An Approach for the Design of Self-conscious Agent for Robotics
2010
Developing complex robotic systems endowed with self- conscious abilities and subjective experience is a hard requirement to face at design time. This paper deals with the development of robotic systems that do not own any a-priori knowledge of the environment they live in and proposes an agent-orientd design process for modelling and implementing such a systems by means of implementing the perception loop occurring between environment, body and brain during subjective experience. A case study dealing with a robocup setup is proposed in order to describe the design process activities and to illustrate the techniques for making the robot able to autonomously decide when an unknown situations…
A method for identifying objectives and metrics of agent-based simulation studies
2016
Agent-Based Modeling and Simulation (ABMS) is a promising approach for effectively analyzing, and under- standing complex systems. To date, only few method- ological approaches have been proposed in order to de- sign credible and correct simulation studies. Each of them commits the identification of objectives and met- rics of the simulation study to the expertise of the de- signer. In this paper, we propose a GQM-based heuris- tic for overcoming the lack of appropriate guidelines able to lead designers in properly capturing and representing the simulation objectives and metrics. Such a heuris- tic exploits the power of an ontological representation of the problem domain to highlight key el…
A Methodology for Graphical Modeling of Business Rules
2011
This work proposes a novel methodology based on the Business Process Modeling Notation (BPMN) standard capable of graphically modeling business rules. A set of new representation patterns allows business analysts to map processes described through BPMN into conditions and actions of business rules. Our approach exploits Domain Specific Language techniques in order to make the methodology independent from the programming language supported by the specific rule engine. Moreover, this work proposes a web graphical editor, instantiated on a specific sample scenario, where the selected rule engine is Drools, one of the most used open source products. The developed editor allows business analysts…
Metamodel-based metrics for agent-oriented methodologies
2012
A great number of methodologies has been already intro duced in the agent-oriented software engineering field. Recently many of the authors of these methodologies also worked on their fragmentation thus obtaining portions (often called method or process fragments) that may be composed into new methodologies. The great advancement in this field, however does not correspond to equivalent results in the evaluation of the methodologies and their fragments. It is, for instance, difficult to select a fragment in the composition of a new methodology and to predict the methodology’s resulting features. This work introduces a suite of metrics for evaluating and comparing entire methodologies but als…

Recensione del volume di Daniel Barbu, Philippe Borgeaud, Mélanie Lozat, Nicolas Meylan, Anne-Caroline Rendu Loisel (ed.), Le savoir des religions : fragments d'historiographie religieuse. Gallion: Infolio Editions, 2014. Il volume mostra le diverse declinazioni attraverso cui il “sapere delle religioni” si costruisce oppure entra, in momenti particolari, in crisi o partecipa a più ampi processi di ristrutturazione dell’orizzonte di senso è dunque lo scopo principale di quest’opera, che si articola in tre sezioni, ciascuna delle quali si concentra su un differente grado di riflessività dei saperi “religiosi”.
«[…] tanta potenza di critica e tanta solida dottrina archeologica»: Pietro Selvatico, Santo Varni e l’erudizione artistica agli albori dell’Unità d’…
2018
Il volume raccoglie una serie di contributi sulla personalità multiforme di Santo Varni (1807-85), fin qui conosciuto soprattutto come scultore, di cui vengono indagati i suoi molteplici altri interessi: dall’archeologia alla storia dell’arte, dal collezionismo al restauro. Le sue tante atti-vità lo hanno condotto a studiare, oltre che la sua città, Genova, il Basso Piemonte, Savona, la Lomellina, il Tigullio e la Versilia. A partire da un fondo archivistico di Santo Varni inedito e da alcune opere rintracciate per l’occasione, il volume ricostruisce gli studi e le scoperte ef-fettuate dallo scultore, ricollegandole ai materiali superstiti, oggi dispersi nei musei di tutto il mondo (da quel…
Review of Marcel Boumans and Matthias Klaes (eds) (2013). Mark Blaug: Rebel with Many Causes. Cheltenham, UK and Northampton, MA, USA: Edward Elgar
2015
Mark Blaug passed away on November 18, 2011. To honor his memory, two events were held in March 2012: a Memorial Conference at the Erasmus Institute for Philosophy and Economics, Rotterdam (NL), and a seminar hosted by the Scottish Centre for Economic Methodology at the University of Glasgow (UK). As Marcel Boumans and Matthias Klaes point out in their editorial Introduction, this book contains a collection of papers given at these two events and includes some additional papers submitted by people who were not able to attend the meetings “at such short notice” (p. 5). In addition, the book carries a Foreword by Alan Peacock and consists of two parts: part I has four chapters—written by John…

A Generalized Missing-Indicator Approach to Regression with Imputed Covariates
2011
We consider estimation of a linear regression model using data where some covariate values are missing but imputations are available to fill in the missing values. This situation generates a tradeoff between bias and precision when estimating the regression parameters of interest. Using only the subsample of complete observations does not cause bias but may imply a substantial loss of precision because the complete cases may be too few. On the other hand, filling in the missing values with imputations may cause bias. We provide the new Stata command gmi, which handles such tradeoff by using either model reduction or Bayesian model averaging techniques in the context of the generalized miss…
Survey, tourism
2015
A survey is any organized and methodical activity that directly collects information on motivations, opinions, and behaviors about the characteristics of a given population, including tourists and residents of a destination. This article provides a description of the stages required when implementing a survey, for the Encyclopedia of Tourism, placing peculiar attention to the context of tourism.
