Designing for Deeper Learning in a Blended Computer Science Course for Middle School Students
The focus of this research was to create and test an introductory computer science course for middle school. Titled “Foundations for Advancing Computational Thinking” (FACT), the course aims to prepare and motivate middle school learners for future engagement with algorithmic problem solving.

Weakness in Depth: A Voting Machine’s Demise
Virginia’s government recently examined the AVS WinVote and learned that the vulnerabilities are more serious than any other voting system, allowing complete exploitation over a Wi-Fi network.

Practical Measures of Learning Behaviors
This paper argues that improving learning reliably and at scale requires a specific orientation toward measurement, understood broadly.

Classification of Lexical Stress Using Spectral and Prosodic Features for Computer-assisted Language Learning Systems
We present a system for detection of lexical stress in English words spoken by English learners. This system was designed to be part of the EduSpeak® computer-assisted language learning (CALL) software.

Pharmacological Characterization of RO5461861, a Potent and Selective PDE10A Inhibitor
We describe the characterization of a new class of potent PDE10A inhibitors exemplified by 4-(Azetidine-1 -carbonyl)-2-methyl-2-H-pyrazole-3-carboxylic acid (2-phenylimidazo[1,2-a]pyrimidin-7-yl)-amide (RO5461861) in vitro as well as in behavioral tests relevant to NMDA-R hypofunction and working memory.

Biodistribution of the Multidentate Hydroxypyridinonate Ligand [(14) C]-3,4,3-Li(1,2-HOPO), a Potent Actinide Decorporation Agent
The pharmacokinetics and biodistribution of the 14C-labeled actinide decorporation agent 3,4,3-LI(1,2-HOPO) were investigated in young adult Swiss Webster mice and Sprague Dawley rats, after intravenous, intraperitoneal, and oral dose administration.

High Frequency Neuronal Oscillations in a Cynomolgus Macaque Test of Working Memory Following NMDA Receptor Antagonism
Disruptions in sensory processing and abnormal temporal integration of neuronal oscillations have been identified in schizophrenic patients and may contribute to poor performance in working memory task testing.

Assessments for Computational Thinking in K-12
This paper argues for the need for multiple measures or “systems of assessments” that are complementary, attend to cognitive and non-cognitive aspects of CT, and contribute to a comprehensive picture of student learning.

Towards community-centered support for peer-to-peer service exchange: rethinking the timebanking metaphor
We conducted a field study of the most prominent of these, timebanking; a system in which ‘time dollars’ are earned and spent by people providing services for and receiving them from each other.

Simulation, Design, Fabrication, and Testing of a Mems Resettable Circuit Breaker
We describe a novel concept for a microelectromechanical systems (MEMS) resettable circuit breaker. The concept involves fabricating the circuit breaker and the reset switch using a single microcantilever.

The Convergence of Mobility, Personalization and Security
New product innovation is as much about making advanced technology accessible to a broader market as it is about adding wow-factor features. Iris authentication—once a niche component of high-end security systems—will debut in compact, cost-competitive form factors at this year’s ISC West security industry trade show. SRI International will demonstrate several new Iris on the Move®-powered solutions, including…
