Employing A Transitivity Violation Detection Algorithm To Assess Best–Worst Scaling Designs, Courtney Bir, Nicole Olynk Widmar, Natalya Slipchenko, Addison Polcyn, Christopher A. Wolf

Department of Agricultural Economics Faculty Publications

When choosing a partial factorial design for best–worst scaling (BWS) or other discrete choice experiment, researchers are faced with design size choices. This work investigates differences between two case 1 (object) BWS choice experiment designs that varied in choice set size and number of questions. Using a random-parameter logit model, preference shares were determined and statistically compared between models. The number of transitivity violations occurring between the experimental designs was analyzed employing a newly developed directed graph algorithm. The relative importance consumers placed on dairy milk attributes differed between the designs studied. The design presenting fewer attributes per choice set …

Destinations’ Recovery Marketing Campaigns In Response To Pandemics, Eli Avraham

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

The Covid-19 pandemic has altered the paradigm of risk and recovery management but it is just one of many pandemics to have impacted destinations during the last two decades. This study examine how destination officials combated the image crises that followed SARS-2003, H1N1 Swine flu 2009-10, Zika 2016-17 and Covid-19. The literature dealing with combating pandemics has focused on the actual management of either a specific pandemic or regional aspects of a pandemic and less on the recovery marketing and image repair aspect. As a result, tourism academic literature has a shortage of image repair theoretical frameworks addressing multi-case health-related …

Instagram Travel Influencers Coping With Covid-19 Travel Disruption, Andrei Kirilenko, Katarzyna Emin, Karen Tavares

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

A significant portion of today’s marketing is done through social media influencers, that is, through bloggers with established online credibility in a certain area who are recognized and followed by a sizable online audience. In the travel and hospitality industry, the influencer marketing is primarily done through Instagram due to its emphasis on visual images rather than texts. Covid-19 related travel restrictions and shrinking social media advertisement in travel industry have heavily impacted travel influencers, reducing their income and forcing many out of business. We present the outcomes of a study of the top 150 online travel influencers. The analysis …

Tourists’ Meaning Of Sustainability As A Tool For Segmentation. A Biosphere Reserve Case Study, Juan Ignacio Pulido-Fernández, Yaiza López-Sánchez, Isabel Carrillo-Hidalgo, Jose Luis Durán-Román

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

This paper provides empirical evidence on the potential use of the meaning of sustainability for the tourist in segmentation studies. The analysis has been applied to a nature destination, specifically, in the “Sierras de Cazorla, Segura y Las Villas” Biosphere Reserve. In the first place, this research identifies, through a cluster analysis, three segments of tourists based on what the tourist considers sustainability to be (level of knowledge and commitment, as well as its implications for the destination), analyzing for each segment their sociodemographic and socioeconomic variables and their willingness to pay to improve the sustainability of destinations.

The results …

Why Agriculture Productivity Falls: The Political Economy Of Agrarian Transition In Developing Countries, Rashed Al Mahmud Titumir

Purdue University Press Books

Why Agriculture Productivity Falls: The Political Economy of Agrarian Transition in Developing Countries offers a new explanation for the decline in agricultural productivity in developing countries. Transcending the conventional approaches to understanding productivity using agricultural inputs and factors of production, this work brings in the role of formal and informal institutions that govern transactions, property rights, and accumulation. This more robust methodology leads to a comprehensive, well-balanced lens to perceive agrarian transition in developing countries. It argues that the existing process of accumulation has resulted in nonsustainable agriculture because of market failures—the result of asymmetries of power, diseconomies of scale, …

The Combination Of Cooling Techniques In A Tropical Environment Improves Precision Performance In Young International Fencers, Aurélie Collado, Nicolas Robin, Stéphane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

The performance of intense exercise in a tropical climate is associated with limited exercise capacity due to thermal strain. This limitation is exacerbated in sports requiring full protective equipment. Research evidence suggests disturbances in cognitive function due to thermal discomfort and/or protective equipment (e.g., helmets), and thus sports that require skills in decision-making, fast reaction times, precision, and/or inhibition can be greatly affected. The objective of this study was to investigate the effects of countermeasures on the psychological and physiological responses in young international fencers wearing full protective equipment during an ecological fencing task. Nine young international fencers performed an …

Using An Approach-Avoidance Framework To Understand The Relationship Between Non-Lethal Weapons And Performance, Andrew J. Mojica, Christopher P. Bartak, Joseph N. Mitchell, Alan Ashworth

Journal of Human Performance in Extreme Environments

It is proposed that performance degradation from exposure to non-lethal technology is mediated by impulsive and reflective approachavoidance motivation. An approach-avoidance motivational framework was used to specify a four-stage information processing model that predicts performance degradation. The first stage is Evaluation: it processes physiological, sensory, perceptual, and cognitive information. The second stage is Comparison: it processes the content of the Evaluation into avoidance and approach motivational indices. The third stage is Probability: it processes information from previous stages into a probability of choosing to continue or abandon goal-directed behavior. Finally, the fourth stage is Performance: it processes performance accuracy on …

I’Ve Seen This, So I’Ve Got This! Exploring The Use Of Imagery And Self-Talk Within Action Sports Athletes, Patrick R. Young

Journal of Human Performance in Extreme Environments

The present study aimed to expand the current knowledge of psychological skills usage within athletes of action sports by exploring the use of imagery and self-talk within skateboarders and snowboarders. Skateboarders and snowboarders (N 5 74) completed the Athletic Coping Skills Inventory (ACSI-28; Smith et al., 1995), the Self-Talk Questionnaire (S-TQ) for sports (Zervas et al., 2007), and the Sport Imagery Questionnaire (SIQ; Hall et al., 1998). Results indicated that participants scored significantly higher than reported norms of traditional athletes (Smith et al., 1995) on the coping with adversity and goal-setting/mental preparation subscales of the ACSI-28, and to a similar …

Task-Driven Influences On Fixational Eye Movements, Jonathan Victor, Yen-Chu Lin, Michele Rucci

MODVIS Workshop

There is now compelling evidence that the spatiotemporal remapping carried out by fixational eye movements (FEMs) is an essential step in visual processing. Moreover, the overall Brownian-like statistics of FEMs are calibrated to map fine spatial detail into the temporal frequency range to which retinal circuitry is tuned. Here, we tested the hypothesis that the detailed spatial characteristics of FEMs can be adjusted to task demands via cognitive influences that operate even in the absence of a visual stimulus. We examined FEMs in a task that required subjects (N=6) to report which of two letters was displayed. Trials were blocked; …

How Object Segmentation And Perceptual Grouping Emerge In Noisy Variational Autoencoders, Ben Lonnqvist, Zhengqing Wu, Michael H. Herzog

MODVIS Workshop

Many animals and humans can recognize and segment objects from their backgrounds. Whether object segmentation is necessary for object recognition has long been a topic of debate. Deep neural networks (DNNs) excel at object recognition, but not at segmentation tasks - this has led to the belief that object recognition and segmentation are separate mechanisms in visual processing. Here, however, we show evidence that in variational autoencoders (VAEs), segmentation and faithful representation of data can be interlinked. VAEs are encoder-decoder models that learn to represent independent generative factors of the data as a distribution in a very small bottleneck layer; …

Constraining The Binding Problem Using Maps, Zhixian Han, Anne Sereno

MODVIS Workshop

We constrained the binding problem by creating maps of different attributes. We compared the performance of different models with different maps in our current study. Our preliminary results showed that the performance of the model is the highest when location maps were used. These results suggest that the optimal way to constrain the binding problem is to create location maps of different attributes.

Leveraging Mathematical Modeling To Analyze Nonadherence For Hydroxyurea Therapy In Sickle Cell Disease, Akancha Pandey, Rubesh Raja, Jeremie H. Estepp, Doraiswami Ramkrishna

Purdue University Libraries Open Access Publishing Fund

Nonadherence is common in individuals with sickle cell disease (SCD) on hydroxyurea therapy and can be observed with waning improvements in hematologic parameters or biomarkers like mean cell volume and fetal hemoglobin level over time. We modeled the impact of hydroxyurea nonadherence on longitudinal biomarker profiles. We estimated the potential nonadherent days in individuals exhibiting a drop in biomarker levels by modifying the dosing profile using a probabilistic approach. Incorporating additional nonadherence using our approach besides existing ones in the dosing profile improves the model fits. We also studied how different patterns in adherence give rise to various physiological profiles …

Sow Temperature Probe Design, Javier Flores

American Journal of Rising Scholar Activities

With temperatures increasing steadily throughout the last century, the swine production industry is beginning to confront an increasingly urgent dilemma. Ambient barn temperatures are now regularly exceeding ideal conditions for optimal milk production, as well as maximum litter size. Temperatures that exceed these conditions can lead to heat stress among sows, which can ultimately lead to death. With sows usually being housed in larger group settings, keeping track of an individual sow’s temperature has never been harder. The focus of this project is efficiently tracking the internal vaginal temperature of a sow. A prototype probe was developed and consists of …

The Future Of Mobility-As-A-Service: Trust Transfer Across Automated Mobilities, From Road To Sidewalk, Jacob G.

Kumar, Kumar Akash, Teruhisa Misu, Neera Jain, Tahira Reid

School of Mechanical Engineering Faculty Publications

While trust in different types of automated vehicles has been a major focus for researchers and vehicle manufacturers, few studies have explored how people trust automated vehicles that are not cars, nor how their trust may transfer across different mobilities enabled with automation. To address this objective, a dual mobility study was designed to measure how trust in an automated vehicle with a familiar form factor—a car—compares to, and influences, trust in a novel automated vehicle—termed sidewalk mobility. A mixed-method approach involving both surveys and a semi-structured interview was used to characterize trust in these automated mobilities. Results found that …

Critical Nematic Correlations Throughout The Superconducting Doping Range In Bi2−Zpbzsr2−Ylaycuo6+X, Can-Li Song, Elizabeth J. Main, Forrest Simmons, Shuo Liu, Benjamin Phillabaum, Karin A. Dahmen, Eric W. Hudson, Jennifer E. Hoffman, Erica W. Carlson

Purdue University Libraries Open Access Publishing Fund

Charge modulations have been widely observed in cuprates, suggesting their centrality for understanding the high-Tc superconductivity in these materials. However, the dimensionality of these modulations remains controversial, including whether their wavevector is unidirectional or bidirectional, and also whether they extend seamlessly from the surface of the material into the bulk. Material disorder presents severe challenges to understanding the charge modulations through bulk scattering techniques. We use a local technique, scanning tunneling microscopy, to image the static charge modulations on Bi2−zPbzSr2−yLayCuO6+x. The ratio of the phase correlation length ξ …

Don’T “Just Google It”: Deweyan Perspectives On Participatory Learning With Online Tools, Eric Thomas Weber, Heather Cowherd, Mia Morales

Education and Culture

John Dewey argued that for education to be democratic, it is important for students to be not merely spectators but also participants in learning. Teachers sometimes find personal computing devices to be distracting or to contribute to passivity rather than activity in the classroom. In this essay we examine the question of whether a student’s Google search on a subject matter discussed in class is participatory or passive. We argue that with proper guidance students’ use of online searches and related tools can empower students democratically as sources of ideas, conceptualizations, information, and insight while emphasizing participation in deliberation and …

Challenges In Education: A Deweyan Assessment Of Ai Technologies In The Classroom, Ande Eitner

Education and Culture

Artificial intelligence is profoundly transforming the world in various spheres and already finding its way into educational institutions. This essay aims to examine whether the Deweyan ideal of education can be achieved through such digital means. By analyzing how both the aims and means of education, as defined by Dewey, can be understood in the context of learning with artificial intelligence, the inherent differences of both educational approaches are brought out. It becomes apparent that important concepts that characterize successful education for Dewey, such as intrinsic inquiry, experience-based schooling, and thinking as the method for learning, do not go hand …

Data And Growth In Education: A Deweyan Analysis, Kevin Taylor

Education and Culture

For Dewey, growth in the educative process means education that enriches and expands one’s experience as it prepares students for not only a vocation but also entry into and transaction with the world. In few places can we see growth, generally understood, to be occurring as fast as in big data technology. This essay begins with an overview of what big data is, specifically what big data looks like in education as understood through learning management system platforms but also data as understood generally on a college campus through dataveillance, or data surveillance understood as the monitoring or possibility of …

Reviews Of The Shared Room And The Most Beautiful Thing, Bao Diep

Journal of Southeast Asian American Education and Advancement

Grief and Loss are often seen as taboo subjects to discuss openly in many cultures. However, grief is universal, perpetual, and complex. Grief can take many forms and depend on the nature of the attachment between the survivor and the dead (people, animals, living things). When Loss happens, the survivor’s attachment will influence the shape and level of grief. Kao Kalia Yang (2020) has brought the topic of attachment, grief and loss to her children’s books, The Shared Room and The Most Beautiful Things, to initiate this difficult conversation.

Method For Estimating Pulsatile Wall Shear Stress From One-Dimensional Velocity Waveforms, Joseph C. Muskat, Charles F. Babbs, Craig J. Goergen, Vitaliy L. Rayz

Purdue University Libraries Open Access Publishing Fund

Wall shear stress (WSS)—a key regulator of endothelial function—is commonly estimated in vivo using simplified mathematical models based on Poiseuille's flow, assuming a quasi-steady parabolic velocity distribution, despite evidence that more rapidly time-varying, pulsatile blood flow during each cardiac cycle modulates flow-mediated dilation (FMD) in large arteries of healthy subjects. More exact and accurate models based on the well-established Womersley solution for rapidly changing blood flow have not been adopted clinically, potentially because the Womersley solution relies on the local pressure gradient, which is difficult to measure non-invasively. We have developed an open-source method for automatic reconstruction of unsteady, Womersley-derived …

Chile Pepper Variety Evaluation And Profitability Analysis At Three Farms In Minnesota And Wisconsin, 2022, Natalie Hoidal, Charlie Rohwer, Ryan Pesch, Rodrigo Cala, Javier García, Griselda Bernabe Suarez, Fernando Alejandro García Loyo

Midwest Vegetable Trial Reports

Latino fresh market vegetable farmers in Minnesota and Wisconsin are interested in growing hot peppers for local markets, both for fresh and dried pepper sales. This variety trial is the third and final trial of a 3 year project. We trialed 14 varieties of peppers representing jalapeño, serrano, habanero, poblano, and “other” types. The varieties included the top varieties from 2020 and 2021, alongside new varieties. We measured yield, fruit size, and Scoville heat units. In addition to the variety trial, we conducted an enterprise analysis to determine the profitability of hot pepper production in the Upper Midwest.
