The paradox from within: research participants doing-being-observed

This article analyses a collection of cases from video recordings of naturally occurring interaction in institutional settings, where members display an orientation to the presence of the recording equipment. Such instances have been treated elsewhere as evidence of contamination of the ecology of the setting. The findings suggest that participants do remain aware of the recording activity, but that they publicly display when they are attending to it. Indeed, it is used as one resource to occasion identity work as competent, knowledgeable members of a particular institutional community, displaying to one another their understanding of the research aims, and their knowledge of how these kinds of data are constituted. Investigating how observational research is oriented to and constituted by the observed allows for a better understanding of what at that moment and in that setting is deemed recording-appropriate or -inappropriate conduct, and offers a more nuanced perspective on how data are co-constituted

THE PHYSIOPATHOLOGY OF BREATH‐HOLDING ATTACKS: A HYPOTHESIS

A physiopathological mechanism for the occurrence of breath‐holding attacks in children is postulated. This suggests that under certain stresses a child forcibly expires and squeezes deoxygenated blood out of the right side of his heart, through a patent foramen ovale into the systemic circulation. This deoxygenated blood causes cyanosis. A fall in cardiac output gives rise to cerebral anoxia, unconsciousness, and in some instances, fits. In the so‐called pallid attacks, much the same sequence of events occurs, but in this instance the foramen ovale is closed and therefore cyanosis cannot occur and the child faints due to transient cardiac arrest.
