Reference Evaluation: A Three-Step Approach—Surveys, Unobtrusive Observations, and Focus Groups

Some Two–Step and Three–Step Nilpotent Lie Groups with Small Automorphism Groups

We construct examples of two-step and three-step nilpotent Lie groups whose automorphism groups are “small” in the sense of either not having a dense orbit for the action on the Lie group, or being nilpotent (the latter being stronger). From the results we also get new examples of compact manifolds covered by two-step simply connected nilpotent Lie groups which do not admit Anosov automorphisms...

Teaching English Pragmatics in an EFL Context: Effects of Obtrusive and Unobtrusive Focus on Form Instructions

With the aim of more emphasis on pragmatics and its inclusion in EFL classrooms, this study attempted to investigate the effectiveness of obtrusive and unobtrusive focus on form instructions on learners’ pragmatic performance of criticizing in English. 54 Iranian learners, all at intermediate level, participated in this study, and they were divided into three groups: 19 participants receiving o...

Focus groups.

This paper introduces focus group methodology and discusses its relevance to those researching health care provision. As a qualitative data collection technique, the focus group has advantages over other qualitative methods, such as the in-depth interview and nominal group technique. This paper highlights these advantages after providing guidelines on group composition, the management of group ...
