    [Review of] Victoria Wyatt. Shapes of Their Thoughts: Reflections of Culture Contacts in Northwest Coast Indian Art

    Get PDF
    An exhibition at the Yale Peabody Museum of Natural History in New Haven, Connecticut, was held from November 1983 to May 1984. The exhibit focused on 200 years of the creative responses of Northwest Coast Indian artists to interactions with explorers, fur traders, missionaries, businessmen, tourists and ethnographers from a variety of cultures

    An improved rocket-borne electric field meter for the middle atmosphere

    Get PDF
    Improvements in a rocketborne electric field meter designed to measure the atmosphere's electric field and conductivity in the middle atmosphere are described. The general background of the experiment is given as well as changes in the instrument and data processing schemes. Calibration and testing procedures are documented together with suggestions for future work

    Population connectivity among Dry Tortugas, Florida, and Caribbean populations of mutton snapper (Lutjanus analis), inferred from multiple microsatellite loci

    Determining patterns of population connectivity is critical to the evaluation of marine reserves as recruitment sources for harvested populations. Mutton snapper (Lutjanus analis) is a good test case because the last known major spawning aggregation in U.S. waters was granted no-take status in the Tortugas South Ecological Reserve (TSER) in 2001. To evaluate the TSER population as a recruitment source, we genotyped mutton snapper from the Dry Tortugas, southeast Florida, and from three locations across the Caribbean at eight microsatellite loci. Both Fstatistics and individual-based Bayesian analyses indicated that genetic substructure was absent across the five populations. Genetic homogeneity of mutton snapper populations is consistent with its pelagic larval duration of 27 to 37 days and adult behavior of annual migrations to large spawning aggregations. Statistical power of future genetic assessments of mutton snapper population connectivity may benefit from more comprehensive geographic sampling, and perhaps from the development of less polymorphic DNA microsatellite loci. Research where alternative methods are used, such as the transgenerational marking of embryonic otoliths with barium stable isotopes, is also needed on this and other species with diverse life history characteristics to further evaluate the TSER as a recruitment source and to define corridors of population connectivity across the Caribbean and Florida

    Long Duration Exposure Facility: A general overview

    Get PDF
    The Long Duration Exposure Facility (LDEF) is a large, low-cost, reusable, unmanned, free-flying spacecraft which accommodates technology, science, and applications experiments for long-term exposure to the space environment. The LDEF was designed and built by the NASA Langley Research Center (LaRC) for NASA's Office of Aeronautics and Space Technology. Specifically, the LDEF was designed to transport experiments into space via the Space Shuttle, to free fly in Earth orbit for an extended period, and be retrieved on a later Space Shuttle flight allowing experiments to be returned to Earth for postflight analysis in the laboratory. The LDEF with a full complement of experiments was placed in Earth orbit in April 1984 by Challenger and retrieved from orbit in January 1990 by Columbia. A general overview of the LDEF, its mission, systems, experiments, and operations is presented. Excerpts from various NASA documents are extensively used

    Deregulation for Development: A Tale of Two States

    Get PDF
    Economic stress led South Dakota and Delaware in the early 1980’s to eliminate their usury laws and enact other enabling legislation in an effort to attract a new industry and new jobs to their states. Sufficient time has now elapsed to assess the success of the policies adopted by these two states. Evidence suggests that both states benefited from their deregulatory actions but in different ways. These successful deregulations provide an important lesson for state-level authorities responsible for determining the regulatory environment.Regional Development, Deregulation, State Government Public Policy
