Understanding the diversity-productivity relationship (DPR) is crucial for elucidating the ecological functions of marine bacterioplankton. However, studies have often focused on species diversity, neglecting phylogenetic diversity, which may offer deeper insights into the complex ecological processes shaping DPR in natural systems. This study addressed this gap by exploring the role of phylogenetic diversity in bacterioplankton productivity in the northern South China Sea, a coastal ecosystem influenced by estuarine plumes. We aimed to disentangle the mechanisms driving DPR and investigate how estuarine plumes modulate these processes. Our results show that the substantial enhancement of phytoplankton production by the Pearl River plume …


Playing Politics With Traffic Fines: Sheriff Elections And Political Cycles In Traffic Fines Revenue, Min Su, Christian Buerger Jan 2025

Playing Politics With Traffic Fines: Sheriff Elections And Political Cycles In Traffic Fines Revenue, Min Su, Christian Buerger

Faculty Publications

The political budget cycle theory has extensively documented how politicians manipulate policies during election years to gain an electoral advantage. This paper focuses on county sheriffs, crucial but often neglected local officials, and investigates their opportunistic political behavior during elections. Using a panel data set covering 57 California county governments over four election cycles, we find compelling evidence of traffic enforcement policy manipulation by county sheriffs during election years. Specifically, a county's per capita traffic fines revenue is 9% lower in the election than in nonelection years. The magnitude of the political cycle intensifies when an election is competitive. Our …


Do Major Customers Affect Firms' Environmental, Social And Governance Activities?, Feng Dong, John A. Doukas, Stephanie Walton, Rongyao Gloria Zhang, Yiyang Zhang Jan 2025

Do Major Customers Affect Firms' Environmental, Social And Governance Activities?, Feng Dong, John A. Doukas, Stephanie Walton, Rongyao Gloria Zhang, Yiyang Zhang

Faculty Publications

We examine the role of major customers in shaping firms' environmental, social and governance (ESG) practices. We find that firms with major customer relationships undertake fewer ESG activities compared to those without such ties. The association is attenuated when institutional ownership is high, firms are less diversified, customers exhibit greater bankruptcy risk and lower switching costs and during periods of elevated equity market sentiment. Taken together, our findings highlight that reliance on a concentrated customer base can weaken firms’ incentives to engage in ESG practices, with important implications for supply chain sustainability.


Rethinking The Lake History Of Taylor Valley, Antarctica During The Ross Sea I Glaciation, Michael S. Stone, Peter T. Doran, Krista F. Myers Jan 2025

Rethinking The Lake History Of Taylor Valley, Antarctica During The Ross Sea I Glaciation, Michael S. Stone, Peter T. Doran, Krista F. Myers

Faculty Publications

The Ross Sea I glaciation, marked by the northward advance of the Ross Ice Sheet (RIS) in the Ross Sea, east Antarctica, corresponds with the last major expansion of the West Antarctic Ice Sheet during the last glacial period. During its advance, the RIS was grounded along the southern Victoria Land coast, completely blocking the mouths of several of the McMurdo Dry Valleys (MDVs). Several authors have proposed that very large paleolakes, proglacial to the RIS, existed in many of the MDVs. Studies of these large paleolakes have been key in the interpretation of the regional landscape, climate, hydrology, and …


The Work Of An Hour: A Case Study Of Propaganda, Michael F. Russo Jan 2025

The Work Of An Hour: A Case Study Of Propaganda, Michael F. Russo

Faculty Publications

This research paper discusses the messaging of United States President George W. Bush and his administration regarding the U.S. led invasion of Iraq. Transcripts of presidential communications, national news programs, and public opinion polls from 2001-03 were analyzed to identify patterns in these communications. This review demonstrated techniques similar to those used in historical propaganda campaigns to sway public opinion. The introduction and repetition of key terminology from the government was followed by magnification by television news programs. These messages were broadcast despite lack of evidence of Iraq’s involvement with the 9/11 attacks or their possession of weapons of mass …

Bridging the gap between carbon storage theory and petroleum engineering practice.

This comprehensive guide distills nearly two decades of research and teaching into a clear, application-focused resource on geological CO2 storage modeling, carbon capture and storage modeling (CCS modeling), and CO2 reservoir modeling—all tailored specifically for petroleum engineers.

While GCS modeling has historically been driven by physics, mathematics, and hydrogeology, petroleum engineering CO2 modeling often requires a different approach. This book translates complex, multidisciplinary CO2 geological modeling techniques into a unified, petroleum engineer–friendly framework. Whether your focus is CO2 sequestration engineering, enhanced oil recovery CO2 modeling, or transitioning from oil …


All-Electron Molecular Tunnel Ionization Based On The Weak-Field Asymptotic Theory In The Integral Representation, Imam S. Wahyutama, Denawakage D. Jayasinghe, François Mauger, Kenneth Lopata, Kenneth J. Schafer Jan 2025

All-Electron Molecular Tunnel Ionization Based On The Weak-Field Asymptotic Theory In The Integral Representation, Imam S. Wahyutama, Denawakage D. Jayasinghe, François Mauger, Kenneth Lopata, Kenneth J. Schafer

Faculty Publications

Tunnel ionization (TI) underlies many important ultrafast processes, such as high-harmonic generation and strong-field ionization. Among the existing theories for TI, many-electron weak-field asymptotic theory (ME-WFAT) is by design capable of accurately treating many-electron effects in TI. An earlier version of ME-WFAT relied on an accurate representation of the asymptotic tail of the orbitals, which hindered its implementation in Gaussian-basis-set-based quantum chemistry programs. In this work, we reformulate ME-WFAT in the integral representation, which makes the quality of the asymptotic tail much less critical, hence greatly facilitating its implementation in standard quantum chemistry packages. The integral reformulation introduced here is …

Export Diversification And Economic Growth In Sub-Saharan Africa: Could There Be A Mixed Relationship?, Jocelyne Urielle Bedime, Julien Brice Minkande, Honoré Bidiasse Jan 2025

Export Diversification And Economic Growth In Sub-Saharan Africa: Could There Be A Mixed Relationship?, Jocelyne Urielle Bedime, Julien Brice Minkande, Honoré Bidiasse

Journal of African Trade

Based on the differences in export diversification between sub-regions, this research aims to determine the type of relationship that may exist between export diversification and economic growth in Sub-Saharan Africa. Using data from 36 countries grouped according to their level of diversification, a panel ARDL model is estimated. The results show that for highly diversified sub-regions, the relationship between export diversification and economic growth is inverted U-shaped, while for concentrated sub-regions, the relationship is U-shaped. Highly diversified countries are advised to integrate further into the African continental free-trade zone, which, by lifting barriers and improving the regulatory framework, offers greater …


Exploring The Role Of Online Discussion Forums In Endorsing Egyptian Undergraduates’ Efl Learning, Wesam Khairy Morsi Jan 2025

Exploring The Role Of Online Discussion Forums In Endorsing Egyptian Undergraduates’ Efl Learning, Wesam Khairy Morsi

English Language and Literature

eLearning Management systems (eLMS) are software applications used in universities worldwide to implement specific educational goals. eLearning platforms have several features that support traditional Face to Face (FTF) teaching and provide valuable opportunities for independent, self-paced learning. One of these features is the Online Discussion Forums (ODFs). This research paper investigates the role of ODFs in endorsing English as a Foreign Language (EFL) learning by examining students' perceptions of its accessibility, peer/instructor interaction, assessment criteria, and discussion topics. The paper also investigates the influence of gender on students' perceptions of the role of ODFs. This is a non-experimental research design, …

Childhood Adversity, Stress Management, And Reactions To Sensitive Content: A Latent Profile Analysis Of Undergraduates, Jessica D. Cless, Carol A. Johnston, Briana S. Nelson Goff, Olivia K. Edwards

Human Development and Family Science Faculty Publications

Current rates of adverse childhood experiences (ACEs) in undergraduate students point to a need for evaluating the impact of these events on student well-being, particularly in the context of courses that contain sensitive and trauma-based content. The current latent profile analysis study included 94 students and sought to identify patterns of exposure to adversity, stress management, and self-reported experiences in a trauma-based undergraduate course. Profile results indicated three distinct groups, interpreted as low-ACE exposure, moderate-ACE exposure, and high-ACE exposure. Student perceptions of sensitive course content were generally favorable across groups, suggesting that despite varying levels of prior adversity and stress …


Hope For Louisiana’S Coast: From Catastrophic Loss To Transient Gain, Richard Condrey, Brian D. Marx, Frank Saforo, Rudy Bartels Jan 2025

Hope For Louisiana’S Coast: From Catastrophic Loss To Transient Gain, Richard Condrey, Brian D. Marx, Frank Saforo, Rudy Bartels

Faculty Publications

Louisiana’s fifty-billion-dollar coastal restoration plan relies on selected interpretations of a small dataset of coastwide land measurements. In the 1990’s, the plan’s founders used a mathematically impossible interpretation of an improbable manipulation of the initial (1932-1990) dataset to justify their misconceptions regarding natural conditions; delta-switching; and a failing, 60-year restoration goal. In 2017, the dataset was updated to 2016 and used to suggest that land loss had slowed to -28 km2/yr (-1 football field/100 min) since 2010. We find that the dataset does not support this suggestion. Rather, we find the dataset supports our hypothesis that increasing precipitation in the …

Review Of Digging For The Disappeared: Forensic Science After Atrocity, Abigail Vaughn

Nebraska Anthropologist

Since the field's development, individuals and communities involved in and affected by international forensic investigations have been confronted with many political and ethical dilemmas. The book, Digging for the Disappeared: Forensic Science After Atrocity (2015), by Adam Rosenblatt, attempts to identify and articulate the various debates surrounding humanitarian forensic work. In doing so, the author focuses on four key areas; the purpose of such investigations, the stakeholders and expectations involved, and what may realistically be accomplished. While sympathetic to the perspective of forensic practitioners, Rosenblatt presents the positions of all parties in an unbiased manner, introducing the reader to …


Lost Fatherhood: Including Fathers In The Post-Dobbs Abortion Debate, Linda L. Schlueter Jan 2025

Lost Fatherhood: Including Fathers In The Post-Dobbs Abortion Debate, Linda L. Schlueter

Faculty Articles

Scientific studies over the last five decades show the negative impact an abortion can have on the men who fathered the aborted children. These studies demonstrate that those men-even if they supported the woman's decision to have an abortion-can experience a variety of psychological problems including depression, anger, hopelessness, helplessness, broken or damaged relationships, feelings of emasculation, and loneliness. Despite these compelling studies, little or no real attention is given to involving men in the legal debate regarding abortion. The abortion debate presents a legal Rubik's Cube of thorny issues that can affect the mother, the father, and the unborn …
