The present study examines whether increment-decrement asymmetries reported in a number of recent center-surround situations occur in more complex images as well. Subjects saw the CRT simulation of a whole uniformly illuminated array of foreground surfaces presented against a large background surface and, for a number of different viewing contexts, made achromatic settings over a wide range of ...

If a Williamson matrix of order 4w exists and a special type of design, a set of Baumert-Hall units of order 4t, exists, then there exists a Hadamard matrix of order 4tw. A number of special Baumert-Hall sets of units, including an infinite class, are constructed here; these give the densest known classes of Hadamard matrices. The constructions relate to various topics such as pulse compression...

In the present paper which follows our previous paper “Mathematical models for passive imaging I: general background”, we discuss the case of surface waves in a medium which is stratified near its boundary at some scale comparable to the wave length. We discuss how the propagation of such waves is governed by effective Hamiltonians on the boundary. The results are certainly not new, but we have...

Last year saw the publication of IS0 31000:2009, a new globally accepted standard for risk management together with a new, associated vocabulary in ISO Guide 73:2009. These were developed through a consensus-driven process over four years, through seven drafts, and involving the input of hundreds of risk management professionals around the world. The new standard supports a new, simple way of t...

The role of written input in second language (L2) phonological and lexical acquisition has received increased attention in recent years. Here we investigated the influence of two factors that may moderate the influence of orthography on L2 word form learning: (i) whether the writing system is shared by the native language and the L2, and (ii) if the writing system is shared, whether the relevan...

This article is based on an appraisal of Cancer Information and Support Services in Britain supported by the UK-based charity Macmillan Cancer Relief. Commissioned in 2002, the appraisal formed part of a wider review aimed at extending knowledge about Cancer Information and Support Services. It was also designed to ensure that the Macmillan Cancer Information and Support Service Model continues...

The paper studies the possibility of propagation of torsional surface waves in an elastic layer with void pores over an elastic medium with void pores using the mechanics of the medium as derived by Cowin and Nunziato. The velocity equation has been derived and the results have been discussed. The study reveals that there may be more than one torsional surface wave fronts and one Love wave fron...

The period between the 1940s and 1960s saw the hardening of the modern synthesis in evolutionary biology. Gould and Provine argue that Wright's shifting balance theory of evolution hardened during this period. But their account does not do justice to Wright, who always regarded selection as acting together with drift. This paper presents a more adequate account of the development of Wright's sh...

Evidence suggests that people have a lower threshold for the conscious awareness of moral words. Given the potential motivational relevance of moral concerns, the authors hypothesized and found that motivational relevance of moral stimuli enhanced the detection of moral words. People who saw a CrimeStoppers advertisement in which a majority (vs. minority) of wanted murderers had been brought to...

We would like to draw your readers’ attention to an innovation information and communications technology project from the Otago region of New Zealand. The School of Nursing and School of Midwifery at Otago Polytechnic, Dunedin, New Zealand saw potential to work with an existing local organisation (OtagoNet) that was using video conferencing for high school educational purposes within the rural ...
