Payroll time conversion is simply the process of converting minutes to hours for payroll purposes. For example, 30 minutes would be entered into payroll as 0.5 hours. Some organizations only enter a single decimal for hours, so minutes are rounded. If only a single decimal place is used, typically organizations will round up.
A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath. Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality.
In humans, yawning is often triggered by others yawning (e.g., seeing a person yawning, talking to someone on the phone who is yawning) and is a typical example of positive feedback. This contagious yawning has also been observed in chimpanzees, dogs, and can occur across species.nother hypothesis is that yawns are caused by the same chemicals (neurotransmitters) in the brain that affect emotions, mood, appetite, and other phenomena. These chemicals include serotonin, dopamine, glutamic acid, and nitric oxide.
