The extension of basic schooling from six to nine years in 1968 was the largest expansion of education in Taiwan’s modern history. More than 140 new junior high schools were opened in 1968 under this program, increasing the number of junior high schools by 70 percent from 1967 to 1968. We evaluate the effect of this program on education and wages by(More)
"The purpose of this paper is to investigate the impact of locational and individual characteristics upon interstate retiree migration, particularly in state-level public policy variables. Data regarding the characteristics of individual movers are drawn from the 1990 U.S. Census of Population and Housing 5% Public Use Microdata Sample. The household data(More)
"Regional scientists remain interested in studying interregional differences in the growth rates of population and employment. Following the earlier work of Carlino and Mills, this paper examines growth trends at the county level in the U.S. during the period 1981-1989. Five major sectors of employment are examined. A partial adjustment model is developed(More)
Absorbed radiation dose in bone marrow, thyroid, salivary gland, eye, and skin entrance was determined by placement of lithium fluoride thermoluminescent dosimeters (TLD's) at selected anatomical sites within and on a human-like x-ray phantom. The phantom was exposed to radiation from linear tomographic and computer-assisted tomographic (CT) simulated(More)
OBJECTIVES The purpose of this investigation was to measure the tissue-absorbed dose and to calculate the whole-body effective dose (E) for a new generation panoramic machine (Planmeca PM 2002 CC Proline), operating in the panoramic examination mode. Comparisons could then be made with historical panoramic and intraoral radiographic dose measurement values(More)
The purpose of this study was to determine the effects of systematic changes in stride rate and length at a given running speed on the peak shank deceleration (PSD) experienced during ground contact. Data were collected from 10 well-trained subjects as they ran on a treadmill at a pace of 3.8 m s-1 (7-min mile-1). Shank deceleration was measured by a(More)
