A number of studies show that premarital cohabitation is associated with an increased risk of subsequent marital dissolution. Some argue that this is a consequence of selection effects and that once these are controlled for premarital cohabitation has no effect on dissolution. We examine the effect of premarital cohabitation on subsequent marital dissolution by using rich retrospective life-his...

The Broadcasting Automata model draws inspiration from a variety of sources such as Ad-Hoc radio networks, cellular automata, neighbourhood sequences and nature, employing many of the same pattern forming methods that can be seen in the superposition of waves and resonance. Algorithms for broadcasting automata model are in the same vain as those encountered in distributed algorithms using a sim...
Scanning tunneling microscopy has been used to study the formation of a Bi monolayer deposited on the fivefold surface of i-Al70Pd21Mn9. Upon deposition of low submonolayer coverages, the nucleation of pentagonal clusters of Bi adatoms of edge length 4.9 Å is observed. The clusters have a common orientation leading to a film with fivefold symmetry. By inspection of images where both the underly...

A mother and daughter are described with premature menopause and deletion of the X chromosome at q28. Structural anomalies of the X chromosome and ovarian failure are well known.' Secondary amenorrhoea, recognised as premature menopause and involving an X chromosomal deletion, has only been described on two occasions, the breakpoints being at q252 and q26.3 We describe familial inheritance of a...
Human serum paraoxonase (HuPON1) is a calcium-dependent enzyme that hydrolyzes esters, including organophosphates and lactones, and exhibits anti-atherogenic properties. A few amino acids have been shown to be essential for the enzyme's arylesterase and organophosphatase activities. Until very recently, a three-dimensional model was not available for HuPON1, so functional roles have not been as...

A full four-body implementation of the propagating exterior complex scaling (PECS) method [J. Phys. B 37, L69 (2004)] is developed and applied to the electron-impact of helium in an S-wave model. Time-independent solutions to the Schrödinger equation are found numerically in coordinate space over a wide range of energies and used to evaluate total and differential cross sections for a complete ...
This paper reviews a series of public sector applications of the Super Profiles geodemographic typology that was produced using data derived from the 1991 Census. The applications, often in combination with the use of GIS software, have emerged in work undertaken by the staff of the Urban Research and Policy Evaluation Regional Research Laboratory (URPERRL). Examples of applications are drawn f...
