A INFLUÊNCIA DE LUDWIG FEUERBACH NA FILOSOFIA DE ENRIQUE DUSSEL
Authors: Lima João Paulo Araújo Pimentel
Published: April 2020

Na construção de um pensar autêntico latino-americano, o filósofo argentino Enrique Dussel, precursor da Filosofia da Libertação, irá trabalhar com a estratégia de que não é necessário negar a tradição filosófica anterior a ele para a construção de algo novo, pelo contrário, a proposta do autor é de um diálogo profundo com a história da filosofia, visto que a necessidade do novo pensar não surge apenas da pulsão criativa de se produzir originalidade, mas do alarmante fato de que toda a filosofia ocidental não incluiu no seu horizonte a alteridade última. Partindo da sua condição, do ser encoberto pela razão ocidental, Dussel elabora um pensamento ético que encontra em Feuerbach uma de suas maiores referências. O objetivo deste trabalho, então, é apresentar como Dussel se apropria das teorias do filósofo alemão na construção do seu próprio pensar. Abordaremos, principalmente, a obra Método para uma filosofia da libertação, na qual é descrita a apreciação de Dussel sobre o resgate feito por Feuerbach de, pelo menos, três questões fundamentais: a sensibilidade, que sempre fora colocada em suspeita pela tradição; o reconhecimento do outro, que emerge como alternativa à filosofia da subjetividade; e sua crítica a Hegel, que resplandece como crítica a qualquer pensar totalizante, ontológico. Finalmente, veremos como Dussel reconhece Feuerbach no grupo dos críticos de Hegel. Esse grupo, para ele, constitui a única filosofia válida para a realidade latinoamericana, da qual ele é um continuador, pois esses filósofos formam a pré-história da Filosofia da Libertação.
O INSIGHT PRÁTICO NO JUSNATURALISMO DE JOHN FINNIS: UMA TESE SOBRE A AQUISIÇÃO DOS FUNDAMENTOS DA MORAL
Authors: Miranda John Florindo de
Published: April 2020

Este trabalho apresenta a tese epistemológica de John Mitchell Finnis sobre a apreensão dos primeiros princípios da moral. Com base em uma interpretação específica de Aristóteles e Tomás de Aquino, Finnis sustenta que esses princípios são apreendidos pela razão através de atos de insight práticos sobre dados da sensibilidade e da razão teórica. A partir desses atos de insight práticos, a inteligência humana apreende uma série de primeiros princípios práticos que, de acordo com Finnis, são mais bem compreendidos através da concepção de lei natural de Tomás de Aquino. O presente texto se propõe a situar esse argumento dentro da teoria jusnaturalista de John Finnis e explanar os elementos que ele abarca, fornecendo uma visão jusnaturalista sobre como as faculdades humanas trabalham em conjunto com a experiência para a apreensão dos fundamentos da moral.
O SUJEITO, A VERDADE E A CRÍTICA AO PENSAMENTO MODERNO
Authors: Lima Márcio José Silva
Published: April 2020

O presente trabalho visa discutir a constituição do eu-sujeito fundado na Modernidade a partir do pensamento cartesiano, bem como a sua crítica e suas implicações no conceito de verdade. Para tanto, como elemento instigante na reflexão sobre o tema, apresentaremos a análise de Heidegger acerca da sentença de Protágoras em que profere o homem como medida de todas as coisas. Abordaremos também a crítica nietzschiana ao eu-sujeito fundamentada por ele nas obras A Genealogia da Moral, Além do Bem e do Mal e nos aforismos publicados na obra A Vontade de Poder. Em seguida teceremos considerações acerca do conceito de verdade que na Modernidade tornou-se sinônimo de comprovação científica.
O CARRAPATO DO LABORATÓRIO DE ROSTOCK: UM PARADIGMA DO SIMPLESMENTE VIVENTE
Authors: Manzi Ronaldo
Published: April 2020

Esse artigo busca colocar à tona um problema biopolítico fundamental para Agamben: a animalização do homem. De certo modo, essa animalização é decorrente da impossibilidade de delimitarmos com certeza o que é da esfera do humano e o que é da esfera do animal. O exemplo do carrapato do laboratório de Rostock é privilegiado nesse sentido: ele “embaralha” a distinção entre o que é próprio ao homem e ao animal, tal como propunha Heidegger. A proposta é mostrar que essa indistinção é inquietante tal como escreveu Freud em 1919 e, talvez, própria à história ocidental.
ARTE NA FILOSOFIA DE SARTRE: TENSÃO ENTRE IMAGINAÇÃO E ENGAJAMENTO
Authors: Souza Thana Mara de
Published: April 2020

O artigo pretende mostrar como Sartre pensa a obra de arte, obra concreta do imaginário e ao mesmo tempo engajamento, a partir principalmente dos livros O imaginário e Que é a literatura?, sem que isso constitua uma contradição. Trata-se de compreender que o imaginário nega o real mantendo-o como pano de fundo, de forma que, longe de ser alienação ou abstração, volta-se sempre a este para desvelá-lo, fazendo com que aqueles que criam a arte (tanto artista quanto público) compartilhem e se reconheçam no exercício conjunto de liberdade – o que torna a arte, como obra do imaginário, engajada.

JÜRGEN HABERMAS E JOHN RAWLS: UM DEBATE SOBRE O LIBERALISMO POLÍTICO
Authors: Orben Douglas João
Published: April 2020

Este artigo pretende apresentar os principais elementos envolvidos no debate ocorrido entre Jürgen Habermas e John Rawls, promovido pelo The Journal of Philosophy (v. 92, n. 3, março de 1995). O texto analisa, inicialmente, as três principais críticas habermasianas ao liberalismo político, as quais se dirigem, sobretudo, às seguintes problemáticas: a artificialidade da posição original, as limitações do consenso sobreposto e a primazia dos direitos liberais sobre o princípio democrático de participação. Na segunda parte do texto, procura-se responder tais críticas, principalmente a partir das considerações apresentadas por Rawls em seu artigo intitulado Political Liberalism: Reply to Habermas. Ainda, o presente artigo também pretende delimitar as diferenças e ressaltar os pontos de proximidade entre os dois autores.
POR UM ETHOS COSMOPOLITA SEM O RECURSO A UMA RELIGIÃO OU ESTADO GLOBAL: A RELEVÂNCIA DE KANT COMO FILÓSOFO POLÍTICO PARA O CONTEXTO WESTFALIANO
Authors: Santini Guilherme José
Published: April 2020

A pergunta pela possibilidade de uma justificação da experiência histórica segundo princípios exigidos pelo bom exercício da razão prática - já suposto que a História Universal deva ter um sentido ou propósito racional -, ela não aparece à toa no horizonte kantiano. Entender seu porquê requer o resgate do contexto político da era moderna. O primeiro objetivo deste artigo é esboçar os desafios políticos referentes a esse contexto e expor em seguida como a solução oferecida por Kant - a Sociedade das Nações e o direito cosmopolita - vai ao encontro da expectativa de pensar um sentido comunitário para um mundo fragmentado em Estadosnação sem ter de recorrer a uma autoridade global, fosse ela política ou religiosa. Apoiar-nosemos em dois textos escritos da Filosofia Política de Kant: Ideia de uma História Universal de um Ponto de Vista Cosmopolita, de 1784, e À Paz Perpétua, de 1795.

The Relation between Media Consumption and Misinformation
at the Outset of the SARS-CoV-2 Pandemic in the US
Authors: Hall Jamieson Kathleen , Albarracín Dolores
Published: April 2020

A US national probability-based survey during the early days of the SARS-CoV-2 spread in the US showed that, above and beyond respondents’ political party, mainstream broadcast media use (e.g., NBC News) correlated with accurate information about the disease's lethality, and mainstream print media use (e.g., the New York Times) correlated with accurate beliefs about protection from infection. In addition, conservative media use (e.g., Fox News) correlated with conspiracy theories including believing that some in the CDC were exaggerating the seriousness of the virus to undermine the presidency of Donald Trump. Five recommendations are made to improve public understanding of SARS-CoV-2.
Das verletzliche Subjekt als Anker politischer Korrektheit. Eine Problematisierung (sozial)pädagogischer Programme am Beispiel von Diversitätssensibilität und Kinderschutz in der bundesdeutschen Jugendhilfe
Authors: Frühauf Marie , Kessl Fabian
Published: April 2020

Zusammenfassung: Political correctness (politische Korrektheit) meint eine Sensibilisierung für andere als die üblichen Wissensquellen. Vorherrschende Ausblendungen und Ausschließungen sollen dadurch wahrnehmbar gemacht werden. Im vorliegenden Beitrag werden
jüngste Dynamisierungstendenzen politischer Korrektheit in den sozialpädagogischen Feldern in den Fokus gerückt. Am Beispiel der Diskussionen um eine Diversitätssensibilität sozialpädagogischer Fachkräfte und die Etablierung von Kinderschutz als verallgemeinerter
Gewaltprävention lässt sich die Figur des verletzlichen Selbst als zentrale Begründungsfigur für Positionen politischer Korrektheit beleuchten. Kinder und Jugendliche werden dabei zu einer Gruppe vulnerabler Akteur*innen und Erwachsene als deren potenziell gefährliches
Gegenüber konstruiert. Das erschwert allerdings die (sozial-)pädagogische Arbeit, denn die damit verbundenen pädagogischen Programme einer standardisierten Gefahrenabwehr und einer permanenten Selbstkorrektur werden mit einer grundlegenden Moralisierung verbunden, die die (selbst-)kritische
und problematisierende Reflexion erschwert, während Gefahrenabwehr und Selbstkorrektur die konstitutiv risikohafte Dimension des pädagogischen Tuns zu verdrängen suchen.
,,Man kann sich nur als das wehren, als was man angegriffen ist.“ Zur Debatte um Identitätspolitik und politische Korrektheit
Authors: Singer Mona
Published: April 2020

Zusammenfassung: Identitätspolitik ist in der politischen Diskussion zu einem Schlagwort geworden und wird neuerdings als Vorwurf gegen die Linke erhoben, partikularistische Politik zu betreiben und dabei Political Correctness als Strategie hoch zu halten. In meinem
Beitrag stelle ich die theoretischen Voraussetzungen und politischen Implikationen im Gebrauch des Begriffs Identitätspolitik heraus und argumentiere für einen fundamentalen Unterschied zwischen einer rechten Politik des Natürlichen und solcherart Identifizierens von Gruppen
einerseits und einer Politik des Widerstands gegen das so Identifiziert-Werden andererseits. Davon ausgehend wende ich mich gegen einen Begriff von ,,linker Identitätspolitik“. Politische Korrektheit verstehe ich als gesellschaftliche Notwendigkeit und als demokratisches Schutzschild
gegen das Sprechen der Rechten. Ich argumentiere damit gegen die Vorstellung einer politisch unschuldigen Sprache und stelle den Zusammenhang von Klassifikationen, Repräsentation und Machtverhältnissen heraus.

Empty nominalization over antonymous juxtaposition/coordination and the emergence of a new syntactic construction
Authors: Ogawa Yoshiki , Niikuni Keiyu , Wada Yuichi
Published: April 2020

In Japanese, direct combination of verbs or adjectives by coordination (with to 'and') or juxtaposition (with its empty counterpart) can form a NP, if the conjuncts are antonymous to each other; the coordinator to 'and' can combine only NPs elsewhere. We claim that this is because there is a phonetically empty nominalizer that can nominalize each conjunct, and that the new nominal construction has been gradually developing in the history of Japanese. An acceptability-rating experiment targeting 400 participants shows that the younger speakers were likely to judge this construction more acceptable than the older ones, that this tendency is slightly weaker in the Nominative condition than in the Genitive condition, and that the coordination condition was significantly worse than the juxtaposition condition.

Tripartite Motif-Containing 46 Promotes Viability and Inhibits Apoptosis of Osteosarcoma Cells by Activating NF-B Signaling Through Ubiquitination of PPAR
Authors: Jiang Wenwei , Cai Xinyu , Xu Tianyang , Liu Kaiyuan , Yang Dong , Fan Lin , Li Guodong , Yu Xiao
Published: April 2020

Osteosarcoma (OS), the most common bone cancer, causes high morbidity in children and young adults. TRIM46 is a member of the family of tripartite motif (TRIM)-containing proteins that serve as important regulators of tumorigenesis. Here we investigate the possible role of TRIM46 in
OS and the underlying molecular mechanism. We report an increase in the expression of TRIM46 in OS and its association with tumor size, Ennekings stage, and patient prognosis. TRIM46 knockdown inhibits OS cell viability and cell cycle progression and induces apoptosis, while TRIM46 overexpression
exerts inverse effects, which are inhibited by peroxisome proliferator-activated receptor alpha (PPAR) overexpression and the nuclear factor kappa B (NF-B) inhibitor, pyrrolidine dithiocarbamate (PDTC). Furthermore, TRIM46 negatively regulates PPAR expression via ubiquitination-mediated protein
degradation and modification. PPAR overexpression also inactivates NF-B signaling and NF-B promoter activity in OS cells overexpressing TRIM46. Moreover, TRIM46 knockdown inhibits tumor growth and induces apoptosis of OS cells in vivo. TRIM46 acts as an oncogene in OS by interacting with and
ubiquitinating PPAR, resulting in the activation of NF-B signaling pathway. Thus, TRIM46 may be a potential biomarker of carcinogenesis.

Authors: Konopleva Ekaterina S. , Bolotov Ivan N. , Spitsyn Vitaly M. , Kondakov Alexander V. , Gofarov Mikhail Yu. , Vikhrev Ilya V.
Published: April 2020

Here, we describe Contradens novoselovi sp. nov. (Bivalvia: Unionidae), a new freshwater mussel species from the Mekong Basin in Laos. Phylogenetic and morphological analyses reveal that the new taxon is closely related to Contradens comptus (Deshayes & Jullien, 1874) but can be distinguished from it by a smaller size, sub-ovate shell shape, tiny wrinkles near umbo, stronger pseudocardinal and lateral teeth, and fixed nucleotide substitutions. Contradens novoselovi sp. nov. is known only from the type locality in northwestern Laos and may represent a rare endemic species with restricted range.
Interannual Variability of Water Exchange Anomalies Between the Northern, Middle and Southern Caspian Based on Satellite Altimetry Data
Authors: Lebedev Sergey A. , Kostianoy Andrey G.
Published: April 2020

The paper presents the results of estimation of interannual and seasonal variability of water exchange between the Northern, Middle and Southern Caspian Sea based on the TOPEX/Poseidon and Jason–1/2/3 satellite altimetry data. The boundaries between the Caspian Sea sub-basins were taken along the 133 and 209 tracks of the satellites. Temporal variability of surface geostrophic velocities directed perpendicular to the tracks showed that positive values correspond to the southeast direction of the currents, negative values correspond to the northwest direction. It is clearly seen that the main water exchange associated with the Volga River runoff is concentrated along the western coast of the Caspian Sea. In this area, anomalies of geostrophic velocities exceed 20 cm/s. Total water exchange anomalies through the 133 and 209 tracks show seasonal variability with an amplitude up to ±18x105 m3/s for track 133 (a line between the Northern and Middle Caspian) and ±11x105 m3/s for track 209 (a line between the Middle and Southern Caspian). The maximum values of water exchange anomalies were observed in 1993, 1994 and 2012 through 133 track (±16-18x105 m3/s) and in 1993, 1996 and 1997 (±11x105 m3/s) through 209 track.

Çince’de Dört İmden Oluşmuş Deyimlerin İncelenmesi – (Kadın-Kız 女) İmi Üzerine
Authors: AZERTÜRK Semine İmge
Published: April 2020

Çincede günlük yaşamda önemli yer tutan deyimler, Çin toplumunun tarihini, kültürünü, dünya görüşünü ve yaşam biçimini zengin bir biçimde aktaran kaynaklardır. Çincede deyim, uzun kullanım sürecinden geçmiş, anlam ve içerik bakımından zengin, yazı ve edebi dilin özelliklerini taşıyan sabit sözcük grubudur. Deyimlerin büyük bir kısmı dört imin bir araya gelmesiyle oluşmuştur. Bu çalışma dört imden oluşmuş (kadın-kız 女) imi içeren, 127 deyim üzerinden yürütülmüştür. Çincede (kadın-kız 女) imi önemli ve sık kullanılan bir im olmakla birlikte aynı zamanda bir anahtar imdir. Kadın imi erkek iminden çok önce ortaya çıkmış, tek bir imden meydana gelmiş temel kök bir imdir. (Kadın-kız 女) imi, Çince deyimlerde sıklıkla karşımıza çıkmaktadır. (Kadın-kız 女) imi içeren deyimlerden, kadınlarla ilgili birçok tarihi, kültürel bilgiyi, Çin toplumundaki kadın algısını ve kadına yönelik cinsiyetçi yaklaşımı gözlemleyebilmekteyiz.

Çince dilbilgisinde sözcük sıralaması çok önemlidir. Çince’nin anlam değişikliği çoğunlukla sözcük sırası ile sağlanır. Bu çalışma, dört imden oluşmuş Çince deyimlerde (kadın-kız 女) imi içeren deyimler bağlamında, cinsiyet faktörünün Çince sözcük sıralamasına olan etkilerini incelemeyi amaçlamıştır.

İlk önce (kadın-kız 女) iminin oluşumuna değinilmiş, deyimler konularına göre sınıflandırılmış, daha sonra deyimler üç farklı açıdan nicel olarak incelenmiş, en son cinsiyet faktörünün sözcük sıralamasına olan etkisi, toplumsal yapı, düşünce yapısı ve cinsiyet ayrımcılığı başlıkları altında ele alınmıştır.

(Kadın-kız 女) imi içeren deyimlerin analizi sonucunda, cinsiyet kavramının Çince sözcük sırasını etkilediği, yani kadın iminin erkek imi ve erkeği ifade eden imlerle birlikte kullanıldığı deyimler içinde, sadece beş deyim dışındaki diğer bütün deyimlerde, (erkek 男) iminin ön sırada (kadın 女) iminin arka sırada yer aldığı, erkeği güçlü kadını zayıf ve erkeği öven kadını küçük gören cinsiyetçi yaklaşımların olduğu gözlemlenmiştir.
A Relationship between Stellar Age and Spot Coverage
Authors: Morris Brett M.
Published: April 2020

We investigate starspot distributions consistent with space-based photometry of F, G, and K stars in six stellar associations ranging in age from 10 Myr to 4 Gyr. We show that a simple light-curve statistic called the “smoothed amplitude” is proportional to stellar age as t
−1/2, following a Skumanich-like spin-down relation. We marginalize over the unknown stellar inclinations by forward modeling the ensemble of light curves for direct comparison with the Kepler, K2, and TESS photometry. We sample the posterior distributions for spot coverage with approximate Bayesian computation. We find typical spot coverages in the range 1%–10%, which decrease with increasing stellar age. The spot coverage is proportional to t

n
where n = −0.37 ± 0.16, also statistically consistent with a Skumanich-like t
−1/2 decay of starspot coverage with age. We apply two techniques to estimate the spot coverage of young exoplanet-hosting stars likely to be targeted for transmission spectroscopy with the James Webb Space Telescope, and estimate the bias in exoplanet radius measurements due to varying starspot coverage.
Probing the Innermost Regions of AGN Jets and Their Magnetic Fields with RadioAstron. III. Blazar S5 0716+71 at Microarcsecond Resolution

Published: April 2020

We present RadioAstron Space VLBI imaging observations of the BL Lac object S5 0716+71 made on 2015 January 3–4 at a frequency of 22 GHz (wavelength λ = 1.3 cm). The observations were made in the framework of the AGN Polarization Key Science Program. The source was detected on projected space–ground baselines up to 70,833 km (5.6 Earth diameters) for both parallel-hand and cross-hand interferometric visibilities. We have used these detections to obtain a full-polarimetric image of the blazar at an unprecedented angular resolution of 24 μas, the highest for this source to date. This enabled us to estimate the size of the radio core to be <12 × 5 μas and to reveal a complex structure and a significant curvature of the blazar jet in the inner 100 μas, which is an indication that the jet viewing angle lies inside the opening angle of the jet conical outflow. Fairly highly (15%) linearly polarized emission is detected in a jet region 19 μas in size, located 58 μas downstream from the core. The highest brightness temperature in the source frame is estimated to be >2.2 × 1013 K for the blazar core. This implies that the inverse-Compton limit must be violated in the rest frame of the source, even for the largest Doppler factor δ ∼ 25 reported for 0716+714.
Silicate Grain Growth due to Ion Trapping in Oxygen-rich Supernova Remnants like Cassiopeia A
Authors: Kirchschlager Florian , Barlow M. J. , Schmidt Franziska D.
Published: April 2020

Core-collapse supernovae can condense large masses of dust post-explosion. However, sputtering and grain–grain collisions during the subsequent passage of the dust through the reverse shock can potentially destroy a significant fraction of the newly formed dust before it can reach the interstellar medium. Here we show that in oxygen-rich supernova remnants like Cassiopeia A, the penetration and trapping within silicate grains of the same impinging ions of oxygen, silicon, and magnesium that are responsible for grain surface sputtering can significantly reduce the net loss of grain material. We model conditions representative of dusty clumps (density contrast of χ = 100) passing through the reverse shock in the oxygen-rich Cassiopeia A remnant and find that, compared to cases where the effect is neglected as well as facilitating the formation of grains larger than those that had originally condensed, ion trapping increases the surviving masses of silicate dust by factors of up to two to four, depending on initial grain radii. For higher density contrasts (χ ≳ 180), we find that the effect of gas accretion on the surface of dust grains surpasses ion trapping, and the survival rate increases to ∼55% of the initial dust mass for χ = 256.
Proton Perpendicular Heating in Turbulence Simulations: Determination of the Velocity Diffusion Coefficient
Authors: Vasquez Bernard J. , Isenberg Philip A. , Markovskii Sergei A.
Published: April 2020

Numerical methods are presented that can determine the perpendicular velocity space diffusion coefficient from kinetic simulation results. The methods are applied to hybrid simulation results using particle protons and a massless, quasi-neutralizing electron fluid for a case of quasi-perpendicular turbulence. During the quasi-steady phase of the turbulence, the evolution of the grid-averaged, gyrotropic, and peculiar velocity distribution of protons with velocity components perpendicular to the background magnetic field is found to be adequately described by diffusion. The estimated diffusion coefficient varies with perpendicular proton speed. A relative maximum occurs at a speed of zero. About the thermal speed, the coefficient decreases with increasing speed consistent with a power law with index −3. A relative minimum occurs at larger speeds, and the diffusion coefficient rises among the fastest protons contained in the simulation. The functional form of the diffusion coefficient appears to be the result of two sources. At speeds less than the relative minimum, the diffusion is dominated by turbulence generated fluctuations, while at greater speeds the diffusion arises from the large-scale fluctuations that initiated the turbulent energy cascade. Results are compared with theoretical predictions for the diffusion coefficient and with results presented from a previous simulation. Implications for generating suprathermal protons from quasi-perpendicular turbulence are also discussed.
Impact of the Collision Model on the Multi-messenger Emission from Gamma-Ray Burst Internal Shocks
Authors: Rudolph Annika , Heinze Jonas , Fedynitch Anatoli , Winter Walter
Published: April 2020

We discuss the production of multiple astrophysical messengers (neutrinos, cosmic rays, gamma-rays) in the Gamma-Ray Burst (GRB) internal shock scenario, focusing on the impact of the collision dynamics between two shells on the fireball evolution. In addition to the inelastic case, in which plasma shells merge when they collide, we study the Ultra Efficient Shock scenario, in which a fraction of the internal energy is re-converted into kinetic energy and, consequently, the two shells survive and remain in the system. We find that in all cases, a quasi-diffuse neutrino flux from GRBs at the level of 10−11–

(per flavor) is expected for protons and a baryonic loading of 10, which is potentially within the reach of IceCube-Gen2. The highest impact of the collision model for multi-messenger production is observed for the Ultra Efficient Shock scenario, that promises high conversion efficiencies from kinetic to radiated energy. However, the assumption that the plasma shells separate after a collision and survive as separate shells within the fireball is found to be justified too rarely in a multicollision model that uses hydrodynamical simulations with the PLUTO code for individual shell collisions.
Angular Momenta, Magnetization, and Accretion of Protostellar Cores
Authors: Kuznetsova Aleksandra , Hartmann Lee , Heitsch Fabian
Published: April 2020

Building on our previous hydrodynamic study of the angular momenta of cloud cores formed during gravitational collapse of star-forming molecular gas in Kuznetsova et al., we now examine core properties assuming ideal magnetohydrodynamics (MHD). Using the same sink-patch implementation for the Athena MHD code, we characterize the statistical properties of cores, including the mass accretion rates, specific angular momenta, and alignments between the magnetic field and the spin axis of the core on the 0.1 pc scale. Our simulations, which reproduce the observed relation between magnetic field strength and gas density, show that magnetic fields can help collimate low-density flows and help seed the locations of filamentary structures. Consistent with our previous purely hydrodynamic simulations, stars (sinks) form within the heterogeneous environments of filaments, such that accretion onto cores is highly episodic leading to short-term variability but no long-term monotonic growth of the specific angular momenta. With statistical characterization of protostellar cores properties and behaviors, we aim to provide a starting point for building more realistic and self-consistent disk formation models, helping to address whether magnetic fields can prevent the development of (large) circumstellar disks in the ideal MHD limit.

The characterization of the Intracluster Medium (ICM) properties of high-redshift galaxy clusters is fundamental to our understanding of large-scale structure formation processes. We present the results of a multiwavelength analysis of the very massive cluster MOO J1142+1527 at a redshift z = 1.2 discovered as part of the Massive and Distant Clusters of WISE Survey. This analysis is based on high angular resolution Chandra X-ray and NIKA2 Sunyaev–Zel’dovich (SZ) data. The cluster thermodynamic radial profiles have been obtained with unprecedented precision at this redshift and up to 0.7R
500, thanks to the combination of high-resolution X-ray and SZ data. The comparison between the galaxy distribution mapped in infrared by Spitzer and the morphological properties of the ICM derived from the combined analysis of the Chandra and NIKA2 data leads us to the conclusion that the cluster is an ongoing merger. We have estimated a systematic uncertainty on the cluster total mass that characterizes both the impact of the observed deviations from spherical symmetry and of the core dynamics on the mass profile. We further combine the X-ray and SZ data at the pixel level to obtain maps of the temperature and entropy distributions. We find a relatively low-entropy core at the position of the X-ray peak and high-temperature regions located on its south and west sides. This work demonstrates that the addition of spatially resolved SZ observations to low signal-to-noise X-ray data brings a high information gain on the characterization of the evolution of ICM thermodynamic properties at z > 1.

We study the solar eruptive event on 2017 September 10 that produced long-lasting >100 MeV γ-ray emission and a ground level enhancement (GLE72). The origin of the high-energy ions producing late-phase gamma-ray emission (LPGRE) is still an open question, but a possible explanation is proton acceleration at coronal shocks produced by coronal mass ejections. We examine a common shock acceleration origin for both the LPGRE and GLE72. The γ-ray emission observed by the Fermi-Large Area Telescope exhibits a weak impulsive phase, consistent with that observed in hard X-and γ-ray line flare emissions, and what appear to be two distinct stages of LPGRE. From a detailed modeling of the shock wave, we derive the 3D distribution and temporal evolution of the shock parameters, and we examine the shock wave magnetic connection with the visible solar disk. The evolution of shock parameters on field lines returning to the visible disk mirrors the two stages of LPGRE. We find good agreement between the time history of >100 MeV γ-rays and one produced by a basic shock acceleration model. The time history of shock parameters magnetically mapped to Earth agrees with the rates observed by the Fort Smith neutron monitor during the first hour of GLE72 if we include a 30% contribution of flare-accelerated protons during the first 10 minutes, having a release time following the time history of nuclear γ-rays. Our analysis provides compelling evidence for a common shock origin for protons producing the LPGRE and most of the particles observed in GLE72.
After 157 years, a second specimen and species of the phylogenetically enigmatic and previously monobasic genus Nototylus Gemminger & Harold, 1868 (Coleoptera, Carabidae, Nototylini)
Authors: Erwin Terry L. , Kavanaugh David H. , Maddison David R.
Published: April 2020

The enigmatic beetle tribe Nototylini (Carabidae) is revised and a key to species is provided. Two species from South America are included in the genus. One species,Nototylus fryi(Schaum), is reviewed and a second,Nototylus balliErwin & Kavanaugh,sp. nov., is described as new. Each species is known from a single specimen, neither of which is in good condition. The possible function of what appears to be a unique antennal grooming structure on the front femur is discussed.
Study on the Pauropoda (Myriapoda) from Tibet, China – Part II: New species and new record of the genus Samarangopus
Authors: Bu Yun
Published: April 2020

The pauropod family Eurypauropodidae Ryder, 1879 is recorded from Tibet, China for the first time. In this study, a new species Samarangopus zhongisp. nov. is described and illustrated from Motuo County, southeastern Tibet of China. It is distinguished from other species in this genus by having one pair of spiniform appendages on the sternum of the last trunk segment, 28–34 marginal protuberances on tergite I, the distal quarter of bothriotricha T3 golf-club-shaped, and the leaf-shaped seta st on tergum of pygidium. In addition, Samarangopus canalis Scheller, 2009 is newly recorded from China.
Cicatrices, scarifications et travail de frontière
Authors: de Luca Manuella
Published: April 2020

Les scarifications réalisent une incision qui provoque un écoulement sanguin et laisse une cicatrice plus ou moins visible et indélébile, qui fait l’objet d’un investissement particulier entre honte, vécu esthétique et puissance intense. Nous montrerons comment les cicatrices sont investies dans ce que nous nommons enjeux et travail de frontière, qui peut être trophique et soutenir un processus de transformation chez les adolescentes par le biais notamment dans la cicatrice, ou être délétère dans une répétition stérile de l’acte scarificatoire.

Le numérique, interférence avec le processus adolescent
Authors: Vlachopoulou Xanthie , Bittolo Christophe , Vicente Cindy , Robert Philippe
Published: April 2020

À l’heure du numérique et de la prolifération des écrans, l’adolescent va pouvoir mettre en scène ses désirs, défenses, conflits... L’utilisation des mondes virtuels, supports propices aux projections déterminés par la rencontre entre sa propre virtualité et celle de ces mondes pixellisés, va accompagner le processus adolescent. L’usage des mondes virtuels met le processus d’adolescence en pause, mais cela peut aller jusqu’à une répétition morbide désobjectalisante empêchant le devenir adulte.
L’agir violent numérique : aux frontières du réel
Authors: Colin Marie , Beuvelet Kathleen , Vavassori David , Harrati Sonia
Published: April 2020

L’adolescent d’aujourd’hui est pris dans ce que l’on nomme une hypermodernité. Avec l’avènement des technologies, de nouvelles modalités d’agir sont apparues telles que la violence numérique. À partir d’un cas clinique, les auteurs se proposent d’interroger l’agir violent numérique selon le référentiel psychanalytique. Plus précisément, ils discutent comment la défaillance familiale vient se déplacer sur une nouvelle scène, celle du numérique, pour tenter de restaurer les limites adolescentes.
Quel paradigme pour la psychose à l’adolescence ?
Authors: Sleiman Haidar Haya
Published: April 2020

L’article présente une construction théorique pour penser les manifestations d’allure psychotique à l’adolescence. Entre l’archaïque et l’actuel, le paradigme de la psychose pubertaire s’affranchit de la référence hâtive à la vulnérabilité schizophrénique pour redonner une valeur processuelle à la notion de potentialité. La psychose pubertaire dévoile un caractère éminemment frontalier et sa symptomatologie traduit des modalités de traitement qui s’étendent sur le spectre d’un travail du négatif nécessaire mais incertain.
Le rôle de la répétition dans la construction des frontières psychiques
Authors: Quagelli Luca
Published: April 2020

L’auteur s’appuie sur le matériel clinique issu de la psychothérapie d’un adolescent psychotique pour interroger les phénomènes de répétition à l’identique, leur signification et leur possibilité de transformation. Ces manifestations seraient liées à des échecs de la rencontre entre le sujet et son environnement premier, au moment où les frontières psychiques entre le dedans et le dehors, entre soi et l’autre, n’ont pas encore pu s’organiser.
L’adolescent et sa famille aux prises avec la paradoxalité
Authors: Philonenko Aymeric
Published: April 2020

La lecture métapsychologique du phénomène de double bind et de la paradoxalité psychique autorise la compréhension de leur importance dans la (dé)structuration psychique du sujet, ainsi que l’élaboration des manifestations transférentielles et contre-transférentielles que ceux-ci impliquent, dont la reconnaissance est un enjeu thérapeutique majeur. Enfin, le concept de paradoxe permet a fortiori de remettre au travail et « en jeu » les questions des limites et des frontières à l’adolescence.
La phobie scolaire aux confins de la psychose
Authors: Boë Emmanuelle
Published: April 2020

Avec la puberté, le vécu temporel se conflictualise et sort de la linéarité infantile. Ce processus se voit entravé par la survenue d’une phobie scolaire à l’adolescence, sans signe annonciateur antérieur. La pulsionalité y semble aussi gelée que le temps figé. S’y retrouve une quête d’immuabilité propre aux syndromes autistiques. Ici l’effet d’après-coup au lieu d’ouvrir à la temporalité réveille une faille des origines.

Les adolescents rencontrés dans notre unité de double prise en charge somato-psychiatrique dans un service de médecine de l’adolescent sont hospitalisés, car leur maladie et leurs traitements les empêchent de suivre une scolarité classique. À travers l’histoire de Medhi et sa participation au groupe « Corporescence », nous verrons comment en retraversant des jeux de l’enfance, il devient possible de se repositionner comme acteurs face à une maladie qui les a dans l’enfance parfois désubjectivés.

Péril psychosomatique lors de l’accès à la maternité et fonction contenante d’un réseau. À propos d’un cas
Authors: Pascoa Julie , Belot Rose-Angélique , Schneider Marie , Baseggio Anne , Nezelof Sylvie , Mellier Denis
Published: April 2020

Lorsque la propre fonction contenante du sujet est fragilisée et défaillante lors du devenir mère et qu’elle ne peut être compensée par l’environnement immédiat (conjoint, groupe familial proche, amis), une décompensation somatique peut survenir. Il s’agit alors de situations à haut risque où l’ensemble du réseau de soin, services hospitaliers et autres structures soignantes, est mis à contribution pour contenir la mère au plan somatique et psychique. Les équipes, les professionnels, deviennent les réceptacles des aspects non élaborés de la parturiente. Ils risquent alors de vivre à leur tour, de manière très intense et dans des positions bien différentes, ces éléments non contenus. Ce type d’accompagnement pour être opérant nécessite un profond travail de coopération au sein d’un réseau interdisciplinaire que nous pourrons décrire grâce à une situation emblématique.
L’accompagnement psychologique d’enfants victimes de sévices au Cambodge : la culture comme levier d’élaboration de l’expérience traumatique
Authors: Landbeck Alicia , Laurent Alexandra , Derivois Daniel
Published: April 2020

Les terrains humanitaires confrontent le psychologue aux enjeux culturels et linguistiques dans les interventions. Dans ces contextes, l’expression du traumatisme opère sur un fond culturel susceptible d’orienter la construction du dispositif pour un meilleur accompagnement. Au sein d’une ONG Khmère, nous avons mis en place un dispositif d’accompagnement basé sur différentes médiations. Dans ce cadre, nous avons rencontré 8 enfants présentant des symptômes marqués par la répétition, l’expression d’angoisse massive, souvent accompagnés par des représentations culturelles issues de l’animisme. Cet article a pour objectif de présenter la situation de Bonat, témoin de violences conjugales et confronté au décès de sa mère et de Kéa, victime d’inceste. Ce dispositif thérapeutique permet de comprendre comment le psychologue peut se saisir des dimensions culturelles amenées par l’enfant au sein du jeu et ainsi favoriser l’émergence de liens associatifs et intersubjectifs permettant à l’enfant de s’étayer sur des représentations qui ne lui auraient pas été disponibles.
Plato’s Phaedrus in Middle-Platonism: Some interpretations
Authors: Moreschini Claudio
Published: April 2020

Discuter de leurs propres doctrines selon une méthode “scolaire”, qui consiste à retrouver les doctrines de Platon afin de construire par ce moyen leur propre pensée, est une caractéristique commune aux médio-platoniciens. Un tel procédé est donc conditionné par l’exégèse de Platon ; d’ailleurs, l’exégèse elle-même devient un objet de discussion durant le moyen-platonisme, où surgit le problème très controversé de la meilleure interprétation de Platon. Une enquête sur la présence du Phèdre – qui était l’un des dialogues les plus lus de Platon – chez ces philosophes doit prendre en compte diverses méthodes d’interprétation mise en place, notamment l’interprétation grammaticale, l’interprétation physique et l’interprétation épistémologique, que cet article s’efforce de mettre en lumière.
Le véhicule autonome : se désengager et se réengager dans la conduite
Authors: Haué Jean-Baptiste , Bellu Sophie Le , Barbier Cécile
Published: April 2020

Avec l’arrivée du véhicule autonome, le conducteur sera amené à reprendre régulièrement la conduite d’un véhicule en déplacement et inséré dans un trafic. Ceci impliquera pour ce conducteur non seulement de reprendre le pilotage, mais aussi de se reconstruire une conscience de la situation adéquate (Situation Awareness - SA) pour évoluer en sécurité en étant capable d’anticiper les changements de trafic.Lors d’une étude portant sur les temps de reprise en main, menée auprès de quinze utilisateurs, deux participants ont été confrontés à leurs traces d’activité lors d’épisodes de reprise en main de la conduite juste après avoir été fortement engagés dans une tâche de vie à bord. L’utilisation de la notion d’engagement développée dans le cadre du programme de recherche cours d’Action montre comment le réengagement dans la conduite se construit dynamiquement. Ces deux cas d’étude approfondie suggèrent qu’avec la pression temporelle, un conducteur novice risque d’être orienté en premier vers ce que l’environnement lui offre de plus immédiat, à savoir le pilotage du véhicule. La construction d’une conscience de la situation (SA) n’intervient que dans un second temps. Ce moment de reprise en main et le changement radical d’orientation de l’activité qu’il implique offrent un terrain privilégié pour observer cet aspect dynamique de l’engagement. L’articulation des notions issues de la cognition située dresse un panorama des dynamiques de réengagement du couplage dans la conduite. Une typologie des processus de réengagement en est issue pour offrir des recommandations pour la conception.
Quelles conceptions de la coopération humains‑robots collaboratifs ?
Authors: Barcellini Flore
Published: April 2020

Cet article relate une expérience de participation de chercheures en ergonomie à un projet de recherche de développement d’un démonstrateur de robotique collaborative. Cette contribution empirique est mise en perspective avec des éléments théoriques portant sur les modèles de la coopération dans un système travailleur-robot et la conduite de projet de conception en ergonomie de l’activité. Sur cette base, nous discutons : (1) du modèle de la coopération effectivement réifiée dans le démonstrateur, qui en l’état des développements technologiques incorpore plus un modèle de coordination et non de coopération, en ce sens qu’il ne permet pas de gérer de manière dynamique l’interdépendance entre les tâches du travailleur et du robot ; (2) des apports et limites de la double conduite de projet mise en place (au sein du consortium de recherche et d’une usine). Nous soulignons que la présence de chercheures en ergonomie de l’activité au sein du projet de recherche s’est révélée être une condition nécessaire à la conception d’une technologie potentiellement « préservante » pour la santé et la performance, mais elle n’a en aucun cas été suffisante, car elle n’a pas permis de construite le futur usage socio-organisationnel de la technologie. Ceci appelle des perspectives de recherche permettant de poursuivre ces travaux en s’intéressant de plus près aux processus décisionnels relatifs aux transitions vers une « Industrie du futur » et à leurs accompagnements, dans des perspectives politiques et historico-culturel.
