Le genre est-il un paradoxe? La transgression générique dans « 53 jours » de Georges Perec

2009

The Oulipian genre is characterized by the transgression of the canonical hierarchy of genres, imposing a set of constraints and writing techniques as the principles for the organization of the literary space. This hybrid generic "form", designated with the neologism "Oulipogenre", which subverts the traditional notion of genre. The Oulipogenre establishes a horizon of kinetic suspension, depriving the reader of identification and decodification of the genre. Founded on interpretative instability, George Perec's «53 jours» necessitates the acceptance of destabilization, of the cognitive "aberration" of the text. Le « genre » oulipien se signale par la transgression de la hiérarchisation can…

Fantastic morphologies: animal form between mythology and Evo-Devo

2020

Since ancient times, man has shown a genuine passion for the recombination of visual elements in unusual and extraordinary forms; but, if the ancients admitted the existence of mythological creatures, today we are fully aware that their existence is limited to the ontological domain of the “merely thinkable” because imaginary beings are irreconcilable with physical and biological laws. In this article I try to elucidate what differentiates from a morphological point of view the imaginary beings described by the pens of poets (such as Sphinx, mermaids and centaurs) from bizarre but existing animals (i.e. the small South American Axolotl, the Yeti Crab, etc.) or from some specimens belonging …

I vincoli della trasformazione: riflessioni sulla metamorfosi tra letteratura, filosofia e biologia

2019

Per sopravvivere gli esseri viventi sono costretto a modificarsi di continuo, adattandosi all’ambiente e al variare delle circostanze. In questa costante alterazione formale come si conciliano identità e mutamento? Come può l’individuo preservarsi dal totale dissolvimento in qualcos’altro? Questi sono solo alcuni dei quesiti che nei secoli hanno spinto studiosi di Morfologia, Estetica e Biologia a indagare le trasformazioni organiche. Nella presente trattazione cercheremo di chiarire le somiglianze e le differenze fra alcuni concetti chiave del vocabolario della metamorfosi (trasformazione, permutazione, vincolo, libertà di cambiamento, modularità organica) adottando un approccio multidisci…

Interpreting Connexive Principles in Coherence-Based Probability Logic

2021

We present probabilistic approaches to check the validity of selected connexive principles within the setting of coherence. Connexive logics emerged from the intuition that conditionals of the form If \(\mathord {\thicksim }A\), then A, should not hold, since the conditional’s antecedent \(\mathord {\thicksim }A\) contradicts its consequent A. Our approach covers this intuition by observing that for an event A the only coherent probability assessment on the conditional event \(A|\bar{A}\) is \(p(A|\bar{A})=0\). Moreover, connexive logics aim to capture the intuition that conditionals should express some “connection” between the antecedent and the consequent or, in terms of inferences, valid…

The recourse to trade credit by Italian firms during the crisis

rade credit, for many firms, is an essential tool for financing growth. Trade credit indicates a practise to buy goods or services on account without making immediate cash payment. Although trade credit is an important source of funds for small businesses, little has been known about the reasons business customers use it. Economists have linked the use of trade credit to transaction and financing motive. The use of trade credit because credit from other sources, particularly from financial institutions, is limited during recession periods represents a reasonable motive. In order to verify if Italian firms faced to credit restrictions by recurring more intensively to trade credit, we examine…

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.

A mutual GrabCut method to solve co-segmentation

2013

Publised version of an article from the journal:Eurasip Journal on Image and Video Processing. Also available on SpringerLink:http://dx.doi.org/10.1186/1687-5281-2013-20. Open Access Co-segmentation aims at segmenting common objects from a group of images. Markov random field (MRF) has been widely used to solve co-segmentation, which introduces a global constraint to make the foreground similar to each other. However, it is difficult to minimize the new model. In this paper, we propose a new Markov random field-based co-segmentation model to solve co-segmentation problem without minimization problem. In our model, foreground similarity constraint is added into the unary term of MRF model ra…

The cost of protection racket in Sicily

2008

The purpose of this paper is to estimate the current cost of protection rackets in Sicily. By means of a database constructed on judicial evidence, it has been possible to come up with an estimate of the average and total costs of the protection-money system, as well as finding out in which sectors of economic activity and in which provinces is most pervasive. The average monthly payment is approximately 600 euros per business, with stronger effects in those areas with a relatively more traditional economic structure. As a whole, in monetary terms, the protection racket in Sicily accounts for over 1.4% of gross regional product. Finally, the paper supports the hypothesis that in most cases,…

Comparing biological classifications of freshwater phytoplankton: a case study from South China

2012

The use of ecological classification systems is becoming more and more widely used when studying phytoplankton. Grouping phytoplankton species into ecologically coherent groups allow to reduce redundancy and in this way, to handle a minor number of biological variables when investigating the ecological status of aquatic ecosystems. Three ecological classifications are mostly used when freshwater phytoplankton is studied: functional groups or coda, morpho-functional groups (MFGs) and morphology-based functional groups (MBFGs). In this study, these three ecological classifications were comparatively used along with two taxonomic classifications based on species and genera to analyse phytoplan…
