    The Influence of the Pennsylvania Mainline of Public Works

    Full text link
    The Pennsylvania Mainline of Public Works, authorized and begun by Governor John Andrew Schulze in 1826, was the main transportation artery across Pennsylvania from the beginning of its operations in 1828 until the Pennsylvania Railroad purchased it in 1857. Though it was only in service for about thirty years, the Mainline was instrumental in shaping and affecting individuals, both passengers and employees of the canal; as well as Pennsylvania towns such as Saltsburg, Alexandria, Pittsburgh, and Philadelphia. This in turn affected national commerce

    This issue brief explores five aspects of gun violence in Pennsylvania that are especially alarming, unusual, or above the national average:1. Pennsylvania's rate of gun homicides is among the highest in the nation, particularly in communities of color.2. Pennsylvania law enforcement officers are killed with guns at an exceptionally high rate.3. More Pennsylvanians are killed by gun violence than in car accidents annually.4. Pennsylvania is a top supplier of crime guns recovered in other states.5. Pennsylvania women are killed with guns wielded by intimate partners at a high rate

    A VIEW FROM THE GROUND: A REFORM GROUP’S PERSPECTIVE ON THE ONGOING EFFORT TO ACHIEVE MERIT SELECTION OF JUDGES

    Get PDF
    This article describes the history of judicial selection in the state of Pennsylvania. It describes the judicial selection reform movement and the growth of the organization Pennsylvanians for Modern Courts ( PMC ) which devises solutions to meet the various challenges to judicial integrity in Pennsylvania. It focuses on the merit system that PMC has been trying to achieve for Pennsylvania\u27s appellate courts

    Double Checking the Doctor’s Credentials: The New Medical Expert Qualification Statute of MCARE

    Get PDF
    The problem of rapidly escalating premiums paid by doctors for medical malpractice insurance has plagued Pennsylvania in the last decade. These rates have uprooted Pennsylvania doctors from their local practices and hospitals in favor of out-of-state locations with lower rates. Furthermore, some Pennsylvania doctors and hospitals specializing in high-risk procedures have refused to perform high-risk surgeries or have limited their practice to more routine procedures

    Precision Measurements of the Top Quark Mass at the Tevatron

    Get PDF
    We report precision measurements of the top quark mass using events collected by the D{\O}and CDF II detectors from ppˉp\bar{p} collisions at s=1.96\sqrt s = 1.96 TeV at the Fermilab Tevatron. Measurements are presented in multiple decay channels. In addition, we present a combination of the most precise measurements in each channel to date: Mtop=172.5±1.3stat±1.9systGeV/c2 M_{top} = 172.5 \pm 1.3_{stat} \pm 1.9_{syst} {\textrm GeV}/c^2 Precision Measurements of the Top Quark Mass at the TevatronComment: 4 pages, 7 figure

    MEASURING THE PRIMARY IMPACTS OF SEVERANCE TAXATION: A SPATIAL EQUILIBRIUM APPROACH

    Get PDF
    A spatial equilibrium model is used to quantify the effects of a severance tax on the Pennsylvania coal market. Two regions are identified: the Pennsylvania Market Area and an import/export region. The impacts on prices and quantities of coal supplied and demanded are found to be small. Little of the tax is exported from Pennsylvania, with a high proportion of the tax being passed back to Pennsylvania coal producers. Although the tax revenue exceeds the welfare losses in Pennsylvania, this result is very sensitive to the magnitude of the Pennsylvania own-price demand elasticity.Public Economics,

    Progress in Top Quark Physics

    Full text link
    Experimental measurements of the properties of the top quark have improved and will continue to improve significantly, with the excellent operation of the CDF and D0 experiments and the Tevatron ppˉp\bar{p} collider at the Fermi National Accelerator Laboratory. All of the final state experimental signatures from top quark production and decay are being analysed to test if this most massive quark is sensitive to new physics beyond the standard model. So far, observations are consistent with the standard model. New techniques have dramatically improved the precision of the top quark mass measurement to 1.7% and set the stage for a sub-1% measurement by 2008. This improved knowledge of the top quark mass sharpens the standard model prediction for the mass of the undiscovered Higgs boson, with implications for Higgs studies at the future LHC and ILC.Comment: 11 pages.
