Run for your life: Spectacle primaries and the success of \u27failed\u27 primary candidates
This thesis qualitatively examines the personal career outcomes of major presidential primary candidates from 1976-2008. It argues that the primary process fundamentally changed with the introduction of reform in the 1970s. It has continued to evolve into the spectacle primary, a system whereby mere participation, not necessarily electoral success, can convey manifold benefits to subsequent careers in the public or private sectors. It also finds far less risk in primary participation than conventional wisdom might assume. Therefore, this thesis holds that prospective candidates when weighing a presidential primary bid, should consider these ulterior benefits beyond electoral success and all else being equal, they should decide to enter presidential primary contests

Federated learning enables big data for rare cancer boundary detection.
Although machine learning (ML) has shown promise across disciplines, out-of-sample generalizability is concerning. This is currently addressed by sharing multi-site data, but such centralization is challenging/infeasible to scale due to various limitations. Federated ML (FL) provides an alternative paradigm for accurate and generalizable ML, by only sharing numerical model updates. Here we present the largest FL study to-date, involving data from 71 sites across 6 continents, to generate an automatic tumor boundary detector for the rare disease of glioblastoma, reporting the largest such dataset in the literature (n = 6, 314). We demonstrate a 33% delineation improvement for the surgically targetable tumor, and 23% for the complete tumor extent, over a publicly trained model. We anticipate our study to: 1) enable more healthcare studies informed by large diverse data, ensuring meaningful results for rare diseases and underrepresented populations, 2) facilitate further analyses for glioblastoma by releasing our consensus model, and 3) demonstrate the FL effectiveness at such scale and task-complexity as a paradigm shift for multi-site collaborations, alleviating the need for data-sharing
