A System Dynamics Model For Analyzing Customer Satisfaction Drivers In A Manufacturing Context, Mahnaz Asgari Sooran, Venkat Allada, Adewole Adegbola

Engineering Management and Systems Engineering Faculty Research & Creative Works

Customer satisfaction offers economic benefits and competitive advantage to manufacturing enterprises. However, a gap exists in understanding how to achieve customer satisfaction due to the complexities involved in coordinating various subsystems of an enterprise in an efficient manner. In this paper, we identified four internal and external-to-the-firm customer satisfaction drivers which include: government policies, supply chain reliability, knowledge management, and manufacturing performance criteria such as on-time delivery, quality and cost. We then developed a conceptual framework to define the non-linear mathematical relationships between drivers using system dynamics modeling. We conducted "what-if "scenario analyses for a base case, optimistic case and …

Existence And Uniqueness Of Positive Solutions For Hilfer–Hadamard-Type Fractional Differential Equations With Γ-Concave And Sub-Homogeneous Operators, Hasan Rasouli, Hojjat Afshari, Martin Bohner

Mathematics and Statistics Faculty Research & Creative Works

In this research, we present necessary and sufficient conditions for the existence and uniqueness of positive solutions for a class of Hilfer–Hadamard-type fractional differential equations with boundary value problems, including those with integral boundary conditions. The obtained results are conditional on a specific set of strong assumptions, which substantially narrow the class of admissible nonlinearities, coefficients, and boundary data. Thus, the present work extends the Hadamard-type framework to the Hilfer–Hadamard setting only within this restrictive regime, rather than providing a full extension to all Hilfer–Hadamard systems. We utilize the properties of (Formula presented.) -concave and sub-homogeneous operators along with two …

Deepfakes As Crisis Triggers: Experimental Evidence On Response Strategy Effectiveness, Responsibility Attributions, And Sharing Intentions, Alicia Mason, Mariah Laman, Tanner Glenn, Treyton Meyers

Faculty Submissions

The term deepfake refers to falsified media content created using artificial intelligence (AI) technologies to manipulate audio, video, or images. Deepfake news fabrications are designed to appear highly realistic, making it difficult for audiences to distinguish them from authentic content. Responding to deepfake-induced  reputational threats therefore presents a unique challenge for organizations. Despite the growing prevalence of deepfake technology, little experimental research has examined how different crisis communication strategies perform in mitigating the reputational and relational harm posed by deepfake-induced crises. Accordingly, this study seeks to (1) examine how exposure to deepfake news relates to public perceptions and affect toward …

Development And Implementation Of Educational Modules On Management Of Neonates With Critical Congenital Heart Disease In The Delivery Room (Learn-Chd)., Noorjahan Ali, Brenda Law, Alyssa R. Thomas, Philip T. Levy, Ruby Gupta, Summer Elshenawy, Danielle Reed, Leeann R. Pavlek, Jennifer Shepherd, Sharada H. Gowda, Molly K. Ball, Beth Ann Johnson, Chloe Joynt

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Neonates with congenital heart disease may require delivery room interventions beyond standard care. Because existing guidelines and educational programs rarely address these needs, we developed and evaluated targeted educational modules.

METHODS: Teams were randomized to online eLearning modules or directed readings. Individual pre-/post-knowledge scores were compared. Team performance was tested in simulated delivery scenarios including abruption, hypoplastic left heart syndrome, d-transposition of great arteries and congenital complete heart block.

RESULTS: 32 teams from 9 centers participated. The module group had improved knowledge scores (mean change 6% vs -0.3% e-Learning group, p = 0.01). Simulation performance was similar between groups …

Recreational fishing has emerged as an inclusive outdoor leisure occupation that promotes physical activity, social participation, confidence, and emotional well-being when appropriate adaptations and supports are available. The purpose of this capstone project was to develop, implement, and evaluate an adaptive fishing program for participants enrolled in the Western Michigan University Center for Disability Services (CDS) Skill Building Program. Guided by occupational therapy principles, …

July 2026 Dentistry And The Law — Can Unlicensed People Own A Dental Practice? Who Is Enforcing The Law?, Daniel Schulte Jd

The Journal of the Michigan Dental Association

This legal column addresses the complexities of dental practice ownership in Michigan, clarifying that only licensed dentists can legally own a practice through professional corporations or professional limited liability companies. It explains the "Corporate Practice of Medicine Doctrine," which aims to ensure licensed professionals, rather than profit-motivated lay persons, control health service delivery. The article details how management companies often operate legally as landlords or service providers without technically owning the practice itself. Finally, it notes that only the Michigan Department of Licensing and Regulatory Affairs and the attorney general have the authority to enforce these regulations.

Hepatitis B In The Vaccine Era: Persistent Burden And Clinical Implications, Cherechi Nwabueze, Eunice Omeludike, Ridwan Ademola Lawal, Kedife Nwabueze

School of Medicine Publications

Hepatitis B virus (HBV) infection remains a leading global cause of advanced liver disease and imposes a substantial economic burden. Early prevention is critical, as perinatally acquired HBV carries a high risk of progression to cirrhosis or hepatocellular carcinoma (HCC). Hepatitis B vaccination has been proven effective in preventing cancer, yet coverage of the complete vaccine series remains suboptimal. This implementation gap perpetuates the clinical burden, manifesting decades later as hepatic decompensation and liver cancer. This narrative review synthesizes the current HBV landscape, highlighting how gaps in vaccination policy and delivery contribute to real-world gastrointestinal outcomes. By reframing HBV vaccination …

Automated Scoring Of Prosody In Oral Reading Fluency: Integrating Acoustic And Sentence/Chunk-Level Silence Features With Machine Learning, Kuo Wang

Education Policy and Leadership Theses and Dissertations

Prosody, the ability to read with appropriate variation in pitch, duration, pausing, and stress, is an important (and challenging to measure) dimension of oral reading fluency (ORF) and comprehension. ORF prosody is currently measured through human raters and rubric-based scoring systems (e.g., the National Assessment of Educational Progress (NAEP) or the Multidimensional Fluency Scale (MDFS scales). The rating process is labor and resource-intensive and introduces rater bias. Recent work has shown acoustic features to predict prosody ratings; however, their models had low generalization performance on cross-domain data (unseen passages and student samples).

The present study investigated the automated assessment of …

Implementing suitable carbon reduction strategies requires leadership and more clarity on the practical steps that AHPs can take specific to their unique skill set. Objective: …

Discordance Between Self-Report And Performance-Based Measures Among At-Risk Older Adults: A Secondary Data Analysis, Chiung-Ju Liu, Wen-Pin Chang, Inga Wang

Occupational Therapy Faculty Publications

Importance: Subtle, age-related declines in occupational performance among at-risk older adults may go undetected when assessed solely with self-report measures, potentially leading to missed intervention opportunities. Understanding discrepancies between self-reported and performance-based occupational performance outcomes can inform assessment selection and interpretation.

Objective: To examine the discrepancies between the two types of measure among community-dwelling older adults at risk for losing independence.

Design: Cross-sectional study using secondary data analysis.

Participants: Seventy-one community-dwelling older adults (M age = 74 yr, SD = 9) who showed muscle weakness and reported difficulty with activities of daily living.

Outcomes and measures: Canadian Occupational Performance Measure …

Conflict-Mediated Group Size Regulation: A Theory Of Supraoptimal And Suboptimal Group Size, Eric Schniter

ESI Working Papers

Observed group sizes rarely match the size that would maximize what each member gets from belonging. We propose a two-part theory in which group size is regulated by two related conflicts: insider-outsider conflict over admission, and within-group conflict as crowding, competition, and social tensions intensify with size. Three strategies are available: admission, exclusion, and fission. The first part shows that even when exclusion is unavailable, fission dynamics alone drive group size away from the optimum in both directions, with the pattern set by how prospective joiners encounter groups and by the geometry of fission. When joiners compare groups across a …

In The Shadow Of The Steeple: A Theory Of Religious Hypocrisy, Justin Arthur Rice

Graduate Theses and Dissertations

In this dissertation, I explore how Christian doctrine and practice respond to the pressures placed upon them by the troubling reality of religious hypocrisy (RH). Assuming a teleological notion of social institutions, I argue that RH is best understood in relation to the Church as an institution, and that RH occurs when religious agents undermine or subvert their appointed role within the Church. RH consists in the conscious or unconscious charade of spiritual or moral virtue undertaken in one’s capacity as a member of a religious institution, grounded in a fundamental disparity between one’s thoughts, words, desires, motivations, or deeds, …

Univariate And Bivariate Binary Spatial Regression Models With Application To Plant Abundance Data, Amir Hamza Akash

Graduate Theses and Dissertations

Analyzing species distributions is of prime interest in ecological research. Prevalence of a species usually depends on several environmental and topographic features not all of which can be quantified or measured. Spatial random effects play an important role as a surrogate for missing features that can explain similarity in species prevalence patterns between neighboring locations. In this thesis, we focus on a dataset on abundance of plants in the southern part of South Africa. First, we build a hierarchical Bayesian model for binary regression, using the probit link, on presence/ absence of a species based on available covariates. Since the …

Remote Sensing-Derived Urban Heat Islands And Land Surface Phenology, Raihan Sorker

Graduate Theses and Dissertations

Thermal remote sensing has been widely applied to characterize urban heat islands (UHI) and their relationship to land use; however, few studies have explored the relationship between land surface temperature (LST) and land surface phenology (LSP). This study focused on the relationship between LST and LSP in the metropolitan region of Kansas City, Missouri, USA using Landsat 8 satellite images from 2015 to 2024. Thermal and normalized difference vegetation index (NDVI) time series were processed using Google Earth Engine to derive annual LST metrics alongside phenological indicators including timing of green-up and senescence as well as growing season length. Individually, …

Localizing And Repairing Backdoor-Sensitive Layers In Pre-Trained Language Models For Secure Fine-Tuning, Sunanda Das

Graduate Theses and Dissertations

Task-agnostic backdoor attacks can contaminate pre-trained language models (PLMs) in a way that survives downstream adaptation, even under full fine-tuning, making it difficult for practitioners to trust third-party checkpoints. Existing defenses often rely on privileged assumptions (e.g., access to poisoned data or trigger/target knowledge), thereby limiting their applicability in realistic settings. We present DiSec (Disentanglement of potentially adversarial weights for Secure fine-tuning), a robust and label-efficient purification framework that uses only clean auxiliary text and does not rely on downstream supervision or attack signatures. DiSec elicits model-internal signals from this clean data to separate suspicious parameter components that are inconsistent …

Classical Liberalism And Property, Thomas W. Merrill

Faculty Scholarship

Classical liberalism is characterized by several key attributes. Its central normative criterion is the well‑being of the individual, not some aggregate like society or the nation‑state. Individuals are presumptively regarded as responsible actors, capable of judging their own best interests and accountable for their actions that interfere with the well‑being of others. Because individuals are presumptively regarded as responsible actors, there is a strong preference for imposing only minimal obligations on them through the power of the state, and these usually involve general negative duties that are universal in character, chiefly to forbear from using force or fraud to interfere …

Presidential Immunity: Before And After Trump, Thomas P. Schmidt

Faculty Scholarship

“All the officers of government,” the Supreme Court said long ago, “from the highest to the lowest, are creatures of the law, and are bound to obey it.” Despite that ringing and categorical language, however, the Court has held that the President — the “highest” and most powerful of all government officers — is “immune” from judicial oversight in several respects. Indeed, when the Court held last Term that former presidents are presumptively immune from criminal prosecution for officials acts, the dissenters warned: “In every use of official power, the President is now a king above the law.”

There Is No Free Benchmark: An Institutional View Of Legal Ai Benchmarking, Neel Guha, Andy K. Zhang, Christine Tsang, Christopher D. Manning, Julian Nyarko, Daniel E. Ho

Faculty Scholarship

Despite substantial excitement around the use of AI in law, little information exists on the performance and associated risks of the domain’s widely marketed tools. Recent work, for instance, has demonstrated the significant potential for “hallucinations” — wherein models make up facts, law, and precedent — leading Chief Justice Roberts to spotlight this risk in his annual report on the judiciary. We argue that there is a need for public AI benchmarking in law. First, relative to other AI application domains, the legal AI ecosystem lacks legibility — there is little information about the design and performance of many commercial …

Free Expression And Civil Rights On Campus: Consistency And The Kant-Rawls Heuristic, David M. Schizer

Faculty Scholarship

Universities learned hard lessons in the months after Hamas attacked Israel on October 7. 2023. This painful and challenging time highlighted the urgent need to pursue two critical goals, which sometimes are in tension with each other. First, universities have to protect academic freedom and free expression. This is their life blood. Second, universities also have to honor their legal and moral obligation to combat discrimination, including antisemitism.

Yet this is easier said than done. Protecting free expression means allowing speech that is controversial and even offensive. But this speech can contribute to a hostile environment. So, in seeking both …

From Learner To Leader: Exploring Principals' Perspectives On Professional Learning, Development, And Mentoring, Eric William Kausch

Graduate Theses and Dissertations

This purpose of this qualitative study was to examine veteran secondary school principals’ engagement in professional learning, development, and mentoring for the improvement of their leadership skills. While previous literature provides insight into administrative preparation programs, mentoring of novice leaders, and succession planning for those advancing their careers, there are fewer studies that discuss enhancing experienced principals’ leadership development. The study was guided by three research questions: (1) How do principals describe their experiences participating in professional learning and development? (2) What types of leadership experiences do principals engage in to improve their leadership skills? and (3) How does engaging …

Investigating And Comparing Special Education Teachers’ Perceptions Of Workload Manageability And The Relationship With Attrition, Kasey Sanders

Graduate Theses and Dissertations

This study investigated special education teachers’ (SETs) perceptions of workload manageability and the relationship between these perceptions and intentions to quit. State-wide data from the Kansas State Department of Education showed a significant increase in the number of special education vacancies from a total of 161, or .03% in the 2019-2020 school year to 557, or 11%, in the 2024-2025 school year. Over the past four years, the number of special education teachers with a non-traditional license has increased from 312, or 6%, in the 2021-2022 school year to 427, or 8%, in the 2024-2025 school year (KSDE, 2025). Using …

Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger

Graduate Theses and Dissertations

This dissertation develops and tests a comparative heuristic device called optimal autonomy to explain when and how autonomous territories, or simply autonomies, become durable components of the global system of sovereign states. Drawing on a mixed‑methods case study of Denmark and the Faroe Islands, the study operationalizes optimal autonomy as a heuristic device using three interacting metrics: territorial delineation, national distinction, and state dependence. Using semi‑structured interviews with public officials and a mental‑mapping experiment with university students, this research shows that optimal autonomies are not made from single institutional designs but rather a dynamic equilibrium between maximal territorial delineation, medial …

Sigesn-Based Lasers On Silicon For Mid-Infrared Optoelectronics, Sudip Acharya

Graduate Theses and Dissertations

Germanium-tin (GeSn) alloys represent a significant advancement in semiconductor technology, particularly for applications in the short-wave and mid-infrared (SWIR and MIR) spectral ranges. As a group IV material system, these alloys offer a unique combination of tunable optoelectronic properties and full compatibility with established silicon-based manufacturing processes. The controlled incorporation of tin into germanium enables the engineering of a fundamental direct bandgap, a critical feature that distinguishes GeSn from its indirect bandgap materials, silicon and germanium. This direct bandgap behavior which was demonstrated in high-quality single crystalline GeSn alloys around the year 2015 is the foundation for efficient light emission …
