The Impact Of Faculty Status And Gender On Employee Well-Being In Academic Libraries, Quinn Galbraith, Leanna Fry, Melissa Garrison

Faculty Publications

This study measures job satisfaction, personal fulfillment, work/life balance, and stress levels of male and female librarians. Researchers surveyed 719 librarians at ARL institutions that either offer faculty status and tenure or offer neither. Females at libraries offering faculty status indicated poor work/life balance and high levels of stress compared to male colleagues and female librarians without faculty status; however, their reported job satisfaction was similar. Possible implications of the results are discussed.

Species Identification Of The Stylohyoid Bone For North American Artiodactyls, Thomas A. Hale

All Master's Theses

Zooarchaeologists cannot identify mammal species by their stylohyoid bones. Current trends in zooarchaeological research stress the need for rigorous and accessible identification methodology. I examined the stylohyoids of 15 hooved mammals: cattle, bison, domestic sheep, bighorn sheep, Dall sheep, mountain goat, domestic goat, elk, caribou, white-tailed deer, mule deer, moose, pronghorn antelope, domestic pig, and horse. Objectives included documenting how to side the stylohyoid (left or right), and producing species identification criteria based on large samples. A total of 325 samples were measured from eight repositories. Written descriptions, photographs, and success ratios for metrics and distinct traits are included for …

The Life Cycle Of Dams: An Analysis Of Policy Change On The Rogue River, Oregon, Wendy Mcdermott

All Master's Theses

Every river system contains a unique set of attributes including biophysical characteristics, human created infrastructure, and stakeholder user groups. This thesis utilizes Lowry’s (2003) “Theoretical Framework for Policy Changes” to provide an analysis of fundamental policy change that occurred on the Rogue River in southwest Oregon through a comparative case study of the removal of two dams: Savage Rapids Dam (SRD) and the Gold Ray Dam (GRD). Fundamental change occurs when political receptivity is high and physical complexity is low. Political receptivity characterizes how decisions are made and physical complexity refers to how complicated implementing the decision may be. Application …

Race, Immigration, And A Change Of Heart: A History Of The San Francisco Chinatown, Sarah Littman

All Master's Theses

This thesis examines how the 1906 San Francisco earthquake and subsequent fire affected the local Chinatown and Chinese immigration as a whole. It focuses on communities from the Pearl River Delta of southern China, their motivations for emigration, the industries they found employment in, and the racially charged legislation they had to contend with. By 1902 the Chinese Exclusion Act forbid Chinese immigration indefinitely, but the fire of 1906 destroyed the local City Hall which housed all of the city’s immigration records. Chinese immigrants exploited the opportunity, applying for more documentation than they needed and distributing the extras to those …

An Economic Approach To Modeling Archaeological Settlement Patterns In Central Idaho, Anthony J. Saunders

All Master's Theses

Archaeologists can gain a better understanding of subsistence strategies by analyzing the net advantage of exploiting certain resources over others across a large area with the use of Geographic Information Systems (GIS) and application of economic. GIS modeling is a powerful tool used by archaeologists to catalog and analyze site information in a spatial context. Economic models interpret human behavior in terms of cost and benefit. Little archaeological research has been done in central Idaho. This thesis develops economic models of hunting, gathering and fishing for the Frank Church River of No Return Wilderness (FC-RONRW). This research builds upon previous …

Defining Biodiversity: A Local Assessment Of The Tahuayo River, Peru Using Self-Directed Photography, Rozsika D. Steele

All Master's Theses

The Área de Conservación Regional Comunal Tamshiyacu Tahuayo (ACRCTT), located in Loreto, Peru, protects 420,000 hectares of the Amazon basin. In 2009, the ACRCTT received formal government recognition after three decades of advocacy and conservation work by resident communities. Local resource users who live a subsistence lifestyle possess sophisticated Traditional Ecological Knowledge (TEK) that can be used to identify which constituents of biodiversity are culturally relevant. This information can help resource managers develop an operational definition of biodiversity. Self-directed photography is a research method that allows participants the opportunity to direct data collection and empowers them to visually communicate their …

Effect Of Quantum Dots, Novel Biological Imaging Agents, In Liver Cells In Vitro, Utshaha Maharjan

All Master's Theses

The use of Quantum dots (QDs) coated with polymer and functionalized with carboxylic acid groups in medical applications are explored. Their water solubility and exceptional stability in aqueous environments make them potentially useful for such applications as imaging and ligand attachments. However, there are concerns regarding the toxic effects of QDs and the minimal dose that can be used without producing any detrimental effects to organisms. In this study, QDs coated with the amphiphilic polymer coating tri-n-octylphosphine oxide and poly (maleic anhydride-alt-1-tetradecene (TOPO-PMAT)) which is functionalized with carboxylic acid groups were used to investigate their toxic effect in mouse liver …

Activity Patterns, Home Range, And Microhabitat Selection Of A Terrestrial Turtle (Rhinoclemmys Rubida Perixantha) In A Tropical Dry Forest, Taggert G. Butterfield

All Master's Theses

Turtles are in trouble worldwide, with nearly half recognized by the International Union for Conservation of Nature (IUCN) as needing special protection. The Eurasian pond and Neotropical wood turtles of the family Geoemydidae are the most diverse turtles and comprise ¼ of all turtle species yet basic information on their natural history is lacking. Moreover, seasonal tropical dry forest (SDTF), where many geoemydids exist, is considered the most endangered ecosystem in the world. We investigated the activity patterns, home range size, and microhabitat selection of the Mexican Spotted Wood Turtle (Rhinoclemmys rubida perixantha) in its SDTF habitat by …

Applications Of Computational Geometry And Computer Vision, Joseph Lemley

All Master's Theses

Recent advances in machine learning research promise to bring us closer to the original goals of artificial intelligence. Spurred by recent innovations in low-cost, specialized hardware and incremental refinements in machine learning algorithms, machine learning is revolutionizing entire industries. Perhaps the biggest beneficiary of this progress has been the field of computer vision. Within the domains of computational geometry and computer vision are two problems: Finding large, interesting holes in high dimensional data, and locating and automatically classifying facial features from images. State of the art methods for facial feature classification are compared and new methods for finding empty hyper-rectangles …

Play In Immature Tibetan Macaques (Macaca Thibetana): Location, Use Of Play Signals, And Play Bout Termination At Mt. Huangshan, China, Kaitlin R. Wright

All Master's Theses

In this study, I examined the relationship between play behaviors, play location, the frequency of selected play signals, and play bout termination in Tibetan macaques (Macaca thibetana) during immature social play. I gathered video data at the Valley of the Wild Monkeys, Mt. Huangshan, China, and focused on 21 juvenile and infant macaques (zero to five years of age). I used an all occurrence sampling method to score play behaviors and play signals with an ethogram. I hypothesized that play groups would use play signals in functionally appropriate ways based on the location of the play bout, the …

Comparison Of Chimpanzee (Pan Troglodytes) Behavior On Tour And Non-Tour Days At Chimpanzee Sanctuary Northwest, Allison A. Farley

All Master's Theses

In this study, I investigated the potential effect of a visitor program on captive chimpanzees’ (Pan troglodytes) behaviors at Chimpanzee Sanctuary Northwest (CSNW) in Cle Elum, Washington. I used focal animal sampling to score behaviors from an ethogram of affiliative, aggressive and abnormal chimpanzee behaviors, as well as foraging and vigilance. During each sample, I recorded the focal’s location within the enclosure and whether he or she was situated in locations that would be in view of visitors (present or not). I analyzed 720 minutes of data from each of the seven CSNW chimpanzees. I tested the hypothesis …

Testing The Forage Preference Of The American Pika (Ochotona Princeps) For Use In Connectivity Corridors In The Washington Cascades, Carly Wickhem, Kristina Ernest

All Master's Theses

One of the aims of the Snoqualmie Pass East Project (SPEP) in the Cascades of central Washington is to construct nearly 30 wildlife crossing structures along a 15-mile stretch of Interstate-90. American pikas (Ochotona princeps) are being monitored for the SPEP because they have specific habitat requirements and are poor dispersers. Making the crossing structures “pika-friendly” will encourage these low-mobility animals to use the structures. Recent research suggests that the presence of quality vegetation may help pika populations avoid declines and extirpations, so planting suitable forage within and adjacent to the crossings will be essential. During the summer …

Resolving Gnetum Evolutionary History, Angela Mcfadden

All Master's Theses

Gnetum are non-flowering seed plants of the tropics, indigenous to South America, Africa, and Asia. This group of about 40 species is fascinating to botanists because it shares distinctive morphological characteristics with flowering plants, such as broad leaves, woody stems, and flower-like strobili. There are still questions surrounding the relationships within the genus of Gnetum. With that in mind, I focused my work on generating phylogenetic hypotheses, using two molecular data sets: a concatenation of over 60 different chloroplast genes (66,815 base pairs), and the whole chloroplast genome (128,772 base pairs). This allowed me to compare the two phylogenies …

The Use Of A Visual Aid To Facilitate Transitional Periods For Children With Autism Spectrum Disorder, Stevi Barrio

All Master's Theses

Transitioning is described as moving from one activity or place to another and has been often recognized as an event that can provoke problem behaviors in children diagnosed with autism spectrum disorder (Sainato et al., 1987). Past research has concentrated on facilitating transitions by using both functional behavior assessments and visual aids. A type of functional behavior assessment is the Questions About Behavioral Function, which is a measurement system designed to determine the function of a given behavior and the environmental stimuli that surround that behavior. This questionnaire rates how often the individual engages in the behavior for situations …

Seasonal Microhabitat Use Of Young-Of-The-Year Bull Trout, Salvelinus Confluentus, In A Drought Year, Ashton Brook Bunce

All Master's Theses

This study examined the microhabitat use of young-of-the-year (YOY) bull trout, Salvelinus confluentus, throughout the summer and fall of 2015 in Gold Creek, a third order Cascade Mountain stream near Snoqualmie Pass, WA. It is crucial to understand YOY habitat requirements, as this life stage is highly vulnerable to fluctuations in streamflow and various ecological risks associated with their dispersal. Previous research has demonstrated that YOY salmonids often occupy stream margins where they are sheltered from these kinds of threats. However, in the face of climate change, Pacific Northwest streams are more susceptible to decreased summer streamflows and elevated, irregular …

Confirmation Of Emx2 Protein Binding Partners, Cody Gillman

All Master's Theses

The neocortex is a structure within mammalian brains that processes sensory input from eyes, ears, and touch receptors and mediates the conscious use of skeletal muscles. The processing of information related to each of these types of functions is localized within discrete areas of the neocortex, which are separated by sharp borders. Proper development of these functional areas is regulated during embryogenesis by several transcription factors that are expressed in distinct gradients across the progenitor layer of the neocortex, the ventricular zone. Despite the vast amount of progress that has been made in describing how these transcription factors impact the …

High Diversity Of Trypanosoma Cruzi Discrete Typing Units Circulating In Triatoma In Western Mexico, Uyen T. Nguyen

All Master's Theses

Chagas disease is caused by the protozoan parasite Trypanosoma cruzi, which is transmitted to domestic and sylvatic mammals via the feces of hematophagous hemiptera of the subfamily Triatominae (Reduviidae). Trypanosoma cruzi is found only in the Americas and displays remarkable genetic diversity. Seven discrete typing units (DTUs) are currently recognized (TcI–TcVI and TcBat). In Jalisco, Mexico, where Chagas disease has a high prevalence rate, TcI has historically been the only DTU reported. This study focused on the molecular identification of T. cruzi DTUs circulating in Triatoma near the Estación de Biología Chamela, on the southwest coast of Jalisco, Mexico. …

The Hormonal Regulation Of The Claudin Genes In The Ovary, Sean Gadson, April Binder, Kenneth Korach, Katherine Hamilton

All Master's Theses

The ovary is a dynamic organ that responds to many hormonal signals. When these hormonal signals are disrupted, ovarian dysfunction can occur. One such example is Polycystic Ovarian Syndrome (PCOS). PCOS patients suffer from high levels of testosterone. Excess testosterone may misregulate genes in the ovary and disrupt ovarian function. The Claudin (Cldn) 3 and Cldn11 genes have been shown to be regulated by androgens in the testis, while studies in ovarian cancer cells suggests a coregulatory mechanism for the expressions of Cldn3 and Cldn4 in the ovary. The objective of this study was to characterize the hormonal …

Breaking The Silence: The Veterinarian’S Duty To Report, Martine Lachance

Animal Sentience

Animals, like children and disabled elders, are not only the subjects of abuse, but they are unable to report and protect themselves from it. Veterinarians, like human physicians, are often the ones to become aware of the abuse and the only ones in a position to report it when their human clients are unwilling to do so. This creates a conflict between professional confidentiality to the client and the duty to protect the victim and facilitate prosecution when the law has been broken. I accordingly recommend that veterinarian associations make reporting of abuse mandatory.

Project Summary And Developmental Programs For Ishew, Lindsey Lequia, Dallas Rohraff

Honors Projects

On a seemingly normal day during my study abroad in Ghana, we noticed that the sun was shining in a sky that seemed to have no clouds. We were taking a trip to visit the water source of a community that contained nearly 1,000 people. Although it amazed us to think that that many people were fetching water each day from a river, we understood that others do not have access to the purified, city water that we are fortunate to have at home. When we pulled into the community, the reality of their lifestyle contrasted with what we had …

The Role Of Personality And Gender In Performance In Science And Engineering, Rossina B. Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Science, Technology, Engineering, and Mathematics (STEM) student success is important to universities across the nation. Existing studies have examined standardized exams and high school GPA as predictors of student success; fewer studies have examined the role of personality. The present study examined whether STEM students have different personalities than the general population, whether population-level gender differences in personality were evident among STEM students, and if personality predicts academic success. The Big Five Inventory (BFI) measuring personality was given to a diverse population of students in introductory physics and calculus classes, as well as developmental mathematics (non-science track) classes, at a …

Accuracy In The Badminton Short Serve: A Methodological And Kinematic Study, Shayne Marc Vial

Theses: Doctorates and Masters

In sports, accuracy is an essential component of actions such passing, shooting, and aiming. Executing a movement or action that requires a high degree of accuracy is a critical determinant of success in many individual and team sports. Each sport has different methods for evaluating accuracy, however an overarching goal is to determine whether an object hits its target, or assess the distance by which it misses. However, in some sports accuracy is not readily measureable because an object might not reach a target, i.e. the object is intercepted, or it collides with another object or a person, or an …

Human Oocytes And Embryos Viewed By Time-Lapse Videography, And The Development Of An Embryo Deselection Model, Yanhe Liu

Theses: Doctorates and Masters

Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse observation of human embryos is gaining increasing popularity due to the more detailed morphokinetic information obtained plus uninterrupted culture conditions. The morphokinetic information enables the use of quantitative timings in developmental milestones of embryos and qualitative measures of abnormal biological events, to assist embryo selection/deselection. This project aimed to identify current limitations in the use of such measures and …

An Algorithm For Extracting The Ppg Baseline Drift In Real-Time, Tuan Ngoc Nguyen

Theses: Doctorates and Masters

Photoplethysmography is an optical technique for measuring the perfusion of blood in skin and tissue arterial vessels. Due to its simplicity, accessibility and abundance of information on an individual’s cardiovascular system, it has been a pervasive topic of research within recent years. With these benefits however there are many challenges concerning the processing and conditioning of the signal in order to allow information to be extracted. One such challenge is removing the baseline drift of the signal, which is caused by respiratory rate, muscle tremor and physiological changes within the body as a response to various stimuli.

Over the years …

Interfacing Of Neuromorphic Vision, Auditory And Olfactory Sensors With Digital Neuromorphic Circuits, Anup Vanarse

Theses: Doctorates and Masters

The conventional Von Neumann architecture imposes strict constraints on the development of intelligent adaptive systems. The requirements of substantial computing power to process and analyse complex data make such an approach impractical to be used in implementing smart systems.

Neuromorphic engineering has produced promising results in applications such as electronic sensing, networking architectures and complex data processing. This interdisciplinary field takes inspiration from neurobiological architecture and emulates these characteristics using analogue Very Large Scale Integration (VLSI). The unconventional approach of exploiting the non-linear current characteristics of transistors has aided in the development of low-power adaptive systems that can be implemented …

The Serum Concentrations Of Anti-Mullerian Hormone (Amh), Thyroid-Stimulating Hormone (Tsh), Free Triiodothyronine (Ft3) And Free Thyroxine (Ft4) During Early Pregnancy, Kristina Hamilton

Theses: Doctorates and Masters

The first trimester of pregnancy is a dynamic time of change involving the implantation and development of the fetus, together with a wide range of related endocrine changes arising from the ovary and feto-placental unit, as well as other changes in maternal and fetal physiology. The present longitudinal study has investigated two main areas of endocrinology in circulating maternal serum from positive pregnancy test to the detection of a fetal heartbeat, namely (i) AMH and (ii) thyroid function. Women attending Fertility North and conceiving during fertility investigation or treatment underwent phlebotomy twice weekly and AMH, TSH, fT3 and fT4 levels …

A Resiliency Perspective Of The Lived Experience Of Parenting Infants And Young Children With Cystic Fibrosis In The Context Of Early Lung Disease Surveillance, Cindy Branch-Smith

Theses: Doctorates and Masters

Scientific and technological advances over the past few decades have contributed to an exponential increase in life expectancy for infants born with cystic fibrosis (CF), which can cause fatal lung disease. There has been a paradigmatic shift from reactive treatment towards early disease detection and aggressive intervention of paediatric CF. Previous research has investigated parents’ experiences of the diagnosis phase and later life stages such as adolescence and transition to adulthood. Less is understood about the experience of parenting infants and young children with CF, and no research addresses this during early surveillance for CF lung disease. Early surveillance is …

Small-Scale Biogeographic Patterns Of Benthic Bacterial And Ciliate Communities In The Saline Ponds Of Lake Macleod, North-Western Australia, Christopher Kavazos

Theses: Doctorates and Masters

This biogeographical thesis tests for the presence of taxa-area and distance-decay relationships, which are common among macrobionts, in prokaryotic (bacterial) and micro-eukaryotic (ciliate) communities. Microbial biogeographical patterns may be distinct because of the high abundances, diversity and dispersal capabilities of microbes, in comparison to macrobionts. The Northern Ponds of Lake MacLeod, north-western Australia, provide an ideal location to address this topic, because the ponds are effectively hydrogeomorphologically identical, other than in surface area, and biotic histories can be assumed to differ only according to distance of separation. This means that hypotheses concerning species-sorting and neutral processes on microbial assemblages can …

Influence Of Increased Sediment Exposure On Suspension-Feeder Assemblages In A Temperate Seagrass Meadow, Pierre Bouvais

Theses: Doctorates and Masters

The impact of increased sediment exposure on coastal marine ecosystems is one of the most important contemporary environmental issues. Sediment exposure is defined as the concentrations of sediment particles suspended in the water column and the amount of sediment depositing on the seabed. In addition to natural events, such as land erosion, rainfall, and tidal currents, anthropogenic activities such as land use, road building, logging, mining, port maintenance and dredging, contribute to the discharge of a great amount of sediment in the water column. As sessile suspension-feeder assemblages play a critical role in marine ecosystems through their active transfers of …

Predicting The Impact Of Future Climate On Ecologically Important Macroalgae, Charlie Phelps

Theses: Doctorates and Masters

Macroalgae play an important role in coastal reef systems and are often referred to as ecosystem engineers. They serve as primary producers, supporting a diverse range of organisms, and are a sink for atmospheric CO2. Water acidification and ocean warming caused by anthropogenic activities are affecting many marine flora and fauna, potentially impacting the physical and chemical performance of macroalgae and the consumption rates of associated herbivores. Many studies have focused on ocean acidification or ocean warming individually but there is an overall lack of research investigating the combined effects and the ensuing repercussions on consumer-prey relationships.
