We achieved target recruitment and high brief intervention delivery if this occurred immediately after screening. Low rates of return for counselling and retention at follow-up were challenges for a definitive trial. Conversely, high consent rates for access to police data suggested at least some outcomes could be measured remotely.

To cope with awkward and unreliable information in daily life issues, the theory of interval-valued picture fuzzy set (IVPFS) is a useful idea to manage unpredictable and vague information. An IVPFS contains

Abstract:Using the UK Citizenship Survey for the years 2007-2010, this paper investigates how immigrants view immigration and how these views compare to the views of natives. Immigrants who have been in the UK longer are similar to natives in being opposed to further immigration, while recent immigrants are more in favour of further immigration. Labour market concerns do not play a large role for either immigrants or natives. However, there is some evidence that financial and economic shocks can increase anti-immigration sentiments.

While much is known regarding the effects of immigration for objective outcomes, relatively little is known regarding the effects for perceived well-being. By exploiting spatial and temporal variation in the net-inflows of foreign-born individuals across local areas in England, we examine the relationship between immigration and natives’ subjective well-being as captured by the General Health Questionnaire (GHQ). We find small negative effects overall but that an analysis of the main effects masks significant differences across subgroups, with relatively older individuals, those with below-average household incomes, the unemployed and finally those without any formal educational qualifications experiencing much more substantive well-being losses than others. These observed well-being differentials are congruent with voting patterns evident in the recent UK referendum on EU membership. We put forward perceived as opposed to actual labour market competition and social identity as two potential explanations for the negative well-being impacts of immigration for natives.
