Controlli societari e posizioni di garanzia. Un'indagine alla luce del d.lgs. 231/2001
Full text linkThe research aims to examine the impact of Legislative Decree 231/2001, which has established a regulation of criminal compliance and liability of corporations, on the responsibility for the omission to prevent crimes of the members of corporate bodies entrusted to adopt and put into effects compliance programs, and to monitor the operation of such programs.
The first part of the thesis contains a doctrinal analysis, which intends to define the requirements of omission to act, with particular attention to the “duty to act” as a criterion of equivalence between the commission of a crime and the failure to prevent the commission of a crime.
In the light of the results achieved, the second part of the thesis attempt to reconstruct the case law about the powers of the corporate controllers to prevent the commission of crimes within the management of corporations.
Eventually the thesis monitors how Legislative Decree 231/2001 has modified the dynamics of corporate controls with the introduction of a system of criminal compliance, that is a set of duties of corporations aimed at the prevention of crimes committed in their interest or benefit by their members.
The research also features profiles of comparison with the US system of corporate criminal liability, which has inspired the italian system, and with the German system, since the German legislation, doctrine and jurisprudence have a leading role in the conceptualization of the responsibility for omission to act
A case of subdominant/suppressed “high energy” contribution to the baryon asymmetry of the Universe in flavoured leptogenesis
No full textAbstractThe CP-violation necessary for the generation of the baryon asymmetry of the Universe YB in the “flavoured” leptogenesis scenario can arise from the “low energy” PMNS neutrino mixing matrix U and/or from the “high energy” part of neutrino Yukawa couplings, which can mediate CP-violating phenomena only at some high energy scale. The possible interplay between these two types of CP-violation is analysed. The type I see-saw model with three heavy right-handed Majorana neutrinos having hierarchical spectrum is considered. We show that in the case of inverted hierarchical light neutrino mass spectrum, there exist regions in the corresponding leptogenesis parameter space where the relevant “high energy” phases have large CP-violating values, but the purely “high energy” contribution in YB plays a subdominant role in the production of baryon asymmetry compatible with the observations. In some of these regions the purely “high energy” contribution in YB is so strongly suppressed that one can have successful leptogenesis only if the requisite CP-violation is provided by the Majorana phase(s) in the neutrino mixing matrix

Low energy signatures of the TeV scale seesaw mechanism
No full textWe study a type I see-saw scenario
where the right-handed (RH) neutrinos, responsible
for the light neutrino mass generation, lie
at the electroweak scale. Under certain conditions, the strength of
the charged (CC) and neutral current (NC) weak
interactions of the Standard Model particles with the
heavy RH neutrinos can be large enough
to allow the production of the latter at the LHC,
opening also the possibility of
observing other low energy signatures of the new physics in the electroweak
precision observables as well as in searches for rare leptonic decays
or neutrinoless double beta decay.
In this scenario the flavour structure of the
indicated CC and NC couplings of the heavy RH neutrinos
is essentially determined by the low energy
neutrino parameters,
leading to fairly strong correlations among the
new phenomena.
In particular, we show that the present
bound on the decay rate
makes very difficult the observation of the
heavy RH neutrinos at the LHC or the observation of deviations
from the Standard Model predictions in the electroweak precision data.
We also show that all present experimental
constraints on this scenario
still allow i) for an enhancement of the rate of
neutrinoless double beta decay,
which thus can be in the
range of sensitivity
of the GERDA experiment even when
the light Majorana neutrinos possess
a normal hierarchical mass spectrum,
and ii) for the predicted
decay rate
to be within the sensitivity range of the
MEG experiment
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
L'Agudeza y arte de ingenio e il Cannocchiale aristotelico: il ruolo del De arte rhetorica di Cipriano Soarez
No full textThe interplay between "low" and "high" energy CP-violation in leptogenesis
No full textWe analyse, within the "flavoured" leptogenesis scenario of baryon asymmetry generation, the interplay of "low energy" CP-violation, originating from the PMNS neutrino mixing matrix U, and "high energy" CP-violation, which can be present in the matrix of neutrino Yukawa couplings, lambda, and can manifest itself only in "high" energy scale processes. The type I see-saw model with three heavy right-handed Majorana neutrinos having a hierarchical spectrum is considered. The "orthogonal" parameterisation of the matrix of neutrino Yukawa couplings, which involves a complex orthogonal matrix R, is employed. In this approach the matrix R is the source of "high energy" CP-violation. Results for normal hierarchical (NH) and inverted hierarchical (IH) light neutrino mass spectrum are derived in the case of decoupling of the heaviest right-handed Majorana neutrino. It is shown that taking into account the contribution to Y (B) due to the CP-violating phases in the neutrino mixing matrix U can change drastically the predictions for Y (B) , obtained assuming that only "high energy" CP-violation from the R-matrix is operative in leptogenesis. In the case of the IH spectrum, in particular, there exist significant regions in the corresponding parameter space where the purely "high energy" contribution in Y (B) plays a subdominant role in the production of baryon asymmetry compatible with the observations
