On October 23, 2010 in the city of Fujairah, east of Dubai, United Arab Emirates (UAE), United States medal winning swimmer Fran Crippen failed to finish the Fédération Internationale de Natation (FINA) 10 Kilometer Marathon Swimming World Cup open water race. The conditions of the water and exterior temperature were relevant factors contributing to the death of Fran Crippen. A discussion of risk communication, as an integral part of the risk management process, describes how this tragedy could have been avoided. This case study will address how the proper authorities could have employed the risk communications to prevent this tragedy.

Julie Tyler was recently hired as President of the Sacramento River Cats, a Triple-A affiliate of the San Francisco Giants. With a little over one month on the job, Julie encounters a situation she has never had to deal with when an earthquake strikes her facility. The River Cats are not severely impacted by the earthquake, but a rival organization (the Fresno Grizzlies; Triple-A affiliate of the Houston Astros) experiences some fairly serious damage and injuries. Julie has to decide whether to modify the schedule to meet the needs of the Grizzlies, to appease some of her other stakeholders with varying interests, and/or pursue a competitive advantage for her organization. Julie makes the decision to review a similar situation for guidance on her decision. The situation she decides to employ is a series relocation that the Houston Astros had to make to Tampa, Florida following the devastation created by Hurricane Harvey in August 2017. Her decision has to be made expeditiously as their next series with the Grizzlies takes place in four days.

Flexibility is promoted as essential to physical fitness, but the mechanisms limiting it are not fully understood.


To investigate the effects of general anesthesia on hamstring extensibility.


Repeated measures.


Hospital operating room.


Eight volunteers undergoing orthopedic surgeries unrelated to the tested limb.


Three measurements of passive knee extension (PKE) taken before and after administration of general anesthesia. The force applied during the measurements was consistent between trials.


Mean PKE range of motion (ROM) was significantly greater before anesthesia (75.0° ± 11.8°) than after (53.3° ± 17°; t = 5.6, P < .001). Pearson product correlation revealed a significant correlation between the mean difference in PKE ROM between treatment conditions and subjects’ body weight (r = .91, P < .05).


The findings might be attributable to diminished neural drive to the antagonist muscle groups and suggest a more complex neural control of flexibility than simply neural drive to an agonist muscle.
