INTRODUCTION
Khatibi, Asadi and Hamidi (2009) investigated the relationship between job stress and organizational commitmentin National Olympic and Paralympic Academy. The purpose of this research was to study the relationship between job stress and organizational commitment in National Olympic and Paralympic Academy (NOPA) employees. Statistical population of this research included all employees (full time) of NOPA and statistical sample was equal to the statistical population (n=59). Job stress questionnaire (JSQ) and organizational commitment questionnaire were used to gather the data. The results indicated a negative significant relationship between job stress and organizational commitment, affective commitment and normative commitment, but there was not a significant relationship between job stress and continuance commitment. Etymologically the word information is a Latin word pronounced “informare” . Which mean to give form to, to shape, to form an idea of, or even to describe Brillhart, (2004).Forming an idea always occurs in the mind of a person, of a subject.
Information was used in English from as early as at least the 14th century but did not get its current spelling until the 16th century. Chaucer introduced the word information into the English language in one of The Canterbury Tales , written between 1372 and 1382. In Gulliver’s Travels (1727), Jonathan Swift applied the word information in a way that had appeared as early as the mid - 15th century and which sounds more familiar to us: “ I t was necessary to give the reader this information. ” Two main perspectives on information emerge: 1) information as something mental (the content), and 2) information as something material (the medium or the representation of information). The first view is often referred to as an intangible or nonmaterial entity; the second is material and informative. Paper, clay tablets, walls, or other objects give us plenty of room to write our thoughts down. There are many storage devices, even things such as the knot in your handkerchief. Almost anything can be used to store information Brillhart (2004). All it takes to store information by means of an object is an agreement that this particular configuration represents that information. Likewise, contemporary information technologies give us numerous devices that can store representations of information. These two concepts, information and the representation of information are often confused in everyday usage, but they are different and have different properties. For example, information can be both retained and given away. One cannot do that with the physical surrogate without creating a second physical version.
Furthermore, the medium is not the message, although it may strongly affect the message. Having a radio or a subscription to a daily newspaper or even access to an e - mail system does not guarantee that a person has read, seen, or heard the message and understood it................................more>>>>
