Lieu de résidence et discrimination salariale
2010
Ziel dieses Artikels ist es, die Lohnabweichungen zwischen Jugendlichen, die in sensiblen städtischen Zonen wohnen, am Ende ihrer Ausbildung und denjenigen, die zwar nicht in einer solchen Zone leben, die aber in städtischen Einheiten mit solchen Zonen wohnen, unter Berücksichtigung möglicher Barrieren beim Zugang zu bestimmten Beschäftigungen und insbesondere zu den Arbeitsplätzen von Führungskräften zu untersuchen. In Anknüpfung an Brown, Moon und Zoloth (1980) schlagen wir eine Zerlegung der Lohnabweichungen vor, bei der die Möglichkeit einer Differenzierung beim Zugang zu bestimmten Beschäftigungen entsprechend der Art des Stadtviertels, in dem die Jugendlichen wohnen, berücksichtigt wi…
Using R via PHP for Teaching Purposes: R-php
2006
This paper deals with the R-php statistical software, that is an environment for statistical analysis, freely accessible and attainable through the World Wide Web, based on R. Indeed, this software uses, as "engine" for statistical analyses, R via PHP and its design has been inspired by a paper of de Leeuw (1997). R-php is based on two modules: a base module and a point-and-click module. R-php base allows the simple editing of R code in a form. R-php point-and-click allows some statistical analyses by means of a graphical user interface (GUI): then, to use this module it is not necessary for the user to know the R environment, but all the allowed analyses can be performed by using the compu…
Recent Borexino results and prospects for the near future
2015
The Borexino experiment, located in the Gran Sasso National Laboratory, is an organic liquid scintillator detector conceived for the real time spectroscopy of low energy solar neutrinos. The data taking campaign phase I (2007 - 2010) has allowed the first independent measurements of 7Be, 8B and pep fluxes as well as the first measurement of anti-neutrinos from the earth. After a purification of the scintillator, Borexino is now in phase II since 2011. We review here the recent results achieved during 2013, concerning the seasonal modulation in the 7Be signal, the study of cosmogenic backgrounds and the updated measurement of geo-neutrinos. We also review the upcoming measurements from phase…
The Effects of Labor and Product Market Reforms: The Role of Macroeconomic Conditions and Policies
2018
The paper estimates the dynamic macroeconomic effects of labor and product market reforms on output, employment and productivity, and explores how these vary with prevailing macroeconomic conditions and policies. We apply a local projection method to a new dataset of major country- and country-sector-level reform shocks in various areas of labor market institutions and product market regulation covering 26 advanced economies over the past four decades. Product market reforms are found to raise productivity and output, but gains materialize only slowly. The impact of labor market reforms is primarily on employment, but it varies across types of reforms and depends on overall business cycle c…
A Theoretical Learning Model Combining Stochastic Cellular Automata and Economic Indicators to Simulate Land Use Change
2015
The study of change in land use has been included in territorial planning to inform spatial planners and policy makers of the possible developments they face in order to optimize future management decisions. In this paper the authors present the core of an original learning model coupling stochastic Cellular Automata and economic indicators to simulate the land use change. This model is an important step in building an “environmental virtual laboratory” to explore, explain and forecast land use change.
Le Equazioni Algebriche: i metodi risolutivi nella storia della matematica
2019
Nel presente lavoro si illustrerà un percorso didattico che usa la metodologia della storia della matematica nell’insegnamento. Si tratteranno, in particolare, i vari metodi risolutivi delle equazioni di primo e di secondo grado nella storia, dal metodo di falsa posizione degli egizi, ai metodi del completamento a quadrato o delle applicazioni delle aree nei greci, fino ai metodi risolutivi di René Descartes (Cartesio). I metodi geometrici dei greci e di Cartesio sono svolti con il software di geometria dinamica Geogebra. Il percorso si conclude con i riferimenti storici al rinascimento e alle formule risolutive delle equazioni di terzo e quarto grado e a Evariste Galois.
Palermo: Living Labs for Urban Regeneration
2016
The case of Palermo is described in this chapter as an example of Human Smart City (HSC) approach transferred to an extremely weak urban context in Southern Italy. The case focuses on the processes boosted through the Territorial Living Lab established in the city to tackle the topic of citizen participation in the solution of the main city challenges. It was based on a model of incremental and adaptive process of interaction, within a co-creative ecosystem, with the aim of improving housing quality. The model was shared by the players involved in the social innovation process. It would not have been possible without the Living Lab approach and the innovative momentum of design thinking tra…
Expression of a glucocorticoid receptor (D1GR1) in several tissues of the teleost fish Dicentrarchus labrax
2008
Since glucocorticoids have a role in maintaining the homeostatic status in fish, in the present paper mRNA expression (in situ hybridization) and tissue immunohistochemical localization of a glucocorticoid receptor (DlGR1) in several Dicentrarchus labrax organs are reported. Riboprobe and specific antibodies were prepared by using the DlGR1 that has been previously cloned and sequenced from peritoneal cavity leukocytes. Both mRNA and receptor were identified in head kidney, spleen, gills, intestine, heart and liver tissues. The functional roles of DlGR1 localization are discussed.
Fish welfare in aquaculture: From physiology to molecular activities and new tools for study innovative diets, social and spatial stress
2022
Guaranteeing a high quality of life for animals has recently become a matter of increasing concern. Welfare assessment has been well-developed for terrestrial species, mainly for those kept in captivity, but the current state of the art is less well-characterized for aquatic animals. The classical methodologies utilised to date, such as the kind of behavioural observation widely used for terrestrial animals, are not appropriate for improving our knowledge of the well-being of aquatic animals if used alone, mainly due to the large number of species and the difficulty of obtaining comparative results among the different taxa of interest. Among different approaches, the evaluation of internal …
