Two main points are made. First, the postulates of Revealed Preference Theory are sufficient but not necessary to give empirical content to Utility Theory. Empirically testable implications can be obtained under alternative assumptions about individuals’ preferences which allow for social determinants of behavior. Second, the observation of individuals’ behaviour may not be sufficient to obtain the information about people’s preferences which is required to study welfare. There are cases where the information about preferences obtained from observed behaviour has to be integrated with information obtained from survey data because of externalities which affect utility but have no behavioural implication.Ennio Bilanciniennio.bilancini@imtlucca.it2016-03-09T08:59:42Z2016-09-14T10:21:18Zhttp://eprints.imtlucca.it/id/eprint/3205This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/32052016-03-09T08:59:42ZL'attività normativa del governo nel periodo maggio-novembre 2006Martina ConticelliLorenzo Casinilorenzo.casini@imtlucca.it2016-03-08T13:53:22Z2016-09-14T10:21:17Zhttp://eprints.imtlucca.it/id/eprint/3204This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/32042016-03-08T13:53:22ZL'attività normativa del governo nel periodo dicembre 2006-maggio 2007Martina ConticelliLorenzo Casinilorenzo.casini@imtlucca.it2016-03-02T11:24:31Z2016-09-14T10:21:17Zhttp://eprints.imtlucca.it/id/eprint/3172This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/31722016-03-02T11:24:31ZL'organizzazioneLorenzo Casinilorenzo.casini@imtlucca.itEdoardo Chiti2016-01-14T08:40:21Z2016-09-14T10:21:17Zhttp://eprints.imtlucca.it/id/eprint/3000This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/30002016-01-14T08:40:21ZArchivi e biblioteche: memorie del passato dall'incerto futuroLorenzo Casinilorenzo.casini@imtlucca.it2016-01-14T08:38:27Z2016-09-14T10:21:17Zhttp://eprints.imtlucca.it/id/eprint/2999This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/29992016-01-14T08:38:27ZL'inchiesta pubblica.

This spectrometer can operate in specific modes to match decay scheme of a particular radionuclide and is specially suited for measurement of positron emitters. The system consists of a hyperpure Ge detector (3 kg, 147 relative efficiency), operating in coincidence with an umbrella of NaI(Tl) scintillator (90 kg) in order to achieve low background. The system is tuned such that strong interference due to naturally occurring uranium daughters, e.g. 214Bi present in the meteorites and in the laboratory environment, is minimized. It enables us to measure 44Ti ( T 1 / 2 = 59.2 y ) which is ideal for studying centennial scale variations of cosmic ray flux in the interplanetary space with good reliability. The specific configuration of the coincidence system and electronics are described here.

The solar magnetic activity modulates the galactic cosmic ray flux, which is responsible for producing radioactive nuclides in rocks on planetary surfaces and in meteorites. To measure the minute quantity of γ emitting cosmogenic radionuclides, we have set up a low background, highly specific and selective γ-ray spectrometer. Using this spectrometer, we have reconstructed the solar activity over the past 3 centuries by measuring 44Ti and 26Al in meteorite falls; in particular we have shown that the intensity of cosmic rays has linearly decreased, in agreement with some models proposed for the past solar activity. In order to improve the Ge-NaI coincidence spectrometer, crucial for selective 44Ti detection, we have developed a multiparametric acquisition system. The flexibility of optimizing appropriate energy channels allows more reliable measurement of the small activity present in meteorites.Carla TariccoPaolo ColombettiNeeharika VermaGianna Vivaldogianna.vivaldo@imtlucca.itNarendra Bhandari2014-07-03T12:17:44Z2016-04-06T09:47:39Zhttp://eprints.imtlucca.it/id/eprint/2242This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/22422014-07-03T12:17:44ZLa spesa farmaceutica territoriale convenzionata: il modello FarmaRegio per l'analisi della variabilità regionaleSi presenta la prima versione di FarmaRegio, modello econometrico per l'analisi della variabilità regionale della spesa farmaceutica territoriale convenzionata (un panel ad effetti casuali). Si suggeriscono due prospettive di lettura: da un lato, la valutazione della significatività delle variabili esplicative; dall'altro, l'interpretazione della relazione funzionale stimata come possibile benchmark con cui chiedere alle Regioni di confrontarsi. Nel primo caso, emergono chiare indicazioni di policy: la rilevanza del reddito e quindi dei flussi di perequazione a sostegno dei LEA, ma anche l'importanza degli strumenti di regolazione lato offerta/domanda, e delle riforme pro concorrenziali della distribuzione al dettaglio. Poco significativo appare l'impatto dell'invecchiamento, la qual cosa dovrebbe far riflettere sul peso da assegnare a questa variabile nell'allocazione interregionale delle risorse oppure, nel caso in cui il risultato derivasse da razionamenti dell'offerta, sull'utilità di ripristinare vincoli di destinazione mirati su una selezione di prestazioni. Nel secondo caso, la relazione funzionale media può concorrere a dare concretezza a quel riferimento ai costi standard dei LEA presente anche nel recente disegno di legge applicativo dell'articolo 119 della Costituzione.Chiara BonassiLaura MagazziniFabio Pammollif.pammolli@imtlucca.itMassimo Riccabonimassimo.riccaboni@imtlucca.itNicola C.

In this case, a contribution is offered in construction of two groups of indicators: travel cost and gravity based indexes. A case study is proposed on the level of accessibility of two towns of commuters in the island of Sardinia, Italy.Andrea De MontisSimone CaschiliMichele CampagnaAlessandro Chessaalessandro.chessa@imtlucca.itGiancarlo Deplano2013-11-07T11:03:39Z2013-11-20T09:08:17Zhttp://eprints.imtlucca.it/id/eprint/1883This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/18832013-11-07T11:03:39ZThe structure of interurban traffic: a weighted network analysisWe study the structure of the network representing the interurban commuting traffic of the Sardinia region, Italy, which amounts to 375 municipalities and 1 600 000 inhabitants. We use a weighted network representation in which vertices correspond to towns and the edges correspond to the actual commuting flows among those towns. We characterize quantitatively both the topological and weighted properties of the resulting network. Interestingly, the statistical properties of the commuting traffic exhibit complex features and nontrivial relations with the underlying topology. We characterize quantitatively the traffic backbone among large cities and we give evidence for a very high heterogeneity of the commuter flows around large cities. We also discuss the interplay between the topological and dynamical properties of the network as well as their relation with sociodemographic variables such as population and monthly income. This analysis may be useful at various stages in environmental planning and provides analytical tools for a wide spectrum of applications ranging from impact evaluation to decision making and planning support.

New research perspectives have been opened in the study of many real phenomena and processes, and recently fields like urban, regional, and environmental sciences have gained new insights from the tools provided
by Network Science. The complex networks analysis becomes a useful framework in these fields to disentangle problems of a complex and unpredictable nature.
This paper presents a research agenda on a number of operative tools borrowed from complex network analysis for regional studies: the comparative analysis of commuting systems, the investigation on the influence of spatial properties on complex networks, the detection of
communities in commuting systems and the integration between network analysis and geographical information systems.Andrea De MontisAlessandro Chessaalessandro.chessa@imtlucca.itMichele CampagnaSimone CaschiliGiancarlo Deplano2013-11-06T16:01:22Z2014-09-02T09:48:04Zhttp://eprints.imtlucca.it/id/eprint/1880This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/18802013-11-06T16:01:22ZGrouping complex systems: a weighted network comparative analysisIn this study, the authors compare two inter-municipal commuting networks (MCN) pertaining to the Italian islands of Sardinia and Sicily, by approaching their characterization through a weighted network analysis. They develop on
the results obtained for the MCN of Sardinia (De Montis et al. 2007) and attempt to use network analysis as a mean of detection of similarities or dissimilarities between the systems at hand.Andrea De MontisAlessandro Chessaalessandro.chessa@imtlucca.itMichele CampagnaSimone CaschiliGiancarlo Deplano2013-11-06T15:47:22Z2013-11-06T15:47:22Zhttp://eprints.imtlucca.it/id/eprint/1879This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/18792013-11-06T15:47:22ZModeling commuters dynamics as complex network: the influence of the spaceThis study extends previous works developed by the authors analysing the interplay between the dynamics and the economics of the real network underlying the
regional intermunicipal commuting system of Sardinia, Italy. Further insights have been earned into the influence of the network spatial properties, by means of network
modeling in GIS environment, which takes into account the intermunicipal distance features of the corresponding physical transport network. The authors discuss how modelling complex networks in a GIS environment may be
considered an innovative approach in the field, as it allows to better think spatially about complex network models. In this perspective, they outlook a a working
framework on the possible integration settings between GIS and complex networks models.Michele CampagnaSimone CaschiliAlessandro Chessaalessandro.chessa@imtlucca.itAndrea De MontisGiancarlo Deplano2013-11-06T14:46:17Z2013-11-07T11:20:32Zhttp://eprints.imtlucca.it/id/eprint/1878This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/18782013-11-06T14:46:17ZInspecting the influence of space on a real complex networkThe paradigm of complex network provides the analysts with the opportunity to model real systems by invoking the interaction properties between elements and their topology. Recently, many scholars have applied network analysis when studying socio-economic processes in urban, regional, and environmental planning. Within this realms, complex
network theory can be interpreted as an innovative analytical framework for analysing and planning systems characterised by uncertainty and unpredictability.
After this introductory remarks, the aim of this paper is to present and comment results obtained by applying complex network analysis to the characterization of topological, traffic and spatial properties of commuters’ systems of insular Italy.Michele CampagnaSimone CaschiliAlessandro Chessaalessandro.chessa@imtlucca.itAndrea De MontisGiancarlo Deplano2013-10-03T13:31:30Z2016-04-06T10:05:02Zhttp://eprints.imtlucca.it/id/eprint/1814This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/18142013-10-03T13:31:30ZStretching HomopolymersForce-induced stretching of polymers is important in a variety of contexts. We have used theory and simulations to describe the response of homopolymers, with N monomers, to an external force (f ) in good and poor solvents. In good solvents and for sufficiently large N we show, in accord with scaling predictions, that the mean extension along the f axis 〈Z〉 ∼ f for small f and 〈Z〉 ∼ f 2/3 (the Pincus regime) for intermediate values of f. The theoretical predictions for 〈Z〉 as a function of f are in excellent agreement with simulations for N = 100 and 1600. However, even with N = 1600, the expected Pincus regime is not observed due to the breakdown of the assumptions in the blob picture for finite N. We predict the Pincus scaling in a good solvent will be observed for N ≳ 105. The force-dependent structure factors for a polymer in a poor solvent show that there is a hierarchy of structures, depending on the nature of the solvent. For a weakly hydrophobic polymer, various structures (ideal conformations, self-avoiding chains, globules, and rods) emerge on distinct length scales as f is varied. A strongly hydrophobic polymer remains globular as long as f is less than a critical value fc. Above fc, an abrupt first-order transition to a rodlike structure occurs. Our predictions can be tested using single molecule experiments. Greg Morrisongreg.morrison@imtlucca.itChangbong HyeonNgo Minh ToanBae-Yeun HaD.

We find for the roughness exponent a value ζ simeq 0.5 measured for "small length scales" in microfracturing experiments. Our simulations confirm that at small length scales the fracture can be considered as quasi-static. The isotropy of the roughness exponent on the crack surface is also showed. Finally, considering the crack front, we compute the roughness exponents of longitudinal and transverse fluctuations of the crack line (ζpar ~ ζ⊥ ~ 0.5). They result in agreement with experimental data, and support the possible application of the model of line depinning in the case of long-range interactions.Andrea ParisiGuido Caldarelliguido.caldarelli@imtlucca.itLuciano Pietronero2012-02-21T11:14:52Z2012-02-21T11:16:19Zhttp://eprints.imtlucca.it/id/eprint/1138This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/11382012-02-21T11:14:52ZReply to the Comment by H.

We use the Fourier method to compute the variance–covariance matrix of trading strategies. Our results indicate that well defined patterns arise. Two main communities of banks, which can be coarsely identified as small and large banks, emerge.Giulia IoriRenato RenòGiulia De MasiGuido Caldarelliguido.caldarelli@imtlucca.it2012-02-01T15:39:59Z2018-03-08T17:09:14Zhttp://eprints.imtlucca.it/id/eprint/1104This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/11042012-02-01T15:39:59ZEnsemble approach to the analysis of weighted networksWe present an approach to the analysis of weighted networks, by providing a straightforward generalization of any network measure defined on unweighted networks, such as the average degree of the nearest neighbors, the clustering coefficient, the “betweenness,” the distance between two nodes, and the diameter of a network. All these measures are well established for unweighted networks but have hitherto proven difficult to define for weighted networks. Our approach is based on the translation of a weighted network into an ensemble of edges. Further introducing this approach we demonstrate its advantages by applying the clustering coefficient constructed in this way to two real-world weighted networks.Sebastian E. AhnertDiego Garlaschellidiego.garlaschelli@imtlucca.itThomas M.A. FinkGuido Caldarelliguido.caldarelli@imtlucca.it2012-02-01T15:35:22Z2018-03-08T17:09:24Zhttp://eprints.imtlucca.it/id/eprint/1103This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/11032012-02-01T15:35:22ZInterplay between topology and dynamics in the World Trade WebWe present an empirical analysis of the network formed by the trade relationships between all world countries, or World Trade Web (WTW). Each (directed) link is weighted by the amount of wealth flowing between two countries, and each country is characterized by the value of its Gross Domestic Product (GDP). By analysing a set of year-by-year data covering the time interval 1950–2000, we show that the dynamics of all GDP values and the evolution of the WTW (trade flow and topology) are tightly coupled. The probability that two countries are connected depends on their GDP values, supporting recent theoretical models relating network topology to the presence of a `hidden' variable (or fitness). On the other hand, the topology is shown to determine the GDP values due to the exchange between countries. This leads us to a new framework where the fitness value is a dynamical variable determining, and at the same time depending on, network topology in a continuous feedback.

To elucidate the connection between the CSN topology and the underlying free-energy landscape governing the system dynamics and thermodynamics, an analytical solution is provided to explain the heavy tail of the degree distribution, neighbor connectivity, and clustering coefficient. This derivation allows us to understand the universal CSN topology observed in systems ranging from a simple quadratic well to the native state of the beta3s peptide and a two-dimensional lattice heteropolymer. Moreover, CSNs are shown to fall in the general class of complex networks described by the fitness model.David GfellerDavid Morton de LachapellePaolo De Los RiosGuido Caldarelliguido.caldarelli@imtlucca.itFrancesco Rao2012-02-01T14:01:47Z2018-03-08T17:09:03Zhttp://eprints.imtlucca.it/id/eprint/1101This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/11012012-02-01T14:01:47ZSelf-organized network evolution coupled to extremal dynamicsThe interplay between topology and dynamics in complex networks is a fundamental but widely unexplored problem. Here, we study this phenomenon on a prototype model in which the network is shaped by a dynamical variable. We couple the dynamics of the Bak–Sneppen evolution model with the rules of the so-called fitness network model for establishing the topology of a network; each vertex is assigned a 'fitness', and the vertex with minimum fitness and its neighbours are updated in each iteration. At the same time, the links between the updated vertices and all other vertices are drawn anew with a fitness-dependent connection probability. We show analytically and numerically that the system self-organizes to a non-trivial state that differs from what is obtained when the two processes are decoupled. A power-law decay of dynamical and topological quantities above a threshold emerges spontaneously, as well as a feedback between different dynamical regimes and the underlying correlation and percolation properties of the network.Diego Garlaschellidiego.garlaschelli@imtlucca.itAndrea CapocciGuido Caldarelliguido.caldarelli@imtlucca.it2012-02-01T13:51:08Z2012-02-01T13:51:48Zhttp://eprints.imtlucca.it/id/eprint/1100This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/11002012-02-01T13:51:08ZThe Italian interbank network: statistical properties and a simple modelWe use the theory of complex networks in order to quantitatively characterize the structure of reciprocal expositions of Italian banks in the interbank money market market. We observe two main different strategies of banks: small banks tend to be the lender of the system, while large banks are borrowers. We propose a model to reproduce the main statistical features of this market. Moreover the network analysis allows us to investigate properties of robustness of this system.Giulia De MasiGiulia IoriGuido Caldarelliguido.caldarelli@imtlucca.it2012-02-01T13:17:52Z2013-11-21T09:07:26Zhttp://eprints.imtlucca.it/id/eprint/1099This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/10992012-02-01T13:17:52ZSpectral methods cluster words of the same class in a syntactic dependency networkWe analyze here a particular kind of linguistic network where vertices represent words and edges stand for syntactic relationships between words. The statistical properties of these networks have been recently studied and various features such as the small-world phenomenon and a scale-free distribution of degrees have been found. Our work focuses on four classes of words: verbs, nouns, adverbs and adjectives. Here, we use spectral methods sorting vertices. We show that the ordering clusters words of the same class. For nouns and verbs, the cluster size distribution clearly follows a power-law distribution that cannot be explained by a null hypothesis. Long-range correlations are found between vertices in the ordering provided by the spectral method. The findings support the use of spectral methods for detecting community structure.Ramon Ferrer I CanchoAndrea CapocciGuido Caldarelliguido.caldarelli@imtlucca.it2012-01-26T14:19:40Z2014-12-05T09:24:53Zhttp://eprints.imtlucca.it/id/eprint/1086This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/10862012-01-26T14:19:40ZInvasion percolation and critical transient in the Barabási Model of human dynamicsWe introduce an exact probabilistic description for L=2 of the Barabási model for the dynamics of a list of L tasks. This permits us to study the problem out of the stationary state and to solve explicitly the extremal limit case where a critical behavior for the waiting time distribution is observed. This behavior deviates at any finite time from that of the stationary state. We study also the characteristic relaxation time for finite time deviations from stationarity in all cases showing that it diverges in the extremal limit, confirming that these deviations are important at all time.Andrea GabrielliGuido Caldarelliguido.caldarelli@imtlucca.it2012-01-25T13:12:31Z2012-01-25T13:12:31Zhttp://eprints.imtlucca.it/id/eprint/1077This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/10772012-01-25T13:12:31ZScale-free networks : complex webs in nature and technologyA variety of different social, natural and technological systems can be described by the same mathematical framework. This holds from the Internet to food webs and to boards of company directors. In all these situations, a graph of the elements of the system and their interconnections displays a universal feature. There are only a few elements with many connections and many elements with few connections. This book reports the experimental evidence of these ‘Scale-free networks’ and provides students and researchers with a corpus of theoretical results and algorithms to analyse and understand these features. The content of this book and the exposition makes it a clear textbook for beginners and a reference book for experts.Guido Caldarelliguido.caldarelli@imtlucca.it2012-01-20T10:45:29Z2012-01-25T13:10:14Zhttp://eprints.imtlucca.it/id/eprint/1076This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/10762012-01-20T10:45:29Z(edited by) Large scale structure and dynamics of complex networks: from information technology to finance and natural scienceThis book is the culmination of three years of research effort on a multidisciplinary project in which physicists, mathematicians, computer scientists and social scientists worked together to arrive at a unifying picture of complex networks.

We use longitudinal data of interfirm R&D collaborations in the biopharmaceutical industry in which a new technological regime is established. Our findings suggest that it requires radical technological change for firms to leave their embedded path of existing alliances and form new alliances with new partners. While new partners are mostly found through the firms’ existing network, we provide some insight into distant link formation with unknown partners, which contributes to our understanding of how ‘small-worlds’ might emergeSandra PhlippenMassimo Riccabonimassimo.riccaboni@imtlucca.it2011-10-31T14:19:25Z2012-01-18T08:01:43Zhttp://eprints.imtlucca.it/id/eprint/984This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/9842011-10-31T14:19:25ZSur l'interversion de l'ordre entre deux opérations sur les tribusWe characterize the measurable spaces (Ω,A) such that, for each sub-σ-field G of A and each decreasing filtered family (F_t) of sub-σ-fields of A, with F_t ↓ F_∞, we have F_t ∨ G ↓ F_∞ ∨ G.

Nella prima parte il volume sviluppa l'idea di patrimoine fra Rivoluzione, Impero e Restaurazione (Poulot), ma anche la storia della protezione del patrimonio culturale in Francia fino alla legge del 1913 (Lafarge) e sotto la V Repubblica (Poirier). Gli approfondimenti conducono al Novecento con il saggio Frier sulla legge del 1913 nonché la presentazione del nuovo Codice del patrimonio del 2004 (Lafarge) e i problemi del decentramento trattati da Leniaud che si rivelano molto istruttivi per un confronto con la situazione italiana.

Our main finding is that risk aversion cannot by itself explain a negative relationship between aggregate investment and aggregate uncertainty, as the effect of increased uncertainty on investment also depends on the intertemporal elasticity of substitution. In particular, the relationship between aggregate investment and aggregate uncertainty is positive even if agents are very risk averse, as long as the elasticity of intertemporal substitution is low. A negative investment-uncertainty relationship requires that the relative risk aversion and the elasticity of intertemporal substitution are both relatively high or both relatively low. We also show that the implications of our model are consistent with the available empirical evidence.Enrico SaltariDavide Ticchidavide.ticchi@imtlucca.it2011-08-08T14:07:37Z2012-05-30T07:12:23Zhttp://eprints.imtlucca.it/id/eprint/772This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7722011-08-08T14:07:37ZAn economic theory of constitutional choiceDavide Ticchidavide.ticchi@imtlucca.itAndrea Vindigniandrea.vindigni@imtlucca.it2011-08-03T10:52:17Z2011-08-04T07:30:21Zhttp://eprints.imtlucca.it/id/eprint/765This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7652011-08-03T10:52:17ZKriging metamodels in design optimization: an automotive engineering applicationGabriella Dellinogabriella.dellino@imtlucca.itPaolo LinoCarlo MeloniAlessandro Rizzo2011-08-03T10:42:23Z2011-08-04T07:30:21Zhttp://eprints.imtlucca.it/id/eprint/764This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7642011-08-03T10:42:23ZModeling and simulation study for the design of controlled IPMC actuatorsGabriella Dellinogabriella.dellino@imtlucca.itPaolo LinoCarlo MeloniAlessandro RizzoPaolo Di GiambernardinoAndrea Usai2011-08-02T10:17:52Z2011-08-04T07:30:21Zhttp://eprints.imtlucca.it/id/eprint/763This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7632011-08-02T10:17:52ZModels for the design and optimization of CNG injection systemsGabriella Dellinogabriella.dellino@imtlucca.itPaolo LinoCarlo MeloniAlessandro Rizzo2011-08-02T10:15:15Z2011-08-08T08:41:01Zhttp://eprints.imtlucca.it/id/eprint/762This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7622011-08-02T10:15:15ZOptimization issues in modeling IPMC devicesClaudia BonomoGabriella Dellinogabriella.dellino@imtlucca.itLuigi FortunaPietro GiannoneSalvatore GrazianiPaolo LinoCarlo MeloniAlessandro Rizzo2011-08-02T09:13:43Z2011-08-04T07:30:21Zhttp://eprints.imtlucca.it/id/eprint/759This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7592011-08-02T09:13:43ZPerformance evaluation of the evolution control in design optimization assisted by Kriging surrogatesGabriella Dellinogabriella.dellino@imtlucca.itCarlo MeloniPaolo LinoAlessandro Rizzo2011-08-01T10:52:00Z2011-08-04T07:30:21Zhttp://eprints.imtlucca.it/id/eprint/749This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/7492011-08-01T10:52:00ZEnhanced evolutionary algorithms for multidisciplinary design optimization: a control engineering perspectiveThis chapter deals with the application of hybrid evolutionary methods to design optimization issues in which approximation techniques and model management strategies can be used to guide the decision making process in a multidisciplinary context. An enhanced evolutionary algorithmic scheme devoted to design optimization is proposed, and its use in real applications is illustrated in the framework of the multidisciplinary design optimization (MDO). At this aim, a case study is discussed. It relies to the field of automotive engineering in which the design optimization of a system is carried out considering simultaneously both mechanical and control requirements. The studied system is the regulator of the injection pressure of an innovative common rail system for compressed natural gas (CNG) engines, whose engineering design optimization includes several practical and numerical difficulties. To tackle such a situation, a multiobjective optimization formulation of the problem is proposed. The adopted optimization strategy pursues the Pareto optimality on the basis of fitness functions that capture domain specific design aspects as well as static and dynamic objectives. The computational experiments show the ability of the proposed method for finding a satisfactory set of efficient solutions.

For equal numbers of zealots of each species, the distribution of magnetization (opinions) is Gaussian in the mean-field limit, as well as in one and two dimensions, with a width that is proportional to 1/√Z , where Z is the number of zealots, independent of the total number of voters. Thus just a few zealots can prevent consensus or even the formation of a robust majority.M. MobiliaAlexander M. Petersenalexander.petersen@imtlucca.itS.

We exploit the features of a unique longitudinal data set which covers the entire distribution of products and firms in the worldwide pharmaceutical industry to test the model at different levels of aggregation as well as at different time lags.

We show that the correlation between degree and betweenness centrality C of nodes is much weaker in fractal network models compared to nonfractal models. We also show that nodes of both fractal and nonfractal scale-free networks have power-law betweenness centrality distribution P(C)∼C−δ. We find that for nonfractal scale-free networks δ=2, and for fractal scale-free networks δ=2−1∕dB, where dB is the dimension of the fractal network. We support these results by explicit calculations on four real networks: pharmaceutical firms (N=6776), yeast (N=1458), WWW (N=2526), and a sample of Internet network at the autonomous system level (N=20566), where N is the number of nodes in the largest connected component of a network. We also study the crossover phenomenon from fractal to nonfractal networks upon adding random edges to a fractal network. We show that the crossover length ℓ*, separating fractal and nonfractal regimes, scales with dimension dB of the network as p−1∕dB, where p is the density of random edges added to the network. We find that the correlation between degree and betweenness centrality increases with p.Maksim KitsakShlomo HavlinGerald PaulMassimo Riccabonimassimo.riccaboni@imtlucca.itFabio Pammollif.pammolli@imtlucca.itH.

Mathematical treatmentWe present a preferential attachment growth model to obtain the distribution P(K) of number of units K in the classes which may represent business firms or other socio-economic entities. We found that P(K) is described in its central part by a power law with an exponent ϕ = 2+b/(1-b) which depends on the probability of entry of new classes, b. In a particular problem of city population this distribution is equivalent to the well known Zipf law. In the absence of the new classes entry, the distribution P(K) is exponential. Using analytical form of P(K) and assuming proportional growth for units, we derive P(g), the distribution of business firm growth rates. The model predicts that P(g) has a Laplacian cusp in the central part and asymptotic power-law tails with an exponent ζ = 3. We test the analytical expressions derived using heuristic arguments by simulations. The model might also explain the size-variance relationship of the firm growth rates.

Empirical evidenceWe introduce a model of proportional growth to explain the distribution P(g) of business firm growth rates. The model predicts that P(g) is Laplace in the central part and depicts an asymptotic power-law behavior in the tails with an exponent ζ = 3. Because of data limitations, previous studies in this field have been focusing exclusively on the Laplace shape of the body of the distribution. We test the model at different levels of aggregation in the economy, from products, to firms, to countries, and we find that the predictions are in good agreement with empirical evidence on both growth distributions and size-variance relationships.

Le misure recentemente adottate sono finalizzate a promuovere, attraverso l'iniezione di competitività, quel recupero di efficienza che le istituzioni comunitarie e i maggiori analisti indicano quale strumento per incentivare la crescita. Ma il permanere di rendite di posizione e di barriere alla concorrenza rende necessario intervenire sulle variabili strutturali in numerosi settori, attuando un più esteso programma di liberalizzazione capace di favorire l'affermazione di contesti realmente competitivi. Da queste premesse prendono spunto i contributi raccolti nel volume, per suggerire linee di intervento tese a facilitare l'accesso al mercato e la pluralità degli operatori e, per questa via, promuovere la produttività e la crescita.Fabio Pammollif.pammolli@imtlucca.itCarlo Cambinic.cambini@imtlucca.itAndrea Giannaccaria.giannaccari@imtlucca.it2011-03-30T10:16:41Z2011-07-11T14:21:53Zhttp://eprints.imtlucca.it/id/eprint/224This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/2242011-03-30T10:16:41ZIl caso LeeginNota a Corte Suprema degli Stati Uniti d’America, 28 giugno 2007, No. 06-480, Leegin Creative Leather Products, Inc. v.

Sono inoltre richiamate le tappe principali che hanno condotto all'attuale articolazione proprietaria, sfociata nella costituzione di Telco, e le criticità dell'"incumbent" nell'affrontare le sfide di un mercato sempre più globale. Nelle sezioni successive, sono approfondite le ipotesi di separazione funzionale della rete di accesso e la questione nodale degli investimenti necessari per il potenziamento delle infrastrutture di nuova generazione - le "Next Generation Networks" -. / The article analyses recent Telecom Italia changements in both shareholders structure as well as management composition, with specific emphasis on the agreement which has led to the creation of the Telco holding. The financial and industrial strategies of Telecom Italia are also scrutinised in the even more globalized telecomunication market, pointing out the many critical aspects that the Italian incumbent has to deal with and, above all, overcome. In this respect, it is also discussed the proposal of operational separation, which has been recently submitted to a public consultation by the Italian Regulatory Authority; and the issue of the necessary investments to boost the proper and sound development of the Next Generation Networks.

policy-based alienation and indifference in Brazil’s 2002 presidential election. The
results indicate that both alienation and indifference depressed turnout, with indifference
contributing slightly more to voter abstention. Also, the determinants of alienation and
indifference differed considerably, the former being determined by structural factors such
as voters’ information and perceived efficacy levels, while the latter was related to shortterm
aspects such as parties’ mobilization efforts. More importantly, evidence shows
that while alienation and indifference were strongly influenced by attitudinal and protest
variables, they were also affected by citizens’ evaluation of candidates’ ideological locations.
The main conclusion is that abstention in Brazil’s 2002 election had a policy-driven
component and that spatial considerations played a substantive role in citizens’ electoral
behavior, a fact that has been overlooked in previous research on the determinants of
abstention in Latin America.Gabriel Katzg.katz@imtlucca.it2011-02-15T10:50:21Z2011-07-11T14:24:17Zhttp://eprints.imtlucca.it/id/eprint/54This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/542011-02-15T10:50:21ZLa rivoluzione incompiuta di Thomas KuhnStefano Gatteistefano.gattei@imtlucca.it
