Pirate or subscriber? An exploratory study on italian consumers' music habits
Purpose of the paper: This paper analyzes Italian consumers’ music habits in
terms of online piracy behaviors and their interest toward subscription-based music
services (SBMS), i.e. services that for a small monthly fee give users legal access to vast
music libraries across multiple devices. The objective is to try and profile a piracy-prone
consumer and explore if SBMS could be a viable alternative to online music piracy in
Italy, where the general piracy rate is very high.
Methodology: The study is based on an empirical quantitative analysis through the
collection of 505 questionnaires completed by Italian consumers.
Findings: The paper highlights how Italian consumers reflect the ‘attitude-behavior
gap’ in music consumption, as they perceive online music piracy as ethically wrong, yet
they still show low preference for the legal, reasonably priced choice (such as SBMS).
Younger, male, lower education, students have the highest propensity towards online
piracy. In addition, consumers’ awareness, familiarity and interest in subscriptionbased
music services are still very low.
Research limitations: The limitations of the paper are linked mainly to the adapted
scales, to the omission of alternative determinants of attitude towards piracy, to the
composition of the sample and for analyzing only two subscription-based music services
(Napster and Spotify).
Managerial implications: The results call for greater efforts by music industry
actors and public institutions to educate Italian consumers about the consequences of
their online piracy behavior and the possible solutions offered by SBMS.
Originality of the paper: This paper is the first to focus on Italian consumers’
music habits, their attitude and behavior towards online piracy and their interest
toward subscription-based music services as a viable alternative
The two-nucleon electromagnetic charge operator in chiral effective field theory (EFT) up to one loop
The electromagnetic charge operator in a two-nucleon system is derived in
chiral effective field theory (EFT) up to order (or N4LO), where
denotes the low-momentum scale and is the electric charge. The specific
form of the N3LO and N4LO corrections from, respectively, one-pion-exchange and
two-pion-exchange depends on the off-the-energy-shell prescriptions adopted for
the non-static terms in the corresponding potentials. We show that different
prescriptions lead to unitarily equivalent potentials and accompanying charge
operators. Thus, provided a consistent set is adopted, predictions for physical
observables will remain unaffected by the non-uniqueness associated with these
off-the-energy-shell effects.Comment: 16 pages, 10 figure
Electromagnetic Structure and Reactions of Few-Nucleon Systems in EFT
We summarize our recent work dealing with the construction of the
nucleon-nucleon potential and associated electromagnetic currents up to one
loop in chiral effective field theory (EFT). The magnetic dipole
operators derived from these currents are then used in hybrid calculations of
static properties and low-energy radiative capture processes in few-body
nuclei. A preliminary set of results are presented for the magnetic moments of
the deuteron and trinucleons and thermal neutron captures on , , and
He.Comment: Invited talk to the 19th International IUPAP Conference on Few-Body

Nuclear response for the Skyrme effective interaction with zero-range tensor terms. II. Sum rules and instabilities
The formalism of linear response theory for Skyrme forces including tensor
terms presented in article [1] is generalized for the case of a Skyrme energy
density functional in infinite matter. We also present analytical results for
the odd-power sum rules, with particular attention to the inverse energy
weighted sum rule, , as a tool to detect instabilities in Skyrme
functionals.Comment: Submitted to Phys. Rev.
Thermal neutron captures on and He
We report on a study of the and n\,^3He radiative captures at thermal
neutron energies, using wave functions obtained from either chiral or
conventional two- and three-nucleon realistic potentials with the
hyperspherical harmonics method, and electromagnetic currents derived in chiral
effective field theory up to one loop. The predicted and n\,^3He cross
sections are in good agreement with data, but exhibit a significant dependence
on the input Hamiltonian. A comparison is also made between these and new
results for the and n\,^3He cross sections obtained in the conventional
framework for both potentials and currents.Comment: 4 pages, 4 eps figures; references added; corrections to text and

Electromagnetic structure of A=2 and 3 nuclei in chiral effective field theory
The objectives of the present work are twofold. The first is to address and
resolve some of the differences present in independent,
chiral-effective-field-theory (\chiEFT) derivations up to one loop, recently
appeared in the literature, of the nuclear charge and current operators. The
second objective is to provide a complete set of \chiEFT predictions for the
structure functions and tensor polarization of the deuteron, for the charge and
magnetic form factors of 3He and 3H, and for the charge and magnetic radii of
these few-nucleon systems. The calculations use wave functions derived from
high-order chiral two- and three-nucleon potentials and Monte Carlo methods to
evaluate the relevant matrix elements. Predictions based on conventional
potentials in combination with \chiEFT charge and current operators are also
presented. There is excellent agreement between theory and experiment for all
these observables for momentum transfers up to q< 2.0-2.5 (1/fm); for a subset
of them, this agreement extends to momentum transfers as high as q~5-6 (1/fm).
A complete analysis of the results is provided.Comment: 34 pages, Revte
Electromagnetic processes in a EFT framework
Recently, we have derived a two--nucleon potential and consistent nuclear
electromagnetic currents in chiral effective field theory with pions and
nucleons as explicit degrees of freedom. The calculation of the currents has
been carried out to include NLO corrections, consisting of two--pion
exchange and contact contributions. The latter involve unknown low-energy
constants (LECs), some of which have been fixed by fitting the S- and
P-wave phase shifts up to 100 MeV lab energies. The remaining LECs entering the
current operator are determined so as to reproduce the experimental deuteron
and trinucleon magnetic moments, as well as the cross section. This
electromagnetic current operator is utilized to study the and He
radiative captures at thermal neutron energies. Here we discuss our results
stressing on the important role played by the LECs in reproducing the
experimental data.Comment: Invited talk at the 5th International Conference on Quarks and

The Usefulness of Sharing Social Impact Data. Early Findings from an International Benchmarking on SROI Assessments
This paper aims at investigating a perspective for the social impact measurability by collecting and analysing open data at the international level. Our goal is to shed light on the unlocked potential of the knowledge produced by a global community of scholars and practitioners engaged in social impact measurement processes. Global open data on social impact assessment (SIA) have been mapped and collected in a database using the impact chain as a reference point for choosing the variables. In this paper, we focus on the potential use of these data to enable forecasting analysis about the expected social value and to inform decision-making processes aimed at responding to complex social challenges. The early findings suggest the opportunity of a wider action research initiative, by engaging different typologies of stakeholders and organizations aimed at incorporating social impact as a key strategic driver

From sweetwater to seawater: An environmental history of Narragansett Bay, 1636--1849
This dissertation examines environmental change on and around Narragansett Bay from first European settlement in 1636 to the dissolution of the Blackstone Canal Company in 1849. It uses one of the largest estuaries on the East Coast and one situated at the heart of early English settlement in New England as a means to write estuaries into Atlantic history. Examining the ecological and epistemological complexities that arose at the nexus of land and sea, where improvable space and the push of progress met an eternal or profound ocean, this study reframes estuaries as watery borderlands that people used but never fully subdued. In this sense, this work challenges an older historiographical tradition of progress, while it advances environmental historiography by examining not terrestrial or oceanic environments but the soggy spaces in between.
A closer look at the boundary between land and sea, this study shows, provides new insights into the ways Early Modern people envisioned the boundary between humans and nature. By rewriting the history of an estuary from the ground up, so to speak, this work explores the ways people shaped a watery world and how it shaped them in return. It argues that at the confluence of sweetwater and seawater, in the mixing, muddy margins of an estuary, there developed a whole host of political, legal, and cultural ambiguities that shaped patterns of settlement, trade, resource use, and ultimately the Bay itself But much more than the passive recipient of human action, the Bay became a cultural manifestation of the people who lived along its shores, and in consequence it was shaped and reshaped to meet the changing demands of human desire
