National mandates to decrease suspension numbers have prompted school districts across the country to turn to a practice known as restorative justice as an alternative to removing students through suspension or referral to law enforcement for problematic behavior. This ethnographic case study examines school-based restorative justice programs as potentially disruptive social movements in dismantling the school-to-prison-pipeline through participatory analysis of one school’s implementation of Discipline that Restores.

Findings go beyond suspension numbers to discuss the promise inherent in the program’s validation of student lived experience using a disruptive framework within the greater context of the politics of care and the school-to-prison-pipeline. Findings analyze the intersection of race, power, and identity with the experience of care in defining community to illustrate some of the prominent structural impediments that continue to work to cap the program’s disruptive potential. This study argues that restorative justice, through the experience of care, has the potential to act as a disruptive force, but wrestles with the enormity of the larger structural investments required for authentic transformative and disruptive change to occur.

As the restorative justice movement gains steam, on-going critical analysis against a disruptive framework becomes necessary to ensure the future success of restorative discipline in disrupting the school-to-prison-pipeline.

The SAE Baja series is a competition that challenges university student teams on all aspects of designing, building, and testing an all-terrain vehicle. In the competition, the teams present their engineering analysis of all components of their vehicle to a panel of professional engineers to show why the team's design is the overall best in performance and in manufacturing cost. Currently Arizona State University's SAE Baja team does not have a method to analyze their vehicle's suspension system, especially on the car's shock absorbers. The current solution to this problem is to change the shock absorber parameters, test drive the car, and repeat the shock absorber tuning until the car is able to produce the performance that the team desires. The following paper introduces and demonstrates three different methods, ADAMS Car, SOLIDWORKS, and MATLAB, that can be used to analyze the suspension system and gather data that can be used in the competition presentation. ADAMS Car is a power software that is used in the automotive and other engineering fields. The program does have a steep learning curve, but once the team is comfortable using it, ADAMS is very helpful with subsystem analysis and full body analysis. SOLIDWORKS can be used to perform motion analysis and drop tests, which can then be exported into ADAMS for further analysis. MATLAB can be used to model the Baja vehicle as a quarter model, which makes it easier for the team to model. Using the methods presented in this paper, ASU's Baja team can test coil-over and air shock absorbers to determine which type is more suitable for the performance and overall cost of the whole vehicle.

Motorcycles must be designed for safety and long operation. Front suspension systems must in turn be safe and able to operate for long service lives. Challenges to achieving safe and long service lifetimes include designing components (rims, axles, forks, etc.) to withstand various loading conditions not just once but numerous times as a matter of fatigue life. An already developed CAD model of a motorcycle suspension was taken and optimized for various loading conditions. These conditions included static loading, braking, cornering, and wheelie and front impact loads. In all cases, front impact load was the critical loading condition when FEA in SolidWorks Simulation was conducted for the components. All components were then optimized to handle the impact load by changing geometry until safety factors of 4.0 ± 0.25 were achieved. Components were then analyzed for fatigue life, with all steel and magnesium components having infinite predicted fatigue lives and all aluminum components having fatigue lives predicted with corrected S-N curves created for up to 500 million loading cycles. The design was optimized with all components becoming improved for stress compliance, with room for improvement existing in both defining loads for analysis and developing more accurate and rigorous fatigue life models.
