On the growth of structures in Galileon cosmologies
Full text linkIn this thesis I have presented a cosmological research, focused on the study
of some aspects of the growth of structures in Galileon cosmologies. Galileon
is an effective field theory which is constructed in order to explain the ac-
celerated expansion of the universe at late-times.
First, we have focused on the study of the spherical collapse model, which
studies the dynamics of a spherical top-hat Dark Matter density perturba-
tion in the highly non-linear regime. This investigation is useful in order to
understand the properties of the objects present in our universe, i.e. galaxies
and cluster of galaxies.
The second part of my thesis is devoted to the study of the non-Gaussianities,
in particular we have calculated the Dark Matter bispectrum generated at
late-times by gravitational instability in Galileon cosmologies. The interest
in studying the dark matter bispectrum in the Galileon model stems from the
possibility to measure the signature of modifications from standard gravity

No full textSpherical collapse in covariant Galileon theory
No full textIn this paper we study the evolution of a spherical matter overdensity in the context of the recently introduced Galileon field theory. Our analysis considers the complete covariant Lagrangian in four dimensions. This theory is composed by a potential and a standard kinetic term, a cubic kinetic term and two additional terms that include the coupling between the Galileon and the metric, to preserve the original properties of Galileons also in curved space-times. Here we extend previous studies, which considered both the quintessence and the cubic terms, by focussing on the role of the last two terms. The background evolution we consider is driven by a tracker solution. Studying scalar perturbations in the non-linear regime, we find constraints on the parameter of the model. We will show how the new terms contribute to the collapse phase and how they modify physical parameters, such as the linearized density contrast and the virial overdensity. The results show that the Galileon modifies substantially the dynamics of the collapse, thus making it possible to observationally constrain the parameters of this theory
Embedding Values into Digital Artifacts
Full text linkThe shift toward digital offerings poses challenges for companies that are adapting their development process
from creating physical products to new digital artifacts. The ways in which companies design physical products and their
interaction with customers is not effective in the digital domain. This article outlines how Sorgenia, a fast-growing utility
company in Italy, conceptualized and designed the mobile app its consumers use to access its services. The classical dimensions
of the user experience (aesthetic, emotional, and symbolic) need to be layered and coordinated throughout the customer’s
interaction with the app to make the underlying values emerge progressively. In doing so, customers can be guided
to comprehend a digital artifact fully, overcoming the interpretive barriers caused by the lack of physicality
Radical Innovation of Retail Services: Enriching the Customer Experience Proposing New Meanings
No full textTechnology-Aided Customer Experience Innovation : Implementation Modes in Retail
Full text linkRetailers are increasingly leveraging emerging digital technologies to enhance and deliver memorable and timely customer experiences. However, more research is needed to understand how these technologies are being implemented. Therefore, we conducted an fsQCA analysis of 32 retail cases of early adopters of beacon technology. Our findings reveal three main modes of implementation of emerging digital technologies in the retail customer experience: automation, augmentation, and customization. These modes can be interpreted as enablers that enhance the value of utilitarian and/or hedonic experiences, rather than as drivers of innovation per se. Our study adds a new perspective to the debate about the role of digital technologies in driving innovation. Moreover, the three modes identified provide managers with practical guidelines for the implementation of emerging digital technologies in retail environments.

Filtering and enabling meaning perception: a business model perspective
No full textThis study aims at expanding the innovation of meaning framework by investigating how a new meaning strategy can be adapted to different contexts, building on a case study based on the comparison between two service companies. The analysis takes into account both the companies' strategy, assessed through interviews with the founder and secondary sources analysis, and the customers' side, combining an ethnographic research with a topic modelling of customer reviews. Findings suggest that companies can convey their overarching meaning strategy in different ways by shaping the way value is delivered to the final users. This study enriches both the innovation of meaning discourse and the literature on the business model by highlighting how to convey an adapted meaning to different contexts. This article provides actionable knowledge to practitioners by suggesting how to contextually adapt a company's meaning strategy to different environments through the intervention on specific business model elements
