The generic name Furia (F. submissa Egorova and Shabanov, 1987, by original designation) was proposed by Egorova and Shabanov (1987, p. 74) for a new trilobite genus from the middle Cambrian of Yakutia, Siberia. However, this name is already preoccupied by Furia Linnaeus (1758, p. 644). To resolve homonymy, in accordance with the International Code of Zoological Nomenclature, Shabanovia nom. no...

Examination of sectioned, embedded material showed that almost all intermediate filaments normally present in cultured chick embryo fibroblasts, IMR-33 cells, and BHK-21 cells were eliminated by trypsinization. At the same time atypical filaments of intermediate size were formed by close apposition of thin filaments. Previous observations (Buckley et al., 1978, J. Cell Biol. 78:644-652) on nega...

This paper studies the large concentration of retirement behavior around statutory ages, a puzzling stylized fact. To investigate this fact, I estimate bunching responses to 644 pension benefit discontinuities, using administrative data on universe German retirees. Financial incentives alone cannot explain patterns, but there is direct effect ages. argue that framing ages as reference points fo...
