Unsure what to do with all your awareness? For those working on a cause they care about, the first instinct is often to make sure that as many people as possible are aware of the problem.
Increased mobility was made possible by a revolution in communications.
In the earlier 18th century long-distance travel was rare and the idea of long-distance travel for pleasure was a contradiction in terms. The speediest coach journey between London and Cambridge just 60 miles took… Models of communication Fragmentation and problems of interdisciplinary outlook have generated a wide range of discussion concerning the ways in which communication occurs and the processes it entails.
Obviously, all the critical elements in this question may be interpreted differently by scholars and writers in different disciplines. The simplicity of their model, its clarity, and its surface generality proved attractive to many students of communication in a number of disciplines, although it is neither the only model of the communication process extant nor is it universally accepted.
As originally conceived, the model contained five elements—an information source, a transmittera channel of transmission, a receiverand a destination—all arranged in linear order.
Messages electronic messages, initially were supposed to travel along this path, to be changed into electric energy by the transmitter, and to be reconstituted into intelligible language by the receiver. In time, the five elements of the model were renamed so as to specify components for other types of communication transmitted in various manners.
The information source was split into its components both source and message to provide a wider range of applicability.
The six constituents of the revised model are 1 a source, 2 an encoder3 a message, 4 a channel, 5 a decoder, and 6 a receiver. For some communication systems, the components are as simple to specify as, for instance, 1 a person on a landline telephone, 2 the mouthpiece of the telephone, 3 the words spoken, 4 the electrical wires along which the words now electrical impulses travel, 5 the earpiece of another telephone, and 6 the mind of the listener.
In other communication systems, the components are more difficult to isolate—e. Begging a multitude of psychological, aestheticand sociological questions concerning the exact nature of each component, the linear model appeared, from the commonsense perspective, at least, to explain in general terms the ways in which certain classes of communication occurred.
It did not indicate the reason for the inability of certain communications—obvious in daily life—to fit its neat paradigm.
Entropynegative entropy, and redundancy Another concept, first called by Shannon a noise source but later associated with the notion of entropy a principle derived from physicswas imposed upon the communication model.
Entropy is analogous in most communication to audio or visual static—that is, to outside influences that diminish the integrity of the communication and, possibly, distort the message for the receiver.
Negative entropy may also occur in instances in which incomplete or blurred messages are nevertheless received intact, either because of the ability of the receiver to fill in missing details or to recognize, despite distortion or a paucity of information, both the intent and content of the communication.
Although rarely shown on diagrammatic models of this version of the communication process, redundancy —the repetition of elements within a message that prevents the failure of communication of information—is the greatest antidote to entropy.
Most written and spoken languages, for example, are roughly half-redundant. If 50 percent of the words of this article were taken away at random, there would still remain an intelligible—although somewhat peculiar—essay.
Similarly, if one-half of the words of a radio news commentator are heard, the broadcast can usually be understood.
Redundancy is apparently involved in most human activities, and, because it helps to overcome the various forms of entropy that tend to turn intelligible messages into unintelligible ones including psychological entropy on the part of the receiverit is an indispensable element for effective communication.
Messages are therefore susceptible to considerable modification and mediation. Entropy distorts, while negative entropy and redundancy clarify; as each occurs differentially in the communication process, the chances of the message being received and correctly understood vary.Numerical ice sheet models are used to understand the driving forces behind changes observed in ice sheets and to predict future ice sheet behaviour.
Supervision Models Process And Practices Social Work Essay Introduction. Supervision process is constructed in a way both a recipient and provider can benefit from the process, it is an opportunity to reflect and develop supervisory practice.

At this stage we were still hunter-gatherers, out looking for food rather than growing and rearing our own supplies.
Modern day hunter-gatherers such as the San of Namibia and Botswana, still acquire about 60% of their energy intake from meat and milk.
