Breeding System And Pollination Of Thermopsis Divaricarpa (Fabaceae: Papilionoideae) In The Southern Rocky Mountains, Roxaneh S. Khorsand, Olufisayo Awolaja Dec 2020

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 …

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 Dec 2020

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 …

The First Generation And Annual Cytogenetic Diversity Of The Simulium Arcticum Malloch Complex (Diptera: Simuliidae) At The Little Blackfoot River, Montana, Gerald F. Shields Dec 2020

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 …

Distribution, Density, And Land Cover Associations Of Wintering Golden Eagles In The Southern Great Plains, Natasia R. Mitchell, Clint W. Boal, Ben R. Skipper Dec 2020

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 …

Harvester Ants Reduce Seed Survivorship In Slickspot Peppergrass, A Rare Mustard Endemic To Idaho, Jennifer A. Brown, Ian C. Robertson Dec 2020

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 …

Leveraging The Inductive Bias Of Large Language Models For Abstract Textual Reasoning, Christopher Michael Rytting Dec 2020

Leveraging The Inductive Bias Of Large Language Models For Abstract Textual Reasoning, Christopher Michael Rytting

Theses and Dissertations

Large natural language models (such as GPT-2 or T5) demonstrate impressive abilities across a range of general NLP tasks. Here, we show that the knowledge embedded in such models provides a useful inductive bias, not just on traditional NLP tasks, but also in the nontraditional task of training a symbolic reasoning engine. We observe that these engines learn quickly and generalize in a natural way that reflects human intuition. For example, training such a system to model block-stacking might naturally generalize to stacking other types of objects because of structure in the real world that has been partially captured by …

Spectral Absorption Coefficient Of Additive Manufacturing Materials, Nicholas J. Wallace, Matthew R. Jones, Nathan B. Crane Dec 2020

Spectral Absorption Coefficient Of Additive Manufacturing Materials, Nicholas J. Wallace, Matthew R. Jones, Nathan B. Crane

Faculty Publications

Active thermography techniques are of interest for quality assurance of additive manufacturing processes. However, accurate measurements of thermophysical properties of materials are required to successfully implement active thermography. In particular, the spectral absorption coefficient of materials commonly used in additive manufacturing must be known to accurately predict the spatial distribution of thermal energy generated from absorption of power emitted by a laser or pulsed flash lamp. Accurate measurements of these optical properties are also needed to develop greater understanding of additive manufacturing processes that rely on radiative heat transfer to fuse powders. This paper presents spectral absorption coefficient measurements and …

A Water Budget And Solute Flux Budget For Waimea River Watershed, Kauai, Hi, U.S.A., Joseph Harold Tolworthy Dec 2020

A Water Budget And Solute Flux Budget For Waimea River Watershed, Kauai, Hi, U.S.A., Joseph Harold Tolworthy

Theses and Dissertations

Waimea Canyon is a deep V-shaped canyon on the island of Kauai, Hawaii in which the Waimea River and its tributaries flow. The shape and size of the canyon are noteworthy and unusual compared to its contemporary canyons on the Hawaiian Islands which are usually U-shaped or flat bottomed. This could be because there is significantly more physical erosion in Waimea Canyon compared to others. A water budget was created using ArcGIS Pro and data from the University of Hawaii’s rainfall and evapotranspiration atlases, as well as from the United States Geological Survey’s stream gage data. A mass flux was …

Reciprocal Empathy: Reversing Antipathy Towards Immigrants In Emotion And Votes, Amanda Gach Dec 2020

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 …

Asian Values And Democratic Viability: A Study Of The Effects Of Political Values On Thai Support For Democracy, Marisa Gonzalez-Mabbutt Dec 2020

Asian Values And Democratic Viability: A Study Of The Effects Of Political Values On Thai Support For Democracy, Marisa Gonzalez-Mabbutt

Undergraduate Honors Theses

Despite research found in the World Values Survey which indicates high global support for democracy, certain regions of the world have struggled to solidify or even introduce democratic institutions. Existing explanations such as the Asian Values Theory show mixed results that political culture in Asian countries decreases support for democracy. These studies also fail to look at country-specific political cultures within countries like Thailand, where national values play a distinct role in the political arena and could affect democratic support. Moreover, previous research has not disaggregated how competing values at the national, regional, and global levels can affect support for …

Biological Pretreatment Of Biomass For Enhanced Biogas Production, Skylar F. Van Horne Dec 2020

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 …

Scavenging Of Animal Carcasses By Gumaga Nigricula (Sericostomatidae, Trichoptera), An Apparent Herbivore, Stephanie M. Carlson, Pablo Rodriguez-Lozano, Hana Moidu, Robert A. Leidy Dec 2020

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 …

A Descriptive Study Of Male Victims Of Sexual Assault Seen For A Sexual Assault Forensic Medical Examination, Madeleine Prince Dec 2020

A Descriptive Study Of Male Victims Of Sexual Assault Seen For A Sexual Assault Forensic Medical Examination, Madeleine Prince

Undergraduate Honors Theses

Ten percent of all victims who report a sexual assault (SA) are male (Department of Justice, 2013), yet there has been little research on their experiences. Further study on the unique characteristics of male SA victims is warranted. The purpose of this study is to explore, identify, and analyze variables of male SA victims who received a SA forensic medical examination (SAFME), and identify implications and areas for future research. Data from the SAFME charts were entered into the Statistical Package for the Social Sciences (SPSS) version 25. Male victims were compared to female victims from the same data set. …

Agnew, Abc, And Richard Nixon's War On Television, Dale L. Cressman Phd Dec 2020

Agnew, Abc, And Richard Nixon's War On Television, Dale L. Cressman Phd

Faculty Publications

Less than a year into the presidency of Richard Nixon, Vice President Spiro Agnew launched a series of attacks on television journalists, accusing them of being biased and having too much power to determine what news millions of Americans watched on their televisions. Because the government licensed and regulated their stations, the networks considered Agnew's statements, and other White House criticisms, to be threats. As the smallest, most vulnerable network, ABC found itself at a confluence of relationships with the administration: It employed both Nixon's favorite and least favorite anchors, as well as a highly placed executive who lent sympathy …

Agency, Atonement, And Psychological Theories Of Change: A Latter-Day Saint Christian Perspective, Richard N. Williams, Edwin E. Gantt Dec 2020

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 …

Help Thou My Unbelief: Exploring The Secular Sources Of Our Clients' Doubts, Edwin E. Gantt, Madeline R. Christensen, Jacob D. Tubbs Dec 2020

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 …

Naturalism, Theism, And The Risks Of Professional Values Imposition In Psychotherapy With Theistic Clients, Jefrey S. Reber Dec 2020

Naturalism, Theism, And The Risks Of Professional Values Imposition In Psychotherapy With Theistic Clients, Jefrey S. Reber

Issues in Religion and Psychotherapy

The codes of ethics guiding the work of counselors and psychotherapists state that ethical practitioners pursue training in areas where they are at risk of imposing values. While training in the potential imposition of personal values is pervasive, training in the potential imposition of professional values is rare. Naturalism, the guiding worldview of science and psychology excludes theism, which is the guiding worldview of many people. Consequently, naturalism is a professional value that may be imposed on theistic clients in psychotherapy. The exclusion of theism from psychology and psychotherapy along with the naturalization of theistic experiences and concepts and the …

An Examination Of Motivation Types And Their Influence On English Proficiency For Current High School Students In South Korean, Euiyong Jung Dec 2020

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 …

Root Cause Analysis And Classification Of Single Point Failures In Designs Applying Triple Modular Redundancy In Sram Fpgas, James D. Swift Dec 2020

Root Cause Analysis And Classification Of Single Point Failures In Designs Applying Triple Modular Redundancy In Sram Fpgas, James D. Swift

Theses and Dissertations

Radiation effects encountered in space or aviation environments can affect the configuration bits in Field Programmable Gate Arrays (FPGA) causing errors in FPGA output. One method of increasing FPGA reliability in radiation environments includes adding redundant logic to mask errors and allow time for repair. Despite the redundancy added with triple modular redundancy (TMR) and configuration scrubbing there exist some configuration bits that individually affect multiple TMR domains causing errors in FPGA output. A new tool called DeBit is introduced that identifies hardware resources associated with a single bit failure. This tool identifies a novel failure mode involving global routing …

A Study Of Fremont Snake Valley Black-On-Gray Ceramics From Sites In Northern Utah And The Parowan Valley, Stephanie K.Y. Abo Dec 2020

A Study Of Fremont Snake Valley Black-On-Gray Ceramics From Sites In Northern Utah And The Parowan Valley, Stephanie K.Y. Abo

Theses and Dissertations

Archaeologists widely argue that Fremont potters from the Parowan Valley, in southwestern Utah, manufactured Snake Valley pottery. For my thesis, I examined Snake Valley Black-on-gray rim sherds using neutron activation analysis, oxidation analysis, metric data, and statistical methods. I compared my results on Snake Valley Black-on-gray sherds from three archaeological sites within the Parowan Valley (Paragonah, Parowan, and Evans Mound) to my results on Snake Valley Black-on-gray sherds recovered from three archaeological sites over 250 kilometers to the north (South Temple, Block 49, and Wolf Village). I argue that the Snake Valley Black-on-gray ceramics from the northern sites are tradewares …

Blast-Induced Liquefaction And Downdrag Development On A Micropile Foundation, Cameron Mark Lusvardi Dec 2020

Blast-Induced Liquefaction And Downdrag Development On A Micropile Foundation, Cameron Mark Lusvardi

Theses and Dissertations

Frequently, deep foundations extend through potentially liquefiable soils. When liquefaction occurs in cohesionless soils surrounding a deep foundation, the skin-friction in the liquefied layer is compromised. After cyclical forces suspend and pore pressures dissipate, effective stress rebuilds and the liquefied soil consolidates. When the settlement of the soil exceeds the downward movement of the foundation, downdrag develops. To investigate the loss and redevelopment of skin-friction, strain was measured on an instrumented micropile during a blast-induced liquefaction test in Mirabello, Italy. The soil profile where the micropile was installed consisted of clay to a depth of 6m underlain by a medium …

The Impact Of Calendering On The Electronic Conductivity Heterogenity Of Lithium-Ion Electrode Films, Emilee Elizabeth Hunter Dec 2020

The Impact Of Calendering On The Electronic Conductivity Heterogenity Of Lithium-Ion Electrode Films, Emilee Elizabeth Hunter

Theses and Dissertations

Advancements in Li-ion batteries are needed especially for the development of electric vehicles and stationary energy storage. Prior research has shown mesoscale variations in electrode electronic conductive properties, which can cause capacity loss and uneven electrochemical behavior of Li-ion batteries. A micro-four-line probe (μ4LP) was used to measure electronic conductivity and contact resistance over mm-length scales in that prior work. This work describes improvements to overcome the challenge of unreliable surface contact between theμ4LP and the sample. Ultimately a second generation flexible probe called the micro-radial-surface probe (μ4LP) was designed and produced. The test fixture was also optimized to obtain …

Experienced Esl Teachers' Attitudes Towards Using Phonetic Symbols In Teaching English Pronunciation To Adult Esl Students, Oxana Kodirova Dec 2020

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 …
