A Review Of Flood Mitigation Benefit-Cost Analyses’ Inclusiveness Of Environmental Watershed Effects And Environmental Vulnerability: Gaps In Progress Towards More Resilient Flood Hazard Decision-Making, Fahmida Akhter, Sapana Bastola, Jerrod Penn, Thomas Douthat

Faculty Publications

US and EU flood mitigation policy both incorporate considerations of costs and benefits, and in recent years have taken steps to encourage accounting for positive and negative effects on vulnerable populations, broader non-market environmental impacts, and downstream effects beyond the target area of projects of flood mitigation projects. This work highlights the extent to which previous academic flood mitigation Benefit-Cost Analyses (BCA) papers have comprehensively considered such project effects. We do so through a systematic, PRISMA-style, review of BCA literature in the broader field of flood hazard mitigation and resilience decision-making. Our results suggest 1) most projects focus on monetizing …

Coupling Between Bacterial Phylogenetic Diversity And Heterotrophic Productivity In A Coastal Ecosystem Affected By Estuarine Plumes, Yao Liu, Shujie Cai, Wenxin Fan, Wupeng Xiao, Xin Liu, Edward A. Laws, Bangqin Huang

Faculty Publications

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 …

A Systematic Review Of Environmentally Persistent Free Radical (Epfr) Formation, Characteristics, And Health Effects: Are There Sufficient Data For Risk Assessment?, Avinash Kumar, Divine Nde, Chuqi Guo, Rashmi Pathak, Fox Foley, Syed Ahmad, Prakash Dangal, Farhana Hasan, Myron Lard, Ankit Aryal, Martine E. Mathieu-Campbell, Jennifer Irving, Oluwafeyikemi Ogunmusi, Jennifer Richmond-Bryant, Slawomir Lomnicki, Lavrent Khachatryan, Stephania A. Cormier, Tammy R. Dugas

Faculty Publications

Environmentally persistent free radicals (EPFRs) are stable free radicals formed on particulate matter (PM) through processes such as combustion and pyrolysis. These free radicals are generated on transition metal oxide surfaces in the presence of aromatic precursors. Exposure to EPFRs occurs primarily via inhalation of PM deriving from combustion, traffic, industrial activities, and both indoor and outdoor burning. Other environmental factors that might generate EPFRs are radon, electronic and tobacco cigarettes. EPFRs exhibit unexpectedly long half-lives, ranging from several weeks to, in some cases, several years. EPFRs may be carbon-centered, oxygen-centered or mixed, identified by g-values exhibited in electron paramagnetic …

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

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.

Convergence Of The Planewave Approximations For Quantum Incommensurate Systems, Ting Wang, Huajie Chen, Aihui Zhou, Yuzhi Zhou, Daniel Massatt

Faculty Publications

Incommensurate structures come from stacking the single layers of low dimensional materials on top of one another with misalignment such as a twist in orientation. While these structures are of significant physical interest, they pose many theoretical challenges due to the loss of periodicity. This paper studies the physical observables of continuum Schrodinger operators for incommensurate systems. We characterize the density of states and local density of states in real and reciprocal spaces, and develop novel numerical methods to approximate them. In particular, we (i) justify the thermodynamic limit of the density of states and local density of states via …

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

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 …

Chemotherapy treatment-related side effects are common and increase the risk of suboptimal outcomes. Exercise interventions during cancer treatment improve self-reported physical functioning, fatigue, anxiety, and depression, but it is unclear whether these interventions improve important clinical outcomes, such as chemotherapy relative dose intensity. The National Cancer Institute funded the Exercise and Nutrition to Improve Cancer Treatment-Related Outcomes (ENICTO) Consortium to address this knowledge gap. This article describes the mechanisms hypothesized to underpin intervention effects on clinically relevant treatment outcomes, briefly outlines each project’s distinct research aims, summarizes the scope and organizational structure of ENICTO, and provides an overview of the …

What ‘Unexplored’ Means: Mapping Regions With Digitized Natural History Records To Look For ‘Biodiversity Blindspots’, Laymon Ball, Sheila Rodríguez-Machado, Diego Paredes-Burneo, Samantha Rutledge, David A. Boyd, David Vander Pluym, Spenser Babb-Biernacki, Austin S. Chipps, Rafet Öztürk, Yahya Terzi, Prosanta Chakrabarty

Faculty Publications

We examined global records of accessible natural history voucher collections (with publicly available data and reliable locality data) for terrestrial and freshwater vascular plants, fungi, freshwater fishes, birds, mammals, and herpetofauna (amphibians and reptiles) and highlight areas of the world that would be considered undersampled and sometimes called ‘unexplored’ (i.e., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. We also question what ‘unexplored’ may mean in these contexts and explain how replacing the term in favor of more nuanced phrasing (e.g., ‘biodiversity blindspots,’ which emphasizes the lack of publicly available data about specimens) can …

Targeting Bacterial Transcription Factors For Infection Control: Opportunities And Challenges, Ahmed Al-Tohamy, Anne Grove

Faculty Publications

The rising threat of antibiotic resistance in pathogenic bacteria emphasizes the need for new therapeutic strategies. This review focuses on bacterial transcription factors (TFs), which play crucial roles in bacterial pathogenesis. We discuss the regulatory roles of these factors through examples, and we outline potential therapeutic strategies targeting bacterial TFs. Specifically, we discuss the use of small molecules to interfere with TF function and the development of transcription factor decoys, oligonucleotides that compete with promoters for TF binding. We also cover peptides that target the interaction between the bacterial TF and other factors, such as RNA polymerase, and the targeting …

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 …

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 …
