Biological Lags And Market Dynamics In Vertically Coordinated Food Supply Chains: Hpai Impacts On U.S. Egg Prices, James L. Mitchell, Jada M. Thompson, Trey Malone

Department of Agricultural Economics Faculty Publications

It is well known that livestock production involves long biological lags. Failure to account for these biological lags can result in the misspecification of supply chain relationships and adjustments to market shocks, which can have significant implications for policy decisions. An example is the 2022 Highly Pathogenic Avian Influenza (HPAI) event that caused high mortality rates in domestic poultry supply chains and reduced egg production. We use the 2022–2023 HPAI event to highlight the implications of misspecification of disease dynamics in agri-food systems. Specifically, we examine the impact of HPAI on U.S. egg prices in 2022–2023. To do this, we …

Harold Bell Wright’S Civil Religion: God And The Groceryman, John J. Han

KAUPA Letters

As Harold Bell Wright’s novel God and the Groceryman (1927)—a sequel to The Calling of Dan Matthews—opens, Dan appears as a millionaire miner in Kansas City. Having accumulated sufficient wealth, he promotes “a practical Christianity” aimed at saving America “by the worship of God” in the imaginary Ozarks city of Westover. In the novel, the word church appears 450 times, but the term mainly highlights how the main character’s ministry has little to do with institutional Christianity. The words denomination and denominational appear 318 times in the novel, but Wright uses them in a negative sense, which reflects his Restorationist …

The Acoustics Of Absorbers Comprising A Flexible Perforated Membrane Backed By A Stack Of Granular Material, Zhuang Mo, Guochenhao Song, Huawei Yang, Tongyang Shi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

It has been found that when a layer of activated carbon partially fills the space behind a finite, edge-constrained, tensioned impermeable membrane, the absorption peaks due to the modal response of the membrane can be significantly enhanced in the low frequency range. In the present work, the modeling aspects of the latter work have been extended to allow the membrane to be both tensioned and flexurally-stiff, and further, to be micro-perforated, thus expanding the treatment design space. Secondly, the particle layer behind the membrane is modeled by using a two-dimensional finite difference implementation of the Biot poro-elastic theory which then …

Centerless? Making Sense Of Disruptions In The Graduate Writing Center, Shannon Mcclellan Brooks

The Writing Center Journal

This critical self-reflection is not a success story; rather, it is an effort of decolonial thinking that reckons with the idea, experience, and practice of centerlessness during pandemic-induced online transitions and operations in a graduate writing center (GWC). By tracing the contours of a series of interlocking disruptions the author and her graduate writing center community experienced during COVID-19, this article brings into sharp focus present colonial legacies inhibiting effective developments, moves, and adaptations to the GWC physical center space and praxis. Through retrospectively following pandemic-induced disruptions to her center, the author critically engages how epistemologies of coloniality and modernity …

Photodynamic Treatment Of Staphylococcus Aureus With Non-Iron Hemin Analogs In The Presence Of Hydrogen Peroxide, Badhu Prashanthika Sivasubramaniam, Benjamin M. Washer, Yuichiro Watanabe, Kathryn E. Ragheb, J. Paul Robinson, Alexander Wei

Department of Chemistry Faculty Publications

Bacteria subjected to antiseptic or antibiotic stress often develop tolerance, a trait that can lead to permanent resistance. To determine whether photodynamic agents could be used to counter tolerance, we evaluated three non-iron hemin analogs (M-PpIX; M = Al, Ga, In) as targeted photosensitizers for antimicrobial photodynamic inactivation (aPDI) following exposure to sublethal H2O2. Al-PpIX is an active producer of ROS whereas Ga- and In-PpIX are more efficient at generating singlet oxygen. Al- and Ga-PpIX are highly potent aPDI agents against S. aureus and methicillin-resistant strains (MRSA) with antimicrobial activity (3 log reduction in colony-forming units) at nanomolar concentrations. The …

Department of Curriculum and Instruction Faculty Publications

This exploratory analysis investigates the integration of ChatGPT in self-directed learning (SDL). Specifically, this study examines YouTube content creators’ language-learning experiences and the role of ChatGPT in their SDL, building upon Song and Hill's conceptual model of SDL in online contexts. Thematic analysis of interviews with 19 YouTubers and relevant video contents reveals distinct constructs of ChatGPT-integrated SDL, suggesting a reconceptualization and refinement of the SDL framework in the consideration of generative artificial intelligence (AI). This framework emphasizes critical aspects of utilizing ChatGPT as an SDL tool on two distinct levels: 1) the interactive relationships and interplay between learners’ personal …

Librarians As Faculty Developers: Shaping Disciplinary Classroom Experiences Through Information Literacy, Rachel Fundator, Michael Flierl, Clarence Maybee, Catherine Frasier Riehle, Maribeth Slebodnik, Amity Saha

Libraries Faculty and Staff Scholarship and Research

Involvement in faculty development is a promising approach to realizing academic libraries’ goals for information literacy. This study examines an inter-institutional program where librarians partnered with classroom instructors to create projects where students learned to use information in disciplinary ways. Using thematic analysis to examine participant materials, the findings suggest that the informed learning design model underpinning the program supported the creation of information-rich projects and fostered a sense of empowerment in librarians serving as faculty developers. Librarians can advance their role as educators by partnering with classroom instructors and presenting information literacy as a way to foster disciplinary learning.

The Ugliness Movement: Riot Grrrl's Use Of Ugliness As Feminist Subversion, Maylee Rollins

The Purdue Historian

In the 1990s, Riot Grrrl took the punk and feminist worlds by storm. It emphasized community and represented third-wave feminism in radical form. One particular example that represents the Riot Grrrl ideology well is ugliness. Throughout the movement, artists like Courtney Love and Kathleen Hanna used their musical platform to show the world their view of femininity. This involved body writing and reclaiming words used to degrade women, as well as dressing up in controversial outfits dubbed as “kinderwhore.” The aims of these women in using ugliness in their music were to subvert sexism in the punk scene and bring …

The Death Of Glasnost And Perestroika, Matthew B. Zechiel

The Purdue Historian

This paper covers the rise, fall, and ultimate destruction of the twin policies of Glasnost and Perestroika in Russia as they existed under the regimes of Gorbachev, Yeltsin, and Putin. After ascending to the position of General Secretary of the Communist Party of the Soviet Union, Mikhail Gorbachev attempted to liberalize the USSR through his policies of Glasnost and Perestroika. While these policies were not always followed under Gorbachev, it is clear that they were relatively successful at creating a freer society and state. However, these policies began to whither under Yeltsin, as the state, particularly the office of President, …

Where To Test A Nuclear Bomb, Tyler Kliegl

The Purdue Historian

The United States detonated three underground nuclear bombs on a far-off Alaskan island called Amchitka in the 1960s and 70s. The goal is to understand what the motive of the United States in selecting Amchitka over the endless potential sites to test at were. What makes a place worthy in being tested on, or unworthy in being left alone. How does the United States deal with resistance from locals and other organizations, fighting to prevent their tests.

Design Students’ Perspectives On Safety Concerns When Designing Future Tourism Services, Minna Virkkula, Laura Hokkanen, Jonna Häkkilä

GSTC Academic Symposium - In conjunction with the GSTC Global Conference

The safety of services is essential part of a company's social responsibility. In the tourism industry, ensuring the safety of services is crucial, but often overlooked in the design process. Incorporating safety aspects during the initial design phase can eliminate potential safety issues and improve quality of the services. By addressing safety concerns early on, unnecessary worries related to activities and services can be resolved. This paper examines the design perspective on safety in Lapland outdoor activities.
