Evaluation of Driver Performance While Making Unprotected Intersection Turns Utilizing Naturalistic Data Integration Methods
… to study driver behavior at intersections, in a naturalistic paradigm. A data-mining algorithm was used to aggregate the data from two different naturalistic databases to obtain instances of unprotected turns at the same intersection. Several dependent variables were analyzed which included …

Towards Naturalistic Data Collection in South Africa: Feasibility of Home-based Smartphone Recordings of Caregiver-Child Interactions for Coding with the Joint Engagement Rating Inventory (JERI)
Naturalistic developmental behavioural interventions (NDBI) represent an evidence-based group of early interventions for autism. The COVID-19 pandemic forced autism interventions globally to switch to telehealth that utilised smartphone technology. Even though the evidence base for NDBI in low-and …

Application of Naturalistic Truck Driving Data to Analyze and Improve Car Following Models
… are calibrated to individual drivers with the naturalistic data. The models used are the GHR, Gipps, Intelligent Driver, Velocity Difference, Wiedemann, and the Fritzsche model. This research effort also analyzes the Wiedemann car-following model using car-following periods that occur at …

Doing dialogue differently: case studies of teacher collaborative discourse in Malaysian secondary schools
… ‘non-Western’ contexts and using relatively ‘naturalistic data’ without significant external or researcher intervention/facilitation. To address this problematic, this thesis uses relatively naturalistic data to examine how teachers learn through collaborative discourse within professional …

Unsupervised learning of lexical subclasses from phonotactics
… demonstrates the learnability of sublexica from naturalistic data. The learned sublexica also replicate linguistic characterizations of actual sublexica proposed in previous literature, such as the biased distribution of (certain substrings of) segments to particular sublexica. In addition, the …

Newly Licensed Teenaged Drivers: A Field Study Evaluation of Eye Glance Patterns on Straight Road Segments
… Currently there is a lack of continuous and naturalistic data in the field of teenaged driving. The purpose of this study was to obtain continuous performance data from a naturalistic setting by equipping the personal vehicles of newly licensed teenaged drivers with a data collection system …

Deans of nursing: pathways to the deanship
… and professional identity. The study design was naturalistic. Data were collected by survey, life history interviews, and through document search of curriculum vitae. Field notes were recorded throughout the data collection period. Data were analyzed using Spradley's (1979) ethnographic analysis …

Evaluation of a server intervention program for preventing drunk driving
… to drink six alcoholic beverages in two hours. Naturalistic data were collected by having a partner with a hidden microphone record all interactions between the server and pseudopatron. The partner also noted any signs of intoxication exhibited by the pseudopatron. The results revealed that …

Negotiation of problem definition in the clinical psychology appointments of a learning disability service
… (Potter & Wetherell, 1987) was used to examine naturalistic data from audio recordings of appointments. Participants included psychologists carrying out appointments, people with learning disabilities and their family members or carers. The analysis revealed a number of common processes involved …

Blame it on her genes : on performativity, politics, and the consumption of prevention
… contexts. Through the analysis of naturalistic data, which provides rich and detailed accounts of interactions, this thesis moves beyond the elaboration of thick descriptions to engage with the politics behind performatives. A particular scrutiny is put on the set of practices, …

Linguistic Transfer in Andean Spanish: Syntax or Pragmatics?
… properties in Spanish and Quechua. In addition, naturalistic data were collected and an elicitation study on wh-questions and answers was created to study the pragmatics of focus in Spanish and Quechua. The subjects for the study were Quechua-Spanish bilinguals from Bolivia and Ecuador, and adult …

End-user modification and correction of home activity recognition
… from a pilot evaluation of Distinguish on naturalistic data gathered continuously from an instrumented home over a period of a month. Without any knowledge of the target home or its occupant's behaviors and no training data other than common sense information contributed by web users, the …

The fundamental difference between child and adult language acquisition: a longitudinal, naturalistic study of parameter resetting in Swedish interlanguage
… a novel approach; it examines longitudinal, naturalistic data on the acquisition of Swedish syntax by children and adults (n = 9). Subjects comprise native speakers of Iraqi Arabic and Finnish. Each subject was recorded three times over the course of one year during informal speech …

The development of a holistic approach to modeling driver behavior : accounting for driver heterogeneity in car-following models
… and challenges with collecting high-resolution data have stunted advancements in this domain. Thus, methodologies to adequately capture naturalistic behavioral heterogeneity are largely missing from the literature. For this dissertation, a sample from the second Strategic Highway Research …

Emotional Impacts on Driver Behavior: An Emo-Psychophysical Car-Following Model
This research effort aims to create a new car-following model that accounts for the effects of emotion on driver behavior. This research effort is divided into eight research milestones: (1) the development of a segmentation and clustering algorithm to perform new investigations into driver …

Analytic Assessment of Collision Avoidance Systems and Driver Dynamic Performance in Rear-End Crashes and Near-Crashes
… automotive rear-end crashes. A method for using naturalistic data in the evaluation of CAS algorithms is described and applied to three algorithms. Time-series parametric data collected during 13 rear-end crashes and 70 near-crashes are input into models of collision avoidance algorithms to …

Investigating default mode network activation during external task switches and movie watching
… its recruitment during various transitions in naturalistic stimuli, such as movies. The findings indicate that DMN subnetworks are sensitive to objective transitions in stimuli and subjective event boundaries, supporting the DMN’s role in interpreting continuous external events and detecting …

Towards a Comprehensive Bicycle Motion Behavior Model and Naturalistic Cycling Dataset
… and motion behavior. Furthermore, the lack of naturalistic data has limited the validation of this model. This research aims at developing a descriptive model that is capable of capturing the inherent non-lane-based traffic behavior characteristics of bicycle traffic and provides a methodology …

Threat assessment for safe navigation in environments with uncertainty in predictability
… validated using a large real-world intersection dataset, and can be used as part of future driver assistance systems. They are also compared to three popular traditional methods, and the results show significant and consistent improvements with the developed algorithms. The second part of the …

The acquisition of the Pro-drop parameter by non-native speakers of Spanish
… These principles interact with environmental data to determine the particular language that the child will learn. Research into L1 acquisition strongly suggests that a child's parameter setting process takes place on the basis of fairly minimal positive evidence derived from the linguistic …
