Closed Theories, Falsificationism and Non-Cumulative Progress

2020

It is argued that scientific progress occurs not with the cumulative growth of knowledge or when theories get closer to the truth but with discovering new domains and new theories that fit these domains. This horizontal view on the direction of scientific progress (in contrast to vertical, when we aim to get from here to the abstract and ephemeral truth) allows avoiding traditional objections posed by the incommensurability thesis and pessimistic induction, namely, that radical theory changes leave no room for progress. According to this perspective, the discovery of quantum mechanics as a new field of inquiry is a progress in itself, since this discovery had opened up a new distinctive dom…

The Original Position and the Rationality of Primo Levi's Shame

2016

Contrary to what he expected, Primo Levi didn’t experience his life after being released from Auschwitz as cheerful and light-hearted. He – like many other survivors – was haunted by an obscure and solid anguish that he finally identified as springing from a sense of shame or guilt in front of those who were exterminated in the Lager. Levi was unable to either acknowledge his shame as rational or reject it as irrational. This looks, though, like a rather unstable situation calling for some further elucidation. I will thus examine Levi’s shame in light of the dominant conception of practical deliberation and, more specifically, in view of the the role that John Rawls ascribes to the original…

Make It or Break It: The Break-Through Rule as a Break-Through for the European Takeover Directive?

2003

The break-through concept is the most recent idea to break the deadlock with respect to EU takeover legislation. As devised by the High-Level Group of Company Law Experts, chaired by the Dutch Jaap Winter, the break-through concept would do away with two of the most important types of impediments to takeovers within EU member states. The first part of the paper explores the break-through concept in some detail, particularly with respect to its premises, its two guiding principles - exclusive shareholder decisionmaking and proportionality, - and the justifications given by the Group for the proposed interventionist rules. The second part of the paper is dedicated to an analysis of the econom…

IT-Sicherheit in medizinischen Netzen - aktuelle Probleme und Lösungsansätze

2000

Designers and users of medical networks have to face strong requirements for data protection and security. Professional discretion and data protection laws allow the transfer of or access to patient data only in a therapeutic context. These data should also be protected from the network provider. Patients should be safe from any harm by faulty data or buggy procedures. On the other hand the security of the most used software products gets worse and worse. The use of the internet endangers more and more the integrity of the user's computer. The security requirements can be met only through strict care in planning, building, and configuring the infrastructure. Some concrete recommendations an…

Hellinger-Reissner variational principle for stress gradient elastic bodies with embedded coherent interfaces

2017

An Hellinger-Reissner (H-R) variational principle is proposed for stress gradient elasticity material models. Stress gradient elasticity is an emerging branch of non-simple constitutive elastic models where the infinitesimal strain tensor is linearly related to the Cauchy stress tensor and to its Laplacian. The H-R principle here proposed is particularized for a solid composed by several sub-domains connected by coherent interfaces, that is interfaces across the which both displacement and traction vectors are continuous. In view of possible stress-based finite element applications, a reduced form of the H-R principle is also proposed in which the field linear momentum balance equations are…

Elementary presentation of self‐consistent intermediate Hamiltonians and proposal of two totally dressed singles and doubles configuration interactio…

1994

Intermediate Hamiltonians are effective Hamiltonians which are defined on an N‐dimensional model space but which only provide n<N exact eigenvalues and the projections of the corresponding eigenvectors onto the model space. For a single root research, the intermediate Hamiltonian may be obtained from the restriction of the Hamiltonian to the model space by an appropriate, uniquely defined dressing of the diagonal energies or of the first column. Approximate self‐consistent dressings may be proposed. The simplest perturbative form gives the same result as the original 2nd order intermediate Hamiltonian or the ‘‘shifted Bk’’ technique but it is of easier implementation. Self‐consistent inclus…

On approximate system dynamic

1996

In this paper concepts and techniques from system theory are used to obtain state-space (Markovian ) models of dynamic economic processes instead of the usual VARMA models. In this respect the concept of state is reviewed as are Hankel norm approximations,and balanced realizations for stochastic models. We clarify some aspects of the balancing method for state space modelling of observed time series. This method may fail to satisfy the so-called positive real condition for stochastic processes. We us a state variance factorization algorithm which does not require us to solve the algebraic Riccati equation. We relate the Aoki-Havenner method to the Arun - Kung method.

Harmless Rapes? A False Problem for the Harm Principle

2010

ENG.: In this article, I try to show that “harmless rape” (i.e., the case of a rape which is not experienced by its victim) poses no real problem for the harm principle. In order to do this, I first give a critical account of the way in which John Gardner and Stephen Shute have faced this very same topic in a pathbreaking essay they wrote about ten years ago. I contend that their argument undergoes some logical and normative flaws. I will then provide a different account of the harm principle, one that, while reflecting more precisely some of the original Millian intuitions, easily explains why socalled harmless rapes should be criminalized. IT: In questo articolo, cerco di spiegare perché …

The boundary Harnack inequality for infinity harmonic functions in Lipschitz domains satisfying the interior ball condition

2008

Abstract In this note, we give a short proof for the boundary Harnack inequality for infinity harmonic functions in a Lipschitz domain satisfying the interior ball condition. Our argument relies on the use of quasiminima and the notion of comparison with cones.
