Natural disasters by definition are surprises, causing a great deal of damage and inconvenience. Earthquakes are among the most terrifying and destructive natural disasters threatening humans. Emergency management has been described as the process of coordinating an emergency or its aftermath through communication and organization for deployment and the use of emergency resources. This special section of HERA provides the state of the art studies of risk and emergency management related to the Wenchuan earthquake that occurred in China in May 2008.  相似文献

This special section considers contemporary efforts to account for climate change through four frames: measurement, management, morality and myth. Our introduction briefly outlines these perspectives and the relevant literature, asking: 1) How have techniques of measurement and quantification emerged from and contributed to the particular politics of the “Anthropocene”?; 2) How have our efforts to measure socioclimatic systems facilitated new techniques of socio-environmental management and, at times, worked to reshape the very systems they describe?; 3) How have accounting practices worked to both elucidate and obscure questions of morality, value, responsibility and justice?; and 4) How we might address the critique that climate science is a myth and improve understanding with greater incorporation of historical and cross cultural knowledge from human ecology, human geography and anthropology.  相似文献

Land-use and climate change are major threats to biodiversity and ecosystem functions. Most of the current biodiversity monitoring systems are based on periodic records of the populations of a set of threatened or popular ‘flagship’ indicator species. In contrast to the abundance-based monitoring of species, also specific indicators of processes and functional interactions in an ecosystem may become targets of a more functional monitoring which can unveil early responses of an ecosystem to environmental changes at different spatial and temporal scales. The contributions of this Special Issue present such functional indicators for assessing and predicting responses to environmental changes of ecosystem functions in a hotspot of tropical biodiversity.  相似文献

Applying latent class and regression techniques to data from the NICHD Study of Early Child Care and Youth Development (n = 997), this study explored the potential academic advantages of time spent in out-of-school activities. Of particular interest was how these potential advantages played out in relation to the timing and duration of activity participation and the family contexts in which it occurred. Participation closer to the start of high school—including consistent participants and latecomers—was associated with higher grades at the transition into high school, especially for youth from low-income families. Sensitivity analyses indicated that this link between school-age activity participation and adolescent academic progress was unlikely to be solely a function of selection. It also tended to be more pronounced among youth from lower-income families, although without varying by other aspects of family status or process.  相似文献

The papers in this special issue of Human Nature collectively consider societal and individual responses to a wide variety of environmental and social risks. The first paper considers societal level effects of pathogen risk on collectivism and conformity, avoidance of outsiders, and in-group loyalty in a worldwide cross-cultural sample. The second deals with societal-level effects of resource unpredictability on the nature and conduct of warfare in eastern Africa. The third deals with effects of volcanic eruptions and earthquakes and mediating factors on individual perceptions of risk in Mexico and Ecuador. The final paper deals with effects of various types of father absence on women’s reproductive life histories in Bangladesh.  相似文献

Risk-sensitive behavior is the phenomenon of animals exhibitingpreferences when offered choices whose outcomes differ in theirdegree of variance. It is now well demonstrated that many animalsare sensitive to differences in the magnitude of variance inrewards. A considerable body of literature on risk sensitivityhas been generated in recent years, encompassing theoreticaland empirical work, from both functional and mechanistic approaches.Nevertheless, it is less than clear how animal preferences forvariability are determined. It is therefore timely to look broadlyat what has been accomplished, and to identify the most promisingsynthetic approaches for future work.  相似文献

The synapse is formed between a presynapse (which releases neurotransmitter) and the postsynapse (which transduces this chemical signal). Over the past decade, presynaptic dysfunction has emerged as a key mediator of a series of neurodevelopmental and neurodegenerative disorders. This special issue will highlight some of the important presynaptic molecules and mechanisms that are disrupted in these conditions and reveal potential routes for therapy.  相似文献
