Department of Speech, Language, and Hearing Sciences Faculty Publications

Purpose: Providing culturally responsive care for a diverse patient population is critical for future speech-language pathologists and audiologists. Prior studies have shown gains in intercultural competence (ICC) from study abroad programs, face-to-face classes, and online courses; however, limited studies have investigated differences between face-to-face and online modes of delivery in speech-language pathology and audiology. The purpose of this study was (a) to evaluate whether there are quantitative differences in development of ICC in a direct comparison of a face-to-face and 100% asynchronous online introductory in communication dis-orders, and (b) to describe participants learning through the structural intercultural learning activities embedded …

Development Of Protocols For Reuse Assessment Of Existing Foundations In Bridge Rehabilitation And Replacement Projects, Jeehee Lim, Rodrigo Salgado, Monica Prezzi, Yao Wang, Fei Han

JTRP Technical Reports

The existing foundations of a bridge can sometimes be reused. This may occur when a completely new bridge is built but also in bridge or superstructure widening projects. Reuse of existing foundations not only eliminates the costs associated with demolishing and disposing of old foundations, but also reduces the costs of the design and construction of new foundation elements. However, several challenges exist, including assessing the structural integrity, estimating the current capacity, estimating the remaining service life, and considering current design codes and specifications of the existing foundations, and clear guidelines for foundation reuse. The absence of foundation reuse guidelines …

Bim Standards For Roads And Related Transportation Assets, Hang Li, Hosam Hegazy, Xiaorui Xue, Jiansong Zhang, Yunfeng Chen

JTRP Technical Reports

With the industry foundation classes (IFC) building information modeling (BIM) standard (ISO 16739) being adopted by AASHTO as the national standard for modeling bridge and road infrastructure projects, there comes a great opportunity to upgrade the INDOT model development standard of roads and related assets to 2D+3D BIM. This upgrade complies with the national standard and creates a solid foundation for preserving accurate asset information for lifecycle data needs. This study reviewed the current modeling standards for drainage and pavement at different state DOTs and investigated the interoperability between state-of-the-art design modeling software and IFC. It was found that while …

Contingency As A Barrier To Decolonial Engagement: Listening To Multilingual Writers, Grace Lee-Amuzie

The Writing Center Journal

Based on the concept of transformative listening by García (2017) that views listening as a form of decolonial work that must take place in writing centers, the article examines colonial thinking and contingency as toxic preexisting conditions of writing center ecology that hinder our ability to listen to marginalized multilingual voices. Recognizing the commonality between multilingualism and contingency, both as ignored marginalized intersecting identities in the hierarchy of the racialized and corporatized university system, the article describes the complexity of engaging contingent workers in decolonial work and listening. Further, it argues that contingency creates significant barriers to the type of …

Spatiotemporal Distribution Change Of Online Reference During The Time Of Covid-19, Thom Gerrish, Ningning Nicole Kong

A Model For Equity-Oriented Prek-12 Engineering, Christine M. Cunningham, Gregory J. Kelly

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

In this paper, we address the societally important issue of developing a more equitable approach to preK-12 engineering education. Our primary emphasis is on K-8 grades—a time when first impressions of engineering may be developed. Calls for increased participation by all students, including those who have been historically marginalized, motivate the need for theoretically grounded ways of developing and assessing educational programs. This paper draws from sociocultural learning theory and applies four theoretical and empirical analyses to derive design principles for equity that can inform curriculum, instruction, and assessment of preK-12 engineering education programs. We present a model for equity-oriented …

A New Gtseq Resource To Facilitate Multijurisdictional Research And Management Of Walleye Sander Vitreus, Peter T. Euclide, Wesley A. Larson, Matthew Bootsma, Loren M. Miller, Kim T. Scribner, Wendylee Stott, Chris C. Wilson, Emily K. Latch

Purdue University Libraries Open Access Publishing Fund

Conservation and management professionals often work across jurisdictional boundaries to identify broad ecological patterns. These collaborations help to protect populations whose distributions span political borders. One common limitation to multijurisdictional collaboration is consistency in data recording and reporting. This limitation can impact genetic research, which relies on data about specific markers in an organism's genome. Incomplete overlap of markers between separate studies can prevent direct comparisons of results. Standardized marker panels can reduce the impact of this issue and provide a common starting place for new research. Genotyping-in-thousands (GTSeq) is one approach used to create standardized marker panels for nonmodel …

Gait Phase Estimation Of Unsupervised Outdoors Walking Using Imus And A Linear Regression Model, Ahmed Soliman, Guilherme A. Ribeiro, Andres Torres, Li-Fan Wu, Mo Rastgaar

Purdue University Libraries Open Access Publishing Fund

Human gait analysis and detection are critical for many applications, including wearable and rehabilitation robotic devices, reducing or tracking injury risk. The proposed work allows researchers to study the gait phase of human subjects in an unsupervised outdoor environment without the need for fixed thresholds and sensor-embedded insoles. We present an experimental protocol to label gait events based on patterns in human subjects from two body-worn inertial measurement units (IMUs). Gait patterns are developed using a force plate and a motion capture system. Upon defining the gait pattern, human subjects walk outdoors for forty minutes to train and test a …

The Price Of Longevity - Empirical Evidence From Road Pavements, Hanna Kemaw

Lyles School of Civil Engineering Graduate Student Reports

The vast network of county, city and town roads, represent a big part of public assets in most states and often account for a significant share of the public spending on roads. This spending on local road infrastructure help to build, operate, and preserve such infrastructure and therefore provide critical accessibility and mobility to the residents of counties, towns and cities. With the ever-growing volumes of personal and commercial traffic at local roads, the task of maintaining satisfactory levels of service at local roads has become more challenging, and this issue is exacerbated by limited resources, asset aging, and increasing …

Identifying Dis/Misinformation On Social Media: A Policy Report For The Diplomacy Lab Strategies For Identifying Mis/Disinformation Project, Bethany S. Mcgowan, Matthew Hannah, Sofia Babcock, Katelyn Biggs, Lara Chuppe, Christina Galiatsatos, Jannine Huby, Michael Kuczajda, Bennet Miller, Stephanie Perun, Amanda Shie, Alicia Stevance, Andrew Yason, Charlotte Yeung

Libraries Faculty and Staff Scholarship and Research

Dis/misinformation was a major concern in the 2016 U.S. presidential election and has only worsened in recent years. Even though domestic actors often spread dis/misinformation, actors abroad can use it to spread confusion and push their agenda to the detriment of American citizens. Even though this report focuses on actors outside the United States, the methods they use are universal and can be adapted to work against domestic agents. A solid understanding of these methods is the first step in combating foreign dis/misinformation campaigns and creating a new information literacy paradigm.

This report highlights the primary mechanisms of dis/misinformation: multimedia …

Myocardial Strain Imaging In Duchenne Muscular Dystrophy, Conner C. Earl, Jonathan Soslow, Larry W. Markham, Craig J. Goergen

Purdue University Libraries Open Access Publishing Fund

Cardiomyopathy (CM) is the leading cause of death for individuals with Duchenne muscular dystrophy (DMD). While DMD CM progresses rapidly and fatally for some in teenage years, others can live relatively symptom-free into their thirties or forties. Because CM progression is variable, there is a critical need for biomarkers to detect early onset and rapid progression. Despite recent advances in imaging and analysis, there are still no reliable methods to detect the onset or progression rate of DMD CM. Cardiac strain imaging is a promising technique that has proven valuable in DMD CM assessment, though much more work has been …

An Imaginary* Interview With A Philippines Collections Museum Donor, Camille Ungco

Journal of Southeast Asian American Education and Advancement

Ontological distance is the dehumanization that emerges from uninterrogated coloniality between colonized subjects and the oppressive systems. This distancing has occurred in the histories of U.S. teachers both domestic-based and abroad, especially in Southeast Asia. In Steinbock-Pratt’s (2019) historiography on the relationships between early 1900s U.S. teachers and their Filipinx students, ontological distance was “The crux of the colonial relationship was intimacy marked by closeness without understanding, suasion backed by violence, and affection bounded by white and American supremacy” (Steinbock-Pratt, 2019, p. 214). This dehumanizing psychological or ontological distance existed during U.S. colonial regimes abroad, specifically in Southeast Asia and …

Print3d, A Service-Learning Project For Improving Visually Impaired Accessibility Through Educational 3d Printing, Oscar R. Lozano

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

Well-executed service-learning projects are a high-value educational element. However, these projects commonly focus on overused topics and unbalanced executions which can produce the opposite effect to that desired when working with groups of people with functional diversity. PRINT3D is a service-learning project aimed at improving accessibility for people with visual disabilities while helping primary and secondary school students learn basic engineering skills through 3D design and printing. Under the support of the European Erasmus+ Programme, this project brought together nongovernmental organizations, teacher professional development centers, business enterprises, and educational centers to collaborate for two school years.

Translanguaging Views And Practices Of Indiana Dual-Language Bilingual Education Teachers, Amanda Shie

The Journal of Purdue Undergraduate Research

As of fall 2018, the United States had 5 million English language learners (ELLs) in the public K–12 education system (National Center for Education Statistics, 2021). Within this population, ELL students in Indiana number over 50,000, or 5.9% of all public K–12 students in the state. Dual-language bilingual education (DLBE) programs often neglect the strategy of translanguaging in the classroom, disadvantaging ELLs. Translanguaging is defined as drawing “on all the linguistic resources of the child to maximize understanding and achievement” and is demonstrated in the natural switching of languages in bilinguals (Lewis et al., 2012). Further, translanguaging attempts to correct …

People and Animals: The International Journal of Research and Practice

Over recent decades, the use of animal-assisted interventions (AAIs) in educational settings has attracted growing international interest both among educators and the research community. However, there has been little comparative analysis of the demographics of participants and the rationale behind such practices. The aim of this paper is to address this. An anonymous online questionnaire was distributed via social media and other networks. Quanti-tative and qualitative data were collected from 610 participants across 23 countries, mostly from the United Kingdom and North America. In total, 315 (51.6%) participants reported involving animals in their settings. The results show that although animals …

Pisum Sativum Has No Competitive Responses To Neighbors: A Case Study In (Non)Reproducible Plant Biology, Mariah L. Mobley, Audrey S. Kruse, Gordon G. Mcnickle

Purdue University Libraries Open Access Publishing Fund

Plant–plant competition is ubiquitous in nature. However, studying below ground behavior of roots has always posed certain difficulties. Pea (Pisum sativum L.) has become a common study species for questions about how plant roots respond to neighboring plant roots and barriers in soil. However, published results point in several different directions. This has sometimes been interpreted as pea having sophisticated context dependent responses that can change in complex ways depending on its surroundings, but it could also just point to small statistical power resulting in type I or II statistical errors. To explore this further, here, we combine the result …

The Communicative And Affective Labor Of Public Pandemic Diaries: The Case Of Fang Fang’S Wuhan Diary, Chen Chen

Journal of Rhetoric, Professional Communication, and Globalization

This article studies the immaterial labor of Fang Fang’s Wuhan diary about the Wuhan COVID-19 lockdown time period, Jan 23 to Apr 8, 2020 (her diary ran from Jan 25 to Mar 24). Guided by social justice-informed, critically contextualized methodology, this analysis examines how the rhetoric of Fang Fang’s diary as tactical communication contributed to enacting social justice during the Wuhan lockdown by recognizing, revealing and rejecting oppressions people experienced both due to the challenges of the pandemic outbreak and the government’s inadequate and problematic responses. In doing so, Fang Fang uses her own positionality and privilege to challenge problematic …
