Policing By Proxy: Interrogating Big Tech's Role In Law Enforcement, Claire Elizabeth
Policing By Proxy: Interrogating Big Tech's Role In Law Enforcement, Claire Elizabeth
University Honors Theses
Predictive policing, sometimes referred to as data-driven or actuarial policing, is a method of policing that uses a risk-based approach to law enforcement. For-profit technology companies market proprietary risk assessment algorithms to law enforcement organizations as tools meant to proactively mitigate crime. Using data collected from a vast array of sources, both personal and public, police are able to "predict" the likelihood of criminal activity in a given area using these algorithms. Proponents claim that risk assessment tools have the potential to fight crime with unbiased accuracy and speed by predicting when, where, and whom to police by relying on …
Minimality Of Integer Bar Visibility Graphs, Emily Dehoff
Minimality Of Integer Bar Visibility Graphs, Emily Dehoff
University Honors Theses
A visibility representation is an association between the set of vertices in a graph and a set of objects in the plane such that two objects have an unobstructed, positive-width line of sight between them if and only if their two associated vertices are adjacent. In this paper, we focus on integer bar visibility graphs (IBVGs), which use horizontal line segments with integer endpoints to represent the vertices of a given graph. We present results on the exact widths of IBVGs of paths, cycles, and stars, and lower bounds on trees and general graphs. In our main results, we find …
