Features for Text Comparison
2008
The main purpose of this paper is to deliver appropriate tool to find similarities between texts. The area of interest covers comparing large amount of different texts grouped in various areas of knowledge. Similarity is defined as distance between two texts and as this the measure may be calculated as the set of parameters based on features.
A Novel Multidimensional Scaling Technique for Mapping Word-Of-Mouth Discussions
2009
The techniques which utilize Multidimensional Scaling (MDS) as a fundamental statistical tool have been well developed since the late 1970’s. In this paper we show how anMDS scheme can be enhanced by incorporating into it a Stochastic Point Location (SPL) strategy (one which optimizes the former’s gradient descent learning phase) and a new Stress function. The enhanced method, referred to as MDS SPL, has been used in conjunction with a combination of the TF-IDF and Cosine Similarities on a very noisy Word-Of-Mouth (WoM) discussion set consisting of postings concerning mobile phones, yielding extremely satisfying results.
Political Consumerism and Food Community Networks
2011
European society, with its steadily increased welfare levels, is not only concerned about food (safety, prices), but also on other aspects such as biodiversity loss, landscape degradation, pollution of water, soil and atmosphere. To a large extent these concerns can be translated into a wider concept named sustainable development defined as a normative concept by Morgan and Sonnino (2008). Sustainability in the food chain means approaching a new emerging vision of a sustainable agro-food system introducing an institutional dimension to take into account. Among different attempts to conjugate such concepts, there is one that is taking place in many Regions of Italy. In the last years spontan…

Trophic and spatial complementarity on seed dispersal services by birds, wild mammals, and cattle in a Mediterranean woodland pasture
2021
Made available in DSpace on 2022-05-01T09:47:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-11-01 Università degli Studi di Palermo CYTED Ciencia y Tecnología para el Desarrollo Federación Española de Enfermedades Raras Most earth surfaces have undergone intensive land-use changes, creating habitat mosaics. Seed dispersal by animals is a crucial process in such mosaics, but community-wide studies comparing the functional complementarity and response to man-imposed habitat heterogeneity are rare. Here, we investigate the trophic and spatial seed dispersal networks underpinning a strong, woody vegetation expansion over a pastureland inside the largest forest remnant in western Sici…
Extensive backthrusting features in the northern Sicily continental margin highlight a late collisional stage of the Sicilian Fold and Thrust Belt
2016
Backthrusting, nappe refolding, and normal faulting frequently characterize late collisional stage of an orogen. Shortening driven by backthrusting is widely reported in the Alpine orogen, and it has been proposed to be responsible for the increase of subsidence. Moreover delamination and backthrusting has been considered as related to subcritical condition of a Coulomb-type accretional wedge (Torres Carbonell et al., 2011). The Sicilian Fold and Thrust Belt (SFTB) was characterized by a three-stage evolution during the last 15 My: two main shortening events generated and developed at different structural levels (shallow- and deep-seated thrusts in thinskinned thrust-model) and different ti…
Architetture di Culotta e Leone nel centro storico di Cefalù: piano, progetto e attuazione
2016
Per gran parte del Novecento gli interventi architettonici nei contesti storici sono stati ricondotti entro i poli della conservazione e trasformazione. In Italia gli anni Ottanta hanno segnato una tappa decisiva nel percorso teorico, metodologico e operativo verso l’approccio richiesto dalle attuali e futuribili condizioni delle aree urbane di antico impianto: guidato da strategie a lungo termine; più responsabile; multiscalare e includente l’intera città contemporanea. L’esperienza di Culotta e Leone nel centro storico di Cefalù, pur costituendo un unicum per il loro ancoramento alla realtà sociale del luogo, fornisce un interessante esempio di continuità tra piano, progetto e attuaz…
Building community spaces: Processes and actions In the City of Mercato Ballarò in Palermo
2022
The rediscovery of the cultural value of a project, the creation of new imagery in marginal places and the new aesthetics of temporality are some of the emerging issues in the city of crisis which are measured through processes of active involvement in community relations. There are many cities that have recognised urban markets as an integral part of local economies, with great benefits also at cultural and social levels. The hypothesis of triggering regenerative processes in the urban and social fabric in the unstable urban market context is the foundation of this research-action contribution developed through active relationships with public entities, associations and citizens. The syste…
(Ri)costruire spazi di comunità. Progetto-azione nella città del mercato Ballarò a Palermo
2022
The rediscovery of the cultural value of the project, the creation of new imaginaries in marginal places and the new aesthetics of temporality are some of the emerging issues in the city of crisis in Italy that are measured through processes of active involvement of inhabitants, associations and institutions. The contribution first proposes an analysis of the potential of public space through a research-action with a high social content in the urban fabric of the Ballarò market in Palermo. Subsequently, the research returns a multidisciplinary perspective on the interpretative models of public space to propose new imaginaries. Themes related to social inclusion, community participation proc…
Palermo si cura. Pratiche culturali di mutuo soccorso come risposta alle fragilità della città (post)pandemica
2023
In un quadro di riferimento in cui la crisi è globalizzata ma diseguale e in mancanza di un sistema di welfare capace di rispondere alle urgenze dei contesti e dei gruppi sociali più marginalizzati, una risposta ai nuovi bisogni sociali ed individuali è stata offerta da reti solidali e da pratiche di mobilitazione dal basso che svolgono un ruolo di agency territoriale, spesso indipendentemente o in assenza di Istituzioni. Nel contesto palermitano un impegno agito da una pluralità di soggetti culturali già attivi sul territorio, riuniti in un’assemblea pubblica (Palermo si cura), durante il periodo del primo lockdown hanno dato vita ad azioni di mutuo soccorso per rispondere all’emergenza ec…
