Emerg. Infect. Dis

The multidrug-resistant (MDR) Salmonella enterica serotype Newport strain that produces CMY-2 β-lactamase(Newport MDR-AmpC) was the source of sporadic cases and outbreaks in humans in France during 2000–2005. Because this strain was not detected in food animals, it was most likely introduced into France through imported food products

Retos y nuevas perspectivas en la revegetación de sistemas forestales

Entre los días 21 y 23 de noviembre de 2007 tuvo lugar la I Reunión del Grupo de Trabajo de Repoblaciones Forestales de la Sociedad Española de Ciencias Forestales (SECF) y el grupo de trabajo de Restauración Ecológica de la Asociación Española de Ecología Terrestre, y IV Reunión del Grupo de Trabajo de Repoblaciones Forestales de la SECF en las instalaciones del Rectorado de la Universidad de Alcalá. A la reunión asistieron 74 participantes, y se presentaron un total de 39 comunicaciones orales, 18 paneles y 8 ponencias invitadas. Además, se presentó el libro “Calidad de Planta Forestal para la Restauración en Ambientes Mediterráneos” y se organizaron dos mesas redondas, una sobre “Necesidades reales de investigación en calidad de planta y cultivo de planta forestal en vivero” (Tabla 1) y otra sobre “Necesidades reales de la investigación en reforestación” (Tabla 2, 3). Una densa agenda para alcanzar los principales objetivos de la reunión, la presentación de investigación de calidad en el ámbito de la revegetación de sistemas forestales, y el intercambio de experiencias e inquietudes entre los diversos colectivos implicados en la misma. Pero ¿qué imagen podemos extraer del estado actual de nuestros conocimientos en esta área a partir de las comunicaciones presentadas

Modelling Pinus pinea forest management to attain natural regeneration under present and future climatic scenarios

Natural regeneration-based silviculture has been increasingly regarded as a reliable option in sustainable forest management. However, successful natural regeneration is not always easy to achieve. Recently, new concerns have arisen because of changing future climate. To date, regeneration models have proved helpful in decision-making concerning natural regeneration. The implementation of such models into optimization routines is a promising approach in providing forest managers with accurate tools for forest planning. In the present study, we present a stochastic multistage regeneration model for Pinus pinea L. managed woodlands in Central Spain, where regeneration has been historically unsuccessful. The model is able to quantify recruitment under different silviculture alternatives and varying climatic scenarios, with further application to optimize management scheduling. The regeneration process in the species showed high between-year variation, with all subprocesses (seed production, dispersal, germination, predation, and seedling survival) having the potential to become bottlenecks. However, model simulations demonstrate that current intensive management is responsible for regeneration failure in the long term. Specifically, stand densities at rotation age are too low to guarantee adequate dispersal, the optimal density of seed-producing trees being around 150 stems·ha−1. In addition, rotation length needs to be extended up to 120 years to benefit from the higher seed production of older trees. Stochastic optimization confirms these results. Regeneration does not appear to worsen under climate change conditions; the species exhibiting resilience worthy of broader consideration in Mediterranean silviculture

Dynamic Key-Value Memory Networks for Knowledge Tracing

Knowledge Tracing (KT) is a task of tracing evolving knowledge state of students with respect to one or more concepts as they engage in a sequence of learning activities. One important purpose of KT is to personalize the practice sequence to help students learn knowledge concepts efficiently. However, existing methods such as Bayesian Knowledge Tracing and Deep Knowledge Tracing either model knowledge state for each predefined concept separately or fail to pinpoint exactly which concepts a student is good at or unfamiliar with. To solve these problems, this work introduces a new model called Dynamic Key-Value Memory Networks (DKVMN) that can exploit the relationships between underlying concepts and directly output a student's mastery level of each concept. Unlike standard memory-augmented neural networks that facilitate a single memory matrix or two static memory matrices, our model has one static matrix called key, which stores the knowledge concepts and the other dynamic matrix called value, which stores and updates the mastery levels of corresponding concepts. Experiments show that our model consistently outperforms the state-of-the-art model in a range of KT datasets. Moreover, the DKVMN model can automatically discover underlying concepts of exercises typically performed by human annotations and depict the changing knowledge state of a student.Comment: To appear in 26th International Conference on World Wide Web (WWW), 201

Material y métodos: Estudio descriptivo observacional realizado en el primer semestre del curso 2014/2015 en el Campus Docent Sant Joan de Déu. Se hizo un análisis cualitativo de la conducción de 30 debriefings donde se evaluaron los resultados de aprendizaje en relación a los siguientes ítems (aspectos emocionales, toma de decisiones, valoración integral del paciente, valoración del paciente en atención domiciliaria, comunicación, educación sanitaria y habilidades técnicas). La satisfacción de los estudiantes se evaluó mediante un cuestionario compuesto por 8 ítems valorados mediante una escala ordinal (contenidos, coordinación, tiempo, metodología, utilidad, material, conocimientos, expectativas) y se realizó un análisis descriptivo de cada uno de ellos. Resultados: El análisis de los debriefings mostró que los alumnos tienen dificultades para realizar la valoración del paciente con los instrumentos que se utilizan en la práctica clínica, sin embargo presentan buenas habilidades comunicativas con el usuario y la familia. Respecto el grado de satisfacción, participaron en la cumplimentación del cuestionario, 47 estudiantes de tercer curso de Grado, la puntuación media total de los alumnos fue de 9,08 (DE 0,85). La utilidad del taller fue valorada con una media superior a 9. Conclusiones: La simulación clínica es una metodología docente valorada satisfactoriamente por parte de los alumnos, que permite trabajar objetivos relacionados con habilidades técnicas y con habilidades no técnicas

Micromammalian faunas from the middle miocene (middle Aragonian) of the Tudela formation (Ebro Basin, Spain)

Two new fossil micromammal localities of Middle Miocene age (Pico del Fraile 2, PF2 and Sancho Abarca 5, SA5) from the Tudela Formation (northeastern Ebro Basin) are described. PF2 contains rodents and insectivores of Aragonian age (local zone Dc). The rodent assemblage from the locality SA5 is very scarce and probably of Middle Aragonian age, like PF2. The micromammal fauna from the locality PF2 is very similar to that from Valdemoros 3B (VA3B) (Calatayud-Daroca Basin), including Microdyromys cf. remmerti, a species until now only described from the Miocene of the Daroca-Villafeliche area. Among the fauna recorded in PF2, a form of Democricetodon is described. The sedimentary record of the Pico del Fraile and Sancho Abarca sections and the mammalian findings extend the stratigraphic and paleontological knowledge of this part of the Ebro Basin, and allow its study in a continuous stratigraphic context
