    Notes: Abstract This paper provides a comprehensive account of the regulations governing the systems of unemployment support and social assistance in post-communist Poland. To provide a solid foundation for a further discussion of these issues, the paper extensively characterizes the Polish labor force in terms of the prevalence and duration of unemployment. A final aspect of our empirical analysis concerned the question of what are the main sources of personal income for labor force participants, unemployed workers and long-term unemployed workers. In conclusion, we argue for a reform of the Polish systems of income support that separates the objectives of employment growth and poverty alleviation, and that improves upon the implementation of support schemes.

    Keywords: phylogeny ; acanthocephala ; rotifera ; bilateria ; evolution ; 18S rRNA gene
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Advances in morphological and molecular studies of metazoan evolution have led to a better understanding of the relationships among Rotifera (Monogononta, Bdelloidea, Seisonidea) and Acanthocephala, and their relationships to other bilateral animals. The most accepted morphological analysis places Acanthocephala as a sister group to Rotifera, although other studies have placed Acanthocephala as a sister taxon to Bdellodea or Seisonidea. Molecular analyses using nuclear 18S rRNA and mitochondrial 16S rRNA genes support Acanthocephala as a sister taxon to Bdelloidea, although no molecular data is available for Seisonidea. Combining molecular and morphological analyses of Bilateria leads to a tree with Platyhelminthes, Rotifera, Acanthocephala and Gnathostomulida (and probably Gastrotricha) as a sister group to the annelid-mollusc lineage of the Spiralia (Lophotrochozoa).
