No full textData are stored in separate .csv/Excel files. All information identifying the coders of this data has been removed.A changing Antarctica carries large implications for global climate systems and sea level rise. However, how climate change is altering Antarctica and how these changes and their relevance are communicated in news media remains unclear. This study explores how Antarctica, climate change, and sea level rise are reported in news media by conducting a content analysis of Antarctic climate coverage in seven U.S. newspapers between March 2007 and December 2022. Findings suggest that newspaper reporting of Antarctica’s changing climate is limited, and that framed coverage about Antarctica, climate change, and sea level rise primarily emphasizes scientific and ecological implications.

Improving navigation and preventing erosion near San Pablo, Bolivar
No full textIn this report a study is carried out on the Magdalena River near the village of San Pablo, Colombia. The Magdalena River near San Pablo experiences two major issues which are related to navigation and erosion. The major problem for inland navigation is the sharp bend of the Magdalena River at San Pablo, which has too small a radius, causing problems for navigation. Furthermore, there are some parts in the considered river reach where the water depth is insufficient according to the requirements for navigability. Regarding the erosion problem near San Pablo, the main driving force is assumed to be high flow velocities and large near-bank water depths due to spiral flow in the outer bend. The main flow passing by the river bank of San Pablo gradually takes soil particles away, resulting in a continuous erosion process. In addition, the developed steep slope and height of the river bank results in mass failure mechanisms, increasing the erosion problems even further in the future. Several possiblemeasures have been analysed to solve this navigational problem, such as river training works consisting of groynes, longitudinal dams and a spit, where the latter one consists of a land tongue and a longitudinal dam connected to it. Measures with an even bigger impact are also considered, such as a bend cut-off and a river bypass. There are several possible measures to solve the erosion problem, such as a revetment, groynes and geogrids. Both the navigability and erosion problem can be solved in an integral way by a combination of different measures. In this study five alternatives are proposed, which are groynes, a spit, longitudinal dams, a bend cut-off and a river bypass. With the help of a multi-criteria analysis the most promising alternatives have been selected, which showed the spit to be the best in terms of reducing erosion and increasing navigation possibilities. With the help of the Delft3D model the general up- and downstream consequences have been explored of the most promising alternatives. The large river training structures, such as longitudinal dams and a bend cut-off, do not result in the desired behaviour of the river reach. Therefore, it is not advised to completely restrict the river in its flow conditions since this in general leads to more difficulties as the restriction does not allow the river to get to its equilibrium within a short period of time. However, both the groynes and the spit pose fewer restrictions to the river flow and show large improvements of the current situation in terms of navigability and erosion. The groynes are especially successful in reducing erosion problems at the river bank of San Pablo. However, the spit is more effective in driving the main part of the flow through the current navigation channel, which results in a deeper and wider channel. Therefore, it is recommended to combine the spit and the groynes to obtain an integrated solution for both erosion and navigation problems. However, for both river training works, erosion problems are encountered downstream of San Pablo. This should be a major part of future research since problems should be solved instead of shifted up- or downstream.Water Management, Hydraulic EngineeringCivil Engineering and Geoscience

A research agenda for the science of actionable knowledge: Drawing from a review of the most misguided to the most enlightened claims in the science-policy interface literature
No full textLinking science with action affords a prime opportunity to leverage greater societal impact from research and increase the use of evidence in decision-making. Success in these areas depends critically upon processes of producing and mobilizing knowledge, as well as supporting and making decisions. For decades, scholars have idealized and described these social processes in different ways, resulting in numerous assumptions that now variously guide engagements at the interface of science and society. We systematically catalog these assumptions based on prior research on the science-policy interface, and further distill them into a set of 26 claims. We then elicit expert perspectives (n = 16) about these claims to assess the extent to which they are accurate or merit further examination. Out of this process, we construct a research agenda to motivate future scientific research on actionable knowledge, prioritizing areas that experts identified as critical gaps in understanding of the science-society interface. The resulting agenda focuses on how to define success, support intermediaries, build trust, and evaluate the importance of consensus and its alternatives – all in the diverse contexts of science-society-decision-making interactions. We further raise questions about the centrality of knowledge in these interactions, discussing how a governance lens might be generative of efforts to support more equitable processes and outcomes. We offer these suggestions with hopes of furthering the science of actionable knowledge as a transdisciplinary area of inquiry. © 2023 The AuthorsOpen access articleThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Food for contagion: synthesis and future directions for studying host-parasite responses to resource shifts in anthropogenic environments
No full textHuman-provided resource subsidies for wildlife are diverse, common and have profound consequences for wildlife-pathogen interactions, as demonstrated by papers in this themed issue spanning empirical, theoretical and management perspectives from a range of study systems. Contributions cut across scales of organization, from the within-host dynamics of immune function, to population-level impacts on parasite transmission, to landscape- and regional-scale patterns of infection. In this concluding paper, we identify common threads and key findings from author contributions, including the consequences of resource subsidies for (i) host immunity; (ii) animal aggregation and contact rates; (iii) host movement and landscape-level infection patterns; and (iv) interspecific contacts and cross-species transmission. Exciting avenues for future work include studies that integrate mechanistic modelling and empirical approaches to better explore cross-scale processes, and experimental manipulations of food resources to quantify host and pathogen responses. Work is also needed to examine evolutionary responses to provisioning, and ask how diet-altered changes to the host microbiome influence infection processes. Given the massive public health and conservation implications of anthropogenic resource shifts, we end by underscoring the need for practical recommendations to manage supplemental feeding practices, limit human-wildlife conflicts over shared food resources and reduce cross-species transmission risks, including to humans.This article is part of the theme issue 'Anthropogenic resource subsidies and host-parasite dynamics in wildlife'
