Embodied interaction : language and body in the material world
\"How do people organize their body movement and talk when they interact with one another in the material world? How do they coordinate linguistic structures with bodily resources (such as gaze and gesture) to bring about coherent and intelligible courses of action? How are physical settings, artifacts, technologies, and non-linguistic sign-systems implicated in social interaction and shared cognition? This volume brings together advanced work by leading international scholars who share video-based research methods that integrate semiotic, linguistic, sociological, anthropological, and cognitive science perspectives with detailed, microanalytic observations. Collectively they provide a coherent framework for analyzing the production of meaning and the organization of social interaction in the complex and heterogeneous settings that are characteristic of modern life: ranging from ordinary and bilingual conversation to family interaction, and from daycare centers to work settings such as airplanes, clinics, and architects' offices, and to activities such as auctions and musical performances. Several chapters investigate how participants with communicative impairments (aphasia, blindness, deafness) creatively build meaning with others. Embodied Interaction is indispensable for anyone interested in the study of language and social interaction. This volume will be a point of reference for future research on multimodality in human communication and action\"--Provided by publisher.
Handover patterns: an observational study of critical care physicians
Background Handover (or 'handoff') is the exchange of information between health professionals that accompanies the transfer of patient care. This process can result in adverse events. Handover 'best practices', with emphasis on standardization, have been widely promoted. However, these recommendations are based mostly on expert opinion and research on medical trainees. By examining handover communication of experienced physicians, we aim to inform future research, education and quality improvement. Thus, our objective is to describe handover communication patterns used by attending critical care physicians in an academic centre and to compare them with currently popular, standardized schemes for handover communication. Methods Prospective, observational study using video recording in an academic intensive care unit in Ontario, Canada. Forty individual patient handovers were randomly selected out of 10 end-of-week handover sessions of attending physicians. Two coders independently reviewed handover transcripts documenting elements of three communication schemes: SBAR ( S ituation, B ackground, A ssessment, R ecommendations); SOAP ( S ubjective, O bjective, A ssessment, P lan); and a standard medical admission note. Frequency and extent of questions asked by incoming physicians were measured as well. Analysis consisted of descriptive statistics. Results Mean (± standard deviation) duration of patient-specific handovers was 2 min 58 sec (± 57 sec). The majority of handovers' content consisted of recent and current patient status. The remainder included physicians' interpretations and advice. Questions posed by the incoming physicians accounted for 5.8% (± 3.9%) of the handovers' content. Elements of all three standardized communication schemes appeared repeatedly throughout the handover dialogs with no consistent pattern. For example, blocks of SOAP's Assessment appeared 5.2 (± 3.0) times in patient handovers; they followed Objective blocks in only 45.9% of the opportunities and preceded Plan in just 21.8%. Certain communication elements were occasionally absent. For example, SBAR's Recommendation and admission note information about the patient's Past Medical History were absent from 22 (55.0%) and 20 (50.0%), respectively, of patient handovers. Conclusions Clinical handover practice of faculty-level critical care physicians did not conform to any of the three predefined structuring schemes. Further research is needed to examine whether alternative approaches to handover communication can be identified and to identify features of high-quality handover communication.
Built Space and the Interactional Framing of Experience during a Murder Interrogation
Human interaction and communication involve space in multiple ways. This paper examines the spatial and interactional order of a covertly video-taped police interrogation. When the participants enter the interrogation room and become engaged in the interrogation process, the room itself is a constraint and a resource for interaction. While interacting within a built environment, the participants appropriate their material surroundings in ways that constitute a spatial order and make possible certain arguments. This paper examines how the physical structure of the interrogation room is differentially appropriated, used, and filled in by the participants' territorial and postural manoeuvers over the course of their interaction; and how the spatial structures thus created by the bodily appropriation of the physical locale are subsequently formulated by talk and thereby used as a metaphorical resource to frame the participants' situated experience. Through this embedded process, the interrogators move the suspect toward confession.
Arguing and thinking errors: cognitive distortion as a members' category in sex offender group therapy talk
Sexual offending remains a serious social problem. Because of significant psychological repercussions for many victims and the high rates of offender recidivism, there is a pressing need for research on the effective treatment of sex offenders (Johnston and Ward, 1996). The most common form of intervention consists of cognitive-behavioural therapy incorporating concepts of relapse prevention (Murphy and Smith, 1996). Typical targets of treatment are aspects implicated in the origins and maintenance of sexual offending: offenders' deviant sexual preferences, their lack of empathy for victims, and cognitive distortions (Marshall, 1999). In this chapter, we present discursive research on the treatment of offenders' cognitive distortions.Cognitive distortions represent one facet of problematic cognitive processes theorised to underpin offenders' criminal behaviour; denial or minimisation of sexual offences, problematic attitudes toward women and children, and crime-supportive attitudes have also been identified (Marshall, 1999). Abel and his colleagues (e.g., Abel et al., 1984, 1989) employed the term ‘cognitive distortions’ to describe those offence-relevant beliefs of child molesters that serve to justify and maintain their conduct. The literature suggests that offenders support sexist beliefs about women, likely view children in sexualised terms and endorse attitudes supportive of the sexual entitlement of males (Ward et al., 1997). Clinicians and researchers stress the importance of such distorted thinking and maladaptive beliefs in the facilitation or justification of sexual offences (Johnston and Ward, 1996). Cognitive-behavioural therapy assumes that, in order for sex offenders to alter their behaviour, they must change the way they think.
Considering the Social and Material Surround: Toward Microethnographic Understandings of Nonverbal Communication
Nonverbal communication occurs naturally and necessarily within a social and material environment. When people gesture with their hands, for example, they usually talk to someone at the same time, coordinating their visible and vocal behaviors to be understood altogether (e.g., Schegloff, 1984). Hands (and other nonverbal behaviors) occupy and move within three-dimensional spaces that include physical objects and structures, and our gestures may be largely recognized and understood through their relationship to the material world within reach (e.g., Goodwin, 1997, 2000b; Heath & Hindmarsh, 2000; LeBaron & Streeck, 2000).
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 (\\(\\mathrm{D}\\approx31\\) Mpc), from \\(<1\\) to 180 days after explosion. The high-cadence observations of SN 2022xkq, a photometrically transitional and spectroscopically 91bg-like SN Ia, cover the first days and weeks following explosion which are critical to distinguishing between explosion scenarios. The early light curve of SN 2022xkq has a red early color and exhibits a flux excess which is more prominent in redder bands; this is the first time such a feature has been seen in a transitional/91bg-like SN Ia. We also present 92 optical and 19 near-infrared (NIR) spectra, beginning 0.4 days after explosion in the optical and 2.6 days after explosion in the NIR. SN 2022xkq exhibits a long-lived C I 1.0693 \\(\\mu\\)m feature which persists until 5 days post-maximum. We also detect C II \\(\\lambda\\)6580 in the pre-maximum optical spectra. These lines are evidence for unburnt carbon that is difficult to reconcile with the double detonation of a sub-Chandrasekhar mass white dwarf. No existing explosion model can fully explain the photometric and spectroscopic dataset of SN 2022xkq, but the considerable breadth of the observations is ideal for furthering our understanding of the processes which produce faint SNe Ia.
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875. Extensive spectroscopic coverage reveals an early hot (T >= 40,000 K) continuum and carbon features observed \\(\\sim\\)1~day after discovery, SN Ic-like photospheric-phase spectra, and strong forbidden calcium emission starting 38 days after discovery. SN 2022oqm has a relatively high peak luminosity (MB = -17 mag) for (CaRTs), making it an outlier in the population. We determine that three power sources are necessary to explain the light curve (LC), with each corresponding to a distinct peak. The first peak is powered by an expanding blackbody with a power law luminosity, suggesting shock cooling by circumstellar material (CSM). Subsequent LC evolution is powered by a double radioactive decay model, consistent with two sources of photons diffusing through optically thick ejecta. From the LC, we derive an ejecta mass and 56Ni mass of ~0.6 solar masses and ~0.09 solar masses. Spectroscopic modeling suggests 0.6 solar masses of ejecta, and with well-mixed Fe-peak elements throughout. We discuss several physical origins for SN 2022oqm and find either a surprisingly massive white dwarf progenitor or a peculiar stripped envelope model could explain SN 2022oqm. A stripped envelope explosion inside a dense, hydrogen- and helium-poor CSM, akin to SNe Icn, but with a large 56Ni mass and small CSM mass could explain SN 2022oqm. Alternatively, helium detonation on an unexpectedly massive white dwarf could also explain SN 2022oqm.
