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)…

Effect of an insect growth regulator (halofenozide) on the cuticular hydrocarbons of Culex pipiens larvae

2013

The cuticular hydrocarbons of the fourth-instar larvae of Culex pipiens aged one and six days were analysed by gas chromatography and gas chromatography-mass spectrometry. The effect of an insect growth regulator (halofenozide = RH-0345) on the cuticular hydrocarbons was evaluated using newly moulted fourth-instar larvae of C. pipiens, at the lethal concentrations (LC50 = 12.58 and LC90 = 28.58 mu g/l). A previous study revealed that RH-0345 is toxic to larvae of C. pipiens by induction of precocious larval moulting. Several cuticular hydrocarbons (CHCs) were identified and many of the other compounds remained unknown. Our data show that the CHC classes consisted of n-alkanes (C23-C29) and …

Manufacturing export performance and public capital: an analysis by country technology position

2021

The objective of this paper is to examine the relationship between public capital and manufacturing export performance. It also aims at investigating whether this relationship depends on the proximity of a country's technology frontier. To achieve this, we adopted a methodology that estimates the elasticities of public capital as a non-rival factor in a model that considers factor intensity as a mechanism of industrial development. We use an interaction model with panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that in countries far from the technology frontier, public capital accumulation is an element of industrial development as opposed to co…

Il ruolo educativo della psicomotricità in età evolutiva: il vissuto dei Genitori e dei Docenti

2018

La nozione di "schema corporeo" a partire dagli anni Sessanta, trova spazio tra gli obiettivi e le finalità riferiti all'educazione motoria e fisica a scuola. Attraverso i contributi della psicomotricità di P. Vayer, P. Aucouturier, J. Le Boulch, si fanno strada principi educativi e metodologici che vedono l'Educazione del e attraverso il corpo quale strumento fondamentale di conoscenza di sé, di un metodo di apprendimento che coinvolge in egual misura l'emozionale e il cognitivo. Il suo graduale riconoscimento quale centro di identità da cui parte ogni esperienza, ha dato luogo ad una crescente attenzione alle potenzialità conoscitive del corpo, ma anche di quelle espressive delle emozioni…

Public Libraries – Facilitators of Information Society and e- Inclusion in Latvia

2014

Abstract The economic growth and national competitiveness is closely correlated with the development of information society. In the last few years the role of public libraries has significantly increased and libraries have greatly contributed to the improvement of information society in Latvia. The usage of library services had never been as high as they were in 2011 – 42% of the population were active library users and 90% of them used the Internet. Nowadays, the public library network in Latvia provides a powerful network of information, knowledge and community centres and they are highly demanded by society.

Non-crossing quantile regression via monotone B-spline varying coefficients

2019

Quantile regression can be used to obtain a nonparametric estimate of a conditional quantile function. The presence of quantile crossing, however, leads to an invalid distribution of the response and makes it dicult to use the tted model for prediction. In this work, we show that crossing can be alleviated or completely eliminated by explicit modeling of the regression coecients as a function of the percentile values in (0,1). We illustrate the approach via a wellknown dataset by emphasizing dierences with respect to the competitors.

The reactivity of neonatal rabbits to the mammary pheromone as a probe for viability

2012

International audience; Newborn rabbits depend on a daily nursing interaction with the mother to gain milk and to survive. During this interaction, they localise and seize the nipples displaying a typical behaviour triggered by maternal odour cues. The mammary pheromone constitutes such a signal in domestic rabbits: it elicits sucking-related movements in more than 90% of the pups. However, some newborns remain unresponsive to the presentation of the pheromone, even pups apparently healthy and highly motivated to suck. The main goal of the present study was therefore to explore the link between the unresponsiveness of rabbit pups to the mammary pheromone and their growth and survival in bre…

Inhibition of Rac1 signaling by lovastatin protects against anthracycline-induced cardiac toxicity

2011

Normal tissue damage limits the efficacy of anticancer therapy. For anthracyclines, the clinically most relevant adverse effect is cardiotoxicity. The mechanisms involved are poorly understood and putative cardioprotectants are controversially discussed. Here, we show that the lipid-lowering drug lovastatin protects rat H9c2 cardiomyoblasts from doxorubicin in vitro. Protection by lovastatin is related to inhibition of the Ras-homologous GTPase Rac1. It rests on a reduced formation of DNA double-strand breaks, resulting from the inhibition of topoisomerase II by doxorubicin. Doxorubicin transport and reactive oxygen species are not involved. Protection by lovastatin was confirmed in vivo. I…
