An amalgamation property for metric spaces
2016
In this paper we show that sufficiently similar finite metric spaces can be amalgamated so that the distance between them is sufficiently small.
AAA: Aulas de aprendizaje activo
2021
Para promover el aprendizaje de los alumnos, algunas universidades están creando espacios de aprendizaje activo que reemplazan a las aulas tradicionales de clase magistral. En la Universitat Jaume I de Castelló se han creado dos aulas (denominadas TEAM) para potenciar el aprendizaje cooperativo. Este trabajo tiene como objetivo describir el aula TEAM, explicar dos proyectos complementarios dirigidos a mejorar su funcionamiento y presentar los resultados de la primera de sus tres fases. To promote student learning, some universities are creating active learning spaces that replace traditional master class classrooms. In Universitat Jaume I de Castelló, two classrooms (called TEAM) have been …
Fixed point theorems for α-set-valued quasi-contractions in b-metric spaces
2015
Recently, Samet et al. [B. Samet, C. Vetro and P. Vetro, Fixed point theorems for alpha-psi-contractive type mappings, Nonlinear Anal., 75 (2012), 2154-2165] introduced the notion of alpha-psi-contractive mappings and established some fixed point results in the setting of complete metric spaces. In this paper, we introduce the notions of alpha-set-valued contraction and alpha-set-valued quasi-contraction and we give some fixed point theorems for such classes of mappings in the setting of b-metric spaces and ordered b-metric spaces. The presented theorems extend, unify and generalize several well-known comparable results in the existing literature.

In this paper, the author studies the unitary representations of the braid group and the geometric structures on moduli space that arise via the Hodge theory of cyclic branched coverings of P^1. In particular, the author is interested in the classification of certain arithmetic subgroups of U(r, s) which envelop the image of the braid group. The author investigates their connections with complex reflection groups, Teichm\"{u}lller curves, ergodic theory and problems in surface topology.
A NEW DIALETICS CENTRE/PERIPHERY: CONSUMPTION PATTERNS AND PRACTICES IN THE SUBURBAN AREAS
2014
This paper deals with the analysis of current changes which have been recently shaping unprecedented urban structures in some suburban areas, due to the emerging of new consumptions spaces. In particular, the work aims at highlighting the effect of urban sprawl on the main Sicilian metropolitan areas, also moulded by the diffusion of the suburban retailing formats, in order to evaluate to what extent these dynamics have been contributing to the configuration of new urban landscapes and unprecedented socio-economic structures, not to mention the support in the process of containing social and economic marginalisation.
Wymiar społeczny w projektowaniu zrównoważonego rozwoju miasta
2020
Artykuł zawiera rozważania na temat związku społecznie zrównoważonego rozwoju miasta i projektowania urbanistycznego. Wyrażając przekonanie, że równowaga społeczna jest jednym z podstawowych elementów zrównoważonego rozwoju miasta, autor zaznacza jednocześnie, że projektowanie urbanistyczne ukierunkowane na realizację celów zrównoważonego rozwoju może nie uzyskać akceptacji społecznej. W artykule wskazano na różne podejścia do zdefiniowania społecznie zrównoważonego rozwoju obszarów miejskich. Starano się również określić, które elementy projektowania urbanistycznego mają szczególne znaczenie dla jego realizacji, zwracając uwagę na przestrzenną formę miasta i kwestię dostępności przestrzeni…
Perceptual Anchoring via Conceptual Spaces
2004
Perceptual anchoring is the problem of creating and maintaining in time the connection between symbols and sensor data that refer to the same physical objects. This is one of the facets of the general problem of integrating symbolic and non-symbolic processes in an intelligent system. Gärdenfors’ conceptual spaces provide a geometric treatment of knowledge which bridges the gap between the symbolic and subsymbolic approaches. As such, they can be used for the study of the anchoring problem. In this paper, we propose a computational framework for anchoring based on conceptual spaces. Our framework exploits the geometric structure of conceptual spaces for many of the crucial tasks of anchorin…
La préservation de l'environnement nocturne : les enjeux d'une controverse sociotechnique
2013
This communication explains the birth of an environmental problem, light pollution, understood as a socio-technical controversy. Over forty years, in support of the actor-network approach, it traces the conditions of its emergence, transformation and dissemination to local, national and transnational levels, and through various professional disciplines. Schematically, "environmentalists" uphold a holistic approach of "nocturnité" and define artificial light as a pollutant. Facing them, the "technicist" defend a segmented approach and define artificial light as a nuisance. The implementation of this controversy on the political agenda leads to institutional decisions that grasp it with diffi…
(Ré)concilier éclairage urbain et environnement nocturne : les enjeux d’une controverse sociotechnique
2014
International audience; Our paper explains the birth of an environmental problem, i.e. light pollution, viewed as a socio-technical controversy. Supported by the actor-network approach, it traces over forty years the conditions of its emergence, transformation and dissemination to local, national and transnational levels and through various professional disciplines. Schematically, “environmentalists” uphold a holistic approach of “nocturnality” and define artificial light as a pollutant. Facing them, the “technicist” defends a segmented approach and defines artificial light as a nuisance. The introduction of this controversy into the political agenda leads to institutional decisions that gr…
Gestión del cuerpo y planificación urbana: Desplazamiento de significado en la reivención de cuepos y ciudades
2020
Contemporary cities have administrations increasingly marked by urban planning guidelines that are guided by business and marketing and, to attract investments and tourists, implement strategies that aim to homogenize, spectacularize and control urban space. However, other experiences in the city potentially build new meaning to it, which would escape those strategically planned, creating alternative possibilities of uses, diverging from the way thar are predicted and proposed by the governmental power in their urban marketing strategies. The article discusses how the occupation of urban spaces by transvestites for prostitution may imply reflections on the role of norms of gender in the (re…
