Does Empirical Embeddedness Matter? Methodological Issues on Agent-Based Models for Analytical Social Science
No full textThe paper deals with the use of empirical data in social science agent-based models. Agent-based models are too often viewed just as highly abstract thought experiments conducted in artificial worlds, in which the purpose is to generate and not to test theoretical hypotheses in an empirical way. On the contrary, they should be viewed as models that need to be embedded into empirical data both to allow the calibration and the validation of their findings. As a consequence, the search for strategies to find and extract data from reality, and integrate agent-based models with other traditional empirical social science methods, such as qualitative, quantitative, experimental and participatory methods, becomes a fundamental step of the modelling process. The paper argues that the characteristics of the empirical target matter. According to characteristics of the target, ABMs can be differentiated into case-based models, typifications and theoretical abstractions. These differences pose different challenges for empirical data gathering, and imply the use of different validation strategies.Agent-Based Models, Empirical Calibration and Validation, Taxanomy of Models
On some components of Hilbert schemes of curves
No full textLet be the union of irreducible components of the
Hilbert scheme whose general points parametrize smooth, irreducible, curves of degree , genus , which are non--degenerate
in the projective space . Under some numerical assumptions on , and , we construct irreducible components of
other than the so-called {em distinguished component}, dominating the moduli space
of smooth genus-- curves, which are generically smooth and
turn out to be of dimension higher than the expected one. The general point of any
such a component corresponds to a curve which is a suitable ramified --cover of an irrational curve
, , lying in a surface cone over .

Nervi e la prefabbricazione srutturale: lo stadio Flaminio a Roma (1957-59) / Nervi and the structural prefabrication: the Flaminio Stadium in Roma (1957-59)
No full textAttraverso l’analisi del progetto esecutivo e dell’opera costruita, gli autori hanno ricostruito le specifiche modalità realizzative basate sulla 'prefabbricazione strutturale' utilizzate da Pier Luigi Nervi per la realizzazione dello Stadio Flaminio. Il contributo mette in luce la specificità e l’originalità delle soluzioni adottate da Nervi e il suo talento di progettista e di costruttore

No full textEconomic Performance, Inter-Firm Relations and Local Institutional Engineering in a Computational Prototype of Industrial Districts
No full textIndustrial districts can be conceived as complex systems characterised by a network of interactions amongst heterogeneous, localised, functionally, integrated and complementary firms. In a previous paper, we have introduced an industrial district computational prototype, showing that the economic performance of an industrial district proceeds to the form through which firms interact and co-ordinate each others. In this paper, we use such computational framework to experiment different options of local institutional engineering', trying to understand how specific supporting institutions' could perform macro-collective activities, such as, i.e., technology research, transfer and information, improving the technological adaptation of firms. Is a district more than a simple aggregation of localised firms? What can explain the economic performance of firms localised into the same space? Could some options of 'local institutional engineering, improve the performance of a district? Could such options set aside the problem of how firms dynamically interact? These are questions explored in this paper
