Modeling radiation belt radial diffusion in ULF wave fields: 1. Quantifying ULF wave power at geosynchronous orbit in observations and in global MHD model

[1] To provide critical ULF wave field information for radial diffusion studies in the radiation belts, we quantify ULF wave power (f = 0.5–8.3 mHz) in GOES observations and magnetic field predictions from a global magnetospheric model. A statistical study of 9 years of GOES data reveals the wave local time distribution and power at geosynchronous orbit in field-aligned coordinates as functions of wave frequency, solar wind conditions (Vx, ΔPd and IMF Bz) and geomagnetic activity levels (Kp, Dst and AE). ULF wave power grows monotonically with increasing solar wind Vx, dynamic pressure variations ΔPd and geomagnetic indices in a highly correlated way. During intervals of northward and southward IMF Bz, wave activity concentrates on the dayside and nightside sectors, respectively, due to different wave generation mechanisms in primarily open and closed magnetospheric configurations. Since global magnetospheric models have recently been used to trace particles in radiation belt studies, it is important to quantify the wave predictions of these models at frequencies relevant to electron dynamics (mHz range). Using 27 days of real interplanetary conditions as model inputs, we examine the ULF wave predictions modeled by the Lyon-Fedder-Mobarry magnetohydrodynamic code. The LFM code does well at reproducing, in a statistical sense, the ULF waves observed by GOES. This suggests that the LFM code is capable of modeling variability in the magnetosphere on ULF time scales during typical conditions. The code provides a long-missing wave field model needed to quantify the interaction of radiation belt electrons with realistic, global ULF waves throughout the inner magnetosphere

Anxiety and Focus in Work-Related Training

Currently, nonemployee students who take General Electric\u27s (GE\u27s) pollution control classes do not demonstrate consistent knowledge gains following training. The purpose of this project was to investigate whether the independent variables of level of education and choice in attending the class made a significant difference in the means of the dependent variables of anxiety and ability to focus. The project was influenced by the theory of andragogy, which explores the motivations and principles specific to the teaching of adults. The research questions for this study probed relationships between level of formal education among participants and their choice in whether to attend or not and potential anxiety towards training and their ability to focus on training. Data were collected from 756 adults who took a voluntary self-designed survey while registering for this class. A quantitative approach that included t tests and ANOVA tests revealed significant differences when comparing the adult behaviors of anxiety and ability to focus with the variables of choice in attendance of training and level of completed formal education. The results were used to inform a train-the-trainer program with the goal of mitigating discrepancies in knowledge transfer. As the impacts of pollution are understood, it is critical that those who are responsible for controlling pollution have the best training. Organizations that issue professional certifications need to be assured that those completing continuing education units deserve the awarded credits. Thus, any improvement to the consistency of knowledge transferred for GE\u27s pollution control classes will support social change by enhancing the ability of students of the class to protect the earth\u27s communities and climate and fulfill education obligations

Structural Characteristics Of Sr1-xLaxTi 3+δ As A Function Of Oxygen Partial Pressure At 1400°C

The structural characteristics of Sr1-x Lax TiO3+δ (0≤x≤0.4) at 1400°C have been investigated as a function of ambient oxygen partial pressure. A modified Rietveld pattern-fitting structure-refinement program [H. M. Rietveld, J. Appl. Crystallogr. 2, 65 (1969)] was used to determine the nature of the distortions of the fundamental perovskite unit cell, the degree of lattice perfection, and the cation vacancy concentrations. Specimens equilibrated in forming gas displayed a linear relation between x, the lattice parameters, and the degree of lattice perfection while those samples annealed in air and oxygen deviated significantly from linearity. A monoclinic distortion of the perovskite structure was seen in the samples at low oxygen partial pressures while a second phase or layer type of distortion appeared in samples with x\u3e0.2 under oxidizing conditions

X‐ray Powder Diffraction Structural Phase‐Transition Study Of La(Cr1‐xMnx)O3 (x = 0 To 0.25) Using The Rietveld Method Of Analysis

The La(Cr1‐xMnx)O3 (x = 0 to 0.25) system exhibited a displacive phase transformation from an orthorhombic to a rhombohedral structure at temperatures ranging from about 256°C at x= 0 to 305°C at x= 0.25. The Rietveld method of X‐ray analysis was used to determine structural characteristics and to assay phase concentrations when multiple phases were present. Indications were that the Mn ions on the B site affected the transition temperature through an ionic size effect; i.e., Mn3+, with a larger ionic size than Cr3+, increased the transition temperature while the presence of the smaller Mn4+ ions reduced it. A hysteresis was also observed with respect to the phase transformation as a function of temperature. The phase transformation was associated with a change in the rotation of the oxygen octahedra from an antiphase to an in‐phase tilt sequence. Copyright © 1992, Wiley Blackwell. All rights reserve

Examining Periodic Solar Wind Density Structures Observed in the SECCHI Heliospheric Imagers

We present an analysis of small-scale, periodic, solar-wind density enhancements (length-scales as small as \approx 1000 Mm) observed in images from the Heliospheric Imager (HI) aboard STEREO A. We discuss their possible relationship to periodic fluctuations of the proton density that have been identified at 1 AU using in-situ plasma measurements. Specifically, Viall, Kepko, and Spence (2008) examined 11 years of in-situ solar-wind density measurements at 1 AU and demonstrated that not only turbulent structures, but also non-turbulent periodic density structures exist in the solar wind with scale sizes of hundreds to one thousand Mm. In a subsequent paper, Viall, Spence, and Kasper (2009) analyzed the {\alpha} to proton solar-wind abundance ratio measured during one such event of periodic density structures, demonstrating that the plasma behavior was highly suggestive that either temporally or spatially varying coronal source plasma created those density structures. Large periodic density structures observed at 1 AU, which were generated in the corona, can be observable in coronal and heliospheric white-light images if they possess sufficiently high density contrast. Indeed, we identify such periodic density structures as they enter the HI field of view and follow them as they advect with the solar wind through the images. The smaller periodic density structures that we identify in the images are comparable in size to the larger structures analyzed in-situ at 1 AU, yielding further evidence that periodic density enhancements are a consequence of coronal activity as the solar wind is formed.Comment: 15 pages, 12 figures.

Baker Center Journal of Applied Public Policy, Vol. III No. I

Welcome to the third issue of the Baker Center Journal for Applied PublicPolicy. I am pleased that this issue, as its predecessors, evidences the vibrancy of the Baker Center’s governance and public policy programs and makes a contribution to our collective understanding about a variety of policy issues currently being discussed in America. Relating to our system of governance, Jess Hale Jr. examines a proposal for a uniform state approach to reining in renegade presidential electors and Professor Glenn Reynolds reviews Jack Goldsmith’s book The Terror Presidency: Law and Judgment Inside the Bush Administration. Relating to media and foreign affairs and the role of the media in political life, Dr. Mike Fitzgerald and two of his students provide us with “A Comparative Study of Images Created by Press Coverage of the United States and the Republic of Belarus.” Relating to health policy, Dr. David Mirvis, recently appointed as a Senior Fellow for Health Policy at the Center, explores the public policy implications of viewing health as an engine of economic growth. Relating to energy and environmental policy, Drs. Bruce Tonn and Amy Gibson and Baker Scholars Stephanie Smith and Rachel Tuck explore U.S. Attitudes and Perspectives on National Energy Policy. I am also very pleased that this issue includes a report of an excellent conference – “Formulation of a Bipartisan Energy and Climate Policy: Toward and Open and Transparent Process “- that was co-sponsored by the Baker Center and the Woodrow Wilson International Center for Scholars. This issue also includes the result ofanother successful collaboration between the Baker and Wilson Centers that focused on “Five Public Policy Ideas for Building Obama’s New Economy.” I look forward to further productive collaborations between the Baker and Wilson Centers. Relating to global security policy, this issue includes a Student Symposium onNational Security. Although the Baker Center Journal has provided an outlet for publication of student scholarship since its inception, I am particularly pleased that the student co-editors - Baker Scholars Elizabeth Wilson Vaughan and Bradford A. Vaughan - took the initiative to expand upon the efforts of their predecessors and to provide us with an expanded set of excellent students essays each of which addresses an important national security policy issue. It is an important part of the Baker Center’s mission to engage UTK students in the political and public policy process, and I applaud our student authors fortheir contributions to this symposium. I hope you find this issue of the Baker Center Journal for Applied Public Policy to be both interesting and thought-provoking and that it will encourage you to participate in America’s unique and wonderful political and policy processes
