Globalization And Structural Transformation: The Role Of Tradable Services, Sang Min Lee

Faculty Publications

This paper studies how globalization impacts structural transformation from goods to services. I construct a multi-country, multi-sector model in which the transformation occurs through changes in income, prices, comparative advantage, or input-output linkages. I parameterize it with data from 1995 to 2018 for 66 countries covering diverse stages of economic development. Decomposition exercises show that globalization outweighs productivity growth in shaping structural transformation and that globalization’s impact primarily operates through comparative advantage. Counterfactual exercises reveal globalization’s heterogeneous impact on countries’ structural transformation. I characterize the underlying factor behind this result: Globalization affected countries’ transformation to the extent that it altered …

Complex Spin Structure In Co-Trimer-Chain Li2Co3Se4O12, Jie Xing, Feng Ye, Daniel Duong, Sai Mu, Max T. Pan, Rongying Jin

Faculty Publications

Complex magnetic materials are extremely attractive for revealing unconventional spin states and novel magnetic excitations. Here, we report the structural, thermodynamic, and magnetic properties of a novel magnetic material Li₂Co₃Se₄O₁₂based on x-ray and neutron diffraction, specific heat, magnetization, and x-ray photoelectron spectroscopy measurements. X-ray and neutron diffraction refinements reveal two Co sites Co (1) and Co (2) even though both are in the octahedral environment. While they are not connected along the b and c directions, these octahedra are edge-shared forming the Co (2) – Co (1) – Co (2) trimer chain …

Ecology And Life History Of Baleen Whales Inform Climate Change Vulnerabilities And Priorities For Future Monitoring, Lesley H. Thorne, Erin L. Meyer-Gutbrod

Faculty Publications

Baleen whales are key consumers in marine habitats that serve as vectors of nutrients, but their populations have been slow to recover from past commercial whaling due to their low reproductive rates and ongoing anthropogenic threats. Climate impacts have become central to the demography and habitat use of baleen whales, and conservation efforts must account for these impacts to be effective. However, knowledge of baleen whale climate responses is lacking, and current survey effort is insufficient to capture changes in migration and habitat use for many species. Due to their unique combination of ecological and life history characteristics, baleen whales …

Contraceptive Autonomy Of Adolescents And Young Adults In The U.S. South: The Influence Of Healthcare Providers, Partners, And Parents, Kathleen Broussard, Laura D. Lindberg, Emily S. Mann

Faculty Publications

A growing body of research describes coercive experiences in contraceptive care in the clinic setting, a phenomenon that disproportionately constrains the contraceptive autonomy of women who are young, low-income, Black, or Latinx. Less research has examined how other social influences may constrain contraceptive use and decision-making. We examine contraceptive autonomy across three domains of interpersonal influence (healthcare providers, sexual partners, and parents) and by race (Black vs. White). Between July–September 2023, we surveyed 1207 Black and White adolescents and young adults (AYAs) assigned female at birth living in five southern states. Over half of all respondents reported feeling social pressure …

Algorithm-Based Pay-For-Performance (Apfp) Systems: Paradoxes In Artificial Intelligence's Influence On Pay-For-Performance Theories, Anthony Nyberg, Dhuha Abdulsalam, Ormonde Cragun, Vijayesvaran Arumugam

Faculty Publications

Although artificial intelligence (AI) and generative AI (GenAI) are increasingly used to assess and reward employees, their implications for foundational pay-for-performance (PFP) theories remain underexplored. Traditional PFP systems are effective in an era of static evaluations and infrequent feedback, but they lack the intelligence and flexibility needed for today's dynamic work environments. In response, we introduce algorithm-based PFP (APFP) systems—PFP systems that leverage AI and GenAI to enable real-time adaptability, predictive capabilities, customization, automated algorithmic recommending, and measurement sophistication. We then use the APFP framework to assess its implications for three foundational PFP theories (equity theory, expectancy theory, and tournament …

Demography And Dispersal Influence The Relationship Between Habitat Suitability And Population Density, Cleber Ten Caten, Tad Dallas

Faculty Publications

A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested that local dynamics affect the relationship between habitat suitability and density. We simulated population dynamics for 200 virtual species considering different combinations of factors (demographic stochasticity, dispersal, and intraspecific competition) that affect population sizes and SDMs were trained using different sets of environmental predictors to evaluate when …

Bridging 2d And 3d Computational Modeling Of Vacuum Arc Remelting: Capturing Rotating Arc Dynamics In Axisymmetric Simulations, Zilong Zhang, Elaheh Dorari, Ramesh Minisandram, Shakarjee Krishnamoorthi, Lang Yuan

Faculty Publications

Computational modeling of the Vacuum Arc Remelting (VAR) process has been developed to provide a deeper physical and metallurgical understanding and assist in the manufacture of defect-free ingots. While fully 3D, time-resolved arc models capture arc–melt interactions with high fidelity, their high computational cost makes 2D steady arc models still the preferred option in industrial applications. In this study, a multi-physics VAR model, which accounts for magnetohydrodynamics, heat transfer, fluid dynamics, and melting/solidification, was established in ANSYS Fluent for Alloy 718 in 3D with a rotating arc. It was validated against measured melt pool morphology. A new 2D axisymmetric oscillating …

Faculty Publications

Background:

The treatment and prognosis of melanoma have historically been based on histologic stage and Breslow depth; however, due to the increase in surveillance, melanomas are being identified at an earlier stage and lower Breslow depth. Advances in genetic testing, such as Decision Dx®, mean that melanoma diagnostic decisions and prognosis can now be directed by genetics. The purpose of this project was to assess the influence of a Decision Dx® high-grade (Class 2A/B) classification on the treatment of melanoma patients at a regional medical center, particularly those not deemed high risk by conventional classification methods, including Breslow depth and …

Levers Of Default: Can The President Unilaterally Alter The Terms Of The National Debt?, Lev E. Breydo, Nathan B. Oman

Faculty Publications

The inviolability of America’s $30 trillion debt is a cornerstone of global markets and the U.S. economy. This Essay identifies a critical loophole: the President’s underappreciated power to dramatically change its legal structure—and argues that Congress should act to prevent a potential catastrophe.

The Essay details, for the first time in the literature, the arcane legal architecture underpinning America’s sovereign borrowings. Our analysis finds that although the President lacks authority to change the terms of outstanding debt retroactively, the President can accomplish similar goals by issuing new debt instruments that embed unprecedented powers. In surprisingly short order, a determined Executive …

Using The Misinformation Exposure-Trust Framework For Audience Segmentation: Predicting Covid-19 Vaccine Hesitancy Among U.S., Jing Zeng, Jinxu Li, Nan Yu, Xi Cui, Anli Xiao Ph.D.

Faculty Publications

This study examines whether individuals’ exposure to and trust in COVID-19 vaccine misinformation can be used to segment audiences and explain variations in vaccine hesitancy and health beliefs. Using k-means clustering, a survey of 819 U.S. college students (March–May 2021) identifies four subgroups based on combinations of high or low misinformation exposure and trust: misinformation-shielded (low exposure, low trust), misinformation-vulnerable (low exposure, high trust), misinformation-resistant (high exposure, low trust), and misinformation-accepting (high exposure, high trust). These subgroups differ significantly in political ideology, vaccine hesitancy, and health beliefs. The misinformation-shielded subgroup reports more liberal views, lower hesitancy, and higher perceived efficacy, …

Exosome Engineering For Blocking Gut Dysbiosis And Inducing Cell Death Mechanisms In Glioblastoma Multiforme, Ahalya Muraleedharan, Karthik Rangavajhula, Swapan K. Ray

Faculty Publications

Glioblastoma multiforme (GBM) is the most lethal primary brain tumor in adults. Emerging evidence endorses that gut dysbiosis contributes to GBM progression through the gut–brain axis (GBA), promoting inflammation and therapeutic resistance via abnormal short-chain fatty acid production and cytokine dysregulation. Exosomes, naturally occurring nanovesicles (30–150 nm), offer promising therapeutic potential due to their blood–brain barrier permeability, biocompatibility, and versatile cargo capacity. This review examines exosome engineering strategies for dual targeting: inhibiting alterations in gut microbiome and inducing regulated cell death mechanisms such as apoptosis and ferroptosis in GBM. We describe exosome engineering with detailed focus on cargo loading approaches …

Paternal Effects Without Paternity? Testing Non-Genetic Male Influence On Offspring Size And Brood Size In A Gynogenetic Vertebrate, The Amazon Molly (Poecilia Formosa), Ulrike Scherer, Sean Ehlman, David Bierbach, Jens Krause, Max Wolf

Faculty Publications

Paternal effects, i.e., effects of fathers on the phenotype of their offspring that are not mediated by the transmission of alleles, are increasingly recognized as a potentially significant source of phenotypic variation across taxa – even in the absence of paternal care. Gynogenetic systems, which rely on sperm to trigger embryogenesis without incorporating male genetic material, provide a powerful way to experimentally isolate paternal effects from effects caused by the integration of male genetic material. Up to now, however, paternal effects remain largely unexplored in these systems. Here, we tested for non-genetic paternal effects in the gynogenetic Amazon molly ( …

Vibrations from experimental setups and the environment are a persistent source of noise for low-temperature calorimeters searching for rare events, including neutrinoless double beta (0νββ) decay or dark matter interactions. Such noise can significantly limit experimental sensitivity to the physics case under investigation. Here, we report the detection of marine microseismic vibrations using mK-scale calorimeters. This study employs a multi-device analysis correlating data from CUORE, the leading experiment in the search for 0νββ decay with mK-scale calorimeters, and the Copernicus Earth Observation program, revealing the seasonal impact of Mediterranean Sea activity on CUORE’s …

Rapid Single-Cell Measurement Of Transient Transmembrane Water Flow Under Osmotic Gradient, Hong Jiang, Jinnawat Jongkhumkrong, Y. J. Chao, Qian Wang, Guiren Wang

Faculty Publications

Aquaporins (AQPs) are critical for transmembrane water transport in response to osmotic gradients, but their gating and regulatory mechanisms remain poorly understood. A central challenge is the lack of methods to measure water flow across AQPs from individual cells with the spatiotemporal resolution and sensitivity equivalent to patch-clamp recordings of ion fluxes—a limitation stemming from the electrically silent nature of water flow. Here, we present a novel optical technique—Flow-Induced Fluorescence Increase Velocimetry (FIFIV) based on Laser-Induced Fluorescence Photobleaching Anemometry (LIFPA)—that enables direct, real-time monitoring of cytoplasmic flow induced by transmembrane water transport under osmotic pressure gradients. Using small molecular fluorescent …
