BACKGROUND The growing interest in the effects of contextual environments on health outcomes has focused attention on the strengths and weaknesses of alternate contextual unit definitions for use in multilevel analysis. The present research examined three methods to define contextual units for a sample of children already enrolled in a respiratory health study. The Inclusive Equal Weights Metho...

The purpose of this study was to investigate the effect of two strategies of explicit teaching of economic terms on learners' vocabulary learning and retention. In the first explicit strategy, known as 'etymological elaboration', the focus was on presenting conceptual metaphors through 'identify-the-source' tasks, that is, providing the learners with the source domains underlying the metaphors,...

In this doctoral thesis, we apply premises of cognitive linguistics to terminological definitions and present a proposal called the flexible terminological definition. This consists of a set of definitions of the same concept made up of a general definition (in this case, one encompassing the entire environmental domain) along with additional definitions describing the concept from the perspect...

An important approach for efficient inference in probabilistic graphical models exploits symmetries among objects in the domain. Symmetric variables (states) are collapsed into meta-variables (metastates) and inference algorithms are run over the lifted graphical model instead of the flat one. Our paper extends existing definitions of symmetry by introducing the novel notion of contextual symme...

Implementations of concurrent objects should guarantee linearizability and a progress property such as wait-freedom, lock-freedom, obstruction-freedom, starvation-freedom, or deadlock-freedom. Conventional informal or semi-formal definitions of these progress properties describe conditions under which a method call is guaranteed to complete, but it is unclear how these definitions can be utiliz...

The present study aimed to examine and compare the impact of teaching economic terms through etymological elaboration with three more conventional methods of vocabulary instruction in ESP courses in Iran, that is, teaching through contextual definitions, L1 translation, and implicit instruction on the learners' general comprehension of economic texts and their understanding of author's opinion....

The paper deals with principles and properties of single frequency networks of digital television and radio transmitters. Basic definitions and contextual relationships (guard interval, area of SFN, influence of used modulation parameters etc.) are explained.

A contextual semantics – defined in terms of successful termination and mayand shouldconvergence – is analyzed in the synchronous pi-calculus with replication and a constant Stop to denote success. The contextual ordering is analyzed, some nontrivial process equivalences are proved, and proof tools for showing contextual equivalences are provided. Among them are a context lemma and new notions ...
