An Examination of Adult Bullying in the K-12 Workplace: Implications for School Leaders

The issue of bullying in K-12 schools usually brings images of students to mind, but a recent quantitative study of a sample from K-12 school personnel in Michigan showed that 27.8% of adults in the K-12 workplace consider themselves the target of an adult bully. This study calls for school leadership to recognize and proactively address the issue of workplace bullying in K-12 schools through policy, procedures, training, prevention, enforcement, and positive resolution to provide a safe, non-threatening environment in which to work and learn

Visualizing Sensor Network Coverage with Location Uncertainty

We present an interactive visualization system for exploring the coverage in sensor networks with uncertain sensor locations. We consider a simple case of uncertainty where the location of each sensor is confined to a discrete number of points sampled uniformly at random from a region with a fixed radius. Employing techniques from topological data analysis, we model and visualize network coverage by quantifying the uncertainty defined on its simplicial complex representations. We demonstrate the capabilities and effectiveness of our tool via the exploration of randomly distributed sensor networks
