     View Summary

    As part of emergency medicine, prehospital care is provided to seriously sick or injured patients who need treatment before they are transferred to a hospital. A flight doctor and a flight nurse normally administer prehospital care to these patients by flying to a rendezvous point to which an ambulance crew brings the patient. Flight doctors and flight nurses must work within various constraints differing from those they face in their usual work in a hospital Emergency Medical Unit in terms of staff numbers, devices for testing, and types of medicine. However, it is not easy for them to learn the competences involved in the practical management of prehospital care through socialization as only a limited number of individuals can fly in a helicopter. Our study aims at presenting the competences of flight nurses that are involved in the practical management of prehospital care activities through examining moment-by-moment interaction among a flight doctor, a flight nurse, and emergency crew members. By examining what is known to the members at each moment, including what is taken for granted by the members and thus not explicitly expressed in words but nevertheless known to them, we intend to present another way of approaching issues of interprofessional collaboration in health care settings.

  • Social distribution of knowledge in action: The practical management of classification

    Ikeya N., Sharrock W., Relevance and Irrelevance: Theories, Factors and Challenges, 2018.09

     View Summary

    In this paper we attempt to revisit the concept of social distribution of knowledge Alfred Schutz once put forward to be the central concept in sociology of knowledge, operationalising this in the context of practical action. In doing so, we examine how the notion of relevance is deployed as the members' practical concern in the context of librarianship. Thus, this is an attempt to look into activities where members not only operate under auspices of organised stocks of knowledge, but also modify the organisation of those stocks of knowledge as needed in their attempts to accomplish their work. Examination of librarians making books available to users through classification in a university library in the U.K. revealed that their activities involve their management of professional and organisational corpuses of knowledge, in this case, through the medium of classification schemes. Librarians in the university studied were using the "local version" of the DDC (the Dewey Decimal Classification), and were adapting it to the needs of the library service as they saw them. The notion of "relevance" extensively informs their work, two dimensions of relevance being prominent. The librarians understand their work to be responsive to the varying and changing requirements of users, their decisions being shaped to provide what they construe as "what readers want". The other significant relevance we considered is that of aligning the library's classification with the relational features of academic and scientific fields as embedded in documented "subject matters". Thus, relating the stocks of library materials to the current shape of the professional corpus in domains of knowledge so that it stays relevant to collectivity members seems to be central to the community, and what the relevance consists of may vary depending on the community.

     View Summary

    The achievement of topical relevance to the parties of the research is a common aim in qualitative approaches in the social sciences, and ethnomethodology is no exception. Har- old Garfinkel sought to realise this aim by introducing the notion of hybridity, with which he attempted to merge the topic of ethnomethodological studies with the investigative topic treated by members in the field. While he is known to have set a high standard for researchers, particularly in terms of the unique adequacy requirement, there are cases of hybridisation of studies that provided practical value to the practitioners, indicating that they were of topical relevance to them. Thus, while ethnomethodological principles have been mostly discussed in methodological arguments for producing adequate descriptions, this paper explores the principles in the context of hybridisation of studies in practice. First, the paper examines Garfinkel’s arguments on hybrid studies of work as a radical restatement of principles of ethnomethodological studies; second, it examines a case of hybridisation of a hybrid study of emergency control to show the distinctiveness of his solution to the issue of topical relevance to the parties. The examination demonstrates how hybridisation of studies with the specific audience/reader’s corpus of knowledge is carried out within the constraints of the study, within which the presentation is embedded. It also demonstrates how the hybridity of hybrid studies achieved through collaboration between ethnomethodology and emergency control is treated as the basis of its hybridisation with management, including both demonstrations of descriptions of work and suggestions made by the researcher. These demonstrations will reveal how policies of ethnomethodo- logical studies are critical to the hybridisation of hybrid studies.

    © 2019 Association for Computing Machinery. All rights reserved. This workshop is aimed at bringing together a multidisciplinary group to discuss Machine Learning and its application in the workplace as a practical, everyday work matter. It's our hope this is a step toward helping us design better technology and user experiences to support the accomplishment of that work, while paying attention to workplace context. Despite advancement and investment in Machine Learning (ML) business applications, understanding workers in these work contexts have received little attention. As this category experiences dramatic growth, it's important to better understand the role that workers play, both individually and collaboratively, in a workplace where the output of prediction and machine learning is becoming pervasive. There is a closing window of opportunity to investigate this topic as it proceeds toward ubiquity. CSCW and HCI offer concepts, tools and methodologies to better understand and build for this future.

     View Summary

    In air medical services, prehospital care is provided within a short period of time by the air medical team, which consists of a small number of people, i.e., a doctor and a nurse who fly to the site and a few ambulance crews who drive to the site. Under circumstances that are different from hospitals and with limited resources and expertise, the flight nurse is normally expected to take the initiative to manage the entire process of providing care to the patient eventually transported to a hospital, which involves decision-making coordinated mainly with the doctor and ambulance crews. While a number of studies have attempted to identify what is required of a flight nurse to effectively work on site, the approaches taken in those studies mostly rely on interview methods and questionnaire (Stohler 1998; Pugh et al. 2002) rather than examining actual practices.

    In this paper, we examine the actual practices of the flight nurse who works as part of the air medical team by examining video data of prehospital care provided as part of air medical services in Japan (the so-called “Doctor-Helicopter”). In the data, the flight nurse’s view via a small portable camera in the breast pocket is available. We also conducted interviews with flight nurses to analyze the data.

    As a result, we found that the concept of “projection” developed in the study of ordinary conversation seems to be relevant for characterizing the flight nurse’s work (Sacks et al. 1974; Streeck 1995). The nurse attempts to provide other team members with projectability of the situation at each stage by providing a candidate item that needs consideration or a candidate task which needs to be carried out. This allows individual team members to see what to do next, and how to coordinate with each other in actually deciding what to do, and how to do the task. Thus, we will demonstrate that the nurse’s taking the initiative to effectively coordinate activities with other members can be described in terms of making the situation projectable in the course of providing care to the patient.

  • Revisiting the EMCA way of studying organizational culture and practices

    Symposium, workshop panel (public)

     View Summary

    EMCA studies conducted in organizational settings have sought to provide for how members conduct their work under the auspices of ‘organizationally located corpuses’ (Sudnow 1965; Zimmerman 1969; Sacks 1997). Organizationally located corpuses include both systematized as well as unsystematized bodies of information, understandings, organizationally certified knowledges and their associated practices of use. While conducted under their auspices, activities are not carried out solely with regards to these organizationally located corpuses. Rather, these occasioned corpuses (Zimmerman and Pollner 1970) – available to participants in particular situations and assembled in and through the courses of activities which characterize them – are mutually constituted as specific both to their “here and now” but also to what is known to the participants before they enter any particular working situation. The latter may include corpuses not necessarily located in, provided for or produced as part of the specific organizational setting, e.g., knowledge of how to proceed with a conversation or send an email, but made relevant to it.

    By looking at how members proceed with their work in this way, EMCA studies can be regarded as providing descriptions of organizational cultures and their constitutive practices. This position is not always understood. For instance, EMCA studies have been cast as overly preoccupied with contingency and with defending a ‘libertarian’, ‘anything goes’ view of cultural structures (Alexander et al 2012). However, EMCA studies should be understood as attempts to show how ‘structures’ are exhibited in particular working situations and how they are interwoven with the ways in which members organize their own activities. In other words, EMCA studies can be regarded as examinations of “structures” in action, rather than “structures” on their own. This orientation makes it possible to show how “structures” are reproducibly related to particular actions. Further, by closely looking into how order is organized in and as part of activities, the studies allow readers to learn what and how “cultural colleagues” (Garfinkel 1967: 11) find “structures” in and as part of particular settings.
