Introduction: Current cognitive assessments suffer from floor/ceiling and practice effects, poor psychometric performance in mild cases, and repeated assessment effects. This study explores the use of digital speech analysis as an alternative tool for determining cognitive impairment. The study specifically focuses on identifying the digital speech biomarkers associated with cognitive impairment and its severity.

Methods: We recruited older adults with varying cognitive health. Their speech data, recorded via a wearable microphone during the reading aloud of a standard passage, were processed to derive digital biomarkers such as timing, pitch, and loudness. Cohen's d effect size highlighted group differences, and correlations …

The Tangled Webs We Weave: Examining The Effects Of Ceo Deception On Analyst Recommendations, Steven J. Hyde, Eric Bachura, Jonathan Bundy, Richard T. Gretz, Wm. Gerard Sanders

Boise State University Publications and Presentations

Research Summary

Organizations are punished by analysts and investors when material deceit by their CEO is uncovered. However, few studies examine analysts' responses to deceptive CEOs before their deceit is publicly known. We use machine learning (ML) models to operationalize the likelihood of CEO deception as well as analysts' suspicion of CEO deception on earnings calls. Controlling for analysts' suspicion of deception, we show that analysts are prone to assigning superior recommendations to deceptive CEOs, particularly those deemed as All-Star analysts. We find that the benefits of CEO deception are lower for habitual deceivers, pointing to diminishing returns of deception. …

The Major Questions Doctrine At The Boundaries Of Interpretive Law, Daniel E. Walters

Faculty Scholarship

The Supreme Court’s apparent transformation of the major questions doctrine into a clear statement rule demanding clear congressional authorization for “major” agency actions has already had, and will continue to have, wide-ranging impacts on American public law. Not the least of these is the impact it will have on the enterprise of statutory interpretation. Indeed, while it is easy to focus on the policy repercussions of a newly constrained Congress and newly hamstrung administrative state, this Article argues that equally important is the novel precedent that is set in this particular formulation of a clear statement rule, which stands almost …

“The Freedom To Teach”: The Role Of (Re)Professionalization In Cultivating Responsive Schooling For Immigrant Students, Adriana Villavicencio, Sarah Klevan, Chandler Patton Miranda, Reva Jaffe-Walter, Hua Sebastian Cherng

Department of Educational Foundations Scholarship and Creative Works

While we know that professionalization improves outcomes for teachers, education policy has effectively deprofessionalized teachers, especially those who serve immigrant English Learners. Based on a three-year case study, this paper explores how teachers in an immigrant-serving school exercised autonomy and authority over their instruction and professional development. Drawing on staff interviews and observations of teacher meetings, this paper further describes how these professional conditions positioned teachers to better serve their student population. Our study also revealed the underlying conditions that made teacher autonomy possible, including the negotiation of external policy and a robust model of shared decision-making. By providing rich …

“Legally Magic” Words: An Empirical Study Of The Accessibility Of Fifth Amendment Rights, Kate Weisburd, Roseanna Sommers

Faculty Scholarship

Fifth Amendment case law (including Miranda v. Arizona) requires that individuals assert their right to counsel or silence using “explicit,” “clear,” and “unambiguous” statements—or, as some dissenting judges have lamented, using “legally magic” words. Through a survey of 1,718 members of the U.S. public, we investigate what ordinary people believe it takes to assert the right to counsel and the right to silence. We then compare their perceptions against prevailing legal standards governing invocation.

With respect to the right to counsel, the survey results indicate that members of the public have a uniformly lower threshold for invocation than do courts. …
