A core goal of Continuous Integration (CI) is to make small incremental changes to software projects. Those changes should then be integrated frequently into a mainline repository or branch. This paper presents an empirical study investigating if developers adjust their commit activity towards this goal after projects start using CI. To this end, we analyzed the commit and merge activity in 93 ...

Editor’s Note: Readers should be aware of the forum’s format. William G. Travis, Bruce A. Ware, D. A. Carson, and C. Ben Mitchell have been asked specific questions to which they have provided written responses. These writers are not responding to one another. The journal’s goal for the Forum is to provide significant thinkers’ views on topics of interest without requiring lengthy articles from...

Color adjectives have played a central role in work on language typology and variation, but there has been relatively little investigation of their meanings by researchers in formal semantics. This is surprising given the fact that color terms have been at the center of debates in the philosophy of language over foundational questions, in particular whether the idea of a compositional, truth-co...

The rate of bactericidal activity of a new quinolone, CI-934, was compared with that of amoxicillin for 20 strains of Streptococcus faecalis. At 10 and 100 micrograms/ml, the bactericidal activity of CI-934 was more rapid at 6 h than that of amoxicillin. A paradoxical effect (a killing rate higher at 1 microgram/ml than at 100 micrograms/ml at 6 h) was observed for 19 of the 20 strains with amo...
