This chapter describes three general ways that participants arrive at a place where conversation stops. It first describes how the Sacks, Schegloff, and Jefferson turn-taking system produces lapses, and points out several deficiencies in the model. The analysis examines a range of situations and activities where conversation lapses, and divides them into three main types: lapses as the relevant cessation of talk, lapses as allowable silence, and lapses as the conspicuous absence of talk. In the course of the analysis and in the discussion, the chapter addresses the matter of gaps versus lapses, the importance of bodily conduct and activities, and the relationship of lapses to turn-taking and sequence organization.

News Interviews

ABSTRACTThe British news interview turn-taking system operates through a simple form of turn-type preallocation. This article shows that a large number of the systematic differences between the news interview and mundane conversation are a product of these constraints on the production of types of turns. It then explores the relationship of turn-type preallocation in news interviews to the background legal and institutional restrictions on British broadcast journalists. In so doing, it notes how the organisation of turn-taking in two other types of broadcast interview can differ from that in the news interview due to differences between the institutionalized footings that the interviewers are conventionally required to maintain within them.

The Relationship

Nonverbal turn taking, defined as back-and-forth exchanges, may be used to convey instrumental or social intent. It has been theorized that social turn taking is foundational to joint attention and, as such, it has been incorporated as a component of early interventions for children with autism, who often have challenges in joint attention competency. The purpose of this study was to analyze the relationships between two turn-taking functions and joint attention as observed during interactions between 20 toddlers with autism who received intervention and their caregivers. It was hypothesized that socially driven turn taking would be positively related to joint attention, but instrumentally motivated turn taking would not. Video analysis revealed a positive relationship between social turn taking and joint attention, but not between instrumental turn taking and joint attention. While not causal, the findings support the promotion of social content in intervention and the concept that social turn taking may be a precursory competency to joint attention. Lay abstract Back-and-forth interaction, or turn taking, may support later joint attention, a more complex form of interaction, when promoted in interventions for young children with autism, especially depending on the child’s intent when interacting. In the present study, we observed videos of 20 toddlers with autism engaging in turn taking with their caregivers during an intervention designed to support children’s joint attention. We sought to identify when the children displayed turn taking socially and when they were using it for nonsocial purposes in the intervention videos. We also observed videos after the intervention was complete to identify when children used joint attention when interacting with their caregivers. After these observations, we used these video data to explore the relationship of social turn taking to joint attention, and the relationship of nonsocial turn taking to joint attention. We found a significant relationship between social turn taking and joint attention, but not between nonsocial turn taking and joint attention. These findings support the importance of considering social turn taking in interactions between young children with autism and their caregivers.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Electron microscopy has proved to be an invaluable discipline in studies on the relationship of viruses to the origin of leukemia, sarcoma, and other types of tumors in animals and man. The successful cell-free transmission of leukemia and sarcoma in mice, rats, hamsters, and cats, interpreted as due to a virus or viruses, was proved to be due to a virus on the basis of electron microscope studies. These studies demonstrated that all the types of neoplasia in animals of the species examined are produced by a virus of certain characteristic morphological properties similar, if not identical, in the mode of development in all types of neoplasia in animals, as shown in Fig. 1.

The Relationship

In RBL-2H3 rat leukemic mast cells, crosslinking IgE-receptor complexes with anti-IgE antibody leads to degranulation. Receptor crosslinking also stimulates the redistribution of receptors on the cell surface, a process that can be observed by labeling the anti-IgE with 15 nm protein A-gold particles as described in Stump et al. (1989), followed by back-scattered electron imaging (BEI) in the scanning electron microscope. We report that anti-IgE binding stimulates the redistribution of IgE-receptor complexes at 37“C from a dispersed topography (singlets and doublets; S/D) to distributions dominated sequentially by short chains, small clusters and large aggregates of crosslinked receptors. These patterns can be observed (Figure 1), quantified (Figure 2) and analyzed statistically. Cells incubated with 1 μg/ml anti-IgE, a concentration that stimulates maximum net secretion, redistribute receptors as far as chains and small clusters during a 15 min incubation period. At 3 and 10 μg/ml anti-IgE, net secretion is reduced and the majority of receptors redistribute rapidly into clusters and large aggregates.

This report describes an unusual and persistent dysphonia in two young women who had taken a therapeutic regimen of isotretinoin for intractable acne. We report perceptual and instrumental data for their dysphonia, and pose a theoretical basis for the relationship of dysphonia to this drug. We also provide recommendations for reducing the risk of acquiring a dysphonia during the course of treatment with isotretinoin.
