“The ADA prohibits discrimination on the basis of disability in employment, state and local government, public accommodations, commercial facilities, transportation, and telecommunications. It also applies to the United States Congress. To be protected by the ADA, one must have a disability or have a relationship or association with an individual with a disability. An individual with a disability is defined by the ADA as a person who has a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment. The ADA does not specifically name all of the impairments that are covered” (http://www.usdoj.gov/crt/ada/cguide.pdf, p. 3 of 23).

Abstract
In systems thinking divisions apparent in science specializations are seen “as arbitrary and man made” (Checkland, 1981, p. 4). A key idea embedded in systems theory is that it can assist us in understanding of phenomena and that its holistic emphasis will promote orderly thinking. According to Checkland (1981), there are natural systems, designed systems, abstract systems, and human activity systems (p. 112). Human activity systems can be broken down into examples of open systems that are relationship dependent. Change is inherent in human systems, as the intricacy of the relationships in these kinds of systems require continuous adaptations if the system is to remain stable. Checkland viewed human activity systems as wholes that are emphasized by the existence of other systems.
