If economic growth elsewhere raises an individual’s earning prospects relative to his present location, then the individual will move. However, if the individual can exploit economic growth elsewhere by commuting, he will not need to move to gain from the expansion. County-level data from eight states in the Midwest over the period 1969–1994 are used to show that local county population respond...

In the United States, heroin use is increasing and was implicated in 3805 deaths in 1993 (1). Multnomah County is Oregon's most populous county (1998 estimated population: 641,900); three fourths of county residents live in Portland. In 1999, in response to community concerns, the Multnomah County Health Department analyzed medical examiner (ME) data for 1993-1999 and interviewed heroin users t...

We performed variance component-based linkage analysis in four samples (two of non-Hispanic European-Americans from Rochester, MN; African-Americans from Jackson, MS; and Mexican-Americans from Starr County, TX) to identify chromosomal regions containing genes influencing plasma apolipoprotein E (apoE) levels. The APOE gene region on chromosome (chr) 19 was identified with a LOD > or = 2.00 in ...

Transmissivity results from eight aquifer tests were used to derive horizontal hydraulic conductivity values for hydrogeologic units underlying the Sequim-Dungeness Peninsula in Clallam County. Specific-capacity information for the tested production wells also was analyzed to obtain a second hydraulic conductivity value for comparison against the "aquifer test" results. These paired estimates d...
