Le nature del trucco. Forme e sostanze del make-up green
2022
The paper examines the semiotic articulation of naturality through a structural analysis of green make-up packaging. The relations this universe establishes with its opposite, that of “traditional” make-up, find manifestation in the way the three visual strategies implemented by make-up brands and identified through the analysis enhance continuity or discontinuity with respect to this figurative universe. An attempt will be made to show the complex discursive construction of nature through often heteroclite discourses within which differentiated isotopes can be found. Still, besides being brand choices that differentially articulate the theme of nature from an aesthetic point of view, each …
El edificio gremial de los abaixadors o tundidores, en Valencia
2020
In the ?barri del mercat?, in the city of Valencia and very close to its Lonja, there is a building complex which is the object of this study. The research, carried out from the simple field of toponymy, to the constructive analysis, lead us to suppose that it is the building of the Valencian trade union of cloth-shearers. It can be seen how the building now camouflaged by other subsequent interventions, corresponds to a type that cannot be related to those usually built in the city of Valencia. Its origins clearly from the Valencian self-governing period splendor, its dimensions and the finishes used in its construction seem to refer to a medieval workshop. A structure of great importance …
L’estetica del camuffamento animale. Riflessioni sul mimetismo biologico
2016
This article wants to investigate the logic of mimicry and their communicative function in animal life adopting an aesthetical perspective. The relationship between appearance and not-appearance, between the act of making itself visible and the act of disguising itself, is investigated starting from the morphological thought of the Swiss biologist Adolf Portmann, in a continuous dialogue with great thinkers of past and actual time – Johann Wolfgang Goethe, Hannah Arendt and Roger Caillois – and with the artistic illustrations of the American painter Abbott Thayer, concerned with the laws of color camouflage. This productive relationship among biology, aesthetics and artistic practice allows…
Specific color sensitivities of prey and predator explain camouflage in different visual systems
2004
In situations of aggressive mimicry, predators adapt their color to that of the substrate on which they sit for hunting, a behavior that is presumed to hide them from prey as well as from their own predators. Females of few crab-spider species encounter such situations when lying on flowers to ambush pollinators. To evaluate the efficiency of spider camouflage on flowers, we measured by spectroradiometry adult female Thomisus onustus and marguerite daisies, Leucanthemum vulgare. We compared chromatic contrast (color used for short-range detection) of each pair of spider and flower to detection thresholds computed in the visual systems of both Hymenopteran prey and passerine bird predator. W…
Forms of gastronomic camouflage: veridiction in the kitchen
2022
In this essay, we analyse the regimes of truth and the forms of culinary camouflage inscribed in some signature dishes by several well-known Italian chefs, whose work is emblematic of the various fictional trends in gastronomy. In doing so, we will keep in mind the so-called semiotic square of veridiction that discursive semiotics has been proposing and using for some time. The analysis reveals how the gastronomic discourse of the Italian haute cousine produces effects of illusion, secrecy, falsehood and truth. The concurrence of these veridiction modes allows for an explicit model which accounts for the various styles of camouflage and thus describes current tendencies in contemporary cuis…
Visual Discrimination of the 17 Plane Symmetry Groups
2011
Within most of the 17 plane symmetry groups, individual symmetry operations act in multiple, nonequivalent ways. This, and the fact that many groups can be realized on the basis of different unit cells and generating regions, poses difficulties for visual discrimination and identification. Because of inherent confounds, only few of the groups can be studied by traditional experimental methodology. The use of an oddity paradigm and specific tiling patterns that camouflage groups in complex textures are recommended as partial remedy to this impasse. In order to prepare readers for an appreciation of the aforementioned issues and to provide a rationale for their investigation, the reporting of…
