Culture Clash or Culture Club? The Identity and Attitudes of Immigrants in Britain
There is economic evidence that diversity has consequences for economic performance (see Alesina and La Ferrara, 2005). This might have consequences for immigration policy - how many immigrants to allow into a country and from what cultural background. But, central to such a discussion is the pace of cultural assimilation among immigrants - this under-researched topic is the focus of this paper. It investigates the extent and determinants of British identity among those living in Britain and the views on rights and responsibilities in societies. We find no evidence for a culture clash in general, and one connected with Muslims in particular. The vast majority of those born in Britain, of whatever ethnicity or religion, think of themselves as British and we find evidence that third-generation immigrants are more likely to think of themselves as British than second generation. Newly arrived immigrants almost never think of themselves as British but the longer they remain in the UK, the more likely it is that they do. This process of assimilation is faster for those from poorer and less democratic countries, even though immigrants from these countries are often regarded as a particular cause for concern. Our analysis of rights and responsibilities finds much smaller differences in views between the UK-born and immigrants than within the UK-born population.Immigration, Identity, Assimilation
Magnetic levitation of large liquid volume
It is well known from experiments and industrial applications of cold crucible melting that an intense AC magnetic field can be used to levitate large volumes of liquid metal in the terrestrial conditions. The levitation confinement mechanism for large volumes of fluid is considerably different from the case of a small droplet, where surface tension plays a key role in constraining the liquid outflow at the critical bottom point. The dynamic interaction between the oscillatory motion of the free surface and the effects of turbulent flow is analysed using a unified numerical model, which describes the time dependent behaviour of the liquid metal and the magnetic field. The MHD modified k-? turbulence model is used to describe the mixing and damping properties at smaller scales not resolved by the macro model. The numerical multiphysics simulations suggest that it is possible to levitate a few kilograms of liquid metal in a cold crucible without requiring mechanical support from the container walls. Possible applications to the processing of reactive metals are discussed

Use of a Static Magnetic Field in Measuring the Thermal Conductivity of a Levitated Molten Droplet
Numerical models are used to analyze the complex behaviour of magnetically levitated droplets in the context of determining their thermophysical properties. We focus on a novel method reported in Tsukada et al. [4] which uses periodic laser heating to determine the thermal conductivity of an electromagnetically levitated droplet in the presence of a static DC field to suppress convection. The results obtained from the spectral-collocation based free surface code SPHINX and the commercial package COMSOL independently confirm and extend previous findings in [4]. By including the effects of turbulence and movement of the free surface SPHINX can predict the behaviour of the droplet in dynamic regimes with and without the DC magnetic field. COMSOL is used to investigate arbitrary amplitude axial translational oscillations when the spherical droplet is displaced off its equilibrium. The results demonstrate that relatively small amplitude oscillations could cause significant variation in Joule heating and redistribution of the temperature. The effect of translational oscillations on the lumped circuit inductance is analysed. When a fixed voltage drive is applied across the terminals of the levitation coil, this effect will cause the coil current to change and a correction is needed to the electromagnetic force acting on the droplet
The LIGO Open Science Center
The LIGO Open Science Center (LOSC) fulfills LIGO's commitment to release,
archive, and serve LIGO data in a broadly accessible way to the scientific
community and to the public, and to provide the information and tools necessary
to understand and use the data. In August 2014, the LOSC published the full
dataset from Initial LIGO's "S5" run at design sensitivity, the first such
large-scale release and a valuable testbed to explore the use of LIGO data by
non-LIGO researchers and by the public, and to help teach gravitational-wave
data analysis to students across the world. In addition to serving the S5 data,
the LOSC web portal (losc.ligo.org) now offers documentation, data-location and
data-quality queries, tutorials and example code, and more. We review the
mission and plans of the LOSC, focusing on the S5 data release.Comment: 8 pages, 1 figure, proceedings of the 10th LISA Symposium, University
