Jürgen Habermas. Il paradigma dell'agire comunicativo
2000
Il saggio descrive il pensiero dello studioso francofortese, individuandone criticamente i principali snodi concettuali sia nell'ambito più squisitamente filosofico sia le conseguenze e gli sviluppi sul piano socio-politico.
Consultare per valutare
2020
Questo capitolo esamina la consultazione all'interno del processo di policy, presentandone le caratteristiche generali. Vengono trattate nello specifico alcune tecniche di consultazione, evidenziando per ciascuna di esse i punti di forza e di debolezza definiti anche sulla base degli obiettivi conoscitivi che ci si propone di raggiungere e indicando un percorso alquanto pragmatico e operativo. This chapter examines the consultation within the policy process, presenting its general characteristics. Specific consultation techniques are dealt with, highlighting for each of them the strengths and weaknesses defined also on the basis of the cognitive objectives that we intend to achieve and indi…
La formación de la imagen de los Siete Príncipes. Descripción diacrónica, fuentes y hermenéutica
2009
El presente estudio trata sobre la aparición de la imagen de los Siete Príncipes, analizando la tradición de ésta, observando cómo se desarrolló compositiva e iconográficamente el tipo iconográfico de los Siete Príncipes, y abordando la interpretación de la imagen y culto a estos arcángeles. Para ello retoma las fuentes principales de la angelología y analiza las principales obras de los tratadistas angélicos de los siglos XVII y XVIII. The present study deals with the first appearance of the image of the Seven Princes. Studying the tradition behind this image, I analyze how the iconographic type of the Seven Princes, evolved both from the point of view of composition as well as iconography…
It takes two to tango
2003
Abstract In most taxa, females are more likely than males to care for offspring. Why? Ever since Trivers' landmark work, the answer has been traced back to sexual differences in pre-mating reproductive investment (unequal gamete size or anisogamy). However, recent work shows that parental investment theory has inadvertently ignored a profoundly simple fact of life: every offspring has a mother and father. Taking this into account completely changes how we should think about sex differences in parental care.
Multi-spectral mapping of in vivo skin hemoglobin and melanin
2010
The multi-spectral imaging technique has been used for distant mapping of in-vivo skin chromophores by analyzing spectral data at each reflected image pixel and constructing 2-D maps of the relative concentrations of oxy-/deoxyhemoglobin and melanin. Instead of using a broad visible-NIR spectral range, this study focuses on narrowed spectral band 500-700 nm, so speeding-up the signal processing procedure. Regression analysis confirmed that superposition of three Gaussians is optimal analytic approximation for the oxy-hemoglobin absorption tabular spectrum in this spectral band, while superposition of two Gaussians fits well for deoxy-hemoglobin absorption and exponential function - for mela…
Multiple-Output Walsh Function Generation for Minimum Orthogonality Error
1978
A hazard-free multiple-output Walsh function generator is presented which requires a minimum amount of hardware and is as fast as the integrated logic family employed for the implementation. However, the main characteristic of the instrument is the optimum performance from the viewpoint of the orthogonality of the function generated, as it is shown by the experimental verifications reported.
Selective aqueous oxidation of aromatic alcohols under solar light in the presence of TiO2 modified with different metal species
2022
AbstractA set of metals modified TiO2 photocatalysts were prepared starting from titanium tetraisopropoxyde and different metal precursors to study the influence of the addition of the various foreign agents on the physico-chemical and photocatalytic properties of the catalysts. The powders were characterized by X-ray diffraction, Raman spectroscopy, specific surface area measurements, scanning electron microscopy, energy dispersive X-ray spectroscopy, UV–Vis diffuse reflectance spectroscopy, photoluminescence, temperature programmed desorption after CO2 adsorption. The photocatalytic activity was evaluated using as probe reactions the partial oxidation of three aromatic alcohols: benzyl al…

Conflitto e bilanciamento in ambito canonico, tra norma penale in bianco e principio di legalità
2021
Il sistema penale canonico appare segnato da una vistosa contraddizione: da un lato accoglie il principio di legalità, con i suoi corollari del divieto dell’argumentum a simili, dei criteri di stretta interpretazione e di retroattività della lex mitior; dall’altro, esso contempla una disposizione, il can.1399, che con il suo carattere improprio di norma in bianco, apre alle fattispecie atipiche consentendo di perseguire l’infrazione di una legge anche «oltre i casi espressamente stabiliti» dal codice o da altre leggi penali. Le ragioni di tale antinomia possono, ad un esame più approfondito, risultare indebitamente condizionate da un parametro troppo stretto di declinazione della legalità p…
An Itô Formula for rough partial differential equations and some applications
2020
AbstractWe investigate existence, uniqueness and regularity for solutions of rough parabolic equations of the form $\partial _{t}u-A_{t}u-f=(\dot X_{t}(x) \cdot \nabla + \dot Y_{t}(x))u$ ∂ t u − A t u − f = ( X ̇ t ( x ) ⋅ ∇ + Y ̇ t ( x ) ) u on $[0,T]\times \mathbb {R}^{d}.$ [ 0 , T ] × ℝ d . To do so, we introduce a concept of “differential rough driver”, which comes with a counterpart of the usual controlled paths spaces in rough paths theory, built on the Sobolev spaces Wk,p. We also define a natural notion of geometricity in this context, and show how it relates to a product formula for controlled paths. In the case of transport noise (i.e. when Y = 0), we use this framework to prove a…
