Landscape To Local: A Multi-Scale Evaluation Of Voluntary Efforts To Reduce Fragmentation And Enhance Management Of Rangelands For Sage-Grouse, Joseph Tyler Smith

Graduate Student Theses, Dissertations, & Professional Papers

For imperiled species, the hierarchical nature of habitat selection suggests the need for a hierarchical approach to conservation: address threats to persistence operating at broad scales on populations before focusing on the quality of patches or availability of particular resources used by individuals. We apply this approach to conservation and management of habitat for greater sage-grouse (Centrocercus urophasianus) in the eastern portion of their range where cropland conversion continues to fragment sagebrush grasslands. Using locations of active leks in portions of Montana, Wyoming, North Dakota, and South Dakota as spatial indices of populations, we found sage-grouse distribution was highly sensitive …

Extreme Hybrid Growth, Genomic Imprinting, The Large X Effect, And The Drivers Of Speciation In Mammals, Thomas David Brekke

Graduate Student Theses, Dissertations, & Professional Papers

Mammalian hybrids often show abnormal growth, indicating that developmental inviability may play an important role in mammalian speciation. Yet it is unclear if this recurrent phenotype reflects a common genetic basis. Here I describe patterns of hybrid inviability between two closely related species of dwarf hamsters, Phodopus campbelli and P. sungorus. Using genetic crosses, I found extreme parent-of-origin dependent growth in hybrid embryos and placentas. Abnormal growth in hybrid mammals has been empirically linked to genomic imprinting, the parent-specific silencing of a single allele that occurs in many genes involved in regulating embryonic growth. Epigenetic disruptions of genomic imprinting activate …

Mechanisms And Consiqences Of Lysosomal Membrane Permeabilization Following Exposure To Bioactive Particles, Forrest Connell Jessop

Graduate Student Theses, Dissertations, & Professional Papers

Exposure to bioactive environmental particles and engineered nanoparticles are a significant public health concern. Inhalation of bioactive particles can result in chronic inflammation, which drives tissue remodeling and fibrosis. Furthermore, chronic inflammation can increase individual susceptibility to other diseases including cancer and autoimmune diseases. The macrophage is the critical cell in particle clearance following exposure, and is central to the inflammatory responses and tissue remodeling. Phagocytosed bioactive particles within macrophages cause cytotoxicity and activation of the NLRP3 inflammasome, outcomes that are both essential to inflammation and disease development. However, mechanisms that regulate NLRP3 inflammasome activity and cytotoxicity have not fully …

The “Spirit” That Returns To God In Ecclesiastes 12:7, Dana M. Pike

Faculty Publications

Influenced by the Restoration doctrine of premortality, some Latter-day Saints have employed the KJV translation “the spirit” in Ecclesiastes 12:7 to support the doctrine that spirit personages leave their mortal bodies at death. Furthermore, Latter-day Saints have sometimes asserted, again citing Ecclesiastes 12:7, that a premortal spirit being can only “return” to God because it previously came from him. This verse has thus become one of several in the Old Testament that some Latter-day Saints have employed as support for premortal existence, a doctrine that is so important in the broader plan of salvation.

Listener Perceptions Of Simulated Fluent Speech In Nonfluent Aphasia, Tyson G. Harmon, Adam Jacks, Katarina L. Haley, Richard A. Faldowski

Faculty Publications

Background: People with aphasia (PWA) are frequently perceived less favorably by listeners than their peers. These perceptions include incorrect assumptions that can prevent successful social interactions. While communication partner training has been shown to improve social outcomes related to the listener (see e.g., Kagan, Black, Duchan, Simmons-Mackie, & Square, 2001), changing the verbal output of PWA may also yield more favorable listener perceptions about the speech, speaker, and their own affective response. We investigated the effects of artificially altered fluency (i.e., simulated fluency) on listeners’ subjective impressions.

Aims: The purpose of the study was to (1) confirm that listeners perceive …

Peer Tutoring In Physical Education: A Review Of Evidence-Based Practices, Kanica Yiep

Cal Poly Humboldt theses and projects

Including students with disabilities in physical education may cause many challenges such as having teachers who are not properly trained to include students with various disabilities. The active nature of the environment and needs of students with disabilities may require extra assistance in addition to having a physical education teacher. Although there are many challenges to include students with disabilities into a general physical education class research demonstrates inclusion is beneficial for students with and without disabilities. The purpose of this paper is to review research on peer tutoring in physical education and to discuss evidence-based practices for implementation of …

The Effect Of Rest Interval Duration On The Volume Completed During A High Intensity Bench Press Exercise, Dennis J. Hernandez

Cal Poly Humboldt theses and projects

Between set rest intervals (RI) are one of the most important variables in resistance training; however, no known research has investigated the effects of RIs greater than 5-min during strength training (>85% of 1RM). The purpose of this research was to examine the effects of three different RIs (2, 5, and 8-minute) on training volume (kg, sets x reps x resistance) and repetition sustainability during a high-intensity bench press exercise (> 85% of 1RM). Fifteen resistance trained males (mean+sd, age = 26+5 yr, height = 161+6 cm, body mass = 79+6 kg, bench press 1RM ratio = 1.39+0.1) completed …

A Comparison Of Simple Global Kinetic Models For Coal Devolatilization With The Cpd Model, Andrew Richards, Thomas H. Fletcher

Faculty Publications

Simulations of coal combustors and gasifiers generally cannot incorporate the complexities of advanced pyrolysis models, and hence there is interest in evaluating simpler models over ranges of temperature and heating rate that are applicable to the furnace of interest. In this paper, six different simple model forms are compared to predictions made by the Chemical Percolation Devolatilization (CPD) model. The model forms included three modified one-step models, a simple two-step model, and two new modified two-step models. These simple model forms were compared over a wide range of heating rates (5000 to 10⁶ K/s) at final temperatures up to …

Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel

Cal Poly Humboldt theses and projects

Wildlife-habitat relationship studies are important for understanding the factors that determine where species occur in space and time. Habitat selection by generalist species should be studied on fine spatial and temporal scales to avoid masking important differences between seasons, localities, or orders of selection. I conducted the first study of habitat use and general ecology of North American porcupines (Erethizon dorsatum) in a coastal dune environment. Specifically, I assessed changes in body mass, home range size, and habitat selection in relation to the potential for seasonal nutritional and survival bottlenecks as reported elsewhere. Although they are considered generalists, …

Evaluating Brandt’S Cormorant (Phalacrocorax Penicillatus) Reproductive Success: Effects Of Parental Care Behaviors And Estimating Individual Chick Survival, Shannon Murphy

Cal Poly Humboldt theses and projects

Variation in reproductive success is widely measured in seabird biology in an effort to indicate changes in the marine environment, or understand basic questions about ecology or conservation of seabirds. When variation in seabird reproductive success is suggested to indicate changes in the marine environment without identifying the proximate causes of such variation, inference is limited to association, and the proximate causes themselves could prove more effective as indicators. My study informs this problem by examining and quantifying proximate causes of variation in reproductive success, at the level of nests and individual chicks.

I used video of Brandt’s Cormorant ( …

Fine-Scale Change Detection Using Unmanned Aircraft Systems (Uas) To Inform Reproductive Biology In Nesting Waterbirds, Sharon Dulava

Cal Poly Humboldt theses and projects

Aerial photographic surveys from manned aircraft are commonly used to estimate the size of bird breeding colonies but are rarely used to evaluate reproductive success. Recent technological advances have spurred interest in the use of unmanned aircraft systems (UAS) for monitoring wildlife. The ability to repeatedly sample and collect imagery at fine-scale spatial and temporal resolutions while minimizing disturbance and safety risks make UAS particularly appealing for monitoring colonial nesting waterbirds. In addition, advances in photogrammetric and GIS software have allowed for more streamlined data processing and analysis. Using UAS imagery collected at Anaho Island National Wildlife Refuge during the …

Molt In Individuals: A Description Of Prealternate Molt Phenology In A Population Of Snowy Plovers In Humboldt County, California, Alexa Dejoannis

Cal Poly Humboldt theses and projects

Molt in birds is an essential physiological process. Intrinsic and extrinsic conditions, such as age, sex, location, or food stress, may cause individual variation in molt phenology. This study describes the timing of prealternate molt in western snowy plovers (Charadrius nivosus nivosus) wintering in Humboldt County, California, USA. Between July 2014 and April 2015, I photographed uniquely marked plovers twice a month and assigned dates of initiation and completion. I modeled sex, age, hatch date, and breeding location as predictors of molt phenology. I observed prealternate molt from October to April, which is earlier than previously described. Males …

Stories Of Smartness And Whiteness In School Pictures And Yearbooks, Eric Ruiz Bybee

Faculty Publications

This article explores the way that discourses of smartness and whiteness are produced and reproduced in schooling. Using an approach grounded in narra- tive research, I explore the convergences and contradictions between my own educational autobiography and the representations of schooling found in my school pictures and yearbooks. In my analysis, I argue that white supremacy played an important role in the construction of my own story of smartness throughout my primary and secondary schooling experiences. I also argue that yearbooks form powerful “artifacts of smartness” (Hatt, 2011, p. 448) that can be used to interpret and interrogate personal experiences …

Recovering With Acquired Apraxia Of Speech: The First 2 Years, Tyson G. Harmon, Katarina L. Haley, Jennifer N. Shafer, Adam Jacks

Faculty Publications

This study was intended to document speech recovery for 1 person with acquired apraxia of speech quantitatively and on the basis of her lived experience. The second author sustained a traumatic brain injury that resulted in acquired apraxia of speech. Over a 2-year period, she documented her recovery through 22 video-recorded monologues. We analyzed these monologues using a combination of auditory perceptual, acoustic, and qualitative methods. Recovery was evident for all quantitative variables examined. For speech sound production, the recovery was most prominent during the first 3 months, but slower improvement was evident for many months. Measures of speaking rate, …

Exploring The Clinical Utility Of Relative Fundamental Frequency As An Objective Measure Of Vocal Hyperfunction, Christopher Dromey, Nelson Roy, Rebecca A. Fetrow, Ray M. Merrill

Faculty Publications

Purpose: Vocal hyperfunction, related to abnormal laryngeal muscle activity, is considered the proximal cause of primary muscle tension dysphonia (pMTD). Relative fundamental frequency (RFF) has been proposed as an objective acoustic marker of vocal hyperfunction. This study examined (a) the ability of RFF to track changes in vocal hyperfunction after treatment for pMTD and (b) the influence of dysphonia severity, among other factors, on the feasibility of RFF computation. Method: RFF calculations and dysphonia severity ratings were derived from pre- and posttreatment recordings from 111 women with pMTD and 20 healthy controls. Three vowel–voiceless consonant–vowel stimuli were analyzed. Results: RFF …

Laryngeal Desiccation Challenge And Nebulized Isotonic Saline In Healthy Male Singers And Nonsingers: Effects On Acoustic, Aerodynamic, And Self-Perceived Effort And Dryness Measures, Christopher Dromey, Kristine Tanner, Robert B. Fujiki, Ray M. Merrill, Whitney Robb, Katherine A. Kendall, J Arden Hopkin, Ron W. Channell, M Preeti Sivasankar

Faculty Publications

Summary: Objectives. This study examined the effects of a laryngeal desiccation challenge and nebulized isotonic saline on voice production in young, healthy male singers and nonsingers. Study design. This is a prospective, double-blind, within-subjects experimental design. Methods. Participants included 10 male university-trained singers and 10 age-matched nonsingers (mean age, 21.8 years; range, 18–26 years) who underwent a 30-minute oral breathing laryngeal desiccation challenge using medical grade dry air (<1% relative humidity) on two occasions in consecutive weeks. After the challenge, participants received either 3 mL or 9 mL of nebulized isotonic saline (0.9% Na+ Cl); order of administration was counterbalanced. Phonation threshold pressure (PTP), the cepstral spectral index of dysphonia (CSID) for sustained vowels and connected speech, and self-perceived vocal effort, mouth dryness, and throat dryness were measured at each recording (baseline, after challenge, and at 5, 35, and 65 minutes after treatment). Results. Self-perceived effort and dryness measures increased (worsened) after desiccation challenge and decreased (improved) after nebulized treatment (P < 0.05). No consistent changes were observed for PTP or CSID over time. Overall, singers demonstrated significantly lower vocal effort and CSID as compared with nonsingers. Conclusions. Young, vocally healthy men may not experience physiologic changes in voice production associated with laryngeal desiccation and nebulized saline treatments; however, self-reported increases in vocal effort which are associated with dryness symptoms might improve with nebulized treatments. Future hydration research should consider age and sex variables

Early Mimbres Households: Exploring The Late Pithouse Period (550–1000 Ad) At The Florida Mountain Site, Michael T. Searcy, Bernard Schriever, Matthew Taliaferro

Faculty Publications

Many studies have explored the household to understand social organization, production, and other dynamics of societies throughout the world. In this work, the approach outlined by Richard Wilk and colleagues is used to investigate households at the Florida Mountain Site, an intermittently occupied Late Pithouse period (550–1000 AD) residential site in the Mimbres Mogollon area of Southwestern New Mexico. Drawing on the similarities of this intermittent residential site to contemporaneous pitstructure sites in the Mimbres area, we suggest that one or more household units occupied the site. Our analysis also supports previous inferences that Mimbres households were integrated into more …

Civil Religion, Nativist Rhetoric, And The Origins Of Washington National Cathedral, Richard Benjamin Crosby

Faculty Publications

Set atop the highest point in the nation's capital, The Washington National Cathedral is the sixth largest cathedral in the world. It has become a central site for the high holy rituals of American civil religion, hosting presidential funerals, National Day of Prayer services, and the tombs of national luminaries. Drawing on archival research, this essay situates the cathedral within a history of religious competition and national tension. The essay concludes that the cathedral's roots lie largely in the fecund rhetorical soil of nineteenth-century nativism, the cultural prejudice that emerged in reaction to Roman Catholicism's remarkable growth during that period. …

Spiritual Modalities: Prayer As Rhetoric And Performance, By William Fitzgerald (Review), Richard Benjamin Crosby

Faculty Publications

Spiritual Modalities is arguably the first major work to take up the high theoretical questions of rhetoric and religion since Burke's Rhetoric of Religion published more than half a century ago. While a number of other studies deal with the relationship between religious discourse and other phenomena, such as politics, social movements, or particular rhetors and periods, Spiritual Modalities makes a strong claim to understand the primeval stuff of prayer's varied and complex discourses. As Burke writes: "we are to be concerned not directly with religion, but with the terminology of religion" (vi). So Fitzgerald is not concerned with prayer …

Development Of A Novel In Vivo Corneal Fibrosis Model In The Dog, K. M. Gronkiewicz, Elizabeth A. Giuliano, K. Kuroki, F. Bunyak, Ajay Sharma, L. B. C. Teixeira, C. W. Hamm, R. R. Mohan

Pharmacy Faculty Articles and Research

The aim of this study was to develop a novel in vivo corneal model of fibrosis in dogs utilizing alkali burn and determine the ability of suberanilohydroxamic acid (SAHA) to inhibit corneal fibrosis using this large animal model. To accomplish this, we used seven research Beagle dogs. An axial corneal alkali burn in dogs was created using 1 N NaOH topically. Six dogs were randomly and equally assigned into 2 groups: A) vehicle (DMSO, 2 μL/mL); B) anti-fibrotic treatment (50 μM SAHA). The degree of corneal opacity, ocular health, and anti-fibrotic effects of SAHA were determined utilizing the Fantes grading …

Reliability Generalization Of The Multigroup Ethnic Identity Measure- Revised (Meim-R), Timothy B. Smith, Hayley Marie Herrington, Erin Feinauer, Derek Griner

Faculty Publications

Individuals’ strength of ethnic identity has been linked with multiple positive indicators, including academic achievement and overall psychological well-being. The measure researchers use most often to assess ethnic identity, the Multigroup Ethnic Identity Measure (MEIM), underwent substantial revision in 2007. To inform scholars investigating ethnic identity, a reliability generalization analysis was performed on data from the revised version (MEIM–R) and compared with data from the original MEIM. Random-effects weighted models evaluated internal consistency coefficients (Cronbach’s alpha). Reliability coefficients for the MEIM–R averaged α = .88 across 37 samples, a statistically significant increase over the average of α = .84 for …

The Lds Church In Taiwan: The First Three Years, John Hilton Iii

Faculty Publications

Located approximately one hundred miles east of continental Asia, the island of Taiwan has a rich and complicated history. The history of Taiwan intersected with the history of The Church of Jesus Christ of Latter-day Saints (LDS) when LDS military personnel were stationed there in 1955. This led to the celebrated date of June 4, 1956, when the ship SS Szechuen carried among its passengers four LDS missionaries. While this would be the first time LDS missionaries would begin proselyting efforts in Taiwan, Christian missionaries had sailed into Taiwan’s harbor centuries previously. The purpose of the present study is to …

Mormon Metaphors Of Restoration: Pathways To Identity And Understanding, Dallin D. Oaks

Faculty Publications

The important role of metaphors in interfaith understanding has received significant attention. The pervasiveness of certain metaphors in the lives of members of a religious community is especially significant when they are incorporated into sacred texts. This would seem to be the case not only for Judaism, Islam, and mainline Christianity, but also for Mormonism, a distinctive branch of Christianity. Officially known as The Church of Jesus Christ of Latter-day Saints (LDS), Mormonism shares some root metaphors with other Christians but differs in important ways in its development and use of these metaphors. In this paper we discuss the journey, …

Absence Of “Joseph Smith” In The Book Of Mormon: Lack Of The Name Letter Effect In Nephite, Lamanite, And Jaredite Names, Bruce L. Brown, Sharon Black, Brad Wilcox, Wendy Baker Smemoe

Faculty Publications

Although some authors of fiction attempt to hide their real names by publishing their work under pseudonyms, the letters and sounds they consciously or subconsciously select for the names of their characters often reveal the author’s true identity. Since 1985, research has explored the name letter effect—the preference people show for the letters and sounds (especially initial sounds) in their own names. This tendency is evident in the highly personal and introspective literature produced in the United States during Joseph Smith’s lifetime by authors such as Nathaniel Hawthorne, Washington Irving, and Edgar Allan Poe. The purpose of this study was …

The Unique Influences Of Parental Divorce And Parental Conflict On Emerging Adults In Romantic Relationships, Scott R. Braithwaite, Reed A. Doxey, Krista Dowdle, Frank D. Fincham

Faculty Publications

Parental divorce and parental conflict influence children across multiple domains, including risk of divorce in their own marriages. However, parental conflict and divorce, both separately and the interaction between the two, have not often been studied in premarital relationships, especially when considering possible mechanisms mediating these effects. In a large sample of emerging adults (N = 353), we show that when the most plausible mediating mechanisms are simultaneously considered, only relational commitment mediates the influence of parental conflict on outcomes. Parental conflict in the absence of divorce was associated with less commitment and, in turn, less relationship satisfaction and stability …

What Mediates The Relationship Between Religious Service Attendance And Aspects Of Well-Being?, Scott A. Baldwin, Patrick R. Steffen, Kevin S. Masters

Faculty Publications

Religious service attendance predicts increased well-being across a number of studies. It is not clear, however, whether this relationship is due to religious factors such as intrinsic religiosity or due to nonreligious factors such as social support or socially desirable responding. The purpose of the present study was to examine the relationship between religious service attendance and well-being while simultaneously examining intrinsic religiosity, social support, and socially desirable responding as potential mediators of the relationship. A sample of 855 participants (71 % female, average age 19.5) completed questionnaires assessing religiosity, social support, socially desirable responding, and well-being. Path models were …

Optimization-Based Path Planning For Separation Assurance On Small Unmanned Aircraft, Matthew Duffield, Andrew Ning, Timothy Mclain

Faculty Publications

This paper presents a time-based path planning optimizer for separation assurance for unmanned aircraft systems (UAS). Given Automatic Dependent Surveillance-Broadcast (ADS-B) as a sensor, intruder information such as position, velocity, and identification information is available at ranges on the order of 50 nautical miles. Such long-range intruder detection facilitates path planning for separation assurance, but also poses computational challenges. The time-based path optimizer presented in this paper provides a path-planning method that takes advantage of long-range ADS-B information and addresses the associated challenges. It is capable of long-range path planning and, due to the convex formulation, is computationally efficient enough …

Parameterized Vertical-Axis Wind Turbine Wake Model Using Cfd Vorticity Data, Andrew Ning, Eric Tingey

Faculty Publications

In order to analyze or optimize a wind farm layout, reduced-order wake models are often used to estimate the interactions between turbines. While many such models exist for horizontal-axis wind turbines, for vertical-axis wind turbines (VAWTs) a simple parametric wake model does not exist. Using computational fluid dynamic (CFD) simulations we computed vorticity in a VAWT wake, and parameterized the data based on normalized downstream positions, tip-speed ratio, and solidity to predict a normalized wake velocity deficit. When compared to CFD, which takes about a day to run one simulation, the reduced-order model predicts the velocity deficit at any location …

Airline Safety Improvement Through Experience With Near-Misses: A Cautionary Tale, Peter Madsen, Robin L. Dillon, Catherine H. Tinsley

Faculty Publications

In recent years, the U.S. commercial airline industry has achieved unprecedented levels of safety, with the statistical risk associated with U.S. commercial aviation falling to 0.003 fatalities per 100 million passengers. But decades of research on organizational learning show that success often breeds complacency and failure inspires improvement. With accidents as rare events, can the airline industry continue safety advancements? This question is complicated by the complex system in which the industry operates where chance combinations of multiple factors contribute to what are largely probabilistic (rather than deterministic) outcomes. Thus, some apparent successes are realized because of good fortune rather …
