Implications Of Research On Expertise For Curriculum And Pedagogy, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Instruction on problem solving in particular domains typically relies on explanations from experts about their strategies. However, research indicates that such self-reports often are incomplete or inaccurate (e.g., Chao & Salvendy, 1994; Cooke & Breedin, 1994). This article evaluates research on experts’ cognition, the accuracy of experts’ self-reports, and the efficacy of instruction based on experts’ self-reports. Analysis of this evidence indicates that experts’ free recall of strategies introduces errors and omissions into instructional materials that hinder student success. In contrast, when experts engage in structured knowledge elicitation techniques (e.g., cognitive task analysis), the resultant instruction is more effective. Based …

Cranberry Girdler, Erin W. Hodgson, Alan H. Roe

All Current Publications

Cranberry girdler, Chrysoteuchia topiaria, can be found throughout the U.S., but is particularly damaging to turfgrass seed production areas in the Pacific Northwest. This insect was first detected in northern and northeastern Utah during the early 1980’s. Larvae prefer cool-season grasses, such as Kentucky bluegrass, bentgrass and fine-leaf fescues. In addition to causing significant damage to turfgrass, it is recorded as a pest of other grasses, cranberry, Douglas fir, and true firs.

Sod Webworms, Erin W. Hodgson, Alan H. Roe

All Current Publications

The term “sod webworm” refers to an insect complex of more than twenty different grass-infesting species. Adult sod webworms are pyralid moths, but are more commonly referred to as “snout moths” because their mouthparts are projected forward (Fig. 1). Sod webworms are distributed through the U.S., and at least seven different species occur in Utah (Table 1).

Environmental Assessment Bird Damage Management In The Wyoming Wildlife Services Program, United States Department Of Agriculture, Animal And Plant Health Inspection Service, Wildlife Services

All U.S. Government Documents (Utah Regional Depository)

The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Wildlife Services (WS), U.S. Fish and Wildlife Service (USFWS), Federal Aviation Administration (FAA); Wyoming Game and Fish Department (WGFD), and Wyoming Department of Health (WDH) propose to continue the current bird damage management program in Wyoming. WS, USFWS, FAA, WGFD, and WDH use an adaptive integrated wildlife damage management (IWDM) approach to reduce bird damage to property, agricultural resources, natural resources, and to protect human health and safety. In addition, under the current program, the USFWS would continue to issue depredation permits based on need and …

A Historic Perspective: The Response Of Breeding Passerines To Rangeland Alteration In Rich County, Utah, Lindsay J. Brown

Biology

Shrub-dominated ecosystems on private lands are important rangeland resources through much of the western U.S., including Rich County, Utah. Because of its important role in livestock production, this shrubsteppe ecosystem has been exposed to a variety of sagebrush removal methods. Little is known about the relative effects of chemical, mechanical, or burn treatments on breeding passerine communities. Furthermore, most studies address only short-term effects. We studied breeding passerine communities and vegetation on 17 untreated sites and 49 range sites treated between 1962 and 2004 to examine the effects of treatment type and treatment age. The sagebrush treatments produced considerable changes …

Effects Of Environmental Conditions And Insect Life Stages On Performance Of Entomopathogenic Nematodes For Suppression Of Plum Curculio, Conotrachelus Nenuphar (Coleoptera: Curculionidae), In Northern Utah, Hong Geun Kim

Biology

In a series of field and laboratory experiments, I tested two entomopathogenic nematode species, two nematode concentrations, and three life stages of the economically damaging insect pest, Contrachelus nenuphar, to support the development of a biological control program for this pest in northern Utah. Two entomopathogenic nematodes, Heterorhabditis bacteriophora and Steinernema feltiae, were tested for their virulence. The population of H. bacteriophora tested was collected from soil infested with plum curculio in Brigham City, UT in 2002. The S. feltiae population was obtained from a commercial source. In temperature bioassays, the two nematodes species exhibited different thermal ranges. …

The Role Of Individual-Level Behavior: From Safe Passage To Self-Organization, Bertrand H. Lemasson

Biology

A considerable amount of research in fisheries exists to assess and predict the success rate of fish attempting to navigate through artificial barriers in their environment. Such barriers typically include dams, culverts, power plants, and pumping stations. This dissertation contributes to fisheries science, and general ecology, by determining how individual-level behavior affects the movement decisions of solitary fish and how simple inter-individual interactions can generate complex forms of collective behavior. The current research improves our ability to model small-scale movement patterns, such as those expected within the artificial restrictions of a water diversion facility, and provides insight into the communication …

A Water-Efficient Landscape: Public Lands Center, Montrose, Co, Marcus Pulsipher

Undergraduate Honors Capstone Projects

The problem of water-wasting landscapes is prevalent throughout the western United States. For decades western settlers struggled to turn their arid lands into the more familiar settings of lush vegetation found in their native New England and Western Europe. This mind set has been passed down through generations and has transformed into the basis of the current western water crisis (Brundin and Pearson 2001). Only in the last few decades has this mentality been challenged and we've seen the emergence of several water-efficient landscape models. Through careful application of water-efficient landscape principles, western communities can greatly extend the life of …

Common Nutritional Deficiencies In The Three Richest Versus The Poorest Countries In The World: Why Are They Similar Or Different?, Ginger Ann Bailey

Undergraduate Honors Capstone Projects

Over one billion people suffer from nutritional deficiencies, and they reside in both the poorest and the richest countries in the world. What needs to be determined is if the deficiencies are similar or different, and most importantly why. By learning what nutritional deficits exist in these countries and why they occur, we are then able to create appropriate interventions in order to improve the nutritional status of populations worldwide.

Child Sexual Abuse: Development Of Psychiatric Disorders And Interventions, Toshikazu Kuroda

Undergraduate Honors Capstone Projects

Child sexual abuse has become a serious social concern due to the recent report of its higher incidence rate than commonly believed. This form of child abuse has been proposed to bring about adverse effects on children's development since more than one century ago. However, research over past decades reveals that effects of sexual abuse are extremely complex and diverse. Particularly, there appear to be many unclear factors increasing the probability for the development of psychiatric disorders in sexually abused children. The present paper investigated how child sexual abuse creates diversity over the course of the victims' development from multiple …

Sustainable Materials In High-End Residential Interior Design, Sarah Platt

Undergraduate Honors Capstone Projects

Our most contemporary architecture is the biggest culprit contributing to global warming. We see the results globally, from one corner to the other affecting everything in between: Phillipine forests are clear-cut for plywood used to construct Japanese offices; homes in Southern California are framed with old-growth lumber from Washington and powered by burning coal strip-mined from Navajo sacred lands in Arizona. Point being, the destructive power of poor design isn't limited to the end-user, if affects everyone. Additionally, not only are these buildings forever altering the landscape they are placed upon and everywhere their resources were pulled from, but everything …

Infant Feeding Practices: History, Nutrient Needs, Assessment Of Nutriture, And Special Concerns, Katy Lynn Bodily

Undergraduate Honors Capstone Projects

Ideas regarding infant feeding practices have changed drastically over the past 100 years. Research discovered the composition of human milk, followed by the invention of human milk substitute (HMS). These discoveries lead to many changes in the way people feed infants. The macro and micronutrient needs of infants have been determined, and are used to develop ideal feeding practices for infants. There are many choices available for feeding infants including human milk, HMS, and solid foods. There are many guidelines available that provided suggestions on what to feed an infant, and at what age. Assessing the adequacy on infant feeding …

Can't, Shouldn't, And Love Juice: A Midsummer Night's Dream And The Phaedra-Hippolytus Myth, Katherine Shakespeare

Undergraduate Honors Capstone Projects

One of the oldest recurring western mythical traditions finds its roots in the Ancient Near East. At the core of this abiding tale is a high-ranking woman, often married, who attempts to seduce a young man, who spurns her. The affronted woman then accuses the youth of assault and either he or both meet a violent end. Often at the heart of each tale lies something monstrous about the potential union of the two individuals.

In the Greek and Roman tradition, one example of this "spurned-woman" motif manifests itself in the Phaedra-Hippolytus myth. No fewer than three ancient playwrights-Sophocles, Euripides, …

A Nationwide Comparison Of Aviation Programs, D. Jason Mcconnell

Undergraduate Honors Capstone Projects

Students considering a college education have many different priorities in mind. When considering a career in aviation after graduation, it brings a whole new set of priorities into the picture. When I was searching for a university degree in aviation I had two major concerns: location and quality of the flight school. Cost was also on my list of concerns but more as a restriction than an option. In other words, I was willing to pay more for the schooling provided it did not get so excessive that I could no longer afford to go. Utah State was among three …

Design Response To Humanitarian Crisis: An Analysis Of Low-Income Labor Camps In Doha, Qatar In The Context Of A Student Charrette, Holly Murdock

Undergraduate Honors Capstone Projects

"Imagine a future where design can alter the quality of life." So began the instructions for "Charrette: A 48 hour Design Challenge" hosted by Virginia Commonwealth University's School of the Arts in Qatar. ("Charrette," 2007.) Combining sustainable design solutions with issues of human rights, an experiment in design education was created to challenge students to improve the quality of life for some of the world's most disadvantaged workers.

Investigating The Role Of Transcription Factor Ap-2�� In Reproduction, Anne Rachelle Howlett

Undergraduate Honors Capstone Projects

The proper formation of gametes is critical for the propagation of species and for the fertility of the individual. The molecular pathways involved in gamete formation remains elusive, therefore, identification of genes involved is an important prerequisite to further our understanding of reproduction. This research will improve infertility treatments and prevention methods in animals and humans. We created mutants that lacked AP-2�� transcription factor after the mouse had entered meiosis and initiated folliculogenesis. The AP-2�� mutants were still fertile and phenotypically similar to normal mice that expressed AP-2�� transcription factor. We also produced mutants that lacked AP-2�� transcription factor during …

A Formal Approach To Specifying And Verifying Spacecraft Behavior, Allan I.S. Mcinnes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Process algebra can provide spacecraft designers with a mathematical formalism for specifying, understanding, analyzing, and verifying spacecraft system behavior. Although it is standard practice to mathematically model and analyze the subsystems of a spacecraft to ensure that they will function correctly when built, the system-level behavior of the spacecraft is generally understood in much less rigorous terms. This leaves the spacecraft system vulnerable to design errors which may not become apparent until the integration and test phase, when design changes are most expensive. In this dissertation, we develop a formal approach to engineering spacecraft behavior, based on mathematical models of …

Effects Of A Synthetic Cannabinoid On The Reinforcing Efficacy Of Ethanol In Rats, Ericka M. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The co-abuse of alcohol and marijuana is widespread, although the mechanisms underlying this behavior are unclear. There is some evidence of a relationship between the neural processes that mediate the effects of ethanol and marijuana. For example, research has shown that exposure to marijuana increases responding for, and intake of, ethanol. The alcohol deprivation effect is an anima l model of alcoholism that suggests that the reinforcing efficacy of ethanol, as measured by intake, increases following a period of deprivation. Recent research indicates that rats chronically exposed to marijuana during periods of alcohol deprivation consume ethanol above and beyond deprivation …

Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen's epiphytic lichen …

Bats And Mines: Evaluating Townsend's Big-Eared Bat Maternity Colony Response To Reclamation, Gabrielle F. Diamond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the loss or modification of natural roosting habitat afforded by caves, abandoned mines have assumed increased importance as surrogate roosting sites for Townsend's big-eared bats (Corynorhinus townsendii) and other chiropteran species. However, increasing concerns for human safety have led to accelerated programs for mine closure. In efforts to protect roosting sites in mines showing significant bat activity, "bat compatible" gates are installed, thus allowing continued access to mine workings. Aside from ensuring public safety, these structures afford protection from disturbance to roosting bats. To date few posting-gating studies have been conducted to obtain information on the effects …

The new approach involves a thorough inventory of the historic character, in depth research of the historic elements that contribute to the historic character, development of design …

Breeding Behavior And Space Use Of Male And Female Mule Deer: An Examination Of Potential Risk Differences For Chronic Wasting Disease Infection, Leslie R. Mcfarlane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dynamics of pathogen and host relationships relative to disease transmission in wildlife populations are important ecological processes to understand, particularly since spatial dynamics of disease can be driven by movement, behavior, and dispersal of animals. Chronic Wasting Disease (CWD) is an example of this important interface, where little is known regarding origin of the disease or routes of transmission. Surveillance data for CWD in free-ranging mule deer indicates that breeding-age male deer have 2-4 times higher prevalence rates than females or younger age males. In an effort to understand differences that might increase risk for exposure to CWD infective …

The Marriage Of Eolian Rock Properties And Deformation Of The Nugget Formation; Anschutz Ranch East Field: Northeast Utah And Southwest Wyoming, Dustin J. Keele

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Nugget Formation in the Anschutz Ranch East field, northeast Utah and southwest Wyoming, provides an exceptional example of how primary eolian rock properties have a considerable influence on the style of structural deformation. Both new and existing subsurface data were integrated for an overall characterization of sedimentologic and diagenetic heterogeneities, which demonstrate relationships with different styles of structural compartmentalization in reservoirs. The Anschutz Ranch East field is a large asymmetric anticlinal trap in the Utah-Wyoming thrust belt. Three cores were analyzed in order to investigate brittle deformation in eolian facies: dune, apron, and interdune. Selected cores are located along …

Psychosocial Variables And Their Relationship To Diabetic Outcome Among The Strong Heart Study Cohort, Brian D. O'Leary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diabetes mellitus is one of the leading causes of death and disability in the United Sates. Certain Native American groups have been harder hit than the mainstream population, both in prevalence of the disease and in rates of related complications. The highest known prevalence in the world is found among a Southwestern U.S. Tribe, and other Native American Tribes have demonstrated similar prevalence rates. It has been shown that certain psychological factors such as depression and hostility impact both the occurrence and outcome of certain diseases, including diabetes.

This study examined whether those individuals who have not met the criteria …

The Temporal Relationship Between Environmental Factors And Psychological Symptoms In Native American Adolescents, Georgia Lee Matt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native American youth often experience high rates of environmental risk factors that may put them at increased risk for developing psychological problems, yet research within this high-risk population is severely limited.

The present study was designed to provide information on the rate of psychological symptoms in a sample of Native American youth, and evaluate the impact of environmental factors (risk, protective, and cultural) on psychological disorder symptoms over time. Data were collected with a sample of Native American youth using the Youth Self Report, the Substance Abuse Subtle Screening Inventory–Adolescent 2, and a researcher-designed Biodemographic Questionnaire.
