Compmodels: A Suite Of Computer Model Test Functions For Bayesian Optimization, Tony Pourmohamad Dec 2021

Compmodels: A Suite Of Computer Model Test Functions For Bayesian Optimization, Tony Pourmohamad

The R Journal

The CompModels package for R provides a suite of computer model test functions that can be used for computer model prediction/emulation, uncertainty quantification, and calibration. Moreover, the CompModels package is especially well suited for the sequential optimization of computer models. The package is a mix of real-world physics problems, known mathematical functions, and black-box functions that have been converted into computer models with the goal of Bayesian (i.e., sequential) optimization in mind. Likewise, the package contains computer models that represent either the constrained or unconstrained optimization case, each with varying levels of difficulty. In this paper, we illustrate the use …


Generalized Linear Randomized Response Modeling Using Glmmrr, Jean-Paul Fox, Konrad Klotzke, Duco Veen Dec 2021

Generalized Linear Randomized Response Modeling Using Glmmrr, Jean-Paul Fox, Konrad Klotzke, Duco Veen

The R Journal

Randomized response (RR) designs are used to collect response data about sensitive behaviors (e.g., criminal behavior, sexual desires). The modeling of RR data is more complex since it requires a description of the RR process. For the class of generalized linear mixed models (GLMMs), the RR process can be represented by an adjusted link function, which relates the expected RR to the linear predictor for most common RR designs. The package GLMMRR includes modified link functions for four different cumulative distributions (i.e., logistic, cumulative normal, Gumbel, Cauchy) for GLMs and GLMMs, where the package lme4 facilitates ML and REML estimation. …


Passo: An R Package For Assessing Partial Association Between Ordinal Variables, Shaobo Li, Xiaorui Zhu, Yuejie Chen, Dungang Liu Dec 2021

Passo: An R Package For Assessing Partial Association Between Ordinal Variables, Shaobo Li, Xiaorui Zhu, Yuejie Chen, Dungang Liu

The R Journal

Partial association, the dependency between variables after adjusting for a set of covariates, is an important statistical notion for scientific research. However, if the variables of interest are ordered categorical data, the development of statistical methods and software for assessing their partial association is limited. Following the framework established by Liu et al. (2021), we develop an R package PAsso for assessing Partial Associations between ordinal variables. The package provides various functions that allow users to perform a wide spectrum of assessments, including quantification, visualization, and hypothesis testing. In this paper, we discuss the implementation of PAsso in …


An R Package For Non-Normal Multivariate Distributions: Simulation And Probability Calculations From Multivariate Lomax (Pareto Type Ii) And Other Related Distributions, Zhixin Lun, Ravindra Khattree Dec 2021

An R Package For Non-Normal Multivariate Distributions: Simulation And Probability Calculations From Multivariate Lomax (Pareto Type Ii) And Other Related Distributions, Zhixin Lun, Ravindra Khattree

The R Journal

Convenient and easy-to-use programs are readily available in R to simulate data from and probability calculations for several common multivariate distributions such as normal and t. However, functions for doing so from other less common multivariate distributions, especially those which are asymmetric, are not as readily available, either in R or otherwise. We introduce the R package NonNorMvtDist to generate random numbers from multivariate Lomax distribution, which constitutes a very flexible family of skewed multivariate distributions. Further, by applying certain useful properties of multivariate Lomax distribution, multivariate cases of generalized Lomax, Mardia’s Pareto of Type I, Logistic, Burr, Cook-Johnson’s uniform, …

Fall Field Report, August-November 2021, W. Ross Silcock Dec 2021

Fall Field Report, August-November 2021, W. Ross Silcock

Nebraska Bird Review

INTRODUCTION Recent years have seen increasing reports of birds lingering quite late, and this fall was no exception. Notable groups exhibiting tardy departures were shorebirds and vireos. Tardy shorebirds were record late Solitary Sandpipers, near-record late Dunlin, and late Long-billed Curlew, Ruddy Turnstone, Least and Semipalmated Sandpipers, Long-billed Dowitcher, and Wilson’s Phalarope. Among the vireos, all regular species were at least tardy; record late was a Red-eyed Vireo, a Warbling Vireo was record late for the Panhandle, and a Blue-headed Vireo was second latest on record. Record late was a Barn Swallow, and a Mountain Bluebird was record late in …


Winter Seal-Based Observations Reveal Glacial Meltwater Surfacing In The Southeastern Amundsen Sea, Yixi Zheng, Karen J. Heywood, Benjamin G.M. Webber, David P. Stevens, Louise C. Biddle, Lars Boehme, Brice Loose Dec 2021

Winter Seal-Based Observations Reveal Glacial Meltwater Surfacing In The Southeastern Amundsen Sea, Yixi Zheng, Karen J. Heywood, Benjamin G.M. Webber, David P. Stevens, Louise C. Biddle, Lars Boehme, Brice Loose

Graduate School of Oceanography Faculty Publications

Determining the injection of glacial meltwater into polar oceans is crucial for quantifying the climate system response to ice sheet mass loss. However, meltwater is poorly observed and its pathways poorly known, especially in winter. Here we present winter meltwater distribution near Pine Island Glacier using data collected by tagged seals, revealing a highly variable meltwater distribution with two meltwater-rich layers in the upper 250 m and at around 450 m, connected by scattered meltwater-rich columns. We show that the hydrographic signature of meltwater is clearest in winter, when its presence can be unambiguously mapped. We argue that the buoyant …


Exploring High-Power Distance Among Other Variables In Information Security Policy Compliance, Erasmus Ekpo Etim Dec 2021

Exploring High-Power Distance Among Other Variables In Information Security Policy Compliance, Erasmus Ekpo Etim

Masters Theses & Doctoral Dissertations

Information security threat is one of the significant challenges organizations must deal with, and one component of that challenge is information security policy compliance. Data breaches sometimes happen because employees do not adhere to information security policies. The purpose of the exploratory study was to determine if power distance had a role in information security policy compliance; power distance is the understanding that power distribution is unequal. The research required survey data collected from a high-power distance index country, Nigeria. The Nigerian working class was the population sample; a model was developed based on compliance, descriptive norms, moral beliefs, normative …

Hurricanes And Housing: Highlighting The Ongoing Impact Of Hurricane Michael And The Post-Disaster Housing Problem, Mary Beth Barr Dec 2021

Hurricanes And Housing: Highlighting The Ongoing Impact Of Hurricane Michael And The Post-Disaster Housing Problem, Mary Beth Barr

Architecture Undergraduate Honors Theses

Hurricanes impact individuals and communities on many levels - emotional, physical, mental, financial - to name a few. Every time a hurricane occurs, lives are drastically altered forever. One of the ways that hurricanes impact individuals and communities most powerfully is through the effect that they have on housing. Unleashing uncontrollable damage to infrastructure and the built environment, hurricanes exacerbate housing problems that exist and create new ones where they did not exist before. Hurricane Michael, which catastrophically impacted the Florida Panhandle in 2018, is a case study in which the impact that hurricanes have on housing is prevalent.

(R)-2,5-Dimethoxy-4-Iodoamphetamine [(R)-Doi] Influences Coping Strategies To An Escapable Social Stress, Kevin Thomas Krupp

Dissertations and Theses

Depressive mood disorders are a leading cause of disability worldwide and pharmacological treatments for these disorders are inadequate, requiring new compounds with greater efficacy be investigated. The etiology of depression is heterogeneous; however, it is well established that stress exposure, and the proinflammatory effects of stress have a major role. Psychedelic compounds have rapid and long-lasting anxiolytic and antidepressive effects in humans and animal models of stress induced affective behavior. However, it is not completely understood how these compounds produce such rapid effects. We investigated whether the psychedelic compound (R)-2,5-dimethoxy-4-iodoamphetamine [(R)-DOI], a selective 5-HT2A partial agonist with potent anti-inflammatory properties, …

Seeing Red: Visuality, Violence, And The Making Of Textiles In Early Medieval Enigmatic Poetry, Megan Cavell Dec 2021

Seeing Red: Visuality, Violence, And The Making Of Textiles In Early Medieval Enigmatic Poetry, Megan Cavell

Medieval Feminist Forum: A Journal of Gender and Sexuality

This essay explores a group of thematically related, enigmatic poems in Old English, Anglo-Latin and Old Norse that play with gender through their representations of violent textile production. The tenth-century Exeter Book’s Riddle 56, eighth-century archbishop Tatwine’s Enigmata 11 and 13, and the traditional eddic-style poem Darraðarljóð merge the highly gendered activities of textile production and warfare, questioning binaries and naturalized categories in the process. This process ends with the containment of gender play during the act of solving and interpreting the enigmatic, which restores the status quo. In analysing the space that enigmatic poetry provides for subversive …


Performing Female Sanctity—And Reading It: The Visitatio Sepulchri Of Wilton And Barking Abbey, Sarah Brazil Dec 2021

Performing Female Sanctity—And Reading It: The Visitatio Sepulchri Of Wilton And Barking Abbey, Sarah Brazil

Medieval Feminist Forum: A Journal of Gender and Sexuality

This article discusses two traditions of the Visitatio Sepulcri enacted by women religious in late medieval England, based on the exceptional surviving documentation of liturgical performances from the abbeys of Barking and Wilton. Although these documents do not give access to what happened in these Easter morning performances, they do provide evidence for how the agency of the nuns was encoded into every aspect of their respective liturgical tradition. One of the most striking dimensions of this agency is that the abbesses and nuns shaped performance practices to conceptions of their embodiment. I explore how each abbey grounded authority within …


Transforming Community: Women’S Rape Narratives And Gower’S Confessio Amantis, Jennifer Garrison Dec 2021

Transforming Community: Women’S Rape Narratives And Gower’S Confessio Amantis, Jennifer Garrison

Medieval Feminist Forum: A Journal of Gender and Sexuality

Despite its reputation as socially and politically conservative, John Gower’s fourteenth-century Confessio Amantis highlights sexual violence against women as a central cultural injustice and presents women’s rape narratives as a potentially powerful force for social and political change. This essay focuses on three of Gower’s tales in which women tell their own rape narratives with dramatic and lasting consequences: Mundus and Paulina, Tarquin and Lucrece, and Tereus and Philomena. In all three instances, these women’s narratives of suffering are socially transformative precisely because they threaten the masculine chivalric ideal. For Gower, rape is a direct result of the cultural belief …

Khruangbin On Tour, Meghan Eileen Connolly

Graphic Communication

My senior project, Khruangbin On Tour, creates the opportunity to ideate and promote Khruangbin’s, a three-person band, tour through branding and merchandise. The goal is to create visuals, such as a poster or t-shirt design, to complement their songs and the band as a whole through the use of color palettes, typography, objects and illustrations. The music’s feeling and aesthetic should be reflected in the visual aspects as it represents the artist overall and speaks to the audience.

Predicting Death From Covid-19 Using Pre-Existing Conditions: Implications For Vaccination Triage, Shujie Xiao, Neha Sahasrabudhe, Samantha Hochstadt, Whitney Cabral, Samantha Simons, Mao Yang, David E. Lanfear, Keoki L. Williams

Center for Individualized and Genomic Medicine Research Articles

INTRODUCTION: Global shortages in the supply of SARS-CoV-2 vaccines have resulted in campaigns to first inoculate individuals at highest risk for death from COVID-19. Here, we develop a predictive model of COVID-19-related death using longitudinal clinical data from patients in metropolitan Detroit.

METHODS: All individuals included in the analysis had a laboratory-confirmed SARS-CoV-2 infection. Thirty-six pre-existing conditions with a false discovery rate p<0.05 were combined with other demographic variables to develop a parsimonious prediction model using least absolute shrinkage and selection operator regression. The model was then prospectively validated in a separate set of individuals with confirmed COVID-19.

RESULTS: The study population consisted of 15 502 individuals with laboratory-confirmed SARS-CoV-2. The main prediction model was developed using data from 11 635 individuals with 709 reported deaths (case fatality ratio 6.1%). The final prediction model consisted …


Enhancement Of The Command-Line Environment For Use In The Introductory Statistics Course And Beyond, David W. Gerbing Dec 2021

Enhancement Of The Command-Line Environment For Use In The Introductory Statistics Course And Beyond, David W. Gerbing

Business Faculty Publications and Presentations

R and Python are commonly used software languages for data analytics. Using these languages as the course software for the introductory course gives students practical skills for applying statistical concepts to data analysis. However, the reliance upon the command line is perceived by the typical nontechnical introductory student as sufficiently esoteric that its use detracts from the teaching of statistical concepts and data analysis. An R package was developed based on the successive feedback of hundreds of introductory statistics students over multiple years to provide a set of functions that apply basic statistical principles with command-line R. The package offers …


When A Ban Is Not A Ban: Institutional Work And The Russian Doping Scandal, Mathew Dowling, Spencer Harris, Marvin Washington Dec 2021

When A Ban Is Not A Ban: Institutional Work And The Russian Doping Scandal, Mathew Dowling, Spencer Harris, Marvin Washington

Business Faculty Publications and Presentations

There are fewer cases of such blatant acts to defy and subsequent heroic efforts to rearrange institutional norms than the Russian doping scandal. In adopting a neo-institutional perspective, the authors theorize the scandal as a case of attempted but failed institutional disruption. More specifically, the authors draw upon the institutional change literature and the institutional work perspective to explain the key events surrounding actors’ response to the scandal. The analysis utilized Gioia’s methodological approach to examine secondary empirical data. Findings reveal how stakeholders circumvented traditional governance structures in an attempt to disrupt institutional arrangements, but despite this, much of the …

Going Beyond The Data: Using Testimonies To Humanize Pedagogy On Black Health, Keisha S Ray Dec 2021

Going Beyond The Data: Using Testimonies To Humanize Pedagogy On Black Health, Keisha S Ray

Faculty and Staff Publications

When health professions learners' primary pedagogical experience of Black people and how they become patients is through statistics, it becomes very easy for learners to think of Black people as data points rather than as individuals whose health is often at the mercy of racist institutions. When the human dimension of Black people's health is ignored, specifically the ways that poor health affects individual wellbeing, one of the barriers to proper health for Black patients is how to be seen and considered as a part of a larger problem of systemic racism and institutional injustices as well as individuals whose …
