Recent analyses of transaction-level data sets have generated new stylized facts on price setting and greatly in‡uenced the empirical openand closed-economy macroeconomics literatures. This work has uncovered marked heterogeneity in price stickiness, demonstrated that even non-zero price changes do not fully "pass through" exchange rate shocks, and o¤ered evidence of synchronization in the timi...

A limited number of evolutionarily conserved signal transduction pathways are repeatedly reused during development to regulate a wide range of processes. Here we describe a new negative regulator of JAK/STAT signaling and identify a potential mechanism by which the pleiotropy of responses resulting from pathway activation is generated in vivo. As part of a genetic interaction screen, we have id...

Andrew Donald Booth (1918-2009) was the leader of a team of computer pioneers at Birkbeck College in the University of London, UK. Booth worked with limited resources, both human and financial, and concentrated on building smaller machines. This paper presents an outline of his career in the UK which, the author believes, has not received the attention it deserves in comparison to a number of h...

Ken Wilson’s life-time achievements in fundamental theoretical physics are well known and are well documented in this memorial volume. Therefore, there is no purpose in my adding yet another appreciation of his seminal work. Rather, I shall describe Ken and some of his activities at the beginning of his career, when he was junior faculty at Cornell and I was his student — one of two in the firs...

Ken Thompson recently communicated some results mined from his set of 64 6-man endgame tables. These list some positions of interest, namely, mutual zugzwangs and those of maximum depth. The results have been analysed by the authors and found to be identical or compatible with the available or published findings of Karrer, Nalimov, Stiller and Wirth.

Many of the relationships described in this special issue, put together to honour work Ken Plummer, focus on Essex connections, intergenerational friendships, or particular intellectual concerns such as symbolic interactionism citizenship.

OBJECTIVE Accessibility of audiometry is hindered by the cost of sound booths and shortage of hearing health personnel. This study investigated the validity of an automated mobile diagnostic audiometer with increased attenuation and real-time noise monitoring for clinical testing outside a sound booth. DESIGN Attenuation characteristics and reference ambient noise levels for the computer-base...

PURPOSE To evaluate a customized, portable Farnsworth-Munsell 100 (FM 100) hue viewing booth for compliance with colour vision testing standards and to compare it with room illumination in subjects with normal colour vision (trichromats), subjects with acquired colour vision defects (secondary to diabetes mellitus), and subjects with congenital colour vision defects (dichromats). METHODS Disc...
