A managerial approach to firms’ networking strategy
2009
As recently pointed out by many authors and companies‟ manager, the company competitiveness is more and more based on the ability of a firm to build strategic and competitive networks with partners and competitors. Nowadays, in a competitive environment, firms are facing challenges such as the growing demand of innovation, the increasing competitiveness and the need to penetrate new markets, by using network strategies. Consequently, such motivations are putting an increasing interest on networking strategy issue, which are becoming an essential strength of company competitive strategy. In this work the most significant theories on firm networking are reviewed and an innovative strategic pe…
Apprendenti universitari e profili di competenza nella scrittura accademica
2021
Nell'ambito delle ricerche sulle competenze linguistiche degli studenti universitari in Italia, il contributo indaga le pratiche di comunicazione scritta e le relative difficoltà espresse da studenti di un corso di recupero OFA in corsi di laurea triennale. L'indagine è parte di un progetto di rilevazione più ampio ed è stata realizzata somministrando un questionario informatizzato. I dati raccolti permettono di sviluppare alcune riflessioni utili sul profilo linguistico-comunicativo di apprendenti dalle competenze definite "fragili"; la loro autorappresentazione in termini di biografia linguistica; i bisogni linguistico-comunicativi espressi in rapporto ai compiti di scrittura, e il senso …

Study of optical and magneto processes in Rb atomic vapor layer of nanometric thickness
2012
Using a narrow-band resonant fluorescence spectra from a nano-cell with a thickness of L= [lambda]/2, and VSOP resonances formed at a thickness L =[lambda] ([lambda] is the wavelength of the resonant radiation), for the first time it was experimentally investigated the behaviour of the frequency and intensity (transition probabilities) of the atomic hyperfine structure transitions between the 85Rb, 87Rb, D1 and D2 lines Zeeman sublevels in external magnetic fields in range 5 - 7000G. The behaviour of tens of previously unstudied atomic transitions was analyzed and it is demonstrated that the intensities of these lines can both greatly increase, and decrease (tenfold). For the first time it …
Non-Local Scattering Kernel and the Hydrodynamic Limit
2007
In this paper we study the interaction of a fluid with a wall in the framework of the kinetic theory. We consider the possibility that the fluid molecules can penetrate the wall to be reflected by the inner layers of the wall. This results in a scattering kernel which is a non-local generalization of the classical Maxwell scattering kernel. The proposed scattering kernel satisfies a global mass conservation law and a generalized reciprocity relation. We study the hydrodynamic limit performing a Knudsen layer analysis, and derive a new class of (weakly) nonlocal boundary conditions to be imposed to the Navier-Stokes equations.
Genetic variability in environmental isolates of Legionella pneumophila from Comunidad Valenciana (Spain).
2006
Summary Legionella pneumophila is associated to recurrent outbreaks in several Comunidad Valenciana (Spain) localities, especially in Alcoi, where social and climatic conditions seem to provide an excellent environment for bacterial growth. We have analysed the nucleotide sequences of three loci from 25 environmental isolates from Alcoi and nearby locations sampled over 3 years. The analysis of these isolates has revealed a substan- tial level of genetic variation, with consistent patterns of variability across loci, and comparable to that found in a large, European-wide sampling of clinical isolates. Among the tree loci studied, fliC showed the highest level of nucleotide diversity. The an…
Recombination drives genome evolution in outbreak-related Legionella pneumophila isolates.
2014
Legionella pneumophila is a strictly environmental pathogen and the etiological agent of legionellosis. It is known that non-vertical processes have a major role in the short-term evolution of pathogens, but little is known about the relevance of these and other processes in environmental bacteria. We report the whole-genome sequencing of 69 L. pneumophila strains linked to recurrent outbreaks in a single location (Alcoy, Spain) over 11 years. We found some examples where the genome sequences of isolates of the same sequence type and outbreak did not cluster together and were more closely related to sequences from different outbreaks. Our analyses identify 16 recombination events responsibl…
Selective phenotyping, entropy reduction, and the mastermind game.
2011
Abstract Background With the advance of genome sequencing technologies, phenotyping, rather than genotyping, is becoming the most expensive task when mapping genetic traits. The need for efficient selective phenotyping strategies, i.e. methods to select a subset of genotyped individuals for phenotyping, therefore increases. Current methods have focused either on improving the detection of causative genetic variants or their precise genomic location separately. Results Here we recognize selective phenotyping as a Bayesian model discrimination problem and introduce SPARE (Selective Phenotyping Approach by Reduction of Entropy). Unlike previous methods, SPARE can integrate the information of p…
A Stochastic Model for Population and Well-Being Dynamics
2014
This article presents a stochastic dynamic model to study the demographic evolution per sexes and the corresponding well-being of a general human population. The main model variables are population per sexes and well-being. The considered well-being variable is the Gender-Related Development Index (GDI), a United Nations index. The model's objectives are to improve future well-being and to reach a stable population in a country. The application case consists of adapting, validating, and using the model for Spain in the 2000–2006 period. Some instance strategies have been tested in different scenarios for the 2006–2015 period to meet these objectives by calculating the reliability of the res…
