Body formations of therapist and couple during therapy sessions mainly function to signal their degree of readiness to interact or their degree of engagement in the therapeutic process, which is one contextual display of their affective communication. For this study, we developed the Body Formation Coding System (BFCS), a 4-category instrument to assess engagement at the triadic level. This article presents the BFSC method as well as a first validation on a sample of 14 triads. The results show that (a) triads vary according to their degree of triadic engagement; (b) engagement is related to the degree of therapeutic alliance; and (c) when the alliance is sufficient, a triadic invariant of engagement emerges. This means that partners regulate and coordinate their behaviors to maintain a stable level of engagement, whatever changes in their conversational organization. Finally, it discusses the potential of this method for describing the interactive aspects of the therapeutic alliance.

We observed mutual smiling episodes (MSEs) during therapist-couple triadic interaction as a key element of affective exchanges that serve to regulate the therapeutic relationship. Based on a functional perspective, we developed a new rating scale, the MSE Coding System (MSE-CS) that allows us to distinguish between four different MSEs, which correspond to four social functions: supporting mutual binding, sharing miseries, repairing, and confronting. MSEs were analyzed in a sample of eight therapist-couple triads. Therapeutic alliance and marital adjustment were also measured. The instrument (MSE-CS) demonstrated satisfactory inter-rater reliability, and initial indications of validity are promising. Results showed that number of MSEs was positively correlated with triadic therapeutic alliance. Types of MSEs were also distributed differently depending on the level of triadic therapeutic alliance.

Abstract. The time domain is the emerging forefront of astronomical research with new facilities and instruments providing unprecedented amounts of data on the temporal behavior of astrophysical populations. Dealing with the size and complexity of this requires new techniques and methodologies. Quasars are an ideal work set for developing and applying these: they vary in a detectable but not easily quantifiable manner whose physical origins are poorly understood. In this paper, we will review how quasars are identified by their variability and how these techniques can be improved, what physical insights into their variability can be gained from studying extreme examples of variability, and what approaches can be taken to increase the number of quasars known. These will demonstrate how astroinformatics is essential to discovering and understanding this important population.
