Coordination and Sociability for Intelligent Virtual Agents
2008
This paper presents a multi-agent framework designed to simulate synthetic humans that properly balance task oriented and social behaviors. The work presented in this paper focuses on the social library integrated in BDI agents to provide socially acceptable decisions. We propose the use of ontologies to define the social relations within an artificial society and the use of a market based mechanism to reach sociability by means of task exchanges. The social model balances rationality, to control the global coordination of the group, and sociability, to simulate relations (e.g. friendliness) and reciprocity among agents. The multi-agent framework has been tested successfully in dynamic envi…
A Strain Sensing Structural Health Monitoring System for Delaminated Composite Structures
2012
Structural Health Monitoring (SHM) for composite materials is becoming a primary task due to their extended use in safety critical applications. Different methods, based on the use of piezoelectric transducers as well as of fiber optics, has been successfully proposed to detect and monitor damage in composite structural components with particular attention focused on delamination cracks.In the present paper a Structural Health Monitoring model, based on the use of piezoelectric sensors, already proposed by the authors for isotropic damaged components, is extended to delaminated composite structures. The dynamic behavior of the host damaged structure and the bonded piezoelectric sensors is m…
Factors contributing to verbal self-disclosure
2007
The phenomenon of self-disclosure has been actively studied in several sub-discliplines of psychology from the 1970s on, and neighbouring disciplines, such as social and communication sciences, have enriched the psychological understanding of the topic. The psychological literature on self-disclosure, which is viewed, sometimes as a trait-like construct, varying in degree from one person to another, and sometimes as an interpersonal process which occurs when individuals interact with each other, has addressed, in particular, the issues of reciprocity effect, sex differences, self-disclosure in intimate vs. non-intimate relationships, the benefits to be derived from disclosing, and the emoti…
A hierarchy of simplified constitutive models within isotropic strain gradient elasticity
2017
Abstract Simplified isotropic models of strain gradient elasticity are presented, based on the mutual relationship between the inherent (dual) gradient directions (i.e. the gradient direction of any strain gradient source and the lever arm direction of the promoted double stress). A class of gradient-symmetric materials featured by gradient directions obeying a reciprocity relation and by 4 independent h.o. (higher order) coefficients is envisioned, along with the sub-classes of hemi-collinear materials (3 h.o. coefficients, gradient directions in part coincident), collinear materials (2 h.o. coefficients, equal gradient directions) and micro-affine materials (1 h.o. coefficient, behavioral…
On the Toeplitz algebras of right-angled and finite-type Artin groups
1999
The graph product of a family of groups lies somewhere between their direct and free products, with the graph determining which pairs of groups commute and which do not. We show that the graph product of quasi-lattice ordered groups is quasi-lattice ordered, and, when the underlying groups are amenable, that it satisfies Nica's amenability condition for quasi-lattice orders. As a consequence the Toeplitz algebras of these groups are universal for covariant isometric representations on Hilbert space, and their representations are faithful if the isometries satisfy a properness condition given by Laca and Raeburn. An application of this to right-angled Artin groups gives a uniqueness theorem …
Shallow and Deep Integration
2021
The concepts of shallow and deep economic integration are introduced and discussed as to their pertinence. The conflicting results of successive rounds of global trade negotiations for developing and least developed countries are examined in the context of deep integration attempts in North-South agreements. It is established as a guiding principle that North-South agreements should normally not go deeper or run faster than South-South agreements. In light of observed global trends, upcoming inter-regional trade deals will differ from current preferential North-South trade agreements, and Northern partners will be adamant that future agreements should go deep, as the chapter critically disc…
Selection by committee: Anonymity and gratitude
2018
Abstract What kind of candidate is selected into a job when the principal has to appoint a committee to measure the candidates’ ability and select a winner? We find that if the committee takes into account the candidate’s gratitude towards them, a candidate with less than first best ability will be selected. A relevant exception may occur if the first best is the overall best candidate. First best selection is always achieved if the committee is anonymous to the candidates. If the committee is not detached enough from the candidates then delegation fares even worse than random selection.
Networked relationships in the e-MID Interbank market: A trading model with memory
2014
Interbank markets are fundamental for bank liquidity management. In this paper, we introduce a model of interbank trading with memory. Our model reproduces features of preferential trading patterns in the e-MID market recently empirically observed through the method of statistically validated networks. The memory mechanism is used to introduce a proxy of trust in the model. The key idea is that a lender, having lent many times to a borrower in the past, is more likely to lend to that borrower again in the future than to other borrowers, with which the lender has never (or has in- frequently) interacted. The core of the model depends on only one parameter representing the initial attractiven…
Trust and punishment
2021
Abstract This paper explores the impact of institutions on the evolution of preferences (culture) and on economic outcomes. Punishment institutions determine the capacity and the individual cost of punishing opportunistic behavior, while preferences are endogenous and can be influenced by a cultural transmission process that is conditioned by the existing punishment institutions. We investigate the interaction and evolution between the preferences for reciprocity or rewarding of the allocator and the preferences to punish hostile behaviour by the investor in a trust game with a costly punishment phase. Our main result provides a rationale for the existence of a strong positive relationship …
L'educazione tra generi e generazioni
2020
Il contributo analizza il legame in educazione tra identità di genere e generazioni, intendendo con quest'ultimo termine sia l'aspetto generazionale sia quello generativo che troviamo all'interno di ogni storia familiare. La riflessione avviata approda all'idea di un'educazione che dovrebbe rendere consapevoli della reciprocità tra maschile e femminile come fondamento della comprensione della propria storia familiare e della costruzione del proprio sé. In quest'ultimo punto, il tema del genere si intreccia fortemente con quello delle generazioni, e quindi con la propria storia familiare, in cui il maschile e il femminile avranno assunto significati specifici, non sempre segnati dalla recipr…
