Dental implant placement in the posterior mandible can be impacted by the presence of the lingual concavity. Perforating the lingual cortical bone could lead to life-threatening hemorrhage/airway obstruction. The aim of this retrospective study is to examine dentate and partially edentulous mandibles to describe anatomical variations related to the lingual concavity by evaluating cone beam computed tomography (CBCT).

Staff Matters: Adding Background Checks And Drug Testing To The Hiring Process, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This article advises dental practices on legally and carefully implementing pre-employment background checks and drug testing. It emphasizes ensuring non-discriminatory practices by consistently applying policies and clearly defining screening criteria. Practices must obtain written applicant authorization and provide notification of Fair Credit Reporting Act (FCRA) rights before conducting checks. When evaluating results, relevance to the job and timing of convictions should be considered, avoiding blanket bans. For drug testing, transparency is key. Given Michigan's recreational marijuana legality, a positive THC test does not automatically indicate impairment, requiring practices to define their approach. Using a reputable third-party provider for both screenings …

Regulatory Tension In Highly Structured Organizations, David Elliott Sr.

All Dissertations

This study examines the psychological mechanisms by which employees with a pronounced propensity for risk-taking navigate highly formalized organizational environments. Utilizing a longitudinal, three-wave cross-sectional design with temporal separation, the research surveyed 220 employees with psychometrically validated instruments to assess personality traits, role conflict, and organizational identification. Anchored in an integrative framework that combines regulatory focus theory (Higgins, 1997) and identity theory (Burke & Stets, 2009), the study hypothesized that self-verification striving and a growth mindset mediate the relationships between risk-seeking tendencies and the outcomes of role conflict and organizational identification, with organizational structure serving as a moderating variable. Structural …

12co Ro-Vibrational Spectroscopy Of Protoplanetary Disks: Inferring Planet-Disk Interactions, Janus Kozdon

All Dissertations

Observing and studying planets around young stars during their initial formation stages is essential for understanding the physics of their formation. Protoplanetary disks are the host sites of planets, and they exhibit substructures that hint towards the planets' presence, but the planet itself has rarely been detected. Analysis of the substructures in protoplanetary disks, especially towards the inner regions where most planets seem to lie, will provide information that can be used to refine theories about planet-disk interactions and, ultimately, planet formation. To probe the high-velocity inner regions, this study utilizes high-resolution spectroscopy, which has increased sensitivity with increasing velocities. …

Data-Driven Stochastic Programming For Disaster Housing Logistics Planning, Sheng-Yin Chen

All Dissertations

This dissertation develops an integrated modeling and solution framework for direct temporary disaster housing logistics under demand uncertainty. The proposed framework addresses the problem from short-term, long-term, and computational perspectives. First, a two-stage chance-constrained stochastic programming (TSCC) model is developed for short-term housing logistic planning, with demand scenarios generated via a data-driven spatial regression model that captures the relationship between housing demand, hazard exposure, and socioeconomic factors. A case study based on Hurricane Ian demonstrates that the TSCC model outperforms deterministic and traditional scenario-based models in both solution quality and robustness. Second, to address long-term housing logistics planning, a multi-horizon …

Crevice Corrosion Mechanisms Of Cocrmo Alloys In Orthopedic Implants: Retrieval Analysis, Nano-Tribocorrosion And Cellular Responses, Hwaran Lee

All Dissertations

Mechanically assisted corrosion and non-mechanically (chemically) driven corrosion in modular junctions of orthopedic implants using cobalt-chromium-molybdenum (CoCrMo) alloys remain clinical concerns and may contribute to implant failure. The underlying corrosion mechanisms are not yet fully understood, leaving a critical research gap. We hypothesized that corrosion in modular junctions may be driven by aggressive local environments, including fretting, metal ion release (cobalt ion, Co²⁺), low pH and reactive oxygen species (ROS). This dissertation aims to (1) analyze corrosion modes and potential causes in modular junctions; (2) identify chemically driven corrosion modes on CoCrMo alloys using simulated inflammatory modular taper …

Constructing A State: Canals And The Transformation Of The Economy, Politics, And Finance In Nineteenth-Century New York, Youwei Xing

All Dissertations

This dissertation consists of three essays in economic history, unified by a focus on one of America's earliest transportation infrastructures, the canal system, in nineteenth-century New York. Each chapter explores a different aspect of the state's transformation: its economy, politics, and finance, each of which helped construct New York as the Empire State.

The first chapter studies the economic impact of canals on economic modernization from three aspects: sectoral transition, urbanization, and banking development. Contrary to much of the modern literature finds transportation infrastructure leads to decentralization, I find the opposite-evidence of centralization. Specially: (1) canal towns experienced a transition …

Three Essays On Mental Health Courts, Taylor E. Le Moal

All Dissertations

Mental illness in the criminal justice system is a major issue, with 2 in 5 incarcerated people in the US having a serious mental illness (Criminalization of People with Mental Illness, n.d.). Prisons have turned into “de facto” mental health facilities when these facilities are not equipped to do so. This means once individuals are released from incarceration, they are often ill-equipped to return to regular life and may get caught up in the cycle of recidivism (Slate, 2017). One method that policymakers have used to solve this problem is mental health courts (MHCs), which are pre-trial diversion …

Despite its advantages, conventional P(VDF-TrFE)-based devices often require external poling and face limitations in integration with low-cost, flexible substrates. To overcome these limitations, this research study explores the nanofiller approach, along with facile fabrication processes, and structural design strategies aimed at …

Gender And Entrepreneurial Success: Examining The Relationships Among Risk Aversion, Loss Aversion, Risk Propensity, And Venture Performance, Kara Mcalister

All Dissertations

Gender disparities in entrepreneurship persist despite increased participation by women entrepreneurs. Traditional research has attributed these disparities to gender differences in risk-taking behavior, with women entrepreneurs typically characterized as more risk-averse. However, recent evidence suggests this oversimplifies a complex phenomenon and may reinforce harmful stereotypes. This study examined the relationships among risk aversion, loss aversion, risk propensity, and venture performance for male and female entrepreneurs, while considering moderating effects of industry gender-type and previous experience.

A quantitative cross-sectional design was employed with 157 entrepreneurs (93 female, 64 male) recruited from entrepreneurial organizations. Risk aversion was measured using the Domain-Specific Risk-Taking …

Understanding The Experiences Of White Female Elementary School Teachers Who Promote Racial Equity And Justice In White Schools, Meredith Valentine

Theses, Dissertations and Culminating Projects

In this qualitative study, I conducted semi-structured interviews of six white, female elementary school teachers to better understand how and why they enacted principles of racial equity to challenge the status quo of whiteness with their predominantly white middle-class students and school community. Teachers felt they lacked a formal, structured education to feel confident in their teaching of racial and social justice concepts. Teachers used other forms of social justice teaching that they were more experientially familiar with, such as gender equity, language diversity, and (dis)ability, as a catalyst to discuss topics of racial justice. Each educator navigated their classroom …

How Developers Use Type-System Related Programming Language Features, Samuel W. Flint

School of Computing: Dissertations, Theses, and Student Research

Optional type annotations are a popular feature of programming languages that allow developers to omit explicit type information in code while, in some cases, retaining many of the benefits of static typing, such as in-code documentation, improved detection of type errors, or enforcement of code properties. However, how developers use and understand optional type annotations is not clear. The focus of this dissertation is to understand the use and comprehension of optional type annotations.

Optional type annotations are examined through four lenses: first, by examining the evolution of usage in a statically typed programming language (Kotlin, the default language for …
