This book examines a structural equation model that explores the relationship between hedonic and utilitarian behaviors of shopping mall customers and store loyalty. Shopping malls are considered important spaces representing the economic and social aspects of modern cities. The book discusses the spatial structure of cities and the role of shopping malls as public spaces in the first chapter. Elements such as fast-food restaurants, chain stores, entertainment centers, cinemas, electronics stores, fairgrounds, exhibition areas, and prayer rooms in shopping malls are examined. Additionally, the use of shopping malls as leisure spaces and their function as secure areas are also discussed. The second chapter focuses on the historical transformation, exterior designs, and architectures of shopping malls. The historical journey of shopping malls in Turkey is also examined in this chapter. Lastly, the book analyzes the image of shopping malls and the relationship between customers' hedonic and utilitarian behaviors and store loyalty. This study serves as an important resource for understanding the behaviors of shopping mall customers and increasing customer loyalty towards shopping malls.

About Christian Aspects of S. A. Yesenin’s Ethnopoetics in the 1910s
Authors: Федосеева Т.В.
Published: March 2021

В статье исследуется вопрос о поэтическом выражении православного сознания в лирике С. А. Есенина 1910-х годов. Анализ избранных произведений осуществляется с применением методологии и терминологии, актуальной для современного литературоведения этнопоэтики. Материал исследования включает текст теоретического трактата «Ключи Марии» как итоговый для данного периода и определяющий для творческого метода поэта. Рассматриваются случаи жанрового влияния народной духовной поэзии на формально-содержательную характерность произведений Есенина. Выявляются пути развития в лирике поэта народнопоэтических жанровых моделей предания, сказания, духовной песни. Устанавливается ментальный уровень поэтики, определенный категориями «дарения и нищелюбия», «веры в чудо». В образе лирического героя выделяются в качестве характерологических мотивы странничества, греха, покаяния. В пространственно-временной и сюжетно-мотивной характерности произведений исследуемого периода выделяется мистериальная поэтика. Из лирического комплекса 1918–1919 годов выделяется сюжет, соотносимый с мотивами умирания и Божественного претворения плоти. Автор статьи приходит к выводу
о необходимости уточнения выраженного в творчестве Есенина 1910-х годов типа художественного сознания термином «народное православие». Результаты проведенного исследования указывают на возможности дальнейшего изучения творчества поэта в предложенном направлении.

The article investigates the issue of poetic manifestations of Christian worldview in S. A. Yesenin’s poetry in the 1910s. The analysis of selected poems is performed by means of ethnopoetics relevant for modern literary studies. The author of the article investigates the theoretical treatise “Maria’s Keys” as a work characteristic of the aforementioned period and of the poet’s creative method. The article treats the influence of religious folk poetry on the content and form of Yesenin’s verse. It investigates the way folk tales, legends and spiritual songs influenced Yesenin’s poetry. The article shows that Yesenin’s poems abound in such concepts as generosity, benevolence to the poor, belief in the reality of miracles. The lyrical hero of Yesenin’s poems is described through the prism of such concepts as pilgrimage, sin, repentance. The spatial, temporal, and thematic characteristics of Yesenin’s poems of the aforementioned period are mystery-related. Yesenin’s poems of 1918–1919 abound in motifs of death and resurrection. The author of the article maintains that it is not only feasible but also necessary to further investigate the motifs of folk Christianity characteristic of Yesenin’s works of the 1910s.

Performance Analysis of Highway Wind Turbine Enhanced with Wind Guide Vanes Using the Taguchi Method
Authors: Mazlan Mohamad Zahid , Mohd Zawawi Fazila , Tahzib Teeab , Ismail Kamarulafizam , Samion Syahrullail
Published: March 2021

Considerable efforts have been made by researchers to study the interaction between moving vehicles and wind turbines. The Savonius vertical-axis wind turbine was chosen due to its effectiveness in low-wind speed conditions. Speeding vehicles produce a scattered and non-uniform wind flow with disturbances. Hence, to prevent a negative torque, a row of wind guide vane panels was arranged in front of the blades of a wind turbine. The wind guide vane had the shape of an NACA4412 aerofoil to reduce the loss of wind energy, and to further increase wind velocity. A number of CFD simulations were designed using the Taguchi method to determine the optimum conditions for the power coefficient of the wind turbine in terms of the effects of three factors, namely, the distance between the guide vanes (d), the angle of the guide vanes (?), and the speed of the moving car (VC). An orthogonal array of L9(33) was designed. In addition, to observe the effects of the wind velocity induced by the moving vehicle, the wind turbine was incorporated with one degree of freedom (1DOF). The results showed that the speed of the moving car played a major role in determining the power coefficient. The order of influence of each factor was ranked as VC > ? > d. The performance of the wind turbine was sensitive to the speed of the car and the angle of the guide vanes, whereas it was insensitive to the distance between the guide vanes. Furthermore, the analysis of the signal-to-noise (S/N) ratio suggested that the optimal combination of factors for a maximum power coefficient were d = 0.4m, ? = 30°, and VC =30m/s. The optimum setting increased the Cp to 26% compared to the Cp that was produced without the installation of the guide vanes.

Türkiye’de afet yönetimi açısından bulaşıcı hastalıklar konusunda çok az araştırma bulunmaktadır. Bu araştırma, Türkiye’nin yakın tarihinde (1956-2017) maruz kaldığı bulaşıcı hastalıkları incelemek ve gelecekte olası bir felaketin zararlarını en aza indirmek için ne yapılması gerektiği konusunda rehberlik sağlamak amacıyla planlanan bir araştırmadır.
Bu araştırma, tanımlayıcı tipte ve retrospektif kohort özelliğinde bir araştırmadır. Araştırmanın verileri 1956-2017 yılları arasında Sağlık Bakanlığı tarafından yayınlanan “istatistik yıllıklarından” elde edilmiştir. Veriler bilgisayar ortamında analiz edilmiştir. Bu yıllıklarda 23 bulaşıcı hastalık türü tespit edilmiştir ve insidans oranları yıllara göre hesaplanmıştır.
2004 ve öncesi yıllara ait yıllıklarda bulaşıcı hastalık verilerine daha fazla önem verildiği görülmektedir. Son yıllara ait istatistik yıllıklarında ise sınırlı sayıda hastalık (Verem, Sıtma, Kızamık ve AIDS) için çok az veri yayınlanmaktadır. Yasal zorunluluk olsa da; Türkiye’de bulaşıcı hastalıkların bildirimi yeterli değildir. İstatistik yıllıklarında sınırlı verilerin yayınlanması, afet yönetimi açısından bulaşıcı hastalıklara dair risk analizini zorlaştırmaktadır. Bulaşıcı hastalıklar açısından; tüberküloz insidansı 1960-1969 yılları arasında, sıtma insidansı 1980-1989 yılları arasında, kızamık insidansı 1960-1970 yılları arasında en yüksek seviyededir. Türkiye’de bulaşıcı hastalıkların görülme sıklığını azaltmak ve salgınları önlemek için etkili ve kapsamlı bir sürveyans, erken müdahale ve müdahale altyapısı kurulması önerilmiştir.

Authors: CAN GÜR Ganime , YILMAZ Emine
Published: March 2021

This research was planned in randomized controlled trial in order to reveal the effect of intercultural nursing training on cultural sensitivity and empathic tendency level among nursing students. 120 students were included in the sample group. Students in the study group attended in intercultural nursing training 2 hours a week for 8 weeks. There was no application for the students in the control group. Descriptive statistics, independent and dependent t tests were used to appraise the data. It was observed in the study that before the training, the cultural sensitivity total score of both control and training groups was at moderate level. After training: the total Empathic Tendency Scale score of the training group was higher than the control group’s and the training group’s total scores for Intercultural Sensitivity Scale, subdimensions regarding interaction engagement and attentiveness, and respect for cultural difference were higher than the control group. The results of the research showed that intercultural training was effective in increasing the intercultural sensitivity and empathic tendency level and enabling the students to acquire empathy skills. As a result, it has been observed that intercultural training is effective on students' gaining empathy skills.

The growth of the church is God's will, so this goal is a priority for God's church. The growth of the church cannot be separated from the character Peter who is a disciple who was asked by the Lord Jesus to shepherd His people. Church growth cannot be separated from the attitude of church leaders (pastors), therefore the problem discussed in this study is how to increase church growth through the attitude of the church pastor based on 1 Peter 5: 2-3. By researching and answering the formulation of this problem, it is hoped that the leaders of the congregation and congregation will have knowledge and attitudes that are in accordance with the word of God, and finally church growth is experienced by all churches.Pertumbuhan gereja merupakan kehendak Allah, sehingga sasaran ini menjadi prioritas bagi gereja Tuhan. Pertumbuhan gereja tidak bisa dipisahkan dari tokoh Petrus yang merupakan murid yang diminta Tuhan Yesus untuk menggembalakan umat-Nya.  Pertumbuhan gereja pun tidak dapat dipisahkan dari sikap pemimpin jemaat (gembala), oleh sebab itu masalah yang dibahas dalam penelitian ini adalah bagaimana meningkatkan pertumbuhan gereja melalui sikap gembala jemaat berdasarkan 1 Petrus 5:2-3. Dengan meneliti dan menjawab rumusan masalah ini diharapkan para pemimpin jemaat dan jemaat memiliki pengetahuan dan sikap yang sesuai firman Allah, dan akhirnya pertumbuhan gereja dialami oleh semua gereja.

Searching for Low-mass Population III Stars Disguised as White Dwarfs
Authors: Chandra Vedant , Schlaufman Kevin C.
Published: March 2021

It is uncertain whether or not low-mass Population III stars ever existed. While limits on the number density of Population III stars with M
* ≈ 0.8 M
⊙ have been derived, using Sloan Digital Sky Survey (SDSS) data, little is known about the occurrence of Population III stars at lower masses. In the absence of reliable parallaxes, the spectra of metal-poor main-sequence (MPMS) stars with M
* ≲ 0.8 M
⊙ can easily be confused with those of cool white dwarfs. To resolve this ambiguity, in this paper we present a classifier that differentiates between MPMS stars and white dwarfs, based on photometry and/or spectroscopy without the use of parallax information. We build and train our classifier using state-of-the-art theoretical spectra, and evaluate it on existing SDSS-based classifications for objects with reliable Gaia DR2 parallaxes. We then apply our classifier to a large catalog of objects with SDSS photometry and spectroscopy to search for MPMS candidates. We discover several previously unknown, extremely metal-poor (EMP) candidate stars, and recover numerous confirmed EMP stars already noted in the literature. We conclude that archival SDSS spectroscopy has already been exhaustively searched for EMP stars. We predict that the lowest-mass stars of primordial composition will have redder optical-to-infrared colors than cool white dwarfs at constant effective temperature, due to surface gravity-dependent collision-induced absorption from molecular hydrogen. We suggest that the application of our classifier to data produced by next-generation spectroscopic surveys will set stronger constraints on the number density of low-mass Population III stars in the Milky Way.
Observable Predictions from Perturber-coupled High-eccentricity Tidal Migration of Warm Jupiters
Authors: Jackson Jonathan M. , Dawson Rebekah I. , Shannon Andrew , Petrovich Cristobal
Published: March 2021

The origin of warm Jupiters (gas giant planets with periods between 10 and 200 days) is an open question in exoplanet formation and evolution. We investigate a particular migration theory in which a warm Jupiter is coupled to a perturbing companion planet that excites secular eccentricity oscillations in the warm Jupiter, leading to periodic close stellar passages that can tidally shrink and circularize its orbit. If such companions exist in warm Jupiter systems, they are likely to be massive and close-in, making them potentially detectable. We generate a set of warm Jupiter-perturber populations capable of engaging in high-eccentricity tidal migration and calculate the detectability of the perturbers through a variety of observational metrics. We show that a small percentage of these perturbers should be detectable in the Kepler light curves, but most should be detectable with precise radial velocity measurements over a 3 month baseline and Gaia astrometry. We find these results to be robust to the assumptions made for the perturber parameter distributions. If a high-precision radial velocity search for companions to warm Jupiters does not find evidence of a significant number of massive companions over a 3 month baseline, it will suggest that perturber-coupled high-eccentricity migration is not the predominant delivery method for warm Jupiters.
A Distinct Population of Small Planets: Sub-Earths
Authors: Qian 钱 Yansong 岩松 , Wu 武 Yanqin 延庆
Published: March 2021

The sizes of small planets are known to be bimodal, with a gap separating planets that have lost their primordial atmospheres (super-Earths) and the ones that retain them (mini-Neptunes). Here, we report evidence for another distinct population at smaller sizes. By focusing on planets orbiting around GK dwarfs inward of 16 days and correcting for observational completeness, we find that the number of super-Earths peaks around 1.4 Earth radii and disappears shortly below this size. Instead, a new population of planets (sub-Earths) appears to dominate at sizes below ∼1 Earth radius, with an occurrence that increases with decreasing size. This pattern is also observed in ultra-short-period planets. The end of super-Earths supports earlier claims that super-Earths and mini-Neptunes, planets that likely form in gaseous protoplanetary disks, have a narrow mass distribution. Sub-Earths, in contrast, can be described by a power-law mass distribution and may be explained by the theory of terrestrial planet formation. We therefore speculate that they are formed well after the gaseous disks have dissipated. The extension of these sub-Earths toward longer orbital periods, currently invisible, may be the true terrestrial analogs. This strongly motivates new searches.

Published: March 2021

We characterize the kinematic and chemical properties of 589 Galactic anticenter substructure stars (GASS) with K/M giants in integrals-of-motion space. These stars likely include members of previously identified substructures such as Monoceros, A13, and the Triangulum-Andromeda cloud. We show that these stars are in nearly circular orbits on both sides of the Galactic plane. We can see a velocity (V

Z
) gradient along Y-axis especially for the south GASS members. Our GASS members have similar energy and angular momentum distributions to thin-disk stars. Their location in [α/M] versus [M/H] space is more metal-poor than typical thin-disk stars, with [α/M] lower than that of the thick disk. We infer that our GASS members are part of the outer metal-poor disk stars and that the outer disk extends to 30 kpc. Considering the distance range and α-abundance features, GASS could be formed after the thick disk was formed due to the molecular cloud density decreasing in the outer disk where the star-formation rate might be less efficient compared to the inner disk.
On the Shapes of Interstellar Grains: Modeling Infrared Extinction and Polarization by Spheroids and Continuous Distributions of Ellipsoids
Authors: Draine B. T. , Hensley Brandon S.
Published: March 2021

Although interstellar grains are known to be aspherical, their actual shapes remain poorly constrained. We assess whether three continuous distributions of ellipsoids (CDEs) from the literature are suitable for describing the shapes of interstellar grains. Randomly selected shapes from each distribution are shown as illustrations. The often-used Bohren–Huffman CDE includes a very large fraction of extreme shapes: fully 10% of random draws have axial ratio a
3/a
1 > 19.7, and 5% have a
3/a
1 > 33. The CDE2 distribution includes a much smaller fraction of extreme shapes, and appears to be the most realistic. For each of the three CDEs considered, we derive shape-averaged cross sections for extinction and polarization in the Rayleigh limit. Finally, we describe a method for “synthesizing” a dielectric function for an assumed shape or shape distribution if the actual absorption cross sections per grain volume in the Rayleigh limit are known from observations. This synthetic dielectric function predicts the wavelength dependence of polarization, which can then be compared to observations to constrain the grain shape.
An Updated Formalism for Line-driven Radiative Acceleration and Implications for Stellar Mass Loss
Authors: Lattimer Aylecia S. , Cranmer Steven R.
Published: March 2021

Radiation contributes to the acceleration of large-scale flows in various astrophysical environments because of strong opacity in the spectral lines. Quantification of the associated force is crucial to understanding these line-driven flows, and a large number of lines (due to the full set of elements and ionization stages) must be taken into account. Here we provide new calculations of the dimensionless line strengths and associated opacity-dependent force multipliers for an updated list of approximately 4.5 million spectral lines compiled from the NIST, CHIANTI, CMFGEN, and TOPbase databases. To maintain generality of application to different environments, we assume local thermodynamic equilibrium, illumination by a Planck function, and the Sobolev approximation. We compute the line forces in a two-dimensional grid of temperatures (i.e., values between 5200 and 70,000 K) and densities (varying over 11 orders of magnitude). Historically, the force multiplier function has been described by a power-law function of optical depth. We revisit this assumption by fitting alternate functions that include saturation to a constant value (Gayley’s

Q

¯

parameter) in the optically thin limit. This alternate form is a better fit than the power-law form, and we use it to calculate example mass-loss rates for massive main-sequence stars. Because the power-law force multiplier does not continue to arbitrarily small optical depths, we find a sharp decrease, or quenching, of line-driven winds for stars with effective temperatures less than about 15,000 K.
Radiation Hydrodynamics Simulations of Protoplanetary Disks: Stellar Mass Dependence of the Disk Photoevaporation Rate
Authors: Komaki Ayano , Nakatani Riouhei , Yoshida Naoki
Published: March 2021

Recent multiwavelength observations suggest that inner parts of protoplanetary disks (PPDs) have shorter lifetimes for heavier host stars. Since PPDs around high-mass stars are irradiated by strong ultraviolet radiation, photoevaporation may provide an explanation for the observed trend. We perform radiation hydrodynamics simulations of photoevaporation of PPDs for a wide range of host star mass of M

scales with the adopted far-ultraviolet and X-ray luminosities. We derive the surface mass-loss rates and provide polynomial function fits to them. We also develop a semianalytic model that well reproduces the derived mass-loss rates. The estimated inner-disk lifetime decreases as the host star mass increases, in agreement with the observational trend. We thus argue that photoevaporation is a major physical mechanism for PPD dispersal for a wide range of the stellar mass and can account for the observed stellar mass dependence of the inner-disk lifetime.
The Connection between Warm Carbon-chain Chemistry and Interstellar Irradiation of Star-forming Cores
Authors: Kalvāns Juris
Published: March 2021

Some observations of warm carbon-chain chemistry (WCCC) cores indicate that they are often located near the edges of molecular clouds. This finding may suggest that WCCC is promoted in star-forming cores exposed to radiation from the interstellar medium. We aim to investigate the chemistry of carbon chains in such a core. A chemical simulation of a gas parcel in a low-mass star-forming core with a full level of irradiation by interstellar photons and cosmic rays was compared to a simulation of a core receiving only 1/10 of such irradiation. In the full irradiation model, the abundances of carbon chains were found to be higher by a factor of a few to a few hundred, compared to the model with low irradiation. Higher carbon-chain abundances in the prestellar stage and, presumably, in the extended circumstellar envelope arise because of irradiation of gas and dust by interstellar photons and cosmic rays. A full standard rate of cosmic-ray-induced ionization is essential for a high carbon-chain abundance peak to occur in the circumstellar envelope, which is heated by the protostar (the “true” WCCC phenomenon). The full irradiation model has lower abundances of complex organic molecules than the low-irradiation model. We conclude that WCCC can be caused by exposure of a star-forming core to interstellar radiation, or even just to cosmic rays. The Appendix describes an updated accurate approach for calculating the rate of cosmic-ray-induced desorption.

The detection of phosphorous-bearing molecules in interstellar environments constitutes a fundamental task for understanding the formation of prebiotic molecules, but it is also a challenge. In cold interstellar environments, where rich chemistry is expected to happen, only PN and PO have been detected. Phosphine (PH3) must also play an essential role in these regions, since P is expected to deplete onto dust grains significantly, and hydrogenation reactions are dominant in such environments. Surface chemistry on dust grains shows a particular idiosyncrasy where an equilibrium between competitive reactions, photoconversion processes, and desorption are in continuous interplay, modifying both the dust composition and the gas composition. In this study, we theoretically study in detail the interconversion of P to PH3 via subsequent additions of H on cold dust grain analogs. For all reactions, we provide the binding energy of the adsorbates, reaction energies, and, when present, activation barriers and tunneling-corrected rate constants. We also present an estimate of the desorption temperature of these species based on transition state theory. Using recently available experimental results on PH3 desorption via chemical reactions, we conclude that all of the intermediate products of the hydrogenation sequence to phosphine may be released to the gas phase.

The algal flora of the Island of Santa Maria (eastern group of the Azores archipelago) has attracted interest of researchers on past occasions (Drouët 1866, Agardh 1870, Trelease 1897, Schmidt 1931, Ardré et al. 1974, Fralick and Hehre 1990, Neto et al. 1991, Morton and Britton 2000, Amen et al. 2005, Wallenstein and Neto 2006, Tittley et al. 2009, Wallenstein et al. 2009a, Wallenstein et al. 2010, Botelho et al. 2010, Torres et al. 2010, León-Cisneros et al. 2011, Martins et al. 2014, Micael et al. 2014, Rebelo et al. 2014, Ávila et al. 2015, Ávila et al. 2016, Machín-Sánchez et al. 2016, Uchman et al. 2016, Johnson et al. 2017, Parente et al. 2018). Nevertheless, the Island macroalgal flora is not well-known as published information reflects limited collections obtained in short-term visits by scientists. To overcome this, a thorough investigation, encompassing collections and presence data recording, was undertaken at both the littoral and sublittoral levels down to a depth of approximately 40 m, covering an area of approximately 64 km2. The resultant taxonomic records are listed in the present paper which also provides information on species ecology and occurrence around the Island, improving, thereby, the knowledge of the Azorean macroalgal flora at both local and regional scales.

A total of 2329 specimens (including some taxa identified only to genus level) belonging to 261 taxa of macroalgae are registered, comprising 152 Rhodophyta, 43 Chlorophyta and 66 Ochrophyta (Phaeophyceae). Of these, 174 were identified to species level (102 Rhodophyta, 29 Chlorophyta and 43 Ochrophyta), encompassing 52 new records for the Island (30 Rhodophyta, 9 Chlorophyta and 13 Ochrophyta), 2 Macaronesian endemics (Laurencia viridis Gil-Rodríguez & Haroun; and Millerella tinerfensis (Seoane-Camba) S.M.Boo & J.M.Rico), 10 introduced (the Rhodophyta Acrothamnion preissii (Sonder) E.M.Wollaston, Antithamnion hubbsii E.Y.Dawson, Asparagopsis armata Harvey, Bonnemaisonia hamifera Hariot, Melanothamnus harveyi (Bailey) Díaz-Tapia & Maggs, Scinaia acuta M.J.Wynne and Symphyocladia marchantioides (Harvey) Falkenberg; the Chlorophyta Codium fragile subsp. fragile (Suringar) Hariot; and the Ochrophyta Hydroclathrus tilesii (Endlicher) Santiañez & M.J.Wynne, and Papenfussiella kuromo (Yendo) Inagaki) and 18 species of uncertain status (11 Rhodophyta, 3 Chlorophyta and 4 Ochrophyta).
Maratus nemo: A new wetland species of peacock spider from South Australia (Araneae, Salticidae, Euophryini)
Authors: Schubert Joseph
Published: March 2021

A new species of peacock spider, Maratus nemosp. nov., is described from the vicinities of Mount McIntyre and Nangwarry, South Australia. Unusual among members of its genus, the new species appears to inhabit ephemeral wetland complexes on marshy vegetation in shallow water. The discovery of Maratus nemosp. nov. is one of several recently described species attributed to the growing interest in amateur invertebrate macrophotography, with putative new species brought to attention of taxonomists through social media engagement.
FAIR and open multilingual clinical trials in Wikidata and Wikipedia
Authors: Rasberry Lane , Mietchen Daniel
Published: March 2021

This project seeks to conduct language translation on metadata labels for research publications, attribution data, and clinical trials information to make data about medical research queriable in underserved languages through Wikidata and the Linked Open Web. This project has the benefit of distributing content through Wikipedia and Wikidata, which already have an annual userbase of a billion users and which already have established actionable standards to practice diversity, inclusion, openness, FAIRness, and transparency about program development. The impact will be localized access to basic research information in various Global South languages to integrate with existing community efforts for establishing the same. Although Wikidata development in this direction seems inevitable, the cultural and social exchange required to establish global multilingual research partnerships could begin now with support rather than later as a second phase effort for including the developing world. Wikipedia and Wikidata are established forums with an existing active userbase for multilingual research collaboration, but the research practices there still are immature. By applying metadata expertise through this project, we will elevate the current amateur development with more stable Linked Open Data compatibility to English language databases. Using the wiki distribution and discussion platform to develop the global conversation about data sharing will set good precedents for the trend of global research collaboration.
Census of the fruit and flower chafers (Coleoptera, Scarabaeidae, Cetoniinae) of the Macau SAR, China
Authors: Perissinotto Renzo , Clennell Lynette
Published: March 2021

The coleopteran fauna of the Macau SAR in southern China has historically received only limited attention and no updated information has been published since the last substantial works produced in the 1990s. An annotated and illustrated review of the fruit and flower chafers (Scarabaeidae, Cetoniinae) of this region is here presented, in order to provide an account of the current status of the taxonomic diversity and ecology of this important insect group. Eleven species were observed in the SAR during an intense investigation undertaken during the period 2017–2020, with six of these representing new records for Macau and two for the broader region of the Pearl River Delta, also known as the Greater Bay Area. Although this census leads to a substantial increase in the number of species known for the area, it also highlights the threats that the recent escalation in urban development and land-use transformation are posing to a number of species which seem unable to maintain a sustainable population in the region, mainly due to habitat destruction.

Programmation de l’action et planification du travail : des enjeux langagiers pour la formation professionnelle
Authors: Filliettaz Laurent
Published: March 2021

Cet article explore quelques contributions des discours programmateurs à l’étude des processus de professionnalisation. Il propose d’abord une clarification à caractère théorique, visant à mieux comprendre le concept même de discours programmateur et les ingrédients notionnels qui s’y trouvent combinés. Il se poursuit par une étude empirique, dans laquelle ce cadre conceptuel est mobilisé pour décrire les processus de programmation de l’action dans le champ de la formation professionnelle des éducatrices et éducateurs de l’enfance. Une analyse de données interactionnelles orales montre comment l’activité d’une étudiante stagiaire est préparée et programmée par la tutrice qui encadre son stage ; elle montre ensuite comment la stagiaire s’approprie ces consignes pour programmer à son tour l’activité éducative adressée aux enfants.
S’approprier des connaissances encyclopédiques : le cas de la leçon d’histoire entre fiction et documentaire
Authors: Le Guern Odile
Published: March 2021

Après une mise au point terminologique entre enseignement, apprentissage transmission et acquisition, cet article examine les processus d’appropriation de connaissances encyclopédiques qui sont proposés à des élèves de l’école primaire à travers l’analyse de deux manuels publiés en 1954 et 2002. La perspective est donc diachronique pour révéler une évolution des pratiques pédagogiques. Ces supports et leur utilisation par l’enseignant proposent des stratégies pédagogiques différentes, soit en les imposant sans que l’élève puisse les décrypter (dans une démarche d’enseignement et de transmission), soit en les explicitant et en impliquant l’élève (dans une démarche d’apprentissage dont la visée est l’acquisition). Le manuel de 1954 ‹raconte› l’histoire aux enfants, sur un mode proche de la fiction, pour expliquer l’Histoire. Celui de 2002 met directement l’élève en posture de chercheur en mesure de construire lui-même son savoir.
La gestion du risque dans la ville : patterns procéduraux dans les guides d’information et de prévention
Authors: Basso Fossali Pierluigi , Thiburce Julien
Published: March 2021

L’analyse sémiotique et linguistique d’un guide de prévention des risques industriels majeurs et d’une affiche instruisant les actions à accomplir en cas d’attaques terroristes vise à montrer comment l’organisation verbale et graphique est exploitée pour communiquer les risques et pour devenir un support pour la schématisation, l’appropriation et l’exécution des procédures d’urgence. Pour ces textes, il faut prévoir un design de la communication qui est doté d’un caractère prescriptif mais qui a besoin aussi d’une rhétorique de l’appropriation responsable et complice, visant à distribuer les poids modaux entre les interactants. Dès lors, quelle place faire à l’interlocuteur dans le discours sur le risque ? Un objectif non secondaire de cette recherche est la tentative de faire émerger les variantes et les invariants du discours programmateur, ses sous-types et sa compénétration avec d’autres types de discours.
Se mobiliser et travailler à l’hôpital par temps de Covid
Authors: Banes Noémie , Plumet Orianne , Beaudevin Claire , Vincent Fanny
Published: March 2021

Le Collectif Inter-Urgences est un collectif de soignant·es né au printemps 2019 pendant la grève initiée par les infirmières et les aides-soignantes de 5 services d’urgences publics parisiens. Face à l’extension de la mobilisation à tous les services d’urgences de l’Assistance Publique-Hôpitaux de Paris, puis au-delà de l’Île-de-France, le Collectif a porté trois revendications structurantes : arrêt de la fermeture des lits d’hospitalisation, augmentation salariale de 300 euros nets/mois, embauche de personnel. Au plus fort du mouvement, en septembre 2019, le CIU recensait 260 services en grève, soit plus de la moitié des structures d’urgences publiques du territoire. En dialogue avec deux chercheuses en sciences sociales, deux infirmières et animatrices du collectif, Noémie Banes et Orianne Plumet reviennent sur la « crise » à l’hôpital public, sur leur expérience du mouvement et sur le travail par temps de Covid-19.
« Plus jamais ça ! » Reconstruire ensemble un futur écologique, féministe et social
Authors: Buisson Marie , Julliard Jean-François , Rivoire Julien , Delage Pauline , Gaudillière Jean-Paul , Girard Gabriel
Published: March 2021

Le 27 mars 2020, le confinement à peine installé, dix-huit responsables d’organisations environnementales, de syndicats et d’associations dont Greenpeace, la CGT et Attac rendaient publique une tribune 1 invitant à se saisir de la crise pour penser le « jour d’après » et la reconversion sociale et écologique en France et dans le monde. Cette tribune n’était que l’une des premières initiatives qui tout au long de la première vague épidémique visaient à profiter de la mise entre parenthèses du quotidien des politiques économiques néolibérales résultant de la pandémie et de l’urgence sanitaire pour faire avancer le mouvement de convergence entre réponses à la crise sociale et réponses à la crise écologique. Trois acteurs de cette coalition inédite nous parlent de cette initiative, de ses origines et du plan de sortie de crise qu’elle a élaboré.
De la théorie de la régulation aux capitalismes à l’épreuve de la pandémie
Authors: Boyer Robert , Gaudillière Jean-Paul
Published: March 2021

Robert Boyer est économiste, anciennement directeur de recherche au CNRS et directeur d’études à l’EHESS. Il est l’un des principaux animateurs de l’école dite de la régulation, laquelle a été, à partir des années 1970, l’un des principaux courants d’analyse de la diversité des capitalismes, des logiques de l’accumulation, des régulations et des dispositifs institutionnels qui les organisent. Il est l’auteur de Économie politique des capitalismes (La Découverte, 2015) et vient de publier Les capitalismes à l’épreuve de la pandémie (La Découverte, 2020). Il revient ici sur cette trajectoire individuelle et collective.
