This paper uses data from the 1980 and 1990 U.S. Censuses to analyze the labor market experience of high-skilled immigrants relative to high-skilled natives. Immigrants are found to be more likely to be working in one of the high-skilled occupations than natives, but the gap between the two groups decreased in the 1980’s. Given the high selfemployment rates of this group of workers, about 20 pe...

Although percentage rates of alcohol consumption are higher in non-Hispanic Whites, American Indians/Alaska Natives ...

Ecosystem managers face a difficult decision when managing invasive species. If they use aggressive practices to reduce invader abundances, they will likely reduce invaders' competitive impacts on natives. But it is often difficult or impossible to reduce invaders without damaging natives. So a critical question becomes: Which is worse for native biota, invaders or things done to control invade...

INTRODUCTION Blood pressure is significantly improved with weight loss. Behavioral interventions for weight loss seem to be less successful in African immigrants. Our main aims were to assess the effect of a dietary and lifestyle intervention on weight among hypertensive Portuguese natives and immigrants and to identify success factors for weight loss, and also to evaluate changes in knowledge ...

There can at any rate be no doubt that these terms are extensively used to denote many anomalous obscure febrile conditions, which offer difficulties in diagnosis, and that in most of such cases no attempt is made to solve the problem by means of any microscopical or bacteriological examination. Further it cannot but, be admitt...
