What defines a school in scientific study?
A group sharing a common object, problem, methodology, gathering place, and thought current.
What is a paradigm in scientific knowledge?
An arrangement of knowledge based on a vision and way of seeing the scientific world.
What is a theory in scientific terms?
An organized set of concepts to think about or explain a phenomenon.
Who developed the theory of information?
Claude E. Shannon.
Who mentored Claude E. Shannon in developing information theory?
Warren Weaver.
Which theorists were associated with Shannon's information theory research?
Norbert Wiener and Alan Turing.
How does Shannon define communication?
All procedures by which one mind can influence another.
Which author defined communication as procedures for one mind to influence another?
Shannon.
How does the Shannon-Weaver model view communication?
As a system that can be statistically predicted.
What is the first step in the Shannon-Weaver communication process?
The source produces a message.
What role does the emitter play in the Shannon-Weaver model?
It encodes the message into signals.
What is the function of the channel in the Shannon-Weaver model?
It transports the signals.
Who reconstructs the message in the Shannon-Weaver model?
The receiver.
What is the destination in the Shannon-Weaver communication model?
The person to whom the message is sent.
What can disrupt signals during communication?
Noise.
What are the three important variables in mathematical communication?
Capacity of the channel, the code, and noise.
What is the central question in encoding messages for communication channels?
How to encode messages to maximize information through limited capacity channels considering noise.
What does the technical problem in communication address?
How accurately communication symbols can be transmitted.
What does the semantic problem in communication address?
How precisely symbols convey the intended meaning.
What does the effectiveness problem in communication address?
How effectively the received meaning influences conduct as desired.
Why should political communication choose channels according to message and audience?
To minimize information loss and anticipate transmission problems.
What does mathematical information measure in communication theory?
The diversity of choices in a repertoire of possible messages.
What is the key distinction of information in Shannon and Weaver’s theory?
It has a special technical sense distinct from everyday meaning.
How does common information differ from mathematical information?
Common information changes understanding; mathematical measures message choice diversity.
When does the value of information increase according to its probability?
When the probability of a message appearing is low.
What is the formula expressing informational value's relation to message probability?
Why is the mathematical theory of communication insufficient for human phenomena?
Because it excludes meaning, context, feedback, and element significance.
What does the mathematical theory of communication set aside?
Meaning, context or situation, feedback, and code and significance of elements.
What is feedback in communication?
Returning information that enables communicators to adapt.
In what historical context did the mathematical perspective emerge?
After the Second World War during a search for improved communication.
What was the main research focus of Turing, Weaver, and Shannon during WWII?
Decoding.
How did Turing, Weaver, and Shannon influence each other?
They conducted research during WWII and influenced one another.
What types of media can serve as a channel in communication?
Material or technical media like networks, paper, internet, posters, TV, space, coaxial cables, or optical fiber.
How might a political candidate select communication channels for people aged 18–25?
By using social media.
Why are logarithms used to measure information in Shannon’s theory?
To weight results and avoid overemphasizing the rarest messages.
Which analogy does Shannon use to explain weighting information values?
A Scrabble analogy.
