Fractal Nanotechnology

Self-similar patterns are frequently observed in Nature. Their reproduction is possible on a length scale 102–105 nm with lithographic methods, but seems impossible on the nanometer length scale. It is shown that this goal may be achieved via a multiplicative variant of the multi-spacer patterning technology, in this way permitting the controlled preparation of fractal surfaces

Multimodality and Gestures in the Teacher’s Communication

Abstract. The paper presents a research on the multimodal communication of teachers in the classroom. The “musical score”, a procedure for the analysis of multimodal communication, is used to analyse aspects of the signals produced and of the meanings conveyed by teachers while interacting with their pupils, by focusing not only on affective and interactional aspects, but also on the cognitive effects of nonverbal communication. Finally, the paper shows how, based on this procedure, it is possible to analyse chunks of teachers’ communication, and to distinguish different multimodal communicative styles among different teachers. 1 Multimodality in the Classroom Among studies on everyday interaction, an interesting area for the study of multimodal communication is teacher-pupil interaction, a topic generally studied in the domains of education, linguistics, sociolinguistics, pragmatics, and social psychology [1], [2], [3], [4]. [5] applied Ekman and Friesen’s analysis [6], mainly stressing the affective and interactional aspects of the teacher’s nonverba
