Stressors definition

The definition of what constitutes a stressor is also an important issue. So far, we have considered only external stressors stemming from the demands of the operating environment. Deficiencies in the design of the control panel. 

The expected recovery time for lakes enriched by anthropogenic Hg additions varies based on the definition used for recovery. Watershed attributes (e.g., Ag FLI) were found to be important stressors and more highly correlated to TTR than Hg emissions within the State of Michigan. This suggests that a watershed approach should be considered when dealing with the recovery of environmental system and that reducing Hg emissions alone may not result in reduced fluxes of Hg to aquatic systems. 

Additional information from the parent(s) or primary care taker(s) should include the child s medical and developmental history and the family s history of mental disorders and stressors. Reports of the direct observation of the youngster s behavior from the parent(s) or primary caretaker(s), school personnel, and others who have had contact with the child can help guide the definition of the most pressing target symptoms. 

Post traumatic stress disorder (PTSD) is the only psychiatric condition whose definition demands a particular stressor to precede its appearance. Unlike the other anxiety disorders, it is only in the past decade that the biology of PTSD has come under scrutiny. Furthermore, although PTSD can occur following various traumatic events (for example, sexual abuse, accidents and torture), most emphasis has been placed on combat-related disorders. 

Perhaps the easiest definition of ecological risk assessment is the probability of an effect occurring to an ecological system. Note that the word "probability" is key here. Important components of a risk assessment are the estimations of hazard and exposure due to a stressor. 

Direct effect — An effect where the stressor acts on the ecological component of interest itself, not through effects on other components of the ecosystem (compare with definition for indirect effect). 

The team-based PSF category has anon-trivial correlation with several other PSF categories. There are multiple explanations for this behavior. Team factors are likely to be correlated with the person-based factors because a team is composed of individuals, and therefore the individual characteristics of the team members affect the team. For example while communication is categorized as team-based, each member has a unique inherent personal communication style, and these styles combine together to form the team-based commrmication. However, we can state that by definition the communication must occur between two or more people, so while the inherent characteristics of each person do play a role, there cannot be communication without multiple individuals, i.e. ateam. It follows logically that there is a correlation between team-based and stressor factors because personal characteristics influence both elements. 

J. Rick liimer, BSc (Hons), PGCE, PhD, DSc, is an experimental research scientist, clinical tiialist, author, editor, and educator. He spent the first part of his professional career in the field of cardiovascular behavioral medicine, detailing the individual differences apparent in cardiovascular responses to behavioral and psychological stressors, including genetic influences upon them. He received two international awards for his research and is coeditor of the 2013 Springer volume Encyclopedia of Behavioral Medicine, the definitive work in this area. 

A study conducted by the U.S. National Transportation Safety Board reported that 73% of accidents were due to flight crew failures rather than technical-related problems [10]. Furthermore, the studies conducted by National Aeronautics and Space Administration (NASA) (in the form of pilot interviews, simulator observations, and accident analyses) reported that there was a definite need for more focus on team work and communication of pilots including command, decision making, and leadership [3]. Furthermore, the studies revealed that the crew factors such as the attitudes of the team toward communication and coordination, command responsibility, and recognition of stressor effects affect safety performance.
