ABSTRACT

"The annual growth rates of total personal income and population in regional metropolitan and nonmetropolitan areas [of the United States] are examined for the period 1959-87, partitioned into sub periods. Statistical testing for equality of rates shows no perceptible differences in growth rates between the major categories, metro and nonmetro. Further, this study uses a model similar in scope to shift-share analysis to test for convergence of the growth rates within these categories. It was found that for both regional nonmetro and metro areas, there was a general trend toward convergence with the exception of the 1970s decade. In that decade total population growth rates in the nonmetro areas and total income and total population growth rates in the metro areas showed significant divergences."

ABSTRACT

Es el objetivo de este trabajo el comportamiento de los valores de glucosa durante la segunda mitad del embarazo en un grupo de gestantes sin patología evidente, que no desarrollaran diabetes gestacional y que se dividen para su análisis de acuerdo a indicadores de riesgo. Se evaluaron 29 mujeres en 4 ocasiones, 3 durante la gestación (semana 23, 30 y 36 + - 7 días) y 1 en el post-parto (50 + - 14 días). Se dividió a la población en: alto riesgo (AR) a mujeres que presentaron antecedentes familiares de diabetes mellitus en padre y/o madre positivos, y/o porcentaje de peso para la talla pregestacional (%P/T pregest.) igual o mayor a 127; mientras que se asignó bajo riesgo (BR) a las mujeres con ausencia de los indicadores antes mencionados y cuya edad fuera menor a los 31 años y el número de gestaciones menos abortos menor a 4. Se determinó glucosa en suero mediante glucosa oxidasa tanto al ayuno como en el post-prandio de 2 hrs., después de la ingesta de una carga de 100 g de glucosa. La compración entre ambos grupos de riesgo se evaluó con estadística paramétrica. El comportamiento del ayuno en ambos grupos no presenta diferentes de BR se observa a las 2 hrs., un comportamiento igualmente uniforme con una mínima variabilidad hasta el post-parto. Situación que no se presenta con las mujeres de AR cuyos valores de glucosa son significativamente mayores que los del BR y además se incrementan conforme la gestación avanza hasta en un 34%, obteniéndose una diferencia significativa entre las semanas 30 a 36 (p menor a 0.05). De los indicadores de riesgo, el % P/T pregest y la edad, fueron los indicadores con mayor grado de asociación con altos valores de glucosa.

ABSTRACT

"This note investigates regional population growth in the U.S. for 1959-84, taking into account four city sizes and three time periods. It is found that the growth is largest in city size (0.5-1.0) million and (1.0-2.0) million. Over time, the growth is largest in the less urbanized regions." The note aims to supplement the findings of Daniel Garnick and is based on data from the U.S. Bureau of Economic Analysis.

ABSTRACT

Two Jewish Ashkenazi male sibs are reported as having a new syndrome consisting of a white forelock, distinct facial features associated with congenital malformations involving the eye, cardio-pulmonary and skeletal systems. It is postulated that the etiology of this disorder is genetic and transmitted either as an autosomal recessive or X-linked recessive conditions.
