Variaciones del documental cinematográfico agrario sobre el olivo en la España franquista: del marqués de Villa Alcázar al No-Do = Variations of the agrarian documentary film in Francoist Spain: From Marqués de Villa Alcázar to the No-Do
Authors: Poyato Sánchez Pedro 
Published: October 2018

Resumen: En el siglo XX fructificó una producción cinematográfica de documentales agrarios sobre el olivar en la que, junto a hilos protagónicos más o menos comunes –plantación del olivo, recogida de la aceituna, extracción y almacenamiento del aceite….-, coexistían otros –juegos visuales propiciados por los troncos nudosos del olivo, toques religiosos emanados de las aplicaciones del aceite, eventos vinculados a la fiesta del remate…- que, más allá de atender a la dimensión didáctica, introducían componentes políticas o culturales, potenciando así el tejido discursivo del documental. Este trabajo pasa a revista a una serie de esos documentales, entre ellos varios dirigidos por el marqués de Villa Alcázar y una producción del No-Do de 1952, para dar cuenta, a partir de un análisis comparativo de los mismos, de esos hilos anteriores y de su entrecruzamiento con el fin de sacar a la luz las texturas que definen los discursos cinematográficos correspondientes. Abstract: The 20th century saw the rise of film productions of agrarian documentaires upon on the olive grove that, besides common major themes -olive planting and harvest, oil extraction and storage- portrayed other visual elements favored by the knurled trunks of the olive tree, the religious touches derived from the oil applications, or events linked to the festivity that marked the end of the harvest period. Elements, in all, that rather than addressing to the didactic dimension, introduced cultural and political aspects, thus fostering the discursive structure of the documentary itself. The present paper revisits a series of documentaries of that particular genre, some of them directed by the Marqués de Villa Alcázar, and a 1952 No-Do´s production, to deliver, starting from a comparative analysis of these works, of previous examples and their intersection, whith the aim of revealing the textures that define the underlying cinematographic discourses.
Je e(s)t un Autre - Philosophie et Esthétiques du dédoublement
Authors: Heurtebise Jean-Yves 
Published: October 2018

Vouloir étudier les notions de double et de dédoublement, c’est tenter de
repenser la notion d’identité. C’est chercher à saisir la constitution de la
subjectivité et de la personne dans le rapport du Je et de l’autre, c’est chercher à
penser leur rapport : pas simplement de l’autre en tant que autrui mais de l’autre
en tant que autre du Je. Et cela à différents niveaux autant philosophique, que
politique et psychologique. Au point de vue philosophique et plus encore
épistémologique, notre intention serait de redéfinir la notion de « sujet » pour
sortir du point de vue classique en s’aidant notamment des concepts propres au champ
de la physique quantique. Il faudrait penser une figure de la subjectivité
n’impliquant pas nécessairement l’identité à soi.
Bifurcations conjugales, remises en couple et place de l’enfant : donner du temps au temps, pour inventer d’autres configurations familiales
Authors: Négroni Catherine 
Published: October 2018

Cadre de la recherche : De nombreux travaux se sont intéressés à la complexité des familles recomposées ; cependant, on compte moins de recherches qualitatives sur les bifurcations conjugales et les configurations familiales post-rupture visant à éclairer l’incidence des enfants dans la remise en couple des parents.
Objectifs : Le présent article interroge les temporalités recomposées et, plus particulièrement, les temps synchrones et asynchrones des rôles parentaux et conjugaux, comment la famille se défait et se recompose à travers le rôle et la place de l’enfant dans les remises en couples.
Méthodologie : L’enquête qualitative a été réalisée dans une ville moyenne de France, auprès d’hommes et de femmes en situation de post-rupture. Nous avons recueilli trente récits de vie, soit seize récits de femmes, onze récits d’hommes et trois entretiens de personnes en couple homoparental.
Résultats : Nos principaux résultats font état de parcours de remise en couple assez différenciés, en regard du capital économique et social acquis, de la catégorie socio-professionnelle, du genre, mais aussi en fonction de la place et de l’âge des enfants. Les remises en couple sont genrées. Les temps de remise en couple sont plus longs pour les femmes lorsqu’elles ont la garde principale des enfants. L’âge à la séparation est apparu déterminant dans les parcours de remise en couple des femmes.
Conclusions : Ce travail questionne la parentalité en regard de la remise en couple : comment le couple parental continue-t-il d’exister en dépit de la cessation du couple conjugal ?
Contribution : Dans une approche qualitative, cette étude analyse les reconfigurations familiales post-rupture et montre que la parentalité vient entrechoquer la conjugalité dans des configurations familiales constamment renégociées.
Y avait-il un père ? Paternité et relations de couple dans les affaires de néonaticides
Authors: Simmat-Durand Laurence 
Published: October 2018

Cadre de la recherche : Les affaires de néonaticide sont essentiellement connues au travers de la procédure judiciaire qui garde une approche très traditionnelle d’un crime exclusivement féminin et qui ne met en cause que la mère.
Objectifs : Le présent article s’attache à analyser ce qui est décrit de l’attitude du partenaire de la mère vis-à-vis de la paternité, et ce faisant les relations de couple qui y sont attachées.
Méthodologie : À partir de 2306 articles de presse décrivant 357 néonaticides suspectés en France de 1993 à 2012, une analyse thématique a été réalisée, utilisant toutes les mentions au père de l’enfant.
Résultats : Trois grandes tendances ont été mises en exergue : l’homme qui a conçu cet enfant, soit n’est pas envisagé dans ce rôle de père, car il est écarté de la paternité par la mère ou par la justice, soit ne veut pas être père, soit veut être père, mais en est empêché par la mère.
Conclusions : Contrairement à la littérature sur la parentalité aujourd’hui, les affaires de néonaticide mettent en scène une vision stéréotypée où la mère est seule à répondre du désir d’enfant. Ainsi, lors des poursuites judiciaires pour néonaticide, la présence du père est déniée, refusée, que le désir paternel existe ou non.
Contribution : Cet article fait le point sur l’existence donnée au père dans le contexte des poursuites judiciaires des mères à partir d’un corpus de presse concernant 141 mères ayant été poursuivies pour nénonaticide.
Cartographie des zones potentielles de recharge de la nappe de Bonoua (sud-est de la Côte d’Ivoire)
Authors: Ake Gabriel Etienne , Kouame Kan Jean , Koffi Affoué Bénédicte , Jourda Jean Patrice 
Published: October 2018

Ce travail a pour objectif de déterminer les zones favorables à la recharge de la nappe de Bonoua par approche cartographique et système d’information géographique (SIG). La détermination de ces zones potentielles de recharge de la nappe a nécessité le croisement des informations spatiales relatives aux différents paramètres régissant la recharge qui sont exprimés en cartes thématiques. Une reclassification suivie d’une pondération de ces paramètres a été faite selon leur degré d’implication dans le processus de recharge par l’analyse multicritère Analytical Hierarchy Process (AHP) de Saaty. Ils sont par la suite intégrés dans un SIG afin d’établir la carte des zones potentielles de recharge de la nappe. L’analyse de cette carte a révélé cinq classes, dont une classe de bonne recharge couvrant 66 % de la zone étudiée. Celle-ci est localisée en majorité dans la partie centrale de la nappe, précisément dans le Continental Terminal, constitué principalement de sables grossiers avec des pentes relativement faibles où le sol est occupé par des cultures industrielles. Les zones de faible recharge (34 % de la zone étudiée) sont localisées sur les bordures ouest et est de la zone d’étude sur les sols hydromorphes. Cette carte de répartition spatiale de la recharge peut être considérée comme un support d’aide à la décision, notamment pour la gestion de la ressource en eau et l’analyse de la vulnérabilité des eaux souterraines. Les zones de recharge préférentielle méritent une attention particulière des autorités par l’instauration de mesures de protection.
À propos du Chili et de l'évolution du roman. Entretien avec Roberto Gac
Authors: Wallace David 
Published: October 2018

Dans le monde de la littérature, le Chili est reconnu surtout par ses poètes (Gabriela Mistral et Pablo Neruda, tous deux prix Nobel). Ses romanciers, en dehors de Roberto Bolaño, n'ont jamais atteint le même niveau de prestige. Il y a également une lignée d'écrivains d'avant-garde qui va de Vicente Huidobro dans les années 30 (son œuvre, à l'époque réputée en France et en Espagne, est en partie écrite en français), jusqu'à Jean Emar, Juan-Agustín Palazuelos et Mauricio Wacquez, pendant la deuxième moitié du 20e siècle. Dans cet entretien David Wallace, professeur de littérature à l'Université du Chili, donne, à travers ses questions, un aperçu de l'évolution de la narrative chilienne en particulier et de la narrative hispanique en générale, tout en laissant ouverte la question du roman comme genre littéraire face aux nouvelles technologies et à l'invention de l'écriture électronique.

AbstractRecently, inorganic cesium–lead halide perovskites with high thermal stability have attracted much attention as promising light‐emitting material for research of perovskite‐based light‐emitting diodes (PeLEDs) toward high‐definition displays. However, the CsPbI3‐based red PeLEDs still suffer low external quantum efficiency (EQE) and poor device stability due to the spontaneous phase transition from cubic CsPbI3 (α‐CsPbI3) to nonradiative orthorhombic phase (δ‐CsPbI3) under ambient conditions. Here, a feasible approach is reported on phase engineering by incorporating the long‐chain cation (e.g., 2‐(naphthalene‐1‐yl)ethanamine (NEA)) in CsPbI3 for stable and high‐performance CsPbI3‐based red light‐emitting diodes (LEDs). A high EQE of 8.65% is successfully achieved for the characteristic red emission at ≈682 nm representing the highest value among Cs‐based red PeLEDs up to now. More importantly, the corresponding PeLEDs exhibit outstanding stability with EQE retaining 90% after 3 months of storage. These results verify the potential of using cesium‐based inorganic perovskite as viable alternatives to methylammonium (MA)‐ or formamidinium (FA)‐based perovskite for desirable practical applications.

Abstractvan der Waals (vdW) heterojunctions enable arbitrary combinations of different layered semiconductors with unique band structures, offering distinctive band engineering for photonic and optoelectronic devices with new functionalities and superior performance. Here, an interlayer photoresponse of a few‐layer MoSe2/WSe2 vdW heterojunction is reported. With proper electrical gating and bias, the heterojunction exhibits high‐sensitivity photodetection with the operation wavelength extended up to the telecommunication band (i.e. 1550 nm). The photoresponsivity and normalized photocurrent‐to‐dark current ratio reach up to 127 mA W−1 and 1.9 × 104 mW−1, respectively. The results not only provide a promising solution to realize high‐performance vdW telecommunication band photodetectors, but also pave the way for using sub‐bandgap engineering of two‐dimensional layered materials for photonic and optoelectronic applications.

AbstractRecently, research interest in brain‐inspired neuromorphic computing based on robust and intelligent artificial neural networks has surged owing to the ability of such technology to facilitate massive parallel, low‐power, highly adaptive, and event‐driven computing. Here, a photosynaptic device with a novel weight updating mechanism for high‐speed and low‐power optoelectronic spike processing is proposed, wherein a synaptic weight is controlled by a mixed spike consisting of voltage and light spikes; the light spike, in particular, boosts up the probability of electron detrapping from graphene oxide charge‐trapping layer to the photosensitive indium–gallium–zinc oxide charge‐transporting layer. Compared to electrically operating synaptic device, the magnitude of conductance change in the proposed photosynaptic device increases remarkably from 2.32 to 5.95 nS without degradation of the nonlinearity (potentiation/depression values are changed from 4.24/8 to 5/8). Owing to this enhancement of synaptic operation, the recognition rates for the Modified National Institute of Standards and Technology digit patterns improve from 36% and 49% to 50% and 62% in artificial neural networks using long‐term potentiation/depression characteristics with 20 and 100 weight states, respectively. The proposed photosynaptic device technology capable of optoelectronic spike processing is expected to play a crucial role in the implementation of neuromorphic computing in the future.

AbstractAntibody‐based medicines and nanomedicines are very promising for cancer therapy due to the high specificity and efficacy of antibodies. However, antibody‐drug conjugates and antibody‐modified nanomaterials frequently suffer from low drug loading and loss of functions due to the covalent modification of the antibody. A novel and versatile strategy to prepare supramolecular nanomaterials by the coassembly of an affibody (antiHER2) and drug‐peptide amphiphiles is reported here. During the enzyme‐instructed self‐assembly process, the drug‐peptide amphiphile can coassemble with the affibody, resulting in supramolecular nanofibers in hydrogels. The drug loading in the supramolecular nanofibers is high (>30 wt%), and the stability of antiHER2 is significantly improved in the nanofibers at 37 °C (>15 d in vitro). The supramolecular nanofibers exhibit high affinity for HER2+ cancer cells and can be efficiently taken up by these cells. In a mouse tumor model, the supramolecular nanofibers abolish HER2+ NCI‐N87 tumor growth due to the good accumulation and retention of nanofibers in tumor. This study provides a novel strategy to prepare nanomedicines with high drug loading and high specificity.

AbstractTin and its derivatives have provoked tremendous progress of high‐capacity sodium‐ion anode materials. However, achieving high areal and volumetric capability with maintained long‐term stability in a single electrode remains challenging. Here, an elegant and versatile strategy is developed to significantly extend the lifespan and rate capability of tin sulfide nanobelt electrodes while maintaining high areal and volumetric capacities. In this strategy, in situ bundles of robust hierarchical graphene (hG) are grown uniformly on tin sulfide nanobelt networks through a rapid (5 min) carbon‐plasma method with sustainable oil as the carbon source and the partially reduced Sn as the catalyst. The nucleation of graphene, CN (with size N ranging from 1 to 24), on the Sn(111) surface is systematically explored using density functional theory calculations. It is demonstrated that this chemical‐bonded hG strategy is powerful in enhancing overall electrochemical performance.

AbstractSteam sterilization is widely used as one of the most reliable sterilization methods for public health. However, traditional steam sterilization mainly relies on electricity, a constrained resource for many developing countries and areas. The lack of available and affordable sterilization techniques in these areas is exposing human beings to a high risk of various epidemic diseases, and calls for the development of off‐grid sterilization solutions. For the first time, the kinetic advantages of interfacial solar steam generation is fundamentally revealed and it is demonstrated that interfacial solar steam generation can enable fast‐responsive (as short as 8.4 min for a full sterilization cycle) and energy‐efficient (100 J mL−1 for steam reaching 121 °C) sterilization, superior to those of the conventional sterilization techniques. The key solar absorber is made of low cost and widely available biochar. A proof‐of‐concept sterilization system with a 10.5 L solar autoclave is built with very low cost of whole life‐cycle and operates with minimum carbon footprint. Effective sterilization (≈99.999999% inactivation of pathogen), exceeding the requirements of Food and Drug Administration is demonstrated, making the sterilization strategy a promising and complementary personalized sterilization solution, particularly beneficial for off‐grid areas.

AbstractIn recent years, an intense research effort has focused on the flexible manipulation of electromagnetic (EM) waves using metamaterials. As an important category, gradient metamaterials (metamaterials with gradient phases) can impart subwavelength‐scale space‐variant phase changes during the electromagnetic wave propagations to shape EM radiations in which arrays of elements with certain phase gradients can form EM beam propagations as desired. Here, the concept of space‐frequency‐domain gradient metamaterial is proposed, in which new degrees of freedom are attained by introducing frequency‐domain phase gradients to the metamaterial. The frequency gradients of the metamaterial are obtained by the derivative of phase gradients with respect to frequency, which can be used to shape the uniformly distributed phase gradients to vary as demand in the working frequency band without any active devices. The combinations of space and frequency gradients in metamaterials in 1D/2D open new possibilities for more powerful controls of EM waves, thereby yielding more complicated functions such as 2D flexible beam scanning, continuous transformations of vortex modes, and generation of multiple beams with desired transmission directions and transmission modes.

Published: October 2018

AbstractOrganoboron compounds are versatile synthetic building blocks. We herein report a new strategy, a photochemical gold‐catalyzed chemo‐selective Hiyama arylation of B,Si bifunctionalized reagents with diazonium salts, which is orthogonal to common strategies and therefore a unique tool for synthesis of valuable biarylboronates. With this new methodology a wide array of diversely functionalized sp2‐ and sp3‐hybridized biarylboronates were obtained. Notably, the synergism of gold catalysis with copper catalysis or palladium catalysis, allows for one‐pot iterative C−X (heteroatom) and C−C couplings for the rapid assembly of several simple fragments to relatively complex molecules. Mechanistic studies indicated that photosensitizer‐free conditions were superior to gold/Ru(bpy)3Cl2 dual catalysis.

Published: October 2018

AbstractWe present the “on water” surface‐initiated Cu‐mediated controlled radical polymerization (“on water” SI‐CuCRP) that converts hydrophobic monomers in aqueous reaction medium to polymer brushes at unparalleled speed and efficiency. The method allows the facile conversion of a variety of common monomers under most simple reaction conditions and with minimal monomer amounts to thick and homogeneous polymer brushes. The highly living character of the “on water” SI‐CuCRP allowed the preparation of decablock (homo)polymer brushes and opens the pathway to sequentially controlled polymer brushes on solids.

Published: October 2018

AbstractApplication of nanostructured silicon (nSi) is significantly retarded by challenges in the production of affordable nSi. We herein report a high‐yield (ca. 100 %) and low‐energy (2 kWh Kg‐nSi−1) nanostructuring of industrial microsized silicon (mSi) through a closed‐loop electrochemical Mg alloying/dealloying in molten MgCl2/NaCl/KCl at 773 K. The resulting nSi unexpectedly shows a salt‐unwetted character, allowing an automatic separation from the melts. Thus water washing and accompanying oxidation of the nSi can be avoided. The final product has a nanoporous structure and comprises Si nanorods (ca. 30 nm in diameter) with an ultrathin oxide coating. It can be used for Li storage giving a combination of high initial coulombic efficiency, high specific capacity, and long cycling stability. This nanostructuring process consumes very few chemicals except for the mSi and produces almost zero waste.

AbstractBy combining rotational spectroscopy in supersonic expansion with the capability of state‐of‐the‐art quantum‐chemical computations in accurately determining structural and energetic properties, the genuine nature of a sulfur–sulfur chalcogen bond between dimethyl sulfide and sulfur dioxide has been unveiled in a gas‐jet environment free from collision, solvent and matrix perturbations. A SAPT analysis pointed out that electrostatic S⋅⋅⋅S interactions play the dominant role in determining the stability of the complex, largely overcoming dispersion and C−H⋅⋅⋅O hydrogen‐bond contributions. Indeed, in agreement with the analysis of the quadrupole‐coupling constants and of the methyl internal rotation barrier, the NBO and NOCV/CD approaches show a marked charge transfer between the sulfur atoms. Based on the assignment of the rotational spectra for 7 isotopologues, an accurate semi‐experimental equilibrium structure for the heavy‐atom backbone of the molecular complex has been determined, which is characterized by a S⋅⋅⋅S distance (2.947(3) Å) well below the sum of van der Waals radii.
