STEM领域，也被称为科学，技术，工程和数学领域，近年来已成为多项研究和资助计划的重点。尽管做出了这些努力，但对于谁进入、谁被保留以及谁完成了STEM领域的博士学位，人们仍然存在挥之不去的担忧。这项研究利用离散时间事件历史分析，在一个研究广泛的机构，位于南方，在20年的时间内，在56个STEM部门，为10，088人建立博士流失模型。结果表明，第一年的流失率最高。此外，女性，亚洲人和那些属于硬应用科学专业（与硬纯专业相比）的人的自然减员几率更大。对于已婚学生和那些在同一项目中相对GRE分数高于同龄人的学生来说，自然减员的几率较低。本研究的结果提供了一个更深入的了解博士生的特定特征和项目之间的关系，随着时间的推移的流失率。
The STEM fields, otherwise known as the Sciences, Technology, Engineering, and Mathematics areas, have become the focus of multiple studies and funding initiatives in recent years. Despite these efforts, lingering concerns exist about who enters, who is retained, and who completes the doctorate in STEM fields. This study utilizes discrete-time event history analysis to model doctoral attrition for 10,088 individuals, in 56 STEM departments, at one research-extensive institution, located in the South, over a 20-year period. Results show that the odds of attrition are the greatest in the first year. Additionally, the odds of attrition are greater for females, Asians, and for those who belong to a hard-applied science major (versus a hard-pure major). The odds of attrition are lower for married students and for those who have higher relative GRE scores than their peers in the same program. The findings of this study provide a deeper understanding of the relationship between particular characteristics of doctoral students and programs on attrition rates over time.
