Cell Death Helps To Stabilize Populations Of Prochlorococcus, P. Wang, E. A. Laws, C. Liang, X. Liu, J. Chen, Y. Zhong, C. Li, B. Huang

Faculty Publications

Prochlorococcus is one of the dominant phytoplankton species in tropical and subtropical pelagic marine ecosystems. To maintain its population equilibrium in oligotrophic waters, the dominant species Prochlorococcus requires high loss rates to offset its high abundance and growth rates. While theoretical frameworks recognize multiple loss processes for Prochlorococcus (viral lysis, environmental stress, programmed cell death), prevailing population studies attribute main mortality to grazing. This oversight stems from in situ data gaps of non-grazing mortality processes. In this study, we firstly formulated simple differential equations that took account of population losses due to both grazing and cell death. We then used …

Coding Manual: Analyzing Semistructured Interview Data For Master Narratives, Jayson Seaman, Cindy Hartman, Andrew D. Coppens

Faculty Publications

This coding manual accompanies a methodological reorientation in narrative identity research, one that challenges the field’s prevailing “protagonist bias” — the assumption that first-person autobiographical accounts are the primary or most valid source for identifying cultural master narratives as psychological resources. While much psychological research has centered on how individuals narrate their own lives, this approach can obscure the ways that broader cultural narratives are circulated, reinforced, and contested through discourse beyond the self. This method provides researchers with a systematic approach for identifying how master narratives operate across multiple narrative levels, often outside of biographical storytelling.

Choi, Jason D. Kautz, Santiago Papini, James A. Naifeh, Pablo A. Aliaga, Paul B. Lester, Ronald C. Kessler, Robert J. Ursano, Murray B. Stein, Paul D. Biese

Faculty Publications

Background

Adverse childhood experiences (ACEs) are associated with physical and mental health difficulties in adulthood. This study examines the associations of ACEs with functional impairment and life stress among military personnel, a population disproportionately affected by ACEs. We also evaluate the extent to which the associations of ACEs with functional outcomes are mediated through internalizing and externalizing disorders.

Methods

The sample included 4,666 STARRS Longitudinal Study (STARRS-LS) participants who provided information about ACEs upon enlistment in the US Army (2011–2012). Mental disorders were assessed in wave 1 (LS1; 2016–2018), and functional impairment and life stress were evaluated in wave 2 …

Electroexcitation Of Nucleon Resonances And Emergence Of Hadron Mass, Patrick Achenbach, Daniel S. Carman, Ralf Gothe, Kyungseon Joo, Victor I. Mokeev, Craig D. Roberts

Faculty Publications

Developing an understanding of phenomena driven by the emergence of hadron mass (EHM) is one of the most challenging problems in the Standard Model. This discussion focuses on the impact of results on nucleon resonance (N*) electroexcitation amplitudes (or γ_vpN*) obtained from experiments during the 6 GeV era in Hall B at Jefferson Lab on understanding EHM. Analyzed using continuum Schwinger function methods (CSMs), these results have revealed new pathways for the elucidation of EHM. A good description of the Δ (1232) 3/2⁺, N (1440) 1/2⁺, and Δ (1600) 3/2^{+ …}

Whose Right(S)?: Civil Rights Impact Of Cultural Conflicts In The Curriculum, S. David Mitchell

Faculty Publications

Statutes seeking to prohibit the teaching of certain curricular topics that are considered divisive infringe upon the civil rights of students, parents, and teachers. The conflict over what should be taught implicates the rights of students, specifically their right to receive and to learn information; the rights of parents, specifically the right to control the education of their children; and the rights of teachers, specifically the First Amendment and academic freedom. “Anti-Woke” legislation, as it is broadly termed, is designed to silence those who seek to engage in the critical analysis of the structural and systemic barriers that have prevented …

From Disruption To Integration: Cryptocurrency Prices, Financial Fluctuations, And Macroeconomy, Zhengyang Chen

Faculty Publications

This paper examines cryptocurrency shock transmission to financial markets and the macroeconomy using a Bayesian structural VAR with Pandemic Priors from 2015 to 2024. By affecting overall risk appetite, cryptocurrency price shocks generate positive financial market spillovers, accounting for 18% of equity and 27% of commodity price fluctuations. Real economic effects are significant in driving investment but remain limited, contributing only 4% to unemployment and 6% to industrial production variance. However, cryptocurrency shocks explain 18% of price-level forecast error variance at long horizons. Narrative analysis reveals sentiment and technology as primary shock drivers. These findings demonstrate cryptocurrency's deep financial system …

Mutualistas: La Sociedad Auxiliar De Mutua Beneficiaria, Antonito Colorado, 1937-1994, José A. Rivera Ph.D

Faculty Publications

Mutual Aid Societies proliferated in the American Southwest during a period of rapid social change, 1880-1930. In Hispanic towns, these societies were referred to as mutualistas, with a large number concentrated in the San Luis Valley of Colorado and rural counties of northcentral New Mexico. One of the men’s organizations, La Sociedad Protección Mutua de Trabajadores Unidos (SPMDTU), started in Antonito, Colorado, and quickly spread to other communities of southern Colorado and northern New Mexico and eventually to a few mining towns in Utah. With a tri-state model in place, women formed their own mutual protection societies: Sociedad Protectora …

This review examines the evolution and characteristics of thirteen major CFPS reactor formats, from traditional batch systems to advanced platforms. The historical development of CFPS reactors from the 1960s to present day is presented. Additionally, for each format, operational principles, advantages, limitations, and notable applications are …

Sex-Dependent Modulation Of Behavioral Allocation Via Ventral Tegmental Area-Nucleus Accumbens Shell Circuitry, Kristen A. Mclaurin, Jessica M. Illenberger, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Diagnostic criteria for substance use disorder, cocaine type (i.e., cocaine use disorder), outlined in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders, imply that the disorder arises, at least in part, from the maladaptive allocation of behavior to drug use. To date, however, the neural circuits involved in the allocation of behavior have not been systematically evaluated. Herein, a chemogenetics approach (i.e., designer receptors exclusively activated by designer drugs (DREADDs)) was utilized in combination with a concurrent choice self-administration experimental paradigm to evaluate the role of the mesolimbic neurocircuit in the allocation of behavior. Pharmacological activation …

Faculty Publications

Objectives The benefits of physical activity (PA) and the negative impacts of sedentary time (SED) on health in youth are well established. However, uncertainty remains surrounding how PA and SED jointly influence cardiometabolic risk (CMR) factors. The aim of this study was to determine the joint influence of SED, light-, moderate- and vigorous-intensity PA (LPA, MPA and VPA), and sleep on CMR factors using five-part compositional analyses.

Methods Data were pooled from 16 cohort studies comprising 22 474 children and adolescents from the International Children’s Accelerometery Database. PA was measured using hip-mounted accelerometers with sleep self-reported. CMRs included body mass …

Symbiotic International Law: Combatting Uyghur Forced Labor, Preston Jordan Lim

Faculty Publications

Since 2017, the Chinese government has launched a campaign of repression against the Muslim Turkic minorities of Xinjiang, a region located in China’s Northwest. While most scholars have focused on the mass internment of Uyghurs and other minorities, this Article highlights an under-discussed aspect of China’s campaign: the construction of a sophisticated forced labor system. Minority forced labor supplies key sectors of the global economy—from the automotive to the energy sectors—and allows Chinese companies to outcompete foreign firms. The unprecedented scope and sophistication of what I term the “modern Xinjiang forced labor system” imperils the very future of the international …

An International Perspective On Geography Curricula: Paving A Way Forward For Geographical Thinking, Tomáš Bendl, Hilde Storrøsæter, Lene Møller Madsen, David Trokšiar, Raphaële De La Martinière, Shanshan Liu, Sizakele Serame, Jerry T. Mitchell, Péter Bagoly-Simó, Yushan Duan, Gillian Kidman

Faculty Publications

Geographical thinking is a cornerstone of modern geography education. Despite its universal value, no large-scale international study has systematically examined its integration into diverse curricular documents. This study investigates how geographical thinking is embedded in the curricula of nine countries, focusing on content and procedural dimensions. Using a structured analytical framework, the research reveals significant patterns and gaps, particularly the underrepresentation of place as a central concept, the lack of explicit focus on geographical thinking, and the limited emphasis on its procedural dimension. The findings emphasise the need for stronger interconnections between these dimensions to promote a more comprehensive approach …

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …

Climatologist Mann's Defamation Suit Victory: Can It Resolve The Crisis Of Expertise, David S. Caudill

Faculty Publications

When a jury awarded one million dollars in punitive damages to climatologist Michael Mann, in his defamation suit against writer Mark Steyn (who accused Mann of scientific fraud), it was newsworthy, even surprising, because opinions regarding scientific matters are rarely actionable. And yet it was not seen as a groundbreaking event in terms of legal doctrine, since the outcome was easily justifiable— Steyn’s accusation was provably false. However, even if the Constitutional contours of defamation law did not change, the Mann verdict has far-reaching implications for a major contemporary social phenomenon, namely the so-called crisis of expertise, a term identifying …

Stomach Content And Stable Isotope Analysis Of Invasive Lionfish (Pterois Volitans) In The Florida Keys, Emily E. Shallow, Cassandra N. Glaspie, Michael J. Polito, Mitchell S. Lovell

Faculty Publications

The invasive red lionfish, Pterois volitans, plays a unique role in seagrass and reef ecosystems, where it functions as a top predator and competitor for both food and shelter. Given the ubiquitous distribution of lionfish in the Gulf of Mexico and Caribbean basins, their species provides an excellent opportunity to understand how an invasive predator's diet and primary energy pathways change as a function of size and habitat type. To investigate these patterns, we studied lionfish from a mosaic of deep reef, shallow patch reef, and seagrass bed habitats in the Florida Keys using stomach contents and stable isotope analysis …

When Spanish officials first entered the northern region of New Spain in the late sixteenth century, they realized that irrigation would be a necessary development in the establishment of permanent communities. To sustain the early settlements, they built irrigation systems following the Iberian model, itself an extension of Arabo-Berber traditions from north Africa and the Middle East.

Unwarranted Warrants?: An Empirical Analysis Of Judicial Review In Search And Seizure, Brett James Hashimoto, Miguel F.P. De Figueiredo, Dane Thorley

Faculty Publications

Every year, police perform searches governed by the Fourth Amendment on hundreds of thousands of individuals and their property throughout the United States. Many of the academy’s most decorated scholars have focused on the genesis and jurisprudential nature of the Fourth Amendment’s warrant requirement. Surprisingly, we know almost nothing about how the Fourth Amendment regulates searches and how searches actually work in practice.

In this Article, we pull back the curtain on the search and seizure process by presenting the largest quantitative study of warrants of any kind. We analyze over 33,000 warrant applications filed through Utah’s “e-Warrants” system over …

The Risk Of Marginal Inclusion In The Fortune 500: A Quasi-Replication Of Lewis & Carlos (2023), W. Chad Carlos, Yasir Dewan, Ben W. Lewis, Brian P. Reschke, S. Isaac St. Clair

Faculty Publications

Conventional wisdom suggests that being included in an exclusive ranking leads to positive external evaluations. However, Lewis and Carlos (2023) found that firms situated near the threshold for inclusion on the 100 Best Corporate Citizen ranking were devalued by investors. To assess the generalizability of this surprising finding, we quasi-replicate and extend this finding by applying the same regression discontinuity design to the Fortune 500 ranking. We find corroborating evidence: firms near the bottom of the Fortune 500 receive lower external evaluations, not only from investors but also from industry peers. Our findings therefore quasi-replicate and extend Lewis and Carlos’ …

Six Paths Of Global China: A Genealogy Of A Contested Geographical Imaginary, Jessica Dicarlo, Meredith J. Deboom

Faculty Publications

‘Global China’ has emerged as a shorthand for China's relationship to the global, but its axiomatic uses disguise considerable complexity. This article troubles self-evident uses and tidy categorizations of Global China by approaching it as an emergent, pluralistic geographical imaginary warranting critical analysis. Employing a genealogical approach that privileges indeterminacy and inconsistency over linearity and singularity, we draw on wide-ranging sources to reveal the contested, contextual, and contradictory uses of Global China in the contemporary moment. Our analysis identifies six ‘paths’ of Global China: Other, Integration, Bridge, Status, Threat, and Alternative. Each path facilitates distinct yet interlinked claims about …
