The Federal Aviation Administration (FAA) manages US airspace to promote safe and efficient operations. The FAA is presently revamping its infrastructure to accommodate new air traffic control (ATC) services and to reduce risks associated with cyber threats. A description of the cyber security architecture, being deployed, is provided. The transition from a(More)
Purpose – Within the theoretical context of human security, this United Nations (UN) three-year research project examines the causes and effects of conflicts in the arid and semi-arid lands of Northern Kenya. The purpose of this paper is to address the human security concerns arising out of conflict, displacement, migration and poverty. The people who live(More)
Twenty-two young children, maintained on a diet that excluded certain foods, were challenged intermittently with a blend of seven artificial colors in a double-blind trial. Parents' observations provided the criteria of response. One child that responded mildly to the challenge and one that responded dramatically were detected. The latter, a 34-month-old(More)
Several states and countries have adopted targets for deep reductions in greenhouse gas emissions by 2050, but there has been little physically realistic modeling of the energy and economic transformations required. We analyzed the infrastructure and technology path required to meet California's goal of an 80% reduction below 1990 levels, using detailed(More)
This memorandum addresses three issues concerning the use of unmanned aircraft for newsgathering: (1) whether members of the media may use unmanned aircraft systems (UAS) for newsgathering; (2) whether the media may use pictures, video, or other infmmation collected by a person using UAS; and (3) whether a person who sells images collected by UAS would need(More)
Jurisdictions throughout the world are contemplating greenhouse gas (GHG) miti-gation strategies that will enable meeting long-term GHG targets. Many jurisdictions are now focusing on the 2020–2050 timeframe. We conduct an inter-model comparison of nine California statewide energy models with GHG mitigation scenarios to 2050 to better understand common(More)
Behavioral toxicology in the natural environment can be considered a special branch of epidemiology. Behavioral epidemiology, because it typically relies on complex functional criteria, faces all of the problems of behavior measurement posed by uncontrollable variation, and amplified even further by chemical exposure. Many such issues arose in a study of(More)
