The behaviour of non consumer of organic food: suggestions on marketing strategies to attract new market segments
2013
Oggi le produzioni agricole biologiche sono in netta crescita sia a livello internazionale che nazionale. Tra le regioni italiane la Sicilia rappresenta la principale area di produzione e si colloca all’ultimo posto relativamente ai consumi. Attraverso un’indagine pilota nella citta di Palermo, si e voluto indagare, sui motivi del mancato acquisto di prodotti biologici per comprendere quali sono le leve del marketing mix su cui e possibile intervenire per attrarre nuovi segmenti di mercato. L’indagine e stata realizzata intervistando un campione di non-consumatori di alimenti biologi presso alcuni supermercati della citta. I campioni, degli intervistati e dei supermercati, sono stati selezi…
La circulation des objets métalliques à l'âge du Bronze entre Rhône et Saône: utilisation d'une transformation cartographique linéaire
2006
In order to gain a better understanding of circulation flows of metal objects during the Bronze Age, and move beyond traditional distribution maps of archaeological discoveries, the authors propose a more quantitative and concise method of graphic representation, namely cartographic linear transformation. The value of the method was tested on the Saône-Rhône axis. Bronze axes, swords and daggers were recorded along a 50 km strip either side of the river axis, in order to estimate the frequency and mass of objects in “circulation”.
Cartographie des restes osseux et conservation différentielle dans l'amas coquillier d'Ouessant "Mez Notariou": du Bronze moyen à la période romaine
2008
This article addresses the impacts of differential preservation in an alkaline shell midden (fig. 1) overlying an acid soil which does not allow bone to survive. This midden accumulated over an extended period and displays unusual traits attributable to practices of a ritual nature (Le Bihan et Méniel, 2002). Excavation extended to approximately 1000 square metres (fig. 2). Bone was collected on a quarter-metre grid by individual context (fig. 3). Some 35,000 animal and bird bones were recovered; fish bones, which were very numerous, are presently still under study. Consideration of the entire bone assemblage (fig. 8) indicates that the principal deposition occurred along the SW/NE axis of …
Search for Gravitational-wave Signals Associated with Gamma-Ray Bursts during the Second Observing Run of Advanced LIGO and Advanced Virgo
2019
We present the results of targeted searches for gravitational-wave transients associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo, which took place from 2016 November to 2017 August. We have analyzed 98 gamma-ray bursts using an unmodeled search method that searches for generic transient gravitational waves and 42 with a modeled search method that targets compact-binary mergers as progenitors of short gamma-ray bursts. Both methods clearly detect the previously reported binary merger signal GW170817, with p-values of <9.38 10-6 (modeled) and 3.1 10-4 (unmodeled). We do not find any significant evidence for gravitational-wave signals associate…
Urban 3-D models for plannig of mobile telephony systems
2000
This paper deals with an application of numerical cartography, carried out by means of digital photogrammetry techniques, aimed at the planning of mobile telephony cells. Particularly, urban 3-D vector models (wireframe), got by digital restitution and integrated by raster images referred to rectified buildings facades, were carried out in a sample area selected inside the Orleans Park, seat of the Palermo University. Then such models were processed by computer graphics techniques owing to the operations of rendering and animation. These 3-D representations could come in very useful for study and planning of mobile telephony networks in urban areas.
Revisiting Bicausative Matrices: The Swiss Cheese of Chaos
2009
This paper returns to de Mesnard's paper of 2000, which has exposed the so-called method of bicausative matrices. This method was created to analyze the structural change between two matrices, as an improvement of the causative method of Jackson and al. (1990). In its 2000 paper, de Mesnard has shown that chaos affects the bicausative method: two solutions are found with a brutal switching between both. This new paper demonstrates that the chaos can be largely circumvented, is essentially localized in a small interval and is only a transitory effect between two non-chaotic "regimes", is not always observed, is limited to relatively small matrices.
Charged particle multiplicity distributions in restricted rapidity intervals in Z0 hadronic decays.
1991
The multiplicity distributions of charged particles in restricted rapidity intervals in Z0 hadronic decays measured by the DELPHI detector are presented. The data reveal a shoulder structure, best visible for intervals of intermediate size, i.e. for rapidity limits around ±1.5. The whole set of distributions including the shoulder structure is reproduced by the Lund Parton Shower model. The structure is found to be due to important contributions from 3-and 4-jet events with a hard gluon jet. A different model, based on the concept of independently produced groups of particles, "clans", fluctuating both in number per event and particle content per clan, has also been used to analyse the pres…
UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
Nucleon structure functions and light front dynamics
1999
We present a quark-parton model to describe polarized and unpolarized nucleon structure functions. The twist-two matrix elements for the QCD evolution analysis of lepton-hadron scattering are calculated within a light-front covariant quark model. The relativistic effects in the three-body wave function are discussed for both the polarized and unpolarized cases. Predictions are given for the polarized gluon distributions as will be seen in future experiments.
Atlas Lingüístico de la Península Ibérica (ALPI): Estudi i edició del País Valencià
2001
La tesi doctoral “Atlas Lingüístico de la Península Ibérica (ALPI): Estudi i edició del País Valencià” pretén recuperar un material lingüístic (fonètic, morfosintàctic i lèxic) inèdit recollit al País Valencià entre 1934 (pobles castellanoparlants) i 1935 (pobles valencianoparlants) per investigadors de la talla de M. Sanchis Guarner i F. de B. Moll. La recuperació d’aquest material està feta de forma digital, escrita (edició de les enquestes) i il·lustrada per mapes lingüístics (cartografia selectiva). Es tracta d’unes enquestes lingüístiques projectades pel Centre d’Estudis Històrics de Madrid (precedent de l’actual CSIC), presidit per R. Menéndez Pidal, qui va encarregar el projecte al m…
