L S Williams 《CMAJ》1995,153(11):1633-1635
Many Canadian medical families have been approached by US headhunters anxious to recruit family physicians to practise in the US. Lynne Sears Williams and her husband, Calgary family physician Jim Williams, went to Texas to see what opportunities awaited. In this article she describes the high and low points of recruitment efforts south of the border.  相似文献

Abstract

Archeological Site 48SH312 occurs upon slightly weathered shale in the uppermost portion ot the Fort Union Formation (Paleocene) of eastern Sheridan County, Wyoming. Only a trace of a paleosol is developed on the shale. Colluvium overlies the shale. The site is a small remnant of a ravine floor which existed during Kaycee time. Physiography of the present ravine and local distribution of resistant lenticular strata in the Fort Union Formation, suggest that the paleo-ravine was a box ravine with near vertical walls of 5-10 meters. Paleosol development, weathering features, and homogeneity of colluvium are interpreted as indicating a surface that represents late Kaycee time and provides a geological age for the site of 3500 to 4000 years before present.  相似文献

Dendrochronology, the science of tree‐ring dating, is the most accurate and precise nondocumentary dating method available to researchers studying the recent past. Tree‐ring dates are accurate and precise to the year and sometimes the season, and have no associated statistical uncertainty or standard error. Other prominent archeological dating techniques that use natural materials (for example, radiocarbon and archeomagnetism) have been calibrated using dendrochronological samples. 1 It is this precision and accuracy that has allowed archeologists working in the southwestern United States to construct the most detailed chronologies in the world, and to explore a plethora of environmental, social, and behavioral questions regarding past human adaptation to the region.  相似文献
