The influence of digital technologies on resilient performance: Contributions, drawbacks, and a research agenda
Appl Ergon. 2024 Apr 23;118:104290. doi: 10.1016/j.apergo.2024.104290. Online ahead of print.ABSTRACTThe growing use of digital technologies (DTs) has a myriad of implications to socio-technical systems, which are not yet fully recognised. This paper investigates the contributions and drawbacks of DTs to resilient performance (RP), an aspect that so far has received less attention in comparison to others such as efficiency. To this end, a survey questionnaire was applied to 79 academics and practitioners linked to resilience engineering. Data analysis involved descriptive statistics and a thematic analysis of the open-text...

Operator selection for human-automation teaming: The role of manual task skill in predicting automation failure intervention
We examined whether manual aircraft conflict detection skill predicted participants' ability to respond to conflict detection automation failures in simulated air traffic control. In a conflict discrimination task (to assess manual skill), participants determined whether pairs of aircraft were in conflict or not by judging their relative-arrival time at common intersection points. Then in a simulated air traffic control task, participants supervised automation which either partially or fully detected and resolved conflicts on their behalf. Automation supervision required participants to detect when automation may have fail...

Equivalent weight: Application of the assessment method on real task conducted by railway workers wearing a back support exoskeleton
Appl Ergon. 2024 Apr 15;118:104278. doi: 10.1016/j.apergo.2024.104278. Online ahead of print.ABSTRACTCommonly used risk indexes, such as the NIOSH Lifting Index, do not capture the effect of exoskeletons. This makes it difficult for Health and Safety professionals to rigorously assess the benefit of such devices. The community requires a simple method to assess the effectiveness of back-support exoskeleton's (BSE) in possibly reducing ergonomic risk. The method introduced in this work is termed "Equivalent Weight" (EqW) and it proposes an interpretation of the effect built on the benefit delivered through reduced activatio...

Analysis of driver behavior at grade-separated intersections to support design
Appl Ergon. 2024 Apr 15;118:104287. doi: 10.1016/j.apergo.2024.104287. Online ahead of print.ABSTRACTUnderstanding driver behaviors in varied traffic scenarios is critical to the design of safe and efficient roadways and traffic control device. This research presents an analysis of driver cognitive workload, situation awareness (SA) and performance for three different scenarios, including a standard intersection and contraflow grade-separated intersections (C-GSI) and quadrant GSI (Q-GSI) with lane assignment sign manipulations. The study used a simulator-based driving experiment with application of the NASA Task Load Inde...

Unlatching school bus seat belt buckles: Considerations for young passengers
This study evaluated the strength capabilities of children and their abilities to unlatch a school bus seat belt when a school bus is in both the upright and rolled-over orientations. Push force exertions on a seat belt buckle push button were measured and compared to the seat belt assembly release force requirements specified in Federal Motor Vehicle Safety Standard (FMVSS) No. 209. Results of the study suggested that children do not have the strength to exert the maximum force of 133 N to release a seat belt assembly as specified in FMVSS No. 209; however, most children could unlatch a typical school bus seat belt assemb...

Impact of repetitive mouse clicking on forearm muscle fatigue and mouse aiming performance
Appl Ergon. 2024 Apr 6;118:104284. doi: 10.1016/j.apergo.2024.104284. Online ahead of print.ABSTRACTExercise induced performance fatigue has been shown to impair many aspects of fine motor function in the distal upper limb. However, most fatiguing protocols do not reflect the conditions experienced with computer use. The purpose of this study was to determine how a prolonged, low-force mouse clicking fatigue protocol impacts performance fatigue of the distal upper limb for gamers and non-gamers. Participants completed a total of 1 h of mouse clicking at 5 clicks per second. Muscle fatigue and performance were intermittentl...
