Manifest functions are the consequences that people see, observe or even expect. It is explicitly stated and understood by the participants in the relevant action. The manifest function of a rain dance, according to Merton in his 1957 Social Theory and Social Structure, is to produce rain, and this outcome is intended and desired by people participating in the ritual.
The manifest variables in factor analysis and latent profile analysis are continuous and in most cases, their conditional distribution given the latent variables is assumed to be normal. In latent trait analysis and latent class analysis, the manifest variables are discrete. These variables could be dichotomous, ordinal or nominal variables.
In distinguishing between manifest and latent functions, Merton argued that one must dig to discover latent functions. His example from his 1949 piece, "Manifest and Latent Functions", was an analysis of political machines. Manifest and latent functions were devised to prelude the inadvertent confusion between conscious motivations for social ...
Latent-variable methodology is used in many branches of medicine. A class of problems that naturally lend themselves to latent variables approaches are longitudinal studies where the time scale (e.g. age of participant or time since study baseline) is not synchronized with the trait being studied. For such studies, an unobserved time scale that ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.
[12] [10] Shannon and Weaver hold that models of communication should provide good responses to all three problems, ideally by showing how to make communication more accurate and efficient. [10] The prime focus of their model is the technical level, which concerns the issue of how to accurately reproduce a message from one location to another ...
Electronically mediated communication often happens asynchronously in that the participants do not communicate concurrently. Examples include email [3] and bulletin-board systems, where participants send or post messages at different times than they read them. The term "asynchronous communication" acquired currency in the field of online ...
