Ethnographie d’un dispositif opérateur de l’interculturalité au Centre culturel oecuménique (CCO) de Villeurbanne : un processus de patrimonialisation original?
Authors: Aubry Anne 
Published: June 2016

Dans la perspective de son cinquantenaire en 2013, le CCO (Centre culturel oecuménique de Villeurbanne) a engagé une recherche-action sur les dynamiques interculturelles qui l’animent. Dès lors, comment les pratiques sédimentent ce qui pourrait « faire patrimoine », institutionnalisant un lieu, des modes de faire et des valeurs de l’ordre de l’interculturel? L’ethnographie du dispositif de création artistique participative « Paroles sur place », qui a pour objectif d’amener les personnes qui y prennent part à se rencontrer et à créer de l’« en-commun » en puisant dans leurs propres ressources culturelles pour arriver à la création d’un spectacle, nous donnerait à voir les modalités particulières d’un « faire patrimoine » en interculturalité. La pratique développée ne permettrait-elle pas de saisir les dimensions prospectives du patrimoine, dont l’existence reposerait sur une dynamique de recréation constante par opération de branchements? Ne pourrait-on pas émettre l’hypothèse qu’un patrimoine puisse être « impropre », ne pas faire l’objet de propriété exclusive et que s’ouvrirait là des processus de subjectivation? Enfin, comment au travers de dynamiques de compositions, recompositions et hybridations des ressources culturelles des personnes pouvons-nous comprendre le « vivant » du patrimoine au travers d’activités sociales? La valeur serait moins intrinsèque à l’objet patrimonial en tant que tel que liée à son usage et aux échanges qu’il permet pour contribuer à un commun toujours en train de se faire, jamais complètement réalisé. Le vivant du patrimoine serait alors une préservation en interculturalité des dynamiques qui permettent de faire valeur.
La gestion de la différence culturelle par les éducateurs sociaux dans leur travail au quotidien
Authors: Gulfi Alida 
Published: June 2016

L’intervention en contexte multiculturel constitue un défi pour les éducateurs sociaux qui doivent composer avec la diversité culturelle. Cet article s’intéresse à la gestion de la différence culturelle par les éducateurs sociaux dans leur travail au quotidien. Quelle est la place qu’ils donnent à la différence culturelle dans l’intervention? Quels sont les défis qu’ils rencontrent dans l’accompagnement des usagers aux références culturelles diverses? Pour ce faire, une enquête qualitative a été conduite auprès de 24 éducateurs sociaux travaillant dans diverses institutions socio-éducatives de Suisse romande. Les résultats mettent en évidence trois types d’attitude qui caractérisent la gestion de la différence culturelle par les éducateurs sociaux : une même intervention pour tous les usagers quelle que soit leur origine, une intervention spécifique et individualisée pour chaque usager et une adaptation de l’intervention aux spécificités culturelles des usagers. De même, les résultats montrent que les éducateurs sociaux sont confrontés à plusieurs défis d’ordre personnel, relationnel et contextuel dans le travail avec la différence culturelle, notamment les relations de genre, la conception du handicap et de la maladie mentale, les modes d’éducation des enfants, les croyances et pratiques religieuses, les contraintes administratives, institutionnelles et politiques liées à l’intervention ainsi que les trajectoires migratoires des usagers et leurs familles.
The Integrated Theory of Sexual Offending–Revised
Authors: Ward Tony , Beech Anthony R. 
Published: June 2016

AbstractIn this chapter, the aim is to link together conceptually factors implicated in the occurrence of sexual abuse into a theoretical framework, what was originally called the Integrated Theory of Sexual Offending (ITSO). The ITSO is a broad aetiological framework that has the capacity to inform the construction of more specific theories of particular types of sexual offending (e.g., rape, child sexual abuse) and to unify single factor and descriptive theories within a coverall conceptual framework. According to the ITSO, sexual abuse occurs as a consequence of a number of interacting causal factors, operating at different levels and occurring in distinct domains of human functioning: biological (evolution, genetic variations, and neurobiology), ecological (social and cultural environment, personal circumstances, physical environment), core neuropsychological systems, and personal agency.
Organizing Principles for an Integrated Model of Change for the Treatment of Sexual Offending
Authors: Carter Adam J. , Mann Ruth E. 
Published: June 2016

AbstractExamination of the contents of contemporary treatment programmes for sexual offending suggests that many could benefit from greater focus upon established risk factors. After consideration of possible reasons for gaps between evidence and practice, this chapter sets out a model of change and some organizing principles. It is hoped that the overall framework proposed – model of change and associated organizing principles – will encourage debate and permit the development of a new generation of treatment programmes that adhere better to the Risk, Need, and Responsivity principles of correctional rehabilitation and the biological, psychological, and social factors that underpin sexual offending than is currently the case.
Assessment of Sexual Sadism

Published: June 2016

AbstractA brief description of the key developments of the concept of sexual sadism is followed by an introduction to the four main approaches to assessment: psychiatric diagnoses, phallometric evaluations of the offender's sexual interests, utilization of crime scene data, and a measure based on a variety of data. We point to serious problems with psychiatric diagnoses and conclude that the lack of reliability, among other problems, renders this approach problematic. To date, no fully satisfactory phallometric assessment procedure has been developed that includes the critical features of sexual violence and the humiliation and degradation of the victim. Although crime scene data can provide valuable information, these data have not yet been organized into a satisfactory coding system. However, relying on these data and other sources, we have developed a rating scale that reliably and satisfactorily discriminates sadists from other sex offenders. This measure has the additional value that it can be used categorically to provide a diagnosis and also dimensionally to identify the degree of sadism.
At Our Best
Authors: Prescott David S. 
Published: June 2016

AbstractThis chapter reviews the style, spirit, and processes of motivational interviewing, with a specific focus on working with people who have sexually abused. It defines key elements and provides case examples of them in action. Central to motivational interviewing with people who have sexually abused is the elicitation of even the smallest verbal indicators of a desire, ability, reason, or need to change. Individual micro‐skills for eliciting internal motivation to change are also explored with examples.

AbstractGlycogen synthase kinase‐3 (GSK‐3) regulates multiple cellular processes in diabetes, oncology, and neurology. N‐(3‐(1H‐1,2,4‐triazol‐1‐yl)propyl)‐5‐(3‐chloro‐4‐methoxyphenyl)oxazole‐4‐carboxamide (PF‐04802367 or PF‐367) has been identified as a highly potent inhibitor, which is among the most selective antagonists of GSK‐3 to date. Its efficacy was demonstrated in modulation of tau phosphorylation in vitro and in vivo. Whereas the kinetics of PF‐367 binding in brain tissues are too fast for an effective therapeutic agent, the pharmacokinetic profile of PF‐367 is ideal for discovery of radiopharmaceuticals for GSK‐3 in the central nervous system. A 11C‐isotopologue of PF‐367 was synthesized and preliminary PET imaging studies in non‐human primates confirmed that we have overcome the two major obstacles for imaging GSK‐3, namely, reasonable brain permeability and displaceable binding.

Published: June 2016

AbstractFacile and effective access for the asymmetric construction of the useful and important skeleton of the bicyclic N,O‐acetals is described. CuII/SaBOX could catalyze the reaction of β,γ‐unsaturated α‐ketoesters with cyclic enamines efficiently, thus affording the desired products in excellent yields with excellent stereoselectivities (21 examples; up to 99 % yields; up to >95:5 d.r.; and 95–99 % ee). This reaction can be well performed on gram scale, even with only 1 mol % catalyst loading. The single‐crystal structures of the copper complexes lead to a good understanding of the stereo‐synergistic effects of the sidearm.

AbstractEine direkte, hoch enantioselektive Synthese von Tetrahydroacridinen gelang durch Phosphorsäure‐katalysierte Addition von Enamiden an in situ erzeugte ortho‐Chinonmethidimine mit nachfolgender Eliminierung. Diese neue, einstufige Methode eröffnet einen sehr effizienten, eleganten und selektiven Zugang zu wertvollen N‐Heterocyclen mit einem 1,4‐Dihydrochinolin‐Motiv. Die Reaktionsprodukte lassen sich anschließend direkt durch diastereoselektive Hydrierung und N‐Entschützung in freie Hexahydroacridine mit insgesamt drei neuen stereogenen Zentren überführen.
Clean Donor Oxidation Enhances the H2 Evolution Activity of a Carbon Quantum Dot–Molecular Catalyst Photosystem

Published: June 2016

AbstractCarbon quantum dots (CQDs) are new‐generation light absorbers for photocatalytic H2 evolution in aqueous solution, but the performance of CQD‐molecular catalyst systems is currently limited by the decomposition of the molecular component. Clean oxidation of the electron donor by donor recycling prevents the formation of destructive radical species and non‐innocent oxidation products. This approach allowed a CQD‐molecular nickel bis(diphosphine) photocatalyst system to reach a benchmark lifetime of more than 5 days and a record turnover number of 1094±61 molH2 (molNi)−1 for a defined synthetic molecular nickel catalyst in purely aqueous solution under AM1.5G solar irradiation.
Controlling Ethylene Hydrogenation Reactivity on Pt13 Clusters by Varying the Stoichiometry of the Amorphous Silica Support

Published: June 2016

AbstractEthylene hydrogenation was investigated on size‐selected Pt13 clusters supported on three amorphous silica (a‐SiO2) thin films with different stoichiometries. Activity measurements of the reaction at 300 K revealed that on a silicon‐rich and a stoichiometric film, Pt13 exhibits a similar activity to that of Pt(111), in line with the known structure insensitivity of the reaction. On an oxygen‐rich film, a threefold increased rate was measured. Pulsing ethylene at 400 K, then measuring the activity at 300 K, resulted in complete loss of activity on the silicon‐rich surface compared to only marginal losses on the other surfaces. The measured reactivity trends correlate with charging characteristics of a Pt13 cluster on the SiO2 films, predicted through first‐principle calculations. The results reveal that the stoichiometry‐dependent charging by the support can be used to tune the selectivity of reaction pathways during a catalytic hydrogenation reaction.
Sensing Enzymatic Activity by Exposure and Selection of DNA‐Encoded Probes
Authors: Jetson Rachael R. , Krusemark Casey J. 
Published: June 2016

AbstractA sensing approach is applied to encode quantitative enzymatic activity information into DNA sequence populations. The method utilizes DNA‐linked peptide substrates as activity probes. Signal detection involves chemical manipulation of a probe population downstream of sample exposure and application of purifying, selective pressure for enzyme products. Selection‐induced changes in DNA abundance indicate sample activity. The detection of protein kinase, protease, and farnesyltransferase activities is demonstrated. The assays were employed to measure enzyme inhibition by small molecules and activity in cell lysates using parallel DNA sequencing or quantitative PCR. This strategy will allow the extensive infrastructure for genetic analysis to be applied to proteomic assays, which has a number of advantages in throughput, sensitivity, and sample multiplexing.

AbstractBismuth‐based hybrid perovskites are candidates for lead‐free and air‐stable photovoltaics, but poor surface morphologies and a high band‐gap energy have previously limited these hybrid perovskites. A new materials processing strategy to produce enhanced bismuth‐based thin‐film photovoltaic absorbers by incorporation of monovalent silver cations into iodobismuthates is presented. Solution‐processed AgBi2I7 thin films are prepared by spin‐coating silver and bismuth precursors dissolved in n‐butylamine and annealing under an N2 atmosphere. X‐ray diffraction analysis reveals the pure cubic structure (Fd3m) with lattice parameters of a=b=c=12.223 Å. The resultant AgBi2I7 thin films exhibit dense and pinhole‐free surface morphologies with grains ranging in size from 200–800 nm and a low band gap of 1.87 eV suitable for photovoltaic applications. Initial studies produce solar power conversion efficiencies of 1.22 % and excellent stability over at least 10 days under ambient conditions.

Published: June 2016

ABSTRACTOrganosolv process is among the top choices for pretreatment of lignocellulosic biomass in cellulosic ethanol production. The lignin obtained as coproduct of this process is a low molecular weight biopolymer. Development of high‐value application for this material enhances the economic viability of the bioethanol production process. In this study, aqueous sodium hydroxide solution of organosolv lignin/poly(ethylene oxide) (PEO) blend with 95/5 wt % ratio was electrospun. The fiber morphology and thermal properties were compared with organosolv lignin/PEO fibers electrospun from N,N‐dimethylformamide (DMF) solution. Although organosolv lignin powder and fibers spun from DMF had a low Tg (∼100 °C), the fibers from alkaline aqueous solutions did not exhibit a glass transition point and could be carbonized without thermostabilization. The effects of carbonization heating rate, temperature, and time on the average fiber diameter, Raman peaks, and X‐ray diffraction results of the carbonized electrospun fibers were statistically analyzed by using a two‐level factorial design of experiments. Carbonization temperature, time, and interaction of these two parameters have the most significant effects. Formation of graphitized structures in the carbonized fibers was confirmed by transmission electron microscopy (TEM). The alkaline aqueous electrospinning of organosolv lignin has the advantages of using a green solvent, ability to increase the lignin content of fibers to more than 95 wt %, and removing the time and energy intensive step of thermostabilization before carbonization. © 2016 The Authors.

Synthesis and ferroelectric investigations of poly(vinylidene fluoride‐co‐hexafluoropropylene)‐Mg(NO3)2 films
Authors: Divya S. , Shakthi T. , Hemalatha J. 
Published: June 2016

ABSTRACTThe free‐standing, flexible, and ferroelectric films of poly(vinylidenefluoride‐co‐hexafluoropropylene) [P(VDF‐HFP)] were prepared by spin coating method. The ferroelectric phase of the films was enhanced by adding magnesium nitrate Mg(NO3)2 in different wt % as the additive during the film fabrication. The effects on the structural, compositional, morphological, ferroelectric, dielectric, and leakage current behaviors of the films due to the addition of salt were analyzed. Based on the X‐ray diffraction (XRD) patterns and Fourier Transform Infrared (FTIR) spectra, it is confirmed that the addition of Mg(NO3)2 promotes the electroactive β phase that induces the ferroelectric property. The fiber‐like topography of the films exhibits a nodule‐like structure, and the roughness of the films increases by the addition of Mg(NO3)2. The ferroelectric studies show the higher polarization values for the composite films than that of the plain P(VDF‐HFP) film. The Piezo‐response force microscope images also confirm the domain switching behavior of the samples. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44008.

AbstractA new family of small plant peptides was recently described and found to be widespread throughout the Millereae and Heliantheae tribes of the sunflower family Asteraceae. These peptides originate from the post‐translational processing of unusual seed‐storage albumin genes, and have been termed PawS‐derived peptides (PDPs). The prototypic family member is a 14‐residue cyclic peptide with potent trypsin inhibitory activity named SunFlower Trypsin Inhibitor (SFTI‐1). In this study we present the features of three new PDPs discovered in the seeds of the sunflower species Zinnia haageana by a combination of de novo transcriptomics and liquid chromatography‐mass spectrometry. Two‐dimensional solution NMR spectroscopy was used to elucidate their structural characteristics. All three Z. haageana peptides have well‐defined folds with a head‐to‐tail cyclized peptide backbone and a single disulfide bond. Although two possess an anti‐parallel β‐sheet structure, like SFTI‐1, the Z. haageana peptide PDP‐21 has a more irregular backbone structure. Despite structural similarities with SFTI‐1, PDP‐20 was not able to inhibit trypsin, thus the functional roles of these peptides is yet to be discovered. Defining the structural features of the small cyclic peptides found in the sunflower family will be useful for guiding the exploitation of these peptides as scaffolds for grafting and protein engineering applications.
Fusion and fission of molecular assemblies of amphiphilic polypeptides generating small vesicles from nanotubes
Authors: Watabe Naoki , Joo Kim Cheol , Kimura Shunsaku 
Published: June 2016

AbstractThree amphiphilic block polypeptides, (sarcosine)m‐b‐(l‐ or d‐Leu‐Aib)n (L16, D16, D14), having different helical chain lengths or helicity are synthesized. A mixture of L16, D16, and D14 generates vesicles of diameters more than ca. 130 nm by injecting the ethanol solution into water and heating at 90°C for 1 h. On the other hand, when nanotubes composed of L16 and D14 having ca. 50 nm diameter are mixed with nanosheets composed of D16, smaller and homogeneous vesicles of ca. 60 nm diameter are obtained with the heat treatment. The time lapse TEM image analysis of the mixtures revealed some transient structures of nanotubes sticking a nanosheet or a vesicle at the open end of nanotubes. The precise size control of vesicles is therefore attainable by using nanotubes as a structural template regulating the size of vesicles near to the nanotube diameter upon the membrane fission processes.

AbstractBackgroundPrevious research has shown that the human brain can be represented as a complex functional network that is characterized by specific topological properties, such as clustering coefficient, characteristic path length, and global/local efficiency. Patients with psychotic disorder may have alterations in these properties with respect to controls, indicating altered efficiency of network organization. This study examined graph theoretical changes in relation to differential genetic risk for the disorder and aimed to identify clinical correlates.MethodsAnatomical and resting‐state MRI brain scans were obtained from 73 patients with psychotic disorder, 83 unaffected siblings, and 72 controls. Topological measures (i.e., clustering coefficient, characteristic path length, and small‐worldness) were used as dependent variables in a multilevel random regression analysis to investigate group differences. In addition, associations with (subclinical) psychotic/cognitive symptoms were examined.ResultsPatients had a significantly lower clustering coefficient compared to siblings and controls, with no difference between the latter groups. No group differences were observed for characteristic path length and small‐worldness. None of the topological properties were associated with (sub)clinical psychotic and cognitive symptoms.ConclusionsThe reduced ability for specialized processing (reflected by a lower clustering coefficient) within highly interconnected brain regions observed in the patient group may indicate state‐related network alterations. There was no evidence for an intermediate phenotype and no evidence for psychopathology‐related alterations.
