TSVD as a Statistical Estimator in the Latent Semantic Analysis Paradigm
2015
The aim of this paper is to present a new point of view that makes it possible to give a statistical interpretation of the traditional latent semantic analysis (LSA) paradigm based on the truncated singular value decomposition (TSVD) technique. We show how the TSVD can be interpreted as a statistical estimator derived from the LSA co-occurrence relationship matrix by mapping probability distributions on Riemanian manifolds. Besides, the quality of the estimator model can be expressed by introducing a figure of merit arising from the Solomonoff approach. This figure of merit takes into account both the adherence to the sample data and the simplicity of the model. In our model, the simplicity…
A Knowledge Management System based on Ontologies
2009
Recently the companies’ interest on a correct knowledge management is grown, more than interest on the mere knowledge itself. In the last few years, several projects have been carried out, with the aim of the development of innovative systems capable of collecting and sharing information. This paper proposes a Knowledge Management System, whose main feature is an ontological knowledge representation. The ontological representation of data allows of specializing the reasoning capabilities and of providing ad hoc behaviors. The system has been tested collecting and using data coming from projects and processes typical of ICT companies, and provides a Document Management System and an Expert S…
Metabolic impact of Partial Volume Correction of [18F]FDG PET-CT oncological studies on the assessment of tumor response to treatment
2014
AIM: The aim of this work is to evaluate the metabolic impact of Partial Volume Correction (PVC) on the measurement of the Standard Uptake Value (SUV) from [18F]FDG PET-CT oncological studies for treatment monitoring purpose. METHODS: Twenty-nine breast cancer patients with bone lesions (42 lesions in total) underwent [18F]FDG PET-CT studies after surgical resection of breast cancer primitives, and before (PET-I) and after (PET-II) chemotherapy and hormone treatment. PVC of bone lesion uptake was performed on the two [18F]FDG PET-CT studies, using a method based on Recovery Coefficients (RC) and on an automatic measurement of lesion metabolic volume. Body-weight average SUV was calculated f…
Computer assisted diagnosis (CAD) in mammography. Comparison of diagnostic accuracy of a new algorithm (Cyclopus(R), Medicad) with two commercial sys…
2008
The study compares the diagnostic accuracy (correct identification of cancer) of a new computer-assisted diagnosis (CAD) system (Cyclopus) with two other commercial systems (R2 and CADx). Cyclopus was tested on a set of 120 mammograms on which the two compared commercial systems had been previously tested. The set consisted of mammograms reported as negative, preceding 31 interval cancers reviewed as screening error or minimal sign, and of 89 verified negative controls randomly selected from the same screening database. Cyclopus sensitivity was 74.1% (R2=54.8%; CADx=41.9%) and was higher for interval cancers reviewed as screening error (90.9%; R2=54.5%; CADx=81.8%) compared with those revie…
Le misure pubbliche di sostegno all'internazionalizzazione delle imprese
2020
Il capitolo analizza gli strumenti di supporto pubblico all'internazionalizzazione delle imprese italiane. In particolare, si esamina il ruolo delle pubbliche amministrazioni e degli istituti nazionali di promozione e il loro supporto tecnico e finanziario in favore delle piccole e medie imprese. The chapter analyzes the public support to the internationalization process of Italian firms. It examines the role of public administrations and national promotional banks and their financial and technical support to small and medium-sized enterprises.
Il delitto di "caporalato" tra diritti minimi della persona e tutela del mercato del lavoro
2020
Il contributo analizza il reato di intermediazione illecita e sfruttamento lavorativo, offrendo un’analisi comparata con il sistema repressivo tedesco. Lo studio si sofferma, in particolare, sui limiti di legittimazione del diritto penale nella punizione dei fatti di “caporalato”, nel tentativo di scongiurare che l’intervento repressivo nelle dinamiche economiche e contrattuali, di natura sinallagmatica, possa assumere una portata tale da porsi in contrasto con il canone della sussidiarietà. A tal fine, si suggerisce una prospettiva ermeneutica che incentri il disvalore penale del reato di cui all’art. 603-bis c.p. sulla lesione dei diritti fondamentali del lavoratore – riconducibili agli a…

La scienza giuridica analitica dalla nascita alla crisi
2020
This paper proposes a critical presentation of the analytical approach to legal science. After an introductory paragraph in which a definition of the notions involved (i.e.: «legal science» and «analytical approach») will be offered and some ambiguities affecting the discourses on legal knowldege will be disentangled, the next paragraphs will be devoted to a survey of the main analytical conceptions of legal science. The focus will be in particular on: (1) Alf Ross’s legal realism and his neo-positivistic approach to legal science; (2) Norberto Bobbio and the Italian analytical legal philosophical school, which firmly tie legal science to language analysis; (3) Herbert Hart and the analytic…

La forza dell’argomento peggiore. La retorica paternalista nell’argomentazione morale e giuridica
2012
In this essay, I shall analyze some arguments advanced for legal paternalism, which are fallacious or rationally insufficient. Some of the worst arguments for legal paternalism. For example, the argument of life’s sacred value, the argument of human dignity or the argument of common good. Why it is important to defend legal antipaternalism against these arguments? Because they are, in spite of their weakness, rhetorically very used in philosophical, ethical, legal, judicial debate. They likely dissimulate other arguments considered less persuasive, like the theological argument or the moral perfectionist argument for legal paternalism
