Continuum: A spatiotemporal data model to represent and qualify filiation relationships
2013
International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…

Understanding Urban Fabric with the OH_FET model based on Social Use, Space and Time
2008
The proposed principle for understanding the urban fabric is based on considering the town as a set of complex objects, taking a systemic approach. The town system used to study the urban fabric over large time spans is composed of three sub-systems relating to historical objects from the level of the excavation to that of the former urban space: function (social use), space (location, surface area and morphology) and time (dating, duration and chronology). The historical object is the analytical unit of the space studied. It is the Cartesian product of the three sets, Social use, Space and Time, from which it stems. On the basis of this process, the Historical Object (OH) is broken down in…
Collaborative Design Rational and Social Creativity in Cultures of Participation
2011
The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…
Forme necessarie dell’abitare: il ruolo dello spazio pubblico nei contesti informali di Bogotá e Medellín
2015
Gli spazi collettivi rappresentano un beneficio per la comunità, specialmente in quei contesti urbani “informali”, manifestazione fisica del bisogno primordiale dell’abitare. La straordinaria e recente rigenerazione urbana e sociale conquistata dalle città colombiane di Bogotá e Medellín, è un notevole esempio di strategie politiche e progettuali innovative, risultato delle azioni congiunte di politici, professionisti e cittadinanza, che fondano le proprie radici sul riconoscimento del ruolo sociale ed urbano dello spazio pubblico, elemento ristrutturante il tessuto urbano ed umano. La progettazione di nuovi spazi collettivi nei contesti urbani più fragili, più marginali ed abbandonati dell…
La produzione dello spazio democratico per il soddisfacimento del bene comune
2015
Nella storia della città lo spazio pubblico e le attrezzature collettive rappresentano da sempre luoghi di coesione, interscambio, relazione, condivisione e cooperazione per l’uomo, il quale manifesta il bisogno di abitare un luogo in cui possa relazionarsi con gli altri, formando una comunità ed una vita pubblica. Gli spazi collettivi rappresentano pertanto un beneficio per la comunità, in quanto diaframmi tra la sfera pubblica e la sfera privata, luoghi di uguaglianza e di democrazia, ove si alimenta il 'capitale sociale' e si annulla l’esclusione sociale e spaziale, a favore di un interscambio socio-culturale tra individui diversi. Nelle città globalizzate la disuguaglianza nella distrib…
Interspecific information on predation risk affects nest site choice in a passerine bird
2018
Abstract Background Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has been suggested to drive niche segregation and local coexistence of species. Interspecific social information use may, in turn, result in copying or rejection of heterospecific niche characteristics and thus affect realized niche overlap between species. We tested experimentally whether a migratory bird, the pied flycatcher Ficedula hypoleuca, collects information about nest predation risk from indirect cues of predators visiting nests of heterospecific birds. Furthermore, we investigated whether the migratory birds can associate such information w…
Growth and Physiological Performance of a Coastal Species Trifolium fragiferum as Affected by a Coexistence with Trifolium repens, NaCl Treatment and…
2021
The aim of the present study was to analyze the growth and physiological performance of two coexisting species, Trifolium fragiferum, and Trifolium repens, under the effect of NaCl and rhizobial symbiosis. Seeds of T. fragiferum and T. repens were collected from populations in the wild, and plants were cultivated in an automated greenhouse, two plants per container. Three basic types of planting were performed: (1) both plants were T. fragiferum (single species), (2) one T. fragiferum and one T. repens (species coexistence), (3) both plants were T. repens (single species). For every basic type, three subtypes were made: (1) non-inoculated, (2) inoculated with rhizobia taken from T. fargifer…
Observed Fitness May Affect Niche Overlap in Competing Species via Selective Social Information Use
2013
Social information transmission is important because it enables horizontal spread of behaviors, not only between conspecifics but also between individuals of different species. Because interspecific social information use is expected to take place among species with similar resource needs, it may have major consequences for the emergence of local adaptations, resource sharing, and community organization. Social information use is expected to be selective, but the conditions promoting it in an interspecific context are not well known. Here, we experimentally test whether pied flycatchers (Ficedula hypoleuca) use the clutch size of great tits (Parus major) in determining the quality of the ob…
Understanding the impact of digital on performing arts: a systematic literature review proposal
2023
Digital technologies have profoundly changed the cultural and creative industries. Due to the intrinsic characteristics of the performing arts sector, this digital transition has had a later impact on it. However, it has accelerated since the Covid-19 pandemic, forcing organizations to digitally transform themselves to keep in touch with their audience(s). Now that this crisis is over, many strategic and operational questions still remain unanswered. This research proposes a systematic literature review in order to establish the state of the art of the research on digitalization of the performing arts sector and to highlight the main research avenues to be explored.
