Violencia de los jóvenes : La educación antes que el todo por la seguridad
Nos enfrentamos más a un desarrollo de las violencias de actitudes dirigidas hacia las instituciones y sus representantes que a un incremento de los actos delictivos graves. Estas micro-violencias identificadoras y reactivas perpetradas por los jóvenes de los barrios periféricos son la expresión de un sufrimiento y la señal de una llamada lanzada a los adultos. El trabajo educativo, indudablemente más complejo y menos espectacular que las respuestas represivas, permite conseguir unos mejores resultados en cuanto a la prevención de la violencia y corresponde mejor a las necesidades de protección de los niños y adolescentes.

Stakes of a youth housing policy
Intermittence and temporary situations, ambivalence of behaviours, cohabitation, training, labour and couples on the try : the young people’s demands in matter of housing are variable and flexible. Although the private rental market accomodates the majority of young people, it does not however allow all of them to have access to independence and then to autonomy. How to think about a youth housing policy in the plurality of situations ?
La jeunesse chilienne et le droit à la sexualité
Authors: Vidal Pollarolo Paulina 
Published: May 2013

Young people’s rights to sexuality and procreation in Chile.
In spite of the ratification by the Chile of the international agreements during the conferences of the United Nations about the young people’s sexual and procreative rights, governments have not defended these rights and no policy has been implemented to enable young people to know and exercise them. This attitude is mainly due to the influence of the hierarchy of the Catholic church that imposes a conservative discourse on the themes of the family and sexuality. This discourse does not correspond to the young people’s behaviours who have a more active and precocious sexuality. This paper tackles the question of respect of these rights in view of social equity and emphasizes the need to develop adapted programmes of sexual education.
Construction des catégories sportives juvéniles

Aufbau der Sportkategorien der Jugendlichen

Der Kreis der Erzieher scheint heute den Glaube an die positiven Wirkungen des Sports in seinen vielfältigsten Arten zu teilen und zwar vom institutionalisierten Sport (in Vereine), der das Erlernen der Lebensregeln fördern würde bis zu den "freien" oder
"selbstorganisierten" Sportarten, die den Ausdruck der Schaffung der Jugendlichen und die sportliche Postmoderne ermöglichen. Eine neue sportliche Wirklichkeit zeichnet sich allmählich ab und tendiert dazu, zwei Sportwelten der Jugendlichen gegenüber zu stellen und zwar die der begleiteten Sportler, die in der sportlichen Tradition verankert sind, und die der unorganisierten Jugendlichen, die eher zur sportlichen Modernität tendieren. Wie in anderen Bereichen der kulturellen Praxis der Jugendlichen scheint die Forschung im Bereich der Soziologie und des Marketings des Sports am Aufbau dieser Kategorien und dieser •sozialen Zauberkunst“ teilgenommen zu haben.

De la democracia en las asociaciones culturales

El ministerio de la Cultura publicó en 2001 un dossier para celebrar la ley de 1901 sobre las asociaciones sin ánimo de lucro. Mostraba la importancia y la fragilidad de las asociaciones en la cultura y las artes. Presentar esta publicación hoy, es mostrar que estas dificultades persisten. La realidad es más áspera que los discursos generosos : los recortes presupuestarios amenazan las 157 000 (de 880 000) asociaciones concernidas. Las asociaciones «postizas» creadas por el ministerio por razones contables son el árbol que esconde un bosque devastado cuyo vigor interno se conoce, pero cuyas sendas y cuyo perímetro se desconocen. Esta síntesis presenta unos artículos inspirados por el derecho, la economía, la estadística y la política, que se acercan al enfoque más histórico publicado aquí por

Support for youth employment in EU
Based on a study carried out within the framework of the Leonardo European programme in eight countries, the authors bring out a number of points of convergence : transition from a prospect oriented towards employment to an axis focusing on integration and education and the development of logics in terms of employability ; weak consideration of the logic of offers contrary to what is asserted, permanency of strong inequalities according to gender. Beyond the convergences, many divergences appear in relation with the different approaches concerning the concepts of integration and citizenship. From these convergences and divergences, five main models can be distinguished.
La politique de jeunesse au Royaume-Uni : une évaluation critique

Youth policies in UK : a critical evaluation
This paper examines the place of youth work in a context of political developments in England and the four foundations of the current approach of youth policies : results, integrated services ; multidisciplinary teams and youth participation. In addition, it analyses the broad range of policies implemented by the British Government since 1997 to increase participation in education and training. Finally, it focuses on the transition to adult age for the post adolescents who often slip through the net of services centered, on the one hand, on teenagers and, on the other hand, on adults. The paper also examines the British commitment in Europe.

Marginalité et musiques électroniques
Authors: Petiau Anne 
Published: May 2013

Comme d’autres courants musicaux populaires de la seconde moitié du
XXe siècle, les musiques électroniques ont donné lieu à une sous-culture juvénile. À partir de l’expérience des musiciens électroniques, pour qui le développement d’une pratique musicale va de pair avec des expériences collectives et se fait dans un contexte de vie qui peut aller jusqu’à l’expérimentation d’un mode de vie marginal, l’article propose de réfléchir à la singularisation de la jeunesse comme âge de la vie et aux modèles culturels qui informent ces expériences, et par là de porter un autre regard sur les sous-cultures de la jeunesse.

Published: May 2013

Background Achievement of early viral suppression is important in patients with chronic HCV infection treated with telaprevir (TLV) or boceprevir (BOC) to avoid selection of drug resistance and attain cure. No head-to-head studies comparing TLV and BOC have been performed so far. Methods All consecutive individuals who initiated triple HCV therapy with TLV or BOC outside clinical trials at three European clinics were evaluated. Rapid virological response (RVR) was defined as unquantifiable HCV RNA (<25 IU/ml) at week 4 for TLV and at week 8 for BOC (4 weeks after lead-in). Results A total of 106 patients were evaluated, 33 treated with BOC and 73 with TLV. Median age, gender, body mass index, baseline HCV RNA, HCV subtype 1a (45% versus 42%) and IL28B-CC alleles (29% versus 23%) did not differ significantly in BOC and TLV groups, respectively. HIV coinfection was more prevalent in patients on TLV than BOC (24% versus 44%). Conversely, more patients on BOC than TLV had previously failed pegylated interferon plus ribavirin (82% versus 64%). RVR was achieved by 82% of patients on TLV versus 59% on BOC ( P=0.001). Multivariate logistic regression analysis confirmed that TLV use was the strongest predictor of RVR (OR 3.54 [95% CI 1.23, 10.24]; P=0.02), others being HCV subtype 1b versus 1a (OR 3.26 [95% CI 1.17, 9.09]; P=0.02) and low baseline HCV RNA (OR 0.41 [95% CI 0.16, 1.03]; P=0.06). Prior interferon exposure, HIV coinfection or absence of advanced liver fibrosis did not influence the likelihood of RVR. Conclusions Compared to BOC, triple therapy with TLV produces greater RVR rates. TLV might be a better option in more difficult-to-cure patients, such as those with high baseline HCV RNA and/or HCV 1a subtype. HIV coinfection does not influence early HCV RNA responses.
La télévision selon Alfred Hitchcock. Une esthétique de l’émergence
Authors: Delavaud Gilles 
Published: May 2013

Alfred Hitchcock ne se contente pas d’apparaître au début et à la fin de chaque épisode de ses séries télévisées Alfred Hitchcock Presents (1955-1962) et The Alfred Hitchcock Hour (1962-1965). Il se met en scène, incarne un quasi-personnage (qui n’est ni Hitchcock producteur ni Hitchcock réalisateur), joue un rôle. Et en même temps, il tient un discours. Celui-ci n’a le plus souvent que peu de rapport avec la fiction qu’il est censé présenter. Hitchcock nous parle d’autre chose, principalement (et avec une constance remarquable) de télévision : de la télévision comme institution et comme dispositif. Pour lui, le dispositif télévisuel, comme celui du cinéma, est un dispositif ludique ; mais les règles du jeu diffèrent. En télévision, la présentation est essentielle. Dans cet article centré sur la notion de présentation, l’auteur se demande d’abord à quoi joue Hitchcock présentateur. Puis, en quels termes nouveaux se pose, pour le cinéaste, le délicat problème de la « direction de spectateurs » : qu’advient-il de cette ambition de contrôle, considérée par lui comme constitutive de son art, lorsqu’on n’a plus affaire, comme au cinéma, à un public captif ? Par l’établissement d’une définition de l’« esthétique de l’émergence », l’auteur propose des éléments de réponse permettant d’éclairer la stratégie hitchcockienne.
Du degré zéro au second degré dans la fiction télévisuelle québécoise
Authors: Picard Yves 
Published: May 2013

Constatant que la fiction télévisuelle aurait atteint depuis peu un « âge d’art », l’auteur remonte le fil de la théorie pour éclairer le trajet esthétique du domaine, du degré zéro au second degré. Le degré zéro de la fiction télévisuelle serait marqué par le retrait de la visualité au profit de l’attrait de l’oralité (Caldwell et Butler). Le second degré de la fiction télévisuelle serait pour sa part caractérisé par l’attrait de la visualité, souvent accompagné d’un retrait de l’oralité (Genette et Metz). L’auteur soutient ces propositions en examinant deux objets de la fiction télévisuelle québécoise, liés par un thème commun, celui du retour d’un homme réticent à parler de son passé :Le Survenant(1954-1960) etAveux(2009).
Neural adaptive control for leader–follower flocking of networked nonholonomic agents with unknown nonlinear dynamics
Authors: Peng Zhouhua , Wang Dan , Liu Hugh H. T. , Sun Gang 
Published: May 2013

SUMMARYThis paper is concerned with the leader–follower flocking problem of networked nonholonomic multi‐agent systems with non‐identical unknown nonlinear dynamics. The leader motion to be synchronized is also nonlinear and unknown. By employing the graph theory and a pinning control technique, a distributed neural adaptive control design is developed for the agents to achieve motion synchronization with the leader. The design is for a directed communication graph with a fixed topology. A collective potential function is used to maintain cohesion between the agents. On the basis of Lyapunov analysis, the developed neural flocking algorithm guarantees that all the agents’ headings and speeds are synchronized with the leader and collisions between the agents can be avoided. An illustrative example is given to show the effectiveness of the proposed control strategy. Copyright © 2013 John Wiley & Sons, Ltd.
Natural Rubber–Toughened Nylon12 Compatibilized by Polystyrene/Natural Rubber Blend
Authors: Saengthaveep Saravalee , Magaraphan Rathanawan 
Published: May 2013

ABSTRACTNylon12 (polyamide12)/natural rubber (NR‐grade STR 5L)/ compatibilizer blends were prepared by melt blending in a twin‐screw extruder with various compatibilizer contents. The copolymer of polystyrene and natural rubber (PS/NR) was used as a compatibilizer. Then a scanning electron microscope was used to study the phase morphology and the mechanical and rheological properties. At the optimum compatibilizer content of 10 phr, the [Nylon12/NR]/[PS/NR] blends showed improved mechanical properties and fine phase morphology (good dispersion of NR in Nylon12 matrix). This is due to decreased domain size of the dispersed rubber phase, leading to decreased deformability of the rubber particle and increased compatibility of the blend. For the flow properties, increased interfacial interaction between NR domains and Nylon12 matrix can result in increased shear viscosity and decreased extrudate swell. © 2013 Wiley Periodicals, Inc.

A behavioral view on chimpanzee personality: Exploration tendency, persistence, boldness, and tool‐orientation measured with group experiments

Published: May 2013

AbstractHuman and nonhuman animals show personality: temporal and contextual consistency in behavior patterns that vary among individuals. In contrast to most other species, personality of chimpanzees, Pan troglodytes, has mainly been studied with non‐behavioral methods. We examined boldness, exploration tendency, persistence and tool‐orientation in 29 captive chimpanzees using repeated experiments conducted in an ecologically valid social setting. High temporal repeatability and contextual consistency in all these traits indicated they reflected personality. In addition, Principal Component Analysis revealed two independent syndromes, labeled exploration‐persistence and boldness. We found no sex or rank differences in the trait scores, but the scores declined with age. Nonetheless, there was considerable inter‐individual variation within age‐classes, suggesting that behavior was not merely determined by age but also by dispositional effects. In conclusion, our study complements earlier rating studies and adds new traits to the chimpanzee personality, thereby supporting the existence of multiple personality traits among chimpanzees. We stress the importance of ecologically valid behavioral research to assess multiple personality traits and their association, as it allows inclusion of ape studies in the comparison of personality structures across species studied behaviorally, and furthers our attempts to unravel the causes and consequences of animal personality.

Separation of lysozyme with magnetically stabilized spherical hydroxyapatite microcomposites in a continuous flow system
Authors: Akkaya Birnur 
Published: May 2013

ABSTRACTThe aim of this study was to produce a spherical and magnetic hydroxyapatite (HA) microcomposite to use as an adsorbent for the separation of lysozyme in a magnetically stabilized fluidized bed and to separate lysozyme from a protein mixture composed of human immunoglobulin G, human serum albumin, and lysozyme. For this purpose, spherical and magnetic HA microcomposites (50–100 μm) were synthesized by suspension polymerization and characterized by Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, electron spin resonance, vibrating‐sample magnetometry, Brunauer–Emmett–Teller analysis, and a swelling test. The specific surface areas of the pure HA and magnetic HA microcomposite were determined to be 72.25 and 151.53 m2/g, respectively. The swelling ratio of the spherical HA microcomposites was 150%. Adsorption experiments were conducted under conditions that differed in terms of pH, temperature, ionic strength, flow velocity, and magnetic field. According to the findings of the adsorption kinetic studies, the adsorption process was appropriate to pseudo‐first‐order kinetics. The separation of the lysozyme from the protein mixture was achieved by means of a 50 mM pH 7.0 phosphate buffer. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 1602–1610, 2013
Electrothermal lifetime prediction of polyimide wire insulation with application to aircraft
Authors: Hondred Peter R. , Bowler Nicola , Kessler Michael R. 
Published: May 2013

ABSTRACTThis work investigates the electrothermal lifetime of a commonly used polyimide wire insulation material, Kapton®, through the use of thermogravimetry (TG) and breakdown voltage testing. From TG, an isoconversional model‐free kinetic evaluation was used to obtain a relationship between the activation energies of degradation for Kapton as a function of weight loss. By relating the electrical life theory and the TG theory through the model defined by Toop (IEEE Trans. Dielectr. Electr. Insul. 1971, 6, 2), the electrothermal lifetime of Kapton has been calculated for conditions of 12 and 14.7 kV over a temperature range of 250–400°C. The resulting model can be used to make lifetime predictions for wire insulation degradation in aging aircraft for improved safety and risk assessment. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Published: May 2013

ABSTRACTA series of copolyimides were prepared by incorporating pyromellitic dianhydride (PMDA) into the homopolyimide derived from 5,4′‐diamino‐2‐phenyl benzimidazole (DAPBI) and 3,3′,4,4′‐biphenyl tetracarboxylic dianhydride (s‐BPDA), with the purpose of enhancing backbone rigidity of the homopolyimide. A systematic change in thermal, mechanical and optical properties was observed by changing the ratios of PMDA and s‐BPDA components. Glass transition temperatures were in the range of 404–425°C, depending on the pyromellitimide content. Mechanical properties were significantly enhanced: Tensile modulus and strength ranged from 5.8 to 8.5 GPa and 249 to 263 MPa, respectively, and much higher than that of the homopolyimide (s‐BPDA/DAPBI). Wide‐angle X‐ray diffractions showed that the copolymer films were amorphous, although locally ordered regions were observed with long periodicity larger than that of the homopolyimide. The properties enhancement was attributed to the increased overall rigidity of the polymer backbones and enhanced molecular in‐plane orientation. Possible structure–property relationships were also discussed. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 1653–1658, 2013
Influence of processing on morphology in short aramid fiber reinforced elastomer compounds

Published: May 2013

ABSTRACTThe rubber industry is nowadays facing the general increase of raw materials as the customers are confronted with rising prices for energy. Therefore there is a need for higher durability of elastomer applications. Short fiber reinforced elastomers can contribute to the improvement of dynamic and wear properties. To determine structure–property relationships in short fiber reinforced elastomer compounds it is of crucial interest to know the contributions of fiber aspect ratio, volume content, orientation and fiber–elastomer interaction. Therefore the influence of different processing conditions and fiber contents on the resulting morphology and macroscopic properties was investigated in this article by the help of fluorescence and confocal laser microscopy using a transparent ethylene‐propylene‐diene rubber (EPDM) matrix. It was found that the processing induced fiber breakage was the key factor in determining the composite morphology and subsequent physical properties. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Development of an LC/MS/MS method in order to determine arctigenin in rat plasma: its application to a pharmacokinetic study
Authors: Zou Quanfei , Gu Yuan , Lu Rong , Zhang Tiejun , Zhao Guang‐Rong , Liu Changxiao , Si Duanyun 
Published: May 2013

ABSTRACTIn this study, a simple and sensitive LC/MS/MS method was developed and validated for the determination of arctigenin in rat plasma. The MS detection was performed using multiple reaction monitoring at the transitions of m/z 373.2 → 137.3 for arctigenin and m/z 187.1 → 131.0 for psoralen (internal standard) with a Turbo IonSpray electrospray in positive mode. The calibration curves fitted a good linear relationship over the concentration range of 0.2–500 ng/mL. It was found that arctigenin is not stable enough at both room temperature and −80 °C unless mixed with methanol before storage. The validated LC/MS/MS method was successfully applied for the pharmacokinetic study of arctigenin in rats. After intravenous injection of 0.3 mg/kg arctigenin injection to rats, the maximum concentration, half‐life and area under the concentration–time curve were 323 ± 65.2 ng/mL, 0.830 ± 0.166 and 81.0 ± 22.1 h ng/mL, respectively.

Formation and Properties of Self‐Assembly‐Driven Fluorescent Nanoparticle Sensors
Authors: Cui Kun , Lu Xuemin , Guan Junfang , Lu Qinghua , Fei Zhaofu , Dyson Paul J. 
Published: May 2013

AbstractFluorescent nanoparticles (FNPs) are obtained in water by self‐assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interactions. The hydrophobicity of the surfactant is tunable and a highly hydrophobic surfactant increases the fluorescence intensity and stability of the FNPs. The fluorescence of the FNPs is sensitive to a quenching effect by various ions with high selectivity, and consequently, they may be used as sensors. The self‐assembly approach used to generate the FNPs is considerably simpler than other methods based on more challenging synthetic methods and the flexibility of the approach should allow a wide and diverse range of FNPs to be prepared with specific sensor applications.
