In this paper I argue that models share important aspects in common with literary fiction, and that therefore theories of fiction can be brought to bear on these questions. In particular, I argue that the pretence theor...

New Evidence for an N = 32 Subshell

Based on self-consistent energy density calculations, Tondeur [1] proposed N = 32 as a new magic number for neutron-rich nuclides. Following the beta decay of 52K, Huck et al. [2] assigned the 2.56 MeV state in 52 20Ca32 a spin and parity of 2+. As compared to the first excited 2+ level in 50Ca, an increase in E(21 ) was observed. Huck et al. [2] suggested the rise at N = 32 was due to the ν2p3...

Network and system management activity permanently evolves to expand its scope in term of target entities as well as management tasks to answer IT environment complexity. Consequently, management application are moving to distributed and open approaches. Likewise management information have to deal with recent issues such as heterogeneity and scaleability. This paper presents and analyses these...
