L'acceptation des dispositifs technologiquesd'auto-production par le consommateur : une approche par l'empowerment psychologique

2022

During the Covid-19 pandemic, the deployment of self-service technologies (self-checking, interactive terminals, smart devices…), allowing to substitute existing service employees and give more autonomy to consumers, have accelerated. In the french academic literature, Cova et al. (2013) conceptualized these devices as « directed self-production » technologies, underlining a more or less imposed transfer of tasks operated by firms. Among consumers, these technological devices have been subjected to ambivalent representations from consumers : some positive representations mainly related to greater autonomy for individuals exist alongside concerns about human contact degradation, macrostructu…

Back to the Amitsur-Levitzki theorem: a super version for the orthosymplectic Lie superalgebra osp(1, 2n)

2003

We prove an Amitsur-Levitzki type theorem for the Lie superalgebras osp(1,2n) inspired by Kostant's cohomological interpretation of the classical theorem. We show that the Lie superalgebras gl(p,q) cannot satisfy an Amitsur-Levitzki type super identity if p, q are non zero and conjecture that neither can any other classical simple Lie superalgebra with the exception of osp(1,2n).

Graphic representation of data resulting from measurement comparison trials in cataract and refractive surgery.

2003

* BACKGROUND AND OBJECTIVES: The evaluation of new diagnostic measurement devices allows intraindividual comparison with an established standard method. However, reports in journal articles often omit the adequate incorporation of the intraindividual design into the graphic representation. * PATIENTS AND METHODS: This article illustrates the drawbacks and the possible erroneous conclusions caused by this misleading practice in terms of recent method comparison data resulting from axial length measurement in 220 consecutive patients by both applanation ultrasound and partial coherence interferometry. * RESULTS: Graphic representation of such method comparison data should be based on boxplots…

Unbounded Linear Operators in Hilbert Spaces

2002

In order to make this monograph self-contained, we summarize in this chapter some basic definitions and results for unbounded linear operators in a Hilbert space. In Section 1.1, we recall the definitions of C*-algebras and von Neumann algebras. In Section 1.2, we define and investigate the notion of closedness, the closure and the adjoint of an unbounded linear operator in a Hilbert space. Section 1.3 is devoted to the Cayley transform approach to the self-adjointness of a symmetric operator. Section 1.4 deals with the self-adjoint extendability of a symmetric operator with help of the deficiency spaces. In Section 1.5, we extend to unbounded self-adjoint operators the spectral theorem and…

Bengali nasal vowels: Lexical representation and listener perception

2022

This paper focuses on the question of the representation of nasality as well as speakers’ awareness and perceptual use of phonetic nasalisation by examining surface nasalisation in two types of vowels in Bengali: underlying nasal vowels (CṼC) and nasalised vowels before a nasal consonant (CVN). A series of three cross-modal forced-choice experiments was used to investigate the hypothesis that only unpredictable nasalisation is stored and that this sparse representation governs how listeners interpret vowel nasality. Visual full-word targets were preceded by auditory primes consisting of CV segments of CVC words with nasal vowels ([tʃɑ̃] for [tʃɑ̃d] ‘moon’), oral vowels ([tʃɑ] for [tʃɑl] ‘un…

MODULAR KNOWLEDGE REPRESENTATION IN ADVISOR AGENTS FOR SITUATION AWARENESS

2011

A modular knowledge representation framework for conversational agents is presented. The approach has been realized to suit the situation awareness paradigm. The modularity of the framework makes possible the composition of specific modules that deal with particular features, simplifying both the chatbot design process and its smartness. As a proof of concepts we have developed a modular, situation awareness oriented, KB for a conversational agent, which plays the role of an advisor aimed at helping a user to be in charge of a virtual town, inspired to the SimCity series game. The agent makes an extensive use of semantic computing techniques and is able to perceive, comprehend and project c…

Cognitive status and referential acts in functional discourse grammar

2018

In Functional Discourse Grammar, both Ascription and Reference are characterized as actional processes and are captured at the Interpersonal Level of linguistic description. Additionally, the temporal sequencing of Discourse Acts seems relevant to establishing dependency relations among them. However, the remainder of the levels of representation in the theory contain static descriptions of linguistic structures and not of processes. In this paper, I will argue that this is the result of an inherent contradiction between FDG’s characterization as a static grammar and the dynamicity of verbal interaction, which is best solved if the theory commits itself to the procedural nature of the Inter…

Whose quality? Social actors in the interface of transnational and national higher education policy

2008

The article analyzes the construction of national reactions to a transnational higher education policy from the point of view of the representation of social actors in policy documents. The data are provided by the so-called Bologna Process, particularly the development of comparable quality assurance systems, and Finnish responses to those demands. Who is represented as active and who as passive, as European policies are discursively translated into national policies? How are those ‘quality actors’ represented in the policy documents directed at a transnational audience (i.e. the Bologna Process communiques, as well as national reports on its advancement) as opposed to documents directed a…

Memoria y ficción en El material humano de Rodrigo Rey Rosa: la representación imposible de la violencia en Guatemala

2017

El presente artículo analiza la novela de Rodrigo Rey Rosa, El material humano (2009), y la representación de la violencia que propone en su investigación sobre la realidad histórica de Guatemala a lo largo del siglo xx. El protagonista inicia una labor de indagación sobre las causas de la violencia de su país, para intentar comprender el origen del conflicto. Sin embargo, esta labor terminará con un triple fracaso: el cognoscitivo, el expresivo y el deontológico, representativos de toda una serie de narraciones sobre la memoria histórica en América Latina y España. This paper analyzes Rodrigo Rosa’s novel El material humano (2009), especially its representation of violence as seen through …
