In 2008, a group of uninsured low-income adults in Oregon was selected by lottery to be given the chance to apply for Medicaid. This lottery provides an opportunity to gauge the effects of expanding access to public health insurance on the health care use, financial strain, and health of low-income adults using a randomized controlled design. In the year after random assignment, the treatment g...
We report on the design and performance of the Bicep2 instrument and on its three-year data set. Bicep2 was designed to measure the polarization of the cosmic microwave background (CMB) on angular scales of 1◦–5◦( = 40–200), near the expected peak of the B-mode polarization signature of primordial gravitational waves from cosmic inflation. Measuring B-modes requires dramatic improvements in sen...
This paper summarizes a long-term project to install and maintain socially interactive, autonomous mobile robots in public spaces. We have deployed four robots over the past five years, accumulating a total operational time exceeding seven years. This document introduces the robots, then focuses on lessons learned from each deployment. Finally, this paper describes how this entire project came ...
Let X be a definable C manifold, Y1, Y2 definably compact definable C r submanifolds of X such that dimY1 + dimY2 < dimX and Y1 has a trivial normal bundle. We prove that there exists a definable isotopy {hp}p∈J such that h0 = idX and h1(Y1) ∩ Y2 = ∅. 2010 Mathematics Subject Classification. 14P10, 14P20, 58A05, 03C64.
Project-based learning is an essential part of a software engineer's education. The learning achieved through projects can be improved through structured interaction between more experienced students and those students encountering their rst software engineering project. In this paper, we report on our experience over three years with trials of several forms of interaction between undergraduate...
Future system development and management efforts must strive to institutionalize these gains and provide ongoing, incremental improvement in these areas. With the growth of e-commerce and further socioeconomic reliance on IT, the organizations that have achieved these gains will be well positioned to outdistance those who were less aggressive. Figure 1 depicts the silver linings and competitive...

Y2K presented a formidable (albeit welldefined) challenge: find the date problems and fix them (see our “Congratulations” in the accompanying sidebar). Post-Y2K presents a more formidable challenge: a...
