Reassessing Policy Responses To Irregular Migration In Receiving Democracies: A Process-Tracing Analysis Of Transactional Migration Governance, Otoniel Ramos

Student Research

This policy brief analyzes the growing use of transactional migration agreements (TMAs) by receiving democracies—bilateral arrangements that exchange financial or diplomatic concessions for the external enforcement of migration control. While politically expedient, TMAs often generate long-term strategic liabilities: they reduce state control over enforcement outcomes, expose receiving states to coercive leverage by partner states, and weaken normative commitments to transparency and rights protection. Using analytic process tracing and formal modeling, this paper identifies four recurring mechanisms by which TMAs evolve into systems of asymmetric dependence. It then evaluates three alternative policy frameworks—Exit Doctrine, Legal Category Reform, and a Structured Conditionality …

Leveraging Reduced Order Models And High-Fidelity Simulations For Efficient Multifidelity Uncertainty Quantification Of Thermal Systems, Jakob G. Bates

Theses and Dissertations

Simulation-led design is becoming an important part of thermal systems design. Simulations of thermal systems continue to improve in their fidelity, but this comes with an increased computational cost. Additionally, uncertainty in simulation inputs, such as thermophysical properties, leads to uncertainty in simulation outputs. For simulations to be used rigorously for simulation-led design, this uncertainty must be quantified. Performing uncertainty quantification on thermal simulations is made difficult by their many uncertain parameters and high computational cost. Multifidelity uncertainty quantification is a set of methods that reduce the cost of uncertainty quantification by leveraging high-fidelity, high-cost simulations with low-fidelity, low-cost simulations. …

Woodchip-Based Permeable Reactive Barriers For Groundwater Nitrogen Removal: Design Optimization To Minimize Greenhouse Gas Release Informed By Experimental Studies And Reaction-Transport Modeling, Jing-An Lin Phd

Electronic Dissertations and Theses, 2010-current

Submarine groundwater discharge of legacy nitrogen can significantly contribute to coastal eutrophication. Permeable reactive barriers (PRBs) that intercept contaminated groundwater and provide a carbon source for microbially mediated denitrification are increasingly considered to remove nitrate before it reaches coastal surface waters. While woodchips have been shown to efficiently remove nitrate, open questions remain regarding the nitrogen removal performance of PRBs with different woodchip arrangements (trench-type vs column arrays), woodchip types (hardwoods vs softwoods) and the potential formation, release and fate of secondary byproducts, specifically greenhouse gases and dissolved iron. This dissertation aimed to address these knowledge gaps through a combination …

The Influence Of Extrusion Geometry And Ratio On Extrudate Mechanical Properties For A 6005a Alloy Containing Either Sc And Zr Or Cr And Mn Dispersoid Formers, Eli A. Harma, Paul Sanders, Thomas Wood, Timothy Langan

Michigan Tech Publications

There is a demand for a 6005A series extrusion alloy with improved strength that maintains good extrudability. Replacing Mn and Cr dispersoid formers with Sc and Zr is expected to increase the room temperature mechanical properties while not affecting extrudability. Al3X dispersoids with a Sc core surrounded by a Zr shell are stable at higher temperatures and enhance recrystallization resistance and precipitation strengthening. However, there is little information on how the Sc and Zr additions affect the properties of an extrudate as a function of extrusion geometry and ratio. A 6005A series alloy with Cr and Mn additions is compared …

Antifreezing Hydrogels From Mechanisms, Strategies, To Applications, Jie Zheng, Dong Zhang, Hong Cheng, Yanxian Zhang

University Research

Antifreezing hydrogels have emerged as an innovative solution for maintaining functional performance and mechanical integrity in subzero environments, offering a robust alternative to traditional water-free antifreezing materials that often fail under wet and cold conditions. These water-rich hydrogels leverage their porous, crosslinked, polymeric networks, which serve as the structural basis for implementing two parallel strategies: the incorporation of antifreezing additives (peptides/proteins, salts, ionic liquids, and organics) and the meticulous engineering of polymer systems and network structures for manipulating the water–ice phase equilibrium to significantly enhance antifreezing properties. This review synthesizes recent findings to provide a fundamental overview of the important …

Thermaltrack Dataset - Training Labels - Sequence 1-11, Yiming Yang, Jeremy P. Bos

ThermalTrack

We present a wheel track detection system that leverages RGB-Thermal (RGB-T) imaging, where thermal channels reveal critical temperature differentials between compacted tracks and loose snow - tracks exhibit higher thermal inertia and lower reflectivity, emitting stronger radiation signatures even in visually homogeneous conditions. By fusing these distinctive thermal patterns with RGB spatial information, our method reliably identifies navigable tracks, enabling robust path-following in complete white-out conditions where snow textures and terrain features become indistinguishable.

Employee Engagement Within The E-Commerce Industry, Kwami Seyram Dzahini

Walden Dissertations and Doctoral Studies

Employee engagement poses a significant challenge for human resources (HR) managers in the e-commerce industry. Employees experiencing engagement issues may demonstrate lower commitment and heightened workplace incivility, ultimately affecting business profitability. Grounded in the employee engagement theory, the purpose of this quantitative correlational study was to examine the relationship between work-life balance, professional growth, and employee engagement initiatives within U.S. e-commerce companies. The study involved 72 HR managers and full-time employees from the Eastern U.S. region, who participated in an online survey. Data were analyzed using multiple linear regression. The results were statistically significant, F(2, 69) = 12.475, p < .001, R² = .266, indicating that the model accounted for 26.6% of the variance in employee engagement. Professional growth emerged as a significant predictor of employee engagement, t = 2.62, p = .011, ß = 0.36. A key recommendation for e-commerce HR managers is to monitor engagement levels through surveys, feedback sessions, and performance indicators. Analyzing trends in employee retention, absenteeism, and productivity can allow leadership to make data-driven decisions and adjust strategies as needed. The implications for positive social change include the potential for HR leaders to enhance the value and satisfaction of employees, improve retention, and foster a more productive workforce that contributes positively to the overall health of the e-commerce industry and broader economy.
