In the months after the contested Iranian presidential election in June 2009, Iranians spoke out about the election using Twitter — a social media service that allows users to send short text messages, called tweets, with relative anonymity. This research analyzed more than 2.5 million tweets discussing the Iran election that were sent in the nine months following it, drawing insights into Iranian public and mood in the post-election period.

It has become clear that Stuxnet-like worms pose a serious threat even to critical U.S. infrastructure and computer systems that are not connected to the Internet. However, defending against such attacks involves complex technological and legal issues. In particular, at the federal level, different organizations have different responsibilities and levels of authority when it comes to investigating or defending against intrusions.

The Modified Kalman Filter approach for pooling information across time and outcomes is shown to improve accuracy in national estimates of health outcomes including cancer, diabetes, and hypertension especially in small racial/ethnic subgroups. The developed SAS macro models true health states in each subgroup assuming a linear time evolution and an autoregressive deviation around such trend. The macro provides multiple options for users.

Congressional concern with cost overruns, or breaches, in several major defense acquisition programs led the authors, in a partnership with the Performance Assessments and Root Cause Analysis Office in the Office of the Secretary of Defense, Acquisition, Technology, and Logistics, to investigate root causes by examining program reviews, analyzing data, participating in contractor briefings, and holding meetings with diverse stakeholders.

Geographic information system (GIS) mapping software is a promising tool for enhancing priority-setting and resource allocation in local health departments (LHDs) by displaying complex geospatial information in an integrated, visual way, enabling comparison of where health services are needed with where they are provided. The study describes options for accessing GIS data and suggests ways for LHDs to integrate GIS into their planning activities.

There has been an overall downward trend in the use of National Aeronautics and Space Administration (NASA) wind-tunnel test facilities, and fiscal pressures have increased incentives to cut costs and create additional sources of revenue. The authors explore six potential approaches to pricing the use of these facilities and evaluate each approach against three criteria — efficiency, fiscal impact, and fairness.

This technical report describes the benefits of reallocating certain maintenance activities between mission-generation locations and a repair network, options to support the C-130, and consolidating repair network activities to centralized repair facilities. The report also provides an initial assessment of maintenance concepts that integrate wing-level and depot-level maintenance processes.

This report presents results of a preliminary assessment of the National Science Foundation's National Science Digital Library/Distributed Learning (NSDL) program based largely on existing data and makes recommendations for the design of a full formative evaluation. The authors explore the state of health of the STEM resource collections, the availability of web metrics to probe their use, and the potential usability and impact of NSDL-funded materials on STEM teaching and learning.

Any successful response to climate change--both the challenges of limiting the magnitude of future climate change and adapting to its impacts--will clearly involve policies that evolve over time in response to new information and that are robust over a wide range of difficult-to-predict future conditions.
