Athènes et les « Philaïdes » Formes de réciprocité entre les aristocrates et la polis

2009

This article aims at exploring the relationship between Athens and the members of the Miltiades and Cimon family, the so-called Philaids. The history of this lineage significantly marked the development of Athens in the archaic period. In spite of the contradictory traditions regarding these historical figures, a lexical analysis of the sources allows an interpretation of their relationship with the polis in terms of reciprocity. I will argue that this is a special form of reciprocity, generated by the unequal and asymmetric relationship that this family seems to have had with Athens.

The legal balance between liberty and equality

2021

The paper explores the specific legal balance between liberty and equality, distinguishing it from political theories and constitutional settings, where they are often considered in opposition. In order to find the specific legal balance between liberty and equality, and after identifying some of their relevant meanings for the purpose, it becomes necessary to focus on the rule of law, and to examine the relationship between liberty and equality in its different versions. Once the core meaning of the rule of law in terms of liberty and equality is enucleated, it is possible to consider extending it to the international field.

Selection and Gratitude: Anonymity and gratitude

2018

What kind of candidate is selected into a job when the principal has to appoint a committee to measure the candidate's ability and select a winner through a call specifying a wage for the job? In a model where the principal fixes the wage anticipating the committee's choice, under a rather natural assumption about the committee's objective we find that if the committee takes into account the candidate's gratitude a candidate with less than first best ability will be selected in equilibrium. First best selection is achieved if the committee is anonymous to the candidates. If the committee could also set the wage the first best candidate would be selected, but the principal would be worse off…

La validación del clima de justicia y de la justicia entre compañeros en un entorno real de trabajo

2016

Abstract In this study we tested the validity of justice climate and peer justice, measured as second-order constructs, in a real work setting. First, we investigated the appropriateness of aggregating first-order facets of justice climate and peer justice to work-unit level of analysis. Second, we examined the construct validity of justice climate and peer justice as two different factor structures. Third, we tested the hierarchical structure of justice climate and peer justice as second-order factors. Finally, we examined the predictive validity of second-order factors justice climate and peer justice within a nomological network composed of reciprocity with the supervisor and reciprocity…

Parabolic Subgroups of Artin Groups

1997

Abstract Let ( A , Σ) be an Artin system. For X  ⊆ Σ, we denote by A X the subgroup of A generated by X . Such a group is called a parabolic subgroup of A . We reprove Van der Lek's theorem: “a parabolic subgroup of an Artin group is an Artin group.” We give an algorithm which decides whether two parabolic subgroups of an Artin group are conjugate. Let A be a finite type Artin group, and let A X be a parabolic subgroup with connected associated Coxeter graph. The quasi-centralizer of A X in A is the set of β in A such that β X β −1  =  X . We prove that the commensurator of A X in A is equal to the normalizer of A X in A , and that this group is generated by A X and the quasi-centralizer of…

Gaussian Groups and Garside Groups, Two Generalisations of Artin Groups

1999

It is known that a number of algebraic properties of the braid groups extend to arbitrary finite Coxeter-type Artin groups. Here we show how to extend the results to more general groups that we call Garside groups. Define a Gaussian monoid to be a finitely generated cancellative monoid where the expressions of a given element have bounded lengths, and where left and right lowest common multiples exist. A Garside monoid is a Gaussian monoid in which the left and right lowest common multiples satisfy an additional symmetry condition. A Gaussian group is the group of fractions of a Gaussian monoid, and a Garside group is the group of fractions of a Garside monoid. Braid groups and, more genera…

Pictorial meaning-making in a community project in Helsinki. Freirean interpretations of a dialogical process

2018

Participation in public discourse belongs to a democratic citizenship. However, part of the population is excluded from such communal discussion. This paper describes how the photography group Camera Obs., which principally contained unemployed people in Helsinki, created pictorial voices from their own everyday experiences through a dialogical process, rendering them also visible to other people. The research focuses on the group’s activity during the years 2004–6, from the beginning of the project to its first exhibition. As a theoretical background, Paulo Freire’s ideas of dialogue and voice creation, combined with Vygotsky’s and Mezirow’s concept of meaning-making, have been applied. T…

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…
