Applying Bourdieu’s capital-field-habitus framework to migrant careers: Taking stock and adding a transnational perspective

HRM and Migration scholars increasingly employ Bourdieu’s concepts of capitals, fields and habitus to explain the interrelationships between migrant careers and context. Both literatures employ a Bourdieusean framework to examine devaluation of migrant capitals in host nations and migrant responses to such devaluation. However, their explanations are based on different assumptions of context. HRM literature regards migrants as confined to the host nation context, whereas Migration literature places them in a transnational context, spanning both originating and host nations. In this conceptual paper, we argue for integrating transnational perspectives into HRM literature to offer a more accurate portrayal of contemporary migrant lives, and to capture greater nuance in migrant career experiences. We seek to expand the conceptual lexicon to support new conceptualisations of transnational context, and to explore how locating a Bourdieusean framework in transnational contexts enhances its ability to explain migrant career experiences

Negatively modified scattering

In a paper published in 1923, Einstein and Ehrenfest discussed the general problem of thermodynamical equilibrium in an assembly traversed by light, which is subjected to scattering by the particles of the assembly. They deduced, in a way (which is quite analogous to Einstein's famous deduction of the laws of black body radiation by consideration of thermodynamical equilibrium in the presence of Bohrtype of vibrators), that the excited particles of the system would give rise to a type of modified scattering analogous to Einstein's negative absorption. Smekal pointed out in a letter to Naturwissenschaften (1923) that if light of frequency v is scattered by the particles of the assembly, then in addition to unmodified scattering of frequency v, scattered light should also consist of light of frequency v+vk, v-vk, where hvk is the energy difference between the excited state and the normal state of the scattering particles ("Handbuch der Physik," Bd. 23, pp. 93-99)

Merging and characterising phenotypic data on conventional and rare traits from dairy cattle experimental resources in three countries

peer-reviewedThis study set out to demonstrate the feasibility of merging data from different experimental resource dairy populations for joint genetic analyses. Data from four experimental herds located in three different countries (Scotland, Ireland and the Netherlands) were used for this purpose. Animals were first lactation Holstein cows that participated in ongoing or previously completed selection and feeding experiments. Data included a total of 60 058 weekly records from 1630 cows across the four herds; number of cows per herd ranged from 90 to 563. Weekly records were extracted from the individual herd databases and included seven traits: milk, fat and protein yield, milk somatic cell count, liveweight, dry matter intake and energy intake. Missing records were predicted with the use of random regression models, so that at the end there were 44 weekly records, corresponding to the typical 305-day lactation, for each cow. A total of 23 different lactation traits were derived from these records: total milk, fat and protein yield, average fat and protein percentage, average fat-to-protein ratio, total dry matter and energy intake and average dry matter intake-to-milk yield ratio in lactation weeks 1 to 44 and 1 to 15; average milk somatic cell count in lactation weeks 1 to 15 and 16 to 44; average liveweight in lactation weeks 1 to 44; and average energy balance in lactation weeks 1 to 44 and 1 to 15. Data were subsequently merged across the four herds into a single dataset, which was analysed with mixed linear models. Genetic variance and heritability estimates were greater (P,0.05) than zero for all traits except for average milk somatic cell count in weeks 16 to 44. Proportion of total phenotypic variance due to genotype-by-environment (sire-by-herd) interaction was not different (P.0.05) from zero. When estimable, the genetic correlation between herds ranged from 0.85 to 0.99. Results suggested that merging experimental herd data into a single dataset is both feasible and sensible, despite potential differences in management and recording of the animals in the four herds. Merging experimental data will increase power of detection in a genetic analysis and augment the potential reference population in genome-wide association studies, especially of difficult-to-record traits.European Commission Seventh Research Framework Program (Grant Agreement KBBE-211708, RobustMilk project); RERAD grant to Scottish Agricultural Colleg

Smooth multi-patch discretizations in Isogeometric Analysis

With the aim of a seamless integration with Computer-Aided Design, Isogeometric Analysis has been proposed by Hughes et al. (2005) as a numerical technique for the solution of partial differential equations. Indeed, isogeometric analysis is based on splines, the same functions that are adopted for geometry parametrizations in CAD. Smooth splines yield two important benefits when compared to C0 piecewise polynomial approximations: superior accuracy and stability, and the possibility to directly discretize high-order differential equations, such as the ones arising in thin-shell theory, in fracture models, in phase-field based multiphase flows, and in geometric flows on surfaces. In this chapter we review three different methods to construct C1 isogeometric spaces on multi-patch domains or unstructured quadrilateral meshes. The first, proposed in Collin et al. (2016), is based on the concept of geometric continuity, well-known in geometric design. The second, from Toshniwal et al. (2017c), uses a specific singular construction (the D-patch construction) at extraordinary points. The third is a polar construction from Toshniwal et al. (2017a). Such constructions possess properties that make them suitable for performing both computational analysis and geometric modeling
