(Wp 2024-02) Stratification Economics: Historical Origins And Theoretical Foundations, John B. Davis

Economics Working Papers

Stratification economics (SE) investigates how economies are organized around group inequalities, especially by race and gender but also by ethnicity, national origin, religion, sexual orientation, etc. Its historical origins and theoretical foundations have both a structural strand that addresses how and a social behavioral strand. SE's structural strand goes back to Ricardo and Marx regarding the relationship between growth and distribution, and then draws on recent economic theory of noncompeting groups and dual economy models of labor market segmentation. SE's structural strand produces an inequality-based understanding of economics' standard goods taxonomy. The social behavioral strand builds on Du Bois's psychological …

Quaternary Ammonia Compounds In Disinfectant Products: Evaluating The Potential For Promoting Antibiotic Resistance And Disrupting Wastewater Treatment Plant Performance, Zihao Lu, Anna K. Mahony, William A. Arnold, Christopher Marshall, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Quaternary ammonium compounds (QACs) are a class of compounds that were widely used as disinfectants during the COVID-19 pandemic and continue to be used as disinfecting agents. After consumer usage, QAC concentrations are diluted in wastewater as they enter wastewater treatment plants. At sub-inhibitory concentrations, QACs may have unintended repercussions, including increased antibiotic resistance and inhibition of process performance in wastewater treatment plants. This review first summarizes how QACs inhibit bacteria and then highlights the mechanisms by which QACs can promote antibiotic resistance in general. Reported environmental concentrations of QACs are compared to concentrations that are suspected to impact antibiotic …

Process Of Maintaining Self In Individuals Living With Systemic Sclerosis: A Grounded Theory Study Of American Women, Donald D. Miller, Jennifer J. Doering

College of Nursing Faculty Research and Publications

Background: People with chronic illnesses may struggle to adapt psychologically to the illness experience and have feelings of identity loss, self-diminishment, and biographical disruption. This may limit people’s ability to engage in optimal selfmanagement. Systemic sclerosis is a debilitating, stigmatizing, and life-limiting progressive chronic illness with significant disfiguring effects. Little is known about the identity management process in people with disfiguring and debilitating conditions such as systemic sclerosis.

Purpose: The purpose of this study was to generate a grounded theory explicating the process of maintaining a sense of self in people living with systemic sclerosis.

Methods: Fifteen women with systemic …

Communicating Socially Acceptable Risk Judgments: The Role Of Impression Information Insufficiency In The Risk Information Seeking And Processing Model, Timothy K.F. Fung, Po Yan Lai, Robert Griffin

College of Communication Faculty Research and Publications

The COVID-19 pandemic has created uncertainty and controversy around risk-related issues such as vaccine mandates. People expressing their opinions on these issues to important others, such as employers, may face significant consequences, such as rewards or rejection. Therefore, people may try to find, avoid, or use information in a way that helps them express risk judgments that are socially acceptable in different social situations. This study investigated how people seek, avoid, and process risk information when they are concerned about their impression management. It also introduced the concept of impression information insufficiency (the perceived gap between the information one has …

(Wp 2024-01) Douglass North, New Institutional Economics, And Complexity Theory, John B. Davis, Mauro Boianovsky

Economics Working Papers

Douglass North was central to the emergence of New Institutional Economics. Less well known are his later writings where he became interested in complexity theory. He attended the second economics complexity conference at the Santa Fe Institute in 1996 on how the economy functions as a complex adaptive system, and in his 2005 Understanding the Process of Economic Change incorporated this thinking into his argument that market systems depend on how institutions evolve. North also emphasized in the 2005 book the role belief played in evolutionary processes, and drew on cognitive science, especially the famous ‘scaffolding’ idea of cognitive scientist …

The Effects Of Lead, Copper, And Iron Corrosion Products On Antibiotic Resistant Bacteria And Antibiotic Resistance Genes, Veronika Folvarska, San Marie Thomson, Zihao Lu, Maya Adelgren, Adam Schmidt, Ryan J. Newton, Yin Wang, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Antibiotic resistance is a public health crisis. Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are present in drinking water distribution systems. Metals are known selective pressures for antibiotic resistance, and metallic corrosion products are found within drinking water distribution systems due to the corrosion of metal pipes. While corrosion products are a source of metals, the impact of specific corrosion products on antibiotic resistance has not been investigated. The objective of this study was to determine the impact of six corrosion products—CuO, Cu₂O, Pb₅(PO₄)₃OH, β-PbO₂, Fe₃O …

(Wp 2023-06) Richard Arena On Sraffa And Wittgenstein, John B. Davis

Economics Working Papers

This paper discusses Richard Arena’s insightful and original contributions to interpreting the important interaction between Piero Sraffa and Ludwig Wittgenstein. It discusses this in terms of dilemmas they each encountered in transitions in their thinking in the 1930s, emphasizes the influence of Sraffa’s unpublished “Surplus Product” text, compares Sraffa’s critique of “natural science point of view” and Wittgenstein’s critique of logical form, and compares Sraffa’s later understanding of the relationship between production and distribution and Wittgenstein’s later understanding of forms of life and language-games. The paper argues this thinking opened up a approach to economic philosophy in connection with the …

Peroxi-Electrocoagulation For Treatment Of Trace Organic Compounds And Natural Organic Matter At Neutral Ph, Donald R. Ryan, Patrick J. Mcnamara, Claire K. Baldus, Yin Wang, Brooke K. Mayer

Civil and Environmental Engineering Faculty Research and Publications

Iron-based oxidation technologies can be advantageous for mitigating trace organic compounds (TOrCs) during water and wastewater treatment due to their production of hydroxyl radicals. However, iron-based oxidation often occurs at acidic pH to promote Fenton's reaction, which limits the processes' feasibility for treatment applications. This study focused on utilizing iron-electrocoagulation (EC) paired with ex situ H₂O₂ addition (peroxi-electrocoagulation [EC:H₂O₂]) to promote oxidative reactions at neutral pH conditions. The hydroxyl radical probe para-chlorobenzoic acid (pCBA) was used to gauge oxidant activity and serve as a representative TOrC. The impact of water …

(Wp 2023-05) Measuring The Effects Of Unconventional Monetary Policy Tools Under Adaptive Learning, Stephen J. Cole, Sungjun Huh

Economics Working Papers

We compare the economic effects of forward guidance and quantitative easing utilizing the four-equation New Keynesian model of Sims, Wu, and Zhang (2023) with agents forming expectations via an adaptive learning rule. The results indicate forward guidance can have a greater influence on macroeconomic variables compared to quantitative easing, suggesting that forward guidance may have contributed to the high inflation rate after the COVID-19 related recession. Adaptive learning agents estimate a higher effect of forward guidance on the economy leading to a greater impact on expectations, and thus, contemporaneous inflation. However, the performance gap between forward guidance and quantitative easing …

(Wp 2023-04) Living Up To Expectations: Central Bank Credibility, The Effectiveness Of Forward Guidance, And Inflation Dynamics Post-Global Financial Crisis, Stephen J. Cole, Enrique Martínez-García, Eric Sims

Economics Working Papers

This paper studies the effectiveness of forward guidance when central banks have imperfect credibility. Exploiting unique survey-based measures of expected inflation, output growth, and interest rates, we estimate a small-scale New Keynesian model for the United States and other G7 countries plus Spain allowing for deviations from full information rational expectations. In our model, the key parameter that aggregates heterogeneous expectations captures the central bank's credibility and affects the over-all effectiveness of forward guidance. We find that the central banks of the U.S., the U.K., Germany, and other major advanced economies have similar levels of credibility (albeit far from full …

(Wp 2023-03) Economics Imperialism And Economic Imperialism: Two Sides Of The Same Coin, Angela Ambrosino, Mario Cedrini, John B. Davis

Economics Working Papers

We argue that in a core-periphery economic world economics imperialism as advanced by the postwar Chicago School and economic imperialism led by the economies of the north are two sides of the same coin. We first review the parallelism between postwar capitalism’s core-periphery expansion of the north into the south and the Chicago’s theory of economics imperialism. We then distinguish four forms of relationships between different disciplines, and using Rodrik’s augmented global capitalism trilemma argue Chicago adopts his Golden Straitjacket pathway, both for north-south capitalist expansion and core mainstream economics’ orientation toward other social science disciplines. The paper then uses …

Antibiotic Resistance In Urban Stormwater: A Review Of The Dissemination Of Resistance Elements, Their Impact, And Management Opportunities, Kassidy N. O'Malley, Walter M. Mcdonald, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

The public health crisis of antibiotic resistance is a growing threat across the world that is only expected to intensify in the coming years. The cycling of antibiotic resistance genes (ARGs) in the environment via urban stormwater runoff is one means by which humans are exposed to resistant bacteria as traditional gray stormwater infrastructure facilitates the transport of resistance elements into water bodies utilized by the public. In this review, existing research on the occurrence of ARGs in urban stormwater runoff is critically reviewed with the goal of determining the role of stormwater in the dissemination and development of antibiotic …

Impact Of Corrosion Inhibitors On Antibiotic Resistance, Metal Resistance, And Microbial Communities In Drinking Water, Lee K. Kimbell, Emily Lou Lamartina, Stan Kohls, Yin Wang, Ryan J. Newton, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Corrosion inhibitors, including zinc orthophosphate, sodium orthophosphate, and sodium silicate, are commonly used to prevent the corrosion of drinking water infrastructure. Metals such as zinc are known stressors for antibiotic resistance selection, and phosphates can increase microbial growth in drinking water distribution systems (DWDS). Yet, the influence of corrosion inhibitor type on antimicrobial resistance in DWDS is unknown. Here, we show that sodium silicates can decrease antibiotic resistant bacteria (ARB) and antibiotic-resistance genes (ARGs), while zinc orthophosphate increases ARB and ARGs in source water microbial communities. Based on controlled bench-scale studies, zinc orthophosphate addition significantly increased the abundance of ARB …

Effectiveness Of A Postpartum Breastfeeding Protocol For Avoiding Pregnancy Data, Mary Schneider, Richard Fehring, Thomas Paul Bouchard

Randomized Comparison of Two Internet-Supported Methods of Natural Family Planning

The uses of cervical mucus and basal body temperature as indicators of return to fertility postpartum have resulted in high unintended pregnancy rates. In 2013, a study found that when women used urine hormone signs in a postpartum/breastfeeding protocol this resulted in fewer pregnancies. To improve the original protocol's effectiveness, three revisions were made: (1) women were to increase the number of days tested with the Clearblue Fertility Monitor, (2) an optional second luteinizing hormone test could be done in the evening, and (3) instructions were given to manage the beginning of the fertile window for the first six cycles …

(Wp 2023-02) What Are Reflexive Economic Agents? Position-Adjustment, Slam, And Self-Organization, John B. Davis

Economics Working Papers

If mainstream economics and its view of economic agents is designed for a world in which reflexivity and feedback processes in the economy are ‘tamed’ and predictable, how are we to understand economic agents in a world in which reflexivity is ‘untamed’ and economies regularly exhibit unexpected fluctuations and significant nonlinearities? In a nonlinear world, economies evolve and undergo critical phase transitions from one form of organization to another. It seems, then, that we should also expect economic agents to evolve and undergo critical phase transitions from being one type of agent to another just as we observe that economies …

Nuclear And Cytoplasmic Spatial Protein Quality Control Is Coordinated By Nuclear–Vacuolar Junctions And Perinuclear Escrt, Emily M. Sontag, Fabián Morales-Polanco, Jian-Hua Chen, Gerry Mcdermott, Patrick T. Dolan, Dan Gestaut, Mark A. Le Gros, Carolyn Larabell, Judith Frydman

Biological Sciences Faculty Research and Publications

Effective protein quality control (PQC), essential for cellular health, relies on spatial sequestration of misfolded proteins into defined inclusions. Here we reveal the coordination of nuclear and cytoplasmic spatial PQC. Cytoplasmic misfolded proteins concentrate in a cytoplasmic juxtanuclear quality control compartment, while nuclear misfolded proteins sequester into an intranuclear quality control compartment (INQ). Particle tracking reveals that INQ and the juxtanuclear quality control compartment converge to face each other across the nuclear envelope at a site proximal to the nuclear–vacuolar junction marked by perinuclear ESCRT-II/III protein Chm7. Strikingly, convergence at nuclear–vacuolar junction contacts facilitates VPS4-dependent vacuolar clearance of misfolded cytoplasmic …

Economic Anxiety Among Contingent Survey Workers, Meghan Condon, Amber Wichowsky

Political Science Faculty Research and Publications

Psychologists and other social scientists increasingly conduct experiments with online convenience samples from Amazon’s Mechanical Turk Marketplace (MTurk). MTurk and population-based samples differ in well-documented ways, but whether or not compositional differences are problematic for experiments remains controversial. We highlight a critically important characteristic that is likely to interact with many experimental treatments in the psychological and behavioral sciences, and that has not been identified by other studies of MTurk samples: economic anxiety. We document a sizable difference between contingent survey workers and the general population and explain the ways in which economic anxiety is likely to interact with experimental …
