Published: May 2019

The data presented here come from field observations of Aves between August 2013 and October 2018 as part of a LIFE research project aiming to preserve and restore three coastal wetlands from Praia da Vitória (Terceira Island, Azores, Portugal). Systematic monthly observations were carried out for five years in order to provide a checklist and monitoring of bird species and subspecies observed in three sites: Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP). Main objectives were to determine their ornithological richness while also adding data to the overall knowledge of Azorean Avifauna and to monitor seasonal and between-year variation on species abundance.During a five-year observation period (2013-2018), a total of 82,985 birds belonging to 108 species/subspecies were observed. From this, 16,663 were in PPV, 11,793 from PBJ and 54,529 from PPCP. The total richness was 55, 40 and 85, respectively. Three species are first records for the Azores:Aythyaamericana(Eyton, 1838);Chlidoniasleucopterus(Temminck, 1815) andTringabrevipes(Vieillot, 1816). One species is a new record for Terceira Island:Lophodytescucullatus(Linnaeus, 1758).
De la démocratie à la démocrature familiale en Afrique
Authors: Glaser Antoine 
Published: May 2019

La guerre froide a longtemps gelé tout processus démocratique en Afrique, y compris dans les pays où des Africains ont libéré leurs pays, les armes à la main. À la chute du mur de Berlin, le vent démocratique de l’Est a soufflé timidement et tardivement vers le Sud. Dans les années 1990, des conférences nationales souveraines ont semblé ébranler les palais d’autocrates souvent cooptés ou adoubés au pouvoir par les anciennes puissances coloniales. Un leurre. Non seulement les présidents « sortants » ont repris la main, mais les plus anciens au pouvoir ont verrouillé toute alternance en ayant appris à jongler avec des constitutions importées. D’autres ont dû affronter l’opposition de leurs anciens compagnons de route, soutenus par des sociétés civiles de mieux en mieux organisées et informées grâce aux réseaux sociaux. La vraie nouveauté est la montée en puissance d’une jeunesse urbanisée et mondialisée en phase avec des diasporas très politisées.
Caricature d’un enseignant d’EPS dans les années 1980 : P.R.O.F.S. de Patrick Schulmann (1985)
Authors: Bauer Thomas , Lemonnier Jean-Marc 
Published: May 2019

Cet article propose d’étudier la caricature de l’enseignant d’éducation physique et sportive dans le film P.R.O.F.S. de Patrick Schulmann (1985) en partant du principe que le film constitue une sorte « d’arrêt sur image » – et donc une source de renseignements utiles – sur l’enseignement de l’époque et la façon dont il était parfois perçu. Il semble que deux lectures, à la fois distinctes et complémentaires, soient possibles. La première, celle du grand public, renvoie à la comédie à proprement parler où la figure stéréotypée du « prof de sport » est réduite à sa dimension humoristique – ce dernier étant alors un marginal dans la « maison École ». La seconde, celle des initiés et acteurs de la corporation, révèle un personnage qui participe de l’évolution de son statut et de sa discipline en cherchant, par exemple, à moderniser ses contenus d’enseignement. C’est en mettant en tension ces deux lectures que le film représente un réel « marqueur » de son temps et un outil original pour (ré)interroger l’histoire de l’éducation physique scolaire.
Claude Vigée : exil des langues sous la « lune d’hiver »
Authors: Lerousseau Andrée 
Published: May 2019

Après un rappel des « errances du langage », du premier exil hors de la langue maternelle, le dialecte alsacien, à l’apprentissage de l’hébreu, la langue originelle, à quarante ans, nous nous attarderons sous « la lune d’hiver », la longue période d’exil aux États-Unis, où s’affirme le choix de Claude Vigée de faire du français sa langue d’écriture. Période d’hibernation, mais également de germination, l’exil américain voit naître la langue du poème, fécondée au « jeu des langues » qui l’encadrent, imprégnée de la saveur et de la présence charnelle des choses héritées de la langue maternelle, et pénétrée déjà, avant même le « grand retour » sur la terre des ancêtres, du « mystère d’Israël ».
L’exil de la langue. Le poète Günter Kunert entre Est et Ouest
Authors: Benoit Martine 
Published: May 2019

Considéré en Allemagne comme un des écrivains dissidents les plus intègres et les plus courageux de l’ancienne R.D.A., Günter Kunert s’interroge et nous interroge sur ce que signifie qu’être un poète de langue allemande d’origine juive après Auschwitz. Un double mouvement se fait jour dans l’écriture de Günter Kunert : d’une part, son désir de s’inscrire dans une tradition littéraire allemande dont il interroge les codes d’écriture et les compromissions ; d’autre part, son attention permanente à inscrire au cœur de son écriture la mise en garde et d’affirmer la poésie comme acte de résistance à l’histoire et à l’époque. C’est de ce double mouvement dont témoigne cet article.

AbstractIFN belong to a group of cytokines specialized in the immunity to viruses. Upon viral infection, type I IFN is produced and alters the transcriptome of responding cells through induction of a set of IFN stimulated genes (ISGs) with regulatory or antiviral function, resulting in a cellular antiviral state. Fish genomes have both type I IFN and type II IFN (IFN-γ), but no type III (λ) IFN has been identified. Their receptors are not simple counterparts of the mammalian type I/II IFN receptors, because alternative chains are used in type I IFN receptors. The mechanisms of the downstream signaling remain partly undefined. In mammals, members of the signal transducer and activator of family of transcription factors are responsible for the transmission of the signal from cytokine receptors, and STAT2 is required for type I but not type II IFN signaling. In fish, its role in IFN signaling in fish remains unclear. We isolated a Chinook salmon (Oncorhynchus tshawytscha) cell line, GS2, with a stat2 gene knocked out by CRISPR/Cas9 genome editing. In this cell line, the induction of ISGs by stimulation with a recombinant type I IFN is completely obliterated as evidenced by comparative RNA-seq analysis of the transcriptome of GS2 and its parental counterpart, EC. Despite a complete absence of ISGs induction, the GS2 cell line has a remarkable ability to resist to viral infections. Therefore, other STAT2-independent pathways may be induced by the viral infection, illustrating the robustness and redundancy of the innate antiviral defenses in fish.

Published: May 2019

Background and Objectives:
Nowadays, more and more open source medical imaging databases are published on the Internet for medical teaching, algorithm development, and medical research. However, a statistical survey of these databases is still lacking. In this survey, we summarize the current status of open source medical image databases on the Internet. The aim is to make it easier for everyone to find and use open source medical image data.

Methods:
Information about publicly available medical image databases was collected by searching for scientific papers and Internet search engines. Based on the collected information, the number of databases and the number of images were counted for different diseases, body parts, imaging modalities, and countries.

Results:
Cancer, particularly breast cancer and lung cancer, ranked top in database numbers among all diseases. The breast, brain, lung, and chest are the top four body parts in terms of database numbers. Computed tomography, magnetic resonance imaging, and X-ray are the most common imaging modalities in the open source datasets. The USA and the Netherlands are the top two countries who own the most databases.

Conclusions:
The rankings for diseases and body parts were closely related to the diseases morbidity and the health-care expenditure of a country. The number of open sources of medical imaging databases is still growing; there is a need for continuous statistical research on their existence status in the coming years. The list of all the collected databases is opened on the Internet (https://docs.qq.com/sheet/DQWF0QlZKVHpHU1Za).
Developing serious games to improve children’s compliance in chronic illnesses: Input from two use cases
Authors: Morganti Luca , Ascolese Antonio , Zettl Annabel , Pannese Lucia 
Published: May 2019

Background and Objectives:
Developing serious games (SGs) for children is challenging, especially when dealing with complex medical diagnosis. Enhancing children’s compliance for the treatment of chronic conditions is a crucial challenge that requires caring about the engagement of users in the game experience already from the initial stages of the development.

Materials and Methods:
Participatory design is the methodological key to trace the right path toward an effective and easy-to-use game; specific methodological settings are necessary to collect meaningful feedback and guide the creation of the game. Our article reports the involvement of 14 young users in two different stages of the design and development of two SGs for chronic clinical conditions (Crohn’s disease and cystic fibrosis).

Results:
Specific feedbacks were reported about game contents (e.g., the preference for anthropomorphic avatars) and technological issues (e.g., the need of a graphical tutorial).

Conclusions:
Using the same methodological approach in two different phases of the development allows to highlight children’s perspective toward a technological solution addressing clinical compliance.

Abstract. The objective of this study was to evaluate the impact of a low metabolizable energy (low-ME) diet supplemented with a multienzyme blend (KEMZYME®) on the growth performance, carcass traits and meat quality of chickens. A total of 108 broiler chicks (Ross 308) were randomly allocated to three experimental groups with six replicates per treatment and five birds per replicate; the groups were treated as follows: a control diet with no additive and standard metabolizable energy (ME; 3200 kcal kg−1); a low metabolizable energy (low-ME; 3000 kcal kg−1) diet; and a low-ME diet + 0.5 g kg−1 diet of enzyme (low-ME–Enz). Live body weight (LBW) at 43 and 47 d and body weight gain (BWG) during the periods from 38 to 43, 43 to 47 and 33 to 47 d decreased with the low-ME and low-ME–Enz diets in comparison with the control-diet (p<0.05). The values of the feed conversion ratio (FCR) were significantly increased with low-ME diets with or without enzyme at all growing stages. There were no significant differences among treatments in terms of carcass traits. With the exception of the jejunum weight, dietary treatments did not affect any digestive tract segments. Meat hardness decreased with the low-ME–Enz diet compared with the other diets (P=0.039). Meat yellowness of the breast muscle increased (P=0.001) with the low-ME–Enz diet in comparison with the other treatments at 24 h post-slaughter. In conclusion, the low-ME diet supplemented with KEMZYME® did not influence most of performance parameters and carcass traits of chickens; however, adding enzymes to the low-ME diet is an effective strategy to improve the meat quality criteria and small intestine characteristics.
Evaluation of the WRF lake module (v1.0) and its improvements at a deep reservoir

Published: May 2019

Abstract. Large lakes and reservoirs play important roles in modulating regional
hydrological cycles and climate; however, their representations in coupled
models remain uncertain. The existing lake module in the Weather Research and
Forecasting (WRF) system (hereafter WRF-Lake), although widely used, did not
accurately predict temperature profiles in deep lakes mainly due to its poor
lake surface property parameterizations and underestimation of heat transfer
between lake layers. We therefore revised WRF-Lake by improving its
(1) numerical discretization scheme; (2) surface property parameterization;
(3) diffusivity parameterization for deep lakes; and (4) convection scheme,
the outcome of which became WRF-rLake (i.e., revised lake model). We
evaluated the off-line WRF-rLake by comparing simulated and measured water
temperature at the Nuozhadu Reservoir, a deep reservoir in southwestern
China. WRF-rLake performs better than its predecessor by reducing the
root-mean-square error (RMSE) against observed lake surface temperatures
(LSTs) from 1.4 to 1.1 ∘C and consistently improving simulated
vertical temperature profiles. We also evaluated the sensitivity of simulated
water temperature and surface energy fluxes to various modeled lake
processes. We found (1) large changes in surface energy balance fluxes (up to
60 W m−2) associated with the improved surface property
parameterization and (2) that the simulated lake thermal structure depends
strongly on the light extinction coefficient and vertical diffusivity.
Although currently only evaluated at the Nuozhadu Reservoir, we expect that
these model parameterization and structural improvements could be general and
therefore recommend further testing at other deep lakes and reservoirs.
Zooplankton diel vertical migration in the Corsica Channel (north-western Mediterranean Sea) detected by a moored acoustic Doppler current profiler

Published: May 2019

Abstract. Diel vertical migration (DVM) is a survival strategy adopted by zooplankton
that we investigated in the Corsica Channel using acoustic Doppler current profiler (ADCP) data from April 2014
to November 2016. The principal aim of the study is to characterize migration
patterns and biomass temporal evolution of zooplankton along the water
column. The ADCP measured vertical velocity and echo intensity in the water
column range between about 70 and 390 m (the bottom depth is 443 m). During
the investigated period, zooplanktonic biomass had a well-defined daily and
seasonal cycle, with peaks occurring in late winter to spring (2015 and
2016) when the stratification of the water column is weaker. Zooplanktonic
biomass temporal distribution in the whole water column is well correlated
with biomass of primary producers, estimated with satellite data.
Zooplanktonic blooming and non-blooming periods have been identified and
studied separately. During the non-blooming period zooplanktonic biomass was
most abundant in the upper and the deep layers, while during the blooming
period the upper-layer maximum in zooplanktonic biomass disappeared and the
deep layer with high zooplanktonic biomass became thicker. These two layers
are likely to correspond to two different zooplanktonic communities. The
evolution of zooplanktonic biomass is well correlated with chlorophyll, with
phytoplankton biomass peaks preceding the upper-layer secondary production by
a lag of about 3.5 weeks. Nocturnal DVM appears to be the main
pattern during both periods, but reverse and twilight migration are also
detected. Nocturnal DVM was more evident at mid-water than in the deep and
the upper layers. DVM occurred with different intensities during blooming and
non-blooming periods. One of the main outcomes is that the principal drivers
for DVM are light intensity and stratification, but other factors, like
the moon cycle and primary production, are also taken in consideration.
A dimensão simbólica do consumo e o mercado como construção social: um estudo sobre a compra da casa e de produtos de moda

Published: May 2019

Estudos sobre a dimensão simbólica do consumo e o conceito de mercado como construção social são temas abordadas por duas pesquisas que, mesmo realizadas de maneira autônomas e com temáticas diferentes, apresentam convergência nas análises. O objetivo deste artigo, portanto, é refletir sobre essas convergências, sendo a primeira pesquisa sobre a compra da casa própria a partir do programa habitacional federal, Minha Casa Minha Vida; e a segunda pesquisa acerca do consumo de marcas de moda globais em comunidades de baixa renda. Ambas as pesquisas discutem as relações sociais que se instauram em torno da compra destes bens, os discursos racionais da motivação da compra e o consumo como ato social e simbólico.

Published: May 2019

The main purpose of this study was to identify the existing relationship between character strengths and life satisfaction, as well as some sociodemographic aspects related to gender differences. Both the Virtue and Strength Inventory (IVYF; Cosentino & Castro, 2008) and the Satisfaction with Life Scale (SWLS; Diener, Emmons, Larsen & Griffin, 1985) were administered to 343 undergraduate students whose primary major of study pertained to health professions. Results indicated that for women, love and gratitude are the strengths that explained 21.3 % of the variance regarding satisfaction with life, while love and social intelligence predicted 44.5 % of life satisfaction for men. Results are discussed under the light of cultural differences.

Published: May 2019

BackgroundCultivars of bahiagrass (Paspalum notatumFlüggé) are widely used for pasture in the Southeastern USA. Soil microbial communities are unexplored in bahiagrass and they may be cultivar-dependent, as previously proven for other grass species. Understanding the influence of cultivar selection on soil microbial communities is crucial as microbiome taxa have repeatedly been shown to be directly linked to plant performance.ObjectivesThis study aimed to determine whether different bahiagrass cultivars interactively influence soil bacterial and fungal communities.MethodsSix bahiagrass cultivars (‘Argentine’, ‘Pensacola’, ‘Sand Mountain’, ‘Tifton 9’, ‘TifQuik’, and ‘UF-Riata’) were grown in a randomized complete block design with four replicate plots of 4.6 × 1.8 m per cultivar in a Rhodic Kandiudults soil in Northwest Florida, USA. Three soil subsamples per replicate plot were randomly collected. Soil DNA was extracted and bacterial 16S ribosomal RNA and fungal ribosomal internal transcribed spacer 1 genes were amplified and sequenced with one Illumina Miseq Nano.ResultsThe soil bacterial and fungal community across bahiagrass cultivars showed similarities with communities recovered from other grassland ecosystems. Few differences in community composition and diversity of soil bacteria among cultivars were detected; none were detected for soil fungi. The relative abundance of sequences assigned to nitrite-oxidizingNitrospirawas greater under ‘Sand Mountain’ than ‘UF-Riata’. Indicator species analysis revealed that several bacterial and fungal indicators associated with either a single cultivar or a combination of cultivars are likely to be plant pathogens or antagonists.ConclusionsOur results suggest a low impact of plant cultivar choice on the soil bacterial community composition, whereas the soil fungal community was unaffected. Shifts in the relative abundance ofNitrospiramembers in response to cultivar choice may have implications for soil N dynamics. The cultivars associated with presumptive plant pathogens or antagonists indicates that the ability of bahiagrass to control plant pathogens may be cultivar-dependent, however, physiological studies on plant-microbe interactions are required to confirm this presumption. We therefore suggest that future studies should explore the potential of different bahiagrass cultivars on plant pathogen control, particularly in sod-based crop rotation.
