Getting What You Pay For: The Debate Over Equity in Public School Expenditures

This article, created by Deborah Lynn Guber of the University of Vermont, addresses a dataset on public school expenditures and SAT performance. The data comes from a 1997 study conducted by the "Digest of Education Statistics." The lesson talks about graphical interpretations of data, omitted variables and misleading statistics. The author states that the "exercise is ideally suited for classroom discussion in elementary statistics or a research methods course.&quot

The very forward CASTOR calorimeter of the CMS experiment

International audienceThe physics motivation, detector design, triggers, calibration, alignment, simulation, and overall performance of the very forward CASTOR calorimeter of the CMS experiment are reviewed. The CASTOR Cherenkov sampling calorimeter is located very close to the LHC beam line, at a radial distance of about 1 cm from the beam pipe, and at 14.4 m from the CMS interaction point, covering the pseudorapidity range of $-$6.6 $\lt\eta\lt$ $-$5.2. It was designed to withstand high ambient radiation and strong magnetic fields. The performance of the detector in measurements of forward energy density, jets, and processes characterized by rapidity gaps, is reviewed using data collected in proton and nuclear collisions at the LHC
