NEUROANATOMY, DIGITAL ATLASES, AND TEMPLATES OF BRAINS OF DOMESTIC ANIMALS (CAT, DOG, PIG, HORSE and SHEEP) USING MAGNETIC RESONANCE IMAGING
Authors: Aydoğdu Sedat
Published: April 2024

Over the last two decades, neuroscience has witnessed an explosion in the utilization of non-invasive imaging methods (particularly MRI) that are used to investigate to study the brain. Providing accurate and detailed imaging, MRI has a significant impact on figuring out the anatomy and functioning of the brain. In recent years, researchers studying on veterinary science have seen MRI as an indispensable tool themselves. It is essential to understand the anatomy of the normal brain in order to explain many of the pathological processes. This review focused on neuroanatomical studies, atlases and templates generated from the brains of domestic animals (cat, dog, pig, horse, donkey, cattle, sheep, goat, camel) using MRI from the 1980s to the present. Its data were summarized under three main parts. Firstly, the cross-sectional anatomy of the brain created using MRI was examined. Afterward, digital atlases and templates, which have had an essential place in modern neuroimaging analysis (such as registration, segmentation and three-dimensional reconstruction) in recent years, were summarized. Finally, in vivo or ex vivo studies in which crucial white matter tracts in the brain are three-dimensionally modeled with DTI (Diffusion Tensor Imaging) in domestic mammals were reviewed. Several studies examining the neocortex by DTI were also included in the review in this section. There were also neuroanatomy studies conducted with MRI in several specific species in this review. In conclusion, this review focused on the importance of MRI in neuroimaging of the brain in domestic animals.

Authors:   Far Eastern State Transport University, Blazhevich Blazhevich
Published: April 2024

The article provides a brief description of the development of cross-border cooperation between the regions of the Russian Far East and northeast China, and examines the sociolinguistic aspects of intercultural communication. Attention is drawn to the opportunities for social mobility that become available to the population of the regions in connection with international economic cooperation, and the importance of the educational institutions for such cooperation is emphasized. It is concluded that there is a natural need for friendly communication between peoples belonging to such different cultures, and that communication between the population of border regions is quickly restored, after some decline during the Covid restrictions.

High angular resolution imaging by Atacama Large Millimeter/submillimeter Array (ALMA) has revealed the near universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence stars are still poorly sampled, despite the prevalence of M dwarfs in the Galaxy. Here we present high-resolution (∼50 mas, 8 au) ALMA Band 6 observations of six disks around mid-M stars in Taurus. We detect dust continuum emission in all six disks, 12CO in five disks, and 13CO line in two disks. The size ratios between gas and dust disks range from 1.6 to 5.1. The ratio of about 5 for 2M0436 and 2M0450 indicates efficient dust radial drift. Four disks show rings and cavities, and two disks are smooth. The cavity sizes occupy a wide range: 60 au for 2M0412, and ∼10 au for 2M0434, 2M0436, and 2M0508. Detailed visibility modeling indicates that small cavities of 1.7 and 5.7 au may hide in the two smooth disks 2M0450 and CIDA 12. We perform radiative transfer fitting of the infrared spectral energy distributions to constrain the cavity sizes, finding that micron-sized dust grains may have smaller cavities than millimeter grains. Planet–disk interactions are the preferred explanation to produce the large 60 au cavity, while other physics could be responsible for the three ∼10 au cavities under current observations and theories. Currently, disks around mid- to late M stars in Taurus show a higher detection frequency of cavities than earlier-type stars, although a more complete sample is needed to evaluate any dependence of substructure on stellar mass.
Impact of Electron Precipitation on Brown Dwarf Atmospheres and the Missing Auroral

Published: April 2024

Recent observations have demonstrated that very low-mass stars and brown dwarfs are capable of sustaining strong magnetic fields despite their cool and neutral atmospheres. These kilogauss field strengths are inferred based on strong, highly circularly polarized gigahertz radio emission, a consequence of the electron cyclotron maser instability. Crucially, these observations imply the existence of energetic nonthermal electron populations, associated with strong current systems, as are found in the auroral regions of the magnetized planets of the solar system. Intense auroral electron precipitation will lead to electron collisions with the H2 gas that should generate the ion

nondetections can be explained by electron beams of typical energies ≳2–10 keV, which penetrate deeply enough that any

Published: April 2024

We report on a study of the narrow Fe Kα line and reflection spectrum in the well-known Seyfert-2 active galactic nucleus (AGN), NGC 4388. X-ray spectra summed from two extensive NICER monitoring campaigns, separated by years, show strong evidence of variation in the direct continuum and reflected emission, but only small variations in the obscuring gas. Fits to the spectra from individual NICER observations find a strong, positive correlation between the power-law photon index, Γ, and direct flux that is commonly observed in unobscured AGN. A search for a reverberation lag between the direct and reflected spectra—dominated by the narrow Fe Kα emission line—measures a timescale of

Determination of fundamental parameters of stars impacts all fields of astrophysics, from galaxy evolution to constraining the internal structure of exoplanets. This paper presents a detailed spectroscopic analysis of Barnard’s star (otherwise known as Gl 699) that compares an exceptionally high-quality (an average signal-to-noise ratio of ∼1000 in the entire domain), high-resolution near-infrared (NIR) spectrum taken with Canada-France-Hawaii Telescope/SPIRou to PHOENIX-ACES stellar atmosphere models. The observed spectrum shows thousands of lines not identified in the models with a similarly large number of lines present in the model but not in the observed data. We also identify several other caveats, such as continuum mismatch, unresolved contamination, and spectral lines significantly shifted from their expected wavelengths; all of these can be a source of bias for the determination of abundance. Out of >104 observed lines in the NIR that could be used for chemical spectroscopy, we identify a short list of a few hundred lines that are reliable. We present a novel method for determining the effective temperature (T
eff) and overall metallicity of slowly rotating M dwarfs that uses several groups of lines as opposed to bulk spectral fitting methods. With this method, we infer T
eff = 3231 ± 21 K for Barnard's star, consistent with the value of 3238 ± 11 K inferred from the interferometric method. We also provide measurements of the abundance of 15 different elements for Barnard's star, including the abundances of four elements (K, O, Y, Th) never reported before for this star. This work emphasizes the need to improve current atmosphere models to fully exploit the NIR domain for chemical spectroscopy analysis.

To investigate the effects of stellar feedback on the gravitational state of giant molecular clouds (GMCs), we study 12CO and 13CO Atacama Large Millimeter/submillimeter Array maps of nine GMCs distributed throughout the Large Magellanic Cloud (LMC), the nearest star-forming galaxy to our own. We perform noise and resolution matching on the sample, working at a common resolution of 3.″5 (0.85 pc at the LMC distance of 50 kpc), and we use the Spectral Clustering for Molecular Emission Segmentation clustering algorithm to identify discrete substructure, or “clumps.” We supplement these data with three tracers of recent star formation: 8 μm surface brightness, continuum-subtracted Hα flux, and interstellar radiation field energy density inferred from dust emission. The 12CO clumps identified cover a range of 3.6 dex in luminosity-based mass and 2.4 dex in average 8 μm surface brightness, representative of the wide range of conditions of the interstellar medium in the LMC. Our observations suggest evidence for increased turbulence in these clouds. While the turbulent linewidths are correlated with clump surface density, in agreement with previous observations, we find even better correlation with the three star formation activity tracers considered, suggesting stellar energy injection plays a significant role in the dynamical state of the clumps. The excess linewidths we measure do not appear to result from opacity broadening. 12CO clumps are found to be typically less gravitationally bound than 13CO clumps, with some evidence of the kinetic-to-gravitational potential energy ratio increasing with star formation tracers. Further multiline analysis may better constrain the assumptions made in these calculations.

Galactic cosmic rays (GCRs) are charged particles that reach the heliosphere almost isotropically in a wide energy range. In the inner heliosphere, the GCR flux is modulated by solar activity so that only energetic GCRs reach the lower layers of the solar atmosphere. In this work, we propose that high-energy GCRs can be used to explore the solar magnetic fields at low coronal altitudes. We used GCR data collected by the High-Altitude Water Cherenkov observatory to construct maps of GCR flux coming from the Sun’s sky direction and studied the observed GCR deficit, known as Sun shadow (SS), over a 6 yr period (2016–2021) with a time cadence of 27.3 days. We confirm that the SS is correlated with sunspot number, but we focus on the relationship between the photospheric solar magnetic field measured at different heliolatitudes and the relative GCR deficit at different energies. We found a linear relationship between the relative deficit of GCRs represented by the depth of the SS and the solar magnetic field. This relationship is evident in the observed energy range of 2.5–226 TeV, but is strongest in the range of 12.4 33.4 TeV, which implies that this is the best energy range to study the evolution of magnetic fields in the low solar atmosphere.
Probing the Stellar Populations and Star Formation History of Early-type Galaxies at 0 < z < 1.1 in the Rest-frame Ultraviolet

Published: April 2024

We measure the evolution of the rest-frame near-ultraviolet (NUV)−V colors for early-type galaxies in clusters at 0 < z < 1.1 using data from the Hyper Suprime-Cam Subaru Strategic Program, CFHT Large Area U-band Deep Survey, and local Sloan Digital Sky Survey clusters observed with Galaxy Evolution Explorer. Our results show that there is an excess in the ultraviolet spectrum in most quiescent galaxies (compared to the expectations from models fitting their optical/infrared colors and spectra) below z ∼ 0.6, beyond which the excess UV emission fades rapidly. This evolution of the UV color is only consistent with the presence of a highly evolved, hot horizontal branch subpopulation in these galaxies (among the majority of cool and optically bright stars), comprising on average 10% of the total stellar mass and forming at z > 3. The blue UV colors of early-type galaxies at low–intermediate redshifts are likely driven by this subpopulation being enriched in helium up to ∼44%. At z > 0.8 (when the extra UV component has not yet appeared) the data allow us to constrain the star formation histories of galaxies by fitting models to the evolution of their UV colors: we find that the epoch at which the stellar populations formed lies in the range 3 < z
form < 10 (corresponding to 0.5–2.2 Gyr after the Big Bang) with a star formation e-folding timescale of τ = 0.35–0.7 Gyr, suggesting that these galaxies formed the majority of stars at very high redshift, with a brief yet intense burst of star formation activity. The star formation history and chemical evolution of early-type galaxies resemble those of globular clusters, albeit on much larger scales.
A New Dissociative Galaxy Cluster Merger: RM J150822.0+575515.2

Published: April 2024

Galaxy cluster mergers that exhibit clear dissociation between their dark matter, intracluster gas, and stellar components are great laboratories for probing dark matter properties. Mergers that are binary and in the plane of the sky have the additional advantage of being simpler to model, allowing for a better understanding of the merger dynamics. We report the discovery of a galaxy cluster merger with all these characteristics and present a multiwavelength analysis of the system, which was found via a search in the redMaPPer optical cluster catalog. We perform a galaxy redshift survey to confirm the two subclusters are at the same redshift (0.541, with 368 ± 519 km s−1 line-of-sight velocity difference between them). The X-ray morphology shows two surface brightness peaks between the brightest cluster galaxies (BCGs). We construct weak-lensing mass maps that reveal a mass peak associated with each subcluster. Fitting Navarro–Frenk–White profiles to the lensing data, we find masses of M

Using the observed merger parameters, we find analog systems in cosmological n-body simulations and infer that this system is observed between 96 and 236 Myr after pericenter, with the merger axis within 28° of the plane of the sky.
Occurrence dataset of campus birds in Nanjing, Jiangsu Province, China

Published: April 2024

The protection of urban biodiversity plays a critical role in maintaining urban ecological security. As a unique taxon of urban wildlife, birds have been intensively used as an indicator of our surrounding environment. Although the diversity of urban bird species has received increasing attention, present studies are mainly focused on urban parks. As one of the important components of the urban ecosystem, the university campus also plays a critical role in maintaining bird diversity. Due to the lack of observation data, it is a challenge to evaluate the impact of the environmental conditions on campus bird diversity. Given the most concentrated higher education resources in China, Nanjing has a large number of universities, covering a wide area of the urban landscape. The landscape of these universities usually has a high percentage of green space as well as water bodies, which is conducive to attracting various bird species to inhabit. Here, we conducted a one-year bird survey from January 2019 to December 2019 in 12 universities in Nanjing and provided an occurrence dataset containing detailed species and geographical information, providing a good source to study the ecological and anthropogenic factors on urban bird diversity on a local and larger scale.

This dataset represents the first annual record of birds publicly released by 12 universities in Nanjing, Jiangsu Province. It includes classification information, population, distribution, and survey details. All data has been published on GBIF.

Published: April 2024

Morphological and genetic variation among populations of the widespread buthid scorpion, Hottentotta saulcyi (Simon, 1880), occurring in western and southwestern Iran was explored using morphometric variables, one nuclear marker (28S rDNA) and three mitochondrial markers (12S rDNA, 16S rDNA, and Cytochrome c Oxidase Subunit I). Genetic and morphometric statistical analyses revealed extensive cryptic diversity. Phylogenetic analysis with Bayesian Inference and Maximum Likelihood uncovered two divergent clades, one of which is described as a new species, Hottentotta hatamtiorumsp. nov., from Ilam and Khuzestan Provinces, southwestern Iran. The description of the new species raises the total count of Hottentotta Birula, 1908 species to 61, twelve of which are endemic or subendemic to the Iranian Plateau.
Lionfish (Pterois miles) in the Mediterranean Sea: a review of the available knowledge with an update on the invasion front
Authors: Bottacini Davide , Pollux Bart J. A. , Nijland Reindert , Jansen Patrick A. , Naguib Marc , Kotrschal Alexander
Published: April 2024

Invasive species often severely impact ecosystems and human activities in the areas that they invade. The lionfishes Pterois miles and P. volitans are regarded as the most successful invasive fishes in marine ecosystems. In the last 40 years, these Indo-Pacific predators have established in the tropical western Atlantic Ocean, with well-documented detrimental effects on the local fish communities. Around 10 years ago, a second invasion began in the Mediterranean Sea, which is being colonised by P. miles. Given the invasive potential of P. miles and the fact that the ecology and biodiversity of the temperate/sub-tropical Mediterranean Sea offer a different setting from the tropical western Atlantic, specific knowledge on this second invasion is needed. Here, we: (i) review the scientific knowledge available on the ecology of invasive lionfishes, (ii) discuss such knowledge in the context of invasion ecology and (iii) suggest future research avenues on the P. miles invasion in the Mediterranean Sea. In addition, we offer an update on the spread of P. miles in the Mediterranean Sea. While the history and development of the Mediterranean invasion are resolved and some mitigation plans have been implemented locally, the study of the interactions of P. miles with Mediterranean species and their impact on the local biodiversity is in its infancy. Closing this gap will lead to important fundamental insights in invasion ecology and will result in predictions on the impact of P. miles on the ecology and ecosystem services of the Mediterranean Sea. Such information will have practical implications for policy-makers aiming to devise sound and efficient mitigation plans.
La mystérieuse puissance de la vie

Published: April 2024

Le présent article examine l’œuvre de Sándor Ferenczi en mettant en relation ses conceptions psychanalytiques et les questions éducatives qui, bien que sous-jacentes, constituent une trame omniprésente dans son œuvre. Son attention aiguë à l’imbrication des dynamiques intrapsychiques, des relations intersubjectives et des influences environnementales conduit Ferenczi à une lecture du traumatisme comme résultat d’un processus relationnel dysfonctionnel dans lequel la dimension contextuelle joue un rôle fondamental dès les premières étapes de la vie du nouveau-né. Sa sensibilité est à la base d’une recherche sur la technique psychanalytique qui introduit dans la relation de soin des modalités créatives qui, avant et au-delà de la parole, interrogent le contre-transfert de l’analyste et ses résonances vécues au contact du noyau irreprésentable du traumatisme du patient. Ses théories gardent aujourd’hui encore une résonance prégnante dans la formation des professionnels de l’éducation et du soin, les appelant à réfléchir sur leurs propres dynamiques affectives et sur les formes de ressenti qui orientent leur relation à la souffrance de ceux qui ont vécu des expériences « limites ». Comment s’en inspirer pour développer l’apprentissage par l’expérience dans un contexte universitaire ? Comment aider les éducateurs en formation à faire l’expérience d’un apprentissage insaturé, alimenté par un cadre éthico-esthétique, ouvert aux langages de l’art et de la poésie, visant à développer et à affiner leur sensibilité et leur empathie ?

Cependant, nous démontrerons que les principes d’hospitalité, d’empathie et de santé du soigneur, en particulier après le « tournant de 1928 » qu’il a opéré dans le champ de la psychanalyse, sont devenus des repères non seulement pour la pratique clinique, mais également pour aiguiller l’éthique des pratiques éducatives, en évitant le potentiel traumatique présent dans tout acte qui vise à transmettre un savoir.
MRI-based model for accurate prediction of P53 gene status in gliomas
Authors: Zhao Yulin , Liang Fengning , Cao Yaru , Zhao Teng , Wang Lin , Xu Jinhui , Zhu Hong
Published: April 2024

The accurate diagnosis and treatment of gliomas depends largely on the understanding of the P53 gene status. In our study, we presented a robust deep learning model, CTD-RegNet (improved RegNet integrating CNN, vision transformer, and truth discovery), tailored for predicting P53 gene status in gliomas. Our model addressed common challenges of existing deep learning models, such as incomplete feature extraction and uncertainty. First, the model used the RegNet network as a basis for predicting P53 gene mutations by skillfully extracting heterogeneous features. Next, the RegNet network was enhanced by integrating the CNN and ViT modules to optimise feature extraction and computational efficiency. Finally, using the truth discovery algorithm, we iteratively refined model uncertainties, thereby improving prediction accuracy. Our experiments demonstrated the effectiveness of the CTD-RegNet model, achieving an impressive accuracy of 95.57% and an AUC score of 0.9789, outperforming existing P53 gene status prediction models. The non-invasive nature of our model minimised the economic burden and physical and psychological stress on patients, while providing critical insights for accurate clinical diagnosis and treatment of gliomas.
Weak convergence of the conditional single index $ U $-statistics for locally stationary functional time series
Authors: Bouzebda Salim
Published: April 2024

In recent years, there has been a notable shift in focus towards the analysis of non-stationary time series, driven largely by the complexities associated with delineating significant asymptotic behaviors inherent to such processes. The genesis of the theory of locally stationary processes arises from the quest for asymptotic inference grounded in nonparametric statistics. This paper endeavors to formulate a comprehensive framework for conducting inference within the realm of locally stationary functional time series by harnessing the conditional $ U $-statistics methodology as propounded by W. Stute in 1991. The proposed methodology extends the Nadaraya-Watson regression function estimations. Within this context, a novel estimator was introduced for the single index conditional $ U $-statistics operator, adept at accommodating the non-stationary attributes inherent to the data-generating process. The primary objective of this paper was to establish the weak convergence of conditional $ U $-processes within the domain of locally stationary functional mixing data. Specifically, the investigation delved into scenarios of weak convergence involving functional explanatory variables, considering both bounded and unbounded sets of functions while adhering to specific moment requirements. The derived findings emanate from broad structural specifications applicable to the class of functions and models under scrutiny. The theoretical insights expounded in this study constitute pivotal tools for advancing the domain of functional data analysis.
Narrative interventions: Power sharing and boundary crossing in action
Authors: Jordan Esther Skelley , Stewart Linda S.
Published: April 2024

This article reflects on the assumptions we make in the design of faculty and graduate student orientations and on the implementation of redesigned orientations that foreground participant narrative. When educational developers purposefully make space for participant stories at their orientations, it is a way not only to share power with graduate students and faculty but also to create a more inclusive environment and sense of belonging. We offer a reflection on educational developer and participant experiences of small narrative interventions in graduate student and faculty orientations at our university in 2021. We find that through foregrounding story sharing we were able to shift from assimilation to acculturation by including, cultivating, and honoring diverse views, creating community, and promoting agency.

Ao lidar com as convulsões políticas do passado de Angola, a obra literária mais tardia do antropólogo Ruy Duarte de Carvalho (1941-2010), angolano de origem portuguesa, proporciona refletir sobre a revolução dos cravos em Portugal. Não é tanto o seu desencanto retrospetivo com revoluções, mas as maneiras como provoca o pensamento, o amplifica, o liberta de amarras ou constrangimentos da simplicidade de olhar para um qualquer “nós” sem ver outros. Quer seja através da crónica ou da ficção histórica, a sua perspetiva histórica e política enriquece a antropologia – leva a olhar para a revolução dos cravos como um princípio e não um fim. Neste ensaio, enquadro excertos das suas obras, para partilhar estes estímulos.
Portugueses retornados: memória, cidadania e identidade (pós-)imperial
Authors: Peralta Elsa , Góis Bruno
Published: April 2024

Com o fim do império colonial, na sequência da Revolução do 25 de Abril de 1974, as fronteiras e a identidade da nação portuguesa são redefinidas. Neste contexto, foram repatriados das ex-colónias para Portugal cerca de meio milhão de cidadãos portugueses. A sua chegada a Portugal coloca questões importantes à identidade e à memória coletiva nacionais. Através de uma análise multidimensional da memória, a qual permite revelar a complexidade da produção e da reprodução memorial, este artigo aborda questões de cidadania e de identidade (pós-)imperiais relacionadas com os portugueses retornados. O texto destaca a fricção identitária resultante da não integração do retorno na memória coletiva nacional. A presença recente destes portugueses em África e a necessidade do seu retorno após o fim do império em 1975 questionam a narrativa do país dos Descobrimentos e dos “heróis do mar”, desafiando a ideia de uma história imperial sem conflitos coloniais e raciais.
A revolução no campo: revisitação de um conflito socioambiental no pós-25 de Abril numa aldeia da Beira Baixa
Authors: Silva Pedro Gabriel
Published: April 2024

Na sequência da revolução de 25 de Abril de 1974, uma aldeia do concelho de Belmonte foi palco, durante seis anos, de um conflito que opôs um grupo de proprietários minifundiários e parte da comunidade a uma empresa mineira. Neste artigo, resultado de um estudo histórico-antropológico apoiado em trabalho etnográfico e pesquisa em arquivos, revisita-se esse conflito socioambiental, percorrendo o processo de mobilização coletiva local e as interações entre os atores locais e externos. Os motivos que impulsionaram a mobilização coletiva contra a mineração são examinados no enquadramento da transformação política estrutural do pós-25 de Abril. Na análise é equacionado o papel que a experiência e memória da destruição ambiental passada tiveram, sobretudo, na produção de repertórios e vocabulários de protesto. Observar o conflito da aldeia Gaia através da revolução permite olhar para o processo revolucionário a partir de uma escala microssociológica, mostrando os processos de transformação política do pós-25 de Abril e o papel da participação popular na democratização do país, assim como as disputas institucionais pelo controlo do Estado e as lutas em torno da implementação de diferentes modelos e políticas de desenvolvimento.
Etnografia retrospectiva 2.0: o gesto artístico na revolução
Authors: Vespeira de Almeida Sónia
Published: April 2024

Este artigo interroga as práticas artísticas na revolução no quadro das Campanhas de Dinamização Cultural e Acção Cívica do MFA (1974-1975). Parte da revisitação de um corpus de dados recolhidos no âmbito de uma investigação publicada em 2009 (Almeida 2009), assumindo a potencialidade da segunda vida dos registos etnográficos (Leopold 2008; Almeida e Cachado 2016, 2019), perspectivados agora à luz do quadro teórico e analítico da antropologia da arte. Pretendo, deste modo, interrogar como os artistas se propuseram intervir no real no âmbito desta iniciativa e como a sua prática artística se configurou como um dispositivo para a acção, identificando-se neste período a emergência de um vocabulário artístico e estético que se aproxima daquilo que hoje é categorizado como dialógico colaborativo, participativo, comunitário ou socialmente comprometido (Bourriaud 2006 [1998]; Crehan 2011; Flynn 2018; Sansi 2015; Kester in Garrido Castellano e Raposo 2019).
Arno Brignon, Us : Galerie du Château d’Eau, Toulouse, du 25 janvier au 14 avril 2024
Authors: Adrien Muriel
Published: April 2024

L’exposition d’Arno Brignon présente ses photographies à l’occasion de trois voyages effectués avec sa famille à travers les Etats-Unis de 2018 à 2022. L’impulsion initiale de ces voyages a été double : Arno Brignon souhaitait aller voir l’Amérique de Trump, présage éventuel de ce qui nous attendait en Europe, et puis aussi partir en quête des traces d’un père autrefois très absent en raison de déplacements aux Etats-Unis. Au fil du temps, la raison d’être et le propos de ses voyages se sont transformés : il a fini par aborder le pays non plus tant en cherchant à le comprendre ou à le conquérir photographiquement, comme tant d’autres s’y étaient essayé auparavant, que d’y incorporer une veine intime, moyen pour lui de se démarquer de ses prédécesseurs et d’y apposer sa marque toute personnelle. Cette voie, il l’a trouvée en transmuant, comme à son habitude, les contraintes imposées par les circonstances en atouts et bonheurs photographiques.
An Interview with Debra Bricker Balken and Lynn Gumpert, curators of Americans in Paris: Artists Working in Postwar France, 1946-1962 (Grey Art Gallery, 2024)—Part Two
Authors: Cox Lara
Published: April 2024

The exhibition Americans in Paris: Artists Working in Postwar France, 1946-1962, running between March and July 2024, examines the art of US expats in Paris following World War II. The following is the second of a two-part interview with the show’s curators, Debra Bricker Balken and Lynn Gumpert. In this second part, the curators discuss the title of their show, which constitutes a reference to Vincente Minnelli’s famous film An American in Paris (1951, starring Gene Kelly and Leslie Caron). Their choice to pluralize “American” reveals much about their conceptual approach. They also discuss the inter-influence but also tensions between French and US artists of the post-war period. They evoke the idea of dialogue between New York and Paris, a notion that has been eclipsed by assumptions about the ascendancy of the New York art scene over the Parisian counterpart in the postwar period (for example, Guilbaut 1983). The curators turn us towards the idea of other forms of globalism, and other forms of modernism, that do not center the New York school. The interview concludes with a brief connection of this exhibit to the “post-global” moment in curatorial world (O’Neill 2019) and the wider society.
Par la fenêtre ou par la porte

Published: April 2024

De 2019 à 2022, deux procès condamnent la direction de France Télécom-Orange et son P.-D.G. Didier Lombard pour « harcèlement moral institutionnel ». C’est une première en France, une victoire acquise par de longues luttes conduites par l’Intersyndicale après que le P.-D.G. ait organisé le « départ volontaire » de 22 000 salariés en les poussant Par la fenêtre ou par la porte à quitter l’entreprise. Les auteurs du film expliquent ici comment ils ont réalisé ce documentaire, quels objectifs ils ont poursuivis et quels dispositifs cinématographiques ils ont utilisés pour le rendre attractif afin qu’il soit vu par un large public. En creux, ce documentaire interroge les pratiques syndicales et les nouvelles voies à découvrir.
Déployer l’Ésat hors des murs suffit-il à déségréguer les travailleur·euse·s handicapé·e·s ?
Authors: Jaffrès Fanny
Published: April 2024

La convention des Nations unies relatives aux droits des personnes handicapées (CDPH) de 2006 et ratifiée par la France en 2010 promeut le droit à l’inclusion en milieu ordinaire. En matière d’emploi et de travail, l’article 27 de cette convention défend le droit au travail des personnes handicapées sur la base de l’égalité avec les autres et la mise en œuvre de mesures appropriées pour répondre à leurs besoins spécifiques. Les établissements et services d’accompagnement par le travail (Ésat), comme l’ensemble des institutions spécialisées, se trouvent associés à une forme de ségrégation des personnes handicapées et sont donc remis en question. Pour répondre à l’objectif d’inclusion, les Ésat tendent alors à développer la mise à disposition en milieu ordinaire qui permet à des travailleur·se·s handicapé·es d’exercer une activité professionnelle chez un·e employeur·e ordinaire tout en restant rattaché·es à leur Ésat. Basé sur une recherche doctorale en sociologie conduite entre 2017 et 2021, cet article entend analyser ce dispositif en se demandant dans quelle mesure il permet de répondre à l’objectif d’inclusion auquel il prétend.
Les concierges d’origine portugaise à Paris : niche ethnique et travail genré
Authors: Vidal Dominique
Published: April 2024

À partir du cas des concierges d’origine portugaise à Paris, cet article se propose de contribuer aux débats sur les rapports complexes entre ethnicité et travail dans les processus de ségrégation professionnelle. Il aborde, dans un premier temps, les facteurs qui ont fait qu’en quelques décennies les concierges d’origine portugaise sont devenu·es majoritaires à Paris, avant de s’intéresser à ce que cette prédominance révèle sur la société française et les populations issues des migrations internationales. Il montre ensuite que les concierges d’origine portugaise forment une population caractérisée par des différences, parmi lesquelles le genre constitue une dimension essentielle pour rendre compte de l’expérience au travail.
Rétrospective et Perspectives de la sociologie du travail en Éthiopie
Authors: Perrin-Joly Constance
Published: April 2024

Le travail n’est pas un sujet central de la recherche en Éthiopie alors que le pays est traversé par d’importants changements dans le monde professionnel. Cet article s’attache à décrire l’organisation de la recherche éthiopienne pour comprendre le caractère restreint de la production en sociologie du travail. La recherche reste structurée sous l’angle du développement. L’article propose trois perspectives dans lesquels d’importants travaux émergent ou méritent d’être redécouverts : une sociohistoire des premiers établissements industriels, des ouvriers et de leurs mobilisations ; une analyse des parcours et de l’expérience des salarié·es dans les nouvelles industries ; un regard sur le rapport au travail et les segmentations qui le traversent, en particulier sous l’angle du genre.
Delineating “Identity” in Politics: Conflicting Definitions and Contexts
Authors: Orazi Françoise
Published: April 2024

Identity has become a core notion of UK political discourse. Despite its widespread use, its meaning is not clearly circumscribed and varies according to the discursive context. The article focuses on identity’s frequent contexts of usage. In the general media identity is heavily connoted while the meaning that is ascribed to it fluctuates according to the left-wing/right-wing-orientation of the source. In social and political science, identity has been contested as a valid category. Finally, the article traces the emergence of identity as a critical notion in the recent developments of political theory.
Responding to Identity Politics: Thinking beyond the cultural divide
Authors: Bell Emma
Published: April 2024

It is commonly argued that divides based on value-based identity politics are now the defining characteristic of the contemporary era, capable of explaining everything from the rise of Donald Trump to Brexit. Both the Conservative and Labour parties have sought to appeal to values over policy in an attempt to appeal to ‘identity conservative’ voters in marginal seats. Yet they have also recognised the need to address the grievances underpinning these attitudes, notably regional economic inequality and over-centralisation. This article seeks to critically assess whether the Conservatives’ ‘levelling up’ agenda1 and Labour’s plans to address economic inequality and devolve power downwards, as outlined in the recent Labour report by former Prime Minister Gordon Brown2, are capable of providing the recognition to voters from ‘left behind’ areas that is thought to be the principal driver of regressive identity politics. It then discusses the capacity of alternative locally-based projects that seek to address economic decline – such as community wealth building – to restore that sense of recognition and to foster a positive form of identity politics that might overcome division.
Playing the Identity Card: from Brexit to Culture Wars
Authors: Tournier-Sol Karine
Published: April 2024

Recent academic and media interest has focused on the emergence of identity-based politics in the British political landscape, with the identity divide appearing as a new structuring factor, as blatantly exposed by the Brexit referendum. This article focuses on the ability, and the growing propensity, of British right-wing political parties to play the identity card, to press this very button and activate identity conflict as a mobilizing factor, by opposing groups on grounds of social and cultural values, such as national identity and immigration, beyond traditional dividing lines such as economic redistribution. The aim is to explore how identity has been repeatedly mobilized by the right in recent years for electoral purposes, and with what effects. This begins with the UK Independence Party’s success in activating the identity divide and mobilizing identity conflicts in the years before the referendum. The second section focuses on how this mobilization of identity extended to the mainstream right and how the Conservative party reclaimed the identity card following the referendum, as the identity divide reshaped British politics and restructured party competition and the political parties' electorates. Finally, the third section explores how part of the right has been deliberately stimulating “a culture war” narrative in an attempt to maintain the identity divide holding together the Conservative 2019 electoral coalition of socially conservative voters. This raises the question of the potential impact of such a polarizing strategy, not only on the electorate and on wider social cohesion, but also on the Conservative party itself.
Dialling Down Hatred: An Online Pilot Project to Test Counter-Narrative Effectiveness Among Far-Right Sympathetic Audiences in the UK
Authors: Allchorn William
Published: April 2024

Over the past eight years, traditionalist communitarian versus more liberal cosmopolitan value divides have opened and caused considerable polarization in the UK. Cleaving to Pro-Leave and Pro-Remain positions on the EU referendum question (and though posited to have waned slightly now Brexit is settled), this new identity politics has had the lasting effect of emboldening and mainstreaming radical right-wing tenets (namely, anti-migrant, anti-Islam and anti-multicultural) that were once fringe. Despite this renewed challenge and imperative from far-right extremist organizations and their concomitant attempts at inserting their viewpoints into the UK political mainstream, there is a dearth of empirical data on what works and what does not to alleviate this divide. Indeed, most evaluations on this topic tend to privilege either an ideologically agnostic approach (i.e. treating specific extremisms as functionally equivalent or co-equal), or one specifically tailored to Islamist extremism. Moreover, approaches tend to privilege individuals who have already moved a fair way down the conveyor belt of extremism, showing either commitment to a specific extremist ideology or group of organized extremist actors. This article aims to provide a useful counterpoint to these prevailing tendencies. Taking the UK as a case study, it lays out how an iterative, experimental research methodology – mixing focus groups and surveys - can be used to test counter-messaging content and, most importantly, evaluate impactful attitudinal change among far-right sympathetic audiences. It is based on over 12 months of research among far-right sympathetic users on Facebook – with an initial round of focus group testing in September 2020 followed by larger-scale online testing on the Facebook platform from February-September 2021, and involved a collaboration between CARR, ACS, M&C Saatchi, the Outsiders & Facebook, with over 36 focus group participants and a combined online experimental reach of over 1 million Facebook users.
Remoaners, 2019 Conservative Voters and Kippers – Caricaturing political identities tied to Brexit on Reddit
Authors: Sigoillot Nicolas
Published: April 2024

This study investigates the dynamics of political discourse and the perception of political caricatures within online communities hosted on Reddit.com, focusing on the subreddit r/PoliticalCompassMemes and its engagement with Brexit-related content. Drawing from social psychology and previous research on online interactions, the roles of various structural processes in shaping the cultural habits within these communities and how they shape political caricatures of Brexit identities are going to be examined. The political relevance of these caricatures is further explored via a comparison between field observations and surveys conducted within the communities.
