2-(Benzylsulfanyl)pyridineN-oxide
2008
In the title compound, C12H11NOS, the dihedral angle between the oxopyridinium and phenyl rings is 58.40 (1)°. The crystal structure is stabilized by C—H...O hydrogen bonds, π–π stacking interactions involving the pyridinium rings [centroid–centroid distance = 3.6891 (9) Å] and C—H...π interactions.

Scanning and deep processing of information in hypertext: an eye tracking and cued retrospective think-aloud study
2016
When students solve problems on the Internet, they have to find a balance between quickly scanning large sections of information in web pages and deeply processing those that are relevant for the task. We studied how high school students articulate scanning and deeper processing of information while answering questions using a Wikipedia document, and how their reading comprehension skills and the question type interact with these processes. By analyzing retrospective think-aloud protocols and eye-tracking measures, we found that scanning of information led to poor hypertext comprehension, while deep processing of information produced better performance, especially in location questions. Thi…
Cueing complex animations: Does direction of attention foster learning processes?
2011
Abstract The time course of learners’ processing of a complex animation was studied using a dynamic diagram of a piano mechanism. Over successive repetitions of the material, two forms of cueing (standard colour cueing and anti-cueing) were administered either before or during the animated segment of the presentation. An uncued group and two other control conditions were also employed. Development of an internal representation of the movements depicted in the animation was evaluated through participant demonstrations of the mechanism’s operation on a replica piano mechanism. Eye tracking (fixation lengths) indicated that overall, conventional visuospatially-based cueing was largely ineffect…
Linguistic interpretation of speech errors
2016
The paper is an attempt to illustrate the linguistic interpretation of speech, known that it remains insufficiently resolved, especially for Romanian. The cause is given by the multitude of criteria that can or should be considered important in speech processing. The aim of this study is to develope a computational tool in order to identify the possible errors related to the morphosintactic structure of speech. Our goal is to assist users who can receive automatically different suggestions that can help them to improve the quality of their text. Thus, we chose an interdisciplinary approach through speech analysis that brings together the key fields of linguistics, computer science and so on…
Animated Corpses: Communicating with Post Mortals in an Anatomical Exhibition
2006
‘Plastinates’ (i.e. corpses conserved through plastics) are lab created artifacts which since the nineties have been the subject of a cultural field experiment via an anatomical exhibition. Similarly to brain-dead or digitalized bodies, they constitute an ambiguous form of post-mortem existence. The article inquires after the ways in which the ontological status of these entities is constituted through the practices of body donors, anatomists and visitors. Plastinates owe their ambiguity to an oscillation between two different frames of perception. Their meaning is determined by the extent to which an anatomy exhibition can impose a ‘medical gaze’ over a non-professional way of perception, …
Practices of grading: an ethnographic study of educational assessment
2013
The school as an institution assumes that students' grades are constituted by their assessments. This paper examines the background of this presupposition and provides a micro-analytical perspective of the grading practice of teachers in German High Schools (Gymnasium). This paper conceptualises the theoretical framework of the research in educational measurement in discussion. It is shown that the measured assessment of students and the teacher's observations are linked. When grading, teachers construct their own assessments. This process is depicted in this paper by two forms of observations: self-observation within the context of written examinations and third-party observation within th…
Studying social media as semiotic technology: a social semiotic multimodal framework
2018
How do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) m…
