Matroids and Geometric Invariant Theory of torus actions on flag spaces

We apply a theorem of Gel'fand, Goresky, MacPherson, and Serganova about matroid polytopes to study semistability of partial flags relative to a T-linearized ample line bundle of a flag space F = SL(n)/P where T is a maximal torus in SL(n) and P is a parabolic subgroup containing T. We find that the semistable points are all detected by invariant sections of degree one regardless of the line bundle or linearization thereof, provided there exists at least one nonzero invariant section of degree one. In this case the degree one sections are sufficient to give a well defined map from the G.I.T. quotient F//T to projective space. Additionally, we show that the closure of any T-orbit in SL(n)/P is a projectively normal toric variety for any projective embedding of SL(n)/P.Comment: 14 page

2023 TCPEA Outstanding Dissertation of the Year Research Summary

This phenomenological study explored perceived first-generation college student retention at a Texas four-year higher education institution post-vertical transfer. The participants in this study consisted of 12 full-time and part- time students who identified as first-generation college students and had vertically transferred from a two-year higher education institution. In addition, participants transferred between 35 and 120 academic credit hours from a two-year higher education institution and had been enrolled for at least one academic semester at their four-year higher education institution. On-campus and virtual semi-structured interviews were conducted and analyzed, which resulted in major themes. This study revealed academic and social integration were crucial to retaining first-generation college students post-vertical transfer. In addition, this study identified key support services that the population perceived as the most beneficial in aiding their retention. As a result, this study’s implications can aid four-year higher education institutions in developing effective practices and programs to retain and support first-generation vertical transfer students

Documentary video dissertation in American Studies

The production of documentary videos has been an innovative and dynamic feature of course delivery in the Department of American and Canadian Studies. The Department is now building on this experience to introduce an audio-visual documentary dissertation as an option for Single Honours students. The project examines - Design of a WebCT course and further training elements to support students in the making of the documentary video dissertation. They will also develop a training programme in documentary video production, including camerawork, storyboarding and editing techniques - Creation of a WebCT course to support training and documentary dissertation, and a linked website to chart progres
