A Narrative Case Study Of Transfer Students In Instrumental Music Education, Ashley Glenn

Dissertations

Transfer students in music fields face challenges that are different from other fields of study. Research has shown that transfer students in music are expected to acclimate and operate as upperclassmen with minimal onboarding while also potentially having to retake courses they received credit for at the community college level. This study examines the experiences of five transfer students in music education through the lens of Schlossberg’s transition theory and Dewey’s model of transaction. Building on existing transfer student research, it asks: what do transfer students experience in terms of acceptance and self-integration, and how do these experiences affect transfer …

Predicting Political Development After United States Military Assistance: Evidence From Case Study Analysis, Susan Rae Alaniz

Dissertations

During the administration of former President Barak Obama, United States foreign policy increased its focus on international development instability that threatened U.S. national security. In 2010, President Obama issued Presidential Policy Directive 6, which declared that international development is a vital U.S. national interest. This was a watershed moment for not just how the United States views its national interests, but in which resources should be dedicated to protect them. In 2017, the U.S. Department of Defense has security assistance relationships with 155 countries. These countries represent a wide range of international development challenges.

We propose a generic prioritization and resource management algorithm that can be used to prioritize the processing of received packets in vehicular networks. We formulate …

The Assessment Of Co2 Exposures, Workload Demands, And Musculoskeletal Disorder Risk On Heart Rate For Select Craft Brewery Job Tasks, David L. Huizen

Dissertations

Americans have embraced craft beer, and the ensuing demand has resulted in an ever-increasing number of craft breweries opening over the past 20 years. Craft brewers are generally small employers and, as such, lack the resources necessary to address the safety and health of their employees adequately. Brewers face many safety and health hazards in their work environment. These hazards include exposures to carbon dioxide (CO₂), workload demand, and MSD risk. It is essential to evaluate these hazards in craft breweries as they handle carbon dioxide (CO₂) differently than large breweries by having the CO_{2 …}

Establishing Auditory Discrimination And Echoic Stimulus Control With An Auditory Matching Procedure, Clare Christe

Dissertations

A generalized auditory matching repertoire is considered an early milestone in the development of verbal behavior (Greer & Keohane, 2006). Previous literature has demonstrated that the auditory matching (AM) protocol can improve echoics in individuals with developmental delays (Brown, 2005; Choi, Greer & Keohane, 2015; Du, Speckman, Medina, & Cole-Hatchard, 2017). However, some children experience difficulties with the match-to-sample (MTS) format of the AM protocol, if they are unable to perform delayed MTS tasks.

One alternative to MTS is the go/no-go procedure (Serna, Dube, & McIlvane, 1997), which requires the student to make a simple discrimination (i.e., same/different) between two …

A Framework For Using Fused Image Data In Statistical Process Control, Shengfeng Chen

Dissertations

The use of image data in manufacturing quality control systems has grown rapidly over the years. Technological advancements in imaging devices (e.g., digital cameras, x-ray scanners, infrared cameras) have provided convenient and cost-effective ways to obtain images. These images contain important quality features (e.g., textures and product dimensions) that can be used to monitor, diagnose, predict, and control manufacturing processes. A key tool for monitoring images is statistical process control charts. Integrating images of parts to detect process shifts can significantly improve a quality systems efficiency. Unfortunately, appropriate techniques that take full advantage of data-rich images for control charting are …

An Evaluation Of Different Measures Of Social Problem-Solving: Using Ecological Momentary Assessment, Dana B. Goetz

Dissertations

The present study recruited a sample of undergraduate college students and examined the extent to which three measures of social problem-solving measured the construct of social problem-solving. A self-report measure (i.e., Social Problem-Solving Inventory-Revised Long), analogue task (i.e., the Means-Ends Problem-Solving task), and ecological momentary assessment (i.e., a diary card on real-life events) were compared. It was hypothesized that the three measures would assess different aspects of social problem-solving. The analogue task would theoretically be a measure of ability to generate solutions to a problem, the diary card would theoretically measure implementation of solutions in real-life, and the self-report measure …

Romantic Relational Aggression Among College Students: A Moderated Mediation Study Of Attachment Style, Romantic Jealousy, Mate Value, And Relationship Investment, Skylar Hicks

Dissertations

Most of the research on intimate partner violence has concentrated on overt physical and verbal aggression, and less is known about relational aggression in the framework of romantic relationships. Relational aggression is more prevalent in college students’ romantic relationships compared to physical aggression and may be a risk factor for intimate partner violence. Additionally, a number of adverse correlates have been associated with romantic relational aggression, suggesting that it is worthy of study independent of its association with intimate partner violence. The present study explored the relationships among adult attachment, romantic jealousy, mate value, relationship investment, and romantic relational aggression …

Multicultural Competence, White Privilege Attitudes And The Working Alliance In Clinical Supervision, Michelle A. Stahl

Dissertations

Research indicates that White supervisors have difficulty facilitating and integrating multicultural issues in supervision (Fong & Lease, 1997; Hird, Tao, & Gloria, 2004). A factor that interferes with a multicultural focus in supervision is the multicultural competence of the supervisor (Miville, Rosa, & Constantine, 2005). Moreover, as a result of White privilege, White supervisors may also be less aware of their cultural selves and subsequently less inclined to discuss multicultural issues in supervision (Hird et al., 2004). Lack of attention to important multicultural issues, such as White privilege, can interfere with the development of an effective supervisory alliance (Constantine & …

Between Two Worlds: A Phenomenological Exploration Of Experiences And Understandings Related To Race For Black Transracially Adopted Emerging Adults, Kyrai Antares

Dissertations

The current study provides a rich description of experiences and understandings related to race for transracially adopted Black emerging adults who were raised in Michigan or Ohio by White parents. Current adoption policy requires that race not be considered as a factor in foster and adoptive placements, and there is no required multicultural, race-focused training for White adoptive parents of children of color. This study begins a new line of research looking closely at the stories of transracial adoptees of a specific age group, racial identity, and geographical location of upbringing. The intention is to gain a better understanding of …

Dissertations

Buer, Karin. Variations on a Theme of Robert Schumann: Intertextual References and Private Meaning in Clara Schumann’s Opus 20 and Johannes Brahms’s Opus 9. Published Doctor of Arts dissertation, University of Northern Colorado, 2020. For centuries, composers have used their music as an expressive tool, imbuing it with publicly accessible meaning that often reflects the time and place in which the composer lived. Throughout the nineteenth century, the view of music as a means of expression, specifically self-expression, became crystallized as never before. Robert Schumann and other literary-minded nineteenth-century composers thus communicated, through their art, meanings which were both public …

Ally Or Enemy: The Impact Of Leadership On United States Army Combat Veterans’ Deployment Experiences Who Have Served In Iraq And Afghanistan, Derik Van Baale

Dissertations

Soldiers’ deployment experiences have been well-researched and studied, but the primary focus has been on enemy-induced trauma. Being a combat veteran who served in Iraq myself, and as someone who has counseled a plethora of combat veterans, I am keenly aware that there is more than exposure to enemy fire and the loss of comrades that can leave a lasting impression. Often, the actions by and interactions with leaders during deployments can also prove to be quite impactful to soldiers. However, very little research exists on the impact of leadership behavior as a factor during a soldier’s deployment experience and …

The Effects Of A Course Oriented In Critical Race Theory On White Counselor Trainees’ Multicultural Counseling Competence, White Privilege Attitudes, And Cross Racial Contact, Dawnielle D. Simmons

Dissertations

The current study examined the effects of a single and required Critical Race Theory (CRT)-oriented multicultural course on White, master-level counselor trainees with and without clinical experience. More specifically, the study examined differences in White counselor trainees’ responses to instruments that assessed White privilege attitudes, multicultural counseling competence, and cross-racial contact comparing trainees that had taken the required multicultural course with those who had not. Previous research suggests that when a single multicultural counseling course is a requirement of counselor training, multicultural counseling competence and White privilege awareness tend to increase. In the current study, a CRT-oriented course was used …
