Calculation of effective stress, the theory of which is an effective theory. In mathematics and logic, effective is used to describe metalogical methods that fit the criteria of an effective procedure. In group theory, a group element acts effectively (or faithfully) on a point, if that point is not fixed by the action.
Effective altruism (EA) is a 21st-century philosophical and social movement that advocates impartially calculating benefits and prioritizing causes to provide the ...
Efficacy is the ability to perform a task to a satisfactory or expected degree. The word comes from the same roots as effectiveness, and it has often been used synonymously, although in pharmacology a distinction is now often made between efficacy and effectiveness.
In economics, organizational effectiveness is defined in terms of profitability and the minimisation of problems related to high employee turnover and absenteeism. [4] As the market for competent employees is subject to supply and demand pressures, firms must offer incentives that are not too low to discourage applicants from applying, and not too unnecessarily high as to detract from the firm ...
Here a commonly stated definition of effective mass is the inertial effective mass tensor defined below; however, in general it is a matrix-valued function of the wavevector, and even more complex than the band structure. Other effective masses are more relevant to directly measurable phenomena.
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
The definition of an effective method involves more than the method itself. In order for a method to be called effective, it must be considered with respect to a class of problems. Because of this, one method may be effective with respect to one class of problems and not be effective with respect to a different class.
Effective accelerationism, a portmanteau of "effective altruism" and "accelerationism", [4] is a fundamentally techno-optimist movement. [11]According to Guillaume Verdon, one of the movement's founders, its aim is for human civilization to "clim[b] the Kardashev gradient", meaning its purpose is for human civilization to rise to next levels on the Kardashev scale by maximizing energy usage.
