The disability employment gap in European countries: What is the role of labour market policy?

Across Europe, the labour market participation of persons with disabilities remains lower than that of persons without a disability. Our research examines this disability employment gap, looking specifically at its variation by country and gender. Additionally, we test the influence of labour market policies – testing both the social investment perspective and the welfare scepticism perspective – on the size of the gap, in an effort to determine whether a more generous welfare state raises or lowers the employment rate of people with disabilities. Using the European Union Statistics on Income and Living Conditions (EU-SILC), we show that Southern European countries have the smallest disability employment gap. Whereas stricter employment protection legislation is found to be beneficial for people with disabilities on the labour market, other labour market policies specifically intended to benefit this group do not strongly affect their chances on the labour market. These findings support the social investment perspective and show that social policies can have a positive effect on the employment of people with disabilities

Local and nonlocal contributions to the linear spectroscopy of light-harvesting antenna systems

In this paper the circular dichroism and absorption spectra of the LH2 complex of Rhodopseudomonas acidophila, for which the atomic structure is known, are analyzed. We show that an analysis based on the distribution of the excitations in real space, and their correlations, to unravel the relation between the atomic structure of the light-harvesting complex and its excitonic properties, is particularly successful. Starting from molecular expressions for the linear susceptibility, we demonstrate that linear spectra can be viewed as originating from the product of coherence correlation functions and geometric structure factors. Effects of homogeneous and inhomogeneous broadening can be incorporated in a natural way and lead to a definition of exciton length as the distance over which coherence correlation functions decay. 1

Bank debt and trade credit for SMEs in Europe: firm-, industry-, and country-level determinants

This paper examines differences in the ability to obtain capital—bank loans and trade credit—between firms, industries, and countries using survey data on European small and medium-sized enterprises (SMEs) from 2009 to 2014. The results show that firm age and firm size are positively linked to SMEs’ access to bank loans, but only firm size is positively related to the provision of trade credit. The results also provide em- pirical support for a complementary rather than a sub- stitutive effect between bank loans and trade credit. Manufacturing SMEs have a significantly higher likeli- hood of receiving bank loans and trade credit than non- manufacturing SMEs. We find differences across coun- tries in terms of the relevance of firm age and firm size for obtaining capital. In addition, we point at specific country-level variables that explain why obtaining credit is easier in some countries. We perform additional anal- yses to confirm our baseline results and provide direc- tions for future research.Coherent privaatrech

Climate model boundary conditions for four Cretaceous time slices

International audienceGeneral circulation models (GCMs) are useful tools for investigating the characteristics and dynamics of past climates. Understanding of past climates contributes significantly to our overall understanding of Earth's climate system. One of the most time consuming, and often daunting, tasks facing the paleoclimate modeler, particularly those without a geological background, is the production of surface boundary conditions for past time periods. These boundary conditions consist of, at a minimum, continental configurations derived from plate tectonic modeling, topography, bathymetry, and a vegetation distribution. Typically, each researcher develops a unique set of boundary conditions for use in their simulations. Thus, unlike simulations of modern climate, basic assumptions in paleo surface boundary conditions can vary from researcher to researcher. This makes comparisons between results from multiple researchers difficult and, thus, hinders the integration of studies across the broader community. Unless special changes to surface conditions are warranted, researcher dependent boundary conditions are not the most efficient way to proceed in paleoclimate investigations. Here we present surface boundary conditions (land-sea distribution, paleotopography, paleobathymetry, and paleovegetation distribution) for four Cretaceous time slices (120 Ma, 110 Ma, 90 Ma, and 70 Ma). These boundary conditions are modified from base datasets to be appropriate for incorporation into numerical studies of Earth's climate and are available in NetCDF format upon request from the lead author. The land-sea distribution, bathymetry, and topography are based on the 1°×1° (latitude × longitude) paleo Digital Elevation Models (paleoDEMs) of Christopher Scotese. Those paleoDEMs were adjusted using the paleogeographical reconstructions of Ronald Blakey (Northern Arizona University) and published literature and were then modified for use in GCMs. The paleovegetation distribution is based on published data and reconstructions and consultation with members of the paleobotanical community and is represented as generalized biomes that should be easily translatable to many vegetation-modeling schemes

Graph Layouts by t‐SNE

We propose a new graph layout method based on a modification of the t-distributed Stochastic Neighbor Embedding (t-SNE) dimensionality reduction technique. Although t-SNE is one of the best techniques for visualizing high-dimensional data as 2D scatterplots, t-SNE has not been used in the context of classical graph layout. We propose a new graph layout method, tsNET, based on representing a graph with a distance matrix, which together with a modified t-SNE cost function results in desirable layouts. We evaluate our method by a formal comparison with state-of-the-art methods, both visually and via established quality metrics on a comprehensive benchmark, containing real-world and synthetic graphs. As evidenced by the quality metrics and visual inspection, tsNET produces excellent layouts
