On the intonational features of yes/no interrogatives in English and Montenegrin

This paper outlines the results of an analysis of syntactically marked yes/no interrogatives in American English and Montenegrin from the persepctive of intonation. The analysis, based on the theoretical framework of Autosegmental-Metrical Phonology and the use of the computer software package Praat, treats issues regarding the different types of pitch contours and boundary tones at the end of yes/no interrogatives, gathered from various American and Montenegrin TV talk shows. Particularly, it focuses on specific intonational constituents, which indicate and clarify the alternative meanings of these questions. Having in mind the very nature of TV talk shows, which are seen as a part of a semi-institutionalized discourse, we start from the assumption that one type of intonation contour will be the prevailing one in yes/no interrogatives in both languages. Furthermore, all melodic deviations within these structures will influence and modify their basic meaning. The findings partially confirm our hypothesis, indicating a difference in the terminal contour between the two languages.

The Soddy spheres of a 4-ball tetrahedron: Part 1

New discoveries about the Soddy circles of a triangle were published in the Gazette [1] in 1995; they are summarised below. Extensions of wellknown results in the geometry of the triangle to that of the tetrahedron were presented by Zeeman in his 2004 Presidential Address at the Mathematical Association Conference in York [2]. Using the computer software package Cabri 3D, we have discovered new results which extend the Soddy circles of a triangle to Soddy spheres of a special class of tetrahedra. This article is the first of two which present our discoveries, as well as relevant aspects of the established geometry of tetrahedra, together with their proofs.
