Welfare chauvinism in the face of ethnic diversity:A vignette experiment across diverse and homogenous neighbourhoods on the perceived deservingness of native and foreign-born welfare claimants

The tenuous relationship between ethnic diversity and welfare solidarity has become a central focus in sociological and political inquiry. Yet, the question whether ethnic composition of the residential environment affects welfare chauvinism (favouring an encompassing welfare state that is preserved for ingroup members) has remained fundamentally unanswered. This article integrates extensive experimental data on welfare solidarity with hypothetical, unemployed persons from domestic and foreign origin among 23,015 native participants (to isolate welfare chauvinism), and detailed registry data (on the residential neighbourhood of these participants) from the Netherlands. This combination of contextual and experimental data allows us to test rivalling theoretical arguments on the relationship between ethnic diversity and welfare chauvinism, namely conflict, contact, and constrict theory. The outcomes of this enriched vignette survey experiment show that ethnic diversity has a specific and sizeable effect on welfare chauvinism under a range of model specifications. Diverse neighbourhoods drive down natives’ support for welfare distribution with migrants but not with natives. Ethnic diversity thereby stimulates the deservingness gap between natives and migrants, i.e., welfare chauvinism. We discuss the implications of these findings for conflict, contact, and constrict theory

examples of monometallic, homobimetallic and heterobimetallic complexes

Mononuclear PtII and the first dinuclear PtII complexes along with a cyclometalated heterobimetallic IrIII/PdII complex bearing mesoionic carbene donor ligands are presented starting from the same bis-triazolium salt. The mononuclear PtII complex possesses a free triazole moiety which is generated from the corresponding triazolium salt through an N-demethylation reaction, whereas the mononuclear IrIII complex features an unreacted triazolium unit

Comparison of deep-water-parameter-based wave overtopping with wirewall field measurements and social media reports at Crosby (UK)

Wave overtopping formulae, which often underlie coastal hazard early warning systems, are typically parameterised using wave conditions at the toe of the structure. For very shallow conditions where significant wave breaking occurs over the foreshore, this usually requires computationally-demanding numerical models—and practitioners skilled in their application—to accurately transform offshore waves to the structure toe. An additional concern is that overtopping formulae are scarcely validated in the field due to the very limited availability of in-situ overtopping data obtained at actual structures. Here, we validate a set of deep-water-parameter-based formulae for mean overtopping discharge (q) at smooth slopes, which remove the need for nearshore measurements or additional numerical modelling but require that a single representative foreshore slope angle (m) be defined. The validation is carried out against field data gathered at Crosby (UK) using two novel approaches: i) a new overtopping measurement system called “WireWall”; and ii) crowd-sourced data in the form of overtopping images obtained from a community Facebook page (social media). A method is introduced to define m for irregular bathymetries, based on the location where the local water depth is equal to the offshore significant wave height. The overtopping formulae proved accurate—with estimates of q being within a factor of 4 of observations—when compared to both 1-h averaged and 15-min averaged overtopping data, suggesting that the approach can be used for both design and assessment and now-casting hazard information. Finally, hindcasts made using the newly validated formulae for the events reported by the community indicate that q can exceed 10 l/s/m under yearly winter conditions, posing a serious hazard to pedestrians. This highlights the pressing need to update the current hazard warning system at Crosby, which estimates q to be a factor of 3 lower than the deep-water-parameter-based approach, on average
