Does The Use Of Simulation Significantly Impact Students’ Perceptions Of Their Air Traffic Control Knowledge And Skill?, Meron Lindenfeld, Jeanne Radigan, Michael Figuccio

Journal of Aviation Technology and Engineering

Simulation has served as an instructional supplement in education and training within various fields such as nursing, business, and flight training. Prior research studies have documented its usefulness. Simulation-based lessons have also been used for air traffic control (ATC) training, but little research has been conducted on the usefulness of simulation in this application. This study measured the level of influence that ATC simulation had on students’ perception of their ATC knowledge and skill level and their commitment to a career in ATC.

Data were collected by surveying students at four institutions of higher education after they completed ATC courses …

Capturing Children With Autism’S Engagement In Engineering Practices: A Focus On Problem Scoping, Hoda Ehsan, Monica E. Cardella

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

In the last two decades, pre-college engineering education has increased, with research on pre-college engineering education emerging as a nascent field. However, limited research, if any, has considered aspects of engineering thinking of children with neurodiversity. In line with calls for broadening participation in engineering education, consideration of neurodiverse children is critical. Among various neurodiverse conditions, the number of children with autism is rapidly growing. In addition, studies have shown that individuals with autism have the potential to perform well in activities that require systematizing abilities. Engineering is one such activity. Prior research has provided evidence of the importance of …

Ospemifene Displays Broad-Spectrum Synergistic Interactions With Itraconazole Through Potent Interference With Fungal Efflux Activities, Hassan E. Eldesouky, Ehab A. Salama, Tony R. Hazbun, Abdelrahman S. Mayhoub, Mohamed N. Seleem

Borch Department of Medicinal Chemistry and Molecular Pharmacology Faculty Publications

Azole antifungals are vital therapeutic options for treating invasive mycotic infections. However, the emergence of azole-resistant isolates combined with limited therapeutic options presents a growing challenge in medical mycology. To address this issue, we utilized microdilution checkerboard assays to evaluate nine stilbene compounds for their ability to interact synergistically with azole drugs, particularly against azole-resistant fungal isolates. Ospemifene displayed the most potent azole chemosensitizing activity, and its combination with itraconazole displayed broad-spectrum synergistic interactions against Candida albicans, Candida auris, Cryptococcus neoformans, and Aspergillus fumigatus (ΣFICI = 0.05–0.50). Additionally, in a Caenorhabditis elegans infection model, the ospemifene-itraconazole combination significantly reduced fungal …

In fall 2018, five research teams collected 9,776 pilot records from five regional airlines and analyzed these data. In the PSS 2018, the criteria for success were: ≥90% completions and ≤1 extra training event. In rank order, the following pilots were most successful in …

Tin @ Tio2 Core–Shell Nanoparticles As Plasmon-Enhanced Photosensitizers: The Role Of Hot Electron Injection, Xiaohui Xu, Aveek Dutta, Jacob Khurgin, Alexander Wei, Vladimir M. Shalaev, Alexandra Boltasseva

Department of Chemistry Faculty Publications

Metal–semiconductor heterostructures have attracted a lot of attention due to their ability to enhance photovoltaic and photocatalytic processes via plasmonic effects. Thus far, most of the proposed heterostructures are designed with noble metals and the potential of alternative plasmonic materials, such as titanium nitride (TiN), is not yet well explored. In this work, TiN@TiO2 core–shell nanoparticles (NPs) are synthesized and proposed as plasmon-enhanced photosensitizers for efficient singlet oxygen generation, with the focus on the role of hot electron injection. Excitation of dilute TiN@TiO2 NP dispersions by a 700 nm femtosecond-pulsed laser effectively converts ground-state oxygen into singlet oxygen (1O2), driven …

The Critical Role Of Humidity In Modeling Summer Electricity Demand Across The United States, Debora Maia-Silva, Rohini Kumar, Roshanak Nateghi

School of Industrial Engineering Faculty Publications

Cooling demand is projected to increase under climate change. However, most of the existing projections are based on rising air temperatures alone, ignoring that rising temperatures are associated with increased humidity; a lethal combination that could significantly increase morbidity and mortality rates during extreme heat events. We bridge this gap by identifying the key measures of heat stress, considering both air temperature and near-surface humidity, in characterizing the climate sensitivity of electricity demand at a national scale. Here we show that in many of the high energy consuming states, such as California and Texas, projections based on air temperature alone …

Advancing U.S. Latino Entrepreneurship: A New National Economic Imperative, Marlene Orozco, Alfonso Morales, Michael J. Pisani, Jerry I. Porras

Purdue University Press Book Previews

Advancing U.S. Latino Entrepreneurship examines business formation and success among Latinos by identifying arrangements that enhance entrepreneurship and by understanding the sociopolitical contexts that shape entrepreneurial trajectories. While it is well known that Latinos make up one of the largest and fastest growing populations in the U.S., Latino-owned businesses are now outpacing this population growth and the startup business growth of all other demographic groups in the country.

The institutional arrangements shaping business formation are no level playing field. Minority entrepreneurs face racism and sexism, but structural barriers are not the only obstacles that matter; there are agentic barriers and …

Being Portuguese In Spanish: Reimagining Early Modern Iberian Literature, 1580-1640, Jonathan William Wade

Purdue University Press Book Previews

Among the many consequences of Spain’s annexation of Portugal from 1580 to 1640 was an increase in the number of Portuguese authors writing in Spanish. One can trace this practice as far back as the medieval period, although it was through Gil Vicente, Jorge de Montemayor, and others that Spanish-language texts entered the mainstream of literary expression in Portugal. Proficiency in both languages gave Portuguese authors increased mobility throughout the empire. For those with literary aspirations, Spanish offered more opportunities to publish and greater readership, which may be why it is nearly impossible to find a Portuguese author who did …

Croatian Radical Separatism And Diaspora Terrorism During The Cold War, Mate Nikola Tokić

Purdue University Press Book Previews

Croatian Radical Separatism and Diaspora Terrorism During the Cold War examines one of the most active but least remembered groups of terrorists of the Cold War: radical anti-Yugoslav Croatian separatists. Operating in countries as widely dispersed as Sweden, Australia, Argentina, West Germany, and the United States, Croatian extremists were responsible for scores of bombings, numerous attempted and successful assassinations, two guerilla incursions into socialist Yugoslavia, and two airplane hijackings during the height of the Cold War. In Australia alone, Croatian separatists carried out no less than sixty-five significant acts of violence in one ten-year period. Diaspora Croats developed one of …

Adolescents’ Perceptions Of Contraception Access Through Pharmacies, Ashley H. Meredith, Emily Vahary, Tracey A. Wilkinson, Carolyn G. Meagher, Thomas Vielott, Mary A. Ott

Department of Pharmacy Practice Faculty Publications

Adolescent pregnancy is an important public health issue, and pharmacist prescribing has the potential to expand contraceptive access and decrease unintended pregnancy. However, little is known about acceptability and uptake of pharmacist prescribing among adolescents, particularly among youth in socially and politically conservative regions of the country. The study objective was to identify how young women in Indiana perceive pharmacist contraceptive prescribing. Participants were recruited from clinics and completed a simulated pharmacist contraception-prescribing encounter; a demographic and behavioral questionnaire; and an in-depth qualitative interview focused on adolescent perspectives on pharmacist prescribing. Data were analyzed using thematic analysis. Sixty young women …

Peptide-Modified Chondroitin Sulfate Reduces Coefficient Of Friction At Articular Cartilage Surface, Celina Twitchell, Tanaya Walimbe, Julie C. Liu, Alyssa Panitch

School of Chemical Engineering Faculty Publications

Osteoarthritis is a debilitating disease that results in pain and joint stiffness. Currently, steroidal and nonsteroidal anti-inflammatory drugs and supplements aimed at restoring lubrication to the affected joint are the most successful with respect to improving patient comfort. Due to the success in lubricating therapies, there exists a keen interest to develop better therapies that mimic how lubrication occurs naturally in the joint. Here we describe the results obtained using a chondroitin sulfate chain to which is conjugated peptides that bind to either hyaluronic acid (found in high concentrations in the synovial fluid) or collagen type II (present on the …

Microstructure-Based Numerical Simulation Of The Mechanical Properties And Fracture Of A Ti-Al3ti Core-Shell Structured Particulate Reinforced A356 Composite, Siming Ma, Xuezheng Zhang, Tijun Chen, Xiaoming Wang

Purdue University Libraries Open Access Publishing Fund

A microstructure-based numerical simulation is performed to understand themechanical properties and fracture of a Ti-Al3Ti core-shell structured particulate reinforced A356 composite ((Ti-Al3Ti)cs/A356). A series of twodimensional (2D) representative volume element (RVE) models are generated automatically by embedding Ti- Al3Ti core-shell structured particulates in an A356 matrix. Microstructure-based 2D RVE of monolithic Al3Ti particulate reinforced A356 composite (Al3Tip/A356) is also simulated for comparison. The ductile fracture of both Ti core and A356 matrix aswell as the brittle fracture of the Al3Ti shell are considered. The simulation confirms that the high elongation of the (Ti-Al3Ti)cs/A356 composite is attributed to the uniform distribution …

Social Scientists’ Testimony Before Congress In The United States Between 1946-2016, Trends From A New Dataset, Thomas V. Maher, Charles Seguin, Yongjun Zhang, Andrew P. Davis

Purdue University Libraries Open Access Publishing Fund

Congressional hearings are a venue in which social scientists present their views and analyses before lawmakers in the United States, however quantitative data on their representation has been lacking. We present new, publicly available, data on the rates at which anthropologists, economists, political scientists, psychologists, and sociologists appeared before United States congressional hearings from 1946 through 2016. We show that social scientists were present at some 10,347 hearings and testified 15,506 times. Economists testify before the US Congress far more often than other social scientists, and constitute a larger proportion of the social scientists testifying in industry and government positions. …

Behind The Curtain: The Cultural Capital Of Pilipino Cultural Nights, Xavier J. Hernandez

Journal of Southeast Asian American Education and Advancement

This study examines the phenomenon of Pilipino Cultural Nights in higher education through the lens of community cultural wealth. While in name, Pilipino Cultural Nights pay homage to the native culture of the Philippines, the processes through which these performances are produced and reproduced as annual traditions exhibit a distinct Filipino American cultural experience that is facilitated by the higher education environment. As under-represented and under-served students, Filipino American students utilize their various forms of community cultural wealth to create one of the most visible performances on their campus and a cornerstone coming of age experience for Filipino American youth. …

Cats And Conservationists: The Debate Over Who Owns The Outdoors, Dara M. Wald, Anna L. Peterson

New Directions in the Human-Animal Bond

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.

On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. …

Familiarity And Use Of Veterinary Services By Us Resident Dog And Cat Owners, Courtney Bir, Mario Ortez, Nicole Olynk Widmar, Chris Wolf, Charlotte Hansen, Frederic B. Ouedraogo

Department of Agricultural Economics Faculty Publications

Pet ownership, veterinary use, and beliefs regarding veterinary care were elicited through the use of a nationally representative survey of 997 U.S. residents. Fifty-one percent of respondents have or had a dog in the past five years and 37% have or had a cat in the past five years. Over ninety percent of cat and dog owners had visited a veterinarian at any time, but only about 40% visited a veterinarian annually. With the rise of options in veterinary medicine, including low-cost options for vaccines and spay/neuter, further study and analysis of pet-owners use of veterinary care is warranted. Fifty-four …

Perceptions Of Prominent Animal Welfare And Veterinary Care Organizations In The United States, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Chris Wolf

Department of Agricultural Economics Faculty Publications

U.S. residents’ perceptions of the impact of prominent animal welfare and veterinary care organizations on pet animal well-being and health care may not be linked to the organization’s stated mission and effectiveness in advancing it, but to the level of recognition people have for the groups. An online survey of 1000 U.S. residents was used to understand the perceived impact of organizations with self-stated dedication to pet animal well-being. Using a Likert-scale, respondents ranked 13 prominent organizations as having a low to high impact on pet animal well-being and health care. The American Society for the Prevention of Cruelty to …
