Occupational Segregation and the Tipping Phenomenon: The Contrary Case of Court Reporting in the USA

GENDER, WORK & ORGANISATION, Issue 2 2007
Joyce P. Jacobsen
The ,tipping' phenomenon, whereby an occupation switches from dominance by one demographic group to dominance by another, has occurred in various occupations. Multiple causes have been suggested for such switches, including several related to technological change, both through effects on the performance of the work and through the effect of changing demand for different occupations. The court reporting occupation provides a novel setting for testing the relevance of various proposed causes for the increased feminization of many occupations. In this case, many of the general correlates, including declining wages, are not found; rather the phenomenon is related to the earlier feminization of the clerical workforce and the increased identification of court reporting with clerical work.

Strain Rate Effects in the Mechanical Response of Polymer-Anchored Carbon Nanotube Foams,

ADVANCED MATERIALS, Issue 3 2009
Abha Misra
Strain rate effects on the mechanical properties of carbon nanotube forests are studied, and several related interesting new phenomena are reported. Dense vertically aligned foam-like forests of carbon nanotubes are anchored on a thin, flexible polymer layer to provide structural stability, particularly at the higher strain rates. Permanent deformation and for the first time the delamination and crumbling of carbon nanotube walls is observed. [source]

Some remarks on domination

JOURNAL OF GRAPH THEORY, Issue 3 2004
D. Archdeacon
Abstract We prove a conjecture of Favaron et al. that every graph of order n and minimum degree at least three has a total dominating set of size at least n/2. We also present several related results about: (1) extentions to graphs of minimum degree two, (2) examining graphs where the bound is tight, and (3) a type of bipartite domination and its relation to transversals in hypergraphs. © 2004 Wiley Periodicals, Inc.

New relations between similarity measures for vectors based on vector norms

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 2 2009
Leo Egghe
The well-known similarity measures Jaccard, Salton's cosine, Dice, and several related overlap measures for vectors are compared. While general relations are not possible to prove, we study these measures on the "trajectories" of the form , where a > 0 is a constant and ||·|| denotes the Euclidean norm of a vector. In this case, direct functional relations between these measures are proved. For Jaccard, we prove that it is a convexly increasing function of Salton's cosine measure, but always smaller than or equal to the latter, hereby explaining a curve, experimentally found by Leydesdorff. All the other measures have a linear relation with Salton's cosine, reducing even to equality, in case a = 1. Hence, for equally normed vectors (e.g., for normalized vectors) we, essentially, only have Jaccard's measure and Salton's cosine measure since all the other measures are equal to the latter.

Brahms and the Principle of Destabilised Beginnings

MUSIC ANALYSIS, Issue 1 2009
Ryan Mcclelland
ABSTRACT Despite the considerable research on moment-to-moment motivic development in Brahms's instrumental music, surprisingly few studies emphasise global thematic processes which involve transformations of initially destabilised thematic material. After placing Brahms's destabilised beginnings in the context of earlier nineteenth-century works, the article explores several pieces with destabilised beginnings in order to demonstrate Brahms's range of techniques for tonal and rhythmic-metric destabilisation, strategies used to maintain destabilisation at preliminary thematic returns and the relationships between destabilised beginnings and their eventual stabilised form. Tonal destabilisation subsumes several related and somewhat overlapping techniques, and the article pursues six which have particular relevance in Brahms's music: (1) stylistically marked chromaticism, (2) unusual dissonance treatment, (3) denial of harmonic or melodic cadence, (4) minimally stable diatonic harmonisation, (5) disjuncture between harmonic function and sonority type and (6) ambiguous establishment of key. The briefer consideration of rhythmic-metric destabilisation studies dissonance (1) at the level of metre and (2) at some level of hypermetre. The concluding section addresses stylistic and genre-specific constraints on destabilised beginnings as well as the implications of destabilised beginnings for the analysis of musical form, especially the distinction between rondo and modified sonata designs.
