The evolution of collective infectious units in viruses
2019
Viruses frequently spread among cells or hosts in groups, with multiple viral genomes inside the same infectious unit. These collective infectious units can consist of multiple viral genomes inside the same virion, or multiple virions inside a larger structure such as a vesicle. Collective infectious units deliver multiple viral genomes to the same cell simultaneously, which can have important implications for viral pathogenesis, antiviral resistance, and social evolution. However, little is known about why some viruses transmit in collective infectious units, whereas others do not. We used a simple evolutionary approach to model the potential costs and benefits of transmitting in a collect…
Valoración de la Ecología de Aprendizaje Autorregulado Virtualizada para la Didáctica de las Ciencias de la Naturaleza durante la crisis COVID-19
2021
Los modelos de enseñanza-aprendizaje universitarios están siendo afectados por la crisis originada por la COVID-19. Para atender a esta crisis desencadenada se diseñó de urgencia una propuesta de ecología de aprendizaje autorregulado virtualizada durante el confinamiento de 2020 en la asignatura de Ciencias de la Naturaleza y su Didáctica I del Grado en Maestro de Educación Primaria. En este artículo se describe esta ecología de aprendizaje: los materiales elaborados, los contextos diseñados y la utilización de estrategias de enseñanza-aprendizaje basadas en el aprendizaje autorregulado, tanto durante la docencia virtual como durante la tutorización del alumnado. El objetivo de este estudio…
Creativity in Middle Childhood: Influence of Perceived Maternal Sensitivity, Self-esteem, and Shyness
2016
This study aimed to examine the relationship between maternal sensitivity and affect, as perceived by the child, and childhood creativity. Self-esteem and shyness were considered mediating factors. A total of 151 elementary school pupils were tested on verbal and pictorial creativity, self-esteem, and perceived maternal affect and sensitivity. Their teachers assessed each child’s shyness in their relations at school. A Multiple Indicators and Multiple Causes (MIMIC) model of the causal relationships among the study’s variables was tested. Results supported this theoretical model of causality. Maternal sensitivity had a significant, direct, positive effect on self-esteem, and a direct negati…
A Probabilistic Classification Procedure Based on Response Time Analysis Towards a Quick Pre-Diagnosis of Student's Attention Deficit
2019
[EN] A classification methodology based on an experimental study is proposed towards a fast pre-diagnosis of attention deficit. Our sample consisted of school-aged children between 8 and 12 years from Valencia, Spain. The study was based on the response time (RT) to visual stimuli in computerized tasks. The process of answering consecutive questions usually follows an ex-Gaussian distribution of the RTs. Specifically, we seek to propose a simple automatic classification scheme of children based on the most recent evidence of the relationship between RTs and ADHD. Specifically, the prevalence percentage and reported evidence for RTs in relation to ADHD or to attention deficit symptoms were t…
Multivariate EEG spectral analysis evidences the functional link between motor and visual cortex during integrative sensorimotor tasks
2012
The identification of the networks connecting brain areas and the understanding of their role in executing complex tasks is a crucial issue in cognitive neuroscience. In this study, specific visuomotor tasks were devised to reveal the functional network underlying the cooperation process between visual and motor regions. Electroencephalography (EEG) data were recorded from twelve healthy subjects during a combined visuomotor task, which integrated precise grip motor commands with sensory visual feedback (VM). This condition was compared with control tasks involving pure motor action (M), pure visual perception (V) and visuomotor performance without feedback (V + M). Multivariate parametric …
La ‘svolta ontologica’ e le questioni epistemologiche in antropologia
2020
In the first part of this article I propose to approach the ‘ontological turn’ in anthropology by focusing on how Martin Holbraad and Eduardo Viveiros de Castro link epistemological, ontological and political issues. Focusing on their new epistemological views to others’ forms of thought and their intrinsic conceptual and ontological presuppositions, inexplicable through the recourse to external determinants, these scholars aim at a radical epistemological and political questioning of the bipartitions of Western modern ontology (such as nature vs culture) in line with Bruno Latour’s ideas on ‘modern constitution’ and its distinction between ‘matters of fact’ and ‘matters of concern’. The ar…

D’amore e d'arte. Le lettere a Eleonora Duse di Aleksandr Volkov nel lascito Thun-Salm e Thun-Hohenstein
2021
Aleksandr Volkov's letters to Eleonora Duse - almost completely neglected for more than ninety years - tell us Duse’s relationship with Volkov, i.e. between Lenor and Alex: a liaison that was fed on art and life, as well as on ordinary and extraordinary facts of history. The correspondence is composed of 303 letters, telegrams and notes written by Volkov to Duse in 1891 and 1892. We have not the letters that Lenor sent to Alex, but some fragments of them have been preserved, cited by Volkov in his letters. Moreover, some actress’s notes are still legible in the margin of some of Volkov’s letters and telegrams. If we combine them with the copious documentation on the actress which is extensi…
Plant Productivity Dispersion and the College Premium: Evidence from the United States 1977-1997
2015
For the United States in 1987-2014, I document at business cycle frequencies that the high-skill workers’ employer size wage premium is high (low) in times of low (high) unemployment relative to that of the low-skill workers. Specifically, the differential employer size wage premium between high-skill and low-skill workers has an unconditional correlation of -0.4 with the unemployment rate, and varies by about 6 percent over the business cycle. The skill premium itself does not exhibit a clear business cycle pattern over the sample period.
