Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily
2018
L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…

The purpose of the paper is to investigate ultradistributions of both Beurling and Roumieu (briefly, B and R) types with the help of a sequential approach, considering certain equivalence classes of fundamental sequences of smooth functions defined by ultradifferential operators. More precisely, the authors define as s-ultradistributions the equivalence classes U(t) and U{t} of B and R types respectively on test functions belonging respectively to D′(t)(Ω) and D′{t}(Ω) on the open set Ω⊂Rn, and T(t), T{t}, T~(t) and T~{t} of (tempered) t- and t~-distributions, and study their properties. Finally, the authors prove the existence of topological isomorphism between the classes T(t), T{t}, T~(t…
On a regularized approach for the method of fundamental solution
2018
The method of fundamental solution is a boundary meshless method recently adopted in the framework of non-invasive neu- roimaging techniques. The method approximates the solution of a BVP by a linear combination of fundamental solutions of the governing PDE. A crucial feature of the method is the placement of the fictitious boundary to avoid the singularities of fundamental solutions. In this paper we report on our experiences with a regularized MFS method in the neuroimaging context.
A meshfree approach for brain activity source modeling
2015
Weak electrical currents in the brain flow as a consequence of acquisition, processing and transmission of information by neurons, giving raise to electric and magnetic fields, which are representable by means of quasi-stationary approximation of the Maxwell’s equations. Measurements of electric scalar potential differences at the scalp and magnetic fields near the head constitute the input data for, respectively, electroencephalography (EEG) and magnetoencepharography (MEG), which allow for reconstructing the cerebral electrical currents and thus investigating the neuronal activity in the human brain in a non-invasive way. This is a typical erectromagnetic inverse problem, since measuremen…
Scritti in onore di Pellegrino Capaldo
2014
La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…
The monodromy groups of Dolgachev's CY moduli spaces are Zariski dense
2014
Let $\mathcal{M}_{n,2n+2}$ be the coarse moduli space of CY manifolds arising from a crepant resolution of double covers of $\mathbb{P}^n$ branched along $2n+2$ hyperplanes in general position. We show that the monodromy group of a good family for $\mathcal{M}_{n,2n+2}$ is Zariski dense in the corresponding symplectic or orthogonal group if $n\geq 3$. In particular, the period map does not give a uniformization of any partial compactification of the coarse moduli space as a Shimura variety whenever $n\geq 3$. This disproves a conjecture of Dolgachev. As a consequence, the fundamental group of the coarse moduli space of $m$ ordered points in $\mathbb{P}^n$ is shown to be large once it is not…
Pozytywne definicje rodziny chrześcijańskiej w magisterium papieskim po Soborze Watykańskim II jako wyzwanie dla inicjatyw duszpasterskich w Roku Rod…
2021
W nauczaniu Kościoła rodzina oparta na związku mężczyzny i kobiety jawi się jako duszpasterski priorytet i podstawowa rzeczywistość, której należy poświęcać szczególną uwagę. W związku z Synodem Biskupów o Rodzinie ów temat często pojawiał się w medialnych i naukowych dyskusjach. Należy jednak zauważyć, że prezentowany w nich obraz rodziny nie zawsze odnosił się do jej pozytywnego wymiaru. W debatach niejednokrotnie pojawiały się kwestie związane z kryzysem rodziny, podejmowano dyskusje dotyczące miejsca rozwodników w Kościele i ich ewentualnego dopuszczenia do komunii św., zajmowano się szeregiem niepokojących faktorów zmierzających do osłabienia czy nawet dezintegracji tej podstawowej kom…
The Challenges and Opportunities of Human Technology
2005
Technology is for human use. It is designed to satisfy some human needs and to aid people in reaching their goals. Technology, therefore, is a part of human activities and, for this reason alone, it should always be considered within the context of human life, the human experience. This basic credo forms the foundation for the concept of human technology. Instead of seeing technology as a construction following the laws of nature, the challenge of human technology is to explore and understand how humanist and social research can contribute to the conceptualization and implementation of technology.
Intentions to drop-out of youth soccer: A test of the basic needs theory among European youth from five countries
2013
Research arising from self-determination theory (SDT; Deci, E. L., & Ryan, R. M. (2000). The “what” and “why” of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11(4), 227–268) indicates that the quality of the social interactions between athletes and coaches, and athletes' ensuing psychological responses, are critical determinants of intentions to drop out of youth sport. Little is known regarding whether these processes hold across countries. Grounded in SDT, this study tested the invariance of a model predicting youth sport dropout across five European countries. Seven thousand seven hundred and sixty-nine grassroots players (6641 males, 1020 fem…
