This paper reports on a heretofore undescribed pattern of voicelessness dissimilation in the Kordofanian language Moro. Voiceless obstruents become voiced when preceding another voiceless obstruent in a transvocalic (≈CVC) configuration. This pattern is robust and productive across multiple morphological contexts. The phonetic facts of voicing in Moro show it to be a difference between prevoice...

this paper provides an optimality-theoretic account of dissimilation in standard persian as well as some other accents and dialects of persian. as such, this work starts by introducing optimality theory (henceforth ot) and its basic concepts and then it investigates dissimilation in this framework. it argues for the superiority of ot over derivational approaches regarding a case in which both d...

The range of aromatic compounds that support the growth of Alcaligenes eutrophus has been determined, and the pathways used for the dissimilation of these substrates have been explored, largely by enzymatic analyses. The beta-ketoadipate pathway operates in the dissimilation of benzoate and p-hydroxybenzoate; the genetisate pathway, in the dissimilation of m-hydroxybenzoate; and the meta cleava...

A largely untested hypothesis for the bacterial dissimilation of taurine was explored in Silicibacter pomeroyi DSS-3, whose genome has been sequenced. Substrate-specific transcription of candidate genes encoding taurine uptake and dissimilation (tauABC, tpa, ald, xsc, pta) was found, which corresponded to the induction of Tpa, Ald, Xsc and Pta, that was observed.

Previous studies of grapes and tomatoes have shown that the abundance of phosphoenolpyruvate carboxykinase (PEPCK) increases in their flesh at the start of ripening, and that this coincides with a decrease in its citrate and/or malate content. Thus, PEPCK might function in the catabolism of organic acid anions during the ripening of these fruits. In the present study, the abundance of PEPCK was...

In speech, the phenomenon of coarticulation (differentiation of phoneme production depending on the preceding or following phonemes) suggests an organization of movement sequences that is not strictly serial. In the skeletal motor system, however, evidence for comparable fluency has been lacking. Thus the present study was designed to quantify coarticulation in the hand movement sequences of si...

Kim, Hyung-Soo. 2003. A new look at partial reduplication in Korean. Studies in Phonetics, Phonology and Morphology 0.0. 00-000. An approach based on the phonological process of dissimilation turns out to do a better job of explaining the so-called asymmetry and delaryngealization in partial reduplication of ideophonic words in Korean than any of previous constraint-based analyses, including th...

Dissimilation is a process by which one segment systematically avoids taking on a feature (or a set of features) of a neighboring segment. In Tashlhiyt Berber, for example, labial prefixes like the reflexive [m-] delabialize when they combine with a root that also contains a primary labial consonant, i.e., [b, f, m], producing the following alternations: [n-fara] ‘disentangle’, [n-kaddab] ‘cons...
