Novedades taxonómicas y nomenclaturales para la flora valenciana, II
2010
Continuando con la actualización taxonómica y nomenclatural de la flora valenciana, se proponen diez combinaciones nuevas y un nombre nuevo para táxones y nototáxones que crecen en el Mediterráneo occidental. Además, se designa un epitipo para Sideritis × angustifolia Lag., híbrido sobre cuya identidad ha existido gran controversia, y un lectotipo para Globularia linifolia Lam. Del mismo modo, se discute la citación correcta del lugar y fecha de publicación de cuatro táxones más. Taxonomic and nomenclatural novelties concerning the Valencian flora (eastern Spain), II: As a part of the taxonomical and nomenclatural update of vascular flora of the Valencian Community, ten new combinations and…
What Do We Know About the Second Moment of Financial Markets?
2021
Recent research shows that the vast majority of scientific studies published in leading finance journals fails scientific replication (Hou, Xue, and Zhang, 2020; Harvey, Liu, and Zhu; 2016). This study argues that p-hacking, publication pressure and the selection bias from leading finance journals are perhaps not the underlying root cause for this issue. We show that standard methodologies often used in finance research are inevitably sample-specific due to the very nature of financial markets. While the consensus of earlier research postulates a rejection of the time-honored Levy hypothesis, our results strongly indicate that the variance of variance does not exist in any of the financial …
L’Ordine di Malta nella storiografia italiana. La fine di una latitanza?
2021
Il saggio offre una ricognizione critica degli studi sull’Ordine di Malta pubblicati in Italia negli ultimi cinquant’anni, mettendo in rilievo le connessioni con la storiografia internazionale, quella iberica in particolare. Emerge un quadro di ricerche che, nonostante gli stimolanti temi di indagine e l’interesse delle fonti consultate, sono ancora caratterizzate da un approccio marcatamente settoriale. In conclusione, si propone un’auspicabile collaborazione interdisciplinare tra storici e giuristi al fine di allargare il contesto spaziale e cronologico degli studi sull’Ordine. This paper provides an historiographical overview of Italian studies on the Order of Malta, which have been publ…

Option-Implied Volatility Spillovers between Risk Factors in FX Markets and States of the Global Economy
2016
This study employs option price data to back out the implied portfolio volatilities of the dollar and carry trade risk factors of the G-10 currencies. To investigate expected volatility spillover effects between risk factors in FX markets, we extend Grobys (2015) and Diebold and Yilmaz (2009) by constructing expected volatility spillover indices based upon the forecast-error variance decomposition of Vector-Autoregression models employing option-implied portfolio volatilities. Surprisingly, the dollar and carry trade risk factors that are orthogonal in the first moment exhibit strong stochastic interrelations in the second expected moment. Our findings indicate that expected high spillover …
Datos sobre las tiledas ibéricas (Tilio-Acerion Klika 1955)
2008
Se aportan datos sobre las tiledas ibéricas, que se agrupan en tres asociaciones fitosociológicas dentro de la alianza Tilio-Acerion: Hedero-Tilietum platyphylli (pirenaica y prepirenaica), Helleboro occidentalis-Tilietum platyphylli (orocantábrica) y Ononido aragonensis-Tilietum platyphylli (oroibérica). En el seno de la primera se proponen dos nuevas subasociaciones: la típica, fraxinetosum excelsioris (pirenaica, silicícola, con estratos arbóreo y herbáceo muy ricos), y festucetosum gautieri (prepirenaica, calcícola y más pobre florísticamente), que pretenden explicar algunas variaciones observadas en su área de distribución. El nombre Ononido-Tilietum se propone como nuevo para remplaza…
Old-timers and newcomers: The shrews and heterosoricids from the Ribesalbes-Alcora Basin (East of Spain)
2019
The zone of Araia d’Alcora in the Ribesalbes-Alcora Basin (Spain, early Miocene, biozone C, MN 4) yielded a relatively rich assemblage of shrews for an Iberian site, composed by Oligosorex thauensis, cf. Soricella discrepans, Paenelimnoecus micromorphus and Heterosorex neumayrianus. The fossils of O. thauensis, the most abundant taxon, significantly increase our knowledge regarding the morphology of the species. It signals the last known occurrence of this shrew and extending its record to a MN4 site. This species is competing with other shrews in the studied sites. Paenelimnoecus micromorphus is recorded for the first time in the Iberian Peninsula. Soricella discrepans is a typical species…
La Cova de Dalt del Tossal de la Font (Vilafamés, Castellón): conclusiones preliminares de las intervenciones arqueológicas (1982-1987 / 2004-2012)
2013
Resumen Las excavaciones llevadas a cabo en el yacimiento de la Cova de Dalt del Tossal de la Font en la década de 1980 pusieron al descubierto un importante relleno kárstico del Pleistoceno Superior. Entre el registro recuperado destacan, además de diversas especies de herbívoros y carnívoros, así como de un reducido conjunto litotécnico, tres fósiles humanos adscritos en términos generales al grupo de los neandertales. Entre 2004 y 2012, en el marco de un convenio entre la Universitat Jaume I de Castelló (UJI), el Servei d¿Investigacions Arqueològiques i Prehistòriques (SIAP) de la Diputació de Castelló y el Institut Català de Paleoecologia Humana i Evolució Social (IPHES), se ha desarrol…
Assessing the territorial influence of an Iberian worship site. The chemical characterisation of the terracotta from the Iron Age sanctuary of La Ser…
2017
This paper presents the study of the prestigious terracotta votive figurines from the Iberian Iron Age sanctuary of La Serreta (Alicante province, Spain) composed of 174 items. Portable X-ray fluorescence (PXRF) was used to identify elemental markers that permit us to observe the differences between local and non-local terracotta figurines and furthermore to evaluate the geographical influence of the La Serreta sanctuary using Principal Component Analysis (PCA). The Partial Least Squares Discriminant Analysis (PLSDA) statistical method was also used to classify the figurines of uncertain geographical origin. The resulting groups were related to typological and stylistic groups of figurines …
Regional currencies and regional monetary zones in Latin America: what prospects?
2009
Reducing transaction costs and the need for international reserves is a primary objective to the establishment of regional payment agreements. Another objective, especially in the case of Latin America where the Ecuadorian promoters of the Bank of the South (Banco del Sur) and the New Regional Financial Architecture are planning the implementation of a regional clearing system, is to reduce member countries' dependence on the U. S. dollar as an international standard and reserve currency. To help improve the design of such agreements, this paper refers to the plan Keynes designed for the Bretton Woods conference. First, it observes that cases were made against this plan from which useful le…
