Faculty Research, Scholarly, and Creative Activity

The Western Indian Ocean (WIO) is known for its high diversity of chondrichthyans (sharks, rays, and chimaeras). However, intense fishing pressure has led to severe population declines and local extinctions of several species. The Important Shark and Ray Area (ISRA) process is a collaborative, evidence-based approach used to identify critical habitat for chondrichthyans. We analysed ISRAs across the WIO to quantify the diversity of research methods used to identify them, evaluate spatial overlap with designated marine protected areas (MPAs), model the influence of several species- and jurisdiction-specific variables on ISRA delineation, and explore the importance of incorporating unpublished data into …

Existence Of Traveling Waves Of Lotka Volterra Type Models With Delayed Diffusion Term And Partial Quasimonotonicity, William Barker

Faculty Scholarship

This paper investigates the existence of traveling wave solutions for diffusive two-species Lotka–Volterra systems with delays in both the reaction and diffusion terms under partial monotonicity assumptions. The model incorporates small-memory effects in the homo- geneous diffusion term, representing a modification of the random-walk interpretation underlying Fick’s law. We extend the partial (cross) monotone iteration method to systems satisfying a partial quasi-monotone condition through the construction of appropriate upper and lower solutions. Convergence of the iteration is established using Schauder’s fixed point theorem.

Ethics Of Artificial Intelligence For Lawyers: Shall We Play A Game? The Rise Of Artificial Intelligence And The First Cases, Cliff Mckinney

Arkansas Law Notes

In the 1983 movie WarGames, a young computer hacker accidentally accesses a United States military supercomputer programmed to run nuclear war simulations.

Perception As Beholding: Theological Possibility And Moral Implication Of Merleau-Ponty's Notion Of Embodied Subject, Erickson L. Totanes

Budhi: A Journal of Ideas and Culture

In this article, I argue that Merleau -Ponty’s concept of perception reveals a way of seeing where the subject is involved with the object in a dynamic, reversible, and expanding relationship. This notion challenges the traditional and Cartesian subject -object dichotomy by emphasizing the embodied and lived experience of perception which elicits a process, a way of looking, anticipating, and reflexively, a way of being itself. By aligning seeing with beholding, I attempt to show how as simple an act as seein g evokes a manner of being related to an object, other people, and the world. The emergence of …
