In this casuistry, two accidents from Germany and Switzerland are presented that happened during the shot of recoilless anti-tank weapons. In both cases, the injuries led to the death of two soldiers: A 22-year-old soldier in Germany was struck by the counter mass of a so-called Davis gun which had been fired by a comrade during a firing exercise; he died from his severe injuries, especially in the abdominal part of the body. As a peculiarity of the wound morphology, it was found to be a thick-layered, metallic, gray material in the wound cavity, which corresponded to the material of the counter mass that was ejected opposite to the shooting direction. The other case took place in Switzerland, where a 24-year-old soldier was seriously injured during an exercise with portable anti-tank rockets. At the time the shot was fired, he stood behind the launcher and was hit by the propulsion jet of the rocket motor. He died as well from his severe injuries, which were located at the chest done by the gas jet and by the very high pressure. In both cases, two different causes of death were present: massive blunt violence in the first case versus a jet of hot gases of very high speed and temperature in the second case.

The purpose of our study was to examine Positive Behavior Interventions and Supports (PBIS) implementation fidelity and student outcomes for secondary schools in a large, urban school district placed under a corrective action plan due to disproportionate suspension practices for students of color. Drawing upon data over a four-year period on PBIS implementation fidelity, discipline referrals, suspensions, and standardized test scores, we employed repeated measures analysis of variance (ANOVA) and revealed improved outcomes in the first year, but improvements did not continue over time. Additionally, academic outcomes did not show any significant increases. The study concludes with implications for policy, practice, and future research.

The purpose of this study was to examine Positive Behavior Interventions and Supports (PBIS) implementation fidelity and student outcomes for secondary schools in a large, urban school district. The state department of education placed the district under corrective action due to disproportionate suspension practices. In response to the corrective action, district administration required 24 schools to participate in PBIS training. This study is an analysis of PBIS implementation fidelity data, discipline referrals, suspensions, and standardized test scores to determine if there were significant differences after PBIS implementation. I employed the repeated measures analysis of variance (ANOVA) to examine outcomes over a four-year period. Results indicated increased PBIS implementation fidelity over time. Discipline outcomes showed improvement in one year included in the study, but improved outcomes did not sustain over time. Additionally, academic outcomes did not show any significant increases. I conclude by discussing the results in terms of helping urban schools improve outcomes for students. vii TABLE OF CONTENTS
