Effetti spaziali o settoriali? La crescita della dimensione media d'impresa in Italia
2015
Utilizzando una recente versione della shift-share con struttura spaziale, in questo contributo scomponiamo il cambiamento della dimensione media delle imprese nelle province italiane rispetto a componenti di natura sia spaziale (di regione e di vicinato) che settoriale. L’analisi, condotta con riferimento al periodo 2004-2009, mette in risalto differenze di rilievo rispetto la classe dimensionale considerata. In particolare, si registra una netta demarcazione Nord-Sud nella distribuzione provinciale degli effetti spaziali e settoriali se consideriamo le micro imprese (1-10 addetti), mentre la geografia appare molto piu complessa per le piccole imprese (11-50 addetti).
Luoghi urbani scomparsi e architetture mai realizzate nella riconfigurazione 3D del Rione Conceria di Palermo
2018
L'oggetto di studio è lo scomparso Rione Conceria all'interno del Centro Storico di Palermo. È una vasta area urbana, che si estende lungo la Via Maqueda, Via Roma, Corso Vittorio Emanuele e Via Bandiera, che storicamente faceva parte di un unico sistema urbano che cuciva il mercato del Capo con il Mercato della Vucciria. Le operazioni urbanistiche del secolo scorso (il taglio di via Roma, il il progetto di riorganizzazione dell'intero rione, la costruzione della Galleria delle Vittorie) hanno cancellato quasi definitivamente sia le sue presenza architettoniche che l'impianto del suo tessuto viario. The object of study is the disappeared Rione Conceria inside the Historical Center of Palerm…
Immagine urbana e qualità dello spazio nel rilievo tridimensionale di due borgate storiche palermitane
2014
Lo sviluppo dei software di rappresentazione digitale ha comportato una significativa evo- luzione dei modelli rappresentativi, aprendo contemporaneamente la strada a nuove que- stioni di natura non soltanto operativa, ma anche sostanziale. L’assenza di scala di riduzione, la tridimensionalità in “real time”, l’immersività e l’interattività dello spazio virtuale sono infatti ben più di semplici novità strumentali: si pongono come nuovi codici, introducono una visibilità simultanea e onnicomprensiva, definiscono il modello che si viene a elaborare come un “alter” dello spazio indagato, autonomo e parallelo alla realtà stessa, ben più insomma del ruolo di “model- lo” del reale al quale la rap…
Multi-class pairwise linear dimensionality reduction using heteroscedastic schemes
2010
Accepted version of an article published in the journal: Pattern Recognition. Published version on Sciverse: http://dx.doi.org/10.1016/j.patcog.2010.01.018 Linear dimensionality reduction (LDR) techniques have been increasingly important in pattern recognition (PR) due to the fact that they permit a relatively simple mapping of the problem onto a lower-dimensional subspace, leading to simple and computationally efficient classification strategies. Although the field has been well developed for the two-class problem, the corresponding issues encountered when dealing with multiple classes are far from trivial. In this paper, we argue that, as opposed to the traditional LDR multi-class schemes…
Introduction : From Fundamentals to Advances in Crowdfunding Research and Practice
2020
AbstractThe chapter introduces the phenomenon of crowdfunding while presenting its definition and main manifestations in recent years. It then discusses the roles played by the various parties to a crowdfunding transaction, as well as the benefits each may gain from such engagement. Overall, it argues for a win-win situation, where all parties become better off from involvement in a responsible crowdfunding engagement. Furthermore, the chapter highlights the process dimension of crowdfunding, as represented through a series of three main stages, which are further specified into a seven sub-stage model. Each stage in the process depends on successful completion of the stage preceding it and …
THE THEORETICAL ASPECTS OF WELL-BEING IN THE CONTEXT OF LIFELONG LEARNING
2017
In 2006 the European Parliament and European Union Council has defined eight key competences for lifelong learning, necessary for personal fulfillment and development, active citizenship, social inclusion and employment. Since the economic crisis of 2008, the world is looking for new ways and methods to ensure the well-fare and reformulate the value of human life. Currently at EU level, one of the most important debates closely connected with the basic context of lifelong learning is on the dimensions of life quality.

Conceptualizing the European multilevel administrative order: capturing variation in the European administrative system
2015
Acknowledging that both analysts and practitioners face problems of meaningful categorization of social order in general, and the European political-administrative system in particular, this article suggests a conceptual frame through which European administrative order may be understood. Providing such a frame is important, because the catalogue of categories of the European Union (EU) polity developed so far fails to acknowledge its administrative dimension. Given that the ongoing political transformation in the EU implies ever more administrative interaction between political levels in order to coordinate, manage and implement policies, this administrative dimension becomes ever more imp…
Conceptualizing Online Discussion Value: A Multidimensional Framework for Analyzing User Comments on Mass-Media Websites
2013
This chapter provides a micro-framework for analyzing the quantity and quality of online user comments on mass-media websites. On one dimension, news factors of news items and discussion factors of existing user comments are assumed to indicate the relevance of participating in online discussions. On a second dimension, specific motivational, social, and design factors are influential when reconstructing users’ decisions to participate in online discussions and when analyzing the content of online user comments. The two dimensions in combination describe the discussion value of news items. Potential applications of this framework on other forms of interpersonal communication are discussed.
The value trade-off in higher education service: A qualitative intercultural approach to students’ perceptions
2016
Purpose: Higher Education Institutions (HEIs) have become a highly competitive market, where consumers (i.e. students) are highly involved in their choices, and managers need to focus on competitive edges. This paper aims to understand the factors that influence international Master students’ choice behaviour and fulfil student expectations of customer value in HEIs. Design/methodology: With qualitative information (five focus groups) collected from international students (of 12 different nationalities) of several universities in Spain, UK and China, the paper investigates the formation of customer value as a trade-off between benefits and costs. This qualitative approach aims first at asse…
The Role of Public Entity in Coopetiotion and Convergence
2007
We investigate upon the strategic impact of the public entity to catalyze coalition formation among competitors around an essential facility. The public entity is usually represented as if moved by mere political scopes. However, the presence of a publicly-owned asset or infrastructure, which can be termed an essential facility, gives leeway to shed the opportunity to satisfy potentially new and different type of demand or consumer cluster needs. The increase in value stemming from a renewal in the utilization of the facility might loosen up political restraints against the involvement in the management of the facility of a multiplicity of actors. This allows us to add a new dimension to th…
