A Talk With Time, Samanatha Kuban

Master's Theses

I chose to write a collection of genre-mixing short stories to depict the vastness and complexity of time as my English Master’s thesis project. Thinking about the constructs of time and how they function or do not function within our society sparked my interest in this field of knowledge and discussion. I am a person that tends to feel a large amount of anxiety surrounding the passage of time or time limits so reading deeper into studies of time and how we think about it in various ways proved to be an outlet for a better understanding. I chose to …

Common Law Statutes, Charles W. Tyler

Notre Dame Law Review

The defining feature of a “common law statute” is that it resists standard methods of statutory interpretation. The category includes such important federal statutes as the Sherman Act, § 1983, and the Labor Management Relations Act, among others. Despite the manifest significance of common law statutes, existing caselaw and legal scholarship lack a minimally defensible account of how courts should decide cases arising under them. This Article supplies such an account. It argues that judges should decide cases arising under common law statutes by applying rules representing a consensus among American courts today—i.e., rules that jurisdictions generally have in common. …

The Broadwater Formation (Pliocene) Of Nebraska And Southeastern Wyoming, Robert F. Diffendal Jr., James B. Swinehart

Robert F. Diffendal, Jr., Publications

The Broadwater Formation, initially defined in 1945, is a Pliocene-aged coarse-grained alluvial deposit in Nebraska and southeastern Wyoming. It is characterized by a complex stratigraphic history and debated geologic interpretations. The formation is a rich resource of groundwater for the citizens of Nebraska and the Central Great Plains. We aim to synthesize and redefine the Broadwater Formation, shedding light on its distribution, geological characteristics, and paleoenvironmental significance. While historical hypotheses on Broadwater Formation paleovalley trajectories suggested northwest-southeast trending valleys, later investigations proposed wind-driven erosional patterns to explain the unique topographic features observed. The Broadwater is divided into an unnamed Upper …

Teachers' Perceptions Of The Effectiveness Of Culturally Responsive Practices, Kimberly M. Burks

Dissertations (2016-Present)

Over the years, research regarding racial disproportionalities in the assignment of disciplinary consequences has been evaluated. Evaluation of the ever-increasing Black-White achievement gap has been at the forefront of educational research for decades. Gaining a better understanding of why this gap persists not only benefits schools but students as well. By enforcing certain policies, Black students are frequently removed from the educational environment due to subjective disciplinary infractions and perceived negative behaviors. Negative stereotypes often perpetuate teacher perceptions and expectations; as a result, minority students, especially Black students, are at the receiving end of those lowered expectations. Teachers must understand …
