The media’s coverage of mass public shootings in America: fifty years of newsworthiness

This study uses a media distortion analysis to examine the New York Times coverage of mass public shooting incidents occurring in the United States from 1966 to 2016. A comparison between media coverage and actual incidents is used to identify the characteristics influencing the newsworthiness of mass public shootings. This work expands the breadth and depth of media and mass public shooting research, strengthening the validity of previous findings, and identifying new characteristics influencing newsworthiness. Findings indicate significant predictors of newsworthiness include higher casualties and injuries, as well as perpetrators that are young, Middle Eastern, and ideologically motivated. School shootings are more likely to receive any coverage, and all non-workplace shootings receive salient levels of coverage. An incident is also more likely to receive any coverage if a combination of weapons is used. These findings have important implications for public knowledge and perceptions of mass public shootings.     

Policy Monitoring and Ministerial Survival: Evidence from Multiparty Presidentialism

Studies on policy monitoring and ministerial survival within coalition governments are usually conducted separately. In this study, we bring these topics together and argue that the strategy of coalition partners to oversee the implementation of one another's policies has surprising consequences on the duration of office-holding ministers. Our main theoretical insight suggests that the degree to which ministers behave as faithful agents of the government depends on their expectations about their partners' monitoring behavior, such that when they expect to be under high scrutiny, they moderate their drifting behavior. Using evidence from legislative information requests on the activities of individual ministers over all multiparty cabinets formed in Brazil between 1995 and 2014, we demonstrate that: (1) greater policy monitoring by coalition partners is observed under more ideologically heterogeneous cabinets, and (2) more frequent policy-monitoring efforts by coalition partners lead to a lower ministerial replacement within the government term.

NAFTA,tourism, and environment in Mexico

The purpose of this paper is to determine how NAFTA influenced the Mexican tourism sector and its effects on the environment. The linkage between the tourism sector and NAFTA is done through the analysis of foreign direct investment and cross-border trade in services. The quantitative section of the paper focuses on analyzing commercial presence in the form of hotels and restaurants, as well as the use of services abroad. The paper concludes that NAFTA represented greater certainty to investors but was not the main driver behind the investments in tourism services. The analysis of visitors from US and Canada in Mexico recognizes that NAFTA did not have significant impact on the tourism flow. NAAEC, on the other hand, serves in this research as a qualitative connection between tourism sector and the environment for attending to citizen submissions on failures in environmental law enforcement in Mexico regarding tourism projects. It is included with an economic-environmental balance in Cancun—which shows that the greatest environmental impact is of global importance: CO₂ released into the air by air transportation, followed by the local impact of water consumption, waste generation, and electricity usage, in that order.     

The "coffin fly"Conicera tibialis (Diptera: Phoridae) breeding on buried human remains after a postmortem interval of 18 years

The "coffin fly,"Conicera tibialis Schmitz (Order: Diptera, Family: Phoridae), is well known for its frequent occurrence on buried corpses, in some cases after postmortem intervals of even 3-5 years. The present report describes the presence of a large amount of individuals of C. tibialis inside the coffin of a buried human corpse exhumed 18 years after death in central Spain. Adults, some of them newly emerged, and empty puparia were found in connection with the remains. Such postmortem interval is significantly longer than previously known for this species and raises the question on the current state of knowledge about the use of insects for estimating the postmortem interval in old, buried remains.
