    Notes: Abstract The major volatile components in the extract of the female sex pheromone gland ofAmorbia cuneana consisted of (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates. The identification was based on electroantennogram bioassay of gas Chromatographic effluent from sex pheromone gland extract, relative retention times on polar and nonpolar gas chromatographic columns, chemical degradation (ozonolysis, saponification), mass spectrometry, chemical synthetic methods, and field tests. Based on mass spectrometry and retention times by capillary gas chromatography, traces of (E)-10-tetradecen-1-ol acetate and 1-tetradecanol acetate were also present in the extract. Traps baited with a combination of synthetic (E,E)- and (E,Z)-10,12-tetradecadien-1-ol acetates caught more males than did traps baited with females.

    Differences between vertical transfers and native students in four-year institutions (1977)
    Springer
    Research in higher education 7 (1977), S. 145-154

    Notes: Abstract Data from the National Longitudinal Study of the High School Class of 1972 were drawn to compare those who transfer from two-year colleges and those who enroll in four-year institutions immediately after high school. The comparisons were made on background variables, individual characteristics, and financial aid status. Results indicated that transfers came from lower SES families, and had lower academic ability, high school achievement, and educational aspiration than native students. Transfers were less likely than native students to receive scholarships, fellowships, or grants, and they showed lower achievement in the year after transfer. Implications of these findings are discussed.
