No linealidad y asimetría en el proceso generador del Índice Ibex35
2013
This paper analyzes the behavior of Ibex35 from January 1999 to December 2001, in order to check if it follows a different process from random walk so its return is not a white noise and it can be predictable, against the efficient market hypothesis. For that, a nonlinear generating process of return will be considered and a STAR-APARCH model will be specified. This model allows a nonlinear behavior in the conditional mean and in the conditional variance. The empirical results show that the Ibex35 follows a nonlinear and asymmetric process, both in the conditional mean as in the conditional variance, so the weak-version of efficient market hypothesis is rejected.

Heterogeneidad en el impacto de la política de becas en la escolaridad secundaria postobligatoria en España: un análisis por subgrupos poblacionales
2013
El presente trabajo analiza el impacto de las becas sobre la probabilidad de finalizar con éxito el nivel secundario postobligatorio en España en el caso de diferentes subgrupos poblacionales. Se aplica un diseño cuasiexperimental (Propensity score matching) a partir de la Encuesta de Condiciones de Vida (ECV-2006). Los resultados confirman la existencia de efectos diferenciales positivos (con relación al impacto medio) de la política educativa en el caso de las mujeres y de los alumnos provenientes de hogares desfavorecidos, demostrando la existencia de heterogeneidad en el impacto de la política analizada.
On the property of diffusion in the spatial error model.
2005
International audience; The aim of this paper is to illustrate the property of global spillover effects in the first-order spatial autoregressive error model and the associated diffusion process of spatial shocks. An application is provided on a sample of 145 regions over 1989–1999 and highlights the most influential regions.
A microeconometric analysis of the springboard subsidiary: The case of Spanish firms
2015
Abstract This paper provides a microeconometric analysis of the distinctive characteristics of springboard subsidiaries that have a positive impact on the subsidiaries’ performance. Based on panel data estimations for subsidiaries of European multinational companies with a presence in Spain, the authors found that if the subsidiary is located in the springboard country, then the performance improvement (increase in profit margin) of the subsidiary is about 49 percentage points. When the Spanish subsidiary is considered a springboard subsidiary, its performance is 7.7 percentage points higher than the performance of other subsidiaries that are not springboard subsidiaries. If the subsidiary …
The extended CC2 model ECC2
2013
We present a size-extensive extension to the CC2 model that avoids the complications with quasi-degeneracies that are present in the CC2 model and related perturbation theory-based approaches. The formulation also provides a consistent model for treating different parts of a molecular system at different levels of electron correlation. Such a subsystem approach leads to large reductions in the computational requirements without compromising the accuracy. In this initial study, we focus on static molecular properties. © 2013 Copyright Taylor and Francis Group, LLC.
Sliding-end-labelling
1986
Abstract A method, termed ‘sliding-end-labelling’, has been devised to avoid a frequent artifact in nucleosome positioning by indirect end labelling, namely the appearing of DNA fragments originated by two nuclease cuts, one of them lying within the region covered by the probe. The method is applied to the nucleosome positioning in the yeast SUC2 gene for invertase.
Product and Labour Market Regulations, Production Prices, Wages and Productivity
2016
ACLN; International audience; This study is an attempt to evaluate the effects of product and labour market regulations on industry productivity through their various impacts on changes in production prices and wages. In a first stage, the estimation of a regression equation on an industry*country panel, with controls for country*industry and country*year fixed effects, show that multi-factor productivity is negatively and significantly influenced by both indicators of industrial prices from same industry and weighted average of industrial prices from other industries, and by indicators of country wages weighted by industry labour shares for low and high skilled workers. In a second stage, …
What is the impact of rerouting a cancer diagnosis from emergency presentation to GP referral on resource use and survival? Evidence from a populatio…
2018
Background Studies on alternative routes to diagnosis stimulated successful policy interventions reducing the number of emergency diagnoses and associated mortality risk. A dearth of evidence on the costs of such interventions might prevent new policies from achieving more ambitious targets. Methods We conducted a retrospective cohort study on the population of colorectal (88,051), breast (90,387), prostate (96,219), and lung (97,696) cancer patients diagnosed after a GP referral or an emergency presentation and reported in the Cancer Registry of England. Resource use and survival were compared 1 year before and 5 years after diagnosis (3 years for lung), including the costs of GP referrals…
γ2-Adaptin, a Ubiquitin-interacting Adaptor, Is a Substrate to Coupled Ubiquitination by the Ubiquitin Ligase Nedd4 and Functions in the Endosomal Pa…
2008
gamma2-Adaptin is a putative member of the clathrin adaptor protein family with unknown physiological function. We previously reported that gamma2-adaptin acts as a ubiquitin receptor by virtue of its ubiquitin-interacting motif. Here we demonstrate that this motif mediates a specific physical interaction with the ubiquitin ligase Nedd4 and promotes ubiquitination of gamma2-adaptin. By mapping regions of Nedd4 involved in binding to gamma2-adaptin, we identified its C2 domain to be essential, whereas the WW and HECT domains are dispensable. Consistent with this, we uncovered that the C2 domain of Nedd4 is ubiquitinated itself and as such is recruited by the ubiquitin-interacting motif of ga…
Validación de un Cuestionario Multidimensional de Adaptación a la Enfermedad para Pacientes Renales en Diálisis (CMAE-RD) diseñado a partir de un cue…
2020
espanolObjetivos: El objetivo de este trabajo es estudiar las propiedades psicometricas de un cuestionario multidimensional de adaptacion a la enfermedad para pacientes con enfermedad renal en dialisis (CMAE-RD).Metodos: Esta herramienta esta disenada para ser administrada por un profesional de la psicologia en forma de entrevista semiestructurada y fue disenado a partir de un cuestionario previo para pacientes oncohematologicos. Un total de 113 pacientes en hemodialisis fueron entrevistados mediante el CMAE-RD y completaron dos cuestionarios adicionales con propositos de validacion: el HADS (para evaluar ansiedad y depresion) y el CDRISC-2 (para evaluar resiliencia).Resultados: La consiste…
