The Calculated Photon: Visualization Of A Quantum Field, Martin K. Ligare, Ryan Oliveri

Faculty Journal Articles

We calculate spatial localization and phase properties of spontaneously emitted photons. Our model is simple yet fully quantized: the emitting atom is a two-level atom located in a one-dimensional multimode optical cavity. Although the photon state vector does not have a position-space representation, the expectation value of the square of the electric field operator (intensity) is spatially localized and this pattern shifts at the speed of light. The emitted photon exhibits classical-like phase properties in the intensity expectation value when it ‘‘interferes with itself’’ after reflection. The phase properties of the emitted radiation are also evident at times sufficiently long …

Corruption, Remittances, And Public Goods: A Unified Framework, Luis Gautier, Puneet Vatsa

Economics Faculty Publications and Presentations

Remittances are an important source of income for the very countries afflicted by high levels of corruption. However, corruption undermines the development potential of remittances. With this in mind, we propose policy reforms that harness the potential of remittances while mitigating corruption. Unlike previous studies, we point to two channels: (1) the corrupt government’s trade-off between its financial interests (corruption), the provision of a public good, and the gains from a higher inflow of remittances; and (2) the household’s consumption of the public good relative to that of the privately obtained substitute of the public good.

Grounding Evaluation Capacity Development In Systems Theory, Sarah D. Klier, Raphael J. Nawrotzki, Nataly Salas-Rodríguez, Sven Harten, Charles B. Keating, Polinpapilinho F. Katina

Engineering Management & Systems Engineering Faculty Publications

While “systemic thinking” is popular in the context of capacity development and evaluation, there is currently a lack of understanding about the benefits to employing systems theory in evaluation capacity development. Systems theory provides a useful orientation to the work involved in complex systems (e.g. national evaluation systems). This article illustrates how evaluation capacity development practitioners can use systems theory as a conceptual tool to gain a better understanding of the functional aspects and interrelationships present within a given evaluation system. Specifically, the systems theory perspective can help elucidate the reasons for the success or failure of a given evaluation …

Robust Testing Of Paired Outcomes Incorporating Covariate Effects In Clustered Data With Informative Cluster Size, Sandipan Dutta

Mathematics & Statistics Faculty Publications

Paired outcomes are common in correlated clustered data where the main aim is to compare the distributions of the outcomes in a pair. In such clustered paired data, informative cluster sizes can occur when the number of pairs in a cluster (i.e., a cluster size) is correlated to the paired outcomes or the paired differences. There have been some attempts to develop robust rank-based tests for comparing paired outcomes in such complex clustered data. Most of these existing rank tests developed for paired outcomes in clustered data compare the marginal distributions in a pair and ignore any covariate effect on …

On The Implementation And Further Validation Of A Time Domain Boundary Element Method Broadband Impedance Boundary Condition, Fang Q. Hu, Douglas M. Nark

Mathematics & Statistics Faculty Publications

A time domain boundary integral equation with Burton-Miller reformulation is presented for acoustic scattering by surfaces with liners in a uniform mean flow. The Ingard-Myers impedance boundary condition is implemented using a broadband multipole impedance model and converted into time domain differential equations to augment the boundary integral equation. The coupled integral-differential equations are solved numerically by a March-On-in-Time (MOT) scheme. While the Ingard-Myers condition is known to support Kelvin-Helmholtz instability due to its use of a vortex sheet interface between the flow and the liner surface, it is found that by neglecting a second derivative term in the current …

Tick Transmission Of Borrelia Burgdorferi To The Murine Host Is Not Influenced By Environmentally Acquired Midgut Microbiota, Sukanya Narasimhan, Nallakkandi Rajeevan, Morven Graham, Ming-Jie Wu, Kathleen Deponte, Solenne Marion, Orlanne Masson, Anya J. O'Neal, Daniel E. Sonenshine, Erol Fikrig

Biological Sciences Faculty Publications

Background

Ixodes scapularis is the predominant tick vector of Borrelia burgdorferi, the agent of Lyme disease, in the USA. Molecular interactions between the tick and B. burgdorferi orchestrate the migration of spirochetes from the midgut to the salivary glands—critical steps that precede transmission to the vertebrate host. Over the last decade, research efforts have invoked a potential role for the tick microbiome in modulating tick-pathogen interactions.

Results

Using multiple strategies to perturb the microbiome composition of B. burgdorferi-infected nymphal ticks, we observe that changes in the microbiome composition do not significantly influence B. burgdorferi migration from the midgut, invasion of …

Generation(Al) Matters: Story, Lens, And Tone, Louise Weatherbee Phelps

English Faculty Publications

This essay tells a story of how “generation” came to matter in rhetoric and composition/writing studies; analyzes and advocates for “generation” as a lens through which to examine disciplinary studies and activities; and considers how we can productively engage in generational relations between individuals and groups. It adopts a framework of “hospitality” (adapted from Richard and Janis Haswell) to develop a concept of “cross-generational relations” as an aspirational category. An ethic of hospitality is proposed to facilitate respectful, productive relations among generational groups, which recognize and enact interdependence but allow for a wide range of stances and strategies of interaction …

Artists As Assets: Labor And Capital In The Unity Asset Store, D'An Knowles Ball

English Faculty Publications

The Unity Asset Store sells amateur designers and artists a promise of being able to participate in an idealized, rationalized vision of how the game design industry operates. However, the Unity Asset Store depends on marketing the content created by amateur artists in ways that require the artists to essentially package their work as labor and to mask their role as artists. This essay views labor and capital in the Unity Asset Store through a Marxist lens, informed by Kline, Dyer-Witheford, and de Peuter's (2003) model of technological, cultural, and marketing forces as "three circuits of interactivity" in the mediatized …

Rethinking Data: Algorithms, Black Boxes, And Bias Through The Data Atm, Joshua Nieubuurt

English Faculty Publications

For nearly all of history things, creatures, and people came and went; leaving little, if anything, behind in their wake. Life in the 21st century has changed this natural pattern of existence, blurring the lines of what it is (and what it means) to dwell within the world. Physical things and people are now existing simultaneously in the digital realms as doppelgängers composed of coded data. Now, things and people are both embodied and disembodied: simultaneously. Data, individual and collective, pours into the digital oceans; a tumultuous sea of [dis]embodied-being translated into the language of electricity and silicon. The forms …

The Role Of Response Efficacy And Risk Aversion In Promoting Compliance During Crisis, Veronica L. Thomas, Hooman Mirahmad, Grace Kemper

Marketing Faculty Publications

This research examines consumers' compliance with behaviors that focus on preventing the spread of COVID‐19. Drawing on Protection Motivation Theory and research on efficacy, we find that, during a pandemic, consumers who have higher perceptions of response efficacy are less likely to engage in risky consumption behaviors (Study 1) and more likely to engage in protective consumption behaviors (Study 2). This effect is moderated by risk aversion, such that as risk aversion increases, COVID‐compliant behaviors increase even when consumers do not believe in their ability to effectuate change. Further, the relationship between response efficacy and COVID‐compliant behaviors is mediated by …

The Acute Physiological Response Of Polar Bears To Helicopter Capture, John P. Whiteman, Henry J. Harlow, George M. Durner, Eric V. Regehr, Steven C. Amstrup, Anthony M. Pagano, Merav Ben-David

Biological Sciences Faculty Publications

Many wildlife species are live captured, sampled, and released; for polar bears (Ursus maritimus) capture often requires chemical immobilization via helicopter darting. Polar bears reduce their activity for approximately 4 days after capture, likely reflecting stress recovery. To better understand this stress, we quantified polar bear activity (via collar‐mounted accelerometers) and body temperature (via loggers in the body core [T_abd] and periphery [T_per]) during 2–6 months of natural behavior, and during helicopter recapture and immobilization. Recapture induced bouts of peak activity higher than those that occurred during natural behavior for 2 of 5 bears, …

All-Inclusive Coral Reef Restoration: How The Tourism Sector Can Boost Restoration Efforts In The Caribbean, Macarena Blanco-Pimentel, Nicolas R. Evensen, Camilo Cortés-Useche, Johanna Calle-Triviño, Daniel J. Barshis, Victor Galván, Erika Harms, Megan K. Morikawa

Biological Sciences Faculty Publications

Following a strong decline in the health of Caribbean coral reefs in the 1970s, disease outbreaks, overfishing, and warming events have continued to push these reefs towards a point of no return. As such, researchers and stakeholders have turned their attention to restoration practices to overcome coral recovery bottlenecks on Caribbean reefs. However, successful restoration faces many challenges, including economical and logistical feasibility, long-term stability, and biological and ecological factors yet to fully understand. The tourism sector has the potential to enhance and scale restoration efforts in the Caribbean, beyond simple financial contributions. Its strengths include long-term presence in several …

Geomorphic Gradients In Shallow Seagrass Carbon Stocks, Jahson Berhane Alemu, Siti Maryam Yaakub, Erik S. Yando, Rachel Yu San Lau, Cheng Chang Lim, Jun Yu Puah, Daniel A. Friess

Biological Sciences Faculty Publications

Seagrass meadows are important sinks of organic carbon (C_org), in particular the near-surface C_org pool (≤ 15 cm) compared to deeper sediments. Near-surface carbon is highly susceptible to disturbance and loss to the atmosphere, however, inadequate accounting for variability in this pool of carbon limits their uptake into carbon accounting frameworks. We therefore investigated the spatial variability in seagrass near-surface C_org and biomass C_org across different geomorphic (estuary, lagoonal and reef-associated) and community typologies (pioneer and persistent). Near-surface C_org stock in vegetated areas (25.78 Mg C_org ha⁻¹ ± 26.64) was twice that …

Observations Of Delayed Changes In Respiratory Function Among Allergy Clinic Patients Exposed To Wildfire Smoke, James Blando, Michael Allen, Hadiza Galadima, Timothy Tolson, Muge Akpinar-Elci, Mariana Szklo-Coxe

Community & Environmental Health Faculty Publications

Wildfires have increased in frequency and magnitude and pose a significant public health challenge. The principal objective of this study was to assess the impact of wildfire smoke on respiratory peak flow performance of patients exposed to two different wildfire events. This longitudinal study utilized an observational approach and a cohort study design with a patient-level clinical dataset from a local outpatient allergy clinic (n = 842). Meteorological data from a local weather station served as a proxy for smoke exposure because air quality measurements were not available. This study found that there were decreases in respiratory peak flow among …

Network Orientation, Organisational Improvisation And Innovation: An Empirical Examination, Ao Zhang, Weiyong Zhang

Information Technology & Decision Sciences Faculty Publications

In today's highly competitive world market, businesses can hardly maintain their competitiveness without strong innovation abilities. In the past, many Chinese enterprises have enjoyed success through imitation. But to continue to succeed in a global marketplace, they must develop ambidextrous innovation abilities. The resource‐based theory eloquently posits that competitive advantage is associated with different and heterogeneous resources. To obtain such resources, firms must establish an external network to acquire necessary knowledge and skills. In this paper, we develop a theoretical model linking network orientation, organisational improvisation, ambidexterity and competitive tension. We postulate that organisational improvisation has a mediating effect and …

The Online Ordering Behaviors Among Participants In The Oklahoma Women, Infants, And Children Program: A Cross-Sectional Analysis, Qi Zhang, Kayoung Park, Junzhou Zhang, Chuanyi Tang

Community & Environmental Health Faculty Publications

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a nutrition assistance program in the United States (U.S.). Participants in the program redeem their prescribed food benefits in WIC-authorized grocery stores. Online ordering is an innovative method being pilot-tested in some stores to facilitate WIC participants' food benefit redemption, which has become especially important in the COVID-19 pandemic. The present research aimed to examine the online ordering (OO) behaviors among 726 WIC households who adopted WIC OO in a grocery chain, XYZ (anonymous) store, in Oklahoma (OK). These households represented approximately 5% of WIC households who redeemed …

Application Of Chemostratigraphic Methods To Floodplain Alluvial Deposits Within The Big Harris Creek Basin, North Carolina, Samantha N. Sullivan, Jerry R. Miller, Carmen L. Huffman

Chemistry & Biochemistry Faculty Publications

Big Harris Creek, North Carolina, possesses a geomorphic history and alluvial stratigraphic record similar to many drainages in southern Appalachian Piedmont. An approximately 1 km reach of Upper Stick Elliott Creek, a tributary to Big Harris Creek, was used herein to (1) explore the use of chemostratigraphic methods to define and correlate late Holocene alluvial deposits along this relatively uncontaminated rural stream containing legacy sediments (historic, anthropogenically derived deposits), and (2) interpret depositional floodplain processes within small (<10 km²), headwater drainages. The lithofacies within four floodplain sections were described in channel banks and sampled at about 5 cm intervals. …

Type-B Energetic Processes And Their Associated Scientific Implications, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

Recently, our work has identified two thermodynamically distinct types (A and B) of energetic processes naturally occurring on Earth. Type-A energy processes such as the classical heat engines, ATP hydrolysis, and many of the known chemical, electrical, and mechanical processes apparently follow well the second law of thermodynamics; Type-B energy processes, for example, the newly discovered thermotropic function that isothermally utilizes environmental heat energy to do useful work in driving ATP synthesis, follow the first law of thermodynamics (conservation of mass and energy) but do not have to be constrained by the second law, owing to its special asymmetric functions. …

On The Stratospheric Chemistry Of Midlatitude Wildfire Smoke, Susan Soloman, Kimberlee Dube, Kane Stone, Pengfei Yu, Doug Kinnison, Owen B. Toon, Susan E. Strahan, Karen H.

Massive Australian wildfires lofted smoke directly into the stratosphere in the austral summer of 2019/20. The smoke led to increases in optical extinction throughout the midlatitudes of the southern hemisphere that rivalled substantial volcanic perturbations. Previous studies have assumed that the smoke became coated with sulfuric acid and water and would deplete the ozone layer through heterogeneous chemistry on those surfaces, as is routinely observed following volcanic enhancements of the stratospheric sulfate layer. Here, observations of extinction and reactive nitrogen species from multiple independent satellites that sampled the smoke region are compared to one another and to model calculations. The …

Ozonized Biochar Filtrate Effects On The Growth Of Pseudomonas Putida And Cyanobacteria Synechococcus Elongatus Pcc 7942, Oumar Sacko, Nancy L. Engle, Timothy J. Tschaplinski, Sandeep Kumar, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

Background

Biochar ozonization was previously shown to dramatically increase its cation exchange capacity, thus improving its nutrient retention capacity. The potential soil application of ozonized biochar warrants the need for a toxicity study that investigates its effects on microorganisms.

Results

In the study presented here, we found that the filtrates collected from ozonized pine 400 biochar and ozonized rogue biochar did not have any inhibitory effects on the soil environmental bacteria Pseudomonas putida, even at high dissolved organic carbon (DOC) concentrations of 300 ppm. However, the growth of Synechococcus elongatus PCC 7942 was inhibited by the ozonized biochar filtrates at …

The HITRAN database is a compilation of molecular spectroscopic parameters. It was established in the early 1970s and is used by various computer codes to predict and simulate the transmission and emission of light in gaseous media (with an emphasis on terrestrial and planetary atmospheres). The HITRAN compilation is composed of five major components: the line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, experimental infrared absorption cross-sections (for molecules where it is not yet feasible for representation in a line-by-line form), collision-induced absorption data, aerosol indices of refraction, and general tables (including partition sums) that apply globally to the data. …

Armageddon Revisited: The 1973 Gubernatorial Election In Virginia, James R. Sweeney

History Faculty Publications

Threatening a lawsuit, Howell prepared a memorandum to NBC citing evidence of voters changing their votes to Godwin, because as one put it, "A national network can't be wrong."⁷⁸ Howell's memorandum also mentioned an indirect tie of McGee to Godwin. Godwin constantly demanded that Howell disclose how he would replace the revenue under his tax plan.⁴³ Throughout the campaign, Godwin stressed inconsistencies between positions Howell took on various issues in 1973 and what he had said in the past. Godwin also cited Howell's endorsement of his candidacy for governor in 1965 and his comment in April that Godwin …

‘It All Comes From Me’: Bahu Begam And The Making Of The Awadh Nawabi, Circa 1765–1815, Nicholas J. Abbott

History Faculty Publications

This article examines the durable, yet largely overlooked, claims of Bahu Begam (1727–1815) to dynastic wealth and authority in the Awadh nawabi (1722–1856), a North Indian Mughal ‘successor state’ and an important client of the East India Company. Chief consort (khass mahal) to Nawab Shuja-ud-Daula (r. 1754–75) and mother to his successor Nawab Asaf-ud-Daula (r. 1775–97), Bahu Begam played a well-documented role in the regime’s tumultuous politics, particularly during Warren Hastings’s tenure as the Company’s governor-general (1773–85) and his later parliamentary impeachment. But despite her prominent political influence, little attention has been paid to the substance of her …
