Landscape Ecology Influence On Population Dynamics And Gene Flow: A Muskrat’S Tale, Ayla A. Morehouse

Theses and Dissertations

Understanding movement patterns across a landscape is an essential tool for wildlife managers to understand and predict population dynamics, interactions, and susceptibility to disease and environmental changes. Part of this is due to population spatial synchrony being driven by three primary factors: dispersal, the “Moran Effect”, and trophic interactions. We seek to understand if dispersal may play a larger role in population synchrony and, if so, what landscape features may hinder the movement of muskrats (Ondatra zibethicus), a small semiaquatic mammal that relies on ditches and shallow wetlands for habitat and local movement. In this study we genotyped eleven microsatellite …

An Examination Of The Effects Of Body Mapping Instruction On Singers’ Static Standing Posture And Posture While Singing, Amanda Moreno

Theses and Dissertations

Physical posture is one of the fundamental aspects of vocal technique, and voice pedagogues suggest that effective alignment is necessary for healthy vocal production. Body Mapping (BMG) is a somatic method that focuses on the understanding and correction of errors in a person’s body map to facilitate effective movement for musical activity. Because this method has balance, physical alignment, and posture as foundational, it may be an effective way to begin to instruct students. This study investigated whether the use of the BMG method, which teaches posture through movement, scientific pictures, and anatomical models, would result in a significant difference …

Phylogenetic Relationships Of Noctuoid Moths With An Examination Of Complex Characteristics, Melissa Sisson

Theses and Dissertations

The tribe Noctuini comprise over 520 species; many are economically important species that impact human agriculture. Despite their diversity and relevance, relationships of the Noctuini have been difficult to resolve. There are extensive morphological revisions of these taxa (e.g., Agrotis, Euxoa); however, there are no studies that focus exclusively on the phylogenetic relationships of the Noctuini. Currently, the Noctuini are separated into two subtribes, the Agrotina and Noctuina, which each are further subdivided into two subgenera. In this study, we tested previous classification schemes using three loci. We sampled three outgroup taxa and 54 noctuine species that represent the majority …

In Search Of The Public Interest, Jodi L. Short

Faculty Scholarship

“Public interest” standards in statutory delegations to agencies represent the greatest hopes and the darkest fears of the U.S. administrative state. On the one hand, the public interest standard provides a vessel for agencies to infuse policymaking with the moral and ethical commitments of the community. On the other hand, regulation in the public interest opens the door to the arbitrary exercise of tyrannical state power. Despite the lofty aspirations and ominous warnings about regulation in the public interest, little is known about how agencies actually decide what is in the public interest when charged by statute to do so. …

Factors Associated With New Hospital Nurses' Self-Efficacy In Providing Palliative End-Of-Life Care, Penny Marie Brriese

Theses and Dissertations

Introduction: Self-efficacy is defined as confidence in one’s competence; the ability to successfully accomplish tasks and achieve favorable outcomes (Bandura, 1997). Many nurses today say they feel their undergraduate education was inadequate for them to feel competent to provide palliative and EOL patient care. (Chiplaskey, 2016; Scherlin & Quinn, 2016; Zheng et al., 2018).). Inadequate EOL preparation also results in nurses experiencing distress, death anxiety, burnout, feeling overwhelmed and leaving practice within just a few years (Friedman et al., 2011; Gaw, 2012; Kovner et al., 2006; Parry, 2008; Silverstein, 2017, November 28; Suzuki et al., 2008; Wilson & Kirshbaum, 2013). …

Measuring Local Policy To Advance Fair Housing And Climate Goals Through A Comprehensive Assessment Of Land Use Entitlements, Moira O’Neill, Eric Biber, Nicholas Marantz

Faculty Scholarship

California’s legislature has passed several laws that intervene in local land-use regulation in order to increase desperately needed housing production—particularly affordable housing production. Some of these new laws expand local reporting requirements concerning zoning and planning laws, and the application of those laws apply to proposed housing development. This emphasis on measurement requires the state to develop a housing data strategy to support both enforcement of existing law and effective policymaking in the future. Our Comprehensive Assessment of Land Use Entitlements Study (CALES) predates, but aligns with and supports, this state-led effort to improve local reporting. For the cities that …
