It was during the Pleistocene that the most recent episodes of global cooling, or ice ages, took place. Much of the world's temperate zones were alternately covered by glaciers during cool periods and uncovered during the warmer interglacial periods when the glaciers retreated. Did this cause the Pleistocene extinctions? It doesn't seem likely; the large mammals of the Pleistocene weathered several climate shifts.

Many paleontologists study Pleistocene fossils in order to understand the climates of the past. The Pleistocene was not only a time during which climates and temperatures shifted dramatically; Pleistocene fossils are often abundant, well-preserved, and can be dated very precisely. Some, such as diatoms, foraminifera, and plant pollen, are both abundant and highly informative about paleoclimates. Today, there is concern about future climate change (e.g., global warming) and how it will affect us. Paleontologists who work on Pleistocene fossils are providing a growing amount of data on the effect of climate change on the Earth's biota, making it possible to understand the effects of future climate change.

Simulation is the imitation of the operation of a real-world process or system over time . [1] The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/ functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time.

Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering , testing , training , education , and video games . Often, computer experiments are used to study simulation models. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning. [2] Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist. [3]

Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and development in simulations technology or practice, particularly in the field of computer simulation .

Historically, simulations used in different fields developed largely independently, but 20th century studies of systems theory and cybernetics combined with spreading use of computers across all those fields have led to some unification and a more systematic view of the concept.

Physical simulation refers to simulation in which physical objects are substituted for the real thing (some circles [4] use the term for computer simulations modelling selected laws of physics , but this article does not). These physical objects are often chosen because they are smaller or cheaper than the actual object or system.

Interactive simulation is a special kind of physical simulation, often referred to as a human in the loop simulation, in which physical simulations include human operators, such as in a flight simulator or a driving simulator .

Simulation Fidelity is used to describe the accuracy of a simulation and how closely it imitates the real-life counterpart. Fidelity is broadly classified as 1 of 3 categories: low, medium, and high. Specific descriptions of fidelity levels are subject to interpretation but the following generalization can be made:

Simulation...is not fully integrated into the development of skills for practicing nurses. Simulation has become more integrated into the education of nurses and physicians in the past 20 years, but is not fully integrated into the development of skills for practicing nurses. Despite recommendations for use of simulation, and growing integration of simulation into education, empirical evidence for the impact of simulation on patient outcomes is still underdeveloped. This article will provide an overview of simulation techniques and uses; review selected emerging research linking simulation to patient outcomes; discuss current uses of simulation by practicing nurses; and recommend strategies to develop a simulation program.

This refers to bringing the simulation (and simulator) to the site where the learner is practicing. This could occur in an ER trauma bay or surgical suite.

Regular in situ simulation training of paediatric medical emergency team tp improve hospital response to deteriorating patients
( Theilen et al., 2012 )

Prospective cohort study of all deteriorating in-patients requiring admission to a PICU for one year before and after implementing a pediatric medical emergency team (pMET) and concurrent team training which was comprised of in situ simulation. pMET team included physicians and nurses.

Deteriorating patients were recognized more promptly post pMET (p<.0001), were transferred more often to high dependency care (p=.021) and more rapidly escalated to intensive care (p=.024).
