International Migration as Absolute Natural Law: An Inquiry into International Migration from the Perspective of Legal Philosophy
This paper investigates to what extent international migration law is coherent with the concept of migration as a natural human right. Based on the assumption that migration is an inherently human behavior, beneficial to humankind, and therefore natural law, an analysis of the most prominent sources of international migration law is undertaken. The result of the analysis shows that modern international migration law is largely in line with the concept of natural law, and that the criminalization of migration happens on the domestic level, where economic and populist motivations inform policy makers and shape the law
A new catalogue of Stroemgren-Crawford uvbybeta photometry
A new all-sky catalogue of all available uvbybeta measurements from the
literature was generated. The uvbybeta photometric system is widely used for
the study of various Galactic and extragalactic objects. It measures the colour
due to temperature differences, the Balmer discontinuity, and blanketing
absorption due to metals. The data for the individual stars were cross-checked
on the basis of the Tycho-2 catalogue. This catalogue includes very precise
celestial coordinates, but is magnitude and spatial resolution limited.
However, the loss of objects is only marginal and is compensated for by the
gain of homogeneity. In total, 298 639 measurements of 60 668 stars were used
to derive unweighted mean indices and their errors. Photoelectric and CCD
observations were treated in the same way. The presented data set can be used
for various applications such as new calibrations of astrophysical parameters,
the standardization of new observations, and as additional information for
ongoing and forthcoming all-sky surveys.Comment: Accepted for publication in Astronomy and Astrophysics: 3 pages, 3
