Elements and Principles of Demand Side Theory

Nov 15th version

Demand Side Information Theory


On the need to make clear distinctions

Demand side theory is based on a specific set of principles.  From demand side principles, quite different inferences are made about learning as compared with supply side. The nature of these differences must be understood before we start the development of a national demand side information infrastructure.  As proposed in the Resilience Project White Paper *<*> this national infrastructure may be supported by a federal program so that the tolls that would be placed if privatized will not control the public communication medium.  The argument here is not a socialist argument, it is an argument about the social value of establishing a better communication medium than what supply side capitalism has so far produced.  This is a philosophically challenging topic. 

A good illustration of principled differences is found in economics, where supply side economics may be compared with demand side economics.  However, the concept of demand side infrmation theory depends deeply on work in mathematical models of biological response mechanisms.  Of course, demand comes from the individual.  Biological response mechanisms provide a substrate for human communication.  A similar response mechanism may be designed into Internet sub-systems but this mechanism should be free of private ownership, for reasons that may be discussed. 

The emergance of phenomenon such as human language represents what may be a charateristic "stratified" architecture in natural systems.  This is a topic covered in Knowledge Foundations (Prueitt) *<*> where soem historical roots are exposed leading to the current proposed clean slate Internet specification.  The architecture uses self organization to create organizational scales in which the particular finds meaning as part of large processes. 

Demand side is more difficult to describe because causative forces are  distributed and involves many individuals. 

The issue of locality, non-locality and emergence within organizational stratum is considered by Prueitt to be the key to understanding why demand side and supply side have difficulty co-existing.  Because the two viewpoints have co-existence difficulty, and because supply side mechanisms are more primitive and easier to maintain, the supply side theory often inhibits demand side theory. This inhibition is seen in the form of polemics and mythology.  A multi-coherent viewpoint seems necessary to merge the two sides and to achieve a balance. 

The ideal is achieved when both supply side and demand side create equilibrium where symmetries induce a stability far from either one of the two extremes.  The creation of symmetry induction mechanisms is essential to transaction processing affording ask and bid economic transactions.  Perhaps the finanical crisis of October 2008 shows us the consequences of imbalance.  In order to maintain resilient markets, transactions must be transparent to both the large supply chains and to the internal demands arising from particular individuals.  Symmetry induction is also seen in perhaps any emergence of sub-structural aggregation to meet affording function, such as normal everyday biological function.  Substructural aggregation to meet the utility of functional demands is an induction from the particular to the universal, and is the central mechanism studied by second school advocates.  Specific examples from neurobiology are examined in a 1996 paper by Prueitt.  <*>

A second illustration may be seen in a comparison of various geometries, where the axiomatic foundation of these geometries are altered.  These different geometries have very different axiomatic spans, and can not be mixed in most cases. (One cannot assume both axioms forcing parallel lines to meet at infinite and parallel lines to not meet at infinite.) Likewise one has a set of deep assertions supporting supply side theory.  In some specific cases, these assertions may not be mixed with the assertions of demand side theory.  The two theories are "different" theories. 

The purpose of Prueitt's work is to define a new foundation for educational practice which may serve as an alternative to the current educational practice.  Thus, the distinctions between demand side and supply side must be kept clear, else the new work might be based, in error, on principles that are supply side in nature. 

For example, the use of computer aided tutorials is pure supply side as is the multiple choice test.  Both the problems and the answers are supplied.  Demand side requires the student to internalize an entire curriculum and then to manifest problems and answers, from within the individual.  see <*>

Of course, the current practice is not "pure" supply side, and the alternative is not "pure" demand side.  However, dynamical systems show that demand side and supply side do not easily co-exist and that the tendency is to evolve towards one foundation or the other. A similar situation exists with liberal and conservative governance.  The underlying dynamics has been modeled with neural network models.  In essence, the model's nature involves the emergence of a coherent field which then serves as an attractor region.  Interpretation is then baised by one side or the other. 

Demand side theory applies to all disciplines; religion, science as well as economics and information science. 

Beginning in 1985, Prueitt begin to find deep principles expressed in mathematical models using dynamical systems. Principles from both discrete and continuum dynamical systems were found as a means to understand specific failures in "current" educational theory.  As the work progressed, current theory was seen as almost purely supply side in nature.  The system supplies the student with the knowledge derived from the cultural heritage.  The mismatch between what the student might naturally "demand" creates a condition in which poor performance by the schools, K-12, leads to an acquired learning disability.  The learning mechanims become broken. 

Supply side theory is found in every academic discipline, including information science.  The work developed by Prueitt creates a principled basis for criticism of Shannon information theory and most computing theories as well as artificial intelligence and machine reasoning paradigms.  A demand side theory of information is realized in computing architecture, as proposed in non-public technical papers.  This theory is the basis for the proposed national Resilience Project.   <*>

Central Concepts

Demand side theory has the potential to provide a branding for any college that adopts this work.   Thus the work must remain pure in how what is represented is traced back to a set of central concepts.

Demand side core concepts collectively form a coherent paradigm.  The notion of a paradigm follows the classical work of Thomas Kuhn, and more recent works on explanatory coherence, such as those developed by Paul Thagard.  In Prueitt's work the notions of explanatory coherence are extended through his familiarity of the neural network research literatures, particularly those works focused on biologically feasible models of brain functioning. 

The central concepts include the following:

1) Cognition depends on several organizational stratum, each functioning under principles that are visible as elements of empirically verified natural science.

2)  Human cognitive expression depends on self image, e.g., self efficacy, and this self efficacy may either accelerate or inhibit learning.

3)  An Acquired Learning Disability may be shown to limit many students' capability and motivation. 

4)  ALD has both a social and a personal dimension. 

5)  It is possible to imagine a world where ALD does not exist.

6)  A specific demand side strategy may be designed to overcome ALD and to replace this disability with a clear understanding of the nature of mathematics.

7)  This strategy may be defined using the notion that the individual is unique in nature and is involved in creating universals from particular experiences.  The "induction" of universals from particulars involves self efficacy.  Thus the study of mathematics may become related to the study of self.

8) Topic mapping assists in internalizing the curriculum and thus in producing universals that reinforce a positive self efficacy and/or breaks down the acquired disability. 

9) Testing using topic based written expressions, e.g. blank paper tests, allows the individualization of learning, the development of positive self efficacy, and a focus on comprehension.
