Floods are a natural hazard evolving in space and time according to meteorological and river basin dynamics, so that a single flood event can affect different regions over the event duration. This physical mechanism introduces spatio‐temporal relationships between flood records and losses at different locations over a given time window that should be taken into account for an effective assessment of the collective flood risk. However, since extreme floods are rare events, the limited number of historical records usually prevents a reliable frequency analysis. To overcome this limit, we move from the analysis of extreme events to the modeling of continuous stream flow records preserving spatio‐temporal correlation structures of the entire process, and making a more efficient use of the information provided by continuous flow records. The approach is based on the dynamic copula framework, which allows for splitting the modeling of spatio‐temporal properties by coupling suitable time series models accounting for temporal dynamics, and multivariate distributions describing spatial dependence. The model is applied to 490 stream flow sequences recorded across 10 of the largest river basins in central and eastern Europe (Danube, Rhine, Elbe, Oder, Waser, Meuse, Rhone, Seine, Loire, and Garonne). Using available proxy data to quantify local flood exposure and vulnerability, we show that the temporal dependence exerts a key role in reproducing interannual persistence, and thus magnitude and frequency of annual proxy flood losses aggregated at a basin‐wide scale, while copulas allow the preservation of the spatial dependence of losses at weekly and annual time scales.  相似文献

The outbreak of a highly communicable disease, SARS, in Asia in 2003 has revealed the health risk of living in a high-density environment. To show the important connection between human health and environmental quality, this study surveys the prevalence of sick building syndrome (SBS) among apartment residents and their evaluation of indoor environmental quality (IEQ). Based on a sample of 748 households living in Hong Kong, two interesting findings are revealed: (1) nasal discomfort was the commonest home-related SBS symptom despite the absence of any central ventilation system in apartment buildings; (2) noise, rather than ventilation, was the major IEQ problem perceived by residents. Our statistical analysis further showed that residents with SBS symptoms were less satisfied with their IEQ than those without. That is, despite a positive evaluation of specific IEQ criteria with respect to the building residents lived in, if they reported feeling SBS related symptoms, the overall IEQ evaluation of their building could still be negative. This perception bias gives rise to a sample selection problem in measuring perceived IEQ, which has implications on housing management practices and the formulation of a healthy housing policy.  相似文献

The anthropology of development seeks to understand the complex encounter between international and national development regimes and local patterns of livelihood and being. As science and development move objects, at once material and discursive, through the networks of the social to reach “impoverished” others, local groups reach out to development actors to evaluate and appropriate their resources and accept or redirect those efforts. In a political interplay of disciplinary measures and localizing translations, development projects are re-invented, or aspects thereof refused, just as development actors strain to keep projects on track. With input from science and technology studies, this article explores the participatory, authoritative, and distributive dimensions to agricultural development in East Timor. Across four cases studies—a dairy, a greenhouse, a seed development program, and a permanent farming initiative—the politics of projects are compared and discussed within the broader context of colonial and postcolonial development. The article is based on a total of 1 year of fieldwork conducted in 2003, 2008, and 2009.  相似文献

Infants follow the gaze of an individual with whom they are directly interacting by the end of the first year. By 18 months infants are capable of learning novel words in observational (or third‐party) contexts (Floor & Akhtar, 2006). To examine third‐party gaze following in 12‐ and 18‐month‐olds, the parent and experimenter engaged in a conversation while the infant was present. For 8 trials approximately every 30 sec the experimenter would turn her head to the right or left to fixate on a toy placed on either side of the room with the parent following suit. In the first experiment, the parent was seated next to the infant and the experimenter opposite, whereas in the second experiment the positions of the adults were switched. In Experiment 1, 18‐month‐olds but not 12‐month‐olds followed gaze. In Experiment 2, 12‐month‐olds acquired a tendency to follow gaze during the experimental session. These results suggest that an incipient ability to follow third‐party gaze is present by 12 months and that infants acquire a more reliable and general ability to follow the gaze of noninteractive others between 12 and 18 months.  相似文献

This paper revisits Parsons's conception of the 'sick role' and examines the relevance of his writings on the cultural understanding of sickness to the consumption of health in the contemporary era. In terms of current developments, I focus on the development of pro-active approaches towards the healthy body, and the growth of 'information rich' consumers of health care. These have become prominent themes in sociology, and while Parsons's writings are usually viewed as anachronistic I argue they remain highly pertinent to understanding the emergence of informed, body conscious lay people. If Parsons's analysis of health is more relevant to current circumstances than many critics assume, however, it is not unproblematic. The residual categories associated with the sick role obscure the continued utility of his work on the general cultural values informing health care. It is Parsons's analysis of these values, I suggest, that needs rescuing from restricted understandings of the sick role and highlighting as an important resource for contemporary theorists.  相似文献

The global telecommunications changed from a number of co-operating national monopolies offering a restricted range of services to a competitive, growing market with players of many types and sizes, offering a large range of services. How can vertically integrated incumbents align themselves and their systems to best compete in this environment? Business patterns and enterprise modelling offer a tool to model a large organization as a number of smaller enterprises that can compete with and co-operate with smaller specialist players in the market. In order to identify enterprises, this paper proposes that there are only a limited number of types of enterprise (manufacturer, service supplier, reseller, that these enterprise types can only interact in a limited number of ways (component supply, aggregation supply, resell supply, trading, end-supply and commission). With the use of examples, this paper illustrates these types of enterprise and enterprise relationships, and how they can be combined to build both internal and external supply chains, and discusses some of the conclusions that can be drawn from this analysis.  相似文献
