Abstract: Emergency situations demand fast, effective multi-agency collaboration.
Communication is crucial, but often difficult under immense time pressure, in extremely complex
and often very dangerous settings. This paper explores the role of embodied conduct and
movement in making sense of the changing situation and in coordinating emergency teamwork. It
presents ethnographic observations with emergency service professionals during training
exercises for major incidents and ethnomethodological analysis.
Key words: embodied conduct, motion, coordination, emergency teamwork
1. Introduction
Gesture research has always recognised the interdependence of language, embodied conduct and
the material environment in social encounters (Kendon, 1976; Lebaron, & Streeck, 1997;
Goodwin, 2003). But for the most part, researchers have concentrated on 'focused encounters'
(Goffman, 1961) where small groups of participants are oriented towards each other and their
environment. Larger scale, more peripheral and multi-participant aspects of the role of embodied
conduct have only infrequently come under scrutiny – most notably at airports (Goodwin, &
Goodwin, 1996), in control rooms (Heath, & Luff, 1992), and museums (vom Lehn et al., 2001).
The study at hand contributes to this line of inquiry by examining interaction in the context of
emergency response training exercises. Detailed analysis of data from video recorded participant
observation during the one hour on site part of a training exercise in Aarhus, Denmark, shows
that people's movements and embodied conduct, and the movement of victims and equipment is
socially organised and a crucial resource for coordinating the large scale and fast paced
coordination of work that is required
Figure 1: Video stills from start to end of the on site part of the exercise. Names of staff have
been changed and the faces of 'victims' have been blurred to safeguard anonymity.
In the exercise scenario a school-bus has collided with a train carrying hazardous chemicals. A
group of emergency training officers have staged this collision at the harbour. They call 112, the
number used for all emergency calls in Denmark and notify the police. This is a 'live' exercise,
which means that the accident will be reported as real on the online police system, which is
integrated with communication systems in emergency control and dispatch centres, fire stations
and hospitals nationwide. The exercise is meant to test and train the readiness of regular on duty
personnel, and it is soon correctly classed as a major incident, which means that several different
agencies will be involved. Within seconds the first members of an eventually over 30 persons
strong team arrive: three police officers, a fire crew, and an ambulance with two paramedics. A
medical team, a second fire crew and a crew of 'incident assistants' arrive later. Eight school
children are trapped on the bus, some (made up to look) severely injured. It soon becomes clear
that this is not a real incident, but an exercise. Nevertheless, most of the personnel take the
situation very seriously.
The seriousness and realism of exercises like this reflects the difficulty of achieving a
coordinated response across different agencies and locations. On the incident site, police, fire
services, and medical personnel need to continuously assess the situation, secure the scene, create
access routes and ensure they are kept free; categorise, treat and transport victims; handle
hazardous materials or deal with contamination; and coordinate work with colleagues in
emergency vehicles, dispatch centres, and hospitals. Each professional and each team must make
their own decisions and get urgent work underway, in a way that is sensitive to decisions and
activities elsewhere. Coordination is difficult, under immense time pressure, in complex, often
chaotic and dangerous settings. Exercises serve to test equipment and familiarise people with its
use and help staff to put training and emergency response plans into practice and thereby evaluate
their efficacy (Peterson, & Perry, 1999). But perhaps most importantly, exercises train people's
awareness and collaborative decision-making skills, to minimize response times and maximise
the appropriateness of the response.
Effective communication has been recognised as a key factor for awareness, collaboration and
decision making in emergencies and some key insights from research in this field will be
reviewed briefly in the next section. There is very little analysis of embodied conduct. Yet, a
close look at the first few minutes of the emergency personnel's response to the incident at
Aarhus harbour highlights the significance of embodied conduct and motion. An audio-visual
ethnographic report is provided in section three. The discussion in section four draws out some
key features of large scale, fast-paced, peripheral and multi-agency emergency teamwork.
2. Background
Most studies of emergency work focus on control centres, where emergency calls are received
and response teams are dispatched. Nevertheless, some important insights can be gleaned. In their
recent review, Pettersson et al. (2004), for example, highlight ambiguities, awareness and
economy as key features of emergency communication. They show that it can be difficult to
communicate and understand the exact location of an emergency. Moreover, judgements about
the seriousness of incidents and the availability of response teams must be made fast, and often
with inadequate and complexly interrelated information (see also Martin et al., 1997). To add to
the confusion, several different witnesses may report the same incident. The call takers, who may
be distributed across large control centres, must realise this quickly in order to avoid dispatching
duplicate resources to the same incident. Awareness is achieved through a range of sophisticated
verbal and non-verbal means, many of which are intricately tied to material resources (e.g.
screens or maps) and the environment of the control centre. Heath, & Luff (1992), for example,
describe how talk, but also repeat embodied 'performances' (e.g. a worried, prolonged gaze at a
display board on the wall) are designed to draw attention to problems. Such almost theatrical,
exaggerated forms of embodied conduct may also serve to reach into the peripheral perceptual
fields of busy colleagues whose monitoring of activities around them must necessarily be cursory
(see also Heath, 1986, p. 72). Embodied behaviour is a crucial contributor to the 'economy' of
interaction aimed at achieving an appropriate emergency response efficiently and swiftly. It is
important to note that although researchers may describe talk and behaviour as designed and
economical, they also stress that hey are usually routine and 'automatic' rather than deliberately
planned and executed in these particular ways. ‘Fitness for purpose’ and economy are effects of
ordinary action. They evolve over time. People fine-tune their grasp of material affordances, and
their own and their fellows’ human capabilities through everyday, hands-on interaction with
tools, technologies, materials, environments and other people.
More recently, a few studies of emergency communication 'on the ground' have been published.
They focus almost exclusively on verbal communication. Dunn et al. (2002), for example,
examine data from training exercises around a chemical spill scenario, involving fire and rescue
service personnel. Rather than study the practical resolution of ambiguities, Dunn et al. posit that
the more information people are able to exchange, the better the chances for good decisions. They
argue that because communication takes time that could otherwise be spent on urgent tasks,
patterns of communication emerge that allow people to juggle talking about what should be done,
and doing it. Constant exchange strategies that are unaffected by the demands of the tasks at hand
seem to be more conducive of an appropriate response than patterns where communication is
more periodic. While Dunn et al. (2002)seem to suggest that work and talk, or responding and
coordinating are separate, almost incompatible activities, Landgren (2005, 2006) is more
sensitive to the way in which both, work and coordination, are achieved by and through talk. He
describes sense-making en route to a fire incident and maps out rhythms of talk during
mobilization, intervention, situational adjustment and incident completion. Landgren, too,
focuses on verbal communication as the primary tool for coordination, but also highlights the
'documentary' role of talk, not only with a view at the production of records after the event, but
also, and more importantly, with regards to the role that overhearing and seeing colleagues talk
plays in mutual awareness. On-site communication between different agencies and overhearing
are made difficult by noise and chaos as well as the use of different radio frequencies (Kristensen
et al., 2006), hampering coordination work done in and through talk. Landgren's ethnographic
approach (2006) is part of a technology design project, and his analysis informs the design of a
tool that seeks to provide an audio-visual 'map' of talk to emergency staff en route to, or already
on the site, which could be used to support awareness of ongoing work and decisions.
The study at hand is similarly motivated by a desire to inform the design of new technologies that
can support the work of emergency personnel. Together with several of the staff involved in the
exercise I am a member of an interdisciplinary team concerned with the design of ubiquitous and
mobile computing (PalCom). Our ethnographic work is ongoing and the results presented here
are exploratory in nature. Design ideas and implications are discussed elsewhere (Büscher and
Mogensen, submitted 2007, Kristensen, 2006), and will not be considered in this paper, in order
to give room to a discussion of emergency teamwork.
3. The study
While speed is of the essence in emergency situations, appropriateness of response ranks even
higher. Responsibility for an accurate threat assessment lies particularly heavily on the shoulders
of those arriving at the scene first (Perry, & Lindell, 2003). I have, therefore, chosen to examine
the opening few minutes of the harbour emergency exercise, to gain a sense of how first-on-the-
scene staff assess the situation and coordinat an appropriate response in practice.
Figure 2: A first threat assessment on arrival at the accident
Peter and Michael, two regular on duty paramedics, have been called to the accident at the
harbour (Figure 2). As they step out of the ambulance, they see a police officer looking at the
train as a fire fighter runs towards it, both also looking at them. Screams from the bus are muffled
by generator noise. Peter runs towards the fire fighter and the police officer. Although only one
side of this first coordination effort is on the video, we see that it is interactionally organised not
only through talk and the normal means of embodied orientation and gaze, but also in and
through motion.
Figure 3: Coordination in and through motion.
As Peter strides towards the police officer, the orientation of his body suggest that he is already
half on his way back (Figure 3). He is ready to put on the surgical gloves which re in his right
hand, making it obvious that he is keen to attend to victims on the bus. He asks 'is it safe?' and
before completion of the police officer's 'no, no', produced in overlap, Peter takes another stride
forward, and repeats the gesture. Movement and gesture question the police officer again, this
time without words, publicly documenting trouble in a noisy environment. Hearing part of an
explanation (inaudible to the observer) Peter echoes the 'no'. While looking at the police officer
who is still explaining, Peter co-produces the end of the explanation and starts to turn his back on
the police officer. He is now joined by his colleague, Michael, who saw the 'performance' of
trouble and now overhears the reasons for it.
However, that it is not safe to go in the bus takes a while to sink in. They are the first ambulance
to arrive on the scene, which means one of them has to act as the ambulance manager. In Figure
3, Michael is just putting on a vest that says 'ambulance manager'. They stop turning, step back,
look at the bus, at the train, at each other, begin to walk off in opposite directions, then – in mid
step – Michael changes direction, and follows Peter. For some seconds, it is evident that
confusion reigns (Figure 4).
Figure 4: Animation. Confusion reigns (here in slow motion).
Michael and Peter both return to the ambulance and get out helmets. They check briefly on two
children who have come out of the bus, but cannot begin transporting or treating victims until the
risk area and the nature of the threat from the chemical spill have been defined (a task led by the
fire brigade manager), they are drawn into participating in the threat assessment (Figure 5).
Figure 5: Multi-agency collaboration in threat assessment.
There is 'smoke' (created with dry ice) coming out from under the bus, blowing off to the back. It
looks like its source is on the other side of the railway carriage. Michael walks across to take
another look from a safe distance.
This is picked up by a passing fire fighter, who briefly mirrors the pose. It could be that the
paramedic has noticed something important. The fire fighter looks towards the police manager,
the other fire fighters and the fire brigade manager who are outside the video frame, and then
walks off, while the paramedic hesitates whether to take a closer look at the railway carriage.
Glancing to his left, Michael now sees the doctors' van arriving, and Lars, the fire brigade
manager, coming his way (Figure 6). He greets him: 'Good day Lars', but Lars does not return the
greeting. Instead he says 'There is a spill on the other side' and keeps walking.
Figure 6: Inspecting the source of the smoke. 'CORV' stands for 'Chemical and Organic Rescue Vehicle'.
So far, Lars has been told that the spill is of a dangerous acid. Later, as we will see, it turns out
that the level of danger requires breathing equipment. At this point, however, there is no way of
sensing that danger, which is why Lars and Michael approach without protective equipment.
Simulation of chemical (and radiological or biological) dangers is notoriously difficult. It is
virtually impossible to produce realistic symptoms (smells, colours, chemical reactions), let alone
simulate interaction with atmospheric and geographical forces. Lars and Michael rush to look at
the spill together (Figure 6). Michael's question about a Chemical and Organic Rescue Vehicle
emphasises the uncertainty about the nature of the chemical agent (and the intentions of the
exercise organisers). Part of their retreat is a collaborative gesture in motion. This gesture is,
again, a mirror production (Figure 7).
Figure 7: Michael reflects Lars' protective gesture.
Research in social psychology suggests that mirroring like this plays an important role in
establishing and documenting rapport (Lakin, 2003). Good rapport is of vital importance in
emergency situations, where many different actors need to work together – fast. Some of them,
like Michael and Lars, might know each other, but many will have never met before. Good
rapport also helps convey professionalism and efficiency – something that emergency services
are increasingly keen to communicate in the light of public criticism, for example about the
rivalries between police and fire units on 9/11 (National Commission, 2004).
Based mainly on laboratory experiments, social psychology shows that mirroring affects both, the
participants' ability to collaborate and observers' perceptions of their performance. However, the
question that is most interesting for sociological inquiry (and for the design of technologies to
support collaborative action) is not addressed. To understand mirroring one must ask how it is
achieved practically, and by looking closely at some key moments in this example, we can gain
some sense of this (Fig. 8).
Figure 8: Key moments within a frame-by-frame breakdown of the sequence of actions during an episode
of collaborative threat assessment.
As soon as Michael and Lars get to the other side of the railway carriage, their arms, hands, legs
and feet mirror, forming a position that is held for quite a while. They also mirror what they are
saying: 'It is this here' (Figure 8, 1&2). When Michael asks whether they have a Chemical and
Organic Rescue Vehicle, Lars does not answer but starts to end their inspection of the spillage
and this mirror position by dropping his hand (3). He lifts his right foot, and Michael, very
subtly, makes room for him to lead the way: while completing his utterance and holding his arm
outstretched, he moves his left leg back and turns ever so slightly (4).
To really make way, one would take a step back, but Michael stands, leaning slightly forward,
arms akimbo and the palm of his left hand (maybe also his right) pointing backwards (5), but
allowing Lars to pass and lead the way. A few steps later, Lars starts to shield Michael from
danger (6), while Michael turns his palm to reflect Lars's (Figure 9). It is hard to say whether
Michael anticipates Lars's conduct or whether Lars mirrors Michael.
Figure 9: Animation.
This collaborative sequence embodies professional skill, the delicate dovetailing of
responsibilities, and the lived assessment and awareness of danger. Analysis clearly shows that
mirroring is not something one person does mimicking another. The mirrored and the mirrorer
work together. In fact, the division of labour between mirrored and mirrorer might change, and
there are different modes of mirroring (Figure 10): imitating, anticipating, but also genuinely
reflecting other people's conduct.
Figure 10 : Imitating, anticipating, reflecting other people’s conduct.
But embodied conduct like this does not only echo other professionals' conduct, it also reflects
the 'conduct' of other important and potentially very active actors (e.g. victims whose medical
conditions change dramatically) and agents (e.g. a fire, chemical agents). Moreover, embodied
conduct documents agreements, disagreements and decisions about these actors and agents for
the participants in the interaction (see also Hindmarsh, & Pilnick, 2002), but also for a larger
audience. Embodied conduct is 'broadcast communication', and Lars and Michael's assessment
now propagates.
Their movement and gestures have formulated the spillage as dangerous with the range and
degree of danger as yet undetermined. Michael asks Peter to move the ambulance (Figure 11).
We are four minutes into the arrival of the first ambulance. The uncertainty about the spill is
holding up the rescue effort. Michael is pacing up and down. Until a rescue strategy is in place,
he and Peter cannot do anything. This is Lars' decision and he is on the radio now, providing a
status report for staff in the control centre, but also receiving further information about the
(intended) danger of the chemical spill. Michael sees and overhears this, walks backwards and
synchronises his movements with Lars', in effect 'catching' his attention (Figure 11).
While Lars is talking on the radio, Michael crouches down. Lars mirrors his movement. But
Michael is already getting up again, before he has reached the final crouching position. He
notices Lars’ mirroring and returns to a crouch. This also makes the passing fire man look in that
direction. Michael and Lars then part ways. While Lars walks over to his fire crew, giving them a
chance to overhear his communication with the control centre, Michael continues to pace up and
down, now eyeing the bus, now turning to see what is happening elsewhere, amongst other things
keeping an eye out for ‘huddles’.
The noise and chaos of the accident site that makes it difficult for the different agencies to share
information, together with the fragmented nature of radio communication underpin the frequent
formation of 'ecological huddles' (Goffman, 1961), where medical, police, rescue and fire brigade
managers share and review information and make decisions. Michael spots such a huddle (Figure
12) and joins it. A split second later, Lars approaches, too. He is finishing his call to the control
centre, when Peter and the medical team coordinator decide that they will request another four
ambulances, five altogether (note the hand gesture in Figure 12).
Figure 12 : Huddles form and important decisions are made and overheard.
The end of Lars' call (in Danish and hardly audible for the ethnographer) is overheard by all. He
has been told that the chemical spill is more dangerous than it seems and requires breathing
equipment. The end of his call now marks the start of on-the-ground decisions about the risk area
and the rescue operation (Figure 13). Michael anticipates the end of the call and walks ahead.
Lars walks towards the corner of the railway carriage, and turns to point at an area in the far
corner. This is where they should take and treat the injured. Peter reiterates that they have ordered
five ambulances to transport the injured off. Lars replies 'just a moment' and walks towards the
ambulance where he meets a fire fighter with a breathing mask and oxygen: they can begin to get
the injured out and transport them to the waiting area. These are 'symbiotic gestures', that is,
gestures that can only be understood in their relation to the environment and the activities at hand
(Goodwin, 2003), in this context including previous (overheard) conversations and (observed)
actions. In turn, the current talk and gestures renew and shape people's understanding of the
environment and the activities at hand. The actual risk area, the corridor for the rescue operation
and hand-over points emerge and are defined further through people's movements and actions
(Figure 14).
Soon, 'severely injured' children are being handed safely into the waiting area, where they can be
treated and prepared for transportation.
4. Discussion
Good coordination in multi-agency emergency response is not just a matter of the right person(s)
being in charge of a well organised command chain. As Quarantelli (1997) lucidly observes:
'control is not co-ordination'. Instead, coordination requires rich and dynamic awareness of a
changing situation and equally rich and dynamic mutual agreement on how to carry out tasks.
Emergency response practitioners and researchers recognise that communication is key to
successful coordination. However, current research has a bias towards control centres and verbal
communication and neglects important aspects of emergency work. The observations above show
clearly that embodied conduct and movement on the incident scene are socially organised and a
key resource for the social organisation of a well coordinated and appropriate emergency
response. Four issues seem particularly significant.
First, the way people move around on the incident site matters. Movement can attract attention
and reach into the peripheral field of colleagues whose attention may be focused elsewhere.
People may 'perform' trouble through movement, making it possible for others to expand their
'online' analysis of multimodal practices (Mondada, 2006) to large scale interaction. Attempts to
'scale up' mutual orientation to the social organisation of interaction is evidenced in the example
above by the fact that staff continuously try to take in more than the immediate focus of their
attention by moving around, pacing up and down, turning to see what is happening elsewhere.
While they may not always be able to overhear communication, they can often see roughly what
is being talked about and how it is perceived.
This raises the second issue - the 'broadcast' character of embodied conduct in motion. Social
interaction is 'scenic' (Jayyusi, 1988), and a short glimpse at Lars and Michael's collaborative
gesture in relation to the chemical spill, for example, would indicate that threat assessment is well
underway, and that one should stay away from there, while seeing a huddle of incident managers
may suggest the need to participate in the discussion. Thus the fact that ‘knowledge of the
environment undergoes continuous formation in the very course of [our] moving about in it’
(Ingold, 2000, pp. 226, 230) takes on a particular urgency in emergency situations. The
economies of interaction that have evolved here seem to rely on frequent, often repeated, very
pronounced (sometimes exaggerated, even theatrical) embodied conduct.
Third, the investigation of mirroring behaviour shows that 'rapport' is not just the result of some
inexplicable affinity between individuals. Also, it is more than a subconscious, almost reflex-like
response elicited through social-psychological stimulation. Mirroring requires fast and precise
local coordination, while being publicly visible. However, although clearly a collaboratively
organised phenomenon, the definition and sequential relation of moves and mirror moves are
fuzzy. Further analysis is necessary, but the observations above suggest that a reason for this
fuzziness is the degree of reflexivity in the interaction, and that this has a bearing on the practical
achievement of coordination. Conversational moves are reflexive, that is, each turn defines the
shape and status of the other, one prospectively, the other retrospectively (Mondada, 2006). Thus
questions are recognisable units that usually project answers, which through their timing and
shape reflexively confirm the status of the previous turn as a question. When mirroring, in
contrast, a person's first 'turn' (e.g. a palm facing backwards) may only become a noticeable 'unit'
by virtue of the fact that someone imitates or reflects it. Embodied interactional moves can thus
have far less definition, implicative force and 'direction' in terms of a next move than turns in
talk. In addition, next moves may be ambiguous even in regards to being meant as a next move.
Michael and Lars' collaborative threat assessment gesture, for example seems to develop through
extremely subtle interpretations of possibly physiologically automatic embodied conduct as
meaningful. The high degree of reflexivity, or mutually determining character, of such very
subtle (and very fast) movements requires heightened sensitivity to the other's body in relation to
its environment. As such, the gesture helps Michael and Lars achieve a mutually very sensitive
alignment.
Moreover, now turning to a fourth important issue, this alignment is publicly observable. This has
implications for our understanding of the decision making processes during emergency response.
It indicates not only collaborative, but joint (and bodily joined) sense making activity.
Synchronicity of movement thus not only creates a sense of mutual engagement. In many of the
examples above, people put themselves in a position where they can see what others are seeing.
Such publicly performed shared views of events document and produce a common
understanding. Against the backdrop of such a dynamically produced common understanding of
the situation it becomes obvious that decision-making is not just a matter of gathering and
making sense of predominantly verbal information. Decisions are collaboratively formulated
through talk, but also through embodied conduct and the movement of people and equipment in
relation to the material environment and the many actors and agents within it. They emerge. As
Lars and Michael demonstrate, shared understanding can be produced through and folded into
embodied conduct and movement to formulate and simultaneously display decisions over what is
being experienced: it is dangerous, I will provide, and I will accept protection. The latter aspect
amounts to a public production of a working division of labour. Through his willingness to accept
protection (which is one of the fire crew's main tasks) Michael also implicitly accepts potentially
negative consequences for his own task (e.g. a delay in the rescue operation). Such 'rapport'
greatly facilitates a coordinated response.
5. Conclusion
This paper presents an audio-visual ethnographic account of large scale, fast-paced, peripheral
and multi-agency emergency teamwork. Analysis focuses on the role of embodied conduct and
the practical achievement of a coordinated and appropriate response to an emergency staged for
a training exercise for regular on duty staff. The observations highlight that embodied conduct
and movement play a vital role in decision-making, the establishment of rapport, and the
dynamics of a shared understanding of events.

In this paper we describe the inspiration for, and the design of, prototype technologies that support emergency teamwork. We combine ethnographic studies of material practice, participatory design collaboration with emergency personnel, and knowledge of the potential of ubiquitous computing technologies to 'stretch' the materiality of envi-ronments, persons and equipment. A range of prototypes – products of an iterative, ethnographically informed, participatory design process – are described in a series of scenarios. We conclude with a discussion of potential benefits and challenges our experience raises for socio-technical-material innovation in emergency teamwork.

The “chameleon effect” refers to the tendency to adopt the postures, gestures, and mannerisms of interaction partners (Chartrand & Bargh, 1999). This type of mimicry occurs outside of conscious awareness, and without any intent to mimic or imitate. Empirical evidence suggests a bi-directional relationship between nonconscious mimicry on the one hand, and liking, rapport, and affiliation on the other. That is, nonconscious mimicry creates affiliation, and affiliation can be expressed through nonconscious mimicry. We argue that mimicry played an important role in human evolution. Initially, mimicry may have had survival value by helping humans communicate. We propose that the purpose of mimicry has now evolved to serve a social function. Nonconscious behavioral mimicry increases affiliation, which serves to foster relationships with others. We review current research in light of this proposed framework and suggest future areas of research.

*Research in this paper grows out of The Workplace Project, a collaborative research project devoted to the analysis of work as situated practice in multi- activity settings which was initiated by Lucy Suchman at Xerox PARC and funded by the Steelcase Corporation. Conversations with other members of the project — Françoise Brun-Cottan, Kathy Forbes, Gitti Jordan, Lucy Suchman and Randy Trigg—have deeply influenced our analysis. A very special debt is owed to Lucy Suchman for demonstrating to us the importance of including material settings in the analysis of human interaction and cognition as situated phenomena.

Despite technical advances over the past few years in the area of systems support for cooperative work there is still relatively little understanding of the organisation of collaborative activity in real world, technologically supported, work environments. Indeed, it has been suggested that the failure of various technological applications may derive from their relative insensitivity to ordinary work practice and situated conduct. In this paper we discuss the possibility of utilising recent developments within sociology, in particular the naturalistic analysis of organisational conduct and social interaction, as a basis for the design and development of tools and technologies to support collaborative work. Focussing on the Line Control Rooms in London Underground, a complex multimedia environment in transition, we begin to explicate the tacit work practices and procedures whereby personnel systematically communicate information to each other and coordinate a disparate collection of tasks and activities. The design implications of these empirical observations, both for Line Control Room and technologies to support cooperative work, are briefly discussed.

There is a prevailing assumption in the research literature that disaster exercises produce a wide variety of benefits that promote effective emergency management. Unfortunately, there are few studies available that confirm this assumption. This paper reviews the role of exercises in disaster management and places them within the context of preparedness activities. Within this context, the links among planning, training and exercising are explicated. The potential benefits of exercises are reviewed and hypotheses generated that link exercise experiences with emergency responders’ perceptions of planning adequacy, training adequacy, teamwork, response network effectiveness, equipment adequacy and job risk. The effects of two exercises – one dealing with hazardous materials and one with medical mass casualties – are examined using a quasi-experimental research design. The subjects were professional firefighters. Results indicated that successful exercises can enhance perceptions of teamwork, training adequacy, response network effectiveness, job risk, and equipment adequacy. The link between exercise participation and perception of planning adequacy was found to be equivocal.

Studies of talk-and-bodily-conduct-in-interaction have inspired new insights into the way in which language, interaction and cognition might be articulated. More particularly, they have shown that participants mutually orient to the finely tuned multimodal details by which talk and action in interaction are sequentially organized. This article deals with this form of ‘participants’ multimodal online analysis’ by focusing on a particular phenomenon - the methodical practices and resources by which the end of a turn and of an activity phase is projected and collectively achieved - in a specific videorecorded setting - a meeting in an architect’s office. It aims at questioning both how these local orientations are systematically displayed and exploited by the participants for the sequential organization of their activity and how they can be demonstrably observed by the analyst.

SUMMARY This study investigated the dynamics of communication between members of an emergency management team faced with controlling a hazardous chemical spill. The effects of two sets of factors on communication were investigated; task-specific factors pertaining to characteristics of the emergency management task that are constant across different emergency situations, and situation- specific factors pertaining to the unique characteristics of the current situation. The results showed that both these factors were important in determining the pattern of communication between key team members. Verbal exchanges were found both to be correlated with the occurrence of critical events and to follow a 30-minute temporal cycle. The implications of the results for theories of naturalistic decision making are discussed. Copyright # 2002 John Wiley & Sons, Ltd.
