Opening A Dialogue Between Translanguaging And Interlectal Practices: Constrained Freelanguaging For Peaceful Language Education, Christian Ollivier, Logambal Souprayen-Cavery Mar 2026

Opening A Dialogue Between Translanguaging And Interlectal Practices: Constrained Freelanguaging For Peaceful Language Education, Christian Ollivier, Logambal Souprayen-Cavery

Dimensions

Translanguaging concepts and practices have gained great attention across the globe, at risk of overshadowing and obscuring the contributions of research and theories from non-Anglophone areas. For example, research from the Francophone world that has long investigated interlectal practices, a form of translingual practice in Creole-speaking areas, yet remains lesser known. This theoretical paper aims to initiate a dialogue between less-known peripheral studies about interlectal practices and the omnipresent North American translanguaging approach. Specifically, this paper presents the concepts and linguistic dimensions of translanguaging and interlectal practices as defined in the literature, highlighting similarities and differences in the ways of …

To Swear Or Not To Swear: Exploring The Role Of Profanity In Influencer Marketing, Mahdi Niknejad Moghadam, Vijay Mahajan

Marketing Faculty Publications and Presentations

Influencers play a central role in promoting products and services on digital platforms. Understanding the impact of their linguistic choices, including the use of profanity, is therefore important for marketers seeking to engage target audiences. This study investigates how influencers’ profanity usage shapes user engagement. The authors analyze videos shared by influencers on a popular video-sharing platform and extract auditory, visual, and verbal features using a range of machinelearning tools. The findings indicate that profanity in focal content is associated with lower engagement, with a substantially larger effect in categories where profanity is less normatively expected. This negative effect is …


Spatial Variability Of Nitrates And Nitrogen Mineralization Kinetics And Their Effects In Long-Term Tillage Systems, Bibash Rokaya Mar 2026

Spatial Variability Of Nitrates And Nitrogen Mineralization Kinetics And Their Effects In Long-Term Tillage Systems, Bibash Rokaya

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Nitrogen (N) and water management are essential for water quality protection and crop production. However, soil N and water are spatiotemporally variable. Soil water spatial dependencies are described in the literature with known associations with preferential flows among other factors. In contrast, a knowledge gap exists on the spatial dependence of soil N mineralization kinetics. We hypothesize that soil N mineralization kinetics and soil water have distinct and cross-correlated spatial characteristics among soil management practices and climatic regions. For the field study, we measured soil-N mineralization kinetics, volumetric water content (VWC), and a suite of soil properties along ~70 m …


Law And The Self-Coordinating Market Idea, Sanjukta Paul Mar 2026

Law And The Self-Coordinating Market Idea, Sanjukta Paul

University of Chicago Law Review

“This emotional pronouncement of value judgments condemning emotion and value judgments seems to [me] a symptom of a defective sense of humor. The attempt to build a social science on these foundations suggests that the human race, and especially a large proportion of its ‘best minds,’ having at long last (a very long last) found out that the objects of nature are not like human beings—are not actuated by love and hate and caprice and contrariness, and subject to persuasion, cajolery, and threats—have logically inferred that human beings must be like natural objects, and so viewed by the seeker of …

Comprehensively Evaluating The Perception Systems Of Autonomous Vehicles Against Hazards, Xiaodong Zhang, Jie Bao, Jianlei Chi, Jun Sun, Zijiang Yang

Research Collection School Of Computing and Information Systems

Perception systems are vital for the safety of autonomous driving. In complex autonomous driving scenarios, autonomous vehicles must overcome various natural hazards, such as heavy rain or raindrops on the camera lens. Therefore, it is essential to conduct comprehensive testing of the perception systems in autonomous vehicles against these hazards, as demanded by the regulatory agencies of many countries for human drivers. Since there are many hazard scenarios, each of which has multiple configurable parameters, the challenges are (1) how do we systematically and adequately test an autonomous vehicle against these hazard scenarios, with measurable outcome; and (2) how do …

Evaluating How Public Land Managers Use General Visitor Survey Data For Decision-Making, Kayla E. Wernsing Mar 2026

Evaluating How Public Land Managers Use General Visitor Survey Data For Decision-Making, Kayla E. Wernsing

All Theses

Using data to inform decisions about policy, staffing, resource management, and infrastructure is widely regarded as a best practice among public land managers. A substantial body of empirical research has examined frameworks for data-informed decision-making on public lands, as well as factors that support or hinder its implementation. However, relatively little attention has been given to how managers use general visitor survey data to make site-specific decisions. This study explored how managers in one U.S. federal agency use data from a general visitor survey specific to their site, or, if they are not, what barriers are preventing application. Researchers conducted …

Applying Direct Numerical Simulations To Investigate Wave Forcing Against A Vertical Wall, Hunter Boswell, Frank D. Han, Gaurav Savant, Guirong Yan, Wouter Mostert

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Current engineering standards lack the ability to predict the peak impact forces of breaking waves impinging directly upon coastal structures. In this study solitary waves impacting vertical and tapered walls are investigated. To capture the detailed physics of the wave profile that impacts the wall, two-dimensional direct numerical simulations are applied to model the wave traveling over a simplified bathymetry consisting of an initially uniform depth, followed by a uniform beach ramp and then terminating in a uniform depth inshore region and vertical wall. Such an approach can simulate wave runup on land and then the impact with the vertical …

Evidence And Assessing Verbatim Transcription Quality Of Black English And Standard American English, L. Alexander Walker Iii

Faculty Scholarship

This chapter explores the accuracy of private transcription services when transcribing Black English and Standard American English. Courts and lawyers in the US regularly rely on transcripts from such services, but third-party verification of their accuracy, especially with respect to their quality when faced with nonstandard language varieties, is lacking. This study draws on experimental methods to contrast the quality of transcription services offered by transcribers and AI route. The quantitative results show that transcription by humans and AI resulted in more mistakes when transcribing Black English than when transcribing Standard American English. Furthermore, a qualitative analysis reveals that these …

Psychological Science Faculty Research & Creative Works

How do robot designers anthropomorphize their own creations? Because robot designers have the ability to alter the robot, identify as its creator, and understand their robot's internal makeup, their process of anthropomorphism and its outcomes may be different from that of the typical robot user. We investigate this research question in the domain of combat robots, where anthropomorphism is critical to decision-making, communication, and trust in high-stakes, high-emotion combat situations faced by robot-soldier teams. We conducted an in-depth case study of a university's student-led Combat Robotics Design Team over the design, construction, testing, and competition phases for their competitive combat …

This study examines human arm kinematics during overground physical human-robot interaction (pHRI). Previous work showed humans adjust arm stiffness with changing trajectory uncertainty, but the roles of arm kinematics and muscle activation remained unclear. Building on a preliminary study, we analyzed arm movements with more participants (10 individuals) to achieve more reliable findings and examined two potential influences that arose in the preliminary study: the robot's perturbation effect (a brief hand push) and left-to-right trunk sway. Using a linear mixed-effects model, we evaluated the effects of participant, block, and trajectory condition on arm angles. Results showed minimal kinematic contribution to …

Microstructural Evolution Of Zirconium Diboride Irradiated With 5–10 Mev Au Ions At Room Temperature And 570 °C, Narrie Loftus, José Olivares, Miguel Crespillo, Esther Enríquez Pérez, Jeremy Watts, Eric W. Bohannan, Gregory Hilmas, William Fahrenholtz, Joseph Graham

Materials Science and Engineering Faculty Research & Creative Works

Zirconium diboride was irradiated with 5 MeV Au2 + , 7 MeV Au4+ and 10 MeV Au3+ ions at room temperature and 570 °C to doses from 1 to 8 displacements per atom (dpa). Grazing incidence X-ray diffraction (GIXRD) analysis revealed no secondary phase formation. Rietveld analysis of the GIXRD data indicated an accumulation of microstrain at low dpa and room temperature. Dislocations observed in transmission electron microscopy (TEM) cross-sections are likely the main contributor to the microstrain. High dpa and high-temperature samples exhibit lower lattice distortion than lower dpa samples, suggesting the presence of enhanced defect …

Positive Youth Development And Connection With Nature Through Urban Agriculture, Casey Ortbahn, Marijke Hecht, Kristi Lekies

Journal of Youth Development

Youth urban agriculture programs connect youth with nature and support positive youth development. In this qualitative study, we use photovoice to amplify youth voices and explore 16 high school youths’ perceptions of how participation in a youth gardening program supported their confidence, connection, and sense of belonging. Using qualitative thematic analysis of photos, posters, and interviews, we identify several program processes that supported confidence and belonging, including meaningful relationships with peers and adults, connections with nature, and relationships with more-than-human beings. Our analysis reveals that nature is an important context for youth development and that nature is also more than …

Nominal Prices, Retail Investor Participation, And Return Momentum, Jun Du, Dashan Huang, Yu-Jane Liu, Yushui Shi, Avanidhar Subrahmanyam, Huacheng Zhang

Research Collection Lee Kong Chian School Of Business

We employ an identification strategy for retail participation to explore the link between return momentum and investing clientele. This scheme relies on strictly enforced round-lot rules in China, which financially constrain retail investors from participating in stocks with high nominal prices. We find that there is strong momentum in high-priced stocks, but no momentum on aggregate. This result supports the idea that noise trades of retail investors mask momentum, while other, more sophisticated investors contribute to momentum. We validate this notion by showing that retail investors with small (large) portfolios are less (more) prone to participating in stocks with high …

Data-Driven Non-Precipitation Echo Removal Of Nexrad Radars Based On A Random Forest Classifier Using Polarimetric Observations And Goes-16 Data, Munsung Keem, Bong Chul Seo, Witold F. Krajewski, Sangdan Kim

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Highlights: What are the main findings? A Random Forest-based model using dual-polarimetric radar features achieves >99% accuracy in classifying precipitation and non-precipitation echoes. Multi-scale spatial variability features enhance discrimination between genuine precipitation and spurious echoes. Fusion of GOES-16 infrared satellite data with NEXRAD radar effectively removes non-precipitation echoes with precipitation-like signatures, including wind turbine clutter. A CAPPI scan strategy improves near-radar precipitation detection by recovering valid echoes misclassified at the lowest elevation due to side-lobe interference and limited sampling volume. What are the implications of the main findings? The model's robustness to noise and overfitting, combined with minimal hyperparameter tuning, …
