Since the industrial revolution, work and leisure have largely been considered opposing domains. A growing number of organizations, however, enable and/or promote blending leisure activities into the workplace. Similarly, several conceptualizations across different disciplines examine how work and leisure can coexist. These different conceptualizations have yielded a rich but fragmented theoretical account of work–leisure blending. To address this problem, we provide a comprehensive theoretical integration of multiple literature streams where research has explored work–leisure blending. Further, we develop a tripartite dimensional framework designed to elucidate the central dimensions of work–leisure blending (i.e., segmentation– integration, unstructured–structured, and independent–interactive) undergirding this phenomenon. …
State Anxiety Moderates The Association Between Motivations And Excessive Smartphone Use, Xi Shen, Hai-Zhen Wang, Detlef H. Rost, James Gaskin, Jin-Liang Wang
State Anxiety Moderates The Association Between Motivations And Excessive Smartphone Use, Xi Shen, Hai-Zhen Wang, Detlef H. Rost, James Gaskin, Jin-Liang Wang
Faculty Publications
Excessive smartphone use has recently attracted researchers’ attention. Previous studies have suggested that state anxiety and motivations are important predictors of excessive smartphone use. However, few studies have investigated how motivations and state anxiety interact with each other, and the subsequent impact on excessive smartphone use. In the current study, based on the Compensatory Internet Use theory, we analyzed the moderating role of state anxiety on the relationship between two types of motivations (i.e. entertainment and social interaction) and excessive smartphone use. Using the Smartphone Addiction Scale for College Students (SAS-C), Smartphone Usage Motivation Scale and State Anxiety Scale (S-Anxiety), …
Migrating Genes: Using Adna And Archaeological Data To Explain Migration In The Casas Grandes Region Of Northern Mexico, Meradeth Snow, Michael T. Searcy
Migrating Genes: Using Adna And Archaeological Data To Explain Migration In The Casas Grandes Region Of Northern Mexico, Meradeth Snow, Michael T. Searcy
Faculty Publications
Migration as an archaeological topic has addressed huge distances, such as the colonization of the Americas, as well as smaller regions, such as the peopling of specific sites. The use of genetics as a medium to enhance our understanding of population movement can be an asset. There are potential pitfalls, however, such as the misrepresentation of DNA ranging across the landscape without human vectors or motivations. Genetic data must be interpreted through the lens of all available data from the site and surrounding region in order to understand how it its into the potential for human migration. These ideas will …
Breeding System And Pollination Of Thermopsis Divaricarpa (Fabaceae: Papilionoideae) In The Southern Rocky Mountains, Roxaneh S. Khorsand, Olufisayo Awolaja
Breeding System And Pollination Of Thermopsis Divaricarpa (Fabaceae: Papilionoideae) In The Southern Rocky Mountains, Roxaneh S. Khorsand, Olufisayo Awolaja
Western North American Naturalist
Thermopsis divaricarpa (Fabaceae) is a common wildflower in the montane zone of the Colorado Rocky Mountains, but its reproductive ecology is still largely unknown. Montane meadows are recognized for their relatively high species richness and important ecosystem services. Thus, knowledge of the reproductive ecology of T. divaricarpa is useful when assessing community-level responses to climate change in the montane zone of the Rockies. We investigated the phenology, breeding system, and pollination of this species in the southern Rocky Mountains of Colorado. Our results suggest that T. divaricarpa flowers from early June to mid-July, exhibits a facultative xenogamous breeding system, and …
Harvester Ants Reduce Seed Survivorship In Slickspot Peppergrass, A Rare Mustard Endemic To Idaho, Jennifer A. Brown, Ian C. Robertson
Harvester Ants Reduce Seed Survivorship In Slickspot Peppergrass, A Rare Mustard Endemic To Idaho, Jennifer A. Brown, Ian C. Robertson
Western North American Naturalist
Seed predation can significantly reduce the reproductive success of individual plants and their populations. The consequences of seed predation often are most pronounced for rare plant species, in which loss of seeds can have a disproportionate effect on populations. The present study examined the effects of seed predation by Owyhee harvester ants (Pogonomyrmex salinus) on seed survivorship in slickspot peppergrass (Lepidium papilliferum), a rare mustard endemic to sagebrush-steppe habitat in southwestern Idaho. Within sagebrush-steppe, L. papilliferum is restricted to microsites known as “slick spots”—shallow depressions of soil characterized by distinct clay layers and surface water retention …
The First Generation And Annual Cytogenetic Diversity Of The Simulium Arcticum Malloch Complex (Diptera: Simuliidae) At The Little Blackfoot River, Montana, Gerald F. Shields
The First Generation And Annual Cytogenetic Diversity Of The Simulium Arcticum Malloch Complex (Diptera: Simuliidae) At The Little Blackfoot River, Montana, Gerald F. Shields
Western North American Naturalist
I made six extensive collections of black fly larvae at the Little Blackfoot River (LBFR) in western Montana at roughly 2-week intervals from 25 March to 2 June 2019 to describe larval size-class frequencies and cytogenetic diversity of the first spring generation. Frequencies of seven size classes, pupae, and pupal exuviae are given, though no larvae with egg bursters (first-instar larvae) were observed. Therefore, the earliest instars were missed. Sex chromosomes of 562 larvae of this first generation were compared to those of 1260 other larvae previously analyzed from 10 dates (2003 to 2012) to determine whether sex chromosome frequencies …
Native Fish Loss In A Transition-Zone Stream Following Century-Long Habitat Alterations And Nonnative Species Introductions, Matthew R. Haworth, Kevin R. Bestgen, Edward R. Kluender, William H. Keeley, Donald R. D'Amico, F. Boyd Wright
Native Fish Loss In A Transition-Zone Stream Following Century-Long Habitat Alterations And Nonnative Species Introductions, Matthew R. Haworth, Kevin R. Bestgen, Edward R. Kluender, William H. Keeley, Donald R. D'Amico, F. Boyd Wright
Western North American Naturalist
Habitat destruction, hydrologic alteration, and nonnative species introductions have greatly altered the composition of North American stream fish assemblages. In the western United States, intermediate-elevation transition-zone stream reaches––those located between higher-elevation mountain and lower-elevation plains areas––historically supported native fish assemblages that included sensitive species and peripheral or isolated populations of more widespread taxa. We compiled historical records and conducted sampling to examine changes to the fish assemblage in the transition-zone reach of South Boulder Creek, Colorado, USA. Because human development of transition zones altered stream and riparian ecosystems prior to sampling, we developed a historical timeline of human activities to …
Distribution, Density, And Land Cover Associations Of Wintering Golden Eagles In The Southern Great Plains, Natasia R. Mitchell, Clint W. Boal, Ben R. Skipper
Distribution, Density, And Land Cover Associations Of Wintering Golden Eagles In The Southern Great Plains, Natasia R. Mitchell, Clint W. Boal, Ben R. Skipper
Western North American Naturalist
In addition to its resident Golden Eagles (Aquila chrysaetos), the Southern Great Plains of North America receives an influx of migrant Golden Eagles each winter. However, little current or quantitative information is available regarding eagle presence or the species’ land cover associations across the region. During the winters of 2014/2015 and 2015/2016, we surveyed Golden Eagles along 51 approximately 55-km-long road survey transects within a 136,800-km2 area of the Southern Great Plains of eastern New Mexico and the panhandles of Texas and Oklahoma. Our goal was to estimate the winter density of Golden Eagles in the region …
Reciprocal Empathy: Reversing Antipathy Towards Immigrants In Emotion And Votes, Amanda Gach
Reciprocal Empathy: Reversing Antipathy Towards Immigrants In Emotion And Votes, Amanda Gach
Undergraduate Honors Theses
The topic of immigration politics has gained traction in recent years as surges of immigrants are introduced to new homes—often with a long road of integration into the host country ahead. As a result, debates emerged on how to effectively “humanize” members of these outgroups – which include immigrants and refugees alike—while also being able to forge lasting cooperation between these ethnic groups allowing for peaceful integration. Previous attempts to achieve this goal have used various forms of visual and sensory media to generate empathy towards these outgroup members. These approaches have proven to be ineffective when not met with …

Scavenging Of Animal Carcasses By Gumaga Nigricula (Sericostomatidae, Trichoptera), An Apparent Herbivore, Stephanie M. Carlson, Pablo Rodriguez-Lozano, Hana Moidu, Robert A. Leidy
Western North American Naturalist
Caddisflies within the genus Gumaga are generally considered shredders (i.e., consumers of leaf litter) or grazers (i.e., consumers of algae). We report on observations of Gumaga nigricula scavenging animal carcasses within and adjacent to isolated pools along intermittent reaches of Coyote Creek, Santa Clara County, California, USA. In particular, during the summer of 2018, we observed G. nigricula scavenging fish carcasses within isolated pools as well as bits of flesh from the bones of a black-tailed deer (Odocoileus hemionus columbianus) deposited on the stream bank. To the best of our knowledge, our observations represent the first published record …
Biological Pretreatment Of Biomass For Enhanced Biogas Production, Skylar F. Van Horne
Biological Pretreatment Of Biomass For Enhanced Biogas Production, Skylar F. Van Horne
Undergraduate Honors Theses
The biogas output efficiency of controlled anaerobic digestion (AD) can be enhanced by several different pretreatment methods to produce renewable energy. According to the literature, there are pros and cons to each pretreatment method. Biological pretreatment provides environmentally safe and renewable means for enhancing biodegradability and net energy output. Current research has yet to reliably demonstrate the ability of bacterial strains, such as Caldicellulosiruptor bescii (C. bescii), to digest common waste substrates in efficient ways. Novel methods in key intermediate molecular quantification and alkalinity tracking are used here to explore C. bescii’s ability to digest lignocellulosic material in …
Help Thou My Unbelief: Exploring The Secular Sources Of Our Clients' Doubts, Edwin E. Gantt, Madeline R. Christensen, Jacob D. Tubbs
Help Thou My Unbelief: Exploring The Secular Sources Of Our Clients' Doubts, Edwin E. Gantt, Madeline R. Christensen, Jacob D. Tubbs
Issues in Religion and Psychotherapy
Issues of faith and doubt are often at the heart of religious clients’ psychological and emotional suffering. As such, they are a topic of genuine therapeutic interest. Latter-day Saint therapists have a unique responsibility to help our religious clients work through their psychological concerns, as well as help them address their religious doubts when relevant in the therapeutic setting. We argue that many of the concerns fueling client faith crises spring from taken-for-granted assumptions absorbed from our larger secular culture. Further, these assumptions are radically different from – indeed, typically antithetical to – the premises upon many of our fundamental …
Agency, Atonement, And Psychological Theories Of Change: A Latter-Day Saint Christian Perspective, Richard N. Williams, Edwin E. Gantt
Agency, Atonement, And Psychological Theories Of Change: A Latter-Day Saint Christian Perspective, Richard N. Williams, Edwin E. Gantt
Issues in Religion and Psychotherapy
This paper interrogates the relationship of the hard determinism inherent in the theories and models currently on offer in mainstream psychology and the current trends in psychotherapeutic approaches. It foregrounds the seeming contradiction between the emphasis placed on mastering and incorporating discipline-specific knowledge – which clearly assumes scientism and hard determinism – and the emphasis placed on practitioners to develop a coherent theory of change as part of their approach to effective clinical practice. We argue that hard determinism and strategies for facilitating genuine therapeutic change and transformation are incompatible where there is no clear, coherent view of human beings …

In addition, the data include char size, shape, surface and internal temperature and discrete measurements of porosity, total surface area, pore size distribution and …
Experienced Esl Teachers' Attitudes Towards Using Phonetic Symbols In Teaching English Pronunciation To Adult Esl Students, Oxana Kodirova
Experienced Esl Teachers' Attitudes Towards Using Phonetic Symbols In Teaching English Pronunciation To Adult Esl Students, Oxana Kodirova
Theses and Dissertations
Different opinions exist about the use of phonetic alphabet symbols in teaching English pronunciation to second language learners. Some authors and researchers believe phonetic symbols can benefit students in many ways; others consider this tool hardly recommendable. However, little empirical research has been done to find out what ESL teachers think about the use of this linguistic tool. Thus, via an online survey this study sought to identify ESL teachers' attitudes towards the use of phonetic symbols in teaching ESL pronunciation. A total of 120 teachers took the survey and most of them were experienced in teaching pronunciation to adult …
Identification Of Genes That Determine Fitness, Virulence, And Disease Outcomes In Mastitis Associated Eschericia Coli, Michael Andrew Olson
Identification Of Genes That Determine Fitness, Virulence, And Disease Outcomes In Mastitis Associated Eschericia Coli, Michael Andrew Olson
Theses and Dissertations
Escherichia coli is an incredibly diverse group of bacteria that consist of both commensal and pathogenic strains that cause disease in a wide variety of tissues in many different animals. The current dogma, based on years of extensive molecular and genetic studies, is that individual strains have adapted to specific environments through acquisition of specific genes or come from lineages that are particularly suited to a unique tissue or host. However, mastitis-associated E. coli (MAEC) have thus far resisted such descriptions. The fitness and virulence factors of MAEC are poorly understood and molecular tools are rarely applied. This dissertation reports …

Late Quaternary Voles From Persistence Cave, Black Hills, South Dakota, Christopher N. Jass, Jim I. Mead, Sandra L. Swift
Western North American Naturalist
Excavations at Persistence Cave (Black Hills, SD), produced a large sample of Quaternary microfauna including a diverse assemblage of arvicoline rodents. Identifiable lower first molars (n = 367) include specimens referred to heather vole (Phenacomys sp.), muskrat (Ondatra sp.), southern bog lemming (Synaptomys cooperi), red-backed vole (Myodes sp.), sagebrush vole (Lemmiscus curtatus), prairie vole (Microtus ochrogaster), and a form of meadow vole (Microtus sp.). Direct radiocarbon dating of specimens of Lemmiscus curtatus is consistent with previous records from the Nelson–Wittenberg Site and indicates that sagebrush voles inhabited …
A Noninvasive Genetic Technique Using Guano For Identification Of Corynorhinus Townsendii (Townsend’S Big-Eared Bat) Maternity Roosts, Kelly E. Williams, Richard E. Sherwin, Kaci K. Vandalen, Antoinette J. Piaggio
A Noninvasive Genetic Technique Using Guano For Identification Of Corynorhinus Townsendii (Townsend’S Big-Eared Bat) Maternity Roosts, Kelly E. Williams, Richard E. Sherwin, Kaci K. Vandalen, Antoinette J. Piaggio
Western North American Naturalist
The use of DNA from fecal samples can allow for a better understanding of the ecology of a species without capturing and handling the animals. This is particularly useful for cryptic and elusive animals, such as bats. Being able to identify critical habitat, such as maternity roosts, for bat species in areas where they depend on abandoned mines that could be slated for closure is necessary to enact appropriate protections for such roosts. In particular, Corynorhinus townsendii commonly uses abandoned mines for maternity roosts. Further, maternity roosts are difficult to identify through visual surveys when only one or a few …
On The Accepted Name Of The Paria River Breadroot, Pediomelum Pariense (S.L. Welsh & N.D. Atwood) J.W. Grimes, Ashley N. Egan
On The Accepted Name Of The Paria River Breadroot, Pediomelum Pariense (S.L. Welsh & N.D. Atwood) J.W. Grimes, Ashley N. Egan
Western North American Naturalist
Two groups independently and seemingly simultaneously published the new combination of Pediomelum pariense, the Paria River breadroot. Both names were published in the second-quarter issues of separate journals in 1986. Same issue dates have led to confusion over which name takes precedence and is thus accepted. However, one issue was delayed in printing. Evidence is provided herein for acceptance of Pediomelum pariense (S.L. Welsh & N.D. Atwood) J.W. Grimes over Pediomelum pariense (S.L. Welsh & N.D. Atwood) S.L. Welsh & N.D. Atwood.
Dos grupos publicaron de forma independiente y aparentemente simultánea la nueva combinación de Pediomelum pariense, el …
Instrumentation And Application Of Image-Charge Detection Of Electrospray-Charged Microparticles And Microdroplets, Jiuzhi Gao
Theses and Dissertations
Image-charge detection is emerging as an important tool to analyze heavy and heterogeneous samples because of its unique advantages in measuring highly charged microparticles. Conventional image-charge detection instruments include at least three fundamental components: an ionization source, an aerodynamic particle delivery system, and an image-charge detector. Here I report research efforts that investigated the mechanisms of image-charge detection and proposed some instrumental developments of these components to suit specific research purposes. In Chapter 2, I report an investigation of the electrospray ionization (ESI) mechanism based on an observation that a certain portion of charged particles generated with an ESI source …
Methods For Generative Adversarial Output Enhancement, Michael B. Brodie
Methods For Generative Adversarial Output Enhancement, Michael B. Brodie
Theses and Dissertations
Generative Adversarial Networks (GAN) learn to synthesize novel samples for a given data distribution. While GANs can train on diverse data of various modalities, the most successful use cases to date apply GANs to computer vision tasks. Despite significant advances in training algorithms and network architectures, GANs still struggle to consistently generate high-quality outputs after training. We present a series of papers that improve GAN output inference qualitatively and quantitatively. The first chapter, Alpha Model Domination, addresses a related subfield of Multiple Choice Learning, which -- like GANs -- aims to generate diverse sets of outputs. The next chapter, CoachGAN, …
Antimicrobial Peptide Development: From Massively Parallel Peptide Sequencing To Bioinformatic Motif Identification, Alexander K. Erikson
Antimicrobial Peptide Development: From Massively Parallel Peptide Sequencing To Bioinformatic Motif Identification, Alexander K. Erikson
Theses and Dissertations
The isolation, purification, and clinical deployment of antibiotics is one of the major drivers of decrease in morbidity and mortality from infectious bacteria in the 20th century. The rapid, ubiquitous deployment of antibiotics encouraged swift development and distribution of antibiotic resistance. New, novel techniques, technologies, and ultimately therapeutic antimicrobial compounds will be required to counter the rise of antibiotic resistant microbes. Historically, mimicking naturally occurring compounds has been the most fruitful method for discovering new antibiotics; unsurprisingly, many recent efforts have focused on expanding the cultivation and detection of previously unknown microbes and compounds, respectively. Other techniques explore developing compounds …
A Morphological Phylogeny Of Odonatoptera: Examining Missing Data In A Group With A Lot Of "Naturally" Missing Data, Robert James Erickson
A Morphological Phylogeny Of Odonatoptera: Examining Missing Data In A Group With A Lot Of "Naturally" Missing Data, Robert James Erickson
Theses and Dissertations
Odonatopera exhibit a wide diversity of morphologies for an ancient group of winged insects. A morphological matrix of 463 characters is compiled for 347 extant and fossil representatives used in parsimony analyses, implemented in TNT, to document arrangements of taxonomic groups above the family level. Missing data and other challenges approaches implemented and interpretation of the results. We employ a novel approach to testing monophyly relative to quantities of missing data for each taxon. Phylogenetic reconstructions recover patterns of monophyly and trends based on missing data. We discuss the implications of our findings on missing data as well as limitations …
Structures And Characteristics Of Macromolecular Interactions In Gas Phase Using Fourier-Transform Ion Cyclotron Resonance Mass Spectrometry, Jiewen Shen
Theses and Dissertations
This dissertation investigates non-covalent macromolecular chemistry using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) based techniques. The included studies reveal the impact of molecular structure on conformation and binding energetics. Supramolecules that might be too heavy to be dissociated in single collision-induced dissociation (CID) were dissociated using sustained off-resonance collision induced dissociation (SORI-CID) techniques. Relative binding energies and thresholds were evaluated for various macromolecular host-guest systems. Besides the non-covalent binding energies, conformation characterization was undertaken by a novel method to determine collision cross sectional areas using FTICR (CRAFTI, and multi-CRAFTI), initially developed by the Dearden lab. The systems chosen …
A Rapid Spectrophotometric Assay For Quantifying Seed Coat Saponins In Quinoa, Sydney Diver Szabo
A Rapid Spectrophotometric Assay For Quantifying Seed Coat Saponins In Quinoa, Sydney Diver Szabo
Theses and Dissertations
Background and objectives: The commonly used afrosimetric foam-height method for quantifying saponins in quinoa is rapid but imprecise. A rapid UV/Vis method, utilizing the Liebermann-Burchard (LB) color reaction, was compared to the foam method across a range of saponin levels in washed and unwashed seed. Findings: A 6 min UV/Vis method provided greater precision and accuracy than the afrosimetric method at the lower saponin levels found in washed quinoa. The afrosimetric method did not differentiate saponin levels below 0.6 mg/mL but allows for useful relative comparisons of saponin content in unwashed quinoa where the foam height is large. Conclusions: The …
Damsel In Distress Or Princess In Power? Traditional Masculinity And Femininity In Young Adult Novelizations Of Cinderella And The Effects On Agency, Rylee Carling
Theses and Dissertations
Retellings of classic fairy tales have become increasingly popular in the past decade, but little research has been done on the novelizations written for a young adult (YA) audience. Critical multicultural analysis determining the effect of race, gender, disability, and more has been completed for both original fairy tale retellings and fairy tale retellings for children, but scholars have neglected popular YA novelizations. This study aims to determine how traditional masculinity and femininity affect agency in both male and female characters in YA novelizations of Cinderella. To examine the role of traditional masculinity and femininity in young adult novelizations of …
