Most Coverage Path Planning (CPP) strategies based on the minimum width of a concave polygonal area are very likely to generate non-optimal paths with many turns. This paper introduces a CPP method based on a Region Optimal Decomposition (ROD) that overcomes this limitation when applied to the path planning of an Unmanned Aerial Vehicle (UAV) in a port environment. The principle of the approach is to first apply a ROD to a Google Earth image of a port and combining the resulting sub-regions by an improved Depth-First-Search (DFS) algorithm. Finally, a genetic algorithm determines the traversal order of all sub-regions. The simulation experiments show that the combination of ROD and improved DFS algorithm can reduce the number of turns by 4.34%, increase the coverage rate by more than 10%, and shorten the non-working distance by about 29.91%. Overall, the whole approach provides a sound solution for the CPP and operations of UAVs in port environments.

Interest in news literacy inside and outside the academy has grown alongside related concerns about the quality of news and information available. Attempts to fully define, explicate and operationalize news literacy, however, are scattered. Drawing on literature across journalism and mass communication, we propose a definition of news literacy that combines knowledge of news production, distribution and consumption with skills that help audiences assert control over their relationship with news. We propose that knowledge and skills should be conceptualized across five domains: context, creation, content, circulation and consumption. This explication offers a clear, concise and cohesive path for research about news literacy, especially empirical testing to evaluate news literacy and its effectiveness in contributing to relevant behaviours. This framework also offers a consistent, yet flexible, approach to measuring news literacy across diverse contexts.
