Human beings message systems 409

Only after entering the limbic system does the olfactory message pass to the cerebral hemispheres, which form the major part of the human brain, where cognitive recognition occurs and the ability to associate the smell with its name. By this sequence of events our full awareness of a smell takes place only after the deepest parts of the unconscious have been activated. As a result, even without conscious recognition, smell can be the most evocative of our senses, linking us to past experiences and stirring our emotions at a level that we find hard to explain. 

The next phase of research was conducted with animal models and, later, cell systems. This approach examined single compounds and was frequently not able to be translated to the human situation. Experimental doses were administered in ways that were inconsistent with the natures, times, and levels associated with human exposure. The failure to identify and agree on standardized experimental protocols and methodologies made it difficult to compare data from different laboratories and to send a clear message to the consumer, over and above the necessary but unexciting exhortation to eat more frait and vegetables. ... 

Decryption Failure. Records preserved in encrypted form may be unrecoverable for reasons that include loss of passwords and unavailability of suitable decryption software. Loss of passwords may be by human error (long-term lack of message passing) or loss of password vaults (software or systems in which passwords are securely stored). 

Some passive controls will live outside the user interface and may not be apparent to day-to-day operators. For example, HIT systems typically need to exhibit resiliency in their architecture whether brought about through redundancy or other systematic means. These design features represent active engineered controls. However it is common for this to be supported by other more passive controls which require some degree of human intervention. The platforms on which systems reside can often be monitored for availability and performance. In some cases systems may be specifically instrumented to provide metrics on the execution of specific functions or the success of database transactions. Similarly systems may log errors or failed messages which are then made available for inspection by service management personnel.
