    Military Values in Law

    Congress, for example, takes inappropriate advantage of the tremendous deference given by courts to its constitutional powers to raise and support Armies, to provide and maintain a Navy, and to make Rules for the Government and Regulation of the land and naval Forces.\n In a court-martial involving a military defendant and a civilian victim of sexual assault, application of the psychotherapist-patient privilege raises no difficult issues related to professional military values. When both the victim and the defendant are members of the military, however, the victim\u27s assertion of privilege is at least potentially inconsistent with the victim\u27s professional obligation to place the military\u27s institutional need to discipline misconduct undermining military readiness above an individual desire not to reveal communications concerning the criminal act

    The Composition of Dust in Jupiter-Family Comets as Inferred from Infrared Spectroscopy

    Full text link
    We review the composition of Jupiter-family comet dust as inferred from infrared spectroscopy. We find that Jupiter-family comets have 10 micron silicate emission features with fluxes roughly 20-25% over the dust continuum (emission strength 1.20-1.25), similar to the weakest silicate features in Oort Cloud comets. We discuss the grain properties that change the silicate emission feature strength (composition, size, and structure/shape), and emphasize that thermal emission from the comet nucleus can have significant influence on the derived silicate emission strength. Recent evidence suggests that porosity is the dominant parameter, although more observations and models of silicates in Jupiter-family comets are needed to determine if a consistent set of grain parameters can explain their weak silicate emission features. Models of 8 m telescope and Spitzer Space Telescope observations have shown that Jupiter-family comets have crystalline silicates with abundances similar to or less than those found in Oort Cloud comets, although the crystalline silicate mineralogy of comets 9P/Tempel and C/1995 O1 (Hale-Bopp) differ from each other in Mg and Fe content. The heterogeneity of comet nuclei can also be assessed with mid-infrared spectroscopy, and we review the evidence for heterogeneous dust properties in the nucleus of comet 9P/Tempel. Models of dust formation, mixing in the solar nebula, and comet formation must be able to explain the observed range of Mg and Fe content and the heterogeneity of comet 9P/Tempel, although more work is needed in order to understand to what extent do comets 9P/Tempel and Hale-Bopp represent comets as a whole.Comment: 21 pages, 4 figures, 2 tables.

    PREDICTED VS. ESTIMATED WELFARE MEASURES: A TEST OF THE BENEFITS TRANSFER METHOD

    Get PDF
    Estimating non-market value on a site-by-site basis is a costly and time-consuming task. Benefits transfer is an alternative approach. We attempt to assess the bias and reliability of predicted value from the benefit transfer approach, using the U.S. Fish and Wildlife Services' National Survey of Fishing, Hunting and Wildlife Associated RecreationEnvironmental Economics and Policy, Resource /Energy Economics and Policy,

    Anti-lecture Hall Compositions and Overpartitions

    Full text link
    We show that the number of anti-lecture hall compositions of n with the first entry not exceeding k-2 equals the number of overpartitions of n with non-overlined parts not congruent to 0,±10,\pm 1 modulo k. This identity can be considered as a refined version of the anti-lecture hall theorem of Corteel and Savage. To prove this result, we find two Rogers-Ramanujan type identities for overpartition which are analogous to the Rogers-Ramanjan type identities due to Andrews. When k is odd, we give an alternative proof by using a generalized Rogers-Ramanujan identity due to Andrews, a bijection of Corteel and Savage and a refined version of a bijection also due to Corteel and Savage.Comment: 16 page
