Photoionization modeling of active galactic nuclei (AGN) predicts that diffuse continuum (DC) emission from the broad-line region makes a substantial contribution to the total continuum emission from ultraviolet through near-infrared wavelengths. Evidence for this DC component is present in the strong Balmer jump feature in AGN spectra, and possibly from reverberation measurements that find longer lags than expected from disk emission alone. However, the Balmer jump region contains numerous blended emission features, making it difficult to isolate the DC emission strength. In contrast, the Paschen jump region near 8200 Å is relatively uncontaminated by other strong emission features. Here, we examine whether the Paschen jump can aid in constraining the DC contribution, using Hubble Space Telescope Space Telescope Imaging Spectrograph spectra of six nearby Seyfert 1 nuclei. The spectra appear smooth across the Paschen edge, and we find no evidence of a Paschen spectral break or jump in total flux. We fit multicomponent spectral models over the range 6800–9700 Å and find that the spectra can still be compatible with a significant DC contribution if the DC Paschen jump is offset by an opposite spectral break resulting from blended high-order Paschen emission lines. The fits imply DC contributions ranging from ∼10% to 50% at 8000 Å, but the fitting results are highly dependent on assumptions made about other model components. These degeneracies can potentially be alleviated by carrying out fits over a broader wavelength range, provided that models can accurately represent the disk continuum shape, Fe ii emission, high-order Balmer line emission, and other components.
Spectroastrometry and Reverberation Mapping: The Mass and Geometric Distance of the Supermassive Black Hole in the Quasar 3C 273

Published: March 2022

The quasar 3C 273 has been observed with infrared spectroastrometry (SA) of the broad Paα line and optical reverberation mapping (RM) of the broad Hβ line. SA delivers information about the angular size and structure of the Paα broad-line region (BLR), while RM delivers information about the physical size and structure of the Hβ BLR. Based on the fact that the two BLRs share the mass of the supermassive black hole (SMBH) and viewing inclination, a combination of SA and velocity-resolved RM (SARM) thereby allows us to simultaneously determine the SMBH mass and geometric distance through dynamically modeling the two BLRs. We construct a suite of dynamical models with different geometric configurations and apply a Bayesian approach to obtain the parameter inferences. Overall the obtained masses and distances are insensitive to specific BLR configurations but more or less depend on parameterizations of the vertical distributions. The most probable model, chosen in light of the Bayes factor, yields an angular-size distance

Published: March 2022

We present a comprehensive analysis of 653 optical candidate counterparts reported during the third gravitational-wave (GW) observing run. Our sample concentrates on candidates from the 15 events (published in GWTC-2, GWTC-3, or not retracted on GraceDB) that had a >1% chance of including a neutron star in order to assess their viability as true kilonovae. In particular, we leverage tools available in real time, including pre-merger detections and cross-matching with catalogs (i.e., point-source, variable-star, quasar and host-galaxy redshift data sets), to eliminate 65% of candidates in our sample. We further employ spectroscopic classifications, late-time detections, and light-curve behavior analyses and conclude that 66 candidates remain viable kilonovae. These candidates lack sufficient information to determine their classifications, and the majority would require luminosities greater than that of AT 2017gfo. Pre-merger detections in public photometric survey data and comparison of cataloged host-galaxy redshifts with the GW event distances are critical to incorporate into vetting procedures, as these tools eliminated >20% and >30% of candidates, respectively. We expect that such tools that leverage archival information will significantly reduce the strain on spectroscopic and photometric follow-up resources in future observing runs. Finally, we discuss the critical role prompt updates from GW astronomers to the EM community play in reducing the number of candidates requiring vetting.

Published: March 2022

We present the results of a time-coincident event search for low-energy electron antineutrinos in the KamLAND detector with gamma-ray bursts (GRBs) from the Gamma-ray Coordinates Network and Fermi Gamma-ray Burst Monitor. Using a variable coincidence time window of ±500 s plus the duration of each GRB, no statistically significant excess above the background is observed. We place the world’s most stringent 90% confidence level upper limit on the electron antineutrino fluence below 17.5 MeV. Assuming a Fermi–Dirac neutrino energy spectrum from the GRB source, we use the available redshift data to constrain the electron antineutrino luminosity and effective temperature.

UV ≳ −22 mag, consistent with galaxy fractions based on 1037 spectroscopically identified sources. Galaxy luminosity functions estimated from the spectroscopic galaxy fractions show the bright-end excess beyond the Schechter function at ≳2σ levels, possibly made by inefficient mass quenching, low dust obscuration, and/or hidden AGN activity. By analyzing the correlation functions at z ∼ 2–6 with HOD models, we find a weak redshift evolution (within 0.3 dex) of the ratio of the star formation rate (SFR) to the dark matter accretion rate,

, indicating the almost constant star formation efficiency at z ∼ 2–6, as suggested by our earlier work at z ∼ 4–7. Meanwhile, the ratio gradually increases with decreasing redshift at z < 5 within 0.3 dex, which quantitatively reproduces the cosmic SFR density evolution, suggesting that the redshift evolution is primarily driven by the increase of the halo number density due to the structure formation, and the decrease of the accretion rate due to the cosmic expansion. Extrapolating this calculation to higher redshifts assuming the constant efficiency suggests a rapid decrease of the SFR density at z > 10 with ∝ 10−0.5(1+z), which will be directly tested with the James Webb Space Telescope.
Periodic Oscillations in LASCO Coronal Mass Ejection Speeds: Space Seismology
Authors: Michalek Grzegorz , Gopalswamy Nat , Yashiro Seiji
Published: March 2022

Coronal mass ejections (CMEs) are energetic eruptions of organized magnetic structures from the Sun. Therefore, the reconnection of the magnetic field during ejection can excite periodic speed oscillations of CMEs. A previous study showed that speed oscillations are frequently associated with CME propagation. The Solar and Heliospheric Observatory mission’s white-light coronagraphs have observed about 30,000 CMEs from 1996 January to the end of 2019 December. This period of time covers two solar cycles (23 and 24). In the present study, the basic attributes of speed oscillations during this period of time were analyzed. We showed that the oscillation parameters (period and amplitude) significantly depend not only on the phase of a given solar cycle but also on the intensity of individual cycles as well. This reveals that the basic attributes of speed oscillation are closely related to the physical conditions prevailing inside the CMEs as well as in the interplanetary medium in which they propagate. Using this approximation, we estimated that, on average, the CME internal magnetic field varies from 18 up to 25 mG between minimum and maximum solar activity. The obtained results show that a detailed analysis of speed oscillations can be a very efficient tool for studying not only the physical properties of the ejections themselves but also the condition of the interplanetary medium in which they expand. This creates completely new perspectives for studying the physical parameters of CMEs shortly after their eruption in the Sun’s environment (space seismology).
Core Electron Heating by Triggered Ion Acoustic Waves in the Solar Wind

Published: March 2022

Perihelion passes on Parker Solar Probe orbits 6–9 have been studied to show that solar wind core electrons emerged from 15 solar radii with a temperature of 55 ± 5 eV, independent of the solar wind speed, which varied from 300 to 800 km s−1. After leaving 15 solar radii and in the absence of triggered ion acoustic waves at greater distances, the core electron temperature varied with radial distance, R, in solar radii, as 1900R
−4/3 eV because of cooling produced by the adiabatic expansion. The coefficient, 1900, reproduces the minimum core electron perpendicular temperature observed during the 25 days of observation. In the presence of triggered ion acoustic waves, the core electrons were isotropically heated as much as a factor of two above the minimum temperature, 1900R
−4/3 eV. Triggered ion acoustic waves were the only waves observed in coincidence with the core electron heating. They are the dominant wave mode at frequencies greater than 100 Hz at solar distances between 15 and 30 solar radii.

Published: March 2022

Gravitational waves from binary neutron star mergers can be used as alerts to enable prompt follow-up observations. In particular, capturing prompt electromagnetic and astroparticle emissions from the moment of a binary merger presents unique constraints on the timescale and sky localization for online gravitational-wave detection. Here we present the expected performance of the SPIIR online detection pipeline that is designed for this purpose in the upcoming international LIGO–Virgo’s 4th Science Run (O4). Using simulated Gaussian data for the two LIGO observatories with expected O4 sensitivity, we demonstrate that there is a nonnegligible opportunity to deliver premerger warnings at least 10 s before the final plunge. These alerts are expected to be issued at a nominal rate of one binary neutron star coalescence per year and localized within a median searched area of 300 deg2. We envision such detection to be extremely useful for follow-up observatories with a large field of view such as the Murchison Widefield Array radio facility in Western Australia.

Published: March 2022

In France, a ‘natural zone of ecological, faunistic or floristic value’ (Zone Naturelle d'Intérêt Écologique, Faunistique et Floristique - ZNIEFF) is a natural area, regionally known for its remarkable ecological characteristics. The ZNIEFF inventory is a naturalist and scientific survey programme launched in 1982 by the Ecology Ministry, with support from the French National Museum of Natural History (MNHN).

This paper describes the ZNIEFF national dataset, which comprises 1,013,725 data for various animal (38%), plant (59%) and fungal (2%) species in terrestrial and marine zones (May 2020). A total of 19,842 sites throughout continental France. as well as in the overseas Departments and territories (Guadeloupe, Martinique, Mayotte, La Réunion, French Guiana, Saint-Martin, Saint-Barthélemy and Saint-Pierre-et-Miquelon), are included in the ZNIEFF dataset (May 2020). This dataset is now available in open access.

All data were collected by skilled naturalists using professional protocols over almost 40 years. They consist mainly of observations of rare, threatened or endemic species, all validated by regional experts. Data are updated twice a year after national validation in both national (INPN-OpenObs) and global (GBIF) biodiversity web platforms. Some of the observed species, the so-called ‘trigger species’ or ‘determinant’ species, are of central interest for a site to be designated a ZNIEFF (zone of high ecological value). This concerns more than 35,000 taxa, mainly angiosperms, insects, fungi, birds and fish.
The lifecycle and ecology of the Spinose Skipper – Favria cribrellum (Eversmann, 1841) in the Republic of North Macedonia (Lepidoptera, Hesperiidae)
Authors: Franeta Filip , Gascoigne-Pees Martin
Published: March 2022

The Spinose Skipper, Favria cribrellum (Eversmann, 1841) [formerly in Muschampia] is considered to be a very localised species in Eastern Europe occurring in only a small number of isolated colonies. Its ecology, especially relating to its host plant, has long remained unknown. Only in the last decade of research has more light been shed on the distribution and habitat requirements of this species in its western range. The host plant of the Spinose Skipper in the Republic of North Macedonia is revealed for the first time. Three eggs and three larvae were discovered in 2017 on a species of Potentilla, tentatively identified as P. detommasii, from a site near Govrlevo, SW of Skopje. The choice of a cinquefoil as a hostplant provides new evidence to support the species recent separation from the genus Muschampia.
Plant diversity and structure in desert communities of the Andean piedmont in Ica, Peru
Authors: Montenegro-Hoyos Angie , Vega Nanette , Linares-Palomino Reynaldo
Published: March 2022

Aims: There is extensive documentation of the floristic composition and plant diversity patterns in the South American coastal deserts and the adjoining arid Puna. Surprisingly, the vegetation along the transition zone from these deserts in the coastal lowlands to the Puna highlands has been little studied. The main goal of this study was to characterize and compare the structure of plant communities in two localities in the Ica department, with the aim of contributing to the floristic knowledge of the desertic western Andean slopes along the lowlands to Andean transition zone.Study area: Huancacasa and La Bolivar localities located at approximately 740 and 3,000 m a.s.l. in the Ica department, Peru.Methods: We sampled 10 plots of 100 m × 60 m located between 740–1,600 m a.s.l. in La Bolivar and 15 modified Whittaker plots (MWPs) of 20 m × 5 m located between 2,800–3,000 m a.s.l. in Huancacasa and recorded species richness and abundance. We estimated alpha diversity, performed Non-Metric Multidimensional Scaling (NMDS) and one-way Similarity (ANOSIM) analyses and plotted rank-abundance curves.Results: We recorded 215 species and morphospecies with coastal and Andean distribution, including 43 species (21.3%) that are either considered endemic to Peru or have been considered under some form of threat by Peruvian or international standards. Both plant communities differed in terms of composition, species richness, abundance, and dominant growth form, with higher values in the communities located at higher elevations. We added 83 species as new records for the Ica department.Conclusions: Our research reinforced the need to increase exploration and documentation of the vegetation within the lowland to highland transition zone along the dry western slopes of the Andes. Our results from such a transition in Ica department in southern Peru, show that much of its plant diversity seems to be, as yet, largely unknown.

Chilean vegetation in the context of the Braun-Blanquet approach and a comparison with EcoVeg formations
Authors: Alvarez Miguel , Luebert Federico
Published: March 2022

Aims: The Braun-Blanquet approach has been widely implemented to generate classification schemes at the country level and Chile is not an exception. In spite of numerous studies, a revised system for the whole country is still missing and most of the current surveys are restricted to a small set of vegetation groups or specific study sites. To fill this gap, we established a vegetation-plot database and updated the classification into a single syntaxonomic scheme. We also performed a comparison of this scheme with the formation system following the EcoVeg approach. Study area: Continental Chile. Methods: We compiled a database of 1,582 plot observations, which are classified into 29 classes, 43 orders, 65 alliances, and 162 associations according to the Braun-Blanquet approach. Results: These observations were assigned to 7 formation classes, 10 subclasses and 19 formations in the EcoVeg approach. There are several mismatches between phytosociological classes and EcoVeg formations, which indicates some inconsistencies in the current stage of syntaxonomy in Chile. Besides a big contrast on bioclimatic conditions within the country’s territory, the occurrence of intrazonal vegetation may explain the high diversity of phytosociological associations recorded in this database. Conclusions: This work may constitute the basis for the implementation of the EcoVeg classification at the levels of alliance and association and can be extended for other countries in the South American sub-continent.

Bifurcation écologique et économie désirable
Authors: Veltz Pierre
Published: March 2022

La série consacrée à la transition écologique et énergétique, ouverte en 2020 dans nos colonnes 1 , revient dans ce numéro de printemps, avec notamment cet article de Pierre Veltz qui souligne l’ampleur des évolutions à engager en la matière. Plus qu’une transition, il s’agit selon lui d’opérer une « bifurcation » et cette bifurcation pose un défi bien plus sociétal que technique. Comme Pierre Veltz le rappelle, les solutions techniques pour répondre au défi écologique, pour l’essentiel, existent ; d’importants gains d’efficacité énergétique sont encore possibles, mais compte tenu de certains freins (tels que l’effet rebond, la non-durabilité de nombreux biens, l’emballement technologique…), la clef la plus efficace consiste à modifier radicalement nos modes de vie. Cette bifurcation ne peut se faire qu’en prenant la voie de la sobriété : une sobriété non seulement individuelle, mais aussi et surtout collective, systémique, orchestrée par la puissance publique, de sorte que les choix menant la France vers l’objectif du zéro émission nette soient cohérents, et que les citoyens comme les acteurs socio-économiques voient, et comprennent, le chemin suivi. Ce cheminement vers ce que Pierre Veltz appelle l’« économie désirable » passe donc par une sobriété structurelle reposant sur une économie « humano-centrée », qui certes existe déjà et continue à se développer à l’échelle micro, localement ; mais doit désormais s’envisager à l’échelle supérieure, via une coordination et une orchestration planifiée par la « machine publique ».

La transition énergétique à l’heure des choix
Authors: Papon Pierre
Published: March 2022

Au cours de l’année 2020, nous avons ouvert, dans Futuribles , une série spécifiquement consacrée à la transition écologique et énergétique 1 . Ces derniers mois, plusieurs organisations ont rendu publics différents travaux visant à alimenter le débat relatif à l’atteinte de la neutralité carbone à l’horizon 2050, objectif affiché par la France (et l’Union européenne) pour lutter contre le changement climatique. Pierre Papon a examiné et comparé les principales publications proposant des scénarios ou des plans d’action en matière de transition énergétique pour la France à l’horizon 2050 (émanant de l’ADEME, RTE, NégaWatt et du Shift Project) ; il détaille ici les enseignements qui en ressortent, venant ainsi compléter notre série lancée en 2020. Dans tous les cas, la feuille de route est sans ambiguïté : il faut inciter à de nouveaux modes de vie pour réduire substantiellement les consommations énergétiques des Français. Ceci implique notamment de modifier les comportements alimentaires, de rénover et transformer les logements, et d’inciter à de nouveaux modes de transport. Pour ce faire, les choix énergétiques diffèrent selon les scénarios mais, comme le montre ici Pierre Papon, la part de l’électricité va croissant, sa production reposant sur une part elle-même en forte hausse des énergies renouvelables, la question du recours au nucléaire étant plus discutée dans les analyses ; plusieurs chiffrages sont avancés. L’accent est mis également sur la décarbonation de l’industrie et de l’agriculture, et l’impact possible des transformations à venir sur l’emploi fait l’objet de plusieurs estimations. Néanmoins, comme le rappelle Pierre Papon, la transition énergétique et les scénarios proposés pour l’accompagner reposent encore sur de nombreuses inconnues, en particulier sur le plan technique. Et du point de vue social, compte tenu des horizons temporels, des inerties propres aux secteurs concernés (logement, transport…) et à nos modes de vie, et des coûts et investissements nécessaires, il est urgent d’organiser une large concertation avec les citoyens, et une planification détaillée des politiques destinées à accomplir effectivement cette indispensable transition.  S.D.

Roland Barthes : La chambre claire
Authors: Berton Jacques
Published: March 2022

Intégrer dans le dispositif formatif le langage photographique et plus particulièrement l’apport de Roland Barthes comme espace potentiel de métissage est resté longtemps une préoccupation intellectuelle, à la fois ludique et créative. Comment sa pensée vient s’immiscer dans le monde des travailleurs sociaux ? C’est à partir des notions de punctum , de signifiance que le texte rappelle combien l’acte photographique rejoint, éclaire la rencontre, la relation éducative ou formative, la clinique de la relation éducative ou formative. Un peu dans la ligne de Jacques Ladsous, la photographie permet, ici, de métaphoriser le travail social et «  La chambre claire  » de Roland Barthes sert de moteur à cette métaphorisation.

Cette inclination est pertinente, déjà reconnue et présente dans les bibliographies des écrits étudiants. Le reconnaître permet de s’interroger sur les raisons et l’usage qui en est fait.
Le retour en milieu familial à la suite d’un placement en protection de l’enfance : regard sur les dynamiques relationnelles entre parents et intervenants sociaux
Authors: Chateauneuf Doris , Drapeau Sylvie , Leblanc Katherine , Saint-Jacques Marie-Christine , Noël Julie , Fortin Marie-Christine
Published: March 2022

La réunification familiale, ou retour en milieu familial, occupe une place importante dans les systèmes de protection de l’enfance. Elle constitue le projet de permanence privilégié pour un nombre important d’enfants placés en milieu substitut, mais pose tout de même des défis notables aux intervenants et parents appelés à travailler conjointement pour le retour de l’enfant dans sa famille. Les enjeux relationnels que sous-tend la réunification familiale peuvent s’avérer déterminants sur le devenir et la trajectoire des familles. La présente étude se penche sur les relations entre intervenants et parents en contexte de réunification familiale. Elle s’appuie sur l’analyse de 72 entretiens individuels menés auprès de parents et d’intervenants impliqués dans 36 cas de réunifications familiales. Les résultats font état de quatre profils relationnels et identifient les principales caractéristiques associées à chacun d’entre eux.
Entre précoce et prématuré, l’originaire. Quelques propositions
Authors: Scarfone Dominique
Published: March 2022

L’auteur explore, en quarante-cinq brèves propositions, la proximité et la différence entre « précoce » et « prématuré », en y insérant la question de l’originaire et de l’après-coup. Il est proposé, entre autres, que le précoce relève de l’observation empirique en termes de développement tandis que le prématuré renvoie d’abord au constat de la situation particulière du nouveau-né à la prématurité statutaire. Situation dans laquelle il importe de tenir compte de l’observateur qui en fait le constat, de sorte que l’Hilflösigkeit chez l’humain concerne une relation et donc le nouveau-né, mais aussi l’adulte qui en a soin. Entre les notions de précoce et de prématuré s’insère la notion winnicottienne de profond, qui invoque une complexité psychique redevable de l’après-coup, même si Winnicott ne s’y réfère pas nommément. Objet d’analyse, le profond renvoie à l’originaire comme temps actuel, c’est-à-dire ni précoce ni prématuré, sorte de source temporelle dont le précoce et le prématuré se présentent comme des cristallisations.
Adolescents précoces : clivage et numérique pour abriter l’espace transitionnel
Authors: Chocron Michael
Published: March 2022

L’adolescence des sujets précoces intellectuellement donne à voir une utilisation spécifique du numérique qui a pour but de créer une distance dans la relation avec les figures parentales. Cette utilisation de l’objet numérique, donnant souvent l’impression aux parents d’être démunis, a valeur de limite. Elle peut se lire comme une réaffirmation d’un processus plus ancien, en lien avec l’activation précoce du moi, amenant à restriction de l’accès des parents à l’espace transitionnel. Celle-ci intervient dans le cadre de relation avec les parents que l’enfant peut vivre comme envahissante. Au travers d’un cas clinique d’adolescent reconnu précoce (avec une échelle d’intelligence), nous verrons comment cette limite, qui implique une mise à distance des objets également présente dans le transfert, a des effets sur l’intelligibilité du fonctionnement psychique de l’adolescent. Cela amène à interroger comment le mécanisme d’intellectualisation s’empare du numérique et plus particulièrement le jeu vidéo comme lieu de réaffirmation de cette limite.
L’hypermaturité intellectuelle à l’épreuve du pubertaire et du processus thérapeutique
Authors: Blanchet Claire , Henric-Gras Geneviève , Konicheckis Alberto
Published: March 2022

L’hypermaturité intellectuelle, en tant qu’elle prend ses racines dans le sexuel, est interrogée dans sa constitution, ses fonctions et ses conséquences. Elle est envisagée après Ferenczi comme la face visible d’un auto-clivage narcissique précoce qui se forme en réaction à la séduction du sexuel de l’adulte et ayant pour conséquence d’entraver le développement de la sexualité infantile. Partant du travail clinique avec un adolescent, les auteurs montrent comment, une fois créées les conditions favorables à l’émergence du transfert négatif, à la mise en jeu du processus pubertaire et à l’intensification du transfert, se produit le démontage progressif de l’hypermaturité intellectuelle laissant apparaître, avec violence, la partie enfouie du clivage. La présence d’un environnement thérapeutique présent et non empiétant permet la constitution d’assises narcissiques nouvelles, sur lesquelles le patient peut se confronter au sexuel et à l’élaboration de l’Œdipe sans recourir à la défense par l’hypermaturité.
Le courant contre-transférentiel et son implication dans la séance
Authors: Pacquement Brigitte
Published: March 2022

C’est grâce au travail corporel sur la perception et les sensations que la patiente a pu faire des liens avec son histoire et retrouver des traces mnémoniques figées, gelées, enkystées dans sa vie psychique. La sensorialité souvent vue comme anti-pensée favorise ici dans le travail de PPC l’appropriation subjective et permet la reprise du mouvement de vie. Comment une patiente a pu bénéficier du contre-transfert de son analyste pour retrouver un sentiment d’existence.
Naissance de l’économie politique, idéologie propriétariste et Révolution française
Authors: Orain Arnaud
Published: March 2022

Cet article discute et prolonge les éléments d’histoire intellectuelle avancés par Thomas Piketty dans la première partie de Capital et idéologie , autour du passage d’une société trifonctionnelle (noblesse, clergé, tiers état) à une société propriétariste dans la France du xviii e siècle. Il s’intéresse en particulier à la dichotomie entre deux conceptions de l’économie politique à sa naissance (transcendance contre contingence), qui renvoie au partage entre partisans et adversaires de la naturalisation de la propriété, du marché, des inégalités et de la science. L’article tente également d’expliquer la victoire de la logique propriétariste, qui est en même temps celle de la physiocratie, sous la Révolution française.
Les industries culturelles françaises et le pouvoir d’influence
Authors: Chaubet François
Published: March 2022

La diplomatie culturelle française, historiquement constituée autour d’une politique de diffusion de la langue à la fin du XIX e  siècle, a été longtemps réticente à l’utilisation des industries culturelles, à l’exception toutefois des filières du livre et du cinéma. Celles-ci ont en effet bénéficié d’aides diverses pour leur exportation ou pour leur protection globale. Les années 1980 ont marqué un changement d’attitude. La recherche d’une influence culturelle plus tangible, en partie d’ordre économique, s’est affirmée avec la création des attachés audiovisuels, notamment au sein des ambassades. Autour du tourisme sportif ou d’une active politique d’expansion muséale à l’étranger, la diplomatie culturelle française tente désormais de combiner plus harmonieusement culture et économie.
Les ICC françaises à la conquête de l’international
Authors: Lecourtier Christophe
Published: March 2022

Les industries culturelles et créatives (ICC) françaises sont en pleine expansion, en France et dans le monde. En ce qu’elles sont et parce qu’elles contribuent au rayonnement international de notre pays, elles constituent en outre un facteur déterminant d’attractivité et de stimulation générale de nos exportations. Le potentiel export de ces entreprises pâtit cependant de leur taille réduite, de leur faible propension à croître et de leur investissement encore insuffisant dans le numérique. Néanmoins, le dynamisme entrepreneurial de la filière, les mesures prises par le gouvernement et l’extension de l’accompagnement à l’export par immersion laissent augurer un essor renouvelé de nos ICC après la parenthèse de la crise sanitaire.
Pour un égal accès au livre
Authors: Duval Frédéric
Published: March 2022

Le commerce en ligne et l’innovation technologique sont des opportunités pour l’industrie du livre, et pour la lecture en général. Opposer les canaux de diffusion des biens culturels en surtaxant les ventes en ligne creuserait les inégalités territoriales au nom d’une vaine querelle des Anciens et des Modernes. Les lecteurs et la lecture en seraient les grands perdants.
Adolescents en institution, autonomie en question
Authors: Nyssens Grégoire , Tigra Oussama
Published: March 2022

Pour les adolescents placés en institution, l’approche de la majorité à 18 ans devient parfois un mirage rêvé ou un fantasme cauchemardesque qui provoque un départ prématuré en forme de rupture. Si la séparation s’impose à l’arrivée de la majorité, pour qu’elle ne devienne pas rupture, elle doit déjà s’inscrire au départ, dès la prise de contact. En effet, grandir en autonomie n’implique pas de devenir un être indépendant solitaire mais plutôt de trouver sa place dans la danse relationnelle de l’interdépendance faite d’aller et retour. La thérapie institutionnelle qui nécessite une approche interdisciplinaire tente cette danse relationnelle dans le monde du sentir propre à l’ambiance du milieu humain (E. Dessoy) et à la modalité du contact (J. Schotte). Un atelier Snoezelen vient concrétiser cet effort de modélisation.
Developing a Statewide Research Compendium: Key Points and Steps for Success
Authors: Embree Jennifer L. , Lyons Deborah J. , Adams Cynthia , Heinzman Susanne , Oetting Stephanie , Swenty Connie
Published: March 2022

Engaging clinical nurses in nursing research requires value for the nurses and a structured process. One way to involve nurses in research is through development of a research compendium. A professional development specialist can lead the creation of a research compendium. Identifying key stakeholders, developing a technologic infrastructure, piloting the compendium, gaining feedback, and identifying outcomes that will be evaluated are key.

Nursing Student Medication Administration Practice in the Clinical Setting: A Descriptive Study
Authors: Jarvill Melissa , Neubrander Judy , Kim MyoungJin
Published: March 2022

Background:

Nurses are instrumental in preventing medication errors that cause patient harm. Increased practice and educational interventions are suggested to prepare nursing students to safely administer medications. However, a quantified account of the reality of nursing student medication administration practice in the clinical setting is unknown.

Method:

This cross-sectional descriptive study assessed the frequency and quality of nursing student medication administration practice in the clinical setting. A convenience sample of prelicensure nursing students (n= 222) completed an electronic Nursing Student Medication Administration Survey after each clinical day for one semester.

Results:

Overall, participants on average had one medication administration experience, administered two drugs, and administered medications to one patient. Most medication administration experiences were supervised by bedside RNs.

Conclusion:

Medication administration opportunities in the clinical setting are unpredictable and vary by facility and nursing program policy. Further investigation is necessary.[J Nurs Educ. 2022;61(3):137–142.]
Sexual and Reproductive Health Content in the 3 Ps in Nurse Practitioner Education
Authors: Cappiello Joyce D. , Boardman Maureen B.
Published: March 2022

Background:

Nurse practitioners (NPs) in primary care provide sexual and reproductive health care, an integral component of health and well-being. This study explored the degree of inclusion of sexual and reproductive health content in the foundational courses in NP preparation including advanced health assessment, advanced physiology and pathophysiology, and advanced pharmacology, known as the 3 Ps.

Method:

Qualitative interviews were conducted with 30 NPs in their first 2 years of practice.

Results:

Sexual and reproductive health content was well integrated into advanced assessment courses, although participants wanted more comfort and skill with discussing sensitive sexual health issues. Advanced pharmacology and advanced pathophysiology courses were not likely to include the content.

Conclusion:

Interactive learning opportunities, such as simulation with feedback, promote communication skills with sensitive health issues. Foundational courses would benefit from a deeper understanding of the menstrual cycle, sexual functioning, and medications specific to sexual and reproductive health.

We investigated the leptospirosis epidemic model by using Caputo and Fabrizio fractional derivatives. Picard's successive iterative method and Sumudu transform are taken into consideration for developing the iterative solutions for the leptospirosis disease. Employing nonlinear functional analysis, the stability and uniqueness of the proposed model are established. Sensitivity analysis is taken into account to highlight the most sensitive parameters corresponding to the basic reproductive number. Various solutions to the proposed system have been interpolated by graphs with the application of Matlab software.

Muscle coordination and motor function of stroke patients are weakened by stroke-related motor impairments. Our earlier studies have determined alterations in inter-muscular coordination patterns (muscle synergies). However, the functional connectivity of these synergistically paired or unpaired muscles is still unclear in stroke patients. The goal of this study is to quantify the alterations of inter-muscular coherence (IMC) among upper extremity muscles that have been shown to be synergistically or non-synergistically activated in stroke survivors. In a three-dimensional isometric force matching task, surface EMG signals are collected from 6 age-matched, neurologically intact healthy subjects and 10 stroke patients, while the target force space is divided into 8 subspaces. According to the results of muscle synergy identification with non-negative matrix factorization algorithm, muscle pairs are classified as synergistic and non-synergistic. In both control and stroke groups, IMC is then calculated for all available muscle pairs. The results show that synergistic muscle pairs have higher coherence in both groups. Furthermore, anterior and middle deltoids, identified as synergistic muscles in both groups, exhibited significantly weaker IMC at alpha band in stroke patients. The anterior and posterior deltoids, identified as synergistic muscles only in stroke patients, revealed significantly higher IMC in stroke group at low gamma band. On the contrary, anterior deltoid and pectoralis major, identified as synergistic muscles in control group only, revealed significantly higher IMC in control group in alpha band. The results of muscle synergy and IMC analyses provide congruent and complementary information for investigating the mechanism that underlies post-stroke motor recovery.
Epileptic seizures and link to memory processes
Authors: Das Ritwik ,   Department of Neuroscience, Canadian Centre for Behavioural Neuroscience, University of Lethbridge, Lethbridge, AB, Canada, Luczak Artur
Published: March 2022

Epileptogenesis is a complex and not well understood phenomenon. Here, we explore the hypothesis that epileptogenesis could be “hijacking” normal memory processes, and how this hypothesis may provide new directions for epilepsy treatment. First, we review similarities between the hypersynchronous circuits observed in epilepsy and memory consolidation processes involved in strengthening neuronal connections. Next, we describe the kindling model of seizures and its relation to long-term potentiation model of synaptic plasticity. We also examine how the strengthening of epileptic circuits is facilitated during the physiological slow wave sleep, similarly as episodic memories. Furthermore, we present studies showing that specific memories can directly trigger reflex seizures. The neuronal hypersynchrony in early stages of Alzheimer's disease, and the use of anti-epileptic drugs to improve the cognitive symptoms in this disease also suggests a connection between memory systems and epilepsy. Given the commonalities between memory processes and epilepsy, we propose that therapies for memory disorders might provide new avenues for treatment of epileptic patients.
