Intersubjectivity at the counter: Artefacts and multimodal interaction in theatre box office encounters
The present study investigates the interplay between language, material and embodied resources in one specific type of service encounters: interactions at theatre box offices. The data consist of video recorded interactions in Swedish at three box offices, two in Sweden and one in Finland. Cases representative of the interactions are selected for a multimodal micro-analysis of the customer seller interactions involving-artefacts from the institutional and personal domain.The study specifically aims at advancing our understanding of the role of artefacts for structuring and facilitating communicative events in (institutional) interaction. In this way, it contributes to the growing research interest in the interactional importance of the material world. Our results show that mutual interactional focus is reached through mutual gaze in strategic moments, such as formulation of the reason for the visit. Artefacts are central in enhancing intersubjectivity and mutual focus in that they effectively invite the participants for negotiation, for example, about a seating plan which can be made visually accessible in different ways. Verbal language can be sparse and deictic in these moments while gaze and pointing to an artefact does more specific referential work. Artefacts are also a resource for signalling interactional inaccessibility, the seller orienting to the computer in order to progress a request and the customer orienting to a personal belonging (like a bag) to mirror and accept such a temporary non-accessibility. We also observe that speech can be paced to match the deployment of an artefact so that a focal verbal item is produced without competing, simultaneous physical activity. (C) 2016 The Authors.

Evidence For Genetic Heterogeneity Between Clinical Subtypes of Bipolar Disorder
We performed a genome-wide association study of 6447 bipolar disorder (BD) cases and 12 639 controls from the International Cohort Collection for Bipolar Disorder (ICCBD). Meta-analysis was performed with prior results from the Psychiatric Genomics Consortium Bipolar Group for a combined sample of 13 902 cases and 19 279 controls. We identified eight genome-wide
significant, associated regions, including a novel associated region on chromosome 10 (rs10884920; P = 3.28 × 10 − 8) that includes the brain-enriched cytoskeleton protein adducin 3 (ADD3), a non-coding RNA, and a neuropeptide-specific aminopeptidase P
(XPNPEP1). Our large sample size allowed us to test the heritability and genetic correlation of BD subtypes and investigate their genetic overlap with schizophrenia (SCZ) and major depressive disorder. We found a significant difference in heritability of the two
most common forms of BD (BD I h2 = 0.35; BD II h2 = 0.25; P = 0.02) with a genetic correlation between BD I and BD II of 0.78,compared with a genetic correlation of 0.97 when BD cohorts containing both types were compared. In addition, we demonstrated a significantly greater load of polygenic risk alleles for SCZ and BD in patients with BD I compared with patients with BD II, and a
greater load of SCZ risk alleles in the bipolar type of schizoaffective disorder (SAB) compared with both other BD subtypes. These results point to a partial difference in genetic architecture of BD subtypes, and are suggestive of a molecular correlate for the

Copy number variation in bipolar disorder.
Large (>100 kb), rare (500 kb) CNVs in BD compared with SZ, most notably for deletions >1 Mb (P=9 × 10(-4))
