Conceptualization and Examination of Success Factors in the Banking System
2016
Abstract Banking competition has intensified in recent years, largely due to globalization, technological process and economic instability. The banking system in this context is supplied with considerable challenges, with customers’ characteristics, needs and desires consistent with the current environment (globalization, technological change and economic crisis). It is necessary to identify those features that contribute to the development of competitive advantage. In this sense, this paper shows the results of the analysis of success factors in the banking system. To obtain the results the following methods were used: in-depth questionnaire (for experts), questionnaire (for customers), ob…
La lettre galante et l'esprit géométrique : expression métaphysique et métaphysique des langues, ou la philosophie du discours de Fontenelle
2015
International audience; Il n'est paradoxal qu'en apparence d'affirmer que Fontenelle est un philosophe pour qui la question du style ne se pose pas. Pour le dire simplement, Fontenelle est pour une large part étranger à l'idée que la philosophie puisse constituer un corpus distinct d'objets et de thèses à propos duquel se poserait spécifiquement la question de son écriture ou de son expression. Fontenelle ne pose pas tant la question de savoir comment il convient d'écrire la philosophie, ni telle philosophie, y compris la sienne propre, qu'il ne défend par sa pratique scripturaire l'idée d'une écriture ou d'une récriture philosophique de tout ce qui s'écrit : oeuvres drama-tiques, lettres g…
Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…
2019
Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…
Il concorso per il Rione Villarosa
2018
Negli anni del dopoguerra, l’interesse per le città crebbe. I concorsi di piano regolatore divengono mezzi per attuare questa trasformazione, in cui generatori sono le provvidenze amministrative e le combinazioni finanziarie. Anche a Palermo si tentò di diffondere una consapevolezza urbanistica, che si manifesta nella competizione per il Piano Regolatore di Palermo del 1939, e una serie di competizioni tra cui quella del Rione Villarosa. L’annuncio prevedeva infatti la creazione di una vera “città”, di fatto estranea alla natura del luogo. Tra i quindici progetti presentati, il bozzetto con lo pseudonimo “V. R. 112” formato da Aldo Della Rocca, Ignazio Guidi, Enrico Lenti e Giulio Sterbini …
Structure and transport properties of amorphous aluminium silicates: computer simulation studies
2005
The structure and transport properties of SiO2-Al2O3 melts containing 13 mol% and 47 mol% Al2O3 are investigated by means of large scale molecular dynamics computer simulations. The interactions between the atoms are modelled by a pair potential which is a modified version of the one proposed by Kramer et al. [J. Am. Chem. Soc. 64, 6435 (1991)]. Fully equilibrated melts in the temperature range 6000 K >= T > 2000 K are considered as well as glass configurations, that were obtained by a rapid quench from the lowest melt temperatures. Each system is simulated at two different densities in order to study the effect of pressure on structural and dynamic properties. We find that the Al ato…
X-ray versus Ultraviolet Irradiation of Astrophysical Ice Analogs Leading to Formation of Complex Organic Molecules
2019
In astrochemistry, complex organic molecules (COMs) are defined as species with at least one C atom and six or more atoms in total. More than 70 COMs were detected toward various interstellar and c...
Direct measurement of forces between particles and bubbles
1999
One of the elementary stages of the flotation process is the formation of an aggregate between the particle and a bubble. This aggregate formation is governed by hydrodynamic, capillary and interparticle forces. During the last four years, techniques have been developed to measure directly the force between a colloidal particle and a bubble. These techniques are closely related to the development of atomic force microscopy. Advantages and possibilities, as well as limits and drawbacks are described.

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…
Small-angle neutron scattering reveals an oxygen-dependent conformational change of the immunogen keyhole limpet hemocyanin type 1 (KLH1).
2001
The respiratory protein of the keyhole limpet, Megathura crenulata, the hemocyanin (KLH), commonly used as an immunogen, binds oxygen cooperatively, which implies the existence of different conformations. For the first time, two different conformations of KLH1 were detected upon oxygenation, a deoxy and an oxy state, using small-angle neutron scattering. Rearrangements in the quaternary structure of KLH1 were predicted from the different radii of gyration and the shifts of the minima and maxima in the scattering curves. Upon oxygenation, KLH1 becomes smaller and more compact. Model reconstruction of KLH1 indicates a hollow cylinder with two rings located close to both ends, which move sligh…
