Alfred Russel Wallace Notes 22: Stumbling Blocks To An Understanding Of Wallace's Worldview, Charles H. Smith

Faculty/Staff Personal Papers

The writings of Alfred Russel Wallace (1823−1913) present a challenge to modern readers, both for the large range of subjects he entertained, and his unique point of view. In this short treatment, ten ‘stumbling blocks’ to an appreciation of Wallace’s thought are outlined which, it is suggested, have caused problems of interpretation in the past.

Adventurers And Autocrats: The Role Of Authority In The Making Of The English West Indies, 1595-1655, John Clinton Harris

History Dissertations - Archive

After Walter Ralegh made his famous journey to the Orinoco in 1595, English adventurers began the haphazard process of colonizing the West Indies. Initially they tried to follow Ralegh’s efforts in Guiana, but their every effort failed because they lacked access to significant investment capital and did not enjoy the full backing of the crown. After several calamities, Englishmen interested in American colonization turned their efforts towards the Caribbean in 1623. Under the rule of Lord Proprietor James Hay, Earl of Carlisle, and his brutal governors English adventurers enjoyed more success. The key difference in Carlisle’s Caribbean and Ralegh’s Guiana …

Interpreting Sentinel-1 Sar Backscatter Signals Of Snowpack Surface Melt/Freeze, Warming, And Ripening, Through Field Measurements And Physically-Based Snowmodel, Jewell Lund, Richard R. Forster, Elias J. Deeb, Glen E. Liston, S. Mckenzie Skiles, Hans-Peter Marshall

Geosciences Faculty Publications and Presentations

The transition of a cold winter snowpack to one that is ripe and contributing to runoff is crucial to gauge for water resource management, but is highly variable in space and time. Snow surface melt/freeze cycles, associated with diurnal fluctuations in radiative inputs, are hallmarks of this transition. C-band synthetic aperture radar (SAR) reliably detects meltwater in the snowpack. Sentinel-1 (S1) C-band SAR offers consistent acquisition patterns that allow for diurnal investigations of melting snow. We used over 50 snow pit observations from 2020 in Grand Mesa, Colorado, USA, to track temperature and wetness in the snowpack as a function …

Modern Pyromes: Biogeographical Patterns Of Fire Characteristics Across The Contiguous United States, Megan E. Cattau, Adam Mahood, Jennifer K. Balch, Carol Wessman

Human-Environment Systems Research Center Faculty Publications and Presentations

In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to characterize the spatiotemporal patterns of contemporary fire characteristics across the contiguous United States (CONUS). We derived fire variables based on frequency, fire radiative power (FRP), event size, burned area, and season length from satellite-derived fire products and a government records database on a 50 km grid (1984–2020). We used k-means clustering to create a hierarchical classification scheme of areas with relatively homogeneous fire characteristics, or modern …

Data Fusion For Non-Motorized Volume Estimation: A Machine Learning Approach, Md. Mintu Miah

Civil Engineering Dissertations - Archive

ABSTRACT: Despite increased awareness at the state and federal levels of the design and policy concerns associated with nonmotorized infrastructure, communities typically develop strategies to estimate network-wide nonmotorized traffic. However, past research fails to provide the same level of estimation sophistication as motor vehicles due to a lack of investment, which limits increased understanding and capability among communities in network-wide nonmotorized traffic volume estimation. Although previous studies introduce machine learning, Neural Networks, and feature engineering to motorized traffic volume estimation, nonmotorized traffic estimation experiences limited attempts to use these advanced techniques. This dissertation addresses this deficiency in bicycle volume estimation …

Treating Active-Duty Military Members: Best Practices For Common Mental Health Diagnoses Across The Dod, Leah Lawson

Electronic Theses and Dissertations

Due to varying service experiences, active-duty service members endure military related stressors in addition to everyday life stressors. As a result, their risk of mental illness onset increases. Considering that many of the stressors and events are unique to military personnel, it is important to identify best-practice interventions for working with this population opposed to employing civilian best practices. The purpose of this study was to determine what treatment interventions are best-practice when working with active-duty military members diagnosed with the three most common mental disorders (e.g., adjustment disorder, depressive disorders, anxiety disorders) across the Department of Defense (DoD). This …

Covid-19 And Traffic Safety: Exploring Exposure, Crash Frequency And Severity, And Roadway And Network Design, Nicholas N. Ferenchak Ph.D

Publications

Early COVID-19 lockdowns in the first half of 2020 largely kept people at home, thereby reducing motor vehicle traffic levels. Theoretically, reduced traffic exposure should have resulted in reduced motor vehicle crashes. However, a variety of factors may have complicated this relationship. In order to better understand the impact of COVID-19 lockdowns on traffic safety outcomes, we explore fatalities, injuries, and total crashes before and during the lockdowns on both the national and state levels. We provide descriptive statistics and create negative binomial regressions exploring the role of vehicle, user, and built environment factors on traffic safety outcomes. Findings suggest …

Architecture And Agency For Equity In Areas Beyond National Jurisdiction, Lisa M. Campbell, Robin Fail, Rebecca Horan, Leslie Acton, Jeffrey E. Blackwatters

Faculty Publications

The United Nations (UN) Sustainable Development Goals (SDGs) and the UN Decade of Ocean Science for Sustainable Development (Ocean Decade) bring increased attention to various aspects of ocean governance, including equity. One of the Ocean Decade's identified challenges is to develop a sustainable and equitable ocean economy, but questions arise about how to conceptualize the multiple dimensions of equity in an ocean context. These questions become more complex as activities move away from coastal ecosystems and communities into off-shore Areas Beyond National Jurisdiction (ABNJ), where ocean resources are recognized simultaneously as unowned/open access and as common heritage. In this paper, …

Valley-Floor Snowfall In Taylor Valley, Antarctica, From 1995 To 2017: Spring, Summer And Autumn, Madeline E. Myers, Peter T. Doran, Krista F. Myers

Faculty Publications

We present an analysis of the 20 year snowfall dataset in Taylor Valley and the results of a new snow cover monitoring study. Snowfall has been measured at four sites in Taylor Valley from 1995 to 2017. We focus on valley-floor snowfall when wind does not exceed 5 m s-1, and we exclude winter from our analysis due to poor data quality. Snowfall averaged 11 mm water equivalent (w.e.) from 1995 to 2017 across all stations and ranged from 1 to 58 mm w.e. Standard deviations ranged from 3 to 17 mm w.e., highlighting the strong interannual variability of snowfall …

Glaciernet2: A Hybrid Multi-Model Learning Architecture For Alpine Glacier Mapping, Zhiyuan Xie, Umesh K. Haritashya, Vijayan K. Asari, Michael P. Bishop, Jeffrey S. Kargel, Theus Aspiras

Electrical and Computer Engineering Faculty Publications

In recent decades, climate change has significantly affected glacier dynamics, resulting in mass loss and an increased risk of glacier-related hazards including supraglacial and proglacial lake development, as well as catastrophic outburst flooding. Rapidly changing conditions dictate the need for continuous and detailed ob-servations and analysis of climate-glacier dynamics. Thematic and quantitative information regarding glacier geometry is fundamental for understanding climate forcing and the sensitivity of glaciers to climate change, however, accurately mapping debris-cover glaciers (DCGs) is notoriously difficult based upon the use of spectral information and conventional machine-learning techniques. The objective of this research is to improve upon an …

"Just Ice" For Bourbon: The Need For Gis In International Protection Of America's Beloved Spirit, Haley Scott

Indiana Journal of Global Legal Studies

The term "bourbon" has become increasingly popular in markets all over the globe. The popularity of the bourbon trend has been exploited for both labelling liquors and describing nonalcoholic products. Bourbon has several separate definitions, usually differing on the issue of the geographical scope of the spirit's production. The bourbon liquor industry has experienced periods of significant downturn followed by periods of explosive revival, motivated mainly by foreign interest, from countries such as Japan, in the product In the 1970s, Japanese interest in whisky and US bourbon facilitated a resurgence of the then-struggling US bourbon industry. In 2018, production of …

Three Essays In Health Economics, Mir Nahid Mahmud

Legacy Theses & Dissertations (2009 - 2024)

This dissertation comprises three empirical essays. The first essay estimates the long-term health and socioeconomic impact of early life nutritional deficit using the Bangladesh Famine from 1974-1975 as a natural experiment. The second essay investigates if pubic health insurance coverage of “ immigrant children¬” changed as a result of the lift of the “five-year-ban” in the Children Health Insurance Reauthorization Act-2009. The final chapter estimates the relationship between child health conditions and maternal employment using conventional econometric models. To expand the analysis and contribute to the literature, I estimate the relationship by implementing a Multiple Indicator Multiple Causes Model (MIMIC).

Presto : Fast And Effective Group Closeness Maximization, Baibhav L. Rajbhandari

Legacy Theses & Dissertations (2009 - 2024)

Given a graph and an integer k, the goal of group closeness maximization is to find, among all possible sets of k vertices (called seed sets), a set that has the highest group closeness centrality. Existing techniques for this NP-hard problem strive to quickly find a seed set with a high, but not necessarily the highest centrality.

Results show that …

Human-Wildlife Coexistence With Coyotes In Los Angeles County, Ca And Cook County, Il, Alan Eapen

Legacy Theses & Dissertations (2009 - 2024)

The expansion of coyotes (Canis latrans) into urban and suburban areas where human concentration is high has led to human-coyote conflicts often leading to increased management actions against coyotes. Recently in Los Angeles and Cook Counties, municipalities have developed coyote management plans to foster human-wildlife coexistence in an effort to reduce conflict, an emerging concept that promotes the cohabitation of humans and animals in shared landscapes. The thesis investigates coyote management plans and policies concerning human-coyote interactions in Los Angeles and Cook Counties to address human-wildlife. Using a case study analysis of Los Angeles and Cook Counties, this study analyzed …

Relative Effects Of Self-Paced And Machine-Paced Learning Under Computer-Based Training, Eunju Choi

Dissertations

The purpose of this study was to compare the effects of a self-paced instruction versus machine-paced instruction using a computerized format. Instructional applications such as Programmed Instruction and Computer-Based Instruction have long touted the benefits of self-pacing (e.g., teaching machines, Personalized System of Instruction), but direct comparisons of different pacing types are lacking. Some preliminary research suggests that self-pacing may be prone to distraction by competing reinforcers and overall poor self-management of time. As such, it may be possible that machine-paced lessons (based on optimal timings) may foster better learning while retaining other beneficial features of CBI (interactivity, flexibility of …

Competition And Innovation: The Breakup Of Ig Farben, Felix Poege

Faculty Scholarship

The relationship between competition and innovation is difficult to disentangle, as exogenous variation in market structure is rare. The 1952 breakup of Germany’s leading chemical company, IG Farben, represents such a disruption. After the Second World War, the Allies occupying Germany imposed the breakup because of IG Farben’s importance for the German war economy instead of standard antitrust concerns. In technology areas where the breakup reduced concentration, patenting increased strongly, driven by domestic firms unrelated to IG Farben. An analysis of patent texts shows that an increased propensity to patent does not drive the effect. Descriptively, IG Farben’s successors increased …

Analysis of researcher notes, evaluation of textual data produced by interviews, and observations allowed the qualitative investigator to identify emerging themes and …

When The Costs Outweigh The Benefits: Examining Variations In Nulliparous, Term, Singleton, Vertex And Elective Cesarean Delivery Rates Across The United States, 2016-2020, Kathleen Tatro

Electronic Theses and Dissertations

The overutilization of cesarean deliveries is a major public health issue in the United States (U.S.). The rates of cesarean deliveries have increased substantially from the mid 1990s. Low-risk, defined as nulliparous, term, singleton, vertex (NTSV) pregnancies with no medical indication of need, and elective cesarean deliveries have been implicated as drivers of these increases. Elective cesarean deliveries are NTSV cesarean deliveries in which no trial of labor was attempted. There is a lack of clear rationale as to the noted increases in cesarean delivery rates as the evidence shows that these procedures provide no additional health benefits to mothers …

Flora Of Doe Mountain Recreation Area, Johnson County, Tennessee, Benjamin Mccullough

Electronic Theses and Dissertations

A botanical inventory of Doe Mountain Recreation Area (DMRA) in northeastern Tennessee was conducted to help guide conservation-based management. A total of 484 species were found in DMRA, comprising 94 families, and 285 genera, 10 species listed in the state rare plant list, and 76 exotic species. Two species, Liatris virgata and Lycopodiella inundata, were new state records. Water in the Lycopodiella seep was an order of magnitude more acid than at other sites. An analysis of the wildland-urban interface showed that only 13% of the area was classified as uninhabited. The inventory-invasion index, introduced to quantify the relative …

Mississippi Modernism: The River Valley And Race In American Culture, 1892-1945, William C. Palmer

Electronic Theses and Dissertations

Mississippi Modernism looks to the Mississippi River Valley of the last decade of the nineteenth century and the first few decades of the twentieth century to analyze the ways individuals expressed and determined their experience in the changing world. By engaging with theories of modernity from Marshall Berman and the Black modernism of Houston A. Baker, Jr. this work proposes the Mississippi watershed as a region where individuals indulge in the processes of modernism remaking the environments, both urban and rural, surrounding them. By thinking about the “dry” and “wet” valleys envisioned by European settlers as Christopher Morris terms it, …

Long-term flood risk adaptation and decision making are complex because the future is full of deep uncertainties. Flexibility and robustness can be used to deal with future uncertainty. This study developed an integrated modeling framework that extends previous studies to the spatial domain to assess the future flood risks and the cost and benefit of three adaptation measures for four types of buildings in Shanghai. Real options analysis (ROA) and dynamic adaptive policy pathways (DAPP) were integrated to develop a dynamic adaptation pathway and identify robust adaptation options. The results show that: (1) Sea level rise and land subsidence will …

Digital Archival Literacy In The Classroom, Rebecca Fitzsimmons, Elliott Kuecker

Faculty and Staff Publications – Milner Library

Archival literacy has become a popular mode of literacy in the last ten years, given that archival research is not the exclusive purview of historians. Given the amount of open collections and exhibits, the possibility of teaching archival literacy skills is more accessible than ever. Importantly, archival literacy asks us to critically read against the common narrative that archival objects are pure evidence and archivists are neutral agents. Our presentation describes the importance of digital archival literacy and provides examples of implementation in classes, ad hoc workshops, and community engagement. We emphasize that all knowledge is a synthesis of various …
