Impact of speed change on estimated journey time: Failure of drivers to appreciate relevance of initial speed

Higher speeds are associated with increases in the probability of crashing and the severity of the outcome. Logically drivers speed to save time, and research evidence supports this assertion. It is therefore important to investigate drivers’ understanding of how speed change impacts on journey time. Since it is likely that drivers do not appreciate the reciprocal nature of the function which links these two variables, and its implications, two predictions can be made: the impact of a speed change will be underestimated at low speeds and overestimated at high speeds. This issue was addressed through four questions generated by manipulating Speed Change (increase versus decrease) and Starting Speed (30 mph versus 60 mph) with the participants being asked how they felt these variables would impact on journey time. These were included in a large survey addressing speed-related issues. Participants were a representative quota sample of 1005 UK drivers, interviewed by questionnaire. The findings indicated that three of the four questions produced results consistent with the predictions made. Furthermore, a repeated measures factorial ANOVA indicated that there was no real appreciation of how starting speed impacted on journey time. A disordinal interaction provided evidence that drivers wrongly believed that as starting speed increased the impact of a speed rise also increased; the opposite is true. For speed decreases, drivers appeared to think that starting speed had little impact on the amount of time saved. It is recommended that these findings be integrated into driver training and speed awareness courses.     

The Privatisation of Public Property: the Development of a Shopping Mall in Sydney and its Implications for Governance through Spatial Practices

This article examines the planning application and current operation of a new shopping mall in Sydney. I use this analysis to argue that the owners of the mall, Westfield, govern, through spatial practices, the physical space in the mall and the shopping practices of the people who enter the mall. By the term govern I mean the spatial practices by which Westfield controls the shopping area of the mall. I follow the idea of governance inspired by the governmentality literature to show that those connected with the mall are shaped by spatial practices which envisages subjects which are morally free and yet are shaped by shopping mall practices (Foucault, 1975, 1980).

By these spatial practices, I argue, Westfield creates a certain ambience in the mall, which conveys the message that the mall is an attractive and safe location, which welcomes certain customers and excludes others. This collective impression of mall atmosphere, I argue acts as a spatial practice, which in effect governs the mall.

One of the features of shopping malls is that public or civic space is replaced with 'semi-public space' owned by developers. In this context the protection of private property has coalesced with the preservation of public order (Gray and Gray, 2000, p. 23). In shopping malls people considered disruptive to shopping are excluded and shops found in the high street such as pawnshops and second-hand bookshops are not granted a tenancy. Other unwelcome folk include the homeless and groups of teenagers.

n this article I plan to analyse the spatial practices which restrict full public access to such places as the Hornsby shopping mall. Accordingly, I firstly show that the concept of property should rightly be seen as containing social ideas, secondly I discuss the nature of spatial practices, which materially and discursively lead to the exclusion of certain people and thirdly, describe notions of community which help define who are proper mall entrants.     

The Shopping Jacket: Wearable computing for the consumer

As part of the Bristol Wearable Computing Initiative, we are exploring location-sensing systems suitable for use with wearable computing. In this paper we present our findings, and in particular a wearable application — the ‘Shopping Jacket’ — which relies on a minimal infrastructure to be effective. We use two positioning devices, ‘pingers’ and GPS. The pinger is used to signal the presence of a shop, and to indicate the type of shop and its website. The GPS is used to disambiguate which branch of a high street chain is being passed. The wearable uses this information to determine whether the wearer needs to be alerted that they are passing an interesting shop, or to direct the wearer around a shopping mall. The Shopping Jacket integrates a wearable CardPC, GPS and pinger receivers, a near-field radio link, hand-held display, GSM data telephone and a speech interface into a conventional sports blazer.     

Assessment of Fire Hazard in Small News Agents in Transport Terminal Halls

A large amount of combustibles are stored in small newspapers and magazine shops in terminal halls known as news agents in the Far East. Fire safety for those small shops located in crowded public transport interchanges should be evaluated carefully. In carrying out fire hazard assessment, the possible heat release rates should be estimated so that consequences of a fire can be assessed. As the shops are small with easily ignited combustibles, transition to a postflashover fire would be rapid. Therefore, the resultant heat release rates should be measured by burning those combustibles under flashover conditions. Hazard assessments based on full-scale burning tests for postflashover news agent fires performed in remote areas in China are reported in this paper. The effect of reducing the heat release rate by discharging water mists is illustrated. Such fire suppression systems are recommended for use in such shops.
