Therefore, a study of characteristics associated with passenger services is one of the most important measurements in the aviation industry. The objective of this study was to analyze the impact of passenger characteristics on the use of self-service technology (SST) for the check-in process at Sydney Kingsford Smith Airport. A survey was conducted online amid the COVID-19 pandemic for data collection. Based on the collected responses, this study analyzed the sociological and demographic characteristics of the passengers and situational factors related to characteristics …

A Decision-Support System For Economic Feasibility Of Subsurfaced Poultry Litter, Tim J. Stults, Michael P. Popp

Journal of Applied Farm Economics

Cattle (Bos spp.) producers routinely spread fertilizer or broadcast poultry (Gallus gallus L.) litter to improve forage production. With poultry litter widely available across the southeastern United States and being a cheaper source of plant nutrition than commercial fertilizer when proximal to application sites, the novel application of litter below the soil surface, while costly, allows for greater nutrient retention than broadcasting. Since quantifying costs and benefits of subsurfaced litter is complex, we develop and present a decision support spreadsheet for automated farm-scale model comparisons across modes of nutrient management. We compare subsurfaced litter to commercial fertilizer and broadcast litter …

Perennial Warm-Season Grass Forages Impact On Cow-Calf Profitability In The Fescue Belt, Kyle A. Brazil, Patrick D. Keyser, Andrew P. Griffith, Christopher N. Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

Incorporating a perennial warm- season grass (WSG) into tall fescue (Lolium arundina-ceum [Schreb.] Darbysh.) forage systems in the fescue belt can help avoid the effects of fescue toxicosis on beef cattle (Bos taurus) reproduction and animal performance and provide forage during summer when fescue production is low. However, little information is available on the economics of incorporating WSG into fescue-based forage systems. We developed a simulation model to compare profitability of three forage systems—100% tall fescue, 70% tall fescue/30% bermudagrass (Cynodon dactylon), and 70% tall fescue/ 30% switchgrass (Panicum virgatum)—while also comparing spring- …

Industrial Hemp Production And Market Risk Analysis In Oklahoma, Lixia H. Lambert, Amy D. Hagerman

Journal of Applied Farm Economics

Industrial hemp production has garnered producer attention as a potential summer crop alternative in Oklahoma. Farmers considering the inclusion of hemp, an emerging new crop, in their operations need to factor in risk and uncertainty. We conducted a risk analysis to determine the optimal allocation of land to conventional crops and hemp for a representative 1,000-acre wheat farm in northeastern Oklahoma under production and market risk. Target MOTAD (minimization of total absolute deviation) model was used to focus on downside risk and hemp market price uncertainty. Six double-cropping systems for double- cropped winter wheat were considered, including sorghum, sesame, hemp …

Revisiting The Relation Between Syntax, Action, And Left Ba44, David L. Kemmerer

Purdue University Libraries Open Access Publishing Fund

Among the many lines of research that have been exploring how embodiment contributes to cognition, one focuses on how the neural substrates of language may be shared, or at least closely coupled, with those of action. This paper revisits a particular proposal that has received considerable attention—namely, that the forms of hierarchical sequencing that characterize both linguistic syntax and goal-directed action are underpinned partly by common mechanisms in left Brodmann area (BA) 44, a cortical region that is not only classically regarded as part of Broca’s area, but is also a core component of the human Mirror Neuron System. First, …

Purdue University Libraries Open Access Publishing Fund

Psychiatric assistance dogs for military veterans with posttraumatic stress disorder (PTSD) currently make up over 19% of assistance dog partnerships globally. We conducted a systematic review of the literature relating to these partnerships, with specific aims to (1) summarize their characteristics, (2) evaluate the quality of existing evidence, and (3) summarize outcomes. A total of 432 records were independently screened (Cohen’s kappa = 0.90). Of these, 41 articles (29 peer-reviewed publications and 12 unpublished dissertations) met inclusion criteria. Data extraction was conducted to address the research aims, including a meta-analysis (quantitative outcomes) and meta-synthesis (qualitative outcomes). All peer-reviewed publications on …

Are U.S. Consumers Willing To Pay More By The Lake? An Analysis Of Preferences For Great Lakes Region Fish, April Athnos, Simone Valle De Souza, Kwamena Quagrainie, Chinonso Etumnu, William Knudson, Ronald E. Kinnunen, Paul Hitchens

Department of Agricultural Economics Faculty Publications

U.S. per capita seafood consumption is historically high due to population and income growth and consumer preference shifts toward healthy protein options. Despite this expansion, U.S. fisheries, especially those in the Great Lakes region, no longer fulfill domestic demand due to pressure on fish stocks and regulatory constraints. Instead, aquaculture and imports fill the gap. Rainbow trout, yellow perch, and walleye—three species historically produced in the North Central Region (NCR)—exemplify such trends. To expand marketing opportunities for NCR aquaculture producers, this study estimates willingness to pay (WTP) for these species and several search and credence fish attributes. We designed and …

The Relationships Between Social Media And Human Papillomavirus Awareness And Knowledge: Cross-Sectional Study, Soojung Jo, Keenan A. Pituch, Nancy Howe

School of Nursing Faculty Publications

Background: Human papillomavirus (HPV) is the most common sexually transmitted infection. HPV can infect both females and males, and it can cause many cancers, including anal, cervical, vaginal, vulvar, and penile cancers. HPV vaccination rates are lower than vaccination rates within other national vaccination programs, despite its importance. Research literature indicates that people obtain health-related information from internet sources and social media; however, the association between such health-seeking behavior on social media and HPV-related behaviors has not been consistently demonstrated in the literature. Objective: This study aims to examine the association between social media usage and HPV knowledge and HPV …

Smart Soft Contact Lenses For Continuous 24-Hour Monitoring Of Intraocular Pressure In Glaucoma Care, Jinyuan Zhang, Khunghun Kim, Ho Joong Kim, Dawn Meyer, Woohyun Park, Seul Ah Lee, Yumin Dai, Bongjoong Kim, Haesoo Moon, Jay V. Shah, Keely E. Harris, Brett Collar, Kangying Liu, Pedro Irazoqui, Hyowon Lee, Shin Ae Park, Pete S. Kollbaum, Bryan W. Boudouris, Chi Hwan Lee

Purdue University Libraries Open Access Publishing Fund

Continuous monitoring of intraocular pressure, particularly during sleep, remains a grand challenge in glaucoma care. Here we introduce a class of smart soft contact lenses, enabling the continuous 24-hour monitoring of intraocular pressure, even during sleep. Uniquely, the smart soft contact lenses are built upon various commercial brands of soft contact lenses without altering their intrinsic properties such as lens power, biocompatibility, softness, transparency, wettability, oxygen transmissibility, and overnight wearability. We show that the smart soft contact lenses can seamlessly fit across different corneal curvatures and thicknesses in human eyes and therefore accurately measure absolute intraocular pressure under ambulatory conditions. …

“My Companion Through The Pandemic”: The Importance Of The Human-Animal Bond During Covid-19, Christine Krouzecky, Jan Aden, Anastasiya Bunina, Katharina Hametner, Armin Klaps, Zuzana Kovacovsky, Nora Ruck, Birgit Ursula Stetina

People and Animals: The International Journal of Research and Practice

The COVID- 19 pandemic, due to its global biopsychosocial effects, encourages re-search regarding the promotion of health. Studies in this area concentrate on the human–animal bond as a source of physical and psychological well- being (Shoesmith et al., 2021). In this context, contradictory results have been reported, which on the one hand underline the positive influences of animal companionship on humans’ well- being (Ratschen et al., 2020), and on the other hand demonstrate contrary effects (Mueller et al., 2021). Based on inconsistent findings, the present study aimed to investigate to what extent the human–animal bond influences different psychosocial parameters (including …

The array has a linear component that extends about 30 km from north to south and a subarray to the south with a diameter of 10 km. The array was deployed from August 2019 to July 2020, which included the initial months of the Covid-19 pandemic. The northernmost seismic stations of the array are located within the southern end of one of the largest onshore wind farms in the world. To …

A Two-Phase Approach To Re-Calibrating Expensive Computer Simulation For Sex-Specific Colorectal Neoplasia Development Modeling, Carolina Vivas-Valencia, You Zhou, Aditya Sai, Thomas F. Imperiale, Nan Kong

Purdue University Libraries Open Access Publishing Fund

Medical evidence from more recent observational studies may significantly alter our understanding of disease incidence and progression, and would require recalibration of existing computational and predictive disease models. However, it is often challenging to perform recalibration when there are a large number of model parameters to be estimated. Moreover, comparing the fitting performances of candidate parameter designs can be difficult due to significant variation in simulated outcomes under limited computational budget and long runtime, even for one simulation replication.

Terrortimes, Terrorscapes: Continuities Of Space, Time, And Memory In Twentieth-Century War And Genocide, Volker Benkert, Michael Mayer

Purdue University Press Books

Terrortimes, Terrorscapes: Continuities of Space, Time, and Memory in Twentieth-Century War and Genocide investigates interconnections between space and violence throughout the twentieth century, and how such connections informed collective memory. The interdisciplinary volume shows how entangled notions of time and space amplified by memory narratives led to continuities of violence across different conflicts creating “terrortimes” and “terrorscapes” in their wake. The volume examines such continuities of violence with the help of an analytical framework built around different themes. Its first part, spatial and temporal continuities of violence, looks at contested spaces and ideas of national, ethnic, or religious homogeneity that …

Farmyard Animal Or Best Friend? Exploring Predictors Of Dog Vs. Pig Pet Speciesism, Sarah Gradidge, Magdalena Zawisza, Annelie J. Harvey, Daragh T. Mcdermott

People and Animals: The International Journal of Research and Practice

Despite dogs’ and pigs’ shared similarities, previous research indicates people favor dogs over pigs (known as “pet speciesism”). While pet speciesism has been empirically sup-ported, little is known about its predictors. This gap in the literature is problematic as urgent requirements to decrease meat consumption emphasize the pressing need to develop interventions to reduce pet speciesism and thus reduce meat consumption. However, to develop these interventions, we must first identify why people view pigs (vs. dogs) negatively. To begin addressing this gap, the current study utilized the stereotype content model to uniquely explore pet speciesism’s predictors. We recruited participants via …

Making The Case: Adding A Social Work Perspective To A Case Study In A Veterinary Practice, Paula Gerstenblatt, Diane Rhodes, Dorothea Ivey

People and Animals: The International Journal of Research and Practice

This article describes a case study exploration of a veterinary practice from the perspective of social work. Recognizing the stressful work of veterinary providers, including compassion fatigue and high suicide rates, the current study identified both a need for and the potential role of social workers in veterinary practice. Professionals were interviewed in an emergency/specialty practice. Using the interview data, the authors built a demonstrative case that underlines the vulnerability of veterinary professionals and the potential of social work to improve the quality of their work experiences and longevity.

Thermodynamic Limits Of Atmospheric Water Harvesting, Akshay K. Rao, Andrew J. Fix, Yun Chi Yang, David M. Warsinger

School of Mechanical Engineering Faculty Publications

Atmospheric water harvesting (AWH) is a rapidly emerging approach for decentralized water production, but current technology is limited by trade-offs between energy consumption and yield. The field lacks a common basis to compare different AWH technologies and a robust understanding of the performance impacts of water recovery, desorption humidity (for sorbent systems), and realistic component-level efficiencies. By devising a set of unifying assumptions and consistent parameters across technologies, we provide the first fair thermodynamic comparison over a broad range of environmental conditions. Using 2nd law analysis, or least work, we study the maximum efficiency for common open system AWH methods …

Middle School Engineering Teachers’ Enactments Of Pedagogies Rooted In Funds Of Knowledge And Translanguaging, Amy Wilson-Lopez, Jorge Acosta-Feliz

Journal of Pre-College Engineering Education Research (J-PEER)

Multilingual students should have opportunities to learn and do engineering in learning environments that foreground and sustain their cultural and linguistic practices. However, little is known about how middle school engineering teachers enact these environments. To address this gap in research and practice, this comparative case study describes the different ways in which two middle school technology and engineering teachers enacted pedagogies rooted in funds of knowledge and translanguaging. The teachers and research team engaged in a professional learning community, which focused on funds of knowledge and language-based pedagogies, for over one year. The teachers enacted pedagogies that incorporated principles …

Protein-Protein Interaction-Based High Throughput Screening For Adenylyl Cyclase 1 Inhibitors: Design, Implementation, And Discovery Of A Novel Chemotype, Tiffany S. Dwyer, Joseph B. O'Brien, Christopher P. Ptak, Justin E. Lavigne, Daniel P. Flaherty, Val J. Watts, David L. Roman

Purdue University Libraries Open Access Publishing Fund

Genetic and preclinical studies have implicated adenylyl cyclase 1 (AC1) as a potential target for the treatment of chronic inflammatory pain. AC1 activity is increased following inflammatory pain stimuli and AC1 knockout mice show a marked reduction in responses to inflammatory pain. Previous drug discovery efforts have centered around the inhibition of AC1 activity in cell-based assays. In the present study, we used an in vitro approach focused on inhibition of the protein-protein interaction (PPI) between Ca2+/calmodulin (CaM) and AC1, an interaction that is required for activation of AC1. We developed a novel fluorescence polarization (FP) assay focused on the …

Regulatory Compliance Of Labels And Product Information Leaflets For Medicines Distributed In The Private Sector In South Sudan, Stephen Mawa, Zita Ekeocha, Stephen Byrn, Kari Clase

BIRS Africa Technical Report Papers

Patient information leaflets (PILs) and labels are important for rational use of medicines as they provide additional information for patients on the medicines dispensed to them. In developing countries, this potential cannot be fully harnessed unless manufacturers provide medicines with labels and PILs that meet regulatory standards for content and user-friendliness. In South Sudan, it is not known if manufacturers uphold standards of these labels and PILs once their products are approved for distribution in the country.

This study explored the degree to which medicines distributed in South Sudan comply with regulatory requirements for labels and PILs. A cross-sectional survey …

Development Of An Assessment Tool For Good Distribution Practice For A Regulatory Agency In West Africa, Ukamaka Gladys Okafor, Zita Ekeocha, Stephen Byrn, Kari Clase, Solomon Shiihii

BIRS Africa Technical Report Papers

Good Distribution Practice (GDP) refers to the regulatory guidelines governing the wholesale and distribution of medicinal products to ensure that their quality and integrity are maintained throughout the supply chain from the manufacturer to the end users. A standard assessment tool for GDP is necessary in order to conduct a robust assessment on GDP on pharmaceutical industries. The observed agency’s policy and operational documents in addition to GDP Guidelines from World Health Organization and related organizations from various countries were reviewed. The observed Regulatory Agency does not have a separate assessment tool for GDP inspection. Few core GDP parameters are …

Dicamba Residue Persistence In Processing Tomato, Stephen L. Meyers, Jeanine Arana, Brandi C. Woolam, Nathaly Vargas, Laura Rodriguez, Luz Cardona

Department of Horticulture & Landscape Architecture Faculty Publications

There is zero tolerance for dicamba and dicamba metabolite residue in tomato (Solanum lycopersicum L.) fruit following exposure to dicamba. Field trials were conducted in 2020 and 2021 to determine the persistence of dicamba and metabolite (5-hydroxy dicamba and 3,6-dichlorosalicylic acid [DCSA]) residue in processing tomato shoots and fruits. Dicamba was applied 49 d after transplanting at 0, 0.53, 5.3, and 53 g ae ha−1. Tomato plants were harvested 5, 10, 20, 40, and 61 d after treatment (DAT). No 5-hydroxy dicamba was recovered from any sample. In 2020, the DCSA metabolite was detected from tomato shoot tissue when dicamba …

Butterhead Lettuce Variety Performance Trial In A Hydroponic Nft System, Leah Worth, Mary Rogers, Amanda Reardon

Midwest Vegetable Trial Reports

Lettuce (Lactuca sativa L.) is a cool-season crop grown exclusively for fresh consumption. The intensive consumer demand of pre-packaged and living butterheads in the market today has been supported by the shift of soil production methods to soilless hydroponic systems. Hydroponic varietal and fertility recommendations for living butterhead optimization are limited to small-scale growers, however. To increase understanding of butterhead lettuce fertility preference, we examined two different water reservoir fertility concentrations across 12 replicated nutrient film technique (NFT) systems planted with six butterhead lettuce varieties. No differences were found between varieties grown in either recommended or high fertility concentrations, …

Estimating External Tissue Support Parameters With Fluid-Structure Interaction Models From 4d Ultrasound Of Murine Thoracic Aortae, Tanmay C. Shidhore, Hannah L. Cebull, Megan C. Madden, Ivan C. Christov, Vitaliy L. Rayz, Craig J. Goergen

Weldon School of Biomedical Engineering Faculty Publications

Modeling of fluid-structure interactions (FSIs) between the deformable arterial wall and blood flow is necessary to obtain physiologically realistic computational models of cardiovascular systems. However, lack of information on the nature of contact between the outer vessel wall and surrounding tissue presents challenges in prescribing appropriate structural boundary conditions. Imaging techniques used to visualize wall deformation in vivo may be useful for estimating simulation parameters that capture the effects of both vascular composition and surrounding tissue support on the vessel wall displacement. Here, we present a method to calibrate external tissue support parameters in FSI simulations against four-dimensional ultrasound (4DUS) …

Perception Versus Reality: How Do Older Drivers Self-Perceive Their Own Driving Abilities?, Mackenzie Richards

American Journal of Rising Scholar Activities

As the general population ages worldwide, the percentage of drivers aged 65 years and older continues to increase. By the year 2030, one quarter of drivers are projected to be represented in this age category. As a result, it is imperative to continue research efforts involving older adults. At the same time, leading car manufacturers are developing semi- and fully- autonomous vehicles at a rapid rate, which are expected to be available to the public in the next few years. Several research gaps exist regarding older adults’ feelings towards this new technology. However, without a thorough understanding of how older …
