Going to the zoo

Abstract

This paper reports on an investigation of gaze patterns and other non-verbal behavior in dyadic, problem-solving based interactions. In a planning activity, participants are given an instruction sheet and a physical map of a zoo. Both participants must coordinate their actions to find a common solution to the problem. This paper aims at examining how activity-based interactions vary from other interactions, such as everyday conversation and story-telling (Goodwin 1980; Bavelas et al. 2002, 2007). The findings of this paper suggest that participants’ non-verbal behavior, such as smiling, nodding and in particular gaze, varies according to the interactional organization. In egalitarian interactions gaze directed at the other person occurs together with meta-task utterances, for example personal and humorous remarks. This paper highlights the role of gaze in task-based interactions to show that gaze is an integral part of stance taking, as it enables participants to position themselves in a joint activity.

Weak lensing by the large scale structure in a spatially anisotropic universe: Theory and predictions

“…We advocate that their measurements in future surveys such as Euclid and SKA, on scales where the linear regime holds, can set strong constraints on the anisotropy. The amplitude for these two surveys is estimated in our companion article [70].…”

“…A numerical analysis of some simple anisotropic phenomenological models, together with observational constraints from Euclid [71] and SKA [72] surveys, will appear in a companion paper [70].…”

“…We provide all the technical tools (perturbation theory, light propagation, expression of the observables). The application of our formalism is exposed in our companion paper [70] in which we compute the expected signals for the Euclid [71] and SKA [72] observations. Among our main results, we emphasize that, as soon as local isotropy does not hold at the background level, there exist a series of weak-lensing observables that allow one to fully reconstruct the background shear and thus test spatial isotropy.…”
