SEARCH FOR A "GRAVITOID" THEORY [PDF]

open access: yesInternational Journal of Modern Physics A, 2003
By combining the concepts of graviton and matroid, we outline a new gravitational theory which we call gravitoid theory. The idea of this theory emerged as an attempt to link the mathematical structure of matroid theory with M theory. Our observations are essentially based on the formulation of matroid bundle due to MacPherson and Anderson–Davis. Also,

An Analysis of Theories of Search and Search Behavior [PDF]

open access: yesProceedings of the 2015 International Conference on The Theory of Information Retrieval, 2015
Theories of search and search behavior can be used to glean insights and generate hypotheses about how people interact with retrieval systems. This paper examines three such theories, the long standing Information Foraging Theory, along with the more recently proposed Search Economic Theory and the Interactive Probability Ranking Principle. Our goal is

Minimizing the expected search time of finding the hidden object by maximizing the discount effort reward search

open access: yesJournal of Taibah University for Science, 2020
A new search technique is developed to locate the hidden target (object) in one of the N-disjoint regions that are not identical. The lost object follows a bivariate distribution. Minimizing the search effort with discount reward has been applied instead

In Search of a Feminist Theory of Expression

open access: yesNordic Wittgenstein Review, 2022
In the Tractactus Logico Philosophicus, Wittgenstein concludes that what cannot be spoken about is better left unsaid, which would correspond to everything that is not scientific language susceptible of being formalized in the propositional framework ...

Towards a theory of search queries [PDF]

open access: yesProceedings of the 12th International Conference on Database Theory, 2009
The need to manage diverse information sources has triggered the rise of very loosely structured data models, known as dataspace models. Such information management systems must allow querying in simple ways, mostly by a form of searching. Motivated by these developments, we propose a theory of search queries in a general model of dataspaces.

In search of a theory of debt management [PDF]

open access: yesJournal of Monetary Economics, 2010
A growing literature integrates theories of debt management into models of optimal fiscal policy. One promising theory argues that the composition of government debt should be chosen so that fluctuations in the market value of debt offset changes in expected future deficits.

Perspective-Taking: In Search of a Theory

open access: yesVision, 2020
Perspective-taking has been one of the central concerns of work on social attention and developmental psychology for the past 60 years. Despite its prominence, there is no formal description of what it means to represent another’s viewpoint.
