Max Chart: Combining X-bar Chart and S Chart

Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...

The E¤ect of Migration on NativesEmployment Outcomes: Evidence from the Fall of the Berlin Wall

I study the impact of East-West internal migration in Germany after the fall of the Berlin Wall on wages and unemployment rates in West German local labor markets. Because migrants’ choice of destination is likely to be correlated with local labor market conditions, I instrument migration ‡ows into each western labor market with the distance to each of the East German regions sending migrants a...

E ect of Concave Wall Geometry on Heat Transfer in Hypersonic Boundary Layers

Heat transfer measurements are made to investigate the e ects of concave surface curvature on a high-stagnation enthalpy boundary layer in a Mach 5.1 ow. Experiments are carried out using two curved models with 16 and 25 degree turning angles, and baseline planar models ( at plate and linear ramp) for comparative study. Streamwise and spanwise cross-sections are obtained. Signi cant destabiliza...

The sham ECT literature: implications for consent to ECT.

The author reviewed the placebo-controlled literature on electroconvulsive therapy (ECT) for depression. No study demonstrated a significant difference between real and placebo (sham) ECT at 1 month posttreatment. Many studies failed to find a difference between real and sham ECT even during the period of treatment. Claims in textbooks and review articles that ECT is effective are not consisten...
