Biclustermd: An R Package For Biclustering With Missing Values, John Reisner, Hieu Pham, Sigurdur Olafsson, Stephen Vardeman, Jing Li

The R Journal

Biclustering is a statistical learning technique that attempts to find homogeneous partitions of rows and columns of a data matrix. For example, movie ratings might be biclustered to group both raters and movies. biclust is a current R package allowing users to implement a variety of biclustering algorithms. However, its algorithms do not allow the data matrix to have missing values. We provide a new R package, biclustermd, which allows users to perform biclustering on numeric data even in the presence of missing values.

Modeling Regimes With Extremes: The Bayesdfa Package For Identifying And Forecasting Common Trends And Anomalies In Multivariate Time-Series Data, Eric J. Ward, Sean C. Anderson, Luis A. Damiano, Mary E. Hunsicker, Michael A. Litzow

The R Journal

The bayesdfa package provides a flexible Bayesian modeling framework for applying dynamic factor analysis (DFA) to multivariate time-series data as a dimension reduction tool. The core estimation is done with the Stan probabilistic programming language. In addition to being one of the few Bayesian implementations of DFA, novel features of this model include (1) optionally modeling latent process deviations as drawn from a Student-t distribution to better model extremes, and (2) optionally including autoregressive and moving-average components in the latent trends. Besides estimation, we provide a series of plotting functions to visualize trends, loadings, and model predicted values. A secondary …

Serological Survey And Pathogen Exposure Of Adult Female White-Tailed Deer In The Western Dakotas, Katherine L. Moratz, Bailey S. Gullikson, Eric S. Michel, Daniel M. Grove, Jonathan A. Jenks, William Jensen

The Prairie Naturalist

Establishing baseline values for pathogen exposure and nutritional indices is necessary to monitor population health. However, little is known about white-tailed deer (Odocoileus virginianus) pathogen exposure and nutritional condition in the Northern Great Plains. Our objective was to assess pathogen exposure and establish nutritional indices for female white-tailed deer in Dunn and Grant counties, North Dakota and Perkins County, South Dakota. During 2014, we collected blood serum from 150 adult female white-tailed deer. Pathogens with the highest antibody prevalence included West Nile Virus (WNV; 85%), epizootic hemorrhagic disease (48%), and malignant catarrhal fever (32%). Serum values for creatine …

Bats Of The Loess Hills Ecoregion Of Southeast Nebraska, Virgil Brack Jr, Dale W. Sparks, Darwin C. Brack

The Prairie Naturalist

We surveyed bats at 49 sites in the Loess Hills Ecoregion of southeastern Nebraska, along the western edge of the eastern forest biome in eastern Richardson, Nemaha, and Otoe counties. We completed this study shortly before the northern long-eared bat (Myotis septentrionalis) was listed by the United States Fish and Wildlife Service under the Endangered Species Act. The expectation of listing, along with potential presence of the endangered Indiana bat (Myotis sodalis), motivated the study. We captured 183 bats of five species: eastern red bat (Lasiurus borealis) (n = 103; 56 %), big brown …

Structured Sensemaking Of Videographic Information Within Dataphoric Space, Michael J. Pritchard

Masters Theses & Doctoral Dissertations

Attempts to create a structured sensemaking model have proven difficult. Much of the research today has evolved into a cacophony of conceptual models. Many of these sensemaking models have been proposed but not tested. Using structural equations, a unified model of sensemaking was developed and tested. This structured sensemaking model contains five sensemaking constructs: chaos, anchoring, articulation, retrospection, and identity. This model was tested using data collected from 224 educationally focused YouTube videos. The confirmatory factor model developed for this research has a measured Comparative Fit Index of 0.979, a measured Standardized Root Mean Square Residual of 0.078, and a …

’Let’S Call Ourselves The Super Elite’: Using The Collective Behavior Tradition To Analyze Trump’S America, Todd Nicholas Fuist, Rhys Williams

Sociology: Faculty Publications and Other Works

The mid‐twentieth century “collective behavior” school asserted that (1) collective behavior—the actions of crowds, movements, and other gatherings—had distinct dynamics; (2) such action was often “nonrational,” or not governed by cost‐benefit calculation; and (3) collective behavior could pose a threat to liberal democracy because of these features. While this tradition fell out of scholarly favor, the 2016 election has given us empirical reasons to revisit some elements of collective behavior approaches. We argue for three key orienting concerns, drawn from this tradition, to understand the current political era. First is a focus on authoritarianism and populism, particularly among those who …

Incorporating In-Source Fragments Improves Metabolite Identification Accuracy In Untargeted Lcms And Lcms/Ms Datasets., Brian C Searle, Jacob C Lippincott, Phillip M Seitzer

Articles, Abstracts, and Reports

In untargeted metabolomics experiments library search engines detect metabolites using several features, including precursor mass, isotopic distribution, retention time, and MS2 fragmentation. Matching acquired MS2 to library spectra is vital as numerous compounds share molecular formulas, resulting in identical precursor measurements and similar retention times. However, many metabolomics experiments are still collected using LC-MS only, and even in LC-MS/MS experiments many precursors lack MS2 spectra due to the stochastic nature of data dependent acquisition. We observe that when metabolites ionize they can produce unanticipated MS1 features resulting from neutral losses, in-source fragmentation, multimerization, and adducts. Here we present a new …

I May Be Slightly Broken: Experiences Of Children Of Parents With Personality Disorders, Miriam Tepper

Social Work Theses - Archive

Child abuse is defined as any emotional, psychological or physical abuse or neglect inflicted on a child, that causes distress and impaired functioning for that child. A child’s caregiver was reported to be the main source of child abuse, with increasing chances if the parent struggles with a mental health disorder and or co-morbid substance use disorder or physical issues. The mental health issues that have been noted as a significant source of abuse include a parent who struggles with a personality disorder including borderline personality disorder (BPD) and narcissistic personality disorder (NPD). These personality disorders stem from years of …

I, Gamer: Addressing Toxic Ludology And Narratology In The Gamer Discourse Community Through Reinterpreting Video Games As Hypertexts, Andrew S. Latham

English Dissertations - Archive

My research examines two points crucial to the continuing discipline of video game rhetoric. First, it discusses the formation of toxic ludology and narratology in the gamer discourse community over the course of decades. I begin in the 1980s, showing how privilege in the gamer discourse community sowed toxicity that culminated in Gamergate in the 2010s, an event that is still ongoing and destructive to player discourse. In this half of the dissertation, I explore how uninviting gamers can be to new players and also provide examples where more progressive gamers are showing signs of being more inviting to new …

Ethics In Academic Research And Scholarship: An Elucidation Of The Principles And Applications, Olajide O. Agunloye

Journal of Global Education and Research

Responsible, respectable, and successful engagement in research and scholarship in academia requires adherence to certain basic professional ethical principles to sustain the fidelity of academic work and the integrity of the researcher-scholar. This is more so for works which are intended for dissemination, information, attention, and consumption of audiences beyond the researcher-scholar’s proximal academic habitat. Ethical principles in research and scholarship apply whether the intended work, to be made public, is a conceptual scholarly narrative of ideas and thoughts or a narration of actual scientific-process-based research. This paper explores some of the key ethical principles in research and scholarship, their …

A Governance Perspective For System-Of-Systems, Polinpapilinho F. Katina, Charles B. Keating, James A. Bobo, Tyrone S. Toland

Engineering Management & Systems Engineering Faculty Publications

The operating landscape of 21st century systems is characteristically ambiguous, emergent, and uncertain. These characteristics affect the capacity and performance of engineered systems/enterprises. In response, there are increasing calls for multidisciplinary approaches capable of confronting increasingly ambiguous, emergent, and uncertain systems. System of Systems Engineering (SoSE) is an example of such an approach. A key aspect of SoSE is the coordination and the integration of systems to enable ‘system-of-systems’ capabilities greater than the sum of the capabilities of the constituent systems. However, there is a lack of qualitative studies exploring how coordination and integration are achieved. The objective of this …

Raping Indian Country, Sarah Deer, Elizabeth Kronk Warner

Utah Law Faculty Scholarship

In this article, we have examined the policies of the Trump Administration as they relate to extractive development on and near Indian country, and policies related to the protection of Native people from rape and sexual assault. As demonstrated above, the Administration’s policies are likely to increase both the environmental and physical vulnerabilities of Native people. Native people will not only likely face exasperated physical insecurity, but their environments will likely be increasingly stripped on natural resources. As a result, the raping of Indian county continues. But, this article is not without hope. At least two ways forward, improvements upon …

Japanese Paper And Paper Conservation, Kei Takahashi

Honor’s College Freeman Research Journal

Washi is a Japanese handmade paper which has very long traditions. There are many types of washi in Japan but there are three main types of paper which are the kozo, mitsumata, and gampi paper. Kozo paper is made of mulberry fibers and the most well-known and has the highest production in Japan. Mitsumata and Gampi paper are made of tree of daphne fibers but the process of these two papers are different and Gampi paper is the highest quality of paper compared to the other two types papers. Before washi was created, the handmade paper originally came from …

Small Group Learning Is Associated With Reduced Salivary Cortisol And Testosterone In Undergraduate Students, Kristin Snopkowski, Kathryn Demps, Ross Griffiths, Karen S. Fulk, Scott May, Kimberly Neagle, Kayla Downs, Michaela Eugster, Tessa Amend

Anthropology Faculty Publications and Presentations

Small group learning activities have been shown to improve student academic performance and educational outcomes. Yet, we have an imperfect understanding of the mechanisms by which this occurs. Group learning may mediate student stress by placing learning in a context where students have both social support and greater control over their learning. We hypothesize that one of the methods by which small group activities improve learning is by mitigating student stress. To test this, we collected physiological measures of stress and self-reported perceived stress from 26 students in two undergraduate classes. Salivary cortisol and testosterone were measured within students across …

Feeling It: Toward Style As Culturally Structured Intuition, Keith Rhodes

Department of English: Faculty Publications

I have been moved to write a serious article about teaching style not because I have great and earth-shaking method to impart, but in some sense because I do not, even after years of study—including the small bit of empirical research at the core of this article. Style, as it turns out, remains as difficult, complex, and ultimately intuitive as most of the rest of writing. I hope, ultimately, to encourage writing teachers to focus more attention on style, basing approaches on what we already know rather than waiting and hoping for some flawless system to materialize. Indeed, by the …

Cultural Heritage And Local Ecological Knowledge Under Threat: Two Caribbean Examples From Barbuda And Puerto Rico, Rebecca Boger, Sophia Perdikaris, Isabel Rivero-Collazo

School of Global Integrative Studies: Faculty Publications

While the impacts to the infrastructures in Barbuda and Puerto Rico by Hurricanes Irma and Maria have received attention in the news media, less has been reported about the impacts of these catastrophic events on the tangible and intangible cultural heritage of these Caribbean islands. This report provides an assessment of the impacts on the cultural heritage by these storms; tangible heritage includes historic buildings, museums, monuments, documents and other artifacts and intangible heritage includes traditional artistry, festivities, and more frequent activities such as religious services and laundering. While the physical destruction was massive, the social contexts in which these …

Distinct Aspects Of The Early Environment Contribute To Associative Memory, Cued Attention, And Memory-Guided Attention: Implications For Academic Achievement, Maya L. Rosen, Andrew N. Meltzoff, Margaret A. Sheridan, Katie A. Mclaughlin

Neuroscience: Faculty Publications

Childhood socioeconomic status (SES) is associated with numerous aspects of cognitive development and disparities in academic achievement. The specific environmental factors that contribute to these disparities remain poorly understood. We used observational methods to characterize three aspects of the early environment that may contribute to SES-related differences in cognitive development: violence exposure, cognitive stimulation, and quality of the physical environment. We evaluated the associations of these environmental characteristics with associative memory, cued attention, and memory-guided attention in a sample of 101 children aged 60–75 months. We further investigated whether these specific cognitive abilities mediated the association between SES and academic …

Exculpatory Evidence Pre-Plea Without Extending Brady, Brian Sanders

University of Chicago Law Review

Innocent defendants sometimes plead guilty. This is a problem. Some suggest fixing this problem with a constitutional requirement that prosecutors disclose exculpatory evidence before a defendant pleads guilty. A circuit split has thus developed concerning whether Brady, which requires disclosure of exculpatory evidence, extends to the pre-plea context. The Supreme Court’s jurisprudence, however, likely bars a constitutional requirement for pre-plea disclosure of exculpatory evidence. Faced with this exigency, this Comment argues that contract law should form the legal basis for pre-plea disclosure. Specifically, the contract doctrine of constructive fraud provides a suitable remedy. While big boy clauses, which defeat constructive …

My Palate Hung With Starlight: A Gastrocritical Reading Of Seamus Heaney’S Poetry, Anke Klitzing

Articles

Nobel-prize winning poet Seamus Heaney is celebrated for his rich verses recalling his home in the Northern Irish countryside of County Derry. Yet while the imaginative links to nature in his poetry have already been critically explored, little attention has been paid so far to his rendering of local food and foodways. From ploughing, digging potatoes and butter-churning to picking blackberries, Heaney sketches not only the everyday activities of mid-20th century rural Ireland, but also the social dynamics of community and identity and the socio-cultural symbiosis embedded in those practices. Larger questions of love, life and death also infiltrate the …

Biological Sciences Faculty Publications

Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non-standardized sampling methodology and analyses of notoriously scale-dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation on species’ assemblages, it is necessary to have the underlying data on species abundances and sampling intensity, so that standardization can be achieved. To accomplish …

External Influences And Internal Construction Of Self, Serra Raven Shuford

All Theses

Throughout our lives, a plethora of influences in some way or another, determine who we are by constructing our identities and the perception of who we are. Understanding this is important as we attempt to discover self, amongst our experiences. My work investigates the way that cultural, familial, environmental, social, and other external factors affect the internal construction of self. The accumulation of imposed influences leaves little room for self which calls to question, “who are we if not for our predisposed circumstances?”. Through the collective use of textures, patterns, and colors found in fabric, the sculptures in this work …
