Abstract
We present a detailed analysis of the Magellanic Bridge Cepheid sample constructed using the Optical Gravitational Lensing Experiment Collection of Variable Stars. Our updated Bridge sample contains 10 classical and 13 anomalous Cepheids. We calculate their individual distances using optical period–Wesenheit relations and construct three-dimensional maps. Classical Cepheid (CC) on-sky locations match very well neutral hydrogen and young stars distributions; thus, they add to the overall young Bridge population. In three dimensions, 8 out of 10 CCs form a bridge-like connection between the Magellanic Clouds. The other two are located slightly farther away and may constitute the Counter Bridge. We estimate ages of our Cepheids to be less than 300 Myr for from 5 up to 8 out of 10, depending on whether the rotation is included. This is in agreement with a scenario where these stars were formed in situ after the last encounter of the Magellanic Clouds. Cepheids’ proper motions reveal that they are moving away from both Large and Small Magellanic Clouds. Anomalous Cepheids are more spread than CCs in both two and three dimensions, even though they form a rather smooth connection between the Magellanic Clouds. However, this connection does not seem to be bridge-like, as there are many outliers around both Magellanic Clouds.

Abstract
We use the extended and updated Optical Gravitational Lensing Experiment (OGLE) Collection of Variable Stars to thoroughly analyze the distribution of RR Lyrae stars in the Magellanic Bridge. We use photometric metallicities to derive the absolute Wesenheit magnitude and individual distance of each RR Lyrae star. We confirm results from our earlier study showing that RR Lyrae stars are present in between the Magellanic Clouds, though their three-dimensional distribution more resembles two extended overlapping structures than a strict bridge-like connection. The contours do connect in the southern parts of the Bridge, albeit on a level too low to state that an evident connection exists. To test the sample numerically, we use multi-Gaussian fitting and conclude that there is no additional population or overdensity located in the Bridge. We also try to reproduce results on the putative RR Lyrae Magellanic Bridge stream by selecting RR Lyrae candidates from Gaia Data Release 1. We show that we are not able to obtain the evident connection of the Clouds without many spurious sources in the sample, as the cuts are not able to remove artifacts without eliminating the evident connection at the same time. Moreover, for the first time, we present the Gaia Data Release 2 RR Lyrae stars in the Magellanic Bridge area and show that their distribution matches our results.
Plasma-beta Modulated Characteristics of Magnetohydrodynamic Waves around the Heliospheric Current Sheet
Authors: Li Hui , Li Nianwang , Wang Chi , Yao Shuo 
Published: January 2020

Abstract
The magnetohydrodynamics (MHD) wave modes in the heliospheric current sheet (HCS) and the associated heliospheric plasma sheet (HPS) have not been comprehensively investigated in the literature. Based on a frequency-related identification approach, the properties of MHD waves are investigated during 154 HCS crossings observed by the Wind spacecraft from 1995 to 2013. Statistically, the incidence of MHD waves around HCS/HPS is found to be modulated by the plasma β within the HPS: (1) β > 5, both Alfvén and slow waves obviously decay within the HPS, with the occurrence rate (OR) decreasing from 60% and 20% in the upstream/downstream to 41% and 14% in the HPS vicinity, respectively; (2) 1 < β ≤ 5, the OR of Alfvén waves (AWs) remains nearly stable. However, more slow waves are generated after the HCS crossing, with OR increasing from 13% in the upstream/downstream to 22%; (3) β ≤ 1, the OR of Alfvén and slow waves remains at ∼58% and 20% during the entire crossing, in spite of some irregular fluctuations. The results for the HCS without a clear HPS are similar to the situations of a low β HPS. The parametric decay instability of AWs is proposed as being responsible for the more slow waves generated in the moderate β HPS, and some indirect observational clues are also given.
Analyse sémantique des formes ‹se-verbe› avec un argument oblique en français
Authors: Janic Katarzyna 
Published: January 2020

Dans la tradition scolaire du français, le classement des différentes formes ‹ se -verbe› est centré sur quatre prototypes : réfléchi, réciproque, passif et lexicalisé (Creissels 2006). Dans cette étude, nous examinons le cas peu documenté de l’antipassif. L’intérêt particulier se porte sur les formes de l’antipassif accompagnées d’un argument oblique. L’analyse proposée cherche à explorer ce phénomène, en le distinguant d’autres ‹ se -verbes› qui sont comparables dans une analyse de surface, mais qui relèvent en réalité de l’emploi réfléchi ou de l’emploi lexicalisé. À cette fin, nous approfondissons l’étude de l’aspect sémantique des formes ‹ se -verbe› à argument oblique.
Cultures juvéniles, lecture et lecteurs
Authors: Aquatias Sylvain 
Published: January 2020

Au contraire d’autres domaines culturels, la lecture reste un aspect des cultures juvéniles fortement subordonné au monde scolaire. Deux enquêtes menées dans l’académie du Limousin permettent de considérer les facteurs agissant sur les gouts des élèves : sexe, origine sociale, parcours scolaire. Si on perçoit chez une fraction non négligeable des filles lisant beaucoup une tendance à ne pas apprécier les livres lus en classe, les enseignants restent des prescripteurs importants de lecture. Les cultures juvéniles offrent certes des univers transmédiatiques susceptibles de favoriser le passage à la lecture, mais l’éclectisme des élèves se forme d’abord au contact des littératures légitimes. Or la lecture adolescente reste largement soumise aux origines sociales et subit la concurrence de nouvelles activités que soutiennent les sociabilités propres à cet âge. En ce sens, les lectures défendues par l’école permettent que les élèves disposent d’une ouverture au-delà des cultures juvéniles.
Fantasy et formation des sujets lecteurs au collège et au lycée
Authors: Olivier Isabelle 
Published: January 2020

Si les « mauvais genres » ont fait l’objet, déjà depuis les années 1980, de réflexions sur leur place en classe de français, il n’en va pas de même pour celui de la fantasy , en plein essor depuis une vingtaine d’années, depuis le succès de Harry Potter . Après avoir analysé les relations entre fantasy , cultures juvéniles et culture de masse, nous mettons en évidence la position ambivalente de l’institution scolaire par rapport au genre, en essayant d’en comprendre les raisons. Le potentiel didactique de la fantasy est alors interrogé, particulièrement en termes de lecture et de culture littéraires (approche des genres, de l’intertextualité, analyse d’images, immersion fictionnelle). In fine , il s’agit de montrer comment ce genre, réputé particulièrement immersif, pourrait néanmoins favoriser le développement d’authentiques postures de sujet-lecteur chez les élèves, au collège comme au lycée.
Investissements directs chinois en Asie du Sud-Est : une nouvelle dynamique au service d’une stratégie de puissance
Authors: Lafaye de Micheaux Elsa 
Published: January 2020

Au sein d’une région où la présence économique de la Chine a récemment changé d’échelle, décrire les investissements directs étrangers (IDE) chinois en Asie du Sud-Est ne va pas de soi malgré la disponibilité des sources. Cela paraît cependant nécessaire car les investissements à l’étranger entrent dans une stratégie et une dynamique de montée en puissance de la Chine, et ce depuis le début du xxi e siècle. En ASEAN, le rythme de leur progression est particulièrement rapide. L’analyse de la répartition spatiale et sectorielle de ces flux d’investissements directs montre que la logique industrielle et de développement croise et recouvre les dimensions politiques et géopolitiques d’une stratégie de puissance à l’échelle de la région.
L’alimentation : un nouvel enjeu pour les espaces ruraux
Authors: Delfosse Claire 
Published: January 2020

Cet article vise à explorer la question de l’alimentation en milieu rural. Il s’articule autour de deux points principaux : les ressources dont disposent les habitants et les stratégies qu’ils mobilisent pour se nourrir. Se nourrir en milieu rural revêt des spécificités liées à la faible densité, et aux questions de mobilité propres aux espaces ruraux. L’approvisionnement alimentaire y fait appel à des « formes anciennes » spécifiques qui se renouvellent et sont elles-mêmes support d’innovation, comme l’itinérance ou le jardinage. Les innovations portent sur de nouvelles formes d’agriculture et de distribution qui renouent avec la proximité. Elles révèlent également la multiplicité des initiatives en faveur du lien social en milieu rural.
Quelles coopérations entre les métropoles et les territoires ruraux en France ? Les pactes État-métropoles et l’expérimentation des contrats de réciprocité
Authors: Doré Gwénaël 
Published: January 2020

L’effet quasi mécanique d'entraînement du développement économique des métropoles sur leurs espaces environnants doit être nuancé : il doit être complété par la nécessité d'intégrer dans les stratégies de développement territorial la plus-value de l'espace rural pour l'attractivité et l'équilibre des cœurs urbains. Par conséquent, « la complémentarité entre ville centre et territoires périphériques doit être considérée non pas simplement comme une question de solidarité ex-post, de cohésion sociale et d'égalité devant les services publics », mais comme « une question stratégique pour le développement à moyen terme du territoire dans son ensemble » (Gilli, 2015). Ainsi les pactes État-métropoles signés en France à partir de la fin de 2016 comportent un volet de coopération métropolitaine et par ailleurs, six « contrats de réciprocité » ont été mis en place entre des métropoles et des territoires ruraux. Aussi, après avoir présenté le processus d’institutionnalisation des métropoles françaises et les relations de celles-ci avec leur hinterland, nous examinons la question de l'incitation à la coopération des métropoles avec les territoires alentour, notamment au travers des récents pactes État-métropoles, et enfin nous analysons les premiers contrats de réciprocité signés.
Semiochemical-mediated aggregation of the ambrosia beetle Trypodendron betulae (Coleoptera: Curculionidae: Scolytinae)
Authors: Kühnholz Susanne , Gries Regine , Borden John H. 
Published: January 2020

AbstractPorapak Q-captured volatiles from both sexes of Trypodendron betulae Swaine (Coleoptera: Curculionidae: Scolytinae) excised from newly attacked logs of paper birch, Betula papyrifera Marshall (Betulaceae), as well as volatiles from unattacked birch logs, were analysed by coupled gas chromatographic electroantennographic detection analysis. Active compounds were identified by gas chromatographic mass spectroscopy. The enantiomeric ratio of 6-ethenyl-2,2,6-trimethyloxan-3-ol (linalool oxide pyranoid) was determined using a Cyclodex B column. Field-trapping experiments disclosed that the female-produced aggregation pheromone of T. betulae is a blend of the (3S,6R)-trans- and (3R,6R)-cis-linalool oxide pyranoid. Trap catches were synergistically increased when the pheromone was combined with both the host volatile ethanol and with conophthorin, which was found in female beetles as well as host volatiles. Use of linalool oxide pyranoid reproductively isolates T. betulae from sympatric Trypodendron Stephens species for which only (+)-lineatin has been identified as an aggregation pheromone.
Monocyte-Derived Cells in Tissue-Resident Memory T Cell Formation
Authors: Chu Kuan-Lun , Batista Nathália V. , Girard Mélanie , Watts Tania H. 
Published: January 2020

Abstract
There is currently much interest in how different dendritic cell and macrophage populations contribute to T cell–mediated immunity. Although conventional dendritic cell subsets have received much attention for their role in T cell priming, there is emerging evidence for a role for monocyte-derived APC (MoAPC) in tissue-resident memory T cell (Trm) formation. Cells of the monocyte/macrophage lineage play a key role in providing chemokines and cytokines for the localization, differentiation, and survival of Trm and Trm precursors. In addition, inflammatory MoAPC are the key providers of TNF superfamily costimulatory signals, a signal we refer to as signal 4 for T cell activation. Recent evidence suggests that signal 4 from MoAPC occurs postpriming and substantially increases Trm formation. Key questions remain, such as the Ag dependence of signal 4 and the specific mechanisms by which MoAPC–Trm interactions affect the long-term maintenance of Trm.
Sex Differences in Ultrasound-Based Muscle Size and Mechanical Properties of the Cervical-Flexor and -Extensor Muscles
Authors: Nagai Takashi , Schilaty Nathan D. , Krause David A. , Crowley Eric M. , Hewett Timothy E. 
Published: January 2020

Context
Neck pain (NP), neck injuries, and concussions are more prevalent in female athletes than in their male counterparts. Females exhibit less neck girth, strength, and stiffness against a perturbation. As part of the clinical examination for individuals with NP, ultrasound (US)–based imaging of the cervical muscles has become common. Muscle size or thickness and stiffness can be measured with US-based B-mode and shear-wave elastography (SWE), respectively. Information on reliability, normative values, and sex differences based on US-based muscle size or thickness and stiffness in young and athletic individuals is limited.

Objective
To evaluate sex differences in US-based muscle size or thickness and biomechanical properties of the cervical-flexor and -extensor muscles.

Design
Cross-sectional study.

Setting
Laboratory.

Patients or Other Participants
A total of 13 women (age = 23.7 ± 1.9 years, height = 167.1 ± 6.1 cm, mass = 63.8 ± 5.6 kg) and 11 men (age = 25.6 ± 4.9 years, height = 178.7 ± 8.3 cm, mass = 78.9 ± 12.0 kg).

Main Outcome Measure(s)
The same examiner collected all measures, using US B-mode to scan the cross-sectional area and thickness of the longus colli (LC), sternocleidomastoid (SCM), cervical-extensor muscles, and upper trapezius (UT) muscle. The US SWE-mode was used to measure the stiffness of the SCM and UT. Independent t tests or Mann-Whitney U tests were calculated to determine sex differences. The intraclass correlation coefficient (ICC) measured intrarater test-retest reliability.

Results
Men had thicker SCMs than women (P = .01). No sex differences were present for longus colli cross-sectional area, cervical-extensor muscle thickness, or UT thickness (P &gt; .05). In addition, no sex differences were evident for SCM (P = .302) or UT (P = .703) SWE stiffness. Reliability was good to excellent (ICC = 0.715–0.890) except for SCM SWE stiffness (ICC = 0.554).

Conclusions
The only sex difference was in SCM thickness. However, smaller SCMs in women did not result in less SCM SWE stiffness. We provided normative values for US-based imaging of the cervical-flexor and -extensor muscles in young and athletic men and women.
Effect of legume intercropping on N2O emissions and CH4 uptake during maize production in the Great Rift Valley, Ethiopia
Authors: Raji Shimelis Gizachew , Dörsch Peter 
Published: January 2020

Abstract. Intercropping with legumes is an important component of climate-smart
agriculture (CSA) in sub-Saharan Africa, but little is known about its
effect on soil greenhouse gas (GHG) exchange. A field experiment was
established at Hawassa in the Ethiopian rift valley, comparing nitrous oxide
(N2O) and methane (CH4) fluxes in minerally fertilized maize (64 kg N ha−1) with and without Crotalaria (C. juncea) or lablab (L. purpureus) as intercrops
over two growing seasons. To study the effect of intercropping time,
intercrops were sown either 3 or 6 weeks after maize. The legumes were
harvested at flowering, and half of the aboveground biomass was mulched. In
the first season, cumulative N2O emissions were largest in 3-week
lablab, with all other treatments being equal to or lower than the fertilized
maize mono-crop. After reducing mineral N input to intercropped systems by
50 % in the second season, N2O emissions were comparable with the
fully fertilized control. Maize-yield-scaled N2O emissions in the first
season increased linearly with aboveground legume N yield (p=0.01), but
not in the second season when early rains resulted in less legume biomass
because of shading by maize. Growing-season N2O-N emission factors
varied from 0.02 % to 0.25 % in 2015 and 0.11 % to 0.20 % in 2016 of the
estimated total N input. Growing-season CH4 uptake ranged from 1.0 to
1.5 kg CH4-C ha−1, with no significant differences between
treatments or years but setting off the N2O-associated emissions by up
to 69 %. Our results suggest that leguminous intercrops may increase
N2O emissions when developing large biomass in dry years but, when
mulched, can replace part of the fertilizer N in normal years, thus
supporting CSA goals while intensifying crop production in the region.
Entre “lava-pés” e “lava-mãos”: valores, hierarquias e poder aristocrático nas baladas elitizadas
Authors: Da Conceição Daniel Machado , Vaz Alexandre Fernandez 
Published: January 2020

Uma postagem repercutiu nas redes sociais, fato que aconteceu na cidade de Florianópolis/SC, durante a temporada de verão 2018. Um vídeo mostra a figura de um milionário, assíduo frequentador dos famosos beach clubs, o qual comprou algumas garrafas de champanhe e utilizou seu líquido para lavar os pés sujos com areia da praia. Ao propor um comentário sobre o vídeo, o texto pretende desvelar parte das relações que são produzidas no espaço das baladas e que representam um manto aristocrático que encobre interesses e privilégios de uma classe que se reconhece como “nobre”. No esforço para elaborar a interpretação proposta, as expressões “lava-pés” e “lava-mãos” serão articuladas para uma melhor apresentação dos argumentos. Podemos destacar que ambas ações presentes nas baladas – “lava-pés” e “lava-mãos” - são promotoras dos valores aristocráticos tão presentes em nossa sociedade brasileira. Independente se o primeiro tem sentido de obrigação para a elite do dinheiro e o segundo de um servilismo voluntário na atitude dos serviçais.
Effect of Accelerated Ageing on the Ballistic Resistance of Hybrid Composite Armour with Advanced Ceramics and UHMWPE Fibers
Authors: Fejdyś Marzena , Kucharska-Jastrząbek Agnieszka , Kośla Katarzyna 
Published: January 2020

The main objective of this complex study was to evaluate the durability of newly developed ballistic inserts designed using ultra-high-molecular-weight polyethylene (UHMWPE) fibres and advanced ceramics (Al2O3 or SiC). The forecasting of changes in the properties of the newly developed ballistic system is related to safe use and reliable construction, and requires ageing tests to be carried out in natural conditions. Due to the length of this process, a program of tests was developed for simulated use of the composite ballistic inserts under conditions of accelerated ageing, taking into account the 6-year lifespan of these products, which is in accordance with the PN-V-87000:2011 standard. As part of the research work, the new ballistic inserts were tested, and also ones subjected to laboratory ageing for 50, 100, 150 days, which corresponded to 2.2, 4.3 & 6.5 years of ageing in real conditions. The samples selected were verified in terms of ballistic and mechanical behaviour as well as changes in their chemical structure. Changes in the microstructure of the ballistic materials were evaluated using DSC analysis as well as infrared spectroscopy (FTIR-ATR).

Published: January 2020

Corporate Social Responsibility (CSR) has captured great attention and importance in recent years, particularly in the clothing industry. Currently, in order to respond to market requirements, clothing companies are increasing their focus on aspects related to production, working conditions and respect for human rights. The paper examines selected Polish and British clothing companies through the prism of CSR implementation in their business practices. The research objective of the paper is the assessment of the state of CSR advancement in Polish and British clothing companies. The paper presents the results of a qualitative study based on semi-structured interviews with mid-level managers of these companies. The empirical study described in this paper shows how social responsibility is understood by the representatives of Polish and British clothing companies, what kind of CSR activities are pursued by these companies, and how they benefit from these activities.
Treatment of Industrial Textile Wastewater in Biological Aerated Filters – Microbial Diversity Analysis
Authors: Paździor Katarzyna , Wrębiak Julita , Ledakowicz Stanisław 
Published: January 2020

Investigated herein was the biodegradation of highly contaminated textile wastewater on a laboratory scale, with biological aerobic filters as a single treatment and in combination with the coagulation/flocculation process. Among the three support materials tested (Intalox saddles, ceramsite and beach shavings), the highest organic carbon compound removals (above 60% measured as COD and TOC) and steady operation were obtained for ceramsite. Effective and stable biological treatment was possible thanks to the development of biofilm of high bacterial and fungal diversity. The biodiversity of microflora was estimated on the basis of metagenomic analysis. The coagulation process with PAX 18 was effective in total phosphorus depletion (94%), while the coagulant Epoly CRD enabled up to 99% colour removal. The best results were obtained after the combined treatment, in which biodegradation was followed by coagulation (PAX 18). Such a combination enabled the removal of 98% of BOD5, 87% of COD, 88% of TOC, 48% of the total nitrogen, 98% of the total phosphorus, 98% of toxicity (towards Vibrio fisheri) and above 81% of colour.
