Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering/systems engineering, and the subset system safety engineering. Safety engineering assures that a life-critical system behaves as needed, even when components fail.
Discourse is a generalization of the notion of a conversation to any form of communication. Discourse is a major topic in social theory, with work spanning fields such as sociology, anthropology, continental philosophy, and discourse analysis. Following work by Michel Foucault, these fields view discourse as a system of thought, knowledge, or communication that constructs our world experience. Since control of discourse amounts to control of how the world is perceived, social theory often studies discourse as a window into power. Within theoretical linguistics, discourse is understood more narrowly as linguistic information exchange and was one of the major motivations for the framework of dynamic semantics. In these expressions, ' denotations are equated with their ability to update a discourse context.
General semantics is a school of thought that incorporates philosophic and scientific aspects. Although it does not stand on its own as a separate school of philosophy, a separate science, or an academic discipline, it describes itself as a scientifically empirical approach to cognition and problem solving. It has been described by nonproponents as a self-help system, and it has been criticized as having pseudoscientific aspects, but it has also been favorably viewed by various scientists as a useful set of analytical tools albeit not its own science.
In computer science, a compiler-compiler or compiler generator is a programming tool that creates a parser, interpreter, or compiler from some form of formal description of a programming language and machine.
Mario Augusto Bunge was an Argentine-Canadian philosopher and physicist. His philosophical writings combined scientific realism, systemism, materialism, emergentism, and other principles.
A safety-critical system or life-critical system is a system whose failure or malfunction may result in one of the following outcomes:
Frank Stagg was a Southern Baptist theologian, seminary professor, author, and pastor over a 50-year ministry career. He taught New Testament interpretation and Greek at New Orleans Baptist Theological Seminary from 1945 until 1964 and at the Southern Baptist Theological Seminary in Louisville, Kentucky from 1964 until 1978. His publications, recognitions and honors earned him distinction as one of the eminent theologians of the past century. Other eminent theologians have honored him as a "Teaching Prophet."
No one...has ever taken the New Testament more seriously than Frank Stagg, who spent his entire life wrestling with it, paying the price in sweat and hours in an unrelenting quest to hear the message expressed in a language no longer spoken and directed toward a cultural context so foreign to the modern reader.
Jerry Alan Fodor was an American philosopher and the author of works in the fields of philosophy of mind and cognitive science. His writings in these fields laid the groundwork for the modularity of mind and the language of thought hypotheses, and he is recognized as having had "an enormous influence on virtually every portion of the philosophy of mind literature since 1960." At the time of his death in 2017, he held the position of State of New Jersey Professor of Philosophy, Emeritus, at Rutgers University, and had taught previously at the City University of New York Graduate Center and MIT.
Common and special causes are the two distinct origins of variation in a process, as defined in the statistical thinking and methods of Walter A. Shewhart and W. Edwards Deming. Briefly, "common causes", also called natural patterns, are the usual, historical, quantifiable variation in a system, while "special causes" are unusual, not previously observed, non-quantifiable variation.
In computer science, type safety and type soundness are the extent to which a programming language discourages or prevents type errors. Type safety is sometimes alternatively considered to be a property of facilities of a computer language; that is, some facilities are type-safe and their usage will not result in type errors, while other facilities in the same language may be type-unsafe and a program using them may encounter type errors. The behaviors classified as type errors by a given programming language are usually those that result from attempts to perform operations on values that are not of the appropriate data type, e.g., adding a string to an integer when there's no definition on how to handle this case. This classification is partly based on opinion.
John Gall was an American author, scholar, and pediatrician. Gall is known for his 1975 book General systemantics: an essay on how systems work, and especially how they fail..., a critique of systems theory. One of the statements from this book has become known as Gall's law.
Tsongkhapa was an influential Tibetan Buddhist monk, philosopher and tantric yogi, whose activities led to the formation of the Gelug school of Tibetan Buddhism.
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time.
Alexander Bryan Johnson, was a British-born American philosopher and semanticist. He immigrated to the United States as a child and worked as a banker in Utica, New York. He wrote about economics, language, and the nature of knowledge.
Jacob Milgrom was a prominent American Jewish Bible scholar and Conservative rabbi. Milgrom's major contribution to biblical research was in the field of cult and worship. Although he accepted the documentary hypothesis, contrary to the classical bible critics, he traced a direct line of development from the Priestly Code (P), to the Holiness Code (H), to the cultic innovations of Ezekiel, to the cultic writings of the Dead Sea sect and finally to Jewish law (halacha) of the Mishnah and Talmud. Best known for his comprehensive Torah commentaries and work on the Dead Sea Scrolls, he also published extensively on the Book of Ezekiel.
In the chemical and process industries, a process has inherent safety if it has a low level of danger even if things go wrong. Inherent safety contrasts with other processes where a high degree of hazard is controlled by protective systems. As perfect safety cannot be achieved, common practice is to talk about inherently safer design. “An inherently safer design is one that avoids hazards instead of controlling them, particularly by reducing the amount of hazardous material and the number of hazardous operations in the plant.”
Probabilistic design is a discipline within engineering design. It deals primarily with the consideration and minimization of the effects of random variability upon the performance of an engineering system during the design phase. Typically, these effects studied and optimized are related to quality and reliability. It differs from the classical approach to design by assuming a small probability of failure instead of using the safety factor. Probabilistic design is used in a variety of different applications to assess the likelihood of failure. Disciplines which extensively use probabilistic design principles include product design, quality control, systems engineering, machine design, civil engineering and manufacturing.
Norman Gall is an American reporter and commentator on Latin American affairs. He has contributed to such periodicals as Forbes, The Economist, and The Wall Street Journal, and since 1987 has been the executive director of the Fernand Braudel Institute of World Economics, based in São Paulo, Brazil.
Mathematics: The Loss of Certainty is a book by Morris Kline on the developing perspectives within mathematical cultures throughout the centuries.
Human factors are the physical or cognitive properties of individuals, or social behavior which is specific to humans, and which influence functioning of technological systems as well as human-environment equilibria. The safety of underwater diving operations can be improved by reducing the frequency of human error and the consequences when it does occur. Human error can be defined as an individual's deviation from acceptable or desirable practice which culminates in undesirable or unexpected results. Human factors include both the non-technical skills that enhance safety and the non-technical factors that contribute to undesirable incidents that put the diver at risk.
[Safety is] An active, adaptive process which involves making sense of the task in the context of the environment to successfully achieve explicit and implied goals, with the expectation that no harm or damage will occur. – G. Lock, 2022
Dive safety is primarily a function of four factors: the environment, equipment, individual diver performance and dive team performance. The water is a harsh and alien environment which can impose severe physical and psychological stress on a diver. The remaining factors must be controlled and coordinated so the diver can overcome the stresses imposed by the underwater environment and work safely. Diving equipment is crucial because it provides life support to the diver, but the majority of dive accidents are caused by individual diver panic and an associated degradation of the individual diver's performance. – M.A. Blumenberg, 1996
