    Marketing Practices of Indiana Soybean Producers

    Get PDF
    Soybean marketing decisions play a critical role in maximizing farm income. The objective of the project described here was to identify market related educational needs and to provide benchmark information for producers. The assessment was conducted through a detailed direct-mail survey. The results of the survey demonstrate differences in market access among grower operation sizes and regions, and differences in forward pricing among grower operation sizes. Farmers with large operations generally have access to more markets and are more likely to manage price risk

    Ultraproducts of measure preserving actions and graph combinatorics

    Get PDF
    Ultraproducts of measure preserving actions of countable groups are used to study the graph combinatorics associated with such actions, including chromatic, independence and matching numbers. Applications are also given to the theory of random colorings of Cayley graphs and sofic actions and equivalence relations

    Existence and stability of viscoelastic shock profiles

    Full text link
    We investigate existence and stability of viscoelastic shock profiles for a class of planar models including the incompressible shear case studied by Antman and Malek-Madani. We establish that the resulting equations fall into the class of symmetrizable hyperbolic--parabolic systems, hence spectral stability implies linearized and nonlinear stability with sharp rates of decay. The new contributions are treatment of the compressible case, formulation of a rigorous nonlinear stability theory, including verification of stability of small-amplitude Lax shocks, and the systematic incorporation in our investigations of numerical Evans function computations determining stability of large-amplitude and or nonclassical type shock profiles.Comment: 43 pages, 12 figure

    Nonlinear Decline-Rate Dependence and Intrinsic Variation of Type Ia Supernova Luminosities

    Full text link
    Published B and V fluxes from nearby Type Ia supernovae are fitted to light-curve templates with 4-6 adjustable parameters. Separately, B magnitudes from the same sample are fitted to a linear dependence on B-V color within a post-maximum time window prescribed by the CMAGIC method. These fits yield two independent SN magnitude estimates B_max and B_BV. Their difference varies systematically with decline rate Delta m_15 in a form that is compatible with a bilinear but not a linear dependence; a nonlinear form likely describes the decline-rate dependence of B_max itself. A Hubble fit to the average of B_max and B_BV requires a systematic correction for observed B-V color that can be described by a linear coefficient R = 2.59 +- 0.24, well below the coefficient R_B ~ 4.1 commonly used to characterize the effects of Milky Way dust. At 99.9% confidence the data reject a simple model in which no color correction is required for SNe that are clustered at the blue end of their observed color distribution. After systematic corrections are performed, B_max and B_BV exhibit mutual rms intrinsic variation equal to 0.074 +- 0.019 mag, of which at least an equal share likely belongs to B_BV. SN magnitudes measured using maximum-luminosity or CMAGIC methods show comparable rms deviations of order ~ 0.14 mag from the Hubble line. The same fit also establishes a 95% confidence upper limit of 486 km/s on the rms peculiar velocity of nearby SNe relative to the Hubble flow.Comment: 21 pages, 11 figures, 10 tables, to appear in The Astrophysical Journal, uses emulateapj_051214.cl

    Barack Obama and the Rhetoric of Electoral Logic

    Get PDF
    Objectives This article examines Barack Obama\u27s efforts to interpret and characterize the contrasting outcomes of the 2008 and 2010 elections, using an original data set of presidential communications. Methods We performed a content analysis of 241 presidential communications. Results Obama\u27s post-2008 mandate claims alternated between claiming a mandate on a variety of policy issues and framing the election as a repudiation of Republican theories of governing. Post-2010, however, Obama framed the midterm results as evidence for electoral demand for bipartisan cooperation, rather than a repudiation of Democratic policies and ideas. Conclusions Obama\u27s choices in framing the 2008 election contributed to the administration\u27s failure to communicate effectively. Specifically, Obama neglected to create a strong narrative linking the election\u27s results to support for his policy agenda, focusing instead on the election as a repudiation of Republican policies. In contrast, his interpretations of the 2010 midterms appear to be more effective. By identifying the Republicans\u27 behavior as “dysfunctional” and conceding that the election had indicated a demand for the ideas of both parties, Obama offered a more successful alternative to the Republican narrative
