Opis:
Migrant integration remains a continuous challenge in many EU countries, as shown by the retreat from multiculturalism and the concerns regarding Muslim migrants. In recent years, the increase in asylum-seekers has added further complexities to the issue. Meanwhile, volunteering is considered to be an important aspect of today’s society and a thermometer of civic well-being. Bringing together the field of migration studies and research on volunteering, we investigate whether volunteering would foster processes of integration and intercultural relations. We do so by presenting an innovative empirical study based on interviews and self-administered questionnaires conducted at two points in time over a period of about a year in a specific setting that brought together EU and third-country nationals in volunteering activities in six European contexts. Thus, we are able to provide an in-depth account of volunteering experiences and their effects on intercultural relations and processes of integration. The research highlights how volunteering fosters social interactions, intersecting with dynamics of inclusion. It is a valuable tool that strengthens the community as well as the process of social integration, helping to overcome the tensions and conflicts that persist in European societies. At the same time, we argue that volunteering cannot make up for all integration challenges since the process of societal integration requires a more comprehensive approach which includes tackling discrimination in structural integration.

Opis:
The numerical modelling of chloride diffusion in concrete structures requires an appropriate description of input parameters. The main inputs for the model are the diffusion coefficient of concrete and derived aging factor. The model itself can be susceptible to the values of these parameters because of the size of the finite elements and size of the time step. Due to the potential use in probabilistic calculations, which requires millions of simulations, it is desirable to create a highly optimized model. It is important to pay attention to the accuracy of the calculation, but also to its calculation time. The presented results show the possible limits of the finite element model of the diffusion in a concrete structure. This is demonstrated on the reference ordinary Portland cement mixture and 32 various binary and ternary concrete mixtures, which show a significant effect of different diffusion coefficients and aging factors on the overall convergence. This study provides guidance on which extreme material parameters, out of the potential range, may adversely affect model results.
