The closure of the Hawaiian longline swordfish fishery over the period 2001–2004, which was motivated by the protection of endangered sea turtles, created the elements of a natural experiment that allows identification of the market transfer of catch (and sea turtle bycatch) to other regions. This paper exploits the fact that the vessels in the Hawaiian… (More)
(NIST) promotes the U.S. economy and public welfare by providing technical leadership for the Nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analyses to advance the development and productive use of information technology. ITL's responsibilities include the… (More)
Although the word "mentor"has traditionally been used to describe a relationship between an older adult and a younger person, recent work has extended its usage to relationships with peers and groups rather than with individuals and uncoupled the instrumental and affective qualities of the role. This paper examines (a) the extent to which adolescents'… (More)
Children with reading comprehension difficulties display impaired performance on semantic processing tasks. These impairments are assumed to reflect weaker knowledge about abstract semantic associations between words in poor comprehenders [Nation, K., and Snowling, M. (1999). Developmental differences in sensitivity to semantic relations among good and poor… (More)
Auburn University, through the Army's Aviation and Missile Research, Development and Engineering Center (AMRDEC) has been supporting the Unmanned Systems Initiative (USI) program in three research areas related to unmanned aerial vehicle (UAV). A major element in this work is the development of a high fidelity modeling and simulation testbed to support the… (More)
In 1971, a grant from the National Science Foundation (NSF) to Michigan State University provided funds for the construction of 18 experimental ponds, two holding ponds and a reservoir.pond construction Each experimental pond was approximately 30 m in dia. with a maximum depth of 2 m and was lined with vinyl plastic to prevent seepage losses. The liners in… (More)
We explore development of a high-fidelity simulation testbed for various network architectures for communication between components of tactical unmanned aerial systems, and for distribution of intelligence gathered by these systems.
