Temporal variation in facilitator and client behavior during group motivational interviewing sessions.

There is considerable evidence for motivational interviewing (MI) in changing problematic behaviors. Research on the causal chain for MI suggests influence of facilitator speech on client speech. This association has been examined using macro (session-level) and micro (utterance-level) measures; however, effects across sessions have largely been unexplored, particularly with groups.

The nucleotide sequence of the luxA and luxB genes of Xenorhabdus luminescens HM and a comparison of the amino acid sequences of luciferases from four species of bioluminescent bacteria.

The luxA and luxB genes of bioluminescent bacteria encode the alpha and beta subunits of luciferase, respectively. Sequences of the luxA and luxB genes of Xenorhabdus luminescens, the only terrestrial bioluminescent bacterium known, were determined and the amino acid sequence of luciferase deduced. The alpha subunit was found to contain 360 amino acids and has a calculated molecular weight of 41,005 Da, while the beta subunit contains 327 amino acids and has a calculated molecular weight of 37,684 Da.
