The social sciences can play important roles in assisting military planners and decision-makers who are trying to understand complex human social behaviors and systems, potentially facilitating a wide range of missions including humanitarian, stability, and counter-insurgency operations. Current social science approaches to studying behavior rely on a variety of modeling methods—both qualitative and quantitative—which seek to make inferences about the causes of social phenomena on the basis of observations in the real-world. Yet little is known about how accurate these methods and models really are, let alone whether the connections they observe and predict are truly matters of cause and effect or mere correlations.
The February 2011 Federal Cloud Computing Strategy released by the U.S. Chief Information Officer reinforces the United States Government’s plans to move information technology away from traditional workstations and toward cloud computing environments. Where compelling incentives to do this exist, security implications of concentrating sensitive data and computation into computing clouds have yet to be fully addressed. The perimeter defense focus of traditional security solutions is not sufficient to secure existing enclaves. It could be further marginalized in cloud environments where there is a huge concentration of homogeneous hosts on high-speed networks without internal checks, and with implicit trust among hosts within those limited perimeter defenses.
The Mobile Hotspots program envisions air, mobile and fixed assets that provide a gigabit-per-second tactical millimeter-wave backbone network extending to the lowest-echelon warfighters.
The Network Universal Persistence (Network UP) program seeks to develop and demonstrate radio technology that maintains network reliability through periods of frequent signal degradation that may occur during operations in multiple environments. From time to time, network outages may occur and data transmission may be challenged.
The explosive growth of global digital connectivity has opened new possibilities for designing and conducting social science research. Once limited by practical constraints to experiments involving just a few dozen participants-often university students or other easily available groups-or to correlational studies of large datasets without any opportunity for determining causation, scientists can now engage thousands of diverse volunteers online and explore an expanded range of important topics and questions.
