Migration and imperfect labor markets: theory and cross-country evidence from Denmark, Germany and the UK

2014

We investigate the labor market effects of immigration in Denmark, Germany and the UK, three countries which are characterized by considerable differences in labor market institutions and welfare states. Institutions such as collective bargaining, minimum wages, employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks, and, hence, the labor market effects of immigration. We employ a wage-setting approach which assumes that wages decline with the unemployment rate, albeit imperfectly. We find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock. In Germany immigration i…

Comparative studies of water governance: a systematic review

2018

[EN] Governance is key to tackling water challenges and transforming water management under the increasing pressures of competing water uses and climate change. Diverse water governance regimes have evolved in different countries and regions to regulate the development and management of water resources and the provision of water services. Scholars and policy analysts have been comparing these water governance regimes to analyze elements and processes, to assess performance, or to draw lessons. Although the number of such studies has increased since the 1980s, no comprehensive synthesis exists. We present such a synthesis by conducting a systematic review of the emerging field of comparative…

Splitting of the surface phonon modes in wurtzite nanowires

2013

We analyze the surface optical modes of GaN nanowires (NW) and perform a comparative study with the characteristics expected for other polar NWs. The theoretical analysis of the modes is performed within the context of the effective medium theory that takes into account the dipolar interaction between neighboring NWs (Maxwell-Garnett approximation). It is shown that deviations of the exciting light from the NWs axis, which coincides with the wurtzite c-axis, result in the anticrossing of two distinct surface phonon branches, leading to their splitting in axial and planar components and the appearance of two peaks in the Raman spectra. Additional calculations are performed that determine th…

A comparative study on the dynamic response of three semisubmersible floating offshore wind turbines

2019

Abstract Currently, there is a great interest to globally develop offshore wind energy due to the greenhouse effect and energy crisis. Great efforts have been devoted to develop reliable floating offshore wind energy technology to exploit the wind energy resources in deep seas. This paper presents a comparative study of the dynamic response of three different semisubmersible floating wind turbine structures. All the three platforms support the same 5MW wind turbine. The platforms examined are: a V-shaped Semi, an OC4-DeepCwind Semi and a Braceless Semi at 200 m water depth. A dynamic analysis is carried out in order to calculate and compare the performance of these platforms. The comparison…

Un’esperienza educativa di trasposizione culturale nella scuola primaria

2015

La nostra ricerca vuole mostrare come lo studio di approcci sviluppati in diversi contesti culturali può essere importante per riflettere sulle nostre pratiche didattiche e per progettare nuove sperimentazioni nelle classi. In particolare abbiamo studiato le rappresentazioni grafiche usate per descrivere e risolvere problemi additivi nella scuola primaria in Russia e Cina. In questo articolo introdurremo l’idea di trasposizione culturale che sarà anche esemplificata attraverso la descrizione e analisi di due percorsi didattici realizzati in una II e in una V primaria italiane.

What is your couple type? Gender ideology, housework and babies

2014

This paper examines the consistency between gender equality in opinions and attitudes and equality in the division of household labor by building a typology of respondents that combines two indexes for two dimensions of gender equality. The typology identifies four types of couples: gender unequal attitudes and gender unequal housework sharing, gender equal attitudes and gender unequal housework sharing, gender unequal attitudes and gender equal housework sharing, gender equal attitudes and gender equal housework sharing. We assess the impact of the typology on the likelihood of a new childbirth, using two-wave panel data of the Bulgarian, French and Hungarian Generations and Gender Surveys…

Data from: The evolution of colour pattern complexity: selection for conspicuousness favours contrasting within-body colour combinations in lizards

2016

Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based colours generates local chromatic contrast, we hypothesized that selection may favour the co-occurrence of lateral and ventral contrasting patc…
