Enhancing Patient-Centered Care Through Predictive Modeling To Optimize Appointment Scheduling In Pediatric Care, Linda Anna Penitusi-Burford

Doctor of Business Administration (DBA)

This study evaluated the predictive performance of three forecasting models—Autoregressive Integrated Moving Average (ARIMA), Prophet, and Long Short-Term Memory (LSTM)—to determine which most accurately forecasts pediatric appointment availability. The research was guided by the theory that accurate forecasting can enhance healthcare scheduling by aligning appointment supply with patient demand, thereby advancing patient-centered care (PCC).

A quantitative, comparative design was employed using two years of pediatric online scheduling records. The methodological framework incorporated multiple forecast horizons (30–180 days) and statistical analyses, including ANOVA, paired sample t-tests, and regression. Model performance was assessed using standard error metrics: Mean Absolute Error (MAE), Mean …

Medium Matters: Reading Comprehension Differences Between Print And Digital Texts In High School, Doyle Huelsman

Doctor of Education (EdD)

An increasing reliance on digital devices in public schools has raised questions about how reading medium influences student comprehension. Although digital texts offer logistical and financial advantages, prior research suggests that students may comprehend printed text more effectively. This exploratory quasi-experimental study examined whether ninth-grade students’ comprehension differed when reading a grade-level passage in print or on a digital screen in intact classroom settings. The study also investigated whether subgroup characteristics moderated any medium-related effects.

A total of 334 students enrolled in a general education English course participated. Fourteen classrooms were randomly assigned to print or digital conditions. All students …

The Relevance Of Dnajb1 Protein Dimerization Against The Human Neurodegenerative Diseases, Erina Kotreli, Trang Le, Szymon Ciesielski

Dean's Leadership Council Library Research Prize

All biological functions in living organisms depend on the activity of proteins, long molecules that must twist and fold into specific shapes to become functional. A subset of proteins known as molecular chaperones is essential for maintaining cellular health by assisting other proteins in folding correctly and refolding those damaged by stress. When proteins misfold and clump together, they can form toxic aggregates linked to many neurodegenerative diseases, including Alzheimer’s disease (AD), one of the leading causes of death in the United States. In AD, these protein aggregates form organized, elongated structures referred to as amyloid-like fibrils, which damage neurons …

Background: Education is strongly associated with cognitive outcomes at older ages, yet the extent to which these associations reflect causal effects remains uncertain due to potential confounding. Methods: Leveraging changes in historical measures of state-level education policies as natural experiments, we estimated the effects of educational attainment on cognitive performance over 10 years in 20,248 non-Hispanic Black and non-Hispanic White participants, aged 45+ in the Reasons for Geographic and Racial Disparities in Stroke cohort (2003-2020) by (1) using state- and year-specific compulsory schooling laws, school-term length, attendance rate, and student-teacher ratio policies to predict educational attainment for US Census microsample …

Educators’ Perceptions Of The Components That Influence Student Behavior And The Impact Restorative Practices And Community Circles Have On Improving Overall Well-Being In Students, Catherine Dulovic

Selected Full Text Dissertations, 2011-

Restorative Practices have been utilized in many schools as an alternative to traditional disciplinary methods. Traditional methods such as Out of School Suspension (OSS) and In-School Suspension (ISS) can lead to feelings of isolation and impact students’ attitudes towards school and community. Community Circles are often used in conjunction with Restorative Practices to support the development of the whole child, build relationships, promote positive discipline, and create a trauma sensitive environment that includes mindfulness practices. The current research examined educators’ perspective of the components that influence student behavior and the impact Restorative Practices and Community Circles have on improving behavior …

Indirect Earnings Management, Scott B. Jackson, Jason T. Rasso, Aaron F. Zimbleman

Faculty Publications

We hypothesize that managers use their hierarchical role as reviewers of accounting judgments and estimates to manage earnings, which we call indirect earnings management (IEM). Across a series of experiments using highly experienced financial executives as participants, we provide evidence that IEM (1) is likely used by managers to achieve current and future earnings targets, (2) reduces both cognitive dissonance associated with managing earnings and the extent to which managers think that their behaviors constitute earnings management, and (3) is more likely to be used when corporate governance is strong than when corporate governance is weak. The results of this …

Affordance-Based Information Technology Sensemaking [Abits], Arvin Mesgari, Chitu Okoli, Ana Ortiz De Guinea

Information Systems and Business Analytics Faculty Works

Information Technology (IT) use gives rise to a wide variety of outcomes. This stems in part from the divergent ways in which individuals understand technology. While the sensemaking literature unveils how meaning is attached to organizational phenomena via cognitive and social processes, it overlooks the discovery dimension of making sense, that is detecting the role of the IT artifact in bringing about outcomes. In other words, there is a need to explain how the IT artifact contributes to technology sensemaking and its outcomes. This paper presents a framework that enables scholars to analyze the IT artifact’s role in technology sensemaking …

The Moderating Role Of Hospital Staffing Levels On The Effectiveness Of Clinical Decision Support Systems In Mitigating Patient Readmission Rates, Youyou Tao, Arindam Brahma, Kevin Baldwin, Rui Sundrup, Dezhi Wu

Information Systems and Business Analytics Faculty Works

Healthcare staffing shortages and high 30-day readmission rates are pressing challenges in today's healthcare systems. While extensive studies have explored the positive impact of Health Information Technology (HIT) on health outcomes, the effect of hospital staffing on HIT effectiveness, particularly Clinical Decision Support Systems (CDSS), is underexplored. Therefore, we examine whether physician and resident staffing levels moderate the impact of CDSS on 30-day readmission rates. After analyzing data from 1,605 hospitals in the United States from 2017 and 2018, we found that the effect of CDSS implementation in reducing 30-day readmission rates is more pronounced in hospitals with lower bed-to-physician …

A Preliminary Program Evaluation: Rates Of Intimate Partner Violence In An Urban Child Welfare Prevention Program, Athena Roca

PCOM Psychology Dissertations

Intimate partner violence (IPV) remains a pervasive public health concern with significant consequences for families. Traditional batterer intervention programs (BIPs), which often focus solely on the person causing harm (PCH), have demonstrated limited success in reducing recidivism, particularly when grounded in punitive or authoritarian models. This study evaluated the Child-Welfare IPV Prevention Program (CWIPVPP), a family-centered, trauma-informed intervention that engages the PCH, co-parents, and children to reduce IPV-related behaviors and promote healthier family functioning.

Recidivism indicators, including domestic violence incident reports (DIRs) and arrests, were analyzed for 57 fathers referred to the program, with 53 retained for final analyses. A …

Targeting Rna Polymerase I In Ewing Sarcoma Treatment, Alexis Bruce, Gavin Anchondo, Rebekah Carter, Sergio Guerrero Pacheco, Hema Sri Kambala, Elizabeth Cortez, Kyra Parker, Le Su

Research, Publications & Creative Work

Ewing sarcoma (ES) is a high-grade bone and soft tissue tumor in adolescents and young adults. Cytotoxic chemotherapy does not improve prognosis, especially for advanced ES patients who have a 5-year survival of 30% or less [1, 2]. Molecular targeted therapy emerges as a promising strategy to battle ES, given its unique driver mutations resulting from the fusion of the EWS and one of the ETS genes, but the feasibility of directly blocking EWS-ETS function has not yet been established [3]. To search for new therapeutic targets, we began with an analysis of the Cancer Dependency Map (DepMap) datasets that …

Highly effective antiretroviral-based HIV prevention plays an important role in ending the global HIV/AIDS epidemic. However, the sustainable control of the epidemic is hampered by unequal access to prevention options, including HIV testing, alongside with drug resistance and ongoing barriers to accessing sustainable HIV treatment. Therefore, an HIV vaccine, combined with effective prevention and treatment, remains an absolute necessity to control the epidemic. Yet, the recent discontinuation of four major vaccine efficacy studies is raising concerns about the future of HIV vaccine research and development globally, and particularly in the European region where funding for vaccine research and development has …

Gut inflammatory diseases cause microbial dysbiosis. Human immunodeficiency virus-1 (HIV) infection disrupts intestinal integrity, subverts repair/renewal pathways, impairs mucosal immunity and propels microbial dysbiosis. However, microbial metabolic mechanisms driving repair mechanisms in virally inflamed gut are not well understood. We investigated the capability and mechanisms of gut microbes to restore epithelial barriers and mucosal immunity in virally inflamed gut by using a multipronged approach: an in vivo simian immunodeficiency virus (SIV)-infected nonhuman primate model of HIV/AIDS, ex vivo HIV-exposed human colorectal explants and primary human intestinal epithelial cells. SIV infection reprogrammed tryptophan (TRP) metabolism, increasing kynurenine catabolite levels that are …

Exposure to endocrine-disrupting chemicals such as phthalates may increase risk of hypertensive disorders of pregnancy (HDP). Prior studies lack investigation of chemical mixtures, phthalate replacements, or key periods of susceptibility including early pregnancy. In the present study, we used a longitudinal approach to evaluate gestational exposure to phthalates and replacements, as both single-pollutants and mixtures, in association with blood pressure and diagnosis of preeclampsia or any HDP. The Human Placenta and Phthalates prospective pregnancy cohort includes 291 participants recruited from two U.S. clinics. Urinary metabolites of ten phthalates and replacements were quantified at up to 8 time points per individual …

This was a cross-sectional analysis of county-level data in the United States from January 2018 to December 2021. Using the level of maternity care access, we categorized counties into desert, low access, moderate access, and full access. The primary outcome of interest was maternal mortality rate per 100,000 live births. A secondary outcome was pregnancy-related mortality rate per 100,000 live births. Absolute risk differences and adjusted incidence rate ratios were calculated for maternal mortality and pregnancy-related mortality with multivariable negative binomial mixed-effects …

Methodological And Clinical Concerns In The Study On Postpartum Hypertension Management, Takaki Tanamoto, Kyosuke Kamijo, Yusuke Tsutsumi, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

[Introduction] We read with interest the recent study by Rosenfeld et al.¹ However, we have several clinical and methodological concerns about this study.¹

First, this study's propensity score matching (PSM) lacked key clinical confounders, including perinatal risk factors and the highest systolic/diastolic blood pressures. Smoking, alcohol use, and multifetal gestation, which influence blood pressure during pregnancy,²,³ potentially affect both primary and secondary outcomes. Additionally, the authors did not report standardized mean differences before and after PSM, which are essential for assessing balance.⁴
