Almost sure central limit theorems for random ratios and applications to lse for fractional ornstein–uhlenbeck processes
2012
We investigate an almost sure limit theorem (ASCLT) for sequences of random variables having the form of a ratio of two terms such that the numerator satisfies the ASCLT and the denominator is a positive term which converges almost surely to 1. This result leads to the ASCLT for least square estimators for Ornstein-Uhlenbeck process driven by fractional Brownian motion.
Urban Sprawl and Northern European Residential Tourism in the Spanish Mediterranean Coast
2016
Residential tourism from Northern European countries has influenced the process of urban development in the Spanish Mediterranean coast. We explain the recent urban growth in Spain (or “Spanish house bubble”) and then show the main characteristics of the influx of citizens from other European countries richer than Spain, especially into the Spanish Mediterranean coast and specifically into the Costa Blanca region. Finally we demonstrate the relationship between the development of residential tourism and the growth of urban sprawl in the Spanish Mediterranean coast and we analyze some of its consequences for the region..
Long-term organic farming on a citrus plantation results in soil organic carbon recovery
2019
[ES] Se ha demostrado que el manejo del suelo bajo agricultura ecológica puede aumentar el contenido de carbono orgánico en el suelo moderando el incremento de los gases de efecto invernadero, pero hasta la fecha las evaluaciones cuantitativas basadas en mediciones a largo plazo han sido escasas, especialmente bajo condiciones mediterráneas. En esta investigación se examinaron los cambios en el contenido de carbono orgánico como respuesta a la agricultura ecológica con cobertura vegetal en una plantación de cítricos en el área mediterránea, utilizando una base de datos de 21 años. El incremento de contenido de carbono orgánico en el suelo fue más evidente tras cinco años desde el cambio del…
Lluvias torrenciales y cambios geomórficos en una pequeña cuenca de montaña : el barranco de la Cuesta de la Vega (Valencia)
2013
In this paper the effects of great magnitude -450 mm.- as well as high continued intensity -> 90 mm. for 3h.- storm-rains have been studied for a small mediterranean drainage basin (Ayora, Valencia). Such rains caused anormal flows -between 11.2 y 38.2 m3/sec/km2- and the reactivation of erosiona! and aggradational processes, especially at flat bottomed valleys with terrace culture, where new channels were formed. Severa! types of deposits and erosiona! phenomena are established; among them valley amplitude, local slopes, culture abandonment (in a positive sense ), and valley floor terracing are pointed out.
Four-year soil erosion rates in a running-mountain trail in eastern Iberian Peninsula
2019
During the last decades, the use of mountain trails for running is more and more popular. New trails are opened to allow the runners to practice and compete. This form of human impact on the landscape is new as the new trails do not follow the conservation strategies in design and maintenance as traditional mountain trails constructed by farmers, shepherds and muleteers do. This impact of sport events in nature is not measured and we know little about this impact on vegetation, fauna and soils. We surveyed in September 2018 a trail that was opened in September 2014 and was used for four official mountain trail races, and for training by local runners. Our interviews with organizers and user…
Las crecidas en ramblas valencianas mediterráneas
2001
This paper takes into account the characterisation of ephemeral stream hydrology from Mediterranean environments. The heavy floods that these countries suffer are due to firstly, the physical watershed features (steep slopes, scarced vegetation cover and thin soils) and, secondly, to the intense and variable rainfall. Large quantities of precipitation fall in a matter of hours, or even minutes, over very steep catchments, causing catastrophic flash-floods, with very pointed hydrographs and short time lags. Using hydrological daily data from the Rambla de la Viuda basin and five-minute data from both Barranc de Carraixet and Rambla de Poyo basins, we have analysed the rainfall- runoff proces…

Identification of a multi-reassortant G12P[9] rotavirus with novel VP1, VP2, VP3 and NSP2 genotypes in a child with acute gastroenteritis.
2015
The G12 rotavirus genotype is globally emerging to cause severe gastroenteritis in children. Common G12 rotaviruses have either a Wa-like or DS-1-like genome constellation, while some G12 strains may have unusual genome composition. In this study, we determined the full-genome sequence of a G12P[9] strain (ME848/12) detected in a child hospitalized with acute gastroenteritis in Italy in 2012. Strain ME848/12 showed a complex genetic constellation (G12-P[9]-I17-R12-C12-M11-A12-N12-T7-E6-H2), likely derived from multiple reassortment events, with the VP1, VP2, VP3 and NSP2 genes being established as novel genotypes R12, C12, M11 and N12, respectively. Gathering sequence data on human and anim…
El componente de selección adversa de la horquilla de precios cotizada: una revisión de los modelos de estimación
2005
-Jose.E.Farinos@uv.es -Ana.M.Ibanez@uv.es Una de las principales preocupaciones en el área de la microestructura del mercado ha sido la estimación de los componentes no observables de la horquilla de precios a partir de las series de datos que proporcionan los mercados financieros, despertando quizá un mayor interés el de selección adversa por la implicaciones que supone la existencia del mismo. Esto ha provocado el desarrollo de numerosos modelos empíricos que, basándose en las propiedades estadísticas de las series de precios, proporcionan dichas estimaciones. La mayor disponibilidad de datos existentes en los mercados ha permitido el desarrollo en los últimos años de modelos basados en t…
Performance and international investments in microfinance institutions
2013
Preprint of the published version of an article from Strategic Change Using data from 319 microfinance institutions (MFIs) in 68 developing countries, we study the degree to which international debt investments are related to the financial and social performances of MFIs. We find that commercial investments are mainly related to financial performance and level of professionalisation of the MFIs. The targeting of women is not a priority, even though international commercial investors target MFIs that provide small loans. Subsidised investments, however, are mainly driven by the targeting of women, while financial performance and the level of professionalisation of the MFI is not a priority.
