Il traffico di beni culturali: un caso studio delle distorsioni e dei limiti nel contrasto ai traffici illeciti
2021
La normativa penale italiana di contrasto al traffico di beni culturali presenta ad oggi diversi profili di criticità, a fronte del prosperare del fenomeno delittuoso e dell’indiscutibile rilievo costituzionale del bene protetto. La revisione della disciplina, per quanto necessaria, non può però assumere i contenuti della proposta di riforma attualmente pendente in Senato. Infatti, questa, come accade nel caso degli altri commerci illegali, risente eccessivamente dell’influenza della normativa in tema di organizzazioni criminali, presentandosi come una mera appendice della stessa. L’A. in questo contributo, dopo aver ricostruito la disciplina penale di riferimento, evidenzia piuttosto l’esi…
Institutional Arrangements Matter for Both Efficiency and Distribution: Contributions and Challenges of the New Institutional Economics
2011
Are scholars in the New Institutional Economics tradition systematically disregarding distributive aspects when approaching policy issues as was the case during the 1970s and 1980s? Do economic and political agents usually care about distribution too? To provide an answer to these questions is the basic purpose of this chapter. The analysis carried out demonstrates that not all NIE oriented scholars disregard distributive issues. Some contributions are examined as examples, mainly in the so-called political economy branch of NIE. By means of a well-known graphical tool, the chapter also emphasizes that all of us clearly care about distribution, not just about efficiency, when participating …
Drivers influencing the governance of inter-firm relationships in the biopharmaceutical industry: an empirical survey in the Italian context
2013
This paper focuses on factors influencing the choice of the governance form in inter-firm relationships (IFRs) between pharmaceutical and biotechnology companies. By reviewing the relevant literature on transaction cost economics, property right theory, real option and resources-based view, we located some drivers that might influence such relationships and we formulated a set of hypotheses linking them to governance forms. Such a theoretical framework has been empirically tested through a survey conducted among the Italian companies associated to Farmindustria. Empirical results provide some interesting insights on how shaping bio-pharmaceutical deals; we found that the developmental stage…
How the purpose of the inter-firm relationships influences the choice of the governance form: evidence from the machine tool and the pharmaceutical i…
2013
In today's competitive landscape, the choice of the appropriate mode to govern an inter-firm relationship is a critical factor for companies. In the literature several theoretical strands have examined the impact of the purpose of inter-firm relationships on the forms of governance. Building on a robust literature review on the topic, this study focuses on a specific issue influencing the choice of the form of governance in inter-firm relationships, i.e. the purpose of inter-firm relationships with relation to partner's resources. We gather in a unique framework three typologies of partner's resources, i.e. production, R&D and marketing, and through two empirical analyses in two different I…
On C1 robust singular transitive sets for three-dimensional flows
1998
Abstract The main goal of this paper is to study robust invariant transitive sets containing singularities for C 1 flows on three-dimensional compact boundaryless manifolds: they are partially hyperbolic with volume expanding central direction. Moreover, they are either attractors or repellers. Robust here means that this property cannot be destroyed by small C 1 -perturbations of the flow.
Hydrogels in maxillofacial prosthesis
2017
Background: There is a growing need for prosthetic replacements in humans due to various reasons. Oro-facial deformities contribute more for these treatment modalities due to impairment in both function and esthetics. Biomaterials play an important role in replacing any form of defects. Selection of a good biomaterial is of prime importance as these materials determine the success of the treatment outcome. Acrylic resins and silicones are the most popular materials for replacing the lost tissues as far as the maxillofacial prosthesis is concerned. But these materials only help in covering the defect and give a very little therapeutic effect. Acrylic resins are very rigid materials and are l…
Enantioseparations with polysaccharide-based chiral stationary phases in HPLC. Application to the enantioselective evaluation of the biodegradability…
2023
The chiral nature of living systems has obvious implications for the biologically active compounds that interact with them. At the molecular level, chirality represents an intrinsic property of the essential building blocks of life, such as amino acids and sugars, and therefore, of peptides, proteins, enzymes, carbohydrates, nucleosides and a number of alkaloids and hormones. As a consequence, processes mediated by biological systems are stereochemistry-sensitive, and a pair of enantiomers can have different effects on living organisms. The scientific community has been studying the implications of chirality for life for more than a century. Today, it is still a topic of active research and…
Fredholm operator families ?II
1984
First, we give a characterization of semi-Fredholm operators (i.e. those which are left or right invertible modulo compact operators) on Hausdorff tvs which generalizes the usual one in the context of Banach spaces. Then we consider a class of semi-Fredholm operator families on tvs which include both the "classical" semi-Fredholm operator valued functions on Banach spaces (continuous in the norm sense), and families of the form T + Kn, where Kn is a collectively compact sequence which converges strongly to O. For these families we prove a general stability theorem.
Property (w) for perturbations of polaroid operators
2008
Abstract A bounded linear operator T ∈ L ( X ) acting on a Banach space satisfies property ( w ) , a variant of Weyl’s theorem, if the complement in the approximate point spectrum σ a ( T ) of the Weyl essential approximate-point spectrum σ wa ( T ) is the set of all isolated points of the spectrum which are eigenvalues of finite multiplicity. In this note, we study the stability of property ( w ) for a polaroid operator T acting on a Banach space, under perturbations by finite rank operators, by nilpotent operators and, more generally, by algebraic operators commuting with T.
Operators which have a closed quasi-nilpotent part
2002
We find several conditions for the quasi-nilpotent part of a bounded operator acting on a Banach space to be closed. Most of these conditions are established for semi-Fredholm operators or, more generally, for operators which admit a generalized Kato decomposition. For these operators the property of having a closed quasi-nilpotent part is related to the so-called single valued extension property.
