Patients undergoing immune effector cell therapy (IECT) are at high risk for infections. We assessed seropositivity against pneumococcus, tetanus, and diphtheria in patients before and after IECT and the patients' response to vaccination. We enrolled patients who underwent IECT from January 2020 to March 2022. Antibody levels for diphtheria, tetanus, and pneumococcus were measured before IECT, at 1 month, and 3-6 months after. Eligible patients were vaccinated after IECT. In non-seroprotected patients, we discontinued testing. Before IECT, most patients had seroprotective antibody levels against tetanus (68/69, 99%) and diphtheria (65/69, 94%), but fewer did against pneumococcus (24/67, 36%). After IECT, …

Self-efficacy or how students feel about their learning is also an important factor in literacy retention and performance. The setting for this study was inner-city Northern Virginia. In this study, 163 fourth and fifth grade elementary students in …

Wisdom City: Towards A Political Reading Of The Wisdom Genre, James E. Golec Jr.

Doctoral Dissertations and Projects

The contemporary conversation surrounding the wisdom genre shows a lack of consensus regarding the origin, nature, and biblical use of wisdom. This situation can be improved through reading the biblical wisdom genre politically, revealing the principles that create and sustain a God-fearing society. The hermeneutical key to accomplish this task begins with the claim that the book of Proverbs presents itself as a ‘city in a book.’ The outline of Proverbs, especially via the first nine chapters, introduces coherence between the concept of wisdom and an archetypal city. Second, the book provides a transformative engine, which can be found in …

Participants completed a demographic questionnaire, the Servant Leadership Questionnaire (Liden et.al, 2008), Work Environment Scale (Tsai et al.,2015), and Mental Health Continuum Short Form (Keyes, 2002). A series of regression analyses were conducted to understand the relationship between …

Human And Sex Trafficking: A Quantitative Examination Of The Knowledge And Awareness Of The College-Aged Population, Margaret Caroline Weiker

Doctoral Dissertations and Projects

It is crucial for the public and more specifically those who are a part of vulnerable populations to understand the dangers of both human and sex trafficking. One sub-group of vulnerable populations that are likely to encounter a trafficking situation are college students, as many of these students are unaware of trafficking’s prevalence. While there have been studies of specific populations with prior specialized knowledge, there is little information on the knowledge, perceptions, and awareness levels of the general college-aged population. This study will be quantitatively structured into a two-part survey, seeking to collect data from a sample size of …

Measuring Technical Super-Efficiency Of Christian Faith-Based International Humanitarian Organizations, Barbara G. Price

Doctoral Dissertations and Projects

COVID-19 left a wake of destruction upon its descension, pervasion, and diffusion across the continents. Not only did this happen at individual, household, and corporate levels, but also the nonprofit world. Christian ministries, faith-based organizations, and faith-based charities are among some of the largest international relief and development agencies that are on the front lines of humanitarian and disaster relief efforts (MinistryWatch & Smith, 2023). Understanding the effects of COVID-19 or phenomena with similar magnitudes on faith-based organizations is critical to understanding the impact at the level of their international humanitarian development and relief programs. There is a need for …

If The Balloon Goes Up: A History Of U.S. Army Maneuvers And Their Effectiveness, 1902-1944, Randall S. Wells Jr.

Doctoral Dissertations and Projects

The historiography surrounding U.S. Army military readiness exercises and their effectiveness in improving or increasing the resultant fighting power of Army Ground Forces is an untouched field of study. This work fills that historical gap by exploring and analyzing a series of U.S. Army readiness maneuvers conducted for forty-plus years that sought to closely replicate the actual conditions of combat that Army Ground Forces were expected to encounter. In doing so, it reveals the criticality of ensuring effective military readiness exercises accomplish their primary intent, which is to use actual military vehicles, aircraft, naval vessels, weapons, and tactics to facilitate …

Research outputs 2022 to 2026

To comply with the trend of emission reduction and energy-saving in the industrial sector, a novel integration of the hydrogen liquefaction process based on reversed Brayton cycle (RBC) with the organic Rankine cycle (ORC), for waste heat recovery is proposed. The high temperature gas in the compressor outlet of RBC, which is typically wasted in air-coolers, is recovered in ORC and used as the heat source for power generation for the hydrogen liquefaction process. Thermodynamic analysis showed that compared to the conventional system COP increased by 17.95% from 0.11 to 0.14 and specific energy consumption (SEC) decreased by 16.33% from …

Explainable Ai For Autism Diagnosis: Identifying Critical Brain Regions Using Fmri Data, Suryansh Vidya, Kush Gupta, Amir Aly, Andy Wills, Emmanuel Ifeachor, Rohit Shankar

Peninsula Medical School

Early diagnosis and intervention for Autism Spectrum Disorder (ASD) has been shown to significantly improve the quality of life of autistic individuals. However, diagnostics methods for ASD rely on assessments based on clinical presentation that are prone to bias and can be challenging to arrive at an early diagnosis. There is a need for objective biomarkers of ASD which can help improve diagnostic accuracy. Deep learning (DL) has achieved outstanding performance in diagnosing diseases and conditions from medical imaging data. Extensive research has been conducted on creating models that classify ASD using resting-state functional Magnetic Resonance Imaging (fMRI) data. However, …

Nonpoint Source Pollution Risk Mapping For Alabama’S Big Creek Lake, Marco Allain, Jason Jones

The Geographical Bulletin

Big Creek Lake is the primary water supply for Mobile, Alabama. Management of the watershed is important because nonpoint source (NPS) pollution can introduce contaminants into the lake. After the Mobile Area Water and Sewer System (MAWSS) expressed a need for a land suitability assessment to aid in mitigating NPS pollution in the watershed, we worked to assist them in mapping potential sources of NPS pollution there. First, we created a system for rating the relative contributions of various land cover and soil types to NPS pollution in the watershed. Then, we utilized land use/land cover information generated from ASTER …
