Status, distribution and conservation of Kentish plover <em>Charadrius alexandrinus</em> (Aves, Charadriiformes) in Sicily
2021
The Kentish Plover Charadrius alexandrinus is a sensitive species whose national breeding population has been undergoing a sharp decrease, up to 50%, in 2010 compared to the previous decade. Due to the lack of updated data and fragmented knowledge about its current status and distribution in Sicily, a specific and accurate monitoring of this species was carried out during the years 2018 and 2019. About 230 km of coastline and 64 UTM squares 10x10 km were investigated during the breeding seasons, and a total of 205-287 pairs have been estimated for the whole region, distributed in 41 UTM squares (including the island of Favignana). Pairs are mainly concentrated in the complex of “Saline di T…
Metazoan parasite communities and diet of the velvet belly lantern shark Etmopterus spinax (Squaliformes: Etmopteridae): a comparison of two deep-sea…
2014
By combining an examination of stomach contents yielding a snapshot of the most recent trophic niche and the structure of parasite communities reflecting a long-term feeding niche, this study aimed at gaining more comprehensive information on the role of the small-sized deep-water velvet belly lantern shark Etmopterus spinax in the local food webs of the Galicia Bank and the canyon and valley system of the Aviles Canyon, which have been both proposed for inclusion in the Natura 2000 network of protected areas. As far as is known, this study provides the first comparative parasite infracommunity data for a deep-sea shark species. Component parasite communities in E. spinax were relatively ri…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021.

The informational role of thin options markets: Empirical evidence from the Spanish case
2016
This study investigates the informational role of thin options markets, specifically the Spanish options market. Firstly, we examine the effect of options markets by analysing stock market reaction to earnings news, conditional on the availability of options markets. Secondly, we examine options trading activity before the release of earnings news (including the announcement period). The results show that the impact on prices before the earnings release is significantly bigger when options trading is available. Moreover, the dissemination of earnings news is associated with significant unusual activity in the options market due to informed trading, especially when the earnings surprise is h…
Temptation and commitment in the laboratory
2010
Temptation and self-control in intertemporal choice environments are receiving increasing attention in the theoretical economics literature. Nevertheless, there remains a scarcity of empirical evidence from controlled environments informing behavior under repeated temptations. This is unfortunate in light of the fact that in many natural environments, the same temptation must be repeatedly resisted. This paper fills that gap by reporting data from a novel laboratory study of economic decisions under repeat temptations. Subjects are repeatedly offered an option with instantaneous benefit that also entails a substantial reduction to overall earnings. We show that this option is "tempting" in …
Revista de educación

Número extraordinario 2006, con el título: PISA. Programa para la Evaluación Internacional de Alumnos. Resumen basado en el de la publicación Se analiza el proyecto del Programa para la Evaluación Internacional de Alumnos (PISA) como instrumento para la mejora del aprendizaje, la enseñanza y los currículos. Se constata la falta de provecho, las interpretaciones distorsionadas y perjudiciales para la extensión de una educación de calidad. Asimismo, se procede a mostrar las virtualidades del proyecto y su coherencia con las aportaciones de la investigación educativa. Se indican algunas estrategias para que juegue su papel de instrumento de mejora del proceso de enseñanza-aprendizaje. Por otra…
Cuadernos de pedagogía
2008
La publicación del informe PISA 2006 ha dado lugar a las mismas abundantes críticas y lamentaciones acerca del fracaso de nuestro sistema educativo -y, en particular, de la educación científica- que provocó el informe de 2003, a causa del lugar que ocupa España en el conjunto de países de la OCDE. No vamos a repetir aquí los argumentos que invalidan estas injustificadas lecturas de los resultados presentados en el informe: como mostrábamos en otro trabajo (Gil Pérez y Vilches, 2006), tienen la misma validez que sostener, cuando las notas medias de dos grupos de estudiantes en una determinada materia son, respectivamente, 5.5 y 4.9, que el primero ha funcionado mucho mejor que el segundo.
Quelle éducation pour les ruraux des pays en voie de développement ?
1985
International audience; De nombreux pays en voie de développement s'interrogent sur leur politique d'éducation vis-à-vis des ruraux, et l'on observe, depuis quelques années, la mise en place de réformes dont les effets risquent d'être plus dommageables que ceux des systèmes que l'on prétend ainsi corriger. le problème tourne autour de la question centrale du degré de spécificité que doit avoir l'école rurale pour répondre aux besoins du développement en général, et de développement agricole en particulier. Or, les évolutions en cours tendent à rechercher plus de spécificité, et l'auteur se propose de montrer que cette voie est dangereuse et a peu de chances de produire les effets positifs e…
