An Examination Of Psychological Meaningfulness, Safety, And Availability As The Underlying Mechanisms Linking Job Features And Personal Characteristics To Work Engagement, Holly Jacobs

FIU Electronic Theses and Dissertations

The present study tested a nomological net of work engagement that was derived from its extant research. Two of the main work engagement models that have been presented and empirically tested in the literature, the JD-R model and Kahn’s model, were integrated to test the effects that job features and personal characteristics can have on work engagement through the psychological conditions of meaningfulness, safety, and availability. In this study, safety refers to psychological perceptions of safety and not workplace safety behaviors. The job features that were tested in this model included person-job fit, autonomy, co-worker relations, supervisor support, procedural justice, …

Selection System Prediction Of Safety: A Step Toward Zero Accidents In South African Mining, Rachel Aguilera-Vanderheyden

All Graduate Theses, Dissertations, and Other Capstone Projects

Underground mining is a high-risk industry with a history of frequent accidents and deaths. The purpose of this study is to identify cognitive and psychomotor factors that may predict, and ultimately be used to prevent injuries. More specifically, I tested the extent to which the Raven's Progressive Matrices, a measure of cognitive ability, and the Vienna Test System, a measure of psychomotor ability, predicted injury - It was hypothesized that the Raven's scores would explain additional unique variance beyond the psychomotor scores alone. The results show that the Raven's scores were significantly predictive of Serious Injuries when analyzed in isolation, …

The Effects Of External Motivation And Real-Time Automated Feedback On Speeding Behavior In A Naturalistic Setting, Ian J. Reagan, James P. Bliss, Ron Van Houten, Bryan W. Hilton

Psychology Faculty Publications

Objective: In this field experiment, the authors tested an alerting system and a monetary incentive system with the objective of reducing speeding more than 5 mph faster than the posted speed limit.

Background: Speeding is a factor in a significant number of traffic fatalities. The systems tested in this project have been evaluated outside but not within the United States. These studies indicated that similar systems led to reductions in speeding.

Method: For this study, eight vehicles were instrumented such that vehicle speed and speed limits were linked in real time. A total of 50 participants drove assigned vehicles for …
