In philosophy, events are objects in time or instantiations of properties in objects. On some views, only changes in the form of acquiring or losing a property can constitute events, like the lawn's becoming dry. [1] According to others, there are also events that involve nothing but the retaining of a property, e.g. the lawn's staying wet.
e. In probability theory, an event is a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. [1] A single outcome may be an element of many different events, [2] and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. [3]
A sentinel event is "any unanticipated event in a healthcare setting that results in death or serious physical or psychological injury to a patient, not related to the natural course of the patient's illness". [1] Sentinel events can be caused by major mistakes and negligence on the part of a healthcare provider, and are closely investigated by ...
In value theory. In value theory, it is the amount of cause and effects of the chain of events before generating intrinsic value that separates high and low grades of instrumental value. The chain of events duration is the time it takes to reach the terminal event. In value theory this is generally the intrinsic value (also called terminal value).
Adverse event. An adverse event ( AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory ...
Event (computing), a software message indicating that something has happened, such as a keystroke or mouse click. Event (philosophy), an object in time, or an instantiation of a property in an object. Event (probability theory), a set of outcomes to which a probability is assigned. Event (relativity), a point in space at an instant in time, i.e ...
A black swan ( Cygnus atratus) in Australia. The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight. The term is based on a Latin expression which presumed that black swans did ...
In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Wolfgang Rindler coined the term in the 1950s. [1] In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. [2] At that time, the Newtonian theory of gravitation and the ...
