Fantasy is a genre that seldom includes black characters. When black characters are present, they often lack the same narrative significance, reliability and character growth that is given to white characters. This can lead to poorly written black characters that lack purpose or fall victim to stereotypical roles and troupes. Depicting black characters in this way can further isolate readers who wish to read about black characters, that are more than just stereotypes, within the fantasy genre. This thesis will examine the writing techniques of character coding and the subversion of stereotypes and how they present a way for black …

Germanium-Tin On Silicon For Integrated Photonics And Integrated Quantum Materials, Shang Liu

Dartmouth College Ph.D Dissertations

Group IV GeSn alloys are attracting attention due to their compatibility with the complementary metal-oxide-semiconductor (CMOS) process. On one hand, Ge-rich GeSn alloys with a tunable direct bandgap are well-suited to infrared (IR) photonic applications such as image sensors. On the other hand, Sn-rich GeSn alloys in diamond cubic α phase are topological quantum materials (TQM) holding potential for important quantum applications. However, directly growing GeSn on Si remains challenging due to the lattice mismatch. Regular epitaxial GeSn grown on a Ge buffer layer is not applicable to many photonic applications including CMOS image sensors (CIS) because the buffer layer …

3-D Reconstruction For Underwater Robots With A Monocular Camera And Lights, Monika Roznere

Dartmouth College Ph.D Dissertations

Before a robot can act, it must perceive its environment. Though, this is not a simple task when considering the challenges in underwater domains -- poor visibility conditions, limited sensor configurations, and lack of readily accessible localization. Underwater robots have, nevertheless, improved dramatically with more extensive sensor and navigation equipment. Robot and sensor use have enabled us to explore all reaches of our oceans. On the other hand, these same robots are not easily accessible or transferable to many practical tasks, including fishery management, infrastructure maintenance, disaster response, site conservation, and ecological surveys. There is a growing need for robots …

Better The Devil You Know: Improved Forecasts From Imperfect Models, Dong Hwan Oh, Andrew John Patton

Research Collection School Of Economics

Many important economic decisions are based on a parametric forecasting model that is known to be good but imperfect. We propose methods to improve out-of-sample forecasts from a misspecified model by estimating its parameters using a form of local M estimation (thereby nesting local OLS and local MLE), drawing on information from a state variable that is correlated with the misspecification of the model. We theoretically consider the forecast environments in which our approach is likely to offer improvements over standard methods, and we find significant forecast improvements from applying the proposed method across four distinct empirical analyses including volatility …

Dentistry And The Law: Taking Records When Leaving A Practice, Dan Schulte Jd

The Journal of the Michigan Dental Association

MDA Legal Counsel Dan Schulte advises on departing partner issues: without contracts, disputes arise regarding records, patient ownership, and practice buyout. Employment and shareholder agreements ensure orderly transitions and protect practice interests. Patient records legally belong to the practice, and transferring them without consent violates laws. Patients can request records, but fees apply. Schulte stresses the importance of agreements to avoid costly disputes and ensure continuity of care.

Identifying Critical Factors That Impact Learning Analytics Adoption By Higher Education Faculty, Michael Knupp

Masters Theses & Doctoral Dissertations

Higher education institutions (HEI) are beginning to invest heavily in learning analytics as a compliment to their existing suite of technologies used to enhance the pedagogical practices of instructors. However, learning analytics continues to see low adoption and integration by higher education faculty. While a culture of learning analytics within HEI is emerging, there is not consensus on the value and effectiveness of the tools and practices that make up the culture. With promises of reduced student dropout rates, improved student outcomes, better course pedagogy and backed by pressures of assessment and accountability, learning analytics is being trumpeted as the …

Forensic Iconography For Image Forgery Detection, Chad R. Johnson

Masters Theses & Doctoral Dissertations

Traditionally, image forgeries were limited to defraud art collectors and falsify documents. The rise of visual media provided legitimate reasons for artists to forge images in the pursuit of more effective storytelling. In all cases these methods required specialized domain knowledge and highly skilled artists. The rise of computers simplified many of these processes, lowering the bar in time, materials, and skill, and thus giving most users access basic tools for altering images. Today, image alteration tools leverage machine learning and artificial intelligence techniques, and can generate incredibly accurate image forgeries. Effective methods for verifying the authenticity of media data …

Reactive Oxygen Species Production In Head Regeneration Of Planaria From Cadmium Exposure, Natalie Gonzalez

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Exposure to cadmium, a pervasive neurotoxic chemical found in our environment, poses significant health risks, disrupting various physiological systems and fostering carcinogenesis. Commonly found in everyday items like cigarettes, batteries, and plastics, cadmium disrupts the equilibrium between reactive oxygen species (ROS) production and cellular repair mechanisms, culminating in oxidative stress and potential cell damage. In toxicological and pharmaceutical research, planarians offer valuable insight for understanding how exposure to chemicals akin to human scenarios can alter biological systems. This experiment addresses the effect cadmium chloride (CdCl₂) has on planarian regeneration and whether antioxidants can mitigate those adverse outcomes. Our …

Space Transformation For Open Set Recognition, Atefeh Mahdavi

Theses and Dissertations

Open Set Recognition (OSR) is about dealing with unknown situations that were not learned by the models during training. In OSR, only a limited number of known classes are available at the time of training the model and the possibility of unknown classes never seen at training time emerges in the test environment. In such a setting, the unknown classes and their risk should be considered in the algorithm. Such systems require not only to identify and discriminate instances that belong to the source domain (i.e., the seen known classes contained in the training dataset) but also to reject unknown …

Caelus: Cubesat Array For The Exploration Of The Uranus System, Dylan George Heidenrich Barnes

Theses and Dissertations

Following recommendations from the 2023-2032 Planetary Science and Astrobiology Decadal Survey, we propose a novel Pre-Phase A level Uranus exploration mission concept that is centered on using swarms of small spacecraft to observe the Uranus system. This mission could act as a supplement to the Flagship Uranus Orbiter and Probe mission detailed in said Decadal Survey. We propose launching a 4,500 kg spacecraft on an Earth-Jupiter-Uranus gravity assist transfer trajectory with a transfer time of six years, launching in 2033 and arriving at Uranus in 2039. This shorter transfer time and accelerated development timeline would allow for an earlier arrival …

Cross-Framework Validation Of Cnn Architectures: From Pytorch To Onnx, Shreya Nandanwar

From Hr Practices To Hr Performance: A Psychological Ownership Meta-Analysis Across Cultures, Franziska M. Renz

American Business Review

This study utilizes psychological ownership theory as theoretical framework to examine high-performance work practices, and attitudinal and behavioral performance as associations of psychological ownership on the population level. Psychological ownership describes a mindset which allows individuals to experience ownership feelings for a target (e.g., organization) regardless of legal ownership rights. Further, psychological ownership theory is integrated with and extended by contingency theory to analyze the moderation effects of societal culture. These effects have been assumed for over 30 years but hardly backed by empirical evidence from cross-cultural samples. Thus, this study analyzes data from 351,919 individuals who participated in 139 …

A Rational Perspective Of Servant Leadership: Towards A Paradigm Shift In Servant Leader Motivation, Kevin J. Hurt, Ross Nolan

American Business Review

Advocates of servant leadership maintain that altruism is the foundational ethic fueling the success of the servant leader. Thus, the foremost requirement of a servant leader is the possession of a concern for others above and beyond his or herself. Researchers have largely neglected the possibility that servant leaders may be, at least partially, motivated by self-interest. We challenge the current foundational ethic attributed with servant leadership and put forth a new ethical perspective. Reviewing four motivational states, from purely other-centered to purely self-centered, we introduce a conceptual model and argue that the proper ethic to ascribe with servant leadership …

Harnessing Social Media For Climate Action In Developing Countries: A Case Study Of Egypt, Nicolas Hamelin, Passant Halawa

Faculty Journal Articles

Like many developing nations, Egypt is facing a climate crisis due to its agricultural dependence and the Nile Delta’s vulnerability. Despite government plans for sustainable development, recent infrastructure projects have resulted in large-scale green space removal. Effective communication about environmental issues can spark pro-environmental behavior and citizen activism. This study explores social media’s potential to bridge this gap in Egypt. Utilizing Facebook AB testing with a limited budget, we reached a significant 2.3% of Egypt’s online population (nearly 2 million users). This study explored message framing, with findings showing that rational posts resonated best while fear appeals had minimal impact. …

Maximization Of Brackish Water Productivity For The Sustainable Production Of Striped Catfish (Pangasianodon Hypophthalmus) And Grain Sorghum (Sorghum Bicolor (L.) Moench) Cultivated Under An Integrated Aquaculture–Agriculture System, Fahad Kimera, Muziri Mugwanya, Khaled Madkour, Mahmoud A.O. Dawood, Hani Sewilam

Faculty Journal Articles

Freshwater scarcity, salinity, and poor soil fertility are the major challenges affecting both food and feed productions in arid and semi-arid regions of the world. Utilization of brackish water in the production of saline-tolerant fish and valuable field crops under an integrated system is promising in the maximization of yield per crop. The aim of this study, therefore, was to (1) assess the effect of saline aquaculture wastewater on the growth, yield, forage quality, and nutritive composition of sorghum seeds and (2) assess the effect of different water qualities on the survival, growth performance, and health status of Pangasianodon hypophthalmus. …

Regulation Of Piezo Channels By Membrane Lipids, Luis Octavio Romero Garcia

Theses and Dissertations (ETD)

In cellular physiology, the transformation of energy from mechanical cues into electrical and/or chemical signals is called mechanotransduction. This ability to sense and react to external and internal mechanical forces is essential for the survival of single cell to multicellular organisms. As such, it is no surprise that mechanotransduction appeared early in the evolutionary history of life on our planet. At the cellular level, mechanotransduction is mediated by proteins and/or protein complexes that respond to mechanical stimuli in different timescales, including but not limited to changes in membrane electric potential, Ca2+ signaling, and gene expression. Among such protein complexes, mechanosensitive …

Conditional Quantization For Uniform Distributions On Line Segments And Regular Polygons, Tsianna Danielle Dominguez

Theses and Dissertations

Quantization for a Borel probability measure refers to the idea of estimating a given probability by a discrete probability with support containing a finite number of elements. If in the quantization some of the elements in the support are preselected, then the quantization is called a conditional quantization. In this thesis, we have investigated the conditional quantization for the uniform distributions defined on the unit line segments and m-sided regular polygons, where m ≥ 3, inscribed in a unit circle.

Affective Life, Mobility And Unity In U.S.-Mexico Transborder Families, Aaron A. Adame Sosa

Theses and Dissertations

There has been abundant research on transnational families and their lived realities, but most of this research focuses on analyzing family relations across long distances. This thesis examines transnational life at the borderlands and develops new frameworks for understanding family unity and separation. Using concepts from the sociology of emotions, I find that economic and opportunity inequalities structure much of transborder life and that the emotional work different family members do for the sake of their family unity is largely based on mobility privilege and the idea that the U.S. is economically better off, even as the relative poverty between …

American Perspectives On The Legitimacy Of Transgender Identities, Sethe Zachman

Department of Sociology: Dissertations, Theses, and Student Research

This mixed-method project examines how Americans’ and Nebraskans’ perceptions of the validity of transgender identities varies by the demographic characteristics of respondents, and how these perceptions are justified. Two representative surveys are used to examine demographic associations with opinion on the cisgender and transgender binary: the 2023 American Values Atlas (AVA) from the Public Religion Research Institute (N=4,788) and the 2022 Nebraska Annual Social Indicators Survey (NASIS) (N=934) from the Bureau of Sociological Research. A measure from the AVA data examines the degree to which respondents believe there are only two genders versus a range of gender identities. The NASIS …

Examining The Effects Of Food Supply On Eastern Oyster (Crassostrea Virginica) Larval Performance And Settlement Potential In Delaware Bay And Mississippi Sound, James C. Klein

Master's Theses

Oyster population maintenance and growth require sufficient larval stocks capable of timely development, growth, and successful metamorphosis, whereby larval performance and settlement potential determines the capacity for a larval cohort to effectively establish into an existing population. Exogenous factors influencing larval performance include temperature, salinity, and particularly food supply. Regarding food, a sufficiently abundant and nutritionally balanced diet composed of protein, lipids, and carbohydrates is critical for successful metamorphosis. The influence of exogenous factors on Crassostrea virginica settlement potential were examined in Delaware Bay and Mississippi Sound by incorporating in situ environmental conditions and food supply metrics into a well-established …

Utilization Of The NuTrack System To Objectively Evaluate Changes In Active And Passive Behaviors Of Group-Housed Nursery Pigs Exposed To An Endotoxin Challenge, Aaron Holliday

Department of Animal Science: Dissertations, Theses, and Student Research

This study aimed to evaluate the changes in activity of group-housed, newly weaned pigs challenged with lipopolysaccharide (LPS). At weaning, pigs (n = 192, 5.73 ± 1.8 kg) were stratified by sex, litter, and body weight (BW) and randomly assigned to one of three treatments (16 pigs/pen, 4 pens/treatment): 1) Saline-injected (SAL), 2) 50% challenged [50%-LPS) – only half of the pigs in a pen (8 pigs) were challenged with LPS and 3) 100% challenged (100%-LPS) – all pigs in a pen were challenged with LPS. Pigs in the SAL and 32 in the 50%-LPS treatment received a 3.0 …

Using Annual Forages To Replace Declining Cool-Season Grass Pasture Availability, Jonathon Matthew Jenkins

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

As land area in grain crop production increases in the US Midwest, perennial pasture availability decreases but the demand increases. Matching the seasonal growth patterns of C₃ and C₄ plant species to grow forages that are complementary allows producers to fill production gaps in otherwise monoculture systems and possibly increase overall productivity. One way to fill the forage production gap of C₃ grass dominated pastures is by producing a warm-season, annual forage in a separate field. However, with continual reductions in land availability, this may not be an option. Using two studies, our objectives were to improve …

Seasonal Comparison Of Air Quality Variables And Evaluation Of Carbon Dioxide And Particulate Measurement Period In Classrooms, Daud Nosham

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Indoor air quality and thermal environmental variables were measured in 55 classrooms in the mid-western United States spanning a full academic year. The studied air quality and environmental factors included carbon dioxide, temperature, relative humidity, particle counts, air velocity, formaldehyde, total volatile organic compounds, carbon monoxide, nitrogen dioxide, and ozone.

Carbon dioxide and Particulate matter concentrations were measured for a four-day measurement period. Then one-day, two-day, and four-day occupied time average concentrations were calculated which were then compared statistically to figure out an appropriate measurement period for these air quality variables. Kruskal Wallis test and Wilcoxon test were used to …

Strong First Order Electroweak Phase Transitions In The Standard Model With A Real Scalar Singlet Extension, Anthony James Hooper

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The large matter-antimatter asymmetry of the universe and whether the electroweak sector has always been broken are currently unanswered by the standard model (SM). One solution that addresses both these concerns is to impose a strong first order electroweak phase transition (SFOEWPT) and ensure electroweak baryogenesis occurs. Models that undergo a SFOEWPT in the early universe create bubbles of the true vacuum that expand until the universe reaches the vacuum expectation value measured today. If the phase transition is strong enough, then these bubbles may generate a detectable stochastic gravitational wave (GW).

However, the SM by itself can only perform …
