We initiate the study of hedge connectivity of undirected graphs, motivated by dependent edge failures in real-world networks. In this model, edges are partitioned into groups called hedges that fail together. The hedge connectivity of a graph is the minimum number of hedges whose removal disconnects the graph. We give a polynomial-time approximation scheme and a quasi-polynomial exact algorith...

evidence occupies a paramount position in any logical endeavor and research article is consensually considered a predominant site of such an endeavor. one interesting area of rhetoric which addresses the source and reliability of evidence is quality metadiscourse. in this qualitative study, quality metadiscourse strategies (i.e., evidentials, hedges, boosters and disclaimers) are examined to in...

In so doing, 60 sales contracts were selected, 30 written by native English and 30 by Iranian non-natives. Based on Hyland and Tse’s taxonomy, the contracts were codified and classified in terms of the frequency and percentage of the interactiv...

Mentalizing has been examined both in autism spectrum disorder (ASD) and schizophrenia (SCZ) primarily by either cognitive-linguistic (referred to as verbal) or emotion recognition from eyes (referred to as visual) mentalizing tasks. Each type of task is thought to measure different aspects of mentalizing. Differences in clinical features and developmental courses of each disorder may predict d...

This contrastive study was conducted to contrastively analyze English and Farsi newspaper opinion columns in terms of the frequency of different types of stance markers.60 newspaper opinion columns (30 written in English and 30 written in Farsi) from 10 wide spread newspapers published in the United States and Iran in 2015 were analyzed.
