Novel Hedonic Games And Stability Notions, Jacob Schlueter

Theses and Dissertations--Computer Science

We present here work on matching problems, namely hedonic games, also known as coalition formation games. We introduce two classes of hedonic games, Super Altruistic Hedonic Games (SAHGs) and Anchored Team Formation Games (ATFGs), and investigate the computational complexity of finding optimal partitions of agents into coalitions, or finding - or determining the existence of - stable coalition structures. We introduce a new stability notion for hedonic games and examine its relation to core and Nash stability for several classes of hedonic games.

Representing And Learning Preferences Over Combinatorial Domains, Michael Huelsman

Theses and Dissertations--Computer Science

Agents make decisions based on their preferences. Thus, to predict their decisions one has to learn the agent's preferences. A key step in the learning process is selecting a model to represent those preferences. We studied this problem by borrowing techniques from the algorithm selection problem to analyze preference example sets and select the most appropriate preference representation for learning. We approached this problem in multiple steps.

First, we determined which representations to consider. For this problem we developed the notion of preference representation language subsumption, which compares representations based on their expressive power. Subsumption creates a hierarchy of preference …

Routing And Applications Of Vehicular Named Data Networking, Bassma G. Aldahlan

Theses and Dissertations--Computer Science

Vehicular Ad hoc NETwork (VANET) allows vehicles to exchange important informationamong themselves and has become a critical component for enabling smart transportation.In VANET, vehicles are more interested in content itself than from which vehicle the contentis originated. Named Data Networking (NDN) is an Internet architecture that concentrateson what the content is rather than where the content is located. We adopt NDN as theunderlying communication paradigm for VANET because it can better address a plethora ofproblems in VANET, such as frequent disconnections and fast mobility of vehicles. However,vehicular named data networking faces the problem of how to efficiently route interestpackets and …

Revisiting Absolute Pose Regression, Hunter Blanton

Theses and Dissertations--Computer Science

Images provide direct evidence for the position and orientation of the camera in space, known as camera pose. Traditionally, the problem of estimating the camera pose requires reference data for determining image correspondence and leveraging geometric relationships between features in the image. Recent advances in deep learning have led to a new class of methods that regress the pose directly from a single image.

This thesis proposes methods for absolute camera pose regression. Absolute pose regression estimates the pose of a camera from a single image as the output of a fixed computation pipeline. These methods have many practical benefits …

Research on intensive agricultural features contributes to the social relations of farming, including the means by which farmers mobilize labor and the possible destination of surplus. Lidar provides high-resolution data on ancient houses and agricultural features at a regional scale. This paper uses lidar data from NASA’s G-LiHT airborne imager to derive insights about rural demography, interhousehold cooperation, and subsistence interdependency among the ancient Maya. We assess the differences in intensity of agricultural investment in rural and urban areas of the Río Bec region of southern Campeche and Quintana Roo, Mexico, leading to inferences about regional food exchange and complex …

Examining The Impact Of Performance-Based Funding Equity Premiums On Public Historically Black Colleges And Universities, Adam Blevins

MPA/MPP/MPFM Capstone Projects

Performance-based funding (PBF) policies in the United States have grown both in complexity and popularity over the last two decades. While states seek to utilize these models to enforce accountability at institutions of postsecondary education, the rise of such funding policies has not come without scrutiny. Researchers have found evidence of adverse consequences resulting from these policies, many of which disproportionately impact underrepresented groups of students, smaller schools, and minority-serving institutions (MSIs) such as Historically Black Colleges and Universities (HBCUs). While opponents of the policies have, in some cases, called for the abandonment of PBF models altogether, proponents have sought …

Developing Best Practices For Successful Public-Private Partnerships, Farishta Mccourt

MPA/MPP/MPFM Capstone Projects

Many states and cities find themselves facing several serious long‐term public infrastructure challenges due to rising maintenance costs. Infrastructure funding gaps arose from an inefficient approach to public infrastructure development and operation. States and local governments were faced with unfunded pension obligations and as a solution, they diverted tax revenues away from the maintenance and growth of infrastructure. The 2008 economic recession occurred and compounded these problems. Budget studies indicated that states needed new policies and strategies to slow down the pace of spending on infrastructure maintenance as the recession started to subside, further exacerbating the infrastructure funding gap.1 This …

The Efficacy Of Accelerating Underprepared Community College Students Using A Corequisite Liberal Arts Mathematics Course, Drew Wilkerson

Theses and Dissertations--Educational Policy Studies and Evaluation

Every year, millions of first-time students enroll in community colleges underprepared for college-level work in mathematics. Typically, these students are referred to a sequence of developmental courses designed to remediate their skills and prepare them for college-level work. Recently, educators and policy makers have questioned the efficacy of these courses, especially since most students assigned to remedial courses never complete the sequence and enroll in college-level courses. Calls to reform developmental mathematics have included changes to how institutions determine whether students are college-ready and the elimination of the remedial course sequences themselves. The corequisite model, in which students enroll in …

Theses and Dissertations--Education Sciences

While total enrollment for Title IV universities in the United States has declined 4 percent from 2013-2018, overall online course enrollment has rapidly increased by 22 percent (National Center for Education Statistics, 2020). Not long ago, distance education had limited diffusion in universities and was considered a tertiary, experimental “add-on” to education (Burnette, 2015). Now, online learning is becoming a transformative power striking profound influence and change on all aspects of higher education (Otte & Benke, 2006). Beaudoin (2015) claims this may be the most crucial change impacting education since the printing press. This study explores the tasks, processes, and …

Investigating How Timing Of Case Study Presentation On Huntington Disease Influences Construction Of Argument Warrant While Learning The Central Dogma Of Molecular Biology, Katherine A. Sharp

Theses and Dissertations--Education Sciences

A common belief among pre-medical and medical students is that biochemistry is not relevant to practicing medicine. Among topics commonly taught in biochemistry, courses include the Central Dogma of Molecular Biology, which is among the most critical science topics taught to medical students by biochemistry educators. Perceived irrelevance among students may be due to common curricular trends in biochemistry education. Many biochemistry courses are found at Research I (R1) universities that teach biochemistry using traditional lectures with little evidence of supporting learning with real-world applications. Instructors commonly assume that students can make realworld connections independently during lecture courses, but it …

The Relationship Between Spatial Ability And The Conservation Of Matter In Middle School, Merryn Cole, Jennifer Wilhelm, Briana Marie-Mcknight Vaught, Corinne Fish, Hailey Fish

A Study Of Language And Its Uses In Flute Performance And Pedagogy, Sarah Tuley

Theses and Dissertations--Music

Various tone colors can be produced on the flute in part by altering the shape of the lips, jaw and tongue movement, and air speed. As these actions are similar to those in the production of speech, flutists and flute teachers often associate aspects of playing with consonants and vowels. However, the shape of the oral cavity can vary depending on the spoken language of the flute-player. By becoming familiar with the pronunciations of different sounds from various languages, the flutist may discover a wider variety of tone colors at his/her disposal. This document will investigate the use of vowels …

A New Model Of Interpreting Modified Strophic Design: Brahms’S Late Viennese Solo Lieder, Yung-Ching Yu

Theses and Dissertations--Music

The study of the interaction between musical and text-based elements in songs has received a great amount of attention in recent years. Although numerous previous researchers have contributed to the study of Brahms’s Lieder, more work remains to explore Brahms’s various compositional techniques of modification to reveal the music-text relationship and performance implications in his strophic songs. Since the majority of Brahms’s modified strophic songs were composed during his later Viennese period (1875–97), this dissertation offers a thorough analysis of Brahms’s late twenty-eight strophic solo Lieder and develops a new formal model to categorize them as one of four types …

Chimurenga Chepfungwa: A Liberated Cultural Curriculum For The Madzimbabwe Singer, Tanyaradzwa Tawengwa

Theses and Dissertations--Music

Chimurenga ChePfungwa is the self-liberation of the mind. Education can either be an instrument for liberation or a tool for colonial indoctrination, brainwashing, and enslavement — the European colonization of Africa in the late-nineteenth century and the continent's epic efforts at self-liberation have amply taught us this.

Chimurenga ChePfungwa calls for the centering of ChiVanhu knowledge systems such as Ngano, Tsumo neNziyo. ChiVanhu encapsulates Madzimbabwe indigenous knowledge systems, cosmologies, and ways of being, and this paper insists on the primacy of these ChiVanhu epistemologies for the construction of knowledge and knowing.

Amagama ayadala. Words create. So much of the language …

Beyond The Notation: Developing Tools To Guide Artistic Decisions Of Performers In The Wind Ensemble, Brent Johnson

Theses and Dissertations--Music

Music is a subjective art form that is enhanced by emotional connection and understanding of the relationship of line and phrasing to both the performer and the audience. Performers and conductors are charged with making artistic decisions about the expressive qualities of a phrase within moments of seeing the notation for the first time. In the development of wind ensembles, there is often a disconnect between the technique and accuracy of a musician’s performance and the emotional connection and understanding required to perform a lyrical melody or phrase within a piece of music. As musicians progress, often the attention is …
