In mid-1995, a government effort to reduce the supply of methamphetamine precursors successfully disrupted the methamphetamine market and interrupted a trajectory of increasing usage. The price of methamphetamine tripled and purity declined from 90 percent to 20 percent. Simultaneously, amphetaminerelated hospital and treatment admissions dropped 50 percent and 35 percent, respectively. Methamp...

1. Age-Related Cognitive Decline (ARCD) Age related cognitive decline (ARCD) [1] is the scientific term for memory loss in elderly people who are clinically healthy. It is a physiological process associated with aging, not a disease, and occurs during middle life or later. Many people who are clinically healthy find as they get into their forties or fifties, sometimes even as early as their thi...

Hospital costs have continued to rise at rates well in excess of inflation generally, even after the introduction of Medicare's per case prospective payment system (PPS). This article uses a hospital subscriber microcost reporting system to show trends in costs, wages, labor hours, and outputs for more than 50 individual departments from 1980-92. Descriptive results show dramatic growth in the ...

The heavy-fog statistics for 256 first-order weather stations were utilized to update analyses of the geographic distribution of f o g within the conterminous United States. The survey shows that heavy fog (visibility one-fourth mile or less) occurs more than 20 days a year at approximately 50 percent of the first-order weather stations (of which 229 are air terminals) and that the mean heavy-f...

It is estimated that only approximately 20 percent of adult European Roma have attained higher than primary education. Scholars identified different potential causes the unfavourable school...

This paper examines the effect of workers' compensation on time out of work. It introduces a "natural experiment8 approach of comparing individuals injured before and after increases in the maximum weekly benefit amount. The increases examined in Kentucky and Michigan raised the benefit amount for high-earnings individuals by approximately 50 percent, while low-earnings individuals, who were ...

The characteristics of the electron-photon showers initiated by 2 to 10 GeV electrons aligned along the < 111 >-axis of tungsten crystals are compared with those for the amorphous tungsten. In this energy range, as known, the positron yield at the optimal target thicknesses is larger in a crystal case only by several percent. However, the amount of the energy deposition in a crystal turns out t...

For the purpose of the Community Guidelines, the definition of a fall is that adopted by the World Health Organisation [33]. A fall is an event which results in a person coming to rest inadvertently on the ground or floor or other lower level. This definition excludes falls resulting from an intentional change in position, but does include those where the person inadvertently comes to rest on f...
