Water resources are greatly impacted by natural disasters, but very little is known about how these issues are portrayed in the media across different types of disasters. Using a corpus of over 600 thousand local newspaper articles, this research evaluates whether the amount of coverage of water-related concerns of fires and hurricanes reflects news values associated with magnitude and proximity. A more detailed analysis focused on wildfires, which occur on undeveloped land and have the potential to spread rapidly, was also conducted to further evaluate spatial patterns in disaster-related water coverage. Our results indicate that the newspaper coverage patterns for water issues are not equally connected to magnitude and proximity values for fires and hurricanes. In our sample, coverage of water issues in relation to fires and wildfires consistently had an inverse relationship with overall event magnitudes, whereas the coverage of water issues in relation to hurricanes demonstrated a positive correlation. Although wildfires are more likely to be clustered in the western part of the country, there was a lack of positive correlations with wildfire magnitudes in this region. Possible influences for these patterns (e.g., limited impacts to humans and lack of shock-value) are discussed. Given the media’s role in facilitating disaster management and recovery, these nuances in coverage variations provide insight into opportunities for informing water security, which is especially important given the increasing frequency of natural disasters.
Social media has enabled users and organizations to obtain information about technology usage like software usage and even security feature usage. However, on the dark side it has also allowed an adversary to potentially exploit the users in a manner to either obtain information from them or influence them towards decisions that might have malicious settings or intents. While there have been substantial efforts into understanding how social influence affects one's likelihood to adopt a security technology, especially its correlation with the number of friends adopting the same technology, in this study we investigate whether peer influence can dictate what users decide over and above their own knowledge. To this end, we manipulate social signal exposure in an online controlled experiment with human participants to investigate whether social influence can be harnessed in a negative way to steer users towards harmful security choices. We analyze this through a controlled game where each participant selects one option when presented with six security technologies with differing utilities, with one choice having the most utility. Over multiple rounds of the game, we observe that social influence as a tool can be quite powerful in manipulating a user's decision towards adoption of security technologies that are less efficient. However, what stands out more in the process is that the manner in which a user receives social signals from its peers decides the extent to which social influence can be successful in changing a user's behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
