Purpose The purpose of this paper is twofold: first is to examine the changing spatio-temporal patterns and regional trends in residential fires; and second is to investigate the likely association of fire risk with seasons, calendar events and socio-economic disadvantage. Design/methodology/approach Using spatial analytic and predictive techniques, 11 years of fire incident data supplied by the Queensland Fire and Emergency Services are mapped and analysed. Findings The results show significant spatial and temporal variability in the distribution of residential fires. Residential fire incidents are more likely to occur in the inner city and across more disadvantaged areas. Mapped outputs show some areas in Brisbane at a higher risk of fire than others and that the risk of fire escalates at specific times of the year, in neighbourhoods with a higher disadvantage, during major sporting events and school holidays. The residential fires showed strong seasonal periodicity. There is a continuous yet gradual increase in the number of fire incidents recorded for all five sub-regions within SEQ. Sunshine Coast experienced the highest upward trend whereas Toowoomba and West Moreton show the lowest increase. Originality/value This study provides an empirical basis to guide future operational strategies through targeting high fire risk areas at particular times. This, in turn, will help utilise finite resources in areas where and when they need and thus enable minimise emergency management costs.

<p>Fluvial ecosystems have a huge potential to affect the global carbon budget. In particular, streams and rivers significantly contribute to carbon dioxide emissions. However, CO2 fluxes from streams to the atmosphere exhibit a marked spatial and temporal variability that is difficult to quantify. Spatio-temporal patterns of biogeochemical fluxes are the result of interconnected unsteady hydrological (e.g. discharge, stream’s length and area, air-water gas exchange velocities) and biochemical conditions. Local estimates of carbon dioxide fluxes from a water body require the simultaneous knowledge of gas exchange coefficients and carbon dioxide concentrations. Different methods (e.g. tracer gas addition, oxygen time series, eddy covariance technique, flux chambers) have been recently developed to obtain point or spatially integrated measures of carbon fluxes under different environmental conditions. Here, we present the results of a flume experiment conducted in the Lunzer Rinnen facility in Lunz am See (Austria). The contribution discusses the dependence of the air-water gas exchange velocities on a set of relevant physical flow properties (i.e. slope, water velocity, discharge). The experimental setup is representative of low slope/velocity streams (flume energy dissipation rate less than 0.01). Gas exchange velocities were evaluated interpreting CO2 observations derived from a standard and an ad-hoc designed flexible-foil CO2 chamber under different deployment modes - anchored and drifting. Our data confirms that higher slopes and flow velocity enhance air-water gas exchange velocities; hence, CO2 outgassing rates in rivers. Moreover, the flexible foil chamber developed for this experiment is shown to be a useful tool for the estimate of local CO2 outgassing rates as it reduces the turbulence induced by the standard chamber on the streamflow. Given the flexibility/simplicity of the floating chamber its use can improve the ability to quantify spatio-temporal patterns of CO2 outgassing in streams.</p>

This chapter addresses the benefits of geo-statistical approaches in fire prevention processes, and especially in the prevention of residential fires in urban areas. The aim is to demonstrate how residential fire incidents can be theorized and placed in a context where geo-statistical techniques and an area-based approach can support the emergency services fire prevention work. The chapter introduces theoretical concepts such as Fire Risk Environment, Fire Protection Capability, as well as de-termining factors, types of residential fires and various hypotheses for further analysis of residential fires in urban contexts. Key themes are the development of residential fire incidents in different metropolitan areas over time, how different types of residential fires can be connected to living conditions, and finally how the emergency services and other actors can work with area-based fire prevention. Examples from Sweden's major cities and especially the city of Gothenburg are used. The results show that variations in spatial residential fire patterns can be ex-plained by a variation of living conditions. The conditions may also look different depending on the residential area and housing conditions and therefore, preven-tive strategies and proactive measures should differ between and within cities and be adapted to specific different areas.

ABSTRACT Triliths are megalithic monuments scattered across the coastal plains of southern and southeastern Arabia. They consist of aligned standing stones with a parallel row of large hearths and form a space, the meaning of which is undoubtedly significant but nonetheless still unknown. This paper presents a new radiocarbon (14C) dataset acquired during the two field seasons 2018–2019 of the TSMO (Trilith Stone Monuments of Oman) project which investigated the spatial and temporal patterns of the triliths. The excavation and sampling of trilith hearths across Oman yielded a dataset of 30 new 14C dates, extending the use of trilith monuments to as early as the Iron Age III period (600–300 BC). The earlier dates are linked to two-phase trilith sites in south-central Oman. The three 14C pairs collected from the two-phase trilith sites indicated gaps between the trilith construction phases from 35 to 475 years (2 σ). The preliminary spatio-temporal analysis shows the geographical expansion of populations using trilith monuments during the 5th to 1st century BC and a later pull back in the 1st and 2nd century AD. The new 14C dataset for trilith sites will help towards a better understanding of Iron Age communities in southeastern Arabia.
