Temporal indeterminacy, the lack of specific knowledge about the timing of events, occurs often in temporal reasoning in practical applications and is connected to the concept of time granularity. Although logical properties of granularities have been described by several researchers in the literature, the implications of temporal indeterminacy and granularities for probabilistic representation...

A variety of methods for computing factor scores can be found in the psychological literature. These methods grew out of a historic debate regarding the indeterminate nature of the common factor model. Unfortunately, most researchers are unaware of the indeterminacy issue and the problems associated with a number of the factor scoring procedures. This article reviews the history and nature of f...

Valid-time indeterminacy is “don’t know when” indeterminacy, coping with cases in which one does not exactly know when a fact holds in the modeled reality. In this paper, we first propose a reference representation (data model and algebra) in which all possible temporal scenarios induced by valid-time indeterminacy can be extensionally modeled. We then specify a family of sixteen more compact r...

This paper presents a consistent theory for describing indeterminacy and uncertainty of 3-D reconstruction from a sequence of images. First, we present a group-theoretical analysis of gauge transformations and gauges by invoking the Lie group theory. We then discuss how to evaluate the reliability of the solution that has indeterminacy. We also extend the Cramer-Rao lower bound to problems with...

This report reexamines experimentally the problem of competitive indeterminacy in mixed-species populations of the flour beetles, Tribolium confusum and T. castaneum. Indeterminacy takes the form of alternative competitive outcomes: in some replicate cultures one species exterminates the other with a probability, say p, whereas in others, the opposing species wins with a complementary probabili...

1. E.J. Lowe claims that quantum physics provides examples of ontic indeterminacy, of vagueness in the world. Any such claim must confront the Evans-Salmon argument to the effect that the notion of ontic indeterminacy is simply incoherent (Evans 1978, Salmon 1981: 243-46). Lowe argues that a standard version of the Evans-Salmon argument fails quite generally (Lowe 1994). Harold Noonan (1995) ha...

This article discusses the perceptual phenomenon of visual indeterminacy in an art historical and scientific context and considers its role in certain heightened states of awareness. Further philosophical implications of the phenomenon are discussed, specifically the suggestion that visual indeterminacy may point to an inherent contradiction in the relationship between mind and world. This disc...

Houshang Golshiri is among the Iranian leading creative and imaginative fiction writers who managed to open up new horizons in Iranian fiction. Hence he could be claimed to be an innovative avant-garde short story writer with unique stylistic characteristics. Although inspired by fiction writers such as Alavi, Sadeqi, Golestan and Sa'edi in the techniques of narration, Golshiri nonetheless stan...

In endogenous growth theory models exist which are characterized by local and global indeterminacy. These concepts imply that economies differ with respect to their growth rates on the transition path (local indeterminacy) as well as their long−run growth rates (global indeterminacy). While the empirical density function of the levels of aggregate GDP has been the subject of a great many studie...
