and comparative analysis, historical method, analysis of publicistic materials. The analysis of theoretical research and practical materials enables the author of the article to trace the historical development of educational volunteerism, to investigate its peculiar features that make it different form other social practices. These peculiarities illustrate three criteria: volunteering, educational and institutional. Relying on the criteria, the author concludes that the first practices of educational volunteerism were employed by
the adherents of the Settlement movement in the USA. The article analyzes five major trends of pedagogical volunteerism in Russia and abroad: mentoring, guidance, tutorship, spiritual enlightenment, socio-educational support for children in difficult life situations. The article also substantiates such notions as educational volunteerism and teaching volunteers.
Factors Affecting Job Satisfaction in the Tourism Sector of Bangladesh
Authors: Parveen Rumana , Rahman Masud Ibn , Khaled Moslehuddin Chowdhury 
Published: October 2020

Purpose: The tourism sector is a very potential sector for Bangladesh in terms of growth and employment. Analyzing the literature, it can be observed that most of the researchers studied the tourist market and the degree of satisfaction of tourists. But job satisfaction as a human resource management concept, in the tourism sector has not been sufficiently investigated. Job satisfaction is particularly important in tourism sector as it is service oriented and people intensive. This study identified the antecedents of job satisfaction in tourism sector and their relative importance to the employees.
Methods: The study is quantitative in nature. A number of hypotheses were tested for relationships between job satisfaction and related facets like payment and benefits, advancement and growth, the work itself, leadership, communication, performance feedback and recognition, rewards, colleagues, and employee stress. Data were collected through a survey method and structured questionnaire from employees of different tourism-related businesses. With 81.8% response rate, a total of 409 error-free response sheets containing a total of 38 independent variables were considered for the analysis through Smart PLS 3.01 software. The hypotheses were tested by following the path coefficients of the factors where job satisfaction was the dependent variable. The model of the satisfaction of employees for Bangladesh was established by using the coefficients of relationship with all nine facets and job satisfaction.
Results: The standardized regression weights are shown with the nine factors Payment and Benefit (PB), Advancement and Growth (AG), Work Itself (WI), Work Itself (WI), Leadership (LE), Communication (COM), Performance feedback and Recognition (PFR), Rewards (RE), Colleague (COL) and Stress (STR). It was found that five factors (PB, AG, WI, LE, COM) are relatively more significantly responsible for job satisfaction or dissatisfaction, than other four factors (PFR, RE, COL, STR). It also found that the managerial and non-managerial employees show considerable differences in their job satisfaction across the organizations.
Implications: The results found in the study may act as a basis for future research in the HR issues of the tourism sector. The owners and managers of tourism companies should appreciate the necessity of employees being satisfied, because this will lead to greater commitment, loyalty, and quality service to the customers.
Originality: Due to the dominance of other factors like machines, materials, and other technologies, there is weak evidence in some cases whether there is always a positive and strong relationship between job satisfaction and firm performance. But in a human intensive service industry like tourism, job satisfaction of employees who are directly responsible for consumer experience, is bound to be a dominant factor. This paper is expected to be cited in that particular idea or context.

Abstract
Strong gravitational lenses are a rare and instructive type of astronomical object. Identification has long relied on serendipity, but different strategies—such as mixed spectroscopy of multiple galaxies along the line of sight, machine-learning algorithms, and citizen science—have been employed to identify these objects as new imaging surveys become available. We report on the comparison between spectroscopic, machine-learning, and citizen-science identification of galaxy–galaxy lens candidates from independently constructed lens catalogs in the common survey area of the equatorial fields of the Galaxy and Mass Assembly survey. In these, we have the opportunity to compare high completeness spectroscopic identifications against high-fidelity imaging from the Kilo Degree Survey used for both machine-learning and citizen-science lens searches. We find that the three methods—spectroscopy, machine learning, and citizen science—identify 47, 47, and 13 candidates, respectively, in the 180 square degrees surveyed. These identifications barely overlap, with only two identified by both citizen science and machine learning. We have traced this discrepancy to inherent differences in the selection functions of each of the three methods, either within their parent samples (i.e., citizen science focuses on low redshift) or inherent to the method (i.e., machine learning is limited by its training sample and prefers well-separated features, while spectroscopy requires sufficient flux from lensed features to lie within the fiber). These differences manifest as separate samples in estimated Einstein radius, lens stellar mass, and lens redshift. The combined sample implies a lens candidate sky density of ∼0.59 deg−2 and can inform the construction of a training set spanning a wider mass–redshift space. A combined approach and refinement of automated searches would result in a more complete sample of galaxy–galaxy lens candidates for future surveys.
Revisiting the Architecture of the KOI-89 System
Authors: Masuda Kento , Tamayo Daniel 
Published: October 2020

Abstract
While high stellar obliquities observed in exoplanetary systems may be attributed to processes that tilt the planetary orbits, it is also possible that they reflect misalignments between protoplanetary disks and stellar spins. This latter hypothesis predicts the presence of coplanar multiplanetary systems misaligned with their central stars. Here we reevaluate the evidence of such an architecture that has been claimed for the KOI-89 system. An early-type star, KOI-89 has one validated transiting planet, KOI-89.01/Kepler-462b (period 84.7 days, radius 3.0 R
⊕), and one transiting planet candidate, KOI-89.02 (period 207.6 days, radius 4.0 R
⊕), where the latter exhibits transit timing variations (TTVs). A previous modeling of the stellar gravity-darkening effect in the transit light curves inferred a high stellar obliquity of ≈70°. We perform photodynamical modeling of the Kepler transit light curves and use the resulting constraints on the orbital configuration and transit times to update the gravity-darkened transit model. As a result, we find no firm evidence for the gravity-darkening effect in the transit shapes and conclude that stellar obliquity is not constrained by the data. Given the evidence for low orbital eccentricities from the dynamical analysis, the system architecture can thus be consistent with many other multitransiting systems with flat, near-circular orbits aligned with the stellar spin. We find that the TTVs imparted on its neighbor imply that KOI-89.01 has a mass ≳20 M
⊕. This would render it one of the densest known sub-Neptunes, mostly composed of a solid core. Lower masses are possible if the TTVs are instead due to an unseen third planet.
High-resolution Spectra of Earth-like Planets Orbiting Red Giant Host Stars
Authors: Kozakis Thea , Kaltenegger Lisa 
Published: October 2020

Abstract
In the near future we will have ground- and space-based telescopes that are designed to observe and characterize Earth-like planets. While attention is focused on exoplanets orbiting main-sequence stars, more than 150 exoplanets have already been detected orbiting red giants, opening the intriguing question of what rocky worlds orbiting in the habitable zone (HZ) of red giants would be like and how to characterize them. We present a high-resolution spectral database of reflection and emission spectra for nominal Earth-like planets orbiting in the red giant HZ from the visible to infrared (0.4–20 μm) for planets orbiting at the Earth-equivalent distance. We also show the change of such planetary spectra through the evolution of their red giant hosts. While the luminosity of the host increases the contrast ratio between star and planet, the increased orbital distance of the HZ for red giant hosts relaxes the light suppression requirements close to the star, which could make such planets interesting targets to characterize and search for signs of life, if new coronagraph designs with higher suppression at larger orbital separations could be developed. We assess the feasibility of characterizing atmospheric features including biosignatures for such planets with the proposed mission concept Large UV/Optical/IR Surveyor (LUVOIR).
Gamma-Ray and Radio Background Constraints on Cosmic Rays in Milky Way Circumgalactic Medium
Authors: Jana Ranita , Roy Manami , Nath Biman B. 
Published: October 2020

Abstract
We study the interaction of cosmic rays (CRs) with the diffuse circumgalactic gas of the Milky Way (MW) galaxy that results in hadronic γ-ray emission and radio synchrotron emission. We aim to constrain the CR population in our circumgalactic medium (CGM) with the help of the observed isotropic γ-ray background (IGRB), its anisotropy, and radio continuum. We modify different models of CGM gas in hydrostatic equilibrium discussed in the literature by including a cosmic-ray population, parameterized by η ≡ P
CR/P
th. For the simplest isothermal model, while the IGRB intensity allows η ≲ 3, the anisotropy resulting from the solar system’s off-center position in MW rules out all values of η. For the precipitation model, in which the cooling of the CGM gas is regulated with an optimum ratio of cooling time to freefall time, while the observed IGRB intensity allows η ≲ 230, the observed anisotropy allows only very large values of η, of order ≳100. The radio continuum limits η ≲ 400 for the precipitation model and does not constrain the isothermal model; however, these constraints are mitigated by synchrotron loss time being comparable to CR diffusion timescales. These bounds are relevant for current numerical simulations that indicate a significant CR population in CGM of galaxies of MW mass.
« S’entendre et s’écouter ». Les femmes speakerines dans les émissions françaises de la BBC, 1940-1941
Authors: Lévy Clémence 
Published: October 2020

L’entre-deux-guerres et le second conflit mondial sont moteurs du développement de la radio acquérant une place essentielle au niveau social et gouvernemental. Celle-ci permet une influence et une maîtrise des esprits, une diffusion de l’information, mais surtout le maintien du lien entre territoires dont les relations diplomatiques et humaines sont coupées. L’Appel du 18 juin 1940 est l’initiateur d’une maîtrise britannique des ondes radiophoniques par le biais de la BBC, avec la mise en place d’émissions de radio féminines en français. Il permet d’endiguer les premiers moteurs d’émancipation féminine durant le conflit, dans une dynamique speakerines -médias, où la place des femmes est centrale dans les sujets abordés et dans la diffusion médiatique de ces émissions.
De la Phalange à la résistance antifranquiste : la théâtralisation de la figure de Dionisio Ridruejo chez Ignacio Amestoy
Authors: Dutoya Claire 
Published: October 2020

Dionisio Ridruejo, una pasión española, pièce de théâtre écrite en 1982 par Ignacio Amestoy, théâtralise la figure historique et politique de Dionisio Ridruejo grâce au dédoublement identitaire du personnage du Colonel Arenas. Ce processus dramatique permet de faire affleurer de façon tragique la nécessité de la résistance au franquisme chez le Colonel Arenas. Entre derniers regains de violence phalangiste et sursauts critiques, le Colonel Arenas reconnaît en Ridruejo son double. L’étude du mécanisme du dédoublement permet de mettre en lumière l’importance du cheminement qui mène à la résistance, véritable itinéraire tragique et chemin de croix idéologique. Le recours au théâtre documentaire donne au discours du héros une place prépondérante et permet de condenser l’itinéraire idéologique de Ridruejo. Au-delà de la théâtralisation de la figure de Ridruejo, Amestoy représente la tragédie collective de la Guerre civile et du franquisme en questionnant l’attribution d’étiquettes idéologiques immuables pour caractériser les parcours vitaux individuels et collectifs durant cette période. Dionisio Ridruejo, una pasión española n’a été représentée qu’en 2014, soit plus de trente ans après son écriture : le récent montage de la pièce au Centre Dramatique National (Madrid) pourrait être interprété comme un engagement artistique de l’auteur et du metteur en scène afin de constituer le point de départ d’une réflexion sur l’Histoire récente de l’Espagne.
Octavio Paz et Cornelius Castoriadis : résister à la corruption du langage
Authors: Leylavergne Laurent 
Published: October 2020

Mon propos est consacré à la question de la résistance à la corruption du langage au XXe siècle à travers les œuvres et les parcours du poète Octavio Paz et du philosophe Cornelius Castoriadis, liés par une estime réciproque et des préoccupations communes, dissidents inclassables contre les langues totalitaires ou la marchandisation des mots et des idées. Cela me conduit à une réflexion conjointe sur la nature du langage et la création poétique.
Marginália, résister aux limites de l’art dans le Brésil des années 60-70
Authors: Lespes Muñoz Elena 
Published: October 2020

Au Brésil, le coup d’État du 31 mars 1964, mené par le maréchal Castelo Branco, marque l’avènement de la dictature militaire (1964-1985). Dans le contexte de censure et de répression qui s’en suit, les artistes sont amenés à élaborer des stratégies de contournement, tant dans les pratiques artistiques en elles-mêmes que dans les circuits et les espaces où elles s’expriment. En privilégiant des formes dites « performatives » et en contournant la matérialité de l’art, ces artistes mettent en cause le système de l’art (son objet, comme ses espaces). En étant là où on ne l’attend pas et dans des formes qui lui étaient jusqu’alors étrangères, l’art brésilien de cette période est un art en résistance, car il se joue des limites de sa propre définition et des espaces de libertés restreintes qui lui sont octroyés. Cet article vise à présenter les enjeux de ces déplacements, aussi bien physiques qu’épistémologiques, au travers du travail de certains artistes de cette période (Cildo Meireles, Artur Barrio, Antônio Manuel, etc.)

ACTIVIN RECEPTOR LIGAND FOR THR TREATMENT OF BETA-THALASSEMIA: a SERENDIPITOUS DISCOVERY
Authors: Motta Irene , Brancaleoni Valentina , Nava Isabella , Delbini Paola , Duca Lorena 
Published: October 2020

b-thalassemia is a hereditary disorder caused by defective production of b-globin chains of hemoglobin (Hb) that leads to an increased a/b globins ratio with subsequent free a-globins. Alpha globin excess causes oxidative stress, RBCs membrane damage, premature death of late-stage erythroid precursors, resulting in ineffective erythropoiesis.
The transforming growth factor b (TGF-b) superfamily signaling acts on biological processes, such as cell quiescence, apoptosis, proliferation, differentiation, and migration, and also plays an important role in the regulation of hematopoiesis. This pathway can lose its physiologic regulation in pathologic conditions, leading to anemia and ineffective erythropoiesis. Activin receptor ligand trap molecules such as Sotatercept and Luspatercept downregulate the TGF-b pathway by inhibiting the Smad2/3 cascade, thus alleviating anemia in patients with b-thalassemia and myelodysplastic syndromes.
In this review, we describe in extenso the TGF-b pathway, as well as the molecular and biological basis of activin receptors ligand traps, focusing on their role in various b-thalassemia experimental models. The most recent results from clinical trials on sotatercept and luspatercept will also be reviewed.
ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR ACUTE MYELOID LEUKEMIA OF THE ELDERLY: REVIEW OF THE LITERATURE AND PERSPECTIVES.
Authors: Magliano Gabriele , Bacigalupo Andrea 
Published: October 2020

Acute myeloid leukemia (AML) in adults older than 60 years old has a poor prognosis. Elderly patients often present with comorbidities and an adverse biology of the disease, with higher genetic risk and chemoresistance. Allogeneic hematopoietic stem cell transplantation (HSCT) can be an effective treatment, and can improve overall survival (OS).Intensive chemotherapy (IC) before HSCT and myeloablative conditioning regimens can produce significant toxicity and transplant-related mortality (TRM). Reduced-intensity conditioning (RIC) or non-myeloablative (NMA) regimens appear to preserve the graft-versus-leukemia effect, and may improve survival. The increasing knowledge in AML of the elderly is currently being associated with a multidimensional approach to identify those patients eligible for targeted therapy, such as Flt3 inhibitors, and/or allogeneic HSCT.
