TL;DR: In this article, the authors identify a conceptual framework within which the effects of these re-imaging initiatives on tourists' images can be understood and demonstrate that the pursuit of image change through these processes has important implications for the general direction and outcomes of wider regeneration objectives.
Abstract: In recent years many post-industrial cities have implemented ambitious re-imaging strategies to appeal to a variety of external audiences. This paper identifies a conceptual framework within which the effects of these initiatives on tourists' images can be understood. The framework contends that re-imaging can affect different city image components through the connotations and synecdochical images generated. The value of this framework is then illustrated by its application to the re-imaging initiatives adopted by Barcelona, Catalonia, Spain. This case study reveals that the mechanisms identified in the framework are useful ways of explaining how city images are modified. It also suggests that the pursuit of image change through these processes has important implications for the general direction and outcomes of wider regeneration objectives.

TL;DR: In this paper, the authors propose a functional-flow approach to manage heavily modified rivers, which focuses on retaining specific process-based components of the hydrograph, or functional flows, rather than attempting to mimic the full natural flow regime.
Abstract: Building on previous environmental flow discussions and a growing recognition that hydrogeomorphic processes are inherent in the ecological functionality and biodiversity of riverscapes, we propose a functional-flows approach to managing heavily modified rivers. The approach focuses on retaining specific process-based components of the hydrograph, or functional flows, rather than attempting to mimic the full natural flow regime. Key functional components include wet-season initiation flows, peak magnitude flows, recession flows, dry-season low flows, and interannual variability. We illustrate the importance of each key functional flow using examples from western US rivers with seasonably predictable flow regimes. To maximize the functionality of these flows, connectivity to morphologically diverse overbank areas must be enhanced in both space and time, and consideration must be given to the sediment-transport regime. Finally, we provide guiding principles for developing functional flows or incorporating functional flows into existing environmental flow frameworks.

TL;DR: The authors explored tourism policy making from the perspectives of policy makers using grounded theory and found that policy making is essentially a social process, involving communication and negotiation between people in the context of wider change, and further research to investigate the communications involved in producing policy rather than the current research focus on the tangible outputs of the process such as a plan or a physical development.

TL;DR: P(3HB) scaffolds with multifunctionalities (viz. bactericidal, bioactive, electrically conductive, antioxidative behaviour) were produced, which paves the way for next generation of advanced scaffolds for bone tissue engineering.

TL;DR: It is shown that even the hyperarid Atacama Desert can provide a habitable environment for microorganisms that allows them to become metabolically active following an episodic increase in moisture and that once it decreases, so does the activity of the microbiota.
Abstract: Traces of life are nearly ubiquitous on Earth. However, a central unresolved question is whether these traces always indicate an active microbial community or whether, in extreme environments, such as hyperarid deserts, they instead reflect just dormant or dead cells. Although microbial biomass and diversity decrease with increasing aridity in the Atacama Desert, we provide multiple lines of evidence for the presence of an at times metabolically active, microbial community in one of the driest places on Earth. We base this observation on four major lines of evidence: (i) a physico-chemical characterization of the soil habitability after an exceptional rain event, (ii) identified biomolecules indicative of potentially active cells [e.g., presence of ATP, phospholipid fatty acids (PLFAs), metabolites, and enzymatic activity], (iii) measurements of in situ replication rates of genomes of uncultivated bacteria reconstructed from selected samples, and (iv) microbial community patterns specific to soil parameters and depths. We infer that the microbial populations have undergone selection and adaptation in response to their specific soil microenvironment and in particular to the degree of aridity. Collectively, our results highlight that even the hyperarid Atacama Desert can provide a habitable environment for microorganisms that allows them to become metabolically active following an episodic increase in moisture and that once it decreases, so does the activity of the microbiota. These results have implications for the prospect of life on other planets such as Mars, which has transitioned from an earlier wetter environment to today's extreme hyperaridity.
