Based on findings of previous studies, there was speculation that two well-known experimental design software packages, JMP and Design Expert, produced varying power outputs given the same design and user inputs. For context and scope, another popular experimental design software package, Minitab® Statistical Software version 17, was added to the comparison. The study compared multiple test cases run on the three software packages with a focus on 2k and 3K factorial design and adjusting the standard deviation effect size, number of categorical factors, levels, number of factors, and replicates. All six cases were run on all three programs and were attempted to be run at one, two, and three replicates each. There was an issue at the one replicate stage, however—Minitab does not allow for only one replicate full factorial designs and Design Expert will not provide power outputs for only one replicate unless there are three or more factors. From the analysis of these results, it was concluded that the differences between JMP 13 and Design Expert 10 were well within the margin of error and likely caused by rounding. The differences between JMP 13, Design Expert 10, and Minitab 17 on the other hand indicated a fundamental difference in the way Minitab addressed power calculation compared to the latest versions of JMP and Design Expert. This was found to be likely a cause of Minitab’s dummy variable coding as its default instead of the orthogonal coding default of the other two. Although dummy variable and orthogonal coding for factorial designs do not show a difference in results, the methods affect the overall power calculations. All three programs can be adjusted to use either method of coding, but the exact instructions for how are difficult to find and thus a follow-up guide on changing the coding for factorial variables would improve this issue.

Police use of force is a controversial practice on both the political stage and by scholars of criminal justice. Scholarly research has highlighted best practice for police departments’ use of force policies. Diverging from these policies may produce ineffective and harmful use of force practices within departments. Because of these potential consequences of police departments diverging from research-based evidence, it is necessary to identify when recommended policy is not being utilized. The purpose of this study is to identify whether there are points of dissent or congruence between criminal justice scholars and police departments with regards to use of force policy. Efforts have been made to empirically identify best practices of use of force policy. The findings of this study indicate that points of dissent do exist in the policies of police departments in the U.S. and the policy recommendations of criminal justice scholars. The implications of these findings include reform to the use of force policies of police departments to more accurately reflect the policies recommended by scholars in the use of force.

COVID-19 has been challenging for nearly everyone in different ways. Healthcare organizations have had to quickly change policy, modify operations, reorganize facilities, hire, and train staff to overcome COVID-19 related challenges to be able to still provide care for patients, all while being mindful of the protection of their staff. Some healthcare organizations have responded particularly well, perhaps due to preparedness, planning, or exceptional leadership in times of crisis. To explore this, we invited seven healthcare system leaders from three different organizations in Arizona to talk about how they overcame challenges at the beginning of this pandemic with effective strategies and any leadership tips they had for the future. After the interviews were conducted, the interviews were transcribed, coded qualitatively, and separated into themes and categories to analyze their answers to the questions asked. The results and conclusions included strategies such as having open and honest communication, teamwork, rapidly developing communicating policies, and widely adopting new work practices like Telemedicine, Zoom, and working at home as crucial. This report is designed to assist in aiding and inspiring future or other leaders to be better prepared for solving various challenges with other emergencies that arise in the future.
