Prefatory Remark

I am honored to have been invited to offer some brief remarks on the problems and challenges confronting American legal education. As a lawyer and legislator, I have seen both the strengths and weaknesses of our legal system, and I believe that some changes may well be in order if we are to address successfully the challenges that lie ahead

Reducing Greenhouse Gas Emissions From U.S. Transportation

Outlines the need to cut transportation emissions to limit climate change effects, mitigation options and technologies, policies to promote mitigation, and various scenarios for public attitudes, public policy, technological progress, and energy prices

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

What the ‘Moonwalk’ Illusion Reveals about the Perception of Relative Depth from Motion

When one visual object moves behind another, the object farther from the viewer is progressively occluded and/or disoccluded by the nearer object. For nearly half a century, this dynamic occlusion cue has beenthought to be sufficient by itself for determining the relative depth of the two objects. This view is consistent with the self-evident geometric fact that the surface undergoing dynamic occlusion is always farther from the viewer than the occluding surface. Here we use a contextual manipulation ofa previously known motion illusion, which we refer to as the‘Moonwalk’ illusion, to demonstrate that the visual system cannot determine relative depth from dynamic occlusion alone. Indeed, in the Moonwalk illusion, human observers perceive a relative depth contrary to the dynamic occlusion cue. However, the perception of the expected relative depth is restored by contextual manipulations unrelated to dynamic occlusion. On the other hand, we show that an Ideal Observer can determine using dynamic occlusion alone in the same Moonwalk stimuli, indicating that the dynamic occlusion cue is, in principle, sufficient for determining relative depth. Our results indicate that in order to correctly perceive relative depth from dynamic occlusion, the human brain, unlike the Ideal Observer, needs additionalsegmentation information that delineate the occluder from the occluded object. Thus, neural mechanisms of object segmentation must, in addition to motion mechanisms that extract information about relative depth, play a crucial role in the perception of relative depth from motion

Signatures of the slow solar wind streams from active regions in the inner corona

Some of local sources of the slow solar wind can be associated with spectroscopically detected plasma outflows at edges of active regions accompanied with specific signatures in the inner corona. The EUV telescopes (e.g. SPIRIT/CORONAS-F, TESIS/CORONAS-Photon and SWAP/PROBA2) sometimes observed extended ray-like structures seen at the limb above active regions in 1MK iron emission lines and described as "coronal rays". To verify the relationship between coronal rays and plasma outflows, we analyze an isolated active region (AR) adjacent to small coronal hole (CH) observed by different EUV instruments in the end of July - beginning of August 2009. On August 1 EIS revealed in the AR two compact outflows with the Doppler velocities V =10-30 km/s accompanied with fan loops diverging from their regions. At the limb the ARCH interface region produced coronal rays observed by EUVI/STEREO-A on July 31 as well as by TESIS on August 7. The rays were co-aligned with open magnetic field lines expanded to the streamer stalks. Using the DEM analysis, it was found that the fan loops diverged from the outflow regions had the dominant temperature of ~1 MK, which is similar to that of the outgoing plasma streams. Parameters of the solar wind measured by STEREO-B, ACE, WIND, STEREO-A were conformed with identification of the ARCH as a source region at the Wang-Sheeley-Arge map of derived coronal holes for CR 2086. The results of the study support the suggestion that coronal rays can represent signatures of outflows from ARs propagating in the inner corona along open field lines into the heliosphere.Comment: Accepted for publication in Solar Physics; 31 Pages; 13 Figure

Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS

Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations
