An overview of the question-response system in American English conversation

This article, part of a 10 language comparative project on question–response sequences, discusses these sequences in American English conversation. The data are video-taped spontaneous naturally occurring conversations involving two to five adults. Relying on these data I document the basic distributional patterns of types of questions asked (polar, Q-word or alternative as well as sub-types), types of social actions implemented by these questions (e.g., repair initiations, requests for confirmation, offers or requests for information), and types of responses (e.g., repetitional answers or yes/no tokens). I show that declarative questions are used more commonly in conversation than would be suspected by traditional grammars of English and questions are used for a wider range of functions than grammars would suggest. Finally, this article offers distributional support for the idea that responses that are better “fitted” with the question are preferred

Introduction: Multimodal interaction

That human social interaction involves the intertwined cooperation of different modalities is uncontroversial. Researchers in several allied fields have, however, only recently begun to document the precise ways in which talk, gesture, gaze, and aspects of the material surround are brought together to form coherent courses of action. The papers in this volume are attempts to develop this line of inquiry. Although the authors draw on a range of analytic, theoretical, and methodological traditions (conversation analysis, ethnography, distributed cognition, and workplace studies), all are concerned to explore and illuminate the inherently multimodal character of social interaction. Recent studies, including those collected in this volume, suggest that different modalities work together not only to elaborate the semantic content of talk but also to constitute coherent courses of action. In this introduction we present evidence for this position. We begin by reviewing some select literature focusing primarily on communicative functions and interactive organizations of specific modalities before turning to consider the integration of distinct modalities in interaction

Parent resistance to physicians' treatment recommendations: One resource for initiating a negotiation of the treatment decision

This article examines pediatrician-parent interaction in the context of acute pediatric encounters for children with upper respiratory infections. Parents and physicians orient to treatment recommendations as normatively requiring parent acceptance for physicians to close the activity. Through acceptance, withholding of acceptance, or active resistance, parents have resources with which to negotiate for a treatment outcome that is in line with their own wants. This article offers evidence that even in acute care, shared decision making not only occurs but, through normative constraints, is mandated for parents and physicians to reach accord in the treatment decision

Stance, alignment, and affiliation during storytelling: When nodding is a token of affiliation

Through stories, tellers communicate their stance toward what they are reporting. Story recipients rely on different interactional resources to display alignment with the telling activity and affiliation with the teller's stance. In this article, I examine the communication resources participants to tellings rely on to manage displays of alignment and affiliation during the telling. The primary finding is that whereas vocal continuers simply align with the activity in progress, nods also claim access to the teller's stance toward the events (whether directly or indirectly). In mid-telling, when a recipient nods, she or he claims to have access to the teller's stance toward the event being reported, which in turn conveys preliminary affiliation with the teller's position and that the story is on track toward preferred uptake at story completion. Thus, the concepts of structural alignment and social affiliation are separate interactional issues and are managed by different response tokens in the mid-telling sequential environment

Modified repeats: One method for asserting primary rights from second position

In this article I examine one practice speakers have for confirming when confirmation was not otherwise relevant. The practice involves a speaker repeating an assertion previously made by another speaker in modified form with stress on the copula/auxiliary. I argue that these modified repeats work to undermine the first speaker's default ownership and rights over the claim and instead assert the primacy of the second speaker's rights to make the statement. Two types of modified repeats are identified: partial and full. Although both involve competing for primacy of the claim, they occur in distinct sequential environments: The former are generally positioned after a first claim was epistemically downgraded, whereas the latter are positioned following initial claims that were offered straightforwardly, without downgrading

Non-antibiotic treatment recommendations: Delivery formats and implications for parent resistance

This study draws on a database of 570 community-based acute pediatric encounters in the USA and uses conversation analysis as a methodology to identify two formats physicians use to recommend non-antibiotic treatment in acute pediatric care (using a subset of 309 cases): recommendations for particular treatment (e.g., “I’m gonna give her some cough medicine.”) and recommendations against particular treatment (e.g., “She doesn’t need any antibiotics.”). The findings are that the presentation of a specific affirmative recommendation for treatment is less likely to engender parent resistance to a non-antibiotic treatment recommendation than a recommendation against particular treatment even if the physician later offers a recommendation for particular treatment. It is suggested that physicians who provide a specific positive treatment recommendation followed by a negative recommendation are most likely to attain parent alignment and acceptance when recommending a non-antibiotic treatment for a viral upper respiratory illness

Evidence on the Economics of Equity Return Volatility Clustering

The underlying economic sources of volatility clustering in asset returns remain a puzzle in financial economics. Using daily equity returns, we study variation in the volatility relation between the conditional variance of individual firm returns and yesterday's market return shock. We find a number of regularities in this market-to-firm volatility relation. (1) It decreases following macroeconomic news announcements; (2) it does not change systematically during the high-news months when firms announce quarterly earnings; and (3) it increases substantially with our measures of dispersion-in-beliefs across traders about the market's common-factor signal. Our evidence suggests that volatility-clustering is a natural result of a price formation process with heterogeneous beliefs across traders, and that volatility clustering is not attributable to an autocorrelated news-generation process around public information such as macroeconomic news releases or firms' earnings releases. We find consistent results in our sample of large-capitalization firms in Japan and the U.K., which suggests a generality of our results and bolsters our economic interpretation.

A Preliminary Report on \u3cem\u3eEscherichia coli\u3c/em\u3e Strain Diversity in Cows

Pyroprinting is a strain typing method that relies on the simultaneous pyrosequencing of the multi-copy rRNA intergenic transcribed spacer regions of E. coli (Black, et al., 2014). These pyroprints can be used to identify the source of E. coli in the environment. Currently, Cal Poly’s Center for Applications in Biotechnology (CAB) is augmenting the existing E. coli pyroprint library. By pyroprinting the intestinal E. coli of cows, we can quantify the strain diversity present, evaluate persistence, and determine the minimum sample size required for a complete overview of the cow intestinal E. coli population. These pyroprints can then be added to the current pyroprint library to be used for comparison to environmental samples. 504 unique pyroprints from two cows were generated over the course of this study, and from these, we determined that the sample size necessary to capture all of the diversity present in a cow at any given time would be over 300 isolates. The intestinal E. coli population of a cow is almost perfectly even, with most strains only being represented by one or two isolates. There is low persistence between sampling events, and very little transmission between cows. These data suggest that intestinal E. coli diversity in cows will be difficult to completely capture, and is not a prudent use of the CAB’s time or money

A preference for progressivity in interaction

This article investigates two types of preference organization in interaction: in response to a question that selects a next speaker in multi-party interaction, the preference for answers over non-answer responses as a category of a response; and the preference for selected next speakers to respond. It is asserted that the turn allocation rule specified by Sacks, Schegloff & Jefferson (1974) which states that a response is relevant by the selected next speaker at the transition relevance place is affected by these two preferences once beyond a normal transition space. It is argued that a “second-order” organization is present such that interactants prioritize a preference for answers over a preference for a response by the selected next speaker. This analysis reveals an observable preference for progressivity in interaction
