L'alimentation des coléoptères saproxyliques et notes sur les contenus stomacaux de cinq espèces
Authors: Dodelin Benoît , Pene Benjamin , André Jean 
Published: March 2017

Les différents groupes fonctionnels et guildes dont relèvent les coléoptères saproxyliques sont présentés. La nomenclature est détaillée et les groupes écologiques sont replacés les uns par rapports aux autres dans les habitats que produit le bois mort ou en décomposition.
L'analyse en microscopie optique des contenus stomacaux d'adultes de Mycetoma suturale (Panzer), Serropalpus barbatus (Schallenberg) (Melandryidae) et Triplax rufipes (Fabricius) (Erotylidae) nous a permis de mettre en évidence l'ingestion de champignons chez M. suturale et T. rufipes. Des levures stomacales sont observées chez S. barbatus et T. rufipes. Aucune matière ligneuse n'a pu être décelée chez S. barbatus dont les larves vivent dans le bois de résineux en décomposition. Enfin, pour les deux Eucnemidae étudiés -Hylis olexai (Palm) et Xylophilus corticalis (Paykull) -, le tube digestif n'a pu être mis en évidence par dissection. Il est probable que celui-ci soit très fin, fragile et dégradé par les liquides de conservation plutôt que véritablement absent.

Magnetoacoustic Waves in a Stratified Atmosphere with a Magnetic Null Point
Authors: Tarr Lucas A. , Linton Mark , Leake James 
Published: March 2017

Abstract
We perform nonlinear MHD simulations to study the propagation of magnetoacoustic waves from the photosphere to the low corona. We focus on a 2D system with a gravitationally stratified atmosphere and three photospheric concentrations of magnetic flux that produce a magnetic null point with a magnetic dome topology. We find that a single wavepacket introduced at the lower boundary splits into multiple secondary wavepackets. A portion of the packet refracts toward the null owing to the varying Alfvén speed. Waves incident on the equipartition contour surrounding the null, where the sound and Alfvén speeds coincide, partially transmit, reflect, and mode-convert between branches of the local dispersion relation. Approximately 15.5% of the wavepacket’s initial energy (E
input) converges on the null, mostly as a fast magnetoacoustic wave. Conversion is very efficient: 70% of the energy incident on the null is converted to slow modes propagating away from the null, 7% leaves as a fast wave, and the remaining 23% (0.036E
input) is locally dissipated. The acoustic energy leaving the null is strongly concentrated along field lines near each of the null’s four separatrices. The portion of the wavepacket that refracts toward the null, and the amount of current accumulation, depends on the vertical and horizontal wavenumbers and the centroid position of the wavepacket as it crosses the photosphere. Regions that refract toward or away from the null do not simply coincide with regions of open versus closed magnetic field or regions of particular field orientation. We also model wavepacket propagation using a WKB method and find that it agrees qualitatively, though not quantitatively, with the results of the numerical simulation.
Politiques et sciences sociales de la vieillesse en France (1962-2016) : de la retraite à la dépendance
Authors: Weber Florence 
Published: March 2017

Comment comprendre la difficulté des sciences sociales françaises à s’emparer du thème de la vieillesse, alors même que la société française est confrontée à la question démographique et économique du vieillissement de la population depuis les années 1990 ? Ce constat, fondé sur une revue de littérature, révèle les difficultés des politiques sociales françaises à combiner retraites, lutte contre la pauvreté et professionnalisation de la prise en charge. Depuis 1962 et le rapport Laroque, deux approches de la vieillesse se sont succédé sans discontinuité apparente. Après une période centrée sur la pauvreté et l’isolement des retraités ayant peu cotisé, les sociologues se sont reconvertis au cours des années 1980 dans l’étude des pathologies invalidantes du grand âge, en lien avec la gériatrie. La canicule de 2003, et l’abandon des corps des défunts parisiens, met en évidence la myopie du débat public en France qui tarde à prendre la mesure d’une situation climatique exceptionnelle et à s’appuyer sur la complémentarité entre aide familiale, voisinage et aide professionnelle.
L’échec de Hollande sur l’écologie est aussi celui d’EELV
Authors: Farbiaz Patrick 
Published: March 2017

Énergie, agriculture, climat, infrastructures, etc. : en matière d’écologie, les renoncements et les reculs auront été nombreux sous le quinquennat de François Hollande. Si ce bilan est sombre, il appartient également à Europe Ecologie Les Verts (EELV) qui y a participé pendant les deux premières années, avant de s’isoler sur la scène nationale et de subir plusieurs revers électoraux. Patrick Farbiaz dresse un tableau sans concession de la crise de l’écologie politique, dont les racines sont toutefois plus anciennes. Désormais au pied du mur, l’écologie politique se trouve enjointe à repenser son orientation stratégique, son ancrage social et son positionnement au sein de la gauche post-croissance.
Podemos : l’irruption d’un nouveau parti politique en Espagne
Authors: Nez Héloïse 
Published: March 2017

Podemos est un phénomène à la fois récent et en pleine expansion : ce parti qui a émergé il y a trois ans en Espagne, dans la foulée du mouvement des Indignés, est aujourd’hui l’un des principaux acteurs de la scène politique nationale. Il est également devenu un référent de la gauche anti-austérité en Europe. Cet article revient sur les origines de Podemos pour comprendre l’émergence d’un nouveau parti politique sur le continent européen. Il souligne la spécificité du contexte de crise à l’échelle nationale, interroge les relations avec le mouvement des Indignés et s’intéresse aux trajectoires et références des fondateurs du parti.
L’antiracisme politique et la gauche : une alliance possible ?

Alcir, l’Association de Lutte contre l’Islamophobie et les Racismes de Paris 20, organisait le 21 septembre 2016 son meeting « Pour un Printemps de la liberté, de l’égalité, de la fraternité », en riposte contre le « Printemps républicain », courant laïciste et islamophobe composé essentiellement de personnalités du PS. Lancé le 14 juillet, l’appel « Agir contre l’islamophobie et les racismes » interpellait toute la gauche sur les conditions d’une alliance. Alors que les discours islamophobes des politiques s’intensifient en cette année électorale, aucun parti ne semble s’en inquiéter, tandis que le mouvement antiraciste politique est divisé sur cette question : une alliance est-elle possible avec la gauche ? Et si oui, à quelles conditions ? Trois membres d’Alcir tentent de poser les termes du débat.

Abstract
The development of rheumatoid arthritis (RA) is linked to functional changes in synovial fibroblasts (SF) and local infiltration of T lymphocytes. Fibroblasts possess the capacity to suppress T cell responses, although the molecular mechanisms of this suppression remain incompletely understood. In this study, we aimed to define the mechanisms by which noninflammatory SF modulate Th cell responses and to determine the immunosuppressive efficacy of RASF. Hence, the influence of SF from osteoarthritis or RA patients on total Th cells or different Th cell subsets of healthy donors was analyzed in vitro. We show that SF strongly suppressed the proliferation of Th cells and the secretion of IFN-γ in a cell contact–independent manner. In cocultures of SF and Th cells, tryptophan was completely depleted within a few days, resulting in eukaryotic initiation factor 2α phosphorylation, TCRζ-chain downregulation, and proliferation arrest. Blocking IDO1 activity completely restored Th cell proliferation, but not IFN-γ production. Interestingly, only the proliferation of Th1 cells, but not of Th2 or Th17 cells, was affected. Finally, RASF had a significantly lower IDO1 expression and a weaker Th cell suppressive capacity compared with osteoarthritis SF. We postulate that the suppression of Th cell growth by SF through tryptophan catabolism may play an important role in preventing inappropriate Th cell responses under normal conditions. However, expansion of Th17 cells that do not induce IDO1-mediated suppression and the reduced capacity of RASF to restrict Th cell proliferation through tryptophan metabolism may support the initiation and propagation of synovitis in RA patients.
The Lower Limit of Regulatory CD4+ Foxp3+ TCRβ Repertoire Diversity Required To Control Autoimmunity

Published: March 2017

Abstract
The TCR repertoire of regulatory T cells (Tregs) is highly diverse. The relevance of this diversity to maintain self-tolerance remains unknown. We established a model where the TCR repertoire of normal polyclonal Tregs was limited by serial transfers into IL-2Rβ−/− mice, which lack functional Tregs. After a primary transfer, the donor Treg TCR repertoire was substantially narrowed, yet the recipients remained autoimmune-free. Importantly, upon purification and transfer of donor-derived Tregs from an individual primary recipient into neonatal IL-2Rβ−/− mice, the secondary recipients developed autoimmunity. In this study, the Treg TCRβ repertoire was reshaped and further narrowed. In contrast, secondary IL-2Rβ recipients showed fewer symptoms of autoimmunity when they received donor Tregs that were premixed from several primary recipients to increase their TCRβ repertoire diversity. About 8–11% of the Treg TCRβ repertoire was estimated to be the minimum required to establish and maintain tolerance in primary IL-2Rβ−/− recipients. Collectively, these data quantify where limitations imposed on the Treg TCRβ repertoire results in a population of Tregs that cannot fully suppress polyclonal autoreactive T cells. Our data favor a model where the high diversity of the Treg TCR provides a mechanism for Tregs to actively adapt and effectively suppress autoreactive T cells, which are not fixed, but are evolving as they encounter self-antigens.
Computer-aided Detection Fidelity of Pulmonary Nodules in Chest Radiograph
Authors: Dellios Nikolaos , Teichgraeber Ulf , Chelaru Robert , Malich Ansgar , Papageorgiou Ismini E 
Published: March 2017

Aim:
The most ubiquitous chest diagnostic method is the chest radiograph. A common radiographic finding, quite often incidental, is the nodular pulmonary lesion. The detection of small lesions out of complex parenchymal structure is a daily clinical challenge. In this study, we investigate the efficacy of the computer-aided detection (CAD) software package SoftView™ 2.4A for bone suppression and OnGuard™ 5.2 (Riverain Technologies, Miamisburg, OH, USA) for automated detection of pulmonary nodules in chest radiographs.

Subjects and Methods:
We retrospectively evaluated a dataset of 100 posteroanterior chest radiographs with pulmonary nodular lesions ranging from 5 to 85 mm. All nodules were confirmed with a consecutive computed tomography scan and histologically classified as 75% malignant. The number of detected lesions by observation in unprocessed images was compared to the number and dignity of CAD-detected lesions in bone-suppressed images (BSIs).

Results:
SoftView™ BSI does not affect the objective lesion-to-background contrast. OnGuard™ has a stand-alone sensitivity of 62% and specificity of 58% for nodular lesion detection in chest radiographs. The false positive rate is 0.88/image and the false negative (FN) rate is 0.35/image. From the true positive lesions, 20% were proven benign and 80% were malignant. FN lesions were 47% benign and 53% malignant.

Conclusion:
We conclude that CAD does not qualify for a stand-alone standard of diagnosis. The use of CAD accompanied with a critical radiological assessment of the software suggested pattern appears more realistic. Accordingly, it is essential to focus on studies assessing the quality-time-cost profile of real-time (as opposed to retrospective) CAD implementation in clinical diagnostics.
Accountability y culturas periodísticas en España. Impacto y propuesta de buenas prácticas en los medios de comunicación españoles’ (MediaACES)
Authors: Suárez-Villegas Juan Carlos , Rodríguez-Martínez Ruth , Mauri-Ríos Marcel , López-Meri Amparo 
Published: March 2017

La responsabilidad de los medios de comunicación y de los profesionales de la información ha de expresarse a través de mecanismos de rendición de cuentas (media accountability) que permitan conocer el grado de cumplimiento de valores como el pluralismo, la transparencia y la veracidad informativa. Este proyecto busca detectar las culturas periodísticas existentes en distintas comunidades autónomas de España, y examinar el impacto de los instrumentos de rendición de cuentas o media accountability systems en cada territorio. El trabajo parte de la hipótesis de que la cultura periodística en España no responde a un único modelo de sistema de medios (modelo mediterráneo o pluralista polarizado), como señalan Hallin y Mancini en Comparing Media Systems, sino que la diversidad de culturas periodísticas requiere matizar esta clasificación. La metodología combina la técnica de la encuesta online a diferentes actores mediáticos y diversos focus group con expertos, responsable de medios y ciudadanos. Los resultados permitirán diseñar y proporcionar a los medios modelos de evaluación de rendición de cuentas que integren valores como la transparencia y la pluralidad.

Abstract. A 1-year inter-comparison of classical and modern radiation and sunshine duration (SD) instruments has been performed at Izaña Atmospheric Observatory (IZO) located in Tenerife (Canary Islands, Spain) starting on 17 July 2014. We compare daily global solar radiation (GSRH) records measured with a Kipp &amp; Zonen CM-21 pyranometer, taken in the framework of the Baseline Surface Radiation Network, with those measured with a multifilter rotating shadowband radiometer (MFRSR), a bimetallic pyranometer (PYR) and GSRH estimated from sunshine duration performed by a Campbell–Stokes sunshine recorder (CS) and a Kipp &amp; Zonen sunshine duration sensor (CSD). Given that the BSRN GSRH records passed strict quality controls (based on principles of physical limits and comparison with the LibRadtran model), they have been used as reference in the inter-comparison study. We obtain an overall root mean square error (RMSE) of  ∼  0.9 MJm−2 (4 %) for PYR and MFRSR GSRH, 1.9 (7 %) and 1.2 MJm−2 (5 %) for CS and CSD GSRH, respectively. Factors such as temperature, relative humidity (RH) and the solar zenith angle (SZA) have been shown to moderately affect the GSRH observations. As an application of the methodology developed in this work, we have re-evaluated the GSRH data time series obtained at IZO with two PYRs between 1977 and 1991. Their high consistency and temporal stability have been proved by comparing with GSRH estimates obtained from SD observations. These results demonstrate that (1) the continuous-basis inter-comparison of different GSRH techniques offers important diagnostics for identifying inconsistencies between GSRH data records, and (2) the GSRH measurements performed with classical and more simple instruments are consistent with more modern techniques and, thus, valid to recover GSRH data time series and complete worldwide distributed GSRH data. The inter-comparison and quality assessment of these different techniques have allowed us to obtain a complete and consistent long-term global solar radiation series (1977–2015) at Izaña.

Published: March 2017

Abstract. Application of weather radar data in urban hydrological applications has evolved significantly during the past decade as an alternative to traditional rainfall observations with rain gauges. Advances in radar hardware, data processing, numerical models, and emerging fields within urban hydrology necessitate an updated review of the state of the art in such radar rainfall data and applications. Three key areas with significant advances over the past decade have been identified: (1) temporal and spatial resolution of rainfall data required for different types of hydrological applications, (2) rainfall estimation, radar data adjustment and data quality, and (3) nowcasting of radar rainfall and real-time applications. Based on these three fields of research, the paper provides recommendations based on an updated overview of shortcomings, gains, and novel developments in relation to urban hydrological applications. The paper also reviews how the focus in urban hydrology research has shifted over the last decade to fields such as climate change impacts, resilience of urban areas to hydrological extremes, and online prediction/warning systems. It is discussed how radar rainfall data can add value to the aforementioned emerging fields in current and future applications, but also to the analysis of integrated water systems.
Pionieren met wijkcoaches in Enschede: KISS kon ons nog meer vertellen
Authors: Reussing Rik 
Published: March 2017

Pioneering with social general practitioners in Enschede. KISS could tell us even more
From 2001 (until February 2017), the Dutch province of Overijssel had its own knowledge center, in the area of urban society alongside the national knowledge centers, that was called KISS. In a first essay, an overview of KISS meetings dedicated to citizen participation was given with examples from all over the world. A second essay zoomed in on the Dutch municipality Deventer, a frontrunner in the area of innovative community and area development. This essay focuses on Enschede, a municipality with nearly 160,000 inhabitants in the east of the Netherlands near the German border, as pioneer with the method of the social general practitioners (‘wijkcoaches’) in the Netherlands. Two KISS meetings were devoted to this innovative instrument: the first on its design and on the preliminary results of the project, the second on the final results and on the future of the project. An important role in pioneering was played by the political executives in the municipality and the community of Enschede that showed New Civic Leadership (a concept from Robin Hambleton) by their commitment to the common good and the values of the welfare state. This type of leadership is especially important in a turbulent policy environment like that of social work with decentralizations, financial cuts and shifting policy goals.
Behaviour and welfare: the visitor effect in captive felids
Authors: Suárez P , Recuerda P , Arias-de-Reyna L 
Published: March 2017

AbstractThe influence of visitors on the welfare of captive animals, known as the visitor effect, may in some instances be stressful, adversely affecting animal health. Although the survival of many felid species depends on captive breeding programmes, little is known about this effect. A better understanding of the visitor effect is required to ensure the well-being of felids and the success of breeding programmes. We sought to determine whether the presence of visitors affects behaviour patterns and space use in five feline species in two Spanish zoos: Eurasian lynx (Lynx lynx), jaguar (Panthera onca), bobcat (Lynx rufus),ocelot (Leopardus pardalis) and Asiatic lion (Panthera leo persica) and, if so, whether the effect on animal welfare is positive or negative. To our knowledge, no previous research has addressed the visitor effect in these species, with the exception of the jaguar. Data on animal behaviour, enclosure use, and visitor density were collected during the spring and summer of 2011 and 2012. Changes were observed for all studied species when the zoo was open to the public: four species devoted less time to complex behaviour (ie play, walk) and spent more time resting; ocelots and bobcats made more use of hidden spaces and less use of areas closer to visitors, while the jaguar tended to do the opposite. No correlation was found between visitor density and animal activity, indicating that animals are affected by the mere presence of visitors, regardless of their number. Our findings are in line with those reported by other authors, who have suggested that these behavioural changes are linked to chronic stress. Visitor effect was classed as negative for the welfare of all studied species apart from the jaguar. We advocate the need for future research into potential solutions to mitigate the adverse effect of visitors on felids.
