Frustration of structural fluctuations upon equilibration of shear melts
2002
Abstract We report on the formation of amorphous solids from aquaeous suspensions of charged colloidal spheres. Comprehensive light scattering and microscopic studies show that in these systems the nucleation rate density continuously increases to very high values. At the highest particle densities of 47.5 μm −3 (packing fraction Φ =0.146) an amorphous state is observed of only short range order, finite static shear modulus and frozen long time dynamics. This state is composed of a piling of––as we propose pre-critical––nuclei. Differences from the Hard Sphere case are discussed in some detail. There the arrest of density fluctuations is observed and described by Mode Coupling scenarios. In…
Winning the hearts and minds of followers: The interactive effects of followers' emotional competencies and goal setting types on trust in leadership
2015
La confianza de los seguidores es un elemento esencial de un liderazgo eficaz. Las aproximaciones tempranas a la formación de la confianza hacia los líderes, adoptaron un enfoque basado en evaluaciones basadas en información. Sin embargo, avances recientes en la investigación de la confianza sugiere que estas evaluaciones también contienen un componente afectivo. En este estudio proponemos que las competencias emocionales, como (1) atención, (2) claridad y (3) reparación emocional predecirán la confianza hacia el líder en momentos tempranos de la relación líder-seguidor. A medida que esta relación se desarrolla en el tiempo, las evaluaciones sobre la fiabilidad del líder cambiaran su objeti…
Análisis de los factores determinantes de la lealtad hacia los servicios bancarios online
2011
ResumenEl rápido crecimiento de la banca online refleja las ventajas que ésta ofrece respecto a las sucursales convencionales. No obstante, son muchos los consumidores que todavía utilizan los servicios bancarios online de forma esporádica, fundamentalmente para la comprobación de saldos, evitando realizar transacciones con un mayor nivel de riesgo. El objetivo de este estudio es analizar los factores determinantes de la lealtad hacia los servicios bancarios online, a través de un modelo integrador de la influencia del riesgo percibido y la confianza en las webs bancarias con el marco conceptual de la Teoría del Comportamiento Planificado (TCP). La configuración del riesgo percibido se ha p…
El papel de la confianza, la imagen y los valores compartidos en la creación de valor y lealtad: aplicación a la relación egresado-universidad
2014
ResumenEl presente estudio plantea una aplicación del marketing de relaciones en el ámbito de la educación superior, específicamente la relación egresado-universidad. El modelo propuesto aporta variables poco estudiadas en este ámbito y tiene como objetivo estudiar el papel de la confianza en la relación egresado-universidad, sus posibles antecedentes y sus consecuencias. Los resultados muestran cómo la imagen de la universidad, la satisfacción y los valores compartidos de los egresados influyen positivamente en la confianza, la cual, a su vez, afecta al valor percibido y a los niveles de lealtad. Las conclusiones e implicaciones aportan conocimientos innovadores con relación al mantenimien…
How Terrorism Changed the Ways of Interpreting Hospitality
2017
The consolidation of Thana-Capitalism doubtless affected the tourism industry, but also changed the ways in which the Other is conceived. Needless to say, anthropology should play a leading role in providing new theories to understand ‘cosmopolitanism’, and the position of this global dangerous Other in Europe. Discussing and engaging directly with Derrida as well as other scholars, this chapter focuses on how hospitality is dying. The end of hospitality represents a serious challenge of Europe simply because it was ‘the alma matter’ of its rationality and social trust. At times, terrorism targets ‘the exemplary centre of consumption’ to extortionate the developed nation-states, the surveil…
Nuova introduzione al diritto inglese
2021
Il passaggio del tempo è già di per sé una ragione sufficiente per consigliare l’aggiornamento di un’opera attraverso la pubblicazione di una sua nuova edizione che contempli anche solo informazioni ed opinioni sopravvenute relative alla materia trattata. Il quinquennio trascorso da quando vide la luce la “Nuova introduzione allo studio del diritto inglese”, prosecuzione ideale e tematica dell’originaria fatica di Giovanni Criscuoli all’inizio del XXI secolo non è, tuttavia, la sola circostanza che mi ha indotto a curare e ad assumere la gravosa responsabilità della rinnovata edizione, sempre avvalendomi dell’indicazione con un asterisco delle parti da me direttamente redatte. Essa si è res…

Consumer protection from greenwashing
2023
The purpose of this paper is to offer some reflection on the importance of reliable green claims to encourage sustainable production. The role of market is fundamental. Businesses and consumers are both involved in achieving environmental protection objectives. There is the real risk of the phenomenon of so-called green washing or misleading marketing. The problem arises of verifying the reliability of green claims to prevent competitive elements from become distorting factors of competition.
Generation of Earth's early continents from a relatively cool Archean mantle
2019
This research has been supported by DFG grant, SPP 1833 Building a Habitable Earth and MAGMA Consolidator Grant (ERC project #71143). Several lines of evidence suggest that the Archean (4.0 2.5 Ga) mantle was hotter than today's potential temperature (TP) of 1350 ° C. However, the magnitude of such difference is poorly constrained, with TP estimation spanning from 1500 ° C to 1600 ° C during the Meso‐Archean (3.2‐2.8 Ga). Such differences have major implications for the interpreted mechanisms of continental crust generation on the early Earth, as their efficacy is highly sensitive to the TP. Here, we integrate petrological modeling with thermomechanical simulations to understand the dynami…
Active geodynamics of the central Mediterranean Sea: Tensional tectonic evidences in western Sicily from mantle-derived helium
2005
[1] We report results on the measured high 3He/4He isotope ratio in western Sicily, interpreted together with the heat data. The study of this sector of the Europe-Africa interaction is crucial to a better understanding of the tectonics and the geodynamical evolution of the central Mediterranean area. The estimated mantle-derived helium fluxes in the investigated areas are up to 2–3 orders of magnitude greater than those of a stable continental area. The highest flux, found in the southernmost area near the Sicily Channel, where recent eruptions of the Ferdinandea Island occurred 20 miles out to sea off Sciacca, has been associated with a clear excess of heat flow. Our results indicate that…
