Mathematical Sciences: Industry-Based Graduate Research Assistantships

9508725 Wierman数学科学中的大学-产业合作研究项目是旨在为学术界和产业界在其职业生涯的不同阶段交流数学科学家的机制而设计的项目。这些计划将加强产业界和学术界之间的联系，并确定和鼓励数学科学研究的新途径。以大学为基础的研究生研究助学金为研究生提供了部分时间在课堂上，部分时间在工业环境中的机会。这些奖项是为国家科学努力的未来活力做出贡献的一种手段。吸烟与健康办公室(OSH)、疾病控制和预防中心(CDC)的一个重要职能是估计每年死于吸烟的人数，或吸烟可归因性死亡率(SAM)。SAM是与吸烟相关的归因分数(AF)和总死亡人数的函数。归因分数反过来又是与吸烟和吸烟流行率相关的相对风险(RR)的函数。估算SAM的相关方法学问题之一是如何根据年龄、性别、种族、职业等混杂因素适当调整SAM。当使用两个独立的数据来源估算SAM时，尚不存在调整SAM的方法。这项研究的一个方面是研究一种基于准似然估计的方法。另一个研究领域将是研究接触丙烯腈与特定原因死亡率之间的关系，特别是肺癌、脑癌、前列腺癌和胃癌。

9508725 Wierman The University-Industry Cooperative Research Programs in the Mathematical Sciences are programs designed to establish a mechanism for exchange of mathematical scientists between academia and industry at different stages of their careers. These programs will strengthen the links between industry and academia and identify and encourage new avenues of research in the mathematical sciences. The University-Based Graduate Research Assistantships provide the opportunity for graduate students to spend part of their time in the classroom and part of their time in an industrial setting. These awards are a means of contributing to the future vitality of the scientific effort of the nation. One important function of the Office on Smoking and Health (OSH), Centers for Disease Control and Prevention (CDC), is to estimate the number of people who die each year from smoking, or smoking attributable mortality (SAM). SAM is a function of the attributable fraction (AF) associated with smoking and the total number of deaths. The attributable fraction, in turn, is a function of the relative risk (RR) associated with smoking and smoking prevalence. One of the relevant methodological issues in estimating SAM is how to properly adjust the SAM for confounding factors such as age, sex, race, occupation, etc. Methodology does not yet exist for adjusting the SAM when the SAM is estimated using two independent data sources. One aspect of this research is to study a quasi-likelihood based method of estimation. Another area of research will be a study of the relationship between exposure to acrylontrile and cause-specific mortality, particularly cancers of the lung, brain, prostate and stomach.
