A Qualitative Study Exploring The Management & Implications Of Power Differentials Experienced By Pre-Licensed Supervisees In Clinical Supervision Settings, Joyti Jariwala

Dissertations

The focus in this qualitative study was to explore how power differentials in supervision create positive and negative experiences between licensed psychologists and pre-licensed doctoral students. The study results provide insight into how supervisees navigate these dynamics during supervision, which typically involves experiential learning environments in which trainees discuss progress, receive feedback, and enhance their skills. The theoretical framework grounding the study was social learning theory, which is based on the idea that individuals learn from modeling, observation, and imitation in a social context (Bandura, 1986). Reflexive thematic analysis was used to recognize similarities in findings gathered via two sets …

Associations Between Combat Exposure, Moral Injury, And Suicidality Among U.S. Military Members: The Moderating Impact Of Positive Rumination, Jeffrey M. Gabelmann

Psychology Theses & Dissertations

Numerous studies have documented the risk for suicide among recent-era veterans with combat experience. Recently, moral injury has emerged as a possible contributor to suicidality in veterans. To that end, no study has approached the combat exposure-moral injury-suicidality link with a focus grounded in positive psychology. Specifically, the present study explored whether positive rumination, or the reflection on positive emotions and moods, may buffer the deleterious effects of potentially traumatic experiences in warzones on moral injury and suicidality. This study was a secondary analysis of 250 current or former U.S. military members (M_age = 33.3 years) who had …

The Impact Of Peer Observational Learning On Honesty Following A Transgression, Hannah M. Sliman

Psychology Theses & Dissertations

Parents and teachers concerns about the development and socialization of lying aligns with research suggesting that persistent lying is related with delinquency, aggression, and conduct problems. We were interested in examining the difference between two groups: Honest and Praise (HP), and Control Group (CG) for the extent to which exposure to the experimental condition influenced a child’s decision to be honest and confess after a transgression. The study was designed to examine the extent to which observing peers of similar age receiving praise for being honest can promote honesty amongst children. Further, the study determined if gender influences honest reporting. …

A Review Of Secondary Technology Education Teacher Needs In Virginia, M. Kathleen Ferguson

Educational Leadership & Workforce Development Theses & Dissertations

Technology education teachers can have varied pre-service training experiences, thus their needs for classroom support may vary greatly. Perkins V requires evidence-based research to justify the use of funding for professional development. This researcher sought to support Virginia’s secondary technology education teachers, professional organizations, and the Virginia Department of Education’s Technology Education Specialist by providing research to determine professional development needs. This three-phase qualitative study used a survey, documents review, and focus groups to triangulate data to provide information about the research questions. The research questions focused on teachers’ educational background, technology program goals, and issues specific to secondary technology …

Bracketed Assessments In Behavioral Gerontology: Evaluating Preference With Present And Absent Stimuli, Flavia Eduarda Del Castillo Troche

Theses and Dissertations

The present study evaluated the use of bracketed assessments to assess the activity preference of three individuals with dementia. The study proposed an alternative method to traditional stimulus preference assessments, to bridge the gap in behavior analytical literature within behavioral gerontology. Thus, bracketed assessments were conducted using two presentation methods, verbal plus visual presentation and verbal-only presentation. Results suggested that while participants showed consistency within low preferred activity selection in the bracketed assessment, variability was observed among participants’ preferences for high and moderate preferred activities. Both presentation methods yield similar selection results for one participant, however, the other two participants …

Cultural Selection Of Ethical Self-Control Toward Sustainability, Michael Jonathan Passage

Theses and Dissertations

This study consisted of three experiments to improve our understanding of the conditions that foster cooperation related to sustainability. In Experiment 1, participants completed a demographic questionnaire and an environmental and social discounting task. Results (a) support the utility of the environmental discounting task; (b) suggest responding to the discounting task is dissimilar; and (c) show that responding to hypothetical consequences on the social discounting task correlates to actual responding. Experiment 2 evaluated whether interlocking behavioral contingencies (by microculture members) associated with sustainable and non-sustainable aggregate products (Condition A & B) could be selected by cultural consequences (i.e., 20¢ toward …

An Integrated Space Test Lexicon: A Taxonomy For The Integrated Test And Evaluation Of Space Systems, Stephen K. Tullino, Andrew S. Keys, Robert A. Bettinger, Amy M. Cox, David R. Jacques

Faculty Publications

The proposed Integrated Space Test Lexicon is intended to amalgamate the numerous definitions of integrated (IT or IT&E), development test (DT or DT&E), and operational test (OT or OT&E) into unified, service-wide definitions, aligned with the Space Test Enterprise Vision. Refining such definitions will help distill the core characteristics of these fundamental test types to first identify space system activities composing what is traditionally known as DT and OT, then to provide a means of how these activities fit into the IT paradigm and support space system development. In forging a common understanding of how DT and OT support space …

Causes And Consequences Of Mitotic Chromosome Missegregation In Human Pluripotent Stem Cells, Chenhui Deng

Dartmouth College Ph.D Dissertations

Mitosis is a fundamental process that ensures the equal distribution of replicated chromosomes, which carry an organism's genetic material, into two daughter cells. The fidelity of mitosis is paramount, as errors in chromosome segregation result in aberrant chromosome numbers, including gains or losses, a state termed aneuploidy. Aneuploidy impacts a broad range of human conditions, including being one of the major hurdles in early human development where it is the primary cause of miscarriages and birth defects. Strikingly, more than 70% of human preimplantation embryos are aneuploid with mitotic chromosome segregation errors being the most common source of aneuploidy. However, …

Dna-Delivered Monoclonal Antibodies Targeting The P53 R175h Mutant Epitope Inhibit Tumor Development In Mice, Dafei Chai, Xu Wang, Praveen Neeli, Shan Zhou, Xingfang Yu, Kanaga Sabapathy, Yong Li

Faculty, Staff and Students Publications

The tumor suppressor p53 is the most common mutated gene in cancer, with the R175H as the most frequent p53 missense mutant. However, there are currently no approved targeted therapies or immunotherapies against mutant p53. Here, we characterized and investigated a monoclonal antibody (mAb) that recognizes the mutant p53-R175H for its affinity, specificity, and activity against tumor cells in vitro. We then delivered DNA plasmids expressing the anti-R175H mAb or a bispecific antibody (BsAb) into mice to evaluate their therapeutic effects. Our results showed that the anti-R175H mAb specifically bound to the p53-R175H antigen with a high affinity and …

Optimization Of Kidney Health In Liver Transplant Candidates: Pretransplant Considerations And Modalities, Muhammad Y Jan, Kavish R Patidar, Marwan S Ghabril, Chandrashekhar A Kubal

Faculty, Staff and Students Publications

Patients with decompensated end-stage liver disease (ESLD) are at increased risk for mortality, and only liver transplantation (LT) offers meaningful hope for survival. These patients are at risk for kidney dysfunction through the continuum of care for ESLD including LT. We discuss the role of accurate estimation and measurement of baseline glomerular filtration rate in assessment of kidney dysfunction among those with ESLD. Optimizing kidney function is a vital goal in the management of these patients before LT. In this review, we summarize salient aspects of assessing and optimizing kidney function in this patient population. Precipitating factors and different causes …

Triticale As A Source Of Resistance To Wheat Streak Mosaic Virus And Triticum Mosaic Virus, Marcos Winicius Goncalves De Souza

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) present a great threat to wheat production in the Great Plains area of the United States due to the loss of photosynthetic area causing reductions in crop yields. Effective control of these viruses is limited to a few available strategies including controlling volunteer wheat and using currently identified resistant genes to both the vector and viruses. While effective, these genes show temperature sensitivity and yield drag, and evidence that the vectors and viruses can overcome them has been found. Thus, new methods of genetic resistance are urgently needed. Field observations …

Preferential Crystallization Of (±)-Pinenyllithium·Tmeda, Alexander N. Erickson, Curtis Haltiwanger, Masoumeh Rahim, Charles M. Garner

Chemistry Faculty Research and Publications

(±)-Pinenyllithium·TMEDA or (tetra­methyl­ethylenedi­amine-κ²N,N′)(η³-6,6-di­methyl-2-methylenebi­cyclo­[3.1.1]hept­yl)lithium, [Li(C₁₀H₁₅)(C₆H₁₆N₂)], is readily pre­pared from β-pinene, butyl­lithium and TMEDA, and the racemic material pre­fer­entially crystallizes even from 96:4 (92% ee) mixtures of (−)- and (+)-β-pinene, respectively. The structure is monomeric, with the geminal-dimethyl bridge of the bicyclic structure shielding one face of the allyl system, restricting the lithium to the opposite face and preventing the Li–all­yl–Li aggregation observed with some other allyl­lithium systems. The symmetry of the allyl system, bond lengths, bond angles and out-of-plane deviations …

A Comparison Of Structure, Bonding And Non-Covalent Interactions Of Aryl Halide And Diarylhalonium Halogen-Bond Donors, Nicole Javaly, Theresa M. Mccormick, David R. Stuart

Chemistry Faculty Publications and Presentations

Halogen bonding permeates many areas of chemistry. A wide range of halogen-bond donors including neutral, cationic, monovalent, and hypervalent have been developed and studied. In this work we used density functional theory (DFT), natural bond orbital (NBO) theory, and quantum theory of atoms in molecules (QTAIM) to analyze aryl halogen-bond donors that are neutral, cationic, monovalent and hypervalent and in each series we include the halogens Cl, Br, I, and At. Within this diverse set of halogen-bond donors, we have found trends that relate halogen bond length with the van der Waals radii of the halogen and the non-covalent or …

Utilization Of Probiotics To Compete With Clostridioides Difficile For Nutrient-Niches In A Variety Of In Vitro Contexts, April Elizabeth Johnson

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Clostridium difficile is a major threat to public health and primarily affects at risk groups such as elderly, immunocompromised individuals, and individuals on antibiotics. Many decades of research have been conducted to figure out ways to exclude or reduce C. difficile colonization and toxin production. Two major proposed mechanisms for colonization resistance are production of secondary bile salts and competition for nutrients.

In Chapter 2, we found that antibiotic treatment disrupted bile salt metabolism increasing the levels of the primary bile salt cholate and decreasing the levels of deoxycholate, a secondary bile salt. However, bile salts were not required …

Growth And Simulation Of Dielectric-Metal Nanoheterostructured Thin Films By Ballistic Deposition, Shawn Wimer

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This thesis is divided into two related topics: the structural and chemical characterization of dielectric-metal nanoheterostructured thin films grown by glancing angle deposition (GLAD) and the results of the simulated growth of films and structures by GLAD with discrete-space and continuous-space Monte Carlo ballistic simulation.

Individual structures comprising films grown by GLAD were investigated by S/TEM and SEM imaging, electron diffraction, and chemical characterization and mapping by EDX. Different intermolecular interactions within and between different materials, including Si, Ag, Au, and ZrO₂, are linked to differences in the shapes of individual materials in heterostructures, the shape of heterostructures …

Faculty Research, Scholarly, and Creative Activity

Context. Mid-infrared emission features are important probes of the properties of ionized gas and hot or warm molecular gas, which are difficult to probe at other wavelengths. The Orion Bar photodissociation region (PDR) is a bright, nearby, and frequently studied target containing large amounts of gas under these conditions. Under the “PDRs4All” Early Release Science Program for JWST, a part of the Orion Bar was observed with MIRI integral field unit (IFU) spectroscopy, and these high-sensitivity IR spectroscopic images of very high angular resolution (0.2′′) provide a rich observational inventory of the mid-infrared (MIR) emission lines, while resolving the H …

The Effect Of Adamts13 On Graft-Versus-Host Disease, Dan Li, Min Soon Cho, Ricardo Gonzalez-Delgado, Xiaowen Liang, Jing-Fei Dong, Miguel A Cruz, Qing Ma, Vahid Afshar-Kharghan

Faculty, Staff and Student Publications

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) can potentially cure malignant blood disorders and benign conditions such as haemoglobinopathies and immunologic diseases. However, allo-HSCT is associated with significant complications. The most common and debilitating among them is graft-versus-host disease (GVHD). In GVHD, donor-derived T cells mount an alloimmune response against the recipient. The alloimmune response involves several steps, including recognition of recipient antigens, activation and proliferation of T cells in secondary lymphoid organs, and homing into GVHD-targeted organs. Adhesion molecules on T cells and endothelial cells mediate homing of T cells into lymphoid and non-lymphoid tissues. In this study, we showed …

The Price Of Consent, Zohra Ahmed

Faculty Scholarship

This Article demonstrates how hierarchies in the international economy and in international financial institutions have facilitated the U.S.-led Global War on Terror (GWOT). Using U.S.-Pakistan relations as a case study, it shows how the United States has deployed its powerful position at the International Monetary Fund (IMF) to claim Pakistan's consent for its military activities in the region. In the GWOT's first decade, beginning in 2001, the United States openly sought forcible regime change, as in Afghanistan and Iraq; in its second and (now) third decades, the United States has waged covert counterinsurgency campaigns allegedly against militant groups in Muslim-majority …

Civic Education And Democracy's Flaws, Robert L. Tsai

Faculty Scholarship

Today, liberalism and democracy are beset by competitors that seek to return power to religious traditionalists or partisans masquerading as civic republicans. In such an environment, can civic education do some good, and even help bridge our society’s deepening divides?

Seana Shiffrin has characteristically brought deep learning and penetrating insight to the project of civic education in a modern democracy. Against a “dominant” model of citizenship in which “citizens vote and hand off power to their representatives”— which she believes encourages the people to maintain an unhealthy distance from government— she proposes a richer account of political community in which …

Background: Patients with telomere biology disorders (TBD) develop hepatic disease, including hepatitis, cirrhosis, and hepatopulmonary syndrome. No specific treatment exists for TBD-related liver disease, and the role of liver transplantation (LT) remains controversial. Our study objectives were to describe the clinical characteristics, management, and outcomes in patients with TBD-related liver disease, and their LT outcomes.

Methods: Data from 83 patients with TBD-associated liver disease were obtained from 17 participating centers in the Clinical Care Consortium of Telomere-Associated Ailments and by self-report for our retrospective, multicenter, international cohort study.

Results: Group A ("Advanced") included 40 patients with advanced liver disease. Of …

Gaze In Context: Individual And Group Differences In Real-World Visual Attention, Amanda J. Haskins

Dartmouth College Ph.D Dissertations

When exploring a real-world scene, individuals direct their gaze to selectively attend, leaving a trace of their informational priorities. What drives this information selection, and what causes individuals to prioritize information differently from one another? In this dissertation, I aim to understand the influences that guide visual attention as individuals explore real-world environments and to characterize patterns of visual attention that differ among individuals and among groups with neurodevelopmental conditions. In Chapter 1, I introduce a novel eyetracking paradigm, in which participants can actively explore immersive, naturalistic scene photospheres via headmounted virtual reality. Using this paradigm, I demonstrate that naturalistic …

Endovascular Versus Medical Therapy In Posterior Cerebral Artery Stroke: Role Of Baseline Nihss Score And Occlusion Site, Italo Linfante, Guilherme Dabus

All Publications

Background: Acute ischemic stroke with isolated posterior cerebral artery occlusion (iPCAO) lacks management evidence from randomized trials. We aimed to evaluate whether the association between endovascular treatment (EVT) and outcomes in iPCAO acute ischemic stroke is modified by initial stroke severity (baseline National Institutes of Health Stroke Scale [NIHSS]) and arterial occlusion site.

Methods: Based on the multicenter, retrospective, case-control study of consecutive iPCAO acute ischemic stroke patients (PLATO study [Posterior Cerebral Artery Occlusion Stroke]), we assessed the heterogeneity of EVT outcomes compared with medical management (MM) for iPCAO, according to baseline NIHSS score (≤6 versus >6) and occlusion site …

Language Discrimination Using Bilingual Picture Exchange For Culturally And Linguistically Diverse Children With Autism Spectrum Disorder, River Waits

LSU Doctoral Dissertations

Recent research suggests that one-fifth of United States households use non-English languages in the home setting. Ethically and effectively supporting culturally and linguistically diverse (CLD) clients (e.g., autistic individuals) presents a growing challenge to practitioners of Applied Behavior Analysis (ABA). Though efforts to address the linguistic needs of the population have grown in recent years, current literature focuses on language selection for monolingual services and underemphasizes the need for bilingual service provision. Studies were conducted to (I) evaluate the efficacy of bilingual picture exchange (i.e., mand response) across items, speakers, and languages (i.e., English and Spanish) as well as (II) …

Psychology Faculty Research and Publications

Background

Childhood abuse (physical, emotional, and sexual) is associated with aberrant connectivity of the amygdala, a key threat-processing region. Heightened amygdala activity also predicts adult anxiety and posttraumatic stress disorder (PTSD) symptoms, as do experiences of childhood abuse. The current study explored whether amygdala resting-state functional connectivity may explain the relationship between childhood abuse and anxiety and PTSD symptoms following trauma exposure in adults.

Methods

Two weeks posttrauma, adult trauma survivors (n = 152, mean age [SD] = 32.61 [10.35] years; women = 57.2%) completed the Childhood Trauma Questionnaire and underwent resting-state functional magnetic resonance imaging. PTSD and anxiety …

Do Private Actors Have Rights Under The Wto? The Motivation For And (Inadequate) Implementation Of Gatt Article X, Adeet Dobhal, Petros C. Mavroidis, Lucas Moreira Jiminez, Sunayana Sasmal, Robert Wolfe

Faculty Scholarship

General Agreement on Tariffs and Trade (GATT) Article X has been consistently overlooked in literature even though it is a unique provision in the GATT-regime: it acknowledges standing for private actors who can challenge trade-related administrative action by World Trade Organization (WTO) members. This provision is an unusual instantiation of the need to provide transparency for private actors about state policy. It is equally eccentric in seeming to provide a right for private actors to challenge governments, albeit only before domestic fora. How did the GATT end up with this provision? And are these apparent private rights meaningful in practice? …

Systemic Regulation Of Artificial Intelligence, Yonathan Arbel, Matthew Tokson, Albert Lin

Articles

Today's artificial intelligence ("AI") systems exhibit increasing capabilities across a remarkable variety of tasks. The rapid growth in AI ability has caught the attention of policymakers, parliaments, and the United Nations. These entities are increasingly looking towards regulating AI, not only in its particular applications, but as a technology. Yet legal scholarship has thus far offered little to this new and critical regulatory conversation, which has instead been dominated by computer scientists and technologists.

This Article begins the project of assessing AI's broader risks and law's role in addressing them. These risks are wide ranging -they span harms to vulnerable …
