The aftereffect of the ensemble average of facial expressions on subsequent facial expression recognition
Authors: Minemoto Kazusa , Ueda Yoshiyuki , Yoshikawa Sakiko
Published: February 2022

An ensemble or statistical summary can be extracted from facial expressions presented in different spatial locations simultaneously. However, how such complicated objects are represented in the mind is not clear. It is known that the aftereffect of facial expressions, in which prolonged viewing of facial expressions biases the perception of subsequent facial expressions of the same category, occurs only when a visual representation is formed. Using this methodology, we examined whether an ensemble can be represented with visualized information. Experiment 1 revealed that the presentation of multiple facial expressions biased the perception of subsequent facial expressions to less happy as much as the presentation of a single face did. Experiment 2 compared the presentation of faces comprising strong and weak intensities of emotional expressions with an individual face as the adaptation stimulus. The results indicated that the perceptual biases were found after the presentation of four faces and a strong single face, but not after the weak single face presentation. Experiment 3 employed angry expressions, a distinct category from the test expression used as an adaptation stimulus; no aftereffect was observed. Finally, Experiment 4 clearly demonstrated the perceptual bias with a higher number of faces. Altogether, these results indicate that an ensemble average extracted from multiple faces leads to the perceptual bias, and this effect is similar in terms of its properties to that of a single face. This supports the idea that an ensemble of faces is represented with visualized information as a single face.

В статье приведены результаты исследования направлений повышения эффективности учетно-аналитического обеспечения формирования финансовых результатов для целей составления бухгалтерской и налоговой отчетности, а также управленческого учета, аудита и анализа на основе единых информационных данных. В силу применения различных нормативных документов, регламентирующих порядок расчета прибыли, возникают сложности с идентификацией различных видов доходов и расходов. Для повышения информативности данных о структурных элементах, влияющих на финансовый результат от продаж, разработаны субсчета, детализированные по направлениям деятельности и используемым методам распределения косвенных расходов. Предлагаемая система может применяться для установления взаимосвязи регистров бухгалтерского и налогового учета, корректировки соответствующих разделов отчетности, а также для проведения анализа показателей рентабельности и оптимизации ряда аудиторских процедур на всех этапах проведения проверки.

The article presents the results of a study of ways to improve the efficiency of accounting and analytical support for the formation of financial results for the purposes of accounting and tax reporting, as well as management accounting, audit and analysis based on unified information data. Due to the application of various regulatory documents regulating the procedure for calculating profit, it is difficult to identify various types of income and expenses. To increase the information content of data on structural elements that affect the financial result from sales, sub-accounts have been developed that are detailed by the areas of activity and the methods used for allocating indirect expenses. The proposed system can be used to establish the relationship between the accounting and tax accounting registers, adjust the relevant sections of the financial statements, as well as to analyze the profitability indicators and optimize a number of audit procedures at all stages of the audit.

Published: February 2022

In the context of extreme adaptive optics for large telescopes, we present the Kraken multi-frame blind deconvolution (MFBD) algorithm for processing high-cadence acquisitions, capable of providing a diffraction-limited estimation of the source brightness distribution. This is achieved by a data modeling of each frame in the sequence driven by the estimation of the instantaneous wave front at the entrance pupil. Under suitable physical constraints, numerical convergence is guaranteed by an iteration scheme starting from a compact MFBD, which provides a very robust initial guess that only employs a few frames. We describe the mathematics behind the process and report the high-resolution reconstruction of the spectroscopic binary α And (16.3 mas separation) acquired with the precursor of SHARK-VIS, the upcoming high-contrast camera in the visible for the Large Binocular Telescope.
The Spheromak Tilting and How it Affects Modeling Coronal Mass Ejections
Authors: Asvestari Eleanna , Rindlisbacher Tobias , Pomoell Jens , Kilpua Emilia K. J.
Published: February 2022

Spheromak-type flux ropes are increasingly used for modeling coronal mass ejections (CMEs). Many models aim at accurately reconstructing the magnetic field topology of CMEs, considering its importance in assessing their impact on modern technology and human activities in space and on the ground. However, so far there is little discussion about how the details of the magnetic structure of a spheromak affect its evolution through the ambient field in the modeling domain and what impact this has on the accuracy of magnetic field topology predictions. If the spheromak has its axis of symmetry (geometric axis) at an angle with respect to the direction of the ambient field, then the spheromak starts rotating so that its symmetry axis finally aligns with the ambient field. When using the spheromak in space weather forecasting models, this tilting can happen already during insertion and significantly affects the results. In this paper, we highlight this issue previously not examined in the field of space weather and we estimate the angle by which the spheromak rotates under different conditions. To do this, we generated simple purely radial ambient magnetic field topologies (weak/strong, positive/negative) and inserted spheromaks with varying initial speed, tilt, and magnetic helicity sign. We employ different physical and geometric criteria to locate the magnetic center of mass and axis of symmetry of the spheromak. We confirm that spheromaks rotate in all investigated conditions and their direction and angle of rotation depend on the spheromak’s initial properties and ambient magnetic field strength and orientation.

We present a strong lensing analysis of the galaxy cluster SDSS J1029+2623 at z = 0.588, one of the few currently known lens clusters with multiple images of a background (z = 2.1992) quasar with a measured time delay. We use archival Hubble Space Telescope multiband imaging and new Multi Unit Spectroscopic Explorer follow-up spectroscopy to build an accurate lens mass model, a crucial step toward future cosmological applications. The spectroscopic data enable the secure identification of 57 cluster members and of two nearby perturbers along the line of sight. We estimate the inner kinematics of a subset of 20 cluster galaxies to calibrate the scaling relations parameterizing the sub-halo mass component. We also reliably determine the redshift of four multiply imaged sources, provide a tentative measurement for one system, and report the discovery of a new four-image system. The final catalog comprises 26 multiple images from seven background sources, spanning a wide redshift range, from 1.02 to 5.06. We present two parametric lens models, with slightly different cluster mass parameterizations. The observed positions of the multiple images are accurately reproduced within approximately 0.″2, the three image positions of the quasar within only ∼0.″1. We estimate a cluster projected total mass of M(<300 kpc) ∼ 2.1 × 1014
M
⊙, with a statistical uncertainty of a few percent. Both models, which include a small galaxy close to one of the quasar images, predict magnitude differences and time delays between the quasar images that are consistent with the observations.
No Umbrella Needed: Confronting the Hypothesis of Iron Rain on WASP-76b with Post-processed General Circulation Models

High-resolution spectra are unique indicators of three-dimensional (3D) processes in exoplanetary atmospheres. For instance, in 2020, Ehrenreich et al. reported transmission spectra from the ESPRESSO spectrograph yielding an anomalously large Doppler blueshift from the ultrahot Jupiter WASP-76b. Interpretations of these observations invoke toy model depictions of gas-phase iron condensation in lower-temperature regions of the planet’s atmosphere. In this work, we forward model the atmosphere of WASP-76b with double-gray general circulation models (GCMs) and ray-striking radiative transfer to diagnose the planet’s high-resolution transmission spectrum. We confirm that a physical mechanism driving strong east–west asymmetries across the terminator must exist to reproduce large Doppler blueshifts in WASP-76b’s transmission spectrum. We identify low atmospheric drag and a deep radiative-convective boundary as necessary components of our GCM to produce this asymmetry (the latter is consistent with existing Spitzer phase curves). However, we cannot reproduce either the magnitude or the time-dependence of the WASP-76b Doppler signature with gas-phase iron condensation alone. Instead, we find that high-altitude, optically thick clouds composed of Al2O3, Fe, or Mg2SiO4 provide reasonable fits to the Ehrenreich et al. observations—with marginal contributions from condensation. This fit is further improved by allowing a small orbital eccentricity (e ≈ 0.017), consistent with prior WASP-76b orbital constraints. We additionally validate our forward-modeled spectra by reproducing lines of nearly all species detected in WASP-76b by Tabernero et al. Our procedure’s success in diagnosing phase-resolved Doppler shifts demonstrates the benefits of physical, self-consistent, 3D simulations in modeling high-resolution spectra of exoplanet atmospheres.

Published: February 2022

We investigate the formation of merging binary black holes (BHs) through isolated binary evolution, performing binary population synthesis calculations covering an unprecedentedly wide metallicity range of Population (Pop) I, II, III, and extremely metal-poor (EMP) binary stars. We find that the predicted merger rate density and primary BH mass (m
1) distribution are consistent with the gravitational wave (GW) observations. Notably, Population III and EMP (<10−2
Z
⊙) binary stars yield most of the pair instability (PI) mass gap events with m
1 = 65–130 M
⊙. Population III binary stars contribute more to the PI mass gap events with increasing redshift, and all the PI mass gap events have the Population III origin at redshifts ≳8. Our result can be assessed by future GW observations in the following two points. First, there are no binary BHs with m
1 = 100–130 M
⊙ in our result, and thus the m
1 distribution should suddenly drop in the range of m
1 = 100–130 M
⊙. Second, the PI mass gap event rate should increase toward higher redshift up to ∼11, since those events mainly originate from the Population III binary stars. We find that the following three assumptions are needed to reproduce the current GW observations: a top-heavy stellar initial mass function and the presence of close binary stars for Population III and EMP binary stars, and inefficient convective overshoot in the main-sequence phase of stellar evolution. Without any of the above, the number of PI mass gap events becomes too low to reproduce current GW observations.

Published: February 2022

We report 350 pulsating variable stars found in four DECam fields (∼12 deg2) covering the Antlia 2 satellite galaxy. The sample of variables includes 318 RR Lyrae stars and eight anomalous Cepheids in the galaxy. Reclassification of several objects designated previously to be RR Lyrae as anomalous Cepheids get rid of the satellite’s stars intervening along the line of sight. This in turn removes the need for prolific tidal disruption of the dwarf, in agreement with the recently updated proper motion and pericenter measurements based on Gaia EDR3. There are also several bright foreground RR Lyrae stars in the field, and two distant background variables located ∼45 kpc behind Antlia 2. We found RR Lyrae stars over the full search area, suggesting that the galaxy is very large and likely extends beyond our observed area. The mean period of the RRab in Antlia 2 is 0.599 days, while the RRc have a mean period of 0.368 days, indicating the galaxy is an Oosterhoff-intermediate system. The distance to Antlia 2 based on the RR Lyrae stars is 124.1 kpc (μ
0 = 20.47) with a dispersion of 5.4 kpc. We measured a clear distance gradient along the semimajor axis of the galaxy, with the southeast side of Antlia 2 being ∼13 kpc farther away from the northwest side. This elongation along the line of sight is likely due to the ongoing tidal disruption of Ant 2.

We present the environmental properties around high-z radio galaxies (HzRGs) at z ∼ 4, which have been poorly investigated because of their rarity. We use the largest samples of HzRGs and g-dropout galaxy overdense regions at z ∼ 4, which were constructed from the Hyper Suprime-Cam Subaru Strategic Program, to characterize the HzRG environments statistically. We measure the g-dropout galaxy overdensities around 21 HzRGs whose rest-frame 1.4 GHz radio luminosities (L
1.4 GHz) are 1026–27 W Hz−1. We find that the overdensities around the faint HzRGs with L
1.4 GHz ∼ 1026.0–26.5 W Hz−1 tend to be higher than those of the g-dropout galaxies. On the other hand, no significant difference of density environments is found between the luminous HzRGs with L
1.4 GHz ∼ 1026.5–27.0 W Hz−1 and the g-dropout galaxies. The HzRGs are found to occupy more massive halos than g-dropout galaxies through a cross-correlation between the HzRGs and g-dropout galaxies. This trend is more pronounced in the faint HzRGs. These results are consistent with a scenario where HzRGs get older and more massive as the radio luminosity decreases. The HzRGs are expected to trace the progenitors of Local Cluster halos from their calculated halo mass. In addition, we find that surrounding galaxies tend to distribute along the radio jet major axis of the HzRGs at angular distances of ≲500 physical kpc. Our findings imply the onset of the filamentary structures around the HzRGs at z ∼ 4.
Bayesian Model Selection of Neutron Star Equations of State Using Multi-messenger Observations
Authors: Biswas Bhaskar
Published: February 2022

The measurement of the macroscopic properties of a neutron star, whether in binary or in an isolated system, provides us with a key opportunity to place a stringent constraint on its equation of state. In this paper, we perform Bayesian model selection on a wide variety of neutron star equations of state using multi-messenger observations. In particular, (i) we use the mass and tidal deformability measurements from two binary neutron star merger events, GW170817 and GW190425; and (ii) we use the simultaneous mass–radius measurements of PSR J0030+0451 and PSR J0740+6620 by the NICER collaboration, while the latter has been analyzed by the joint NICER/radio/XMM-Newton collaboration. Among the 31 equations of state considered in this analysis, we are able to rule out different variants of the MS1 family, SKI5, H4, and WFF1 decisively, which are either extremely stiff or soft equations of state. The most preferred equation of state model turns out to be AP3 (or MPA1), which predicts the radius and dimensionless tidal deformability of a 1.4 M
⊙ neutron star to be 12.10 (12.50) km and 393 (513), respectively.
Revision of Immersaria and a new lecanorine genus in Lecideaceae (lichenised Ascomycota, Lecanoromycetes)

Published: February 2022

The species Immersaria cupreoatra has been included in Bellemerea. This caused us to reconsider the relationships between Bellemerea and the lecanorine species of Immersaria and to question the monophyly of Immersaria. Amongst 25 genera of the family Lecideaceae, most have lecideine apothecia, the exceptions being Bellemerea and Koerberiella, which have lecanorine apothecia. According to previous classifications, Immersaria included species with both lecanorine and lecideine apothecia. A five-loci phylogenetic tree (nrITS, nrLSU, RPB1, RPB2, and mtSSU) for Lecideaceae showed that Immersaria was split into two clades: firstly, all the lecideine apotheciate species and secondly, all the lecanorine apotheciate species. The latter clade was closely related to the remaining lecanorine apotheciate genera: Bellemerea and Koerberiella. Therefore, the genus concept of Immersaria is revised accordingly and a new lecanorine genus Lecaimmeria is proposed. Furthermore, four new species for Immersaria and seven new species and three new combinations for the new genus Lecaimmeria are proposed. Keys to Immersaria and the new genus Lecaimmeria are provided.

Published: February 2022

Objective.

Childhood-onset systemic lupus erythematosus (cSLE) has higher rates of lupus nephritis (LN) than adult-onset SLE, often requiring intensive immunosuppression. This study examined North American practices and preferences for the low-dose EuroLupus cyclophosphamide (CYC) protocol, as compared to the high-dose National Institutes of Health (NIH) CYC protocol, to treat LN in cSLE.

Methods.

A 35-item Web-based survey was distributed to Childhood Arthritis and Rheumatology Research Alliance (CARRA) and Pediatric Nephrology Research Consortium (PNRC) providers. The survey assessed participant demographics, CYC prescribing practices, perceptions of EuroLupus protocol, and LN vignette treatment decisions; 1 vignette was taken from a 2009 CARRA survey and responses were compared. Multivariable logistic regression analyzed provider factors associated with use of low- vs high-dose CYC.

Results.

Responses were provided by 185/421 (44%) pediatric rheumatologists (CARRA) and 40/354 (11%) pediatric nephrologists (PNRC). Among respondents who prescribed CYC for pediatric LN over the past year (n = 135), half reported using EuroLupus. When presented with the same vignette about an adolescent with class IV LN, 32% of pediatric rheumatologists chose EuroLupus dosing in 2020, vs 6% in 2009. Provider factors associated with choosing the low-dose regimen were familiarity with the protocol (OR 4.2,P= 0.006) and greater perceived benefit (OR 1.6,P< 0.0001). Pediatric nephrologists had similar responses to the pediatric rheumatology providers. Overall, 78% of respondents perceived EuroLupus protocol efficacy to be equivalent to the high-dose protocol in cSLE LN.

Conclusion.

Pediatric specialists are currently more likely to use low-dose CYC to treat cSLE LN than they were a decade ago. Nevertheless, familiarity with EuroLupus dosing remains low.

Son compte Weibo est devenu, depuis 2016, l’un des comptes muséaux étrangers les plus influents de l’internet chinois. À partir d’une démarche netnographique, nous avons observé l’ensemble des posts émis par le musée du Louvre tout au long de l’année 2019 (N=352) sur Weibo afin d’étudier, à travers le prisme de la diplomatie publique numérique, les stratégies communicationnelles du Louvre sur le net chinois et de comprendre en quoi le musée participait au rayonnement du soft power français en Chine.
La controverse culinaire : la réception de la « calorie » en Belgique, 1890-1913
Authors: Scholliers Peter
Published: February 2022

Cet article porte sur la diffusion du concept de calorie dans la société belge de la Belle Epoque. La « calorie », incarnant le progrès dans la science de la nutrition, veut s’opposer aux idées culinaires courantes. Entre 1890 et 1914, trois vagues de diffusion se suivent. La première est courte mais enthousiaste (1895 environ), la seconde se veut plutôt critique (1900 environ), mais la troisième accueille la « calorie » sans équivoque (1910 environ). Ces conclusions sont basées sur l’étude de journaux belges, en faisant l’hypothèse que ceux-ci reflètent peu ou prou l’opinion courante, tout en contribuant à forger de nouveaux points de vue sur l’alimentation quotidienne.

Published: February 2022

À partir d’une typologie descriptive de sites web français et allemands, portant sur les régimes sans gluten, l’article se propose d’analyser leurs contenus et leur agencement. Le recours à une pluralité de sources de savoirs et de savoir-faire (via des articles de vulgarisation, des récits d’expériences personnelles et des discours visant la promotion d’aliments et d’initiatives) apparaît comme une caractéristique essentielle de leur mode de communication. Par le biais de dispositifs argumentatifs et didactiques, c’est-à-dire en montrant « comment faire » et en expliquant « pourquoi faire », les bloggeurs et bloggeuses participent à la construction d’une culture et d’un mode de vie spécifique et peuvent être vu·e·s comme des « passeurs et passeuses de pratiques ».

L’éducation alimentaire dans les écoles : diffusion, circulation et réappropriation des normes nutritionnelles
Authors: Berthoud Marie
Published: February 2022

Depuis la fin des années 1990, face aux risques sanitaires multiples associés à l’alimentation, les écoles sont devenues un champ d’intervention privilégié pour sensibiliser les enfants à la « bonne » alimentation. En France, diverses instances publiques se sont associées pour concevoir et diffuser de vastes campagnes info-communicationnelles à l’échelle nationale dont l’un des objectifs consiste à éduquer les enfants à un ensemble de normes et valeurs liées à ce qui est aujourd’hui désigné comme sain. Cette étude propose de saisir les enjeux de cette communication publique ainsi que sa circulation d’instance en instance et d’acteur en acteur jusque dans les écoles. Elle s’appuie sur une analyse sémio-pragmatique des dispositifs info-communicationnels et info-pédagogiques produits de 2010 à 2015 par les instances publiques, ainsi que sur des observations participantes et des entretiens semi-directifs dans les écoles. Cette enquête fait apparaître deux logiques à l’œuvre. D’une part, traduits en prescriptions, les messages de santé publique montrent la volonté d’inculquer aux enfants des modèles normatifs afin qu’ils apprennent à diriger par eux-mêmes leurs conduites et celles des autres. D’autre part, ces prescriptions et dispositifs sont adaptés, transformés, réappropriés et détournés de leur objectif premier à chaque étape de leur circulation.
Fiscal Reaction Functions in the EU: A Tale of “r-g” and Whether it Matters
Authors: Afonso António , Alves José , Tovar Jalles João
Published: February 2022

Nous évaluons empiriquement les réponses budgétaires de 28 pays de l’UE au cours de la période 1995T1-2021T2. Dans le même temps, nous évaluons l’importance, pour les réactions d’orientation budgétaire, notamment de la différence entre la croissance économique et les taux d’intérêt à long terme. Nous retrouvons une réponse positive du solde primaire à une augmentation de la dette publique pour le panel de la UE, impliquant un comportement ricardien global. Il existe également des preuves que des politiques budgétaires contra-cycliques ont été menées en moyenne dans cette région géopolitique. L’amélioration du solde primaire à la suite de l’augmentation du ratio dette/PIB est devenue plus pertinente dans la période suivant la crise financière mondiale. Enfin, l’ampleur de la baisse du ratio dette/PIB consécutive à l’amélioration du solde primaire est plus élevée lorsqu’elle est associée à un différentiel taux d’intérêt/taux de croissance positif. Cet effet disparaît en cas de différentiel de taux d’intérêt/taux de croissance négatif. Par conséquent, (r-g) compte, et (r-g)>0 est perçu comme un cas plus critique.
Réforme du cadre budgétaire européen : un argument pour l’adoption d’une règle d’or des finances publiques
Authors: Creel Jérôme
Published: February 2022

Le cadre budgétaire européen repose sur une asymétrie bien connue entre politique monétaire et politique budgétaire, la première confiée à une banque centrale disposant d’une grande indépendance de moyens et dotée d’un mandat portant principalement sur la stabilité des prix, et la seconde contrainte par des limites sur les déficits et les dettes publiques. Cette architecture institutionnelle repose notamment sur la substituabilité stratégique entre ces deux politiques économiques. La crise de Covid-19 a rebattu les cartes en démontrant l’utilité de politiques budgétaires non contraintes et conduit à une réflexion sur une éventuelle réforme du cadre budgétaire européen. Parmi les propositions discutées figure la règle d’or des finances publiques qui permettrait de relancer durablement les investissements publics en Europe. En guise d’argument ou de contre-argument à l’adoption d’une telle règle, nous étudions les interactions entre investissement public et politique monétaire. Les résultats empiriques tendent à montrer qu’investissement public et politique monétaire agissent de manière complémentaire, ce qui justifierait alors de relâcher les contraintes pesant sur les politiques budgétaires. Cela ne devrait cependant pas se faire sans une coopération politique renforcée sur la nature des investissements publics réalisés.
Robust adaptive sliding mode tracking control for a rigid body based on Lie subgroups of SO(3)
Authors: Ye Yaobang , Zuo Zongyu , Basin Michael
Published: February 2022

This paper considers the attitude tracking control problem for a rigid body. In order to avoid the complexity and ambiguity associated with other attitude representations (such as Euler angles or quaternions), the attitude dynamics and the proposed control system are represented globally on special orthogonal groups. An adaptive controller based on a Lie subgroup of SO(3) is developed such that the rigid body can track any given attitude command asymptotically without requiring the exact knowledge of the inertia moment. In the presence of external disturbances, the adaptive controller is enhanced with an additional robust sliding mode term by following the same idea within the framework of SO(3). Finally, simulation results are presented to demonstrate efficiency of the proposed controllers.
A quadrature-based scheme for numerical solutions to Kirchhoff transformed Richards' equation
Authors: Berardi Marco , Difonzo Fabio V.
Published: February 2022

In this work we propose a new numerical scheme for solving Richards' equation within Gardner's framework and accomplishing mass conservation. In order to do so, we resort to Kirchhoff transformation of Richards' equation in mixed form, so to exploit specific Gardner model features, obtaining a linear second order partial differential equation. Then, leveraging the mass balance condition, we integrate both sides of the equation over a generic grid cell and discretize integrals using trapezoidal rule. This approach provides a linear non-homogeneous initial value problem with respect to the Kirchhoff transform variable, whose solution yields the sought numerical scheme. Such a scheme is proven to be \begin{document}$ l^{2} $\end{document}-stable and convergent to the exact solution under suitably conditions on step-sizes, retaining the order of convergence from the underlying quadrature formula.
Monoamine neurotransmitters and mood swings: a dynamical systems approach
Authors: Loula R. , Monteiro L. H. A.
Published: February 2022

Serotonin, dopamine and norepinephrine are monoamine neurotransmitters that modulate our mood state. Hence, imbalances in the levels of these neurotransmitters have been linked to the incidence of several psychiatric disorders. Here, a mathematical model written in terms of ordinary differential equations is proposed to represent the interaction of these three neurotransmitters. It is analytically and numerically shown that this model can experience a Hopf bifurcation. Thus, by varying a parameter value, the neurotransmitter levels can change from a steady state to an oscillatory behavior, which may be at least a partial explanation of the mood swings observed in depressed people.
An optimization model and method for supply chain equilibrium management problem
Authors: Pan Guirong , Xue Bing , Sun Hongchun
Published: February 2022

In this paper, we establish a nonlinear complementarity model and algorithm for supply chain equilibrium management problem consisting of manufacturers, retailers and consumer markets. This work focus on the price of the goods of retailer sell to consumer market in which is a function of the amount of products that are transacted between the retailer and the consumer. Based on this, we investigate the optimizing behavior of the various decision-makers, derive the equilibrium conditions of the manufacturers, the retailers and the consumer markets respectively, and establish a nonlinear complementarity model of this problem. To obtain optimal decision for the problem, we propose a new type of algorithm based on established model, and its global convergence is presented without the assumption of global Lipschitz continuous in detail. The efficiency of given algorithm is also illustrated through some numerical examples.
Sur le néo-animisme technologique à l’ère de l’engouement pour l’Intelligence Artificielle
Authors: Martin-Juchat Fabienne
Published: February 2022

L’engouement actuel pour l’Intelligence Artificielle sous ses formes variées ne s’explique pas uniquement par l’alliance qui s’est nouée entre le capitalisme financier et le développement technologique, ni par la relation qui existe entre l’innovation technologique et l’éco-nomie dite de l’attention. La lecture des anthropologues et des philo­sophes des techniques qui ont analysé les rapports entre techniques et civilisation apparaît essentielle pour comprendre ce qui se joue cultu­rellement dans le développement actuel des technologies intégrant de l’IA. Si l’engouement est général, c’est qu’une axiologie cohérente se déploie à l’échelle mondiale, inscrite certes dans la continuité des valeurs de la modernité, mais également susceptible de répondre à ce qu’on peut identifier comme un besoin généralisé de dépendance affective à la technologie. Plus précisément, ce besoin de dépendance est devenu mondialement prégnant et saillant, car la matérialité tech­nique, grâce aux récentes innovations, est en train de réussir à asso­cier de façon inédite les valeurs de la modernité compatibles avec celles des religions monothéistes, tout en renouant avec des valeurs animistes qui n’ont jamais disparu.
Spiritual Knack Model
Authors: Ahluwalia Gurvinder
Published: February 2022

Spiritual intelligence covers a multitude of qualities; its conceptualization has been the issue of great concern for today's social scientists. The author presented an inclusive model of workplace spirituality, the ‘Spiritual Knack Model'. The first part of the model displayed how the essence of spirituality develops in ‘Shunya', and more to the point, ‘The Growth Cycle' and ‘The Stages of Spirituality' are also explained. Another imperative concept, ‘Spiritual Knack Virtues', is obtained from this chapter. This fourteen-dimensional map gives details of the significant features of a spiritually oriented person. The last part of the model comprises the detail of the process and activities related to ‘Development of Spiritual Values' amongst employers and employees for the augmentation of the holistic productivity of the organizations.
Impact of Workplace Spirituality in Reducing Emotional Labour Among Academics
Authors: Sharma Nidhi
Published: February 2022

It has been long recognized that everyone wears an emotional mask. Specially, in the context of the service sector, job requirements mandate display rules requiring the expression of certain emotions that may not necessarily be felt by employees. Such regulation of emotions often leads to stress and burnout that negatively impact employees' physical and psychological health. Emotional labour is thus a worrisome phenomenon. Against this backdrop, this chapter concerns itself with finding solutions that could potentially alleviate the associated problems of personal and organizational well-being. Extant literature observes numerous suggestions about these detrimental effects being mitigated by spirituality. Academics recommend that organizations could employ workplace spirituality initiatives to replenish the emotional resources exhausted due to emotional labour. This chapter thus addresses the empirical association between workplace spirituality and emotional labour among teachers in higher education sector – the service professionals claimed to be most negatively impacted by emotional labour.
The Structure of the LEAD Program
Authors: Palazzolo Alyssa N. , Pizzo Dana L.
Published: February 2022

The L.E.A.D. program originally started as a secondary model for service learning to assist local secondary schools with Student Success Initiatives. As the L.E.A.D. Program matured, it expanded to the elementary level. This chapter briefly touches upon the origins of L.E.A.D. as it relates to the structure of the program (theoretical and practical). The theoretical (course-based) component of the program will be outlined in terms of the types of lectures, workshops, activities, and presentations in which L.E.A.D. teacher candidates participate. The practical (field placement) component of the program will be explained in terms of placement requirements and potential L.E.A.D. involvement. Similarities and differences between the elementary and secondary models will also be explained.
Using Service-Learning Field Placements to Radically Transform Teacher Education From the Inside Out
Authors: Carlson Jennifer , Strait Jean
Published: February 2022

The current educational landscape is more complex and demanding than ever. The integration of service-learning into teacher education programs increase opportunities for intersectionality of curriculum, the development of cultural humility, use of contact theory, and hands-on learning. The partnership between an urban liberal arts university and suburban school district resulted in the College Pals model. The College Pals model acknowledges that pre-service teachers need to learn how to navigate systems that are familiar to their students in order to positively impact student learning and educational experiences. Service-learning as a pedagogical approach enhances instructional readiness through earlier opportunities to work in and connect to classrooms prior to their matriculated field experiences and provide an effective integration of community-oriented approaches to teacher education.
Community-Based Field Experiences in Teacher Education
Authors: Hallman Heidi L.
Published: February 2022

This chapter proposes the value of offering teacher candidates an opportunity to participate in community-based field experiences during their teacher education programs. Community-based field experiences, in contrast to traditional, classroom-based placements usually offered at this stage in prospective teachers' professional preparation, enable beginning teachers to conceptualize their own learning and the learning of their students in new ways. As part of teacher education programs, the community-based field experience serves a distinct purpose and place, and one that is often underexplored. This chapter describes the integration of community-based field experiences into teacher education programs and discusses the unique quality of community-based settings as potential sites for teachers' learning.
