Characterization of Turbulence from Submillimeter Dust Emission

In this paper we use our recent technique for estimating the turbulent component of the magnetic field to derive the structure functions of the unpolarized emission as well as that of the Stokes Q and U parameters of the polarized emission. The solutions for the structure functions to 350-um SHARP polarization data of OMC-1 allow the determination of the corresponding turbulent correlation length scales. The estimated values for these length scales are 9.4" +/- 0.1", 7.3" +/- 0.1", 12.6" +/- 0.2" (or 20.5 +/- 0.2, 16.0 +/- 0.2, and 27.5 +/- 0.4 mpc at 450 pc, the adopted distance for OMC-1) for the Stokes Q and U parameters, and for the unpolarized emission N, respectively. Our current results for Q and U are consistent with previous results obtained through other methods, and may indicate presence of anisotropy in magnetized turbulence. We infer a weak coupling between the dust component responsible for the unpolarized emission N and the magnetic field B from the significant difference between their turbulent correlation length scales.Comment: 14 pages, 3 figures; accepted for publication in the Ap

Off-the-Record Consultations and the Revised Model State Administrative Procedure Act

The drafters of the Revised Act have sought to resolve the confrontation of policy objectives in part by insisting that the decision maker refrain from off-the-record communications with any of the parties to the proceeding. However, there are a number of ambiguities in the act which indicate that it may be possible for state agencies to avoid this objective. Furthermore, implementation of the policy decisions of the drafters may prove to be undesirable for the overall operation of state administrative agencies. This comment will consider these two possible criticisms of the Revised Model Act and will suggest that changes be made in the language of certain provisions when enacted by state legislatures
