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).
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…
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 …
Representation and videography in linguistic landscape studies
2017
AbstractMuch Linguistic Landscape scholarship relies on visual data collection, primarily the use of still photography; however, the field has yet to address the theoretical underpinning of such visual and spatial representation. Furthermore, digital video is currently as easy to capture and share as digital photographs were when Linguistic Landscape studies first became prominent in the early 2000s. With these two points in mind, this article first grounds the documentation and analysis of the Linguistic Landscape in a theory of visual representation; it then provides a framework for videographic methodologies drawing on recent work in the related fields of anthropology and cultural geogra…
Understanding dynamic scenes
2000
We propose a framework for the representation of visual knowledge in a robotic agent, with special attention to the understanding of dynamic scenes. According to our approach, understanding involves the generation of a high level, declarative description of the perceived world. Developing such a description requires both bottom-up, data driven processes that associate symbolic knowledge representation structures with the data coming out of a vision system, and top-down processes in which high level, symbolic information is in its turn employed to drive and further refine the interpretation of a scene. On the one hand, the computer vision community approached this problem in terms of 2D/3D s…
A cognitive approach to goal-level imitation
2008
Imitation in robotics is seen as a powerful means to reduce the complexity of robot programming. It allows users to instruct robots by simply showing them how to execute a given task. Through imitation robots can learn from their environment and adapt to it just as human newborns do. Despite different facets of imitative behaviours observed in humans and higher primates, imitation in robotics has usually been implemented as a process of copying demonstrated actions onto the movement apparatus of the robot. While the results being reached are impressive, we believe that a shift towards a higher expression of imitation, namely the comprehension of human actions and inference of its intentions…
Dodatno svjedočanstvo. Fotografije u prozi Daše Drndić
2020
In this paper I will reflect on the role of photographs in the works of Daša Drndić. Mixing fictional and documentary modes is a characteristic feature of her texts. It is achieved among others by utilizing visual representations of the past. In my paper I aim to outline the strategies of visualization applied by the authoress (especially the traumatic, Holocaust-related experience), which materialize through photographs included in her works of literature. In the case of Drndić the visuals include for instance contemporary or archival photographs of places marked by the Holocaust and of Jewish inhabitants of Vienna as well as portraits of war criminals. Generally speaking, in her texts the…
The morpheme gender effect.
2008
In three experiments we explored the mental representation of morphologically complex words in French. Subjects were asked to perform a gender decision task on morphologically complex words that were of the same gender as their base or not. We found that gender decisions were made more slowly for morphologically complex words made from a base with an opposite gender compared to words for which the gender of the base matches that of the derived noun. Similar results were obtained for words that are pseudo-morphologically complex while no effect was observed for non-morphological embedded words. Our results suggest that during gender identification of derived and pseudo-derived words, morphem…
