Labour Contract Regulations and Workers' Wellbeing: International Longitudinal Evidence
All industrialized countries have Employment Protection Legislation (EPL) for permanent workers and Restrictions on the use of Temporary Employment (RTE). The (ambiguous) effects of these on the levels of employment and unemployment have been extensively studied, but nothing is known empirically about their well-being implications. Using longitudinal data from the European Community Household Panel, the author conducts the first study of the link between both EPL and RTE and workers' wellbeing. The results provide evidence that both permanent and temporary employees gain from reforms that ease restrictions on temporary employment but leave firing costs for permanent workers unchanged. This finding contrasts with common claims found in the political economy literature.employment protection legislation, temporary employment, job satisfaction
What Do Unions Do to Temporary Employment?
In the EU, one in seven employees work on temporary contracts associated with lower pay and less training. Using workplace-level data from 21 countries, I show that, in contrast with previous evidence for the US, unionized workplaces are more likely to use temporary employment across Europe. To address the endogeneity of unions, I then use a British dataset and exploit variation over time and across occupations to control for workplace unobserved heterogeneity. This confirms that unions contribute to creating contract duality in the labour market and thus do not limit the ability of firms to adjust employment through flexible contracts.temporary employment, unions, panel data
Effects of the antiozonant ethylenediurea (EDU) on Fraxinus ornus L.. The role of drought
Ethylenediurea (EDU) is a synthetic chemical known to protect plants from the phytotoxic effects of tropospheric ozone (O3). Although many studies have proposed the use of EDU for studying the O3 effects under field conditions, its mechanism of action is not fully understood, and it is unclear whether it exerts a specific antiozonant action, or if it may also interact with other oxidative stresses. The aim of this work was to evaluate the effect of EDU on forest species in a Mediterranean environment where, during summer, vegetation is exposed to multiple oxidative stresses, such as O3 and drought. The experiment was conducted on Fraxinus ornus L. (Manna ash) plants growing in six mesocosms, three maintained under full irrigation, while the other three were subjected to drought for 84 days. In each mesocosm, three plants were sprayed every 15 days with 450 ppm EDU. Gas exchange and chlorophyll "a" fluorescence measurements carried out through the experimental period highlighted that EDU did not affect stomatal conductance and had an ameliorative effect on the functionality of drought-stressed plants, thus suggesting that it may act as a generic antioxidant. The implications of these findings for the applicability of EDU in field studies are discussed
Use of satellite images for broad-scale modelling of conservation areas for wolves in the Carpathian Mountains, central Europe
This study analysed the spatial structure of the Carpathian Mountains, in Central Europe, considering it a unit that extends across national boundaries, and assessing the suitability of areas were wolves could be conserved. Physical characteristics of the area were extracted from NOAA-AVHRR NDVI. A set of 9 images from different periods of the year was used to parameterise the phenological variability of the area. Digital maps of road networks, human settlements and a DEM were integrated in a GIS. Locations of wolf presence
were used to extract “optimal” environmental characteristics that served as reference for estimating the degree of suitability over the whole area. Results show that most of the Carpathian Mountains are highly suitable for the wolf and that highly suitable areas are actually inhabited by the present population of wolf. These are also the area most phenologically stable
