Cursos, percursos e transcursos da antropologia no Piauí
Authors: Gontijo Fabiano , Pessoa Maria Lídia
Published: February 2021

O artigo apresenta algumas reflexões sobre as particularidades da formação e do processo de consolidação do campo disciplinar da antropologia no estado brasileiro do Piauí. O que caracteriza e diferencia o perfil da formação da antropologia no Piauí em relação à antropologia nacional talvez seja a sua estreita associação com a história, com a literatura, com a psicanálise e com a arqueologia desde seus primórdios, mas também a feminilização da profissão e, enfim, o atendimento a demandas voltadas para o desenvolvimento sustentável.
A institucionalização da antropologia no Nordeste
Authors: De Carvalho Maria Rosário
Published: February 2021

O artigo, partindo do caráter memorialista e desdobrando as notas para a atividade “Conversa com o Autor”, durante a 43ª Reunião da ANPOCS, em 2019, e do esforço de produção do Memorial apresentado para o concurso de professor Titular, recupera o campo da antropologia praticada no Nordeste, com foco no contexto etnológico. A autora se apropria de forma reflexiva da sua formação, que tem seu ingresso na Faculdade de Filosofia e Ciências Humanas, da Universidade Federal da Bahia, no departamento de antropologia e etnologia, no final da década de 1970, tendo percorrido anteriormente a licenciatura e o bacharelado em Ciências Sociais, no início da mesma década, sob a orientação do professor Pedro Agostinho. Reflete-se aqui os desafios e as constrições resultantes do período de repressão política. Refletindo-se sobre o campo da etnologia indígena, na Bahia, recupera-se a importância do projeto de pesquisa sobre as Populações Indígenas da Bahia, em 1971, e que é renomeado, em 1980, como Programa de Pesquisa sobre os Povos Indígenas do Nordeste Brasileiro. A hipótese defendida é que, apesar de se creditar uma mudança substantiva na Antropologia a partir da implantação dos primeiros programas de pós-graduação, quando se recupera o contexto etnológico – e a trajetória da autora é utilizado como material comprovatório –, pode-se constatar que se fazia antropologia desde o início do século XX, com um caráter de pesquisa científica, mesmo com o autodidatismo. Apresenta-se também, como elementos agregadores da hipótese, o processo de institucionalização da antropologia na região Nordeste, no Ceará e Pernambuco.
A instituição do PET-Antropologia na UFCG e o fortalecimento da presença feminina na antropologia no Nordeste brasileiro
Authors: Lima Elizabeth Christina de Andrade , Caniello Márcio , Silva Vanderlan
Published: February 2021

O artigo apresenta a implantação do Programa de Educação Tutorial (PET) Antropologia na Universidade Federal da Paraíba, campus II, transformada em 2002 na Universidade Federal de Campina Grande. Analisa, ainda, os impactos do Programa nas trajetórias acadêmicas das estudantes bolsistas, com destaque para o empoderamento feminino no cotidiano do PET Antropologia e na Graduação em Ciências Sociais, desde sua implantação, no ano de 1988, até os dias atuais. Na primeira parte do artigo, discutimos o processo de implantação, as bases filosóficas e as metodologias de trabalho do Programa. Na sequência, são analisadas as transformações implantadas pelo Ministério da Educação, que mudaram não apenas o significado da sigla PET, até então Programa Especial de Treinamento, passando a ser designado Programa de Educação Tutorial, bem como as bases filosóficas originais do programa e suas metodologias de trabalho. O texto foi elaborado a partir de pesquisas documentais em arquivos da UFCG, do PET Antropologia e dos arquivos pessoais dos autores. Realizamos ainda dez entrevistas com mulheres que participaram do programa em vários momentos de sua história, de modo online, através do programa de troca de mensagens da rede social WhatsApp, cujas respostas foram disponibilizadas de forma escrita e oral. Nos resultados e conclusões, demonstramos que o PET Antropologia tem gerado impactos positivos na vida acadêmica e profissional dos alunos bolsistas e empoderado o gênero feminino, cujas consequências podem ser sentidas na antropologia do Nordeste e do Brasil, mediante a atuação de muitos profissionais cujas origens acadêmicas remontam ao PET Antropologia.
Análise do uso de insumos tecnológicos na agricultura nordestina
Authors: Pereira Caroline
Published: February 2021

A agricultura nordestina cresceu substancialmente nas últimas décadas em função do dinamismo dos polos produtivos de grãos e frutas que surgiram nos anos 1970. Estes polos, apesar de concentrados em determinadas áreas, vêm espraiando a produção para seu entorno. Com isso, o objetivo deste trabalho é analisar a evolução do uso do pacote tecnológico, como irrigação, tratores, agrotóxicos e fertilizantes na agricultura nordestina, bem como a orientação técnica recebida. A pergunta que motiva o artigo é se o uso de tecnologias apresentou maior massificação e homogeneidade ou se restringe aos polos produtivos tradicionais? A hipótese do trabalho é que o uso de tecnologias agrícolas segue restrito nos espaços convencionais voltados para a agricultura de exportação. Utilizou-se dados dos Censos Agropecuários 2006 e 2017 para o levantamento de dados produtivos e do uso de insumos agrícolas. Concluiu-se que de certo modo a concentração persiste nos espaços convencionais, com algum espraiamento para os novos polos frutícolas na Bahia, que vem demandando maior uso de adubação e irrigação.
Contornos sinuosos de justiça ecológica
Authors: Moruzzi Marques Paulo Eduardo , Blanc Julien
Published: February 2021

O artigo focaliza o crescimento do bairro Demétria, em Botucatu/SP, local de nascimento de uma importante iniciativa brasileira em favor da agricultura biodinâmica, braço da filosofia antroposófica. A análise se apoia na teoria das justificações, a partir da qual foi concebida a metodologia de pesquisa. Nesta ótica, a noção de justiça ecológica foi particularmente mobilizada. Com efeito, é possível considerar que as mudanças no bairro, com a instalação de muitos residentes e com grande conversão no uso do solo, enfraquecem a perspectiva de construção de um mundo justo e ecológico, com inspiração na antroposofia. Todavia, as forças de resistência local, diante de uma mutação desestruturante dos ideais fundadores do bairro, procuram inclusive difundir propostas assentadas em valores ecológicos para além das fronteiras do bairro, com êxito limitado.
Gênero e modernização da agricultura
Authors: Folster de Paula Fernanda
Published: February 2021

Este artigo analisa as transformações que ocorreram na agricultura e nas relações de gênero no oeste catarinense, nas décadas de 1970, 80, e 90, recortando as unidades de produção camponesas. Partindo do relato das mulheres camponesas, militantes do Movimento de Mulheres Camponesas (MMC), que viveram tais transformações, resgatadas por meio de onze entrevistas semi-estruturadas, a hipótese que guia este trabalho é a de que a emergência do trabalho integrado, uma das características da modernização da produção agrícola no oeste catarinense, transforma os modos de produzir do campesinato, mobilizando a diferença de gênero e acirrando desigualdades. Argumenta-se que o estabelecimento de contratos de integração entre as famílias camponesas e as agroindústrias e, posteriormente, o agronegócio, concorrem para naturalizar uma generificação do trabalho produtivo e reprodutivo. Os homens tornam-se os responsáveis e gestores da produção; e as mulheres são cada vez mais associadas ao trabalho de reprodução, de modo que o trabalho das mulheres no âmbito produtivo vai se tornando progressivamente invisibilizado. A partir deste caso, este artigo explora as consequências analíticas da relação entre modernização da agricultura, divisão sexual do trabalho e desigualdades de gênero.
Distributed UFIR Filtering with Applications to Environmental Monitoring
Authors: Vazquez-Olguin Miguel , Shmaliy Yuriy S. , Ibarra- Manzano Oscar , Marquez-Figueroa Sandra
Published: February 2021

Environmental monitoring requires an analysis of large and reliable amount of data collected through node stations distributed over a very wide area. Equipments used in such stations are often expensive that limits the amount of sensing stations to be deployed. The technology known as Wireless Sensor Networks (WNS) is a viable option to deliver low-cost sensor information. However, electromagnetic interference, damaged sensors, and the landscape itself often cause the network to suffer from faulty links as well as missing and corrupted data. Therefore robust estimators are required to mitigate such effects. In this sense, the unbiased finite impulse response (UFIR) filter is used as a robust estimator for applications over WSN, especially when the process statistics are unknown. In this paper, we investigate the robustness of the distributed UFIR (dUFIR) filter with optimal consensus on estimates against missing and incorrect data. The dUFIR algorithm is tested in two different scenarios of very unstable WSN using real data. It is shown that the dUFIR filter is more suitable for real life applications requiring the robustness against missing and corrupted measurements under the unknown noise statistics.
Is the Word "Consumer" Biasing Trademark Law?
Authors: Marlan Dustin
Published: February 2021

Our trademark law uses the term “consumer” constantly, reflexively, and unconsciously to label the subject of its purpose—the purchasing public. According to the U.S. Supreme Court, trademark law has “a specialized mission: to help consumers identify goods and services they wish to purchase, as well as those they want to avoid.” As one leading commentator puts it, “trademarks are a property of consumers’ minds,” and “the consumer, we are led to believe, is the measure of all things in trademark law.”

Much criticism has been rightly levied against trademark law’s treatment of the consumer as passive, ignorant, and gullible. For instance, consumers are seen as requiring protection from any and all marketplace confusion and have no standing to sue under the Lanham Act. However, that a contributing factor to such treatment could be the linguistic bias stemming from the law’s label of the buying public as mere consumers—rather than, for instance, “citizens,” “persons,” “individuals,” or “humans”—has not, until now, been directly addressed.

This Article urges those involved in trademark and advertising law—e.g., judges, lawyers, lawmakers, and scholars—to rethink our ubiquitous use of the derogatory consumer label. To this end, the Article first explores “consumer” as a dehumanizing, anti-ecological, and nonsensical metaphor for “one that utilizes economic goods.” It then examines social psychology experiments finding that use of “consumer” has potentially deleterious effects for society given the negative stereotypes that it engenders as a social categorization. The Article claims, by extension, that the implicit linguistic bias inherent in consumer rhetoric might contribute to trademark law defining the public in a manner that is patronizing, biased, insulting, and indulgent of likelihood-of- confusion claims. The Article suggests that we either work to phase out the “consumer” label and replace it with more appropriate terminology (e.g., “citizen”), or at least pause to acknowledge the word’s potentially biasing effects.
Análisis de y desde la mirada en "Largo noviembre de Madrid" y en otros cuentos de Juan Eduardo Zúñiga
Authors: Vega-Sampayo Elena , Dávila-Montes José
Published: February 2021

El presente artículo propone un análisis de los cuentos de Largo noviembre de Madrid, además de otros relatos de La trilogía de la guerra civil, de Juan Eduardo Zúñiga desde un planteamiento multidisciplinar basado en el concepto de la mirada. Partiendo de un macro teórico lacaniano, y con la evidencia de la construcción lectora que requiere el estilo elíptico y elusivo del autor, se ofrece un abordaje en clave escópica que incide en la diferencia entre “ver” y “mirar” como elementos que articulan las relaciones psicológicas entre personajes, y como técnica que redunda en la inmersión lectora. En los cuentos de Zúñiga, que exigen un lector cómplice, se suele ver sin mirar, y se puede mirar sin ver. Se analiza e interpreta la presencia y frecuencia de la unidad léxica “ojos” y en qué medida la visión condiciona los finales de los relatos e incide en su estructura. Por último, a partir del análisis de las páginas centrales del cuento “Ruinas, el trayecto: Guerda Taro” de Capital de la gloria, se postula la existencia de una poética a posteriori de La trilogía de la guerra civil como epítome de la ejecución técnica de la mirada en el relato de Zúñiga.

El caso en análisis, que plantea un conflicto entre un particular y su obra social por la cobertura de una prótesis importada, nos remite a cuestiones que, están íntimamente ligadas con el derecho a la salud, tanto de índole procesal como sustancial.

Ello así, analizaremos - en primer lugar - las nociones fundamentales sobre el derecho a la salud y particularmente su vinculación con los conflictos entre afiliados y obras sociales.

Por otra parte, ahondaremos en la acción de amparo como la vía idónea para encaminar los reclamos tendientes a obtener la tutela efectiva del derecho a la salud. Profundizaremos las exigencias para su admisibilidad y revisaremos si las limitaciones procesales propias de aquella acción son compatibles con el derecho de defensa de las obras sociales.

Nos abocaremos también al estudio del criterio de nuestro Supremo Tribunal con respecto de arbitrariedad de sentencias denegatorias de recursos.

Por último, analizaremos el voto en disidencia del Dr. Rosatti y las cuestiones procesales derivadas del mismo.

Derecho a la Salud intramuros
Authors: Copello Nadia Virginia
Published: February 2021

Un hombre, con un estado de salud delicado, se encontraba detenido en un establecimiento penitenciario. A partir de informes médicos advierten que su patología requiere de un tratamiento que no puede llevarse a cabo, en condiciones óptimas, dentro de la unidad carcelaria. Lo que motivó a la defensa técnica del detenido a solicitar un arresto domiciliario.

Este contexto, nos conduce al análisis de las personas privadas de libertad como sujetos de derechos, el derecho a una atención integral de salud, tanto como a las condiciones carcelarias dignas.

Asimismo, surgen dos cuestiones relevantes. Por un lado, el habeas corpus como el mecanismo mediante el cual se pretende subsanar cualquier situación que implique un agravamiento en las condiciones de detención. Por otro, la entrada en vigencia de normas del nuevo Código Procesal Penal Federal.

Por último, será necesario reflexionar sobre el contraste de las normas y la realidad carcelaria.

 

A man, in a delicate state of health, was detained in a prison facility. From medical reports, they warn that their pathology requires treatment that cannot be carried out, in optimal conditions, within the prison unit. This motivated the technical defense of the detainee to request a house arrest.

This context leads us to the analysis of people deprived of liberty as subjects of rights, the right to comprehensive health care, as well as dignified prison conditions.

Also, two relevant issues arise. On the one hand, habeas corpus as the mechanism by which it is intended to correct any situation that implies an aggravation of the conditions of detention. On the other, the entry into force of regulations of the new Federal Criminal Procedure Code.

Finally, it will be necessary to reflect on the contrast of the rules and the prison reality.

Break-in, vandalism, car burglary – some of the crimes often involving glass breaking, in which physical-chemical expert examinations can help a lot in identifying the offender and solving the crime. In Hungary, the beginning of forensic glass examination dates back to the 1960s. In the nearly six decades since then, the methods used in the investigations have evolved a lot and expanded significantly. In addition to the classical physical parameters on which the comparison was based in the early days, the assessment of determination of origin by the most modern instrumental methods has given better-founded results, and besides it has also been possible to build a database. The aim of our paper is to present, after a brief historical overview, the process of forensic glass examination in the Hungarian Institute for Forensic Sciences, its applied methods, as well as the statements that can be made on the basis of the obtained results. In addition, in the light of a case study, we also illustrate in detail the difficulties and limitations of forensic glass examination.

NASA’s Transiting Exoplanet Survey Satellite (TESS) mission is expected to discover hundreds of planets via single transits first identified in their light curves. Determining the orbital period of these single-transit candidates typically requires a significant amount of follow-up work to observe a second transit or measure a radial velocity (RV) orbit. In Yao et al., we developed simulations that demonstrated the ability to use archival photometric data in combination with TESS to “precover” the orbital period for these candidates with a precision of several minutes, assuming circular orbits. In this work, we incorporate updated models for TESS single transits, allowing for eccentric orbits, along with an updated methodology to improve the reliability of the results. Additionally, we explore how RV observations can be used to follow up single-transit events, using strategies distinct from those employed when the orbital period is known. We find that the use of an estimated period based on a circular orbit to schedule reconnaissance RV observations can efficiently distinguish eclipsing binaries from planets. For candidates that pass reconnaissance RV observations, we simulate RV monitoring campaigns that enable one to obtain an approximate orbital solution. We find that this method can regularly determine the orbital periods for planets more massive than 0.5 M
J with orbital periods as long as 100 days.
Medium-band Observation of the Neutrino Emitting Blazar, TXS 0506+056

TXS 0506+056 is a blazar that has been recently identified as the counterpart of the neutrino event IceCube-170922A. Understanding the blazar type of TXS 0506+056 is important to constrain the neutrino emission mechanism, but the blazar nature of TXS 0506+056 is still uncertain. As an attempt to understand the nature of TXS 0506+056, we report the medium-band observation results of TXS 0506+056, covering the wavelength range of 0.575–1.025 μm. The use of the medium-band filters allows us to examine if there were any significant changes in its spectral shapes over the course of one month and give a better constraint on the peak frequency of synchrotron radiation with quasi-simultaneous data sets. The peak frequency is found to be 1014.28 Hz, and our analysis shows that TXS 0506+056 is not an outlier from the blazar sequence. As a way to determine the blazar type, we also analyzed if TXS 0506+056 is bluer-when-brighter (BL Lac type and some flat spectrum radio quasars, FSRQs) or redder-when-brighter (found only in some FSRQs). Even though we detect no significant variability in the spectral shape larger than observational error during our medium-band observation period, the comparison with a data set taken in 2012 shows a possible redder-when-brighter behavior of FSRQs. Our results demonstrate that medium-band observations with small to moderate-sized telescopes can be an effective way to trace the spectral evolution of transients such as TXS 0506+056.
Intrusion of MeV–TeV Cosmic Rays into Molecular Clouds Studied by Ionization, the Neutral Iron Line, and Gamma Rays
Authors: Fujita Yutaka , Nobukawa Kumiko K. , Sano Hidetoshi
Published: February 2021

Low-energy (∼ MeV) cosmic rays (CRs) ionize molecular clouds and create the neutral iron line (Fe i Kα) at 6.4 keV. On the other hand, high-energy (≳GeV) CRs interact with the dense cloud gas and produce gamma rays. Based on a one-dimensional model, we study the spatial correlation among ionization rates of gas, 6.4 keV line fluxes, and gamma-ray emissions from a molecular cloud illuminated by CRs accelerated at an adjacent supernova remnant. We find that the spatial distributions of these three observables depend on how CRs intrude the cloud and on the internal structure of the cloud. If the intrusion is represented by slow diffusion, the 6.4 keV line should be detected around the cloud edge where ionization rates are high. On the other hand, if CRs freely stream in the cloud, the 6.4 keV line should be observed where gamma rays are emitted. In the former, the cooling time of the CRs responsible for the 6.4 keV line is shorter than their cloud crossing time, and it is opposite in the latter. Although we compare the results with observations, we cannot conclude whether the diffusion or the free-streaming is dominantly realized. Our predictions can be checked in more detail with future X-ray missions such as XRISM and Athena and by observations of ionization rates that cover wider fields.
On the Thermally Pulsing Asymptotic Giant Branch Contribution to the Light of Nearby Disk Galaxies
Authors: Martínez-García Eric E. , Bruzual Gustavo , González-Lópezlira Rosa A. , Rodríguez-Merino Lino H.
Published: February 2021

The study of the luminosity contribution from thermally pulsing asymptotic giant branch (TP-AGB) stars to the stellar populations of galaxies is crucial to determine their physical parameters (e.g., stellar mass and age). We use a sample of 84 nearby disk galaxies to explore diverse stellar population synthesis models with different luminosity contributions from TP-AGB stars. We fit the models to optical and near-infrared (NIR) photometry, on a pixel-by-pixel basis. The statistics of the fits show a preference for a low-luminosity contribution (i.e., high mass-to-light ratio in the NIR) from TP-AGB stars. Nevertheless, for 30%–40% of the pixels in our sample a high-luminosity contribution (hence low mass-to-light ratio in the NIR) from TP-AGB stars is favored. According to our findings, the mean TP-AGB star luminosity contribution in nearby disk galaxies may vary with Hubble type. This may be a consequence of the variation of the TP-AGB mass-loss rate with metallicity, if metal-poor stars begin losing mass earlier than metal-rich stars, because of a pre-dust wind that precedes the dust-driven wind.
M-subdwarf Research. II. Atmospheric Parameters and Kinematics

We applied the revised M subdwarf classification criteria discussed in Zhang et al. to Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR7 and combined the result with the M subdwarf sample from Savcheva et al. to construct a new M subdwarf sample for further study. The atmospheric parameters for each object were derived from fitting to the PHOENIX grid, and the sources with available astrometry and photometry from Gaia DR2 were combined for further analysis. The relationship between the gravity and metallicity was explored according to the locus both in the color–absolute magnitude diagram and the reduced proper motion diagram. Objects that have both the largest gravity and the lowest metallicity are located away from the main-sequence cloud and may be considered as the intrinsic M subdwarfs, which can be classified as luminosity class VI. Another group of objects whose spectra show typical M subdwarf characteristics have lower gravity and relatively moderate metal deficiency and occupy part of the ordinary M dwarf region in both diagrams. The Galactic U, V, W space velocity components and their dispersion show that the local Galactic halo population sampled in the solar neighborhood is represented by objects of high gravity and an inconspicuous bimodal metallicity distribution, with a fraction of prograde orbits. The other M subdwarfs seem to belong in part to the thick disk component, with a significant fraction of thin disk, moderately metal-poor objects intricately mixed with them. However, selection effects, especially the favored anticenter direction of investigation in the LAMOST subsample, as well as contamination by multiplicity and parameter coupling, could play important roles and need to be investigated further.
Growth and Morphology of Water-, Methanol-, and Ethanol-ice Dust Grains Formed in an Astrophysically Relevant Plasma Experiment
Authors: Chai Kil-Byoung
Published: February 2021

Ice dust grains composed of water, methanol, and ethanol are successfully produced in a laboratory plasma experiment operating at astrophysically relevant temperatures. Both methanol- and ethanol-ice grains grow in an elongated and branched way similar to water-ice grains formed in a plasma. The experiment reveals that methanol- and ethanol-ice grains grow faster, larger, and more branched (spikier) than water-ice grains. The observed growth features seem to be related to the fact that more source molecules and monomer grains can exist in the system at the same temperature. The observed morphology is in agreement with the characteristics of the diffusion-limited aggregation. We also find that larger and more branched ice grains form when the ambient gas pressure is low or the mass of the ambient gas is light, indicating that the aggregation of small grains is enhanced under these conditions.

We detect Lyα emission in the dark core of the DLA trough at a 3.3σ confidence level, with Lyα luminosity of L

The associated galaxy is at very small impact parameter of ≲12 kpc from the background quasar, which is in line with the observed anticorrelation between column density and impact parameter in spectroscopic searches tracing the large-scale environments of DLA host galaxies.

Submillimeter spectral line and continuum emission from the protoplanetary disks and envelopes of protostars is a powerful probe of their structure, chemistry, and dynamics. Here we present a benchmark study of our modeling code, RadChemT, that for the first time uses a chemical model to reproduce ALMA C18O (2–1), and CARMA 12CO (1–0) and N2H+ (1–0) observations of L1527; this allows us to distinguish the disk, the infalling envelope, and outflow of this Class 0/I protostar. RadChemT combines dynamics, radiative transfer, gas chemistry, and gas–grain reactions to generate models that can be directly compared with observations for individual protostars. Rather than individually fit abundances to a large number of free parameters, we aim to best match the spectral line maps by (i) adopting a physical model based on density structure and luminosity derived primarily from previous work that fit spectral energy distribution and 2D imaging data, updating it to include a narrow jet detected in CARMA and ALMA data near (≤75 au) the protostar, and then (ii) computing the resulting astrochemical abundances for 292 chemical species. Our model reproduces the C18O and N2H+ line strengths within a factor of 3.0; this is encouraging considering the pronounced abundance variation (factor >103) between the outflow shell and CO snowline region near the midplane. Further, our modeling confirms suggestions regarding the anticorrelation between N2H+ and the CO snowline between 400 au and 2000 au from the central star. Our modeling tools represent a new and powerful capability with which to exploit the richness of spectral line imaging provided by modern submillimeter interferometers.

Using the near-IR spectroscopy of the MOSFIRE Deep Evolution Field survey, we investigate the role of the local environment in the gas-phase metallicity of galaxies. The local environment measurements are derived from accurate and uniformly calculated photometric redshifts with well-calibrated probability distributions. Based on rest-frame optical emission lines, [N ii]λ6584 and Hα, we measure gas-phase oxygen abundances of 167 galaxies at 1.37 ≤ z ≤ 1.7 and 303 galaxies at 2.09 ≤ z ≤ 2.61, located in diverse environments. We find that at z ∼ 1.5, the average metallicity of galaxies in overdensities with M

⊙ is higher relative to their field counterparts by 0.094 ± 0.051, 0.068 ± 0.028, and 0.052 ± 0.043 dex, respectively. However, this metallicity enhancement does not exist at higher redshift, z ∼ 2.3, where, compared to the field galaxies, we find 0.056 ± 0.043, 0.056 ± 0.028, and 0.096 ± 0.034 dex lower metallicity for galaxies in overdense environments with M

Our results support the hypothesis that, at the early stages of cluster formation, owing to efficient gas cooling, galaxies residing in overdensities host a higher fraction of pristine gas with prominent primordial gas accretion, which lowers their gas-phase metallicity compared to their coeval field galaxies. However, as the universe evolves to lower redshifts (z ≲ 2), the shock-heated gas in overdensities cannot cool down efficiently, and galaxies become metal-rich rapidly due to the suppression of pristine gas inflow and re-accretion of metal-enriched outflows in overdensities.
WIYN Open Cluster Study. LXXXIV. The Effect of Chromospheric Activity on Oxygen Abundances from the 7774 Å Triplet in Pleiades Dwarfs

Published: February 2021

We present a spectroscopic analysis of 7774 Å O i triplet abundances, 8498–8662 Å Ca ii triplet chromospheric activity, and rotation in the Pleiades open cluster, with the objective of thoroughly examining the O triplet overabundance trends observed in cool open cluster dwarfs, and to thereby make clear the cause of that trend. High-dispersion, contemporaneous spectra of the O i triplet, Ca ii triplet, and Hα spectral regions in 41 Pleiades dwarfs were acquired using Hydra on the WIYN 3.5 m telescope. Our Ca ii emission equivalent-width data exhibit a strong positive correlation with decreasing T
eff, with the rapidly rotating stars enhanced by up to 50% above the slowly rotating stars. Our triplet [O/H] values exhibit a statistically significant positive correlation with total Ca ii triplet emission, and similarly, significant correlations have been found by every study to date that used contemporaneous O triplet abundance and chromospheric activity data, which is strong evidence that chromospheric activity is the cause of the observed overabundance trends. Based on the slowly rotating, low Ca ii emission stars in the near-solar range 5450 K < T
eff < 6100 K, we find a cluster mean [O/H] = + 0.143 ± 0.061, consistent with the substantial super-solar [O/H] values exhibited by most young ( < 1 Gyr) open clusters. We also find a cluster mean [Fe/H] = + 0.029 ± 0.034, in excellent agreement with previous studies.

Solar wind stream interaction regions (SIRs) are often characterized by energetic ion enhancements. The mechanisms accelerating these particles, as well as the locations where the acceleration occurs, remain debated. Here, we report the findings of a simulation of a SIR event observed by Parker Solar Probe at ∼0.56 au and the Solar Terrestrial Relations Observatory-Ahead at ∼0.95 au in 2019 September when both spacecraft were approximately radially aligned with the Sun. The simulation reproduces the solar wind configuration and the energetic particle enhancements observed by both spacecraft. Our results show that the energetic particles are produced at the compression waves associated with the SIR and that the suprathermal tail of the solar wind is a good candidate to provide the seed population for particle acceleration. The simulation confirms that the acceleration process does not require shock waves and can already commence within Earth’s orbit, with an energy dependence on the precise location where particles are accelerated. The three-dimensional configuration of the solar wind streams strongly modulates the energetic particle distributions, illustrating the necessity of advanced models to understand these particle events.

Published: February 2021

Cet article interroge, en lien avec la théorie du contrat psychologique, la signification de la mobilité interne pour les cadres. À partir de trois études de cas, la recherche met en avant le rôle clé de la mobilité interne dans les contrats psychologiques. L’un des cas étudiés met à jour une nouvelle forme de contrat psychologique : commutabilité contre fluidité. Cette commutabilité constitue une nouvelle « méta-compétence », nécessaire au développement des carrières dans l’entreprise agile.
Heureux qui comme Ulysse… Amarrage des ancres de carrière et de l’employabilité dans la carrière protéenne

À l’instar de Protée, divinité marine poly morphe qui conserve son identité à travers ses changements de formes, de nos jours les carrières prennent plusieurs apparences. Ainsi pouvons-nous avancer que l’ individu navigue d’une entreprise à une autre (carrière sans frontière), qu’il est capitaine à bord (carrière protéenne) et qu’ il doit garder le cap (carrière intelligente). Dans le cadre de cette recherche nous étudions, plus particulièrement, les liens existants entre les ancres de carrière et l’employabilité dans le cadre d’une carrière protéenne. Dit autrement, nous cherchons à savoir dans quelle mesure les ancres de carrière influencent-elles l’employabilité dans le cadre d’une carrière protéenne. Pour répondre à cette problématique une méthodologie quantitative a été mobilisée : 313 questionnaires ont été administrés auprès de collaborateurs d’entreprises de plus de 1 000 salariés, situées en France. Ainsi, cette recherche met en exergue 3 points fondamentaux : (1) la relation positive significative entre ancres de carrière et employabilité ; (2) en fonction des dimensions de l’employabilité les individus peuvent avoir plusieurs ancres de carrière ; (3) dans le cadre de la mobilité interne les individus ont une seule ancre qui influe sur l’intégralité de l’employabilité (ancre compétence technique/fonctionnelle). Par conséquent, le fait d’être reconnus experts, dans leurs domaines de compétences, augmente de facto l’employabilité perçue des individus avec l’ancre compétence technique/fonctionnelle.
Asymptomatic versus symptomatic patients: [18F]FDG-PET/CT patterns and evolutionary track of COVID-19 associated vasculitis
Authors: Sollini Martina , Gelardi Fabrizia , Chiti Arturo
Published: February 2021

Several patients experience unexplained persistent symptoms after recovering from severe acute respiratory syndrome-related coronavirus disease 2 (SARS-CoV-2) [the so-called long coronavirus disease (COVID)], with a negative impact on their quality of life. We report the evolutionary track of fluorine-18-fluorodeoxyglucose positron emission tomography-computed tomography ([18F]FDG-PET/CT) in two patients incidentally diagnosed with SARS-CoV-2 infection. In both cases, baseline PET/CT showed bilateral pneumonia associated with [18F]FDG vascular uptake. Vascular uptake was more evident in the baseline scan of the asymptomatic patient. Vice versa, it was more marked in the follow-up examinations of the patient who developed long COVID. These findings suggested that vascular inflammation and its duration are responsible for the clinical course of the disease and the development of long COVID.
