This article offers a detailed analysis of a Kachchhi-Gujarati manuscript chart of the southern Red Sea and Gulf of Aden dating probably from the eighteenth or early nineteenth centuries and held at the Royal Geographical Society–Institute of British Geographers in London (mr Asia S.4.). The origins and possible dating of the manuscript are examined. Astronomical data inscribed on the chart, establishing latitude and providing sailing directions, are identified, interpreted, and projected. Its Devanagari toponyms are transcribed and identified with real-world locations. Coastal profiles and unnamed features representing significant navigational landmarks are individuated. Islamic buildings depicted on the chart are identified as specific regional mosque-shrines. The presence of Ottoman and other regional polities are inferred. The place of the chart within an early modern tradition of western-Indian navigational manuscripts and a wider Indian Ocean tradition is explored. Our analysis establishes the chart as a detailed and highly practical navigational work—countering earlier scholarly denigrations of its accuracy. In contrast, we show it to be one of the most detailed surviving indigenous navigational charts produced in an Indian Ocean tradition.

Research in prosodic phonology, as well as experiments on adult speech production, suggest that segmental and suprasegmental processes in language are not governed directly by syntactic structure. Rather these processes reflect an independent prosodic structure, which includes prosodic categories such as metrical foot, prosodic word, and phonological phrase. Five experiments examined English-speaking two-year-olds' omissions of object articles in different prosodic structures. The data indicate that children omit unfooted syllables and that foot boundaries, in turn, are influenced by prosodic word and phonological phrase boundaries. Thus, it appears that children create prosodic structures remarkably similar to those proposed in theories of prosodic phonology.

This article is a reply to Kuno et al. 1999, which claims that a structural approach to scope should be replaced by an expert system. But the alleged theoretical and empirical problems faced by the structural accounts for scope are based on assumptions or interpretations that are not adopted in the structural accounts. Further, there are problems with the characterization and execution of the expert system, causing difficulty in the understanding and application of the system intra- and interlinguistically; the expert system is not empirically adequate and does not accommodate idiolectal variations. Finally, the expert system misses important correlations between scope and other properties in the grammar, such as binding, that follow straightforwardly from a structural approach. A structural approach to scope should not be abandoned in favor of an expert system.

A database of ca. 970 radiocarbon dates on bones, teeth, and tusks of the woolly mammoth (Mammuthus primigenius Blum.) from Siberia was created in order to understand the spatiotemporal distribution of this species over the last 50,000 14C years (BP). Mammoths populated all parts of Siberia until ca. 12,000 BP. After that, a few refugia exited south of ca. 60°N at ca. 10,600–12,000 BP, and in the northern part of mainland Siberia mammoths survived until ca. 9700 BP. At ca. 9500–3700 BP, they existed only in today’s insular regions such as the New Siberian Islands and Wrangel Island in the High Arctic. The relationship between the dynamics of mammoth populations and climatic fluctuations is complicated. In the warmer intervals (interstadials), the number of mammoths in Siberia was generally slightly larger than in the colder times (stadials); however, the difference is often not significant. The connection between the dynamics of mammoth populations and climatic fluctuations in Siberia is therefore complicated and non-linear.

Although coarticulatory variation is largely systematic, and serves as useful information for listeners, such variation is nonetheless linked to sound change. This article explores the articulatory and perceptual interactions between a coarticulatory source and its effects, and how these interactions likely contribute to change. The focus is on the historical change VN (phonetically, ṼN) > Ṽ, but with more general attention to how a gesture associated with a source segment comes to be reinterpreted as distinctively, rather than coarticulatorily, associated with a nearby vowel or consonant. Two synchronic factors are hypothesized to contribute to reinterpretation: (i) articulatory covariation between the duration of the coarticulatory source (here, N) and the temporal extent of its effects (Ṽ), and (ii) perceived equivalence between source and effect. Experimental support for both hypotheses is provided. Additionally, the experimental data are linked to the historical situation by showing that the contextual conditions that trigger (i) and (ii) parallel the conditions that historically influence phonologization of vowel nasalization.
