Early College High School Initiative: 2003-2005 Evaluation Report
This report is the second annual synthesis report on the national evaluation of the Bill & Melinda Gates Foundation ’s Early College High School Initiative (ECHSI). The foundation established the vision for the ECHSI. At its most basic, this vision is summarized in a set of Core Principles, which includes the requirements that ECHSs provide…

Compositionality for Tightly Coupled Systems: a New Application of the Propositions-As-Types Interpretation
Although compositional techniques are being successfully employed in practice, the use of such techniques is often rather informal and intuitive, and typically a justification for correct behaviour of the composed system exists but is not expressed explicitly. In this paper, we show what can be gained from treating such justifications as first-class citizens.

Conflict Negotiation Among Personal Calendar Agents
We will demonstrate distributed conflict resolution in the context of personalized meeting scheduling. The demonstration will show how distributed constraint optimization can be used to facilitate interaction between cognitive agents and their users. The system is part of the CALO personal cognitive assistant that will also be explored during the demonstration.

Generalized Linear Kernels for One-Versus-All Classification: Application to Speaker Recognition
In this paper, we examine the problem of kernel selection for one-versus-all (OVA) classification of multiclass data with support vector machines (SVMs). We focus specifically on the problem of training what we refer to as generalized linear kernels–that is, kernels of the form, k(x_1,x_2) = x_1^T R x_2, where R is a positive semidefinite matrix.

Measuring Middle School Teachers’ Mathematical Knowledge Of Teaching Rate And Proportionality
We are investigating if teachers from across the state of Texas can use a specially designed replacement unit and SimCalc software to help their students learn mathematics important to the Texas state frameworks, as well as content that goes beyond the state framework—the beginning pieces of the “mathematics of change,” leading to Calculus.
