These seeds are metaphors for voice or words: to spread voice, words, and opinion to an audience. In a scientific context, dissemination is defined as making projects results available to the scientific community, policy makers and industry – using scientific language prioritizing accuracy. [ 1 ]
Mass communication is "the process by which a person, group of people or organization creates a message and transmits it through some type of medium to a large, anonymous, heterogeneous audience." [ 2 ] This implies that the audience of mass communication is mostly made up of different cultures and behavior and belief systems .
After identifying a message, or part of a message, to be linguistically encoded, a speaker must select the individual words—also known as lexical items—to represent that message. This process is called lexical selection. The words are selected based on their meaning, which in linguistics is called semantic information. Lexical selection ...
CDMA is a spread-spectrum multiple-access technique. A spread-spectrum technique spreads the bandwidth of the data uniformly for the same transmitted power. A spreading code is a pseudo-random code in the time domain that has a narrow ambiguity function in the frequency domain, unlike other narrow pulse codes. In CDMA a locally generated code ...
In a binary direct-sequence system, each chip is typically a rectangular pulse of +1 or −1 amplitude, which is multiplied by a data sequence (similarly +1 or −1 representing the message bits) and by a carrier waveform to make the transmitted signal. The chips are therefore just the bit sequence out of the code generator; they are called ...
In this model, information is stored as nodes clustered with related nodes by associated pathways. If one node is activated, nearby nodes are also activated. This is known as spreading activation. Priming occurs when a node is activated, causing related nodes to stand by for possible activation. Both the intensity and amount of elapsed time ...
In a 1998 review, Paul Marsden suggested that social contagion is a similar phenomena to memetics, a field of study inspired by Richard Dawkins' 1976 book The Selfish Gene. Marsden suggested that the two fields could be complementary, in the sense that work on social contagion largely lacked a coherent theory, but contained much evidence based ...
The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end.
