Access Control At Major/Minor Road Intersection Through Cav In Mixed Traffc, Ping Yi

Center for Connected and Automated Transportation

Roadway intersections are among the major causes of traffic congestion besides lane reduction bottlenecks. When a major road intersects a minor road at an unsignalized intersection without the control of a traffic signal, the mainline vehicles are given priority over the minor road vehicles to go through the intersection, and the latter can only enter or cross the intersection when there is a sufficient gap between successive vehicles on the major road. Connected and automated vehicles (CAV) are packed with tracking and lane-keeping assistance and adaptive speed control to ensure that vehicles do not collide while reducing traffic congestion. This …

Department of Agricultural Economics Faculty Publications

The location of production and processing has had an increasingly prominent role in discussions regarding food systems today. Acknowledging the increasing importance, we study consumer preferences for and perception of local products with a particular focus on how willingness to pay (WTP) for local origin indication differs across products, types of designations, and rurality of the individual's geographic location. Using data collected through an online survey, we focused on Indiana residents’ preferences for sweet corn and Barbecue (BBQ) sauce with the sample representing both rural and urban consumers across all twelve economic growth regions in the state. Results reveal significant …

Towards A Posthumanist Sociomaterial Conceptualization Of Intercultural Rhetoric, Amir Kalan

Journal of Rhetoric, Professional Communication, and Globalization

Intercultural rhetoric has a human-centered view of culture and considers humans’ ethnicities, beliefs, and social practices as crucial components of rhetorical traditions. Conceptualizing a posthumanist sociomaterial approach to intercultural rhetoric, this article suggests that writing across cultures can be viewed as rhetorical transition between two sociomaterial networks with non-human, as well as human, factors. It explains that posthuman intercultural rhetoric can turn into a field where researchers study political, economic, and administrative networks in which texts are funded, constructed, regulated, disseminated, sold, bought, and cited. This area of writing studies would be interested in how rhetoric is constructed and used …

Dynamics Of Nanocluster Aerosol In The Indoor Atmosphere During Gas Cooking, Satya S. Patra, Jinglin Jiang, Xiaosu Ding, Chunxu Huang, Emily K. Reidy, Vinay Kumar, Paige Price, Connor Keech, Gerhard Steiner, Philip Stevens, Nusrat Jung, Brandon E. Boor

Purdue University Libraries Open Access Publishing Fund

Nanocluster aerosol (NCA: particles in the size range of 1–3 nm) are a critically important, yet understudied, class of atmospheric aerosol particles. NCA efficiently deposit in the human respiratory system and can translocate to vital organs. Due to their high surface area-to-mass ratios, NCA are associated with a heightened propensity for bioactivity and toxicity. Despite the human health relevance of NCA, little is known regarding the prevalence of NCA in indoor environments where people spend the majority of their time. In this study, we quantify the formation and transformation of indoor atmospheric NCA down to 1 nm via high-resolution online …

Classification Of Human Learning Stages Via Kernel Distribution Embeddings, Madeleine Shuhn-Tsuan Yuh, Kendric Ray Ortiz, Kylie Sue Sommer-Kohrt, Meeko Oishi, Neera Jain

School of Mechanical Engineering Faculty Publications

Adaptive automation, automation which is responsive to the human's performance via the alteration of control laws or level of assistance, is an important tool for training humans to attain new skills when operating dynamical systems. When coupled with cognitive feedback, adaptive automation has the potential to further facilitate human training, but requires precise assessments of human progression through various learning stages. This is challenging because of the underlying dynamics, as well as the stochasticity inherent to human action. We propose a data-driven approach to assess learning stages in a complex quadrotor landing task that is responsive to stochastic, human-in-the-loop quadrotor …

Granular Estimation Of User Cognitive Workload Using Multi-Modal Physiological Sensors, Jingkun Wang, Christopher Stevens, Winston Bennett, Denny Yu

Purdue University Libraries Open Access Publishing Fund

Mental workload (MWL) is a crucial area of study due to its significant influence on task performance and potential for significant operator error. However, measuring MWL presents challenges, as it is a multi-dimensional construct. Previous research on MWL models has focused on differentiating between two to three levels. Nonetheless, tasks can vary widely in their complexity, and little is known about how subtle variations in task difficulty influence workload indicators. To address this, we conducted an experiment inducing MWL in up to 5 levels, hypothesizing that our multi-modal metrics would be able to distinguish between each MWL stage. We measured …

Dieta De La Milpa: A Culturally-Concordant Plant-Based Dietary Pattern For Hispanic/Latine People With Chronic Kidney Disease, Annabel Biruete, Gabriela Leal-Escobar, Angeles Espinosa-Cuevas, Luis Mojica, Brandon M. Kistler

Purdue University Libraries Open Access Publishing Fund

Chronic kidney disease (CKD) disproportionately affects minorities in the United States, including the Hispanic/Latine population, and is a public health concern in Latin American countries. An emphasis on healthy dietary patterns, including the Mediterranean and the Dietary Approaches to Stop Hypertension (DASH) diets, has been suggested as they are associated with a lower incidence of CKD, slower CKD progression, and lower mortality in kidney failure. However, their applicability may be limited in people from Latin America. The Dieta de la Milpa (Diet of the Cornfield) was recently described as the dietary pattern of choice for people from Mesoamerica (Central Mexico …

Lai Mi Ka Si (I Am Lai Mi): A Poetry Collection, Thang C. Lian

Journal of Southeast Asian American Education and Advancement

In this poetry collection, I combine oral history with official Burmese history to trace my family’s diasporic journey from the mountains of Myanmar to Kentwood, Michigan in 2008. To do so, I conducted interviews with my mother, father, grandmother, and grandfather over Zoom and accumulated dozens of hours of material. A rumination on refugee grief and displacement, this creative work expresses and investigates the multi-layered ritual of grief refugees conduct internally and externally—an intentional and powerful foray into the “affective.” Finally, this creative work intends to sift through the complications of transnational grief: how, when, and why do we grieve?

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson

People and Animals: The International Journal of Research and Practice

As incidences of substance use disorders (SUD) increase in the wake of the COVID-19 pandemic, there is a need for more effective treatment approaches. Further, treatment approaches currently available struggle to retain patients during the period of substance withdrawal in early treatment due to patients’ withdrawal symptoms including increased feelings of anxiety and depression. Withdrawal symptoms have been linked to dysregulated cortisol concentrations present in this period. Psychotherapy incorporating equine interaction (PIE) has emerged in other populations as a treatment that decreases cortisol concentrations and improves treatment retention. The present study investigated the impact of 4 weeks of PIE on …

“Here, Kitty, Kitty.” Community Perceptions Of Free-Roaming Cats: A Northern Canadian Case Study, Annie Booth, Ken Otter

People and Animals: The International Journal of Research and Practice

Free-roaming domestic cats (Felis catus) create controversy, due to their tendency to invade neighbors’ gardens, hunt wildlife, and create disturbances. Municipal governments are often under pressure to address concerns regarding free-roaming cats. As approximately 28% of the 8.8 million cats owned in Canada free-roam (are allowed outside unsupervised and unconstrained), understanding owner rationales for letting the cat out is important for officials tasked with addressing public concerns. In 2019, we studied attitudes toward cats within a north-central British Columbia, Canada, city. The rationales cat owners use to justify free-roaming, as well as their perceptions about the risks and …

The aim of the CatSAAI questionnaire is to facilitate the interpretation of the behavioral suitability or unsuitability of each individual cat for inclusion in feline-assisted interventions, while considering the prevention of stress and risks in AAI settings for both people and animals. The tool was proposed by an …

Who Counts As Diverse? The Strategic Broadening And Narrowing Of Diversity, Junming Zhang, Teri A. Kirby

Purdue University Libraries Open Access Publishing Fund

Introduction: A large majority of US organizations profess a commitment to diversity, but their definitions of diversity can vary greatly. While previous research demonstrates a shift in diversity definitions to include fewer protected demographic groups and more non-demographic characteristics, the present research examines whether this shift might be a motivated process among dominant group members related to anti-egalitarian and colorblind belief systems.

Methods: Using quantitative and qualitative methods, we explored potential underlying ideologies that may be associated with White Americans’ shifting definitions of diversity. White Americans (N = 498) were asked how they define diversity, as well as who …
