Models for highway traffic and their connections to thermodynamics
2007
Models for highway traffic are studied by numerical simulations. Of special interest is the spontaneous formation of traffic jams. In a thermodynamic system the traffic jam would correspond to the dense phase (liquid) and the free flowing traffic would correspond to the gas phase. Both phases depending on the density of cars can be present at the same time. A model for a single lane circular road has been studied. The model is called the optimal velocity model (OVM) and was developed by Bando, Sugiyama, et al. We propose here a reformulation of the OVM into a description in terms of potential energy functions forming a kind of Hamiltonian for the system. This will however not be a globally …
Pilot study on university students' opinion about STEM studies at higher education
2020
The percentages of women enrolled in higher education in the STEM sector are significantly lower than those of men. Overall, gender representation in science, technology, engineering and mathematics degrees in Europe is not balanced. The Leaky Pipeline phenomenon, marked by gender stereotypes, makes the latent gender gap a relevant topic of study. Studies exist on academic performance, self-perception, self-efficacy, outcome expectations; however, studying gender stereotypes linked to STEM studies is also essential. It is necessary to know the social and family context in which young people have grown up, as well as their perception of such studies. To study gender stereotypes of university…
A comprehensive evaluation of potential lung function associated genes in the SpiroMeta general population sample
2011
Lung function measures are heritable traits that predict population morbidity and mortality and are essential for the diagnosis of chronic obstructive pulmonary disease (COPD). Variations in many genes have been reported to affect these traits, but attempts at replication have provided conflicting results. Recently, we undertook a meta-analysis of Genome Wide Association Study (GWAS) results for lung function measures in 20,288 individuals from the general population (the SpiroMeta consortium). OBJECTIVES: To comprehensively analyse previously reported genetic associations with lung function measures, and to investigate whether single nucleotide polymorphisms (SNPs) in these genomic regions…
Mapping inequalities in exclusive breastfeeding in low- and middle-income countries, 2000-2018
2021
Exclusive breastfeeding (EBF)—giving infants only breast-milk for the first 6 months of life—is a component of optimal breastfeeding practices effective in preventing child morbidity and mortality. EBF practices are known to vary by population and comparable subnational estimates of prevalence and progress across low- and middle-income countries (LMICs) are required for planning policy and interventions. Here we present a geospatial analysis of EBF prevalence estimates from 2000 to 2018 across 94 LMICs mapped to policy-relevant administrative units (for example, districts), quantify subnational inequalities and their changes over time, and estimate probabilities of meeting the World Health …
Characterization of Legal Psychology through psychology journals included in Criminology & Penology and Law categories of Web of Science
2017
[EN]: The objective of this work is to learn about the most relevant aspects that characterize contemporary Legal Psychology throughout the study of journals included in the WoS between the years 2009 and 2014 re-lated with the area of Psychology. The number of selected publications is 16, mainly from the USA and Great Britain. The results show an increase in the number of works and authors, a greater collaboration and a growth in medium productors. It exists a major presence of men in editorial boards and as authors, outstanding the figures of T. Ward in 2009 and A. Vrij in 2014. According to the analysis of key words the most relevant themes during these years have been Crime, Conduct, Wo…
Pleistocene allopatric differentiation followed by recent range expansion explains the distribution and molecular diversity of two congeneric crustac…
2021
AbstractPleistocene glaciations had a tremendous impact on the biota across the Palaearctic, resulting in strong phylogeographic signals of range contraction and rapid postglacial recolonization of the deglaciated areas. Here, we explore the diversity patterns and history of two sibling species of passively dispersing taxa typical of temporary ponds, fairy shrimps (Anostraca). We combine mitochondrial (COI) and nuclear (ITS2 and 18S) markers to conduct a range-wide phylogeographic study including 56 populations of Branchinecta ferox and Branchinecta orientalis in the Palaearctic. Specifically, we investigate whether their largely overlapping ranges in Europe resulted from allopatric differe…
The Valencia Eustress-Distress Appraisal Scale (VEDAS): Validation of the Italian Version
2018
© 2018 by the authors. The aim of this study is to validate the Italian version of the Valencia Eustress-Distress Appraisal Scale (VEDAS). Two hundred and thirty-two Italian workers were involved in the study. Dimensionality, reliability, and concurrent validity were analyzed. Confirmatory factor analysis supported a four-dimensional structure. In addition, the Italian version of the scale showed good internal consistency and validity. The results indicate that the Italian version of the VEDAS is a valid instrument for measuring eustress and distress appraisal in the Italian context. ispartof: SUSTAINABILITY vol:10 issue:11 status: published

Seminar groups as part of first-semester mathematics teaching: What did the students learn?
2018
International audience; In this study, the learning encouraged by teaching activities in a small-group setting was investigated through the analysis of students' responses to survey and interview questions. The results indicate that the students perceived an increased ability to communicate mathematics in written form, but to a lesser extent developed their ability to discuss mathematics and build conceptual understanding.
