    This presentation investigates the similarities and differences between the asylum policies and the treatment of detainees who crossed the U.S.-Mexico border during the Obama administration versus during the Trump administration. This presentation asserts that while both Obama’s and Trump’s policies toward asylum seekers were very similar in being strict and harsh, Trump’s abrasive rhetoric and more extreme stances established distinct differences between the two administrations. In particular, this presentation explores conditions inside the detention facilities under each president, Trump’s Zero Tolerance Policy in relation to Obama’s policies, Trump’s use of Title 42, and each president externalizing the U.S. border. Although Obama detained families and many unaccompanied minors upon crossing the border in temporary facilities, Trump took this a step further by separating children from their parents under his Zero-Tolerance policy for deterrence. In addition, using the justification of the COVID-19 pandemic health concerns, Trump nearly dismantled any semblance of due process for asylum seekers by evoking Title 42. Title 42 provides border authorities with unilateral authority to expel migrants who do not have prior permission to enter the country without offering asylum. Both presidents had the policy of the externalized U.S. border, the practice of making it harder for asylum seekers to reach U.S. soil in the first place. Reporters touring the detention facilities, news articles demonstrating public opinion, White House website archives, government documents, political speeches, first-hand accounts of the asylum system, and analytical scholarly articles provide important insight in piecing together the asylum records of the Obama and the Trump administrations. It is critical to understand the continuities and changes between the Obama and Trump administrations’ asylum policies and treatment of detainees to make better, more humane, and more informed policy decisions in the future regarding those seeking asylum.https://orb.binghamton.edu/research_days_posters_2021/1094/thumbnail.jp

    Neutrino Emission from Superfluid Neutron-Star Cores: Various Types of Neutron Pairing

    Full text link
    We calculate and provide analytic fits of the factors which describe the reduction of the neutrino emissivity of modified Urca and nucleon-nucleon bremsstrahlung processes by superfluidity of neutrons and protons in neutron-star cores. We consider 1^1S0_0 pairing of protons and either 1^1S0_0 or 3^3P2_2 pairing of neutrons. We analyze two types of 3^3P2_2 pairing: the familiar pairing with zero projection of the total angular momentum of neutron pairs onto quantization axis, mJ=0m_J=0; and the pairing with ‚ą£mJ‚ą£=2|m_J|=2 which leads to the gap with nodes at the neutron Fermi surface. Combining the new data with those available in the literature we fully describe neutrino emission by nucleons from neutron star cores to be used in simulations of cooling of superfluid neutron stars.Comment: 14 pages, 6 figures, A&A, accepte

    Interpretation of Ultrasonic Scattering Measurements by Various Flaws from Theoretical Studies

    Let me begin by saying that this is part of a program which is very much complementary to and is helped by the experimental program; so I\u27ll repeat, in part, some of the overview comments that Bruce Thompson made this morning. We\u27ve regarded our role as one of trying to plug into the overall program those aspects of the theory of elastic wave scattering which can be developed in a utilitarian way in terms of modern analytical and computational techniques, in a form which I hope can be useful in signal processing, interpretation, design of experiment, etc. To outline our point of view, I\u27m going to first give a survey of what we have been doing and then give some of the results. It\u27s rather shocking to think of the amount of money that goes into an experimental program and its interpretation, if the interpretation is done in terms of acoustic or scalar wave scattering theories, when the differences from proper elastic theory can be as great as those which Bruce Thompson pointed to this morning
