Human–Environment Interactions At Ta’Ab Nuk Na, A Submerged Maya Salt Works Site In Belize, Cheryl M. Foster, Heather Mckillop, Cory Sills

Geography Faculty Publications and Presentations

Sea-level rise and settlement are investigated at Ta’ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves …

Can Fiction Lead To Prosocial Behaviour? Exclusion, Violence, Empathy, And Literature In Early Modernity, Isabel Jaén-Portillo

World Languages and Literatures Faculty Publications and Presentations

In this short essay, I want to address the relationship between positivity and negativity in affect theories and literary analysis by focusing on the connection between empathy and literature in early modernity, a period when affect theories emerge robustly and are articulated in treatises such as De anima et vita (1538) by Juan Luis Vives (1492–1590) or Nueva Filosofía (1587) by Oliva de Sabuco (1562–1626?).1 We begin with the proposition that fictional narratives may move us to care for others and help them. Indeed, the idea that fiction can make us more empathetic and, thus, turn us into better human …

The Incidence And Modifiable Risk Factors For Necrotizing Enterocolitis Inpreterm Infants A Retrospective Cohort Study, Kelvin Gitau, Roseline Ochieng, Mary Limbe, Caroline Kathomi, James Orwa

Paediatrics and Child Health, East Africa

Objectives: To evaluate the incidence and modifiable risk factors for Necrotizing enterocolitis (NEC) in preterm infants born at ≤32 weeks of gestation weighing <1500 grams, at a private tertiary care hospital in Kenya.

Materials and methods: This retrospective cohort study was conducted at the Aga Khan University Hospital Neonatal Intensive Care Unit (NICU). Preterm infants born at ≤ 32 weeks’ gestation and weighing <1500 grams admitted to NICU between 2009 and 2019, were recruited into the study. The primary outcome was NEC Bell Stage IIa-IIIb based on Modified Bell’s criteria. Maternal and neonatal characteristics were evaluated. The association between variables of interest and NEC was determined using logistic regression analysis and the incidence of NEC for the study period was calculated.

Results: A total of 261 charts of infants born at ≤ 32 weeks’ gestation, weighing <1500 were reviewed, and 200 charts met the inclusion criteria. Fifteen preterm infants developed the primary outcome of interest: NEC Stage ≥2a within the first 30 days of admission. The overall incidence of NEC for the study period was 7.5%. Three risk factors were identified as significantly associated with NEC on multivariate logistic regression analysis: antenatal exposure to steroids (OR = 0.056 CI = 0.003-0.964 p = 0.047), cumulative duration of exposure to invasive mechanical ventilation (OR = 2.172 CI = 1.242-3.799 p = 0.007) and cumulative duration of exposure to umbilical vein catheter (OR = 1.344 CI = 1.08-1.672 p = 0.008).

Conclusions: The overall incidence for the study period of NEC Stage ≥ II a was 7.5%. Exposure to antenatal steroids, duration of mechanical ventilation, and duration of umbilical vein catheterization were …

Pitfalls In Machine Learning-Based Assessment Of Tumor-Infiltrating Lymphocytes In Breast Cancer: A Report Of The International Immuno-Oncology Biomarker Working Group On Breast Cancer, Jeppe Thagaard, Glenn Broeckx, Chowdhury Arif Jahangir, Sara Verbandt, Rajarsi Gupta, Reena Khiroya, Khalid Abduljabbar, Gabriela Acosta Haab, Balazs Acs, Shahin Sayed

Pathology, East Africa

Abstract: The clinical significance of the tumor-immune interaction in breast cancer is now established, and tumor-infiltrating lymphocytes (TILs) have emerged as predictive and prognostic biomarkers for patients with triple-negative (estrogen receptor, progesterone receptor, and HER2-negative) breast cancer and HER2-positive breast cancer. How computational assessments of TILs might complement manual TIL assessment in trial and daily practices is currently debated. Recent efforts to use machine learning (ML) to automatically evaluate TILs have shown promising results. We review state-of-the-art approaches and identify pitfalls and challenges of automated TIL evaluation by studying the root cause of ML discordances in comparison to manual TIL …

Spatial Analyses Of Immune Cell Infiltration In Cancer: Current Methods And Future Directions: A Report Of The International Immuno-Oncology Biomarker Working Group On Breast Cancer, David Page, Chowdhury Jahangir, Sara Verbandt, Rajarsi Gupta, Jeppe Thagaard, Reena Khiroya, Zuzana Kos, Khalid Abduljabbar, Sunil Badve, Shahin Sayed

Pathology, East Africa

Abstract: Modern histologic imaging platforms coupled with machine learning methods have provided new opportunities to map the spatial distribution of immune cells in the tumor microenvironment. However, there exists no standardized method for describing or analyzing spatial immune cell data, and most reported spatial analyses are rudimentary. In this review, we provide an overview of two approaches for reporting and analyzing spatial data (raster versus vector-based). We then provide a compendium of spatial immune cell metrics that have been reported in the literature, summarizing prognostic associations in the context of a variety of cancers. We conclude by discussing two well-described …

The Mediating Role Of Security Anxiety In Internet Threat Avoidance Behavior, Xuan Wang, Yaojie Li, Hanieh Javadi Khasraghi, Cherie Trumbach

Management and Marketing Faculty Publications

In the prior technology threat avoidance literature, inconsistent results are found in examining the relationships between individuals’ perceived susceptibility, perceived severity, and perceived threat, as well as the intention to avoid security threats. One possible explanation for this paradox is lacking consideration of the role of individuals’ negative emotions while facing threats, which is rarely studied before. Therefore, the current study aims to extend the landscape of technology threat avoidance theory by exploring the role of security anxiety in individuals’ responses to security threats from the Internet. Our results demonstrate that Internet users’ risk aversion is strongly influenced by their …

Functional Nanocomposite Coatings For Use In Food Packaging, Camden N. Webb

Master's Theses

Plastics are a class of materials known for their cost and property advantages, increasing significantly in their usage worldwide. Unfortunately, these benefits come with an increasingly concerning environmental impact. A combination of inadequate disposal options and combinations of materials have led to environmental disasters that will impact generations. One of the worst areas for plastic waste is food packaging. Plastic as a material generally excels at durability and longevity, but as food packaging, it outlives its intended purpose by several orders of magnitude. This leads to plastic food packaging materials sitting in landfill or leading to the environment for hundreds …

The Effect Of Message Framing On Parents Of Youth Athletes Attitudes Toward Messages Promoting Healthy Athletic Training Recommendations, John Capra

Communication (PhD) Dissertations

Each year within the United States 73% of children and adolescents participate in some form of organized sport (Aspen Institute, 2020). This participation results in a high rate of injury necessitating 2.6 million emergency room visits each year (Merkel, 2013). Over half of these injuries incurred in youth sport are deemed overuse injuries (Valovich McLeod et al., 2011), which are a leading cause in the high attrition rate seen in youth athletics today (Persson et al., 2020; Mangan, 2018). In order to decrease the prevalence of these overuse injuries, the proper education of, and adherence to, certain recommended sport behaviors …

Phase Stability Of Lead Phosphate Apatite, Jiahong Shen, Dale Gaines Ii, S. Shahabfar, Zi Li, Dohun Kang, Sean Griesemer, Adolfo Salgado-Casanova, Tzu-Chen Liu, Yi Xia, Multiple Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Recently, Cu-substituted lead apatite LK-₉₉ was reported to have room-temperature ambientpressure superconductivity. Here we utilize density functional theory (DFT) total energy and harmonic phonon calculations to investigate the thermodynamic and dynamic stability of two lead phosphate apatites in their pure and Cu-substituted structures. Though Pb₁₀(PO₄)₆O and Pb₁₀(PO₄)₆(OH)₂ are found to be thermodynamically stable (i.e., on the T=₀K ground state convex hull), their Cu-substituted counterparts are above the convex hull. Harmonic phonon calculations reveal dynamic instabilities in all four of these structures. Oxygen vacancy formation …

Immigrational Trauma: An Assessment Of Dental Phobia And Access To Care In Undocumented Individuals, Nora J. Vences Ortiz

Dental Hygiene ETDs

The purpose of this study is to assess immigrational trauma as it relates to dental phobia in accessing care from undocumented individuals. Immigrating from a country to the United States presents with unique challenges. These challenges include language barriers, traumatic experiences and cultural factors. These individuals also have perceived notions regarding their treatment with a physician or dentist as their immigration status may or may not be revealed during their care. If reported, they face deportation to their country of origin placing them in the danger they originally fled from. Survey data was collected using REDCap and distributed to students …

Disrupting the plaque matrix early could help combat this global disease burden. This study evaluated the effect of IONPs on primary gingival keratinocytes.

Purpose: This study aimed to examine existing research regarding nanoparticles and determine if IONPs affect the PGK cell membranes with preliminary research to find the maximum lysis possible with PGK cells.

Methods: IONP core/shell syntheses were performed. Considering keratinocyte characteristics, examining data …

Equipped For Change: A Grounded Theory Study Of White Antiracist School Leaders’ Attitudes And Perceptions Of Racial Consciousness In Educational Leadership, Thomas Joseph Peterson

Education (PhD) Dissertations

There is substantial evidence that issues of race and racism and are common in U.S. public schools, especially those greatly impacted by poverty and racial segregation. Unfortunately, it is highly likely many of these occurrences either go unrecognized, unacknowledged, or are perpetrated unknowingly by White educators and administrators—many of whom are well-intentioned, but lack the critical lens necessary in challenging and dismantling them. For White people, the enculturating normativity of White racial dominance, maintained by the social conditioning of Whiteness, facilitates an environment of racial ignorance and insignificance, leaving most painfully oblivious to the damaging complexities of racism in contemporary …

Putin's Matryoskha: A War Reparations Facility For Rebuilding Ukraine, Lev E. Breydo

Faculty Publications

This Article addresses a critical, trillion-dollar question: How do we hold Russia accountable for the reconstruction of Ukraine? The nation has been devastated by Russia's brutal war of aggression, with tens of thousands killed, millions displaced and its economy in shambles. The enormity of the problem cannot be overstated.

Existing proposals to support Ukraine, including many from prominent scholars, largely focus on seizing Russian assets, particularly central bank reserves "frozen" by sanctions. Such strategies, however, are legally problematic-- likely well beyond the scope of Presidential authority-- and financially insufficient. Moreover, while prospective new legislation could expand presidential powers, it risks …

Visualizing Transaction-Level Modeling Simulations Of Deep Neural Networks, Nataniel Farzan, Emad Arasteh

Engineering Technical Reports

The growing complexity of data-intensive software demands constant innovation in computer hardware design. Performance is a critical factor in rapidly evolving applications such as artificial intelligence (AI). Transaction-level modeling (TLM) is a valuable technique used to represent hardware and software behavior in a simulated environment. However, extracting actionable insights from TLM simulations is not a trivial task. We present Netmemvisual, an interactive, cross-platform visualization tool for exposing memory bottlenecks in TLM simulations. We demonstrate how Netmemvisual helps system designers rapidly analyze complex TLM simulations to find memory contention. We describe the project’s current features, experimental results with two state-of-the-art deep …

The University Of Montana: A History Through The Lens Of Physical Culture, Pe, Health, Athletics, And Recreation 1897-2019: The Evolution Of A Department, Clarence E. Burns

Clarence E. Burns Manuscript: "The University of Montana: A History Through the Lens of Physical Culture, PE, Health, Athletics, and Recreation 1897-2019"

Dr. Burns’ manuscript chronicles how the University of Montana’s Department of Elocution and Physical Culture (1897), one of the university’s oldest programs, evolved to become the Department of Physical Education and later the Department of Health and Human Performance, a program that initially organized “gymnasium practice” and later trained physical education teachers and coaches. The program eventually became one of the most popular campus venues for candidates interested in pre-medicine, physical therapy, nursing, physician assistant certification, and other post-baccalaureate health-care training programs. The manuscript also covers associated history of the university, including changing administrative styles and philosophies, legislative and public …

Revisiting The Diffuse Layer Polarization Of A Spherical Grain In Electrolytes With Numerical Solutions Of Nernst-Planck-Poisson Equations, Qifei Niu

Geosciences Faculty Publications and Presentations

Induced polarization (IP) has been frequently used in solid earth geophysics, hydrology, and environmental sciences. A mechanistic understanding of the IP responses of geological materials is crucial for correctly interpreting field IP measurements. In this study, the fully-coupled, nonlinear Nernst-Planck-Poisson equations are numerically solved to analyze the electrochemical mechanism of diffuse layer polarization around a spherical grain immersed in electrolytes. The numerical results show diffuse layer polarization is formed by the charge separation between counterions in the diffuse layer and charges on the grain surface. Both tangential and normal movements of counterions in the diffuse layer are involved in the …

Whitewater Sound Dependence On Discharge And Wave Configuration At An Adjustable Wave Feature, Taylor A. Tatum, Jacob F. Anderson, Timothy J. Ronan

Geosciences Faculty Publications and Presentations

Stream acoustics has been proposed as a means of monitoring discharge and wave hazards from outside the stream channel. To better understand the dependence of sound on discharge and wave characteristics, this study analyzes discharge and infrasound data from an artificial wave feature which is adjusted to accommodate daily changes in recreational use and seasonal changes in irrigation demand. Monitorable sound is only observed when discharge exceeds ∼35 m³/s, and even above that threshold the sound-discharge relationship is non-linear and inconsistent. When sound is observed, it shows consistent dependence on wave type within a given year, but the …
