    The dependence of precipitation and its footprint on atmospheric temperature in idealized extratropical cyclones

    Flood hazard is a function of the magnitude and spatial pattern of precipitation accumulation. The sensitivity of precipitation to atmospheric temperature is investigated for idealized extratropical cyclones, enabling us to examine the footprint of extreme precipitation (surface area where accumulated precipitation exceeds high thresholds) and the accumulation in different-sized catchment areas. The mean precipitation increases with temperature, with the mean increase at 5.40%/∘C. The 99.9th percentile of accumulated precipitation increases at 12.7%/∘C for 1 h and 9.38%/∘C for 24 h, both greater than Clausius-Clapeyron scaling. The footprint of extreme precipitation grows considerably with temperature, with the relative increase generally greater for longer durations. The sensitivity of the footprint of extreme precipitation is generally super Clausius-Clapeyron. The surface area of all precipitation shrinks with increasing temperature. Greater relative changes in the number of catchment areas exceeding extreme total precipitation are found when the domain is divided into larger rather than smaller catchment areas. This indicates that fluvial flooding may increase faster than pluvial flooding from extratropical cyclones in a warming world. When the catchment areas are ranked in order of total precipitation, the 99.9th percentile is found to increase slightly above Clausius-Clapeyron expectations for all of the catchment sizes, from 9 km2 to 22,500 km2. This is surprising for larger catchment areas given the change in mean precipitation. We propose that this is due to spatially concentrated changes in extreme precipitation in the occluded fron

    Constructing and maintaining houses

    This resource sheet is about the construction and maintenance of Indigenous housing. It does not cover broader questions such as the total amount of housing required or the best housing management systems, although it touches on these issues. It describes the best approaches to the constructionwas slightly better in Non-remote areas, the issue is not just one of remoteness—even in Non-remote areas the percentage of houses requiring major repair or replacement was 28% (see Figure 1)

    Is There Monopsony in the Labor Market? Evidence from a Natural Experiment

    Get PDF
    A variety of recent theoretical and empirical advances have renewed interest in monopsonistic models of the labor market. However, there is little direct empirical support for these models, even in labor markets that are textbook examples of monopsony. We use an exogenous change in wages at Veterans Affairs hospitals as a natural experiment to investigate the extent of monopsony in the nurse labor market. In contrast to much of the prior literature, we estimate that labor supply to individual hospitals is quite inelastic, with short-run elasticity around 0.1. We also find that non-VA hospitals responded to the VA wage change by changing their own wages.

    Are you concerned about such issues as reproductive freedom, the ERA, equal pay for equal work, rape, sexual harassment, and the recent conservative swing in American political thought? The UMO Women\u27s center is a campus group that shares these concerns and provides a forum for action and discussion. We urge campus and community women and men to join us in our examination of these changing aspects of society

    Planning for sustainable change: a review of Australian local planning schemes

    Get PDF
    Sustainable development, defined by the World Commission on Environment and Development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs’, has become a global policy objective with particular resonance for planners (WCED, 1987: p. 43). Many international, national, state and regional policy frameworks emphasise the need to improve the environmental performance of cities and regions and to conserve and renew biodiversity. The increasing prospect of global climatic volatility – hotter temperatures, sea level rise, intense storm events, flooding and bushfires, have added a new urgency for planning and design regulations that build community resilience to withstand impacts of climate change (Hennessy et al., 2007)
