Teenage Mothers as Rhetors and Rhetoric: An Analysis of Embodied Exigence and Constrained Agency
This dissertation examines the rhetorical function and social implications of the "dominant narrative of teenage pregnancy"--that is, the popular depiction of young motherhood as the tragic downfall of a woman's life. I employ feminist poststructuralist and visual rhetorical critique to analyze historical and contemporary teenage pregnancy prevention materials as well as journalistic representations of young mothers. Building from this analysis, I argue that the dominant narrative pathologizes teenage mothers, prevents a focus on structures of inequality and poverty, sustains racialized gender ideologies, and encourages practices that perpetuate disparities for pregnant/mothering young women. In addition, this project explores strategies for resisting this discourse. Specifically, I review scholarship that has contested the dominant narrative and identify counter-rhetorical practices that some young mothers use in their published first-person narratives. Finally, drawing on focus groups I conducted with 27 young mothers, I illustrate that visibly young pregnant and parenting women are often publically confronted by strangers because they embody an urgent and much-debated social issue. I offer the concept of "embodied exigence" as a way to understand how discursive and material realities of the body may construct rhetorical situations and how the body may function as a site of constrained agency. Building from rhetorical theories of agency, exigence, and feminist work on the visibility of motherhood, I assert that in moments of embodied exigence, marginalized young mothers may seize the opportunity to resist dominant rhetoric and act as rhetors in their own right

Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies
Flare frequency distributions represent a key approach to addressing one of
the largest problems in solar and stellar physics: determining the mechanism
that counter-intuitively heats coronae to temperatures that are orders of
magnitude hotter than the corresponding photospheres. It is widely accepted
that the magnetic field is responsible for the heating, but there are two
competing mechanisms that could explain it: nanoflares or Alfv\'en waves. To
date, neither can be directly observed. Nanoflares are, by definition,
extremely small, but their aggregate energy release could represent a
substantial heating mechanism, presuming they are sufficiently abundant. One
way to test this presumption is via the flare frequency distribution, which
describes how often flares of various energies occur. If the slope of the power
law fitting the flare frequency distribution is above a critical threshold,
as established in prior literature, then there should be a
sufficient abundance of nanoflares to explain coronal heating. We performed
600 case studies of solar flares, made possible by an unprecedented number
of data analysts via three semesters of an undergraduate physics laboratory
course. This allowed us to include two crucial, but nontrivial, analysis
methods: pre-flare baseline subtraction and computation of the flare energy,
which requires determining flare start and stop times. We aggregated the
results of these analyses into a statistical study to determine that . This is below the critical threshold, suggesting that Alfv\'en
waves are an important driver of coronal heating.Comment: 1,002 authors, 14 pages, 4 figures, 3 tables, published by The
