Peer Evaluation Systems (PESs) allow members of student teams to provide one another with computer-mediated feedback in the form of qualitative, open-ended comments. The current research leverages unsupervised Natural Language Processing (NLP), namely Biterm Topic Modeling (BTM) and sentiment analysis, to uncover latent topics and degree of positivity and negativity expressed in peer feedback, respectively. BTM results revealed a 6-topic model that was reliably replicated over 10 Gibbs initializations 80% of the time. Topics were labeled Timely Communication, Idea Generation, Coordination & Adaptation, Work Quality, Team Support & Focusing, and Work Accountability. Qualitative comparison suggests that these topics demonstrate …
Trust Is Not Enough: Examining The Role Of Distrust In Human-Autonomy Teams, Sydney Begerowski
Trust Is Not Enough: Examining The Role Of Distrust In Human-Autonomy Teams, Sydney Begerowski
All Theses
As automation solutions in manufacturing grow more accessible, there are consistent calls to augment capabilities of humans through the use of autonomous agents, leading to human-autonomy teams (HATs). Many constructs from the human-human teaming literatures are being studied in the context of HATs, such as affective emergent states. Among these, trust has been demonstrated to play a critical role in both human teams and HATs, particularly when considering the reliability of the agent performance. However, the HAT literature fails to account for the distinction between trust and distrust. Consequently, this study investigates the effects of both trust and distrust in …
The Effects Of Accountability On Leniency Reduction In Self- And Peer Ratings On Team-Based Performance Appraisals, Brettney Smith
The Effects Of Accountability On Leniency Reduction In Self- And Peer Ratings On Team-Based Performance Appraisals, Brettney Smith
All Dissertations
The purpose of the present study was to assess the effects of accountability on leniency reduction on self- and peer ratings on team-based performance appraisals when they were used for different purposes (developmental versus evaluative purposes). Accountability was operationalized as participants being told they would have to justify their self- and peer ratings of team behaviors to a local nuclear process control plant supervisor (lab study) or to their professors (field study). In the lab study, purpose was operationalized as participants being told that they would have to complete the Team Behaviors Form (TBF) to receive course credit. In the …
Teams And Stress: A Meta-Analysis And Process Analysis, Brandy Brown
Teams And Stress: A Meta-Analysis And Process Analysis, Brandy Brown
All Dissertations
Past teamwork stress literature has experienced contradictory findings. As more reliable models of teamwork emerge, there is still a noticeable lack of information regarding how stress affects teamwork processes. This paper first reviews the current state of the team stress literature, where two types of stress for teams are explored: qualitative and quantitative stress. A meta-analysis examined the current literature on quantitative stress and the impact on team performance and effectiveness. Results from nine independent samples (N = 1,794) indicated that quantitative stress has a negative effect on team outcomes, ῤ = -.41. Second, a lab study sought to discover …
Physiological Compliance During Team Performance, Amanda Elkins
Physiological Compliance During Team Performance, Amanda Elkins
All Theses
Physiological compliance (PC) refers to the correlation between physiological measures of team members over time. The first goal of the current analyses was to generate several means to measure PC from heart rate variability (HRV) data. A second goal was to examine the relationship between PC and team performance during a building clearing task performed by 4-man teams. Teams were tasked with entering and clearing both real and simulated rooms populated with combatants (individuals with a weapon) and non-combatants (individuals without a weapon). Teams had to eliminate (shoot with a laser tag or simulated weapon) combatants and identify non-combatants (verbally …
