Item type:Publication, Royal comestabuli and Military Control in the Sicilian Kingdom: A Prosopographical Contribution to the Study of Italo-Norman AristocracyWhen the Sicilian monarchy was established after years of conflict, King Roger II began to consolidate his authority on the Italian peninsula. The establishment of titles for the organization and control of the continental provinces has been noted by several scholars as an instrumental feature of the kingdom's social arrangement. Yet, contemporary scholarship has dismissed the royal comestabuli as unimportant social agents, either as "officials" documented in the Catalogus Baronum or as territorial lords. As a result, several questions surrounding the issue remain unanswered: to what extent did the local, lesser aristocracy shape the kingdom's effective social, and military, control over Southern Italy, and who were the nodal characters that allow us to discern this process? Was a comestabulia a fixed administrative district, or rather a type of social authority? Although in this limited space a finished picture cannot be presented, this article offers the results of a recent prosopographical exploration of South Italian sources for the Norman period. By taking the comestabuli as a starting point, I study the intermediary position that particular barons held as both royal agents and para-comital supervisors of the military contingents levied from the kingdom's aristocracy. This article attempts not only to shed some light on this almost ignored class of functionaries, but also to further explore the social roles established amongst the Italo-Norman nobility. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Political Manoeuvring in the Norman Kingdom of Sicily: Civitate and Carinola in the Development of the South-Italian CountyOne the of most interesting documents concerning the social and political history of the Norman Kingdom of Sicily can be found in the first instance in Giuseppe Del Giudice’s appendix to his diplomatic collection of Angevin documents. The document records Robert, Count of Civitate, restoring some lands that Robert Guiscard and Roger II had formerly granted to Abbot Unfredus of Terra Maggiore, and agreeing upon some exemptions and privileges. The edited document, though seemingly unimportant and relevant only at a local level, is not only crucial for the understanding of King Roger’s rearrangement of the nobility and their dominions in the mainland. What I argue here is that it also exemplifies the contemporary usage of the notion of county as a construction of something more than just a ‘countship,’ and rather a cluster of lordships defined by the social role exercised by the Norman count. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, What can we learn from the Semantic Web to ‘revamp’ our Historical Research?This article comes as a result of the self-learning process I went through to understand what linked data is and how to use the semantic web model for collecting and organising my own historical data. In order to share this experience with a wider, non-specialised audience, I have written an introduction to the fundamental concepts behind the semantic model, accompanied by some brief reflections on their conceptual implications and examples on how to apply them to socio-historical data. In so doing, I wrote the introductory reflection that I wished I had known when I first heard the semantic web. The review of key concepts offers definitions for relational and linked data, graph database, RDF, semantic triple, vocabulary, ontology, and OWL. It is however a basic introduction, and it does not pretend to serve as a new contribution to the field or as a tutorial for learning how use RDF or OWL. Instead, it offers a beginner’s guide for students and researchers alike; it aims to show the reader where to start and what to expect. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The Making of Medieval SardiniaVolume Editors: Alex Metcalfe, Hervin Fernández-Aceves, and Marco Muresu. This landmark volume combines classic and revisionist essays to explore the historiography of Sardinia’s exceptional transition from an island of the Byzantine empire to the rise of its own autonomous rulers, the iudikes, by the 1000s. In addition to Sardinia’s contacts with the Byzantines, Muslim North Africa and Spain, Lombard Italy, Genoa, Pisa, and the papacy, recent and older evidence is analysed through Latin, Greek and Arabic sources, vernacular charters and cartularies, the testimony of coinage, seals, onomastics and epigraphy as well as the Sardinia’s early medieval churches, arts, architecture and archaeology. The result is an important new critique of state formation at the margins of Byzantium, Islam, and the Latin West with the creation of lasting cultural, political and linguistic frontiers in the western Mediterranean. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Oikía y Polis. La familia, raíz y alma de toda sociedadToda sociedad, ya sea grande o pequeña, de un estilo y otro, puede existir de verdad y aspirar a perpetuarse en la existencia trascender en la medida que logre desarrollar un auténtico humus familiar en el que se pueda enraizar. En éste se aspira la vida, consolidándose como el alma primera que faculta para ser verdaderamente social y generar sociedad de modo verdadero. Por consiguiente, no se puede afirmar que lo social y la sociedad en general existen primeramente, y la familia es una manifestación más, entre otras, de lo social que incluso puede cambiar de forma o tornarse irrelevante. Por el contrario como se afirma en la presente obra no se puede tener una sociedad verdadera si ésta no tiene raíces y alma familiares.14 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Transhumanismo bioprogresista extropianista, posthumanismo y bioconservadurismo a la luz del concepto de naturaleza de santo Tomás de Aquino(2021)Aunque el auge del transhumanismo progresista extropianista que apunta a un posthumanismo se ha desarrollado en las últimas tres décadas, es fácil ver que se trata de un asunto del pasado, del presente y del futuro. Es un hecho que desde que el hombre empezó a intervenir en la naturaleza ha superado muchas fronteras impuestas por su precariedad. Ya Aristóteles se había referido al hombre como homo faber. No obstante, frente a los avances tecnológicos, últimamente ha surgido una respuesta a las propuestas de los transhumanistas por parte de los que se han llamado bioconservaduristas. Ambos puntos de vista coinciden en que no todo lo que se puede llamar “mejoras” al ser humano, tiene el mismo estatuto ontológico y moral. También resulta interesante ver si es posible que el transhumanismo llegue a un extropianismo o a un posthumanismo, lo cual conduce el discurso científico a un plano filosófico. El propósito de este trabajo es descubrir los alcances y los límites ontológicos de este movimiento, a partir del concepto de naturaleza desarrollado por santo Tomás de Aquino, cuya propuesta es clásica y perenne. Veremos cómo el concepto de naturaleza en santo Tomás nos arroja luz para responder las interrogantes que últimamente se han planteado los intelectuales de este movimiento filosófico, científico y cultural.23 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Value at risk estimation in the Mexican Stock Exchange: A comparison or empirical distributions(2019)Ramona Serrano BautistaThe objective of this paper is to address the issue of VaR model selection for the Mexican equity market. To this end, we consider the family of stable distributions in VaR modeling as an alternative in the Mexican financial market and its performance is compared with the normal, NIG, GLD and GST estimations. We directed a statistical analysis to compare the suitability of these five distributions on the equity stock returns during a period of high volatility. The approaches are based on the maximum likelihood estimation of the parameters of a distribution. The estimation of the conditional variance of returns is based on the GARGH model with the innovation of α-stable, GST, GLD and NIG distributions to describe returns. In addition, the predictive power of the heteroscedasticity in VaR models is tested using the so called back testing and the Kupiec likelihood ratio test. The statistical results showed evidence that the α-stable model provides superior fit in modeling VaR at high confidence levels. In contrast, stable modeling is not satisfactory at low confidence level.7 - Some of the metrics are blocked by yourconsent settings
