Factors Affecting Severity Level in Speed-Related Crashes and in Identification of Crashes Involving Exceeding Maximum Safe Travel Speed
This research investigates factors that influence severity of speed-related crashes on mainline roadway segments, with a particular emphasis on comparing single-vehicle and multiple-vehicle incidents and distinguishing between crashes involving legal speed limit violations and those exceeding the …

Understanding Fixed Object Crashes with SHRP2 Naturalistic Driving Study Data
… employed for two responses: crash occurrence and severity level. Logistic regression analyses identified 16 and 10 significant variables with significance levels of 0.1, relevant to driver, roadway, environment, etc. for two responses respectively. The logistic regression analyses led to a series …

Optimal speed limit for shared-use roadways
… speed limit, crash frequency, and crash injury severity. A comprehensive literature review about the relationship among posted speed limit, crash frequency, and crash injury severity level was conducted. Crash frequency prediction models and crash injury severity models are developed to obtain …

Predictors of Posttraumatic Stress Disorder in Chronic Low Back Pain Patients
… of posttraumatic stress disorder (PTSD) symptom severity level in patients with chronic low back pain (CLBP). Research questions focused on whether or not patients with CLBP would evidence clinically-significant levels of PTSD, whether or not the intensity and duration of the trauma would predict …

Automated Assessment of Psychiatric Patients Using Medical Notes
… require continuous monitoring on par with their severity status. Unfortunately, current assessment instruments are often time-consuming. The present thesis introduces several passive digital markers (PDMs) that can help reduce this burden by automating the assessment using medical notes. The …

Growing up with autism: Experiences of adult siblings
… well as psychiatric diagnoses than TD-sibs. The severity level of autism was significantly related to the overall relationship quality and aspects of adjustment for ASD-sibs, particularly in childhood. The findings suggest that ASD-sibs may be vulnerable to negative effects relating to have a …

Objective Measurement of Peripheral Edema as Symptomatic of Congestive Heart Failure
… known as peripheral edema. Assessing the severity level of pitting, or indentation, in peripheral edema can potentially provide insights about one's heart condition. When clinicians use digital manipulation to assess severity, the measurements are subjective. Objectifying measurements …

Semantic and spatio-temporal understanding for computer vision driven worker safety inspection and risk analysis
… method is introduced that evaluates worker-level risk from site photos and videos. This method evaluates worker state, which is based on workers' body pose, their protective equipment use, their interactions with tools and materials, the construction activity being performed, and hazards in …

Conception and Implementation of a Pharmacogenomic Plausibility Check: Integrating Molecular Data to Optimize Established Drug Therapy Safety Workflows
… plausibility warnings. The introduction of a new severity level for each pharmacogenomic alert allows for optimised prioritisation, effectively avoiding the problem of over-validation. The implementation of this new approach to evaluating drug therapy safety at the molecular level in hospitals …

Investigation of Trends and Predictive Effectiveness of Crash Severity Models
… regression to uncover temporal patterns in the severity level (fatal, serious injury, minor injury, slight injury or no injury) for persons involved in highway crashes in Connecticut, focusing on the demographic split between senior travelers (65 years and over) and non-senior travelers. …

A Longitudinal Approach to Understanding Individual Differences Affecting the Drinking Behavior Change Process
… variables of interest (e.g., drinking problem severity). This approach allows the inclusion of a relatively large number of variables to test complex hypotheses. The present study is a secondary data analysis of early (first three-month) Timeline Followback (TLFB) post-treatment drinking data …

Understanding Fatigue in Pediatric Sickle Cell Disease
… fatigue, including fatigue frequency, duration, severity, level of interference with daily activities, and how it presents (e.g., general fatigue, sleep/wake fatigue, or cognitive fatigue). They also reported on the youth's pain episodes in the past year (pain frequency, duration, severity), and …

Automated Bug Severity Prediction using Source Code Metrics, Static Analysis, and Code Representation
… for a defect prediction method to estimate the severity of the identified bugs so that the higher severity ones get immediate attention. In this thesis, we provide a quantitative and qualitative study on two popular datasets (Defects4J and Bugs.jar), using 10 common source code metrics, and also …

A Context Aware Classification System for Monitoring Driver’s Distraction Levels
… systems, the current measures neither detect the severity of the distraction levels nor the context-aware, which can aid in preventing accidents. Also, no compact study provides a complete model for transitioning control from the driver to the vehicle when a high degree of distraction is detected. …
