    Survey of Federal Whistleblower and Anti-Retaliation Laws

    Get PDF
    This report provides an overview of federal whistleblower and anti-retaliation laws. In general, these laws protect employees who report misconduct by their employers or who engage in various protected activities, such as participating in an investigation or filing a complaint. In recent years, Congress has expanded employee protections for a variety of private-sector workers. Eleven of the forty laws reviewed in this report were enacted after 1999. Among these laws are the Sarbanes-Oxley Act, the FDA Food Safety Modernization Act, and the Dodd-Frank Wall Street Reform and Consumer Protection Act. The report focuses on key aspects of the federal whistleblower and anti-retaliation laws. For each law, the report summarizes the activities that are protected, how the law’s protections are enforced, whether the law provides a private right of action, the remedies prescribed by the law, and the year the law’s whistleblower or anti-retaliation provisions were adopted and amended. With regard to amendment dates, the report identifies only dates associated with substantive amendments. For enactments after 2001, the report provides information on congressional sponsorship and votes

    Faddeev calculations of break-up reactions with realistic experimental constraints

    Full text link
    We present a method to integrate predictions from a theoretical model of a reaction with three bodies in the final state over the region of phase space covered by a given experiment. The method takes into account the true experimental acceptance, as well as variations of detector efficiency, and eliminates the need for a Monte-Carlo simulation of the detector setup. The method is applicable to kinematically complete experiments. Examples for the use of this method include several polarization observables in dp break-up at 270 MeV. The calculations are carried out in the Faddeev framework with the CD Bonn nucleon-nucleon interaction, with or without the inclusion of an additional three-nucleon force.Comment: 18 pages, 9 figure

    Analyzing Powers and Spin Correlation Coefficients for p+d Elastic Scattering at 135 and 200 MeV

    Get PDF
    The proton and deuteron analyzing powers and 10 of the possible 12 spin correlation coefficients have been measured for p+d elastic scattering at proton bombarding energies of 135 and 200 MeV. The results are compared with Faddeev calculations using two different NN potentials. The qualitative features of the extensive data set on the spin dependence in p+d elastic scattering over a wide range of angles presented here are remarkably well explained by two-nucleon force predictions without inclusion of a three-nucleon force. The remaining discrepancies are, in general, not alleviated when theoretical three-nucleon forces are included in the calculations.Comment: 43 pages, 12 figures, accepted for publication by Phys.

    A consistent methodology for the derivation and calibration of a macroscopic turbulence model for flows in porous media

    Get PDF
    This work aims to model turbulent flows in media laden with solid structures according to porous media approach. A complete set of macroscopic transport equations is derived by spatially averaging the Reynolds averaged governing equations. A two-scale analysis highlights energy transfers between macroscopic and sub-filter kinetic energies (dispersive and turbulent kinetic energies). Additional terms coming from the averaging procedure and representing solids/fluid interactions and turbulent contributions are modeled. Connections between turbulence modeling and dispersion modeling are presented. Other closure expressions are determined using physical considerations and spatial averaging of microscopic computations. A special care is given to the calibration methodology for the phenomenological coefficients. Results of the present model are successfully compared to volume-averaged reference results coming from fine scale computations and show significant improvements with respect to previous macroscopic models
