Authors: Škorić Dušan Đ , Klisurić Olivera R , Jakimov Dimitar S , Sakač Marija N , Csanádi János J
Published: October 2021

A practical and high-yielding Schmidt reaction for the synthesis of fused tetrazoles from bile acid precursors was developed. Mild reaction conditions using TMSN3 instead of hydrazoic acid as an azide source produced good yields of the desired tetrazoles. These conditions could be applied to other steroidal precursors. Additionally, an improved methodology for the synthesis of different ketone and enone precursors from cholic acid, deoxycholic acid, and chenodeoxycholic acid was established. Newly obtained tetrazole derivatives were characterized by NMR and X-ray diffraction spectroscopy. In a number of cases, preliminary antiproliferative tests of new compounds showed strong and selective activity towards certain tumor cell lines.
The Modern State and the Dynamics of Minor Landforms Found in the Steppes of the Southern-Minusinsk Hollow
Authors: Тюменцева Е.М.
Published: October 2021

В статье изложены результаты многолетних исследований генезиса, морфологии, особенностей функционирования, современного состояния и динамики малых эрозионных форм рельефа в условиях котловин гор Южной Сибири на примере Южно-Минусинской котловины. Овражные формы представлены здесь локально. Доминируют береговые промоины и овраги, секущие крутые борта долин рек Абакан, Енисей и их притоков. Густота расчленения и плотность современных овражных форм рельефа возрастает на сельскохозяйственных землях (пашни и пастбища) и в пределах селитебных ландшафтов. Размеры малых эрозионных форм рельефа отличаются большим диапазоном. Так, протяженность коротких промоин составляет первые десятки метров, длинных логов — 3–5 км. Глубина вреза изменяется от 1,5–3 м до 10–20 м, ширина между бровками достигает 40–60 м. В настоящее время, несмотря на период увеличения увлажненности территории, после достаточно длительного засушливого периода овражные формы активно задерновываются. Этому способствует рост температуры и выпадение осадков слабой интенсивности.
В результате происходит зарастание нарушенных земель ильмом мелколистным, наблюдается превращение степных ландшафтов в парковые.

The article discusses the results of a multiannual research of the genesis, morphology, modern state and dynamics of minor landforms that can be found in the mountains of Southern Siberia in the Southern-Minusinsk Hollow. The majority of ravine landforms found in the area are bank gullies infesting the steep banks of the Abakan River, the Yenisei River and their tributaries. The density of ravine dismemberment increases in agricultural areas (arable lands and pastures) and in residential areas. The size of ravine landforms varies over a wide range. The length of short gullies does not exceed a few dozen meters. The length of long logs can reach 3–5 kilometres. The depth of incision varies from 1.5–3 metres to 10–20 metres. The distance between the brows of a ravine can reach 40–60 meters.
Nowadays, despite a period of higher humidity, prolonged dry periods and high temperatures make ravines peaty. As a result, the areas overgrow with small-leaved elm and steppe landscapes are gradually transformed into parks.

We present an analysis of both Transiting Exoplanet Survey Satellite (TESS) and Zwicky Transient Facility (ZTF) observations of the eclipsing cataclysmic variable IPHAS J051814.34+294113.2 (IPHAS J0518). The TESS light curve shows numerous eclipses superimposed on two outbursts, and ZTF data show frequently outbursts recurring on average every 20.7 days and 12.9 days for long and short outbursts, respectively. This makes IPHAS J0518 to be identified as a possible Z Cam-type dwarf nova. Its quiescent magnitude is ∼16.7 in the g band. The orbital period is determined to be 4.95 hr. By combining the observed orbital period with the semiempirical relations of Knigge et al., we estimate the donor mass as M
2 = 0.48M
⊙. The eclipse phase measurements are used to constrain the binary parameters. The orbital inclination is limited in the range of 75.°3 ≤ i < 81.°7, and the mass ratio is derived as 0.33 < q ≤ 0.73. Furthermore, we analysis the accretion disk eclipse and find that the total disk eclipse is possible during quiescence, whereas during outburst the disk would be only partially obscured. This indicates that the disk will become larger as the outburst proceeds. We also study the changes of the eclipse depth against the out-of-eclipse flux in IPHAS J0518. The results show evidence of the expansion in the disk size and the variations in the radial-temperature gradient during outburst.
The Stellar Initial Mass Function and Population Properties of M89 from Optical and NIR Spectroscopy: Addressing Biases in Spectral Index Analysis*
Authors: Lonoce I. , Feldmeier-Krause A. , Freedman Wendy L.
Published: October 2021

The complexity of constraining the stellar initial mass function (IMF) in early-type galaxies cannot be overstated, given the necessity of very high signal-to-noise ratio (S/N) data and the difficulty of breaking the strong degeneracies that occur among several stellar population parameters, including age, metallicity, and elemental abundances. With this paper, the second in a series, we present a detailed analysis of the biases that can occur when retrieving the IMF shape by exploiting both optical and near-IR IMF-sensitive spectral indices. As a test case, here we analyze data for the nearby galaxy M89, for which we have high-S/N spectroscopic data that cover the 3500–9000 Å spectral region and allow us to study the radial variation of the stellar population properties out to 1R

e
. Carrying out parallel simulations that mimic the retrieval of all of the explored stellar parameters from a known input model, we quantify the amount of bias at each step of our analysis. From more general simulations, we conclude that to accurately retrieve the IMF, it is necessary to retrieve accurate estimates not only of the age and metallicity but also of all of the elemental abundances that the spectral index fits are sensitive to. With our analysis technique applied to M89, we find consistency with a bottom-heavy IMF with a negative gradient from the center to half R

when using the Conroy et al. and Vazdekis et al. EMILES stellar population models. We find agreement with both a parallel full spectral fitting of the same data and literature results.
Very Large Telescope Spectroscopy of Ultra-faint Dwarf Galaxies. I. Boötes I, Leo IV, and Leo V

Published: October 2021

We perform consistent reductions and measurements for three ultra-faint dwarf galaxies (UFDs): Boötes I, Leo IV, and Leo V. Using the public archival data from the GIRAFFE spectrograph on the Very Large Telescope (VLT), we locate new members and provide refined measurements of physical parameters for these dwarf galaxies. We identify nine new Leo IV members and four new Leo V members, and perform a comparative analysis of previously discovered members. Additionally, we identify one new binary star in both Leo IV and Leo V. After removing binary stars, we recalculate the velocity dispersions of Boötes I and Leo IV to be

km s−1, respectively; we do not resolve the Leo V velocity dispersion. We identify a weak velocity gradient in Leo V that is ∼4× smaller than the previously calculated gradient and that has a corresponding position angle that differs from the value in the literature by ∼120°. Combining the VLT data with previous values from the literature, we reanalyze the Boötes I metallicity distribution function and find that a model including infall of pristine gas, while Boötes I was forming stars’ best fits the data. Our analysis of Leo IV, Leo V, and other UFDs will enhance our understanding of these enigmatic stellar populations and contribute to future dark matter studies. This is the first in a series of papers examining 13 UDFs observed with VLT/GIRAFFE between 2009 and 2017. Similar analyses of the remaining 10 UFDs will be presented in forthcoming papers.
DirtyGrid II: An Analysis of the Dust and Stellar Properties in Nearby Star-forming Galaxies
Authors: Law Ka-Hei , Gordon Karl D. , Misselt Karl A.
Published: October 2021

We study the dust and stellar properties of the Spitzer Infrared Nearby Galaxies Survey galaxies by fitting the ultraviolet (UV) to far-infrared (FIR) spectral energy distributions using the DirtyGrid stellar and dust radiative transfer models. We find a minimum of two components of different stellar ages are needed, representing a young and an old stellar population, in order to obtain good fits for most of the galaxies. Our total dust masses agree with literature dust masses to within a factor of 2, and the residuals correlate most strongly with the stellar mass surface density of the old component. The LMC-2 dust grain model best describes the dust found in these normal star-forming galaxies. The derived attenuation curves are steeper than those found previously for starburst galaxies, and possess a weak 2175 Å feature. The relative contribution of the young and old stellar components as a function of wavelength reveals that the young component dominates the far-UV and MIPS24 bands, the old component dominates the optical/near-IR bands, and both components are important for the FIR bands. The DirtyGrid star formation rates (SFRs) are consistent with a number of literature SFR indicators within a factor of 2. The differences we find are primarily due to the influence of the old stellar population that are accounted for by the DirtyGrid SFRs fitting on a galaxy-by-galaxy basis using the information present in the full UV-FIR spectral energy distribution.

We present photometric and spectroscopic observations of the 03fg-like Type Ia supernova (SN Ia) ASASSN-15hy from the ultraviolet (UV) to the near-infrared (NIR). ASASSN-15hy shares many of the hallmark characteristics of 03fg-like SNe Ia, previously referred to as “super-Chandrasekhar” SNe Ia. It is bright in the UV and NIR, lacks a clear i-band secondary maximum, shows a strong and persistent C ii feature, and has a low Si ii
λ6355 velocity. However, some of its properties are also extreme among the subgroup. ASASSN-15hy is underluminous (M

ASASSN-15hy lacks the prominent H-band break emission feature that is typically present during the first month past maximum in normal SNe Ia. Such events may be a potential problem for high-redshift SN Ia cosmology. ASASSN-15hy may be explained in the context of an explosion of a degenerate core inside a nondegenerate envelope. The explosion impacting the nondegenerate envelope with a large mass provides additional luminosity and low ejecta velocities. An initial deflagration burning phase is critical in reproducing the low 56Ni mass and luminosity, while the large core mass is essential in providing the large diffusion timescales required to produce the broad light curves. The model consists of a rapidly rotating 1.47 M
⊙ degenerate core and a 0.8 M
⊙ nondegenerate envelope. This “deflagration core-degenerate” scenario may result from the merger between a white dwarf and the degenerate core of an asymptotic giant branch star.
Estimating the Mean Free Paths of Energetic Protons Using Differential Intensity Spectra
Authors: Li Gen , Bruno Alessandro , Lugaz Noé
Published: October 2021

An analytical calculation is presented to derive the mean free paths of energetic protons in large western solar energetic particle (SEP) events during the first 12 hr after the event onset utilizing the differential spectra averaged over successive time intervals of 3 hr. The model assumes diffusive transport of energetic particles in a radial magnetic flux tube and neglects solar wind convection and adiabatic cooling. The model further assumes that particles over the considered energies (>10 MeV) are injected instantaneously near the Sun. Using the model, we reproduce the differential spectra averaged over successive time intervals after event onset and derive the radial mean free paths (λ
mfp) for protons at the energies where the two spectra over successive time intervals intersect. We then select eight western SEP events during the past solar cycle and apply the scheme. The derived λ
mfp ranges from 0.016 to 0.149 au. Our method finds smaller mean free paths than the lower limit of the “Palmer consensus” (0.04 au) in approximately 35% of the cases. We also combine differential intensity spectra and fluence to estimate the number of crossings (N
c) of particles passing through 1 au at applicable energies. The average N
c, excluding a twin-CME event, is 17.7, which indicates that diffusive transport of SEPs is capable of elevating the fluence observed at 1 au by one order of magnitude compared to if particles stream through 1 au nearly scatter-free.

The core mass of galaxy clusters is both an important anchor of the radial mass distribution profile and a probe of structure formation. With thousands of strong lensing galaxy clusters being discovered by current and upcoming surveys, timely, efficient, and accurate core mass estimates are needed. We assess the results of two efficient methods to estimate the core mass of strong lensing clusters: the mass enclosed by the Einstein radius (M(<θ
E), where θ
E is approximated from arc positions, and a single-halo lens model (M
SHM), compared with measurements from publicly available detailed lens models (M
DLM) of the same clusters. We use data from the Sloan Giant Arc Survey, the Reionization Lensing Cluster Survey, the Hubble Frontier Fields, and the Cluster Lensing and Supernova Survey with Hubble. We find a scatter of 18.1% (8.2%) with a bias of −7.1% (1.0%) between

A New Reconstruction of the Sun’s Magnetic Field and Total Irradiance since 1700
Authors: Wang Y.-M. , Lean J. L.
Published: October 2021

We model the Sun’s large-scale magnetic field and total solar irradiance (TSI) since 1700 by combining flux transport simulations with empirical relationships between facular brightening, sunspot darkening, and the total photospheric flux. The photospheric field is evolved subject to the constraints that (1) the flux emergence rate scales as the yearly sunspot numbers, and (2) the polar field strength at solar minimum is proportional to the amplitude of the following cycle. Simulations are performed using both the recently revised sunspot numbers and an average of these numbers and the Hoyt–Schatten group numbers. A decrease (increase) in the polar field strength from one cycle to the next is simulated either by increasing (decreasing) the poleward flow speed, or by decreasing (increasing) the average axial tilts of active regions; the resulting photospheric field evolution is very similar whichever parameter is varied. Comparisons between irradiance data and both the simulated and observed photospheric field suggest that TSI and facular brightness increase less steeply with the field strength at solar minimum than at other phases of the cycle, presumably because of the dominance of small-scale ephemeral regions when activity is very low. This relative insensitivity of the irradiance to changes in the large-scale field during cycle minima results in a minimum-to-minimum increase of annual TSI from 1700 to 1964 (2008) of 0.2 (0.06) W m−2, a factor of 2–3 smaller than predicted in earlier reconstructions where the relation between facular brightness and field strength was assumed to be independent of cycle phase.

. We measured the SZ profiles using the publicly available y-map from the Planck Collaboration as well as our own y-maps constructed from more recent versions of Planck data. The y-map extracted from the latest data release yielded a significant SZ detection out to 3 R
500. In addition, the stacked profile from these data was consistent with simulations that included AGN feedback. Our best-fit model using the latest Planck data suggested a baryon fraction ≈5.6% within R
500. This is significantly lower than the cosmic value of ≈16%, supporting the idea that baryons have been driven to large radii by AGN feedback. Lastly, we discovered a significant (∼3σ) “bump” feature near ∼2 R
500 that is most likely the signature of internal accretion shocks.

White dwarfs play important roles in stellar evolution and help us gauge the age of our galaxy. The white dwarf H1504+65, the hottest known post-asymptotic giant branch star, is peculiar due to its C- and O-rich but He- and H- deficient atmosphere whose composition cannot be well predicted by current stellar evolution models. The analysis of the elemental abundance and the benchmark of stellar atmospheric models depends heavily on spectral data under cosmic conditions, which are currently extremely scarce. We created a well-defined, uniform, relatively large-scale ∼millimeter plasma sample in the laboratory with a temperature and a C/O ratio similar to those of H1504+65’s atmosphere. The emission spectra with high precision in the range of 10–80 nm were obtained and identified according to databases such as NIST and Kelly. A detailed comparison between our emission lines and the Chandra-observed white dwarf H1504+65 atmosphere’s absorption lines was performed. The stongly isolated O VI lines in the range of 10–13 nm are observed in both cases. We observed a wealth of O V lines in the range of 13–14 nm that cannot be well identified or predicted by models due to the weak flux and also probably due to the blending effect of Fe group elements in the Chandra spectrum. Long-wavelength lines ranging from 14 to 80 nm, which are not observed in the Chandra spectrum because of the high interstellar neutral hydrogen column density, show abundant O IV-V, C IV lines, and strong O VI lines. Moreover, the intensities of the lines at 62.973 and 17.216 nm are analyzed to characterize the plasma temperature.

Si les travaux sur les opportunités et sur l’orientation entrepreneuriale des firmes se multiplient dans le champ de l’entrepreneuriat, au point d’en faire des thématiques majeures de ce champ, il semble étonnant que peu de travaux s’interrogent sur leur possible connexion. De ce fait, cette recherche s’interroge sur le possible rapprochement entre le processus de formation d’une opportunité entrepreneuriale au travers des caractéristiques de l’orientation entrepreneuriale de la firme. À cette fin, à partir de propositions de recherche et d’une étude qualitative conduite auprès de huit cas d’entreprises, nous montrons combien l’orientation entrepreneuriale de la firme peut impacter le processus de formation des opportunités entrepreneuriales.
Envers qui doit-on être loyal ? Loyauté et motivations des représailles contre les lanceurs d’alerte
Authors: Fiori-Khayat Coralie
Published: October 2021

Cet article examine les facteurs qui expliquent les représailles contre les lanceurs d’alerte. Les lanceurs d’alerte jouent un rôle important au sein de leur organisation, mais ils sont souvent confrontés à des représailles virulentes. Notre approche s’appuie sur la théorie des ressources sociales et, plus précisément, sur les ressources socio-émotionnelles qui sont échangées dans les organisations sur la durée. Nous proposons un modèle d’analyse fondé sur six propositions, basées sur la théorie des échanges socio-émotionnels. Nous montrons que la force du sentiment négatif contre les lanceurs d’alerte vient de l’idée qu’en s’exprimant, le lanceur d’alerte a manqué à un devoir de loyauté. Mais à qui cette loyauté est-elle due ?
Représentations sociales du consommateur responsable : les autres consommateurs ont-ils vraiment envie de le suivre ?
Authors: Séré de Lanauze Gilles , Lallement Jeanne , de Ferran Florence
Published: October 2021

Existe-t-il un frein de désirabilité sociale associé aux représentations que les gens ont d’un consommateur responsable ? En particulier, la perception d’un ami en tant que consommateur responsable peut-elle freiner la propension à agir selon ses injonctions ? Une étude menée auprès de 363 répondants montre que les intentions d’agir conformément à un message promouvant un comportement responsable sont influencées par l’attitude et la proximité perçue envers l’émetteur du message mais également par les perceptions de ses caractéristiques de consommateur responsable. Certains traits archétypaux du consommateur responsable auraient une influence négative sur les intentions comportementales, en particulier pour les individus moins sensibles aux questions de consommation responsable. Ces résultats contribuent à mieux comprendre le faible pouvoir explicatif des attitudes et injonctions en faveur d’une consommation plus responsable et ouvrent des perspectives d’amélioration en matière de communication pour les acteurs désirant promouvoir de tels arguments, en particulier dans le choix des intermédiaires utilisés pour véhiculer ces arguments.

La terre d’Israël, une question de reconnaissance
Authors: Andrevon Thérèse M. , Forestier Luc , Krisel William , Reijnen Anne Marie
Published: October 2021

La création de l’État d’Israël soulève au sein des Églises la question de la reconnaissance de cette nouvelle réalité et de son interprétation théologique. Du côté juif, cette reconnaissance est attendue parce qu’elle semble prouver que la théologie chrétienne tourne vraiment le dos au mythe du Juif errant. Cet article à plusieurs voix esquisse un état de la question de la position des Églises face à la terre d’Israël dans son contexte contemporain. Il montre la complexité du sujet, tant dans l’Église catholique que chez les différentes tendances au sein du protestantisme. Il met également en lumière la réception parfois ambiguë de cette reconnaissance dans un monde juif pluriel.
Le principe prophétique doit-il conduire à relativiser la terre ? Points de vue protestants
Authors: Reijnen Anne Marie
Published: October 2021

Certaines interprétations protestantes du judaïsme privilégient dans ce dernier la dimension spirituelle et instaurent une hiérarchie où le temps prévaut sur l’espace. Le peuple juif devient alors signe prophétique et critique contre l’idolâtrie du sol. L’établissement de l’État d’Israël divise le protestantisme : enthousiasme et réticence, théologie de la terre et théologie des pauvres s’opposent, en particulier après 1967. Les déclarations protestantes officielles reflètent cette diversité des positions. Nous examinons la transformation des convictions de Paul Tillich suite à ses entretiens amicaux avec Martin Buber. Nous appliquons l’analyse de la « crase » proposée par Jean-Claude Eslin à la polarité entre le principe (prophétique et protestant) et la substance (catholique). Cependant la parousie vient rappeler le caractère encore inachevé de l’œuvre du Christ. Si le protestantisme ne reconnaît pas de « lieux saints », le sacré n’est pas seulement exigence mais aussi donation.
Dynamic simulation methodology for implementing circular economy: A new case study
Authors: Guevara-Rivera Edna , Osorno-Hinojosa Roberto , Zaldivar-Carrillo Victor , Perez-Ortiz Humberto
Published: October 2021

Purpose: Circular economy (CE) principles have evolved in response to natural resource depletion as a set of guidelines for eliminating the linear take-use-dispose model of product consumption. The consequences of shifting from a linear to a circular supply chain are difficult to visualize in the long term. This study aims to design a methodology for building a simulation model to implement CE strategies in any small and medium-sized enterprise SME to prove policies before implementing them in the real world. This paper applied the methodology in a biological cycle case study: a confectionery factory in Mexico.Design/methodology/approach: This study evaluated service-dominant logic, ecosystem services, system dynamics, and agent-based modeling to design the proposed methodology. A series of interviews with stakeholders were performed to assess the simulation model during the development phase. The circular economy indicator prototype (CEIP) was used as a circular maturity measure of the confectionery factory. The simulator was executed in Netlogo software, implementing a four-scenario analysis based on two CE policies for the caramel recycling process. Five state variables were proposed in this analysis: confectionery waste, recycled glucose, recycling utilization, costs of recycled glucose, and profit.Findings: The CEIP score of the confectionery factory was 52%, rated as a “good” product. Regarding scenario analysis, the first scenario had the highest profit improvement.Practical implications: The simulator allowed stakeholders to understand the operation of the recycling process and visualize all variables involved in the system.Originality/value: In the CE literature, little attention has been paid to proposing a methodology for designing a simulation model to implement CE strategies in any industry. Thus, this study implements a nine-step methodology based on services context and dynamic simulation tools to design a platform to evaluate and visualize the consequences of CE strategies implementation in the long term.

There were significant differences in specific depressive symptoms by age group, but no significant difference in total scores on PHQ-9. The depressive subtypes were severe (Class 4), relatively severe (Class 3; with lower psychomotor agitation/retardation and suicidal ideation), moderate (Class 2; with higher psychomotor agitation/retardation and suicidal ideation), and mild depressive symptoms (Class 1). The distribution of depression subtypes is different in various age groups. In the 45–59 age groups, severe symptoms subtype showed the highest ratios (i.e. 50.3%).

Conclusion

This is the first study that analyses depressive symptom characteristics and identifies depressive subtypes in Chinese women with breast cancer across ages to explore symptom heterogeneity. Our findings can contribute to identifying the mechanisms behind these relationships and developing targeted interventions for patients with specific depressive subtypes.
History of Korea Ferroelectric Research
Authors: BU Sang-Don , KIM Ill Won
Published: October 2021

Research Center for Dielectric Study was supported by the Korean Research Foundation from the government. In 1991, Professor Jang, Min-Soo along with 22 other professors, received a research grant of 7 billion won for 10 years, which enabled the Korean Ferroelectric Research Society to be competitive globally. The 9th International Meeting on Ferroelectricity, which is held every four years, was held in Seoul in 1997. The first dielectric joint symposium organized by condensed-matter physics and materials science researchers was held in 2005. The Korean Dielectrics Society was established at Muju resort in 2017, with Professors Tae Won Noh and Jaichan Lee representing the condensed-matter physics and materials science communities, respectively. Currently, more than 300 members are actively participating in the Korean Dielectric Society. To celebrate the 100th anniversary of ferroelectricity, which was fist discovered in Rochelle salt by Joseph Valasek in 1921, we organized a special session in the 2020 Korean Physics Society Fall Meeting.
Sources orales et histoire du cinéma
Authors: Meusy Jean-Jacques
Published: October 2021

Les historiens académiques ont manifesté pendant longtemps de fortes réticences dans l'utilisation des sources orales, considérant qu'elles n'offraient pas de garanties suffisantes de fiabilité. Par ailleurs tandis que le cinéma était encore considéré comme une distraction populaire peu digne d'intérêt, ils ont laissé aux journalistes et aux critiques le soin de construire l'histoire du cinéma. La plupart des grandes histoires générales du cinéma sont ainsi l'œuvre d'historiens autodidactes qui ont tenté d'appliquer les méthodes de l'historiographie avec plus ou moins de rigueur. De leur côté les ethnologues, étudiant des civilisations essentiellement ou complètement orales, ont été parmi les premiers à établir à cette fin des protocoles spécifiques dans le recueil de données. Et les sociologues ont, à leur tour, cherché à élargir les informations fournies par les sources écrites en procédant à des enquêtes orales. Dans le domaine du cinéma, c'est à partir de 1943-1944 qu'Henri Langlois et Musidora entreprennent de recueillir, au moyen de la sténotypie, les souvenirs des vétérans du cinéma dans le cadre de la « Commission de recherche historique » créée au sein de la Cinémathèque française. Pour ce qui est de l'université et de la recherche historique, ce n'est qu'après la Seconde Guerre mondiale, alors que se développaient des techniques d'enregistrement sonore simples d'utilisation, que les sources orales ont fait leur véritable entrée dans l'historiographie et la méthodologie du recueil et du contrôle des témoignages s'est progressivement affinée. Tandis que l'audience de la télévision s'accroissait, de grandes séries d'émissions diffusèrent des entretiens de cinéastes : Cinéastes de notre temps, Histoire du cinéma par ceux qui l'ont fait, etc. que l'ouverture des Inathèques permet actuellement de consulter. Cette collecte de témoignages, qu'elle se fasse au sein des universités, par la télévision ou par d'autres intervenants, a subi des distorsions. La parole a été donnée plus volontiers aux acteurs ainsi qu'aux réalisateurs, portés au premier plan par la politique des auteurs, au détriment de tous les autres artistes, techniciens, distributeurs et exploitants qui, chacun dans sa spécialité de la production à l'exploitation, font aussi que le cinéma existe. Une évolution à cet égard semble toutefois se dessiner.
Henri Storck et l'adaptation cinématographique des romans de Stanislas-André Steeman (1934-1946)
Authors: Janssens Christian
Published: October 2021

Henri Storck est connu comme un documentariste parmi les plus importants des années 1930-1960. Cependant un pan de son activité n'a guère été mis en valeur jusqu'à présent : entre 1934 et 1946, le cinéaste s'est investi dans des projets – non réalisés – d'adaption des romans policiers de Stanislas-André Steeman, tels que le Mannequin assassiné ou la nouvelle Les mains qui parlent qui ont fait les beaux jours de la collection « Le Masque ». À partir des archives du cinéaste, cet article s'efforce de cerner le contexte de production et de mieux comprendre, de la sorte, le genre des films projetés ainsi que certains aspects des scénarios en construction. En particulier, au fil des interventions de différents scénaristes – notamment Yves Mirande et Denis Marion –, comment comprendre les transformations des personnages entre l'œuvre-source et son adaptation pour l'écran ?

Intellectuels et philosophes dans l’Argentine péroniste
Authors: Belloro Lucía Ana
Published: October 2021

« Notre philosophie tente de rétablir le sens de plénitude de l’existence », annonce le président Juan Domingo Perón en s’adressant aux philosophes du monde entier qui participent au Congrès national de philosophie de Mendoza en 1949. Par son discours, le président de l’Argentine se transmute en « philosophe pratique » – comme lui-même se désigne – et transforme radicalement la réunion savante.Dans le contexte de la guerre froide, ce Congrès national de philosophie est l’occasion de rendre publique la troisième posi­tion de son gouvernement. Non sans ambiguïté, le congrès de philosophie est l’une des tentatives parmi d’autres du gouvernement péroniste pour approcher les intellectuels, à une époque où l’espace intellectuel, fortement politisé, se professionnalise et dessine ses frontières disciplinaires.De l’espace intellectuel au sens large, en passant par l’espace universitaire, l’auteure explore dans ce travail la manière dont la politique agit sur l’organisation et la dynamique de l’espace philosophique aussi bien que les débats des philosophes.

Thematic Analysis in Qualitative Research
Authors: Majumdar Anindita
Published: October 2021

The popularity of qualitative methods in social science research is a well-noted and most welcomed fact. Thematic analysis, the often-used methods of qualitative research, provides concise description and interpretation in terms of themes and patterns from a data set. The application of thematic analysis requires trained expertise and should not be used in a prescriptive, linear, and inflexible manner while analyzing data. It should rather be implemented in relation to research question and data availability. To ensure its proper usage, Braun and Clarke have propounded the simplest yet effective six-step method to conduct thematic analysis. In spite of its systematic step-driven process, thematic analysis provides core skills to conduct different other forms of qualitative analysis. Thematic analysis, through its theoretical freedom, flexibility, rich and detailed yet complex analytical account has emerged as the widely used and most effective qualitative research tool in social and organizational context.
African American Single Mothers Thriving Despite Society's Obstacles
Authors: Thomas Carnita Michelle
Published: October 2021

There are myriad reasons why one may be a single mother. From the woman who chose to pursue a career first and in vitro fertilization at an older age, the widow, a divorcee, one who chose to adopt a child alone, someone serving as a foster parent due to their inability to conceive, to the teenage mother. Regardless of the circumstance, society often places a stigma on a single mother without knowing her full story. This is especially true for African American single mothers. This chapter will explore anecdotal experiences of various African American single mothers. It will tap into the circumstances of how the journey began and how these single mothers have navigated their circumstances to defy the odds to attain success.

The Impact on Literacy Instruction Using a Technology Platform
Authors: Sawatsky Rene Lynn
Published: October 2021

Preservice teachers live in a unique world today with the blending of traditional instructional materials for literacy and a variety of high-tech learning technologies present in every 21st century classroom. In the current landscape, teachers are required to learn a variety of technology programs, to know their benefits, and to seamlessly implement them alongside the many pedagogies for maintaining a classroom. This includes teaching a variety of learning strategies and balancing blended online vs. in-person classrooms. This heavy responsibility is compounded by the problem facing many literacy educators today (i.e., how best to instruct within a technology platform and continue to motivate learners to read and to monitor their own use of literacy strategies for comprehension). This chapter outlines a study and subsequent findings of the impact of computer technology for reading strategies instruction with pre-adolescents and its impact for preservice teacher education programs.
A University-Based Reading Clinic and the Pivot to Online Instruction
Authors: Robertson Phyllis M. , Pletcher Bethanie C.
Published: October 2021

This chapter describes the conversion of a face-to-face reading clinic held on a university campus to one implemented fully online. Two faculty members, in different disciplines, worked collaboratively with a local elementary school principal to transition the program to the new format. Teacher candidates from several certification areas worked together in pairs to tutor a shared tutee. The transition to virtual instruction involved rethinking ways to prepare candidates to conduct assessments, plan and implement engaging instruction, and monitor progress in a virtual environment. This chapter will provide a description of this model, along with the logistical and pedagogical decisions made and the lessons learned along the way.
Ocular manifestations in children with developmental delay at a tertiary center in South India
Authors: Hegde Vidya , Jain Rashmi , Bappal Anupama , Shambhu Rashmi
Published: October 2021

PURPOSE:

Developmental delay occurs when a child exhibits a significant delay in the acquisition of milestones, in one or more domains of development. This study was planned to determine the distribution of ocular disorders and to assess the correlation between ocular findings and systemic co morbidity, antenatal and postnatal factors, and perinatal history.

METHODS:

This cross-sectional study included children with developmental delay <16 years of age. All children underwent complete ophthalmological evaluation including full cycloplegic refraction. Vision assessment was done as appropriate for age. Spearman's correlation test was used to analyze the correlation between ocular findings and causes for developmental delay and antenatal, perinatal, and postnatal history.

RESULTS:

A total of 128 children were evaluated. Mean age of the study group was 5.59 ± 2.12 years, 64.8% were males, and 76.6% of children were from rural area. Ocular findings were seen in 110 (85.93%) children, refractive error being the most common finding seen in 87 children (astigmatism n = 47, hypermetropia n = 28, and myopia n = 12). Strabismus was seen in 65 children, esotropia being the most common (n = 36). Vision impairment was present in 39.84% of children. Other ocular findings included disc pallor, cataract, ptosis, amblyopia, keratoconus, telecanthus, lagophthalmos, blepharitis, retinitis pigmentosa, and morning glory syndrome. Spearman's correlation showed no statistical association between ocular findings and various causes for developmental delay. There was a weak negative correlation between antenatal history, mode of delivery, gestational age, and ocular findings.

CONCLUSION:

More than three-fourths of children with developmental delay had ocular findings which necessitates the need for ocular evaluation.
