Examines research on the frontiers of science which may lead to maximizing crop yields in response to increasing world demands for food and natural fibers. (JR)

Urban and rural school girls were randomly assigned to black and white examiners to be tested on an individually administered intelligence test. The interaction of race of examiner, race of subject, and location of subject's home on test performance was investigated. This interaction was not significant. (Author)

This research attempted to expand Piaget's study of children's thinking to include the content and the development of their concepts of death and the impact of experience on those concepts. One hundred twenty-two, middle-class, native-born boys and girls, aged three through twelve years were interviewed. Concepts were found to be composed of nine…

This study assumes that all suicidal and self-destructive behavior can be placed on a continuum from hopeful (H) to hopeless (S). The author attempts to show that there is an underlying continuum of hope corresponding to what we know about the statistics of suicidal behavior. He employs two operational hypotheses as tests of his ideas: (1) a group…

While research usually emphasizes the decrements of older persons, increases in human relations skills may be among the observable gains of aging. The present study, conducted in the Counseling Center of the Andrus Gerontology Center, evaluates the potential of using older volunteers as peer counselors. Subjects were 11 persons from a larger pool…

The case records of 348 homebound clients receiving vocational rehabilitation services from the New York State Homebound Rehabilitation Program were examined to explore attributes of homebound applicants, their rehabilitation experiences, and program outcomes. Data was summarized for characteristics which included age, most common major…

Many academic examinations exhibit sex differences in terms of entry figures and pass rates. This fact is illustrated by a selection of statistics from the British GCE "O" level examination results for June 1976. These results are discussed in terms of three possible causes: innate differences in intellectual functioning, sex role…

This document summarizes a comprehensive planning effort for the Baltimore area aimed at developing a constructive new approach for dealing with a major manpower and community problem: the situation of young high school dropouts. The program is predicated on the hypotheses that: (1) dropouts do not routinely receive counseling and referral…

In order to appropriately interpret norm referenced measures, we need to know the characteristics of persons in the standardization sample. Mercer (1977) states that evidence from three sources should be examined when deciding if pluralistic norms are needed. First, do racial-ethnic groups differ on important social, economic, and cultural…

Student withdrawals were compared to course completers in two variants of a contingency-managed lecture (CML) course and a personalized instruction (PI) course. Within both CML sections, withdrawals performed 10-25% worse on unit quizzes and 20-30% worse on review exams than did peers who completed the course. Within PI, withdrawals had a retake…

Researchers often claim validity for student ratings after finding a positive ratings/achievement correlation. This allegedly shows that ratings identify teachers who promote learning. But if students are not randomly assigned to classes, or if the correlation is not computed across classmeans, the correlation may result instead from a student…

In response to Maccoby and Jacklin's (1974) conclusion that sex differences in aggression must be biological in origin, we suggest alternative social-learning mechanisms to explain the differences. These mechanisms include: (1) punishment for aggression increases aggression in boys, particularly because boys do not identify with the punisher; (2)…

The purposes of this study were to: (1) determine the feasibility of increasing the quality of job performances of counselors and identifying changes in career maturity attitudes of counselors in the area of personnel needs of business and industry; (2) examine the effects of a structured inservice program to aid counselors in performing job…

The subjects of this study were mothers of 8-year-old and 14-year-old boys. Each mother was presented with six vignettes, four of them depicting moderately severe problem behaviors and two of them more severe problems. Mothers rated each on: (1) how serious a problem it was; (2) what might have caused it; (3) how they would attempt to deal with…

Two studies used a structural equation model to examine the relationship between gender and participation in college mathematics, physics, and chemistry courses. The intervening variables under scrutiny were ability scores, attitudes toward mathematics and mathematicians, and expectations of future performance in physical science courses. The…
