Échelle auto-rapportée de psychopathie de Levenson : adaptation française et validation
L’échelle auto-rapportĂ©e de psychopathie de Levenson (LSRP ; Levenson, Kiehl & Fitzpatrick, 1995) est un instrument visant Ă Ă©valuer les traits de personnalitĂ© psychopathiques au sein de la population gĂ©nĂ©rale. Il conceptualise la psychopathie en deux facteurs distincts, mais interreliĂ©s, appelĂ©s psychopathie primaire et secondaire. La validitĂ© de l’instrument dans son format original est bien dĂ©montrĂ©e, mais aucune donnĂ©e n’est disponible en ce qui a trait Ă l’adaptation francophone de l’instrument. L’étude vise donc Ă Ă©valuer la structure factorielle et la validitĂ© convergente de la version française auprès d’une population de jeunes adultes. Un Ă©chantillon de 2529 participants âgĂ©s de 15 Ă Â 26 ans remplissent l’échelle auto-rapportĂ©e de psychopathie, le NEO-FFI et rĂ©pondent aussi Ă des questions sur leurs habitudes Ă l’égard de la consommation de substances psychoactives. Les rĂ©sultats des analyses factorielles exploratoires et confirmatoires montrent que l’adaptation francophone respecte la structure en deux facteurs, avec des coefficients de saturation et de consistance interne pour les deux Ă©chelles se comparant Ă ceux de la version originale anglaise. Les modèles de mesure pour les hommes et les femmes se sont avĂ©rĂ©s partiellement invariants ; les hommes obtiennent des rĂ©sultats supĂ©rieurs Ă ceux des femmes aux Ă©chelles de psychopathie primaire et totale. Enfin, le LSRP dĂ©montre de bons indices de validitĂ© convergente.The Levenson Self-Reported Psychopathy Scale (LSRP ; Levenson, Kiehl & Fitzpatrick, 1995) is designed to assess subclinical psychopathic personality traits in the general population. In this measure, psychopathy is conceptualized along two distinct but interrelated factors, referred to as primary and secondary psychopathy. Several studies support the psychometric properties of the original version ; however, none reported fidelity and convergent validity coefficients for the French adaptation of the LSRP. The current study aims to assess the factorial structure and convergent validity of the LSRP’s French adaptation in young adults. A sample of 2529 French-Canadian participants, aged between 15 and 26 years old, completed the LSRP, the NEO-FFI, and answered questions on psychoactive substance use. Exploratory and confirmatory factor analyses supported the two-factor structure of the instrument. In addition, internal consistency coefficients from the original version were replicated. Measurement models for women and men were partially invariant, but men scored significantly higher than women on primary psychopathy and on the total scale. Finally, the LSRP showed good convergent validity coefficients. The French adaptation of the Levenson Self-Reported Psychopathy Scale shows good psychometric properties and results are similar to those obtained in the original version.La escala auto-reportada de psicopatĂa de Levenson (LSRP ; Levenson, et al., 1995) es un instrumento que pretende evaluar los rasgos de personalidad psicopáticos en el seno de la poblaciĂłn general. Ésta conceptualiza la psicopatĂa en dos factores distintos, pero interrelacionados, llamados psicopatĂa primaria y secundaria. La validez del instrumento en su forma original está bien demostrada, pero ninguna informaciĂłn se encuentra disponible en lo que respecta a la adaptaciĂłn francĂłfona del instrumento. Por lo tanto, el estudio apunta a evaluar la estructura factorial y la validez convergente de la versiĂłn francesa en la poblaciĂłn de adultos jĂłvenes. Una muestra de 2.529 participantes con edades comprendidas entre 15 y 26 años completan la escala auto-reportada de psicopatĂa, la NEO-FFI, y responden tambiĂ©n a preguntas sobre las costumbres del consumo de sustancias psicoactivas. Los resultados de los análisis factoriales exploratorios y confirmatorios muestran que la adaptaciĂłn francĂłfona respeta la estructura en dos factores, con coeficientes de saturaciĂłn y de consistencia interna para las dos escalas comparables a aquĂ©llas de la versiĂłn original en inglĂ©s. Los modelos de medida para los hombres y las mujeres se han mostrado parcialmente invariables ; los hombres obtienen resultados superiores a los de las mujeres en las escalas de psicopatĂa primaria y total. Finalmente, le LSRP demuestra buenos Ăndices de validez convergente
La ruée vers l’or rose
Depuis une dizaine d'années, on parle de la crevette comme de l'« or rose de Madagascar ». Cette expression traduit bien l'importance de cette ressource pour l'économie d'un pays considéré comme l'un des plus pauvres de la planète et pour une frange grandissante de la population qui vit de la pêche et de la collecte. Tout comme d'autres activités « pionnières » telles que l'exploitation des pierres précieuses, la pêche crevettière appelle une mobilisation d'un nombre remarquable d'acteurs. Outre la véritable ruée observée vers les fronts pionniers de la pêche crevettière traditionnelle, les autres secteurs de cette activité (artisanal, industriel) connaissent également des dynamiques d'évolution rapide auxquelles participent de multiples intervenants. Cette situation engendre des interactions complexes entre différents types d'acteurs (politiques, bailleurs de fonds internationaux, ONG...) et à différentes échelles, du local à l'international. Cet ouvrage aborde ainsi l'étude de la pêche traditionnelle et de sa croissance selon diverses échelles et déterminants (économique, social, politique, écologique, religieux...) qui, loin de s'exclure mutuellement, se complètent pour tendre vers une meilleure compréhension des dynamiques et des transformations en cours dans ce secteur. Il est le fruit de la collaboration de chercheurs de diverses disciplines (anthropologues, économistes, sociologues) et origines (canadienne, française, malgache) qui à la croisée des regards, s'interrogent et dialoguent sur le rôle catalyseur de la pêche dans les dynamiques économiques et sociales que connaît actuellement Madagascar et, partant, sur l'exemplarité du cas malgache pour la compréhension globale des problématiques de la pêche au niveau international.Traditional shrimp fishing in Madagascar is a major political and socioeconomic issue in the country today, and also a scientific subject of great interest for the social sciences. This interest results from both its internal characteristics and its complex relations with the other components of prawn fishing and also from the conditions of its integration in the socioeconomic systems of the coastal regions. This book is the fruit of collaboration between numerous researchers in various disciplines (anthropologists, economists and sociologists) and of various origins (Canadian, French and Madagascan). It examines traditional fishing and its growth at different levels and according to various determinants (economic, political, ecological, religious, etc.) which, far from being mutually exclusive, complete each other for better comprehension of the dynamics and changes in progress. The research presented here calls into question the vision of archaic artisanal fishing doomed to disappear in time or be taken over by more modern forms of operation. The history of shrimp fishing over the past 30 years shows its strong capacity for change: institutional and social (the growing role played by associations, the adaptation of traditional powers), economic (growing opening to domestic and international markets) and technological (the use of new fishing techniques). It is also shown that the growth and development of this activity are not based solely on internal factors or on ecological or technical determinism. Traditional fishing is closely involved in the changes and adjustments experienced by the coastal communities and socioeconomic systems. Like other ’pioneer’ activities such as the mining of precious stones, it has a catalysing effect on certain major contemporary phenomena (migration and the development of a market economy), increasing its value as an example and broadening the relevance of the conclusions of the book
Disk-to-Disk network transfers at 100 Gb/s
A 100 Gbps network was established between the California Institute of Technology conference booth at the Super Computing 2011 conference in Seattle, Washington and the computing center at the University of Victoria in Canada. A circuit was established over the BCNET, CANARIE and Super Computing (SCInet) networks using dedicated equipment. The small set of servers at the endpoints used a combination of 10GE and 40GE technologies, and SSD drives for data storage. The configuration of the network and the server configuration are discussed. We will show that the system was able to achieve disk-to-disk transfer rates of 60 Gbps and memory-to-memory rates in excess of 180 Gbps across the WAN. We will discuss the transfer tools, disk configurations, and monitoring tools used in the demonstration
Efficient LHC Data Distribution across 100Gbps Networks
During Supercomputing 2012 (SC12), an international team of high energy physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech), the University of Victoria, and the University of Michigan, together with Brookhaven National Lab, Vanderbilt and other partners, smashed their previous records for data transfers using the latest generation of wide area network circuitsWith three 100 gigabit/sec (100 Gbps) wide area network circuits [1] set up by the SCinet, Internet2, CENIC, CANARIE and BCnet, Starlight and US LHCNet network teams, and servers at each of the sites with 40 gigabit Ethernet (40GE) interfaces, the team reached a record transfer rate of 339 Gbps between Caltech, the University of Victoria Computing Center in British Columbia, the University of Michigan, and the Salt Palace Convention Center in Utah. This nearly doubled last year's overall record, and eclipsed the record for a bidirectional transfer on a single link with a data flow of 187 Gbps between Victoria and Salt Lake
