Extreme value theory versus traditional GARCH approaches applied to financial data: a comparative evaluation
2013
Although stock prices fluctuate, the variations are relatively small and are frequently assumed to be normally distributed on a large time scale. But sometimes these fluctuations can become determinant, especially when unforeseen large drops in asset prices are observed that could result in huge losses or even in market crashes. The evidence shows that these events happen far more often than would be expected under the generalised assumption of normally distributed financial returns. Thus it is crucial to model distribution tails properly so as to be able to predict the frequency and magnitude of extreme stock price returns. In this paper we follow the approach suggested by McNeil and Frey …
The TIER on Spanish Banks
2015
This paper studies the determinants that have affected the solvency of Spanish credit institutions. Six hypotheses with data from the annual accounts of credit institutions that ranges from 2004 to 2011 are contrasted. Econometric panel data models are used. The results show that the dependence on wholesale financial markets, the NPLs and provisions for impairment, contribute negatively to the solvency. The increase in: portfolio of assets, real estate investments, leverage, staff costs and administrative and interest margin and other income, serve to strengthen solvency
Desarrollo de un modelo de evapotranspiración global con datos de satélite y de re-análisis
2021
La cuantificación de la evapotranspiración (ET) es fundamental para el estudio de los procesos hidrológicos, caracterización climática y agronómica, así como para la aplicación en modelos de cambio climático, y la gestión de los recursos hídricos. Cabe destacar, la importancia del conocimiento de este parámetro en el control de inundaciones y sequías, en la planificación de obras de infraestructura, entre otras. Los factores que intervienen en el proceso de ET son diversos, variables en el tiempo y en el espacio, por lo tanto, cobran relevancia los datos de satélite, debido a que con ellos se puede obtener una variación espacio-temporal de los componentes del ciclo hidrológico a diferentes …
Hospitalisation Cost of Patients with Diabetic Foot Ulcers in Valencia (Spain) in the Period 2009–2013: A Retrospective Descriptive Analysis
2018
Ulcers are the main cause of hospitalisation and clinical complications in patients with diabetes. We analyse the length and cost of hospital stay of patients with diabetic foot ulcers, taking into consideration that hospitalisation and, if necessary, amputation represent the greatest area of expense to the healthcare system for such patients. This analysis focuses on the treatment provided to these patients in public hospitals in the region of Valencia (Spain), registered in the Spanish Minimum Basic Data Set, during the period 2009&ndash
Bayesian calibration of the nitrous oxide emission module of an agro-ecosystem model
2008
1. NitroEurope Open Science Conference on Reactive Nitrogen and the European Greenhouse Gas Balance ; Ghent (Belgique) - (2008-02-20 - 2008-02-21) / Conférence; Nitrous oxide (N2O) is the main biogenic greenhouse gas contributing to the global warming potential (GWP) of agro-ecosystems. Evaluating the impact of agriculture on climate therefore requires a capacity to predict N2O emissions in relation to environmental conditions and crop management. Biophysical models simulating the dynamics of carbon and nitrogen in agro-ecosystems have a unique potential to explore these relationships, but are fraught with high uncertainties in their parameters due to their variations over time and space. H…
Leratiomyces ceres (Strophariaceae, Basidiomycota), new to Poland
2019
<em>Leratiomyces ceres</em>, an extra-European species hitherto unknown in Poland, was identified in a public park in Rybnik City (SW Poland). The first Polish collections of the fungus were studied using macroscopic and microscopic features. A brief description and illustration of the species, based on Polish specimens, are presented. The ecology and characteristics distinguishing <em>L. ceres</em> from related <em>Leratiomyces</em> species are also discussed.
Reliģisko svētku statuss Latvijā
2020
Maģistra darbā „Reliģisko svētku statuss Latvijā” ir pētīti jautājumi, kas saistās ar svētku dienu tiesisko regulējumu atbilstoši normatīvo aktu prasībām. Maģistra darba mērķis ir izvērtēt spēkā esošo regulējumu par svētku, atceres un atzīmējamajām dienām. Lai sasniegtu mērķi ir nepieciešams izvērtēt svētku dienu tiesisko regulējumu no valsts pirmās neatkarības laika līdz mūsdienām un salīdzināt svētku dienu tiesisko regulējumu citās valstīs. Pētījuma rezultātā iegūtā informācija ļaus labāk izprast un izanalizēt iespējamos grozījumus likumā „Par svētku, atceres un atzīmējamām dienām”. Tēma šobrīd ir īpaši aktuāla, ņemot vērā to, ka kopš 1990. gada katras Saeimas deputāti iesniedz identiskus…
Treatment of recurrent aphtous stomatitis: A systematic review
2022
Background: Recurrent Aphtous Stomatitis (RAS) is the most common process affecting the oral mucosa. It is painful, multifactorial and generally recurrent. The aim of this systematic review is to know the last treatment approaches and their effectivity.Material and Methods: we compared the outcome of different kind of treatments in terms of the improvement of the lesions, reduction of the size of those lesions and the time needed for their healing. Inclusion criteria were: clinical trials, articles written in English or Spanish and published less than 5 years ago.Results: we used the following keywords: treatment, aphtous stomatitis, canker sores; combined with Bool-ean operators AND y OR. …

Recent visigothic coin findings. Gold and bronze in the north of Cáceres
2017
El artículo pretende documentar una serie de monedas visigodas de oro y bronce encontradas fortuitamente dentro de la provincia de Cáceres, todas ellas de forma aislada y en solitario. La procedencia exacta de todas las piezas no se conoce del todo, aunque están circunscritas con seguridad a Cáceres. Además, dos de las monedas son inéditas: un triente pseudo-imperial a nombre de Justiniano I y un tremís de Égica y Witiza procedente de Acci. The paper aims to document a series of Visigoth gold and bronze coins fortuitously found in the province of Cáceres, all of them isolated and alone. The exact origin of all the coins is not fully known, but it is confined surely within Cáceres. Furthermo…
