Deep and Proximate Determinants of the World Income Distribution

2019

This paper studies the deep and proximate determinants of the evolution of the cross-country distribution of GDP per worker in the period 1960–2008 by a novel method based on an information criterion. We find that countries of our sample follow three distinctive growth regimes identified by two deep determinants, namely life expectancy at birth in 1960 and the share of Catholics in 1965, and that each regime is characterized by non-linearities. Growth regimes appear to be the main cause of the increased inequality and polarization, while technological catch-up, proxied by the initial level of GDP per worker, acts in the opposite direction. Finally, human capital marginally reduces polarizat…

Competition between chain scission and branching formation in the processing of high-density polyethylene: effect of processing parameters and of sta…

2009

Two samples of high-density polyethylene with different molecular weight were processed in a batch mixer and the rheological and structural properties were investigated. In particular, the effect of different processing parameters and the eventual presence of different stabilizers were evaluated. Actually, two reactions may occur during processing: branching/crosslinking or chain scission. The results indicate that when the processing conditions promote a scarce mobility of the macromolecular chains (lower temperatures, lower mixing speed, and higher molecular weight), branching is more favored than chain scission. On increasing the mobility of the chain (higher temperature, higher mixing s…

Hyaluronan-coated polybenzofulvene brushes as biomimetic materials

2016

Hyaluronic acid (HA) forms pericellular coats in many cell types that are involved in the early stages of cell adhesion by interacting with the CD44 receptor. Based on the largely recognized overexpression of the CD44 receptor in tumor tissues, a polybenzofulvene molecular brush has been enveloped into hyaluronan shells to obtain a tri-component polymer brush (TCPB) composed of intrinsically fluorescent backbones bearing nona(ethylene glycol) arms terminated with low molecular weight HA macromolecules. The nanoaggregates obtained in TCPB water dispersions were characterized on the basis of dimensions, zeta potential, and in vitro cell toxicity. This biomimetic multifunctional material beari…

L'applicazione della disciplina delle pratiche commerciali scorrette nel 'macrosettore credito e assicurazioni'

2011

Quello che viene denominato "macrosettore credito e assicurazioni" costituisce uno degli ambiti nei quali l'Autorità garante della concorrenza e del mercato ha esercitato con maggiore frequenza le proprie competenze in materia di pratiche commerciali scorrette. Il saggio, affrontata in via preliminare la questione della stessa applicabilità della disciplina al macrosettore, esamina criticamente gli orientamente emersi nella prassi, individuandovi talune costanti dell'interpretazione fornita dall'Autorità ai concetti-chiave che caratterizzano la fattispecie "pratiche commerciali scorrette" e determinano l'estensione della relativa disciplina.

In vitro evaluation of the influence of bone cortical thickness on the primary stability of conventional- and short-sized implants

2022

Made available in DSpace on 2022-04-28T19:50:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01 Background: The aim of this in vitro study was to evaluate the influence of the cortical thickness on the primary stability of short and conventional-sized implants with two types of prosthetic connection. Material and Methods: Seventy-two implants were used. These implants were placed in polyurethane blocks that simulated low-density bone tissue (type IV bone), with two bone cortical heights (type I bone): 1mm and 3mm. The implants were divided into 6 groups with 12 implants each according to the type of prosthetic connections (external-hexagon -EH and morse taper- MT) and implant s…

ICT demand behaviour: An international comparison

2009

This study aims to provide some empirical explanations for the gaps in ICT diffusion between industrialized countries, especially European countries vis-à-vis the United States. The panel data cover eleven OECD countries: Austria, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands, Spain, the United Kingdom and the United States. These annual macroeconomic data span the 1981-2005 period.The analysis provides some original results: (i) the impact on ICT diffusion of the level of education and market rigidities has changed over time. The correlation of ICT diffusion, positive with the level of education and negative with market rigidities, increased over time (in absolute terms)…

Incidence de la clarification des moûts de raisin sur les fermentescibilltés alcoolique et malolactique

1993

<p style="text-align: justify;">Des essais de débourbage en vinification en blanc, réalisés de 1988 à 1992, mettent en évidence le rôle important joué par la teneur en macromolécules solubles dans le moût de raisin. Les moûts de faible turbidité conduisent en effet à des fermentations alcooliques lentes en relation avec de faibles populations levuriennes. Il est également confirmé que la libération de polysaccharides exocellulaires par les levures au cours de la fermentation alcoolique est d'autant plus élevée que le moût de départ a été fortement appauvri en colloïdes de raisin. Par contre, ce sont dans les lots les plus clarifiés que l'on observe la meilleure fermentescibilité malol…

Economic policy uncertainty effects for forecasting future real economic activity

2018

Recently introduced measures for Economic Policy Uncertainty (EPU) included in the data from 1997 - 2016 have a role in forecasting out-of-sample values for the future real economic activity for both the euro area and the UK economies. The inclusion of EPU measures, either for the US, the UK or for overall European economies, improves the forecasting ability of models based on standard financial market information, especially for the period before the 2008 global crisis. However, during and after the crisis period, the slope of the yield curve and excess stock market returns improves the out-of-sample forecast performance the most compared to an AR-benchmark model. Hence, the EPU informatio…
