corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...

All substantive areas of law with no exception have a common concern for the processes by which legal disputes get resolved. Naturally, the success of any particular litigation strategy in a legal dispute depends on a number of factors. Examples of influential factors are procedural costs, the judge’s accuracy and, most importantly, the litigation strategy followed by the counterpart in dispute...

The importance of balancing linguistic considerations, annotation practicalities, and end user needs in developing language annotation guidelines is discussed. Maintaining a clear view of the various goals and fostering collaboration and feedback across levels of annotation and between corpus creators and corpus users is helpful in determining this balance. Annotating non-canonical language bri...

ABSTRACT Information Technology enhances the possibility for people to communicate when separated in time and space. In Distance Education this means new tools for tutoring and collaboration. But what effects does IT have on the interaction between students and teachers? This paper presents results from an exploratory study of a distance education project at the University of Trollhättan Uddeva...

For an edge-bicolored graph G where each edge is colored either red or blue, a vertex set S is a dual feedback vertex set if S hits all blue cycles and red cycles of G. In this paper, we show that a dual feedback vertex set of size at most k can be found in time O∗(ck1) and all minimal dual feedback vertex set of size at most k can be enumerated in time O(c +k 2 ) by compact representations for...

A perceptual approach to generating features for use in indexing and retrieving images is described. Salient regions that immediately attract the eye are colour (textured) regions that usually dominate an image. Features derived from these will allow search for images that are similar perceptually. We compute colour features and Gabor colour texture features on regions identified from a coarse ...

A central finding in dialogue research is that interlocutors rapidly converge on referring expressions which become progressively contracted and abstract. However, there is currently no consensus on which mechanisms underpin convergence: The interactive alignment model (Pickering and Garrod) favours priming, the grounding model (Clark, 1996) prioritizes positive feedback, while Healey (2002) de...

The present paper presents a preliminary approach to the modeling of dynamic properties of the spatial assortment of alcohol outlets using agent-based techniques. Individual drinkers and business establishments are the core agent types. Drinkers assort themselves by frequenting establishments due to spatial and social (niche) motivations. We examine a number of questions concerning the feedback...

The known item search task (KIS) aims to retrieve a unique video or video clip in the video corpus. This paper presents a novel interactive video browsing system for KIS task. Our system integrates visual content-based, text-based and concept-based search approaches. It allows users to flexibly choose the search approaches. Moreover, two novel feedback schemes are employed: first, users can spe...
