Intersectionality, Institutions, & Inequality: STEM Majors and Status Competition Processes in the U.S. Higher Education System. 公开

Abstract

This dissertation studies the effects of the intersectionality of gender, race and class on
majoring in science, technology, engineering and math (STEM) fields within a status
competition framework. It expands research on inequality in STEM in three ways. First, I
focus representation of intersectional status groups, allowing for comparisons among men
and among women, as well as between men and women. Second, I analyze disparities
among STEM majors - comparing life science and mathematical science (physics, math,
engineering, computer science) majors. Third, I explore interactions between institutional
context and status effects. I conduct weighted logistic regression analyses on recent data
from the Beginning Postsecondary Students Longitudinal Survey (BPS:04/09) and the
Integrated Postsecondary Educational Data System (IPEDS). STEM majors are students
who have completed a bachelor's degree in or are working toward a bachelor's degree in
a STEM field in what would be their sixth year. Results confirm previous findings that
Asians and men are overrepresented in STEM, but also show significant intersectional
effects. Parental income operates differently by race; income is negatively associated
with STEM rates for whites, blacks and Asians, but positively associated with STEM
rates for Hispanics. Among women, parental education levels are positively associated
with STEM rates (no effect for me). I also find variation among STEM majors. Men are
more likely to major in math sciences than life sciences, as are black students (especially
from lower income families), lower income Asian men, and women of color (vs. white
women). Asian men are more likely to major in the life sciences than the math sciences.
Finally, I explore five institutional contexts (public, Carnegie Doctorates, land-grants,
HBCUs and Hispanic-serving institutions) and find that the salience of intersectionality
varies by context. I argue that the activation of particular intersectional statuses in certain
institutional contexts (and not in others) results from variation in status competition
processes for STEM majors. Thus, my results demonstrate the importance of considering
intersectional status in the creation of policies that seek to broaden participation in STEM
and reinforce the existence of multiple pathways into STEM instead of a single "leaky"
pipeline.
