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

U.S. Health Care Spending: Comparison with Other OECD Countries
[Excerpt] The United States spends more money on health care than any other country in the Organization for Economic Cooperation and Development (OECD). The OECD consists of 30 democracies, most of which are considered the most economically advanced countries in the world. According to OECD data, the United States spent $6,102 per capita on health care in 2004 — more than double the OECD average and 19.9% more than Luxembourg, the second-highest spending country. In 2004, 15.3% of the U.S. economy was devoted to health care, compared with 8.9% in the average OECD country and 11.6% in second-placed Switzerland. Why does the United States spend this amount on health care? Economists break health care spending into two parts: price and quantity (which includes the number of visits to health care providers and the intensity of those visits). In terms of quantity, OECD data indicate that the United States has far fewer doctor visits per person compared with the OECD average; for hospitalizations, the United States ranks well below the OECD and is roughly comparable in terms of length of hospital stays. The intensity of service delivery is a different story: the United States uses more of the newest medical technologies and performs several invasive procedures (such as coronary bypasses and angioplasties) more frequently than the average OECD country. In terms of price, the OECD has stated that there is no doubt that U.S. prices for medical care commodities and services are significantly higher than in other countries and serve as a key determinant of higher overall spending. What does the United States get for the money it spends? Said slightly differently, does the United States get corresponding value from the money it spends on health care? The available data often do not provide clear answers. For example, among OECD countries in 2004, the United States had shorter-than-average life expectancy and higher-than-average mortality rates. Does this mean that the U.S. system is inefficient in light of how much is spent on health care? Or does this reflect the greater prevalence of certain diseases in the United States (the United States has the highest incidence of cancer and AIDS in the OECD) and less healthy lifestyles (the United States has the highest obesity rates in the OECD)? These are some of the issues that confound international comparisons. However, research comparing the quality of care has not found the United States to be superior overall. Nor does the U.S. population have substantially better access to health care resources, even putting aside the issue of the uninsured. Although the United States does not have long wait times for non-emergency surgeries, unlike some OECD countries, Americans found it more difficult to make same-day doctor’s appointments when sick and had the most difficulty getting care on nights and weekends. They were also most likely to delay or forgo treatment because of cost. The OECD data and other research provide some insight as to why health care spending is higher in the United States than in other countries, although many difficult research issues remain. This report presents some of the available data and research and concludes with a summary of study findings
An improved rocket-borne electric field meter for the middle atmosphere
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
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
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
