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.

Plasmonic Down-Shifting Layers For Cylindrical Solar Concentrators, Kenneth Coldrick

Doctoral

The efficiency of photovoltaics (PVs) and photo-thermal (PT) systems is hindered by spectral mismatches and low thermal conductivity. A promising solution to address these issues can be the use of luminescent down-shifting (LDS) layers. This involves the incorporation of luminophores into solid or liquid layers that will act as spectral beam splitters (SBSs). In solid polymers, they form luminescent solar concentrators (LSCs), while in liquids, they act as working fluids and SBS for hybrid photovoltaic-photothermal (PVT) systems. This thesis will examine the energy conversion in both solid and liquid configurations through experimental, simulation, and economic analyses. An open-source model that …

Inactivation Of Zika Virus With Hydroxypropyl-Beta-Cyclodextrin, Cory R. Hewitt, Nicholas J. Wixon, Arthur Gallegos, You Zhou, Victor C. Huber, M. Scott. Killian

Nebraska Center for Biotechnology: Faculty and Staff Publications

Background/Objectives: Zika virus (ZIKV) infection is associated with life-threatening diseases in humans. To date, there are no available FDA-approved therapies or vaccines for the specific treatment or prevention of ZIKV infection. Variation in the ZIKV envelope protein (Env), along with its complex quaternary structure, presents challenges to synthetic approaches for developing an effective vaccine and broadly neutralizing antibodies (bnAbs). We hypothesized that beta-cyclodextrin (BCD) could be used to uniquely inactivate infectious ZIKV without disruption of Env.

Methods: ZIKV was propagated in Vero cells and admixed with BCD. The BCD-treated ZIKV was evaluated for infectivity using immunofluorescence and quantitative …

Microscopic Analysis Of Temperature Effects On Surface Colonization And Biofilm Morphology Of Salmonella Enterica, Zachariah Vice, You Zhou, Sapna Chitlapilly Dass, Rong Wang

Nebraska Center for Biotechnology: Faculty and Staff Publications

Salmonella enterica represents a diverse group of pathogens commonly associated with food contamination including red meat. Even though pre- and post-harvest cleaning and sanitization procedures are widely implemented at meat processing plants to mitigate the hazard, S. enterica cells may escape the process by colonizing, on contact, surfaces in the form of a biofilm that functions as an aggregated microbial community to facilitate mutual protection, antimicrobial resistance, proliferation and dissemination. Biofilm development is a complex process that can be affected by a variety of factors including environmental temperature. We developed methods using scanning electron microscopy and confocal microscopy with a …

Digital Journal of Clinical Medicine

The FDA approved Semaglutide (Wegovy™) on August 15, 2025, for adults with MASLD and moderate to advanced fibrosis (F2–F3), making it the second approved therapy after Resmetirom. MASLD affects up to 38% of adults and is now the leading cause of liver disease. In the phase 3 ESSENCE trial, Semaglutide achieved resolution of steatohepatitis without worsening fibrosis in 62.9% versus 34.3% with placebo, with additional benefits in weight loss and glycemic control. While long-term data remain pending and access barriers exist, this approval marks a significant advance in MASLD therapy with meaningful histologic and metabolic improvements.

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

Skin Color Cannot Be Confined To Six Categories: Comparing The Fitzpatrick Scale And Colorimetric Measures, Henry Lim, Kristina Kafle, Reem Ayoub, Dana Olsen, Ysabelle Martinez, Rafael Do Valle, Christina Guo, Marshall Hall, Christian Scheufele, Michael Carletti, Stephen E. Weis

North Texas Research Forum 2025

Purpose The Fitzpatrick Scale (FS), originally developed to dose photochemotherapy in Caucasian skin, has become widely adopted for skin color categorization. It originally included types I-IV, with types V-VI added later for darker skin. The FS was designed for UV radiation reactivity assessment. However, it is increasingly used as a proxy for objective skin color classification, despite being based on a subjective questionnaire. Individual Typology Angle (ITA), a validated colorimetric measurement, presents a potential alternative. Previous studies examining these classification systems have been limited by small sample sizes and uneven distribution across skin tones with subjects predominantly having lighter skin …
