    Receiver Operating Characteristic (ROC) and Reproducibility Analyses of FDA-Cleared Latex-Specific IgE Assays
    Biagini, Raymond E. ;
    Hamilton R
    2000/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    The diagnostic performance of FDA-cleared latex specific IgE immunoassays has been reported using manufacturers' derived cutoffs (JACI, 103:925-930, 1999). We extend these findings using receiver operating characteristic (ROC) curves and evaluate the repeatability of the assays at low specific IgE concentrations for latex and other antigens. Sera f ...

    A Model Of The Judgment And Decision-Making Process In Mine Fires; Behavioral And Organizational Dimensions Of Underground Mine Fires
    1/1/2000 | National Institute for Occupational Safety and Health (NIOSH)
    Various aspects of judgment and decision-making are key themes in this book. The model presented here serves as a loose structure for the chapters that follow this one. The notion of a model is introduced because growing research interest in the subjective aspects of group and individual behavior has led to a debate over whether judgment is a skill ...

    Goldberg M
    2000/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    Elevated disease rates have been documented among construction workers for cancer, pneumoconiosis, asbestosis, and silicosis. However, methodologies for exposure assessment in construction are not well described in the U.S. literature. Working through a cooperative agreement with the National Institute for Occupational Safety and Health (NIOSH), th ...

    2000/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    An area identified as having a high priority by the National Research Council (NRC 1998) relating to health effects of exposure to urban particulate matter is the investigation of particle deposition patterns in potentially-susceptible subpopulations. A key task for risk assessment is development and refinement of mathematical models that predict l ...

    Efforts are under way to develop a phenotypic analysis assay capable of identifying and differentiating chemicals with the potential to induce irritation and IgE-mediated and T-cell-mediated sensitization. These studies compare results obtained with the irritancy/phenotypic analysis assay to those obtained in the mouse ear-swelling test (MEST) and ...

    2000/01/01 | National Institute for Occupational Safety and Health (NIOSH)
    A new technique for classifying fibers according to length has opened up opportunities for improving fiber measurement technology. The classification principle is dielectrophoresis, which moves conductive fibers at a velocity proportional to the square of their length. Even non-conductive fibers can be made sufficiently conductive by increasing the ...
