La forma escatologica del sacramento. Evento della Parola
No full textIl contributo elabora il nesso che intercorre tra la dimensione escatologica e la pratica sacramentale, per illustrare un possibile modello che intenda come non separabili né alternative la temporalità e l'eternità.
La considerazione del sacramento quale evento escatologico è ottenuta tramite la considerazione della Parola, nella sua manifestazione nello scritto biblico, quale fenomeno dell'incontro tra la singolarità umana e la trascendenza divina
L’epoca secolare: fedeltà al vangelo e dedizione alla storia. Hans Urs von Balthasar e Christoph Theobald
No full textLe prospettive teologiche di Christoph Theobald e Hans Urs von Balthasar divergono a riguardo di questioni fondamentali: cristologia, antropologia, estetica. Al contempo, i due modelli teorici che propongono sono di particolare interesse per valutare il ruolo del cristianesimo nell'epoca post secolare.
Dopo una breve ricostruzione del dialogo che Theobald intesse con Balthasar viene messo in luce come entrambe le prospettive sappiano valorizzare il ruolo fondamentale della storia e della dimensione antropologica quali conseguenze necessarie della forma della Rivelazione cristiana
Il soggetto e la sua nascita: suggestioni dalle opere di Jean-Louis Chrétien
No full textIl contributo mette in luce i luoghi della produzione di Jean-Louis Chrétien nei quali è indagato il tema della nascita. In particolare, viene considerato il nesso tra la prima nascita e la seconda nascita quale struttura che consente l'attuarsi della identità personale a partire dal legame con l'alterità costruito nella storia
Il segreto della libertà
No full textLungo tutto il suo sviluppo la ricerca del teologo milanese Sergio Ubbiali si è caratterizzata per l’interesse di tipo fondamentale, declinato nell’ambito dell’antropologia, della sacramentaria, dell’escatologia, con un chiaro rimando alla postura fenomenologica.
Il volume Il segreto della libertà omaggia tale percorso, con saggi filosofici e teologici, offerti da colleghi, amici e discepoli, provenienti dall’ambito di ricerca italiano, francese e tedesco
Clinical evaluation of probucol in hypercholesteremia: individual lipoprotein responses and inhibitory effect on carotid atherosclerosis progression
No full textProbucol treatment has been evaluated in 140 patients with hypercholesterolemia attending a single Lipid Clinic, in an attempt to identify the relations between lipid/lipoprotein responses and patient characteristics. Probucol was administered as a single drug at the standard dose (0.5 g tablets b.i.d.) for at least 6 months. One-hundred (71%) patients displayed a reduction of low-density lipoprotein cholesterol (LDL-C), which was significantly correlated with the baseline LDL-C level (r = 0.64; p < 0.0001). Most of the patients (90%) also responded with a reduction of high-density lipoprotein cholesterol (HDL-C); the HDL-C reduction was also directly related to baseline HDL cholesterolemia (r = 0.67, p < 0.0001). A highly significant correlation was found between the individual LDL-C and HDL-C responses. Eleven patients who continued with probucol treatment had a B-mode ultrasonographic investigation performed at baseline and after 24 months. No changes in carotid mean and maximal intimal-medial thickness were recorded, in contrast to an increase (i.e., indicative of atherosclerosis progression) in matched patients with hypercholesterolemia receiving other lipid-lowering regimens. Our report underlines that probucol can still provide a valuable option for the treatment for hypercholesterolemia, being particularly effective in patients with a combined increase of LDL-C and HDL-C levels
Test procedures for the evaluation of defect tolerance of electrically-stressed polymers
No full textThe influence of conductive defects, able to amplify electric field magnitude, on insulation breakdown is investigated in this paper by short-term tests. Appropriate test cells were used, made according to a Rogowski profile, where a set of semiconductive needle-shaped indents starting from the outer surface is realized. Samples of XLPE specimens were tested, differing for the types of additives used as voltage stabilizer and electrical tree retardant. The results of electric strength measurements are dealt with in the paper, with the purpose to show that the proposed test cell provides Weibull-distributed breakdown data, characterized by acceptable confidence intervals and repeatability. This enables an effective comparison between materials, even in the case that the presence of additives does not change remarkably material performances. Moreover, the multiplicity of indents helps in averaging the considerable influence of the curvature radius of needles, which may play a fundamental role in the usual test cells realized by needle-plane electrode configuration
Some remarks regarding the test cells used for electric strength measurements
No full textThis paper deals with the influence of the test cell on the results of electric strength measurements performed on polymeric materials. Two different types of electrodes are considered, i.e. rods and Pseudo-Rogosky configurations, surrounded by different media, that is, oil, SF6, and epoxy resin. An Ethylene-Propylene-Rubber (EPR)-based insulation was tested, in the form of flat specimens having different thickness. The results show that the scale and shape parameters of the two-parameter Weibull function employed to fit the breakdown data significantly changes when different specimen thickness, surrounding media and types of electrodes are used
Clinical response to probucol in hypercholesterolemia: peculiar sensitivity of different subpopulations
No full textThe effectiveness of probucol therapy in group of 140 hypercholesterolemic patients who had been treated with probucol for at least six months, up to two years, was investigated in this study. The responses, in terms of individual percentage reduction of plasma LDL-C levels, have been evaluated trying to assess the sensitivity of specific subgroups of patients and their response to treatment. Clinical data and plasma lipid/lipoprotein levels were determined at baseline, at the sixth month and then at the end of 2 years. To identify and characterize subpopulation showing different sensitivity to the probucol treatment, the effectiveness of probucol therapy was related to the sex hormonal status and major lipid or non lipid parameters. Response to probucol was evaluated after stratification of patients by sex, tertiles of HDL-C levels (at baseline) and pre-/post-menopausal status in women. After six months plasma LDL-C levels was reduced of 7.0%. Stratifying patients into tertiles of HDL-C levels, the LDL-C response after six months of treatment was about 8.30% in the higher tertile group, vs a 6.5% of the lower. However in all patients who have been treated and followed for 2 years, the maximum LDL-C reduction was achieved at the end of the second year (11.6%
The right to a good State
No full textEste artículo recupera la refexión de O’ Donnell sobre las formas modernas del autoritarismo militar, los procesos de democratización, los desafíos que presentan los procesos de institucionalización democrática en América latina. El autor, en Democracia, agencia y estado se embarca en un proyecto de teoría política orientado a elaborar una teoría democrática “con intención comparativa” que permita abrir líneas de discusión teórica e investigación empírica sobre la experiencia de la democratización en países que no pertenecen a lo que él denomina `el cuadrante Noroccidental del mundo´. La fuente de inspiración de dicha teoría, aclara el autor, es la preocupación por las falencias que presentan varias de las democracias latinoamericanas contemporáneas.This article shows the reflection of Guillermo O ‘Donnell on modern forms of military authoritarianism, democratization and the challenges of the process of institutionalization of democracy in Latin America. The author, in Democracia, agencia y estado develops democratic theory “with comparative intent” to allow open lines of theoretical discussion and empirical research on the experience of democratization in countries that do not belong to what he calls `the Northwest quadrant of the world´. The inspiration for this theory, the author explains, is the concern for the failings that have several contemporary Latin American democracies.Fil: Peruzzotti, Carlos Enrique.

Immagini malgrado tutto. L'eredità di Aby Warburg agli occhi della teologia
No full textIl contributo offre una lettura teologica dell'opera di Aby Warburg e delle sue intuizioni sul mondo dell'immagine.
