De l’évaluation institutionnelle à la pédagogie inductive : l’exemple d’une recherche collaborative avec des enfants sur l’évaluation d’un dispositif éducatif
Authors: Hurtel Benoît , Chevalier Jacques M. 
Published: November 2016

Cette étude vise la description d’une expérimentation sur une nouvelle méthodologie d’évaluation utilisant des outils de collecte et d’analyse de données par une démarche inductive afin d’évaluer un programme d’initiation au scoutisme auprès d’une population de jeunes du primaire au Québec de 7 à 12 ans. Le dispositif d’évaluation mis en place porte sur deux axes. Le premier concerne le choix d’une approche participative par la mise en oeuvre de la collecte de données auprès des jeunes sous forme d’ateliers se déroulant en six étapes, facilitant le recueil de leurs discours sur des aspects spécifiques de leur vécu. Le second porte sur une approche collaborative par l’implication des jeunes dans la coconstruction de leur discours collectif. Grâce à une analyse qualitative permettant la compréhension des données verbales recueillies, il ressort six caractéristiques du « vrai scout » en lien avec l’évaluation de programme, portant sur l’importance d’être un citoyen actif et engagé dans la vie de sa communauté. Cette recherche-action favorise l’élément apprenant des jeunes du primaire par une approche inductive et met la pédagogie au coeur de cette démarche en contribuant aux objectifs du programme qu’elle évalue et en utilisant le dispositif d’évaluation participative comme une situation de découverte; « on apprend ensemble », comme le dit un des jeunes.
Analyse discursive et approche inductive : Justin Trudeau et les enjeux de pouvoir produisant le politicien célèbre
Authors: Durocher Myriam 
Published: November 2016

Cet article porte sur la méthodologie utilisée dans le cadre d’un travail de recherche inspiré descultural studiesqui visait à comprendre comment, par la représentation du politicien québécois « célèbre », se pose un ensemble d’enjeux de pouvoir qui permettent l’existence et la circulation de certaines représentations particulières du politicien. Le cas de Justin Trudeau, fortement médiatisé lors de la course à la chefferie du Parti libéral du Canada, sert d’exemple pour illustrer le propos. Après une brève présentation des principaux concepts qui sous-tendent l’ensemble du projet de recherche, l’approche inductive utilisée pour mener une analyse discursive est détaillée et illustrée, de la collecte à l’analyse des données, en passant par les difficultés rencontrées et les stratégies mises en place pour permettre une meilleure appropriation de la démarche analytique. Les résultats, ponctués de rappels du rôle joué par le processus inductif dans leur élaboration, sont également présentés.
Les archives psychiatriques : une occasion de saisir l’expérience du patient (Belgique, entre-deux-guerres)
Authors: Massin Veerle 
Published: November 2016

Cet article présente une réflexion exploratoire sur la question de l’expérience des patients placés en institution psychiatrique, dans sa dimension historique. Cette expérience est-elle saisissable, via les archives produites par l’hôpital ? La réflexion part d’une étude des circonstances de placement de femmes en psychiatrie, dans la Belgique de l’entre-deux-guerres, dont l’objectif est d’appréhender quelles sont les situations sociales, individuelles et familiales qui aboutissent à une décision d’internement en institution psychiatrique fermée. La notion d’expérience est ici mobilisée pour voir s’il est possible de comprendre la psychiatrie autrement, c’est-à-dire la comprendre comme vécu et comme fait social. Peut-on, à partir des archives psychiatriques produites par les institutions hospitalières, dépasser les questions institutionnelles et médicales, pour saisir comment la maladie mentale a été expérimentée par les personnes placées ? L’objectif de cet article est aussi de poser quelques jalons méthodologiques relatifs aux questions de l’interprétation, du vécu et de l’émotion. Cet article n’est donc pas tant un compte-rendu des résultats de la recherche menée au sein des archives psychiatriques, mais plutôt une réflexion sur la démarche et les possibilités de l’historien relativement à la question de l’expérience en psychiatrie.
La bande des six réclame plus de liberté. Délinquants juvéniles internés à Saint-Jean-de-Dieu, milieu 20e siècle
Authors: Desmeules Martin , Thifault Marie-Claude 
Published: November 2016

Au cours des dernières années, nous avons dépouillé un grand nombre de dossiers psychiatriques conservés par le Service des archives de l’Institut universitaire en santé mentale de Montréal (IUSMM). L’article ici proposé s’intéresse en particulier au document Assemblée des médecins du 12 février 1959, retrouvé dans les dossiers de six enfants illégitimes admis à l’Hôpital Saint-Jean-de-Dieu à la fin des années 1950. Inspirés des travaux de Roy Porter et de l’approche from below, nous cherchons à intégrer dans le discours historique la parole des sans-voix, plus précisément, dans le cas présent, celle d’une bande de jeunes délinquants marqués par d’impressionnants parcours transinstitutionnels.
Reconstituer une sociabilité savante à partir du fonds d’archives du Centre Hospitalier Henri Ey de Bonneval : réseaux et leurres induits par le travail archivistique
Authors: Delille Emmanuel 
Published: November 2016

Le Centre Hospitalier Henri Ey de Bonneval (Eure-et-Loir, région Centre de la France) est connu dans l’histoire de la psychiatrie pour une série de colloques qui a réuni des figures centrales du champ de la santé mentale à partir des années 1940. Leurs contributions ont donné lieu à deux volumes,Le Problème de la psychogenèse des névroses et des psychoses(1950) etL’Inconscient(1966), où l’on retrouve à la fois des exposés systématiques et une partie des débats qui animaient dans le passé les médecins psychiatres, neurologues, psychologues, psychanalystes et philosophes français. À partir des archives de la revueL’Évolution psychiatrique, nous examinerons ce réseau en nous demandant s’il peut aider à reconstituer la vie intellectuelle des psychiatres français dans la société d’après-guerre, au fil des réformes des études médicales (Réformes Debré et Faure, 1958-1968).
A sub-terahertz broadband detector based on a GaN high-electron-mobility transistor with nanoantennas

Published: November 2016

Abstract
We report a sub-terahertz (THz) detector based on a 0.25-µm-gate-length AlGaN/GaN high-electron-mobility transistor (HEMT) on a Si substrate with nanoantennas. The fabricated device shows excellent performance with a maximum responsivity (R
v) of 15 kV/W and a minimal noise equivalent power (NEP) of 0.58 pW/Hz0.5 for 0.14 THz radiation at room temperature. We consider these excellent results as due to the design of asymmetric nanoantennas. From simulation, we show that indeed such nanoantennas can effectively enhance the local electric field induced by sub-THz radiation and thereby improve the detection response. The excellent results indicate that GaN HEMTs with nanoantennas are future competitive detectors for sub-THz and THz imaging applications.

Published: November 2016

Abstract
We report the thermoelectric properties of WS2 nanotube networks. By using electrolyte-gating techniques, we turned on a conducting channel in the macroscopic networks of WS2 nanotubes in both the hole and electron regions and evaluated the thermoelectric properties of the networks. We manipulated the P- and N-type Seebeck coefficients in the WS2 nanotube networks by changing the shifts in the gate voltage potentials. The power factor of the WS2 nanotube networks increased as the gate voltage shifted and exhibited a high thermoelectric performance approaching that of single-crystalline WS2 flakes.
High figure-of-merit compact phase shifters based on liquid crystal material for 1–10 GHz applications
Authors: Cai Longzhu , Xu Huan , Li Jinfeng , Chu Daping 
Published: November 2016

Abstract
A liquid crystal (LC) based tunable microstrip line (ML) phase shifter featuring high performance is presented. The experimental results show an electrically tunable differential phase up to 360° at 10 GHz with an overall insertion loss <8.5 dB. The device possesses a high figure-of-merit (FoM) of 64°/dB at 9.8 GHz and 60°/dB between 7–10 GHz. This is achieved by simultaneously considering both of the LC tuned phase and overall loss in the design. The proposed device utilizes the inverted meander ML technology to minimize its size. Taking into account the real fabrication procedure, a novel impedance matching structure is applied, and the measured return loss is considerably improved. The FoM and phase tuning property of the fabricated device as optimized are compared with the state-of-art results published recently and show better performance for both of them.

Published: November 2016

Background
Epidemiological evidence indicates epilepsy is more common in patients with autism spectrum disorders (ASD) (20–25%) than in the general population. The aim of this project was to analyze seizure susceptibility in developing rats prenatally exposed to valproic acid (VPA) as autism model.

Methods
Pregnant females were injected with VPA during the twelfth embryonic day. Seizures were induced in fourteen-days-old rat pups using two models of convulsions: pentylenetetrazole (PTZ) and lithium-pilocarpine (Li-Pilo).

Results
Two subgroups with different PTZ-induced seizure susceptibility in rats exposed to VPA were found: a high susceptibility (VPA+) (28/42, seizure severity 5) and a low susceptibility (VPA−) (14/42, seizure severity 2). The VPA+ subgroup exhibited an increased duration of the generalized tonic-clonic seizure (GTCS; 45 ± 2.7 min), a higher number of rats showed several GTCS (14/28) and developed status epilepticus (SE) after PTZ injection (19/27) compared with control animals (36.6 ± 1.9 min; 10/39; 15/39, respectively). No differences in seizure severity, latency or duration of SE induced by Li-Pilo were detected between VPA and control animals.

Discussion
Prenatal VPA modifies the susceptibility to PTZ-induced seizures in developing rats, which may be linked to an alteration in the GABAergic transmission. These findings contribute to a better understanding of the comorbidity between autism and epilepsy.
Quantitative analysis of rat adipose tissue cell recovery, and non-fat cell volume, in primary cell cultures

Published: November 2016

BackgroundWhite adipose tissue (WAT) is a complex, diffuse, multifunctional organ which contains adipocytes, and a large proportion of fat, but also other cell types, active in defense, regeneration and signalling functions. Studies with adipocytes often require their isolation from WAT by breaking up the matrix of collagen fibres; however, it is unclear to what extent adipocyte number in primary cultures correlates with their number in intact WAT, since recovery and viability are often unknown.Experimental DesignEpididymal WAT of four young adult rats was used to isolate adipocytes with collagenase. Careful recording of lipid content of tissue, and all fraction volumes and weights, allowed us to trace the amount of initial WAT fat remaining in the cell preparation. Functionality was estimated by incubation with glucose and measurement of glucose uptake and lactate, glycerol and NEFA excretion rates up to 48 h. Non-adipocyte cells were also recovered and their sizes (and those of adipocytes) were measured. The presence of non-nucleated cells (erythrocytes) was also estimated.ResultsCell numbers and sizes were correlated from all fractions to intact WAT. Tracing the lipid content, the recovery of adipocytes in the final, metabolically active, preparation was in the range of 70–75%. Cells showed even higher metabolic activity in the second than in the first day of incubation. Adipocytes were 7%, erythrocytes 66% and other stromal (nucleated cells) 27% of total WAT cells. However, their overall volumes were 90%, 0.05%, and 0.2% of WAT. Non-fat volume of adipocytes was 1.3% of WAT.ConclusionsThe methodology presented here allows for a direct quantitative reference to the original tissue of studies using isolated cells. We have also found that the “live cell mass” of adipose tissue is very small: about 13 µL/g for adipocytes and 2 µL/g stromal, plus about 1 µL/g blood (the rats were killed by exsanguination). These data translate (with respect to the actual “live cytoplasm” size) into an extremely high metabolic activity, which make WAT an even more significant agent in the control of energy metabolism.
The effectiveness of cooling conditions on temperature of canine EDTA whole blood samples

Published: November 2016

BackgroundPreanalytic factors such as time and temperature can have significant effects on laboratory test results. For example, ammonium concentration will increase 31% in blood samples stored at room temperature for 30 min before centrifugation. To reduce preanalytic error, blood samples may be placed in precooled tubes and chilled on ice or in ice water baths; however, the effectiveness of these modalities in cooling blood samples has not been formally evaluated. The purpose of this study was to evaluate the effectiveness of various cooling modalities on reducing temperature of EDTA whole blood samples.MethodsPooled samples of canine EDTA whole blood were divided into two aliquots. Saline was added to one aliquot to produce a packed cell volume (PCV) of 40% and to the second aliquot to produce a PCV of 20% (simulated anemia). Thirty samples from each aliquot were warmed to 37.7 °C and cooled in 2 ml allotments under one of three conditions: in ice, in ice after transfer to a precooled tube, or in an ice water bath. Temperature of each sample was recorded at one minute intervals for 15 min.ResultsWithin treatment conditions, sample PCV had no significant effect on cooling. Cooling in ice water was significantly faster than cooling in ice only or transferring the sample to a precooled tube and cooling it on ice. Mean temperature of samples cooled in ice water was significantly lower at 15 min than mean temperatures of those cooled in ice, whether or not the tube was precooled. By 4 min, samples cooled in an ice water bath had reached mean temperatures less than 4 °C (refrigeration temperature), while samples cooled in other conditions remained above 4.0 °C for at least 11 min. For samples with a PCV of 40%, precooling the tube had no significant effect on rate of cooling on ice. For samples with a PCV of 20%, transfer to a precooled tube resulted in a significantly faster rate of cooling than direct placement of the warmed tube onto ice.DiscussionCanine EDTA whole blood samples cool most rapidly and to a greater degree when placed in an ice-water bath rather than in ice. Samples stored on ice water can rapidly drop below normal refrigeration temperatures; this should be taken into consideration when using this cooling modality.
Diskrete Silber(I)‐Palladium(II)‐Oxo‐Nanocluster, {Ag4Pd13} und {Ag5Pd15}, sowie die Rolle der Metall‐Metall‐Bindung induziert durch Kationen‐Einschluss

AbstractDie beiden diskreten Silber(I)‐Palladium(II)‐Oxo‐Nanocluster {Ag4Pd13} und {Ag5Pd15} sind die ersten Beispiele von edelmetallverkappten Polyoxoedelmetallaten mit einem neuartigen Wirt‐Gast‐Bindungsmodus, der hetero‐ und homometallische Ag‐Pd‐ und Ag‐Ag‐Wechselwirkungen beinhaltet. Umfassende theoretische Studien deuten darauf hin, dass die Ag‐Pd‐Metallbindungen teilweise von einem Polyanion‐Oberflächeneffekt auf die AgI‐Gastionen herrühren, der durch starke elektrostatische Kräfte induziert wird. Diese Arbeit eröffnet ein Gebiet komplett anorganischer Silber‐Palladium‐Oxo‐Nanocluster, die als Vorstufen für die Bildung monodisperser Kern‐Schale‐Nanopartikel angesehen werden können, welche eine hohe Relevanz im Bereich der Katalyse haben.
Modification of Bi2WO6 composites with rGO for enhanced visible light driven NO removal
Authors: Wang L. , Sun B. , Wang W. , Feng L. , Li Q. , Li C. 
Published: November 2016

AbstractBi2WO6‐rGO composites were synthesized through hydrothermal method. Its visible‐light‐driven photocatalytic properties were evaluated by the oxidation of nitrogen monoxide, which exhibited significantly enhancement on the photocatalytic performance comparing with Bi2WO6. Bi2WO6–2% rGO showed the highest photocatalytic activity for NO removal. The enhanced photocatalytic activity can be attributed to the increased light absorption and more effective charge transportation and separation arisen from the strong chemical bonding between Bi2WO6 and rGO. The results on the effects of H2O and SO2 concentration to NO removal efficiency indicate that the activity of Bi2WO6–2% rGO composite was suppressed by the coexisting of SO2 while promoted by H2O. In addition, the reaction mechanism of the photocatalytic oxidation of NO to NO2 was also discussed. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.

Published: November 2016

ABSTRACTAn antifouling surface is highly desirable for many biomedical applications. In this study, poly(vinyl chloride) (PVC) films were endowed with the improved properties of resisting nonspecific protein adsorption and platelet adhesion simply through being coated with a kind of mixed‐charge zwitterionic polymer, poly(3‐sulfopropyl methacrylate–methacrylatoethyl trimethyl ammonium chloride–glycidyl methacrylate) (PSTG), with random moieties of negatively charged 3‐sulfopropyl methacrylate potassium, positively charged [2‐(methacryloyloxy)‐ethyl] trimethylammonium chloride, and glycidyl methacrylate. The PSTG‐grafted PVC films were formed by the simple immersion of an amino‐functionalized PVC film into a PSTG solution. A grafting density of 220.84 µg/cm2 of PSTG4‐grafted PVC film was successfully obtained. The PSTG4‐grafted PVC film showed a lower contact angle (37.5 °) than the ungrafted PVC film (98.3 °). The in vitro protein adsorption results show that the bovine serum albumin adsorption amount decreased 6.72 µg/cm2 in the case of the PSTG4‐grafted PVC film, whereas that on the ungrafted PVC film was 28.54 µg/cm2. So, PSTG‐grafted PVC films could be promising materials for medical devices. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44632.
Comparison of thermoset soy protein resin toughening by natural rubber and epoxidized natural rubber
Authors: Kim Joo Ran , Netravali Anil N. 
Published: November 2016

ABSTRACTFully bio‐based soy protein isolate (SPI) resins were toughened using natural rubber (NR) and epoxidized natural rubber (ENR). Resin compositions containing up to 30 wt % NR or ENR were prepared and characterized for their physical, chemical and mechanical properties. Crosslinking between SPI and ENR was confirmed using 1H‐NMR and ATR‐FTIR. All SPI/NR resins exhibited two distinctive drops in their modulus at glass transition temperature (Tg) and degradation temperature (Td) at around −50 and 215 °C, corresponding to major segmental motions of NR and SPI, respectively. SPI/ENR resins showed similar Tg and Td transitions at slightly higher temperatures. For SPI/ENR specimens the increase in ENR content from 0 to 30 wt % showed major increase in Tg from −23 to 13 °C as a result of crosslinking between SPI and ENR. The increase in ENR content from 0 to 30 wt % increased the fracture toughness from 0.13 to 1.02 MPa with minimum loss of tensile properties. The results indicated that ENR was not only more effective in toughening SPI than NR but the tensile properties of SPI/ENR were also significantly higher than the corresponding compositions of SPI/NR. SPI/ENR green resin with higher toughness could be used as fully biodegradable thermoset resin in many applications including green composites. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Unprecedented Reaction Pathway of Sterically Crowded Calcium Complexes: Sequential C−N Bond Cleavage Reactions Induced by C−H Bond Activations
Authors: Yang Yang , Wang Haobing , Ma Haiyan 
Published: November 2016

AbstractFive bis(quinolylmethyl)‐(1H‐indolylmethyl)amine (BQIA) compounds, that is, {(quinol‐8‐yl‐CH2)2NCH2(3‐Br‐1H‐indol‐2‐yl)} (L1H) and {[(8‐R3‐quinol‐2‐yl)CH2]2NCH(R2)[3‐R1‐1H‐indol‐2‐yl]} (L2–5H) (L2H: R1=Br, R2=H, R3=H; L3H: R1=Br, R2=H, R3=iPr; L4H: R1=H, R2=CH3, R3=iPr; L5H: R1=H, R2=nBu, R3=iPr) were synthesized and used to prepare calcium complexes. The reactions of L1–5H with silylamido calcium precursors (Ca[N(SiMe2R)2]2(THF)2, R=Me or H) at room temperature gave heteroleptic products (L1, 2)CaN(SiMe3)2 (1, 2), (L3, 4)CaN(SiHMe2)2 (3 a, 4 a) and homoleptic complexes (L3, 5)2Ca (D3, D5). NMR and X‐ray analyses proved that these calcium complexes were stabilized through Ca⋅⋅⋅C−Si, Ca⋅⋅⋅H−Si or Ca⋅⋅⋅H−C agostic interactions. Unexpectedly, calcium complexes ((L3–5)CaN(SiMe3)2) bearing more sterically encumbered ligands of the same type were extremely unstable and underwent C−N bond cleavage processes as a consequence of intramolecular C−H bond activation, leading to the exclusive formation of (E)‐1,2‐bis(8‐isopropylquinol‐2‐yl)ethane.

Published: November 2016

AbstractThe invention of corner units was the key factor that allowed the synthesis of cyclo‐para‐phenylenes with strained curved π‐systems. Despite only a few scarce instances of the development of corner units to date, a variety of structural congeners have been synthesized. These preceding corner units commonly possessed directing angles of ≤90°, which enabled the macrocyclization of multiple units, up to six. In this study, we introduce an obtuse‐angled corner unit for the synthesis of cyclo‐para‐phenylene congeners. The corner unit with oxanorbornadiene possessed a directing angle of 126° and thus allowed for the macrocyclization of larger structures with up to seven units. Reductive aromatization was applicable to complete the cyclo‐para‐phenylene structures and afforded the congeners with multiple anthracenylene panels. Structural studies with experimental and theoretical methods revealed a fluctuating structure with an intrinsic non‐belt shape.
