    This handbook is a compilation of methods that can be used to assay population size, demographics, and status of many species of birds occurring in a wide variety of habitats. The handbook will prove useful to field biologists, managers, and scientists anywhere in the New World from the arctic through the tropics. The methods include four types of censuses for determining population size and trends, mist-netting and nest searches to determine demographic parameters, and other methods that will be useful in operating a monitoring station, including habitat and weather observations, and suggestions for training personnel and possibilities for detailed studies. Suggestions of specific methods and data forms are included

    Evidence for the transmission of parvovirus B19 in patients with bleeding disorders treated with plasma-derived factor concentrates in the era of nucleic acid test screening: TRANSMISSION OF B19V

    Parvovirus B19 (B19V) is a small, non-enveloped virus that typically causes a benign flu-like illness that occurs most frequently in childhood. The virus is resistant to current viral inactivation steps used in the manufacture of anti-hemophilic factor concentrates and B19V transmission through these products has been documented. Since 2000, B19V nucleic acid test (NAT) screening of plasma pools has been implemented to further decrease the viral burden in these products, but no study has examined populations using these products to assess the impact of the screening on B19V transmission

    Persistence and change in the establishment: Religion, education, and gender among America\u27s elite, 1950 and 1992

    This study analyzes the extent to which the religious, educational, and gender characteristics of American leaders have changed during the post-World War II period. A systematic sample of the brief biographies in the 1950-51 and 1992-93 editions of Who\u27s Who in America is used to analyze the social characteristics of American leaders. The findings indicate that non-Protestants and graduates of non-select schools are increasingly listed in Who\u27s Who, but mainline Protestants and degree holders from the top private colleges continue to be over-represented among the nation\u27s cultural and power elites. Women have made some gains but remain under-represented among the nation\u27s leaders. The findings are discussed in the context of a modified fair shares theoretical perspective, which emphasizes that religion, education, and gender serve as status factors that influence people\u27s life chances. The analysis looks at the role of status factors in educational admissions, occupational recruitment, and career mobility
