Magnetization Reversal Modes in Short Nanotubes with Chiral Vortex Domain Walls
Authors: Chen Ai , Gonzalez Julian , Guslienko Konstantin
Published: January 2018

Micromagnetic simulations of magnetization reversal were performed for magnetic nanotubes of a finite length, L, equal to 1 and 2 μm, 50 and 100 nm radii, R, and uniaxial anisotropy with “easy axis” parallel to the tube length. I.e., we considered relatively short nanotubes with the aspect ratio L/R in the range 10–40. The non-uniform curling magnetization states on both ends of the nanotubes can be treated as vortex domain walls (DW). The domain wall length, Lc, depends on the tube geometric parameters and the anisotropy constant Ku, and determines the magnetization reversal mode, as well as the switching field value. For nanotubes with relative small values of Lc (Lc/L < 0.2) the magnetization reversal process is characterized by flipping of the magnetization in the middle uniform state. Whereas, for relative large values of Lc, in the reverse magnetic field, coupling of two vortex domain walls with opposite magnetization rotation directions results in the formation of a specific narrow Néel type DW in the middle of the nanotube. The nanotube magnetization suddenly aligns to the applied field at the switching field, collapsing the central DW.
Unexpected Ground-State Structure and Mechanical Properties of Ir2Zr Intermetallic Compound
Authors: Zhang Meiguang , Cao Rui , Zhao Meijie , Du Juan , Cheng Ke
Published: January 2018

Using an unbiased structure searching method, a new orthorhombic Cmmm structure consisting of ZrIr12 polyhedron building blocks is predicted to be the thermodynamic ground-state of stoichiometric intermetallic Ir2Zr in Ir-Zr systems. The formation enthalpy of the Cmmm structure is considerably lower than that of the previously synthesized Cu2Mg-type phase, by ~107 meV/atom, as demonstrated by the calculation of formation enthalpy. Meanwhile, the phonon dispersion calculations further confirmed the dynamical stability of Cmmm phase under ambient conditions. The mechanical properties, including elastic stability, rigidity, and incompressibility, as well as the elastic anisotropy of Cmmm-Ir2Zr intermetallic, have thus been fully determined. It is found that the predicted Cmmm phase exhibits nearly elastic isotropic and great resistance to shear deformations within the (100) crystal plane. Evidence of atomic bonding related to the structural stability for Ir2Zr were manifested by calculations of the electronic structures.
The Radiofrequency NMR Spectra of Lithium Salts in Water; Reevaluation of Nuclear Magnetic Moments for 6Li and 7Li Nuclei
Authors: Makulski Włodzimierz
Published: January 2018

LiCl and LiNO3 water solutions in the presence of small amounts of 3-helium have been investigated by means of multinuclear resonance spectroscopy. The resulting concentration dependences of the 3He, 6,7Li+, 14NO3− and 35Cl− resonance radiofrequencies are reported in the infinite limit. This data along with new theoretical corrections of shielding lithium ions was analyzed by a known NMR relationship method. Consequently, the nuclear magnetic moments of 6Li and 7Li were established against that of the helium-3 dipole moment: μ(6Li) = +0.8220457(50)μN and μ(7Li) = +3.256418(20)μN. The new results were shown to be very close to the previously obtained values of the (ABMR) atomic beam magnetic resonance method. This experiment proves that our helium method is well suited for establishing dipole moments from NMR measurements performed in water solutions. This technique is especially valuable when gaseous substances of the needed element are not available. All shielding constants of species present in water solutions are consistent with new nuclear magnetic moments and these taken as a reference. Both techniques—NMR and ABMR—give practically the same results provided that all shielding corrections are properly made.

A Police and Insurance Joint Management System Based on High Precision BDS/GPS Positioning
Authors: Zuo Wenwei , Guo Chi , Liu Jingnan , Peng Xuan , Yang Min
Published: January 2018

Car ownership in China reached 194 million vehicles at the end of 2016. The traffic congestion index (TCI) exceeds 2.0 during rush hour in some cities. Inefficient processing for minor traffic accidents is considered to be one of the leading causes for road traffic jams. Meanwhile, the process after an accident is quite troublesome. The main reason is that it is almost always impossible to get the complete chain of evidence when the accident happens. Accordingly, a police and insurance joint management system is developed which is based on high precision BeiDou Navigation Satellite System (BDS)/Global Positioning System (GPS) positioning to process traffic accidents. First of all, an intelligent vehicle rearview mirror terminal is developed. The terminal applies a commonly used consumer electronic device with single frequency navigation. Based on the high precision BDS/GPS positioning algorithm, its accuracy can reach sub-meter level in the urban areas. More specifically, a kernel driver is built to realize the high precision positioning algorithm in an Android HAL layer. Thus the third-party application developers can call the general location Application Programming Interface (API) of the original standard Global Navigation Satellite System (GNSS) to get high precision positioning results. Therefore, the terminal can provide lane level positioning service for car users. Next, a remote traffic accident processing platform is built to provide big data analysis and management. According to the big data analysis of information collected by BDS high precision intelligent sense service, vehicle behaviors can be obtained. The platform can also automatically match and screen the data that uploads after an accident to achieve accurate reproduction of the scene. Thus, it helps traffic police and insurance personnel to complete remote responsibility identification and survey for the accident. Thirdly, a rapid processing flow is established in this article to meet the requirements to quickly handle traffic accidents. The traffic police can remotely identify accident responsibility and the insurance personnel can remotely survey an accident. Moreover, the police and insurance joint management system has been carried out in Wuhan, Central China’s Hubei Province, and Wuxi, Eastern China’s Jiangsu Province. In a word, a system is developed to obtain and analyze multisource data including precise positioning and visual information, and a solution is proposed for efficient processing of traffic accidents.
Radar HRRP Target Recognition Based on Stacked Autoencoder and Extreme Learning Machine
Authors: Zhao Feixiang , Liu Yongxiang , Huo Kai , Zhang Shuanghui , Zhang Zhongshuai
Published: January 2018

A novel radar high-resolution range profile (HRRP) target recognition method based on a stacked autoencoder (SAE) and extreme learning machine (ELM) is presented in this paper. As a key component of deep structure, the SAE does not only learn features by making use of data, it also obtains feature expressions at different levels of data. However, with the deep structure, it is hard to achieve good generalization performance with a fast learning speed. ELM, as a new learning algorithm for single hidden layer feedforward neural networks (SLFNs), has attracted great interest from various fields for its fast learning speed and good generalization performance. However, ELM needs more hidden nodes than conventional tuning-based learning algorithms due to the random set of input weights and hidden biases. In addition, the existing ELM methods cannot utilize the class information of targets well. To solve this problem, a regularized ELM method based on the class information of the target is proposed. In this paper, SAE and the regularized ELM are combined to make full use of their advantages and make up for each of their shortcomings. The effectiveness of the proposed method is demonstrated by experiments with measured radar HRRP data. The experimental results show that the proposed method can achieve good performance in the two aspects of real-time and accuracy, especially when only a few training samples are available.
Separable Reversible Data Hiding in Encrypted Signals with Public Key Cryptography
Authors: Tai Wei-Liang , Chang Ya-Fen
Published: January 2018

We propose separable reversible data hiding in an encrypted signal with public key cryptography. In our separable framework, the image owner encrypts the original image by using a public key. On receipt of the encrypted signal, the data-hider embeds data in it by using a data-hiding key. The image decryption and data extraction are independent and separable at the receiver side. Even though the receiver, who has only the data-hiding key, does not learn about the decrypted content, he can extract data from the received marked encrypted signal. However, the receiver who has only the private key cannot extract the embedded data, but he can directly decrypt the received marked encrypted signal to obtain the original image without any error. Compared with other schemes using a cipher stream to encrypt the image, the proposed scheme is more appropriate for cloud services without degrading the security level.
Higher Spin Superfield Interactions with the Chiral Supermultiplet: Conserved Supercurrents and Cubic Vertices
Authors: Buchbinder Ioseph , Gates S. , Koutrolikos Konstantinos
Published: January 2018

We investigate cubic interactions between a chiral superfield and higher spin superfields corresponding to irreducible representations of the 4 D , N = 1 super-Poincaré algebra. We do this by demanding an invariance under the most general transformation, linear in the chiral superfield. Following Noether’s method we construct an infinite tower of higher spin supercurrent multiplets which are quadratic in the chiral superfield and include higher derivatives. The results are that a single, massless, chiral superfield can couple only to the half-integer spin supermultiplets ( s + 1 , s + 1 / 2 ) and for every value of spin there is an appropriate improvement term that reduces the supercurrent multiplet to a minimal multiplet which matches that of superconformal higher spins. On the other hand a single, massive, chiral superfield can couple only to higher spin supermultiplets of type ( 2 l + 2 , 2 l + 3 / 2 ) (only odd values of s, s = 2 l + 1 ) and there is no minimal multiplet. Furthermore, for the massless case we discuss the component level higher spin currents and provide explicit expressions for the integer and half-integer spin conserved currents together with a R-symmetry current.
Effect of Limb Position at the Time of Skin Marker Application on Sagittal Plane Kinematics of the Dog
Authors: Kim Sun-Young , Torres Bryan , Sandberg Gabriella , Budsberg Steven
Published: January 2018

Objectives To evaluate the effect of limb position during initial skin marker application on sagittal plane kinematics of the hindlimb.

Methods Six healthy dogs (20–30 kg) were evaluated. An established two-dimensional kinematic model of the pelvic limb was utilized to describe sagittal plane motion. Kinematic markers were applied separately for each dog while standing in three different positions: (1) the limb extended cranially, (2) a normal standing limb position and (3) the limb extended caudally. Following marker application at each of the three positions, dynamic gait was recorded at a walk (velocity, 0.9–1.2 m/s; acceleration, 0.5m/s2). Five valid trials were used for comparison. Complete waveform analysis was performed with generalized indicator function analysis (GIFA). Maximum and minimum joint angles and joint range of motion were compared with a one-way repeated measures ANOVA with significance at p < 0.05.

Results Significant differences were found between stifle waveforms. No differences were found between the hip or tarsus waveforms. Minimum and maximum joint angles were significantly different for the hip and stifle but not for the tarsus. No differences were found between ranges of motion for any joint evaluated.

Clinical Significance Limb position at the time of skin marker application affects gait data and is an important consideration for kinematic analysis of the hindlimb in dogs.

Objectives To assess screw loosening and pelvic narrowing following the use of locking implants to stabilise ilial body fractures in cats and small dogs.

Methods Review of clinical records and post operative and follow up radiography of 12 cats and five small dogs to evaluate accuracy of fracture reduction, screw purchase and subsequent screw loosening and reduction in pelvic diameter.

Results No screw loosening or reduction in pelvic diameter was observed at follow up.

Clinical Significance Locking T-plates may prevent complications reported following the use of conventional implant systems for the repair of ilial fractures in cats and small dogs.
Variation in the Quantity of Elastic Fibres with Degeneration in Canine Cranial Cruciate Ligaments from Labrador Retrievers
Authors: Smith Kinley , Hayashi Kei , Clements Dylan , Clegg Peter , Innes John , Comerford Eithne
Published: January 2018

Objectives This study aims to quantify numbers of elastic fibres in cranial cruciate ligaments from a dog breed at high risk of cranial cruciate ligament disease.

Methods Macroscopically normal cranial cruciate ligaments were harvested from six Labrador retrievers. Sequential histological sections were assessed for extracellular matrix degeneration (haematoxylin and eosin stain) and elastic fibre staining (Miller’s stain). Elastic fibres were semi-quantified using previously published scoring systems. Each section was scored twice by two observers.

Results Increased numbers of elastic fibres were seen with increasing cranial cruciate ligament degeneration (p = 0.001). Labrador retriever cranial cruciate ligaments had lower elastic fibre staining when compared with previous published findings in the racing greyhound.

Clinical Significance The cranial cruciate ligaments from a dog breed at high risk of cranial cruciate ligament disease vary in the quantity of elastic fibres in association with ligament degeneration. Breed variation in the quantity of elastic fibres may reflect differing risk of cranial cruciate ligament disease.
Fluorescent nucleobase analogues for base–base FRET in nucleic acids: synthesis, photophysics and applications
Authors: Bood Mattias , Sarangamath Sangamesh , Wranne Moa S , Grøtli Morten , Wilhelmsson L Marcus
Published: January 2018

Förster resonance energy transfer (FRET) between a donor nucleobase analogue and an acceptor nucleobase analogue, base–base FRET, works as a spectroscopic ruler and protractor. With their firm stacking and ability to replace the natural nucleic acid bases inside the base-stack, base analogue donor and acceptor molecules complement external fluorophores like the Cy-, Alexa- and ATTO-dyes and enable detailed investigations of structure and dynamics of nucleic acid containing systems. The first base–base FRET pair, tCO–tCnitro, has recently been complemented with among others the adenine analogue FRET pair, qAN1–qAnitro, increasing the flexibility of the methodology. Here we present the design, synthesis, photophysical characterization and use of such base analogues. They enable a higher control of the FRET orientation factor, κ2, have a different distance window of opportunity than external fluorophores, and, thus, have the potential to facilitate better structure resolution. Netropsin DNA binding and the B-to-Z-DNA transition are examples of structure investigations that recently have been performed using base–base FRET and that are described here. Base–base FRET has been around for less than a decade, only in 2017 expanded beyond one FRET pair, and represents a highly promising structure and dynamics methodology for the field of nucleic acids. Here we bring up its advantages as well as disadvantages and touch upon potential future applications.
Factors Affecting University Students Intentions to Use Debit Card Services: an Empirical Study Based on UTAUT
Authors: Kissi Philip , Oluwatobiloba Mustapha , Berko Amankwah
Published: January 2018

Despite the promising use of debit cards for e‐payment and online transactions, to the best of our knowledge, there has not been any study regarding students’ intentions to use debit card services in Nigeria. This research aims to examine factors that influence university students’ decision to use debit card services in Nigeria. A Unified Theory of Acceptance and Use of Technology (UTAUT) integrated with the trust of bank and online transaction factors are used in the study. Data were purposively selected from 400 students in the Faculty of Business Administration in Nigeria University using a survey questionnaire. The multiple linear regression results reveal that social influence, the trust of online transaction and performance expectancy exert significant influences on students’ behavioural intention to use a debit card. However, the insignificant results obtained for effort expectation and facilitating condition warrant for further investigation. We have confidence that the findings of this study will guide debit card services providers and professionals in the field in improving and promoting debit card services by revealing the students’ priorities regarding debit card services in Africa, particularly in Nigeria.
The Taurus Boundary of Stellar/Substellar (TBOSS) Survey. II. Disk Masses from ALMA Continuum Observations

Published: January 2018

We report 885 μm ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary with spectral types from M4 to M7.75. Of the 24 systems, 22 are detected at levels ranging from 1.0 to 55.7 mJy. The two nondetections are transition disks, though other transition disks in the sample are detected. Converting ALMA continuum measurements to masses using standard scaling laws and radiative transfer modeling yields dust mass estimates ranging from ∼0.3 to 20 M
⊕. The dust mass shows a declining trend with central object mass when combined with results from submillimeter surveys of more massive Taurus members. The substellar disks appear as part of a continuous sequence and not a distinct population. Compared to older Upper Sco members with similar masses across the substellar limit, the Taurus disks are brighter and more massive. Both Taurus and Upper Sco populations are consistent with an approximately linear relationship in M
dust to M
star, although derived power-law slopes depend strongly upon choices of stellar evolutionary model and dust temperature relation. The median disk around early-M stars in Taurus contains a comparable amount of mass in small solids as the average amount of heavy elements in Kepler planetary systems on short-period orbits around M-dwarf stars, with an order of magnitude spread in disk dust mass about the median value. Assuming a gas-to-dust ratio of 100:1, only a small number of low-mass stars and brown dwarfs have a total disk mass amenable to giant planet formation, consistent with the low frequency of giant planets orbiting M dwarfs.
Cosmic Microwave Background Mapmaking with a Messenger Field
Authors: Huffenberger Kevin M. , Næss Sigurd K.
Published: January 2018

We apply a messenger field method to solve the linear minimum-variance mapmaking equation in the context of Cosmic Microwave Background (CMB) observations. In simulations, the method produces sky maps that converge significantly faster than those from a conjugate gradient descent algorithm with a diagonal preconditioner, even though the computational cost per iteration is similar. The messenger method recovers large scales in the map better than conjugate gradient descent, and yields a lower overall χ
2. In the single, pencil beam approximation, each iteration of the messenger mapmaking procedure produces an unbiased map, and the iterations become more optimal as they proceed. A variant of the method can handle differential data or perform deconvolution mapmaking. The messenger method requires no preconditioner, but a high-quality solution needs a cooling parameter to control the convergence. We study the convergence properties of this new method and discuss how the algorithm is feasible for the large data sets of current and future CMB experiments.

The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides spectroscopic information of regions of the inner Milky Way, which are inaccessible to optical surveys. We present the first large study of the metallicity distribution of the innermost Galactic regions based on high-quality measurements for 7545 red giant stars within 4.5 kpc of the Galactic center, with the goal to shed light on the structure and origin of the Galactic bulge. Stellar metallicities are found, through multiple Gaussian decompositions, to be distributed in several components, which is indicative of the presence of various stellar populations such as the bar or the thin and the thick disks. Super-solar ([Fe/H] = +0.32) and solar ([Fe/H] = +0.00) metallicity components, tentatively associated with the thin disk and the Galactic bar, respectively, seem to be major contributors near the midplane. A solar-metallicity component extends outwards in the midplane but is not observed in the innermost regions. The central regions (within 3 kpc of the Galactic center) reveal, on the other hand, the presence of a significant metal-poor population ([Fe/H] = −0.46), tentatively associated with the thick disk, which becomes the dominant component far from the midplane (

kpc). Varying contributions from these different components produce a transition region at +0.5 kpc

, characterized by a significant vertical metallicity gradient.
Circumnuclear Multi-phase Gas in the Circinus Galaxy. I. Non-LTE Calculations of CO Lines
Authors: Wada Keiichi , Fukushige Ryosuke , Izumi Takuma , Tomisaka Kohji
Published: January 2018

In this study, we investigate the line emissions from cold molecular gas based on our previous “radiation-driven fountain model,” which reliably explains the spectral energy distribution of the nearest type 2 Seyfert galaxy, the Circinus galaxy. Using a snapshot of the best-fit radiation-hydrodynamic model for the central

pc, in which non-equilibrium X-ray-dominated region chemistry is solved, we conduct post-processed non-local thermodynamic equilibrium radiation transfer simulations for the CO lines. We obtain a spectral line energy distribution with a peak around

exhibits a large dispersion of more than one order of magnitude, reflecting the non-uniform internal structure of a “torus.” In addition, we found that the physical conditions differ between grid cells on a scale of a few parsecs along the observed lines of sight; therefore, a specific observed line ratio does not necessarily represent a single physical state of the interstellar medium.
X-Ray Observations of Magnetar SGR 0501+4516 from Outburst to Quiescence
Authors: Mong Y.-L. , Ng C.-Y.
Published: January 2018

Magnetars are neutron stars having extreme magnetic field strengths. Study of their emission properties in quiescent state can help understand effects of a strong magnetic field on neutron stars. SGR 0501+4516 is a magnetar that was discovered in 2008 during an outburst, which has recently returned to quiescence. We report its spectral and timing properties measured with new and archival observations from the Chandra X-ray Observatory, XMM-Newton, and Suzaku. We found that the quiescent spectrum is best fit by a power-law plus two blackbody model, with temperatures of kT
low ∼ 0.26 keV and kT
high ∼ 0.62 keV. We interpret these two blackbody components as emission from a hotspot and the entire surface. The hotspot radius shrunk from 1.4 km to 0.49 km since the outburst, and there was a significant correlation between its area and the X-ray luminosity, which agrees well with the prediction by the twisted magnetosphere model. We applied the two-temperature spectral model to all magnetars in quiescence and found that it could be a common feature among the population. Moreover, the temperature of the cooler blackbody shows a general trend with the magnetar field strength, which supports the simple scenario of heating by magnetic field decay.
Radio Evolution of Supernova Remnants Including Nonlinear Particle Acceleration: Insights from Hydrodynamic Simulations
Authors: Pavlović Marko Z. , Urošević Dejan , Arbutina Bojan , Orlando Salvatore , Maxted Nigel , Filipović Miroslav D.
Published: January 2018

We present a model for the radio evolution of supernova remnants (SNRs) obtained by using three-dimensional hydrodynamic simulations coupled with nonlinear kinetic theory of cosmic-ray (CR) acceleration in SNRs. We model the radio evolution of SNRs on a global level by performing simulations for a wide range of the relevant physical parameters, such as the ambient density, supernova (SN) explosion energy, acceleration efficiency, and magnetic field amplification (MFA) efficiency. We attribute the observed spread of radio surface brightnesses for corresponding SNR diameters to the spread of these parameters. In addition to our simulations of Type Ia SNRs, we also considered SNR radio evolution in denser, nonuniform circumstellar environments modified by the progenitor star wind. These simulations start with the mass of the ejecta substantially higher than in the case of a Type Ia SN and presumably lower shock speed. The magnetic field is understandably seen as very important for the radio evolution of SNRs. In terms of MFA, we include both resonant and nonresonant modes in our large-scale simulations by implementing models obtained from first-principles, particle-in-cell simulations and nonlinear magnetohydrodynamical simulations. We test the quality and reliability of our models on a sample consisting of Galactic and extragalactic SNRs. Our simulations give Σ − D slopes between −4 and −6 for the full Sedov regime. Recent empirical slopes obtained for the Galactic samples are around −5, while those for the extragalactic samples are around −4.
A Pharmacokinetic/Viral Kinetic Model to Evaluate Treatment of Chronic HCV Infection with a Non-Nucleoside Polymerase Inhibitor
Authors: Canini Laetitia , Lemenuel-Diot Annabelle , Brennan Barbara J , Smith Patrick F , Perelson Alan S
Published: January 2018

Background

Viral kinetic models have proven useful in characterizing treatment effectiveness during HCV therapy with interferon (IFN) as well as with direct-acting antivirals (DAAs).

Methods

Here we use a pharmacokinetic/viral kinetic (PK/VK) model to describe HCV RNA kinetics during treatment with setrobuvir, a non-nucleosidic inhibitor of the HCV NS5B polymerase enzyme. Using PK data from three studies in healthy volunteers and PK and VK data from a Phase I study, where setrobuvir was administered for 3 days, we fitted a two-compartment PK model with first-order absorption and lag-time, an Emax pharmacodynamics model and a standard biphasic VK model.

Results

Setrobuvir's EC50 and Hill coefficient and the viral clearance rate were significantly different ( P=0.014, P<0.001 and P=0.004, respectively) between patients infected with HCV subtypes 1b and 1a, leading to an increased viral load decline in patients infected with genotype 1b virus.

Conclusions

Understanding the combined effects of PK/VK on the performance of a non-nucleoside polymerase inhibitor such as setrobuvir could provide valuable insights into their use in combination with other DAAs as well as to optimize future therapy. Further, our work suggests that patients infected with subtype 1a would need higher doses than those infected with subtype 1b to achieve the same effectiveness. Whether this is true for other non-nucleoside polymerase inhibitors needs to be examined.

Associations et pouvoirs publics : vers une convergence des modèles en Europe
Authors: Archambault Édith
Published: January 2018

Résumé Il existe un modèle européen de secteur sans but lucratif différent de son homologue américain dans sa forme et ses relations avec les pouvoirs publics. Le modèle européen peut se décliner en cinq variantes : anglo-saxonne (ou libérale), corporatiste (ou partenariat rhénan), nordique (ou socio-démocrate), méditerranéenne et post-communiste. Ces variantes ont commencé à se rapprocher au cours des premières années du XXI e siècle. Ce rapprochement s’est accéléré pendant les années tourmentées qui ont suivi la crise financière de 2007. Enfin, il semble que la France, pays hybride et difficile à classer, peut tirer de ses homologues étrangers des enseignements sur les relations qu’entretiennent les pouvoirs publics nationaux et locaux avec les associations.
Les partenariats entre secteur public et fondations philanthropiques au Québec : genèse, contestation et épilogue d’une réforme de l’action publique
Authors: Lefèvre Sylvain , Berthiaume Annabelle
Published: January 2018

Résumé Depuis une dizaine d’années, un acteur joue un rôle pivot dans les relations entre l’État et le milieu associatif, au Québec: les fondations philanthropiques. Au coeur de ces nouveaux liens, se trouvent des partenariats formels, comme ceux créés dans le domaine de l’action sociale entre le gouvernement québécois et la Fondation Lucie et André Chagnon. Ces ententes ont réactivé certaines tensions liées à la revendication d’autonomie des associations. Mais à l’heure de l’austérité budgétaire, des fondations soulignent aussi le risque d’un recul de l’État social. L’article met ainsi en lumière les relations fluctuantes et les débats sur le rôle respectif de l’État, des fondations philanthropiques et des associations.
The “big society” in the United Kingdom: privatisation or democratisation of public services
Authors: Balazard Hélène , Fisher Robert , Scott Matt
Published: January 2018

Le projet de Big Society a été l’une des trois priorités du Premier ministre David Cameron après son élection en 2010. Rarement un gouvernement n’avait donné une telle importance à la société civile et aux communautés locales. L’article retrace l’évolution de cette politique publique opaque et finalement abandonnée. Une attention particulière est accordée au rôle du Community Organisers Progamme, l’un des volets les plus abouti, mais tout aussi ambigu, au sein du projet de Big Society. L’article présente une analyse critique de l’efficacité atteinte par ce projet en particulier quant à son objectif déclaré d’assurer un renforcement durable de la participation des citoyens à la gouvernance locale en accordant un rôle plus important à la société civile.
De l’économie sociale « historique » à « l’économie sociale et solidaire » : une nouvelle configuration des relations entre monde associatif et collectivités publiques
Authors: Hély Matthieu
Published: January 2018

La loi Hamon de 2014 a créé un cadre juridique instituant une forme spécifique d’entreprise, relevant de l’économie sociale et solidaire, dont l’objet fondateur poursuit une utilité sociale. L’adoption de cette loi converge avec un changement de définition du rôle de la société civile qui est mobilisée, à l’initiative des collectivités publiques, au service de politiques publiques dans de nombreux domaines (cohésion sociale, insertion, éducation, environnement, culture, etc .). Il convient donc de différencier les pratiques appartenant à l’économie sociale, au sens du mouvement historique ayant émergé au début du XIX e siècle de celles relevant désormais de l’économie sociale et solidaire entendue comme acteur de référence en matière d’innovation sociale et transcendant les frontières du public et du privé.
La réforme des rythmes scolaires, ou quand les associations font la loi et (dé)font le travail dans les services publics ?
Authors: Lebon Francis , Simonet Maud
Published: January 2018

Résumé En partie construite par la mobilisation des grandes associations d’éducation populaire et des réseaux éducatifs des collectivités locales, la réforme des rythmes scolaires ne reconnaît pas seulement le savoir des associations, elle leur ouvre également un nouvel espace de travail au sein de l’institution scolaire. Faisant l’objet de déclinaisons locales pour le moins contrastées, la mise en œuvre de cette réforme démultiplie, en les précarisant, les figures de travailleurs dans l’école : publics ou privés, titulaires, vacataires, contractuels ou bénévoles. À ce titre, elle révèle sans doute moins une redistribution des pouvoirs de l’État central vers les acteurs associatifs et les collectivités locales qu’un nouveau maillage de gouvernementalité et de travail public diluant largement les frontières du public et du privé au cœur même du service public.
Les transformations des modes de contrôle croisés entre associations et autorités publiques dans le secteur du handicap
Authors: Robelet Magali
Published: January 2018

Résumé À partir d’une enquête menée en région Rhône-Alpes, l’article montre comment évoluent les relations de contrôle croisées entre opérateurs associatifs et autorités publiques dans le secteur du handicap. À des relations marquées par les connaissances personnelles et l’autorégulation succèdent – au gré de l’affirmation des dirigeants salariés dans les associations et des recompositions de l’action publique – des modalités de contrôle à distance. Cette forme de contrôle stabilise la polarisation du secteur entre grandes et petites associations et fait évoluer les relations sociales, qui s’intensifient et se diversifient tout en étant plus impersonnelles et détachées de préoccupations militantes.

En quoi ceux-ci introduisent-ils une inquiétante étrangeté dans la difficulté à repérer et différencier ce qui appartient en propre au sujet dans sa singularité et ce qui est induit par la place qu’il occupe et qui lui est assignée tant dans le groupe d’appartenance ou dans le groupe professionnel, que dans le groupe de psychothérapie, de supervision d’équipe ou d’analyse de la pratique (dont l’analyste ou les analystes eux-mêmes ne sauraient être exclus) ? Si le groupe , dans la dimension inconsciente de ses effets ouvrant sur un nécessaire décentrement épistémologique, est originairement étranger à la psychanalyse (hors la cure, appliquée) , gageons qu’en dépit des pratiques (engagées malgré tout, dans le cadre des extensions de la psychanalyse ) il reste parfois encore largement étranger au psychanalyste qui a du mal à opérer la décentration képlérienne qu’implique et exige tout travail analytique plurisubjectif. Accueillir les implications d’une réalité psychique extratopique, qui donc ne serait pas localisée tout entière dans le sujet, ne se limite pas à des aménagements méthodologiques ou à des accommodements épistémologiques, mais suppose une rupture ontologique.
Scazzicare : des rites de possession à l’analyse de groupe
Authors: Chapelier Jean-Bernard
Published: January 2018

À partir de l’exemple du tarentisme, rituel collectif de soin des difficultés psychiques (Italie du sud), et de la clinique des groupes thérapeutiques (surtout d’enfants), il sera montré comment, dans les deux cas, il y a passage du chaos originaire à la subjectivation en passant par la filiation. Ce sont essentiellement les concepts d’excitation, d’enveloppe et de contenance déclinés dans leurs différentes configurations (physique, somatique, relationnelle et psychique) qui permettent de formuler quelques hypothèses sur l’efficacité de ces deux approches. À cette occasion, la question sera posée de savoir dans quelles mesures nos cadres dispositifs sont influencés par la culture.
De l’intime intrus à l’étranger et à l’Autre de l’autre
Authors: Duez Bernard
Published: January 2018

Cet article étudie comment la rencontre avec l’étranger active chez le sujet une problématique qui relève de l’originaire et notamment de la constance du processus originaire de l’auto-engendrement du sujet en présence de l’Autre de l’autre. L’analyse d’une situation de psychodrame psychanalytique de groupe, des liens entre le groupe et le rêve, des conventions sociales du salut et de l’excuse, du récit du roman migratoire chez les migrants, montrent comment l’Imago de l’intrus est présente dans cette rencontre et comment, au-delà de l’inquiétude et de l’effroi, l’imago de l’intrus a une fonction structurante qui permet au sujet de composer avec la pulsion de mort et de s’inscrire dans une dynamique vitale. Lorsque ce travail d’auto-engendrement en présence de l’autre échoue, il montre comment des formes délétères s’installent dans la société : l’échange généralisé du dommage sous la forme de la vengeance généralisée et son organisation par des clans mafieux. Il conclut en montrant l’exigence du travail psychique suscité par cette configuration de l’auto-engendrement en présence de l’Autre de l’autre et suggère en conclusion le lien avec les conditions du travail psychanalytique.
Quand la reconnaissance de l’intimité professionnelle stimule l’accueil de l’étranger
Authors: David Catherine
Published: January 2018

Je propose une réflexion sur l’émergence de « l’étranger » dans un dispositif d’échange et d’analyse des pratiques des encadrants (cadres, directeurs) d’institutions spécialisées du point de vue de la psychosociologie d’orientation psychanalytique. Instituer ce type d’espace avec un groupe hétérogène par les statuts et les fonctions peut être vécu comme familier, mais aussi comme étranger au point d’être rejeté. L’intensité du refus m’a amené à penser une problématique autour « d’un intime professionnel » et de ses effets sur l’acceptation ou pas de l’étranger, de l’étrangeté et de l’altérité. Nous voyons en quoi la considération de cette problématique a nécessité pour des cadres intermédiaires un cheminement particulier par la construction d’un espace d’intimité professionnelle permettant la rencontre de leurs cadres internes comme préalable à un travail accueillant le directeur. Il a ouvert à l’acceptation de l’étranger et de l’altérité.
A psychoanalytical perspective on small multilingual groups: at the crossroads of political, historical, cultural, group and individual phenomena

Les petits groupes multilingues se développent avec la mondialisation, ce qui oblige les coordinateurs à accroître leurs connaissances et leurs compétences à leur sujet. Dans cet article, nous verrons la variabilité du langage comme un lien entre la vie sociale et psychique. Notre objectif est de contribuer à la compréhension de ces phénomènes et à la façon dont nous pouvons travailler dans des groupes multilingues Cet article s’appuie sur une recherche qualitative menée dans une école de portugais langue étrangère au Brésil où nous avons observé des cours et conduit des groupes opératifs. Un tel travail nous a amenés à mettre l’accent sur quatre points en travaillant avec de petits groupes multilingues : 1) les représentations de la situation multilingue et des langues spécifiques ; 2) ce qui arrive en cas d’échec à communiquer 3) les alliances et les processus d’identification et, enfin, 4) les changements de langue et les interférences au cours du groupe. Nous croyons qu’en étant attentif à ces quatre dimensions, la conduite en groupe de groupes multilingues peut être enrichie.
Un entre-soi de possédant·e·s
Authors: Bessière Céline , Gollac Sibylle
Published: January 2018

Resume Lors d'une succession ou d'un divorce, les biens qui composent l'héritage ou le patrimoine conjugal sont distribués entre héritiers et héritières ou entre ex-épouses et époux. Rarement tranchés par l'institution judiciaire, ces arrangements patrimoniaux qui concernent les fractions possédantes de la société française (propriétaires d'un bien immobilier, d'une entreprise ou d'un minimum de capitaux financiers) se déroulent principalement dans les études et cabinets de professions libérales du droit (notaires et avocat·e·s), dont les trajectoires sociales sont étroitement liées à la détention d'un patrimoine. Les discussions à huis clos des arrangements patrimoniaux, dans les offices notariaux comme dans les cabinets d'avocat·e·s, réunissent ainsi des possédant·e·s. Du côté de la clientèle comme des professionnel·le·s, cette caractéristique commune n'empêche pas une grande diversité de positions sociales et de trajectoires. Nous montrons que les notaires et avocat·e·s ne semblent jamais aussi à l'aise pour jouer avec le droit que lorsqu'il·elle·s travaillent dans l'entre-soi, avec une clientèle choisie, mettant alors à disposition de leurs client·e·s différents outils juridiques ou marges de man uvre, au service d'un intérêt partagé : celui de la reproduction du capital économique, aux dépens d'une administration fiscale domestiquée. La maîtrise du droit dont disposent certain·e·s dominant·e·s se joue en grande partie dans le rapport au capital économique qu'ils partagent avec certaines professions libérales du droit. Ce rapport commun au capital économique s'avère fortement genré, et les arrangements patrimoniaux qui émergent dans les cabinets d'avocat·e·s et les offices notariaux se font généralement au détriment des ex-épouses et des héritières.
De fausses adresses pour contourner la carte scolaire
Authors: Barrault-Stella Lorenzo
Published: January 2018

Résumé À partir d'une enquête qualitative localisée croisant entretiens répétés, observations et archives personnelles, cet article aborde les usages, par certaines fractions culturelles des classes supérieures, de fausses adresses pour contourner la carte scolaire. S'appuyant sur les sociologies du droit et de l'éducation, l'analyse revient sur les conditions sociales et contextuelles de ce type de stratégie scolaire, puis sur les ressources, les savoir-faire, les apprentissages et les démarches administratives nécessaires à la fabrique d'une fausse adresse. L'enquête apporte une contribution à l'étude des rapports ambivalents au droit et à l'État de groupes suffisamment dotés pour s'accommoder avec succès des règles juridiques.

The need of high performance integrated circuits and high power density communication devices drives the development of materials enhancing the conductive performances by carbon nanoparticles. Among nanocomposites, the ternary hybrid carbon nanotubes/graphene nanoplatelets/polymer composites represent a debatable route to enhance the transport performances.
In this study hybrid ternary nanocomposites were manufactured by direct mixing of multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) at a fixed filler content (0.3 wt.%), but different relative combination, within an epoxy system. MWNT/epoxy nanocomposites were manufactured for comparison. The quality of dispersion was evaluated by optical and scanning electron microscopy (SEM). The electrical properties of hybrid composites were measured in the temperature range from 30 up to 300 K.
The synergic combination of 1D/2D particles did not interfere with the percolative behaviour of MWCNTs but improved the overall electrical performances. The addition of a small amount of GNPs (0.05 wt.%) led to a strong increment of the sample conductivity over all the temperature range, compared to that of mono filler systems.

Estudo com o objetivo de analisar a produção das equipes da Estratégia de Saúde da Família, com base em indicadores do Sistema de Informação da Atenção Básica, antes e após a implantação do Programa para Melhoria da Qualidade na Atenção Básica. Utilizou-se abordagem quantitativa, transversal, descritiva e exploratória, a partir dos Relatórios da Situação de Saúde e Acompanhamento das Famílias, referentes às equipes. Foram incluídas 112 equipes divididas em dois grupos. Realizou-se análise descritiva do conjunto de indicadores e procedeu-se a estatística exploratória e analítica para comparar as diferenças entre os grupos. Constatou-se que as equipes, independentemente de aderirem ou não ao programa, obtiveram incremento nos registros do sistema de informação, sinalizando uma sensibilização de toda a rede para melhoria dos seus registros. Apesar deste aumento, o acompanhamento das famílias não ocorreu na mesma proporção que os cadastramentos.
