Veterans In Focus: Disability And Veterans In Rural America, Hannah W. Pepprock, Lillie Greiman, University Of Montana Rural Institute

Health and Wellness

There are an estimated 17 million Veterans living throughout the United States. Relative to the general population, Veterans are more likely to experience disability. Veterans are also disproportionately represented in rural areas across the U.S. As people with disabilities are also disproportionately represented in rural areas, it is valuable to explore the intersection between veteran status, disability, and rurality. This analysis uses publicly available date from the American Community Survey to examine service-connected disability rating status and the ACS-6 questions on functional ability as they related to U.S. regions and rurality.

Quantum & Classical Machine Learning Studies Of Semiconductor Crystal Epitaxy, Andrew S. Messecar, Steven M. Durbin, Robert A. Makin

Waldo Library Student Exhibits

Molecular beam epitaxy (MBE) is an ultra–high vacuum crystal growth technique for the synthesis of high–purity materials. MBE allows for controlled deposition to the precision of a single atomic layer.

Understanding the optimal synthesis conditions for MBE can enhance experiment design and accelerate the discovery of new materials.

In this study, we apply materials informatics – investigating the utility of both quantum and conventional machine learning algorithms – to a decade’s worth of plasma–assisted MBE (PAMBE) data of GaN and InN.

Amazon’S Algorithmic Rents: The Economics Of Information On Amazon, Ilan Strauss, Tim O’Reilly, Mariana Mazzucato

UC Law Science and Technology Journal

Amazon’s maturing e-commerce platform has seen its business strategy evolve from growth at any cost to a “quest for profit”, underpinned by its burgeoning $37.7bn advertising business. Through advertising, Amazon compels its captive third-party merchant ecosystem to pay for one of its most valuable assets – customer attention. Advertising leverages Amazon’s unique position as a discovery platform. Discovery is governed by Amazon’s algorithms — the nerve centre of its conduct and a critical guide to market structure. Algorithms are the principal market institution coordinating exchange online, yet often escape market investigations.

Prevailing doctrine assumes that platform rent extraction, via algorithmic …
