Improving Productivity by Dose Equivalency Modeling

由于毒品和酒精导致的健康状况不佳， 最近的灾难（石油泄漏，地铁事故）。 生物测定（ 体液、剪下的毛发等）可以确定 某些化学物质是在 事故，但回避的问题是，是否性能本身 被降级了 基于绩效的评估方法将允许 更直接的证据表明，在工作场所， 一旦实施，可望提高生产力。 由于测试不是实际的工作，因此需要一种索引方法 提供与工作相关的背景或标准的变更 自己 第一阶段证明了使用 酒精剂量作为指标标准和多元剂量- 创建了等效方程，以允许“拨入” 一套酒精当量水平，使组合 满足该水平的性能损失可以被“标记”。“还有， 在现场设置的灵敏度显示使用商业 航空公司飞行员在几个跨洋航班涉及多个 时区的变化，并开发了一种算法来“调整” （最小化）假阳性错误。 第二阶段的计划是 建立进一步的工作相关性和改进的敏感性（即， 命中率）以及最小化假阳性。

Lack of fitness due to drugs and alcohol has been implicated in recent calamities (oil spills, subway crashes). Bioassays (of body fluids, hair clippings, etc.) can establish whether or not certain chemicals were ingested at some point in time prior to the accident, but beg the question of whether performance itself was degraded. A performance-based assessment method would permit more direct evidence of fitness potential in the workplace and, once instituted, could be expected to improve productivity. Since tests are not actual jobs, a method is need for indexing change which provides a context or standard tied to the jobs themselves. Phase I demonstrated the feasibility of using alcohol dosage as an indexing standard and multivariate dose- equivalency equations were created to permit the "dialing in" of a set alcohol equivalency level, so that combinations of performance loss which met that level could be "flagged." Also, sensitivity in a field setting was shown using a commercial airline pilot on several transoceanic flights involving multiple time-zone changes, and an algorithm was developed to "tune" (minimize) false positive errors. Plans for Phase II are to establish further job relevancy and improved sensitivity (i.e., hit ratio) of the tests as well as minimizing false positives.
