Two hundred and forty nine 12 to 13 year old at-risk and not at-risk male and female high school students randomly selected from five high schools in the Perth metropolitan area of Western Australia provided self-reported delinquency data for three consecutive years. A multivariate analysis of variance revealed at-risk students self-reported significantly more involvement in delinquency at the first data collection point than their not at-risk counterparts. Male 12–13 year olds self-reported significantly more involvement in car related crimes, assault, rule infractions, and vandalism compared to their female peers. For some delinquent activities there were significant increases in involvement over time (Motor Vehicle, Drugs, and Public Disorder Offences) while for others (Theft, Rule Infractions, and Vandalism) this was not the case. In the majority of categories of delinquency at-risk students self reported significantly higher rates of involvement.

Purpose. To examine associations between environmental and lifestyle factors and overweight or obesity. Design. A cross-sectional survey and an environmental scan of recreational facilities. Setting. Metropolitan Perth, Western Australia. Subjects. Healthy sedentary workers and homemakers aged 18 to 59 years (n = 1803) living in areas within the top and bottom quintiles of social disadvantage. Measures. Four lifestyle factors, one social environmental factor, and five physical environment factors (three objectively measured). Results. After adjustment for demographic factors and other variables in the model, overweight was associated with living on a highway (odds ratio [OR], 4.24; 95% confidence interval [CI], 1.62–11.09) or streets with no sidewalks or sidewalks on one side only (OR, 1.35; 95% CI, 1.03–1.78) and perceiving no paths within walking distance (OR, 1.42; 95% CI, 1.08–1.86). Poor access to four or more recreational facilities (OR, 1.68; 95% CI, 1.11–2.55) and sidewalks (OR, 1.62; 95% CI, .98–2.68) and perceiving no shop within walking distance (OR, 1.84; 95% CI, 1.01–3.36) were associated with obesity. Conversely, access to a motor vehicle all the time was negatively associated with obesity (OR, .56; 95% CI, .32–.99). Watching 3 or more hours of television daily (ORs, 1.92 and 1.85, respectively) and rating oneself as less active than others (ORs, 1.66 and 4.05, respectively) were associated with both overweight and obesity. After adjustment for individual demographic factors and all other variables in the model, socioeconomic status of area of residence and leisure-time physical activity were not associated with overweight or obesity. Conclusion. Factors that influence overweight and obesity appear to differ, but aspects of the physical environment may be important. Objectively measured neighborhood environment factors warrant further investigation.

Park-and-ride (PnR) facilities provided by Australian transport authorities have been an effective way to encourage car drivers to use public transport such as trains and buses. However, as populations grow and vehicle running costs increase, the demand for more parking spaces has escalated. Often, PnR facilities are filled to capacity by early morning and commuters resort to parking illegally in streets surrounding stations. This paper reports on the development of a location-based parking finding service for PnR users. Based on their current location, the system can inform users which is the best station to park their cars during peak period. Two criteria—parking availability and the shortest travel time—were used to evaluate the best station. Fuzzy logic forecast models were used to estimate the uncertainty of parking availability during the peak parking demand period. A prototype using these methods has been developed based on a case study of the Oats Street and Carlisle PnR facilities in Perth, Western Australia. The system has proved to be efficacious and has the potential to be applied to other parking systems.

IntroductionMajor trauma patients are often perceived as being young males injured by high energy transfer mechanisms. The aim of this study was to describe the demographics of major trauma patients who were transported to hospital by ambulance.MethodsThis is a retrospective cohort study of adult major trauma (injury severity score >15) patients transported to hospital by St John Western Australia emergency ambulance in metropolitan Perth, between 1 January 2013 and 31 December 2016. To describe the cohort, median and interquartile range (IQR) were used for continuous variables and counts and percentages for categorical variables. Differences between mechanism of injury groups were assessed using the Kruskal-Wallis test. Trauma deaths were defined as early (declared deceased within 24 hours) or late (declared deceased within 30 days). ResultsA total of 1625 patients were included. The median age was 51 years (IQR 30-75) and 1158 (71%) were male. Falls from standing were the most common mechanism of injury (n=460, 28%) followed by motor vehicle crashes (n=259, 16%). Falls from standing were responsible for the majority of early (n=45/175, 26%) and late deaths (n=69/158, 44%). A large number of early deaths also resulted from motorbike crashes (n=32/175, 18%) with a median age of 34 years (IQR 21-46, p<0.001). ConclusionMajor trauma is not only a disease of the young. More than half of the cohort was more than 51 years of age and the most common cause was a fall from standing. Pre-hospital care must evolve to address the needs of a changing trauma patient demographic.

Introduction Almost all industries in Australia today have adopted digital media in some way. However, uses in large scale activities such as mining may seem to be different from others. This article looks at mining practices with a media studies approach, and concludes that, just as many other industries, mining and media have converged. Many Australian mine sites are adopting new media for communication and control to manage communication, explore for ore bodies, simulate forces, automate drilling, keep records, and make transport and command robotic. Beyond sharing similar digital devices for communication and computation, new media in mining employ characteristic digital media operations, such as numerical operation, automation and managed variability. This article examines the implications of finding that some of the most material practices have become mediated by new media. Mining has become increasingly mediated through new media technologies similar to GPS, visualisation, game remote operation, similar to those adopted in consumer home and mobile digital media. The growing and diversified adoption of digital media championed by companies like Rio Tinto aims not only ‘improve’ mining, but to change it. Through remediating practices of digital mining, new media have become integral powerful tools in prospective, real time and analytical environments. This paper draws on two well-known case studies of mines in the Pilbara and Western NSW. These have been documented in press releases and media reports as representing changes in media and mining. First, the West Angelas mines in the Pilbara is an open cut iron ore mine introducing automation and remote operation. This mine is located in the remote Pilbara, and is notable for being operated remotely from a control centre 2000km away, near Perth Airport, WA. A growing fleet of Komatsu 930E haul trucks, which can drive autonomously, traverses the site. Fitted with radars, lasers and GPS, these enormous vehicles navigate through the open pit mine with no direct human control. Introducing these innovations to mine sites become more viable after iron ore mining became increasingly profitable in the mid-2000s. A boom in steel building in China drove unprecedented demand. This growing income coincided with a change in public rhetoric from companies like Rio Tinto. They pointed towards substantial investments in research, infrastructure, and accelerated introduction of new media technologies into mining practices. Rio Tinto trademarked the term ‘Mine of the future’ (US Federal News Service 1), and publicised their ambitious project for renewal of mining practice, including digital media. More recently, prices have been more volatile. The second case study site is a copper and gold underground mine at Northparkes in Western NSW. Northparkes uses substantial sensing and control, as well as hybrid autonomous and remote operated vehicles. The use of digital media begins with prospecting, and through to logistics of transportation. Engineers place explosives in optimal positions using computer modelling of the underground rock formations. They make heavy use of software to coordinate layer-by-layer use of explosives in this advanced ‘box cut’ mine. After explosives disrupt the rock layer a kilometre underground, another specialised vehicle collects and carries the ore to the surface. The Sandvik loader-hauler-dumper (LHD) can be driven conventionally by a driver, but it can also travel autonomously in and out of the mine without a direct operator. Once it reaches a collection point, where the broken up ore has accumulated, a user of the surface can change the media mode to telepresence. The human operator then takes control using something like a games controller and multiple screens. The remote operator controls the LHD to fill the scoop with ore. The fully-loaded LHD backs up, and returns autonomously using laser senses to follow a trail to the next drop off point. The LHD has become a powerful mediator, reconfiguring technical, material and social practices throughout the mine. The Meanings of Mining and Media Are Converging Until recently, mining and media typically operated ontologically separately. The media, such as newspapers and television, often tell stories about mining, following regular narrative scripts. There are controversies and conflicts, narratives of ecological crises, and the economics of national benefit. There are heroic and tragic stories such as the Beaconsfield mine collapse (Clark). There are new industry policies (Middelbeek), which are politically fraught because of the lobbying power of miners. Almost completely separately, workers in mines were consumers of media, from news to entertainment. These media practices, while important in their own right, tell nothing of the approaching changes in many other sectors of work and everyday life. It is somewhat unusual for a media studies scholar to study mine sites. Mine sites are most commonly studied by Engineering (Bellamy & Pravica), Business and labour and cultural histories (McDonald, Mayes & Pini). Until recently, media scholarship on mining has related to media institutions, such as newspapers, broadcasters and websites, and their audiences. As digital media have proliferated, the phenomena that can be considered as media phenomena has changed. This article, pointing to the growing roles of media technologies, observes the growing importance that media, in these terms, have in the rapidly changing domain of mining. Another meaning for ‘media’ studies, from cybernetics, is that a medium is any technology that translates perception, makes interpretations, and performs expressions. This meaning is more abstract, operating with a broader definition of media — not only those institutionalised as newspapers or radio stations. It is well known that computer-based media have become ubiquitous in culture. This is true in particular within the mining company’s higher ranks. Rio Tinto’s ambitious 2010 ‘Mine of the Future’ (Fisher & Schnittger, 2) program was premised on an awareness that engineers, middle managers and senior staff were already highly computer literate. It is worth remembering that such competency was relatively uncommon until the late 1980s. The meanings of digital media have been shifting for many years, as computers become experienced more as everyday personal artefacts, and less as remote information systems. Their value has always been held with some ambivalence. Zuboff’s (387-414) picture of loss, intimidation and resistance to new information technologies in the 1980s seems to have dissipated by 2011. More than simply being accepted begrudgingly, the PC platform (and variants) has become a ubiquitous platform, a lingua franca for information workers. It became an intimate companion for many professions, and in many homes. It was an inexpensive, versatile and generalised convergent medium for communication and control. And yet, writers such as Gregg observe, the flexibility of networked digital work imposes upon many workers ‘unlimited work’. The office boundaries of the office wall break down, for better or worse. Emails, utility and other work-related behaviours increasingly encroach onto domestic and public space and time. Its very attractiveness to users has tied them to these artefacts. The trail that leads the media studies discipline down the digital mine shaft has been cleared by recent work in media archaeology (Parikka), platform studies (Middelbeek; Montfort & Bogost; Maher) and new media (Manovich). Each of these redefined Media Studies practices addresses the need to diversify the field’s attention and methods. It must look at more specific, less conventional and more complex media formations. Mobile media and games (both computer-based) have turned out to be quite different from traditional media (Hjorth; Goggin). Kirschenbaum’s literary study of hard drives and digital fiction moves from materiality to aesthetics. In my study of digital mining, I present a reconfigured media studies, after the authors, that reveals heterogeneous media configurations, deserving new attention to materiality. This article also draws from the actor network theory approach and terminology (Latour). The uses of media / control / communications in the mining industry are very complex, and remain under constant development. Media such as robotics, computer modelling, remote operation and so on are bound together into complex practices. Each mine site is different — geologically, politically, and economically. Mines are subject to local and remote disasters. Mine tunnels and global prices can collapse, rendering active sites uneconomical overnight. Many technologies are still under development — including Northparkes and West Angelas. Both these sites are notable for their significant use of autonomous vehicles and remote operated vehicles. There is no doubt that the digital technologies modulate all manner of the mining processes: from rocks and mechanical devices to human actors. Each of these actors present different forms of collusion and opposition. Within a mining operation, the budgets for computerised and even robotic systems are relatively modest for their expected return. Deep in a mine, we can still see media convergence at work. Convergence refers to processes whereby previously diverse practices in media have taken on similar devices and techniques. While high-end PCs in mining, running simulators; control data systems; visualisation; telepresence, and so on may be high performance, ruggedised devices, they still share a common platform to the desktop PC. Conceptual resources developed in Media Ecology, New Media Studies, and the Digital Humanities can now inform readings of mining practices, even if their applications differ dramatically in size, reliability and cost. It is not entirely surprising that some observations by new media theorists about entertainment and media applications can also relate to features of mining technologies. Manovich argues that numerical representation is a distinctive feature of new media. Numbers have always already been key to mining engineering. However, computers visualise numerical fields in simulations that extend out of the minds of the calculators, and into visual and even haptic spaces. Specialists in geology, explosives, mechanical apparatuses, and so on, can use plaftorms that are common to everyday media. As the significance of numbers is extended by computers in the field, more and more diverse sources of data provide apparently consistent and seamless images of multiple fields of knowledge. Another feature that Manovich identifies in new media is the capacity for automation of media operations. Automation of many processes in mechanical domains clearly occurred long before industrial technologies were ported into new media. The difference with new media in mine sites is that robotic systems must vary their performance according to feedback from their extra-system environments. For our purposes, the haul trucks in WA are software-controlled devices that already qualify as robots. They sense, interpret and act in the world based on their surroundings. They evaluate multiple factors, including the sensors, GPS signals, operator instructions and so on. They can repeat the path, by sensing the differences, day after day, even if the weather changes, the track wears away or the instructions from base change. Automation compensates for differences within complex and changing environments. Automation of an open-pit mine haulage system… provides more consistent and efficient operation of mining equipment, it removes workers from potential danger, it reduces fuel consumption significantly reducing greenhouse gas (GHG) emissions, and it can help optimize vehicle repairs and equipment replacement because of more-predictable and better-controlled maintenance. (Parreire and Meech 1-13) Material components in physical mines tend to become modular and variable, as their physical shape lines up with the logic of another of Manovich’s new media themes, variability. Automatic systems also make obsolete human drivers, who previously handled those environmental variations, for better or for worse, through the dangerous, dull and dirty spaces of the mine. Drivers’ capacity to control repeat trips is no longer needed. The Komatsu driverless truck, introduced to the WA iron ore mines from 2008, proved itself to be almost as quick as human drivers at many tasks. But the driverless trucks have deeper advantages: they can run 23 hours each day with no shift breaks; they drive more cautiously and wear the equipment less than human drivers. There is no need to put up workers and their families up in town. The benefit most often mentioned is safety: even the worst accident won’t produce injuries to drivers. The other advantage less mentioned is that autonomous trucks don’t strike. Meanwhile, managers of human labour also need to adopt certain strategies of modulation to support the needs and expectations of their workers. Mobile phones, televisions and radio are popular modes of connecting workers to their loved ones, particularly in the remote and harsh West Angelas site. One solution — regular fly-in-fly out shifts — tends also to be alienating for workers and locals (Cheshire; Storey; Tonts). As with any operations, the cost of maintaining a safe and comfortable environment for workers requires trade-offs. Companies face risks from mobile phones, leaking computer networks, and espionage that expose the site to security risks. Because of such risks, miners tend be subject to disciplinary regimes. It is common to test alcohol and drug levels. There was some resistance from workers, who refused to change to saliva testing from urine testing (Latimer). Contesting these machines places the medium, in a different sense, at the centre of regulation of the workers’ bodies. In Northparkes, the solution of hybrid autonomous and remote operation is also a solution for modulating labour. It is safer and more comfortable, while also being more efficient, as one experienced driver can control three trucks at a time. This more complex mode of mediation is necessary because underground mines are more complex in geology, and working environments to suit full autonomy. These variations provide different relationships between operators and machines. The operator uses a games controller, and watches four video views from the cabin to make the vehicle fill the bucket with ore (Northparkes Mines, 9). Again, media have become a pivotal element in the mining assemblage. This combines the safety and comfort of autonomous operation (helping to retain staff) with the required use of human sensorimotor dexterity. Mine systems deserve attention from media studies because sites are combining large scale physical complexity with increasingly sophisticated computing. The conventional pictures of mining and media rarely address the specificity of subjective and artefactual encounters in and around mine sites. Any research on mining communication is typically within the instrumental frames of engineering (Duff et al.). Some of the developments in mechanical systems have contributed to efficiency and safety of many mines: larger trucks, more rock crushers, and so on. However, the single most powerful influence on mining has been adopting digital media to control, integrate and mining systems. Rio Tinto’s transformative agenda document is outlined in its high profile ‘Mine of the Future’ agenda (US Federal News Service). The media to which I refer are not only those in popular culture, but also those with digital control and communications systems used internally within mines and supply chains. The global mining industry began adopting digital communication automation (somewhat) systematically only in the 1980s. Mining companies hesitated to adopt digital media because the fundamentals of mining are so risky and bound to standard procedures. Large scale material operations, extracting and processing minerals from under the ground: hardly to be an appropriate space for delicate digital electronics. Mining is also exposed to volatile economic conditions, so investing in anything major can be unattractive. High technology perhaps contradicts an industry ethos of risk-taking and masculinity. Digital media became domesticated, and familiar to a new generation of formally educated engineers for whom databases and algorithms (Manovich) were second nature. Digital systems become simultaneously controllers of objects, and mediators of meanings and relationships. They control movements, and express communications. Computers slide from using meanings to invoking direct actions over objects in the world. Even on an everyday scale, computer operations often control physical processes. Anti-lock Braking Systems regulate a vehicle’s braking pressure to avoid the danger when wheels lock-up. Or another example, is the ATM, which involves both symbolic interactions, and also exchange of physical objects. These operations are examples of the ‘asignifying semiotic’ (Guattari), in which meanings and non-meanings interact. There is no operation essential distinction between media- and non-media digital operations. Which are symbolic, attached or non-consequential is not clear. This trend towards using computation for both meanings and actions has accelerated since 2000. Mines of the Future Beyond a relatively standard set of office and communications software, many fields, including mining, have adopted specialised packages for their domains. In 3D design, it is AutoCAD. In hard sciences, it is custom modelling. In audiovisual production, it may be Apple and Adobe products. Some platforms define their subjectivity, professional identity and practices around these platforms. This platform orientation is apparent in areas of mining, so that applications such as the Gemcom, Rockware, Geological Database and Resource Estimation Modelling from Micromine; geology/mine design software from Runge, Minemap; and mine production data management software from Corvus. However, software is only a small proportion of overall costs in the industry. Agents in mining demand solutions to peculiar problems and requirements. They are bound by their enormous scale; physical risks of environments, explosive and moving elements; need to negotiate constant change, as mining literally takes the ground from under itself; the need to incorporate geological patterns; and the importance of logistics. When digital media are the solution, there can be what is perceived as rapid gains, including greater capacities for surveillance and control. Digital media do not provide more force. Instead, they modulate the direction, speed and timing of activities. It is not a complete solution, because too many uncontrolled elements are at play. Instead, there are moment and situations when the degree of control refigures the work that can be done. Conclusions In this article I have proposed a new conception of media change, by reading digital innovations in mining practices themselves as media changes. This involved developing an initial reading of the operations of mining as digital media. With this approach, the array of media components extends far beyond the conventional ‘mass media’ of newspapers and television. It offers a more molecular media environment which is increasingly heterogeneous. It sometimes involves materiality on a huge scale, and is sometimes apparently virtual. The mining media event can be a semiotic, a signal, a material entity and so on. It can be a command to a human. It can be a measurement of location, a rock formation, a pressure or an explosion. The mining media event, as discussed above, is subject to Manovich’s principles of media, being numerical, variable and automated. In the mining media event, these principles move from the aesthetic to the instrumental and physical domains of the mine site. The role of new media operates at many levels — from the bottom of the mine site to the cruising altitude of the fly-in-fly out aeroplanes — has motivated significant changes in the Australian industry. When digital media and robotics come into play, they do not so much introduce change, but reintroduce similarity. This inversion of media is less about meaning, and more about local mastery. Media modulation extends the kinds of influence that can be exerted by the actors in control. In these situations, the degrees of control, and of resistance, are yet to be seen.

In the contemporary urban environment of mass transit, it falls to a small group of public officers to keep large number of travellers safe. The small size of their force and the often limited powers they exert mean that these public safety ‘transit officers’ must project more authority and control than they really have. It is this ambience of authority and control which, in most situations they encounter and seek to influence, is enough to keep the public safe. This paper examines the ambience of a group of transit officers working on the railway lines of an Australian capital city. We seek to show how transit officers are both influenced by, and seek to influence, the ambience of their workplace and the public spaces they inhabit whilst on duty, and here we take ambience to apply to the surrounding atmosphere, the aura, and the emotional environment of a place or situation: the setting, tone, or mood. For these transit officers to keep the public safe, they must themselves remain safe. A transit officer who is disabled in a confrontation with a violent offender is unable to provide protection to his or her passengers. Thus, in the culture of the transit officers, their own workplace safety takes on a higher significance. It affects not just themselves. The ambience exuded by transit officers, and how transit officers see their relationship with the travelling public, their management and other organisational work groups, is an important determinant of their work group’s safety culture. Researching the Working Lives of Transit Officers in Perth Our discussion draws on an ethnographic study of the working lives and communication cultures of transit officers (TOs) employed by the Public Transport Authority (PTA) of Western Australia (WA). Transit officers have argued that to understand fully the challenges of their work it is necessary to spend time with them as they undertake their daily duties: roster in, roster out. To this end, the research team and the employer organisation secured an ARC Linkage Grant in partnership with the PTA to fund doctoral candidate and ethnographer Christine Teague to research the workers’ point of view, and the workers’ experiences within the organisation. The two-hundred TOs are unique in the PTA. Neither of the other groups who ride with them on the trains, the drivers and revenue protection staff (whose sole job is to sell and check tickets), experiences the combination of intense contact with passengers, danger of physical injury or group morale. The TOs of the PTA in Perth operate from a central location at the main train station and the end stations on each line. Here there are change lockers where they can lock up their uniforms and equipment such as handcuffs and batons when not on duty, an equipment room where they sign out their radios, and ticket-checking machines. At the main train station there is also a gym, a canteen and holding cells for offenders they detain. From these end stations and central location, the TOs fan out across the network to all suburbs where they either operate from stations or onboard the trains. The TOs also do ‘delta van’ duty providing rapid, mobile back-up support for their colleagues on stations or trains, and providing transport for arrested persons to the holding cell or police lock up. TOs are on duty whenever the trains are running–but the evenings and nights are when they are mainly rostered on. This is when trouble mostly occurs. The TOs’ work ends only after the final train has completed its run and all offenders who may require detaining and charging have been transferred into police custody. While the public perceive that security is the TOs’ most frequent role, much of the work involves non-confrontational activity such as assisting passengers, checking tickets and providing a reassuring presence. One way to deal with an ambiguous role is to claim an ambience of power and authority regardless. Various aspects of the TO role permit and hinder this, and the paper goes on to consider aspects of ambience in terms of fear and force, order and safety, and role confusion. An Ambience of Fear and Force The TOs are responsible for front-line security in WA’s urban railway network. Their role is to offer a feeling of security for passengers using the rail network after the bustle of the work day finishes, and is replaced by the mainly recreational travels of the after hours public. This is the time when some passengers find the prospect of evening travel on the public transport rail network unsettling–so unsettling that it was a 2001 WA government election promise (WA Legislative Council) that every train leaving the city centre after 7pm would have two TOs riding on it. Interestingly, recruitment levels have never been high enough for this promise to be fully kept. The working conditions of the TOs reflect the perception, and to an extent, the reality that some late night travel on public transport involves negotiating an edgy ambience with an element of risk, rubbing shoulders with people who may be loud, rowdy, travelling in a group, and or drug and alcohol affected. As Fred (all TO names are pseudonyms) comments: You’re not dealing with rational people, you’re not dealing with ‘people’: most of the people you’re dealing with are either drunk or under the influence of drugs, so they’re not rational, they don’t hear you, they don’t understand what you’re saying, they just have no sense of what’s right or wrong, you know? Especially being under the influence, so I mean, you can talk till you’re blue in the face with somebody who’s drunk or on drugs, I mean, all you have to say is one thing. ‘Oh, can I see your ticket please’, ‘oh, why do I need a fucking ticket’, you know? They just don’t get simple everyday messages. Dealing with violence and making arrest is a normal part of this job. Jo described an early experience in her working life as a TO:Within the first week of coming out of course I got smacked on the side of the head, but this lady had actually been certified, like, she was nuts. She was completely mental and we were just standing on the train talking and I’ve turned around to say something to my partner and she was fine, she was as calm as, and I turned around and talked to my partner and the next thing I know I ended up with her fist to the side of my head. And I went ‘what the hell was that’? And she went off, she went absolutely ballistic. I ended up arresting her because it was assault on an officer whether she was mental or not so I ended up arresting her.Although Jo here is describing how she experienced an unprovoked assault in the early days of her career as a TO, one of the most frequent precursors to a TO injury occurs when the TO is required to make an arrest. The injury may occur when the passenger to be arrested resists or flees, and the TO gives chase in dark or treacherous circumstances such as railway reserves and tunnels, or when other passengers, maybe friends or family of the original person of concern, involve themselves in an affray around the precipitating action of the arrest. In circumstances where capsicum spray is the primary way of enforcing compliance, with batons used as a defence tool, group members may feel that they can take on the two TOs with impunity, certainly in the first instance. Even though there are security cameras on trains and in stations, and these can be cued to cover the threatening or difficult situations confronting TOs, the conflict is located in the here-and-now of the exchanges between TOs and the travelling public. This means the longer term consequence of trouble in the future may hold less sway with unruly travellers than the temptation to try to escape from trouble in the present. In discussing the impact of remote communications, Rubert Murdoch commented that these technologies are “a powerful influence for civilised behaviour. If you are arranging a massacre, it will be useless to shoot the cameraman who has so inconveniently appeared on the scene. His picture will already be safe in the studio five thousand miles away and his final image may hang you” (Shawcross 242). Unfortunately, whether public aggression in these circumstances is useless or not, the daily experience of TOs is that the presence of closed circuit television (CCTV) does not prevent attacks upon them: nor is it a guarantee of ‘civilised behaviour’. This is possibly because many of the more argumentative and angry members of the public are dis-inhibited by alcohol or other drugs. Police officers can employ the threat or actual application of stun guns to control situations in which they are outnumbered, but in the case of TOs they can remain outnumbered and vulnerable until reinforcements arrive. Such reinforcements are available, but the situation has to be managed through the communication of authority until the point where the train arrives at a ‘manned’ station, or the staff on the delta vehicle are able to support their colleagues. An Ambience of Order and Safety Some public transport organisations take this responsibility to sustain an ambience of order more seriously than others. The TO ethnographer, Christine Teague, visited public transport organisations in the UK, USA and Canada which are recognised as setting world-class standards for injury rates of their staff. In the USA particularly, there is a commitment to what is called ‘the broken windows’ theory, where a train is withdrawn from service promptly if it is damaged or defaced (Kelling and Coles; Maple and Mitchell). According to Henry (117): The ‘Broken Windows’ theory suggests that there is both a high correlation and a causal link between community disorder and more serious crime: when community disorder is permitted to flourish or when disorderly conditions or problems are left untended, they actually cause more serious crime. ‘Broken windows’ are a metaphor for community disorder which, as Wilson and Kelling (1982) use the term, includes the violation of informal social norms for public behaviour as well as quality of life offenses such as littering, graffiti, playing loud radios, aggressive panhandling, and vandalism.This theory implies that the physical ambience of the train, and by extension the station, may be highly influential in terms of creating a safe working environment. In this case of ‘no broken window’ organisations, the TO role is to maintain a high ‘quality of life’ rather than being a role predominantly about restraining and bringing to justice those whose behaviour is offensive, dangerous or illegal. The TOs in Perth achieve this through personal means such as taking pride in their uniforms, presenting a good-natured demeanour to passengers and assisting in maintaining the high standard of train interiors. Such a priority, and its link to reduced workforce injury, suggests that a perception of order impacts upon safety. It has long been argued that the safety culture of an organisation affects the safety performance of that organisation (Pidgeon; Leplat); but it has been more recently established that different cultural groupings in an organisation conceive and construct their safety culture differently (Leith). The research on ‘safety culture’ raises a problematic which is rarely addressed in practice. That problematic is this: managers frequently engage with safety at the level of instituting systems, while workers engage with safety in terms of behaviour. When Glendon and Litherland comment that, contrary to expectations, they could find no relationship between safety culture and safety performance, they were drawing attention to the fact that much managerial safety culture is premised upon systems involving tick boxes and the filling in of report forms. The broken window approach combines the managerial tick box with managerial behaviour: a dis-ordered train is removed from service. To some extent a general lack of fit between safety culture and safety performance endorses Everett’s view that it is conceptually inadequate to conceive organisations as cultures: “the conceptual inadequacy stems from the failure to distinguish between culture and behavioural features of organizational life” (238). The general focus upon safety culture as a way of promoting improvements in safety performance assumes that compliance with a range of safety systems will guarantee a safe workplace. Such an assumption, however, risks positioning the injured worker as responsible for his or her own predicament and sets up an environment in which some management officials are wont to seek ways in which that injured worker’s behaviour failed to conform with safety rules or safety processes. Yet there are roles which place workers in harm’s way, including military duties, law enforcement and some emergency services. Here, the work becomes dangerous as it becomes disorderly. An Ambience of Roles and Confusion As the research reported here progressed, it became clear that the ambience around the presentation of the self in the role of a TO (Goffman) was an important part of how ‘safety’ was promoted and enacted in their work upon the PTA (WA) trains, face to face with the travelling public. Goffman’s view of all people, not specifically TOs, is that: Regardless of the particular objective which the individual has in mind and of his motive for having this objective, it will be in his interests to control the conduct of the others, especially their responsive treatment of him. This will largely be through influencing the perception and definition that others will come to formulate of him. He will influence them by expressing himself in such a way that the kind of impression given off will lead them to act voluntarily in accordance with his own plan. (3)This ‘influencing of perception’ is an important element of performing the role of a TO. This task of the TOs is made all the more difficult because of confusions about their role in relation to two other officers: police (who have more power to act in situations of public safety) and revenue project officers (who have less), as we now discuss. The aura of the TO role borrows somewhat from those quintessential law and order officers: the police. TOs work in pairs, like many police, to support each other. They have a range of legal powers including the power of arrest, and they carry handcuffs, a baton and capsicum spray as a means of helping ensure their safety and effectiveness in circumstances where they might be outnumbered. The tools of their trade are accessibly displayed on heavy leather belts around their waists and their uniforms have similarities with police uniforms. However, in some ways these similarities are problematic, because TOs are not afforded the same respect as police. This situation underlines of the ambiguities negotiated within the ambience of what it is to be a TO, and how it is to conduct oneself in that role. Notwithstanding the TOs’ law and order responsibilities, public perceptions of the role and some of the public’s responses to the officers can position these workers as “plastic cops” (Teague and Leith). The penultimate deterrent of police officers, the stun gun (Taser), is not available to TOs who are expected to control all incidents arising on duty through the fact that they operate in pairs, with capsicum spray available and, as a last resort, are authorised to use their batons in self defence. Furthermore, although TOs are the key security and enforcement staff in the PTA workforce, and are managed separately from related staff roles, they believe that the clarity of this distinction is compromised because of similarities in the look of Revenue Protection Officers (RPOs). RPOs work on the trains to check that passengers have tickets and have paid the correct fares, and obtain names and addresses to issue infringement notices when required. They are not PTA employees, but contracted staff from an outside company. They also work in pairs. Significantly, the RPO uniform is in many respects identical to that of the TO, and this appears to be a deliberate management choice to make the number of TOs seem greater than it is: extending the TO ambience through to the activities of the RPOs. However, in the event of a disturbance, TOs are required and trained to act, while RPOs are instructed not to get involved; even though the RPOs appear to the travelling public to be operating in the role of a law-and-order-keeper, RPOs are specifically instructed not to get involved in breaches of the peace or disruptive passenger behaviour. From the point of view of the travelling public, who observe the RPO waiting for TOs to arrive, it may seems as if a TO is passively standing by while a chaotic situation unravels. As Angus commented: I’ve spoken to quite a few members of public and received complaints from them about transit officers and talking more about the incident have found out that it was actually [RPOs] that are dealing with it. So it’s creating a bad image for us …. It’s Transits that are copping all the flak for it … It is dangerous for us and it’s a lot of bad publicity for us. It’s hard enough, the job that we do and the lack of respect that we do get from people, we don’t need other people adding to it and making it harder. Indeed, it is not only the travelling public who can mistake the two uniforms. Mike tells of an “incident where an officer [TO] has called for backup on a train and the guys have got off [the train at the next station] and just stood there, and he didn’t realise that they are actually [revenue protection] officers, so he effectively had no backup. He thought he did, but he didn’t.” The RPO uniform may confer an ambience of power borrowed from TOs and communicated visually, but the impact is to compromise the authority of the TO role. Unfortunately, what could be a complementary role to the TOs becomes one which, in the minds of the TO workforce, serves to undermine their presence. This effect of this role confusion is to dilute the aura of authority of the TOs. At one end of a power continuum the TO role is minimised by those who see it as a second-rate ‘Wannabe cop’ (Teague and Leith 2008), while its impact is diluted at the other end by an apparently deliberate confusion between the TO broader ‘law and order’ role, and the more limited RPO revenue collection activities. Postlude To the passengers of the PTA in Perth, the presence and actions of transit officers appear as unremarkable as the daily commute. In this ethnographic study of their workplace culture, however, the transit officers have revealed ways in which they influence the ambience of the workplace and the public spaces they inhabit whilst on duty, and how they are influenced by it. While this ambient inter-relationship is not documented in the organisation’s occupational safety and health management system, the TOs are aware that it is a factor in their level at safety at work, both positively and negatively. Clearly, an ethnography study is conducted at a certain point in time and place, and culture is a living and changing expression of human interaction. The Public Transport Authority of Western Australia is committed to continuous improvement in safety and to the investigation of all ways and means in which to support TOs in their daily activities. This is evident not only in their support of the research and their welcoming of the ethnographer into the workforce and onto the tracks, but also in their robust commitment to change as the findings of the research have progressed. In particular, changes in the ambient TO culture and in the training and daily practices of TOs have already resulted from this research or are under active consideration. Nonetheless, this project is a cogent indicator of the fact that a safety culture is critically dependent upon intangible but nonetheless important factors such as the ambience of the workplace and the way in which officers are able to communicate their authority to others.
