This report provides the results for the 2015 Workplace and Gender Relations Survey of Reserve Component Members (2015WGRR). The overall purpose of the 2015 WGRR is to document the extent to which Reserve component members reported experiencing sexual assault in the 12 months prior to filling out the survey, the details surrounding those events, bystander intervention, and the members' perceptions of the effectiveness of sexual assault policies, training, and programs.

This report describes the statistical methodologies for the 2015 Workplace and Gender Relations Survey of Reserve Component Members (2015 WGRR). The first section describes the sample design and selection of the sample. The second section describes weighting and variance estimation, as well as a comparison to the 2014 RAND Military Workplace Study. The third section describes the statistical tests used for the 2015 WGRR. The fourth section describes the calculation of location, completion, and response rates for the full sample and population subgroups. The final section contains the nonresponse bias (NRB) analysis.

NSRDC was tasked by the U.S. Coast Guard to analyze hull springing stresses of two Great Lakes ore ships for a two year period of operation. The maximum and RMS springing stress, wave bending stress, and unfiltered stress were found for each 30 minute recording interval. In addition to the normal recording intervals, some runs were taken at various headings with respect to the sea and simultaneously with wave buoy data. The natural frequencies and deflection profiles of the BEEGHLY hull were calculated and compared with some available stress data. Quartering or following sea effects are compared with effects of head to beam seas. A procedure was developed to predict the stresses on the basis of calculated wave bending stresses. The distributions of peaks of the wave bending, springing, and unfiltered stresses are given. A procedure was developed to estimate fatigue life accounting for the complexities of the stress signal.
