The climatic and geographical conditions of Russia’s northeastern region form certain biological adaptation mechanisms in the population, contributing to the body’s optimal functioning in this environment. In spite of the fact that the body’s adaptation mechanisms to extreme conditions of Northeast Russia have been sufficiently studied, this issue remains relevant. The influence of negative factors during adolescence, when the body is extremely vulnerable, can disrupt the adaptation mechanisms and initiate pre-pathological and pathological processes. The function of the cardiovascular system is one of the main indicators that can be used to evaluate the body’s adaptive mechanisms. Therefore, the purpose of this research was to study heart rhythm regulation mechanisms in adolescents (Russians and Yakuts) permanently living in Northeast Russia. Materials and methods. Heart rate variability (HRV) parameters were evaluated in adolescents (native Yakuts and second-generation Russian newcomers to Yakutsk) aged 14–15 years (mean age 14.34 ± 0.17 years) studying at the secondary schools of Yakutsk. Results. We found an increase in the share of the very low frequency spectrum in the total HRV spectrum in Russian girls and boys (48.8 and 47.5 %, respectively) and in Yakut boys (47.9 %), which indicates an increased activity of neurohumoral regulation of metabolic processes in adolescents due to the extreme climatic and geographical conditions. Moreover, some ethnic features of heart rate regulation were identified. Unlike their Russian peers, Yakut adolescents showed statistically significant sex-related differences in HRV (p < 0.01): in boys the autonomic balance is shifted towards the sympathetic division, the power of the highfrequency spectrum is decreased, and the stress index is increased. HRV spectral power parameters in the remaining groups correspond to the average age norm and indicate a favourable course of adaptation processes with a high level of the body’s mobilization and restorative potential.

In modern experimental oncology, 3D cell cultures have become particularly important, as they provide more relevant results compared to traditional 2D cultures. The problem of obtaining relevant cell models remains urgent for the study of breast cancer. One of the most common techniques for obtaining a 3D culture is the hanging drop method. Researchers are constantly developing its modifications to reduce variations in the shape and size of the resulting cell spheroids. One of the ways to solve this problem is to apply a hydrophobic coating to the surface of cell culture plastics. Silicones or Parafilm® laboratory films are often used for this purpose. As a result, the curvature of the drop surface increases, which leads to accelerated aggregation of cells in the centre of the drop. The purpose of this research was to evaluate the possibility of applying a coating made of the silicone elastomer SIEL 159-330 (Russia) to modify the hanging drop method. Materials and methods. We used the SIEL 159-330 coating cured at a temperature lower than that recommended by the manufacturer and investigated its cytotoxic properties as well as its effect on the formation of cell spheroids in a hanging drop. The material for the study was the BT-474 breast cancer cell line. Results. The research found that the tested elastomer has no effect on cell viability. At the same time, SIEL 159-330, compared to polystyrene, significantly reduces the time of cell aggregate formation in the lower part of the drop. In addition, cell spheroids of the breast cancer culture obtained on the SIEL 159-330 coating vary less in shape and size than spheroids obtained on the polystyrene or Parafilm coating.

Modern diagnosis of various forms of malignant brain tumours (gliomas) is primarily carried out by imaging methods, such as magnetic resonance imaging, electroencephalography, and positron emission tomography; brain biopsy is also used. The disadvantages of these methods are their inaccuracy and invasiveness, which entails certain risks for the patient’s health. Therefore, finding more reliable and safe methods for diagnosing gliomas, including their biomarkers in the blood and cerebrospinal fluid, is an urgent task. This review aimed to collect data on potential biomarkers of malignant brain tumours in body fluids, in particular, cerebrospinal fluid and blood, discovered so far and having diagnostic value. The information was searched for in the following databases: UpToDate, eLibrary, PubMed, Medline, and Scopus, as well as in the search engines Google Scholar and Web of Science. Materials from the website of the World Health Organization were also used. The review mainly included articles written over the past 5 years. We found information on such biomarkers as miRNA-15b and miRNA-125b, proline, YKL-40 glycoprotein, circDNA (circular DNA) and circRNA (circular RNA), extracellular vesicles, fatty acids, and fatty acid synthases. The authors conclude that the following biomarkers: YKL-40, circDNA, circRNA, and extracellular vesicles have a large evidence base and can already be used in clinical practice. Other biomarkers require more detailed and extensive studies.

This paper dwells on the histological structure and karyometric parameters of the adrenal medulla of non-pregnant maral does throughout the year. It was found that in autumn the synthetic activity of norepinephrine-producing cells in non-pregnant maral does is the lowest in relation to other seasons of the year. Having compared our results with the literature data, we identified sex-related differences in the activity of glandular cells of the adrenal medulla, which indicates different mechanisms of metabolic regulation in bucks and does during spring (period of active horn growth in bucks) and different levels of stress in autumn (period of sexual reproduction).

Anatectic Granitic Pegmatites from the Eastern Alps: A Case of Variable Rare Metal Enrichment During High-Grade Regional Metamorphism. III: Fluid Inclusions as Potential Indicators for Anatectic Pegmatite Parent Melt Formation
Authors: Krenn Kurt , Konzett Jürgen , Stalder Roland
Published: February 2022

Fluid inclusions trapped in quartz, beryl, and cassiterite from a granitic pegmatite of the Austroalpine basement of the Eastern Alps in Northern Italy were analyzed using a cooling/heating stage and micro-Raman spectroscopy with the following aims: (1) to characterize the range in fluid compositions and fluid densities, (2) to calculate minimum pressures of fluid entrapment from density data and temperature estimates for pegmatite crystallization based on pegmatite mineral assemblages, and (3) to assess possible relations between the compositions of the fluids, in particular their N contents, and potential sources of pegmatite parent melts. The pegmatite intruded into Al-rich metapelitic gneisses during the Permian tectonometamorphic event (∼290 Ma) and was overprinted at amphibolite-eclogite-facies P-T conditions during Eoalpine (∼80–90 Ma) metamorphism. It is characterized by a major phase assemblage quartz + muscovite + paragonite + albite with minor garnet + beryl and accessory columbite-group phases + cassiterite + ixiolite/wodginite + chrysoberyl + cordierite + staurolite + apatite + wyllieite-group phases + zircon. Two types of fluids are preserved in the phases investigated: (1) complex CO2±N2±CH4-H2O-NaCl±MgCl2±CaCl2 fluids with highly variable proportions of the constituent species trapped in all three host phases. The compositions of these fluids range from CO2-rich (∼72–92 mol.%) to N2-rich (∼25–66 mol.%) with additional minor (∼3–8 mol.%) CH4 contents; and (2) H2O-rich fluids with variable salinity (∼3–23 mass%) trapped in beryl and quartz. Trapping of CO2-N2-CH4 fluids in cassiterite along interfaces between the cassiterite host and columbite-group phase inclusions indicates that these fluids were present during joint cassiterite-columbite-group phase crystallization when the pegmatite solidified. In the absence of clear textural evidence for a successive trapping of the two types of fluids, a possible explanation for their simultaneous presence is fluid immiscibility. Isochores for fluid inclusions with the highest densities observed in cassiterite and beryl yield trapping pressures of ∼9–10 kbar for 650–700 °C. By comparison, temperatures estimated for pegmatite crystallization based on the assemblage beryl + chrysoberyl + gahnite and the stability of albite + muscovite + quartz lie in the range ∼650–700 °C. As a potential source of N for the N2-rich fluids, biotite and muscovite from the metapelites of the pegmatite host rocks were identified. Infrared analysis yields NH4 contents of 1430–1772 μg/g in biotite and of 297–489 μg/g in muscovite from two representative gneiss samples. This finding provides further evidence for an anatectic origin of most, if not all, Permian pegmatites found throughout the Austroalpine basement of the Eastern Alps.
Learning to suppress a location does not depend on knowing which location
Authors: Gao Ya , Theeuwes Jan
Published: February 2022

The present study investigated whether explicit knowledge and awareness regarding the regularities present in the display affects statistical learning (SL) in visual search. Participants performed the additional singleton paradigm in which a salient distractor was presented much more often in one location than in all other locations. Previous studies have shown that participants learn this regularity as the location that is most likely to contain a distractor becomes suppressed relative to all other locations. In the current study, after each trial, participants had to either indicate the location of the distractor or the location of the target. Those participants that reported the distractor location, were very much aware of the regularity present in the display. However, participants that reported the target location were basically unaware of the regularity regarding the distractor. The results showed no difference between these groups in the amount of suppression of the high-probability location. This indicates that regardless of whether participants had explicit knowledge or not, the suppression was basically the same. We conclude that explicit knowledge and awareness does not contribute to learning to suppress a location. This conclusion is consistent with the notion that statistical learning is automatic, operating without conscious effort or awareness.
Photothermal ablation of murine melanomas by Fe3O4 nanoparticle clusters
Authors: Wang Xue , Xuan Lili , Pan Ying
Published: February 2022

Melanoma is one of the deadliest forms of cancer, for which therapeutic regimens are usually limited by the development of resistance. Here, we fabricated Fe3O4 nanoparticle clusters (NPCs), which have drawn widespread attention, and investigated their role in the treatment of melanoma by photothermal therapy (PTT). Scanning electron microscopy imaging shows that our synthesized NPCs are spherical with an average diameter of 329.2 nm. They are highly absorptive at the near-infrared wavelength of 808 nm and efficient at locally converting light into heat. In vitro experiments using light-field microscopy and cell viability assay showed that Fe3O4 NPCs, in conjunction with near-infrared irradiation, effectively ablated A375 melanoma cells by inducing overt apoptosis. Consistently, in vivo studies using BALB/c mice found that intratumoral administration of Fe3O4 NPCs and concomitant in situ exposure to near-infrared light significantly inhibited the growth of implanted tumor xenografts. Finally, we revealed, by experimental approaches including semi-quantitative PCR, western blot and immunohistochemistry, the heat shock protein HSP70 to be upregulated in response to PTT, suggesting this chaperone protein could be a plausible underlying mechanism for the observed therapeutic outcome. Altogether, our results highlight the promise of Fe3O4 NPCs as a new PTT option to treat melanoma.

The genus Fusarium includes numerous important plant and human pathogens, as well as many industrially and commercially important species. During our investigation of fungal diversity in China, a total of 356 fusarioid isolates were obtained and identified from diverse diseased
and healthy plants, or different environmental habitats, i.e., air, carbonatite, compost, faeces, soil and water, representing hitherto one of the most intensive sampling and identification efforts of fusarioid taxa in China. Combining morphology, multi-locus phylogeny and ecological preference,
these isolates were identified as 72 species of Fusarium and allied genera, i.e., Bisifusarium (1), Fusarium (60), and Neocosmospora (11). A seven-locus dataset, comprising the 5.8S nuclear ribosomal RNA gene with the two flanking internal transcribed spacer (ITS) regions,
the intergenic spacer region of the rDNA (IGS), partial translation elongation factor 1-alpha (tef1 ), partial calmodulin (cam), partial RNA polymerase largest subunit (rpb1 ), partial RNA polymerase second largest subunit (rpb2 ) gene regions, and partial β-tubulin
(tub2 ), were sequenced and employed in phylogenetic analyses. A genus-level phylogenetic tree was constructed using combined tef1 , rpb1 , and rpb2 sequences, which confirmed the presence of four fusarioid genera among the isolates studied. Further phylogenetic
analyses of two allied genera (Bisifusarium and Neocosmospora ) and nine species complexes of Fusarium were separately conducted employing different multi-locus datasets, to determine relationships among closely related species. Twelve novel species were identified and
described in this paper. The F. babinda species complex is herein renamed as the F. falsibabinda species complex, including descriptions of new species. Sixteen species were reported as new records from China.

Addressing the leading risk factors for ill health
Authors: Everest Grace , Marshall Louise , Fraser Caroline , Briggs Adam
Published: February 2022

Smoking, poor diet, physical inactivity and harmful alcohol use are leading risk factors driving the UK’s high burden of preventable ill health and premature mortality. All are socioeconomically patterned and contribute significantly to widening health inequalities. This Health Foundation report summarises recent trends for each of these risk factors and looks at national-level policies for England, introduced or proposed by the UK government between 2016 and 2021. The report reviews the government’s approach and finds a heavy reliance on policies aimed at changing individual behaviour and an uneven approach across risk factors, with particularly weak action on alcohol. The report also identifies that decision making across departments has been disjointed, undermining health improvement targets.

Приводятся результаты литологических исследований и палеогеографических реконструкций позднепалеозойского этапа развития и особенностей формирования осадочных формаций южного борта Прикаспийского осадочного бассейна. Сложное геологическое строение региона обусловлено, главным образом, влиянием тектонических, вулканических и денудационных процессов на осадконакопление, которые происходили в зоне сочленения области кряжа Карпинского, Донбасско-Астраханской зоны, Северного Устюрта и Урала. Блоковая структура фундамента значительно влияло на продолжительность этапов седиментации и формирование как карбонатных платформ, так и зон с преимущественно терригенным накоплением осадков. Различные глубины залегания фундамента, определяют изменчивость литологического состава и мощностей отложений палеозоя. Проведена типизация разрезов карбонатных платформ в пределах бортовых зон Прикаспийской впадины, которая позволила выявить связь условий осадконакопления и блоковой структуры фундамента.

дительности алмазных буровых коронок при бурении твердых абразивных пород. Для достижения этой цели созданы многослойные коронки, в матрице которых размещены несколько алмазных импрегнированных слоев «гребешкового» профиля, представляющего круговые конусные выступы и впадины. Упомянутые импрегнированные слои по высоте чередуется с безалмазными слоями меньшей твердости и абразивности. Созданные на этом принципе казахстанские алмазные коронки под маркой КСБ прошли сравнительные испытания с коронками ведущих фирм США, Канады, Китая, России при бурении самых твердых абразивных пород. Установлено, что лучшей коронкой по критерию эффективности (отношение стоимости коронки к пробуренным ею метрам скважины) оказалась коронка КСБ. С целью дальнейшего совершенствования алмазных инструментов разработана и запатентована алмазная коронка, у которой разновысотные импрегнированные слои гребешкового профиля размещены на многозаходной винтовой поверхности. Ожидается, что такая коронка позволит при бурении использовать существующий эффект предварительного ослабления прочности породы, мощность которой в 5-10 раз превышает глубину внедрения алмазных зерен. С использованием современных методов дополнительной сортировки и классификации получена партия высокопрочных термостойких алмазных шлифпорошков с высокой их однородностью по прочности и линейным размерам. Исследовано влияние физико-механических характеристик: прочности, термостойкости, однородности по прочности шлифпорошков алмаза на износостойкость буровых коронок. Показано, что оснащение буровых коронок алмазами после их сортировки для повышения прочности, термостойкости и однородности по прочности и размерам зерен алмаза приводит к снижению интенсивности их изнашивания.

анспортировке нефти. Проведен анализ физико-химических характеристик нефти (в товарной форме) различных месторождений нефти и пластовой воды с данных месторождений. Показано наличие в нефти некоторых агрессивных компонентов, в то время как пластовая вода содержит большое количество хлорид-ионов, кислорода и имеет высокую минерализацию. Содержание воды в пробах нефти не превышало допустимых нормативных показателей. Проведены коррозионные испытания на модельных установках – лабораторной и укрупненной. Установлено что для исследованной нефти (в товарной форме) коррозионная активность практически отсутствует. При содержании воды в нефтесмеси, в предельно допустимых нормативных концентрациях - 0,5 и 1%, значения скорости коррозии металла увеличились до 0,044 г/м2 ч (или 0,049 мм/год) и 0,103 г/м2 ч (или 0,115 мм/год), соответственно. При этом поверхность металла покрыта практически однородным по структуре слоем коррозионных отложений по всей внутренней поверхности образцов. Сделан вывод о том, что даже предельное нормативно допустимое количество воды в нефти (0,5% и 1%, согласно СТ РК 1347-2005) может способствовать интенсификации процессов коррозии на внутренней поверхности нефтепровода в среднем в 2-16 раза, по сравнению с нефтью, содержащей следовые количества воды

Published: February 2022

In the aerospace field, titanium alloys are extensively used for the airframe and engine parts to improve aircraft fuel consumption. Drilling through these parts in a single-shot process to produce high quality holes is challenging. During drilling, high temperatures are generated owing to the friction between the cutting tool and workpiece, causing the process becomes inefficient in terms of tool life and surface quality. To reduce the temperature produced in the cutting zone, different types of cooling techniques during drilling have been used by researchers. In this study, the feasibility of quarry dust suspension as coolant in drilling of titanium alloy was performed. The effects of different concentrations of quarry dust on surface roughness, thrust force, and burr formation were evaluated, and their machining performances were compared with those obtained using aluminium oxide suspension. Before the experiments, both suspensions were prepared by dispersing quarry dust and aluminium oxide particles into deionised water at various concentrations ranging from 0 wt% to 0.10 wt%. Results indicated that by using 0.06 wt% of quarry dust suspension, thrust force and surface roughness showed an improvement by 8.31% and 18.29%, respectively, compared with those of aluminium oxide suspension at the same concentration. The burr height formed at the drilled holes using 0.06 wt% of quarry dust was also lower than that formed with aluminium oxide suspension at the same concentration.

Patients with diabetes mellitus experience delayed wound healing because of the uncontrolled glucose level leads to impaired cell proliferative function, poor circulation, decreased production and repair of new blood vessels. Polydeoxyribonucleotide (PDRN) is used in wound healing as a substance that stimulates tissue repair. A hydrogel is a reticular substance generally used as a dressing formulation to accelerate wound healing, and also used as a bio-applicable scaffold or vehicle. The aim of study is to investigate the effects of PDRN loaded in hydrogel on wound healing, in combination and separately, in an animal diabetic wound model.
Methods: We studied the effects of PDRN in diabetes-related healing defect using an incisional skin-wound model produced on the back of male diabetic rats. A total of 36 wounds, were classified into 3 groups: a control group, a hydrogel-only group, a PDRN loaded in hydrogel combined-treatment group. All rats were assessed for changes in wound size and photographed on scheduled dates. The skin specimen sample of diabetic rat wound model were observed on 3, 7, 14 and 21 days after skin injury to measure tissue remodeling through histological evaluation of fibroblasts proliferation, and collagen production, also the number of blood vessels was measured in all specimens.
Results: Differences in the decrease and change in wound size in the PDRN loaded in hydrogel group were more significant than those in the control and hydrogel single-treatment groups. Analysis of the fibroblasts proliferation, collagen production and number of blood vessels through histological examination showed a pattern of increase over time that occurred in PDRN loaded in hydrogel combined-treatment group.
Conclusion: This experiment demonstrated improved wound healing using a PDRN loaded in hydrogel combined treatment compared to either two groups, resulting in a decrease in diabetic wound size and a shortening of the healing period

Published: February 2022

BACKGROUND: Pneumopericardium (PPC) is one of the rarest pulmonary air leak syndromes, but the incidence is the highest in the neonatal period. Risk factors include premature infants with respiratory distress (RD) syndrome, receiving active resuscitation, meconium aspiration syndrome, and aggressive mechanical ventilation. Several cases have also been reported related to COVID-19.

CASE PRESENTATION: We report a case of a female newborn with a birth weight of 3300 grams a COVID-19 confirmed 35-year-old G3P2A0 mother. The baby was not crying at born and the amniotic fluid was stained green. The baby experienced RD and was intubated. A babygram was performed at the age of 5 h with the impression of a too deep endotracheal tube, neonatal pneumonia, and PPC. COVID-19 RT-PCR examination of the baby was positive. There were no signs of cardiac tamponade, so it was decided to take conservative and supportive management.

CONCLUSION: Resolution of PPC was found on repeated babygram 26 h later. The baby was then discharged after 19 days of treatment.
Online trade as a serious additional threat to the Critically Endangered silvery pigeon Columba argentina in Indonesia
Authors: Bruslund Simon , Leupen Boyd , Shepherd Chris R. , Nelson S. Sunny
Published: February 2022

The elusive and Critically Endangered silvery pigeon Columba argentina is only found on small offshore islands in western Indonesia and Malaysia. Historically, trade records have suggested that, in addition to habitat degradation and invasive predators, commercial exploitation could be a threat to the species. The current study confirms this to be the case, with a relatively high volume of silvery pigeons found offered for sale on social media platforms in Indonesia between October and December 2021. The trade numbers (at least 10 individuals) observed within this short period exceeded 20% of the global silvery pigeon population according to the latest Red List assessment, suggesting that actual population numbers may be larger than previously thought but also confirming that trade poses a considerable threat. Some of the recorded posts were in new areas within the species’ presumed range, further suggesting that the population may be slightly larger than hitherto assessed. The reported trade observations are reason for grave concern, particularly given the potential interest of international collectors which could further drive demand and increase prices. Due to the locations of the observed online trade we recommend timely field surveys to confirm the species’ presence and current status, particularly in the Riau-Lingga island group, as well as the development of a species conservation action plan to catalyse local and regional efforts to tackle the current illegal trade and work towards the regulation of international trade.
Revision of Neotropical Scythrididae moths and descriptions of 22 new species from Argentina, Chile, and Peru (Lepidoptera, Gelechioidea)
Authors: Nupponen Kari , Sihvonen Pasi
Published: February 2022

The taxonomy of South American Scythrididae (Lepidoptera: Gelechioidea) is revised, based on external morphology, genitalia, male abdominal segment VIII, and DNA barcodes using genetic distances, BINs, and a tentative molecular phylogeny. Data include both historical and fresh specimens from Argentina, Brazil, Colombia, Chile, Ecuador, Paraguay, and Peru. Thirty-four species are recognised as valid, and the fauna classified in three genera. Type specimens and morphology of all species are described and figured in detail. DNA barcode sequences of the COI gene were successful for 22 species, the average genetic divergence between species being 5.1%. A key to Neotropical Scythrididae species is provided, based on the male genitalia and abdominal segment VIII, which show most and easily accessible interspecific differences.

Our study revealed that the Scythridae fauna of South America is more or less completely unknown. As a result, 22 new species are described, increasing the number of South American Scythrididae species from 13 to 34. All new species are authored by Kari Nupponen (incertae sedis means the genus combination is uncertain and needs further research, country of the type locality is given in parentheses): Rhamphura subdimotasp. nov.

The following new combinations are proposed: Scythris depressa Meyrick, 1931 and Scythris dimota Meyrick, 1931 are transferred from Scythris Hübner, 1825 to Rhamphura Landry, 1991 comb. nov. Three species classified in Scythris earlier are now classified as Scythris (incertae sedis): Scythris dividua Meyrick, 1916, S. medullata Meyrick, 1916 and S. notorrhoa Meyrick, 1921. The taxon Syntetrernis neocompsa Meyrick, 1933, recently classified in Scythrididae: Scythris, is excluded from Scythrididae and it is now classified in Cosmopterigidae incertae sedis.
Redescription of the giant Southeast Asian millipede Spirobolus macrurus Pocock, 1893 and its assignment to the new genus Macrurobolus gen. nov. (Diplopoda, Spirobolida, Pachybolidae)
Authors: Pimvichai Piyatida , Enghoff Henrik , Backeljau Thierry
Published: February 2022

A new genus of the millipede family Pachybolidae from Southeast Asia is described: Macrurobolusgen. nov., with Spirobolus macrurus Pocock, 1893 as type species. This latter species is DNA barcoded (COI) and redescribed based on male morphological characters, which hitherto were unknown. The new genus differs from other pachybolid genera by having (1) the preanal ring process long and protruding beyond the anal valves and (2) the anterior gonopod telopodite distally abruptly narrowed, forming an extremely long, slender, elevated process curved caudad. Given that Macrurobolusgen. nov. is a monotypic genus, it is aphyletic and thus requires further taxonomic revision.
Le dévoilement performatif du « peuple » : une réflexion sur les bandes à pied et la politique de la rue en Haïti
Authors: Kivland Chelsey L. , Périvier Mathilde , Yepes Daniel , Kivland Chelsey L. , Motta Marco , Despland Basile
Published: February 2022

Cet article présente les bann a pye haïtiennes – les bandes à pied, les fanfares du carnaval – comme des plateformes stratégiques pour la critique politique de la gouvernance néolibérale. Au travers d’une ethnographie d’une bande à pied dans un quartier populaire de Port-au-Prince, je montre comment la bande se forme et se présente elle-même comme un porte-parole de son quartier défavorisé et de la population démunie qui y vit. Bien que la bande soit très critique de l’État, elle n’appelle pas à en finir avec celui-ci ; au contraire, elle exige une présence plus soutenue et engagée de sa part afin d’améliorer les conditions de vie des citadins pauvres. Les efforts continus de la bande pour reconstituer un État qui répond aux besoins de la population du quartier contredit les conceptualisations dominantes en sciences sociales qui postulent l’État comme une force répressive qui doit nécessairement être défiée, à laquelle on doit se dérober ou dont la structure doit être démantelée. Les chansons de ces bandes nous rappellent qu’en face d’un secteur public vicié, l’État resurgit comme le socle ambitieux d’une société juste et équitable.
Jwèt mò . L’engendrement du désordre en Haïti
Authors: Beckett Greg , Despland Basile , Motta Marco
Published: February 2022

Cet article est un chapitre traduit et extrait de There Is No More Haiti : Between Life and Death in Port-au-Prince. Greg Beckett y explore la manière dont la crise politique est ressentie et dont divers agents puissants « font le désordre ». Avec pour toile de fond la crise de 2004 qui a abouti à l’exil du président Jean-Bertrand Aristide et à l’arrivée d’une intervention militaire internationale, cet article montre comment les résidents urbains de Port-au-Prince ont utilisé le concept haïtien dezòd pour donner un sens à la crise politique, ressentie comme inéluctable et délibérément créée par des agents puissants cherchant à prendre le contrôle de l’État.
Éthiquette éclair, un éclat de lumière sur l’école haïtienne
Authors: Érard Yves
Published: February 2022

Le système scolaire haïtien souffre de deux injonctions paradoxales : a) l’école est gratuite est obligatoire, mais l’État haïtien n’a ni les moyens de garantir cette gratuité ni les moyens de faire respecter cette obligation ; b) l’enseignement doit se faire en français alors que le créole est majoritairement la langue du quotidien. Un gain en expression scolaire implique souvent une perte de confiance dans sa langue maternelle. Cet article veut donner une vue de cette double insécurité quand elle est vécue par celles et ceux qui y sont soumis (y compris l’auteur de ces lignes, qui est aussi soumis aux injonctions paradoxales qu’il décrit). C’est une invitation à rencontrer l’école en Haïti avec toutes celles et tous ceux qui la font tous les jours. La description des déterminismes sociaux et linguistiques se situe à la bonne hauteur de sa réalité ordinaire : sur le fil des jours.
Auto-affirmation et relations intergroupes : le rôle des différences interindividuelles et du contexte normatif
Authors: Badea Constantina
Published: February 2022

Dans cet article, nous examinons les facteurs qui peuvent influencer l’efficacité des interventions basées sur la théorie de l’auto-affirmation dans la réduction des attitudes intergroupes négatives à l’égard des minorités issues de l’immigration. On distingue l’affirmation du soi individuel, accomplie par la mobilisation des valeurs centrales pour l’individu, de l’affirmation du soi collectif, réalisée par le rappel des valeurs importantes pour le groupe d’appartenance. Nous présentons des études empiriques montrant que l’effet bénéfique de l’affirmation du soi individuel sur la réduction des préjugés à l’égard des immigrés est modéré par des différences individuelles telles que l’orientation politique des participants ou leur penchant pour l’individualisme versus collectivisme. En revanche, l’effet de l’affirmation du soi collectif sur la diminution des préjugés peut être entravé par le contexte normatif inégalitaire dans lequel l’intervention est implémentée. Des limites et de futures pistes de recherche sont discutées.
Nouveaux horizons sur la dissonance cognitive : développements récents, modèles intégratifs et pistes de recherche
Authors: Bran Alexandre , Vaidis David C.
Published: February 2022

Les modèles basés sur la consistance cognitive ont connu plusieurs développements récents qui replacent la théorie de la dissonance cognitive au cœur de nombreux débats. Si une partie des discussions revient sur les axiomes de la théorie de la dissonance cognitive, de nouveaux modèles suggèrent son intégration dans des ensembles plus larges. Afin de donner un regard complet sur ces nouvelles perspectives de recherche, nous développons quatre modèles particulièrement importants et issus de la dernière décennie : le Meaning Maintenance Model , le General Process Model of Threat and Defense , l’ Expectancy-Value Model et le modèle des conflits psycho-logiques. Ces nouveaux modèles mobilisent tous la théorie de la dissonance cognitive pour l’intégrer, la réinterpréter ou la compléter. Par conséquent, ces perspectives sont susceptibles d’orienter son développement futur. Dans une première partie, nous présentons ces modèles en nous centrant sur leurs apports et limites pour la dissonance. Dans la seconde partie, nous discutons des questions de recherches, antérieures ou issues de cette nouvelle vague, qui restent à examiner.
La keynote d’Apple au prisme des médias
Authors: Wiart Louis
Published: February 2022

L’efficacité et l’impact des keynotes dans la stratégie de communication d’Apple, où le lancement de nouveaux produits est mis en spectacle, découlent largement de l’écho médiatique considérable que cet évènement génère dans le monde. Une analyse lexicométrique à partir d’un corpus d’articles permet de caractériser cette présence d’Apple dans les médias et de faire ressortir les principales dimensions du discours de presse sur la keynote , où se jouent à la fois la mise en valeur des produits de la marque et celle de la stratégie du groupe.
De la republicitarisation . Contribution aux concepts pub *
Authors: Mouratidou Eleni
Published: February 2022

La recherche actuelle est une contribution aux concepts pub *. Elle observe les transformations des discours publicitaires à travers l’étude des stratégies et médiations d’acteurs principalement marchands. Elle pointe une double métamorphose, communicationnelle et identitaire, discutée à travers le concept de remédiation . Il s’agit de montrer que cette dernière est constitutive des concepts pub * et structure le mouvement qui les caractérise, appelé ici republicitarisation . La republicitarisation est analysée à la lumière de la relation qu’elle entretient avec les médias investis et avec la publicité-même, dans une optique réflexive.
Les trois états du « native advertising ». Usages sociaux et régimes de circulation d’une innovation terminologique
Authors: Bullich Vincent
Published: February 2022

Le «  native advertising  » s’est imposé comme incontournable dans le paysage médiatique en ligne. Polymorphe, il a investi de nombreuses entreprises de presse, de production de contenus ou d’agences-conseils. Cet article se propose de retracer l’histoire de cette « innovation », plus terminologique que technique, au prisme de la question de l’autonomie de fonctionnement des industries culturelles. Trois états de cette innovation ont ainsi été distingués en fonction des usages sociaux et des régimes de circulation du syntagme, afin de soutenir l’hypothèse d’une subordination progressive de ces industries aux exigences des marques-annonceurs.
Introduction. Le trouble développemental du langage : enjeux actuels
Authors: Maillart Christelle
Published: February 2022

Le trouble développemental du langage (TDL) est une pathologie neurodéveloppementale fréquente (environ 7 % des enfants d’âge préscolaire et scolaire) mais peu connue. Cet article distingue cinq enjeux actuels qui sont importants pour la compréhension et la prise en charge du TDL : 1) la prise en considération de la spécificité des langues et du multilinguisme, 2) l’importance de recourir à l’appellation commune « TDL » suivant les recommandations du consortium CATALISE, 3) l’évolution de la conception du TDL, 4) le TDL envisagé comme un trouble d’apprentissage du langage et 5) les conséquences sociales, émotionnelles et comportementales du TDL, y compris l’impact fonctionnel et la qualité de vie. Considérés ensemble, ces différents objectifs devraient permettre d’appréhender la complexité et l’impact des troubles du langage oral sur le développement.
L’hypothèse du déficit procédural : apport pour la compréhension du trouble développemental du langage, sa spécificité et ses comorbidités
Authors: Juvené Élodie , Thomas Nathalie , Aeby Alec , Urbain Charline
Published: February 2022

Un ensemble d’études menées au cours de ces 15 dernières années montrent des performances d’apprentissage procédural altérées dans le trouble développemental du langage (TDL). Bien que des résultats contradictoires soient parfois rapportés, l’hypothèse du déficit procédural dans le TDL est prometteuse car elle offre une meilleure compréhension des profils de comorbidités complexes fréquemment observés chez ces patients. Dans ce contexte, un certain nombre de données suggèrent qu’un dysfonctionnement des circuits cérébraux soutenant la mémoire procédurale puisse également expliquer une partie des difficultés observées dans des troubles fréquemment associés au TDL, tels que le trouble développemental de la coordination (TDC) ou le trouble spécifique des apprentissages (TSAp) avec déficit en lecture. Ici aussi, des résultats contradictoires appellent à poursuivre ces recherches. Enfin, plusieurs études suggèrent que les patients présentant un TDL ou un TSAp en lecture compensent une partie de leurs difficultés langagières ou procédurales au moyen de connaissances et stratégies cognitives dépendantes de la mémoire déclarative. Cette hypothèse pourrait non seulement améliorer la prise en charge de ces patients, mais également, ouvrir de nouvelles pistes d’interventions thérapeutiques à d’autres troubles neurodéveloppementaux.
Nonword repetition to identify DLD in older school-age children
Authors: Thordardottir Elin , Reid Heather
Published: February 2022

Objectifs. La haute valeur diagnostique des tests de répétitions de non-mots (RNM) pour identifier le trouble développemental du langage (TDL) a été largement démontrée pour les enfants monolingues et bilingues d’âge préscolaire et scolaire. Cette étude étend l’analyse de la RNM à des enfants plus âgés. Méthodologie. Un test existant de RNM en langue française dont l’efficacité diagnostique a été démontrée pour l’âge de 5 ans a été complété par des items comprenant 6 à 8 syllabes, et ressemblant ou non à des mots. Ce test a été administré à 64 participants incluant des enfants de CE2, de 6 e et des adultes ainsi qu’un groupe d’enfants bilingues et un groupe d’enfants présentant un TDL. Résultats. Les enfants TDL ont obtenu des scores globalement plus faibles quelle que soit la longueur des items, ont commis davantage d’erreurs et ont été moins aidés par le fait que le non-mot ressemble à un mot. Les enfants bilingues présentant un développement typique ont obtenu des scores similaires à leurs pairs monolingues. Un effet d’âge n’a été trouvé qu’entre les adultes et les deux groupes d’enfants. Conclusions. Les enfants plus âgés ont besoin de tâches de RNM plus complexes. L’efficacité diagnostique de la RNM chez les enfants plus âgés peut être améliorée en utilisant des composants du score et non le score global.

Les faiblesses de la flexicurité et la crise financière
Authors: Burroni Luigi , Keune Maarten
Published: February 2022

La “flexicurité” est devenue un concept influent dans le discours académique et politique, en particulier depuis que la Commission européenne l’a placé au cœur de la Stratégie Européenne pour l’Emploi. Toutefois, le concept souffre d’un certain nombre de lacunes graves ; dans cet article, nous discutons de ses caractéristiques problématiques et de la difficulté de faire des politiques basées sur ce concept en temps de crise économique.
