Ingenium e natura umana in Giambattista Vico.

2009

Abstract. In the present theories about human nature there are some attempts to naturalize the mind; on the other hand there are tendencies of thought that criticise those ideas. Vico’s work can be considered the foundation of theories which refuse to naturalize humans. Vico had an anti-dualistic view of human nature, centred on ingenium and related to the ideas of action, language, civil world and culture. This essay analyses Vico’s concept of ingenium and proposes a reflection about his epistemology (1), philosophy of mind (2) and philosophy of language (3). (1) Knowledge and truth are connected to human praxis and action. Vico’s theory of knowledge is based on the verum-factum principle.…

A novel boundary element formulation for anisotropic fracture mechanics

2019

Abstract A novel boundary element formulation for two-dimensional fracture mechanics is presented in this work. The formulation is based on the derivation of a supplementary boundary integral equation to be used in combination with the classic displacement boundary integral equation to solve anisotropic fracture mechanics problems via a single-region approach. The formulation is built starting from the observation that the displacement field for an anisotropic domain can be represented as the superposition of a vector field, whose components satisfy a suitably defined anisotropic Laplace equation, and the gradient of the Airy stress function. The supplementary boundary integral equation is …

Quantitative uniqueness estimates for pp-Laplace type equations in the plane

2016

Abstract In this article our main concern is to prove the quantitative unique estimates for the p -Laplace equation, 1 p ∞ , with a locally Lipschitz drift in the plane. To be more precise, let u ∈ W l o c 1 , p ( R 2 ) be a nontrivial weak solution to div ( | ∇ u | p − 2 ∇ u ) + W ⋅ ( | ∇ u | p − 2 ∇ u ) = 0  in  R 2 , where W is a locally Lipschitz real vector satisfying ‖ W ‖ L q ( R 2 ) ≤ M for q ≥ max { p , 2 } . Assume that u satisfies certain a priori assumption at 0. For q > max { p , 2 } or q = p > 2 , if ‖ u ‖ L ∞ ( R 2 ) ≤ C 0 , then u satisfies the following asymptotic estimates at R ≫ 1 inf | z 0 | = R sup | z − z 0 | 1 | u ( z ) | ≥ e − C R 1 − 2 q log R , where C > 0 depends …

Method to Define User Interfaces in the Requirements Analysis Phase

2018

Many requirements for quality in use are elicited in the late development phase. However, if requirements are elicited in the late development phase, the development may return to the previous phase or some requirements cannot be realized due to costs and schedules. To reduce these cases, we propose a method to elicit the requirements in the requirements analysis phase. First, software developers analyze the user characteristics (UCs) of the target users and specify important quality characteristics (QCs) for quality in use and UI design items based on the relationships among UC, QC, and UI design items. Because UI design items are considerations to develop UIs, the specified UI design item…

Generalized Bayesian Pursuit: A Novel Scheme for Multi-Armed Bernoulli Bandit Problems

2011

In the last decades, a myriad of approaches to the multi-armed bandit problem have appeared in several different fields. The current top performing algorithms from the field of Learning Automata reside in the Pursuit family, while UCB-Tuned and the e-greedy class of algorithms can be seen as state-of-the-art regret minimizing algorithms. Recently, however, the Bayesian Learning Automaton (BLA) outperformed all of these, and other schemes, in a wide range of experiments. Although seemingly incompatible, in this paper we integrate the foundational learning principles motivating the design of the BLA, with the principles of the so-called Generalized Pursuit algorithm (GPST), leading to the Gen…

Il paternalismo giuridico tra principio del danno e moralismo giuridico. Alcune riflessioni a partire dal libro di Giorgio Maniaci

2021

Nell’articolo si sostiene che il paternalismo giuridico non costituisce un autonomo principio di criminalizzazione. A tal fine, si analizza il ruolo dell’immoralità dell’atto nel funzionamento dei tre princìpi di criminalizzazione del moralismo giuridico, del principio del danno e del paterna- lismo giuridico: la tesi è che, al di là delle apparenze, tutti e tre questi princìpi suppongano che l’immoralità dell’atto costituisca l’oggetto intenzionale di una criminalizzazione legittima. Que- sta tesi è sostenuta, dapprima, con riferimento specifico al principio del danno, del quale si pro- spettano diversi possibili tipi di moralizzazione, e poi, più diffusamente, con riferimento al pa- terna…

What Can Plans Do for Legal Theory?

2012

In his book, Legality (2011), Scott Shapiro puts forward what he claims to be "a new, and hopefully better" (better, namely, than the ones given so far) answer to "the overarching question of ‘What is law?’ - The central claim of this new account - the "Planning Thesis" - is that "legal activity is a form of social planning" -. "Legal institutions plan for the communities over which they claim authority, both by telling members what they may or may not do, and by identifying those who are entitled to affect what others may or may not do. Following this claim, legal rules are themselves generalized plans, or planlike norms, issued by those who are authorized to plan for others. And adjudicat…

Determination of scattering in intraocular lenses by spectrophotometric measurements.

2014

This study presents a method for measuring scattering in explanted intraocular lenses (IOLs). Currently, determining scattering in IOLs is usually performed by Scheimpflug cameras and the results are expressed in the units used by this apparatus. The method we propose uses a spectrophotometer and this makes it possible to measure the total transmission of the IOL by using an integrating sphere; the direct transmission is determined by the double-beam mode. The difference between these two transmissions gives a value of the scattering in percentage values of light lost. In addition, by obtaining the spectral transmission curve, information about the most scattered wavelengths is also obtaine…

Agreement of predicted intraocular lens power using swept-source optical coherence tomography and partial coherence interferometry

2021

PURPOSE To analyze the agreement of the predicted intraocular lens (IOL) power obtained with ANTERION, IOLMaster 700 and Pentacam AXL biometers. METHODS We calculated the monofocal and trifocal IOL power using the SRK/T, Haigis, Barrett Universal II and Hoffer Q formulas for 106 eyes. IOL power agreement between devices was evaluated using the Bland-Altman method. RESULTS We found significant differences between biometers comparisons (p  0.05), with the same outcomes for medium- and long-eyes. No significant differences were found using the SRK/T, Haigis, or Hoffer Q formulas for short-eyes (p > 0.1). However, Barrett Universal II formula produced significant differences (p < 0.05) and thes…
