The academic evidence regarding immigration is overwhelmingly positive
While national politicians continue to speak about immigration in negative terms, the academic evidence is overwhelmingly positive. Migrants tend to be highly-skilled on average, contribute substantially to the economy, and do not compete with natives for social housing. Moreover, there is no evidence that crime rates have been on the rise as a result of new immigration waves. Neli Demireva writes that there is a real danger the immigration debate will turn sour and have spill-over effects in unexpected places

dissertationThe lanthanides that make up the f-block of the periodic table remain fairly unexplored experimentally such that there is a need for thermochemical information regarding these elements to better understand their reactivity and properties, including, for example, their potential usefulness as catalysts in organometallic and oxidation catalysis. In addition, these heavy elements are difficult to describe theoretically because of spin-orbit and relativistic effects and the many electronic configurations possible from the 4f electrons. Accurate thermochemistry measured from gas-phase experiments, where systems can be probed in isolation from solvent or substrate molecules, can serve as useful benchmarks for evaluating theoretical methods. The work described in this dissertation focuses on examining the gas-phase reactivity and thermochemistry of the lanthanide gadolinium cation (Gd+). Gd+ is found in the middle of the lanthanide series and has a 4f76s15d1 ground state valence electron configuration. This configuration (with two non-4f electrons) is unusual compared with most lanthanide cations, which typically have 4fn6s1 configurations (n corresponding to the remaining valence electrons). Guided ion beam tandem mass spectrometry (GIBMS) is used here to investigate and measure the thermochemistry of the gas-phase activation of H2, O2, and CO2 by Gd+. Potential energy surfaces for the oxidation reactions with O2 and CO2 are characterized in great detail from these experiments. Quantum chemical calculations are performed and provide insight into the electronic states of the species probed in the experiments and a detailed understanding of the reaction mechanisms. Periodic trends are elucidated, where results indicate that Gd+ generally behaves more similarly to the group 3 transition metal cations scandium (Sc+) and yttrium (Y+) than to most lanthanide cations, which is attributable to similarities and differences in the electronic ground states of these ions, respectively. The extensive thermochemistry determined for Gd+ in this work can serve as valuable standards for comparing theoretical calculations against. Moreover, the mechanistic insights provided by these studies for the activation of H2, O2, and CO2 by Gd+ can potentially be useful in understanding the activation in analogous reactions with other metals, where this information can potentially lead to insight beneficial for the design of more effective catalysts
An Examination of Ethnic Hierarchies and Returns to Human Capital in the UK
This article focuses on the returns to human capital of migrants and minorities in the UK. The question of whether skills and qualifications are properly utilized is very pertinent given the global competition for skilled migrants and the aim of European and British markets to attract such workers. Using data from Understanding Society (2009 to 2017) we find that there is a clear evidence of ethnic hierarchies with black Caribbean and black African minorities generally most disadvantaged, while other white UK-born have the best outcomes compared to the white British. Western migrants generally do very well, but new EU migrants have high levels of employment, and low returns to their qualifications and relatively high levels of over-qualification. Foreign qualifications are generally discounted, and more so for migrants with less certain legal status or low language skills. Public sector employment plays an important role and is associated with the higher economic placement of migrants and minorities in the UK. There are some worrying trends however. Highly skilled migrants, particularly black migrants as well as those from Eastern Europe, come in with high qualifications, but their jobs do not match their skill levels
Ethnic and migrant penalties in job quality in the UK: the role of residential concentration and occupational clustering
Migrants and ethnic minorities in the UK are found to be disadvantaged in their access to work and earnings, but little is known about the characteristics of the jobs they occupy. This paper studies whether migrants and UK-born ethnic minorities attain similar jobs compared to their white British peers by clustering 17 indicators of job quality – covering intrinsic quality, work-life balance, monetary rewards, and employment conditions – into 5 latent classes. We find that non-white migrants are clustered in the worst jobs, while white migrants do relatively well. UK-born ethnic minorities are indeed less likely to work on the best jobs, but the type of disadvantage differs strongly between ethnic groups. Local deprivation drives some of the worse job quality of UK-born minorities while selection into lower-quality occupations and sectors drives much of the disadvantage of migrants. Co-ethnic support and particularly an economically stronger co-ethnic community in the locality can help shield ethnic minorities from the worst jobs, while ethnic niches in the occupation are associated with low-quality work. Finally, working in migrant-heavy occupations is associated with somewhat lower job quality; primarily affecting other migrants in a possible race to the bottom
Returns to Human Capital and the Incorporation of Highly-Skilled Workers in the Public and Private Sector of Major Immigrant Societies: An Introduction
Across the major immigrant societies of the European Union, EU-15 countries, migrants and minorities still experience economic disadvantage. This failure of economic integration poses significant questions about the utilization of human capital, the management of mobility and the competitiveness of European labour markets (Cameron, 2011; OECD, 2017). Using a variety of datasets, this special issue pushes the debate forward in several ways. We will consider the integration outcomes of both migrants and second generation minority members in comparison to majority members. Labour market outcomes will be considered broadly: the probability of employment but also overqualification will be taken into account. Offering both analysis of single country cases and a cross-national comparison, the special issue will build a comprehensive picture of the factors associated with labour market disadvantage of migrant men and women, and their descendants—particularly, differential returns to foreign qualifications and educational credentials, differences between public and private sectors placements, and where possible the period of the economic crisis will be examined as well
