L'Orchestra di Auschwitz. Inchiesta su Alma Rosé

2023

Il libro è un'inchiesta sulla vita e il tempo di Alma Rosé (1906-1944), nipote di Gustav Mahler, debuttante e ragazza alla moda fra gli anni Venti e Trenta del secolo scorso, violinista il cui talento matura – paradossalmente – mentre l’ombra del nazismo si dispiega sull’Europa e infine direttrice dell’orchestra di Auschwitz. in un’epoca in cui la carriera del direttore d’orchestra era declinata soltanto al maschile. Giunta ad Auschwitz nell’estate 1943 e assegnata dapprima al Block degli esperimenti medici, Alma riuscì in breve tempo a diventare – nel piccolo mondo terribile del Lager – una specie di celebrità: ed è in quelle tenebre, d’altronde, che si svolge l’atto finale del dramma, oss…

Settore L-ART/07 - Musicologia E Storia Della MusicaThe book is an investigation into the life and time of Alma Rosé (1906-1944) granddaughter of Gustav Mahler debutant and fashionable girl between the twenties and thirties of the last century violinist whose talent matures – paradoxically – while the shadow of Nazism unfolds over Europe and finally director of the Auschwitz orchestra. at a time when the career of the conductor was declined only to men. Arriving at Auschwitz in the summer of 1943 and first assigned to the Block of medical experiments Alma managed in a short time to become – in the small terrible world of the Lager – a kind of celebrity: and it is in those darknesss moreover that the final act of the drama takes place that is the mysterious death and without a reason of the protagonist.

'L'ADAMO, OVVERO IL MONDO CREATO' DI TOMMASO CAMPAILLA. UN CONTRIBUTO AL RINNOVAMENTO DELLA CULTURA SCIENTIFICA E LETTERARIA IN SICILIA

2022

L’articolo analizza L’Adamo, ovvero il Mondo creato, poema scientifico-filosofico di Tommaso Campailla (1668-1740), accademico modicano, che partecipò con i suoi esperimenti scientifici e la sua opera letteraria a diffondere la filosofia cartesiana e le nuove mirabili scoperte in ogni campo del sapere. Nel poema Campailla ricorre al motivo tradizionale del viaggio di conoscenza per squadernare al Primo Uomo, Adamo, le straordinarie meraviglie della creazione, tentando una sintesi tra istanze scientifiche e nuove direttrici della poesia settecentesca.

Settore L-FIL-LET/10 - Letteratura ItalianaThe article analyzes L'Adamo ovvero il Mondo creato a scientific-philosophical poem by Tommaso Campailla (1668-1740) a Modican academic who participated with his scientific experiments and his literary work to spread the Cartesian philosophy and the new wonderful discoveries in every field of knowledge. In his poem Campailla he uses the traditional motif of the journey of knowledge to square the extraordinary wonders of creation to the First Man Adam attempting a synthesis between scientific instances and new directions of eighteenth-century poetry.

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Computer experiments combined with physical Experiments: two experiences in product development

2012

Physical experiments in industrial product development are often very expensive but also necessary sometimes even for safety reasons (think about the crash tests in the automotive industry conducted with new and completely equipped vehicles). Therefore there is a pressing need to reduce this cost as much as possible. Computer experiments may be a viable solution provided that their results are reliable as much as the physical ones. In most of the cases, computer experiments are opportunely combined with physical experiments and the recipe of such mix is interesting itself. In this presentation we will show two cases of combination of physical and computer experiments in product development.…

Search for Isovector Valence-Shell Excitations in 140 Nd and 142 Sm via Coulomb excitation reactions of radioactive ion beams

2018

Projectile Coulomb excitation experiments were performed at HIE-ISOLDE at CERN with the radioactive ion beams of 140Nd and 142Sm. Ions with an energy of 4:62 MeV/A were impinging on a 1.45 mg/cm2 thick 208Pb target. The γ-rays depopulating the Coulomb-excited states were recorded by the HPGe-array MINIBALL and scattered particles were detected by a double-sided silicon strip detector. Experimental intensities were used for the determination of electromagnetic transition matrix elements. A preliminary result of the B(M1; 2+3 → 2+1) of 140Nd and an upper limit for the case of 142Sm are revealing the main fragments of the proton-neutron mixed-symmetry 2+1;ms states.

Advanced Statistical Tools for Six Sigma and other Industrial Applications

Six Sigma is a methodological approach and philosophy for quality improvement in operations management; its main objectives are identifying and removing the causes of defects, and minimizing variability in manufacturing and business processes. To do so, Six Sigma combines managerial and statistical tools, with the creation of a dedicated organizational structure. In this doctoral thesis and the three years of study and research, we have had the purpose to advance the potential applications of the methodology and its tools; with a specific attention on issues and challenges that typically prevent the realization of the expected financial and operational gains that a company pursue in applyin…

A new mathematical approach for the estimation of the AUC and its variability under different experimental designs in preclinical studies

2011

The aim of the present work was to develop a new mathematical method for estimating the area under the curve (AUC) and its variability that could be applied in different preclinical experimental designs and amenable to be implemented in standard calculation worksheets. In order to assess the usefulness of the new approach, different experimental scenarios were studied and the results were compared with those obtained with commonly used software: WinNonlin® and Phoenix WinNonlin®. The results do not show statistical differences among the AUC values obtained by both procedures, but the new method appears to be a better estimator of the AUC standard error, measured as the coverage of 95% confi…
