Farewell to representation: text and society
2017
Cultures develop the criteria to construct and recognize their texts, and pose them as normal, usual, ‘natural’. For us a book is a text, in Middle Ages for everyone a city was a text. But when it is necessary to critically inspect such a culture by analyzing its texts, it becomes necessary to understand their conditions of possibility and their functioning. So, from the semiotic point of view the text is something that needs to be recognized and constructed at the same time, that is to say invented according to the double meaning this word has for the ancient rhetoric (recovering) and for modern science (creating) (Marrone 2014). This is true for the semiotician who search for the fundamen…
Non-negative matrix factorization Vs. FastICA on mismatch negativity of children
2009
In this presentation two event-related potentials, mismatch negativity (MMN) and P3a, are extracted from EEG by non-negative matrix factorization (NMF) simultaneously. Typically MMN recordings show a mixture of MMN, P3a, and responses to repeated standard stimuli. NMF may release the source independence assumption and data length limitations required by Fast independent component analysis (FastICA). Thus, in theory NMF could reach better separation of the responses. In the current experiment MMN was elicited by auditory duration deviations in 102 children. NMF was performed on the time-frequency representation of the raw data to estimate sources. Support to Absence Ratio (SAR) of the MMN co…
Social representations and brand positioning in the sporting goods market
2013
Abstract This paper examines the use of social representations as a strategic tool to understand better and measure how consumers arrive at their identification of brand positioning (legitimacy and differentiation) in the brand's market. By considering the market as co-produced by brands and consumers (‘B&C approach’), this study classifies free-word associations connected to the brands into units of meanings, which constitute the core of a brand's market. We applied this tool to the four main brands in the French sporting goods market (i.e., Nike, Adidas, Reebok and Puma). Results show that the differentiation of brand positioning depends on legitimate elements of the market, such as adver…
International place branding through sporting events: a British perspective of the 2008 Beijing Olympics
2012
International audience; The goal of this study is to examine if hosting major sporting events represents a relevant strategy to brand a place ‘internationally’ through brand association transfer and to identify whether or not it should be seen as co-branding process. Based on social representation theory and an abductive research strategy, a survey was carried out among British citizens to identify their opinions about the Olympic Games and the city of Beijing following the organisation of the Games in August 2008. The content and the structure of the social representations were analysed and then compared to determine whether or not a double transfer of associations occurred between the pla…
La representación de la "femme fatale" en el universo narrativo de "Muerte de un ciclista" (Juan Antonio Bardem, 1955)
2017
Este artículo analiza la representación de la femme fatale en Muerte de un ciclista (Juan Antonio Bardem, 1955) como un recurso sintomático de la disidencia de Bardem respecto a la dictadura franquista. Partiendo de una perspectiva interdisciplinar que considera las aportaciones de la teoría semiótica y la teoría fílmica feminista, se aplica una metodología de análisis textual que atiende tanto a la estructura narrativa del film como a los procesos de significación, visuales y sintácticos, asociados a la femme fatale. Las conclusiones del análisis muestran un estereotipo fuertemente codificado y anclado en la narrativa clásica de la sanción, revelando la dificultad de articular, en el cine …
The Geometry of a Domed Architecture: A Stately Example of Kārbandi at Bagh-e Dolat Abad in Yazd
2016
This paper analyses the kārbandi of the Hashti pavilion at Bagh-e-Dolat Abad in Yazd. Kārbandi is a spatial system obtained through the projection of a star-shaped drawing onto a curved surface. It is characterised by a complex use of geometry and repetitive symmetry. The analysis of its geometrical aspects contributes to an understanding of the traditional rules underlying the original design. The kārbandi of the octagonal vestibule of the Hashti pavilion consists of a complex roof system that completes the octagonal volume of the room below; its intrados presents a pattern of interlocking ribbed arches. The paper also looks at the drawings, module and proportions of the Hashti pavilion, w…
Ambient Art : Creative Information Representation
2007
Ambient art is the aesthetic presentation of information, using artistic techniques to achieve a pleasing image that also contains hidden depths, where exposure to it over time allows a viewer to understand something about the information sources that it represents. This paper reviews the artistic and computational background of ambient systems, and presents two case studies of systems developed by our research team, from their initial design to the experiences of the people encountering them. The first case presents a photo mosaic of images based on the news headlines coupled with a structured picture based on the weather; the second presents stylistic perspectives on activity in a public …
Childhood reproduced: images of childhood represented in children's daily lives in home and day-care settings
2016
ABSTRACTThis study explores images of childhood by analysing children's pictorial representations and accompanying captions. The focus is on how children together with adults represent childhood in the home and daycare settings in a oneweek diary study. The key analytical tool was framing, which is used to highlight what kinds of images are (re)produced and narrated. The frames that emerged were (1) portrayal of the child via cultural products and societal relations, (2) portrayal of the child via individuality, relationships and attachment, (3) the child as a symbol of capabilities, and (4) the child as a learner. While illustrating how childhood was intertwined with consumption, cultural …
Design of a customized pattern for improving color constancy across camera and illumination changes
2010
International audience; This paper adresses the problem of color constancy on a large image database acquired with varying digital cameras and lighting conditions. Automatic white balance control proposed by an available commercial camera is not sufficient to provide reproducible color classification. A device-independent color representation may be obtained by applying a chromatic adaptation transform, from a calibrated color checker pattern included in the field of view. Instead of using the standard Macbeth color checker, we suggest to select judicious colors to design a customized pattern from contextual information. A comparative study demonstrates that this approach insures a stronger…
The Black Mediterranean: A View from Sicily
2021
While Italy has recently experienced nationalist drives, Sicily and in particular the City of Palermo, one of the major ports of refuge for countless migrants arriving in Europe from the African shores, has distinguished itself as an experimental site where to rethink and challenge notions of residence, mobility, citizenship and belonging. Through a series of cultural initiatives, Palermo has become a hub for frontline artists, writers, intellectuals, and activists who have gathered to explore the historically and contemporary ways in which black voices have been silenced and black bodies have been ambiguously imagined in Western-dominated global culture. Investigating these questions is fu…
