High-to-low (Regional) fertility transitions in a peripheral european country: The contribution of exploratory time series analysis

2021

Diachronic variations in demographic rates have frequently reflected social transformations and a (more or less evident) impact of sequential economic downturns. By assessing changes over time in Total Fertility Rate (TFR) at the regional scale in Italy, our study investigates the long-term transition (1952–2019) characteristic of Mediterranean fertility, showing a continuous decline of births since the late 1970s and marked disparities between high- and low-fertility regions along the latitude gradient. Together with a rapid decline in the country TFR, the spatiotemporal evolution of regional fertility in Italy—illustrated through an exploratory time series statistical approach—outlines th…

Long-term impact of rainfed agricultural land abandonment on soil erosion in the Western Mediterranean basin

2018

[EN] Land abandonment is widespread in the Mediterranean mountains. The impact of agricultural abandonment results in a shift in ecosystem evolution due to changes in soil erosion, but little is known about long-term soil and water losses. This paper uses 11 years of measurements in two paired plots (abandoned vs control) with four subplots to determine how soil and water losses evolved after abandonment within an agricultural parcel. For two years (2004¿2005) both plots were under tillage, and after 2006 one plot was abandoned. The monitored plots measured runoff and sediment concentration after each rainfall event.

Time-varying dependence between stock and government bond returns: International evidence with dynamic copulas

2015

This paper investigates the dependence pattern between stock and long-term government bond returns for a wide range of developed countries over the last two decades by using a dynamic DCC-GARCH-copula model. This approach allows obtaining a flexible and comprehensive description of the time variation in the linkage between stock and bond markets. The empirical results show that the dependence structure between stock and 10-year government bond returns varies significantly over time for most countries. In particular, a positive stock-bond association is observed during the 1990s, while the relationship becomes negative from the early 2000s,supporting the presence of flight-to-quality effects…

Concepciones docentes sobre educación inclusiva. Diferencias entre etapas educativas

2023

La presente investigación tiene como objetivo analizar y comparar las concepciones sobre la inclusión que tienen los docentes de infantil, primaria y secundaria. 270 docentes cumplimentaron el Cuestionario de Valoración Docente de la Inclusión Educativa (CEFI-R), centrado en evaluar las concepciones docentes sobre la diversidad, la metodología, los apoyos y la participación de la comunidad en la inclusión educativa. Los resultados evidencian que los docentes de educación infantil y primaria presentan unas concepciones más favorables hacia la inclusión en comparación al profesorado de secundaria. Resulta necesario a…

The Impact of service-learning on the training of pre-service teachers: analysis from a physical education subject

2015

This paper discusses the effects of the use of service learning in pre-service teachers (PSTs). This methodology has been applied for two academic years at a Spanish university, providing a direct service for children with special educational needs (SEN) through motor and expressive games. We used Butin's model for the analysis of data collected through written reflections. The results show significant academic and personal learning, especially in areas useful for future teachers. The paper also proposes an extension (subcategories) of the original explanatory model.

UN APPROCCIO INQUIRY BASED ALLO SVOLGIMENTO DEI LABORATORI DIDATTICI DI FISICA NEL CORSO DI LAUREA IN SCIENZE DELLA FORMAZIONE PRIMARIA

Il tema di questo lavoro di ricerca svolto tra gli anni 2014-2016 riguarda una sperimentazione sul ruolo di approcci all'apprendimento basati su processi di investigazione scientifica, nella formazione dei docenti di Scuola Primaria e dell'Infanzia. Tali approcci didattici sono noti nella letteratura specializzata con il nome di Inquiry Based Science Education (IBSE). La sperimentazione è stata condotta con gli studenti del corso di laurea in Scienze della Formazione Primaria dell’Università degli Studi di Palermo, corso di laurea abilitante per l’insegnamento nella scuola dell’infanzia e primaria. Inquiry Based Science Education, pre-service primary school teacher education.

Estadística (Estadística descriptiva en Psicología) (2009-2010)

2009

La finalidad general de la asignatura es la de proveer procedimientos para dar respuesta a las cuestiones de interés para los psicólogos mediante análisis estadístico de datos, y en consecuencia tiene un carácter teórico-práctico. Las técnicas de análisis de datos son requisito para otras asignaturas básicas del plan de estudios como son Psicometría y Diseños de Investigación así como otras materias optativas. También son requisito para la realización de investigación empírica en otras materias y áreas de conocimiento así como para la comprensión teórica de las bases del conocimiento empírico del comportamiento.

Foreign-owned firms around the world: A comparative analysis of wages and employment at the micro-level

2013

Abstract This paper provides the first microeconomic cross-country analysis of the effects of foreign ownership on wages, employment and worker turnover rates. Using firm-level and linked worker-firm data, we apply a standardised methodology for three developed (Germany, Portugal, UK) and two emerging economies (Brazil, Indonesia). We find that wage effects are larger in developing countries, and that for each country the largest effect on wages comes from workers who move from domestic to foreign firms. Employment growth after foreign takeover is concentrated in high-skill jobs. In contrast to widespread fears, there is no evidence that wage gains come at the expense of greater job insecur…

Choosing among alternative technological strategies: an empirical analysis of formal sources of innovation

2003

Abstract This work aims to offer a detailed conceptual and empirical analysis of the inter-firm differences in deciding the composition of their technological efforts. Using data for Spanish firms in the period 1990–1996, the study begins with the standard analysis of the determinants of innovative investment, then moves on to the less analysed question of the determinants of the generate versus import alternative and ends with a novel analysis of the characteristics which lead firms to organise research internally as compared to the possibility of contracting R&D services externally. In contrast to standard practice, the econometric approach takes into account the existence of non-linearit…
