n he nurse officer took a step back and punched the prisoner in the face while he was still sitting in the chair." These are not the words of a do gooding penal reformer or the claims of an embittered relative. They were spoken under oath from the witness box of Alloa Sheriff Court in August 1992 by Dr James MacGregor. He is a local general practitioner, who with his three colleagues has been c...

Sector-level Phillips curves are estimated in French data. There is considerable heterogeneity across sectors, with vastly different estimates of the backward looking component of inflation and the duration of nominal rigidities. A multi-sector model of inflation dynamics is calibrated on the basis of these sectoral estimates. Aggregate inflation, simulated on the basis of heterogeneous sectors...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...

Delley et al. (1) propose a new proton transfer mechanism to explain the mysterious initiation mechanism (2) of the Phillips polymerization catalyst. The authors’ mechanism invokes dormant (D) sites and active Si(OH)CrR sites, as summarized in Fig. 1. A combination of transition state theory, Delley et al.’s (1) density functional theory (DFT) results, and standard microkinetic modeling techniq...

Mononuclear Cr(III) surface sites were synthesized from grafting [Cr(OSi(O(t)Bu)3)3(tetrahydrofurano)2] on silica partially dehydroxylated at 700 °C, followed by a thermal treatment under vacuum, and characterized by infrared, ultraviolet-visible, electron paramagnetic resonance (EPR), and X-ray absorption spectroscopy (XAS). These sites are highly active in ethylene polymerization to yield pol...

the geomagnetic field for two forms of spatial orientation: (1) shoreward orientation, which utilizes only directional (‘compass’) information (Phillips, 1986a,b; Phillips and Borland, 1992a,b; Deutschlander et al., 1999a,b, 2000; Phillips et al., 2001) and (2) map-based homing orientation (‘true navigation’), which utilizes both compass and geographic position (‘map’) information (Phillips, 19...
