Conditioning family-life at the intersection of migration and welfare: the implications for ‘Brexit families'

European Free Movement (EFM) was central to the referendum on the UK’s membership of the EU. Under a ‘hard’ Brexit scenario, it is expected that EFM between the UK and the EU will cease, raising uncertainties about the rights of existing EU citizens in the UK and those of any future EU migrants. This article is concerned with the prospects for family rights linked to EFM, which, we argue impinge a range of families – so-called ‘Brexit families’ (Kofman, 2017) - beyond those who are EU-national families living in the UK. The article draws on policy analysis of developments in the conditionality attached to the family rights of non-EU migrants, EU migrants and UK citizens at the intersection of migration and welfare systems since 2010, to identify the potential trajectory of rights post-Brexit. While the findings highlight stratification in family rights between and within those three groups, the pattern is one in which class and gender divisions are prominent and have become more so over time as a result of the particular types of conditionality introduced. We conclude by arguing that with the cessation of EFM, those axes will also be central in the re-ordering of the rights of ‘Brexit families’

Impact of foot-and-mouth disease on mastitis and culling on a large-scale dairy farm in Kenya

Foot and mouth disease (FMD) is a highly transmissible viral infection of cloven hooved animals associated with severe economic losses when introduced into FMD-free countries. Information on the impact of the disease in FMDV-endemic countries is poorly characterised yet essential for the prioritisation of scarce resources for disease control programmes. A FMD (virus serotype SAT2) outbreak on a large-scale dairy farm in Nakuru County, Kenya provided an opportunity to evaluate the impact of FMD on clinical mastitis and culling rate. A cohort approach followed animals over a 12-month period after the commencement of the outbreak. For culling, all animals were included; for mastitis, those over 18 months of age. FMD was recorded in 400/644 cattle over a 29-day period. During the follow-up period 76 animals were culled or died whilst in the over 18 month old cohort 63 developed clinical mastitis. Hazard ratios (HR) were generated using Cox regression accounting for non-proportional hazards by inclusion of time-varying effects. Univariable analysis showed FMD cases were culled sooner but there was no effect on clinical mastitis. After adjusting for possible confounders and inclusion of time-varying effects there was weak evidence to support an effect of FMD on culling (HR = 1.7, 95% confidence intervals [CI] 0.88-3.1, P = 0.12). For mastitis, there was stronger evidence of an increased rate in the first month after the onset of the outbreak (HR = 2.9, 95%CI 0.97-8.9, P = 0.057)

Brexit’s Effect on Citizens, Human Rights & Immigration

This report records the roundtable on “Brexit’s Effect on Citizens, Human Rights and Immigration” organised by Dr Adrienne Yong on 11 June 2019 at City, University of London funded by the Higher Education Innovation Fund (HEIF) 2018/19. Speakers included: • Hannah Wilkins (House of Commons Library) • Blanca Grey (Home Office)1 • Paul Erdunast (Immigration Law Practitioner’s Association - ILPA) • Christopher Desira (Seraphus Solicitors) • Nicole Masri (Rights of Women) • Ollie Persey (Public Law Project) • Katarzyna Zagrodniczek (East European Resource Centre) • Mihai Calin Bica (Roma Support Group) • Dr Adrienne Yong (City, University of London) • Dr Michaela Benson (Goldsmiths, University of London) • Madeleine Sumption (Migration Observatory) • Sheona York (Kent Law Clinic) A host of unique legal questions were raised in the aftermath of the UK’s referendum result where the electorate voted in favour of leaving the EU on the 23 June 2016. Opinion has been split as to whether the UK and EU have indeed struck a fair deal for citizens, with arguments that citizens have been used as bargaining chips throughout the process to achieve a deal. As negotiations progressed towards the original mandated date of withdrawal, 29 March 2019, various schemes emerged to handle post-Brexit immigration of EU citizens in the UK and reciprocal arrangements for British citizens in the EU. This is now reflected in the EU Settlement Scheme, the Immigration and Social Security Co-ordination Bill, and the reciprocity agreed with EU Member States as to British citizens in the EU. These issues and more were discussed at the roundtable

High transport critical current density and large Hc2 and Hirr in nanoscale SiC doped MgB2 wires sintered at low temperature

We report a systematic study on the effect of sintering temperature on the phase formation, critical current density, upper critical field and irreversibility field of nanoscale SiC doped MgB2. Bulk and Fe sheathed wires doped with different nano-SiC particle sizes have been made and heat treated at temperatures ranging from 580 to 1000 °C. A systematic correlation between the sintering temperature, normal state resistivity, RRR, Jc, Hc2, and Hirr has been found in all samples of each batch. Samples sintered at a lower temperature have a very fine and well consolidated grain structure while samples sintered at a high temperature contain large grains with easily distinguishable grain boundaries. Low temperature sintering resulted in a higher concentration of impurity precipitates, larger resistivity, higher Jc up to 15 T and lower Tc values. These samples show higher Hc2 and Hirr at T near Tc but lower Hc2 near T = 0 than samples sintered at high temperature. It is proposed that huge local strains produced by nano-precipitates and grain boundary structure are the dominant mechanism responsible for higher Hc2 at T near Tc. However, higher impurity scattering due to C substitution is responsible for higher Hc2 in the low temperature regime for samples sintered at a higher temperature. In addition to high Hc2, it is also proposed that the large number of nano-impurities serve as pinning centres and improve the flux pinning, resulting in higher Jc values at high magnetic fields up to 15 T
