Parents’ Willingness and Perception of Children’s Autonomy as Predictors of Greater Independent Mobility to School
2019
The present study aimed to examine the factors associated with different forms of independent mobility (IM) to school (IM one way and IM both ways) according to their parents&rsquo

Factores que afectan al análisis biológico de las muestras de agresiones sexuales
2007
El concepto multidisciplinar de Ciencias Forenses se ha consolidado en los últimos años integrando un amplio espectro de profesionales de distintas disciplinas que ha abierto nuevas áreas de trabajo, en la mayoría de las cuales la interpretación del resultado se basa en la comparación con un material de referencia. Este trabajo pretende exponer brevemente una revisión de la casuística de Delitos Contra la Libertad Sexual (DCLS) estudiados en los laboratorios de Biología Forense y evaluar el rendimiento de la prueba de ADN a lo largo de los años en dos aspectos: uno en las situaciones inherentes a la metodología y otro en lo que respecta al cotejo de los vestigios analizados con las muestras…
La «Bataille de Caresme et de Charnage». Parodia e ironizzazione letteraria
2012
La «Bataille de Caresme et de Charnage» («Battaglia di Quaresima e Carnevale») è un poemetto francese di 574 ottosillabi a rima baciata, risalente al XIII sec., breve e lineare per ciò che riguarda l’articolazione narrativa, ma quanto mai complesso nelle sue interne e sotterranee significazioni. Un testo, la «Bataille», che si rivela campione privilegiato di indagine sia letteraria sia folklorico-antropologica, poiché caratterizzato da una sapiente tessitura di motivi che rimandano al "fabliau", al "lai", al "débat", al contrasto e, in ultima analisi, anche al teatro. Un testo, inoltre, evidentemente contrassegnato dalla costante e consapevole parodia dei temi e degli stilemi delle "chanson…
La investigación sobre manuales escolares de Geografía españoles: Análisis bibliométrico (1980-2019)
2020
espanolEl objetivo de esta investigacion es llevar a cabo un analisis bibliometrico sobre los trabajos que analizan los libros de texto de Geografia espanoles (1980-2019) atendiendo a: 1) Tendencia de los trabajos publicados; 2) Grado de internacionalizacion; 3) Tipo de contribucion; y 4) Principales tematicas de estudio y etapas educativas. Los principales resultados indican que la tendencia de los trabajos publicados ha experimentado un interes notable en la ultima decada, especialmente los relacionados con el Paisaje y Climatologia. En cuanto al tipo de contribucion, los articulos son los principales (51%) y, respecto al grado de internacionalizacion, los resultados ponen de manifiesto u…
Approches bioinformatiques innovantes pour l’analyse de données de séquençage à haut-débit appliquées à l’étude de pathologies génétiques rares avec …
2020
In the last years, the advent of exome sequencing (ES) in diagnosis and in research led to the identification of the genetic bases of many Mendelian disorders, allowing many diagnostic wavering cases to be solved. Nevertheless, ES data analysis only leads to the identification of pathogenic or likely pathogenic variants in 30 to 45 % of the undiagnosed cases. Indeed, some limits exist, both at clinical, molecular and bioinformatic levels. The constant evolution of the clinical knowledge, of the number of genes involved in human diseases, and of the clinical-biological correlations, has a significant impact on data analysis, leading to a progressive improvement in diagnostic research. Limits…
Top predators, mesopredators and their prey: interference ecosystems along bioclimatic productivity gradients
2010
1. The Mesopredator Release Hypothesis (MRH) suggests that top predator suppression of mesopredators is a key ecosystem function with cascading impacts on herbivore prey, but it remains to be shown that this top-down cascade impacts the large-scale structure of ecosystems. 2. The Exploitation Ecosystems Hypothesis (EEH) predicts that regional ecosystem structures are determined by top-down exploitation and bottom-up productivity. In contrast to MRH, EEH assumes that interference among predators has a negligible impact on the structure of ecosystems with three trophic levels. 3. We use the recolonization of a top predator in a three-level boreal ecosystem as a natural experiment to test if l…
Enchytraeid population dynamics: Resource limitation and size-dependent mortality
2009
Abstract Enchytraeids are regarded as keystone soil organisms in forest ecosystems. Their abundance and biomass fluctuate widely. Predicting the consequences of anthropogenic disturbances requires an understanding of the mechanisms underlying enchytraeid population dynamics. Here I develop a simple model, which predicts that the type of dynamics is controlled by resource input rate. If fungal resource input is a discrete event once a year, an exponential growth phase is followed by starvation and sharp decline of enchytraeid abundance. Model simulations with three different forcing functions were compared to field data. Initial parameter values were obtained from various independent sources…
Bicausative matrices to measure structural change: Are they a good tool?
1999
The causative-matrix method to analyze temporal change assumes that a matrix transforms one Markovian transition matrix into another by a left multiplication of the first matrix; the method is demand-driven when applied to input-output economics. An extension is presented without assuming the demand-driven or supply-driven hypothesis. Starting from two flow matrices X and Y, two diagonal matrices are searched, one premultiplying and the second postmultiplying X, to obtain a result the closer as possible to Y by least squares. The paper proves that the method is deceptive because the diagonal matrices are unidentified and the interpretation of results is unclear. Keywords : Input-Output ; Ch…
Bivariate nonlinear prediction to quantify the strength of complex dynamical interactions in short-term cardiovascular variability.
2005
A nonlinear prediction method for investigating the dynamic interdependence between short length time series is presented. The method is a generalization to bivariate prediction of the univariate approach based on nearest neighbor local linear approximation. Given the input and output series x and y, the relationship between a pattern of samples of x and a synchronous sample of y was approximated with a linear polynomial whose coefficients were estimated from an equation system including the nearest neighbor patterns in x and the corresponding samples in y. To avoid overfitting and waste of data, the training and testing stages of the prediction were designed through a specific out-of-sampl…
