The Political Business Cycle: Endogenous Election Timing & Hyperbolic Memory Discounting, Jake R. Cottle Aug 2019

The Political Business Cycle: Endogenous Election Timing & Hyperbolic Memory Discounting, Jake R. Cottle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the models analyzed in this paper, there exists an incumbent politician with one objective, two choices, and voters who remember the past differently. The politician's primary goal is to get reelected, which is done by maximizing the number of votes on the day of election. The politician can increase their chances of reelection if they influence the state of the economy over time and ensure the economy is in its 'best' state on the days leading up to the election.

In conducting this research, I wanted to study how different rates of memory decay influences the choices the politician …


The Effects Of Behavior Skills Training And Self-Monitoring On Paraprofessionals’ Use Of Incidental Teaching Procedures In A Preschool Classroom, Bayley Thompson Aug 2019

The Effects Of Behavior Skills Training And Self-Monitoring On Paraprofessionals’ Use Of Incidental Teaching Procedures In A Preschool Classroom, Bayley Thompson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This project investigated effects of behavior skills training (BST) and self-monitoring on paraprofessionals’ use of incidental teaching procedures in a preschool classroom. Target behaviors involved correctly implementing two incidental teaching procedures: inadequate portions and sabotage. During baseline the paraprofessional displayed low levels of correct implementation of incidental teaching procedures. The participant then completed a training which included BST and self-monitoring. In addition to treatment data collection, the paraprofessional completed an incidental teaching questionnaire and a social validity survey as secondary measures. Results showed that the BST and self-monitoring package improved the participants’ implementation of correct incidental teaching procedures.

A Survey Of College Students With Learning Disabilities And Attention Deficit Hyperactivity Disorder To Identify Their Relationship And Use Of College Disability Resource Centers, Telia M. West

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

College students with learning disabilities (LD) and/or attention deficit hyperactivity disorder (ADHD) complete college at lower rates than their non-disabled peers (Newman & Madaus, 2015). Colleges receiving federal funding are required to have a disability resource center (DRC) that provides and coordinates accommodations for students with disabilities. This project examined the factors that led students with LD and/or ADHD to initially contact their college DRC. This project examined data from 61 college students pursuing an undergraduate degree with LD and/or ADHD who had already contacted their DRC. A survey was sent to those students asking about circumstances surrounding their …


Fragmentary Memories: The Cultural Significance Of Famine Echoes In Dracula, Moira Hegarty Aug 2019

Fragmentary Memories: The Cultural Significance Of Famine Echoes In Dracula, Moira Hegarty

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This Plan B thesis explores the questions: What echoes of the 1845 Potato famine exist in Dracula and how do those echoes impact our understanding of the famine’s cultural impact? Dracula has been studied extensively both as an important example of gothic Victorian literature and as a chance to reclaim a native Irish author from the British. By looking at Dracula through the lens of Ireland’s 1845 Potato famine some of the structural and narrative oddities resolve themselves, such as Stoker’s decision to introduce so many opposing images and ideas to create a sense of uncertainty and rob the reader …

First, the study found that the courses that posted more open-ended prompts, evaluated students’ discussion messages posted …


Evaluating The Effectiveness Of Livestock Guardian Dogs: Loss-Prevention, Behavior, Space-Use, And Human Dimensions, Daniel Kinka Aug 2019

Evaluating The Effectiveness Of Livestock Guardian Dogs: Loss-Prevention, Behavior, Space-Use, And Human Dimensions, Daniel Kinka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock guardian dogs – or “LGDs” – are commonly used by domestic sheep ranchers and reduce the need for killing wild carnivores to protect livestock. LGDs are mostly used in the United States to reduce the number of livestock killed by coyotes, but whether they can prevent killing by larger carnivores like wolves and grizzly bears is unclear. It is important to identify which behavioral traits and LGD breeds work best for guarding livestock so that ranchers can protect their stock and environmentalists can enjoy a greater number of wild animals on the landscape. This study investigated the effectiveness of …


Examining The Effects Of Familism On The Association Between Parent-Adolescent Conflict, Emotion Regulation, And Internalizing Problems Among Latinx Adolescents, Kenia Carrera Aug 2019

Examining The Effects Of Familism On The Association Between Parent-Adolescent Conflict, Emotion Regulation, And Internalizing Problems Among Latinx Adolescents, Kenia Carrera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Latinx adolescents report higher levels of anxiety and depression symptoms (i.e., internalizing symptoms) compared to other ethnic groups. Research studies primarily conducted with European American youth have concluded that difficulties in emotion regulation and parent-adolescent conflict are associated with an increased risk for youth internalizing symptoms. Additionally, an important Latinx cultural value, familism, has been identified as a protective factor for internalizing symptoms for Latinx adolescents. Therefore, the current study examined how familism, parent-adolescent conflict, and difficulties in emotion regulation interact to influence the development of internalizing symptoms among Latinx adolescents. It was hypothesized that (a) parent-adolescent conflict and difficulties …


Adapting Environmental Ethics And Behaviors: Toward A Posthuman Rhetoric Of Community Engagement, Beth J. Shirley Aug 2019

Adapting Environmental Ethics And Behaviors: Toward A Posthuman Rhetoric Of Community Engagement, Beth J. Shirley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

What persuades people one way or another to accept or deny climate change? More importantly, what persuades people to act on, ignore, or even be defiant of climate change? We would like to think that people are motivated when they hear the science explained clearly and when they are presented with a clear understanding of how their actions have a lasting impact. Yet the science on climate change has been made clear for some time, and doubt in climate change science is rampant (at least in the United States).

This dissertation seeks to answer these questions and develop a new …

Teachers' Conceptions Of Mathematics And Intelligent Tutoring System Use, Andrew R. Glaze

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this mixed-methods study was to investigate the relationship between teachers’ conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A conception is a mixture of beliefs and knowledge. The participants in this study were 93 junior high school mathematics teachers from three school districts in the Midwest. Data were gathered using a two-part online survey. The first part of the survey contained questions about their use of intelligent tutoring systems, graphing calculators, Desmos and dynamic …


A Structural Equation Modeling Approach Combining Multitrait-Multimethod Designs With Moderated Mediation Analysis, Kaylee Litson Aug 2019

A Structural Equation Modeling Approach Combining Multitrait-Multimethod Designs With Moderated Mediation Analysis, Kaylee Litson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Researchers who study clinical and developmental psychology are often interested in answering questions such as how interventions work, when treatment begins to improve health outcomes, or for whom treatment has the greatest impact. Answers to these and similar questions impact the general understanding of health and behavior, and can be imperative for effectively implementing intervention and prevention programs. To evaluate such complex relationships among variables, researchers have turned to moderated mediation analysis. Moderated mediation analysis is a statistical tool used to identify the conditional processes among observed or latent variables. However, in developmental and clinical psychology, variables are regularly measured …


Urban Alaskan Moose: An Analysis Of Factors Associated With Moose-Vehicle Collisions, Lucian R. Mcdonald Aug 2019

Urban Alaskan Moose: An Analysis Of Factors Associated With Moose-Vehicle Collisions, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As human populations continue to grow and encroach into wildlife habitats, instances of human-wildlife conflict are on the rise. Increasing numbers of reported wildlife-vehicle collisions (WVCs) provide tangible evidence of anthropogenic impacts on wildlife as well as increasing threats to human health and safety. Increasing WVCs are of particular concern, especially those involving large-bodied ungulates such as moose (Alces spp.), because of the increased risk of property damage, personal injuries, and human fatalities. Motorists directly involved in a WVC are at risk of injury or mortality, but other motorists are also put at risk due to road obstructions and traffic …


Physiological, Behavioral, And Self-Report Outcomes Of Acceptance And Regulation Approaches To Exposures For Intrusive Thoughts, Brooke M. Smith Aug 2019

Physiological, Behavioral, And Self-Report Outcomes Of Acceptance And Regulation Approaches To Exposures For Intrusive Thoughts, Brooke M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cognitive-behavioral therapy that includes exposure, or intentionally and systematically confronting feared situations, is the gold standard psychological treatment for obsessive-compulsive disorder. However, less than half of those who begin this treatment are considered to have recovered from their disorder at the end of treatment, and this number is even smaller in the months following the end of treatment. Leading theories regarding how treatment changes occur focus on reducing fear, and they do not include “voluntary” (i.e., operant) behaviors, such as avoidance, that are key features of the disorder. Acceptance-based approaches to exposure do not focus on fear reduction, but directly …


Developmental Trajectories Of Aggression From Toddlerhood To Early Adolescence In Boys And Girls: Exploring Early Predictors And Later Outcomes, Sujung Park Aug 2019

Developmental Trajectories Of Aggression From Toddlerhood To Early Adolescence In Boys And Girls: Exploring Early Predictors And Later Outcomes, Sujung Park

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early behavior problems, such as childhood aggression, emerge in the second year of life and decrease prior to school entry for typically developing children. However, some children show frequent and persistent aggression and may be at risk for subsequent difficulties that lead to poor school and life outcomes. The current study aimed to identify aggression patterns in children from toddlerhood to early adolescence for boys and girls together and separately. This study also explored early influences on aggressive behaviors at age two, such as mothers’ parenting behaviors, cumulative family risk, and early child characteristics. A range of difficulties in early …


Dementia Caregiver Coping Strategies And Caregiver-Care Recipient Relationship Closeness: Associations With Care-Recipient Outcomes, Stephanie Behrensberg Aug 2019

Dementia Caregiver Coping Strategies And Caregiver-Care Recipient Relationship Closeness: Associations With Care-Recipient Outcomes, Stephanie Behrensberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project used data from the Dementia Progression Study, a longitudinal, population-based study based out of Cache County, Utah. Statistical models were used to examine the association between caregiver factors, the care environment, and cognitive outcomes in persons with dementia. Mediational analyses were also used to examine if the care environment, inferred for nutritional status, engagement in physical and cognitively stimulating activities, mediated the relationship between the closeness/caregiver coping strategies and cognition in persons with dementia. Results showed that closer caregiver-care recipient relationships were associated with better nutritional status and more engagement in number of cognitively stimulating activities as well …


Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray Aug 2019

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to develop a standardized agricultural literacy assessment using the National Agricultural Literacy Outcomes (NALOs) as benchmarks. The need for such an assessment was born out of previous research, which found that despite numerous programs dedicated to improving agricultural literacy, many students and adults remain at low or very low levels of literacy. Low literacy levels lead to negative associations with the production and processing of food, clothing, and shelter, as well as misinformed public perceptions and policies. Agricultural literacy researchers recognized that the development of a standardized assessment for post-12th grade, or equivalent, could unify …


An Assessment Of Self-Determination Skills In Transition-Age Students With Disabilities Following Instruction Using The My Transition Portfolio Program, Eliza Jex Aug 2019

An Assessment Of Self-Determination Skills In Transition-Age Students With Disabilities Following Instruction Using The My Transition Portfolio Program, Eliza Jex

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The successful transition for students with disabilities into adult roles and activities post high-school, including employment, participation in postsecondary educational opportunities, and inclusion in social activities, continues to be a challenge for these individuals. Research has established that the development of certain skills earlier on can support students with disabilities in making a successful transition into these adult roles. The development of self-determination skills is one such practice. There is a need in the field of education to further research in programs that are available for teachers in providing instruction in self-determination skills. This study sought to establish research on …

Service members and veterans of the current era, Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) are at a high risk for a variety of psychological disorders and physical health impairments. Common disorders among male service members and veterans include posttraumatic stress disorder (PTSD), substance use, and hypersexuality. Each of these disorders affect all aspects of an individual’s life and can deteriorate important interpersonal relationships or impair functioning in a variety of contexts. All these variables can affect sexual health and functioning in these service members. Sexual functioning is an important aspect of overall well-being, …


Agent-Based Model To Manage Household Water Use Through Social-Environmental Strategies Of Encouragement And Peer Pressure, Ryan James Aug 2019

Agent-Based Model To Manage Household Water Use Through Social-Environmental Strategies Of Encouragement And Peer Pressure, Ryan James

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inelastic price responses, demand hardening, and poor public awareness reduce the effectiveness of demand side strategies on water savings. This project quantified phycological household’s factors of attitudes, peer support, opportunities on water conservation with two social-environmental management strategies of encouragement and peer pressure. An agent-based model was populated with data for Logan, Utah using surveys, municipal billing, aerial imagery, weather monitoring stations, and flow, frequency, and durations of appliance use data. Results indicated those households with higher attitudes, peer support and opportunities saved the most water while peer pressure saved more than encouragement when using small and diverse social networks …


A Narrative Approach To Educational Video Training, Matthew S. Havertz Aug 2019

A Narrative Approach To Educational Video Training, Matthew S. Havertz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers often use videos to teach their students, but stories are not used as often in educational videos as they could be. Experts tell us that stories are an important part of teaching and learning. Unfortunately, there is only a small amount of research and no definitive expert agreement about stories used in educational videos. This is especially true for videos used with technical education students, like mechanic students or dental assisting students. In this study, dental assisting students learned how to assist a dentist with a standard cavity procedure after watching a video with or without a story. The …


Depression Mediates The Association Of Disordered Eating Behaviors And Sexual Function In Female Service Members And Veterans, Whitney S. Livingston Aug 2019

Depression Mediates The Association Of Disordered Eating Behaviors And Sexual Function In Female Service Members And Veterans, Whitney S. Livingston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Poor sexual function is comprised of diminished sexual desire and arousal, presence of sexual pain, inability to reach orgasm, and low satisfaction. Worse sexual function is associated with disordered eating behavior; however, the mechanism through which this association exists remains unclear. Theory of sexual function suggests that depression mediates the association of disordered eating behaviors and poor sexual function in female service members and veterans, but this has yet to be tested empirically. The purpose of the current study was to examine whether depression mediated the association of disordered eating behaviors and sexual dysfunction.

Participants (N=511) were partnered …

Teachers’ Stories About Teaching: Collaborative Dialogues As Open Educational Resources, Ekaterina Arshavskaya Jul 2019

Teachers’ Stories About Teaching: Collaborative Dialogues As Open Educational Resources, Ekaterina Arshavskaya

Journal on Empowering Teaching Excellence

This paper examines the nature of teacher learning through a social-constructivist perspective and describes instructional strategies utilized with teachers during an international teaching assistants’ (ITAs’) training workshop offered at the Utah State University (USU). The strategy used involved eliciting and structuring exemplary teachers’ stories about teaching to serve as a basis for class discussions and other assignments. These teachers’ stories, recorded on video, were then shared online through the university website and YouTube. In this way, new teachers gained access to co-constructed and pedagogically appropriate teacher knowledge represented by authentic teachers’ voices.

Psychology Faculty Publications

Background Despite the large number of evidence-based practices (EBPs) ready for implementation, they are the exception in usual care, especially for ethnic minority patients, who may not have access to trained health professionals. Providing EBP training as part of a graduate curriculum could help build the pipeline of professionals to provide quality care. Methods We conducted a before-after study to determine whether we could implement a blended learning strategy (BL; i.e., in vivo and online training) to teach an EBP in university settings. Feasibility in this pilot was operationalized as knowledge acquisition, satisfaction, fidelity, acceptability, and usability. Using GenerationPMTO as …


How Vision Governs The Collective Behaviour Of Dense Cycling Pelotons, J. Belden, Mohammad M. Mansoor, A. Hellum, S. R. Rahman, A. Meyer, C. Pease, J. Pacheco, S. Koziol, Tadd T. Truscott Jul 2019

How Vision Governs The Collective Behaviour Of Dense Cycling Pelotons, J. Belden, Mohammad M. Mansoor, A. Hellum, S. R. Rahman, A. Meyer, C. Pease, J. Pacheco, S. Koziol, Tadd T. Truscott

Mechanical and Aerospace Engineering Faculty Publications

In densely packed groups demonstrating collective behaviour, such as bird flocks, fish schools or packs of bicycle racers (cycling pelotons), information propagates over a network, with individuals sensing and reacting to stimuli over relatively short space and time scales. What remains elusive is a robust, mechanistic understanding of how sensory system properties affect interactions, information propagation and emergent behaviour. Here, we show through direct observation how the spatio-temporal limits of the human visual sensory system govern local interactions and set the network structure in large, dense collections of cyclists. We found that cyclists align in patterns within a ± 30° …


“You Shouldn’T Worry Walking A Block And A Half To Your Car”: Perceptions Of Crime And Community Norms In The Bakken Oil Play, Jessica Ulrich-Schad, Michael Fedder, Julie Yingling Jul 2019

“You Shouldn’T Worry Walking A Block And A Half To Your Car”: Perceptions Of Crime And Community Norms In The Bakken Oil Play, Jessica Ulrich-Schad, Michael Fedder, Julie Yingling

Sociology, Social Work and Anthropology Faculty Publications

The Bakken oil play experienced substantial population growth from oil and gas development over the last decade, resulting in disruption to social norms at the community level. We surveyed residents in a county in Montana and a county in North Dakota about their perceptions of crime resulting from the most recent boom, finding that residents perceived high levels of various types of crimes resulting from the boom and that many also changed their daily behavior out of fear of such crime. In addition, we asked about current perceptions of community norms and find evidence that perceived levels of helping and …


Boundaries Of The Construct Of Unemployment In The Pre-Retirement Years: Exploring An Expanded Measurement Of Lost-Work Opportunity, Maren Wright Voss, Soham Al Snih, Wei Li, Man Hung, Lorie Gage Richards Jun 2019

Boundaries Of The Construct Of Unemployment In The Pre-Retirement Years: Exploring An Expanded Measurement Of Lost-Work Opportunity, Maren Wright Voss, Soham Al Snih, Wei Li, Man Hung, Lorie Gage Richards

Extension Research

There is uncertainty related to whether retirement negatively affects health—possibly due to complexity around retirement decisions. Lost-work opportunity through unemployment or forced retirement has been shown to negatively affect health. Lost-work opportunity can be captured in two measurement fields, either a reported experience of being forced into retirement or reported unemployment. However, 17% of individuals retiring due to the loss of work opportunity identified in qualitative interviewing (i.e., unemployment, temporary lay-offs, company buy-outs, forced relocations, etc.) do not report this unemployment or involuntary retirement in quantitative survey responses. We propose broadening the conceptualization of late-career unemployment to incorporate other lost …
