Facilitating Quality Feedback Practices for Teacher Educators: An Action Research Study

The student teaching practicum is widely considered the most important experience for pre-service teachers, providing a key opportunity for high-quality feedback to support instructional growth. Cooperating teachers and university supervisors (faculty responsible for observing an...

Predicting Competitive Bidding Levels in Transportation Projects Using Explainable Machine Learning and Deep Learning Methods

Abstract Maintaining robust competition in transportation construction bidding is challenging for State Departments of Transportation (DOTs) as they navigate fluctuating input prices, complex project scopes, and variable market conditions. Existing approaches to forecasting bidde...

Influence of Color-Center Electronegativity on Circular Dichroism in Single-Walled Carbon Nanotubes

Abstract Covalently functionalized single-walled carbon nanotubes (SWCNTs) have emerged as attractive quantum photonic materials due to their highly tunable optical properties and efficient single-photon emission capabilities. Recent progress in engineering chiral defects has mot...

Temporal separation of meanings facilitates homophone learning

Theories of word learning often assume that learners adhere to a one-to-one form-to-meaning mapping hypothesis, reducing the number of possible meanings for newly encountered words and permitting learners to assume that known words correspond to their known referents. However, al...

Genomic Regions Associated with Resistance to Soybean Cyst Nematode ( Heterodera glycines Ichinohe) Population HG Type 1.2.5.7 in Dry Beans ( Phaseolus vulgaris L.)

Ichinohe, 1952). Host resistance is an effective management strategy, yet resistance to the virulent SCN population HG type 1.2.5.7 has not been genetically characterized in dry beans. In this study, 170 dry bean genotypes (113 breeding lines/cultivars and 57 germplasm accessions...

Who Do You Trust? Demographic Patterns in Vaccine Hesitancy among Older Adults in a Rural State

Older adults are at increased risk for complications from vaccine-preventable diseases, yet many remain undervaccinated. This study examined demographic variability in vaccination hesitancy among older adults in a rural state and the potentially mediating role of trust uncertaint...

PREDICTING HEART DISEASE RISK FROM CLINICAL VARIABLES: A GENDER-SPECIFIC MACHINE LEARNING ANALYSIS AMONG HIGH-CHOLESTEROL PATIENTS

Cardiovascular disease remains a major cause of mortality and economic burden in the United States. This study developed and evaluated supervised machine learning models to predict heart disease risk from routine clinical variables and tested whether male patients with high chole...

Academic mobility and identity in transition: comparative insights from multilingual scholars across higher educational systems

Purpose This paper aims to examine how bi- and multilingual academics reconstruct professional identities during international mobility and how they exercise agency in relation to language hierarchies, institutional expectations, and belonging across higher education systems. Des...

Evolution of Bed Shear Stress in Open-Channel Flow at Smooth-to-Rough and Rough-to-Smooth Transitions

Abstract The evolution of bed shear stress in open-channel flows due to a sudden change in bed roughness was investigated for rough-to-smooth (RTS) and smooth-to-rough (STR) transitions. The velocity field was measured in the longitudinal–vertical plane at high spatial resolution...

Detection of False Stealthy Data Injection Attacks in Smart Meters Using Machine Learning and Blockchain Technology

Despite the benefits associated with the use of smart meters in advanced metering infrastructure, the widespread deployment of such meters has introduced vulnerabilities that leave power systems susceptible to stealthy false data injection attacks which cannot be detected by conv...

Surface-LimitedChemical and Physical Alteration ofPlastics during Composting: An In-Depth Field- and Lab-Scale Study

Abstract Plastics entering composting systems are frequently found as fragments in finished compost, yet the mechanisms controlling their degradation and persistence remain unclear. In this study, food waste amended with virgin, 30-day UV-weathered, and 30-day sunlight-weathered...

First-principles identification of optically efficient erbium centers in GaAs

Gallium arsenide (GaAs) doped with erbium (Er), a material of interest for optoelectronics and quantum information, has been studied for decades. Yet the formation of Er luminescence centers in the semiconductor host and their properties are still not well understood. Here we pre...
