Aseismic crustal-strain signals prior to the 2003 Mw 6.8 Chengkung, 2006 Mw 6.1 Taitung, and 2008 Mw 5.0 Antung earthquakes with epicenters located 20, 55 and 11 km, respectively, from the Antung radon-monitoring station have been calculated using the radon anomalies recorded. Specifically,...

Radon volatilization mechanism into the gas phase was hypothesized to explain the anomalous decline in groundwater radon precursory to the 2003 M <Subscript>W</Subscript> = 6.8 Chengkung earthquake in Taiwan. We initiated the monitoring of both radon and methane in the groundwater since November 2007 at well D1 in...</subscript>

Informality is a wide-spread phenomenon across the globe. We show that firms in countries with better information sharing systems and greater financial sector outreach evade taxes to a lesser degree, an effect that is stronger for smaller firms, firms in smaller cities and towns, and firms in...

Periods of 6, 12, and 24 hr with equal amounts of flow and resting are simulated via finite difference approximations and compared with a continuously flowing system for both clogged and unclogged loamy sand.

China has sought to improve enterprise performance not through privatisation as in other transition economies, but through corporatisation as means of improving corporate governance. Actual governance practices of corporatised Chinese firms are however seriously defective, characterized by...

Alternative ways to alleviate the shortage of anesthesiologists in obstetric services have been investigated in three study stages. These were (1) a survey and detailed analysis of the existing situation in one metropolitan region of the United States, (2) the construction and validation of a...
