Up to now, many studies have been done to show the origin of attitudes and their relationships with behaviors or actions. Some of those works have focused on students' attitudes and some have introduced the various contexts of language teaching and learning. These studies were enough to give a new impetus for conducting the present investigation. This paper investigated the teachers' attitudes ...

This volume collects the proceedings of the International and Interdisciplinary Conference on Modelling and Using Context, held in Rio de Janeiro in January 1997, which proved to be the first in a series. (The second was held in Trento in 1999, the third in Dundee in 2001.) The theory of context is important and problematic--problematic because the intuitions are confused, because of the dispar...

The aim: To explore the current context and main factors of public confidence in formal medicine. Materials methods: article is based on outcomes a cross-sectional survey designed to reflect varied dimensions individual/population’ perception healthcare services, namely: socio-demographic information, reflection individuals’ own health, services.

In this paper, we present a hybrid grammar formalism designed to learn structured models of natural iconic gesture performances that allow for compressed representation and robust recognition. We analyze a dataset of iconic gestures and show how the proposed Featurebased Stochastic Context-Free Grammar (FSCFG) can generalize over both structural and feature-based variations among different gest...

In this paper, a post-plus language is de.ned as a language which contains all the catenations of each word in the language with a proper su0x of this word. The set of all d-primitive words is a natural post-plus language. The family of all post-plus languages is a subfamily of all non-counting languages. Some basic properties and characterizations of post-plus languages are investigated. We ob...

Iterated hairpin completion is an operation on formal languages that is inspired by the hairpin formation in DNA biochemistry. Iterated hairpin completion of a word (or more precisely a singleton language) is always a context-sensitive language and for some words it is known to be non-context-free. However, it is unknown whether regularity of iterated hairpin completion of a given word is decid...
