In recent years, the debate on the problem of causal exclusion has seen an ‘interventionist turn’. Numerous non-reductive physicalists (e.g. Shapiro and Sober 2007) have argued that Woodward’s (2003) interventionist theory of causation provides a means to empirically establish the existence of nonreducible mental-to-physical causation. By contrast, Baumgartner (2010) has presented an interventi...

This paper proposes the t-class of SOBER stream ciphers: t8, t16 and t32. t8, t16 and t32 offer 64-, 128and 256-bit key strength respectively. The t-class ciphers are based on the same principles as the original SOBER family: SOBER [17], SOBER-II [18], S16 and S32 [19], utilising the structure SOBER-II and S16 are based. The t-class ciphers are software stream ciphers designed for software impl...

Two ways of mounting distinguishing attacks on two similar stream ciphers, SOBER-t16 and SOBER-t32, are proposed. It results in distinguishing attacks faster than exhaustive key search on full SOBERt16 and on SOBER-t32 without stuttering.

Sober-t32 is a candidate stream cipher in the NESSIE competition. Some new attacks are presented in this paper. A Guess and Determine attack is mounted against Sober-t32 without the decimation of the key stream by the so-called stuttering phase. Also, two distinguishing attacks are mounted against full Sober-t32. These attacks are not practically feasible, but they are theoretically more effici...

William Roche and Elliott Sober argue that explanatoriness is evidentially irrelevant. This conclusion is surprising since it conflicts with a plausible assumption—the fact that a hypothesis best explains a given set of data is evidence that the hypothesis is true. We argue that Roche and Sober?s screening-off argument fails to account for a key aspect of evidential strength: the weight of a bo...
