Monumental chestnut trees: source of genetic diversity, cultural and landscape value
2019
The mtonumental trees are unique individuals tof venerable age and ctonsiderable size, which represent a heritage tof inestimable histtorical, cultural, landscape, and scientific value ftor the territtory. They alsto ctonstitute a stource tof genetic diversity which ctonfers them ltongevity and ability tto adapt tto climate and envirtonmental changes. In this ctontext, studies ton centennial trees can be useful ftor interpretatiton tof species histtory as migratiton events, selectiton and anthrtoptogenic actiton. The aim tof this research was tto evaluate the genetic variability tof ancient Castanea sativa trees and relate them tto actual natural/naturalized ptopulatitons and varieties in t…

Revista electrónica interuniversitaria de formación del profesorado
2013
El objetivo de este trabajo fue analizar la actitud hacia la inclusión educativa de los futuros docentes. Doscientos setenta y cuatro estudiantes del Grado de Magisterio de Infantil y Primaria y del Máster de Educación Especial de la Universitat de Valéncia cumplimentaron una adaptación de la escala ORI (Opinions Relative to Integration of Students with Disabilities Scale). Se analizó la fiabilidad y estructura factorial del cuestionario. Se comparó la puntuación en la escala entre los estudiantes de grado y de máster; entre los estudiantes de Grado de Magisterio de Educación Infantil y el de Educación Primaria; y entre los estudiantes de grado antes y después de cursar la asignatura Necesi…
Innowacyjne podejście do kształcenia przyszłych nauczycieli
2015
W artykule przedstawiono autorskie doświadczenia wykorzystania potencjału pedagogicznych pomiarów w celu udoskonalenia kształcenia przyszłych nauczycieli. Otrzymane wyniki konstatowały, że właśnie zadania w testowej formie mogą stać się ważnym ogniwem nauki przyszłych specjalistów. Biorąc jako podstawę do opracowania zadań w testowej formie, prace E.Ł.Biełkina i teorię pedagogicznych pomiarów W.Awanesowa, według dyscyplin psychologiczno-pedagogicznego bloku, opracowano system zadań różnegostopnia złożoności, a także przedstawiono metodykę realizacji tego systemu w procesie zawodowego przygotowania pedagogicznych kadr. W artykule ukazano wyniki praktycznej realizacji opracowanego systemu w p…

Two Relevant Forecasting Problems for Practitioners in Finance: Equity Risk Premium and Non-Performing Loans
2021
The thesis aims to substantiate whether macroeconomic factors indicators are relevant to predict both in-sample and out-of-sample assets' future performance focusing on two well-studied themes in financial economics and banking: First, the ability to predict the equity risk premium, and second, the macroeconomic determinants of non-performing loans (NPL) rates. The dissertation is divided in three chapters. Chapter 1, entitled "Forecasting the equity risk premium in the European Monetary Union", investigates the capacity of multiple economic and technical variables to predict the Euro area equity risk premium. The chapter examines the performance of several variables that could be good pred…
Item Response Trees: a recommended method for analyzing categorical data in behavioral studies
2015
Behavioral data are notable for presenting challenges to their statistical analysis, often due to the difficulties in measuring behavior on a quantitative scale. Instead, a range of qualitative alternative responses is recorded. These can often be understood as the outcome of a sequence of binary decisions. For example, faced by a predator, an individual may decide to flee or stay. If it stays, it may decide to freeze or display a threat and if it displays a threat, it may choose from several alternative forms of display. Here we argue that instead of being analyzed using traditional nonparametric statistics or a series of separate analyses split by response categories, this kind of data ca…
Machine learning for mortality analysis in patients with COVID-19
2020
This paper analyzes a sample of patients hospitalized with COVID-19 in the region of Madrid (Spain). Survival analysis, logistic regression, and machine learning techniques (both supervised and unsupervised) are applied to carry out the analysis where the endpoint variable is the reason for hospital discharge (home or deceased). The different methods applied show the importance of variables such as age, O2 saturation at Emergency Rooms (ER), and whether the patient comes from a nursing home. In addition, biclustering is used to globally analyze the patient-drug dataset, extracting segments of patients. We highlight the validity of the classifiers developed to predict the mortality, reaching…
Central limit theorem for bifurcating Markov chains under L 2 -ergodic conditions
2021
Bifurcating Markov chains (BMC) are Markov chains indexed by a full binary tree representing the evolution of a trait along a population where each individual has two children. We provide a central limit theorem for additive functionals of BMC under L 2-ergodic conditions with three different regimes. This completes the pointwise approach developed in a previous work. As application, we study the elementary case of symmetric bifurcating autoregressive process, which justify the non-trivial hypothesis considered on the kernel transition of the BMC. We illustrate in this example the phase transition observed in the fluctuations.
