This chapter highlights the role of Title IX of the Education Amendments Act of 1972 and the U.S. Constitution’s Equal Protection Clause of the Fourteenth Amendment in transforming the gendered landscape of U.S. education. After first providing an overview of these two sources of law, the chapter examines the role they have played in challenging sex-based designations in admissions and in the classroom, in promoting equal opportunity and access to school-sponsored athletics, in challenging sexual harassment and other sexual misconduct, in reducing barriers to LGBT students, and in promoting equal opportunity for students who are pregnant. Sections addressing each one of these topics will also note limitations and shortcomings of the law’s approach to these issues, as there is still more work to do to fully realize sex equality in education. While the law has not cured all the problems of sex discrimination education, owing to limitations in its scope, as well as enforceability, it has proven to be a powerful source of societal norms and expectations, which themselves operate to motivate compliance and beyond.

Abstract This study documents the formation and evolution of secondary vortices associated within a large, violent tornado in Oklahoma based on data from a close-range, mobile, polarimetric, rapid-scan, X-band Doppler radar. Secondary vortices were tracked relative to the parent circulation using data collected every 2 s. It was found that most long-lived vortices (those that could be tracked for ≥15 s) formed within the radius of maximum wind (RMW), mainly in the left-rear quadrant (with respect to parent tornado motion), passing around the center of the parent tornado and dissipating closer to the center in the right-forward and left-forward quadrants. Some secondary vortices persisted for at least 1 min. When a Burgers–Rott vortex is fit to the Doppler radar data, and the vortex is assumed to be axisymmetric, the secondary vortices propagated slowly against the mean azimuthal flow; if the vortex is not assumed to be axisymmetric as a result of a strong rear-flank gust front on one side of it, then the secondary vortices moved along approximately with the wind.
