Representations of individuals in discourses oflaïcitéfromLe Monde: confirming or challenging the republican framework of identity?

2016

ABSTRACTIn recent decades, the notions of laicite and identity have been subjects of controversy in France. The two concepts have become sufficiently co-associated since the 1990s to ensure each almost systematically entails the other. Findings from previous studies have pointed out harmful implications of this pervasive association for minorities in France, especially Muslims. This study examines further the ways laicite and identity are interwoven by exploring who is represented (and how) in newspaper articles from Le Monde dealing with laicite. Informed by critical intercultural communication scholarship, intersectionality, and a Foucaultian approach to discourse, this study pays particu…

INTIMATE PARTNER VIOLENCE: PERCEPTION AND REPRESENTATION OF VIOLENCE AGAINST WOMEN IN GUANAJUATO. A QUALITATIVE RESEARCH

Intimate partner violence and domestic violence refer to the violation of women’s rights, often provoked by socio-cultural norms based on a patriarchal matrix. In Mexican society, in particular, gender-based violence affects the physical and psychological well-being of Mexican women. Moreover, the social representations of women who suffer violence and the lack of an effective legislative framework often reproduce the legitimation of gender-based violence, enhancing negative stereotypes and prejudices. In this scenario, the voice of the women who suffer violence in intimate relationships is silenced. In particular, in public and academic debates the impact and consequences of violence again…

Characterizations of {K,s+1}-Potent Matrices and Applications

2012

Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class of matrices that involve an involutory matrix, generalizing the well-known idempotent matrix, widely useful in many applications. In this paper, we introduce a new kind of matrices called {K,s+1}-potent, as an extension of the aforementioned ones. First, different properties of {K,s+1}-potent matrices have been developed. Later, the main result developed in this paper is the characterization of this kind of matrices from a spectral point of view, in terms of powers of the ma…

Preliminary investigations on indirect competition among Italian employers’ associations, and the relevant effects on collective bargaining

2022

Le associazioni dei datori di lavoro sono attori importanti per il sistema delle relazioni industriali e della contrattazione collettiva. I datori di lavoro e i sindacati in genere negoziano gli standard di lavoro in termini di salari e condizioni di lavoro per conto rispettivamente delle aziende associate e dei dipendenti. Sebbene la maggior parte della letteratura sulle relazioni industriali si sia concentrata principalmente sulla forza associativa e sulla densità associativa delle associazioni dei datori di lavoro, in questa pubblicazione a cura di Michele Faioli e Silvio Bologna, gli autori si discostano da questa prospettiva e si concentrano sul funzionamento e sulla governance, ovvero…

FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images

2019

Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…

Knowledge Representation in Extended Pawlak’s Information Systems: Algebraic Aspects

2002

The notion of an information system in Pawlak's sense is extended by introducing a certain ordering on the attribute set, which allows to treat some attributes as parts of others. With every extended information system S associated is the set K(S) of those pieces of information that, in a sense, admit a direct access in S. The algebraic structure of the "information space" K(S) is investigated, and it is shown, in what extent the structure of S can be restored from the structure of its information space. In particular, an intrinsic binary relation on K(S), interpreted as entailment, is isolated, and an axiomatic description of a knowledge revision operation based on it is proposed.

Knowledge Representation on the Web Revisited: The Case for Prototypes

2016

Recently, RDF and OWL have become the most common knowledge representation languages in use on the Web, propelled by the recommendation of the W3C. In this paper we examine an alternative way to represent knowledge based on Prototypes. This Prototype-based representation has different properties, which we argue to be more suitable for data sharing and reuse on the Web. Prototypes avoid the distinction between classes and instances and provide a means for object-based data sharing and reuse.

<title>HAP: a hybrid system for reasoning about actions and plans in robotics</title>

1990

The paper describes the main ideas and principles of HAP (Hybrid representation of Actions and Plans), a system for hybrid representation and reasoning in advanced robotics. In this context, hybrid representation refers to the integration of both symbolic and analogic knowledge representation paradigms. In particular, the logic/symbolic component is based on a KL-ONE-like representation language. The system embeds "analogic experts", that are concurrent procedures operating in a direct and fast way on the world representation. These "experts" help the system in planning a correct temporal sequence of actions. As a reference scenario, assembly (and disassembly) problems are considered. The a…

Handling Context-Sensitive Temporal Knowledge from Multiple Differently Ranked Sources

1999

In this paper we develop one way to represent and reason with temporal relations in the context of multiple experts. Every relation between temporal intervals consists of four endpoints’ relations. It is supposed that the context we know is the value of every expert competence concerning every endpoint relation. Thus the context for an interval temporal relation is one kind of compound expert’s rank, which has four components appropriate to every interval endpoints’ relation. Context is being updated after every new opinion is being added to the previous opinions about certain temporal relation. The context of a temporal relation collects all support given by different experts to all compon…

Reasoning with Multilevel Contexts in Semantic Metanetworks

2000

It is generally accepted that knowledge has a contextual component. Acquisition, representation, and exploitation of knowledge in context would have a major contribution in knowledge representation, knowledge acquisition, and explanation, as Brezillon and Abu-Hakima supposed in [Brezillon and Abu-Hakima, 1995]. Among the advantages of the use of contexts in knowledge representation and reasoning Akman and Surav [Akman and Surav, 1996] mentioned the following: economy of representation, more competent reasoning, allowance for inconsistent knowledge bases, resolving of lexical ambiguity and flexible entailment. Brezillon and Cases noticed however in [Brezillon and Cases, 1995] that knowledge-…
