Can narratives of white identity reduce opposition to immigration and support for Hard Brexit? A survey experiment

Britain’s vote to leave the European Union highlights the importance of white majority opposition to immigration. This article presents the results of a survey experiment examining whether priming an open form of ethno-nationalism based on immigrant assimilation reduces hostility to immigration and support for right-wing populism in Britain. Results show that drawing attention to the idea that assimilation leaves the ethnic majority unchanged significantly reduces hostility to immigration and support for Hard Brexit in the UK. Treatment effects are strongest among UKIP, Brexit and white working-class voters. This is arguably the first example of an experimental treatment leading to more liberal immigration policy preferences

Efficacy of two endectoparasiticide products combining fipronil and (S)-methoprene or esafoxolaner with eprinomectin and praziquantel against fleas and intestinal helminths in cats naturally infested in Brazil

Eprinomectin and praziquantel, nematodicide and cestodicide compounds, are both combined with the insecticide and acaricide compounds fipronil and (S)-methoprene in Frontline® Protect/Broadline®, or esafoxolaner in NexGard® Combo. These topical feline endectoparasiticide products were tested for efficacy against fleas and intestinal helminths in a field trial in Brazil. Flea- and/or helminth-infested domestic cats were treated twice at a monthly interval following label instructions: 160 cats with Frontline® Protect/Broadline® and 165 cats with NexGard® Combo. The flea and intestinal helminth infestations were evaluated using comb counts and copromicroscopy, respectively before first treatment for baseline value, then 9 and 30 days after each treatment for fleas, and 9 days after each treatment for helminths. Multiparasitism was very frequent at baseline, as amongst the 325 included cats, 295, 280, 86 and 93 cats were at least infested with Ctenocephalides fleas, Ancylostoma, Toxocara and Dipylidium caninum, respectively. Efficacies were calculated by comparing the geometric means at baseline and at post-treatment timepoints for each parasite genus/species. Inclusive of both products and of all evaluation timepoints, the Ctenocephalides, Ancylostoma, Toxocara and D. caninum efficacies were at least 98.3%, 99.8%, 99.8% and 96.3%, respectively. No adverse reactions were observed, except for a few instances of mild, transient, and self-resolving hypersalivation occurring on the day of treatment in both groups. This field trial demonstrated high-level efficacy of Frontline® Protect/Broadline® and NexGard® Combo against major parasites of cats in Brazil

Antecedents of Trust among Citizens and Non-citizens in Qatar

Utilizing new survey data on social capital, we examine the determinants and locus of generalized trust among citizens and immigrants in Qatar, a small, heterogeneous, wealthy, and non-democratic country in which immigrants far outnumber citizens. Scholars of social capital have explored the development of generalized trust in many countries. Most of this attention has focused on the Western world, and little is known about how trust forms in other contexts. Our findings show that important insights resulting from research in developed democracies apply and have explanatory power in some of the very different environments present in Qatar, that these insights do not apply and have explanatory power in some of the other environments present in Qatar, that circumstances and experiences that characterize this array of environments can be identified and described in terms of variable attributes, and that linkages can be established between these attributes and particular antecedents of generalized trust
