Extinction Event
An extinction event (also known as a mass extinction or biotic crisis) is a widespread and rapid decrease in the biodiversity on Earth. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the background extinction rate and the rate of speciation. Estimates of the number of major mass extinctions in the last 540 million years range from as few as five to more than twenty. These differences stem from disagreement as to what constitutes a "major" extinction event, and the data chosen to measure past diversity. The "Big Five" mass extinctions In a landmark paper published in 1982, Jack Sepkoski and David M. Raup identified five particular geological intervals with excessive diversity loss. They were originally identified as outliers on a general trend of decreasing extinction rates during the Phanerozoic, but as more stringent statistical tests have been applied t ...

Eventing
Eventing (also known as three day eventing or horse trials) is an equestrian event where a single horse and rider combine and compete against other competitors across the three disciplines of dressage, cross-country, and show jumping. This event has its roots in a comprehensive cavalry test that required mastery of several types of riding. The competition may be run as a one-day event (ODE), where all three events are completed in one day (dressage, followed by show jumping and then the cross-country phase) or a three-day event (3DE), which is more commonly now run over four days, with dressage on the first two days, followed by cross-country the next day and then show jumping in reverse order on the final day. Eventing was previously known as Combined Training, and the name persists in many smaller organizations. The term "Combined Training" is sometimes confused with the term "Combined Test", which refers to a combination of just two of the phases, most commonly dressage an ...

Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system. Impact events also appear to have played a significant role in the evolutionary h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event (computing)
In programming and software design, an event is an action or occurrence recognized by software, often originating asynchronously from the external environment, that may be handled by the software. Computer events can be generated or triggered by the system, by the user, or in other ways. Typically, events are handled synchronously with the program flow; that is, the software may have one or more dedicated places where events are handled, frequently an event loop. A source of events includes the user, who may interact with the software through the computer's peripherals - for example, by typing on the keyboard. Another source is a hardware device such as a timer. Software can also trigger its own set of events into the event loop, e.g. to communicate the completion of a task. Software that changes its behavior in response to events is said to be event-driven, often with the goal of being interactive. Description Event driven systems are typically used when there i ...

Event Chain Methodology
Event chain methodology is a network analysis technique that is focused on identifying and managing events and relationship between them (event chains) that affect project schedules. It is an uncertainty modeling schedule technique. Event chain methodology is an extension of quantitative project risk analysis with Monte Carlo simulations. It is the next advance beyond critical path method and critical chain project management. Event chain methodology tries to mitigate the effect of motivational and cognitive biases in estimating and scheduling. It improves accuracy of risk assessment and helps to generate more realistic risk adjusted project schedules. History Event chain methodology is an extension of traditional Monte Carlo simulation of project schedules where uncertainties in task duration and costs are defined by statistical distribution. For example, task duration can be defined by three point estimates: low, base, and high. The results of analysis is a risk adjusted projec ...

The Event
''The Event'' (stylized as THE EVƎNT) is an American television series containing elements of science fiction, action/adventure and political allegory. It was created by Nick Wauters and aired on NBC from September 20, 2010 to May 23, 2011. The plot centers on a group of extraterrestrials, some of whom have been detained by the United States government for sixty-six years since their ship crashed in Alaska, while others have secretly assimilated among the general populace. The series was picked up for a full first season of 22 episodes on October 18, 2010. On May 13, 2011, NBC canceled the series after one season. Synopsis Overview Near the end of World War II, a craft of undetermined origin crashed in the Brooks Range of northern Alaska. It carried passengers who appeared outwardly human, but were eventually determined to be of extraterrestrial origin. Their DNA is slightly less than one percent different from humans, and they age at a much slower rate. Since ninety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Event
A media event, also known as a pseudo-event, is an event, activity, or experience conducted for the purpose of media publicity. It may also include any event that is covered in the mass media or was hosted largely with the media in mind. In media studies, a media event is an established theoretical term first developed by Elihu Katz and Daniel Dayan in the 1992 book ''Media Events: The Live Broadcasting of History.'' Media events in this sense are ceremonial events with narrative progression that are live broadcast and gather a large segment of the population, such as royal weddings or funerals. The defining characteristics of a media event are that it is immediate (i.e., it is broadcast live), organized by a non-media entity, containing ceremonial and dramatic value, preplanning, and focusing on a personality, whether that be a single person or a group. The 2009 book ''Media Events in a Global Age'' updates the concept. The theory of media events has also been applied to social ...

Event Horizon
In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Wolfgang Rindler coined the term in the 1950s. In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. At that time, the Newtonian theory of gravitation and the so-called corpuscular theory of light were dominant. In these theories, if the escape velocity of the gravitational influence of a massive object exceeds the speed of light, then light originating inside or from it can escape temporarily but will return. In 1958, David Finkelstein used general relativity to introduce a stricter definition of a local black hole event horizon as a boundary beyond which events of any kind cannot affect an outside observer, leading to information and firewall paradoxes, encouraging the re-examination of the concept of local event horizons and the notion of black holes. Several theories were subsequently developed, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event (philosophy)
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. According to others, there are also events that involve nothing but the retaining of a property, e.g. the lawn's staying wet. Events are usually defined as particulars that, unlike universals, cannot repeat at different times. Processes are complex events constituted by a sequence of events. But even simple events can be conceived as complex entities involving an object, a time and the property exemplified by the object at this time. Traditionally, metaphysicians tended to emphasize static being over dynamic events. This tendency has been opposed by so-called process philosophy or process ontology, which ascribes ontological primacy to events and processes. Kim’s property-exemplification Jaegwon Kim theorized that events are structured. They are composed of three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event Management
Event management is the application of project management to the creation and development of small and/or large-scale personal or corporate events such as festivals, conferences, ceremonies, weddings, formal parties, concerts, or conventions. It involves studying the brand, identifying its target audience, devising the event concept, and coordinating the technical aspects before actually launching the event. The events industry now includes events of all sizes from the Olympics down to business breakfast meetings. Many industries, celebrities, charitable organizations, and interest groups hold events in order to market their label, build business relationships, raise money, or celebrate achievement. The process of planning and coordinating the event is usually referred to as event planning and which can include budgeting, scheduling, site selection, acquiring necessary permits, coordinating transportation and parking, arranging for speakers or entertainers, arranging deco ...

Event (probability Theory)
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. A single outcome may be an element of many different events, and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. An event consisting of only a single outcome is called an or an ; that is, it is a singleton set. An event S is said to if S contains the outcome x of the experiment (or trial) (that is, if x \in S). The probability (with respect to some probability measure) that an event S occurs is the probability that S contains the outcome x of an experiment (that is, it is the probability that x \in S). An event defines a complementary event, namely the complementary set (the event occurring), and together these define a Bernoulli trial: did the event occur or not? Typically, when the sample space is finite, any subset of the sample space is an event (that is, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mental Event
A mental event is any event that happens within the mind of a conscious individual. Examples include thoughts, feelings, decisions, dreams, and realizations. Some believe that mental events are not limited to human thought but can be associated with animals and artificial intelligence as well. Whether mental events are identical to complex physical events, or whether such an identity even makes sense, is central to the mind-body problem. Relation to mind-body problem Some state that the mental and the physical are the very same property which cause any event(s). This view is known as substance monism. An opposing view is substance dualism, which claims that the mental and physical are fundamentally different and can exist independently. A third approach is Donald Davidson's '' anomalous monism''. The Philosophy of Action states that every action is caused by prior thoughts or feelings, and understanding those mental events would in turn explain behavior. Physicalism, a for ...
