A Reanalysis Of Population Dynamics In The Casas Grandes Region Of Northern Mexico Using Mitochondrial Dna, Meradeth Snow, Michael T. Searcy

Faculty Publications

The Casas Grades region in northwest Chihuahua, Mexico, is ideally situated to explore the notion of contact between the Southwest/Northwest and Mesoamerica, as it lies geographically in the borderlands where traditions of both culture areas were practiced. In order to explain these ties, past researchers have suggested the flourishing Casas Grandes population in the thirteenth century AD was caused by migrants from Mesoamerica, as first suggested by Di Peso in his pochteca hypothesis. Others, such as Lekson and his Chaco Meridian hypothesis, suggest migration from the north. Mitochondrial genetic data from earlier and later time periods provides the ability to …

Signals From On High And The Power Of Growth Mindset: A Natural Field Experiment In Attracting Minorities To High-Profile Position, Jeffrey A. Flory, Andreas Leibbrandt, Christina Rott, Olga B. Stoddard

Faculty Publications

We conduct a large-scale natural field experiment with a Fortune 500 company to test several approaches to attract minorities to high-profile positions. 5,000 prospective applicants were randomized into treatments varying a portion of recruiting materials. We find that self-selection at two early-career stages exhibits a substantial race gap. Importantly, we show that this gap can be strongly influenced by several treatments, with some increasing application rates by minorities by 40 percent and others being particularly effective for minority women. The heterogeneities we find by gender, race, and career stage shed light on the underlying drivers of self-selection barriers among minorities.

Making “Habitat Quality” Meaningful: Quantifying Demographic Effects Of Habitat In Two Sympatric Species, Anna Katherine Moeller

Graduate Student Theses, Dissertations, & Professional Papers

Habitat quality may be an underlying factor driving or exacerbating mule deer (Odocoileus hemionus) population declines across their range and concurrent white-tailed deer (Odocoileus virginianus) population increases. A clearer understanding of how the two species respond to habitat variables is needed to disentangle the drivers of mule deer decline and identify opportunities to change population trajectories through habitat management. Capitalizing on extensive monitoring data for sympatric populations of mule deer and white-tailed deer, this dissertation improves understanding of habitat quality by exploring and developing modeling approaches that connect habitat and demographics in these two species.

Using a resource selection function …

Genetic Monitoring And Rescue In Mid-Atlantic Brook Trout (Salvelinus Fontinalis) Poulations, Zachary Lorn Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Brook trout (Salvelinus fontinalis) populations have experienced dramatic declines throughout their native range, in part, due to anthropogenic land use and habitat fragmentation. In the mid-Atlantic region, brook trout populations often occupy small, headwater habitat fragments in demographic and genetic isolation, making them vulnerable to inbreeding and genetic drift. My dissertation evaluates different methods for genetic assessment, monitoring, and management of small, isolated brook trout populations. First, I examined the potential value of effective number of breeders (N_b) estimates for genetic monitoring by determining whether N_b estimates were sensitive to habitat characteristics known to affect …

Bacteriophage Infection Induces Intracellular Polyamine Accumulation As A Defense Mechanism In Pseudomonas Aeruginosa, Camilia Dornelles De Mattos

Graduate Student Theses, Dissertations, & Professional Papers

Cells are constantly monitoring their extracellular environment for danger signals that warn of imminent threats. When cells are killed by physical or other non-infectious injuries, they release concentrated intracellular molecules into the surrounding area. These danger-associated molecules alert other cells that danger is nearby. When cells are killed by pathogens, they release both damage-associated and pathogen-associated signals. Both eukaryotic and bacterial cells sense these molecules and make threat assessments of cellular injury. Here, I show that lysis of Pseudomonas aeruginosa and other bacterial species releases high concentrations of polyamines that are in turn taken up by surviving cells in a …

Juvenile Temperature Regulation In Apis Mellifera (Honey Bee) And The Impacts Of Brood Temperature Requirements On The Colony, Scott Debnam

Graduate Student Theses, Dissertations, & Professional Papers

Little is known about the energetic costs to insects of raising young. Honey bees collectively raise young, or brood, through a series of complex behaviors that appear to accelerate and synchronize the timing of brood maturation. These include maintaining the brood nest at warmer and consistent temperatures and the exceptional activity of "heater bees." The temperature at which juvenile insects are raised can profoundly affect their development. Apis mellifera (Honey bees) cope with temperature-dependent development via social behavior that maintains the relatively high and constant temperatures within the nest where the brood are raised. Yet juvenile honey bee development is …

The Sticks Of Judah And Joseph: Reflections On Defending The Kingdom, Joseph M. Spencer

Faculty Publications

I wish to pursue two tasks simultaneously in this essay. First, in line with its title, I will address a very old matter of interpretation. I aim to explain as definitively as possible how to make sense of the relationship between Ezekiel 37:15–19, with its talk of the sticks of Judah and Joseph, and the claims of the Restoration, which include somehow connecting the stick of Joseph to the Book of Mormon. Second, in line with the subtitle of this essay, I wish to draw a crucial lesson from the history of how Latter-day Saints have dealt with this issue …

Order Of Operations In Sociophonetic Analysis, Joseph A. Stanley

Faculty Publications

In modern sociophonetic data analysis, a researcher makes numerous decisions when processing their data. Many of the “big” decisions include how data is collected, how audio is transcribed, how these transcriptions are aligned to the audio, and how acoustic measurements are extracted. Once a spreadsheet of numbers has been generated, further decisions must be made regarding normalization, detecting and handling outliers, and excluding tokens irrelevant to the research question. This paper takes a closer look at this second group of decisions—those made after acoustic measurements have been extracted—and shows that the order in which they are applied can have significant …

How Sample Size Impacts Pillai Scores: And What Sociophoneticians Should Do About It, Joseph A. Stanley, Betsy Sneller

Faculty Publications

Pillai scores in Sociolinguistics

• A way to quantify overlap in multiple dimensions (e.g., F1, F2, duration) (Hay et al., 2006; Nycz & Hall-Lew 2013)
• Some concern about unequal vowel categories sizes (Johnson 2015; convo on Twitter June 2, 2021)
• Our solution: a big simulation to show exactly what impact sample size has on Pillai scores

The Simulation

1. Start with a single bivariate normal distribution.

2. Sample two “vowel classes” from this distribution. – Ground Truth is they’re merged.

3. Calculate the Pillai score – Should be close to 0 because they’re merged!

4. Repeat many, many times.

Vowels Can Merge Because Of Changes In Trajectory: Prelaterals In Rural Utah English, Joseph A. Stanley, Lisa Morgan Johnson

Faculty Publications

Overview

• Front vowels: tense-lax pairs getting closer in apparent time.
• Back vowels: three-way convergence of WOLF, JOLT, and MULCH.
• This data suggests a merger by approximation.

Expanding to trajectories gives greater insight into this type of merger.

• Kinda like a zipper.

Greater detail in this merger by approximation.

• The nuclei don’t appear to trigger the shift
• The lateral gradually increases its influence, and the nucleus follows.

Trajectories are potentially important for discovering how vowels shift.

• More recent techniques can allow us to answer these questions.

Mental Illness As A Vulnerability For Sexual Assault: A Retrospective Study Of 7,455 Sexual Assault Forensic Medical Examinations, Leslie Miles, Julie L. Valentine, Linda Mabey, Nancy R. Downing

Faculty Publications

Background: Persons with severe mental illness (MI) are at a high risk of becoming victims of sexual assault (SA). Vulnerability for SA with any type of MI is unknown. This study aimed to identify the prevalence of preexisting MI and other significant factors in patients reporting preexisting MI at the time of their SA medical forensic examinations (SAMFEs).

Method: A retrospective SAMFE chart review of patients ( N = 7,455) from 2010 to 2020 was conducted. Sexual assault nurse examiners completed SAMFEs. Inclusion criteria included (a) aged 14 years and older, (b) completed SAMFE with SA kit evidence collection, and …

Older Adults And Suicide As Examined Through The Lens Of Joiner's Interpersonal Theory Of Suicide, Pamela Holmes

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Older adults face the highest rates of suicide of all age groups. The older adult population is not a homogenous group, and each age range—young old, middle old, and oldest old—has specific risk factors. Although Joiner’s interpersonal theory of suicide (IPTS) has been deemed valid among these age groups, it has not been specifically researched in older adults in each older age range. Due to lack of research and low reporting rates, not enough is known to develop specific detection and prevention measures targeting this population. This paper addresses the application of Joiner’s IPTS to both genders in each of …

"The Working World Is A Minefield": Counterstories Of Job Loss, Rachel Collier Murdock, Matt Baker, Stacy Tye-Williams

Faculty Publications

This study examines narratives told by employees who experienced involuntary job loss. Results expand on previous narrative research investigating the American Dream master narrative and job loss as related to the neoliberal claim that those who work hard will be successful. The study investigated the master narrative’s implications for job loss that if someone loses their job, they must be either flawed or a bad worker. Contributions include a new redeemed-resolved identity construction by individuals who narrated job loss as an opportunity to correct some flaw in either their character or work life and to emerge a better, changed worker. …

A Framework For Phronetic Ldt Theory, Jason K. Mcdonald

Faculty Publications

My purpose in this chapter is to offer a reimagined view of theory in the field of learning design and technology (LDT). Instead of viewing theory as an external storehouse of knowledge, or a rule-like system for professionals to apply, in this framework theory is viewed as an orienting aid that supports practitioners as they refine their personal capacities for perception, discrimination, and judgment. Theory plays this orienting role as it offers insights into LDT-relevant practical knowledge, productive heuristics, points professionals towards opportunities to act, or identifies significant patterns and forms of excellence to which they can pay attention as …

Role Of Morphological Awareness In Language And Literacy In Children With And Without Developmental Language Disorder, Melissa Phelan

Graduate Student Theses, Dissertations, & Professional Papers

Past research has shown phonological awareness is highly correlated with language and literacy success in children with and without Developmental Language Disorder (DLD), but a less examined area of language and literacy is morphological awareness. Delayed morphology in children with DLD has been studied extensively in spoken language, but relatively little in written language in the DLD population. This study explored two research questions: 1) Is morphological awareness related to language and literacy success in children with and without DLD, and 2) Is morphological awareness impaired for those children with DLD and dyslexia similarly to that of phonological awareness. A …

The Influence Of The First-Year Seminar Participation On Student Retention, Sahar Sanavi

Graduate Student Theses, Dissertations, & Professional Papers

College student retention is a complex phenomenon influenced by a myriad of factors and with wide-ranging implications for university function. First-year seminar is one approach to increase first-year student retention through involvement, engagement, and integration. This quantitative study examines the influence of first-year seminar on retention of first-year, full-time, four-year degree-seeking students who matriculated during the fall 2016, 2017, 2018 semester and remained enrolled for fall 2017, 2018, 2019 semester at six institutions in two Northwest states in the United States.

This study utilized an odds ratio to investigate whether first-year seminar participation had a statistically significant influence on the …

Unleaded: Montana’S Silent Epidemic, Erica Zurek

Graduate Student Theses, Dissertations, & Professional Papers

Lead is a cumulative toxin that can affect multiple systems in the human body. Exposure occurs through various sources, such as outdated and deteriorating infrastructure, paint, soil and drinking water. This project, a three-part audio series on lead exposure in Montana highlights various paths of exposure and how young children under age six years of age are particularly vulnerable. Part one is a story about a new state requirement to test all k-12 schools for lead in water fixtures. Part two: A house remodel exposes a family’s children to lead. Getting a diagnosis wasn’t easy. Part three: A look at …

Three New Federal Laws Aid New York’S Compliance With Climate Goals, Michael B. Gerrard, Edward Mctiernan

Faculty Scholarship

The New York Climate Leadership and Community Protection Act of 2019 (CLCPA) requires total statewide greenhouse gas emissions to be reduced 40% from 1990 levels in 2030 and 85% in 2050, with a goal (aided by offsets) of 100% by 2050. It also requires 70% of electricity demand in 2030 to be met by renewables, and 100% from “zero emissions” sources (meaning renewables plus nuclear) in 2040.

Do Privacy Assurances Work? A Study Of Truthfulness In Healthcare History Data Collection, Tamara M. Masters, Mark Keith, Rachel Hess, Jeffrey L. Jenkins

Faculty Publications

Patients often provide untruthful information about their health to avoid embarrassment, evade treatment, or prevent financial loss. Privacy disclosures (e.g. HIPAA) intended to dissuade privacy concerns may actually increase patient lying. We used new mouse trackingbased technology to detect lies through mouse movement (distance and time to response) and patient answer adjustment in an online controlled study of 611 potential patients, randomly assigned to one of six treatments. Treatments differed in the notices patients received before health information was requested, including notices about privacy, benefits of truthful disclosure, and risks of inaccurate disclosure. Increased time or distance of device mouse …

An Attack On Local Authority, Richard Briffault, Kim Haddow

Faculty Scholarship

In the 2021 legislative sessions, Republican state lawmakers introduced a glut of preemption bills aimed at giving states more power over the administration of local government operations, signifying a new, deeper level of state interference into the inner workings of cities and counties. . . . Entering the 2021 legislative sessions, Republican state lawmakers used their power to respond to the events of 2020 – the pandemic, the racial justice movement, the presidential election, and what they perceived to be local government overreach (Brownstein 2021) – by introducing a surge of preemption bills aimed at appropriating the machinery of local …

The Input Fallacy, Talia B. Gillis

Faculty Scholarship

Algorithmic credit pricing threatens to discriminate against protected groups. Traditionally, fair lending law has addressed such threats by scrutinizing inputs. But input scrutiny has become a fallacy in the world of algorithms.

Using a rich dataset of mortgages, I simulate algorithmic credit pricing and demonstrate that input scrutiny fails to address discrimination concerns and threatens to create an algorithmic myth of colorblindness. The ubiquity of correlations in big data combined with the flexibility and complexity of machine learning means that one cannot rule out the consideration of protected characteristics, such as race, even when one formally excludes them. Moreover, using …

Systemic Stewardship, Jeffrey N. Gordon

Faculty Scholarship

This Article frames a normative theory of stewardship engagement by large institutional investors and asset managers that is congruent with their theory of investment management — “Modern Portfolio Theory” — which describes investors as attentive to both systematic risk as well as expected returns. Because investors want to maximize risk-adjusted returns, it will serve their interests for asset managers to support and sometimes advance shareholder initiatives that will reduce systematic risk. “Systematic stewardship” provides an approach to “ESG” matters that serves both investor welfare and social welfare and fits the business model of large, diversified funds, especially index funds. The …

The In Rem/In Personam Distinction And Partitioning For Persistence, Shyamkrishna Balganesh, Leo Katz

Faculty Scholarship

In the second of his two famous articles, Hohfeld seeks to do for the in rem/in personam distinction what he did so persuasively in his first for the terminology of rights, claims, duties, privileges, powers, immunities, and disabilities, which was to identify their essence, and to thereby describe the “natural kind” (in more modern parlance) lurking beneath the thicket of confused juristic rhetoric. The thesis in this second article, however, is a simpler and in some way more beguiling one than in his first. He claims that what the distinction between in rem and in personam jural relations comes down …

Foundations Of Online Learning: Challenges And Opportunities, Christine Greenhow, Charles R. Graham, Matthew J. Koehler

Faculty Publications

Online learning—learning that involves interactions that are mediated through using digital, typically internet-based, technology—is pervasive, multi-faceted, and evolving, creating opportunities and challenges for educational research in the wake of the COVID-19 pandemic. In this special issue, we advance an interdisciplinary agenda for online learning research at the intersection of educational technology, educational psychology, and the learning sciences. In this first article in the issue, we define online learning including its variants, review historical and current contexts, explore its multidimensionality, and assert key issues shaping contemporary online learning. We propose five important lenses: community, engagement, pedagogy, equity, and design-based research, through …

The Innovation And Reporting Consequences Of Financial Regulation For Young Life-Cycle Firms, Abigail Allen, Melissa F. Lewis-Western, Kristen Valentine

Faculty Publications

Firm life-cycle stage reflects a firm’s current strategic direction toward exploration independent of age or size. We provide evidence that young life-cycle firms are particularly vulnerable to negative innovation consequences from financial regulation but do not appear to experience any compensating financial reporting quality (FRQ) benefits. Using a generalized difference-indifferences design around Sarbanes Oxley Act of 2002 (SOX), we document a significant reduction in both research and development (R&D) spending and innovation outputs for young life-cycle stage firms after regulation. Declines in innovation manifest both from the diversion of scarce resources and from the imposition of an organizational culture mismatched …

Preparer Opposition And Strategic Implementation Of Governmental Accounting Standards: Evidence From Public Pension Accounting Reform, Abigail Allen, Reining C. Petacchi

Faculty Publications

Widely acknowledged as one of the most controversial standards in governmental accounting, GASB 67/68 radically altered both the recognition and measurement for defined benefit public pensions. The standards require the recognition of previously only disclosed unfunded pension liabilities and increase the magnitude of reported pension liabilities by requiring the partial incorporation of a market-based discount rate. While the recognition proposal was unaltered from its initial conception to the final standards, the discount rate proposal was significantly attenuated after the initial proposal met with unanimous preparer opposition. Accordingly, we examine what incentives drive preparer lobbying positions, whether such lobbying is aligned …

Do Auditors’ Incentives Affect Materiality Assessments Of Prior-Period Misstatements?*, Brant E. Christensen, Roy Schmardebeck, Timothy Seidel

Faculty Publications

We examine whether auditors' incentives affect materiality assessments of prior-period misstatements. Interviews with global network firm partners reveal consistency across firms in the process used to assess prior-period misstatements and highlight points in the process where judgments are most susceptible to auditors’ conscious or subconscious biases. In related empirical tests, we find that auditors assess misstatements as less material (i.e., misstatements are disclosed less prominently) when auditors face greater engagement risk (comprised of the risk of litigation and reputation loss) or have greater incentives to please important clients. These effects only occur when auditor incentives to avoid further litigation or …

Perceptions Of Robotic Process Automation In Big 4 Public Accounting Firms: Do Firm Leaders And Lower-Level Employees Agree?, Lauren A. Cooper, D. Kip Holderness, Trevor L. Sorensen, David A. Wood

Faculty Publications

The use of Robotic Process Automation (RPA) is a recent innovation in the public accounting industry, and the Big 4 firms are at the forefront of its implementation. This paper examines how the adoption and use of RPA is affecting the perceived work experience of firm leaders and lower-level employees at Big 4 accounting firms. We interview 14 RPA leaders, survey 139 lower-level employees, and compare and contrast their responses. We find that the two groups generally agree that RPA is having a positive influence on the profession. Both groups believe that RPA is positively changing the work employees perform …

The Relevance Of Non-Income Tax Relief*, Michael S. Drake, Ryan V. Hess, Jaron H. Wilde, Braden M. Williams

Faculty Publications

Governments regularly offer non-income tax relief to attract business investment. However, it is unclear whether or how markets impound information about the relief into security prices. We use novel data from retrospective public records to examine the information content of non-income tax relief. We predict and find that the receipt and magnitude of this relief are both strongly associated with recipients’ future accounting performance and future abnormal returns. We further find that abnormal returns associated with the relief cluster around future earnings information events. In combination, this evidence suggests that non-income tax relief is value-relevant but is incorporated into prices …
