Admissibility in Finitely Generated Quasivarieties [PDF]

open access: yes, 2013
Checking the admissibility of quasiequations in a finitely generated (i.e., generated by a finite set of finite algebras) quasivariety Q amounts to checking validity in a suitable finite free algebra of the quasivariety, and is therefore decidable ...

Reducing Validity in Epistemic ATL to Validity in Epistemic CTL

open access: yes, 2013
We propose a validity preserving translation from a subset of epistemic Alternating-time Temporal Logic (ATL) to epistemic Computation Tree Logic (CTL). The considered subset of epistemic ATL is known to have the finite model property and decidable model-

Measuring time perspective in adolescents : can you get the right answer by asking the wrong questions? [PDF]

open access: yes, 2015
Time perspective continues to evolve as a psychological construct. The extant literature suggests that higher future orientation and lower present orientation are associated with better developmental outcomes. However, the extant literature also suggests

On Validity

open access: yesStudies in Applied Linguistics and TESOL, 2023
The way in which validity has been conceptualized has changed throughout the years. The focus in validation studies shifted from evaluating distinct components of validity to developing a comprehensive argument for the use and interpretations of test scores.

On Hopf's Lemma and the Strong Maximum Principle

open access: yes, 2005
In this paper we consider Hopf's Lemma and the Strong Maximum Principle for supersolutions to a class of non elliptic equations. In particular we prove a sufficient condition for the validity of Hopf's Lemma and of the Strong Maximum Principle and we ...

The Blazar Sequence: Validity and Predictions [PDF]

open access: yes, 2006
The "blazar sequence" posits that the most powerful BL Lacertae objects and flat-spectrum radio quasars should have relatively small synchrotron peak frequencies, nu_peak, and that the least powerful such objects should have the highest nu_peak values ...

Limits on the validity of the semiclassical theory [PDF]

open access: yes, 1995
For want of a more natural proposal, it is generally assumed that the back-reaction of a quantised matter field on a classical metric is given by the expectation value of its energy-momentum tensor, evaluated in a specified state.
