    Applied Machine Learning for Health Informatics: Human Motion Analysis and Affective Computing Application

    No full text
    Il monitoraggio della qualità della vita e del benessere della persona rappresenta una sfida aperta nello scenario sanitario. La necessità di risolvere questo task nella nuova era dell'Intelligenza Artificiale porta all’applicazione di metodi dal campo del machine learning. Gli obiettivi e i contributi di questa tesi riflettono le attività di ricerca svolte (i) nell’ambito dell’analisi del movimento: valutazione e monitoraggio automatico del movimento umano durante la riabilitazione fisica, e (ii) nell’ambito dell’affective computing: stima dello stato affettivo del soggetto. Nel primo tema il candidato presenta un algoritmo in grado di estrarre le caratteristiche di movimento clinicamente rilevanti dalle traiettorie dello skeleton acquisite da un sensore RGBD, e fornire un punteggio sulla prestazione del soggetto. L'approccio proposto si basa su regole derivate da indicazioni cliniche e su un algoritmo di machine learning (i.e., Hidden Semi-Markov Model). L'affidabilità dell'approccio proposto è studiata su un dataset collezionato dal candidato rispetto ad un algoritmo gold standard e alla valutazione clinica. I risultati sostengono l'uso della metodologia proposta per la valutazione quantitativa delle prestazioni motorie durante la riabilitazione fisica. Nel secondo topic il candidato propone l’applicazione del framework di Multiple Instance Learning per l'apprendimento della risposta emotiva in presenza di label continui ed ambigui. Questa varaibilità è spesso presente nella risposta affettiva ad uno stimolo esterno (e.g., interazione multimediale). L'affidabilità dell'approccio di Multiple Instance Learning è indagata su un database di benchmark e un dataset più vicino alle problematiche del mondo reale acquisito dal candidato. I risultati ottenuti evidenziano come la metodologia proposta è consistente per la stima dello stato affettivo.The monitoring of the quality of life and the subject's well-being represent an open challenge in the healthcare scenario. The emergence of solving this task in the new era of Artificial Intelligence leads to the application of methods in the machine learning field. The objectives and the contributions of this thesis reflect the research activities performed on the topics of (i) human motion analysis: the automatic monitoring and assessment of human movement during physical rehabilitation and (ii) affective computing: the inferring of the affective state of the subject. In the first topic, the author presents an algorithm able to extract clinically relevant motion features from the RGB-D visual skeleton joints input and provide a related score about subject’s performance. The proposed approach is respectively based on rules derived by clinician suggestions and machine learning algorithm (i.e., Hidden Semi Markov Model). The reliability of the proposed approach is tested over a dataset collected by the author and with respect to a gold standard algorithm and with respect to the clinical assessment. The results support the use of the proposed methodology for quantitatively assessing motor performance during a physical rehabilitation. In the second topic, the author proposes the application of a Multiple Instance Learning (MIL) framework for learning emotional response in presence of continuous and ambiguous labels. This is often the case with affective response to external stimuli (e.g., multimedia interaction). The reliability of the MIL approach is investigated over a benchmark database and one dataset closer to real-world problematic collected by the author. The obtained results point out how the applied methodology is consistent for predicting the human affective response

    Agricultural Genetics and Plant Breeding in Early Twentieth-Century Italy

    No full text
    This thesis is about plant breeding in Early 20th-Century Italy. The stories of the two most prominent Italian plant-breeders of the time, Nazareno Strampelli and Francesco Todaro, are used to explore a fragment of the often-neglected history of Italian agricultural research. While Italy was not at the forefront of agricultural innovation, research programs aimed at varietal innovation did emerge in the country, along with an early diffusion of Mendelism. Using philosophical as well as historical analysis, plant breeding is analysed throughout this thesis as a process: a sequence of steps that lays on practical skills and theoretical assumptions, acting on various elements of production. Systematic plant-breeding programs in Italy started from small individual efforts, attracting more and more resources until they became a crucial part of the fascist regime's infamous agricultural policy. Hybrid varieties developed in the early 20th century survived World War II and are now ancestors of the varieties that are still cultivated today. Despite this relevance, the history of Italian wheat hybrids is today largely forgotten: this thesis is an effort to re-evaluate a part of it. The research did allow previously unknown or neglected facts to emerge, giving a new perspective on the infamous alliance between plant-breeding programs and the fascist regime. This thesis undertakes an analysis of Italian plant-breeding programs as processes. Those processes had a practical as well as a theoretical side, and involved various elements of production. Although a complete history of Italian plant breeding still remains to be written, the Italian case can now be considered along with the other case-studies that other scholars have developed in the history of plant breeding. The hope is that this historical and philosophical analysis will contribute to the on-going effort to understand the history of plants

    Aspetti critici negli studi clinici: problemi di metodo e applicazione

    No full text
    A clinical study is useful to clarify some planned questions and it follows a well defined scheme (the study design). This PhD thesis has been divided in five main sections following a scheme guiding the reader in the analysis of critical aspects it's possible to find, first in data management, then in the study design and during the development and the final phases of a clinical study. Section A, Problems in database management, proposes a chapter about Record Linkage and a second chapter about Missing Values. Record Linkage consists in a series of statistical and data processing techniques for data integration and for the union of more datasets on the basis of patients' identifying variables. The problem of missing values is frequently present in a study: when a database contains missing values it's possible to turn to specific systems useful to calculate a suitable value for the unit without information, through statistical programs. In section B, Study design, first clinical trials are analysed, then surveys are described and divided in cohort studies and case-control studies. In a cohort study (also called follow-up or prospective study) one or more groups of subjects are defined in accordance with the exposure to risk factors for one or more diseases, or not. Subjects are prospectively followed to study the disease(s) incidence and to observe if the disease(s) is(are) correlated with the etiological factors. A case-control study (or retrospective study) provides a research strategy to investigate possible factors preventing or causing a particular disease. The method implies a comparison between patients with the disease (cases) and a control group (healthy subjects). The comparison ends to find out factors which can be different in the two groups, explaining the presence of the disease in patients. Section C concerns Variables treatment and Outcome variable classifications. In the first part, types of variables, their measurement scales, their reduction in indicators and their transformations are analysed. In the second part the classifications of the outcome variable is described. These classifications may regard a specific disease (ICD IX and X), the patient's symptoms (ICD) or a disease effect, i.e. an impairment, a disability or a handicap (ICIDH and ICF). Sections D and E deal with choice of the multivariate analysis method. Section D aims to give a synthesis of the main analysis methods, dividing them in accordance with the variables symmetry. If there is a distinction between outcome variable and covariates, a multiple regression (stepwise or logistic) analysis method is suggested; discriminant analysis is useful if there are more outcome variables. If variables are all on the same level, factors analysis, principal components analysis, correspondences analysis and cluster analysis are proposed in conformity with the specific analysis aims. In section E logistic regression analysis is developed, pointing out the main aspects and considering the conditional logistic regression analysis for a Matched Case-Control Study design. Every chapter is organized in two parts: in the first one a synthesis of theory and practical methods are given to explain how literature deals with the specific problem in a clinical study; in the second one a specific application is presented to show how the author solved the methodology problems in a particular clinical-genetic study carried out at the Children's Hospital of Oulu University - Finland. In this Institute a substantial work on a preterm infants database creation has been performed. The database collected all the clinical and genetic information about preterm infants born in one of the three main hospitals in Northern-central Finland, Oulu, Tampere and Seinäjoki. Through this final database containing all patients from the three hospitals, a clinical-genetic case-control study (match 1-1) on the association between Respiratory Distress Syndrome (RDS) and single nucleotide polymorphisms (SNPs) has been carried out using a conditional logistic regression analysis. The project was directed by Prof. M. Hallman

    An Unknown Italian Translation of Marulić’s Quinquaginta parabolę

    No full text
    While undertaking researches in Padua, the author found in the library of the Archiepiscopal Seminary (Biblioteca del Seminario vescovile) a previously totally unknown Italian translation of Marulić’s Quinquaginta parabolae, printed in Treviso, without any indication of the year: Cinquanta parabole di Marco Marulo, dal Latino al Volgare trasportate dall’abate Giuseppe Tacini. In Treviso, presso Giulio Trento (88 pages). The only previously known Italian translation is of 1881, published in Genoa, and entitled Cinquanta parabole di Marco Marullo, liberamente tradotte dal prof. Giuseppe Gazzino. This newly found version is beyond any doubt earlier; although no year is given for the printing, the details about the printer (Giulio Trento, 1732-1813) entail the conclusion that it was published at the end of the 18th or beginning of the 19th century

    Commentary on art. 104 and art. 104 bis of the consolidated finance act (defensive measures in take-overs)

    No full text
    My rate for this contribution is 2 star. The piece, written in Italian, has been published on a peer-reviewed law commentary, edited by a full professor (Giuseppe Fauceglia) of the University of Salerno and published by Giappichelli, one of the most prestigious law publishers in Italy. The book is part of a law encyclopaedia (Le nuove leggi del diritto dell'economia - The new laws in law and economics), directed by Prof. Sandulli and Santoro. The commentary provides a lengthy and in-depth analysis in the matter of the defensive measures in the take-over, both in Italy and in the UK as a result of the implementation of the EU directive 25/2004. The research method adopted is based on the revision of both the primary and secondary sources, existing in the two legislations concerned (Italy and the UK) and its discussion in a critical way. The article manages to corroborate, for the first time, the theory of possible flaws in the way the takeover directive has been implemented in Italy in the matter of the defensive measures.The article is of international standing, also because written by a British academic in a position to critically assess and evaluate a jurisdiction of international magnitude (the Italian), in connection to the EU over-layer, with a comparison to the British legislation. In this respect, the article does not have precedents, in terms of effectiveness of the final stances it managed to prop up.The author, for this specific article, has already been cited up to 50 times in law journals and other edited books.<br/
