Jackson and Eklund created two scales that have been proven to be psychometrically valid and reliable: the flow state scale-2 (which measures flow as a state), and the dispositional flow scale-2 (designed to measure flow as either a general trait or domain-specific trait).
In mathematics, Arnold's cat map is a chaotic map from the torus into itself, named after Vladimir Arnold, who demonstrated its effects in the 1960s using an image of a cat, hence the name. [1] It is a simple and pedagogical example for hyperbolic toral automorphisms .
A network of m interconnected queues is known as a Jackson network [11] or Jacksonian network [12] if it meets the following conditions: if the network is open, any external arrivals to node i form a Poisson process ,
The complexity of systems addressed by microscale models leads to complexity in the models themselves, and the specification of a microscale model can be tens or hundreds of times larger than its corresponding macroscale model. (The simplified example of Figure 2 has 25 times as many lines in its specification as does Figure 1.)
Michael Jackson and Bubbles is a porcelain sculpture (42 x 70.5 x 32.5 in) by the American artist Jeff Koons and manufactured in the Italian porcelain factory of Cesare Villari in Solagna, Italy. [1] It was created in 1988 within the framework of his Banality series .
The Multidimensional Aptitude Battery II is a group-administered intelligence test created by psychologist Douglas N. Jackson which is supposed to measure Verbal, Performance and Full Scale IQ. The battery consists of 10 subtests and is used for various professional, medical, military, government, law enforcement and employment settings.
A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1]An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system.
The model of hierarchical complexity (MHC) is a framework for scoring how complex a behavior is, such as verbal reasoning or other cognitive tasks. [1] It quantifies the order of hierarchical complexity of a task based on mathematical principles of how the information is organized, in terms of information science . [ 2 ]
