Milwaukee Domestic Violence Experiment Data on Arrest Procedures, 1987-1989

From April 1987 to August 1988, data were collected for the Milwaukee Domestic Violence Experiment to examine how suspects' perceptions of procedural fairness affected subsequent violence. The experiment randomly assigned misdemeanor domestic battery cases to one of three conditions: a warning with no arrest, a brief arrest, or a longer arrest. Variables include demographic and background information, as well as descriptive variables pertaining to the domestic violence incident.

Temperature Impact on AMPS and AHPS Polymer Performance in Oil Well Cement

Two synthetic polymers were tested for temperature stability between 100 and 220°C under 35 bar pressure, simulating oil well cementing conditions. The study, authored by Constantin Tiemeyer of the Technical University of Munich, assessed fluid loss performance via high-pressure filtration tests and polymer conformation via dynamic light scattering. The AMPS-based polymer showed reduced performance due to chain shrinkage, while the AHPS-based additive maintained stable fluid loss control.
