“Afferrare” l’economia. Percezioni e proiezioni dell’impresa nel diritto dell’età industriale

2013

Percorsi storico-giuridici dell'impresa. Dall’«entreprise» all’«Unternehmen».

2012

Dal primo Ottocento le dinamiche organizzative della produzione industriale proiettano l’impresa al cuore del sistema economico. La sua naturale vocazione a comporre in un’organizzazione unitaria gli elementi personali e patrimoniali della produzione ne fa il paradigma ideale di un modello economico-sociale fondato sulla complessità degli apporti, sulla pluralità dei contatti, sull’equilibrio degli interessi collettivi. Alla centralità assunta nella sfera economica, tuttavia, non corrisponde un’eguale considerazione dell’impresa sul piano giuridico. Il Code de commerce del 1807 disegna un diritto a misura d’individuo, segue le logiche semplici ed unilineari del nuovo ordine, votandosi allo …

A Bioinformatics Analysis of Lamin A Regulatory Network: a Perspective on Epigenetic Involvement in Hutchinson-Gilford Progeria Syndrome

2011

Hutchinson-Gilford progeria syndrome (HGPS) is a rare human genetic disease that leads to premature ageing and ageing-associated phenotype. HGPS is caused by mutation in the lamin A (LMNA) gene that leads, in affected young individuals, to the generation of progerin, a splicing mutant of lamin A. A bioinformatics analysis of the LMNA gene network of interactions is presented. Lamin A seems to be involved in epigenetic regulation of transcription, chromatin remodelling, DNA repair, with key roles in stemness regulation, normal ageing and telomere functions. The study suggests particular relevance of chromatin remodellers and histones covalent modifiers in the LMNA network. Specifically, HTAT…

Fundoplicatio sec. Nissen videolaparoscopica e metaplasia intestinale in esofago: osservazioni preliminari

2005

The aim of this preliminary study conducted in a few cases was the retrospective evaluation of the effects of laparoscopic Nissen fundoplication on oesophageal intestinal metaplasia. Seventy-seven patients with hiatal hernia underwent digital videofluorography, endoscopy with biopsies, motility studies and 24-h oesophageal pH-monitoring. On the basis of the results of the diagnostic procedures and considering the patients' ages and response to proton-pump inhibitor treatment, 8 patients underwent laparoscopic Nissen fundoplication; in 5 cases intestinal metaplasia was present at histopathological examination. Two of these had Barrett's oesophagus at endoscopy and intestinal metaplasia was a…

Rapid oxidation of mercury (Hg) at volcanic vents: Insights from high temperature thermodynamic models of Mt Etna's emissions

2011

A major uncertainty regarding the environmental impacts of volcanic Hg is the extent to which Hg is deposited locally or transported globally. An important control on dispersion and deposition is the oxidation state of Hg compounds: Hg(0) is an inert, insoluble gas, while Hg(II) occurs as reactive gases or in particles, which deposit rapidly and proximally, near the volcanic vent. Using a new high temperature thermodynamic model, we show that although Hg in Etna's magmatic gases is almost entirely Hg(0) (i.e., gaseous elemental mercury), significant quantities of Hg(II) are likely formed at Etna's vents as gaseous HgCl2, when magmatic gases are cooled and oxidised by atmospheric gases. Thes…

A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS

2016

Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…

Shape staggering of midshell mercury isotopes from in-source laser spectroscopy compared with density-functional-theory and Monte Carlo shell-model c…

2019

Neutron-deficient Hg177-185 isotopes were studied using in-source laser resonance-ionization spectroscopy at the CERN-ISOLDE radioactive ion-beam facility in an experiment combining different detection methods tailored to the studied isotopes. These include either α-decay tagging or multireflection time-of-flight gating for isotope identification. The endpoint of the odd-even nuclear shape staggering in mercury was observed directly by measuring for the first time the isotope shifts and hyperfine structures of Hg177-180. Changes in the mean-square charge radii for all mentioned isotopes, magnetic dipole, and electric quadrupole moments of the odd-A isotopes and arguments in favor of I=7/2 s…

Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers : application of a multi-theory, dual-phase model and the contrib…

2018

Fruit and vegetable intake is insufficient in industrialized nations and long-haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi-theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective design with two waves of data collection spaced one week apart was adopted. Long-haul HGV drivers (N = 212) completed an initial survey containing theory-based measures of motivation (autonomous motivation, intention), social cognition (attitudes, su…
