The Purpose Of A System Is What It Does
The purpose of a system is what it does (POSIWID) is a systems thinking heuristic coined by Stafford Beer, who observed that there is "no point in claiming that the purpose of a system is to do what it constantly fails to do." The term is widely used by Systems theory, systems theorists, and is generally invoked to counter the notion that the purpose of a system can be read from the intentions of those who systems design, design, operate, or promote it. When a system's side effects or unintended consequences reveal that its behavior is poorly understood, then the POSIWID perspective can balance political understandings of system behavior with a more straightforwardly descriptive view. Origins of the term Stafford Beer coined the term POSIWID and used it many times in public addresses. In his address to the University of Valladolid, Spain, in October 2001, he said: Uses From a Cybernetics, cybernetic perspective, complex systems are not controllable by simple notions of management ...

Moral Judgment
Moral reasoning is the study of how people think about right and wrong and how they acquire and apply moral rules. It is a subdiscipline of moral psychology that overlaps with moral philosophy, and is the foundation of descriptive ethics. Description Starting from a young age, people can make moral decisions about what is right and wrong. Moral reasoning, however, is a part of morality that occurs both within and between individuals. Prominent contributors to this theory include Lawrence Kohlberg and Elliot Turiel. The term is sometimes used in a different sense: reasoning under conditions of uncertainty, such as those commonly obtained in a court of law. It is this sense that gave rise to the phrase, "To a moral certainty;" however, this idea is now seldom used outside of charges to juries. Moral reasoning is an important and often daily process that people use when trying to do the right thing. For instance, every day people are faced with the dilemma of whether to lie in ...

Heuristics
A heuristic (; ), or heuristic technique, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples that employ heuristics include using trial and error, a rule of thumb or an educated guess. Heuristics are the strategies derived from previous experiences with similar problems. These strategies depend on using readily accessible, though loosely applicable, information to control problem solving in human beings, machines and abstract issues. When an individual applies a heuristic in practice, it generally performs as expected. However it can alternatively c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duck Test
The duck test is a form of abductive reasoning, usually expressed as "If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck." The test implies that a person can identify an unknown subject by observing that subject's habitual characteristics. It is sometimes used to counter abstruse arguments that something is not what it appears to be. History The French automaton maker Jacques de Vaucanson created a mechanical duck in 1738. The mechanical duck would quack, move its head to eat grain which it would appear to digest, and after a short time would excrete a mixture that looked and smelled like duck droppings. The irony is that while the phrase is often cited as proof of abductive reasoning, it is not proof, as the mechanical duck is still not a living duck. In popular culture Douglas Adams parodied this test in his book '' Dirk Gently's Holistic Detective Agency'': Monty Python also referenced the test in the Witch Logic scene ...

Management
Management (or managing) is the administration of an organization, whether it is a business, a nonprofit organization, or a Government agency, government body. It is the art and science of managing resources of the business. Management includes the activities of setting the strategic management, strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its goal, objectives through the application of available Resource (economics), resources, such as financial, natural resources, natural, technological, and human resources. "Run the business" and "Change the business" are two concepts that are used in management to differentiate between the continued delivery of goods or services and adapting of goods or services to meet the changing needs of customers - see trend (other), trend. The term "management" may also refer to those people who manage an organization—managers. Some people study management at colleges or univer ...

Complex Systems
A complex system is a system composed of many components which may interact with each other. Examples of complex systems are Earth's global climate, organisms, the human brain, infrastructure such as power grid, transportation or communication systems, complex software and electronic systems, social and economic organizations (like cities), an ecosystem, a living cell, and ultimately the entire universe. Complex systems are systems whose behavior is intrinsically difficult to model due to the dependencies, competitions, relationships, or other types of interactions between their parts or between a given system and its environment. Systems that are " complex" have distinct properties that arise from these relationships, such as nonlinearity, emergence, spontaneous order, adaptation, and feedback loops, among others. Because such systems appear in a wide variety of fields, the commonalities among them have become the topic of their independent area of research. In many cases, it ...

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

Dictum
In general usage, a dictum ( in Latin; plural dicta) is an authoritative or dogmatic statement. In some contexts, such as legal writing and church cantata librettos, ''dictum'' can have a specific meaning. Legal writing In United States legal terminology, a ''dictum'' is a statement of opinion considered authoritative (although not binding), given the recognized authoritativeness of the person who pronounced it."dictum", Black's Law Dictionary (8th ed. 2004); C.J.S. Courts §§ 142-143. There are multiple subtypes of ''dicta'', although due to their overlapping nature, legal practitioners in the U.S. colloquially use ''dictum'' to refer to any statement by a court the scope of which extends beyond the issue before the court. ''Dicta'' in this sense are not binding under the principle of ''stare decisis'', but tend to have a strong persuasive effect, by virtue of having been stated in an authoritative decision, or by an authoritative judge, or both. These subtypes include: * '' di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cybernetician
A cyberneticist or a cybernetician is a person who practices cybernetics. Heinz von Foerster once told Stuart Umpleby that Norbert Wiener preferred the term "cybernetician" rather than "cyberneticist", perhaps because Wiener was a mathematician rather than a physicist. The word "cyberneticist" was used by Nicolas Rashevsky who began as a theoretical physicist. Robert Rosen, who began his career as a mathematician, regarded neurocybernetics—and more generally biocybernetics—as fields closely allied to mathematical biology and mathematical biophysics in which control theory and dynamical system theories also play significant roles. Today "cybernetician" is preferred by members of the American Society for Cybernetics.
