Percorsi relazionali nelle comunità. Minori, buone prassi e rappresentazioni a confronto.
2014
The aim of this thesis was to analyze the context of residential communities for young offenders (Part I) and to analyze the influence of social representations in adolescents and educators (Part II). The first part offers two levels of study on adolescents and on the organizational structure of the community. Adolescents show many problematic levels in the identified variables (Experiences of neglect and abuse during childhood, Attachment Styles, Self-Esteem, Interpersonal Relations, Behavioural problems). No differences between groups of young differentiating according to the reason for placement in community were found. Analysis of community (101 educators from 20 different households) w…
Non-hermitian operator modelling of basic cancer cell dynamics
2018
We propose a dynamical system of tumor cells proliferation based on operatorial methods. The approach we propose is quantum-like: we use ladder and number operators to describe healthy and tumor cells birth and death, and the evolution is ruled by a non-hermitian Hamiltonian which includes, in a non reversible way, the basic biological mechanisms we consider for the system. We show that this approach is rather efficient in describing some processes of the cells. We further add some medical treatment, described by adding a suitable term in the Hamiltonian, which controls and limits the growth of tumor cells, and we propose an optimal approach to stop, and reverse, this growth.

Utilidad de la Paratohormona intraoperatoria en la cirugía del hiperparatiroidismo primario: importancia de su porcentaje de descenso y su valor fina…
2019
El hiperparatiroidismo primario (HPTP) es uno de los trastornos endocrinológicos más frecuentes y supone la primera causa de hipercalcemia en pacientes no hospitalizados. Su diagnóstico aumentó a partir de la década de los 70 del siglo pasado en los países industrializados tras la incorporación del calcio sérico a los análisis automatizados de cribado de rutina. Aunque es difícil establecer la prevalencia real de la enfermedad debido a la existencia de numerosos casos asintomáticos no diagnosticados, en la actualidad se estima una prevalencia del 0,2-1% de la población adulta, siendo la incidencia aproximada de unos 20-30/100.000 habitantes por año. La presentación clínica del HPTP ha evolu…
Single-particle properties of the Hubbard model in a novel three-pole approximation
2017
We study the 2D Hubbard model using the Composite Operator Method within a novel three-pole approximation. Motivated by the long-standing experimental puzzle of the single-particle properties of the underdoped cuprates, we include in the operatorial basis, together with the usual Hubbard operators, a field describing the electronic transitions dressed by the nearest-neighbor spin fluctuations, which play a crucial role in the unconventional behavior of the Fermi surface and of the electronic dispersion. Then, we adopt this approximation to study the single-particle properties in the strong coupling regime and find an unexpected behavior of the van Hove singularity that can be seen as a prec…

Il maschile e il femminile. Una riflessione sulla radice di senso dell'identità di genere
2014
Il tema del maschile e del femminile e il senso della loro reciprocità è percepito come problematico in una cultura come quella attuale, segnata da una propensione all’indifferenziazione sessuale. La questione, per l’elaborazione di un’antropologia pedagogica della sponsalità e della paternità/maternità, è nodale. Il saggio propone una riflessione di stile fenomenologico, volta a ritrovare la radice di senso delle categorie di maschilità e di femminilità, ritrovandole nell’aspetto per cui esso si mostrano costitutive dell’esistenza personale. Tale senso originario resta sempre presente in ogni ricerca e in ogni momento della costruzione della propria singolare identità di genere.
Implementare le politiche sanitarie a livello regionale per l'eliminazione dell'epatite C ai tempi del COVID-19
2022
Viral hepatitis C is an important public health problem and its elimination by 2030, defined by the World Health Organization, is an ambitious goal. The chance of free screening for HCV infection represents an important achievement that requires a successful State-Regions coordination and an effective regional organisation, that guarantees an interdisciplinary course between local and specialized healthcare. A structured communication program to increase the sensitivity of target populations as well as health professionals is the key for success. The implementation of the proactive screening, defined by the Milleproroghe Law, is crucial because it will define the tracks for the whole HCV co…
Bupivacaine 0.5% versus articaine 4% for the removal of lower third molars. A crossover randomized controlled trial.
2012
Objective: To compare the anesthetic action of 0.5% bupivacaine in relation to 4% articaine, both with 1:200,000 epinephrine, in the surgical removal of lower third molars. As a secondary objective hemodynamic changes using both anesthetics were analyzed. Study Design: Triple-blind crossover randomized clinical trial. Eighteen patients underwent bilateral removal of impacted lower third molars using 0.5% bupivacaine or 4% articaine in two different appointments. Preoperative, intraoperative and postoperative variables were recorded. Differences were assessed with McNemar tests and repeated measures ANOVA tests. Results: Both solutions exhibited similar latency times and intraoperative effic…
