  1. Ecological Systems Theory

    Refimprove date April 2008 Ecological Systems Theory , also called Development in Context or Human Ecology theory , specifies four types of nested environmental systems, with bi directional influences within and between the systems. Overview Urie Bronfenbrenner is generally regarded as one of the world s leading scholars in the field of developmental psychology . Citation needed date June 2010 His Ecological Systems Theory holds that development reflects the influence of several environmental systems, and it identifies five environmental systems Micro system The setting in which the individual lives. These contexts include the person s family, peers, school, and neighborhood. It is in the micro system that the most direct interactions with social agents take place with parents, peers, and teachers, for example. The individual is not a passive recipient of experiences in these settings, but someone who helps to construct the settings.

  1. Open system (systems theory)

    About systems theory Open system disambiguation File Basic Open System Model.gif 320px thumb right Open System Model basics An open system is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept see below . An open system should be contrasted with the concept of an isolated system which exchanges neither energy, matter, or information with its environment. The concept of an open system was formalized within a framework that enabled one to interrelate the Organismic theory theory of the organism , thermodynamics , and Theory of Evolution evolutionary theory . ref Luhmann, Niklas. Social Systems . Stanford Stanford University Press, 1995 pp. 6 7 ref This concept was expanded upon with the advent of information theory and subsequently systems theory .

  1. Flatness (systems theory)

    Flatness in systems theory is a system property that extends the notion of Controllability from LTI system theory linear systems to Nonlinearity nonlinear dynamical system s. A system that has the flatness property is called a flat system . Flat systems have a fictituous flat output , which can be used to explicitly express all states and inputs in terms of the flat output and a finite number of its derivatives. Flatness in systems theory is based on the mathematical notion of Flat morphism flatness in commutative algebra and is applied in control theory .

Greatly simplifying his model ref Easton, David. 1965 . A Systems Analysis of Political Life . New York Wiley. ref Step 1. changes in the social or physical environment surrounding a political system produce demands and supports for action or the status quo directed as inputs towards the political system, through political behavior. Step 2, these demands and supporting groups stimulate competition in a political system, leading to decisions or outputs directed at some aspect of the surrounding social or physical environment. Step 3, after a decision or output is made e.g., a specific policy , it interacts with its environment, and if it produces change in the environment, there are outcomes.

  1. T-theory

    T theory is a branch of discrete mathematics dealing with analysis of tree graph theory tree s and discrete metric spaces . General history As per Andreas Dress , T theory originated from a question raised by Manfred Eigen , a recipient of the Nobel Prize in Chemistry , in the late seventies. He was trying to fit twenty distinct transfer RNA t RNA molecule s of the Escherichia coli E. Coli bacterium into a tree. One of the most important concepts of T theory is the tight span of a metric space. If X is a metric space, the tight span T X of X is, up to isomorphism, the unique minimal injective metric space that contains X . John Isbell was the first to discover the tight span in 1964, which he called the injective envelope . Dress independently constructed the same construct, which he called the tight span. Application areas Phylogenetic analysis, which is used to create phylogenetic tree s. Online algorithm s k server problem k server problem Recent developments Bernd Sturmfels , Professor of Mathematics and Computer Science at University of California, Berkeley Berkeley , and Josephine Yu classified six point metrics using T theory.

    One source date May 2010 The term theory theory or theory theory is a theory in cognitive development that children construct theories to explain everything they experience. ref name KSB The developing person through childhood and adolescence , Kathleen Stassen Berger, 2005, Chapter 9 The Play Years Cognitive Development , p.262 of 608 pages , web http books.google.com books?id fCfiqDisIH8C&pg PA262 &lpg PA262 Books Google IH8C . ref According to theory theory, the best idea and explanation of mental processes ref name KSB in young children is that humans always seek reasons, causes, and underlying principles for what they experience. The essential idea of theory theory is that children do not want simple logical definitions but, rather, seek fuller explanations of various things, especially of those that involve them. small ref name KSB small The term originated in the 20th century, and the concept is also referred to as model theory . TOC Theory theory differs from the Theory of mind Theory of Mind which concerns mental states of people in that the full scope of theory theory also concerns mechanical devices or other objects, beyond just thinking about people and their viewpoints.
