Hrbacek
2010 Journal of Logic and Analysis  
two formulations of relative set theory.  ...  In Péraire [22] and the author's [14, 15, 16] , relative set theory is formulated as a first-order theory in the language with equality and two binary predicate symbols, ∈  ...  There are two important reasons for expanding relative set theory to a theory of external sets.  ...

Relative set theory: Internal view

Hrbacek
2009 Journal of Logic and Analysis  
Theories with many levels solve this problem in a simple, natural way. Some of these issues are discussed in detail in [16] .  ...  This paper is concerned with metamathematics of internal relative set theories.  ...  This is one reason why we need to address the issue of extendibility of GRIST to a theory of external sets. There are also foundational reasons.  ...

Foundations for a Theory of Gravitation Theories

Kip S. Thorne, David L. Lee, Alan P. Lightman
1973 Physical Review D, Particles and fields  
A foundation is laid for future analyses of gravitation theories. This foundation is applicable to any theory formulated in terms of geometric objects defined on a 4-dimensional spacetime manifold.  ...  The foundation consists of (i) a glossary of fundamental concepts; (ii) a theorem that delineates the overlap between Lagrangian-based theories and metric theories; (iii) a conjecture (due to Schiff) that  ...  [Example -General Relativity (Table II) with an initial coordinate system xa(0), produces a new coordinate system [Example -General Relativity (Table II) : a kpt is any set of functions I[go(x) = gcr  ...

Category Theory with Stratified Set Theory [article]

Thomas Forster, Adam Lewicki, Alice Vidrine
2019 arXiv   pre-print
This paper examines the category theory of stratified set theory (NF and KF).  ...  Such a development leads one to consider the appropriate notion of "elementary topos" for stratified set theories.  ...  We already know strongly cantorian sets support coequalisers of morphisms between them, but we can now strengthen this result. Theorem 39.  ...

Theory and External Validity

J. G. Lynch
1999 Journal of the Academy of Marketing Science  
[this issue]) proposes that external validity concerns require more attention in theoretical research.  ...  The author proposes "friendly amendments" to Winer's three proposals to pursue a better understanding of external validity through theory.  ...  For the theorist, the key issue is that unanticipated failures of external validity provide evidence that the theory lacks construct (nomological) validity; the theory is wrong.  ...

Identity Theory and Personality Theory: Mutual Relevance

Sheldon Stryker
2007 Journal of Personality  
A most important respect in which the two differ is in the attention paid to the social structural settings, small and large, within which social interaction takes place.  ...  The heart of the present essay provides reviews of Identity Theory and the structural symbolic interactionist frame from which Identity Theory derives.  ...  The variations develop from alternative stances taken with regard to a set of issues important to how the frame can be and is used in applications.  ...

Minimalist theory: The least theory that practice requires

M Scriven
1998 American Journal of Evaluation  
The first provides a general discussion of the nature of theories-and the reasons why some understanding of this abstract subject is of value in the practice of evaluation.  ...  Note that prediction is just a bonus, not a necessary condition for something to be a theory, even a good theory, and there are many respectable disciplines, from geology to history, where the best theories  ...  Minimalist theory begins by addressing the demarcation issue. But it goes on to set out a core doctrine about the nature and content of evaluation.  ...

Self-Determination Theory [chapter]

Edward L. Deci, Richard M. Ryan
2015 International Encyclopedia of the Social & Behavioral Sciences  
Self-determination Theory (SDT) is a motivational theory of personality, development, and social processes that examines how social contexts and individual differences facilitate different types of motivation  ...  In this, one sees that some types of extrinsic motivation (identified and integrated) are relatively autonomous along with intrinsic motivation and one type of internal motivation (introjected) is relatively  ...  Many current theories, such as the social cognitive and social learning theories (e.g., Bandura, 1996) fall somewhere between the ends of the continuum with some aspects of the theories reflecting somewhat  ...

Motivation Crowding Theory

Bruno S. Frey, Reto Jegen
2001 Journal of economic surveys (Print)  
Crowding effects thus are an empirically relevant phenomenon, which can, in specific cases, even dominate the traditional relative price effect.  ...  The Motivation Crowding Effect suggests that external intervention via monetary incentives or punishments may undermine, and under different identifiable conditions strengthen, intrinsic motivation.  ...  been accepted at the theoretical level, but the theory is also disputed by some scholars.  ...
