    Examined the structure and correlates of a measure of prosocial moral reasoning in a sample of young and middle-aged adolescents. 1556 students (53% male, M age = 13.12, SD = .87) from Valencia, Spain completed paper-and-pencil measures of prosocial moral reasoning (PROM), empathy, prosocial behaviors, and aggression. As expected, a series of confirmatory factor and structural equation modeling analyses revealed a four-factor solution of the PROM to have the best fit (as compared to alternative models) among Spanish youth (across gender and grade). Moreover, higher level and other-oriented forms of prosocial moral reasoning were generally positively related to empathy and prosocial behaviors, and negatively related to aggression. In contrast, generally, lower level and self-focused modes of prosocial moral reasoning were negatively related to such prosocial tendencies, and positively related to aggression. Discussion focused on the psychometric properties of the PROM and its relations to theoretically-relevant correlates among Spanish yout

    Los resultados obtenidos en investigaciones acerca de la formación docente señalan que los conocimientos y competencias alcanzados por los egresados no responden adecuadamente a los desafíos de la compleja práctica profesional. Los diseños curriculares, no parecen tener en cuenta las condiciones desfavorables que caracterizan a la mayor parte de la realidad educativa. El Censo Nacional Docente del año 2004 señala que existen 55,576 docentes que trabajan en zonas rurales. Las investigaciones demuestran una ausencia generalizada de contenidos para el desempeño en instituciones insertas en contextos rurales o escuelas que atienden plurigrados. Quienes desempeñan esta tarea lo hacen desde las competencias y conocimientos adquiridos en procesos no especializados. La complejidad de estas situaciones requiere repensar alternativas para adecuar la formación docente a las necesidades de estas escuelas y docentes. Esta investigación estudia la adecuación de la formación docente inicial a las necesidades que demandan las escuelas y la comunidad en el ejercicio profesional en contextos de ruralidad. La investigación se lleva a cabo aplicando un enfoque cuantitativo y cualitativo, a partir del procesamiento , análisis e interpretación de la información que brinda una Planilla de Análisis de Tareas aplicada a docentes de escuelas rurales de la Provincia de Córdoba, y del estudio de las expectativas de la comunidad, de directivos y supervisores respecto a la capacitación profesional de los docentes. Este estudio espera contribuir con información que posibilite la mejora de los diseños curriculares para la oferta de Cursos de Postítulo para docentes que se desempeñan en escuelas primarias en contextos de ruralidad

    Comportamiento de patrones de tomate frente a la patogenicidad de Fusarium oxysporum f. sp. radicis-lycopersici

    La fusariosis del cuello y de las raíces del tomate ("mancha chocolate"), causada por el hongo F. o. f. sp. radicis-lycopersici, es una micosis cada vez más extendida en los cultivos de tomate de las provincias de Almería y Granada. Su gravedad es alta, llegando a alcanzar al 78% de las plantas en algún invernadero con cultivo sobre fibra de coco. Ante esta situación, se estimó necesario evaluar la resistencia de patrones utilizados para injertar variedades de tomate. Así, 16 patrones fueron valorados frente a una cepa muy patógena del hongo. Los patrones fueron:CLXTPG01, AR9704, AR97015, AR97009, Morgan, Spirit, Herman, Armstrong, Arnold, Big Power, Emperador, 61-071, Montezuma, Beaufort, Multifort, Maxifort, Tovi Star y Alegro. Dos ensayos sobre plantas en estado de 6-8 hojas verdaderas bien formadas, mostraron que todos los patrones expresaron una resistencia completa, exceptuando los denominados CLXTPG01 y AR97015. Entendemos que esta información es necesaria debidio a la escasa disponibilidad

    The IFMIF-DONES Project: Design Status and Main Achievements Within the EUROfusion FP8 Work Programme

    Get PDF
    International Fusion Materials Irradiation Facility-DEMO-Oriented NEutron Source (IFMIF-DONES) is a high-intensity neutron irradiation facility for qualification of fusion reactor materials, which is being designed as part of the European roadmap to fusion-generated electricity. Its main purpose is to study the behavior of materials properties under irradiation in a neutron flux able to simulate the same effects in terms of relevant nuclear responses as those expected in the first wall of the DEMO reactor which is envisaged to follow ITER. It is thus a key facility to support the design, licensing and safe operation of DEMO as well as of the fusion power plants that will be developed afterwards. The start of its construction is foreseen in the next few years. In this contribution, an overview of the IFMIF-DONES neutron source is presented together with a snapshot of the current engineering design status and of the relevant key results achieved within the EUROfusion Work Package Early Neutron Source (WPENS) as part of the 2014–2020 EURATOM Research and Training Programme, complementary to the EU Horizon 2020 Framework Programme (FP8). Moreover, some information on the future developments of the project are given

    Nut production in Bertholletia excelsa across a logged forest mosaic: implications for multiple forest use

    Get PDF
    Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction. Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world’s most economically-important NTFP species extracted almost entirely from natural forests across the Amazon Basin. An obligate out-crosser, Brazil nut flowers are pollinated by large-bodied bees, a process resulting in a hard round fruit that takes up to 14 months to mature. As many smallholders turn to the financial security provided by timber, Brazil nut fruits are increasingly being harvested in logged forests. We tested the influence of tree and stand-level covariates (distance to nearest cut stump and local logging intensity) on total nut production at the individual tree level in five recently logged Brazil nut concessions covering about 4000 ha of forest in Madre de Dios, Peru. Our field team accompanied Brazil nut harvesters during the traditional harvest period (January-April 2012 and January-April 2013) in order to collect data on fruit production. Three hundred and ninety-nine (approximately 80%) of the 499 trees included in this study were at least 100 m from the nearest cut stump, suggesting that concessionaires avoid logging near adult Brazil nut trees. Yet even for those trees on the edge of logging gaps, distance to nearest cut stump and local logging intensity did not have a statistically significant influence on Brazil nut production at the applied logging intensities (typically 1–2 timber trees removed per ha). In one concession where at least 4 trees ha-1 were removed, however, the logging intensity covariate resulted in a marginally significant (0.09) P value, highlighting a potential risk for a drop in nut production at higher intensities. While we do not suggest that logging activities should be completely avoided in Brazil nut rich forests, when a buffer zone cannot be observed, low logging intensities should be implemented. The sustainability of this integrated management system will ultimately depend on a complex series of socioeconomic and ecological interactions. Yet we submit that our study provides an important initial step in understanding the compatibility of timber harvesting with a high value NTFP, potentially allowing for diversification of forest use strategies in Amazonian Perù

    Evidence for divergent patterns of local selection driving venom variation in Mojave Rattlesnakes (\u3ci\u3eCrotalus scutulatus\u3c/i\u3e)

    Snake venoms represent an enriched system for investigating the evolutionary processes that lead to complex and dynamic trophic adaptations. It has long been hypothesized that natural selection may drive geographic variation in venom composition, yet previous studies have lacked the population genetic context to examine these patterns. We leverage range-wide sampling of Mojave Rattlesnakes (Crotalus scutulatus) and use a combination of venom, morphological, phylogenetic, population genetic, and environmental data to characterize the striking dichotomy of neurotoxic (Type A) and hemorrhagic (Type B) venoms throughout the range of this species. We find that three of the four previously identified major lineages within C. scutulatus possess a combination of Type A, Type B, and a ‘mixed’ Type A + B venom phenotypes, and that fixation of the two main venom phenotypes occurs on a more fine geographic scale than previously appreciated. We also find that Type A + B individuals occur in regions of inferred introgression, and that this mixed phenotype is comparatively rare. Our results support strong directional local selection leading to fixation of alternative venom phenotypes on a fine geographic scale, and are inconsistent with balancing selection to maintain both phenotypes within a single population. Our comparisons to biotic and abiotic factors further indicate that venom phenotype correlates with fang morphology and climatic variables. We hypothesize that links to fang morphology may be indicative of co-evolution of venom and other trophic adaptations, and that climatic variables may be linked to prey distributions and/or physiology, which in turn impose selection pressures on snake venoms

    Study of Spin and Decay-Plane Correlations of W Bosons in the e+e- -> W+W- Process at LEP

    Get PDF
    Data collected at LEP at centre-of-mass energies \sqrt(s) = 189 - 209 GeV are used to study correlations of the spin of W bosons using e+e- -> W+W- -> lnqq~ events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e+e- -> W+W- -> lnqq~ and e+e- -> W+W- -> qq~qq~ events. Decay-plane correlations, consistent with zero and with the Standard Model predictions, are measured

    Ultrarelativistic sources in nonlinear electrodynamics

    Get PDF
    The fields of rapidly moving sources are studied within nonlinear electrodynamics by boosting the fields of sources at rest. As a consequence of the ultrarelativistic limit the delta-like electromagnetic shock waves are found. The character of the field within the shock depends on the theory of nonlinear electrodynamics considered. In particular, we obtain the field of an ultrarelativistic charge in the Born-Infeld theory.Comment: 10 pages, 3 figure
