Gradient dissimilation in Mongolian: implications for diachrony

Modelling diachrony in dictionaries

Introduction : The variety of lexical structures Lexical data appear in a wide variety of forms. These can range from basic morpho-syntactic structures (Romary et al., 2004) intended to be used in language engineering application to important editorial projects that cover multiple levels of lexicographic description: morphological information, syntactic constructs, sense related information (de...

Morphological Universals and Diachrony

Although linguistics is plausibly taken to be “the science of language,” the actual object of inquiry in the field has changed considerably over time. Prior to the influence of deSaussure in the first part of the twentieth century, linguists concerned themselves primarily with the ways in which languages have developed historically. For the next several decades, they devoted their attention to ...

Diachrony of mammalian appearance events : Implications for biochronology : Comments and Reply

Alroy (1998) argued that there is significant diachrony in the first and last appearance events (FAE and LAE) of Cenozoic mammals in North America, and therefore individual events cannot be used for biochronology. A close examination of the data used in his paper, however, suggests that (1) most of the diachrony is largely a sampling artifact, and (2) once sampling is factored out, the remainin...

Methanol dissimilation in Desulfotomaculum kuznetsovii

The enzymes involved in methanol degradation by Desulfotomaculum kuznetsovii, a thermophilic, methanol utilizing sulfate reducer were studied. Low NAD-dependent and dye-linked alcohol dehydrogenase activities were detected with methanol in cell free extracts of D. kuznetsovii grown on methanol. However, activities with ethanol as electron donor were 10 times higher. The alcohol dehydrogenase fr...
