Two factors have been proposed as the main determinants of phonological typology: channel bias, phonetically systematic errors in transmission, and analytic bias, cognitive predispositions making learners more receptive to some patterns than others. Much of typology can be explained equally well by either factor, making them hard to distinguish empirically.(More)
Mutation has typically been viewed in autosegmental frameworks as an instance of ‘object’-type morphology. The central claim of autosegmental phonology (Goldsmith 1976) is that tones, features, and length/weight (that is, moras, in the currently prevailing view) are representational entities in their own right, not simply attributes of segments. Mutation(More)
This paper explores the notion that all constraints are present in all grammars (‘Universality’). For any pair of constraints, Universality is shown to produce four types of system, differing in terms of the constraints’ activity (i.e. visible effect). Conditions on the typological predictions are identified. Building on Samek-Lodovici (1996, 1998a,b), one(More)

This paper is about the relation between contrast and ‘prominent positions’ − i.e. onsets, stressed syllables, and root-initial syllables.1 A number of works have assumed that only one of the three logically possible relations between contrast and prominent positions exists: namely that contrasts in non-prominent positions are always a subset of those in(More)
Research into the benefits that ecosystems contribute to human wellbeing has multiplied over the last few years following from the seminal contributions of the international Millennium Ecosystem Assessment. In comparison, the fact that some ecosystem goods and services undermine or harm human wellbeing has been seriously overlooked. These negative impacts(More)
Sacred sites are important not only for their traditional, spiritual or religious significance, but may also potentially be valuable for biodiversity conservation in human transformed landscapes. Yet, there has been little consideration of sacred sites in urban areas in this respect. Consequently, to better understand the ecosystem service and conservation(More)
Focusing on weight-insensitive binary stress systems, the article presents an approach to metrical stress that is more restrictive than standard approaches and more accurate in its predictions. The proposal’s restrictiveness derives from a set of constraints and structural assumptions that run counter to prevailing theories’ fundamental principles. For(More)
