  • TestRetest Reliability of an IconCalendarBased Questionnaire Used to Assess Occupational History
    Test-Retest Reliability of an Icon/Calendar-Based Questionnaire Used to Assess Occupational History
    Engel LS ;
    Keifer MC
    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Self-reported work histories can be critical for both epidemiologic and clinical purposes. However, the complexity of some work histories, such as those of migrant farm workers, can hamper recall, resulting in inaccurate reporting. Memory aids may reduce such error. This study assesses the reliability of work histories collected using such aids in ...

    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Agriculture is the second most common employer of youth and is associated with numerous occupational hazards, but few preventive efforts to protect adolescent farmworkers have been implemented or evaluated. The largest group of adolescent farmworkers is youth who live away from their natural families and migrate, mostly from Mexico, to work in U.S. ...

    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Caregiving is both an art and a science; both knowledge and skills are necessary to improve the quality of care that professionals provide. Researchers are often limited in their assessment of skill performance due to inadequate and unrealistic measurement options. Simulation using standardized patients offers researchers an objective method to eva ...

    Aberrant activation and expression of genes is the major cause of many human diseases. Most genes are quiescent or have minimal activity in affecting physiologic processes. However, in certain pathologic conditions, these genes are abruptly turned on by a preexisting genetic switch, causing them to overexpress. The nuclear transcription factor-kB ( ...

    Atrazine, a triazine herbicide widely used in the United States, contributes to surface-water and groundwater contamination, as can deisopropylatrazine (DIA) and deethylatrazine (DEA), two of its microbial degradation products. Production of DIA and DEA by native bacteria in aquatic sediments has not been investigated thoroughly. We assessed atrazi ...

    2001/11/01 | Mining Publications
    Due to variations in the thickness of U.S. coal seams, there is great variability in the height of the roof where underground miners work. Restrictions imposed by low seam heights have important safety consequences. As the height of their workplace decreases, miners must stoop, duck walk, or crawl, and their vision, posture, and mobility become inc ...

    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Although vinyl chloride is an established cause of liver angiosarcoma, the evidence is inconclusive on whether it also causes other neoplastic and nonneoplastic chronic liver diseases as well as neoplasms in other organs. Furthermore, the shape of the dose-response relation for angiosarcoma is uncertain. We have extended for approximately 8 years t ...
