Aim. The work demonstrates a clinical case of an extremely rare pathology ‒ hemangiomatosis with damage to the skin, subcutaneous tissue, lungs, stomach, intestinal, liver, kidneys, and spine. Results. Patient L., born in 1994 with multiple hemangiomas. No heredity was observed for vascular tumors. In childhood, several large hemangiomas had to be surgically removed. She resorted to the Amur Regional Perinatal Center about her first pregnancy. There was a high risk of hemorrhagic complications due to damage to internal organs, primarily the lungs. Since there were multiple lesions of the vertebrae, it was decided not to use neuraxial methods of anesthesia. Total intravenous anesthesia and artificial ventilation of the lungs under the control of bronchoscopy were chosen by the method of anesthesia. Hemangiomatosis with lesions of internal organs was the indication for a Cesarean section. The operation took place without complications. The child was born healthy. Conclusion. In most cases, cosmetic defects are a significant problem of hemangiomatosis. However, in a number of situations, for example during pregnancy, there is a high risk of rupture of hemangiomas and the development of bleeding. In this case, the choice of the method of delivery and anesthesia depends on the location of the hemangiomas.
Cubical homology-based Image Classification - A Comparative Study
Authors:   , Choe Seungho
Published: December 2021

Persistent homology is a powerful tool in topological data analysis (TDA) to compute, study and encode efficiently multi-scale topological features and is being increasingly used in digital image classification. The topological features represent number of connected components, cycles, and voids that describe the shape of data. Persistent homology extracts the birth and death of these topological features through a filtration process. The lifespan of these features can represented using persistent diagrams (topological signatures). Cubical homology is a more efficient method for extracting topological features from a 2D image and uses a collection of cubes to compute the homology, which fits the digital image structure of grids. In this research, we propose a cubical homology-based algorithm for extracting topological features from 2D images to generate their topological signatures. Additionally, we propose a score, which measures the significance of each of the sub-simplices in terms of persistence. Also, gray level co-occurrence matrix (GLCM) and contrast limited adapting histogram equalization (CLAHE) are used as a supplementary method for extracting features. Machine learning techniques are then employed to classify images using the topological signatures. Among the eight tested algorithms with six published image datasets with varying pixel sizes, classes, and distributions, our experiments demonstrate that cubical homology-based machine learning with deep residual network (ResNet 1D) and Light Gradient Boosting Machine (lightGBM) shows promise with the extracted topological features.
Principles for assessing the genotoxicity of carbon nanomaterials in vitro (on the example of carbon nanotubes) (literature review)

Published: December 2021

Introduction. Genotoxicity of nanomaterials (NM) is becoming a major concern when investigating new NM for their safety. Each mutagen is considered to be potentially carcinogenic, therefore a genotoxicity assessment is necessary. However, a clear strategy for assessing the genotoxic effect of NM has not yet been developed. Material and methods. The material for the analysis have included literature sources from the bibliographic databases PubMed, Scopus, RSCI. Results. Physicochemical characterization of NM is carried out using high-resolution microscopic and light scattering methods. Before testing for genotoxicity, it is necessary to know the cytotoxicity of the tested NM in order to select the appropriate concentration range. The most important and significant tests are based on the cell viability. MTT assay is a colorimetric test that evaluates the metabolic activity of cells. In addition, viability can be determined using microscopy, flow cytometry, determination of lactate dehydrogenase. Genotoxicity evaluation can be carried out only after the preliminary steps. The strategy should include genotoxicity endpoints: DNA damage, gene mutations, chromosomal damage. The in vitro mammalian gene mutation test, usually performed using mouse lymphoma cells, detects a wide range of genetic damage, including gene deletions. The most common test for detecting chromosomal damage is an in vitro micronucleus assay. DNA strand breaks are most often assessed using the comet DNA assay. Conclusion. Compulsory stages in the study of the genotoxicity of nanomaterials should be preliminary studies, including physicochemical characterization and assessment of cytotoxicity, as well as the study of the endpoints of genotoxicity and potential mechanisms.

Introduction. Air pollution with particulate matter (PM) is a serious global problem. In the Russian Federation, regular field measurements of PMs in the ambient air are carried out only in a few cities, and the data, as a rule, are not systematized. Aim of the study: long-term analysis of the data set on concentrations of fine particles in the ambient air of the city of Kazan. Material and methods. Long-term analysis of ambient air pollution by fine particles in the city of Kazan for the period from 2016 to 2020 has been carried out. To study the effect of separate factors (year, measurement time during the day, climatic conditions, the presence of other pollutants) on the levels of PM10 and PM2.5, regression analysis was applied based on the method of mixed models. To characterize the elemental composition of the PM2.5 fraction, sampling of atmospheric air on PVC filters was carried out by use of 100 NR impactor (TSI, USA). The step function and MPPD model were applied to calculate the number of particles and the mass of the deposited fraction of fine particulate matter in different regions of the human respiratory tract. Results. The PM10 concentrations remained stable over a 5-year period, while the PM2.5 concentrations decreased. At the same time, an increase in the maximum annual concentrations of both fractions was observed. The concentrations of PM10 and PM2.5 significantly depended on climatic conditions. The presence of nitrogen oxides and organic carbon in the ambient air was significantly associated with higher concentrations of PM10 and PM2.5. The elemental composition of PM2.5 fraction was represented mainly by carbon (C) (from 86.16% to 93.45%). Mathematical modeling has shown that PM10 is mainly deposited in the upper respiratory tract, and their presence in the tracheobronchial and alveolar zones is insignificant. PM2.5 particles reach the lower respiratory tract and alveolar area. Conclusion. A statistically significant upward long-term trend in the maximum annual ambient concentrations for both fractions of fine particles can increase health risks. Secondary pollutants (nitrogen oxides, organic carbon) are important factors for the formation of secondary particles in the ambient air. The results obtained indicate that when assessing the risks to public health, it is necessary not only to use the concentrations of fine particles in ambient air, but also to consider the degree of deposition of separate fractions in different parts of the human respiratory tract, considering the alleged pathogenesis and priority target cells characteristic of individual diseases.

Introduction. Professional contact with selenium, copper and their compounds, including nanoscale forms, occurs in the metallurgical processes of copper sludge processing, copper pyrite roasting, manganese, selenium and tellurium production. The wide prevalence of selenium and copper oxide nanoparticles (SeO and CuO NPs) necessitates a comparative experimental assessment of its toxicity. Materials and methods. The copper or selenium oxide nanoparticle suspensions or a deionized water were intratracheally administered to female rats at single time. The bronchoalveolar lavage fluid (BALF) was obtained 24 hours after administration. There were evaluated the cellular composition and the biochemical parameters of the BALF. Results. The changes in the cellular composition of BALF demonstrate the SeO-NP and CuO-NP have a cytotoxic effect. The BALF biochemical indices were changed to a greater extent under CuO-NP. However, the phagocytic capacity of alveolar macrophages is activated under the SeO-NP. Conclusion. The SeO-NP and CuO-NP have a cytotoxic effect. SeO-NP have a positive effect on pulmonary phagocytosis, which can presumably be associated with selenium is a biomicroelement.

Introduction. Copper plays an important role in the metabolism of the brain, but particles of copper, in the nanometer range, exhibit neurotoxic properties and cause malfunctioning of brain cells. Material and methods. For 6 weeks, 3 times a week, the animals were injected with a suspension of NPs of copper oxide. The determination of the expression of the genes GRIN1, GRIN2a, and GRIN2b, encoding the proteins GluN1, GluN2a, and GluN2b, respectively, was carried out by real-time PCR with probes. Results. A statistically significant decrease in the expression level of genes encoding NMDA receptor proteins was determined when exposed to 0.5 mg/ml CuO nanoparticles (ΔCt(GRIN1) = 0.813; ΔCt(GRIN2A) = 3.477; ΔCt(GRIN2B) = 1.37) in comparison with control group (ΔCt(GRIN1) = 6.301; ΔCt(GRIN2A) = 7.823; ΔCt(GRIN2B) = 4.747). Conclusion. Evaluation of gene expression of the NMDA receptor may be present in a genetic marker to determine the toxic effect of copper oxide nanoparticles; however, further studies are needed, including behavioral tests to confirm the clinical manifestations of neurodegenerative disorders.

House M.D. and Sherlock Holmes: An analysis of allusive intertextual elements
Authors: KUŞÇU ÖZBUDAK Seda
Published: December 2021

Intertextuality refers to the relationship among texts and can be observed both horizontally between the texts of similar genres and vertically between the texts of different genres. This relationship can be built through several literary devices, one of which is allusion. In this study, a vertical intertextual analysis was aimed at in the texts of Arthur Conan Doyle’s Sherlock Holmes stories and the world-famous TV series House, M.D. with a special focus on allusions. These elements were detected by three steps offered by Montgomery et al. (2007): notice, track, and become familiar. Then they were categorized in terms of explicit and implicit references. The results of the study point out that the House M.D. series is a highly allusive text, and it is thought that the allusions contribute to the success of this long-running series. Considering the target audience of both works, it can be thought that recognizing these allusions can be an enjoyable activity for the audience and guarantee a certain audience for the series. In this context, allusive intertextual elements can be considered not only as stylistic tools, but also as tools that provide familiarity and recognition for the alluded text.

Published: December 2021

The article is dedicated to the problem of identifying strategic groups in the business education market. The authors conducted a systematic review of publications on the topic. The object of the research is the developed markets of business education in the USA and Western Europe, the subject of the research is the groups of relatively homogeneous educational institutions that demonstrate similar strategic behaviour (strategic groups). For researchers, dividing market participants into strategic groups is the basis for identifying efficiency factors in the respective groups, and for heads of educational institutions and market regulators, it is a prerequisite for constructing meaningfully interpreted rankings and business school ratings. The purpose of the work is to identify trends in changes of the business-schools grouping approaches and the factors underlying such groupings. The authors revealed a shift of researchers' the emphasis from the characteristics of educational programs offered by schools to the positioning of schools in a wide social and educational environment. Although the strategic analysis level is growing, the discussion topic remains fragmented and covers only a part of the business education markets.
Exploring the Effects of Active Magnetic Drag in a General Circulation Model of the Ultrahot Jupiter WASP-76b
Authors: Beltz Hayley , Rauscher Emily , Roman Michael T. , Guilliat Abigail
Published: December 2021

Ultrahot Jupiters represent an exciting avenue for testing extreme physics and observing atmospheric circulation regimes not found in our solar system. Their high temperatures result in thermally ionized particles embedded in atmospheric winds interacting with the planet’s interior magnetic field by generating current and experiencing bulk Lorentz force drag. Previous treatments of magnetic drag in 3D general circulation models (GCMs) of ultrahot Jupiters have mostly been uniform drag timescales applied evenly throughout the planet, which neglects the strong spatial dependence of these magnetic effects. In this work, we apply our locally calculated active magnetic drag treatment in a GCM of the planet WASP-76b. We find the effects of this treatment to be most pronounced in the planet’s upper atmosphere, where strong differences between the day and night side circulation are present. These circulation effects alter the resulting phase curves by reducing the hot spot offset and increasing the day–night flux contrast. We compare our models to Spitzer phase curves, which imply a magnetic field of at least 3 G for the planet. We additionally contrast our results to uniform drag timescale models. This work highlights the need for more careful treatment of magnetic effects in atmospheric models of hot gas giants.
The Far-away Blues: Exploring the Furthest Extents of the Boötes I Ultra-faint Dwarf Galaxy
Authors: Filion Carrie , Wyse Rosemary F. G.
Published: December 2021

Establishing the spatial extents and the nature of the outer stellar populations of dwarf galaxies is necessary for the determination of their total masses, current dynamical states, and past evolution. We here describe our investigation of the outer stellar content of the Boötes I ultra-faint dwarf galaxy, a satellite of the the Milky Way. We identify candidate member blue horizontal branch and blue straggler stars of Boötes I, both tracers of the underlying ancient stellar population, using a combination of multiband Pan-STARRS photometry and Gaia astrometry. We find a total of twenty-four candidate blue horizontal branch member stars with apparent magnitudes and proper motions consistent with membership of Boötes I, nine of which reside at projected distances beyond the nominal King profile tidal radius derived from earlier fits to photometry. We also identify four blue straggler stars of appropriate apparent magnitude to be at the distance of Boötes I, but all four are too faint to have high-quality astrometry from Gaia. The outer blue horizontal branch stars that we have identified confirm that the spatial distribution of the stellar population of Boötes I is quite extended. The morphology on the sky of these outer envelope candidate member stars is evocative of tidal interactions, a possibility that we explore further with simple dynamical models.

We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX is to measure the redshifts of over a million Lyα emitting galaxies between 1.88 < z < 3.52, in a 540 deg2 area encompassing a comoving volume of 10.9 Gpc3. No preselection of targets is involved; instead the HETDEX measurements are accomplished via a spectroscopic survey using a suite of wide-field integral field units distributed over the focal plane of the telescope. This survey measures the Hubble expansion parameter and angular diameter distance, with a final expected accuracy of better than 1%. We detail the project’s observational strategy, reduction pipeline, source detection, and catalog generation, and present initial results for science verification in the Cosmological Evolution Survey, Extended Groth Strip, and Great Observatories Origins Deep Survey North fields. We demonstrate that our data reach the required specifications in throughput, astrometric accuracy, flux limit, and object detection, with the end products being a catalog of emission-line sources, their object classifications, and flux-calibrated spectra.
New Evidence for Wet Accretion of Inner Solar System Planetesimals from Meteorites Chelyabinsk and Benenitra

Published: December 2021

We investigated the hydrogen isotopic compositions and water contents of pyroxenes in two recent ordinary chondrite falls, namely, Chelyabinsk (2013 fall) and Benenitra (2018 fall), and compared them to three ordinary chondrite Antarctic finds, namely, Graves Nunataks GRA 06179, Larkman Nunatak LAR 12241, and Dominion Range DOM 10035. The pyroxene minerals in Benenitra and Chelyabinsk are hydrated (∼0.018–0.087 wt.% H2O) and show D-poor isotopic signatures (δDSMOW from −444‰ to −49‰). On the contrary, the ordinary chondrite finds exhibit evidence of terrestrial contamination with elevated water contents (∼0.039–0.174 wt.%) and δDSMOW values (from −199‰ to −14‰). We evaluated several small parent-body processes that are likely to alter the measured compositions in Benenitra and Chelyabinsk and inferred that water loss in S-type planetesimals is minimal during thermal metamorphism. Benenitra and Chelyabinsk hydrogen compositions reflect a mixed component of D-poor nebular hydrogen and water from the D-rich mesostases. A total of 45%–95% of water in the minerals characterized by low δDSMOW values was contributed by nebular hydrogen. S-type asteroids dominantly composed of nominally anhydrous minerals can hold 254–518 ppm of water. Addition of a nebular water component to nominally dry inner solar system bodies during accretion suggests a reduced need of volatile delivery to the terrestrial planets during late accretion.

Published: December 2021

The monotypic genus Latonius Kononova, 1982 (Platygastroidea, Scelionidae), was described from a single female specimen collected in southern Ukraine. It somewhat resembles Trissolcus Ashmead but has a distinctive claval formula. The only species in the genus, Latonius planus Kononova, 1982, is lacking any details regarding biology, sexual dimorphism, intraspecific variability, or distribution. Based on recently collected specimens the present study clarifies the position of Latonius within the Telenominae, provides a comprehensive description accompanied by high quality images, and compares Latonius and Trissolcus. Five molecular markers were amplified, and sequences of L. planus were analyzed using a data set for the molecular phylogeny of Telenominae (Taekul et al. 2014) and a molecular phylogeny of Trissolcus (Talamas et al. 2019). We dissected the metasoma, tarsi, antennae, and ovipositor and performed SEM imaging. The genera Latonius and Ioseppinella Mineo, O’Connor & Ashe, 2010, are treated as junior synonyms of Trissolcus and the type species of Latonius and Ioseppinella are considered to be conspecific (syn. nov.).

Surveys for egg-parasitoid wasps were conducted in Rafsanjan, Iran, on two species of Pentatomidae (Hemiptera) found in pistachio orchards, Acrosternum arabicum Wagner and Brachynema signatum Jakovlev. Five species of Scelionidae (Platygastroidea) were recovered, including one that is here described as new: Psix saccharicola (Mani), Trissolcus colemani (Crawford), T. darreh Talamas sp. nov., T. perepelovi (Kozlov), and T. semistriatus (Nees). In addition to describing a new species, we report new host associations, provide COI barcodes for four of these species, and discuss host-related intraspecific variation in T. darreh and T. perepelovi.
Adventive Gryon aetherium Talamas (Hymenoptera, Scelionidae) associated with eggs of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae) in the USA

Published: December 2021

Bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), has become a major pest of cole crops (cabbage, broccoli, cauliflower, kale) in California since its arrival in 2008. In this study we documented parasitism of B. hilaris eggs at a highly infested site in northern California by deploying sentinel B. hilaris eggs and collecting naturally-laid B. hilaris eggs in the soil. Two parasitoids, Gryon aetherium Talamas (Hymenoptera, Scelionidae) and Ooencyrtus californicus Girault (Hymenoptera, Encyrtidae), emerged from sentinel eggs, but only G. aetherium was documented attacking eggs in the soil. Gryon aetherium is currently being assessed as a classical biological control agent for B. hilaris in California, and mating experiments showed that crosses between G. aetherium from Pakistan and California yielded viable female offspring. This report marks the first known record of G. aetherium in the USA, and further work should be conducted to assess the potential of this parasitoid for biological control of B. hilaris.
Quel bilan social du dernier gouvernement Merkel ?
Authors: Lestrade Brigitte
Published: December 2021

La constitution du gouvernement Merkel 4, qui a mis beaucoup de temps en raison de la réticence des socio-démocrates à renouveler l’expérience d’une GroKo dominée par la CDU, a débouché sur un contrat de coalition entre les deux partenaires qui, dans le domaine social, porte clairement la marque du SPD. Les priorités retenues par le nouveau gouvernement, notamment dans le domaine du logement et des retraites, visaient essentiellement l’amélioration des conditions de vie et de travail des personnes modestes. La GroKo y est parvenue dans l’ensemble, même si ses réalisations ont été qualifiées d’insuffisantes par certains. Elle a de plus fait voter une loi sur l’immigration de travailleurs qualifiés et, in extremis, une loi sur la chaîne d’approvisionnement. La gestion des catastrophes intervenues en cours de mandat, telle que la pandémie du Covid 19 et les inondations du mois de juillet en Rhénanie-du-Nord-Westphalie et en Rhénanie-Palatinat, diversement appréciée par les électeurs, n’a pas porté atteinte à l’image d’une GroKo, dont presque personne pensait il y a quatre ans qu’elle tiendrait la distance.
Réflexions sur nos origines : vision d’hier, savoirs d’aujourd’hui
Authors: Patou-Mathis Marylène
Published: December 2021

En Occident, du xviii e au début du xx e siècle, les grands débats ont porté sur la place des humains dans la Nature, puis sur leur origine et leur évolution biologique et culturelle. Il a fallu franchir les obstacles relatifs à l’acceptation d’ancêtres – créationnisme, théorie du déluge, racialisme –, avant que les connaissances et les savoir-faire des Préhistoriques ne soient reconnus grâce aux études des fossiles humains et des vestiges archéologiques. Aujourd’hui, les grandes inventions qui jalonnent tout notre lointain passé, avec les implications économiques et culturelles qui en découlent, révèlent le caractère buissonnant et non linéaire de l’évolution humaine, la coexistence dans le passé de plusieurs espèces humaines et une mosaïque temporelle et spatiale des cultures.
Au commencement de l’analyse : le syndrome de Jonas
Authors: Renard Delphine
Published: December 2021

Dans La Bible, le Livre de Jonas raconte la descente du prophète au fond de la mer après son refus de sortir de son immobilisme pour partir, à l’appel de Dieu, convertir Ninive, la grande ville pécheresse. Métaphore du travail d’individuation selon Jung, ce récit peut nous éclairer pour aborder, dans notre clinique, les commencements d’analyse avec des patients passifs, figés dans leurs certitudes et fermés à l’altérité. Comme Jonas, ils témoignent souvent d’une loyauté infaillible à une mère dépressive et froide.

Le débat autour du « au commencement », cher aux traducteurs de la Bible, pourrait être invitation pour tout un chacun d’interpréter, de traduire et retraduire, de penser et repenser son commencement – sa fin –, de faire des récits de son histoire, sans rien pouvoir dire de cet avant, point d’ouverture, ni de cet après, point de fermeture.
La bisexualité originelle aujourd’hui
Authors: Mignet Mariette
Published: December 2021

Le choix fait ici est de réfléchir à la bisexualité originelle à partir de notre aujourd’hui et de ses manifestations dans les individus. Depuis les mythes (de la Grèce), la religion (Hindou), nous arrivons aux problématiques actuelles de tentatives de faire apparaître cette bisexualité. L'auteure s'interroge, comme Freud à son époque, à partir des données de la biologie quant à la construction sexuée. Elle s'étonne des confusions, nombreuses, à propos de la construction psychique de l’identité sexuée, ainsi que du peu de considérations pour le processus qui conduit à cette dernière au cours de la petite enfance. Vouloir changer de sexe, c’est vouloir être d’un seul sexe, celui qu’on n’a pas ; nouvelle confusion entre androgynie, hermaphroditisme et identité. Jung nous a donné des outils, avec le concept d’anima/ animus qui ouvre de telles possibilités créatrices aussi bien pour l’individu que pour la relation à l’autre.
Les origines de la conscience selon Erich Neumann
Authors: Liard Véronique
Published: December 2021

La parution en 1949 de l’ouvrage d’Erich Neumann , Origines et histoire de la conscience, est saluée par Jung qui accepte d’en écrire la préface. La première partie de l’analyse de Neumann est consacrée aux stades mythologiques du développement. Partant du mythe de création, Neumann montre comment le germe embryonnaire du moi se libère peu à peu de l’Ouroboros, la sphère parfaite qui englobe tous les contraires. La seconde partie du livre de Neumann fait correspondre à ces stades mythologiques les stades psychologiques du développement de la conscience. Aux premiers stades de l’humanité, l’individu et le groupe, le moi et l’inconscient, l’homme et le monde étaient encore soudés dans une participation mystique. Mais la conscience se libère progressivement de cette fascination. Elle devient capable de réfléchir, de comprendre, d’interpréter.
Les historiens et la mondialisation (1990-2020)
Authors: Inglebert Hervé
Published: December 2021

L’attitude des historiens face à la mondialisation a été influencée depuis 1990 par les débats sur la globalisation. Celle-ci a permis, après l’histoire universelle européocentrique des années 1870-1970 et la World History des années 1960-1990, de développer des perspectives nouvelles marquées par les méthodes de l’histoire globale. Mais les résultats sont différents selon les sphères culturelles : en France et en Italie, on a privilégié l’histoire connectée ; en Allemagne et dans le monde anglo-saxon, on a insisté sur les processus de globalisation ; en Russie et en Chine, on estime que la globalisation concerne le domaine économique mais non les dimensions politiques et culturelles locales qui restent en dehors du monde occidental. Enfin, les limites méthodologiques de l’histoire globale ont des conséquences sur les conceptions de la globalisation qu’on ne peut faire remonter trop loin dans le temps et amènent à concevoir une histoire de l’humanité qui dépasse celle de la seule mondialisation.
La globalisation de l’histoire de la philosophie et l’idée d’une phénoménologie transformative
Authors: Elberfeld Rolf , Albert Nicole G.
Published: December 2021

Depuis le début du XXI e  siècle, la globalisation est devenue un thème central dans les sciences humaines, même si la mondialisation croissante des discours dans les sciences humaines apparaît en réalité dès le XX e  siècle. Dans le domaine de la philosophie, la mondialisation du cadre thématique a été encouragée en particulier par les Congrès mondiaux de philosophie depuis 1900. Sous l’impulsion de ces évolutions, les histoires de différentes philosophies ont émergé à travers le monde et dans de nombreuses langues différentes. En outre, des ouvrages d’histoires globales de la philosophie se multiplient depuis une vingtaine d’années. Pour faire face à cette diversité thématique dans la philosophie d’aujourd’hui, l’approche d’une phénoménologie transformative est abordée à la fin de l’article.
La géographie et les espaces dominés dans la mondialisation : considérations épistémologiques Nord-Sud
Authors: Fournet-Guérin Catherine
Published: December 2021

A partir de l’étude d’un corpus de travaux de géographes en français et en anglais depuis les années 1990, l’article est consacré à la manière dont les études géographiques portant sur les espaces dits des Suds, entendus comme faisant partie des pays dominés à l’échelle mondiale, intègrent la notion de mondialisation. Le constat de la faible prise en compte des pays des Suds dans les études portant sur la mondialisation est d’abord établi. En réaction, nombre de géographes concernés ont intégré cette dimension dans leurs travaux pour montrer ce qu’était la mondialisation depuis les Suds et qu’il s’agissait d’un phénomène bien réel dont ils n’étaient pas exclus. Les travaux sont souvent orientés idéologiquement, les uns développant des approches critiques de la mondialisation, dans la filiation d’études marxistes et tiers-mondistes, les autres insistant au contraire sur les conséquences bénéfiques de la mondialisation pour les pays des Suds. La plupart convergent cependant pour considérer que la mondialisation accentue les inégalités sociales et spatiales, assertion qui est ici à la fois considérée puis soumise à discussion.
Technologies mondialisées, mondialisation technologique, Digital Globalization : quels liens entre les NTIC et la mondialisation ?
Authors: Obadia Lionel
Published: December 2021

Cet article se propose de reprendre et d’approfondir l’épineuse question des rapports entre technologies (principalement digitales, les NTIC) et mondialisation. Généralement considérés sous l’angle d’un parallélisme (les deux vont de pair) agrémenté d’une réciprocité (et s’influençant mutuellement), ces rapports sont plus souvent postulés que décrits en détail et plus encore, questionnés. L’objectif est ici moins de qualifier de manière définitive la nature de ces liens, que de souligner la richesse du champ de réflexion, et d’en tracer les contours à grands traits et de présenter quelques pistes de réflexion récentes et fécondes, autour de concepts clefs, comme la « mondialisation technologique » ou « digitale ».
Entrer dans la danse : circulation et décalage à Cuba
Authors: Boudreault-Fournier Alexandrine
Published: December 2021

Cet essai développe une analyse critique de la mondialisation basée sur des recherches de terrains entreprises dans la décennie 2010 à Cuba, plus particulièrement à La Havane. L’enseignement de la mondialisation dans les universités anglo-saxonnes au Canada et en Grande-Bretagne dans les années 2000 se caractérisait par une peur de l’homogénéisation de la culture, puis de l’application d’une approche ethnographique pour l’exploration du processus d’appropriation culturelle engendrée par les interactions entre le local et le transnational. Des recherches de terrain ont cependant montré, parfois de manière concrète, comment la vision de la mondialisation composée de systèmes de circulations fluides et sans tension était utopique et non pertinente dans le contexte cubain (et probablement dans tous les pays de l’hémisphère Sud). L’histoire du « dossier dubstep » racontée ici permet d’illustrer le sentiment de décalage tel qu’exprimé par des DJs et producteurs de musique électronique à La Havane et leur désir d’entrer dans la danse. Enfin, cet essai jette un regard critique sur une vision fluide des échanges, souvent associée au concept de circulation et, par extension, au phénomène de la mondialisation.
