The Employment Gap between immigrants and natives in European countries : The importance of integration policy and origin

We study the employment gap between immigrants and natives in 16 European countries and the effect of integration policies and country of origin. In this paper, we want to answer 3 main questions. First, is there employment gap between natives and immigrants? Using the European Social Survey, we found that employment gap exists for both male and female immigrants compare to natives because of their characteristics are different from natives. Second, how do various integration policies affect the employment probability of immigrants? Using Migration Integration Policy Index, the result shows that some integration policies are beneficial to immigrants but some are not. Lastly, how do various countries of origin characteristics affect the employment probability of immigrants? Using data from the World Bank and the United Nation Development Program, we found that Human development index and labor force participation rate of the origin country affects immigrants in positive effects of probability of being employed

Theory of Multiple-Detection Size-Exclusion Chromatography of Complex Branched Polymers

SEC separates complex branched polymers by hydrodynamic volume, rather than by molecular weight or branching characteristics. Equations relating the response of different types of detectors are derived including band broadening, by defining a distribution function N(M,Vh), the number of chains with molecular weight M and hydrodynamic volume Vh. While the true molecular weight distribution of complex polymers cannot be determined by SEC, irrespective of the detector used, the formalism enables multiple detection SEC data to be processed to both analyze the polymer sample and reveal mechanistic information about polymer synthesis. The formalism also shows how the true weight- and number-average molecular weight, and , can be obtained from correct processing of the hydrodynamic volume distributions
