Combining textual and visual cues for content-based image retrieval on the World Wide Web

2002

A system is proposed that combines textual and visual statistics in a single index vector for content-based search of a WWW image database. Textual statistics are captured in vector form using latent semantic indexing (LSI) based on text in the containing HTML document. Visual statistics are captured in vector form using color and orientation histograms. By using an integrated approach, it becomes possible to take advantage of possible statistical couplings between the content of the document (latent semantic content) and the contents of images (visual statistics). The combined approach allows improved performance in conducting content-based search. Search performance experiments are report…

Automatic Illustration of Short Texts via Web Images

2015

In this paper we propose a totally unsupervised and automatic illustration method, which aims to find onto the Web a set of images to illustrate the content of an input short text. The text is modelled as a semantic space and a set of relevant keywords is extracted. We compare and discuss different methods to create semantic representations by keyword extraction. Keywords are used to query Google Image Search engine for a list of relevant images. We also extract information from the Web pages that include the retrieved images, to create an Image Semantic Space, which is compared to the Text Semantic Space in order to rank the list of retrieved images. Tests showed that our method achieves v…

Internet of things: why we are not there yet

2014

Twenty-one years past since Weiser's vision of ubiquitous computing (UbiComp) has been written, and it is yet to be fully fulfilled despite of almost all the needed technologies already available. Still, the widespread interest in UbiComp and the results in some of its fields pose a question: why we are not there yet? It seems we miss the 'octopus' head. In this paper, we will try to depict the reasons why we are not there yet, from three different points of view: interaction media, device integration and applications.

Aspetti fiscali dell'immigrazione

2018

Il lavoro attiene agli aspetti fiscali relativi all’acquisizione della residenza fiscale in Italia. Un profilo di indagine riguarda il trattamento dei soggetti che, assumendo una posizione di regolarità nel contesto del lavoro, presentano la dichiarazione dei redditi, vengono tassati e contribuiscono alla previdenza sociale e alle entrate tributarie e, eventualmente. Altro profilo di analisi è la disciplina per cui la leva fiscale determina delle posizioni “agevolate” per incentivare il trasferimento, nel caso di soggetti che possono apportare “ricchezza” implementando la ricerca o con l’investimento di capitali. E’ essenziale il rispetto dei principi costituzionali, a garanzia della consid…

I tamburi a cornice in Sicilia

2015

Le prime attestazioni della presenza del tamburo a cornice in Sicilia risalgono al V secolo a.C. Lo strumento è poi documentato fino ai giorni nostri attraverso raffigu¬razioni, documenti d’archivio, resoconti di viaggiatori stranieri, testi di interesse folklorico e, piuttosto ampiamente, dalla ricerca etnomusicologica moderna, per mezzo di audio-registrazioni e videofilmati. Morfologia, tecniche esecutive, repertori, decorazioni, contesto d’uso dei tamburelli in Sicilia si inscrivono nel più ampio quadro dell’area italiana (centro-meridionale) e mediterranea, ma con alcune specificità, soprattutto nelle tecniche esecutive. Queste, sebbene affini a quelle impiegate in altre regioni italian…

Settore L-ART/08 - EtnomusicologiaFirst evidences of frame drums in Sicily trace back to the V century b.C. Tambourines have been recorded until today by paintings archive documentation observations provided by foreign travellers folkloric literature and quite widely by modern ethnomusicology through audio and video recordings collected on the field. Morphology performance techniques repertoires decorations and social use of tambourines in Sicily refer to the wider context of Italian (central-southern part) and Mediteranean area but with some peculiarities chiefly referring to performance skills. Though similar to the techniques practised in other Italian regions in Sicily we can observe a typical style that can be connected with a common historical background with the Arabic-Islamic world.

Il tarantismo in Sicilia

2017

Il testo prende in esame il complesso di materiali editi e inediti (fonti storiche e archivistiche, documenti musicali, testimonianze etnografiche) che attestano la presenza del tarantismo in Sicilia dalla metà del Seicento alla fine dell’Ottocento. Il caso siciliano viene quindi inquadrato nell’ambito dell’ampia letteratura che ruota intorno al fenomeno, a partire dal classico studio di Ernesto De Martino fino al dibattito sull’interpretazione del fenomeno fra i poli dell’esorcismo e della possessione, dovuto soprattutto all’etnomusicologo francese Gilber Rouget. L’analisi viene quindi estesa alla tradizione dei guaritori dei morsi di serpenti (i ciaràuli), che con il tarantismo condividon…

Settore L-ART/08 - EtnomusicologiaThe text examines published and unpublished materials – such as historical and ethnographic sources archive records and musical documents – which testify the presence of tarantism in Sicily from mid-17th century to the end of the 19th. The Sicilian case is then considered in a wider context of contributions on the theme starting from the ‘classic’ De Martino’work up to the debate on the interpretation of the phenomenon between the poles of exorcism and possession chiefly rased by French ethnomusicologist Gilbert Rouget. The analyses is therefore expanded to the tradition of snakes bites healers (the ciaràuli) which shares with tarantism the spider symbolism and to certain kinds of religious processions characterised by frantic ‘dances’ which suggest elements of functional continuity with tarantism musical-choreutic therapy.

Facebook as a Small World: a topological hypothesis

2011

Facebook is becoming a pervasive entity as its social, cultural and media ramifications grow deep and entrenched in our daily life. Its nature of a complex system of interactions, bearing a strong similarity to networks built through individual choices and systems shaped by evolu- tionary pressure, makes it an interesting target for research. Scale-free Small World networks, recently popularized by Barabasi, are a topological class pertaining to both these domains, whose members have resilience to disruption and short intermediate connections between nodes. In this paper we show that the topological structure of a specific subset of Facebook, gathered using data from a self-report online qu…

Liver and Statins: A Critical Appraisal of the Evidence.

2019

Adverse drug reactions (ADRs) represent an important cause of morbidity and mortality worldwide. Statins are a class of drugs whose main adverse effects are drug-induced liver injury (DILI) and myopathy. Some of these may be predictable, due to their pharmacokinetic and pharmacodynamic properties, while others, unfortunately, are idiosyncratic. Genetic factors may also influence patient susceptibility to DILI and myopathy in the case of statins. This review will first discuss the role of statins in cardiovascular disease treatment and prevention and the underlying mechanisms of action. Furthermore, to explore the susceptibility of statin-induced adverse events such as myopathy and hepatoto…

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…

Settore SECS-P/07 - Economia AziendaleQuality in delivering public services has been recognised as a major issue challenging performance in the public sector as well as the ability to operate effectively and within budget constraints. Empirical findings shown by the literature demonstrate that concrete efforts have been produced towards the evaluation and improvement of satisfaction levels of citizens and other Public Administration’s ‘customers’. However still today this issue portrays many unresolved criticalities particularly concerning the methodological approaches and operative tools to adopt in order to integrate ‘customer satisfaction’ programs with the wider organisational control system in each public administration. This paper adopts a non-conventional view of the ‘customer satisfaction’ concept. This is currently meant as a matter of social reporting or even statistical analysis based on the users’ perceptions on the level of provided services by a given (front office) unit in the public sector. Here an inter-institutional perspective is adopted with a view to map the overall value chain leading to the final product delivered to citizens or the community. Inside this chain tracking the underlying administrative products delivered by back-office units to their ‘internal clients’ in the public administration is recommended as a fundamental step to understand how to improve performance in satisfying citizens’ needs. This should also require a proper link between the administrative units’ goals and performance measures to the desired efficiency and effectiveness of processes leading to the attainment of administrative products providing the basis of the final services delivered to the private sector. Based on first empirical findings from field analysis in the Italian context the paper aims to outline an approach which could assist both politicians and managers to better assess and improve performance according to a customer satisfaction perspective.

The genome-wide structure of two economically important indigenous Sicilian cattle breeds

2014

Genomic technologies, such as highthroughput genotyping based on SNP arrays, provided background information concerning genome structure in domestic animals. The aim of this work was to investigate the genetic structure, the genome-wide estimates of inbreeding, coancestry, effective population size (Ne), and the patterns of linkage disequilibrium (LD) in 2 economically important Sicilian local cattle breeds, Cinisara (CIN) and Modicana (MOD), using the Illumina Bovine SNP50K v2 BeadChip. To understand the genetic relationship and to place both Sicilian breeds in a global context, genotypes from 134 other domesticated bovid breeds were used. Principal component analysis showed that the Sicil…
