Headwater Dynamics: Quantifying Spatial Differences in Flow Permanence and Network Connectivity across Diverse Landscapes

Creator:: Pate, Adam A.
Abstract:: Forested headwater streams are critical for the supply of water, sediment, nutrients, and organic matter to downstream water bodies. Nearly half of all headwater streams display temporary flow regimes (i.e., non-perennial), but with climate change they may become more common. Thus, it will be increasingly imperative to adequately represent non-perennial...

The current experiment examined whether metacognition—the ability to assess self-performance—and numeracy—the ability to understand and work with numbers—predict the efficiency of automation use in a signal detection task. Two-hundred twenty-one participants classified random dot...

Collaborative Metacognition and Decision Making in a Signal Detection Task

Creator:: Duncan-Reid, Jackson
Abstract:: When decision makers work collaboratively, their combined performance can exceed the performance of even the best group member working alone. However, despite the potential for performance gains when working in a group, collaborating individuals often show poor coordination and losses of motivation, and are generally inefficient at combining their resources...

Not Good Enough: Ironic Efficiency in Automated-Aided Signal-Detection

Creator:: Munoz Gomez Andrade, Fernando
Abstract:: During applied signal-detection (e.g., airport-baggage screening) human operators can be assisted in their decision-making process by automated devices. Automation implementation is aimed at increasing performance relative to unaided levels. Generally, this intended effect is empirically observed. However, operators consistently fall short of optimal levels of aided performance, indicating suboptimal aid-use...

A Comparison of Formation Factor to Standard Methods to Evaluate Transport Properties

Creator:: Whatley, Samantha N.
Abstract:: Chloride-induced corrosion is one of the primary causes of the degradation of reinforced steel in concrete structures. Currently, the rapid chloride permeability test (RCPT) is the most specified method to determine the concrete’s resistivity to chloride ingress, thus a determining factor in assessing the durability of concrete. While it is...

Analyzing the Effects of Psychosocial Determinants on Health Outcomes of Older Adults with Multimorbidity

Creator:: Pai, Nidhi S.
Abstract:: Multimorbidity, or the concurrent presence of two or more chronic conditions, significantly increases the risk of adverse health outcomes, particularly for adults age 65 and older. Psychosocial, behavioral and social factors can further exacerbate the impact of multimorbidity, but are infrequently and inconsistently documented within electronic health records (EHRs).
