According to Rogoff (1995), Purchasing Power Parity (PPP) fits well one empirical feature of the data, namely the high short-run volatility of real exchange rates, but also implies that shocks should die away in one to two years (the time interval compatible with price and wage stickiness). However, existing point estimates of half-life deviations from PPP(More)
Leakage from forest carbon sequestration—the amount of a program's direct carbon benefits undermined by carbon releases elsewhere—depends critically on demanders' ability to substitute non-reserved timber for timber targeted by the program. Analytic, econometric, and sector-level optimization models are combined to estimate leakage from different forest(More)

Over the last two decades, the international community has begun to conclude that attempts to ensure the territorial security of nation-states through military power have failed to improve the human condition. Despite astronomical levels of military spending, deaths due to military conflict have not declined. Moreover, even when the borders of some states(More)
—A growing literature indicates that tempera-mental emotionality traits may represent diatheses for mood disorders. This article describes the advantages of laboratory methods for assessing these traits, reviews issues regarding their use, and argues that these techniques provide unique opportunities for advancing understanding of temperamental risk.(More)
(2006) Meeting the design challenges of nano-CMOS electronics: an introduction to an upcoming EPSRC pilot project. Abstract The years of 'happy scaling' are over and the fundamental challenges that the semiconductor industry faces, at both technology and device level, will impinge deeply upon the design of future integrated circuits and systems. This paper(More)

" Diffuse correlation spectroscopy " (DCS) is a technology for non-invasive transcranial measurement of cerebral blood flow (CBF) that can be hybridized with " near-infrared spectroscopy " (NIRS). Taken together these methods hold potential for monitoring hemodynamics in stroke patients. We explore the utility of DCS and NIRS to measure effects of(More)
A recent article by Shibata et al. [1] and an interview with the senior investigator Kobayashi [2], both in the October 2006 issue of Journal of Leukocyte Biology, discuss the role of macrophage-derived NO in the clearance of apoptotic cells. We were surprised that neither in the original paper nor in the accompanying interview was it discussed that these(More)
