Abstract:
... Soundscapes are increasingly used as innovative entry doors in environmental studies. Facing huge libraries of sound files which cannot be processed manually, acoustic indices provide an overview to the information contained in them, as well as to allow for automatic processing. Studies dealing with such indices have, however, focused more on specific topics or indices than on the overall characte ...

Abstract:
... In this study, we present an alternate approach to archaeological typology, using deep learning to classify digital images of decorated pottery sherds into an existing typological framework. The study focuses on a specific kind of ancient painted pottery from the American Southwest, Tusayan White Ware, but we believe it has broader implications for a wide range of geographical settings and artifac ...

Abstract:
... Practitioners and researchers use vulnerability indices to understand the conditions that influence hazard risk. However, there has been little research on how well such indices depict household-scale vulnerability to specific hazards. We examined relationships between an all-hazard index and a hazard-specific index with household-level adaptive resources, adaptive behaviors, proximate sensitiviti ...

Abstract:
... Understanding how natural variation in flow regimes influences stream ecosystem structure and function is critical to the development of effective stream management policies. Spatial variation in flow regimes among streams is reasonably well understood for streams in mesic regions, but a more robust characterization of flow regimes in arid regions is needed, especially to support biological monito ...

Abstract:
... Local grain economies are being developed in North America and Europe as alternatives to the global grain economy and its negative externalities. Little is known, however, about their size, structure, and sustainability, in particular as they evolve. This study offers such insights from a case study of the local grain economy in Arizona. The study uses an analytical framework that combines quantit ...

Abstract:
... Many energy policies are implemented to subsidize the adoption of energy efficiency. However, when private benefits from energy efficiency exceed the social benefits, there is an incentive for the consumers to over-invest in energy efficiency; otherwise, there is an incentive to under-invest. This study adds to this discussion by providing an empirical estimation of the electricity savings and soc ...

Abstract:

This approach is based on a broad concept of environment as “set” having spatially dispersed and regionally defined attributes, as opposed to something that is mutable at the scale of individual groups of humans l ...
