Especificaciones alternativas de la estructura temporal de volatilidades
2005
En este trabajo se describe y analiza la estructura temporal de volatilidades instantáneas de los tipos de interés forward correspondientes al mercado español durante el periodo 1999-2002. Este estudio se realiza en el contexto del Modelo de Mercado LIBOR proponiéndose, además, una nueva fórmula para describir la volatilidad instantánea de los tipos de interés forward con parámetros fácilmente interpretables. Junto a este modelo se calibran otros dos alternativos propuestos en la literatura que son utilizados como benchmark para contrastar su validez. Esta contrastación se lleva a cabo a partir de datos del mercado de caps proporcionando resultados satisfactorios para el modelo aquí present…
«Hinc Tomyris Crassum male multat»: nota a Naldo Naldi, carm. var. VI 121-138
2020
In questa nota viene proposta l’analisi di un breve episodio che si legge nel carme ‹De virtute› (carm. var. 6, 121-138) del poeta fiorentino Naldo Naldi (1439-1513), relativo alla figura di Marco Licinio Crasso, fin dall’antichità e, poi, nel Medioevo e nell’Umanesimo, tipico exemplum di insaziabile avidità e di avarizia punita. This note proposes the analysis of a short episode that can be read in the poem ‹De virtute› (carm. var. 6, 121-138) of the Florentine poet Naldo Naldi (1439-1513), relating to the figure of Marco Licinio Crasso, since Antiquity and then, in the Middle Ages and Humanism, a typical exemplum of insatiable greed and punished avarice.
Análisis del comportamiento espacio-temporal intradestino mediante GPS : Una aproximación de los visitantes independientes de crucero en la ciudad de…
2020
El presente trabajo tiene como objetivo profundizar en el análisis de los patrones de comportamiento espacio-temporal de los visitantes en destino, una escala de trabajo insuficientemente desarrollada. La investigación aplica un enfoque multimétodo, que combina el uso de GPS con una encuesta, al conocimiento de los patrones espaciales de los cruceristas que visitan la ciudad de Valencia de manera independiente. Los resultados obtenidos evidencian la polarización de los flujos en el centro histórico de la ciudad, dentro de un patrón mayoritario de único nodo, una dinámica que conviene gestionar adecuadamente para prevenir la congestión y poner en valor otros atractivos urbanos. La redistribu…
Fuzzy Multi-Criteria Decision Making: An entropy-based approach to assess tourism sustainability
2019
In this article, we propose a method for ranking tourist destinations and evaluating their performances under a sustainability perspective: a fuzzy multiple criteria decision-making method is applied for determining sustainability performance values and ranking destinations accordingly. We select a set of sustainability evaluation criteria and use a fuzzy analytic hierarchy process to weight the selected criteria. We also optimize each evaluator’s membership function support by means of a fuzzy entropy maximization criteria. A case study is illustrated and results are compared with two data envelopment analysis–based models. The simplicity of the proposed approach along with the easy reada…
A fuzzy evaluation of tourism sustainability
2019
For many years the sustainability assessment of tourist destinations has been based on the carrying capacity, which is a measure that takes into account the preservation of a geographical area (by measuring the number of tourists, the visitor flow and the environmental thresholds) along with its tourist fruition (by assessing the quality of the experience perceived by visitors). Unfortunately, its definition lacks clarity, and its dependence upon qualitative variables makes it unable to provide a unique criterion for its assessment. In this paper we propose a fuzzy approach that takes into account the inherent uncertainty and vagueness of the involved variables to assess a destination’s sus…
The role of ICT, eWOM and guest characteristics in loyalty
2019
Purpose This study aims to examine how technologies contribute to consumer loyalty in the tourist industry. To achieve this objective, information and communication technology (ICT) development and electronic word-of-mouth (eWOM) are analysed to explore their direct and indirect effects on satisfaction and loyalty dimensions. The moderating role of customer characteristics (personal and experience-related variables) is also considered to study the complex relationship between satisfaction and loyalty. Design/methodology/approach A quantitative study based on a questionnaire structured was developed. The survey was conducted with 386 guests from Spanish hotels. SEM methodology is applied to…
Fazioni e popolo in una provincia del dominio pontificio fra XIII e XIV secolo
2021
Between the 13th and 14th centuries, a number of cities in the inchoative papal state experimented a system of self-government that allowed the Guelph and Ghibelline factions, formally represented in those same bodies on an equal footing, to work alongside the more strictly communal magistracies. The case of Todi is rather well known, given the role that Bartolo da Sassoferrato assigns to it in his Tractatus de guelphis et gebellinis (ca. 1350), but current research has already ascertained that this political tradition appeared at least around 1260. Some evidence can suggest, however, that some form of integration of factions into the local institutional framework was possible elsewhere, an…
Risk exposure to vibration and noise in the use of agricultural track-laying tractors.
2016
Human exposure to mechanical vibration may represent a significant risk factor for exposed workers in the agricultural sector. Also, noise in agriculture is one of the risk factors to be taken into account in the evaluation of workers’ health and safety. One of the major sources of discomfort for the workers operating a tractors is the noise to which they are exposed during work. The aim of this study was to evaluate the risk of exposure to whole-body vibration for the operator driving track-laying tractors in vineyard orchard and the noise level. The experimental tests were performed with six different track-laying tractors coupled with the same rototilling machine. The results showed that…
Turkish women writers in English translation
2011
The present paper aims to present a brief survey of Turkish women writers in English translation. Due to the dominant position of English, Turkey has been rather dependent on translations from this language and the flow of translations into the opposite direction has been quite slow. Yet, there is a considerable increase in the number of translations from Turkish into English especially since the 1980s. This also holds true for the works of women writers, and, of women’s fiction in particular, which is closely related to the bond between writing and women’s increased consciousness. The paper also briefly touches upon issues such as what has not been translated and why, and the role translat…
Marcadores inmunológicos de protección frente al citomegalovirus en el trasplante alogénico de precursores hematopoyéticos
2015
En la actualidad, la mayoría de centros emplean la estrategia del tratamiento antiviral anticipado guiado por PCR en tiempo real (monitorización virológica) para prevenir el desarrollo de enfermedad orgánica en el alo-TPH. Esta estrategia es muy eficaz, pero tiene como efecto indeseado la toxicidad asociada al sobretramiento de los pacientes, de modo que es potencialmente mejorable. En este sentido, la presente tesis doctoral aporta información sobre las cinéticas de la DNAemia viral en el compartimento sistémico, como una herramienta útil en el manejo de la infección activa por el CMV . Por otra parte, tras el trasplante, es de vital importancia la reconstitución funcional de los linfocito…
