A procedure to mathematically amend possible thickness disuniformities in gel-layer dosimetry
The continuous development of conformal radiotherapies requires a corresponding improvement of dosimetric techniques. Fricke gel-layer dosimetry, coupled with a suitably developed software, has proven to be a reliable technique for 3D absorbed dose distribution verification. The method is based on the evaluation of the light transmitted by gel-layers due to the fact that th optical density difference between irradiated and non irraddiated dosimeters is proportional to the absorbed dose. Measurement are performed by means of a planar illumination source and a computer-controlled CCD camera. Recently, adoption of gel layers with increased superficial dimensions has evidenced a possible thickness disuniformity of layers, thus introducing a new source of measurement inaccuracy. In this work, a method to mathematically amend this possible source of error is proposed. Dose profiles along the central axis of phantoms irradiated with X-ray therapy and Boron Neutron Capture Therapy fields, obtained with and without the application of the proposed correction procedure, were compared with ionization chamber measurements and Monte Carlo simulations, respectively. The obtained results show a good reliability of the proposed procedure

Michelstaedter Carlo
Pressoché tutti gli scritti di Carlo Michelstaedter furono pubblicati solo dopo il suo sucidio, prima dagli amici V. Arangio-Ruiz e G. Chiavacci e, più recentemente, in molte altre edizioni che l’hanno reso uno dei filosofi italiani più letti e studiati del primo Novecento. La sua riflessione si radica in un contesto mitteleuropeo attraversato da crisi esistenziali e influenze filosofiche che spaziano da Parmenide e Eraclito fino a Ibsen e Nietzsche. Egli critica la “rettorica”, che rappresenta la sottomissione agli interessi egoistici e alle strutture di potere; alla retorica egli contrappone il “benificio”, inteso come apertura disinteressata all’altro, e la “persuasione” quale aspetto soggettivo di colui che agisce il beneficio: la carica emotiva che lo abita. Figure esemplari di persuasione sono in Michelstaedter non solo esponenti del pensiero filosofico e artistico, ma anche grandi riferimenti religiosi come l’autore dell’Ecclesiaste e Cristo.
Parole chiave: Carlo Michelstaedter; persuasione e rettorica; beneficio; Ecclesiaste; Cristo
Almost all of Carlo Michelstaedter’s writings were published only after his suicide, first by friends V. Arangio-Ruiz and G. Chiavacci, and more recently in many other editions that have made him one of the most read and studied Italian philosophers of the early twentieth century. His reflection is rooted in a Central European context marked by existential crises and philosophical influences ranging from Parmenides and Heraclitus to Ibsen and Nietzsche. He criticizes ‘rhetoric,’ which represents submission to selfish interests and power structures; against rhetoric, he opposes ‘benefit,’ understood as a disinterested openness to the other, and ‘persuasion’ as the subjective aspect of the one who acts for the benefit: the emotional charge that inhabits him. Exemplary figures of persuasion in Michelstaedter are not only representatives of philosophical and artistic thought but also great religious references such as the author of Ecclesiastes and Christ.

Carlo Vallini: restless spirit between dannunzianism and crepuscolarism
openIl progetto di tesi riguarda una ricerca bibliografica da me condotta sull'iter poetico del poeta, drammaturgo e docente Carlo Vallini, personalità vissuta a cavallo fra XIX e XX secolo. Tale figura è stata letterariamente influenzata da altre figure italiane di grande spicco, quali, fra i principali, Giovanni Pascoli e Gabriele D'Annunzio, incuneandosi però anche nella stagione poetica contrassegnata dal movimento del crepuscolarismo (in particolare, stretto legame con Guido Gozzano). Il taglio della mia ricerca verte quindi su un'analisi delle opere principali di Carlo Vallini, maggiormente esprimenti la sua personalità, dando voce ad un autore in bilico fra dannunzianesimo e crepuscolarismo.The thesis project concerns a bibliographic research I conducted on the poetic career of poet, playwright and teacher Carlo Vallini, a personality who lived at the turn of the 19th and 20th centuries. This figure was literarily influenced by other prominent Italian figures, such as, among the main ones, Giovanni Pascoli and Gabriele D'Annunzio, wedging himself, however, also into the poetic season marked by the Crepuscolarismo movement (in particular, close ties with Guido Gozzano). Therefore, the focus of my research is on an analysis of Carlo Vallini's major works, most expressive of his personality, giving voice to an author poised between D'Annunzianism and Crepuscolarism

Valuation of R&D Sequential Exchange Options using Monte Carlo approach
This article describes a methodology for evaluating R&D investment projects using Monte Carlomethods. R&D projects generally involves multiple phases with or without overlapping. R&D investments are made often in a phased manner, with the commencement of subsequent phase being dependent on the successful completion of the preceding phase, it is known as sequential investment. Moreover, each stage creates an opportunity (option) for subsequent investment. Therefore, R&D projects can be considered as ‘Compound Options' in which investments present uncertainty both in the gross project value and in costs. It is possible to use exchange options to value the R&D investment opportunities. In this paper, we propose to value the European and American Real Compound Exchange options through Monte Carlo simulation. We also provide a set of numerical experiments to provide evidence for the accuracy of the proposed methodology.Pseudo Compound American Exchange option; R&D;Monte Carlo Methods.
The Fan and the Idol: Re-tracing Authorship in “The Author of Beltraffio”
This article is an investigation of the theme of authorship in Henry James’s tale “The author of Beltraffio.” Written at a crucial stage of James’s career, this tale stands at the crossroads between James’s high realism, his uneasy flirting with aestheticism, and his more experimental narrative turns. The article argues that in this story authorship is step by step not only mobilized, but also vampirized and dispossessed by the narrator, who exchanges the intimacy with the author and his individuality for commodities to be consumed. Authorship, Martinez contends, is figured in the tale as the result of a social discourse, where the veneration of the narrator for the “author of Beltraffio” borders on the relationship between “fan” and “idol.” Such a gesture is located within the broader cultural concerns James was dealing with at the time: the establishment of literary realism in America; the reconfiguration of the relation between private and public experience; the emergence of a mass readership; and a growing bifurcation between the mutually constituting high-brow and low-brow cultural spheres
