OBJECTIVE To determine the duration of delays in treatment initiation when involuntary patients apply for a review of a finding of treatment incapacity and to estimate the cost of keeping patients hospitalized without treatment in these circumstances. METHOD Using a computerized database and written records, we identified all patients at 2 psychiatric(More)
The Supreme Court of Canada's (SCC) first case involving capacity and the refusal of involuntary psychiatric treatment involved a self described "professor" who had been referred to as "Canada's Beautiful Mind". He had been found not criminally responsible on account of mental disorder for uttering death threats. While considered incapable of making a(More)
Fig. 1: An overview of the VisIRR system. Given about half a million academic papers in the system, the user can start by issuing a query (A), e.g., a keyword 'disease.' By performing clustering and dimension reduction, VisIRR visualizes the retrieved documents in a scatter plot and a table view (B) along with a topic cluster summary (B)(E). In the scatter(More)
In vitro bioaccessibility (IVBA) studies were carried out on samples of mercury (Hg) mine-waste calcine (roasted Hg ore) by leaching with simulated human body fluids. The objective was to estimate potential human exposure to Hg due to inhalation of airborne calcine particulates and hand-to-mouth ingestion of Hg-bearing calcines. Mine waste calcines(More)
The isotopic composition of mercury (Hg) was determined in cinnabar ore, mine-waste calcine (retorted ore), and leachates obtained from water leaching experiments of calcine from two large Hg mining districts in the U.S. This study is the first to report significant mass-dependent Hg isotopic fractionation between cinnabar ore and resultant calcine.

Samples of soil, water, mine waste leachates, soil gas, and air were collected from areas mined for mercury (Hg) and baseline sites in the Big Bend area, Texas, to evaluate potential Hg contamination in the region. Soil samples collected within 300 m of an inactive Hg mine contained elevated Hg concentrations (3.8-11 µg/g), which were considerably higher(More)
