A Leslie System For A Demographic Simulation: From An Actuarial Point Of View, David Kings

Electronic Theses and Dissertations

This thesis develops a discrete stochastic linear systems interpretation of age–stage demographic evolution grounded in Leslie operators and realized in a discrete-event simulation implemented with salabim. The central claim is that one annual cycle of the simulation constitutes a cone-preserving, stochastic affine transformation on a high- dimensional population state vector indexed by age, sex, marital status, household type, employment, and education, and that the composition of yearly operators yields a random matrix product whose top Lyapunov exponent is the stochastic counterpart of the Perron–Frobenius growth rate (Caswell, 2001; Tuljapurkar, 1997)[1, 2]. The actuarial bridge is constructed by mapping simulated survival …

In this Doctor of Nursing Practice (DNP) project, I focused on a staff education initiative to improve nurses' knowledge to reduce disproportionately high rates of hypertension, complications, and mortality due to factors such as limited access to care, medication nonadherence, mistrust of providers, and improve on culturally competent interventions. The guiding practice-focused question was: Does educating nurses on hypertension in the African American population improve …

Preventing Psychotropic Medication Duplication: Improving Communication Between Primary Care And Psychiatric Providers, Linda Nwachuku

Walden Dissertations and Doctoral Studies

This project is an education-based initiative designed to address the persistent problem of psychotropic medication duplication in integrated care settings. Duplication occurs when patients receive multiple prescriptions of the same or similar psychotropic drugs. The practice gap exposes patients to adverse drug events, complications of polypharmacy, and reduced adherence, and subjects the providers to liability. The practice-focused question guiding this project is: For primary care and psychiatric providers, will an education program on structured communication and medication reconciliation, compared to current usual practices, increase provider confidence and awareness of the risks of duplication, communication strategies, and increased the use of …

The Impact Of Top Management Team Heterogeneity On Corporate Green Innovation, Xueyan Luo

Dissertations and Theses Collection (Open Access)

At present, green innovation has become a key path for enterprises to achieve sustainable competitive advantage. However, existing research pays limited attention to how internal governance factors—especially top management team (TMT) heterogeneity—affect green innovation. Based on Upper Echelons Theory, managerial cognition theory, and institutional theory, this paper constructs a framework of “TMT heterogeneity–green strategic orientation–green innovation,” and explores the impact of different types of heterogeneity and the moderating role of regional innovation environments. Heterogeneity is categorized into conflict-type (gender, age, financial background) and complementary-type (educational, professional, overseas background) to better explain its mechanisms.

Research On The Impact Mechanism Of The Development Level Of Smart Agriculture On Farmers' Income, Baoping Liu

Dissertations and Theses Collection (Open Access)

Agriculture is a fundamental and strategic industry essential to national food security and farmers’ well-being. Faced with global population growth, climate change, and resource constraints, the traditional high-input agricultural model is unsustainable. Smart agriculture, empowered by IoT, big data, and AI, has become critical for agricultural transformation and sustainable development. However, existing research overemphasizes technical efficiency and neglects how smart agriculture systematically affects farmers’ income, especially its transmission mechanism and regional heterogeneity.

Against China’s rural revitalization and digital village strategy, this study investigates how smart agriculture development influences farmers’ income, using a hybrid framework of macro empirics and micro analysis. …

Journal of Youth Development

Millions of American adolescents have experienced the developmental consequences associated with parental incarceration. Positive youth development activities, including sports team participation, could buffer some of the risks of parental incarceration. Research on sports involvement among adolescents impacted by parental incarceration is scant and suggests their participation may be limited, though a significant body of research among adolescents in general demonstrates sports team participation is associated with better outcomes. We addressed important gaps in research by 1) estimating the prevalence of sports team participation among adolescents impacted by parental incarceration, 2) examining whether sports team participation differed by socioeconomic status in …

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by persistent deficits in social communication and interaction, as well as restricted, repetitive patterns of behavior, interests, or activities. These features are associated with atypical early brain development and connectivity. While ASD has been traditionally associated with molecular genetic alterations, recent research highlights the significant contribution of various environmental factors to the pathophysiology of the disorder. Pathogenic genetic variations in key regulatory genes remain central to ASD risk; however, environmental influences such as advanced maternal or paternal age, poor maternal health during pregnancy, gestational diabetes mellitus, alterations in the early-life …

Precision-Weighted Federated Learning, Jonatan Reyes, Lisa Di Jorio, Cecile Low-Kam, Marta Kersten-Oertel

Computer Science Faculty Publications

Federated learning (FL) using the federated averaging (FedAvg) algorithm has shown great advantages for large-scale applications that rely on collaborative learning, especially when the training data is either unbalanced or inaccessible due to privacy constraints. We hypothesize that FedAvg underestimates the full extent of heterogeneity of data when the aggregation is performed. We propose Precision-Weighted Federated Learning (PW) a novel algorithm that takes into account the second raw moment (uncentered variance) of the stochastic gradient when computing the weighted average of the parameters of independent models trained in a FL setting. With PW, we address the communication and statistical challenges …

Louis William Valentine Dubourg: His First Years As Bishop Of Louisiana, John E. Rybolt C.M.

Vincentian Studies

Louis William Valentine Dubourg, a priest of the Society of Saint Sulpice, invited the Vincentians to establish a seminary for his diocese of Louisiana. Part of his fundraising efforts to support these and other works was this booklet, The Notice sur l’état actuel de la Mission de la Louisiane (Notice Concerning the Current State of the Mission of Louisiana). Printed in 1820, it circulated widely in Europe and was corrected, updated, and reprinted twice in 1822. Transcriptions given here illuminate differences between the editions. The booklet’s author is anonymous but is probably Charles de la Croix, the bishop’s secretary. The …
