Robustness Of Baryon Acoustic Oscillation Constraints For Early-Universe Modifications Of Λcdm Cosmology, J. L. Bernal, Tristan L. Smith, K. K. Boddy, M. Kamionkowski

Physics & Astronomy Faculty Works

Baryon acoustic oscillations (BAO) provide a robust standard ruler and can be used to constrain the expansion history of the Universe at low redshift. Standard BAO analyses return a model-independent measurement of the expansion rate and the comoving angular diameter distance as a function of redshift, normalized by the sound horizon at radiation drag. However, this methodology relies on anisotropic distance distortions of a fixed, precomputed template (obtained in a given fiducial cosmology) in order to fit the observations. Therefore, it may be possible that extensions to the consensus ΛCDM add contributions to the BAO feature that cannot be captured …

Destabilizing Effects On A Classic Tri-Trophic Oyster Reef Cascade, Virginia R. Schweiss, Chet F. Rakocinski

Faculty Publications

How interactions among multiple predators affect the stability of trophic cascades is a topic of special ecological interest. To examine factors affecting the stability of the classic tri-trophic oyster reef cascade within a different context, configurations of three predators, including the Gulf toadfish, Gulf stone crab, and oystershell mud crab, were manipulated together with either oyster shell or limestone gravel substrate within a multiple predator effects (MPE) experiment. Additionally, a complimentary set of trait-mediated-indirect interaction (TMII) experiments examined the inhibition of oyster consumption relative to mud-crab size and top predator identity in the absence of other cues and factors. The …

Publications

Radiation belt electrons have a complicated relationship with geomagnetic activity. We select electron measurements from 7 years of DEMETER and 6 years of Van Allen Probes data during geomagnetic storms to conduct statistical analysis focusing on the correlation between electron flux and Dst index. We report, for the first time, an upper limit of electron fluxes observed by both satellites throughout the inner and outer belts across a wide energy range from ∼100s keV to multi-MeV. The upper flux limit is determined at different L's and energies, for example, 1.9 × 107/cm2-s-sr-MeV at 470 keV at L = 1.5 and …

Condition Rating Prediction Using An Interactive Deterioration Model Development Package, Minwoo Chang, Mitchell S. Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents an advanced method to determine explanatory variables required for developing deterioration models without the interference of human bias. Although a stationary set of explanatory variables is ideal for long-term monitoring and asset management, the penalty regression results vary annually due to the innate bias in the inspection data. In this study, weighting factors were introduced to consider the inspection data collected for several years, and the most stationary set was identified. To manage the substantial amount of inspection data effectively, we proposed a software package referred to as the Deterioration Model Development Package (DMDP). The objective of …

An Examination Of Motivation Types And Their Influence On English Proficiency For Current High School Students In South Korean, Euiyong Jung

Theses and Dissertations

Despite huge investments in national English language policies, few South Koreans develop communicable English proficiency. Yet, English language proficiency for all secondary and college students continues to be the goal of these policies (Moodie & Nam, 2015; Ahn, 2015). One of the fundamental reasons for the lack of communicable English proficiency was based on the social phenomenon, called 'hakbuljueui', or academic elitism, in Korea (Kim. T.-Y., 2006) whereby students seem to be instrumentally motivated to learn English only to pass the College Scholastic Ability Test (CSAT), and gain admission to elite Universities (Kim, T.-Y., 2006; Kim, K., 2016). The current …

Monitored Freedom: Swing Rhythm In The Jazz Arrangements Of Roland Dyens, Milton Mermikides

Soundboard Scholar

This paper provides an analysis of jazz swing in the work of classical guitarist and composer Roland Dyens. Drawing on Dyens’s published and recorded arrangements of jazz standards, I study both his notation and his performance of swing, starting with a preliminary study of his collection Night and Day and proceeding to a detailed analysis of Nuages—his notated arrangement and four recorded performances. To provide context for Dyens’s stylistic referents, I analyze Django Reinhardt’s 1940 ensemble performance of Nuages. Throughout the discussion, I utilize digital audio analysis and models of microtiming to reveal Dyens’s sophisticated understanding and execution …

Sensuous Knitting: Making Practice That (Re)Members Ecological Entanglement, Sarah Manion

Masters Theses

Conceptualizing the climate crisis as a system of broken relationships calls for a broader understanding of entangled ecological interrelationality. Developing deep and effective responses relies on a stamina for complexity grounded in a recognition and acknowledgement of the way ecological entanglements are revealed to us. Within this frame, practice may provide unique opportunity for the development and promotion of this attuned awareness. To explore this possibility, the personal practice of sensuous knitting is used in this thesis as a way to demonstrate the intersections between intellectual modes of understanding and embodied forms of knowing. Using elements of autoethnographic narration of …

Mobility Justice And Social Capital In Strawberry Mansion And Kensington, Philadelphia Pa, Rebecca Fruehwald

Masters Theses

This thesis explores the theoretical and practical relationship between mobility justice and social capital. A literature review establishes the theoretical relationship through an overview of history and policy. The relationship is then explored through a case study of Strawberry Mansion and Kensington neighborhoods in Philadelphia. These sections are then connected by considering how they are both impacted by the larger system of capitalism. The real-world example of gentrification is given for how all these elements interact and affect each other, and the practical relationship between mobility justice and social capital is established.

Exploring Multimedia Storytelling As A Novel Tool To Inspire Americans To Participate In Wildlife Conservation, Megan Brief

Masters Theses

Human and nonhuman animal lives are intimately entangled. In the age of the Anthropocene, it is imperative to reexamine our proximity and kinship with nature. Human-wildlife conflict can evolve into coexistence through conservation efforts marked by creativity and compassion. To inspire conservation action among North American audiences, we must enact novel ways of disseminating scientifically technical concepts. Multimedia storytelling can encourage equitable involvement among lay participants in conservation spaces. When inclusive of Indigenous knowledges, and conscious of damage narratives, such innovative stories can empathetically communicate wildlife degradation and injustices, as well as animate vulnerable human and nonhuman communities.

Growing Quelites In The City: Exploration On Memory And Food Sovereignty In Mexico City, Paola Valeria Ramirez Ensastiga

Masters Theses

In Mexico, as in the world, the number of people living in urban areas is increasing. In addition, urbanization directly generates a fragmentation of the natural habitat and causes the loss of biodiversity. Native edible crops are also being threatened by a constant decline in biodiversity, causing negative ecological, economic and even cultural impact. Until now, the main guardians of the edible biodiversity have been indigenous peoples. Several authors agree that the way in which indigeous people relate to nature may shed some light on how to face the ecological and climate crisis that we are experiencing today. I argue …

Advances In The Understanding Of Auxin Signaling Through Indirect Mechanisms, Ryan Joseph Emenecker

Arts & Sciences Graduate Student Theses and Dissertations

The plant hormone auxin is remarkable in its capacity to seemingly regulate all plant growth and developmental processes. Because of this, plants have evolved numerous mechanisms to allow for specific responses to auxin dependent on tissue type and developmental stage. Despite the importance of this specificity, we understand very little with respect to the molecular mechanisms underlying it. In this work, we examine two mechanisms used by plants to modulate auxin response across different tissues. First, we describe our finding that auxin interactions with another plant hormone, abscisic acid, is used as a mechanism to regulate auxin responsiveness in the …

Timbre-Based Composition For The Guitar: A Non-Guitarist’S Approach To Mapping And Notation, Jason Noble, Steve Cowan

Soundboard Scholar

Composing for the guitar can be intimidating for non-guitarists, but their fresh perspectives can uncover new ways of thinking about music for the instrument. This paper discusses timbre-based composition, an approach to writing for guitar that may be more intuitive for non-guitarist composers than traditional polyphonic composition. The rich palette of timbres available on the guitar, including pitched and nonpitched sounds, is conceived as primary compositional material. Issues of notation and mapping are addressed, focusing on three categories of mappings: (i) physical mapping from notational symbols onto physical objects, such as parts of the guitar; (ii) analogical mapping from …
