Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by electrical signals. The parameters are useful for several branches of electrical engineering, including electronics, communication systems design, and especially for microwave engineering. The S-parameters are members of a family of similar parameters, other examples being: Y-parameters, Z-parameters, H-parameters, T-parameters or ABCD-parameters.
Person–environment fit (P–E fit) is the degree to which individual and environmental characteristics match. Person characteristics may include an individual's biological or psychological needs, values, goals, abilities, or personality, while environmental characteristics could include intrinsic and extrinsic rewards, demands of a job or role, cultural values, or characteristics of other individuals and collectives in the person's social environment.
Personality–job fit theory is a form of organizational psychology, that postulates that an individual's personality traits will reveal insight into their adaptability within an organization. The degree of confluence between a person and the organization is expressed as their Person-Organization (P-O) fit. This is also referred to as a person–environment fit. A common measure of the P-O fit is workplace efficacy - the rate at which workers are able to complete tasks. These tasks are affected by environmental factors within the workplace.
