These four questions …

Measuring Multicultural Competence In Counseling, Martha Mae Golubski

Dissertations

Pedersen (1999) described multicultural counseling as the “fourth force” in psychology. The description is used to imply that multiculturalism is the next theory to understand human behavior, complementary to the other three forces: psychodynamic, behavioral, and humanistic explanations. Despite the attention being given to multiculturalism, professional organizations, training institutions, and service providers are still trying to understand what it means to have competency in multicultural counseling. Researchers have made decades of efforts to define and measure multicultural counseling competence; yet, there is still limited data about how multicultural training efforts influence these competencies and how counselor multicultural competency affects clients’ …

One of the most pressing factors for new teachers is deciding what to actually teach each day. For educators, the curriculum represents the master plan that both guides their educational efforts and supplies the tools to get the job done. However, new teachers experience varying levels of curriculum support when they begin their careers, and some receive absolutely no support at all. This study describes those cases of beginning a teaching career with little to …

The Effects Of Adolescent Trauma, Mental Health Treatment, And Demographic Variables On Educational Outcome, Christopher Postema

Dissertations

Poor educational performance in adolescence can occur due to trauma, substance use, or other stressors. This study used conflict theory as a foundation, suggesting differences in educational outcomes can be attributed to systems perpetuating the current power structures that cause inequality in academic opportunities and performance. Trauma in adolescence can have adverse effects on educational outcomes and emotional stability. Research suggests that mental health therapy as well as a reduction in trauma symptoms can improve educational outcomes. Race, gender, substance use, socioeconomic status, and employment are important variables that could influence educational outcomes. Interaction terms were found in the literature …

Exploring The Dimensions Of Lesbian, Gay, And Bisexual Affirmative Clinical Supervision, Lindsey N. Dollar

Dissertations

Graduate programs have continued to improve over time regarding incorporating training on LGB issues into coursework and practicum experiences with less emphasis on supervision. Since supervision is a major training area where therapists learn about clients and themselves, it becomes an important area for also teaching supervisees how to work with minority populations. However, relatively absent from discussions of cultural influences in supervision is a focus on LGB concerns, and missing is the ‘how to’ within the supervisory relationship. This quantitative investigation sought to learn how clinical supervisors with knowledge of LGB issues and people implement LGB-affirmative supervision, and to …

School Accountability Within The Dominican Republic: A Qualitative Study Of School Principals’ Beliefs And Knowledge, Massiel Cohen Camacho

Dissertations

The school accountability system in the Dominican Republic (DR) involves the use of several national assessments, the reporting of such data, and the training of principals on how to use such data as part of school improvement efforts. While this type of indicator accountability system does not include specific consequences, there is still significant measuring and reporting of student achievement data, with the implied connotation of teacher and principal responsibility for specific school outcomes. The problem addressed in this study was the lack of research on what school principals know about such school accountability in the DR, and how they …

Promoting Equal Interactions In Early Childhood Settings, Daphne Snyder

Dissertations

In the United States, Black, Indigenous, and People of Color (BIPOC) students are more likely to face disciplinary action (e.g., exclusion, suspension, and expulsion from the classroom) for engaging in the same challenging behaviors as their white peers (Badger et al., 2018; Little & Tolbert, 2018; Noguera, 2003). Due to the discrepancy in disciplinary practices, students are at risk of continued negative interactions with their teachers (Decker et al., 2007; Wymer et al., 2020). One way to improve teacher interactions toward BIPOC students is through equity-focused performance feedback regarding praise and reprimand rates (Knochel et al., 2022). The purpose of …

Towards Reliable Hepatocytic Anatomy Segmentation In Laparoscopic Cholecystectomy Using U-Net With Auto-Encoder, Koloud Najem Alkhamaiseh

Dissertations

Despite the advantages of minimally invasive surgeries that depend heavily on vision, the indirect access and lack of the 3D field of view of the area of interest introduce some complications in the desired procedures. Fortunately, the recorded videos from these procedures offer the opportunity for intra-operative and post-operative analyses, to improve future performance and safety.

Deep learning models for surgical video analysis could therefore support visual tasks such as identifying the critical view of safety (CVS) in laparoscopic cholecystectomy (LC), potentially contributing to the reduction of the current rates of bile duct injuries in LC. Most bile duct injuries …

Simulating Strongly Coupled Many-Body Systems With Quantum Algorithms, Manqoba Qedindaba Hlatshwayo

Dissertations

The complexity of the nuclear many-body problem is a severe obstacle to finding a general and accurate numerical approach needed to simulate medium-mass and heavy nuclei. Even with the advent of exascale classical computing, the impediment of exponential growth of the Hilbert space renders the problem intractable for most classical calculations. In the last few years, quantum algorithms have become an attractive alternative for practitioners because quantum computers are more efficient in simulating quantum physics than classical computers. While a fully fault-tolerant universal quantum computer will not be realized soon, this dissertation explores quantum algorithms for simulating nuclear physics suitable …

Evaluation Of A Brief Act Intervention For Reducing Depression And Anxiety Symptoms In Sexual And Gender Minority Adults, Allie Mann

Dissertations

Sexual and gender minority individuals (SGM) are at increased risk for psychological disorders compared to the general population. Despite this well-documented disparity in mental health outcomes, there is a stark lack of treatment studies examining SGM mental health. An accumulation of research has demonstrated that the source of this disparity is increased exposure of SGM individuals to stigma-related minority stress. It is necessary to examine psychological pathways that are impacted by stigma and the treatments that can reduce psychological distress in this population. Currently, we do not have the research evidence to answer the questions of if current evidence-based treatments …

Visual Circuitry In Adaptive Behavior: Extraction Of Complex Visual Image Information By Arrays Of Non-Image Forming Eyes, Thomas Kipp Halladay Groves

Dissertations

A complete understanding of how neural circuitry underlies the detection and integration of visual cues continues to elude researchers in the 21st century. Since the dawn of life on earth, light has exerted enormous selective pressure on all living organisms. Visual systems represent one of the most common sensory systems in existence, with significant homologies among elements of these systems, such as photopigments and developmental genes. Offering nearly unmatched single cell access at all levels of its nervous system, the European medicinal leech (Hirudo spp.) is an excellent system in which to identify behaviorally relevant neuronal circuits. Hirudo evolved discrete …

Effects Of A Self-Forgiveness Intervention On Recovery From Substance Use Disorders, Michael Saltzman

Dissertations

Previous research has highlighted the relationship between shame, guilt, and problematic substance use (Gueta, 2013; Luoma et al., 2019; McGaffin et al., 2013; Rahim & Patton, 2015). Self-forgiveness has been associated with positive outcomes for individuals in recovery with substance use disorders (SUDs), though only one prior study has explored the effects of a selfforgiveness intervention for individuals in treatment (Scherer et al., 2011). This study examines the effects of a self-forgiveness intervention on state shame and guilt, state self-forgiveness, and drug avoidance self-efficacy, and it is the first intervention study to focus on self-forgiveness for individuals with SUDs receiving …
