Interpersonal Theory Of Suicide In A Mild Traumatic Brain Injury Sample, Janelle Wee

Clinical Psychology Dissertations

Mild traumatic brain injury (mTBI) is associated with cognitive and emotional changes that may increase suicide risk. This study, grounded in the Interpersonal Theory of Suicide (IPTS), examined whether premorbid functioning moderates the relationship between cognitive functioning (working memory and processing speed) and suicidal desire (thwarted belongingness and perceived burdensomeness) in individuals with mTBI. Participants (n = 54) were drawn from a clinical neuropsychological sample and completed the WAIS-IV, TOPF, BDI-II, and Interpersonal Needs Questionnaire (INQ). Hierarchical moderated regression analyses were conducted across 100 multiply imputed datasets. Depressive symptoms were included as a covariate. Results showed that depressive symptoms …

Social Support Networks’ Influence On First-Generation Professionals’ Career Success, Melissa-Ann M. Lagunas

Clinical Psychology Dissertations

This dissertation examines how perceived social support influences career success among first-generation professionals (FGPs)—individuals who are first in their families to pursue white- collar careers. Drawing on Seibert et al.'s (2001) Social Capital Theory of Career Success, I investigate direct and indirect pathways through which social support affects three dimensions of career success: sense of belonging, professional flourishing, and career satisfaction, while exploring mediating roles of perceived support network quality and resilience. A sample of 230 FGPs (Mage = 31.9 years, SD = 5.32) completed a 62-item online survey hosted on Qualtrics. Participants represented diverse professional disciplines classified into five …

The Impact Of Coping Strategies On The Perceived Stress And Well-Being Of People With Disabilities During The Covid-19 Pandemic, Angela G. Maccarrone

Clinical Psychology Dissertations

The COVID-19 pandemic significantly and negatively impacted those around the world, particularly marginalized groups such as people with disabilities (PWDs). What remains unclear from existing published research is the exact relationship between perceived stress of the pandemic, coping, and overall well-being in PWDs. Prior research and theoretical models of coping suggest that active coping processes are associated with more positive outcomes versus avoidant coping strategies, which have shown less favorable outcomes on well-being. Due to the varying ways in which the pandemic affected PWDs, coping might serve as a moderator, amplifying the negative relationship between perceived stress and well-being. Building …

Cutaneous Cytomegalovirus In Mixed Serostatus Kidney Transplant Patient, Dominic Finan, Vaibhav Garg, Lucjan Lang, Tricia Royer, Katherine Belden, Sherry Yang

Department of Dermatology and Cutaneous Biology Faculty Papers

Cutaneous cytomegalovirus infection is a rare but serious complication in solid organ transplant recipients. We present a 47-year-old male kidney transplant recipient with a chronic, nonhealing right lower extremity ulcer. Initial biopsies revealed septic vasculopathy, leading to treatment with sodium thiosulfate and antibiotics for suspected calciphylaxis. Despite regular wound care, the ulcer continued to worsen. After completing 6 months of cytomegalovirus prophylaxis, surveillance viral levels remained undetectable, but the ulcer progressed considerably. Worsening severity prompted hospitalization, during which cytomegalovirus viremia was detected, and an ulcer biopsy confirmed cytomegalovirus inclusion bodies. Antiviral therapy was reinitiated, resulting in rapid and sustained wound …

Reconciling Jekyll And Hyde: The Future Of Masculinity Research Within The Domestic Violent Extremism Context, Sam T. Hunter, Brett H. Neely, Carter Welch, Amanda N. Moeller

Department of Management: Faculty Publications

Violence among young men in the United States has escalated in recent years, leading to two contrasting perspectives of young men—either as (a) agentic aggressors or (b) by-products of societal shifts that have caused disadvantage. The first perspective characterizes men as entitled and reactionary, prone to aggression when their societal expectations are unmet. This view aligns with the frustration-aggression hypothesis in which unmet desires lead to hostile behaviors, particularly among individuals who perceive a loss of status and significance. Conversely, the second perspective views men as victims of rapid societal changes, such as job displacement, educational disparities, and shifting gender …

A Conceptual View Of Data For Decision-Oriented Databases: A Knowledge-Driven Approach, Sung-Kwan Kim, Wenjun Wang, Seunghyun Kim

Journal of International Technology and Information Management

Typical database design goes through three levels of data modeling: conceptual modeling, logical modeling, and physical modeling. In particular, conceptual modeling is important since it captures and documents user data requirements. Conceptual modeling serves as a blueprint for designing a database by defining information content to be included in a database. Presently, decision-oriented databases have no well-accepted conceptual modeling approach to apply. While some use conceptual modeling approaches for transaction-oriented databases such as the ER (Entity-Relationship) model, they are not well-suited for decision-oriented databases. It is hard to map from the ER Model to decision-oriented data models. Others attempt to …

Still Making It Up As He Goes: Revisiting The Hyper-Rhetorical Presidency In Trump’S Second Term, Richard Holtzman

Politics, Law, and Society Faculty Journal Articles

In Fast Capitalism’s 2020 issue, “This is Not Normal,” I explored Trump’s propensity for improvised rhetoric during his first term; that is, his reliance on “making it up as he goes” in his public statements, whether communicated verbally or through social media. The primary goal of my original essay was not simply to identify the president’s ad-hoc communication style—which is clear for all to see—but to argue that the president’s tendency toward improvisational speech matters because it represents more than just his approach to communication. This tendency toward improvisation also constitutes much of his approach to governing.

In “Making It …

Saudi Medical Journal

Objectives: To assess the clinical course and long-term outcomes of complicated and uncomplicated AM in Saudi Arabia. Acute myocarditis (AM) can have different presentations and outcomes based on different factors, one of which is left ventricular ejection fraction (LVEF). Methods: Data from 382 patients with suspected AM, admitted between January 2016 and October 2023, were reviewed. Clinical course, in-hospital complications, and all-cause mortality were evaluated in both the acute and follow-up phases. Outcomes were compared between 2 groups: LVEF <50% (n=43); and normal LVEF (≥50% [n=41]) at presentation. Results: Data from 84 patients (mean [±SD] age, 33.5±10.2 years; 26.2% female) who fulfilled the inclusion criteria were analyzed. The most common symptom was chest pain (83.3%) and 11 (13.1%) patients had fulminant presentation. ST-T changes were found on electrocardiography in 45.2% of patients. The mean LVEF was 46±12.4% at presentation. Patients in the LVEF <50% group were significantly more likely to experience a first-time cardiac-related adverse event (CRAE) (hazard ratio 2.6 [95% confidence interval 1.1–6.2]; p =0.031) with a mean time of 38.8±3.8. The all-cause in-hospital and follow-up mortality rates in the LVEF <50% group were 4.7% (one-half cardiac-related) ( p =0.494) and 4.7% (all cardiac-related) ( p =0.494), respectively. Conclusion: Of 84 patients diagnosed with AM, those with LVEF <50% were more likely to experience first-time CRAEs and exhibited low short- and long-term mortality rates.

Predictors Of Hypoglycemia Among Children Admitted In The Emergency Pediatric Unit Of The University Of Maiduguri Teaching Hospital, Maiduguri, Nigeria, Ruqayyatu A. Imam, Hassan A. Elechi, Hauwa Y. Musa, Adamu I. Rabasa, Habiba B. Bakari

Saudi Medical Journal

Objectives: To determine the prevalence and pattern of hypoglycemia among children admitted to the Emergency Pediatric Unit (EPU) at the University of Maiduguri Teaching Hospital, Maiduguri, Nigeria. Methods: A cross-sectional study was conducted between February and September 2020. Blood glucose, along with other relevant laboratory investigations, was measured for each patient upon admission to the EPU using a point-of-care test glucometer (ACCU-CHEK with strips). Results: Of the 340 children recruited for the study, 54 patients had hypoglycemia (<2.2 mmol/L), giving a prevalence rate of 15.9%. Thirty-six (66.7%) of the children with hypoglycemia were under the age of 5 years (odds ratio [OR]: 6.218 [1.077–35.912], p =0.041) and 26 (48.1%) were severely underweight (OR: 3.692 [1.266–10.971], p =0.017). Factors such as not having eaten for at least 16 h, weakness, and coma at presentation all independently predicted hypoglycemia (OR: 5.696 [1.768–18.352], 6.556 [1.730–24.850], 9.479 [3.092–29.059], p =0.004, 0.006 and <0.001) respectively. Severe malaria was also independently related to hypoglycemia (OR: 2.720 [0.554–13.365], p =0.021). Conclusion: Hypoglycemia is a common occurrence among children admitted to the EPU. Factors such as being under five years old, in a coma, weakness, severe malaria, and prolonged fasting were all identified as independent predictors of hypoglycemia. Therefore, routine blood glucose monitoring of children admitted to the EPU, specifically those at higher risk, is recommended.
