Patterns of Blood Pressure in Milwaukee

Blood pressure measurements were obtained among 92,074 persons in Milwaukee between 1974 and 1976 by the Milwaukee Blood Pressure Program. Systolic hypertension was more prevalent in young white men than blacks below 25 years of age, was more common in middle-aged blacks than whites, and was equally prevalent among all persons past 65 years. Diastolic hypertension was more prevalent in blacks than whites of all ages. Whereas the prevalence of systolic hypertension in the population increased with age and was present in a majority or near majority of persons past 65 years, the prevalence of diastolic hypertension rose until the sixth decade, after which it declined. Hypertension was primarily of a diastolic variety in young blacks, whereas systolic hypertension was a prominent feature in young whites.

The Development of Auditory Sequential Memory in Young Black and White Children

Several studies appear to establish the occurrence of a relatively high level of auditory memory skill for preschool, kindergarten, and first grade black children, especially those from the midwest. This study is concerned with the development of this ability in black and white children in the southeast and the generalizability of the previous findings. The sample consisted of 122 black children and 120 white children in kindergarten through the third grade in two racially mixed schools in a large southern community. Scores on the Illinois Test of Psycholinguistic Abilities were subjected to a two way ANOVA. Results did not support previous findings as reported in the literature. Nor did the data support a superiority of black children in the skill tested

The Development of Racial Attitudes in Young Black and White Children

Abstract Racial attitude development was assessed in four age groups of black and white children (37 four-year-olds, 38 five-year-olds, 40 six-year-olds, and 41 seven-year-olds) through the use of a structured, open-ended interview employing black and white dolls as stimuli. The majority of statements made at each age level by both the black and the white children were meaningful, as opposed to irrelevant, and the black and white children at all age levels described both the black and white stimuli with responses that were preponderantly concrete, neutral in evaluative connotation, and nonpejorative. The method and findings of this study were contrasted with the results of racial attitude studies using forced-choice methods, and the discrepant depictions of racial attitude structure in young children found by these two methods were discussed.

Comparative Weights and Body Lengths of Parthenogenetic and Normal Turkey Embryos

INTRODUCTIONDEVELOPMENT of the germinal discs of newly laid unfertilized turkey eggs is characterized by a pronounced time lag in onset of development. The developing blastoderm of a newly laid fertilized turkey egg starts to develop soon after eggs are placed in the incubator and can be detected before the candler by 18 to 24 hours of incubation (Olsen and Marsden, 1954a). In contrast, some of the developing blastoderms of unfertilized turkey eggs first become visible at 48–72 hours, while others may require as much as 144 hours of incubation before they can be detected by candling (Olsen and Marsden 1954b; Olsen, 1965a). This present investigation was conducted to establish comparative growth curves for parthenogenetic and normal embryos.MATERIAL AND METHODSParthenogenetic embryos employed developed in unfertilized eggs of young Beltsville Small White (BSW) and heterozygous bronze (HB) turkey hens. The HB hens were essentially Beltsville Small Whites having…
