Information Systems Success Model
The information systems success model (alternatively ''IS success model'' or ''Delone and McLean IS success model'') is an information systems (IS) theory which seeks to provide a comprehensive understanding of IS success by identifying, describing, and explaining the relationships among six of the most critical dimensions of success along which information systems are commonly evaluated. Initial development of the theory was undertaken by William H. DeLone William Hook DeLone (born 1946) is an American organizational theorist, and Professor at the American University, Department of Information Technology, known for his work with Ephraim R.

Information Systems
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, information storage, store, and information distribution, distribute information. From a sociotechnical perspective, information systems are composed by four components: task, people, structure (or roles), and technology. Information systems can be defined as an integration of components for collection, storage and data processing, processing of data of which the data is used to provide information, contribute to knowledge as well as digital products that facilitate decision making. A computer information system is a system that is composed of people and computers that processes or interprets information. The term is also sometimes used to simply refer to a computer, computer system with software installed. "Information systems" is also an academic field study about systems with a specific reference to information and the complementary networks of computer hardware and soft ...

Success (concept)
Success is the state or condition of meeting a defined range of expectations. It may be viewed as the opposite of failure. The criteria for success depend on context, and may be relative to a particular observer or belief system. One person might consider a success what another person considers a failure, particularly in cases of direct competition or a zero-sum game. Similarly, the degree of success or failure in a situation may be differently viewed by distinct observers or participants, such that a situation that one considers to be a success, another might consider to be a failure, a qualified success or a neutral situation. For example, a film that is a commercial failure or even a box-office bomb can go on to receive a cult following, with the initial lack of commercial success even lending a cachet of subcultural coolness. It may also be difficult or impossible to ascertain whether a situation meets criteria for success or failure due to ambiguous or ill-defined definitio ...

Ephraim R
Ephraim (; he, ''ʾEp̄rayīm'', in pausa: ''ʾEp̄rāyīm'') was, according to the Book of Genesis, the second son of Joseph ben Jacob and Asenath. Asenath was an Ancient Egyptian woman whom Pharaoh gave to Joseph as wife, and the daughter of Potipherah, a priest of ʾĀwen. Ephraim was born in Egypt before the arrival of the Israelites from Canaan. The Book of Numbers lists three sons of Ephraim: Shuthelah, Beker, and Tahan. However, 1 Chronicles 7 lists eight sons, including Ezer and Elead, who were killed in an attempt to steal cattle from the locals. After their deaths he had another son, Beriah. He was the ancestor of Joshua, son of Nun ben Elishama, the leader of the Israelite tribes in the conquest of Canaan. According to the biblical narrative, Jeroboam, who became the first king of the Northern Kingdom of Israel, was also from the house of Ephraim. Biblical criticism The Book of Genesis related the name "Ephraim" to the Hebrew root פָּרָה (pārā), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediation (statistics)
In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator variable (also a mediating variable, intermediary variable, or intervening variable). Rather than a direct causal relationship between the independent variable and the dependent variable, a mediation model proposes that the independent variable influences the mediator variable, which in turn influences the dependent variable. Thus, the mediator variable serves to clarify the nature of the relationship between the independent and dependent variables. Mediation analyses are employed to understand a known relationship by exploring the underlying mechanism or process by which one variable influences another variable through a mediator variable.Cohen, J.; Cohen, P.; West, S. G.; Aiken, L. S. (2003) ''Applied multiple regression/c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
